                                   ----------

          In consideration of the mutual covenants and agreements herein set
forth and for other consideration, the receipt and sufficiency of which is
hereby acknowledged, and intending to be legally bound hereby, the parties
hereto hereby covenant and agree as follows:

                            SECTION 1. DEFINITIONS

          1.1  Defined Terms.  As used in this Agreement, the following terms

     indirectly, through one or more intermediaries, controls, or is controlled
     by, or is under common control with, such Person and any member, director,
     officer or employee of any such Person.  For purposes of this definition,
     "control" shall mean the power, directly or indirectly, either to (a) vote
     10% or more of the ordinary voting power for the election of directors of
     such Person or (b) direct or in effect cause the direction of the
     management and policies of such Person whether by contract or otherwise.

     otherwise modified from time to time.

     effect on such day plus  1/2%.  If for any reason the Agent shall have

     determined without regard to clause (b) of the first
<PAGE>

     inability no longer exist. Any change in the Base Rate due to a change in
     the Prime Rate or the Federal Funds Effective Rate shall be effective on

     Effective Rate, respectively.

loans in Dollars (the "Revolving Credit Loans") to the Borrower from time to
                       ----------------------
time during the Commitment Period, in an aggregate principal amount at any time
outstanding which, when added to such Bank's Commitment Percentage of (i) the
L/C Obligations then outstanding and (ii) the principal amount of Swing Line
Loans then outstanding, does not exceed such Bank's Commitment; provided, that
                                                                --------
at no time shall the sum of (x) the aggregate principal amount of all Loans made

time to time pursuant to Section 2.10. Within the foregoing limits, the Borrower
may during the Commitment Period borrow, repay and reborrow under the
Commitment, subject to the terms, provisions and limitations set forth herein.

               (b) The Revolving Credit Loans may from time to time be (i)
Eurodollar Loans, (ii) Base Rate Loans or (iii) a combination thereof, as

2.2 and 2.18; provided, that no Loan shall be made as a Eurodollar Loan after
              --------

               (c) The failure of any Bank to make any Revolving Credit Loan
shall not in itself relieve any other Bank of its obligation to lend hereunder
(it being understood, however, that no Bank shall be responsible for the failure
of any other Bank to make any Loan required to be made by such other Bank). The
Loans comprising any Revolving Credit Borrowing shall be (i) with respect to a
Base Rate Borrowing, in a minimum aggregate principal amount of $100,000 or a
whole multiple thereof or (ii) with respect to a Eurodollar Borrowing, in a
minimum aggregate principal amount of $500,000 or a whole multiple of $100,000
in excess thereof (or, in either case, an aggregate principal amount equal to
the remaining balance of the available Commitments).

Revolving Credit Borrowing (which shall be a Business Day); (iii) the principal
amount of such Borrowing; and (iv) if such Borrowing is to be a Eurodollar
Borrowing, the Interest Period with respect thereto. If no election as to the
Type of Revolving Credit Borrowing is specified in any such notice, then the
requested Revolving Credit Borrowing shall be a Base Rate Borrowing. If no
Interest Period with respect to any Eurodollar Borrowing is specified in any
such notice, then the Borrower shall be deemed to have selected an

                                       17

Line Commitment and substantially in the form of Exhibit B-2 (as amended,
                                                 -----------
supplemented or otherwise modified from time to time, the "Swing Line Note").
                                                           ---------------

               (d) Interest shall accrue on the outstanding principal balance of
a Swing Line Loan at the Base Rate Option and shall be payable on each
applicable Interest Payment Date and upon the repayment of such Swing Line Loan.

               (e) A Swing Line Loan shall be repaid on the earlier of (i) the
Termination Date and (ii) the Swing Line Repayment Date for such Swing Line
Loan, if any.

               (f) In the event the Commitments are terminated in accordance
with Section 2.10 hereof, the Swing Line Commitment shall also be terminated
automatically. In the event the Borrower reduces the Total Commitment to less
than the Swing Line Commitment, the Swing Line Commitment shall immediately be
reduced to an amount equal to the Total Commitment. In the event the Borrower
reduces the Total Commitment to less than the outstanding principal amount of
the Swing Line Loans, the Borrower shall immediately repay the

                                       18

amount by which the outstanding Swing Line Loans exceed the Swing Line
Commitment as so reduced plus accrued interest thereon.

               (g)   At no time shall there be more than one outstanding Swing
Line Loan.

               (h)   Each Swing Line Loan shall be in an original principal
amount of $100,000 or a whole multiple thereof.

               (i)   The Borrower shall have the right at any time and from time
to time to prepay any Swing Line Loan, in whole or in part, without premium or
penalty, upon prior written, telecopy or telephonic notice to the Swing Line
Bank given no later than 1:00 p.m., Wilmington time, on the date of any proposed
prepayment. Each notice of prepayment shall specify the Swing Line Loan to be
prepaid and the amount to be prepaid, shall be irrevocable and shall commit the
Borrower to prepay such amount on such date, with accrued interest thereon.

          2.4  General Provisions Regarding Loans. (a) Subject to Section
               ----------------------------------
2.4(b), each Bank shall make each Revolving Credit Loan to be made by it
hereunder on the proposed date thereof by wire transfer of immediately available
funds to the Agent in Pittsburgh, Pennsylvania not later than 3:00 p.m.,
Wilmington time, and the Agent shall by 4:00 p.m., Wilmington time, credit the
amounts so received to the general deposit account of the Borrower with the
Agent or, if a Borrowing shall not occur on such date because any condition
precedent herein specified shall not have been met, return the amounts so
received to the respective Banks. Revolving Credit Loans shall be made by the
Banks pro rata in accordance with Section 2.16. Unless the Agent shall have
      --- ----
received notice from a Bank prior to the date of any Borrowing that such Bank
will not make available to the Agent such Bank's portion of such Borrowing, the
Agent may assume that such Bank has made such portion available to the Agent on
the date of such Borrowing in accordance with this paragraph (a) and the Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent that such Bank shall not have
made such portion available to the Agent, such Bank and the Borrower severally
agree to repay to the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Agent at
(i) in the case of the Borrower, the interest rate applicable at the time to the
Loans comprising such Borrowing and (ii) in the case of such Bank, the Federal
Funds Effective Rate; provided, that if such Bank shall not pay such amount
                      --------
within three Business Days of the date of such Borrowing, such overdue amount
shall, at the expiration of such three-Business Day period, bear interest at the
Base Rate Option. If such Bank repays to the Agent such corresponding amount,
such amount shall constitute such Bank's Loan as part of such Borrowing for
purposes of this Agreement.

               (b) The Borrower may refinance all or any part of any Borrowing
with any other Borrowing subject to the conditions and limitations set forth
herein and elsewhere in this Agreement. Any Borrowing or part thereof so
refinanced shall be deemed to be repaid in accordance with Section 2.3 or 2.7
with the proceeds of a new Borrowing hereunder and the proceeds of the new
Borrowing, to the extent they do not exceed the principal amount of the

                                       19
<PAGE>

Borrowing being refinanced, shall not be paid by the Banks to the Agent or by
the Agent to the Borrower; provided, however, that (i) if the principal amount
                           --------  -------
extended by a Bank in a refinancing is greater than the principal amount that
was extended by such Bank in the Borrowing being refinanced, then such Bank
shall pay such difference to the Agent for distribution to the Banks described
in (ii) below, (ii) if the principal amount extended by a Bank in the Borrowing
being refinanced is greater than the principal amount agreed to be extended by
such Bank in the refinancing, the Agent shall return the difference to such Bank
out of amounts received pursuant to (i) above, and (iii) to the extent any Bank
fails to pay the Agent amounts due from it pursuant to (i) above, any Loan or
portion thereof being refinanced with such amounts shall not be deemed repaid in
accordance with Section 2.3 or 2.7 and shall be payable by the Borrower without
prejudice to the Borrower's rights against any such Bank.

               (c)  Each Bank may at its option fulfill its Commitment hereunder
with respect to any Eurodollar Loan by causing any domestic or foreign branch or
Affiliate of such Bank to make such Loan; provided, however, that any exercise
                                          --------  -------
of such option shall not affect the obligation of the Borrower to repay such
Loan in accordance with the terms of the Agreement and the applicable Note.

               (d)  All Borrowings, conversions and continuations of Revolving
Credit Loans hereunder and all selections of Interest Periods hereunder shall be
in such amounts and be made pursuant to such elections that, after giving effect
thereto, (A) the aggregate principal amount of the Loans comprising each Tranche
of Eurodollar Loans shall be equal to $500,000 or a whole multiple of $100,000
in excess thereof and (B) the Borrower shall not have outstanding at any one
time more than in the aggregate eight (8) separate Tranches of Loans (including
the Base Rate Tranche).

               (e)  Notwithstanding any other provision of this Agreement, the
Borrower shall not be entitled to request any Borrowing if the Interest Period
requested with respect thereto would end after the Termination Date.

          2.5  Letters of Credit.
               -----------------

               (a)  L/C Commitment. (i) Subject to the terms and conditions
                    --------------
hereof, the Issuing Bank, in reliance on the agreements of the other Banks set
forth in Section 2.5(d), agrees to issue letters of credit (together with the
Existing Letters of Credit, collectively referred to as the "Letters of Credit")
                                                             -----------------
for the account of the Borrower on any Business Day during the Commitment Period
in such form as may be approved from time to time by the Issuing Bank; provided,
                                                                       --------
that no Letter of Credit shall be issued if, after giving effect thereto (A) the
amount of the Total Exposure would exceed the amount of the Total Commitment in
effect at such time or (B) the aggregate amount of the L/C Obligations at such
time would exceed the L/C Commitment in effect at such time.

