Item 1.  DESCRIPTION OF PROPOSED TRANSACTION

A.   INTRODUCTION

          This Application/Declaration seeks approvals relating to the proposed
combination of Public Service Company of Colorado ("PSCo") and Southwestern
Public Service Company ("SPS"), pursuant to which PSCo and SPS will become
wholly-owned subsidiaries of New Century Energies, Inc. ("NCE"), a new Delaware
holding company (the "Transaction").  Following the consummation of the
Transaction, NCE will register with the Securities and Exchange Commission (the
"Commission") as a holding company under the Public Utility Holding Company Act
of 1935 (the "Act").

          The Transaction is expected to produce substantial benefits to the
public, investors and consumers, and meets all applicable standards of the Act. 
Among other things, PSCo and SPS believe that the Transaction will allow the
shareholders of each of the companies to participate in a larger, financially
stronger company that, through a pooling of the equity, management, human
resources and technical expertise of each company, will be able to achieve
increased financial stability and strength, greater opportunities for earnings
and dividend growth, reduction of operating costs, deferral of certain capital
expenditures, efficiencies of operation, better use of facilities for the
benefit of customers, seasonal diversity of demand, improved ability to use new
technologies, greater retail and industrial sales diversity, and improved
capability to make wholesale power purchases and sales.  In this regard, PSCo
and SPS believe that synergies created by the Transaction will generate
substantial cost savings to NCE that would not be available absent the
Transaction.  PSCo and SPS have estimated the dollar value of certain synergies
resulting from the Transaction to be approximately $770 million, net of costs to
achieve the savings, over the first 10-year period from 1997 to 2006.  The
expected Transaction benefits are discussed in further detail in Item 3.A.2.b.i.
below.
 
          The shareholders of PSCo and SPS both approved the Transaction at
their respective meetings held on January 31, 1996.  PSCo and SPS have submitted
applications requesting approval of the Transaction and/or related matters to
(i) the Public Utilities Commission of the State of Colorado (the "CPUC"),
(ii) the New Mexico Public Utility Commission (the "NMPUC"), (iii) the Public
Service Commission of the State of Wyoming (the "WPSC"), (v) the Public Utility
Commission of the State of Texas ("PUCT"), (vi) the Kansas Corporation
Commission (the "KCC"), (vii) the Federal Energy Regulatory Commission (the
"FERC") and (viii) the Nuclear Regulatory Commission (the "NRC").  The following
regulatory agencies have approved the Transaction:  the KCC in a written order
issued November 28, 1995, and in a written order issued December 3, 1996; the
NRC in a letter dated February 22, 1996; the WPSC in an oral bench decision on
May 30, 1996, which was subsequently confirmed in a written order issued on
August 16, 1996; the CPUC in an oral decision on August 23, 1996, which was
subsequently confirmed in a written 

<PAGE>

decision issued on November 26, 1996, and in a decision on rehearing issued 
January 15, 1997; the NMPUC in a written decision issued on January 28, 1997; 
the PUCT in a written decision on February 14, 1997; and the FERC in a 
decision issued on March 12, 1997.  Finally, both companies made the required 
filings with the Antitrust Division of the U.S. Department of Justice (the 
"DOJ") and the Federal Trade Commission (the "FTC") under the 
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR 
Act") on August 22, 1996.  The required thirty-day waiting period expired on 
September 21, 1996.  See Item 4 below for additional detail regarding these 
regulatory approvals.  Apart from the approval of the Commission under the 
Act, all required regulatory approvals have been obtained.  The foregoing 
approvals are the only regulatory 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, NCE requests that the 
Commission's review of this Application/Declaration proceed as expeditiously 
as practicable.

