                            REVOLVING CREDIT FACILITY

                  2.01. Revolving Credit Commitments. Subject to the terms and
conditions hereof and relying upon the representations and warranties herein set
forth, each Lender severally agrees to make revolving credit loans (the
"Revolving Credit Loans") to the Borrower at any time or from time to time on or
after the date hereof to, but not including, the Expiration Date, provided that
the aggregate principal amount of each Lender's Revolving Credit Loans
outstanding hereunder to the Borrower shall not exceed at any one time such
Lender's Ratable Share of the aggregate Revolving Credit Commitments or the
Borrowing Base, whichever is less, minus such Lender's Ratable Share of the sum
of (i) the Swingline Loans outstanding, (ii) the aggregate Stated Amount of
outstanding Letters of Credit and (iii) the aggregate amount of Unreimbursed L/C
Draws. Within such limits of time and amount and subject to the other provisions
of this Agreement, the Borrower may borrow, repay and reborrow pursuant to this
Section 2.01. The aggregate amount of the Revolving Credit Commitments on the
Closing Date is $100,000,000. All Revolving Credit Commitments shall expire on
the Expiration Date; and all Revolving Credit Loans outstanding on the
Expiration Date shall become due and payable in full on such date.

                  2.02. Nature of Lenders' Obligations with Respect to Revolving
Credit Loans. Each Lender shall be obligated to participate in each request for
Revolving Credit Loans pursuant to Section 2.05 hereof in accordance with its
Ratable Share. The aggregate principal amount of each Lender's Revolving Credit
Loans outstanding hereunder to the Borrower at any time shall never exceed such
Lender's Ratable Share of the aggregate Revolving Credit Commitments or the
Borrowing Base, whichever is less, minus such Lender's Ratable Share of the sum
of (i) Swingline Loans outstanding, (ii) the aggregate Stated Amount of
outstanding Letters of Credit and (iii) the aggregate amount of Unreimbursed L/C
Draws. The obligations of each Lender hereunder are several. The failure of any
Lender to perform its obligations hereunder shall not affect the obligations of
the Borrower, or any other Lender, to any other party

                                     - 23 -
<PAGE>

nor shall the Borrower, or any other Lender, be liable for the failure of such
Lender to perform its obligations hereunder. The Lenders shall have no
obligation to make Revolving Credit Loans hereunder on or after the relevant
Expiration Date.

                  2.03. Fees

                           (a) Facility Fee. Accruing from the Closing Date
until the Expiration Date, the Borrower agrees to pay to the Agent for the
account of each Lender as consideration for such Lender's Revolving Credit
Commitment hereunder a Facility Fee determined by multiplying the relevant
Applicable Facility Fee by such Lender's Revolving Credit Commitment. The
Facility Fee from the Closing Date until June 30, 2002 shall be 37.5 basis
points. The Facility Fee shall be payable (i) quarterly in arrears on the last
day of each Fiscal Quarter, (ii) upon the relevant Expiration Date, and (iii)
upon acceleration of the Notes, all computed at the opening of business and on
the basis of a year of 365 or 366 days, as the case may be, and actual days
elapsed.

                           (b) Closing Fee. The Borrower agrees to pay on the
Closing Date, to the Agent for the account of each Lender as consideration for
such Lender's Revolving Credit Commitment hereunder a Closing Fee determined by
multiplying such Lender's Revolving Credit Commitment hereunder by 50 basis
points.

                           (c) Agent's and Arranger's Fee. The Borrower agrees
to pay to the Agent for its account the agent's fee and to PNC Capital Markets,
Inc. for its account the arrangement fee, all at the times and as more fully set
forth in the Agent's Letter.

                           (d) Applicable Facility Fee. For purposes of this
Agreement, the term "Applicable Facility Fee" shall mean the rate per annum set
forth in the chart below which corresponds to the range of ratios in which the
Borrower's Consolidated Total Indebtedness to Consolidated EBITDA Ratio, as at
the end of the preceding fiscal quarter, falls:

                  Consolidated Total Indebtedness             Applicable
                   to Consolidated EBITDA Ratio               Facility Fee
                  -------------------------------             ------------
                  Less than or equal to 2.0 to 1.0               0.375%

                  Greater than 2.0 to 1.0                        0.50%

All such adjustments shall be determined as of the date the Borrower's quarterly
financial statements and Compliance Certificate are required to be delivered to
the Lenders pursuant to items (i) and (iii) of Section 6.02.

                  2.04. Voluntary Reduction of Revolving Credit Commitment
Subject to the provisions of Section 2.09 hereof, at any time and from time to
time upon at least five (5) Business Days' prior written notice to the Agent,
the Borrower may terminate, in whole or in part, without penalty, the then
unused portion of the Revolving Credit Commitments, thereby causing a
corresponding abatement of the Facility Fee. Each such reduction shall be in a

                                     - 24 -
<PAGE>

minimum principal amount of $5,000,000 or, if in excess of $5,000,000, in
integral multiples of $1,000,000. The Facility Fee shall cease to accrue with
respect to the Revolving Credit Commitments so terminated five (5) Business Days
after receipt of such notice. Notice of termination once given shall be
irrevocable and the portion of the Revolving Credit Commitments so terminated
shall not be available for borrowing once such notice has been given under the
terms hereof. The Agent shall promptly notify each Lender of its Ratable Share
of such terminated unused portion and the date of each such termination.

                  2.05. Revolving Credit Loan Requests. Except as otherwise
provided herein, the Borrower may from time to time prior to the relevant
Expiration Date request the Lenders to make Revolving Credit Loans to the
Borrower by the delivery to the Agent, not later than 10:00 a.m. (Pittsburgh,
Pennsylvania time) (i) three (3) Business Days prior to the proposed Borrowing
Date with respect to the making of Revolving Credit Loans to which the Euro-Rate
Option applies for any Revolving Credit Loans; and (ii) on the Business Day of
the proposed Borrowing Date with respect to the making of a Revolving Credit
Loan to which the Base Rate Option applies of a duly completed request therefor
substantially in the form of Exhibit "E" hereto or a request by telephone
immediately confirmed in writing by letter or facsimile in such form (each, a
"Loan Request"), it being understood that the Agent may rely on the authority of
any person making such a telephonic request without the necessity of receipt of
such written confirmation. Each Loan Request shall be irrevocable and shall
specify (i) the proposed Borrowing Date; (ii) the aggregate amount of the
proposed Revolving Credit Loans to be made on such Borrowing Date, which amount,
as to Base Rate Portions, shall be in integral multiples of $500,000 and not
less than $1,000,000 and, as to Euro-Rate Portions, shall be in integral
multiples of $1,000,000 and not less than $5,000,000; (iii) subject to Section
2.08(d), whether the Euro-Rate Option or the Base Rate Option shall apply to the
proposed Revolving Credit Loans to be made on such Borrowing Date; and (iv) in
the case of Revolving Credit Loans to which the Euro-Rate Option applies and
subject to Sections 2.08(d) and 2.08(e), an appropriate Euro-Rate Interest
Period for each Euro-Rate Portion of the Revolving Credit Loans to be made on
such Borrowing Date.

                  2.06. Making Revolving Credit Loans. Subject to Section 9.03,
the Agent shall, promptly after receipt by it of a Loan Request pursuant to
Section 2.05 (but not later than noon (Pittsburgh, Pennsylvania time) on the
Borrowing Date for same day funding and 2:00 p.m. (Pittsburgh, Pennsylvania
time) on the second Business Day preceding any Borrowing Date for which any
Portion of the Revolving Credit Loans to be made on such Borrowing Date bears
interest at the Euro-Rate Option), notify the Lenders of its receipt of such
Loan Request specifying: (i) the proposed Borrowing Date and the time and method
of disbursement of such Revolving Credit Loan; (ii) the amount of such Revolving
Credit Loan and the applicable Euro-Rate Portions and Euro-Rate Interest Periods
(if any); and (iii) the apportionment among the Lenders of the Revolving Credit
Loans as determined by the Agent in accordance with Section 2.02 hereof. Subject
to Section 9.03, each Lender shall remit the principal amount of each Revolving
Credit Loan to the Agent such that the Agent is able to, and the Agent shall, to
the extent the Lenders have made funds available to it for such purpose, fund
such Revolving Credit Loan to the Borrower in Dollars and immediately available
funds at the Principal Office prior to 2:00 P.M. (Pittsburgh, Pennsylvania time)
on the Borrowing Date, provided that if any Lender fails to remit such funds to
the Agent in a timely manner, or any Lender fails to advise

                                     - 25 -
<PAGE>

the Agent of its intention not to fund, then the Agent may elect in its sole
discretion to fund with its own funds the Revolving Credit Loan of such Lender
on the Borrowing Date.

                  2.07. Revolving Credit Notes. The obligation of the Borrower
to repay the aggregate unpaid principal amount of the Revolving Credit Loans
made to the Borrower by each Lender, together with interest thereon, shall be
evidenced by a promissory note of the Borrower dated the Closing Date in
substantially the form attached hereto as Exhibit "A" payable to the order of
each Lender in a face amount equal to the Revolving Credit Commitment of such
Lender.

                  2.08. Interest Payments, Interest Rates and Certain Related
Payments Pertaining to the Revolving Credit Loans.

                           (a) Interest. The Revolving Credit Notes shall bear
interest on the actual unpaid principal amount thereof from time to time
outstanding from the date thereof until payment in full at the rates of interest
set forth in Section 2.08(b). The Borrower shall pay accrued interest on the
unpaid principal balance of the Revolving Credit Notes in arrears:

                                    (i) with respect to the Base Rate Portion,
at the rate specified in the Base Rate Option, (A) on the last Business Day of
each Fiscal Quarter during the term of the Revolving Credit Commitment, (B) at
maturity, whether by acceleration or otherwise, of the Revolving Credit Notes
and (C) thereafter on demand until all amounts evidenced by the Revolving Credit
Notes are paid in full; and

                                    (ii) with respect to each Euro-Rate Portion,
at the rate specified in the Euro-Rate Option, (A) on the last day of the
Euro-Rate Interest Period applicable thereto; provided, however, if the
Euro-Rate Interest Period chosen for any EuroRate Portion exceeds three (3)
months, interest on that Euro-Rate Portion shall be due and payable at the end
of every three (3) months during such Euro-Rate Interest Period and on the last
day of such Euro-Rate Interest Period, (B) at the maturity, whether by
acceleration or otherwise, of the Revolving Credit Notes and (C) thereafter on
demand until all amounts evidenced by the Revolving Credit Notes are paid in
full.

                           (b) Interest Rate Options. During the term hereof,
the Borrower shall have the option of electing, from time to time, one or more
of the Interest Rate Options set forth below to be applied to the Revolving
Credit Loans.

                                    (i) Base Rate Option. Interest under this
Interest Rate Option shall accrue, for the Base Rate Portion of the Revolving
Credit Loans outstanding, at a rate per annum equal to the Base Rate. The Base
Rate shall be adjusted automatically from time to time upon each change in the
Prime Rate or the Federal Funds Effective Rate, as the case may be, and in
accordance with the provisions of Section 2.08(c).

                                    (ii) Euro-Rate Option. Interest under this
Interest Rate Option shall accrue, for each Euro-Rate Portion of the Revolving
Credit Loans outstanding, for any Euro-Rate Interest Period selected, at a rate
per annum equal to the sum of (A) the Euro-Rate

                                     - 26 -
<PAGE>

plus (B) the Applicable Euro-Rate Margin as determined below. The rate of
interest established pursuant to the preceding sentence of this Section
2.08(b)(ii) for each Euro-Rate Portion shall be adjusted from time to time in
accordance with the provisions of Section 2.08(c).

For purposes of this Agreement, the term "Applicable Euro-Rate Margin" shall
mean the rate per annum set forth in the chart below which corresponds to the
range of ratios in which the Borrower's Consolidated Total Indebtedness to
Consolidated EBITDA Ratio as at the end of the preceding Fiscal Quarter falls:

                  Consolidated Total Indebtedness    Applicable Euro-Rate
                  to Consolidated EBITDA Ratio               Margin
                  -------------------------------    --------------------
                  Less than or equal to 1.5 to 1.0            1.00%

                  Greater than 1.5 to 1.0 but less
                  than or equal to 2.0 to 1.0                 1.25%

                  Greater than 2.0 to 1.0 but less
                  than or equal to 2.5 to 1.0                 1.75%

                  Greater than 2.5 to 1.0                     2.25%

All adjustments shall be determined as of the date the Borrower's quarterly
financial statements and Compliance Certificate are required to be delivered
pursuant to items (i) and (iii) of Section 6.02. The foregoing notwithstanding,
the Applicable Euro-Rate Margin from the Closing Date to and including the March
31, 2002 Delivery Date shall be 1.0%.

                           (c) Interest After Maturity. After the occurrence of
an Event of Default and during the continuation thereof, the Base Rate Portion
shall bear interest at a rate per annum which shall be two hundred (200) basis
points (2%) above the Base Rate otherwise in effect during such period. After
the occurrence of an Event of Default and during the continuation thereof, all
Euro-Rate Portions shall bear interest (i) until the end of the then current
Euro-Rate Interest Period for each such Euro-Rate Portion, at a rate per annum
which shall be two hundred (200) basis points (2%) above the sum of (A) the
Euro-Rate , plus (B) the Applicable Euro-Rate Margin otherwise in effect during
such period, and (ii) at the end of the then current Euro-Rate Interest Period
for each such Euro-Rate Portion, such Euro-Rate Portions shall automatically be
converted to the Base Rate Portion, and thereafter the interest rate shall be
calculated in accordance with the initial sentence of this Section 2.08(c).

                           (d) Interest Periods; Limitations on Elections. At
any time when the Borrower shall select, convert to or renew the Euro-Rate
Option to apply to all or any portion of the outstanding Revolving Credit Loans,
it shall elect one or more Euro-Rate Interest Periods as the case may be. All
the foregoing, however, is subject to the following:

                                    (i) any Euro-Rate Interest Period which
would otherwise end on a day which is not a Business Day shall be extended to
the next Business Day unless such

                                     - 27 -
<PAGE>

Business Day falls in the succeeding calendar month in which case such Euro-Rate
Interest Period shall end on the next preceding Business Day; and

                                    (ii) any Euro-Rate Interest Period which
begins on the last day of a calendar month or on a day for which there is no
numerically corresponding day in the subsequent calendar month during which such
Euro-Rate Interest Period is to end shall end on the last Business Day of such
subsequent month.

                                    Elections by the Borrower of the Euro-Rate
Option shall be subject to the following limitations:

                                    (i) The Euro-Rate Portion for each Euro-Rate
Interest Period shall be in an aggregate principal amount of $5,000,000 or more;
provided, however, that each increment in excess of $5,000,000 shall be
$1,000,000 or an integral multiple thereof;

                                    (ii) No Euro-Rate Interest Period may be
elected at any time that a Default or an Event of Default shall have occurred
and be continuing;

                                    (iii) No Euro-Rate Interest Period may be
elected which would end later than the Expiration Date;

                                    (iv) No Euro-Rate Interest Period may be
elected with regard to amounts outstanding which would be in excess of the
Revolving Credit Commitment or the Borrowing Base, whichever is less; and

                                    (v) At no time may there be more than four
(4) separate EuroRate Interest Periods in effect.

