"B" hereto, drawn by the Borrower to the order of a Lender in the maximum amount
---
of such Lender's Term Commitment. The principal amount actually due and owing to
a Lender at any time with respect to its Term Commitment shall be the then
aggregate unpaid principal amount of the Term Loan made by such Lender as shown
on the Loan Account established and maintained by the Agent in accordance with
Section 2.11. Each Term Note shall be dated the date hereof and shall be
delivered to the Lenders on such date.

2.1Bd     Making the Term Loans. Each Lender shall remit the principal amount of
          ---------------------
its Term Loan to the Agent by 1:00 p.m. (eastern time) on the Closing Date 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 Term Loans to the
Borrower or to the Borrower's account in Dollars and immediately available funds
at the principal office of the Agent in Pittsburgh, Pennsylvania by 3:00 p.m.
(eastern time) on the Closing Date, provided that if any Lender fails to remit
such funds to the Agent in a timely manner, or any Lender fails to advise the
Agent of its intention not to fund, then the Agent may elect in its sole
discretion to fund with its own funds the Loan of such Lender on the Borrowing
Date, subject to the provisions of Section 8.3 below. The Term Loans shall
initially bear interest at the Base Rate Option.

2.2       Interest Rates, Interest Payment and Certain Provisions Relating to
          -------------------------------------------------------------------
Interest and Fees.
------------------

2.2a      Payments of Interest. The Borrower shall pay interest on the principal
          --------------------
amount of the Loans from time to time outstanding hereunder, from the date
thereof until payment in full, at the rates of interest determined pursuant to
this Section 2.2. The Borrower shall pay accrued interest on the unpaid
principal balance of the Loans in arrears: (i) with respect to each Base Rate
Portion, at the Base Rate on the last day of each Fiscal Quarter during the term

                                      -20-
<PAGE>

thereof; (ii) with respect to each Euro-Rate Portion, at the Adjusted Euro-Rate
on the last day of each Interest Period as provided for in Subsection 2.3c
(provided, however, if the Interest Period chosen for a Euro-Rate Portion
exceeds three (3) months, interest on that Euro-Rate Portion shall be due and
payable on the day which is (A) three months after the first day of such
Interest Period and (B) the last day of such Interest Period); and (iii) with
respect to all such Portions, at the applicable interest rate (A) when due, at
maturity, whether by acceleration or otherwise, and (B) after maturity, on
demand until paid in full.

2.2b      Interest Rate Options. The unpaid principal amount of the Loans shall
          ---------------------
bear interest, for each day until due, at one or more rates of interest selected
by the Borrower from among the Options set forth below; it being understood
that, subject to the provisions of this Agreement, the Borrower may select
different Options to apply simultaneously to different Portions of the Loans and
may select different Interest Periods to apply simultaneously to different
Portions of the Euro-Rate Portions of the Loans.

          (i)  Base Rate Option: A rate of interest per annum (computed upon the
               ----------------
     basis of a year of 365 or 366 days, as the case may be, and the actual
     number of days elapsed) equal to the Base Rate. The rate of interest per
     annum under the Base Rate Option shall be adjusted automatically, from time
     to time, upon each change in the Base Rate.

          (ii) Euro-Rate Option: A rate of interest per annum (computed on the
               ----------------
     basis of a year of 360 days and the actual number of days elapsed) equal to
     the sum of (A) the Euro-Rate plus (B) the Applicable Euro-Rate Margin from
                                  ----
     time to time in effect (the "Adjusted Euro-Rate"). The Adjusted Euro-Rate
     for each Euro-Rate Portion then outstanding shall be adjusted
     automatically, from time to time, effective upon each change in the
     Applicable Euro-Rate Margin resulting from an increase or decrease in the
     Borrower's ratio of Consolidated Total Indebtedness to Consolidated EBITDA.

2.2c      Interest Periods; Limitations on Elections. At any time when the
          ------------------------------------------
Borrower shall select, convert to or renew at the Euro-Rate Option with respect
to all or any Portion of the outstanding Loans, it shall fix one or more
Interest Periods during which such Option(s) shall apply. All of the foregoing,
however, is subject to the following:

          (i)  any 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
     Business Day falls in the succeeding calendar month in which case such
     Interest Period shall end on the next preceding Business Day; and

          (ii) any 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 Interest Period is to end
     shall end on the last Business Day of such subsequent month.

     In addition, elections by the Borrower of the Euro-Rate Option shall be
subject to the following further limitations:

                                      -21-
<PAGE>

          (i)   The Euro-Rate Portions for each Interest Period shall be in
     integral multiples of $1,000,000 and not less than $3,000,000;

          (ii)  (x) If an Interest Period is elected with regard to amounts
     outstanding under the Revolving Credit Commitments and such Interest Period
     would end after the Termination Date, such Interest Period shall end on the
     Termination Date, and (y) if an Interest Period is elected with regard the
     amounts outstanding under the Term Commitments and such Interest Period
     would end after the Maturity Date, such Interest Period shall end on the
     Maturity Date; and

          (iii) At no time may there be more than six (6) Interest Periods in
     effect relating to Loans; provided, however if a Base Rate Portion is
     outstanding there shall be not more than five (5) Interest Periods in
     effect relating to Loans.

2.2d      Election, Conversion or Renewal of Interest Rate Options. Elections of
          --------------------------------------------------------
or conversions to the Base Rate Option shall continue in effect until converted
to the Euro-Rate Option as hereinafter provided. Elections of, conversions to or
renewals of the Euro-Rate Option shall expire as to each Euro-Rate Portion at
the expiration of the applicable Interest Period.

          At any time, with respect to any Base Rate Portion, or at the
expiration of the applicable Interest Period, with respect to any Euro-Rate
Portion, the Borrower (subject to Subsection 2.2c) may cause all or any part of
the principal amount of such Portion to be converted to and/or (in the case of a
Euro-Rate Portion) to be renewed under the Euro-Rate Option by notice to each of
the Lenders as hereinafter provided. Such notice (i) shall be irrevocable; (ii)
shall be given not later than 11:00 A.M. (eastern time) in the case of a
conversion to or renewal of, either in whole or in part, the Euro-Rate Option on
the third Business Day prior to the proposed effective date for the 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 Interest Period(s) selected; and

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

          At the expiration of each 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 as provided above,
shall automatically be converted to the Base Rate Option.

2.2e      Notification of Election of an Interest Rate Option. Any communication
          ---------------------------------------------------
under Subsection 2.1Ad, 2.2b or 2.2d may be oral or written and if oral, it
shall be followed immediately by written confirmation of such Option election
executed by an Authorized Officer.

                                      -22-
<PAGE>

2.2f      Interest After Default. Upon the occurrence of an Event of Default,
          ----------------------
and during the continuance of such Event of Default, or after the principal
amount of all or any part of the Base Rate Portions of the Loans shall have
become due and payable, whether by acceleration or otherwise and whether or not
judgment has been entered against the Borrower thereon, all Base Rate Portions
shall bear interest at a rate per annum which shall be two hundred (200) basis
points (2%) per annum above the rate otherwise in effect under the Base Rate
Option, such interest rate to change automatically from time to time, effective
as of the effective date of each change in the Base Rate. Upon the occurrence of
an Event of Default, and during the continuance of such Event of Default, or
after the principal amount of all or any part of the Euro-Rate Portions of the
Loans shall have become due and payable, whether by acceleration or otherwise
and whether or not judgment has been entered against the Borrower thereon, all
such Euro-Rate Portions shall bear interest (i) until the end of the then
current Interest Period, at a rate per annum which shall be two hundred (200)
basis points (2%) per annum above the rate otherwise in effect under the Euro-
Rate Option, and (ii) at the end of the then current Interest Period, and
thereafter at the sum of (A) the Base Rate plus (B) two hundred (200) basis
                                           ----
points (2%) per annum.

