Bank agrees to make revolving credit loans (the "Revolving Credit Loans") to
the Borrower from time to time during the Revolving Credit Commitment Period in
an aggregate principal amount at any one time outstanding not to exceed the
Available Revolving Credit Commitment; provided that, no Revolving Credit Loan
shall be made if, after giving effect to the making of such Loan and the
simultaneous application of the proceeds thereof, the Borrower would not be in
compliance with any of the applicable financial ratios set forth in Section 6.1.
The Revolving Credit Commitment may be reduced or terminated from time to time
pursuant to Section 2.9. Within the foregoing limits, the Borrower may during
the Revolving Credit Commitment Period borrow, repay and reborrow under the
Revolving Credit Commitment, subject to and in accordance with the terms and
limitations hereof.

             (b) The Revolving Credit Loans may from time to time be
(i) Eurodollar Loans, (ii) Base Rate Loans or (iii) a combination thereof, as
determined by the Borrower and notified to the Bank in accordance with Sections
2.3 and 2.16; provided that, no Revolving Credit Loan shall be made as a

                                       18


             (d) Subject to the terms and conditions hereof, the Bank shall
during the Revolving Credit Commitment Period issue or cause the issuance of
letters of credit ("Revolving Credit Letters of Credit") on behalf of the
Borrower; provided, however, that the Bank will not be required to issue or
cause to be issued any Revolving Credit Letter of Credit which expires later
than the Revolving Credit Termination Date or to the extent that the face amount
of such Revolving Credit Letters of Credit would exceed the Available Revolving
Credit Commitment; provided further, that the Bank shall not be required to
issue any Revolving Credit Letter of Credit if, after giving effect to such
issuance, the Borrower would not be in compliance with any of the applicable
financial ratios set forth in Section 6.1. The maximum amount of outstanding
Revolving Credit Letters of Credit shall not exceed $7,500,000 at any time; the
maximum amount of outstanding Revolving Credit Letters of Credit which are
standby letters of credit shall not exceed $5,000,000 at any time; and the

letters of credit shall not exceed $2,500,000 at any time. The Borrower shall be

and shall bear interest at the applicable Base Rate until repaid in full.

such issuance ("Cash Collateralized Letters of Credit") on behalf of the
Borrower; provided, however, that the Bank will not be required to issue or
cause to be issued any Cash Collateralized Letter of Credit which expires later
than the Revolving Credit Termination Date or to the extent that, after giving
effect to such issuance, the face amount of all outstanding Cash Collateralized
Letter of Credit Obligations would exceed either (i) the Cash Collateralized
Letters of Credit Commitment or (ii) the amount then held by the Bank in the
Cash Collateral Account. The Borrower shall be required to reimburse the Bank
any amounts paid by the Bank pursuant to drawings on Cash Collateralized Letters
of Credit. If any such amount is not otherwise reimbursed by the Borrower on the
date of such drawing, the Bank may debit a like amount from the Cash Collateral
Account and apply it to such Reimbursement Obligation. The Borrower shall at all
times maintain deposits in the Cash Collateral Account in an amount equal to or
greater than the Cash Collateralized Letters of Credit Obligations. The Bank
will invest such cash collateral (less applicable reserves) in such short-term
money- market investments as to which the Bank and the Borrower mutually agree
and the net return on such investments shall be credited to such account and
constitute additional cash collateral. Following the occurrence of a Default or
Event of Default the Borrower may not withdraw amounts credited to the Cash
Collateral Account except upon payment and performance in full of all
Obligations, expiration or surrender of all Letters of Credit and the Bond
Letter of Credit and termination of this Agreement.

             (f) Subject to the terms and conditions hereof and of the
Reimbursement Agreement, the Bank shall issue the Bond Letter of Credit in an
amount not to exceed $5,025,410. The Borrower shall reimburse the Bank for any
amounts paid by the Bank pursuant to drawings on the Bond Letter of Credit as
provided in, and the Bond Letter of Credit shall otherwise be governed by and
subject to, the Reimbursement Agreement.

         2.2 Note The Revolving Credit Loans shall be evidenced by a promissory

and amount of each Revolving Credit Loan, each continuation thereof, each

each payment or prepayment of principal thereof and, in the case of Eurodollar

recordation) shall not affect the obligations of the Borrower hereunder or under
the Revolving Credit Note.

         2.3 Procedure for Revolving Credit Loans; Issuance of Letters of
Credit. (a) The Borrower may borrow under the Revolving Credit Commitment during
the Revolving Credit Commitment Period on any Business Day. The Borrower shall
give the Bank irrevocable notice (which notice must be received by the Bank
prior to 12:00 noon, Philadelphia time, three Business Days prior to the

Loans are to be initially Eurodollar Loans, or prior to 10:00 a.m., Philadelphia

Loans are to be initially Base Rate Loans), specifying in the Notice of
Borrowing (a) the amount to be borrowed, (b) the requested Borrowing Date, (c)
whether the borrowing is to be of Eurodollar Loans, Base Rate Loans or a
combination thereof and (d) if the borrowing is to be entirely or partly of
Eurodollar Loans, the amount and the length of the initial Interest Period(s)

aggregate Available Revolving Credit Commitment at such time is less than
$100,000, such lesser amount).

             (b) Borrower may request the Bank to issue or cause the issuance of
a Letter of Credit under either of the Commitments by delivering to the Bank, a
Letter of Credit Application (the "Application") in the form provided by the
Bank and completed to its reasonable satisfaction; and, such other certificates,
documents and other papers and information as the Bank may reasonably request.
Each Letter of Credit shall, among other things, (i) provide for the payment of
sight drafts when presented for honor thereunder in accordance with the terms
thereof and when accompanied by the documents described therein and (ii) have an
expiry date less than two years after such Letter of Credit's date of issuance
and in no event later than the Revolving Credit Termination Date (except that a
Letter of Credit may provide for automatic annual renewals in the absence of
notice from the Bank that it will not be renewed). Each Letter of Credit shall
be subject to the Uniform Customs and Practice for Documentary Credits, 1993
Revision, International Chamber of Commerce Publication No. 500 or International
Standby Practices, International Chamber of Commerce Publication No. 590, or
such other law as the Borrower and the Bank agree shall apply, and any
amendments or revision thereof adhered to by the Bank and, to the extent not
inconsistent therewith, the laws of the Commonwealth of Pennsylvania.

