“Allocable CSX/NS Debt” means the allocable portion of any obligation of any CSX/NS Acquisition Sub Entity which would be included as “Debt” of the Borrower if such CSX/NS Acquisition Sub Entity were a Subsidiary of the Borrower, with such allocable portion being equal to a percentage of such obligations equal to the percentage of the capital stock of such CSX/NS Acquisition Sub Entity which is directly or indirectly owned by the Borrower, provided that (a) the Allocable CSX/NS Debt with respect to any obligations which constitute CSX Conrail Debt shall be the entire amount of such obligations, (b) the Allocable CSX/NS Debt with respect to any obligations which constitute NS Conrail Debt shall be zero and (c) the Allocable CSX/NS Debt with respect to any obligations of any CSX/NS Acquisition Sub Entity which would be included as “Debt” of the Borrower if such CSX/NS Acquisition Sub Entity were a Subsidiary of the Borrower and which would be permitted under Sections 6.01(a), 6.01(b), 6.01(c) and 6.01(d) (assuming all CSX/NS Acquisition Sub Entities were Subsidiaries) shall be zero.

“Allocable Railroad Revenues” means a percentage of any Railroad Revenues of any CSX/NS Entity equal to the percentage of the capital stock of such CSX/NS Entity which is directly or indirectly owned by the Borrower, provided that the Allocable Railroad Revenues with respect to the Railroad Revenues of any CSX Conrail Subsidiary shall be the entire amount of such Railroad Revenues.

“Alternate Base Rate” means, for any day, a rate per annum equal to the greater of (a) the Prime Rate in effect on such day and (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%.

“Applicable Percentage” means, with respect to any Lender, the percentage of the total Commitments represented by such Lender’s Commitment. If the Commitments have terminated or expired, the Applicable Percentages shall be determined based upon the Commitments most recently in effect, giving effect to any assignments.

	Index Debt Ratings (S&P/Xxxxx’x)	Facility Fee (basis points per annum)	LIBOR Margin (basis points per annum)
Category 1	A/A2 or higher	11	19.0

Category 4	BBB/Baa2	11	51.5
Category 5	BBB-/Baa3	11	64.0

For purposes of the foregoing, (i) if neither Xxxxx’x nor S&P shall have in effect a rating for the Index Debt (other than by reason of the circumstances referred to in the last two sentences of this definition), then both such rating agencies shall be deemed to have established a rating in Category 6; (ii) if only one of Xxxxx’x or S&P shall have in effect a rating for the Index Debt, then the Borrower and the Lenders will negotiate in good faith to agree upon another rating agency to be substituted by an amendment to this Agreement for the rating agency which shall not have a rating in effect, and in the absence of such amendment the Applicable Rate will be determined by reference to the available rating; (iii) if the ratings established or deemed to have been established by Xxxxx’x and S&P for the Index Debt shall fall within different Categories, the Applicable Rate shall be based on the higher of the two ratings unless one of the two ratings is two or more Categories lower than the other, in which case the Applicable Rate shall be determined by reference to the Category next below that of the higher of the two ratings; and (iv) if the ratings established or deemed to have been established by Xxxxx’x and S&P for the Index Debt shall be changed (other than as a result of a change in the rating system of Xxxxx’x or S&P), such change shall be effective as of the date on which it is first announced by the applicable rating agency. Each change in the Applicable Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of Xxxxx’x or S&P shall change, the Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Rate shall be determined by reference to the rating or ratings most recently in effect prior to such change or cessation. If both Xxxxx’x and S&P shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to agree upon a substitute rating agency and to amend the references to specific ratings in this definition to reflect the ratings used by such substitute rating agency, and in the absence of such amendment then both such rating agencies shall be deemed to have established a rating in Category 6.

