                 5.55% Senior Notes, Series A, due June 19, 2023
                 4.91% Senior Notes, Series B, due June 19, 2018
                 5.55% Senior Notes, Series C, due June 19, 2013

         This SUBSIDIARY GUARANTEE dated as of June 19, 2003 (the or this
"Guarantee") is entered into on a joint and several basis by the undersigned,
together with any entity which may become a party hereto by execution and
delivery of a Subsidiary Guarantee Supplement in substantially the form set
forth as EXHIBIT A hereto (a "Guarantee Supplement") (which parties are
hereinafter referred to individually as a "Guarantor" and collectively as the
"Guarantors").

                                    RECITALS

          A. Each Guarantor is a subsidiary or affiliate of NRP (OPERATING) LLC,
a Delaware limited liability company (the "Company").

          B. In order to reduce bank borrowing and for general limited liability
company purposes, the Company has entered into those certain separate Note
Purchase Agreements each dated as of June 19, 2003 (the "Note Purchase
Agreements") between the Company and each of the purchasers named on Schedule A
thereto (the "Initial Note Purchasers"; the Initial Note Purchasers, together
with their successors, assigns or any other future holder of the Notes (as
defined below), the "Holders"), providing for, inter alia, the issue and sale by
the Company to the Initial Note Purchasers of up to $175,000,000 aggregate
principal amount of its (i) 5.55% Senior Notes, Series A, due June 19, 2023,
(ii) 4.91% Senior Notes, Series B, due June 19, 2018 and (iii) 5.55% Senior
Notes, Series C, due June 19, 2013 (collectively, the "2003 Notes," and such
2003 Notes together with all other notes issued under the Note Purchase
Agreements, the "Notes").

          C. The Holders have required as a condition to their purchase of the
Notes that the Company cause the undersigned to enter into this Guarantee and
cause each entity that becomes a Subsidiary after June 19, 2003 to enter into a
Guarantee Supplement, in each case as security for the Notes, and the Company
has agreed to cause the undersigned to execute this Guarantee and to cause such
Subsidiaries to execute a Guarantee Supplement, in each case in order to induce
the Initial Note Purchasers to purchase the Notes and thereby benefit the
Company and its Subsidiaries by providing funds to reduce bank borrowing and for
general limited liability company purposes.

          D. Each of the Guarantors will derive substantial direct and indirect
benefit from the sale of the Notes to the Initial Note Purchasers.

          NOW, THEREFORE, as required by Section 4.11 of the Note Purchase
Agreements and in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency whereof are hereby acknowledged, each
Guarantor does hereby covenant and agree, jointly and severally, as follows:

<PAGE>

SECTION 1.           DEFINITIONS.

         Capitalized terms used herein shall have the meanings set forth in the
Note Purchase Agreements unless herein defined or the context shall otherwise
require.

SECTION 2.           GUARANTEE OF NOTES AND NOTE PURCHASE AGREEMENTS.

         (a) Each Guarantor jointly and severally does hereby irrevocably,
absolutely and unconditionally guarantee unto the Holders: (1) the full and
prompt payment of the principal of, premium, if any, and interest on the Notes
from time to time outstanding, as and when such payments shall become due and
payable whether by lapse of time, upon redemption or prepayment, by extension or
by acceleration or declaration or otherwise (including (to the extent legally
enforceable) interest due on overdue payments of principal, premium, if any, or
interest at the rate set forth in the Notes) in Federal or other immediately
available funds of the United States of America which at the time of payment or
demand therefor shall be legal tender for the payment of public and private
debts, (2) the full and prompt performance and observance by the Company of each
and all of the obligations, covenants and agreements required to be performed or
owed by the Company under the terms of the Notes and the Note Purchase
Agreements and (3) the full and prompt payment, upon demand by any Holder of all
costs and expenses, legal or otherwise (including reasonable attorneys' fees),
if any, as shall have been expended or incurred in the enforcement of any
rights, privileges or liabilities in favor of the Holders under or in respect of
the Notes and the Note Purchase Agreements or under this Guarantee or in any
consultation or action in connection therewith or herewith.

         (b) The liability of each Guarantor under this Guarantee shall not
exceed an amount equal to a maximum amount as will, after giving effect to such
maximum amount and all other liabilities of such Guarantor, contingent or
otherwise, result in the obligations of such Guarantor hereunder not
constituting a fraudulent transfer, obligation or conveyance.

SECTION 3.           GUARANTEE OF PAYMENT AND PERFORMANCE.

         This is a guarantee of payment and performance and each Guarantor
hereby waives, to the fullest extent permitted by law, any right to require that
any action on or in respect of any Note or the Note Purchase Agreements be
brought against the Company or any other Person or that resort be had to any
direct or indirect security for the Note Purchase Agreements or any other
remedy. Any Holder may, at its option, proceed hereunder against any Guarantor
in the first instance to collect monies when due, the payment of which is
guaranteed hereby, without first proceeding against the Company or any other
Person and without first resorting to any direct or indirect security for the
Notes or for this Guarantee or any other remedy. The liability of each Guarantor
hereunder shall in no way be affected or impaired by any acceptance by any
Holder of any direct or indirect security for, or other guaranties of, any Debt,
liability or obligation of the Company or any other Person to any Holder or by
any failure, delay, neglect or omission by any Holder to realize upon or protect
any such guarantees, Debt, liability or obligation or any notes or other
instruments evidencing the same or any direct or indirect security therefor or
by any approval, consent, waiver, or other action taken, or omitted to be taken
by any such Holder.

                                      -2-

         The covenants and agreements on the part of the Guarantors herein
contained shall take effect as joint and several covenants and agreements, and
references to the Guarantors shall take effect as references to each of them and
none of them shall be released from liability hereunder by reason of the
guarantee ceasing to be binding as a continuing security on any other of them.

SECTION 4.           GENERAL PROVISIONS RELATING TO THE GUARANTEE.

         (a) Each Guarantor hereby consents and agrees that any Holder or
Holders from time to time, with or without any further notice to or assent from
any other Guarantor may, without in any manner affecting the liability of any
Guarantor under this Guarantee, and upon such terms and conditions as any such
Holder or Holders may deem advisable:

                   (1) extend in whole or in part (by renewal or otherwise),
         modify, change, compromise, release or extend the duration of the time
         for the performance or payment of any Debt, liability or obligation of
         the Company or of any other Person secondarily or otherwise liable for
         any Debt, liability or obligations of the Company on the Notes, or
         waive any Default or Event of Default with respect thereto, or waive,
         modify, amend or change any provision of any other agreement or waive
         this Guarantee; or

                   (2) sell, release, surrender, modify, impair, exchange or
         substitute any and all property, of any nature and from whomsoever
         received, held by, or for the benefit of, any such Holder as direct or
         indirect security for the payment or performance of any Debt, liability
         or obligation of the Company or of any other Person secondarily or
         otherwise liable for any Debt, liability or obligation of the Company
         on the Notes; or

                   (3) settle, adjust or compromise any claim of the Company
         against any other Person secondarily or otherwise liable for any Debt,
         liability or obligation of the Company on the Notes.

         Each Guarantor hereby ratifies and confirms any such extension,
renewal, change, sale, release, waiver, surrender, exchange, modification,
amendment, impairment, substitution, settlement, adjustment or compromise and
that the same shall be binding upon it, and hereby waives, to the fullest extent
permitted by law, any and all defenses, counterclaims or offsets which it might
or could have by reason thereof, it being understood that such Guarantor shall
at all times be bound by this Guarantee and remain liable hereunder.

         (b) Each Guarantor hereby waives, to the fullest extent permitted by
law:

                   (1) notice of acceptance of this Guarantee by the Holders or
         of the creation, renewal or accrual of any liability of the Company,
         present or future, or of the reliance of such Holders upon this
         Guarantee (it being understood that every Debt, liability and
         obligation described in SECTION 2 hereof shall conclusively be presumed
         to have been created, contracted or incurred in reliance upon the
         execution of this Guarantee);

                                      -3-

<PAGE>

                   (2) demand of payment by any Holder from the Company or any
         other Person indebted in any manner on or for any of the Debt,
         liabilities or obligations hereby guaranteed; and

                   (3) presentment for the payment by any Holder or any other
         Person of the Notes or any other instrument, protest thereof and notice
         of its dishonor to any party thereto and to such Guarantor.

         The obligations of each Guarantor under this Guarantee and the rights
of any Holder to enforce such obligations by any proceedings, whether by action
at law, suit in equity or otherwise, shall not be subject to any reduction,
limitation, impairment or termination, whether by reason of any claim of any
character whatsoever or otherwise and shall not be subject to any defense,
set-off, counterclaim (other than any compulsory counterclaim), recoupment or
termination whatsoever.

         (c) The obligations of the Guarantors hereunder shall be binding upon
the Guarantors and their successors and assigns, and shall remain in full force
and effect irrespective of:

                   (1) the genuineness, validity, regularity or enforceability
         of the Notes or the Note Purchase Agreements or any of the terms of any
         thereof, the continuance of any obligation on the part of the Company
         or any other Person on or in respect of the Notes or under the Note
         Purchase Agreements or any other agreement or the power or authority or
         the lack of power or authority of the Company to issue the Notes or the
         Company to execute and deliver the Note Purchase Agreements or any
         other agreement or of any Guarantor to execute and deliver this
         Guarantee or to perform any of its obligations hereunder or the
         existence or continuance of the Company or any other Person as a legal
         entity; or

                   (2) any default, failure or delay, willful or otherwise, in
         the performance by the Company, any Guarantor or any other Person of
         any obligations of any kind or character whatsoever under the Notes,
         the Note Purchase Agreements, this Guarantee or any other agreement; or

         the Company, any Guarantor or any other Person of its obligations under
         the Notes, the Note Purchase Agreements, this Guarantee or any other

<PAGE>

         any of the assets of the Company, any Guarantor or any other Person to
         any other Person, or any change in the ownership of any shares or
         partnership interests of the Company, any Guarantor or any other
         Person; or

                  (12) any defense whatsoever that: (i) the Company or any other
         Person might have to the payment of the Notes (principal, premium, if
         any, or interest), other than payment thereof in Federal or other
         immediately available funds, or (ii) the Company or any other Person
         might have to the performance or observance of any of the provisions of
         the Notes, the Note Purchase Agreement or any other agreement, whether
         through the satisfaction or purported satisfaction by the Company or
         any other Person of its debts due to any cause such as bankruptcy,
         insolvency, receivership, merger, consolidation, reorganization,
         dissolution, liquidation, winding-up or otherwise, other than the
         defense of indefeasible payment in full in cash of the Notes; or

                  (13) any act or failure to act with regard to the Notes, the
         Note Purchase Agreements, this Guarantee or any other agreement or
         anything which might vary the risk of any Guarantor or any other
         Person; or

                  (14) any other circumstance which might otherwise constitute a
         defense available to, or a discharge of, any Guarantor or any other
         Person in respect of the obligations of any Guarantor or other Person
         under this Guarantee or any other agreement, other than the defense of
         indefeasible payment in full in cash of the Notes;

provided that the specific enumeration of the above-mentioned acts, failures or
omissions shall not be deemed to exclude any other acts, failures or omissions,
though not specifically mentioned above, it being the purpose and intent of this
Guarantee and the parties hereto that the obligations of each Guarantor shall be
absolute and unconditional and shall not be discharged, impaired or varied
except by the payment of the principal of, premium, if any, and interest on the
Notes in accordance with their respective terms whenever the same shall become
due and payable as in the Notes provided, at the place specified in and all in
the manner and with the effect provided in the Notes and the Note Purchase
Agreements, as each may be amended or modified from time to time. Without
limiting the foregoing, it is understood that repeated and successive demands
may be made and recoveries may be had hereunder as and when, from time to time,
the Company shall default under or in respect of the terms of the Notes or the
Note Purchase Agreements and that notwithstanding recovery hereunder for or in
respect of any given default or defaults by the Company under the Notes or the
Note Purchase Agreements, this Guarantee shall remain in full force and effect
and shall apply to each and every subsequent default.

         (d) All rights of any Holder may be transferred or assigned at any time
in accordance with the Note Purchase Agreements and shall be considered to be
transferred or assigned at any time or from time to time upon the transfer of
such Note in accordance with the Note Purchase Agreements whether with or
without the consent of or notice to the Guarantors under this Guarantee.

         (e) To the extent of any payments made under this Guarantee, the
Guarantors shall be subrogated to the rights of the Holder or Holders upon whose
Notes such payment was made, but

                                      -6-

<PAGE>

each Guarantor covenants and agrees that such right of subrogation shall be
junior and subordinate in right of payment to the prior indefeasible final
payment in cash in full of all amounts due and owing by the Company with respect
to the Notes and the Note Purchase Agreements and by the Guarantors under this
Guarantee, and the Guarantors shall not take any action to enforce such right of
subrogation, and the Guarantors shall not accept any payment in respect of such
right of subrogation, until all amounts due and owing by the Company under or in
respect of the Notes and the Note Purchase Agreements and all amounts due and
owing by the Guarantors hereunder have indefeasibly been paid in cash in full.
If any amount shall be paid to any Guarantor in violation of the preceding
sentence at any time prior to the indefeasible payment in cash in full of the
Notes and all other amounts payable under the Notes, the Note Purchase
Agreements and this Guarantee, such amount shall be held in trust for the
benefit of the Holders and shall forthwith be paid to the Holders to be credited
and applied to the amounts due or to become due with respect to the Notes and
all other amounts payable under the Note Purchase Agreements and this Guarantee,
whether matured or unmatured.

         (f) To the extent of any payments made under this Guarantee, each
Guarantor making such payment shall have a right of contribution from the other
Guarantors, but such Guarantor covenants and agrees that such right of
contribution shall be subordinate in right of payment to the rights of the
Holders for which full payment has not been made or provided for and, to that
end, such Guarantor agrees not to claim or enforce any such right of
contribution unless and until all of the Notes and all other sums due and
payable under the Note Purchase Agreements have been fully and irrevocably paid
and discharged.

         (g) Each Guarantor agrees that to the extent the Company or any other
Person makes any payment on any Note, which payment or any part thereof is
subsequently invalidated, voided, declared to be fraudulent or preferential, set
aside, recovered, rescinded or is required to be retained by or repaid to a
trustee, receiver, or any other Person under any bankruptcy code, common law, or
equitable cause, then and to the extent of such payment, the obligation or the
part thereof intended to be satisfied shall be revived and continued in full
force and effect with respect to the Guarantors' obligations hereunder, as if
said payment had not been made. The liability of the Guarantors hereunder shall
not be reduced or discharged, in whole or in part, by any payment to any Holder
from any source that is thereafter paid, returned or refunded in whole or in
part by reason of the assertion of a claim of any kind relating thereto,
including, but not limited to, any claim for breach of contract, breach of
warranty, preference, illegality, invalidity, or fraud asserted by any account
debtor or by any other Person.

         (h) No Holder shall be under any obligation: (1) to marshal any assets
in favor of the Guarantors or in payment of any or all of the liabilities of the
Company under or in respect of the Notes or the obligations of the Guarantors
hereunder or (2) to pursue any other remedy that the Guarantors may or may not
be able to pursue themselves and that may lighten the Guarantors' burden, any
right to which each Guarantor hereby expressly waives.

                                      -7-

other legal entity and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the
failure to be so qualified or in good standing would not, individually or in the
aggregate, reasonably be expected to have a material adverse effect on (1) the
business, operations, affairs, financial condition, assets or properties of the
Company and its subsidiaries, taken as a whole, or (2) the ability of such
Guarantor to perform its obligations under this Guarantee, or (3) the validity
or enforceability of this Guarantee (herein in this SECTION 5, a "Material
Adverse Effect"). Such Guarantor has the power and authority to own or hold
under lease the properties it purports to own or hold under lease, to transact
the business it transacts and proposes to transact, to execute and deliver this
Guarantee and to perform the provisions hereof.

         (b) This Guarantee has been duly authorized by all necessary action on
the part of such Guarantor, and this Guarantee constitutes a legal, valid and
binding obligation of such Guarantor enforceable against such Guarantor in
accordance with its terms, except as such enforceability may be limited by (1)
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting the enforcement of creditors' rights generally and (2) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

         (c) The execution, delivery and performance by such Guarantor of this
Guarantee will not (1) contravene, result in any breach of, or constitute a
default under, or result in the creation of any Lien in respect of any property
of such Guarantor or any of its Subsidiaries under any indenture, mortgage, deed
of trust, loan, purchase or credit agreement, lease, charter document or by-law,
or any other agreement or instrument to which such Guarantor or any of its
Subsidiaries is bound or by which such Guarantor or any of its Subsidiaries or
any of their respective properties may be bound or affected, (2) conflict with
or result in a breach of any of the terms, conditions or provisions of any
order, judgment, decree, or ruling of any court, arbitrator or governmental
authority applicable to such Guarantor or any of its Subsidiaries or (3) violate
any provision of any statute or other rule or regulation of any Governmental
Authority applicable to the such Guarantor or any of its Subsidiaries.

