Item 1.  Description of Proposed Transaction

A.  Introduction
   
       This Application-Declaration relates to the separation (the "Spin-off")
of the former assets of Black Mountain Gas Company, formerly an Arizona
corporation ("BMG"), into a wholly-owned, first-tier subsidiary of Northern
States Power Company, a Minnesota corporation ("NSP").  NSP acquired BMG on July
24, 1998 pursuant to a Merger (the "Merger") in which BMG was merged into NSP
with NSP as the surviving corporation.  The Merger and the Spin-off are
collectively referred to as the "Transaction."  NSP is currently a
public-utility company and an exempt holding company pursuant to Section 3(a)(2)
of the Public Utility Holding Company Act of 1935 (the "Act") and owns all of
the common stock of Northern States Power Company, a Wisconsin corporation
("NSP-W"), which is also a public-utility company under the Act.  Prior to the
Merger, BMG was an Arizona public service corporation.
    
       The Transaction is expected to produce significant benefits to the
public, investors and consumers and will meet all applicable standards of the
Act.  Among other things, NSP and BMG believe that the Transaction offers
strategic and financial benefits to each company and their respective
shareholders.

       As discussed more fully at Item 3.D. below, NSP believes that, following
the consummation of the Transaction, it will continue to be a holding company
entitled to an exemption pursuant to Section 3(a)(2) of the Act because it will
continue to be predominantly a public-utility company and its operations as such
will remain confined to Minnesota, its state of incorporation, and states
contiguous thereto.
   
       The shareholders of the common stock of BMG approved the merger of BMG
with and into NSP at a special meeting of BMG's shareholders on May 21, 1998.
The Merger was approved by the Arizona Corporation Service Commission (the
"Arizona Commission"), the Minnesota Public Utilities Commission (the "Minnesota
Commission") and the North Dakota Public Service Commission (the "North Dakota
Commission").  In addition, prior to consummating the Spin-off, NSP will obtain
approval of the Spin-off from the Arizona Commission, the Minnesota Commission
and the North Dakota Commission.  NSP submitted applications for such approval
on January 19, 1999 with the North Dakota Commission, January 13, 1999 with the
Minnesota Commission and January 23, 1999, with the Arizona Commission.  The
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act") has expired.  Apart from the approval of the
Securities and Exchange Commission (the "Commission") under the Act, the
foregoing approvals are the only governmental approvals required for the
Transaction.  In order to permit timely consummation of the Transaction and the
realization of the substantial benefits it is expected to produce, NSP requests
that the Commission's review of this Application-Declaration commence and
proceed as expeditiously as practicable.
    

<PAGE>

       1.  General Request and Overview of Transaction
   
       Pursuant to Section 9(a)(2) and Section 10 of the Act, NSP requests that
the Commission:  (i) authorize the Spin-off of BMG as a wholly-owned, first-tier
subsidiary of NSP as described herein, and (ii) grant such other authorizations
as may be necessary in connection therewith.  NSP also requests an order under
Section 3(a)(2) of the Act declaring it exempt from all provisions of the Act
except Section 9(a)(2) following consummation of the Transaction which will
establish BMG as a direct wholly-owned subsidiary of NSP.(1)
    
   
       Pursuant to an Agreement and Plan of Merger, dated as of December 29,
1997 (the "Merger Agreement"), on July 24, 1998, BMG merged into NSP with NSP as
the surviving corporation.  A copy of the Merger Agreement is incorporated by
reference as Exhibit B-1.  Pursuant to the Merger Agreement, each issued and
outstanding share of common stock, no par value, of BMG ("BMG Common Stock")
(except shares owned by BMG as treasury stock) was canceled and converted into
the right to receive a fraction of a share of common stock, $2.50 par value, of
NSP ("NSP Common Stock") equal to the quotient (hereinafter, the "Exchange
Ratio") derived by dividing (A) $17,750,000 by (B) the product of (i) the volume
weighted average of the closing prices for NSP Common Stock on the New York
Stock Exchange for the twenty full trading days ending on the third full trading
day prior to July 24, 1998, the date the Merger became effective (the "Average
NSP Share Price") and (ii) the number of shares of BMG Common Stock issued and
outstanding immediately prior to July 24, 1998.  Pursuant to the Merger
Agreement an additional number of shares of NSP Common Stock equal to the
quotient derived by dividing $1,500,000 by the Average NSP Share Price was
placed in escrow to satisfy any indemnification claims of NSP under the Merger
Agreement.  Such additional shares, net of any indemnification claims, will be
distributed pro rata to the former holders of BMG Common Stock on or about July
24, 1999, the first anniversary of the closing of the Merger.  Following receipt
of the Commission's approval of the Spin-off pursuant to this
Application-Declaration, NSP will cause the assets of BMG to be transferred to a
newly-formed, wholly-owned, first-tier subsidiary of NSP.  The effect of such
transfer will be that BMG will become a wholly-owned subsidiary of NSP.
    
       Upon completion of the Transaction, NSP will directly own NSP-W, a
public utility company, and BMG, also a public utility company.  In addition to
owning NSP-W and BMG, NSP will continue to own all of its existing non-utility
subsidiaries upon consummation of the Transaction.  See Exhibit E-2 for the
corporate structure to be in effect upon consummation of the Transaction.
   
       If the Commission does not authorize the Spin-off and the relief
requested above, then NSP requests, in the alternative, an order under Section
3(a)(2) of the Act declaring it exempt from all provisions of the Act except
Section 9(a)(2).
    


- ---------------------------
(1)    Since completion of the initial step of the Transaction (i.e., the
Merger) on July 24, 1998, NSP's utility operations have included the operations
of BMG.

B.  Description of the Parties to the Transaction

       1.  General Description

               (a)  NSP
   
       NSP was incorporated under the laws of the State of Minnesota in 1909.
It is a public-utility company and a holding company exempt from regulation by
the Commission under the Act (except for Section 9(a)(2) thereof) pursuant to
Section 3(a)(2) of the Act and by order of the Commission in NORTHERN STATES
POWER COMPANY, Holding Co. Act Release No. 22334, 24 SEC Docket 405 (Dec. 23,
1981).  The Merger of NSP and BMG is a transitional combination and the intended
result of the contemporaneous steps of the Transaction is that NSP becomes the
holding company of a second public utility subsidiary.  This view is consistent
with the Commission's policy to look at "the final result" rather than "separate
and succeeding transactions" where such are "integral parts of a single plan and
purpose."  SEE, E.G., NATIONAL PROPANE CORP., Holding Co. Act Release No. 20684,
46 S.E.C. 1332, 1337-8 (Aug. 24, 1978); SEE ALSO ASS'N OF MASS CONSUMERS, INC.
V. S.E.C., 516 F.2d 711, 717 (D.C. Cir. 1975), CERT. DENIED 423 U.S. 1052
(1976).
    
   
       NSP is engaged primarily in the generation, transmission and
distribution of electricity throughout a 30,000 square mile service area.  NSP
also purchases, distributes and sells natural gas to retail customers, and
transports customer-owned gas, in approximately 118 communities within this
area.  NSP provides electric utility service in South Dakota and electric and
gas utility service in Minnesota and North Dakota.  Of the more than 2.5 million
people served by NSP, the majority are concentrated in the Minneapolis-St. Paul
metropolitan area.  In 1998, more than 73% of the electric retail revenue of NSP
was derived from sales in the Minneapolis-St. Paul metropolitan area and more
than 64% of its retail gas revenue was derived from sales in the St. Paul
metropolitan area.  As of December 31, 1998, NSP provided electric utility
service to approximately 1,240,000 customers and gas utility service to
approximately 385,000 customers.
    
   
       NSP owns all of the outstanding common stock of NSP-W, a Wisconsin
corporation, which is a public-utility company under the Act.  NSP-W is engaged
in the generation, transmission, and distribution of electricity to
approximately 210,400 retail customers in an area of approximately 18,900 square
miles in northwestern Wisconsin, to approximately 9,100 electric retail
customers in an area of approximately 300 square miles in the western portion of
the Upper Peninsula of Michigan, and to 10 wholesale customers in the same
general area.  NSP-W purchases, distributes and sells natural gas to retail
customers or transports customer-owned natural gas, in the same service
territory to approximately 78,000 customers in Wisconsin and 5,000 customers in
Michigan.  In 1998, NSP-W provided approximately 13% of NSP's consolidated
revenues.
    
       Retail sales rates, services and other aspects of NSP's retail
operations are subject to the jurisdiction of the Minnesota Commission, the
North Dakota Commission and the South Dakota Commission within their respective
states.  The Minnesota Commission also possesses regulatory authority over
aspects of NSP's financial activities including security issuances, property
transfers when the asset value is in excess of $100,000, mergers with other
utilities, and


                                          3
<PAGE>

transactions between NSP and affiliates.  In addition, the Minnesota Commission
reviews and approves NSP's electric resource and gas supply capacity plans for
meeting customers' future energy needs.  NSP-W is subject to regulation of
similar scope by the Public Service Commission of Wisconsin (the "Wisconsin
Commission") and the Michigan Public Service Commission (the "Michigan
Commission"), except that the Michigan Commission does not regulate NSP-W's
issuances of securities.  In addition, before facilities may be sited and built,
a state commission generally must certify the need for new generating plants and
transmission lines of designated capacities to be located within such state.

       Wholesale rates for electric energy sold in interstate commerce,
wheeling rates for energy transmission in interstate commerce, and certain other
activities of NSP and NSP-W (including its hydro-electric facilities) are
subject to the jurisdiction of the Federal Energy Regulatory Commission (the
"FERC").  The operation and construction of NSP's Prairie Island and Monticello
nuclear facilities are subject to regulation by the Nuclear Regulatory
Commission.

       Non-utility businesses conducted directly by NSP consist of:  (i) an
appliance warranty program for its residential customers, (ii) construction of
natural gas distribution systems for third parties (primarily end-users and
municipal gas systems), (iii) sale and installation of power quality
instruments, primarily to protect equipment of customers from electric surges,
(iv) sale of steam to industrial customers in NSP's service territory, and (v)
installation and maintenance of street lighting for municipalities and other
customers.

   
       While NSP-W is currently the only public-utility subsidiary of NSP 
under the Act, NSP has ten other directly-owned subsidiaries that are engaged 
in various non-utility businesses:  NSP Financing I, Viking Gas Transmission 
Company ("Viking"), Energy Masters International, Inc. ("EMI," formerly 
Cenerprise, Inc.), Eloigne Company ("Eloigne"), First Midwest Auto Park, Inc. 
("FMAP"), Reddy Kilowatt Corportion ("Reddy Kilowatt"), United Power & Land 
Company ("UP&L"), Seren Innovations, Inc. ("Seren"), Ultra Power 
Technologies, Inc. ("Ultra Power") and NRG Energy, Inc. ("NRG").  NSP-W has 
two wholly-owned subsidiaries, Clearwater Investments, Inc. ("Clearwater") 
and NSP Lands, Inc. ("NSP Lands") and a 75.86% owned subsidiary, Chippewa & 
Flambeau Improvement Company ("C&F").  The activities of these subsidiaries 
are more fully described under Item 1.B.4(a) below.  For the year-ended 
December 31, 1998, approximately 6% of NSP's consolidated operating revenues 
(before intercompany eliminations) and 15% of its consolidated net income 
were derived from the non-utility businesses.  As of December 31, 1998, 
approximately 21% of NSP's consolidated assets were invested in non-utility 
businesses.
    
   
       NSP Common Stock is listed on the New York Stock Exchange, Inc. ("NYSE")
and the Chicago and Pacific Stock Exchanges.  As of December 31, 1998, there
were 152,696,971 shares of NSP Common Stock and 1,050,000 shares of NSP
cumulative preferred stock outstanding.  NSP's principal executive office is
located at 414 Nicollet Mall, Minneapolis, Minnesota 55401.  NSP-W does not have
any preferred stock outstanding and all of its common stock is owned by NSP.

(2)    In the following table, Electric Utility revenues are the revenues
derived by NSP and NSP-W from their operations as an "electric utility company"
as defined in Section 2(a)(3) under the Act; Gas Utility revenues are the
revenues derived by NSP and NSP-W from their operations as a "gas utility
company" under Section 2(a)(4) of the Act; and Non-Utility Subsidiaries revenues
include all other revenues of consolidated subsidiaries of NSP.  These amounts
do not conform to NSP's consolidated financial reports, as NSP reports in its
consolidated financial statements:  (i) the revenues of its wholly-owned
regulated natural gas interstate pipeline (Viking Gas Transmission Company) as
part of Gas Utility revenues, (ii) the revenues of its other consolidated
subsidiaries as part of "Other Income (Deductions)" and (iii) the results of the
operations of its non-consolidated subsidiaries under "Equity in Earnings of
Unconsolidated Affiliates."

100 square miles in Maricopa County, Arizona, and providing propane gas
distribution to an area of approximately 20 square miles in Coconino County,
Arizona, pursuant to certificates of convenience and necessity issued by the
Arizona Commission.  As of the year ended December 31, 1998, BMG provided
utility services to 6,463 customers.  Most of its customers are residential.
Non-residential customers include two school districts, three resorts and
multiple light commercial customers.  As such, BMG is a "gas utility company" as
defined in Section 2(a)(4) of the Act.  BMG does not own, control or hold the
voting securities of any public-utility company or holding company under the Act
and, thus, it is not a "holding company" as defined under Section 2(a)(7) of the
Act.  BMG has no subsidiaries.  BMG is not subject to regulation under the
jurisdiction of the FERC.  The Company's rates charged to customers are
regulated by the Arizona Commission.
    
   
       BMG also provides non-utility services and bulk propane sales through
its Lake Powell Propane division.  Such non-utility services also include
appliance repair.  In 1998, revenues and net income from non-utility services
totaled $1.7 million and $84,000, respectively, representing 28% and 23% of
BMG's operating revenue and net income, respectively, for the year ended
December 31, 1998.
    
   
       BMG's total operating revenues for the years ended December 31, 1996,
1997, and 1998 were approximately $6.3 million, $6.2 million, and $6.3 million,
respectively.  For the same periods, BMG's net income was approximately
$975,000, $1.3 million, and $400,000 respectively.  BMG's net utility assets as
of December 31, 1997, and 1998 were approximately $10.3 million and $15.5
million, respectively.

       4.  Non-Utility Interests of NSP, NSP-W and BMG

               (a)  NSP and NSP-W

   
               NSP's non-utility activities are conducted through its ten 
direct, wholly-owned subsidiaries: NSP Financing I, NRG, Viking, Eloigne, 
EMI, Seren, Ultra Power, FMAP, Reddy Kilowatt and UP&L.  NSP-W has two 
wholly-owned non-utility subsidiaries, Clearwater and NSP Lands, and a 75.86% 
owned subsidiary, C&F.  NSP Financing I is a special purpose business trust 
formed for the purpose of issuing preferred securities.  NRG operates and has 
ownership interests in independent, non-regulated power and energy businesses 
in the United States and other countries.  Each of its power generation 
businesses is a qualifying cogeneration facility ("QF") under the Public 
Utility Regulatory Policies Act of 1978, an exempt wholesale generator 
("EWG") under Section 32 of the Act or a foreign utility company ("FUCO") 
under Section 33 of the Act. Viking owns and operates a 500 mile interstate 
natural gas pipeline providing gas transportation service to customers in the 
Upper Midwest from connections with three major pipelines in the United 
States and Canada.  Eloigne has ownership interests in affordable housing 
projects, principally within NSP's service territory.  EMI delivers natural 
gas and electric products and services to commercial and industrial 
customers, utilities, municipalities and energy marketers, and offers 
performance contracting to customers nationwide.  Seren was formed to pursue 
communication and data services businesses.  Ultra Power will market a 
proactive, non-destructive, power-cable testing technology.  FMAP owns and 
operates a parking garage located next to NSP's headquarters.  Reddy Kilowatt 
(formerly Cormorant Corporation) originally was established for the 
principal purpose of acquiring fuel resources and has historically engaged in 
oil, gas, coal lignite and uranium exploration. Recently, Reddy Kilowatt 
acquired the trademark and associated rights to the "Reddy Kilowatt" name and 
changed the name of Cormorant Corporation. UP&L owns and holds real property 
typically surrounding or adjacent to property owned and used by NSP in its 
regulated operations.  Clearwater was established to identify and develop 
affordable housing investment opportunities for NSP-W. NSP Lands was created 
to develop and sell land owned by NSP-W adjacent to a hydro-electric 
generating facility previously owned by NSP-W.  C&F was created in 1911 for 
the purpose of building, maintaining and operating dams and reservoirs in 
Wisconsin.
    
