listed in this Section 1.1 shall have the respective meanings set forth in this
Section 1.1.

                  "Administrative Agent": as defined in the preamble hereto.

                  "Affiliate": as to any Person, any other Person that, directly
or indirectly, is in control of, is controlled by, or is under common control
with, such Person. For purposes of this definition, "control" of a Person means
the power, directly or indirectly, either to (a) vote 10% or more of the

persons performing similar functions) of such Person or (b) direct or cause the
direction of the management and policies of such Person, whether by contract or
otherwise.

                  "Aggregate Exposure": with respect to any Lender at any time,
an amount equal to (a) until the Closing Date, the aggregate amount of such
Lender's Commitments at such time and (b) thereafter, the amount of such
Lender's Commitment then in effect or, if the Revolving Commitments have been
terminated, the amount of such Lender's Loans then outstanding.

                  "Aggregate Exposure Percentage": with respect to any Lender at
any time, the ratio (expressed as a percentage) of such Lender's Aggregate
Exposure at such time to the sum of the Aggregate Exposures of all Lenders at

Dispositions of Property (excluding any such Disposition permitted by clause
(a), (b), (c), (d) or (e) of Section 6.5) which yields gross proceeds to the

thereof in the case of non-cash proceeds consisting of notes or other debt
securities and valued at fair market value in the case of other non-cash
proceeds) in excess of $1,000,000.

lending rate as set forth on the British Banking Association Telerate Page 5 (or
such other comparable page as may, in the opinion of the Administrative Agent,
replace such page for the purpose of displaying such rate), as in effect from
time to time. Any change in the Base Rate due to a change in the Prime Rate or

business on the effective day of such change in the Prime Rate or the Federal
Funds Effective Rate, respectively.

and conditions hereof, each Lender severally agrees to make revolving credit
loans ("Loans") to the Borrower from time to time during the Revolving
Commitment Period in an aggregate principal amount at any one time outstanding
which does not exceed the amount of such Lender's Commitment. During the
Revolving Commitment Period the Borrower may use the Commitments by borrowing,
prepaying the Loans in whole or in part, and reborrowing, all in accordance with
the terms and conditions hereof. The Loans may from time to time be Eurodollar
Loans or Base Rate Loans, as determined by the Borrower and notified to the
Administrative Agent in accordance with Sections 2.2 and 2.8.

                  2.2      Procedure for Revolving Loan Borrowing(a) . The
Borrower may borrow under the Commitments during the Revolving Commitment Period
on any Business Day,

<PAGE>

                                                                              15

provided that the Borrower shall give the Administrative Agent irrevocable
notice (which notice must be received by the Administrative Agent prior to 10:00
A.M., New York City time, (a) two Business Days prior to the requested Borrowing
Date, in the case of Eurodollar Loans, or (b) one Business Day prior to the
requested Borrowing Date, in the case of Base Rate Loans), specifying (i) the
amount and Type of Loans to be borrowed, (ii) the requested Borrowing Date and
(iii) in the case of Eurodollar Loans, the respective amounts of each such Type
of Loan and the respective lengths of the initial Interest Period therefor. Each
borrowing under the Commitments shall be in an amount equal to (x) in the case
of Base Rate Loans, $1,000,000 or a whole multiple thereof (or, if the then
aggregate Available Commitments are less than $1,000,000, such lesser amount)
and (y) in the case of Eurodollar Loans, $5,000,000 or a whole multiple of
$1,000,000 in excess thereof. Upon receipt of any such notice from the Borrower,
the Administrative Agent shall promptly notify each Lender thereof. Each Lender
will make the amount of its pro rata share of each borrowing available to the
Administrative Agent for the account of the Borrower at the Funding Office prior
to 12:00 Noon, New York City time, on the Borrowing Date requested by the
Borrower in funds immediately available to the Administrative Agent. Such
borrowing will then be made available to the Borrower by the Administrative
Agent crediting the account of the Borrower on the books of such office with the
aggregate of the amounts made available to the Administrative Agent by the
Lenders and in like funds as received by the Administrative Agent.

                  2.3      Fees, etc. (a) The Borrower agrees to pay to the
Arranger on the Revolving Credit Termination Date a fee in an amount equal to
0.50% of each Lender's average daily Commitment, regardless of usage, in effect
on such date.

                  (b)      The Borrower agrees to pay to the Administrative
Agent on August 29, 2003 a fee in an amount equal to 0.50% of the greater of the
Total Loans outstanding on such date and the Total Commitments in effect on such
date.

                  2.4      Termination or Reduction of Commitments. The Borrower
shall have the right, upon not less than two Business Days' notice to the
Administrative Agent, to terminate the Commitments or, from time to time, to
reduce the amount of the Commitments; provided that no such termination or
reduction of Commitments shall be permitted if, after giving effect thereto and
to any prepayments of the Loans made on the effective date thereof, the Total
Loans would exceed the Total Commitments. Any such reduction shall be in an
amount equal to $1,000,000, or a whole multiple thereof, and shall reduce
permanently the Commitments then in effect.

                  2.5      Repayment of Loans; Evidence of Debt. (a) The
Borrower hereby unconditionally promises to pay to the Administrative Agent for
the account of each Lender the principal amount of each Loan of such Lender as
may be outstanding on the Revolving Credit Termination Date (or such earlier
date on which the Loans become due and payable pursuant to Section 7). The
Borrower hereby further agrees to pay interest on the unpaid principal amount of
the Loans from time to time outstanding from the date hereof until payment in
full thereof at the rates per annum, and on the dates, set forth in Section
2.10.

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

<PAGE>

                                                                              16

to such Lender from time to time under this Agreement.

                  (c)      The Administrative Agent, on behalf of the Borrower,
shall maintain the Register pursuant to Section 9.6(d), and a subaccount therein
for each Lender, in which shall be recorded (i) the amount of each Loan made
hereunder and any Revolving Credit Note evidencing such Loan, the Type of such
Loan and each 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) both the amount of any sum received
by the Administrative Agent hereunder from the Borrower and each Lender's share
thereof.

                  (d)      The entries made in the Register and the accounts of
each Lender maintained pursuant to Section 2.5(c) shall, to the extent permitted
by applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain the Register or
any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans made to
the Borrower by such Lender in accordance with the terms of this Agreement.

                  (e)      The Borrower agrees that, upon the request to the
Administrative Agent by any Lender, the Borrower will execute and deliver to
such Lender (i) a promissory note of the Borrower evidencing the Revolving
Credit Loans of such Lender, substantially in the form of Exhibit F attached
hereto with appropriate insertions as to date and principal amount (a "Revolving
Credit Note").

                  2.6      Optional Prepayments. The Borrower may at any time
and from time to time prepay the Loans, in whole or in part, without premium or
penalty except as otherwise provided herein, upon irrevocable notice delivered
to the Administrative Agent at least three Business Days prior thereto in the
case of Eurodollar Loans and at least one Business Day prior thereto in the case
of Base Rate Loans, which notice shall specify the date and amount of such
prepayment, and whether such prepayment is of Eurodollar Loans or Base Rate
Loans; provided, that if a Eurodollar Loan is prepaid on any day other than the
last day of the Interest Period applicable thereto, the Borrower shall also pay
any amounts owing pursuant to Section 2.16. If any such notice is given, the
amount specified in such notice shall be due and payable on the date specified
therein, together with accrued interest to such date on the amount prepaid.
Partial prepayments of Loans shall be in an aggregate principal amount of
$1,000,000 or a whole multiple thereof.

                  2.7      Mandatory Prepayments. (a) If any Indebtedness shall
be incurred by the Borrower or any of its Subsidiaries (excluding any
Indebtedness incurred in accordance with Section 6.2 as in effect on the date of
this Agreement), then, on the date of such incurrence, the Commitments shall be
reduced by an amount equal to the amount of the Net Cash Proceeds of such
incurrence, and the Loans shall be prepaid to the extent, if any, that the
aggregate then outstanding principle amount thereof exceeds the Commitments as
so reduced. The provisions of the paragraph do not constitute a consent to the
incurrence of any Indebtedness not permitted by Section 6.2.

