                                   AGREEMENT

     This Agreement, dated December 3, 2001 (this "Agreement"), is entered into
by and among UnitedGlobalCom, Inc., a Delaware corporation (the "Company"), UIH
Funding Corp. ("Funding"), Salomon Smith Barney Inc. ("SSB"), TD Securities
(USA) Inc. ("TD"), J.P. Morgan Securities Inc. (formerly known as Chase
Securities Inc., "JP" and, together with Funding, SSB and TD, the "Purchasers"),
Donaldson, Lufkin & Jenrette Securities Corporation ("DLJSC").

                                   RECITALS
                                   --------

     WHEREAS, Funding is the holder of all of the outstanding 10 7/8% Senior
Discount Notes due 2009 (the "Notes") issued under the indenture (the
"Indenture"), dated as of April 29, 1999, between the Company and Firstar Bank,
N.A. (f/k/a Firstar Bank of Minnesota, N.A.), as trustee (the "Trustee");

     WHEREAS, Funding, SSB, TD and JP are the beneficial holders of all of the
outstanding Notes in the respective aggregate principal amounts at maturity set
forth on Schedule 1 hereto;

     WHEREAS, in consideration of, and as a condition to, the Purchasers'
purchase of the Notes, the Company entered into the Fee Letter, dated April 29,
1999 (as amended pursuant to that certain Amendment to Fee Letter, dated May 13,
1999, the "Original Fee Letter"), among the Company, the Purchasers and DLJSC,
setting forth certain fees, terms and provisions relating to the distribution
and resale of the Notes;

     WHEREAS, pursuant to Section 3(c) of the Original Fee Letter, the Company
has agreed (the "Make-Whole Obligation") that if the Notes are sold pursuant to
a Resale (as defined in the Original Fee Letter) for less than the then accreted
value of such Notes sold, the Company would pay promptly to the Purchasers a sum
in cash equal to the difference between the resale price of such Notes and the
accreted value of such Notes as of the Resale Pricing Date (as such term is used
in the Original Fee Letter);

     WHEREAS, the Company, the Purchasers and DLJSC amended the Original Fee
Letter pursuant to that certain Letter Agreement, dated May 23, 2001, among the
<PAGE>

Company, the Purchasers and DLJSC (the "Letter Agreement," and, together with
the Original Fee Letter, the "Fee Letter") pursuant to which the Purchasers
agreed to modify their rights to resell the Notes as specified therein and
agreed to waive certain rights in connection with the incurrence of certain
indebtedness by one of the Company's subsidiaries in consideration for certain
guarantees and other agreements by the Company and its affiliate, New
UnitedGlobalCom, Inc., a Delaware corporation ("New United");

     WHEREAS, the Company and the Purchasers have determined that the Accreted
Value (as defined in the Indenture) of the Notes is $275,062,174.52 but the
value of the Notes would be no more than $33,753,108.73 if the Notes were sold
at this time to a third party and, therefore, the Make-Whole Obligation would be
substantial and that a resale of the Notes to a third party would be materially
adverse to the Company;

     WHEREAS, concurrently with the execution of this Agreement, the Company has
agreed to sell certain shares of the Company's Class A Common Stock, par value
$0.01 per share (the "Common Shares") to Liberty Media Corporation ("Liberty")
for net cash proceeds of $20,000,000 (the "Common Shares Proceeds");

     WHEREAS, the Company has proposed, and the Purchasers have agreed, to
resell the Notes to the Company for $20,000,000, which will be paid from the net
cash proceeds received by the Company from the sale of the Common Shares,
instead of reselling the Notes to a third party;

     WHEREAS, therefore, the Company has proposed, and the Purchasers have
agreed on the terms set forth herein, to accept payments from the Company in
satisfaction of the Make-Whole Obligation equal to $241,309,065.79 (such amount,
"Reimbursement Amount");

     WHEREAS, Liberty has agreed to repay $241,309,065.79 (such amount, the
"Repayment Amount") in respect of principal and accrued interest on one or more
loans (the "Liberty Loans") extended by the Company (or its subsidiaries) to
Liberty; and

     WHEREAS,  Liberty has proposed, and the Purchasers have agreed, that the
Purchasers (or their affiliates) will purchase new senior notes of Liberty.