         2.4 Requirements for Issuance of Letters of Credit. (a) In connection

Letter of Credit to be issued or created for the Borrower. The Borrower shall be
bound by the Bank's reasonable regulations and good faith interpretations of any
Letter of Credit issued or created for the Borrower, although this
interpretation may be different from its own; and, neither the Bank nor any of
its correspondents shall be liable for any error, negligence, or mistakes,
whether of omission or commission, in following the Borrower's instructions or
those contained in any Letter of Credit or of any modifications, amendments or
supplements thereto or in issuing or paying any Letter of Credit, except for the
Bank's or any such correspondent's gross negligence, bad faith or willful

in the name of the Borrower for such purpose; and (iv) to complete in the
Borrower's name any order, sale or transaction, obtain the necessary documents
in connection therewith, and collect the proceeds thereof. This power, being
coupled with an interest, is irrevocable as long as any Letters of Credit remain
outstanding.

             (d) The Borrower and the Bank agree that the Bank shall not be
responsible for, and the Borrower's Reimbursement Obligations shall be absolute,
unconditional and irrevocable under all circumstances, and shall not be affected
by, among other things (1) the form, validity, enforceability, sufficiency,
accuracy, genuineness or legal effect of any Letter of Credit or any document
submitted by any party in connection with any Letter of Credit, even if it
should in fact prove to be in any or all respects invalid, insufficient,
inaccurate, fraud ulent or forged (even if the Bank shall have been notified
thereof), (2) the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign any such Letter of Credit or the
rights or benefits thereunder or proceeds thereof, in whole or in part, which
may prove to be invalid or ineffective for any reason, (3) any claim of the
Borrower against any beneficiary of such Letter of Credit, or any such
transferee, (4) any dispute between the Borrower and any beneficiary of any
Letter of Credit or any other party to which such Letter of Credit may be

failure to honor a presentation complying with the terms of such Letter of
Credit as a result of Governmental Acts or otherwise) by the Bank in connection
with a Letter of Credit, (11) any consequences arising from causes beyond the
control of the Bank, including any Governmental Acts, (12) the existence of any
claim, set-off, defense or other right which the Borrower may have at any time
against a beneficiary or any transferee of any Letter of Credit (or any Persons
for whom any such transferee may be acting), the Bank or any other Person or,
whether in connection with this Agreement, the transactions contemplated herein
or any unrelated transaction (including any underlying transaction between the
Borrower and the beneficiary for which any Letter of Credit was procured), (13)
any adverse change in the business, operations, properties, assets, condition
(financial or otherwise) or prospects of the Borrower, (14) any breach of this
Agreement or any other Loan Document by the Borrower, (15) the occurrence or
continuance of an insolvency proceeding with respect to the Borrower, (16) the
fact that the Revolving Credit Termination Date shall have passed or this
Agreement or either of the Commitments hereunder shall have been terminated, and
(17) any other circumstance or happening whatsoever, whether or not similar to
any of the foregoing, and none of the above shall affect or impair, or prevent
the vesting of, any of the Bank's rights or powers hereunder, provided, in each
case, that a court of competent jurisdiction has not finally determined that the
reliance by the Bank on any of such documents, instruments or acts, or any such
action by or omission of the Bank, constituted gross negligence or willful
misconduct of the Bank.

                                       21

presentation if the documents presented appear on their face substantially to

damages, or for any damages resulting from any change in the value of any
property relating to a Letter of Credit, (iv) may honor a previously dishonored

wrongful dishonor and shall be entitled to reimbursement to the same extent as

by the Bank, (v) may honor any drawing that is payable upon presentation of a
statement advising negotiation or payment, upon receipt of such statement (even

and (vi) may pay any paying or negotiating bank claiming that it rightfully
honored under the laws or practices of the place where such bank is located.

shall be conclusive and binding on the Borrower in the absence of manifest
error. At the request of the Borrower, the Bank shall deliver to the Borrower a
statement showing the quotations used by it in determining any interest rate
pursuant to subsections 2.6(a) and (b).

                                       23


         2.7 Default Interest. Upon the occurrence of and during the continuance
of an Event of Default, (i) the outstanding principal amount of all Obligations
other than Eurodollar Loans shall bear interest from the date of such occurrence
at a rate per annum which is equal to three percent (3%) in excess of the sum of
the Base Rate plus the Applicable Margin in effect at such time for Base Rate
Loans and (ii) Eurodollar Rate Loans shall bear interest at a rate per annum
which is equal to three percent (3%) in excess of the Eurodollar Rate plus the
Applicable Margin in effect at such time for Eurodollar Loans. The Borrower
acknowledges that such increased interest rate reflects, among other things, the
fact that such Loans, Letters of Credit or other amounts have become a
substantially greater risk given their default status and that the Bank is
entitled to additional compensation for such risk. Notwithstanding anything in
this Agreement to the contrary, upon the occurrence and during the continuance
of a Default or an Event of Default, all Eurodollar Loans shall be converted to
Base Rate Loans upon the expiration of any Interest Period.

         2.8 Inability to Determine Interest Rate. In the event, and on each
occasion, that prior to the first day of the commencement of any Interest Period
for a Eurodollar Loan, the Bank 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 Bank of
making or maintaining the principal amount of such Eurodollar Loan during such
Interest Period, or that reasonable means do not exist for ascertaining the
Eurodollar Rate, the Bank shall, as soon as practicable thereafter, give
written, telegraphic or telephonic notice of such determination to the Borrower.
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. Each
determination by the Bank hereunder shall be conclusive absent error in
calculation.

         2.9 Termination and Reduction of Commitments; Mandatory Prepayments.

             (a) Termination at Maturity. The Revolving Credit Commitment shall
be automatically terminated on the Revolving Credit Termination Date and the
Cash Collateralized Letters of Credit Commitment shall be automatically
terminated on the Cash Collateralized Letters of Credit Commitment Termination
Date. The entire outstanding principal balance of the Revolving Credit Loans and
all Reimbursement Obligations, plus all accrued and unpaid interest thereon, and
any Fees or other amounts owed under the Loan Documents, shall be due and
payable on the Revolving Credit Termination Date.