   
               Together, NSP's and NSP-W's non-utility subsidiaries and
investments constituted approximately 21% of NSP's consolidated assets as of
December 31, 1998.  NSP's and NSP-W's non-utility subsidiaries and investments
also provided approximately 6% of NSP's total revenues and approximately 15% of
NSP's consolidated net income for the year ended December 31, 1998.

               (b)  BMG
   
               BMG provides non-utility services such as appliance repair and
bulk propane sales through its Lake Powell Propane division.  Revenues and net
income from non-utility services represented 28% and 23% of BMG's operating
revenues and net income, respectively, for the year ended December 31, 1998.
    
C.  Description of Transaction and Statement as to Consideration

       1.  Background

       The business of BMG has grown steadily over the past five years, and
beginning in 1996 BMG discontinued its regular dividend in favor of re-investing
excess operating income to sustain and increase such growth.  In recognition of
BMG's need for access to additional capital, and to provide BMG shareholders
with liquidity in their investment, in mid-1997 BMG's Board of Directors (the
"BMG Board") engaged Principal Financial Securities, Inc. ("PFS"), to assist in
identifying sources of capital and potential merger partners for BMG.  Through
this process, PFS introduced BMG to a number of possible merger partners which
conducted their own due diligence investigations of BMG and provided preliminary
offers to acquire BMG, one of which was NSP.  In September 1997, Bernard C.
Ziegler, formerly Chief Executive Officer of The Ziegler Company, Inc. and a
Director of BMG, advised James J. Howard, Chairman, President and Chief
Executive Officer of NSP, that BMG was considering a possible sale or merger.

       In September 1997, NSP management requested and obtained a confidential
information memorandum on BMG prepared by PFS.  The confidential information
memorandum contained information on BMG's history, operations, financial results
and corporate structure.  The confidential information memorandum was also made
available to other parties interested in a possible acquisition of or merger
with BMG.  In addition to reviewing the confidential information memorandum, NSP
management conducted internal analyses of the benefits of a merger with BMG and
tested the financial assumptions in the confidential information memorandum.

       From October to December 1997, representatives of NSP visited BMG to
review its operations and performed preliminary due diligence. During these
visits representatives of NSP reviewed documents concerning BMG that were made
available to parties interested in an acquisition or merger.  Representatives of
NSP continued to test financial assumptions and constructed financial models
regarding BMG's potential growth.  Representatives of NSP also obtained
additional information from BMG management, including Thomas LeNeau, President
and Chief Executive Officer of BMG.

       In November 1997, NSP management briefed Mr. Howard regarding the
desirability of a merger with BMG.  Based on the briefing, Mr. Howard directed
NSP management to perform additional due diligence and prepare an offer.

       On November 17, 1997, NSP submitted a written offer to merge with BMG.


                                          13
<PAGE>

       In December 1997, NSP management, including Cynthia L. Lesher, President
of NSP-Gas, visited BMG to conduct an additional review of its operations and
perform further due diligence.  During this visit to BMG, NSP management met
with BMG management to discuss, among other things, a merger of the two
companies.  On December 5, 1997, NSP submitted a revised written offer to merge
with BMG.

       On December 17, 1997, NSP management presented the proposed Merger to
the NSP Board.  The NSP Board discussed the potential benefits to shareholders
of NSP and customers of NSP that could result from the proposed Merger and voted
to approve the Merger.

       On December 29, 1997, the Agreement and Plan of Merger between NSP and
BMG was executed.  On April 17, 1998, Amendment No. 1 to the Agreement and Plan
of Merger between NSP and BMG (providing for certain minor technical changes)
was executed.
   
       On May 21, 1998, BMG's shareholders approved the Merger.  On July 24,
1998, following receipt of necessary state regulatory approvals, BMG was merged
into NSP.
    
       BMG retained PFS to act as financial advisor in connection with the
Transaction.  PFS was selected by BMG based on PFS's experience, expertise and
familiarity with BMG and its businesses.  As a nationally recognized investment
banking firm, PFS is regularly engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, leveraged buyouts,
negotiated underwritings, competitive biddings, secondary distributions of
listed and unlisted securities, private placements and valuations for estate,
corporate and other purposes.

       Additional information regarding the background of the Transaction is
set forth in the Registration Statement on Form S-4 of NSP, which is filed as
Exhibit C-1 hereto (the "Registration Statement").

       2.  Merger Agreement
   
               The Merger Agreement provided for BMG to be merged with and into
NSP, with NSP as the surviving corporation.  Pursuant to the Merger Agreement,
each issued and outstanding share of BMG (except shares owned by BMG as treasury
stock) was canceled and converted into the right to receive a fraction of a
share of NSP Common Stock, determined in accordance with the Exchange Ratio.
Each issued and outstanding share of NSP Common Stock remained outstanding,
unchanged, as one share of NSP Common Stock.  The Merger Agreement is
incorporated by reference as Exhibit B-1.  Pursuant to the Merger Agreement, an
additional number of shares of NSP Common Stock equal to the quotient derived by
dividing $1,500,000 by the Average NSP Share Price was placed in escrow to
satisfy any indemnification claims of NSP under the Merger Agreement.  Such
additional shares, net of any indemnification claims, will be distributed pro
rata to the former holders of BMG Common, on or about July 24, 1999, the first
anniversary of the closing of the Merger.  Following receipt of Commission
approval pursuant to this Application-Declaration, NSP will cause the assets of
BMG to be transferred to a newly-formed, wholly-owned subsidiary of NSP.
    

                                          14
<PAGE>
   
       If any holder of BMG Common Stock was entitled to receive a number of
shares of NSP Common Stock that includes a fraction, then in lieu of a
fractional share, such holder is entitled to receive a cash payment based on a
formula agreed to in the Merger Agreement.  The Transaction is expected to be
tax-free to NSP and BMG shareholders (except as to fractional shares).
    
       The Transaction is designed to qualify as a tax-free reorganization
under Section 368(a) of the Internal Revenue Code of 1986, as amended.  NSP and
BMG believe the Transaction will be treated as a "pooling of interests" for
accounting purposes.
   
    
       3.  Management of NSP following the Transaction

               As a result of the Transaction, BMG will become a second
public-utility subsidiary of NSP.  Present utility operations of NSP and NSP-W
and the non-utility operations of NSP's other subsidiaries will be unaffected.
NSP will continue to be predominantly an operating public-utility, engaged as
such in the generation, transmission, and distribution of electricity and the
distribution of natural gas in the state of Minnesota, NSP's state of
incorporation, and the contiguous states of North Dakota and South Dakota.
Following the Transaction, there will be no change in the composition of the NSP
Board or in the executive management of NSP.  After the Transaction, BMG, as a
wholly-owned subsidiary of NSP, will continue to distribute natural gas in the
state of Arizona.  BMG will continue to maintain its headquarters at Cave Creek,
Arizona, and no significant changes to the operations of BMG are anticipated as
a result of the Transaction.

       4.  Related Agreements
   
       In connection with the Merger Agreement, NSP and BMG also entered into a
stock option agreement (the "Option Agreement") (Exhibit B-2 hereto) giving NSP
the right to acquire up to 181,386 shares of BMG Common Stock under specified
circumstances.  The Option Agreement terminated by its terms upon completion of
the Merger.
    
Item 2.  Fees, Commissions and Expenses

       The fees, commissions and expenses to be paid or incurred, directly or
indirectly, in connection with the Transaction, including the solicitation of
proxies by BMG, registration of securities of NSP under the Securities Act of
1933, and other related matters, are estimated as follows:

Item 3.  Applicable Statutory Provisions

       Sections 9(a)(2) and 10 of the Act are directly or indirectly applicable
to the proposed Transaction.  To the extent that other sections of the Act or
the Commission's rules thereunder are deemed to be applicable to the
Transaction, such sections and rules should be considered to be set forth in
this Item 3.

       Section 9(a)(2) of the Act makes it unlawful, without approval of the
Commission under Section 10, "for any person...to acquire, directly or
indirectly, any security of any public-utility company, if such person is an
affiliate...of such company and of any other public-utility or holding company,
or will by virtue of such acquisition become such an affiliate."  Under the
definition set forth in Section 2(a)(11) of the Act, an "affiliate" of a
specified company means "any person that directly or indirectly owns, controls,
or holds with power to vote, 5 per centum or more of the outstanding voting
securities of such specified company," and "any company 5 per centum or more of
whose outstanding voting securities are owned, controlled, or held with power to
vote, directly or indirectly, by such specified company...."
   
       NSP, NSP-W and BMG, are "public-utility companies" as defined in
Section 2(a)(5) of the Act.  Since NSP currently owns more than five percent of
the voting securities of NSP-W and, following the Spin-off and the consummation
of the Transaction, will acquire more than five percent of the voting securities
of BMG, NSP would appear to need the approval of the Commission for the Spin-off
under Section 9(a)(2) and 10 of the Act.  The statutory standards to be
considered by the Commission in evaluating the Transaction are set forth in
Sections 10(b), 10(c) and 10(f) of the Act.

                                          16
<PAGE>

       As set forth more fully below, the Transaction complies with all of the
applicable provisions of Section 10 of the Act and should be approved by the
Commission:

       -       The consideration to be paid in the Transaction is fair and
               reasonable;

       -       The Transaction will not create detrimental interlocking
               relations or concentration of control;

       -       The Transaction will not result in an unduly complicated capital
               structure for the NSP  system;

       -       The Transaction is in the public interest and the interests of
               investors and consumers;

       -       The Transaction is consistent with Sections 8 and 11 of the Act;

       -       The Transaction tends toward the economical and efficient
               development of an integrated public-utility system; and

       -       The Transaction will comply with all applicable state laws.

       Furthermore, this Transaction also provides an opportunity for the
Commission to follow certain of the interpretive recommendations made by the
Division of Investment Management (the "Division") in the report issued by the
Division in June 1995 entitled "The Regulation of Public Utility Holding
Companies" (the "1995 Report").  While the Transaction and the requests
contained in this Application-Declaration are well within the precedent of
transactions approved by the Commission as consistent with the Act prior to the
1995 Report and thus could be approved without any reference to the 1995 Report,
a number of the recommendations contained therein serve to strengthen the
Applicant's analysis and would facilitate the creation of a utility company
better able to compete in the rapidly evolving utility industry.  The Division's
overall recommendation that the Commission "act administratively to modernize
and simplify holding company regulation...and minimize regulatory overlap, while
protecting the interests of consumers and investors,"(4) should be used in
reviewing this Application-Declaration because, as demonstrated below, the
Transaction will benefit both consumers and shareholders of BMG and NSP and
because the state regulatory authorities with jurisdiction over this Transaction
will have approved it as in the public interest.

A.  Section 10(b)

       Section 10(b) provides that, if the requirements of Section 10(f) are
satisfied, the Commission shall approve an acquisition under Section 9(a)
unless:

               (1)    such acquisition will tend towards interlocking relations
               or the concentration of control of public-utility companies, of a
               kind or to an extent detrimental to the public interest or the
               interest of investors or consumers;

Exchange Commission, 1995 Report at 3.

               (2)    in the case of the acquisition of securities or utility
               assets, the consideration, including all fees, commissions, and
               other remuneration, to whomsoever paid, to be given, directly or
               indirectly, in connection with such acquisition is not reasonable
               or does not bear a fair relation to the sums invested in or the
               earning capacity of the utility assets to be acquired or the
               utility assets underlying the securities to be acquired; or

               (3)    such acquisition will unduly complicate the capital
               structure of the holding-company system of the applicant or will
               be detrimental to the public interest or the interest of
               investors or consumers or the proper functioning of such
               holding-company system.

       1.  Section 10(b)(1)
   
       Section 10(b)(1) requires a finding that control is "of a kind or to an
extent detrimental to the public interest or the interest of investors or
consumers."  The framers of the Act sought, through Section 10(b)(1) to avoid
"an excess of concentration and bigness" while preserving the "opportunities for
economies of scale, the elimination of duplicative facilities and activities,
the sharing of production capacity and reserves and generally more efficient
operations" afforded by certain combinations.  AMERICAN ELECTRIC POWER CO.,
INC., Holding Co. Act Release No. 20633, 46 S.E.C. 1299, 1309 (1978).  The
acquisition of the very small distribution system of BMG by NSP will not create
an "excess of concentration and bigness," but, as discussed in more detail
below, will afford BMG the opportunity to achieve the economies of scale and
efficiencies, particularly in the areas of management expertise and gas supply,
that the Act's framers intended to preserve for the benefit of investors and
consumers.
    
       2.  Section 10(b)(2)

       As noted above, the Commission may not approve the Transaction under
Section 10(b)(2) if it finds that the consideration to be paid in connection
with the combination, including all fees, commissions and other remuneration, is
"not reasonable or does not bear a fair relation to the sums invested in or the
earning capacity of...the utility assets underlying the securities to be
acquired...."

       NSP and BMG believe that the standards of Section 10(b)(2) regarding
consideration are satisfied in the present case for the following reasons.
   
       First, the Merger was a pure stock-for-stock exchange and qualifies for
treatment as a pooling of interests.  As set forth more fully at above Item
1.C.2, each share of BMG Common Stock was converted into the right to receive a
fraction of a share of NSP Common Stock in accordance with the Exchange Ratio,
and each share of NSP Common Stock will continue as a share of NSP Common Stock.
The Transaction will therefore involve no "acquisition adjustment" or other
write-up of the assets of NSP or BMG.
    
       Second, the Transaction was approved by the BMG Board and has been
submitted to, and approved by, the common shareholders of BMG.  As provided
under the Arizona Business

                                          18
<PAGE>
   
Corporation Act, the affirmative vote of a majority of the votes entitled to be
cast by the holders of the outstanding shares of BMG's Common Stock was required
for approval of the Merger.
    
       Third, the Exchange Ratio is the product of arms-length negotiations
between NSP and BMG and was approved by the BMG Board.  Such negotiations were
preceded by extensive due diligence, analysis and evaluation of the assets,
liabilities and business prospects of BMG.  See Item 1.C.1 of this
Application-Declaration and "Background of the Merger" at pages 18 and 19 of the
Registration Statement (Exhibit C-1 hereto).  As recognized by the Commission in
OHIO POWER CO., Holding Co. Act Release No. 16753, 44 S.E.C. 340, 346 (June 8,
1970), prices arrived at through arms-length negotiations are particularly
persuasive evidence that Section 10(b)(2) is satisfied.

       Finally, PFS, a nationally-recognized investment banking firm engaged by
BMG, has reviewed extensive information concerning BMG, analyzed the Exchange
Ratio employing a variety of valuation methodologies and opined that the
Exchange Ratio is fair to the holders of BMG Common Stock as of the date of the
Merger Agreement and as of the date the proxy statement/prospectus included in
the Registration Statement was mailed to the stockholders of BMG.  PFS's
analysis and opinion is described in detail on pages 20 to 22 of the
Registration Statement (Exhibit C-1 hereto).  The assistance of independent
consultants in setting consideration has been recognized by the Commission as
evidence that the requirements of Section 10(b)(2) have been met.  THE SOUTHERN
COMPANY; SV VENTURES, INC., Holding Co. Act Release No. 24579, 40 SEC Docket 350
(Feb. 12, 1988).

