the order of MLBFS, at the times and in the manner set forth in this Loan
Agreement, or in such other manner and at such place as MLBFS may hereafter
designate in writing, the following: (a) on the Maturity Date, or if earlier, on
the date of termination of the WCMA Line of Credit, the WCMA Loan Balance; (b)
interest at the Interest Rate (or, if applicable, at the Default Interest Rate)
on the outstanding WCMA Loan Balance, from and including the date on which the
initial WCMA Loan is made until the date of payment of all WCMA Loans in full;
and (c) on demand, all other sums payable pursuant to this Loan Agreement,
including, but not limited to, the periodic Line Fee. Except as otherwise

Agreement.

2.2 WCMA LOANS

(a) ACTIVATION DATE. Provided that: (i) the Commitment Expiration Date shall not
then have occurred, and (ii) Customer shall have subscribed to the WCMA Program
and its subscription to the WCMA Program shall then be in effect, the Activation
Date shall occur on or promptly after the date, following the acceptance of this


                                       3
<PAGE>
Loan Agreement by MLBFS at its office in Chicago, Illinois, upon which each of
the General Funding Conditions shall have been met or satisfied to the
reasonable satisfaction of MLBFS. No activation by MLBFS of the WCMA Line of
Credit for a nominal amount shall be deemed evidence of the satisfaction of any
of the conditions herein set forth, or a waiver of any of the terms or
conditions hereof. Customer hereby authorizes MLBFS to pay out of and charge to
Customer's WCMA Account on the Activation Date any and all amounts necessary to
fully pay off any bank or other financial institution having a lien upon any of
the Collateral other than a Permitted Lien.

(b) WCMA LOANS. Subject to the terms and conditions hereof, during the period
from and after the Activation Date to the first to occur of the Maturity Date or
the date of termination of the WCMA Line of Credit pursuant to the terms hereof,
and in addition to WCMA Loans automatically made to pay accrued interest, as
hereafter provided: (i) MLBFS will make WCMA Loans to Customer in such amounts
as Customer may from time to time request in accordance with the terms hereof,
up to an aggregate outstanding amount not to exceed the Maximum WCMA Line of
Credit, and (ii) Customer may repay any WCMA Loans in whole or in part at
anytime, and request a re-borrowing of amounts repaid on a revolving basis.
Customer may request such WCMA Loans by use of WCMA Checks, FTS, Visa(R)
charges, wire transfers, or such other means of access to the WCMA Line of
Credit as may be permitted by MLBFS from time to time; it being understood that
so long as the WCMA Line of Credit shall be in effect, any charge or debit to
the WCMA Account which but for the WCMA Line of Credit would under the terms of
the WCMA Agreement result in an overdraft, shall be deemed a request by Customer
for a WCMA Loan.

(c) CONDITIONS OF WCMA LOANS. Notwithstanding the foregoing, MLBFS shall not be
obligated to make any WCMA Loan, and may without notice refuse to honor any such
request by Customer, if at the time of receipt by MLBFS of Customer's request
(i) the making of such WCMA Loan would cause the Maximum WCMA Line of Credit to
be exceeded; or (ii) the Maturity Date shall have occurred, or the WCMA Line of
Credit shall have otherwise been terminated in accordance with the terms hereof;
or (iii) Customer's subscription to the WCMA Program shall have been terminated;
or (iv) an event shall have occurred and be continuing which shall have caused
any of the General Funding Conditions to not then be met or satisfied to the
reasonable satisfaction of MLBFS. The making by MLBFS of any WCMA Loan at a time
when any one or more of said conditions shall not have been met shall not in any
event be construed as a waiver of said condition or conditions or of any
Default, and shall not prevent MLBFS at any time thereafter while any condition
shall not have been met from refusing to honor any request by Customer for a
WCMA Loan.

(d) LIMITATION OF LIABILITY. MLBFS shall not be responsible, and shall have no
liability to Customer or any other party, for any delay or failure of MLBFS to
honor any request of Customer for a WCMA Loan or any other act or omission of
MLBFS, MLPF&S or any of their affiliates due to or resulting from any system
failure, error or delay in posting or other clerical error, loss of power, fire,
Act of God or other cause beyond the reasonable control of MLBFS, MLPF&S or any
of their affiliates unless directly arising out of the willful wrongful act or
active gross negligence of MLBFS. In no event shall MLBFS be liable to Customer
or any other party for any incidental or consequential damages arising from any
act or omission by MLBFS, MLPF&S or any of their affiliates in connection with
the WCMA Line of Credit or this Loan Agreement.

(e) INTEREST. (i) An amount equal to accrued interest on the WCMA Loan Balance
shall be payable by Customer monthly on each Interest Due Date, commencing with
the Interest Due Date occurring in the calendar month in which the Activation
Date shall occur. Unless otherwise hereafter directed in writing by MLBFS on or
after the first to occur of the Maturity Date or the date of termination of the
WCMA Line of Credit pursuant to the terms hereof, such interest will be
automatically charged to the WCMA Account on the applicable Interest Due Date,
and, to the extent not paid with free credit balances or the proceeds of sales
of any Money Accounts then in the WCMA Account, as hereafter provided, paid by a
WCMA Loan and added to the WCMA Loan Balance. All interest shall be computed for
the actual number of days elapsed on the basis of a year consisting of 360 days.

