         discretion) after the date of the invoice and does not remain unpaid
         ninety (90) days past the invoice date thereof (or one hundred twenty
         (120) days with respect to Accounts acceptable to Lender in its sole
         discretion); provided, however, that if more than twenty-five percent
         (25%) of the aggregate dollar amount of invoices owing by a particular
         Account Debtor remain unpaid ninety (90) days (or one hundred twenty
         (120) days with respect to Accounts acceptable to Lender in its sole
         discretion) after the respective invoice dates thereof, then all
         Accounts owing by that Account Debtor shall be deemed ineligible;

                  (v) it is a valid, legally enforceable and unconditional
         obligation of the Account Debtor thereunder, and it shall not be an
         Eligible Account to the extent of any setoff, counterclaim, credit,
         allowance or adjustment by such Account Debtor, or if it is subject to
         any claim by such Account Debtor denying liability thereunder in whole
         or in part;

                  (vi) it does not arise out of a contract or order which fails

         law;

                  (vii) the Account Debtor thereunder is not a director,
         officer, employee or agent of a Borrower, or a Subsidiary, Parent or
         Affiliate;

                  (viii) it is not an Account with respect to which the Account
         Debtor is the United States of America or any state or local
         government, or any department, agency or instrumentality thereof,
         unless such Borrower assigns its right to payment of such Account to
         Lender pursuant to, and in full compliance with, the Assignment of
         Claims Act of 1940, as amended, or any comparable state or local law,
         as applicable;

                  (ix) it is not an Account with respect to which the Account
         Debtor is located in a state which requires such Borrower, as a
         precondition to commencing or maintaining an action in the courts of
         that state, either to (A) receive a certificate of authority to do
         business and be in good standing in such state; or (B) file a notice of
         business activities report or similar report with such state's taxing
         authority, unless (x) such Borrower has taken one of the actions
         described in clauses (A) or (B); (y) the failure to take one of the
         actions described in either clause (A) or (B) may be cured
         retroactively by such Borrower at its election; or (z) such Borrower
         has proven, to Lender's satisfaction, that it is exempt from any such
         requirements under any such state's laws;

                  (x) the Account Debtor is located within the United States of
         America or Canada;

                                      -4-


                  (xi) it is not an Account with respect to which the Account
         Debtor's obligation to pay is subject to any repurchase obligation or
         return right, as with sales made on a bill-and-hold, guaranteed sale,
         sale on approval, sale or return or consignment basis;

                  (xii) it is not an Account (A) with respect to which any
         representation or warranty contained in this Agreement is untrue; or
         (B) which violates any of the covenants of such Borrower contained in
         this Agreement;

sole discretion, determined in good faith, make revolving loans and advances to
each Borrower (the "REVOLVING LOANS") in an amount up to the sum of the
following sublimits (the "REVOLVING LOAN LIMIT"):

                  (i) Up to eighty-five percent (85%) of the face amount (less
         maximum discounts, credits and allowances which may be taken by or
         granted to Account Debtors in connection therewith in the ordinary
         course of such Borrower's business) of such Borrower's Eligible
         Accounts; plus

                  (ii) Up to thirty percent (30%) of the lower of cost or market

         finished goods; minus

                  (iv) such reserves as Lender elects, in its sole discretion
         determined in good faith, to establish from time to time, including,
         without limitation a reserve of Five Hundred Thousand and No/100
         Dollars ($500,000.00) which shall be released within five (5) Business
         Days of receipt of Borrowers' certified 2004 Fiscal Year end financial
         statements so long as such financial statements reflect a ratio of
         EBITDA to Fixed Charges of not less than 1.15:1.00 and no Event of
         Default has occurred;

provided, that (x) the sum of the advances to all Borrowers with respect to
clauses (ii) and (iii) above shall at no time exceed Three Million Five Hundred
Thousand and No/100 Dollars ($3,500,000.00) and (y) the Revolving Loan Limit
shall in no event exceed Ten Million and No/100 Dollars ($10,000,000.00) less
the then-outstanding principal balance of the Term Loan (the "MAXIMUM REVOLVING
LOAN LIMIT") except as such amount may be increased or decreased by Lender, in
its sole discretion.

         The aggregate unpaid principal balance of the Revolving Loans shall not
at any time exceed the lesser of the (i) Revolving Loan Limit minus the Letter
of Credit

                                      -10-


Obligations and (ii) the Maximum Revolving Loan Limit minus the Letter of Credit
Obligations. If at any time the outstanding Revolving Loans exceeds either the
Revolving Loan Limit or the Maximum Revolving Loan Limit, in each case minus the
Letter of Credit Obligations, or any portion of the Revolving Loans and Letter
of Credit Obligations exceeds any applicable sublimit within the Revolving Loan
Limit, Borrowers shall immediately, and without the necessity of demand by
Lender, pay to Lender such amount as may be necessary to eliminate such excess
and Lender shall apply such payment to the Revolving Loans to eliminate such
excess.

         Each Borrower hereby authorizes Lender, in its sole discretion, to
charge any of such Borrower's accounts or advance Revolving Loans to make any
payments of principal, interest, fees, costs or expenses required to be made
under this Agreement or the Other Agreements.

         A request for a Revolving Loan shall be made or shall be deemed to be
made, each in the following manner: the Borrower requesting such Revolving Loan
shall give Lender same day notice, no later than 1:00 P.M. (determined based on
the local time of each Borrower at its principal place of business) for such
day, of its request for a Revolving Loan as a Prime Rate Loan. In the event that
a Borrower maintains a controlled disbursement account at LaSalle Bank, each
check presented for payment against such controlled disbursement account and any
other charge or request for payment against such controlled disbursement account
shall constitute a request for a Revolving Loan as a Prime Rate Loan. As an
accommodation to Borrowers, Lender may permit telephone requests for Revolving
Loans and electronic transmittal of instructions, authorizations, agreements or
reports to Lender by Borrowers. Unless a Borrower specifically directs Lender in
writing not to accept or act upon telephonic or electronic communications from
such Borrower, Lender shall have no liability to Borrowers for any loss or
damage suffered by a Borrower as a result of Lender's honoring of any requests,
execution of any instructions, authorizations or agreements or reliance on any
reports communicated to it telephonically or electronically and purporting to
have been sent to Lender by a Borrower and Lender shall have no duty to verify
the origin of any such communication or the authority of the Person sending it.

         Each Borrower hereby irrevocably authorizes Lender to disburse the
proceeds of each Revolving Loan requested by such Borrower, or deemed to be
requested by such Borrower, as follows: the proceeds of each Revolving Loan
requested under Section 2(a) shall be disbursed by Lender in lawful money of the
United States of America in immediately available funds, in the case of the
initial borrowing, in accordance with the terms of the written disbursement
letter from such Borrower, and in the case of each subsequent borrowing, by wire
transfer or Automated Clearing House (ACH) transfer to such bank account as may
be agreed upon by such Borrower and Lender from time to time, or elsewhere if
pursuant to a written direction from such Borrower.

                                      -11-


         (b) CAPITAL EXPENDITURE LOANS.

         Subject to the terms and conditions of this Agreement and the Other
Agreements, from time to time after the initial Loans are advanced hereunder,
Lender shall make advances to each Borrower up to eighty percent (80%) of the
purchase price (exclusive of sales taxes, delivery charges and other "soft"
costs related to such purchase) of Equipment to be purchased with the proceeds
of such advances, which Equipment is acceptable to Lender in its sole
discretion, and upon which Lender shall have a first priority perfected security
interest; provided, that (i) the aggregate amount advanced for such purchases
shall not exceed Five Hundred Thousand and No/100 Dollars ($500,000.00), (ii) at
least three (3) Business Days prior to any such advance hereunder, such Borrower
shall have furnished to Lender an invoice and acceptance letter for the
Equipment being purchased and shall have executed such documents and taken such
other actions as Lender shall require to assure that Lender has a first priority
perfected security interest in such Equipment, and (iii) each advance hereunder
shall be in an amount not less than Fifty Thousand and No/100 Dollars
($50,000.00). Amounts repaid with respect to the Capital Expenditure Loans may
not be reborrowed.

         (c) REPAYMENTS.

         The Liabilities shall be repaid as follows:

                  (i) Repayment of Revolving Loans. The Revolving Loans and all
         other Liabilities (other than the Term Loan) shall be repaid on the
         last day of the Original Term or any Renewal Term if this Agreement is
         renewed pursuant to Section 10 hereof.