       In rendering its fairness opinion, PFS performed a number of analyses
relevant to the reasonableness of the Exchange Ratio and their relation to the
investment in, and earning capacity of, the utility assets of BMG.  PFS reviewed
the Merger Agreement, related documents and certain publicly available business
and financial information relating to BMG and NSP.  PFS also reviewed certain
other information, including financial projections provided to it by BMG and met
with management of BMG to discuss the business and prospects of BMG.

       PFS also considered certain financial data for businesses similar to BMG
and considered, to the extent publicly available, the financial terms of certain
other business combinations and other transactions which have recently been
effected. PFS also considered such other information, financial studies,
analyses and investigations and financial, economic and market criteria that PFS
deemed relevant.

       In light of PFS's opinion and an analysis of all relevant factors,
including the benefits that may be realized as a result of the Transaction, the
Exchange Ratio falls within the range of reasonableness, and the consideration
for the Transaction bears a fair relation to the sums invested in, and the
earning capacity of, the utility assets of BMG.

       Item 2 of this Application-Declaration sets forth the fees, commissions
and expenses in connection with the Transaction.  NSP and BMG believe that the
overall fees, commissions and expenses incurred and to be incurred in connection
with the Transaction are reasonable and fair relative to other transactions and
the anticipated benefits of the Transaction to the public, investors and
consumers, consistent with recent precedent and the standards of
Section 10(b)(2).


                                          19
<PAGE>

Furthermore, the investment banking fees of BMG reflect the competition in the
marketplace, in which investment banking firms actively compete with each other
to act as financial advisors to merger partners.

       3.  Section 10(b)(3)

       Section 10(b)(3) requires the Commission to determine whether the
Transaction will "unduly complicate the capital structure" of the NSP system or
will be "detrimental to the public interest or the interest of investors or
consumers or the proper functioning" of the NSP system.

       Capital structure:  The corporate capital structure of NSP after the
Transaction will not be unduly complicated and will be substantially similar to
the capital structure of NSP prior to the Transaction, and, because neither
NSP-W nor BMG will have any preferred stock outstanding, less complex than
capital structures approved by the Commission in other orders.  SEE, E.G.,
CENTERIOR ENERGY CORP., Holding Co. Act Release No. 24073, 35 SEC Docket 769
(April 26, 1986); MIDWEST RESOURCES, INC., ET AL., Holding Co. Act Release
No. 25159, 47 SEC Docket 252 (Sept. 26, 1990); CINERGY CORP., Holding Co. Act
Release No. 26146, 57 SEC Docket 2353 (Oct. 21, 1994).
   
       In the Transaction, the shareholders of BMG received NSP Common Stock.
NSP will own 100% of the common stock of NSP-W and BMG and there will be no
minority common stock interest remaining in either company.  Furthermore,
neither NSP-W nor BMG will have any preferred stock outstanding.  The existing
debt securities of NSP, NSP-W and BMG will remain outstanding without change.
The only voting securities of NSP which will be publicly held after the
Transaction will be NSP Common Stock and NSP preferred stock.  The only class of
voting securities of NSP direct subsidiaries will be common stock and, in each
case, all issued and outstanding shares of such common stock will be held by
NSP.
    
   
       Set forth below are summaries of the historical capital structures of
NSP and BMG as of December 31, 1997 (prior to the Merger), the combined capital
structure of NSP as of December 31, 1998, and the pro forma capital structure of
NSP and BMG following the Spin-off:

       As is evident from the above, the Transaction will have virtually no
effect on NSP's capital structure.
    
       Protected interests:  Section 10(b)(3) also requires the Commission to
determine whether the proposed combination will be detrimental to the public
interest, the interests of investors or consumers or the proper functioning of
the NSP system.  The combination of NSP and BMG is entirely consistent with the
proper functioning of the NSP holding company system.  Further, as

discussed in Item 3.B.2.(a), the combination will result in benefits to the
public and to consumers and investors of both companies and also will improve
the efficiency of the BMG system.  The Merger has been approved by the Minnesota
Commission, the North Dakota Commission and the Arizona Commission.  Moreover,
as noted by the Commission in ENTERGY CORPORATION ET AL., Holding Co. Act
Release No. 25952, 55 SEC Docket 2035, 2045 (Dec. 17, 1993), "concerns with
respect to investors' interests have been largely addressed by developments in
the federal securities laws and the securities market themselves."  NSP is and
will remain a reporting company subject to the continuous disclosure
requirements of the 1934 Act following the completion of the Transaction.  The
various reports previously filed by NSP under the 1934 Act contain readily
available information concerning the Transaction.  For these reasons, the
Applicant believes that the Transaction will be in the public interest and the
interest of investors and consumers, and will not be detrimental to the proper
functioning of the resulting holding company system.
    
B.  Section 10(c)

       Section 10(c) of the Act provides that, notwithstanding the provisions
of Section 10(b), the Commission shall not approve:

       (1)     an acquisition of securities or utility assets, or of any other
               interest, which is unlawful under the provisions of Section 8 or
               is detrimental to the carrying out of the provisions of Section
               11(7); or

       (2)     the acquisition of securities or utility assets of a
               public-utility or holding company unless the Commission finds 
               that such acquisition will serve the public interest by tending
               towards the economical and the efficient development of an 
               integrated public utility system....

       1.  Section 10(c)(1)

               (a) Compliance With Section 8
   
       Section 8 prohibits registered holding companies from acquiring
properties which would result in combined gas and electric operations in the
same area without the authorization of the appropriate state commission, where
state law prohibits or requires authorization for such combined operations.
Section 8 applies only to registered systems and thus, by its terms, is not
applicable to NSP, BMG, the Merger or the Transaction.  Moreover, the Merger
occurred only after authorizations of the Arizona Commission, the Minnesota
Commission and the North Dakota Commission were granted.  The Spin-off will
receive approvals from the Arizona Commission, the Minnesota Commission and the
North Dakota Commission, and, thus, the Spin-off will not be consummated until
such authorizations have been obtained.  Accordingly,
    

- ---------------------------
(7)    By their terms, Sections 8 and 11 only apply to registered holding
       companies and are therefore inapplicable at present to NSP or BMG, since
       neither is now a registered holding company.  Also, under the present
       transaction structure, NSP will remain an exempt holding company after
       consummation of the Transaction.


                                          22
<PAGE>

the Transaction will not be unlawful under Section 8, and thus that portion of
Section 10(c)(1) relating to Section 8 of the Act is satisfied.

               (b)  No Detriment to the Carrying Out of Section 11

       Section 11 of the Act sets forth the integration and simplification
requirements of the Act applicable to registered holding company systems.
Section 11 requires the Commission to take action with respect to registered
holding company systems that will (1) limit the operations of each registered
holding company system to a single integrated public-utility system, certain
"functionally related" businesses, and one or more additional integrated public
utility systems meeting certain requirements (Section 11(b)(1)); and (2) ensure
that the registered system has a simplified corporate structure without undue or
unnecessary complications or inequitable distribution of voting power
(Section 11(b)(2)).

       Section 11 applies only to registered holding companies.  In a
proceeding under Section 9(a)(2) where the resulting system would be exempt, as
well as in proceedings under Section 3 for the grant of an exemption, compliance
with the standards of Section 11 is not required.(8)  As the Commission has
stated in approving an exempt company's application under both Section 9(a)(2)
and Section 3, "Section 10(c)(1)'s requirement that the acquisition not be
'detrimental' to carrying out the provisions of Section 11 does not mandate that
the latter section's integration requirements be met."(9)

       Instead, in applying Section 10(c)(1) to an exempt system, the
Commission looks to whether the acquisition would be detrimental to the public
interest.  With respect to combination gas and electric systems, which could
raise integration issues under Section 11 for registered holding companies, the
Commission approves applications for exempt systems where it finds generally
that the other requirements of Section 10 have been met and that the appropriate
state commission has acted favorably.  For example, in DOMINION RESOURCES, INC.,
the Commission approved the acquisition by a combination company of a small gas
utility.(10)  In so doing, the Commission explicitly recognized that the limits
in Section 11 were inapplicable given the applicant's exemption from
registration.  With respect to the extension of the gas operations of the
combined system, the Commission took pains to state that "the only question" was
whether that extension would be "detrimental to the public interest or in the
interest of investors or consumers" within the language of Sections 10(b)(1) and
10(b)(3).(11)  The Commission went on

to state that Section 10(c)(1) of the Act would bring Section 11(b)(1) into
consideration only if Dominion Resources were not entitled to an exemption under
Rule 2 of the Act.(12)  Furthermore, the Commission cited favorably its decision
in WPL HOLDINGS INC., Holding Co. Act Release No. 24590, 40 SEC Docket 634 (Feb.
26, 1988), for the proposition that where there is evidence of effective state
regulation over the activities of a combination company otherwise entitled to an
exemption under Section 3(a), the Commission need not find that permitting
retention of combined operations would be detrimental to the public interest.
In the present circumstances, following the Spin-off and consummation of the
Transaction, NSP would be entitled to continue its Section 3(a)(2) exemption
pursuant to Rule 2.
   
       Based on the foregoing precedent, the Transaction satisfies the
requirements of Section 10(c)(1) and will promote the public interest of
creating stronger competitors in the evolving utility industry.  First, as
discussed previously and as will be discussed below, NSP's acquisition of BMG
will meet the standards set forth in Section 10, including the requirement that
the Transaction tend toward the efficient and economical development of an
integrated public-utility system.  In brief, the combination will produce an
integrated electric utility system that substantially overlaps an integrated gas
utility system and that will reap the many benefits available from combined
resources while preserving local control and state regulation, and while also
enhancing, rather than decreasing, competition in the states served by NSP,
NSP-W and BMG as well as nationwide.  Particularly, as detailed in Item 3.B.2(a)
below, as a result of the Transaction, BMG will be financially stronger, more
technologically advanced and possess more purchasing power, and its investors
and customers in Arizona will benefit from BMG's improved competitive position.
Second, as previously discussed, the Arizona Commission and the state
commissions which regulate NSP have addressed and ruled favorably on the issues
raised by the Merger.  Finally, the Applicant believes that the Transaction
poses no other concerns to the public interest or the interest of investors or
consumers than those already addressed or that are likely to arise in the state
proceedings.  Indeed, BMG's investors, its customers in Arizona and the public,
generally, will benefit from the economies and efficiencies that will make BMG a
more competitive gas utility company following the Transaction.  For these
reasons, no adverse finding is required under Section 10(c)(1).
    
       2.  Section 10 (c)(2)

       Because the Transaction is expected to result in economies and
efficiencies for the BMG system, it will tend toward the economical and
efficient development of an integrated public utility system, thereby serving
the public interest, as required by Section 10(c)(2) of the Act.  "The
Commission has previously determined ... that where a holding company will be
exempt from registration under section 3 of the Act following an acquisition of
non-integrating utility

assets, it suffices for purposes of section 10(c)(2) to find benefits to one
integrated system."(13)  The Transaction clearly satisfies this requirement as
it will produce benefits to the gas utility businesses of NSP, NSP-W and BMG.
These include joint procurement of gas and other supplies, sharing of NSP's
extensive technological, operational, gas purchasing and other expertise,
enhanced computer services, and access to NSP's management, legal, financial,
accounting and consulting services.

               (a)  Efficiencies and Economies

               The Transaction will produce economies and efficiencies more than
sufficient to satisfy the standards of Section 10(c)(2) of the Act.  Although
some of the anticipated economies and efficiencies will be fully realizable only
in the longer term, they are properly considered in determining whether the
standards of Section 10(c)(2) have been met.  SEE IN THE MATTER OF AMERICAN
ELECTRIC POWER CO., SUPRA at 1320-1321.  Some potential benefits cannot be
precisely estimated, nevertheless they too are entitled to be considered.
"[S]pecific dollar forecasts of future savings are not necessarily required; a
demonstrated potential for economies will suffice even when these are not
precisely quantifiable."  CENTERIOR ENERGY CORP., SUPRA at 775, citing IN THE
MATTER OF AMERICAN ELECTRIC POWER CO., SUPRA.

       The Transaction is expected to yield several types of economies and
efficiencies, which are identified by area below: (1) corporate and
administration benefits, (2) management and operational efficiencies,
(3) purchasing economies (gas supply and others), (4) enhanced technology and
computer services.  These categories are described in greater detail below.

       Corporate and Administrative Efficiencies:  BMG will benefit from NSP's
breadth of management and operations expertise, which will enable BMG to develop
an efficient system in an efficient manner.  Moreover, NSP and BMG can achieve
savings through the consolidation of overlapping or duplicative programs and
expenses.  For example, coordinated marketing planning will occur to the benefit
of BMG as it can take advantage of NSP's expertise, efficiencies and economies
of advertising, promotions, direct mailings and other marketing programs.  Other
specific areas in which economies, efficiencies and savings are expected to
occur include information systems, professional services, benefits, insurance,
and shareholder services.

       Management and Operational Efficiencies:  NSP's management is highly
trained and experienced in the gas industry and will bring their technological,
operations, gas purchasing, customer service and regulatory expertise to BMG.
In addition to significant management enhancements, NSP will provide BMG with
regular legal, financial, accounting and consulting services.

       Purchasing Economies (Gas Supply and Others):  NSP and BMG will realize
economies through the combined procurement of material and supplies, as well as
from economies of scale from increased purchasing power over service providers.
Because NSP and BMG will continue to purchase from common sources of gas supply,
it is anticipated that areas of savings will result

from optimizing transportation capacity on various pipelines, shortening storage
withdrawal periods to provide greater peak day delivery and shifting purchases
among various producers.

       Enhanced Technology and Computer Services:  BMG will benefit from NSP's
utilization of state of the art technology and methods for providing gas
distribution services.  NSP will provide BMG with access to enhanced computer
services to handle all customer-related information needs, including account
information and gas consumption monitoring.  BMG will also be able to use NSP's
automated billing services.
   
       The Commission recently determined that benefits in the area of gas
supply, increased purchasing power and the ability to utilize the expertise and
resources available from public utility affiliates and other affiliates was
sufficient to satisfy Section 10(c)(2).(14)  These are precisely the types of
benefits that are expected to be realized by BMG.
    
               (b)  Integrated Public Utility System

       Because Section 2(a)(29) specifies separate definitions for gas and
electric systems, the Commission has historically taken the position that gas
and electric properties together cannot constitute a single integrated
public-utility system.(15)  However, Commission authority is equally clear that
Section 10(c)(2) does not limit Commission approval to acquisitions resulting in
only one integrated system.  "[W]e have indicated in the past that acquisitions
may be approved even if the combined system will not be a single integrated
system.  Section 10(c)(2) requires only that the acquisition tend 'towards the
economical and the efficient development of AN (emphasis in the original)
integrated public-utility system.'"(16)

       In this case, the Transaction will tend toward the economical and
efficient development of the integrated electric utility system of NSP and NSP-W
and an integrated gas utility system of NSP, NSP-W and BMG.

                      (i)  Electrical System

       As applied to electric utility companies, the term "integrated public
utility system" is defined in Section 2(a)(29)(A) of the Act as:

       a system consisting of one or more units of generating plants and/or
       transmission lines and/or distributing facilities, whose utility assets,
       whether owned by one or more electric utility companies, are physically
       interconnected or capable of physical interconnection and which under
       normal conditions may be economically operated as a single
       interconnected and coordinated system confined in its operations to a
       single area or region, in one or more states, not so large as to impair
       (considering the state of the art and the area or region affected) the
       advantage of localized management, efficient operation, and the
       effectiveness of regulation.