(ii) Upon the occurrence and during the continuance of any Default, but without
limiting the rights and remedies otherwise available to MLBFS hereunder or
waiving such Default, the interest payable by Customer hereunder shall at the
option of MLBFS accrue and be payable at the Default Interest Rate. The Default
Interest Rate, once implemented, shall continue to apply to the Obligations
under this Loan Agreement and be payable by Customer until the date such Default
is either cured or waived in writing by MLBFS.

(iii) Notwithstanding any provision to the contrary in this Agreement or any of
the Additional Agreements, no provision of this Agreement or any of the
Additional Agreements shall require the payment or permit the collection of any
amount in excess of the maximum amount of interest permitted to be charged by
law ("Excess Interest"). If any Excess Interest is provided for, or is
adjudicated as being provided for, in this Agreement or any of the Additional
Agreements, then: (A) Customer shall not be obligated to pay any Excess
Interest; and (B) any Excess Interest that MLBFS may have received hereunder or
under any of the Additional Agreements shall, at the option of MLBFS, be: (1)
applied as a credit against the then unpaid WCMA Loan Balance, (2) refunded to
the payer thereof, or (3) any combination of the foregoing.

(f) PAYMENTS. All payments required or permitted to be made pursuant to this
Loan Agreement shall be made in lawful money of the United States. Unless
otherwise directed by MLBFS, payments on account of the WCMA Loan Balance may be
made by the delivery of checks (other than WCMA Checks), or by means of FTS or
wire transfer of funds (other than funds from the WCMA Line of Credit) to MLPF&S
for credit to Customer's WCMA Account. Notwithstanding anything in the WCMA
Agreement to the contrary, Customer hereby irrevocably authorizes and directs
MLPF&S to apply available free credit balances in the WCMA Account to the
repayment of the WCMA Loan Balance prior to application for any other purpose.
Payments to MLBFS from funds in the WCMA Account shall be deemed to be made by
Customer upon the same basis and schedule as funds are made available for
investment in the Money Accounts in accordance with the terms of the WCMA
Agreement. All funds received by MLBFS from MLPF&S pursuant to the aforesaid
authorization shall be applied by MLBFS to repayment of the WCMA Loan Balance.
The acceptance by or on behalf of MLBFS of a check or other payment for a lesser
amount than shall be due from Customer, regardless of any endorsement or
statement thereon or transmitted therewith, shall not be deemed an accord and
satisfaction or anything other than a payment on account, and MLBFS or anyone
acting on behalf of MLBFS may accept such check or other payment without
prejudice to the rights of MLBFS to recover the balance actually due or to
pursue any other remedy under this Loan Agreement or applicable law for such
balance. All checks accepted by or on behalf of MLBFS in connection with the
WCMA Line of Credit are subject to final collection.

(g) IRREVOCABLE INSTRUCTIONS TO MLPF&S. In order to minimize the WCMA Loan
Balance, Customer hereby irrevocably authorizes and directs MLPF&S, effective on
the Activation Date and continuing thereafter so long as this Agreement shall be
in effect: (i) to immediately and prior to application for any other purpose pay
to MLBFS to the extent of any WCMA Loan Balance or other amounts payable by
Customer hereunder all available free credit balances from time to time in the
WCMA Account; and (ii) if such available free credit balances are insufficient
to pay the WCMA Loan Balance and such other amounts, and there are in the WCMA
Account at any time any investments in Money Accounts (other than any
investments constituting any Minimum Money Accounts Balance under the WCMA
Directed Reserve Program), to immediately liquidate such investments and pay to
MLBFS to the extent of any WCMA Loan Balance and such other amounts the
available proceeds from the liquidation of any such Money Accounts.

(h) STATEMENTS. MLPF&S will include in each monthly statement it issues under
the WCMA Program information with respect to WCMA Loans and the WCMA Loan
Balance. Any questions that Customer may have with respect to such information
should be directed to MLBFS; and any questions with respect to any other matter
in such statements or about or affecting the WCMA Program should be directed to
MLPF&S.

(i) USE OF WCMA LOAN PROCEEDS. The proceeds of each WCMA Loan initiated by
Customer shall be used by Customer solely for working capital in the ordinary
course of its business, or, with the prior written consent of MLBFS, for other
lawful business purposes of Customer not prohibited hereby. CUSTOMER AGREES THAT
UNDER NO CIRCUMSTANCES WILL THE PROCEEDS OF ANY WCMA LOAN BE USED: (I) FOR
PERSONAL, FAMILY OR HOUSEHOLD PURPOSES OF ANY PERSON WHATSOEVER, OR (II) TO
PURCHASE, CARRY OR TRADE IN SECURITIES, OR REPAY DEBT INCURRED TO PURCHASE,
CARRY OR TRADE IN SECURITIES, WHETHER IN OR IN CONNECTION WITH THE WCMA ACCOUNT,
ANOTHER ACCOUNT OF CUSTOMER WITH MLPF&S OR AN ACCOUNT OF CUSTOMER AT ANY OTHER
BROKER OR DEALER IN SECURITIES, OR (III) UNLESS OTHERWISE CONSENTED TO IN
WRITING BY MLBFS, TO PAY ANY AMOUNT TO MERRILL LYNCH AND CO., INC. OR ANY OF ITS
SUBSIDIARIES, OTHER THAN MERRILL LYNCH BANK USA, MERRILL LYNCH BANK & TRUST CO.
OR ANY SUBSIDIARY OF EITHER OF THEM (INCLUDING MLBFS AND MERRILL LYNCH CREDIT
CORPORATION).

