May 22, 2002 -- AMENDED AGREEMENT

Mr. John F. Young
4505 Dudley Lane
Atlanta GA 30327

Dear John,

On behalf of the Board of Directors, I am pleased to offer you employment as
Senior Vice President Energy Supply for Sierra Pacific Resources for a period of
one (1) year. At the end of one (1) year, by mutual agreement, either this
contract may be extended for an additional period or you may become a regular
full time employee of the company. Your primary work location will be Las Vegas,
Nevada. The job does require business travel especially between Las Vegas and
Reno. We expect that you will assume your duties as soon as possible.

Your starting base salary in this position will be $275,000. You will also be
eligible for an annual cash incentive (STIP) of 45% of your base salary. Payment
of the Short Term Incentive is at the discretion of the Board of Directors and
is based on corporate, business unit and personal performance. Actual payout may
vary from 0% to 150% of target. Your participation for 2002 will be prorated
from your start date.

Long-term incentives for this position are in accordance with the plan approved
by the shareholders and administered by the Board of Directors. At this time,
long-term incentives consist of Non-Qualified Stock Options (NQSO's) and
performance shares. For your position the long-term incentive is targeted at 75%
of your base salary, 60% delivered through NQSO's and 40% delivered through
Performance Shares. The NQSO's vest one-third per year and are fully vested
after the third year. Performance shares have a three-year term and are earned
based on measures established by the Board for each grant. You will also be
eligible to participate on a pro-rata basis (31 of 36 months) in the 2002-2004
Performance Share grant made earlier this year. In addition you will also be
able to participate in the 2001-2003 Performance Share grant for the remaining
19 of the original 36 months.

As a special inducement for you to join SPR, the Board has also authorized the
following incentives. A one-time signing bonus of $35,000, gross amount before
taxes. In addition, you will receive a special stock option grant of 25,000
NQSO's at a strike price to be set based on the closing stock price on the day
you accept this offer by signing it and informing me that you have done so.
These options will vest at the end of one year, or upon change of control if
such an event were to occur before the end of one year, or if you are released
from employment for other than the reasons described below. Should you become a
regular employee as a Senior Vice President, you will be expected to achieve and
maintain one and a half times your annual compensation in SPR stock. You will
have five years to achieve this level.

You will be eligible to participate in the Company's Supplemental Executive
Retirement Plan (SERP) and eligible for benefits under this Plan including a
maximum benefit of 50% of your Final Average Earnings.

The Company will also provide you life insurance coverage of $400,000 contingent
upon completion of a physical exam performed by a doctor selected by our
insurance carrier. This will be in addition to a $1,000,000 policy in the event
that you die while traveling on Company business and company provided group life
insurance equivalent to 1.5 of your annual salary.

You will be eligible for all regular employee benefits including a 401K plan
that matches employee contributions dollar for dollar up to 6% and SPR's
Deferred Compensation Plan. You will receive a perquisite allowance of $9,100 to
cover such expenses as a car, tax preparation and club memberships. You will
receive paid time off (PTO) based on your total years of professional work
experience (27). Your annual paid time off allowance will be 43 days, which
include 11 paid holidays. In 2002, it will be pro rated based on your hire date.

In addition to the benefits described above, in the event you are terminated for
reasons other than (1) reasons relating to moral turpitude, (2) conviction of
any crime amounting to a felony, or (3) on your own volition and without
actually being requested to resign by the Board, you will receive within thirty
days of termination, one year of base salary. This payment shall be conditioned
on the execution of appropriate releases in favor of the Company for any and all
claims connected with or arising out of your employment or termination and will
require continued maintenance of confidential and proprietary information, a
non-compete for one year and agreement not to disparage the Company.

This offer includes reimbursement for reasonable relocation expenses including
travel to/from your current home, packing and transportation of your household
goods, expenses related to acquisition of a new home in Las Vegas and commission
on the sale of your current home. You will be allowed to delay your relocation
for up to one year from the date of conversion to regular employee.