                  (b)      If any Capital Stock shall be issued by the Borrower
(excluding any

<PAGE>

                                                                              17

Capital Stock issued to Resources and any capital contributions received by the
Borrower from Resources), then, on the date of such issuance, the Commitments
shall be reduced by an amount equal to 50% of the amount of the Net Cash
Proceeds of such issuance, and the Loans shall be prepaid to the extent, if any,
that the aggregate then outstanding principle amount thereof exceeds the
Commitments as so reduced. The provisions of the paragraph do not constitute a
consent to any Change of Control.

                  (c)      The application of any prepayment pursuant to this
Section 2.7 shall be made, first, to Base Rate Loans and, second, to Eurodollar
Loans. Each prepayment of the Loans under this Section 2.7 shall be accompanied
by accrued interest to the date of such prepayment on the amount prepaid.

                  2.8      Conversion and Continuation Options. (a) The Borrower
may elect from time to time to convert Eurodollar Loans to Base Rate Loans by
giving the Administrative Agent at least two Business Days' prior irrevocable
notice of such election, provided that any such conversion of Eurodollar Loans
may be made only on the last day of an Interest Period with respect thereto. The
Borrower may elect from time to time to convert Base Rate Loans to Eurodollar
Loans by giving the Administrative Agent at least two Business Days' prior
irrevocable notice of such election (which notice shall specify the length of
the initial Interest Period therefor), provided that no Base Rate Loan may be
converted into a Eurodollar Loan (i) when any Event of Default has occurred and
is continuing and the Administrative Agent has, or the Required Lenders have,
determined in its or their sole discretion not to permit such conversions or
(ii) after the date that is one month prior to the final scheduled maturity date
of the Loans. Upon receipt of any such notice the Administrative Agent shall
promptly notify each relevant Lender thereof.

                  (b)      The Borrower may elect to continue any Eurodollar
Loan as such upon the expiration of the then current Interest Period with
respect thereto by giving irrevocable notice to the Administrative Agent, in
accordance with the applicable provisions of the term "Interest Period" set
forth in Section 1.1, of the length of the next Interest Period to be applicable
to such Loans, provided that no Eurodollar Loan may be continued as such (i)
when any Event of Default has occurred and is continuing and the Administrative
Agent has, or the Required Lenders have, determined in its or their sole
discretion not to permit such continuations or (ii) after the date that is one
month prior to the final scheduled maturity date of the Loans, and provided,
further, that if the Borrower shall fail to give any required notice as
described above in this paragraph or if such continuation is not permitted
pursuant to the preceding proviso, such Loans shall be converted automatically
to Base Rate Loans on the last day of such then expiring Interest Period. Upon
receipt of any such notice the Administrative Agent shall promptly notify each
relevant Lender thereof.

                  2.9      Minimum Amounts and Maximum Number of Eurodollar
Tranches. Notwithstanding anything to the contrary in this Agreement, all
borrowings, conversions, continuations and optional prepayments of Eurodollar
Loans and all selections of Interest Periods shall be in such amounts and be
made pursuant to such elections so that, (a) after giving effect thereto, the
aggregate principal amount of the Eurodollar Loans comprising each Eurodollar
Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess
thereof and (b) no more than ten Eurodollar Tranches shall be outstanding at any
one time.

                                                                              18

                  2.10     Interest Rates and Payment Dates. (a) Each Eurodollar
Loan shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

                  (b)      Each Base Rate Loan shall bear interest for each day
on which it is outstanding at a rate per annum equal to the Base Rate in effect
for such day plus the Applicable Margin.

                  (c)      (i) If all or a portion of the principal amount of
any Loan shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), all outstanding Loans (whether or not overdue) shall
bear interest (to the extent legally permitted) at a rate per annum that is
equal to the rate that would otherwise be applicable thereto pursuant to the
foregoing provisions of this Section plus 2% and (ii) if all or a portion of any
interest payable on any Loan or any fee or other amount payable hereunder shall
not be paid when due (whether at the stated maturity, by acceleration or
otherwise), such overdue amount shall bear interest at a rate per annum equal to
the rate then applicable to Base Rate Loans plus 2%, in each case, with respect
to clauses (i) and (ii) above, from the date of such non-payment until such
amount is paid in full (after as well as before judgment).

                  (d)      Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (c) of this
Section shall be payable from time to time on demand.

                  2.11     Computation of Interest and Fees. (a) Interest and
fees payable pursuant hereto shall be calculated on the basis of a 360-day year
for the actual days elapsed, except that, with respect to Base Rate Loans on
which interest is calculated on the basis of the Prime Rate, the interest
thereon shall be calculated on the basis of a 365- (or 366-, as the case may be)
day year for the actual days elapsed. The Administrative Agent shall as soon as
practicable notify the Borrower and the relevant Lenders of each determination
of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the Base Rate or the Eurocurrency Reserve Requirements shall become
effective as of the opening of business on the day on which such change becomes
effective. The Administrative Agent shall as soon as practicable notify the
Borrower and the relevant Lenders of the effective date and the amount of each
such change in interest rate.

                  (b)      Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the
Administrative Agent in determining any interest rate pursuant to Section
2.10(a).

                  2.12     Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

                  (a)      the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining the Eurodollar

<PAGE>

                                                                              19

Rate for such Interest Period, or

                  (b)      the Administrative Agent shall have received notice
from the Required Lenders that the Eurodollar Rate determined or to be
determined for such Interest Period will not adequately and fairly reflect the
cost to such Lenders (as conclusively certified by such Lenders) of making or
maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant Lenders as soon as practicable thereafter. If such
notice is given (x) any Eurodollar Loans requested to be made on the first day
of such Interest Period shall be made as Base Rate Loans, (y) any Loans that
were to have been converted on the first day of such Interest Period to
Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding
Eurodollar Loans shall be converted, on the last day of the then current
Interest Period with respect thereto, to Base Rate Loans. Until such notice has
been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be
made or continued as such, nor shall the Borrower have the right to convert
Loans to Eurodollar Loans.

                  2.13     Pro Rata Treatment and Payments. (a) Each borrowing
by the Borrower from the Lenders hereunder and any reduction of the Commitments
of the Lenders shall be made pro rata according to the respective Loan
Percentages of the Lenders.

                  (b)      Each payment (including each prepayment) by the
Borrower on account of principal of and interest on the Loans shall be made pro
rata according to the respective outstanding principal amounts of the Loans then
held by the Lenders.

                  (c)      All payments (including prepayments) to be made by
the Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without setoff or counterclaim and shall be made prior
to 12:00 Noon, New York City time, on the due date thereof to the Administrative
Agent, for the account of the relevant Lenders, at the Payment Office, in
Dollars and in immediately available funds. Any payment made by the Borrower
after 12:00 Noon, New York City time, on any Business Day shall be deemed to
have been on the next following Business Day. The Administrative Agent shall
distribute such payments to the Lenders promptly upon receipt in like funds as
received. If any payment hereunder (other than payments on the Eurodollar Loans)
becomes due and payable on a day other than a Business Day, such payment shall
be extended to the next succeeding Business Day. If any payment on a Eurodollar
Loan becomes due and payable on a day other than a Business Day, the maturity
thereof shall be extended to the next succeeding Business Day unless the result
of such extension would be to extend such payment into another calendar month,
in which event such payment shall be made on the immediately preceding Business
Day. In the case of any extension of any payment of principal pursuant to the
preceding two sentences, interest thereon shall be payable at the then
applicable rate during such extension.

                  (d)      Unless the Administrative Agent shall have been
notified in writing by any Lender prior to a borrowing that such Lender will not
make the amount that would constitute its share of such borrowing available to
the Administrative Agent, the Administrative Agent may assume that such Lender
is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a

                                                                              20

corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Administrative Agent, on demand, such amount with interest thereon at a
rate equal to the daily average Federal Funds Effective Rate for the period
until such Lender makes such amount immediately available to the Administrative
Agent. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
after such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
Base Rate Loans, on demand, from the Borrower.

                  (e)      Unless the Administrative Agent shall have been
notified in writing by the Borrower prior to the date of any payment due to be
made by the Borrower hereunder that the Borrower will not make such payment to
the Administrative Agent, the Administrative Agent may assume that the Borrower
is making such payment, and the Administrative Agent may, but shall not be
required to, in reliance upon such assumption, make available to the Lenders
their respective pro rata shares of a corresponding amount. If such payment is
not made to the Administrative Agent by the Borrower within three Business Days
after such due date, the Administrative Agent shall be entitled to recover, on
demand, from each Lender to which any amount which was made available pursuant
to the preceding sentence, such amount with interest thereon at the rate per
annum equal to the daily average Federal Funds Effective Rate. Nothing herein
shall be deemed to limit the rights of the Administrative Agent or any Lender
against the Borrower.