                                       5
<PAGE>
(j) RENEWAL AT OPTION OF MLBFS; RIGHT OF CUSTOMER TO TERMINATE. MLBFS may at any
time, in its sole discretion and at its sole option, renew the WCMA Line of
Credit for one or more Renewal Years; it being understood, however, that no such
renewal shall be effective unless set forth in a writing executed by a duly
authorized representative of MLBFS and delivered to Customer. Unless any such
renewal is accompanied by a proposed change in the terms of the WCMA Line of
Credit (other than the extension of the Maturity Date), no such renewal shall
require Customer's approval. Customer shall, however, have the right to
terminate the WCMA Line of Credit at any time upon written notice to MLBFS.

(k) LINE FEES. (i) In consideration of the extension of the WCMA Line of Credit
by MLBFS to Customer during the period from the Activation Date to the Initial
Maturity Date, Customer has paid or shall pay the Line Fee to MLBFS. If the Line
Fee has not heretofore been paid by Customer, Customer hereby authorizes MLBFS,
at its option, to either cause the Line Fee to be paid on the Activation Date
with a WCMA Loan, or invoice Customer for such Line Fee (in which event Customer
shall pay said fee within 5 Business Days after receipt of such invoice). No
delay in the Activation Date, howsoever caused, shall entitle Customer to any
rebate or reduction in the Line Fee or to any extension of the Initial Maturity
Date.

(ii) Customer shall pay an additional Line Fee for each Renewal Year. In
connection therewith, Customer hereby authorizes MLBFS, at its option, to either
cause each such additional Line Fee to be paid with a WCMA Loan on or at any
time after the first Business Day of such Renewal Year or invoiced to Customer
at such time (in which event Customer shall pay such Line Fee within 5 Business
Days after receipt of such invoice). Each Line Fee shall be deemed fully earned
by MLBFS on the date payable by Customer, and no termination of the WCMA Line of
Credit, howsoever caused, shall entitle Customer to any rebate or refund of any
portion of such Line Fee; provided, however, that if Customer shall terminate
the WCMA Line of Credit not later than 5 Business Days after the receipt by
Customer of notice from MLBFS of a renewal of the WCMA Line of Credit, Customer
shall be entitled to a refund of any Line Fee charged by MLBFS for the ensuing
Renewal Year.

the financial statements heretofore furnished to MLBFS, or prepared on such
other basis as may be approved in writing by MLBFS; and (ii) permit MLBFS or its
duly authorized representatives, upon reasonable notice and at reasonable times,
to inspect its properties (both real and personal), operations, books and
records.

(b) TAXES. Customer and each Guarantor will pay when due all taxes, assessments
and other governmental charges, howsoever designated, and all other liabilities
and obligations, except to the extent that any such failure to pay will not
materially and adversely affect either the liens and security interests of MLBFS
hereunder or under any of the Additional Agreements, the financial condition of
Customer or any Guarantor or the continued operations of Customer or any
Business Guarantor.

(c) COMPLIANCE WITH LAWS AND AGREEMENTS. Neither Customer nor any Guarantor will
violate any law, regulation or other governmental requirement, any judgment or
order of any court or governmental agency or authority, or any agreement,
instrument or document to which it is a party or by which it is bound, if any
such violation will materially and adversely affect either the liens and
security interests of MLBFS hereunder or under any of the Additional Agreements,
the financial condition of Customer or any Guarantor, or the continued
operations of Customer or any Business Guarantor.

(d) NO USE OF MERRILL LYNCH NAME. Neither Customer nor any Guarantor will
directly or indirectly publish, disclose or otherwise use in any advertising or
promotional material, or press release or interview, the name, logo or any
trademark of MLBFS, MLPF&S, Merrill Lynch and Co., Incorporated or any of their
affiliates.

(e) NOTIFICATION BY CUSTOMER. Customer shall provide MLBFS with prompt written
notification of: (i) any Default; (ii) any materially adverse change in the
business, financial condition or operations of Customer or any Business
Guarantor; (iii) any information which indicates that any financial statements
of Customer or any Guarantor fail in any material respect to present fairly the
financial condition and results of operations purported to be presented in such


                                       8
<PAGE>
statements; and (iv) any change in Customer's outside accountants. Each
notification by Customer pursuant hereto shall specify the event or information
causing such notification, and, to the extent applicable, shall specify the
steps being taken to rectify or remedy such event or information.

(f) NOTICE OF CHANGE. Customer shall give MLBFS not less than 30 days prior
written notice of any change in the name (including any fictitious name) or
principal place of business or residence of Customer or any Guarantor.

(g) CONTINUITY. Except upon the prior written consent of MLBFS, which consent
will not be unreasonably withheld: (i) neither Customer nor any Business
Guarantor shall be a party to any merger or consolidation with, or purchase or
otherwise acquire all or substantially all of the assets of, or any material
stock, partnership, joint venture or other equity interest in, any person or
entity, or sell, transfer or lease all or any substantial part of its assets, if
any such action would result in either: (A) a material change in the principal
business, ownership or control of Customer or such Business Guarantor, or (B) a
material adverse change in the financial condition or operations of Customer or
such Business Guarantor; (ii) Customer and each Business Guarantor shall
preserve their respective existence and good standing in the jurisdiction(s) of
establishment and operation; (iii) neither Customer nor any Business Guarantor
shall engage in any material business substantially different from their
respective business in effect as of the date of application by Customer for
credit from MLBFS, or cease operating any such material business; (iv) neither
Customer nor any Business Guarantor shall cause or permit any other person or
entity to assume or succeed to any material business or operations of Customer
or such Business Guarantor; and (v) neither Customer nor any Business Guarantor
shall cause or permit any material change in its controlling ownership.