                                       24


             (b) Voluntary Reductions of Commitments. Upon at least five
Business Days' prior irrevocable written (including telecopy) notice to the
Bank, the Borrower may from time to time voluntarily permanently reduce or
terminate the Revolving Credit Commitment or the Cash Collateralized Letter of
Credit Commitment, provided, however, in the event the Commitments are
terminated in whole and the Obligations are prepaid in full prior to the last
day of the Revolving Credit Termination Date (the date of such prepayment
hereinafter referred to as the "Early Termination Date"), the Borrower shall pay
to the Bank an early termination fee in an amount equal to (x) 2% of the sum of
the aggregate amount of the Commitments and the Available Bond Letter of Credit
Amount in effect prior such termination if the Early Termination Date occurs on
or after the Closing Date to and including the date immediately preceding the
first anniversary of the Closing Date, and (y) 1% of the sum of the aggregate
amount of the Commitments and the Available Bond Letter of Credit Amount in
effect prior such termination if the Early Termination Date occurs on or after
the first anniversary of the Closing Date to and including the date immediately
preceding the second anniversary of the Closing Date. Each voluntary reduction
shall be in a minimum amount of $500,000 or in integral multiples of $100,000 in
excess thereof.

             (c) Effect of Reductions. The portion of the Commitments so
terminated pursuant to subsection 2.9(b) shall no longer be available for
borrowing or the issuance of Letters of Credit and, as of the effective date of
any such reduction, any Revolving Credit Commitment Fee shall no longer be
payable on the portion so terminated. Simultaneously with each voluntary
permanent reduction of the Revolving Credit Commitment, the Borrower shall make
a payment on the outstanding Revolving Credit Loans equal to the excess, if any,
of the aggregate principal amount of the outstanding Revolving Credit Loans and
the face amount of Revolving Credit Letters of Credit outstanding at such time
over the Revolving Credit Commitment, as so reduced. Notice of a reduction, once
given, shall be irrevocable. Except as otherwise provided in subsection 2.9(b),
all such reductions shall be without penalty or premium (except for amounts
owing pursuant to Section 2.14, if any).

             (d) Mandatory Prepayments. If at any time the aggregate principal
amount of the outstanding Revolving Credit Loans and the face amount of
Revolving Credit Letters of Credit outstanding at such time exceeds the lesser
of the Revolving Credit Commitment and the Borrowing Base at such time, the
Borrower shall make a payment on the outstanding Revolving Credit Loans equal to
the amount of such excess.

             (e) Application of Reductions and Prepayments. All prepayments made
pursuant to subsections 2.9(c) or (d) shall be applied to repay Base Rate Loans
or Eurodollar Loans, at the Borrower's option, provided that the Borrower shall
deliver written notice of such election prior to or simultaneously with such
prepayment. If no election is made by the Borrower, then all such voluntary
prepayments shall be applied by the Bank to first repay Base Rate Loans, and any
excess shall be applied to repay Eurodollar Loans, with payments applied to
Eurodollar Loans being applied in order of next maturing Interest Periods. All
such mandatory and voluntary prepayments shall be accompanied by all accrued and
unpaid interest thereon, all amounts due pursuant to subsection 2.9(b) or
Section 2.14, if any, and, in the case of a permanent reduction of the Revolving
Credit Commitment to zero, any accrued and unpaid Commitment Fees.

        2.10 Optional Prepayment of Loans. (a) The Borrower shall have the
right at any time and from time to time to prepay the Loans, in whole or in
part, without premium or penalty (but in any event subject to Section 2.14),
upon prior written, telecopy or telephonic notice to the Bank given, in the case
of Base Rate Loans, no later than 10:00 a.m., Philadelphia time, on the date of
any proposed prepayment, and, in the case of Eurodollar Loans, no later than
10:00 a.m., Philadelphia time, three Business Days before any such proposed
prepayment. In each case the notice shall specify the date and amount of each
such prepayment, whether the prepayment is of Base Rate Loans, Eurodollar Loans,
or a combination thereof, and, if a combination thereof, the amount allocable to
each; provided, however, that each such partial prepayment shall be in the
principal amount of at least $100,000 or in multiples of $100,000 in excess
thereof.

                                       25



             (b) Each notice of prepayment shall be irrevocable and shall commit
the Borrower to prepay the amount specified in such notice.

        2.11 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 the Bank to make or maintain Eurodollar Loans as
contemplated by this Agreement, (a) the commitment of the Bank hereunder to make
Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans
to Eurodollar Loans shall forthwith be cancelled and (b) the 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
scheduled last day of the then current Interest Period with respect thereto, the
Borrower shall pay to the Bank such amounts, if any, as may be required pursuant
to subsection 2.14. The Bank shall endeavor to provide notice to the Borrower of
such change in any Requirement of Law or interpretation or application when the
Bank becomes aware of such change.

        2.12 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 the 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 the Bank to any tax of any kind whatsoever
with respect to this Agreement, the Revolving Credit Note, any Eurodollar Loan
or any Letter of Credit, or change the basis of taxation of payments to the Bank
in respect thereof (except for taxes covered by subsection 2.13 and changes in
the rate of tax on the net income of the Bank);

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

                 (iii) shall impose on the Bank any other condition;

and the result of any of the foregoing is to increase the cost to the Bank, by
an amount which the Bank deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or maintaining the Commitments
hereunder or issuing or maintaining any Letter of Credit hereunder or to reduce
any amount receivable hereunder in respect thereof then, in any such case, the
Borrower shall as promptly as practicable pay the Bank, upon its demand, any
additional amounts necessary to compensate the Bank for such increased cost or
reduced amount receivable. If the Bank becomes entitled to claim any additional
amounts pursuant to this subsection, it shall as promptly as practicable notify
the Borrower 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 the Bank to the Borrower shall be conclusive in the absence of
manifest error. This covenant shall survive the termination of this Agreement
and the payment of the Revolving Credit Note and all other amounts payable
hereunder.

                                       26


             (b) In the event that the 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 the Bank or any
corporation controlling the 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 the Bank's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which the Bank or
such corporation could have achieved but for such change or compliance (taking
into consideration the Bank's or such corporation's policies with respect to
capital adequacy) by an amount deemed by the Bank to be material, then from time
to time, the Borrower shall pay the Bank, upon its demand, such additional
amount or amounts as will compensate the Bank for such reduction. If the Bank
becomes entitled to claim any additional amounts pursuant to this subsection, it
shall as promptly as practicable notify the Borrower of the event by reason of
which it has become so entitled. A certificate as to any additional amounts
payable pursuant to this subsection setting forth the calculation of such
amounts in reasonable detail submitted by the Bank to the Borrower shall be
conclusive in the absence of manifest error. This covenant shall survive the
termination of this Agreement and the payment of the Revolving Credit Note and
all other amounts payable hereunder.