                  (ii) Repayment of Capital Expenditure Loans. Each Capital
         Expenditure Loan shall be repaid in forty-eight (48) equal monthly
         installments in an amount sufficient to repay such Capital Expenditure
         Loan in full by the final payment. Such payments shall be made on the
         thirtieth (30th) day following the date of each such advance, and on
         the corresponding day of each month thereafter; provided, that any
         remaining outstanding principal balance of the Capital Expenditures
         Loan shall be repaid at the end of the Original Term or any Renewal
         Term if this Agreement is renewed pursuant to Section 10 hereof. If any
         such payment due date is not a Business Day, then such payment may be
         made on the next succeeding Business Day and such extension of time
         shall be included in the computation of the amount of interest and fees
         due hereunder.

                  (iii) Mandatory Prepayments of the Term Loan.

                           (a) Sales of Assets. Upon receipt of the proceeds of
                  the sale or other disposition of any Equipment or real
                  property of a Borrower which is subject to a mortgage in favor
                  of Lender, or if any of the Equipment or real

                                      -12-


                  property subject to such mortgage is damaged, destroyed or
                  taken by condemnation in whole or in part, the proceeds
                  thereof shall be paid by such Borrower to Lender as a
                  mandatory prepayment of the Capital Expenditure Loan which was
                  advanced against the value of such asset, such payment to be
                  applied against the remaining installments of principal in the
                  inverse order of their maturities until such Capital
                  Expenditure Loan is repaid in full, and then against the other
                  Liabilities, as determined by Lender, in its sole discretion.

         (d) NOTES.

         The Loans shall, in Lender's sole discretion, be evidenced by one or
more promissory notes in form and substance satisfactory to Lender. However, if
such Loans are not so evidenced, such Loans may be evidenced solely by entries
upon the books and records maintained by Lender.

         3. LETTERS OF CREDIT.

         (a) GENERAL TERMS.

         Subject to the terms and conditions of this Agreement and the Other
Agreements, during the Original Term or any Renewal Term, Lender may, in its
sole discretion, from time to time cause to be issued and co-sign for or
otherwise guarantee, upon a Borrower's request, commercial and/or standby
Letters of Credit; provided, that the aggregate undrawn face amount of all such
Letters of Credit shall at no time exceed Two Million and No/100 Dollars
($2,000,000.00). Payments made by the issuer of a Letter of Credit to any Person
on account of any Letter of Credit shall be immediately payable by Borrowers
without notice, presentment or demand and each Borrower agrees that each payment
made by the issuer of a Letter of Credit in respect of a Letter of Credit shall
constitute a request by each Borrower for a Loan to reimburse such issuer. In
the event such Loan is not advanced by Lender for any reason, such reimbursement
obligations (whether owing to the issuer of the Letter of Credit or Lender if
Lender is not the issuer) shall become part of the Liabilities hereunder and
shall bear interest at the rate then applicable to Revolving Loans constituting
Prime Rate Loans until repaid. Borrowers shall remit to Lender a Letter of
Credit fee equal to two and one-half percent (2-1/2%) per annum on the aggregate
undrawn face amount of all Letters of Credit outstanding, which fee shall be
payable monthly in arrears on the last Business Day of each month. Borrowers
shall also pay on demand the normal and customary administrative charges of the
issuer of the Letter of Credit for issuance, amendment, negotiation, renewal or
extension of any Letter of Credit.

         (b) REQUESTS FOR LETTERS OF CREDIT.

         Each Borrower shall make requests for Letters of Credit in writing at
least two (2) Business Days prior to the date such Letter of Credit is to be
issued. Each such request shall specify the date such Letter of Credit is to be
issued, the amount thereof, the name and


                                      -13-


address of the beneficiary thereof and a description of the transaction to be
supported thereby. Any such notice shall be accompanied by the form of Letter of
Credit requested and any application or reimbursement agreement required by the
issuer of such Letter of Credit. If any term of such application or
reimbursement agreement is inconsistent with this Agreement, then the provisions
of this Agreement shall control to the extent of such inconsistency.

         (c) OBLIGATIONS ABSOLUTE.

         Each Borrower shall be obligated to reimburse the issuer of any Letter
of Credit, or Lender if Lender has reimbursed such issuer on a Borrower's
behalf, for any payments made in respect of any Letter of Credit, which
obligation shall be unconditional and irrevocable and shall be paid regardless
of: (i) any lack of validity or enforceability of any Letter of Credit, (ii) any
amendment or waiver of or consent or departure from all or any provisions of any
Letter of Credit, this Agreement or any Other Agreement, (iii) the existence of
any claim, set off, defense or other right which a Borrower or any other Person
may have against any beneficiary of any Letter of Credit, Lender or the issuer
of the Letter of Credit, (iv) any draft or other document presented under any
Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect,
(v) any payment under any Letter of Credit against presentation of a draft or
other document that does not comply with the terms of such Letter of Credit, and
(vi) any other act or omission to act or delay of any kind of the issuer of such
Letter of Credit, the Lender or any other Person or any other event or
circumstance that might otherwise constitute a legal or equitable discharge of a
Borrower's obligations hereunder. It is understood and agreed by each Borrower
that the issuer of any Letter of Credit may accept documents that appear on
their face to be in order without further investigation or inquiry, regardless
of any notice or information to the contrary.

         (d) EXPIRATION DATES OF LETTERS OF CREDIT.

         The expiration date of each Letter of Credit shall be no later than the
earlier of (i) one (1) year from the date of issuance and (ii) the thirtieth
(30th) day prior to the end of the Original Term or any Renewal Term.
Notwithstanding the foregoing, a Letter of Credit may provide for automatic
extensions of its expiration date for one or more one (1) year periods, so long
as the issuer thereof has the right to terminate the Letter of Credit at the end
of each one (1) year period and no extension period extends past the thirtieth
(30th) day prior to the end of the Original Term or any Renewal Term.

         4. INTEREST, FEES AND CHARGES.

         (a) INTEREST RATE.

         Each Loan shall bear interest at the rate of one percent (1%) per annum
in excess of the Prime Rate in effect from time to time, payable on the last
Business Day of each

                                      -14-


month in arrears. Said rate of interest shall increase or decrease by an amount
equal to each increase or decrease in the Prime Rate effective on the effective
date of each such change in the Prime Rate. Upon the occurrence of an Event of
Default and during the continuance thereof, each Loan shall bear interest at the
rate of two percent (2%) per annum in excess of the interest rate otherwise
payable thereon, which interest shall be payable on demand. All interest shall
be calculated on the basis of a 360-day year.

         (b) FEES AND CHARGES.

                  (i) Closing Fee: Borrowers shall jointly and severally pay to
         Lender a closing fee of One Hundred Thousand and No/100 Dollars
         ($100,000.00), which fee shall be fully earned and payable on the date
         of disbursement of the initial Loans hereunder.

                  (ii) Unused Line Fee: Borrowers shall jointly and severally
         pay to Lender an unused line fee of one-half of one percent (1/2 of 1%)
         of the difference between the Maximum Revolving Loan Limit and the
         average daily balance of the Revolving Loans plus the Letter of Credit
         Obligations for each month, which fee shall be fully earned by Lender
         and payable monthly in arrears on the first Business Day of each month.
         Said fee shall be calculated on the basis of a 360 day year.

                  (iii) Transaction Fee: Borrowers shall jointly and severally
         pay to Lender a transaction fee of Twenty Thousand and No/100 Dollars
         ($20,000.00) with respect to internal costs and expenses (in addition
         to any reimbursable out-of-pocket costs and expenses of Lender) related
         to the closing of the loan transaction contemplated hereby, which fee
         shall be fully earned and payable on the date that Lender makes its
         initial disbursement of Loans hereunder.

                  (iv) Costs and Expenses: Borrowers shall jointly and severally
         reimburse Lender for all costs and expenses, including, without
         limitation, legal expenses and reasonable attorneys' fees (whether for
         internal or outside counsel), incurred by Lender in connection with the
         (i) documentation and consummation of this transaction and any other
         transactions between Borrowers and Lender, including, without
         limitation, Uniform Commercial Code and other public record searches
         and filings, overnight courier or other express or messenger delivery,
         appraisal costs, surveys, title insurance and environmental audit or
         review costs; (ii) collection, protection or enforcement of any rights
         in or to the Collateral; (iii) collection of any Liabilities; and (iv)
         administration and enforcement of any of Lender's rights under this
         Agreement or any Other Agreement. Borrowers shall also pay all normal
         service charges with respect to all accounts maintained by each
         Borrower with Lender and LaSalle Bank and any additional services
         requested by a Borrower from Lender and LaSalle Bank. All such costs,
         expenses and charges shall, if owed to LaSalle Bank, be reimbursed by
         Lender and in such event or in the event such costs and expenses are
         owed to Lender, shall constitute Liabilities hereunder, shall be
         payable by Borrowers

                                      -15-


         to Lender on demand, and, until paid, shall bear interest at the
         highest rate then applicable to Loans hereunder.

