          SECTION 2.  AMOUNTS AND TERMS OF CREDIT FACILITY.
                      ------------------------------------

          2.1  The Commitment.  (a)  Subject to and upon the terms and

NEG, Inc. and (B) the Date Certain.

               -------------------
notice of the Eurodollar Loan to be incurred hereunder, provided that any such
                                                        --------
notice shall be deemed to have been given on a certain day only if given before
1:00 P.M. (New York time) on such day.  Such notice (the "Notice of Borrowing")
                                                          -------------------

               ---------------------
on the Closing Date, each Lender will make available such Lender's pro rata
                                                                   --- ----
share of the amount of Borrowing requested to be made on such date.  All such
amounts will be made available in Dollars and in immediately available funds and

"Note").
 ----

          (b) The Note issued to a Lender shall (i) be executed by the Borrower,
(ii) be payable to such Lender or its Assignee and be dated the Closing Date
(or, if issued after the Closing Date, be dated the date of issuance thereof),
(iii) be in a stated principal amount equal to the Loan made by, or assigned to,
such Lender, as the case may be, and be payable in the outstanding principal
amount of the Loan evidenced thereby, (iv) mature on the earlier of (A) the date
of a Spin-Off of NEG, Inc. and (B) the Date Certain, (v) bear interest as

Loan made by it and each payment in respect thereof and will prior to any
transfer of its Note endorse on the reverse side thereof the outstanding
principal amount of the Loan evidenced thereby.  Failure to make any such
notation or any error in such notation shall not affect the Borrower's
obligations in respect of such Loan.

          2.5  Interest.  (a)  The Borrower agrees to pay interest in respect of
               --------
the unpaid principal amount of any Base Rate Loan from the date of conversion
thereof pursuant to Section

<PAGE>

2.7(b) until the maturity thereof (whether by acceleration or otherwise) at a
rate per annum which shall be equal to the sum of the Applicable Margin plus the
Base Rate each as in effect from time to time.

          (b) The Borrower agrees to pay interest in respect of the unpaid
principal amount of each Eurodollar Loan from the date of Borrowing thereof
until the earlier of (i) the maturity thereof (whether by acceleration or
otherwise) and (ii) the conversion of such Eurodollar Loan to a Base Rate Loan
pursuant to Section 2.7(b) at a rate per annum which shall, during each Interest
Period applicable thereto, be equal to the sum of the Applicable Margin as in
effect from time to time during such Interest Period plus the Eurodollar Rate
for such Interest Period.

          (c) Overdue principal and, to the extent permitted by law, overdue
interest in respect of each Loan and any other overdue amount payable by the
Borrower shall, in each case, bear interest at a rate per annum equal to the

          (d) Accrued (and theretofore unpaid) interest shall be payable (i) in
respect of each Base Rate Loan, (x) quarterly in arrears on each Quarterly Date,
(y) on the date of any repayment or prepayment in full of the outstanding
principal amount of such Base Rate Loan, and (z) at maturity (whether by
acceleration or otherwise) and, after such maturity, on demand, and (ii) in
respect of each Eurodollar Loan, (x) on the last day of each Interest Period
applicable thereto and, in the case of an Interest Period in excess of three
months, on each date occurring at three month intervals after the first day of
such Interest Period, and (y) on the date of any repayment or prepayment (on the
amount repaid or prepaid), at maturity (whether by acceleration or otherwise)
and, after such maturity, on demand; provided that the first interest payment
                                     --------
shall be due and payable in advance on the Closing Date in an amount equal to
the Interest Prepaid Amount and the first Interest Period shall be a one year
period (the "First Interest Period").

          (e) Upon each Interest Determination Date with respect to any
Eurodollar Loan, the Administrative Agent shall determine the Eurodollar Rate
for the relevant Interest Period applicable to such Eurodollar Loan and shall
promptly notify the Borrower thereof.  Each such determination shall, absent
manifest error, be final and conclusive and binding on all parties hereto.

          2.6  Interest Periods.  (a)  At the time the Borrower gives the Notice
               ----------------
of Borrowing or prior to 1:00 P.M. (New York time) on the third Business Day
prior to the expiration of an Interest Period applicable to a Eurodollar Loan
(in the case of any subsequent Interest Period), the Borrower shall have the
right to elect the interest period (each an "Interest Period") applicable to
                                             ---------------
such Eurodollar Loan, which Interest Period shall, at the option of the
Borrower, be a one, two, three or six-month period; provided that (in each
                                                    --------
case):

          (i)  the initial Interest Period for any Eurodollar Loan shall
     commence on the date of Borrowing of such Eurodollar Loan and each Interest
     Period occurring thereafter in respect of such Eurodollar Loan shall
     commence on the day on which the next preceding Interest Period applicable
     thereto expires;

                                      -3-
<PAGE>

           (ii)  if any Interest Period for a Eurodollar Loan begins on a day
     for which there is no numerically corresponding day in the calendar month
     at the end of such Interest Period, such Interest Period shall end on the
     last Business Day of such calendar month;

           (iii) if any Interest Period for a Eurodollar Loan would otherwise
     expire on a day which is not a Business Day, such Interest Period shall
     expire on the next succeeding Business Day; provided, however, that if any
                                                 --------  -------
     Interest Period for such Eurodollar Loan would otherwise expire on a day
     which is not a Business Day but is a day of the month after which no
     further Business Day occurs in such month, such Interest Period shall
     expire on the next preceding Business Day;

           (iv)  no Interest Period may be selected at any time when a Default
     or an Event of Default is then in existence; and

           (v)   no Interest Period in respect of any Borrowing of any
     Eurodollar Loan shall be selected which extends beyond the Date Certain.

          If upon the expiration of any Interest Period applicable to any
Eurodollar Loan, the Borrower has failed to elect, or is not permitted to elect,
a new Interest Period to be applicable to such Eurodollar Loan as provided
above, the Borrower shall be deemed to have elected a one-month Interest Period
effective as of the expiration date of such current Interest Period.

