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

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
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 any
time, 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.