The Company will pay for your reasonable travel expenses to make visits home
during this period. The Company will provide temporary apartment housing in Las
Vegas until your permanent relocation takes place.

As is Sierra's policy, all hiring offers are contingent on a drug analysis test.
We can arrange for you to have this test at a time and place convenient for you.
Also you will need to provide us proof of U.S. Citizenship on your first day of
work. This could include a copy of your Birth Certificate, Driver's License or
Social Security Card.

The position being offered to you is one of trust and confidence. In accepting
the position you are agreeing that, in addition to any other limitation and
regardless of the circumstances or any future limitation of your employment, you
will not communicate to any person, firm or other entity any knowledge relating
to documents, transactions or any other confidential knowledge which you might
acquire with respect to the business of Sierra Pacific Resources or any of its
affiliated companies.

shareholders, customers, employees and communities. Welcome!

of such prepayment and (ii) if such prepayment is made on or after the first
anniversary of the Closing Date and prior to the second anniversary of the
Closing Date, 1% of the principal amount of such prepayment.

                  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 Loans shall be prepaid by
an amount equal to the amount of the Net Cash Proceeds of such incurrence. The
provisions of the paragraph do not constitute a consent to the incurrence of any
Indebtedness not permitted by Section 6.2.

                                                                              19

                  (b) If any Capital Stock shall be issued by the Borrower
(excluding any Capital Stock issued to Resources and any capital contributions
received by the Borrower from Resources), then, on the date of such issuance,
the Loans shall be prepaid by an amount equal to 50% of the amount of the Net
Cash Proceeds of such issuance. The provisions of the paragraph do not
constitute a consent to any Change of Control.

                  (c) If, on any date the Borrower or any of its Subsidiaries
shall receive Net Cash Proceeds from any Asset Sale or Recovery Event, then,
unless a Reinvestment Notice shall be delivered in respect thereof, on the date
of receipt by the Borrower or any of its Subsidiaries of such Net Cash Proceeds,
the Loans shall be prepaid by an amount equal to the amount of such Net Cash
Proceeds; provided, that, notwithstanding the foregoing, (i) the aggregate Net
Cash Proceeds of Asset Sales that may be excluded from the foregoing requirement
pursuant to a Reinvestment Notice shall not exceed $5,000,000 in any fiscal year
of the Borrower and (ii) on each Reinvestment Prepayment Date the Loans shall be
prepaid by an amount equal to the Reinvestment Prepayment Amount with respect to
the relevant Reinvestment Event. The provisions of this paragraph do not
constitute a consent to the consummation of any Disposition not permitted by
Section 6.5.

                  (d) 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 three 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
<PAGE>
                                                                              20

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.

                  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 in effect for such day.

                  (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 in effect for such day.

                  (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.
<PAGE>
                                                                              21

                  (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 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. The amount of each principal prepayment of the Loans shall be
applied to reduce the then remaining installments of the Loans pro rata based
upon the then remaining principal amount thereof. Amounts prepaid on account of
the Loans may not be reborrowed.

                  (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
<PAGE>
                                                                              22

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
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
<PAGE>
                                                                              23

                          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 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
<PAGE>
                                                                              24

income taxes) imposed on any Agent or any Lender as a result of a present or
former connection between such 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
such 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 any Agent or any
Lender hereunder, the amounts so payable to such Agent or such Lender shall be
increased to the extent necessary to yield to such 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
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 Agents and the Lenders
for any incremental taxes, interest or penalties that may become payable by any
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
<PAGE>
                                                                              25

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
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
<PAGE>
                                                                              26

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 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

the Borrower, the Administrative Agent or any other Lender shall have against
the replaced Lender.

