time) on the Borrowing Date, provided that if any Lender fails to remit such

                           may not exceed the principal amount of Bid Rate Loans
                           for which offers were requested and (z) may be
                           subject to an aggregate limitation as to the
                           principal amount of Bid Rate Loans for which offers
                           being made by such quoting Lender may be accepted,

                                    (3) in the case of a Euro-Rate Auction, the
                           margin above or below the applicable Euro-Rate (the
                           "Bid Rate Margin") offered for each such Bid Rate
                           Loan, expressed as a percentage (specified to the
                           nearest 1/10,000th of 1%) to be added to or
                           subtracted from such base rate,

                                    (4) in the case of an Absolute Rate Auction,
                           the rate of interest per annum (specified to the
                           nearest 1/10,000th of 1%) (the "Bid Rate Absolute
                           Rate") offered for each such Bid Rate Loan, and

                                    (5) the identity of the quoting Lender.

A Bid Rate Quote may set forth up to three separate offers by the quoting Lender
with respect to each Interest Period specified in the related Bid Rate Quote
Request.

                           (C) Any Bid Rate Quote shall be disregarded if it:
<PAGE>   24
                                    (1) is not substantially in conformity with
                  Exhibit "E" hereto or does not specify all of the information
                  required by paragraph (iii)(B) immediately above;

                                    (2) contains qualifying, conditional or
                  similar language or, in particular, is conditioned on
                  acceptance by the Borrower of all or some specified minimum
                  principal amount of the Bid Rate Loan for which such Bid Rate
                  Quote is being made;

                                    (3) proposes terms other than or in addition
                  to those set forth in the applicable Bid Rate Quote Request;
                  or

                                    (4) arrives after the time set forth in
                  paragraph (iii)(A) above.

                  (iv) Notice to Borrower. The Administrative Agent shall notify
         the Borrower promptly, and in the case of an Absolute Rate Auction no
         later than 45 minutes after receipt by the Administrative Agent, of the
         terms (x) of any Bid Rate Quote submitted by a Lender that is in
         accordance with paragraph (iii) above and (y) of any Bid Rate Quote
         that amends, modifies or is otherwise inconsistent with a previous Bid
         Rate Quote submitted by such Lender with respect to the same Bid Rate
         Quote Request. Any such subsequent Bid Rate Quote shall be disregarded
         by the Administrative Agent unless such subsequent Bid Rate Quote is
         submitted solely to correct a manifest error in such former Bid Rate
         Quote. The Administrative Agent's notice to the Borrower shall specify
         (A) the aggregate principal amount of Bid Rate Loans for which offers
         have been received for each Interest Period specified in the related
         Bid Rate Quote Request, (B) the respective principal amounts and Bid
         Rate Margins or Bid Rate Absolute Rates, as the case may be, so offered
         and (C) if applicable, limitations on the aggregate principal amount of
         Bid Rate Loans for which offers in any single Bid Rate Quote may be
         accepted.

                  (v) Acceptance and Notice by Borrower. Not later than 11:00
         A.M. (eastern time) on (x) the third Business Day prior to the proposed
         date of Disbursement, in the case of a Euro-Rate Auction or (y) the
         proposed date of Disbursement, in the case of an Absolute Rate Auction
         (or, in either case, such other time or date as the Borrower and the
         Administrative Agent shall have mutually agreed and shall have informed
         the Lenders of not later than the date of the Bid Rate Quote Request
         for the first Euro-Rate Auction or Absolute Rate Auction for which such
         change is to be effective), the Borrower shall notify the
         Administrative Agent of its acceptance or non-acceptance of the offers
         so presented to it pursuant to Subsection (iv). In the case of
         acceptance, such notice (a "Notice of Bid Rate Borrowing") shall
         specify the aggregate principal amount of offers for each Interest
         Period that are accepted. The Borrower may accept any Bid Rate Quote in
         whole or in part; provided that:

                           (A) the aggregate principal amount of each Bid Rate
         Disbursement may not exceed the applicable amount set forth in the
         related Bid Rate Quote Request,

                           (B) the principal amount of each Bid Rate borrowing
         must be $5,000,000 or a larger multiple of $1,000,000,
<PAGE>   25
                           (C) acceptance of offers may only be made on the
         basis of ascending Bid Rate Margins or Bid Rate Absolute Rates, as the
         case may be, and

                           (D) the Borrower may not accept any offer that is
         described in subsection (iii)(C) or that otherwise fails to comply with
         the requirements of this Agreement.

                  (vi) Allocation by Administrative Agent. If offers are made by
         two or more Lenders with the same Bid Rate Margins or Bid Rate Absolute
         Rates, as the case may be, for a greater aggregate principal amount
         than the amount in respect of which such offers are accepted for the
         related Interest Period, the principal amount of Bid Rate Loans in
         respect of which such offers are accepted shall be allocated by the
         Administrative Agent among such Lenders as nearly as possible (in
         multiples of $1,000,000, as the Administrative Agent may deem
         appropriate) in proportion to the aggregate principal amounts of such
         offers. Determinations by the Administrative Agent of the amounts of
         Bid Rate Loans shall be conclusive in the absence of manifest error.

                  (vii) Bid Rate Loan Prepayment. No Bid Rate Loan shall be
prepaid prior to the end of the relevant Bid Rate Interest Period without the
prior consent of the Lender extending such Bid Rate Loan.

2.2d BID RATE LOAN INTEREST. Interest on the Bid Rate Loans shall accrue at the
rate per annum agreed upon between the Lender or Lenders making such Bid Rate
Loans and the Borrower pursuant to the Bid Rate selection procedures set forth
in Subsection 2.2c above.

2.2e BASE RATE OPTION BORROWING IN EVENT OF CANCELLED BID RATE LOAN REQUEST. In
the event of cancellation by the Borrower of a Bid Rate Loan Request pursuant to
paragraph (v) of Subsection 2.2c, the Borrower may, before 1:00 P.M. (eastern
time) on the day of such cancellation, submit to the Administrative Agent a
request for a Disbursement under the Revolving Credit to be made on the day of
such cancellation and to bear interest at the Base Rate Option. The Lenders
shall use their best efforts to make their respective pro rata shares of such
Disbursement available at the office of the Borrower prior to 2:00 P.M. (eastern
time) on the date of such Disbursement in accordance with the procedures set
forth in Subsection 2.1e.

2.3 SWING LINE LOANS.

2.3a SWING LINE OPTION. Subject to the provisions of this Section 2.3, the
Administrative Agent agrees that the Borrower may request Swing Line Loans, in
an aggregate amount at any one time outstanding not to exceed the lesser of (i)
$35,000,000 or (ii) an amount which, when added to the aggregate principal
amount of all other Loans then outstanding does not exceed the aggregate amount
of the Commitments. The Administrative Agent shall have no obligation to make
Swing Line Loans hereunder on or after the Termination Date.

2.3b LIMITATIONS ON AND EVIDENCE OF SWING LINE LOANS. Each Swing Line Loan or
repayment of a Swing Line Loan must be in the minimum principal amount of
$250,000 or, if in excess of $250,000, in integral multiples of $100,000. Swing
Line Loans shall be repaid on the date agreed upon by the Borrower and the
Administrative Agent, not more than seven (7) days after the making of the Swing
Line Loan and in no event after the Termination Date. The obligation of the
Borrower to repay, prior to the Termination Date, the aggregate unpaid
<PAGE>   26
principal amount of such Swing Line Loans advanced by the Administrative Agent
shall be evidenced by the Swing Line Note substantially in the form of Exhibit
"F" hereto. The principal amount actually due and owing the Administrative Agent
shall be the aggregate unpaid principal amount of all Disbursements of Swing
Line Loans made by the Administrative Agent, all as shown on the Swing Line Loan
Account established pursuant to Section 2.3f.

2.3c SWING LINE LOAN PROCEDURE. The Borrower may from time to time from the
Closing Date to the Business Day immediately prior to the Termination Date
request a Swing Line Loan. Such request shall be made not later than 2:00 P.M.
(Pittsburgh, Pennsylvania time) on the date of the proposed Swing Line Loan.
Such request may be made to the Administrative Agent orally or in writing and if
orally confirmed in writing. The Administrative Agent shall make the Swing Line
Loan available to the Borrower not later than 5:00 P.M. (Pittsburgh,
Pennsylvania time) on the same Business Day such Swing Line Loan is requested.

2.3d SWING LINE LOAN INTEREST. Interest on the Swing Line Loans shall accrue at
a rate of interest per annum as offered by the Administrative Agent in its sole
and absolute discretion for such Swing Line Interest Periods as offered by the
Administrative Agent in its sole and absolute discretion.

2.3e RISK PARTICIPATION. Upon the disbursement of each Swing Line 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 Swing Line Loan, in an amount equal
to (i) such Lender's Commitment Percentage (ii) multiplied by the outstanding
principal amount of such Swing Line Loan on the date of the Event of Default;
provided, however, no Lender shall participate in any Swing Line Loan made after
a notice of an Event of Default has been delivered pursuant to this Agreement.
If and to the extent the Administrative Agent receives payment of principal or
interest on a participated Swing Line Loan, the Administrative Agent shall
deliver to each Lender such Lender's Commitment Percentage of such payment.

2.3f SWING LINE LOAN ACCOUNT. The Administrative Agent shall maintain on its
books as a sub-account of the Loan Account, a Swing Line Loan Account in the
name of the Borrower with respect to any Swing Line Loans made, repayments and
prepayments of the principal thereof, and the computation and payment of
interest thereon. Upon the request of the Borrower to the Administrative Agent,
the Administrative Agent shall promptly furnish to the Borrower a statement of
the Swing Line Loan Account. The failure to record any such amount shall not
limit or otherwise affect the obligations of the Borrower hereunder or under the
Swing Line Note to repay all amounts owed hereunder and thereunder together with
all interest accrued thereon and all other fees and charges provided herein and
therein. Except in the case of manifest error, the Swing Line Loan Account shall
be conclusive evidence as to the amount at any time due to the Administrative
Agent from the Borrower under the Swing Line Note.

2.4 INTEREST RATES, INTEREST PAYMENT AND CERTAIN PROVISIONS RELATING TO INTEREST
AND FEES.

2.4a 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 2.4. The Borrower shall pay accrued interest on the unpaid
principal balance of the Loans in arrears: (i) with respect to
<PAGE>   27
each Base Rate Portion, at the Base Rate on the last Business Day of each Fiscal
Quarter during the term thereof; (ii) with respect to each Euro-Rate Portion, at
the Adjusted Euro-Rate on the last day of each Euro-Rate Interest Period as
provided for in Subsection 2.4c (provided, however, if the Euro-Rate 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 Euro-Rate Interest Period and (B) the last day of such
Euro-Rate Interest Period); (iii) with respect to each Bid Rate Loan, at the Bid
Rate on the last day of each Bid Rate Interest Period as provided for in
Subsection 2.4c (provided, however, if the Bid Rate Interest Period chosen for a
Bid Rate Loan exceeds ninety (90) days, interest on that Bid Rate Loan shall be
due and payable every ninety (90) days during such Bid Rate Interest Period and
on the last day of such Bid Rate Interest Period); (iv) with respect to each
Swing Line Loan, at the Swing Line Interest Rate on the last Business Day of
each month during which such Swing Line Loans were outstanding; and (v) with
respect to all such Loans, 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.

