              Inspection, Record Keeping and Reporting Requirements

         Section 8.1 -- Contemporaneous Access to the Premises. Independent
Contractor acknowledges and agrees that AWVMC or its designee may place and
install or cause to be placed and installed on the Premises various structures,
equipment and materials, and AWVMC may carry on, either directly or through its

desirable for its own purposes as long as it does not interfere with Independent
Contractor's ability to perform the Work under this Agreement. AWVMC shall
ensure that all activity on the Premises by AWVMC or its designee shall be
conducted in accordance with all applicable laws, rules and regulations,
including, without limitation, all MSHA requirements.

projections for the next succeeding 6-month period and submit such plans and
projections to AWVMC for its written approval; provided, however, the proposed
mining plans and projections submitted on or before the Commencement Date shall
show plans and projections to December, 2001, only. The mining plans and

Contractor is or may be required to deliver to AWVMC and the entire area
proposed to be mined by Independent Contractor, and the mining plans and
projections shall make suitable provisions for the reasonable and proper removal
of all of the mineable and merchantable coal from the Premises. Independent

AWVMC may, among other things, verify its title to or right to mine Coal from
the areas of the Premises which may be subject to the proposed mining plans and
projections. Upon approval of the mining plans and projections, Independent
Contractor shall diligently follow such plans and projections in performing the

acknowledges that in performing the Work under this Agreement it may have access
to proprietary information and trade secrets of a confidential nature pertaining
to AWVMC, its affiliates and their businesses, the Premises, the Coal and the
BayBeck Mine. Independent Contractor agrees that it shall treat all maps, plans,
data, reports, drilling logs, core samples, leases and other information
relating to AWVMC and its business, the Premises, the Coal or the BayBeck Mine
(the "Information") as confidential, and it shall not divulge, transmit or

Work performed under the Agreement. Independent Contractor shall not jeopardize
any of the governmental permits held, if any, by AWVMC, Independent Contractor,
or its and their affiliates, contractors or lessees. Independent Contractor
shall be totally and solely responsible for and shall hold harmless, indemnify
and defend AWVMC from and against any and all liability for any citations,
assessments, fines, damages, withdrawal orders or civil and criminal penalties
assessed against either Independent Contractor or AWVMC which are caused,

Independent Contractor, its employees, agents, contractors or representatives.
In the event that AWVMC or Independent

                                      -23-
<PAGE>

Contractor is assessed, fined or penalized for any violation arising out of
Independent Contractor's conduct, or the conduct of its agents, contractors or

the future to Independent Contractor for Work performed under the Agreement an
amount sufficient to cover any such assessments, fines and penalties, together

except a validly asserted Force Majeure Event, with the Monthly Designations as
set forth in the Delivery Schedules twice during any six (6) consecutive month
period.

         c. If any action by Independent Contractor in performing the Work under
this Agreement, complying with any of the terms under this Agreement, or the
presence of any agent, employee, contractor or representative of Independent
Contractor upon the Premises, or the execution of this Agreement by it shall
cause interference with or disrupt or threaten to interfere with or disrupt
AWVMC's operations in any manner or the operations of any of AWVMC's affiliates,
subsidiaries, or any other contractor(s), at any location whatsoever, for any
reason, and if such interference, disruption or threat continues for ten (10)
days after Independent Contractor's receipt of written notice from AWVMC;

or if two such directives are issued in any calendar year, regardless of their
duration;

                                      -30-

         Section 11.2 - Termination Based Upon an Event of Default. In addition
to and not in limitation of its right to terminate this Agreement as provided in
other sections of this Agreement, AWVMC shall have the right to terminate this
Agreement upon the occurrence of an Event of Default by giving written notice to
Independent Contractor of such termination.

         Section 11.3 - Right to Cure. If Independent Contractor is in breach or
default of any of the terms or conditions of this Agreement, whether or not said
breach or default gives rise to an Event of Default, AWVMC shall have the right,
but not the duty, to make any payment or to perform any act or complete or
correct the Work required of Independent Contractor under this Agreement and, in
exercising such right, to incur, for and on behalf of Independent Contractor,
necessary or incidental costs and expenses, including reasonable attorneys'
fees. In exercising the foregoing right, AWVMC may offset and deduct all
payments made and all costs and expenses incurred against such sums of money, if
any, due or to become due to Independent Contractor under this Agreement and
proceed against Independent Contractor under the provisions of Section 10.1
relating to indemnity. AWVMC's right to cure Independent Contractor's default or
breach as described in this Section 11.3 shall not imply any obligation on the
part of AWVMC to make any payment or to perform any act required of Independent
Contractor, and the exercise of such right by AWVMC shall not constitute a
release or waiver of any default or breach by Independent Contractor.

         Section 11.4 -- Waiver of Performance or Default. The failure of either
AWVMC or Independent Contractor to insist in any one or more instances upon
strict performance of any of the covenants, terms or conditions imposed upon or
assumed by either party under this Agreement, or the failure of AWVMC or

not sell or otherwise transfer its ownership interest in the Premises if such
sale or other transfer would have a material adverse effect on Independent

of this Agreement.

         Section 13.6 -- Headings. The headings appearing in this Agreement are

         Section 13.9 - Force Majeure.

         (a) If AWVMC or Independent Contractor is rendered wholly or partly
unable to perform its obligations under this Agreement by reason of a Force
Majeure Event, AWVMC or Independent Contractor, as the case may be, will be
excused from whatever performance is affected by the Force Majeure Event to the
extent so affected, provided that (i) the party relying on the Force Majeure
Event notifies the other as soon as practicable of the Force Majeure Event and
its cause; (ii) the suspension of performance is of no longer duration than is
required by the Force Majeure Event; (iii) no obligations of either party which
arose before the Force Majeure Event causing the suspension of performance are
excused as a result of the Force Majeure Events; and (iv) the non-performing
party exercises due diligence to remove the cause of the

                                      -36-
<PAGE>

Force Majeure Event or to lessen its effect and resumes performance at the
earliest practicable time.

         (b) In no event will this Section 13.9 be construed to relieve either
party of any obligations hereunder solely because of increased costs or other
adverse economic consequences that may be incurred through the performance of
such obligations of the parties. Notwithstanding the above, adverse economic
consequences from governmental actions will be considered a Force Majeure Event
if it results from an item listed in the definition of a Force Majeure Event.
For the purposes of this Agreement only, the term "Force Majeure Event" shall
mean or refer to any act or event that (i) prevents AWVMC or its coal sales
agent from selling any of the Coal mined or to be mined hereunder at a
reasonable profit or otherwise perform its obligations under any agreement for
the sale or re-sale of Coal, and (ii) any other act or event which is beyond the
reasonable control of AWVMC or Independent Contractor and which renders
performance of this Agreement, in whole or in part impossible. Such acts or
events include, without limitation, an act of God, nuclear emergency, explosion,
fire, epidemic, landslide, lightning, earthquake, flood or similar cataclysmic
occurrence, an act of public enemy, war, blockade, insurrection, strike, riot,
civil disturbance, restrictions or restraints imposed by law or by rule,
regulation or order of governmental authorities, whether federal, state or
local, delays or interruptions in transportation, major breakdown or other
restrictions on the use of equipment, or any cause, whether of the same of a
different nature, existing or future, foreseen or unforeseen. Unless resulting
from any of the events listed in the preceding sentence, economic hardship or
failure by Independent Contractor to produce Coal in such quantities as required
under this Agreement will not constitute a Force Majeure Event.

                                      -37-
<PAGE>

         (c) No Force Majeure Event will invalidate this Agreement and, on
termination of the Force Majeure Event, deliveries of Coal will resume pursuant
to the terms and conditions hereof. Shipments not made or not accepted due to a
Force Majeure Event will not be made up unless AWVMC in its sole discretion
elects to do so.

         (d) The term of this Agreement shall, in AWVMC's sole discretion, be
extended for a period equal to the sum of all periods during which a Force
Majeure prevented either party from performing this Agreement.

         IN WITNESS WHEREOF, the parties have caused their corporate names to be
signed hereto by their officers duly authorized.

                               THE CREDIT FACILITY

     2.01 Revolving Credit Facility Commitment.

          (a) Revolving Credit Loans. Subject to the terms and conditions and
relying upon the representations and warranties set forth in this Agreement, the
Notes and the other Loan Documents, the Banks severally (but not jointly) agree
to make loans (the "Revolving Credit Loans") to the Borrowers at any time or
from time to time on or after the Closing Date and to and including the Business
Day immediately preceding the Expiry Date in an aggregate principal amount, when
combined with the aggregate Letter of Credit Undrawn Availability, which shall
not exceed at any one time outstanding Forty Million and 00/100 Dollars
($40,000,000.00) (the "Revolving Credit Facility Commitment"); provided,
however, that no Bank shall be required to make Revolving Credit Loans (or
participate in the issuance of Letters of Credit) in an aggregate principal
amount outstanding at any one time exceeding such Bank's Commitment Percentage.
The Revolving Credit Loans shall be made pro rata in accordance with each Bank
Commitment Percentage. Within the limits of time and amount set forth in this
Section 2.01, and subject to the provisions of this Agreement including, without
limitation, the Banks' right to demand repayment of the Revolving Credit Loans
upon the occurrence of an Event of Default, the Borrowers may borrow, repay and
reborrow under this Section 2.01; provided, however, that if the Borrowers
prepay any Libor Rate Loan on a day other than the last day of the applicable
Interest Period for such Libor Rate Loan, then the Borrowers shall comply with
the terms and conditions of Section 2.11(c) with respect to such prepayment.

          (b) Revolving Credit Note. The joint and several obligations of the
Borrowers to repay the unpaid principal amount of the Revolving Credit Loans
made to the Borrowers by each Bank and to pay interest on the unpaid principal
amount thereof is evidenced in part by the Revolving Credit Notes of the
Borrowers, dated the Closing Date, in substantially the form of Exhibit "A"
attached hereto and made a part hereof, with the blanks appropriately filled.
Each Revolving Credit Note shall be payable to the order of a Bank in a
principal amount equal to such Bank's Revolving Credit Commitment. The executed
Revolving Credit Notes will be delivered by the Borrowers to the Banks on the
Closing Date.

