            "Year" means the calendar year.

            Section 1.2 Computation of Time Periods

            In this Agreement, in the computation of periods of time from a
specified date to a later specified date, the word "from" means "from and

            Section 1.3 Quantities

            In any Loan Document, in all instances where the same Dollar amount,
time period, percentage or other quantity is expressed both using numerals and
fully written out, the latter expression shall prevail over the expression using

            Section 1.4 Accounting Terms and Principles

            (a) Except as set forth below, all accounting terms not specifically

            (b) If any change in the accounting principles used in the

(Financial Statements) is hereafter required or permitted by the rules,
regulations, pronouncements and opinions of the Financial Accounting Standards
Board or the American Institute of Certified Public Accountants (or any
successors thereto) and such change is adopted by the Borrower with the
agreement of the Borrower's Accountants and results in a change in any
calculation required by Article V (Financial Covenants) or Article VIII
(Negative Covenants) had such accounting change not occurred, the parties hereto
agree to enter into negotiations in order to amend such provisions so as to
equitably reflect such change with the desired result that the criteria for
evaluating compliance with such covenants by the Borrower shall be the same
after such change as if such change had not been made; provided, however, that
no change in GAAP that would affect a calculation that measures compliance with
any covenant contained in Article V (Financial Covenants) or VIII (Negative
Covenants) shall be given effect until such provisions are amended to reflect
such changes in GAAP.

                                   ARTICLE II

                                 THE FACILITIES

            Section 2.1 The Commitments

            On the terms and subject to the conditions contained in this
Agreement, each Lender severally agrees to make loans (each a "Revolving Loan")
to the Borrower from time to time on any Business Day during the period from the
date hereof until the Termination Date in an aggregate principal amount at any
time outstanding (for all such loans by such Lender) not to exceed such Lender's
Commitment; provided, however, that at no time shall any Lender be obligated
pursuant to this Section 2.1 (The Commitments) to make a Revolving Loan to the
extent that the aggregate Outstandings, after giving effect to such Revolving
Loan, would exceed the Maximum Credit in effect at such time. Within the limits
of each Lender's Commitment, amounts of Revolving Loans repaid may be reborrowed
under this Section 2.1 on the terms and subject to the conditions contained in
this Section 2.1 and the remainder of this Agreement.

            Section 2.2 Borrowing Procedures

            (a) Form of Notice of Borrowing. Each Borrowing shall be made on
notice given by the Borrower to the Administrative Agent not later than 1:00
P.M. (New York City time) (i) one (1) Business Day, in the case of a Borrowing
of Base Rate Loans and (ii) three (3) Business Days, in the case of a Borrowing
of Eurodollar Rate Loans, prior to the date of the proposed Borrowing. Each such
notice shall be in substantially the form of Exhibit B (Form of Notice of
Borrowing) (a "Notice of Borrowing"), specifying therein (A) the date of such
proposed Borrowing, (B) the aggregate amount of such proposed Borrowing, (C)
whether any portion of the proposed Borrowing will be of Base Rate Loans or
Eurodollar Rate Loans, (D) the initial Interest Period or Periods for any such
Eurodollar Rate Loans and (E) the Available Credit (after giving effect to the
proposed Borrowing). The Revolving Loans shall be made as Base Rate Loans
unless, subject to Section 2.14 (Special Provisions Governing Eurodollar Rate
Loans), the Notice of Borrowing specifies that all or a portion thereof shall be
Eurodollar Rate Loans. Each Borrowing of Eurodollar Rate Loans shall be in an
aggregate amount of two Eurodollar Borrowing Units or an integral multiple of
Eurodollar Borrowing Units in excess thereof; provided, however, that the
aggregate amount of the Eurodollar Rate Loans for each Interest Period must be
in an amount of two Eurodollar Borrowing Units or an integral multiple of
Eurodollar Borrowing Units in excess thereof.

            (b) Disbursement. The Administrative Agent shall give to each Lender
prompt notice of the Administrative Agent's receipt of a Notice of Borrowing
and, if Eurodollar Rate Loans are properly requested in such Notice of
Borrowing, the applicable interest rate determined pursuant to Section 2.10(b)
(Interest). Each Lender shall, before 11:00 A.M. (New York City time) on the
date of the proposed Borrowing, make available for the account of its Applicable
Lending Office to the Administrative Agent at its address referred to in Section
11.12 (Notices, Etc.), in immediately available funds, such Lender's Ratable
Portion of such proposed Borrowing. After the Administrative Agent's receipt of
such funds and upon fulfillment of the applicable conditions set forth in
Sections 3.1 (Conditions Precedent to the Effectiveness of this Agreement), 3.2
(Conditions Precedent to Each Loan and Letter of Credit) and 3.4 (Post Closing
Conditions), the Administrative Agent shall make such funds available to the
Borrower.

                                                                CREDIT AGREEMENT

            (c) Assumption of Lender Funding. Unless the Administrative Agent
shall have received notice from a Lender prior to the date of any proposed
Borrowing that such Lender shall not make available to the Administrative Agent
such Lender's Ratable Portion of such Borrowing, the Administrative Agent may
assume that such Lender has made such Ratable Portion available to the
Administrative Agent on the date of such Borrowing in accordance with this
Section 2.2 and the Administrative Agent may, in reliance upon such assumption,
make available to the Borrower on such date a corresponding amount. If and to
the extent that such Lender shall not have so made such Ratable Portion
available to the Administrative Agent, such Lender and the Borrower severally
agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Administrative Agent, at (i) in the case of the Borrower, the
interest rate applicable at the time to the Loans comprising such Borrowing and
(ii) in the case of such Lender, the Federal Funds Rate for the first Business
Day and thereafter at the interest rate applicable at the time to the Loans
comprising such Borrowing. If such Lender shall repay to the Administrative
Agent such corresponding amount, such amount so repaid shall constitute such
Lender's Loan as part of such Borrowing for purposes of this Agreement. If the
Borrower shall repay to the Administrative Agent such corresponding amount, such
payment shall not relieve such Lender of any obligation it may have hereunder to
the Borrower.

            (d) Independence of Funding Obligations. The failure of any Lender
to make the Loan or any payment required by it hereunder on the date specified
therefor, including any payment in respect of its participation in Swing Loans
and Letter of Credit Obligations (a "Non-Funding Lender"), shall not relieve any
other Lender of its obligations to make such Loan or payment on such date but no
such other Lender shall be responsible for the failure of any Non-Funding Lender
to make a Loan or payment required under this Agreement.

            (e) Administrative Agent's Option. Notwithstanding anything to the
contrary contained herein or in Section 2.3(a) (Swing Loans), if any Notice of
Borrowing requests a Borrowing of Base Rate Loans, the Administrative Agent may,
at its option and in its sole discretion, make a Swing Loan available to the
Borrower in an amount up to but not to exceed the amount of such requested
Borrowing, and the aggregate amount of the requested Borrowing shall be reduced
accordingly by the principal amount of such Swing Loan, if made.

            Section 2.3 Swing Loans

            (a) Terms of the Swing Loans. On the terms and subject to the
conditions contained in this Agreement, the Swing Loan Lender shall make loans
(each a "Swing Loan") otherwise available to the Borrower under the Facility
from time to time on any Business Day during the period from the date hereof
until the Termination Date in an aggregate principal amount at any time
outstanding at any time not to exceed the Swing Loan Maximum Amount; provided,
however, that the Swing Loan Lender shall not make any Swing Loan to the extent
that, after giving effect to such Swing Loan, the aggregate Obligations would
exceed the Maximum Credit. The Swing Loan Lender shall be entitled to rely on
the most recent Borrowing Base Certificate delivered to the Administrative
Agent. Each Swing Loan shall be a Base Rate Loan and in an aggregate amount of
not less than one hundred thousand Dollars ($100,000). Within the limits set
forth in the first sentence of this clause (a), amounts of Swing Loans repaid
may be reborrowed under this clause (a). Within the limits set forth in the
first sentence of this clause (a), amounts prepaid pursuant to Section 2.8
(Optional Prepayments) may be reborrowed under this clause (a).

            (b) Notice of Borrowing. In order to request a Swing Loan, the
Borrower shall telecopy (or forward by electronic mail or similar means) to the
Administrative Agent a duly completed request setting forth the date, the
requested amount and date of the Swing Loan (a "Swing Loan Request"), to be
received by the Administrative Agent not later than 1:00 P.M. (New York City
time) on the day of the proposed borrowing. The Administrative Agent shall
promptly notify the Swing Loan Lender of the details of the requested Swing
Loan. Subject to the terms of this Agreement, the Swing Loan Lender shall make a
Swing Loan available to the Administrative Agent and, in turn, the
Administrative Agent shall make such amounts available to the Borrower on the
date of the relevant Swing Loan Request. The Swing Loan Lender shall not make
any Swing Loan in the period commencing on the first Business Day after it
receives written notice from any Lender that one or more of the conditions
precedent contained in Section 3.2 (Conditions Precedent to Each Loan and Letter
of Credit) shall not on such date be satisfied and ending when such conditions
are satisfied. The Swing Loan Lender shall not otherwise be required to
determine that, or take notice whether, the conditions precedent set forth in
Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) have been
satisfied in connection with the making of any Swing Loan.

            (c) Periodic Notifications. The Swing Loan Lender shall notify the
Administrative Agent in writing (which writing may be a telecopy or electronic
mail) weekly, by no later than 10:00 A.M. (New York City time) on the first
Business Day of each week, of the aggregate principal amount of its Swing Loans
then outstanding.

            (d) Payment on Demand. The Swing Loan Lender may demand at any time
that each Lender pay to the Administrative Agent, for the account of the Swing
Loan Lender, in the manner provided in clause (e) below, such Lender's Ratable
Portion of all or a portion of the outstanding Swing Loans, which demand shall
be made through the Administrative Agent, shall be in writing and shall specify
the outstanding principal amount of Swing Loans demanded to be paid.

            (e) Settlement of the Swing Loans. The Administrative Agent shall
forward each notice referred to in clause (c) above and each demand referred to
in clause (d) above to each Lender on the day such notice or such demand is
received by the Administrative Agent (except that any such notice or demand
received by the Administrative Agent after 2:00 P.M. (New York City time) on any
Business Day or any such demand received on a day that is not a Business Day
shall not be required to be forwarded to the Lenders by the Administrative Agent
until the next succeeding Business Day), together with a statement prepared by
the Administrative Agent specifying the amount of each Lender's Ratable Portion
of the aggregate principal amount of the Swing Loans stated to be outstanding in
such notice or demanded to be paid pursuant to such demand, and, notwithstanding
whether or not the conditions precedent set forth in Section 3.1 (Conditions
Precedent to the Effectiveness of this Agreement) or 3.2 (Conditions Precedent
to Each Loan and Letter of Credit) shall have been satisfied (which conditions
precedent the Lenders hereby irrevocably waive), each Lender shall, before 11:00
A.M. (New York City time) on the Business Day next succeeding the date of such
Lender's receipt of such written statement, make available to the Administrative
Agent, in immediately available funds, for the account of such Swing Loan
Lender, the amount specified in such statement. Upon such payment by a Lender,
such Lender shall, except as provided in clause (f) below, be deemed to have
made a Revolving Loan to the Borrower. The Administrative Agent shall use such
funds to repay the Swing Loans to the Swing Loan Lender. To the extent that any

Lender fails to make such payment available to the Administrative Agent for the
account of the Swing Loan Lender, the Borrower shall repay such Swing Loan on
demand.

            (f) Pro-Rata Participation Upon Default. Upon the occurrence of a
Default under Section 9.1(i) (Events of Default), each Lender shall acquire,
without recourse or warranty, an undivided participation in each Swing Loan
otherwise required to be repaid by such Lender pursuant to clause (e) above,
which participation shall be in a principal amount equal to such Lender's
Ratable Portion of such Swing Loan, by paying to the Swing Loan Lender on the
date on which such Lender would otherwise have been required to make a payment
in respect of such Swing Loan pursuant to clause (e) above, in immediately
available funds, an amount equal to such Lender's Ratable Portion of such Swing
Loan. If such amount is not in fact made available by such Lender to the Swing
Loan Lender on such date, the Swing Loan Lender shall be entitled to recover
such amount on demand from such Lender together with interest accrued from such
date at the Federal Funds Rate for the first Business Day after such payment was
due and thereafter at the rate of interest then applicable to Base Rate Loans.

            (g) Post-Default Distribution of Payments. From and after the date
on which any Lender is deemed to have made a Revolving Loan with respect to any
Swing Loan pursuant to clause (e) above or purchases an undivided participation
interest in a Swing Loan pursuant to clause (f) above, a Swing Loan Lender shall
promptly distribute to such Lender such Lender's Ratable Portion of all payments
of principal of and interest received by the Swing Loan Lender on account of
such Swing Loan other than those received from a Lender pursuant to clause (e)
or (f) above.

            Section 2.4 Letters of Credit

            (a) Obligation to Issue/Amend. On the terms and subject to the
conditions contained in this Agreement, each Issuer agrees to Issue, one or more

from time to time during the period commencing on the Effective Date and ending
thirty (30) days prior to the Scheduled Termination Date or such later date
prior to the Scheduled Termination Date as may be agreed to by the
Administrative Agent; provided, however, that no Issuer shall be under any
obligation to Issue any Letter of Credit if:

                  (i) any order, judgment or decree of any Governmental
      Authority shall purport by its terms to enjoin or restrain such Issuer
      from Issuing such Letter of Credit or any Requirement of Law applicable to
      such Issuer or any request or directive (whether or not having the force
      of law) from any Governmental Authority with jurisdiction over such Issuer
      shall prohibit, or request that such Issuer refrain from, the Issuance of
      letters of credit generally or such Letter of Credit in particular or
      shall impose upon such Issuer with respect to such Letter of Credit any
      restriction or reserve or capital requirement (for which such Issuer is
      not otherwise compensated) not in effect on the date of this Agreement or
      result in any unreimbursed loss, cost or expense which was not applicable,
      in effect or known to such Issuer as of the date of this Agreement and
      which such Issuer in good faith deems material to it;

                  (ii) such Issuer shall have received written notice from the
      Administrative Agent, any Lender or the Borrower, on or prior to the
      requested date of Issuance of such Letter of Credit, that one or more of
      the applicable conditions contained in Section 3.1 (Conditions Precedent
      to the Effectiveness of this Agreement), 3.2

                  (vi) such Letter of Credit is not denominated in Dollars.

None of the Lenders (other than the Issuers in their capacity as such) shall
have any obligation to Issue any Letter of Credit. Any Letter of Credit which
has been Issued hereunder may be amended at any time to reduce the amount
outstanding thereunder; any Letter of Credit Request which seeks to increase the
amount outstanding under a Letter of Credit shall be subject to the same
conditions set forth hereinabove for Issuance.

            (b) Expiration Date. In no event shall the expiration date of any
Letter of Credit (i) be more than one (1) year after the date of issuance
thereof or (ii) be less than seven (7) days prior to the Scheduled Termination
Date; provided, however, that any Letter of Credit with a one-year term may
provide for the renewal thereof for additional one-year periods (which shall in
no event extend beyond the expiry date referred to in clause (ii) above.

            (c) Contents of Letter of Credit Request. In connection with the
Issuance or amendment of each Letter of Credit, the Borrower shall give the
relevant Issuer and the Administrative Agent at least two (2) Business Days'
prior written notice, in substantially the form of Exhibit I (Form of Letter of
Credit Request) (or in such other written or electronic form as is acceptable to
the Issuer), of the requested Issuance or amendment of such Letter of Credit (a
"Letter of Credit Request"). Such notice shall be irrevocable and shall specify:
the Issuer of such Letter of Credit; the stated amount of the Letter of Credit
requested or to be amended, which in the case of an Issuance such stated amount
shall not be less than two hundred and fifty thousand Dollars ($250,000); the
date of Issuance or amendment of such requested Letter of Credit (which day
shall be a Business Day); the date on which such Letter of Credit is to expire

conditions set forth in this Section 2.4, the relevant Issuer shall, on the
requested date, Issue a Letter of Credit on behalf of the Borrower in accordance
with such Issuer's usual and customary business practices. No Issuer shall Issue
any Letter of Credit in the period commencing on the first Business Day after it
receives written notice from any Lender that one or more of the conditions
precedent contained in Section 3.2 (Conditions Precedent to Each Loan and Letter
of Credit) shall not on such date be satisfied and ending when such conditions
are satisfied. The relevant Issuer shall not

otherwise be required to determine that, or take notice whether, the conditions
precedent set forth in Section 3.2 (Conditions Precedent to Each Loan and Letter
of Credit) have been satisfied in connection with the Issuance of any Letter of
Credit.

            (e) Compliance with Conditions Precedent. On the date of the
proposed Issuance of the Letter of Credit, the Administrative Agent shall
confirm to the relevant Issuer that the applicable conditions set forth in
Section 3.1 (Conditions Precedent to the Effectiveness of this Agreement), 3.2
(Conditions Precedent to Each Loan and Letter of Credit), and 3.4 (Post Closing
Conditions) are satisfied.

            (f) Execution of Letter of Credit Reimbursement Agreement. If
requested by the relevant Issuer, prior to the Issuance of each Letter of Credit
by such Issuer and as a condition of such Issuance and of the participation of
each Lender in the Letter of Credit Obligations arising with respect thereto,
the Borrower shall have delivered to such Issuer a letter of credit
reimbursement agreement, in such form as the Issuer may employ in its ordinary
course of business for its own account (a "Letter of Credit Reimbursement
Agreement"), signed by the Borrower, and such other documents or items as may be
required pursuant to the terms thereof. In the event of any conflict between the
terms of any Letter of Credit Reimbursement Agreement and this Agreement, the
terms of this Agreement shall govern.

            (g) Obligations of the Issuer. Each Issuer shall:

                  (i) give the Administrative Agent written notice (or
      telephonic notice confirmed promptly thereafter in writing), which writing
      may be a telecopy or electronic mail, of the Issuance of a Letter of
      Credit Issued by it, of all drawings under a Letter of Credit issued by it
      and the payment (or the failure to pay when due) by the Borrower of any
      Reimbursement Obligation when due (which notice the Administrative Agent
      shall promptly transmit by telecopy, electronic mail or similar
      transmission to each Lender);

                  (ii) upon the request of any Lender, furnish to such Lender
      copies of any Letter of Credit to which such Issuer is a party; and

                  (iii) no later than ten (10) Business Days following the last
      day of each calendar month, provide to the Administrative Agent (and the
      Administrative Agent shall provide a copy to each Lender requesting the
      same) and the Borrower separate schedules for Documentary and Standby
      Letters of Credit issued by it, in form and substance reasonably
      satisfactory to the Administrative Agent, setting forth the aggregate
      Letter of Credit Obligations outstanding at the end of each month and any
      information requested by the Borrower or the Administrative Agent relating
      thereto.

            (h) Lenders' Purchase of Interest and Participation. Immediately
      upon the issuance by an Issuer of a Letter of Credit in accordance with
      the terms and conditions of this Agreement, such Issuer shall be deemed to
      have sold and transferred to each Lender, and each Lender shall be deemed
      irrevocably and unconditionally to have purchased and received from such
      Issuer, without recourse or warranty, an undivided interest and
      participation, to the extent of such Lender's Ratable Portion, in such
      Letter of Credit and the obligations of the Borrower with respect thereto
      (including all Letter of Credit Obligations with respect thereto) and any
      security therefor and guaranty pertaining thereto.

                                                                CREDIT AGREEMENT

            (i) Payment Obligations. The Borrower agrees to pay to the Issuer of
any Letter of Credit the amount of all Reimbursement Obligations owing to such
Issuer under any Letter of Credit issued for its account no later than the date
(the "Reimbursement Date") that is one (1) Business Day after the Borrower
receives written notice from such Issuer that payment has been made under such
Letter of Credit, irrespective of any claim, set-off, defense or other right
that the Borrower may have at any time against such Issuer or any other Person.
In the event that any Issuer makes any payment under any Letter of Credit and
the Borrower shall not have repaid such amount to such Issuer pursuant to this
clause (i) or such payment is rescinded or set aside for any reason, such
Reimbursement Obligation shall be payable on demand with interest thereon
computed from (i) the date on which such Reimbursement Obligation arose to the
Reimbursement Date, at the rate of interest applicable to Base Rate Loans and
(ii) the Reimbursement Date to the date of repayment in full in cash, at the
rate of interest applicable to past due Revolving Loans bearing interest at a
rate based on the Base Rate during such period, and such Issuer shall promptly
notify the Administrative Agent, which shall promptly notify each Lender of such
failure, and each Lender shall promptly and unconditionally pay to the
Administrative Agent for the account of such Issuer the amount of such Lender's
Ratable Portion of such payment in Dollars and in immediately available funds.
If the Administrative Agent so notifies such Lender prior to 11:00 A.M. (New
York time) on any Business Day, such Lender shall make available to the
Administrative Agent for the account of such Issuer its Ratable Portion of the
amount of such payment on such Business Day in immediately available funds. Upon
such payment by a Lender, such Lender shall, except during the continuance of a
Default or Event of Default under Section 9.1(f) (Events of Default) and
notwithstanding whether or not the conditions precedent set forth in Section 3.2
(Conditions Precedent to Each Loan and Letter of Credit) shall have been
satisfied (which conditions precedent the Lenders hereby irrevocably waive), be
deemed to have made a Revolving Loan to the Borrower in the principal amount of
such payment. Whenever any Issuer receives from the Borrower a payment of a
Reimbursement Obligation as to which the Administrative Agent has received for
the account of such Issuer any payment from a Lender pursuant to this clause
(i), such Issuer shall pay to the Administrative Agent and the Administrative
Agent shall promptly pay to each Lender, in immediately available funds, an
amount equal to such Lender's Ratable Portion of the amount of such payment
adjusted, if necessary, to reflect the respective amounts the Lenders have paid
in respect of such Reimbursement Obligation.