On the basis of this statutory definition, the Commission has established four
standards that must be met before the Commission will find that an integrated
electric system will result from a proposed acquisition of securities:

       (1)     the utility assets of the system are physically interconnected or
       capable of physical interconnection;

       (2)     the utility assets, under normal conditions, may be economically
       operated as a single interconnected and coordinated system;

       (3)     the system must be confined in its operations to a single area or
       region; and

       (4)     the system must not be so large as to impair (considering the
       state of the art and the area or region affected) the advantages of
       localized management, efficient operation, and the effectiveness of
       regulation.

IN RE ELECTRIC ENERGY, INC., et al., 38 SEC 658, 668 (1958)).  In the 1995
Report, the Division recommended that the Commission "respond realistically to
the changes in the utility industry and interpret more flexibly each piece of
the integration requirement."(17)  The Transaction satisfies all four of these
requirements.

       First, the Transaction will not change the electric utility system of
NSP, and the Commission has previously determined that the NSP system was an
integrated system.(18)  Moreover, NSP and NSP-W are already physically
interconnected through numerous transmission lines that they own, including one
345 Kv transmission line, two 115 Kv transmission lines and two 69 Kv
transmission lines.

(18)   NORTHERN STATES POWER COMPANY, Holding Co. Act Release No. 22334 (In
       discussing the integration of the electric system of Lake Superior
       District Power Company into the NSP system, the Commission stated, "The
       principal electric system of Northern States in southern Minnesota and
       northwestern Wisconsin, centering in Minneapolis, and the electric
       system of Lake Superior are integrated."

                                          27
<PAGE>

       Second, NSP and NSP-W will be economically operated as a single
interconnected and coordinated system.  The electric operations of NSP and NSP-W
are fully integrated and all generating units are centrally dispatched by NSP.

       Third, this single integrated system will operate in a single area or
region, covering portions of Minnesota, Wisconsin, Michigan, North Dakota and
South Dakota.  In the 1995 Report, the division stated that the evaluation of
the "single area or region" portion of the integration requirement "should be
made . . . in light of the effect of technological advances on the ability to
transmit electric energy economically over longer distances, and other
developments in the industry, such as brokers and marketers, that affect the
concept of geographic integration."(19)

       Fourth, the system is not so large as to impair the advantages of
localized management, efficient operations, and the effectiveness of regulation.
The Commission's past decisions on "localized management" show that the
Transaction fully preserves the advantage of localized management.  In these
cases, the Commission has evaluated localized management in terms of:  (i)
responsiveness to local needs, see AMERICAN ELECTRIC POWER CO., Fed. Sec. L.
Rep. PARA81,647 at 80,602 (1978) (advantages of localized management evaluated
in terms of whether an enlarged system could be "responsive to local needs"),
GENERAL PUBLIC UTILITIES CORP., 37 SEC 28, 36 (1956) (localized management
evaluated in terms of "local problems and matters involving relations with
consumers"); (ii) whether management and directors were drawn from local
utilities, see CENTERIOR ENERGY CORP., SUPRA (advantages of localized management
would not be compromised by the affiliation of two electric utilities under a
new holding company because the new holding company's management [would be]
drawn from the present management" of the two utilities); NORTHEAST UTILITIES,
Holding Co. Act Release No. 25221, 47 SEC Docket 1270 (Dec. 21, 1990)
(advantages of localized management would be preserved in part because the board
of New Hampshire Utility, which was to be acquired by an out-of-state holding
company, included "four New Hampshire residents"); (iii) the preservation of
corporate identities, see NORTHEAST UTILITIES, SUPRA (utilities "will be
maintained as separate New Hampshire corporations . . . [t]herefore the
advantages of localized management will be preserved"); COLUMBIA GAS SYSTEM,
INC., Holding Co. Act Release No. 24599, 40 SEC Docket 654 (March 15, 1988)
(benefits of local management maintained where the utility to be added would be
a separate subsidiary); and (iv) the ease of communications, see AMERICAN
ELECTRIC POWER CO., Fed. Sec. L. Rep PARA 81,647 at 80,602 (1978) (distance of
corporate headquarters from local management was a "less important factor in
determining what is in the public interest" given the "present-day" ease of
communications and transportation").

       The Transaction satisfies all of these factors.  NSP and NSP-W will
continue to operate through numerous regional offices with local service
personnel and line crews available to respond to customers' needs.  After the
Transaction, NSP and NSP-W will maintain their current headquarters for the
areas they presently serve.

       Finally, the NSP system will not impair the effectiveness of state
regulation.  NSP and NSP-W will continue their separate existence as before and
their utility operations will remain

subject to the same regulatory authorities by which they are presently
regulated, namely the MPUC, PSCW, MPSC, NDPUC, SDPUC and the FERC.  This
Transaction will not be consummated unless all required regulatory approvals are
obtained.

                      (ii)  Gas Utility System

       Section 2(a)(29)(B) defines an "integrated public utility system" as
applied to gas utility companies as:

       a system consisting of one or more gas utility companies which are so
       located and related that substantial economies may be effectuated by
       being operated as a single coordinated system confined in its operation
       to a single area or region, in one or more States, not so large as to
       impair (considering the state of the art and the area or region
       affected) the advantages of localized management, efficient operation,
       and the effectiveness of regulation:  Provided, that gas utility
       companies deriving natural gas from a common source of supply may be
       deemed to be included in a single area or region.
   
       As indicated above, in the 1995 Report, the Division recommended
flexibility in the interpretation of the integration requirement.  In
particular, the Division stated that it believed that the Commission "must adopt
a more flexible interpretation of the geographic and physical integration
standards, with more emphasis on whether an acquisition will be economical and
subject to effective regulation."(20)  The Division also believed it
"appropriate to interpret the 'single area or region' requirement flexibly
recognizing technological advances, consistent with the purposes and provisions
of the Act."(21)  Subsequently, in SEMPRA ENERGY, the Commission stated, "we
have taken notice of developments that have occurred in the gas industry, and
have interpreted the Act and analyzed proposal transactions in light of these
changed and changing circumstances."(22)
    
       NSP's acquisition of BMG, and the subsequent establishment of BMG as a
first tier subsidiary of NSP, will satisfy the integration standard set forth in
Section 2(a)(29)(B) of the Act as NSP, NSP-W and BMG will constitute a system so
located and related that substantial economies may be effectuated by their
operation as a single coordinated system confined in its operation to a single
area or region not so large as to impair the advantages of localized management,
efficient operation, and the effectiveness of regulation.   The Transaction will
also result in economies and efficiencies accruing to the benefit of NSP, NSP-W,
BMG, their shareholders and customers and their integrated system and thus
should be approved by the Commission.

       First, both the Commission's limited precedent and current technological
realities indicate that the combined NSP, NSP-W and BMG gas utility system will
operate as a

coordinated system confined in its operation to a single area or region because
it will derive natural gas from common sources of supply.  The Commission has
not traditionally required that the pipeline facilities of an integrated system
be physically interconnected,(23) and instead has looked to such issues as from
whom the distribution companies within the system receive much, although not
all, of their gas supply.(24)  The Commission also has considered obtaining gas
from a common pipeline (25) as well as from different pipelines when the gas
originates from the same gas field in determining a common source of supply.(26)
Since the time of most of these decisions, the state of the art in the industry
has developed to allow efficient operation of systems whose gas supplies derive
from many sources.(27)  Furthermore, the fact that Minnesota and Arizona are not
contiguous does not mean that the NSP system will not "be confined in its
operation to a single area or region."  The Commission has previously found
"utility properties to lie in a single area within the meaning of the Act
despite intervening territory."(28)  In SEMPRA ENERGY, the Commission reiterated
that "it is appropriate to treat gas systems as being in a 'single area or
region' when doing so does not undercut the policies of the Act," and held that
the distances between Sempra and its North Carolina subsidiary would not
undercut the policies of the Act though such distances were significantly
greater than the distances considered in MCN.(29)

       While the NSP and BMG gas systems are not physically interconnected,
they will functionally perform as a coordinated system through the purchase of
natural gas from common sources of supply (i.e., the Andarko and Permian
basins), and delivery through integrated interstate pipelines (all of which are
open access transportation only pipelines under FERC order 636).  This
coordination will result in greater efficiency.

       After the Transaction, it is anticipated that gas purchasing economic
efficiencies can be achieved by having NSP's gas department, which procures gas
for NSP and NSP-W, meet the gas purchasing needs of BMG as well.(30)  Thus, some
of each company's gas supply will be handled by the same entity and on a
coordinated basis. Although these gas purchases for BMG will be made on an
economic basis and not with the main goal of ensuring a common source of supply,
given economies of scale and the past practice by the same purchasers, it can be
expected that each of the three companies will continue to purchase significant
amounts of their respective gas supply from the same fields and that much of the
rest of their respective gas supply will travel through the same pipelines even
if it is not from the same field.  As noted above, NSP and BMG will functionally
perform as a coordinated system through the purchase of natural gas from common
sources of supply and the delivery of such gas, through integrated interstate
gas pipelines, to satisfy the "common source of supply" requirement of Section
2(a)(29)(B) of the Act.

       Moreover, the combination of the NSP, NSP-W and BMG systems will tend
toward the economic and efficient development of a coordinated gas system in
that there will be centralized computer and customer service systems, marketing
and operations planning and consulting between the three companies after the
Transaction.  Improved technology and centralized computer services for customer
services and centralized planning will occur to the benefit of BMG and its
customers.

       Significant day-to-day centralization between BMG and NSP will occur via
NSP's computer information system (the "NSP System").  The NSP System handles
all customer-related information needs, including account information and gas
consumption monitoring.  The NSP System personnel will provide frequent
consulting services to BMG's personnel on how to operate a link with the NSP
System and how to handle other customer service related matters.

       Finally, the gas utility system resulting after consummation of the
Transaction will also meet the requirement that it be "not so large as to impair
(considering the state of the art and the area or region affected) the
advantages of localized management, efficient operation and the effectiveness of
regulation."  IN THE MATTER OF AMERICAN NATURAL GAS COMPANY, Holding Co. Act

- ------------------------
(30)   In SEMPRA ENERGY, SUPRA note 14, the Commission found that a single
       coordinated system would exist where Sempra's North Carolina subsidiary
       could coordinate its purchase of gas in the San Juan and Permian Basins
       with affiliate companies through Sempra Trading, which would also
       coordinate gas transportation and storage arrangements.  Similarly, in
       MCN CORPORATION, SUPRA note 27, the Commission determined that a single
       coordinated system existed where MCN stated that its energy trading
       subsidiary intended to purchase gas supply for the new gas utility, to
       the extent it could do so reliably and economically; however, the gas
       utility would continue to have the option to purchase a part of its gas
       supply from other marketers if it could do so more efficiently.

Release No. 15620 (Dec. 12, 1966), the Commission found that the American
Natural System would meet the above requirement after its acquisition of an
Indiana gas utility as:

               Although American Natural will provide certain central
               facilities, equipment and personnel ... Central Indiana will
               retain its own local management and board of directors, a
               majority of whom will be residents of Indiana.  Central Indiana
               will continue to be subject to regulation by the Public Service
               Commission of Indiana.(31)
   
It is currently contemplated that localized management of BMG will be preserved.
Following the Transaction, there will be no significant change in the senior
management or board of directors of NSP and NSP-W.  While, as discussed above,
BMG will receive a number of centralized services and benefits from NSP, BMG's
headquarters will remain in Arizona, BMG will be operated on a day-to-day basis
by its local management, and BMG will remain locally regulated by the Arizona
Commission.  No significant change in management or operations of BMG will occur
as a result of the Transaction.  NSP will remain subject to the regulation of
the Minnesota Commission in the State of Minnesota, the North Dakota Commission
in the State of North Dakota and the South Dakota Commission in South Dakota.
NSP-W will remain subject to the regulation of the Wisconsin Commission.  Thus,
each of NSP, NSP-W and BMG will be locally operated and locally regulated, and
each will have the economic advantage of certain centralized services after the
Transaction.  From a regulatory standpoint, there will be no impairment of
regulatory effectiveness.(32)  The Arizona, Minnesota, and Wisconsin commissions
are already regulating multi-jurisdictional gas utilities as several other gas
utilities currently operate in several states, and, indeed, NSP and NSP-W
currently operate gas utilities in multiple states.
    
       For all of the reasons discussed above, NSP's ownership of BMG will
satisfy the integration requirements of Section 2(A)(29)(B).

C.  Section 10(f)

       Section 10(f) provides that:

       The Commission shall not approve any acquisition as to which an
       application is made under this section unless it appears to the
       satisfaction of the Commission that such State laws as may apply in
       respect of such acquisition have been complied with, except where the
       Commission finds that compliance with such State laws would be
       detrimental to the carrying out of the provisions of section 11.

       Board of Directors will consist of, among others, senior members of

       managed and operated as a business unit with autonomy.")

(32)   In SEMPRA ENERGY, SUPRA, note 14, the Commission similarly determined
       that the effectiveness of local regulation would not be impaired when a
       California gas utility holding company acquired a North Carolina gas
       utility.

As described below under Item 4, and as evidenced by the filings before the
Arizona Commission, Minnesota Commission, and North Dakota Commission, NSP and
BMG intend to comply with all applicable state laws related to the Transaction.

D.  Section 3(a)(2)
   
       In connection with the request under Section 10 of the Act, NSP requests
that the Commission issue an order under Section 3(a)(2) declaring that NSP will
be exempt from all provisions of the Act except Section 9(a)(2) following
completion of the Transaction.  Section 3(a)(2) of the Act provides that the
Commission may issue the above-requested order to a holding company, if:
    
               such holding company is predominantly a public-utility company
               whose operations as such do not extend beyond the State in which
               it is organized and States contiguous thereto.

Upon consummation of the Transaction, BMG and NSP-W will be direct wholly-owned
subsidiaries of NSP, and NSP will be predominantly a public-utility company
operating as such in Minnesota, its state of incorporation, and states
contiguous to Minnesota (North Dakota and South Dakota).
   
       With regard to whether a company operates "predominantly" as a
public-utility, the Commission has often considered factors indicative of the
relative size of the utility operations of the holding company compared to the
utility operations of its subsidiaries with most significance given to gross
revenues.(33)  Generally, the Commission has granted exemptions where the ratio
of the subsidiary's gross utility revenues to those of its parent was not more
than approximately 25%.(34)  Recently in HOUSTON INDUSTRIES INCORPORATED, ET
AL.,(35) the Commission granted an exemption to Houston Industries Incorporated,
notwithstanding the fact that its subsidiary, NorAm Energy Corp., had utility
operating revenues which were 52.5% of those of Houston Industries Incorporated.
For the year ended December 31, 1998, the combined utility operating revenues of
NSP-W and BMG were 15% of the utility operating revenues of NSP, substantially
lower than the ratios in prior cases where exemptions were granted.  Based on
the foregoing, there is no question that NSP is predominantly a public-utility
company.
    
   
       Furthermore, as previously discussed, NSP's operations as a
public-utility will be confined to Minnesota, its state of incorporation, and
states contiguous thereto, North Dakota and South Dakota.  As to BMG's
operations in the noncontiguous state of Arizona, Section 3(a)(2) does not
require geographic contiguity as to the operations of subsidiaries.  Thus, the
location of

BMG's operations after the Transaction is not an issue.(36)  In addition to
being consistent with Commission precedent, this view is also consistent with
the Commission's suggestion in the 1995 Report that geographic requirements for
an integrated public-utility should be flexibly interpreted, as "the relevance
of physical and geographic integration to a sound public-utility industry has
diminished."(37)
   
       In the event that the Commission does not issue an order approving the
Transaction under Section 10 of the Act, then NSP requests that the Commission
issue an order under Section 3(a)(2) declaring that NSP (which will include the
operations of BMG if the Spin-off does not occur) is exempt from all provisions
of the Act except Section 9(a)(2).
    