                  2.14     Requirements of Law. (a) If the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
or compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

                           (i)      shall subject any Lender to any tax of any
                                    kind whatsoever with respect to this
                                    Agreement or any Eurodollar Loan made by it,
                                    or change the basis of taxation of payments
                                    to such Lender in respect thereof (except
                                    for Non-Excluded Taxes covered by Section
                                    2.15 and changes in the rate of tax on the
                                    overall net income of such Lender);

                           (ii)     shall impose, modify or hold applicable any
                                    reserve, special deposit, compulsory loan or
                                    similar requirement against assets held by,
                                    deposits or other liabilities in or for the
                                    account of, advances, loans or other
                                    extensions of credit by, or any other
                                    acquisition of funds by, any office of such
                                    Lender that is not otherwise included in the
                                    determination of the Eurodollar Rate
                                    hereunder; or

                           (iii)    shall impose on such Lender any other
                                    condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender reasonably deems to be material, of making,
converting into, continuing or

<PAGE>

                                                                              21

maintaining Eurodollar Loans, or to reduce any amount receivable hereunder in
respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender, upon its demand, any additional amounts necessary to compensate such
Lender for such increased cost or reduced amount receivable. If any Lender
becomes entitled to claim any additional amounts pursuant to this Section, it
shall promptly notify the Borrower (with a copy to the Administrative Agent) of
the event by reason of which it has become so entitled.

                  (b)      If any Lender shall have determined that the adoption
of or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such corporation's
policies with respect to capital adequacy) by an amount reasonably deemed by
such Lender to be material, then from time to time, after submission by such
Lender to the Borrower (with a copy to the Administrative Agent) of a written
request therefor, the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or such corporation for such
reduction.

                  (c)      A certificate as to any additional amounts payable
pursuant to this Section submitted by any Lender to the Borrower (with a copy to
the Administrative Agent) shall be conclusive in the absence of manifest error.
The obligations of the Borrower pursuant to this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

                  2.15     Taxes. (a) All payments made by the Borrower under
this Agreement shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Administrative Agent or any Lender
as a result of a present or former connection between the Administrative Agent
or such Lender and the jurisdiction of the Governmental Authority imposing such
tax or any political subdivision or taxing authority thereof or therein (other
than any such connection arising solely from the Administrative Agent's or such
Lender's having executed, delivered or performed its obligations or received a
payment under, or enforced, this Agreement or any other Loan Document). If any
such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") or any Other Taxes are required to be
withheld from any amounts payable to the Administrative Agent or any Lender
hereunder, the amounts so payable to the Administrative Agent or such Lender
shall be increased to the extent necessary to yield to the Administrative Agent
or such Lender (after payment of all Non-Excluded Taxes and Other Taxes)
interest or any such other amounts payable hereunder at the rates or in the
amounts specified in this Agreement; provided, however, that the Borrower shall
not be required to increase any such amounts payable to any Lender with respect
to any Non-Excluded Taxes (i) that are attributable to such Lender's failure to
comply with the requirements of paragraph (d) or (e) of this Section or (ii)
that are United

<PAGE>

                                                                              22

States withholding taxes imposed on amounts payable to such Lender at the time
such Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the Borrower with respect to such Non-Excluded Taxes
pursuant to this paragraph (a).

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

                  (c)      Whenever any Non-Excluded Taxes or Other Taxes are
payable by the Borrower, as promptly as possible thereafter the Borrower shall
send to the Administrative Agent for the account of the relevant Agent or
Lender, as the case may be, a certified copy of an original official receipt
received by the Borrower showing payment thereof. If the Borrower fails to pay
any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other required documentary evidence, the Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure. The agreements in this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

                  (d)      Each Lender (or Transferee) that is not a citizen or
resident of the United States of America, a corporation, partnership or other
entity created or organized in or under the laws of the United States of America
(or any jurisdiction thereof), or any estate or trust that is subject to federal
income taxation regardless of the source of its income (a "Non-U.S. Lender")
shall deliver to the Borrower and the Administrative Agent (or, in the case of a
Participant, to the Lender from which the related participation shall have been
purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or
Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S.
federal withholding tax under Section 871(h) or 881(c) of the Code with respect
to payments of "portfolio interest" a statement substantially in the form of
Exhibit G and a Form W-8BEN, or any subsequent versions thereof or successors
thereto properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on
all payments by the Borrower under this Agreement and the other Loan Documents.
Such forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation). In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the U.S. taxing authorities for such purpose). Notwithstanding any
other provision of this paragraph, a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver.

                  (e)      A Lender that is entitled to an exemption from or
reduction of non-U.S. withholding tax under the law of the jurisdiction in which
the Borrower is located, or any treaty to which such jurisdiction is a party,
with respect to payments under this Agreement shall deliver to the Borrower
(with a copy to the Administrative Agent), at the time or times prescribed by

<PAGE>

                                                                              23

applicable law or reasonably requested by the Borrower, such properly completed
and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate, provided that such
Lender is legally entitled to complete, execute and deliver such documentation
and in such Lender's reasonable judgment such completion, execution or
submission would not materially prejudice the legal position of such Lender.

                  2.16     Indemnity. The Borrower agrees to indemnify each
Lender for, and to hold each Lender harmless from, any loss or expense that such
Lender may sustain or incur as a consequence of (a) default by the Borrower in
making a borrowing of, conversion into or continuation of Eurodollar Loans after
the Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment after the Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a prepayment or conversion of
Eurodollar Loans on a day that is not the last day of an Interest Period with
respect thereto. Such indemnification may include an amount equal to the excess,
if any, of (i) the amount of interest that would have accrued on the amount so
prepaid, or not so borrowed, converted or continued, for the period from the
date of such prepayment or of such failure to borrow, convert or continue to the
last day of such Interest Period (or, in the case of a failure to borrow,
convert or continue, the Interest Period that would have commenced on the date
of such failure) in each case at the applicable rate of interest for such Loans
provided for herein (excluding, however, the Applicable Margin included therein,
if any) over (ii) the amount of interest (as reasonably determined by such
Lender) that would have accrued to such Lender on such amount by placing such
amount on deposit for a comparable period with leading banks in the interbank
Eurodollar market. A certificate as to any amounts payable pursuant to this
Section submitted to the Borrower by any Lender shall be conclusive in the
absence of manifest error. This covenant shall survive the termination of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

                  2.17     Illegality. Notwithstanding any other provision
herein, if the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall
forthwith be canceled and (b) such Lender's Loans then outstanding as Eurodollar
Loans, if any, shall be converted automatically to Base Rate Loans on the
respective last days of the then current Interest Periods with respect to such
Loans or within such earlier period as required by law. If any such conversion
of a Eurodollar Loan occurs on a day which is not the last day of the then
current Interest Period with respect thereto, the Borrower shall pay to such
Lender such amounts, if any, as may be required pursuant to Section 2.16.

                  2.18     Change of Lending Office. Each Lender agrees that,
upon the occurrence of any event giving rise to the operation of Section 2.14,
2.15(a) or 2.17 with respect to such Lender, it will, if requested by the
Borrower, use reasonable efforts (subject to overall policy considerations of
such Lender) to designate another lending office for any Loans affected by such
event with the object of avoiding the consequences of such event; provided, that
such designation is made on terms that, in the sole judgment of such Lender,
cause such Lender and

<PAGE>

                                                                              24

its lending office(s) to suffer no economic, legal or regulatory disadvantage,
and provided, further, that nothing in this Section shall affect or postpone any
of the obligations of any Borrower or the rights of any Lender pursuant to
Section 2.14, 2.15(a) or 2.17.