                    (ii)  Each Letter of Credit:

                          (A)  shall be denominated in Dollars and shall be a
     standby letter of credit; and

                                       20
<PAGE>

                                   (B)  shall be for the account of the
     Borrower and for the benefit of the Borrower and/or one or more of the
     Guarantors;

                                   (C)  shall have an expiration date no later
     than the Termination Date; and

                                   (D)  may during the Commitment Period be
     extended at the sole discretion of the Issuing Bank for additional periods
     of up to one year each (but in no event to expire later than the
     Termination Date) upon written request from the Borrower to the Issuing
     Bank at least 20 days (or such other time period as agreed by the Borrower
     and the Agent) before the date upon which notice of extension is otherwise
     required by the terms thereof.

                         (iii)     Each Letter of Credit shall be subject to
     ISP98 and, to the extent not inconsistent therewith, the laws of the State
     of Delaware.

                    (b)  Procedure for Issuance of Letters of Credit. The
                         -------------------------------------------
Borrower may from time to time request that the Issuing Bank issue a Letter of
Credit by delivering to the Issuing Bank at its office for notices specified
herein an Application therefor, completed to the satisfaction of the Issuing
Bank, and such other certificates, documents and other papers and information as
the Issuing Bank may reasonably request. Upon receipt by the Issuing Bank of any
Application, the Issuing Bank will process such Application and the
certificates, documents and other papers and information delivered to it in
connection therewith in accordance with its customary procedures and shall,
after determining from the Agent that issuance of the Letter of Credit requested
thereby will be within the limits imposed by Section 2.5(a)(i), issue such
Letter of Credit not later than ten (10) Business Days after its receipt of the
Application therefor and all such other certificates, documents and other papers
and information relating thereto (but in no event shall the Issuing Bank be
required to issue any Letter of Credit earlier than five (5) Business Days after
its receipt of the Application therefor and all such other certificates,
documents and other papers and information relating thereto) by issuing the
original of such Letter of Credit to the beneficiary thereof or as otherwise may
be agreed by the Issuing Bank and the Borrower. The Issuing Bank shall promptly
after issuing a Letter of Credit furnish copies thereof to the Borrower.

                    (c)  L/C Fees, Commissions and Other Charges. (i) The
                         ---------------------------------------
     Borrower shall pay to the Agent, for the account of the Banks (including
     the Issuing Bank) pro rata according to their respective Commitment
                       --- ----
     Percentages, a letter of credit fee with respect to the aggregate face
     amount of all Letters of Credit outstanding, computed at the rate of three
     quarters of one percent (.75%) (computed on the basis of the actual number
     of days each Letter of Credit is outstanding in a year of 360 days). The
     Borrower shall also pay to the Issuing Bank, in respect of each Letter of
     Credit issued by the Issuing Bank, a fronting fee in an amount not to
     exceed $250. The fees described in the preceding sentences shall be due and
     payable quarterly in arrears on each L/C Payment Date and on the
     Termination Date or such earlier date as the Commitments are terminated,
     and shall be nonrefundable.

                                       21
<PAGE>

                         (ii)   In addition to the foregoing fees, the Borrower
     shall pay or reimburse the Issuing Bank for such normal and customary costs
     and expenses as are incurred or charged by the Issuing Bank in issuing,
     effecting payment under, amending or otherwise administering any Letter of
     Credit, in accordance with the schedule of such costs attached hereto as
     Schedule IV.
     -----------

                         (iii)  The Agent shall, promptly following its receipt
     thereof, distribute to the Issuing Bank and the Banks all fees and
     commissions received by the Agent for their respective accounts pursuant to
     this subsection.

                    (d)  L/C Participations.  (i) The Issuing Bank irrevocably
                         ------------------
     agrees to grant and hereby grants to each L/C Participant, and, to induce
     the Issuing Bank to issue Letters of Credit hereunder, each L/C Participant
     irrevocably agrees to accept and purchase and hereby accepts and purchases
     from the Issuing Bank, on the terms and conditions hereinafter stated, for
     such L/C Participant's own account and risk, an undivided interest equal to
     such L/C Participant's Revolving Credit Commitment Percentage in the
     Issuing Bank's obligations and rights under each Letter of Credit issued by
     the Issuing Bank hereunder and the amount of each draft paid by the Issuing
     Bank thereunder. Each L/C Participant unconditionally and irrevocably
     agrees with the Issuing Bank that, if a draft is paid under any Letter of
     Credit issued by the Issuing Bank for which the Issuing Bank is not
     reimbursed in full by the Borrower in accordance with the terms of this
     Agreement, such L/C Participant shall pay to the Issuing Bank upon demand
     at the Issuing Bank's address for notices specified herein an amount equal
     to such L/C Participant's Revolving Credit Commitment Percentage of the
     amount of such draft or any part thereof, which is not so reimbursed. Any
     action taken or omitted by the Issuing Bank under or in connection with a
     Letter of Credit, if taken or omitted in the absence of gross negligence or
     willful misconduct, shall neither create for the Issuing Bank any resulting
     liability to any L/C Participant nor constitute a defense to an L/C
     Participant's obligation to make the payments to the Issuing Bank required
     by the immediately preceding sentence.

                         (ii)   If any amount required to be paid by any L/C
     Participant to the Issuing Bank pursuant to Section 2.5(d) in respect of
     any unreimbursed portion of any payment made by the Issuing Bank under any
     Letter of Credit is not paid to the Issuing Bank on the date such payment
     is due from such L/C Participant, such L/C Participant shall pay to the
     Issuing Bank on demand an amount equal to the product of (A) such amount,
     times (B) the daily average Federal Funds Effective Rate, as quoted by the
     Issuing Bank, during the period from and including the date such payment is
     required to the date on which such payment is immediately available to the
     Issuing Bank, times (C) a fraction the numerator of which is the number of
     days that elapse during such period and the denominator of which is 360. A
     certificate of the Issuing Bank submitted to any L/C Participant with
     respect to any amounts owing under this subsection shall be conclusive in
     the absence of manifest error.

                                       22
<PAGE>

                         (iii) Whenever, at any time after the Issuing Bank has
     made payment under any Letter of Credit and has received from any L/C
     Participant its pro rata share of such payment in accordance with Section
     2.5(d)(i), the Issuing Bank receives any payment related to such Letter of
     Credit (whether directly from the Borrower or otherwise, including by way
     of set-off or proceeds of collateral applied thereto by the Issuing Bank),
     or any payment of interest on account thereof, the Issuing Bank will
     distribute to such L/C Participant its pro rata share thereof; provided,
                                            --- ----                --------
     however, that in the event that any such payment received by the Issuing
     -------
     Bank shall be required to be returned by the Issuing Bank, such L/C
     Participant shall return to the Issuing Bank the portion thereof previously
     distributed by the Issuing Bank to it.

                    (e)  Reimbursement Obligation of the Borrower. (i) The
                         ----------------------------------------
     Borrower agrees to reimburse the Issuing Bank in respect of a Letter of
     Credit on each date on which the Issuing Bank notifies the Borrower of the
     date and amount of a draft presented under such Letter of Credit and paid
     or to be paid by the Issuing Bank for the amount of (A) such draft so paid
     and (B) any taxes, fees, charges or other direct out of pocket costs or
     expenses incurred by the Issuing Bank in connection with such payment. Each
     such payment shall be made to the Issuing Bank at its office listed in
     Section 9.2 in Dollars and in immediately available funds.

                         (ii)  Interest shall be payable on any and all amounts
     remaining unpaid by the Borrower under this subsection from the date such
     amounts become payable (whether at stated maturity, by acceleration or
     otherwise) until payment in full at the per annum rate of the Base Rate
     Option plus 2.0% and shall be payable on demand by the Issuing Bank.

                    (f)  Obligations Absolute. (i) The obligations of the
                         --------------------
     Borrower under this Section 2.5 shall be absolute and unconditional under
     any and all circumstances and irrespective of any set-off, counterclaim or
     defense to payment which the Borrower may have or have had against the
     Issuing Bank or any beneficiary of a Letter of Credit or any other Person.

                         (ii)  The Borrower agrees with the Issuing Bank that
     the Issuing Bank shall not be responsible for, and the Borrower's
     Reimbursement Obligations under Section 2.5(e) shall not be affected by,
     among other things, (A) the validity or genuineness of any documents or of
     any endorsements thereon, even though such documents shall in fact prove to
     be invalid, fraudulent or forged, provided, that reliance upon such
                                       --------
     documents by the Issuing Bank shall not have constituted gross negligence
     or willful misconduct by the Issuing Bank or (B) any dispute between or
     among the Borrower and any beneficiary of any Letter of Credit or any other
     Person to which such Letter of Credit may be transferred or (C) any claims
     whatsoever of the Borrower against any beneficiary of such Letter of Credit
     or any such transferee.

                         (iii) The Issuing Bank shall not be liable for any
     error, omission, interruption or delay in transmission, dispatch or
     delivery of any message or

                                       23
<PAGE>

     advice, however transmitted, in connection with any Letter of Credit,
     except for errors or omissions caused by the Issuing Bank's gross
     negligence or willful misconduct.

                         (iv)  The Borrower agrees that any action taken or
     omitted by the Issuing Bank under or in connection with any Letter of
     Credit or the related drafts or documents, if done in the absence of gross
     negligence or willful misconduct, shall be binding on the Borrower and
     shall neither result in any liability of the Issuing Bank to the Borrower
     nor constitute a defense to the Borrower's obligation to reimburse the
     Issuing Bank.

                    (g)  Letter of Credit Payments. If any draft shall be
                         -------------------------
presented for payment to the Issuing Bank under any Letter of Credit, the
Issuing Bank shall promptly notify the Borrower of the date and amount thereof.
The responsibility of the Issuing Bank to the Borrower in connection with any
draft presented for payment under any Letter of Credit shall, in addition to any
payment obligation expressly provided for in such Letter of Credit, be limited
to determining that the documents (including each draft) delivered under such
Letter of Credit in connection with such presentment are in conformity with such
Letter of Credit.

                    (h)  Application.  To the extent that any provision of any
                         -----------
Application related to any Letter of Credit is inconsistent with the provisions
of this Agreement, the provisions of this Agreement shall apply.