             (c) The 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 subsections 2.12(a) or (b); provided, however, that the
Bank shall not be obligated to incur any expense, cost or other amount in
connection with utilizing such reasonable efforts.

        2.13 Taxes. (a) All payments made by the Borrower under this Agreement
and any Note 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 (i) net income taxes and franchise or gross
receipts taxes imposed on the Bank as a result of a present or former connection
between the jurisdiction of the government or taxing authority imposing such tax
and the Bank (excluding a connection arising solely from the Bank having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement or the Revolving Credit Note (ii) any taxes which would
not be imposed but for the failure of the Bank or a participant to provide
properly completed and executed documentation reasonably requested by the
Borrower, as would permit the Borrower to make payments without withholding or
at a reduced rate, provided that the foregoing shall not apply if the Bank or
participant is not legally able or entitled to deliver such documentation, and
(iii) with respect to any Foreign Lender that is an assignee pursuant to Section
8.6, any withholding tax that is in effect and would apply to amounts payable to
such Foreign Lender at the time such Foreign Lender becomes a party to this
Agreement except to the extent the assignor with respect to such Foreign Lender
would have been entitled at the time of assignment to receive additional amounts
from the Borrower with respect to such withholding tax pursuant to this Section
2.13 (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 Bank hereunder or under
any Note, the amounts so payable to the Bank shall be increased to the extent
necessary to yield to the 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 Revolving Credit Note. If the Borrower fails to pay any Taxes
when due to the appropriate taxing authority or fails to remit to the Bank the
required receipts or other required documentary evidence, the Borrower shall
indemnify the Bank for any incremental taxes, interest or penalties that may
become payable by the 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 Revolving Credit Note and all other amounts payable hereunder.

                                       27


             (b) In the event of an assignment pursuant to Section 8.6, any
Foreign Lender that is entitled to an exemption from or reduction of withholding
tax under the law of the jurisdiction in which the Borrower is located, or any
treaty to which such jurisdiction is a party, with respect to payments under
this Agreement shall deliver to the Borrower, at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by
applicable law or reasonably requested by the Borrower as will permit such
payment to be made without withholding or at a reduced rate. The Bank and
participant shall provide to the Borrower such properly completed and signed
United States federal income tax in the form of Internal Revenue Form W-9 (or
applicable successor form) in the case of a person that is a "United States
person" within the meaning of Section 7701(a)(3) of the Code or an Internal
Revenue Service Form W-8BEN, W-8ECI or W-8IMY (or applicable successor form) in
the case of a person that is not a "United States person" within the meaning of
Section 7701(a)(30) of the Code) as may be reasonably requested by the Borrower,
so that the Borrower may make payments of principal and interest on any Loan
without United States federal back- up withholding.

             (c) If the Bank determines, in its sole discretion, that it has
received a refund of other Taxes as to which it has been indemnified by the
Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this Section 2.13, it shall pay over such refund to the Borrower
(but only to the extent of indemnity payments made, or additional amounts paid
by the Borrower under this Section 2.13 with respect to the Taxes giving rise so
such refund), net of all out-of-pocket expenses of the Lender and without
interest (other than any interest paid by the relevant governmental authority
with respect to such refund); provided, that the Borrower, upon the request of
the Bank, agrees to repay the amount paid over to the Borrower (plus any
penalties, interest or other charges imposed by the relevant governmental
authority) to the Bank in the event the Lender is required to repay such refund
to such governmental authority. This Section shall not be construed to require
the Bank to make available its tax returns (or any other information relating to
its taxes which it deems confidential) to the Borrower or any other Person.

        2.14 Indemnity. (a) The Borrower agrees to indemnify the Bank and to
hold the Bank harmless from any loss or expense which the 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, 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 (whether
voluntary, mandatory, as a result of acceleration or otherwise) of Eurodollar
Loans on a day which is not the last day of an Interest Period with respect
thereto, including, without limitation, in each case, any such loss or expense
arising from the reemployment of funds obtained by it or from fees payable to
terminate the deposits from which such funds were obtained. A certificate as to
any amounts that the Bank is entitled to receive under this Section 2.14
submitted by the Bank to the Borrower shall be conclusive in the absence of
clearly demonstrable error and all such amounts shall be paid by the Borrower
promptly upon demand by the Bank. This covenant shall survive the termination of
this Agreement and the payment of the Revolving Credit Note and all other
amounts payable hereunder.

                                       28



             (b) For the purpose of calculation of all amounts payable to the
Bank under this Section, the 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 such relevant Eurodollar
Loan and having a maturity comparable to the relevant Interest Period; provided,
however, that the 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 Section. This covenant shall survive
the termination of this Agreement and the payment of the Revolving Credit Note
and all other amounts payable hereunder.

        2.15 Payments. (a) The Borrower shall make each payment (including
principal of or interest on any borrowing or any fees or other amounts)
hereunder not later than 12:00 (noon), Philadelphia time, on the date when due
in Dollars to the Bank at its office set forth in Section 8.2, in immediately
available funds. Such payments shall be made without set off or counterclaim of
any kind.

             (b) Whenever any payment (including principal of or interest on any
borrowing or any Fees or other amounts) hereunder (other than payments on
Eurodollar Loans) 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.

             (c) In the event that any payment of principal, interest, Fees,
expenses or other amounts due to the Bank under any of the Loan Documents is not
paid when due, the Bank is hereby authorized to effect such payment by debiting
any demand deposit account of the Borrower now or in the future maintained with
the Bank. This right of debiting accounts of the Borrower is in addition to any
right of setoff accorded the Bank hereunder or by operation of law.