     2. LOANS.

     (a) Revolving Loans.

     Subject to the terms and conditions of this Agreement and the Other
Agreements, during the Original Term and any Renewal Term, Lender will make
revolving loans and advances to Borrowers (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%), less such reserves as Lender
     elects, in its sole discretion, to establish from time to time, including,
     without limitation, a reserve in an amount determined by Lender if Dilution
     exceeds five percent (5%) of Eligible Accounts; plus

          (ii) Up to (A) sixty percent (60%) of the lower of cost or market
     value of Eligible Inventory at locations that use a perpetual inventory
     accounting system or that perform monthly physical counts (less such
     reserves as Lender elects, in its sole discretion, to establish from time
     to time) and up to forty percent (40%) of the lower of cost or market value
     of other Eligible Inventory (less such reserves as Lender elects, in its
     sole discretion, to establish from time to time), or (B) Fourteen Million
     and No/100 Dollars ($14,000,000.00), whichever is less; plus

          (iii) Up to sixty percent (60%) against the face amount of commercial
     Letters of Credit issued or guaranteed by Lender on behalf of such Borrower
     for the purpose of purchasing Eligible Inventory (less such reserves as
     Lender elects, in its sole discretion, to establish from time to time);
     provided, that such commercial Letters of Credit are in form and substance
     satisfactory to Lender; minus

          (iv) A reserve equal to the amount of the accrued and unpaid interest
     from time to time on the Subordinated Notes (whether or not such interest
     is due) and such other reserves as Lender elects, in its sole discretion,
     to establish from time to time;

provided, that the sum of the advances to all Borrowers with respect to clauses
(ii) and (iii) above shall at no time exceed Fourteen Million and No/100 Dollars
($14,000,000.00).

     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 Obligations and (ii) the Maximum 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 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

                                       -11-

<PAGE>

and Lender shall apply such payment to the Revolving Loans in such order as
Lender shall determine in its sole discretion.

     Each Borrower hereby authorizes Lender, in its sole discretion, to charge
Borrowers' account 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 10:30 A.M. (Chicago time) for such
day, of its request for a Revolving Loan as a Prime Rate Loan, and at least
three (3) Business Days prior notice of its request for a Revolving Loan as a
LIBOR Rate Loan, in which notice such Borrower shall specify the amount of the
proposed borrowing and the proposed borrowing date; provided, however, that no
such request may be made at a time when there exists an Event of Default or an
event which, with the passage of time or giving of notice, will become an Event
of Default. 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 control 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 a Borrower, or deemed to be requested by a
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 the
requesting 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 the requesting Borrower and Lender from time to time, or
elsewhere if pursuant to a written direction from such Borrower.

     (b) Repayments.

     Unless due earlier pursuant to the other provisions of this Agreement
(including Section 16(a)), the Revolving Loans and all other Liabilities 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.

                                       -12-

<PAGE>

     (c) 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 the 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 Three Million and No/100 Dollars
($3,000,000.00). Payments made by Lender to any Person on account of any Letter
of Credit shall constitute Loans hereunder and each Borrower agrees that each
payment made by the issuer of a Letter of Credit in respect of a Letter of
Credit issued on behalf of such Borrower shall constitute a request by such
Borrower for a Loan to reimburse such issuer. Borrowers shall remit to Lender
each month a Letter of Credit fee equal to three percent (3.0%) 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 issuance fees and
administrative charges of the issuer of the Letter of Credit for issuance,
amendment, negotiation, renewal or extension of any Letter of Credit, which
shall not be less than Two Hundred Fifty and No/100 Dollars ($250.00) for any
transaction.

     (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 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

                                       -13-

<PAGE>

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 (provided, that the
initial Letter of Credit issued to support the Tennessee IRB may expire on
December 15, 2003) 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.

     Subject to the terms and conditions set forth below, the Loans shall bear
interest at the per annum rate of interest set forth in subsection (i), (ii) or
(iii) below:

          (i) The Prime Rate in effect from time to time, payable on the last
     Business Day of each 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.