          (c) Making, Continuing or Converting of Revolving Credit Loans.
Subject to the terms and conditions set forth in this Agreement and the other
Loan Documents, and provided that the Borrowers have satisfied all applicable
conditions specified in Article IV hereof, the Banks shall make Revolving Credit
Loans to the Borrowers which, as selected by the Borrowers pursuant to this
Section 2.01(c), shall be Prime Rate Loans or Libor Rate Loans. In addition,
subject to the terms and conditions set forth below, the Borrowers shall have
the opportunity to (i) convert Prime Rate Loans into Libor Rate Loans, (ii)
convert Libor Rate Loans into Prime Rate Loans or (iii) continue Libor Rate
Loans as Libor Rate Loans for additional Interest Periods.

               (i) Each Revolving Credit Loan that is made as or converted (from
a Libor Rate Loan) into a Prime Rate Loan shall be made or converted on such
Business Day and in such amount as an Authorized Representative of the Borrowers
shall request by written or telephonic notice (confirmed promptly, but in no
event later than one Business Day thereafter, in writing) received by the Agent
no later than 10:00 a.m. (Pittsburgh, Pennsylvania time) on the date of
requested disbursement of or conversion into the requested Prime Rate Loan.
Subject to the terms and conditions of this Agreement, on each borrowing date,
the Agent shall make the proceeds of the Prime Rate Loan available to the
Borrowers at the Agent's Office in immediately available funds not later than
2:00 p.m. (Pittsburgh, Pennsylvania time). Unless an Authorized Representative
of the Borrowers shall provide the Agent with the required written notice to
convert a Prime Rate Loan into a Libor Rate Loan on or prior to the third (3rd)
Business Day prior to the date of requested conversion, such Prime Rate Loan
shall automatically continue as a Prime Rate Loan.

               (ii) Each Revolving Credit Loan that is made as, continued as or
converted (from a Prime Rate Loan) into a Libor Rate Loan shall be made,
continued or converted, on such Business Day, in such amount (greater than or
equal to One Million and 00/100 Dollars ($1,000,000.00); provided, however, that
any amount in excess of One Million and 00/100 Dollars ($1,000,000.00) may only
be in increments of Five Hundred Thousand and 00/100 Dollars ($500,000.00)) and
with such an Interest Period as an Authorized Representative of the Borrowers
shall request by written or telephonic notice (confirmed promptly, but in no
event later than one Business Day thereafter, in writing) received by the Agent
no later than 10:00 a.m. (Pittsburgh, Pennsylvania time) on the third (3rd)
Business Day prior to the requested date of disbursement of, continuation of or
conversion into the requested Libor Rate Loan. Subject to the terms and
conditions of this Agreement, on each borrowing date, the Agent shall make the
proceeds of the Libor Rate Loan available to the Borrowers at the Agent's Office
in immediately available funds, no later than 10:00 a.m. (Pittsburgh,
Pennsylvania time). In addition, in the event that the Borrowers desire to
continue a Libor Rate Loan for an additional Interest Period, an Authorized
Representative of the Borrowers shall provide the Agent with written notice
thereof on or prior to the third (3rd) Business Day prior to the expiration of
the applicable Interest Period. In the event that an Authorized Representative
of the Borrowers fails to provide the Agent with the required written or
telephonic notice (confirming promptly, but in no event later than one Business
Day thereafter, in writing) on or prior to the third (3rd) Business Day prior to
the expiration of the applicable Interest Period for a Libor Rate Loan, the
Borrowers shall be deemed to have given written notice that such Loan shall be
converted into a Prime Rate Loan on the last day of the applicable Interest
Period. Notwithstanding anything contained herein to the contrary, there shall
not be more than four (4) Revolving Credit Loans that are Libor Rate Loans
outstanding at any time. Each written notice of any Libor Rate Loan shall be
irrevocable and binding on the Borrowers and the Borrowers shall indemnify the
Agent and the Banks against any loss or expense incurred by the Banks as a
result of any failure by the Borrowers to consummate such transaction calculated
as set forth in Section 2.11(c) hereof.

               (iii) Each Bank hereby authorizes the Agent to make all Loans
that are requested by the Borrowers on the proposed date of disbursement. Upon
receipt of a request to make, continue or convert a Revolving Credit Loan
hereunder, the Agent shall promptly, but in no event later than 12:00 noon
(Pittsburgh, Pennsylvania time) on the date of the receipt of such request,
advise each of the Banks of the proposed date of disbursement,

                                      -14-
<PAGE>

continuation or conversion, the amount and type of each such Revolving Credit
Loan, the applicable Interest Period and the Bank's Commitment amount thereof.
Each Bank shall remit its Commitment Percentage of the principal amount of each
Revolving Credit Loan to the Agent at the Office of the Agent in immediately
available funds no later than 2:00 p.m. (Pittsburgh, Pennsylvania time) on the
applicable date of disbursement. If the amount of such Bank's Commitment
Percentage is not made available to the Agent by such Bank on the applicable
borrowing date, the Agent shall not be required to fund such Bank's Commitment
Percentage of the Revolving Credit Loans on the applicable borrowing date;
provided, however, the Agent may elect in its sole discretion to fund such
Bank's Commitment Percentage on the applicable borrowing date, and such Bank
shall be subject to the repayment obligations set forth below.

               (iv) The Agent may assume that each Bank has made or will make
the proceeds of a Loan available to the Agent unless the Agent shall have been
notified by such Bank on or before the later of (a) the close of business on the
Business Day preceding the applicable borrowing date with respect to the Loan,
or (b) one (1) hour before the time on which the Agent actually funds the
proceeds of such Loan to the Borrowers (whether using its own funds pursuant to
this subsection or using proceeds deposited with the Agent by the Banks and
whether such funding occurs before or after the time on which the Banks are
required to deposit the proceeds of such Loan with the Agent). The Agent may, in
reliance upon such assumption (but shall not be required to), make available to
the Borrowers a corresponding amount. If such corresponding amount is not in
fact made available to the Agent by such Bank, the Agent shall be entitled to
recover such amount on demand from such Bank (or, if such Bank fails to pay such
amount, forthwith upon such demand from the Borrowers) together with interest
thereon, in respect of each day during the period commencing on the date such
amount was made available to the Borrowers and ending on the date the Agent
recovers such amount, at a rate per annum equal to (y) the Prime Rate during the
first three (3) days after such interest shall begin to accrue and (z) the
Applicable Rate in respect of such Loan after the end of such three (3) day
period.

          (d) Maximum Principal Balance of Revolving Credit Loans and Letter of
Credit Undrawn Availability. The sum of the aggregate principal amount of all
Revolving Credit Loans outstanding and the aggregate Letter of Credit Undrawn
Availability shall not exceed the amount of the Revolving Credit Facility
Commitment. The Borrowers agree that if at any time the sum of the aggregate
principal amount of all Revolving Credit Loans outstanding and the aggregate
Letter of Credit Undrawn Availability exceeds the amount of the Revolving Credit
Facility Commitment (the "Excess Amount"), the Borrowers shall promptly, but in
no event later than one Business Day thereafter, pay to the Agent (for the
ratable benefit of the Banks) such Excess Amount. If not sooner paid, the entire
principal balance of all outstanding Revolving Credit Loans, together with all
unpaid accrued interest thereon, and all other sums and costs owed to the Agent
and the Banks by the Borrowers pursuant to this Agreement, shall be immediately
due and payable on the Expiry Date, without notice, presentment or demand of any
kind.

     2.02 Interest Rates.

          (a) Interest on the Revolving Credit Loans. Subject to the terms and
conditions of this Agreement, the aggregate outstanding principal balance of the
Revolving

                                      -15-

Credit Loans shall be, at the option of the Borrowers as selected pursuant to
Section 2.01(c) hereof, (x) Prime Rate Loans which shall bear interest for each
day at the rates set forth below or (y) Libor Rate Loans which shall bear
interest during each applicable Interest Period at the rates set forth below:

               (i) Subject to the terms and conditions of this Agreement, on the
Closing Date and through the day immediately preceding the first Incentive
Pricing Effective Date, (x) Revolving Credit Loans that are Prime Rate Loans
shall bear interest for each day at a rate per annum equal to the Prime Rate
plus the Applicable Prime Margin corresponding to Tier II as set forth below and
(y) Revolving Credit Loans that are Libor Rate Loans shall bear interest during
each applicable Interest Period at a rate per annum equal to the Libor Rate plus
the Applicable Libor Margin corresponding to Tier II as set forth below;

               (ii) Subject to the terms and conditions of this Agreement,
during each Fiscal Quarter, in accordance with Section 5.01(b) hereof, the
Borrowers shall submit to the Agent and the Banks quarterly financial statements
(the Fiscal Quarter in which such financial statements are required to be
received by the Agent and the Banks is the "Reporting Quarter") as of the last
day of the Fiscal Quarter immediately preceding such Reporting Quarter (with
respect to any Reporting Quarter, the Fiscal Quarter immediately preceding such
Reporting Quarter is the "Measurement Quarter"). Upon receipt of such quarterly
financial statements by the Agent and the Banks in accordance with Section
5.01(b), the Borrowers' Leverage Ratio shall be calculated as of the last day of
the Measurement Quarter ending June 30, 2001 and as of the last day of each
Measurement Quarter thereafter. From the first day of the first full calendar
month following the Agent's and the Banks' receipt of such quarterly financial
statements (the "Incentive Pricing Effective Date") until the next Incentive
Pricing Effective Date, (x) Prime Rate Loans shall bear interest for each day at
a rate per annum equal to the Prime Rate plus the applicable margin determined
by reference to the Borrowers' Leverage Ratio as set forth below (the
"Applicable Prime Margin") and (y) Libor Rate Loans shall bear interest during
each applicable Interest Period at a rate per annum equal to the Libor Rate plus
the applicable margin determined by reference to the Borrowers' Leverage Ratio
as set forth below (the "Applicable Libor Margin"):

               (iii) Subject to the terms and conditions of this Agreement, in
the event that the Borrowers fail to timely deliver the financial statements
required by Section 5.01(b) hereof, the Applicable Margin shall be the amount
corresponding to Tier V until the delivery of such financial statements.

          (b) Calculation of Interest and Fees; Adjustment to Prime Rate.
Interest on the Loans, unpaid fees and other sums payable hereunder shall be
computed on the basis of a year of three hundred sixty (360) days and paid for
the actual number of days elapsed. In the event of any change in the Prime Rate,
the rate of interest applicable to each Prime Rate Loan shall be adjusted to
immediately correspond with such change; provided, however, that any interest
rate charged hereunder shall not exceed the Maximum Rate.

