such overdue amount shall bear interest, after as well as before judgment, at a
rate per annum equal to the Default Rate to the fullest extent permitted by
applicable law.
(ii)    Notwithstanding the foregoing, if an Event of Default has occurred and
is continuing and the Bank so notifies the Company (provided that no such
notification shall be required, and the following interest shall automatically
be payable, in the case of an Event of Default under Sections 15.1(a), (b), (h)
or (i)), then, so long as such Event of Default is continuing, all outstanding

past due interest) shall be due and payable upon demand.
(e)
Temporary Unavailability of LIBOR Rate. If prior to the commencement of any
LIBOR Interest Period for a LIBOR Rate Loan:

manifest error) that adequate and reasonable means do not exist for ascertaining
the LIBOR Rate for purposes of determining the Adjusted Libor Rate; or

--------------------------------------------------------------------------------

-12-

(ii)    the Bank determines (which determination shall be conclusive) that the
Adjusted LIBOR Rate will not adequately and fairly reflect the cost of making or
maintaining such Loan;

then the Bank shall give notice thereof to the Company by telephone or facsimile
as promptly as practicable thereafter and, until the Bank notifies the Company
that the circumstances giving rise to such notice no longer exist, (x) any
borrowing request that requests the continuation of any Loan as, a LIBOR Rate
Loan shall be ineffective, (y) if any borrowing request requests a LIBOR Rate
Loan, such Revolving Loan shall be made as an ABR Loan.

(f)
Successor LIBOR Rate.

(i)        If at any time the Bank determines (which determination shall be
conclusive absent manifest error) that (A) the circumstances set forth in clause
(e) have arisen and such circumstances are unlikely to be temporary, (B) the
applicable supervisor or administrator of the LIBOR Rate or a Governmental
Authority having jurisdiction over the Bank has made a public statement
identifying a specific date after which the LIBOR Rate shall no longer be made
available or used for determining interest rates for loans (such specific date,
the “LIBOR Scheduled Unavailability Date”), or (C) a rate other than the LIBOR
Rate has become a widely recognized benchmark interest rate for newly originated
loans of this type made in Dollars to borrowers domiciled in the United States,
then the Bank may, in consultation with the Company, select an alternate
benchmark interest rate (including any credit spread or other adjustments to
such alternate benchmark (if any) incorporated therein) to replace the LIBOR
Rate for purposes of this Credit Agreement (such rate, the “LIBOR Successor
Rate”).

(ii)        The Bank and the Company shall negotiate in good faith any
amendments to this Agreement as may be necessary and appropriate to effectively
replace the LIBOR Rate with the LIBOR Successor Rate and incorporate any LIBOR
Successor Rate Conforming Changes related thereto. Notwithstanding anything to
the contrary in Section 29, any such amendment entered into by the Bank and the
Company shall become effective without any further action or consent of any
other party to this Agreement.

(iii)        If the Bank determines (which determination shall be conclusive
absent manifest error) that the circumstances under Section 6(e)(i) have arisen
or the LIBOR Scheduled Unavailability Date has occurred, then (A) the Bank shall
promptly notify the Company of such determination, which notice may be given by
telephone, and (B) until such time as a LIBOR Successor Rate has been selected
and this Agreement has been amended to implement such LIBOR Successor Rate and
any LIBOR Successor Rate Conforming Changes, (1) the obligation of the Bank to
make or maintain LIBOR Rate Loans shall be suspended, (2) any borrowing request
that requests the continuation of any loan as, a LIBOR Rate Loan shall be
ineffective, (3) if any borrowing request requests a LIBOR Rate Loan, such loan
shall be made as an ABR Loan, and (4) the Alternate Base Rate shall be
determined without reference to the Adjusted LIBOR Rate component thereof.

--------------------------------------------------------------------------------

-13-

(iv)    The LIBOR Successor Rate and any LIBOR Successor Rate Conforming Changes
shall be determined, applied and implemented in a manner that gives due
consideration to the then-prevailing market practice in the United States for
determining, applying and implementing benchmark interest rates for newly
originated loans of this type made in Dollars to borrowers domiciled in the
United States. Notwithstanding anything contained herein to the contrary, for
purposes of this Agreement, no LIBOR Successor Rate selected in accordance with
the foregoing shall at any time be less than 0.00% per annum.

requested ABR Loan is to be made. Such notice shall specify (i) the effective
date and amount of each ABR Loan; and (ii) such other information in respect
thereof as reasonably requested by the Bank (each such notification a “Notice of
ABR Loan Borrowing”). Subject to the terms and conditions of this Agreement and
provided that the aggregate amount of all other previous Revolving Loans and the
requested ABR Loan does not exceed the Commitment Amount, the Bank shall make
each ABR Loan on the effective date specified therefor; provided, however, that
no ABR Loan shall be made unless at the time thereof no Event of Default shall
have occurred or be continuing.