                           (e) Election, Renewal or Conversion of Interest Rate
Options. Elections or renewals of, or conversions to, the Base Rate Option shall
continue in effect until converted or renewed as hereinafter provided. Elections
or renewals of, or conversions to, the Euro-Rate Option shall expire as to each
Euro-Rate Portion at the expiration of the applicable Euro-Rate Interest Period.
At any time with respect to the Base Rate Portion or at the expiration of the
applicable Euro-Rate Interest Period with respect to any Euro-Rate Portion, the
Borrower may cause (subject to Subsection 2.08(d)) all or any part of the
principal amount of such portion to be converted to, or to be renewed under, the
Euro-Rate Option by notice to the Agent as hereinafter provided. Such notice (i)
shall be irrevocable, (ii) shall be given not later than noon (Pittsburgh,
Pennsylvania time) in the case of a conversion to or renewal of, either in whole
or in part, the Euro-Rate Option, not less than three (3) Business Days prior to
the proposed effective date for such conversion or renewal, and (iii) shall set
forth:

                                    (A) the effective date of such conversion or
         renewal, which shall be a Business Day;

                                    (B) the new Euro-Rate Interest Period(s)
         selected; and

                                     - 28 -
<PAGE>

                                    (C) with respect to each such Euro-Rate
         Interest Period, the aggregate principal amount of the corresponding
         Euro-Rate Portion.

At the expiration of each Euro-Rate Interest Period, any part (including the
whole) of the principal amount of the corresponding Euro-Rate Portion as to
which no notice of conversion or renewal has been received shall automatically
be converted to the Base Rate Option. The Agent shall promptly notify the
Borrower and the Lenders of any such automatic conversion.

                           (f) Notification of Election of an Interest Rate
Option. The Borrower, by an Authorized Officer, shall notify the Agent of each
election of an Interest Rate Option, each conversion from one Interest Rate
Option to another, the amount of the Revolving Credit Loans then outstanding to
be allocated to each Interest Rate Option and, where relevant, the Euro-Rate
Interest Periods as provided for in this Agreement. Any such communication may
be oral or written and if oral it shall be followed promptly by written
confirmation of such Interest Rate Option election executed by an Authorized
Officer of the Borrower.

                           (g) Calculation of Interest. Interest on the Base
Rate Portion shall be calculated on the basis of a 365 or 366 day year, as the
case may be, and the actual days elapsed. Interest on each Euro-Rate Portion
shall be calculated on the basis of a 360-day year and the actual days elapsed.
The calculation of the amount of interest due and owing to the Lenders shall be
evidenced by posting the amount of interest due under the Revolving Credit Notes
to the Loan Account established by the Agent pursuant to Section 2.14.

                           (h) Lawful Interest Rates Intended. In no event
whatsoever shall the interest rates charged hereunder exceed the highest rate
permissible under any law which a court of competent jurisdiction shall, in a
final determination, deem applicable hereto. In the event that such a court
determines that any Lender has received interest hereunder in excess of the
highest applicable rate, such Lender shall promptly refund such excess to the
Borrower, or at such Lender's option, apply such excess in reduction of the
principal balance of the Lender Obligations owing to the affected Lender.

                  2.09. Prepayments; Allocation of Repayments; Payment of Excess
Loans.

                           (a) Prepayments of Base Rate Portion. The Borrower,
upon oral or written notice to the Agent by an Authorized Officer of Borrower
given not later than 12:00 noon (Pittsburgh, Pennsylvania time) on the proposed
date for prepayment, may prepay without penalty or premium any or all of the
Base Rate Portion. Any oral notice of election hereunder shall be followed
immediately by written confirmation of such prepayment election executed by an
Authorized Officer of Borrower

                           (b) Prepayments of Euro-Rate Portions. Except as
otherwise provided in Section 2.10(c), the Borrower, upon oral or written notice
to the Agent by an Authorized Officer of Borrower given at least three (3)
Business Days prior to the proposed date for repayment, may prepay, all or any
part of such Euro-Rate Portion. If such Euro-Rate Portion is prepaid on the last
day of the Euro-Rate Interest Period applicable thereto, such prepayment shall
be without premium or penalty. If the Borrower prepays a Euro-Rate Portion other
than on the

                                     - 29 -
<PAGE>

last day of the Euro-Rate Interest Period applicable thereto, the Borrower
agrees to pay, in addition to the other amounts set forth in this Section
2.09(b), such additional amounts as may be necessary to compensate each Lender
for any loss (including loss of profit on a pre-tax basis) and any direct or
indirect costs, including the costs of reemployment of funds prepaid at rates
lower than the cost to such Lender of such funds. Such losses and costs shall be
specified in writing to the Borrower by the affected Lenders (and such
specifications shall set forth in reasonable detail the calculation of such
losses and costs) and such specifications shall, absent manifest error, be
binding and conclusive on the Borrower. Such prepayment shall include the then
outstanding principal amount of the Euro-Rate Portion being prepaid together
with accrued interest, fees and other amounts then due and payable on the amount
prepaid, to the day of such prepayment. Except as provided in this Section
2.09(b), there shall be no voluntary prepayment of any Euro-Rate Portion.

                           (c) Allocation of Repayments of Principal. Any
voluntary prepayment pursuant to this Section 2.09 hereof shall be applied first
to the repayment of any Euro-Rate Portion of the Revolving Credit Loans for
which its associated Euro-Rate Interest Period expires on the date of such
payment, second, to the reduction of the Base Rate Portion of the Revolving
Credit Loans, and third, to the reduction of such Euro-Rate Portions of the
Revolving Credit Loans as directed by the Borrower, and if the Borrower fails to
give such directions, or if a Default or Event of Default has occurred and is
continuing, to the reduction of such Euro-Rate Portions of the Revolving Credit
Loans as the Agent may select in its sole and absolute discretion. Any reduction
in any Euro-Rate Portion on a date other than the date on which its associated
Euro-Rate Interest Period expires may result in a funding loss for which the
Borrower will owe the Lenders an indemnity payment pursuant to Section 2.10
hereof.

                           (d) Payment of Excess Loans. In the event that at any
time either any Loan Account or the Borrowing Base Certificate most recently
delivered by the Borrower to the Agent shows that Total Utilization exceeds the
Borrowing Base, the Borrower shall repay, simultaneously with the delivery of
any such Borrowing Base Certificate to the Agent or upon demand by the Agent,
whichever is earlier, an amount which is sufficient to reduce the Total
Utilization so that, after such repayment, does not exceed the Borrowing Base.
Until such repayment occurs, the Lenders shall not be required to make
additional Loans to the Borrower and the Issuing Bank shall not be required to
issue any Letters of Credit.

                  2.10. Yield Protection.

                           (a) If any change subsequent to the Closing Date in
any Law or in the interpretation or application thereof by any Official Body or
in the compliance with any guideline or request from any Official Body, shall
make it unlawful for any Lender to maintain or give effect to its obligations as
contemplated under the Revolving Credit Commitment or for PNC Bank to maintain
or give effect to its obligation to make Swingline Loans, such Lender shall
notify the Borrower and the Agent in writing of its determination of such
unlawfulness and an explanation thereof. Thereafter, such Lender's obligation to
make available any further Revolving Credit Loans hereunder, and PNC Bank's
obligation to make available any further Swingline Loans hereunder shall
forthwith be cancelled and the Borrower, within thirty (30) days, or within such
longer period as may be allowed by Law, if any, shall repay to such Lender

                                     - 30 -
<PAGE>

so affected its pro rata share of the outstanding principal amount of all
Revolving Credit Loans and/or Swingline Loans, together with interest thereon to
the date of repayment and fees, if any, due as of the date of termination;
provided, however, that the affected Lender's obligations which are lawful, if
severable from those which are unlawful, shall continue, and with respect to
those obligations, this Agreement shall not terminate.

                           (b) If any Law issued after the Closing Date
(including, without limitation, Regulation D of the Federal Reserve Board), or
if any change on or after the Closing Date in any Law (including, without
limitation, Regulation D) or in the interpretation thereof by any Official Body
charged with the administration thereof, shall

                                    (i) subject any Lender to any tax, levy,
impost, charge, fee, duty, deduction or withholding or any kind hereunder (other
than any tax imposed or based upon the income of such Lender and payable to any
governmental or taxing authority in the United States of America, any state or
any municipality thereof); or

                                    (ii) change the basis of taxation of any
Lender with respect to payments of principal or interest or other amounts due
hereunder (other than any change which affects, and only to the extent that it
affects, the taxation by the United States, any state or any municipality
thereof based upon the income of such Lender); or

                                    (iii) impose, modify or deem applicable any
reserve, special deposit or similar requirements against assets held by any
Lender (other than such requirements which result solely from a change in the
credit quality of the Borrower or which are included in the determination of the
applicable rate of interest hereunder); or

                                    (iv) impose upon any Lender any other
obligation or condition with respect to this Agreement,

and the result of any of the foregoing is to increase the cost to any Lender, to
decrease the yield to any Lender with respect to the Revolving Credit Loans, the
Swingline Loans or any Letters of Credit, to reduce the income receivable by any
Lender or to impose any expenses upon any Lender with respect to the Revolving
Credit Loans, the Swingline Loans or any Letters of Credit by an amount which
any Lender reasonably deems material, then and in any such case:

                                             (A) the Lender so affected shall
promptly notify the Borrower and the Agent of the happening of such event;

                                             (B) the Borrower shall pay to the
affected Lender, within five (5) Business Days of written demand such amount as
will compensate such Lender for such additional cost or reduced amount,
calculated from the date of the notification by such Lender; and

                                             (C) the Borrower may pay to such
affected Lender the affected Revolving Credit Loan or Swingline Loan in full
without the payment of any additional amount other than on account of such
Lender's out-of-pocket losses (including funding losses, if

                                     - 31 -
<PAGE>

any, as provided in paragraph (c) below) not otherwise provided for in
subparagraph (B) immediately above and reduce such Lender's Revolving Credit
Commitment to zero with a corresponding reduction in the Revolving Credit
Commitments.

The Lender so affected shall present to the Borrower and the Agent a certificate
setting forth such increased cost or reduced amount. Such certificate shall set
forth in reasonable detail the calculation of the amount due and such Lender's
reasons for invoking the provisions of this Section 2.10(b). Such certificate
shall be conclusive evidence of the amount due thereunder except in the case of
manifest error in computation.

                           (c) The Borrower agrees to indemnify each Lender, on
demand, against any loss or expense (including loss of profit) which such Lender
may sustain or incur in liquidating or employing deposits from third parties
acquired to effect, fund or maintain such Euro-Rate Portions or any part thereof
as a consequence of (i) the failure of the Borrower to make a payment on the due
date thereof, (ii) the failure of the Borrower to borrow under, convert to or
renew under the Euro-Rate Option on the proposed effective date of such
borrowing, conversion or renewal, or (iii) the payment, prepayment or conversion
by the Borrower of any Euro-Rate Portions for any reason on a day other than the
last day of the applicable Euro-Rate Interest Period. Any Lender's determination
of an amount payable under this paragraph (c) shall be conclusive absent
manifest error.

                           (d) The foregoing notwithstanding, if the affected
Lender can mitigate or eliminate such increased cost or reduced yield by
transferring the Loans to another existing lending office of such Lender, such
Lender agrees to so transfer the Loans; provided, such transfer would not
subject such Lender to any unreimbursed cost or expense and would not otherwise
be disadvantageous to such Lender.

                  2.11. Special Provisions Relating to the Euro-Rate Option.

                           (a) Euro-Rate Unascertainable. In the event that on
any date on which a Euro-Rate Option would otherwise be set, the Agent shall
have determined (which determination shall be final and conclusive) that, by
reason of circumstances affecting the London interbank market, adequate,
reasonable means do not exist for ascertaining the EuroRate, the Agent shall
give prompt notice of such determination to the Borrower and the Lenders. Until
the Agent notifies the Borrower and the Lenders that the circumstances giving
rise to such determination no longer exist (which notice shall be given promptly
following receipt of knowledge thereof by the Agent), the right of the Borrower
to borrow under, convert to or renew the Euro-Rate Option shall be suspended.
Any notice of borrowing under, conversion to or renewal of the Euro-Rate Option
which was to become effective during the period of such suspension shall be
treated as a request to borrow under, convert to or renew the Base Rate Option
with respect to the principal amount therein specified.

                           (b) Inability to Offer Euro-Rate. In the event that
any Lender shall determine, in its sole discretion, that it is unable to obtain
deposits in the London interbank market in sufficient amounts and with
maturities related to such Euro-Rate Portions which would enable such Lender to
fund such Euro-Rate Portions, then such Lender shall notify the Borrower

                                     - 32 -
<PAGE>

and the Agent that the right of the Borrower to borrow under, convert to or
renew the Euro-Rate Option, shall be suspended with respect to such Lender. Such
notice shall set forth in reasonable detail such Lender's reasons for invoking
the provisions of this Section 2.11(b). Following notification of the suspension
of the Euro-Rate Option with respect to such Lender, the Borrower agrees to
negotiate with such Lender for a modified or alternative fixed rate of interest,
which will allow such Lender to realize its anticipated and bargained-for yield.
In the event that the Borrower and such Lender cannot agree on a modified or
alternative fixed rate of interest, any notice of borrowing under, conversion to
or renewal of the Euro-Rate Option which was to become effective during the
period of suspension shall be treated as a request to borrow under, convert to
or renew the Base Rate Option with respect to the principal amount specified
therein attributable to such Lender.

                           (c) Illegality. If any Lender shall determine in good
faith (which determination shall be final and conclusive) that compliance with
any Law (whether or not having the force of law) or the interpretation or
application thereof by any Official Body, has made it unlawful or impractical
for such Lender to make or maintain the Revolving Credit Loans under the
Euro-Rate Option, such Lender shall give notice of such determination to the
Borrower and the Agent, which notice shall set forth in reasonable detail such
Lender's reasons for invoking the provisions of this Section 2.11(c).
Notwithstanding any provision of this Agreement to the contrary, unless and
until such Lender shall have given notice to the Borrower and the Agent that the
circumstances giving rise to such determination no longer apply (which notice
shall be given promptly following receipt of knowledge thereof by such Lender):

                           (i) with respect to any Euro-Rate Interest Periods
thereafter commencing, interest in an amount equal to such Lender's Ratable
Share of the corresponding Euro-Rate Portion shall be computed and payable under
the Base Rate Option; and

                           (ii) on such date, if any, as shall be required by
law, an amount equal to such Lender's Ratable Share of any Euro-Rate Portion, as
the case may be, then outstanding shall be automatically converted to the Base
Rate Option and the Borrower shall pay to such Lender the accrued and unpaid
interest on such amounts to (but not including) such conversion date.

The Borrower shall pay any such Lender any additional amounts reasonably
necessary to compensate such Lender for any costs incurred by such Lender as a
result of any conversion pursuant to clause (ii) above which occurs on a day
other than the last day of the relevant Euro-Rate Interest Period, including,
but not limited to, any interest or fees payable by such Lender to lenders of
funds obtained by them to loan or maintain the lending of the Revolving Credit
Loans so converted. Such Lender shall furnish to the Borrower and the Agent a
certificate as to the amount necessary to compensate it for such costs, which
certificate shall set forth in reasonable detail the calculation of the amount
due. Such certificate shall constitute conclusive evidence of the amount due
thereunder absent any manifest error in computation. The Borrower shall pay such
amount to such Lender, as additional consideration hereunder, within ten (10)
days of the Borrower's receipt of such certificate.