   
       With one exception, the prior analysis of NSP's entitlement to an
exemption under Section 3(a)(2) following the Spin-off is equally applicable to
NSP in the event that the Spin-off does not occur.  NSP will continue to be
predominantly a public-utility company, with NSP-W (its only subsidiary that is
a public-utility company) representing less than 15% of its utility operating
revenues for the year ended December 31, 1998.  Other than the BMG operations,
all of NSP's operations as a public utility will be confined to its state of
incorporation and states contiguous thereto.  Thus, the issue presented is
whether, under Section 3(a)(2), all of NSP's operations as a public utility must
be confined to NSP's state of incorporation and states contiguous thereto or
whether a de minimis amount (38) may be conducted in a non-contiguous state.  In
light of the legislative history of Section 3(a)(2), the significant changes in
the utility industry since the enactment of Section 3(a)(2), the views expressed
in the 1995 Report, the approval of the corporate structure in question by the
applicable state regulatory authorities and the de minimis nature of the BMG
operations, Applicant believes that it should be exempt under Section 3(a)(2).
    
   
       The legislative history of Section 3(a)(2) does not provide a
dispositive answer to the question of whether a holding company can conduct a de
minimis amount of utility operations in a non-contiguous state.  An indication
of the proper interpretation of Section 3(a)(2) is given by
    

- -------------------------
(36)   See, UNION ELECTRIC CO. OF MISSOURI, 5 S.E.C. 252 (1939) (where the
       Commission concluded that "it is plain that under that subsection
       [3(a)(2)], Congress intended us to ignore as irrelevant the place of
       operation of the operating subsidiaries of the holding company, and that
       we should in the instant case consider solely whether the place of
       operations of Union Electric Company of Missouri, itself, as an
       operating company, are confined to the state of Missouri and contiguous
       states."); and IN RE NORTHERN STATES POWER CO., Holding Co. Act Release
       No. 22334, 24 SEC Docket 405 (December 23, 1981) (approving the
       acquisition by a holding company of a subsidiary and allowing the
       holding company to maintain exempt status pursuant to section 3(a)(2),
       notwithstanding that the new subsidiary had operations in states
       non-contiguous to the holding company's state of organization).

(37)   1995 Report at 72-74.

(38)   The de minimis nature of BMG's utility operations to the existing
       utility operations of NSP is shown on the prior pages of this
       Application, with BMG's net utility assets, utility revenues and net
       income representing significantly less than 1% of the net utility
       assets, utility revenues and net income of NSP on a stand-alone basis
       without the inclusion of NSP-W.

the Senate Report to Senate Bill 2796 (39) in which it is stated that Section
3(a)(2) of the Act is to govern a case where:
    
   
       the company is itself a utility, being a holding company only in form by
       reason of the fact that it has one or more minor subsidiary
       utilities.(40)
    
   
This statement clearly implies that the focus of Section 3(a)(2) is on the size
of the utility subsidiaries and not on requiring that every aspect of the
utility operations of the parent holding company must be located solely in its
state of incorporation and states contiguous thereto.  Applicant does not know
of any statements in the legislative history of Section 3(a)(2) that would
preclude an exempt holding company under Section 3(a)(2) from having a de
minimis amount of utility operations in a non-contiguous state.
    
   
       Applicant is aware that, in EASTERN SHORE PUBLIC SERVICE COMPANY,
5.S.E.C.1022 (1940), the Commission addressed the meaning of the phrase "whose
operations as such do not extend beyond the State in which it is organized and
States contiguous thereto" in Section 3(a)(2).  While the Commission's
interpretation of this phrase was not determinative to the case as Eastern Shore
did not meet the requirement of being predominantly a public utility company
(the revenues of Eastern Shore's utility subsidiaries represented in excess of
75% of the combined utility revenues of the system), the Commission interpreted
the phrase as requiring that the holding company's public utility operations be
confined to its state of incorporation and states contiguous (i.e., touching)
thereto.  This case, however, is distinguishable as the Commission was not faced
with the situation, like the present case, where the non-contiguous operations
reflected less than 1% of the holding company's utility revenues.
    
   
       Moreover, in order to respond flexibly to the legislative, regulatory
and technological changes that are transforming the structure and shape of the
utility industry,(41) the Commission has indicated a willingness to reconsider
precedent in interpreting Section 3(a) of the Act.(42)  In this regard, the
Commission has announced its intention to reject bright-line tests and rather to
consider the specific facts and circumstances surrounding each specific request
for exemption, giving significant attention to the availability of state
regulation for the proposed transaction.(43)  In the present case, the proposed
structure with the BMG operations being conducted directly by NSP has been
approved by the Minnesota Commission, the Arizona Commission and the North
Dakota Commission.  None of these commissions expressed any reservation about
their ability to effectively regulate the utility operations of NSP.  In fact,
the Minnesota Commission, the North Dakota Commission and the South Dakota
Commission have effectively regulated NSP as an

exempt holding company under Section 3(a)(2) for many years.  The addition of
the BMG operations to NSP will not affect this regulation.  Thus, the present
case is not one involving an unregulated entity through which potential abuse
could occur.  Instead, NSP will be subject to extensive regulation by four state
regulatory commissions.  Under these circumstances, it seems evident that the
holding company structure will not be used to evade state or local regulation or
that regulation under the Act is needed to supplement state regulation in order
to prevent detriment to the interests protected by the Act.
    
   
       As acknowledged by the Staff in the 1995 Report, "the [Commission's]
decisions under [Section 3(a)(1) and 3(a)(2)] have generally focused on size as
a proxy for effective state regulation.  The result has been a somewhat
confusing array of decisions."(44)  The present case amply demonstrates this
confusing array.  As shown previously, NSP meets the criteria for an exemption
under Section 3(a)(2) if BMG is a wholly-owned subsidiary of NSP.  The same
result follows if BMG is made part of the operations of NSP-W, as the location
of utility operations of subsidiaries is not relevant under Section 3(a)(2).
UNION ELECTRIC CO. OF MISSOURI, 5 S.E.C.252 (1939).  Finally, if BMG were
combined with Viking Gas Transmission Company (NSP's wholly-owned interstate
pipeline), Viking would appear to qualify for an exemption under Rule 7 under
the Act.  BMG's revenues from its gas utility operations have averaged less than
$5 million annually for the last three calendar years ($4.6 million for 1998,
$5.3 million for 1997, and $4.4 million for 1996).  Viking, with annual revenues
in excess of $19 million from its interstate pipeline business, would appear to
be engaged primarily in a business other than the gas utility business for
purposes of Rule 7.  It is only when BMG's operations are part of NSP that an
issue arises under Section 3(a)(2).  Yet, there does not appear to be any policy
or purpose of the Act that is served by permitting the above corporate
structures to be exempt under Section 3(a)(2), but not permitting a corporate
structure where BMG is part of the parent company operations of NSP.
    
   
       As stated previously, the precise issue presented is whether, under
Section 3(a)(2), a holding company can have a de minimis amount of utility
operations outside of its state of incorporation and states contiguous thereto.
In EASTERN GAS, SUPRA, the Commission arguably answered this question in the
negative.  However, through numerous no-action letters and orders, the
Commission has effectively permitted non-contiguous operations that historically
would have appeared to be utility operations.  This is shown by the various
no-action letters and orders issued in the context of energy marketing.
    
   
       The initial series of no-action letters permitted utility affiliates or
independent companies to engage in the wholesale sale of electricity.  ENRON

activities did not constitute "utility" operations under the Act and the
decisions were in response, at least in part, to the rapidly changing
electricity and gas utility industry.  The next series of no-action letters and
orders permitted the retail sale of electricity and natural gas where the

company did not own any physical utility assets.  LG&E POWER MARKETING, INC.,
SEC No-Action Letter, April 26, 1996; UNITIL CORPORATION, Holding Company Act
Release No. 26527 (May 31, 1996).  Again, the basis for these decisions was that
this activity did not constitute "utility" operations.  The final step was the
sale by marketing companies of electricity and natural gas coupled with the
installation and/or ownership of certain ancillary equipment such as meters,
electric wire droplines, breaker panels and short segments of gas pipe or
electric wiring to connect the customer to the local distribution system.  ENRON
CAPITAL & TRADE RESOURCES CORP., SEC No-Action Letter, February 13, 1997; SUNOCO
POWER MARKETING, L.L.C., SEC No-Action letter, July 24, 1997; SEI HOLDINGS,
INC., Holding Company Act Release No. 26581 (September 26, 1996).
    
   
       The overall effect of the foregoing decisions is that exempt holding
companies today are permitted under the Act to sell electricity and natural gas
at wholesale throughout the United States and at retail in numerous states
which, through retail pilot programs or legislative enactment, have permitted
such action to occur.  Often, the regulation of such energy marketing activities
is far less than the typical, extensive regulation imposed by states on
traditional electric and gas utilities, including the regulation imposed on the
BMG operations in Arizona by the Arizona Commission.
    
   
       Applicant's point in discussing the above energy marketing decisions is
to show that historical perceptions of permitted utility operations under
Section 3(a)(2) have changed significantly.  Applicant does not question the
wisdom or correctness of the various energy marketing no-action letters and
orders.  In fact, Applicant supports such decisions.  Yet, there is nothing in
the Act or its legislative history expressly stating that an entity which
provides electric or natural gas service is not an electric utility company or a
gas utility company merely because it does not own or operate certain physical
assets.  Similarly, there is nothing in the Act or, to the knowledge of the
Applicant, its legislative history requiring that exempt holding companies under
Section 3(a)(2) cannot have a de minimis amount of utility operations in a
noncontiguous state.  It is for this reason, along with the approval of the
applicable state utility commissions that will regulate NSP, the ability of NSP
to otherwise qualify for an exemption and the lack of potential harms to the
interests sought to be protected by the Act, that the Applicant believes it
should be exempt under Section 3(a)(2) from all provisions of the Act other than
Section 9(a)(2).  The granting of such exemption would be consistent with the
Commission's broad power to interpret the terms, phrases and provisions of the
Act.  See, e.g., GAZ METROPOLITAIN, INC., Holding Company Act Release No. 26170
(November 23, 1994).  In addition, the uniqueness of the facts in the present
case make it highly unlikely that the grant of an exemption under
Section 3(a)(2) will be relied upon for precedential effect in future cases.
    
Item 4.  Regulatory Approvals

               Set forth below is a summary of the regulatory approvals that NSP
and BMG expect to obtain in connection with the Merger.  It is a condition to
the consummation of the Merger that final orders approving the Merger be
obtained from the Commission under the Act and from the various federal and
state commissions described below on terms and conditions which would not have,
or would not be reasonably likely to have, a material adverse effect on the
business, assets, financial condition or results of operations of BMG or NSP and
its prospective


                                          37
<PAGE>

subsidiaries taken as a whole or which would be materially inconsistent with the
agreements of the parties contained in the Merger Agreement.

A.  Antitrust

       The HSR Act and the rules and regulations thereunder provide that
certain transactions (including the Transaction) may not be consummated until
certain information has been submitted to the Department of Justice ("DOJ") and
Federal Trade Commission ("FTC") and the specified HSR Act waiting period
requirements have been satisfied.  DOJ terminated the HSR Act waiting period on
April 3, 1998.
   
       The expiration of the HSR Act waiting period does not preclude the
Antitrust Division or the FTC from challenging the Transaction on antitrust
grounds; however the Applicant believes that the Transaction will not violate
Federal antitrust laws.
    
B.  State Public Utility Regulation
   
       Applications for approval of the Merger and related transactions were
filed on January 12, 1998 with the Arizona Commission, on January 20, 1998 with
the Minnesota Commission, and on March 5, 1998 with the North Dakota Commission.
Each Commission found, in general, that the Merger was in the public interest.
The Minnesota Commission approved the Merger on May 7, 1998, the North Dakota
Commission approved the Merger on June 3, 1998 and the Arizona Commission
approved the Merger on July 21, 1998.
    
   
       Consummation of the Spin-off will require the prior approval of the
Arizona Commission.  NSP also will seek the approval of the Spin-off by the
Minnesota Commission and the North Dakota Commission.  NSP submitted
applications for such approval on January 13, 1999 with the Minnesota
Commission, January 19, 1999 with the North Dakota Commission, and January 23,
1999 with the Arizona Commission.  Following consummation of the Transaction,
NSP and BMG expect to engage in various intercompany transactions.  These
affiliated interest transactions require prior approval of the Arizona
Commission and the Minnesota Commission.  Accordingly, as part of the
application for approval of the Spin-off, NSP will seek authorization for these
affiliated interest transactions from the Arizona and Minnesota Commissions.
    
   
       NSP is in the process of preparing the foregoing applications to the
Arizona, Minnesota and North Dakota Commissions.  NSP currently anticipates
receiving such approvals approximately four months following the filing of the
applications.
    
       Except as set forth above, no other state or local regulatory body or
agency and no other Federal commission or agency has jurisdiction over the
transactions proposed herein.

Item 5.  Procedure
   
               The Commission is respectfully requested to issue and publish not
later than September 15, 1998, the requisite notice under Rule 23 with respect
to the filing of this
    

                                          38

Application-Declaration, such notice to specify a date not later than October 6,
1998, by which comments must be entered and a date not later than October 7,
1998, as the date after which an order of the Commission granting and permitting
this Application-Declaration to become effective may be entered by the
Commission.
    
               It is submitted that a recommended decision by a hearing or other
responsible officer of the Commission is not needed for approval of the proposed
Transaction.  The Division of Investment Management may assist in the
preparation of the Commission's decision.  There should be no waiting period
between the issuance of the Commission's order and the date on which it is to
become effective.

Item 7.  Information as to Environmental Effects

               The Transaction neither involves "major federal actions" nor
"significantly [affects] the quality of the human environment" as those terms
are used in Section (2)(C) of the National Environmental Policy Act, 42 U.S.C.
S.E.C. 4332.  The only federal actions related to the Transaction pertain to the
Commission's declaration of the effectiveness of the Registration Statement, the
approvals and actions described under Item 4 and Commission approval of this
Application-Declaration.  Consummation of the Transaction will not result in
changes in the operations of NSP, NSP-W or BMG that would have any impact on the
environment.  No federal agency is preparing an environmental impact statement
with respect to this matter.

IN THE MATTER OF A REQUEST BY 
NORTHERN STATES POWER COMPANY                           PETITION FOR APPROVAL
FOR APPROVAL OF A TRANSFER OF                                                
GAS UTILITY ASSETS TO A NEWLY                                                
INCORPORATED SUBSIDIARY AND                                                  
AFFILIATED INTEREST AGREEMENTS


                                                                             
I.   INTRODUCTION AND SUMMARY

     Pursuant to Minn. Stat. Sections 216B.48 and .50 and related Minnesota 
Rules, Northern States Power Company ("NSP" or the "Company") requests 
approval from the Minnesota Public Utilities Commission ("MPUC" or 
"Commission") of (1) the transfer of gas utility assets and related 
liabilities previously owned by Black Mountain Gas Company of Arizona to a 
newly-formed subsidiary of NSP, which will be named Black Mountain Gas 
Company ("New BMG"); and (2) an unexecuted Administrative Services Agreement 
and an unexecuted Tax Sharing Agreement (the "Agreements") with New BMG.  NSP 
proposes the new Agreements be effective on the date New BMG becomes an 
operating subsidiary of NSP, proposed to be May 1, 1999. NSP believes 
approval of the transfer is necessary because NSP has Minnesota electric and 

                                       1
<PAGE>

natural gas public utility operations.(1) Approval of the Agreements is
necessary because New BMG will be a subsidiary of NSP.