(h) MINIMUM TANGIBLE NET WORTH. Customer's and Business Guarantor's aggregate
"tangible net worth" shall at all times exceed $5,000,000.00. For the purposes
hereof, the term "tangible net worth" shall mean Customer's and Business
Guarantor's aggregate net worth as shown on their regular financial statements
prepared in a manner consistent with the terms hereof, but excluding an amount
equal to (i) any assets which are ordinarily classified as "intangible" in
accordance with generally accepted accounting principles, and (ii) any amounts
now or hereafter directly or indirectly owing to Customer or Business Guarantor
by officers, shareholders or affiliates of Customer or Business Guarantor.

(i) MINIMUM WORKING CAPITAL. Customer's and Business Guarantor's aggregate net
working capital (i.e. the excess of its current assets over its current
liabilities), as shown on their regular books and records, shall at all time
exceed $5,000,000.00.

(j) OPERATING PROFITS. As of the close of the quarter ending September 30, 2001,
Customer shall generate a pre-tax profit from operations as demonstrated by the
quarterly financial statements required hereby.

3.4 COLLATERAL

(a) PLEDGE OF COLLATERAL. To secure payment and performance of the Obligations,
Customer hereby pledges, assigns, transfers and sets over to MLBFS, and grants
to MLBFS first liens and security interests in and upon all of the Collateral,
subject only to Permitted Liens.

(b) LIENS. Except upon the prior written consent of MLBFS, Customer shall not
create or permit to exist any lien, encumbrance or security interest upon or
with respect to any Collateral now owned or hereafter acquired other than
Permitted Liens.

(c) PERFORMANCE OF OBLIGATIONS. Customer shall perform all of its obligations
owing on account of or with respect to the Collateral; it being understood that
nothing herein, and no action or inaction by MLBFS, under this Loan Agreement or
otherwise, shall be deemed an assumption by MLBFS of any of Customer's said
obligations.

(d) SALES AND COLLECTIONS. So long as no Event of Default shall have occurred
and be continuing, Customer may in the ordinary course of its business: (i) sell
any Inventory normally held by Customer for sale, (ii) use or consume any
materials and supplies normally held by Customer for use or consumption, and
(iii) collect all of its Accounts. Customer shall take such action with respect


                                       9
<PAGE>
to protection of its Inventory and the other Collateral and the collection of
its Accounts as MLBFS may from time to time reasonably request.

(e) ACCOUNT SCHEDULES. Upon the request of MLBFS, made now or at any reasonable
time or times hereafter, Customer shall deliver to MLBFS, in addition to the
other information required hereunder, a schedule identifying, for each Account
and all Chattel Paper subject to MLBFS' security interests hereunder, each
Account Debtor by name and address and amount, invoice or contract number and
date of each invoice or contract. Customer shall furnish to MLBFS such
additional information with respect to the Collateral, and amounts received by
Customer as proceeds of any of the Collateral, as MLBFS may from time to time
reasonably request.

(f) ALTERATIONS AND MAINTENANCE. Except upon the prior written consent of MLBFS,
Customer shall not make or permit any material alterations to any tangible
Collateral which might materially reduce or impair its market value or utility.
Customer shall at all times keep the tangible Collateral in good condition and
repair, reasonable wear and tear excepted, and shall pay or cause to be paid all
obligations arising from the repair and maintenance of such Collateral, as well
as all obligations with respect to any Location of Tangible Collateral, except
for any such obligations being contested by Customer in good faith by
appropriate proceedings.

(g) LOCATION. Except for movements required in the ordinary course of Customer's
business, Customer shall give MLBFS 30 days' prior written notice of the placing
at or movement of any tangible Collateral to any location other than a Location
of Tangible Collateral. In no event shall Customer cause or permit any material
tangible Collateral to be removed from the United States without the express
prior written consent of MLBFS.

(h) INSURANCE. Customer shall insure all of the tangible Collateral under a
policy or policies of physical damage insurance providing that losses will be
payable to MLBFS as its interests may appear pursuant to a Lender's Loss Payable
Endorsement and containing such other provisions as may be reasonably required
by MLBFS. Customer shall further provide and maintain a policy or policies of
comprehensive public liability insurance naming MLBFS as an additional party
insured. Customer and each Business Guarantor shall maintain such other
insurance as may be required by law or is customarily maintained by companies in
a similar business or otherwise reasonably required by MLBFS. All such insurance
policies shall provide that MLBFS will receive not less than 10 days, prior
written notice of any cancellation, and shall otherwise be in form and amount
and with an insurer or insurers reasonably acceptable to MLBFS. Customer shall
furnish MLBFS with a copy or certificate of each such policy or policies and,
prior to any expiration or cancellation, each renewal or replacement thereof.