In the event that any Revolving Loans remain outstanding after the Maturity Date pursuant to Section 2.08(e), (i) to the extent that such Revolving Loans are maintained as Eurodollar Revolving Loans the Applicable Rate with respect to Eurodollar Revolving Loans shall continue to be determined pursuant to the foregoing pricing grid but after giving effect to an increase of 0.25% to each rate specified for each Category on such grid under the heading “LIBOR Margin” and (ii) to the extent that such Revolving Loans are maintained as ABR Revolving Loans and the Applicable Rate for any such Revolving Loans would be determined based on Category 6 had such Revolving Loans then been maintained as Eurodollar Revolving Loans, there shall be an “Applicable Rate” with respect to such ABR Revolving Loans which shall be equal to 0.25%.

The Borrower shall notify the Administrative Agent by telephone, confirmed by telecopy in a form approved by the Administrative Agent, whether and to what extent it has decided to accept or reject each Competitive Bid, in the case of a Eurodollar Competitive Borrowing, not later than 10:30 a.m., New York City time, three Business Days before the date of the proposed Competitive Borrowing and, in the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York City time, on the proposed date of the Competitive Borrowing; provided that (i) the failure of the Borrower to give such notice shall be deemed to be a rejection of each Competitive Bid, (ii) the Borrower shall not accept a Competitive Bid made at a particular Competitive Bid Rate if the Borrower rejects a Competitive Bid made at a lower Competitive Bid Rate, (iii) the aggregate amount of the Competitive Bids

accepted by the Borrower shall not exceed the aggregate amount of the requested Competitive Borrowing specified in the related Competitive Bid Request, (iv) to the extent necessary to comply with clause (iii) above, the Borrower may accept Competitive Bids at the same Competitive Bid Rate in part, which acceptance, in the case of multiple Competitive Bids at such Competitive Bid Rate, shall be made pro rata in accordance with the amount of each such Competitive Bid, and (v) except pursuant to clause (iv) above, no Competitive Bid shall be accepted for a Competitive Loan unless such Competitive Loan is in a minimum principal amount of $5,000,000 and an integral multiple of $1,000,000; provided further that, if a Competitive Loan must be in an amount less than $5,000,000 because of the provisions of clause (iv) above, such Competitive Loan may be for a minimum of $1,000,000 or any integral multiple thereof, and in calculating the pro rata allocation of acceptances of portions of multiple Competitive Bids at a particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be rounded to integral multiples of $1,000,000 in a manner determined by the Borrower. A notice given by the Borrower pursuant to this paragraph shall be irrevocable.

(e) The Administrative Agent shall promptly notify each bidding Lender by telecopy whether or not its Competitive Bid has been accepted (and, if so, the amount and Competitive Bid Rate so accepted), and each successful bidder will thereupon become bound, subject to the terms and conditions hereof, to make the Competitive Loan in respect of which its Competitive Bid has been accepted.

(f) If the Administrative Agent shall elect to submit a Competitive Bid in its capacity as a Lender, it shall submit such Competitive Bid directly to the Borrower at least one quarter of an hour earlier than the time by which the other Lenders are required to submit their Competitive Bids to the Administrative Agent pursuant to paragraph (b) of this Section.

SECTION 2.05. [Intentionally Omitted].

SECTION 2.06. Funding of Borrowings. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request or Competitive Bid Request.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed 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 on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the Federal Funds Effective Rate or (ii)

in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing and the Administrative Agent shall promptly return to the Borrower any amount (including interest) paid by the Borrower to the Administrative Agent pursuant to the immediately preceding sentence, together with any interest thereon paid by such Lender for any day not covered by the Borrower’s payment.

SECTION 2.07. Interest Elections. (a) Each Revolving Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Revolving Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Revolving Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall not apply to Competitive Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Revolving Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Majority Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Revolving Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Revolving Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.08. Expiration, Termination and Reduction of Commitments. (a) Unless previously terminated, the Commitments shall expire on the Maturity Date.