                  (v) Capital Adequacy Charge. If Lender shall have determined
         that the adoption of any law, rule or regulation regarding capital
         adequacy, or any change therein or in the interpretation or application
         thereof, or compliance by Lender with any request or directive
         regarding capital adequacy (whether or not having the force of law)
         from any central bank or governmental authority enacted after the date
         hereof, does or shall have the effect of reducing the rate of return on
         such party's capital as a consequence of its obligations hereunder to a
         level below that which Lender could have achieved but for such
         adoption, change or compliance (taking into consideration Lender's
         policies with respect to capital adequacy) by a material amount, then
         from time to time, after submission by Lender to Borrowers of a written
         demand therefor ("CAPITAL ADEQUACY DEMAND") together with the
         certificate described below, Borrowers shall pay to Lender such
         additional amount or amounts ("CAPITAL ADEQUACY CHARGE") as will
         compensate Lender for such reduction, such Capital Adequacy Demand to
         be made with reasonable promptness following such determination. A
         certificate of Lender claiming entitlement to payment as set forth
         above shall be conclusive in the absence of manifest error. Such
         certificate shall set forth the nature of the occurrence giving rise to
         such reduction, the amount of the Capital Adequacy Charge to be paid to
         Lender, and the method by which such amount was determined. In
         determining such amount, Lender may use any reasonable averaging and
         attribution method, applied on a non-discriminatory basis.

         (c) MAXIMUM INTEREST.

         It is the intent of the parties that the rate of interest and other
charges to each Borrower under this Agreement and the Other Agreements shall be
lawful; therefore, if for any reason the interest or other charges payable under
this Agreement are found by a court of competent jurisdiction, in a final
determination, to exceed the limit which Lender may lawfully charge such
Borrower, then the obligation to pay interest and other charges shall
automatically be reduced to such limit and, if any amount in excess of such
limit shall have been paid, then such amount shall be refunded to such Borrower.

         5. COLLATERAL.

         (a) GRANT OF SECURITY INTEREST TO LENDER.

         As security for the payment of all Loans now or in the future made by
Lender to Borrowers hereunder and for the payment or other satisfaction of all
other Liabilities, each Borrower hereby assigns to Lender and grants to Lender a
continuing security interest in the following property of such Borrower, whether
now or hereafter owned, existing, acquired or arising and wherever now or
hereafter located: (a) all Accounts (whether or not Eligible Accounts) and all
Goods whose sale, lease or other disposition by such Borrower has given

                                      -16-


rise to Accounts and have been returned to, or repossessed or stopped in transit
by, such Borrower; (b) all Chattel Paper, Instruments, Documents and General
Intangibles (including, without limitation, all patents, patent applications,
trademarks, trademark applications, trade names, trade secrets, goodwill,
copyrights, copyright applications, registrations, licenses, software,
franchises, customer lists, tax refund claims, claims against carriers and
shippers, guarantee claims, contract rights, payment intangibles, security
interests, security deposits and rights to indemnification); (c) all Inventory
(whether or not Eligible Inventory); (d) all Goods (other than Inventory),
including, without limitation, Equipment, vehicles and Fixtures; (e) all
Investment Property; (f) all Deposit Accounts, bank accounts, deposits and cash;
(g) all Letter-of-Credit Rights; (h) Commercial Tort Claims listed on Exhibit C

purpose (whether for safekeeping, deposit, collection, custody, pledge,
transmission or otherwise) and (j) all additions and accessions to,
substitutions for, and replacements, products and Proceeds of the foregoing
property, including, without limitation, proceeds of all insurance policies
insuring the foregoing property, and all of such Borrower's books and records
relating to any of the foregoing and to such Borrower's business.

         (b) OTHER SECURITY.

         Lender, in its sole discretion, without waiving or releasing any
obligation, liability or duty of a Borrower under this Agreement or the Other
Agreements or any Event of Default, may at any time or times hereafter, but
shall not be obligated to, pay, acquire or accept an assignment of any security
interest, lien, encumbrance or claim asserted by any Person in, upon or against
the Collateral, provided, that Lender may take such actions with respect to
Permitted Liens only after the occurrence and during the continuance of an Event
of Default. All sums paid by Lender in respect thereof and all costs, fees and
expenses including, without limitation, reasonable attorney fees, all court
costs and all other charges relating thereto incurred by Lender shall constitute
Liabilities, payable by Borrowers to Lender on demand and, until paid, shall
bear interest at the highest rate then applicable to Loans hereunder.

         (c) POSSESSORY COLLATERAL.

         Immediately upon a Borrower's receipt of any portion of the Collateral
evidenced by an agreement, Instrument or Document, including, without
limitation, any Tangible Chattel Paper and any Investment Property consisting of
certificated securities, such Borrower shall deliver the original thereof to
Lender together with an appropriate endorsement or other specific evidence of
assignment thereof to Lender (in form and substance acceptable to Lender). If an
endorsement or assignment of any such items shall not be made for any reason,
Lender is hereby irrevocably authorized, as each Borrower's attorney and
agent-in-fact, to endorse or assign the same on such Borrower's behalf.

                                      -17-


         (d) ELECTRONIC CHATTEL PAPER.

         To the extent that a Borrower obtains or maintains any Electronic
Chattel Paper, such Borrower shall create, store and assign the record or
records comprising the Electronic Chattel Paper in such a manner that (i) a
single authoritative copy of the record or records exists which is unique,
identifiable and except as otherwise provided in clauses (iv), (v) and (vi)
below, unalterable, (ii) the authoritative copy identifies Lender as the
assignee of the record or records, (iii) the authoritative copy is communicated
to and maintained by the Lender or its designated custodian, (iv) copies or
revisions that add or change an identified assignee of the authoritative copy
can only be made with the participation of Lender, (v) each copy of the
authoritative copy and any copy of a copy is readily identifiable as a copy that
is not the authoritative copy and (vi) any revision of the authoritative copy is
readily identifiable as an authorized or unauthorized revision.

         6. PRESERVATION OF COLLATERAL AND PERFECTION OF SECURITY INTERESTS
THEREIN.

         Each Borrower shall, at Lender's request, at any time and from time to
time, authenticate, execute and deliver to Lender such financing statements,
documents and other agreements and instruments (and pay the cost of filing or
recording the same in all public offices deemed necessary or desirable by
Lender) and do such other acts and things or cause third parties to do such
other acts and things as Lender may deem necessary or desirable in its sole
discretion in order to establish and maintain a valid, attached and perfected
security interest in the Collateral in favor of Lender (free and clear of all
other liens, claims, encumbrances and rights of third parties whatsoever,
whether voluntarily or involuntarily created, except Permitted Liens) to secure
payment of the Liabilities, and in order to facilitate the collection of the
Collateral. Each Borrower irrevocably hereby makes, constitutes and appoints
Lender (and all Persons designated by Lender for that purpose) as such
Borrower's true and lawful attorney and agent-in-fact to execute and file such
financing statements, documents and other agreements and instruments and do such
other acts and things as may be necessary to preserve and perfect Lender's
security interest in the Collateral. Each Borrower further agrees that a carbon,
photographic, photostatic or other reproduction of this Agreement or of a
financing statement shall be sufficient as a financing statement. Each Borrower
further ratifies and confirms the prior filing by Lender of any and all
financing statements which identify such Borrower as debtor, Lender as secured
party and any or all Collateral as collateral.

         7. POSSESSION OF COLLATERAL AND RELATED MATTERS.

         Until otherwise notified by Lender following the occurrence of an Event
of Default, each Borrower shall have the right, except as otherwise provided in
this Agreement, in the ordinary course of such Borrower's business, to (a) sell,
lease or furnish under contracts of service any of such Borrower's Inventory
normally held by such Borrower for any such purpose; (b) use and consume any raw
materials, work in process or other materials normally


                                      -18-


held by such Borrower for such purpose; and (c) dispose of obsolete or unuseful
Equipment so long as all of the proceeds thereof are paid to Lender for
application to the Liabilities (except for such proceeds which are required to
be delivered to the holder of a Permitted Lien which is prior in right of
payment); provided, however, that a sale in the ordinary course of business
shall not include any transfer or sale in satisfaction, partial or complete, of
a debt owed by such Borrower.