         (d) No consent, approval or authorization of, or registration, filing
or declaration with, any governmental authority is required in connection with
the execution, delivery or performance by such Guarantor of this Guarantee.

         (e) Such Guarantor is solvent, has capital not unreasonably small in
relation to its business or any contemplated or undertaken transaction and has
assets having a value both at fair valuation and at present fair salable value
greater than the amount required to pay its debts as they become due and greater
than the amount that will be required to pay its probable liability on its
existing debts as they become absolute and matured. Such Guarantor does not
intend to incur

                                      -8-
<PAGE>

debts beyond its ability to pay such debts as they become due. Such Guarantor
will not be rendered insolvent by the execution and delivery of, this Guarantee
and, on a consolidated basis with the Company, will not be rendered insolvent.
Such Guarantor does not intend to hinder, delay or defraud its creditors by or
through the execution and delivery of, or performance of its obligations under,
this Guarantee.

         (f) Each representation contained in Section 5 of the Note Purchase
Agreements is true and correct to the extent applicable to such Guarantor.

SECTION 6.           GUARANTOR COVENANTS.

         (a) Each Guarantor agrees to comply with the terms and provisions of
Sections 9 and 10 of the Note Purchase Agreements, insofar as such provisions
apply to such Guarantor, as if said Sections were set forth herein in full.

         (b) In addition to the foregoing, no Guarantor shall consolidate with
or merge with any other corporation, limited liability company or limited
partnership (other than the Company or another Guarantor) or convey, transfer or
lease substantially all of its assets in a single transaction or series of
transactions to any Person unless:

                   (i) the successor formed by such consolidation or the
         survivor of such merger or the Person that acquires by conveyance,
         transfer or lease substantially all of the assets of such Guarantor as
         an entirety, as the case may be, shall be a solvent corporation,
         limited liability company or limited partnership organized and existing
         under the laws of the United States or any State thereof (including the
         District of Columbia), and, if such Guarantor is not such corporation,
         limited liability company or limited partnership (i) such corporation,
         limited liability company or limited partnership shall have executed
         and delivered to each holder of any Notes its assumption of the due and
         punctual performance and observance of each covenant and condition of
         this Guarantee and (ii) shall have caused to be delivered to each
         holder of any Notes an opinion of nationally recognized independent
         counsel, or other independent counsel reasonably satisfactory to the
         Required Holders, to the effect that all agreements or instruments
         effecting such assumption are enforceable in accordance with their
         terms and comply with the terms hereof;

                  (ii) immediately after giving effect to such transaction, (A)
         no Default or Event of Default shall have occurred and be continuing;
         and (B) the Company would be able to incur at least $1.00 of additional
         Debt under the terms of Section 10.6(a)(iii) of the Note Purchase
         Agreement.

No such conveyance, transfer or lease of substantially all of the assets of a
Guarantor shall have the effect of releasing such Guarantor or any successor
corporation, limited liability company or limited partnership that shall
theretofore have become such in the manner prescribed in this Section 6 from its
liability under this Guarantee.

SECTION 7.           GOVERNING LAW.

         (a) THIS GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE THEREIN.

         (b) Each Guarantor hereby (i) irrevocably submits and consents to the
jurisdiction of the federal court located in New York (or, if such court lacks
jurisdiction, the State courts located therein), and irrevocably agrees that all
actions or proceedings relating to this Guarantee may be litigated in such
courts, and (ii) waives any objection which it may have based on improper venue
or forum non conveniens to the conduct of any proceeding in any such court and
waives personal service of any and all process upon it, and (iii) consents that
all such service of process be made by delivery to it at the address of such
Person set forth in SECTION 9 below. Nothing contained in this section shall
affect the right of any Holder to serve legal process in any other manner
permitted by law or to bring any action or proceeding in the courts of any
jurisdiction against a Guarantor or to enforce a judgment obtained in the courts
of any other jurisdiction.

         (c) THE PARTIES HERETO WAIVE ANY RIGHT TO HAVE A JURY PARTICIPATE IN
RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN
THEM ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS GUARANTEE, THE
NOTES, THE NOTE PURCHASE AGREEMENTS OR ANY OTHER INSTRUMENT, DOCUMENT OR
AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS
RELATED HERETO. THE PARTIES HERETO HEREBY AGREE AND CONSENT THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY
AND THAT ANY OF THEM MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
GUARANTEE WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

SECTION 8.           AMENDMENTS, WAIVERS AND CONSENTS.

         (a) This Guarantee may be amended, and the observance of any term
hereof may be waived (either retroactively or prospectively), with (and only
with) the written consent of each Guarantor and the Holders.

         (b) The Guarantors will provide each Holder (irrespective of the amount
of Notes then owned by it) with sufficient information, sufficiently far in
advance of the date a decision is required, to enable such Holder to make an
informed and considered decision with respect to any proposed amendment, waiver
or consent in respect of any of the provisions hereof. The Guarantors will
deliver executed or true and correct copies of each amendment, waiver or consent
effected pursuant to the provisions of this SECTION 8 to each Holder promptly
following the date on which it is executed and delivered by, or receives the
consent or approval of, the Required Holders.

         (c) The Company will not directly or indirectly pay or cause to be paid
any remuneration, whether by way of fee or otherwise, or grant any security, to
any Holder as consideration for or as an inducement to the entering into by any
Holder of any waiver or amendment of any of the terms and provisions hereof
unless such remuneration is concurrently

                                      -10-

<PAGE>

paid, or security is concurrently granted, on the same terms, ratably to each
Holder even if such Holder did not consent to such waiver or amendment.

         (d) Any amendment or waiver consented to as provided in this SECTION 8
applies equally to all Holders and is binding upon them and upon each future
holder and upon the Guarantors. No such amendment or waiver will extend to or
affect any obligation, covenant or agreement not expressly amended or waived or
impair any right consequent thereon. No course of dealing between the Guarantors
and any Holder nor any delay in exercising any rights hereunder shall operate as
a waiver of any rights of any Holder. As used herein, the term "this Guarantee"
and references thereto shall mean this Guarantee as it may from time to time be
amended or supplemented.

         (e) Solely for the purpose of determining whether the Holders of the
requisite percentage of the aggregate principal amount of Notes then outstanding
approved or consented to any amendment, waiver or consent to be given under this
Guarantee, Notes directly or indirectly owned by any Guarantor, the Company or
any of their respective subsidiaries or Affiliates shall be deemed not to be
outstanding.

SECTION 9.           NOTICES.

         All notices and communications provided for hereunder shall be in
writing and sent (a) by telefacsimile if the sender on the same day sends a
confirming copy of such notice by a recognized overnight delivery service
(charges prepaid), or (b) by registered or certified mail with return receipt
requested (postage prepaid), or (c) by a recognized overnight delivery service
(with charges prepaid). Any such notice must be sent:

                   (1) if to any Holder or such Holder's nominee, to such Holder
         or such Holder's nominee at the address specified for such
         communications in Schedule A to the Note Purchase Agreements, or at
         such other address as such Holder or such Holder's nominee shall have
         specified to the Company in writing,

                   (2) if to any Guarantor, to such Guarantor c/o NRP
         (Operating) LLC at its address set forth at the beginning of the Note
         Purchase Agreement to the attention of Dwight Dunlap, Chief Financial
         Officer, or at such other address as such Guarantor shall have
         specified to the Holders in writing.

Notices under this SECTION 9 will be deemed given only when actually received.

SECTION 10.          MISCELLANEOUS.

         (a) No remedy herein conferred upon or reserved to any Holder is
intended to be exclusive of any other available remedy or remedies, but each and
every such remedy shall be cumulative and shall be in addition to every other
remedy given under this Guarantee now or hereafter existing at law or in equity.
No delay or omission to exercise any right or power accruing upon any default,
omission or failure of performance hereunder shall impair any such right or
power or shall be construed to be a waiver thereof but any such right or power
may be

                                      -11-

<PAGE>

exercised from time to time and as often as may be deemed expedient. In order to
entitle any Holder to exercise any remedy reserved to it under this Guarantee,
it shall not be necessary for such Holder to physically produce its Note in any
proceedings instituted by it or to give any notice, other than such notice as
may be herein expressly required.

         (b) The Guarantors will pay all sums becoming due under this Guarantee
by the method and at the address specified in the Note Purchase Agreements, or
by such other method or at such other address as any Holder shall have from time
to time specified to the Guarantors in writing for such purpose, without the
presentation or surrender of this Guarantee or any Note.

         (c) Any provision of this Guarantee that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

         (d) If the whole or any part of this Guarantee shall be now or
hereafter become unenforceable against any one or more of the Guarantors for any
reason whatsoever or if it is not executed by any one or more of the Guarantors,
this Guarantee shall nevertheless be and remain fully binding upon and
enforceable against each other Guarantor as if it had been made and delivered
only by such other Guarantors.

         (e) This Guarantee shall be binding upon each Guarantor and its
successors and assigns and shall inure to the benefit of each Holder and its
successors and assigns so long as its Notes remain outstanding and unpaid.

         (f) This Guarantee may be executed in any number of counterparts, each
of which shall be an original but all of which together shall constitute one
instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.

SECTION 11.          INDEMNITY.

         To the fullest extent of applicable law, each Guarantor shall indemnify
and save each Holder harmless from and against any losses (other than any such
losses created as a result of the gross negligence or willful misconduct of any
Holder) which may arise by virtue of any of the obligations hereby guaranteed
being or becoming for any reason whatsoever in whole or in part void, voidable,
contrary to law, invalid, ineffective or otherwise unenforceable by the Holder
or any of them in accordance with its terms (all of the foregoing collectively,
an "Indemnifiable Circumstance"). For greater certainty, these losses shall
include without limitation all obligations hereby guaranteed which would have
been payable by the Company but for the existence of an Indemnifiable
Circumstance; provided, however, that the extent of the Guarantor's aggregate
liability under this SECTION 11 shall not at any time exceed the amount (but for
any Indemnifiable Circumstance) otherwise guaranteed pursuant to SECTION 2.

                                      -12-

         pursuant to this Section 2.6 shall not exceed $75,000,000; (C) the
         Borrower, each Purchaser and/or each Increasing Lender shall have
         executed and delivered to the Administrative Agent a commitment and
         acceptance (the "Commitment and Acceptance") substantially in the form
         of Exhibit F hereto, and the Administrative Agent shall have accepted
         and executed the same, (D) if requested by the Purchaser and/or the
         Increasing Lenders, the Borrower shall have executed and delivered to
         the Administrative Agent a Note or Notes payable to the order of each
         Purchaser and/or each Increasing Lender, each such Note to be in the
         amount of such Purchaser's Commitment or such Increasing Lender's
         Commitment (as applicable), (E) the Guarantors shall have consented in
         writing to the new Commitments or increases in Commitments (as
         applicable) and shall have agreed that their Guaranty continue in full
         force and effect, and (F) the Borrower, each Purchaser and/or each
         Increasing Lender shall otherwise have executed and delivered such
         other instruments and documents as the Administrative

                                       15

<PAGE>

         Agent shall have reasonably requested in connection with such new
         Commitment or increase in the Commitment (as applicable). The form and
         substance of the documents required under clauses (C) through (F) above
         shall be reasonably acceptable to the Administrative Agent. The
         Administrative Agent shall provide prior written notice to all of the
         Lenders hereunder of the admission of any Purchaser or the increase in
         the Commitment of any Increasing Lender hereunder and shall furnish to
         each of the Lenders copies of the documents required under clause (C),
         (E) and (F) above.

                  (ii)     Upon the effective date of any increase in the
         Aggregate Commitment pursuant to the provisions hereof ("Increase
         Date"), which Increase Date shall be mutually agreed upon by the
         Borrower, each Purchaser, each Increasing Lender and the Administrative
         Agent, each Purchaser and/or Increasing Lender shall make a payment to
         the Administrative Agent in an amount sufficient, upon the application
         of such payments by all Purchasers and Increasing Lenders to the
         reduction of the Outstanding Credit Exposures of the Lenders (including
         the Increasing Lenders), to cause the Outstanding Credit Exposures of
         each Lender to be equal to each Lender's Pro Rata Share of the
         Aggregate Commitment as so increased. The Borrower hereby irrevocably
         authorizes each Purchaser and/or each Increasing Lender to fund to the
         Administrative Agent the payment required to be made pursuant to the
         immediately preceding sentence for application to the reduction of the
         Outstanding Credit Exposures of the Lenders, and each such payment
         shall constitute a Loan hereunder. If, as a result of the repayment of
         the Outstanding Credit Exposures provided for in this Section 2.6(ii),
         any payment of a Eurodollar Loan occurs on a day which is not the last
         day of the applicable Interest Period, the Borrower will pay to the
         Administrative Agent for the benefit of any of the Lenders (including
         any Increasing Lender to the extent of Eurodollar Loans held by such
         Increasing Lender prior to such Increase Date) holding a Eurodollar
         Loan any loss or cost incurred by such Lender resulting therefrom in
         accordance with Section 3.4. Upon the Increase Date, all Loans
         outstanding hereunder (including any Loans made by the Purchasers
         and/or Increasing Lenders on the Increase Date) shall be Floating Rate
         Loans, subject to the Borrower's right to convert the same to
         Eurodollar Loans on or after such date in accordance with the
         provisions of Section 2.10.

                  (iii)    Upon the Increase Date and the making of the Loans by
         the Purchasers and/or Increasing Lenders in accordance with the
         provisions of Section 2.6(ii), each Purchaser and/or each Increasing
         Lender shall also be deemed to have irrevocably and unconditionally
         purchased and received without recourse or warranty, from the Lenders
         immediately prior to the Increase Date, an undivided interest and
         participation in any Facility LC and Swing Line Advance, as applicable,
         then outstanding, ratably, such that each Lender (including each
         Purchaser) holds a participation interest in each such Facility LC and
         Swing Line Advance, as applicable, in proportion to such Lender's Pro
         Rata Share.

                  (iv)     Upon the notice by the Borrower to the Administrative
         Agent pursuant to Section 2.6(i) hereof, each of the then existing
         Lenders shall have the right (at its election) to increase its
         Commitment by an amount equal to such Lender's Pro Rata Share of the
         proposed increase in the Aggregate Commitment. If less than all of the
         proposed increase in Aggregate Commitment is elected by the existing
         Lenders, then any of the

                                       16

<PAGE>

         then existing Lenders shall have the right to increase its Commitment
         in an amount greater than such Lender's Pro Rata Share of the proposed
         increase in the Aggregate Commitment with the Administrative Agent's
         approval. In the event the sum of each Purchaser's Commitment and the
         increase in each Increasing Lender's Commitment is less than the
         requested increase in the Aggregate Commitment, the Borrower may elect
         to accept the increase in the Aggregate Commitment to be equal to such
         lesser amount. Notwithstanding anything to the contrary contained
         herein, the Administrative Agent shall not be liable for any failure to
         obtain Increasing Lenders or Purchasers hereunder or for any failure to
         increase the Aggregate Commitment by the amount so requested by the
         Borrower pursuant to Section 2.6(i).

                  (v)      Nothing contained herein shall constitute or
         otherwise be deemed to be a commitment or agreement on the part of any
         Lender to increase its Commitment hereunder at any time. No Lender
         (except only for itself) shall have the right to decline Borrower's
         request pursuant to Section 2.6(i) for an increase in the Aggregate
         Commitment.

         2.7.     Minimum Amount of Each Advance. Each Eurodollar Advance shall
be in the minimum amount of $1,000,000 (and in multiples of $100,000 if in
excess thereof), and each Floating Rate Advance shall be in the minimum amount
of $1,000,000 (and in multiples of $100,000 if in excess thereof); provided,
however, that any Floating Rate Advance may be in the amount of the Available
Aggregate Commitment.

