to have the Subject Loan bear interest at the Eurodollar Rate subject to subsection 2.05 (“Eurodollar Restatement Notice”). Upon the commencement of each Interest Period, Borrower shall be deemed to have represented and warranted to Bank

shall bear interest at a rate per annum which shall at all times during any Interest Period applicable thereto be the relevant Eurodollar Rate for such Interest Period plus the Applicable Margin in effect from time to time. 








 (c) Default Interest — Notwithstanding the above provisions, if a Default Under This
Agreement or as Event of Default is in existence, all outstanding amounts of principal and, to the extent permitted by law, all overdue interest in respect of the Subject Loan shall bear interest, payable on demand, at a fluctuating rate per annum
equal to 2% per annum above the interest rate which is or would be applicable from time to time pursuant to subsection 2.04(a) to Prime Rate Loans in effect from time to time. 
  
 (d) Computations of Interest — All computations of interest hereunder shall be made in accordance with
subsection 8.10.

 (f) Accrual and Payment of Interest — Interest on the Subject
Loan shall accrue from and including the date of any borrowing and shall be payable on Maturity, on any repayment, prepayment or conversion (on the amount repaid, prepaid or converted) and, after Maturity, on demand, and in the case of any Subject
Loan, semi-annually on January 15 and July 15 of each year (or, if such day is not a Banking Day, the next succeeding Banking Day). 
  
 (g) Interest Margins — As used herein, the term “Applicable Margin” shall mean the particular rate per annum
determined by Bank in accordance with the Pricing Grid Table which appears below, based upon the results of the computation of the Leverage Ratio (as defined in Exhibit A) of Guarantor and such Pricing Grid Table, and the following
provisions: 
  
 (i) Commencing with the fiscal quarter of
Guarantor ended on or nearest to September 30, 2001, and continuing with each fiscal quarter thereafter, Bank will determine the Applicable Margin in accordance with the Pricing Grid Table for the Interest Period commencing January 15, 2002 and each
Interest Period thereafter, based on the consolidated Leverage Ratio of Guarantor for the most recently completed four (4) fiscal quarters, and identified in such Pricing Grid Table. Changes in the Applicable Margin based upon changes in such ratio
shall become effective on the first day of the month following the receipt by Bank pursuant to subsection 3A.01, as applicable, of the consolidated financial statements of Guarantor. 
  
 (ii) Notwithstanding the above provisions, during any period when (A) Guarantor has failed to timely deliver its financial
statements referred to in subsection 3A.01, (B) a Default Under This Agreement has occurred and is continuing, or (C) an Event of Default has occurred and is continuing, the Applicable Margin shall be the highest rate per annum indicated in the
Pricing Grid Table, regardless of Guarantor’s Leverage Ratio at such time. 







 (iii) Any changes in the Applicable Margin shall be determined by Bank in accordance with the above
provisions, and Bank will promptly provide notice of such determinations to ONMS. Any such determination by Bank pursuant to this subsection 2.04 shall be conclusive and binding absent manifest error.

 2.05 INCREASED COSTS,
ILLEGALITY, ETC. — (a) In the event that Bank shall have determined on a reasonable basis (which determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto): 
  
 (i) on any date for determining the Eurodollar Rate for any Interest Period
that, by reason of any changes arising after the date hereof affecting the applicable interbank Eurodollar market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of
Eurodollar Rate; 
  
 (ii) at any time, that Bank shall incur
increased costs or reductions in the amounts received or receivable hereunder in an amount which Bank reasonably deems material with respect to any Eurodollar Loan (other than any increased cost or reduction in the amount received or receivable
resulting from the imposition of or a change in the rate of taxes or similar charges) because of (x) any change since the date hereof in any applicable law, governmental rule, regulation, guideline, order or request (whether or not having the force
of law), or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline, order or request (such as, for example, but not limited to, a change in official reserve
requirements, but, in all events, excluding reserves includable in the Eurodollar Rate pursuant to the definition thereof) and/or (y) other circumstances adversely affecting the interbank Eurodollar market or the position of Bank in such market; or