(b) Upon any direct or indirect sale or other disposition of Shares (other than Shares constituting Unrestricted Margin Stock) directly or indirectly beneficially owned by the Borrower (other than (i) to the Borrower’s direct or indirect Subsidiaries, (ii) to any wholly-owned subsidiary of CSX/NS Acquisition Sub so long as the Borrower’s direct or indirect proportionate beneficial ownership of the Shares shall not be reduced as a result thereof, or (iii) to NS or its subsidiaries or any CSX/NS Acquisition Sub Entity in consideration of the acquisition of any assets of Conrail or any of its subsidiaries by the Borrower or any Subsidiary), the Commitments and the Commitments (as defined in the Five-Year Credit Agreement) shall be automatically reduced, on a ratable basis, in an aggregate amount equal to 100% of the Net Cash Proceeds to the Borrower and the Subsidiaries of any such sale or other disposition of Shares (other than Shares constituting Unrestricted Margin Stock). Each such reduction shall become effective on the fifth Business Day following receipt by the Borrower or any Subsidiary, as the case may be, of any such Net Cash Proceeds.

(c) The Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $10,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the Aggregate Outstanding Extensions of Credit would exceed the total Commitments.

(d) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (c) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not

satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

(e) The Borrower may elect to extend the maturity of all or any portion of the Revolving Loans outstanding on the Maturity Date to the date which is the first anniversary of the Maturity Date by giving written notice of such election to the Administrative Agent at least 30 days prior to the Maturity Date.

SECTION 2.09. Repayment of Loans; Evidence of Debt. (a) Subject to Section 2.08(e), the Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan on the Maturity Date and (ii) to the Administrative Agent for the account of each applicable Lender the then unpaid principal amount of each Competitive Loan on the last day of the Interest Period applicable to such Loan.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. In case of any discrepancy between the entries made by the Administrative Agent pursuant to this paragraph and the entries made by any Lender pursuant to paragraph (b) of this Section, such Lender’s entries shall be considered correct, in the absence of manifest error.

(d) In case of any dispute, action or proceeding relating to any Loan, the entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e) Any Lender may request of the Borrower that (i) Revolving Loans made by it be evidenced by a promissory note, substantially in the form of Exhibit B-1 (a “Revolving Loan Note”) and (ii) Competitive Loans made by it be evidenced by a promissory note, substantially in the form of Exhibit B-2 (a “Competitive Loan Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender promissory notes in such forms payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns). Thereafter, the Loans evidenced by such promissory notes and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such forms payable to the order of the payee named therein (or, if any such promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.10. Optional and Mandatory Prepayment of Loans. (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section; provided that the Borrower shall not have the right to prepay any Competitive Loan without the prior written consent of the Lender thereof.

(b) The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment to be made pursuant to paragraph (a) of this Section (i) in the case of prepayment of a Eurodollar Revolving Borrowing, not later than 11:00 a.m., New York City time, three Business Days before the date of prepayment or (ii) in the case of prepayment of an ABR Revolving Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.08, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.08. Promptly following receipt of any such notice relating to a Revolving Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Revolving Borrowing shall be in an amount that would be permitted in the case of an advance of a Revolving Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Revolving Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by payment of accrued interest to the extent required by Section 2.12.

(c) If, following any reduction of the total Commitments in connection with any sale or other disposition of Shares by the Borrower or any Subsidiary, the Aggregate Outstanding Extensions of Credit exceed the total Commitments, the Borrower shall, without notice or demand, immediately repay Revolving Loans in an aggregate principal amount equal to the lesser of (i) the amount of such excess and (ii) the aggregate principal amount of Revolving Loans then outstanding, together with interest accrued to the date of such payment or prepayment on the principal so prepaid and any amounts payable under Section 2.15 in connection therewith. To the extent that after giving effect to any prepayment of Revolving Loans required by the preceding sentence, the Aggregate Outstanding Extensions of Credit still exceed the total Commitments, the Borrower shall, without notice or demand, immediately deposit in a Cash Collateral Account upon terms reasonably satisfactory to the Administrative Agent an amount equal to the amount of such remaining excess. The Administrative Agent shall apply any cash deposited in the Cash Collateral Account (to the extent thereof) to repay the principal of each Competitive Loan on the date such principal becomes due and payable hereunder, provided that the Administrative Agent shall release to the Borrower from time to time such portion of the amount on deposit in the Cash Collateral Account which is equal to the amount by which the total Commitments at such time plus the amount on deposit in the Cash Collateral Account exceeds the Aggregate Outstanding Extensions of Credit at such time. “Cash Collateral Account” means an account, in the name of the Administrative Agent for the benefit of the Lenders, established by the Borrower with the Administrative Agent and over which the Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal for application in accordance with this Section.