            (j) Obligations Absolute. The Borrower's obligation to pay each
Reimbursement Obligation and the obligations of the Lenders to make payments to
the Administrative Agent for the account of the Issuers with respect to Letters
of Credit 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, including the occurrence of any Default or Event
of Default, and irrespective of:

                  (i) any lack of validity or enforceability of any Letter of
      Credit or any Loan Document, or any term or provision therein;

                  (ii) any amendment or waiver of or any consent to departure
      from all or any of the provisions of any Letter of Credit or any Loan
      Document;

                  (iii) the existence of any claim, set off, defense or other
      right that the Borrower, any other party guaranteeing, or otherwise
      obligated with, the Borrower, any Subsidiary or other Affiliate thereof or
      any other Person may at any time have against the beneficiary under any
      Letter of Credit, any Issuer, the Administrative Agent or any

      Lender or any other Person, whether in connection with this Agreement, any
      other Loan Document or any other related or unrelated agreement or
      transaction;

                  (iv) any draft or other document presented under a Letter of
      Credit proving to be forged, fraudulent, invalid or insufficient in any
      respect or any statement therein being untrue or inaccurate in any
      respect;

                  (v) payment by the Issuer 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; and

                  (vi) any other act or omission to act or delay of any kind of
      the Issuer, the Lenders, the Administrative Agent or any other Person or
      any other event or circumstance whatsoever, whether or not similar to any
      of the foregoing, that might, but for the provisions of this Section 2.4,
      constitute a legal or equitable discharge of the Borrower's obligations
      hereunder.

Any action taken or omitted to be taken by the relevant Issuer under or in
connection with any Letter of Credit, if taken or omitted in the absence of
gross negligence or willful misconduct, shall not put such Issuer under any
resulting liability to the Borrower or any Lender. In determining whether drafts
and other documents presented under a Letter of Credit comply with the terms
thereof, the Issuer may accept documents that appear on their face to be in
order, without responsibility for further investigation, regardless of any
notice or information to the contrary and, in making any payment under any
Letter of Credit, the Issuer may rely exclusively on the documents presented to
it under such Letter of Credit as to any and all matters set forth therein,
including reliance on the amount of any draft presented under such Letter of
Credit, whether or not the amount due to the beneficiary thereunder equals the
amount of such draft and whether or not any document presented pursuant to such
Letter of Credit proves to be insufficient in any respect, if such document on
its face appears to be in order, and whether or not any other statement or any
other document presented pursuant to such Letter of Credit proves to be forged
or invalid or any statement therein proves to be inaccurate or untrue in any
respect whatsoever, and any noncompliance in any immaterial respect of the
documents presented under such Letter of Credit with the terms thereof shall, in
each case, be deemed not to constitute willful misconduct or gross negligence of
the Issuer.

            (k) Non-Payment by a Lender. If and to the extent such Lender shall
not have so made its Ratable Portion of the amount of the payment required by
clause (i) (Payment Obligations of the Borrower) above available to the
Administrative Agent for the account of such Issuer, such Lender agrees to pay
to the Administrative Agent for the account of such Issuer forthwith on demand
such amount together with interest thereon, for the first (1st) Business Day
after payment was first due at the Federal Funds Rate, and thereafter until such
amount is repaid to the Administrative Agent for the account of such Issuer, at
the rate per annum applicable to Base Rate Loans under the Facility. The failure
of any Lender to make available to the Administrative Agent for the account of
such Issuer its Ratable Portion of any such payment shall not relieve any other
Lender of its obligation hereunder to make available to the Administrative Agent
for the account of such Issuer its Ratable Portion of any payment on the date
such payment is to be made, but no Lender shall be responsible for the failure
of any other Lender to make available to the Administrative Agent for the
account of the Issuer such other Lender's Ratable Portion of any such payment.

            (l) Letters of Credit Issued Pursuant to the Receivables Purchase
Facility. Schedule 2.4 (Receivables Purchase Facility Existing Letters of
Credit) contains a schedule of certain letters of credit issued prior to the
Effective Date for the account of the Borrower pursuant to the Receivables
Purchase Facility. On the Effective Date, (i) such letters of credit, to the
extent outstanding, shall be automatically and without further action by the
parties thereto converted to Letters of Credit issued pursuant to this Section
2.4 for the account of the Borrower and subject to the provisions hereof, and
for this purpose the fees specified in Section 2.12(b) (Fees) shall be payable
(in substitution for any fees set forth in the applicable letter of credit
reimbursement agreements or applications relating to such letters of credit) as
if such letters of credit had been issued on the Effective Date, (ii) the
issuers of such Letters of Credit shall be deemed to be "Issuers" hereunder
solely for the purpose of maintaining such letters of credit, (iii) the face
amount of such letters of credit shall be included in the calculation of Letter
of Credit Obligations and (iv) all liabilities of the Borrower with respect to
such letters of credit shall constitute Obligations. No letter of credit
converted in accordance with this clause (l) shall be amended, extended or
renewed without the prior written consent of the Administrative Agent.

            Section 2.5 Reduction and Termination of the Commitments

            The Borrower may, upon at least three (3) Business Days' prior
notice to the Administrative Agent, terminate in whole or reduce in part ratably
the unused portions of the respective Commitments of the Lenders; provided,
however, that each partial reduction shall be in the aggregate amount of not
less than five million Dollars ($5,000,000) or an integral multiple of five
million Dollars ($5,000,000) in excess thereof.

            Section 2.6 Repayment of Loans

            The Borrower promises to repay the entire unpaid amount of the
Obligations on the Scheduled Termination Date (it being understood that other
provisions of this Agreement may require all or part of such Obligations to be
repaid earlier).

            Section 2.7 Evidence of Indebtedness

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

            (b) Maintenance of Accounts by Administrative Agent. The
Administrative Agent shall maintain accounts in accordance with its usual
practice in which it shall record (i) the amount of each Loan made and, if a
Eurodollar Rate Loan, the Interest Period applicable thereto, (ii) the amount of
any principal or interest due and payable by the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof, if applicable.

            (c) Accounts as Prima Facie Evidence. The entries made in the
accounts maintained pursuant to clauses (a) and (b) above shall, to the extent
permitted by applicable law, be prima facie evidence of the existence and
amounts of the obligations recorded therein; provided, however, that the failure
of any Lender or the Administrative Agent to maintain such

accounts or any error therein shall not in any manner affect the obligations of
the Borrower to repay the Loans in accordance with their terms.

            (d) Prompt Execution of Notes. Notwithstanding any other provision
of the Agreement, in the event that any Lender requests that the Borrower
execute and deliver a promissory note or notes payable to such Lender in order
to evidence the Indebtedness owing to such Lender by the Borrower hereunder, the
Borrower shall promptly execute and deliver a Note or Notes to such Lender
evidencing any Revolving Loans of such Lender, substantially in the form of
Exhibit A (Form of Revolving Credit Note), and the interests evidenced by such
note or notes shall at all times (including after assignment of all or part of
such interests) be evidenced by one or more Notes payable to the payee named
therein or its registered assigns.

            Section 2.8 Optional Prepayments

            The Borrower may prepay the outstanding principal amount of the
Revolving Loans in whole or ratably in part at any time, together with accrued
interest to the date of such prepayment on the principal amount prepaid (but
shall have no right to prepay the principal amount of any Revolving Loan other
than as provided in this Section 2.8); provided, however, that if any prepayment
of any Eurodollar Rate Loan is made by the Borrower other than on the last day
of an Interest Period for such Loan, the Borrower shall also pay any amounts
owing pursuant to Section 11.4(b) (Indemnities).

            Section 2.9 Mandatory Prepayments

            (a) Proceeds of Asset Sales, Equity Issuances, Etc. Upon receipt by
the Borrower or any of its Subsidiaries of Net Cash Proceeds arising (i) from an
Asset Sale, Property Loss Event or Debt Issuance, the Borrower shall immediately
prepay the Loans (or provide cash collateral in respect of Letters of Credit) in
an amount equal to one hundred percent (100%) of such Net Cash Proceeds and (ii)
from an Equity Issuance, the Borrower shall immediately prepay the Loans in an
amount equal to fifty percent (50%) of such Net Cash Proceeds; provided,
however, that in the case of any Net Cash Proceeds arising from a Reinvestment
Event, the Borrower shall prepay the Loans (or provide cash collateral in
respect of Letters of Credit) in an amount equal to the Reinvestment Prepayment
Amount applicable to such Reinvestment Event, if any, on the Reinvestment
Prepayment Date with respect to such Reinvestment Event and, pending application
of such proceeds as specified in the Reinvestment Notice, shall pay the same to
the Administrative Agent to be held in a Cash Collateral Account. Any such
mandatory prepayment shall be applied in accordance with clause (b) below.

            (b) Application. Any prepayments made by the Borrower required to be
applied in accordance with this clause (b) shall be applied as follows: first,
to repay the outstanding principal balance of the Swing Loans until such Swing
Loans shall have been repaid in full; second, to repay the outstanding principal
balance of the Revolving Loans until such Revolving Loans shall have been paid
in full; and then, to provide cash collateral for any Letter of Credit
Obligations in the manner set forth in Section 9.3 (Actions in Respect of
Letters of Credit) until one hundred and five percent (105%) of such Letter of
Credit Obligations have been fully cash collateralized in the manner set forth
therein.

            (c) Outstandings in Excess of Maximum Credit. If at any time, the
aggregate principal amount of Outstandings exceed the Maximum Credit at such
time, the Borrower shall forthwith prepay the Swing Loans first and then the
Revolving Loans then outstanding in an

amount equal to such excess. If any such excess remains after repayment in full
in cash of the aggregate outstanding Swing Loans and Revolving Loans, the
Borrower shall provide cash collateral for the Letter of Credit Obligations in
the manner set forth in Section 9.3 (Actions in Respect of Letters of Credit) to
the extent required to eliminate such excess.

            (d) Cash Dominion Periods. Except during the continuance of an Event
of Default (in which case Section 2.13(g) (Payments and Computations; Protective
Advances) shall apply), following notice from the Administrative Agent to the
Borrower, during the continuance of a Cash Dominion Period all available funds
in the Cash Collateral Account (other than an amount equal to any proceeds
arising from a Reinvestment Event that are held in the Cash Collateral Account
pending application of such proceeds as specified in a Reinvestment Notice)
shall be applied on a daily basis first to repay the outstanding principal
amount of the Swing Loans until such Swing Loans have been repaid in full;
second to repay the outstanding principal balance of the Revolving Loans until
such Revolving Loans shall have been repaid in full; and third to any other
Obligation then due and payable. The Administrative Agent agrees so to apply
such funds and the Borrower consents to such application. If, following such
application, there are no Loans outstanding and no other Obligations that are
then due and payable (and cash collateral in an amount equal to one hundred and
five percent (105%) of all outstanding Letter of Credit Obligations has been
provided), then the Administrative Agent shall cause any remaining funds in the
Cash Collateral Account to be paid at the written direction of the Borrower.

            Section 2.10 Interest

            (a) Rate. All Loans and the outstanding amount of all other
Obligations shall bear interest, in the case of Loans, on the unpaid principal
amount thereof from the date such Loans are made and, in the case of such other
Obligations, from the date such other Obligations are due and payable until, in
all cases, paid in full, except as otherwise provided in Section 2.10(b)
(Interest), as follows:

                  (i) if a Base Rate Loan or such other Obligation, at a rate
      per annum equal to the sum of (A) the Base Rate as in effect from time to
      time as interest accrues, plus (B) the Applicable Margin; and

                  (ii) if a Eurodollar Rate Loan, at a rate per annum equal to
      the sum of (A) the Eurodollar Rate determined for the applicable Interest
      Period, plus (B) the Applicable Margin in effect from time to time during
      such Eurodollar Interest Period.

            (b) Interest Payments. (i) Interest accrued on each Base Rate Loan
      (other than Swing Loans) shall be due and payable (A) on the first
      Business Day of each calendar month, commencing on the first such Business
      Day following the making of such Base Rate Loan and (B) if not previously
      paid in full, at maturity (whether by acceleration or otherwise) of such
      Base Rate Loan, (ii) interest accrued on Swing Loans shall be due and
      payable on the first Business Day of the immediately succeeding calendar
      month, (iii) interest accrued on each Eurodollar Rate Loan shall be due
      and payable (A) on the last day of each Interest Period applicable to such
      Loan and, if such Interest Period has a duration of more than three (3)
      months, on each day during such Interest Period occurring every three
      months after the first day of such Interest Period, (B) upon the payment
      or prepayment thereof in full or in part and (C) if not previously paid in
      full, at maturity (whether by acceleration or otherwise) of such
      Eurodollar Rate Loan and (iv) interest accrued on the amount of all other
      Obligations shall be due and payable (A) on the first Business Day of each
      calendar month, commencing on the first such Business

Day following the incurrence of such Obligation, (B) upon repayment thereof in
full or in part and (C) if not theretofore paid in full, at the time such other
Obligation becomes due and payable (whether by acceleration or otherwise).

            (c) Default Interest. Notwithstanding the rates of interest
specified in Section 2.10(a) (Interest) or elsewhere herein, effective
immediately upon the occurrence of an Event of Default, and for as long
thereafter as such Event of Default shall be continuing, the principal balance
of all Loans and the amount of all other Obligations then due and payable shall
bear interest at a rate that is two percent (2%) per annum in excess of the rate
of interest applicable to such Obligations from time to time.

            Section 2.11 Conversion and Continuation Options

            (a) Delivery of Notice of Conversion or Continuation. The Borrower
may elect (i) at any time, to convert Base Rate Loans (other than Swing Loans)
or any portion thereof to Eurodollar Rate Loans or (ii) at the end of any
applicable Interest Period, to convert Eurodollar Rate Loans or any portion
thereof into Base Rate Loans or to continue such Eurodollar Rate Loans or any
portion thereof for an additional Interest Period; provided, however, that the
aggregate amount of the Eurodollar Loans for each Interest Period must be in the
amount of two Eurodollar Borrowing Units or an integral multiple of Eurodollar
Borrowing Units in excess thereof. Each conversion or continuation shall be
allocated among the Loans of each Lender in accordance with its Ratable Portion.
Each such election shall be made by giving the Administrative Agent at least
three (3) Business Days' prior written notice (a "Notice of Conversion or
Continuation"), which shall in substantially the form of Exhibit C (Form of
Notice of Conversion or Continuation) hereto and shall specify (A) the amount
and type of Loan being converted or continued, (B) in the case of a conversion
to, or a continuation of, Eurodollar Rate Loans, the applicable Interest Period
and (C) in the case of a conversion, the date of conversion (which date shall be
a Business Day and, if a conversion from Eurodollar Rate Loans, shall also be
the last day of the applicable Interest Period).

            (b) Notice. The Administrative Agent shall promptly notify each
Lender of its receipt of a Notice of Conversion or Continuation and of the
options selected therein.

            (c) Event of Default; Failure to Give Appropriate Notice.
Notwithstanding the foregoing, no conversion in whole or in part of Base Rate
Loans to Eurodollar Rate Loans, and no continuation in whole or in part of
Eurodollar Rate Loans upon the expiration of any applicable Interest Period,
shall be permitted at any time at which (A) a Default or an Event of Default
shall have occurred and be continuing or (B) the continuation of, or conversion
into, a Eurodollar Rate Loan would violate any provision of Section 2.14
(Special Provisions Governing Eurodollar Rate Loans). If, within the time period
required under the terms of this Section 2.11, the Administrative Agent does not
receive a Notice of Conversion or Continuation from the Borrower containing a
permitted election to continue any Eurodollar Rate Loans for an additional
Interest Period or to convert any such Loans, then, upon the expiration of the
applicable Interest Period, such Loans shall be automatically converted to Base
Rate Loans. Each Notice of Conversion or Continuation shall be irrevocable.

            Section 2.12 Fees

            (a) Unused Commitment Fee. The Borrower agrees to pay to each Lender
a commitment fee accruing at the rate of the Unused Commitment Fee Rate on the
actual daily

amount by which the Commitment of such Lender exceeds such Lender's Ratable
Portion of the Outstandings less the amount of any outstanding Swing Loans (the
"Unused Commitment Fee") from the date hereof until the Termination Date,
payable in arrears (i) on the first Business Day of each calendar month,
commencing on the first such Business Day following the Effective Date and (ii)
on the Termination Date.

            (b) Additional Fees. The Borrower has agreed to pay to CUSA and
certain other Agents additional fees, the amount and dates of payment of which
are embodied in the Fee Letters.

            (c) Letter of Credit Fees. The Borrower agrees to pay the following
amounts with respect to Letters of Credit issued by any Issuer:

                  (i) to the Administrative Agent for the account of each Issuer
      of a Letter of Credit, with respect to each Letter of Credit issued by
      such Issuer, an issuance fee equal to XXX XXXXXXX XX XXX XXXXXXX XXXXXXX
      per annum of the maximum amount available from time to time to be drawn
      under such Letter of Credit, payable in arrears (x) on the first Business
      Day of each calendar month, commencing on the first such Business Day
      following the issuance of such Letter of Credit and (y) on the Termination
      Date;

                  (ii) to the Administrative Agent for the ratable benefit of
      the Lenders, with respect to each Letter of Credit, an amount equal to the
      Letter of Credit Fee on the average daily outstanding balance of such
      Letter of Credit for the immediately preceding month (or portion thereof
      or, in the case of clause (y) below, since the end of the last period in
      respect of which such fee was paid), payable in arrears (x) on the first
      Business Day of each calendar month, commencing on the first such Business
      Day following the issuance of such Letter of Credit and (y) on the
      Termination Date; provided, however, that during the continuance of an
      Event of Default, the Letter of Credit Fee shall be increased by two
      percent (2%) per annum and shall be payable on demand; and

                  (iii) to the Issuer of any Letter of Credit, with respect to
      the issuance, amendment or transfer of each Letter of Credit and each
      drawing made thereunder, documentary and processing charges in accordance
      with such Issuer's standard schedule for such charges in effect at the
      time of issuance, amendment, transfer or drawing, as the case may be.

            Section 2.13 Payments and Computations; Protective Advances

            (a) Payment Procedures. The Borrower shall make each payment
hereunder (including interest, fees and expenses) not later than 1:00 P.M. (New
York City time) on the day when due and payable, in Dollars, to the
Administrative Agent at its address referred to in Section 11.12 (Notices, Etc.)
in immediately available funds without set-off or counterclaim. During any Cash
Dominion Period, the Borrower authorizes the Administrative Agent to debit the
Facility on the day when due for interest and fees and, after ten Business Days'
notice, for expenses. The Administrative Agent shall promptly thereafter cause
to be distributed immediately available funds relating to the payment of
principal or interest or fees to the Lenders, in accordance with the application
of payments set forth in clauses (e) and (g) below, as applicable, for the
account of their respective Applicable Lending Offices and like funds relating

to the payment of any other amount payable to any Lender to such Lender for the
account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement; provided, however, that amounts
payable pursuant to Section 2.14(c) or (d) (Special Provisions Governing
Eurodollar Rate Loans), Section 2.15 (Capital Adequacy) or 2.16 (Taxes) shall be
paid only to the affected Lender or Lenders and amounts payable with respect to
Swing Loans shall be paid only to the Swing Loan Lender. Payments received by
the Administrative Agent after 1:00 P.M. (New York City time) shall be deemed to
be received on the next Business Day.

            (b) Computations of Interest. All computations of interest and of
fees shall be made by the Administrative Agent on the basis of a year of three
hundred and sixty (360) days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest and fees are payable. Each determination by the
Administrative Agent of an interest rate hereunder shall be conclusive and
binding for all purposes, absent manifest error.

            (c) Payments on Business Days; Order. Whenever any payment hereunder
shall be stated to be due on a day other than a Business Day, such payment shall
be made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest or fees, as the
case may be; provided, however, that if such extension would cause payment of
interest on or principal of any Eurodollar Rate Loan to be made in the next
calendar month, such payment shall be made on the immediately preceding Business
Day. All repayments of any Revolving Loans shall be applied as follows: first,
to repay such Loans outstanding as Base Rate Loans and then to repay such Loans
outstanding as Eurodollar Rate Loans, with those Eurodollar Rate Loans having
earlier expiring Eurodollar Interest Periods being repaid prior to those that
having expiring Eurodollar Interest Periods.

            (d) Assumption that Payment Has Been Made. Unless the Administrative
Agent shall have received notice from the Borrower prior to the date on which
any payment is due hereunder that the Borrower will not make such payment in
full, the Administrative Agent may assume that the Borrower has made such
payment in full to the Administrative Agent on such date and the Administrative
Agent may, in reliance upon such assumption, cause to be distributed to each
Lender on such due date an amount equal to the amount then due such Lender. If
and to the extent that the Borrower shall not have made such payment in full to
the Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon at the Federal Funds Rate, for the first Business Day, and,
thereafter, at the rate applicable to Base Rate Loans, for each day from the
date such amount is distributed to such Lender until the date such Lender repays
such amount to the Administrative Agent.

            (e) Application. Subject to the provisions of clause (g) below (and
except as otherwise provided in Section 2.9 (Mandatory Prepayments)), all
payments and any other amounts received by the Administrative Agent from or for
the benefit of the Borrower shall be applied as follows: first, to pay principal
of, and interest on, any portion of the Loans that the Administrative Agent may
have advanced pursuant to the express provisions of this Agreement on behalf of
any Lender, for which the Administrative Agent has not then been reimbursed by
such Lender or the Borrower; second, to pay all other Obligations then due and
payable; and then, as the Borrower so designates. Payments in respect of Swing
Loans received by the Administrative Agent shall be distributed to the Swing
Loan Lender; payments in respect of Revolving Loans received by the
Administrative Agent shall be distributed to each Lender in

accordance with such Lender's Ratable Portion; and all payments of fees and all
other payments in respect of any other Obligation shall be allocated among such
of the Lenders and Issuers as are entitled thereto and, for such payments
allocated to the Lenders, in proportion to their respective Ratable Portions.

