For purposes hereof, “Prime Rate” shall mean the rate of interest per annum publicly announced from time to time by SunTrust as its prime rate in effect at its principal office in Atlanta, Georgia (the Prime Rate not being intended to be the lowest or best rate of interest charged by SunTrust in connection with extensions of credit to debtors).

(b)    “Eurodollar Base Rate”:  with respect to each day during each Interest Period pertaining to a Eurodollar Loan, the rate per annum equal to the London Interbank Offered Rate for a period equal to such Interest Period commencing on the first day of such Interest Period appearing on Reuters Screen LIBOR 01 Page (or any successor page) as of 11:00 A.M., London time, two Business Days prior to the beginning of such Interest Period.  In the event that such rate does not appear on Reuters Screen LIBOR 01 Page (or any successor page), the “Eurodollar Base Rate” shall be determined by reference to such other comparable publicly available service for displaying eurodollar rates as may be selected by the Administrative Agent or, in the absence of such availability, by reference to the rate at which the Administrative Agent is offered Dollar deposits at or about 11:00 A.M., Charlotte time, two Business Days prior to the beginning of such Interest Period in the interbank eurodollar market where its eurodollar and foreign currency and exchange operations are then being conducted for delivery on the first day of such Interest Period for the number of days comprised therein; and if the Eurodollar Base Rate shall be less than zero, such rate shall be deemed zero for purposes of this Agreement.


(c)    “FATCA” Sections 1471 through 1474 of the Code, as of the date of this Agreement (or any amended or successor version that is substantively comparable and not materially more onerous to comply with), any current or future regulations or official interpretations thereof and any agreement entered into pursuant to Section 1471(b)(1) of the Code.


(d)    “Federal Funds Effective Rate”:  for any day, the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System, as published on the next succeeding Business Day by the Federal Reserve Bank of New York, and if the Federal Funds Effective Rate shall be less than zero, such rate shall be deemed zero for purposes of this Agreement.











(e)    “LIBOR Market Index Rate”:  means, for any day, (a) the rate per annum equal to the London Interbank Offered Rate for an Interest Period of one month appearing on Reuters Screen LIBOR 01 Page (or any successor page) at approximately 11:00 a.m., London time for such day, provided, if such day is not a Business Day, the immediately preceding Business Day; or (b) if for any reason the rate specified in clause (a) of this definition does not so appear on Reuters Screen LIBOR 01 Page (or any successor page), the average of the interest rates per annum at which dollar deposits of $5,000,000 and for a one-month maturity are offered by the respective principal London offices of two reference banks reasonably designated by the Administrative Agent in immediately available funds in the London interbank market at approximately 11:00 a.m., London time, for such day; and if the LIBOR Market Index Rate shall be less than zero, such rate shall be deemed zero for purposes of this Agreement.

(b)    If any Lender shall have determined that any Change in Law regarding capital or liquidity requirements shall have the effect of reducing the rate of return on such Lender’s or such Lender’s holding company’s capital as a consequence of its obligations hereunder to a level below that which such Lender or such Lender’s holding company could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy and liquidity) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall, within 15 days of such request, pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for such reduction; provided that the Borrower shall not be required to compensate a Lender pursuant to this paragraph for any amounts incurred more than three months prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; and provided further that, if the circumstances giving rise to such claim have a retroactive effect, then such period for which the Borrower shall be required to compensate the Lenders shall be extended to include the period of such retroactive effect

	LIMITED CONSENT




A.