SECTION 2.11. Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee, which shall accrue at the Applicable Rate on the daily amount of the Commitment of such Lender (whether used or unused) during the period from and including the Closing Date to but excluding the date on which such Commitment expires or is terminated; provided that, if such Lender continues to have any Revolving Credit Exposure after its Commitment terminates, then such facility fee shall continue to accrue on the daily amount of such Lender’s Revolving Credit Exposure from and including the date on which its Commitment terminates to but excluding the date on which such Lender ceases to have any Revolving Credit Exposure. Accrued facility fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof; provided that any facility fees accruing after the date on which the Commitments terminate shall be payable on demand. All facility fees shall be computed on the basis of a year of 365 (or 366 in the case of a leap year) days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a utilization fee, which shall accrue at a rate per annum of 0.125% on the daily amount of such Lender’s Revolving Credit Exposure, for any periods during which (i) the sum of (A) the Aggregate Outstanding Extensions of Credit hereunder plus (B) the Aggregate Outstanding Extensions of Credit (as defined in the Five-Year Credit Agreement) under the Five-Year Credit Agreement exceeds (ii) 50% of the sum of (A) the aggregate amount of Commitments hereunder plus (B) the aggregate amount of Commitments (as defined in the Five-Year Credit Agreement) under the Five-Year Credit Agreement. Accrued utilization fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first applicable such date to occur after the date hereof. All utilization fees shall be computed on the basis of a year of 365 (or 366 in the case of a leap year) days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, in the case of facility fees and utilization fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

SECTION 2.12. Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate (if any).

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum equal to (i) in the case of a Eurodollar Revolving Loan, the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate or (ii) in the case of a Eurodollar Competitive Loan, the LIBO Rate for the Interest Period in effect for such Borrowing plus (or minus, as applicable) the Margin applicable to such Loan.

(d) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, from and including the date such amount shall become due, but excluding the date such amount shall be paid in accordance with Section 2.17, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided above or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided above.

(e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan; provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, (iii) in the event of any conversion of any Eurodollar Revolving Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion and (iv) all accrued interest shall be payable upon termination of the Commitments.

(f) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be presumptively correct absent manifest error.

SECTION 2.13. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be presumptively correct, absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Majority Lenders (or, in the case of a Eurodollar Competitive Loan, the Lender that is required to make such Loan) that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing

to, or continuation of any Revolving Borrowing as, a Eurodollar Borrowing shall be ineffective, (ii) if any Borrowing Request requests a Eurodollar Revolving Borrowing, such Borrowing shall be made as an ABR Borrowing and (iii) any request by the Borrower for a Eurodollar Competitive Borrowing shall be ineffective; provided that (A) if the circumstances giving rise to such notice do not affect all the Lenders, then requests by the Borrower for Eurodollar Competitive Borrowings may be made to Lenders that are not affected thereby and (B) if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

SECTION 2.14. Increased Costs. (a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans or Fixed Rate Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or Fixed Rate Loan or to reduce the amount of any sum received or receivable by such Lender hereunder in respect of such Loan by an amount deemed by such Lender to be material, then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b) If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c) A certificate of a Lender setting forth the amount or amounts (including the basis therefor and the calculation thereof) necessary to compensate such Lender or its holding company as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be presumptively correct absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than three months prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided

further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the three-month period referred to above shall be extended to include the period of retroactive effect thereof.

(e) Notwithstanding the foregoing provisions of this Section, a Lender shall not be entitled to compensation pursuant to this Section in respect of any Competitive Loan if the Change in Law that would otherwise entitle it to such compensation shall have been publicly announced prior to submission of the Competitive Bid pursuant to which such Loan was made.

