Unless otherwise specified herein, all accounting terms used herein shall be interpreted, all accounting determinations hereunder shall be made, and all financial statements required to be delivered hereunder shall be prepared in accordance with generally accepted accounting principles in the United States as in effect from time to time, applied on a basis consistent (except for changes concurred in by the Borrower's independent public accountants) with the then most recent audited consolidated financial statements of the Borrower and its Consolidated Subsidiaries delivered to the Lenders; provided that, if the Borrower notifies the Administrative Agent that the Borrower wishes to amend any covenant in Article 5 to eliminate the effect of any change in generally accepted accounting principles on the operation of such covenant (or if the Administrative Agent notifies the Borrower that the Required Lenders wish to amend Article 5 for such purpose), then the Borrower's compliance with such covenant shall be determined on the basis of generally accepted accounting principles in effect immediately before the relevant change in generally accepted accounting principles became effective, until either such notice is withdrawn or such covenant is amended in a manner satisfactory to the Borrower and the Required Lenders.

SECTION 1.3. Types of Loans and Borrowings. The term "Borrowing" denotes the aggregation of Loans of one or more Lenders to be made to the Borrower pursuant to Article 2 on the same date, all of which Loans are of the same Type (subject to Article 8) and, except in the case of Base Rate Loans, have the same initial Interest Period. The "Type" of a Loan refers to the determination whether such Loan is a Euro-Dollar Loan, a Base Rate Loan or a Money Market Loan, each of which constitutes a "Type".

ARTICLE 2
THE CREDIT

SECTION 2.1. Commitments to Lend. During the Revolving Credit Period, each Lender severally agrees, on the terms and conditions set forth in this Agreement, to make Loans to the Borrower from time to time in an aggregate amount at any time outstanding not to exceed the amount of its Commitment. Within the limits specified in this Agreement, the Borrower may borrow under this Section 2.1, prepay Loans to the extent permitted by Section 2.11 and reborrow at any time during the Revolving Credit Period pursuant to this Section 2.1. Each Borrowing under this Section 2.1 shall be in the aggregate principal amount of $25,000,000 or any larger multiple of $1,000,000 (except that any such Borrowing may be in the aggregate amount of the unused Commitments) and shall be made from the several Lenders ratably in proportion to their respective Commitments.

SECTION 2.2. Notice of Committed Borrowings. The Borrower shall give the Administrative Agent notice (a "Notice of Committed Borrowing") not later than 10:30 A.M. (New York City time) on (x) the date of each Base Rate Borrowing and (y) the third Euro-Dollar Business Day before each Euro-Dollar Borrowing, specifying:

(a) the date of such Borrowing, which shall be a Domestic Business Day in the case of a Base Rate Borrowing or a Euro-Dollar Business Day in the case of a Euro-Dollar Borrowing,

(b) the aggregate amount of such Borrowing,

(d) in the case of a Euro-Dollar Borrowing, the duration of the initial Interest Period applicable thereto, subject to the provisions of the definition of Interest Period.

SECTION 2.3. Money Market Borrowings.

(a) The Money Market Option. In addition to Committed Borrowings pursuant to Section 2.1, but within the limitations of the Commitments as contemplated by Section 3.2(b), the Borrower may, as set forth in this Section, request (but is not obligated to request) the Lenders from time to time prior to the Termination Date to make offers to make Money Market Loans to the Borrower. The Lenders may make, but shall have no obligation to make, such offers and the Borrower may accept, but shall have no obligation to accept, any such offers in the manner set forth in this Section.

(b) Money Market Quote Request. When the Borrower wishes to request offers to make Money Market Loans under this Section, it shall transmit to the Administrative Agent by facsimile transmission or electronic transmission (PDF) a Money Market Quote Request substantially in the form of Exhibit E hereto (a "Money Market Quote Request") so as to be received no later than 10:30 A.M. (New York City time) on (x) the fifth Euro-Dollar Business Day prior to the date of Borrowing proposed therein, in the case of a LIBOR Auction or (y) the Domestic Business Day next preceding the date of Borrowing proposed therein, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Administrative Agent shall have mutually agreed and shall have notified to the Lenders not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective) specifying:

(i) the proposed date of Borrowing, which shall be a Euro-Dollar Business Day in the case of a LIBOR Auction or a Domestic Business Day in the case of an Absolute Rate Auction,

(ii) the proposed aggregate amount of such Borrowing, which shall be $25,000,000 or a larger multiple of $1,000,000,

(iii) the duration of the Interest Period applicable thereto, subject to the provisions of the definition of Interest Period, and

(iv) whether the Money Market Quotes requested are to set forth a Money Market Margin or a Money Market Absolute Rate. The Borrower may request (but is not obligated to request) offers to make Money Market Loans for more than one Interest Period in a single Money Market Quote Request. No Money Market Quote Request shall be given within five Euro-Dollar Business Days (or such other number of days as the Borrower and the Administrative Agent may agree) of any other Money Market Quote Request.

(c) Invitation for Money Market Quotes. Promptly upon receipt of a Money Market Quote Request, the Administrative Agent shall send to the Lenders by facsimile transmission an Invitation for Money Market Quotes substantially in the form of Exhibit F hereto (an "Invitation for Money Market Quotes"), which shall constitute an invitation by the Borrower to each Lender to submit Money Market Quotes offering to make the Money Market Loans to which such Money Market Quote Request relates in accordance with this Section.

(d) Submission and Contents of Money Market Quotes. (i) Each Lender may submit a Money Market Quote containing an offer or offers to make Money Market Loans in response to any Invitation for Money Market Quotes. Each Money Market Quote must comply with the requirements of this subsection (d) and must be submitted to the Administrative Agent by facsimile transmission at its offices specified in or pursuant to Section 9.1 not later than (x) 2:00 P.M. (New York City time) on the fourth Euro-Dollar Business Day prior to the proposed date of Borrowing, in the case of a LIBOR Auction or (y) 9:30 A.M. (New York City time) on the proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Administrative Agent shall have mutually agreed and shall have notified to the Lenders not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective); provided that Money Market Quotes submitted by the Administrative Agent (or any Affiliate of the Administrative Agent) in the capacity of a Lender may be submitted, and may only be submitted, if the Administrative Agent or such Affiliate notifies the Borrower of the terms of the offer or offers contained therein not later than (x) one hour prior to the deadline for the other Lenders, in the case of a LIBOR Auction or (y) 15 minutes prior to the deadline for the other Lenders, in the case of an Absolute Rate Auction. Subject to Articles 3 and 6, any Money Market Quote so made shall be irrevocable except with the written consent of the Administrative Agent given on the instructions of the Borrower.

(ii) Each Money Market Quote shall be in substantially the form of Exhibit G hereto and shall in any case specify:

(A) the proposed date of Borrowing,

(B) the principal amount of the Money Market Loan for which each such offer is being made, which principal amount (w) may be greater than or less than the Commitment of the quoting Lender, (x) must be $5,000,000 or a larger multiple of $1,000,000, (y) may not exceed the principal amount of Money Market Loans for which offers were requested and (z) may be subject to an aggregate limitation as to the principal amount of Money Market Loans for which offers being made by such quoting Lender may be accepted,

(C) in the case of a LIBOR Auction, the margin above or below the applicable London Interbank Offered Rate (the "Money Market Margin") offered for each such Money Market Loan, expressed as a percentage (specified to the nearest 1/10,000th of 1%) to be added to or subtracted from such base rate,

(D) in the case of an Absolute Rate Auction, the rate of interest per annum (specified to the nearest 1/10,000th of 1%) (the "Money Market Absolute Rate") offered for each such Money Market Loan, and

(E) the identity of the quoting Lender.

A Money Market Quote may set forth up to five separate offers by the quoting Lender with respect to each Interest Period specified in the related Invitation for Money Market Quotes.