2.4b INTEREST RATE OPTIONS. The unpaid principal amount of the Revolving Credit
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 Revolving Credit Loans and may select different Interest Periods to apply
simultaneously to different Portions of the Euro-Rate Portions of the Revolving
Credit 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 utilization of the Commitments.

2.4c 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 Revolving Credit Loans or select, convert or
renew a Bid Rate Loan to which the Bid Rate Margin applies, 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 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 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
<PAGE>   28
                  (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.

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

                  (i) If a Euro-Rate Interest Period is elected with regard to
         amounts outstanding under the Revolving Credit and such Interest Period
         would end after the Termination Date, such Interest Period shall end on
         the Termination Date; and

                  (ii) At no time may there be more than seven (7) Euro-Rate
         Interest Periods in effect relating to Revolving Credit Loans;
         provided, however if a Base Rate Portion is outstanding there shall be
         not more than six (6) Euro-Rate Interest Periods in effect relating to
         Revolving Credit Loans.

2.4d 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. Elections of Bid Rate Loans
shall expire as to each such Bid Rate Loan at the end of the applicable Bid Rate
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 2.4c) 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 Euro-Rate 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 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 as
provided above, shall automatically be converted to the Base Rate Option.

2.4e NOTIFICATION OF ELECTION OF AN INTEREST RATE OPTION. The Borrower, by an
Authorized Officer, shall notify the Administrative Agent of (i) each election
or renewal of an Option and each conversion from one Option to another, (ii) the
Portion of the Revolving Credit
<PAGE>   29
Loans then outstanding to be allocated to each Option and (iii) where relevant,
the Interest Periods applicable to each Option, by communication as provided for
in this Agreement. Any such communication 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.

2.4f INTEREST AFTER MATURITY. After the principal amount of all or any part of
the Base Rate Portions of the Revolving Credit 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. After the occurrence of and
during the continuance of an Event of Default and whether or not judgment has
been entered against the Borrower on the Revolving Credit Notes, the Bid Rate
Notes and the Swing Line Note, all Euro-Rate Portions, Bid Rate Loans and Swing
Line Loans 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, the Bid
Rate Option and the Swing Line Interest Rate, as the case may be, 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.

2.5 YIELD-PROTECTION, CAPITAL ADEQUACY AND MISCELLANEOUS PROVISIONS RELATING TO
EURO-RATE.

2.5a YIELD PROTECTION. Notwithstanding other provisions of this Section 2.5:

                  (i) If any Governmental Rule (including, without limitation,
         Regulation D), 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 any 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 of a Lender and payable
         to any Governmental Authority in the United States of America or any
         state thereof); or

                           (B) 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 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 any
         Lender applicable to the 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 any Lender any other obligation or
         condition with respect to this Agreement,
<PAGE>   30
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, within thirty (30) days of such Lender's
                  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 2.11) 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 2.5a 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.

                  (iii) Failure or delay on the part of any Lender or the
         Administrative Agent to demand compensation pursuant to this Section
         2.5 shall not constitute a waiver of such Lender's or the
         Administrative Agent's right to demand such compensation; provided that
         the Borrower shall not be required to compensate a Lender or the
         Administrative Agent pursuant to this Section 2.5 for any increased
         costs or reduction incurred more than 180 days prior to the date that
         such Lender or the Administrative Agent, as the case may be, notifies
         the Borrower of the change in Government Rule (or interpretation
         thereof) giving rise to such increased costs or reduction and of such
         Lender's or the Administrative Agent's intention to claim compensation
         therefor; provided further that, if the change in Government Rule (or
         interpretation thereof) giving rise to such increased costs or
         reductions is retroactive, then the 180-day period referred to above
         shall be extended to include the period of retroactive effect thereof.

2.5b 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 Revolving Credit Loans, Bid Rate Loans or Swing
Line 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
<PAGE>   31
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 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.

2.5c EURO-RATE UNASCERTAINABLE. If, on any date on which the Adjusted Euro-Rate
would otherwise be set, the Administrative 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 Administrative Agent
shall give prompt notice of such determination to the Borrower and the Lenders
and, until the Administrative 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. 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.

2.5d 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
Revolving Credit Loans under the Euro-Rate Option or Bid Rate Loans to which the
Bid Rate Margin applies (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 Revolving Credit 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 or any Bid Rate Loan
         to which the Bid Rate Margin applies 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
<PAGE>   32
         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.

2.6 FEES.

2.6a CLOSING FEE. The Borrower agrees to pay to the Lenders, on or before the
Closing Date, a Closing Fee in the amounts agreed to by the Borrower and each
Lender.

2.6b FACILITY FEE. The Borrower agrees to pay to the Lenders, on a pro rata
basis, beginning on March 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 Facility Fee calculated
at a rate per annum equal to the Facility Fee Rate, on the daily (computed at
the opening of business) average amount of the Commitment for the quarter then
ending; provided, however, the first payment under this Subsection 2.6b shall be
only for the actual number of days elapsed between the actual execution of this
Agreement and March 31, 2001 and the last payment under this Subsection 2.6b
shall be only for the actual number of days elapsed between the last quarterly
payment date and the Termination Date.

2.6c AGENT'S FEE. The Borrower agrees to pay to the Administrative Agent for its
own account the non-refundable Agent's Fees for the Administrative Agent's
services hereunder under the terms of that certain letter (the "Agent's Letter")
between the Borrower and Administrative Agent dated November 30, 2000, as the
same may be amended from time to time.

2.6d ARRANGEMENT FEE. The Borrower agrees to pay to the Co-Lead Arrangers the
non-refundable Arrangement Fee for the Co-Lead Arrangers' services hereunder
under the terms of that certain letter (the "Arrangement Letter") among the
Borrower and the Co-Lead Arrangers dated November 30, 2000, as the same may be
amended from time to time.

2.7 CALCULATION OF INTEREST AND FACILITY FEE. The calculation of the amount of
interest due and owing to each Lender shall be made by each Lender and shall be
evidenced by such Lender posting the amount of interest due under such Lender's
Revolving Credit Loans and Bid Rate Loans to the Loan Account established by
such Lender pursuant to Section 2.13. The Facility 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 Facility Fee due and owing to each Lender shall be made by
each Lender and shall be evidenced by posting such amount due under the Loan
Account established by such Lender pursuant to Section 2.13.

2.8 EXTENSION OF TERMINATION DATE. The Termination Date may be extended, in the
manner set forth in this Section 2.8, on January 5, 2002 and on each anniversary
of such date (an "Extension Date") for an additional one-year period. If the
Borrower wishes to request an extension of the Termination Date on any Extension
Date, it shall give written notice to that effect to the Administrative Agent
not less than forty-five (45) nor more than sixty (60) days prior to such
Extension Date. Each Lender will use its best efforts to respond to such
request, whether affirmatively or negatively, within thirty (30) days after
receipt of such notice from the Administrative Agent. If the Borrower shall have
received affirmative responses from all the Lenders, such response to be in the
sole and absolute discretion of each Lender, then, subject to receipt by the
Borrower of counterparts of an agreement duly completed and signed by the
Borrower and each such Lender (an "Extension Agreement"), the Termination Date
shall be extended, effective on such Extension Date, for an additional one-year
period to the date stated
<PAGE>   33
in such Extension Agreement. If the Borrower shall not have received affirmative
responses from all Lenders the Termination Date shall not be extended. For
purposes of this Section 2.8, the failure of any Lender to respond shall be
deemed to be a negative response from such Lender.

2.9 SUBSTITUTION OR REPLACEMENT OF A LENDER. The Borrower shall have the right
(provided that at such time, no Event of Default and no Potential Default has
occurred and is continuing), in its sole discretion, to either:

                  (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 2.11, upon three (3) days
         prior notice if the Loans outstanding include Revolving Credit Loans
         bearing interest under the Euro-Rate Option or the Bid 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 Section 2.5a or 2.5b;

                  (ii) the obligation of such Lender to make Revolving Credit
         Loans which bear or are to bear interest under the Euro-Rate Option has
         been suspended pursuant to Subsection 2.5d; or

                  (iii) such Lender has responded negatively to a request for
         extension of the Termination Date pursuant to Section 2.8.

                  Provided, any proposed substitute lending institution, which
is not a Lender prior to the Borrower's selection thereof, must be acceptable to
the Administrative Agent, whose consent shall not be unreasonably withheld, 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 Administrative Agent)
must be complied with.

2.10 LOAN REPAYMENT. Each repayment of the Revolving Credit 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 Administrative Agent by 11:00
A.M. (eastern time) on the day of the proposed repayment, in the case of
Revolving Credit Loans bearing interest at the Base Rate or (ii) three (3)
Business Days' prior oral or written notice to the Administrative Agent, in the
case of Revolving Credit Loans bearing interest at the Adjusted Euro-Rate,
followed immediately thereafter by the Borrower's written confirmation to the
Administrative Agent of any oral notice, may repay the outstanding amount of the
Revolving Credit 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 2.11
<PAGE>   34
below. The Borrower may prepay any Portion of the Revolving Credit Loans bearing
interest at the Base Rate without premium or penalty.

                  In the event that principal payments are received on a day on
which principal payments are due on Revolving Credit Loans and Bid Rate Loans
the principal payments shall be applied: first, to repay in full the principal
amount of the Revolving Credit Loans then due and payable, if any; and second,
to repay in full the principal amount of the Bid Rate Loans then due and
payable, if any.

                  Any repayment of the Loans shall increase, by the amount of
that repayment, the unborrowed balance of the Commitment; it being contemplated
that the Borrower may repay and reborrow from time-to-time under the Commitment
until the Termination Date. All Loans outstanding on the Termination Date shall
become due and payable in full on such date.

2.11 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 Revolving
Credit Loans or any Bid Rate Loan on a day other than the last day of the
applicable Interest Period, (iii) the Borrower shall convert any Portion to the
Base Rate Option from another Option pursuant to subsection 2.4d on a day other
than the last day of the relevant Interest Period, or (iv) 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 or Notice of Bid Rate Borrowing, 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.

2.12 VOLUNTARY REDUCTION OF AVAILABILITY. At any time and from time to time upon
no less than two (2) Business Days prior written notice to the Administrative
Agent, the Borrower may terminate, in whole or in part, without penalty, the
then unused portion of the Commitments, thereby causing a corresponding
abatement of the Facility Fee. Each such reduction shall be in a minimum
principal amount of $5,000,000 or in integral multiples thereof. The Facility
Fee shall cease to accrue with respect to any unused portion of the commitments
so terminated on either (i) the date two (2) Business Days after receipt of such
notice or (ii) the date so designated in the written notice if such written
notice sets forth an effective date of such termination which is more than two
(2) Business Days after such notice is given to the Administrative Agent. Notice
of termination once given shall be irrevocable and the portion of the
Commitments so terminated shall not be available for borrowing once such notice
has been given under the terms hereof. The Administrative Agent shall promptly
notify each Lender of its pro rata share of such terminated unused portion and
the date of each such termination.