          (c) Interest After Maturity or Default; Interest Laws. Upon the
occurrence and during the continuance of an Event of Default, (i) the unpaid
principal amount of the Loans or any portion thereof, accrued interest thereon,
any fees or any other sums payable hereunder shall thereafter until paid in full
bear interest at a rate per annum equal to the Applicable Rate plus two percent
(2.00%); (ii) each Libor Rate Loan shall automatically convert into a Prime Rate
Loan at the end of the applicable Interest Period; and (iii) no Loans may be
made as, continued as or converted into a Libor Rate Loan. Notwithstanding any
provisions to the contrary contained in this Agreement or any other Loan
Document, the Borrowers shall not be required to pay, and the Banks shall not be
permitted to collect, any amount of interest in excess of the maximum amount of
interest permitted by applicable Law ("Excess Interest"). If any Excess Interest
is provided for or determined by a court of competent jurisdiction to have been
provided for in this Agreement or in any other Loan Document, then, in such
event: (1) the provisions of this subsection shall govern and control; (2) the
Borrowers shall not be obligated to pay any Excess Interest; (3) any Excess
Interest that any Bank may have received hereunder shall be, at the Majority
Banks' option, (a) applied as a credit against the outstanding principal balance
of the Indebtedness evidenced by the Notes or accrued and unpaid interest
thereon (not to exceed the maximum amount permitted by Law), (b) refunded to the
payor thereof, or (c) any combination of the foregoing; (4) the interest rate(s)
provided for herein shall be automatically reduced to the maximum lawful rate
allowed from time to time under applicable Law (the "Maximum Rate"), and this
Agreement and the other Loan Documents shall be deemed to have been and shall
be, reformed and modified to reflect such reduction; and (5) the Borrowers shall
have no action against the Agent or the Banks for any damages arising out of the
payment or collection of any Excess Interest.

     2.03 Interest Payments. The Borrowers shall pay to the Agent for the
ratable account of the Banks interest on the aggregate outstanding balance of
the Revolving Credit Loans which are Prime Rate Loans in arrears, on October 1,
2001 and on the first day of each calendar month thereafter through and
including the Expiry Date. The Borrowers shall pay to the Agent for the ratable
account of the Banks interest on the unpaid principal balance of the Revolving
Credit Loans that are Libor Rate Loans on the earlier of (i) the last day of the
applicable Interest Period for such Loan or (ii) for such Loans with an
applicable Interest Period exceeding three (3) months, on each and every three
(3) month anniversary of each such Loan during the period from the Closing Date
to and including the Expiry Date. After maturity of any part of the Loans
(whether upon the occurrence of an Event of Default, by acceleration or
otherwise), interest on such part of the Loans shall be immediately due and
payable upon delivery by the Agent of an invoice for such interest without
further notice, presentment, or demand of any kind.

     2.04 Fees.

          (a) The Borrowers shall pay to the Agent for the ratable account of
the Banks

               (i) A non-refundable up-front fee, on or before the Closing Date,
in the amount equal to One Hundred Thousand and 00/100 Dollars ($100,000.00);

               (ii) A commitment fee on the unused portion of the amount of the
Revolving Credit Facility Commitment during the period from the date of this
Agreement to the Expiry Date, payable quarterly in arrears beginning on October
1, 2001 and continuing on the first (1st) day of each January, April, July and
October thereafter and on the Expiry Date. Such fee shall be equal to the amount
by which the amount of the Revolving Credit Facility Commitment has exceeded the
average daily closing principal balance of the sum of the Revolving Credit Loans
and the Letter of Credit Undrawn Availability during the preceding calendar
quarter, multiplied by three-eighths of one percent (0.375%), multiplied by a
fraction, the numerator of which is the actual number of days in such calendar
quarter and the denominator of which is 360; and

               (iii) The Letter of Credit Commission pursuant to Section 2.06
hereof.

          (b) The Borrowers shall pay to the Agent for its own account the fees
described in the first sentence of Section 2.06 hereof and in that certain fee
letter of even date herewith by and among the Borrowers and the Agent in the
amounts, and at the times, specified therein.

     2.05 Agreement to Issue Letters of Credit. From time to time during the
period from the Closing Date to the thirtieth (30th) day preceding the Expiry
Date, subject to the further terms and conditions hereof, including those
required in connection with the making of Revolving Credit Loans, the Agent
shall issue standby or trade letters of credit (collectively with the Existing
Letters of Credit, the "Letters of Credit") for the account of the Borrowers in
an amount not to exceed Ten Million and 00/100 Dollars ($10,000,000.00) in the
aggregate as a subfacility of the Revolving Credit Facility Commitment;
provided, however, that on any date on which the Borrowers request a Letter of
Credit, and after giving effect to the Letter of Credit Face Amount of such
Letter of Credit, the sum of all Revolving Credit Loans outstanding and the
Letter of Credit Undrawn Availability shall not exceed the Revolving Credit
Facility Commitment. All such Letters of Credit shall be issued by the Agent in
accordance with its then current practice relating to the issuance of letters of
credit including, but not limited to, the execution and delivery to the Agent of
applications and agreements required by the Agent and the payment by the
Borrowers of all applicable fees with respect thereto. As of the date hereof,
those letters of credit set forth on Schedule 2.05 hereof (collectively, the
"Existing Letters of Credit"), which were issued under the Prior Loan Agreement
and are outstanding on the date hereof, will be deemed to be Letters of Credit
issued and outstanding hereunder.

     Each request for a Letter of Credit shall be delivered to the Agent no
later than 10:00 a.m. (Pittsburgh, Pennsylvania time) on the second (2nd)
Business Day, or such

                                      -18-
<PAGE>

shorter period as may be agreed to by the Agent, prior to the proposed date of
issuance. Each such request shall be in a form acceptable to the Agent and
specify the Letter of Credit Face Amount thereof, the account party, the
beneficiary, the intended date of issuance, the expiry date thereof, and the
nature of the transaction to be supported thereby. All such Letters of Credit
shall be issued by the Agent in accordance with its then current practice
relating to the issuance of Letters of Credit including, but not limited to, the
execution and delivery to the Agent of applications and agreements required by
the Agent and the payment by the Borrowers of all applicable fees required by
Section 2.06 hereof. Immediately upon the issuance of each Letter of Credit,
each Bank shall be deemed to, and hereby irrevocably and unconditionally agrees
to, purchase from the Agent a participation in such Letter of Credit and each
drawing thereunder in an amount equal to such Bank's Pro Rata Share of the
Letter of Credit Face Amount of such Letter of Credit. The Agent shall promptly,
but in any event not later than the next Business Day, provide to each Bank
notice of each such request for a Letter of Credit by the Borrowers.

     2.06 Letter of Credit Fees. The Borrowers shall pay to the Agent for its
own account (a) a fronting fee for each Letter of Credit issued hereunder, such
fee shall be equal to one-eighth of one percent (0.125%) of the daily average
Letter of Credit Undrawn Availability during the preceding calendar quarter,
payable quarterly in arrears beginning on October 1, 2001 and continuing on the
first (1st) day of each January, April, July and October thereafter and on the
Expiry Date, (b) the Agent's standard amendment fees for each Letter of Credit
issued hereunder, such fee to be paid on the date of the amendment of such
Letter of Credit and (c) any reasonable out-of-pocket expenses and costs
incurred by the Agent for the issuance of any Letter of Credit issued hereunder,
such fees to be paid on the day of issuance of such Letter of Credit. The
Borrowers shall also pay to the Agent for the ratable account of the Banks a fee
(the "Letter of Credit Commission") calculated daily equal to the Letter of
Credit Undrawn Availability on each day multiplied by the applicable margin for
such day determined by reference to the Borrowers' Leverage Ratio as set forth
in Section 2.02(a)(ii) hereof (the "Applicable L/C Margin"), such fee to be paid
quarterly in arrears beginning on October 1, 2001 and continuing on the first
(1st) day of each January, April, July and October thereafter and on the Expiry
Date. Notwithstanding the foregoing, after the occurrence and during the
continuance of an Event of Default, the Letter of Credit Commission shall be
increased by two percent (2.00%) per annum.

     2.07 Payments Under Letters of Credit. Upon a draw under any Letter of
Credit, the Borrowers shall immediately, but in any event not later than the end
of such Business Day, reimburse the Agent for such drawing under a Letter of
Credit. If (i) the Borrowers shall not have reimbursed the Agent for such
drawing under such Letter of Credit by the end of such Business Day, (ii) the
Agent must for any reason return or disgorge such reimbursement, or (iii) the
Borrowers are required to make a payment under Section 7.02(a)(ii) hereof and
fail to make such payment, then the amount of each unreimbursed drawing under
such Letter of Credit and payment required to be made under Section 7.02(a)(ii)
hereof shall automatically be converted into a Revolving Credit Loan which shall
be a Prime Rate Loan made on the date of such drawing for all purposes of this
Agreement. The Borrowers' obligation to reimburse the Agent with respect to each
drawing under a Letter of Credit shall be absolute and unconditional.

     2.08 Period of Issuance and Term of Letters of Credit. Letters of Credit
shall only be issued by the Agent for the account of the Borrowers for such
terms which expire at least ten (10) days prior to the Expiry Date.

                                      -19-
<PAGE>

     2.09 Booking of Libor Rate Loans. Each Bank may make, carry or transfer
Libor Rate Loans at, to or for the account of, any of its branch offices or the
office of an affiliate of such Bank; provided, however, that no such action
shall result in increased liability or cost to the Borrowers, including any
increased liability or cost pursuant to Section 2.11 or 2.12 hereof.

     2.10 Assumptions Concerning Funding of Libor Rate Loans. Calculation of all
amounts payable to each Bank under Section 2.11(c) shall be made as though each
Bank had actually funded its relevant Libor Rate Loan through the purchase of a
Libor deposit bearing interest at the Libor Rate in an amount equal to the
amount of that Libor Rate Loan and having maturity comparable to the relevant
Interest Period and through the transfer of such Libor deposit from an offshore
office to a domestic office in the United States of America; provided, however,
that each Bank may fund each of its Libor Rate Loans in any manner it sees fit
and the foregoing assumption shall be utilized only for the calculation of
amounts payable under Section 2.11(c).