     On December 29, 1997, NSP and Black Mountain Gas Company, an Arizona
corporation ("Old BMG") entered into a Merger Agreement.  The structure of the
transaction was for Old BMG to be merged directly into NSP with NSP as the
survivor and Old BMG ceasing to exist.  At the time of executing the Merger
Agreement, NSP believed that such structure was appropriate and required to
effectuate the acquisition of Old BMG under the Federal Public Utility Holding
Company Act (PUHCA).  All regulatory filings associated with the merger and the
proxy materials presented to the BMG shareholder for approval of the merger were
premised on this structure.  This Commission approved the merger of Old BMG into
NSP by Order, dated May 7, 1998, in Docket No. G002/PA-98-108.  The merger was
completed in July 1998.

     In hindsight, NSP realizes that the corporate structure chosen was not
necessarily the best structure.  For the reasons explained below, NSP believes
the Old BMG operations should be conducted through a wholly-owned subsidiary and
not as part of the direct operations of NSP.  For this reason, NSP is requesting
that the Commission issue an Order approving NSP's transfer of the gas utility
assets associated with the former operations of Old BMG to a newly-formed
subsidiary, New BMG.  This transfer will benefit NSP, its customers in Minnesota
and the customers of New BMG in Arizona.  Further, NSP is requesting the
Commission approve affiliated interest agreements between NSP and New BMG.

- --------------
    (1)NSP understands the issue of Commission jurisdiction over the 
transfer of assets outside Minnesota is presently being contested in Docket 
No. E017/PA-99-1345.  For purposes of this Petition, NSP assumes Commission 
jurisdiction.

                                       2

     NSP's Minnesota utility operations will not be adversely affected by these
transactions.  NSP respectfully requests expedited review of this Petition and
seeks approval by mid-April, 1999.

III. THE LEGAL STANDARDS FOR REVIEW     

     Minn. Stat. Sections 216B.48 and .50 (1996) govern the Commission's review
of this Petition.  Minn. Stat. Section 216B.48 (1996) provides, in relevant
part:

                                       4
<PAGE>

     The Commission shall approve the contract or arrangement made or entered
     into after that date only if it clearly appears and is established upon 
     investigation that it is REASONABLE AND CONSISTENT WITH THE PUBLIC 
     INTEREST.  (Emphasis added).

     Minn. Stat. Section 216B.50 provides in relevant part:

     Upon the filing of an application for the approval and consent of the
     commission thereto the commission shall investigate, with or without
     public hearing, and in case of a public hearing, upon such notice as
     the commission may require, and if it shall find that the proposed
     action is CONSISTENT WITH THE PUBLIC INTEREST it shall give its
     consent and approval by order in writing.(Emphasis added).

     In this Petition, NSP will demonstrate that the transactions fully 
comply with the requirements of Minn. Stat. Sections 216B.48 and .50 (1996) 
and are consistent with the public interest.  The Parties are undertaking 
these transactions to create a corporate structure that will be better for 
NSP, its Minnesota customers and the customers of New BMG in Arizona.  The 
Parties have structured the transactions so that NSP's Minnesota utility 
operations will not be adversely effected.  This meets the legal standard 
established in MATTER OF PROPOSED MERGER OF MINNEGASCO, INC. WITH AND INTO 
ARKLA, INC., Docket No. G-008/PA-090-604 (1990) and MATTER OF PROPOSED MERGER 
OF MINNEGASCO, INC. WITH AND INTO HOUSTON INDUSTRIES, INC. AND HOUSTON 
LIGHTING AND PAPER CO., Docket No. G-008/PA-96-950 (1997).  In addition, 
NSP's Arizona gas utility operations and customers will benefit.

IV.  THE  PARTIES

     NSP is an investor-owned gas and electric utility incorporated in the state
of Minnesota.  Its historic service area includes parts of Minnesota, Wisconsin,
Michigan, North Dakota and South Dakota.  NSP (Minnesota) currently provides
natural gas utility service to approximately

                                       5
<PAGE>

400,000 customers in Minnesota, North Dakota and South Dakota.(2)  NSP also 
provides electric utility service to about 1.3 million customers in these 
same States. NSP (Wisconsin), a wholly-owned subsidiary of NSP, provides gas 
and electric service in Wisconsin and Michigan.

     New BMG will be a newly-formed subsidiary of NSP, and a corporation
incorporated in the state of Minnesota.  It will be the recipient of the
transfer of NSP's gas utility assets and associated liabilities in Maricopa
County, Arizona, and will be engaged in business as a local gas distribution
company there.  New BMG's assets, liabilities and operations are intended to be
virtually identical to the assets, liabilities and operations of Old BMG had it
continued in existence as a subsidiary of NSP and had not been merged into NSP. 
New BMG's Cave Creek division will serve about 5,000 natural gas customers in
areas in and around Phoenix and Scottsdale.  Its Page Division will serve about
1,300 customers in the City of Page through underground distribution of propane
vapor.  New BMG will also provide propane service to an area in Coconino County,
Arizona, through a subsidiary, Lake Powell Propane.

V.   PETITION FOR APPROVAL OF ASSET TRANSFER

     By an Agreement dated December 29, 1997, NSP and Old BMG agreed to merge
into a single company, with NSP as the survivor.  The Agreement contemplated a
"pooling of interests" merger.  As explained previously, NSP now has realized
that it would be more appropriate to have the Old BMG operations conducted
through a subsidiary on a long term 

- --------------
    (2)NSP recently established a retail operation in South Dakota, and is 
presently serving less than 10 retail transportation-only customers pursuant 
to tariff on file with the South Dakota PUC.  SEE Docket NG97-21, final 
action pending.

                                       6
<PAGE>

basis.  The purpose of this application is to seek the requisite authority to 
cause the NSP operations of Old BMG to be transferred to such subsidiary.

     There are several concerns with the current structure under which the Old
BMG operations are conducted directly by NSP. First, NSP becomes fully subject
to regulation as a public utility by the Arizona Corporation Commission (the
"Arizona Commission"), which will result in unnecessary expense to NSP.  It also
will impose an unnecessary level of complexity to the Arizona Commission in
regulating the Old BMG operations and will require NSP to present various issues
to the Arizona Commission that are irrelevant to Arizona gas ratepayers.  For
example, NSP would appear to need Arizona Commission approval to issue
securities even if the proceeds of the securities are to finance NSP's electric
operations in Minnesota.  SEE ACC Rule R14-2-805 (1992).

     In addition, the Old BMG operations make up only 1.4% of total NSP natural
gas customers, .03% of total NSP gas investment, and 1.4% of total NSP retail
gas revenues.  In rate cases for Old BMG's operations in Arizona, NSP would need
to segregate the Old BMG assets and financial results from its total NSP Company
financial statements.  In such rate cases, NSP would also need to create a
stand-alone, imputed capital structure for Old BMG in order to determine, among
other things, an appropriate return on equity.

     The creation of a subsidiary also will enhance accurate allocation of costs
to New BMG.  At the present time, NSP is segregating all operating and employee
costs of Old BMG's operations from NSP's  other gas utility operations and
allocating certain NSP corporate costs to the Arizona jurisdiction.  Yet,
accounting and allocating these various segregated and common expenses is a
difficult task, which complicates accounting for the costs of the Minnesota

                                       7
<PAGE>

jurisdiction gas operations.  By creating a subsidiary, all direct day-to-day
operating expenses of New BMG obviously would be reported in the stand-alone
financial statements of New BMG.  Any services provided by NSP to New BMG would
be charged-back pursuant to the Administrative Services Agreement between NSP
and New BMG that would be approved by this Commission and the Arizona
Commission.

     As part of this restructuring and completion of its acquisitions of the Old
BMG operations, NSP is also seeking the approval of the Securities and Exchange
Commission ("SEC") under the Public Utility Holding Company Act of 1935, as
amended.  SEC approval is contingent upon approval of the restructuring of BMG's
operations into New BMG by this Commission.

     Appendix 1 provides the proposed accounting entries for the transfer of the
Old BMG assets and liabilities of NSP to New BMG.  The pooling of interests,
approved in Docket No. G002/PA-98-108, will not be affected.  The transaction
will occur at "book value," and NSP will experience no gain or loss associated
with the transfer.  The pre-existing Old BMG debt will be assigned to New BMG. 

VI.  PETITION FOR APPROVAL OF AFFILIATED INTEREST AGREEMENTS

     Following completion of the transfer of Old BMG's operations to New BMG,
NSP and New BMG will be affiliated interests under Minn.  Stat. Section 216B.48.
The parties thus would enter into certain affiliated interest agreements
("Agreements") to define the terms of their relationship.  In particular, NSP
requests approval of an Administrative Services Agreement and a Tax Sharing
Agreement with New BMG.

                                       8
<PAGE>

     Appendix 2 contains certain documentation required by Rule 7825.2200,
including a copy of the Agreements in Attachment 2-A.  In addition, NSP is
providing in Appendix 2 the information required pursuant to the filing
guidelines recently approved in Docket G,E-999/CI-98-651.

     As a result of the NSP/Old BMG merger, NSP provides various corporate and
other services to its retail gas operations in Arizona and makes an internal (to
NSP) allocation of costs to the Arizona gas operation, just as NSP provides an
internal allocation to its retail gas operations in North Dakota.  The cost of
service settlement approved by the Commission in the NSP Gas rate case (Docket
No. G002/GR-97-1606) provides for an adjustment to the 1998 test year cost of
service to reflect this allocation to NSP's Arizona gas operations.

     As a result of the proposed transfer to New BMG, the internal NSP cost 
allocation will be replaced by a charge-back via the Administrative Services 
Agreement ("ASA").  The proposed Administrative Service Agreement provides a 
contractual mechanism whereby NSP and New BMG can provide various services to 
each other in order to take advantage of efficiencies and economies of scale 
and charge each other on a fully-allocated cost basis.(3) The Tax Sharing 
Agreement ("TSA") will allow NSP and New BMG to reflect the impacts of NSP's 
consolidated corporate tax return, and is similar to numerous TSAs between 
NSP and subsidiaries previously approved by the Commission.

- --------------
    (3)NSP Gas will not provide SCADA or gas dispatch services to New BMG, as 
it does for NSP(W) and Viking Gas.  If such services were provided in the 
future, NSP Gas would file an appropriate agreement for Commission approval.

                                       9
<PAGE>

     The Agreements are proposed to be effective on the date New BMG is
established as an operating subsidiary of NSP, proposed to be May 1, 1999.  The
Agreements may be terminated by either party on 60 days notice thereafter.

     In order to minimize the risk that the Commission and Arizona Corporation
Commission ("Arizona Commission") reach conflicting decisions, the ASA and TSA
are being filed for review and approval by the Arizona Commission
contemporaneous with the instant filing.  If requested, NSP will share pertinent
materials from the Arizona Commission proceeding with the Commission and parties
to this proceeding.

VII. THE TRANSACTIONS ARE IN THE PUBLIC INTEREST

     The transactions will not change the operations of NSP or the provision of
electric or natural gas service to Minnesota customers.  The transfers will have
no material immediate or direct impact on the rates and other tariffs of NSP on
file with and approved by the Commission, and will provide for better financial
management of the Arizona gas operations, and thus less complex financial
management (and thus jurisdictional accounting) for the Minnesota jurisdiction
gas operations.  The transfer would thus serve the public interest and should be
approved.  

     Moreover, the proposed Administrative Services Agreement and Tax Sharing
Agreements are in the public interest and satisfy the requirement of Minn. Stat.
Section 216B.48.  Thus the proposed transfer and Agreements should be approved.

                                  SUMMARY OF FILING

     Take notice that on January 13, 1999, Northern States Power Company 
("NSP") tendered for filing a petition for Commission approval of (1) the 
transfer of NSP's gas utility assets and related liabilities in the State of 
Arizona that were previously owned by Black Mountain Gas Company of Arizona 
to a newly-formed subsidiary of NSP, which will be named Black Mountain Gas 
Company ("New BMG") and (2) an Administrative Services Agreement and a Tax 
Sharing Agreement ("Agreements") between NSP and New BMG.  NSP requests 
Commission approval of the Agreements by mid-April 1999, with the transfer of 
gas utility assets and liabilities to New BMG on May 1, 1999.

<PAGE>

NORTHERN STATES POWER COMPANY
STATE OF MINNESOTA

Pursuant to Commission Rules 7825.2200, and the filing guidelines adopted in 
Docket No. G,E-999/CI-98-651, NSP provides the following information:

1.   A.   DESCRIPTIVE TITLE OF EACH CONTRACT OR AGREEMENT:

     Administrative Services Agreement between Northern States Power Company and
Black Mountain Gas Company.

     Tax Sharing Agreement between Northern States Power Company and Black
Mountain Gas Company.

     B.   GENERAL DESCRIPTION OF AGREEMENTS:

     In the original order in Docket No. G002/PA-98-108 dated May 7, 1998, the
Commission approved the merger of NSP and Black Mountain Gas of Arizona ("Old
BMG").  The merger was effectuated on July 16 1998.  As a result of the merger,
NSP provides various corporate and other services to its retail gas operations
in Arizona.  NSP is now seeking to transfer the Arizona retail gas operations by
transfer to New BMG.  As a result, the internal cost allocation will be replaced
by an assignment and charge-back via an Administrative Services Agreement
("ASA"), and the impacts of NSP's consolidated corporate tax returns will be
reflected through the TSA.

2.   A COPY OF THE CONTRACT OR AGREEMENT:

     Attachment 2-A contains a copy of the unexecuted ASA and TSA.  The
     Agreements would be executed contemporaneous with the asset transfer to New
     BMG.

3.   A LIST AND PAST HISTORY OF ALL CONTRACTS OR AGREEMENTS OUTSTANDING BETWEEN
     THE PETITIONER AND AFFILIATED INTEREST, THE CONSIDERATION RECEIVED BY THE
     AFFILIATED INTEREST FOR SUCH CONTRACTS OR AGREEMENTS, AND A VERIFIED
     SUMMARY OF THE RELEVANT COST RECORDS PERTAINING TO THE SAME.

     Not applicable.  New BMG would be a new subsidiary of NSP.

4.   A DESCRIPTIVE SUMMARY OF THE PERTINENT FACTS AND REASONS WHY SUCH
     CONTRACT OR AGREEMENT IS IN THE PUBLIC INTEREST

     NSP only recently merged with Old BMG, so there has been little
     consolidation of gas operations.  In addition, because of the significant
     distance between NSP's retail gas operations in Minnesota and the New BMG
     operations in Arizona,  New BMG will 

<PAGE>

     operate on a less integrated basis than, for example, the NSP retail gas
     operations in North Dakota.  As a result, the proposed ASA provides for
     services and a cost allocation similar to the ASA between NSP and Viking
     Gas Transmission Company ("Viking") approved in Docket No. G002/AI-93-1235,
     because both BMG and Viking will operate relatively autonomously from NSP
     Gas, with separate operations, management and financial statements.  

     In addition, for those services provided by NSP, the assignment of costs to
     New BMG under the ASA will comply with the Commission's fully allocated
     costing principles adopted in the 1994 policy statement in Docket 
     No. G,E-999/CI-90-1008 and the methods used by NSP to account for 
     administrative services exchanged between NSP and its regulated and 
     unregulated subsidiaries as approved in a series of Commission dockets over
     the past several years.   SEE, e.g., Docket No. E002/AI-97-1677 (Order
     dated January 15, 1998) (Ultra Power Technologies, Inc.); Docket 
     No. E002/AI-97-300 (Order dated April 15, 1997) (Seren Innovations, Inc.);
     Docket No. E002/AI-94-1041 (Order dated February 9, 1995) (First Midwest
     Auto Park, Inc.). The cost impact to NSP caused by the change from an 
     internal accounting allocation to a charge-back mechanism through the 
     ASA is not expected to be material.(4)

5.   COMPETITIVE BIDDING:  IF INVITATIONS FOR SEALED WRITTEN PROPOSALS HAVE NOT
     BEEN MADE, AN EXPLANATION OF THE DECISIONS TO THE EFFECT WILL BE SUBMITTED

     Not applicable.  In this case, NSP will be the vendor of services to New
     BMG.  To the extent appropriate, New BMG will be able to use bidding
     processes or contract with third party vendors for certain services (e.g.,
     distribution engineering and construction or gas supply management) if such
     third party services would provide lower costs than 

- --------------
    (4)Under the NSP cost allocation methods filed pursuant to the 1008 
docket, NSP charges an overhead charge in addition to the actual costs 
incurred and billed to subsidiaries like BMG.  Because of the relatively 
separate operations, NSP's accounting to date treated the Arizona gas 
operations more like a subsidiary than an NSP gas jurisdiction. (i.e., NSP 
charged back incurred costs plus overheads.)  When New BMG becomes a 
subsidiary, NSP will also charge a working capital fee to New BMG's monthly 
inter-company bill.  NSP imposes a similar fee on inter-company bills to 
Viking Gas, approved in Docket G002/AI-93-1235.

