means "from and including," "to" means "to but excluding," and "through" means
"through and including"; and

                  1.2.10 Shall; Will.

                  references to "shall" and "will" are intended to have the same
meaning.

            1.3 Accounting Principles.

            Except as otherwise provided in this Agreement, all computations and
determinations as to accounting or financial matters and all financial
statements to be delivered pursuant to this Agreement shall be made and prepared
in accordance with GAAP (including principles of consolidation where
appropriate), and all accounting or financial terms shall have the meanings
ascribed to such terms by GAAP; provided, however, that all accounting terms
used in Section 7.2 [Negative Covenants] (and all defined terms used in the
definition of any accounting term used in Section 7.2), as applied to the
Borrower and its Subsidiaries shall have the meaning given to such terms (and
defined terms) under GAAP as in effect on the Restatement Effective Date applied
on a basis consistent with those used in preparing the Historical Statements
referred to in Section 5.1.7(i) [Historical Statements]. In the event of any
change after the Restatement Effective Date in GAAP, and if such change would
result in the inability to determine compliance with the financial covenants set
forth in Section 7.2 based upon the Borrower's regularly prepared financial
statements by reason of the preceding sentence, then the parties hereto agree to
endeavor, in good faith, to agree upon an amendment to this Agreement that would
adjust such financial covenants in a manner that would not affect the substance
thereof, but would allow compliance therewith to be determined in accordance
with the Borrower's financial statements at that time.

            2. REVOLVING CREDIT AND SWING LOAN FACILITIES

            2.1 Revolving Credit Commitments.

                  2.1.1 Revolving Credit Loans.

                  Subject to the terms and conditions hereof and relying upon
the representations and warranties herein set forth, each Bank severally agrees
to make Revolving Credit Loans to the Borrower at any time or from time to time
on or after the date hereof to the Expiration Date, provided that after giving
effect to such Revolving Credit Loan the aggregate amount of Revolving Credit
Loans from such Bank shall not exceed such Bank's Revolving Credit Commitment
minus such Bank's Revolving Credit Ratable Share of the Letters of Credit
Outstanding provided further that the Revolving Facility Usage at any time,
shall not exceed the Revolving Credit Commitments of all the Banks. Within such
limits of time and amount, and subject to the other provisions of this
Agreement, the Borrower may borrow, repay and reborrow pursuant to this Section
2.1.1.

                  2.1.2 Swing Loan Commitment.

                  Subject to the terms and conditions hereof and relying upon
the representations and warranties herein set forth, PNC Bank agrees to make
Swing Loans (the "Swing Loans") to the Borrower at any time or from time to time
after the date hereof to, but not including, the Expiration Date, in an
aggregate principal amount of up to but not in excess of $40,000,000 (the "Swing
Loan Commitment"), provided that the Revolving Facility Usage at any time, shall
not exceed the Revolving Credit Commitments of all the Banks. Within such limits
of time and amount and subject to the other provisions of this Agreement, the
Borrower may borrow, repay and reborrow pursuant to this Section 2.1.2.

            2.2 Nature of Banks' Obligations With Respect to Revolving Credit
Loans.

            Each Bank shall be obligated to participate in each request for
Revolving Credit Loans pursuant to Section 2.4 [Loan Requests] in accordance
with its Revolving Credit Ratable Share. The aggregate of each Bank's Revolving
Credit Loans outstanding hereunder to the Borrower at any time shall never
exceed its Revolving Credit Commitment minus its Revolving Credit Ratable Share
of the Letters of Credit Outstanding. The obligations of each Bank hereunder are
several. The failure of any Bank to perform its obligations hereunder shall not
affect the Obligations of the Borrower to any other party nor shall any other
party be liable for the failure of such Bank to perform its obligations
hereunder. The Banks shall have no obligation to make Revolving Credit Loans
hereunder on or after the Expiration Date.

            2.3 Fees; Commitment Fee.

                  Accruing from the date hereof until the Expiration Date, the
Borrower agrees to pay to the Administrative Agent for the account of each Bank,
as consideration for such Bank's Revolving Credit Commitment hereunder, a
nonrefundable commitment fee (the "Commitment Fee") equal to the Applicable
Commitment Fee Rate computed (on the basis of a year of 365 or 366 days, as the
case may be, and actual days elapsed) on the average daily

                                     - 39 -
<PAGE>

difference between the amount of (i) such Bank's Revolving Credit Commitment as
the same may be constituted from time to time (for purposes of this computation,
PNC Bank's Swing Loans shall not be deemed to be borrowed amounts under its
Revolving Credit Commitment), and (ii) the sum of such Bank's Revolving Credit
Loans outstanding plus its Revolving Credit Ratable Share of the Letters of
Credit Outstanding. All Commitment Fees shall be payable in arrears on the first
Business Day of each July, October, January and April after the date hereof and
on the Expiration Date or upon acceleration of the Loans.

            2.4 Loan Requests.

                  2.4.1 Committed Loan Requests.

                  Except as otherwise provided herein, the Borrower may from
time to time prior to the Expiration Date request the Banks to make Revolving
Credit Loans, or renew or convert the Interest Rate Option applicable to
existing Revolving Credit Loans pursuant to Section 3.2 [Interest Periods], by
delivering to the Administrative Agent, not later than 10:00 a.m., Pittsburgh
time, (i) three (3) Business Days prior to the proposed Borrowing Date with
respect to the making of Revolving Credit Loans to which the Euro-Rate Option
applies or the conversion to or the renewal of the Euro-Rate Option for any
Revolving Credit Loans; and (ii) one (1) Business Day prior to either the
proposed Borrowing Date with respect to the making of a Revolving Credit Loan to
which the Base Rate Option applies or the last day of the preceding Interest
Period with respect to the conversion to the Base Rate Option for any Revolving
Credit Loan, of a duly completed Committed Loan Request therefor substantially
in the form of Exhibit 2.4.1 or a Committed Loan Request by telephone
immediately confirmed in writing by letter, facsimile or telex in the form of
such Exhibit, it being understood that the Administrative Agent may rely on the
authority of any individual making such a telephonic request without the
necessity of receipt of such written confirmation. Each Committed Loan Request
shall be irrevocable and shall specify (i) the proposed Borrowing Date; (ii) the
aggregate amount of the proposed Revolving Credit Loans comprising each
Borrowing Tranche, which shall be in integral multiples of $5,000,000 and not
less than $10,000,000 for each Borrowing Tranche to which the Euro-Rate Option
applies and in integral multiples of $1,000,000 and not less than the lesser of
$5,000,000 or the maximum amount available for Borrowing Tranches to which the
Base Rate Option applies; (iii) whether the Euro-Rate Option or Base Rate Option
shall apply to the proposed Revolving Credit Loans comprising an applicable
Borrowing Tranche; and (iv) in the case of a Borrowing Tranche to which the
applicable Euro-Rate Option applies, an appropriate Interest Period for the
Loans comprising such Borrowing Tranche.

                  2.4.2 Swing Loan Requests.

                  Except as otherwise provided herein, the Borrower may from
time to time prior to the Expiration Date request PNC Bank to make a Swing Loan
by delivery to PNC Bank, not later than 12:00 noon Pittsburgh time, on the
proposed Borrowing Date of a duly completed request therefor substantially in
the form of Exhibit 2.4.2 hereto or a request by telephone immediately confirmed
in writing by letter, facsimile or telex (each, a "Swing Loan Request"), it
being understood that PNC Bank may rely on the authority of any individual
making such a telephonic request without the necessity of receipt of such
written confirmation. Each Swing

                                     - 40 -
<PAGE>

Loan Request shall be irrevocable and shall specify (i) the proposed Borrowing
Date, (ii) the term of the proposed Swing Loan, which shall be no less than one
day and no longer than three days, and (iii) the principal amount of such Swing
Loan, which shall be not less than $1,000,000 and shall be an integral multiple
of $100,000.

            2.5 Making Revolving Credit Loans and Swing Loans.

            The Administrative Agent shall, promptly after receipt by it of a
Committed Loan Request pursuant to Section 2.4.1 [Committed Loan Requests],
notify the Banks of its receipt of such Committed Loan Request specifying: (i)
the proposed Borrowing Date and the time and method of disbursement of the
Revolving Credit Loans requested thereby; (ii) the amount and type of each such
Revolving Credit Loan and the applicable Interest Period (if any); and (iii) the
apportionment among the Banks of such Revolving Credit Loans as determined by
the Administrative Agent in accordance with Section 2.2 [Nature of Banks'
Obligations, etc.]. Each Bank shall remit the principal amount of each Revolving
Credit Loan to the Administrative Agent such that the Administrative Agent is
able to, and the Administrative Agent shall, to the extent the Banks have made
funds available to it for such purpose and subject to Section 6.2 [Each
Additional Loan or Letter of Credit], fund such Revolving Credit Loans to the
Borrower in U.S. Dollars and immediately available funds at the Principal Office
prior to 2:00 p.m., Pittsburgh time, on the applicable Borrowing Date, provided
that if any Bank fails to remit such funds to the Administrative Agent in a
timely manner, the Administrative Agent may elect in its sole discretion to fund
with its own funds the Revolving Credit Loans of such Bank on such Borrowing
Date, and such Bank shall be subject to the repayment obligation in Section 9.16
[Availability of Funds].

                  2.5.1 Making Swing Loans.

                  PNC Bank shall, after receipt by it of a Swing Loan Request
pursuant to Section 2.4.2, fund such Swing Loan to the Borrower in U.S. Dollars
and immediately available funds at the Principal Office prior to 3:00 p.m.,
Pittsburgh time, on the Borrowing Date. Swing Loans shall bear interest at the
Offered Rate Option.

            2.6 Swing Loan Note.

            The obligation of the Borrower to repay the unpaid principal amount
of the Swing Loans made to it by PNC Bank together with interest thereon shall
be evidenced by a demand promissory note of the Borrower dated the Closing Date
in substantially the form attached hereto as Exhibit 1.1(S) payable to the order
of PNC Bank in a face amount equal to the Swing Loan Commitment of PNC Bank.

            2.7 Use of Proceeds.

            On and after the Restatement Effective Date, the proceeds of the
Loans shall be used to continue and refinance the indebtedness under the
revolving credit facility of the Original Credit Agreement, to repay the term
loans under the Original Credit Agreement, and for general corporate purposes
and in accordance with Section 7.1.9 [Use of Proceeds]. Subject to Section
7.2.14 (v), proceeds of Loans may be used by the Borrower to make loans to or
investments in

                                     - 41 -
<PAGE>

Arch Western and Letters of Credit may be issued for the benefit or the use of
any member of the Arch Western Group.

            2.8 Borrowings to Repay Swing Loans.

            PNC Bank may, at its option, exercisable at any time for any reason
whatsoever, demand repayment of the Swing Loans, and each Bank shall make
available to the Administrative Agent, on behalf of PNC Bank, an amount equal to
such Bank's Revolving Credit Ratable Share of the aggregate principal amount of
the outstanding Swing Loans, plus, if PNC Bank so requests, accrued interest
thereon, provided that no Bank shall be obligated in any event to make Revolving
Credit Loans in excess of its Revolving Credit Commitment minus its Revolving
Credit Ratable Share of the Letters of Credit Outstanding. Revolving Credit
Loans made pursuant to the preceding sentence shall bear interest at the Base
Rate Option and shall be deemed to have been properly requested in accordance
with Section 2.4.1 without regard to any of the requirements of that provision.
PNC Bank shall provide notice to all of the Banks (which may be telephonic or
written notice by letter, facsimile or telex) of the amount of such Bank's
Revolving Credit Ratable Share of the aggregate principal amount of the
outstanding Swing Loans, plus accrued interest thereon, to be made available to
the Administrative Agent on behalf of PNC Bank under this Section 2.8. The
Administrative Agent shall promptly provide to each Bank notice of the
apportionment thereof among the Banks, and the Banks shall be unconditionally
obligated to fund such amount (whether or not the conditions specified in
Section 2.4.1 are then satisfied) by the time PNC Bank so requests, which shall
not be earlier than 3:00 p.m., Pittsburgh time, on the Business Day next after
the date the Banks receive such notice of apportionment from the Administrative
Agent.

            2.9 Letter of Credit Subfacility.

                  2.9.1 Issuance of Letters of Credit.

                  Borrower may request the issuance of a letter of credit (each
a "Letter of Credit") on behalf of itself or another Loan Party by delivering or
having such other Loan Party deliver to the Issuing Bank selected by the
Borrower (with a copy to the Administrative Agent) a completed application and
agreement for letters of credit in such form as such Issuing Bank may specify
from time to time by no later than 10:00 a.m., Pittsburgh time, at least three
(3) Business Days, or such shorter period as may be agreed to by the selected
Issuing Bank, in advance of the proposed date of issuance. Each Letter of Credit
shall be either a Standby Letter of Credit or a Commercial Letter of Credit.
Subject to the terms and conditions hereof and in reliance on the agreements of
the other Banks set forth in this Section 2.9.1, the Issuing Bank will issue a
Letter of Credit provided that each Letter of Credit shall (A) have a maximum
maturity of twelve (12) Months from the date of issuance, and (B) in no event
expire later than ten (10) Business Days prior to the Expiration Date and
provided that in no event shall (i) the Letters of Credit Outstanding exceed, at
any one time, $200,000,000, (ii) Reimbursement Obligations (contingent or
otherwise) exceed, at any one time, $10,000,000, with respect to Commercial
Letters of Credit, or (iii) the Revolving Facility Usage exceed, at any one
time, the Revolving Credit Commitments. Subject to Section 7.2.14(v), Letters of
Credit may be issued for the benefit or the use of, directly or indirectly, any
member of the Arch Western Group. No Letters of Credit

                                     - 42 -
<PAGE>

shall be issued for the benefit or the use of, directly or indirectly, any
Significant Subsidiary which is a member of the Arch Coal Group which is not a
party to the Guaranty Agreement until such time as such Significant Subsidiary
has joined the Guaranty Agreement in accordance with Section 10.18 [Requirements
for Significant Subsidiaries]. Schedule 2.9.1 sets forth letters of credit,
issued by PNC Bank as an "Issuing Bank" under the Original Credit Agreement,
which are outstanding as of the Restatement Effective Date (the "Existing
Letters of Credit"). It is expressly agreed that the Existing Letters of Credit
are Letters of Credit under this Agreement.

                  2.9.2 Letter of Credit Fees.

                  Subject to the terms and conditions of this Agreement, any
Issuing Bank selected by the Borrower shall issue the requested Letter of
Credit. The Borrower shall also pay to the Issuing Bank for the Issuing Bank's
sole account the Issuing Bank's then-in-effect customary fees and administrative
expenses payable with respect to the Letters of Credit as the Issuing Bank may
generally charge or incur from time to time in connection with the issuance,
maintenance, modification (if any), assignment or transfer (if any),
negotiation, and administration of Letters of Credit. The Borrower shall pay (i)
to the Administrative Agent for the ratable account of the Banks a fee (the
"Letter of Credit Fee") equal to the Applicable Letter of Credit Fee Rate then
in effect (computed on the basis of a year of 360 days and actual days elapsed)
and (ii) to the Administrative Agent for its own account a fronting fee equal to
0.125% per annum (computed on the basis of a year of 360 days and actual days
elapsed), which fees shall be computed on the daily average Letters of Credit
Outstanding and shall be payable quarterly in arrears commencing with the first
Business Day of each January, April, July and October following issuance of each
Letter of Credit and on the Expiration Date.

                  2.9.3 Participations in Letters of Credit; Disbursements,
Reimbursement.

                        2.9.3.1 Immediately upon issuance of each Letter of
Credit, and without further action, each Bank shall be deemed to, and hereby
agrees that it shall, have irrevocably purchased, for such Bank's own account
and risk, from the applicable Issuing Bank an individual participation interest
in such Letter of Credit in an amount equal to such Bank's Revolving Credit
Ratable Share of the maximum amount which is or at any time may become available
to be drawn thereunder, and each Bank shall be responsible to reimburse such
Issuing Bank immediately for its Revolving Credit Ratable Share of any
disbursement under any Letter of Credit which has not been reimbursed by
Borrower in accordance with Section 2.9.3.2 by making its Revolving Credit
Ratable Share of the Revolving Credit Loans referred to in Section 2.9.3.3
available to the Administrative Agent for the account of the Issuing Bank. Upon
the request of any Bank and no less frequently than once in each calendar month,
the Administrative Agent shall notify each Bank of the amount of such Bank's
participation in Letters of Credit.

