indirectly, owned or controlled by a Borrower and/or one or more of its
Wholly-Owned Subsidiaries.

         2. THE WC LINE; THE EQUIPMENT LINE; USE OF PROCEEDS.

                  2.1 WC LINE OF CREDIT.

                            (a) Bank will establish for Borrowers for and during
the WC Line Contract Period, subject to the terms and conditions hereof, a
revolving line of credit (the "WC LINE") pursuant to which Bank will from time
to time make Advances to Borrowers in a principal amount not exceeding at any
one time outstanding in the aggregate the lesser of the: (i) Borrowing Base
Amount, or (ii) Maximum WC Line Amount. Within the limitations set forth above,
Borrowers may borrow, repay and reborrow under the WC Line. The WC Line shall be
subject to all terms and conditions set forth in all of the Loan Documents,
which terms and conditions are incorporated herein. Borrowers' obligation to
repay Advances under the WC Line shall be evidenced by Borrowers' promissory
note (the "WC LINE NOTE") in the face amount of Five Million Dollars
($5,000,000.00), which shall be in the form attached hereto as EXHIBIT "A", with
the blanks appropriately filled in. At the end of the WC Line Contract Period,
the WC Line shall be subject to review and renewal, at the sole discretion of
Bank.

                            (b) Subsequent to the date hereof, and to the extent
permitted by this Agreement, Borrowers intend to seek additional equity and/or
Subordinated Debt for the purposes of financing the construction of Phase II at
Arkansas Lime's facility located at Batesville, Arkansas (the "ADDITIONAL
FUNDING"). If Borrowers obtain the Additional Funding (or commitments therefor
reasonably satisfactory to Bank) in an amount equal to or greater than Ten
Million Dollars ($10,000,000.00), Bank will, at Borrowers' request and upon
receipt of evidence reasonably satisfactory to Bank of the existence of the
Additional Funding, increase the Maximum WC Line Amount to Six Million Dollars
($6,000,000.00), provided that no Default or Event of Default shall have
occurred and be continuing. Contemporaneously with such increase, Borrowers
shall execute and deliver to Bank an Allonge to the WC Line Note in form and
content reasonably satisfactory to Bank evidencing the increased WC Line Maximum
Amount.

                  2.2 LETTERS OF CREDIT. Bank, at its sole discretion, may issue
for the account of Borrowers under the WC Line standby letters of credit in form
and content satisfactory to Bank, at its sole discretion. Notwithstanding the
foregoing, at no time shall the (i) aggregate face amount of all outstanding
letters of credit issued under the WC Line exceed the Letter of Credit Sublimit;
and (ii) principal balance of the WC Line, plus the aggregate face amount of all
outstanding letters of credit issued under the WC Line, exceed the lesser of the
(A) Borrowing Base Amount or (B) Maximum Line Amount.

                            Borrowers will execute a letter of credit
application and letter of credit agreement, and such other documents as may be
required by Bank in connection with the issuance of letters of credit hereunder
in substantially the form attached hereto as EXHIBIT "D". The outstanding face
amount of all letters of credit issued by Bank pursuant hereto will reduce
Borrowers' ability to borrow under the WC Line as if such face amount were an
Advance under the Line. In the event that Bank pays any sums due pursuant to
such letters of credit for any reason, such payment shall be deemed to be an
Advance under the WC Line repayable by Borrowers pursuant to the terms hereof.

                            In the event that the WC Line is terminated for any
reason or demand is made thereunder, Borrowers will deposit with Bank in an
interest bearing account an amount equal to the face amount of all letters of
credit then outstanding which have been issued hereunder, plus all fees related
thereto or to accrue thereunder. Such funds will be held by Bank as cash
collateral to secure Borrowers' obligations hereunder.

                            Borrowers hereby assume all risks of the acts or
omissions of Bank and any beneficiary of any letter of credit issued by Bank.
Without limiting the generality of the foregoing, Borrowers hereby indemnify and
hold harmless Bank and any shareholder, officer, director, official, agent,
employee and attorney of Bank and any of their respective heirs, executors,
administrators, successors and assigns (collectively, for this paragraph, the
"INDEMNITEES") from and against any



                                       9
<PAGE>

and all claims, damages, losses, liabilities, costs or expenses whatsoever by
reason of or in connection with the execution and delivery or transfer of, or
payment or failure to pay under, any letter of credit issued by Bank or any
Indemnitee entering into any transaction described herein provided, however, the
Borrower shall not be required to indemnify any Indemnitee for any claims,
damages, losses, liabilities, costs or expenses to the extent, but only to the
extent, caused by the willful misconduct or gross negligence of such Indemnitee.

                  2.3 EQUIPMENT LINE OF CREDIT

                            (a) Bank will establish for Borrowers for and during
the Equipment Line Advance Period, subject to the terms and conditions hereof, a
revolving discretionary equipment line facility (the "EQUIPMENT LINE") pursuant
to which Bank may, from time to time, in its sole and absolute discretion, make
loans to Borrowers in a principal amount not to exceed at any one time
outstanding in the aggregate the Maximum Equipment Line Amount. Each Advance
under the Equipment Line shall be in an amount not to exceed (i) one hundred
percent (100%) of the Eligible Equipment Costs with respect to new equipment and
(ii) eighty percent (80%) of the Eligible Equipment Costs with respect to used
equipment. Within the limitations set forth above, Borrowers may borrow, repay
and reborrow under the Equipment Line. Each Advance under the Equipment Line
shall be evidenced by a promissory note (individually and collectively the
"EQUIPMENT LINE NOTE") in the original principal amount of such Advance, which
promissory note shall be (A) in form and content satisfactory to Bank and (B)
executed and delivered by Borrowers to Bank contemporaneously with or prior to
such Advance. The Equipment Line shall be subject to the review and renewal at
the sole discretion of Bank.

                            (b) In addition to cash Advances made by Bank under
the Equipment Line, Bank may, from time to time, in its sole and absolute
discretion, at the request of Borrowers, enter into equipment leases with
Borrowers under the Equipment Line, which leases shall be in form and content
satisfactory to Bank in its sole discretion. The amount available under the
Equipment Line shall be reduced by an amount equal to the actual cost related to
the equipment subject to the lease paid by the equipment lessor.