                                       29


        2.16 Conversion and Continuation Options. The Borrower shall have the
right at any time upon prior irrevocable notice to the Bank (i) not later than
12:00 noon, Philadelphia time, three Business Days prior to conversion, to
convert any Eurodollar Loan to a Base Rate Loan, (ii) not later than 12:00 noon,
Philadelphia time, three Business Days prior to conversion or continuation, to
convert any Base Rate Loan into a Eurodollar Loan or to continue any Eurodollar
Loan as a Eurodollar Loan for any additional Interest Period and (iii) not later
than 12:00 noon, Philadelphia 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 has occurred and is
continuing;

             (d) any portion of a Eurodollar Loan that cannot be converted into
or continued as a Eurodollar Loan by reason of subsections 2.16(b) or 2.16(c)
automatically shall be converted at the end of the Interest Period in effect for
such Loan to a Base Rate Loan; and

             (e) if the Borrower has failed to give notice of conversion or
continuation within the time periods set forth in this subsection or if such
conversion or continuation is not permitted pursuant to this Section 2.16, such
Loans shall be converted to Base Rate Loans on the last day of such then
expiring Interest Period.

Each request by the Borrower to convert or continue a Loan shall constitute a
representation and warranty that no Default shall have occurred and be
continuing. Accrued interest on a Loan (or portion thereof) being converted
shall be paid by the Borrower at the time of conversion.

        2.17 Minimum Amounts of Tranches; Maximum Number of Tranches. (a) All
borrowings, conversions and continuations of 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, the aggregate principal amount
of the Loans comprising each Tranche of Eurodollar Loans shall be equal to
$500,000 or in increments of $100,000 in excess thereof.

             (b) The Borrower shall not have outstanding at any one time more
than four Tranches in the aggregate including the Base Rate Tranche (to the
extent any Base Rate Loans are then outstanding).

        2.18 Loan Account. The Bank shall open and maintain on its books a loan
account (the "Loan Account") in the Borrower's name with respect to loans made,
Letters of Credit issued and drawings thereunder, repayments, prepayments, the
computation and payment of interest, Fees and other amounts due and sums paid to
the Bank hereunder and under the Loan Documents. Except in the case of manifest
error in computation, such records and any information recorded by the Bank on
the Revolving Credit Note shall constitute prima facie evidence of the accuracy
of the information so recorded; provided that, the failure of the Bank to make
an entry in the Loan Account or on the Revolving Credit Note (or any error in
such recordation) shall not affect the obligations of the Borrower hereunder or
under the Revolving Credit Note.

                                       30


        2.19 Use of Proceeds. The proceeds of the Loans shall be used by the
Borrower (a) for the Borrower's ongoing capital expenditures, working capital
and general purposes in the ordinary course of business, (b) to repay all
outstanding Indebtedness under the Existing Financing Agreements and (c) to pay
transaction costs in connection with the Loan Documents. The Borrower may not
transfer the proceeds of any Loans to, or otherwise directly or indirectly use
such funds or the proceeds thereof for the benefit of, any Subsidiary which is
not a Guarantor other than the payment of invoices in the ordinary course of
business for services rendered or goods sold by such Subsidiary.

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

         To induce the Bank to enter into this Agreement and to make the Loans
and to issue Letters of Credit, the Borrower hereby represents and warrants to
the Bank that:

         3.1 Financial Condition. (a) Audited Financials. The consolidated
balance sheet of the Borrower and its consolidated Subsidiaries as at
February 22, 2002 and the related consolidated statements of income and of cash
flows for the fiscal year ended on such date, 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
February 22, 2002, 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
foregoing statements or the notes thereto.

             (b) Unaudited Financials. The unaudited consolidated balance sheet
of the Borrower and its consolidated Subsidiaries as at November 22, 2002 and
the related unaudited consolidated statements of income and of cash flows for
the twenty-six (26) week period ended on such date, certified by a Responsible
Officer, copies of which have heretofore been furnished to the Bank, are
complete and correct and present fairly the consolidated financial condition of
the Borrower and its consolidated Subsidiaries at such date, and the
consolidated results of their operations and their consolidated cash flows for
the twenty-six (26) week period then ended (subject to normal year-end audit
adjustments). All such financial statements have been prepared in accordance
with GAAP applied consistently throughout the periods involved (except (i) as
approved by such Responsible Officer and as disclosed therein and (ii) for the
exclusion of footnotes required by GAAP). Neither the Borrower nor any of its
consolidated Subsidiaries had, as of November 22, 2002, any material Contingent
Obligation, or material liability for taxes, or any long-term lease or unusual
forward or long-term commitment, including, without limitation, any Interest
Hedge Agreement, which has not been disclosed to the Bank in writing by the
Borrower.

             (c) No Sales or Acquisitions. During the period from February 22,
2002, to and including the date hereof there has been no sale or other
disposition by the Borrower or any of its 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 at February 22, 2002.

                                       31



             (d) Financial Projections. The Borrower has delivered to the Bank
financial projections of the income statements of the Borrower for each fiscal
quarter through February 28, 2004 (the "Financial Projections"). The Financial
Projections represent a reasonable range of possible results in light of the
history of the business, present and foreseeable conditions and the intentions
of the Borrower's management as of the Closing Date.

         3.2 No Change. Except as set forth on Schedule 3.2, since February 22,
2002, there has been no Material Adverse Change and there has been no
development or event nor any prospective development or event which has had or
could reasonably be expected individually or in the aggregate to have a Material
Adverse Effect.

         3.3 Existence; Compliance with Law. Each of the Borrower and each
Guarantor (a) is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, (b) has the power and authority,
and the legal right, to own and operate its property, to lease the property it
operates as lessee and to conduct the business in which it is currently engaged,
(c) is duly qualified and in good standing under the laws of each jurisdiction
where its ownership, lease or operation of property or the conduct of its
business requires such qualification, except where such non-qualification would
not have a Material Adverse Effect, and (d) is in material compliance with all
Requirements of Law.