                        2.9.3.2 In the event of any request for a drawing under
a Letter of Credit by the beneficiary or transferee thereof, the Issuing Bank
will promptly notify the Borrower and the Administrative Agent. Provided that it
shall have received such notice, the Borrower shall reimburse (such obligation
to reimburse the Issuing Bank shall sometimes be referred to as a "Reimbursement
Obligation") the Administrative Agent on behalf of the Issuing

                                     - 43 -
<PAGE>

Bank prior to 12:00 noon, Pittsburgh time, on each date that an amount is paid
by the Issuing Bank under any Letter of Credit (each such date, a "Drawing
Date") in an amount equal to the amount so paid by the Issuing Bank. In the
event the Borrower fails to reimburse the Administrative Agent on behalf of the
Issuing Bank for the full amount of any drawing under any Letter of Credit by
12:00 noon, Pittsburgh time, on the Drawing Date, the Issuing Bank will promptly
notify the Administrative Agent and each Bank thereof, and the Borrower shall be
deemed to have requested that Revolving Credit Loans be made by the Banks under
the Base Rate Option to be disbursed on the Drawing Date under such Letter of
Credit. Any notice given by the Administrative Agent or the Issuing Bank
pursuant to this Section 2.9.3.2 may be oral if immediately confirmed in
writing; provided that the lack of such an immediate confirmation shall not
affect the conclusiveness or binding effect of such notice.

                        2.9.3.3 Each Bank shall upon any notice pursuant to
Section 2.9.3.2 make available to the Administrative Agent, on behalf of the
Issuing Bank, an amount in immediately available funds equal to its Revolving
Credit Ratable Share of the amount of the drawing, whereupon the participating
Banks shall each be deemed to have made a Revolving Credit Loan under the Base
Rate Option to the Borrower in that amount. If any Bank so notified fails to
make available to the Administrative Agent for the account of the Issuing Bank
the amount of such Bank's Revolving Credit Ratable Share of such amount by no
later than 2:00 p.m., Pittsburgh time, on the Drawing Date, then interest shall
accrue on such Bank's obligation to make such payment from the Drawing Date to
the date on which such Bank makes such payment (i) at a rate per annum equal to
the Federal Funds Effective Rate during the first three days following the
Drawing Date and (ii) at a rate per annum equal to the rate applicable to
Revolving Credit Loans under the Base Rate Option on and after the fourth day
following the Drawing Date; provided, however, that in the event that a Bank
does not timely receive notice in order to so fund its Revolving Credit Ratable
Share to the Administrative Agent prior to 2:00 p.m., Pittsburgh time, on the
Drawing Date, interest, with respect to the Drawing Date only, shall not accrue
as previously described in this sentence. The Issuing Bank will promptly give
notice to the Administrative Agent and each other Bank of the occurrence of the
Drawing Date, but failure of the Issuing Bank to give any such notice on the
Drawing Date or in sufficient time to enable any Bank to effect such payment on
such date shall not relieve such Bank from its obligation under this Section
2.9.3.3.

                  2.9.4 Documentation.

                  Each Loan Party agrees to be bound by the terms of the
selected Issuing Bank's application and agreement for letters of credit and the
Issuing Bank's written regulations and customary practices relating to letters
of credit, though such interpretation may be different from such Loan Party's
own. In the event of a conflict between such application or agreement and this
Agreement, this Agreement shall govern. It is understood and agreed that, except
in the case of gross negligence or willful misconduct, neither the Agents nor
any Issuing Bank shall be liable for any error, negligence and/or mistakes,
whether of omission or commission, in following any Loan Party's instructions or
those contained in the Letters of Credit or any modifications, amendments or
supplements thereto.

                  2.9.5 Determinations to Honor Drawing Requests.

                  In determining whether to honor any request for drawing under
any Letter of Credit by the beneficiary thereof, the Issuing Bank shall be
responsible only to determine that the documents and certificates required to be
delivered under such Letter of Credit have been delivered and that they comply
on their face with the requirements of such Letter of Credit.

                  2.9.6 Nature of Participation and Reimbursement Obligations.

                  Each Bank's obligation in accordance with this Agreement to
participate in Letters of Credit and make the Revolving Credit Loans, as
contemplated by Section 2.9.3 [Participations in Letters of Credit;
Disbursements, Reimbursement], as a result of a drawing under a Letter of
Credit, and the Obligations of the Borrower to reimburse the Issuing Bank upon a
draw under a Letter of Credit, shall be absolute, unconditional and irrevocable,
and shall be performed strictly in accordance with the terms of this Section
2.9.6 under all circumstances, including the following circumstances:

                        (i) any set-off, counterclaim, recoupment, defense or

forth in this Agreement for the making of a Revolving Credit Loan, it being
acknowledged that such conditions are not required for the making of a Revolving
Credit Loan under Section 2.9.3 [Participations in Letters of Credit;
Disbursements; Reimbursement];

                        (iii) any lack of validity or enforceability of any
Letter of Credit;

                        (iv) any claim of breach of warranty that might be made
by any Loan Party or any Bank against any beneficiary of a Letter of Credit, or
the existence of any claim, set-off, recoupment, counterclaim, crossclaim,
defense or other right which any Loan Party or any Bank may have at any time
against a beneficiary, successor beneficiary, or any transferee or assignee of
any Letter of Credit or the proceeds thereof (or any Persons for whom any such
transferee may be acting), either Agent, any Issuing Bank, or any Bank or any
other Person or, whether in connection with this Agreement, the transactions
contemplated herein or any unrelated transaction (including any underlying
transaction between any Loan Party or Subsidiaries of a Loan Party and the
beneficiary for which any Letter of Credit was procured);

any defect in or forgery of any signature or endorsement on) or the form of or
lack of validity, sufficiency, accuracy, enforceability or genuineness of any
draft, demand, instrument, certificate or other document presented under or in
connection with any Letter of Credit or any fraud or

property or provisions of services relating to a Letter of Credit, in each case
even if the Issuing Bank has been notified thereof;

                        (vi) payment by any Issuing Bank under any Letter of
Credit against presentation of a demand, draft or certificate or other document
which does not comply with the terms of such Letter of Credit;

                        (vii) the solvency of, or any acts or omissions by, any
beneficiary of any Letter of Credit, or any other Person having a role in any
transaction or obligation relating to a Letter of Credit, or the existence,
nature, quality, quantity, condition, value or other characteristic of any
property or services relating to a Letter of Credit;

                        (viii) any failure by the Issuing Bank to issue any
Letter of Credit in the form requested by any Loan Party, unless the Issuing
Bank has received written notice from such Loan Party of such failure within
three Business Days after the Issuing Bank shall have furnished such Loan Party
a copy of such Letter of Credit and such error is material and no drawing has
been made thereon prior to receipt of such notice;

                        (ix) any adverse change in the business, operations,

whether or not similar to any of the foregoing.

                  2.9.7 Indemnity.

                  In addition to amounts payable as provided in Section 9.5
[Reimbursement and Indemnification of Agents by the Borrower], the Borrower
hereby agrees to protect, indemnify, pay and save harmless the Agents and each
Issuing Bank from and against any and all claims, demands, liabilities, damages,
taxes, penalties, interest, judgments, losses, costs, charges and expenses
(including reasonable fees, expenses and disbursements of counsel) which any
Agent or any Issuing Bank may incur or be subject to as a consequence, direct or
indirect, of (i) the issuance of any Letter of Credit, other than as a result of
(A) the gross negligence or

                                     - 46 -

willful misconduct of any Agent or any Issuing Bank as determined by a final
judgment of a court of competent jurisdiction or (B) subject to the following
clause (ii), the wrongful dishonor by an Issuing Bank of a proper demand for
payment made under any Letter of Credit, or (ii) the failure of an Issuing Bank
to honor a drawing under any such Letter of Credit as a result of any act or
omission, whether rightful or wrongful, of any present or future de jure or de
facto government or governmental authority (all such acts or omissions herein
called "Governmental Acts").

                  2.9.8 Liability for Acts and Omissions.

                  As between any Loan Party, each Issuing Bank and the Agents,
such Loan Party assumes all risks of the acts and omissions of, or misuse of the
Letters of Credit by, the respective beneficiaries of such Letters of Credit. In
furtherance and not in limitation of the foregoing, neither any Agent nor any
Issuing Bank shall be responsible for any of the following including any losses
or damages to any Loan Party or other Person or property relating therefrom: (i)
the form, validity, sufficiency, accuracy, genuineness or legal effect of any
document submitted by any party in connection with the application for an
issuance of any such Letter of Credit, even if it should in fact prove to be in
any or all respects invalid, insufficient, inaccurate, fraudulent or forged
(even if the Issuing Bank shall have been notified thereof); (ii) the validity
or sufficiency of any instrument transferring or assigning or purporting to
transfer or assign any such Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (iii) the failure of the beneficiary of
any such Letter of Credit, or any other party to which such Letter of Credit may
be transferred, to comply fully with any conditions required in order to draw
upon such Letter of Credit or any other claim of any Loan Party against any
beneficiary of such Letter of Credit, or any such transferee, or any dispute
between or among any Loan Party and any beneficiary of any Letter of Credit or
any such transferee; (iv) errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telex or
otherwise, whether or not they be in cipher; (v) errors in interpretation of
technical terms; (vi) any loss or delay in the transmission or otherwise of any
document required in order to make a drawing under any such Letter of Credit or
of the proceeds thereof; (vii) the misapplication by the beneficiary of any such
Letter of Credit of the proceeds of any drawing under such Letter of Credit; or
(viii) any consequences arising from causes beyond the control of any Issuing
Bank or any Agent, including any Governmental Acts, and none of the above shall
affect or impair, or prevent the vesting of, any of the Agents' rights or powers
hereunder or of any of the rights or powers hereunder of any Issuing Bank.
Nothing in the preceding sentence shall: (x) relieve any Agent from liability
for such Agent's gross negligence or willful misconduct in connection with
actions or omissions described in such clauses (i) through (viii) of such
sentence, or (y) relieve any Issuing Bank from liability for such Issuing Bank's
gross negligence or willful misconduct in connection with actions or omissions
described in such clauses (i) through (viii) of such sentence. In no event shall
any Issuing Bank or any Agent be liable to any Loan Party for any indirect,
consequential, incidental, punitive, exemplary or special damages or expenses
(including without limitation attorneys' fees), or for any damages resulting
from any change in the value of any property relating to a Letter of Credit.

                  Without limiting the generality of the foregoing, each Issuing
Bank and the Agents (i) may rely on any oral or other communication believed in
good faith by any Issuing

                                     - 47 -
<PAGE>

Bank or any Agent to have been authorized or given by or on behalf of the
applicant for a Letter of Credit, (ii) may honor any presentation if the
documents presented appear on their face substantially to comply with the terms
and conditions of the relevant Letter of Credit; (iii) may honor a previously
dishonored presentation under a Letter of Credit, whether such dishonor was
pursuant to a court order, to settle or compromise any claim of wrongful
dishonor, or otherwise, and shall be entitled to reimbursement to the same
extent as if such presentation had initially been honored, together with any
interest paid by the Agent; (iv) may honor any drawing that is payable upon
presentation of a statement advising negotiation or payment, upon receipt of
such statement (even if such statement indicates that a draft or other document
is being delivered separately), and shall not be liable for any failure of any
such draft or other document to arrive, or to conform in any way with the
relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming
that it rightfully honored under the laws or practices of the place where such
bank is located; and (vi) may settle or adjust any claim or demand made on the
Agent in any way related to any order issued at the applicant's request to an
air carrier, a letter of guarantee or of indemnity issued to a carrier or any
similar document (each an "Order") and honor any drawing in connection with any
Letter of Credit that is the subject to such Order, notwithstanding that any
drafts or other documents presented in connection with such Letter of Credit
fail to conform in any way with such Letter of Credit.

                  In furtherance and extension and not in limitation of the
specific provisions set forth above, any action taken or omitted by any Agent or
any Issuing Bank under or in connection with the Letters of Credit issued by it
or any documents and certificates delivered thereunder, if taken or omitted in
good faith, shall not put any Agent or any Issuing Bank under any resulting
liability to the Borrower or any other Bank.

                        3. INTEREST RATES

            3.1 Interest Rate Options.

            The Borrower shall pay interest in respect of the outstanding unpaid
principal amount of the Revolving Credit Loans as selected by it from the Base
Rate Option or Euro-Rate Option set forth below applicable to the Revolving
Credit Loans, it being understood that, subject to the provisions of this
Agreement, the Borrower may select different Interest Rate Options and different
Interest Periods to apply simultaneously to the Revolving Credit Loans
comprising different Borrowing Tranches and may convert to or renew one or more
Interest Rate Options with respect to all or any portion of the Revolving Credit
Loans comprising any Borrowing Tranche, provided that there shall not be at any
one time outstanding more than nine (9) Borrowing Tranches in the aggregate
among all of the Revolving Credit Loans accruing interest at a Euro-Rate Option,
and provided further that only the Offered Rate Option shall apply to the Swing
Loans. If at any time the designated rate applicable to any Loan exceeds such
Lender's highest lawful rate, the rate of interest on such Loan shall be limited
to such Lender's highest lawful rate.

                                     - 48 -
<PAGE>

                  3.1.1 Interest Rate Options.

                  The Borrower shall have the right to select from the following
Interest Rate Options applicable to the Revolving Credit Loans (subject to the
provisions above regarding Swing Loans):

                        (i) Base Rate Option: A fluctuating rate per annum
(computed on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed) equal to the Base Rate plus the Applicable Margin, such
interest rate to change automatically from time to time effective as of the
effective date of each change in the Base Rate; or

                        (ii) Euro-Rate Option: A rate per annum (computed on the
basis of a year of 360 days and actual days elapsed) equal to the Euro-Rate plus
the Applicable Margin.

Notwithstanding the foregoing, on the Restatement Effective Date, the Applicable
Margin shall be the amount determined in accordance with the parameters set
forth in Schedule 1.1(A) but shall be no less than the amount set forth in the
pricing grid under Level III thereof. It is expressly agreed that after the
Restatement Effective Date, the Applicable Margin shall be determined, based
upon the applicable Debt Rating in effect from time to time, as set forth in
Schedule 1.1(A).

                  3.1.2 Rate Quotations.

                  The Borrower may call the Administrative Agent on or before
the date on which a Committed Loan Request is to be delivered to receive an
indication of the rates then in effect as to Revolving Credit Loans, but it is
acknowledged that such projection shall not be binding on the Administrative
Agent or the Banks nor affect the rate of interest which thereafter is actually
in effect when the election is made.

                  3.1.3 Change in Fees or Interest Rates.

                  If the Applicable Margin or Applicable Commitment Fee Rate is
increased or reduced with respect to any period for which the Borrower has
already paid interest or Commitment Fees, the Administrative Agent shall
recalculate the additional interest or Commitment Fees due from or to the
Borrower and shall, within fifteen (15) Business Days after the Borrower
notifies the Administrative Agent of such increase or decrease, give the
Borrower and the Banks notice of such recalculation.

                        3.1.3.1 Any additional interest or Commitment Fees due
from the Borrower shall be paid to the Administrative Agent for the account of
the Banks on the next date on which an interest or fee payment is due; provided,
however, that if there are no Loans outstanding or if the Loans are due and
payable, such additional interest or Commitment Fees shall be paid promptly
after receipt of written request for payment from the Administrative Agent.

                                     - 49 -
<PAGE>

                        3.1.3.2 Any interest or Commitment Fees refund due to
the Borrower shall be credited against payments otherwise due from the Borrower
on the next interest or fee payment due date or, if the Loans have been repaid
and the Banks are no longer committed to lend under this Agreement, the Banks
shall pay the Administrative Agent for the account of the Borrower such interest
or Commitment Fee refund not later than five (5) Business Days after written
notice from the Administrative Agent to the Banks.

            3.2 Interest Periods.

            At any time when the Borrower shall select, convert to or renew a
Euro-Rate Option, the Borrower shall notify the Administrative Agent thereof at
least three (3) Business Days prior to the effective date of such Euro-Rate
Option by delivering a Committed Loan Request. The notice shall specify an
interest period (the "Interest Period") during which such Euro-Rate Option shall
apply, such Interest Period to be one, two, three or six Months. The following
provisions shall apply to any selection of, renewal of, or conversion to a
Euro-Rate Option:

                  3.2.1 Ending Date and Business Day.

                  any Interest Period which would otherwise end on a date which
is not a Business Day shall be extended to the next succeeding Business Day
unless such Business Day falls in the next calendar month, in which case such
Interest Period shall end on the next preceding Business Day;

                  3.2.2 Amount of Borrowing Tranche.

                  each Borrowing Tranche of Revolving Credit Loans to which the
Euro-Rate Option applies shall be in integral multiples of $5,000,000 and not
less than $10,000,000;

                  3.2.3 Termination Before Applicable Expiration Date.

                  the Borrower shall not select, convert to or renew an Interest
Period for any portion of the Loans that would end, in the case of Revolving
Credit Loans, after the Expiration Date; and

                  3.2.4 Renewals.

                  in the case of the renewal of a Euro-Rate Option at the end of
an Interest Period, the first day of the new Interest Period shall be the last
day of the preceding Interest Period, without duplication in payment of interest
for such day.