                                     - 33 -
<PAGE>

                           (d) The foregoing notwithstanding, if the affected
Lender can continue to offer the Euro-Rate Option to the Borrower by
transferring the Revolving Credit Loans to another existing lending office of
such Lender, such Lender agrees to so transfer the Revolving Credit Loans;
provided, such transfer would not subject such Lender to any unreimbursed cost
or expense and would not otherwise be disadvantageous to such Lender.

                  2.12. Capital Adequacy. If after the Closing Date (i) any
adoption of or any change in or in the interpretation by an Official Body of any
Law or (ii) compliance with any Law, guideline or request of any Official Body
exercising control over banks or financial institutions generally or any court
(whether or not having the force of law), affects or would affect the amount of
capital required or expected to be maintained by any Lender or any corporation
controlling such Lender other than those resulting solely from a change in the
credit quality of the Borrower (a "Capital Adequacy Event"), and the result of
such Capital Adequacy Event is to reduce the rate of return on capital of such
Lender or any corporation controlling such Lender as a consequence thereof to a
level below that which such Lender could have achieved but for such Capital
Adequacy Event, taking into consideration such Lender's policies with respect to
capital adequacy, by an amount which such Lender deems to be material, such
Lender shall promptly deliver to the Borrower and the Agent a statement of the
amount necessary to compensate such Lender for the reduction in the rate of
return on its capital attributable to the commitments under this Agreement or
any of the Loan Documents (the "Capital Compensation Amount"). Each Lender shall
determine the Capital Compensation Amount in good faith, using reasonable
attribution and averaging methods. Each Lender shall, from time to time, furnish
to the Borrower and the Agent a certificate setting forth the amount so
determined and the calculations of such amount. Such certificate shall
constitute conclusive evidence of the amount due thereunder absent any manifest
error in computation. Such amount shall be due and payable by the Borrower to
such Lender ten (10) days after such notice is given. As soon as practicable
after any Capital Adequacy Event, such Lender shall submit to the Borrower and
the Agent estimates of the Capital Compensation Amounts that would be payable as
a function of such Lender's Revolving Credit Commitment hereunder.

                  2.13. Swingline Loans.

                           (a) Swingline Option. Subject to the provisions of
this Section 2.13, PNC Bank agrees that the Borrower may request Swingline
Loans, in an aggregate amount at any one time outstanding not to exceed the
lesser of (i) $10,000,000 or (ii) an amount which, when added to the aggregate
principal amount of (A) all other Loans then outstanding, (B) the aggregate
Stated Amount of outstanding Letters of Credit issued pursuant to Section 2.17
and (C) the aggregate amount of Unreimbursed L/C Draws does not exceed the
lesser of (x) the Revolving Credit Commitments of all Lenders, or (y) the
Borrowing Base. PNC Bank shall have no obligation to make Swingline Loans
hereunder on or after the Expiration Date.

                           (b) Limitations on and Evidence of Swingline Loans.
Each Swingline Loan or repayment of a Swingline Loan must be in the minimum
principal amount of $1,000,000 or, if in excess of $1,000,000, in integral
multiples of $500,000. Swingline Loans shall be repaid on the date agreed upon
by the Borrower and PNC Bank, not more than five (5) days after the making of
the Swingline Loan and not after the Expiration Date. The obligation of the
Borrower

                                     - 34 -
<PAGE>

to repay, prior to the Expiration Date, the aggregate unpaid principal amount
of such Swingline Loans advanced by PNC Bank shall be evidenced by the
Swingline Note substantially in the form of Exhibit "B" hereto. The principal
amount actually due and owing PNC Bank shall be the aggregate unpaid principal
amount of all disbursements of Swingline Loans made by PNC Bank, all as shown on
such PNC Bank Loan Account established pursuant to Section 2.14.

                           (c) Swingline Loan Procedure. The Borrower may from
time to time from the Closing Date to the Business Day prior to the Expiration
Date request a Swingline Loan. Such request shall be made not later than noon
(Pittsburgh, Pennsylvania time) on the date of the proposed Swingline Loan. Such
request may be made to the Agent orally or in writing and if orally confirmed in
writing. The Agent shall promptly notify PNC Bank of such request. PNC Bank
shall make the Swingline Loan available to the Borrower not later than 3:00 P.M.
(Pittsburgh, Pennsylvania time) on the same Business Day such Swingline Loan is
requested.

                           (d) Swingline Loan Interest. Interest on the
Swingline Loans shall accrue at the Base Rate or such other rate per annum as
offered by PNC Bank and accepted by the Borrower. After the occurrence of an
Event of Default and during the continuation thereof, the Swingline Loans shall
bear interest at a rate per annum which shall be two hundred (200) basis points
(2%) above the Base Rate otherwise in effect during such period.

                           (e) Risk Participation. Upon the disbursement of each
Swingline Loan and without any further action by or on behalf of such Lender,
each Lender hereby agrees to purchase, upon the occurrence of an Event of
Default, an undivided, full risk, nonrecourse participation in such Swingline
Loan, in an amount equal to (i) such Lender's Ratable Share (ii) multiplied by
the outstanding principal amount of such Swingline Loan on the date of the Event
of Default; provided, however, no Lender shall participate in any Swingline Loan
made after a notice of an Event of Default has been delivered pursuant to this
Agreement. If and to the extent PNC Bank receives payment of principal or
interest on a participated Swingline Loan, PNC Bank shall deliver to each Lender
such Lender's Ratable Share of such payment.

                  2.14. Loan Account. The Agent shall open and maintain on its
books a Loan Account in the name of the Borrower, with respect to (i) Revolving
Credit Loans and Swingline Loans made, repayments and prepayments of the
principal thereof, and the computation and payment of interest thereon, (ii)
Letters of Credit issued, or participated in, as the case may be, and draws and
reimbursements thereon or thereof, and (iii) the computation and payment of the
Fees due hereunder to the Lenders, the L/C Issuer and the Agent, and the
computation of other amounts due and sums paid to the Agent hereunder. Upon the
request of the Borrower to the Agent, the Agent shall promptly furnish to the
Borrower a statement of the Loan Account. The failure to record any such amount
shall not limit or otherwise affect the obligations of the Borrower hereunder or
under the Notes to repay all amounts owed hereunder and thereunder together with
all interest accrued thereon and all other fees and charges provided herein. The
Loan Account shall be conclusive evidence as to the amount at any time due to
the Lenders, the L/C Issuer and the Agent from the Borrower except in the case
of manifest error.

                  2.15. All Advances to Constitute One Loan. Notwithstanding the
limitations set forth herein, all Revolving Credit Loans, the Swingline Loans
and all other Lender Obligations

                                     - 35 -
<PAGE>

shall constitute one loan and all Indebtedness and obligations of the Borrower
to the Lenders under this Agreement and all other Loan Documents shall
constitute a general obligation of the Borrower. The parties hereto agree that
all of the rights of the Agent, the L/C Issuer, the Lenders and the Borrower set
forth in this Agreement and the other Loan Documents shall apply to any
amendment or modification of or supplement to this Agreement and the other Loan
Documents.

                  2.16. Use of Proceeds. The proceeds of the Revolving Credit
Loans and the Swingline Loans shall be used exclusively (i) to pay interest,
Fees and other costs, and expenses hereunder and under the other Loan Documents,
(ii) to repay any Unreimbursed L/C Draw, (iii) to repay in full any amounts
outstanding under the Existing Credit Agreement, and (iv) to fund capital
expenditures, working capital, acquisitions permitted by the terms hereof, and
general corporate purposes of the Borrower and its Subsidiaries. No proceeds of
any Loan may be used for any purpose which contravenes applicable law or any
provision of any Loan Document.

                  2.17. Letter of Credit Subfacility.

                           (a) At the request of the Borrower, the L/C Issuer
will issue for the account of the Borrower, on the terms and conditions
hereinafter set forth (including without limitation Article V hereof), one or
more Letters of Credit; provided, however, no Letter of Credit shall have an
expiry date later than the earlier of twenty-four (24) months from the date of
issuance or fifteen (15) days prior to the Expiration Date; and provided,
further, however, that in no event shall (i) the Stated Amount of the Letters of
Credit issued pursuant to this Section 2.17 exceed, at any one time,
$25,000,000, or (ii) the sum of aggregate outstanding principal balance of the
Revolving Credit Loans, the aggregate unpaid balance of outstanding Swingline
Loans, the aggregate unpaid balance of any Unreimbursed L/C Draws and the
aggregate Stated Amount of the Letters of Credit issued by the L/C Issuer under
this Section 2.17 exceed, at any one time, the aggregate Revolving Credit
Commitments or the Borrowing Base, whichever is less.

                           (b) (i) The Borrower shall pay (A) to the L/C Issuer
for its own account a fronting fee equal to 1/8 of 1% per annum (the "L/C
Fronting Fee") on the aggregate daily (computed at the opening of business and
on the basis of a year of 365 or 366 days, as the case may be, and actual days
elapsed) Stated Amount of the outstanding Letters of Credit for the period in
question, and (B) to the Agent for the ratable account of the Lenders a fee (the
"Letter of Credit Fee") equal to the Applicable Letter of Credit Fee per annum,
as determined below, on the aggregate daily (computed at the opening of business
and on the basis of a year of 365 or 366 days, as the case may be, and actual
days elapsed) Stated Amount of the outstanding Letters of Credit for the period
in question. The Letter of Credit Fee and the L/C Fronting Fee shall be payable
(A) quarterly in arrears on the last Business Day of each Fiscal Quarter
occurring during the term of this Agreement, (B) on the Expiration Date or (C)
upon acceleration of the Notes. Any issuance of an amendment to extend the
stated expiration date of a Letter of Credit or an amendment to increase the
Stated Amount of a Letter of Credit shall be treated as an issuance of a new
Letter of Credit for purposes of calculation of the Letter of Credit Fee and the
L/C Fronting Fee due and payable hereunder. After the occurrence of an Event of
Default and during the continuation thereof, the rate at which the Letter of
Credit Fee is calculated shall be increased by two hundred (200) basis points
(2%) above the pre-default rate.

                                     - 36 -
<PAGE>

                                    (ii) The Borrower shall also pay to the L/C
Issuer for the L/C Issuer's own account the L/C Issuer's customary documentation
fees payable with respect to the Letters of Credit as the L/C Issuer may
generally charge from time to time. Without limitation, the foregoing shall
include all charges and expenses paid or incurred by the L/C Issuer in
connection with any Letter of Credit, including without limitation: (A)
correspondents' charges, if any, (B) any and all reasonable out-of-pocket
expenses and charges of the L/C Issuer in connection with the performance,
administration, interpretation, collection and enforcement of this Agreement and
any Letter of Credit, including all reasonable legal fees and expenses, and (C)
any and all applicable reserve or similar requirements and any and all premiums,
assessments, or levies imposed upon the L/C Issuer by any Official Body.

                                    (iii) If by reason of (A) any change in any
Law or any change in the interpretation or application by any judicial or
regulatory authority of any Law or (ii) compliance by the L/C Issuer with any
direction, request or requirement (whether or not having the force of law) of
any Official Body:

                                             (A) the L/C issuer shall be subject
to any tax, levy, charge or withholding of any nature or to any variation
thereof or to any penalty with respect to the maintenance or fulfillment of its
obligations under this Section 2.17, whether directly or by such being imposed
on or suffered by the L/C Issuer;

                                             (B) any reserve, deposit or similar
requirement is or shall be applicable, imposed or modified in respect of the
Letters of Credit; or

                                             (C) there shall be imposed on the
L/C Issuer any other condition regarding this Section 2.17 or the Letters of
Credit;

and if the result of any of the foregoing is to directly or indirectly increase
the cost to the L/C Issuer of issuing or maintaining any Letter of Credit, or to
reduce the amount receivable in respect thereof by, the L/C Issuer, then and in
any such case the L/C Issuer may, at any time after the additional cost is
incurred or the amount receivable is reduced, notify the Borrower and the Agent,
and the Borrower shall pay on demand such amounts as the L/C Issuer may specify
to be necessary to compensate the L/C Issuer for such additional cost or reduced
receipt, together with interest on such amount from the date of the notice of
such event which results in such increased cost or reduction in amount
receivable until payment in full thereof at a rate equal at all times to the
Base Rate. The determination by the L/C Issuer of any amount due pursuant to
this Subsection 2.17(b)(ii) as set forth in a certificate setting forth the
calculation thereof, shall, in the absence of manifest error, be final and
conclusive and binding on all of the parties hereto.

For purposes of this Agreement, the term "Applicable Letter of Credit Fee" shall
mean the rate per annum set forth in the chart below which corresponds to the
range of ratios in which the Borrower's Consolidated Total Indebtedness to
Consolidated EBITDA Ratio as at the end of the preceding Fiscal Quarter falls:

         Greater than 2.5 to 1.0                                   2.25%

All adjustments shall be determined as of the date the Borrower's quarterly
financial statements and Compliance Certificate are required to be delivered
pursuant to items (i) and (iii) of Section 6.02. The foregoing notwithstanding,
the Applicable Letter of Credit Fee from the Closing Date to and including the
March 31, 2002 Delivery Date shall be 1.00%.

                           (c) Immediately upon the issuance of each Letter of
Credit and each increase in the Stated Amount thereof, each Lender hereby agrees
to irrevocably purchase and shall be deemed to have irrevocably purchased from
the L/C Issuer an undivided, full risk, non-recourse participation in such
Letter of Credit and drawings thereunder in an amount equal to such Lender's
Ratable Share of the maximum amount which is or at any time may become available
to be drawn thereunder. In the event that the L/C Issuer is required for any
reason to refund or repay to the Borrower, any guarantor or any other Person all
or any portion of any amount remitted to the L/C Issuer pursuant to this
Agreement, the Lenders shall promptly remit to the L/C Issuer, upon three (3)
Business Days' demand therefor, their respective Ratable Shares of the amount
which is so refunded or repaid.

                           (d) In the event any restrictions are imposed upon
the L/C Issuer or any of the Lenders by any Law of any Official Body having
jurisdiction over the banking activities of the L/C Issuer or any Lender which
would prevent the L/C Issuer from issuing the Letters of Credit or amending the
Letters of Credit or would prevent any Lender from honoring its obligations
under this Section 2.17, the commitment of the L/C Issuer to issue the Letters
of Credit or enter into any amendment with respect thereto shall be immediately
suspended. If any Lender believes any such restriction would prevent such Lender
from honoring its obligations under this Section 2.17, it shall promptly notify
the Agent. The Agent shall promptly notify the Borrower, the L/C Issuer and the
other Lenders of the existence and nature of (i) any restriction which would
cause the suspension of the commitment of the L/C Issuer to issue the Letters of
Credit or to enter into amendments with respect thereto and (ii) any restriction
which would prevent any Lender from honoring its obligations under this Section
2.17. The Borrower will thereupon undertake reasonable efforts to obtain the
cancellation of all outstanding Letters of Credit; provided, however, that the
refusal of any beneficiary of a Letter of Credit to surrender such Letter of
Credit will not be an Event of Default hereunder, provided that the Borrower
shall undertake good faith efforts to obtain substitute letters of credit for
the then existing and outstanding Letters of Credit. Nothing contained in this
Section 2.17 shall be deemed a termination of the Revolving Credit Commitments
and, in the event of a suspension of the commitment of the L/C Issuer to issue
Letters of Credit as set forth above, the Borrower may

                                     - 38 -
<PAGE>

continue to borrow under the Revolving Credit Commitments provided the
requirements of Section 5.02 are complied with.