SECTION 2.15. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan or Fixed Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice is permitted to be revocable under Section 2.10(b) and is revoked in accordance herewith), (d) the failure to borrow any Competitive Loan after accepting the Competitive Bid to make such Loan, or (e) the assignment of any Eurodollar Loan or Fixed Rate Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.18, then, in any such event, the Borrower shall compensate each Lender for the loss and the actual cost and expense attributable to such event. In the case of a Eurodollar Loan, the loss to any Lender attributable to any such event shall be deemed to include an amount reasonably determined by such Lender to be equal to the excess, if any, of (i) the amount of interest that such Lender would pay for a deposit equal to the principal amount of such Loan for the period from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest rate payable on such deposit were equal to the Adjusted LIBO Rate (in the case of a Eurodollar Revolving Loan) or the LIBO Rate (in the case of a Eurodollar Competitive Loan) for such Interest Period, over (ii) the amount of interest that such Lender would earn on such principal amount for such period if such Lender were to invest such principal amount for such period at the interest rate that would be bid by such Lender (or an Affiliate of such Lender) for dollar deposits from other banks in the eurodollar market at the commencement of such period. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive (including the basis therefor and the calculation thereof) pursuant to this Section shall be delivered to the Borrower and shall be presumptively correct absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.16. Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (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) the Administrative Agent or each Lender (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 and (iii) the Borrower

shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent and each Lender, within 30 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent or such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto to the extent such penalties, interest and expenses shall not result from any action or inaction on the part of the Administrative Agent or such Lender, as the case may be, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability (including the basis therefor and the calculation thereof) delivered to the Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be presumptively correct absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Unless after the date any Foreign Lender becomes a Lender hereunder there is a Change in Law which would prevent such Foreign Lender from duly completing and delivering such documentation and such Foreign Lender so advises the Administrative Agent and the Borrower, such Foreign Lender shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit payments made under this Agreement to be made without withholding.

(f) If the Borrower determines in good faith that a reasonable basis exists for contesting a Tax, the relevant Lender or the Administrative Agent, as applicable, shall cooperate with the Borrower in challenging such Tax at the Borrower’s expense if requested by the Borrower. If any Lender or the Administrative Agent, as applicable, obtains a credit against or receives a refund or reduction (whether by way of direct payment or by offset) of any Tax for which payment has been made pursuant to this Section, which credit, refund or reduction in the good faith judgment of such Lender or the Administrative Agent, as the case may be, (and without any obligation to disclose its tax records) is allocable to such payment made under this Section, the amount of such credit, refund or reduction (together with any interest received thereon) promptly shall be paid to the Borrower to the extent payment has been made in full by the Borrower pursuant to this Section.

SECTION 2.17. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or under Section 2.14, 2.15 or 2.16, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or

counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, except that payments pursuant to Sections 2.14, 2.15, 2.16 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension at the same applicable rate. All payments hereunder shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, to pay interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such

parties, and (ii) second, to pay principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Revolving Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may, subject to Section 9.08, exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such

amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Federal Funds Effective Rate.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.06(b) or 2.17(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.18. Mitigation Obligations; Replacement of Lenders. (a) If any Lender or a Participant in such Lender’s Loans requests compensation under Section 2.14, or if the Borrower is required to pay any additional amount to any Lender or a Participant in such Lender’s Loans or any Governmental Authority for the account of any Lender or Participant pursuant to Section 2.16, then such Lender or Participant shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the reasonable judgment of such Lender or Participant, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.14 or 2.16, as the case may be, in the future and (ii) would not subject such Lender or Participant to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender or Participant. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender or Participant in connection with any such designation or assignment. Without limiting the generality of the foregoing, each Lender and Participant shall use all reasonable efforts to mitigate the effect upon the Borrower of any increased capital requirement and shall assess any cost related to such increased capital on a nondiscriminatory basis among the Borrower and other borrowers of such Lender or Participant to which such cost applies and such Lender or Participant shall not be entitled to be compensated for any increased capital requirement unless it is, as a result of such law, regulation, guideline or request, such Lender’s or Participant’s policy generally to seek to exercise such rights, where available, against other borrowers of such Lender or Participant.