          (b) During the First Interest Period, the Borrower shall have the
right, at the times indicated and following the procedure set forth in Section
2.6(a), to deliver notice to the Administrative Agent to indicate Interest
Periods of one, two, three or six months (each such Interest Period, with
respect to any Eurodollar Loan, a "Selected Interest Period") for purposes of
                                   ------------------------
comparing the interest rates.  The Administrative Agent shall determine the
Eurodollar Rate for each such Selected Interest Period applicable to a
Eurodollar Loan and the amount of accrued interest (such amount, the "Selected
                                                                      --------
Interest Amount") which would be payable in respect of such Eurodollar Loan for
---------------
each such Selected Interest Period, which determination shall, absent manifest
error, be final, conclusive and binding on all parties hereto.  On the date
which is the earlier of the date of prepayment of all the Loans by the Borrower
pursuant to the terms hereof and the first anniversary of the Closing Date (x)
the Borrower shall pay to the Administrative Agent the amount by which the sum
of the aggregate Selected Interest Amounts (discounted to present value as of
the Closing Date using a discount factor of 4.25%) plus any amounts due and
payable under Section 2.8 with respect to a Selected Interest Period exceeds the
Interest Prepaid Amount or (y) each Lender shall credit to the Borrower the
amount by which the Interest Prepaid Amount with respect to the Loan of such
Lender exceeds the sum of the aggregate Selected Interest Amounts (discounted to
present value as of the Closing Date using a discount factor of 4.25%) with
respect to the Loan of such Lender plus any amounts due and payable to such
Lender under Section 2.8 or otherwise under this Agreement.  In no event shall a
Selected Interest Period extend beyond the last day of the First Interest
Period.

          2.7  Increased Costs, Illegality, etc.  (a)  In the event that a
               ---------------------------------
Lender shall have determined (which determination shall, absent manifest error,
be final and conclusive and binding upon all parties hereto):

                                      -4-
<PAGE>

           (i)   on any Interest Determination Date that, by reason of any
     changes arising after the date of this Agreement affecting the interbank
     Eurodollar market, adequate and fair means do not exist for ascertaining
     the applicable interest rate on the basis provided for in the definition of
     Eurodollar Rate; or

           (ii)  at any time, that such Lender shall incur increased costs or
     reductions in the amounts received or receivable hereunder with respect to
     any Eurodollar Loan of such Lender because of (x) any change since the
     Closing Date in any applicable law or governmental rule, regulation, order,
     guideline or request (whether or not having the force of law) or in the
     interpretation or administration thereof and including the introduction of
     any new law or governmental rule, regulation, order, guideline or request,
     such as, for example, but not limited to:  (A) a change in the basis of
     taxation of payment to such Lender of the principal of or interest on such
     Lender's Loan or Note or any other amounts payable to such Lender hereunder
     (except for changes in the rate of tax on, or determined by reference to,
     the net income or net profits of such Lender pursuant to the laws of the
     jurisdiction in which it is doing business, organized or in which its
     principal office or applicable lending office is located or any subdivision
     thereof or therein) or (B) a change in official reserve requirements, but,
     in all events, excluding reserves required under Regulation D to the extent
     included in the computation of the Eurodollar Rate and/or (y) other
     circumstances (other than with respect to taxes) arising since the Closing
     Date affecting such Lender (or its Source), the interbank Eurodollar market
     or the position of such Lender in such market; or

           (iii) at any time, that the making or continuance of any Eurodollar
     Loan has been made (x) unlawful by any law or governmental rule, regulation
     or order, (y) impossible by compliance by such Lender in good faith with
     any governmental request (whether or not having force of law) or (z)
     impracticable as a result of a contingency occurring after the Closing Date
     which materially and adversely affects the interbank Eurodollar market;

then, and in any such event, such Lender shall promptly give notice (by
telephone promptly confirmed in writing) to the Borrower of such determination.
Thereafter (x) in the case of clause (i) above, Eurodollar Loans shall no longer
be available until such time as such Lender notifies the Borrower that the
circumstances giving rise to such notice by the Lender no longer exist, (y) in
the case of clause (ii) above, the Borrower agrees to pay to such Lender, upon
such Lender's written request therefor, such additional amounts (in the form of
an increased rate of, or a different method of calculating, interest or
otherwise as such Lender in its sole discretion shall determine) as shall be
required to compensate such Lender for such increased costs or reductions in
amounts received or receivable hereunder (a written notice as to the additional
amounts owed to such Lender, showing in reasonable detail the basis for the
calculation thereof, submitted to the Borrower by such Lender shall, absent
manifest error, be final and conclusive and binding on all the parties hereto)
and (z) in the case of clause (iii) above, the Borrower shall take one of the
actions specified in Section 2.7(b) as promptly as possible and, in any event,
within the time period required by Law.

           Each Lender, at the sole cost and expense of the Borrower (including,
but not limited to, such Lender's internal costs for use of its personnel and
resources), will use its reason-

                                      -5-
<PAGE>

able efforts to minimize taxes indemnifiable by the Borrower under this Section
2.7(a), including by complying with reasonable requests by the Borrower to do or
to refrain from doing any act (including the execution of any certificates or
similar documents required to establish an exemption or relief from any tax), if
such efforts or any such compliance is, in the good faith discretion of such
Lender, of a purely ministerial nature and has no adverse impact on such Lender
or any Affiliate or on the business or operations of the foregoing (unless such
adverse impact is one of a nature and quality such that it is subject to
indemnification and the Borrower has indemnified such Lender against such
adverse impact in a manner satisfactory to such Lender determined in its sole
discretion). The Borrower shall indemnify such Lender for any taxes that may be
imposed on it as a consequence of such compliance.

          (b) At any time that any Eurodollar Loan is affected by the
circumstances described in Section 2.7(a)(i) or (ii), the Borrower may, and in
the case of a Eurodollar Loan affected by the circumstances described in Section
2.7(a)(iii), the Borrower shall, upon at least three Business Days' written
notice to such Lender, require the affected Lender to convert such Eurodollar
Loan into a Base Rate Loan.

          (c) If a Lender determines that after the Closing Date the
introduction of or any change in any applicable law or governmental rule,
regulation, order, guideline, directive or request (whether or not having the
force of law) concerning capital adequacy, or any change in interpretation or
administration thereof by the NAIC or any governmental authority, central bank
or comparable agency, will have the effect of increasing the amount of capital
required or expected to be maintained by such Lender (or its Source) or any
corporation controlling such Lender based on the existence of such Lender's
Commitment hereunder or its obligations hereunder, then the Borrower agrees to
pay to such Lender, upon its written demand therefor, such additional amounts as
shall be required to compensate such Lender or such other corporation for the
increased cost to such Lender or such other corporation or the reduction in the
rate of return to such Lender or such other corporation as a result of such
increase of capital.  In determining such additional amounts, each Lender will
act reasonably and in good faith and will use averaging and attribution methods
which are reasonable, provided that such Lender's determination of compensation
                      --------
owing under this Section 2.7(c) shall, absent manifest error, be final and
conclusive and binding on all the parties hereto.  Such Lender, upon determining
that any additional amounts will be payable pursuant to this Section 2.7(c),
will give prompt written notice thereof to the Borrower, which notice shall show
in reasonable detail the basis for calculation of such additional amounts.