            (f) Collateral Proceeds. The Borrower hereby irrevocably waives the
right to direct, after the occurrence and during the continuance of an Event of
Default, the application of any and all payments in respect of the Obligations
and any proceeds of Collateral, and agrees that the Administrative Agent may,
and, upon either (A) the written direction of the Requisite Lenders or (B) the
acceleration of the Obligations pursuant to Section 9.2 (Remedies), shall (x)
deliver a Blockage Notice to each Deposit Account Bank and (y) apply all
payments in respect of any Obligations and all funds on deposit in any Cash
Collateral Account (including all proceeds arising from a Reinvestment Event
that are held in the Cash Collateral Account pending application of such
proceeds as specified in a Reinvestment Notice) and all other proceeds of
Collateral in the following order:

            (i) first, to pay interest on and then principal of any portion of
the Revolving Loans that the Administrative Agent or any of its Affiliates may
have advanced on behalf of any Lender for which the Administrative Agent or such
Affiliate has not then been reimbursed by such Lender or the Borrower;

                  (ii) second, to pay interest on and then principal of any
      Swing Loan;

                  (iii) third, to pay any cash management fee or any Obligation
      due under any Hedging Contract with any Lender or any of its Affiliates;

                  (iv) fourth, to pay Obligations in respect of any expense
      reimbursements or indemnities then due the Administrative Agent or any of
      its Affiliates;

                  (v) fifth, to pay Obligations in respect of any expense
      reimbursements or indemnities then due to the Lenders and the Issuers;

                  (vi) sixth, to pay Obligations in respect of any fees then due
      to the Administrative Agent or any of its Affiliates, the Lenders and the
      Issuers;

                  (vii) seventh, to pay interest then due and payable in respect
      of the Loans and Reimbursement Obligations; and

                  (viii) eighth, to pay or prepay principal payments on the
      Loans and Reimbursement Obligations and to provide cash collateral for
      outstanding Letter of Credit Undrawn Amounts in the manner described in
      Section 9.3 (Actions in Respect of Letters of Credit), ratably to the
      aggregate principal amount of such Loans, Reimbursement Obligations and
      Letter of Credit Undrawn Amounts, to the ratable payment of all other
      Obligations;

provided, however, that, if sufficient funds are not available to fund all
payments to be made in respect of any Obligation described in any of clauses (i)
through (viii) above, the available funds being applied with respect to any such
Obligation (unless otherwise specified in such clause) shall be allocated to the
payment of such Obligations ratably, based on the proportion of the
Administrative Agent's and each Lender's or Issuer's interest in the aggregate
outstanding

Obligations described in such clauses. The order of priority set forth in this
clause (f) and the related provisions hereof are set forth solely to determine
the rights and priorities of the Administrative Agent, the Swing Loan Lender,
the Lenders, the Issuers and other Secured Parties as among themselves. The
order of priority set forth in clauses (i) through (viii) above of this may at
any time and from time to time be changed by the agreement of the Requisite
Lenders without necessity of notice to or consent of or approval by the
Borrower, any Secured Party which is not a Lender or Issuer or any other Person.
The order of priority set forth in clauses (i) through (v) above may be changed
only with the prior written consent of the Administrative Agent in addition to
the Requisite Lenders.

            (g) Payments from Loans; Protective Advances. At the option of the
Administrative Agent, principal on the Swing Loans, the Reimbursement
Obligations, interest, fees, expenses and other sums due and payable in respect
of the Revolving Loans, Swing Loans, and Protective Advances may be paid from
the proceeds of Swing Loans or Revolving Loans. The Borrower hereby authorizes
the Swing Loan Lender to make Swing Loans pursuant to Section 2.3 (Swing Loans)
and the Lenders to make Revolving Loans pursuant to Section 2.2 (Borrowing
Procedures) (and each Lender hereby agrees to make, regardless of whether, after
giving effect to such Revolving Loan, either the then effective aggregate
Commitment or the Borrowing Base at such time exceeds the Maximum Credit in
effect at such time), from time to time in the Swing Loan Lender's, or, in the
case of the Lenders, the Administrative Agent's discretion, Swing Loans or
Revolving Loans, as applicable, that in the aggregate amount of any and all
principal payable with respect to the Swing Loans and interest, fees, expenses
and other sums payable in respect of the Revolving Loans, Swing Loans and
Protective Advances, and further authorizes the Administrative Agent to give the
Lenders notice of any such Borrowing with respect to such Swing Loans and
Revolving Loans and to distribute the proceeds of such Swing Loans and Revolving
Loans to pay such amounts; provided, however, that the aggregate principal
amount outstanding in respect of such Swing Loans and Revolving Loans for
payments under this Section 2.13(g) shall not exceed five million Dollars
($5,000,000). The Borrower agrees that all such Swing Loans and Revolving Loans
so made shall be deemed to have been requested by it (irrespective of the
satisfaction of the conditions in Section 3.2 (Conditions Precedent to Each Loan
and Letter of Credit), which conditions the Lenders irrevocably waive in respect
of such Swing Loans and Revolving Loans) and directs that all proceeds thereof
shall be used to pay such amounts.

            Section 2.14 Special Provisions Governing Eurodollar Rate Loans

            (a) Determination of Interest Rate. The Eurodollar Rate for each
Interest Period for Eurodollar Rate Loans shall be determined by the
Administrative Agent pursuant to the procedures set forth in the definition of
"Eurodollar Rate." The Administrative Agent's determination shall be presumed to
be correct, absent manifest error, and shall be binding on the Borrower.

            (b) Interest Rate Unascertainable, Inadequate or Unfair. In the
event that: (i) the Administrative Agent determines that adequate and fair means
do not exist for ascertaining the applicable interest rates by reference to
which the Eurodollar Rate then being determined is to be fixed or (ii) the
Requisite Lenders notify the Administrative Agent that the Eurodollar Rate for
any Interest Period will not adequately reflect the cost to the Lenders of
making or maintaining such Loans for such Interest Period, the Administrative
Agent shall forthwith so notify the Borrower and the Lenders, whereupon each
Eurodollar Loan shall automatically, on the last day of the current Interest
Period for such Loan, convert into a Base Rate Loan and the obligations of

the Lenders to make Eurodollar Rate Loans or to convert Base Rate Loans into
Eurodollar Rate Loans shall be suspended until the Administrative Agent shall
notify the Borrower that the Requisite Lenders have determined that the
circumstances causing such suspension no longer exist.

            (c) Increased Costs. If at any time any Lender shall determine that
the introduction of, or any change in or in the interpretation of, any law,
treaty or governmental rule, regulation or order (other than any change by way
of imposition or increase of reserve requirements included in determining the
Eurodollar Rate) or the compliance by such Lender with any guideline, request or
directive promulgated or given on behalf of any central bank or other
Governmental Authority (whether or not having the force of law), there shall be
any increase in the cost to such Lender of agreeing to make or making, funding
or maintaining any Eurodollar Rate Loans, then the Borrower shall from time to
time, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such
increased cost. If any Lender becomes entitled to claim any additional amount
pursuant to this clause (c), it shall promptly notify the Borrower (with a copy
to the Administrative Agent) of the event by reason of which it has become so
entitled. A certificate as to the amount of such increased cost, submitted to
the Borrower and the Administrative Agent by such Lender, shall be conclusive
and binding for all purposes, absent manifest error.

            (d) Illegality. Notwithstanding any other provision of this
Agreement, if any Lender determines that the introduction of, or any change in
or in the interpretation of, any Requirement of Law shall make it unlawful, or
any central bank or other Governmental Authority shall assert that it is
unlawful, for any Lender or its Eurodollar Lending Office to make Eurodollar
Rate Loans or to continue to fund or maintain Eurodollar Rate Loans, then, on
notice thereof and demand therefor by such Lender to the Borrower through the
Administrative Agent, (i) the obligation of such Lender to make or to continue
Eurodollar Rate Loans and to convert Base Rate Loans into Eurodollar Rate Loans
shall be suspended, and each such Lender shall make a Base Rate Loan as part of
any requested Borrowing of Eurodollar Rate Loans and (ii) if the affected
Eurodollar Rate Loans are then outstanding, the Borrower shall immediately
convert each such Loan into a Base Rate Loan. If, at any time after a Lender
gives notice under this clause (d), such Lender determines that it may lawfully
make Eurodollar Rate Loans, such Lender shall promptly give notice of that
determination to the Borrower and the Administrative Agent, and the
Administrative Agent shall promptly transmit the notice to each other Lender.
The Borrower's right to request, and such Lender's obligation, if any, to make
Eurodollar Rate Loans, shall thereupon be restored.

            (e) Breakage Costs. In addition to all amounts required to be paid
by the Borrower pursuant to Section 2.10 (Interest), the Borrower shall
compensate each Lender, upon demand, for all losses, expenses and liabilities
(including any loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund or
maintain such Lender's Eurodollar Rate Loans to the Borrower but excluding any
loss of the Applicable Margin on the relevant Loans) that such Lender may
sustain (i) if for any reason a proposed Borrowing, conversion into or
continuation of Eurodollar Rate Loans does not occur on a date specified
therefor in a Notice of Borrowing or a Notice of Conversion or Continuation
given by a Borrower or in a telephonic request by it for borrowing or conversion
or continuation or a successive Interest Period does not commence after notice
therefor is given pursuant to Section 2.11(a) (Conversion and Continuation
Options), (ii) if for any reason any Eurodollar Rate

Loan is prepaid (including mandatorily pursuant to Section 2.9 (Mandatory
Prepayments)) on a date that is not the last day of the applicable Interest
Period, (iii) as a consequence of a required conversion of a Eurodollar Rate
Loan to a Base Rate Loan as a result of any of the events indicated in clause
(b) or (d) above or (iv) as a consequence of any failure by a Borrower to repay
Eurodollar Rate Loans when required by the terms hereof. The Lender making
demand for such compensation shall deliver to the Borrower concurrently with
such demand a written statement as to such losses, expenses and liabilities, and
this statement shall be conclusive as to the amount of compensation due to that
Lender, absent manifest error.

            Section 2.15 Capital Adequacy

            If at any time any Lender determines that (a) the adoption of, or
any change in, or in the interpretation of, any Requirement of Law regarding
capital adequacy, (b) compliance with any such Requirement of Law or (c)
compliance with any guideline or request or directive from any central bank or
other Governmental Authority (whether or not having the force of law) shall have
the effect of reducing the rate of return on such Lender's (or any Person
controlling such Lender's) capital as a consequence of its obligations
hereunder, or under or in respect of any Letter of Credit, to a level below the
level that such Lender or such Person could have achieved but for such adoption,
change, compliance or interpretation, then, upon demand from time to time by
such Lender (with a copy of such demand to the Administrative Agent), the
Borrower shall pay to the Administrative Agent for the account of such Lender,
from time to time as specified by such Lender, additional amounts sufficient to
compensate such Lender for such reduction. A certificate as to such amounts
submitted to the Borrower and the Administrative Agent by such Lender shall be
conclusive and binding for all purposes absent manifest error.

            Section 2.16 Taxes

            (a) Deduction of Taxes. Any and all payments by the Borrower under
each Loan Document shall be made free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding (i) in the
case of each Lender and the Administrative Agent (A) taxes measured by its net
income, and franchise taxes imposed on it, by the jurisdiction (or any political
subdivision thereof) under the laws of which such Lender or the Administrative
Agent (as the case may be) is organized and (B) any United States withholding
taxes payable with respect to payments under the Loan Documents under
Requirement of Laws in effect on the Effective Date (or, in the case of an
Eligible Assignee, the date of the Assignment and Acceptance) applicable to such
Lender or the Administrative Agent, as the case may be, but not excluding any
United States withholding taxes payable as a result of any change in such
Requirement of Laws occurring after the Effective Date (or the date of such
Assignment and Acceptance) and (ii) in the case of each Lender, taxes measured
by its net income, and franchise taxes imposed on it, by the jurisdiction in
which such Lender's Applicable Lending Office is located (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). If any Taxes shall be required by any
Requirement of Law to be deducted from, or in respect of, any sum payable under
any Loan Document to any Lender or the Administrative Agent (w) the sum payable
shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.16) such Lender or the Administrative Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (x) the Borrower shall make such deductions, (y) the
Borrower shall pay the full amount deducted to the relevant

taxing authority or other authority in accordance with applicable Requirements
of Law and (z) the Borrower shall deliver to the Administrative Agent evidence
of such payment.

            (b) Stamp or Documentary Taxes. In addition, the Borrower agrees to
pay any present or future stamp or documentary taxes or any other excise or
property taxes, charges or similar levies of the United States or any applicable
foreign jurisdiction, and all liabilities with respect thereto, arising from any
payment made under any Loan Document or from the execution, delivery or
registration of, or otherwise with respect to, any Loan Document (collectively,
"Other Taxes").

            (c) Indemnification. The Borrower shall indemnify each Lender and
the Administrative Agent for the full amount of Taxes and Other Taxes (including
any Taxes and Other Taxes imposed by any jurisdiction on amounts payable under
this Section 2.16) paid by such Lender or the Administrative Agent (as the case
may be) and any liability (including for penalties, interest and expenses)
arising therefrom or with respect thereto, whether or not such Taxes or Other
Taxes were correctly or legally asserted. This indemnification shall be made
within thirty (30) days from the date such Lender or the Administrative Agent
(as the case may be) makes written demand therefor.

            (d) Receipt. Within thirty (30) days after the date of any payment
of Taxes or Other Taxes, the Borrower shall furnish to the Administrative Agent,
at its address referred to in Section 11.12 (Notices, Etc.), the original or a
certified copy of a receipt evidencing payment thereof.

            (e) Survival. Without prejudice to the survival of any other
agreement of the Borrower hereunder, the agreements and obligations of the
Borrower contained in this Section 2.16 shall survive the payment in full of the
Obligations.

            (f) Non-U.S. Lenders. Prior to the Effective Date in the case of
each Non-U.S. Lender that is a signatory hereto, and on the date of the
Assignment and Acceptance pursuant to which it becomes a Lender in the case of
each other Non-U.S. Lender and from time to time thereafter if requested by the
Borrower or the Administrative Agent, each Non-U.S. Lender that is entitled at
such time to an exemption from United States withholding tax, or that is subject
to such tax at a reduced rate under an applicable tax treaty, shall provide the
Administrative Agent and the Borrower with two completed copies of (i) Form
W-8ECI (claiming exemption from withholding because the income is effectively
connected with a U.S. trade or business) or any successor form, (ii) Form W-8BEN
(claiming exemption from, or a reduction of, withholding tax under an income tax
treaty) or any successor form, (iii) in the case of a Non-U.S. Lender claiming
exemption under Sections 871(h) or 881(c) of the Code, a Form W-8BEN (claiming
exemption from withholding under the portfolio interest exemption) or any
successor form or (iv) any other applicable form, certificate or document
prescribed by the IRS certifying as to such Non-U.S. Lender's entitlement to
such exemption from United States withholding tax or reduced rate with respect
to all payments to be made to such Non-U.S. Lender under the Loan Documents.
Unless the Borrower and the Administrative Agent have received forms or other
documents satisfactory to them indicating that payments under any Loan Document
to or for a Non-U.S. Lender are not subject to United States withholding tax or
are subject to such tax at a rate reduced by an applicable tax treaty, the
Borrower or the Administrative Agent shall withhold taxes from such payments at
the applicable statutory rate.

            (g) Obligation to Try to Change Jurisdiction. Any Lender claiming
any additional amounts payable pursuant to this Section 2.16 shall use its
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to change the jurisdiction of its Applicable Lending Office if the
making of such a change would avoid the need for, or reduce the amount of, any
such additional amounts that would be payable or may thereafter accrue and would
not, in the sole determination of such Lender, be otherwise disadvantageous to
such Lender.

            Section 2.17 Substitution of Lenders

            In the event that (a)(i) any Lender makes a claim under Section
2.14(c) or (d) (Special Provisions Governing Eurodollar Rate Loans) or Section
2.15 (Capital Adequacy), (ii) it becomes illegal for any Lender to continue to
fund or make any Eurodollar Rate Loan and such Lender notifies the Borrower
pursuant to Section 2.14(e) (Special Provisions Governing Eurodollar Rate
Loans), (iii) the Borrower is required to make any payment pursuant to Section
2.16 (Taxes) that is attributable to any Lender or (iv) any Lender is a
Non-Funding Lender, (b) in the case of sub-clause (i) of clause (a) above, as a
consequence of increased costs in respect of which such claim is made, the
effective rate of interest payable to such Affected Lender under this Agreement
with respect to its Loans materially exceeds the effective average annual rate
of interest payable to the Requisite Lenders under this Agreement and (c)
Lenders holding at least seventy-five percent (75%) of the Commitments are not
subject to such increased costs or illegality, payment or proceedings (in each
case, any such Lender, an "Affected Lender"), the Borrower may substitute
another financial institution for such Affected Lender hereunder, upon
reasonable prior written notice (which written notice must be given within
ninety (90) days following the occurrence of any of the events described in
sub-clauses (i) through (iv) of clause (a) above) by the Borrower to the
Administrative Agent and the Affected Lender that the Borrower intends to make
such substitution, which substitute financial institution must be an Eligible
Assignee and, if not a Lender, reasonably acceptable to the Administrative
Agent; provided, however, that if more than one Lender claims increased costs,
illegality or right to payment arising from the same act or condition and such
claims are received by the Borrower within thirty (30) days of each other then
the Borrower may substitute all, but not (except to the extent the Borrower has
already substituted one of such Affected Lenders before the Borrower's receipt
of the other Affected Lenders' claim) less than all, Lenders making such claims.
In the event that the proposed substitute financial institution or other entity
is reasonably acceptable to the Administrative Agent and the written notice was
properly issued under this Section 2.17, the Affected Lender shall sell, and the
substitute financial institution or other entity shall purchase, pursuant to an
Assignment and Acceptance, all rights and claims of such Affected Lender under
the Loan Documents and the substitute financial institution or other entity
shall assume and the Affected Lender shall be relieved of such Commitments, and
all other prior unperformed obligations of the Affected Lender under the Loan
Documents (other than in respect of any damages (other than exemplary or

ended, certified by Ernst & Young, LLP, and the consolidated balance sheets of
the Borrower and its Subsidiaries as at June 30, 2001, and the related
consolidated statements of income, retained earnings and cash flows of the
Borrower and its Subsidiaries for the six (6) months then ended, certified by a
Responsible Officer of the Borrower, copies of which have been furnished to each
Lender, fairly present, subject, in the case of said balance sheets as at June

Material Subsidiaries has any material obligation, contingent liability or
liability for taxes, long-term leases or unusual forward or long-term commitment
that is not reflected in the Financial Statements referred to in Section 4.3(a)
(Financial Statements) or in the notes thereto or otherwise permitted by this
Agreement.

            (c) Projections. The Projections have been prepared by the Borrower

occurs, on a month by month basis for the balance of the Fiscal Years ending
December 31, 2001 and 2002, and on a year by year basis thereafter. The
Projections are based upon estimates and assumptions stated therein, all of
which the Borrower believes to be reasonable and fair in light of current
conditions and current facts known to the Borrower and, as of the Effective
Date, reflect the Borrower's good faith and reasonable estimates of the future
financial performance of the Borrower and its Subsidiaries and of the other
information projected therein for the periods set forth therein.

            Section 4.4 Legal Proceedings

            There are no pending, or, to the knowledge of the Borrower,
threatened, Legal Proceedings that may affect the Borrower or any of its
Material Subsidiaries or their respective properties before any Governmental
Authority other than those that, if determined adversely to any Loan Party,
would not have a Material Adverse Effect. The performance of any action by any
Loan Party required or contemplated by any Loan Document is not restrained or
enjoined (either temporarily, preliminarily or permanently).

            Section 4.5 Material Adverse Change

            Since June 30, 2001, there has been no Material Adverse Change and
there have been no events or developments that, in the aggregate, have had a

have no Material Adverse Effect.

            (c) Compliance with Requirements of Law. Each Title IV Plan is in
compliance in all material respects with applicable provisions of ERISA, the
Code and other Requirements of Law except for non-compliances that in the
aggregate would not have no Material Adverse Effect.

