                             UNDERWRITING AGREEMENT



                                                             November 12, 2001

LEHMAN BROTHERS INC.
MERRILL LYNCH, PIERCE, FENNER & SMITH
           INCORPORATED
GOLDMAN SACHS & CO.
FIRST UNION SECURITIES, INC.
c/o Lehman Brothers Inc.
101 Hudson Street
Jersey City, N.J.  07302

Ladies and Gentlemen:

         Sierra Pacific Resources, a Nevada corporation (the "COMPANY"),
proposes, subject to the terms and conditions stated herein, to issue and sell
6,000,000 of its Corporate PIES (the "FIRM CORPORATE PIES") to Lehman Brothers
Inc. and the other underwriters named in Schedule 1 hereto (the "UNDERWRITERS").
In addition, the Company proposes to grant to the Underwriters an option to
purchase up to an additional 900,000 Corporate PIES on the terms and for the
purposes set forth in Section 2 (the "OPTION CORPORATE PIES" and, together with
the Firm Corporate PIES, the "CORPORATE PIES"). This is to confirm the agreement
between the Company and the Underwriters concerning the offer, issue and sale of
the Corporate PIES.

         Each Corporate PIES will consist of (a) a stock purchase contract (a
"PURCHASE CONTRACT") to be issued by the Company pursuant to a Purchase Contract
Agreement (the "PURCHASE CONTRACT AGREEMENT") to be entered into between the
Company and The Bank of New York, as Purchase Contract Agent (the "PURCHASE
CONTRACT AGENT"), under which (i) the holder will agree to purchase from the
Company, and the Company will agree to sell to the holder, on November 15, 2005,
for $50, a number of shares of its common stock, par value $1.00 per share (the
"COMMON STOCK"), equal to the settlement rate then in effect and as subject to
adjustment, in each case, as set forth in the Prospectus (as hereinafter
defined), and (ii) the Company will pay to the holder purchase contract
adjustment payments at the annual rate of 1.070% payable quarterly in arrears,
as set forth in the Prospectus, and (b) one of the Company's 7.930% Senior Notes
due 2007 (each, a "SENIOR NOTE"), having a principal amount of $50. The Company
will issue the Senior Notes pursuant to the Indenture, dated as of May 1, 2000
between the Company and The Bank of New York, as Trustee (the "TRUSTEE") (the
"ORIGINAL INDENTURE"), and the Officers' Certificate, dated as of November 16,
2001, establishing the terms and other provisions of the Senior Notes (the
"OFFICERS' CERTIFICATE," and together with the Original Indenture, the
"INDENTURE").




         In accordance with the terms of the Purchase Contract Agreement, the
holders of the Corporate PIES will pledge their Senior Notes to Wells Fargo Bank
Minnesota, National Association, as Collateral Agent (the "COLLATERAL AGENT"),
pursuant to a Pledge Agreement (the "PLEDGE AGREEMENT") to be entered into among
the Company, the Purchase Contract Agent, Wells Fargo Bank Minnesota, National
Association, as Securities Intermediary (the "SECURITIES INTERMEDIARY"), and the
Collateral Agent, to secure the holders' obligations to purchase Common Stock
under the Purchase Contracts. Under certain circumstances, holders of Corporate
PIES may substitute certain U.S. Treasury securities for the Senior Notes that
are a part of such holders' Corporate PIES and thereby create Treasury PIES (the
"TREASURY PIES") pursuant to the terms of the Purchase Contract Agreement and
the Pledge Agreement.

         In addition, the Senior Notes will be subject to remarketing to satisfy
the Corporate PIES holders' obligations to settle the Purchase Contract under
the Purchase Contract Agreement pursuant to a Remarketing Agreement (the
"REMARKETING AGREEMENT") to be entered into between the Company and Lehman
Brothers Inc., as Remarketing Agent (the "REMARKETING AGENT").

         1. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY. The
Company represents, warrants and agrees that:

              (a) FILINGS UNDER SECURITIES LAWS. (i) A registration statement on
Form S-3 (registration no. 333-72160) setting forth information with respect to
the Company and the Company's senior debt securities, shares of Common Stock,
stock purchase contracts and certain other securities (A) has been prepared by
the Company in conformity with the requirements of the Securities Act of 1933,
as amended, and the rules and regulations of the Securities and Exchange
Commission (the "COMMISSION") thereunder (collectively, the "SECURITIES ACT"),
(B) has been filed with the Commission under the Securities Act and (C) became
effective under the Securities Act on November 7, 2001, and the Indenture has
been qualified under the Trust Indenture Act of 1939, as amended and the rules
and regulations of the Commission thereunder (collectively, the "TRUST INDENTURE
ACT"). Copies of such registration statement and all exhibits thereto have been
delivered by the Company to you. As used in this Agreement, "EFFECTIVE TIME"
means the date and the time as of which such registration statement, or the most
recent post-effective amendment thereto, if any, was declared effective by the
Commission; "EFFECTIVE DATE" means the date of the Effective Time; "PRELIMINARY
PROSPECTUS" means each prospectus included in such registration statement, or
amendments thereof, before it became effective under the Securities Act and any
prospectus filed with the Commission by the Company with the consent of Lehman
Brothers Inc. pursuant to Rule 424(a) under the Securities Act; "REGISTRATION
STATEMENT" means such registration statement, as amended as of the Effective
Time, including all information contained in the final prospectus filed with the
Commission pursuant to Rule 424(b) under the Securities Act and deemed to be a
part of the registration statement as of the Effective Time pursuant to Rule
430A of the Securities Act; and "PROSPECTUS" means the prospectus (including any
supplement thereto) in the form first used to confirm sales of Corporate PIES.
The Commission has not issued any order


                                       2



preventing or suspending the use of any Preliminary Prospectus or the
Registration Statement.

              (ii) Pursuant to Rule 429 under the Securities Act the Prospectus
will be used as a combined prospectus relating to the Registration Statement and
to the registration statement filed by the Company with the Commission on June
7, 1999 (registration no. 333-80149) which, as subsequently amended, became
effective on May 3, 2000. Unless the context otherwise requires, all references
in this Agreement to the Registration Statement shall be deemed to include such
prior registration statement.