          2.8  Compensation.  The Borrower agrees to compensate each Lender,
               ------------
upon its written request (which request shall set forth in reasonable detail the
basis for requesting such compensation), for all losses, expenses and
liabilities (including, without limitation, any loss, expense or liability
incurred by reason of the liquidation or reemployment of deposits or other funds
required by such Lender to fund its Eurodollar Loan but excluding loss of
anticipated profits) which such Lender may sustain:  (i) if any prepayment or
repayment (including any prepayment or repayment made pursuant to Section 3.1,
Section 3.2 or as a result of an acceleration of the Loans pursuant to Section
8.2) or conversion of any Eurodollar Loan is made on a date other than the last
day of the Interest Period (or during the First Interest Period, any Selected
Interest Period) applicable thereto; or (ii) as a consequence of (x) any other
default by the

Borrower to repay such Eurodollar Loan when required by the terms of this
Agreement or any Note held by such Lender or (y) any election made pursuant to
Section 2.7(b).

          2.9  Extension of Maturity Date   The Borrower may by notice to the
               --------------------------
Administrative Agent and the holders of the Loans not later than thirty (30)
days prior to the Initial Date Certain or the Extended Date Certain occurring
six months after the Initial Date Certain (if the maturity date of the Loans was
extended on the Initial Date Certain to such Extended Date Certain), and upon
payment of the Extension Fees relating to such extension pursuant to the Fee
Letter and the Lehman Fee Letter, extend the maturity date of the Loans to the
earlier of (i) the date of a Spin-Off of NEG, Inc. and (ii) the Extended Date
Certain, but in no event shall the Date Certain be beyond the third anniversary
of the Closing Date; provided, that there shall be no extension of the maturity
                     --------
date of the Loans if on the date of such extension, (a) a Default or an Event of
Default shall be continuing or (b) the aggregate outstanding principal amount of
the Loans at such time shall be more than $692,000,000.

Administrative Agent or any Lender hereunder and under any Note will be made

or other charges being referred to collectively as "Taxes").  If any Taxes are
                                                    -----
so levied or imposed, the Borrower agrees to pay the full amount of such Taxes,
and such additional amounts as may be necessary so that every payment of all

provided for herein or in such Note.  If any amounts are payable in respect of
Taxes pursuant to the preceding sentence, the Borrower agrees to reimburse each
Lender, upon the written request of such Lender, for taxes imposed on or
measured by the net income or net profits of such Lender pursuant to the laws of
the jurisdiction in which such Lender is doing business, organized or in which

behalf of such Lender pursuant to the preceding sentence and in respect of any
amounts paid to or on behalf of such Lender pursuant to this sentence.  The
Borrower will furnish to such Lender within 45 days after the date the payment
of any Taxes is due pursuant to applicable law certified copies of tax receipts
evidencing such payment by such Borrower.  The Borrower agrees to indemnify and
hold harmless each Lender, and reimburse such Lender upon its written request,

the Closing Date or, in the case of a Lender that is an assignee or transferee
of an interest under this Agreement pursuant to Section 9.11(a) (unless such
Assignee was already a Lender hereunder immediately prior to such assignment in
which case such assignee shall reaffirm its ability to deliver the forms set

exemption under an income tax treaty) (or successor forms) certifying to such
Lender's entitlement as of such date to a complete exemption from United States
withholding tax with respect to payments to be made under this Agreement and

Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue
Service Form W-8ECI or

                                      -10-
<PAGE>

Form W-8BEN (with respect to a complete exemption under an income tax treaty)
(or any successor forms) pursuant to clause (i) above, (x) a certificate
substantially in the form of Exhibit C (any such certificate, a "Section
3.4(b)(ii) Certificate") and (y) two accurate and complete original signed
copies of Internal Revenue Service Form W-8BEN (with respect to the portfolio
interest exemption) (or successor form) certifying to such Lender's entitlement
as of such date to a complete exemption from United States withholding tax with
respect to payments of interest to be made under this Agreement and under any
Note. In addition, each such Lender agrees that from time to time after the
Closing Date, when a lapse in time or change in circumstances renders the
previous certification obsolete or inaccurate in any material respect, such
Lender will deliver to the Administrative Agent and the Borrower two new
accurate and complete original signed copies of Internal Revenue Service Form W-
8ECI, Form W-8BEN (with respect to the benefits of any income tax treaty), or
Form W-8BEN (with respect to the portfolio interest exemption) and a Section
3.4(b)(ii) Certificate, as the case may be, and such other forms as may be
required in order to confirm or establish the entitlement of such Lender to a
continued exemption from or reduction in United States withholding tax with
respect to payments under this Agreement and any Note, or such Lender shall
immediately notify the Administrative Agent and the Borrower of its inability to
deliver any such Form or Certificate, in which case such Lender shall not be
required to deliver any such Form or Certificate pursuant to this Section
3.4(b). Notwithstanding anything to the contrary contained in Section 3.4(a) and
the immediately succeeding sentence, (x) the Borrower shall be entitled, to the
extent it is required to do so by law, to deduct or withhold income or similar
taxes imposed by the United States (or any political subdivision or taxing
authority thereof or therein) from interest, fees or other amounts payable
hereunder for the account of any Lender which is not a United States person (as
such term is defined in Section 7701(a)(30) of the Code) for U.S. Federal income
tax purposes to the extent that such Lender has not provided to the
Administrative Agent and the Borrower U.S. Internal Revenue Service Forms that
establish a complete exemption from such deduction or withholding and (y) the
Borrower shall not be obligated pursuant to Section 3.4(a) to gross-up payments
to be made to a Lender in respect of income or similar taxes imposed by the
United States if (I) such Lender has not provided to the Administrative Agent
and the Borrower the Internal Revenue Service Forms required to be provided to
the Administrative Agent and the Borrower pursuant to this Section 3.4(b) or
(II) in the case of a payment, other than interest, to a Lender described in
clause (ii) above, to the extent that such Forms do not establish a complete
exemption from withholding of such taxes. Notwithstanding anything to the
contrary contained in the preceding sentence or elsewhere in this Section 3.4,
the Borrower agrees to pay any additional amounts and to indemnify each Lender
in the manner set forth in Section 3.4(a) (without regard to the identity of the
jurisdiction requiring the deduction or withholding) in respect of any amounts
deducted or withheld by it as described in the immediately preceding sentence as
a result of any changes that are effective after the Closing Date in any
applicable law, treaty, governmental rule, regulation, guideline or order, or in
the interpretation thereof, relating to the deducting or withholding of such
Taxes. The sole consequence of any Lender failing to comply with the requirement
to deliver the Internal Revenue Service Forms or the Section 3.4(b)(ii)
Certificate shall be that the Borrower shall not be obligated pursuant to
Section 3.4(a) to gross-up payments to be made to such Lender in respect of any
resulting U.S. income or similar taxes.