         8. COLLECTIONS.

         (a) Each Borrower shall direct all of its Account Debtors to make all
payments on the Accounts directly to a post office box (the "LOCK BOX")
designated by, and under the exclusive control of, Lender, at a financial
institution acceptable to Lender. Each Borrower shall establish an account (the
"LOCK BOX ACCOUNT") in Lender's name with a financial institution acceptable to
Lender, into which all payments received in the Lock Box shall be deposited, and
into which such Borrower will immediately deposit all payments received by such
Borrower on Accounts in the identical form in which such payments were received,
whether by cash or check. If a Borrower, any Affiliate or Subsidiary, any
shareholder, officer, director, employee or agent of a Borrower or any Affiliate
or Subsidiary, or any other Person acting for or in concert with a Borrower
shall receive any monies, checks, notes, drafts or other payments relating to or
as Proceeds of Accounts or other Collateral, such Borrower and each such Person
shall receive all such items in trust for, and as the sole and exclusive
property of, Lender and, immediately upon receipt thereof, shall remit the same
(or cause the same to be remitted) in kind to the Lock Box Account. The
financial institution with which the Lock Box Account is established shall
acknowledge and agree, in a manner satisfactory to Lender, that the amounts on
deposit in such Lock Box and Lock Box Account are the sole and exclusive
property of Lender, that such financial institution will follow the instructions
of Lender with respect to disposition of funds in the Lock Box and Lock Box
Account without further consent from Borrowers, that such financial institution
has no right to setoff against the Lock Box or Lock Box Account or against any
other account maintained by such financial institution into which the contents
of the Lock Box or Lock Box Account are transferred, and that such financial
institution shall wire, or otherwise transfer in immediately available funds to
Lender in a manner satisfactory to Lender, funds deposited in the Lock Box
Account on a daily basis as such funds are collected. Each Borrower agrees that
all payments made to such Lock Box Account or otherwise received by Lender,
whether in respect of the Accounts or as Proceeds of other Collateral or
otherwise (except for proceeds of Collateral which are required to be delivered
to the holder of a Permitted Lien which is prior in right of payment), will be
applied on account of the Liabilities in accordance with the terms of this
Agreement. Each Borrower agrees to pay all customary fees, costs and expenses in
connection with opening and maintaining the Lock Box and Lock Box Account. All
of such fees, costs and expenses if not paid by a Borrower, may be paid by
Lender and in such event all amounts paid by Lender shall constitute Liabilities
hereunder, shall be payable to Lender by Borrowers upon demand, and, until paid,
shall bear interest at the highest rate then applicable to Loans hereunder. All
checks, drafts, instruments and other items of


                                      -19-


payment or Proceeds of Collateral shall be endorsed by the applicable Borrower
to Lender, and, if that endorsement of any such item shall not be made for any
reason, Lender is hereby irrevocably authorized to endorse the same on such
Borrower's behalf. For the purpose of this section, each Borrower irrevocably
hereby makes, constitutes and appoints Lender (and all Persons designated by
Lender for that purpose) as such Borrower's true and lawful attorney and
agent-in-fact (i) to endorse such Borrower's name upon said items of payment
and/or Proceeds of Collateral and upon any Chattel Paper, Document, Instrument,
invoice or similar document or agreement relating to any Account of such
Borrower or Goods pertaining thereto; (ii) to take control in any manner of any
item of payment or Proceeds thereof and (iii) to have access to any lock box or
postal box into which any of such Borrower's mail is deposited, and open and
process all mail addressed to such Borrower and deposited therein.

         (b) Lender may, at any time and from time to time after the occurrence
of an Event of Default, whether before or after notification to any Account
Debtor and whether before or after the maturity of any of the Liabilities, (i)
enforce collection of any of Borrowers' Accounts or other amounts owed to a
Borrower by suit or otherwise; (ii) exercise all of such Borrower's rights and
remedies with respect to proceedings brought to collect any Accounts or other
amounts owed to such Borrower; (iii) surrender, release or exchange all or any
part of any Accounts or other amounts owed to such Borrower, or compromise or
extend or renew for any period (whether or not longer than the original period)
any indebtedness thereunder; (iv) sell or assign any Account of such Borrower or
other amount owed to such Borrower upon such terms, for such amount and at such
time or times as Lender deems advisable; (v) prepare, file and sign such
Borrower's name on any proof of claim in bankruptcy or other similar document
against any Account Debtor or other Person obligated to such Borrower; and (vi)
do all other acts and things which are necessary, in Lender's sole discretion,
to fulfill such Borrower's obligations under this Agreement and the Other
Agreements and to allow Lender to collect the Accounts or other amounts owed to
such Borrower. In addition to any other provision hereof, Lender may at any
time, after the occurrence of an Event of Default, at Borrowers' expense, notify
any parties obligated on any of the Accounts to make payment directly to Lender
of any amounts due or to become due thereunder.

         (c) For purposes of calculating interest and fees, Lender shall, within
two (2) Business Days after receipt by Lender at its office in Chicago, Illinois
of (i) checks and (ii) one (1) Business Day after receipt By Lender at its
office in Chicago, Illinois of cash or other immediately available funds from
collections of items of payment and Proceeds of any Collateral, apply the whole
or any part of such collections or Proceeds against the Liabilities in such
order as Lender shall determine in its sole discretion. For purposes of
determining the amount of Loans available for borrowing purposes, checks and
cash or other immediately available funds from collections of items of payment
and Proceeds of any Collateral shall be applied in whole or in part against the
Liabilities, in such order as Lender shall determine in its sole discretion, on
the day of receipt, subject to actual collection.

                                      -20-


         (d) On a monthly basis, Lender shall deliver to Borrowers an account
statement showing all Loans, charges and payments, which shall be deemed final,
binding and conclusive upon Borrowers unless a Borrower notifies Lender in
writing, specifying any error therein, within thirty (30) days of the date such
account statement is sent to Borrowers and any such notice shall only constitute
an objection to the items specifically identified.

         11. REPRESENTATIONS AND WARRANTIES.

         Each Borrower hereby represents and warrants to Lender, which

true until the repayment in full and satisfaction of all the Liabilities and
termination of this Agreement, and shall be remade by each Borrower at the


                                      -23-


time each Loan is made pursuant to this Agreement, provided, that
representations and warranties made as of a particular date shall be true and
correct as of such date.

         (a) FINANCIAL STATEMENTS AND OTHER INFORMATION.

         The financial statements and other information delivered or to be
delivered by Borrowers to Lender at or prior to the date of this Agreement
fairly present in all material respects the financial condition of Borrowers,
and there has been no material adverse change in the financial condition, the
operations or any other status of a Borrower since the date of the financial
statements delivered to Lender most recently prior to the date of this
Agreement. All written information now or heretofore furnished by each Borrower
to Lender is true and correct as of the date with respect to which such
information was furnished.

         (b) LOCATIONS.

                  (r) EMPLOYEE MATTERS.

                  There are no controversies pending or threatened between a
Borrower and any of its employees, agents or independent contractors other than
employee grievances arising in the ordinary course of business which would not,
in the aggregate, have a Material Adverse Effect on such Borrower, and each
Borrower is in compliance with all federal and state laws respecting employment
and employment terms, conditions and practices except for such non-compliance
which would not have a Material Adverse Effect on such Borrower.

                  (s) INTELLECTUAL PROPERTY.

                  12. AFFIRMATIVE COVENANTS.

                  Until payment and satisfaction in full of all Liabilities and
termination of this Agreement, unless Borrowers obtain Lender's prior written
consent waiving or modifying any of Borrowers' covenants hereunder in any
specific instance, each Borrower covenants and agrees as follows:

                  (a) MAINTENANCE OF RECORDS.

                  Each Borrower shall at all times keep accurate and complete
books, records and accounts with respect to all of such Borrower's business
activities, in accordance with sound accounting practices and generally accepted
accounting principles consistently applied, and shall keep such books, records
and accounts, and any copies thereof, only at the addresses indicated for such
purpose on Exhibit A.

                  (b) NOTICES.

                  Each Borrower shall:

                           (i) Locations. Promptly (but in no event less than
         ten (10) days prior to the occurrence thereof) notify Lender of the
         proposed opening of any new place of business or new location of
         Collateral, the closing of any existing place of business or location
         of Collateral, any change of in the location of such Borrower's books,
         records and accounts (or copies thereof), the opening or closing of any
         post office box, the opening or closing of any bank account or, if any
         of the Collateral consists of Goods of a type normally used in more
         than one state, the use of any such Goods in any state other than a
         state in which such Borrower has previously advised Lender that such
         Goods will be used.

                           (ii) Eligible Accounts and Inventory. Promptly upon
         becoming aware thereof, notify Lender if any Account or Inventory
         identified by such Borrower to Lender as an Eligible Account or
         Eligible Inventory becomes ineligible for any reason.

                           (iii) Litigation and Proceedings. Promptly upon
         becoming aware thereof, notify Lender of any actions or proceedings
         which are pending or threatened against such Borrower which might have
         a Material Adverse Effect on such Borrower and of any Commercial Tort
         Claims of such Borrower which may arise, which notice shall constitute
         such Borrower's authorization to amend Exhibit C to add such Commercial
         Tort Claim.