                            (c) Borrowers acknowledge and agree that the
Equipment Line is a discretionary facility and Bank may determine not to make an
Advance thereunder for any or no reason.

                  2.4 USE OF PROCEEDS. Borrowers agree to use Advances under the
(a) WC Line for working capital purposes and to refinance certain obligations of
Borrowers under the Credit Agreement or the Borrowers' existing revolving credit
facility with Wachovia Bank, National Association, or both, and (b) Equipment
Line to finance new and used mobile equipment used in Borrowers' mining or
quarrying operations.

                  2.5 METHOD OF ADVANCES.

                            (a) WC LINE ADVANCES. On any Business Day, Borrowers
may request an Advance under the WC Line no later than 11:00 a.m. Philadelphia
time on the Business Day such Advance is requested to be funded, by delivering
to Bank such documentation as Bank may from time to time require. Subject to the
terms and conditions of this Agreement, Bank may make the proceeds of an Advance
available to Borrowers by crediting such proceeds to a deposit account of a
Borrower maintained with Bank specified by all of them or, if such Advance is
made within sixty (60) days of the date hereof, with another banking institution
specified by Borrowers. Each request for an Advance under the WC Line shall be
made by the chief executive officer or the chief financial officer of a
Borrower. However, Bank may require that specified officers of Borrowers sign
each request for advance.

                            (b) EQUIPMENT LINE ADVANCES. On any Business Day,
Borrowers may request an Advance under the Equipment Line by delivering a
written request therefor to Bank, together with the invoice and such other
documentation as Bank may request in connection with the equipment to be
financed with the requested Advance. Such written request shall specify the date
on which Borrowers request such advance to be funded, which date shall not be
earlier than three (3) Business Days after the Business Day on which Bank
receives the Advance request. Each request for an Advance under the Equipment
Line shall be made by the chief executive officer or the chief financial officer
of a Borrower. However, Bank may require that specified officers of Borrowers
sign each request for an advance.

                  3.4 INTEREST RATE ELECTIONS - EQUIPMENT LINE.

                            (a) If Borrowers desire that all or part of the
Advances under the Equipment Line accrue interest at the LIBOR Rate, Borrowers

Notification, that portion of the principal balance outstanding under the
Equipment Line identified in such LIBOR Rate Notification shall accrue interest
at the LIBOR Rate as follows: (i) with respect to the principal amount of any
new Advance under the Equipment Line, from the date of such Advance until the
end of the one month Interest Period with respect thereto; and/or (ii) with

respect thereto; and/or (iii) with respect to all or any portion of the
Equipment Line Advances outstanding and accruing interest at the Prime Rate at
the time of the LIBOR Rate Notification related to such Advances, from the date

                            (b) If Borrowers desire that an Advance under the
Equipment Line accrue interest at the Fixed Rate, Borrowers shall notify Bank of
such election at the time of the request for such Advance.

principal of the WC Line for various Interest Periods; (c) the Interest Periods
for the WC Line shall be either one (1), two (2) or three (3) months; (d) the
Interest Period for the Equipment Line shall be one (1) month only; (e) the
LIBOR Rate applicable to any portion of the outstanding principal of the WC Line
and the Equipment Line may be different from the LIBOR Rate applicable to any
other portion of the outstanding principal of the WC Line and the Equipment
Line; (f) individual portions of the WC Line accruing interest at the LIBOR Rate
must be in amounts of at least Five Hundred Thousand Dollars ($500,000.00) each
and in increments of Two Hundred Fifty Thousand Dollars ($250,000.00); (g)
individual portions of the Equipment Line accruing interest at the LIBOR Rate
must be in amounts of Two Hundred Fifty Thousand Dollars ($250,000.00) each and
in increments of Fifty Thousand Dollars ($50,000.00) thereof; and (h) the LIBOR
Rate shall not be available at any time during the continuation of an Event of
Default.

                  3.6 FALL BACK RATE.

                            (a) Working Capital Line. After expiration of any
Interest Period, any principal portion of the Advances under the WC Line
corresponding to such Interest Period which has not been converted or renewed in
accordance with the terms of this Agreement shall accrue interest automatically
at the LIBOR Market Index Rate from the date of expiration of such Interest
Period until paid in full, unless and until receipt by Bank of a request for
another interest rate in accordance with the terms of this Agreement.

                            (b) Equipment Line. After expiration of any Interest
Period, any principal portion of the Advances under the Equipment Line
corresponding to such Interest Period which has not been converted or renewed in
accordance with the terms of this Agreement shall accrue interest automatically

in full, unless and until receipt by Bank of a request for another interest rate
in accordance with the terms of this Agreement.

                  3.7 LIBOR RATE BORROWINGS. No more than four (4) separate
borrowings in the aggregate accruing interest at the LIBOR Rate may be
outstanding at any one time under the WC Line. Such limit shall not apply to
Advances accruing interest at the LIBOR Market Index Rate.

                  3.8 LIBOR OR LIBOR MARKET INDEX RATE UNLAWFUL. In the event
that, as a result of any changes in applicable law or regulation or the
interpretation thereof, it becomes unlawful for Bank to maintain or fund any
Advance under the LIBOR Rate or the LIBOR Market Index Rate, then Bank shall
immediately notify Borrower thereof and Bank's obligation to make, convert to,
or maintain any Advance at the LIBOR Rate or the LIBOR Market Index Rate shall
be suspended until such time as Bank may again cause the LIBOR Rate or the LIBOR
Market Index Rate to be applicable and, until such time, Advances subject to the
LIBOR Rate or the LIBOR Market Index Rate shall accrue interest at the LIBOR
Market Index Rate, if available, and, if the



                                       12
<PAGE>

LIBOR Market Index Rate is not available, the Prime Rate. Promptly after
becoming aware that it is no longer unlawful for Bank to maintain or fund
Advances at the LIBOR Rate or the LIBOR Market Index Rate, Bank shall notify
Borrowers thereof and such suspension shall cease to exist.