2.3       Yield-Protection, Capital Adequacy and Miscellaneous Provisions
          ---------------------------------------------------------------
Relating to Euro-Rate.
---------------------

2.3a      Yield Protection. Notwithstanding other provisions of this Section
          ----------------
2.3:

          (i)  With respect to any Lender, if any Governmental Rule, or if any
     change therein on or after the date hereof, or in the interpretation
     thereof by any Governmental Authority charged with the administration
     thereof, shall:

               (A) subject such Lender to any tax, levy, impost, charge, fee,
     duty, deduction or withholding of any kind with respect to payments of
     principal or interest or other amounts due hereunder (other than any tax
     imposed or based upon the income, gross receipts or capital or franchise
     taxes of such Lender and payable to any Governmental Authority in the
     United States of America or any state thereof and other than taxes due by a
     failure of such Lender to comply with Section 9.4); or

               (B) change the basis of taxation of such 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 or any state thereof of the total net income
     of such Lender); or

               (C) impose, modify or deem applicable any reserve, special
     deposit or similar requirements against assets held by such Lender
     applicable to its Commitment or Loans made hereunder (other than such
     requirements which are included in the determination of the applicable rate
     of interest hereunder); or

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

                                      -23-
<PAGE>

     and the result of any of the foregoing is to increase the cost to the
     affected Lender, reduce the income receivable by the affected Lender,
     reduce the rate of return on the affected Lender's capital, or impose any
     expenses upon the affected Lender, all with respect to any of the Loans (or
     any portion thereof) by an amount which the affected Lender reasonably
     deems material, and if the affected Lender is then demanding similar
     compensation for such occurrences from other borrowers who are similarly
     situated and who have a similar relationship with the affected Lender and
     from which the affected Lender has the right to demand such compensation,
     then and in any such case:

               (1) the affected Lender shall promptly notify the Borrower of the
          happening of such event;

               (2) the Borrower shall pay to the affected Lender, on demand,
          such amount as will compensate the affected Lender for such reduction
          in its rate of return; and

               (3) the Borrower may pay the affected portion of the affected
          Lender's Loans in full without the payment of any additional amount,
          including prepayment penalties, other than amounts payable on account
          of the affected Lender's out-of-pocket losses (including funding loss,
          if any, as provided in Section 2.9) which are not otherwise provided
          for in subparagraph (2) immediately above.

          (ii) A certificate as to the increased cost or reduced amount as a
     result of any event mentioned in this Subsection 2.3a shall be promptly
     submitted by the affected Lender to the Borrower in accordance with the
     provisions hereof. Such certificate shall be prima facie evidence as to the
     amount of such increased cost or reduced amount.

2.3b      Capital Adequacy. If, after the date hereof, (i) any adoption of or
          ----------------
any change in or in the interpretation of any Governmental Rule, or (ii)
compliance with any Governmental Rule of any Governmental Authority exercising
control over banks or financial institutions generally or any court of competent
jurisdiction, requires that the Commitment (including, without limitation,
obligations in respect of any Loans) hereunder be treated as an asset or
otherwise be included for purposes of calculating the appropriate amount of
capital to be maintained by any Lender or any corporation controlling any Lender
(a "Capital Adequacy Event"), the result of which is to reduce the rate of
return on a Lender's capital as a consequence of its Commitment to a level below
that which the affected Lender could have achieved but for such Capital Adequacy
Event, taking into consideration the Lender's policies with respect to capital
adequacy, by an amount which the affected Lender reasonably deems to be
material, the affected Lender shall promptly deliver to the Borrower a statement
of the amount necessary to compensate the affected Lender or the reduction in
the rate of return on its capital attributable to its Commitment (the "Capital
Compensation Amount"). The affected Lender shall determine the Capital
Compensation Amount in good faith, using reasonable attribution and averaging
methods. Each affected Lender shall from time to time notify the Borrower of the
amount so determined. Each such notification shall be prima facie evidence of
the amount of the Capital Compensation Amount set forth therein, and such
Capital Compensation Amount shall be due

                                      -24-
<PAGE>

and payable by the Borrower to the affected Lender thirty (30) days after such
notice is given. As soon as practicable after any Capital Adequacy Event, the
affected Lender shall submit to the Borrower estimates of the Capital
Compensation Amounts that would be payable as a function of the affected
Lender's Commitment hereunder.

2.3c      Euro-Rate Unascertainable. If, on any date on which the Adjusted Euro-
          -------------------------
Rate would otherwise be set, the Agent reasonably shall have determined (which
determination shall be final and conclusive) that by reason of circumstances
affecting the interbank Eurodollar market, adequate and reasonable means do not
exist for ascertaining the Euro-Rate, the Agent shall give prompt notice of such
determination to the Borrower and the Lenders and, until the Agent notifies the
Borrower and the Lenders that the circumstances giving rise to such
determination no longer exist, the right of the Borrower to borrow under,
convert to or renew the Euro-Rate Option shall be suspended with respect to any
period for which the Euro-Rate is not ascertainable, and with respect to any
such period, 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 at
the Base Rate Option with respect to the principal amount therein specified.

2.3d      Illegality. If a Lender shall determine in good faith (which
          ----------
determination shall be final and conclusive) that compliance by such Lender with
any applicable law, treaty or other Governmental Rule (whether or not having the
force of law), or the interpretation or application thereof by any Governmental
Authority, has made it unlawful for such Lender to make or maintain the Loans
under the Euro-Rate Option (including but not limited to acquiring Eurodollar
liabilities to fund such Loans), such Lender shall give notice of such
determination to the Borrower and the other Lenders. Notwithstanding any
provision of this Agreement to the contrary, unless and until the affected
Lender shall have given notice to the Borrower and the other Lenders that the
circumstances giving rise to such determination no longer apply:

          (i)  with respect to any Interest Periods thereafter commencing,
     interest on the Loans bearing interest at the Adjusted Euro-Rate (whichever
     one or more have been determined by the affected Lender to be unlawful)
     shall, unless the Borrower shall have selected a different Option which is
     then available, be computed and payable under the Base Rate Option; and

          (ii) on such date, if any, as shall be required by law, any Loans
     bearing interest at the Adjusted Euro-Rate then outstanding shall be
     automatically converted to the Base Rate Option, and the Borrower shall pay
     to the affected Lender the accrued and unpaid interest on such Loans to
     (but not including) the date of such conversion at the applicable interest
     rate or rates in effect for such Loans prior to such conversion.

2.4       Fees.
          ----

2.4a      Closing Fee. The Borrower agrees to pay to the Lenders, on or before
          -----------
the Closing Date, a Closing Fee, in such amounts as agreed upon between the
Borrower and each Lender.

                                      -25-
<PAGE>

2.4b      Commitment Fee. The Borrower agrees to pay to the Agent on behalf of
          --------------
the Lenders, on a pro rata basis, beginning on December 31, 2001, and continuing
quarterly in arrears thereafter on the last day of each March, June, September
and December during the term hereof to and including the Termination Date, a
Commitment Fee calculated at a rate per annum equal to the Commitment Fee Rate
on the average daily unused portion of the Revolving Credit Commitment for the
quarter then ending; provided, however, the first payment under this Subsection
                     --------
2.4b shall be only for the actual number of days elapsed between the Closing
Date and December 31, 2001, and the last payment under this Subsection 2.4b
shall be only for the actual number of days elapsed between the last quarterly
payment date and the Termination Date. If there is any change in the Commitment
Fee Rate during the quarter, the Commitment Fee shall be calculated with respect
to each period that the Commitment Fee Rate was in effect during such quarter.

2.4c      Agent's Fee. The Borrower agrees to pay to the Agent for its own
          -----------
account the non-refundable Agent's Fees for the Agent's services hereunder under
the terms of that certain letter (the "Agent's Letter") between the Borrower and
Agent dated July 2, 2001, as the same may be amended from time to time.

2.4d      Letter of Credit Fee and Fronting Fee. The Borrower shall pay to the
          -------------------------------------
Agent, from time to time, for the benefit of the Lenders, the Letter of Credit
Fee as set forth in Subsection 2.6b. The Borrower shall pay to the Agent, from
time to time, for its sole account, the Fronting Fee as set forth in Subsection
2.6b.