2.13 LOAN ACCOUNT. Each Lender shall open and maintain on its books a Loan
Account in the name of the Borrower with respect to Disbursements made,
repayments, prepayments, the computation and payment of interest and the
Facility Fee and the computation of other amounts due and sums paid and payable
to such Lender pursuant to this

<PAGE>   35
Article II. Such Loan Account shall be prima facie evidence as to the amount at
any time due to such Lender from the Borrower pursuant to this Article II;
provided, however, that the failure of a Lender to make notations, or to make
accurate notations, on its Loan Account including without limitation notations
with respect to interest and Facility Fees pursuant to Section 2.7 shall not
limit, expand or otherwise affect any obligations of the Borrower hereunder.

2.14 PAYMENT FROM ACCOUNTS MAINTAINED BY BORROWER. In the event that any payment
of principal, interest, Facility Fee or any other amount due to the Lenders or
the Administrative Agent under the Agreement, the Notes or the other Loan
Documents is not paid when due, the Administrative Agent is hereby authorized to
effect such payment by debiting any demand deposit account of the Borrower
maintained with the Administrative Agent (excluding however any special purpose
fiduciary accounts, which are designated as such at the time of their creation,
and 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 Administrative Agent hereunder or by operation of law.

2.15 TIME, PLACE AND MANNER OF PAYMENTS. All payments to be made by the Borrower
under the Notes (other than those provided for in Sections 2.5 and 2.11 hereof),
and of all fees and any other amounts due hereunder (excepting the Closing Fee,
the Agent's Fees and the Arrangement Fee) shall be made at the principal office
of the Administrative Agent for the ratable account of the Lenders. The
Administrative 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 2.5 or 2.11 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
available funds no later than 1:00 P.M. (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.

ARTICLE III.  REPRESENTATIONS AND WARRANTIES.

Agreement, the Notes or the other Loan Documents or will not have a Material
Adverse Effect.

3.2 CORPORATE AUTHORITY. The Borrower is duly authorized to execute and deliver

7.11 CROSS-DEFAULT. An "Event of Default" shall occur under that certain Credit
Agreement dated as of January 5, 2001 by and among New Jersey Natural Gas
Company, as the borrower, PNC Bank, National Association, as the administrative
agent, and the several lender parties thereto, as such agreement may be amended,
modified, renewed, extended or replaced from time to time, unless expressly
waived in writing or otherwise cured.

7.12 CONSEQUENCES OF AN EVENT OF DEFAULT. If one or more of the Events of
Default occur then (a) if such Event of Default is set forth in Sections 7.3 or
7.4, the Commitments shall automatically terminate and the Notes then
outstanding shall become immediately due and payable, without necessity of
demand, presentation, protest, notice of dishonor or notice of default; or (b)
if such Event of Default is set forth in any of the remaining Sections of this
Article VII, then the Administrative Agent, at the request of the Required
Lenders, and without notice to the Borrower, shall declare the Borrower in
default hereunder, and upon such declaration, shall, at the request of the
Required Lenders, terminate the Commitment and/or declare the Notes then
outstanding immediately due and payable, without necessity of any further
demand, presentation, protest, notice of dishonor or further notice of default,
whereupon such Notes shall be immediately due and payable.

7.13 REMEDIES UPON DEFAULT. Upon the termination of the Commitments and
acceleration of the Notes 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 all those rights and remedies granted by law to creditors,
and the Administrative 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 other Loan
Documents, or for an injunction against a violation of any of the terms hereof
or thereof, or in aid of the exercise of any power granted hereby or thereby or
by law. No right, power or remedy conferred by this Agreement, in the Notes, or
by any other Loan Document, upon the Administrative Agent or the Lenders shall
be exclusive of any other right, power or remedy referred to herein or therein
or now or hereafter available at law, in equity, by statute or otherwise. No
exercise of any one right or remedy shall be deemed a waiver of other rights or
remedies. The rights and remedies of the Administrative Agent and the Lenders
specified herein are for the sole and exclusive benefit, use and protection of
the Administrative Agent and the Lenders, and the Administrative Agent and the
Lenders shall be entitled, but shall have no duty or obligation, to exercise or
to refrain from exercising any right or remedy reserved to the Administrative
Agent or the Lenders hereunder.
<PAGE>   50
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 Administrative Agent under this Agreement, the Notes and the other
Loan Documents. As such Administrative 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 Administrative Agent, by the
terms hereto or thereof, together with such other powers as are incidental
thereto. Without limiting the foregoing, the Administrative Agent, on behalf of
the Lenders, 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.

8.2 DELEGATION OF DUTIES. The Administrative 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 Administrative 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 ADMINISTRATIVE AGENT ON LENDERS FOR FUNDING. Unless the
Administrative Agent shall have received notice from a Lender prior to any
Borrowing Date that such Lender will not make available to the Administrative
Agent such Lender's portion of net disbursements of Loans, the Administrative
Agent may assume that such Lender has made such portion available to the
Administrative Agent and the Administrative 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 Administrative Agent on or prior to
any Borrowing Date, such Lender and the Borrower severally agree to repay to the
Administrative 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 Administrative
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 Administrative 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 Administrative 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.

8.4 NON-RELIANCE ON ADMINISTRATIVE AGENT. Each Lender agrees that it has,
independently and without reliance on the Administrative 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 Administrative 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 Administrative 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 document or instrument referred to or provided for herein
or to inspect the properties or books of the
<PAGE>   51
Borrower. The Administrative 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 ADMINISTRATIVE AGENT AND OTHER MATTERS.

8.5a MINISTERIAL NATURE OF DUTIES. As among the Lenders and the Administrative
Agent, the Administrative 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
Administrative Agent shall be ministerial and administrative in nature.

8.5b LIMITATION OF LIABILITY. As among the Lenders and the Administrative Agent,
neither the Administrative 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 Administrative 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 Administrative 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 collectibility of any amounts owed by the Borrower
to the Lenders, (iii) the truthfulness of any recitals, statements,
representations or warranties made to the Administrative Agent 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, 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 (v) the assets, liabilities, financial condition, results of
operations or business, or creditworthiness of the Borrower.

8.5c RELIANCE. The Administrative 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 Administrative Agent in good faith to be genuine and correct and
to have been signed or sent or made by a proper Person. The Administrative 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 Administrative 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 Administrative Agent with reasonable care. The Administrative
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 ADMINISTRATIVE AGENT; INSTRUCTIONS FROM THE
LENDERS. The Administrative 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 Administrative Agent's rights, powers or
discretion herein or under any Loan Documents, provided that the Administrative
Agent shall not be required to take any action which exposes the Administrative
<PAGE>   52
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 Administrative 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 Section 8.5b hereof. Subject to the
provisions of Section 8.5b, no Lender shall have any right of action whatsoever
against the Administrative Agent as a result of the Administrative 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 Administrative Agent according to the terms hereof for and from all
reasonable 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 Administrative 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 Administrative 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 Administrative Agent, other than as a consequence of
gross negligence or willful misconduct on the part of the Administrative 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 connection 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 ADMINISTRATIVE AGENT'S RIGHTS AS A LENDER. With respect to the Commitment of
the Administrative Agent as a Lender hereunder, and any Loans of the
Administrative 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 Administrative Agent under this Agreement, the
Administrative 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 Administrative Agent. The Administrative Agent may accept deposits
from, lend money to, and generally engage, and continue to engage, in any kind
of business with the Borrower as if it were not the Administrative Agent.

8.9 PAYMENT TO LENDERS. Except as otherwise set forth in Section 8.3 hereof,
promptly after receipt from the Borrower of any principal repayment of the
Loans, interest due on the Loans and any Facility Fees owing to the Lenders or
other amounts due under any of the Loan Documents (except for such amounts which
are payable for the sole account of any Lender or the Administrative Agent), the
Administrative Agent shall distribute to each Lender that Lender's share of the
funds so received.
<PAGE>   53
8.10 PRO RATA SHARING. Except as otherwise set forth in Section 8.3 hereof, all
interest and principal payments on the Revolving Credit Loans and all Facility
Fees are to be divided pro rata among the Lenders in proportion to the Revolving
Credit Loans outstanding from each Lender or, if no such Revolving Credit Loans
are then outstanding, in accordance with their respective Commitment
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

or of the proceeds of any collateral securing, any other Indebtedness of the
Borrower to any Lender.

8.11 SUCCESSOR ADMINISTRATIVE AGENT.

8.11a RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative Agent may resign
as Administrative Agent hereunder by giving thirty (30) days' prior written
notice to the Lenders and the Borrower. If such notice shall be given, the
Lenders shall appoint a successor agent for 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 Administrative Agent shall use reasonable commercial efforts to
procure a successor reasonably satisfactory to the Lenders and the Borrower, to
serve as agent for the Lenders hereunder and under the several Loan Documents.
Any such successor agent shall succeed to the rights, powers and duties of the
Administrative Agent.

8.11b RIGHTS OF THE FORMER ADMINISTRATIVE AGENT. Upon the appointment of such
successor agent or upon the expiration of such thirty (30) day period (or any
longer period to which the Administrative Agent has agreed), the former
Administrative Agent's rights, powers and duties as Administrative Agent shall
be terminated, without any other or further act or deed on the part of such
former Administrative Agent or any of the parties to this Agreement. After any
retiring Administrative Agent's resignation hereunder as Administrative Agent
hereunder, the provisions of this Article VIII shall inure to the benefit of
such retiring Administrative Agent as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement.

8.12 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of an Event of Default unless the
Administrative 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".

8.13 NOTICES. The Administrative Agent shall promptly send to each Lender a copy
of all notices received from the Borrower pursuant to the provisions of this
Agreement or the other Loan Documents promptly upon receipt thereof. The
Administrative Agent shall promptly notify the Borrower and the other Lenders of
each change in the Base Rate and the effective date thereof.

8.14 HOLDERS OF NOTES. The Administrative Agent may deem and treat any payee of
any Note as the owner thereof for all purposes hereof unless and until written
notice of the assignment or transfer thereof shall have been filed with the
Administrative Agent. Any request, authority or consent of any person who at the
time of making such request or giving such
<PAGE>   54
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.

8.15 CALCULATIONS. In the absence of gross negligence or willful misconduct, the
Administrative Agent shall not be liable for any error in computing the amount
payable to any Lender whether in respect of the Loans, Fees or any other amounts
due to the Lenders under this Agreement. In the event an error in computing any
amount payable to any Lender is made, the Administrative Agent, the Borrower and
each affected 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 IX are solely for the benefit of the Administrative 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, the Administrative 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.

ARTICLE IX.  GENERAL PROVISIONS

9.1 AMENDMENTS AND WAIVERS. Subject to the remaining provisions of this Section
9.1, the Administrative Agent, the Lenders and the Borrower may, from time to

consent of the Required Lenders), and then such waiver or consent shall be
effective only for the specific instance and for the specific purpose for which
it is given; provided, however, that no amendment, renewal, modification, waiver

Any such supplemental agreement shall apply equally to the Borrower and each of
the Lenders and shall be binding upon the Borrower, the Lenders, the
Administrative Agent and all future holders of the Notes. In the case of any
waiver, the Borrower, the Lenders and the Administrative Agent shall be restored
to their 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.

9.2               EXPENSES.  The Borrower shall pay:

                  (i) All reasonable costs and expenses of the Administrative

9.3c NOTICE TO THE LENDERS. All notices required to be delivered to the Lenders
pursuant to this Agreement shall be sent to the addresses set forth on the
signature pages of the Agreement or such Lender's signature page to the
Assignment and Assumption Agreement executed by it as a Purchasing Lender.