                           (iv) Names and Trade Names. Notify Lender within ten
         (10) days of the change of its name or the use of any trade name,

                                      -29-


                           (v) ERISA Matters. Promptly notify Lender of (x) the
         occurrence of any "reportable event" (as defined in ERISA) which might
         result in the termination by the Pension Benefit Guaranty Corporation
         (the "PBGC") of any employee benefit plan ("Plan") covering any
         officers or employees of such Borrower, any benefits of which are, or
         are required to be, guaranteed by the PBGC, (y) receipt of any notice
         from the PBGC of its intention to seek termination of any Plan or
         appointment of a trustee therefor or (z) its intention to terminate or
         withdraw from any Plan.

                           (vi) Environmental Matters. Immediately notify Lender
         upon becoming aware of any investigation, proceeding, complaint, order,
         directive, claim, citation or notice with respect to any non-compliance
         with or violation of the requirements of any Environmental Law by such
         Borrower or the generation, use, storage, treatment, transportation,
         manufacture handling, production or disposal of any Hazardous Materials
         or any other environmental, health or safety matter which affects such
         Borrower or its business operations or assets or any properties at
         which such Borrower has transported, stored or disposed of any
         Hazardous Materials unless the foregoing could not reasonably be
         expected to have a Material Adverse Effect on such Borrower.

                           (vii) Default; Material Adverse Change. Promptly
         advise Lender of any material adverse change in the business, property,
         assets, prospects, operations or condition, financial or otherwise, of
         such Borrower, the occurrence of any Event of Default hereunder or the
         occurrence of any event which, if uncured, will become an Event of
         Default after notice or lapse of time (or both).

All of the foregoing notices shall be provided by Borrowers to Lender in
writing.

                  (c) COMPLIANCE WITH LAWS AND MAINTENANCE OF PERMITS.

                  Each Borrower shall maintain all governmental consents,
franchises, certificates, licenses, authorizations, approvals and permits, the
lack of which would have a Material Adverse Effect on such Borrower and each
Borrower shall remain in compliance with all applicable federal, state, local
and foreign statutes, orders, regulations, rules and ordinances (including,
without limitation, Environmental Laws and statutes, orders, regulations, rules
and ordinances relating to taxes, employer and employee contributions and
similar items, securities, ERISA or employee health and safety) the failure with
which to comply would have a Material Adverse Effect on such Borrower. Following
any determination by Lender that there is non-compliance, or any condition which
requires any action by or on behalf of a Borrower in order to avoid
non-compliance, with any Environmental Law, at such Borrower's expense cause an
independent environmental engineer acceptable to Lender to conduct such tests of
the relevant site(s) as are appropriate and prepare and deliver a report setting
forth the results of such tests, a proposed plan for remediation and an estimate
of the costs thereof.



                                      -30-


                  (d) INSPECTION AND AUDITS.

                  Each Borrower shall permit Lender, or any Persons designated
by it, to call at such Borrower's places of business at any reasonable times,
and, without hindrance or delay, to inspect the Collateral and to inspect,
audit, check and make extracts from such Borrower's books, records, journals,
orders, receipts and any correspondence and other data relating to such
Borrower's business, the Collateral or any transactions between the parties
hereto, and shall have the right to make such verification concerning such
Borrower's business as Lender may consider reasonable under the circumstances.
Each Borrower shall furnish to Lender such information relevant to Lender's
rights under this Agreement and the Other Agreements as Lender shall at any time
and from time to time request. Lender, through its officers, employees or agents
shall have the right, at any time and from time to time, in Lender's name, to
verify the validity, amount or any other matter relating to any of such
Borrower's Accounts, by mail, telephone, telecopy, electronic mail, or
otherwise, provided that prior to the occurrence of an Event of Default, Lender
shall conduct such verification in the name of a nominee of Lender or in such
Borrower's name. Each Borrower authorizes Lender to discuss the affairs,
finances and business of such Borrower with any officers, employees or directors
of such Borrower or with its Parent or any Affiliate or the officers, employees
or directors of its Parent or any Affiliate, and to discuss the financial
condition of such Borrower with such Borrower's independent public accountants.
Any such discussions shall be without liability to Lender or to Borrowers'
independent public accountants. Borrowers shall pay to Lender all customary fees
and all costs and out-of-pocket expenses incurred by Lender in the exercise of
its rights hereunder, and all of such fees, costs and expenses shall constitute
Liabilities hereunder, shall be payable on demand and, until paid, shall bear
interest at the highest rate then applicable to Loans hereunder.

                  (e) INSURANCE.

                  Each Borrower shall:

                           (i) Keep the Collateral properly housed and insured
         for the full insurable value thereof against loss or damage by fire,
         theft, explosion, sprinklers, collision (in the case of motor vehicles)
         and such other risks as are customarily insured against by Persons
         engaged in businesses similar to that of such Borrower, with such
         companies, in such amounts, with such deductibles, and under policies
         in such form, as shall be satisfactory to Lender. Original (or
         certified) copies of such policies of insurance have been or shall be,
         within ninety (90) days of the date hereof, delivered to Lender,
         together with evidence of payment of all premiums therefor, and shall
         contain an endorsement, in form and substance acceptable to Lender,
         showing loss under such insurance policies payable to Lender. Such
         endorsement, or an independent instrument furnished to Lender, shall
         provide that the insurance company shall give Lender at least thirty
         (30) days written notice before any such policy of insurance is altered
         or canceled and that no act, whether willful or negligent, or default
         of such Borrower or any other Person shall affect the right of Lender
         to



                                      -31-


         recover under such policy of insurance in case of loss or damage. In
         addition, each Borrower shall cause to be executed and delivered to
         Lender an assignment of proceeds of its business interruption insurance
         policies. Each Borrower hereby directs all insurers under all policies
         of insurance to pay all proceeds payable thereunder directly to Lender.
         Each Borrower irrevocably makes, constitutes and appoints Lender (and
         all officers, employees or agents designated by Lender) as such
         Borrower's true and lawful attorney (and agent-in-fact) for the purpose
         of making, settling and adjusting claims under such policies of
         insurance, endorsing the name of such Borrower on any check, draft,
         instrument or other item of payment for the proceeds of such policies
         of insurance and making all determinations and decisions with respect
         to such policies of insurance, provided however, that if no Event of
         Default shall have occurred and is continuing, Borrowers may make,
         settle and adjust claims involving less than $500,000.00 in the
         aggregate without Lender's consent.

                           (ii) Maintain, at its expense, such public liability
         and third party property damage insurance as is customary for Persons
         engaged in businesses similar to that of such Borrower with such
         companies and in such amounts, with such deductibles and under policies
         in such form as shall be satisfactory to Lender and original (or
         certified) copies of such policies have been or shall be, within ninety
         (90) days after the date hereof, delivered to Lender, together with
         evidence of payment of all premiums therefor; each such policy shall
         contain an endorsement showing Lender as additional insured thereunder
         and providing that the insurance company shall give Lender at least
         thirty (30) days written notice before any such policy shall be altered
         or canceled.

If a Borrower at any time or times hereafter shall fail to obtain or maintain
any of the policies of insurance required above or to pay any premium relating
thereto, then Lender, without waiving or releasing any obligation or default by
Borrowers hereunder, may (but shall be under no obligation to) obtain and
maintain such policies of insurance and pay such premiums and take such other
actions with respect thereto as Lender deems advisable upon notice to such
Borrower. Such insurance, if obtained by Lender, may, but need not, protect such
Borrower's interests or pay any claim made by or against such Borrower with
respect to the Collateral. Such insurance may be more expensive than the cost of
insurance such Borrower may be able to obtain on its own and may be cancelled
only upon such Borrower providing evidence that it has obtained the insurance as
required above. All sums disbursed by Lender in connection with any such
actions, including, without limitation, court costs, expenses, other charges
relating thereto and reasonable attorneys' fees, shall constitute Loans
hereunder, shall be payable on demand by Borrowers to Lender and, until paid,
shall bear interest at the highest rate then applicable to Loans hereunder.

                  (f) COLLATERAL.

                  Each Borrower shall keep the Collateral in good condition,
repair and order and shall make all necessary repairs to the Equipment and
replacements thereof so that the



                                      -32-


operating efficiency and the value thereof shall at all times be preserved and
maintained in all material respects. Each Borrower shall permit Lender to
examine any of the Collateral at any time and wherever the Collateral may be
located and, each Borrower shall, immediately upon request therefor by Lender,
deliver to Lender any and all evidence of ownership of any of the Equipment
including, without limitation, certificates of title and applications of title.
Each Borrower shall, at the request of Lender, indicate on its records
concerning the Collateral a notation, in form satisfactory to Lender, of the
security interest of Lender hereunder.