2.5       Calculation of Interest and Certain Fees. The calculation of the
          ----------------------------------------
amount of interest due and owing to each Lender shall be made by the Agent and
shall be evidenced by the Agent posting the amount of interest due under such
Lender's Loans to the Loan Account established pursuant to Section 2.11. The
Commitment Fee shall be calculated on the basis of a 360 day year and actual
number of days elapsed. The calculation of the amount of the Commitment Fee due
and owing to each Lender shall be made by the Agent and shall be evidenced by
posting such amount due under the Loan Account established pursuant to Section
2.11.

2.6       Letter of Credit Sub-Facility.
          -----------------------------

2.6a      Issuance of Letters of Credit. The Borrower may request the issuance
          -----------------------------
of a letter of credit (each a "Letter of Credit") by delivering to the Agent a
completed application and agreement for letters of credit in such form as the
Agent may specify from time to time by no later than 10:00 A.M., Pittsburgh,
Pennsylvania time, at least five (5) business Days, or such shorter period as
may be agreed to by the Agent, in advance of the proposed date of issuance. Each
Letter of Credit shall be denominated in Dollars. Subject to the terms and
conditions hereof and in reliance on the agreements of the other Lenders set
forth in this Section 2.6, the Agent will issue a Letter of Credit provided that
each Letter of Credit shall (A) have a maximum maturity of one year from the
date of issuance, and (B) in no event expire later than ten (10) Business Days
prior to the Termination Date and providing that in no event shall the aggregate
amount of Letters of Credit Outstanding exceed, at any one time, $2,000,000. The
amount of Letters of Credit Outstanding at any time shall reduce the maximum
amount otherwise available

                                      -26-
<PAGE>

for Revolving Credit Loans under the Revolving Credit Commitments. No Letters of
Credit may be issued hereunder to the extent that such issuance would cause the
sum of (i) the Letters of Credit Outstanding plus (ii) the aggregate amount of
                                             ----
Revolving Credit Loans outstanding to exceed the aggregate amount of Revolving
Credit Commitments then in effect.

2.6b      Letter of Credit Fees. The Borrower shall pay to the Agent for the
          ---------------------
ratable account of the Lenders a fee (the "Letter of Credit Fee") equal to the
Applicable Euro-Rate Margin for Loans other than Secured Loans (computed on the
basis of a year of 360 days and actual days elapsed), which fees shall be
computed on the daily average amount of the Letters of Credit Outstanding and
shall be payable quarterly in arrears commencing with the last Business Day of
each March, June, September and December following issuance of each Letter of
Credit. The Borrower shall also pay to the Agent for the Agent's sole account
(i) one-eighth of one percent (.125%) per annum of the amount of any Letters of
Credit Outstanding (the "Fronting Fee") quarterly in arrears, and (ii) as
incurred the Agent's then current customary fees and administrative expenses
payable with respect to the Letters of Credit as the Agent may generally charge
or incur from time to time in connection with the issuance, maintenance,
modification (if any), assignment or transfer (if any), negotiation, and
administration of Letters of Credit.

2.6c      Letter of Credit Fees Upon Default. (A) Upon the occurrence of an
          ----------------------------------
Event of Default, and during the continuance of such Event of Default, or (B)
upon the acceleration of the Bank Indebtedness for any reason hereunder, the
Letter of Credit Fee shall be automatically increased by two percent (2%) in
excess of the applicable Letter of Credit Fee then in effect.

2.6d      Disbursements, Reimbursement.
          ----------------------------

          (A) Immediately upon the issuance of each Letter of Credit, each
Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase from the Agent a participation in such Letter of Credit and each
drawing thereunder in an amount equal to such Lender's Ratable Share of the
maximum amount available to be drawn under such Letter of Credit and the amount
of such drawing, respectively.

          (B) In the event of any request for a drawing under a Letter of Credit
by the beneficiary or transferee thereof, the Agent will promptly notify the
Borrower of the amount of such drawing and the date such payment shall be made.
The Borrower shall reimburse (such obligation to reimburse the Agent shall
sometimes be referred to as a "Reimbursement Obligation") the Agent for any
amount paid by the Agent under any Letter of Credit (each such date of a payment
by the Agent under a Letter of Credit, a "Drawing Date") in an amount equal to
the amount so paid by the Agent. Such Reimbursement Obligation shall be paid
prior to 12:00 noon, Pittsburgh, Pennsylvania time, on the Drawing Date. In the
event the Borrower fails to reimburse the Agent for the full amount of any
drawing under any Letter of Credit by 12:00 noon, Pittsburgh, Pennsylvania time,
on the Drawing Date, the Agent will promptly notify each Lender thereof, and the
Borrower shall be deemed to have requested that Revolving Credit Loans be made
by the Lenders under the Base Rate Option to be disbursed on the Drawing Date
under such Letter of Credit, subject to the amount of the unutilized portion of
the Commitments (without giving effect to outstanding Letters of Credit) and
subject to the conditions set forth in Section 6.1 other than any notice
requirements. Any notice given by the Agent pursuant to this

                                      -27-
<PAGE>

Subsection 2.6d(B) may be oral if immediately confirmed in writing; provided
                                                                    --------
that the lack of such an immediate confirmation shall not affect the
conclusiveness or binding effect of such notice.

          (C) Each Lender shall upon any notice pursuant to Subsection 2.6d(B)
make available to the Agent an amount in immediately available funds equal to
its Ratable Share of the amount of the drawing, whereupon the participating
Lenders shall (subject to Subsection 2.6d(D)) each be deemed to have made a
Revolving Credit Loan under the Base Rate Option to the Borrower in that amount.
If any Lender so notified fails to make available to the Agent for the account
of the Agent the amount of such Lender's Ratable Share of such amount by no
later than 2:00 P.M., Pittsburgh, Pennsylvania time on the Drawing Date, then
interest shall accrue on such Lender's obligation to make such payment, from the
Drawing Date to the date on which such Lender makes such payment (i) at a rate
per annum equal to the Federal Funds Effective Rate during the first three days
following the Drawing Date and (ii) at a rate per annum equal to the rate
applicable to Revolving Credit Loans under the Base Rate Option on and after the
fourth day following the Drawing Date. The Agent will promptly give notice of
the occurrence of the Drawing Date to each Lender, but failure of the Agent to
give any such notice on the Drawing Date or in sufficient time to enable any
Lender to effect such payment on such date shall not relieve such Lender from
its obligation under this Subsection 2.6d(C).

          (D) With respect to any unreimbursed drawing that is not converted
into Revolving Credit Loans under the Base Rate Option to the Borrower in whole
or in part as contemplated by Subsection 2.6d(B), because of the Borrower's
failure to satisfy the conditions set forth in Section 6.1 other than any notice
requirements or for any other reason, the Borrower shall be deemed to have
incurred from the Agent a Letter of Credit Borrowing in the amount of such
drawing. Such Letter of Credit Borrowing shall be due and payable on demand
(together with interest) and shall bear interest at the rate per annum
applicable to the Revolving Credit Loans under the Base Rate Option as adjusted
to reflect the default rate provisions set forth in Subsection 2.2f. Each
Lender's payment to the Agent pursuant to Subsection 2.6d(C) shall be deemed to
be a payment in respect of its participation in such Letter of Credit Borrowing
and shall constitute a Participation Advance from such Lender in satisfaction of
its participation obligation under this Subsection 2.6d. The provisions of this
Subsection (D) are solely for the benefit of the Agent, as issuer of the Letters
of Credit, and shall not be deemed to excuse, waive or consent to an Event of
Default under Section 7.1 arising from an unreimbursed drawing giving rise to a
Participation Advance.

2.6e      Repayment of Participation Advances.
          -----------------------------------

          (A) Upon (and only upon) receipt by the Agent for its account of
immediately available funds from the Borrower (i) in reimbursement of any
payment made by the Agent under the Letter of Credit with respect to which any
Lender has made a Participation Advance to the Agent, or (ii) in payment of
interest on such a payment made by the Agent under such a Letter of Credit, the
Agent will pay to each Lender, in the same funds as those received by the Agent,
the amount of such Bank's Ratable Share of such funds, except the Agent shall
retain the amount of the Ratable Share of such funds of any Lender that did not
make a Participation Advance in respect of such payment by Agent.