(b) If any Lender or a Participant in such Lender’s Loans requests compensation under Section 2.14, or if the Borrower is required to pay any additional amount to any Lender or Participant or any Governmental Authority for the account of any Lender or Participant pursuant to Section 2.16, or if any Lender defaults in its obligation to fund Loans hereunder, or if any Lender shall have a credit rating of C/D (or its equivalent) or lower by Thomson BankWatch, Inc. (or any successor thereto), then the Borrower shall have the right, at its sole expense, upon notice to such Lender and the Administrative Agent, to require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement (other than any outstanding Competitive Loans held by it) to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, each Issuing Bank) which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans (other than Competitive 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) and (iii) in the case of any such assignment resulting from a claim for

compensation under Section 2.14 or payments required to be made pursuant to Section 2.16, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

ARTICLE VII

Events of Default

If any of the following events (“Events of Default”) shall occur:

(a) the Borrower shall fail to pay any principal of any Loan when and as the same shall become due and payable, whether at the due date thereof or at a date fixed for prepayment thereof or otherwise; provided that, if any such failure shall result from the malfunctioning or shutdown of any wire transfer or other payment system reasonably employed by the Borrower to make such payment or from an inadvertent error of a technical or clerical nature by the Borrower or any bank or other entity reasonably employed by the Borrower to make such payment, no Event of Default shall result under this paragraph (a) during the period (not in excess of two Business Days) required by the Borrower to make alternate payment arrangements;

(b) the Borrower shall fail to pay any interest on any Loan or any fee or any other amount (other than an amount referred to in clause (a) of this Article) payable under this Agreement, when and as the same shall become due and payable, and such failure shall continue unremedied for a period of ten days;

(c) any representation or warranty made or deemed made by or on behalf of the Borrower or any Subsidiary in or in connection with this Agreement or any

amendment or modification hereof, or in any report, certificate, financial statement or other document furnished pursuant to or in connection with this Agreement or any amendment or modification hereof, shall prove to have been incorrect in any material respect when made or deemed made;

(d) the Borrower shall fail to observe or perform any covenant, condition or agreement contained in this Agreement (other than those specified in clause (a), (b) or (c) of this Article), and such failure shall continue unremedied for a period of 30 days after notice thereof from the Administrative Agent (given at the request of any Lender) to the Borrower;

(e) any event of default or similar event or condition occurs (and continues after any applicable grace period) under any mortgage, indenture or instrument under which there may be issued, or by which there may be secured or evidenced, any Material Indebtedness, whether such Material Indebtedness now exists or shall hereafter be created and shall result in any Material Indebtedness becoming due prior to its scheduled maturity (other than any such event or condition arising solely out of the violation by the Borrower or any Subsidiary of any covenant in any way restricting the Borrower’s, or any such Subsidiary’s, right or ability to sell, pledge or otherwise dispose of Unrestricted Margin Stock) and such acceleration shall not be rescinded or annulled in accordance with the terms of such mortgage, indenture or investment, as the same case may be; provided that (i) this clause (e) shall not apply to secured Indebtedness that becomes due as a result of the voluntary permitted sale or transfer of the property or assets securing such Indebtedness and (ii) any acceleration of Indebtedness of any CSX/NS Entity (other than a CSX Conrail Subsidiary) shall not be included for purposes of determining if an Event of Default has occurred under this paragraph so long as such acceleration (x) does not result from a breach by the Borrower of its obligations under the CSX/NS Agreement (or the definitive documentation referred to therein) or (y) would not result in a Material Adverse Effect;

(f) an involuntary proceeding shall be commenced or an involuntary petition shall be filed seeking (i) liquidation, reorganization or other relief in respect of the Borrower or any Significant Subsidiary or Significant CSX/NS Entity or its debts, or of a substantial part of its assets, under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect or (ii) the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or any Significant Subsidiary or Significant CSX/NS Entity or for a substantial part of its assets, and, in any such case, such proceeding or petition shall continue undismissed for 60 days or an order or decree approving or ordering any of the foregoing shall be entered;