         2.8.     Optional Principal Payments. The Borrower may from time to
time pay, without penalty or premium, all outstanding Floating Rate Advances,
or, in a minimum aggregate amount of $1,000,000 or any integral multiple of
$100,000 in excess thereof, any portion of the outstanding Floating Rate
Advances not later than 1:00 p.m. (Dallas time) upon prior written notice to the
Administrative Agent on the date of such prepayment. The Borrower may from time
to time pay, subject to the payment of any funding indemnification amounts
required by Section 3.4 but without penalty or premium, all outstanding
Eurodollar Advances, or, in a minimum aggregate amount of $1,000,000 or any
integral multiple of $100,000 in excess thereof, any portion of the outstanding
Eurodollar Advances upon three Business Days' prior notice to the Administrative
Agent.

         2.9.     Method of Selecting Types and Interest Periods for New
Advances. Except with respect to Swing Line Advances, the Borrower shall select
the Type of Advance and, in the case of each Eurodollar Advance, the Interest
Period applicable thereto from time to time. The Borrower shall give the
Administrative Agent irrevocable notice (a "Borrowing Notice") not later than
10:00 a.m. (Dallas time) at least one Business Day before the Borrowing Date of
each Floating Rate Advance and three Business Days before the Borrowing Date for
each Eurodollar Advance, specifying:

                  (i)      the Borrowing Date, which shall be a Business Day, of
         such Advance,

                  (ii)     the aggregate amount of such Advance,

                  (iii)    the Type of Advance selected, and

                                       17

<PAGE>

                  (iv)     in the case of each Eurodollar Advance, the Interest
         Period applicable thereto.

Not later than noon (Dallas time) on each Borrowing Date, each Lender shall make
available its Loan or Loans in funds immediately available in Dallas to the
Administrative Agent at its address specified pursuant to Article XIII. The
Administrative Agent will make the funds so received from the Lenders available
to the Borrower at the Administrative Agent's aforesaid address.

         2.10.    Conversion and Continuation of Outstanding Advances. Floating
Rate Advances shall continue as Floating Rate Advances unless and until such
Floating Rate Advances are converted into Eurodollar Advances pursuant to this
Section 2.10 or are repaid in accordance with Section 2.8. Each Eurodollar
Advance shall continue as a Eurodollar Advance until the end of the then
applicable Interest Period therefor, at which time such Eurodollar Advance shall
be automatically converted into a Floating Rate Advance unless (x) such
Eurodollar Advance is or was repaid in accordance with Section 2.8 or (y) the
Borrower shall have given the Administrative Agent a Conversion/Continuation
Notice (as defined below) requesting that, at the end of such Interest Period,
such Eurodollar Advance continue as a Eurodollar Advance for the same or another
Interest Period. Subject to the terms of Section 2.7, the Borrower may elect
from time to time to convert all or any part of a Floating Rate Advance (other
than Swing Line Advances) into a Eurodollar Advance. The Borrower shall give the
Administrative Agent irrevocable notice (a "Conversion/Continuation Notice") of
each conversion of a Floating Rate Advance into a Eurodollar Advance or
continuation of a Eurodollar Advance not later than 10:00 a.m. (Dallas time) at
least three Business Days prior to the date of the requested conversion or
continuation, specifying:

                  (i)      the requested date, which shall be a Business Day, of
         such conversion or continuation,

                  (ii)     the aggregate amount and Type of the Advance which is
         to be converted or continued, and

                  (iii)    the amount of such Advance which is to be converted
         into or continued as a Eurodollar Advance and the duration of the
         Interest Period applicable thereto.

         2.11.    Changes in Interest Rate, etc. Each Floating Rate Advance
shall bear interest on the outstanding principal amount thereof, for each day
from and including the date such Advance is made or is automatically converted
from a Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.10,
to but excluding the date it is paid or is converted into a Eurodollar Advance
pursuant to Section 2.10 hereof, at a rate per annum equal to the lesser of (a)
the Maximum Rate, or (b) the Floating Rate for such day. Changes in the rate of
interest on that portion of any Advance maintained as a Floating Rate Advance
will take effect simultaneously with each change in the Alternate Base Rate. If
at any time the Floating Rate shall exceed the Maximum Rate, thereby causing the
interest accruing on an Advance to be limited to the Maximum Rate, then any
subsequent reduction in the Floating Rate for such Advance shall not reduce the
rate of interest on such Advance below the Maximum Rate until the aggregate
amount of interest accrued on such Advance equals the aggregate amount of
interest which would have

                                       18

<PAGE>

accrued on such Advance if the Floating Rate had at all times been in effect.
Each Eurodollar Advance shall bear interest on the outstanding principal amount
thereof from and including the first day of the Interest Period applicable
thereto to (but not including) the last day of such Interest Period at the
interest rate determined by the Administrative Agent as applicable to such
Eurodollar Advance based upon the Borrower's selections under Sections 2.9 and
2.10 and otherwise in accordance with the terms hereof. No Interest Period may
end after the Facility Termination Date.

         2.12.    Rates Applicable After Default. Notwithstanding anything to
the contrary contained in Section 2.9 or 2.10, during the continuance of a
Default or Unmatured Default the Required Lenders may, at their option, by
notice to the Borrower, declare that no Advance may be made as, converted into
or continued as a Eurodollar Advance. During the continuance of a Default the
Required Lenders may, at their option, by notice to the Borrower, declare that
(i) each Eurodollar Advance shall bear interest for the remainder of the
applicable Interest Period at the rate otherwise applicable to such Interest
Period (but calculated as if the highest Applicable Margin was then in effect)
plus 2% per annum, (ii) each Floating Rate Advance shall bear interest at a rate
per annum equal to the Floating Rate in effect from time to time (but calculated
as if the highest Applicable Margin was then in effect) plus 2% per annum and
(iii) the LC Fee shall be calculated as if the highest Applicable Margin was
then in effect and increased by 2% per annum, provided that, during the
continuance of a Default under Section 7.6 or 7.7, the interest rates set forth
in clauses (i) and (ii) above and the increase in the LC Fee set forth in clause
(iii) above shall be applicable to all Credit Extensions without any election or
action on the part of the Administrative Agent or any Lender, subject in all
events to the limitations of the Maximum Rate.

         2.13.    Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Administrative Agent at the Administrative Agent's
address specified pursuant to Article XIII, or at any other Lending Installation
of the Administrative Agent specified in writing by the Administrative Agent to
the Borrower, by noon (local time) on the date when due and shall (except in the
case of Reimbursement Obligations for which the LC Issuer has not been fully
indemnified by the Lenders, or as otherwise specifically required hereunder) be
applied ratably by the Administrative Agent among the Lenders. Each payment
delivered to the Administrative Agent for the account of any Lender shall be
delivered promptly by the Administrative Agent to such Lender in the same type
of funds that the Administrative Agent received at its address specified
pursuant to Article XIII or at any Lending Installation specified in a notice
received by the Administrative Agent from such Lender. The Administrative Agent
is hereby authorized to charge the account of the Borrower maintained with Bank
One for each payment of principal, interest, Reimbursement Obligations and fees
as it becomes due hereunder. Each reference to the Administrative Agent in this
Section 2.13 shall also be deemed to refer, and shall apply equally, to the LC
Issuer, in the case of payments required to be made by the Borrower to the LC
Issuer pursuant to Section 2.20.6.

         2.14.    Noteless Agreement; Evidence of Indebtedness.

                  (i)      Each Lender shall maintain in accordance with its
         usual practice an account or accounts evidencing the indebtedness of
         the Borrower to such Lender

                                       19

<PAGE>

         resulting from each Loan made by such Lender from time to time,
         including the amounts of principal and interest payable and paid to
         such Lender from time to time hereunder.

                  (ii)     The Administrative Agent shall also maintain accounts
         in which it will record (a) the amount of each Loan made hereunder, the
         Type thereof and the Interest Period with respect thereto, (b) the
         amount of any principal or interest due and payable or to become due
         and payable from the Borrower to each Lender hereunder, (c) the
         original stated amount of each Facility LC and the amount of LC
         Obligations outstanding at any time, and (d) the amount of any sum
         received by the Administrative Agent hereunder from the Borrower and
         each Lender's share thereof.

                  (iii)    The entries maintained in the accounts maintained
         pursuant to clauses (i) and (ii) above shall be prima facie evidence of
         the existence and amounts of the Obligations therein recorded;
         provided, however, that the failure of the Administrative Agent or any
         Lender to maintain such accounts or any error therein shall not in any
         manner affect the obligation of the Borrower to repay the Obligations
         in accordance with their terms.

                  (iv)     Any Lender may request that its Loans under the
         Revolving Credit Facility be evidenced by a promissory note in
         substantially the form of Exhibit E (a "Note"). In such event, the
         Borrower shall prepare, execute and deliver to such Lender a Note
         payable to the order of such Lender in a form supplied by the
         Administrative Agent. Thereafter, the Loans evidenced by such Note and
         interest thereon shall at all times (including after any assignment
         pursuant to Section 12.3) be represented by one or more Notes payable
         to the order of the payee named therein or any assignee pursuant to
         Section 12.3, except to the extent that any such Lender or assignee
         subsequently returns any such Note for cancellation and requests that
         such Loans once again be evidenced as described in clauses (i) and (ii)
         above.

         2.15.    Telephonic Notices. The Borrower hereby authorizes the Lenders
and the Administrative Agent to extend, convert or continue Advances, effect
selections of Types of Advances and to transfer funds based on telephonic
notices made by any person or persons the Administrative Agent or any Lender in
good faith believes to be acting on behalf of the Borrower, it being understood
that the foregoing authorization is specifically intended to allow Borrowing
Notices and Conversion/Continuation Notices to be given telephonically. The
Borrower agrees to deliver promptly to the Administrative Agent a written
confirmation, if such confirmation is requested by the Administrative Agent or
any Lender, of each telephonic notice signed by an Authorized Officer. If the
written confirmation differs in any material respect from the action taken by
the Administrative Agent and the Lenders, the records of the Administrative
Agent and the Lenders shall govern absent manifest error.

         2.16.    Interest Payment Dates; Interest and Fee Basis. Interest
accrued on each Floating Rate Advance not including Swing Line Advances shall be
payable on each Payment Date, commencing with the first such date to occur after
the date hereof and at maturity. Interest accrued on each Eurodollar Advance
shall be payable on the last day of its applicable Interest Period, on any date
on which the Eurodollar Advance is prepaid, whether by acceleration or
otherwise, and at maturity. Interest accrued on each Eurodollar Advance having
an Interest

                                       20

<PAGE>

Period longer than three months shall also be payable on the last day of each
three-month interval during such Interest Period. Interest, commitment fees and
LC Fees shall be calculated for actual days elapsed on the basis of a 360-day
year. Interest shall be payable for the day an Advance is made but not for the
day of any payment on the amount paid if payment is received prior to noon
(local time) at the place of payment. If any payment of principal of or interest
on an Advance shall become due on a day which is not a Business Day, such
payment shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.

         2.17.    Notification of Advances, Interest Rates, Prepayments and
Commitment Reductions. Promptly after receipt thereof, the Administrative Agent
will notify each Lender of the contents of each Aggregate Commitment reduction
notice, Borrowing Notice, Conversion/Continuation Notice, and repayment notice
received by it hereunder. Promptly after notice from the LC Issuer, the
Administrative Agent will notify each Lender of the contents of each request for
issuance of a Facility LC hereunder. The Administrative Agent will notify each
Lender of the interest rate applicable to each Eurodollar Advance promptly upon
determination of such interest rate and will give each Lender prompt notice of
each change in the Alternate Base Rate.

         2.18.    Lending Installations. Each Lender may book its Loans and its
participation in any LC Obligations and the LC Issuer may book the Facility LCs
at any Lending Installation selected by such Lender or the LC Issuer, as the
case may be, and may change its Lending Installation from time to time. All
terms of this Agreement shall apply to any such Lending Installation and the
Loans, Facility LCs, participations in LC Obligations and any Notes issued
hereunder shall be deemed held by each Lender or the LC Issuer, as the case may
be, for the benefit of any such Lending Installation. Each Lender and the LC
Issuer may, by written notice to the Administrative Agent and the Borrower in
accordance with Article XIII, designate replacement or additional Lending
Installations through which Loans will be made by it or Facility LCs will be
issued by it and for whose account Loan payments or payments with respect to
Facility LCs are to be made.

         2.19.    Non-Receipt of Funds by the Administrative Agent. Unless the
Borrower or a Lender, as the case may be, notifies the Administrative Agent
prior to the date on which it is scheduled to make payment to the Administrative
Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case
of the Borrower, a payment of principal, interest or fees to the Administrative
Agent for the account of the Lenders, that it does not intend to make such
payment, the Administrative Agent may assume that such payment has been made.
The Administrative Agent may, but shall not be obligated to, make the amount of
such payment available to the intended recipient in reliance upon such
assumption. If such Lender or the Borrower, as the case may be, has not in fact
made such payment to the Administrative Agent, the recipient of such payment
shall, on demand by the Administrative Agent, repay to the Administrative Agent
the amount so made available together with interest thereon in respect of each
day during the period commencing on the date such amount was so made available
by the Administrative Agent until the date the Administrative Agent recovers
such amount at a rate per annum equal to (x) in the case of payment by a Lender,
the Federal Funds Effective Rate for such day for the first three days and,
thereafter, the interest rate applicable to the relevant Loan or (y) in the case
of payment by the Borrower, the interest rate applicable to the relevant Loan.

2.20.    Facility LCs.

         2.20.1.  Issuance. Subject to the terms and conditions of this
Agreement, the LC Issuer agrees to keep outstanding on and after the date hereof
the standby letters of credit for the account of the Borrower which were issued
by the LC Issuer and which are further described on Schedule 4 (collectively,
the "Existing Facility LCs"). Each Existing Facility LC shall constitute a
Facility LC for all purposes of this Agreement. For purposes hereof, the
Existing Facility LCs are deemed to be issued on the date hereof. Furthermore,
the LC Issuer hereby agrees, on the terms and conditions set forth in this
Agreement, to issue standby and commercial letters of credit (each, a "Facility
LC") and to renew, extend, increase, decrease or otherwise modify each Facility
LC ("Modify," and each such action a "Modification"), from time to time from and
including the date of this Agreement and prior to the Facility Termination Date
upon the request of the Borrower; provided that immediately after each such
Facility LC is issued or Modified, (i) the aggregate amount of the outstanding
LC Obligations shall not exceed $50,000,000 and (ii) the Aggregate Outstanding
Credit Exposure shall not exceed the Aggregate Commitment. No Facility LC shall
have an expiry date later than the earlier of (a) the fifth Business Day prior
to the Facility Termination Date and (b) one year after its issuance (or, if
such Facility LC shall have been renewed, one year after its renewal).

         2.20.2.  Participations. Upon the issuance or Modification by the LC
Issuer of a Facility LC in accordance with this Section 2.20, the LC Issuer
shall be deemed, without further action by any party hereto, to have
unconditionally and irrevocably sold to each Lender, and each Lender shall be
deemed, without further action by any party hereto, to have unconditionally and
irrevocably purchased from the LC Issuer, a participation in such Facility LC
(and each Modification thereof) and the related LC Obligations in proportion to
its Pro Rata Share.

         2.20.3.  Notice. Subject to Section 2.20.1, the Borrower shall give the
LC Issuer notice prior to 10:00 a.m. (Dallas time) at least five Business Days
prior to the proposed date of issuance or Modification of each Facility LC,
specifying the beneficiary, the proposed date of issuance (or Modification) and
the expiry date of such Facility LC, and describing the proposed terms of such
Facility LC and the nature of the transactions proposed to be supported thereby.
Upon receipt of such notice, the LC Issuer shall promptly notify the
Administrative Agent, and the Administrative Agent shall promptly notify each
Lender, of the contents thereof and of the amount of such Lender's participation
in such proposed Facility LC. The issuance or Modification by the LC Issuer of
any Facility LC shall, in addition to the conditions precedent set forth in
Article IV (the satisfaction of which the LC Issuer shall have no duty to
ascertain), be subject to the conditions precedent that such Facility LC shall
be reasonably satisfactory to the LC Issuer and that the Borrower shall have
executed and delivered such application agreement and/or such other instruments
and agreements relating to such Facility LC as the LC Issuer shall have
reasonably requested (each, a "Facility LC Application"). In the event of any
conflict between the terms of this Agreement and the terms of any Facility LC
Application, the terms of this Agreement shall control.