                                      -11-

          (c) Any Lender that is (i) an Assignee pursuant to Section 9.11(a) and
(ii) not a United States person (as such term is defined in Section 7701(a)(30)
of the Code) for U.S. Federal income tax purposes will certify to the Borrower
on or prior to the date of the assignment to such Lender that payments to such
Lender hereunder and under any Note are, as of the date of such assignment, not
subject to any withholding tax imposed by any taxing jurisdiction located
outside of the United States.

          (d) Each Lender, at the sole cost and expense of the Borrower
(including, but not limited to, the Lender's internal costs for use of its
personnel and resources), will use its reasonable efforts to minimize taxes
indemnifiable by the Borrower under this Section 3.4, including by complying
with reasonable requests by the Borrower to do or to refrain from doing any act
(including the execution of any certificates or similar documents required to
establish an exemption or relief from any tax), if such efforts or any such
compliance is, in the good faith discretion of such Lender, of a purely
ministerial nature and has no adverse impact on such Lender or any Affiliate or
on the business or operations of the foregoing (unless such adverse impact is
one of a nature and quality such that it is subject to indemnification and the
Borrower has indemnified such Lender against such adverse impact in a manner
satisfactory to such Lender determined in its sole discretion).  The Borrower
shall indemnify such Lender for any taxes that may be imposed on it as a
consequence of such compliance.  No Lender shall be required to disclose any tax
return or filing or any related information it deems confidential and all
positions taken by each Lender in any tax return, filing or proceeding shall be
within the sole control of such Lender.

          3.5  Allocation.  The parties agree that the Notes issued by the
               ----------
Borrower under this Agreement and the Options issued by LLC under the Option
Agreement, will for federal tax purposes, be treated as an "investment unit" as
such term is defined under Section 1273(c)(2) of the Code and the parties agree
that the consideration paid by each Lender for its Note and Option shall be
allocated as set forth on Schedule 3.5.

          3.6  Fee.  The Borrower shall pay to (a) the Tranche A Lender the
               ---
Commitment Fee payable to it pursuant to the terms of the Fee Letter and (b) the
Tranche B Lender the Commitment Fee payable to it pursuant to the Lehman Fee
Letter.

               --------------------------------

          (a) Subject to the provisions of this Section 3.7, the Administrative
Agent agrees that promptly after its receipt of each payment from or on behalf
of the Borrower in respect of any Obligations of the Borrower hereunder, it
shall promptly distribute such payment to the Lenders pro rata based upon their
                                                      --- ----
respective shares, if any, of the Obligations with respect to which such payment
was received.

          (b) Each of the Lenders agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Financing Documents, or
otherwise), which, in any such case, is in excess of its ratable share of
payments on account of the Obligations obtained by all Lenders, then such Lender
receiving such excess payment shall purchase for cash without recourse or
warranty from the other Lenders an

                                      -12-
<PAGE>

interest in the Obligations of the Borrower to such Lenders in such amount as
shall result in a proportional participation by all the Lenders in such amount;
provided, however, that if all or any portion of such excess amount is
--------  -------
thereafter recovered from such Lender, such purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.

ERISA and Section 4980B of the Code; no lien imposed under the Code or ERISA on
the assets of the Borrower or any Subsidiary of the Borrower or any ERISA

     (ii) Each Foreign Pension Plan has been maintained in substantial
compliance with its terms and with the requirements of any and all applicable
laws, statutes, rules, regulations and orders and has been maintained, where
required, in good standing with applicable regulatory authorities. All

been timely made. Neither the Borrower nor any of its Subsidiaries has incurred
any obligation in connection with the termination of, or withdrawal from, any
Foreign Pension Plan. The present value of the accrued benefit liabilities
(whether or not vested) under each Foreign Pension Plan, determined as of the
end of the Borrower's most recently ended fiscal year on the basis of actuarial
assumptions, each of which is reasonable, did not exceed the current value of
the assets of such Foreign Pension Plan allocable to such benefit liabilities.

          (i)  Without in any way limiting the generality of the other
     provisions contained in this Section 9.2, the Borrower agrees to defend,
     protect, indemnify, save and hold harmless each Indemnified Person, whether
     as beneficiary of any of the Security Documents, as a mortgagee in
     possession, or as successor-in-interest to the Borrower by foreclosure deed
     or deed in lieu of foreclosure, or otherwise, from and against any and all

     quential damages and punitive claims), penalties, fees, claims, actions,
     judgments, suits, costs, disbursements (including, without limitation,
     reasonable legal fees and expenses and consultants' fees and disbursements)
     and expenses (collectively, "Losses") of any kind or nature whatsoever that
                                  ------
     may at any time be incurred by, imposed on, asserted or awarded against any
     such Indemnified Person directly or indirectly based on, or arising out of
     or resulting from, (A) the actual or alleged presence of Hazardous
     Materials on, in, under or affecting all or any portion of any Property of
     the Borrower or any member of the NEG Group whether or not the same
     originates or emanates from any such Property or any property adjoining or
     adjacent to any such Property or from properties at which any Hazardous
     Materials generated, stored or handled by the Borrower were Released or
     disposed of, (B) any Environmental Claim relating to any such Property or
     (C) the exercise of any Secured Party's rights under any of the provisions
     of the Security Documents (the "Indemnified Matters"), whether any of the
                                     -------------------
     Indemnified Matters arise before or after foreclosure of any of the
     security interests or other taking of title to all or any portion of the
     Collateral by the Collateral Agent or any Lender, including, without
     limitation, (x) the costs of removal of any and all Hazardous Materials
     from all or any portion of any such Property or any property adjoining or
     adjacent to any such Property, (y) additional costs required to take
     reasonable precautions to protect against the Release of Hazardous
     Materials on, in, under or affecting any such Property into the air, any
     body of water, any other public domain or any surrounding areas, and (z)
     costs incurred to comply, in connection with all or any portion of any such
     Property or any surrounding areas, with all applicable Environmental Laws
     with respect to Hazardous Materials, except to the extent that any such
     Indemnified Matter arises from the gross negligence or willful misconduct
     of such Indemnified Person.

          (ii) In no event shall any site visit, observation, or testing by any
     Indemnified Person (or any representative of any such Person) be deemed to
     be a representation or warranty that Hazardous Materials are or are not
     present in, on, or under, any Property of the Borrower or any member of the
     NEG Group, or that there has been or shall be compliance with any
     Environmental Law.  Neither the Borrower nor any other Person is entitled
     to rely on any site visit, observation, or testing by any Indemnified
     Person.  No Indemnified Person owes any duty of care to protect the
     Borrower or any other Person against, or to inform the Borrower or any
     other Person of, any Hazardous Materials or any other adverse condition
     affecting any such Property.  No Indemnified Person shall be obligated to
     disclose to the Borrower or any other Person any report or findings made as
     a result of, or in connection with, any site visit, observation, or testing
     by any Indemnified Person.