            3.3 Interest After Default.

            To the extent permitted by Law, upon the occurrence of an Event of
Default and until such time such Event of Default shall have been cured or
waived:

                                     - 50 -
<PAGE>

                  3.3.1 Letter of Credit Fees, Interest Rate.

                  the Letter of Credit Fees and the rate of interest for each
Loan otherwise applicable pursuant to Section 2.9.2 [Letter of Credit Fees] or
Section 3.1 [Interest Rate Options], respectively, shall be increased by 2.0%
per annum; and

                  3.3.2 Other Obligations.

                  each other Obligation hereunder if not paid when due shall
bear interest at a rate per annum equal to the sum of the rate of interest
applicable under the Base Rate Option plus an additional 2.0% per annum from the
time such Obligation becomes due and payable until it is paid in full.

                  3.3.3 Acknowledgment.

                  The Borrower acknowledges that the increase in rates referred
to in this Section 3.3 reflects, among other things, the fact that such Loans or
other amounts have become a substantially greater risk given their default
status and that the Banks are entitled to additional compensation for such risk;
and all such interest shall be payable by Borrower upon demand by Administrative
Agent. Upon the occurrence of an Event of Default, no Loan may be made,
converted to or renewed under the Euro-Rate Option.

            3.4 Euro-Rate Unascertainable; Illegality; Increased Costs; Deposits
                Not Available.

                  3.4.1 Unascertainable.

                  If, on any date on which a Euro-Rate would otherwise be
determined with respect to Committed Loans, the Administrative Agent shall have
determined that:

                        (i) adequate and reasonable means do not exist for
ascertaining such Euro-Rate, or

                        (ii) a contingency has occurred which materially and
adversely affects the London interbank eurodollar market relating to the
Euro-Rate,

then the Administrative Agent shall have the rights specified in Section 3.4.3.

                  3.4.2 Illegality; Increased Costs; Deposits Not Available.

                  If at any time any Lender shall have determined that:

                        (i) the making, maintenance or funding of any Loan to
which a Euro-Rate Option applies has been made impracticable or unlawful by
compliance by such Lender in good faith with any Law or any interpretation or
application thereof by any Official Body or with any request or directive of any
such Official Body (whether or not having the force of Law), or

                                     - 51 -
<PAGE>

                        (ii) such Euro-Rate Option will not adequately and
fairly reflect the cost to such Lender of the establishment or maintenance of
any such Loan, or

                        (iii) after making all reasonable efforts, deposits of
the relevant amount in Dollars for the relevant Interest Period for a Loan to
which a Euro-Rate Option applies are not available to such Lender with respect
to such Loan, in the London interbank market,

then the Administrative Agent and the Lenders shall have the rights specified in
Section 3.4.3.

                  3.4.3 Administrative Agent's and Lender's Rights.

                  In the case of any event specified in Section 3.4.1 above, the
Administrative Agent shall promptly so notify the Lenders and the Borrower
thereof, and in the case of an event specified in Section 3.4.2 above, such
Lender shall promptly so notify the Administrative Agent and endorse a
certificate to such notice as to the specific circumstances of such notice, and
the Administrative Agent shall promptly send copies of such notice and
certificate to the other Lenders and the Borrower. Upon such date as shall be
specified in such notice (which shall not be earlier than the date such notice
is given), the obligation of (A) the Lenders, in the case of such notice given
by the Administrative Agent, or (B) such Lender, in the case of such notice
given by such Lender, to allow the Borrower to select, convert to or renew a
Euro-Rate Option shall be suspended until the Administrative Agent shall have
later notified the Borrower, or such Lender shall have later notified the
Administrative Agent, of the Administrative Agent's or such Lender's, as the
case may be, determination that the circumstances giving rise to such previous
determination no longer exist. If at any time the Administrative Agent makes a
determination under Section 3.4.1 and the Borrower has previously notified the
Administrative Agent of its selection of, conversion to or renewal of a
Euro-Rate Option and such Interest Rate Option has not yet gone into effect,
such notification shall be deemed to provide for the selection of, conversion to
or renewal of the Base Rate Option otherwise available with respect to such
Revolving Credit Loans if the Borrower has requested the Euro-Rate Option with
respect to such Revolving Credit Loans. If any Lender notifies the
Administrative Agent of a determination under Section 3.4.2, the Borrower shall,
subject to the Borrower's indemnification Obligations under Section 4.5.2
[Indemnity], as to any Loan of the Lender to which a Euro-Rate Option applies,
on the date specified in such notice either convert such Loan to the Base Rate
Option otherwise available with respect to such Loan or prepay such Loan in
accordance with Section 4.4.1 [Voluntary Prepayments]. Absent due notice from
the Borrower of conversion or prepayment, such Loan shall automatically be
converted to the Base Rate Option otherwise available with respect to such Loan
upon such specified date.

            3.5 Selection of Interest Rate Options.

            If the Borrower fails to select a new Interest Period to apply to
any Borrowing Tranche of Revolving Credit Loans under the Euro-Rate Option at
the expiration of an existing Interest Period applicable to such Borrowing
Tranche in accordance with the provisions of Section 3.2 [Interest Periods], the
Borrower shall be deemed to have converted such Borrowing

                                     - 52 -
<PAGE>

Tranche to the Base Rate Option in the case of Revolving Credit Loans commencing
upon the last day of the existing Interest Period.

                        4. PAYMENTS

            4.1 Payments.

            All payments and prepayments to be made in respect of principal,
interest, Commitment Fees, Letter of Credit Fees, Administrative Agent's Fee or
other fees or amounts due from the Borrower hereunder shall be payable prior to
11:00 a.m., Pittsburgh time, on the date when due without presentment, demand,
protest or notice of any kind, all of which are hereby expressly waived by the
Borrower, and without set-off, counterclaim or other deduction of any nature,
and an action therefor shall immediately accrue. Such payments shall be made to
the Administrative Agent at the Principal Office for the account of PNC Bank
with respect to the Swing Loans and for the ratable accounts of the Banks with
respect to the Revolving Credit Loans, in U.S. Dollars and in immediately
available funds, and the Administrative Agent shall promptly distribute such
amounts to the applicable Lenders in immediately available funds, provided that
in the event payments are received by 11:00 a.m., Pittsburgh time, by the
Administrative Agent with respect to the Loans and such payments are not
distributed to the Lenders (or applicable Lender, as the case may be) on the
same day received by the Administrative Agent, the Administrative Agent shall
pay the Lenders (or applicable Lender, as the case may be) the Federal Funds
Effective Rate with respect to the amount of such payments for each day held by
the Administrative Agent and not distributed to the Lenders (or applicable
Lender, as the case may be). The Administrative Agent's and each Lender's
statement of account, ledger or other relevant record shall, in the absence of
manifest error, be conclusive as the statement of the amount of principal of and
interest on the Loans and other amounts owing under this Agreement and shall be
deemed an "account stated." The principal amount of the Revolving Credit Loans,
together with accrued interest, fees and all other Obligations payable thereon
shall be due and payable on the Expiration Date.

            4.2 Pro Rata Treatment of Banks.

            Each borrowing of Revolving Credit Loans shall be allocated to each
Bank according to its Revolving Credit Ratable Share, and each selection of,
conversion to or renewal of any Interest Rate Option applicable to Revolving
Credit Loans and each payment or prepayment by the Borrower with respect to
principal or interest on the Revolving Credit Loans or Commitment Fees, Letter
of Credit Fees, or other fees (except for the Administrative Agent's Fee) or
amounts due from the Borrower hereunder to the Banks with respect to the
Revolving Credit Loans, shall (except as provided in Section 3.4.3
[Administrative Agent's and Lender's Rights] in the case of an event specified
in Sections 3.4 [Euro-Rate Unascertainable, etc.], 4.4.2 [Replacement of a
Lender] or 4.5 [Additional Compensation in Certain Circumstances]) be made in
proportion to the applicable Revolving Credit Loans outstanding from each Bank
and, if no such Loans are then outstanding, in proportion, as applicable, to the
Revolving Credit Ratable Share of each Bank. Notwithstanding any of the
foregoing, each borrowing or payment or prepayment by the Borrower of principal,
interest or other amounts from the Borrower with respect to Swing Loans shall be
made by or to PNC Bank according to Section 2.

<PAGE>

            4.3 Interest Payment Dates.

            Interest on Swing Loans or Revolving Credit Loans to which the Base
Rate Option applies shall be due and payable in arrears on the first Business
Day of each July, October, January and April after the date hereof and on the
Expiration Date or upon acceleration of the Loans. Interest on Committed Loans
(other than Swing Loans) to which the Euro-Rate Option applies shall be due and
payable on the last day of each Interest Period for those Loans and, if such
Interest Period is longer than three (3) Months, also on the date that is three
(3) Months after the commencement of such Interest Period (and if applicable,
the date that is six (6) Months after the commencement of such Interest Period)
of such Interest Period. Interest on the principal amount of each Loan or other
monetary Obligation shall be due and payable on demand after such principal
amount or other monetary Obligation becomes due and payable (whether on the
stated maturity date, upon acceleration or otherwise).

            4.4 Prepayments.

                  4.4.1 Voluntary Prepayments.

                  The Borrower shall have the right at its option from time to
time to prepay the Committed Loans in whole or part without premium or penalty
(except as provided in Section 4.4.2 below or in Section 4.5 [Additional
Compensation in Certain Circumstances]):

                        (i) at any time with respect to any Committed Loan to
which the Base Rate Option applies,

                        (ii) on the last day of the applicable Interest Period
with respect to Committed Loans to which a Euro-Rate Option applies,

                        (iii) on the date specified in a notice by any Lender
pursuant to Section 3.4 [Euro-Rate Unascertainable, etc.] with respect to any
Committed Loan to which a Euro-Rate Option applies.

Whenever the Borrower desires to prepay any part of the Committed Loans, it
shall provide a prepayment notice to the Administrative Agent by 1:00 p.m.,
Pittsburgh time, at least one (1) Business Day prior to the date of prepayment
of the Committed Loans or no later than 1:00 p.m., Pittsburgh time, on the date
of prepayment of Swing Loans setting forth the following information:

                     (x) the date, which shall be a Business Day, on which
the proposed prepayment is to be made;

                     (y) the application of the prepayment among the Swing
Loans and the Revolving Credit Loans; and

                     (z) the total principal amount of such prepayment, which
shall not be less than $10,000,000 for any Revolving Credit Loan, and in
increments of

                                     - 54 -
<PAGE>

$1,000,000 above $10,000,000, and not less than $1,000,000 for Swing Loans, and
in increments of $100,000 above $1,000,000.

All prepayment notices shall be irrevocable. The principal amount of the
Committed Loans for which a prepayment notice is given, together with interest
on such principal amount (except with respect to interest on Revolving Credit
Loans to which the Base Rate Option applies which shall be paid in accordance
with this Agreement on the next due date for the payment thereof), shall be due
and payable on the date specified in such prepayment notice as the date on which
the proposed prepayment is to be made. Except as provided in Section 3.4.3
[Administrative Agent's and Lender's Rights], if the Borrower prepays a
Committed Loan but fails to specify the applicable Borrowing Tranche which the
Borrower is prepaying, the prepayment shall be applied (i) first to Swing Loans,
then (ii) second to Revolving Credit Loans to which the Base Rate Option
applies, and then (iii) finally to Revolving Credit Loans to which the Euro-Rate
Option applies. Any prepayment hereunder shall be subject to the Borrower's
Obligation to indemnify the Banks under Section 4.5.2 [Indemnity].

                  4.4.2 Replacement of a Lender.

                  In the event any Lender (i) gives notice under Section 3.4
[Euro-Rate Unascertainable, etc.] or Section 4.5.1 [Increased Costs, etc.], (ii)
does not fund Revolving Credit Loans because the making of such Loans would
contravene any Law applicable to such Lender, or (iii) becomes subject to the
control of an Official Body (other than normal and customary supervision), then
the Borrower shall have the right at its option, with the consent of the
Administrative Agent, which shall not be unreasonably withheld (except that
during any period when an Event of Default exists and is continuing, the
Administrative Agent may withhold such consent in its sole discretion), to
prepay the Loans of such Lender in whole, together with all interest and fees
accrued thereon and all other amounts due and payable to such Lender under the
Loan Documents, and terminate such Lender's Commitment within ninety (90) days
after (x) receipt of such Lender's notice under Section 3.4 [Euro-Rate
Unascertainable, etc.] or 4.5.1 [Increased Costs, Etc.], (y) the date such
Lender has failed to fund Revolving Credit Loans because the making of such
Loans would contravene Law applicable to such Lender, or (z) the date such
Lender became subject to the control of an Official Body, as applicable;
provided that the Borrower shall also pay to such Lender at the time of such
prepayment any amounts required under Section 4.5 [Additional Compensation in
Certain Circumstances] (except that the Borrower shall not be required to
indemnify such Lender for liabilities, losses or expenses under Section 4.5.2(i)
sustained by such Lender as a consequence of the prepayment of the Loans of such
Lender in accordance with this Section 4.4.2 on a day other than the last day of
an Interest Period with respect to Loans to which a Euro-Rate Option applies if
the Loans of such Lender are being prepaid because such Lender has determined
that the making, maintenance or funding of such Loans by such Lender under the
Euro-Rate Option has been made unlawful or because such Lender has become
subject to the control of an Official Body) and any accrued interest due on such
amount and any related fees; provided, however, that the Commitment of such
Lender shall be provided by one or more of the remaining Lenders or a
replacement bank acceptable to the Agents and the Issuing Banks; provided,
further, that the remaining Lenders shall have no obligation hereunder to
increase their Commitments. Notwithstanding the foregoing, the Administrative
Agent may only be replaced subject to the requirements of Section 9.14

                                     - 55 -
<PAGE>

[Successor Agents] and an Issuing Bank may only be replaced if all Letters of
Credit issued by such Issuing Bank have expired or been terminated or replaced.

                  4.4.3 Change of Lending Office.

                  Each Lender agrees that upon the occurrence of any event
giving rise to increased costs or other special payments under Section 3.4.2
[Illegality, etc.] or 4.5.1 [Increased Costs, etc.] with respect to such Lender,
it will if requested by the Borrower, use reasonable efforts (subject to overall
policy considerations of such Lender) to designate another lending office for
any Loans or Letters of Credit affected by such event, provided that such
designation is made on such terms that such Lender and its lending office suffer
no economic, legal or regulatory disadvantage on such Lender's good faith
determination, with the object of avoiding the consequence of the event giving
rise to the operation of such Section. Nothing in this Section 4.4.3 shall
affect or postpone any of the Obligations of the Borrower or any other Loan
Party or the rights of any Agent or any Lender provided in this Agreement.

                  4.4.4 Voluntary Reduction of Commitments.

                  The Borrower shall have the right, upon not less than five (5)
Business Days' written irrevocable notice to the Administrative Agent, to
terminate the Revolving Credit Commitments or, from time to time, to reduce the
amount of the Revolving Credit Commitments, which notice shall specify the date
and amount of any such reduction and otherwise be substantially in the form of
Exhibit 4.4.4 (a "Commitment Reduction Notice"). Any such reduction shall be in
a minimum amount equal to $10,000,000 or an integral multiple of $1,000,000 in
excess thereof, provided, that the Revolving Credit Commitments may not be
reduced below the sum of the aggregate principal amount of all Revolving
Facility Usage. Each reduction of Revolving Credit Commitments shall ratably
reduce the Revolving Credit Commitments of the Banks.

                  4.4.5 Mandatory Prepayment Upon Sale of Assets; Mandatory
                        Reduction of Revolving Credit Commitments.