                  2.19     Replacement of Lenders under Certain Circumstances.
The Borrower shall be permitted to replace any Lender that (a) requests
reimbursement for amounts owing pursuant to Section 2.14 or 2.15 or gives a
notice of illegality pursuant to Section 2.17 or (b) defaults in its obligation
to make Loans hereunder, with a replacement financial institution; provided that
(i) such replacement does not conflict with any Requirement of Law, (ii) no
Event of Default shall have occurred and be continuing at the time of such
replacement, (iii) prior to any such replacement, such Lender shall have taken
no action under Section 2.18 so as to eliminate the continued need for payment
of amounts owing pursuant to Section 2.14 or 2.15 or to eliminate the illegality
referred to in such notice of illegality given pursuant to Section 2.17, (iv)
the replacement financial institution shall purchase, at par, all Loans and
other amounts owing to such replaced Lender on or prior to the date of
replacement, (v) the Borrower shall be liable to such replaced Lender under
Section 2.16 (as though Section 2.16 were applicable) if any Eurodollar Loan
owing to such replaced Lender shall be purchased other than on the last day of
the Interest Period relating thereto, (vi) the replacement financial
institution, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, (vii) the replaced Lender shall be obligated to make such
replacement in accordance with the provisions of Section 9.6 (provided that the
Borrower shall be obligated to pay the registration and processing fee referred
to therein), (viii) the Borrower shall pay all additional amounts (if any)
required pursuant to Section 2.14 or 2.15, as the case may be, in respect of any
period prior to the date on which such replacement shall be consummated, and
(ix) any such replacement shall not be deemed to be a waiver of any rights that
the Borrower, the Administrative Agent or any other Lender shall have against
the replaced Lender.

                   SECTION 3. REPRESENTATIONS AND WARRANTIES

                  To induce the Administrative Agent and the Lenders to enter
into this Agreement and to make the Loans, the Borrower hereby represents and
warrants to the Administrative Agent and each Lender that:

                  3.1      Financial Condition. (a) The audited consolidated
balance sheets of the Borrower as at December 31, 2001 and December 31, 2002 and
the related consolidated statements of income and of cash flows for the fiscal
years ended on such dates, reported on by and accompanied by an unqualified
report from Deloitte & Touche LLP, present fairly the consolidated financial
condition of the Borrower as at such dates, and the consolidated results of its
operations and its consolidated cash flows for the respective fiscal years then
ended. The unaudited consolidated balance sheet of the Borrower as at March 31,
2003, and the related unaudited consolidated statements of income and cash flows
for the 3-month period ended on such date, present fairly the consolidated
financial condition of the Borrower as at such date, and the consolidated
results of its operations and its consolidated cash flows for the 3-month period
then ended (subject to normal year-end audit adjustments). All such financial
statements, including the related schedules and notes thereto, have been
prepared in accordance with GAAP applied consistently throughout the periods
involved (except as approved by the aforementioned firm of accountants and
disclosed therein). The Borrower and its Subsidiaries do not have any

<PAGE>

                                                                              25

material Guarantee Obligations, contingent liabilities and liabilities for
taxes, or any long-term leases or unusual forward or long-term commitments,
including, without limitation, any interest rate or foreign currency swap or
exchange transaction or other obligation in respect of derivatives, that are not
reflected in the most recent financial statements referred to in this paragraph.
During the period from December 31, 2002 to and including the date hereof there
has been no Disposition by the Borrower or any of its Subsidiaries of any
material part of its business or Property.

                  3.2      No Change. Since December 31, 2002, there has been no
development or event that has had or could reasonably be expected to have a
Material Adverse Effect, except as set forth on Schedule 3.2.

                  3.3      Corporate Existence; Compliance with Law. Each of the
Borrower and its Subsidiaries (a) is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, (b) has
the corporate power and authority, and the legal right, to own and operate its
Property, to lease the Property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of Property or the conduct of its business
requires such qualification and (d) is in compliance with all Requirements of
Law except to the extent that the failure to comply therewith could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

                  3.4      Corporate Power; Authorization; Enforceable
Obligations. The Borrower has the corporate power and authority, and the legal
right, to make, deliver and perform the Loan Documents and to borrow hereunder.
The Borrower has taken all necessary corporate action to authorize the
execution, delivery and performance of the Loan Documents and to authorize the
borrowings on the terms and conditions of this Agreement. No consent or
authorization of, filing with, notice to or other act by or in respect of, any
Governmental Authority or any other Person is required in connection with the
borrowings hereunder or the execution, delivery, performance, validity or
enforceability of this Agreement or any of the other Loan Documents, except
consents, authorizations, filings and notices described in Schedule 3.4, which
consents, authorizations, filings and notices have been obtained or made and are
in full force and effect. Each Loan Document has been duly executed and
delivered on behalf of the Borrower. This Agreement constitutes, and each other
Loan Document upon execution will constitute, a legal, valid and binding
obligation of the Borrower, enforceable against the Borrower in accordance with
its terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                  3.5      No Legal Bar. The execution, delivery and
performance of this Agreement and the other Loan Documents, the borrowings
hereunder and the use of the proceeds thereof will not violate any Requirement
of Law or any Contractual Obligation of the Borrower or any of its Subsidiaries
and will not result in, or require, the creation or imposition of any Lien on
any of their respective properties or revenues pursuant to any Requirement of
Law or any such Contractual Obligation (other than the Liens created by the
Security Documents). No Requirement of Law or Contractual Obligation applicable
to the Borrower or any of its
<PAGE>
                                                                              26

Subsidiaries could reasonably be expected to have a Material Adverse Effect.

                  3.6      No Material Litigation. No litigation, investigation
or proceeding of or before any arbitrator or Governmental Authority is pending
or, to the knowledge of the Borrower, threatened by or against the Borrower or
any of its Subsidiaries or against any of their respective properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) that could reasonably be
expected to have a Material Adverse Effect, except as set forth on Schedule 3.6.

                  3.7      No Default. Neither the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect that could reasonably be expected to have a Material
Adverse Effect, except as set forth on Schedule 3.7. No Default or Event of
Default has occurred and is continuing.

                  3.8      Ownership of Property; Liens. Each of the Borrower
and its Subsidiaries has title in fee simple to, or a valid leasehold interest
in, all its real property, and good title to, or a valid leasehold interest in,
all its other Property, and none of such Property is subject to any Lien except
as permitted by Section 6.3.

                  3.9      Intellectual Property. The Borrower and each of its
Subsidiaries owns, or is licensed to use, all Intellectual Property necessary
for the conduct of its business as currently conducted. No material claim has
been asserted and is pending by any Person challenging or questioning the use of
any Intellectual Property or the validity or effectiveness of any Intellectual
Property, nor does the Borrower know of any valid basis for any such claim. The
use of Intellectual Property by the Borrower and its Subsidiaries does not
infringe on the rights of any Person in any material respect.

                  3.10     Taxes. Each of the Borrower and each of its
Subsidiaries has filed or caused to be filed all Federal, state and other
material tax returns that are required to be filed and has paid all taxes shown
to be due and payable on said returns or on any assessments made against it or
any of its Property and all other taxes, fees or other charges imposed on it or
any of its Property by any Governmental Authority (other than any the amount or
validity of which are currently being contested in good faith by appropriate
proceedings and with respect to which reserves in conformity with GAAP have been
provided on the books of the Borrower or its Subsidiaries, as the case may be);
and no tax Lien has been filed, and, to the knowledge of the Borrower, no claim
is being asserted, with respect to any such tax, fee or other charge.

                  3.11     Federal Regulations. No part of the proceeds of any
Loans will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U as now and
from time to time hereafter in effect or for any purpose that violates the
provisions of the Regulations of the Board. If requested by any Lender or the
Administrative Agent, the Borrower will furnish to the Administrative Agent and
each Lender a statement to the foregoing effect in conformity with the
requirements of FR Form G-3 or FR Form U-1 referred to in Regulation U.

                  3.12     Government Approval and Filings. The Public Utilities
Commission of Nevada has duly and validly issued an order authorizing the
Borrower to enter into this

<PAGE>

                                                                              27

Agreement and the other Loan Documents and to take all actions contemplated
hereby or thereby or in connection herewith or therewith, and such order remains
in full force and effect in the form issued. No other authorization, approval,
order, decree, ruling or other action by, or notice to or filing with, any
Governmental Authority is required for the due execution, delivery and
performance by the Borrower of this Agreement or any of the other Loan
Documents.

                  3.13     Labor Matters. There are no strikes or other labor
disputes against the Borrower or any of its Subsidiaries pending or, to the
knowledge of the Borrower, threatened that (individually or in the aggregate)
could reasonably be expected to have a Material Adverse Effect. Hours worked by
and payment made to employees of the Borrower and its Subsidiaries have not been
in violation of the Fair Labor Standards Act or any other applicable Requirement
of Law dealing with such matters that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect. All payments due from
the Borrower or any of its Subsidiaries on account of employee health and
welfare insurance that (individually or in the aggregate) could reasonably be
expected to have a Material Adverse Effect if not paid have been paid or accrued
as a liability on the books of the Borrower or the relevant Subsidiary.