(iii) Any Money Market Quote shall be disregarded if it:

(A) is not substantially in conformity with Exhibit G hereto or does not specify all of the information required by subsection (d)(ii);

(B) contains qualifying, conditional or similar language;

> (C) proposes terms other than or in addition to those set forth in the applicable Invitation for Money Market Quotes; or

(D) arrives after the time set forth in subsection (d)(i).

(e) Notice to Borrower. The Administrative Agent shall promptly notify the Borrower of the terms (x) of any Money Market Quote submitted by a Lender that is in accordance with subsection (d) and (y) of any Money Market Quote that amends, modifies or is otherwise inconsistent with a previous Money Market Quote submitted by such Lender with respect to the same Money Market Quote Request. Any such subsequent Money Market Quote shall be disregarded by the Administrative Agent unless such subsequent Money Market Quote is submitted solely to correct a manifest error in such former Money Market Quote. The Administrative Agent's notice to the Borrower shall specify (A) the aggregate principal amount of Money Market Loans for which offers have been received for each Interest Period specified in the related Money Market Quote Request, (B) the respective principal amounts and Money Market Margins or Money Market Absolute Rates, as the case may be, so offered and (C) if applicable, limitations on the aggregate principal amount of Money Market Loans for which offers in any single Money Market Quote may be accepted.

(f) Acceptance and Notice by Borrower. Not later than 10:30 A.M. (New York City time) on (x) the third Euro-Dollar Business Day prior to the proposed date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Administrative Agent shall have mutually agreed and shall have notified to the Lenders not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective), the Borrower shall notify the Administrative Agent of its acceptance or non-acceptance of the offers so notified to it pursuant to subsection (e). In the case of acceptance, such notice (a "Notice of Money Market Borrowing") shall specify the aggregate principal amount of offers for each Interest Period that are accepted. The Borrower may accept any Money Market Quote in whole or in part; provided that:

(i) the aggregate principal amount of each Money Market Borrowing may not exceed the applicable amount set forth in the related Money Market Quote Request,

(ii) the aggregate principal amount of each Money Market Borrowing must be $25,000,000 or a larger multiple of $1,000,000,

(iii) acceptance of offers may only be made on the basis of ascending Money Market Margins or Money Market Absolute Rates, as the case may be, and

(iv) the Borrower may not accept any offer that is described in subsection (d)(iii) or that otherwise fails to comply with the requirements of this Agreement.

(g) Allocation by Administrative Agent. If offers are made by two or more Lenders with the same Money Market Margins or Money Market Absolute Rates, as the case may be, for a greater aggregate principal amount than the amount in respect of which such offers are accepted for the related Interest Period, the principal amount of Money Market Loans in respect of which such offers are accepted shall be allocated by the Administrative Agent among such Lenders as nearly as possible (in such multiples, not greater than $1,000,000, as the Administrative Agent may deem appropriate) in proportion to the aggregate principal amounts of such offers. Determinations by the Administrative Agent of the amounts of Money Market Loans shall be conclusive in the absence of manifest error.

SECTION 2.4. Notice to Lenders; Funding of Loans.>

(a) Upon receipt of a Notice of Borrowing, the Administrative Agent shall promptly notify each Lender participating therein of the contents thereof and of such Lender's share (if any) of such Borrowing and such Notice of Borrowing shall not thereafter be revocable by the Borrower.

(b) Not later than 12:00 Noon (New York City time) on the date of each Borrowing, each Lender participating therein shall make available its share of such Borrowing, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address specified in or pursuant to Section 9.1. Unless the Administrative Agent determines that any applicable condition specified in Article 3 has not been satisfied, the Administrative Agent will make the funds so received from the Lenders available to the Borrower at the Administrative Agent's aforesaid address.

(c) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available to the Administrative Agent on the date of such Borrowing in accordance with subsection (b) of this Section 2.4 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such share available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable thereto pursuant to Section 2.6 and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender's Loan included in such Borrowing for purposes of this Agreement.

SECTION 2.5. Maturity of Loans. (a) Each Committed Loan shall mature, and the principal amount thereof shall be payable in full together with accrued interest thereon, on the Termination Date.

(b) Each Money Market Loan included in any Money Market Borrowing shall mature, and the principal amount thereof shall be payable in full together with accrued interest thereon, on the last day of the Interest Period applicable to such Borrowing.

SECTION 2.6. Interest Rates. (a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the day such Loan is made to but excluding the day it becomes due, at a rate per annum equal to the Base Rate for such day. Such interest shall be payable at maturity, quarterly in arrears on each Quarterly Date prior to maturity and, with respect to the principal amount of any Base Rate Loan converted to a Fixed Rate Loan, on the date such Loan is so converted. Any overdue principal of or interest on any Base Rate Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 2% plus the Base Rate for such day.

(b) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for each day during each Interest Period applicable thereto, at a rate per annum equal to the sum of the Applicable Margin for such day plus the London Interbank Offered Rate applicable to such Interest Period. Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than three months, at intervals of three months after the first day thereof. The "London Interbank Offered Rate" applicable to any Interest Period means the rate per annum determined on the basis of the rate for deposits in U.S. dollars for a period equal to such Interest Period commencing on the first day of such Interest Period appearing on LIBOR1 of the Reuters screen as of 11:00 A.M. (London time) two Euro-Dollar Business Days prior to the beginning of such Interest Period. In the event that such rate does not appear on LIBOR1 of the Reuters screen (or otherwise on such screen), the London Interbank Offered Rate shall be determined by reference to such other comparable publicly available service for displaying eurodollar rates as may be selected by the Euro-Dollar Reference Lenders or, in the absence of such availability, by reference to the average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective rates per annum at which deposits in U.S. dollars are offered to each of the Euro-Dollar Reference Lenders in the London interbank market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the first day of such Interest Period in an amount approximately equal to the principal amount of the Euro-Dollar Loan of such Euro-Dollar Reference Lender to which such Interest Period is to apply and for a period of time comparable to such Interest Period.

(c) Any overdue principal of or interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the higher of (i) the sum of 2% plus the Applicable Margin for such day plus the London Interbank Offered Rate applicable to such Loan on the day before such payment was due and (ii) the sum of 2% plus the Applicable Margin for such day plus a rate per annum equal to the average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective rates per annum at which one day (or, if such amount due remains unpaid more than three Euro-Dollar Business Days, then for such other period of time not longer than three months as the Administrative Agent may select) deposits in dollars in an amount approximately equal to such overdue payment due to each of the Euro-Dollar Reference Lenders are offered to such Euro-Dollar Reference Lender in the London interbank market for the applicable period (or, if the circumstances described in clause (a) or (b) of Section 8.1 shall exist, at a rate per annum equal to the sum of 2% plus the Base Rate for such day).

(d) Subject to Section 8.1, each Money Market LIBOR Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the sum of the London Interbank Offered Rate for such Interest Period (determined in accordance with Section 2.6(b) as if the related Money Market LIBOR Borrowing were a Euro-Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the Lender making such Loan in accordance with Section 2.3. Each Money Market Absolute Rate Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the Money Market Absolute Rate quoted by the Lender making such Loan in accordance with Section 2.3. Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than three months, at intervals of three months after the first day thereof. Any overdue principal of or interest on any Money Market Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 2% plus the Base Rate for such day.

e) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder. The Administrative Agent shall give prompt notice to the Borrower and the participating Lenders of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error.

(f) Each Euro-Dollar Reference Lender agrees to use its best efforts to furnish quotations to the Administrative Agent as contemplated by this Section. If any Euro-Dollar Reference Lender does not furnish a timely quotation, the Administrative Agent shall determine the relevant interest rate on the basis of the quotation or quotations furnished by the remaining Euro-Dollar Reference Lender or Lenders or, if none of such quotations is available on a timely basis, the provisions of Section 8.1 shall apply.