                                       22

         2.20.4.  LC Fees. The Borrower shall pay to the Administrative Agent,
for the account of the Lenders ratably in accordance with their respective Pro
Rata Shares, (i) with respect to each standby Facility LC, a letter of credit
fee at a per annum rate equal to the Applicable Margin for Eurodollar Loans in
effect from time to time on the average daily undrawn stated amount under such
standby Facility LC, such fee to be payable in arrears on each Payment Date, and
(ii) with respect to each commercial Facility LC, a one-time letter of credit
fee in an amount equal to 0.125% of the initial stated amount (or, with respect
to a Modification of any such commercial Facility LC which increases the stated
amount thereof, such increase in the stated amount) thereof, such fee to be
payable on the date of such issuance or increase (each such fee described in
this sentence an "LC Fee"). The Borrower shall also pay to the LC Issuer for its
own account (x) at the time of issuance of each Facility LC, a fronting fee in
an amount equal to 0.125% of the initial stated amount (or with respect to a
Modification of any such standby Facility LC which increases the stated amount
thereof, such increase in the stated amount), and (y) documentary and processing
charges in connection with the issuance or Modification of and draws under
Facility LCs in accordance with the LC Issuer's standard schedule for such
charges as in effect from time to time.

         2.20.5.  Administration; Reimbursement by Lenders. Upon receipt from
the beneficiary of any Facility LC of any demand for payment under such Facility
LC, the LC Issuer shall notify the Administrative Agent and the Administrative
Agent shall promptly notify the Borrower and each other Lender as to the amount
to be paid by the LC Issuer as a result of such demand and the proposed payment
date (the "LC Payment Date"). The responsibility of the LC Issuer to the
Borrower and each Lender shall be only to determine that the documents
(including each demand for payment) delivered under each Facility LC in
connection with such presentment shall be in conformity in all material respects
with such Facility LC. The LC Issuer shall endeavor to exercise the same care in
the issuance and administration of the Facility LCs as it does with respect to
letters of credit in which no participations are granted, it being understood
that in the absence of any gross negligence or willful misconduct by the LC
Issuer, each Lender shall be unconditionally and irrevocably liable without
regard to the occurrence of any Default or any condition precedent whatsoever,
to reimburse the LC Issuer on demand for (i) such Lender's Pro Rata Share of the
amount of each payment made by the LC Issuer under each Facility LC to the
extent such amount is not reimbursed by the Borrower pursuant to Section 2.20.6
below, plus (ii) interest on the foregoing amount to be reimbursed by such
Lender, for each day from the date of the LC Issuer's demand for such
reimbursement (or, if such demand is made after 11:00 a.m. (Dallas time) on such
date, from the next succeeding Business Day) to the date on which such Lender
pays the amount to be reimbursed by it, at a rate of interest per annum equal to
the Federal Funds Effective Rate for the first three days and, thereafter, at a
rate of interest equal to the rate applicable to Floating Rate Advances.

         2.20.6.  Reimbursement by Borrower. The Borrower shall be irrevocably
and unconditionally obligated to reimburse the LC Issuer on or before the
applicable LC Payment Date for any amounts to be paid by the LC Issuer upon any
drawing under any Facility LC, without presentment, demand, protest or other
formalities of any kind; provided that neither the Borrower nor any Lender shall
hereby be precluded from

                                       23

<PAGE>

asserting any claim for direct (but not consequential) damages suffered by the
Borrower or such Lender to the extent, but only to the extent, caused by (i) the
willful misconduct or gross negligence of the LC Issuer in determining whether a
request presented under any Facility LC issued by it complied with the terms of
such Facility LC or (ii) the LC Issuer's failure to pay under any Facility LC
issued by it after the presentation to it of a request strictly complying with
the terms and conditions of such Facility LC. All such amounts paid by the LC
Issuer and remaining unpaid by the Borrower shall bear interest, payable on
demand, for each day until paid at a rate per annum equal to (x) the rate
applicable to Floating Rate Advances for such day if such day falls on or before
the applicable LC Payment Date and (y) the sum of 2% plus the rate applicable to
Floating Rate Advances for such day if such day falls after such LC Payment
Date. The LC Issuer will pay to each Lender ratably in accordance with its Pro
Rata Share all amounts received by it from the Borrower for application in
payment, in whole or in part, of the Reimbursement Obligation in respect of any
Facility LC issued by the LC Issuer, but only to the extent such Lender has made
payment to the LC Issuer in respect of such Facility LC pursuant to Section
2.20.5. Subject to the terms and conditions of this Agreement (including without
limitation the submission of a Borrowing Notice in compliance with Section 2.9
and the satisfaction of the applicable conditions precedent set forth in Article
IV), the Borrower may request an Advance hereunder for the purpose of satisfying
any Reimbursement Obligation.

         2.20.7.  Obligations Absolute. The Borrower's obligations under this
Section 2.20 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment which the
Borrower may have or have had against the LC Issuer, any Lender or any
beneficiary of a Facility LC. The Borrower further agrees with the LC Issuer and
the Lenders that the LC Issuer and the Lenders shall not be responsible for, and
the Borrower's Reimbursement Obligation in respect of any Facility LC shall not
be affected by, among other things, the validity or genuineness of documents or
of any endorsements thereon, even if such documents should in fact prove to be
in any or all respects invalid, fraudulent or forged, or any dispute between or
among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or
any financing institution or other party to whom any Facility LC may be
transferred or any claims or defenses whatsoever of the Borrower or of any of
its Affiliates against the beneficiary of any Facility LC or any such
transferee. The LC Issuer shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Facility LC. The Borrower
agrees that any action taken or omitted by the LC Issuer or any Lender under or
in connection with each Facility LC and the related drafts and documents, if
done without gross negligence, bad faith or willful misconduct, shall be binding
upon the Borrower and shall not put the LC Issuer or any Lender under any
liability to the Borrower. Nothing in this Section 2.20.7 is intended to limit
the right of the Borrower to make a claim against the LC Issuer for damages as
contemplated by the proviso to the first sentence of Section 2.20.6.

         2.20.8.  Actions of LC Issuer. The LC Issuer shall be entitled to rely,
and shall be fully protected in relying, upon any Facility LC, draft, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype

                                       24

<PAGE>

         message, statement, order or other document reasonably believed by it
         to be genuine and correct and to have been signed, sent or made by the
         proper Person or Persons, and upon advice and statements of legal
         counsel, independent accountants and other experts selected by the LC
         Issuer. The LC Issuer shall be fully justified in failing or refusing
         to take any action under this Agreement unless it shall first have
         received such advice or concurrence of the Required Lenders as it
         reasonably deems appropriate or it shall first be indemnified to its
         reasonable satisfaction by the Lenders against any and all liability
         and expense which may be incurred by it by reason of taking or
         continuing to take any such action. Notwithstanding any other provision
         of this Section 2.20, the LC Issuer shall in all cases be fully
         protected in acting, or in refraining from acting, under this Agreement
         in accordance with a request of the Required Lenders, and such request
         and any action taken or failure to act pursuant thereto shall be
         binding upon the Lenders and any future holders of a participation in
         any Facility LC.

                  2.20.9.  Indemnification. The Borrower hereby agrees to
         indemnify and hold harmless each Lender, the LC Issuer and the
         Administrative Agent, and their respective directors, officers, agents
         and employees from and against any and all claims and damages, losses,
         liabilities, costs or expenses (including reasonable attorneys' fees
         and disbursements) which such Lender, the LC Issuer or the
         Administrative Agent may incur (or which may be claimed against such
         Lender, the LC Issuer or the Administrative Agent by any Person
         whatsoever) by reason of or in connection with the issuance, execution
         and delivery or transfer of or payment or failure to pay under any
         Facility LC or any actual or proposed use of any Facility LC,
         including, without limitation, any claims, damages, losses,
         liabilities, costs or expenses which the LC Issuer may incur by reason
         of or in connection with (i) the failure of any other Lender to fulfill
         or comply with its obligations to the LC Issuer hereunder (but nothing
         herein contained shall affect any rights the Borrower may have against
         any defaulting Lender) or (ii) by reason of or on account of the LC
         Issuer issuing any Facility LC which specifies that the term
         "Beneficiary" included therein includes any successor by operation of
         law of the named Beneficiary, but which Facility LC does not require
         that any drawing by any such successor Beneficiary be accompanied by a
         copy of a legal document, satisfactory to the LC Issuer, evidencing the
         appointment of such successor Beneficiary; provided that the Borrower
         shall not be required to indemnify any Lender, the LC Issuer or the
         Administrative Agent or any director, officer, agent or employee
         thereof for any claims, damages, losses, liabilities, costs or expenses
         to the extent, but only to the extent, caused by (x) the willful
         misconduct, bad faith or gross negligence of the LC Issuer in
         determining whether a request presented under any Facility LC complied
         with the terms of such Facility LC or (y) the LC Issuer's failure to
         pay under any Facility LC after the presentation to it of a request
         strictly complying with the terms and conditions of such Facility LC.
         Nothing in this Section 2.20.9 is intended to limit the obligations of
         the Borrower under any other provision of this Agreement.

                  2.20.10. Lenders' Indemnification. Each Lender shall, ratably
         in accordance with its Pro Rata Share, indemnify the LC Issuer, its
         Affiliates and their respective directors, officers, agents and
         employees (to the extent not reimbursed by the Borrower) against any
         cost, expense (including reasonable counsel fees and disbursements),
         claim, demand, action, loss or liability (except such as result from
         such

                                       25

<PAGE>

         indemnitees' gross negligence or willful misconduct or the LC Issuer's
         failure to pay under any Facility LC after the presentation to it of a
         request strictly complying with the terms and conditions of the
         Facility LC) that such indemnitees may suffer or incur in connection
         with this Section 2.20 or any action taken or omitted by such
         indemnitees hereunder.

                  2.20.11. Facility LC Collateral Account. The Borrower agrees
         that it will, after the occurrence of a Default and upon the request of
         the Administrative Agent or the Required Lenders and until the final
         expiration date of any Facility LC and thereafter as long as any amount
         is payable to the LC Issuer or the Lenders in respect of any Facility
         LC, maintain a special collateral account pursuant to arrangements
         satisfactory to the Administrative Agent (the "Facility LC Collateral
         Account") at the Administrative Agent's office at the address specified
         pursuant to Article XIII, in the name of the Borrower but under the
         sole dominion and control of the Administrative Agent, for the benefit
         of the Lenders and in which the Borrower shall have no interest other
         than as set forth in Section 8.1. The Borrower hereby pledges, assigns
         and grants to the Administrative Agent, on behalf of and for the
         ratable benefit of the Lenders and the LC Issuer, a security interest
         in all of the Borrower's right, title and interest in and to all funds
         which may from time to time be on deposit in the Facility LC Collateral
         Account to secure the prompt and complete payment and performance of
         the Obligations. The Administrative Agent will invest any funds on
         deposit from time to time in the Facility LC Collateral Account in
         certificates of deposit of Bank One having a maturity not exceeding 30
         days. Nothing in this Section 2.20.11 shall either obligate the
         Administrative Agent to require the Borrower to deposit any funds in
         the Facility LC Collateral Account or limit the right of the
         Administrative Agent to release any funds held in the Facility LC
         Collateral Account in each case other than as required by Section 8.1.

                  2.20.12. Rights as a Lender. In its capacity as a Lender, the
         LC Issuer shall have the same rights and obligations as any other
         Lender.

         2.21.    Replacement of Lender. If the Borrower is required pursuant to
Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any
Lender's obligation to make or continue, or to convert Floating Rate Advances
into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender
so affected an "Affected Lender"), the Borrower may elect, if such amounts
continue to be charged or such suspension is still effective, to replace such
Affected Lender as a Lender party to this Agreement, provided that no Default or
Unmatured Default shall have occurred and be continuing at the time of such
replacement, and provided further that, concurrently with such replacement, (i)
another bank or other entity which is reasonably satisfactory to the Borrower
and the Administrative Agent shall agree, as of such date, to purchase for cash
the Credit Extensions and other Obligations due to the Affected Lender pursuant
to an assignment substantially in the form of Exhibit C and to become a Lender
for all purposes under this Agreement and to assume all obligations of the
Affected Lender to be terminated as of such date and to comply with the
requirements of Section 12.3 applicable to assignments, and (ii) the Borrower
shall pay to such Affected Lender in same day funds on the day of such
replacement (A) all interest, fees and other amounts then accrued but unpaid to
such Affected Lender by the Borrower hereunder to and including the date of
termination, including

                                       26

<PAGE>

without limitation payments due to such Affected Lender under Sections 3.1, 3.2
and 3.5, and (B) an amount, if any, equal to the payment which would have been
due to such Lender on the day of such replacement under Section 3.4 had the
Credit Extensions of such Affected Lender been prepaid on such date rather than
sold to the replacement Lender.

         2.22.    Swing Line Subfacility.

                  2.22.1.  Conditions. For the convenience of the parties, the
         Administrative Agent, solely for its own account, may make any
         requested Advance under the Revolving Credit Facility (which request
         must be made before 1:00 p.m. (Dallas time) on the Business Day the
         Advance is to be made and may be telephonic if confirmed in writing
         within two Business Days) in the minimum amount of $100,000 (or a
         greater integral multiple of $100,000) directly to the Borrower as a
         Swing Line Advance without requiring each other Lender to fund its Pro
         Rata Share thereof on such Business Day. Swing Line Advances are
         subject to the following conditions:

                  (i)      Each Swing Line Advance must occur on a Business Day
         before the Facility Termination Date;

                  (ii)     The aggregate principal outstanding of all Swing Line
         Advances may not exceed $15,000,000; the aggregate principal
         outstanding of all Swing Line Advances, all other Advances under the
         Revolving Credit Facility, and all LC Obligations may not exceed the
         Aggregate Commitment under the Revolving Credit Facility; and no Swing
         Line Advance shall be made which would cause the aggregate principal
         outstanding of all Loans (including Swing Line Advances) made by the
         Administrative Agent under the Revolving Credit Facility to exceed the
         Administrative Agent's Commitment under the Revolving Credit Facility;

                  (iii)    Each Swing Line Advance, along with accrued but
         unpaid interest on such Swing Line Advance, shall be paid in full by
         the Borrower on the Business Day immediately succeeding the date of
         such Swing Line Advance by the funding of an Advance under the
         Revolving Credit Facility and in any event on the Facility Termination
         Date; and

                  (iv)     Each Swing Line Advance shall be a Floating Rate
         Advance.

                  2.22.2.  Lenders' Funding of Swing Line Advances as Advances
         Under Revolving Credit Facility. The Administrative Agent shall give to
         the Lenders notice of each Swing Line Advance not later than 3:00 p.m.
         (Dallas time) on the date of such Swing Line Advance, which notice
         shall, on behalf of the Borrower (and for such purpose the Borrower
         hereby irrevocably directs the Administrative Agent to act on its
         behalf), request each Lender to make, and each Lender hereby agrees to
         make, an Advance in an amount equal to such Lender's Pro Rata Share of
         the aggregate amount of the Swing Line Advances (the "Refunded Swing
         Line Advances") outstanding on the date of such notice, to repay the
         Administrative Agent. Each Lender shall make the amount of such Advance
         available to the Administrative Agent in immediately available funds,
         not later than noon (Dallas time) one Business Day after the date of
         such notice. The proceeds of such

                                       27

<PAGE>

         Advance shall be immediately made available to the Administrative Agent
         for application by the Administrative Agent to the repayment of the
         Refunded Swing Line Advances. The Borrower irrevocably authorizes the
         Administrative Agent to charge the Borrower's accounts with the
         Administrative Agent in order to immediately pay the amount of such
         Refunded Swing Line Advances to the extent amounts received from the
         Lenders are not sufficient to repay in full such Refunded Swing Line
         Advances (with notice of such charge being provided to the Borrower,
         provided that the failure to give such notice shall not affect the
         validity of such charge). All such Refunded Swing Line Advances shall
         be subject to all provisions of this Agreement concerning Advances
         under the Revolving Credit Facility. If prior to the time an Advance
         would otherwise have been made pursuant to this section, Advances may
         not be made as contemplated by this section, each Lender shall
         irrevocably and unconditionally purchase and receive from the
         Administrative Agent a ratable participation in such Swing Line Advance
         and shall make available to the Administrative Agent in immediately
         available funds its Pro Rata Share of such unpaid amount, together with
         interest from the date when its payment was due to, but not including,
         the date of payment. If a Lender does not promptly pay its amount upon
         the Administrative Agent's demand, and until such Lender makes the
         required payment, the Administrative Agent is deemed to continue to
         have outstanding a Swing Line Advance in the amount of such Lender's
         unpaid obligation. The Borrower shall make each payment of all or any
         part of any Swing Line Advance to the Administrative Agent for the
         ratable benefit of the Administrative Agent and those Lenders who have
         funded their participations in Swing Line Advances under this Section
         (but all interest accruing on Swing Line Advances before the funding
         date of any Advance under the Revolving Credit Facility to repay such
         Swing Line Advance or any participation is payable solely to the
         Administrative Agent for its own account).