              (iii) All references in this Agreement to the Registration
Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer
to and include all documents incorporated by reference in the Registration
Statement, any Preliminary Prospectus or the Prospectus, as the case may be (the
"INCORPORATED DOCUMENTS"); and all references in this Agreement to amendments or
supplements to the Registration Statement, any Preliminary Prospectus or the
Prospectus shall be deemed to refer to and include any document filed under the
Securities Exchange Act of 1934, as amended, and the rules and regulations of
the Commission thereunder (collectively, the "EXCHANGE ACT"), which is
incorporated by reference in the Registration Statement, such Preliminary
Prospectus or the Prospectus, as the case may be.

              (b) ELIGIBILITY FOR FORM S-3. The conditions for use of Form S-3,
as set forth in the General Instructions thereto, have been satisfied.

              (c) COMPLIANCE WITH REGISTRATION REQUIREMENTS. The Registration
Statement conforms, and the Prospectus and any further amendments or supplements
to the Registration Statement or the Prospectus will, when they become effective
or are filed with the Commission, as the case may be, conform in all respects to
the requirements of the Securities Act and do not and will not, as of the
applicable Effective Date (as to the Registration Statement and any amendment
thereto) and as of the applicable filing date (as to the Prospectus and any
amendment or supplement thereto) contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading; PROVIDED THAT, the Company makes no
representation or warranty as to information contained in or omitted from the
Registration Statement or the Prospectus in reliance upon and in conformity with
written information furnished to the Company by any Underwriter through Lehman
Brothers Inc. specifically for inclusion therein. The Indenture conforms in all
material respects to the requirements of the Trust Indenture Act.

              (d) INCORPORATED DOCUMENTS. (i) The Incorporated Documents when
they became effective or were filed with the Commission, as the case may be,
conformed in all material respects to the requirements of the Securities Act or
the Exchange Act, as applicable, and none of such documents contained any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements therein not misleading;
and any further documents so filed and incorporated by reference in the
Prospectus, when such documents are filed with the Commission, will conform in
all material respects to the requirements of the Exchange Act and will not
contain any untrue statement of a material fact or omit to state any material
fact required to be


                                       3



stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading.

              (e) GOOD STANDING. Each of the Company and its Significant
Subsidiaries (as defined below) has been duly organized and is validly existing
as a corporation in good standing under the laws of the State of Nevada, is duly
qualified to do business and is in good standing as a foreign business entity in
each jurisdiction in which its ownership or lease of property or the conduct of
its businesses requires such qualification, and has all corporate power and
authority necessary to own, lease or hold its properties and to conduct the
businesses in which it is engaged, except where the failure to so qualify or to
be in good standing would not have a material adverse effect on the business,
affairs, management, condition (financial or otherwise), stockholders' equity or
results of operations of the Company and its subsidiaries considered as a whole
(a "Material Adverse Effect"); and none of the subsidiaries of the Company other
than Nevada Power Company and Sierra Pacific Power Company is a "significant
subsidiary," as such term is defined in Rule 405 of the Securities Act (each, a
"SIGNIFICANT SUBSIDIARY").

              (f) CAPITALIZATION. The Company has an authorized capitalization
as set forth in the Company's consolidated statement of capitalization as of
December 31, 2000 incorporated by reference in the Prospectus; all of the issued
shares of capital stock of the Company have been duly and validly authorized and
issued and are fully paid and non-assessable; all of the issued shares of
capital stock or other ownership interests of each subsidiary of the Company
have been duly and validly authorized and issued and are fully paid and
non-assessable; and all shares of the issued and outstanding common stock of the
Company's Significant Subsidiaries are owned by the Company; and all shares of
capital stock or other ownership interests of each subsidiary of the Company
which are owned, directly or indirectly, by the Company are so owned free and
clear of all liens, encumbrances, equities, claims or adverse interests
(collectively, "LIENS") of any nature. There has been no change in the
outstanding capital stock of the Company or any of its subsidiaries since
September 30, 2001 in the Prospectus except with respect to changes in
outstanding Common Stock resulting from transactions relating to employee
benefit plans, non-employee director plans or the common stock investment plan
existing on the date hereof.

              (g) ABSENCE OF PROCEEDINGS. Except as described in the Prospectus,
there are no legal or governmental proceedings pending to which the Company or
any of its subsidiaries is a party or of which any property or assets of the
Company or any of its subsidiaries is the subject which, if determined adversely
to the Company or such subsidiary, would be reasonably likely to result in a


                                       4



Material Adverse Effect; and, to the best of the Company's knowledge, no such
proceedings are threatened or contemplated by governmental authorities or
threatened by others.

              (h) ABSENCE OF DEFAULTS. Except circumstances which are not
reasonably likely, individually or in the aggregate, to result in a Material
Adverse Effect, neither the Company nor any of its subsidiaries (i) is in
violation of its charter or by-laws, (ii) is in default, and no event has
occurred which, with notice or lapse of time or both, would constitute such a
default, in the due performance or observance of any term, covenant or condition
contained in any indenture, mortgage, deed of trust, loan agreement or other
agreement or instrument to which it is a party or by which it is bound or to
which any of its properties or assets is subject or (iii) is in violation of any
law, ordinance, governmental rule, regulation or court decree to which it or its
property or assets may be subject or has failed to obtain any license, permit,
certificate, franchise or other governmental authorization or permit relating to
the ownership of its property or to the conduct of its business.

              (i) REGISTRATION RIGHTS. Except as described in the Prospectus,
there are no contracts, agreements or understandings between the Company and any
person granting such person the right to require the Company to file a
registration statement under the Securities Act with respect to any securities
of the Company owned or to be owned by such person.