SECTION 2.7. Regulation D Compensation. Each Lender may require the Borrower to pay, contemporaneously with each payment of interest on the Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such Lender at a rate per annum determined by such Lender up to but not exceeding the excess of (i) (A) the applicable London Interbank Offered Rate divided by (B) one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank Offered Rate. Any Lender wishing to require payment of such additional interest (x) shall so notify the Borrower and the Administrative Agent, in which case such additional interest on the Euro-Dollar Loans of such Lender shall be payable to such Lender at the place indicated in such notice with respect to each Interest Period commencing at least three Euro-Dollar Business Days after the giving of such notice and (y) shall notify the Borrower at least five Euro-Dollar Business Days prior to each date on which interest is payable on the Euro-Dollar Loans of the amount then due it under this Section.

"Euro-Dollar Reserve Percentage" means for any day that percentage (expressed as a decimal) which is in effect on such day, as prescribed by the Board of Governors of the Federal Reserve System (or any successor) for determining the maximum reserve requirement for a member bank of the Federal Reserve System in New York City with deposits exceeding five billion dollars in respect of "Eurocurrency liabilities" (or in respect of any other category of liabilities which includes deposits by reference to which the interest rate on Euro-Dollar Loans is determined or any category of extensions of credit or other assets which includes loans by a non-United States office of any Lender to United States residents). The compensation payable pursuant to this Section shall be adjusted automatically on and as of the effective date of any change in the Euro-Dollar Reserve Percentage.

SECTION 2.8. Facility Fees. The Borrower shall pay to the Administrative Agent a facility fee calculated for each day at the Facility Fee Rate for such day (determined in accordance with the Pricing Grid). Such facility fee shall accrue for each day (i) from and including the Effective Date to but excluding the date on which the Commitments terminate in their entirety, on the aggregate amount of the Commitments (whether used or unused) then in effect and (ii) from and including such date of termination to but excluding the date on which no Loans are outstanding, on the aggregate outstanding principal amount of the Loans on such day. Such facility fee shall be allocated among the Lenders ratably in proportion to their Commitments; provided that any facility fee accruing after the Commitments terminate in their entirety shall be allocated among the Lenders ratably in proportion to the unpaid principal amounts of their respective Loans. Accrued fees under this Section shall be payable quarterly in arrears on each Quarterly Date and on the Termination Date; provided that fees accruing after the Termination Date shall be payable on demand.

font size="3"> SECTION 2.9. Optional Termination, Reduction or Extension of Commitments. (a) The Borrower may, upon at least three Domestic Business Days' notice to the Administrative Agent, (i) terminate the Commitments at any time, if no Loans are outstanding at such time (after giving effect to any optional prepayments to be made at such time) or (ii) ratably reduce from time to time by an aggregate amount of $25,000,000 or a larger multiple of $1,000,000, the aggregate amount of the Commitments in excess of the aggregate outstanding amount of the Loans.

(b) On each of the first and second anniversary of the Closing Date (each, an "Extension Date"), the Borrower shall have the right, with the consent of the Required Lenders and subject to the terms and conditions of this Section 2.9(b), to extend the Termination Date then in effect (each, an "Extension Effective Date") by one additional year (which date shall become the Termination Date for the consenting Lender(s)); provided, that (i) the representations and warranties of the Borrower set forth in this Agreement shall be true and correct in all material respects on such Extension Date both before and immediately after giving effect to the proposed Termination Date extension, (ii) no Default shall have occurred and be continuing on such Extension Date both before and immediately after giving effect to the proposed Termination Date extension, (iii) on or prior to the Extension Effective Date, the Administrative Agent shall have received payment of all fees and interest accrued and payable on the applicable Extension Effective Date and (iv) the Termination Date shall not be extended with respect to any Lender without the consent of such Lender. At least 30 days prior to the relevant Extension Date, the Borrower shall provide written notice to the Administrative Agent of the proposed Termination Date extension. Upon receipt of any such notice, the Administrative Agent shall promptly notify each Lender thereof. Any Lender that shall not have provided its written consent to the proposed Termination Date extension by the date that is 10 Business Days prior to the relevant Extension Date shall be deemed to have elected not to approve of such extension. In the event any Lender does not (or is deemed to not) consent to an extension of the Termination Date then in effect with respect to such Lender (with respect to such extension, a "Non-Approving Lender"), such Lender's Commitment shall expire on the Termination Date then in effect with respect to such Lender and for all purposes of this Agreement "Termination Date" in respect of such Lender, the Loans made by it and any other amounts owing to such Lender hereunder shall mean such Termination Date. As of a given Extension Effective Date, the Commitments of the Lenders shall be deemed modified as appropriate to reflect the expiration of the Commitment of any Non-Approving Lender with respect to such extension. The Borrower shall have the right, at its sole expense, upon notice to the Administrative Agent and any Non-Approving Lender in respect of any Termination Date extension, to require such Lender to assign and delegate, prior to the relevant Extension Effective Date, without recourse (in accordance with and subject to the restrictions contained in Section 9.6) all its interests, rights and obligations under this Agreement and the other Loan Documents to which it is a party (other than any Money Market Loans held by it) to an assignee that shall assume such obligations (which assignee may be another Lender that accepts such assignment), provided, such assignee concurrently with such assignment approves such extension; and provided, further, that (i) the Borrower (unless the assignee is a Lender) shall have received the prior written consent of the Administrative Agent (which consent shall not unreasonably be withheld) and (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans (other than Money Market Loans), accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts).

SECTION 2.10. Method of Electing Interest Rates. (a) The Committed Loans included in each Borrowing shall bear interest initially at the type of rate specified by the Borrower in the applicable Notice of Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Group of Loans (subject in each case to the provisions of Article 8 and the last sentence of this subsection (a)), as follows:

(i) if such Loans are Base Rate Loans, the Borrower may elect to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day; and

(ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to convert such Loans to Base Rate Loans or elect to continue such Loans as Euro-Dollar Loans for an additional Interest Period, in either case effective on the last day of the then current Interest Period applicable to such Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest Rate Election") to the Administrative Agent not later than 10:30 A.M. (New York City time) on the third Euro-Dollar Business Day before the conversion or continuation selected in such notice is to be effective. A Notice of Interest Rate Election may, if it so specifies, apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group and (ii) the portion to which such Notice applies, and the remaining portion to which it does not apply, are each $25,000,000 or any larger multiple of $1,000,000. If no such notice is timely received prior to the end of an Interest Period, the Borrower shall be deemed to have elected that all Loans having such Interest Period be converted to Base Rate Loans. Notwithstanding the foregoing, the Borrower may not elect to convert any Loan to, or continue any Loan as, a Fixed Rate Loan pursuant to any Notice of Interest Rate Election if at the time such notice is delivered a Default shall have occurred and be continuing.

(b) Each Notice of Interest Rate Election shall specify:

(i) the Group of Loans (or portion thereof) to which such notice applies;

(ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of subsection (a) above;

(iii) if the Loans comprising such Group are to be converted, the new Type of Loans and, if the Loans being converted are to be Fixed Rate Loans, the duration of the next succeeding Interest Period applicable thereto; and

(iv) if such Loans are to be continued as Fixed Rate Loans for an additional Interest Period, the duration of such additional Interest Period. Each Interest Period specified in a Notice of Interest Rate Election shall comply with the provisions of the definition of Interest Period.

(c) Upon receipt of a Notice of Interest Rate Election from the Borrower pursuant to subsection (a) above, the Administrative Agent shall promptly notify each Lender of the contents thereof and such notice shall not thereafter be revocable by the Borrower.

(d) An election by the Borrower to change or continue the rate of interest applicable to any Group of Loans pursuant to this Section shall not constitute a Borrowing subject to the provisions of Section 3.2.

SECTION 2.11. Optional Prepayments. (a) The Borrower may, (i) upon at least one Domestic Business Day's notice to the Administrative Agent, prepay the Group of Base Rate Loans (or any Money Market Borrowing bearing interest at the Base Rate pursuant to Section 8.1) or (ii) upon at least, in the case of Euro-Dollar Loans, three Euro-Dollar Business Days' notice to the Administrative Agent, and subject to Section 2.14, prepay any Group of Euro-Dollar Loans, in each case in whole at any time, or from time to time in part in amounts aggregating $25,000,000 or any larger multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to the date of prepayment. Each such optional prepayment of a Group of Loans shall be applied to prepay ratably the Loans of the Lenders included in such Group.