<PAGE>

     procuring such services from NSP.  The Arizona Commission would have
     jurisdiction to review the reasonableness of NSP cost charge-backs to
     New BMG in New BMG rate cases.

6.   ACCESS TO CUSTOMER INFORMATION

     New BMG will initially continue to use a customer billing system separate
     from the NSP CSS system.  Also, NSP and New BMG are both regulated
     utilities who provide retail service subject to the rules and regulations
     of the MPUC and ACC, respectively.

_________________
IN THE MATTER OF A REQUEST BY 
NORTHERN STATES POWER COMPANY                             PETITION FOR APPROVAL
FOR APPROVAL OF A TRANSFER OF
ARIZONA GAS UTILITY ASSETS TO A 
NEWLY INCORPORATED SUBSIDIARY



I.   INTRODUCTION AND SUMMARY

     Pursuant to N.D. Cent. Code Section 49-04-05 and related Rules, Northern 
States Power Company ("NSP" or the "Company") requests approval from the 
North Dakota Public Service Commission ("NDPSC" or "Commission") of the 
transfer of gas utility assets and related liabilities that previously were 
owned by Black Mountain Gas Company of Arizona to a newly-formed subsidiary 
of NSP, which will be named Black Mountain Gas Company ("New BMG").  NSP 
proposes that New BMG become an operating subsidiary of NSP on May 1, 1999.  
NSP believes approval of the transfer is necessary because NSP has North 
Dakota public utility operations.

     On December 29, 1997, NSP and Black Mountain Gas Company, an Arizona 
corporation ("Old BMG") entered into a Merger Agreement.  The structure of 
the transaction was for Old BMG to be merged directly into NSP with NSP as 
the survivor and Old BMG ceasing to exist.  At the time of executing the 
Merger Agreement, NSP believed that such a structure was appropriate and 
required to effectuate the acquisition of Old BMG under the Federal Public 
Utility Holding Company Act (PUHCA).  All regulatory filings associated with 
the merger


                                     1

<PAGE>

and the proxy materials presented to the BMG shareholder for approval of the 
merger were premised on this structure.  This Commission  approved the merger 
of Old BMG into NSP by Order, dated June 3, 1998, in Docket No. 
PU-400-98-118.  The merger was completed in July 1998.

     In hindsight, NSP realizes that the corporate structure chosen was not 
necessarily the best structure.  For the reasons explained below, NSP 
believes the Old BMG operations should be conducted through a wholly-owned 
subsidiary and not as part of the direct operations of NSP.  For this reason, 
NSP is requesting that the Commission issue an Order approving NSP's transfer 
of the gas utility assets associated with the former operations of Old BMG to 
a newly-formed subsidiary, New BMG.  This transfer will benefit NSP, its 
customers in North Dakota and the customers of New BMG in Arizona.

     NSP's North Dakota utility operations ("NSP-ND") will not be adversely 
affected by this transfer.  NSP-ND respectfully requests prompt review of 
this Petition and seeks approval by mid-April, 1999.

II.  THE LEGAL STANDARDS FOR REVIEW

     N.D. Cent. Code Section 49-04-05 governs the Commission's review of this 
Petition.  It provides, in relevant part that a "public utility may not 
dispose of, encumber, merge, or consolidate its franchise, works, or system 
necessary or useful in the performance of its duties to the public, without 
prior Commission approval."

     The North Dakota Supreme Court has held that approval of a transaction 
governed by this statute is mandatory.  FARGO FREIGHT TRUCKING CO. V. NORTH 
DAKOTA PUBLIC SERVICE COMMISSION, 129 N.W.2d 368 (1964).


                                     2

<PAGE>

     In prior cases, the commission established that the standard for 
approval does not require an affirmative finding of public benefit, just a 
finding that the transaction is compatible with the public interest.  IN RE 
MINOT TELEPHONE CO., Docket No. PU-156-94-11, 1994 WL 135200 at *2 (March 23, 
1994).  In the MINOT Docket, the Commission found a transfer to be in the 
public interest in the absence of evidence that "the transfer will be 
injurious to the rights of the public or adversely affect other utilities." 
ID.

     The statute is not clear whether Commission approval is required to 
dispose of utility assets or operations outside North Dakota.  If so, in this 
Petition NSP will demonstrate that the transfer fully complies with the 
requirements of N.D. Cent. Code Section 49-04-05 and the test applied in the 
Minot Docket.  The Parties are undertaking this transfer to create a 
corporate structure that will be better for NSP and its natural gas 
customers.  The Parties have structured the transactions so that NSP-ND's 
utility operations or customers will not be adversely effected.

III. THE  PARTIES

     NSP is an investor-owned gas and electric utility incorporated in the 
state of Minnesota.  Its historic service area includes parts of Minnesota, 
Wisconsin, Michigan, North Dakota and South Dakota.  NSP (Minnesota) 
currently provides natural gas utility service to approximately 400,000 
customers in Minnesota, North Dakota and South Dakota.(1) NSP also provides 
electric utility service to about 1.3 million customers in these same States. 
NSP (Wisconsin), a wholly-owned subsidiary of NSP, provides gas and electric 
service in Wisconsin and Michigan.


- ----------------------
  (1) NSP recently established a retail operation in South Dakota, and is 
presently serving less than 10 retail transportation-only customers pursuant 
to tariff on file with the South Dakota PUC.  SEE Docket NG97-21, final 
action pending.


                                     3

<PAGE>

     New BMG will be a newly-formed subsidiary of NSP, and a corporation 
incorporated in the state of Minnesota.  It will be the recipient of the 
transfer of NSP's gas utility assets and associated liabilities in Maricopa 
County, Arizona, and will be engaged in business as a local gas distribution 
company there.  New BMG's assets, liabilities and operations are intended to 
be virtually identical to the assets, liabilities and operations of Old BMG 
had it continued in existence as a subsidiary of NSP and had not been merged 
into NSP. New BMG's Cave Creek division will serve about 5,000 natural gas 
customers in areas in and around Phoenix and Scottsdale.  Its Page Division 
will serve about 1,300 customers in the City of Page through underground 
distribution of propane vapor.  New BMG will also provide propane service to 
an area in Coconino County, Arizona, through a subsidiary, Lake Powell 
Propane.

IV.  REASONS  FOR THE APPROVAL OF ASSET TRANSFER

     By an Agreement dated December 29, 1997, NSP and Old BMG agreed to merge 
into a single company, with NSP as the survivor.  The Agreement contemplated 
a "pooling of interests" merger.  As explained previously, NSP now has 
realized that it would be more appropriate to have the Old BMG operations 
conducted through a subsidiary on a long term basis.  The purpose of this 
application is to seek the requisite authority, if necessary under Section 
49-04-05, to cause the NSP operations of Old BMG to be transferred to such 
subsidiary.

     There are several concerns with the current structure under which the 
Old BMG operations are conducted directly by NSP. First, NSP becomes fully 
subject to regulation as a public utility by the Arizona Corporation 
Commission (the "Arizona Commission"), which will result in unnecessary 
expense to NSP.  It also will impose an unnecessary level of complexity to 
the Arizona Commission in regulating the Old BMG operations and will require 
NSP to present


                                     4

<PAGE>

various issues to the Arizona Commission that are irrelevant to Arizona gas 
ratepayers.  For example, NSP would appear to need Arizona Commission 
approval to issue securities even if the proceeds of the securities are to 
finance improvements to NSP's electric operations in North Dakota or 
Minnesota.  SEE ACC Rule R14-2-805 (1992).

     In addition, the Old BMG operations make up only 1.4% of total NSP 
natural gas customers, .03% of total NSP gas investment, and 1.4% of total 
NSP retail gas revenues.  In rate cases for Old BMG's operations in Arizona, 
NSP would need to segregate the Old BMG assets and financial results from its 
total NSP Company financial statements.  In such rate cases, NSP would also 
need to create a stand-alone, imputed capital structure for Old BMG in order 
to determine, among other things, an appropriate return on equity.

     The creation of a subsidiary also will enhance accurate allocation of 
costs to New BMG.  At the present time, NSP is segregating all operating and 
employee costs of Old BMG's operations from NSP's  other gas utility 
operations and allocating certain NSP corporate costs to the Arizona 
jurisdiction.  Yet, accounting and allocating these various segregated and 
common expenses is a difficult task, which complicates accounting for the 
costs of the North Dakota and Minnesota jurisdiction gas operations.  By 
creating a subsidiary, all direct day-to-day operating expenses of New BMG 
obviously would be reported in the stand-alone financial statements of New 
BMG.  Any services provided by NSP to New BMG would be charged-back pursuant 
to an Administrative Services Agreement between NSP and New BMG that would 
apply fully allocated costing principles to assure an appropriate allocation 
of direct and corporate costs to New BMG.


                                     5

<PAGE>

     As part of this restructuring and completion of its acquisition of the 
Old BMG operations, NSP is also seeking the approval of the Securities and 
Exchange Commission ("SEC") under the Public Utility Holding Company Act of 
1935, as amended.  SEC approval is contingent upon approval of the 
restructuring of BMG's operations into New BMG by this Commission.

     Appendix 1 provides the proposed accounting entries for the transfer of 
the Old BMG assets and liabilities of NSP to New BMG.  The transaction will 
occur at "book value," and NSP will experience no gain or loss associated 
with the transfer.  The pooling of interests approved in Docket No. 
PU-400-98-118 is not affected.

V.   IMPACT ON NSP AND ITS CUSTOMERS

     The transactions will not change the operations of NSP-ND or the 
provision of electric or natural gas service to North Dakota customers.  The 
transfers will have no material immediate or direct impact on the rates and 
other tariffs of NSP-ND on file with and approved by the Commission, and will 
provide for better financial management of the Arizona gas operations, and 
thus less complex financial management (and thus jurisdictional accounting) 
for the North Dakota and Minnesota jurisdiction gas operations.  The transfer 
would thus serve the public interest and should be approved.  

VI.  REQUESTED COMMISSION ACTION

     Based on all of the information provided in this Petition, NSP-ND 
respectfully requests the Commission find the proposed transfer is consistent 
with the public interest and should be approved.  The Parties desire to close 
the transfer and related transactions at the earliest possible date.  
Approval by mid-April 1999 would facilitate timely completion of the 
transaction.

 NORTHERN STATES POWER COMPANY FOR        
 APPROVAL OF A TRANSFER OF GAS            PETITION FOR APPROVAL OF TRANSFER OF
 UTILITY TO A NEWLY INCORPORATED          CC&N, GAS UTILITY ASSETS, WAIVER OF
 SUBSIDIARY AND AFFILIATED INTEREST       COMPLIANCE WITH A.A.C. R14-2-803, AND
 AGREEMENTS.                              APPROVAL OF AFFILIATED INTEREST
                                          AGREEMENTS


I.     INTRODUCTION AND SUMMARY

       Pursuant to Ariz. Rev. Stat. Section 40-285 and related Arizona 
Administrative Code Rules, A.A.C. R14-2-803 and A.A.C. R14-2-806, Northern 
States Power Company ("NSP" or the "Company") d/b/a Black Mountain Gas 
Company requests that the Arizona Corporation Commission ("Commission"):  (1) 
approve the transfer of its certificate of convenience and necessity 
("CC&N"), gas utility assets and related liabilities previously owned by 
Black Mountain Gas Company of Arizona to a newly-formed subsidiary of NSP, 
which will be named Black Mountain Gas Company ("New BMG"); (2) waive 
compliance with A.A.C. R14-2-803 for NSP and its affiliates, except to the 
extent that an organization or reorganization under 
                                     
<PAGE>


the rule would involve New BMG or any subsidiary subject to the jurisdiction 
of this Commission; and (3) enter an order indicating that the Commission 
approval of an Administrative Services Agreement and a Tax Sharing Agreement 
(the "Agreements") between NSP and the New BMG is not required or, 
alternatively, approve the Agreements.  NSP proposes that the new Agreements 
be effective on the date New BMG becomes an operating subsidiary of NSP, 
proposed to be May 1, 1999.  Approval of the transfer is necessary because 
NSP provides public utility gas service within Arizona.

       A.     PRIOR TRANSACTION

       On December 29, 1997, NSP and Black Mountain Gas Company, an Arizona 
corporation ("Old BMG") entered into a Merger Agreement.  The structure of 
the transaction was for Old BMG to be merged directly into NSP with NSP as 
the survivor and Old BMG ceasing to exist.  At the time of executing the 
Merger Agreement, NSP believed that such structure was appropriate and 
required to effectuate the acquisition of Old BMG under the Federal Public 
Utility Holding Company Act (PUHCA).  All regulatory filings associated with 
the merger were premised on this structure.  This Commission approved the 
merger of Old BMG into NSP by Decision No. 61009,

                                     -2-
<PAGE>

dated July 16, 1998, in Docket Nos. G-03493A-98-0017 and G-01970A-98-0017.

       B.     PROPOSED TRANSACTION

       In hindsight, NSP realizes that the corporate structure chosen was not
necessarily the best structure.  For the reasons explained below, NSP believes
the Old BMG operations should be conducted through a wholly-owned subsidiary and
not as part of the direct utility operations of NSP.  For this reason, NSP is
requesting that the Commission issue an Order approving NSP's transfer of the
CC&N and gas utility assets associated with the former operations of Old BMG to
a newly-formed subsidiary, New BMG.  This transfer will benefit the customers of
New BMG in Arizona, simplify Commission regulation of New BMG, and allow New BMG
to operate more autonomously and at lower cost.  Thus, the proposed transaction
will serve the public interest.

Further, pursuant to A.A.C. R14-2-806, NSP requests that NSP and its affiliates
be granted a waiver from the provisions of certain requirements set forth in
A.A.C. R14-2-803, except for those transactions that would involve the New BMG
or any subsidiary subject to the jurisdiction of this Commission.  The unique
circumstances of NSP, its affiliated entities and the New BMG are 

                                     -3-
<PAGE>


such that the public interest justifies such a waiver.  Finally, NSP requests 
that the Commission determine that its approval of the Agreements attached to 
this Petition is not required or, alternatively, approve the Agreements.  
NSP's Arizona utility operations will not be adversely affected by these 
transactions. NSP respectfully requests expedited review of this Petition and 
seeks approval by mid-April, 1999, so the transaction may be completed by 
May 1, 1999.

II.    GENERAL FILING INFORMATION

              This Petition is being filed on January 25, 1999.  NSP requests
              approval of the proposed transfer and the Agreements effective on
              the date New BMG becomes an operating subsidiary of NSP, proposed

III.   THE LEGAL STANDARDS FOR REVIEW

       Ariz. Rev. Stat. Section 40-285, A.A.C. R14-2-803, and A.A.C. R14-2-806
govern the Commission's review of this Petition.  A.A.C. R14-2-803(C) provides
that:
       
       At the conclusion of any hearing on the organization or reorganization of
       a utility holding company, the Commission may reject the proposal if it
       determines that it would impair the financial status of the public
       utility, otherwise prevent it from attracting capital at fair and
       reasonable terms, or impair the ability of the public utility to provide
       safe, reasonable and adequate service.