     1.   GENERAL REQUEST

          Pursuant to Sections 9(a)(2) and 10 of the Act, NCE hereby requests 
authorization and approval of the Commission to acquire, by means of the 
mergers described below, all of the issued and outstanding common stock of 
PSCo, SPS, and Cheyenne Light, Fuel and Power Company ("Cheyenne"), a Wyoming 
public utility company and currently a wholly-owned subsidiary of PSCo.  NCE 
also hereby requests that the Commission approve (i) the acquisition by NCE 
of all of the outstanding voting securities of New Century Services, Inc. 
("NC Services"), NC Enterprises, Inc. ("NC Enterprises"), West Gas 
Interstate, Inc. ("WGI"), a subsidiary of PSCo that is engaged in the gas 
transportation business, (1) and PS Colorado Credit Corporation ("PSCCC"), a 
subsidiary of PSCo that finances (factors) certain of PSCo's current assets,
under Section 9(a)(1) of the Act; (ii) the acquisition by NC Enterprises of 
securities of all of SPS's and certain of PSCo's non-utility subsidiaries 
under Section 9(a)(1) of the Act; (iii) the acquisition by NCE, NC 
Enterprises, or e prime, inc. ("e prime"), a subsidiary of PSCo which is to 
become a subsidiary of NC Enterprises, of all of the outstanding voting 
securities of New Century International, Inc. ("NC International"); (iv) NC 
Services as a subsidiary service company in accordance with the provisions of 
Rule 88 of the Act and the Utility Service Agreement and the Non-Utility 
Service Agreement as a basis for NC Services to comply with Section 13 of the 
Act and the Commission's rules thereunder; (v) certain additional affiliate 
transactions as being in accordance with the provisions of Section 13 of the 
Act; and (vi) the issuance of NCE Common Stock in connection with the 
Transaction.

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

(1)  WGI is regulated by the FERC, but is not a public-utility company within 
the meaning of the Act.

     2.   OVERVIEW OF THE TRANSACTION

          Pursuant to an Agreement and Plan of Reorganization, dated as of
August 22, 1995, as amended on December 8, 1995 (the "Merger Agreement"), PSCo
Merger Corp., a Colorado corporation and a wholly-owned subsidiary of NCE ("PSCo
Merger Corp."), will be merged with and into PSCo, with PSCo continuing as the
surviving corporation (the "PSCo Merger"), and SPS Merger Corp., a New Mexico
corporation and a wholly-owned subsidiary of NCE, will be merged with and into
SPS, with SPS as the surviving corporation (the "SPS Merger").  As a result of
the PSCo Merger and the SPS Merger, and the declaration of a dividend by PSCo to
NCE of all of the stock of Cheyenne, PSCo, SPS, and Cheyenne will become
operating subsidiaries of NCE, and NCE will be a holding company within the
meaning of the Act.

          In addition, WGI will become a direct subsidiary of NCE and NC
International may become a direct subsidiary of NCE (by the declaration of a
dividend by PSCo to NCE of WGI's and NC International's stock), as will NC
Services and NC Enterprises (newly formed corporations).  PSCCC will also become
a direct subsidiary of NCE by a declaration of a dividend by PSCo of PSCCC's
stock.  Upon consummation of the Transaction, the non-utility subsidiaries and
investments of SPS will become subsidiaries and investments of NC Enterprises,
and certain of the non-utility subsidiaries of PSCo will become direct and
indirect subsidiaries of NC Enterprises, certain others will remain subsidiaries
of PSCo (as described below), and one, NC International, may become a direct
subsidiary of NCE, or alternatively a direct or indirect subsidiary of NC
Enterprises.  NCE is also requesting approval of the terms of (1) the Utility
Service Agreement (described below in Item 3.B.2), and (2) the Non-Utility
Service Agreement (also described below in Item 3.B.2).  NCE is also requesting
approval of the acquisition by NC Enterprises of securities, directly and
indirectly, of certain of the non-utility subsidiaries, affiliates, and
investments of PSCo and of SPS.  The two SPS subsidiaries, Quixx Corporation
("Quixx") and Utility Engineering Corporation ("UE") will be transferred through
the sale by SPS of all of the outstanding common stock of such subsidiaries to
NC Enterprises in exchange for debt of NC Enterprises.  The subsidiaries of PSCo
to be transferred to NC Enterprises, including NC International if NCE
ultimately determines that it should be placed directly or indirectly under NC
Enterprises, will be transferred by a declaration of a dividend of their stock
to NCE and subsequent capital contribution of their stock to NC Enterprises or a
subsidiary thereof.  A chart of the proposed corporate structure of NCE
following consummation of the Transaction is attached hereto as Exhibit E-6.