(b) Except as provided in subsection (a) of this Section 2.11, the Borrower may not prepay all or any portion of the principal amount of any Money Market Loan prior to the maturity thereof without the consent of the Lender holding such Loan.

(c) Upon receipt of a notice of prepayment pursuant to this Section, the Administrative Agent shall promptly notify each Lender of the contents thereof and of such Lender's ratable share (if any) of such prepayment and such notice shall not thereafter be revocable by the Borrower.

SECTION 2.12. Scheduled Termination of Commitments. The Commitments shall terminate on the Termination Date.

SECTION 2.13. General Provisions as to Payments. (a) The Borrower shall make each payment of principal of, and interest on, the Loans and of fees hereunder, without setoff or counterclaim and not later than 12:00 Noon (New York City time) on the date when due, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address referred to in Section 9.1. The Administrative Agent will promptly distribute to each Lender, for the account of its Applicable Lending Office, its ratable share of each such payment received by the Administrative Agent for the account of the Lenders. Whenever any payment of principal of, or interest on, the Base Rate Loans or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. Whenever any payment of principal of, or interest on, the Money Market Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day, unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time.

(b) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

SECTION 2.14. Funding Losses. If the Borrower makes any payment of principal with respect to any Fixed Rate Loan or any Fixed Rate Loan is converted (pursuant to Article 6 or 8 or otherwise) on any day other than the last day of the Interest Period applicable thereto, or if the Borrower fails to borrow, prepay, convert or continue any Fixed Rate Loans after notice has been given to any Lender in accordance with Section 2.4(a), 2.10(c) or 2.11(c), the Borrower shall reimburse each Lender within 15 days after demand for any resulting loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin for the period after any such payment or failure to borrow, provided that such Lender shall have delivered to the Borrower a certificate as to the amount of such loss or expense indicating in reasonable detail the computation thereof, which certificate shall be conclusive in the absence of manifest error.

SECTION 2.15. Computation of Interest and Fees. Interest based on the Prime Rate hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first day but excluding the last day). All other interest and fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day).

SECTION 2.16. Registry.

(a) The Administrative Agent shall maintain a register (the "Register") on which it will record the Commitment of each Lender, each Loan made by such Lender and each repayment of any Loan made by such Lender. Any such recordation by the Administrative Agent on the Register shall be conclusive, absent manifest error. With respect to any Lender, the assignment or other transfer of the Commitment of such Lender and the rights to the principal of, and interest on, any Loan made and Note issued pursuant to this Agreement shall not be effective until such assignment or other transfer is recorded on the Register and otherwise complies with Section 9.6(c). The registration of assignment or other transfer of all or part of the Commitment, Loans and Notes for a Lender shall be recorded by the Administrative Agent on the Register only upon the acceptance by the Administrative Agent of a properly executed and delivered Assignment and Assumption Agreement referred to in Section 9.6(c). The Register shall be available at the offices where kept by the Administrative Agent for inspection by the Borrower and any Lender at any reasonable time upon reasonable prior notice to the Administrative Agent. The Borrower may not replace any Lender pursuant to Section 8.6 unless, with respect to any Notes held by such Lender, the requirements of this subsection have been satisfied. Each Lender shall record on its internal records (including computerized systems) the foregoing information as to its own Commitment and Loans. Failure to make any such recordation, or any error in such recordation, shall not affect the obligations of the Borrower or any Lender under the Loan Documents.

(b) The Borrower hereby agrees that, upon the request of any Lender at any time, such Lender's Loans shall be evidenced by a promissory note or notes of the Borrower (each a "Note"), substantially in the form of Exhibit A hereto, payable to the order of such Lender and representing the obligation of the Borrower to pay the unpaid principal amount of the Loans made by such Lender, with interest as provided herein on the unpaid principal amount from time to time outstanding.

SECTION 2.17. Increase in Loans. The Borrower may, at any time by notice to the Administrative Agent, propose an increase in the total Commitments hereunder (each such proposed increase being a "Commitment Increase") either by having a Lender increase its Commitment then in effect (each an "Increasing Lender") (provided that, for the avoidance of doubt, any Lender may elect or decline, in its sole discretion, to be an Increasing Lender) or by adding as a Lender with a new Commitment hereunder a Person which is not then a Lender (each an "Assuming Lender") in each case with the approval of the Administrative Agent, which notice shall specify the name of each Increasing Lender and/or Assuming Lender, as applicable, the amount of the Commitment Increase and the portion thereof being assumed by each such Increasing Lender or Assuming Lender, and the date on which such Commitment Increase is to be effective (the "Commitment Increase Date") (which shall be a Domestic Business Day at least three Domestic Business Days after delivery of such notice and 30 days prior to the Termination Date); provided that:

(i) the minimum amount of the increase of the Commitment of any Increasing Lender, and the minimum amount of the Commitment of any Assuming Lender, as part of any Commitment Increase shall be $25,000,000 or a larger multiple of $5,000,000;

(ii) immediately after giving effect to any Commitment Increase, the total Commitments hereunder shall not exceed $1,250,000,000;

(iii) no Default shall have occurred and be continuing on the relevant Commitment Increase Date or shall result from any Commitment Increase; and

(iv) the representations and warranties of the Borrower contained in this Agreement shall be true in all material respects on and as of the date of the relevant Commitment Increase Date.

Each Commitment Increase (and the increase of the Commitment of each Increasing Lender and/or the new Commitment of each Assuming Lender, as applicable, resulting therefrom) shall become effective as of the relevant Commitment Increase Date upon receipt by the Administrative Agent, on or prior to 11:00 a.m., New York City time, on such Commitment Increase Date, of (A) a certificate of a duly authorized officer of the Borrower stating that the conditions with respect to such Commitment Increase under this Section 2.17 have been satisfied and (B) an agreement, in form and substance reasonably satisfactory to the Borrower and the Administrative Agent, pursuant to which, effective as of such Commitment Increase Date, the Commitment of each such Increasing Lender shall be increased and/or each such Assuming Lender shall undertake a Commitment, duly executed by such Increasing Lender or Assuming Lender, as the case may be, and the Borrower and acknowledged by the Administrative Agent. Upon the Administrative Agent's receipt of a fully executed agreement from each Increasing Lender and/or Assuming Lender referred to in clause (B) above, together with the certificate referred to in clause (A) above, the Administrative Agent shall record the information contained in each such agreement in the Register and give prompt notice of the relevant Commitment Increase to the Borrower and the Lenders (including, if applicable, each Assuming Lender). On each Commitment Increase Date, in the event Committed Loans are then outstanding, (i) each relevant Increasing Lender and Assuming Lender shall make available to the Administrative Agent such amounts in immediately available funds as the Administrative Agent shall determine, for the benefit of the other relevant Lenders, as being required in order to cause, after giving effect to such increase and the application of such amounts to make payments to such other relevant Lenders, the Committed Loans to be held ratably by all Lenders in accordance with their respective Commitments, (ii) the Borrower shall be deemed to have prepaid and reborrowed all outstanding Committed Loans as of such Commitment Increase Date (with such borrowing to consist of the Type of Loans, with related Interest Periods if applicable, specified in a notice delivered by the Borrower in accordance with the requirements of Section 2.2) and (iii) the Borrower shall pay to the Lenders the amounts, if any, payable under Section 2.14 as a result of such prepayment.

SECTION 4.6. Compliance with Laws. (a) The Borrower and its Consolidated Subsidiaries are in compliance in all material respects with all applicable provisions of the United States Interstate Commerce Commission Termination Act of 1995, as amended, and all regulations, orders, rulings and interpretations thereunder, except where the failure to so comply could not reasonably be expected to result in a Material Adverse Change.