(i) EVENT OF LOSS. Customer shall at its expense promptly repair all repairable
damage to any tangible Collateral. In the event that any tangible Collateral is
damaged beyond repair, lost, totally destroyed or confiscated (an "Event of
Loss") and such Collateral had a value prior to such Event of Loss of $25,000.00
or more, then, on or before the first to occur of (i) 90 days after the
occurrence of such Event of Loss, or (ii) 10 Business Days after the date on
which either Customer or MLBFS shall receive any proceeds of insurance on
account of such Event of Loss, or any underwriter of insurance on such
Collateral shall advise either Customer or MLBFS that it disclaims liability in
respect of such Event of Loss, Customer shall, at Customer's option, either
replace the Collateral subject to such Event of Loss with comparable Collateral
free of all liens other than Permitted Liens (in which event Customer shall be
entitled to utilize the proceeds of insurance on account of such Event of Loss
for such purpose, and may retain any excess proceeds of such insurance), or
deposit into the WCMA Account an amount equal to the actual cash value of such
Collateral as determined by either the insurance company's payment (plus any
applicable deductible) or, in absence of insurance company payment, as
reasonably determined by MLBFS; it being further understood that any such
deposit shall be accompanied by a like permanent reduction in the Maximum WCMA
Line of Credit. Notwithstanding the foregoing, if at the time of occurrence of
such Event of Loss or any time thereafter prior to replacement or line
reduction, as aforesaid, an Event of Default shall have occurred and be
continuing hereunder, then MLBFS may at its sole option, exercisable at any time
while such Event of Default shall be continuing, require Customer to either
replace such Collateral or make a deposit into the WCMA Account and reduce the
Maximum WCMA Line of Credit, as aforesaid.

(j) NOTICE OF CERTAIN EVENTS. Customer shall give MLBFS immediate notice of any
attachment, lien, judicial process, encumbrance or claim affecting or involving
$25,000.00 or more of the Collateral.


                                       10
<PAGE>
(k) INDEMNIFICATION. Customer shall indemnify, defend and save MLBFS harmless
from and against any and all claims, liabilities, losses, costs and expenses
(including, without limitation, reasonable attorneys' fees and expenses) of any
nature whatsoever which may be asserted against or incurred by MLBFS arising out
of or in any manner occasioned by (i) the ownership, collection, possession, use
or operation of any Collateral, or (ii) any failure by Customer to perform any
of its obligations hereunder; excluding, however, from said indemnity any such
claims, liabilities, etc. arising directly out of the willful wrongful act or
active gross negligence of MLBFS. This indemnity shall survive the expiration or
termination of this Loan Agreement as to all matters arising or accruing prior
to such expiration or termination.

3.5 EVENTS OF DEFAULT

The occurrence of any of the following events shall constitute an "Event of
Default" under this Loan Agreement:

(a) EXCEEDING THE MAXIMUM WCMA LINE OF CREDIT. If the WCMA Loan Balance shall at
any time exceed the Maximum WCMA Line of Credit and Customer shall fail to
deposit sufficient funds into the WCMA Account to reduce the WCMA Loan Balance
below the Maximum WCMA Line of Credit within five (5) Business Days after
written notice thereof shall have been given by MLBFS to Customer.

(b) OTHER FAILURE TO PAY. Customer shall fail to pay to MLBFS or deposit into
the WCMA Account when due any other amount owing or required to be paid or
deposited by Customer under this Loan Agreement, or shall fail to pay when due
any other Obligations, and any such failure shall continue for more than five
(5) Business Days after written notice thereof shall have been given by MLBFS to
Customer.

(c) FAILURE TO PERFORM. Customer or any Guarantor shall default in the
performance or observance of any covenant or agreement on its part to be
performed or observed under this Loan Agreement or any of the Additional
Agreements (not constituting an Event of Default under any other clause of this
Section), and such default shall continue unremedied for ten (10) Business Days
after written notice thereof shall have been given by MLBFS to Customer.

(d) BREACH OF WARRANTY. Any representation or warranty made by Customer or any
Guarantor contained in this Loan Agreement or any of the Additional Agreements
shall at any time prove to have been incorrect in any material respect when
made.

(e) DEFAULT UNDER OTHER AGREEMENT. A default or Event of Default by Customer or
any Guarantor shall occur under the terms of any other agreement, instrument or
document with or intended for the benefit of MLBFS, MLPF&S or any of their
affiliates, and any required notice shall have been given and required passage
of time shall have elapsed.

(f) BANKRUPTCY EVENT. Any Bankruptcy Event shall occur.

(g) MATERIAL IMPAIRMENT. Any event shall occur which shall reasonably cause
MLBFS to in good faith believe that the prospect of full payment or performance
by Customer or any Guarantor of any of their respective liabilities or
obligations under this Loan Agreement or any of the Additional Agreements to
which Customer or such Guarantor is a party has been materially impaired. The
existence of such a material impairment shall be determined in a manner
consistent with the intent of Section 1-208 of the UCC.

(h) ACCELERATION OF DEBT TO OTHER CREDITORS. Any event shall occur which results
in the acceleration of the maturity of any indebtedness of $100,000.00 or more
of Customer or any Guarantor to another creditor under any indenture, agreement,
undertaking, or otherwise.

(i) SEIZURE OR ABUSE OF COLLATERAL. The Collateral, or any material part
thereof, shall be or become subject to any material abuse or misuse, or any
levy, attachment, seizure or confiscation which is not released within ten (10)
Business Days.

                                       11

3.6 REMEDIES

(a) REMEDIES UPON DEFAULT. Upon the occurrence and during the continuance of any
Event of Default, MLBFS may at its sole option do any one or more or all of the
following, at such time and in such order as MLBFS may in its sole discretion
choose:

(i) TERMINATION. MLBFS may without notice terminate the WCMA Line of Credit and
all obligations to provide the WCMA Line of Credit or otherwise extend any
credit to or for the benefit of Customer (it being understood, however, that
upon the occurrence of any Bankruptcy Event the WCMA Line of Credit and all such
obligations shall automatically terminate without any action on the part of
MLBFS); and upon any such termination MLBFS shall be relieved of all such
obligations.