                  3.9 LIBOR RATE UNASCERTAINABLE OR UNAVAILABLE. If, at any
time, Bank in good faith shall determine (which determination shall be
conclusive in the absence of manifest error) that the LIBOR Rate or the LIBOR
Market Index Rate is unavailable or adequate means for ascertaining the LIBOR
Rate or the LIBOR Market Index Rate do not exist, Bank shall promptly notify
Borrowers of such determination. Upon such determination, the right of Borrowers
to select, maintain and/or convert to the LIBOR Rate or the LIBOR Market Index
Rate shall be suspended until notice from Bank that the LIBOR Rate or the LIBOR
Market Index Rate is again available or ascertainable and, until such time, all
outstanding Advances shall accrue interest at the LIBOR Market Index Rate, if
available, and, if the LIBOR Market Index Rate is not available, the Prime Rate.

                  3.10 DEFAULT INTEREST. Interest will accrue on the principal
balance of the WC Line and the Equipment Line after the occurrence of an Event
of Default at a rate which is three percent (3%) in excess of the Prime Rate in
effect from time to time.

                  3.11 POST JUDGMENT INTEREST. Any judgment obtained for sums
due hereunder or under the other Loan Documents will accrue interest at the
default rate set forth above until paid.

                  3.12 CALCULATION. Interest will be computed on the basis of a
year of 360 days and paid for the actual number of days elapsed.

                  3.13 LIMITATION OF INTEREST TO MAXIMUM LAWFUL RATE. In no
event will the rate of interest payable hereunder exceed the maximum rate of
interest permitted to be charged by applicable law (including the choice of law
rules) and any interest paid in excess of the permitted rate will be refunded to
Borrowers. Such refund will be made by application of the excessive amount of
interest paid against any sums outstanding hereunder and will be applied in such
order as Bank may determine. If the excessive amount of interest paid exceeds
the sums outstanding, the portion exceeding the sums outstanding will be
refunded in cash by Bank. Any such crediting or refunding will not cure or waive
any default by Borrowers. Borrowers agree, however, that in determining whether
or not any interest payable hereunder exceeds the highest rate permitted by law,
any non-principal payment, including without limitation prepayment fees and late
charges, will be deemed to the extent permitted by law to be an expense, fee,
premium or penalty rather than interest.

         4. PAYMENTS AND FEES.

                  4.1 INTEREST PAYMENTS ON THE WC LINE. Borrowers will pay
interest on outstanding Advances under the WC Line (a) accruing interest at the
Prime Rate or the LIBOR Market Index Rate monthly on the first Business Day of
each calendar month commencing on the first day of the first calendar month
following the date hereof, and (b) accruing interest at the LIBOR Rate on the
last Business Day of the applicable Interest Period.

                  4.2 PRINCIPAL PAYMENTS ON THE WC LINE. Borrowers will pay the
outstanding Advances under the WC Line, together with any accrued and unpaid
interest thereon, and any other sums due pursuant to the terms hereof, ON DEMAND
after the occurrence of an Event of Default or after expiration of the WC Line
Contract Period. If any Out-Of-Formula Advance arises or exists under the WC
Line for any reason whatsoever, including inventory or accounts becoming
ineligible, Borrowers will repay such Out-Of-Formula Advance immediately,
without demand.

                  4.3 PRINCIPAL AND INTEREST PAYMENTS ON THE EQUIPMENT LINE.
Borrowers will pay principal and interest on individual Advances under the
Equipment Line when and as provided for under the applicable Equipment Note;
provided, however, the maximum repayment term for any Advance under the
Equipment Line shall be five (5) years.

                  4.4 LATE CHARGE. In the event that Borrowers fail to pay any
principal, interest or other fees or expenses payable hereunder or under any of
the other Loan Documents for a period of at least fifteen (15) days after any
such payment is first due, in addition to paying such sums, Borrower will pay to
Bank a one time late charge for each late payment equal to five percent (5%), of
such past due payment as compensation for the expenses incident to such past due
payment.



                                       13
<PAGE>

                  4.5 PREPAYMENT. Borrowers may terminate or prepay all or any
part of the principal balance of the WC Line or the Equipment Line at any time.
In the event of any prepayment of all or any portion of the Equipment Line,
Borrowers shall also pay to Bank, contemporaneously therewith, the prepayment
premium, if any, set forth in any applicable Equipment Line Note.

                  4.6 LETTER OF CREDIT FEES. For each issuance or renewal of a
letter of credit, Borrowers will pay to Bank an issuance or renewal fee in an
amount equal to Bank's standard letter of credit fees in effect from time to
time, payable coincident with and as a condition of the issuance or renewal of
such letter of credit. In addition, Borrowers shall pay such other fees and
charges in connection with the negotiation or cancellation of each letter of
credit as may be customarily charged by Bank. Such fees shall be computed on the
basis of a year of 360 days.

                  4.7 UNUSED FEE. Borrowers shall pay to Bank, quarterly in
arrears on the first Business Day of each calendar quarter, a fee equal to 1/4
of 1% of the amount, if any, by which the (a) Maximum WC Line Amount exceeds (b)
average outstanding principal balance of all WC Line Advances and the undrawn
face amount of all letters of credit issued under this Agreement for the last
preceding fiscal quarter.

                  4.8 FIELD EXAM AND APPRAISAL FEES. Upon the occurrence and
during the continuance of an Event of Default, Borrowers shall pay to Bank, to
the extent that such examinations or appraisals are actually conducted, (a)
field examination fees and (b) appraisal fees, in each case in accordance with
Bank's schedule of fees in effect from time to time (or, if the appraisal was
performed by a third party, the amount charged by such third party), in
connection with field exams and appraisals of Borrowers' books and records and
such other matters as Bank shall deem appropriate, plus all out-of-pocket
expenses incurred by Bank in connection with such field examinations and
appraisals.