                   SECTION 3.  REPRESENTATIONS AND WARRANTIES

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

                  3.1 Financial Condition. (a) The unaudited pro forma
consolidated balance sheet of the Borrower and its consolidated Subsidiaries as
at June 30, 2002 (including the notes
<PAGE>
                                                                              27

thereto) (the "Pro Forma Balance Sheet"), copies of which have heretofore been
furnished to each Lender, has been prepared giving effect (as if such events had
occurred on such date) to (i) the Loans to be made on the Closing Date and the
use of proceeds thereof and (ii) the payment of fees and expenses in connection
with the foregoing. The Pro Forma Balance Sheet has been prepared based on the
best information available to the Borrower as of the date of delivery thereof,
and presents fairly on a pro forma basis the estimated financial position of
Borrower and its consolidated Subsidiaries as at June 30, 2002, assuming that
the events specified in the preceding sentence had actually occurred at such
date.

                  (b) The audited consolidated balance sheets of the Borrower as
at December 31, 2000 and December 31, 2001 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 date, 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 June 30, 2002, and the related
unaudited consolidated statements of income and cash flows for the 6-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 6-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 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,
2001 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, 2001, except as disclosed in
the Borrower's Form 10-K for the fiscal year ended December 31, 2001 and Form
10-Q for the fiscal quarters ended March 31, 2002 and June 30, 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.
<PAGE>
                                                                              28

                  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 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
<PAGE>
                                                                              29

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 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.
The California Public Utilities Commission has issued an order, which remains in
full force and effect, exempting the Borrower from any requirement to obtain the
consent of the California Public Utilities Commission in connection with any
financing transaction or granting of a security interest. 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.
<PAGE>
                                                                              30

                  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 and the public utility laws and
regulations of California administered by the California Public Utilities
Commission (as to which the Borrower has received an exemptive order which
remains in full force and effect)).

                  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.

                  (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, except as disclosed on Schedule
3.16.

                  3.17 Use of Proceeds. The proceeds of the Loans shall be used
to refinance existing indebtedness of the Borrower.

                  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 within the
period of all applicable statutes of limitation have been, in compliance with
all applicable Environmental Laws; (ii) hold all Environmental Permits (each of
which is in full force and effect) required for any of their current or intended
operations or for any property owned, leased, or otherwise
<PAGE>
                                                                              31

operated by any of them; (iii) are, and within the period of all applicable
statutes of limitation have been, in compliance with all of their Environmental
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 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, the Confidential
Information Memorandum 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 (or, in the case of the
<PAGE>
                                                                              32

Confidential Information Memorandum, as of the date of this Agreement), 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, in the Confidential Information Memorandum or in any other documents,
certificates and statements furnished to the Agents 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 C 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 C Mortgage Bond and proceeds thereof, and, when
perfected by delivery of the G&R Series C 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 C Mortgage Bond and the proceeds thereof, as security for the
Obligations, in each case prior and superior in right to any other Person.

                  (b) The G&R Series C Mortgage Bond has been duly and validly
issued and is entitled to the security and benefits of the General and Refunding
Mortgage Indenture; is secured equally and ratably with, and only with, all
other securities issued and outstanding under the General and Refunding Mortgage
Indenture; is secured by direct and valid, duly perfected Liens on and security
interests in the Mortgaged Property (as defined in the General and Refunding
Mortgage Indenture), subject only to the prior Lien of the First Mortgage
Indenture and to Permitted Liens (as such term is defined in the General and
Refunding Mortgage Indenture); and constitutes collateral security for the
obligations of the Borrower as purported to be provided in the General and
Refunding Mortgage Indenture and herein.

                  3.21 Solvency. The Borrower is, and after giving effect to the
incurrence of all Indebtedness and obligations being incurred in connection
herewith and therewith will be and will continue to be, Solvent.

                             SECTION 8.  THE AGENTS

                  8.1 Appointment. Each Lender hereby irrevocably designates and
appoints the Agents as the agents of such Lender under this Agreement and the
other Loan Documents, and each Lender irrevocably authorizes each 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 such 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, no Agent shall 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 any Agent.

