For purposes of the foregoing, (i) if neither Moody's 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 Moody's 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 Moody's 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 Moody's and S&P for the Index
Debt shall be changed (other than as a result of a change in the rating system
of Moody's 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 Moody's 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 Moody's 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.

         "Assignment and Acceptance" means an assignment and acceptance entered
into by a Lender and an assignee (with the consent of any party whose consent is
required by

Section 9.04), and accepted by the Administrative Agent, in the form of Exhibit
A or any other form approved by the Administrative Agent and the Borrower.

         "Attributable Debt" means, at any date with respect to any
Sale/Leaseback Transaction in respect of which the obligations of the Borrower,
any Subsidiary or any CSX Conrail Subsidiary do not constitute Capital Lease
Obligations, the aggregate amount of rental payments due from the Borrower, such
Subsidiary or such CSX Conrail Subsidiary, as the case may be, under the lease
entered into in connection with such Sale/Leaseback Transaction during the
remaining term of such lease, net of rental payments which have been defeased or
secured by deposits, discounted from the respective due dates thereof to such
date using a discount rate equal to the discount rate that would then be used to
calculate the amount of Capital Lease Obligations with respect to a comparable
capital lease.

         "Availability Period" means the period from and including the Closing
Date to but excluding the earlier of the Maturity Date and the date of
termination of the Commitments.

         "Board" means the Board of Governors of the Federal Reserve System of

single Interest Period is in effect.

promptly as practicable. Each Competitive Bid shall specify (i) the principal
amount (which shall be a minimum of $5,000,000 and an integral multiple of
$1,000,000 and which may equal the entire principal amount of the Competitive
Borrowing requested by the Borrower) of the Competitive Loan or Loans that 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

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

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

Lender by telecopy whether or not its Competitive Bid has been accepted (and, if

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

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

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

                                                                              22

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

<PAGE>

                                                                              23

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 shall be
automatically reduced in an 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) 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.

<PAGE>

                                                                              24

         (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

<PAGE>

                                                                              25

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

<PAGE>

                                                                              26

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.

         (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.

         (c)   Each Fixed Rate Loan shall bear interest at a rate per annum
equal to the Fixed Rate 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

<PAGE>

                                                                              27

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;

<PAGE>

                                                                              28

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

<PAGE>

                                                                              29

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

<PAGE>

                                                                              30

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 270 Park Avenue, New
York, New York, 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

<PAGE>

                                                                              31

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

<PAGE>

                                                                              32

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 III

                         Representations and Warranties

        The Borrower represents and warrants to the Lenders that:

        SECTION 3.01. Organization; Powers. Each of the Borrower and the
Significant Subsidiaries is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, has all
requisite power and authority to carry on its business as now conducted and,
except where the failure to do so, individually or in the aggregate, would not
result in a Material Adverse Effect, is qualified to do business in, and is in
good standing in, every jurisdiction where such qualification is required.

        SECTION 3.02. Authorization; Enforceability. The Transactions are within
the Borrower's corporate powers and have been duly authorized by all necessary
corporate action of the Borrower. This Agreement has been duly executed and

<PAGE>

                                                                              33

valid and binding obligation of the Borrower, enforceable in accordance with its
terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium
or other laws affecting creditors' rights generally and subject to general
principles of equity, regardless of whether considered in a proceeding in equity
or at law.

        SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions (a)
do not require any consent or approval of, registration or filing with, or any
other action by, any Governmental Authority, except such as have been obtained
or made and are in full force and effect, (b) will not violate any applicable
law or regulation or the charter, by-laws or other organizational documents of
the Borrower, any Subsidiary or any CSX/NS Entity or any order of any
Governmental Authority, (c) will not violate or result in a default, or give
rise to a right to require any material payment, under any indenture, agreement
or other instrument binding upon the Borrower, any Subsidiary or any of their
respective assets (or, in the case of CSX/NS Acquisition Sub or Conrail or any
of its subsidiaries (excluding any NS Conrail Subsidiaries), any indenture,
agreement or other instrument a violation, default or required payment under
which would result in a Material Adverse Effect), and (d) will not result in the
creation or imposition of any Lien on any material asset of the Borrower or any
Subsidiary (or, in the case of CSX/NS Acquisition Sub or Conrail or any of its
subsidiaries (excluding any NS Conrail Subsidiaries), any Lien on any of its
assets if such Lien would result in a Material Adverse Effect).