                  3.14     ERISA. Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code. No termination of a Single Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has arisen, during such five-year
period. The present value of all accrued benefits under each Single Employer
Plan (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits by a material amount. Neither the Borrower nor any
Commonly Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan that has resulted or could reasonably be expected to result
in a material liability under ERISA, and neither the Borrower nor any Commonly
Controlled Entity would become subject to any material liability under ERISA if
the Borrower or any such Commonly Controlled Entity were to withdraw completely
from all Multiemployer Plans as of the valuation date most closely preceding the
date on which this representation is made or deemed made. No such Multiemployer
Plan is in Reorganization or Insolvent.

                  3.15     Investment Company Act; Other Regulations. The
Borrower is not an "investment company", or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended. The Borrower is not subject to regulation under any Requirement of
Law (other than Regulation X of the Board) which limits its ability to incur
Indebtedness (other than public utility laws and regulations of Nevada
administered by the Public Utilities Commission of Nevada.

                  3.16     Subsidiaries. (a) The Subsidiaries listed on Schedule
3.16 constitute all the Subsidiaries of the Borrower at the date hereof.
Schedule 3.16 sets forth as of the Closing Date the name and jurisdiction of
incorporation of each Subsidiary and, as to each Subsidiary, the percentage of
each class of Capital Stock owned by the Borrower.

                                                                              28

                  (b)      There are no outstanding subscriptions, options,
warrants, calls, rights or other agreements or commitments of any nature
relating to any Capital Stock of the Borrower or any Subsidiary.

                  3.17     Use of Proceeds. The proceeds of the Loans shall be
used for general corporate purposes.

                  3.18     Environmental Matters. Other than exceptions to any
of the following that could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect:

                  (a)      The Borrower and its Subsidiaries: (i) are, and

current or intended operations or for any property owned, leased, or otherwise

Permits; and (iv) reasonably believe that: each of their Environmental Permits
will be timely renewed and complied with, without material expense; any
additional Environmental Permits that may be required of any of them will be
timely obtained and complied with, without material expense; and compliance with
any Environmental Law that is or is expected to become applicable to any of them
will be timely attained and maintained, without material expense.

                  (b)      Materials of Environmental Concern are present at,
on, under, in, or about any real property now or formerly owned, leased or
operated by the Borrower or any of its Subsidiaries, or at any other location
(including, without limitation, any location to which Materials of Environmental
Concern have been sent for re-use or recycling or for treatment, storage, or
disposal) which could not reasonably be expected, individually or in the
aggregate, to (i) give rise to liability of the Borrower or any of its
Subsidiaries under any applicable Environmental Law or otherwise result in costs
to the Borrower or any of its Subsidiaries which could reasonably be expected to
have a Material Adverse Effect, or (ii) interfere with the Borrower's or any of
its Subsidiaries' continued operations, or (iii) materially adversely affect the
fair saleable value of any real property owned or leased by the Borrower or any
of its Subsidiaries.

                  (c)      There is no judicial, administrative, or arbitral
proceeding (including any notice of violation or alleged violation) under or
relating to any Environmental Law to which the Borrower or any of its
Subsidiaries is, or to the knowledge of the Borrower or any of its Subsidiaries
will be, named as a party that is pending or, to the knowledge of the Borrower
or any of its Subsidiaries, threatened.

                  (d)      Neither the Borrower nor any of its Subsidiaries has
received any written request for information, or been notified that it is a
potentially responsible party under or relating to the federal Comprehensive
Environmental Response, Compensation, and Liability Act or any similar
Environmental Law, or with respect to any Materials of Environmental Concern.

                  (e)      Neither the Borrower nor any of its Subsidiaries has
entered into or agreed

<PAGE>

                                                                              29

to any consent decree, order, or settlement or other agreement, or is subject to
any judgment, decree, or order or other agreement, in any judicial,
administrative, arbitral, or other forum for dispute resolution, relating to
compliance with or liability under any Environmental Law.

                  (f)      Neither the Borrower nor any of its Subsidiaries has
assumed or retained, by contract or operation of law, any liabilities of any
kind, fixed or contingent, known or unknown, under any Environmental Law or with
respect to any Material of Environmental Concern.

                  3.19     Accuracy of Information, etc. No statement or
information contained in this Agreement, any other Loan Document or any other
document, certificate or statement furnished to the Administrative Agent or the
Lenders or any of them, by or on behalf of the Borrower for use in connection
with the transactions contemplated by this Agreement or the other Loan
Documents, contained as of the date such statement, information, document or
certificate was so furnished, any untrue statement of a material fact or omitted
to state a material fact necessary in order to make the statements contained
herein or therein not misleading. The projections and pro forma financial
information contained in the materials referenced above are based upon good
faith estimates and assumptions believed by management of the Borrower to be
reasonable at the time made, it being recognized by the Lenders that such
financial information as it relates to future events is not to be viewed as fact
and that actual results during the period or periods covered by such financial
information may differ from the projected results set forth therein by a
material amount. There is no fact known to the Borrower that could reasonably be
expected to have a Material Adverse Effect that has not been expressly disclosed
herein, in the other Loan Documents or in any other documents, certificates and
statements furnished to the Administrative Agent and the Lenders for use in
connection with the transactions contemplated hereby and by the other Loan
Documents.

                  3.20     Bond Delivery Agreement; G&R Series F Mortgage Bond.

                  (a)      The Bond Delivery Agreement is effective to create in
favor of the Administrative Agent, for the benefit of the Lenders, a legal,
valid and enforceable security interest in any right, title and interest of the
Borrower in the G&R Series F Mortgage Bond and proceeds thereof, and, when
perfected by delivery of the G&R Series F Mortgage Bond to the Administrative
Agent for the benefit of the Lenders, the Lien granted pursuant to the Bond
Delivery Agreement shall constitute a fully perfected Lien on, and security
interest in, all right, title and interest, if any, of the Borrower in such G&R
Series F Mortgage Bond and the proceeds thereof, as security for the
Obligations, in each case prior and superior in right to any other Person.

General and Refunding Mortgage Indenture); and constitutes collateral security
for the obligations of the Borrower as purported to be provided in

similar business.

Default, with the consent of the Required Lenders, the Administrative Agent may,
or upon the request of the Required Lenders, the Administrative Agent shall, by
notice to the Borrower, declare the Loans hereunder (with accrued interest
thereon) and all other amounts owing under this Agreement and the other Loan
Documents to be due and payable forthwith, whereupon the same shall immediately
become due and payable.

                      SECTION 8. THE ADMINISTRATIVE AGENT

                  8.1      Appointment. Each Lender hereby irrevocably
designates and appoints the Administrative Agent as the agent of such Lender
under this Agreement and the other Loan Documents, and each Lender irrevocably
authorizes the Administrative Agent, in such capacity, to take such action on
its behalf under the provisions of this Agreement and the other Loan Documents
and to exercise such powers and perform such duties as are expressly delegated
to the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

                  8.2      Delegation of Duties. The Administrative Agent may
execute any of its duties under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to

<PAGE>

                                                                              43

such duties. The Administrative Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

                  8.3      Exculpatory Provisions. Neither any Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or affiliates
shall be (i) liable for any action lawfully taken or omitted to be taken by it
or such Person under or in connection with this Agreement or any other Loan
Document (except to the extent that any of the foregoing are found by a final
and nonappealable decision of a court of competent jurisdiction to have resulted
from its or such Person's own gross negligence or willful misconduct) or (ii)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by the Borrower or any officer thereof
contained in this Agreement or any other Loan Document or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Administrative Agent under or in connection with, this Agreement or any
other Loan Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document or
for any failure of the Borrower to perform its obligations hereunder or
thereunder. The Administrative Agent shall not be under any obligation to any
Lender to ascertain or to inquire as to the observance or performance of any of
the agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower.