              (j) NO MATERIAL LOSS; NO MATERIAL ADVERSE CHANGE. Except as set
forth in or contemplated by the Prospectus, (i) neither the Company nor any of
its subsidiaries has sustained, since the date of the latest audited financial
statements included in the Prospectus, any material loss or interference with
its business from fire, explosion, flood or other calamity, whether or not
covered by insurance, or from any labor dispute or court or governmental action,
order or decree (a "MATERIAL LOSS"); and, (ii) since such date, there has not
been any change in the capital stock, short-term debt or long-term debt of the
Company or any of its subsidiaries or any material adverse change, or any
development reasonably likely to result in a material adverse change, in or
affecting the business, general affairs, management, consolidated financial
position, stockholders' equity, or results of operations of the Company and its
subsidiaries considered as a whole (a "MATERIAL ADVERSE CHANGE").

              (k) FINANCIAL STATEMENTS. The financial statements (including the
related notes and supporting schedules) incorporated by reference in the
Prospectus (and any supplement thereto) present fairly the financial condition,
the results of operations and the changes in financial position of the Company
and its consolidated subsidiaries on the basis stated therein at the respective
dates or for the respective periods to which they apply; such statements and
related schedules and notes have been prepared in accordance with generally
accepted accounting principles consistently applied, except as noted therein,
throughout the periods involved; the supporting schedules, if any, incorporated
by reference in the


                                       5



Prospectus present fairly in accordance with generally accepted accounting
principles the information required to be stated therein; and the other
financial and statistical information and data set forth or incorporated by
reference in the Prospectus (and any supplement thereto) are, in all material
respects, accurately presented and prepared on a basis consistent with such
financial statements and the books and records of the Company.

              (l) INDEPENDENT ACCOUNTANTS. Deloitte & Touche LLP (the
"ACCOUNTANTS"), who have certified the financial statements of the Company and
whose report is incorporated by reference in the Prospectus are independent
public accountants as required by the Securities Act; and the Accountants were
independent accountants as required by the Securities Act during the periods
covered by the financial statements on which they reported.

              (m) TITLE TO PROPERTY. The Company and its Significant
Subsidiaries have good and marketable title in fee simple to all real property
and good and marketable title to all personal property owned by them, in each
case free and clear of all liens, encumbrances and defects, except such as are
(i) described or referred to in the Prospectus or (ii) do not, individually or
in the aggregate, affect the value of such property or interfere with the use
made and proposed to be made of such property to such extent as might reasonably
be expected to result in a Material Adverse Effect; and all assets held under
lease by the Company and its Significant Subsidiaries are held by them under
valid, subsisting and enforceable leases, with such exceptions as are not
material to the Company and its subsidiaries considered as a whole, and such
leases do not interfere with the use made and proposed to be made of such
property and buildings by the Company and its Significant Subsidiaries to such
extent as would be reasonably likely to result in a Material Adverse Effect.

              (n) POSSESSION OF LICENSES AND PERMITS. Each of the Company and
its Significant Subsidiaries has such permits, licenses, consents, exemptions,
franchises, authorizations and other approvals (each, an "AUTHORIZATION") of,
and has made all filings with and notices to, all governmental or regulatory
authorities and self-regulatory organizations and all courts and other
tribunals, including, without limitation, under any applicable environmental
law, ordinance, rule, regulation, order, judgment, decree or permit, as are
necessary to own, lease, license and operate its respective properties and to
conduct its business, except where the failure to have any such Authorization or
to make any such filing or notice would not have a Material Adverse Effect.
Except for circumstances which are not reasonably likely to result in a Material
Adverse Effect, (i) each such Authorization is valid and in full force and
effect and each of the Company and its Significant Subsidiaries, as the case may
be, is in compliance with all the terms and conditions thereof and with the
rules and regulations of the authorities and governing bodies having
jurisdiction with respect thereto; (ii) no event has occurred (including,
without limitation, the receipt of any notice from any authority or governing
body) which allows or, after notice or lapse of time or both, would allow,
revocation, suspension or termination of any such


                                       6



Authorization or results or, after notice or lapse of time or both, would result
in any other impairment of the rights of the holder of any such Authorization;
and (iii) except as disclosed in the Prospectus, such Authorizations contain no
restrictions that are burdensome to the Company or any of its Significant
Subsidiaries.

              (o) NO MATERIAL TRANSACTIONS, ETC.. Since the date as of which
information is given in the Prospectus and except as otherwise disclosed in the
Prospectus, (i) neither the Company nor any of its Significant Subsidiaries has
incurred any liability or obligation, direct or contingent, or entered into any
transaction which liability, obligation or transaction is (A) not in the

required to be stated therein or is necessary to make the statements therein not
misleading.

              (c) CORPORATE PROCEEDINGS. All corporate proceedings and other

general affairs, management, condition (financial or otherwise), stockholders'

of Lehman Brothers Inc., so material (with respect to the Company and its


                                       19



subsidiaries taken as a whole) and adverse as to make it impracticable or

manner contemplated in the Prospectus and this Agreement.

              (o) NO DOWNGRADE. Subsequent to the execution and delivery of this

or any of its nationals or properties or (iv) there shall have occurred such a
calamity or crisis or such a material adverse change in general domestic or
international economic, political or financial conditions, including without
limitation as a result of terrorist activities (or the effect of international
conditions on the financial markets in the United States shall be such) as to
make it, in the judgment of Lehman Brothers Inc., impracticable or inadvisable
to proceed with the public offering or delivery of the Corporate PIES being
delivered on such Delivery Date on the terms and in the manner contemplated in
the Prospectus.

         All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel to the Underwriters.