                  4.9 PAYMENT METHOD. Borrowers irrevocably authorize Bank to
debit all payments required to be made by Borrowers hereunder or under the WC
Line or the Equipment Line on the date due from any deposit account maintained
by any Borrower with Bank. Otherwise, Borrowers will be obligated to make such
payments directly to Bank. All payments are to be made in immediately available
funds. If Bank accepts payment in any other form, such payment shall not be
deemed to have been made until the funds comprising such payment have actually
been received by or made available to Bank.

                  4.10 APPLICATION OF PAYMENTS. Any and all payments on account
of the WC Line or the Equipment Line will be applied to accrued and unpaid
interest, outstanding principal and other sums due hereunder or under the Loan
Documents, in such order as Bank, in its discretion, elects. If Borrowers make a
payment or payments and such payment or payments, or any part thereof, are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or are required to be repaid to a trustee, receiver, or any other person under
any bankruptcy act, state or federal law, common law or equitable cause, then to
the extent of such payment or payments, the obligations or part thereof
hereunder intended to be satisfied shall be revived and continued in full force
and effect as if said payment or payments had not been made.

                  4.11 LOAN ACCOUNT. Bank will open and maintain on its books a
loan account (the "LOAN ACCOUNT") with respect to Advances made, repayments,
prepayments, the computation and payment of interest and fees and the
computation and final payment of all other amounts due and sums paid to Bank
under this Agreement. Except in the case of manifest error, the Loan Account
will be conclusive and binding on the Borrowers as to the amount at any time due
to Bank from Borrowers under this Agreement or the WC Line Note and any
Equipment Line Note.

                  4.12 INDEMNITY; LOSS OF MARGIN. Borrowers will indemnify Bank
against any loss or expense which Bank sustains or incurs as a consequence of an
Event of Default, including, without limitation, any failure of Borrowers to pay
when due (at maturity, by acceleration or otherwise) any principal, interest,
fee or any other amount due under this Agreement or the other Loan Documents. If
Bank sustains or incurs any such loss or expense it will from time to time
notify Borrowers in writing of the amount determined in good faith by the Bank
to be necessary to indemnify Bank for the loss or expense. Such amount will be
due and payable by Borrowers to Bank within ten (10) days after presentation by
Bank of a statement setting forth a brief explanation of and Bank's calculation
of such amount, which statement shall be conclusively deemed correct absent
manifest error. Any amount payable to the Bank under this Section will bear
interest at the default



                                       14
<PAGE>

rate payable pursuant to SECTION 3.10 hereof from the due date until paid, both
before and after judgment.

                            In the event that any present or future law, rule,
regulation, treaty or official directive or the interpretation or application
thereof by any central bank, monetary authority or governmental authority, or
the compliance with any guideline or request of any central bank, monetary
authority or governmental authority (whether or not having the force of law):

                            (a) subjects Bank to any tax with respect to any
amounts payable under this Agreement or the other Loan Documents by Borrowers or
otherwise with respect to the transactions contemplated under this Agreement or
the other Loan Documents (except for taxes on the overall net income of Bank
imposed by the United States of America or any political subdivision thereof);
or

                            (b) imposes, modifies or deems applicable any
deposit insurance, reserve, special deposit, capital maintenance, capital
adequacy, or similar requirement against assets held by, or deposits in or for
the account of, or loans or Advances or commitment to make loans or Advances by,

Bank; or

Bank with respect to any Advances or extensions of credit or commitments to make
Advances or extensions of credit under this Agreement, Bank shall so notify
Borrowers in writing. Borrowers agree to pay Bank the amount of such increase in
cost, reduction in income, reduced return on equity or capital, or additional
expense within ten (10) days after presentation by Bank of a statement
concerning such increase in cost, reduction in income, reduced return on equity
or capital, or additional expense. Such statement shall set forth a brief
explanation of the amount and Bank's calculation of the amount (in determining
such amount the Bank may use any reasonable averaging and attribution methods),
which statement shall be conclusively deemed correct absent manifest error. If
the amount set forth in such statement is not paid within ten (10) days after
such presentation of such statement, interest will be payable on the unpaid
amount at the default rate payable pursuant to SECTION 3.10 hereof from the due
date until paid, both before and after judgment.

The foregoing indemnity shall survive the occurrence of any event whatsoever,
including, without limitation, payment of the Bank Indebtedness or any
investigation by or knowledge of Bank.

                  7.7 COMPLIANCE WITH ERISA. In addition to and without limiting
the generality of SECTION 7.5, to the extent that the failure to do so could
result in a Material Adverse Effect (a) comply with all applicable provisions of
ERISA and the regulations and published interpretations thereunder with respect
to all Employee Benefit Plans, (b) not take any action or fail to take action
the result of which could be a liability to the PBGC or to a Multiemployer Plan,
(c) not participate in any prohibited transaction that could result in any civil

information about any Employee Benefit Plan as may be reasonably requested by
Bank.

                  7.8 COMPLIANCE WITH AGREEMENTS. Comply in all material

                  7.11 FURTHER ASSURANCES. Make, execute and deliver all such
additional and further acts, things, deeds and instruments as the Bank may
reasonably require to document and consummate the transactions contemplated
hereby and to vest completely in and assure the Bank their respective rights
under this Agreement and the other Loan Documents.

                  7.12 INSURANCE. Borrowers will carry adequate insurance issued
by an insurer acceptable to Bank, in amounts reasonably acceptable to Bank (at
least adequate to comply with any co-insurance provisions) and against all such
liability and hazards as are usually carried by entities engaged in the same or
a similar business similarly situated. Business interruption insurance shall be
carried by the Borrowers in an amount usually carried by entities engaged in the
same or similar business similarly situated. In the case of insurance on any of
the Collateral, Borrowers shall carry insurance in the full insurable value
thereof and cause Bank to be named as loss payee (with a lender's loss payable
endorsement), and additional insured with respect to all liability insurance, as
its interests may appear with thirty (30) days' notice to be given Bank by the
insurance carrier prior to cancellation or material modification of such
insurance coverage.