                                      -28-
<PAGE>

          (B) If the Agent is required at any time to return to the Borrower, or
to a trustee, receiver, liquidator, custodian, or any official in any proceeding
described in Section 7.3, any portion of the payments made by the Borrower to
the Agent pursuant to Subsection 2.6d(B) in reimbursement of a payment made
under the Letter of Credit or interest or fee thereon, each Lender shall, on
demand of the Agent, forthwith return to the Agent the amount of its Ratable
Share of any amounts so returned by the Agent plus interest thereon from the
date such demand is made to the date such amounts are returned by such Lender to
the Agent, at a rate per annum equal to the Federal Funds Effective Rate in
effect from time to time.

2.6f      Documentation. The Borrower agrees to be bound by the terms of the
          -------------
Agent's application and agreement for letters of credit and the Agent's written
regulations and customary practices relating to letters of credit, though such
interpretation may be different from the Borrower's own. In the event of a
conflict between such application or agreement and this Agreement, this
Agreement shall govern. It is understood and agreed that, except in the case of
gross negligence or willful misconduct, the Agent shall not be liable for any
error and/or mistakes, whether of omission or commission, in following the
Borrower's instructions or those contained in the Letters of Credit or any
modifications, amendments or supplements thereto.

2.6g      Determinations to Honor Drawing Requests. In determining whether to
          ----------------------------------------
honor any request for drawing under any Letter of Credit by the beneficiary
thereof, the Agent shall be responsible only to determine that the documents and
certificates required to be delivered under such Letter of Credit have been
delivered and that they comply on their face with the requirements of such
Letter of Credit.

2.6h      Nature of Participation and Reimbursement Obligations. Each Lender's

or Participation Advances, as contemplated by Subsection 2.6d, as a result of a
drawing under a Letter of Credit, and the obligation of the Borrower to
reimburse the Agent upon a draw under a Letter of Credit, shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Section 2.6 under all circumstances, including the
following circumstances:

     for the making of a Revolving Credit Loan, it being acknowledged that such
     conditions are not required for the making of a Letter of Credit Borrowing
     and the obligation of the Lenders to make Participation Advances under
     Subsection 2.6d; provided, however the aggregate amount thereof shall in no
     event exceed the unutilized Revolving Credit Commitments;

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

                                      -29-
<PAGE>

          (iv)   the existence of any claim, set-off, defense or other right
     which the Borrower or any Lender may have at any time against a beneficiary
     or any transferee of any Letter of Credit (or any Persons for whom any such
     transferee may be acting), the Agent or any Lender or any other Person or,
     whether in connection with this Agreement, the transactions contemplated
     herein or any unrelated transaction (including any underlying transaction
     between the Borrower and the beneficiary for which any Letter of Credit was
     procured);

          (v)    any draft, demand, certificate or other document presented
     under any Letter of Credit proving to be forged, fraudulent, invalid or
     insufficient in any respect or any statement therein being untrue or
     inaccurate in any respect even if the Agent has been notified thereof;

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

          (vii)  any adverse change in the business, operations, properties,
     assets, condition (financial or otherwise) or prospects of the Borrower;

          (viii) any breach of this Agreement or any other Loan Document by any
     party thereto;

          (ix)   the occurrence or continuance of any proceeding described in
     Section 7.3 with respect to the Borrower;

          (x)    the fact that an Event of Default shall have occurred and be
     continuing;

     similar to any of the foregoing.

          ---------
the Borrower hereby agrees to protect, indemnify, pay and save harmless the
Agent from and against any and all claims, demands, liabilities, damages,
losses, costs, charges and expenses (including reasonable fees, expenses and
disbursements of counsel and allocated costs of internal counsel) which the
Agent may incur or be subject to as a consequence, direct or indirect, of (i)
the issuance of any Letter of Credit, other than as a result of (A) gross
negligence or willful misconduct of the Agent as determined by a final judgment
of a court of competent jurisdiction or (B) subject to the following clause
(ii), the wrongful dishonor by the Agent of a proper demand for payment made
under any Letter of Credit, or (ii) the failure of the Agent to honor a drawing
under any such Letter of Credit as a result of any act or omission, whether
rightful or

                                      -30-
<PAGE>

wrongful, of any present or future de jure or de facto Governmental Authority
(all such acts or omissions herein called "Governmental Acts").

2.6j Liability for Acts and Omissions. As between the Borrower and the Agent,
     --------------------------------
the Borrower assumes all risks of the acts and omission of, or misuse of the
Letters of Credit by, the respective beneficiaries of such Letters of Credit. In
furtherance and not in limitation of the foregoing, the Agent shall not be
responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or
legal effect of any document submitted by any party in connection with the
application for an issuance of any such Letter of Credit, even if it should in
fact prove to be in any or all respects invalid, insufficient, inaccurate,
fraudulent or forged; (ii) the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign any such Letter of
Credit or the rights or benefits thereunder or proceeds thereof, in whole or in
part, which may prove to be invalid or ineffective for any reason; (iii) the
failure of the beneficiary of any such Letter of Credit, or any other party to
which such Letter of Credit may be transferred, to comply fully with any
conditions required in order to draw upon such Letter of Credit so long as the
documents presented in connection with such draw appear on their face to
substantially comply with the terms and conditions of the relevant Letter of
Credit; (iv) any claim of the Borrower against any beneficiary of any such
Letter of Credit, or any transferee of such Letter of Credit, or any dispute
between or among the Borrower and any beneficiary of any Letter of Credit or any
such transferee; (v) errors, omissions, interruptions or delays in transmission
or delivery of any messages, by mail, cable, telegraph, telex or otherwise,
whether or not they be in cipher; (vi) errors in interpretation of technical
terms; (vii) any loss or delay in the transmission or otherwise of any document
required in order to make a drawing under any such Letter of Credit or of the
proceeds thereof; (viii) the misapplication by the beneficiary of any such
Letter of Credit of the proceeds of any drawing under such Letter of Credit; or
(ix) any consequences arising from causes beyond the control of the Agent,
including any Governmental Acts, and none of the above shall affect or impair,
or prevent the vesting of, any of the Agent's rights or powers hereunder.
Nothing in the preceding sentence shall relieve the Agent from liability for the
Agent's gross negligence or willful misconduct in connection with actions or
omissions described in such clauses (i) through (viii) of such sentence.

2.6k Uniform Customs. Except and to the extent inconsistent with the specific
     ---------------

    ---------------------------------------
(provided that at such time, no Event of Default and no Potential Default has
occurred and is continuing), in its sole discretion, to either:

                                     -31-
<PAGE>

          (i)   repay, (A) at any time if either no Loans are outstanding or if
     Loans bearing interest under the Base Rate Option are the only Loans
     outstanding, (B) subject to Section 2.9, upon three (3) days prior notice
     if the Loans outstanding include Loans bearing interest under the Euro-Rate
     Option, the outstanding Loans of any Lender in whole, together with
     interest thereon and any other amount due such Lender pursuant to the terms
     of this Agreement, and to terminate the Commitment of such Lender; or

          (ii)  seek a substitute lending institution or institutions (which may
     be one or more of the other Lenders) to purchase the Notes and assume the
     Loans, the Commitment and the other obligations of such Lender under this
     Agreement,

if any of the following conditions occur with respect to such Lender:

          (i)   such Lender shall have delivered a notice or certificate
     pursuant to Subsection 2.3a or 2.3b;

          (ii)  the obligation of such Lender to make or renew Loans which bear
     or are to bear interest under the Euro-Rate Option has been suspended
     pursuant to Subsection 2.3d; or

          (iii) such Lender shall have defaulted under Section 9.4 or failed to
     fund a Disbursement.

          Provided, any proposed substitute lending institution, which is not a
          --------
Lender prior to the Borrower's selection thereof, must be acceptable to the
Agent, whose consent shall not be unreasonably withheld or delayed, and
provided, further that all of the provisions of Section 9.6 (with respect to any
--------  -------
Lender) and Section 8.11 (if the affected Lender is the Agent) must be complied
with.