                  8.2 Delegation of Duties. Each 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 such duties. No Agent shall 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
<PAGE>
                                                                              49

in any certificate, report, statement or other document referred to or provided
for in, or received by the Agents 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 Agents 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 Agents. Each 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 such Agent. The Agents may deem and treat the payee of any
Term Note as the owner thereof for all purposes unless such Term 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. Each 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. No Agent shall be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless such 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 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 Agents and Other Lenders. Each Lender
expressly acknowledges that neither any of the Agents 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
<PAGE>
                                                                              50

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 Agents 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 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.
<PAGE>
                                                                              51

                  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. The Syndication Agent may, at
any time, by notice to the Lenders and the Administrative Agent, resign as
Syndication Agent hereunder, whereupon the duties, rights, obligations and
responsibilities of the Syndication Agent hereunder shall automatically be
assumed by, and inure to the benefit of, the Administrative Agent, without any
further act by the Syndication Agent, the Administrative Agent or any Lender.
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 Syndication Agent. Neither the Arranger
nor the Syndication Agent, in their respective capacities as such, shall have no
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 Agents 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 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
<PAGE>
                                                                              52

                          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 C 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;

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

                  (v)     amend, modify or waive any provision of Section 9.6
                          without the consent of each Lender.

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 Agents and all future holders of the Loans. In the case of any
waiver, the Borrower, the Lenders and the Agents 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 C 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
telecopy), and, unless otherwise expressly provided herein, shall be deemed to

no delay in exercising, on the part of any Agent or any Lender, any right,
remedy, power or privilege hereunder or under the other Loan Documents shall

and thereby, including, without limitation, the reasonable fees and
disbursements and other charges of counsel to the Administrative Agent and the
charges of Intralinks, (b) to pay or reimburse each Lender and the Agents for
all their costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, the G&R Series C Mortgage Bond,

or therewith, including, without limitation, the fees and disbursements of

in-house counsel) to each Lender and of counsel to the Agents, (c) to pay,
indemnify, or reimburse each Lender and the Agents for, and hold each Lender and
the Agents harmless from, any and all recording and filing fees and any and all
liabilities with respect to, or resulting from any delay in paying, stamp,

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

or reimburse each Lender, each Agent, their respective affiliates, and their
respective officers, directors, trustees, employees, advisors, agents and
controlling persons (each, an "Indemnitee") for, and hold each Indemnitee
harmless from and against any and all other liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever with respect to the execution, delivery,
enforcement, performance and administration of this Agreement, the G&R Series C
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 the Term Loan Facility. 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

<PAGE>
                                                                              55

Agent. The agreements in this Section shall survive repayment of the Loans and
all other amounts payable hereunder.

                  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 Agents, 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 Agents and each Lender.

                  (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 Agents 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
<PAGE>
                                                                              56

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 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 Term Notes evidencing
such Loans recorded therein for all purposes of this Agreement. Any assignment
of any Loan, whether or not evidenced by a Term Note, shall be effective only
upon appropriate entries with respect thereto being made in the Register (and
each Term Note shall expressly so provide). Any assignment or transfer of all or
part of a Loan evidenced by a Term Note shall be registered on the Register only
upon surrender for registration of assignment or transfer of the Term Note
evidencing such Loan, accompanied by a duly executed Assignment and Acceptance;
thereupon one or more new Term Notes in the same aggregate principal amount
shall be issued to the designated Assignee, and the old Term 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 Lehman 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
<PAGE>
                                                                              57

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 Term Notes, of the
assigning Lender) a new applicable Term 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 Term Note, to the order of the Assignor in an amount
equal to the applicable Loan, as the case may be, retained by it hereunder. Such
new Term Note or Term Notes shall be dated the Closing Date and shall otherwise
be in the form of the Term Note or Term 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 Term Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests in Loans and Term Notes,
including, without limitation, any pledge or assignment by a Lender of any Loan
or Term 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

                                                                              58

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 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 or of a Lender Addendum 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 Agents, 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:

                  (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 Agents 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

                  9.14 Confidentiality. Each of the Agents 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

its employees, directors, agents, attorneys, accountants and other professional

                  9.15 [Reserved].