               2.6  Fees. (a) The Borrower agrees to pay to the Agent for the
                    ----
account of each Bank a commitment fee (a "Commitment Fee") for the period from
                                          --------------
and including the first day of the Commitment Period to the Termination Date,
computed at a rate per annum equal to 1/4%, calculated on the basis of a 360 day
year for the actual days elapsed, on the average daily amount of the difference
between the Commitment of such Bank and its Exposure during the period for which
payment is made, payable quarterly in arrears on the last day of each March,
June, September and December and on the Termination Date or such earlier date as
the Total Commitment shall be permanently reduced or terminated as provided
herein, commencing on the first of such dates to occur after the Effective Date.
Each payment by the Borrower on account of the Commitment Fee shall be made pro
                                                                            ---
rata according to the Banks' respective Revolving Credit Commitment Percentages.
----

                    (b)  The Borrower agrees to pay to the Agent for the account
of each Bank pro rata in accordance with Section 2.16 a closing fee in the
             --- ----
amount of $62,500, payable on the Effective Date.

                    (c)  All fees shall be paid on the dates due, in immediately
available funds, to the Agent for distribution, if and as appropriate, among the
Banks. Once paid, none of the fees shall be refundable under any circumstances.

                    ------------------------------------------
Credit Loans made by each Bank shall be evidenced by a single Revolving Credit
Note duly executed on behalf of the Borrower, dated the Effective Date, in
substantially the form attached hereto as Exhibit B-1 with the blanks
                                          -----------
appropriately filled, payable to such Bank in a principal amount

                                       24
<PAGE>

equal to the Commitment of such Bank. Each Note shall bear interest from the
date thereof on the outstanding principal balance thereof as set forth in
Section 2.8. The outstanding principal balance of each Revolving Credit Loan, as
evidenced by the relevant Note, shall be payable on the Termination Date. The
Borrower hereby authorizes the Agent to charge any deposit account of the
Borrower maintained with the Agent for any payment when due hereunder or under
the Notes.

               2.8  Interest on Revolving Credit Loans.  (a) Subject to the
                    ----------------------------------
provisions of Section 2.9, each Base Rate Loan shall bear interest (computed on
the basis of the actual number of days elapsed over a year of 365 or 366 days,
as the case may be) at a rate per annum equal to the Base Rate minus 1% (the
                                                               -----

                    (b)  Subject to the provisions of Section 2.9, each
Eurodollar Loan shall bear interest (computed on the basis of the actual number
of days elapsed over a year of 360 days) at a rate per annum equal to the
Eurodollar Rate for the Interest Period in effect for such Loan plus 1.25% (the
                                                                ----
"Eurodollar Rate Option").

                    (c)  Interest on each Revolving Credit Loan shall be payable
on each Interest Payment Date applicable to such Loan; provided, that interest
                                                       --------
accruing on overdue amounts pursuant to Section 2.9 shall be payable on demand.
The Agent's calculation of the Eurodollar Rate and the Base Rate shall be
conclusive absent manifest error.

               2.9  Default Rate; Inability to Determine Interest Rate. (a)
                    --------------------------------------------------
Upon the occurrence of and during the continuance of an Event of Default under
Section 7.1(a) or (g), the outstanding principal amount of the Loans and, to the
extent permitted by law, accrued and unpaid interest thereon and any other
amount payable hereunder shall bear interest from the date of such occurrence
until paid in full (after as well as before judgment) at a rate per annum which
is equal to two percent (2%) in excess of the Base Rate Option. Upon the
occurrence of and during the continuance of an Event of Default other than under
Section 7.1(a) or (g), the outstanding principal amount of the Loans and, to the
extent permitted by law, accrued and unpaid interest thereon and any other
amount payable hereunder shall bear interest from the date that the Agent shall
send notice to the Borrower of the application of the default rate until paid in
full (after as well as before judgment) at a rate per annum which is equal to
two percent (2%) in excess of the Base Rate Option. The Borrower acknowledges
that such increased interest rate reflects, among other things, the fact that
such loans or other amounts have become a substantially greater risk given its
default status and that the Banks are entitled to additional compensation for
such risk.

                    (b)  In the event, and on each occasion, that prior to the
commencement of any Interest Period for a Eurodollar Loan, the Agent shall have
determined (which determination shall be conclusive and binding upon the
Borrower) that dollar deposits in the principal amount of such Eurodollar Loan
are not generally available in the London interbank market, or that the rate at
which such dollar deposits are being offered will not adequately and fairly
reflect the cost to the Banks of making or maintaining the principal amount of
such Eurodollar Loan during such Interest Period, or that reasonable means do
not exist for

                                       25
<PAGE>

ascertaining the Eurodollar Rate, the Agent shall, as soon as practicable
thereafter, give written, telegraphic or telephonic notice of such determination
to the Borrower and the Banks. After such notice shall have been given and until
the circumstances giving rise to such notice no longer exist, each request for a
Eurodollar Loan or for conversion to or maintenance of a Eurodollar Loan
pursuant to the terms of this Agreement shall be deemed to be a request for a
Base Rate Loan.

                    2.10 Termination, Reduction and Extension of Commitments.
                         ---------------------------------------------------
(a) The Total Commitment shall be automatically terminated on the Termination
Date.

                         (b)  Subject to the last sentence of this paragraph,
upon at least five Business Days' prior irrevocable written or telecopy notice
to the Agent, the Borrower may at any time in whole permanently terminate, or
from time to time permanently reduce, the Total Commitment. Each partial
reduction of the Total Commitment shall be in a minimum principal amount of
$5,000,000 or in whole multiples thereof, and no such termination or reduction
shall be made which would, after giving effect to any prepayments of Revolving
Credit Loans on such date reduce the Total Commitment to an amount less than the
amount of the Total Exposure.

                         (c)  Each reduction in the Total Commitment hereunder
shall be made ratably among the Banks in accordance with their respective
Commitment Percentages. The Borrower shall pay to the Agent for the account of
the relevant Banks, on the date of each termination or reduction, the Commitment
Fees on the amount of the Commitments so terminated or reduced accrued to the
date of such termination or reduction. In connection with any reduction of the
Total Commitment, the Borrower shall make any prepayment required under Section
2.11(b).

                         (d)  During the period beginning ninety days prior to
the then effective Termination Date and ending sixty (60) days prior to such
Termination Date, the Borrower may deliver to the Agent (which shall promptly
transmit to each Bank) a notice requesting that the Commitments be extended for
an additional nine months beyond the Termination Date then in effect. Within
forty-five days after its receipt of any such notice, each Bank shall notify the
Agent of its willingness or unwillingness to extend its Commitment. Any Bank
that shall fail to notify the Agent within such period shall be deemed to have
declined to extend its Commitment. If each (but only if each) Bank agrees to
extend its Commitment, the Agent shall so notify the Borrower and each Bank,
whereupon (i) the respective Commitments of the Banks shall without further act
by any party hereto, be extended to the date nine months after the Termination
Date then in effect and (ii) the term "Termination Date" shall thereafter mean
such date. Any such extension shall be evidenced by a written agreement among
the Agent, the Banks and the Borrower, such agreement to be in form and
substance acceptable to the Agent and the Banks. In the event that one or more
Banks (each a "Non-Electing Bank") shall have declined or been deemed to have
               -----------------
declined to extend its or their Commitment and Banks holding a majority in
amount of the Commitments shall have notified the Agent of their desire to
extend their Commitments, the Borrower shall have the right, but not the
obligation, at its own expense, upon notice to each such Non-Electing Bank and
the Agent, to replace all (but not less than all) such Non-Electing Banks (in
accordance with and subject to the restrictions contained in Section 9.6)

                                       26
<PAGE>

at any time before the thirtieth (30th) day prior to the Termination Date with
one or more assignees (each a "Replacement Bank") willing to purchase all of the
                               ----------------
Non-Electing Banks' interests hereunder and to agree to extend its or their
Commitment in accordance with the notice referred to in the first sentence of
this paragraph (d). In such event, each Non-Electing Bank shall promptly upon
request transfer and assign without recourse (in accordance with and subject to
the restrictions contained in Section 9.6) all its interests, rights and
obligations under this Agreement to the applicable Replacement Bank; provided,
                                                                     --------
however, that (i) no such assignment shall conflict with any law or any rule,
-------
regulation or order of any Governmental Authority, (ii) the applicable
Replacement Bank shall pay to the applicable Non-Electing Bank in immediately
available funds on the date of such assignment the principal of and interest
accrued to the date of payment on the Loans made by such Non-Electing Bank
hereunder and all other amounts accrued for such Non-Electing Bank's account or
owed to it hereunder (including Commitment Fees and any unpaid costs or
expenses), and (iii) a Non-Electing Bank shall not be required to sell its
interests hereunder unless the Borrower has arranged for one or more Replacement
Banks to acquire the interests of all other Non-Electing Banks. If, as a result
of the foregoing, each Bank (including Replacement Banks, but excluding Non-
Electing Banks whose interests have been purchased as provided above) has agreed
to extend its Commitment, the Commitments shall be extended as provided in
clause (i) of the fourth sentence of this paragraph and the term Termination
Date shall have the meaning set forth in clause (ii) in such fourth sentence of
this paragraph (d).

               2.11 Optional and Mandatory Prepayments of Revolving Credit
                    ------------------------------------------------------
Loans. (a) The Borrower shall have the right at any time and from time to time
-----
to prepay any Revolving Credit Borrowing, in whole or in part, without premium
or penalty (but in any event subject to Section 2.15), upon prior written,
telecopy or telephonic notice to the Agent given no later than 10:30 a.m.,
Wilmington time, one Business Day before any proposed prepayment; provided,
                                                                  --------
however, that each such partial prepayment shall be in the principal amount of
-------
at least (x) with respect to Base Rate Loans, $100,000 or in whole multiples
thereof and (y) with respect to Eurodollar Loans, $500,000 or in whole multiples
of $100,000 in excess thereof or, in either case, the entire amount outstanding,
whether or not divisible by $100,000.