          The common shareholders of PSCo and SPS will receive one and 0.95 of
one share of common stock, par value of $1.00 per share, of NCE ("NCE Common
Stock"), respectively, and will become common shareholders of NCE (see Item
1.C.2 below).  The Transaction will have no effect on the shares of preferred
stock of PSCo and SPS issued and outstanding at the time of the consummation of
the Transaction, each series of which and each share of which will remain

                                  -3-

unchanged.  SPS presently has no shares of preferred stock outstanding.  A copy
of the Merger Agreement is incorporated by reference as Exhibit B-1 hereto.

although small portions of two jointly-owned lines are located in New Mexico and
Nebraska, both along the Colorado border.  As of December 31, 1996, PSCo's
transmission system consisted of approximately 112 circuit miles of 345 KV
overhead lines; 1,916 circuit miles of 230 KV lines; 15 circuit miles of 230 KV
underground lines; 65 circuit miles of 138 KV overhead lines; 999 circuit miles
of 115 KV underground lines; 20 circuit miles of 115 KV underground lines; 344
circuit miles of 69 KV overhead lines; 143 circuit miles of 44 KV overhead
lines; and 1 circuit mile of 44 KV underground lines.  PSCo jointly owns with
other utilities approximately 342 circuit miles of 345 KV overhead lines and 360
miles of 230 KV overhead lines, of which PSCo's share is 112 miles and 147
miles, respectively, which shares are included in the amounts referred to above.

          The system is interconnected with the systems of the following
utilities with which PSCo has major firm purchase power contracts; capacity and
energy are provided primarily by generating sources in the locations indicated:

<TABLE>

<S>                                <C>
Utility                            Location

Basin Electric Power Cooperative   Southeast Wyoming
PacifiCorp                         West & Northwest U.S.
                                   Northwest Colorado
Platte River Power Authority       Northcentral Colorado
Tri-State                          Southeast Wyoming and
                                   Northwest Colorado

</TABLE>

          PSCo has wheeling agreements with the above, and with other utilities
and public power agencies, which are utilized to provide capacity and energy to
PSCo's system from time to time.

          PSCo's transmission system also interconnects with the system of the
Western Area Power Administration ("WAPA").

          PSCo is a member of the Western Systems Coordinating Council (the
"WSCC"), an interstate network of transmission facilities that are owned by
public entities and investor-owned utilities.  WSCC is the regional reliability
council providing planning and coordination for member electric power systems in
the Western United States.  PSCo is also a member of the Western Systems Power
Pool (the "WSPP") which is an economic power pool that operates an electronic
bulletin board and acts as a clearinghouse for bulk power transactions among
over 90 member utilities and marketers.  The WSPP Agreement, to which PSCo is a
signatory, originally provided for the sale and purchase of capacity, energy and
transmission services 

                                   -13-

<PAGE>

at market-based rates with a cost-based floor and ceiling.(5)  The WSPP 
Agreement was amended and refiled to comport with the transmission 
requirements of FERC Order No. 888, PROMOTING WHOLESALE COMPETITION THROUGH 
OPEN ACCESS NON-DISCRIMINATORY TRANSMISSION SERVICES BY PUBLIC UTILITIES 
(issued April 24, 1996) ("FERC Order No. 888").