2.8  Loan Repayment and Prepayment.
     -----------------------------

2.8a Voluntary Prepayments. Each repayment of the Loans shall be in the minimum
     ---------------------
amount of [$1,000,000], in the aggregate, or an integral multiple of $100,000
thereof, or such lesser amount as is actually outstanding thereunder. The
Borrower, upon (i) oral or written notice to Agent by 11:00 A.M. (eastern time)
on the day of the proposed repayment, in the case of Loans bearing interest at
the Base Rate or (ii) three (3) Business Days' prior oral or written notice to
the Agent, in the case of Loans bearing interest at the Adjusted Euro-Rate,
followed immediately thereafter by the Borrower's written confirmation to the
Agent of any oral notice, may repay the outstanding amount of the Loans in whole
or in part with accrued interest, fees and other amounts then due and payable on
the amount repaid to the date of such repayment, subject to the payment of any
additional amounts under Section 2.9 below. The Borrower may prepay any Portion
of the Loans without premium or penalty subject to Section 2.9. The Borrower
shall notify the Agent whether any such repayment of Revolving Credit Loans
applies to General Revolving Loans or Distribution Loans. If no such notice is
given, such repayment shall be deemed to be first a repayment of Distribution
                                            -----
Loans, and second a repayment of General Revolving Loans.
           ------
                                     -32-
<PAGE>

      Any repayment of the Revolving Credit Loans shall increase, by the amount
of that repayment, the unborrowed balance of the Revolving Credit Commitments;
it being contemplated that the Borrower may repay and reborrow from time-to-time
under the Revolving Credit Commitments until the Termination Date.

2.8b  Scheduled Repayment. All Revolving Credit Loans outstanding on the
      -------------------
Termination Date shall become due and payable in full on such date. All Term
Loans outstanding on the Maturity Date shall become due and payable in full on
such date.

2.9   Additional Payments by the Borrower. If (i) the Borrower shall fail to
      -----------------------------------
make any payment due hereunder on the due date thereof, (ii) the Borrower shall
make a payment, prepayment or conversion of any Euro-Rate Portion of the Loans
on a day other than the last day of the applicable Interest Period, or (iii) the
Borrower shall fail on the date specified therefor to consummate any borrowing,
conversion or renewal after giving a request for a Disbursement or notice of
conversion or renewal, and, as a result of any such action or inaction, a Lender
reasonably incurs any losses and expenses which it would not have incurred but
for such action or inaction, the Borrower shall pay such additional amounts as
will compensate the affected Lender for such losses and expenses, including the
cost of reemployment of any funds prepaid at rates lower than the cost to the
affected Lender of such funds. Such losses and expenses, which the affected
Lender shall exercise reasonable efforts to minimize, shall be specified in
writing (setting forth, in reasonable detail, the basis of calculation) to the
Borrower by the affected Lender, which writing shall be prima facie evidence of
the amounts set forth therein, and such amounts shall be payable within thirty
(30) days of demand therefor.

2.10  Changes of Commitments.
      ----------------------

2.10a Voluntary Reduction of Availability. At any time and from time to time
      -----------------------------------
upon no less than 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 Commitment Fee; provided, however, that the Borrower may not
                                 --------  -------
terminate an unused portion of the Revolving Credit Commitments such that the
aggregate Revolving Credit Commitments are reduced below the Letters of Credit
Outstanding. Each such reduction shall be in a minimum principal amount of
$1,000,000 or in integral multiples thereof. 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.

2.10b Increasing the Revolving Credit Commitments. The Borrower shall have the
      -------------------------------------------
right, with the prior written consent of the Lenders, to cause from time to time
an increase in the aggregate Revolving Credit Commitments of the Lenders by
adding to this Agreement one or more additional Lenders or by allowing one or
more Lenders to increase their respective Revolving Credit Commitments;
provided, however, (i) no Potential Default or Event of Default shall have
--------  -------
occurred hereunder which is continuing, (ii) no Lender's Revolving Credit

                                     -33-
<PAGE>

Commitment shall be increased without such Lender's consent, (iii) such new or
existing Lender acquiring such increase in the Revolving Credit Commitment shall
be required to purchase from each other existing Lender (in accordance with
Section 9.6 below) a portion of each such Lender's Term Loan in such amount as
shall be necessary such that each Lender's pro rata share of the outstanding
Term Loans after giving effect to the increase in the aggregate Revolving Credit
Commitments shall be in proportion to such Lender's Commitment Percentage of the
new Revolving Credit Commitment, and (iv) on the effective date of any such
increase, there shall be no Loans bearing interest at the Adjusted Euro-Rate
outstanding hereunder. In the event of any such increase in the aggregate
Revolving Credit Commitments and in the Revolving Credit Commitment of any
Lender effected pursuant to the terms of this Subsection 2.10b, new Notes shall,
to the extent necessary, be executed and delivered by the Borrower in exchange
for the surrender of the existing Notes, as the case may be, substantially in
the manner provided in Section 9.6.

2.11  Loan Account. The Agent shall open and maintain on its books a Loan
      ------------
Account in the name of the Borrower, with respect to (i) the amounts and types
of Disbursements 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, (iii) the computation and payment of the Fees due hereunder to the
Lenders and the Agent, and (iv) the computation of other amounts due and sums
paid and payable to the Lenders and the Agent hereunder. The Loan Account shall
be prima facie evidence as to the amount at any time due to the Lenders and the
Agent from the Borrower hereunder; provided, however, that the failure to make
                                   --------
notations, or to make accurate notations, on such Loan Account including without
limitation notations with respect to interest and Fees pursuant to Section 2.5
or otherwise shall not limit, expand or otherwise affect any obligations of the
Borrower hereunder.

2.12  Payment from Accounts Maintained by Borrower. In the event that any
      --------------------------------------------
payment of principal, interest, Fees or any other amount due to the Lenders or
the Agent under the Agreement, the Notes or the other Loan Documents is not paid
when due, the Agent is hereby authorized to effect such payment by debiting any
demand deposit account of the Borrower maintained with the Agent (excluding
however any special purpose fiduciary accounts, which are designated as such at
the time of their creation, or mandated by applicable statutes, regulations or
rules) and distributing such payment to the party to whom such amounts are due.
This right of debiting accounts of the Borrower is in addition to any right of
set-off accorded the Lenders or the Agent hereunder or by operation of law.

2.13  Time, Place and Manner of Payments. All payments and prepayments to be
      ----------------------------------
made by the Borrower in respect of principal, interest or other costs relating
to the Loans, Reimbursements Obligations and all Fees and any other amounts due
hereunder (excepting those amounts due under Sections 2.3 and 2.9 hereof) shall
be made at the principal office of the Agent for the ratable account of the
Lenders or the Agent, as the case may be. The Agent will promptly pay each such
payment received to each Lender or its order in accordance with Section 8.9
hereof. All payments due a Lender by reason of Sections 2.3 or 2.9 hereof shall
be paid at the principal office of the Lender which invoices the Borrower for
such payment. All payments to be made by the Borrower under this Agreement shall
be paid in Dollars and in immediately

                                     -34-
<PAGE>

available funds no later than 12:00 noon (eastern time) on the date such payment
is 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. Notwithstanding anything herein to the contrary,
(i) the Agent's Fee, (ii) the Fronting Fee, and (iii) any interest paid with
respect to any Loan or any unreimbursed draw on the Letter of Credit to the
extent a Lender has not been required to honor or has not honored its funding
obligation with respect thereto shall be solely for the account of the Agent.

2.14 Certain Security. (i) To secure the repayment of the Secured Obligations,
     ----------------
the Borrower will execute and deliver to the Agent the Pledge Agreement
substantially in the form of Exhibit "H", together with a duly-executed control
agreement with respect to the securities account described in the Pledge
Agreement and all appropriate Form UCC-1 financing statements.

     (ii)  Prior to the advances of the Term Loan hereunder, the Borrower will
deposit, or cause to be deposited, into a securities account maintained with
___________________ and subject to a first Encumbrance in favor of the Agent
(for the benefit of the Lenders) Qualifying Securities with a value equal to at
least $20,000,000.