                  9.16 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.

                               MATERIAL LITIGATION

         1. In early May of 2002, Coral Energy Canada, Enron North America
Corporation, Enron Power Marketing, Inc. ("Enron"), J. Aron & Company, National
Fuel Marketing Company, Nexen Marketing, Reliant Canada Incorporated, Reliant
Energy Services Incorporated and Retex, Inc. Reliant Energy Services, Inc. and
several smaller suppliers notified the Borrower that they would be terminating
their power and gas deliveries to the Borrower under the Western Systems Power
Pool Agreement ("WSPPA"). On September 30, 2002, El Paso Merchant Energy Group
notified the Borrower that it was terminating its power deliveries to the
Borrower under the WSPAA. Each of these terminating suppliers has asserted, or
has indicated that it will assert, a claim against the Borrower for liquidated
damages. See Schedule 3.7.

         2. Enron Power Marketing, Inc. v. Nevada Power Company and Sierra
Pacific Power Company (In re Enron Corp., et al., Case No. 01-16034). On June 5,
2002, Enron filed suit against the Borrower in its bankruptcy case in the
Bankruptcy Court for the Southern District of New York asserting claims for
liquidated damages related to the termination of its power supply agreement with
the Borrower of $93.5 million. Enron's claim is subject to the Borrower's
defense that such claim is already at issue in the Borrower's Federal Energy
Regulatory Commission ("FERC") proceeding against Enron under Section 206 of the
Federal Power Act challenging the contract prices of the terminated power supply
agreement. In connection with the lawsuit filed by Enron in the Bankruptcy
Court, Enron has filed a motion to require the Borrower promptly to pay the full
amount of their claim pending the final resolution of the lawsuit.

         3. Sierra Pacific Power Company v. Public Utilities Commission of
Nevada. On August 22, 2002, the Borrower filed a lawsuit in the First Judicial
District Court of the State of Nevada in and for Carson City seeking judicial
review of the May 28, 2002 decision of the Public Utilities Commission of Nevada
(the "PUCN") denying the recovery of $53.1 million of the Borrower's deferred
energy costs incurred on behalf of its customers in 2001.

         4. In September 1994, Region VII of the United States Environmental
Protection Agency ("the EPA") notified the Borrower that it was being named as a
potentially responsible party ("PRP") regarding past improper handling of
Polychlorinated Biphenyls by PCB Treatment, Inc., located in Kansas City, Kansas
and Kansas City, Missouri (the "Sites"). The EPA is requesting that the Borrower
voluntarily pay an undefined, pro rata share of the ultimate clean-up costs at
the Sites. A number of the largest PRP's formed a steering committee (the
"Committee"), which is chaired by the Borrower. The responsibility of the
Committee is to direct clean-up activities, determine appropriate cost
allocation, and pursue actions against recalcitrant parties, if necessary. The
EPA issued an administrative order on consent requiring signatories to perform
certain investigative work at the Sites. The Site evaluations have been
completed. The EPA is developing an allocation formula to allocate the
remediation costs. The Borrower has recorded a preliminary liability for the
Sites of $650,000 of which approximately $136,000 has been spent

                                      lxiv
<PAGE>
through June 30, 2002. Once evaluations are completed, the Borrower will be in a
better position to estimate and record the ultimate liabilities for the Sites.