                            Borrowers shall cause to be delivered to Bank the
insurance policies therefor or, in the alternative, evidence of insurance and
within thirty (30) days after the expiration of any such insurance, additional
policies or duplicates thereof or, in the alternative, evidence of insurance
evidencing the renewal of such insurance and payment of the premiums therefor.
Borrowers shall direct all insurers that, in the event of any loss thereunder in
respect of the Collateral, the insurers shall make payments for such loss
directly to Bank and not to Borrowers and Bank jointly.

                            In the event of any loss in respect of the
Collateral, such Borrowers will give Bank immediate notice thereof and Bank may
make proof of loss whether the same is done by Borrowers. Bank is granted a
power of attorney by each Borrower with full power of substitution to file any
proof of such loss in such Borrower's or Bank's name, to endorse such Borrower's
name on any check, draft or other instrument evidencing insurance proceeds, and
to take any action or sign any document to pursue any insurance loss claim. Such
power being coupled with an interest is irrevocable.

                            In the event of any loss in respect of the
Collateral, Bank, at its option, may retain and apply all or any part of the
insurance proceeds to reduce, in such order and amounts as Bank may elect, the
Bank Indebtedness, provided that so long as there does not exist at the time any
Default, Event of Default or Out-of-Formula Advance and the amount of the
proceeds in question is not greater than Two Hundred Fifty Thousand Dollars
($250,000.00), the Bank, at the request of the affected Borrower, will disburse
all or any part of such insurance proceeds to or for the benefit of any Borrower
for the purpose of repairing or replacing Collateral after receiving proof
satisfactory to Bank of such repair or replacement, in either case without
waiving or impairing the Bank Indebtedness or any provision of this Agreement.
No Borrower shall take out any insurance in respect of the Collateral without
having Bank named as lender's loss payee thereon. Borrowers shall bear the full
risk of loss from any loss of any nature whatsoever with respect to the
Collateral.

                  7.13 ADDITIONAL DOCUMENTS AND FUTURE ACTIONS. Borrowers will,
at their sole cost, take such actions and provide Bank from time to time with
such agreements, financing statements and additional instruments, documents or
information as the Bank may in its reasonable discretion deem necessary or
advisable to perfect, protect, maintain or enforce the security interests in the
Collateral, to permit Bank to protect or enforce its interest in the Collateral,
or to carry out the terms of the Loan Documents. Each Borrower hereby authorizes
and appoints Bank as its attorney-in-fact, with full power of substitution, to
take such actions as Bank may deem advisable to protect the Collateral and its
interests therein and its rights hereunder, to execute on such Borrower's behalf
and file at such Borrower's expense financing statements, and amendments
thereto, in those public offices deemed necessary or appropriate by Bank to
establish, maintain and protect a continuously perfected security interest in
the Collateral, and to execute on such Borrower's behalf such other documents
and notices as Bank may deem advisable to protect the Collateral and its
interests therein and its rights hereunder. Such power being coupled with an
interest is irrevocable. Each Borrower irrevocably authorizes the filing of a
carbon, photographic or other copy of this Agreement, or of a financing
statement, as a financing statement and agrees that such filing is sufficient as
a financing statement.

                  7.14 ACCOUNTS RECEIVABLE. Upon request by Bank after the
occurrence of an uncured Event of Default, Borrowers will (a) inform Bank
immediately of the rejection of goods, claims made or delay in delivery or
performance in regard to any account or contract right upon


                                       22

adjust the borrowing base calculation under the WC Line to reduce the
availability for Advances under the WC Line by the amount of such account and
will repay any Out-Of-Formula Advance resulting therefrom; (b) except as may be
required by order of a court or other tribunal or otherwise by Applicable Law,
make no change in any account upon which Borrowers have based availability for
Advances under the WC Line, unless such change is reflected in the borrowing
base calculation and does not result in any Out-Of-Formula Advance under the
WC Line; (c) furnish to Bank all information received by either Borrower
affecting the financial standing of any account debtor whose account or contract
right has been specifically assigned to Bank; (d) pay Bank the amount loaned
against any account or contract right if the goods are returned by purchaser or
the contract is canceled or terminated or adjust the borrowing base calculation
to reduce the availability for advances under the WC Line by the amount of such
account and repay any Out-Of-Formula Advance resulting therefrom; (e)
immediately notify Bank if any of their accounts arise out of contracts with the
United States or any department, agency or instrumentality thereof, and execute
any instruments and take any steps required by Bank in order that all monies due
and to become due under such contract shall be assigned to Bank and notice
thereof given to the Government under the Federal Assignment of Claims Act; and
(f) deliver to Bank, with appropriate endorsement or assignment, any instrument
or chattel paper representing an account or contract right. Any permission
granted to Borrowers by Bank to omit any of the requirements of this
SECTION 7.14 may be revoked by Bank at any time.

                            Upon request by Bank after the occurrence of an
uncured Event of Default, Borrowers will (a) give Bank assignments, in form
acceptable to Bank, of specific accounts or groups of accounts and monies due
and to become due under specific contracts; (b) furnish to Bank a copy, with
such duplicate copies as Bank may request, of the invoice applicable to each
account specifically assigned to Bank or arising out of a contract right,
bearing a statement that such account has been assigned to Bank and such
additional statements as Bank may require; (c) mark its records evidencing its
accounts in a manner satisfactory to Bank so as to show which accounts have been
assigned to Bank; (d) furnish to Bank satisfactory evidence of the shipment and
receipt of any goods specified by Bank and the performance of any services or
obligations covered by accounts or contracts in which Bank has a security
interest; (e) pay Bank the unpaid portion of any account or contract right upon
which Borrowers have based availability for Advances under the WC Line if (i)
such account is not paid promptly after its due date, (ii) an account debtor
does not accept the goods or services, (iii) any petition under the Bankruptcy
Code or any similar Federal or State statute is filed by or against a purchaser,
or (iv) Bank shall at any time reject the account as unsatisfactory; and until
such payment is made by Borrowers, Bank may retain any such account or contract
right as security and may charge any deposit account of either Borrower with any
such amounts; (f) join with Bank in executing a notice, affidavit or similar
instrument, in form satisfactory to Bank, and other instruments as Bank may from
time to time reasonably request and pay the cost of filing the same in any
public office deemed advisable by Bank; (g) give Bank such financial statements,
reports, certificates, lists of purchasers (showing names, addresses, and
amounts owing) and other data concerning its accounts, contracts, collections,
inventory, and other matters as Bank may from time to time specify; (h)
segregate cash proceeds of Collateral so that they may be identified readily,
and deliver the same to the Bank at such time or times and in such manner and
form as the Bank may direct; (i) furnish such witnesses as may be necessary to
establish legal proof of the Collateral or records relating to the Collateral;
and (j) obtain from any owner, encumbrancer or other person having an interest
in the property where any Collateral is located, written consent to Bank's
removal of the Collateral therefrom, without liability on the part of the Bank
to such owner, encumbrancer or other person, or from any such owner,
encumbrancer or other person such waivers of any interest in the Collateral as
the Bank may require.