(ii) ACCELERATION. MLBFS may declare the principal of and interest on the WCMA
Loan Balance, and all other Obligations to be forthwith due and payable,
whereupon all such amounts shall be immediately due and payable, without
presentment, demand for payment, protest and notice of protest, notice of
dishonor, notice of acceleration, notice of intent to accelerate or other notice
or formality of any kind, all of which are hereby expressly waived; provided,
however, that upon the occurrence of any Bankruptcy Event all such principal,
interest and other Obligations shall automatically become due and payable
without any action on the part of MLBFS.

(iii) EXERCISE OTHER RIGHTS. MLBFS may exercise any or all of the remedies of a
secured party under applicable law, including, but not limited to, the UCC, and
any or all of its other rights and remedies under this Loan Agreement and the
Additional Agreements.

(iv) POSSESSION. MLBFS may require Customer to make the Collateral and the
records pertaining to the Collateral available to MLBFS at a place designated by
MLBFS which is reasonably convenient to Customer, or may take possession of the
Collateral and the records pertaining to the Collateral without the use of any
judicial process and without any prior notice to Customer.

(v) SALE. MLBFS may sell any or all of the Collateral at public or private sale
upon such terms and conditions as MLBFS may reasonably deem proper. MLBFS may
purchase any Collateral at any such public sale. The net proceeds of any such
public or private sale and all other amounts actually collected or received by
MLBFS pursuant hereto, after deducting all costs and expenses incurred at any
time in the collection of the Obligations and in the protection, collection and
sale of the Collateral, will be applied to the payment of the Obligations, with
any remaining proceeds paid to Customer or whoever else may be entitled thereto,
and with Customer and each Guarantor remaining jointly and severally liable for
any amount remaining unpaid after such application.

(vi) DELIVERY OF CASH, CHECKS, ETC. MLBFS may require Customer to forthwith upon
receipt, transmit and deliver to MLBFS in the form received, all cash, checks,
drafts and other instruments for the payment of money (properly endorsed, where
required, so that such items may be collected by MLBFS) which may be received by
Customer at any time in full or partial payment of any Collateral, and require
that Customer not commingle any such items which may be so received by Customer
with any other of its funds or property but instead hold them separate and apart
and in trust for MLBFS until delivery is made to MLBFS.

(vii) NOTIFICATION OF ACCOUNT DEBTORS. MLBFS may notify any Account Debtor that
its Account or Chattel Paper has been assigned to MLBFS and direct such Account
Debtor to make payment directly to MLBFS of all amounts due or becoming due with
respect to such Account or Chattel Paper; and MLBFS may enforce payment and
collect, by legal proceedings or otherwise, such Account or Chattel Paper.

(viii) CONTROL OF COLLATERAL. MLBFS may otherwise take control in any lawful
manner of any cash or non-cash items of payment or proceeds of Collateral and of
any rejected, returned, stopped in transit or repossessed goods included in the
Collateral and endorse Customer's name on any item of payment on or proceeds of
the Collateral.

(b) SET-OFF. MLBFS shall have the further right upon the occurrence and during
the continuance of an Event of Default to set-off, appropriate and apply toward
payment of any of the Obligations, in such order of application as MLBFS may


                                       12
<PAGE>
from time to time and at any time elect, any cash, credit, deposits, accounts,
financial assets, investment property, securities and any other property of
Customer which is in transit to or in the possession, custody or control of
MLBFS, MLPF&S or any agent, bailee, or affiliate of MLBFS or MLPF&S. Customer
hereby collaterally assigns and grants to MLBFS a continuing security interest
in all such property as additional Collateral.

(c) POWER OF ATTORNEY. Effective upon the occurrence and during the continuance
of an Event of Default, Customer hereby irrevocably appoints MLBFS as its
attorney-in-fact, with full power of substitution, in its place and stead and in
its name or in the name of MLBFS, to from time to time in MLBFS' sole discretion
take any action and to execute any instrument which MLBFS may deem necessary or
advisable to accomplish the purposes of this Loan Agreement, including, but not
limited to, to receive, endorse and collect all checks, drafts and other
instruments for the payment of money made payable to Customer included in the
Collateral.

(d) REMEDIES ARE SEVERABLE AND CUMULATIVE. All rights and remedies of MLBFS
herein are severable and cumulative and in addition to all other rights and
remedies available in the Additional Agreements, at law or in equity, and any
one or more of such rights and remedies may be exercised simultaneously or
successively.

(e) NOTICES. To the fullest extent permitted by applicable law, Customer hereby
irrevocably waives and releases MLBFS of and from any and all liabilities and
penalties for failure of MLBFS to comply with any statutory or other requirement
imposed upon MLBFS relating to notices of sale, holding of sale or reporting of
any sale, and Customer waives all rights of redemption or reinstatement from any
such sale. Any notices required under applicable law shall be reasonably and
properly given to Customer if given by any of the methods provided herein at
least 5 Business Days prior to taking action. MLBFS shall have the right to
postpone or adjourn any sale or other disposition of Collateral at any time
without giving notice of any such postponed or adjourned date. In the event
MLBFS seeks to take possession of any or all of the Collateral by court process,
Customer further irrevocably waives to the fullest extent permitted by law any
bonds and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession, and any demand for
possession prior to the commencement of any suit or action.