     2.11 Additional Costs.

          (a) If, due to either (i) the introduction of, or any change in, or in
the interpretation of, any Law or (ii) the compliance with any guideline or
request from any central bank or other Official Body (whether or not having the
force of Law), there shall be any increase in the cost to, or reduction in
income receivable by, a Bank of making, funding or maintaining Loans (or
commitments to make the Loans), then the Borrowers shall from time to time, upon
demand by such Bank made within a reasonable time after such Bank's
determination thereof, pay to the Agent for the account of such Bank additional
amounts sufficient to reimburse such Bank for any such additional costs or
reduction in income. All such additional amounts shall be determined by such
Bank in good faith using appropriate attribution and averaging methods
ordinarily employed by such Bank. A certificate of such Bank submitted to the
Borrowers in good faith as to the amount of such additional costs shall be
presumptive evidence of such amount. Within ten (10) Business Days after the
Agent or such Bank notifies the Borrowers in writing of any such additional
costs pursuant to this Section 2.11(a), the Borrowers may (A) repay in full all
Loans of any types so affected then outstanding, together with interest accrued
thereon to the date of such repayment, or (B) convert all Loans of any types so
affected then outstanding into Loans of any other type not so affected upon not
less than four (4) Business Days' notice to the Agent. If any such repayment or
conversion of any Libor Rate Loan occurs on any day other than the last day of
the applicable Interest Period for such Loan, the Borrowers also shall pay to
the Agent for the ratable account of the Banks such additional amounts as set
forth in Section 2.11(c).

          (b) If either (i) the introduction of, or any change in, or in the
interpretation of, any Law or (ii) the compliance with any guideline or request
from any central bank or other Official Body (whether or not having the force of
Law), affects the amount of capital required to be maintained by any Bank or any
corporation controlling any Bank and such Bank reasonably determines in good
faith that the amount of such capital is increased by or based upon the
existence of the Loans (or commitment to make the Loans), then, within ten (10)
Business Days of demand by such Bank, the Borrowers shall pay to the Agent for
the account of such Bank from time to time as specified by such Bank, additional
amounts sufficient to compensate such Bank in the light of such circumstances,
to the extent that such Bank reasonably determines in good faith such increase
in capital to be allocable to the existence of

                                      -20-
<PAGE>

such Bank's Loans (or commitment to make the Loans). Any such demand by a Bank
must be made by such Bank within a reasonable time. A certificate of such Bank
in good faith submitted to the Borrowers as to such amounts shall be presumptive
evidence of such amounts. Within ten (10) Business Days after the Agent or such
Bank notifies the Borrowers in writing of any such additional costs pursuant to
this Section 2.11(b), the Borrowers may (A) repay in full all Loans of any types
so affected then outstanding, together with interest accrued thereon to the date
of such prepayment, or (B) convert all Loans of any types so affected then
outstanding into Loans of any other type not so affected upon not less than four
(4) Business Days' notice to such Bank. If any such prepayment or conversion of
any Libor Rate Loan occurs on any day other than the last day of the applicable
Interest Period for such Loan, the Borrowers also shall pay to the Agent for the
ratable account of the Banks such additional amounts as set forth in Section
2.11(c).

          (c) If the Borrowers shall repay any Libor Rate Loan on a day other
than the last day of the applicable Interest Period for such Loan (whether such
repayment is (i) permitted by this Section 2.11 or Section 2.12, (ii) permitted
as a result of the failure of the Borrowers to consummate a transaction after
providing notice as set forth in Section 2.01(c)(ii), (iii) otherwise permitted
by a Bank, or (iv) otherwise required under the terms of this Agreement), the
Borrowers shall within ten (10) Business Days of written demand pay to the Agent
for the ratable benefit of the Banks such additional amounts reasonably
determined by the Banks in good faith to be sufficient to indemnify the Banks
against any loss, cost, or expense incurred by the Banks as a result of such
prepayment including, without limitation, any loss (including loss of
anticipated profits), costs or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by the Banks to fund such Loan,
and a certificate as to the amount of any such loss, cost or expense submitted
by any Bank to the Borrowers in good faith shall be presumptive evidence of such
amount.

     2.12 Illegality; Impracticability. Notwithstanding any other provision
contained in this Agreement, if: (a) it is unlawful, or any central bank or
other Official Body shall determine that it is unlawful, for the Agent or any
Bank to perform its obligations hereunder to make, continue, or convert Loans
hereunder; or (b) on any date on which a Libor Rate would otherwise be set, any
Bank shall have in good faith determined (which determination shall be
conclusive absent manifest error) that (i) adequate and reasonable means do not
exist for ascertaining a Libor Rate, (ii) a contingency has occurred which
materially and adversely affects the interbank markets, or (iii) the effective
cost to such Bank of funding a proposed Libor Rate Loan exceeds the Libor Rate
then (y) upon written notice thereof by the Agent or such Bank to the Borrowers,
the obligation of such Bank to make or continue a Loan of a type so affected or
to convert any type of Loan into a Loan of a type so affected shall terminate
and the Banks shall thereafter be obligated to make Prime Rate Loans whenever
any written notice requests any type of Loans so affected and (z) upon written
demand therefor by such Bank to the Borrowers, the Borrowers shall (i) forthwith
prepay in full all Loans of the type so affected then outstanding, together with
interest accrued thereon or (ii) request that such Bank, upon five (5) Business
Days' notice, convert all Loans of the type so affected then outstanding into
Loans of a type not so affected. If any such prepayment or conversion of any
Libor Rate Loan occurs on any day other than the last day of the applicable
Interest Period for such Loan, the Borrowers also shall pay to the Agent for the
ratable benefit of the Banks such additional amounts as set forth in Section
2.11(c).

                                      -21-
<PAGE>

     2.13 Payments. All payments to be made with respect to principal, interest,
fees or other amounts due from the Borrowers under this Agreement or under the
Notes are payable at 12:00 noon (Pittsburgh, Pennsylvania time), on the day when
due, without presentment, demand, protest or notice of any kind, all of which
are hereby expressly waived, and an action for the payments will accrue
immediately. All such payments must be made to the Agent at its Office in U.S.
Dollars and in funds immediately available at such Office, without setoff,
counterclaim or other deduction of any nature. The Agent may in its discretion
deduct such payments from the Borrowers' demand or deposit accounts with Agent
if not paid within five (5) days after the due date. All such payments shall be
applied at the option of the Agent and the Banks to accrued and unpaid interest,
outstanding principal and other sums due under this Agreement in such order as
the Agent and the Banks, in their sole discretion, shall elect. All such
payments shall be made absolutely net of, without deduction or offset, and
altogether free and clear of any and all present and future taxes, levies,
deductions, charges, and withholdings and all liabilities with respect thereto,
excluding income and franchise taxes imposed on the Banks under the Laws of the
United States or any state or political subdivision thereof. If the Borrowers
are compelled by Law to deduct any such taxes or levies (other than such
excluded taxes) or to make any such other deductions, charges, or withholdings
(collectively, the "Required Deductions"), the Borrowers will pay to the Agent
for the ratable benefit of the Banks an additional amount equal to the sum of
(i) the aggregate amount of all Required Deductions and (ii) the aggregate
amount of United States federal or state income taxes required to be paid by the
Banks in respect of such Required Deductions.

     2.14 Loan Account. The Agent will open and maintain on its books and
records, including computer records, in accordance with its customary
procedures, a loan account (the "Loan Account") for the Borrowers in which shall
be recorded the date and amount of each Loan made by the Banks and the date and
amount of each payment and prepayment in respect thereof. The Agent shall record
in the Loan Account the principal amount of the Loans owing to each Bank from
time to time. The Loan Account for the Borrowers will be presumptive evidence as
to the information contained therein. Any failure by the Agent to make any such
notation or record shall not affect the obligations of the Borrowers to the
Banks with respect to the Loans.

     2.15 Estoppel. As further consideration for the entry of the Banks into
this Agreement, the Borrowers hereby represent and warrant that they do not
presently have any claims or actions of any kind at Law or in equity against
Mellon arising out of or in any way relating to the Prior Loan Agreement or any
related documents with respect thereto, the transactions referenced in or
contemplated by this Agreement or any acts, transactions, or events that are or
were the subject matter of any other prior loans, agreements or guaranties
involving one or more of the Borrowers and a Bank.

                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

     The Borrowers represent and warrant to the Agent and the Banks that:

     3.01 Organization and Qualification. The Borrowers and their Subsidiaries
are corporations duly organized, validly existing and in good standing under
their respective jurisdictions of incorporation. Except to the extent that the
failure to be so qualified or licensed would not have a Material Adverse Effect,
the Borrowers and their Subsidiaries are duly qualified or licensed to do
business as a foreign corporation or partnership and are in good standing in all
jurisdictions in which the ownership of their properties or the nature of their
activities or both makes such qualification or licensing necessary.

     3.02 Power to Carry on Business; Licenses. Each Borrower and its
Subsidiaries have all requisite power and authority to own and operate its
properties and to carry on its business as now conducted and as presently
planned to be conducted. Except to the extent that the failure to have any such
license, permit, consent or approval would not have a Material Adverse Effect,
each Borrower and its Subsidiaries have all licenses, permits, consents and
governmental approvals or authorizations necessary to carry on its business as
now conducted and as presently planned to be conducted.

     3.03 Execution and Binding Effect. This Agreement, the Notes, and the other
Loan Documents to which the Borrowers are a party have been duly authorized by
all appropriate corporate action of each Borrower, have been duly and validly
executed and delivered by each Borrower which is a party thereto, and each such
document or agreement constitutes a legal, valid and binding obligation of such
Borrowers, enforceable against each such Borrower in accordance with its terms.

     3.06 Title to Property. Each Borrower and its Subsidiaries have good and
marketable title in fee simple to all real property and good and marketable
title to all other property purported to be owned by it, including that
reflected in the most recent balance sheet referred to in Section 3.07 of this
Agreement or submitted pursuant to Section 5.01(a) of this Agreement (except as

to Liens not forbidden by Section 6.01 of this Agreement.

     3.07 Financial Statements.

          (a) The Borrowers have delivered to the Agent and the Banks a
Consolidated balance sheet and related statements of income, retained earnings
and cash flow of the Borrowers and their Subsidiaries for the fiscal year ending
December 31, 2000, as audited by PricewaterhouseCoopers LLP without
qualification. Such financial statements (including the notes) present fairly
the Consolidated financial condition of the Borrowers and their Subsidiaries as
of the end of such fiscal period and the results of their operations and the
changes in financial position for the fiscal period then ended, all in
accordance with GAAP applied consistently with that of the preceding fiscal
year.