                  7.15 MAJOR BANK ACCOUNT. Within ninety (90) days of the date
hereof, Borrowers shall establish Bank as their primary cash management bank for
collection and disbursements to facilitate efficient application and management
of the loans and other extensions of credit hereunder and Borrowers shall
maintain Bank as such so long as the WC Line is in effect and Bank's fees and
charges to Borrowers are substantially similar to the fees and charges that Bank
is offering to its other customers for similar services.

         8. FINANCIAL COVENANTS

                  13.3 SALE OR OTHER DISPOSITION OF COLLATERAL. The sale, lease
or other disposition of the Collateral, or any part thereof, by Bank after an

without notice. The Bank may cause the Collateral to remain on Borrowers'
premises or otherwise or to be removed and stored at premises owned by other
persons, at Borrowers' expense, pending sale or other disposition of the
Collateral. Borrowers, at Bank's request, shall assemble the Collateral
consisting of inventory and tangible assets and make such assets available to

expenses related thereto including attorney fees, shall be applied in such order
as Bank, in its sole discretion, elects, toward satisfaction of the Bank
Indebtedness. Bank shall account to Borrowers for any surplus realized upon such
sale or other disposition, and Borrowers shall remain liable for any deficiency.
The commencement of any action, legal or equitable, or the rendering of any
judgment or decree for any deficiency shall not affect Bank's security interest
in the Collateral. Each Borrower agrees that Bank has no obligation, other than
to act in a commercially reasonable manner, to preserve rights to the Collateral
against any other parties. Bank is hereby granted a license or other right to
use, after an Event of Default, without charge, each Borrower's labels, general

the Collateral, in completing production of, advertising for sale and selling

contracts, licenses, approvals, permits, leases and franchise agreements shall
inure to Bank's benefit. Bank shall be under no obligation to marshal any assets

or all of the Bank Indebtedness.

                  13.4 ACTIONS WITH RESPECT TO ACCOUNTS. Each Borrower hereby

following actions, in its name or the name of Bank, as Bank may determine,
without notice to such Borrower and at such Borrower's expense:

         Each Borrower ratifies and approves all acts of said attorneys and
agrees that said attorneys shall not be liable for any acts of commission or
omission, nor for any error of judgment or mistake




                                       34
<PAGE>



of fact or law, except willful misconduct or gross negligence. This power, being
coupled with an interest, is irrevocable. Each Borrower agrees to assist the
Bank in the collection and enforcement of its accounts and not to hinder, delay
or impede the Bank in its collection or enforcement of said accounts.

                  13.5 SET-OFF. Without limiting the rights of Bank under
applicable law, Bank and any Affiliate of Bank has and may exercise a right of
set-off against all sums in deposit accounts of any Borrower maintained with
Bank or an Affiliate of Bank which contain proceeds of any of the Borrowers'
accounts. At any time and from time to time following the occurrence of an Event
of Default, Bank or such Affiliate may without notice or demand, set off and
apply any and all such sums at any time held by Bank or any such Affiliate of
Bank against any or all of the Bank Indebtedness.

                  13.6 TURNOVER OF PROPERTY HELD BY BANK. Each Borrower
irrevocably authorizes any Affiliate of Bank, upon and following the occurrence
of an Event of Default, at the request of Bank and without further notice, to
turn over to Bank any property of such Borrower held by such Affiliate,
including without limitation, funds and securities for such Borrower's account
and to debit, for the benefit of Bank, any deposit account maintained by such
Borrower with such Affiliate (even if such deposit account is not then due or
there results a loss or reduction of interest or the imposition of a penalty in
accordance with law applicable to the early withdrawal of time deposits), in the
amount requested by Bank up to the amount of the Bank Indebtedness, and to pay
or transfer such amount or property to Bank for application to the Bank
Indebtedness.

                  13.7 DELAY OR OMISSION NOT WAIVER. Neither the failure nor any
delay on the part of Bank to exercise any right, remedy, power or privilege
under the Loan Documents upon the occurrence of any Event of Default or
otherwise shall operate as a waiver thereof or impair any such right, remedy,
power or privilege. No waiver of any Event of Default shall affect any later
Event of Default or shall impair any rights of Bank. No single, partial or full
exercise of any rights, remedies, powers and privileges by the Bank shall
preclude further or other exercise thereof. No course of dealing between Bank
and any Borrower shall operate as or be deemed to constitute a waiver of Bank's
rights under the Loan Documents or affect the duties or obligations of
Borrowers.

                  13.8 REMEDIES CUMULATIVE; CONSENTS. The rights, remedies,
powers and privileges provided for herein shall not be deemed exclusive, but
shall be cumulative and shall be in addition to all other rights, remedies,
powers and privileges in Bank's favor at law or in equity.