A.A.C. R-14-2-806(B) further provides that:
       
       Any affected entity may petition the Commission for a waiver by filing a
       verified application for waiver setting forth with specificity the
       circumstances whereby the public interest justifies noncompliance with
       all or part of the provisions of this Article.

       In this Petition, NSP will demonstrate that the transactions fully comply
with the requirements of these Arizona statutes and rules and are consistent
with the public interest.  The Parties are undertaking these transactions to
create a corporate structure that will be better for NSP, its customers and the
customers of New BMG in Arizona.  The Parties have structured the transactions
so that NSP's Arizona utility operations will not be adversely effected.

IV.    THE PARTIES

       NSP is an investor-owned gas and electric utility incorporated in the
state of Minnesota.  Its historic service 

                                     -7-
<PAGE>


area includes parts of Minnesota, Wisconsin, Michigan, North Dakota and South 
Dakota.  NSP (Minnesota) currently provides natural gas utility service to 
approximately 400,000 customers in Minnesota, North Dakota and South Dakota.  
NSP recently established a retail gas operation in South Dakota, and is 
presently serving less than 10 transportation-only customers pursuant to a 
tariff on file with the South Dakota PUC, Docket NG97-21, pending approval.  
NSP also provides electric utility service to about 1.3 million customers in 
these same states.  NSP (Wisconsin), a wholly-owned subsidiary of NSP, 
provides gas and electric service to approximately 300,000 customers in 
Wisconsin and Michigan.

       In addition to its utility businesses, NSP, through various 
subsidiaries, is engaged in non-utility businesses.  NRG Energy, Inc. 
("NRG"), a Delaware corporation, is a wholly-owned subsidiary of NSP that 
builds, acquires, owns and operates, either directly or indirectly, through 
subsidiaries, certain energy-related businesses.  Among these businesses are 
the ownership of 25.37% interest in the Australian State of Victoria's Loy 
Yang A power plant, a 33% interest in the coal mining, power generation and 
associated operations of Mitteldutsche Braunkohlengesellschaft mbH, located 
south of Leipzig, Germany and the ownership of a 37.5% interest in the 
Gladstone Power Station, a coal-fired plant in Gladstone, Queensland, 
Australia, which an NRG subsidiary also operates.

       NSP's other subsidiaries include Viking Gas Transmission 

                                     -8-
<PAGE>

Company ("Viking"), an interstate gas pipeline serving Minnesota, North 
Dakota and Wisconsin; Energy Masters International, Inc., an energy services 
company; Eloigne Company, which invests in affordable housing projects that 
qualify for low-income housing tax credits under federal tax law; and Seren 
Innovations, Inc., which provides certain telecommunications services.

       New BMG will be a newly-formed subsidiary of NSP.  It will be a
corporation incorporated in the State of Minnesota.  It will be the recipient of
the transfer of NSP's CC&N, gas utility assets and associated liabilities in
Maricopa County and Coconino County, Arizona, and will be engaged in business as
a local gas distribution company there.  New BMG's assets, liabilities and
operations are intended to be virtually identical to the assets, liabilities and
operations of Old BMG had it continued in existence as a subsidiary of NSP and
had not been merged into NSP.  New BMG's Cave Creek division will serve about
5,000 natural gas customers in areas in and around Cave Creek, Carefree, Phoenix
and Scottsdale.  Its Page Division will serve about 1,300 customers in the City
of Page through underground distribution of propane vapor.  New BMG will also
provide propane service to an area in Coconino County, Arizona, through a
subsidiary, Lake Powell Propane.

V.     PETITION FOR APPROVAL OF CC&N AND ASSET TRANSFER

       By an Agreement dated December 29, 1997, NSP and Old BMG agreed to merge
into a single company, with NSP as the survivor.  The Agreement contemplated a
"pooling of interests" merger.  As 

                                     -9-
<PAGE>


explained previously, NSP has realized that it would be more appropriate to 
have the Old BMG operations conducted through a subsidiary on a long-term 
basis.  The purpose of this application is to seek the requisite authority to 
cause the NSP operations of Old BMG to be transferred to such subsidiary.

       There are several concerns with the current structure under which the 
Old BMG operations are conducted directly by NSP.  The division structure 
imposes an unnecessary level of complexity to the Commission and NSP in 
regulating the Old BMG operations and will require NSP to present various 
issues to the Commission that are irrelevant to Arizona gas ratepayers.  For 
example, under A.R.S. Section 40-301(2), NSP would appear to need Commission 
approval to issue securities even if the proceeds of the securities are to 
finance NSP's electric operations in Minnesota, and thus have no bearing on 
gas service in Arizona. New BMG will focus on serving Arizona gas customers, 
and will allow the Commission to focus only on Arizona operations.

       In addition, the Old BMG operations make up only 1.4% of total NSP
natural gas customers, 3% of total NSP gas investment, and 1.4% of total NSP
retail gas revenues.  In rate cases for Old BMG's operations in Arizona, NSP
would need to segregate the Old BMG assets and financial results from its
financial statements.  In such rate cases, NSP might also need to create a
stand-alone, imputed capital structure for Old BMG in order to determine, among
other things, an appropriate return on equity.

       The creation of a subsidiary also will enhance accurate 

                                     -10-
<PAGE>


allocation of costs to New BMG.  At the present time, NSP is segregating all 
operating and employee costs of Old BMG's operations from NSP's other gas 
utility operations and allocating certain NSP corporate costs to the Arizona 
jurisdiction.  Yet, accounting and allocating these various segregated and 
common expenses is a difficult task that complicates accounting for the costs 
of the other jurisdiction gas operations.  By creating a subsidiary, all 
direct day-to-day operating expenses of New BMG would be reported in the 
stand-alone financial statements of New BMG.  Any services provided by NSP to 
New BMG would be charged back pursuant to an Administrative Services 
Agreement between NSP and New BMG that would be approved, if necessary, by 
this Commission.

       As part of this restructuring and completion of its acquisitions of the
Old BMG operations, NSP is also seeking the approval of the Securities and
Exchange Commission ("SEC") under the Public Utility Holding Company Act of
1935, as amended.  SEC approval is contingent upon approval of the restructuring
of BMG's operations into New BMG by this Commission.

       Appendix A provides the proposed accounting entries for the transfer of
the Old BMG assets and liabilities of NSP to New BMG.  The transaction will
occur at "book value," and NSP will experience no gain or loss associated with
the transfer.

VI.    PETITION FOR WAIVER OF A.A.C. R14-2-803

       On September 29, 1998, NSP filed an application for a waiver of
compliance with the Commission's Affiliated Interest Rules.

                                     -11-
<PAGE>


In Decision No. 61211, Docket No. G-03493A-98-0562, October 29, 1998, the 
Commission denied the application for a complete waiver, granting a limited 
waiver [i.e., partial waivers of A.A.C. R14-2-805(A) and (A)(3), A.A.C. 
R14-2-805(A)(4), A.A.C. R14-2-805(A)(6), A.A.C. R14-2-805(8), A.A.C. 
R14-2-805(10), and A.A.C. R14-2-805(11)] and determined not to waive A.A.C. 
R14-2-803 because the Commission found, in part, that NSP was not a public 
utility holding company within the meaning of the rules.  The Commission 
noted that if NSP ever restructured to become or form a holding company, the 
provisions of A.A.C. R-14-2-803 would apply.  SEE Decision No. 61211 at 
Finding of Fact PARA 14.

       Following completion of the transfer of Old BMG's operation to New 
BMG, NSP will be a holding company under A.A.C. R14-2-803 and, therefore, NSP 
again requests a waiver of that rule, except as to an organization or 
reorganization of the New BMG or any other subsidiary subject to the 
Commission's jurisdiction. NSP incorporates its request for waiver filed on 
September 28, 1998 as if fully set forth herein.

       As discussed above, the Old BMG operations make up only 1.4% of total NSP
natural gas customers, 3% of total NSP gas investment, and 1.4% of total NSP
retail gas revenues.  Of the more than two million customers served by NSP, only
7,000 are residents of Arizona.  Of the over $2.7 billion revenue NSP reported
at the end of 1997, only $6 million came from Arizona operations.

       In addition to being under the jurisdiction of the 

                                     -12-
<PAGE>


Commission, retail sales rates, services and other aspects of NSP's 
operations are subject to the jurisdiction of the Minnesota Public Utilities 
Commission (the "MPUC"), the North Dakota Public Service Commission (the 
"NDPSC") and the South Dakota Public Utilities Commission (the "SDPUC") 
within their respective states.  The MPUC also possesses regulatory authority 
over aspects of NSP's financial activities, including security issuances, 
property transfers within the state of Minnesota when the asset value is in 
excess of $100,000, mergers with other utilities, and transactions between 
the regulated Company and its regulated and non-regulated affiliates.  
NSP-Wisconsin is subject to regulation of similar scope by the Public Service 
Commission of Wisconsin ("PSCW") and the Michigan Public Service Commission 
("MPSC").

Wholesale rates for electric energy sold in interstate commerce, wheeling rates
for energy transmission in interstate commerce, the wholesale gas transportation
rates of Viking, and certain other aspects of NSP, NSP-Wisconsin, and Viking are
subject to the jurisdiction of the Federal Energy Regulatory Commission
("FERC").  NSP also is subject to the jurisdiction of other federal, state, and
local environmental agencies in many of its activities.

       NSP is fully cognizant of its responsibility to the Commission and the
attendant obligations as a regulated entity to submit to the requirements of
lawful regulation.  However, NSP respectfully submits that the unique
circumstances of NSP and its 
                                     -13-
<PAGE>

 . . . . .

affiliated entities are such that the public interest justifies a Waiver of
Compliance with A.A.C. R14-2-803.

       A.A.C. R14-2-803 requires prior Commission approval for any utility or
affiliate intending to organize a public utility holding company or reorganize
an existing public utility holding company.  The term "reorganize" is defined in
R14-2-801 as "[t]he acquisition or divestiture of a financial interest in an
affiliate or a utility, or reconfiguration of an existing affiliate or utility's
position in the corporate structure or the merger or consolidation of an
affiliate or a utility."  If literally applied to the NSP family of companies,
prior Commission approval would be necessary for any transaction in which a
subsidiary of NSP was either created or dissolved, or which might result in a
"reconfiguration of an existing affiliate or utility's position in the corporate
structure."  The scope of a prior approval requirement based upon this
definition could result in several hundred transactions being submitted to the
Commission for prior approval even though such transactions had absolutely no
effect on NSP's Arizona gas utility operations.

       The sheer volume of the effort required to prepare the notice of intent
required by A.A.C. R14-2-803 and the subsequent analysis by the Commission and
its Staff would create an unreasonable burden for both NSP and the Commission
Staff, particularly since the jurisdictional New BMG operations would not be
affected by the filing.  Moreover, requiring any affiliate 

                                     -14-
<PAGE>


of NSP to secure the approval of the Commission for a transaction which does 
not, in any way, involve NSP or the State of Arizona would have the 
inevitable effect of seriously impeding the normal conduct of business by NSP 
entities on both an interstate and international basis.

       As discussed previously, NSP is comprehensively regulated by the MPUC,
the NDPSC, the SDPUC, as well as the PSCW, MPSC and FERC.  This comprehensive
regulatory scheme ensures that NSP's activities are carefully scrutinized. 
However, the fact that NSP is regulated in multiple jurisdictions clearly
indicates the potentially adverse consequences of strict application of the
Commission's Affiliated Interest Rules.  Such a result could virtually paralyze
not only NSP but NSP's various regulated subsidiaries (NSPW and Viking) even
though the activities are utility in nature and have no nexus to regulated gas
services in the State of Arizona.

       An asserted basis for extending Commission jurisdiction into unrelated
activities of NSP or any of its affiliates is the potential impact that such
activities could have upon New BMG's cost of capital, thereby having an effect
on Arizona operations and ratepayers.  However, the creation of the independent
operations of a New BMG would, in fact, insulate New BMG from the potential
impacts.  Moreover, New BMG will be an extremely small portion of NSP's overall
operations.  As such, indirect impacts on the financial condition of the larger
NSP parent would have negligible (if any) effects on New BMG's subsidiary
operations.
                                     -15-

  . . . . .

This separation and protection to Arizona ratepayers provides a logical policy
reason to approve the proposed transaction.

VII.   PETITION FOR APPROVAL OF AFFILIATED INTEREST AGREEMENTS

       Following completion of the transfer of Old BMG's operations to New 
BMG, NSP and New BMG will be affiliated interests under Ariz. Rev. Stat. 
Section 40-285 and A.A.C. R14-2-803.  The parties thus would enter into 
certain Agreements to define the terms of their relationship.  NSP believes 
that these Agreements do not require Commission approval and asks the 
Commission to so declare. Alternatively, NSP hereby requests approval of an 
Administrative Services Agreement and a Tax Sharing Agreement with New BMG.

       Appendix B contains certain documentation required by A.A.C. R14-2-803,
including a copy of the Agreements in Attachment 2-A.

       As a result of the NSP/Old BMG merger, NSP provides various corporate and
other services to its retail gas operations in Arizona and makes an internal (to
NSP) allocation of costs to the Arizona gas operation, just as NSP provides an
internal allocation to its retail gas operations in North Dakota.  The cost of
service in the pending BMG gas rate reduction case includes this allocation to
NSP's Arizona gas operations in the test year cost of service.

       As a result of the proposed transfer to New BMG, the internal NSP cost
allocation will be replaced by a charge-back via the Administrative Services
Agreement ("ASA").  The proposed Administrative Service Agreement provides a
contractual mechanism 
                                     -16-
<PAGE>


whereby NSP and New BMG can provide various services to each other in order 
to take advantage of efficiencies and economies of scale and charge each 
other on a fully-allocated cost basis.  Consistent with NARUC methods, the 
MPUC requires fully allocated  cost allocations between NSP and regulated and 
non-regulated operations.  This obligation is bilateral, so charge-backs by 
New BMG to NSP would also use fully allocated costing methods. The Tax 
Sharing Agreement ("TSA") will allow NSP and New BMG to reflect the impacts 
of NSP's consolidated corporate tax return, and is similar to numerous TSAs 
between NSP and subsidiaries.

       The Agreements are proposed to be effective on the date New BMG is
established as an operating subsidiary of NSP, proposed to be May 1, 1999.  The
Agreements may be terminated by either party on 60 days notice thereafter.

       In order to minimize the risk that the Commission and the MPUC reach
conflicting decisions, the ASA and TSA are being filed for review and approval
by the MPUC contemporaneously with the instant filing.  If requested, NSP will
share pertinent materials from the MPUC proceeding with the Commission and
parties to this proceeding.

VIII.  THE TRANSACTIONS ARE IN THE PUBLIC INTEREST

       The transactions will not change the provision of natural gas service 
to Arizona customers.  The transfers will have no material, immediate or 
direct impact on NSP's pending gas rate reduction application (Docket No. 
G-3493-98-0705) and other tariffs of NSP on file with and approved by the 
Commission, and 
                                     -17-
<PAGE>

will provide for better financial management of the Arizona gas operations.  
The transfers would thus serve the public interest and should be approved.

        Moreover, waiver of A.A.C. R14-2-803 for NSP and its affiliates 
(except as related to the organization or reorganization of the New BMG or 
any affiliate thereafter subject to the jurisdiction of this Commission) will 
also serve the public interest.  Finally, the proposed Administrative 
Services Agreement and Tax Sharing Agreements should also be approved because 
they satisfy the requirements of Ariz. Rev. Stat. Section  40-285 and A.A.C. 
R14-2-801 ET SEQ.  Thus the proposed transfer, waiver, and, to the extent 
necessary, the Agreements should be approved.