Affiliate Transaction involves aggregate payments or value in excess of ten
million Dollars ($10,000,000), the board of directors of the Borrower (including
a majority of the disinterested members of the board of directors of the
Borrower) approves such Affiliate Transaction and, in its good faith judgment,
believes that such Affiliate Transaction complies with clause (i) above as
evidenced by a board resolution promptly delivered to the Administrative Agent

      case may be, than those that could be obtained in a comparable arm's
      length transaction with a person that is not an Affiliate of the Borrower
      and (B) if such Affiliate Transactions involve aggregate payments or value
      in excess of ten million Dollars ($10,000,000), the board of directors of

and payable, without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by the Borrower; provided, however,
that upon the occurrence of the Events of Default specified in Section 9.1(i)
(Events of Default), (x) the Commitments of each Lender to make Loans and the
commitments of each Issuer to Issue Letters of Credit shall each automatically
be terminated and (y) the Loans, all such interest and all such amounts and
Obligations shall automatically become and be due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by the Borrower. In addition to the remedies set forth above,
each of the Administrative Agent may exercise any remedies provided for by the

hundred and five percent (105%) of the sum of all outstanding Letter of Credit
Obligations arising from the letters of credit issued by such Issuer. The
Administrative Agent may, from time to time after funds are deposited in any
Cash Collateral Account, apply funds then held in such Cash Collateral Account
to the payment of any amounts, in accordance with Section 2.13(f) (Payments and
Computations; Protective Advances), as shall have become or shall become due and
payable by the Borrower to the Issuers or Lenders in respect of the Letter of
Credit Obligations. The Administrative Agent shall promptly give written notice
of any such application; provided, however, that the failure to give such
written notice shall not invalidate any such application.

specified herein) and all Events of Default and Defaults (other than non-payment
of principal of and accrued interest on the Loans due and payable solely by
virtue of acceleration) shall be remedied or waived pursuant Section 11.1
(Amendments, Waivers, Etc.), then, upon the written consent of the Requisite
Lenders and written notice to the Borrower, the termination of the Commitments
or the acceleration and their consequences may be rescinded and annulled;
provided, however, that such action shall not affect any subsequent Event of
Default or Default or impair any right or remedy consequent thereon. The
provisions of the preceding sentence are intended merely to bind the Lenders and
the Issuers to a decision that may be made at the election of the Requisite
Lenders; they are not intended to benefit the Borrower and do not give the
Borrower the right to require the Lenders to rescind or annul any acceleration
hereunder, even if the conditions set forth herein are met.

from acting) upon the instructions of the Requisite Lenders, and such
instructions shall be binding upon all Lenders and each Issuer; provided,
however, that the Administrative Agent shall not be required to take any action
that (i) the Administrative Agent in good faith believes could expose it to
personal liability unless the Administrative Agent receives an indemnification
satisfactory to it from the Lenders and the Issuers with respect to such action
or (ii) is contrary to this Agreement or applicable Requirements of Law. The

Agent agrees to give to each Lender and each Issuer prompt notice of each notice
given to it by any Loan Party pursuant to the terms of this Agreement or the
other Loan Documents.

            (c) No Fiduciary Relationship. In performing its functions and
duties hereunder and under the other Loan Documents, the Administrative Agent is
acting solely on behalf of the Lenders and the Issuers and its duties are
entirely administrative in nature. The Administrative Agent does not assume (and
shall not be deemed to have assumed) any obligation other than as expressly set
forth herein and in the other Loan Documents or any other relationship as the
agent, fiduciary or trustee of or for any Lender, Issuer or holder of any other
Obligation. The Administrative Agent may perform any of its duties under any
Loan Document by or through its agents or employees.

            (d) Duties of Certain Agents. Notwithstanding anything to the
contrary contained in this Agreement, each of the Documentation Agents and
Syndication Agents is a Lender designated as "Documentation Agent" or
"Syndication Agent", as the case may be, for title purposes only and in such
capacity shall have no obligations or duties whatsoever under this Agreement or
any other Loan Document to any Loan Party, any Lender or any Issuer and shall
have no rights separate from its rights as a Lender except as expressly provided
in this Agreement.

            (e) Duties of the Arranger and Co-Arranger. Notwithstanding anything
to the contrary contained in this Agreement, each of the Arranger and the
Co-Arranger are designated as such for title purposes only and in such capacity
shall have no obligations or duties whatsoever under this Agreement or any other
Loan Document to any Loan Party, any Lender or any Issuer and shall have no
rights except as expressly provided for in the Agreement or the other Loan
Documents.

            Section 10.2 Administrative Agent's Reliance, Etc.

            None of the Administrative Agent, any of its Affiliates or any of
their respective directors, officers, agents or employees shall be liable for
any action taken or omitted to be taken by it, him, her or them under or in
connection with this Agreement or the other Loan Documents, except for its, his,
her or their own gross negligence or willful misconduct. Without limiting the
foregoing, the Administrative Agent (a) may treat the payee of any Note as its
holder until such Note has been assigned in accordance with Section 11.2
(Assignments and Participations), (b) may rely on the Register to the extent set
forth in Section 11.2(c) (Assignments and Participations), (c) may consult with
legal counsel (including counsel to the Borrower or any other Loan Party),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts, (d) makes no
warranty or representation to any Lender or Issuer and shall not be responsible
to any Lender or Issuer for any statements, warranties or representations made
by or on behalf of the Borrower or any of its Subsidiaries in, or in connection
with, this Agreement or any of the other Loan Document, (e) shall not have any
duty to ascertain or to inquire either as to (i) the performance or observance
of any term, covenant or condition of this Agreement or any other Loan Document,
(ii) the financial condition of any Loan Party or (iii) the existence or
possible existence of any Default or Event of Default, (f) shall not be
responsible to any Lender or Issuer for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the attachment,
perfection or priority of any Lien created or purported to be created under or
in connection with, this Agreement or any other Loan Document or any other
instrument or document furnished pursuant hereto or thereto and (g) shall

Document by acting upon any notice, consent, certificate or other instrument or
writing (which writing may be a telecopy or electronic mail) or any telephone
message believed by it to be genuine and signed or sent by the proper party or
parties.

            Section 10.3 The Agents as Lenders

            With respect to its Ratable Portion, each Agent shall have and may
exercise the same rights and powers hereunder and is subject to the same
obligations and liabilities as and to the extent set forth herein for any other
Lender. The terms "Lenders," "Requisite Lenders," and any similar term shall,
unless the context clearly otherwise indicates, include, without limitation,
each Agent in its individual capacity as a Lender or, as the case may be, as one
of the Requisite Lenders. Each Agent and each of their respective Affiliates may
accept deposits from, lend money to and generally engage in any kind of banking,
trust or other business with, any Loan Party as if such Agent or such Affiliate
were not acting as Agent.

            Section 10.4 Lender Credit Decision

            Each Lender and each Issuer acknowledges that it shall,
independently and without reliance upon the Agents or any other Lender conduct
its own independent investigation of the financial condition and affairs of the
Borrower, its Material Subsidiaries and each other Loan Party in connection with
the making and continuance of the Loans and with the Issuance of the Letters of
Credit. Each Lender and each Issuer also acknowledges that it shall,
independently and without reliance upon any Agent or any other Lender and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and other Loan Documents.

            Section 10.5 Indemnification

            Each Lender agrees to indemnify the Administrative Agent, each of
its Affiliates, and each of their respective directors, officers, employees,
agents and advisors (to the extent not reimbursed by the Borrower), from and
against such Lender's aggregate Ratable Portion of any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses and disbursements (including fees and disbursements of legal counsel)
of any kind or nature whatsoever that may be imposed on, incurred by, or
asserted against, the Administrative Agent, any of its Affiliates or any of
their respective directors, officers, employees, agents and advisors in any way
relating to or arising out of this Agreement or the other Loan Documents or any
action taken or omitted by the Administrative Agent under this Agreement or the
other Loan Documents; provided, however, that no Lender shall be liable to the
Administrative Agent, any of its Affiliates or any of their respective
directors, officers, employees, agents and advisors for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Administrative Agent's or
such Affiliate's gross negligence or willful misconduct. Without limiting the
foregoing, each Lender agrees to reimburse the Administrative Agent promptly
upon demand for its ratable share of any out-of-pocket expenses (including fees
and disbursements of legal counsel) incurred by the Administrative Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, Legal
Proceedings or otherwise) of, or legal advice in respect of its rights or
responsibilities under, this Agreement or the other Loan Documents, to the
extent that the Administrative Agent is not reimbursed for such expenses by the
Borrower or another Loan Party.

            Section 10.6 Successor Administrative Agent

            The Administrative Agent may resign at any time by giving written
notice thereof to the Lenders and the Borrower. Upon any such resignation, the
Requisite Lenders shall have the right to appoint a successor Administrative
Agent. If no successor Administrative Agent shall have been so appointed by the
Requisite Lenders, and shall have accepted such appointment, within thirty (30)
days after the retiring Administrative Agent's giving of notice of resignation,
then the retiring Administrative Agent may, on behalf of the Lenders, appoint a
successor Administrative Agent selected from among the Lenders. In either case,
such appointment shall be subject to the prior written approval of the Borrower
(which approval may not be unreasonably withheld and shall not be required upon
the occurrence and during the continuance of an Event of Default). Upon the
acceptance of any appointment as Administrative Agent by a successor
Administrative Agent, such successor Administrative Agent shall succeed to, and
become vested with, all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations under this Agreement and the other
Loan Documents. Prior to any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the retiring Administrative Agent shall take
such action as may be necessary to assign to the successor Administrative Agent
its rights as Administrative Agent under the Loan Documents. After such
resignation, the retiring Administrative Agent shall continue to have the
benefit of this Article X as to any actions taken, or omitted to be taken, by it
while it was Administrative Agent under this Agreement and the other Loan
Documents.

            Section 10.7 Concerning the Collateral and the Collateral Documents

            (a) Authorization to Enter into Collateral Documents. Each Lender
and each Issuer agrees that any action taken by the Administrative Agent or the
Requisite Lenders in accordance with the provisions hereof or of the other Loan
Documents, and the exercise by the Administrative Agent or the Requisite Lenders
of the powers set forth herein or therein, together with such other powers as
are reasonably incidental thereto, shall be authorized and binding upon all of
the Lenders, Issuers and other Secured Parties. Without limiting the generality
of the foregoing, the Administrative Agent shall have the sole and exclusive
right and authority to (i) act as the disbursing and collecting agent for the
Lenders and the Issuers with respect to all payments and collections arising in
connection herewith and with the Collateral Documents, (ii) execute and deliver
each Collateral Document and accept delivery of each such agreement delivered by
the Borrower or any of its Material Subsidiaries, (iii) act as collateral agent
for the Lenders, the Issuers and the other Secured Parties for purposes of the
perfection of all security interests and Liens created by such agreements and
all other purposes stated therein, provided, however, that the Administrative
Agent hereby appoints, authorizes and directs each Lender and Issuer to act as
collateral sub-agent for the Administrative Agent, the Lenders and the Issuers
for purposes of the perfection of all security interests and Liens with respect
to the Borrower's and its Material Subsidiaries' respective deposit accounts
maintained with, and cash and Cash Equivalents held by, such Lender or such
Issuer, (iv) manage, supervise and otherwise deal with the Collateral, (v) take
such action as is necessary or desirable to maintain the perfection and priority
of the security interests and Liens created or purported to be created by the
Collateral Documents and (vi) except as otherwise specifically restricted by the
terms hereof or of any other Loan Document, exercise all remedies given to the
Administrative Agent, the Lenders, the Issuers and the other Secured Parties
with respect to the Collateral under the Loan Documents relating thereto,
applicable Requirement of Law or otherwise.

            (b) Release of Liens. Each of the Lenders and the Issuers hereby
directs, in accordance with the terms hereof, the Administrative Agent to
release (or, in the case of clause (ii) below, release or subordinate) any Lien
held by the Administrative Agent for the benefit of the Lenders and the Issuers:

                  (i) against all of the Collateral, upon termination of the
      Commitments and payment and satisfaction in full of all Loans,
      Reimbursement Obligations and all other Obligations that the
      Administrative Agent has been notified in writing are then due and payable
      (and, in respect of contingent Letter of Credit Obligations, with respect
      to which cash collateral has been deposited or a back-up letter of credit
      has been issued, in either case on terms satisfactory to the
      Administrative Agent and the applicable Issuers);

                  (ii) against any part of the Collateral sold or disposed of by
      a Loan Party if such sale or disposition is permitted by this Agreement;

                  (iii) against any assets that are subject to a Lien permitted
      by Section 8.2(d) or (e) (Liens, Etc.); and

                  (iv) as expressly provided for in any Collateral Document.

Each of the Lenders and the Issuers hereby directs the Administrative Agent to
execute and deliver or file such termination and partial release statements and
do such other things as are necessary to release Liens to be released pursuant
to this Section 10.7 promptly upon the effectiveness of any such release.

            Section 10.8 Collateral Matters Relating to Related Obligations

            The benefit of the Loan Documents and of the provisions of this
Agreement relating to the Collateral shall extend to and be available in respect
of any Secured Obligation arising under any Hedging Contract or that is
otherwise owed to Persons other than the Administrative Agent, the Lenders and
the Issuers (collectively, "Related Obligations") solely on the condition and
understanding, as among the Administrative Agent and all Secured Parties, that
(i) the Related Obligations shall be entitled to the benefit of the Loan
Documents and the Collateral to the extent expressly set forth in this Agreement
and the other Loan Documents and to such extent the Administrative Agent shall
hold, and have the right and power to act with respect to, the Guaranty and the
Collateral on behalf of and as agent for the holders of the Related Obligations,
but the Administrative Agent is otherwise acting solely as agent for the Lenders
and the Issuers and shall have no fiduciary duty, duty of loyalty, duty of care,
duty of disclosure or other obligation whatsoever to any holder of Related
Obligations, (ii) all matters, acts and omissions relating in any manner to the
Guaranty, the Collateral, or the omission, creation, perfection, priority,
abandonment or release of any Lien, shall be governed solely by the provisions
of this Agreement and the other Loan Documents and no separate Lien, right,
power or remedy shall arise or exist in favor of any Secured Party under any
separate instrument or agreement or in respect of any Related Obligation, (iii)
each Secured Party shall be bound by all actions taken or omitted, in accordance
with the provisions of this Agreement and the other Loan Documents, by the
Administrative Agent and the Requisite Lenders, each of whom shall be entitled
to act at its sole discretion and exclusively in its own interest given its own
Commitments and its own interest in the Loans, Letter of Credit Obligations and
other Obligations to it arising under this Agreement or the other Loan
Documents, without any duty or liability to any other

            Section 11.1 Amendments, Waivers, Etc.

            (a) No amendment or waiver of any provision of this Agreement or any
other Loan Document (other than, prior to the Syndication Completion Date, any
amendment or supplement to Schedule I (Commitments) expressly permitted
hereunder) nor consent to any departure by any Loan Party therefrom shall in any
event be effective unless the same shall be in writing and signed by the
Requisite Lenders (or by the Administrative Agent as specifically empowered
hereunder or with the consent of the Requisite Lenders) and, in the case of any
amendment, by the Borrower, and then any such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no amendment, waiver or consent shall, unless in
writing and signed:

                  (i) by the Super-Majority Lenders, amend the definition of
      "Minimum Available Credit" to lower the amount thereof or amend the
      definition of "Borrowing Base";

                  (ii) by each Lender affected thereby, do any of the following:

      (A) waive any condition specified in Section 3.1 (Conditions Precedent to

      therein) or 3.2(b) (Conditions Precedent to Each Loan and Letter of
      Credit), except with respect to a condition based upon another provision
      hereof, the amendment of which requires only the consent of the Requisite
      Lenders, in which case only such consent shall be required to waive such
      condition;

      (B) increase the Commitments of such Lender or subject such Lender to any
      additional obligation;

      (C) extend the scheduled final maturity of any Loan, or waive, reduce or

      (E) other than in accordance with the Pricing Grid, reduce the rate of

      Notes, or release Pellet, NSFC, ProCoil, NSH or any other Material
      Subsidiary from its respective obligations under the Guaranty, except in
      connection with any sale or other disposition of such Guarantor permitted
      by this Agreement (or permitted pursuant to a waiver or consent of a
      transaction otherwise prohibited by this Agreement) or as expressly
      permitted under the Guaranty; or

      (B) amend Section 5.2 (Available Credit) to reduce the amount of
      "$50,000,000" specified therein;

      (C) amend Section 10.7(b) (Concerning the Collateral and the Collateral
      Documents), this proviso, any provision requiring the consent of all
      Lenders or the definition of the term "Ratable Portion"; and

provided, further, that (A) no amendment, waiver or consent shall affect the
rights or duties of the Administrative Agent under this Agreement or the other
Loan Documents unless such amendment, waiver or consent is in writing and signed
by the Administrative Agent in addition to the Lenders otherwise required under
this Section 11.1 to take such action and (B) no amendment, waiver or consent
shall, unless in writing and signed by any Special Purpose Vehicle that has been

Purpose Vehicle hereunder.

            (b) The Administrative Agent may, but shall have no obligation to,
with the written concurrence of any Lender, execute amendments, modifications,
waivers or consents on behalf of such Lender. Any waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
it was given. No notice to or demand on the Borrower in any case shall entitle
the Borrower to any other or further notice or demand in similar or other
circumstances.

            (c) If, in connection with any proposed amendment, modification,
waiver or termination (a "Proposed Change") requiring the consent of all
affected Lenders, the consent of Requisite Lenders is obtained but the consent
of other Lenders whose consent is required is not obtained (any such Lender
whose consent is not obtained as described in this Section 11.1 being referred
to as a "Non-Consenting Lender"), then, so long as the Lender acting as the
Administrative Agent is not a Non-Consenting Lender, at the Borrower's request,
the Administrative Agent or an Eligible Assignee acceptable to the
Administrative Agent shall have the right with the Administrative Agent's
consent and in the Administrative Agent's sole discretion (but shall have no
obligation) to purchase from such Non-Consenting Lender, and such Non-Consenting
Lender agrees that it shall, upon the Administrative Agent's request, sell and

assign to the Lender acting as the Administrative Agent or such Eligible
Assignee (in either case without recourse or warranty, all of the Commitments,
and Outstandings of such Non-Consenting Lender for an amount equal to the
principal balance of all Loans held by the Non-Consenting Lender plus all
accrued interest and fees with respect thereto through the date of sale less
unamortized upfront and closing fees, such purchase and sale to be consummated
pursuant to an executed Assignment and Acceptance.

            Section 11.2 Assignments and Participations

            (a) Right to Assign. Each Lender may sell, transfer, negotiate or
assign to one or more Eligible Assignees all or a portion of its rights and
obligations hereunder (including all of its rights and obligations with respect
to the Revolving Loans, the Swing Loans and the Letters of Credit); provided,
however, that (i) if any such assignment shall be of the assigning Lender's
Outstandings and Commitment, such assignment shall cover the same percentage of
such Lender's Outstandings and Commitment, (ii) the aggregate amount being
assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event (if
less than the Assignor's entire interest) be less than five million Dollars
($5,000,000) or an integral multiple of one million Dollars ($1,000,000) in
excess thereof; and (iii) if such Eligible Assignee is not, prior to the date of
such assignment, a Lender or an Affiliate or Approved Fund of a Lender, such
assignment shall be subject to the prior consent of the Administrative Agent and
the Borrower (which consent shall not be unreasonably withheld or delayed);
provided, however, that prior to the Syndication Completion Date, SSBI may in
its sole discretion determine to assign a lesser amount or assign to any Person;
and provided, further, that, notwithstanding any other provision of this Section
11.2, the consent of the Borrower shall not be required for any assignment
occurring either prior to the Syndication Completion Date or when any Event of
Default shall have occurred and be continuing.

            (b) Effect of Assignment. The parties to each assignment shall
execute and deliver to the Administrative Agent, for its acceptance and
recording, an Assignment and Acceptance, together with any Note (if the
assigning Lender's Loans are evidenced by a Note) subject to such assignment.
Upon such execution, delivery, acceptance and recording and the receipt by the
Administrative Agent from the assignee of an assignment fee in the amount of
three thousand five hundred Dollars ($3,500) from and after the effective date
specified in such Assignment and Acceptance, (i) the assignee thereunder shall
become a party hereto and, to the extent that rights and obligations under the
Loan Documents have been assigned to such assignee pursuant to such Assignment
and Acceptance, have the rights and obligations of a Lender and, if such Lender
were an Issuer, of such Issuer hereunder and thereunder, and (ii) the assignor
thereunder shall, to the extent that rights and obligations under this Agreement
have been assigned by it pursuant to such Assignment and Acceptance, relinquish
its rights (except those that survive the payment in full of the Obligations)
and be released from its obligations under the Loan Documents, other than those
relating to events or circumstances occurring prior to such assignment (and, in
the case of an Assignment and Acceptance covering all or the remaining portion
of an assigning Lender's rights and obligations under the Loan Documents, such
Lender shall cease to be a party hereto).

            (c) Maintenance of Records. The Administrative Agent shall maintain
at its address referred to in Section 11.12 (Notices, Etc.) a copy of each
Assignment and Acceptance delivered to and accepted by it and a register for the
recording of the names and addresses of the Lenders and the Commitments of and
principal amount of the Loans and Letter of Credit Obligations owing to each
Lender from time to time (the "Register"). Any assignment pursuant

to this Section 11.2 shall not be effective until such assignment is recorded in
the Register. The entries in the Register shall be conclusive and binding for
all purposes, absent manifest error, and the Loan Parties, the Administrative
Agent and the Lenders may treat each Person whose name is recorded in the
Register as a Lender for all purposes of this Agreement. The Register shall be
available for inspection by the Borrower, the Administrative Agent or any Lender
at any reasonable time and from time to time upon reasonable prior notice.

            (d) Tax Effect. Notwithstanding anything to the contrary contained
in the previous paragraph of this Section 11.2, the Loans (including the Notes
evidencing such Loans) are registered obligations and the right, title, and
interest of the Lenders and their assignees in and to such Loans shall be
transferable only upon notation of such transfer in the Register. A Note shall
only evidence the Lender's or an assignee's right title and interest in and to
the related Loan, and in no event is any such Note to be considered a bearer
instrument or obligation. This Section 11.2 shall be construed so that the Loans
are at all times maintained in "registered form" within the meaning of Sections
163(f), 871(h)(2) and 881(c)(2) of the Internal Revenue Code and any related
regulations (or any successor provisions of the Internal Revenue Code or such
regulations). Solely for purposes of this and for tax purposes only, the
Administrative Agent shall act as the Borrower's agent for purposes of
maintaining such notations of transfer in the Register.

            (e) Procedure for Assignment. Upon its receipt of an Assignment and
Acceptance executed by an assigning Lender and an assignee, the Administrative
Agent shall, if such Assignment and Acceptance has been completed, (i) accept
such Assignment and Acceptance, (ii) record the information contained therein in
the Register and (iii) give prompt notice thereof to the Borrower. Within five
(5) Business Days after its receipt of such notice, the Borrower, at its own
expense, shall, if requested by such assignee, execute and deliver to the
Administrative Agent, new Notes to the order of such assignee in an amount equal
to the Commitments assumed by it pursuant to such Assignment and Acceptance and,
if the assigning Lender has surrendered any Note for exchange in connection with
the assignment and has retained Commitments hereunder, new Notes to the order of
the assigning Lender in an amount equal to the Commitments retained by it
hereunder. Such new Notes shall be dated the same date as the surrendered Notes
and be in substantially the form of Exhibit A (Form of Revolving Credit Note).