                           (e) When the Borrower desires the issuance of a
Letter of Credit, the Borrower shall deliver a duly completed Application and
Agreement for Letter of Credit to the L/C Issuer, with a copy to the Agent, no
later than 10:00 A.M. (Pittsburgh, Pennsylvania time) at least three (3)
Business Days, or such shorter period as may be agreed to by the L/C Issuer, in
advance of the proposed date of issuance. Upon satisfaction of the conditions
set forth in Section 5.01 and, if applicable, Section 5.02, the L/C Issuer shall
be obligated to issue the Letter of Credit and shall notify the Agent and each
Lender of such issuance. In determining whether to pay under a Letter of Credit,
the L/C Issuer shall be responsible only to determine that the documents and
certificates required to be delivered under the Letter of Credit have been
delivered and that they comply on their face with the requirements of the Letter
of Credit.

                           (f) In the event of any request for drawing under a
Letter of Credit by the beneficiary thereof, the L/C Issuer shall immediately
notify the Borrower and the Agent, and the Borrower shall reimburse, or cause
the reimbursement of, the L/C Issuer on demand as set forth in the applicable
Application and Agreement for Letter of Credit in an amount in same day funds
equal to the amount of such drawing; provided, however, that anything contained
in this Agreement to the contrary notwithstanding, unless the Borrower shall
have notified the Agent and the L/C Issuer prior to such time that the Borrower
intends to reimburse the L/C Issuer for all or a portion of the amount of such
drawing with funds other than the proceeds of Revolving Credit Loans, the
Borrower shall be deemed to have given a Loan Request to the Agent requesting
the Lenders to make Revolving Credit Loans on the first Business Day immediately
following the date on which such drawing is honored in an aggregate amount equal
to the excess of the amount of such drawing over the amount received by the L/C
Issuer from such other funds in reimbursement thereof (the "Unreimbursed L/C
Draw"), plus accrued interest on such amount at the rate set forth in Subsection
2.08. Any such Revolving Credit Loan shall be deemed advanced to the Borrower.
If the Borrower shall be deemed to have given a Loan Request, then, subject to
satisfaction or waiver of the conditions specified in Section 5.02, the Lenders
shall, all as set forth in Section 2.17(g) hereof, on the first Business Day
immediately following the date of such drawing, make Revolving Credit Loans in
the aggregate amount of the Unreimbursed L/C Draw plus accrued interest on such
amount at the applicable rate set forth in Section 2.08. The proceeds of any
such Revolving Credit Loans shall be applied directly by the Agent upon receipt
from the Lenders to reimburse the L/C Issuer for the Unreimbursed L/C Draw plus
accrued interest on such amount. The foregoing shall not limit or impair the
obligation of the Borrower to reimburse the L/C Issuer on demand.

                           (g) In the event that the Borrower shall fail to
reimburse the L/C Issuer on demand as provided in the applicable Application and
Agreement for Letter of Credit and Section 2.17(f) above in an amount equal to
the amount of any drawing honored by the L/C Issuer under a Letter of Credit
plus accrued interest, the L/C Issuer shall promptly notify the Agent and each
Lender of the Unreimbursed L/C Draw plus accrued interest on such amount of such
drawing and of such Lender's respective participation therein. Each Lender shall
make available to the L/C Issuer an amount equal to its respective participation
in same day funds, at the office of the L/C Issuer specified in such notice, not
later than 12:00 Noon (Pittsburgh,

                                     - 39 -
<PAGE>

Pennsylvania time) on the Business Day after the date specified in such notice
by the L/C Issuer. In the event that any Lender fails to make available to the
L/C Issuer the amount of such Lender's participation in such Letter of Credit as
provided in this Section 2.17(g), the L/C Issuer shall be entitled to recover
such amount on demand from such Lender together with interest at the Federal
Funds Effective Rate for three (3) Business Days and thereafter at the Base
Rate. Nothing in this Section 2.17(g) shall be deemed to prejudice the right of
any Lender to recover its Ratable Share of the Unreimbursed L/C Draw from the
L/C Issuer pursuant to this Section 2.17(g) in the event that it is determined
by a court of competent jurisdiction that payment with respect to a Letter of
Credit by the L/C Issuer constituted gross negligence or willful misconduct on
the part of the L/C Issuer. The L/C Issuer shall distribute to each Lender which
has paid all amounts payable by it under this Section 2.17(g) with respect to a
Letter of Credit such other Lender's Ratable Share of all payments received by
the L/C Issuer from the Borrower in reimbursement of drawing honored by the L/C
Issuer under the Letter of Credit when such payments are received.

                           (h) The obligations of the Borrower under this
Agreement to reimburse the L/C Issuer for all drawings upon the Letters of
Credit shall be absolute, unconditional and irrevocable, and shall not be
subject to any right of set-off or counterclaim and shall be paid or performed
strictly in accordance with the terms of this Agreement, under all circumstances
whatsoever, including the following circumstances:

                                    (i) any lack of validity or enforceability
of this Agreement, any Letter of Credit or any of the Loan Documents;

                                    (ii) any amendment or waiver of any
provision of all or any of the Loan Documents;

                                    (iii) the existence of any claim, set-off,
defense or other rights which the Borrower may have at any time against any
beneficiary or any transferee of any Letter of Credit (or any Persons for whom
any such beneficiary or any such transferee may be acting), the L/C Issuer, the
Agent or any Lender (other than the defense of payment to the L/C Issuer in
accordance with the terms of this Agreement) or any other Person, whether in
connection with this Agreement, the Loan Documents or any transaction
contemplated hereby or thereby or any unrelated transaction;

                                    (iv) any draft, demand, certificate,
statement or document presented under any Letter of Credit, appearing on its
face to be valid and sufficient, but proving to be forged, fraudulent, invalid
or insufficient in any respect or any statement therein being untrue or
inaccurate in any respect whatsoever;

                                    (v) payment by the L/C Issuer under any
Letter of Credit against presentation of any document which does not comply with
the terms of the Letter of Credit, provided that such payment shall not have
constituted gross negligence or willful misconduct of the L/C Issuer;

                                     - 40 -
<PAGE>

                                    (vi) any other circumstance or happening
whatsoever, whether or not similar to any of the foregoing, not resulting from
gross negligence or willful misconduct of the L/C Issuer; and

                                    (vii) the fact that a Default or Event of
Default shall have occurred and be continuing.

                           (i) This Agreement is intended to supplement each
Application and Agreement for Letter of Credit executed by the Borrower and
delivered to the L/C Issuer. Whenever possible this Agreement is to be construed
as consistent with each Application and Agreement for Letter of Credit but, to
the extent that the provisions of this Agreement and each Application and
Agreement for Letter of Credit conflict, the terms of this Agreement shall
control.

                           (j) Existing Letters of Credit. As of the Closing
Date, each of the Existing Letters of Credit issued by the L/C Issuer and
outstanding on such date for the account of the Borrower and identified on
Schedule 2.17(j) shall be deemed to be Letters of Credit issued hereunder and
shall be subject to all of the terms and provisions of this Agreement. The
Borrower is hereby deemed to be the account party with respect to each such
Letter of Credit for all purposes thereunder and hereunder. Each Lender agrees
that its obligations with respect to Letters of Credit pursuant to this
Agreement shall include such Existing Letters of Credit. With respect to each
such Existing Letter of Credit, for the period commencing on the Closing Date,
the Borrower shall pay all fees and commissions set forth in this Agreement at
the times and in the manner herein set forth. The obligations of the Borrower
under each application for letter of credit and credit or reimbursement
agreement (together with any related amendments) executed with respect to the
Existing Letters of Credit are hereby expressly assumed by the Borrower and each
such application for letter of credit and credit or reimbursement agreement, as
amended, is hereby deemed an Application and Agreement for Letter of Credit
executed and delivered hereunder. Such existing credit or reimbursement
agreements shall be superseded in their entirety by this Agreement which shall
apply to Existing Letters of Credit as well as all Letters of Credit issued
hereunder on and after the Closing Date.

                           (k) Obligations Absolute. Notwithstanding any other
provision of this Agreement, each Lender hereby agrees that its obligation to
participate in each Letter of Credit issued in accordance herewith and its
obligation to make the payments to be made by it under this Section 2.17 is
absolute, irrevocable and unconditional and shall not be affected by any event,
condition or circumstance whatever. The failure of any Lender to make any such
payment shall not relieve any other Lender of its funding obligation hereunder
on the date due, but no Lender shall be responsible for the failure of any other
Lender to meet its funding obligations hereunder.

                           (l) In addition to amounts payable as elsewhere
provided in this Section 2.17, the Borrower hereby agrees to protect, indemnify,
pay and save the Agent or the L/C Issuer harmless from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable attorneys' fees) which the Agent or the L/C Issuer may
incur or be subject to as a consequence, direct or indirect, of (i) the issuance
of the

                                     - 41 -
<PAGE>

Letters of Credit or any amendment thereto, other than as a result of the gross
negligence or willful misconduct of the Agent or the L/C Issuer as determined by
a court of competent jurisdiction, (ii) the failure of the L/C Issuer to honor a
draw under any Letter of Credit if the L/C Issuer in good faith and upon advice
of counsel believes that it is prohibited from making such payment as a result
of any requirement of Law or of any Official Body, or (iii) any material breach
by the Borrower of any representation, warranty, covenant, term or condition in,
or the occurrence of any default under, any document related to the issuance or
any amendment of the Letters of Credit. If any proceeding shall be brought or
threatened against the Agent or the L/C Issuer by reason of or in connection
with any event described in clauses (i) through (iii) above, the Agent shall
promptly notify the Borrower in writing, and the Borrower shall assume the
defense thereof, including the employment of counsel and payment of all costs of
litigation. Notwithstanding the preceding sentence, the Agent and the L/C Issuer
shall have the right to employ their own counsel and to determine its own
defense of such action in any such case, but the fees and expenses of such
counsel shall be at the expense of the Agent or the L/C Issuer, as the case may
be, unless (x) the employment of such counsel shall have been authorized in
writing by the Borrower, (y) the Borrower, after the aforementioned notice of
the action, shall not have employed counsel to have charge of such defense or
(z) if the position of the Borrower is adverse or contrary to the position
advocated by the Agent or the L/C Issuer, as the case may be. In each case
described in clauses (x), (y) and (z) immediately above the reasonable fees and
expenses of counsel for the Agent or the L/C Issuer, as the case may be shall be
borne by the Borrower. The Borrower shall not be liable for any settlement of
any such action affected without its consent.

                           (m) The L/C Issuer is hereby expressly authorized and
directed to honor any request for payment which is made under and in compliance
with the terms of any Letter of Credit without regard to, and without any duty
on the L/C Issuer's part to inquire into, the existence of any disputes or
controversies between the Borrower, the beneficiary of any Letter of Credit or
any other Person, or the respective rights, duties or liabilities of any of them
or whether any facts or occurrences represented in any of the documents
presented under any Letter of Credit are true or correct. Furthermore, the
Borrower fully understands and agrees that the L/C Issuer's sole obligation to
the Borrower shall be limited to honoring requests for payment made under and in
compliance with the terms of any Letter of Credit, the Application and Agreement
for Letter of Credit therefor and this Agreement and the L/C Issuer's obligation
remains so limited even if the L/C Issuer may have assisted the Borrower in the
preparation of the wording of any Letter of Credit or any documents required to
be presented thereunder or that the L/C Issuer may otherwise be aware of the
underlying transaction giving rise to any Letter of Credit and this Agreement.

                           (n) As between the Borrower and the L/C Issuer, the
Borrower assumes all risks of the acts and omissions of, or misuse of the
Letters of Credit by, the beneficiaries of the Letters of Credit. In furtherance
and not in limitation of the foregoing, the L/C Issuer shall not be responsible:
(i) for the form, validity, sufficiency, accuracy, genuineness or legal effect
of any document submitted by any party in connection with the application for or
the issuance or amendment of the Letters of Credit, even if it should in fact
prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent
or forged; (ii) for the validity or sufficiency of any instrument transferring
or assigning or purporting to transfer or assign the

                                     - 42 -
<PAGE>

Letters of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason;
(iii) for failure of a beneficiary of a Letter of Credit to comply fully with
conditions required in order to draw upon such Letter of Credit; (iv) for
errors, omissions, interruptions or delays in transmission or delivery of any
messages, by mail, cable, telegraph, telecopy, telex or otherwise, whether or
not they be in cipher; (v) for errors in interpretation of technical terms; (vi)
for any loss or delay in the transmission or otherwise of any document required
in order to make a draw under the Letters of Credit or of the proceeds thereof;
(vii) for the misapplication by a beneficiary of any Letter of Credit of the
proceeds of any drawing under such Letter of Credit; (viii) for any consequences
arising from causes beyond the control of the L/C Issuer, including, without
limitation, any Law; and (ix) for any other circumstances whatsoever in making
or failing to make payment under a Letter of Credit; except that the Borrower
shall have a claim against the L/C Issuer, and the L/C Issuer shall be liable to
the Borrower, to the extent, but only to the extent, of any direct, as opposed
to consequential, damages suffered by the Borrower by a court of competent
jurisdiction to be the result of (i) the L/C Issuer's willful misconduct or
gross negligence in determining whether documents presented under a Letter of
Credit comply with the terms of the Letter of Credit, (ii) the L/C Issuer's
willful misconduct or gross negligence in paying a draw under a Letter of Credit
to any Person other than the beneficiary of such Letter of Credit or its lawful
successor, representative or assign (or as otherwise directed in writing by the
beneficiary of such Letter of Credit) or (iii) the L/C Issuer's willful failure
to pay under a Letter of Credit after the presentation to it by the beneficiary
of such Letter of Credit or its lawful successor, representative or assign of a
sight draft and certificate or other documents strictly complying with the terms
and conditions of such Letter of Credit, unless the L/C Issuer in good faith and
upon advice of counsel believes that it is prohibited by law or other legal
authority from making such payment. None of the above shall affect, impair, or
prevent the vesting of any of the L/C Issuer's rights or powers hereunder.

                           (o) Except for the L/C Issuer's obligations to issue
Letters of Credit hereunder and its obligations under such Letters of Credit,
the L/C Issuer shall have no liability to the Borrower from a reduction of the
L/C Issuer's credit rating or any deterioration in its financial condition.

                           (p) The Borrower shall bear and pay all reasonable
expenses of every kind (including all reasonable attorneys' fees) of the
enforcement of any of the L/C Issuer's rights under this Agreement or the
Letters of Credit, or of any claim or demand by the L/C Issuer against the
Borrower, or of any actual or attempted sale, exchange, enforcement, collection,
maintenance, retention, insurance, compromise, settlement, release, delivery on
trust receipt, or other security agreement, or delivery of any such security,
and of the receipt of proceeds thereof, and will repay to the L/C Issuer any
such expenses incurred by the L/C Issuer.

                           (q) In furtherance and extension and not in
limitation of the specific provisions hereinabove set forth, any action taken or
omitted by the L/C Issuer under or in connection with the Letters of Credit or
the related sight drafts or certificates or documents, if taken or omitted in
good faith, shall not put the L/C Issuer under any resulting liability to the
Borrower.