         8. INDEMNIFICATION AND CONTRIBUTION.

              (a) INDEMNIFICATION OF UNDERWRITERS. The Company shall indemnify
and hold harmless each Underwriter, its officers and employees, each of its


                                       20



directors, and each person, if any, who controls any Underwriter within the
meaning of the Securities Act, from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including, but
not limited to, any loss, claim, damage, liability or action relating to
purchases and sales of the Corporate PIES), to which that Underwriter, officer,
employee or controlling person may become subject, under the Securities Act or
otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a
material fact contained in any (A) Preliminary Prospectus, the Registration
Statement or the Prospectus or in any amendment or supplement thereto, or (B)
any blue sky application or other document prepared or executed by the Company
(or based upon any written information furnished by the Company) filed in any
jurisdiction specifically for the purpose of qualifying any or all of the
Corporate PIES under the securities laws of any state or other jurisdiction
(such application, document or information being hereinafter called a "BLUE SKY
APPLICATION"), (ii) the omission or alleged omission to state in any Preliminary
Prospectus, the Registration Statement, the Prospectus, or in any amendment or
supplement thereto or in any Blue Sky Application any material fact required to
be stated therein or necessary to make the statements therein not misleading or
(iii) any act or failure to act or any alleged act or failure to act by any
Underwriter in connection with, or relating in any manner to, the Corporate PIES
or the offering contemplated hereby, and which is included as part of or
referred to in any loss, claim, damage, liability or action arising out of or
based upon matters covered by clause (i) or (ii) above (PROVIDED THAT, the
Company shall not be liable under this clause (iii) to the extent that it is
determined in a final judgment by a court of competent jurisdiction that such
loss, claim, damage, liability or action resulted directly from any such acts or
failure to act undertaken or omitted to be taken by such Underwriter through its
gross negligence or willful misconduct), and shall reimburse each Underwriter
and each such officer, employee, director or controlling person promptly upon
demand for any legal or other expenses reasonably incurred by that Underwriter,
officer, employee or controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred; provided, however, that the Company
shall not be liable in any such case to the extent that any such loss, claim,
damage, liability or action arises out of, or is based upon, any untrue
statement or alleged untrue statement or omission or alleged omission made in
any Preliminary Prospectus, the Registration Statement or the Prospectus, or in
any such amendment or supplement, in reliance upon and in conformity with the
written information concerning such Underwriter furnished to the Company through
Lehman Brothers Inc. by or on behalf of any Underwriter specifically for
inclusion therein which information consists solely of the information specified
in Section 8(e); and provided, further, that the Company shall not be liable to
indemnify any Underwriter or any person who controls such Underwriter on account
of any such loss, liability, claim, damage or expense arising out of any such
defect or alleged defect in any Preliminary Prospectus if a copy of the
Prospectus (exclusive of the Incorporated Documents) shall not have been given


                                       21



or sent by such Underwriter with or prior to the written confirmation of the
sale involved to the extent that (i) the Prospectus would have cured such defect
or alleged defect and (ii) sufficient quantities of the Prospectus were timely
made available to such Underwriter. The foregoing indemnity agreement is in
addition to any liability which the Company may otherwise have to any
Underwriter or to any officer, employee or controlling person of that
Underwriter.

              (b) INDEMNIFICATION OF COMPANY, DIRECTORS AND OFFICERS. Each
Underwriter, severally and not jointly, shall indemnify and hold harmless the
Company, its officers and employees, each of its directors, and each person, if
any, who controls the Company within the meaning of the Securities Act from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof, to which the Company or any such director, officer or
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus or in any amendment or supplement thereto or in any Blue Sky
Application or (ii) the omission or alleged omission to state in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or in any amendment or
supplement thereto or in any Blue Sky Application, any material fact required to
be stated therein or necessary to make the statements therein not misleading,
but in each case only to the extent that the untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with the written information furnished to the Company through Lehman
Brothers Inc. by or on behalf of that Underwriter specifically for inclusion
therein and described in Section 8(c), and shall reimburse the Company and any
such director, officer or controlling person promptly upon demand for any legal
or other expenses reasonably incurred by the Company or any such director,
officer or controlling person in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action as
such expenses are incurred. The foregoing indemnity agreement is in addition to
any liability which any Underwriter may otherwise have to the Company or any
such director, officer, employee or controlling person.

              (c) NOTIFICATION; ACTION AGAINST PARTIES; SETTLEMENT WITHOUT
CONSENT IF FAILURE TO REIMBURSE. Promptly after receipt by an indemnified party
under this Section 8 of notice of any claim or the commencement of any action,
the indemnified party shall, if a claim in respect thereof is to be made against
the indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure and, PROVIDED, FURTHER, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 8.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying


                                       22



party thereof, the indemnifying party shall be entitled to participate therein
and, to the extent that it wishes, jointly with any other similarly notified
indemnifying party, to assume the defense thereof with counsel satisfactory to
the indemnified party. After notice from the indemnifying party to the
indemnified party of its election to assume the defense of such claim or action,
the indemnifying party shall not be liable to the indemnified party under this
Section 8 for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof other than reasonable
costs of investigation; PROVIDED, HOWEVER, that the Underwriters shall have the
right to employ separate counsel to represent jointly the Underwriters and their
respective officers, employees and controlling persons who may be subject to
liability arising out of any claim in respect of which indemnity may be sought
by the Underwriters against the Company under this Section 8 if, in the
reasonable judgment of such Underwriters, it is advisable for such Underwriters,
officers, employees and controlling persons to be jointly represented by
separate counsel, and in that event the fees and expenses of such separate
counsel shall be paid by the Company. No indemnifying party shall, (i) without
the prior written consent of the indemnified parties (which consent shall not be
unreasonably withheld), settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment of the plaintiff in any such action, the
indemnifying party shall indemnify and hold harmless any indemnified party from
and against any loss or liability by reason of such settlement or judgment.

              (d) CONTRIBUTION. If the indemnification provided for in this
Section 8 shall for any reason be unavailable or insufficient to hold harmless
an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim,
damage or liability, or any action in respect thereof, referred to therein, then
each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company on the one hand and the Underwriters on the other from
the offering of the Corporate PIES or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company on the one hand and the
Underwriters on the other with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Underwriters on the other with
respect to such offering shall be deemed to be in the same


                                       23



proportion as the total net proceeds from the offering of the Corporate PIES
purchased under this Agreement (before deducting expenses) received by the
Company, on the one hand, and the total underwriting discounts and commissions
received by the Underwriters with respect to the Corporate PIES purchased under
this Agreement, on the other hand, bear to the total gross proceeds from the
offering of the Corporate PIES under this Agreement, in each case as set forth
in the table on the cover page of the Prospectus. The relative fault shall be
determined by reference to whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or the Underwriters, the intent of the
parties and their relative knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company and the Underwriters
agree that it would not be just and equitable if contributions pursuant to this
Section 8(d) were to be determined by pro rata allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation which does not take into account the equitable considerations
referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section shall be deemed to include, for purposes of
this Section 8(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Corporate PIES underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such Underwriter has otherwise paid or become liable to pay by reason of any
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Underwriters' obligations
to contribute as provided in this Section 8(d) are several in proportion to
their respective underwriting obligations and not joint.