         3.4 Power; Authorization; Enforceable Obligations. Each of the Borrower
and each Guarantor has the power, authority, and legal right, to make, deliver
and perform this Agreement, each Application and each other Loan Document to
which it is a party (including, with respect to the Borrower, to borrow
hereunder). The Borrower has taken all necessary action to authorize the
borrowings on the terms and conditions of this Agreement, each Application and
each other Loan Document to which it is a party. No consent or approval or
authorization of, filing with or other act by or in respect of, any Governmental
Authority or any other Person (including shareholders and creditors of the
Borrower and each Guarantor) is required in connection with the borrowings
hereunder or with the execution, delivery, performance, validity or
enforceability of this Agreement, the Revolving Credit Note, each Application or
any other Loan Document. This Agreement has been and each Application and other
Loan Document to which it is a party will be, duly executed and delivered on
behalf of the Borrower. The Guaranty has been duly executed and delivered on
behalf of each Guarantor. This Agreement constitutes and each Application and
other Loan Document when executed and delivered will constitute, a legal, valid
and binding obligation of the Borrower, and in the case of the Guaranty, each
Guarantor, enforceable against the Borrower and each Guarantor, as the case may
be, in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law). No recording, filing, registration, notice or other similar action is
required in order to insure the legality, validity, binding effect or
enforceability of this Agreement or the Note or the other documents and
instruments executed hereunder as against all persons, other than such filings
as may be required under the UCC or in connection with the recording of
mortgages in favor of the Bank encumbering real property owned by the Borrower

                                       32


         3.5 No Legal Bar. The execution, delivery and performance of this
Agreement, the Revolving Credit Note, each Application and the other Loan
Documents by the Borrower and each Guarantor, the borrowings hereunder, the use
of the proceeds thereof and the consummation of the transactions herein or
therein contemplated (a) will not violate or materially conflict with any
Requirement of Law or Contractual Obligation (including any Licenses) of the
Borrower or any Guarantor and (b) will not result in, or require, the creation
or imposition of any Lien on any properties or revenues of the Borrower or any
Guarantor pursuant to any such Requirement of Law or Contractual Obligation.

         3.6 No Material Litigation. No litigation, investigation or proceeding
of or before any arbitrator or Governmental Authority is pending or, to the
knowledge of the Borrower, threatened against the Borrower or any Guarantor
against any of their respective businesses, operations, properties, prospects or
financial condition (a) with respect to this Agreement, the Revolving Credit
Note, the other Loan Documents or any of the transactions contemplated hereby,
or (b) as to which there is a reasonable likelihood of an adverse determination
and which, if adversely determined, could have a Material Adverse Effect. All
pending and, to the Borrower's knowledge, threatened material actions, suits,
proceedings and investigations affecting the Borrower or any Guarantor in
existence on the Closing Date are set forth on Schedule 3.6.

         3.7 No Default. Except as set forth on Schedule 3.7, neither the
Borrower nor any Guarantor is in default under or with respect to any of its
Contractual Obligations in any respect which could reasonably be expected to
have a Material Adverse Effect. No Default or Event of Default has occurred and
is continuing.

         3.8 Taxes. Each of the Borrower and each Guarantor has filed or caused
to be filed all tax returns which are required to be filed and have paid all
taxes shown to be due and payable on said returns or on any assessments made
against it or any of its property and all other taxes, fees or other charges
imposed on it or any of its property by any Governmental Authority (other than
any the amount or validity of which are currently being contested in good faith
by appropriate proceedings and with respect to which reserves, if any, in
conformity with GAAP have been provided on the books of the Borrower); no tax
Lien has been filed against the Borrower or any Guarantor, and, to the knowledge
of the Borrower, no claim is being asserted, with respect to any such tax, fee
or other charges.

         3.9 Federal Regulations. No part of the proceeds of any Loans will be
used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U or for any purpose which
violates the provisions of Regulation U or any other Regulations of the Board of
Governors of the Federal Reserve System. If requested by the Bank, the Borrower
will furnish to the Bank a statement to the foregoing effect in conformity with
the requirements of FR Form U- l referred to in said Regulation U. No part of
the proceeds of the Loans hereunder will be used for any purpose which violates,
or which is inconsistent with, the provisions of either of Regulations T and X.

                                       33


        3.10 ERISA. Each Plan (such representations in respect of any
Multiemployer Plan being made to the best knowledge of the Borrower) has
complied in all material respects with the applicable provisions of ERISA and
the Code. No "prohibited transaction" or "accumulated funding deficiency" (each
as defined in subsection 7.1(j)) or Reportable Event has occurred with respect
to any Single Employer Plan. The present value of all accrued benefits under
each Single Employer Plan of which the Borrower or a Commonly Controlled Entity
is a sponsor (based on those assumptions used to fund the Plans), as calculated
by the Borrower's actuaries, did not, as of the last annual valuation date prior
to the date on which this representation is made or deemed made, exceed the
value of the assets of the Plans allocable to such benefits. 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 under ERISA to any liability if the
Borrower or any such Commonly Controlled Entity were to withdraw completely from
any Multiemployer Plan as of the valuation date most closely preceding the date
this representation is made or deemed made. Such Multiemployer Plans are neither
in Reorganization as defined in Section 4241 of ERISA nor Insolvent as defined
in Section 4245 of ERISA. 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. Neither the Borrower nor any Commonly
Controlled Entity has any or has received notice of any liability under the Coal
Industry Retiree Health Benefit Act of 1992. Neither a Reportable Event nor an
"accumulated funding deficiency" (as defined in Subsection 7.1(j)) has occurred
during the five-year period to the date on which this representation is made or
deemed made with respect to any Single Employer Plan or Multiemployer Plan. No
termination of a Single Employer Plan has occurred, and no Lien on assets of the
Borrower or any Commonly Controlled Entity in favor of the PBGC or a Plan has
arisen during such five- year period.

        3.11 Investment Company Act; Public Utility Holding Company Act;
Regulation O.

             (a) Neither the Borrower nor any Guarantor is an "investment
company", or a company "controlled" by an "investment company", within the
meaning of the Investment Company Act of 1940, as amended.

             (b) Neither the Borrower nor any Guarantor is subject to regulation
as a "holding company", subject to regulation as an "affiliate" of a company",
or subject to regulation as a "subsidiary company" of a "holding company", in
each case under the Public Utility Holding Company Act of 1935, as amended.

             (c) To the knowledge of the Borrower, no executive officer or
principal shareholder of the Borrower is a director, executive officer or
principal shareholder of the Bank and no director of any Bank is in control of
the Borrower. For the purposes of this Section, the terms "director" (when used
with reference to the Bank), "executive officer", "principal shareholder" and
"control" of the Bank have the respective meanings assigned thereto in
Regulation O issued by the Board of Governors of the Federal Reserve System.

        3.12 Purpose of Loans. The proceeds of the Loans shall be used by the
Borrower only for the purposes permitted under Section 2.19.

                                       34


        3.13 Environmental Matters. Except as set forth on Schedule 3.13:

             (a) To the best of Borrower's knowledge, the Properties do not
contain, in, on, or under, including, without limitation, the soil and
groundwater thereunder, any Materials of Environmental Concern in amounts or
concentrations that constitute a violation of, or reasonably could give rise to
liability under Environmental Laws.