                  8.4      Reliance by the Administrative Agent. The
Administrative Agent shall be entitled to rely, and shall be fully protected in
relying, upon any instrument, writing, resolution, notice, consent, certificate,
affidavit, letter, telecopy, telex or teletype message, statement, order or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Borrower), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of
any Revolving Credit Note as the owner thereof for all purposes unless such
Revolving Credit Note shall have been transferred in accordance with Section 9.6
and all actions required by such Section in connection with such transfer shall
have been taken. The Administrative Agent shall be fully justified in failing or
refusing to take any action under this Agreement or any other Loan Document
unless it shall first receive such advice or concurrence of the Required Lenders
(or, if so specified by this Agreement, all Lenders or any other instructing
group of Lenders specified by this Agreement) as it deems appropriate or it
shall first be indemnified to its satisfaction by the Lenders against any and
all liability and expense that may be incurred by it by reason of taking or
continuing to take any such action. Each Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement and the
other Loan Documents in accordance with a request of the Required Lenders (or,
if so specified by this Agreement, all Lenders or any other instructing group of
Lenders specified by this Agreement), and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

                  8.5      Notice of Default. The Administrative Agent shall not
be deemed to have knowledge or notice of the occurrence of any Default or Event
of Default hereunder unless the Administrative Agent shall have received notice
from a Lender or the Borrower referring to this Agreement, describing such
Default or Event of Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent shall receive such a
notice, the

<PAGE>

                                                                              44

Administrative Agent shall give notice thereof to the Lenders. The
Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Required Lenders (or, if
so specified by this Agreement, all Lenders or any other instructing group of
Lenders specified by this Agreement); provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Lenders.

                  8.6      Non-Reliance on Administrative Agent and Other
Lenders. Each Lender expressly acknowledges that neither any of the
Administrative Agent nor any of their respective officers, directors, employees,
agents, attorneys-in-fact or affiliates have made any representations or
warranties to it and that no act by any Agent hereafter taken, including any
review of the affairs of the Borrower or any affiliate of the Borrower, shall be
deemed to constitute any representation or warranty by any Agent to any Lender.
Each Lender represents to the Administrative Agent 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 appraisal
of and investigation into the business, operations, property, financial and
other condition and creditworthiness of the Borrower and its affiliates and made
its own decision to make its Loans hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon any
Agent or any other Lender, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigation as it deems necessary
to inform itself as to the business, operations, property, financial and other
condition and creditworthiness of the Borrower and its affiliates. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Administrative Agent hereunder, no Agent shall have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Borrower or any affiliate of
the Borrower that may come into the possession of such Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates.

                  8.7      Indemnification. The Lenders agree to indemnify each
Agent in its capacity as such (to the extent not reimbursed by the Borrower and
without limiting the obligation of the Borrower to do so), ratably according to
their respective Aggregate Exposure Percentages in effect on the date on which
indemnification is sought under this Section (or, if indemnification is sought
after the date upon which the Commitments shall have terminated and the Loans
shall have been paid in full, ratably in accordance with such Aggregate Exposure
Percentages immediately prior to such date), for, and to save each Agent
harmless from and against, any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever that may at any time (including, without limitation, at
any time following the payment of the Loans) be imposed on, incurred by or
asserted against such Agent in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by such Agent
under or in connection with any of the foregoing; provided that no Lender shall
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements that are found by a final

<PAGE>

                                                                              45

and nonappealable decision of a court of competent jurisdiction to have resulted
from such Agent's gross negligence or willful misconduct. The agreements in this
Section shall survive the payment of the Loans and all other amounts payable
hereunder.

                  8.8      Agent in Its Individual Capacity. Each Agent and its
affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrower as though such Agent were not an Agent. With
respect to its Loans made or renewed by it and with respect to any Letter of
Credit issued or participated in by it, each Agent shall have the same rights
and powers under this Agreement and the other Loan Documents as any Lender and
may exercise the same as though it were not an Agent, and the terms "Lender" and
"Lenders" shall include each Agent in its individual capacity.

                  8.9      Successor Administrative Agent. The Administrative
Agent may resign as Administrative Agent upon 10 days' notice to the Lenders and
the Borrower. If the Administrative Agent shall resign as Administrative Agent
under this Agreement and the other Loan Documents, then the Required Lenders
shall appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall (unless an Event of Default under Section 8(a) or Section
8(f) with respect to the Borrower shall have occurred and be continuing) be
subject to approval by the Borrower (which approval shall not be unreasonably
withheld or delayed), whereupon such successor agent shall succeed to the
rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Loans. If no successor agent
has accepted appointment as Administrative Agent by the date that is 10 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become
effective, and the Lenders shall assume and perform all of the duties of the
Administrative Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above. After any retiring Agent's
resignation as Agent, the provisions of this Section 8 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement and the other Loan Documents.

                  8.10     The Arranger. The Arranger, in its capacity as such,
shall not have any duties or responsibilities, and shall incur no liability,
under this Agreement and the other Loan Documents.

                            SECTION 9. MISCELLANEOUS

                  9.1      Amendments and Waivers. Neither this Agreement or any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
Section 9.1. The Required Lenders and the Borrower may, or (with the written
consent of the Required Lenders) the Administrative Agent and the Borrower may,
from time to time, (a) enter into written amendments, supplements or
modifications hereto and to the other Loan Documents (including amendments and
restatements hereof or thereof) for the purpose of adding any provisions to this
Agreement or the other Loan Documents or changing in any manner the rights of
the Lenders or of the Borrower hereunder or

                                                                              46

thereunder or (b) waive, on such terms and conditions as may be specified in the
instrument of waiver, any of the requirements of this Agreement or the other
Loan Documents or any Default or Event of Default and its consequences;
provided, however, that no such waiver and no such amendment, supplement or
modification shall:

                           (i)      forgive the principal amount or extend the
                                    final scheduled date of maturity of any
                                    Loan, extend the scheduled date of any
                                    amortization payment in respect of any Loan,
                                    reduce the stated rate of any interest or
                                    fee payable hereunder or extend the
                                    scheduled date of any payment thereof, or
                                    increase the amount or extend the expiration
                                    date of any Commitment of any Lender, in
                                    each case without the consent of each Lender
                                    directly affected thereby;

                           (ii)     amend, modify or waive any provision of this
                                    Section or reduce any percentage specified
                                    in the definition of Required Lenders,
                                    consent to the assignment or transfer by the
                                    Borrower of any of its rights and
                                    obligations under this Agreement and the
                                    other Loan Documents or release the G&R
                                    Series F Mortgage Bond, in whole or in part,
                                    each case without the consent of all
                                    Lenders;

                           (iii)    amend, modify or waive any provision of
                                    Section 8 or any other provision affecting
                                    the rights of any Agent without the consent
                                    of any Agent directly affected thereby; or

                           (iv)     amend, modify or waive any provision of
                                    Section 2.13 without the consent of each
                                    Lender directly affected thereby.

Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Borrower, the
Lenders, the Administrative Agent and all future holders of the Loans. In the
case of any waiver, the Borrower, the Lenders and the Administrative Agent shall
be restored to their former position and rights hereunder and under the other
Loan Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default, or impair any right consequent thereon. Any
such waiver, amendment, supplement or modification shall be effected by a
written instrument signed by the parties required to sign pursuant to the
foregoing provisions of this Section; provided, that delivery of an executed
signature page of any such instrument by facsimile transmission shall be
effective as delivery of a manually executed counterpart thereof. The
Administrative Agent, as holder of the G&R Series F Mortgage Bond, will not
consent to any amendment or other modification of the General and Refunding
Mortgage Indenture that requires the consent of holders of all securities issued
thereunder, without the consent of each Lender.