        SECTION 3.04. Financial Condition; No Material Adverse Change. (a) The
Borrower has heretofore furnished to the Lenders its consolidated statement of
financial position, and statements of earnings, changes in shareholders' equity
and cash flows (i) as of and for the fiscal year ended December 28, 2001,
reported on by Ernst & Young LLP, independent public accountants, and (ii)
except for statements of changes in shareholders' equity, as of and for the
fiscal quarter ended March 29, 2002, certified by a Financial Officer. Such
financial statements present fairly, in all material respects, the financial
position and results of operations and cash flows of the Borrower and its
consolidated Subsidiaries as of such dates and for such periods in accordance
with GAAP, subject to year-end audit adjustments and the absence of footnotes in
the case of the statements referred to in clause (ii) above.

        (b) Since December 28, 2001, there has been no Material Adverse Effect.

        SECTION 3.05. Properties. (a) Each of the Borrower and the Subsidiaries
has good title to, or valid leasehold interests in or rights to use, all its
real and personal property material to its business, except for such
irregularities that, individually or in the aggregate, would not result in a
Material Adverse Effect.

        (b) Each of the Borrower and the Subsidiaries owns, or is licensed to
use, all trademarks, tradenames, copyrights, patents and other intellectual
property material to its business, and the use thereof by the Borrower and the
Subsidiaries does not infringe upon the rights of any other Person, except for
any such infringements that, individually or in the aggregate, would not result
in a Material Adverse Effect.

        SECTION 3.06. Litigation and Environmental Matters. (a) There is no
pending litigation or administrative proceeding or other legal or regulatory
development that is reasonably likely to result in a Material Adverse Effect or
to materially adversely affect the rights and remedies of the Lenders hereunder.

                                                                              34

        (b) Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, would not result in a
Material Adverse Effect, neither the Borrower nor any Subsidiary nor any CSX/NS
Entity (i) has failed to comply with any Environmental Law or to obtain,
maintain or comply with any permit, license or other approval required under any
Environmental Law, (ii) has become subject to any Environmental Liability, (iii)
has received notice of any claim with respect to any Environmental Liability or
(iv) knows of any basis for any Environmental Liability.

        SECTION 3.07. Compliance with Laws and Agreements. Each of the Borrower,
the Subsidiaries and the CSX/NS Entities is in compliance with all laws,
regulations and orders (other than Environmental Laws) of any Governmental
Authority applicable to it or its property (including Regulation U) and all
indentures, agreements and other instruments binding upon it or its property,
except where the failure to do so, individually or in the aggregate, would not
result in a Material Adverse Effect. No Default has occurred and is continuing.

        SECTION 3.08. Investment and Holding Company Status. Neither the
Borrower nor any Subsidiary is (a) an "investment company" as defined in, or
subject to regulation under, the Investment Company Act of 1940 or (b) a
"holding company" as defined in, or subject to regulation under, the Public
Utility Holding Company Act of 1935.

        SECTION 3.09. Taxes. Each of the Borrower, the Subsidiaries and the
CSX/NS Entities has timely filed or caused to be filed all Tax returns and
reports required to have been filed and has paid or caused to be paid all Taxes
required to have been paid by it, except (a) Taxes that are being contested in
good faith by appropriate proceedings and for which the Borrower, such
Subsidiary or such CSX/NS Entity, as applicable, has set aside on its books
adequate reserves or (b) to the extent that the failure to do so would not
result in a Material Adverse Effect.

        SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, would result in a Material
Adverse Effect.

        SECTION 3.11. Disclosure. None of the reports, financial statements,
certificates or other information furnished by or on behalf of the Borrower to
the Administrative Agent or any Lender in connection with the negotiation of
this Agreement or delivered hereunder (as modified or supplemented by other
information so furnished) contains any material misstatement of fact or omits to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; provided that,
with respect to projected or pro forma financial information, the Borrower
represents only that such information was prepared in good faith based upon
assumptions believed to be reasonable at the time, it being understood that such
pro forma statements or projections are inherently subjective and are subject to
significant uncertainties and contingencies many of which are beyond the control
of the Borrower and that no assurance can be given that such projections or pro
forma financial statements will be realized.

     counsel to deliver such opinions.