          (c)  Survival; Defense.  The obligations in this Section 9.2 shall
               -----------------
survive payment of the Loans and all other obligations hereunder.  At the
election of any Indemnified Person, the Borrower's indemnification obligations
under this Section 9.2 shall include the obligation to defend such Indemnified
Person using legal counsel satisfactory to such Indemnified Person, at the sole
cost and expense of the Borrower.  All amounts owing under this Section 9.2
shall be paid within 30 days after demand.

                                      -50-
<PAGE>

          (d)  Contribution. To the extent that any undertaking in the preceding
               ------------
paragraphs of this Section 9.2 may be unenforceable because it is violative of
any law or public policy, the Borrower will contribute the maximum portion that
it is permitted to pay and satisfy under applicable Law to the payment and
satisfaction of such undertaking.

          (e)  Settlement.  So long as the Borrower is in compliance with its
               ----------
obligations under this Section 9.2, the Borrower shall not be liable to any
Indemnified Person under this Section 9.2 for any settlement made by such
Indemnified Person without the Borrower's consent.

          9.3  Notices.  (a)  All notices, requests and other communications
               -------
provided for hereunder shall be in writing (including, unless the context
expressly otherwise provides, by facsimile transmission, provided that any
                                                         --------
matter transmitted by the Borrower by facsimile (i) shall be immediately
confirmed by a telephone call to the recipient at the number specified on
Schedule 9.3, and (ii) shall be followed promptly by a hard copy original
thereof by express courier) and faxed or delivered, to the address or facsimile
number specified for notices on Schedule 9.3 or to such other address as shall
be designated by such party in a written notice to the other parties hereto.

          (b)  All such notices, requests and communications (i) sent by express
courier will be effective upon delivery to or refusal to accept delivery by the
addressee, and (ii) transmitted by facsimile will be effective when sent and
facsimile confirmation received; except that all notices and other
communications to the Administrative Agent or any Lender shall not be effective
until actually received.

          (c)  The Borrower acknowledges and agrees that any agreement of the
Administrative Agent or any Lender to receive certain notices by telephone and
facsimile is solely for the convenience and at the request of the Borrower.  The
Administrative Agent and each Lender shall be entitled to rely on the authority
of any Person purporting to be a Person authorized by the Borrower to give such
notice and the Administrative Agent and each Lender shall not have any liability
to the Borrower or other Person on account of any action taken or not taken by
any of the Administrative Agent or such Lender in reliance upon such telephonic
or facsimile notice.

          9.4  Benefit of Agreement.  This Agreement shall be binding upon and
               --------------------
inure to the benefit of and be enforceable by the respective successors and
permitted assigns of the parties hereto.  The Borrower may not assign or
otherwise transfer any of its rights under this Agreement or any of the other
Financing Documents.

          9.5  No Waiver; Remedies Cumulative.  No failure or delay on the part
               ------------------------------
of the Administrative Agent or any Lender or the holder of any Note in
exercising any right, power or privilege hereunder or under any other Financing
Document and no course of dealing between the Borrower and the Administrative
Agent or any Lender or the holder of any Note shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or privilege
hereunder or under any other Financing Document preclude any other or further
exercise thereof or the exercise of any other right, power or privilege
hereunder or thereunder.  No notice to or demand on the Borrower in any case
shall entitle the Borrower to any other or further notice or demand in

                                      -51-
<PAGE>

similar or other circumstances or constitute a waiver of the rights of the
Administrative Agent or any Lender or the holder of any Note to take any other
or further action in any circumstances without notice or demand. All remedies,
either under this Agreement or any other Financing Document or pursuant to any
applicable Law or otherwise afforded to the Administrative Agent or any Lender
shall be cumulative and not alternative.

          9.6  No Third Party Beneficiaries.  The agreement of any Lender to
               ----------------------------
make extensions of credit to the Borrower on the terms and conditions set forth
in this Agreement and the other Financing Documents is solely for the benefit of
the Borrower, and no other Person shall have any rights hereunder against such
Lender with respect to the Loans, the proceeds thereof or otherwise.

          9.7  Reinstatement.  To the extent that the Administrative Agent or
               -------------
any Lender receives any payment by or on behalf of the Borrower, which payment
or any part thereof is subsequently invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to the Borrower or to its
estate, trustee, receiver, custodian or any other party under any Bankruptcy Law
or otherwise, then to the extent of the amount so required to be repaid, the
obligation or part thereof which has been paid, reduced or satisfied by the
amount so repaid shall be reinstated by the amount so repaid and shall be
included within the Obligations as of the date such initial payment, reduction
or satisfaction occurred.

          9.8  No Immunity.  To the extent that the Borrower may be entitled, in
               -----------
any jurisdiction in which judicial proceedings may at any time be commenced with
respect to this Agreement or any other Financing Document, to claim for itself
or its revenues, assets or Properties any immunity from suit, the jurisdiction
of any court, attachment prior to judgment, attachment in aid of execution of
judgment, set-off, execution of a judgment or any other legal process, and to
the extent that in any such jurisdiction there may be attributed to such Person
such an immunity (whether or not claimed), the Borrower hereby irrevocably
agrees not to claim and hereby irrevocably waives such immunity to the fullest
extent permitted by the Law of the applicable jurisdiction.

          9.9  Counterparts.  This Agreement may be executed in any number of
               ------------
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered by facsimile or otherwise shall be an
original, but all of which shall together constitute one and the same
instrument.

          9.10 Amendment or Waiver.  (a)  No provision of this Agreement or any
               -------------------
other Financing Document may be amended, supplemented, modified or waived,
except by a written instrument signed by the Required Waiver Lenders and the
Borrower and each Covered Party that is a party thereto, and, to the extent that
its rights or obligations may be affected thereby, the Administrative Agent.
Notwithstanding the foregoing provisions, no such waiver and no such amendment,
supplement or modification shall (i) increase or extend the Commitment of any
Lender (it being understood that waivers or modifications after the Closing Date
of covenants, Defaults or Events of Default shall not constitute a change in the
terms of any Commitment of any Lender), without the prior written consent of
such Lender, (ii) postpone or delay any date fixed by this Agreement or any
other Financing Document for any payment of principal, interest, fees or

                                      -52-
<PAGE>

other amounts due to any Lender hereunder or under any other Financing Document
(it being understood that waivers or modifications after the Closing Date of
covenants, Defaults or Events of Default shall not constitute a postponement or
delay in any date fixed by this Agreement or any other Financing Document for
any payment of principal, interest, fees or other amounts due to any Lender
hereunder or under any other Financing Document), without the prior written
consent of such Lender, (iii) reduce the principal of, or the rate of interest
specified in any Financing Document on, any Loan of any Lender, without the
prior written consent of such Lender, (iv) release all or substantially all of
the Collateral except as shall be otherwise provided in any Security Document or
other Financing Document or consent to the assignment or transfer by the
Borrower of any of its respective obligations under this Agreement or any other
Financing Document, without the prior written consent of each Lender, (v) amend,
modify or waive any provision of this Section 9.10 or Section 9.1 or 9.2,
without the prior written consent of each Lender, or (vi) reduce the percentage
specified in or otherwise amend the definition of Required Waiver Lenders or
Required Acceleration Lenders, without the prior written consent of each Lender.