                                     - 43 -
<PAGE>

                           (r) Whenever appropriate to prevent unjust enrichment
and to the end that the Borrower shall bear substantially all of the risks
relative to any Letter of Credit and the underlying transactions, the L/C Issuer
shall be subrogated (for purposes of defending against the Borrower's claims and
proceeding against others to the extent of the L/C Issuer's liability to the
Borrower) to the Borrower's rights against any Person who may be liable to the
Borrower on any underlying transaction, to the rights of any holder in due
course or Person with similar status against the Borrower, and to the rights of
the beneficiary or its assignee or person with similar status against the
Borrower.

                           (s) Except and to the extent inconsistent with the
specific provisions hereof, this Agreement, each Letter of Credit hereunder and
all transactions in connection therewith shall be interpreted, construed and
enforced according to: (i) the "Uniform Customs and Practice for Documentary
Credits" (1993 Revision), International Chamber of Commerce Publication No. 500
and subsequent revisions thereof which shall supersede inconsistent provisions
of applicable law to the extent not prohibited by applicable law and (ii) the
laws of the Commonwealth of Pennsylvania, including, without limitation, the
Uniform Commercial Code, and excluding conflict of laws rules.

                  2.18. Taxes. Each Lender that is not incorporated under the
laws of the United States of America or a state thereof agrees that it will
deliver to the Borrower and the Agent (i) two duly completed copies of United
States Internal Revenue Service Form 1001 or 4224 or successor applicable form,
as the case may be (assuming that it is entitled to do so), and (ii) two duly
completed copies of Internal Revenue Service Form W-8 or W-9 or successor
applicable form. Each such Lender also agrees to deliver to the Borrower and the
Agent two further copies of the said Form 1001 or 4224 and Form W-8 or W-9, or
successor applicable forms or other manner of certification, as the case may be,
on or before the date that any such form expires or becomes obsolete or
otherwise is required to be resubmitted as a condition to obtaining an exemption
from withholding tax or after the occurrence of any event requiring a change in
the most recent form previously delivered by it to the Borrower and the Agent,
and such extensions or renewals thereof as may reasonably be requested by the
Borrower or the Agent, unless in any such case an event (including, without
limitation, any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Lender from duly completing
and delivering any such form with respect to it and such Lender so advises the
Borrower and the Agent. Such Lender shall certify (i) in the case of Form 1001
or 4224, that it is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes (assuming
that it is entitled to do so) and (ii) in the case of Form W-8 or W-9, that it
is entitled to an exemption from United States backup withholding tax.

                  2.19. Payments. All payments and prepayments to be made in
respect of principal, interest, Unreimbursed L/C Draws, Fees, or other amounts
due from the Borrower hereunder shall be payable prior to 11:00 A.M.
(Pittsburgh, Pennsylvania time) on the date when due without presentment,
demand, protest or notice of any kind, all of which are hereby expressly waived
by the Borrower, and without setoff, counterclaim or other deduction of any
nature, and an action therefor shall immediately accrue. Such payments shall be
made to the Agent at the Principal Office for the ratable account of the Lenders
or L/C Issuer, as the case

                                     - 44 -
<PAGE>

may be, in Dollars and in immediately available funds, and the Agent shall
promptly distribute such amounts to the Lenders or L/C Issuer, as the case may
be, in immediately available funds in accordance with the terms and provisions
of Section 9.10 of this Agreement. The Agent's, the L/C Issuer's and each
Lender's statement of account, ledger or other relevant record shall, in the
absence of manifest error, be conclusive as the statement of the amount of
principal of and interest on the Revolving Credit Loans, the Swingline Loans,
the Unreimbursed L/C Draws, Fees and other amounts owing under this Agreement
and shall be deemed an "account stated." Notwithstanding anything herein to the
contrary, (i) any administration or underwriting fee paid by the Borrower to the
Agent shall be solely for the account of the Agent, (ii) any L/C Fronting Fees
paid by the Borrower shall be solely for the account of the L/C Issuer and (iii)
any interest paid on any Unreimbursed L/C Draw to the extent a Lender has not
been required to honor or has not honored its funding obligations pursuant to
Section 2.17(g) hereof shall be solely for the account of the L/C Issuer.

                  2.20. Substitution of Lender. In the event any Lender (i)
gives notice under Sections 2.10 (Yield Protection), 2.11(b) (Inability to Offer
Euro-Rate), 2.11(c) (Illegality) or 2.12 (Capital Adequacy), (ii) does not fund
Revolving Credit Loans because the making of such Loans would contravene any Law
applicable to such Lender, (iii) does not approve any action as to which consent
of the Required Lenders is requested by the Borrower and obtained hereunder, or
(iv) becomes subject to the control of an Official Body (other than normal and
customary supervision), then, if the Borrower designates one or more substitute
institutions to purchase the Loans and assume the Revolving Credit Commitments
of such Lender, such Lender will at the Borrower's request sell its Loans and
assign its rights under this Agreement to such substitution institutions, with
reasonable promptness after such designation in accordance with Section 10.05,
for a payment equal to the principal amount of its Loans, plus all accrued and
unpaid interest and Fees to but excluding the date of purchase, plus any other
amounts accrued or payable to such Lender under this Agreement to but excluding
the date of purchase, plus any amount that would be payable to such Lender under
Section 2.10(c) (as if such purchase were treated as a prepayment of the
outstanding Loans to such Lender), together with any other loss or expense
incurred by it (or by a Participant in the related Loans or Revolving Credit
Commitment); provided that all of the provisions of Section 10.05(b) must first
be complied with, and provided, further that the Agent may only be replaced
subject to the requirements of Section 9.13 (Successor Agent) . Nothing in this
Section 2.20 limits the rights of the Agent, the Documentation Agents, the
Lenders, PNC Bank, or the L/C Issuer under any provisions of any of the Loan
Documents.

                                   ARTICLE III
                   LOAN DISBURSEMENT ACCOUNT, GUARANTEES, ETC.

                  3.01. Loan Disbursement Account. To induce the Lenders, the
Agent, the Documentation Agents and the L/C Issuer to enter into this Agreement
and to make available to the Borrower the credit accommodation herein set forth,
the Borrower shall maintain at all times during this Agreement with the Agent,
at the Agent's office in Pittsburgh, Pennsylvania, a demand deposit account (the
"Loan Disbursement Account"), into which proceeds of Revolving Credit Loans,
Swingline Loans and other monies transferred to the Borrower hereunder shall be

                                     - 45 -

to the Agent the consolidated annual audited financial statements of the
Borrower and its Subsidiaries for the Fiscal Year ended December 31, 2001. All
such financial statements are complete and correct in all material respects and
fairly present the consolidated financial condition of the Borrower and its
Subsidiaries in all material respects and the results of their operations as of
the dates and for the periods referred to, and have been prepared in accordance
with GAAP throughout the period included.

                           (ii) Accuracy of Financial Statements. The Borrower
and its Subsidiaries have no liabilities, contingent or otherwise, that are not
disclosed in the financial statements referred to in clause (i) above and that

ultimately,

                                     - 48 -
<PAGE>

of purchasing or carrying margin stock (within the meaning of any Margin
Regulation). No part of the proceeds of any Revolving Credit Loan or Swingline
Loan has been or will be used, immediately, incidentally or ultimately, to
purchase or carry any margin stock or to extend credit to others (including,

carrying any margin stock or to refund or retire Indebtedness originally
incurred for such purpose, or for any purpose which entails a violation of or
which is inconsistent with the provisions of the Margin Regulations of the Board
of Governors of the Federal Reserve System. The Borrower does not intend to
hold, and shall not permit its Subsidiaries to hold, margin stock. Neither the
Borrower not any of its Subsidiaries intends to use any portion of the proceeds
of the Loans, directly or indirectly, to purchase during the underwriting
period, or for thirty (30) days thereafter, Ineligible Securities being
underwritten by a Section 20 Subsidiary.

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

affiliated group of companies which files consolidated federal tax returns. All
such federal tax returns that are required by law to be filed have been filed or
properly extended. All taxes, assessments and other governmental charges levied
upon members of such affiliated group or any of their respective properties,
assets, income or franchises which are due and payable have been paid in full
other than (i) those presently payable without penalty or interest, (ii) those
which are being contested in good faith by appropriate proceedings and (iii)
those which, if not paid, would not, in the aggregate, constitute a Material
Adverse Change; and as to each of items (i), (ii) and (iii) the affiliated group
has established reserves for such claim as have been determined to be adequate
by application of GAAP consistently applied. There are no agreements or waivers
extending the statutory period of limitations applicable to any consolidated
federal income tax return of the Borrower and its consolidated Subsidiaries for
any period, except as set forth on Schedule 4.11.

                  4.12. Consents and Approvals. No consent, approval, exemption,
order or authorization of, or a registration or filing with any Official Body or
any other Person is required by any Law or any agreement in connection with the
execution, delivery and carrying out of this Agreement and the Loan Documents to
which the Borrower or any Subsidiary Guarantor is a party, except as listed on
Schedule 4.12 attached hereto, all of which items set forth on Schedule 4.12
shall have been obtained or made on or prior to the Closing Date.

                  4.13. No Event of Default; Compliance with Instruments. No
event has occurred and is continuing and no condition exists or will exist after
giving effect to the borrowings to be made on the Closing Date under the Loan
Documents which constitutes an Event of Default or a Default. Neither the
Borrower nor any of its Subsidiaries is in violation of (i) any term of its
certificate of incorporation, by-laws or other organizational documents or (ii)
any material agreement or instrument to which it is a party or by which it or
any of its properties may be subject or bound where such violation would
constitute a Material Adverse Change.

                  4.14. Compliance with Laws. The Borrower and its Subsidiaries
are in compliance in all material respects with all applicable Laws (other than
Environmental Laws, which are addressed in Section 4.20) in all jurisdictions in
which the Borrower, and its Subsidiaries, are presently or will be doing
business except where the failure to do so would not, individually or in the
aggregate, constitute a Material Adverse Change.

registered or required to be registered under the Investment Company Act of 1940
or under the "control" of an "investment company" as such terms are defined in
the Investment Company Act of 1940, as amended from time to time, and shall not
become such an "investment company" or under such "control. " Neither the
Borrower nor any Subsidiary Guarantor is a "holding company" or a "subsidiary
company" of a "holding company" or an "affiliate" of a "holding company" within

to time. The Borrower is not subject to any Law of any Official Body (in each
case whether United States federal, state or local, or other) having
jurisdiction over the Borrower, which purports to restrict or regulate its
ability to borrow money, or to extend or obtain credit, or to pledge its
interests in the Loan Disbursement Account. No Subsidiary Guarantor is subject
to any Law of any Official Body (in each case whether United States federal,
state or local, or other) having jurisdiction over such Subsidiary Guarantor
which purports to restrict or regulate its ability to borrow money or to extend
or obtain credit.

                  4.16. Plans and Benefit Arrangements. Except as set forth on

are in compliance in all material respects with any applicable provisions of
ERISA with respect to all Benefit Arrangements, Plans and Multiemployer Plans.
There has been no Prohibited Transaction with respect to any Benefit Arrangement
or any Plan (other than a Multiemployer Plan) or, to the knowledge of the
Borrower, with respect to any Multiemployer Plan or Multiple Employer Plan,
which could result in any material liability of the Borrower or any other member
of the ERISA Group. The Borrower and all members of the ERISA Group have made
when due any and all payments required to be made under any agreement relating
to a Multiemployer Plan or a Multiple Employer Plan or any Law pertaining

fulfilled in all material respects their obligations under the minimum funding
standards of ERISA, (ii) have not incurred any liability to the PBGC (other than

when due.

                           (iii) Neither the Borrower nor any other member of
the ERISA Group has instituted or intends to institute proceedings to terminate
any Plan.

                           (iv) No event requiring notice to the PBGC under
Section 302(f)(4)(A) of ERISA has occurred or is reasonably expected to occur
with respect to any Plan, and no amendment with respect to which security is
required under Section 307 of ERISA has been made or is reasonably expected to
be made to any Plan.

                           (v) Neither the Borrower nor any other member of the
ERISA Group has incurred or reasonably expects to incur any material withdrawal
liability under ERISA to any Multiemployer Plan or Multiple Employer Plan.
Neither the Borrower nor any other member of the ERISA Group has been notified
by any Multiemployer Plan or Multiple Employer Plan that such Multiemployer Plan
or Multiple Employer Plan has been terminated within the meaning of Title IV of
ERISA and, to the knowledge of the Borrower, no Multiemployer Plan or Multiple
Employer Plan is reasonably expected to be reorganized or terminated, within the
meaning of Title IV of ERISA.

                           (vi) To the extent that any Benefit Arrangement is
insured, the Borrower and all members of the ERISA Group have paid when due all
premiums required to be paid for all periods ending through and including the
Closing Date. To the extent that any Benefit Arrangement is funded other than
with insurance, the Borrower and all members of the ERISA Group have made when
due all contributions, to the extent required by applicable Law or the terms of
such Benefit Arrangement to be paid for all periods ending through and including
the Closing Date.

                  4.17. Title to Properties. The Borrower and each of its
Subsidiaries have good title to, or a valid leasehold interest in, all their
respective real and personal property, except to the extent the failure to have
such title or leasehold interests is not reasonably likely, individually or in
the aggregate, to result in a Material Adverse Change, and none of such property
is subject to any Lien except Permitted Liens.

                  4.18. Insurance. There are in full force and effect for the
benefit of the Borrower and its Subsidiaries insurance policies and bonds
providing adequate coverage from reputable and financially sound insurers in
amounts sufficient to insure the assets and risks of the Borrower and its
Subsidiaries in accordance with prudent business practice in the industry of the
Borrower and its Subsidiaries. No notice has been given or claim made and to the
knowledge of the Borrower, no grounds exist, to cancel or void any of such
policies or bonds or to reduce the coverage provided thereby.

Laws including, but not limited to, those related to equal employment
opportunity and affirmative action, labor relations, minimum wage, overtime,
child labor, medical insurance continuation, worker adjustment and relocation
notices, immigration controls and worker and unemployment compensation, except
where the failure to comply would not constitute a Material Adverse Change.
There are no outstanding grievances, arbitration awards or appeals therefrom
arising out of the Labor Contracts or current or, to the knowledge of the
Borrower, threatened strikes, picketing, handbilling or other work stoppages or
slowdowns at facilities of the Borrower or any Subsidiary of the Borrower which
in any case would constitute a Material Adverse Change. All payments due from
Borrower or any of its Subsidiaries on Receivable of employee health and welfare
insurance which could reasonably be expected to have a Material Adverse Change
if not paid have been paid or accrued as a liability on the books of Borrower or
such Subsidiary.

any Subsidiary of the Borrower or any prior or subsequent owner of any of the
Property is a potentially responsible party under the Comprehensive
Environmental Response, Cleanup and Liability Act, 42 U.S.C. Section 9601, et
seq., in connection with the Property which Environmental Complaint is
reasonably expected to result in any Material Adverse Change, and the Borrower
has no reason to believe that such an Environmental Complaint is reasonably
likely to be received. There are no pending or, to the knowledge of the
Borrower, threatened Environmental Complaints relating to the Borrower, any
Subsidiary of the Borrower or, to the Borrower's knowledge, without any inquiry,
any prior or subsequent owner of the Property pertaining to, or arising out of,
any Environmental Conditions in connection with the Property, which
Environmental Complaints are reasonably expected to result in any Material
Adverse Change.