              (e) INFORMATION FURNISHED BY UNDERWRITERS. The Underwriters
severally confirm that the statements in the last paragraph on the cover page of
the Prospectus and the third, seventh, eighth, eleventh and fifteenth paragraphs
under the caption "Underwriting" in the Prospectus are correct; and the
Underwriters severally further confirm, and the Company acknowledges, that such
statements constitute the only information concerning such Underwriters
furnished in writing to the Company through Lehman Brothers Inc. by or on behalf
of the Underwriters specifically for inclusion in the Registration Statement and
the Prospectus.

         9. DEFAULTING UNDERWRITERS. If, on any Delivery Date, any Underwriter
defaults in the performance of its obligations under this Agreement, the
remaining non-defaulting Underwriters shall be obligated to purchase the
principal amount of Corporate PIES which the defaulting Underwriter agreed but
failed to purchase on such Delivery Date in the


                                       24



respective proportions which the principal amount of the Firm Corporate PIES set
forth opposite the name of each remaining non-defaulting Underwriter in Schedule
1 hereto bears to the aggregate principal amount of Firm Corporate PIES set
forth opposite the names of all the remaining non-defaulting Underwriters in
Schedule 1 hereto; PROVIDED, HOWEVER, that the remaining non-defaulting
Underwriters shall not be obligated to purchase any of the Corporate PIES on
such Delivery Date if the total aggregate principal amount of the Corporate PIES
which the defaulting Underwriter or Underwriters agreed but failed to purchase
on such date exceeds 9.09% of the total aggregate principal amount of the
Corporate PIES to be purchased on such Delivery Date, and any remaining
non-defaulting Underwriter shall not be obligated to purchase more than 110% of
the total aggregate principal amount of the Corporate PIES which it agreed to
purchase on such Delivery Date pursuant to the terms of Section 3. If the
foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or
those other underwriters satisfactory to Lehman Brothers Inc. who so agree,
shall have the right, but shall not be obligated, to purchase, in such
proportion as may be agreed upon among them, the total aggregate principal
amount of Corporate PIES to be purchased on such Delivery Date. If the remaining
Underwriters or other underwriters satisfactory to Lehman Brothers Inc. do not
elect to purchase on such Delivery Date the aggregate principal amount of
Corporate PIES which the defaulting Underwriter or Underwriters agreed but
failed to purchase on such Delivery Date, this Agreement (or, with respect to
the Option Delivery Date, the obligation of the Underwriters to purchase, and of
the Company to sell, the Option Corporate PIES) shall terminate without
liability on the part of any non-defaulting Underwriter or the Company, except
that the Company will continue to be liable for the payment of expenses to the
extent set forth in Sections 6 and 11. As used in this Agreement, the term
"Underwriter" includes, for all purposes of this Agreement unless the context
requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to
this Section 9, purchases Corporate PIES which a defaulting Underwriter agreed
but failed to purchase.

         Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default. If other
underwriters are obligated or agree to purchase the Corporate PIES of a
defaulting or withdrawing Underwriter, either Lehman Brothers Inc. or the
Company may postpone the Delivery Date for up to seven full business days in
order to effect any changes that in the opinion of counsel to the Company or
counsel for the Underwriters may be necessary in the Registration Statement, the
Prospectus or in any other document or arrangement.

         10. TERMINATION. The obligations of the Underwriters hereunder may be
terminated by the Underwriters by notice given to and received by the Company
prior to delivery of and payment for the Corporate PIES if, prior to that time,
any of the events described in Sections 7(n), 7(o) or 7(p) shall have occurred
or if the Underwriters shall decline to purchase the Firm Corporate PIES for any
reason permitted under this Agreement.

         11. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If (a) the Company shall
fail to tender the Corporate PIES for delivery to the Underwriters by reason of
any failure, refusal or inability on the part of the Company to perform any
agreement on its part to be performed, or because any other condition of the
Underwriters' obligations hereunder required to be fulfilled by the Company
(including, without limitation, with respect to the transactions) is not
fulfilled or (b) the Underwriters shall decline to purchase the Corporate PIES
for any reason permitted under


                                       25



this Agreement (including the termination of this Agreement pursuant to Section
10), the Company shall reimburse the Underwriters for all reasonable
out-of-pocket expenses (including fees and disbursements of counsel) incurred by
the Underwriters in connection with this Agreement and the proposed purchase of
the Corporate PIES, and upon demand the Company shall pay the full amount
thereof to the Underwriters. If this Agreement is terminated pursuant to Section
9 by reason of the default of one or more Underwriters, the Company shall not be
obligated to reimburse any defaulting Underwriter on account of those expenses.

         12. NOTICES, ETC. All statements, requests, notices and agreements
hereunder shall be in writing, and:

              (a) if to the Underwriters, shall be delivered or sent by mail,

Underwriter at its address set forth in its acceptance telex to Lehman Brothers

shall take effect at the time of receipt thereof. The Company shall be entitled

behalf of the Underwriters by Lehman Brothers Inc.

         13. PERSONS ENTITLED TO BENEFIT OF AGREEMENT. This Agreement shall
inure to the benefit of and be binding upon the Underwriters, the Company, and
their respective successors. This Agreement and the terms and provisions hereof
are for the sole benefit of only those persons, except that (A) the
representations, warranties, indemnities and agreements of the Company contained
in this Agreement shall also be deemed to be for the benefit of the directors,
officers and employees of the Underwriters and the person or persons, if any,
who control any Underwriter within the meaning of Section 15 of the Securities
Act and (B) any indemnity agreement of the Underwriters contained in Section
8(b) of this Agreement shall be deemed to be for the benefit of directors,
officers and employees of the Company, and any person controlling the Company
within the meaning of Section 15 of the Securities Act. Nothing in this
Agreement


                                       26



is intended or shall be construed to give any person, other than the persons
referred to in this Section 13, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision contained herein.