                  Within five (5) Business Days of any sale of assets by any
member of the Arch Coal Group authorized by Section 7.2.4(vi) [Disposition of
Assets or Subsidiaries] and immediately upon the closing of any Permitted
Receivables Financing, the Revolving Credit Commitments shall automatically and
permanently be reduced in an amount equal to, in the case of an asset sale under
Section 7.2.4(vi), the Net Cash Proceeds of such sale of assets (as estimated in
good faith by the Borrower) or, in the case of a Permitted Receivables
Financing, 50% of the principal amount of such financing; provided, however,
that, in the case of a sale of assets authorized by Section 7.2.4(vi), the
Revolving Credit Commitments shall not be required to be reduced below
$150,000,000. On the date of any reduction of the Revolving Credit Commitments
pursuant to this Section 4.4.5, the Borrower shall make a mandatory prepayment
of so much of the Revolving Credit Loans as shall be necessary in order that the
Revolving Facility Usage will not exceed the Revolving Credit Commitments after
giving effect to such reduction. Any prepayment hereunder shall be subject to
the Borrower's Obligation to the Banks under Section 4.5.2 [Indemnity]. If the
Debt Rating applicable to the Borrower is BBB- or better

                                     - 56 -
<PAGE>

by Standard & Poor's or Baa3 or better by Moody's, then at any time when either
such Debt Rating is in effect, if any member of the Arch Coal Group sells assets
in accordance with Section 7.2.4(vi), no reduction of the Revolving Credit
Commitments pursuant to this Section 4.4.5 will be required to be made. No
reduction of the Revolving Credit Commitments will be required under this
Section 4.4.5 with respect to proceeds of the MLP Transaction.

            4.5 Additional Compensation in Certain Circumstances.

                  4.5.1 Increased Costs or Reduced Return Resulting From Taxes,
                        Reserves, Capital Adequacy Requirements, Expenses, Etc.

                  If any Law, guideline or interpretation or any change in any
Law, guideline or interpretation or application thereof by any Official Body
charged with the interpretation or administration thereof or compliance with any
request or directive (whether or not having the force of Law) of any central
bank or other Official Body:

                        (i) subjects any Lender to any tax or changes the basis
of taxation with respect to this Agreement, the Committed Loans or payments by
the Borrower of principal, interest, Commitment Fees, or other amounts due from
the Borrower hereunder (except for taxes on the overall net income of such
Lender),

                        (ii) imposes, modifies or deems applicable any reserve,
special deposit or similar requirement against credits or commitments to extend
credit extended by, or assets (funded or contingent) of, deposits with or for
the account of, or other acquisitions of funds by, any Lender, or

                        (iii) imposes, modifies or deems applicable any capital
adequacy or similar requirement (A) against assets (funded or contingent) of, or
letters of credit, other credits or commitments to extend credit extended by,
any Lender, or (B) otherwise applicable to the obligations of any Lender under
this Agreement,

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Lender with respect to this Agreement, or the making, maintenance or funding of
any part of the Committed Loans (or, in the case of any capital adequacy or
similar requirement, to have the effect of reducing the rate of return on any
Lender's capital, taking into consideration such Lender's customary policies
with respect to capital adequacy) by an amount which such Lender in its sole
discretion deems to be material, such Lender shall from time to time notify the
Borrower and the Administrative Agent of the amount determined in good faith
(using any averaging and attribution methods employed in good faith) by such
Lender to be necessary to compensate such Lender for such increase in cost,
reduction of income, additional expense or reduced rate of return. Such notice
shall set forth in reasonable detail the basis for such determination. Such
amount shall be due and payable by the Borrower to such Lender ten (10) Business
Days after such notice is given.

                  4.5.2 Indemnity.

                  In addition to the compensation required by Section 4.5.1
[Increased Costs, etc.], the Borrower shall indemnify each Lender against all
liabilities, losses or expenses (including loss of margin, any loss or expense
incurred in liquidating or employing deposits from third parties and any loss or
expense incurred in connection with funds acquired by a Lender to fund or
maintain Loans subject to a Euro-Rate Option) which such Lender sustains or
incurs as a consequence of any

                        (i) payment, prepayment, conversion or renewal of any
Loan to which a Euro-Rate Option applies on a day other than the last day of the
corresponding Interest Period (whether or not such payment or prepayment is
mandatory, voluntary or automatic and whether or not such payment or prepayment
is then due);

                        (ii) attempt by the Borrower to revoke (expressly, by
later inconsistent notices or otherwise) in whole or part any Committed Loan
Requests under Section 2.4.1 [Committed Loan Requests], Section 2.4.2 [Swing
Loan Requests], or Section 3.2 [Interest Periods] or notice relating to
prepayments under Section 4.4.1 [Voluntary Prepayments]; or

                        (iii) default by the Borrower in the performance or
observance of any covenant or condition contained in this Agreement or any other
Loan Document, including any failure of the Borrower to pay when due (by
acceleration or otherwise) any principal of or interest on the Committed Loans,
Commitment Fees or any other amount due hereunder.

If any Lender sustains or incurs any such loss or expense, it shall from time to
time notify the Borrower of the amount determined in good faith by such Lender
(which determination may include such assumptions, allocations of costs and
expenses and averaging or attribution methods as such Lender shall deem
reasonable) to be necessary to indemnify such Lender for such loss or expense.
Such notice shall set forth in reasonable detail the basis for such
determination. Such amount shall be due and payable by the Borrower to such
Lender ten (10) Business Days after such notice is given.

            4.6 Notes.

            Upon the request of any Bank, the Revolving Credit Loans made by
such Bank may be evidenced by a Revolving Credit Note in the form of Exhibit
1.1(R).

            4.7 Settlement Date Procedures.

            In order to minimize the transfer of funds between the Banks and the
Administrative Agent, the Borrower may borrow, repay and reborrow Swing Loans
and PNC Bank may make Swing Loans as provided in Section 2.5 hereof during the
period between Settlement Dates. Not later than 11:00 a.m., on each Settlement
Date, the Administrative Agent shall notify each Bank of its Revolving Credit
Ratable Share of the total of the Revolving Credit Loans and the Swing Loans
(each a "Required Share"). Prior to 2:00 p.m., Pittsburgh time, on

                                     - 58 -
<PAGE>

such Settlement Date, each Bank shall pay to the Administrative Agent the amount
equal to the difference between its Required Share and its Revolving Credit
Loans, and the Administrative Agent shall pay to each Bank its Revolving Credit
Ratable Share of all payments made by the Borrower to the Administrative Agent
with respect to the Revolving Credit Loans. The Administrative Agent shall also
effect settlement in accordance with the foregoing sentence on the proposed
Borrowing Dates for Revolving Credit Loans and may at its option effect
settlement on any other Business Day. These settlement procedures are
established solely as a matter of administrative convenience, and nothing
contained in this Section 4.7 shall relieve the Banks of their obligations to
fund Revolving Credit Loans on dates other than a Settlement Date pursuant to
Sections 2.1.1 and 2.2. The Administrative Agent may at any time for any reason
whatsoever require each Bank to pay immediately to the Administrative Agent such
Bank's Revolving Credit Ratable Share of the outstanding Revolving Credit Loans,
and each Bank may at any time require the Administrative Agent to pay
immediately to such Bank its Revolving Credit Ratable Share of all payments made
by the Borrower to the Administrative Agent with respect to the Revolving Credit
Loans.

            4.8 Taxes.

                  4.8.1 No Deductions.

                  All payments made by the Borrower hereunder shall be made free
and clear of and without deduction for any present or future taxes, levies,
imposts, deductions, charges, or withholdings, and all liabilities with respect
thereto, excluding taxes imposed on the net income of the Lenders and all income
and franchise taxes of the United States applicable to the Lenders (all such
non-excluded taxes, levies, imposts deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable under
the Credit Agreement, (i) the sum payable shall be increased as may be necessary
so that after making all required deductions (including deductions applicable to
additional sums payable under this subsection) the Administrative Agent receives
an amount equal to the sum it would have received had no such deductions been
made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall
timely pay the full amount deducted to the relevant tax authority or other
authority in accordance with applicable law.

                  4.8.2 Stamp Taxes.

                  In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges, or
similar levies which arise from any payment made hereunder or from the
execution, delivery, or registration, or otherwise with respect to, the Credit
Agreement (hereinafter referred to as "Other Taxes").

                  4.8.3 Indemnification for Taxes Paid by Lenders.

                  The Borrower shall indemnify the Lenders for the full amount
of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this subsection) paid by
such Lender and any liability

                                     - 59 -
<PAGE>

(including penalties, interest, and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted. This indemnification shall be made within 30 days from the date such
Lender makes written demand therefor.

                  4.8.4 Certificate.

                  Within 30 days after the date of any payment of any Taxes by
the Borrower, the Borrower shall furnish to the Administrative Agent for the
benefit of the Lenders the original or a certified copy of a receipt evidencing
payment thereof. If no Taxes are payable in respect of any payment by the
Borrower, the Borrower shall, if so requested by any Lender, provide a
certificate of an officer of the Borrower to that effect.

                  4.8.5 Survival.

                  Without prejudice to the survival of any other agreement of
the Borrower hereunder, the agreements and obligations of the Borrower contained
in subsections 4.8.1 through 4.8.4 shall survive the payment in full of
principal and interest under any promissory note made by Borrower to any Lender
under the Credit Agreement.

                  4.8.6 Refund and Contest.

                  If the Borrower determines in good faith that a reasonable
basis exists for contesting any Taxes or Other Taxes with respect to which the
Borrower was required to take the actions specified in the second sentence of
subsection 4.8.1, the relevant Lender (to the extent such Lender reasonably
determines in good faith that it will not suffer any adverse effect as a result
thereof) shall cooperate with the Borrower in challenging the imposition of such
Taxes or Other Taxes at the Borrower's expense if so requested by the Borrower
in writing. If such Lender receives a refund of Taxes or Other Taxes for which
the payment has been made by the Borrower pursuant to this Agreement, which
refund in the good faith judgment of such Lender is attributable to the
Borrower, then such Lender shall reimburse the Borrower for such amount as such
Lender determines to be the proportion of the refund as will leave it, after
such reimbursement, in no better or worse position than it would have been in if
the payment had not been required. No Lender nor any Agent shall be obliged to
disclose information regarding its tax affairs or computations to Borrower in
connection with this Section 4.8.6 or any other provision of Section 4.8.

                  5. REPRESENTATIONS AND WARRANTIES

            5.1 Representations and Warranties.

            The Borrower represents and warrants to the Agents and each of the
Lenders as follows:

                  Each Loan Party and each Subsidiary of each Loan Party is a
corporation, partnership or limited liability company duly organized, validly
existing and in good standing

                                     - 60 -
<PAGE>

under the laws of its jurisdiction of organization. Each Loan Party and each
Subsidiary of each Loan Party has the lawful power to own or lease its
properties and to engage in the business it presently conducts or proposes to
conduct. Each Loan Party and each Subsidiary of each Loan Party is duly licensed
or qualified and in good standing in each jurisdiction where the property owned
or leased by it or the nature of the business transacted by it or both makes
such licensing or qualification necessary and where the failure to so qualify
could reasonably be expected to result in a Material Adverse Change.

                  5.1.2 Shares of Borrower; Subsidiaries; and Subsidiary Shares.

                  Schedule 5.1.2 states the name of each of the Borrower's
Subsidiaries, its jurisdiction of incorporation, its authorized capital stock,
the issued and outstanding shares (referred to herein as the "Subsidiary
Shares") and the owners thereof if it is a corporation, its outstanding
partnership interests (the "Partnership Interests") if it is a partnership and
its outstanding limited liability company interests, interests assigned to
managers thereof and the voting rights associated therewith (the "LLC
Interests") if it is a limited liability company. Schedule 5.1.2 also sets forth
the jurisdiction of incorporation of the Borrower, its authorized capital stock
(the "Borrower Shares"), the voting rights associated therewith, and whether
such Subsidiary is a Significant Subsidiary, Inactive Subsidiary or a Special
Subsidiary. The Borrower and each Subsidiary of the Borrower has good and
marketable title to all of the Subsidiary Shares, Partnership Interests and LLC
Interests it purports to own, free and clear in each case of any Lien. All
Borrower Shares, Subsidiary Shares, Partnership Interests and LLC Interests have
been validly issued, and all Borrower Shares and all Subsidiary Shares are fully
paid and nonassessable. All capital contributions and other consideration
required to be made or paid in connection with the issuance of the Partnership
Interests and LLC Interests have been made or paid, as the case may be. There
are no options, warrants or other rights outstanding to purchase any such
Borrower Shares, Subsidiary Shares, Partnership Interests or LLC Interests
except as indicated on Schedule 5.1.2.

                  5.1.3 Power and Authority.

                  Each Loan Party has full power to enter into, execute, deliver
and carry out this Agreement and the other Loan Documents to which it is a
party, to incur the Indebtedness contemplated by the Loan Documents and to
perform its Obligations under the Loan Documents to which it is a party, and all
such actions have been duly authorized by all necessary proceedings on its part.
The Borrower and each Subsidiary of the Borrower party to the Acquisition
Documents has full power to enter into, execute, deliver and perform the
Acquisition Documents to which it is a party, and all such actions have been
duly authorized by all necessary proceedings on its part. The Borrower and each
Subsidiary of the Borrower party to the Vulcan Acquisition Documents has full
power to enter into, execute, deliver and perform the Vulcan Acquisition
Documents to which it is a party, and all such actions have been duly authorized
by all necessary proceedings on its part.

                  This Agreement has been duly and validly executed and
delivered by each Loan Party, and each other Loan Document which any Loan Party
is required to execute and deliver on or after the date hereof will have been
duly executed and delivered by such Loan Party on the required date of delivery
of such Loan Document. This Agreement and each other Loan Document constitutes,
or will constitute, legal, valid and binding obligations of each Loan Party
which is or will be a party thereto on and after its date of delivery thereof,
enforceable against such Loan Party in accordance with its terms, except to the
extent that enforceability of any of such Loan Document may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforceability of creditors' rights generally or limiting the
right of specific performance. The Acquisition Documents have been duly and
validly executed and delivered by the Borrower and each of its Subsidiaries
party thereto. The Acquisition Documents constitute the legal, valid and binding
obligation of the Borrower and each of its Subsidiaries party thereto,
enforceable against each such Person in accordance with the terms thereof,
except to the extent that enforceability of the Acquisition Documents may be
limited by bankruptcy, insolvency, reorganization, moratorium or other similar
law, affecting the enforceability of creditors' rights generally or limiting the
right of specific performance. A complete copy of the Acquisition Documents has
been delivered to the Administrative Agent. The Vulcan Acquisition Documents
have been duly and validly executed and delivered by the Borrower and each of
its Subsidiaries party thereto. The Vulcan Acquisition Documents constitute the
legal, valid and binding obligation of the Borrower and each of its Subsidiaries
party thereto, enforceable against each such Person in accordance with the terms
thereof, except to the extent that enforceability of the Vulcan Acquisition
Documents may be limited by bankruptcy, insolvency, reorganization, moratorium
or other similar law, affecting the enforceability of creditors' rights
generally or limiting the right of specific performance. A complete copy of the
Vulcan Acquisition Documents has been delivered to the Administrative Agent.

                  5.1.5 No Conflict.

                  Neither the execution and delivery of the Loan Documents or
the Vulcan Acquisition Documents by any Loan Party, nor the consummation of the
transactions herein or therein contemplated or compliance with the terms and
provisions hereof or thereof by any of them will conflict with, constitute a
default under or result in any breach of (i) the terms and conditions of the
certificate of incorporation, bylaws, certificate of limited partnership,
partnership agreement, certificate of formation, limited liability company
agreement or other organizational documents of any Loan Party or any Subsidiary
of any Loan Party or (ii) any Law or any material agreement or instrument or
order, writ, judgment, injunction or decree to which any Loan Party or any
Subsidiary of any Loan Party is a party or by which any of the foregoing Persons
is bound or to which any of the foregoing Persons is subject, or result in the
creation or enforcement of any Lien, charge or encumbrance whatsoever upon any
property (now or hereafter acquired) of any Loan Party or any Subsidiary of any
Loan Party (other than Liens granted under the Loan Documents).

                  5.1.6 Litigation.

                  Except as set forth on Schedule 5.1.6, there are no actions,
suits, proceedings or investigations pending or, to the knowledge of any Loan
Party, threatened against such Loan Party or any Subsidiary of such Loan Party
at law or equity before any Official Body which individually or in the aggregate
could reasonably be expected to result in a Material Adverse Change. None of the
Loan Parties or any Subsidiary of any Loan Party is in violation of any order,
writ, injunction or any decree of any Official Body which could reasonably be
expected to result in a Material Adverse Change.