          Cheyenne owns two 115 KV transmission line segments that total 25.5
miles in length that fall within and are operated by WAPA's Loveland control
area.

               iv.  GAS FACILITIES

          The gas property of PSCo at December 31, 1996 consisted chiefly of
approximately 15,304 miles of distribution mains ranging in size from 0.50 to 30
inches and related equipment.  The Denver distribution system consisted of 8,691
miles of mains.

          The gas property of Cheyenne at December 31, 1996 consisted chiefly of
approximately 551 miles of distribution/transmission mains ranging in size from
1 to 16 inches and related equipment.

               v.   OTHER

          PSCo owns and operates four underground gas storage facilities: 
Roundup, Asbury, Fruita (all conventional depleted gas reservoirs), and Leyden
(a converted mined cavern).  These combined facilities have a maximum working
volume of 18,974,000 Mcf, and a maximum daily send out capacity of 252,000 Mcf/
day.

          PSCo's steam heating property at December 31, 1996 consisted of 10.5
miles of transmission, distribution, and service lines in the business district
of Denver, including a steam transmission line connecting the steam heating
system with PSCo's Zuni electric power plant.  Steam is supplied from boilers
installed at PSCo's Denver Steam Plant, which has a capability of 295,000 pounds
of steam per hour under sustained load.  An additional 300,000 pounds of steam
per hour is available from PSCo's Zuni electric generating plant on a peak
demand basis.  PSCo also owns service and office facilities in Denver and other
communities located throughout its service territory.

          In addition PSCo and its subsidiaries own other property, plant, and
equipment supporting their electric and gas utility functions.

          Transactions with the SPP are handled through interties near Elk City
and Guymon, Oklahoma, and Shamrock and Oklaunion, Texas.  These interties allow
SPS to sell energy to or to purchase energy from the eastern electrical grid. 
Sales through eastern interties accounted for 2.0%, 1.0%, and 1.0% of fiscal
1995, fiscal 1996, and calendar year 1996 total sales, respectively.

          HVDC interconnections link SPS with the western electrical grid of the
United States.  SPS purchases and sells energy through HVDC interties near
Artesia and Clovis, New Mexico.  Sales through these interties accounted for
4.1%, 3.2%, and 4.1% of fiscal 1995, fiscal 1996, and calendar year 1996 total
sales, respectively.

               iv.  OTHER

          In addition, SPS and its subsidiaries own property, plant and
equipment supporting their electric utility functions.

     3.   NON-UTILITY

          a.   PSCo

          PSCo presently has nine direct non-utility subsidiaries.(6)  Eight of
these subsidiaries are wholly-owned:  WGI, e prime, NC International, 1480 
Welton, PSCCC, PSRI, Fuelco, and Green and Clear Lakes.  PSCo owns 80.03% of 
the capital stock of Natural Fuels.  WGI is a natural gas transmission 
company operating in Colorado and Wyoming (see Item I.B.1.c.vi.); e prime 
directly or indirectly offers energy related products and services to 
energy-using customers and to selected segments of the utility industry, and

has been formed to hold a 50% interest in Yorkshire Electricity Group plc(7) and
other investments in EWGs and FUCOs; Fuelco has been engaged in the 
exploration for, and the development and production of, natural gas and oil, 
principally in Colorado, but now is a corporation in dissolution under 
Colorado law; 1480 Welton is a real estate company which owns certain of 
PSCo's real estate interests for use in its utility business; PSRI owns and 
manages company owned life insurance (COLI) policies on certain past and 
present employees, the benefits from which are to provide future funding for 
general corporate purposes; PSCCC is a company that finances (factors) 
certain of PSCo's current assets; Green and Clear Lakes owns water rights and 
storage facilities for water used at PSCo's Georgetown Hydroelectric Station; 
and Natural Fuels sells compressed natural gas as a transportation fuel to 
retail markets, converts vehicles for natural 

- ----------------------
(6)  Prior to the consummation of the Transaction, PSCo also expects to 
establish a new ETC.  See note 4, SUPRA.