                    (b)  On the date of any reduction of the Total Commitment
pursuant to Section 2.10, the Borrower shall pay or prepay so much of the
Revolving Credit Borrowings as shall be necessary in order that, after giving
effect to such reduction and any such payments, the Total Exposure at such time
will not exceed the Total Commitment.

                    (c)  Each notice of prepayment shall specify the prepayment
date and the principal amount of each Borrowing of Revolving Credit Loans to be
prepaid, shall be irrevocable and shall commit the Borrower to prepay such
Borrowing (or portion thereof) by the amount stated therein. All prepayments on
Eurodollar Loans under this Section shall be accompanied by accrued interest on
the principal amount being prepaid to the date of prepayment.

               2.12 Illegality.  Notwithstanding any other provision herein, if
                    ----------
any change in any Requirement of Law or in the interpretation or application
thereof shall make it unlawful for

                                       27
<PAGE>

any Bank to make or maintain Eurodollar Loans as contemplated by this Agreement,
(a) the commitment of such Bank hereunder to make or refinance Eurodollar Loans,
continue Eurodollar Loans as such and convert or refinance Base Rate Loans to
Eurodollar Loans shall forthwith be cancelled and (b) such Bank's Loans then
outstanding as Eurodollar Loans, if any, shall be converted automatically to
Base Rate Loans on the respective last days of the then current Interest Periods
with respect to such Loans or within such earlier period as required by law. If
any such conversion of a Eurodollar Loan occurs on a day which is not the last
day of the then current Interest Period with respect thereto, the Borrower shall
pay to such Bank such amounts, if any, as may be required pursuant to Section
2.15.

               2.13 Requirements of Law. (a) In the event that any change in any
                    -------------------
Requirement of Law or in the interpretation, or application thereof or
compliance by any Bank with any request or directive (whether or not having the
force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

                         (i)   shall subject any Bank to any tax of any kind
         whatsoever with respect to this Agreement, any Note, any Letter of
         Credit, any Application or any Eurodollar Loan made by it, or change
         the basis of taxation of payments to such Bank in respect thereof
         (except for taxes covered by Section 2.14 and changes in the rate of
         tax on the overall net income, gross receipts or revenue of such Bank);

                         (ii)  shall impose, modify or hold applicable any
         reserve, special deposit or similar requirement against assets held by,
         deposits or other liabilities in or for the account of, advances, loans
         or other extensions of credit by, or any other acquisition of funds by,
         any office of such Bank which is not otherwise included in the
         determination of the interest rate on such Eurodollar Loan hereunder;
         or

                         (iii) shall impose on such Bank any other condition;
and the result of any of the foregoing is to increase the cost to such Bank, by
an amount which such Bank deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit or to reduce any amount receivable hereunder in respect
thereof then, in any such case, the Borrower shall as promptly as practicable
pay such Bank, upon its demand, any additional amounts necessary to compensate
such Bank for such increased cost or reduced amount receivable; provided, that
                                                                --------
the Borrower shall not be liable for any such amounts incurred by such Bank more
than 90 days prior to the date of such Bank's notification to the Borrower. If
any Bank becomes entitled to claim any additional amounts pursuant to this
subsection, it shall as promptly as practicable notify the Borrower, through the
Agent, of the event by reason of which it has become so entitled. A certificate
as to any additional amounts payable pursuant to this subsection submitted by
such Bank, through the Agent, to the Borrower shall be reasonably detailed and
include supporting documentation, and shall be conclusive in the absence of
manifest error. This covenant shall survive the termination of this Agreement
and the payment of the Notes and all other amounts payable hereunder.

                                       28
<PAGE>

                    (b)  In the event that any Bank shall have determined that
any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Bank or any
corporation controlling such Bank with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof does or shall have the effect of
reducing the rate of return on such Bank's or such corporation's capital as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Bank or such corporation could have achieved but for
such change or compliance (taking into consideration such Bank's or such
corporation's policies with respect to capital adequacy) by an amount deemed by
such Bank to be material, then from time to time, after submission by such Bank
to the Borrower (with a copy to the Agent) of a written request therefor, which
shall be reasonably detailed and include supporting documentation, the Borrower
shall pay to such Bank such additional amount or amounts as will compensate such
Bank for such reduction; provided, that the Borrower shall not be liable for any
such amounts incurred by such Bank more than 90 days prior to the date of such
Bank's notification to the Borrower.

                    (c)  Each Bank agrees that it will use reasonable efforts in
order to avoid or to minimize, as the case may be, the payment by the Borrower
of any additional amount under Section 2.13(b); provided, however, that no Bank
                                                --------  -------
shall be obligated to incur any expense, cost or other amount in connection with
utilizing such reasonable efforts.

                    (d)  Notwithstanding the foregoing Section 2.13(a), (b) and
(c), the Borrower shall not be required to pay any additional amounts to any
Bank that is not incorporated under the laws of the United States or a state
thereof as a result of any change in any Requirement of Law or compliance by
such Bank with any request or directive from any central bank or Governmental
Authority to the extent that such additional amounts exceed the amounts that
would have been payable by the Borrower under Section 2.13(a), (b) or (c) to a
Bank incorporated under the laws of the United States or a state thereof.

               2.14 Taxes. (a) All payments made by the Borrower under this
                    -----
Agreement and the Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority (excluding, net income taxes and franchise or gross
receipts taxes imposed in lieu of net income taxes imposed on the Agent or any
Bank as a result of a present or former connection between the jurisdiction of
the government or taxing authority imposing such tax and the Agent or such Bank
(excluding a connection arising solely from the Agent or such Bank having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement or the Notes)) (all such non-excluded taxes, levies,
imposts, duties, charges, fees, deductions and withholdings being hereinafter
called "Taxes"). If any Taxes are required to be withheld from any amounts
        -----
payable to the Agent or any Bank hereunder or under the Notes, the amounts so
payable to the Agent or such Bank shall be increased to the extent necessary to
yield to the Agent or such Bank (after payment of all Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement and the Notes. Whenever any Taxes are payable by the Borrower, as
promptly

                                       29
<PAGE>

as possible thereafter the Borrower shall send to the Agent for its own account
or for the account of such Bank, as the case may be, a certified copy of an
original official receipt received by the Borrower showing payment thereof. If
the Borrower fails to pay any Taxes when due to the appropriate taxing authority
or fails to remit to the Agent the required receipts or other required
documentary evidence, the Borrower shall indemnify the Agent and the Banks for
any incremental taxes, interest or penalties that may become payable by the
Agent or any Bank as a result of any such failure. The agreements in this
subsection shall survive the termination of this Agreement and the payment of
the Notes and all other amounts payable hereunder.

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

                    (c)  Notwithstanding the foregoing Section 2.14(a) or (b),
the Borrower shall not be required to pay any additional amounts pursuant to
such Sections (i) to any Bank in respect of United States withholding tax if (A)
the obligation to pay such additional amounts would not have arisen but for a
failure by such Bank to comply with the requirements of Section 2.14(b) or (B)
such Bank shall not have furnished the Borrower with such forms listed in
Section 2.14(b) and shall not have taken such other steps as reasonably may be
available to it under applicable tax laws and any applicable tax treaty or
convention to obtain an exemption from, or reduction (to the lowest applicable
rate) of, such United States withholding tax or (ii) to any Bank that is not
incorporated under the laws of the United States or a state thereof to the
extent that such additional amounts exceed the amounts that would have been
payable by the Borrower under Section 2.14(a) or (b) to a Bank incorporated
under the laws of the United States or a state thereof.

               2.15 Indemnity. (a) The Borrower agrees to indemnify each Bank
                    ---------
and to hold each Bank harmless from any loss or expense which such Bank may
sustain or incur as a consequence of (i) default by the Borrower in payment when
due of the principal amount of or interest on any Eurodollar Loan, (ii) default
by the Borrower in making a borrowing of,

                                       30
<PAGE>

conversion into or continuation of Eurodollar Loans after the Borrower has given
a notice requesting the same in accordance with the provisions of this
Agreement, (iii) default by the Borrower in making any prepayment after the
Borrower has given a notice thereof in accordance with the provisions of this
Agreement or (iv) the making of a prepayment of Eurodollar Loans on a day which
is not the last day of an Interest Period with respect thereto, except any such
loss as may result from the partial prepayment of Eurodollar Loans pursuant to
Section 4.1(k). This covenant shall survive the termination of this Agreement
and the payment of the Notes and all other amounts payable hereunder.

               (b) For the purpose of calculation of all amounts payable to a
Bank under this subsection, each Bank shall be deemed to have actually funded
its relevant Eurodollar Loan through the purchase of a deposit bearing interest
at the Eurodollar Rate in an amount equal to the amount of that Eurodollar Loan
and having a maturity comparable to the relevant Interest Period; provided,
                                                                  --------
however, that each Bank may fund each of its Eurodollar Loans in any manner it
-------
sees fit, and the foregoing assumption shall be utilized only for the
calculation of amounts payable under this subsection. This covenant shall
survive the termination of this Agreement and the payment of the Notes and all
other amounts payable hereunder.

          2.16 Pro Rata Treatment, etc. Except as required under Section 2.12,
               -----------------------
each Revolving Credit Borrowing, each payment or prepayment of principal of any
Revolving Credit Borrowing, each payment of interest on the Revolving Credit
Loans, each payment of Letter of Credit fees (other than fees for the account of
the Issuing Bank), each reduction of the Commitments, each refinancing of any
Borrowing with a Revolving Credit Borrowing of any Type, each payment of
Commitment Fees and each conversion of Revolving Credit Loans, shall be made pro
                                                                             ---
rata among the Banks in accordance with their respective Commitment Percentages.
----
Each Bank agrees that in computing such Bank's portion of any Borrowing to be
made hereunder, the Agent may, in its discretion, round each Bank's percentage
of such Borrowing to the next higher or lower whole dollar amount.