                           (ii) Except for conditions, violations or failures
which individually and in the aggregate are not reasonably likely to result in a
Material Adverse Change, there are no circumstances at, on or under the Property
that constitute a breach of or non-compliance with any of the Environmental
Laws, and there are no past or present Environmental Conditions at, on or under
the Property or, to the knowledge of the Borrower, without any inquiry at, on or
under adjacent property, that prevent compliance with the Environmental Laws at
the Property.

                           (iii) Neither the Property nor any structures,
improvements, equipment, fixtures, activities or facilities thereon or
thereunder contain or use Regulated Substances except in compliance with
Environmental Laws, other than such containment or use which individually and in
the aggregate is not reasonably likely to result in any Material Adverse Change.
There are no processes, facilities, operations, equipment or any other
activities at, on or under the Property, or, to the Borrower's knowledge,
without any inquiry, at, on or under adjacent property, that currently result in
the release or threatened release of Regulated Substances on to the Property in

                                     - 52 -
<PAGE>

threatened releases are not likely to result in a Material Adverse Change.

                           (iv) There are no underground storage tanks, or
underground piping associated with such tanks, used for the management of
Regulated Substances at, on or under the Property that are not in compliance
with all Environmental Laws, other than those with respect to which the failure
to comply with Environmental Laws is not reasonably likely, either individually
or in the aggregate, to result in a Material Adverse Change, and there are no
abandoned underground storage tanks or underground piping associated with such
tanks, previously used for the management of Regulated Substances at, on or
under the Property that have not been either abandoned in place, or removed, in
accordance with the Environmental Laws, other than those with respect to which
the failure to comply with Environmental Laws is not reasonably likely, either

                           (v) The Borrower and each Subsidiary of the Borrower
have all material permits, licenses, authorizations and approvals necessary
under the Environmental Laws for the conduct of the respective businesses of the
Borrower and each Subsidiary of the Borrower as presently conducted, other than

reasonably likely, either individually or in the aggregate, to result in a
Material Adverse Change. The Borrower and each Subsidiary of the Borrower have
submitted all notices, reports and other filings required by the Environmental
Laws to be submitted to an Official Body which pertain to past and current
operations on the Property, except for any failure to submit which would not be
reasonably likely to result in a Material Adverse Change.

                           (vi) Except for violations which individually and in
the aggregate are not likely to result in a Material Adverse Change, all past
and present on-site generation, storage, processing, treatment, recycling,
reclamation or disposal of Solid Waste at, on, or under the Property and all

payment with all other Indebtedness of the Borrower, except Indebtedness of the
Borrower to the extent secured by Permitted Liens. The obligations of a
Subsidiary Guarantor under a Subsidiary Guaranty executed by such Subsidiary
Guarantor rank at least pari passu in priority of payment with all other
Indebtedness of such Subsidiary Guarantor except Indebtedness of such Subsidiary
Guarantor to the extent secured by Permitted Liens. There is no Lien upon or
with respect to any of the properties or income of the Borrower or any of its
Subsidiaries which secures Indebtedness or other obligations of any Person
except for Permitted Liens.

                  4.22. Solvency. On the date hereof, and as of the date of each
advance of the Revolving Credit Loan and issuance or renewal of any Letter of

Change.

hereunder and under the other Loan Documents shall be immediately due and
payable, without presentment, demand, protest or notice of any kind, all of
which are hereby expressly waived; further, during the thirty (30) day period
referred to in item (m) the Lenders shall be under no further obligation to make

                           (c) If an Event of Default shall occur and be
continuing, any Lender, the Agent or the L/C Issuer to whom any obligation is
owed by the Borrower hereunder or under any other Loan Document, of such Lender,
Agent or L/C Issuer and any branch, subsidiary or affiliate of such Lender,
Agent or L/C Issuer anywhere in the world shall each have the right, in addition
to all other rights and remedies available to it, without notice to the
Borrower, to set-off against and apply to the then unpaid balance of all the
Loans and all other obligations of the Borrower hereunder or under any other
Loan Document, any debt owing to, and any other funds held in any manner for the
account of, the Borrower by such Lender, the Agent or the L/C Issuer or by such
branch, subsidiary or affiliate, 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 hereafter maintained by the
Borrower for its own account (but not including funds held in custodian or trust
accounts) with such Lender, the Agent or the L/C Issuer or such branch,
subsidiary or affiliate. Such right shall exist in each case whether or not any
Lender, the Agent or the L/C Issuer shall have made any demand under this
Agreement or any other Loan Document, whether or not such debt owing to or funds
held for the account of the Borrower is or are matured or unmatured and

creditor under applicable Law, all of which rights and remedies shall be
cumulative and non-exclusive, to the extent permitted by Law. The Agent may, and
upon the request of the Required Lenders shall, exercise all post-default rights
granted to the Agent, the L/C Issuer and the Lenders under the Loan Documents or
applicable Law; and

                           (e) Upon the occurrence of any Event of Default
described in the foregoing Sections 8.01(m) or (n) or upon the declaration by
the Required Lenders of any other Event of Default and the termination of the
Revolving Credit Commitments, the obligation of the L/C Issuer to issue or amend
Letters of Credit shall terminate, the L/C Issuer or the Agent may provide
written demand to any beneficiary of a Letter of Credit to present a draft
against such Letter of Credit, and an amount equal to the maximum amount which
may at any time be drawn under the Letters of Credit then outstanding (whether
or not any beneficiary of such Letters of Credit shall have presented, or shall
be entitled at such time to present, the drafts or other documents required to
draw under the Letters of Credit) shall automatically become immediately due and
payable, without presentment, demand, protest or other requirements of any kind,
all of which are hereby expressly waived by the Borrower; provided that the
foregoing shall not affect in any way the obligations of the Lenders to purchase
from the L/C Issuer participations in the unreimbursed amount of any drawings
under the Letters of Credit as provided in Section 2.17(c). So long as the
Letters of Credit shall remain outstanding, any amounts declared due pursuant to

                                     - 74 -
<PAGE>

this Section 8.02(e) with respect to the outstanding Letters of Credit when
received by the Agent shall be deposited and held by the Agent in an interest
bearing account denominated in the name of the Agent for the benefit of the
Agent, the Lenders and the L/C Issuer over which the Agent shall have sole
dominion and control of withdrawals (the "Cash Collateral Account") as cash
collateral for the obligation of the Borrower to reimburse the L/C Issuer in the
event of any drawing under the Letters of Credit and upon any drawing under such
Letters of Credit in respect of which the Agent has deposited in the Cash
Collateral Account any amounts declared due pursuant to this Section 8.02(e),
the Agent shall apply such amounts held by the Agent to reimburse the L/C Issuer
for the amount of such drawing. In the event that any Letter of Credit in
respect of which the Agent has deposited in the Cash Collateral Account any
amounts described above is cancelled or expires or in the event of any reduction
in the maximum amount available at any time for drawing under the Letters of
Credit outstanding, the Agent shall apply the amount then in the Cash Collateral
Account designated to reimburse the L/C Issuer for any drawings under the
Letters of Credit less the maximum amount available at any time for drawing
under the Letters of Credit outstanding immediately after such cancellation,
expiration or reduction, if any, to the payment in full of the outstanding
Lender Obligations, and second, to the payment of any excess, to the Borrower.

                                   ARTICLE IX
                                   THE AGENTS

                  9.01. Appointment and Grant of Authority. Each of the Lenders
and the L/C Issuer hereby appoints PNC Bank, National Association, and PNC Bank,
National Association, hereby agrees to act, as the Agent under this Agreement
and the other Loan Documents. Each of the Lenders and the L/C Issuer hereby
appoints each of US Bank National City Bank of Pennsylvania and LaSalle Bank
National Association, as Documentation Agents hereunder. The Agent shall have
and may exercise such powers under this Agreement and the other Loan Documents
as are specifically delegated to it by the terms hereof or thereof, together
with such other powers as are incidental thereto. Without limiting the
foregoing, the Agent, on behalf of the Lenders and the L/C Issuer, is authorized
to execute all of the Loan Documents (other than this Agreement) and to accept
all of the Loan Documents and all other agreements, documents or instruments
reasonably required to carry out the intent of the parties to this Agreement.

                  9.02. Delegation of Duties. The Agent may perform any of its
duties hereunder by or through agents or employees (provided such delegation
does not constitute a relinquishment of duties as the Agent hereunder) and,
subject to Sections 9.07 and 10.03 hereof, shall be entitled to engage and pay
for the advice or services of any attorneys, accountants, or other experts
concerning all matters pertaining to duties hereunder and to rely upon any
advice so obtained.

                  9.03. Reliance by Agent on Lenders for Funding. Unless the
Agent shall have received notice from a Lender prior to any Borrowing Date that
such Lender will not make available to the Agent such Lender's portion of net
disbursements of Loans, the Agent may assume that such Lender has made such
portion available to the Agent and the Agent may, in reliance upon such
assumption, make Loans to the Borrower. If and to the extent that such

                                     - 75 -
<PAGE>

Lender has not made such portion available to the Agent on or prior to any
Borrowing Date, such Lender and the Borrower severally agree to repay to the
Agent immediately upon demand, in immediately available funds, such unpaid
amount, together with interest thereon for each day from the applicable
Borrowing Date until such amount is repaid to the Agent, at (i) in the case of
the Borrower, at the rate of interest then in effect for such Loan and (ii) in
the case of such Lender, at the Federal Funds Effective Rate. If such Lender
shall repay to the Agent such corresponding amount, such amount shall constitute
a Loan made by such Lender for purposes of this Agreement. The failure by any
Lender to pay its portion of a Revolving Credit Loan made by the Agent shall not
relieve any other Lender of the obligation to pay its portion of net
disbursements of Revolving Credit Loans on any Borrowing Date, but no Lender
shall be responsible for the failure of any other Lender to make its net share
of Revolving Credit Loans to be made by such other Lender on such Borrowing
Date.

                  9.04. Non-Reliance on Agents. Each Lender and the L/C Issuer
agree that (i) it has, independently and without reliance on the Agent or the
Documentation Agents, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Borrower and its
Subsidiaries and decision to enter into this Agreement and (ii) that it will,
independently and without reliance upon the Agent or the Documentation Agents,
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own analysis and decisions in taking or not taking
action under this Agreement. Except as otherwise provided herein or under any
other Loan Document, neither the Agent nor any Documentation Agent shall have
any duty to keep the Lenders or the L/C Issuer informed as to the performance or
observance by the Borrower of this Agreement or any other document referred to
or provided for herein or to inspect the properties or books of the Borrower or
any of its Subsidiaries. The Agent and the Documentation Agents, in the absence
of gross negligence or willful misconduct, shall not be liable to any Lender or
the L/C Issuer for their failure to relay or furnish to the Lender any
information.

                  9.05. Responsibility of Agents and Other Matters.

                           (a) Ministerial Nature of Duties. As between the
Lenders, the L/C Issuer and itself, the Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement or in the
other Loan Documents, and those duties and responsibilities shall be subject to
the limitations and qualifications set forth in this Article IX. The duties of
the Agent shall be ministerial and administrative in nature. The Documentation
Agents shall have no duties as agents hereunder.

                           (b) Limitation of Liability. As between the Lenders,
the L/C Issuer, the Agent and the Documentation Agents, neither the Agent nor
either Documentation Agent nor any of their respective directors, officers,
employees or agents shall be liable, in the absence of gross negligence or
willful misconduct, for any action taken or omitted (whether or not such action
taken or omitted is within or without the Agent's responsibilities and duties
expressly set forth in this Agreement) under or in connection with this
Agreement or any other instrument or document in connection herewith. Without
limiting the foregoing, neither the Agent nor either Documentation Agent nor any
of their representative directors, officers, employees or its agents, shall be
responsible for, or have any duty to examine (i) the genuineness, execution,
validity,

                                     - 76 -
<PAGE>

effectiveness, enforceability, value or sufficiency of (A) this Agreement or any
of the other Loan Documents or (B) any other document or instrument furnished
pursuant to or in connection with this Agreement, (ii) the collectability of any
amounts owed by the Borrower to the Agent, the Documentation Agents, the Lenders
or the L/C Issuer, (iii) the truthfulness of any recitals or statements or
representations or warranties made to the Agent, the Documentation Agents or the
Lenders in connection with this Agreement, (iv) any failure of any party to this
Agreement to receive any communication sent, including any telegram, telex,
teletype, telecopy, bank wire, cable, or telephone message or any writing,
application, notice, report, statement, certificate, resolution, request, order,
consent letter or other instrument or paper or communication entrusted to the
mails or to a delivery service, or (v) the assets or liabilities or financial
condition or results of operations or business or creditworthiness of the
Borrower or any of its Subsidiaries.

                           (c) Reliance. The Agent shall be entitled to act, and
shall be fully protected in acting upon, any telegram, telex, teletype,
telecopy, bank wire or cable or any writing, application, notice, report,
statement, certificate, resolution, request, order, consent, letter or other
instrument or paper or communication believed by the Agent in good faith to be
genuine and correct and to have been signed or sent or made by a proper Person.
The Agent may consult counsel and shall be entitled to act, and shall be fully
protected in any action taken in good faith, in accordance with advice given by
counsel. The Agent may employee agents and attorneys-in-fact and shall not be
liable for the default or misconduct of any such agents or attorneys-in-fact
selected by the Agent with reasonable care. The Agent shall not be bound to
ascertain or inquire as to the performance or observance of any of the terms,
provisions or conditions of this Agreement or any of the other Loan Documents on
the part of the Borrower.

                           (d) Copies of Notices. The Agent hereby undertakes to
promptly deliver to the Lenders copies of financial statements, written reports
and other written notices received by the Agent from the Borrower pursuant to
Sections 6.02, 6.03 or 6.05 hereof.

                  9.06. Actions in Discretion of Agent; Instructions from the
Lenders. The Agent agrees, upon the written request of the Required Lenders, to
take or refrain from taking any action of the type specified as being within the
Agent's rights, powers or discretion herein or under any Loan Documents,
provided that the Agent shall not be required to take any action which exposes
the Agent to personal liability or which is contrary to this Agreement or any
other Loan Document or applicable Law. In the absence of a request by the
Required Lenders, the Agent shall have authority, in its sole discretion, to
take or not to take any such action, unless this Agreement specifically requires
the consent of the Required Lenders or all of the Lenders. Any action taken or
failure to act pursuant to such instructions or discretion shall be binding on
the Lenders and the L/C Issuer, subject to Section 9.05(b) hereof. Subject to
the provisions of Section 9.05(b), no Lender shall have any right of action
whatsoever against the Agent as a result of the Agent acting or refraining from
acting hereunder in accordance with the instructions of the Required Lenders.