I.   PLEDGED SECURITIES

         A. TAX-EXEMPT ISSUES. The Borrower has entered into financing
agreements with Washoe County and Humboldt County, Nevada pursuant to which
those counties have issued tax-exempt bonds to fund various Borrower-sponsored
projects. The Borrower's obligations under each such financing agreement are
secured by First Mortgage Bonds issued under the Borrower's Indenture of
Mortgage dated as of December 1, 1940, as supplemented and amended (the "First
Mortgage Indenture") and pledged to the relevant tax-exempt bond trustee. The
First Mortgage Indenture imposes a lien on substantially all of Borrower's
property. In addition, the Counties have granted to the Trustee in each
transaction a security interest in Borrower's obligations to the County under
the relevant financing agreement. The following is a list of the tax-exempt
financings and the series of the Borrower's First Mortgage Bonds securing such

         THIS BOND DELIVERY AGREEMENT, made and entered into as of October 30,
2002 (the "Agreement"), by and between SIERRA PACIFIC POWER COMPANY, a
corporation duly organized and existing under the laws of the State of Nevada
(the "Company"), and LEHMAN COMMERCIAL PAPER INC., in its capacity as

                              W I T N E S S E T H:

         WHEREAS, the Company has entered into the Term Loan Agreement, dated as
of October 30, 2002 (as amended, supplemented, restated or otherwise modified
from time to time, the "Term Loan Agreement"), among the Company, the Agent, the
lenders party thereto from time to time (the "Lenders") and others; and

         WHEREAS, pursuant to the Term Loan Agreement, the Lenders have agreed
to make Loans (as defined in the Term Loan Agreement) to the Company, and it is
a condition precedent to the obligation of the Lenders that the Company execute
and deliver this Agreement and deliver the Bond (as defined below) to the Agent
pursuant hereto; and

         WHEREAS, to secure the repayment of the Obligations incurred pursuant
to the Term Loan Agreement, the Company has issued and hereby delivers to the
Agent, for its benefit and the ratable benefit of the Lenders under the Term
Loan Agreement, a General and Refunding Mortgage Bond, Series C, due October 31,
2005, No. C-1, in the principal amount of $100,000,000 (the "Bond"), issued
under that certain General and Refunding Mortgage Indenture, dated as of May 1,
2001, between the Company and The Bank of New York, as trustee (the "Trustee"),
as heretofore or hereafter supplemented, modified or amended from time to time
(the "Indenture").

         NOW, THEREFORE, in consideration of the premises and in order to induce
the Lenders to enter into the Term Loan Agreement and to make Loans to the
Company thereunder, the Company does hereby, subject to the terms hereof,
covenant and agree with the Agent, as follows:

                                    ARTICLE I

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         SECTION 1.1.      The Company hereby represents and warrants that:

         (a) It is a corporation duly incorporated and in good standing under
the laws of the State of Nevada, is not in violation of any provisions of its
Articles of Incorporation or its by-laws, has corporate power to enter into and
to perform its obligations under this Agreement, has duly authorized the
execution and delivery of this Agreement by proper corporate action, and neither
this Agreement nor the obligations on its part herein contained contravene or
constitute a default under any agreement, instrument or indenture or any
provision of its Articles of Incorporation or its by-laws or any other
requirement of law;

                                        1
<PAGE>
         (b) When delivered to the Agent hereunder, the Bond will have been duly
and validly authorized, authenticated, issued and delivered and will constitute
the legally valid and binding obligation of the Company, entitled to the
benefits as provided by the Indenture; and

         (c)      The Company expects that the performance by it of its
obligations hereunder will result in a financial benefit to it.

                                   ARTICLE II

                              DELIVERY OF THE BOND

         SECTION 2.1. The Company hereby delivers the Bond to the Agent, fully
registered in the name of the Agent, to secure payment of the principal of the
Loans to the Company made pursuant to the Term Loan Agreement and all interest
thereon and fees, costs, expenses and other amounts payable by the Company
thereunder (all such interest, fees, costs, expenses and other amounts, the
"Interest and Other Amounts").