9.4 TAX WITHHOLDING. At least five (5) Business Days prior to the first date on
which interest or fees are payable hereunder for the account of each Lender,
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 agrees that it
will deliver to the Administrative Agent and the Borrower two (2) duly completed
copies of either (i) IRS Form W-9, 1001 or 4224 or such other applicable form
prescribed by the IRS, certifying in each case that such Lender or assignee or
participant of a Lender is entitled to receive payments under this Agreement or
its Notes without deduction or withholding of United States federal income
taxes, or is subject to such tax at a reduced rate under an applicable tax
treaty or (ii) IRS Form W-8 or such other applicable form prescribed by the IRS
or a certificate of such Lender or assignee or participant of a Lender
indicating that no such exemption or reduced rate of taxation is allowable with
respect to such payments. Each Lender or assignee or participant of a Lender
which delivers an IRS Form W-8, W-9, 4224 or 1001 further undertakes to deliver
to the Administrative Agent and the Borrower two (2) additional copies of any
such form (or any successor form) on or before the date on which that form
expires or becomes obsolete 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 requested by the Borrower
or the Administrative Agent, either certifying that such Lender or assignee or
participant of a Lender is entitled to receive payments under this Agreement or
its 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 the date on which that no such exemption or reduced rate is
allowable. The Administrative Agent shall be entitled to withhold, from each
payment
<PAGE>   58
hereunder or under the Notes payable to it, United States federal income taxes
at the full withholding rate unless each Lender referred to in the first
sentence of this Section 9.4 establishes an exemption or at the applicable
reduced rate established pursuant to the above provisions.

9.5 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the Borrower,
the Administrative Agent and the Lenders and their respective successors and
assigns, and shall inure to the benefit of the Borrower, the Administrative
Agent and the Lender and the successors and assigns of the Administrative 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 ASSIGNMENTS. Subject to the remaining provisions of this Subsection 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 to
one or more financial institutions (individually a "Purchasing Lender"), a
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 "I" executed by the Transferor Lender, such
Purchasing Lender, the Borrower (if Borrower's consent is required for such
transfer as provided below) and the Administrative Agent; subject, however to
the following requirements:

                  (i) Each such assignment must be in a minimum amount of
         $5,000,000, or, if in excess thereof, in integral multiples of
         $1,000,000, unless such Lender's Commitment is less than $5,000,000, in
         which case such assignment shall be in the full amount of such Lender's
         Commitment;

                  (ii) During the first ninety (90) days following the Closing
         Date, each assignment made shall become effective only on a date which
         coincides with the expiration date of any Euro-Rate Interest Period
         then in effect, unless the Administrative Agent agrees to waive this
         provision;

                  (iii) The Administrative 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 received 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; and

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

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.
<PAGE>   59
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 a Commitment 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 Administrative 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 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 an amount 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 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 Administrative 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 names and addresses of the Lenders 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 Administrative Agent and
the Lenders may treat each Person whose name is recorded in the Register as the
owner of the Loans recorded therein for all purposes of this Agreement. The
Register shall be available at the office of the Administrative 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 owing to such Lender, the
interest of such Lender in any Notes 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 Notes
for all purposes under this Agreement and the Borrower, the other Lenders and
the Administrative 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.
<PAGE>   60
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
Administrative 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 Section 9.6d, such SPC may (i) with
prior written consent of the Borrower and the Administrative Agent (such consent
not to be 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 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 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.

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 State of New Jersey without reference to the provision thereof regarding
conflicts of law except where such law is superseded by applicable Federal law.
<PAGE>   61
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.

9.12 HEADINGS. Article, Section and other headings used in this Agreement are
intended for convenience only and shall not affect the meaning or construction
of this Agreement.

9.13 SET-OFF. The Borrower hereby gives to the Lenders a lien and security
interest for the amount of any Bank Indebtedness upon and in any property,
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 nonexclusive 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.

9.15 WAIVER OF JURY TRIAL. Each of the Administrative Agent, the Lenders and the
Borrower hereby knowingly, voluntarily and intentionally waive any rights they
may have to a trial by jury in respect of any litigation based hereon, or
arising out of, 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 Administrative 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.
<PAGE>   62
9.16 INDEMNITY. The Borrower hereby agrees to indemnify the Administrative
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
incurred by any such Person in connection with the preparation for or defense of
any pending or threatened claim, action or proceeding) suffered or incurred by
any of them under any applicable federal or state law or otherwise caused by,
arising out of, resulting from or in any manner connected with, the execution,
delivery and performance of each of the Loan Documents, the Loans and any and
all transactions related to or consummated in connection with the Loans. The
indemnity set forth in this Section 9.16 shall be in addition to any other
obligations or liabilities of the Borrower to the Administrative 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
Administrative 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 Administrative 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
Administrative Agent's, or such Lender's gross negligence or willful misconduct.
All amounts owed pursuant to this Section 9.16 shall be part of the Bank
Indebtedness.

9.17 COUNTERPARTS. This Agreement and any amendment, modification, extension or
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,
shall be an original, but all of which together shall constitute but one and the
same instrument. In proving this Agreement or any amendment, modification,
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.

9.18 CONFIDENTIALITY. Each Lender agrees to maintain in confidence and not to
disclose without the Borrower's consent (other than to its employees,
affiliates, auditors, counsel or other professional advisors, or to another
Lender, each of which shall also be bound by this Section 9.18) any information
concerning the Borrower or its Subsidiaries furnished pursuant to this Agreement
and identified as confidential by the party so furnishing such information;
provided that any Lender may disclose any such information (a) that has become
generally available to the public, (b) if required or appropriate in any report,
statement or testimony submitted to any regulatory body having or claiming to
have jurisdiction over such Lender, (c) if required or appropriate in respect to
any summons or subpoena or in connection with any litigation, (d) in order to
comply with any law, order, regulation or ruling applicable to such Lender, or
(e) to any prospective or actual participant under Section 9.6 hereof in
connection with any contemplated or actual transfer of a participating or other
interest in such Lender's rights or liabilities hereunder; provided, that (i)
such actual or prospective transferee executes an agreement with such Lender
containing provisions substantially identical to those contained in this Section
9.18 and (ii) in the case of any disclosure under subsection (c) above, such
Lender shall (to the extent permitted by applicable law) notify the Borrower of
such disclosure so that the Borrower may seek an appropriate protective order or
waive such Lender's compliance with the provisions of this Section, it being
understood that if the Borrower has no right to obtain such a protective order
or if the Borrower does not commence procedures to obtain such a protective
order within ten (10) Business Days of the receipt of such notice,
<PAGE>   63
such Lender's compliance with this Section shall be deemed to have been waived
with respect to such disclosure.

       2.1c LONG TERM REVOLVING CREDIT LOANS. Subject to the terms and
conditions hereof and relying upon the representations and warranties herein set
forth, each Lender severally agrees to make Long Term Revolving Credit Loans to
the Borrower at any time from time to time on or after the date hereof to, but
not including, the Long Term Revolving Credit Termination Date, provided that
the aggregate principal amount of each Lender's Long Term Revolving Credit Loans
outstanding hereunder to the Borrower shall not exceed at any one time an amount
equal to such Lender's Long Term Revolving Credit Commitment Percentage of the
sum of (i) the aggregate amount of Long Term Revolving Credit Commitments then
in effect (the "Long Term Revolving Credit"), minus (ii) the principal amount of
Bid Rate Loans then outstanding. Within such limits of time and amount and
subject to the other provisions of this Agreement, the Borrower may borrow,

Term Revolving Credit Loans to the Borrower from time to time not to exceed an
aggregate principal amount at any one time outstanding equal to the amount of
its respective Long Term Revolving Credit Commitment Percentage of the Long Term
Revolving Credit. 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 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
Long Term Revolving Credit Loans hereunder on or after the Long Term Revolving
Credit Termination Date.

       2.1e REVOLVING CREDIT NOTES. The obligation of the Borrower to repay, on
or before the Short Term Revolving Credit Termination Date, the aggregate unpaid
principal amount of all Short Term Revolving Credit Loans shall be evidenced by
the several Short Term Revolving Credit Notes, each substantially in the form of
Exhibit "A-1" hereto, drawn by the Borrower to the order of a Lender in the
maximum amount of such Lender's Short Term Revolving Credit Commitment. The
principal amount actually due and owing to a Lender at any time under its Short
Term Revolving Credit Note shall be the then aggregate unpaid principal amount
of all Short Term Revolving Credit Loans made by such Lender as shown on the
Loan Account established and maintained by such Lender in accordance with
Section 2.13. The obligation of the Borrower to repay, on or before the Long
Term Revolving Credit Termination Date, the aggregate unpaid principal amount of
all Long Term Revolving Credit Loans shall be evidenced by the several Long Term
Revolving Credit Notes, each substantially in the form of Exhibit "A-2" hereto,
drawn by the Borrower to the order of a Lender in the maximum amount of such

Credit Loans made by such Lender as shown on the Loan Account established and
maintained by such Lender in accordance with Section 2.13. Each Revolving Credit
Note shall be dated the date hereof and shall be delivered to the Administrative
Agent on behalf of the Lenders on such date.

       2.1f REVOLVING CREDIT LOAN REQUEST. Except as otherwise provided herein,
the Borrower may from time to time prior to the Termination Date request the

Administrative Agent, not later than 11:00 A.M. (eastern 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

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 "B" hereto or a request by telephone immediately confirmed in writing by
letter or facsimile in such form (each, a "Revolving Credit Loan Request"), it
being understood that the Administrative Agent may rely on the authority of any
person making such a telephonic request without the necessity of receipt of such
written confirmation. Each Revolving Credit Loan Request shall be irrevocable
and shall specify (i) whether the proposed Disbursement is under the Short Term
Revolving Credit or the Long Term Revolving Credit; (ii) the proposed Borrowing
Date; (iii) 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

promptly after receipt by it of a Revolving Credit Loan Request pursuant to
Section 2.1f (but not later than noon (eastern time) on the Borrowing Date for
same day funding and 2:00 P.M. (eastern time) on the third Business Day
preceding any Borrowing Date for which any Portion of the Revolving Credit Loans

Revolving Credit or the Long Term Revolving Credit; (ii) the proposed Borrowing
Date and the time and method of disbursement of such Revolving Credit Loan;
(iii) the amount and type of such Revolving Credit Loan and the applicable
Euro-Rate Portions and Euro-Rate Interest Periods (if any); and (iv) the
apportionment among the Lenders of the Revolving Credit Loans as determined by
the Administrative Agent in accordance with Section 2.1b or 2.1d hereof, as
applicable. Each Lender shall remit the principal amount of each Revolving
Credit Loan to the Administrative Agent such that the Administrative Agent is
able to, and the Administrative Agent shall, to the extent the 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 of
the Administrative Agent in Pittsburgh, Pennsylvania prior to 2:00 P.M. (eastern
time) on the Borrowing Date, provided that if any Lender fails to remit such
funds to the Administrative Agent in a timely manner, or any Lender fails to
advise the Administrative Agent of its intention not to fund, then the
Administrative Agent may elect in its sole discretion to fund with its own funds
the Revolving Credit Loan of such Lender on the Borrowing Date, subject to the
provisions of Section 8.3 below.