          (b)   Any waiver and any amendment, supplement or modification made or
entered into in accordance with Section 9.10(a) shall be binding upon the
Borrower, the Administrative Agent, the Lenders and their successors and
assigns.

          9.11  Assignments, Participations, etc.  (a)  Each Lender may, without
                ---------------------------------
the consent of the Borrower, but with prior notice to the Administrative Agent,
sell or assign any part of the Loan of such Lender and the other rights and
obligations of such Lender to any Person or any assignee thereof (an "Assignee")
unless the sale or assignment of the Loan and such other rights and obligations
of such Lender would reasonably put the business of the Borrower at a
competitive disadvantage, then such sale or assignment shall require the consent
of the Borrower. The assigning Lender and the Assignee shall enter into an
assignment agreement, in form and substance satisfactory to the Administrative
Agent (an "Assignment and Acceptance"), with respect to the sale or assignment
           -------------------------
of the Loan to be assigned and, subject to paragraphs (e) and (f) of this
Section 9.11, upon execution and delivery of such Assignment and Acceptance, (i)
the Assignee thereunder shall be a party hereto and, to the extent that rights
and obligations hereunder have been assigned to it pursuant to such Assignment
and Acceptance, shall have the rights and obligations of a Lender hereunder and
under the other Financing Documents, and this Agreement shall be deemed to be
amended to the extent, but only to the extent, necessary to effect the addition
of the Assignee, and any reference to the assigning Lender hereunder or under
the other Financing Documents shall thereafter refer to such Lender and to the
Assignee to the extent of their respective interests, and (ii) the assigning
Lender shall, to the extent that rights and obligations hereunder and under the
other Financing Documents have been assigned by it pursuant to such assignment
agreement, relinquish its rights and be released from its obligations under the
Financing Documents.

          (b)   Each Lender may sell participations to one or more banks or
other entities (other than the Borrower or any of its Affiliates) in or to all
or a portion of its rights and obligations under this Agreement and such
Lender's Note; provided, however, 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,
(iii) such Lender

                                      -53-
<PAGE>

shall remain the holder of any such Note for all purposes of this Agreement,
(iv) the Borrower 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 and (v) no participant under any such
participation shall have any right to approve any amendment or waiver of any
provision of this Agreement or any Note, or any consent to any departure by the
Borrower therefrom, except to the extent that such amendment, waiver or consent
would reduce the principal of, or interest on, the Note or any fees or other
amounts payable hereunder, or release of all or substantially all of the
Collateral, in each case to the extent subject to such participation, or
postpone any date fixed for any payment of principal of, or interest on, the
Notes or any fees or other amounts payable hereunder, in each case to the extent
subject to such participation.

          (c)  A Lender may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this Section 9.11, disclose
to the assignee or participant or proposed assignee or participant, any
information relating to the Borrower furnished to such Lender by or on behalf of
the Borrower; provided, that prior to any such disclosure, the assignee or
              --------
participant or proposed assignee or participant shall agree to preserve the
confidentiality of any confidential information relating to the Borrower
received by it from such Lender.

          (d)  Notwithstanding any other provision contained in this Agreement
or any other Financing Document to the contrary, any Lender may assign all or
any portion of the Loan held by it as collateral security, provided that any
                                                           --------
payment in respect of such assigned Loan or Note made by the Borrower to or for
the account of the assigning or pledging Lender in accordance with the terms of
this Agreement shall satisfy the Borrower's obligations hereunder in respect to
such assigned Loan or Note to the extent of such payment. No such assignment
shall release the assigning Lender from its obligations hereunder.

          (e)  The Borrower hereby designates the Administrative Agent to serve
as the Borrower's agent, solely for purposes of this Section 9.11, to maintain a
register (the "Register") on which it will record the Loans made by each of the
Lenders and each repayment in respect of the principal amount of the Loans of
each Lender.  Failure to make any such recordation, or any error in such
recordation shall not affect the Borrower's obligations in respect of such
Loans.  With respect to any Lender, the transfer of the rights to the principal
of, and interest on, any Loan shall not be effective until such transfer is
recorded on the Register maintained by the Administrative Agent with respect to
ownership of such Loans and prior to such recordation all amounts owing to the
transferor with respect to such Loans shall remain owing to the transferor.  The
registration of assignment or transfer of all or part of any Loans shall be
recorded by the Administrative Agent on the Register only upon the acceptance by
the Administrative Agent of a properly executed and delivered Assignment and
Acceptance pursuant to Section 9.11(a).  The Borrower agrees to indemnify the
Administrative Agent from and against any and all losses, claims, damages and
liabilities of whatsoever nature which may be imposed on, asserted against or
incurred by the Administrative Agent in performing its duties under this Section
9.11(e).

          (f)  Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an Assignee (and, in any case where the consent of the
Borrower is required by this Section, by the Borrower) together with payment to
the Administrative Agent of a registration and processing fee of $3,500, the
Administrative Agent shall (i) promptly accept such

                                      -54-
<PAGE>

Assignment and Acceptance and (ii) on the effective date determined pursuant
thereto record the information contained therein in the Register and give notice
of such acceptance and recordation to the Borrower. On or prior to such
effective date, the Borrower, at its own expense, upon request, shall execute
and deliver to the Administrative Agent (in exchange for the Note of the
assigning Lender) a new Note to the order of such Assignee in an amount equal to
the Loan acquired by it pursuant to such Assignment and Acceptance and, if such
assigning Lender has retained a Loan, a new Note to the order of such assigning
Lender in an amount equal to the Loan retained by it hereunder.