(7)  In an order issued on February 19, 1997, in File No. 70-8985, the 
Commission authorized PSCo to acquire its indirect interest in Yorkshire 
Electricity Group plc pursuant to Section 3(b) of the Act and Rules 10 and 11 
thereunder.

gas usage, constructs fueling facilities, and sells miscellaneous fueling 
facility equipment.

          e prime has the following direct subsidiaries and investments:  Young
Gas, a wholly-owned subsidiary, which holds a 47.5% interest in a limited
partnership which owns an underground gas storage facility; Texas Ohio Gas, a
wholly-owned subsidiary, which provides natural gas and retail electric
marketing services; Texas Ohio Pipeline, a wholly-owned subsidiary, which owns
and operates a 900 foot interstate gas pipeline linking the pipelines of Texas
Eastern Corporation and Tennessee Gas Pipeline; ep3 (of which e prime holds a
20% general partnership interest and a 30% limited partnership interest), which
was formed to engage, or invest, in the business of marketing, developing,
financing, constructing, managing and operating, electrical energy transmission,
distribution or generation facilities or providing consulting services related
thereto, in Latin America and other emerging foreign markets; Johnstown
Cogeneration, a limited liability company (of which e prime has a 50% ownership
interest), which owns a 3 MW QF located in Johnstown, Colorado; e prime Telecom,
which will provide long-haul fiber capacity on a wholesale basis to non-
associate companies and seek qualification as an ETC under Section 34 of the Act
and the Federal Communications Commission's ("FCC") regulations implementing
that section; e prime Networks, which will provide remote meter reading services
to PSCo and other utilities using a fixed network; e prime international, which
has been formed to hold investments in EWGs and FUCOs and presently has a 25%
interest in Kazak Power Partners Limited, which owns the Karaganda Steam Power
Station GRES 2 ("Karaganda II"), an EWG located in Topar, Kazakstan, and which
wholly owns e prime operating, inc., which has entered into a contract to
operate Karaganda II and intends to operate other EWGs; e prime (Belize)
Limited, which has been formed to acquire an interest in an EWG in
Belize; 8 and e prime Marketing, which has been formed to engage in the electric
and gas marketing activities that e prime is currently engaging in directly.

          NC International owns a 50% interest in Yorkshire Power Group Limited,
which through a wholly-owned subsidiary Yorkshire Holdings plc, has completed a
tender offer to acquire Yorkshire Electricity Group plc, a regional electric
company operating in the United Kingdom.  PSCo has obtained authorization from
the Commission to acquire the contemplated interest in Yorkshire Electricity
Group plc.  See File No. 70-8985.  After the consummation of the Transaction, NC
International will become a wholly-owned subsidiary of e prime, of NC
Enterprises, or of NCE directly. It will not remain a subsidiary of PSCo except
during an interim period.  After such transfer from PSCo to one of these
affiliates, Yorkshire Electricity Group plc will be qualified as a FUCO under
Section 33 of the Act.  

- --------------------
(8)  It is not presently expected that e prime (Belize) Limited will actually 
acquire an interest in the project, and therefore it may be dissolved in the 
near future.


                                      -18-


<PAGE>

It is presently contemplated that NC International may acquire interests in or 
operate other FUCOs. (9)

          Natural Fuels has the following direct subsidiaries and investments: 
A 50% ownership interest in Natural/Total Limited Liability Company
("Natural/Total"), a Wyoming L.L.C., which owns and operates natural gas fueling
stations located at Total Petroleum Gas Stations in Colorado; a 50% profits
interest (25% capital interest) in Natural/Peoples Limited Liability Company, a
Wyoming L.L.C., which owns and operates one natural gas fueling station located
in Castle Rock, Colorado; and a 67% ownership interest through Natural/Total in
Natural/Total/KN Limited Partnership, which owns the profits interests in the
natural gas fueling stations located at Total Petroleum sites in the Colorado
towns of Grand Junction and Glenwood Springs.