          (ii) Two hundred seventy-five (275) basis points in excess of the
     LIBOR Rate for the applicable Interest Period, such rate to remain fixed
     for such Interest Period. "Interest Period" shall mean any continuous
     period of thirty (30), sixty (60) or ninety (90) days, as selected from
     time to time by the Borrower requesting such LIBOR Rate Loan by irrevocable
     notice (in writing, by telex, telegram or cable) given to Lender not less
     than three (3) Business Days prior to the first day of each respective
     Interest Period; provided, that: (A) each such period occurring after such
     initial period shall commence on the day on which the

                                       -14-

<PAGE>

     immediately preceding period expires; (B) the final Interest Period shall
     be such that its expiration occurs on or before the end of the Original
     Term or any Renewal Term; and (C) if for any reason a Borrower shall fail
     to timely select a period, then such Loans shall continue as, or revert to,
     Prime Rate Loans. Interest shall be payable on the last Business Day of
     each month in arrears and on the last Business Day of such Interest Period.

          (iii) Upon the occurrence of an Event of Default and during the
     continuance thereof, the Loans shall bear interest at the rate of two
     percent (2.0%) 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) Other LIBOR Provisions.

          (i) Subject to the provisions of this Agreement, each Borrower shall
     have the option (A) as of any date, to convert all or any part of the Prime
     Rate Loans to, or request that new Loans be made as, LIBOR Rate Loans of
     various Interest Periods, (B) as of the last day of any Interest Period, to
     continue all or any portion of the relevant LIBOR Rate Loans as LIBOR Rate
     Loans; (C) as of the last day of any Interest Period, to convert all or any
     portion of the LIBOR Rate Loans to Prime Rate Loans; and (D) at any time,
     to request new Loans as Prime Rate Loans; provided, that Loans may not be
     continued as or converted to LIBOR Rate Loans, if the continuation or
     conversion thereof would violate the provisions of subsections 4(b)(ii) or
     4(b)(iii) of this Agreement or if an Event of Default has occurred.

          (ii) Lender's determination of the LIBOR Rate as provided above shall
     be conclusive, absent manifest error. Furthermore, if Lender determines, in
     good faith (which determination shall be conclusive, absent manifest
     error), prior to the commencement of any Interest Period that (A) U.S.
     Dollar deposits of sufficient amount and maturity for funding the Loans are
     not available to Lender in the London Interbank Eurodollar market in the
     ordinary course of business, or (B) by reason of circumstances affecting
     the London Interbank Eurodollar market, adequate and fair means do not
     exist for ascertaining the rate of interest to be applicable to the Loans
     requested by a Borrower to be LIBOR Rate Loans or the Loans bearing
     interest at the rates set forth in subsection 4(a)(ii) of this Agreement
     shall not represent the effective pricing to Lender for U.S. Dollar
     deposits of a comparable amount for the relevant period (such as for
     example, but not limited to, official reserve requirements required by
     Regulation D to the extent not given effect in determining the rate),
     Lender shall promptly notify such Borrower and (1) all existing LIBOR Rate
     Loans shall convert to Prime Rate Loans upon the end of the applicable
     Interest Period, and (2) no additional LIBOR Rate Loans shall be made until
     such circumstances are cured.

          (iii) If, after the date hereof, the introduction of, or any change in
     any applicable law, treaty, rule, regulation or guideline or in the
     interpretation or administration thereof by any governmental authority or
     any central bank or other fiscal, monetary or other authority having
     jurisdiction over Lender or its lending

                                       -15-

<PAGE>

     offices (a "Regulatory Change"), shall, in the opinion of counsel to
     Lender, make it unlawful for Lender to make or maintain LIBOR Rate Loans,
     then Lender shall promptly notify the requesting Borrower and (A) the LIBOR
     Rate Loans shall immediately convert to Prime Rate Loans on the last
     Business Day of the then existing Interest Period or on such earlier date
     as required by law and (B) no additional LIBOR Rate Loans shall be made
     until such circumstance is cured.