(l) Liens upon real and/or personal property, which property was acquired after the Closing Date (by purchase, construction or otherwise) by the Borrower or any of its Subsidiaries, provided that each of such Liens exists only on such property; and

(a) The Borrower will not (i) consolidate or merge with or into any other Person or (ii) sell, lease or otherwise transfer, directly or indirectly, all or substantially all of its assets to any other Person; provided that the Borrower may merge or consolidate with another Person or sell all or substantially all of its assets to another Person if:

(A) the Person surviving such merger or consolidation, or the Person that acquires substantially all of the Borrower's assets, is a business corporation incorporated under the laws of a State of the United States of America;

(B) the Person surviving such merger or consolidation, if not the Borrower, or the Person that acquires substantially all of the Borrower's assets, (i) executes and delivers to the Administrative Agent and each of the Lenders an instrument in form reasonably satisfactory to the Administrative Agent pursuant to which such Person assumes all of the Borrower's obligations under the Loan Documents as theretofore amended or modified, including the full and punctual payment (whether at stated maturity, upon acceleration or otherwise) of the principal of and interest on each Loan made to the Borrower pursuant to this Agreement, the full and punctual payment of all other amounts payable hereunder and the performance of all of the other covenants and agreements contained herein and (ii) if requested by the Required Lenders, delivers an opinion of counsel reasonably satisfactory to the Required Lenders covering the matters set forth in Exhibits B-1 and B-2, in each case after giving effect to such merger, consolidation or sale of assets, as the case may be; and

(C) immediately after giving effect to such merger, consolidation or sale of assets, no Default shall have occurred and be continuing and the representations and warranties of the Borrower contained in this Agreement shall be true in all material respects as if made immediately after such merger, consolidation or sale of assets.

No Person who was the Borrower shall be released from any of its obligations hereunder upon the assumption of such obligations by another Person. For purposes of this Section, the term "consolidate with" means a transaction in which the Borrower and another corporation consolidate to form a new corporation pursuant to the laws of their jurisdictions of incorporation and in which the Borrower and such other corporation cease to exist as separate corporate entities.

(b) Subject to subsection (a) above and subsection (c) below, the Borrower and its Subsidiaries will not sell, lease or otherwise transfer, directly or indirectly, all or any substantial part of the assets of the Borrower and its Subsidiaries, taken as a whole, to any other Person.

(c) The Borrower will at all times own, directly or indirectly all of the shares of capital stock or other ownership interests of Norfolk Southern Railway Company, or the successor thereto by merger, consolidation or share exchange or the Person, if any, who has acquired substantially all of such corporation's assets ("NSRC"), except directors' qualifying shares. The Borrower will cause NSRC to continue to own and operate the railroads and related assets owned and operated by it on the date hereof; provided that nothing in this Section shall prohibit dispositions (by sale, merger or otherwise) by NSRC of (A) assets in the ordinary course of business or (B) obsolete or unproductive assets.

SECTION 5.10. Use of Proceeds. The proceeds of the Loans will be used by the Borrower for general corporate purposes of the Borrower and its Subsidiaries.

SECTION 5.11. Limitation on Subsidiary Debt . The Borrower will not permit any of its Subsidiaries to incur or at any time be liable with respect to any Debt except:

(i) Debt owing to the Borrower or a Subsidiary all of the outstanding common stock of which (other than directors' qualifying shares) is owned directly or indirectly by the Borrower;

(ii) Debt of Subsidiaries not otherwise permitted by this Section in an aggregate principal amount at any time outstanding not exceeding $500,000,000;

(vii) Debt of Subsidiaries incurred or assumed (in connection with an equipment trust agreement, conditional sale agreement, chattel mortgage or lease or otherwise) for the purpose of directly or indirectly financing all or any part of the cost of acquiring, constructing or rebuilding any asset and any renewal, extension or refinancing thereof; provided that the aggregate principal amount of such Debt (other than extensions, renewals and refinancings) incurred or assumed in any fiscal year of the Borrower pursuant to this clause (vii) shall not exceed $500,000,000.

SECTION 5.12. Transactions with Affiliates. The Borrower will not, and will not permit any Subsidiary to, directly or indirectly, pay any funds to or for the account of, make any Investment in, lease, sell, transfer or otherwise dispose of any assets, tangible or intangible, to, or participate in, or effect, any transaction with, any Affiliate except on an arm's-length basis on terms no less favorable in any material respect to the Borrower or such Subsidiary than could have been obtained from a third party who was not an Affiliate; provided that the foregoing provisions of this Section shall not prohibit (i) the declaration or payment of any lawful dividend or other payment ratably in respect of all of its capital stock of the relevant class or (ii) transactions entered into in the ordinary course of business with joint ventures in which the Borrower has a direct or indirect interest to the extent the Borrower has determined in its reasonable judgment that the business purpose achieved by such transactions renders the terms thereof reasonable.

Each Agent shall have the same rights and powers under the Loan Documents as any other Lender and may exercise or refrain from exercising the same as though it were not an Agent, and each Agent and its Affiliates may engage in any kind of business with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not an Agent hereunder.

SECTION 7.3. Action by Administrative Agent. The obligations of the Administrative Agent hereunder are only those expressly set forth herein.

ARTICLE 8
CHANGE IN CIRCUMSTANCE

SECTION 8.1. Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Fixed Rate Loan:

(a) the Administrative Agent is advised by the Euro-Dollar Reference Lenders that deposits in dollars (in the applicable amounts) are not being offered to the Euro-Dollar Reference Lenders in the relevant market for such Interest Period, or

(b) in the case of a Committed Borrowing, Lenders having 50% or more of the aggregate amount of the Commitments advise the Administrative Agent that the London Interbank Offered Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Lenders of funding their Euro-Dollar Loans for such Interest Period, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist (which notice the Administrative Agent shall deliver immediately upon its becoming aware thereof), (i) the obligations of the Lenders to make Euro-Dollar Loans or to continue or convert outstanding Loans as or into Euro-Dollar Loans shall be suspended and (ii) each outstanding Euro-Dollar Loan shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto. Unless the Borrower notifies the Administrative Agent at least two Domestic Business Days before the date of any Fixed Rate Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, (i) if such Fixed Rate Borrowing is a Committed Borrowing, such Borrowing shall instead be made as a Base Rate Borrowing and (ii) if such Fixed Rate Borrowing is a Money Market LIBOR Borrowing, the Money Market LIBOR Loans comprising such Borrowing shall bear interest for each day from and including the first day to but excluding the last day of the Interest Period applicable thereto at the Base Rate for such day.

SECTION 8.2. Illegality. If, on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Lender (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Lender shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Lenders and the Borrower, whereupon until such Lender notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist (which notice such Lender shall give immediately upon its becoming aware thereof), the obligation of such Lender to make Euro-Dollar Loans, or to convert outstanding Loans into Euro-Dollar Loans, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Lender shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. If such notice is given, each Euro-Dollar Loan of such Lender then outstanding shall be converted to a Base Rate Loan either (a) on the last day of the then current Interest Period applicable to such Euro-Dollar Loan if such Lender may lawfully continue to maintain and fund such Loan to such day or (b) immediately if such Lender shall determine that it may not lawfully continue to maintain and fund such Loan to such day.s

SECTION 8.3. Increased Cost and Reduced Return. (a) If on or after (x) the date upon which a financial institution becomes a Lender under this Agreement, in the case of any Committed Loan or any obligation to make Committed Loans or (y) the date of the related Money Market Quote, in the case of any Money Market Loan, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve, special deposit, insurance assessment or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding, with respect to any Euro-Dollar Loan, any such requirement with respect to which such Lender is entitled to compensation during the relevant Interest Period under Section 2.7) against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Applicable Lending Office) or shall impose on any Lender (or its Applicable Lending Office) or the London interbank market any other condition affecting its Fixed Rate Loans or its obligation to make Fixed Rate Loans, and the result of any of the foregoing is to increase the cost to such Lender (or its Applicable Lending Office) of making or maintaining any Fixed Rate Loan, or to reduce the amount of any sum received or receivable by such Lender (or its Applicable Lending Office) under this Agreement with respect thereto, by an amount deemed by such Lender to be material, then, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction.