            (f) Assignment to Special Purpose Vehicles, to the Federal Reserve
Bank or to a Trustee. In addition to the other assignment rights provided in
this Section 11.2, each Lender may (i) grant to a Special Purpose Vehicle the
option to make all or any part of any Loan that such Lender would otherwise be
required to make hereunder and the exercise of such option by any such Special
Purpose Vehicle and the making of Loans pursuant thereto shall satisfy (once and
to the extent that such Loans are made) the obligation of such Lender to make
such Loans thereunder, provided, however, that nothing herein shall constitute a
commitment or an offer to commit by such a Special Purpose Vehicle to make Loans
hereunder and no such Special Purpose Vehicle shall be liable for any indemnity
or other Obligation (other than the making of Loans for which such Special
Purpose Vehicle shall have exercised an option, and then only in accordance with
the relevant option agreement), and (ii) assign, as collateral or otherwise, any
of its rights under this Agreement (including rights to payments of principal or
interest on the Loans) to (x) any Federal Reserve Bank pursuant to Regulation A
of the Federal Reserve Board without notice to or consent of the Borrower or the
Administrative Agent, (y) any trustee for the benefit of the holders of such
Lender's Securities and (z) to any Special Purpose Vehicle to which such

                                                                CREDIT AGREEMENT

Lender has granted an option pursuant to clause (i) above; and provided,
further, that no such assignment or grant shall release such Lender from any of
its obligations hereunder except as expressly provided in clause (i) above. The
parties hereto acknowledge and agree that, prior to the date that is one year
and one day after the payment in full in cash of all outstanding commercial
paper or other senior debt of any such Special Purpose Vehicle, it will not
institute against, or join any other Person in instituting against, any Special
Purpose Vehicle that has been granted an option pursuant to this clause (f) any
bankruptcy, reorganization, insolvency or liquidation proceeding (such agreement
shall survive payment in full of the Obligations).

            (g) Sale of Participations. Each Lender may sell participations to
one or more banks or other Persons in or to all or a portion of its rights and
obligations under the Loan Documents (including all its rights and obligations
with respect to the Revolving Loans and Letters of Credit); provided, however,
that such sale shall be effective only upon receipt by the Administrative Agent
of a notice of such sale in form and substance satisfactory to the
Administrative Agent. The terms of such participation shall not, in any event,
require the participant's consent to any amendments, waivers or other
modifications of any provision of any Loan Documents or the consent to any
departure by any Loan Party therefrom or to the exercising or refraining from
exercising any powers or rights which such Lender may have under or in respect
of the Loan Documents (including the right to enforce the obligations of the
Loan Parties), except if any such amendment, waiver or other modification or
consent would (i) reduce the amount, or postpone any date fixed for, any amount
(whether of principal, interest or fees) payable to such participant under the
Loan Documents, to which such participant would otherwise be entitled under such
participation or (ii) result in the release of all or substantially all of the
Collateral other than in accordance with the Collateral Documents. In the event
of the sale of any participation by any Lender, (A) such Lender's obligations
under the Loan Documents shall remain unchanged, (B) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (C) such Lender shall remain the holder of such Obligations for all
purposes of this Agreement, (D) such Lender shall disclose to the Borrower the
identity of each bank or other entity purchasing a participation within a
reasonable time after the sale and purchase of such participation and (E) the
Borrower, the Administrative Agent and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Each participant shall be entitled to the
benefits of Sections 2.15 (Capital Adequacy), 2.16 (Taxes) and 2.14(d) (Special
Provisions Governing Eurodollar Rate Loans) as if it were a Lender; provided,
however, that anything herein to the contrary notwithstanding, the Borrower
shall not, at any time, be obligated to make under Section 2.15 (Capital
Adequacy), 2.16 (Taxes) or 2.14(d) (Special Provisions Governing Eurodollar Rate
Loans) to the participants in the rights and obligations of any Lender (together
with such Lender) any payment in excess of the amount the Borrower would have
been obligated to pay to such Lender in respect of such interest had such
participation not been sold.

            (h) Assignments by Issuers. Any Issuer may at any time assign its
rights and obligations hereunder to any Lender or any Affiliate of a Lender by
an instrument in form and substance satisfactory to the Borrower, the
Administrative Agent, such Issuer and such Lender. If any Issuer ceases to be a
Lender hereunder by virtue of any assignment made pursuant to this Section 11.2,
then, as of the effective date of such cessation, such Issuer's obligations to
Issue Letters of Credit pursuant to Section 2.4 (Letters of Credit) shall
terminate and such Issuer shall be an Issuer hereunder only with respect to
outstanding Letters of Credit issued prior to such date.

commencement, defense or intervention in any court proceeding relating in any
way to the Obligations, any Loan Party, any of the Borrower's Subsidiaries, the
Related Documents, the Existing Credit Agreement, this Agreement or any of the
other Loan Documents, (vii) the response to, and preparation for, any subpoena
or request for document production with which the Administrative Agent is served
or deposition or other proceeding in which the Administrative Agent is called to
testify, in each case, relating in any way to the Obligations, any Loan Party,
any of the Borrowers' Subsidiaries, the Related Documents, the Existing Credit
Agreement, this Agreement or any of the other Loan Documents and (viii) any
amendments, consents, waivers, assignments, restatements, or supplements to any
of the Loan Documents and the preparation, negotiation, and execution of the
same.

            (b) The Borrower further agrees to pay or reimburse the
Administrative Agent and each of the other Agents, Lenders and Issuers upon
demand for all out-of-pocket costs and expenses, including, without limitation,
reasonable attorneys' fees (including allocated costs of internal counsel and
costs of settlement), incurred by the Administrative Agent, such Agents, Lenders
or Issuers (i) in enforcing any Loan Document or Obligation or any security
therefor or exercising or enforcing any other right or remedy available by
reason of an Event of Default, (ii) in connection with any refinancing or
restructuring of the credit arrangements provided hereunder in the nature of a

or arising out of the transactions contemplated hereby or by any of the other
Loan Documents or Related Documents and (iv) in taking any other action in or
with respect to any suit or proceeding (bankruptcy or otherwise) described in
clauses (i) through (iii) above.

            Section 11.4 Indemnities

            (a) Indemnification Against Third-Party Claims. The Borrower agrees
to indemnify and hold harmless the Administrative Agent, the Arranger, each
Agent, the Co-Arranger, each Lender and each Issuer and each of their respective
Affiliates, and each of the directors, officers, employees, agents,
representative, attorneys, consultants and advisors of or to any of the
foregoing (including those retained in connection with the satisfaction or
attempted satisfaction of any of the conditions set forth in Article III
(Conditions Precedent to the Effectiveness of this Agreement and to Loans and
Letters of Credit)) (each such Person being an "Indemnitee") from and against
any and all claims, damages, liabilities, obligations, losses, penalties,
actions, judgments, suits, costs, disbursements and expenses of any kind or
nature (including fees and disbursements of counsel to any such Indemnitee) that
may be imposed on, incurred by or asserted against any such Indemnitee in
connection with or arising out of any investigation, litigation or proceeding,
whether or not any such Indemnitee is a party thereto, whether direct, indirect,
or consequential and whether based on any federal, state or local law or other
statutory regulation, securities or commercial law or regulation, or under
common law or in equity, or on contract, tort or otherwise, in any manner
relating to or arising out of the Existing Credit Agreement, this Agreement, any
other Loan Document, any Obligation, any Letter of Credit, any Related Document,
or any act, event or transaction related or attendant to any thereof, or the use
or intended use of the proceeds of the Loans or Letters of Credit or in
connection with any investigation of any potential matter covered hereby
(collectively, the "Indemnified Matters"); provided, however, that the Borrower
shall not have any obligation under this Section 11.4 to an Indemnitee with
respect to any Indemnified Matter caused by or resulting from the gross
negligence or willful misconduct of that Indemnitee, as determined by a court of
competent jurisdiction in a final non-appealable judgment or order. Without
limiting the foregoing, Indemnified Matters include (i) all Environmental
Liabilities and Costs arising from or connected with the past, present or future
operations of the Borrower or any of its Subsidiaries involving any property
subject to a Collateral Document, or damage to real or personal property or
natural resources or harm or injury alleged to have resulted from any Release of
Contaminants on, upon or into such property or any contiguous real estate; (ii)
any costs or liabilities incurred in connection with any Remedial Action
concerning any Borrower or any of its Subsidiaries; (iii) any costs or
liabilities incurred in connection with any Environmental Lien; (iv) any costs
or liabilities incurred in connection with any other matter under any
Environmental Law, including the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, 49 U.S.C. ss.ss. 9601 et seq. and
applicable state property transfer laws, whether, with respect to any of such
matters, such Indemnitee is a mortgagee pursuant to any leasehold mortgage, a
mortgagee in possession, the successor in interest to the Borrower or any of its
Subsidiaries, or the owner, lessee or operator of any property of the Borrower
or any of its Subsidiaries by virtue of foreclosure, except, with respect to
those matters referred to in clauses (i), (ii), (iii) and (iv) above, to the
extent (A) incurred following foreclosure by the Administrative Agent, any other
Agent, any Lender or any Issuer, or the Administrative Agent, any other Agent,
any Lender or any Issuer having become the successor in interest to the Borrower
or any of its Subsidiaries and (B) attributable solely to acts of the
Administrative Agent, such other Agent, such Lender or such Issuer or any agent
on behalf of the Administrative Agent, such other Agent, such Lender or such
Issuer.

            (b) Reimbursement of Brokerage Fees. The Borrower shall indemnify
the Administrative Agent, the Arranger, each other Agent, the Co-Arranger, each
Lender and each Issuer for, and hold the Administrative Agent, the Arranger,
each other Agent, the Co-Arranger,

each Lender and each Issuer harmless from and against, any and all claims for
brokerage commissions, fees and other compensation made against the
Administrative Agent, the Arranger, each other Agent, the Co-Arranger, any
Lender or any Issuer for any broker, finder or consultant with respect to any
agreement, arrangement or understanding made by or on behalf of any Loan Party
or any of its Subsidiaries in connection with the transactions contemplated by
the Existing Credit Agreement or this Agreement.

            (c) Notification of the Borrower. The Administrative Agent, the
Arranger, each other Agent, the Co-Arranger, each Lender and each Issuer agree
that in the event that any such investigation, litigation or proceeding set
forth in clause (b) above is asserted or threatened in writing or instituted
against it or any other Indemnitee, or any Remedial Action is requested of it or
any of its officers, directors, agents and employees, for which any Indemnitee
may desire indemnity or defense hereunder, such Indemnitee shall promptly notify
the Borrower in writing.

            (d) Defense of Proceedings. The Borrower, at the request of any
Indemnitee, shall have the obligation to defend against such investigation,
litigation or proceeding or requested Remedial Action and the Borrower, in any
event, may participate in the defense thereof with legal counsel of the
Borrower's choice. In the event that such Indemnitee requests the Borrower to
defend against such investigation, litigation or proceeding or requested
Remedial Action, the Borrower shall promptly do so and such Indemnitee shall
have the right to have legal counsel of its choice participate in such defense.
No action taken by legal counsel chosen by such Indemnitee in defending against
any such investigation, litigation or proceeding or requested Remedial Action,
shall vitiate or in any way impair the Borrower's obligation and duty hereunder
to indemnify and hold harmless such Indemnitee.

            (e) Survival. The Borrower agrees that any indemnification or other
protection provided to any Indemnitee pursuant to this Agreement (including
pursuant to this Section 11.4) or any other Loan Document shall (i) survive
payment in full of the Obligations and (ii) inure to the benefit of any Person
who was at any time an Indemnitee under this Agreement or any other Loan
Document.

            Section 11.5 Limitation of Liability

            The Borrower agrees that no Indemnitee shall have any liability
(whether direct or indirect, in contract, tort or otherwise) to any Loan Party
or any of their respective Subsidiaries or any of their respective equity
holders or creditors for or in connection with the transactions contemplated
hereby and in the other Loan Documents and Related Documents, except for direct
damages (as opposed to special, indirect, consequential or punitive damages
(including, without limitation, any loss of profits, business or anticipated
savings)) determined in a final non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnitee's gross negligence or willful
misconduct. The Borrower hereby waives, releases and agrees (for itself and on
behalf of its Subsidiaries) not to sue upon any such claim for any special,
indirect, consequential or punitive damages, whether or not accrued and whether
or not known or suspected to exist in its favor.

            Section 11.6 Right of Set-off

            Upon the occurrence and during the continuance of any Event of
Default, each Lender and each Affiliate thereof is hereby authorized at any time
and from time to time, to the fullest extent permitted by Requirements of 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 indebtedness at any time owing by such Lender or its Affiliates to or for
the credit or the account of the Borrower against any and all of the Obligations
now or hereafter existing whether or not such Lender shall have made any demand
under this Agreement or any other Loan Document and although such Obligations
may be unmatured. Each Lender agrees promptly to notify the Borrower after any
such set-off and application made by such Lender or its Affiliates; provided,
however, that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of each Lender under this Section 11.6
are in addition to the other rights and remedies (including other rights of
set-off) that such Lender may have.

            Section 11.7 Sharing of Payments, Etc.

            (a) Purchase of Participations. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off or otherwise) of the Loans owed to it, an interest thereon, fees in
respect thereof or amounts due pursuant to Sections 11.3 (Costs and Expenses)
and 11.4 (Indemnities) (other than pursuant to Section 2.14 (Special Provisions
Governing Eurodollar Rate Loans), 2.15 (Capital Adequacy) or 2.16 (Taxes)) in
excess of its Ratable Portion of all payments of such Obligations obtained by
all the Lenders on account of such Obligations, such Lender (a "Purchasing
Lender") shall forthwith purchase from the other Lenders (each, a "Selling
Lender") such participations in their Loans or other Obligations as shall be
necessary to cause such Purchasing Lender to share the excess payment ratably
with each of them.

            (b) Payment Refunded. If all or any portion of any payment received
by a Purchasing Lender is thereafter recovered from such Purchasing Lender, such
purchase from each Selling Lender shall be rescinded and such Selling Lender
shall repay to the Purchasing Lender the purchase price to the extent of such
recovery together with an amount equal to such Selling Lender's ratable share
(according to the proportion of (i) the amount of such Selling Lender's required
repayment to (ii) the total amount so recovered from the Purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered.

            (c) Rights of Purchasing Lender. The Borrower agrees that any
Purchasing Lender so purchasing a participation from a Selling Lender pursuant
to this Section 11.7 may, to the fullest extent permitted by Requirements of
Law, exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Borrower in the amount of such participation.

            Section 11.8 Independence of Representations and Warranties

            The parties hereto intend that each representation, warranty and
covenant contained herein shall have independent significance. If the Borrower
has breached any representation, warranty or covenant contained herein in any
respect, the fact that there exists another representation, warranty or covenant
relating to the same subject matter (regardless of the relative levels of
specificity) that the Borrower has not breached shall not detract from or
mitigate the fact that such party is in breach of the first representation,
warranty or covenant.

Process

            (a) Any legal action or proceeding with respect to this Agreement or
any other Loan Document may be brought in the courts of the State of New York or
of the United States of America for the Southern District of New York, and, by
execution and delivery of this Agreement, the Borrower hereby accepts for itself
and in respect of its property, generally and unconditionally, the jurisdiction
of the aforesaid courts. The parties hereto hereby irrevocably waive any
objection, including any objection to the laying of venue or based on the
grounds of forum non conveniens, that any of them may now or hereafter have to

            (b) The Borrower hereby irrevocably consents to the service of any
and all legal process, summons, notices and documents in any suit, action or
proceeding brought in the United States of America arising out of or in
connection with this Agreement or any of the other Loan Documents by the mailing
(by registered or certified mail, postage prepaid) or delivering of a copy of
such process to the Borrower at its address specified in Section 11.12 (Notices,
Etc.). The Borrower agrees that a final 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.]

            (c) Nothing contained in this Section 11.10 shall affect the right
of the Administrative Agent, any other Agent or any Lender or Issuer to serve
process in any other manner permitted by law or commence legal proceedings or
otherwise proceed against the Borrower or any other Loan Party in any other
jurisdiction.

            (d) If for the purposes of obtaining judgment in any court it is
necessary to convert a sum due hereunder in Dollars into another currency, the
parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures the Administrative Agent could purchase Dollars with such
other currency at the spot rate of exchange quoted by the Administrative Agent
at 11:00 a.m. (New York time) on the Business Day preceding that on which final
judgment is given, for the purchase of Dollars, for delivery two Business Days

Intermediaries as it in its sole discretion shall determine. Each such account
shall be in the name of the Administrative Agent (but may also have words
referring to the Borrower and the account's purpose). The Borrower agrees that
each such account shall be under the sole dominion and control of the
Administrative Agent. The Administrative Agent shall be the entitlement holder
with respect to each such Securities Account and the only Person authorized to
give entitlement orders with respect thereto. Without limiting the foregoing,
funds on deposit in any Cash Collateral Account may be invested in Cash
Equivalents at the direction of the Administrative Agent and, except during the
continuance of an Event of Default, the Administrative Agent agrees with the
Borrower to issue entitlement orders for such investments in Cash Equivalents as
requested by the Borrower; provided, however, that the Administrative Agent
shall not have any responsibility for, or bear any risk of loss of, any such
investment or income thereon. Neither the Borrower nor any other Loan Party or
Person claiming on behalf of or through the Borrower or any other Loan Party
shall have any right to demand payment of any of the funds held in any Cash
Collateral Account at any time prior to the termination of all outstanding
Letters of Credit and the payment in full of all then outstanding monetary
Obligations then due and payable. The Administrative Agent shall apply all funds
on deposit in any Cash Collateral Account as provided in the Credit Agreement
and, except during the continuance of an Event of Default, agrees to cause any
funds remaining on deposit therein after all Obligations then due and payable
have been satisfied and all Letter of Credit Obligations have been cash
collateralized at 105% to be paid at the written direction of the Borrower.

            ARTICLE III. REPRESENTATIONS AND WARRANTIES

            To induce the Lenders, the Issuers and the Administrative Agent to
enter into the Credit Agreement, each Grantor hereby represents and warrants to
the Administrative Agent, the Lenders, the Issuers and the other Secured Parties
that:

            Section 3.1 Title; No Other Liens. Except for the Lien granted to
the Administrative Agent pursuant to this Security Agreement and the other Liens
permitted to exist on the Collateral under the Credit Agreement, such Grantor is
the record and beneficial owner of the Pledged Collateral pledged by it
hereunder constituting Instruments or certificated securities, is the
entitlement holder of all such Pledged Collateral constituting Investment
Property held in a Securities Account and has rights in or the power to transfer
each other item of Collateral in which a Lien is granted by it hereunder, free
and clear of any and all Liens.

            Section 3.2 Perfection and Priority. The security interest granted
pursuant to this Security Agreement will constitute a valid and continuing
perfected security interest in favor of the Administrative Agent in the
Collateral for which perfection is governed by the UCC or filing with the United
States Copyright Office upon (i) the completion of the filings and other actions
specified on Schedule 3 (which, in the case of all filings and other documents
referred to on such schedule, have been delivered to the Administrative Agent in
completed and duly executed form), (ii) the delivery to the Administrative Agent
of all Collateral consisting of Instruments and certificated securities, in each
case properly endorsed for transfer to the Administrative Agent or in blank, the
execution of Control Account Agreements with respect to Investment Property not
in certificated form, (iii) the execution of Deposit Account Control Agreements
with respect to all Deposit Accounts (other than the Cash Collateral Account),
and (iv) all appropriate filings having been made with the United States
Copyright Office. Such security interest will be prior to all other Liens on the
Collateral except for Customary Permitted Liens which have priority over the
Administrative Agent's Lien by operation of law or otherwise as permitted under
the Credit Agreement.

or other equity securities of any nature or to issue any other securities

Collateral, such Grantor agrees to be bound by the terms of this Security
Agreement relating to the Pledged Collateral issued by it and will comply with
such terms insofar as such terms are applicable to it. In the case of each
Grantor which is a partner in a Partnership, such Grantor hereby consents to the
extent required by the applicable Partnership Agreement to the pledge by each
other Grantor, pursuant to the terms hereof, of the Pledged Partnership
Interests in such Partnership and to the transfer of such Pledged Partnership
Interests to the Administrative Agent or its nominee and to the substitution of
the Administrative Agent or its nominee as a substituted partner in such

                                       12

<PAGE>

Partnership with all the rights, powers and duties of a general partner or a
limited partner, as the case may be. In the case of each Grantor which is a
member of an LLC, such Grantor hereby consents to the extent required by the
applicable LLC Agreement to the pledge by each other Grantor, pursuant to the
terms hereof, of the Pledged LLC Interests in such LLC and to the transfer of
such Pledged LLC Interests to the Administrative Agent or its nominee and to the

of the LLC with all the rights, powers and duties of a member of the LLC in
question.

            (f) Such Grantor will not agree to any amendment of an LLC Agreement
or Partnership Agreement that in any way adversely affects the perfection of the
security interest of the Administrative Agent in the Pledged Partnership
Interests or Pledged LLC Interests pledged by such Grantor hereunder, including
any amendment electing to treat the membership interest or partnership interest
of such Grantor as a security under Section 8-103 of the UCC.