     (iii) So long as no Event of Default or Potential Default then exists, the
Borrower may request from time to time that the Agent, with the prior written
consent of all Lenders, release all or a portion of the Qualifying Securities
from the Encumbrance created or purported to be created under the Pledge
Agreement. Each such request shall be made by the Borrower to the Agent in
writing at least thirty (30) days but not more than ninety (90) days prior to
the date when such Qualifying Securities are to be released. The Borrower shall
provide the Agent with any information or documentation that the Agent may
reasonably request in support of the requested release of Qualifying Securities.
The Agent and the Lenders shall use their best efforts to respond to such
request in a timely manner; provided, however, that neither the Agent nor any
Lender shall be liable in any manner for failing to respond to any such request,
such response to be in the sole and absolute discretion of each Lender, and the
failure of the Agent or any Lender to so respond shall be deemed to be a
negative response from the Agent or such Lender, as the case may be. Any
Qualifying Securities released pursuant to this Section 2.14 shall be liquidated
by the Borrower, and the proceeds thereof shall be used by the Borrower solely
for the purposes described in Section 4.1(iv)(x), (y) and (z) below.

           (iv) Notwithstanding the foregoing, so long as no Event of Default or
Potential Default then exists, in the event that (as a result of a prepayment or
otherwise) the then current value (as determined by the Agent) of the Qualifying
Securities subject to a perfected first priority Encumbrance in favor of the
Agent (on behalf of the Lenders) exceeds the aggregate outstanding principal
amount of the Term Loans at any time, the Agent, without the consent of any
Lender, shall, if requested by the Borrower, release Qualifying Securities in an
amount up to such excess.

2.15 Guaranty. To secure the repayment of the Bank Indebtedness, the Borrower
     --------
will cause each of its Subsidiaries to execute and deliver to the Agent for the
benefit of the Lenders a Guaranty Agreement substantially in the form of Exhibit
                                                                         -------

          ---------------------
obligation to issue Letters of Credit and the acceleration of the Notes and the
other Bank Indebtedness following the occurrence of an Event of Default, the
Lenders shall, unless such termination and acceleration subsequently have been
rescinded, have the full panoply of rights and remedies granted to them under
this Agreement and the other Loan Documents and all those rights and remedies
granted by law to creditors, and the Agent, at the direction of the Required
Lenders, shall proceed to protect and enforce the Lenders' rights by an action
at law, suit in equity or other appropriate proceeding, whether for the specific
performance of any agreement contained herein, in the Notes or in any of the

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 such 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
                        --------

<PAGE>

it as provided in Subsection 2.6d. So long as the Letters of Credit shall remain
outstanding, any amounts declared due pursuant to this Section 7.14 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 and the Lenders 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 Agent 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

of the Letters of Credit outstanding, the Agent shall apply the amount then in
the Cash Collateral Account designated to reimburse the Agent for any drawings
under the Letters of Credit issued by it less the maximum amount available at
any time for drawing under the Letters of Credit remaining outstanding
immediately after such cancellation, expiration or reduction, if any, to the
payment in full of the outstanding Bank Indebtedness, and second, to the payment
of any excess, to the Borrower.

ARTICLE VIII. AGREEMENT AMONG LENDERS.

8.1       Appointment and Grant of Authority. Each of the Lenders hereby
          ----------------------------------
appoints PNC Bank, National Association, and PNC Bank, National Association
hereby agrees to act as, the Agent under this Agreement, the Notes and the other
Loan Documents. As such Agent, PNC Bank, National Association shall have and may
exercise such powers under this Agreement and the other Loan Documents as are
specifically delegated to the Agent, by the terms hereto or thereof, together
with such other powers as are incidental thereto. Without limiting the
foregoing, the Agent, on behalf of the Lenders, is authorized to execute all of
the Loan Documents (other than this Agreement), 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, to release any
Guarantor from its obligations under its Guaranty Agreement in the event of the
disposition of such Guarantor as permitted in this Agreement and to release any
Qualifying Securities or other Collateral from the Encumbrance granted pursuant
to the Pledge Agreement as required by and in accordance with the provisions of
this Agreement and the Pledge Agreement.

8.2       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 8.7 and 9.2 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.

8.3       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

                                      -57-
<PAGE>

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 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 Loan made by the Agent shall not
relieve any other Lender of the obligation to pay its portion of net
disbursements of Loans on any Borrowing Date, but no Lender shall be responsible
for the failure of any other Lender to make its net share of Loans to be made by
such other Lender on such Borrowing Date.

8.4       Non-Reliance on Agent. Each Lender agrees that it has, independently
          ---------------------
and without reliance on the Agent, based on such documents and information as it
has deemed appropriate, made its own credit analysis and evaluation of the
Borrower and its operations and decision to enter into this Agreement and that
it will, independently and without reliance upon the Agent, 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, the Agent shall have no duty to
keep the Lenders informed as to the performance or observance by the Borrower of
this Agreement or any other Loan Document or to inspect the properties or books
of the Borrower. The Agent, in the absence of gross negligence or willful
misconduct, shall not be liable to any Lender for its failure to relay or
furnish to the Lender any information.

8.5       Responsibility of Agent and Other Matters.
          -----------------------------------------

8.5a      Ministerial Nature of Duties. As among the Lenders and the Agent, the
          ----------------------------
Agent shall have no duties or responsibilities except those expressly set forth
in this Agreement, the Notes or in the other Loan Documents, and those duties
and responsibilities shall be subject to the limitations and qualifications set
forth in this Article VIII. The duties of the Agent shall be ministerial and
administrative in nature.

8.5b      Limitation of Liability. As among the Lenders and the Agent, neither
          -----------------------
the Agent nor any of its directors, officers, employees or agents shall be
liable 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 except for gross negligence
or willful misconduct. Without limiting the foregoing, neither the Agent nor any
of its directors, officers or employees shall be responsible for, or have any
duty to examine (i) the genuineness, execution, validity, effectiveness,
enforceability, value or sufficiency of (A) this Agreement, the Notes 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 perfection or
priority of any Encumbrance created or purported to be created under or in
connection with, any Loan Document or any other instrument or document furnished
pursuant thereto, (iii) the

                                      -58-
<PAGE>

collectibility of any amounts owed by the Borrower to the Lenders, (iv) the
truthfulness of any recitals, statements, representations or warranties made to
the Agent or the Lenders in connection with this Agreement, (v) any failure of
any party to this Agreement to receive any communication sent, including any
telegram, teletype, facsimile transmission 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 (vi) the assets, liabilities, financial
condition, results of operations or business, or creditworthiness of the
Borrower.

8.5c      Reliance. The Agent shall be entitled to act, and shall be fully
          --------
protected in acting upon, any telegram, teletype, facsimile transmission or any
writing, application, notice, report, statement, certificate, resolution,
request, order, consent, letter or other instrument, 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 employ
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 or any
other party thereto.

8.6       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,
subject to Subsection 8.5b hereof. Subject to the provisions of Subsection 8.5b,
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.

8.7       Indemnification. To the extent the Borrower does not reimburse and
          ---------------
save harmless the Agent 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 their
respective Commitment Percentages. Each Lender hereby agrees on such basis (i)
to reimburse the Agent for such Lender's pro rata share of all such reasonable
costs, expenses and disbursements on request and (ii) to the extent of each such
Lender's pro rata share, to indemnify and save harmless the Agent 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, other than
as a consequence of gross negligence or willful misconduct on the part of the
Agent, arising out of or in connection with (i) this Agreement, the Notes, the
other Loan Documents or any other agreement, instrument or document executed or
delivered in con-

                                      -59-

nection herewith or therewith, or (ii) any action taken at the request of the
Required Lenders or all of the Lenders hereunder, as the case may be, including
without limitation the reasonable costs, expenses and disbursements in
connection with defending themselves against any claim or liability, or
answering any subpoena or other process related to the exercise or performance
of any of their powers or duties under this Agreement, the other Loan Documents,
or any of the other agreements, instruments or documents executed or delivered
in connection herewith or the taking or refraining from any action under or in
connection with any of the foregoing.