         14. SURVIVAL. The respective indemnities, representations, warranties

FIRST UNION SECURITIES, INC.
c/o Lehman Brothers Inc.
101 Hudson Street
Jersey City, N.J.  07302

Ladies and Gentlemen:

         The undersigned understands that you propose to enter into an
underwriting agreement (the "UNDERWRITING AGREEMENT") providing for the purchase
by you and such other firms (the "UNDERWRITERS") of 6,000,000 Corporate PIES
(the "CORPORATE PIES") of Sierra Pacific Resources, a Nevada corporation (the
"COMPANY"), and that the Underwriters propose to reoffer the Corporate PIES to
the public pursuant to the Underwriting Agreement (the "OFFERING").

         In consideration of the execution of the Underwriting Agreement by the
Underwriters, and for other good and valuable consideration, the undersigned
hereby irrevocably agrees that, without the prior written consent of Lehman
Brothers Inc., on behalf of the Underwriters, the undersigned will not, directly
or indirectly, (1) offer for sale, sell, pledge or otherwise dispose of (or
enter into any transaction or device which is designed to, or could be expected
to, result in the disposition by any person at any time in the future of) any
shares of the Company's common stock, par value $1.00 per share (the "COMMON
STOCK") or any securities convertible into or exchangeable for Common Stock or
substantially similar securities (other than the shares of Common Stock to be
issued and sold upon settlement of the Purchase Contracts (as defined in the
Underwriting Agreement) and shares issued in the ordinary course pursuant to
employee benefit plans, non-employee director plans or the common stock
investment plan or options, warrants or rights outstanding on the date hereof,
Treasury PIES or Corporate PIES that may be created or recreated upon
substitution of pledged securities or Common Stock issuable upon early
settlement of the Corporate PIES or Treasury PIES) or sell or grant options,
warrants or rights with respect to any shares of Common Stock, securities
convertible into or exchangeable for Common Stock or substantially similar
securities (other than the grant of options, warrants or rights pursuant to
option plans existing on the date hereof), or (2) enter into any swap or other
derivatives transaction that transfers to another, in whole or in part, any of
the economic benefits or risks of ownership of such shares of Common Stock,
whether any such transaction described in clause (1) or (2) above is to be
settled by delivery of Common Stock or other securities, in cash or otherwise,
for a period of 90 days after the date of the Prospectus (as defined in the
Underwriting Agreement) offering; PROVIDED, HOWEVER, that, the restrictions set
forth above shall not apply to (i) sales of shares of Common Stock made to
satisfy loans incurred to finance the purchase of such shares of Common Stock,
if that satisfaction is required by the lender pursuant


                                      A-1



to margin regulations and (ii) charitable donations of shares of Common Stock
that are consistent with the prior years' practice.

         In furtherance of the foregoing, the Company and its transfer agent are
hereby authorized to decline to make any transfer of securities if such transfer
would constitute a violation or breach of this Lock-Up Letter Agreement.

         The undersigned understands that the Company and the Underwriters will
proceed with the Offering in reliance on this Lock-Up Letter Agreement. Whether
or not the Offering actually occurs depends on a number of factors, including
market conditions. Any Offering will only be made pursuant to an Underwriting
Agreement, the terms of which are subject to negotiation between the Company and
the Underwriters. In addition, it is understood that, if the Company notifies
you that it does not intend to proceed with the Offering, if the Underwriting
Agreement does not become effective or if the Underwriting Agreement (other than
the provisions thereof which survive termination) shall terminate or be
terminated prior to payment for and delivery of the Corporate PIES, the
undersigned will be released from our obligations under this Lock-Up Letter
Agreement.

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

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Lock-Up Letter Agreement and that,
upon request, the undersigned will execute any additional documents necessary in
connection with the enforcement hereof. Any obligations of the undersigned shall
be binding upon the heirs, personal representatives, successors and assigns of
the undersigned.

                                                Very truly yours,



                                                ----------------------------
                                                Name:
                                                Title:


                                      A-2



Dated:  November __, 2001

                                                                       ANNEX B

                 CONTENTS OF OPINIONS OF COUNSEL FOR THE COMPANY

         1. The Company and each of its Significant Subsidiaries have been duly
incorporated and are validly existing as corporations in good standing under the
laws of the State of Nevada, are duly qualified to do business and are in good
standing as foreign corporations in each jurisdiction in which their respective
ownership or lease of property or the conduct of their respective businesses
requires such qualification and have all corporate power and authority necessary
to own or hold their respective properties and conduct the businesses in which
they are engaged, except where the failure to so qualify or to be in good
standing would not have a Material Adverse Effect.

         2. The Company has all power and authority necessary to execute and
deliver each of the Transaction Agreements, to perform its obligations
thereunder and to issue the Securities; and the Company has duly authorized,
executed and delivered each of the Transaction Agreements.

         3. The execution, delivery and performance of the Transaction
Agreements, the issuance and sale of the Securities and the consummation by the
Company of the transactions contemplated thereby, including without limitation
the issuance, delivery and sale of the Securities, do not and will not (a)
conflict with or result in a breach or violation of any of the terms or
provisions of, or constitute a default under, any indenture, mortgage, deed of
trust, loan agreement or other agreement or instrument to which the Company or
any of its Significant Subsidiaries is a party or by which the Company or any of
its Significant Subsidiaries is bound or to which any of the properties or
assets of the Company or any of its Significant Subsidiaries is subject, which
would be reasonably likely to result in a Material Adverse Effect, (b) result in
any violation of the provisions of the charter or by-laws of the Company or any
of its Significant Subsidiaries, (c) result in any violation of any statute or
any order, rule or regulation of any court or governmental agency or body having
jurisdiction over the Company or any of its Significant Subsidiaries or any of
their respective properties or assets, which would be reasonably likely to
result in a Material Adverse Effect, or (d) require any material consent,
approval, authorization or order of, or filing or registration with, any such
court or governmental agency or body for the consummation of the Transactions or
the issuance and sale or exchange of the Securities, as the case may be, except
for (x) the registration of the Securities under the Securities Act, (y) the
qualification of the Indenture under the Trust Indenture Act and (z) such
consents, approvals, authorizations, registrations or qualifications as may be
required under the Exchange Act and applicable state securities laws in
connection with the purchase of the Corporate PIES (and the securities which are
components of the Corporate PIES as set forth above) by the Underwriters
pursuant to the Underwriting Agreement.