          (iv) If, for any reason, a LIBOR Rate Loan is paid prior to the last
     Business Day of any Interest Period or if a LIBOR Rate Loan does not occur
     on a date specified by the requesting Borrower in its request (other than
     as a result of a default by Lender), each Borrower agrees to indemnify
     Lender against any loss (including any loss on redeployment of the deposits
     or other funds acquired by Lender to fund or maintain such LIBOR Rate Loan)
     cost or expense incurred by Lender as a result of such prepayment.

          (v) If any Regulatory Change (whether or not having the force of law)
     shall (A) impose, modify or deem applicable any assessment, reserve,
     special deposit or similar requirement against assets held by, or deposits
     in or for the account of or loans by, or any other acquisition of funds or
     disbursements by, Lender; (B) subject Lender or the LIBOR Rate Loans to any
     Tax or change the basis of taxation of payments to Lender of principal or
     interest due from a Borrower to Lender hereunder (other than a change in
     the taxation of the overall net income of Lender); or (C) impose on Lender
     any other condition regarding the LIBOR Rate Loans or Lender's funding
     thereof, and Lender shall determine (which determination shall be
     conclusive, absent any manifest error) that the result of the foregoing is
     to increase the cost to Lender of making or maintaining the LIBOR Rate
     Loans or to reduce the amount of principal or interest received by Lender
     hereunder, then Borrowers shall pay to Lender, on demand, such additional
     amounts as Lender shall, from time to time, determine are sufficient to
     compensate and indemnify Lender from such increased cost or reduced amount.

          (vi) Lender shall receive payments of amounts of principal of and
     interest with respect to the LIBOR Rate Loans free and clear of, and
     without deduction for, any Taxes. If (A) Lender shall be subject to any Tax
     in respect of any LIBOR Rate Loans or any part thereof or, (B) Borrowers
     shall be required to withhold or deduct any Tax from any such amount, the
     LIBOR Rate applicable to such LIBOR Rate Loans shall be adjusted by Lender
     to reflect all additional costs incurred by Lender in connection with the
     payment by Lender or the withholding by a Borrower of such Tax and
     Borrowers shall provide Lender with a statement detailing the amount of any
     such Tax actually paid by Borrowers. Determination by Lender of the amount
     of such costs shall be conclusive, absent manifest error. If after any such
     adjustment any part of any Tax paid by Lender is subsequently recovered by
     Lender, Lender shall reimburse Borrowers to the extent of the amount so
     recovered. A certificate of an officer of Lender setting forth the amount
     of such recovery and the basis therefor shall be conclusive, absent
     manifest error.

          (i) Facilities Fee: Borrowers shall jointly and severally pay to
     Lender a facilities fee equal to one-tenth of one percent (0.10%) per annum
     of the Maximum Loan Limit payable quarterly, which fee shall be fully
     earned by Lender and payable on the date that Lender makes its initial
     disbursement under this Agreement and on each quarterly anniversary of the
     date hereof during the Original Term and any Renewal Term.

          (ii) Closing Fee: Borrowers shall jointly and severally pay to Lender
     a closing fee of Two Hundred Sixty Thousand and No/100 Dollars

          (iii) Unused Line Fee: Borrowers shall jointly and severally pay to
     Lender an unused line fee of three hundred seventy-five hundredths of one
     percent (0.375%) per annum of the difference between the Maximum Loan Limit

     Credit Obligations for each month, which fee shall be fully earned by
     Lender and payable monthly in arrears on the last Business Day of each
     month. Said fee shall be calculated on the basis of a 360 day year.

          (iv) Costs and Expenses: Borrowers shall reimburse Lender for all
     costs and expenses, including, without limitation, legal expenses
     (including reasonable attorneys' fees), incurred by Lender in connection
     with the (i) documentation and consummation of this transaction and any

     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; provided, prior to the occurrence of an Event of Default,
     Borrowers shall not be required to reimburse Lender for costs and expenses,
     other than legal expenses, costs and expenses in connection with Lenders'
     field audits, and those referenced to in the next sentence, in excess of
     Twenty-Five Thousand and No/100 Dollars ($25,000.00) in any year.