          2.17 Payments. (a) The Borrower shall make each payment (including
               --------
principal of or interest on any Loan or any fees or other amounts) hereunder not
later than 12:00 (noon), Wilmington time, on the date when due in Dollars to the
Agent at its offices specified in Section 9.2 or at such other place as may be
designated by the Agent, in immediately available funds. The Agent shall
distribute to the Banks any payments received by the Agent on the date received
in like funds as received.

               (b) Whenever any payment (including principal of or interest on
any Loan or any fees or other amounts) hereunder shall become due, or otherwise
would occur, on a day that is not a Business Day, such payment may be made on
the next succeeding Business Day, and such extension of time shall in such case
be included in the computation of interest or fees, if applicable.

          2.18 Conversion and Continuation Options. The Borrower shall have the
               -----------------------------------
right at any time upon prior irrevocable notice to the Agent (i) not later than
12:00 noon, Wilmington time, on the Business Day of conversion, to convert any
Eurodollar Loan to a Base Rate Loan,

                                       31
<PAGE>

(ii) not later than 12:00 noon, Wilmington time, three Business Days prior to
conversion or continuation, to (y) convert any Base Rate Loan into a Eurodollar
Loan, or (z) to continue any Eurodollar Loan as a Eurodollar Loan for any
additional Interest Period and (iii) not later than 12:00 noon, Wilmington time,
three Business Days prior to conversion, to convert the Interest Period with
respect to any Eurodollar Loan to another permissible Interest Period, subject
in each case to the following:

               (a) a Eurodollar Loan may not be converted at a time other than
the last day of the Interest Period applicable thereto;

               (b) any portion of a Loan maturing or required to be repaid in
less than one month may not be converted into or continued as a Eurodollar Loan;

               (c) no Eurodollar Loan may be continued as such and no Base Rate
Loan may be converted to a Eurodollar Loan when any Default or Event of Default
has occurred and is continuing and the Agent or the Required Banks have
determined that such a continuation is not appropriate;

               (d) any portion of a Eurodollar Loan that cannot be converted
into or continued as a Eurodollar Loan by reason of Section 2.18(b) or (c)
automatically shall be converted at the end of the Interest Period in effect for
such Loan to a Base Rate Loan; and

               (e) on the last day of any Interest Period for Eurodollar Loans
if the Borrower shall have failed to give notice of conversion or continuation
as described in this subsection or if such conversion or continuation is not
permitted pursuant to this Section 2.18, such Loans shall be converted to Base
Rate Loans on the last day of such then expiring Interest Period.

Accrued interest on a Loan (or portion thereof) being converted shall be paid by
the Borrower at the time of conversion.

          2.19 Use of Proceeds. The Letters of Credit and the proceeds of the
               ---------------
Loans shall be used by the Borrower for working capital and general corporate
purposes in the ordinary course of business.

                   SECTION 3. REPRESENTATIONS AND WARRANTIES

          To induce the Agent and the Banks to enter into this Agreement, and to
make the Loans and to issue and/or participate in Letters of Credit, the
Borrower hereby represents and warrants to the Agent and each Bank that:

          3.1  Financial Condition. (a) Audited Financials. The consolidated
               -------------------      ------------------
balance sheet of the Borrower and its consolidated Subsidiaries as at December
31, 2000 and the related consolidated statements of income and of cash flows for
the fiscal year ended on such date,

                                       32
<PAGE>

copies of which have heretofore been furnished to each Bank, present fairly the
consolidated financial condition of the Borrower and its consolidated
Subsidiaries as at such date, and the consolidated results of their operations
and their consolidated cash flows for the fiscal year then ended. All such
financial statements, including the related schedules and notes thereto, have
been prepared in accordance with GAAP applied consistently throughout the
periods involved. Neither the Borrower nor any of its consolidated Subsidiaries
had, as of December 31, 2000, any material Contingent Obligation, liability for
taxes, or any long-term lease or unusual forward or long-term commitment,
including, without limitation, any Interest Hedge Agreement, which is not
reflected in the financial statements contained in the Borrower's Annual Report
on Form 10-K for the period ended December 31, 2000 or the notes thereto.

               (b) No Sales. During the period from December 31, 2000, to and
                   --------
including the date of this Agreement there has been no sale, transfer or other
disposition by the Borrower or any of its consolidated Subsidiaries of any
material part of its business or property and no purchase or other acquisition
of any business or property (including any Capital Stock of any other Person)
material in relation to the financial condition of the Borrower and its
consolidated Subsidiaries at December 31, 2000.

          3.2 No Adverse Change. Since December 31, 2000, there has been no
              -----------------
development or event nor any prospective development or event which has had or

               -----
deficiency" (within the meaning of Section 412 of the Code or Section 302 of

representation is made or deemed made with respect to any Single Employer Plan,
and each Single Employer Plan has compiled in all material respects with the
applicable provisions of ERISA and the Code. No termination of a Single Employer
Plan has occurred and no lien in favor of the PBGC or a Plan has arisen during
the five-year period prior to the date as of which this representation is made
or deemed made. No other event or condition has occurred or exists with respect

               (b) The present value of all accrued benefits under each Single
Employer Plan in which the Borrower or any Commonly Controlled Entity is a
participant (based on those assumptions used to fund the Plans) did not, as of

made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits by an amount in excess of ten percent (10%) of
Consolidated Net Worth as of the end of the most recent fiscal year of the
Borrower for which financial statements have been delivered to the Banks
pursuant to this Agreement.

               (c) Neither the Borrower nor any Commonly Controlled Entity has
had a complete or partial withdrawal from any Multiemployer Plan, and neither
the Borrower nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made, in any such case which could reasonably be expected individually or
in the aggregate to have a Material Adverse Effect.

               (d) To the Borrower's knowledge, no such Multiemployer Plan is in
"reorganization" or "insolvent," within the meaning of such terms as used in
ERISA.

               (e) The present value (determined using actuarial and other
assumptions which are reasonable in respect of the benefits provided and the
employees participating) of the liability of the Borrower and each Commonly
Controlled Entity for post retirement benefits to be provided to their current
and former employees under Plans which are welfare benefit plans (as defined in
Section 3(1) of ERISA) does not, in the aggregate, exceed the assets under all
such Plans allocable to such benefits by an amount in excess of ten percent
(10%) of the Borrower's consolidated net worth as of the end of the most recent
fiscal year of the Borrower for which financial statements have been delivered
to the Banks pursuant to this Agreement.

               (a) The Properties do not contain, and have not previously
contained, in, on, or under, including, without limitation, the soil and
groundwater thereunder, any Materials of Environmental Concern in concentrations

material compliance with all Environmental Laws.

               (e) There are no governmental, administrative actions or judicial

consent decrees or other decrees, consent orders, administrative orders or other
orders, or other administrative or judicial requirements outstanding under any
Environmental Law with respect to any of the Properties.

documents and instruments as the Agent may request to evidence the creation and
perfection of the within security interest in such cash collateral account.

          Except as expressly provided above in this Section, presentment,
demand, protest and all other notices of any kind are hereby expressly waived.

                             SECTION 8. THE AGENT

          8.1  Appointment. Each Bank hereby irrevocably designates and appoints
               -----------
PNC Bank, Delaware as the Agent of such Bank under this Agreement. Each such
Bank irrevocably authorizes the Agent, as the agent for such Bank to take such
action on its behalf under the provisions of this Agreement and to exercise such
powers and perform such duties as are expressly delegated to the Agent by the
terms of this Agreement, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement, the Agent shall not have any duties or responsibilities, except
those expressly set forth herein, or any fiduciary relationship with any Bank,
and no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or otherwise exist against the
Agent. The Agent agrees to act as the Agent on behalf of the Banks to the extent
provided in this Agreement.

          8.2  Delegation of Duties. The Agent may execute any of its duties
               --------------------
under this Agreement by or through agents or attorneys-in-fact and shall be
entitled to engage and pay for the advice and services of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible to the
Banks for the negligence or misconduct of any agents or attorneys in-fact
selected by it with reasonable care.

          8.3  Exculpatory Provisions. Neither the Agent nor any of its
               ----------------------
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(a) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or the other Loan Documents
(except for its or such Person's own gross negligence or willful misconduct) or
(b) responsible in any manner to any of the Banks for any recitals, statements,
representations or warranties made by the Borrower or any officer thereof
contained in this Agreement, any other Loan Document or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Agent under or in connection with, this Agreement or the other Loan
Documents or for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement, the Notes or the other Loan Documents or for
any failure of the Borrower to perform its obligations hereunder or thereunder.
The Agent shall not be under any obligation to any Bank to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, this Agreement or the other Loan Documents, or to inspect
the properties, books or records of the Borrower or any Subsidiary.

          8.4  Reliance by Agent. The Agent shall be entitled to rely, and shall
               -----------------
be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit,

                                       51
<PAGE>

letter, cablegram, telegram, telecopy, telex or teletype message, statement,
order or other document or conversation believed by it to be genuine and correct
and to have been signed, sent or made by the proper Person or Persons and upon
advice and statements of legal counsel (including, without limitation, counsel
to the Borrower or any Subsidiary), independent accountants and other experts
selected by the Agent. The agent may deem and treat the payee of any Note as the
owner thereof for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with the Agent. The Agent
shall be fully justified in failing or refusing to take any action under this
Agreement unless it shall first receive such advice or concurrence of the
Required Banks as they deem appropriate or they shall first be indemnified to
its satisfaction by the Banks against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.
The Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement, the Notes and the other Loan Documents in
accordance with a request of the Required Banks, and such request and any action
taken or failure to act pursuant thereto shall be binding upon all the Banks and
all future holders of the Notes.

          8.5  Notice of Default. The Agent shall not be deemed to have
               -----------------
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless it has received notice from a Bank or the Borrower referring to
this Agreement, describing such Default or Event of Default and stating that
such notice is a "notice of default". In the event that the Agent receives such
a notice, the Agent shall give notice thereof to the Banks. The Agent shall take
such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required Banks; provided, that unless and until the
                                           --------
Agent shall have received such directions, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable in the best
interests of the Banks.