                  5.1.7 Financial Statements.

                        (i) Historical Statements.

                     The Borrower has delivered to the Administrative Agent
copies of its audited consolidated year-end financial statements for and as of
the end of the fiscal year ended December 31, 2002 (the "Historical
Statements"). The Historical Statements were compiled from the books and records
maintained by the Borrower's management, are correct and complete and fairly
represent the consolidated financial condition of the Borrower and its
Subsidiaries as of their dates and the results of operations for the fiscal
periods then ended and have been prepared in accordance with GAAP consistently
applied.

                        (ii) Accuracy of Financial Statements.

                     Neither the Borrower nor any Subsidiary of the Borrower has
on the Second Restatement Effective Date any liabilities, contingent or
otherwise, or forward or long-term commitments that are not disclosed in the
Historical Statements or in the notes thereto, and except as disclosed therein
there are no unrealized or anticipated losses from any commitments of the
Borrower or any Subsidiary of the Borrower which could reasonably be expected to
result in a Material Adverse Change. Since December 31, 2002, no Material
Adverse Change has occurred, except as set forth on Schedule 5.1.7.

                        (iii) Financial Projections. The Borrower has delivered
to the Agents financial projections of the Borrower and its Subsidiaries, on a
consolidated and consolidating basis, for the period January 1, 2003 through and
including December 31, 2006 derived from various assumptions of the Borrower's
management (the "Financial Projections"). On the Second Restatement Effective
Date, the Financial Projections represent a reasonable range of possible results
in light of the history of the business, present and foreseeable conditions and
the intentions of the Borrower's management. The Financial Projections
accurately reflect, in all material respects on a consolidated basis, the
liabilities of the Borrower and its Subsidiaries upon consummation of the
transactions contemplated hereby as of the Second Restatement Effective Date.

                  5.1.8 Use of Proceeds; Margin Stock.

                     5.1.8.1 General.

<PAGE>

                     The Loan Parties shall use the proceeds of the Loans in
accordance with Sections 2.7 and 7.1.9.

                     5.1.8.2 Margin Stock.

                     None of the Loan Parties nor any Subsidiary of any Loan
Party engages or intends to engage principally, or as one of its important
activities, in the business of extending credit for the purpose, immediately,
incidentally or ultimately, of purchasing or carrying margin stock (within the
meaning of Regulation U). No part of the proceeds of any Loan has been or will
be used, immediately, incidentally or ultimately, to purchase or carry any
margin stock or to extend credit to others for the purpose of purchasing or
carrying any margin stock or to refund Indebtedness originally incurred for such
purpose, or for any purpose which entails a violation of or which is
inconsistent with the provisions of the regulations of the Board of Governors of
the Federal Reserve System. None of the Loan Parties nor any Subsidiary of any
Loan Party holds or intends to hold margin stock in such amounts that more than
25% of the reasonable value of the assets of any Loan Party or Subsidiary of any
Loan Party are or will be represented by margin stock.

                  5.1.9 Full Disclosure.

                  Neither this Agreement nor any other Loan Document, nor the
Acquisition Documents, nor the Vulcan Acquisition Documents, nor any
certificate, statement, agreement or other documents furnished to the
Administrative Agent or any Lender in connection herewith, with the Acquisition
Documents or with the Vulcan Acquisition Documents, contains with respect to the
Borrower and its Subsidiaries any untrue statement of a material fact or omits
to state a material fact necessary in order to make the statements contained
herein and therein, in light of the circumstances under which they were made,
not misleading. There is no fact known to any Loan Party which materially
adversely affects the business, financial condition or results of operations of
the Borrower and its Subsidiaries taken as a whole which has not been set forth
in this Agreement or in the certificates, statements, agreements or other
documents furnished in writing to the Administrative Agent and the Lenders prior
to or at the date hereof in connection with the transactions contemplated
hereby.

                  5.1.10 Taxes.

                  All federal, state, local and other tax returns required to
have been filed with respect to each Loan Party and each Subsidiary of each Loan
Party have been filed, and payment or adequate provision has been made for the
payment of all taxes, fees, assessments and other governmental charges which
have or may become due pursuant to said returns or to assessments received,
except to the extent that such taxes, fees, assessments and other charges are
being contested in good faith by appropriate proceedings diligently conducted
and for which such reserves or other appropriate provisions, if any, as shall be
required by GAAP shall have been made. There are no agreements or waivers
extending the statutory period of limitations applicable to any federal income
tax return of any Loan Party or Subsidiary of any Loan Party for any period.

                  5.1.11 Consents and Approvals.

                     No consent, approval, exemption, order or authorization of,
or a registration or filing with, any Official Body or any other Person is
required by any Law or any agreement in connection with the execution, delivery
and carrying out of this Agreement and the other Loan Documents by any Loan
Party, except as listed on Schedule 5.1.11, all of which shall have been
obtained or made on or prior to the Second Restatement Effective Date except as
otherwise indicated on Schedule 5.1.11.

                            Material Contracts.

                     No event has occurred and is continuing and no condition
exists or will exist after giving effect to the borrowings or other extensions
of credit to be made on the Second Restatement Effective Date under or pursuant
to the Loan Documents which constitutes an Event of Default or Potential
Default. None of the Loan Parties or any Subsidiary of any Loan Party is in
violation of (i) any term of its certificate of incorporation, bylaws,
certificate of limited partnership, partnership agreement, certificate of
formation, limited liability company agreement or other organizational documents
or (ii) any material agreement or instrument to which it is a party or by which
it or any of its properties may be subject or bound where such violation could
reasonably be expected to result in a Material Adverse Change. All Material
Contracts described in the definition of "Material Contracts" to which any Loan
Party or any Subsidiary of any Loan Party is a party or by which any Loan Party
or Subsidiary of any Loan Party is bound are valid, binding and enforceable upon
such Loan Party or Subsidiary and to the best knowledge of the Borrower upon
each of the other parties thereto in accordance with their respective terms, and
there is no default by any Loan Party or any Subsidiary of any Loan Party under
any Material Contract nor, to the Loan Parties' knowledge, any default
thereunder with respect to parties thereto other than any Loan Party or
Subsidiary of a Loan Party except in each case to the extent the same could not
reasonably be expected to result in a Material Adverse Change. None of the Loan
Parties or their Subsidiaries is bound by any contractual obligation, or subject
to any restriction in any organization document, or any requirement of Law which
could reasonably be expected to result in a Material Adverse Change.

                  No notice has been given or claim made and no grounds exist to
cancel or avoid any insurance policies or bonds to which the Loan Parties are
subject, or to reduce the coverage provided thereby. Such policies and bonds
provide adequate coverage from reputable and financially sound insurers in
amounts sufficient to insure the assets and risks of each Loan Party and each
Subsidiary of each Loan Party in accordance with prudent business practice in
the industry of the Loan Parties and their Subsidiaries.

                  5.1.14 Compliance With Laws.

                  The Loan Parties and their Subsidiaries are in compliance in
all material respects with all applicable Laws (other than Environmental Laws

as such terms are defined in the Investment Company Act of 1940 and shall not

state statute or regulation limiting its ability to incur Indebtedness for
borrowed money.

to any Multiemployer Plan or Multiple Employer Plan, which could result in any
material liability of the Borrower or any other member of the ERISA Group. The
Borrower and all other members of the ERISA Group have made when due any and all
payments required to be made under any agreement relating to a Multiemployer

ERISA Group has incurred or reasonably expects to incur any material withdrawal
liability under ERISA to any Multiemployer Plan or Multiple Employer Plan.

Multiple Employer Plan is reasonably expected to be reorganized or terminated,
within the meaning of Title IV of ERISA.

                  Each Loan Party shall, and shall cause each of its

force and effect all patents, trademarks, service marks, trade names,

shall deliver to Lenders any certification or other evidence reasonably
requested from time to time by any Lender, confirming Borrower's compliance with

                  If an Event of Default specified under Sections 8.1.1 through
8.1.13 shall occur and be continuing, the Banks, the Issuing Banks and the
Administrative Agent shall be under no further obligation to make Revolving
Credit Loans or Swing Loans or issue Letters of Credit, as the case may be (and

declare the unpaid principal amount of the Revolving Credit Loans and Swing
Loans then outstanding and all interest accrued thereon, any unpaid fees and all
other Indebtedness of the Borrower to the Lenders hereunder and thereunder to be
forthwith due and payable, and the same shall thereupon become and be
immediately due and payable to the Administrative Agent for the benefit of each
Bank without presentment, demand, protest or any other notice of any kind, all
of which are hereby expressly waived, and (iii) require the Borrower to, and the
Borrower shall thereupon, deposit in a non-interest-bearing account with the
Administrative Agent, as cash collateral for its Obligations under the Loan
Documents, an amount equal to the maximum amount currently or at any time
thereafter available to be drawn on all outstanding Letters of Credit, and the
Borrower hereby pledges to the Administrative Agent and the Banks, and grants to
the Administrative Agent and the Banks a security interest in, all such cash as
security for such Obligations. Upon the curing of all existing Events of Default
to the satisfaction of the Required Banks, the Administrative Agent shall return
such cash collateral to the Borrower; and

                  8.2.2 Bankruptcy, Insolvency or Reorganization Proceedings.

expressly waived; and

                  8.2.3 Set-off.

                  If an Event of Default shall occur and be continuing, any
Lender to whom any Obligation is owed by any Loan Party hereunder or under any
other Loan Document or any participant of such Lender which has agreed in
writing to be bound by the provisions of Section 9.13 [Equalization of Lenders]
and any branch, Subsidiary or Affiliate of such Lender or participant anywhere
in the world shall have the right, in addition to all other rights and remedies
available to it, without notice to such Loan Party, to set-off against and apply
to the then unpaid balance of all the Loans and all other Obligations of the
Borrower and the other Loan Parties hereunder or under any other Loan Document
any debt owing to, and any other funds held in any manner for the account of,
the Borrower or such other Loan Party by such Lender or participant or by such
branch, Subsidiary or Affiliate, including all funds in all deposit accounts
(whether time or demand, general or special, provisionally credited or finally
credited, or otherwise) now or hereafter maintained by the Borrower or such
other Loan Party for its own account (but not including funds held in custodian
or trust accounts) with such Lender or participant or such branch, Subsidiary or
Affiliate. Such right shall exist whether or not any Lender or the
Administrative Agent shall have made any demand under this Agreement or any
other Loan Document, whether or not such debt owing to or funds held for the
account of the Borrower or such other Loan Party is or are matured or unmatured
and regardless of the existence or adequacy of any Guaranty or any other
security, right or remedy available to any Lender or the Administrative Agent;
and

                  8.2.4 Suits, Actions, Proceedings.

                  If an Event of Default shall occur and be continuing, and
whether or not the Administrative Agent shall have accelerated the maturity of
the Committed Loans pursuant to any of the foregoing provisions of this Section
8.2, the Agents or the Required Banks (or at the request of the Agents or the
Required Banks, any Bank, and any such Bank that has received such a request
shall thus be entitled to exercise the rights set forth in this Section ) if
owed any amount with respect to the Loans, may, to the extent permitted by Law,
proceed to protect and enforce its rights by suit in equity, action at law
and/or other appropriate proceeding, whether for the specific performance of any
covenant or agreement contained in this Agreement or the other Loan Documents,
including as permitted by applicable Law the obtaining of the ex parte
appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of any Agent or such Bank; and

                  8.2.5 Application of Proceeds.

                  From and after the date on which the Administrative Agent or
any Lender shall have taken any action pursuant to this Section 8.2 and until
all Obligations of the Loan Parties have been paid in full, subject to the
provisions of the Collateral Sharing Agreement, any

                                    - 102 -
<PAGE>

and all proceeds received by the Administrative Agent or any Lender from the
exercise of any remedy by the Administrative Agent or any Lender shall be
applied as follows:

                        (i) first, to reimburse the Administrative Agent and the
Lenders for out-of-pocket costs, expenses and disbursements, including
reasonable attorneys' and paralegals' fees and legal expenses, incurred by the
Administrative Agent or the Lenders in connection with collection of any
Obligations of any of the Loan Parties under any of the Loan Documents;

                        (ii) second, to the repayment of all Indebtedness then
due and unpaid of the Loan Parties to the Lenders incurred under this Agreement
or any of the other Loan Documents, whether of principal, interest, fees,
expenses or otherwise, in such manner as the Administrative Agent may determine
in its discretion; and

                        (iii) the balance, if any, as required by Law.

                  8.2.6 Other Rights and Remedies.

                  In addition to all of the rights and remedies contained in
this Agreement or in any of the other Loan Documents, the Administrative Agent
shall have all of the rights and remedies under applicable Law, all of which
rights and remedies shall be cumulative and non-exclusive, to the extent
permitted by Law. The Administrative Agent may, and upon the request of the
Required Banks shall, exercise all post-default rights granted to the
Administrative Agent and the Lenders under the Loan Documents or applicable Law.

                        9. THE AGENTS

            9.1 Appointment.

            Each Lender hereby designates, appoints and authorizes: (i) PNC Bank
to act as Administrative Agent for such Lender under this Agreement and the
other Loan Documents for such Lender under this Agreement and to execute and
deliver or accept on behalf of each of the Lenders the other Loan Documents, and
(ii) authorizes each of PNC Bank and JPMorgan Chase to act as Agent for such
Lender under this Agreement. Each Lender hereby irrevocably authorizes the
Administrative Agent to take such action on its behalf under the provisions of
this Agreement and the other Loan Documents and any other instruments and
agreements referred to herein, and to exercise such powers and to perform such
duties hereunder as are specifically delegated to or required of the Agents, the
Administrative Agent or any of them by the terms hereof, together with such
powers as are reasonably incidental thereto. PNC Bank agrees to act as the
Administrative Agent on behalf of the Lenders to the extent provided in this
Agreement, and each of PNC Bank and JPMorgan Chase agrees to act as Agent on
behalf of the Banks to the extent provided in this Agreement.

            9.2 Delegation of Duties.

            The Agents and the Administrative Agent may perform any of their
respective duties hereunder by or through agents or employees (provided such
delegation does not constitute

                                    - 103 -
<PAGE>

a relinquishment of their respective duties as Agents or the Administrative
Agent, as the case may be) and, subject to Sections 9.5 [Reimbursement and
Indemnification of Agents by the Borrower] and 9.6 [Exculpatory Provisions;
Limitation of Liability], shall be entitled to engage and pay for the advice or
services of any attorneys, accountants or other experts concerning all matters
pertaining to its duties hereunder and to rely upon any advice so obtained. It
is acknowledged and agreed that each of Citibank, Credit Lyonnais, and U.S. Bank
has received the title of Documentation Agent under this Agreement, however,
such designation is solely to give each of Citibank, Credit Lyonnais, and U.S.
Bank such title and each of Citibank, Credit Lyonnais, and U.S. Bank has no
duties, responsibilities, functions, obligations or liabilities implied or
otherwise under the Loan Documents solely as a result of being so designated as
Documentation Agent.

            9.3 Nature of Duties; Independent Credit Investigation.

            Neither the Agents nor the Administrative Agent shall have any
duties or responsibilities except those expressly set forth in this Agreement
and no implied covenants, functions, responsibilities, duties, obligations, or
liabilities shall be read into this Agreement or otherwise exist. The duties of
the Administrative Agent and of the Agents shall be mechanical and
administrative in nature; neither the Administrative Agent nor the Agents shall
have by reason of this Agreement a fiduciary or trust relationship in respect of
any Lender; and nothing in this Agreement, expressed or implied, is intended to
or shall be so construed as to impose upon the Administrative Agent or any Agent
any obligations in respect of this Agreement except as expressly set forth
herein. Without limiting the generality of the foregoing, the use of the term
"Agents" in this Agreement with reference to the Agents or Administrative Agent,
as the case may be, is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable Law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties. Each Lender expressly acknowledges (i) that neither the
Administrative Agent nor any Agent has made any representations or warranties to
it and that no act by the Administrative Agent or any Agent hereafter taken,
including any review of the affairs of any of the Loan Parties, shall be deemed
to constitute any representation or warranty by the Administrative Agent or any
Agent to any Lender; (ii) that it has made and will continue to make, without
reliance upon the Administrative Agent or any Agent, its own independent
investigation of the financial condition and affairs and its own appraisal of
the creditworthiness of each of the Loan Parties in connection with this
Agreement and the making and continuance of the Loans hereunder; and (iii)
except as expressly provided herein, that neither the Administrative Agent nor
any Agent shall have any duty or responsibility, either initially or on a
continuing basis, to provide any Lender with any credit or other information
with respect thereto, whether coming into its possession before the making of
any Loan, the issuance of any Letter of Credit or at any time or times
thereafter.