(b) If any Lender shall have determined that, after the date upon which such party shall have become a Lender under this Agreement, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital of such Lender (or its Parent) as a consequence of such Lender's obligations hereunder to a level below that which such Lender (or its Parent) could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender (or its Parent) for such reduction.

(c) Each Lender will promptly notify the Borrower and the Administrative Agent of any event, past or prospective, of which it haledge which will entitle such Lender to compensation pursuant to this Section, or which such Lender believes is reasonably likely to entitle such Lender to compensation pursuant to this Section, and will designate a different Applicable L on and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. A certificate of any Lender claiming compensation under this Section (for itself or for a Participant) and setting forth the additional amount or amounts to be paid to it hereunder and indicating in reasonable detail the computation thereof shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

(d) The Borrower shall not be liable pursuant to this Section to any Lender to compensate it for any cost or reduction incurred or suffered more than 45 days before receipt by the Borrower of a notice from such Lender referring to the event that gave rise to such cost or reduction.

(e) This Section 8.3 shall not require the Borrower to reimburse any Lender for any Taxes or Other Taxes which are otherwise covered by the payment of additional amounts or the indemnity set forth in Section 8.4(b) or (c), respectively.

SECTION 8.4. Taxes. (a) For the purposes of this Section 8.4 the following terms have the following meanings:

"Taxes" means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by the Borrower pursuant to this Agreement or under any Note, and all interest, additions to tax or penalties with respect thereto, excluding (i) in the case of each Lender (or Participant) and the Administrative Agent, taxes imposed on its income, and franchise, branch profits or similar taxes imposed on it, by a jurisdiction under the laws of which such Lender or the Administrative Agent (as the case may be) is organized or located or in which its principal executive office is located or, in the case of each Lender (or Participant), in which its Applicable Lending Office is located and (ii) in the case of each Lender (or Participant), any withholding tax imposed on such payments but only to the extent that such Lender (or Participant) is subject to withholding tax at the time such Lender (or Participant) first becomes a party to this Agreement (or designates a new Applicable Lending Office) or is attributable to such Lender's (or Participant's) failure or inability to comply with Section 8.4(d).

"Other Taxes" means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or levies, which arise from any payment made pursuant to this Agreement or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note.

(b) Any and all payments by the Borrower to or for the account of any Lender or the Administrative Agent hereunder or under any Note shall be made without withholding or deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be required by law to deduct any Taxes or Other Taxes from any such payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 9.1, the original or a certified copy of a receipt evidencing payment thereof.

(c) The Borrower agrees to indemnify each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section) paid by such Lender or the Administrative Agent (as the case may be) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto; provided, however, that the Borrower shall not be required to indemnify any Lender or the Administrative Agent under this Section 8.4 for any liability arising as a result of such Lender's or Administrative Agent's willful misconduct or gross negligence. This indemnification shall be paid within 30 days after such Lender or the Administrative Agent (as the case may be) makes written demand therefor (which demand shall identify the nature and the amount of Taxes and Other Taxes for which indemnification is being sought).

(d) Each Lender (or Participant) that is not a "U.S. Person" as defined in Section 7701(a)(30) of the Internal Revenue Code (a "Non-U.S. Lender") on or prior to the date of its execution and delivery of this Agreement in the case of each Lender listed on the signature pages hereof (or, in the case of any Participant, on or before the date such Participant purchases the related participation) and on or prior to the date on which it becomes a Lender in the case of each other Lender, and from time to time thereafter if requested in writing by the Borrower (but only so long as such Non-U.S. Lender remains lawfully able to do so), shall provide the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) with two copies of either Internal Revenue Service Form W-8BEN or Form W-8ECI (or successor forms), or, in the case of a Non-U.S. Lender claiming exemption from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code with respect to payments of "portfolio interest", a Form W-8BEN, or any successor form prescribed by the Internal Revenue Service, and a certificate representing that such Non-U.S. Lender is not a bank for purposes of Section 881(c)(3)(A) of the Internal Revenue Code, is not a 10 percent shareholder of the Borrower (within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code) and is not a "controlled foreign corporation" related to the Borrower (within the meaning of Section 881(c)(3)(C) of the Internal Revenue Code), properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S. Federal withholding tax on payments by the Borrower under this Agreement . Each Non-U.S. Lender further agrees (but only so long as such Non-U.S. Lender is lawfully able to do so) to deliver to the Borrower and the Administrative Agent duly completed copies of the above-mentioned Internal Revenue Service forms on or before the earlier of (i) the date that is 30 days before the date that any such form expires or becomes obsolete or otherwise is required to be resubmitted as a condition to obtaining an exemption from withholding of U.S. federal income tax and (ii) 30 days after the occurrence of any event which would require a change in the most recent form previously delivered to the Borrower and the Administrative Agent.

(e) For any period with respect to which a Lender (or Participant) has failed to provide the Borrower or the Administrative Agent with the appropriate form or certificate pursuant to Section 8.4(d) (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which such form or certificate originally was required to be provided), or with respect to which any representation or certification on any such form or certificate is, or proves to be, materially incorrect, false or misleading when so made such Lender (or Participant) shall not be entitled to receive additional amounts or indemnification under Section 8.4(b) or (c), respectively, with respect to Taxes imposed by the United States and such Lender (or Participant) shall indemnify and reimburse the Borrower for any Taxes or Other Taxes which were required to be withheld but which were not withheld as a result of such Lender's (or Participant's) materially incorrect, false or misleading representations or certifications; provided that if a Lender (or Participant), which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps (at such Lender's (or Participant's) cost and expense) as such Lender (or Participant) shall reasonably request to assist such Lender (or Participant) to recover such Taxes.

(f) If the Borrower is required to pay additional amounts to or for the account of any Lender pursuant to this Section, then (i) such Lender will change the jurisdiction of its Applicable Lending Office if, in the judgment of such Lender, such change (x) will eliminate or reduce any such additional payment which may thereafter accrue and (y) is not otherwise disadvantageous to such Lender or (ii) if such Lender does not change the jurisdiction of its Applicable Lending Office, the Borrower shall have the right to designate a substitute lender or lenders pursuant to Section 8.6 hereof.

(g) Upon the reasonable request of the Borrower, and at the Borrower's expense, each Lender shall use reasonable efforts to cooperate with the Borrower with a view to obtain a refund of any Taxes or Other Taxes for which the Borrower has indemnified such Lender under this Section 8.4 if obtaining such refund would not, in the sole judgment of such Lender, be disadvantageous to such Lender. If a Lender shall receive a refund from a taxing authority of any Taxes or other Taxes paid by the Borrower pursuant to subsection (b) or (c) above, such Lender shall promptly pay to the Borrower the amount so received without interest (other than interest received from the taxing authority with respect to such refund) and net of out-of-pocket expenses; provided that such Lender shall only be required to pay to the Borrower such amounts as such Lender in its sole discretion determines are attributable to Taxes paid by the Borrower. In the event such Lender or the Administrative Agent is required to repay the amount of such refund (including interest, if any), the Borrower, upon the request of such Lender or the Administrative Agent (as the case may be), agrees to promptly return to such Lender or the Administrative Agent the amount of such refund and interest, if any (plus penalties, interest and other charges imposed in connection with the repayment of such amounts by such Lender or the Administrative Agent).