Daily LIBOR Rate Loan, the Company shall notify the Bank in writing no later
than 10:00 a.m. (New York Time) on the date which is one (1) Business Day prior

requested Daily LIBOR Rate Loan does not exceed the Commitment Amount, the Bank
shall make each Daily LIBOR Rate Loan on the effective date specified therefor;
provided, however, that no Daily LIBOR Rate Loan shall be made unless at the
time thereof no Event of Default shall have occurred or be continuing.

(c)    LIBOR Rate Loan Request. Whenever the Company desires to obtain a LIBOR
Rate Loan, the Company shall notify the Bank in writing by delivering a
borrowing request to the Bank on or before 10:00 a.m. (New York time) on a

--------------------------------------------------------------------------------

-14-

8.Continuations and Conversion Elections.

(a)    Any LIBOR Rate Loan shall be automatically continued as a LIBOR Rate Loan
at the then applicable Adjusted LIBOR Rate and in an amount equal to the
principal amount of the expiring LIBOR Rate Loan less any applicable Principal
Repayment Amount made by the Company; provided, however, that no portion of the
outstanding principal amount of a LIBOR Rate Loan may be continued as a LIBOR
Rate Loan when any Event of Default has occurred and is continuing. If any Event
of Default has occurred and is continuing (if the Bank does not otherwise elect
to exercise any right to accelerate the Loans hereunder), the LIBOR Rate Loan
shall automatically be continued as an ABR Rate Loan on the first day of the
next LIBOR Interest Period.

(b)    By delivering a conversion notice to the Bank on or before 10:00 a.m.,
New York City time, on a Business Day, the Company may from time to time
irrevocably elect, on not less than two (2) nor more than five (5) Business
Days’ notice, that all or any portion of any LIBOR Rate Loan, in an aggregate
minimum amount of $50,000 and integral multiples of $10,000, be converted on the
last day of a LIBOR Interest Period into a LIBOR Rate Loan with a different
LIBOR Interest Period; provided, however, that no portion of the outstanding
principal amount of any LIBOR Rate Loan may be continued as a LIBOR Rate Loan
when any Event of Default has occurred and is continuing, and no portion of the
outstanding principal amount of any LIBOR Rate Loan may be converted to LIBOR
Rate Loan of a different duration if such LIBOR Rate Loan relates to any Hedging
Obligation.
 
9.Repayments, Prepayments and Interest

(a)    Repayment. The principal amount of the Revolving Loans shall be due and
payable on the earlier of DEMAND by the Bank or the Maturity Date.

(b)    Voluntary Prepayment. ABR Loans may be prepaid in whole or in part at any
time without premium or penalty. LIBOR Rate Loans may be prepaid upon the terms
and conditions set forth herein. For LIBOR Rate Loans in connection with which
the Company has or may incur Hedging Obligations, additional obligations may be
associated with prepayment, in accordance with the terms and conditions of the
applicable Hedging Contracts. The Company shall give the Bank, no later than
10:00 a.m., New York City time, at least four (4) Business Days notice of any
proposed prepayment of any LIBOR Rate Loans, specifying the proposed date of
payment of such LIBOR Rate Loans, and the principal amount to be paid. Each
partial prepayment of the principal amount of LIBOR Rate Loans shall be in an
integral multiple of $10,000 and accompanied by the payment of all charges
outstanding on such LIBOR Rate Loans (including the LIBOR Breakage Fee) and of
all accrued interest on the principal repaid to the date of payment.

--------------------------------------------------------------------------------

-15-

(c)    LIBOR Breakage Fee. Upon: (i) any default by the Company in making any
borrowing of, conversion into or continuation of any LIBOR Rate Loan following
the Company’s delivery of a borrowing request or continuation/conversion notice
hereunder or (ii) any prepayment of a LIBOR Rate Loan on any day that is not the
last day of the relevant LIBOR Interest Period (regardless of the source of such
prepayment and whether voluntary, by acceleration or otherwise), the Company
shall pay an amount (“LIBOR Breakage Fee”), as calculated by the Bank, equal to
the amount of any losses, expenses and liabilities (including without limitation
any loss of margin and anticipated profits) that the Bank may sustain as a
result of such default or payment. The Company understands, agrees and
acknowledges that: (i) the Bank does not have any obligation to purchase, sell
and/or match funds in connection with the use of the LIBOR Rate as a basis for
calculating the rate of interest on a LIBOR Rate Loan, (ii) the LIBOR Rate may
be used merely as a reference in determining such rate, and (iii) the Company
has accepted the LIBOR Rate as a reasonable and fair basis for calculating the
LIBOR Breakage Fee and other funding losses incurred by the Bank. The Company
further agrees to pay the LIBOR Breakage Fee and other funding losses, if any,
whether or not the Bank elects to purchase, sell and/or match funds.