            9.4 Actions in Discretion of Agents; Instructions From the Banks.

            The Administrative Agent and each Agent agrees, upon the written
request of the Required Banks, to take or refrain from taking any action of the
type specified as being within the Administrative Agent's or such Agent's
rights, powers or discretion herein, provided that

                                    - 104 -
<PAGE>

neither the Administrative Agent nor any Agent shall be required to take any
action which exposes the Administrative Agent or any Agent to personal liability
or which is contrary to this Agreement or any other Loan Document or applicable
Law. In the absence of a request by the Required Banks, the Administrative Agent
and each Agent shall have authority, in their sole discretion, to take or not to
take any such action, unless this Agreement specifically requires the consent of
the Required Banks or all of the Banks. Any action taken or failure to act
pursuant to such instructions or discretion shall be binding on the Banks,
subject to Section 9.6 [Exculpatory Provisions, etc.]. Subject to the provisions
of Section 9.6, no Lender shall have any right of action whatsoever against the
Administrative Agent or any Agent as a result of the Administrative Agent or any
Agent acting or refraining from acting hereunder in accordance with the
instructions of the Required Banks, or in the absence of such instructions, in
the absolute discretion of the Administrative Agent or the Agents, as the case
may be.

            9.5 Reimbursement and Indemnification of Agents by the Borrower.

            The Borrower unconditionally agrees to pay or reimburse the
Administrative Agent and each Agent and hold the Administrative Agent and each
Agent harmless against (a) liability for the payment of all reasonable
out-of-pocket costs, expenses and disbursements, including fees and expenses of
outside counsel, appraisers and environmental consultants, incurred by the
Administrative Agent or any Agent (i) in connection with the development,
negotiation, preparation, printing, execution, administration, syndication,
interpretation and performance of this Agreement and the other Loan Documents,
(ii) relating to any requested amendments, waivers or consents pursuant to the
provisions hereof, (iii) in connection with the enforcement of this Agreement or
any other Loan Document or collection of amounts due hereunder or thereunder or
the proof and allowability of any claim arising under this Agreement or any
other Loan Document, whether in bankruptcy or receivership proceedings or
otherwise, (iv) in any workout or restructuring or in connection with the
protection, preservation, exercise or enforcement of any of the terms hereof or
of any rights hereunder or under any other Loan Document or in connection with
any foreclosure, collection or bankruptcy proceedings, and (v) in connection
with any Environmental Claim and/or Environmental Complaint threatened or
asserted against the Administrative Agent or any Agent or the Lenders in any way
relating to or arising out of this Agreement or any other Loan Documents
(including, without limitation, the protection, preservation, exercise or
enforcement of any of the terms hereof or of any rights or remedies hereunder or
under any other Loan Document or in connection with any foreclosure, collection
or bankruptcy or receivership proceedings or otherwise or in any workout or
restructuring) and (b) all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against the
Administrative Agent or any Agent, in its capacity as such, in any way relating
to or arising out of (i) this Agreement or any other Loan Documents or any
action taken or omitted by the Administrative Agent or any Agent hereunder or
thereunder, and (ii) any Environmental Claim and/or Environmental Complaint in
any way relating to or arising out of this Agreement or any other Loan Documents
or any action taken or omitted by the Administrative Agent or any Agent
hereunder or thereunder, provided that the Borrower shall not be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements if the same results from the
Administrative Agent's or any Agent's gross negligence or willful misconduct, or
if the Borrower was not given

                                    - 105 -
<PAGE>

notice of the subject claim and the opportunity to participate in the defense
thereof, at its expense (except that the Borrower shall remain liable to the
extent such failure to give notice does not result in a loss to the Borrower),
or if the same results from a compromise or settlement agreement entered into
without the consent of the Borrower, which shall not be unreasonably withheld.

            9.6 Exculpatory Provisions; Limitation of Liability.

            Neither the Administrative Agent, any Agent nor any of their
respective directors, officers, employees, agents, attorneys or Affiliates shall
(a) be liable to any Lender for any action taken or omitted to be taken by it or
them hereunder, or in connection herewith including pursuant to any Loan
Document, unless caused by its or their own gross negligence or willful
misconduct, (b) be responsible in any manner to any of the Lenders for the
effectiveness, enforceability, genuineness, validity or the due execution of
this Agreement or any other Loan Documents or for any recital, representation,
warranty, document, certificate, report or statement herein or made or furnished
under or in connection with this Agreement or any other Loan Documents, or (c)
be under any obligation to any of the Lenders to ascertain or to inquire as to
the performance or observance of any of the terms, covenants or conditions
hereof or thereof on the part of the Loan Parties, or the financial condition of
the Loan Parties, or the existence or possible existence of any Event of Default
or Potential Default. No claim may be made by any of the Loan Parties, any
Lender, the Administrative Agent or any Agent or any of their respective
Subsidiaries against the Administrative Agent, any Agent, any Lender or any of
their respective directors, officers, employees, agents, attorneys or
Affiliates, or any of them, for any special, indirect or consequential damages
or, to the fullest extent permitted by Law, for any punitive damages in respect
of any claim or cause of action (whether based on contract, tort, statutory
liability, or any other ground) based on, arising out of or related to any Loan
Document or the transactions contemplated hereby or any act, omission or event
occurring in connection therewith, including the negotiation, documentation,
administration or collection of the Loans, and the Borrower (for itself and on
behalf of each of its Subsidiaries), the Administrative Agent, each Agent and
each Lender hereby waives, releases and agrees never to sue upon any claim for
any such damages, whether such claim now exists or hereafter arises and whether
or not it is now known or suspected to exist in its favor. Each Lender agrees
that, except for notices, reports and other documents expressly required to be
furnished to the Lenders by the Administrative Agent or any Agent hereunder or
given to the Administrative Agent or any Agent for the account of or with copies
for the Lenders, the Administrative Agent, each Agent and each of their
respective directors, officers, employees, agents, attorneys or Affiliates shall
not have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of the Loan Parties
which may come into the possession of the Administrative Agent, any Agent or any
of their directors, officers, employees, agents, attorneys or Affiliates.

            9.7 Reimbursement and Indemnification of Agents by the Lenders.

            Each Lender agrees to reimburse and indemnify the Administrative
Agent and each Agent (to the extent not reimbursed by the Borrower and without
limiting the Obligation of the Borrower to do so) in proportion to its Revolving
Credit Ratable Share, from and against all

                                    - 106 -
<PAGE>

liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
reasonable costs, expenses or disbursements, including attorneys' fees and
disbursements, and costs of appraisers and environmental consultants, of any
kind or nature whatsoever which may be imposed on, incurred by or asserted
against the Administrative Agent, the Agents, or any of them in their respective
capacities as such, in any way relating to or arising out of this Agreement or
any other Loan Documents or any action taken or omitted by the Administrative
Agent or any Agent hereunder or thereunder, provided that no Lender shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements (a) if
the same results from the Administrative Agent's or any Agent's gross negligence
or willful misconduct, as the case may be, or (b) if such Lender was not given
notice of the subject claim and the opportunity to participate in the defense
thereof, at its expense (except that such Lender shall remain liable to the
extent such failure to give notice does not result in a loss to the Lender), or
(c) if the same results from a compromise and settlement agreement entered into
without the consent of such Lender, which shall not be unreasonably withheld. In
addition, each Lender agrees promptly upon demand to reimburse the
Administrative Agent and each Agent (to the extent not reimbursed by the
Borrower and without limiting the Obligation of the Borrower to do so) in
proportion to its Revolving Credit Ratable Share, for all amounts due and
payable by the Borrower to the Administrative Agent or the Agents, as the case
may be in connection with the periodic audit of the Loan Parties' books, records
and business properties by the Administrative Agent or the Agents.

            9.8 Reliance by Agents.

            The Administrative Agent and each Agent shall be entitled to rely
upon any writing, telegram, telex or teletype message, resolution, notice,
consent, certificate, letter, cablegram, statement, order or other document or
conversation by telephone or otherwise believed by it to be genuine and correct
and to have been signed, sent or made by the proper Person or Persons, and upon
the advice and opinions of counsel and other professional advisers selected by
the Administrative Agent or any Agent. The Administrative Agent and each Agent
shall be fully justified in failing or refusing to take any action hereunder
unless it shall first be indemnified to its 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.

            9.9 Notice of Default.

            Neither the Administrative Agent nor any Agent shall be deemed to
have knowledge or notice of the occurrence of any Potential Default or Event of
Default unless such person has received written notice from a Bank or the
Borrower referring to this Agreement, describing such Potential Default or Event
of Default and stating that such notice is a "notice of default."

            9.10 Notices.

            Each of the Administrative Agent and each Agent agrees to promptly
send to each Bank a copy of all notices received from the Borrower pursuant to
the provisions of this Agreement or the other Loan Documents promptly upon
receipt thereof. The Administrative

                                    - 107 -
<PAGE>

Agent shall promptly notify the Borrower and the other Banks of each change in
the Base Rate and the effective date thereof.

            9.11 Banks in Their Individual Capacities.

            With respect to its Revolving Credit Commitment, the Revolving
Credit Loans, the Swing Loans, the issuance of any Letter of Credit made by it
and any other rights and powers given to it as a Bank hereunder or under any of
the other Loan Documents, the Administrative Agent and each Agent shall have the
same rights and powers hereunder as any other Bank and may exercise the same as
though it were not the Administrative Agent or an Agent, as the case may be, and
the term "Banks" shall, unless the context otherwise indicates, include the
Administrative Agent and each Agent in its individual capacity. PNC Bank and its
Affiliates, JPMorgan Chase and its Affiliates, each other Agent and its
Affiliates, and each of the Lenders and their respective Affiliates may, without
liability to account, except as prohibited herein, make loans to, accept
deposits from, discount drafts for, act as trustee under indentures of, and
generally engage in any kind of banking or trust business with the Loan Parties
and their Affiliates, in the case of the Administrative Agent or any Agent, as
though it were not acting as Administrative Agent or Agent, as the case may be,
hereunder and in the case of each Lender, as though such Lender were not a
Lender hereunder. The Lenders acknowledge that, pursuant to such activities, the
Administrative Agent or its Affiliates or any Agent or its respective Affiliates
may (i) receive information regarding the Loan Parties (including information
that may be subject to confidentiality obligations in favor of the Loan Parties)
and acknowledge that neither the Administrative Agent nor any Agent shall be
under any obligation to provide such information to them, and (ii) accept fees
and other consideration from the Loan Parties for services in connection with
this Agreement and otherwise without having to account for the same to the
Lenders.

            9.12 Holders of Notes.

            The Administrative Agent and each Agent may deem and treat any payee
of any Note as the owner thereof for all purposes hereof unless and until
written notice of the assignment or transfer thereof shall have been filed with
the Administrative Agent and the Agents. Any request, authority or consent of
any Person who at the time of making such request or giving such authority or
consent is the holder of any Note shall be conclusive and binding on any
subsequent holder, transferee or assignee of such Note or of any Note or Notes
issued in exchange therefor.

            9.13 Equalization of Lenders.

            The Lenders and the holders of any participations in any Commitments
or Loans or other rights or obligations of a Lender hereunder agree among
themselves that, with respect to all amounts received by any Lender or any such
holder for application on any Obligation hereunder or under any such
participation, whether received by voluntary payment, by realization upon
security, by the exercise of the right of set-off or banker's lien, by
counterclaim or by any other non-pro rata source, equitable adjustment will be
made in the manner stated in the following sentence so that, in effect, all such
excess amounts will be shared ratably among the Lenders and such holders in
proportion to their interests in payments on the Loans, except as

                                    - 108 -
<PAGE>

otherwise provided in Sections 3.4.3 [Administrative Agent's and Lender's
Rights], 4.4.2 [Replacement of a Lender] or 4.5 [Additional Compensation in
Certain Circumstances]. The Lenders or any such holder receiving any such amount
shall purchase for cash from each of the other Lenders an interest in such
Lender's Loans in such amount as shall result in a ratable participation by the
Lenders and each such holder in the aggregate unpaid amount of the Loans,
provided that if all or any portion of such excess amount is thereafter
recovered from the Lender or the holder making such purchase, such purchase
shall be rescinded and the purchase price restored to the extent of such
recovery, together with interest or other amounts, if any, required by law
(including court order) to be paid by the Lender or the holder making such

            9.14 Successor Agents.

            Any Agent or the Administrative Agent (i) may resign as Agent or
Administrative Agent, as the case may be or (ii) shall resign if such
resignation is requested by the Required Banks (if the Agent or Administrative
Agent is a Bank, such Agent's or Administrative Agent's Loans and Commitment
shall be considered in determining whether the Required Banks have requested
such resignation) or required by Section 4.4.2 [Replacement of a Lender], in
either case of (i) or (ii) by giving not less than thirty (30) days' prior
written notice to the Borrower. If any Agent or the Administrative Agent shall
resign under this Agreement, then either (a) the Required Banks shall appoint
from among the Banks a successor to such Agent or Administrative Agent, as the
case may be, for the Banks, subject to the consent of the Borrower, such consent
not to be unreasonably withheld (provided, that, no consent of the Borrower
shall be required during any period when an Event of Default exists and is
continuing), or (b) if a successor Agent or Administrative Agent shall not be so
appointed and approved within the thirty (30) day period following an Agent's or
the Administrative Agent's notice, as the case may be, to the Banks of its
resignation, then the resigning Administrative Agent or resigning Agent, as the
case may be, shall appoint, with the consent of the Borrower, such consent not
to be unreasonably withheld (provided, that, no consent of the Borrower shall be
required during any period when an Event of Default exists and is continuing), a
successor who shall be a Bank shall serve as Administrative Agent or Agent, as
the case may be, until such time as the Required Banks appoint and the Borrower
consents to the appointment of a successor to such resigning Administrative
Agent or Agent. Upon its appointment pursuant to either clause (a) or (b) above,
such successor Administrative Agent or Agent shall succeed to the rights, powers
and duties of the resigning Administrative Agent or Agent, as the case may be,
and the terms "Agent" and "Administrative Agent" shall mean such successor Agent
or Administrative Agent, as the case may be, effective upon its appointment, and
the former Administrative Agent's or Agent's rights, powers and duties as an
Agent or Administrative Agent shall be terminated without any other or further
act or deed on the part of such former Agent or Administrative Agent or any of
the parties to this Agreement. After the resignation of the Administrative Agent
or any Agent hereunder, the provisions of this Section 9 shall inure to the
benefit of such former Administrative Agent and each former Agent, and such
former Administrative Agent and each former Agent shall not by reason of such
resignation be deemed to be released from liability for any actions taken or not
taken by it while it was Administrative Agent or an Agent under this Agreement.

            9.15 Administrative Agent's Fees.

            The Borrower shall pay to the Administrative Agent a nonrefundable
fee (the "Administrative Agent's Fee") for the Administrative Agent's services
hereunder under the terms of a letter (the "Administrative Agent's Letter")
between the Borrower and the Administrative Agent, as amended from time to time.

            9.16 Availability of Funds.

            The Administrative Agent may assume that each Lender has made or
will make the proceeds of a Loan available to the Administrative Agent unless
the Administrative Agent shall have been notified by such Lender on or before
the later of (1) the close of business on the Business Day preceding the
Borrowing Date with respect to such Loan or two (2) hours before the time on
which the Administrative Agent actually funds the proceeds of such Loan to the
Borrower (whether using its own funds pursuant to this Section 9.16 or using
proceeds deposited with the Administrative Agent by the Lenders and whether such
funding occurs before or after the time on which Lenders are required to deposit
the proceeds of such Loan with the Administrative Agent). The Administrative
Agent may, in reliance upon such assumption (but shall not be required to), make
available to the Borrower a corresponding amount. If such corresponding amount
is not in fact made available to the Administrative Agent by such Lender, the
Administrative Agent shall be entitled to recover such amount on demand from
such Lender (or, if such Lender fails to pay such amount forthwith upon such
demand from the Borrower) together with interest thereon, in respect of each day
during the period commencing on the date such amount was made available to the
Borrower and ending on the date the Administrative Agent recovers such amount,
at a rate per annum equal to (i) the Federal Funds Effective Rate during the
first three (3) days after such interest shall begin to accrue and (ii) the
applicable interest rate in respect of such Loan after the end of such three-day
period.