          (b) The Borrowers have delivered to the Agent and the Banks the
internally prepared Consolidated and consolidating balance sheets and related
statements of income and cash flow of the Borrowers and their Subsidiaries that
the Borrowers used to prepare the Borrowers' and their Subsidiaries' quarterly
financial results as of, and for the Fiscal Quarter ending, March 31, 2001, as
set forth in their 10-Q reports. Such financial statements provided by the
Borrowers present fairly the financial position of each Borrower and its

and their cash flow for the period then ended, all in conformity with sound
accounting principles, applied on a basis consistent with that of the preceding
fiscal periods.

permitted under Section 5.05 hereof, all material taxes, assessments, fees and
other governmental charges upon each Borrower and its Subsidiaries or upon any
of their properties, income, sales or franchises which are due and payable have
been paid. The reserves and provisions for taxes on the books of the Borrowers
and their Subsidiaries are adequate for all open years and for the current
fiscal period. No Borrower knows of any proposed additional material assessment

reserved against).

to the best knowledge of MBC, contemplated or threatened, action, suit or
proceeding by or before any Official Body against or affecting any Borrower or
its Subsidiaries, at Law or equity, which, if adversely decided, would have a
Material Adverse Effect.

     3.10 Compliance with Laws. To the best of MBC's knowledge, except as set
forth in Schedule 3.10 hereto, no Borrower nor any Subsidiary of a Borrower is
in violation of or

                                      -24-

subject to any material contingent liability on account of any Law which in the
aggregate would have a Material Adverse Effect.

     3.11 Pension Plans. Except as described in Schedule 3.11 to this Agreement,

no proceedings have been instituted to terminate any Plan, and there exists no
intent to terminate or institute proceedings to terminate any Plan where such
termination would have a Material Adverse Effect; (e) no withdrawal, either
complete or partial, has occurred or commenced with respect to any
multi-employer Plan, and there exists no intent to withdraw either completely or
partially from any multi-employer Plan; and (f) there has been no cessation of,
and there is no intent to cease, operations at a facility or facilities where
such cessation could reasonably be expected to result in a separation from
employment of more than 20% of the total number of employees who are

     3.12 Patents, Licenses, Franchises. The Borrowers and their Subsidiaries
own or possess the right to use all of the material patents, trademarks, service
marks, trade names, copyrights, licenses, franchises and permits and rights with
respect to the foregoing necessary to own and operate their properties and to
carry on their businesses as presently conducted and presently planned to be
conducted without conflict with the rights of others. There are no currently
pending or, to the best knowledge of MBC, threatened claims with respect to

Reauthorization Act of 1986, The Resource Conservation and Recovery Act of 1976,
as amended by the Hazardous and Solid Waste Amendments of 1984, The Clean Water
Act, The Toxic Substances Control Act and The Clean Air Act or any rule or

<PAGE>

by the EPA in the Federal Register for listing on such National Priorities List)
or identified under any corresponding state Law concerning cleanup of waste
disposal sites (a "State Superfund Law") except to the extent that the same has
been performed in compliance with all Environmental Laws, the non-compliance
with which in the aggregate would not have a Material Adverse Effect;

          (c) To the best knowledge of MBC, no predecessor of a Borrower has

of, or (ii) with a transporter for transport for the disposal or treatment of,
any Hazardous Substance, owned, used or possessed by the predecessor, except to
the extent that the same has been performed in compliance with all Environmental
Laws, the non-compliance with which in the aggregate would not have a Material
Adverse Effect;

          (d) Neither the Borrowers, their Subsidiaries nor any of their
Affiliates "owned" or "operated" any "facility" at the time any Hazardous
Substances were disposed of at such facility within the meaning of CERCLA, as
amended, or any State Superfund Law in violation of any applicable Environmental
Laws except to the extent that such violations would not have a Material Adverse
Effect.

Loans to repay Indebtedness of the Borrowers to Mellon under the Prior Loan
Agreement and for general corporate purposes, working capital and Acquisitions.

     3.15 Margin Stock. The Borrowers will make no borrowing under this
Agreement for the purpose of buying or carrying any "margin stock", as such term
is used in Regulation U and related regulations of the Board of Governors of the
Federal Reserve System, as amended from time to time. No Borrower owns any
"margin stock". No Borrower is engaged in the business of extending credit to
others for such purpose, and no part of the proceeds of any borrowing under this
Agreement will be used to purchase or carry any "margin stock" or to extend
credit to others for the purpose of purchasing or carrying any "margin stock".

     3.16 No Event of Default; Compliance with Material Agreements. No event has
occurred and is continuing and no condition exists which constitutes an Event of
Default or Potential Default. No Borrower nor any of its Subsidiaries is (i) in
violation of any term of any charter instrument or bylaw or (ii) in default
under any material agreement, lease or instrument to which it is a party or by
which it or any of its properties (owned or leased) may be subject or bound.

     3.19 Labor Controversies. There are no labor controversies pending or, to
the best knowledge of the officers and directors of MBC, threatened, against any
Borrower or any of its Subsidiaries which, if adversely determined, would have a
Material Adverse Effect.

     3.20 Solvency. After the making of the Loans, each Borrower (a) will be
able to pay its debts as they become due, (b) will have funds and capital
sufficient to carry on its business and all businesses in which it is about to

Subsidiaries to the Agent or any Bank pursuant to or in connection with this
Agreement is false or misleading (including by omission of information necessary
to make such representation, warranty or statement not misleading) in any manner
which would have a Material Adverse Effect.

however, if the Bank retains Persons not affiliated with the Bank to conduct any
such audit, the Bank shall use its reasonable best efforts to ensure that such
Persons are subject to appropriate non-disclosure and confidentiality
requirements for the benefit of the Borrowers. Provided that no Event of Default

written notice of any such visitation or inspection. Upon the occurrence and

Persons as the Agent or any of the Banks may designate (i) to visit and inspect

          (j) Notice of Proceedings. Promptly, and in any event within five (5)
Business Days, after becoming aware thereof, the Borrowers will give the Agent

information, and in such form, as the Agent or the Majority Banks may reasonably
request from time to time.

     5.02 Preservation of Existence and Franchises. Except as otherwise
permitted under this Agreement, the Borrowers will maintain their respective
corporate existences, rights and franchises in full force and effect in their
respective jurisdictions of incorporation. Except to the extent that the failure

their Subsidiaries will qualify and remain qualified as a foreign corporation in
each jurisdiction in which the ownership of their properties or the nature of
their activities or both makes such qualification necessary.

                                      -31-
<PAGE>

     5.03 Insurance. The Borrowers and their Subsidiaries will maintain with

properties and business and against such liabilities, casualties and
contingencies and of such types and in such amounts as is reasonably

other entities engaged in the same or similar business or having similar
properties similarly situated. The Borrowers agree to provide the Agent with
thirty (30) days advance notice of the termination of any such insurance
coverage.

     5.04 Maintenance of Properties. Except to the extent that the failure to do
so would not have a Material Adverse Effect, the Borrowers and their
Subsidiaries will maintain or cause to be maintained in good repair, working
order and condition (ordinary wear and tear excepted), the properties now or in
the future owned, leased or otherwise possessed by each of them and shall make
or cause to be made all needful and proper repairs, renewals, replacements and
improvements to the properties so that the business carried on in connection
with the properties may be properly and advantageously conducted at all times.

     5.05 Payment of Liabilities. The Borrowers and their Subsidiaries will pay
or discharge:

          (a) on or prior to the date on which penalties attach, all taxes,
assessments, fees and other governmental charges or levies imposed upon them or
any of their respective properties, income, sales or franchises other than those
contested with due diligence, in good faith, without the incurrence of any Lien
which would have a Material Adverse Effect and for which the Borrowers and their
Subsidiaries have established sufficient reserves on their books;

          (b) on or prior to the date when due, all lawful claims of
materialmen, mechanics, carriers, warehousemen, landlords and other like persons

adequate reserves on their books and for which the Borrowers and their
Subsidiaries have put in place adequate bonds or other security to cover the

the Borrowers and their Subsidiaries have established sufficient reserves on
their books.

     5.06 Financial Accounting Practices. The Borrowers and their Subsidiaries
will make and keep books, records and accounts which, in reasonable detail,
accurately and fairly reflect their respective transactions and dispositions of
assets and maintain a system of internal accounting controls sufficient to
provide reasonable assurances that (a) transactions are executed in accordance
with management's general or specific authorization, (b) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with GAAP and to maintain accountability for assets, (c) access to
assets is permitted only in accordance with management's general or specific
authorization and (d) the recorded accountability for assets is

                                      -32-
<PAGE>

compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

     5.07 Compliance with Laws. The Borrowers and their Subsidiaries shall

Agreement or shall consent to the appointment or to the taking of possession by
any such official of all or any substantial part of its property whether or not
any proceeding is instituted, shall dissolve, wind-up or liquidate itself or any
substantial part of its property, or shall take any action in furtherance of any
of the foregoing.

     7.02 Consequences of an Event of Default.

          (a) If an Event of Default specified in subsections (c) through (n) of
Section 7.01 of this Agreement occurs, the Agent and the Banks will be under no
further obligation to make Loans or issue Letters of Credit and may at the
option of the Majority Banks (i) demand the unpaid principal amount of the
Notes, interest accrued on the unpaid principal amount thereof and all other
amounts owing by the Borrowers under this Agreement, the Notes and the other
Loan Documents to be immediately due and payable without presentment, demand,
protest or further notice of any kind, all of which are expressly waived, and an
action for any amounts due shall accrue immediately; and (ii) require the
Borrowers to, and the Borrowers shall thereupon, deposit in a non-interest
bearing account with the Agent, as cash collateral for their obligations under
the Loan Documents, an amount equal to one hundred five percent (105%) of the
Letter of Credit Reserve, and the Borrowers hereby pledge to the Agent, and
grant to the Agent a security interest in, all such cash as security for such
obligations of the Borrowers.

          (b) If an Event of Default specified in subsections (a), (b), (o) or
(p) of Section 7.01 of this Agreement occurs and continues or exists, the Agent
and the Banks will be under no further obligation to make Loans or issue Letters
of Credit and the unpaid principal amount of the Notes, interest accrued thereon
and all other amounts owing by the Borrowers under this Agreement, the Notes and
the other Loan Documents shall automatically become immediately due and payable
without presentment, demand, protest or notice of any kind, all of which are
expressly waived, and an action for any amounts due shall accrue immediately.

     7.03 Set-Off. If the unpaid principal amount of the Notes, interest accrued
on the unpaid principal amount of the Notes or other amount owing by the
Borrowers under this Agreement, the Notes or the other Loan Documents shall have
become due and payable (at maturity, by acceleration or otherwise), each of the
Banks, any assignee of the Banks and the

                                      -42-
<PAGE>

holder of any participation in any Loan will each have the right, in addition to
all other rights and remedies available to it, without notice to the Borrowers,
to set-off against and to appropriate and apply to such due and payable amounts
any debt owing to, and any other funds held in any manner for the account of,
any Borrower by such Bank, by such assignee or by such holder including, without
limitation, all funds in all deposit accounts (whether time or demand, general
or special, provisionally credited or finally credited, or otherwise) now or in
the future maintained by any Borrower with such Bank, assignee or holder. The
Borrowers consent to and confirm the foregoing arrangements and confirm the
Banks' rights, such assignee's rights and such holder's rights of banker's lien
and set-off. Nothing in this Agreement will be deemed a waiver or prohibition of
or restriction on the Banks' rights, such assignee's rights or any such holder's
rights of banker's lien or set-off.