          (c) The Administrative Agent shall have received (i) a certificate of
     the Borrower, dated the Closing Date, as to the incumbency and signature of
     the officers of the Borrower executing this Agreement and authorized to

     Administrative Agent and (ii) true and complete copies of the certificate
     of incorporation and by-laws of the Borrower, certified as of the Closing

          (e) The Borrower shall have paid all fees required to be paid, and all
     expenses required to be paid and for which invoices have been presented, on

     Borrower shall (and does hereby) terminate the commitments under the
     Existing Credit Agreement and (ii) all principal, interest and fees under

     by the Lenders (to the extent such Lenders are parties to the Existing
     Credit Agreement).

The Administrative Agent shall notify the Borrower and the Lenders of the
Closing Date, and such notice shall be conclusive and binding.

          SECTION 4.02. Each Credit Event. The obligation of each Lender to make
a Loan on the occasion of any Borrowing is subject to the satisfaction of the

          (a) The representations and warranties of the Borrower set forth in
     this Agreement (other than the representations and warranties set forth in

     of such Borrowing.

          (b) At the time of and immediately after giving effect to such
     Borrowing, no Default shall have occurred and be continuing.

Each Borrowing shall be deemed to constitute a representation and warranty by
the Borrower on the date thereof as to the matters specified in paragraphs (a)
and (b) of this Section.

                                   ARTICLE V

                              Affirmative Covenants

          Until the Commitments shall have expired or been terminated and the
principal of and interest on each Loan and all fees payable hereunder shall have
been paid in full, the Borrower covenants and agrees with the Lenders that:

          SECTION 5.01. Financial Statements and Other Information. The Borrower
will furnish to each Lender through the Administrative Agent:

          (a) as soon as available but in any event within 120 days after the
     end of each fiscal year of the Borrower, its audited consolidated statement
     of financial position and related statements of earnings, changes in
     shareholders' equity and cash flows as of the end of and for such year,
     setting forth in each case in comparative form the figures for the previous
     fiscal year, all reported on by Ernst & Young LLP or other independent
     public accountants of recognized national standing (without a "going
     concern" or like qualification or exception and without any qualification
     or exception as to the scope of such audit) to the effect that such
     consolidated financial statements present fairly in all material respects
     the financial position, results of operations and cash flows of the
     Borrower and its consolidated Subsidiaries on a consolidated basis in
     accordance with GAAP; provided, however, that the Borrower may deliver, in
     lieu of the foregoing, the annual report of the Borrower for such fiscal
     year on Form 10-K filed with the SEC, but only so long as the financial
     statements contained in such annual report on Form 10-K are substantially
     the same in content as the financial statements referred to in the
     preceding provisions of this paragraph (a);

          (b) as soon as available but in any event within 60 days after the end
     of each of the first three fiscal quarters of each fiscal year of the
     Borrower, its consolidated statement of financial position and related
     statements of earnings and cash flows as of the end of and for such fiscal
     quarter and the then elapsed portion of the fiscal year, setting forth in
     each case in comparative form the figures for the corresponding period or
     periods of (or, in the case of the balance sheet, as of the end of) the
     previous fiscal year, all certified by one of its Financial Officers as
     presenting fairly in all material respects the financial position, results
     of operations and cash flows of the Borrower and its

                                                                              37

     consolidated Subsidiaries on a consolidated basis in accordance with GAAP,
     subject to normal year-end audit adjustments and the absence of footnotes;
     provided, however, that the Borrower may deliver, in lieu of the foregoing,
     the quarterly report of the Borrower for such fiscal quarter on Form 10-Q
     filed with the SEC, but only so long as the financial statements contained
     in such quarterly report on Form 10-Q are substantially the same in content
     as the financial statements referred to in the preceding provisions of this
     paragraph (b);