8.8       Agent's Rights as a Lender. With respect to the Commitment of the
          --------------------------
Agent as a Lender hereunder, and any Loans of the Agent under this Agreement,
the other Loan Documents and any other agreements, instruments and documents
delivered pursuant hereto and any other amounts due to the Agent under this
Agreement, the Agent shall have the same rights and powers, duties and
obligations under this Agreement, the Notes, the other Loan Documents or 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. The Agent and its affiliates may accept deposits from, lend
money to, issue letters of credit for the account of, and generally engage, and
continue to engage, in any kind of business with the Borrower as if it were not
the Agent.

the Loans, interest due on the Loans, any Fees or any other amounts owing to the

amounts which are payable for the sole account of any Lender or the Agent), the
Agent shall distribute to each Lender that Lender's share of the funds so
received.

8.10      Pro Rata Sharing. Except as otherwise set forth in Section 8.3 hereof,
          ----------------

Percentages. Any sums obtained from the Borrower by any Lender by reason of the
exercise of its rights of set-off, banker's lien or in collection shall be
shared (net of costs) pro rata among the Lenders on the basis of the principal
amount of Loans outstanding. Nothing in this Section 8.10 shall be deemed to
require the sharing among the Lenders of collections specifically relating to,
or of the proceeds of any collateral securing, any other Indebtedness of the
Borrower to any Lender.

the Lenders, during such thirty (30) day period, which successor agent shall be
reasonably satisfactory to the Borrower, to serve as agent hereunder and under
the several Loan Documents. If at the end of such thirty (30) day period, the
Lenders have not appointed such a successor, the Agent shall use reasonable
commercial efforts to procure a successor reasonably satisfactory to the Lenders
and the Borrower, to serve

                                      -60-
<PAGE>

as agent for the Lenders hereunder and under the several Loan Documents. Any

the part of such former Agent or any of the parties to this Agreement except for
the execution and filing or recording of such financing statements or amendments
thereto, and such other instruments or notices, as may be necessary or
desirable, or as the Required Lenders may reasonably request, in order to
continue the perfection of the Encumbrances granted or purported to be granted
by the Pledge Agreement. After any retiring Agent's resignation hereunder as
Agent hereunder, the provisions of this Article VIII shall inure to the benefit
of such retiring Agent as to any actions taken or omitted to be taken by it
while it was Agent under this Agreement.

8.12      Notice of Default. The Agent shall not be deemed to have knowledge or
          -----------------

default".

Base Rate and the effective date thereof.

          ----------------
as the owner thereof for all purposes hereof unless and until written notice of
the assignment or transfer thereof shall have been recorded in the Register as
contemplated by Section 9.6. 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.

          ------------

event an error in computing any amount payable to any Lender 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.

8.16      Beneficiaries. Except as expressly provided herein, the provisions of
          -------------
this Article VIII are solely for the benefit of the Agent and the Lenders, 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,

9.4       Tax Withholding. Each Lender or assignee or Participant of a Lender
          ---------------
that is not incorporated under the laws of the United States of America or a
state thereof (and, upon the written request of the Agent, each other Lender or
assignee or Participant or a Lender) agrees that it will deliver to each of the
Borrower and the Agent two (2) duly completed appropriate valid Withholding
Certificates (as defined under (S)1.1441-1(c)(16) of the Income Tax Regulations
(the "Regulations")) certifying its status (i.e., United States or foreign
person) and, if appropriate, making a claim of reduced, or exemption from,
United States withholding tax on the basis of an income tax treaty or an
exemption provided by the Internal Revenue Code (the "Code"). Such delivery may
be made by electronic transmission as described in (S)1.1441-1(e)(4)(iv) of the
Regulations if the Agent establishes an electronic delivery system. The term
"Withholding Certificate" means a Form W-9; a Form W-8BEN; a Form W-8ECI; a Form
W-81MY and the related statements and certifications as required under
(S)1.1441-1(e)(3) of the Regulations; a statement described in (S)1.871-
14(c)(2)(v) of the Regulations; or any other certificates under the Code or
Regulations that certify or establish the status of a payee or beneficial owner
as a United States or foreign person. Each Lender, assignee or Participant
required to deliver to the Borrower and the Agent a valid Withholding
Certificate pursuant to the preceding sentence shall deliver such valid
Withholding Certificate as follows: (A) each Lender which is a party hereto on
the Closing Date shall deliver such valid Withholding Certificate at

                                      -65-
<PAGE>

least five (5) Business Days prior to the first date on which any interest or
Fees are payable by the Borrower hereunder for the account of such Lender; (B)
each assignee or Participant shall deliver such valid Withholding Certificate at
least five (5) Business Days before the effective date of such assignment or
Participation (unless the Agent in its sole discretion shall permit such
assignee or Participant to deliver such Withholding Certificate less than five
(5) Business Days before such date in which case it shall be due on the date
specified by the Agent). Each Lender, assignee or Participant which so delivers
a valid Withholding Certificate further undertakes to deliver to each of the
Borrower and the Agent two (2) additional copies of such Withholding Certificate
(or a successor form) on or before the date that such Withholding Certificate
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent Withholding Certificate so delivered by it, and such
amendments thereto or tensions or renewals thereof as may be reasonably
requested by the Borrower or the Agent. Notwithstanding the submission of a
Withholding Certificate claiming a reduced rate of, or exemption from, United
States withholding taxes, the Agent shall be entitled to withhold United States
federal income taxes at the full 30% withholding rate if in its reasonable
judgment it is required to do so under the due diligence requirements imposed
upon a withholding agent under (S)1.1441-7(b) of the Regulations. Further, the
Agent is indemnified under (S)1.1461-1(e) of the Regulations against any claims

of any tax it deducts and withholds in accordance with regulations under (S)1441
of the Internal Revenue Code.

          ----------------------
Borrower, the Agent and the Lenders and their respective successors and assigns,
and shall inure to the benefit of the Borrower, the Agent and the Lender and the
successors and assigns of the Agent and the Lender; provided, that the 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.

9.6       Assignments and Participations.
          ------------------------------

          -----------
9.6a, any Lender (a "Transferor Lender"), at any time, in the ordinary course of
its commercial banking business and in accordance with applicable law, may sell

portion or all of its rights and obligations under this Agreement and the Notes
then held by it, pursuant to an Assignment and Assumption Agreement
substantially in the form of Exhibit "G" executed by the Transferor Lender, such
                             -----------
Purchasing Lender, the Borrower and the Agent; subject, however to the following
requirements:

          (i)   Each such assignment must be in a minimum amount of $10,000,000,
     or, if in excess thereof, in integral multiples of $1,000,000, unless such

     Agent agrees to waive this provision;

                                      -66-
<PAGE>

          (iii) 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 Article II, or (B)
     the proposed assignee has not provided to the Borrower any tax forms
     required under Section 9.4; provided, however, no consent is required for
                                 --------  -------
     the transfer by a Lender to its Affiliate or to another Lender so long as
     the conditions in clauses (A) and (B) immediately above are satisfied;

          (iv)  The Transferor Lender shall pay to the Agent a $3,500 service
     fee for each such transfer at the time of each such transfer; and

          (v)   Each such assignment shall be of a uniform, and not a varying,
     percentage of all rights and obligations of the Transferor Lender under and
     in respect of each of the Term Commitment and the Revolving Credit
     Commitments;

provided, however the restrictions set forth in item (i) above shall not apply
--------
(x) in the case of an assignment by a Lender to an Affiliate of such Lender or
(y) in the case of any assignment by any Transferor Lender upon the occurrence
and during the continuation of an Event of Default; and provided further, that
                                                        -------- -------
upon the occurrence and during the continuance of an Event of Default the
consent of the Borrower to any assignment is not required.

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, all parties hereto agree
that (a) 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 the Commitments as
set forth therein, and (b) the Transferor Lender thereunder shall, to the extent
provided in such Assignment and Assumption Agreement, be released from its
obligations as a Lender under this Agreement. Such Assignment and Assumption
Agreement shall be deemed to amend this Agreement (without further action) 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 Commitment
Percentages 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 its 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 amounts equal to the Commitment or the Loans 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 amounts equal to the Commitment
or the Loans retained by it hereunder.

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

                                      -67-
<PAGE>

Circular issued by such Federal Reserve Bank. No such assignment shall release
the assigning Lender from its obligations and duties hereunder.