3.7 MISCELLANEOUS

(a) NON-WAIVER. No failure or delay on the part of MLBFS in exercising any
right, power or remedy pursuant to this Loan Agreement or any of the Additional
Agreements shall operate as a waiver thereof, and no single or partial exercise
of any such right, power or remedy shall preclude any other or further exercise
thereof, or the exercise of any other right, power or remedy. Neither any waiver
of any provision of this Loan Agreement or any of the Additional Agreements, nor
any consent to any departure by Customer therefrom, shall be effective unless
the same shall be in writing and signed by MLBFS. Any waiver of any provision of
this Loan Agreement or any of the Additional Agreements and any consent to any
departure by Customer from the terms of this Loan Agreement or any of the
Additional Agreements shall be effective only in the specific instance and for
the specific purpose for which given. Except as otherwise expressly provided
herein, no notice to or demand on Customer shall in any case entitle Customer to
any other or further notice or demand in similar or other circumstances.

(b) DISCLOSURE. Customer hereby irrevocably authorizes MLBFS and each of its
affiliates, including without limitation MLPF&S, to at any time (whether or not
an Event of Default shall have occurred) obtain from and disclose to each other
any and all financial and other information about Customer. In connection with
said authorization, the parties recognize that in order to provide a WCMA Line
of Credit certain information about Customer is required to be made available on
a computer network accessible by certain affiliates of MLBFS, including MLPF&S.

(c) COMMUNICATIONS. All notices and other communications required or permitted
hereunder shall be in writing, and shall be either delivered personally, mailed
by postage prepaid certified mail or sent by express overnight courier or by
facsimile. Such notices and communications shall be deemed to be given on the
date of personal delivery, facsimile transmission or actual delivery of
certified mail, or one Business Day after delivery to an express overnight
courier. Unless otherwise specified in a notice sent or delivered in accordance
with the terms hereof, notices and other communications in writing shall be


                                       13
<PAGE>
given to the parties hereto at their respective addresses set forth at the
beginning of this Loan Agreement, or, in the case of facsimile transmission, to
the parties at their respective regular facsimile telephone number.

(d) FEES, EXPENSES AND TAXES. Customer shall pay or reimburse MLBFS for (i) all
Uniform Commercial Code filing and search fees and expenses incurred by MLBFS in
connection with the verification, perfection or preservation of MLBFS' rights
hereunder or in the Collateral or any other collateral for the Obligations; (ii)
any and all stamp, transfer and other taxes and fees payable or determined to be
payable in connection with the execution, delivery and/or recording of this Loan
Agreement or any of the Additional Agreements; and (iii) all reasonable fees and
out-of-pocket expenses (including, but not limited to, reasonable fees and
expenses of outside counsel) incurred by MLBFS in connection with the collection
of any sum payable hereunder or under any of the Additional Agreements not paid
when due, the enforcement of this Loan Agreement or any of the Additional
Agreements and the protection of MLBFS' rights hereunder or thereunder,
excluding, however, salaries and normal overhead attributable to MLBFS'
employees. Customer hereby authorizes MLBFS, at its option, to either cause any
and all such fees, expenses and taxes to be paid with a WCMA Loan, or invoice
Customer therefor (in which event Customer shall pay all such fees, expenses and
taxes within 5 Business Days after receipt of such invoice). The obligations of
Customer under this paragraph shall survive the expiration or termination of
this Loan Agreement and the discharge of the other Obligations.

(e) RIGHT TO PERFORM OBLIGATIONS. If Customer shall fail to do any act or thing
which it has covenanted to do under this Loan Agreement or any representation or
warranty on the part of Customer contained in this Loan Agreement shall be
breached, MLBFS may, in its sole discretion, after 5 Business Days written
notice is sent to Customer (or such lesser notice, including no notice, as is
reasonable under the circumstances), do the same or cause it to be done or
remedy any such breach, and may expend its funds for such purpose. Any and all
reasonable amounts so expended by MLBFS shall be repayable to MLBFS by Customer
upon demand, with interest at the Interest Rate during the period from and
including the date funds are so expended by MLBFS to the date of repayment, and
all such amounts shall be additional Obligations. The payment or performance by
MLBFS of any of Customer's obligations hereunder shall not relieve Customer of
said obligations or of the consequences of having failed to pay or perform the
same, and shall not waive or be deemed a cure of any Default.

(f) FURTHER ASSURANCES. Customer agrees to do such further acts and things and
to execute and deliver to MLBFS such additional agreements, instruments and
documents as MLBFS may reasonably require or deem advisable to effectuate the
purposes of this Loan Agreement or any of the Additional Agreements, or to
establish, perfect and maintain MLBFS' security interests and liens upon the
Collateral, including, but not limited to: (i) executing financing statements or
amendments thereto when and as reasonably requested by MLBFS; and (ii) if in the
reasonable judgment of MLBFS it is required by local law, causing the owners
and/or mortgagees of the real property on which any Collateral may be located to
execute and deliver to MLBFS waivers or subordinations reasonably satisfactory
to MLBFS with respect to any rights in such Collateral.

(g) BINDING EFFECT. This Loan Agreement and the Additional Agreements shall be
binding upon, and shall inure to the benefit of, MLBFS, Customer and their
respective successors and assigns. Customer shall not assign any of its rights
or delegate any of its obligations under this Loan Agreement or any of the
Additional Agreements without the prior written consent of MLBFS. Unless
otherwise expressly agreed to in a writing signed by MLBFS, no such consent
shall in any event relieve Customer of any of its obligations under this Loan
Agreement or the Additional Agreements.

(h) HEADINGS. Captions and section and paragraph headings in this Loan Agreement
are inserted only as a matter of convenience, and shall not affect the
interpretation hereof.