         4. Assuming due authorization, execution and delivery of the Purchase
Contract Agreement by the Purchase Contract Agent, the Purchase Contract
Agreement constitutes a legally valid and binding agreement of the Company,
enforceable against the Company in accordance with its terms, subject to the
effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, general equitable principles (whether considered in a proceeding in
equity or at law) and an implied covenant of good faith and fair dealing; the
Purchase Contract


                                      B-1



Agreement is not required to be qualified as an indenture under the Trust
Indenture Act; and the Purchase Contract Agreement conforms in all material
aspects to the description thereof contained in the Prospectus.

         5. The Corporate PIES, when duly executed and delivered by the Company
(assuming due execution by the Purchase Contract Agent as attorney-in-fact for
the holders thereof and due authentication by the Purchase Contract Agent) and,
upon payment therefor as set forth in the Underwriting Agreement, will be duly
and validly issued and outstanding, and will constitute valid and binding
obligations of the Company, entitled to the benefits of the Purchase Contract
Agreement and enforceable against the Company in accordance with their terms,
subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair
dealing; and the Corporate PIES will conform, when issued, in all material
respects to the description thereof contained in the Prospectus.

         6. The Treasury PIES, when duly executed and delivered by the Company
(assuming due execution by the Purchase Contract Agent as attorney-in-fact for
the holders thereof and due authentication by the Purchase Contract Agent) and,
if there is a substitution of the requisite number of Treasury Securities for
the applicable Senior Notes as set forth in the Prospectus Supplement, will be
duly and validly issued and outstanding, and will constitute valid and binding
obligations of the Company, entitled to the benefits of the Purchase Contract
Agreement and enforceable against the Company in accordance with their terms,
subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair
dealing; and the Treasury PIES will conform, when issued, to the description
thereof contained in the Prospectus.

         7. Assuming due authorization, execution and delivery of the Indenture
by the Trustee, the Indenture constitutes a legally valid and binding agreement
of the Company, enforceable against the Company in accordance with its terms,
subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair
dealing; the Indenture has been duly qualified under the Trust Indenture Act;
and the Indenture conforms in all material respects to the description thereof
contained in the Prospectus.

         8. The Senior Notes, when duly executed, authenticated, issued and
delivered as contemplated by the Indenture against payment of the agreed
consideration therefor, will be duly and validly issued and outstanding, and
will constitute legally valid and binding obligations of the Company, entitled
to the benefits of the Indenture and enforceable against the Company in
accordance with their terms, subject to the effects of bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other similar laws
relating to or affecting creditors' rights generally, general equitable
principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing; and the Senior Notes, when
issued,


                                      B-2



will conform in all material respects with the description thereof contained
in the Prospectus Supplement.

         9. Assuming due authorization, execution and delivery of the Pledge
Agreement by the Purchase Contract Agent, the Securities Intermediary and the
Collateral Agent, the Pledge Agreement constitutes a legally valid and binding
agreement of the Company, enforceable against the Company in accordance with its
terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered in
a proceeding in equity or at law) and an implied covenant of good faith and fair
dealing; and the Pledge Agreement conforms in all material respects to the
description thereof contained in the Prospectus.

         10. Assuming due authorization, execution and delivery of the
Remarketing Agreement by the Remarketing Agent, the Remarketing Agreement
constitutes a legally valid and binding agreement of the Company, enforceable
against the Company in accordance with its terms, subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, general
equitable principles (whether considered in a proceeding in equity or at law)
and an implied covenant of good faith and fair dealing, and except with respect
to the rights of indemnification and contribution under the Underwriting
Agreement, where enforcement hereof may be limited by federal or state
securities laws or the policies underlying such laws; and the Remarketing
Agreement conforms in all material respects to the description thereof contained
in the Prospectus.

         11. The provisions of the Pledge Agreement will be, on the First
Delivery Date, effective to create, in favor of the Collateral Agent for the
benefit of the Company, a valid security interest under the Uniform Commercial
Code as in effect on the date of such opinion in the State of New York (the "NEW
YORK UCC") in the Pledged Senior Notes, Applicable Ownership Interests (as
specified in clause (A) of the definition thereof in the Indenture) of the
Treasury Portfolio and Pledged Treasury Securities from time to time credited to
the Collateral Account in accordance with the Pledge Agreement. For purposes of
this opinion, capitalized terms used in this paragraph, which are not defined in
the Underwriting Agreement, shall have the meanings ascribed to such terms in
the Pledge Agreement.

         12. The unissued shares of Common Stock to be issued and sold by the
Company upon settlement of the Purchase Contracts have been duly authorized and
reserved for issuance and, when issued, sold and delivered, against payment, in
accordance with the provisions of the Purchase Contracts, will be duly and
validly issued, fully paid and non-assessable and will conform in all material
respects to the description thereof contained in the Prospectus.

         13. Except to the extent described in the Prospectus, there are no
preemptive or other rights to subscribe for or to purchase, nor is there any
restriction on the voting or transfer of, any of the Securities pursuant to the
Company's articles of incorporation or by-laws or any agreement or instrument,
except such preemptive or other rights and/or restrictions as relate to


                                      B-3



the transactions contemplated by the Stock Purchase Agreement, the Pledge
Agreement and the Indenture.