     7.04 Equalization. Each Bank agrees with the other Banks that if, at any
time, it shall obtain any Advantage over the other Banks or any thereof in
respect of the Indebtedness of the Borrowers to the Banks, it shall purchase
from the other Banks, for cash and at par, such additional participation in the
Indebtedness of the Borrowers to the Banks as shall be necessary to nullify the
Advantage. If any such Advantage resulting in the purchase of an additional
participation as aforesaid shall be recovered in whole or in part from the Bank
receiving the Advantage, each such purchase shall be rescinded and the purchase
price restored (but without interest unless the Bank receiving the Advantage is
required to pay interest on the Advantage to the Person recovering the Advantage
from such Bank) ratably to the extent of the recovery. Each Bank agrees with the
other Banks that if it, at any time, shall receive any payment for or on behalf
of the Borrowers on any Indebtedness of the Borrowers to that Bank by reason of
offset of any deposit or other Indebtedness of the Borrowers to the Banks, it
will apply such payment first to any and all Indebtedness of the Borrowers to
the Banks pursuant to this Agreement (including, without limitation, any
participation purchased or to be purchased pursuant to this Section or any other
Section of this Agreement). The Borrowers agree that any Bank so purchasing a
participation from the other Banks or any thereof pursuant to this Section may
exercise all of its rights of payment (including the right of setoff) with
respect to such participation as fully as if such Bank was a direct creditor of
the Borrowers in the amount of such participation.

     7.05 Other Remedies. The remedies in this Article VII are in addition to,
not in limitation of, any other right, power, privilege, or remedy, either in
Law, in equity, or otherwise, to which the Banks may be entitled. The Agent
shall exercise the rights under this Article VII and all other collection
efforts on behalf of the Banks and no Bank shall act independently with respect
thereto, except as otherwise specifically set forth in this Agreement.

                                  ARTICLE VIII

                     THE AGENT; ASSIGNMENTS; PARTICIPATIONS

     8.01 Appointment and Authorization; No Liability. The Banks authorize
Mellon and Mellon hereby agrees to act as agent for the Banks in respect of this
Agreement and the other Loan Documents upon the terms and conditions set forth
in this Agreement. Each Bank hereby irrevocably appoints and authorizes the
Agent to take such action as agent on its behalf and to exercise such powers
hereunder as are expressly delegated to the Agent by the

                                      -43-
<PAGE>

terms of this Agreement and any of the other Loan Documents, together with such
powers as are reasonably incidental thereto; provided that no duties or
responsibilities not expressly assumed herein or therein shall be implied to
have been assumed by the Agent. The relationship between the Agent and the Banks
is and shall be that of agent and principal only, and nothing contained in this
Agreement or any of the other Loan Documents shall be construed to constitute
the Agent as a trustee for any Bank. Neither the Agent nor any of its
shareholders, directors, officers, attorneys or employees nor any other Person
assisting them in their duties nor any agent or employee thereof, shall (a) be
liable for any waiver, consent or approval given or action taken or omitted to
be taken by it or them hereunder or under any of the Loan Documents or in
connection herewith or therewith or be responsible for the consequences of any
oversight or error of judgment whatsoever, or (b) be liable to the Borrowers for
consequential damages resulting from any breach of contract, tort or other wrong
in connection with the negotiation, documentation, administration or collection
of the Loans or any of the Loan Documents, except with respect to (a) and (b)
hereof, to the extent of its or their willful misconduct or gross negligence as
finally determined by a court of competent jurisdiction.

     8.02 Employees and Agents. The Agent may exercise its powers and execute
its duties by or through employees or agents and shall be entitled to take, and
to rely on, advice of counsel concerning all matters pertaining to its rights
and duties under this Agreement and the other Loan Documents and shall not be
liable for action taken or suffered in good faith by it in accordance with the
opinion of such counsel. The Agent may utilize the services of such Persons as
the Agent in its sole discretion may determine, and all reasonable fees and
expenses of any such Persons shall be paid by the Borrowers and if not paid by
the Borrowers shall be paid by the Banks based upon their respective Commitment
Percentages.

     8.03 No Representations; Each Bank's Independent Investigation. The Agent
shall not be responsible for (a) the execution, validity or enforceability of
this Agreement, the Notes, any of the other Loan Documents or any instrument at
any time constituting, or intended to constitute, collateral security for the
Notes, (b) the value of any such collateral security, (c) the validity,
enforceability or collectibility of any such amounts owing with respect to the
Notes, or (d) any recitals or statements, warranties or representations made
herein or in any of the other Loan Documents or in any certificate or instrument
hereafter furnished to it by or on behalf of the Borrowers. The Agent shall not
be bound (a) to ascertain or inquire as to the performance or observance of any
of the terms, conditions, covenants or agreements herein or in any instrument at
any time constituting, or intended to constitute, collateral security for the
Indebtedness evidenced by the Notes or (b) to ascertain whether any notice,
consent, waiver or request delivered to it by the Borrowers or any holder of any
of the Notes shall have been duly authorized or is true, accurate and complete.
The Agent has not made nor does it now make any representations or warranties,
express or implied, nor does it assume any liability to the Banks with respect
to the creditworthiness, financial condition or any other condition of the
Borrowers or with respect to the statements contained in any information
memorandum furnished in connection herewith or in any other oral or written
communication between the Agent and such Bank. Each Bank acknowledges that it
has, independently without reliance upon the Agent or any other Bank, and based
upon such information and documents as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and agrees that the
Agent has no duty or responsibility, either initially or on a continuing basis,
to provide any Bank with

                                      -44-
<PAGE>

any credit or other information with respect thereto (other than such notices
as may be expressly required to be given by the Agent to the Banks hereunder).

     8.04 Payments to Banks.

          (a) As between the Agent and the Borrowers, a payment by the Borrowers
to the Agent hereunder or any of the other Loan Documents for the account of any
Bank shall constitute a payment to such Bank. The Agent agrees to promptly, but
in any event not later than the end of the following Business Day, distribute to
each Bank such Bank's Pro Rata Share of payments received by the Agent for the
account of the Banks in immediately available funds.

          (b) If in the opinion of the Agent the distribution of any amount
received by it in such capacity hereunder, under the Notes or under any of the
other Loan Documents, could reasonably be expected to involve it in liability,
it may refrain from making distribution until its right to make distribution
shall have been adjudicated by a court of competent jurisdiction. If a court of
competent jurisdiction shall adjudge that any amount received by the Agent for
the account of the Banks is to be distributed, the Agent shall distribute to
each Bank such Bank's Pro Rata Share of the amount so adjudged to be distributed
or in such manner as shall be determined by such court, together with interest
thereon, in respect of each day during the period commencing on the date such
amount was made available to the Agent and ending on the date the Agent
distributes such amount, at a rate per annum equal to the interest rate earned
by the Agent on such amount during such period. If a court of competent
jurisdiction shall adjudge that any amount received and distributed by the Agent
is to be repaid, each Person to whom any such distribution shall have been made
shall either repay to the Agent its proportionate share of the amount so
adjudged to be repaid or shall pay over the same in such manner and to such
Persons as shall be determined by such court.

          (c) Notwithstanding anything to the contrary contained in this
Agreement or any of the other Loan Documents, any Bank that fails (i) to make
available to the Agent its Pro Rata Share of any Loan that the Agent made on its
behalf or (ii) to comply with the provisions of Section 7.04 with respect to it
obtaining an Advantage, in each case as, when and to the full extent required by
the provisions of this Agreement, shall be deemed delinquent and shall not be
entitled to vote on any matters until such time as such delinquency is cured.
Such Bank shall be deemed to have assigned any and all payments due it from the
Borrowers, whether on account of outstanding Loans, interest, fees or otherwise,
to the remaining Banks for application to, and reduction of, their respective
Pro Rata Shares of all outstanding Loans. Such Bank hereby authorizes the Agent
to distribute such payments to the other Banks in proportion to their respective
Pro Rata Shares of all outstanding Loans. Such Bank shall be deemed to have
satisfied in full a delinquency when and if the Banks' respective Pro Rata
Shares of all outstanding Loans have returned to those in effect immediately
prior to such delinquency and without giving effect to the nonpayment causing
such delinquency.

     8.05 Note Holders. The Agent may treat the payee of any Note as the holder
thereof until written notice of transfer shall have been filed with it signed by
such payee and in form satisfactory to the Agent.

                                      -45-
<PAGE>

     8.06 Documents. The Agent shall not be under any duty to examine into or
pass upon the validity, effectiveness, genuineness or value of any Loan
Documents or any other document furnished pursuant hereto or in connection
herewith or the value of any collateral obtained hereunder, and the Agent shall
be entitled to assume that the same are valid, effective and genuine and what
they purport to be.

     8.07 Agents and Affiliates. With respect to the Loans, the Agent shall have
the same rights and powers hereunder as any other Bank and may exercise the same
as though it were not the agent, and the Agent and its affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
the Borrowers or any of their Affiliates.

     8.08 Indemnification of Agent. The Banks ratably agree to indemnify and
hold harmless the Agent from and against any and 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 Agent in its capacity as agent in any way relating to
or arising out of this Agreement or any Loan Document or any action taken or
omitted by the Agent with respect to this Agreement or any Loan Document,
provided that no Bank shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including attorney fees) or disbursements resulting from the Agent's
gross negligence or willful misconduct as finally determined by a court of
competent jurisdiction. The obligations of the Banks under this Section 8.08
shall survive the payment in full of all amounts due pursuant to this Agreement
or any other Loan Document and the termination of this Agreement.

     8.09 Successor Agent. The Agent may resign as agent hereunder by giving not
fewer than thirty (30) days' prior written notice to the Borrowers and the
Banks. If the Agent shall resign under this Agreement, then either (a) the
Majority Banks shall appoint from among the Banks a successor agent for the
Banks or (b) if a successor agent shall not be so appointed and approved within
the thirty (30) day period following the Agent's notice to the Banks of its
resignation, then the Agent shall appoint a successor agent who shall serve as
agent until such time as the Majority Banks appoint a successor agent pursuant
to clause (a). Upon its appointment, such successor agent shall succeed to the
rights, powers and duties as agent, and the term "Agent" shall mean such
successor effective upon its appointment, and the former agent's rights, powers
and duties as agent shall be terminated without any other or further act or deed
on the part of such former agent or any of the parties to this Agreement.