         2.23.    Limitation of Interest. The Borrower, the Administrative Agent
and the Lenders intend to strictly comply with all applicable laws, including
applicable usury laws. Accordingly, the provisions of this Section 2.23 shall
govern and control over every other provision of this Agreement or any other
Loan Document which conflicts or is inconsistent with this Section 2.23, even if
such provision declares that it controls. As used in this Section 2.23, the term
"interest" includes the aggregate of all charges, fees, benefits or other
compensation which constitute interest under applicable law, provided that, to
the maximum extent permitted by applicable law, (a) any non-principal payment
shall be characterized as an expense or as compensation for something other than
the use, forbearance or detention of money and not as interest, and (b) all
interest at any time contracted for, reserved, charged or received shall be
amortized, prorated, allocated and spread, in equal parts during the full term
of the Obligations. In no event shall the Borrower or any other Person be
obligated to pay, or any Lender have any right or privilege to reserve, receive
or retain, (a) any interest in excess of the maximum amount of nonusurious
interest permitted under the laws of the State of Texas or the applicable laws
(if any) of the United States or of any other applicable state, or (b) total
interest in excess of the amount which such Lender could lawfully have
contracted for, reserved, received, retained or charged had the interest been
calculated for the full term of the Obligations at the Maximum Rate. On each
day, if any, that the interest rate (the "Stated Rate") called for under this
Agreement or any other Loan Document exceeds the Maximum Rate, the rate at which
interest shall accrue shall automatically be fixed by operation of this sentence
at the Maximum Rate for that day, and shall remain fixed at the Maximum Rate for
each day thereafter until the total amount of interest accrued equals the

                                       28

<PAGE>

total amount of interest which would have accrued if there were no such ceiling
rate as is imposed by this sentence. Thereafter, interest shall accrue at the
Stated Rate unless and until the Stated Rate again exceeds the Maximum Rate when
the provisions of the immediately preceding sentence shall again automatically
operate to limit the interest accrual rate. The daily interest rates to be used
in calculating interest at the Maximum Rate shall be determined by dividing the
applicable Maximum Rate per annum by the number of days in the calendar year for
which such calculation is being made. None of the terms and provisions contained
in this Agreement or in any other Loan Document which directly or indirectly
relate to interest shall ever be construed without reference to this Section
2.23, or be construed to create a contract to pay for the use, forbearance or
detention of money at an interest rate in excess of the Maximum Rate. If the
term of any Obligation is shortened by reason of acceleration of maturity as a
result of any Default or by any other cause, or by reason of any required or
permitted prepayment, and if for that (or any other) reason any Lender at any
time, including but not limited to, the stated maturity, is owed or receives
(and/or has received) interest in excess of interest calculated at the Maximum
Rate, then and in any such event all of any such excess interest shall be
canceled automatically as of the date of such acceleration, prepayment or other
event which produces the excess, and, if such excess interest has been paid to
such Lender, it shall be credited pro tanto against the then-outstanding
principal balance of the Borrower's obligations to such Lender, effective as of
the date or dates when the event occurs which causes it to be excess interest,
until such excess is exhausted or all of such principal has been fully paid and
satisfied, whichever occurs first, and any remaining balance of such excess
shall be promptly refunded to its payor. Chapter 346 of the Texas Finance Code
(which regulates certain revolving credit accounts (formerly Tex. Rev. Civ.
Stat. Ann. Art. 5069, Ch. 15)) shall not apply to this Agreement or to any Loan,
nor shall this Agreement or any Loan be governed by or be subject to the
provisions of such Chapter 346 in any manner whatsoever.

                                  ARTICLE III

                             YIELD PROTECTION; TAXES

         3.1.     Yield Protection. If, on or after the date of this Agreement,
the adoption of any law or any governmental or quasi-governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law), or any change in the interpretation or administration thereof by any
governmental or quasi-governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by any
Lender or applicable Lending Installation or the LC Issuer with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency:

                  (i)      subjects any Lender or any applicable Lending
         Installation or the LC Issuer to any Taxes, or changes the basis of
         taxation of payments (other than with respect to Excluded Taxes) to any
         Lender or the LC Issuer in respect of its Eurodollar Loans, Facility
         LCs or participations therein, or

                  (ii)     imposes or increases or deems applicable any reserve,
         assessment, insurance charge, special deposit or similar requirement
         against assets of, deposits with or for the account of, or credit
         extended by, any Lender or any applicable Lending

                                       29

<PAGE>

         Installation or the LC Issuer (other than reserves and assessments
         taken into account in determining the interest rate applicable to
         Eurodollar Advances), or

                  (iii)    imposes any other condition the result of which is to
         increase the cost to any Lender or any applicable Lending Installation
         or the LC Issuer of making, funding or maintaining its Eurodollar
         Loans, or of issuing or participating in Facility LCs, or reduces any
         amount receivable by any Lender or any applicable Lending Installation
         or the LC Issuer in connection with its Eurodollar Loans, Facility LCs
         or participations therein, or requires any Lender or any applicable
         Lending Installation or the LC Issuer to make any payment calculated by
         reference to the amount of Eurodollar Loans, Facility LCs or
         participations therein held or interest or LC Fees received by it, by
         an amount deemed material by such Lender or the LC Issuer as the case
         may be,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation or the LC Issuer, as the case may be, of making
or maintaining its Eurodollar Loans or Commitment or of issuing or participating
in Facility LCs or to reduce the return received by such Lender or applicable
Lending Installation or the LC Issuer, as the case may be, in connection with
such Eurodollar Loans, Commitment, Facility LCs or participations therein, then,
within 15 days of demand by such Lender or the LC Issuer, as the case may be,
the Borrower shall pay such Lender or the LC Issuer, as the case may be, such
additional amount or amounts as will compensate such Lender or the LC Issuer, as
the case may be, for such increased cost or reduction in amount received.

         3.2.     Changes in Capital Adequacy Regulations. If a Lender or the LC
Issuer determines the amount of capital required or expected to be maintained by
such Lender or the LC Issuer, any Lending Installation of such Lender or the LC
Issuer, or any corporation controlling such Lender or the LC Issuer is increased
as a result of a Change, then, within 15 days of demand by such Lender or the LC
Issuer, the Borrower shall pay such Lender or the LC Issuer the amount necessary
to compensate for any shortfall in the rate of return on the portion of such
increased capital which such Lender or the LC Issuer determines is attributable
to this Agreement, its Outstanding Credit Exposure or its Commitment to make
Loans and issue or participate in Facility LCs, as the case may be, hereunder
(after taking into account such Lender's or the LC Issuer's policies as to
capital adequacy). "Change" means (i) any change after the date of this
Agreement in the Risk-Based Capital Guidelines, or (ii) any adoption of or
change in any other law, governmental or quasi-governmental rule, regulation,
policy, guideline, interpretation, or directive (whether or not having the force
of law) after the date of this Agreement which affects the amount of capital
required or expected to be maintained by any Lender or the LC Issuer or any
Lending Installation or any corporation controlling any Lender or the LC Issuer.
"Risk-Based Capital Guidelines" means (i) the risk-based capital guidelines in
effect in the United States on the date of this Agreement, including transition
rules, and (ii) the corresponding capital regulations promulgated by regulatory
authorities outside the United States implementing the July 1988 report of the
Basle Committee on Banking Regulation and Supervisory Practices Entitled
"International Convergence of Capital Measurements and Capital Standards,"
including transition rules, and any amendments to such regulations adopted prior
to the date of this Agreement.

         3.3.     Availability of Types of Advances. If any Lender determines
that maintenance of its Eurodollar Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders determine that (i) deposits
of a type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to Eurodollar Advances does not
accurately reflect the cost of making or maintaining Eurodollar Advances, then
the Administrative Agent shall suspend the availability of Eurodollar Advances
and require any affected Eurodollar Advances to be repaid or converted to
Floating Rate Advances, subject to the payment of any funding indemnification
amounts required by Section 3.4.

         3.4.     Funding Indemnification. If any payment of a Eurodollar
Advance occurs on a date which is not the last day of the applicable Interest
Period, whether because of acceleration, prepayment or otherwise, or a
Eurodollar Advance is not made on the date specified by the Borrower for any
reason other than default by the Lenders, the Borrower will indemnify each
Lender for any loss or cost incurred by it resulting therefrom, including,
without limitation, any loss or cost in liquidating or employing deposits
acquired to fund or maintain such Eurodollar Advance.

         3.5.     Taxes.

                  (i)      All payments by the Borrower to or for the account of
         any Lender, the LC Issuer or the Administrative Agent hereunder or
         under any Note or Facility LC Application shall be made free and clear
         of and without deduction for any and all Taxes. If the Borrower shall
         be required by law to deduct any Taxes from or in respect of any sum
         payable hereunder to any Lender, the LC Issuer or the Administrative
         Agent, (a) the sum payable shall be increased as necessary so that
         after making all required deductions (including deductions applicable
         to additional sums payable under this Section 3.5) such Lender, the LC
         Issuer 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, (b) the Borrower shall make such deductions, (c) the
         Borrower shall pay the full amount deducted to the relevant authority
         in accordance with applicable law and (d) the Borrower shall furnish to
         the Administrative Agent the original copy of a receipt evidencing
         payment thereof within 30 days after such payment is made.

                  (ii)     In addition, the Borrower hereby agrees to pay any
         present or future stamp or documentary taxes and any other excise or
         property taxes, charges or similar levies which arise from any payment
         made hereunder or under any Note or Facility LC Application or from the
         execution or delivery of, or otherwise with respect to, this Agreement
         or any Note or Facility LC Application ("Other Taxes").

                  (iii)    The Borrower hereby agrees to indemnify the
         Administrative Agent, the LC Issuer and each Lender for the full amount
         of Taxes or Other Taxes (including, without limitation, any Taxes or
         Other Taxes imposed on amounts payable under this Section 3.5) paid by
         the Administrative Agent, the LC Issuer or such Lender and any
         liability (including penalties, interest and expenses) arising
         therefrom or with respect thereto. Payments due under this
         indemnification shall be made within 30 days of the

                                       31

<PAGE>

         date the Administrative Agent, the LC Issuer or such Lender makes
         demand therefor pursuant to Section 3.6.

                  (iv)     Each Lender that is not incorporated under the laws
         of the United States of America or a state thereof (each a "Non-U.S.
         Lender") agrees that it will, not more than ten Business Days after the
         date of this Agreement, (i) deliver to the Borrower and the
         Administrative Agent two duly completed copies of United States
         Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either
         case that such Lender is entitled to receive payments under this
         Agreement without deduction or withholding of any United States federal
         income taxes, and (ii) deliver to the Borrower and the Administrative
         Agent a United States Internal Revenue Form W-8 or W-9, as the case may
         be, and certify that it is entitled to an exemption from United States
         backup withholding tax. Each Non-U.S. Lender further undertakes to
         deliver to the Borrower and the Administrative Agent (x) renewals or
         additional copies of such form (or any successor form) on or before the
         date that such form expires or becomes obsolete, and (y) after the
         occurrence of any event requiring a change in the most recent forms so
         delivered by it, such additional forms or amendments thereto as may be
         reasonably requested by the Borrower or the Administrative Agent. All
         forms or amendments described in the preceding sentence shall certify
         that such Lender is entitled to receive payments under this Agreement
         without deduction or withholding of any United States federal income
         taxes, unless an event (including without limitation any change in
         treaty, law or regulation) has occurred prior to the date on which any
         such delivery would otherwise be required which renders all such forms
         inapplicable or which would prevent such Lender from duly completing
         and delivering any such form or amendment with respect to it and such
         Lender advises the Borrower and the Administrative Agent that it is not
         capable of receiving payments without any deduction or withholding of
         United States federal income tax.

                  (v)      For any period during which a Non-U.S. Lender has
         failed to provide the Borrower with an appropriate form pursuant to
         clause (iv), above (unless such failure is due to a change in treaty,
         law or regulation, or any change in the interpretation or
         administration thereof by any governmental authority, occurring
         subsequent to the date on which a form originally was required to be
         provided), such Non-U.S. Lender shall not be entitled to
         indemnification under this Section 3.5 with respect to Taxes imposed by
         the United States; provided that, should a Non-U.S. Lender which is
         otherwise exempt from or subject to a reduced rate of withholding tax
         become subject to Taxes because of its failure to deliver a form
         required under clause (iv) above, the Borrower shall take such steps as
         such Non-U.S. Lender shall reasonably request to assist such Non-U.S.
         Lender to recover such Taxes.

                  (vi)     Any Lender that is entitled to an exemption from or
         reduction of withholding tax with respect to payments under this
         Agreement or any Note pursuant to the law of any relevant jurisdiction
         or any treaty shall deliver to the Borrower (with a copy to the
         Administrative Agent), at the time or times prescribed by applicable
         law, such properly completed and executed documentation prescribed by
         applicable law as will permit such payments to be made without
         withholding or at a reduced rate.

                                       32

<PAGE>

                  (vii)    If the U.S. Internal Revenue Service or any other
         governmental authority of the United States or any other country or any
         political subdivision thereof asserts a claim that the Administrative
         Agent did not properly withhold tax from amounts paid to or for the
         account of any Lender (because the appropriate form was not delivered
         or properly completed, because such Lender failed to notify the
         Administrative Agent of a change in circumstances which rendered its
         exemption from withholding ineffective, or for any other reason), such
         Lender shall indemnify the Administrative Agent fully for all amounts
         paid, directly or indirectly, by the Administrative Agent as tax,
         withholding therefor, or otherwise, including penalties and interest,
         and including taxes imposed by any jurisdiction on amounts payable to
         the Administrative Agent under this subsection, together with all costs
         and expenses related thereto (including attorneys fees and time charges
         of attorneys for the Administrative Agent, which attorneys may be
         employees of the Administrative Agent). The obligations of the Lenders
         under this Section 3.5(vii) shall survive the payment of the
         Obligations and termination of this Agreement.

         3.6.     Lender Statements; Survival of Indemnity. To the extent
reasonably possible, each Lender shall designate an alternate Lending
Installation with respect to its Eurodollar Loans to reduce any liability of the
Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the
unavailability of Eurodollar Advances under Section 3.3, so long as such
designation is not, in the reasonable judgment of such Lender, disadvantageous
to such Lender. Each Lender shall deliver a written statement of such Lender to
the Borrower (with a copy to the Administrative Agent) as to the amount due, if
any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth
in reasonable detail the calculations upon which such Lender determined such
amount and shall be final, conclusive and binding on the Borrower in the absence
of manifest error. Determination of amounts payable under such Sections in
connection with a Eurodollar Loan shall be calculated as though each Lender
funded its Eurodollar Loan through the purchase of a deposit of the type and
maturity corresponding to the deposit used as a reference in determining the
Eurodollar Rate applicable to such Loan, whether in fact that is the case or
not. Unless otherwise provided herein, the amount specified in the written
statement of any Lender shall be payable within 15 days after receipt by the
Borrower of such written statement. The obligations of the Borrower under
Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and
termination of this Agreement.

                                   ARTICLE IV

                              CONDITIONS PRECEDENT

                                   ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Lenders that:

         5.1.     Existence and Standing. Each of the Borrower and its
Subsidiaries is a corporation, partnership (in the case of Subsidiaries only) or
limited liability company (in the

                                       35

<PAGE>

case of Subsidiaries only) duly and properly incorporated or organized, as the
case may be, validly existing and (to the extent such concept applies to such
entity) in good standing under the laws of its jurisdiction of incorporation or
organization, is duly qualified to transact business and is in good standing in
each jurisdiction in which its business is conducted except where the failure to
be so qualified could not reasonably be expected to have a Material Adverse
Effect.

         5.2.     Authorization and Validity. The Borrower has the corporate
power and authority and legal right to execute and deliver the Loan Documents to
which it is a party and to perform its obligations thereunder. The execution and
delivery by the Borrower of the Loan Documents to which it is a party and the
performance of its obligations thereunder have been duly authorized by proper
corporate proceedings, and the Loan Documents to which the Borrower is a party
constitute legal, valid and binding obligations of the Borrower enforceable
against the Borrower in accordance with their terms, except as enforceability
may be limited by bankruptcy, insolvency or similar laws affecting the
enforcement of creditors' rights generally or general principles of equity.