          PSCo holds a greater than 50% interest in several other relatively
small ditch and water companies:  namely, East Boulder Ditch Company, Hillcrest
Ditch and Reservoir Company, United Water Company, Consolidated Extension Canal
Company, Enterprise Ditch Company, and Las Animas Consolidated Canal Company. 
PSCo also holds a less than 50% interest in the following small ditch and water
companies:  namely, Fisher Ditch Water Company, Bough Lateral Ditch Company,
Beenan Irrigating Ditch and Milling Company and Jones and Donelley Ditch
Company.  (These companies are collectively referred to as the "Ditch
Companies.")  These Ditch Companies' capital requirements are not significant
and are not consolidated in PSCo's financial statements or statistical
data. 10  Each of these ditch and irrigation companies was acquired for the 
purpose of providing cooling water for generation facilities.  All but two of 
them are currently utilized in that capacity.  The remaining two companies are 
being held in anticipation of the need to build additional generation facilities
in the future.

          Together, at December 31, 1996, and at December 31, 1995, PSCo's
investments in its non-utility subsidiaries constituted less than four percent
of the consolidated book value of the assets of both PSCo and its subsidiaries.

          A corporate chart of PSCo and its subsidiaries, showing their
non-utility interests, is filed as Exhibit E-4.

- --------------------
(9)  PSCo through NC International (or alternatively e prime) expects to acquire
prior to the closing of the Transaction for $2 million a minority interest in 
Independent Power Corporation PLC ("IPC"), a British company that is in the 
business of developing, owning, and operating foreign generating plants.

(10) The aggregate revenues of the five Ditch Companies in which PSCo holds a 
50% or greater interest at December 31, 1996 were $144,270. Their aggregate 
assets at that time were $148,170.


                                      -19-


<PAGE>

          A discussion of the bases on which the businesses of these
subsidiaries may be retained is set forth in Item 3.A.2.a.

          b.   SPS

          SPS wholly owns two direct non-utility subsidiaries, UE and Quixx.  No
assets of Quixx or UE are presently, or will following the consummation of the
Transaction be, included in the rate base of any public utility company within
the NCE system.  UE is a wholly-owned subsidiary formed in 1986.  It is engaged
in a variety of engineering, development, design, procurement, construction and
other related services.  UE also owns twenty-five electric substations.  These
substations are leased to twelve industrial customers of SPS.  UE employs
approximately 120 employees.  In addition, it is contemplated that approximately
fifty-five to seventy-five employees of PSCo will be transferred to UE upon
consummation of the Transaction.  UE's assets at December 31, 1996, and
December 31, 1995, were approximately $47.8 million and $43.4 million,
respectively, and total revenues for calendar years 1996 and 1995 were
$21.1 million and $29.8 million, respectively.  UE is primarily involved in
projects for nonaffiliate customers, providing general engineering, development,
design, procurement, construction and other related services.  SPS is one of
UE's major clients.  UE also works jointly with Quixx on cogeneration and other
independent power and related projects, providing such services.  It is intended
that UE will service primarily unaffiliated customers, and for fiscal 1996 and
calendar 1996, approximately $14.7 million and $14.1 million, or 69.5% and
66.7%, respectively, of UE's revenues were derived from unaffiliated customers.

          Quixx is a wholly-owned subsidiary formed in 1986.  Its primary
business is investing in and developing cogeneration and energy-related
projects.  In 1996, Quixx invested $9.8 million in such projects.  Quixx
operates, as a division, Amarillo Railcar Services, a railcar maintenance
facility that provides inspection, light and heavy maintenance, and storage for
unit trains.  A majority of these services are provided for railcars that
transport coal for use by SPS.  In addition, Quixx has royalty interests in coal
and other minerals produced and to be produced from certain New Mexico
properties owned by the Pittsburgh and Midway Coal Mining Company.  Quixx also
finances sales of heat pumps and markets other non-utility goods and services. 
Quixx employs approximately 45 employees.  Quixx's assets at December 31, 1996
and December 31, 1995 were approximately $80.6 million and $86.0 million,
respectively, and total revenues for calendar years 1996 and 1995 were
$18.0 million and $19.7 million, respectively.