         SECTION 2.2. The Bond is delivered by the Company, and such delivery is
acknowledged and accepted by the Agent, upon and subject to the following terms
and conditions:

         (a) NO TRANSFER OF BOND; EXCEPTION. Except as required to effect an
assignment to a successor-in-interest as Administrative Agent under the Term
Loan Agreement, the Agent shall not sell, assign or transfer the Bond held by
it. The Company may take such actions as it shall deem to be desirable,
including the placing of a legend on such Bond in substantially the following
form:

                           "This Bond is not transferable except to a successor
                  to the Administrative Agent under the Term Loan Agreement
                  referred to herein."

and the issuance of stop transfer instructions to the Trustee and any registrar
under the Indenture, to effect compliance with this restriction.

         (b) RELEASE OF BOND UPON TERMINATION OF TERM LOAN AGREEMENT. It is the
intent of this Agreement that the Agent shall at all times (during the term of
this Agreement) hold, as security for the payment of the principal of the Loans
and all Interest and Other Amounts, a face amount of the Bond equal to the
aggregate initial principal amount of the Loans under the Term Loan Agreement,
it being understood and agreed that the actual amount of principal payable in
respect of the Bond on any date of determination shall be its face amount or
such lesser amount as shall be equal to the aggregate principal amount of the
Loans outstanding under the Term Loan Agreement on such date (including, without
limitation, all Loans made pursuant to the Term Loan Agreement on such date).
Accordingly, the Agent agrees to surrender the Bond to the Company when all of
the principal of the Loans made pursuant to the Term Loan Agreement shall have
been indefeasibly paid in full in cash, all accrued and unpaid Interest and
Other Amounts payable pursuant to the Term Loan Agreement shall have been
indefeasibly paid in full in cash, and the Term Loan Agreement shall have been
terminated.

                                        2
<PAGE>
         (c) VOTING OF THE BOND. The Agent, as holder of the Bond, shall attend
or be represented by proxy at any meeting of bondholders under the Indenture as
to which it is entitled to vote under the Indenture. Either at such meeting, or
otherwise where approval or consent of holders of securities of the Company is
sought without a meeting, the Agent shall vote the Bond, or shall consent with
respect thereto, proportionately with what the signer of a Bondholder's
Certificate, as defined below, reasonably believes was the vote or consent of
the holders of all securities issued and outstanding under the Indenture (other
than the Bond).

         For purposes of this Section 2.2(c), "Bondholder's Certificate" means a
certificate signed by the temporary Chairman, the temporary Secretary, the
permanent Chairman, the permanent Secretary, or an Inspector of Votes at any
meeting or meetings of securityholders under the Indenture, or by the Trustee in
the case of consents of such securityholders which are sought without a meeting,
which states what the signer thereof reasonably believes was the proportionate
votes or consents of the holders of all securities (other than the Bond)
outstanding under the Indenture and counted for the purposes of determining
whether such securityholders have approved or consented to the matter put before
them.

         The provisions of this Section 2.2(c) relating to voting or consent
with respect to the Bond shall not apply, and the Agent may vote or consent with
respect to the Bonds without restriction in accordance with the terms of the
Indenture, if either (i) there shall have occurred and be continuing an Event of
Default under the Indenture or an "Event of Default" under the Term Loan
Agreement or (ii) the matter with respect to which the vote or consent is taken
is a matter which, under the terms of the Indenture, requires the approval or
consent of the holders of all securities then outstanding and affected by such
matter.

         SECTION 2.3. To the extent, if any, of the Company's right, title and
interest in the Bond, the Company hereby grants to the Agent, for the ratable
benefit of the Lenders, a security interest in all such right, title and
interest. The Agent shall have, in respect of such security interest, all rights
of a secured party under Article 9 of the Uniform Commercial Code in effect in
the State of New York.