     8.10 Knowledge of Default. It is expressly understood and agreed that the
Agent shall be entitled to assume that no Event of Default or Potential Default
has occurred and is continuing unless the Agent has been notified by a Bank or
the Borrowers in writing that such Bank or the Borrowers consider that an Event
of Default or Potential Default has occurred and is continuing and specifying
the nature thereof.

     8.11 Action by Agent. So long as the Agent shall be entitled, pursuant to
Section 8.10 hereof, to assume that no Event of Default or Potential Default
shall have occurred and be continuing, the Agent shall be entitled to use its
discretion with respect to exercising or refraining from exercising any rights
which may be vested in it by, or with respect to taking or refraining from
taking any action or actions which it may be able to take under or in respect
of,

                                      -46-
<PAGE>

this Agreement. The Agent shall incur no liability under or in respect of this
Agreement by acting upon any notice, certificate, warranty or other paper or
instrument believed by it to be genuine or authentic or to be signed by the
proper party or parties, or with respect to anything which it may do or refrain
from doing in the reasonable exercise of its judgment.

     8.12 Notification of Potential Defaults and Events of Defaults. Each Bank
hereby agrees that, upon learning of the existence of a Potential Default or
Event of Default, it shall promptly notify the Agent thereof. In the event that
the Agent receives notice of an Event of Default or Potential Default, the Agent
shall promptly notify all of the Banks and shall take such action and assert
such rights under this Agreement as the Majority Banks shall direct and the
Agent shall promptly inform the Banks in writing of the action taken. The Agent
may take such action and assert such rights as it deems to be advisable, in its
discretion, for the protection of the interests of the holders of the Notes.

     8.13 Declaration of Invalidation. Each Bank agrees that, to the extent that
any payments received by any Bank from the Borrowers or otherwise on account of
the Loans are subsequently invalidated, declared to be fraudulent or
preferential, set aside or judicially required to be repaid to a
debtor-in-possession, trustee, receiver, custodian or any other Person in
connection with any proceeding referred to in Section 7.01(o) hereof or any
similar cause of action ("Preference"), then, to the extent of such Preference,
each Bank shall, upon demand, reimburse the Bank subject to such Preference in
the amount necessary to cause each Bank to be affected by such Preference in
proportion to its Pro Rata Share of the Loans.

     8.14 Pro Rata Portion, Pari Passu and Equal. The Pro Rata Share of each
Bank in the Loans and the Letters of Credit shall be pari passu and equal with
the Pro Rata Share of each other Bank and no Bank shall have priority over the
other.

     8.15 Cooperation. Each Bank agrees that it shall cooperate in good faith
and in a commercially reasonable manner with each other Bank and take whatever
reasonable actions (at its own expense) are necessary to implement decisions
made in accordance with this Agreement and with each of the other Loan Documents
relating thereto.

     8.16 Obligations Several. The obligations of the Banks hereunder are
several and not joint. Nothing contained in this Agreement, and no action taken
by the Agent or the Banks pursuant hereto, shall be deemed to constitute a
partnership, association, joint venture or other entity between any of the
Banks. No default by any Bank hereunder shall excuse any Bank from any
obligation under this Agreement, but no Bank shall have or acquire any
additional obligation of any kind by reason of such default. The relationship
among the Borrowers and the Banks with respect to the Loan Documents and any
other document executed in connection therewith is and shall be solely that of
debtor and creditors, respectively, and neither the Agent nor any Bank has any
fiduciary obligation toward the Borrowers with respect to any such documents or
the transactions contemplated thereby.

                                      -47-

     8.17 Bank Assignments/Participations.

     A. Assignment/Transfer of Commitments.

Each Bank shall have the right at any time or times to assign or transfer to
another Eligible Assignee, without recourse, all or a portion of (a) that Bank's
Commitment, (b) all Loans made by that Bank, (c) that Bank's Notes, and (d) that
Bank's participation purchased pursuant to Section 7.04; provided, however, in
each such case, that the transferor and the transferee shall have complied with
the following requirements:

               (i) Prior Consent of Agent. No transfer may be consummated
pursuant to this Section 8.17(A) (including, without limitation, a transfer from
one Bank to another Bank) without the prior written consent of the Agent (other
than a transfer by any Bank to any affiliate of such Bank or a transfer
occurring during the existence of an Event of Default or Potential Default),
which consent of the Agent shall not be unreasonably withheld, delayed or
conditioned.

               (ii) Prior Consent of Borrowers. No transfer may be consummated
pursuant to this Section 8.17 (including, without limitation, a transfer from
one Bank to another Bank) without the prior written consent of the Borrowers
(other than a transfer by any Bank to any affiliate of such Bank or a transfer
occurring during the existence of an Event of Default or Potential Default),
which consent of the Borrowers shall not be unreasonably withheld, delayed or
conditioned.

               (iii) Minimum Amount. No transfer may be consummated pursuant to
this Section 8.17(A) (including, without limitation, a transfer from one Bank to
another Bank other than a transfer by any Bank to an affiliate of such Bank) in
an aggregate amount less than (a) Five Million and 00/100 Dollars
($5,000,000.00) or (b) if such Bank's Commitment is at any time less than Five
Million and 00/100 Dollars ($5,000,000.00), the entire amount of such Bank's
Commitment.

               (iv) Agreement; Transfer Fee. Unless the transfer shall be to an
affiliate of the transferor or the transfer shall be due to merger of the
transferor or for regulatory purposes, the transferor (A) shall remit to the
Agent, for its own account, an administrative fee of Three Thousand Five Hundred
and 00/100 Dollars ($3,500.00) and (B) shall cause the transferee to execute and
deliver to the Borrowers, the Agent and each Bank (1) an Assignment Agreement,
in the form of Exhibit "C" attached hereto and made a part hereof (an
"Assignment Agreement') together with the consents and releases and the
Administrative Questionnaire referenced therein, and (2) such additional
amendments, assurances and other writings as the Agent may reasonably require.

               (v) Notes. Upon its receipt of an Assignment Agreement executed
by the parties to such Assignment, together with each Note subject to such
Assignment Agreement, the Agent shall (a) record the information contained
therein in the Register, and (b) give prompt notice thereof to the Borrowers and
the other Banks. Within five (5) Business Days after receipt of such notice, the
Borrowers, at their own expense, shall execute and deliver (A) to the Agent, the
transferor and the transferee, any consent or release (of

                                      -48-
<PAGE>

all or a portion of the obligations of the transferor) to be delivered in
connection with the Assignment Agreement, and (B) to the transferee and, if
applicable, the transferor, the appropriate Notes. Upon delivery of the new
Notes, the transferor's Notes shall be promptly returned to the Borrowers marked
"replaced".

               (vi) Parties. Upon satisfaction of the requirements of this
Section 8.17, including the payment of the fee and the delivery of the documents
set forth in Section 8.17(A) (iv), (A) the transferee shall become and
thereafter be deemed to be a "Bank" for the purposes of this Agreement, (B) if
the transferor transfers all of its interest, the transferor shall cease to be
and thereafter shall no longer be deemed to be a "Bank" and shall have no
further rights or obligations under or in connection herewith, and (C) the
signature pages hereof and Schedule 1 hereto shall be automatically amended,
without further action, to reflect the result of any such transfer.

               (vii) The Register. The Agent shall maintain a copy of each
Assignment Agreement delivered to it and a register or similar list (the
"Register") for the recordation of the names and addresses of the Banks and the
Commitment Percentages of, and principal amount of the Loans owing to, each Bank
from time to time. The entries in the Register shall be conclusive, in the
absence of manifest error, with respect to such information, and the Borrowers,
the Agent and the Banks may treat each financial institution whose name is
recorded in the Register as the owner of the Loan recorded therein for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrowers or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

               (viii) Certain Representations and Warranties; Limitations;
Covenants. By executing and delivering an Assignment Agreement, the parties to
the Assignment thereunder confirm to and agree with each other and the other
parties hereto as follows:

                    (a) Other than the representation and warranty that it is
the legal and beneficial owner of the interest being assigned thereby free and
clear of any adverse claim, the assigning Bank makes no representation and
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement, the other Loan Documents or any other instrument or
document furnished pursuant hereto;

                    (b) The assigning Bank makes no representation or warranty
and assumes no responsibility of the financial condition of the Borrowers or any
other Person primarily or secondarily liable in respect of any of the
Indebtedness of the Borrowers to the Banks, or the performance or observance by
the Borrowers or any other Person primarily or secondarily liable in respect of
any of the Indebtedness of the Borrowers to the Banks or any of their
obligations under this Agreement or any of the other Loan Documents or any other
instrument or document furnished pursuant hereto or thereto;

                    (c) Such assignee confirms that it has received a copy of
this Agreement, together with copies of the most recent financial statements
referred to in

                                      -49-
<PAGE>

Section 5.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into the
Assignment Agreement;

                    (d) Such assignee will, independently and without reliance
upon the assigning Bank, the Agent or any other Bank and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agreement;

                    (e) Such assignee represents and warrants that it is an
Eligible Assignee;

                    (f) Such assignee appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers under this
Agreement and the other Loan Documents as are delegated to the Agent by the
terms hereof or thereof, together with such powers as are reasonably incidental
thereto;

                    (g) Such assignee agrees that it will perform in accordance
with their terms all of the obligations that by the terms of this Agreement are
required to be performed by it as a Bank; and

                    (h) Such assignee represents and warrants that it is legally
authorized to enter into such Assignment Agreement.

     B. Participations.

     Each Bank shall have the right at any time or times, without the consent of
any other party, to sell one or more participations or sub-participations to one
or more financial institutions, in all or any part of (a) that Bank's
Commitment, (b) that Bank's Commitment Percentage, (c) any Loan made by that
Bank, (d) any Note delivered to that Bank pursuant to this Agreement and (e)
that Bank's participations, if any, purchased pursuant to Section 7.04 or this
Section 8.17(B).