       2.1h TEMPORARY REDUCTION OF AVAILABLE SHORT TERM REVOLVING CREDIT
COMMITMENT. While each Swing Line Loan advanced pursuant to Section 2.3 is
outstanding, the principal amount available to be borrowed under the aggregate
Short Term Revolving Credit Commitment shall be reduced by an amount equal to
the principal amount of each such Swing Line Loan then outstanding, and the
Short Term Revolving Credit Commitments shall be deemed to be utilized in the
amount of such Swing Line Loans for the purposes of determining the then
Applicable Euro-Rate Martin with respect to Short Term Revolving Credit Loans.
The foregoing notwithstanding, each Lender shall remain responsible for funding
its Short Term Revolving Credit Commitment Percentage of the Short Term
Revolving Credit Loans. Such reduction shall not affect the calculation of the
Short Term Facility Fee.

       2.1i TEMPORARY REDUCTION OF AVAILABLE LONG TERM REVOLVING CREDIT
COMMITMENT. While each Bid Rate Loan advanced pursuant to Section 2.2 is
outstanding, the principal amount available to be borrowed under the aggregate
Long Term Revolving Credit Commitment shall be reduced by an amount equal to the
principal amount of each such Bid Rate Loan then outstanding, and the Long Term
Revolving Credit Commitments shall be deemed to be utilized in the amount of
such Bid Rate Loans for the purposes of determining the then Applicable
Euro-Rate Margin with respect to Long Term Revolving Credit Loans. The foregoing
notwithstanding, each Lender shall remain responsible for funding its Long Term
Revolving Credit Commitment Percentage of the Long Term Revolving Credit Loans.
Such reduction shall not affect the calculation of the Long Term Facility Fee.

                     Rate Loans for which offers were requested and (z) may be
                     subject to an aggregate limitation as to the principal
                     amount of Bid Rate Loans for which offers being made by
                     such quoting Lender may be accepted,

                     1/10,000th of 1%) to be added to or subtracted from such
                     base rate,

                                        (4) in the case of an Absolute Rate

Request.

                     (C) Any Bid Rate Quote shall be disregarded if it:

                         (1) is not substantially in conformity with Exhibit "E"
                     hereto or does not specify all of the information required
                     by paragraph (iii)(B) immediately above;

                         (2) contains qualifying, conditional or similar
                     language or, in particular, is conditioned on acceptance by
                     the Borrower of all or some specified minimum principal
                     amount of the Bid Rate Loan for which such Bid Rate Quote
                     is being made;

                         (3) proposes terms other than or in addition to those

                     (iii)(A) above.

              (iv) Notice to Borrower. The Administrative Agent shall notify the

       than 45 minutes after receipt by the Administrative Agent, of the terms
       (x) of any Bid Rate Quote submitted by a Lender that is in accordance
       with paragraph (iii) above and (y) of any Bid Rate Quote that amends,
       modifies or is otherwise inconsistent with a previous Bid Rate Quote
       submitted by such Lender with respect to the same Bid Rate Quote Request.
       Any such subsequent Bid Rate Quote shall be disregarded by the
       Administrative Agent unless such subsequent Bid Rate Quote is submitted
       solely to correct a manifest error in such former Bid Rate Quote. The
       Administrative Agent's notice to the Borrower shall specify (A) the
       aggregate principal amount of Bid Rate Loans for which offers have been
       received for each Interest Period specified in the related Bid Rate Quote
       Request, (B) the respective principal amounts and Bid Rate Margins or Bid
       Rate Absolute Rates, as the case may be, so offered and (C) if
       applicable, limitations on the aggregate principal amount of Bid Rate
       Loans for which offers in any single Bid Rate Quote may be accepted.

              (v) Acceptance and Notice by Borrower. Not later than 11:00 A.M.
       (eastern time) on (x) the third Business Day prior to the proposed date
       of Disbursement, in the case of a Euro-Rate Auction or (y) the proposed
       date of Disbursement, in the case of an Absolute Rate Auction (or, in
       either case, such other time or date as the Borrower and the
       Administrative Agent shall have mutually agreed and shall have informed
       the Lenders of not later than the date of the Bid Rate Quote Request for
       the first Euro-Rate Auction or Absolute Rate Auction for which such
       change is to be effective), the Borrower shall notify the Administrative
       Agent of its acceptance or non-acceptance of the offers so presented to
       it pursuant to Subsection (iv). In the case of acceptance, such notice (a
       "Notice of Bid Rate Borrowing") shall specify the aggregate principal
       amount of offers for each Interest Period that are accepted. The Borrower
       may accept any Bid Rate Quote in whole or in part; provided that:

                                       20
<PAGE>   27

                     (A) the aggregate principal amount of each Bid Rate
       Disbursement may not exceed the applicable amount set forth in the
       related Bid Rate Quote Request,

                     (B) the principal amount of each Bid Rate borrowing must be
       $5,000,000 or a larger multiple of $1,000,000,

                     (C) acceptance of offers may only be made on the basis of
       ascending Bid Rate Margins or Bid Rate Absolute Rates, as the case may
       be, and

                     (D) the Borrower may not accept any offer that is described
       in subsection (iii)(C) or that otherwise fails to comply with the
       requirements of this Agreement.

              (vi) Allocation by Administrative Agent. If offers are made by two
       or more Lenders with the same Bid Rate Margins or Bid Rate Absolute
       Rates, as the case may be, for a greater aggregate principal amount than
       the amount in respect of which such offers are accepted for the related
       Interest Period, the principal amount of Bid Rate Loans in respect of
       which such offers are accepted shall be allocated by the Administrative
       Agent among such Lenders as nearly as possible (in multiples of
       $1,000,000, as the Administrative Agent may deem appropriate) in
       proportion to the aggregate principal amounts of such offers.
       Determinations by the Administrative Agent of the amounts of Bid Rate
       Loans shall be conclusive in the absence of manifest error.

              (vii) Bid Rate Loan Prepayment. No Bid Rate Loan shall be prepaid
       prior to the end of the relevant Bid Rate Interest Period without the
       prior consent of the Lender extending such Bid Rate Loan.

       2.2d BID RATE LOAN INTEREST. Interest on the Bid Rate Loans shall accrue
at the rate per annum agreed upon between the Lender or Lenders making such Bid
Rate Loans and the Borrower pursuant to the Bid Rate selection procedures set
forth in Subsection 2.2c above.

       2.2e BASE RATE OPTION BORROWING IN EVENT OF CANCELLED BID RATE LOAN
REQUEST. In the event of cancellation by the Borrower of a Bid Rate Loan Request
pursuant to paragraph (v) of Subsection 2.2c, the Borrower may, before 1:00 P.M.
(eastern time) on the day of such cancellation, submit to the Administrative
Agent a request for a Disbursement under the Revolving Credit to be made on the
day of such cancellation and to bear interest at the Base Rate Option. The
Lenders shall use their best efforts to make their respective pro rata shares of
such Disbursement available at the office of the Borrower prior to 2:00 P.M.
(eastern time) on the date of such Disbursement in accordance with the
procedures set forth in Subsection 2.1g.

Swing Line Loans shall be repaid on the date agreed upon by the Borrower and the
Administrative Agent, not more than seven (7) days after the making of the Swing
Line Loan and in no event after the Short Term Revolving Credit Termination
Date. The obligation of the Borrower to repay, prior to the Short Term Revolving
Credit Termination Date, the aggregate unpaid principal amount of such Swing
Line Loans advanced by the Administrative Agent shall be evidenced by the Swing
Line Note substantially in the form of Exhibit "F" hereto. The principal amount
actually due and owing the Administrative Agent shall be the aggregate unpaid
principal amount of all Disbursements of Swing Line Loans made by the
Administrative Agent, all as shown on the Swing Line Loan Account established
pursuant to Section 2.3f.

       2.3c SWING LINE LOAN PROCEDURE. The Borrower may from time to time from
the Closing Date to the Business Day immediately prior to the Short Term
Revolving Credit Termination Date request a Swing Line Loan. Such request shall

not later than 5:00 P.M. (Pittsburgh, Pennsylvania time) on the same Business
Day such Swing Line Loan is requested.

       2.3d SWING LINE LOAN INTEREST. Interest on the Swing Line Loans shall
accrue at a rate of interest per annum as offered by the Administrative Agent in
its sole and absolute discretion for such Swing Line Interest Periods as offered
by the Administrative Agent in its sole and absolute discretion.

       2.3e RISK PARTICIPATION. Upon the disbursement of each Swing Line 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 Swing Line Loan, in an
amount equal to (i) such Lender's Short Term Revolving Credit Commitment
Percentage (ii) multiplied by the outstanding principal amount of such Swing
Line Loan on the date of the Event of Default; provided, however, no Lender
shall participate in any Swing Line Loan made after a notice of an Event of
Default has been delivered pursuant to this Agreement. If and to the extent the
Administrative Agent receives payment of principal or interest on a participated
Swing Line Loan, the Administrative Agent shall deliver to each Lender such
Lender's Short Term Revolving Credit Commitment Percentage of such payment.

       2.3f SWING LINE LOAN ACCOUNT. The Administrative Agent shall maintain on
its books as a sub-account of the Loan Account, a Swing Line Loan Account in the
name of the Borrower with respect to any Swing Line Loans made, repayments and
prepayments of the principal thereof, and the computation and payment of
interest thereon. Upon the request of the Borrower to the Administrative Agent,
the Administrative Agent shall promptly furnish to the Borrower a statement of
the Swing Line Loan Account. The failure to record any such amount shall not
limit or otherwise affect the obligations of the Borrower hereunder or under the
Swing Line Note to repay all amounts owed hereunder and thereunder together with
all interest accrued thereon and all other fees and charges provided herein and
therein. Except in the case of manifest error, the Swing Line Loan Account shall
be conclusive evidence as to the amount at any time due to the Administrative
Agent from the Borrower under the Swing Line Note.

       2.4  INTEREST RATES, INTEREST PAYMENT AND CERTAIN PROVISIONS RELATING TO
INTEREST AND FEES.

       2.4a 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 2.4. 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 Business Day of each Fiscal Quarter during
the term thereof; (ii) with respect to each Euro-Rate Portion, at the Adjusted
Euro-Rate on the last day of each Euro-Rate Interest Period as provided for in
Subsection 2.4c (provided, however, if the Euro-Rate 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 Euro-Rate Interest Period and (B) the last day of such Euro-Rate Interest
Period); (iii) with respect to each Bid Rate Loan, at the Bid Rate on the last
day of each Bid Rate Interest Period as provided for in Subsection 2.4c
(provided, however, if the Bid Rate Interest Period chosen for a Bid Rate Loan
exceeds ninety (90) days, interest on that Bid Rate Loan shall be due and
payable every ninety (90) days during such Bid Rate Interest Period and on the
last day of such Bid Rate Interest Period); (iv) with respect to each Swing Line
Loan, at the Swing Line Interest Rate on the last Business Day of each month
during which such Swing Line Loans were outstanding; and (v) with respect to all
such Loans, 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.