          UE owns 49% of Vista Environmental.  Vista Environmental performs
environmental consulting services, client-regulatory interfacing, site
assessments, due diligence, waste management planning, remedial action design
and implementation, groundwater valuation, mineral surveys, and on-site field
supervision in both the private and governmental sectors and is providing site
remediation services, and will continue to provide site remediation and other


                                      -20-


<PAGE>

services, to SPS and may in the future provide such services to NCE's utility
subsidiaries and non-utility subsidiaries and affiliates.  Annual revenues to UE
from Vista Environmental are approximately $675,000.  UE's investment in Vista
Environmental is $175,000.

          UE currently has two wholly-owned subsidiaries:  Utility Services, and
PRC.

          Utility Services provides services related to the engineering, design,
procurement, and construction of cooling towers for power plants, as well as
plant construction, distribution, operation and maintenance activity, resource
recovery, and wood product fabrication (cooling tower components and utility
pole crossarms)to unaffiliated parties.  Such services may also be provided to
utility and non-utility subsidiary companies and affiliates.  Utility Services
contracts with SPS for personnel to perform transmission substation operations
and maintenance for third parties.  Following the Transaction, these
transactions for personnel will be made in accordance with the requirements of
Rules 87, 90, and 91 under the Act.

          PRC provides a technical personnel resource database service.  Its
database is comprised of names of unaffiliated individuals with technical
expertise who can be dispatched to provide temporary services for various
projects to associate companies and unaffiliated parties.

          Quixx has nine wholly-owned subsidiaries, eight of which hold
partnership interests in various energy-related limited partnerships.  In
addition, Quixx directly holds interests in four other entities. 11  The
following is a description of Quixx's subsidiaries and investments:

          Quixx holds a 42% limited partnership interest in BCH Energy Limited
Partnership ("BCH"), which owns a waste-to-energy facility located near
Fayetteville, North Carolina.  The operation of the BCH facility has been
suspended.  The Facility provided steam to a Du Pont De Nemours & Company ("Du
Pont") plant near Fayetteville and electric power to Carolina Power & Light
Company.  In December of 1996, because of the operational problems that rendered
the project not economically viable, Quixx wrote off approximately $16 million,
representing its entire investment in the project.

- --------------------
(11)  Such entities do not include Lindsay Cogeneration, L.P.  At the time
of the filing of the initial Application/Declaration, Quixx had an additional
investment entitled Lindsay Cogeneration, L.P.  Notice of dissolution of that
partnership was sent to the partnership on December 27, 1996, and the
dissolution will be effective on March 27, 1997, at which time the appropriate
filings will be made with the California authorities.


                                      -21-

Colorado River Authority.

          Quixx Power Services, Inc. ("QPS"), a wholly-owned subsidiary of
Quixx, has operated and maintained the BCH facility in North Carolina and will
operate and maintain the Linden cogeneration facility and KES Jamaica facility.

          Quixx has recently entered into a memorandum of understanding with
Golden Spread Electric Cooperative, Inc. and an unaffiliated independent power
producer (the "PP") to construct a 488 MW combined cycle generating facility to
be called the Mustang Station which, subject to obtaining regulatory approvals,
would be completed by 1998.  Golden Spread and a limited partnership called
Denver City Energy Associates, L.P. ("Denver City Energy Associates") (of which
the PP and Quixx will be the general partners and in which each will have a 50%
interest) would each own a 50% undivided interest in the Station.  Quixx will
hold its interest in Denver City Energy Associates through a wholly-owned
subsidiary, Quixx Mustang Station, Inc.  The power from the Station would be
supplied principally to Golden Spread.  The Station will be interconnected with
the SPS system.  The limited partnership will be an EWG and the PP will be the
Project Manager.  UE and certain unaffiliated third parties submitted a bid in a
competitive bidding process conducted by

proposed 216 MW cogeneration plant that would be located at the Phillips
Refinery Complex near Borger, Texas.  Quixx will hold this interest through a
wholly-owned subsidiary, Quixx Borger Cogen, Inc. ("Borger CoGen"), which will
in turn be a 50% partner of Borger Energy Associates, L.P., the owner of the
plant.  Quixx will share ownership of the facility with LS Power.  The plant
will be a QF.  Construction is expected to begin in 1997 and the plant is
expected to be operational in the summer of 1998.