(h) Notwithstanding the foregoing, nothing in this Section 8.4 shall be construed to (i) entitle the Borrower or any other Persons (A) to any information determined by any Lender or the Administrative Agent, in its sole discretion, to be confidential or proprietary information of such Lender or the Administrative Agent unrelated to matters specifically related to this Section 8.4, (B) to any tax or financial information of any Lender or the Administrative Agent unrelated to matters specifically related to this Section 8.4 or (C) to inspect or review any books and records of any Lender or the Administrative Agent unrelated to matters specifically related to this Section 8.4, or (ii) interfere with the rights of any Lender or the Administrative Agent to conduct its fiscal or tax affairs in such manner as it deems fit.

SECTION 8.5. Base Rate Loans Substituted for Affected Fixed Rate. If (i) the obligation of any Lender to make, or convert outstanding Loans to, Euro-Dollar Loans has been suspended pursuant to Section 8.2 or (ii) any Lender has demanded compensation under Section 8.3(a) or 8.4, or the Borrower is required to make any additional payments under Section 8.4 in respect of any payments to any Lender, in either case with respect to its Euro-Dollar Loans, and the Borrower shall, by at least five Euro-Dollar Business Days' prior notice to such Lender through the Administrative Agent, have elected that the provisions of this Section shall apply to such Lender, then, unless and until such Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer apply:

(a) all Loans which would otherwise be made by such Lender as (or continued as or converted into) Euro-Dollar Loans shall instead be Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Fixed Rate Loans of the other Lenders), and

(b) after each of its Euro-Dollar Loans has been repaid (or converted to a Base Rate Loan), all payments of principal which would otherwise be applied to repay such Fixed Rate Loans shall be applied to repay its Base Rate Loans instead.

If such Lender notifies the Borrower that the circumstances giving rise to such notice no longer apply, the principal amount of each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Lenders.

SECTION 8.6. Substitution of Lender. If any Lender has demanded compensation under Section 8.3 or 8.4, the Borrower is required to make any additional payments under Section 8.4 in respect of any payment to any Lender or any Lender defaults in any of its obligations to make any Loan, the Borrower shall have the right to designate a substitute lender or lenders reasonably acceptable to the Administrative Agent (which may be one or more of the Lenders) to purchase the Loans and assume the Commitments of such Lender and each Lender agrees in such event, if the Borrower so designates a substitute or substitutes, it will sell its Loans and assign its rights under this Agreement to such a substitute or substitutes as soon as reasonably possible (and in any event within 30 days) after such designation on substantially the terms set forth in Exhibit D for a payment equal to the principal amount of its Loans plus all interest on such Loans and all facility fees accrued but unpaid to but excluding the date of such payment plus any loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), in connection with such payment, including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin for the period after any such payment, as reasonably determined by it.

Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communications pursuant to procedures approved by the Administrative Agent (upon any such procedures' approval, the Administrative Agent shall provide notice thereof to the applicable Lender); provided that the foregoing shall not apply to notices pursuant to Article 2 unless otherwise agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it prior to such communication (upon any such procedures' approval, the Administrative Agent shall provide notice thereof to the Lenders); provided that approval of such procedures may be limited to particular notices or communications.

SECTION 9.2. No Waivers. No failure or delay by any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies provided in the Loan Documents shall be cumulative and not exclusive of any rights or remedies provided by law.

SECTION 9.3. Expenses; Indemnification. (a) The Borrower shall pay (i) all reasonably incurred out-of-pocket expenses of the Administrative Agent, including fees and disbursements of special counsel for the Administrative Agent, in connection with the preparation and administration of this Agreement, any waiver or consent hereunder or any amendment hereof or any Default or alleged Default hereunder and (ii) if an Event of Default occurs, all out-of-pocket expenses incurred by the Administrative Agent and each Lender, including fees and disbursements of counsel, in connection with such Event of Default and collection, bankruptcy, insolvency and other enforcement proceedings resulting therefrom.

(b) The Borrower agrees to indemnify the Administrative Agent and each Lender, their respective affiliates and the respective directors, officers, agents, employees and advisors of the foregoing (each an "Indemnitee") and hold each Indemnitee harmless from and against any and all liabilities, losses, actions, judgments, suits, damages, costs and expenses of any kind, including, without limitation the reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding (whether or not such Indemnitee shall be designated a party thereto) brought or threatened relating to or arising out of this Agreement or any actual or proposed use of proceeds of Loans hereunder (all the foregoing, collectively, the "indemnified liabilities"); provided that no Indemnitee shall have the right to be indemnified hereunder for indemnified liabilities found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from such Indemnitee's gross negligence or willful misconduct.

SECTION 9.4. Sharing of Set-Offs. (a) Each Lender agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Loan payable to it which is greater than the proportion received by any other Lender in respect of the aggregate amount of principal and interest due with respect to any Loan payable to such other Lender, the Lender receiving such proportionately greater payment shall purchase such participations in the Loans payable to the other Lenders, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Loans shall be shared by the Lenders pro rata; provided that nothing in this Section shall impair the right of any Lender to exercise any right of set-off or counterclaim it may have against the Borrower and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than its indebtedness under the Loan Documents.

(b) If an Event of Default shall have occurred and be continuing, each Lender and each of its Lender Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Lender Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of set-off) which such Lender may have.

SECTION 9.5. Amendments and Waivers. Any provision of this Agreement or any Note may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Lenders (and, if the rights or duties of the Administrative Agent are affected thereby, by the Administrative Agent); provided that no such amendment or waiver shall, (a) unless signed by each Lender directly affected thereby, (i) increase any Commitment of such Lender or subject such Lender to any additional obligation, (ii) reduce the principal of or rate of interest on any Committed Loan or any fees hereunder or (iii) postpone the date fixed for any payment of principal of or interest on any Committed Loan or any fees hereunder or for the termination of any Commitment or (b) unless signed by all the Lenders, change the percentage of the Lenders which shall be required for the Lenders to take any action under this Section or any other provision of the Loan Documents, and provided further that no such amendment or waiver shall reduce the principal of or rate of interest on any Money Market Loan or postpone the date fixed for any payment of principal of or interest on any Money Market Loan unless signed by the Lender which has made such Money Market Loan.

SECTION 9.6. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, provided that the Borrower may not assign or otherwise transfer any of its rights under this Agreement (and any attempted assignment or transfer shall be null and void) except as contemplated by Section 5.9 or with the prior written consent of all Lenders.

(b) Any Lender other than any Conduit Lender may at any time grant to one or more banks or other entities (other than the Borrower or the Borrower's Affiliates or Subsidiaries) (each a "Participant") participating interests in any or all of its Commitments or Loans. In the event of any such grant by a Lender of a participating interest to a Participant, whether or not upon notice to the Borrower and the Administrative Agent, such Lender shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide that such Lender shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that such Lender will not agree to any modification, amendment or waiver of this Agreement described in clause (a)(i), (ii) or (iii) of Section 9.5 without the consent of the Participant. The Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Section 2.7 and Article 8 with respect to its participating interest. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection (b).