       2.4b INTEREST RATE OPTIONS. The unpaid principal amount of the Revolving
Credit 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 Revolving Credit Loans and may select different Interest Periods to apply
simultaneously to different Portions of the Euro-Rate Portions of the Revolving
Credit 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.

                                       23
<PAGE>   30
            (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 utilization of the Commitments.

       2.4c 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 Revolving Credit Loans or select,
convert or renew a Bid Rate Loan to which the Bid Rate Margin applies, 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 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 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.

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

            (i) If a Euro-Rate Interest Period is elected with regard to amounts
         outstanding under the Revolving Credit and such Interest Period would
         end after the Termination Date, such Interest Period shall end on the
         Termination Date; and

            (ii) At no time may there be more than seven (7) Euro-Rate Interest
         Periods in effect relating to Revolving Credit Loans; provided, however
         if a Base Rate Portion is outstanding there shall be not more than six
         (6) Euro-Rate Interest Periods in effect relating to Revolving Credit
         Loans.

       2.4d 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. Elections
of Bid Rate Loans shall expire as to each such Bid Rate Loan at the end of the
applicable Bid Rate 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 2.4c) 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

                                       24
<PAGE>   31
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 Euro-Rate 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 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 as
provided above, shall automatically be converted to the Base Rate Option.

       2.4e NOTIFICATION OF ELECTION OF AN INTEREST RATE OPTION. The Borrower,
by an Authorized Officer, shall notify the Administrative Agent of (i) each
election or renewal of an Option and each conversion from one Option to another,
(ii) the Portion of the Revolving Credit Loans then outstanding to be allocated
to each Option and (iii) where relevant, the Interest Periods applicable to each
Option, by communication as provided for in this Agreement. Any such
communication 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.

       2.4f INTEREST AFTER MATURITY. After the principal amount of all or any
part of the Base Rate Portions of the Revolving Credit 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. After the occurrence
of and during the continuance of an Event of Default and whether or not judgment
has been entered against the Borrower on the Revolving Credit Notes, the Bid
Rate Notes and the Swing Line Note, all Euro-Rate Portions, Bid Rate Loans and
Swing Line Loans 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, the Bid Rate Option and the Swing Line Interest Rate, as the case may
be, 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.

         2.5 YIELD-PROTECTION, CAPITAL ADEQUACY AND MISCELLANEOUS PROVISIONS
RELATING TO EURO-RATE.

       2.5a YIELD PROTECTION. Notwithstanding other provisions of this Section
2.5:

            (i) If any Governmental Rule (including, without limitation,
         Regulation D), 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:

                                       25
<PAGE>   32

              (A) subject any 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 of a Lender and payable to any
       Governmental Authority in the United States of America or any state
       thereof); or

              (B) 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 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 any Lender applicable to
       the 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 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 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, within
         thirty (30) days of such Lender's 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 2.11) 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 2.5a 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.

         (iii) Failure or delay on the part of any Lender or the Administrative
Agent to demand compensation pursuant to this Section 2.5 shall not constitute a
waiver of such Lender's or the Administrative Agent's right to demand such
compensation; provided

                                       26
<PAGE>   33
that the Borrower shall not be required to compensate a Lender or the
Administrative Agent pursuant to this Section 2.5 for any increased costs or
reduction incurred more than 180 days prior to the date that such Lender or the
Administrative Agent, as the case may be, notifies the Borrower of the change in
Government Rule (or interpretation thereof) giving rise to such increased costs
or reduction and of such Lender's or the Administrative Agent's intention to
claim compensation therefor; provided further that, if the change in Government
Rule (or interpretation thereof) giving rise to such increased costs or
reductions is retroactive, then the 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

       2.5b 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 Commitments (including, without limitation,
obligations in respect of any Revolving Credit Loans, Bid Rate Loans or Swing
Line 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 Commitments 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 Commitments (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 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 Commitments hereunder.

       2.5c EURO-RATE UNASCERTAINABLE. If, on any date on which the Adjusted
Euro-Rate would otherwise be set, the Administrative 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 Administrative Agent
shall give prompt notice of such determination to the Borrower and the Lenders
and, until the Administrative 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. 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.

       2.5d 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

                                       27
<PAGE>   34
thereof by any Governmental Authority, has made it unlawful for such Lender to
make or maintain the Revolving Credit Loans under the Euro-Rate Option or Bid
Rate Loans to which the Bid Rate Margin applies (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 Revolving Credit 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 or any Bid
         Rate Loan to which the Bid Rate Margin applies 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.

         2.6 FEES.

         2.6a CLOSING FEE. The Borrower agrees to pay to the Lenders on or
before the Closing Date, a Closing Fee in the amounts agreed to by the Borrower
and each Lender.

       2.6b SHORT TERM FACILITY FEE. The Borrower agrees to pay to the Lenders,
on a pro rata basis, beginning on March 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 Short Term Revolving Credit
Termination Date, a Short Term Facility Fee calculated at a rate per annum equal
to the Applicable Facility Fee Rate, on the daily (computed at the opening of
business) average amount of the Short Term Revolving Credit Commitment for the
quarter then ending; provided, however, the first payment under this Subsection
2.6b shall be only for the actual number of days elapsed between the actual
execution of this Agreement and March 31, 2001 and the last payment under this
Subsection 2.6b shall be only for the actual number of days elapsed between the
last quarterly payment date and the Short Term Revolving Credit Termination
Date.

       2.6c LONG TERM FACILITY FEE. The Borrower agrees to pay to the Lenders,
on a pro rata basis, beginning on March 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 Long Term Revolving Credit
Termination Date, a Long Term Facility Fee calculated at a rate per annum equal
to the Applicable Facility Fee Rate, on the daily (computed at the opening of
business) average amount of the Long Term Revolving Credit Commitment for the
quarter then ending; provided, however, the first payment under this Subsection
2.6c shall be only for the actual number of days elapsed between the actual
execution of this Agreement and March 31, 2001 and the last payment under this
Subsection 2.6c shall be only for the actual number of days elapsed between the
last quarterly payment date and the Long Term Revolving Credit Termination Date.

                                       28
<PAGE>   35

       2.6d AGENT'S FEE. The Borrower agrees to pay to the Administrative Agent
for its own account the non-refundable Agent's Fees for the Administrative
Agent's services hereunder under the terms of that certain letter (the "Agent's
Letter") between the Borrower and Administrative Agent dated November 30, 2000,
as the same may be amended from time to time.

       2.6e ARRANGEMENT FEE. The Borrower agrees to pay to the Co-Lead Arrangers
the non-refundable Arrangement Fee for the Co-Lead Arrangers' services hereunder
under the terms of that certain letter (the "Arrangement Letter") among the
Borrower and the Co-Lead Arrangers dated November 30, 2000, as the same may be
amended from time to time.

       2.7 CALCULATION OF INTEREST AND FACILITY FEE. The calculation of the
amount of interest due and owing to each Lender shall be made by each Lender and
shall be evidenced by such Lender posting the amount of interest due under such
Lender's Revolving Credit Loans and Bid Rate Loans to the Loan Account
established by such Lender pursuant to Section 2.13. The Facility Fees shall be
calculated on the basis of a 360 day year and actual number of days elapsed. The
calculation of the amount of the Facility Fees due and owing to each Lender
shall be made by each Lender and shall be evidenced by posting such amount due
under the Loan Account established by such Lender pursuant to Section 2.13.

       2.8                 EXTENSION OF TERMINATION DATES.

       2.8a EXTENSION OF SHORT TERM REVOLVING CREDIT TERMINATION DATE. The Short
Term Revolving Credit Termination Date may be extended, in the manner set forth
in this Subsection 2.8a, on January 4, 2002 and on each anniversary of such date
(a "Short Term Revolving Credit Extension Date") for an additional 364-day
period. If the Borrower wishes to request an extension of the Short Term
Revolving Credit Termination Date on any Short Term Revolving Credit Extension
Date, it shall give written notice to that effect to the Administrative Agent
not less than forty-five (45) nor more than sixty (60) days prior to such Short
Term Revolving Credit Extension Date. Each Lender will use its best efforts to
respond to such request, whether affirmatively or negatively, within thirty (30)
days after receipt of such notice from the Administrative Agent. If the Borrower
shall have received affirmative responses from all the Lenders, such response to
be in the sole and absolute discretion of each Lender, then, subject to receipt
by the Borrower of counterparts of an agreement duly completed and signed by the
Borrower and each such Lender (a "Short Term Revolving Credit Extension
Agreement"), the Short Term Revolving Credit Termination Date shall be extended,
effective on such Short Term Revolving Credit Extension Date, for an additional
364-day period to the date stated on such Short Term Revolving Credit Extension
Agreement. If the Borrower shall not have received affirmative responses from
all Lenders the Short Term Revolving Credit Termination Date shall not be
extended. For purposes of this Subsection 2.8a, the failure of any Lender to
respond shall be deemed to be a negative response from such Lender.

       2.8b EXTENSION OF LONG TERM REVOLVING CREDIT TERMINATION DATE. The Long
Term Revolving Credit Termination Date may be extended, in the manner set forth
in this Subsection 2.8b, on January 5, 2002 and on each anniversary of such date

Revolving Credit Termination Date on any Long Term Revolving Credit Extension
Date, it shall give written notice to that effect to the Administrative Agent
not less than forty-five (45) nor more than sixty (60) days prior to such Long
Term Revolving Credit Extension Date. Each Lender will use its best efforts to
respond to such request, whether

                                       29

affirmatively or negatively, within thirty (30) days after receipt of such
notice from the Administrative Agent. If the Borrower shall have received
affirmative responses from all the Lenders, such response to be in the sole and
absolute discretion of each Lender, then, subject to receipt by the Borrower of
counterparts of an agreement duly completed and signed by the Borrower and each
such Lender (a "Long Term Revolving Credit Extension Agreement"), the Long Term
Revolving Credit Termination Date shall be extended, effective on such Long Term
Revolving Credit Extension Date, for an additional one-year period to the date
stated in such Long Term Revolving Credit Extension Agreement. If the Borrower
shall not have received affirmative responses from all Lenders the Long Term
Revolving Credit Termination Date shall not be extended. For purposes of this
Subsection 2.8b, the failure of any Lender to respond shall be deemed to be a
negative response from such Lender.

         2.9 SUBSTITUTION OR REPLACEMENT OF A LENDER. The Borrower shall have
the right (provided that at such time, no Event of Default and no Potential
Default has occurred and is continuing), in its sole discretion, to either:

             (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 2.11, upon three (3) days prior
         notice if the Loans outstanding include Revolving Credit Loans bearing
         interest under the Euro-Rate Option or the Bid 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 Commitments 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 Commitments 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 Section 2.5a or 2.5b;

             (ii) the obligation of such Lender to make Revolving Credit Loans
         which bear or are to bear interest under the Euro-Rate Option has been
         suspended pursuant to Subsection 2.5d; or

             (iii) such Lender has responded negatively to a request for
         extension of any Termination Date pursuant to Section 2.8.

                  Provided, any proposed substitute lending institution, which
is not a Lender prior to the Borrower's selection thereof, must be acceptable to
the Administrative Agent, whose consent shall not be unreasonably withheld, 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 Administrative Agent)
must be complied with.