  
 (iii) at any time, that the making or continuance of any
Eurodollar Loan has become unlawful by compliance by Bank in good faith with any change since the date hereof in any law, governmental rule, regulation, guideline or order, or the interpretation or application thereof, or would conflict with any
thereof not having the force of law but with which Bank customarily complies or has become impracticable as a result of a contingency occurring after the date hereof which materially adversely affects the interbank Eurodollar market; 







 then, and in any such event, Bank shall (x) on or promptly following such date or time and
(y) promptly after the date on which such event no longer exists give notice (by telephone confirmed in writing) to ONMS of such determination. Thereafter (x) in the case of clause (i) above, Eurodollar Loan shall no longer be available until such
time as Bank notifies ONMS that the circumstances giving rise to such notice by Bank no longer exist, and any existing Eurodollar Loan shall be automatically converted to a Prime Rate Loan, (y) in the case of clause (ii) above, Borrower shall
pay to Bank, upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as Bank shall determine) as shall be required to compensate Bank, for such increased
costs or reductions in amounts receivable hereunder (a written notice as to the additional amounts owed to Bank, showing the basis for the calculation thereof submitted to ONMS by Bank shall, absent manifest error, be final and conclusive and
binding upon all parties hereto) and (z) in the case of clause (iii) above, the Eurodollar Loan shall be converted to a Prime Rate Loan as promptly as possible and, in any event, within the time period required by law. 
  
 (b) If Bank shall have determined that after the date hereof, the adoption
of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation of administration thereof lay any governmental authority, central bank or comparable agency charged by law with the
interpretation or administration thereof, or compliance by Bank or its parent corporation with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank, or comparable agency, in
each case trade subsequent to the date hereof, has or would have the effect of reducing by an amount reasonably deemed by Bank to be material the rate of return on Bank’s or its patent corporation’s capital or assets as a consequence of
Bank’s commitments or obligations hereunder to a level below that which Bank or its parent corporation could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration Bank’s or its parent
corporation’s policies with respect to capital adequacy), then from time to time, within five days after demand by Bank, Borrower shall pay to Bank such additional amount or amounts as will compensate Bank or its parent corporation for such
reduction. Bank, upon determining in good faith that any additional amounts will be payable pursuant to this subsection 2.05(b), will give prompt written notice thereof to ONMS, which notice shall set forth, in reasonable detail, the basis of the
calculation of such additional amounts, although the failure to give any such notice shall not release or diminish each Borrower’s obligations to pay additional amounts pursuant to this subsection 2.05(b) upon the subsequent receipt of such
notice. 
  
 2.06 BREAKAGE COMPENSATION — Borrower shall
compensate Bank, upon its written request (which request shall set forth in reasonable detail the basis for requesting 








 
and the method of calculating such compensation), for all reasonable losses, expenses and liabilities (including, without limitation, any loss, expense or
liability incurred by reason of the liquidation or reemployment of deposits or other fiends required by Bank to fund its Eurodollar Loan) which Bank may sustain., (i) if for any reason (other than a default by Bank), borrowing of a Eurodollar Loan
does not occur on a date specified therefor in a Eurodollar Restatement Notice under subsection 2.03(d) or does not occur because of the existence Pf an Event of Default or Default Under The Agreement upon the commencement of an Interest Period,
(ii) if any repayment, prepayment, conversion or continuation of any of its Eurodollar Loan occurs on a date which is not the last day of an Interest Period applicable thereto; (iii) if any prepayment of any of its Eurodollar Loan is not made
on any date specified in a notice of prepayment given by a Borrower, or (iv) as a consequence of (x) any other default by a Borrower to repay its Eurodollar Loan when required by the terms of this Agreement or (y) 4n election trade pursuant to
subsection 2.05. Such loss, cost, expense and liability to Bank shall be deemed to include an amount determined by Bank to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such loan had such
event not occurred, at the interest rate that would have been applicable to such loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to effect a
conversion or continuation, for the period that would have been the Interest Period for such loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which Bank would bid were it to
bid, at the commencement of such period. A certificate of Bank setting forth any amount or amounts that Bank is entitled to receive pursuant to this section shall be delivered to ONMS and shall be conclusive absent manifest error. Borrower shall pay
Bank the amount shown as due on any such request within ten days after receipt thereof.