                                       -17-

<PAGE>

     Borrowers shall also pay all normal service charges, costs and expenses
     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, constitute Liabilities
     hereunder, shall be payable by Borrowers 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.

     (d) Maximum Interest.

     It is the intent of the parties that the rate of interest and other charges
to Borrowers under this Agreement 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 Borrowers, 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
Borrowers.

Agreements or any Event of Default, may at any time or times hereafter, but

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.

     (e) Intercreditor Agreement.

     The security interest granted herein is subject to the terms of the
Intercreditor Agreement dated November __, 2001 between ACS, Canadian Lender and

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

     Each Borrower shall, at Collateral Agent's request, at any time and from
time to time, authenticate, execute and deliver to Collateral Agent 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 Collateral Agent) and do such other acts and things or cause
third parties to do such other acts and things as Collateral Agent 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 Collateral Agent (and all Persons designated by
Collateral Agent 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 Collateral Agent'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

     7. POSSESSION OF COLLATERAL AND RELATED MATTERS.

     Until an Event of Default has occurred, 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; and (b) use and consume any raw materials, work in process or other
materials normally held by such Borrower for such purpose; 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, Collateral Agent, at LaSalle
Bank, National Association or another financial institution acceptable to
Collateral Agent. Each Borrower shall establish an account (the "Lock Box
Account") in Collateral Agent's name with LaSalle Bank, National Association or
another financial institution acceptable to Collateral Agent, 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, Collateral Agent 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 Collateral Agent, that the
amounts on deposit in such Lock Box Account are the sole and exclusive property
of Collateral Agent, that such financial institution will follow the
instructions of Collateral Agent 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 Account or
against any other account maintained by such financial institution into which
the contents of the Lock Box Account are transferred, and that such financial
institution shall wire, or otherwise transfer in immediately available funds to
Collateral Agent in a manner satisfactory to Collateral Agent, 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 Collateral Agent, whether in respect of the Accounts or as Proceeds
of other Collateral or otherwise, will be applied on account of the Liabilities
in accordance with the terms of this Agreement; provided, that so long as no
Event of Default has occurred, payments received by Collateral Agent shall not
be applied to the unmatured portion of the LIBOR Rate Loans, but shall be held
in a cash collateral account maintained by Collateral Agent, until the earlier
of (i) the last Business Day of the Interest Period applicable to such LIBOR
Rate Loan and (ii) the occurrence of an Event of Default;

                                       -21-

<PAGE>

provided, further, that so long as no Event of Default has occurred, the
immediately available funds in such cash collateral account may be disbursed, at
such Borrower's discretion, to such Borrower so long as after giving effect to
such disbursement, such Borrower's availability under subsection 2(a) hereof at
such time, equals or exceeds the outstanding Revolving Loans at such time. Each
Borrower agrees to pay all fees, costs and expenses in connection with opening
and maintaining the Lock Box Account. All of such fees, costs and expenses if
not paid by a Borrower, may be paid by Collateral Agent and in such event all
amounts paid by Collateral Agent shall constitute Liabilities hereunder, shall
be payable to Collateral Agent 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 payment or Proceeds of Collateral
shall be endorsed by the applicable Borrower to Collateral Agent, and, if that
endorsement of any such item shall not be made for any reason, Collateral Agent
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 Collateral Agent (and all Persons designated by
Collateral Agent 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) Collateral Agent may, at any time and from time to time after the
occurrence and during the continuance 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 Collateral Agent 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 Collateral Agent's sole discretion, to fulfill such Borrower's
obligations under this Agreement and to allow Collateral Agent to collect the
Accounts or other amounts owed to such Borrower. In addition to any other
provision hereof, Collateral Agent may at any time, whether before or after the
occurrence and during the continuance of an Event of Default, at Borrowers'
expense, notify any parties obligated on any of the Accounts to make payment
directly to Collateral Agent of any amounts due or to become due thereunder.