               (i) Rights Reserved. In the event any Bank shall sell any
participation or sub-participation, that Bank shall, as between itself and the
purchaser, retain all of its rights (including, without limitation, rights to
enforce against the Borrowers the Loan Documents and any and all other documents
in connection therewith) and duties pursuant to the Loan Documents and any and
all other documents in connection therewith, including, without limitation, that
Bank's right to approve any waiver, consent or amendment pursuant to Section
9.02; provided, however, that (a) any such participation shall be in a minimum
amount of Five Million and 00/100 Dollars ($5,000,000.00) and (b) the holder of
any such participation shall not be entitled to require such Bank to take any
action hereunder except action directly affecting (i) any reduction in the
principal amount or an interest rate on any Loan in which such holder
participates; (ii) any extension of the Expiry Date or the date fixed for any
payment of interest or principal payable with respect to any Loan in which such
holder participates; and (iii) any reduction in the amount of any fees payable
hereunder with respect to any Loan in which such holder participates. The
Borrowers hereby acknowledge and agree that the participant under

                                      -50-
<PAGE>

each participation shall for purposes of Sections 2.11(b), 2.12, 7.03 and 9.16
be considered to be a "Bank". Except as otherwise set forth herein, no
participant or sub-participant shall have any rights or obligations hereunder,
and the Borrowers and the Agent shall continue to deal with the Banks as if no
participation or sub-participation had occurred. The Agent shall continue to
distribute payments as if no participation or sub-participation had been sold.

               (ii) No Delegation. No participation or sub-participation shall
operate as a delegation of any duty of the seller thereof. Under no
circumstances shall any participation or sub-participation be deemed a novation
in respect of all or any part of the seller's obligations pursuant to this
Agreement.

          C. Pledge by Banks. Notwithstanding the provisions of this Section
8.17, any Bank may at any time pledge all or any portion of its interest and
rights under this Agreement (including all or any portion of its Notes) to any
of the federal reserve banks organized under Section 4 of the Federal Reserve
Act, 12 U.S.C. Section 341. No such pledge or the enforcement thereof shall

                                  MISCELLANEOUS

     9.01 Business Days. Except as otherwise provided in this Agreement,
whenever any payment or action to be made or taken under this Agreement, or
under the Notes or under any of the other Loan Documents is stated to be due on
a day which is not a Business Day, such payment or action will be made or taken
on the next following Business Day and such extension of time will be included
in computing interest or fees, if any, in connection with such payment or
action.

     9.02 Amendments and Waivers. No amendment, modification, termination, or
waiver of any provision of this Agreement or any Loan Document, nor consent to
any variance therefrom, shall be effective unless the same shall be in writing
and signed by the Majority Banks and the Borrowers and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose given. Notwithstanding anything contained herein to the contrary,
unanimous consent of the Banks shall be required with respect to (a) any
increase in the Commitments hereunder, (b) the extension of the Expiry Date, the
payment date of interest or principal hereunder, or the payment of commitment or
other fees or amounts payable hereunder, (c) any reduction in the rate of
interest on the Notes, or in any amount of principal or interest due on any
Note, or the payment of commitment or other fees hereunder or any change in the
manner of pro rata application of any payments made by the Borrowers to the
Banks hereunder, (d) any change in any percentage voting requirement, voting
rights or the definition of Majority Banks in this Agreement, or (e) any
amendment to this Section 9.02, 9.11 or Section 7.04 hereof. Notice of
amendments or consents ratified by the Banks hereunder shall be immediately
forwarded by the Agent to all Banks. Each Bank or other holder of a Note shall
be bound by any amendment, waiver or consent obtained as authorized by this
Section, regardless of its failure to agree thereto. In the case of any such
waiver or consent relating to any provision of this Agreement, any Event of
Default or Potential Default so waived or consented to will be deemed to be
cured and not

                                      -51-
<PAGE>

continuing, but no such waiver or consent will extend to any other or
subsequent Event of Default or Potential Default or impair any right consequent
to any other or subsequent Event of Default or Potential Default or impair any
right consequent thereto.

     9.03 No Implied Waiver: Cumulative Remedies. No course of dealing and no
delay or failure of the Agent or the Banks in exercising any right, power or
privilege under this Agreement, the Notes or any other Loan Document will affect
any other or future exercise of any such right, power or privilege or exercise
of any other right, power or privilege except as and to the extent that the
assertion of any such right, power or privilege shall be barred by an applicable
statute of limitations; nor shall any single or partial exercise of any such
right, power or privilege or any abandonment or discontinuance of steps to
enforce such a right, power or privilege preclude any further exercise of such
right, power or privilege or of any other right, power or privilege. The rights
and remedies of the Agent and the Banks under this Agreement, the Notes or any
other Loan Document are cumulative and not exclusive of any rights or remedies
which the Banks would otherwise have.

     9.04 Notices. All notices, requests, demands, directions and other
communications (collectively, "Notices") under the provisions of this Agreement
or the Notes must be in writing (including telexed or telecopied communication)

     9.05 Expenses; Taxes; Attorneys Fees. The Borrowers agree to pay or cause
to be paid and to save the Agent and the Banks harmless against liability for
the payment of all reasonable out-of-pocket expenses, including, but not limited
to reasonable fees and expenses of counsel and paralegals for the Agent and the
Banks, incurred by the Agent and the Banks from time to time (i) arising in
connection with the preparation, execution, delivery and performance of this
Agreement, the Notes and the other Loan Documents, (ii) relating to any
requested amendments, waivers or consents to this Agreement, the Notes or any of
the other Loan Documents and (iii) arising in connection with the Agent's and
the Banks' enforcement or preservation of rights under this Agreement, the Notes
or any of the other Loan Documents including, but not limited to, such expenses
as may be incurred by the Agent and the Banks in the collection of the
outstanding principal amount of the Loans. The Borrowers agree to pay all stamp,
document, transfer, recording or filing taxes or fees and similar impositions
now or in the future determined by the Agent and the Banks to be payable in
connection with this Agreement, the Notes or any other Loan Document. The
Borrowers agree to save the Agent and the Banks harmless from and against any
and all present or future claims, liabilities or losses with respect to or
resulting from any omission to pay or delay in paying any such taxes, fees or

at law or suit in equity in relation to this Agreement, the Notes or the other
Loan Documents, the Borrowers will pay, in addition to all other sums which the
Borrowers may be required to pay, a reasonable sum for attorneys and paralegals
fees incurred by the Agent and the Banks or the holder of the Notes in
connection with such action or suit. All payments due from the Borrowers under
this Section will be added to and become part of the Loans until paid in full.

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

     9.07 Governing Law: Consent to Jurisdiction. This Agreement will be deemed
to be a contract under the Laws of the Commonwealth of Pennsylvania and for all
purposes will

                                      -53-
<PAGE>

be governed by and construed and enforced in accordance with the substantive
Laws, and not the laws of conflicts, of said Commonwealth. The Borrowers consent
to the exclusive jurisdiction and venue of the federal and state courts located
in Allegheny County, Pennsylvania, in any action on, relating to or mentioning
this Agreement, the Notes, the other Loan Documents, or any one or more of them.

     9.08 Prior Understandings. This Agreement, the Notes and the other Loan
Documents supersede all prior understandings and agreements, whether written or
oral, among the parties relating to the transactions provided for in this
Agreement, the Notes and the other Loan Documents.

     9.09 Duration: Survival. All representations and warranties of the
Borrowers contained in this Agreement or made in connection with this Agreement
or any of the other Loan Documents shall survive the making of and will not be
waived by the execution and delivery of this Agreement, the Notes or the other
Loan Documents, by any investigation by the Agent or any Bank, or the making of
any Loan. Notwithstanding termination of this Agreement or an Event of Default,
all covenants and agreements of the Borrowers will continue in full force and
effect from and after the date of this Agreement so long as the Borrowers may
borrow under this Agreement and until payment in full of the Notes, interest
thereon, and all fees and other obligations of the Borrowers under this
Agreement or the Notes. Without limitation, it is understood that all
obligations of the Borrowers to make payments to or indemnify the Agent and the
Banks will survive the payment in full of the Notes and of all other obligations
of the Borrowers under this Agreement, the Notes and the other Loan Documents.

     9.10 Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties to this Agreement on separate
counterparts each of which, when so executed, will be deemed an original, but
all such counterparts will constitute but one and the same instrument.

     9.11 Successors and Assigns. This Agreement will be binding upon and inure
to the benefit of the Agent, the Banks, the Borrowers and their successors and
assigns, except that the Borrowers may not assign or transfer any of its rights
under this Agreement without the prior written consent of the Banks.

     9.12 No Third Party Beneficiaries. The rights and benefits of this
Agreement and the other Loan Documents are not intended to, and shall not, inure
to the benefit of any third party.

     9.13 Exhibits. All exhibits and schedules attached to this Agreement are
incorporated and made a part of this Agreement.

     9.14 Headings. The section headings contained in this Agreement are for
convenience only and do not limit or define or affect the construction or
interpretation of this Agreement in any respect.

     9.15 Limitation of Liability. To the fullest extent permitted by Law, no
claim may be made by the Borrowers against the Agent or the Banks, or by the
Agent or the Banks against the Borrowers, or by the Borrowers, the Agent or the
Banks against any affiliate,

                                      -54-
<PAGE>

director, officer, employee, attorney or agent of the other for any special,
incidental, indirect, consequential or punitive damages in respect of any claim
arising from or related to this Agreement or any other Loan Document or any
statement, course of conduct, act, omission or event occurring in connection
herewith or therewith (whether for breach of contract, tort or any other theory
of liability). The Borrowers, the Agent and the Banks hereby waive, release and
agree not to sue upon any claim for any such damages, whether such claim
presently exists or arises hereafter and whether or not such claim is known or
suspected to exist in its favor. This Section 9.15 shall not limit any rights of
the Borrowers, the Agent or the Banks arising solely out of gross negligence or
willful misconduct.

     9.16 Indemnities. In addition to the payment of expenses pursuant to
Section 9.05 hereof, the Borrowers agree to indemnify, pay and hold the Agent
and each Bank and their officers, directors and attorneys (collectively, called
the "Indemnitees"), harmless from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, claims,
costs, expenses and disbursements of any kind or nature whatsoever (including
the reasonable fees and disbursements of counsel for such Indemnitees in
connection with any investigative, administrative or judicial proceeding
commenced or threatened, whether or not such Indemnitee shall be designated a
party thereto) that may be imposed on, incurred by or asserted against that
Indemnitee, in any matter arising from the occurrence of an Event of Default
hereunder or under the other Loan Documents, or the exercise of any right or
remedy hereunder or under the other Loan Documents (the "Indemnified
Liabilities"); provided, however, that the Borrowers shall have no obligation to
an Indemnitee hereunder with respect to Indemnified Liabilities arising from the
gross negligence or willful misconduct of that Indemnitee.