                  9.2      Notices. All notices, requests and demands to or upon
the respective parties hereto to be effective shall be in writing (including by

right, remedy, power or privilege hereunder or under the other Loan Documents

with the execution and delivery of, or consummation or administration of any of
the transactions contemplated by, or any amendment, the G&R Series F Mortgage
Bond, supplement or modification of, or any waiver or consent under or in
respect of, this Agreement, the G&R Series F Mortgage Bond, the other Loan

officers, directors, trustees, employees, advisors, agents and controlling

performance and administration of this Agreement, the G&R Series F Mortgage
Bond, the other Loan Documents and any such other documents, including, without
limitation, any of the foregoing relating to the use of proceeds of the Loans or
the violation of, noncompliance with or liability under, any Environmental Law
applicable to the operations of the Borrower any of its Subsidiaries or any of
the Properties and the fees and disbursements and other charges of legal counsel
in connection with claims, actions or proceedings by any Indemnitee against the
Borrower hereunder (all the foregoing in this clause (d), collectively, the
"Indemnified Liabilities"), provided, that the Borrower shall have no obligation
hereunder to any Indemnitee with respect to Indemnified Liabilities to the
extent such Indemnified Liabilities are found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of such Indemnitee. No Indemnitee shall be
liable for any damages arising from the use by unauthorized persons of
Information or other materials sent through electronic, telecommunications or
other information transmission systems that are intercepted by such persons or
for any special, indirect, consequential or punitive damages in connection with
this Agreement. Without limiting the foregoing, and to the extent permitted by
applicable law, the Borrower agrees not to assert and to cause its Subsidiaries
not to assert, and hereby waives and agrees to cause its Subsidiaries so to
waive, all rights for contribution or any other rights of recovery with respect
to all claims, demands, penalties, fines, liabilities, settlements, damages,
costs and expenses of whatever kind or nature, under or related to Environmental
Laws, that any of them might have by statute or otherwise against any
Indemnitee. All amounts due under this Section shall be payable not later than
30 days after written demand therefor. Statements payable by the Borrower

                  9.6      Successors and Assigns; Participations and
Assignments. (a) This Agreement shall be binding upon and inure to the benefit
of the Borrower, the Lenders, the Administrative Agent, all future holders of
the Loans and their respective successors and assigns, except that the Borrower
may not assign or transfer any of its rights or obligations under this Agreement
without the prior written consent of the Administrative Agent and each Lender.

                                                                              49

                  (b)      Any Lender may, without the consent of the Borrower,
in accordance with applicable law, at any time sell to one or more banks,
financial institutions or other entities (each, a "Participant") participating
interests in any Loan owing to such Lender, any Commitment of such Lender or any
other interest of such Lender hereunder and under the other Loan Documents. In
the event of any such sale by a Lender of a participating interest to a
Participant, such Lender's obligations under this Agreement to the other parties
to this Agreement shall remain unchanged, such Lender shall remain solely
responsible for the performance thereof, such Lender shall remain the holder of
any such Loan for all purposes under this Agreement and the other Loan
Documents, and the Borrower and the Administrative Agent shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents. In no event shall
any Participant under any such participation have any right to approve any
amendment or waiver of any provision of any Loan Document, or any consent to any
departure by the Borrower therefrom, except to the extent that such amendment,
waiver or consent would require the consent of all Lenders pursuant to Section
9.1. The Borrower agrees that if amounts outstanding under this Agreement and
the Loans are due or unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall, to the maximum extent permitted by applicable law, be deemed to have the
right of setoff in respect of its participating interest in amounts owing under
this Agreement to the same extent as if the amount of its participating interest
were owing directly to it as a Lender under this Agreement, provided that, in
purchasing such participating interest, such Participant shall be deemed to have
agreed to share with the Lenders the proceeds thereof as provided in Section
9.7(a) as fully as if such Participant were a Lender hereunder. The Borrower
also agrees that each Participant shall be entitled to the benefits of Sections
2.14, 2.15 and 2.16 with respect to its participation in the Commitments and the
Loans outstanding from time to time as if such Participant were a Lender;
provided that, in the case of Section 2.15, such Participant shall have complied
with the requirements of said Section, and provided, further, that no
Participant shall be entitled to receive any greater amount pursuant to any such
Section than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred by such transferor Lender
to such Participant had no such transfer occurred.

                  (c)      Any Lender (an "Assignor") may, in accordance with
applicable law and upon written notice to the Administrative Agent, at any time
and from time to time assign to any Lender or any affiliate, Related Fund or
Control Investment Affiliate thereof or, with the consent of the Administrative
Agent (which, in each case, shall not be unreasonably withheld or delayed), to
an additional bank, financial institution or other entity (an "Assignee") all or
any part of its rights and obligations under this Agreement pursuant to an
Assignment and Acceptance, substantially in the form of Exhibit D, executed by
such Assignee and such Assignor (and, where the consent of the Administrative
Agent is required pursuant to the foregoing provisions, by the Administrative
Agent) and delivered to the Administrative Agent for its acceptance and
recording in the Register; provided that no such assignment to an Assignee
(other than any Lender or any affiliate thereof or any Related Fund) shall be in
an aggregate principal amount of less than $1,000,000 (other than in the case of
an assignment of all of a Lender's interests under this Agreement), unless
otherwise agreed by the Borrower and the Administrative Agent. Upon such
execution, delivery, acceptance and recording, from and after the effective date
determined pursuant to such Assignment and Acceptance, (x) the Assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and

<PAGE>

                                                                              50

Acceptance, have the rights and obligations of a Lender hereunder with
Commitments and/or Loans as set forth therein, and (y) the Assignor thereunder
shall, to the extent provided in such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of an Assignor's rights and obligations under this
Agreement, such Assignor shall cease to be a party hereto, except as to Section
2.14, 2.15 and 9.5 in respect of the period prior to such effective date). For
purposes of the minimum assignment amounts set forth in this paragraph, multiple
assignments by two or more Related Funds shall be aggregated.

                  (d)      The Administrative Agent shall, on behalf of the
Borrower, maintain at its address referred to in Section 9.2 a copy of each
Assignment and Acceptance delivered to it and a register (the "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 from time to time. The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, each Agent and the Lenders shall treat each Person whose name
is recorded in the Register as the owner of the Loans and any Revolving Credit
Notes evidencing such Loans recorded therein for all purposes of this Agreement.
Any assignment of any Loan, whether or not evidenced by a Revolving Credit Note,
shall be effective only upon appropriate entries with respect thereto being made
in the Register (and each Revolving Credit Note shall expressly so provide). Any
assignment or transfer of all or part of a Loan evidenced by a Revolving Credit
Note shall be registered on the Register only upon surrender for registration of
assignment or transfer of the Revolving Credit Note evidencing such Loan,
accompanied by a duly executed Assignment and Acceptance; thereupon one or more
new Revolving Credit Notes in the same aggregate principal amount shall be
issued to the designated Assignee, and the old Revolving Credit Notes shall be
returned by the Administrative Agent to the Borrower marked "canceled". The
Register shall be available for inspection by the Borrower or any Lender (with
respect to any entry relating to such Lender's Loans) at any reasonable time and
from time to time upon reasonable prior notice.

                  (e)      Upon its receipt of an Assignment and Acceptance
executed by an Assignor and an Assignee (and, in any case where the consent of
any other Person is required by Section 9.6(c), by each such other Person)
together with payment to the Administrative Agent of a registration and
processing fee of $3,500 (payable by the Assignor or Assignee, as agreed between
such parties) (treating multiple, simultaneous assignments by two or more
Related Funds as a single assignment) (except that no such registration and
processing fee shall be payable (y) in connection with an assignment by or to a
Merrill Lynch Entity or (z) in the case of an Assignee which is already a Lender
or is an affiliate or Related Fund of a Lender or a Person under common
management with a Lender), the Administrative Agent shall (i) promptly accept
such 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 applicable
Revolving Credit Notes, of the assigning Lender) a new applicable Revolving
Credit Note to the order of such Assignee in an amount equal to the applicable
Loans, assumed or acquired by it pursuant to such Assignment and Acceptance and,
if the Assignor has retained a Loan, as the case may be, upon request, a new
Revolving Credit Note, to the order of the Assignor in an amount equal to the
applicable Loan, as the case may be, retained by it hereunder.

                                                                              51

Such new Revolving Credit Note or Revolving Credit Notes shall be dated the
Closing Date and shall otherwise be in the form of the Revolving Credit Note or
Revolving Credit Notes replaced thereby.

                  (f)      For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this Section concerning assignments of Loans
and Revolving Credit Notes relate only to absolute assignments and that such
provisions do not prohibit assignments creating security interests in Loans and
Revolving Credit Notes, including, without limitation, any pledge or assignment
by a Lender of any Loan or Revolving Credit Note to any Federal Reserve Bank in
accordance with applicable law.