         5.3.     No Conflict; Government Consent. Neither the execution and
delivery by the Borrower of the Loan Documents to which it is a party, nor the
consummation of the transactions therein contemplated, nor compliance with the
provisions thereof will violate (i) any law, rule, regulation, order, writ,
judgment, injunction, decree or award binding on the Borrower or any of its
Subsidiaries other than violations which could not individually or in the
aggregate reasonably be expected to have a Material Adverse Effect or (ii) the
Borrower's or any Subsidiary's articles or certificate of incorporation,
partnership agreement, certificate of partnership, articles or certificate of
organization, by-laws, or operating or other management agreement, as the case
may be, or (iii) the provisions of any indenture, instrument or agreement to
which the Borrower or any of its Subsidiaries is a party or is subject, or by
which it, or its Property, is bound, or conflict with or constitute a default
thereunder, or result in, or require, the creation or imposition of any Lien in,
of or on the Property of the Borrower or a Subsidiary pursuant to the terms of
any such indenture, instrument or agreement. No order, consent, adjudication,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, or other action in respect of any
governmental or public body or authority, or any subdivision thereof, which has
not been obtained by the Borrower or any of its Subsidiaries, is required to be
obtained by the Borrower or any of its Subsidiaries in connection with the
execution and delivery of the Loan Documents, the borrowings under this
Agreement, the payment and performance by the Borrower of the Obligations or the
legality, validity, binding effect or enforceability of any of the Loan
Documents except for such orders, consents, adjudications, approvals, licenses,
authorizations or validations of, or filings, recordings or registrations with,
or exemptions by or other actions the failure to obtain or make could not
individually or in the aggregate reasonably be expected to have a Material
Adverse Effect.

         5.4.     Financial Statements. The December 31, 2002 consolidated
financial statements of the Borrower and its Subsidiaries heretofore delivered
to the Lenders were prepared in accordance with generally accepted accounting
principles in effect on the date such statements were prepared and fairly
present the consolidated financial condition and operations of the Borrower and
its Subsidiaries at such date and the consolidated results of their operations
for the period then ended.

                                       36

<PAGE>

         5.5.     Material Adverse Change. Since December 31, 2002 there has
been no change in the business, Property, financial condition or results of
operations of the Borrower and its Subsidiaries taken as a whole which could
reasonably be expected to have a Material Adverse Effect.

         5.6.     Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes due pursuant to said returns or pursuant to any
assessment received by the Borrower or any of its Subsidiaries, except such
taxes, if any, as are being contested in good faith and as to which adequate
reserves have been provided in accordance with Agreement Accounting Principles
and as to which no Lien exists and except where failure to file or pay could not
individually or in the aggregate reasonably be expected to have a Material
Adverse Effect. With respect to all United States federal tax returns, the
latest period for which the Borrower and its Subsidiaries have been examined or
for which the applicable statute of limitations has expired is the fiscal year
ended March 31, 1999. No tax Liens have been filed and no claims are being
asserted with respect to any such taxes which individually or in the aggregate
have a Material Adverse Effect. The charges, accruals and reserves on the books
of the Borrower and its Subsidiaries in respect of any taxes or other
governmental charges are adequate. If any of its Subsidiaries is a limited
liability company, each such limited liability company qualifies for partnership
tax treatment under United States federal tax law.

         5.7.     Litigation and Contingent Obligations. There is no litigation,
arbitration, governmental investigation, proceeding or inquiry pending or, to
the knowledge of any of their officers, threatened against or affecting the
Borrower or any of its Subsidiaries which could individually or in the aggregate
reasonably be expected to have a Material Adverse Effect or which seeks to
prevent, enjoin or delay the making of any Credit Extensions. Other than any
liabilities which could not individually or in the aggregate reasonably be
expected to have a Material Adverse Effect, the Borrower has no material
contingent obligations not provided for or disclosed in the financial statements
referred to in Section 5.4.

         5.8.     Subsidiaries. Schedule 2 contains an accurate list of all
Subsidiaries of the Borrower as of the date of this Agreement, setting forth
their respective jurisdictions of organization and the percentage of their
respective capital stock or other ownership interests owned by the Borrower or
other Subsidiaries. All of the issued and outstanding shares of capital stock or
other ownership interests of such Subsidiaries have been (to the extent such
concepts are relevant with respect to such ownership interests) duly authorized
and issued and are fully paid and non-assessable.

         5.9.     ERISA. Neither the Borrower nor any other member of the
Controlled Group has incurred in the aggregate Unfunded Liabilities of all
Single Employer Plans in an amount that could reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any other member of the
Controlled Group has incurred, or is reasonably expected to incur, any
withdrawal liability to Multiemployer Plans in the aggregate in an amount that
could reasonably be expected to have a Material Adverse Effect. Each Plan
complies in all material respects with all applicable requirements of law and
regulations, and no Reportable Event has occurred with respect to any Plan that
could reasonably be expected to have a Material Adverse Effect.

         5.10.    Accuracy of Information. No information, exhibit or report
furnished by the Borrower or any of its Subsidiaries to the Administrative Agent
or to any Lender in connection with the negotiation of, or compliance with, the
Loan Documents contained any misstatement of material fact or omitted to state a
material fact necessary to make the statements contained therein not misleading.

         5.11.    Regulation U. Margin stock (as defined in Regulation U)
constitutes less than 25% of the value of those assets of the Borrower and its
Subsidiaries which are subject to any limitation on sale, pledge, or other
restriction hereunder.

         5.12.    Material Agreements. The Borrower is not a party to any
agreement or instrument or subject to any charter or other corporate restriction
which could reasonably be expected to have a Material Adverse Effect. Neither
the Borrower nor any Subsidiary is in default in the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in (i)
any agreement to which it is a party, which default could reasonably be expected
to have a Material Adverse Effect or (ii) any agreement or instrument evidencing
or governing Indebtedness which aggregates in excess of $2,500,000.

         5.13.    Compliance With Laws. The Borrower and its Subsidiaries have
complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property except for any failure
to comply with any of the foregoing which could not reasonably be expected to
have a Material Adverse Effect.

         5.14.    Ownership of Properties. Except as set forth on Schedule 3, on
the date of this Agreement, the Borrower and its Subsidiaries will have good
title, free of all Liens other than those permitted by Section 6.12, to all of
the Property and assets reflected in the Borrower's most recent consolidated
financial statements provided to the Administrative Agent as owned by the
Borrower and its Subsidiaries.

         5.15.    Plan Assets; Prohibited Transactions. The Borrower is not an
entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA)
which is subject to Title I of ERISA or any plan (within the meaning of Section
4975 of the Code), and neither the execution of this Agreement nor the making of
Credit Extensions hereunder gives rise to a prohibited transaction within the
meaning of Section 406 of ERISA or Section 4975 of the Code.

         5.16.    Environmental Matters. In the ordinary course of its business,
the officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
concluded that Environmental Laws cannot reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any Subsidiary has received
any notice to the effect that its operations are not in material compliance with
any of the requirements of applicable Environmental Laws or are the subject of
any federal or state investigation evaluating whether any remedial action is
needed to respond to a release of any toxic or hazardous waste or

                                       38

<PAGE>

substance into the environment, which non-compliance or remedial action could
reasonably be expected to have a Material Adverse Effect.

         5.17.    Investment Company Act. Neither the Borrower nor any
Subsidiary is an "investment company" or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended.

         5.18.    Public Utility Holding Company Act. Neither the Borrower nor
any Subsidiary is a "holding company" or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

         5.19.    Subordinated Indebtedness. The Obligations constitute senior
indebtedness which is entitled to the benefits of the subordination provisions
of all outstanding Subordinated Indebtedness.

         5.20.    Post-Retirement Benefits. The present value of the expected
cost of post-retirement medical and insurance benefits payable by the Borrower
and its Subsidiaries to its employees and former employees, as estimated by the
Borrower in accordance with procedures and assumptions reasonably acceptable to
the Required Lenders, does not exceed $2,500,000.

         5.21.    Solvency.

                  (i)      Immediately after the consummation of the
         transactions to occur on the date hereof and immediately following the
         making of each Credit Extension, if any, made on the date hereof and
         after giving effect to the application of the proceeds of such Credit
         Extension, (a) the fair value of the assets of the Borrower and its
         Subsidiaries on a consolidated basis, at a fair valuation, will exceed
         the debts and liabilities, subordinated, contingent or otherwise, of
         the Borrower and its Subsidiaries on a consolidated basis; (b) the
         present fair saleable value of the Property of the Borrower and its
         Subsidiaries on a consolidated basis will be greater than the amount
         that will be required to pay the probable liability of the Borrower and
         its Subsidiaries on a consolidated basis on their debts and other
         liabilities, subordinated, contingent or otherwise, as such debts and
         other liabilities become absolute and matured; (c) the Borrower and its
         Subsidiaries on a consolidated basis will be able to pay their debts
         and liabilities, subordinated, contingent or otherwise, as such debts
         and liabilities become absolute and matured; and (d) the Borrower and
         its Subsidiaries on a consolidated basis will not have unreasonably
         small capital with which to conduct the businesses in which they are
         engaged as such businesses are now conducted and are proposed to be
         conducted after the date hereof.

                  (ii)     The Borrower does not intend to, or to permit any of
         its Subsidiaries to, and does not believe that it or any of its
         Subsidiaries will, incur debts beyond its ability to pay such debts as
         they mature, taking into account the timing of and amounts of cash to
         be received by it or any such Subsidiary and the timing of the amounts
         of cash to be payable on or in respect of its Indebtedness or the
         Indebtedness of any such Subsidiary.

         to any Person as a result of the release by the Borrower, any of its
         Subsidiaries, or any other Person of any toxic or hazardous waste or
         substance into the environment, and (b) any notice alleging any
         violation of any federal, state or local environmental, health or
         safety law or regulation by the Borrower or any of its Subsidiaries,

         Adverse Effect.

                  (viii)   Promptly upon the furnishing thereof to the
         shareholders of the Borrower, copies of all financial statements,

         time reasonably request.

         6.2.     Use of Proceeds. The Borrower will, and will cause each

keep its Property in good repair, working order and condition, and make all
necessary and proper repairs, renewals and replacements so that its business
carried on in connection therewith may be properly conducted at all times except
where such failure could not individually or in the aggregate reasonably be
expected to have a Material Adverse Effect.

         6.8.     Books and Records. The Borrower will, and will cause each
Subsidiary to, keep proper books of record and account in which full, true and
correct entries are made of all dealings and transactions in relation to its

material respects with all requirements of law.

         6.9.     Inspection. The Borrower will, and will cause each Subsidiary
to, permit the Administrative Agent and the Lenders, by their respective
representatives and agents, to inspect any of the Property, books and financial
records of the Borrower and each Subsidiary, to examine and make copies of the
books of accounts and other financial records of the Borrower and each
Subsidiary, and to discuss the affairs, finances and accounts of the Borrower
and each Subsidiary with, and to be advised as to the same by, their respective
officers at such reasonable times and intervals as the Administrative Agent or

Subsidiary is the survivor, and (b) the Borrower is in compliance with Section
6.23 and (iii) the Borrower may merge Subsidiaries with or into any other Person
in connection with dispositions of Property permitted pursuant to Section
6.11(ii).

         6.11.    Sale of Assets. The Borrower will not, nor will it permit any
Subsidiary to, lease, sell or otherwise dispose of its Property to any other
Person, except:

                  (i)      Sales of inventory in the ordinary course of
         business.

                  (ii)     Leases, sales or other dispositions of its Property
         that, together with all other Property of the Borrower and its
         Subsidiaries previously leased, sold or disposed of (other than

         Section during the twelve-month period ending with the month in which
         any such lease, sale or

         other encumbrances or charges against real property as are of a nature
         generally existing with respect to properties of a similar character

                                  ARTICLE VIII

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         8.1.     Acceleration; Facility LC Collateral Account.

                  (i)      If any Default described in Section 7.6 or 7.7
         occurs, the obligations of the Lenders to make Loans hereunder and the
         obligation and power of the LC Issuer to issue Facility LCs shall
         automatically terminate and the Obligations shall immediately become
         due and payable without any election or action on the part of the
         Administrative Agent, the LC Issuer or any Lender and the Borrower will
         be and become thereby unconditionally obligated, without any further
         notice, act or demand, to pay to the Administrative Agent an amount in
         immediately available funds, which funds shall be held in the Facility
         LC Collateral Account, equal to the difference of (x) the amount of LC
         Obligations at such time, less (y) the amount on deposit in the
         Facility LC Collateral Account at such time which is free and clear of
         all rights and claims of third parties and has not been applied against
         the Obligations (such difference, the "Collateral Shortfall Amount").
         If any other Default occurs, the Required Lenders (or the
         Administrative Agent with the consent of the Required Lenders) may (a)
         terminate or suspend the obligations of the Lenders to make Loans
         hereunder and the obligation and power of the LC Issuer to issue
         Facility LCs, or declare the Obligations to be due and payable, or
         both, whereupon the Obligations shall become immediately due and
         payable, without presentment, demand, protest or notice of any kind,
         all of which the Borrower hereby expressly waives, and (b) upon notice
         to the Borrower and in addition to the continuing right to demand
         payment of all amounts payable under this Agreement, make demand on the
         Borrower to pay, and the Borrower will, forthwith upon such demand and
         without any further notice or act, pay to the Administrative Agent the
         Collateral Shortfall Amount, which funds shall be deposited in the
         Facility LC Collateral Account.

                                       48

<PAGE>

                  (ii)     If at any time while any Default is continuing, the
         Administrative Agent determines that the Collateral Shortfall Amount at
         such time is greater than zero, the Administrative Agent may make
         demand on the Borrower to pay, and the Borrower will, forthwith upon
         such demand and without any further notice or act, pay to the
         Administrative Agent the Collateral Shortfall Amount, which funds shall
         be deposited in the Facility LC Collateral Account.

                  (iii)    The Administrative Agent may at any time or from time
         to time after funds are deposited in the Facility LC Collateral
         Account, apply such funds to the payment of the Obligations and any
         other amounts as shall from time to time have become due and payable by
         the Borrower to the Lenders or the LC Issuer under the Loan Documents.

                  (iv)     At any time while any Default is continuing, neither
         the Borrower nor any Person claiming on behalf of or through the
         Borrower shall have any right to withdraw any of the funds held in the
         Facility LC Collateral Account. After all of the Obligations have been
         indefeasibly paid in full and the Aggregate Commitment has been
         terminated, any funds remaining in the Facility LC Collateral Account
         shall be returned by the Administrative Agent to the Borrower or paid
         to whomever may be legally entitled thereto at such time.

                  (v)      If, within 30 days after acceleration of the maturity
         of the Obligations or termination of the obligations of the Lenders to
         make Loans and the obligation and power of the LC Issuer to issue
         Facility LCs hereunder as a result of any Default (other than any
         Default as described in Section 7.6 or 7.7) and before any judgment or
         decree for the payment of the Obligations due shall have been obtained
         or entered, the Required Lenders (in their sole discretion) shall so
         direct, the Administrative Agent shall, by notice to the Borrower,
         rescind and annul such acceleration and/or termination.

         8.2.     Amendments. Subject to the provisions of this Article VIII,
the Required Lenders (or the Administrative Agent with the consent in writing of
the Required Lenders) and the Borrower may enter into agreements supplemental
hereto for the purpose of adding or modifying any provisions to the Loan
Documents or changing in any manner the rights of the Lenders or the Borrower
hereunder or waiving any Default hereunder; provided, however, that no such
supplemental agreement shall, without the consent of the Super Majority Lenders
amend, modify, or delete the definition of Change of Control in Article I or
amend, modify, waive or delete Section 7.14, provided, further, however, that no
such supplemental agreement shall, without the consent of all of the Lenders:

                  (i)      Extend the final maturity of any Loan, or extend the
         expiry date of any Facility LC to a date after the Facility Termination
         Date or postpone any regularly scheduled payment of principal of any
         Loan or forgive all or any portion of the principal amount thereof or
         any Reimbursement Obligation related thereto, or reduce the rate or the
         unused fee due under Section 2.5 or extend the time of payment of
         interest or fees thereon or Reimbursement Obligations related thereto.

                  (ii)     Reduce the percentage specified in the definition of
         Required Lenders.