                                       -22-

     (c) For purposes of calculating interest and fees, Collateral Agent shall,
within one (1) Business Day after receipt by Collateral Agent 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
Collateral Agent 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 Collateral Agent shall determine in its sole
discretion, on the day of receipt, subject to actual collection.

     (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

an objection to the items specifically identified.

          (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
     and of any Commercial Tort Claims of 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, assumed name, fictitious
     name or division name not previously disclosed to Lender in writing.

          (v) ERISA Matters. Promptly notify Lender of (x) the occurrence of any

          (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 or any

     (c) Compliance with Laws and Maintenance of Permits.

     Each Borrower shall maintain, and shall cause each Subsidiary to maintain,

without limitation, Environmental Laws and statutes, orders, regulations, rules

     (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 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, telegraph or
otherwise. 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

                                       -32-

<PAGE>

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 under this Section 12(d), 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 (provided, so long as no Event of Default has occurred,
following the first anniversary of this Agreement, Borrowers' shall not be
required to reimburse Lender for more than two field audits in any subsequent
year);

     (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
     Collateral Agent, together with evidence of payment of all premiums
     therefor, and shall contain an endorsement, in form and substance
     acceptable to Collateral Agent, showing loss under such insurance policies
     payable to Collateral Agent. Such endorsement, or an independent instrument
     furnished to Collateral Agent, shall provide that the insurance company
     shall give Collateral Agent 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 Collateral Agent to recover under such
     policy of insurance in case of loss or damage. In addition, each Borrower
     shall cause to be executed and delivered to Collateral Agent an assignment
     of proceeds of its business interruption insurance policies. Each Borrower
     hereby directs all insurers under all policies insuring Collateral against
     damage, loss or hazard to pay all proceeds payable thereunder directly to
     Collateral Agent. Each Borrower irrevocably makes, constitutes and appoints
     Collateral Agent (and all officers, employees or agents designated by
     Collateral Agent) 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.

          (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 Collateral Agent and original (or certified) copies of such
     policies have been or shall be, within ninety (90) days after the date
     hereof, delivered to Collateral Agent, together with evidence of payment of
     all premiums therefor; each such policy shall contain an

                                       -33-

<PAGE>

     endorsement showing Collateral Agent as additional insured thereunder and
     providing that the insurance company shall give Collateral Agent 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 Collateral Agent, 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 Collateral Agent deems advisable. Such
insurance, if obtained by Collateral Agent, 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 Collateral Agent 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 Collateral Agent 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 operating efficiency and the value thereof shall at all times be
preserved and maintained. 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, and shall cause each of its Subsidiaries to, file all
required tax returns and pay all of its taxes when due, 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
or Subsidiary 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 or Subsidiary's financial statements; (ii) the contesting of
any such payment does not give rise to a lien for taxes; (iii) such Borrower or
Subsidiary keeps on deposit with Collateral Agent (such deposit to be held
without interest)

                                       -34-

<PAGE>

an amount of money which, in the sole judgment of Collateral Agent, is
sufficient to pay such taxes and any interest or penalties that may accrue
thereon; and (iv) if such Borrower or Subsidiary fails to prosecute such contest
with reasonable diligence, Collateral Agent may apply the money so deposited in
payment of such taxes. If a Borrower or Subsidiary fails to pay any such taxes
and in the absence of any such contest by such Borrower or Subsidiary, 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 or Subsidiary 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, and shall cause each Subsidiary to, maintain adequate
licenses, patents, patent applications, copyrights, service marks, trademarks,
trademark applications, trade styles and trade names to continue its business as
heretofore conducted by it or as hereafter conducted by it.

     (j) Checking Accounts.

     Each Borrower shall maintain its general checking/controlled disbursement
account with LaSalle Bank. Normal charges shall be assessed thereon. Although no
compensating balance is required, each Borrower must keep monthly balances in
order to merit earnings credits which will cover LaSalle Bank's service charge
for demand deposit account activities.