(g) the Borrower or any Significant Subsidiary or Significant CSX/NS Entity shall (i) voluntarily commence any proceeding or file any petition seeking liquidation, reorganization or other relief under any Federal, state or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect, (ii) consent to the institution of, or fail to contest in a timely and appropriate manner, any proceeding or petition described in clause (f) of this Article, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or any Significant Subsidiary or Significant CSX/NS Entity or for a substantial part of its assets,

(iv) file an answer admitting the material allegations of a petition filed against it in any such proceeding, (v) make a general assignment for the benefit of creditors or (vi) take any action for the purpose of effecting any of the foregoing;

(h) the Borrower or any Significant Subsidiary or Significant CSX/NS Entity shall become unable, admit in writing or fail generally to pay its debts as they become due;

(j) an ERISA Event shall have occurred that, in the reasonable opinion of the Majority Lenders, when taken together with all other ERISA Events that have occurred, would result in a Material Adverse Effect; or

(k) a Change in Control shall occur and on the date which is four months after the occurrence of such Change in Control the Applicable Rate shall be determined by reference to Category 6;

then, and in every such event (other than an event with respect to the Borrower described in clause (f) or (g) of this Article as a result of which the Administrative Agent and the Lenders shall not be permitted, without special relief, to exercise their rights or remedies under clause (i) or (ii) below), and at any time thereafter during the continuance of such event, the Administrative Agent (with the consent of the Majority Lenders) may, and at the request of the Majority Lenders shall, by notice to the Borrower, take either or both of the following actions, at the same or different times: (i) terminate the Commitments, and thereupon the Commitments shall terminate immediately, and (ii) declare the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower; and in case of any event with respect to the Borrower described in clause (f) or (g) of this Article described above, the Commitments shall automatically terminate and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

ARTICLE VIII

The Agents

Each of the Lenders hereby irrevocably appoints JPMorgan Chase Bank as its agent and authorizes JPMorgan Chase Bank to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto. Each Lender acknowledges that Citibank N.A. and The Bank of Nova Scotia shall be Co-Syndication Agents with respect to this Agreement and that Credit Suisse First Boston and Mizuho Corporate Bank, Ltd. shall be Co-Documentation Agents with respect to this Agreement. The Co-Syndication Agents and Co-Documentation Agents shall have no duties in such capacities in addition to any duties in their capacity as Lenders.

Each bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

No Agent shall have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) no Agent shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) no Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing by the Lenders entitled to so require, and (c) except as expressly set forth herein, no Agent shall have any duty to disclose, nor shall such Agent be liable for the failure to disclose, any information relating to the Borrower or any of the Subsidiaries that is communicated to or obtained by such Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Lenders entitled to so require or in the absence of its own gross negligence or willful misconduct. No Agent shall be deemed to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and no Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made to any Lender in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance by the Borrower of any of the covenants, agreements or other terms or, except as provided in clause (v) below, conditions set forth herein, (iv) with respect to parties other than such Agent, the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Each Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it in good faith to be genuine and to have been signed or sent by the proper

Person. Each Agent also may rely upon any statement made to it orally or by telephone and believed by it in good faith to be made by the proper Person, and shall not incur any liability for relying thereon. Each Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in good faith in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent and for which it is responsible. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent reasonably selected by the Administrative Agent and to the Related Parties of the Agents and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, with the consent of the Borrower (which consent shall not be required if at the time of such appointment any Default or Event of Default shall have occurred and be continuing), to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a commercial bank with an office in New York, New York and having a combined capital and surplus of at least $1,000,000,000. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender represents that it has not relied upon the Unrestricted Margin Stock in its credit analysis or its decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

SECTION 9.02. Waivers; Amendments. (a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a

waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.08(d) or change 2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, in either case without the written consent of each Lender, or (v) change any of the provisions of this Section or the definition of “Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent.

SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the reasonable fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement or any Note, including its rights under this Section, or in connection with the Loans made hereunder, including in connection with any workout, restructuring or negotiations in respect thereof.