            Section 4.5 Control Accounts; Approved Deposit Accounts. In the
event (i) such Grantor or any Approved Securities Intermediary or Deposit
Account Bank shall, after the date hereof, terminate an agreement with respect
to the maintenance of a Control Account or Approved Deposit Account for any
reason, (ii) the Administrative Agent shall demand such termination as a result
of the failure of an Approved Securities Intermediary or Deposit Account Bank to
comply with the terms of the applicable Control Account Agreement or Deposit
Account Control Agreement, or (iii) the Administrative Agent determines in its
sole discretion that the financial condition of an Approved Securities
Intermediary or Deposit Account Bank, as the case may be, has materially
deteriorated, such Grantor agrees to notify all of its obligors that were making
payments to such terminated Control Account or Approved Deposit Account, as the
case may be, to make all future payments to another Control Account or Approved
Deposit Account, as the case may be.

            Section 4.6 Accounts.

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

            (b) At the sole cost and expense of the relevant Grantor, the
Administrative Agent shall have the right to make test verifications of the
Accounts in any manner and through any medium that it reasonably considers
advisable, and such Grantor shall furnish all such assistance and information as
the Administrative Agent may reasonably require in connection therewith. At any
time and from time to time, upon the Administrative Agent's request and at the
expense of the relevant Grantor, such Grantor shall cause independent public
accountants or others satisfactory to the Administrative Agent to furnish to the
Administrative Agent reports showing reconciliations, aging and test
verifications of, and trial balances for, the Accounts; provided, however, that
unless a Default or Event of Default shall be continuing, the Administrative
Agent shall request no more than four such reports during any calendar year.

            Section 4.7 Delivery of Instruments and Chattel Paper. If any amount
in excess of $100,000 payable under or in connection with any of the Collateral
owned by such Grantor shall be or become evidenced by an Instrument or Chattel

immediately deliver such Instrument or Chattel Paper to the Administrative
Agent, duly indorsed in a manner satisfactory to the Administrative Agent, or,

evidenced or secured hereby are subject to the security interest of Citicorp
USA, Inc., as Administrative Agent".

            Section 4.8 Intellectual Property.

            (a) Such Grantor (either itself or through licensees) will (i)

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

            (g) Whenever such Grantor, either by itself or through any agent,
licensee or designee, shall file an application for the registration of any
Intellectual Property with the United States Patent and Trademark Office, the
United States Copyright Office or any similar office or

                                       14

            ARTICLE V. REMEDIAL PROVISIONS

            Section 5.1 Code and Other Remedies. During the continuance of an
Event of Default, the Administrative Agent may exercise, in addition to all
other rights and remedies granted to them in this Security Agreement and in any
other instrument or agreement securing, evidencing or relating to the Secured
Obligations, all rights and remedies of a secured party under the UCC or any
other applicable law. Without limiting the generality of the foregoing, the
Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon any Grantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, grant options to purchase, or otherwise dispose of and deliver
the Collateral or any part thereof (or contract to do any of the foregoing), in
one or more parcels at public or private sale or sales, at any exchange,
broker's board or office of the Administrative Agent or any Lender or elsewhere
upon such terms and conditions as it may deem advisable and at such prices as it
may deem best, for cash or on credit or for future delivery without assumption
of any credit risk. The Administrative Agent shall have the right upon any such
public sale or sales, and, to the extent permitted by law, upon any such private
sale or sales, to purchase the whole or any part of the Collateral so sold, free
of any right or equity of redemption in any Grantor, which right or equity is
hereby waived and released. Each Grantor further agrees, at the Administrative
Agent's request, to assemble the Collateral and make it available to the
Administrative Agent at places which the Administrative Agent shall reasonably
select, whether at such Grantor's premises or elsewhere. The Administrative
Agent shall apply the net proceeds of any action taken by it pursuant to this
Section 5.1, after deducting all reasonable costs and expenses of every kind
incurred in connection therewith or incidental to the care or safekeeping of any
of the Collateral or in any way relating to the Collateral or the rights of the
Administrative Agent and any other Secured Party hereunder, including reasonable
attorneys' fees and disbursements, to the payment in whole or in part of the
Secured Obligations, in such order as the Credit Agreement shall prescribe, and
only after such application and after the payment by the Administrative Agent of
any other amount required by any provision of law, need the Administrative Agent
account for the surplus, if any, to any Grantor. To the extent permitted by
applicable law, each Grantor waives all claims, damages and demands it may
acquire against the Administrative Agent or any other Secured Party arising out
of the exercise by them of any rights hereunder. If any notice of a proposed
sale or other disposition of Collateral shall be required by law, such notice
shall be deemed reasonable and proper if given at least ten (10) days before
such sale or other disposition.

            Section 5.2 Accounts and Payments in Respect of General Intangibles.

            (a) If required by the Administrative Agent at any time during the
continuance of an Event of Default, any payments of Accounts or payments in
respect of General Intangibles, when collected by any Grantor, shall be
forthwith (and, in any event, within two (2) Business

                                       16

<PAGE>

Days) deposited by such Grantor in the exact form received, duly indorsed by
such Grantor to the Administrative Agent if required, in a Cash Collateral
Account, subject to withdrawal by the Administrative Agent as provided in
Section 5.4. Until so turned over, such payments shall be held by such Grantor
in trust for the Administrative Agent, segregated from other funds of such
Grantor. Each such deposit of Proceeds of Accounts and payments in respect of
General Intangibles shall be accompanied by a report identifying in reasonable
detail the nature and source of the payments included in the deposit.

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

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

            (d) The Administrative Agent in its own name or in the name of
others may at any time during the continuance of an Event of Default communicate
with Account Debtors to verify with them to the Administrative Agent's
satisfaction the existence, amount and terms of any Accounts or amounts due
under any General Intangibles.

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

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

            Section 5.3 Pledged Collateral.

            (a) During the continuance of an Event of Default, upon notice by
the Administrative Agent to the relevant Grantor or Grantors, (i) the
Administrative Agent shall have

                                       17

<PAGE>

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

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

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

                                       18

<PAGE>

            Section 5.4 Proceeds to be Turned Over To Administrative Agent. All
Proceeds received by the Administrative Agent hereunder shall be held by the
Administrative Agent in a Cash Collateral Account. All Proceeds while held by
the Administrative Agent in a Cash Collateral Account (or by such Grantor in
trust for the Administrative Agent) shall continue to be held as collateral
security for the Secured Obligations and shall not constitute payment thereof
until applied as provided in the Credit Agreement.

            Section 5.5 Registration Rights.

            (a) If the Administrative Agent shall determine to exercise its
right to sell any or all of the Pledged Collateral pursuant to Section 5.1, and
if in the opinion of the Administrative Agent it is necessary or advisable to
have the Pledged Collateral, or any portion thereof to be registered under the
provisions of the Securities Act, the relevant Grantor will cause the issuer
thereof to (i) execute and deliver, and cause the directors and officers of such
issuer to execute and deliver, all such instruments and documents, and do or
cause to be done all such other acts as may be, in the opinion of the
Administrative Agent, necessary or advisable to register the Pledged Collateral,
or that portion thereof to be sold, under the provisions of the Securities Act,
(ii) use its best efforts to cause the registration statement relating thereto
to become effective and to remain effective for a period of one year from the
date of the first public offering of the Pledged Collateral, or that portion
thereof to be sold and (iii) make all amendments thereto and/or to the related
prospectus which, in the opinion of the Administrative Agent, are necessary or
advisable, all in conformity with the requirements of the Securities Act and the
rules and regulations of the Securities and Exchange Commission applicable
thereto. Each Grantor agrees to cause such issuer to comply with the provisions
of the securities or "Blue Sky" laws of any and all jurisdictions which the
Administrative Agent shall designate and to make available to its security
holders, as soon as practicable, an earnings statement (which need not be
audited) which will satisfy the provisions of Section 11(a) of the Securities
Act.

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

            (c) Each Grantor agrees to use its best efforts to do or cause to be
done all such other acts as may be necessary to make such sale or sales of all
or any portion of the Pledged Collateral pursuant to this Section 5.5 valid and
binding and in compliance with any and all other applicable Requirements of Law.
Each Grantor further agrees that a breach of any of the covenants contained in
this Section 5.5 will cause irreparable injury to the Administrative Agent and
other Secured Parties, that the Administrative Agent and the other Secured
Parties have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this Section 5.5 shall be
specifically enforceable against such Grantor, and

                                       19

<PAGE>

such Grantor hereby waives and agrees not to assert any defenses against an
action for specific performance of such covenants except for a defense that no
Event of Default has occurred under the Credit Agreement.

            Section 5.6 Waiver; Deficiency. Each Grantor shall remain liable for
any deficiency if the proceeds of any sale or other disposition of the
Collateral are insufficient to pay the Secured Obligations and the fees and
disbursements of any attorneys employed by the Administrative Agent or any other
Secured Party to collect such deficiency.

            ARTICLE VI. THE ADMINISTRATIVE AGENT

            Section 6.1 Administrative Agent's Appointment as Attorney-in-Fact.

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

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

            (ii) in the case of any Intellectual Property, execute and deliver,
      and have recorded, any and all agreements, instruments, documents and
      papers as the Administrative Agent may request to evidence the
      Administrative Agent's security interest in such Intellectual Property and
      the goodwill and General Intangibles of such Grantor relating thereto or
      represented thereby;

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

            (iv) execute, in connection with any sale provided for in Section
      5.1 or 5.5, any endorsements, assignments or other instruments of
      conveyance or transfer with respect to the Collateral; and

            (v) (A) direct any party liable for any payment under any of the
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Administrative Agent or as the Administrative
      Agent shall direct; (B) ask or demand for,

                                       20

<PAGE>

      collect, and receive payment of and receipt for, any and all moneys,
      claims and other amounts due or to become due at any time in respect of or
      arising out of any Collateral; (C) sign and indorse any invoices, freight
      or express bills, bills of lading, storage or warehouse receipts, drafts
      against debtors, assignments, verifications, notices and other documents
      in connection with any of the Collateral; (D) commence and prosecute any
      suits, actions or proceedings at law or in equity in any court of
      competent jurisdiction to collect the Collateral or any portion thereof
      and to enforce any other right in respect of any Collateral; (E) defend
      any suit, action or proceeding brought against such Grantor with respect
      to any Collateral; (F) settle, compromise or adjust any such suit, action
      or proceeding and, in connection therewith, give such discharges or
      releases as the Administrative Agent may deem appropriate; (G) assign any
      Copyright, Patent or Trademark (along with the goodwill of the business to
      which any such Trademark pertains), throughout the world for such term or
      terms, on such conditions, and in such manner, as the Administrative Agent
      shall in its sole discretion determine, including without limitation the
      execution and filing of any documents necessary to effectuate and/or
      record such assignment; and (H) generally, sell, transfer, pledge and make
      any agreement with respect to or otherwise deal with any of the Collateral
      as fully and completely as though the Administrative Agent were the
      absolute owner thereof for all purposes, and do, at the Administrative
      Agent's option and such Grantor's expense, at any time, or from time to
      time, all acts and things which the Administrative Agent deems necessary
      to protect, preserve or realize upon the Collateral and the Administrative
      Agent's and the other Secured Parties' security interests therein and to
      effect the intent of this Security Agreement, all as fully and effectively
      as such Grantor might do.

Anything in this Section 6.1(a) to the contrary notwithstanding, the
Administrative Agent agrees that it will not exercise any rights under the power
of attorney provided for in this Section 6.1(a) unless an Event of Default shall
be continuing.

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

            (c) The expenses of the Administrative Agent incurred in connection
with actions undertaken as provided in this Section 6.1, together with interest
thereon at a rate per annum equal to the default rate per annum above the
highest interest rate which would then be payable on Revolving Loans that are
Base Rate Loans under the Credit Agreement, from the date of payment by the
Administrative Agent to the date reimbursed by the relevant Grantor, shall be
payable by such Grantor to the Administrative Agent on demand.

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

            Section 6.2 Duty of Administrative Agent. The Administrative Agent's
sole duty with respect to the custody, safekeeping and physical preservation of
the Collateral in its possession shall be to deal with it in the same manner as
the Administrative Agent deals with similar property for its own account.
Neither the Administrative Agent, any other Secured Party nor any of their
respective officers, directors, employees or agents shall be

                                       21

<PAGE>

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

            Section 6.3 Execution of Financing Statements. Each Grantor
authorizes the Administrative Agent at any time and from time to time to file or
record financing statements and other filing or recording documents or
instruments with respect to the Collateral without the signature of such Grantor
in such form and in such offices as the Administrative Agent reasonably
determines appropriate to perfect the security interests granted to the
Administrative Agent for the benefit of the Secured Parties under this Security
Agreement. A photographic or other reproduction of this Security Agreement shall
be sufficient as a financing statement or other filing or recording document or
instrument for filing or recording in any jurisdiction.

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

            ARTICLE VII. MISCELLANEOUS

            Section 7.1 Amendments in Writing. None of the terms or provisions
of this Security Agreement may be waived, amended, supplemented or otherwise
modified except in accordance with Section 11.1 of the Credit Agreement.

            Section 7.2 Notices. All notices, requests and demands to or upon
the Administrative Agent or any Grantor hereunder shall be effected in the
manner provided for in Section 11.12 of the Credit Agreement; provided, however,
that any such notice, request or demand to or upon any Grantor shall be
addressed in care of the Borrower at the Borrower's notice address set forth in
such Section 11.12.

            Section 7.3 No Waiver by Course of Conduct; Cumulative Remedies.
Neither the Administrative Agent nor any other Secured Party shall by any act
(except by a written instrument pursuant to Section 7.1), delay, indulgence,
omission or otherwise, be deemed to have waived any right or remedy hereunder or
to have acquiesced in any Default or Event of

                                       22

<PAGE>

Default. No failure to exercise, nor any delay in exercising, on the part of the
Administrative Agent or any other Secured Party, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. A
waiver by the Administrative Agent or any other Secured Party of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Administrative Agent or such other Secured Party would
otherwise have on any future occasion. The rights and remedies herein provided
are cumulative, may be exercised singly or concurrently and are not exclusive of
any other rights or remedies provided by law.

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

            Section 7.5 Counterparts. This Security Agreement may be executed by
one or more of the parties to this Security Agreement on any number of separate
counterparts (including by telecopy), and all of said counterparts taken
together shall be deemed to constitute one and the same agreement.

            Section 7.6 Severability. Any provision of this Security Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

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

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

            Section 7.9 Governing Law. This Security Agreement and the rights
and obligations of the parties hereto shall be governed by, and construed and
interpreted in accordance with, the law of the State of New York.

            Section 7.10 Additional Grantors. If, pursuant to Section 7.15 of
the Credit Agreement, the Borrower shall be required to cause any Subsidiary
that is not a Grantor to become a Grantor hereunder, such Subsidiary shall
execute and deliver to the Administrative Agent a Joinder Agreement in the form
of Annex 4 and shall thereafter for all purposes be a party hereto and have the
same rights, benefits and obligations as a Grantor party hereto on the Closing
Date.

            Section 7.11 Release of Collateral.

            (a) At the time provided in Section 10.7(b)(i) of the Credit
Agreement, the Collateral shall be released from the Lien created hereby and
this Security Agreement and all

                                       23

<PAGE>

obligations (other than those expressly stated to survive such termination) of
the Administrative Agent and each Grantor hereunder shall terminate, all without
delivery of any instrument or performance of any act by any party, and all
rights to the Collateral shall revert to the Grantors. At the request and sole
expense of any Grantor following any such termination, the Administrative Agent
shall deliver to such Grantor any Collateral of such Grantor held by the
Administrative Agent hereunder and execute and deliver to such Grantor such
documents as such Grantor shall reasonably request to evidence such termination.

            (b) If any of the Collateral shall be sold or disposed of by any
Grantor in a transaction permitted by the Credit Agreement, the Collateral so
sold or disposed of shall be released from the Lien created hereby to the extent
provided in Section 10.7(b)(ii) or (iii) of the Credit Agreement and, in
connection therewith, the Administrative Agent, at the request and sole expense
of the Borrower, shall execute and deliver to the Borrower all releases or other
documents reasonably necessary or desirable for the release of the Lien created
hereby on such Collateral. At the request and sole expense of the Borrower, a
Grantor shall be released from its obligations hereunder in the event that all
the capital stock of such Grantor shall be so sold or disposed; provided,
however, that the Borrower shall have delivered to the Administrative Agent, at
least ten Business Days prior to the date of the proposed release, a written
request for release identifying the relevant Grantor and the terms of the sale
or other disposition in reasonable detail, including the price thereof and any
expenses in connection therewith, together with a certification by the Borrower
stating that such transaction is in compliance with the Credit Agreement and the
other Loan Documents.

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

                                                                          [Date]

Ladies and Gentlemen:

            Reference is made to account no. [__________] maintained with you
(the "Bank") by [           ] (the "Company") into which funds are deposited
from time to time (the "Account"). The Company has entered into a Credit
Agreement, dated as of _________ __,____ (as the same may be amended, restated,
supplemented or otherwise modified from time to time, the "Credit Agreement"),
among the Company, the Lenders and Issuers party thereto and Citicorp USA, Inc.,
as administrative agent for the Lenders and Issuers (in such capacity the
"Administrative Agent").

            Pursuant to the Credit Agreement and related documents, the Company
has granted to the Administrative Agent, for the benefit of the Secured Parties,
a security interest in certain property of the Company, including, among other
things, accounts, inventory, equipment, instruments, general intangibles and all
proceeds thereof (the "Collateral"). Payments with respect to the Collateral are

            The Company hereby transfers to the Administrative Agent exclusive
ownership and control of, and all of its right, title and interest in and to,
the Account and all funds and other property on deposit therein. By your
execution of this letter agreement, you (i) agree that you will comply with
instructions originated by the Administrative Agent directing disposition of the
funds and other property on deposit in the Account without further consent of
the Company, and (ii) acknowledge that the Administrative Agent now has
exclusive ownership and control of the Account, that all funds in the Account
shall be transferred to the Administrative Agent as provided herein, that the
Account is being maintained by you for the benefit of the Administrative Agent
and that all amounts and other property therein are held by you as custodian for
the Administrative Agent.

            Except as provided in paragraphs (b)(iii) and (e) below, the Account
shall not be subject to deduction, set-off, banker's lien, counterclaim,
defense, recoupment or any other right in favor of any person or entity other
than the Administrative Agent. By your execution of this letter agreement you
also acknowledge that, as of the date hereof, you have received no notice of any
other pledge or assignment of the Account and have not executed any agreements
with third parties covering the disposition of funds in the Account. You agree
with the Administrative Agent as follows:

            (a) Notwithstanding anything to the contrary or any other agreement
      relating to the Account, the Account is and will be maintained for the
      benefit of the Administrative Agent, will be entitled "Citicorp USA, Inc.
      [name of Company] Account" and will be subject to written instructions
      only from an authorized officer of the Administrative Agent.

            (b) [ A post office box (the "Lockbox") has been rented in the name
      of the

      such Lockbox is:

                                [Insert address]

      Your authorized representatives will have access to the Lockbox under the
      authority given by the Company to the post office and will make regular
      pick-ups from the Lockbox timed to gain maximum benefit of early
      presentation and availability of funds. You will endorse process all
      checks received in the Lockbox and deposit such checks (to the extent
      eligible) in the Account in accordance with the procedures set forth
      below.

                  (i) You will follow your usual operating procedures for the
            handling of any [checks received from the Lockbox or other]
            remittance received in the Account that contains restrictive
            endorsements, irregularities (such as a variance between the written
            and numerical amounts), undated or postdated items, missing
            signatures, incorrect payees and the like.

                  (ii) You will endorse and process all eligible checks and
            other remittance items not covered by subparagraph (iii) below and
            deposit such checks and remittance items in the Account.

                  (iii) You will mail all checks returned unpaid because of
            uncollected or insufficient funds under appropriate advice to the
            Company (with a copy of the notification of return to the
            Administrative Agent). You may charge the Account for the amounts of
            any returned check that has been previously credited to the Account.
            To the extent insufficient funds remain in the Account to cover any
            such returned check, the Company shall indemnify you for the
            uncollected amount of such returned check upon your demand. [In the
            case where the proceeds of any returned check have been transferred
            to the Administrative Agent pursuant to the terms hereof and the
            Company has not reimbursed you for such returned check, the
            Administrative Agent agrees to reimburse you for the amount of such
            returned check; provided, however, that you have delivered a copy of
            such returned check to the Administrative Agent together with
            evidence that the proceeds of such check were so forwarded to the
            Administrative Agent.](1)

                  (iv) You will maintain a record of all checks and other
            remittance items received in the Account and, in addition to
            providing the Company with photostatic copies thereof, vouchers,
            enclosures and the like of such checks and remittance items on a
            daily basis, furnish to the Administrative Agent a monthly statement
            of the Account to: Citicorp USA, Inc., as Administrative Agent, 388

[Name and Address
of Approved Securities
Intermediary]

                                                                          [Date]

Ladies and Gentlemen:

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

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

      1.    maintain the Account, as "________ - Citicorp USA Control Account";

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

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

      4.    honor only the instructions or entitlement orders in regard to or in
            connection with the Account given by an Authorized Officer of the
            Pledgee, except that until such time as the Pledgee gives a written
            notice to the Approved Securities Intermediary that the Pledgor's
            rights under this sentence have been terminated (on which notice the
            Approved Securities Intermediary may rely exclusively), the Pledgor
            acting through an Authorized Officer may (a) exercise any voting
            rights that it may have with respect to any of the Assets, (b) give
            instructions to enter into purchase or sale transactions in the
            Account and (c) withdraw and receive for its own use all regularly
            scheduled interest [and dividends] paid with respect to the Assets
            [and all cash proceeds of any sale of Assets] ("Permitted
            Withdrawals"); provided, however, that unless the Pledgee has
            consented to the specific transaction, the Pledgor shall not
            instruct the Approved Securities Intermediary to deliver and, except
            as may be required by law or by court order, the Approved Securities
            Intermediary shall not deliver, cash and/or securities, or proceeds
            from the sale of, or distributions on, such securities out of the
            Account to the Pledgor or to any other person or entity other than
            Permitted Withdrawals.