            9.17 Calculations.

            In the absence of gross negligence or willful misconduct, the
Administrative Agent shall not be liable for any error in computing the amount
payable to any Lender whether in respect of the Loans, fees or any other amounts
due to the Lenders under this Agreement. In the event an error in computing any
amount payable to any Lender is made, the Administrative Agent, the Borrower and
each affected Lender shall, forthwith upon discovery of such error, make such
adjustments as shall be required to correct such error, and any compensation
therefor will be calculated at the Federal Funds Effective Rate.

            9.18 Certain Releases of Guarantors and Collateral.

            It is expressly agreed that, upon the written request of the
Borrower (accompanied by such certificates and other documentation as the
Administrative Agent may reasonably request) the Administrative Agent on behalf
of the Lenders and without any consent or action by any Lender, may, so long as
no Event of Default exists after giving effect thereto, release: (i) any
Collateral, Additional Collateral or any Guarantor from a Guaranty Agreement, in
either case, in connection with any sale, transfer, lease, disposition, merger,
Permitted Receivables Financing or

                                    - 110 -
<PAGE>

other transaction permitted by this Agreement, or (ii) any Subsidiary from the
Guaranty Agreement if such Subsidiary is no longer a Significant Subsidiary.

            9.19 Beneficiaries.

            Except as expressly provided herein, the provisions of this Section
9 are solely for the benefit of the Administrative Agent, each Agent and the
Lenders, and the Loan Parties shall not have any rights to rely on or enforce
any of the provisions hereof. In performing its functions and duties under this
Agreement, the Administrative Agent and each Agent shall act solely as the
Administrative Agent or Agent, as the case may be, of the Lenders and do not
assume and shall not be deemed to have assumed any obligation toward or
relationship of agency or trust with or for any of the Loan Parties.

            9.20 No Reliance on Administrative Agent's Customer Identification
Program.

            Each Lender acknowledges and agrees that neither such Lender, nor
any of its Affiliates, participants or assignees, may rely on the Administrative
Agent to carry out such Lender's, Affiliate's, participant's or assignee's
customer identification program, or other obligations required or imposed under
or pursuant to the USA Patriot Act or the regulations thereunder, including the
regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the
"CIP Regulations"), or any other Anti-Terrorism Law, including any programs
involving any of the following items relating to or in connection with any of
the Loan Parties, their Affiliates or their agents, the Loan Documents or the
transactions hereunder or contemplated hereby: (1) any identity verification
procedures, (2) any recordkeeping, (3) comparisons with government lists, (4)
customer notices or (5) other procedures required under the CIP Regulations or
such other Laws.

                        10. MISCELLANEOUS

            10.1 Modifications, Amendments or Waivers.

            With the written consent of the Required Banks, the Administrative
Agent, acting on behalf of all the Lenders, and the Borrower, on behalf of the
Loan Parties, may from time to time enter into written agreements amending or
changing any provision of this Agreement or any other Loan Document or the
rights of the Lenders or the Loan Parties hereunder or thereunder, or may grant
written waivers or consents to a departure from the due performance of the
Obligations of the Loan Parties hereunder or thereunder. Any such agreement,
waiver or consent made with such written consent shall be effective to bind all
the Lenders and the Loan Parties; provided, that no such agreement, waiver or
consent may be made which will:

                  10.1.1 Increase of Revolving Credit Commitments; Extension of
                        Expiration Date; Modification of Terms of Payment.

                  Without the written consent of all Banks, increase the amount
of the Revolving Credit Commitment of any Bank hereunder, extend the Expiration
Date, whether or not any Revolving Credit Loans are outstanding, extend the time
for payment of principal or interest of any Revolving Credit Loan, the
Commitment Fee or any other fee payable to any Bank

                                    - 111 -
<PAGE>

which has a Revolving Credit Commitment, reduce the principal amount of or the
rate of interest borne by any Revolving Credit Loan, reduce the rate of the
Commitment Fee or any other fee payable to any Bank which has a Revolving Credit
Commitment;

                  10.1.2 Release of Guarantor.

                  Except as set forth in Section 9.18, without the written
consent of all Banks, release any Guarantor from its Obligations under the
Guaranty Agreement or any of the Collateral or any of the Additional Collateral
for any of the Loan Parties' Obligations; or

                  10.1.3 Miscellaneous.

                  Without the written consent of all Banks, amend Sections 4.2
[Pro Rata Treatment of Banks], 9.6 [Exculpatory Provisions, etc.] or 9.13
[Equalization of Lenders] or this Section 10.1, alter any provision regarding
the pro rata treatment of the Lenders, change the definition of Required Banks,
or change any requirement providing for the Lenders, all the Lenders or the
Required Banks to authorize the taking of any action hereunder; provided,
further, that no agreement, waiver or consent which would modify the interests,
rights or obligations of any Agent in its capacity shall be effective without
the written consent of such Agent; no agreement, waiver or consent which would
modify the interests, rights or obligations of the Administrative Agent in its
capacity shall be effective without the written consent of the Administrative
Agent; and no agreement, waiver or consent which would modify the interests,
rights or obligations of any Issuing Bank as the issuer of Letters of Credit
shall be effective without the written consent of such Issuing Bank.

            10.2 No Implied Waivers; Cumulative Remedies; Writing Required.

            No course of dealing and no delay or failure of the Administrative
Agent, any Agent or any Lender in exercising any right, power, remedy or
privilege under this Agreement or any other Loan Document shall affect any other
or future exercise thereof or operate as a waiver thereof, nor shall any single
or partial exercise thereof or any abandonment or discontinuance of steps to
enforce such a right, power, remedy or privilege preclude any further exercise
thereof or of any other right, power, remedy or privilege. The rights and
remedies of the Administrative Agent, each Agent and the Lenders under this
Agreement and any other Loan Documents are cumulative and not exclusive of any
rights or remedies which they would otherwise have. Any waiver, permit, consent
or approval of any kind or character on the part of any Lender of any breach or
default under this Agreement or any such waiver of any provision or condition of
this Agreement must be in writing and shall be effective only to the extent
specifically set forth in such writing.

            10.3 Reimbursement and Indemnification of Lenders by the Borrower;
Taxes.

            The Borrower agrees unconditionally upon demand to pay or reimburse
to each Lender (other than the Administrative Agent and the Agents, as to which
the Borrower's Obligations are set forth in Section 9.5 [Reimbursement and
Indemnification of Agents by the Borrower]) and to save such Lender harmless
against (i) liability for the payment of all reasonable out-of-pocket costs,
expenses and disbursements (including fees and expenses of

                                    - 112 -
<PAGE>

outside counsel) for each Lender (except with respect to (A) and (B) below),
incurred by such Lender (a) in connection with the administration and
interpretation of this Agreement, and other instruments and documents to be
delivered hereunder, (b) relating to any amendments, waivers or consents
pursuant to the provisions hereof, (c) in connection with the enforcement of
this Agreement or any other Loan Document, or collection of amounts due
hereunder or thereunder or the proof and allowability of any claim arising under
this Agreement or any other Loan Document, whether in bankruptcy or receivership
proceedings or otherwise, (d) in any workout or restructuring or in connection
with the protection, preservation, exercise or enforcement of any of the terms
hereof or of any rights hereunder or under any other Loan Document or in
connection with any foreclosure, collection or bankruptcy proceedings, and (e)
in connection with any Environmental Claim and/or Environmental Complaint
threatened or asserted against the Lenders in any way relating to or arising out
of this Agreement or any other Loan Documents (including, without limitation,
the protection, preservation, exercise or enforcement or any of the terms hereof
or of any rights or remedies hereunder or under any other Loan Document or in
connection with any foreclosure, collection or bankruptcy or receivership
proceedings or otherwise or in any workout or restructuring), or (ii) all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against such Lender, in its capacity as
such, in any way relating to or arising out of (y) this Agreement or any other
Loan Documents or any action taken or omitted by such Lender hereunder or
thereunder, and (z) any Environmental Claim and/or Environmental Complaint in
any way relating to or arising out of this Agreement or any other Loan Documents
or any action taken or omitted by such Lender hereunder or thereunder, provided
that the Borrower shall not be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements (A) if the same results from such Lender's gross
negligence or willful misconduct, or (B) if the Borrower was not given notice of
the subject claim and the opportunity to participate in the defense thereof, at
its expense (except that the Borrower shall remain liable to the extent such
failure to give notice does not result in a loss to the Borrower), or (C) if the
same results from a compromise or settlement agreement entered into without the
consent of the Borrower, which shall not be unreasonably withheld. None of the
Agents nor any Lender shall be liable for any damages arising from the use by
unauthorized persons of information or other materials sent through electronic,
telecommunications, or other information transmission systems that are
intercepted by such persons. None of the Agents nor any Lender shall be liable
or responsible to the Borrower or other party hereto for any special, indirect,
consequential or punitive damages in connection with the Loans or otherwise
under or in connection with the Loan Documents, the transactions contemplated
thereby or any of their respective obligations thereunder. The Lenders will
attempt to minimize the fees and expenses of legal counsel for the Lenders which
are subject to reimbursement by the Borrower hereunder by considering the use of
one law firm to represent the Lenders, the Administrative Agent, and the Agents
if appropriate under the circumstances. The Borrower agrees unconditionally to
pay all stamp, document, transfer, recording or filing taxes or fees and similar
impositions now or hereafter determined by the Administrative Agent, any Agent
or any Lender to be payable in connection with this Agreement or any other Loan
Document, and the Borrower agrees unconditionally to save the Administrative
Agent, each Agent and the Lenders harmless from and against any and all present
or future claims, liabilities

                                    - 113 -
<PAGE>

or losses with respect to or resulting from any omission to pay or delay in
paying any such taxes, fees or impositions.

            10.4 Holidays.

            Whenever payment of a Loan to be made or taken hereunder shall be
due on a day which is not a Business Day, such payment shall be due on the next
Business Day and such extension of time shall be included in computing interest
and fees, except that the Revolving Credit Loans and Swing Loans shall be due on
the Business Day preceding the Expiration Date if the Expiration Date is not a
Business Day. Whenever any payment or action to be made or taken hereunder
(other than payment of the Loans) shall be stated to be due on a day which is
not a Business Day, such payment or action shall be made or taken on the next
following Business Day (except as provided in Section 3.2 [Interest Periods]
with respect to Interest Periods under the Euro-Rate Option), and such extension
of time shall not be included in computing interest or fees, if any, in
connection with such payment or action.

            10.5 Funding by Branch, Subsidiary or Affiliate.

                  10.5.1 Notional Funding.

                  Each Lender shall have the right from time to time, without
notice to the Borrower, to deem any branch, Subsidiary or Affiliate (which for
the purposes of this Section 10.5 shall mean any corporation or association
which is directly or indirectly controlled by or is under direct or indirect
common control with any corporation or association which directly or indirectly
controls such Lender) of such Lender to have made, maintained or funded any Loan
to which the Euro-Rate Option applies at any time, provided that immediately
following (on the assumption that a payment were then due from the Borrower to
such other office), and as a result of such change, the Borrower would not be
under any greater financial obligation pursuant to Section 4.5 [Additional
Compensation in Certain Circumstances] than it would have been in the absence of
such change. Notional funding offices may be selected by each Lender without
regard to such Lender's actual methods of making, maintaining or funding the
Loans or any sources of funding actually used by or available to such Lender.

                  10.5.2 Actual Funding.

                  Each Lender shall have the right from time to time to make or
maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such
Lender to make or maintain such Loan subject to the last sentence of this
Section 10.5.2. If any Lender causes a branch, Subsidiary or Affiliate to make
or maintain any part of the Loans hereunder, all terms and conditions of this
Agreement shall, except where the context clearly requires otherwise, be
applicable to such part of the Loans to the same extent as if such Loans were
made or maintained by such Lender, but in no event shall any Lender's use of
such a branch, Subsidiary or Affiliate to make or maintain any part of the Loans
hereunder cause such Lender or such branch, Subsidiary or Affiliate to incur any
cost or expenses payable by the Borrower hereunder or require the Borrower to
pay any other compensation to any Lender (including any expenses incurred or
payable pursuant to Section 4.5 [Additional Compensation in Certain
Circumstances]) which would otherwise not be incurred.

            10.6 Notices.

            All notices, requests, demands, directions and other communications
(as used in this Section 10.6, collectively referred to as "notices") given to
or made upon any party hereto under the provisions of this Agreement shall be by
telephone or in writing (including telex or facsimile communication) unless
otherwise expressly permitted hereunder and shall be delivered or sent by telex
or facsimile to the respective parties at the addresses and numbers set forth
under their respective names on Schedule 1.1(B) hereof or in accordance with any
subsequent unrevoked written direction from any party to the others. All notices
shall, except as otherwise expressly herein provided, be effective (a) in the
case of telex or facsimile, when received, (b) in the case of hand-delivered
notice, when hand-delivered, (c) in the case of telephone, when telephoned,
provided, however, that in order to be effective, telephonic notices must be
confirmed in writing no later than the next day by letter, facsimile or telex,
(d) if given by mail, four (4) days after such communication is deposited in the
mail with first-class postage prepaid, return receipt requested, and (e) if
given by any other means (including by air courier), when delivered; provided,
that notices to the Agents or to the Administrative Agent shall not be effective
until received. Any Lender giving any notice to the Borrower shall
simultaneously send a copy thereof to the Administrative Agent, and the
Administrative Agent shall promptly notify the other Lenders of the receipt by
it of any such notice. Any notice delivered to the Borrower shall be deemed to
be notice to the Loan Parties and shall be binding upon all of the Loan Parties.

            10.7 Severability.

            The provisions of this Agreement are intended to be severable. If
any provision of this Agreement shall be held invalid or unenforceable in whole
or in part in any jurisdiction, such provision shall, as to such jurisdiction,
be ineffective to the extent of such invalidity or unenforceability without in
any manner affecting the validity or enforceability thereof in any other
jurisdiction or the remaining provisions hereof in any jurisdiction.

            10.8 Governing Law.

            Each Letter of Credit and Section 2.9 [Letter of Credit Subfacility]
shall be subject to the Uniform Customs and Practice for Documentary Credits
(1993 Revision), International Chamber of Commerce Publication No. 500, as the
same may be revised or amended from time to time, and to the extent not
inconsistent therewith, the internal laws of the Commonwealth of Pennsylvania
without regard to its conflict of laws principles, and the balance of this
Agreement shall be deemed to be a contract under the Laws of the Commonwealth of
Pennsylvania and for all purposes shall be governed by and construed and
enforced in accordance with the internal laws of the Commonwealth of
Pennsylvania without regard to its conflict of laws principles.

            10.9 Prior Understanding.

            This Agreement, the Third Amendment Fee Letter and the other Loan
Documents supersede all prior understandings and agreements, whether written or
oral, between the parties hereto and thereto relating to the transactions
provided for herein and therein, including any prior confidentiality agreements
and commitments.

            10.10 Duration; Survival.

            All representations and warranties of the Borrower contained herein
or made by any Loan Party in connection herewith shall survive the making of
Loans and issuance of Letters of Credit and shall not be waived by the execution
and delivery of this Agreement, any investigation by the Administrative Agent,
any Agent or the Lenders, the making of Loans, issuance of Letters of Credit, or
payment in full of the Loans. All covenants and agreements of the Borrower
contained in Sections 7.1 [Affirmative Covenants], 7.2 [Negative Covenants] and
7.3 [Reporting Requirements] herein shall continue in full force and effect from
and after the date hereof so long as the Borrower may borrow or request Letters
of Credit hereunder and until termination of the Commitments and payment in full
of the Loans and expiration or termination of all Letters of Credit. All
covenants and agreements of the Borrower contained herein relating to the
payment of principal, interest, premiums, additional compensation or expenses
and indemnification, including those set forth in Section 4 [Payments] and
Sections 9.5 [Reimbursement and Indemnification of Agents by the Borrower], 9.7
[Reimbursement and Indemnification of Agents by Lenders] and 10.3 [Reimbursement
and Indemnification of Lenders by the Borrower, etc.], shall survive payment in
full of the Loans, expiration or termination of the Letters of Credit and
termination of the Commitments.

            10.11 Successors and Assigns.

                  10.11.1 Binding Effect; Assignments by Borrower.

                  This Agreement shall be binding upon and shall inure to the
benefit of the Lenders, the Agents, the Administrative Agent, the Issuing Banks,
the Borrower and their respective successors and assigns, except that the
Borrower may not assign or transfer any of its rights and Obligations hereunder
or any interest herein without the consent of all of the Banks.