9.6b      Assignment Register. The Agent shall maintain, at its address referred
          -------------------
to in Subsection 9.3b, a copy of each Assignment and Assumption Agreement
delivered to it and a register (the "Register") for the recordation of the name,
address and Commitment of each Lender and the amount of the 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 Agent and the Lenders may
treat each Person whose name is recorded in the Register as the owner of the
Notes and the Loans and the holder of the Commitment recorded therein for all
purposes of this Agreement and the other Loan Documents. The Register shall be
available at the office of the Agent set forth in Subsection 9.3b for inspection
by either Borrower or any Lender at any reasonable time and from time to time
upon reasonable prior notice.

9.6c      Participations. Each Lender, in the ordinary course of its commercial
          --------------
banking business and in accordance with applicable law, may sell to one or more
Participants a participating interest in any Loan or Letter of Credit owing to
such Lender, the interest of such Lender in any Note, Letter of Credit or the
Commitment of such Lender. In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Lender shall remain solely responsible for the performance thereof, such Lender
shall remain the holder of its Note for all purposes under this Agreement and
the Borrower, the other Lenders and the Agent shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement or its Notes and the Participants shall have
voting rights only with respect to matters described in items (B), (C), (D), (E)
and (F) of Section 9.1.

9.6d      Provisions for Special Purpose Funding Vehicles. Notwithstanding
          -----------------------------------------------
anything to the contrary contained herein, any Lender (a "Granting Lender") may
grant to a special purpose funding vehicle (an "SPC") of such Granting Lender,
identified as such in writing from time to time by the Granting Lender to the
Agent and the Borrower, the option to provide to the Borrower all or any part of
any Loan that such Granting Lender would otherwise be obligated to make to the
Borrower provided that (i) nothing herein shall constitute a commitment to make
any Loan by such SPC and (ii) if an SPC elects not to exercise such option or
otherwise fails to provide all or any part of such Loan, the Granting Lender
shall be obligated to make such Loan pursuant to the terms hereof. The making of
a Loan by an SPC hereunder shall utilize the Commitment Percentage of the
Granting Lender to the same extent, and as if, such Loan were made by the
Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for
any payment under this Agreement for which a Lender would otherwise be liable,
for so long as, and to the extent, the related Granting Lender makes such
payment. In furtherance of the foregoing, each party hereto hereby agrees that,
prior to the date that is one year and one day after the later of (i) the
payment in full of all outstanding senior indebtedness of such SPC and (ii) the
Termination Date, it will not institute against, or join any other person in
instituting against such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings or similar proceedings under the laws of
the United States or any State thereof. In addition, notwithstanding anything to
the contrary contained in this Subsection 9.6d, such SPC may (i) with prior
written consent of the Borrower and the Agent (such consent not to be

                                      -68-
<PAGE>

unreasonably withheld) and without paying any processing fee therefor, assign
all or a portion of its interests in any Loans to its Granting Lender or to any
financial institutions providing liquidity and/or credit facilities to or for
the account of such SPC to fund the Loans made by such SPC or to support the
securities (if any) issued by such SPC to fund such Loans and (ii) disclose on a
confidential basis consistent with Section 9.19 any non-public information
relating to its Loans to any rating agency, commercial paper dealer or provider
of a surety, guarantee or credit or liquidity enhancement to such SPC. In no
event shall the Borrower be obligated to pay an SPC that has made a Loan in a
greater amount than the Borrower would have been obligated to pay under this
Agreement if the Granting Lender had made such Loan. Each Granting Lender shall
indemnify and hold harmless the Borrower and its directors, officers, employees
and agents from and against any and all losses, liabilities, claims, damages and
expenses arising from or attributable to the making of a Loan by an SPC of such
Granting Lender.

9.7       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 unenforceability without invalidating the
remaining portions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

9.8       Survival. All representations, warranties, covenants and agreements of
          --------
the Borrower contained herein, in the Notes or in the other Loan Documents or
made in writing in connection herewith or therewith 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 Bank Indebtedness. Notwithstanding the
terms of the foregoing sentence, the representations, warranties, covenants,
agreements and indemnities set forth in Sections 2.6i, 4.13, 8.7, 9.4, 9.16 and
9.18 shall survive the termination of the Commitments hereunder and the payment
in full of the Notes and the Bank Indebtedness.

9.9       Governing Law. This Agreement, each Note and each other Loan Document
          -------------
shall be a contract made under, governed by and construed in accordance with the
laws of the Commonwealth of Pennsylvania without reference to the provision
thereof regarding conflicts of law except where such law is superseded by
applicable Federal law.

9.10      Non-Business Days. Except as otherwise specifically required pursuant
          -----------------
to the terms of this Agreement, 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.

9.11      Integration. This Agreement constitutes the entire agreement between
          -----------
the parties relating to this financing transaction and it supersedes all prior
understandings and agreements, whether written or oral, between the parties
hereto concerning the subject matter of this Agreement.

credits, securities or money of the Borrower which may at any time be delivered
to, or be in the possession of, or owed by any Lender in any capacity whatever,
including the balance of any deposit account but excluding any trust or
fiduciary accounts, in each case maintained by the Borrower with such Lender.
The Borrower hereby authorizes each Lender in case of an Event of Default, at
such Lender's option, at any time and from time to time, to apply, at the
discretion of such Lender, to the payment of Bank Indebtedness, any and all such
property, credits, securities or money now or hereafter in the hands of such
Lender belonging or owed to the Borrower. Nothing herein shall restrict any
Lender's ability to set off any property, credits, securities or money of the
Borrower which may at any time be delivered to, or be in possession or owed to
any Lender in any capacity whatever to satisfy an independent obligation of the
Borrower to the Lender.

9.14      Consent to Forum. The parties hereto each hereby irrevocably consents
          ----------------
to the exclusive jurisdiction of the Court of Common Pleas of Allegheny County,
Pennsylvania, or in the District Court of the United States for the Western
District of Pennsylvania in any action or proceeding arising out of or relating
to this Agreement, the Notes or the other Loan Documents, and each party agrees
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 party at its respective address
set forth in Section 9.3, or as otherwise provided under the laws of the
Commonwealth of Pennsylvania. Further, the parties hereby specifically waive and
hereby acknowledge that the parties are estopped from raising any claim that any
such court lacks personal jurisdiction over such party so as to prohibit either
such court from adjudicating any issues raised in a complaint filed with any
such court against the Borrower or the Lenders concerning this Agreement, the
Notes or the other Loan Documents.

9.15      Waiver of Jury Trial. Each of the Agent, the Lenders and the Borrower
          --------------------

under, or in connection with, this Agreement or any other Loan Document, or any
course of conduct, course of dealing, statements (whether verbal or written) or
actions of the Agent, the Lenders or the Borrower relating hereto or thereto.
The Borrower acknowledges and agrees that it has received full and sufficient
consideration for this provision (and each other provision of each other Loan
Document to which it is a party) and that this provision is a material
inducement for the Lenders to enter into this Agreement and each such other Loan
Document.

9.16      Indemnity. The Borrower hereby agrees to indemnify the Agent, the
          ---------
Lenders and each of their respective directors, officers, employees, attorneys,
agents and Affiliates against, and hold each of them harmless from, any loss,
liabilities, damages, claims, and reasonable costs and expenses, joint or
several, (including reasonable attorneys' fees and disbursements reasonably

in addition to any other obligations or liabilities of the Borrower to the
Agents or the Lenders, or at common law or otherwise. The provisions of this
Section 9.16 shall survive the payment of the Bank Indebtedness and the
termination of this Agreement. The foregoing provisions of this Section 9.16 to
the contrary notwithstanding, the Borrower shall not be obligated to indemnify
the Agent, or any Lender pursuant to this Section 9.16 for (i) any losses,
liabilities, damages, claims or costs suffered or incurred by any of them in
connection with the administrative transfer of funds in connection with this
Agreement and which arise directly from the Agent's or such Lender's negligence
or willful misconduct, or (ii) any other losses, liabilities, damages, claims,
or costs which arise directly from the Agent's, or such Lender's gross
negligence or willful misconduct. All amounts owed pursuant to this Section 9.16

     ------------
renewal hereto or hereof may be executed in several counterparts and by each
party on a separate counterpart, each of which, when so executed and delivered,

extension or renewal, 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.