                  13.9 CERTAIN FEES, COSTS, EXPENSES, EXPENDITURES AND
INDEMNIFICATION. Borrowers agree to pay on demand all costs and expenses of
Bank, including without limitation:

                            (a) all costs and expenses in connection with the
preparation, review, negotiation, execution, delivery and administration of the
Loan Documents, and the other documents to be delivered in connection therewith,
or any amendments, extensions and increases to any of the foregoing (including,
without limitation, reasonable attorney's fees and expenses, and the cost of
appraisals and reappraisals of Collateral), and the cost of periodic lien
searches and tax clearance certificates, as Bank deems advisable;

                            (b) all losses, costs and expenses in connection
with the enforcement, protection and preservation of the Bank's rights or
remedies under the Loan Documents, or any other agreement relating to any Bank
Indebtedness, or in connection with legal advice relating to the rights or
responsibilities of Bank (including without limitation court costs, reasonable
attorney's fees and expenses of accountants and appraisers); and

                            (c) any and all stamp and other taxes payable or
determined to be payable in connection with the execution and delivery of the
Loan Documents, and all liabilities to which Bank may become subject as the
result of delay in paying or omission to pay such taxes.

         In the event Borrowers shall fail to pay taxes, insurance, assessments,
costs or expenses which it is required to pay hereunder, or fails to keep the
Collateral free from security interests or liens (except as expressly permitted
herein), or fails to maintain or repair the Collateral as required hereby, or
otherwise breaches any obligations under the Loan Documents, Bank in its
discretion, may make expenditures for such purposes and the amount so expended
(including reasonable attorney's fees and expenses, filing fees and other
charges) shall be payable by Borrowers on demand and shall constitute part of
the Bank Indebtedness.



                                       35
<PAGE>

         With respect to any amount required to be paid by Borrowers under this
Section, in the event Borrowers fail to pay such amount on demand, Borrowers
shall also pay to Bank interest thereon at the default rate set forth in SECTION
3.10.

         Each Borrower agrees to indemnify and hold harmless, Bank and Bank's
officers, directors, shareholders, employees and agents, from and against any
and all claims, liabilities, losses, damages, costs and expenses (whether or not
such Person is a party to any litigation), including reasonable attorney's fees
and costs and costs of investigation, document production, attendance at
depositions or other discovery with respect to or arising out of this Agreement,
the use of any proceeds advanced hereunder, the transactions contemplated
hereunder, or any claim, demand, action or cause of action being asserted
against either Borrower or any of its Affiliates unless caused by the gross
negligence or willful misconduct of any of the foregoing indemnitees.

         Borrowers' obligations under this Section shall survive termination of
this Agreement and repayment of the Bank Indebtedness.

                  13.10 TIME IS OF THE ESSENCE. Time is of the essence in
Borrowers' performance of their obligations under the Loan Documents.

                  13.11 ACKNOWLEDGEMENT OF CONFESSION OF JUDGMENT PROVISIONS.
BORROWERS ACKNOWLEDGE AND AGREE THAT THE WC LINE NOTE, THE EQUIPMENT LINE NOTE
AND THE LOAN DOCUMENTS CONTAIN PROVISIONS WHEREBY BANK MAY ENTER JUDGMENT BY
CONFESSION AGAINST BORROWERS. BORROWERS BEING FULLY AWARE OF THEIR RIGHTS TO
PRIOR NOTICE AND HEARING ON THE QUESTION OF THE VALIDITY OF ANY CLAIMS THAT MAY
BE ASSERTED AGAINST THEM BY BANK UNDER THE WC LINE NOTE, THE EQUIPMENT LINE
NOTE, AND LOAN DOCUMENTS, BEFORE JUDGMENT CAN BE ENTERED, BORROWERS HEREBY WAIVE
THESE RIGHTS AND AGREE AND CONSENT TO BANK ENTERING JUDGMENT AGAINST EACH
BORROWER BY CONFESSION. ANY PROVISION IN A CONFESSION OF JUDGMENT IN ANY OF THE
LOAN DOCUMENTS FOR AN ATTORNEY'S COLLECTION COMMISSION SHALL IN NO WAY LIMIT ANY
BORROWER'S LIABILITY TO REIMBURSE BANK (WITHOUT DUPLICATION) FOR ALL LEGAL FEES
ACTUALLY INCURRED BY BANK, EVEN IF SUCH FEES ARE IN EXCESS OF THE ATTORNEY'S
COLLECTION COMMISSION PROVIDED FOR IN SUCH CONFESSION OF JUDGMENT.

         14. COMMUNICATIONS AND NOTICES.

                  14.1 COMMUNICATIONS AND NOTICES. All notices, requests and
other communications made or given in connection with the Loan Documents shall

PROCEEDINGS;

                            (b) ALL BENEFITS UNDER ANY PRESENT OR FUTURE LAWS
EXEMPTING ANY PROPERTY, REAL OR PERSONAL, OR ANY PART OF ANY PROCEEDS THEREOF
FROM ATTACHMENT, LEVY OR SALE UNDER EXECUTION, OR PROVIDING FOR ANY STAY OF

                  15.2 FORBEARANCE. Bank may release, compromise, forbear with
respect to, waive, suspend, extend or renew any of the terms of the Loan
Documents, without notice to any Borrower.

                  15.3 LIMITATION ON LIABILITY. Subject to the obligation of the
Bank to act in a commercially reasonable manner, each Borrower shall be
responsible for and Bank is hereby released from any claim or liability in
connection with:

                            (a) Safekeeping any Collateral;

                            (b) Any loss or damage to any Collateral;

<PAGE>

         Bank shall only be liable for any act or omission on its part
constituting willful misconduct or gross negligence. In the event that Bank
breaches its required standard of conduct, each Borrower agrees that its
liability shall be only for direct damages suffered and shall not extend to
consequential or incidental damages. In the event any Borrower brings suit
against Bank in connection with the transactions contemplated hereunder and Bank
is found not to be liable, Borrowers will indemnify and hold Bank harmless from
all costs and expenses, including attorney's fees, incurred by Bank in
connection with such suit. This Agreement is not intended to obligate Bank to
take any action with respect to the Collateral or to incur expenses or perform
any obligation or duty of Borrowers, subject to the obligation of Bank to act in
a commercially reasonable manner.