                  (g) USE OF PROCEEDS.

                  All monies and other property obtained by a Borrower from
Lender pursuant to this Agreement shall be used solely for business purposes of
such Borrower.

                  (h) TAXES.

                  Each Borrower shall file all required tax returns and pay all
of its taxes when due, subject to any extensions granted by the applicable
taxing authority, including, without limitation, taxes imposed by federal, state
or municipal agencies, and shall cause any liens for taxes to be promptly
released; provided, that such Borrower shall have the right to contest the
payment of such taxes in good faith by appropriate proceedings so long as (i)
the amount so contested is shown on such Borrower's financial statements; (ii)
the contesting of any such payment does not give rise to a lien for taxes; (iii)
such Borrower keeps on deposit with Lender (such deposit to be held without
interest) or a reserve is maintained against such Borrower's availability to
borrow money under subsection 2(a), in either case, in an amount of money which,
in the sole judgment of Lender, is sufficient to pay such taxes and any interest
or penalties that may accrue thereon; and (iv) if such Borrower fails to
prosecute such contest with reasonable diligence, Lender may apply the money so
deposited in payment of such taxes. If a Borrower fails to pay any such taxes
and in the absence of any such contest by such Borrower, Lender may (but shall
be under no obligation to) advance and pay any sums required to pay any such
taxes and/or to secure the release of any lien therefor, and any sums so
advanced by Lender shall constitute Loans hereunder, shall be payable by such
Borrower to Lender on demand, and, until paid, shall bear interest at the
highest rate then applicable to Loans hereunder.

                  (i) INTELLECTUAL PROPERTY.

                  Each Borrower shall maintain adequate licenses, patents,
patent applications, copyrights, service marks, trademarks, trademark
applications, tradestyles and trade names to continue its business as heretofore
conducted by it or as hereafter conducted by it unless the failure to maintain
any of the foregoing could not reasonably be expected to have a Material Adverse
Effect on such Borrower.



                                      -33-


                  (j) CHECKING ACCOUNTS.

Each Borrower shall maintain all of its demand deposit accounts, including its
controlled disbursement account, with LaSalle Bank; provided that each Borrower
may maintain payroll accounts and petty cash accounts at other financial
institutions so long as the aggregate amount of funds contained in all such
petty cash accounts shall not exceed $100,000.00 at any time. Normal charges

Material Adverse Effect on such Borrower; (ii) such actions would not affect the
obligations of such Borrower to Lender; (iii) such



                                      -35-

                  16. REMEDIES UPON AN EVENT OF DEFAULT.

                  (a) Upon the occurrence and during the continuance of an Event
of Default described in subsection 15(g) hereof, all of the Liabilities shall
immediately and automatically become due and payable, without notice of any
kind. Upon the occurrence of any other Event of Default, all Liabilities may, at
the option of Lender, and without demand, notice or legal process of any kind,
be declared, and immediately shall become, due and payable.

                  (b) Upon the occurrence and during the continuance of an Event
of Default, Lender may exercise from time to time any rights and remedies
available to it under the Uniform Commercial Code and any other applicable law
in addition to, and not in lieu of, any rights and remedies expressly granted in
this Agreement or in any of the Other Agreements and all of Lender's rights and
remedies shall be cumulative and non-exclusive to the extent permitted by law.
In particular, but not by way of limitation of the foregoing, Lender may,
without notice, demand or legal process of any kind, take possession of any or
all of the Collateral (in addition to Collateral of which it already has
possession), wherever it may be found, and for that purpose may pursue the same
wherever it may be found, and may enter onto any of Borrowers' premises where
any of the Collateral may be, and search for, take possession of, remove, keep
and store any of the Collateral until the same shall be sold or otherwise
disposed of, and Lender shall have the right to store the same at any of
Borrowers' premises without cost to Lender. At Lender's request, each Borrower
shall, at Borrowers' expense, assemble the Collateral and make it available to
Lender at one or more places to be designated by Lender and reasonably
convenient to Lender and such Borrower. Each Borrower recognizes that if a
Borrower fails to perform, observe or discharge any of its Liabilities under
this Agreement or the Other Agreements, no remedy at law will provide adequate
relief to Lender, and agrees that Lender shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages. Any notification of intended disposition of any of the
Collateral required by law will be deemed to be a reasonable authenticated
notification of disposition if given at least ten (10) days prior to such
disposition and such notice shall (i) describe Lender and the applicable
Borrower(s), (ii) describe the Collateral that is the subject to the intended
disposition, (iii)



                                      -40-


state the method of the intended disposition, (iv) state that the applicable
Borrower(s) is entitled to an accounting of the Liabilities and state the
charge, if any, for an accounting and (v) state the time and place of any public
disposition or the time after which any private sale is to be made. Lender may
disclaim any warranties that might arise in connection with the sale, lease or
other disposition of the Collateral and has no obligation to provide any
warranties at such time. Any Proceeds of any disposition by Lender of any of the
Collateral may be applied by Lender to the payment of expenses in connection
with the Collateral, including, without limitation, legal expenses and
reasonable attorneys' fees, and any balance of such Proceeds may be applied by
Lender toward the payment of such of the Liabilities, and in such order of
application, as Lender may from time to time elect.

                  17. CONDITIONS PRECEDENT.

                  The obligation of Lender to fund the Term Loan, to fund the
initial Revolving Loan, and to issue or cause to be issued the initial Letter of
Credit, is subject to the satisfaction or waiver on or before the date hereof of
the following conditions precedent:

                  (a) Lender shall have received each of the agreements,
opinions, reports, approvals, consents, certificates and other documents set
forth on the closing document list attached hereto as Schedule 17(a) (the
"CLOSING DOCUMENT LIST") in each case in form and substance satisfactory to
Lender;

                  (b) Since September 30, 2003, no event shall have occurred
which has had or could reasonably be expected to have a Material Adverse Effect
on any Obligor, as determined by Lender in its sole discretion, determined in
good faith;

                  (c) Lender shall have received payment in full of all fees and
expenses payable to it by Borrowers or any other Person in connection herewith,
on or before disbursement of the initial Loans hereunder;

                  (d) Lender shall have determined that immediately after giving
effect to (A) the making of the initial Loans, including without limitation the
Term Loan and the Revolving Loans, if any, requested to be made on the date
hereof, (B) the issuance of the initial Letter of Credit, if any, requested to
be made on such date, (C) the payment of all fees due upon such date and (D) the
payment or reimbursement by Borrowers of Lender for all closing costs and
expenses incurred in connection with the transactions contemplated hereby,
Borrowers have Excess Availability of not less than Five Hundred Thousand and
No/100 Dollars ($500,000.00);

                  (e) The Obligors shall have executed and delivered to Lender
all such other documents, instruments and agreements which Lender determines are
reasonably necessary to consummate the transactions contemplated hereby,
including, without limitation, a secured Continuing Unconditional Guaranty of
Robinson Turney International, Inc.; and



                                      -41-


                  (f) Renaissance US Growth and Income Trust PLC, Renaissance
Capital Group, Inc., John D. Higgins and Begnt Bodin shall each execute and
deliver a Subordination Agreement in form and substance satisfactory to Lender.
In addition, the maturity dates with respect to all such indebtedness shall be
extended to a date subsequent to the Original Term.

                  18. JOINT AND SEVERAL LIABILITY.

                  (a) Notwithstanding anything to the contrary contained herein,
all Liabilities of each Borrower hereunder shall be joint and several
obligations of Borrowers.

                  (b) Notwithstanding any provisions of this Agreement to the
contrary, it is intended that the joint and several nature of the Liabilities of
Borrowers and the liens and security interests granted by Borrowers to secure
the Liabilities, not constitute a "Fraudulent Conveyance" (as defined below).
Consequently, Lender and Borrowers agree that if the Liabilities of a Borrower,
or any liens or security interests granted by such Borrower securing the
Liabilities would, but for the application of this sentence, constitute a
Fraudulent Conveyance, the Liabilities of such Borrower and the liens and
security interests securing such Liabilities shall be valid and enforceable only
to the maximum extent that would not cause such Liabilities or such lien or
security interest to constitute a Fraudulent Conveyance, and the Liabilities of
such Borrower and this Agreement shall automatically be deemed to have been
amended accordingly. For purposes hereof, "Fraudulent Conveyance" means a
fraudulent conveyance under Section 548 of Chapter 11 of Title II of the United
States Code (11 U.S.C. Section 101, et seq.), as amended (the "Bankruptcy Code")
or a fraudulent conveyance or fraudulent transfer under the applicable
provisions of any fraudulent conveyance or fraudulent transfer law or similar
law of any state, nation or other governmental unit, as in effect from time to
time.