                  (g)      Notwithstanding anything to the contrary contained
herein, any Lender (a "Granting Lender") may grant to a special purpose funding
vehicle (an "SPC"), identified as such in writing from time to time by the
Granting Lender to the Administrative Agent and the Borrower, the option to
provide to the Borrower all or any part of any Loan that such Granting Lender
would otherwise be obligated to make to the Borrower pursuant to this Agreement;
provided that (i) nothing herein shall constitute a commitment by any SPC to
make any Loan and (ii) if an SPC elects not to exercise such option or otherwise
fails to provide all or any part of such Loan, the Granting Lender shall be
obligated to make such Loan pursuant to the terms hereof. The making of a Loan
by an SPC hereunder shall utilize the Commitment of the Granting Lender to the
same extent, and as if, such Loan were made by such Granting Lender. Each party
hereto hereby agrees that no SPC shall be liable for any indemnity or similar
payment obligation under this Agreement (all liability for which shall remain
with the Granting Lender). In furtherance of the foregoing, each party hereto
hereby agrees (which agreement shall survive the termination of this Agreement)
that, prior to the date that is one year and one day after the payment in full
of all outstanding commercial paper or other indebtedness of any SPC, it will
not institute against, or join any other person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any state thereof. In
addition, notwithstanding anything to the contrary in this Section 9.6(g), any
SPC may (A) with notice to, but without the prior written consent of, the
Borrower and the Administrative Agent and without paying any processing fee
therefor, assign all or a portion of its interests in any Loans to the Granting
Lender, or with the prior written consent of the Borrower and the Administrative
Agent (which consent shall not be unreasonably withheld) to any financial
institutions providing liquidity and/or credit support to or for the account of
such SPC to support the funding or maintenance of Loans, and (B) disclose on a
confidential basis any non-public information relating to its Loans to any
rating agency, commercial paper dealer or provider of any surety, guarantee or
credit or liquidity enhancement to such SPC; provided that non-public
information with respect to the Borrower may be disclosed only with the
Borrower's consent which will not be unreasonably withheld. This paragraph (g)
may not be amended without the written consent of any SPC with Loans outstanding
at the time of such proposed amendment.

                  9.7      Adjustments; Set-off. (a) If any Lender (a
"Benefitted Lender") shall at any time receive any payment of all or part of the
Obligations owing to it, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, pursuant to events or proceedings of
the nature referred to in Section 7(f), or otherwise), in a greater proportion
than any such payment to or collateral received by any other Lender, if any, in
respect of such other

<PAGE>

                                                                              52

Lender's Obligations, such Benefitted Lender shall purchase for cash from the
other Lenders a participating interest in such portion of each such other
Lender's Obligations, or shall provide such other Lenders with the benefits of
any such collateral, as shall be necessary to cause such Benefitted Lender to
share the excess payment or benefits of such collateral ratably with each of the
Lenders; provided, however, that if all or any portion of such excess payment or
benefits is thereafter recovered from such Benefitted Lender, such purchase
shall be rescinded, and the purchase price and benefits returned, to the extent
of such recovery, but without interest.

                  (b)      In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to or
the Borrower, any such notice being expressly waived by the Borrower to the
extent permitted by applicable law, upon any amount becoming due and payable by
the Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise), to set off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of the Borrower. Each Lender agrees
promptly to notify the Borrower and the Administrative Agent after any such
setoff and application made by such Lender, provided that the failure to give
such notice shall not affect the validity of such setoff and application.

                  9.8      Counterparts. This Agreement may be executed by one
or more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument. Delivery of an executed signature page of this
Agreement by facsimile transmission shall be effective as delivery of a manually
executed counterpart hereof. A set of the copies of this Agreement signed by all
the parties shall be lodged with the Borrower and the Administrative Agent.

                  9.9      Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  9.10     Integration. This Agreement and the other Loan
Documents represent the entire agreement of the Borrower, the Administrative
Agent, the Arranger and the Lenders with respect to the subject matter hereof
and thereof, and there are no promises, undertakings, representations or
warranties by the Arranger, any Agent or any Lender relative to subject matter
hereof not expressly set forth or referred to herein or in the other Loan
Documents.

                  9.11     GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  9.12     Submission To Jurisdiction; Waivers. The Borrower
hereby irrevocably and unconditionally:

<PAGE>

                                                                              53

                  (a)      submits for itself and its Property in any legal
action or proceeding relating to this Agreement and the other Loan Documents to
which it is a party, or for recognition and enforcement of any judgment in
respect thereof, to the non-exclusive general jurisdiction of the courts of the
State of New York, the courts of the United States of America for the Southern
District of New York, and appellate courts from any thereof;

                  (b)      consents that any such action or proceeding may be
brought in such courts and waives any objection that it may now or hereafter
have to the venue of any such action or proceeding in any such court or that
such action or proceeding was brought in an inconvenient court and agrees not to
plead or claim the same;

                  (c)      agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Borrower at its address set forth in Section 9.2 or at such other address of
which the Administrative Agent shall have been notified pursuant thereto;

                  (d)      agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction; and

                  (e)      waives, to the maximum extent not prohibited by law,
any right it may have to claim or recover in any legal action or proceeding
referred to in this Section any special, exemplary, punitive or consequential
damages.

                  9.13     Acknowledgments. The Borrower hereby acknowledges
that:

                  (a)      it has been advised by counsel in the negotiation,
execution and delivery of this Agreement and the other Loan Documents;

                  (b)      neither the Arranger, any Agent nor any Lender has
any fiduciary relationship with or duty to the Borrower arising out of or in
connection with this Agreement or any of the other Loan Documents, and the
relationship between the Arranger, the Administrative Agent and the Lenders, on
one hand, and the Borrower, on the other hand, in connection herewith or
therewith is solely that of debtor and creditor; and

                  (c)      no joint venture is created hereby or by the other
Loan Documents or otherwise exists by virtue of the transactions contemplated
hereby among the Arranger, the Administrative Agent and the Lenders or among the
Borrower and the Lenders.

                  9.14     Confidentiality. Each of the Administrative Agent and
the Lenders agrees to keep confidential all non-public information provided to
it by the Borrower pursuant to this Agreement that is designated by the Borrower
as confidential; provided that nothing herein shall prevent any Agent or any
Lender from disclosing any such information (a) to the Arranger, any Agent, any
other Lender or any affiliate of any thereof, (b) to any Participant or Assignee
(each, a "Transferee") or prospective Transferee that agrees to comply with the
provisions of this Section or substantially equivalent provisions, (c) to any of
its employees, directors, Administrative Agent, attorneys, accountants and other
professional advisors, (d) to any financial institution that is a direct or
indirect contractual counterparty in swap agreements or such contractual
counterparty's professional advisor (so long as such contractual counterparty or

<PAGE>

                                                                              54

professional advisor to such contractual counterparty agrees to be bound by the
provisions of this Section), (e) upon the request or demand of any Governmental
Authority having jurisdiction over it, (f) in response to any order of any court
or other Governmental Authority or as may otherwise be required pursuant to any
Requirement of Law, (g) in connection with any litigation or similar proceeding,
(h) that has been publicly disclosed other than in breach of this Section, (i)
to the National Association of Insurance Commissioners or any similar
organization or any nationally recognized rating agency that requires access to
information about a Lender's investment portfolio in connection with ratings
issued with respect to such Lender or (j) in connection with the exercise of any
remedy hereunder or under any other Loan Document. Notwithstanding anything
herein to the contrary, any party to this Agreement (and any employee,
representative, or other agent of any party to this Agreement) may disclose to
any and all persons, without limitation of any kind, the tax treatment and tax
structure of the transactions contemplated by this Agreement and all materials
of any kind (including opinions or other tax analyses) that are provided to it
relating to such tax treatment and tax structure. However, any such information
relating to the tax treatment or tax structure is required to be kept
confidential to the extent necessary to comply with any applicable federal or
state securities laws.

                  9.15     Accounting Changes. In the event that any "Accounting
Change" (as defined below) shall occur and such change results in a change in
the method of calculation of financial covenants, standards or terms in this
Agreement, then the Borrower and the Administrative Agent agree to enter into
negotiations in order to amend such provisions of this Agreement so as to
equitably reflect such Accounting Change with the desired result that the
criteria for evaluating the Borrower's financial condition shall be the same
after such Accounting Change as if such Accounting Change had not been made.
Until such time as such an amendment shall have been executed and delivered by
the Borrower, the Administrative Agent and the Required Lenders, all financial
covenants, standards and terms in this Agreement shall continue to be calculated
or construed as if such Accounting Change had not occurred. "Accounting Change"
refers to any change in accounting principles required by the promulgation of
any rule, regulation, pronouncement or opinion by the Financial Accounting
Standards Board of the American Institute of Certified Public Accountants or, if
applicable, the SEC.

                  9.16     WAIVERS OF JURY TRIAL. THE BORROWER, THE
ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.