(b) The Borrower shall indemnify the Administrative Agent and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or the use of the proceeds therefrom, or (iii) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses resulted

from the gross negligence or willful misconduct of such Indemnitee. The foregoing indemnification shall not cover any such claims, damages, losses, liabilities or expenses relating to (i) any Taxes or (ii) any costs or capital requirements (whenever imposed) to any Lender or any corporation controlling such Lender as a result of such Lender’s Commitment or its Loans, but in each case without prejudice to Sections 2.14, 2.15, 2.16 and 9.03.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after written demand therefor, accompanied by such documentation as the Borrower may reasonably request to evidence the basis for, and calculation of, such amount.

SECTION 9.04. 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 permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may, at no additional cost to the Borrower, assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) except in the case of an assignment to a Lender or (to the extent the obligations of such Lender Affiliate are guaranteed by or otherwise remain the obligations of the relevant Lender) a Lender Affiliate, the Borrower must give its prior written consent to such assignment (which consent shall not be unreasonably withheld), (ii) except in the case of an assignment to a Lender, the Administrative Agent must give its prior written consent to such assignment (which consent shall not be unreasonably withheld), (iii) except in the case of an assignment to a Lender or a Lender Affiliate or an assignment of the entire remaining amount of the assigning Lender’s Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment and the amount of its Commitment remaining thereafter (determined in each case as of the date the Assignment and Acceptance with respect to such assignment is delivered to the

Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, (iv) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement (including its Revolving Loans), except that this clause (iv) shall not apply to rights in respect of outstanding Competitive Loans, (v) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and (vi) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default under clause (a), (b), (f) or (g) of Article VII has occurred and is continuing. Upon acceptance and recording pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party hereto and, to the extent of (but not greater than) the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14, 2.15, 2.16 and 9.03 and be subject to Section 9.12). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section.

(c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be prima facie evidence thereof absent manifest error, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection during normal business hours by the Borrower at any reasonable time and from time to time upon reasonable advance notice.

(d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(e) Any Lender may, without the consent of, and at no additional cost to, the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement

(including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.14, 2.15 and 2.16 to the same (but no greater) extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.14, 2.15 or 2.16 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any such pledge or assignment to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may, at no additional cost to the Borrower, grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof in the same manner and to the same extent as if such option had not been granted. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender, (1) the Granting Lender shall have the sole right and responsibility to deliver all consents and waivers required or requested, and to perform all obligations required, under this Agreement with respect to its SPC, and (2) no SPC shall be entitled to receive any greater amounts pursuant to any provision of this Agreement than the Granting Lender would have been entitled to receive in respect of any Loan made by such SPC. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization,

arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof; provided, that no such restriction shall apply with respect to the Granting Lender. In addition, notwithstanding anything to the contrary contained in this Section 9.04, any SPC may, at no additional cost to the Borrower, (x) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loan such SPC has made hereunder to its Granting Lender or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of any such Loan and (y) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This subsection 9.04(h) may not be amended without the written consent of any SPC with Loans outstanding hereunder.

SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that any Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 2.14, 2.15, 2.16, 9.03 and 9.12 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender 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 indebtedness at any time owing by such Lender 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 setoff) which such Lender may have.

SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment resulting therefrom, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State court or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final and non-appealable judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction.

(c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER

AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.12. Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (i) to its and its Affiliates’ directors, officers, employees, representatives and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (ii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, or requested by any regulatory authority, but only, except with respect to bank examiners, after the Administrative Agent or the relevant Lender provides such written notice to the Borrower of such proposed disclosure as is reasonable under the circumstances and permitted by law, (iii) to any other party to this Agreement, (iv) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or any Note or the enforcement of rights hereunder or thereunder, (v) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (vi) subject to an agreement containing provisions substantially the same as those of this Section, to any direct or indirect counterparty to any Swap Agreement (or any professional advisor to such counterparty), (vii) with the consent of the Borrower or (viii) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section, (y) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Borrower (other than a source known to be disclosing such Information in violation of a confidentiality agreement with the Borrower) or (z) was available to the Administrative Agent or the relevant Lender prior to such Person becoming a Lender. For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 9.13. USA PATRIOT Act. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (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.