       2.10 LOAN REPAYMENT. Each repayment of the Revolving Credit 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 Administrative
Agent by 11:00 A.M. (eastern time) on the day of the

                                       30
<PAGE>   37
proposed repayment, in the case of Revolving Credit Loans bearing interest at
the Base Rate or (ii) three (3) Business Days' prior oral or written notice to
the Administrative Agent, in the case of Revolving Credit Loans bearing interest
at the Adjusted Euro-Rate, followed immediately thereafter by the Borrower's
written confirmation to the Administrative Agent of any oral notice, may repay
the outstanding amount of the Revolving Credit 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 2.11 below. The Borrower may prepay any Portion of the
Revolving Credit Loans bearing interest at the Base Rate without premium or
penalty.

                  In the event that principal payments are received on a day on
which principal payments are due on Revolving Credit Loans and Bid Rate Loans
the principal payments shall be applied: first, to repay in full the principal
amount of the Revolving Credit Loans then due and payable, if any; and second,
to repay in full the principal amount of the Bid Rate Loans then due and
payable, if any.

                  Any repayment of the Loans shall increase, by the amount of
that repayment, the unborrowed balance of the applicable Commitment; it being
contemplated that the Borrower may repay and reborrow from time-to-time under
each Commitment until the applicable Termination Date. All Short Term Revolving
Credit Loans outstanding on the Short Term Revolving Credit Termination Date
shall become due and payable in full on such date. All Long Term Revolving
Credit Loans outstanding on the Long Term Revolving Credit Termination Date
shall become due and payable in full on such date.

       2.11 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
Revolving Credit Loans or any Bid Rate Loan on a day other than the last day of
the applicable Interest Period, (iii) the Borrower shall convert any Portion to

other than the last day of the relevant Interest Period, or (iv) 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 or Notice of Bid Rate Borrowing, 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.

       2.12 VOLUNTARY REDUCTION OF AVAILABILITY. At any time and from time to
time upon no less than two (2) Business Days prior written notice to the
Administrative Agent, the Borrower may terminate, in whole or in part, without
penalty, the then unused portion of the Short Term Revolving Credit Commitment
and/or the Long Term Revolving Credit Commitment, thereby causing a
corresponding abatement of the relevant Facility Fee. Each such reduction shall
be in a minimum principal amount of $5,000,000 or in integral multiples thereof.
The relevant Facility Fee shall cease to accrue with respect to any unused
portion of the Short Term Revolving Credit Commitment or the Long Term Revolving
Credit Commitment so terminated

                                       31
<PAGE>   38
on either (i) the date two (2) Business Days after receipt of such notice or
(ii) the date so designated in the written notice if such written notice sets
forth an effective date of such termination which is more than two (2) Business
Days after such notice is given to the Administrative Agent. Notice of
termination once given shall be irrevocable and the portion of the Short Term
Revolving Credit Commitment or the Long Term Revolving Credit Commitment so
terminated shall not be available for borrowing once such notice has been given
under the terms hereof. The Administrative Agent shall promptly notify each
Lender of its pro rata share of such terminated unused portion and the date of
each such termination.

       2.13 LOAN ACCOUNT. Each Lender shall open and maintain on its books a
Loan Account in the name of the Borrower with respect to Disbursements made,
repayments, prepayments, the computation and payment of interest and the
Facility Fee and the computation of other amounts due and sums paid and payable
to such Lender pursuant to this Article II. Such Loan Account shall be prima
facie evidence as to the amount at any time due to such Lender from the Borrower
pursuant to this Article II; provided, however, that the failure of a Lender to
make notations, or to make accurate notations, on its Loan Account including
without limitation notations with respect to interest and Facility Fees pursuant
to Section 2.7 shall not limit, expand or otherwise affect any obligations of
the Borrower hereunder.

       2.14 PAYMENT FROM ACCOUNTS MAINTAINED BY BORROWER. In the event that any
payment of principal, interest, Facility Fee or any other amount due to the
Lenders or the Administrative Agent under the Agreement, the Notes or the other
Loan Documents is not paid when due, the Administrative Agent is hereby
authorized to effect such payment by debiting any demand deposit account of the
Borrower maintained with the Administrative Agent (excluding however any special
purpose fiduciary accounts, which are designated as such at the time of their
creation, and 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 Administrative Agent hereunder or by operation of
law.

       2.15 TIME, PLACE AND MANNER OF PAYMENTS. All payments to be made by the
Borrower under the Notes (other than those provided for in Sections 2.5 and 2.11
hereof), and of all fees and any other amounts due hereunder (excepting the
Closing Fee, the Agent's Fees and the Arrangement Fee) shall be made at the
principal office of the Administrative Agent for the ratable account of the
Lenders. The Administrative 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 2.5 or 2.11 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 available funds no later than 1:00 P.M. (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.

thereto; provided, however, that for purposes of this Agreement, neither the
Borrower nor the relevant Subsidiary shall be required to pay any tax,
assessment, charge or levy (i) the payment of which is being contested in good
faith by appropriate and lawful proceedings diligently conducted and (ii) as to
which the Borrower shall have set aside on its books reserves for such claims as
are determined to be adequate pursuant to the accounting procedures employed by
the Borrower, but only to the extent that failure to discharge any such
liabilities would not result in any additional liability which would have a
Material Adverse Effect upon the Borrower and its Subsidiaries taken as a whole.

Subsidiary to keep and maintain, insurance with responsible insurance companies,

by similar businesses similarly situated and owning, leasing or operating
similar properties. The Borrower may satisfy the requirements of the preceding
sentence with self insurance and deductibles consistent with customary and
prudent industry standards, all as reasonably satisfactory to the Administrative
Agent. The Borrower will furnish to the Administrative Agent at the Closing and
together with the annual reports delivered pursuant to Subsection 4.2(ii)
hereof, a certificate of an Authorized Officer of the Borrower certifying that
such insurance is in force, is adequate in nature and amount and complies with
the Borrower's and each Subsidiary's obligations under this Section 4.7.

       4.8 MAINTENANCE OF PROPERTIES. The Borrower shall and shall cause its
Subsidiaries to maintain, preserve, protect and keep their respective properties
in good repair, working order and condition (ordinary wear and tear excepted),
and make all necessary and proper repairs, renewals and replacements so that
their business carried on in connection therewith may be properly and
advantageously conducted at all times, except where the failure to maintain,
preserve, protect or keep such properties would not have a Material Adverse
Effect.

       4.9 PLANS AND BENEFIT ARRANGEMENT. The Borrower shall, and shall cause
each ERISA Affiliate to, comply with ERISA, the Code and all other applicable
laws which are applicable to Plans, except where the failure to do so, alone or
in conjunction with any other failure to do so, would not have a Material
Adverse Effect.

a majority of the individuals who were directors of the Borrower on the first
day of such period or their duly appointed or elected successors.

       7.11 CONSEQUENCES OF AN EVENT OF DEFAULT. If one or more of the Events of
Default occur then (a) if such Event of Default is set forth in Sections 7.3 or
7.4, the Commitments shall automatically terminate and the Notes then
outstanding shall become immediately due and

                                       45
<PAGE>   52
payable, without necessity of demand, presentation, protest, notice of dishonor
or notice of default; or (b) if such Event of Default is set forth in any of the
remaining Sections of this Article VII, then the Administrative Agent, at the
request of the Required Lenders, and without notice to the Borrower, shall
declare the Borrower in default hereunder, and upon such declaration, shall, at
the request of the Required Lenders, terminate the Commitments and/or declare
the Notes then outstanding immediately due and payable, without necessity of any
further demand, presentation, protest, notice of dishonor or further notice of

this Agreement and all those rights and remedies granted by law to creditors,
and the Administrative 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 other Loan
Documents, or for an injunction against a violation of any of the terms hereof
or thereof, or in aid of the exercise of any power granted hereby or thereby or
by law. No right, power or remedy conferred by this Agreement, in the Notes, or
by any other Loan Document, upon the Administrative Agent or the Lenders shall
be exclusive of any other right, power or remedy referred to herein or therein
or now or hereafter available at law, in equity, by statute or otherwise. No
exercise of any one right or remedy shall be deemed a waiver of other rights or
remedies. The rights and remedies of the Administrative Agent and the Lenders
specified herein are for the sole and exclusive benefit, use and protection of
the Administrative Agent and the Lenders, and the Administrative Agent and the
Lenders shall be entitled, but shall have no duty or obligation, to exercise or
to refrain from exercising any right or remedy reserved to the Administrative
Agent or the Lenders hereunder.

       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 Administrative Agent under this Agreement, the
Notes and the other Loan Documents. As such Administrative 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
Administrative Agent, by the terms hereto or thereof, together with such other
powers as are incidental thereto. Without limiting the foregoing, the
Administrative Agent, on behalf of the Lenders, 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.

       8.2 DELEGATION OF DUTIES. The Administrative 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 Administrative 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.

                                       46

       8.3 RELIANCE BY ADMINISTRATIVE AGENT ON LENDERS FOR FUNDING. Unless the
Administrative Agent shall have received notice from a Lender prior to any
Borrowing Date that such Lender will not make available to the Administrative
Agent such Lender's portion of net disbursements of Loans, the Administrative
Agent may assume that such Lender has made such portion available to the
Administrative Agent and the Administrative 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 Administrative Agent on or prior to
any Borrowing Date, such Lender and the Borrower severally agree to repay to the
Administrative 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 Administrative
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 Administrative 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 Administrative 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.

       8.4 NON-RELIANCE ON ADMINISTRATIVE AGENT. Each Lender agrees that it has,
independently and without reliance on the Administrative 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 Administrative 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 Administrative 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 document or instrument referred to or provided for herein
or to inspect the properties or books of the Borrower. The Administrative 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 ADMINISTRATIVE AGENT AND OTHER MATTERS.

       8.5a MINISTERIAL NATURE OF DUTIES. As among the Lenders and the
Administrative Agent, the Administrative 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 Administrative Agent shall be ministerial and administrative
in nature.

       8.5b LIMITATION OF LIABILITY. As among the Lenders and the Administrative
Agent, neither the Administrative 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 Administrative 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 Administrative 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

                                       47
<PAGE>   54
other Loan Documents or (B) any other document or instrument furnished pursuant
to or in connection with this Agreement, (ii) the collectibility of any amounts
owed by the Borrower to the Lenders, (iii) the truthfulness of any recitals,
statements, representations or warranties made to the Administrative Agent 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,
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 (v) the assets, liabilities, financial
condition, results of operations or business, or creditworthiness of the
Borrower.

       8.5c RELIANCE. The Administrative 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 Administrative Agent in good faith to be
genuine and correct and to have been signed or sent or made by a proper Person.
The Administrative 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 Administrative 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 Administrative Agent with
reasonable care. The Administrative 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 ADMINISTRATIVE AGENT; INSTRUCTIONS FROM THE
LENDERS. The Administrative 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 Administrative Agent's rights, powers or
discretion herein or under any Loan Documents, provided that the Administrative
Agent shall not be required to take any action which exposes the Administrative
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 Administrative 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 Section 8.5b hereof. Subject to the
provisions of Section 8.5b, no Lender shall have any right of action whatsoever
against the Administrative Agent as a result of the Administrative 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 Administrative Agent according to the terms hereof for and
from all reasonable costs, expenses and disbursements in connection herewith,
such costs, expenses and disbursements shall be borne by the Lenders ratably in
accordance with each Lender's Ratable Share. Each Lender hereby agrees on such
basis (i) to reimburse the Administrative Agent 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 pro rata share, to indemnify and save harmless
the Administrative 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

                                       48
<PAGE>   55
Administrative Agent, other than as a consequence of gross negligence or willful
misconduct on the part of the Administrative 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 connection
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 ADMINISTRATIVE AGENT'S RIGHTS AS A LENDER. With respect to the
Commitments of the Administrative Agent as a Lender hereunder, and any Loans of
the Administrative 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 Administrative Agent under this Agreement, the
Administrative 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 Administrative Agent. The Administrative Agent may accept deposits
from, lend money to, and generally engage, and continue to engage, in any kind
of business with the Borrower as if it were not the Administrative Agent.