     13. NEGATIVE COVENANTS.

remedies shall be cumulative and non-exclusive to the extent permitted by law.
In particular, but not by way of

                                       -43-

<PAGE>

limitation of the foregoing, Collateral Agent 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 Collateral Agent
shall have the right to store the same at any of Borrowers' premises without
cost to Collateral Agent. At Collateral Agent's request, each Borrower shall, at
Borrowers' expense, assemble the Collateral and make it available to Collateral
Agent at one or more places to be designated by Collateral Agent and reasonably
convenient to Collateral Agent 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 Collateral Agent, and agrees that Collateral Agent 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 Collateral
Agent and the applicable Borrower(s), (ii) describe the Collateral that is the
subject to the intended disposition, (iii) 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. Collateral Agent 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 Collateral Agent of any of the
Collateral may be applied by Collateral Agent 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 Collateral Agent toward the payment of such of the Liabilities, and in such
order of application, as Collateral Agent may from time to time elect.

     17. CONDITIONS PRECEDENT.

     occurred which has had or could reasonably be expected to have a Material
     Adverse Effect, as determined by Lender in its reasonable discretion;

                                       -44-

<PAGE>

          (iii) 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;

          (iv) Lender shall have determined that immediately after giving effect
     to (A) the making of the initial Loans, (B) the issuance of the initial
     Letters 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, and assuming all of
     Borrowers' trade payables and outstanding debt which remain unpaid more
     than sixty (60) days after the due dates thereof on the date of
     determination, are paid by drawing additional Revolving Loans, on a pro
     forma basis, availability of Borrowers to borrow additional Revolving Loans
     shall not be less than Four Million Five Hundred Thousand and No/100
     Dollars ($4,500,000.00); and

          (v) 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.

     (b) After the initial extensions of credit hereunder, the obligation of
Lender to make any requested Revolving Loan or to issue or cause to issued any
Letter of Credit, is subject to the satisfaction of the conditions precedent set
forth below. Each such request shall constitute a representation and warranty
that such conditions are satisfied:

          (i) All representations and warranties contained in this Agreement and
     the Other Agreements shall be true and correct in all material respects on
     and as of the date of such request, as if then made, other than
     representations and warranties that relate solely to an earlier date;

          (ii) No Event of Default (or any event which with the passage of time
     or giving of notice, or both, would become an Event of Default) shall have
     occurred, or would result from the making of the requested Revolving Loan
     or the issuance of the requested Letter of Credit; and

          (iii) Since December 31, 2000 (except as disclosed in the September
     30, 2001 financial statements delivered to Lender), no event has occurred
     which has had or could reasonably be expected to have a Material Adverse
     Effect.

     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,
Collateral Agent, Lender and Borrowers

                                       -45-

<PAGE>

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 11 of the United States Code (11 U.S.C. ss. 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 the 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 neither Collateral Agent nor Lender shall have any duty to
advise such Borrower of information known to Collateral Agent or Lender
regarding such condition or any such circumstances or to undertake any
investigation not a part of its regular business routine. If either Collateral
Agent or Lender, in its sole discretion, undertakes at any time or from time to
time to provide any such information to a Borrower, neither Collateral Agent nor
Lender shall be under any obligation to update any such information or to
provide any such information to such Borrower on any subsequent occasion.

     (d) Each of Collateral Agent and 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 Borrower and delivered to Collateral Agent or 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 either Collateral Agent or 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. Each of Collateral Agent and 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

                                       -46-

<PAGE>

either Collateral Agent or 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
either Collateral Agent or 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
either Collateral Agent or Lender; (iii) failure by either Collateral Agent or
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 either Collateral Agent's 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 Collateral Agent's or 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 Collateral
Agent and Lender), protect, indemnify and hold harmless Collateral Agent and
Lender, each affiliate or subsidiary of Collateral Agent and/or Lender, and each
of their respective officers, directors, employees, attorneys and 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

                                       -47-

<PAGE>

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 Collateral Agent or Lender shall be sent

Milwaukee, Wisconsin 53214, attention: Dale Grzenia, facsimile number: (414)

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

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

                                       -48-

<PAGE>

or remaining provisions of this Agreement.