(c) Any Lender other than any Conduit Lender may at any time assign to any Lender or Lender Affiliate or any bank or other entity (other than the Borrower or the Borrower's Affiliates or Subsidiaries) (each an "Assignee") all or a portion of its rights and obligations under this Agreement, and such Assignee shall assume such rights and obligations, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D hereto executed by such Assignee and such transferor Lender; provided that after giving effect to such assignment to an Assignee (other than any Lender or any Lender Affiliate), (x) the Commitment (or, if the Commitments shall have terminated, the aggregate principal amount of the Loans) of the assignor Lender (together with its Lender Affiliates) shall be either zero or $10,000,000 or more, unless otherwise agreed by the Borrower and the Administrative Agent and (y) the Commitment (or, if the Commitments shall have terminated, the aggregate principal amount of the Loans) of the Assignee (together with its Affiliates) shall be $10,000,000 or more, unless otherwise agreed by the Borrower and the Administrative Agent. For purposes of the proviso contained in the preceding sentence, the amount described therein shall be aggregated in respect of each Lender and its Lender Affiliates, if any. Each such assignment shall be made with (and subject to) the subscribed consent of the Borrower and the Administrative Agent (which shall not, in either case, be unreasonably withheld); provided that if an Assignee is a Lender Affiliate or is a Lender immediately prior to such assignment, or if at the time an Event of Default shall have occurred and be continuing, no such consent shall be required. Upon execution and delivery of such instrument, recording of such instrument as provided in Section 2.16(a), obtainment of the foregoing required consents (if any) and payment by such Assignee to such transferor Lender of an amount equal to the purchase price agreed between such transferor Lender and such Assignee, such Assignee shall be a Lender party to this Agreement and shall have all the rights and obligations of a Lender with a Commitment (or, if the Commitments shall have terminated, Loans in an aggregate principal amount) as set forth in such instrument of assumption, and the transferor Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. In connection with any such assignment, the transferor Lender shall pay to the Administrative Agent an administrative fee for processing such assignment in the amount of $3,500. If the Assignee is not incorporated under the laws of the United States of America or a state thereof, it shall, prior to the first date on which interest or fees are payable hereunder for its account, deliver to the Borrower and the Administrative Agent certification as to exemption from deduction or withholding of any United States federal income taxes in accordance with Section 8.4. Notwithstanding the foregoing, any Conduit Lender may assign at any time to its designating Lender hereunder without the consent of the Borrower or the Administrative Agent any or all of the Loans it may have funded hereunder and pursuant to its designation agreement and without regard to the limitations set forth in the first sentence of this Section 9.6(c).

(d) Any Lender may at any time assign all or any portion of its rights under this Agreement to a Federal Reserve Bank. No such assignment shall release the transferor Lender from its obligations hereunder.

(e) No Assignee, Participant or other transferee of any Lender's rights shall be entitled to receive any greater payment under Section 8.3 or 8.4, (and the Borrower shall not incur any greater liability for Taxes or Other Taxes pursuant to Section 8.4), than such Lender would have been entitled to receive with respect to the rights transferred (or than the Borrower was liable for with respect to the transferor Lender), unless such transfer is made (i) by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such Lender to designate a different Applicable Lending Office under certain circumstances or (ii) at a time when the circumstances giving rise to such greater payment did not exist.

(f) Each of the Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by such Conduit Lender; provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such period of forbearance.

SECTION 9.7. Governing Law; Submission to Jurisdiction, WAIVER OF JURY TRIAL. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, including General Obligations Laws 5-1401 and 5-1402. Each of the parties hereto hereby submits to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in New York City for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each of the parties hereto irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. EACH OF THE BORROWER, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 9.8. Counterparts; Integration; Effectiveness. (a) This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signature thereto and hereto were upon the same instrument. The Loan Documents constitute the entire agreement and understanding among the parties hereto and supersede any and all prior agreements and understandings, oral or written, relating to the subject matter hereof.

(b) This Agreement shall become effective on the date that the Administrative Agent shall have received counterparts hereof signed by each of the parties hereto (or, in the case of any party as to which an executed counterpart shall not have been received, receipt by the Administrative Agent in form reasonably satisfactory to it of telegraphic, electronic mail or other written confirmation from such party of execution of a counterpart hereof by such party).

SECTION 9.9. Confidentiality. The Administrative Agent and each Lender agrees to keep any information delivered or made available by the Borrower pursuant to the Loan Documents confidential from anyone other than persons employed or retained by such Lender and its Lender Affiliates who are engaged in evaluating, approving, structuring or administering the credit facility contemplated hereby; provided that nothing herein shall prevent the Administrative Agent or any Lender from disclosing such information (a) to any other Lender or to the Administrative Agent, (b) to any other Person if reasonably incidental to the administration of the credit facility contemplated hereby, (c) upon the order of any court or administrative agency, (d) upon the request or demand of any regulatory agency or authority, (e) which had been publicly disclosed other than as a result of a disclosure by the Administrative Agent or any Lender prohibited by this Agreement, (f) in connection with any litigation to which the Administrative Agent, any Lender or its subsidiaries or Parent may be a party, (g) to the extent necessary in connection with the exercise of any remedy hereunder, (h) to such Lender's or the Administrative Agent's legal counsel and independent auditors and (i) subject to provisions substantially similar to those contained in this Section, to any actual or proposed Participant or Assignee.

SECTION 9.10. Termination. This Agreement shall terminate upon the termination of all Commitments and repayment in full of the aggregate outstanding principal amount of the Loans, accrued interest thereon, and all fees and expenses and other amounts due and payable at such time; provided that the provisions of Sections 7.6, 8.3, 8.4 and 9.3 shall survive such termination.

SECTION 9.11. Collateral. Each of the Lenders represents to the Administrative Agent and each of the other Lenders that it in good faith is not relying upon any "margin stock" (as defined in the Margin Regulations) as collateral in the extension or maintenance of the credit provided for in this Agreement. Each of the Lenders acknowledges that the proceeds of the Loans hereunder will be used as described in Section 5.10.

SECTION 9.12. Representations of Lenders. (a) Each of the Lenders represents and warrants to the Borrower that it is a corporation or association duly incorporated or organized and validly existing under the laws of its jurisdiction of incorporation or organization, as the case may be.

(b) Each of the Lenders represents and warrants to the Borrower that this Agreement constitutes a valid and binding agreement of it enforceable against it in accordance with the terms hereof subject to (i) applicable receivership, insolvency, reorganization, moratorium and other laws affecting the rights of creditors of banks or other institutions generally from time to time in effect and (ii) equitable principles of general applicability.

SECTION 9.13. USA PATRIOT Act. Each Lender which is subject to Section 326 of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the "Act"), hereby notifies the Borrower that, pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.

For purposes of this Grid, the following terms have the following meanings, subject to the final paragraph of this Grid:

"Level I Status" exists at any date if, at such date, the Borrower's senior unsecured long-term debt is rated A/A2 or higher.

"Level II Status" exists at any date if, at such date, the Borrower's senior unsecured long-term debt is rated A-/A3.

"Level III Status" exists at any date if, at such date, the Borrower's senior unsecured long-term debt is rated BBB+/Baa1.

"Level IV Status" exists at any date if, at such date, the Borrower's senior unsecured long-term debt is rated BBB/Baa2.

"Level V Status" exists at any date if, at such date, the Borrower's senior unsecured long-term debt is rated BBB-/Baa3.

"Level VI Status" exists at any date if, at such date, no other Status exists.

"Moody's" means Xxxxx'x Investors Service, Inc or its successor entity.

"S&P" means Standard & Poor's Ratings Services, a division of The XxXxxx-Xxxx Companies, Inc or its successor entity.

"Status" refers to the determination of which of Level I Status, Level II Status, Level III Status, Level IV Status, Level V Status or Level VI Status exists at any date.

"Utilization" means, at any date, the percentage equivalent of a fraction (i) the numerator of which is the aggregate outstanding principal amount of the Committed Loans at such date and (ii) the denominator of which is the aggregate amount of the Commitments at such date. If for any reason any Committed Loans remain outstanding following termination of the Commitments, Utilization shall be deemed to be in excess of 50%.

The credit ratings to be utilized for purposes of this Schedule are those assigned to the senior unsecured long-term debt securities of the Borrower without third-party credit enhancement, and any rating assigned to any other debt security of the Borrower shall be disregarded. In the event of split ratings from Moody's and S&P, (i) if the ratings are one full rating category apart, Status shall be determined by the higher of the two ratings (unless the lower of such two ratings is BB+(Ba1) or lower, in which case Status shall be determined by the lower of such two ratings) and (ii) if the ratings are more than one full rating category apart, Status shall be determined based on the rating at the midpoint between the two ratings, provided that if there is no rating at the midpoint between the two ratings, the higher of the two intermediate ratings (unless the lower of such two ratings is BB+(Ba1) or lower, in which case Status shall be determined by the lower of such two ratings) shall apply (e.g., BBB+/Baa2 results in Level III Status, BBB+/Baa3 and BBB/Baa3 both result in Level IV Status and BBB+/Ba1 results in Level V Status).