                  9.07. Indemnification. To the extent the Borrower does not
reimburse and save harmless the Agent or the Documentation Agents according to
the terms hereof for and from all costs, expenses and disbursements in
connection herewith, such costs, expenses and disbursements, shall be borne by
the Lenders ratably in accordance with respective Lender's

                                     - 77 -
<PAGE>

Ratable Share. Each Lender hereby agrees on such basis (i) to reimburse the
Agent and the Documentation Agents for such Lender's Ratable Share of all such
reasonable costs, expenses and disbursements on request and (ii) to the extent
of each such Lender's Ratable Share, to indemnify and save harmless the Agent
and the Documentation Agents against and from any and all losses, obligations,
penalties, actions, judgments and suits and other costs, expenses and
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against the Agent and the Documentation Agents, other than as a
consequence of gross negligence or willful misconduct on the part of the Agent
and the Documentation Agents, arising out of or in connection with this
Agreement, the other Loan Documents or any other agreement, instrument or
document in connection herewith or therewith, or any request of the Required
Lenders, including without limitation the reasonable costs, expenses and
disbursements in connection with defending itself against any claim or liability
related to the exercise or performance of any of its powers or duties under this
Agreement, the other Loan Documents, or any of the other agreements, instruments
or documents delivered in connection herewith or the taking of any action under
or in connection with any of the foregoing.

                  9.08. Agents' Rights as Lenders. With respect to the Revolving
Credit Commitment of the Agent and the Documentation Agents as Lenders
hereunder, any Loans of the Agent or the Documentation Agents under this
Agreement, the Agent's and the Documentation Agents' Ratable Share of any
Unreimbursed L/C Draws, the participation as a Lender, and as to PNC Bank, as
the L/C Issuer under this Agreement the other Loan Documents and any other
agreements, instruments and documents delivered pursuant hereto, and the
issuance of any Letter of Credit under the terms hereof, the Agent and the
Documentation Agents shall have the same rights and powers, duties and
obligations under this Agreement, the other Loan Documents or any other
agreement, instrument or document as any Lender and may exercise such rights and
powers and shall perform such duties and fulfill such obligations as though it
were not the Agent, as the case may be. The Agent and the Documentation Agents
may accept deposits from, lend money to, and generally engage, and continue to
engage, in any kind of business with the Borrower or any of its Subsidiaries.

                  9.09. Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of an Event of Default unless the Agent
has received written notice from a Lender or the Borrower referring to this
Agreement, describing such Event of Default and stating that such notice is a
"notice of default".

                  9.10. Payment to Lenders. Except as otherwise set forth in
Section 9.03 hereof, promptly after receipt from the Borrower of any principal
repayment of the Revolving Credit Loans or any Unreimbursed L/C Draw, interest
due on the Revolving Credit Loans or any Unreimbursed L/C Draws, and any Fees
(other than the underwriting fee and the administration fee paid to the Agent
and the L/C Fronting Fee paid to the L/C Issuer) or other amounts due under any
of the Loan Documents, the Agent shall distribute to each Lender that Lender's
Ratable Share of the funds so received except that funds received from the
Borrower or a Subsidiary Guarantor to reimburse the L/C Issuer for drawings on
Letters of Credit (other than a Lender's Ratable Share of such reimbursement
payment to the extent such Lender has complied fully with any funding
obligations under Section 2.17(g) hereof) or to fund any risk participant in the
Letters of Credit or to pay the L/C Fronting Fee shall be paid solely for the
account of L/C

                                     - 78 -
<PAGE>

Issuer. If the Agent fails to distribute collected funds received by 2:00 P.M.
on any Business Day by 3:00 P.M. of such Business Day or collected funds
received after 2:00 P.M. on any Business Day by 3:00 P.M. the next Business Day
the funds shall bear interest until distributed at the Federal Funds Effective
Rate. The Agent agrees to make its best efforts to provide telephonic notice to
each Lender that it is in receipt of funds from the Borrower and the day on
which it will commence a wire transfer of such Lender's share of such funds.

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

                  9.12. Equalization of Lenders. Each borrowing and each payment
or prepayment by, or for the account of, the Borrower with respect to principal,
interest, Fees, or other amounts due from the Borrower hereunder to the Lenders
with respect to the Revolving Credit Loans, shall (except as provided in Section
2.10, 2.12, 2.17(b) or 9.03 hereof) be made in proportion to the Revolving
Credit Loans outstanding from each Lender or, if no such Revolving Credit Loans
are then outstanding, in proportion to the Ratable Share of each Lender. Each
payment of Unreimbursed L/C Draws shall be made for the account of the L/C
Issuer. The Lenders agree among themselves that, with respect to all amounts
received by any Lender (in its capacity solely as a Lender) or any such holder
for application on any obligation hereunder or under any Note or under any such
participation, whether received by voluntary payment, by realization upon
security, by the exercise of the right of set-off or banker's lien, by
counterclaim or by any other non-pro rata source, equitable adjustment will be
made in the manner stated in the following sentence so that, in effect, all such
excess amounts will be shared ratably among the Lenders and such holders in
proportion to their interest in payments under the Notes, except as otherwise
expressly provided herein. The Lenders or any such holder receiving any such
amount shall purchase for cash, from each of the other Lenders, an interest in
such Lender's Revolving Credit Loans in such amount as shall result in a ratable
participation by the Lenders and each such holder in the aggregate unpaid amount
under the Notes, provided that if all or any portion of such excess amount is
thereafter recovered from the Lender or the holder making such purchase, such
purchase shall be rescinded and the purchase price restored to the extent of
such recovery, together with interest or other amounts, if any, required by Law
(including court order) to be paid by the Lender or the holder making such
purchase.

                  9.13. Successor Agent. The Agent may resign as the Agent upon
sixty (60) days' written notice to the Lenders and the Borrower. If such notice
shall be given, the Lenders shall appoint from among the Lenders a successor
agent for the Lenders, during such 60-day period, which successor agent shall be
reasonably satisfactory to the Borrower, to serve as agent hereunder and under
the several documents, the forms of which are attached hereto as exhibits, or
which are referred to herein. If at the end of such 60-day period the Lenders
have not appointed such a successor, the Agent shall procure a successor
reasonably satisfactory to the Lenders and the Borrower, to serve as agent for
the Lenders hereunder and under the several documents, the forms of which are
attached hereto as exhibits, or which are referred to herein.

                                     - 79 -
<PAGE>

Any such successor agent shall succeed to the rights, powers and duties of the
Agent. Upon the appointment of such successor agent or upon the expiration of
such 60-day period (or any longer period to which the Agent has agreed), 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. After any retiring Agent's resignation hereunder as
the Agent, the provisions of this Article IX shall inure to the benefit of such
retiring Agent as to any actions taken or omitted to be taken by it while it was
the Agent under this Agreement. A Documentation Agent may resign upon ten (10)
days prior written notice to the Agent.

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

                  9.15. Beneficiaries. Except as expressly provided herein, the
provisions of this Article IX are solely for the benefit of the Agent, the
Documentation Agents, the Lenders and the L/C Issuer, and the Borrower shall not
have any rights to rely on or enforce any of the provisions hereof. In
performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Lenders and does not assume and shall not be deemed to
have assumed any obligation toward or relationship of agency or trust with or
for the Borrower.

                  9.16. Termination of Existing Bank Credit Agreements. It is
the intent of the parties hereto that on the Closing Date the Borrower shall
comply with each of items (i) through (xiv) inclusive of Section 6.2. Upon
satisfaction of all of the provisions of Section 6.1 and Section 6.2 and the
satisfaction of the terms of any applicable payoff letter delivered in
connection with the Existing Credit Agreement, the Existing Credit Agreements
shall be terminated.

                  9.17. Waiver of Consequential Damages. To the extent permitted
by applicable law, the Borrower hereby waives its right to pursue any claim
against the Agent, the Syndication Agents, the Lenders and each of their
respective directors, officers, employees, attorneys, agents and Affiliates on
any theory of liability for special, indirect, consequential or punitive damages
(as opposed to direct or actual damages).

                                    ARTICLE X
                               GENERAL PROVISIONS

                  10.01. Amendments and Waivers. The Required Lenders, or the
Agent with the consent in writing of the Required Lenders, and the Borrower may,
subject to the provisions of this Section 10.01, from time to time enter into
written supplemental agreements to this Agreement and the other Loan Documents
for the purpose of adding or deleting any provisions or otherwise changing,
varying or waiving in any manner the rights of the Lenders, the Agent or

                                     - 80 -
<PAGE>

the obligor thereunder or the conditions, provisions or terms thereof or waiving
any Event of Default thereunder or consenting to an action of any of the
Borrower or any of its Subsidiaries, but only to the extent specified in such
written agreements; provided, however, that no such supplemental agreement
shall, without the consent of all the Lenders:

                           (i) waive an Event of Default by the Borrower in any
payment of principal, interest, Fees or other amounts due hereunder and under
any of the other Loan Documents, or otherwise postpone any schedule payment date
of any of the foregoing;

                           (ii) reduce the interest rate relating to the
Revolving Credit Loans or change the definition of the terms Base Rate, Prime

Euro-Rate Reserve Percentage or Federal Funds Effective Rate so as to decrease
the interest rate relating to the Revolving Credit Loans;

                           (iii) change the Expiration Date;

                           (iv) reduce any Fee;

                           (v) change the definition of the term Required
Lenders; or

                           (vi) amend or waive the provisions of this Section
10.01.

provided, further, however, that no such supplemental agreement hereto shall
increase any Lender's Revolving Credit Commitment without the consent of such
Lender.

                  Any such supplemental agreement shall apply equally to each of
the Lenders and the L/C Issuer and shall be binding upon the Borrower, the
Lenders, the Agent and the Documentation Agents, all future holders of the Notes
and all Participants. In the case of any waiver, the Borrower, the Lenders, the
L/C Issuer, the Agent and the Documentation Agents shall be restored to former
positions and rights, and any Event of Default waived shall be deemed to be
cured and not continuing, but no such waiver shall extend to any subsequent or
other Event of Default, or impair any right consequent thereon.

                  10.02. Taxes. The Borrower shall pay any and all stamp,
document, transfer and recording taxes, filing fees and similar impositions
payable or hereafter determined by the Agent, the Documentation Agents, the
Lenders or the L/C Issuer to be payable in connection with this Agreement, the
other Loan Documents and any other documents, instruments and transactions
pursuant to or in connection with any of the Loan Documents. The Borrower agrees
to save the Agent, the Documentation Agents, the Lenders and the L/C Issuer
harmless from and against any and all present and future claims or liabilities
with respect to, or resulting from, any delay in paying or failure to pay any
such taxes or similar impositions.

                                    (i) Any Lender may, in the ordinary course
of its commercial lending business and in accordance with applicable law, and
without the consent of the Borrower, at any time sell to one or more
Participants (which Participants may be Affiliates of such Lender)
Participations in the Revolving Credit Commitment of such Lender or any
Revolving Credit Loan, the Note, or other interest of such Lender hereunder. In
the event of any such sale of a Participation, such Lender's obligations under
this Agreement to the Borrower shall remain unchanged, such Lender shall remain
solely responsible for its performance under this Agreement, such Lender shall
remain the holder of the Note made payable to it for all purposes under this
Agreement (including all voting rights hereunder) and the Borrower shall
continue to deal solely and directly with such Lender in connection with such

Euro-Rate Reserve Percentage, or Applicable Euro-Rate Margin so as to decrease
the interest rate relating to the Revolving Credit Loans, (C) extension of the
term of either Revolving Credit Commitment, or (D) postponement of the scheduled

                           (b) Assignments. Subject to the remaining provisions
of this Section 10.05(b), any Lender may at any time, in the ordinary course of
its commercial lending business, in accordance with applicable law, sell to one
or more Purchasing Lenders (which Purchasing Lender may be affiliates of the
Transferor Lender), all or a portion of its rights and obligations under this
Agreement and the Note then held by it, pursuant to an Assignment and Assumption
Agreement substantially in the form of Exhibit "F" and satisfactory to the
Agent, executed by the

                                     - 85 -
<PAGE>

Transferor Lender, such Purchasing Lender, the Agent and the Borrower; subject,
however to the following requirements:

                                    (i) The Agent and the Borrower must each
give its prior consent to any such assignment which consent shall not be
unreasonably withheld; it being agreed that it shall not be deemed unreasonable
for the Borrower to decline to consent to such assignment if (A) such assignment
would result in incurrence of additional costs to the Borrower under Section
2.10, 2.11 or 2.12, or (B) the proposed assignee has not provided to the
Borrower any tax forms received under Section 10.05(d); provided, however, no
consent is required for the transfer by a Lender to its Affiliate so long as the
conditions in clauses (A) and (B) immediately above are satisfied;

                                    (ii) Each such assignment must be in a
minimum amount of $5,000,000, or, if in excess of $5,000,000, in integral
multiples of $1,000,000;

                                    (iii) each such assignment shall be of a
constant, and not a varying, percentage of the Transferor Lender's Revolving
Credit Commitment outstanding Revolving Credit Loans and all other rights and
obligations under this Agreement and the other Loan Documents; and

                                    (iv) The Transferor Lender shall pay to the
Agent, for its own Account, a fee of $3,500 for each such assignment (the
"Assignment Fee").

                  Upon the execution, delivery, acceptance and recording of any
such Assignment and Assumption Agreement, from and after the Transfer Effective
Date determined pursuant to such Assignment and Assumption Agreement, (i) the
Purchasing Lender thereunder shall be a party hereto as a Lender and, to the
extent provided in such Assignment and Assumption Agreement, shall have the
rights and obligations of a Lender hereunder with a Revolving Credit Commitment
as set forth therein, and (ii) the Transferor Lender thereunder shall, to the
extent provided in such Assignment and Assumption Agreement, be released from
its obligations under this Agreement as a Lender. Such Assignment and Assumption
Agreement shall be deemed to amend this Agreement to the extent, and only to the
extent, necessary to reflect the addition of such Purchasing Lender as a Lender
and the resulting adjustment of Ratable Share arising from the purchase by such
Purchasing Lender of all or a portion of the rights and obligations of such
Transferor Lender under this Agreement and the Notes. On or prior to the
Transfer Effective Date, the Borrower shall execute and deliver to the Agent, in
exchange for the surrendered Notes held by the Transferor Lender, new Notes to
the order of such Purchasing Lender in an amount equal to the Revolving Credit
Commitment assumed by it and purchased by it pursuant to such Assignment and
Assumption Agreement, and new Notes to the order of the Transferor Lender in an
amount equal to the Revolving Credit Commitment retained by it hereunder.

                           (c) Assignment Register. The Agent shall maintain at
its address referred to in Section 10.04(b) a copy of each Assignment and
Assumption Agreement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders and the amount of the
Revolving Credit Loans owing to each Lender from time to time. The entries in
the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the

                                     - 86 -
<PAGE>

Agent, the Lender and the L/C Issuer may treat each Person whose
name is recorded in the Register as the owner of the Revolving Credit Loans
recorded therein for all purposes of this Agreement. The Register shall be
available at the office of the Agent for inspection by the Borrower or any
Lender at any reasonable time and from time to time upon reasonable prior
notice.