                                       49

<PAGE>

                  (iii)    Extend the Facility Termination Date, or reduce the
         amount or extend the payment date for, the mandatory payments required
         under Section 2.2, or increase the amount of the Aggregate Commitment
         (except such increase in the Aggregate Commitment pursuant to Section
         2.6, whereby only the consent of the Purchaser(s) and the Increasing
         Lender(s) shall be necessary), the Commitment of any Lender hereunder
         (except pursuant to Section 2.6) or the commitment to issue Facility
         LCs, or permit the Borrower to assign its rights under this Agreement.

                  (iv)     Amend this Section 8.2.

                  (v)      Release any Guarantor except where the sale of all or
         substantially all of the assets or equity interests in a Guarantor is
         otherwise permitted hereunder, in which event the Administrative Agent
         shall execute and deliver to Borrower such release upon such sale.

No amendment of any provision of this Agreement relating to the Administrative
Agent shall be effective without the written consent of the Administrative
Agent, and no amendment of any provision relating to the LC Issuer shall be
effective without the written consent of the LC Issuer. The Administrative Agent
may waive payment of the fee required under Section 12.3.2 without obtaining the
consent of any other party to this Agreement.

         8.3.     Preservation of Rights. No delay or omission of the Lenders,
the LC Issuer or the Administrative Agent to exercise any right under the Loan
Documents shall impair such right or be construed to be a waiver of any Default
or an acquiescence therein, and the making of a Credit Extension notwithstanding
the existence of a Default or the inability of the Borrower to satisfy the
conditions precedent to such Credit Extension shall not constitute any waiver or
acquiescence. Any single or partial exercise of any such right shall not
preclude other or further exercise thereof or the exercise of any other right,
and no waiver, amendment or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by the Lenders required pursuant to Section 8.2, and then only to the
extent in such writing specifically set forth. All remedies contained in the
Loan Documents or by law afforded shall be cumulative and all shall be available
to the Administrative Agent, the LC Issuer and the Lenders until the Obligations
have been paid in full.

                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1.     Survival of Representations. All representations and
warranties of the Borrower contained in this Agreement shall survive the making
of the Credit Extensions herein contemplated.

         9.2.     Governmental Regulation. Anything contained in this Agreement
to the contrary notwithstanding, neither the LC Issuer nor any Lender shall be
obligated to extend credit to the Borrower in violation of any limitation or
prohibition provided by any applicable statute or regulation.

                                       50

<PAGE>

         9.3.     Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

         9.4.     ENTIRE AGREEMENT. THE LOAN DOCUMENTS EMBODY THE ENTIRE
AGREEMENT AND UNDERSTANDING AMONG THE BORROWER, THE ADMINISTRATIVE AGENT, THE LC
ISSUER AND THE LENDERS AND SUPERSEDE ALL PRIOR AGREEMENTS AND UNDERSTANDINGS
AMONG THE BORROWER, THE ADMINISTRATIVE AGENT, THE LC ISSUER AND THE LENDERS
RELATING TO THE SUBJECT MATTER THEREOF OTHER THAN THE FEE LETTER DESCRIBED IN
SECTION 10.13. THE LOAN DOCUMENTS MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE
OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE
PARTIES HERETO. THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES HERETO.

         9.5.     Several Obligations; Benefits of this Agreement. The
respective obligations of the Lenders hereunder are several and not joint and no
Lender shall be the partner or agent of any other (except to the extent to which
the Administrative Agent is authorized to act as such). The failure of any
Lender to perform any of its obligations hereunder shall not relieve any other
Lender from any of its obligations hereunder. This Agreement shall not be
construed so as to confer any right or benefit upon any Person other than the
parties to this Agreement and their respective successors and assigns, provided,
however, that the parties hereto expressly agree that the Arranger shall enjoy
the benefits of the provisions of Sections 9.6, 9.10 and 10.11 to the extent
specifically set forth therein and shall have the right to enforce such
provisions on its own behalf and in its own name to the same extent as if it
were a party to this Agreement.

         9.6.     Expenses; Indemnification.

                  (i)      The Borrower shall reimburse the Administrative
         Agent, and the Arranger for any costs, internal charges for fees and
         time charges of attorneys who are employees of the Administrative Agent
         and the Arranger and all reasonable out-of-pocket expenses (including
         attorneys' fees) paid or incurred by the Administrative Agent, or the
         Arranger in connection with the preparation, negotiation, execution,
         delivery, syndication, distribution (including, without limitation, via
         the internet), review, amendment, modification, and administration of
         the Loan Documents. The Borrower also agrees to reimburse the
         Administrative Agent, the Arranger, LC Issuer and the Lenders for any
         costs, internal charges for fees and time charges of attorneys who are
         employees of the Administrative Agent, the Arranger, the LC Issuer, and
         the Lenders and out-of-pocket expenses (including attorneys' fees) paid
         or incurred by the Administrative Agent, the Arranger, LC Issuer or any
         Lender in connection with the collection and enforcement of the Loan
         Documents. Expenses being reimbursed by the Borrower under this Section
         include, without limitation costs and expenses incurred in connection
         with the Reports described in the following sentence. The Borrower
         acknowledges that from time to time Bank One may prepare and may
         distribute to the Lenders (but shall have no obligation or duty to
         prepare or to distribute to the Lenders) certain audit reports (the
         "Reports") pertaining to the Borrower's assets for internal use
         by Bank One from information

                                       51

<PAGE>

         furnished to it by or on behalf of the Borrower, after Bank One has
         exercised its rights of inspection pursuant to this Agreement.

                  (ii)     THE BORROWER HEREBY FURTHER AGREES TO INDEMNIFY THE
         ADMINISTRATIVE AGENT, THE ARRANGER, LC ISSUER, EACH LENDER, THEIR
         RESPECTIVE AFFILIATES, AND EACH OF THEIR DIRECTORS, OFFICERS AND
         EMPLOYEES AGAINST ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS,
         LIABILITIES AND EXPENSES (INCLUDING, WITHOUT LIMITATION, ALL EXPENSES
         OF LITIGATION OR PREPARATION THEREFOR WHETHER OR NOT THE ADMINISTRATIVE
         AGENT, THE ARRANGER, LC ISSUER, ANY LENDER OR ANY AFFILIATE IS A PARTY
         THERETO) WHICH ANY OF THEM MAY PAY OR INCUR ARISING OUT OF OR RELATING
         TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE TRANSACTIONS
         CONTEMPLATED HEREBY OR THE DIRECT OR INDIRECT APPLICATION OR PROPOSED
         APPLICATION OF THE PROCEEDS OF ANY CREDIT EXTENSION HEREUNDER EXCEPT TO
         THE EXTENT THAT THEY ARE DETERMINED IN A FINAL NON-APPEALABLE JUDGMENT
         BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM THE GROSS
         NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT OF THE PARTY SEEKING
         INDEMNIFICATION; PROVIDED HOWEVER, THAT IN NO EVENT SHALL THE BORROWER
         BE LIABLE UNDER THIS SECTION 9.6 FOR ANY LOST PROFITS OR FOR ANY
         SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES. THE OBLIGATIONS
         OF THE BORROWER UNDER THIS SECTION 9.6 SHALL SURVIVE THE TERMINATION OF
         THIS AGREEMENT.

         9.7.     Numbers of Documents. All statements, notices, closing
documents, and requests hereunder shall be furnished to the Administrative Agent
with sufficient counterparts so that the Administrative Agent may furnish one to
each of the Lenders.

         9.8.     Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

         9.9.     Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         9.10.    Nonliability of Lenders. The relationship between the Borrower
on the one hand and the Lenders, the LC Issuer and the Administrative Agent on
the other hand shall be solely that of borrower and lender. Neither the
Administrative Agent, the Arranger, the LC Issuer nor any Lender shall have any
fiduciary responsibilities to the Borrower. Neither the Administrative Agent,
the Arranger, the LC Issuer nor any Lender undertakes any responsibility to the
Borrower to review or inform the Borrower of any matter in connection with any
phase of the Borrower's business or operations. The Borrower agrees that neither
the Administrative Agent, the Arranger, the LC Issuer nor any Lender shall have
liability to the Borrower (whether sounding in

                                       52

<PAGE>

tort, contract or otherwise) for losses suffered by the Borrower in connection
with, arising out of, or in any way related to, the transactions contemplated
and the relationship established by the Loan Documents, or any act, omission or
event occurring in connection therewith, unless it is determined in a final
non-appealable judgment by a court of competent jurisdiction that such losses
resulted from the gross negligence, bad faith or willful misconduct of the party
from which recovery is sought. Neither the Administrative Agent, the Arranger,
the LC Issuer nor any Lender shall have any liability with respect to, and the
Borrower hereby waives, releases and agrees not to sue for, any special,
indirect or consequential damages suffered by the Borrower in connection with,
arising out of, or in any way related to the Loan Documents or the transactions
contemplated thereby.

         9.11.    Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrower pursuant to this Agreement in
confidence, except for disclosure (i) to its Affiliates and to other Lenders and
their respective Affiliates, (ii) to legal counsel, accountants, and other
professional advisors to such Lender or to a Transferee, (iii) to regulatory
officials, (iv) to any Person as requested pursuant to or as required by law,
regulation, or legal process, (v) to any Person in connection with any legal
proceeding to which such Lender is a party, (vi) to such Lender's direct or
indirect contractual counterparties in swap agreements or to legal counsel,
accountants and other professional advisors to such counterparties, (vii)
permitted by Section 12.4, and (viii) to rating agencies if required by such
agencies in connection with a rating relating to the Advances hereunder.

         9.12.    Nonreliance. Each Lender hereby represents that it is not
relying on or looking to any margin stock (as defined in Regulation U of the
Board of Governors of the Federal Reserve System) for the repayment of the
Credit Extensions provided for herein.

         9.13.    Disclosure. The Borrower and each Lender hereby acknowledge
and agree that Bank One and/or its Affiliates from time to time may hold
investments in, make other loans to, or have other relationships with the
Borrower and its Affiliates.

         9.14.    Survival of Prior Agreements. The rights and privileges
(excluding the confidentiality and indemnification provisions which are being
restated pursuant to this Agreement) afforded the Administrative Agent and the
Arranger in that certain commitment letter and that certain fee letter, each
dated February 11, 2003 among such Persons and Borrower, shall survive the
execution and delivery of this Agreement, and the Administrative Agent and the
Arranger shall continue to be entitled to the benefits thereof.

                                    ARTICLE X

                            THE ADMINISTRATIVE AGENT

         10.1.    Appointment; Nature of Relationship. Bank One, NA, is hereby
appointed by each of the Lenders as its contractual representative (herein
referred to as the "Administrative Agent") hereunder and under each other Loan
Document, and each of the Lenders irrevocably authorizes the Administrative
Agent to act as the contractual representative of such Lender with the rights
and duties expressly set forth herein and in the other Loan Documents. The
Administrative Agent agrees to act as such contractual representative upon the
express

                                       53

<PAGE>

conditions contained in this Article X. Notwithstanding the use of the defined
term "Administrative Agent," it is expressly understood and agreed that the
Administrative Agent shall not have any fiduciary responsibilities to any Lender
by reason of this Agreement or any other Loan Document and that the
Administrative Agent is merely acting as the contractual representative of the
Lenders with only those duties as are expressly set forth in this Agreement and
the other Loan Documents. In its capacity as the Lenders' contractual
representative, the Administrative Agent (i) does not hereby assume any
fiduciary duties to any of the Lenders, (ii) is a "representative" of the
Lenders within the meaning of "secured party" as defined in Section 9-102 of the
Uniform Commercial Code and (iii) is acting as an independent contractor, the
rights and duties of which are limited to those expressly set forth in this
Agreement and the other Loan Documents. Each of the Lenders hereby agrees to
assert no claim against the Administrative Agent on any agency theory or any
other theory of liability for breach of fiduciary duty, all of which claims each
Lender hereby waives.

         10.2.    Powers. The Administrative Agent shall have and may exercise
such powers under the Loan Documents as are specifically delegated to the
Administrative Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Administrative Agent shall have no
implied duties to the Lenders, or any obligation to the Lenders to take any
action thereunder except any action specifically provided by the Loan Documents
to be taken by the Administrative Agent.

         10.3.    General Immunity. Neither the Administrative Agent nor any of
its directors, officers, agents or employees shall be liable to the Borrower,
the Lenders or any Lender for any action taken or omitted to be taken by it or
them hereunder or under any other Loan Document or in connection herewith or
therewith except to the extent such action or inaction is determined in a final
non-appealable judgment by a court of competent jurisdiction to have arisen from
the gross negligence, bad faith or willful misconduct of such Person.

         10.4.    No Responsibility for Credit Extensions, Recitals, etc.
Neither the Administrative Agent nor any of its directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into,
or verify (a) any statement, warranty or representation made in connection with
any Loan Document or any borrowing hereunder; (b) the performance or observance
of any of the covenants or agreements of any obligor under any Loan Document,
including, without limitation, any agreement by an obligor to furnish
information directly to each Lender; (c) the satisfaction of any condition
specified in Article IV, except receipt of items required to be delivered solely
to the Administrative Agent; (d) the existence or possible existence of any
Default or Unmatured Default; (e) the validity, enforceability, effectiveness,
sufficiency or genuineness of any Loan Document or any other instrument or
writing furnished in connection therewith; (f) the value, sufficiency, creation,
perfection or priority of any Lien in any collateral security; or (g) the
financial condition of the Borrower or any guarantor of any of the Obligations
or of any of the Borrower's or any such guarantor's respective Subsidiaries. The
Administrative Agent shall have no duty to disclose to the Lenders information
that is not required to be furnished by the Borrower to the Administrative Agent
at such time, but is voluntarily furnished by the Borrower to the Administrative
Agent (either in its capacity as Administrative Agent or in its individual
capacity).

                                       54

<PAGE>

         10.5.    Action on Instructions of Lenders. The Administrative Agent
shall in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Loan Document in accordance with written
instructions signed by the Required Lenders or all Lenders, as the case may be,
and such instructions and any action taken or failure to act pursuant thereto
shall be binding on all of the Lenders. The Lenders hereby acknowledge that the
Administrative Agent shall be under no duty to take any discretionary action
permitted to be taken by it pursuant to the provisions of this Agreement or any
other Loan Document unless it shall be requested in writing to do so by the
Required Lenders. The Administrative Agent shall be fully justified in failing
or refusing to take any action hereunder and under any other Loan Document
unless it shall first be indemnified to its satisfaction by the Lenders pro rata
against any and all liability, cost and expense that it may incur by reason of
taking or continuing to take any such action.

         10.6.    Employment of Administrative Agents and Counsel. The
Administrative Agent may execute any of its duties as Administrative Agent
hereunder and under any other Loan Document by or through employees, agents, and
attorneys-in-fact and shall not be answerable to the Lenders, except as to money
or securities received by it or its authorized agents, for the default or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care. The Administrative Agent shall be entitled to advice of counsel
concerning the contractual arrangement between the Administrative Agent and the
Lenders and all matters pertaining to the Administrative Agent's duties
hereunder and under any other Loan Document.

         10.7.    Reliance on Documents; Counsel. The Administrative Agent shall
be entitled to rely upon any Note, notice, consent, certificate, affidavit,
letter, telegram, statement, paper or document believed by it to be genuine and
correct and to have been signed or sent by the proper person or persons, and, in
respect to legal matters, upon the opinion of counsel selected by the
Administrative Agent, which counsel may be employees of the Administrative
Agent.

         10.8.    Administrative Agent's Reimbursement and Indemnification. The
Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Commitments (or, if the Commitments have been
terminated, in proportion to their Commitments immediately prior to such
termination) (i) for any amounts not reimbursed by the Borrower for which the
Administrative Agent is entitled to reimbursement by the Borrower under the Loan
Documents, (ii) for any other expenses incurred by the Administrative Agent on
behalf of the Lenders, in connection with the preparation, execution, delivery,
administration and enforcement of the Loan Documents (including, without
limitation, for any expenses incurred by the Administrative Agent in connection
with any dispute between the Administrative Agent and any Lender or between two
or more of the Lenders) and (iii) for any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Administrative Agent in any way relating to or arising out
of the Loan Documents or any other document delivered in connection therewith or
the transactions contemplated thereby (including, without limitation, for any
such amounts incurred by or asserted against the Administrative Agent in
connection with any dispute between the Administrative Agent and any Lender or
between two or more of the Lenders), or the enforcement of any of the terms of
the Loan Documents or of any such other documents, provided that (i) no Lender
shall be liable for any of the foregoing to the extent any of the foregoing is
found in a final non-appealable judgment by a court of competent jurisdiction to
have resulted from the gross negligence or willful misconduct

                                       55

<PAGE>

of the Administrative Agent and (ii) any indemnification required pursuant to
Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be
paid by the relevant Lender in accordance with the provisions thereof. The
obligations of the Lenders under this Section 10.8 shall survive payment of the
Obligations and termination of this Agreement.