          8.6  Non-Reliance on Agent and Other Banks. Each Bank expressly
               -------------------------------------
acknowledges that neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representations
or warranties to it and that no act by the Agent hereinafter taken, including
any review of the affairs of the Borrower, shall be deemed to constitute any
representation or warranty by the Agent to any Bank. Each Bank represents to the
Agent that it has, independently and without reliance upon the Agent or any
other Bank, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Borrower and made its own decision to make its Loans hereunder and enter into
this Agreement. Each Bank also represents that it will, independently and
without reliance upon the Agent or any other Bank, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrower. Except for notices, reports and other documents expressly required to
be furnished to the Banks by the Agent hereunder, the Agent shall not have any
duty or responsibility to provide any Bank with any credit or other information
concerning the business, operations, property, condition (financial or

                                       52
<PAGE>

otherwise), prospects or creditworthiness of the Borrower or its Subsidiaries
which may come into the possession of the Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates.

          8.7  Indemnification. The Banks agree to indemnify the Agent in its
               ---------------
capacity as such (to the extent not reimbursed by the Borrower and without
limiting the obligation of the Borrower to do so), ratably according to their
respective Commitment Percentages, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the Notes)
be imposed on, incurred by or asserted against the Agent in any way relating to
or arising out of this Agreement, the other Loan Documents, or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agent under
or in connection with any of the foregoing; provided, that no Bank shall be
                                            --------
liable for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting solely from the Agent's gross negligence or willful misconduct. The
agreements in this Section 8.7 shall survive the payment of the Notes and all
other amounts payable hereunder.

          8.8  Agent in its Individual Capacity. The Agent and its Affiliates
               --------------------------------
may make loans to, accept deposits from and generally engage in any kind of
business with the Borrower as though it was not the Agent hereunder. With
respect to its Loans made or renewed by it and any Note issued to it and with
respect to any Letter of Credit issued or participated in it by it, the Agent
shall have the same rights and powers under this Agreement as any Bank and may
exercise the same as though it were not the Agent, and the terms "Bank" and
"Banks" shall include the Agent in its individual capacity.

          8.9  Successor Agent. The Agent may resign as Agent upon 30 days'
               ---------------
notice to the Banks and the Borrower. If the Agent shall resign as Agent under
this Agreement, then the Required Banks shall appoint from among the Banks a
successor agent for the Banks, which appointment shall be subject to the
approval of the Borrower (which approval shall not be unreasonably withheld) and
of such successor agent. Any rejection by the Borrower of a successor agent
shall specify the reasons for such rejection. Failure of the Borrower to approve
or reject a successor agent within ten days following request for approval shall
be deemed to constitute approval. Upon such appointment and approval, such
successor agent shall succeed to the rights, powers and duties of the Agent, and
the term "Agent" shall mean such successor agent effective upon its appointment,
and the former Agent's rights, powers and duties as Agent shall be terminated,
without any other or further act or deed on the part of such former Agent or any
of the parties to this Agreement or any holders of the Notes. After any retiring
Agent's resignation as Agent, the provisions of this Section 8 shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement.

          8.10 Beneficiaries. Except as expressly provided herein, the
               -------------
provisions of this Section 8 are solely for the benefit of the Agent and the
Banks, and the Borrower shall not have any rights to rely on or enforce any of
the provisions hereof. In performing its functions and

                                       53
<PAGE>

duties under this Agreement, the Agent shall act solely as agent of the Banks
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. MISCELLANEOUS

          9.1  Amendments and Waivers. Neither this Agreement, any Note or any
               ----------------------
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
subsection. With the written consent of the Required Banks, the Agent and the
Borrower may, from time to time, enter into written amendments, supplements or
modifications hereto and to the Notes and the other Loan Documents for the
purpose of adding any provisions to this Agreement or the Notes or the other
Loan Documents or changing in any manner the rights of the Banks or of the
Borrower hereunder or thereunder or waiving, on such terms and conditions as the
Agent may specify in such instrument, any of the requirements of this Agreement
or the Notes or the other Loan Documents or any Default or Event of Default and
its consequences; provided, however, that no such waiver and no such amendment,
                  --------  -------
supplement or modification shall directly or indirectly (a) reduce the amount or
extend the maturity of any Note or any installment thereof, or reduce the rate
or extend the time of payment of interest thereon, or reduce any fee payable to
any Bank hereunder, or change the duration or amount of any Bank's Commitment,
in each case without the consent of the Bank affected thereby or (b) amend,
modify or waive any provision of this Section 9.1 or reduce the percentages
specified in the definition of Required Banks or consent to the assignment or
transfer by the Borrower of any of its rights and obligations under this
Agreement, the Notes and the other Loan Documents, in each case without the
written consent of all the Banks, or (c) amend, modify or waive any provision of
Section 8 without the written consent of the then Agent, (d) amend, modify or
waive any provision of Section 2.3 without the written consent of the then Swing
Line Bank or (e) amend, modify or waive any provision of this Agreement relating
to any outstanding Letter of Credit without the written consent of the Issuing
Bank. Any such waiver and any such amendment, supplement or modification shall
apply equally to each of the Banks and shall be binding upon the Borrower, the
Banks, the Agent and all future holders of the Notes. In the case of any waiver,
the Borrower, the Banks and the Agent shall be restored to their former position
and rights hereunder and under the outstanding Notes, and any Default or Event
of Default waived shall be deemed to be cured and not continuing; but no such
waiver shall extend to any subsequent or other Default or Event of Default, or
impair any right consequent thereon.

          9.6  Successors and Assigns. (a) Except as otherwise provided in
               ----------------------
Section 9.8(b), whenever in this Agreement any of the parties hereto is referred
to, such reference shall be deemed to include the successors and assigns of such
party, and all covenants, promises and agreements by or on behalf of the
Borrower, the Agent or the Banks that are contained in this Agreement shall bind
and inure to the benefit of their respective successors and assigns. The
Borrower may not assign or transfer any of its rights or obligations under this
Agreement or the other Loan Documents without the prior written consent of each
Bank.

               (b)  Each Bank may, in accordance with applicable law, sell all
or a portion of its interests, rights and obligations under this Agreement and
the other Loan Documents (including all or a portion of its Commitment or, if an
Event of Default has occurred, the Swing Line Commitment, and the Loans at the
time owing to it and the Notes held by it); provided, however, that (i) each
                                            --------  -------
such assignment shall be to a Bank or Affiliate thereof, or, with the consents
of the Agent and the Borrower (which consents shall not be unreasonably
withheld) to one or more banks or other financial institutions, (ii) so long as
the Commitments are in effect, the amount of each such assignment (determined as
of the date the Assignment and Acceptance with respect to such assignment is
delivered to the Agent) shall not be less than $5,000,000 (or, if lower, the
lesser of (x) the full amount of such Bank's Commitments and (y) such amount as
the

                                       56
<PAGE>

Borrower and the Agent shall agree in their sole discretion), (iii) the parties
to each such assignment shall execute and deliver to the Agent an Assignment and
Acceptance, together with the Note or Notes subject to such assignment and a
processing and recordation fee of $2,000, (iv) in the case of the assignment of
the Swing Line Commitment, may only be made to a Bank which holds a Commitment
hereunder and must be of the entire Swing Line Commitment and (v) each such
assignment of Loans and all or any portion of a Bank's Commitment shall be of a
constant, and not a varying, percentage of the assigning Bank's Commitment and
Revolving Credit Loans then outstanding. Upon acceptance and recording pursuant
to paragraph (e) of this Section 9.6, from and after the effective date
specified in each Assignment and Acceptance, which effective date shall be at
least five Business Days after the execution thereof (unless otherwise agreed by
the Agent), (A) the assignee thereunder shall be a party hereto and, to the
extent of the interest assigned by such Assignment and Acceptance, have the
rights and obligations of a Bank under this Agreement and (B) the assigning Bank
thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all or the remaining portion of an
assigning Bank's rights and obligations under this Agreement and the other Loan
Documents, such Bank shall cease to be a party hereto but shall continue to be
entitled to the benefits of Sections 2.12, 2.13, 2.14, 2.15 and 9.5 (to the
extent that such Bank's entitlement to such benefits arose out of such Bank's
position as a Bank prior to the applicable assignment), as well as to any
Commitment Fees accrued for its account and not yet paid). Such Assignment and
Acceptance shall be deemed to amend this Agreement to the extent, and only to
the extent, necessary to reflect the addition of such assignee Bank and the
resulting amounts and percentages held by the Banks arising from the purchase by
such assignee Bank of all or a portion of the rights and obligations of such
assigning Bank under this Agreement, the Notes and the other Loan Documents.
Notwithstanding any provision of this Section 9.6, the consent of the Borrower
shall not be required for any assignment which occurs at any time when an Event
of Default shall have occurred and be continuing.

          (c)  By executing and delivering an Assignment and Acceptance, the
assigning Bank thereunder and the assignee thereunder shall be deemed to confirm
to and agree with each other and the other parties hereto as follows: (i) such
assigning Bank warrants that it is the legal and beneficial owner of the
interest being assigned thereby, free and clear of any adverse claim, and that
its Commitment and/or Commitments and/or Swing Line Commitment, as the case may
be, and the outstanding balances of its Loans, in each case without giving
effect to assignments thereof which have not become effective, are as set forth
in such Assignment and Acceptance, (ii) except as set forth in (i) above, such
assigning Bank makes no representation or warranty and assumes no responsibility
with respect to any statements, warranties or representations made in or in
connection with this Agreement or the other Loan Documents, or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this
Agreement or the other Loan Documents, or any other instrument or document
furnished pursuant hereto or thereto, or the financial condition of the Borrower
or any Subsidiary or the performance or observance by the Borrower or any
Subsidiary of any of their obligations under this Agreement or any other
instrument or document furnished pursuant hereto; (iii) such assignee represents
and warrants that it is legally authorized to enter into such Assignment and
Acceptance; (iv) such assignee confirms that it has received a copy of this
Agreement, together

                                       57
<PAGE>

with copies of the most recent financial statements delivered pursuant to
Section 5.1 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (v) such assignee will independently and without
reliance upon the Agent, such assigning Bank or any other Bank and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement and the other Loan Documents; (vi) such assignee appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement and the other Loan Documents as are delegated
to the Agent by the terms hereof, together with such powers as are reasonably
incidental thereto; and (vii) such assignee agrees that it will perform in
accordance with their terms all the obligations which by the terms of this
Agreement and the other Loan Documents are required to be performed by it as a
Bank.