(i) GOVERNING LAW. This Loan Agreement, and, unless otherwise expressly provided
therein, each of the Additional Agreements, shall be governed in all respects by
the laws of the State of Illinois.

(j) SEVERABILITY OF PROVISIONS. Whenever possible, each provision of this Loan
Agreement and the Additional Agreements shall be interpreted in such manner as
to be effective and valid under applicable law. Any provision of this Loan
Agreement or any of the Additional Agreements which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective


                                       14
<PAGE>
only to the extent of such prohibition or unenforceability without invalidating
the remaining provisions of this Loan Agreement and the Additional Agreements or
affecting the validity or enforceability of such provision in any other
jurisdiction.

(k) TERM. This Loan Agreement shall become effective on the date accepted by
MLBFS at its office in Chicago, Illinois, and, subject to the terms hereof,
shall continue in effect so long thereafter as the WCMA Line of Credit shall be
in effect or there shall be any Obligations outstanding.

(l) COUNTERPARTS. This Loan Agreement may be executed in one or more
counterparts which, when taken together, constitute one and the same agreement.

(m) JURISDICTION; WAIVER. CUSTOMER ACKNOWLEDGES THAT THIS LOAN AGREEMENT IS
BEING ACCEPTED BY MLBFS IN PARTIAL CONSIDERATION OF MLBFS' RIGHT AND OPTION, IN
ITS SOLE DISCRETION, TO ENFORCE THIS LOAN AGREEMENT (INCLUDING THE WCMA NOTE SET
FORTH HEREIN) AND THE ADDITIONAL AGREEMENTS IN EITHER THE STATE OF ILLINOIS OR
IN ANY OTHER JURISDICTION WHERE CUSTOMER OR ANY COLLATERAL FOR THE OBLIGATIONS
MAY BE LOCATED. CUSTOMER IRREVOCABLY SUBMITS ITSELF TO JURISDICTION IN THE STATE
OF ILLINOIS AND VENUE IN ANY STATE OR FEDERAL COURT IN THE COUNTY OF COOK FOR
SUCH PURPOSES, AND CUSTOMER WAIVES ANY AND ALL RIGHTS TO CONTEST SAID
JURISDICTION AND VENUE AND THE CONVENIENCE OF ANY SUCH FORUM, AND ANY AND ALL
RIGHTS TO REMOVE SUCH ACTION FROM STATE TO FEDERAL COURT. CUSTOMER FURTHER
WAIVES ANY RIGHTS TO COMMENCE ANY ACTION AGAINST MLBFS IN ANY JURISDICTION
EXCEPT IN THE COUNTY OF COOK AND STATE OF ILLINOIS. MLBFS AND CUSTOMER HEREBY
EACH EXPRESSLY WAIVE ANY AND ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES AGAINST THE OTHER
PARTY WITH RESPECT TO ANY MATTER RELATING TO, ARISING OUT OF OR IN ANY WAY
CONNECTED WITH THE WCMA LINE OF CREDIT, THIS LOAN AGREEMENT, ANY ADDITIONAL
AGREEMENTS AND/OR ANY OF THE TRANSACTIONS WHICH ARE THE SUBJECT MATTER OF THIS
LOAN AGREEMENT. CUSTOMER FURTHER WAIVES THE RIGHT TO BRING ANY NON-COMPULSORY
COUNTERCLAIMS.

(n) INTEGRATION. THIS LOAN AGREEMENT, TOGETHER WITH THE ADDITIONAL AGREEMENTS,
CONSTITUTES THE ENTIRE UNDERSTANDING AND REPRESENTS THE FULL AND FINAL AGREEMENT
BETWEEN THE PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF, AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR WRITTEN AGREEMENTS OR PRIOR, CONTEMPORANEOUS
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS OF THE PARTIES. WITHOUT LIMITING THE FOREGOING, CUSTOMER ACKNOWLEDGES
THAT EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN: (I) NO PROMISE OR COMMITMENT
HAS BEEN MADE TO IT BY MLBFS, MLPF&S OR ANY OF THEIR RESPECTIVE EMPLOYEES,
AGENTS OR REPRESENTATIVES TO EXTEND THE AVAILABILITY OF THE WCMA LINE OF CREDIT
OR THE MATURITY DATE, OR TO INCREASE THE MAXIMUM WCMA LINE OF CREDIT, OR
OTHERWISE EXTEND ANY OTHER CREDIT TO CUSTOMER OR ANY OTHER PARTY; (II) NO
PURPORTED EXTENSION OF THE MATURITY DATE, INCREASE IN THE MAXIMUM WCMA LINE OF
CREDIT OR OTHER EXTENSION OR AGREEMENT TO EXTEND CREDIT SHALL BE VALID OR
BINDING UNLESS EXPRESSLY SET FORTH IN A WRITTEN INSTRUMENT SIGNED BY MLBFS; AND
(III) THIS LOAN AGREEMENT SUPERSEDES AND REPLACES ANY AND ALL PROPOSALS, LETTERS
OF INTENT AND APPROVAL AND COMMITMENT LETTERS FROM MLBFS TO CUSTOMER, NONE OF
WHICH SHALL BE CONSIDERED AN ADDITIONAL AGREEMENT. NO AMENDMENT OR MODIFICATION
OF THIS AGREEMENT OR ANY OF THE ADDITIONAL AGREEMENTS TO WHICH CUSTOMER IS A
PARTY SHALL BE EFFECTIVE UNLESS IN A WRITING SIGNED BY BOTH MLBFS AND CUSTOMER.