             (b) The Properties and all operations and facilities at the
Properties are in compliance, and have in the last five years been in compliance
with all Environmental Laws, and to the best of Borrower's knowledge, there is
no contamination at, under or about the Properties or violation of any
Environmental Law with respect to the Properties or the business operated by the
Borrower and its Subsidiaries which could interfere with the continued operation
of any of the Properties or impair the fair saleable value of any thereof. The
Borrower has not assumed any liability of any Person under any Environmental
Law.

             (c) The Borrower has not received written notice and is not aware
of any claim, violation, alleged violation, non-compliance, investigation or
potential liability regarding environmental matters or compliance with
Environmental Law with regard to the Properties which has not been
satisfactorily resolved, nor is the Borrower aware or does it have reason to
believe that any such action is being contemplated, considered or threatened.

             (d) Materials of Environmental Concern have not been generated,
treated, stored, transported, disposed of, at, on, from or under any of the
Properties, nor have any Materials of Environmental Concern been transferred
from the Properties to any other location except in either case in compliance
with all applicable Environmental Laws and such that it could not reasonably be
expected to give rise to liability of Borrower or its subsidiaries under any
applicable Environmental Law.

             (e) There are no governmental, administrative actions or judicial
proceedings pending or, to the best of Borrower's knowledge, contemplated or
threatened under any Environmental Laws to which the Borrower is or will be
named as a party with respect to the Properties, nor to the best of Borrower's
knowledge are there any consent decrees or other decrees, consent orders,
administrative orders or other orders, or other administrative or judicial
enforcement requirements outstanding under any Environmental Law with respect to
any of the Properties.

             (f) To the best of Borrower's knowledge, there has been no release
or threat of release of Matters of Environmental Concern at or from the
Properties, or arising from or related to the operations of the Borrower in
connection with the Properties or otherwise in connection with the business
operated by the Borrower and its Subsidiaries in violation of or in amounts or
in a manner that could reasonably be expected to give rise to liability of the
Borrower or its subsidiaries under any Environmental Law.

             (g) Each of the representations and warranties set forth in
paragraphs 3.13(a) through 3.13(f) is true and correct with respect to each
Property.

                                       35


        3.14 No Material Misstatements. No financial statement, exhibit or
schedule furnished by or on behalf of the Borrower to the Bank in connection
with the negotiation of this Agreement, the Revolving Credit Note, any
Application or any other Loan Document contains any misstatement of fact, or
omitted or omits to state any fact necessary to make the statements therein not
misleading under the circumstances under which they were made or given, where
such misstatement or omission would be material with respect to the performance
of the Borrower of its obligations hereunder or thereunder. Prior to the date
hereof, the Borrower has disclosed to the Bank in writing any and all facts
which materially and adversely affect (to the extent the Borrower can as of the
date hereof reasonably foresee), the business, operations or financial condition
of the Borrower and its Subsidiaries taken as a whole, and the ability of the
Borrower to perform its obligations under this Agreement, the Note, each
Application and the other Loan Documents.

        3.15 Condition of and Title to Properties. The real property owned or
leased by the Borrower and any Guarantor in the United States as of the Closing
Date is described on Schedule 3.15 hereto. Each of the Borrower and each
Guarantor has good title to or valid leasehold interest in all properties,
assets and other rights which it purports to own or lease or which are reflected
as owned or leased on its books and records, free and clear of all Liens and
encumbrances except Permitted Liens, and subject to the terms and conditions of
the applicable leases. Except as described on Schedule 3.15, all leases of
property are in full force and effect. No consent under any lease is required in
connection with the consummation of the transactions contemplated hereby. Except
for financing statements evidencing Permitted Liens, no effective financing
statement under the Uniform Commercial Code is in effect in any jurisdiction and
no other filing which names the Borrower or any Guarantor as debtor or which
covers or purports to cover any of the assets of the Borrower or any Guarantor
is currently effective and on file in any state or other jurisdiction, and
neither the Borrower nor any Guarantor has signed any such financing statement
or filing or any security agreement authorizing any secured party thereunder to
file any such financing statement or filing. All of the assets and properties of
the Borrower and each Guarantor that are necessary for the operation of their
respective businesses are in good working condition and are able to serve the
functions for which they are currently being used, except for ordinary wear and
tear.

        3.16 Intellectual Property. Each of the Borrower and its Subsidiaries
owns, or is licensed to use, all material trademarks, tradenames, copyrights,
technology, know-how and processes necessary for the conduct of its business as
currently conducted (the "Intellectual Property"). Except as set forth on
Schedule 3.16, no claim has been asserted and is pending by any Person
challenging or questioning the use of any such Intellectual Property, nor does
the Borrower know of any valid basis for any such claim. The use of such
Intellectual Property by the Borrower and its Subsidiaries does not infringe the
rights of any Person, except for such claims and infringements that, in the
aggregate, do not have a Material Adverse Effect. To the best knowledge of the
Borrower, except as set forth on Schedule 3.16, no slogan or other advertising,
device, product, process, method, substance, part or component or other material
now employed, or now contemplated to be employed, by any of the Borrower and its
Subsidiaries infringes upon or conflicts with any rights owned by any other
Person, and no claim or litigation regarding any of the foregoing is pending or,
to the knowledge of the Borrower, threatened. No patent, invention, device,
application, and no statute, law, rule, regulation, standard or code involving
the Borrower's intellectual property is pending or, to the knowledge of the
Borrower, proposed, except where the consequences in the aggregate could not
reasonably be expected to have a Material Adverse Effect.

                                       36


        3.17 No Burdensome Restrictions. No Requirement of Law or Contractual
Obligation of the Borrower or any Guarantor could reasonably be expected to have
a Material Adverse Effect.

        3.18 Security Interests. (a) At all times after execution and delivery
of a Pledge Agreement by the pledgor thereunder and the delivery of the
certificates (if any) pledged thereunder, the security interests created for the
benefit of the Bank under such Pledge Agreement will constitute valid, perfected
security interests in the Capital Stock pledged thereunder, subject to no other
Liens.