          9.12  Survival.  All indemnities set forth herein, including, without
                --------
limitation, Section 9.2, shall survive the execution and delivery of this
Agreement and the Notes and the making and repayment of the Loans.  In addition,
each representation and warranty made or deemed to be made pursuant hereto shall
survive the making of such representation and warranty, and no Lender shall be
deemed to have waived, by reason of making any extension of credit, any Default
or Event of Default which may arise by reason of such representation or warranty
proving to have been false or misleading, notwithstanding that such Lender may
have had notice or knowledge or reason to believe that such representation or
warranty was false or misleading at the time such extension of credit was made.

          9.13  WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO HEREBY
                --------------------
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES THE RIGHT ANY OF THEM MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON, OR ARISING OUT OF,
UNDER OR IN CONNECTION WITH, THIS AGREEMENT, THE NOTES OR ANY OTHER FINANCING
DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY RELATING HERETO OR THERETO.  THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE LENDERS TO ENTER INTO THIS AGREEMENT.

          9.14  Right of Set-off.  In addition to any rights now or hereafter
                ----------------
granted under applicable Law or otherwise, and not by way of limitation of any
such rights, upon the occurrence of an Event of Default, each Lender is hereby
authorized at any time or from time to time, without presentment, demand,
protest or other notice of any kind to the Borrower or to any other Person, any
such notice being hereby expressly waived, to set off and to appropriate and
apply any and all deposits (general or special) and any other Indebtedness at
any time held or owing by such Lender (including without limitation by branches
and agencies of such Lender wherever located), to or for the credit or the
account of the Borrower against and on account of the Obligations or liabilities
of the Borrower to such Lender under this Agreement or any of the other
Financing Documents, including all claims of any nature or description arising
out of or connected with this Agreement or any other Financing Document,
irrespective of whether such Lender shall have made any demand hereunder and
although said Obligations, liabilities or claims, or any of them, shall be
contingent or unmatured.

          9.15  Severability.  Any provision hereof which is prohibited or
                ------------
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or

                                      -55-
<PAGE>

unenforceability without invalidating the remaining provisions hereof and
without affecting the validity or enforceability of any provision in any other
jurisdiction.

          9.16  Governing Law; Submission to Jurisdiction.  (a)  THIS AGREEMENT
                -----------------------------------------
AND EACH OF THE OTHER FINANCING DOCUMENTS (UNLESS SUCH DOCUMENT EXPRESSLY STATES
OTHERWISE THEREIN) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAW RULES THEREOF
(OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

          (b)  The Borrower hereby submits to the nonexclusive jurisdiction of
the United States District Court for the Southern District of New York and of
any New York State court sitting in New York City for the purposes of all legal
proceedings arising out of or relating to this Agreement, any other Financing
Document or the transactions contemplated hereby or thereby. The Borrower hereby
irrevocably waives, to the fullest extent permitted by applicable Law, any
objection which it may now or hereafter have to the laying of the venue of any
such proceeding brought in such a court and any claim that any such proceeding
brought in such a court has been brought in an inconvenient forum. The Borrower
hereby irrevocably appoints CT Corporation System (the "Process Agent"), with
                                                        -------------
an office on the date hereof at 111 Eighth Avenue, New York, New York 10011, as
its agent to receive on its behalf and on behalf of its Property, service of
copies of the summons and complaint and any other process that may be served in
any such action or proceeding. Service upon the Process Agent shall be deemed to
be personal service on the Borrower and shall be legal and binding upon the
Borrower for all purposes notwithstanding any failure to mail copies of such
legal process to the Borrower, or any failure on the part of the Borrower to
receive the same. Nothing herein shall affect the right to serve process in any
other manner permitted by applicable Law or any right to bring legal action or
proceedings in any other competent jurisdiction, including judicial or non-
judicial foreclosure of real property interests which are part of the
Collateral. The Borrower further agrees that the aforesaid courts of the State
of New York and of the United States of America for the Southern District of New
York shall have exclusive jurisdiction with respect to any claim or counterclaim
of the Borrower based upon the assertion that the rate of interest charged by or
under this Agreement or under the other Financing Documents is usurious. To the
extent permitted by applicable Law, the Borrower further irrevocably agrees to
the service of process of any of the aforementioned courts in any suit, action
or proceeding by the mailing of copies thereof by certified mail, postage
prepaid, return receipt requested, to the Borrower at the address referenced in
Section 9.3, such service to be effective upon the date indicated on the postal
receipt returned from the Borrower.

          (c)  The Borrower agrees that it will at all times continuously
maintain an agent to receive service of process in the State of New York on
behalf of itself and its Properties, and, in the event that for any reason the
agent mentioned above shall not serve as agent for the Borrower to receive
service of process in the State of New York on its behalf, the Borrower shall
promptly appoint a successor satisfactory to the Administrative Agent so to
serve, advise the Administrative Agent thereof, and deliver to the
Administrative Agent evidence in writing of the successor agent's acceptance of
such appointment. The foregoing provisions constitute, among other things, a
special arrangement for service among the parties to this Agreement for the
purposes of 28 U.S.C. (S) 1608.

          SECTION 10.   THE ADMINISTRATIVE AGENT; THE LEAD ARRANGER, THE CO-
                        ---------------------------------------------------
ARRANGER AND THE BOOK MANAGER.
-----------------------------

          10.1  Appointment.  Lehman Commercial Paper Inc. shall be the
                -----------
Administrative Agent and shall act as specified herein and in the other
Financing Documents.  Each Lender hereby irrevocably authorizes, and the holder
of any Note by the acceptance of such Note shall be deemed irrevocably to
authorize, the Administrative Agent to take such action on its behalf under the
provisions of this Agreement, the other Financing Documents and any other
instruments and agreements referred to herein or therein and to exercise such
powers and to perform such duties hereunder and thereunder as are specifically
delegated to or required of the Administrative Agent by the terms hereof and
thereof and such other powers as are reasonably incidental thereto.  The
Administrative Agent may perform any of its duties hereunder by or through its
officers, directors, agents or employees.

          10.2  Nature of Duties.  The Administrative Agent shall have no duties
                ----------------
or responsibilities except those expressly set forth in this Agreement and the
Security Documents.  Neither the Administrative Agent nor any of its officers,
directors, agents or employees shall be liable for any action taken or omitted
by it or them hereunder or under any other Financing Document or in connection
herewith or therewith, unless caused by its or their gross negligence or willful
misconduct.  The duties of the Administrative Agent shall be mechanical and
administrative in nature; the Administrative Agent shall not have by reason of
this Agreement or any other Financing Document, or by reason of the use of the
term "agent" with reference to the Administrative Agent, a fiduciary
relationship in respect of any Lender or the holder of any Note; and nothing in
this Agreement or any other Financing Document, expressed or implied, is
intended to or shall be so construed as to impose upon the Administrative Agent
any obligations in respect of this Agreement or any other Financing Document
except as expressly set forth herein.