          (d)  The Agent shall maintain at its offices a copy of each Assignment
and Acceptance and the names and addresses of the Banks, and the Commitment
and/or Swing Line Commitment of, and principal amount of the Loans owing to,
each Bank pursuant to the terms hereof from time to time (the "Register"). The
                                                               --------
entries in the Register shall be conclusive in the absence of manifest error and
the Borrower, the Agent and the Banks may treat each person whose name is
recorded in the Register pursuant to the terms hereof as a Bank hereunder for
all purposes of this Agreement. The Register shall be available for inspection
by the Borrower and any Bank, at any reasonable time and from time to time upon
reasonable prior notice.

          (e)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Bank and an assignee together with the Note or Notes
subject to such assignment, the processing and recordation fee referred to in
paragraph (b) above, the Agent shall (i) accept such Assignment and Acceptance,
(ii) record the information contained therein in the Register and (iii) give
prompt notice thereof to the Banks. Within five Business Days after receipt of
notice, the Borrower, at its own expense, shall execute and deliver to the
Agent, in exchange for the surrendered original Note(s), (x) a new Revolving
Credit Note to the order of such assignee in an amount equal to the portion of
the Commitment assumed by it pursuant to such Assignment and Acceptance and, if
applicable, a new Swing Line Note to the order of such assignee in an amount
equal to the Swing Line Commitment and, (y) if the assigning Bank has retained a
Commitment, a new Revolving Credit Note to the order of such assigning Bank in a
principal amount equal to the applicable Commitment retained by it. Such new

obligations, (iii) such Bank shall remain the holder of any such Note for all

which such Participant has an interest that forgives principal, interest or fees
or reduces the interest rate or fees payable with respect to any such Loan or
Commitment, or postpones any date fixed for any regularly scheduled payment of

transfer occurred.

               (h)  If any Participant of a Bank is organized under the laws of

withholding tax exemptions.

               (i)  Any Bank may at any time assign all or any portion of its
rights under this Agreement and the Notes issued to it to a Federal Reserve
Bank; provided that no such assignment shall release a Bank from any of its

obligations hereunder.

          9.7  Disclosure of Information. Unless otherwise consented to by the
               -------------------------
Borrower in writing, each of the Banks and the Agent agrees (on behalf of itself
and each of its affiliates, directors, officers, employees and representatives)
to use reasonable precautions to keep confidential, in accordance with its
customary procedures for handling confidential information of the same nature
and in accordance with safe and sound banking practices, any non-public
information supplied to it by the Borrower pursuant to this Agreement; provided,
                                                                       --------
that nothing herein shall limit the disclosure of any such information (a) to
the extent required by

                                       59
<PAGE>

statute, rule, regulation or judicial process, (b) to counsel for any Bank or
the Agent, (c) to bank examiners, auditors or accountants, (d) to the Agent or
any other Bank, (e) in connection with any litigation to which any one or more
of the Banks or the Agent is a party involving the Borrower or any Subsidiary or
its or their properties or in any way relating to this Agreement or any other
Loan Document or any Loans or Letters of Credit or other obligations of the
Borrower to the Agent or any Bank and (f) to any Participant or assignee Bank
(or prospective Participant or assignee Bank) so long as such Participant or
assignee Bank (or prospective Participant or assignee Bank) agrees to comply
with the requirements of this Section. In the event of any disclosure pursuant
to clauses (a) or (e) above, the Agent or Bank making such disclosure, as the
case may be, shall use its reasonable best efforts to notify the Borrower prior
to making such disclosure, and shall cooperate with the Borrower, at the
Borrower's expense, in obtaining a protective order if the Borrower so chooses.

          9.8  Adjustments; Set-off. (a) If any Bank (a "benefitted Bank") shall
               --------------------
at any time receive any payment of all or part of its Loans or the Reimbursement
Obligation owing to it, or interest thereon, or receive any collateral in
respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to
events or proceedings of the nature referred to in Section 7.1(g), or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Bank, if any, in respect of such other Bank's Loans or the
Reimbursement Obligation owing to it, or interest thereon, such benefitted Bank
shall purchase for cash from the other Banks such portion of each such other
Bank's Loans or the Reimbursement Obligation owing to it, or shall provide such
other Banks with the benefits of any such collateral, or the proceeds thereof,
as shall be necessary to cause such benefitted Bank to share the excess payment
or benefits of such collateral or proceeds ratably with each of the Banks;
provided, however, that if all or any portion of such excess payment or benefits
--------  -------
is thereafter recovered from such benefitted Bank, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest. The Borrower agrees that each Bank so purchasing
a portion of another Bank's Loans or Reimbursement Obligations may exercise all
rights of payment (including, without limitation, rights of set-off) with
respect to such portion as fully as if such Bank were the direct holder of such
portion.

               (b)  In addition to any rights and remedies, of the Banks
provided by law, upon the occurrence of an Event of Default, each of the Banks
shall have the right, without prior notice to the Borrower, any such notice
being expressly waived by the Borrower to the extent permitted by applicable
law, upon any amount becoming due and payable by the Borrower hereunder or under
the Notes (whether at the stated maturity, by acceleration or otherwise) to set-
off and appropriate and apply against such amount any and all deposits (general
or special, time or demand, provisional or final), in any currency, and any
other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Bank to or for the credit or the account of the Borrower.
Each of the Banks agrees promptly to notify the Borrower and the Agent after any
such set-off and application made by such Bank, provided, that the failure to
                                                --------
give such notice shall not affect the validity of such set-off and application.

accrued for its account and not yet paid). As provided in Section 9.6 of the
Credit Agreement and notwithstanding any other provision of this Assignment and
Acceptance Agreement, the consent of the Borrower shall not be required for any

other instrument or document furnished pursuant thereto, or the financial

documents and information as it shall deem appropriate at the time, make its own
credit decisions in taking or not taking action under the Credit Agreement and
the other Loan Documents, (iv) appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise such powers under the Credit

treaty, all duly completed and executed by such Assignee, and (iv) a processing
and recordation fee of $2,000.

          6. Upon acceptance and recording of this Assignment and Acceptance
Agreement in accordance with the Credit Agreement, the Agent shall, from and
after the Effective Date, make all payments in respect of the Assigned Interest
(including payments of principal, interest, fees and other amounts) (other than
on account of Commitment Fees accrued and not yet paid) to the Assignee whether

the Effective Date. The Assignor and the Assignee shall make all appropriate
adjustments in payments by the Agent for periods prior to the Effective Date or
with respect to the making of this assignment directly between themselves.

          7. This Assignment and Acceptance Agreement shall be governed by and

                                                              September __, 2001

PNC Bank, Delaware, as Agent for the
  banks and other financial institutions
  party to the Credit Agreement referred to below
3 The Plaza
Dover, Delaware 19901

Ladies and Gentlemen:

          We have acted as counsel to Dover Downs Entertainment, Inc., a
Delaware corporation (the "Borrower"), Dover Downs, Inc., a Delaware
corporation, Dover Downs International Speedway, Inc., a Delaware corporation,
Dover Downs Properties, Inc., a Delaware corporation, Gateway International
Motorsports Corporation, an Illinois corporation, Gateway International Services
Corporation, an Illinois corporation, Grand Prix Association of Long Beach,
Inc., a California corporation, Memphis International Motorsports Corporation, a
Tennessee corporation, Motorsports Services Corporation of Memphis, a Tennessee
corporation, and Nashville Speedway USA, Inc., a Tennessee corporation (each, a
"Guarantor" and collectively, the "Guarantors") in connection with the execution
and delivery of the Credit Agreement dated as of September 14, 2001 (the "Credit
Agreement"), among the Borrower, the banks and other financial institutions
party thereto and PNC Bank, Delaware, as agent, and the transactions
contemplated thereby. This opinion is delivered to you pursuant to Section
4.1(g) of the Credit Agreement. Terms defined in the Credit Agreement and not
otherwise defined herein shall have the meanings assigned to them in the Credit
Agreement.

          In so acting, we have examined executed originals or counterparts of
the following documents, each dated the date hereof (the "Loan Documents"):

          (a) the Credit Agreement;

          (b) the Notes; and

          (c) the Guaranty Agreement.

          We have also examined the articles or certificate of incorporation and
bylaws, each as amended to date, of the Borrower and each Guarantor and such
other documents and instruments and have made such further inquiries as we have
deemed appropriate for purposes of this opinion. As to certain issues of fact,
we have, where such facts were not independently known to us, relied with your
consent and without independent investigation upon the
<PAGE>

representations and warranties made by the Borrower in the Credit Agreement and
upon certificates of representatives of the Borrower dated September __, 2001.

          On the basis of the foregoing, we are of the opinion that:

          1.   The Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware and is duly
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction where the business conducted by it requires such
qualification.

          2.   The Borrower has the corporate or other power and authority to
own or lease and operate its properties and assets, to conduct the business in
which it is now engaged, and to execute and deliver and perform its obligations
under the Loan Documents to which it is a party. The execution, delivery and
performance of the Loan Documents to which it is a party by the Borrower have
been duly authorized by all necessary action on the part of the Borrower.

          3.   Each Guarantor is a corporation duly incorporated, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has the corporate power and authority to own or lease and
operate its properties and assets, to conduct the business in which it is now
engaged, and to execute the Guaranty Agreement.