             (b) At all times after execution and delivery of the Security
Documents (other than the Pledge Agreements) by the party or parties thereto and
completion of the filings and recordings listed on Schedule 3.18, the security
interests created for the benefit of the Bank pursuant to the Security Documents
(other than the Pledge Agreements) will constitute valid, perfected security
interests in the collateral subject thereto, subject to no other Liens
whatsoever, except Permitted Liens.

        3.19 Solvency. The Borrower is, and after giving effect to the receipt
and application of the initial Loans hereunder will be, solvent such that: (a)
the fair value of its assets (including without limitation the fair salable
value of the goodwill and other intangible property of the Borrower) is greater
than the total amount of its liabilities, including without limitation,
Contingent Obligations, (b) the present fair salable value of its assets
(including without limitation the fair salable value of the goodwill and other
intangible property of the Borrower) is not less than the amount that will be
required to pay the probable liability on its debts as they become absolute and
matured, and (c) it is able to realize upon its assets and pay its debts and
other liabilities and commitments (including Contingent Obligations) as they
mature in the normal course of business. The Borrower (a) does not intend to,
nor does it believe that it will, incur debts or liabilities beyond its ability
to pay as such debts and liabilities mature, and (b) is not engaged in a
business or transaction, or about to engage in a business or transaction, for
which its property would constitute unreasonably small capital after giving due
consideration to the prevailing practice and industry in which it is engaged.

        3.20 No Other Indebtedness. The Borrower does not have any outstanding
Indebtedness to any person or entity other than to the Bank hereunder, except
for such Indebtedness as is set forth on Schedule 3.20 hereto ("Permitted
Indebtedness").

        3.21 Insurance. The Borrower currently maintains insurance which meets
or exceeds the requirements of subsection 5.5 and the applicable insurance
requirements set forth in the other Loan Documents. Schedule 3.21 hereto lists,
as of the Closing Date, all insurance policies and other bonds to which the
Borrower is a party, all of which are valid and in full force and effect. No
written notice has been given or claim made and the Borrower has no knowledge
that any grounds exist to cancel or avoid any of such policies or bonds or to
reduce the coverage provided thereby or any replacements thereof. Such policies
and bonds or any replacements thereof provide adequate coverage from reputable
and financially sound insurers in amounts sufficient to insure the assets and
risks of the Borrower in accordance with prudent business practice in the
industry of the Borrower.

                                       37


        3.22 Subsidiaries. As of the Closing Date, the Borrower has no
Subsidiaries except for those set forth on Schedule 3.22, each of which was duly
formed and is existing under the law of the jurisdiction set forth opposite
their names. All of the issued and outstanding shares of Capital Stock of the
Subsidiaries are duly and validly authorized and issued and fully paid and
nonassessable and are owned by the Borrower, (except for directors qualifying
shares). As of the Closing Date, there are no options, warrants or other rights
outstanding to purchase any Capital Stock of any of the Subsidiaries, nor are
any securities of any of the Subsidiaries convertible into or exchangeable for
Capital Stock of the Subsidiaries except as referred to on Schedule 3.22.

        3.23 Business; Fictitious Names. The Borrower is engaged only in the
businesses described on Schedule 3.23. Neither the Borrower nor any Guarantor
operates or does business under any assumed, trade or fictitious names, except
as shown on Schedule 3.23.

        3.24 Compliance with Laws. Each of the Borrower and each Guarantor has
duly complied with, and its properties, business operations and leaseholds are
in compliance in all material respects with, all Requirements of Law applicable
to the Borrower and each Guarantor, its properties and the conduct of its
businesses. Neither the Borrower nor any Guarantor has received any notice, not
heretofore complied with, from any federal, state or local authority or any
insurance or inspection body to the effect that any of its properties,
facilities, equipment or business procedures or practices fail to comply with
any applicable law, ordinances, regulation, building or zoning law, or any other
requirement of any such authority or body.

        3.25 Labor Matters; Payment of Wages. Neither the Borrower nor any
Guarantor is a party to any collective bargaining agreement, and there are no
strikes, work stoppages, material grievances, disputes or controversies with any
union or any other organization of the Borrower's or any Guarantor's employees,
or threats of strikes, work stoppages or any asserted pending demands for
collective bargaining by any union or organization, except to the extent that
such strikes, work stoppages, material grievances, disputes or controversies
could not reasonably be expected to cause a Material Adverse Change. Neither the
Borrower nor any Guarantor has, within the two- year period preceding the
Closing Date, taken any action which would have constituted or resulted in a
"plant closing" or "mass layoff" within the meaning of the Federal Worker
Adjustment and Retraining Notification Act of 1988 or any similar Requirement of
Law. The procedures by which each of the Borrower and each Guarantor has hired
or will hire its employees comply and will comply in all material respects with
each collective bargaining agreement to which the Borrower or the Guarantor is a
party and any applicable Requirement of Law. Each of the Borrower or the
Guarantor is in compliance with the Fair Labor Standards Act, as amended, and
has paid all minimum and overtime wages required by law to be paid to its
respective employees, except for violations which could not have a Material
Adverse Effect.

        3.26 Fiscal Year. The Fiscal Year of the Borrower ends on the last
Friday in February.

        3.27 Authorizations. (a) Except as set forth on Schedule 3.27(a), each
of the Borrower and each Guarantor possesses all material Governmental Approvals
necessary for the operations of its business and is not in material violation
thereof. All such Governmental Approvals are in full force and effect, and no
event has occurred that permits, or after notice or lapse of time could permit,
the revocation, termination or material and adverse modification of any such
Governmental Approval.

                                       38


             (b) Except as set forth on Schedule 3.27(b), neither the Borrower
nor any Guarantor has knowledge of any investigation, notice of apparent
liability, violation, forfeiture or other order or complaint issued by or before
any Governmental Authority, or of any other proceedings of or before any
Governmental Authority, which could reasonably be expected to have a Material
Adverse Effect.

         All of the foregoing representations and warranties shall survive the
execution and delivery of the Note and the making by the Bank of the Loans
hereunder and shall continue in full force and effect so long as any
indebtedness or obligation of the Borrower to the Bank hereunder or otherwise is
outstanding or unperformed or this Agreement remains in effect.

Credit Note and the other Loan Documents. All of the rights granted to the Bank

Borrower concerning this Agreement or the other Loan Documents;

             (d) acknowledges and agrees that the choice of forum contained in
this subsection 8.12 shall not be deemed to preclude the enforcement of any