                           (d) Withholding of Income Taxes. At least five (5)
Business Days prior to the first date on which interest or fees are payable
hereunder for the account of any Purchasing Lender or Participant, each
Purchasing Lender or Participant that is not incorporated under the laws of the
United States or a state thereof shall deliver to the Borrower and the
Transferor Lender two duly completed copies of United States Internal Revenue
Service Form W-9, 4224 or 1001 or other applicable form prescribed by the
Internal Revenue Service. Such form shall certify that such Purchasing Lender or
Participant is entitled to receive payments under this Agreement and the Notes
without deduction or withholding of any United States Federal income taxes, or
is subject to such tax at a reduced rate under an applicable tax treaty or under
United States Internal Revenue Service Form W-8, or another applicable form or a
certificate of such Purchasing Lender or Participant indicating that no such
exemption or reduced rate is allowable with respect to such payments. Each
Purchasing Lender or Participant which delivers a Form W-8, W-9, 4224 or 1001
further undertakes to deliver to the Borrower and its Transferor Lender two
additional copies of such form (or a successor form) on or before the date that
such form expires or becomes obsolete or otherwise is required to be resubmitted
as a condition to obtaining an exemption from withholding tax or after the
occurrence of any event requiring a change in the most recent form so delivered
by it, and such amendments thereto or extensions or renewals thereof as may be
reasonably required by the Borrower or its Transferor Lender, either certifying
that such Purchasing Lender or Participant is entitled to receive payments under
this Agreement and the Notes without deduction or withholding of any United
States Federal income taxes or is subject to such tax at a reduced rate under an
applicable tax treaty or stating that no such exemption or reduced rate is
allowable. The Borrower, in the case of a Purchasing Lender or Transferor Lender
in the case of a Participant shall be entitled to withhold United States Federal
income taxes at the full withholding rate, unless the Purchasing Lender or
Participant as the case may be establishes an exemption, or at the applicable
reduced rate, as established pursuant to this provisions of this Section
10.05(d).

                           (e) Assignments to Federal Reserve Bank. In addition
to the assignments permitted above, any Lender may assign and pledge all or any
portion of its Loans and Notes to any Federal Reserve Bank as collateral
security pursuant to Regulation A of the Board of Governors of the Federal
Reserve System and any Operating Circular issued by such Federal Reserve Bank.
No such assignment shall release the assigning Lender from its obligations and
duties hereunder or under the other Loan Documents.

                  10.06. Successors and Assigns.

                           (i) This Agreement shall be binding upon the Borrower
and the Agent, the Documentation Agent, the Lenders, the L/C Issuer and their
respective successors and assigns, and shall inure to the benefit of the
Borrower, the Agent, the Documentation Agents, the Lenders, the L/C Issuer and
respective successors and assigns; provided, however, that the

                                     - 87 -
<PAGE>

Borrower shall not assign its rights or duties hereunder or under any of the
other Loan Documents without the prior written consent of the Lenders.

                           (ii) Notwithstanding anything to the contrary
contained herein, any Lender (a "Granting Lender") may grant to a special
purpose funding vehicle (an "SPC") the option to fund all or any part of any
Loan that such Granting Lender would otherwise be obligated to fund pursuant to
this Agreement; provided that (A) nothing herein shall constitute a commitment
by any SPC to fund any Loan, and (B) if an SPC elects not to exercise such
option or otherwise fails to fund all or any part of such Loan, the Granting
Lender shall be obligated to fund such Loan pursuant to the terms hereof.
Further, (A) all credit decisions relating to any such funding by the SPC shall
be made by the Granting Lender for and on behalf of the SPC, (B) the SPC shall
have no voting rights under any of the Loan Documents and (C) except for the
payment of principal, interest and fees, if any, the Agent and the Documentation
Agents shall be entitled to treat the Granting Lender as the Lender for all
purposes hereunder as if the SPC had made no funding of any Loan. The funding of
a Loan by an SPC hereunder shall utilize the Revolving Credit Commitment of the
Granting Lender to the same extent, and as if, such Loan were funded by such
Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for
any indemnity or payment under this Agreement for which a Lender would otherwise
be liable for so long as, and to the extent, the Granting Lender provides such
indemnity or makes such payment. Notwithstanding anything to the contrary
contained in this Agreement, any SPC may disclose on a confidential basis any
non-public information relating to its funding of Loans to any rating agency,
commercial paper dealer or provider of any surety or guarantee to such SPC. This
Section may not be amended without the prior written consent of each Granting
Lender, all or any part of whose Loan is being funded by an SPC at the time of
such amendment.

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

                  10.08. Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or enforceability without
invalidating the remaining portions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

                  10.09. Indemnity. The Borrower hereby agrees to indemnify the
Agent, the Documentation Agents, the Lenders, the L/C Issuer, and the directors,
officers, employees,

                                     - 88 -
<PAGE>

attorneys, agents and Affiliates or all of the foregoing (each of the foregoing
an "Indemnified Person") against, and hold each of them harmless from, any loss,
liabilities, damages, claims, costs and expenses (including reasonable
attorneys' fees and disbursements) suffered or incurred by any Indemnified
Person (except those caused by such Indemnified Person's gross negligence or
willful misconduct, ) arising out of, resulting from or in any manner connected
with, the execution, delivery and performance of each of the Loan Documents, the
Lender Obligations and any and all transactions related to or consummated in
connection with the Lender Obligations, including, without limitation, losses,
liabilities, damages, claims, costs and expenses suffered or incurred by any
Indemnified Person arising out of or related to investigating, preparing for,
defending against, or providing evidence, producing documents or taking any
other action in respect of any commenced or threatened litigation,
administrative proceeding or investigation under any Federal securities law or
by any Official Body of any jurisdiction, or at common law or otherwise, that is
alleged to arise out of or is based on (i) any untrue statement or alleged
untrue statement of any material fact of the Borrower or any Affiliate of the
Borrower in any document or schedule filed with the Securities and Exchange
Commission or any other Official Body, (ii) any omission or alleged omission to
state any material fact required to be stated in such document or schedule, or
necessary to make the statements made therein, in light of the circumstances
under which made, not misleading; (iii) any actual or alleged acts, practices or
omissions of the Borrower, any Subsidiary Guarantor, or any of their respective
directors, officers, partners, employees, attorneys, agents or Affiliates,
related to the making of any acquisition, purchase of shares or assets pursuant
thereto, financing of such purchases or the consummation of any other
transactions contemplated by any such acquisitions that are alleged to be in
violation of any Federal securities law or of any other statute, regulation or
other law of any jurisdiction applicable to the making of any such acquisition,
the purchase of shares or assets pursuant thereto, the financing of such
purchases or the consummation of the other transactions contemplated by any such
acquisition; or (iv) any withdrawals, termination or cancellation of any such
proposed acquisition for any reason whatsoever. The indemnity set forth in this
Section 10.9 shall be in addition to any other obligations or liabilities of the
Borrower to the Agent, the Documentation Agents, the Lenders or the L/C Issuer,
or at common law or otherwise. The provisions of this Section 10.9 shall survive
the payment of the Lender Obligations and the termination of this Agreement and
the other Loan Documents.

                  10.10. Confidentiality. The Agent, the Documentation Agents,
the Lenders and the L/C Issuer shall keep confidential and not disclose to any
Person, other than to their respective directors, officers, employees,
Affiliates and agents, and to actual and potential Purchasing Lenders and
Participants, all non-public information concerning the Borrower and the
Borrower's Affiliates which comes into the possession of the Agent, the
Documentation Agents, the Lenders or the L/C Issuer during the term hereof.
Notwithstanding the foregoing, the Agent, the Documentation Agents, the Lenders
and the L/C Issuer may disclose information concerning the Borrower (i) in
accordance-with normal banking practices and the Agent's, such Documentation
Agent's, such Lender's or the L/C Issuer's policies concerning disclosure of
such information in connection with syndication or sales of Participations,
subject to informing the recipient of such information of the duties of
confidentiality hereunder, (ii) pursuant to what the Agent, such Documentation
Agent, such Lender or the L/C Issuer believes to be the lawful requirements or
request of any Official Body regulating banks or banking, (iii) as required by
governmental regulation or rule, judicial process or subpoena; provided however,
if permitted by

                                     - 89 -
<PAGE>

law, the Agent, the Documentation Agents, or such Lender shall notify the
Borrower and permit the Borrower, at the Borrower's cost, to contest such
subpoena; and (iv) to their respective attorneys, accountants and auditors who
have been informed of the confidentiality hereunder.

                  10.11. Survival. All representations, warranties, covenants
and agreements of the Borrower contained herein or in the other Loan Documents
or made in writing in connection herewith shall survive the issuance of the
Notes and the Letters of Credit and shall continue in full force and effect so
long as the Borrower may borrow hereunder and so long thereafter until payment
in full of all the Notes and the Lender Obligations is made. The obligations of
the Borrower under Sections 6.13, 10.02 and 10.03 shall survive the termination
of this Agreement and the discharge of the other obligations of the Borrower
hereunder, and any other Loan Documents, and shall also survive the payment in
full of all Lender Obligations, the termination of the Revolving Credit
Commitment in accordance with the provisions of this Agreement and the
termination or expiration of all Letters of Credit in accordance with their
respective terms.

                  10.12. GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
COMMONWEALTH OF PENNSYLVANIA, WITHOUT REGARD TO THE PRINCIPLES THEREOF REGARDING
CONFLICT OF LAWS, EXCEPTING APPLICABLE FEDERAL LAW AND EXCEPT ONLY TO THE EXTENT
PRECLUDED BY THE MANDATORY APPLICATION OF THE LAW OF ANOTHER JURISDICTION.

                  10.13. FORUM. THE PARTIES HERETO AGREE THAT ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE OTHER LOAN
DOCUMENTS TO WHICH THE BORROWER IS A PARTY MAY BE COMMENCED IN THE COURT OF
COMMON PLEAS OF ALLEGHENY COUNTY, PENNSYLVANIA OR IN THE DISTRICT COURT OF THE
UNITED STATES FOR THE WESTERN DISTRICT OF PENNSYLVANIA, AND THE PARTIES HERETO
AGREE THAT A SUMMONS AND COMPLAINT COMMENCING AN ACTION OR PROCEEDING IN EITHER
OF SUCH COURTS SHALL BE PROPERLY SERVED AND SHALL CONFER PERSONAL JURISDICTION
IF SERVED PERSONALLY OR BY CERTIFIED MAIL TO THE PARTIES AT THEIR ADDRESSES SET
FORTH IN SECTION 10.04, OR AS OTHERWISE PROVIDED UNDER THE LAWS OF THE
COMMONWEALTH OF PENNSYLVANIA. FURTHER, THE BORROWER HEREBY SPECIFICALLY CONSENTS
TO THE PERSONAL JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY,
PENNSYLVANIA AND THE DISTRICT COURT OF THE UNITED STATES FOR THE WESTERN
DISTRICT OF PENNSYLVANIA AND WAIVES AND HEREBY ACKNOWLEDGES THAT IT IS ESTOPPED
FROM RAISING ANY OBJECTION BASED ON FORUM NON CONVENIENS, ANY CLAIM THAT EITHER
SUCH COURT LACKS PROPER VENUE OR ANY OBJECTION THAT EITHER SUCH COURT LACKS
PERSONAL JURISDICTION OVER THE BORROWER SO AS TO PROHIBIT EITHER SUCH COURT FROM
ADJUDICATING ANY ISSUES RAISED IN A COMPLAINT FILED WITH EITHER SUCH COURT
AGAINST THE BORROWER BY THE AGENT, THE DOCUMENTATION AGENTS, THE LENDERS OR THE
L/C ISSUER CONCERNING THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR PAYMENT TO
THE LENDERS. THE BORROWER HEREBY ACKNOWLEDGES AND

                                     - 90 -
<PAGE>

AGREES THAT THE CHOICE OF FORUM CONTAINED IN THIS SECTION 10.13 SHALL NOT BE
DEEMED TO PRECLUDE THE ENFORCEMENT OF ANY JUDGMENT OBTAINED IN ANY FORUM OR THE
TAKING OF ANY ACTION UNDER THE LOAN DOCUMENTS TO ENFORCE THE SAME IN ANY
APPROPRIATE JURISDICTION.

                  10.14. Non-Business Days. Whenever any payment hereunder or
under the Notes is due and payable on a day which is not a Business Day, such
payment may be made on the next succeeding Business Day, and such extension of
time shall in each such case be included in computing interest in connection
with such payment.

                  10.15. Integration. This Agreement and the other Loan
Documents constitute the entire agreement between the parties relating to this
financing transaction and they supersede all prior understandings and
agreements, whether written or oral, between the parties hereto relating to the
transactions provided for herein.

                  10.16. Counterparts. This Agreement and any amendment hereto
may be executed in several counterparts and by each party on a separate
counterpart, each of which, when so executed and delivered, shall be an
original, but all of which together shall constitute but one and the same
instrument. In proving this Agreement, it shall not be necessary to produce or
account for more than one such counterpart signed by the other party against
whom enforcement is sought. Delivery of an executed counterpart of a signature
page to this Agreement by telecopier shall be as effective as delivery of a
manually executed counterpart of this Agreement.

                  10.17. Funding by Branch, Subsidiary or Affiliate.

                           (a) Notional Funding. Each Lender shall have the
right from time to time, without notice to the Borrower, to deem any branch,
subsidiary or affiliate (which for the purposes of this Section 10.17 shall mean
any corporation or association which is directly or indirectly controlled by or
is under direct or indirect common control with any corporation or association
which directly or indirectly controls such Lender) of such Lender to have made,
maintained or funded any Revolving Credit Loan to which the Euro-Rate Option
applies at any time, provided that immediately following (on the assumption that
a payment were then due from the Borrower to such other office) and as a result
of such change the Borrower would not be under any greater financial obligation
to such Lender hereunder, pursuant to Section 2.08, 2.10, 2.11 or 2.12 hereof
than it would have been in the absence of such change. Notional funding offices
may be selected by each Lender without regard to a Lender's actual methods of
making, maintaining or funding the Revolving Credit Loans or any sources of
funding actually used by or available to such Lender.

                           (b) Actual Funding. Each Lender shall have the right
from time to time to make or maintain any Revolving Credit Loan by arranging for
a branch, subsidiary or affiliate of such Lender to make or maintain such
Revolving Credit Loan subject to the last sentence of this Section 10.17(b). If
any Lender causes a branch, subsidiary or affiliate to make or maintain any part
of the Revolving Credit Loans hereunder, all terms and conditions of this
Agreement shall, except where the context clearly requires otherwise, be
applicable to such part of the

                                     - 91 -
<PAGE>

Revolving Credit Loans to the same extent as if such Revolving Credit Loans were
made or maintained by such Lender but in no event shall any Lender's use of such
a branch, subsidiary or affiliate to make or maintain any part of the Revolving
Credit Loans hereunder cause such Lender or such branch, subsidiary or affiliate
to incur any cost or expenses payable by the Borrower hereunder or require the
Borrower to pay any other compensation to any such Lender (including, without
limitation, any expenses incurred or payable pursuant to Section 2.08, 2.10,
2.11 or 2.12 hereof) which would otherwise not be incurred.

                  10.18. WAIVER OF JURY TRIAL. THE BORROWER, EACH LENDER, THE
AGENT, THE DOCUMENTATION AGENTS AND THE L/C ISSUER EACH HEREBY WAIVES THE RIGHT
TO TRIAL BY JURY IN ANY COURT AND IN ANY ACTION OR PROCEEDING OF ANY TYPE IN
WHICH THE BORROWER, THE LENDERS, THE AGENT, THE DOCUMENTATION AGENTS, THE L/C
ISSUER OR ANY OF THEIR RESPECTIVE SUCCESSORS OR ASSIGNS IS A PARTY, AS TO ALL
MATTERS AND THINGS ARISING OUT OF THIS AGREEMENT, THE NOTES OR THE OTHER LOAN
DOCUMENTS.