          (c) concurrently with each delivery of financial statements under
     clause (a) or (b) above, a certificate of a Financial Officer of the
     Borrower (i) certifying as to whether, to the best knowledge of such
     Financial Officer, a Default has occurred and is continuing and, if a
     Default has occurred and is continuing, specifying the details thereof and
     any action taken or proposed to be taken with respect thereto, (ii) setting
     forth reasonably detailed calculations demonstrating compliance with
     Section 6.05 and (iii) stating whether any change in GAAP or in the
     application thereof has occurred since the date of the audited financial
     statements referred to in Section 3.04 and, if any such change has
     occurred, specifying the effect of such change on the financial statements
     accompanying such certificate;

          (d) concurrently with each delivery of financial statements under
     clause (a) above, a letter signed by the accounting firm that reported on
     such financial statements to the effect that, in the course of the
     examination upon which their report for such fiscal year was based (but
     without any special or additional audit procedures for that purpose other
     than review of the terms and provisions of this Agreement), nothing came to
     their attention that caused them to believe that there were any Defaults or
     Events of Default involving accounting matters or, if such accountants
     became aware of any such Defaults or Events of Default, specifying the
     nature thereof;

          (e) promptly after the same become publicly available, copies of all
     periodic and other reports on Forms 8-K, 10-Q and 10-K and all proxy
     statements filed by the Borrower or any Subsidiary with the SEC or any
     other documents distributed by the Borrower to its shareholders generally
     which contain the equivalent information to that contained in such Forms or
     proxy statements;

          (f) upon any sale or other disposition of Shares by the Borrower or
     any Subsidiary, a certificate of a Financial Officer setting forth in
     reasonable detail the calculations required to determine the portion of
     such Shares which constitute Restricted Margin Stock, the portion of such
     Shares which constitute Unrestricted Margin Stock and the Net Cash Proceeds
     attributable to each such portion; and

          (g) promptly following any request therefor, such other information
     regarding the operations and financial condition of the Borrower or any
     Subsidiary, or compliance with the terms of this Agreement, as the
     Administrative Agent or any Lender may reasonably request.

          SECTION 5.02. Notices of Material Events. The Borrower will furnish to
each Lender through the Administrative Agent prompt written notice of the
following:

                                                                              38

     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

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

                                                                              46

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.

          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

<PAGE>

                                                                              47

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

<PAGE>

                                                                              48

taking or not taking action under or based upon this Agreement, any related
agreement or any document furnished hereunder or thereunder.

                                   ARTICLE IX

                                  Miscellaneous

          SECTION 9.01. Notices. Except in the case of notices and other
communications expressly permitted to be given by telephone, all notices and
other communications provided for herein shall be in writing and shall be
delivered by hand or overnight courier service, mailed by certified or
registered mail or sent by telecopy, as follows:

          (a) if to the Borrower, to it at CSX Corporation, BellSouth Tower,
     21/st/ Floor - J220, Jacksonville, FL 32202, Attention of Treasurer
     (Telecopy No. (904) 633-1139);

          (b) if to the Administrative Agent, to JPMorgan Chase Bank, Agent Bank
     Services, One Chase Manhattan Plaza, 8th Floor, New York, New York 10081,
     Attention of Jesus C. Sang (Telecopy No. (212) 552-5650), with a copy to
     JPMorgan Chase Bank, 270 Park Avenue, New York, New York 10017, Attention
     of Julie Long (Telecopy No. (212) 270-5127); and

          (c) if to any Lender, to it at its address (or telecopy number) set
     forth in its Administrative Questionnaire.

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

          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

<PAGE>

                                                                              49

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 2.10(c) 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

<PAGE>

                                                                              50

(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 a Lender Affiliate, each of the Borrower and the Administrative Agent
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
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, (iii) 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 (iii) shall not apply to rights in respect of
outstanding Competitive Loans, (iv) 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 (v) 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 (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

<PAGE>

                                                                              51

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.

<PAGE>

                                                                              52

          (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.

          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

<PAGE>

                                                                              53

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

defined below), except that Information may be disclosed (a) 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), (b) 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

Borrower of such proposed disclosure as is reasonable under the circumstances
and permitted by law, (c) to any other party to this Agreement, (d) in
connection with the exercise of any remedies hereunder or any suit, action or

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.