(d)    LIBOR Rate Lending Unlawful. If the Bank shall determine (which
determination shall, upon notice thereof to the Company be conclusive and
binding on the Company) that the introduction of or any change in or in the
interpretation of any law, rule, regulation or guideline, (whether or not having
the force of law) makes it unlawful, or any central bank or other governmental
authority asserts that it is unlawful, for the Bank to make, continue or
maintain any LIBOR Rate Loan as a LIBOR Rate Loan of a certain duration, the
obligations of the Bank to make, continue or maintain any such LIBOR Rate Loans
shall, upon such determination, forthwith be suspended until the Bank shall
notify the Company that the circumstances causing such suspension no longer
exist, and all LIBOR Rate Loans of such type shall automatically convert into an
ABR Loan at the end of the then current LIBOR Interest Periods with respect
thereto or sooner, if required by such law or assertion.

(e)    Increased Costs. If, on or after the date hereof, a Change in Law: (a)
shall impose, modify or deem applicable any reserve, special deposit or similar
requirement (including, without limitation, any such requirement imposed by the
Board) against assets of, deposits with or for the account of, or credit
extended by, the Bank or shall impose on the Bank or on the London interbank
market any other condition affecting its LIBOR Rate Loans or its obligation to
make LIBOR Rate Loans; or (b) shall impose on the Bank any other condition
affecting its LIBOR Rate Loans or its obligation to make LIBOR Rate Loans, and
the result of any of the foregoing is to increase the cost to the Bank of making
or maintaining any LIBOR Rate Loan, or to reduce the amount of any sum received
or receivable by the Bank under this Letter Agreement with respect thereto, by
an amount deemed by the Bank to be material, then, within 15 days after demand
by the Bank, the Company shall pay to the Bank such additional amount or amounts
as will compensate the Bank for such increased cost or reduction.

(f)    Increased Capital Costs. If any Change in Law affects or would affect the
amount of capital required or expected to be maintained by the Bank, or Person
controlling the Bank, and the Bank determines (in its sole and absolute
discretion) that the rate of return on its or such controlling Person’s capital
as a consequence of its commitments or the loans made by the Bank is

--------------------------------------------------------------------------------

-16-

reduced to a level below that which the Bank or such controlling Person could
have achieved but for the occurrence of any such circumstance, then, in any such
case upon notice from time to time by the Bank to the Company, the Company shall
immediately pay directly to the Bank additional amounts sufficient to compensate
the Bank or such controlling Person for such reduction in rate of return. A
statement of the Bank as to any such additional amount or amounts (including
calculations thereof in reasonable detail) shall, in the absence of manifest
error, be conclusive and binding on the Company. In determining such amount, the
Bank may use any method of averaging and attribution that it (in its sole and
absolute discretion) shall deem applicable.

(g)    Taxes. All payments by the Company of principal of, and interest on,
LIBOR Rate Loans and all other amounts payable hereunder shall be made free and
clear of and without deduction for any present or future income, excise, stamp
or franchise taxes and other taxes, fees, duties, withholdings or other charges
of any nature whatsoever imposed by any taxing authority, but excluding
franchise taxes and taxes imposed on or measured by the Bank’s net income or
receipts (such non-excluded items being called “Taxes”). In the event that any
withholding or deduction from any payment to be made by the Company hereunder is
required in respect of any Taxes pursuant to any applicable law, rule or
regulation, then the Company will:

(a)
pay directly to the relevant authority the full amount required to be so
withheld or deducted;

(b)
promptly forward to the Bank an official receipt or other documentation
satisfactory to the Bank evidencing such payment to such authority; and

(c)
pay to the Bank such additional amount or amounts as is necessary to ensure that
the net amount actually received by the Bank will equal the full amount the Bank
would have received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Bank with respect to
any payment received by the Bank hereunder, the Bank may pay such Taxes and the
Company will promptly pay such additional amount (including any penalties,
interest or expenses) as is necessary in order that the net amount received by
the Bank after the payment of such Taxes (including any Taxes on such additional
amount) shall equal the amount the Bank would have received had not such Taxes
been asserted.

If the Company fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Bank the required receipts or other required
documentary evidence, the Company shall indemnify the Bank for any incremental
Taxes, interest or penalties that may become payable by the Bank as a result of
any such failure.