                                   ARTICLE III

                                TERM; TERMINATION

         SECTION 3.1. This Agreement shall remain in full force and effect until
terminated in accordance with this Article III and shall not be affected,
modified or impaired by the happening from time to time of any event, including,
without limitation, any of the following, whether or not with notice to, or
consent of, the Company:

         (a) the extension of the time for payment of any principal of or
interest on the Loans made pursuant to the Term Loan Agreement or any Interest
and Other Amounts payable thereunder or of the time for performance of any other
obligation, covenant or agreement under the Indenture;

                                        3
<PAGE>
         (b) the modification, amendment, compromise, settlement, release,
waiver or termination (whether material or otherwise) of any obligation,
covenant or agreement of the Company under the Indenture;

         (c) the voluntary or involuntary liquidation, dissolution, sale or
other disposition of all or substantially all the assets, marshalling of assets,
bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition with creditors or readjustment of, or other similar
proceedings affecting, the Company or any of its assets, or any allegation of
the invalidity, or contest of the validity, of this Agreement in any such
proceeding;

         (d) to the extent permitted by law, the release or discharge, whether
by operation of law or otherwise, of the Company from the performance or
observance of any obligation, covenant or agreement under this Agreement; or

         (e) the default or failure of the Company fully to perform or observe
any obligation, covenant or agreement under this Agreement.

         SECTION 3.2. Upon the indefeasible payment in full in cash of the
principal of the Loans made pursuant to the Term Loan Agreement and all Interest
and Other Amounts payable thereunder and the termination of the Term Loan
Agreement, this Agreement shall terminate, and the Agent shall return the Bond
to the Company.

                                   ARTICLE IV

                                  MISCELLANEOUS

         SECTION 4.1. The Company shall fully satisfy and discharge all of the
obligations for the payment of the Bond in accordance with its terms, the terms
of the Indenture and the terms of this Agreement, it being the intention that
such obligations shall be separate and independent covenants from any agreements
of the Company with the Agent under the Term Loan Agreement and that such
obligations of the Company hereunder shall continue unaffected unless otherwise
expressly provided in this Agreement.

         SECTION 4.2. The Company, at its own expense, shall do such acts and
things, and execute and deliver such conveyances, assignments, assurances,
agreements, financing statements and instruments, as may at any time be required
or desirable in connection with this Agreement or relative to the Bond, in order
to assign, assure and confirm to the Agent a first priority perfected ownership
interest in the Bond.

         SECTION 4.3. This Agreement is entered into by the Company for the
benefit of the Agent and any successor-in-interest to the Agent as
Administrative Agent under the Term Loan Agreement, who shall be entitled to
enforce performance and observance of this Agreement to the same extent as if it
were a party signatory hereto.

         SECTION 4.4. No remedy herein conferred upon or reserved to the Agent
is intended to be exclusive of any other available remedies, but each and every
such remedy shall be cumulative and shall be in addition to every other remedy
given under this Agreement or now or

                                        4
<PAGE>
hereafter existing at law or in equity. In the event any provision contained in
this Agreement should be breached by the Company and thereafter duly waived by
the Agent, such waiver shall be limited to the particular breach so waived and
shall not be deemed to waive any other breach hereunder. No waiver, amendment,
release or modification of this Agreement shall be established by conduct,
custom or course of dealing, but solely by an instrument in writing duly
executed by the Agent.

         SECTION 4.5.     All amendments of this Agreement shall be in
writing.

         SECTION 4.6. This Agreement (together with the Term Loan Agreement)
constitutes the entire agreement, and supersedes all prior agreements and
understandings, both written and oral, between the parties with respect to the
subject matter hereof, and may be executed in several counterparts, each of
which shall be deemed an original, and all of which together shall constitute
one and the same instrument.

         SECTION 4.7. In the event any one or more phrases, clauses, sentences,
Sections or Articles of this Agreement shall be held invalid or unenforceable by
any court of competent jurisdiction, such holding shall not affect the validity
or enforceability of the remaining portions hereof.

         SECTION 4.8. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

         SECTION 4.9. Any notices, requests or other communications given or