          4.   The Loan Documents to which the Borrower is a party delivered on
the Closing Date have each been duly executed and delivered by or on behalf of
the Borrower and are valid and binding obligations of the Borrower enforceable
against the Borrower in accordance with their respective terms, except as the
same may be limited by bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance or other similar laws or equitable principles affecting
the enforcement of creditors' rights generally.

          5.   The Guaranty Agreement has been duly executed and delivered by or
on behalf of each Guarantor and is the valid and binding obligation of each
Guarantor enforceable against such Guarantor in accordance with its terms,
except as the same may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or other similar laws or equitable principles
affecting the enforcement of creditors' rights generally.

          6.   No authorization, approval or consent of, or filing or
registration with, any governmental or regulatory body of the United States of
America or the State of Delaware is required in connection with the execution,
delivery and performance by the Borrower or any Guarantor of the Loan Documents
to which it is a party or for any borrowings by the Borrower under the Credit
Agreement.

          7.   Neither the execution and delivery by the Borrower or any
Guarantor of the Loan Documents to which it is a party nor the performance and
observance by the Borrower or the Guarantors of their respective obligations
thereunder, will conflict with, or result in any violation or breach by the
Borrower or any Guarantor of or constitute a default under (or an event which,
with or without due notice or lapse of time or both, would constitute a default
under), or accelerate the performance required by, or result in the creation of
any Lien upon any

                                       2
<PAGE>

of the properties or assets of the Borrower or any Guarantor under any
of the terms, conditions or provisions of or require any filing or consent under
(i) the Borrower's or any Guarantor's articles or certificate of incorporation
or bylaws, (ii) any existing law, statute or governmental regulation applicable
to the Borrower or any Guarantor, or (iii) to our knowledge, any judgment,
order, decree, writ or injunction of any court, arbitrator or governmental
department, commission, agency or instrumentality or any indenture, contract,
guaranty or other agreement or instrument to which the Borrower or any Guarantor
is a party or by which it or its properties may be bound or affected.

          8.   To our knowledge, there is no action, suit, proceeding or
investigation at law or in equity, before any court, public board or body,
pending or threatened against or affecting the Borrower wherein an unfavorable
decision, ruling or finding would, individually or collectively, have a material
adverse effect on the business or financial condition of the Borrower.

          9.   The borrowing on the date hereof under the Credit Agreement and
the Notes and the application of the proceeds thereof as contemplated by the
Credit Agreement and the other Loan Documents do not violate any of the
provisions of Regulation U or X of the Board of Governors of the Federal Reserve
System.

(Hereinafter referred to as "Bank")

Borrower promises to pay to the order of Bank, in lawful money of the United
States of America, at its office indicated above or wherever else Bank may
specify, the sum of Three Million and No/100 Dollars ($3,000,000.00) or such sum
as may be advanced and outstanding from time to time, with interest on the
unpaid principal balance at the rate and on the terms provided in this
Promissory Note (including all renewals, extensions or modifications hereof,
this "Note").

RENEWAL/MODIFICATION. This Promissory Note renews, extends and/or modifies that
certain Promissory Note i/n/o PRWW, Ltd. dated October 6, 2000 (the "Original
Promissory Note"), evidencing an original principal amount of $3,000,000.00.
This Promissory Note is not a novation.

INTEREST RATE. Interest shall accrue on the unpaid principal balance of this
Note from the date hereof at the Bank's Prime Rate minus 0.35%, as that rate may
change from time to time in accordance with changes in the Bank's Prime Rate
("Interest Rate"). "Bank's Prime Rate" shall be that rate announced by Bank from
time to time as its prime rate and is one of several interest rate bases used by
Bank. Bank lends at rates both above and below Bank's Prime Rate, and Borrower
acknowledges that Bank's Prime Rate is not represented or intended to be the
lowest or most favorable rate of interest offered by Bank.

DEFAULT RATE. In addition to all other rights contained in this Note, if a
Default (as defined herein) occurs and as long as a Default continues, all
outstanding Obligations shall bear interest at the Interest Rate plus 3%
("Default Rate"). The Default Rate shall also apply from acceleration until the
Obligations or any judgment thereon is paid in full.

INTEREST AND FEE(S) COMPUTATION (ACTUAL/360). Interest and fees, if any, shall
be computed on the basis of a 360-day year for the actual number of days in the
applicable period ("Actual/360 Computation"). The Actual/360 Computation
determines the annual effective interest yield by taking the stated (nominal)
rate for a year's period and then dividing said rate by 360 to determine the
daily periodic rate to be applied for each day in the applicable period.
Application of the Actual/360 Computation produces an annualized effective rate
exceeding the nominal rate.

REPAYMENT TERMS. This Note shall be due and payable in consecutive monthly
payments of accrued interest only, commencing on October 1, 2001, and continuing

principal and accrued interest shall be due and payable on June 30, 2002.

APPLICATION OF PAYMENTS. Monies received by Bank from any source for application
toward payment of the Obligations shall be applied to accrued interest and then
to principal. If a Default occurs, monies may be applied to the Obligations in
any manner or order deemed appropriate by Bank.

If any payment received by Bank under this Note or other Loan Documents is
rescinded, avoided or for any reason returned by Bank because of any adverse
claim or threatened action, the returned payment shall remain payable as an
obligation of all persons liable under this Note or other Loan Documents as
though such payment had not been made.

other Loan Documents refers to all documents executed in connection with or
related to the loan evidenced by this Note and any prior notes which evidence
all or any portion of the loan evidenced by this Note, and any letters of credit

Commercial Code.

LATE CHARGE. If any payments are not timely made, Borrower shall also pay to
Bank a late charge equal to 5% of each payment past due for 10 or more days.

Acceptance by Bank of any late payment without an accompanying late charge shall
not be deemed a waiver of Bank's right to collect such late charge or to collect
a late charge for any subsequent late payment received.

ATTORNEYS' FEES AND OTHER COLLECTION COSTS. Borrower shall pay all of Bank's
reasonable expenses incurred to enforce or collect any of the Obligations
including, without limitation, reasonable arbitration, paralegals', attorneys'
and experts' fees and expenses, whether incurred without the commencement of a
suit, in any trial, arbitration, or administrative proceeding, or in any
appellate or bankruptcy proceeding.

this paragraph, exceed the maximum lawful rate, the effective interest rate
under this Note shall be the maximum lawful rate, and any amount received by

as defined in 11 U.S.C. ss. 101, except that the term "Borrower" shall be
substituted for the term "Debtor" therein; "Subsidiary" shall mean any business

Borrower, including capitalized leases and all reserves for deferred taxes and
other deferred sums appearing on the liabilities side of a balance sheet of
Borrower, in accordance with generally accepted accounting principles applied on
a consistent basis. "Tangible Net Worth" shall mean total assets minus total
liabilities. For purposes of this computation, the aggregate amount of any
intangible assets of Borrower including, without limitation, goodwill,

liabilities shall include debt fully subordinated to Bank on terms and

total principal balance outstanding under this Note at any one time does not
exceed the principal amount stated on the face of this Note, subject to the
limitations described in any loan agreement to which this Note is subject.
Bank's obligation to make Advances under this Note shall terminate if Borrower
is in Default. As of the date of each proposed Advance, Borrower shall be deemed
to represent that each representation made in the Loan Documents is true as of
such date. 30-Day Payout. During the term of the Note, Borrower agrees to pay
down the outstanding balance to a maximum of $100.00 for 30 consecutive days
annually.

If Borrower subscribes to Bank's cash management services and such services are
applicable to this line of credit, the terms of such service shall control the
manner in which funds are transferred between the applicable demand deposit
account and the line of credit for credit or debit to the line of credit.

WAIVERS AND AMENDMENTS. No waivers, amendments or modifications of this Note and
other Loan Documents shall be valid unless in writing and signed by an officer
of Bank. No waiver by Bank of any Default shall operate as a waiver of any other
Default or the same Default on a future occasion. Neither the failure nor any
delay on the part of Bank in exercising any right, power, or remedy under this
Note and other Loan Documents shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or remedy.

Each Borrower or any person liable under this Note waives presentment, protest,
notice of dishonor, demand for payment, notice of intention to accelerate
maturity, notice of acceleration of maturity, notice of sale and all other
notices of any kind. Further, each agrees that Bank may extend, modify or renew
this Note or make a novation of the loan evidenced by this Note for any period,
and grant any releases, compromises or indulgences with respect to any
collateral securing this Note, or with respect to any other Borrower or any
other person liable under this Note or other Loan Documents, all without notice
to or consent of each Borrower or each person who may be liable under this Note
or any other Loan Document and without affecting the liability of Borrower or
any person who may be liable under this Note or any other Loan Document.

shall inure to the benefit of and be binding upon the parties and their
respective heirs, legal representatives, successors and assigns. Bank's
interests in and rights under this Note and the other Loan Documents are freely
assignable, in whole or in part, by Bank. In addition, nothing in this Note or
any of the other Loan Documents shall prohibit Bank from pledging or assigning
this Note or any of the other Loan Documents or any interest therein to any
Federal Reserve Bank. Borrower shall not assign its rights and interest
hereunder without the prior written consent of Bank, and any attempt by Borrower
to assign without Bank's prior written consent is null and void. Any assignment
shall not release Borrower from the Obligations. Applicable Law; Conflict
Between Documents. This Note and, unless otherwise provided in any other Loan
Document, the other Loan Documents shall be governed by and construed under the
laws of the state named in Bank's address shown above without regard to that
state's conflict of laws principles. If the terms of this Note should conflict

days. The expedited procedures set forth in Rule 51 et seq. of the Arbitration
Rules shall be applicable to claims of less than $1,000,000.00. Arbitrators
shall be licensed attorneys selected from the Commercial Financial Dispute
Arbitration Panel of the AAA. The parties do not waive applicable Federal or

claim or controversy with regard to any party's entitlement to such remedies is

have a remedy of punitive or exemplary damages against other parties in any
Dispute and hereby waive any right or claim to punitive or exemplary damages
they have now or which may arise in the future in connection with any Dispute
whether the Dispute is resolved by arbitration or judicially.