                                      A2-1

<PAGE>

            By its signature below, the Approved Securities Intermediary agrees
to comply with the entitlement orders and instructions of an Authorized Officer
of the Pledgee (including without limitation any instructions with respect to
sales, trades, transfers and withdrawals of cash or other of the Assets) without
the consent of the Pledgor or any other person (it being understood and agreed
by the Pledgor that the Approved Securities Intermediary shall have no duty or
obligation whatsoever of any kind or character to have knowledge of the terms of
the Pledge and Security Agreement or to determine whether or not an event of
default exists thereunder). The Pledgor hereby agrees to indemnify and hold
harmless the Approved Securities Intermediary, its affiliates, officers and
employees from and against any and all claims, causes of action, liabilities,
lawsuits, demands and/or damages, including any and all court costs and
reasonable attorney's fees, that may result by reason of the Approved Securities
Intermediary complying with such instructions of the Pledgee. In the event that
the Approved Securities Intermediary is sued or becomes involved in litigation
as a result of complying with the above stated written instructions, the Pledgor
and the Pledgee agree that the Approved Securities Intermediary shall be
entitled to charge all costs and fees it incurs in connection with such
litigation to the Assets in the Account and withdraw such sums as the costs and
charges accrue.

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

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

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

            As long as the Assets are pledged to the Pledgee: (i) the Approved
Securities Intermediary will not invade the Assets to cover margin debits or
calls in any other accounts of the Pledgor and (ii) the Approved Securities
Intermediary agrees that, except for liens resulting from customary commissions,
fees, or charges based upon transactions in the Account, it subordinates in
favor of the Pledgee any security interest, lien or right of setoff the Approved
Securities Intermediary may have. The Approved Securities Intermediary
acknowledges that it has not received notice of any other security interest in
the Account or the Assets. In the event any such notice is received, the
Approved Securities Intermediary will promptly notify the Pledgee. The Pledgor

rights that the Approved Securities Intermediary might otherwise have.

[NAME AND ADDRESS OF BAILEE]

            Re:   National Steel Corporation

Ladies and Gentlemen:

            This letter is to confirm that National Steel Corporation, a
Delaware corporation (the "Company"), from time to time, delivers inventory to
you for processing, warehousing or storage (such inventory heretofore or
hereafter delivered to you being referred to as "Bailed Goods") and that title
to the Bailed Goods remains with the Company at all times.

            This letter is also to advise you that, pursuant to a certain Pledge
and Security Agreement (the "Security Agreement") executed by the Company, the
Company has granted to Citicorp USA, Inc. as administrative agent for certain
financial institutions (the "Agent"), a security interest in, among other
things, all of the Company's now owned and hereafter acquired inventory,
including, without limitation, the Bailed Goods, to secure obligations of the
Company under a certain Credit Agreement dated as of September __, 2001 (the
"Credit Agreement") among the Company, certain financial institutions from time
to time party thereto and the Agent.

            This letter serves as notice to you pursuant to Sections 9-312(d)
and 9-313(c) of the Uniform Commercial Code of the Agent's interest in the
Bailed Goods. In order to protect the Company's ownership interest and the
Agent's security interests in the Bailed Goods, the Company asks that you
execute this letter (i) to acknowledge and confirm that you are holding and will
hold the Bailed Goods on bailment for the benefit of the Agent for processing,
warehousing or storage for the benefit of the Agent; such Bailed Goods are the
Company's property and subject to the Agent's security interest; such security
interest in the Bailed Goods is and shall be senior to all liens, claims and
interests; and you will notify all of your successors and assigns of the
existence of the agreements contained herein and (ii) to evidence your agreement
that if, at any time hereafter, the Agent shall notify you in writing that the
Company has defaulted on its obligations under the Credit Agreement, you will
comply with the Agent's written instructions as to the disposition of the Bailed
Goods. Until the Credit Agreement has been terminated and the Agent and the
Lenders have been paid in full, you shall not deduct from or offset against any
amounts due and owing by the Company to you at any

<PAGE>

time hereafter by applying any of the Bailed Goods in payment for processing or
storage services provided by you to the Company.

            The Company agrees that you shall have no liability to the Company
if you comply with the Agent's written directions and the Company agrees to
reimburse you for all reasonable costs and expenses (including processing,
warehousing and storage fees) incurred by you as a direct result of such
compliance.

                                        Very truly yours,

                                        NATIONAL STEEL CORPORATION

                                     FORM OF
                          LANDLORD'S WAIVER AND CONSENT

            THIS LANDLORD'S WAIVER AND CONSENT (this "Consent"), made and
entered as of September __, 2001, by _____________________, (the "Landlord") in
favor of CITICORP USA, INC., as administrative agent (the "Agent") for the
lenders and the issuers (collectively, the "Lenders") party to that certain
Credit Agreement dated September 28, 2001 (the "Credit Agreement").

                                   BACKGROUND:

            A. National Steel Corporation (the "Lessee") is the lessee under
that certain lease dated ____________ (the "Lease") between the Landlord and the
Lessee covering certain premises located at _____________________________ (the
"Premises").

            B. Lessee has entered into the Credit Agreement with the Agent and
the Lenders.

            C. As a condition to extending such loans and other financial
accommodations, the Lenders have required, among other things, that the Lessee
grant to the Agent, for its own benefit and the ratable benefit of the Lenders,
security interests in and liens upon certain assets of the Lessee, including
without limitation all of the Lessee's accounts, inventory, certain movable
machinery and equipment, general intangibles, investment property, documents,
instruments, chattel paper, bank accounts, books and records and all other
personal property of Lessee, in each case whether now or hereafter existing or
now owned or hereafter acquired (collectively, the "Collateral"), a portion of
which Collateral is and may hereafter be located on or about the Premises.

            NOW, THEREFORE, in order to induce the Lenders to extend such loans
and other financial accommodations to the Lessee, which will aid the Lessee in
meeting its obligations to the Landlord, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
Landlord hereby agrees with the Agent as follows:

            1. The Agent's security interests and liens in the Collateral shall
be superior to any title or interest which the Landlord may at any time have
therein, and, during the term of this Agreement, the Landlord will not assert
against any of the Collateral any title or any statutory, common law,
contractual or possessory lien, including, without limitation, rights of levy or
distraint for rent, all of which the Landlord hereby subordinates in favor of
the Agent and the Lenders.

<PAGE>

            2. The Landlord hereby agrees that none of the Collateral located on
the Premises shall be deemed to be fixtures and hereby disclaims any and all
right, title, interest or claim in or to the Collateral and any cash or non-cash
proceeds of the Collateral (except with respect to the subordinated landlord
lien referred to in Section 1 above).

            3. In the event that Lessee defaults in its obligations under the
Lease, Landlord hereby agrees to give the Agent written notice of default under
the Lease, at the same time and in the same manner as such notice is given to
the Lessee and further agrees that the Agent may, but shall not be obligated to,
cure such defaults, at its option, within the applicable notice and cure
periods.

            4. If, for any reason whatsoever, the Landlord either deems itself
entitled to redeem or to take possession of the Premises during the term of the
Lease or intends to sell or otherwise transfer all or any part of its interest
in the Premises, the Landlord agrees to notify the Agent at least thirty (30)
days before taking such action.

            5. If the Lessee defaults on its obligations to the Agent and the
Lenders, and, as a result, the Agent undertakes to enforce its security interest
in the Collateral, the Landlord (a) will cooperate with the Agent in its efforts
to assemble all of the Collateral located on the Premises; (b) will permit the
Agent to remain on the Premises for forty-five (45) days after the Agent
notifies the Landlord of the default, or, at the Agent's option, to remove the
Collateral from the Premises within a reasonable time, not to exceed forty-five
(45) days after the Agent notifies the Landlord of the default, provided the
Agent pays the rental payments due under the Lease for the period of time the
Agent uses the Premises; and (c) will not hinder the Agent's actions in
enforcing its liens on the Collateral, it being agreed that use or occupancy of
the Premises by the Agent as set forth herein shall not constitute an assumption
by the Agent of the Lease or of any obligations thereunder other than for rent
due for any such occupancy as stated herein above.

            6. The Landlord states that the Lease is presently in full force and
effect, that all rentals have been paid up to date, and that the Lease is not in
default.

            7. This Consent shall remain in full force and effect until all
obligations of the Lessee to the Agent and the Lenders have been paid and
satisfied in full and the Agent and the Lenders have terminated their financing
agreements with the Lessee pursuant to the Credit Agreement.

            8. The provisions of this Consent may not be modified or terminated
orally, and shall be binding upon the successors and assigns of the Landlord,
and upon any successor owner or transferee of the Premises and shall inure to
the benefit of the Agent, the Lenders and each one's respective successors and
assigns.

            9. All notices shall be in writing and shall be mailed by first
class registered or certified mail, postage prepaid, as follows:

                        (a)   If to the Agent:

                                    GUARANTY

            GUARANTY dated September 28, 2001 by National Steel Pellet Company,
a Delaware corporation ("Pellet"), National Steel Funding Company, a Delaware
corporation ("NSFC"), NS Holdings Corporation, a Delaware corporation ("NS
Holdings"), ProCoil Corporation, a Delaware corporation ("ProCoil") and each of
the other entities which becomes a party hereto pursuant to Section 22 hereof
(collectively, together with Pellet, NSFC, NS Holdings and ProCoil, the
"Guarantors" and, each individually, a "Guarantor"), in favor of the
Administrative Agent, each Lender, each Issuer and each other holder of an
Obligation (as each such term is defined in the Credit Agreement referred to
below) (each, a "Guaranteed Party" and, collectively the "Guaranteed Parties").

                              W I T N E S S E T H:

            WHEREAS, pursuant to the Credit Agreement dated as of September 28,
2001 (as the same may be amended, restated, supplemented or otherwise modified
from time to time, the "Credit Agreement"; capitalized terms defined therein and
used herein having the meanings given to them in the Credit Agreement) among
National Steel Corporation, a Delaware corporation (the "Borrower"), the Lenders
and Issuers party thereto, Citicorp USA, Inc. as administrative agent for the
Lenders and Issuers, the Lenders and Issuers have severally agreed to make
extensions of credit to the Borrower upon the terms and subject to the
conditions set forth therein; and

            WHEREAS, each Guarantor will receive substantial direct and indirect
benefits from the making of the Loans, the issuance of the Letters of Credit and
the granting of the other financial accommodations to the Borrower under the
Credit Agreement; and

            WHEREAS, as a condition to the making of the Loans and the issuance
of the Letter of Credit that each Guarantor execute and deliver this Guaranty
for the benefit of the Guaranteed Parties;

            NOW, THEREFORE, in consideration of the premises set forth above,
the terms and conditions contained herein, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto hereby agree as follows:

            Section 1. Guaranty.

            (a) To induce the Lenders to make the Loans and the Issuers to issue
Letters of Credits, each Guarantor hereby absolutely, unconditionally and
irrevocably guarantees, as primary obligor and not merely as surety, the full
and punctual payment when due, whether at stated maturity or earlier, by reason
of acceleration, mandatory prepayment or otherwise in accordance herewith or any
other Loan Document, of all the Obligations, whether or not from time to time
reduced or extinguished or hereafter increased or incurred, whether or not
recovery may be or hereafter may become barred by any statute of limitations,
and whether enforceable or unenforceable as against the Borrower, now or
hereafter existing, or due or to become due, including principal, interest
(including interest at the contract rate applicable upon default accrued or
accruing after the commencement of any proceeding under the Bankruptcy Code,
whether or not such interest is an allowed claim in such proceeding), fees and
costs of collection. This Guaranty constitutes an absolute guaranty of payment
and performance and not of collection.

                                      F-1

<PAGE>

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

            Section 2.. Limitation of Guaranty. Any term or provision of this
Guaranty or any other Loan Document to the contrary notwithstanding, the maximum
aggregate amount of the Obligations for which any Guarantor shall be liable
shall not exceed the maximum amount for which such Guarantor can be liable
without rendering this Guaranty or any other Loan Document, as it relates to
such Guarantor, subject to avoidance under applicable law relating to fraudulent
conveyance or fraudulent transfer (including section 548 of the Bankruptcy Code
or any applicable provisions of comparable state law) (collectively, "Fraudulent
Transfer Laws"), in each case after giving effect (a) to all other liabilities
of such Guarantor, contingent or otherwise, that are relevant under such
Fraudulent Transfer Laws (specifically excluding, however, any liabilities of
such Guarantor in respect of intercompany Indebtedness to the Borrower to the
extent that such Indebtedness would be discharged in an amount equal to the
amount paid by such Guarantor hereunder) and (b) to the value as assets of such
Guarantor (as determined under the applicable provisions of such Fraudulent
Transfer Laws) of any rights to subrogation, contribution, reimbursement,
indemnity or similar rights held by such Guarantor pursuant to (i) applicable
law, (ii) Section 3 of this Guaranty or (iii) any other agreement providing for
an equitable allocation among such Guarantor and other Subsidiaries or
Affiliates of the Borrower of obligations arising under this Guaranty or other
guaranties of the Obligations by such parties.

            Section 3. Contribution. To the extent that any Guarantor shall be
required hereunder to pay a portion of the Obligations which shall exceed the
greater of (i) the amount of the economic benefit actually received by such
Guarantor from the Revolving Loans and (ii) the amount which such Guarantor
would otherwise have paid if such Guarantor had paid the aggregate amount of the
Obligations (excluding the amount thereof repaid by the Borrower) in the same
proportion as such Guarantor's net worth at the date enforcement hereunder is
sought bears to the aggregate net worth of all the Guarantors at the date
enforcement hereunder is sought, then such Guarantor shall be reimbursed by such
other Guarantors for the amount of such excess, pro rata, based on the
respective net worths of such other Guarantors at the date enforcement hereunder
is sought.

            Section 4. Authorization; Other Agreements. The Guaranteed Parties
are hereby authorized, without notice to or demand upon any Guarantor, which
notice or demand is expressly waived hereby, and without discharging or
otherwise affecting the obligations of any

                                      F-2

Guarantor hereunder (which shall remain absolute and unconditional
notwithstanding any such action or omission to act), from time to time, to:

            (a) supplement, renew, extend, accelerate or otherwise change the
time for payment of, or other terms relating to, the Obligations, or any part of
them, or otherwise modify, amend or change the terms of any promissory note or
other agreement, document or instrument (including, without limitation, the
other Loan Documents) now or hereafter executed by the Borrower and delivered to
the Guaranteed Parties or any of them, including, without limitation, any
increase or decrease of principal or the rate of interest thereon;

            (b) waive or otherwise consent to noncompliance with any provision
of any instrument evidencing the Obligations, or any part thereof, or any other
instrument or agreement in respect of the Obligations (including the other Loan
Documents) now or hereafter executed by the Borrower and delivered to the
Guaranteed Parties or any of them;

            (c) accept partial payments on the Obligations;

            (d) receive, take and hold additional security or collateral for the
payment of the Obligations or any part of them and exchange, enforce, waive,
substitute, liquidate, terminate, abandon, fail to perfect, subordinate,
transfer, otherwise alter and release any such additional security or
collateral;

            (e) settle, release, compromise, collect or otherwise liquidate the
Obligations or accept, substitute, release, exchange or otherwise alter, affect
or impair any security or collateral for the Obligations or any part of them or
any other guaranty therefor, in any manner;

            (f) add, release or substitute any one or more other guarantors,
makers or endorsers of the Obligations or any part of them and otherwise deal
with the Borrower or any other guarantor, maker or endorser;

            (g) apply to the Obligations any and all payments or recoveries from
the Borrower, from any other guarantor, maker or endorser of the Obligations or
any part of them or from any Guarantor to the Obligations in such order as
provided herein whether such Obligations are secured or unsecured or guaranteed
or not guaranteed by others;

            (h) apply any and all payments or recoveries from any Guarantor of
the Obligations or sums realized from security furnished by such Guarantor upon
its indebtedness or obligations to the Guaranteed Parties, or any of them,
whether or not such indebtedness or obligations relate to the Obligations; and

            (i) refund at any time any payment received by any Guaranteed Party
in respect of any of the Obligations, and payment to such Guaranteed Party of
the amount so refunded shall be fully guaranteed hereby even though prior
thereto this Guaranty shall have been cancelled or surrendered (or any release
or termination of any Collateral by virtue thereof), and such prior cancellation
or surrender shall not diminish, release, discharge, impair or otherwise affect
the obligations of any Guarantor hereunder in respect of the amount so refunded
(and any Collateral so released or terminated shall be reinstated with respect
to such obligations);

even if any right of reimbursement or subrogation or other right or remedy of
any Guarantor is extinguished, affected or impaired by any of the foregoing
(including, without limitation, any

                                      F-3

<PAGE>

election of remedies by reason of any judicial, non-judicial or other proceeding
in respect of the Obligations which impairs any subrogation, reimbursement or
other right of such Guarantor).

            Section 5. Guaranty Absolute and Unconditional. Each Guarantor
hereby waives any defense of a surety or guarantor or any other obligor on any
obligations arising in connection with or in respect of any of the following and
hereby agrees that its obligations under this Guaranty are absolute and
unconditional and shall not be discharged or otherwise affected as a result of:

            (a) the invalidity or unenforceability of any of the Borrower's
obligations under the Credit Agreement or any other Loan Document or any other
agreement or instrument relating thereto, or any security for, or other guaranty
of the Obligations or any part of them, or the lack of perfection or continuing
perfection or failure of priority of any security for the Obligations or any
part of them;

            (b) the absence of any attempt to collect the Obligations or any
part of them from the Borrower or other action to enforce the same;

            (c) failure by any Guaranteed Party to take any steps to perfect and
maintain any Lien on, or to preserve any rights to, any Collateral;

            (d) any Guaranteed Party's election, in any proceeding instituted
under chapter 11 of the Bankruptcy Code, of the application of Section
1111(b)(2) of the Bankruptcy Code;

            (e) any borrowing or grant of a Lien by the Borrower, as
debtor-in-possession, or extension of credit, under Section 364 of the
Bankruptcy Code;

            (f) the disallowance, under Section 502 of the Bankruptcy Code, of
all or any portion of any Guaranteed Party's claim (or claims) for repayment of
the Obligations;

            (g) any use of cash collateral under Section 363 of the Bankruptcy

            (h) any agreement or stipulation as to the provision of adequate
protection in any bankruptcy proceeding;

            (i) the avoidance of any Lien in favor of the Guaranteed Parties or
any of them for any reason;

            (j) any bankruptcy, insolvency, reorganization, arrangement,
readjustment of debt, liquidation or dissolution proceeding commenced by or
against the Borrower, any Guarantor or any of the Borrower's other Subsidiaries,
including without limitation, any discharge of, or bar or stay against
collecting, all or any of the Obligations (or any part of them or interest
thereon) in or as a result of any such proceeding;

            (k) failure by any Guaranteed Party to file or enforce a claim
against the Borrower or its estate in any bankruptcy or insolvency case or
proceeding;

            (l) any action taken by any Guaranteed Party that is authorized
hereby;

                                      F-4

<PAGE>

            (m) any election following the occurrence of an Event of Default by
any Guaranteed Party to proceed separately against the personal property
Collateral in accordance with such Guaranteed Party's rights under the UCC or,
if the Collateral consists of both personal and real property, to proceed
against such personal and real property in accordance with such Guaranteed
Party's rights with respect to such real property; or

            (n) any other circumstance which might otherwise constitute a legal
or equitable discharge or defense of a surety or guarantor or any other obligor
on any obligations, other than the payment in full of the Obligations.

            Section 6. Waivers. Each Guarantor hereby waives diligence,
promptness, presentment, demand for payment or performance and protest and
notice of protest, notice of acceptance and any other notice in respect of the
Obligations or any part of them, and any defense arising by reason of any
disability or other defense of the Borrower. Each Guarantor shall not, until the
Obligations are irrevocably paid in full and the Commitments have been
terminated, assert any claim or counterclaim it may have against the Borrower or
set off any of its obligations to the Borrower against any obligations of the
Borrower to it. In connection with the foregoing, each Guarantor covenants that
its obligations hereunder shall not be discharged, except by complete
performance.

            Section 7. Reliance. Each Guarantor hereby assumes responsibility
for keeping itself informed of the financial condition of the Borrower and any
and all endorsers and/or other guarantors of all or any part of the Obligations,
and of all other circumstances bearing upon the risk of nonpayment of the
Obligations, or any part thereof, that diligent inquiry would reveal, and each
Guarantor hereby agrees that no Guaranteed Party shall have any duty to advise
any Guarantor of information known to it regarding such condition or any such
circumstances. In the event any Guaranteed Party, in its sole discretion,
undertakes at any time or from time to time to provide any such information to
any Guarantor, such Guaranteed Party shall be under no obligation (i) to
undertake any investigation not a part of its regular business routine, (ii) to
disclose any information which such Guaranteed Party, pursuant to accepted or
reasonable commercial finance or banking practices, wishes to maintain
confidential or (iii) to make any other or future disclosures of such
information or any other information to any Guarantor.

            Section 8. Waiver of Subrogation and Contribution Rights. Until the
Obligations have been irrevocably paid in full and the Commitments have been
terminated, the Guarantors shall not enforce or otherwise exercise any right of
subrogation to any of the rights of the Guaranteed Parties or any part of them
against the Borrower or any right of reimbursement or contribution or similar
right against the Borrower by reason of this Agreement or by any payment made by
any Guarantor in respect of the Obligations.