                  (c) Each Borrower assumes responsibility for keeping itself
informed of the financial condition of each other Borrower, and any and all
endorsers and/or guarantors of any instrument or document evidencing all or any
part of such other Borrower's Liabilities and of all other circumstances bearing
upon the risk of nonpayment by such other Borrowers of their Liabilities and
each Borrower agrees that Lender shall not have any duty to advise such Borrower
of information known to Lender regarding such condition or any such
circumstances or to undertake any investigation not a part of its regular
business routine. If Lender, in its sole discretion, undertakes at any time or
from time to time to provide any such information to a Borrower, Lender shall
not be under any obligation to update any such information or to provide any
such information to such Borrower on any subsequent occasion.

                  (d) Lender is hereby authorized, without notice or demand and
without affecting the liability of a Borrower hereunder, to, at any time and
from time to time, (i) renew, extend, accelerate or otherwise change the time
for payment of, or other terms relating to a Borrower's Liabilities or otherwise
modify, amend or change the terms of any promissory note or other agreement,
document or instrument now or hereafter executed by a



                                      -42-


Borrower and delivered to Lender; (ii) accept partial payments on a Borrower's
Liabilities; (iii) take and hold security or collateral for the payment of a
Borrower's Liabilities hereunder or for the payment of any guaranties of a
Borrower's Liabilities or other liabilities of a Borrower and exchange, enforce,
waive and release any such security or collateral; (iv) apply such security or
collateral and direct the order or manner of sale thereof as Lender, in its sole
discretion, may determine; and (v) settle, release, compromise, collect or
otherwise liquidate a Borrower's Liabilities and any security or collateral
therefor in any manner, without affecting or impairing the obligations of the
other Borrowers. Lender shall have the exclusive right to determine the time and
manner of application of any payments or credits, whether received from a
Borrower or any other source, and such determination shall be binding on such
Borrower. All such payments and credits may be applied, reversed and reapplied,
in whole or in part, to any of a Borrower's Liabilities as Lender shall
determine in its sole discretion without affecting the validity or
enforceability of the Liabilities of the other Borrowers.

                  (e) Each Borrower hereby agrees that, except as hereinafter
provided, its obligations hereunder shall be unconditional, irrespective of (i)
the absence of any attempt to collect a Borrower's Liabilities from any Borrower
or any guarantor or other action to enforce the same; (ii) the waiver or consent
by Lender with respect to any provision of any instrument evidencing Borrowers'
Liabilities, or any part thereof, or any other agreement heretofore, now or
hereafter executed by a Borrower and delivered to Lender; (iii) failure by
Lender to take any steps to perfect and maintain its security interest in, or to
preserve its rights to, any security or collateral for Borrowers' Liabilities;
(iv) the institution of any proceeding under the Bankruptcy Code, or any similar
proceeding, by or against a Borrower or Lender's election in any such proceeding
of the application of Section 1111(b)(2) of the Bankruptcy Code; (v) any
borrowing or grant of a security interest by any Borrower as
debtor-in-possession, under Section 364 of the Bankruptcy Code; (vi) the
disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of
Lender's claim(s) for repayment of any of Borrowers' Liabilities; or (vii) any
other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a guarantor.

                  (f) No payment made by or for the account of a Borrower
including, without limitations, (i) a payment made by such Borrower on behalf of
another Borrower's Liabilities or (ii) a payment made by any other person under
any guaranty, shall entitle such Borrower, by subrogation or otherwise, to any
payment from such other Borrower or from or out of such other Borrower's
property and such Borrower shall not exercise any right or remedy against such
other Borrower or any property of such other Borrower by reason of any
performance of such Borrower of its joint and several obligations hereunder.

                  19. INDEMNIFICATION.

                  Each Borrower agrees to defend (with counsel satisfactory to
Lender), protect, indemnify and hold harmless Lender, each affiliate or
subsidiary of Lender, and each of their respective shareholders, members,
officers, directors, managers, employees, attorneys and



                                      -43-


agents (each an "INDEMNIFIED PARTY") from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, claims,
costs, expenses and disbursements of any kind or nature (including, without
limitation, the disbursements and the reasonable fees of counsel for each
Indemnified Party in connection with any investigative, administrative or
judicial proceeding, whether or not the Indemnified Party shall be designated a
party thereto), which may be imposed on, incurred by, or asserted against, any
Indemnified Party (whether direct, indirect or consequential and whether based
on any federal, state or local laws or regulations, including, without
limitation, securities laws and regulations, Environmental Laws and commercial
laws and regulations, under common law or in equity, or based on contract or
otherwise) in any manner relating to or arising out of this Agreement or any
Other Agreement, or any act, event or transaction related or attendant thereto,
the making or issuance and the management of the Loans or any Letters of Credit
or the use or intended use of the proceeds of the Loans or any Letters of
Credit; provided, however, that no Borrower shall have any obligation hereunder
to any Indemnified Party with respect to matters caused by or resulting from the
willful misconduct or gross negligence of such Indemnified Party. To the extent
that the undertaking to indemnify set forth in the preceding sentence may be
unenforceable because it is violative of any law or public policy, each Borrower
shall satisfy such undertaking to the maximum extent permitted by applicable
law. Any liability, obligation, loss, damage, penalty, cost or expense covered
by this indemnity shall be paid to each Indemnified Party on demand, and,
failing prompt payment, shall, together with interest thereon at the highest
rate then applicable to Loans hereunder from the date incurred by each
Indemnified Party until paid by Borrowers, be added to the Liabilities of
Borrowers and be secured by the Collateral. The provisions of this Section 18
shall survive the satisfaction and payment of the other Liabilities and the
termination of this Agreement.

                  20. NOTICE.

                  All written notices and other written communications with
respect to this Agreement shall be sent by ordinary, certified or overnight
mail, by telecopy or delivered in person, and in the case of Lender shall be
sent to it at 135 South LaSalle Street, Chicago, Illinois 60603-4105, attention:
Susan Hamilton, facsimile number: (312) 904-6450, and in the case of Borrowers
shall be sent to them at their respective principal places of business set forth

notices shall be deemed received upon actual receipt thereof or refusal of
delivery.

                  21. CHOICE OF GOVERNING LAW; CONSTRUCTION; FORUM SELECTION.

                  This Agreement and the Other Agreements are submitted by
Borrowers to Lender for Lender's acceptance or rejection at Lender's principal
place of business as an offer by Borrowers to borrow monies from Lender now and
from time to time hereafter, and shall not be binding upon Lender or become
effective until accepted by Lender, in writing, at said place of business. If so
accepted by Lender, this Agreement and the Other Agreements shall



                                      -44-


be deemed to have been made at said place of business. THIS AGREEMENT AND THE
OTHER AGREEMENTS SHALL BE GOVERNED AND CONTROLLED BY THE INTERNAL LAWS OF THE
STATE OF ILLINOIS AS TO INTERPRETATION, ENFORCEMENT, VALIDITY, CONSTRUCTION,
EFFECT, AND IN ALL OTHER RESPECTS, INCLUDING, WITHOUT LIMITATION, THE LEGALITY
OF THE INTEREST RATE AND OTHER CHARGES, BUT EXCLUDING PERFECTION OF THE SECURITY
INTERESTS IN COLLATERAL LOCATED OUTSIDE OF THE STATE OF ILLINOIS, WHICH SHALL BE
GOVERNED AND CONTROLLED BY THE LAWS OF THE RELEVANT JURISDICTION IN WHICH SUCH
COLLATERAL IS LOCATED. If any provision of this Agreement shall be held to be
prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or remaining provisions of this
Agreement.