     To induce Collateral Agent and Lender to accept this Agreement, each
Borrower irrevocably agrees that, subject to Collateral Agent's and 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 irrevocably appoints and designates
the Secretary of State of Illinois, whose address is Springfield, Illinois (or
any other person having and maintaining a place of business in such state whom
such Borrower may from time to time hereafter designate upon ten (10) days
written notice to Collateral Agent and Lender and whom Collateral Agent and
Lender have agreed in their sole discretion in writing is satisfactory and who
has executed an agreement in form and substance satisfactory to Collateral Agent
and Lender agreeing to act as such attorney and agent), as such Borrower's true
and lawful attorney and duly authorized agent for acceptance of service of legal
process; provided that Collateral Agent and/or Lender first diligently attempt
to serve such Borrower. Each Borrower agrees that service of such process upon
such person shall constitute personal service of such process upon such
Borrower. 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 limitation, such Borrower's rights, titles,
interest, remedies, powers or duties hereunder and thereunder. Each Borrower
hereby consents to Collateral Agent's and 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, Collateral Agent's and Lender's rights,
titles, interest, remedies, powers and/or duties and agrees that it shall
execute and deliver such documents as Collateral Agent and Lender may request in
connection with any such sale, assignment, transfer or other disposition.

<PAGE>

     24. POWER OF ATTORNEY.

     Each Borrower acknowledges and agrees that its appointment of each of
Collateral Agent and Lender as its attorney and agent-in-fact for the purposes

be irrevocable until all of the Liabilities are satisfied and paid in full and
this Agreement is terminated.

     25. CONFIDENTIALITY.

such Borrower to Collateral Agent or Lender (or to any affiliate of Collateral
Agent or Lender); and (ii) non-public, confidential or proprietary in nature,
shall be kept confidential by Collateral Agent and 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
Collateral Agent or Lender or such affiliate to Collateral Agent's or Lender's
or such affiliate's directors, officers, employees, attorneys, affiliates,
assignees, participants (provided such assignees and/or participants have agreed
to keep such information confidential to the extent provided in this Section
25), auditors, agents and regulators, and upon the order of a court or other
governmental agency having jurisdiction over Collateral Agent or Lender or such
affiliate, to any other party. Each Borrower, Collateral Agent and Lender
further agree that this provision shall survive the termination of this
Agreement. Notwithstanding the foregoing, each Borrower hereby consents to

     26. COUNTERPARTS.

     This Agreement 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; provided, that if Borrowers' computer systems are
unable to produce such documents in Approved Electronic Form, Borrowers shall
not be required to do so; provided, further, Borrowers shall cooperate with
Lender in attempting to enable Borrowers' computer systems to produce such
documents in Approved Electronic Form. For purposes hereof "Electronic Form"
means e-mail, e-mail attachments, data submitted on web-based forms or any other
communication

                                       -50-

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, COLLATERAL AGENT 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 COLLATERAL AGENT AND/OR LENDER. IN NO EVENT SHALL
COLLATERAL AGENT OR LENDER BE LIABLE FOR LOST PROFITS OR OTHER SPECIAL 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.

     (c) Each Borrower hereby waives the benefit of any law that would otherwise
restrict or limit Collateral Agent or Lender or any affiliate of Collateral
Agent or 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 Collateral Agent or
Lender or such affiliate of Collateral Agent or Lender to Borrower, including,
without limitation any deposit account at Collateral Agent or Lender or such
affiliate.

     (d) EACH BORROWER HEREBY WAIVES ALL RIGHTS TO NOTICE AND HEARING OF ANY
KIND PRIOR TO THE EXERCISE BY COLLATERAL AGENT OF ITS RIGHTS TO REPOSSESS THE
COLLATERAL OF SUCH BORROWER WITHOUT JUDICIAL PROCESS OR TO REPLEVY, ATTACH OR
LEVY UPON SUCH COLLATERAL.

     (e) Collateral Agent's or 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
Collateral Agent or Lender thereafter to demand strict compliance and
performance therewith. Any suspension or waiver by Collateral Agent or 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,

                                       -51-

<PAGE>

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 Collateral Agent or 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
Collateral Agent or Lender unless such suspension or waiver is in writing,