            Section 9. Subordination. Each Guarantor hereby agrees that any
Indebtedness of the Borrower now or hereafter owing to any Guarantor, whether
heretofore, now or hereafter created (the "Guarantor Subordinated Debt"), is
hereby subordinated to all of the Obligations, and that, except as permitted
under Section 8.5 of the Credit Agreement, the Guarantor Subordinated Debt shall
not be paid in whole or in part until the Obligations have been paid in full and
this Guaranty is terminated and of no further force or effect. No Guarantor
shall accept any payment of or on account of any Guarantor Subordinated Debt at
any time in contravention of the foregoing. Upon the occurrence and during the
continuance of an Event of Default, the Borrower shall pay to the Administrative
Agent any payment of all or any part of the

                                      F-5

<PAGE>

Guarantor Subordinated Debt and any amount so paid to the Administrative Agent
shall be applied to payment of the Obligations as provided in Section 2.13(f) of
the Credit Agreement. Each payment on the Guarantor Subordinated Debt received
in violation of any of the provisions hereof shall be deemed to have been
received by such Guarantor as trustee for the Guaranteed Parties and shall be
paid over to the Administrative Agent immediately on account of the Obligations,
but without otherwise affecting in any manner such Guarantor's liability hereof.
Each Guarantor agrees to file all claims against the Borrower in any bankruptcy
or other proceeding in which the filing of claims is required by law in respect
of any Guarantor Subordinated Debt, and the Administrative Agent shall be
entitled to all of such Guarantor's rights thereunder. If for any reason a
Guarantor fails to file such claim at least ten Business Days prior to the last
date on which such claim should be filed, such Guarantor hereby irrevocably
appoints the Administrative Agent as its true and lawful attorney-in-fact and is
hereby authorized to act as attorney-in-fact in such Guarantor's name to file
such claim or, in the Administrative Agent's discretion, to assign such claim to
and cause proof of claim to be filed in the name of the Administrative Agent or
its nominee. In all such cases, whether in administration, bankruptcy or
otherwise, the person or persons authorized to pay such claim shall pay to the
Administrative Agent the full amount payable on the claim in the proceeding,
and, to the full extent necessary for that purpose, each Guarantor hereby
assigns to the Administrative Agent all of such Guarantor's rights to any
payments or distributions to which such Guarantor otherwise would be entitled.
If the amount so paid is greater than such Guarantor's liability hereunder, the
Administrative Agent shall pay the excess amount to the party entitled thereto.
In addition, each Guarantor hereby irrevocably appoints the Administrative Agent
as its attorney-in-fact to exercise all of such Guarantor's voting rights in
connection with any bankruptcy proceeding or any plan for the reorganization of
the Borrower.

            Section 10. Default; Remedies. The obligations of each Guarantor
hereunder are independent of and separate from the Obligations. If any of the
Obligations is not paid when due, or upon any default of a Guarantor hereunder,
or upon any Event of Default under the Credit Agreement or upon any default by
the Borrower as provided in any other instrument or document evidencing all or
any part of the Obligations, the Administrative Agent may, at its sole election,
proceed directly and at once, without notice, against any Guarantor to collect
and recover the full amount or any portion of the Obligations then due, without
first proceeding against the Borrower or any other guarantor of the Obligations,
or against any Collateral under the Loan Documents or joining the Borrower or
any other guarantor in any proceeding against such Guarantor. At any time after
maturity of the Obligations, the Administrative Agent may (unless the
Obligations have been irrevocably paid in full), without notice to any Guarantor
and regardless of the acceptance of any Collateral for the payment hereof,
appropriate and apply toward the payment of the Obligations (i) any indebtedness
due or to become due from any Guaranteed Party to such Guarantor and (ii) any
moneys, credits or other property belonging to such Guarantor at any time held
by or coming into the possession of any Guaranteed Party or any of its
respective Affiliates.

            Section 11. Irrevocability. This Guaranty shall be irrevocable as to
any and all of the Obligations until the Commitments have been terminated and
all monetary Obligations then outstanding have been irrevocably repaid in cash,
at which time this Guaranty shall automatically be cancelled. Upon such
cancellation and at the written request of any Guarantor or its successors or
assigns, and at the cost and expense of such Guarantor or its successors or
assigns, the Administrative Agent shall execute in a timely manner a
satisfaction of this Guaranty

                                      F-6

<PAGE>

and such instruments, documents or agreements as are necessary or desirable to
evidence the termination of this Guaranty.

            Section 12. Setoff. Upon the occurrence and during the continuance
of an Event of Default, each Guaranteed Party and each Affiliate of a Guaranteed
Party may, without notice to any Guarantor and regardless of the acceptance of
any security or collateral for the payment hereof, appropriate and apply toward
the payment of all or any part of the Obligations (i) any indebtedness due or to
become due from such Guaranteed Party or Affiliate to such Guarantor, and (ii)
any moneys, credits or other property belonging to such Guarantor, at any time
held by or coming into the possession of such Guaranteed Party or Affiliate.

            Section 13. No Marshalling. Each Guarantor consents and agrees that
no Guaranteed Party or Person acting for or on behalf of any Guaranteed Party
shall be under any obligation to marshal any assets in favor of any Guarantor or
against or in payment of any or all of the Obligations.

            Section 14. Enforcement; Amendments; Waivers. No delay on the part
of any Guaranteed Party in the exercise of any right or remedy arising under
this Guaranty, the Credit Agreement, any of the other Loan Documents or
otherwise with respect to all or any part of the Obligations, the Collateral or
any other guaranty of or security for all or any part of the Obligations shall
operate as a waiver thereof, and no single or partial exercise by any such
Person of any such right or remedy shall preclude any further exercise thereof.
No modification or waiver of any of the provisions of this Guaranty shall be
binding upon any Guaranteed Party, except as expressly set forth in a writing
duly signed and delivered by the party making such modification or waiver.
Failure by any Guaranteed Party at any time or times hereafter to require strict
performance by the Borrower, any Guarantor, any other guarantor of all or any
part of the Obligations or any other Person of any of the provisions,
warranties, terms and conditions contained in any of the Loan Documents now or
at any time or times hereafter executed by such Persons and delivered to any
Guaranteed Party shall not waive, affect or diminish any right of any Guaranteed
Party at any time or times hereafter to demand strict performance thereof and
such right shall not be deemed to have been waived by any act or knowledge of
any Guaranteed Party, or its respective agents, officers or employees, unless
such waiver is contained in an instrument in writing, directed and delivered to
the Borrower or such Guarantor, as applicable, specifying such waiver, and is
signed by the party or parties necessary to give such waiver under the Credit
Agreement. No waiver of any Event of Default by any Guaranteed Party shall
operate as a waiver of any other Event of Default or the same Event of Default
on a future occasion, and no action by any Guaranteed Party permitted hereunder
shall in any way affect or impair any Guaranteed Party's rights and remedies or
the obligations of any Guarantor under this Guaranty. Any determination by a
court of competent jurisdiction of the amount of any principal and/or interest
owing by the Borrower to a Guaranteed Party shall be conclusive and binding on
each Guarantor irrespective of whether such Guarantor was a party to the suit or
action in which such determination was made.

            Section 15. Successors and Assigns. This Guaranty shall be binding
upon each Guarantor and upon the successors and assigns of such Guarantors and
shall inure to the benefit of the Guaranteed Parties and their respective
successors and assigns; all references herein to the Borrower and to the
Guarantors shall be deemed to include their respective successors and assigns.
The successors and assigns of the Guarantors and the Borrower shall include,
without

                                      F-7

<PAGE>

limitation, their respective receivers, trustees and debtors-in-possession. All
references to the singular shall be deemed to include the plural where the
context so requires.

            Section 16. Representations and Warranties; Covenants. Each
Guarantor hereby (a) represents and warrants that the representations and
warranties as to it made by the Borrower in Article IV of the Credit Agreement
are true and correct on each date as required by Section 3.2(b)(i) of the Credit
Agreement and (b) agrees to take, or refrain from taking, as the case may be,
each action that is necessary to be taken or not taken, as the case may be, so
that no Default or Event of Default is caused by the failure to take such action
or to refrain from taking such action by such Guarantor.

            Section 17. Governing Law. This Guaranty and the rights and
obligations of the parties hereto shall be governed by, and construed and
interpreted in accordance with, the law of the State of New York.

            Section 18. Submission to Jurisdiction; Service of Process.

            (a) Any legal action or proceeding with respect to this Guaranty,
and any of the other Loan Documents, may be brought in the courts of the State
of New York or of the United States of America for the Southern District of New
York, and, by execution and delivery of this Agreement, each Guarantor hereby
accepts for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts. The parties hereto
hereby irrevocably waive any objection, including any objection to the laying of
venue or based on the grounds of forum non conveniens, which any of them may now
or hereafter have to the bringing of any such action or proceeding in such
respective jurisdictions.

            (b) Each Guarantor hereby irrevocably consents to the service of any
and all legal process, summons, notices and documents in any suit, action or
proceeding brought in the United States of America arising out of or in
connection with this Guaranty or any of the other Loan Documents by the mailing
(by registered or certified mail, postage prepaid) or delivering of a copy of
such process to such Guarantor in care of the Borrower at the Borrower's address
specified in Section 11.12 of the Credit Agreement. Each Guarantor agrees that a
final 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.

            (c) Nothing contained in this Section 18 shall affect the right of
the Administrative Agent or any other Guaranteed Party to serve process in any
other manner permitted by law or commence legal proceedings or otherwise proceed
against a Guarantor in any other jurisdiction.

            (d) If for the purposes of obtaining judgment in any court it is
necessary to convert a sum due hereunder in Dollars into another currency, the
parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures the Administrative Agent could purchase Dollars with such
other currency at the spot rate of exchange quoted by the Administrative Agent
at 11:00 a.m. (New York time) on the Business Day preceding that on which final
judgment is given, for the purchase of Dollars, for delivery two Business Days
thereafter.

            Section 19. Waiver of Jury Trial. Each of the Administrative Agent,
the other Guaranteed Parties and each Guarantor irrevocably waives trial by jury
in any action or proceeding with respect to this Guaranty and any of the other
Loan Documents.

            Section 20. Notices. Any notice or other communication herein
required or permitted shall be given as provided in Section 11.12 of the Credit
Agreement and, in the case of any Guarantor, to such Guarantor in care of the
Borrower.

            Section 21. Severability. Wherever possible, each provision of this
Guaranty shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Guaranty shall be prohibited by or
invalid under such law, such provision shall be ineffective to the extent of
such prohibition or invalidity without invalidating the remainder of such
provision or the remaining provisions of this Guaranty.

            Section 22. Additional Guarantors. Each of the Guarantors agrees
that, if pursuant to Section 7.15 of the Credit Agreement the Borrower shall be
required to cause any Subsidiary that is not a Guarantor to become a Guarantor
hereunder, or if for any reason the Borrower desires any such Subsidiary to
become a Guarantor hereunder, such Subsidiary shall execute and deliver to the
Administrative Agent a Guaranty Supplement in substantially the form of Exhibit
A attached hereto and shall thereafter for all purposes be a party hereto and
have the same rights, benefits and obligations as a Guarantor party hereto on
the Effective Date.

            Section 23. Collateral. Each Guarantor hereby acknowledges and
agrees that its obligations under this Guaranty are secured pursuant to the
terms and provisions of the Collateral Documents executed by it in favor of the
Administrative Agent, for the benefit of the Secured Parties, and covenants that
it shall not grant any Lien with respect to its Property in favor, or for the
benefit, of any Person other than the Administrative Agent, for the benefit of
the Secured Parties.

            Section 24. Costs and Expenses. Each Guarantor agrees to pay or
reimburse the Administrative Agent and each of the other Guaranteed Parties upon
demand for all out-of-pocket costs and expenses, including, without limitation,
reasonable attorneys' fees (including allocated costs of internal counsel and
costs of settlement), incurred by the Administrative Agent and such other
Guaranteed Parties in enforcing this Guaranty or any security therefor or
exercising or enforcing any other right or remedy available in connection
herewith or therewith.

            Section 25. Waiver. Each Guarantor hereby irrevocably and
unconditionally waives, to the maximum extent not prohibited by law, any right
it may have to claim or recover any special, exemplary, punitive or
consequential damage in any legal action or proceeding in respect of this
Guaranty or any of the other Loan Documents.

            Section 26. Entire Agreement. This Guaranty, taken together with all
of the other Loan Documents executed and delivered by the Guarantors, represents
the entire agreement and understanding of the parties hereto and supersedes all
prior understandings, written and oral, relating to the subject matter hereof.

To    Citicorp USA, Inc., as Administrative
      Agent, Fleet Capital Corporation and
      The CIT Group/Business Credit Inc.,
      as Documentation Agents, Heller
      Financial, Inc. and GMAC Business

      Lead Arranger, and each of the Lenders and
      Issuers party to the Credit Agreement referred
      to below

            Re: National Steel Corporation, et al.

Ladies and Gentlemen:

            We have acted as counsel to National Steel Corporation (the
"Borrower"), National Steel Pellet Company, National Steel Funding Corporation,
NS Holdings Corporation, and ProCoil Corporation (together with the Borrower,
the "Loan Parties") in connection with the preparation, execution and delivery
of, and the consummation of the transactions contemplated by, the Credit
Agreement, dated as of September __, 2001 (the "Credit Agreement"), by and among
the Borrower, the Lenders and Issuers party thereto, Citicorp USA, Inc., as
administrative agent for the Lenders and Issuers (the "Administrative Agent"),
Fleet Capital Corporation and The CIT Group/Business Credit, Inc., as
Documentation Agents, Heller Financial, Inc. and GMAC Business Credit, LLC, as
Syndication Agents, Fuji Bank, Limited, as Co-Arranger, Salomon Smith Barney
Inc., as Sole Book Manager and Sole Lead Arranger.

            This opinion is rendered to you pursuant to Section 3.1(d) of the
Credit Agreement. Capitalized terms defined in the Credit Agreement, used
herein, and not otherwise defined herein, shall have the meanings given them in
the Credit Agreement.

            In so acting, we have examined originals or copies (certified or
otherwise identified to our satisfaction) of the following documents:

1.    the Credit Agreement;

2.    the Revolving Credit Notes issued by the Borrower on the date hereof;

3.    the Pledge and Security Agreement executed by each of the Loan Parties;

4.    the Guaranty executed by each of the Loan Parties (other than the
      Borrower);

5.    the Lien Subordination Agreement;

<PAGE>

6.    the financing statements on Form UCC-1, each naming a Loan Party as debtor
      and the Administrative Agent as secured party (the "Financing Statements")
      to be filed in the Uniform Commercial Code Filing Offices in the
      jurisdictions listed on Schedule I hereto (each a "Relevant
      Jurisdiction").

The agreements specified in clauses (1) through (6) above are collectively
referred to as the "Agreements".

            In addition, we have examined such corporate records, agreements,
documents and other instruments, and such certificates or comparable documents
of public officials and of officers and representative of the Loan Parties, and
have made such inquiries of such officers and representatives, as we have deemed
relevant and necessary as a basis for the opinions hereinafter set forth.

            In such examination, we have assumed the genuineness of all
signatures, the legal capacity of all natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified, conformed or photostatic copies and
the authenticity of the originals of such latter documents. As to all questions
of fact material to these opinions that have not been independently established,
we have relied upon certificates or comparable documents of officers and
representatives of the Loan Parties and upon the representations and warranties
of the Loan Parties contained in the Agreements.

            Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that:

                  A. Each Loan Party is a corporation validly existing and in
      good standing under the law of the State of Delaware and has all requisite
      corporate power and authority to own, lease and operate its properties and
      to carry on its business as now being conducted.

                  B. Each Loan Party is duly qualified to transact business and
      is in good standing as a foreign corporation in each jurisdiction set
      forth under its name on Schedule II hereto.

                  C. Each Loan Party has all requisite corporate power and
      authority to execute, deliver and perform the Agreements to which it is a
      party. The execution, delivery and performance by each Loan Party of the
      Agreements to which it is a party have been duly authorized by all
      necessary corporate action on the part of such Loan Party. Each Loan Party
      has duly executed and delivered the Agreements to which it is a party and
      such Agreements constitute the legal, valid and binding obligations of
      such Loan Party, enforceable against such Loan Party in accordance with
      their respective terms, subject to applicable bankruptcy, insolvency,
      fraudulent conveyance, reorganization, moratorium and similar laws
      affecting creditors' rights and remedies generally, and subject, as to
      enforceability, to general principles of

                                        2

<PAGE>

      equity, including principles of commercial reasonableness, good faith and
      fair dealing (regardless of whether enforcement is sought in a proceeding
      at law or in equity).

                  D. The execution, delivery and performance by each Loan Party
      of the Agreements to which it is a party will not conflict with,
      constitute a default under or violate (i) any of the terms, conditions or
      provisions of the Constituent Documents of such Loan Party, (ii) any of
      the terms, conditions or provisions of any material Contractual Obligation
      of such Loan Party of which we are aware, (iii) any New York, Delaware
      corporate or federal Requirement of Law or (iv) any judgment, writ,
      injunction, decree, order or ruling of any court or Governmental Authority
      of which we are aware binding on such Loan Party.

                  E. No consent, approval, waiver, license or authorization or
      other action by or filing with any New York, Delaware or federal
      Governmental Authority is required in connection with the execution,
      delivery or performance by any Loan Party of the Agreements to which it is
      a party except for the filing of financing statements referred to below.

                  F. The borrowings by and other financial accommodations
      provided to the Borrower under the Agreements and the application of
      proceeds thereof as provided in the Credit Agreement will not violate
      Regulation T, U or X of the Federal Reserve Board.

                  G. Neither the Borrower nor any other Loan Party is an
      "investment company" within the meaning of the Investment Company Act of
      1940, as amended, or a "holding company" or a "subsidiary company" of a
      "holding company" within the meaning of the Public Utility Holding Company
      Act of 1935, as amended.

                  H. To our knowledge, there is no action, suit, proceeding,
      governmental investigation or arbitration, at law or in equity or before
      any Governmental Authority, pending or overtly threatened against any Loan
      Party (i) with respect to any Agreement or challenging any of the
      Lenders', the Issuers' or the Administrative Agent's rights or remedies
      thereunder or (ii) which, if adversely determined, could materially
      adversely affect the ability of any Loan Party to perform its obligations
      under the Agreements to which it is a party.

                  I. All of the outstanding shares of the Pledged Stock (as
      defined in the Pledge and Security Agreement) of each Subsidiary of the
      Borrower (each an "Issuing Subsidiary") is (i) owned of record and, to our
      knowledge, beneficially by the Borrower or another Loan Party, free and
      clear of all adverse claims, (ii) are duly authorized, validly issued,
      fully paid and nonassessable, and (iii) have not been issued in violation
      of any preemptive rights granted by law or the Constituent Documents of
      such Issuing Subsidiary.

                  (a) The Pledge and Security Agreement creates in favor of the
            Administrative Agent, as security for each Loan Party's Secured
            Obligations, a

                                        3

<PAGE>

            valid first priority security interest in all of the right, title
            and interest of such Loan Party in the Collateral, which security
            interest, assuming the filing of the applicable Financing Statements
            in the filing offices of the Secretary of State of Delaware, will be
            duly perfected to the extent perfection of a security interest in
            such Collateral may be perfected by the filing of a financing
            statement under the Uniform Commercial Code in effect in the State
            of Delaware.

                  (b) Assuming delivery and continued possession in New York by
            the Administrative Agent of (i) certificates representing the
            Pledged Stock, together with stock powers properly executed in blank
            with respect thereto, and (ii) the Pledged Notes duly indorsed in
            favor of the Administrative Agent or in blank, the Pledge and
            Security Agreement creates a valid and duly perfected lien on and
            security interest in the Pledged Stock and the Pledged Notes, as
            security for the Secured Obligations, which is free of any adverse
            claim.

                  The opinion in subparagraph (a) is subject to the following
      exceptions:

                  (i) to the extent that perfection of a lien or security
      interest in any Collateral is governed by the law of any jurisdiction
      other than the States of New York and Delaware, we express no opinion;

                  (ii) that with respect to any Collateral which is or may
      become fixtures (within the meaning of Section 9-313 of the Uniform
      Commercial Code in effect in the State of New York (the "UCC")) we express
      no opinion; and

                  (iii) that with respect to transactions excluded from Article
      9 of the UCC by Section 9-104 thereof, we express no opinion.

                  The opinion set forth in subparagraph (b) is subject to the
      following exceptions and assumption:

                  (i) that with respect to (i) federal tax liens accorded
      priority under law and (ii) liens created under Title IV of the Employee
      Retirement Income Security Act of 1974, as amended, which are properly
      filed after the date hereof, we express no opinion as to the relative
      priority of such liens and the security interests created by the Pledge
      and Security Agreement in the Pledged Stock and the Pledged Notes;

                  (ii) that with respect to any claim in favor of any state or
      any of its respective agencies, authorities, municipalities or political
      subdivisions which claim is given lien status and/or priority under any
      law of such state, we express no opinion as to the relative priority of
      such liens and the security interests created by the Pledge and Security
      Agreement in the Pledged Stock and the Pledged Notes; and

                  (iii) we have assumed that with respect to the Pledged Stock
      the Administrative Agent was without notice of any adverse claim (as such
      phrase is defined in Section 8-102 of the UCC) and that with respect to
      the Pledged Notes the

                                        4

<PAGE>

      Administrative Agent acted in good faith and is unaware of any defense to
      payment thereof.

                  In addition, the opinions in subparagraphs (a) and (b) are
      subject to Section 552 of Title 11 of the United States Code (the
      "Bankruptcy Code") with respect to any Collateral acquired by any Loan
      Party subsequent to the commencement of a case against or by such Loan
      Party under the Bankruptcy Code.

                  The opinions expressed herein are rendered solely for your
      benefit in connection with the transactions described herein. This opinion
      may not be used or relied upon by any other person, nor may this letter or
      any copies thereof be furnished to a third party, filed with a
      governmental agency, quoted, cited or otherwise referred to without our
      prior written consent, other than to bank regulatory authorities or
      permitted assigns of any Lender, and except as required by any
      Governmental Authority or pursuant to legal process.

                                        Very truly yours,