          10.3  Lack of Reliance on the Administrative Agent.  Independently and
                --------------------------------------------
without reliance upon the Administrative Agent, each Lender and each holder of
any Note, to the extent it

                                      -58-
<PAGE>

deems appropriate, has made and shall continue to make (i) its own independent
investigation of the financial condition and affairs of the Borrower in
connection with the making and the continuance of the Loans and the taking or
not taking of any action in connection herewith and (ii) its own appraisal of
the creditworthiness of the Borrower, except as expressly provided in this
Agreement, the Administrative Agent shall have no duty or responsibility, either
initially or on a continuing basis, to provide any Lender or the holder of any
Note with any credit or other information with respect thereto, whether coming
into its possession before the making of the Loans or at any time or times
thereafter. The Administrative Agent shall not be responsible to any Lender or
the holder of any Note for any recitals, statements, information,
representations or warranties herein or in any document, certificate or other
writing delivered in connection herewith or for the execution, effectiveness,
genuineness, validity, enforceability, perfection, collectibility, priority or
sufficiency of this Agreement or any other Financing Document or the financial
condition of the Borrower or be required to make any inquiry concerning either
the performance or observance of any of the terms, provisions or conditions of
this Agreement or any other Financing Document, or the financial condition of
the Borrower or the existence or possible existence of any Default or Event of
Default.

          10.4  Certain Rights of the Administrative Agent.  If the
                ------------------------------------------
Administrative Agent shall request instructions from the Required Waiver Lenders
or Required Acceleration Lenders, as the case may be, with respect to any act or
action (including failure to act) in connection with this Agreement or any other
Financing Document, the Administrative Agent shall be entitled to refrain from
such act or taking such action unless and until the Administrative Agent shall
have received instructions from the Required Waiver Lenders or Required
Acceleration Lenders, as the case may be, and the Administrative Agent shall not
incur liability to any Person by reason of so refraining. Without limiting the
foregoing, no Lender or the holder of any Note shall have any right of action
whatsoever against the Administrative Agent as a result of the Administrative
Agent acting or refraining from acting hereunder or under any other Financing
Document in accordance with the instructions of the Required Waiver Lenders or
Required Acceleration Lenders, as the case may be.

          10.5  Reliance.  The Administrative Agent shall be entitled to rely,
                --------
and shall be fully protected in relying, upon any note, writing, resolution,
notice, statement, certificate, telex, teletype or telecopier message,
cablegram, radiogram, order or other document or telephone message signed, sent
or made by any Person that the Administrative Agent believed to be the proper
Person, and, with respect to all legal matters pertaining to this Agreement and
any other Financing Document its duties hereunder and thereunder, upon advice of
counsel selected by it.

          10.6  Indemnification.  To the extent the Administrative Agent is not
                ---------------
reimbursed and indemnified by the Borrower, each Lender will reimburse and
indemnify the Administrative Agent, in proportion to its respective Loan, for
and against any and all liabilities, obligations, losses, damages, penalties,
claims, actions, judgments, suits, costs, expenses or disbursements of
whatsoever kind or nature which may be imposed on, asserted against or incurred
by the Administrative Agent in performing its duties hereunder or under any
other Financing Document, or in any way relating to or arising out of this
Agreement or any other Financing Document; provided, however, that no Lender
shall be liable for any portion of such liabilities, obligations,

                                      -59-
<PAGE>

losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Administrative Agent's gross negligence or
willful misconduct.

          10.7   The Administrative Agent in its Individual Capacity.  With
                 ---------------------------------------------------
respect to its obligation to make Loans under this Agreement, and with respect
to any Loan held by it or made by it, the Administrative Agent shall have the
rights and powers specified herein for a "Lender" and may exercise the same
rights and powers as though it were not performing the duties specified herein;
and the term "Lender," "Required Waiver Lenders", "Required Acceleration
Lenders", "holder of Note" or any similar terms shall, unless the context
clearly otherwise indicates, include the Administrative Agent in its individual
capacity. The Administrative Agent may accept deposits from, lend money to, and
generally engage in any kind of banking, trust or other business with the
Borrower or any Affiliate of the Borrower as if it were not performing the
duties specified herein, and may accept fees and other consideration from the
Borrower for services in connection with this Agreement and otherwise without
having to account for the same to the Lenders.

          10.8   Holders.  The Administrative Agent may deem and treat the payee
                 -------
of any Note as the owner thereof for all purposes hereof unless and until a
written notice of the assignment, transfer or endorsement thereof, as the case
may be, shall have been filed with the Administrative Agent.  Any request,
authority or consent of any Person who, at the time of making such request or
giving such authority or consent, is the holder of any Note shall be conclusive
and binding on any subsequent holder, transferee, assignee or indorsee, as the
case may be, of such Note or of any Note or Notes issued in exchange therefor.

          10.9   Resignation by the Administrative Agent.  (a)  The
                 ---------------------------------------
Administrative Agent may resign from the performance of all its functions and
duties hereunder and/or under the other Financing Documents at any time by
giving 15 Business Days' prior written notice to the Borrower and each Lender.
Such resignation shall take effect upon the appointment of a successor
Administrative Agent pursuant to clauses (b) and (c) below or as otherwise
provided below.

          (b)    Upon any such notice of resignation, the Required Waiver
Lenders shall appoint a successor Administrative Agent hereunder or thereunder
who shall be a commercial bank, trust company or other financial institution
which is a Lender and which (unless an Event of Default shall be continuing)
shall be subject to the reasonable approval of the Borrower.

          (c)    If a successor Administrative Agent shall not have been so
appointed within such 15 Business Day period, the Administrative Agent, with the
consent of the Borrower, may then appoint a successor Administrative Agent who
shall serve as Administrative Agent hereunder or thereunder until such time, if
any, as the Required Waiver Lenders appoint a successor Administrative Agent as
provided above.

          (d)    If no successor Administrative Agent has been appointed
pursuant to clause (b) or (c) above by the 20th Business Day after the date such
notice of resignation was given by the Administrative Agent, the Administrative
Agent's resignation shall become effective and the Required Waiver Lenders shall
thereafter perform all the duties of the Administrative

                                      -60-
<PAGE>

Agent hereunder and/or under any other Financing Document until such time, if
any, as the Required Waiver Lenders appoint a successor Administrative Agent as
provided above.

          10.10  The Lead Arranger, Co-Arranger and Book Manager.  None of the
                 -----------------------------------------------
Lead Arranger, the Co-Arranger and the Book Manager, in such respective
capacities, shall have any duties or responsibilities under this Agreement or
any other Financing Document, nor shall any of such Persons, in such respective
capacities, have any obligations or liabilities hereunder or under any other