                  To induce Lender to accept this Agreement, each Borrower
irrevocably agrees that, subject to Lender's sole and absolute election, ALL
ACTIONS OR PROCEEDINGS IN ANY WAY, MANNER OR RESPECT, ARISING OUT OF OR FROM OR
RELATED TO THIS AGREEMENT, THE OTHER AGREEMENTS OR THE COLLATERAL SHALL BE
LITIGATED IN COURTS HAVING SITUS WITHIN THE CITY OF CHICAGO, STATE OF ILLINOIS.
EACH BORROWER HEREBY CONSENTS AND SUBMITS TO THE JURISDICTION OF ANY LOCAL,
STATE OR FEDERAL COURTS LOCATED WITHIN SAID CITY AND STATE. EACH BORROWER HEREBY
WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS AND AGREES THAT ALL SUCH SERVICE
OF PROCESS MAY BE MADE UPON SUCH BORROWER BY CERTIFIED OR REGISTERED MAIL,
RETURN RECEIPT REQUESTED, ADDRESSED TO SUCH BORROWER, AT THE ADDRESS SET FORTH
FOR NOTICE IN THIS AGREEMENT AND SERVICE SO MADE SHALL BE COMPLETE TEN (10) DAYS
AFTER THE SAME HAS BEEN POSTED. Lender agrees to endeavor to provide a copy of
such process to the law firm of Gray, Layton, Kersh, Solomon, Sigmon, Furr &
Smith, P.A. by mail at the address of 516 South New Hope Road, Gastonia, North
Carolina 28053-2636 or by facsimile transmission at facsimile number (704)
866-8010. Failure of Lender to provide a copy of such process shall not impair
Lender's rights hereunder, create a cause of action against Lender or create any
claim or right on behalf of Borrowers or any third party. EACH BORROWER HEREBY
WAIVES ANY RIGHT IT MAY HAVE TO TRANSFER OR CHANGE THE VENUE OF ANY LITIGATION
BROUGHT AGAINST SUCH BORROWER BY LENDER IN ACCORDANCE WITH THIS SECTION.

                  22. MODIFICATION AND BENEFIT OF AGREEMENT.

                  This Agreement and the Other Agreements may not be modified,
altered or amended except by an agreement in writing signed by each Borrower or
such other Person who is a party to such Other Agreement and Lender. No Borrower
may sell, assign or transfer this Agreement, or the Other Agreements or any
portion thereof, including, without



                                      -45-


limitation, such Borrower's rights, titles, interest, remedies, powers or duties
hereunder and thereunder. Each Borrower hereby consents to Lender's sale,
assignment, transfer or other disposition, at any time and from time to time
hereafter, of this Agreement, or the Other Agreements, or of any portion
thereof, or participations therein, including, without limitation, Lender's
rights, titles, interest, remedies, powers and/or duties and agrees that it
shall execute and deliver such documents as Lender may request in connection
with any such sale, assignment, transfer or other disposition.

                  23. HEADINGS OF SUBDIVISIONS.

                  The headings of subdivisions in this Agreement are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of this Agreement.

                  24. POWER OF ATTORNEY.

                  Each Borrower acknowledges and agrees that its appointment of
Lender as its attorney and agent-in-fact for the purposes specified in this
Agreement is an appointment coupled with an interest and shall be irrevocable
until all of the Liabilities are satisfied and paid in full and this Agreement
is terminated.

                  25. CONFIDENTIALITY.

                  Lender hereby agrees to use commercially reasonable efforts to
assure that any and all information relating to such Borrower which is (i)
furnished by such Borrower to Lender (or to any affiliate of Lender); and (ii)
non-public, confidential or proprietary in nature, shall be kept confidential by
Lender or such affiliate in accordance with applicable law; provided, however,
that such information and other credit information relating to such Borrower may
be distributed by Lender or such affiliate to Lender's or such affiliate's
directors, managers, officers, employees, attorneys, affiliates, assignees,
participants, auditors, agents and regulators, and upon the order of a court or
other governmental agency having jurisdiction over Lender or such affiliate, to
any other party. Each Borrower and Lender further agree that this provision
shall survive the termination of this Agreement. Notwithstanding the foregoing,
each Borrower hereby consents to Lender publishing a tombstone or similar
advertising material relating to the financing transaction contemplated by this
Agreement. Notwithstanding anything to the contrary set forth herein or in any
other agreement to which the parties hereto are parties or by which they are
bound, the obligations of confidentiality contained herein and therein, as they
relate the transactions contemplated by this Agreement and the Other Agreements
(the "Transaction"), shall not apply to the federal tax structure or federal tax
treatment of the Transaction, and each party hereto (and any employee,
representative, agent or any party hereto) may disclose to any and all persons,
without limitation of any kind, the federal tax structure and federal tax
treatment of the Transaction. In addition, each party hereto acknowledges that
it has no proprietary or



                                      -46-


exclusive rights to the federal tax structure of the Transaction or any federal
tax matter or federal tax treatment related to the Transaction.

                  26. COUNTERPARTS.

                  This Agreement, any of the Other Agreements and any
amendments, waivers, consents or supplements may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which, when so executed and delivered, shall be deemed an original, but all of
which counterparts together shall constitute but one agreement.

                  27. ELECTRONIC SUBMISSIONS.

                  Upon not less than thirty (30) days' prior written notice (the
"APPROVED ELECTRONIC FORM NOTICE"), Lender may permit or require that any of the
documents, certificates, forms, deliveries or other communications, authorized,
required or contemplated by this Agreement or the Other Agreements, be submitted
to Lender in "APPROVED ELECTRONIC FORM" (as hereafter defined), subject to any
reasonable terms, conditions and requirements in the applicable Approved
Electronic Forms Notice. For purposes hereof "ELECTRONIC FORM" means e-mail,
e-mail attachments, data submitted on web-based forms or any other communication
method that delivers machine readable data or information to Lender, and
"APPROVED ELECTRONIC FORM" means an Electronic Form that has been approved in
writing by Lender (which approval has not been revoked or modified by Lender)
and sent to Borrowers in an Approved Electronic Form Notice. Except as otherwise
specifically provided in the applicable Approved Electronic Form Notice, any
submissions made in an applicable Approved Electronic Form shall have the same
force and effect that the same submissions would have had if they had been
submitted in any other applicable form authorized, required or contemplated by
this Agreement or the Other Agreements.

                  28. WAIVER OF JURY TRIAL; OTHER WAIVERS.

                  (a) EACH BORROWER AND LENDER EACH HEREBY WAIVES ALL RIGHTS TO
TRIAL BY JURY IN ANY ACTION OR PROCEEDING WHICH PERTAINS DIRECTLY OR INDIRECTLY
TO THIS AGREEMENT, ANY OF THE OTHER AGREEMENTS, THE LIABILITIES, THE COLLATERAL,
ANY ALLEGED TORTIOUS CONDUCT BY A BORROWER OR LENDER OR WHICH, IN ANY WAY,
DIRECTLY OR INDIRECTLY, ARISES OUT OF OR RELATES TO THE RELATIONSHIP BETWEEN A
BORROWER AND LENDER. IN NO EVENT SHALL LENDER BE LIABLE FOR LOST PROFITS OR
OTHER SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES.

                  (b) Each Borrower hereby waives demand, presentment, protest
and notice of nonpayment, and further waives the benefit of all valuation,
appraisal and exemption laws.



                                      -47-


                  (c) Each Borrower hereby waives the benefit of any law that
would otherwise restrict or limit Lender or any affiliate of Lender in the
exercise of its right, which is hereby acknowledged and agreed to, to set-off
against the Liabilities, without notice at any time hereafter, any indebtedness,
matured or unmatured, owing by Lender or such affiliate of Lender to such
Borrower, including, without limitation any Deposit Account at Lender or such
affiliate.

                  (d) EACH BORROWER HEREBY WAIVES ALL RIGHTS TO NOTICE AND
HEARING OF ANY KIND PRIOR TO THE EXERCISE BY LENDER OF ITS RIGHTS TO REPOSSESS
THE COLLATERAL OF SUCH BORROWER WITHOUT JUDICIAL PROCESS OR TO REPLEVY, ATTACH
OR LEVY UPON SUCH COLLATERAL, PROVIDED THAT IN THE EVENT THAT LENDER SEEKS TO
ENFORCE ITS RIGHTS HEREUNDER BY JUDICIAL PROCESS OR SELF HELP, LENDER SHALL
PROVIDE BORROWERS WITH SUCH NOTICES AS ARE REQUIRED BY LAW.

                  (e) Lender's failure, at any time or times hereafter, to
require strict performance by a Borrower of any provision of this Agreement or
any of the Other Agreements shall not waive, affect or diminish any right of
Lender thereafter to demand strict compliance and performance therewith. Any
suspension or waiver by Lender of an Event of Default under this Agreement or
any default under any of the Other Agreements shall not suspend, waive or affect
any other Event of Default under this Agreement or any other default under any
of the Other Agreements, whether the same is prior or subsequent thereto and
whether of the same or of a different kind or character. No delay on the part of
Lender in the exercise of any right or remedy under this Agreement or any Other
Agreement shall preclude other or further exercise thereof or the exercise of
any right or remedy. None of the undertakings, agreements, warranties, covenants
and representations of Borrowers contained in this Agreement or any of the Other
Agreements and no Event of Default under this Agreement or default under any of
the Other Agreements shall be deemed to have been suspended or waived by Lender
unless such suspension or waiver is in writing, signed by a duly authorized
officer of Lender and directed to Borrowers specifying such suspension or
waiver.