       8.9 PAYMENT TO LENDERS. Except as otherwise set forth in Section 8.3
hereof, promptly after receipt from the Borrower of any principal repayment of
the Loans, interest due on the Loans and any Facility Fees owing to the Lenders
or other amounts due under any of the Loan Documents (except for such amounts
which are payable for the sole account of any Lender or the Administrative
Agent), the Administrative 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, all interest and principal payments on the Revolving Credit Loans and
all Facility Fees are to be divided pro rata among the Lenders 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. 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.

       8.11  SUCCESSOR ADMINISTRATIVE AGENT.

       8.11a RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent hereunder by giving thirty (30) days' prior
written notice to the Lenders and the Borrower. If such notice shall be given,
the Lenders shall appoint a successor agent for 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

                                       49
<PAGE>   56
successor, the Administrative Agent shall use reasonable commercial efforts to
procure a successor reasonably satisfactory to the Lenders and the Borrower, to
serve as agent for the Lenders hereunder and under the several Loan Documents.
Any such successor agent shall succeed to the rights, powers and duties of the
Administrative Agent.

       8.11b RIGHTS OF THE FORMER ADMINISTRATIVE AGENT. Upon the appointment of
such successor agent or upon the expiration of such thirty (30) day period (or
any longer period to which the Administrative Agent has agreed), the former
Administrative Agent's rights, powers and duties as Administrative Agent shall
be terminated, without any other or further act or deed on the part of such
former Administrative Agent or any of the parties to this Agreement. After any
retiring Administrative Agent's resignation hereunder as Administrative Agent
hereunder, the provisions of this Article VIII shall inure to the benefit of
such retiring Administrative Agent as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement.

       8.12 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of an Event of Default unless the
Administrative 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".

       8.13 NOTICES. The Administrative Agent shall promptly send to each Lender
a copy of all notices received from the Borrower pursuant to the provisions of
this Agreement or the other Loan Documents promptly upon receipt thereof. The
Administrative Agent shall promptly notify the Borrower and the other Lenders of
each change in the Base Rate and the effective date thereof.

       8.14 HOLDERS OF NOTES. The Administrative Agent may deem and treat any
payee of any Note as the owner thereof for all purposes hereof unless and until
written notice of the assignment or transfer thereof shall have been filed with
the Administrative Agent. 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.

       8.15 CALCULATIONS. In the absence of gross negligence or willful
misconduct, the Administrative Agent shall not be liable for any error in
computing the amount payable to any Lender whether in respect of the Loans, Fees
or any other amounts due to the Lenders under this Agreement. In the event an
error in computing any amount payable to any Lender is made, the Administrative
Agent, the Borrower and each affected 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 IX are solely for the benefit of the Administrative 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, the Administrative 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.

Section 9.1, the Administrative Agent, the Lenders and the Borrower may, from
time to time, enter into amendments, extensions, renewals, modifications,
supplements and replacements to and of this Agreement, the Notes or the other

from time to time, waive compliance with a provision thereof. No amendment,
renewal, modification, extension, supplement, replacement or waiver of any
provision of the Agreement, the Notes or the other Loan Documents or consent to

the written consent of the Required Lenders), and then such waiver or consent
shall be effective only for the specific instance and for the specific purpose
for which it is given; provided, however, that no amendment, renewal,
modification, waiver or consent, unless in writing and signed by all of the
Lenders (or the Administrative Agent with the written consent of all of the
Lenders), shall do any of the following:

         Agreement, change any Lender's Short Term Revolving Credit Commitment
         Percentage or Long Term Revolving Credit Commitment Percentage or the
         aggregate or individual unpaid principal amount of the Notes, or

         Fee, or any other obligations of the Borrower set forth in Article II;

                           (F) reduce any Facility Fee; or

                           (G) amend the definition of the term "Required
Lenders" or amend or waive the provisions of this Section 9.1.

Any such supplemental agreement shall apply equally to the Borrower and each of
the Lenders and shall be binding upon the Borrower, the Lenders, the
Administrative Agent and all future holders of the Notes. In the case of any
waiver, the Borrower, the Lenders and the Administrative Agent shall be restored

       9.2                 EXPENSES.  The Borrower shall pay:

applicable tax treaty or (ii) IRS Form W-8 or such other applicable form
prescribed by the IRS or a certificate of such Lender or assignee or participant
of a Lender indicating that no such exemption or reduced rate of taxation is
allowable with respect to such payments. Each Lender or assignee or participant
of a Lender which delivers an IRS Form W-8, W-9, 4224 or 1001 further undertakes
to deliver to the Administrative Agent and the Borrower two (2) additional
copies of any such form (or any successor form) on or before the date on which
that form expires or becomes obsolete 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
requested by the Borrower or the Administrative Agent, either certifying that
such Lender or assignee or participant of a Lender is entitled to receive
payments under this Agreement or its 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 the date on which that no such
exemption or reduced rate is allowable. The Administrative Agent shall be
entitled to withhold, from each payment hereunder or under the Notes payable to
it, United States federal income taxes at the full withholding rate unless each
Lender referred to in the first sentence of this Section 9.4 establishes an
exemption or at the applicable reduced rate established pursuant to the above
provisions.

       9.5 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
Borrower, the Administrative Agent and the Lenders and their respective
successors and assigns, and shall inure to the benefit of the Borrower, the
Administrative Agent and the Lender and the successors and assigns of the
Administrative 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 ASSIGNMENTS. Subject to the remaining provisions of this Subsection
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
to one or more financial institutions (individually a "Purchasing Lender"), a
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 "I" executed by the Transferor Lender, such
Purchasing Lender, the Borrower (if Borrower's consent is required for such
transfer as provided below) and the Administrative Agent; subject, however to
the following requirements:

           (i) Each such assignment must be in a minimum amount of $5,000,000,
       or, if in excess thereof, in integral multiples of $1,000,000, unless
       such Lender's Commitment is less than $5,000,000, in which case such
       assignment shall be in the full amount of such Lender's Commitment;

           (ii) During the first ninety (90) days following the Closing Date,
       each assignment made shall become effective only on a date which
       coincides with the expiration date of any Euro-Rate Interest Period then
       in effect, unless the Administrative Agent agrees to waive this
       provision;

           (iii) The Administrative 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 the occurrence of additional costs to
       the Borrower under Article II, or (B) the proposed assignee has not
       provided to the Borrower any tax forms received 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) Each such assignment shall be of a constant, and not a varying,
       percentage of the Transferor Lender's Ratable Share of the Commitments,
       outstanding Loans and all other rights and obligations under this
       Agreement and the other Loan Documents; and

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

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

                                       55
<PAGE>   62
hereunder with a Commitment 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 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 its Notes. On or prior to the Transfer Effective Date,
the Borrower shall execute and deliver to the Administrative 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 Commitments 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 Commitments 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 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 Administrative 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 names and addresses of the Lenders 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 Administrative Agent and
the Lenders may treat each Person whose name is recorded in the Register as the
owner of the Loans recorded therein for all purposes of this Agreement. The
Register shall be available at the office of the Administrative 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 owing to such
Lender, the interest of such Lender in any Notes or the Commitments 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 Notes for all purposes under this Agreement and the Borrower, the
other Lenders and the Administrative 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
Administrative 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

                                       56
<PAGE>   63
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 Commitments 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 Section 9.6d, such SPC may (i) with prior written
consent of the Borrower and the Administrative Agent (such consent not to be
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 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 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.

       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 State of New Jersey 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.

                                       57
<PAGE>   64

       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.

       9.12 HEADINGS. Article, Section and other headings used in this Agreement
are intended for convenience only and shall not affect the meaning or
construction of this Agreement.

       9.13 SET-OFF. The Borrower hereby gives to the Lenders a lien and
security interest for the amount of any Bank Indebtedness upon and in any
property, 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 nonexclusive 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.

       9.15 WAIVER OF JURY TRIAL. Each of the Administrative Agent, the Lenders
and the Borrower hereby knowingly, voluntarily and intentionally waive any
rights they may have to a trial by jury in respect of any litigation based
hereon, or arising out of, 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 Administrative 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
Administrative 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 incurred by any such Person in connection with the
preparation for

                                       58
<PAGE>   65
or defense of any pending or threatened claim, action or proceeding) suffered or
incurred by any of them under any applicable federal or state law or otherwise
caused by, arising out of, resulting from or in any manner connected with, the
execution, delivery and performance of each of the Loan Documents, the Loans and
any and all transactions related to or consummated in connection with the Loans.
The indemnity set forth in this Section 9.16 shall be in addition to any other
obligations or liabilities of the Borrower to the Administrative 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
Administrative 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 Administrative 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
Administrative Agent's, or such Lender's gross negligence or willful misconduct.
All amounts owed pursuant to this Section 9.16 shall be part of the Bank
Indebtedness.

       9.17 COUNTERPARTS. This Agreement and any amendment, modification,
extension or 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, shall be an original, but all of which together shall constitute but
one and the same instrument. In proving this Agreement or any amendment,
modification, 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.

       9.18 CONFIDENTIALITY. Each Lender agrees to maintain in confidence and
not to disclose without the Borrower's consent (other than to its employees,
affiliates, auditors, counsel or other professional advisors, or to another
Lender, each of which shall also be bound by this Section 9.18) any information
concerning the Borrower or its Subsidiaries furnished pursuant to this Agreement
and identified as confidential by the party so furnishing such information;
provided that any Lender may disclose any such information (a) that has become
generally available to the public, (b) if required or appropriate in any report,
statement or testimony submitted to any regulatory body having or claiming to
have jurisdiction over such Lender, (c) if required or appropriate in respect to
any summons or subpoena or in connection with any litigation, (d) in order to
comply with any law, order, regulation or ruling applicable to such Lender, or
(e) to any prospective or actual participant under Section 9.6 hereof in
connection with any contemplated or actual transfer of a participating or other
interest in such Lender's rights or liabilities hereunder; provided, that (i)
such actual or prospective transferee executes an agreement with such Lender
containing provisions substantially identical to those contained in this Section
9.18 and (ii) in the case of any disclosure under subsection (c) above, such
Lender shall (to the extent permitted by applicable law) notify the Borrower of
such disclosure so that the Borrower may seek an appropriate protective order or
waive such Lender's compliance with the provisions of this Section, it being
understood that if the Borrower has no right to obtain such a protective order
or if the Borrower does not commence procedures to obtain such a protective
order within ten (10) Business Days of the receipt of such notice, such Lender's
compliance with this Section shall be deemed to have been waived with respect to
such disclosure.