         16. SUBMISSION TO JURISDICTION.

                  16.1 SUBMISSION TO JURISDICTION. Each Borrower hereby consents
to the exclusive jurisdiction of any state or federal court located within the
Commonwealth of Pennsylvania, and irrevocably agrees that all actions or
proceedings relating to the Loan Documents or the transactions contemplated
hereunder shall be litigated in such courts, and each Borrower waives any
objection which it may have based on lack of personal jurisdiction, improper
venue or forum non conveniens to the conduct of any proceeding in any such court
and waives personal service of any and all process upon it, and consents that
all such service of process be made by mail or messenger directed to it at the
address set forth in SECTION 14.1. Nothing contained in this SECTION 16.1 shall
affect the right of Bank to serve legal process in any other manner permitted by
law or affect the right of Bank to bring any action or proceeding against any
Borrower or their property in the courts of any other jurisdiction.

         17. AMENDMENTS. In the event Bank becomes a lender and Administrative
Agent under the Credit Agreement and, thereafter, one or more affirmative
covenants, negative covenants or financial covenants in the Credit Agreement are
amended and Bank was one of the lenders voting in favor of such amendment, Bank
and Borrowers agree that, provided no Default or Event of Default shall have
occurred and be continuing, Bank and Borrowers will enter into an amendment to
this Agreement in form and content reasonably satisfactory to Bank, amending one
or more of the covenants in this Agreement to the extent necessary to be
consistent with the covenant under the Credit Agreement, as amended.

         18. MISCELLANEOUS.

                  18.1 BROKERS. The transaction contemplated hereunder was
brought about and entered into by Bank and Borrowers acting as principals and
without any brokers, agents or finders being the effective procuring cause
hereof. Each Borrower represents to Bank that no Borrower has committed Bank to
the payment of any brokerage fee or commission in connection with this
transaction. If any such claim is made against either party by any broker,
finder or agent or any other Person based upon the other party's conduct, the
other party agrees to indemnify, defend and hold the first party harmless
against any such claim, at the indemnity party's own cost and expense, including
the other party's reasonable attorneys' fees. Borrowers further agree that until
any such claim or demand against Bank is adjudicated in Bank's favor, the amount
claimed and/or demanded shall be deemed part of the Bank Indebtedness secured by
the Collateral.

                  18.2 USE OF BANK'S NAME. No Borrower shall use Bank's name or
the name of any of Bank's Affiliates in connection with any of its business or
activities except as may otherwise be required by the rules and regulations of
the Securities and Exchange Commission or any like regulatory body and except as
may be required in its dealings with any governmental agency.

                  18.3 NO JOINT VENTURE. Nothing contained herein is intended to
permit or authorize any Borrower to make any contract on behalf of Bank, nor
shall this Agreement be construed as creating a partnership or joint venture or
making Bank an investor in any Borrower.

                  18.4 JOINT AND SEVERAL LIABILITY. All agreements, conditions,
covenants and provisions of the Loan Documents shall be the joint and several
obligation of each Borrower.

                  18.5 SURVIVAL. All covenants and agreements made by Borrowers
in the Loan Documents or made by or on their behalf in connection with the
transactions contemplated here shall be true at all times this Agreement is in
effect and shall survive the execution and delivery of the Loan Documents, any
investigation at any time made by Bank or on its behalf and the making by Bank
of the loans or advances to Borrowers. All statements contained in any
certificate, statement or other document delivered by or on behalf of any
Borrower pursuant hereto or in connection with the


                                       38
<PAGE>

transactions contemplated hereunder shall be deemed representations and
warranties by Borrowers. All representations and warranties made by Borrowers in
the Loan Documents or made by or on their behalf in connection with the
transactions contemplated here shall be true and correct when made.

                  18.6 NO ASSIGNMENT BY BORROWERS. Borrowers may not assign any
of their rights hereunder without the prior written consent of Bank, and Bank
shall not be required to lend hereunder except to Borrowers as they presently
exist, except for changes not prohibited by this Agreement.

                  18.7 ASSIGNMENT OR SALE BY BANK. Bank may sell, assign or
participate to an institutional lender all or a portion of its interest in the
Loan Documents and in connection therewith may make available to any prospective
purchaser, assignee or participant any information relative to Borrowers in its
possession, but only under circumstances reasonably designed to ensure the
preservation of the confidentiality of all non-public and other confidential
information.

                  18.8 BINDING EFFECT. This Agreement and all rights and powers
granted hereby will bind and inure to the benefit of the parties hereto and
their respective permitted successors and assigns.

                  18.9 SEVERABILITY. The provisions of this Agreement and all
other Loan Documents are deemed to be severable, and the invalidity or
unenforceability of any provision shall not affect or impair the remaining
provisions which shall continue in full force and effect.

                  18.10 NO THIRD PARTY BENEFICIARIES. The rights and benefits of
this Agreement and the Loan Documents shall not inure to the benefit of any
third party.

                  18.11 MODIFICATIONS. No modification of this Agreement or any
of the Loan Documents shall be binding or enforceable unless in writing and
signed by or on behalf of the party against whom enforcement is sought.

                  18.12 HOLIDAYS. If the day provided herein for the payment of
any amount or the taking of any action falls on a Saturday, Sunday or public
holiday at the place for payment or action, then the due date for such payment
or action will be the next succeeding Business Day.

                  18.13 LAW GOVERNING. This Agreement has been made, executed
and delivered in the Commonwealth of Pennsylvania and will be construed in
accordance with and governed by the laws of such Commonwealth.

                  18.14 INTEGRATION. The Loan Documents shall be construed as
integrated and complementary of each other, and as augmenting and not
restricting Bank's rights, powers, remedies and security. The Loan Documents
contain the entire understanding of the parties thereto with respect to the
matters contained therein and supersede all prior agreements and understandings
between the parties with respect to the subject matter thereof and do not
require parole or extrinsic evidence in order to reflect the intent of the
parties. In the event of any inconsistency between the terms of this Agreement
and the terms of the other Loan Documents, the terms of this Agreement shall
prevail.

                  18.15 EXHIBITS AND SCHEDULES. All exhibits and schedules
attached hereto are hereby made a part of this Agreement.

                  18.16 HEADINGS. The headings of the Articles, Sections,
paragraphs and clauses of this Agreement are inserted for convenience only and
shall not be deemed to constitute a part of this Agreement.

                  18.17 COUNTERPARTS. This Agreement may be executed in any