         14. The Registration Statement was declared effective under the
Securities Act, and the Indenture was qualified under the Trust Indenture Act at
10:00 a.m. on November 7, 2001, the Prospectus was filed with the Commission
pursuant to Rule 424(b)(1) under the Securities Act specified in such opinion on
the date specified therein; and no stop order suspending the effectiveness of
the Registration Statement has been issued and, to the best knowledge of such
counsel, no proceeding for that purpose is pending or threatened by the
Commission.

         15. The Registration Statement and the Prospectus and any further
amendments or supplements thereto made by the Company prior to such Delivery
Date, the Incorporated Documents and any further amendment or supplement to any
such incorporated document made by the Company prior to such Delivery Date
(other than the financial statements and related schedules therein, as to which
we express no opinion), when they became effective or were filed with the
Commission, as the case may be, complied as to form in all material respects
with the requirements of the Securities Act or the Exchange Act, as applicable,
and the Trust Indenture Act; and the Indenture conforms in all material respects
to the requirements of the Trust Indenture Act.

         16. The statements made in the Prospectus under the captions
"Description of Debt Securities," "Description of the Common Stock,"
"Description of Stock Purchase Contracts and Stock Purchase Units," "Prospectus
Supplement Summary--The Offering," "Description of the PIES, "Description of the
Purchase Contracts," "Certain Provisions of the Purchase Contracts, the Purchase
Contract Agreement and the Pledge Agreement," and "Description of the Senior
Notes," insofar as they purport to constitute summaries of certain terms of
documents referred to therein, and considered together, constitute accurate
summaries of the terms of such documents in all material respects.

         17. The statements in the Prospectus Supplement under the captions
"United States Federal Income Tax Consequences" and "Certain ERISA
Considerations," insofar as they purport to constitute summaries of matters of
United States federal statutes or regulations or legal conclusions with respect
thereto, constitute accurate summaries of the matters described therein in all
material respects.

         18. The Company is not, and will not be after the application of the
proceeds from the offering of the Corporate PIES, an "investment company" within
the meaning of and subject to regulation under the Investment Company Act of
1940, as amended.

         19. The Company is a "holding company" under the Holding Company Act,
but, pursuant to Section (3)(a)(1) of the Holding Company Act, is exempt from
all provisions of the Holding Company Act except Section 9(a)(2) thereof.

         20. To the best knowledge of such counsel, there are no contracts or
other documents which are required by the Securities Act to be described in the
Prospectus or filed as exhibits to the Registration Statement which have not
been so described or filed as required.


                                      B-4



         21. To the best knowledge of such counsel, after due inquiry, and
except as set forth in the Prospectus, there are no legal or governmental
proceedings pending to which the Company or any of its subsidiaries is a party
or of which any property or assets of the Company or any of its subsidiaries is
the subject which, if determined adversely to the Company or such subsidiary,
would be reasonably likely to result in a Material Adverse Effect; and, to the
best knowledge of such counsel, no such proceedings are overtly threatened or
contemplated by governmental authorities or threatened by others.

         22. To the best knowledge of such counsel, after due inquiry, and
except as set forth in the Prospectus, there are no contracts, agreements or
understandings between the Company and any person granting such person the right
to require the Company to file a registration statement under the Securities Act
with respect to any securities of the Company owned or to be owned by such
person or to require the Company to include such securities in the securities
registered pursuant to the Registration Statement or in any securities being
registered pursuant to any other registration statement filed by the Company
under the Securities Act.

         23. Nothing has come to the attention of such counsel, after due
inquiry, which lead such counsel to believe that the Registration Statement
(except for the financial statements and financial data included or incorporated
by reference therein, as to which such counsel need express no belief), as of
the Effective Date, contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary in order to
make the statements therein not misleading, or that the Prospectus (except as
stated above), as of the applicable Delivery Date, includes any untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

         The letter, dated as of Closing Time, of Deloitte & Touche LLP shall be
in agreed form and shall confirm that they are independent public accountants
within the meaning of the Securities Act and shall be further to the effect
that:

              (i) in their opinion the financial statements examined by them and
included in the Incorporated Documents comply as to form in all material
respects with the applicable accounting requirements of the Securities Act;

              (ii) they have performed the procedures specified by the American
Institute of Certified Public Accountants for a review of interim financial
information as described in Statement of Auditing Standards No. 71, Interim
Financial Information, on the unaudited financial statements included in the
Incorporated Documents;

              (iii) on the basis of the review referred to in clause (ii) above,
a reading of the latest available interim financial statements of the Company,
inquiries of officials of the Company who have responsibility for financial and
accounting matters and other specified procedures, nothing came to their
attention that caused them to believe that:

                   (A) the unaudited financial statements included in the
Incorporated Documents do not comply as to form in all material respects with
the applicable accounting requirements of the Securities Act or that any
material modifications should be made to such unaudited financial statements for
them to be in conformity with generally accepted accounting principles;

                   (B) at the date of the latest available balance sheet read by
such accountants, or at a subsequent specified date not more than three business
days prior to the date of such letter, there was any change in the capital stock
or any increase in long-term debt or any decreases in net current assets or
stockholders' equity of the Company and its consolidated subsidiaries as
compared with amounts shown on the latest balance sheet included in the
Incorporated Documents; or

                   (C) for the period from the closing date of the latest income
statement included in the Incorporated Documents to the closing date of the
latest available income statement read by such accountants, there were any
decreases, as compared with the corresponding period of the previous year and
with the period of corresponding length ended the date of the latest income
statement included in the Incorporated Documents, in consolidated operating
revenue, net income and basic and diluted net income per share;

increases or decreases which the Incorporated Documents disclose have occurred
or may occur or which are described in such letter;

              (iv) in addition to their examination referred to in their report
contained in the Incorporated Documents, they have carried out certain other
specified procedures, not constituting an audit, with respect to the dollar
amounts, percentages, ratios and other financial information, (in each case to
the extent that such dollar amounts, percentages and other financial
information, either directly or by analysis or computation, are derived from
general accounting records of the Company) which appear in the Company's Annual