         10.9.    Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Unmatured
Default hereunder unless the Administrative Agent has received written notice
from a Lender or the Borrower referring to this Agreement describing such
Default or Unmatured Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent receives such a notice, the
Administrative Agent shall give prompt notice thereof to the Lenders.

         10.10.   Rights as a Lender. In the event the Administrative Agent is a
Lender, the Administrative Agent shall have the same rights and powers hereunder
and under any other Loan Document with respect to its Commitment and its Credit
Extensions as any Lender and may exercise the same as though it were not the
Administrative Agent, and the term "Lender" or "Lenders" shall, at any time when
the Administrative Agent is a Lender, unless the context otherwise indicates,
include the Administrative Agent in its individual capacity. The Administrative
Agent and its Affiliates may accept deposits from, lend money to, and generally
engage in any kind of trust, debt, equity or other transaction, in addition to
those contemplated by this Agreement or any other Loan Document, with the
Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is
not restricted hereby from engaging with any other Person.

         10.11.    Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent, the Arranger
or any other Lender and based on the financial statements prepared by the
Borrower and such other documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement and the
other Loan Documents. Each Lender also acknowledges that it will, independently
and without reliance upon the Administrative Agent, the Arranger 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 the other Loan Documents.

         10.12.   Successor Administrative Agent. The Administrative Agent may
resign at any time by giving written notice thereof to the Lenders and the
Borrower, such resignation to be effective upon the appointment of a successor
Administrative Agent or, if no successor Administrative Agent has been
appointed, 45 days after the retiring Administrative Agent gives notice of its
intention to resign. The Administrative Agent may be removed at any time with or
without cause by written notice received by the Administrative Agent from the
Required Lenders, such removal to be effective on the date specified by the
Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint, on behalf of the Borrower and the Lenders, a
successor Administrative Agent. If no successor Administrative Agent shall have
been so appointed by the Required Lenders within 30 days after the resigning
Administrative Agent's giving notice of its intention to resign, then the
resigning Administrative Agent may appoint, on behalf of the Borrower and the
Lenders, a successor Administrative Agent. Notwithstanding the previous
sentence, the Administrative Agent may at any time

                                       56

<PAGE>

without the consent of the Borrower or any Lender, appoint any of its Affiliates
which is a commercial bank as a successor Administrative Agent hereunder. If the
Administrative Agent has resigned or been removed and no successor
Administrative Agent has been appointed, the Lenders may perform all the duties
of the Administrative Agent hereunder and the Borrower shall make all payments
in respect of the Obligations to the applicable Lender and for all other
purposes shall deal directly with the Lenders. No successor Administrative Agent
shall be deemed to be appointed hereunder until such successor Administrative
Agent has accepted the appointment. Any such successor Administrative Agent
shall be a commercial bank having capital and retained earnings of at least
$1,000,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the resigning or removed Administrative Agent. Upon the
effectiveness of the resignation or removal of the Administrative Agent, the
resigning or removed Administrative Agent shall be discharged from its duties
and obligations hereunder and under the Loan Documents. After the effectiveness
of the resignation or removal of an Administrative Agent, the provisions of this
Article X shall continue in effect for the benefit of such Administrative Agent
in respect of any actions taken or omitted to be taken by it while it was acting
as the Administrative Agent hereunder and under the other Loan Documents. In the
event that there is a successor to the Administrative Agent by merger, or the
Administrative Agent assigns its duties and obligations to an Affiliate pursuant
to this Section 10.12, then the term "Prime Rate" as used in this Agreement
shall mean the prime rate, base rate or other analogous rate of the new
Administrative Agent.

         10.13.   Administrative Agent and Arranger Fees. The Borrower agrees to
pay to the Administrative Agent and the Arranger, for their respective accounts,
the fees agreed to by the Borrower, the Administrative Agent and the Arranger
pursuant to that certain letter agreement dated February 11, 2003, or as
otherwise agreed from time to time.

         10.14.   Delegation to Affiliates. The Borrower and the Lenders agree
that the Administrative Agent may delegate any of its duties under this
Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's
directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which the
Administrative Agent is entitled under Articles IX and X.

         10.15.   Co-Agents, Syndication Agent, etc. Neither any of the Lenders
identified in this Agreement as a "co-agent" nor the Syndication Agent shall
have any right, power, obligation, liability, responsibility or duty under this
Agreement other than those applicable to all Lenders as such. Without limiting
the foregoing, none of such Lenders shall have or be deemed to have a fiduciary
relationship with any Lender. Each Lender hereby makes the same acknowledgments
with respect to such Lenders as it makes with respect to the Administrative
Agent in Section 10.11.

                                       57

                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

         11.1.    Setoff. In addition to, and without limitation of, any rights
of the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender or
any Affiliate of any Lender to or for the credit or account of the Borrower may
be offset and applied toward the payment of the Obligations owing to such
Lender, whether or not the Obligations, or any part thereof, shall then be due.

         11.2.    Ratable Payments. If any Lender, whether by setoff or
otherwise, has payment made to it upon its Outstanding Credit Exposure (other
than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater
proportion than that received by any other Lender, such Lender agrees, promptly
upon demand, to purchase a portion of the Aggregate Outstanding Credit Exposure
held by the other Lenders so that after such purchase each Lender will hold its
Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Lender,
whether in connection with setoff or amounts which might be subject to setoff or
otherwise, receives collateral or other protection for its Obligations or such
amounts which may be subject to setoff, such Lender agrees, promptly upon
demand, to take such action necessary such that all Lenders share in the
benefits of such collateral ratably in proportion to their respective Pro Rata
Share of the Aggregate Outstanding Credit Exposure. In case any such payment is
disturbed by legal process, or otherwise, appropriate further adjustments shall
be made.

                                  ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         12.1.    Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns permitted hereby, except
that (i) the Borrower shall not have the right to assign its rights or
obligations under the Loan Documents without the prior written consent of each
Lender, (ii) any assignment by any Lender must be made in compliance with
Section 12.3, and (iii) any transfer by Participation must be made in compliance
with Section 12.2. Any attempted assignment or transfer by any party not made in
compliance with this Section 12.1 shall be null and void, unless such attempted
assignment or transfer is treated as a participation in accordance with Section
12.3.2. The parties to this Agreement acknowledge that clause (ii) of this
Section 12.1 relates only to absolute assignments and this Section 12.1 does not
prohibit assignments creating security interests, including, without limitation,
(x) any pledge or assignment by any Lender of all or any portion of its rights
under this Agreement and any Note to a Federal Reserve Bank or (y) in the case
of a Lender which is a Fund, any pledge or assignment of all or any portion of
its rights under this Agreement and any Note to its trustee in support of its
obligations to its trustee; provided, however, that no such pledge or assignment
creating a security interest shall release the transferor Lender from its
obligations hereunder unless and until the parties thereto have complied with
the provisions of Section 12.3. The Administrative Agent may treat the Person
which made any Credit Extension or which holds any

                                       58

<PAGE>

Note as the owner thereof for all purposes hereof unless and until such Person
complies with Section 12.3; provided, however, that the Administrative Agent may
in its discretion (but shall not be required to) follow instructions from the
Person which made any Credit Extension or which holds any Note to direct
payments relating to such Credit Extension or Note to another Person. Any
assignee of the rights to any Credit Extension or any Note agrees by acceptance
of such assignment to be bound by all the terms and provisions of the Loan
Documents. Any request, authority or consent of any Person, who at the time of
making such request or giving such authority or consent is the owner of the
rights to any Credit Extension (whether or not a Note has been issued in
evidence thereof), shall be conclusive and binding on any subsequent holder or
assignee of the rights to such Credit Extension.

         12.2.    Participations.

                  12.2.1.  Permitted Participants; Effect. Any Lender may at any
         time sell to one or more banks or other entities ("Participants")
         participating interests in any Credit Extension owing to such Lender,
         any Note held by such Lender, any Commitment of such Lender or any
         other interest of such Lender under the Loan Documents. In the event of
         any such sale by a Lender of participating interests to a Participant,
         such Lender's obligations under the Loan Documents shall remain
         unchanged, such Lender shall remain solely responsible to the other
         parties hereto for the performance of such obligations, such Lender
         shall remain the owner of its Outstanding Credit Exposure and the
         holder of any Note issued to it in evidence thereof for all purposes
         under the Loan Documents, all amounts payable by the Borrower under
         this Agreement shall be determined as if such Lender had not sold such
         participating interests, and the Borrower and the Administrative Agent
         shall continue to deal solely and directly with such Lender in
         connection with such Lender's rights and obligations under the Loan
         Documents.

                  12.2.2.  Voting Rights. Each Lender shall retain the sole
         right to approve, without the consent of any Participant, any
         amendment, modification or waiver of any provision of the Loan
         Documents other than any amendment, modification or waiver with respect
         to any Credit Extension or Commitment in which such Participant has an
         interest which forgives principal, interest, fees or any Reimbursement
         Obligation or reduces the interest rate or fees payable with respect to
         any such Credit Extension or Commitment, extends the Facility
         Termination Date, postpones any date fixed for any regularly-scheduled
         payment of principal of or interest on any Credit Extension in which
         such Participant has an interest, or any regularly-scheduled payment of
         fees on any such Credit Extension or Commitment, releases any guarantor
         of any such Credit Extension (except as otherwise permitted by Section
         8.2(v)) or releases any collateral held in the Facility LC Collateral
         Account (except in accordance with the terms hereof) or all or
         substantially all of any other collateral, if any, securing any such
         Credit Extension.

                  12.2.3.  Benefit of Setoff. The Borrower agrees that each
         Participant shall be deemed to have the right of setoff provided in
         Section 11.1 in respect of its participating interest in amounts owing
         under the Loan Documents to the same extent as if the amount of its
         participating interest were owing directly to it as a Lender under the
         Loan Documents, provided that each Lender shall retain the right of
         setoff provided in Section 11.1 with respect to the amount of
         participating interests sold to each Participant.

                                       59

<PAGE>

         The Lenders agree to share with each Participant, and each Participant,
         by exercising the right of setoff provided in Section 11.1, agrees to
         share with each Lender, any amount received pursuant to the exercise of
         its right of setoff, such amounts to be shared in accordance with
         Section 11.2 as if each Participant were a Lender. The Borrower further
         agrees that each Participant shall be entitled to the benefits of
         Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a
         Lender and had acquired its interest by assignment pursuant to Section
         12.3, provided that (i) a Participant shall not be entitled to receive
         (and the Borrower shall not be obligated to pay) any greater payment
         under Section 3.1, 3.2 or 3.5 than the Lender (or the amount that would
         be payable to the Lender) who sold the participating interest to such
         Participant would have received had it retained such interest for its
         own account, and (ii) any Participant not incorporated under the laws
         of the United States of America or any State thereof agrees to comply
         with the provisions of Section 3.5 to the same extent as if it were a
         Lender.

         12.3.    Assignments.

                  12.3.1.  Permitted Assignments. Any Lender may, at any time
         assign to one or more banks or other entities ("Purchasers") all or any
         part of its rights and obligations under the Loan Documents; provided
         however, if such assignments are of Eurodollar Loans prior to the last
         day of the Interest Period applicable thereto, the Borrower will not be
         required to pay the breakage fees, if any, associated with such
         assignment. Such assignment shall be substantially in the form of
         Exhibit C or in such other form as may be agreed to by the parties
         thereto. The consent of the Borrower, the Administrative Agent and the
         LC Issuer shall be required prior to an assignment becoming effective
         with respect to a Purchaser which is not a Lender or an Affiliate
         thereof; provided, however, that if a Default has occurred and is
         continuing, the consent of the Borrower shall not be required. Such
         consent from any of the Borrower, the Administrative Agent and the LC
         Issuer shall not be unreasonably withheld or delayed. Each such
         assignment with respect to a Purchaser which is not a Lender or an
         Affiliate thereof shall (unless each of the Borrower and the
         Administrative Agent otherwise consents) be in an amount not less than
         the lesser of (i) $5,000,000 or (ii) the remaining amount of the
         assigning Lender's Commitment (calculated as at the date of such
         assignment) or outstanding Credit Extensions (if the applicable
         Commitment has been terminated).

                  12.3.2.  Effect; Effective Date. Upon (i) delivery to the
         Administrative Agent of a notice of assignment, substantially in the
         form attached as Exhibit I to Exhibit C (a "Notice of Assignment"),
         together with any consents required by Section 12.3.1, and (ii) payment
         of a $4,000 fee to the Administrative Agent for processing such
         assignment (unless such fee is waived by the Administrative Agent),
         such assignment shall become effective on the effective date specified
         in such Notice of Assignment. The Notice of Assignment shall contain a
         representation by the Purchaser to the Administrative Agent and the
         Borrower to the effect that none of the consideration used to make the
         purchase of the Commitment and Outstanding Credit Exposure under the
         applicable assignment agreement are "plan assets" as defined under
         ERISA and that the rights and interests of the Purchaser in and under
         the Loan Documents will not be "plan assets" under ERISA. On and after
         the effective date of such assignment, such Purchaser shall for all
         purposes be a Lender party to this Agreement and any other Loan
         Document executed by or on

                                       60

<PAGE>

         behalf of the Lenders and shall have all the rights and obligations of
         a Lender under the Loan Documents, to the same extent as if it were an
         original party hereto, and no further consent or action by the
         Borrower, the Lenders or the Administrative Agent shall be required to
         release the transferor Lender with respect to the percentage of the
         Aggregate Commitment and Outstanding Credit Exposure assigned to such
         Purchaser. In the case of an assignment covering all of the assigning
         Lender's rights and obligations under this Agreement, such Lender shall
         cease to be a Lender hereunder but shall continue to be entitled to the
         benefits of, and subject to, those provisions of this Agreement and the
         other Loan Documents which survive payment of the Obligations and
         termination of the applicable agreement. Any assignment or transfer by
         a Lender of rights or obligations under this Agreement that does not
         comply with this Section 12.3 shall be treated for purposes of this
         Agreement as a sale by such Lender of a participation in such rights
         and obligations in accordance with Section 12.2. Upon the consummation
         of any assignment to a Purchaser pursuant to this Section 12.3.2, the
         transferor Lender, the Administrative Agent and the Borrower shall, if
         the transferor Lender or the Purchaser desires that its Loans be
         evidenced by Notes, make appropriate arrangements so that new Notes or,
         as appropriate, replacement Notes are issued to such transferor Lender
         and new Notes or, as appropriate, replacement Notes, are issued to such
         Purchaser, in each case in principal amounts reflecting their
         respective Commitments, as adjusted pursuant to such assignment.

                  12.3.3.  Consents. The consent of the Borrower shall be
         required prior to an assignment becoming effective unless the Purchaser
         is a Lender, an Affiliate of a Lender or an Approved Fund, provided
         that the consent of the Borrower shall not be required if a Default has
         occurred and is continuing. The consent of the Administrative Agent and
         LC Issuer shall be required prior to an assignment becoming effective
         unless the Purchaser is a Lender with a Revolving Commitment (in the
         case of an assignment of a Revolving Commitment) or is an Affiliate of
         a Lender or an Approved Fund. Any consent required under this Section
         12.3.3 shall not be unreasonably withheld or delayed.

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

         12.4.    Dissemination of Information. The Borrower authorizes each
Lender to disclose to any Participant or Purchaser or any other Person acquiring
an interest in the Loan Documents by operation of law (each a "Transferee") and
any prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries,

                                       61

including without limitation any information contained in any Reports; provided
that each Transferee and prospective Transferee agrees to be bound by Section
9.11 of this Agreement.

         12.5.    Tax Treatment. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.5(iv).

any Lender may each change the address for service of notice upon it by a notice
in writing to the other parties hereto.

         the Borrower or any Lender, nor any of the terms or provisions
         contained herein, shall be construed to be a payment on or with respect
         to the Existing Indebtedness or any accrued interest thereon. Without
         limiting the foregoing, the Borrower and each of its

         shall continue to be maintained by the Lenders until the last day of
         the current Interest Period therefor (except to the extent prepaid or
         converted by the Borrower prior to such date).