                  10.11.2 Assignments and Participations by Banks.

                  (a) This Section shall apply to any assignment or
participation by a Lender of its Loans, Letters of Credit Outstanding or
Commitments. Each Bank may, at its own cost, make assignments of all or any part
of its Revolving Credit Commitment and Revolving Credit Loans, and its Revolving
Credit Ratable Share of Letters of Credit Outstanding to one or more banks or
other entities, subject to the consent of the Borrower (which consent shall not
be required during any period in which an Event of Default exists), the
applicable Issuing Banks, and the Administrative Agent with respect to any
assignee, such consents not to be unreasonably withheld, provided, however, that
consent of neither the Borrower, the Administrative Agent nor any Issuing Bank
shall be required for any assignment by a Lender to an Affiliate of such Lender
(so long as the assigning Lender provides notice of such assignment to the
Administrative Agent and pays to the Administrative Agent the $3,500 service fee
as hereinafter provided in this Section 10.11.2(a)), and provided further, that
assignments may not be made in amounts less than $5,000,000 (unless such
assignment is an assignment of all of a Bank's Loans or Commitments or unless
such assignment is made by a Lender to an Affiliate of such Lender or to another
Lender). Each Lender may, at its own cost, grant participations in all or any
part of its Revolving

                                    - 116 -
<PAGE>

Credit Commitment and the Revolving Credit Loans made by it and of its Revolving
Credit Ratable Share of Letters of Credit Outstanding to one or more banks or
other entities, without the consent of any party hereto. In the case of an
assignment of all or any portion of a Revolving Credit Commitment, upon receipt
by the Administrative Agent of the Assignment and Assumption Agreement, the
assignee shall have, to the extent of such assignment (unless otherwise provided
therein), the same rights, benefits and obligations as it would have if it had
been a signatory Bank hereunder, the Commitments in Section 2.1 shall be
adjusted accordingly, and upon surrender of any Revolving Credit Note subject to
such assignment, the Borrower shall execute and deliver a new Revolving Credit
Note to the assignee in an amount equal to the amount of the Revolving Credit
Commitment assumed by it and a new Revolving Credit Note to the assigning Bank
in an amount equal to the Revolving Credit Commitment retained by it hereunder.
Any assigning Lender shall pay to the Administrative Agent a service fee in the
amount of $3,500 for each assignment, which amount shall not be subject to
reimbursement or indemnification by the Borrower. In the case of a
participation, the participant shall have only the rights specified in Section
8.2.3 [Set-Off] (the participant's rights against the selling Lender in respect
of such participation to be those set forth in the agreement executed by such
Lender in favor of the participant relating thereto and not to include any
voting rights except with respect to changes of the type referenced in Sections
10.1.1, 10.1.2 and 10.1.3), all of such Lender's obligations under this
Agreement or any other Loan Document shall remain unchanged, and all amounts
payable by any Loan Party hereunder or thereunder shall be determined as if such
Lender had not sold such participation.

                  (b) Designation.

                        (i) Notwithstanding anything to the contrary contained
herein, any Lender (a "Designating Lender") may grant to one or more special
purpose funding vehicles (each, an "SPV"), identified as such in writing from
time to time by the Designated Lender to the Administrative Agent and the
Borrower, the option to provide to the Borrower all or any part of any Revolving
Credit Loan that such Designating Lender would otherwise be obligated to make to
the Borrower pursuant to this Agreement; provided that (x) nothing herein shall
constitute a commitment by any SPV to make any Revolving Credit Loan, (y) if an
SPV elects not to exercise such option or otherwise fails to provide all or any
part of such Revolving Credit Loan, the Designating Lender shall be obligated to
make such Revolving Credit Loan pursuant to the terms hereof and (z) the
Designating Lender shall remain liable for any indemnity or other payment
obligation with respect to its Commitment hereunder. The making of a Revolving
Credit Loan by an SPV hereunder shall utilize the Commitment of the Designating
Lender to the same extent, and as if, such Revolving Credit Loan were made by
such Designating Lender.

                        (ii) As to any Revolving Credit Loans or portion thereof
made by it, each SPV shall have all the rights that a Lender making such
Revolving Credit Loans or portion thereof would have had under this Agreement;
provided, however, that each SPV shall have granted to its Designating Lender an
irrevocable power of attorney, to deliver and receive all communications and
notices under this Agreement (and any Loan Documents) and to exercise, on such
SPV's behalf, all of such SPV's voting rights under this Agreement. No
additional Note shall be required to evidence the Revolving Credit Loans or
portion thereof made

                                    - 117 -
<PAGE>

by an SPV; and the related Designating Lender shall be deemed to hold its Note
as agent for such SPV to the extent of the Revolving Credit Loans or portion
thereof funded by such SPV. In addition, any payments for the account of any SPV
shall be paid to its Designating Lender as agent for such SPV. Notwithstanding
any term or condition hereof, no SPV, unless it shall have become a Lender
hereunder in accordance with the terms of Section 10.11.2(a), shall be a party
hereto or have any right to vote or give or withhold its consent under this
Agreement. The Administrative Agent shall have no duty or obligation to give any
notices required to be delivered hereunder to any SPV.

                        (iii) Each party hereto hereby agrees that no SPV shall
be liable for any indemnity or payment under this Agreement for which a Lender
would otherwise be liable. In furtherance of the foregoing, each party hereto
hereby agrees (which agreements shall survive the termination of this Agreement)
that, prior to the date that is one year and one day after the later of (x)
payment in full of all outstanding commercial paper or other senior indebtedness
of any SPV, (y) the payment in full of all Revolving Credit Loans, and (z) the
termination of all Commitments, it will not institute against, or join any other
person in instituting against, such SPV any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings under the laws of the United
States or any State thereof, provided that the Designating Lender for each SPV
hereby agrees to indemnify, save and hold harmless each other party hereto for
any loss, cost, damage and expense arising out of the inability to institute any
such proceeding against such SPV.

                        (iv) In addition, notwithstanding anything to the
contrary contained in this Section 10.11.2(b) or otherwise in this Agreement
(other than the proviso set forth directly below in this Section 10.11.2(b), any
SPV may (y) with notice to, but without the prior written consent of the
Borrower or the Administrative Agent, at any time and without paying any
processing fee therefor, assign or participate all or a portion of its interest
in any Revolving Credit Loans to the Designating Lender or to any financial
institutions providing liquidity and/or credit support to or for the account of
such SPV to support the funding or maintenance of Revolving Credit Loans and (z)
disclose on a confidential basis any non public information relating to its
Revolving Credit Loans to any rating agency, commercial paper dealer or provider
of any surety, guarantee or credit or liquidity enhancements to such SPV;
provided, however, that in no event may any non-public financial information
provided by the Borrower under Section 7.3 [Reporting Requirements] be provided
by any SPV to any other Person. In no event shall the Borrower be obligated to
pay to any SPV that has made a Revolving Credit Loan any greater amount than the
Borrower would have been obligated to pay under this Agreement if the
Designating Lender had made such Revolving Credit Loan. This Section 10.11.2(b)
may not be amended without the written consent of any Designating Lender
affected thereby.

                  10.11.3 Non-U.S. Assignees and Participants.

                  Any assignee or participant which is not incorporated under
the Laws of the United States of America or a state thereof shall deliver to the
Borrower and the Administrative Agent the form of certificate described in
Section 10.17 relating to federal income tax withholding. Each Lender may
furnish any publicly available information concerning any Loan Party or its
Subsidiaries and any other information concerning any Loan Party or its

                                    - 118 -
<PAGE>

Subsidiaries in the possession of such Lender from time to time to assignees and
participants (including prospective assignees or participants), provided that
such assignees and participants agree to be bound by the provisions of Section
10.12 [Confidentiality].

                  10.11.4 Assignments by Lenders to Federal Reserve Banks.

                  Notwithstanding any other provision in this Agreement, any
Lender may at any time pledge or grant a security interest in all or any portion
of its rights under this Agreement, its Notes (if any) and the other Loan
Documents to any Federal Reserve Bank without notice to or consent of the
Borrower and the Administrative Agent. No such pledge or grant of a security
interest shall release the transferor Lender of its obligations hereunder or
under any other Loan Document. In no event shall such Federal Reserve Bank, as a
result of such pledge or grant of a security interest, be considered to be a
"Lender" hereunder or be entitled to require the assigning Lender to take or
omit to take any action hereunder. For avoidance of doubt, the parties to this
Agreement acknowledge that the provisions of this Section 10.11 concerning
assignments relate only to absolute assignments and that such provisions do not
prohibit assignments creating security interests, including any pledge or
assignment by a Lender to any Federal Reserve Bank in accordance with applicable
law.

            10.12 Confidentiality.

                  10.12.1 General.

                  The Agents, the Administrative Agent and the Lenders each

Subsidiaries which is nonpublic and confidential or proprietary in nature

confidential), except as provided below, and to use such information only in
connection with their respective capacities under this Agreement and for the
purposes contemplated hereby. The Agents, the Administrative Agent and the
Lenders shall be permitted to disclose such information (i) to outside legal
counsel, accountants and other professional advisors who need to know such
information in connection with the execution, administration and enforcement of
this Agreement, subject to the agreement of such Persons to maintain the
confidentiality, (ii) to assignees and participants as contemplated by Section
10.11 [Successors and Assigns], (iii) to any direct or indirect contractual
counterparty in any swap, hedge, securitization or similar agreement or such
contractual counterparty's professional advisor (so long as such contractual
counterparty or professional advisor to such contractual counterparty agrees to
be bound by the provisions of this Section 10.12) (iv) to the extent requested
by any bank regulatory authority or, with notice to the Borrower as permitted by
applicable Law, as otherwise required by applicable Law or by any subpoena or
similar legal process, or in connection with any investigation or proceeding
arising out of the transactions contemplated by this Agreement, (v) if it
becomes publicly available other than as a result of a breach of this Agreement
or becomes available from a source not known to be subject to confidentiality
restrictions, (vi) any nationally recognized rating agency that requires access
to information about the Lender's investment portfolio, (vii) in connection with
the exercise, preservation or protection of any right or remedy hereunder or
under the other Loan Documents, applicable law or in equity, or (viii) if the
Borrower shall have consented to such disclosure. Notwithstanding anything

                                    - 119 -
<PAGE>

herein to the contrary, the information subject to this Section 10.12.1 shall
not include, and the Administrative Agent and each Lender may disclose without
limitation of any kind, any information with respect to the "tax treatment" and
"tax structure" (in each case, within the meaning of Income Tax Regulation
Section 1.6011-4) of the transactions contemplated hereby and all materials of
any kind (including opinions or other tax analyses) that are provided to the
Administrative Agent or such Lender relating to such tax treatment and tax
structure; provided that with respect to any document or similar item that in
either case contains information concerning the tax treatment or tax structure
of the transaction as well as other information, this sentence shall only apply
to such portions of the document or similar item that relate to the tax
treatment or tax structure of the Loans, Letters of Credit and transactions
contemplated hereby.

                  10.12.2 Sharing Information With Affiliates of the Lenders.

                  The Borrower acknowledges that from time to time financial
advisory, investment banking and other services may be offered or provided to
the Borrower or one or more of its Affiliates (in connection with this Agreement
or otherwise) by any Lender or by one or more Subsidiaries or Affiliates of such
Lender and the Borrower (on its own behalf and on behalf of its Subsidiaries)
hereby authorizes each Lender to share any information delivered to such Lender
by the Borrower and its Subsidiaries pursuant to this Agreement, or in
connection with the decision of such Lender to enter into this Agreement, to any
such Subsidiary or Affiliate of such Lender, it being understood that any such
Subsidiary or Affiliate of any Lender receiving such information shall be bound
by the provisions of Section 10.12.1 as if it were a Lender hereunder. Such
authorization shall survive the repayment of the Loans and other Obligations and
the termination of the Commitments.

            10.13 Counterparts.

            This Agreement may be executed by different parties hereto on any
number of separate counterparts, each of which, when so executed and delivered,
shall be an original, and all such counterparts shall together constitute one
and the same instrument.

            10.14 Agent's or Lender's Consent.

            Whenever the Administrative Agent's, any Agent's or any Lender's
consent is required to be obtained under this Agreement or any of the other Loan
Documents as a condition to any action, inaction, condition or event, the
Administrative Agent, each Agent and each Lender shall be authorized to give or
withhold such consent in its sole and absolute discretion and to condition its
consent upon the giving of additional collateral, the payment of money or any
other matter.

            10.15 Exceptions.

            The representations, warranties and covenants contained herein shall
be independent of each other, and no exception to any representation, warranty
or covenant shall be deemed to be an exception to any other representation,
warranty or covenant contained herein unless expressly provided, nor shall any
such exceptions be deemed to permit any action or omission that would be in
contravention of applicable Law.

            10.17 Certifications from Lenders and Participants.

                  10.17.1 Tax Withholding.

            Each Lender or assignee or participant of a Lender that is not
incorporated under the Laws of the U. S. or a state thereof (and, upon the
written request of the Administrative Agent, each other Lender or assignee or
participant of a Lender) agrees that it will deliver to each of the Borrower and
the Administrative Agent two (2) duly completed appropriate valid Withholding
Certificates (as defined under Section 1.1441-1(c)(16) of the Income Tax
Regulations) certifying its status (i.e., U.S. or foreign Person) and, if
appropriate, making a claim of reduced, or exemption from, U.S. withholding tax
on the basis of an income tax treaty or an exemption provided by the Internal
Revenue Code. The term "Withholding Certificate" includes a Form W-9; Form
W-8BEN; Form W-8ECI; or, Form W-8IMY, and the related statements and
certifications as required under Section 1.1441-1(c)(3) of the Income Tax
Regulations; a statement described in Section 1.871-14(c)(2)(v) of the Income
Tax Regulations; or, any other certificates under the Internal Revenue Code or
Income Tax Regulations that certify or establish the status of a payee or
beneficial owner as a U.S. or foreign Person. Each Lender, assignee or
participant required to deliver to the Borrower and the Administrative Agent a
valid Withholding Certificate pursuant to the preceding sentence shall deliver
such valid Withholding Certificate as follows: (A) each Lender which is a party
hereto on the Restatement Effective Date shall deliver such valid Withholding
Certificate at least five (5) Business Days prior to the first date on which any
interest or fees are payable by the Borrower hereunder for the account of such
Lender; (B) each assignee or participant shall deliver such valid Withholding
Certificate at least five (5) Business Days before the effective date of such
assignment or participation (unless the Administrative Agent in its sole
discretion shall permit such assignee or participant to deliver such Withholding
Certificate less than five (5) Business Days before such date in which case it
shall be due on the

                                    - 121 -
<PAGE>

date specified by the Administrative Agent). Each Lender, assignee or
participant which so delivers a valid Withholding Certificate further undertakes
to deliver to each of the Borrower and the Administrative Agent two (2)
additional copies of such Withholding Certificate (or a successor form) on or
before the date that such Withholding Certificate expires or becomes obsolete or
after the occurrence of any event requiring a change in the most recent
Withholding Certificate so delivered by it, and such amendments thereto or
extensions or renewals thereof as may be reasonably requested by the Borrower or
the Administrative Agent. Notwithstanding the submission of a Withholding
Certificate claiming a reduced rate of, or exemption from U.S. withholding tax,
the Administrative Agent shall be entitled to withhold U. S. federal income
taxes at the full withholding rate, unless the Lender, assignee or participant
establishes pursuant to the foregoing that it is entitled to an exemption or
that it is subject to a reduced rate, or if in its reasonable judgment the
Administrative Agent is not required to do so under the due diligence
requirements imposed upon a withholding agent under Section 1.1441-7(b) of the
Income Tax Regulations. The Administrative Agent shall be indemnified under
Section 1.1461-1(e) of the Income Tax Regulations against any claims and demands
of any Lender or assignee or participant of a Lender for the amount of any tax
it deducts and withholds in accordance with regulations under Section 1441 of
the Internal Revenue Code.

                  10.17.2 USA Patriot Act.

            Each Lender or assignee or participant of a Lender that is not
incorporated under the Laws of the U. S. or a state thereof (and is not excepted
from the certification requirement contained in Section 313 of the USA Patriot
Act and the applicable regulations because it is both (i) an affiliate of a
depository institution or foreign bank that maintains a physical presence in the
U.S. or foreign county, and (ii) subject to supervision by a banking authority
regulating such affiliated depository institution or foreign bank) shall deliver
to the Administrative Agent the certification, or, if applicable,
recertification, certifying that such Lender is not a "shell" and certifying to
other matters as required by Section 313 of the USA Patriot Act and the
applicable regulations: (1) within 10 days after the Second Restatement