          Quixx has recently executed an agreement to purchase a 50% membership
interest in Mosbacher Power Group, L.L.C. and Mosbacher Power International,
L.L.C. (together the "Mosbacher Companies"), which are independent power

subsidiaries and investments may be retained is set forth in Item 3.A.2.a.

C.   DESCRIPTION OF TRANSACTION

     1.   BACKGROUND AND NEGOTIATIONS LEADING TO THE PROPOSED TRANSACTION 

          PSCo and SPS have had numerous discussions over the past several years
related to various means of better utilizing their facilities, including
pursuing possibilities to enter into joint ventures for the construction of
various generation and transmission facilities.  In addition, PSCo and SPS share
the view that fundamental changes in the electric energy industry are inevitable
and that such changes are leading to greater competition in a once monopolistic
industry.

          The Energy Policy Act of 1992 (the "1992 Act") granted the FERC the
authority to order electric utilities to provide transmission service to other
utilities and to other buyers and sellers of electricity in the wholesale
market.  The 1992 Act also created a new class of power producers, exempt
wholesale generators ("EWGs"), that are exempt from regulation under the Act. 
The exemption from regulation under the Act of EWGs has increased the number of
entrants into the wholesale electric generation market, thus increasing
competition in the wholesale segment of the electric utility industry.

          Commencing in December 1993, pursuant to its authority under the 1992
Act, the FERC issued a number of orders in specific cases directing utilities to
provide transmission services.  Under the FERC's evolving transmission policies,
utilities are being required to offer transmission services to third parties on
a basis comparable to service that the utilities provide themselves.  On
April 7, 1995, the FERC issued a notice of proposed rule making under which it
proposed to implement on a comprehensive basis the comparable transmission
service policies it has developed in specific cases.  The notice of proposed
rulemaking culminated in the issuance of FERC Order No. 888 on April 24, 1996. 
The FERC's actions to date and its transmission rulemaking proceeding have
increased the availability of transmission services, thus creating greater
competition in the wholesale power market.

          In addition, state regulatory bodies in certain states have initiated
proceedings to review the basic structure of the industry.  These bodies are
considering proposals to require some measure of competition in the retail
portion of the industry.

          With the passage of the 1992 Act and the rapidly changing utility
environment in general, both PSCo and SPS began investigating their individual
strategic options related to the new competitive landscape.  Both companies
reached the same conclusions:


                                      -24-


<PAGE>

          1.   A key to future success would be to become a quality low cost
               provider;

          2.   Size would be a key factor related to the various options that
               could be provided to meet customer demands and further reduce
               costs; and

          3.   Financial strength would be essential in the changing
               environment.

          On March 29, 1995, following an electric utility industry meeting in
Washington, D.C., senior management from both PSCo and SPS met to discuss a
variety of business opportunities the two companies could jointly pursue as part
of the changing environment, including a possible merger.

          Soon after this meeting, PSCo engaged the law firm of LeBoeuf, Lamb,
Greene & MacRae, L.L.P. ("LeBoeuf Lamb") to advise it with respect to the
potential business combination, and SPS engaged the law firm of Cahill Gordon &
Reindel ("Cahill Gordon") to advise it with respect to the potential business
combination.

          On May 12, 1995, certain PSCo employees met with certain SPS employees
to discuss, among other items, (i) the hiring of Deloitte & Touche LLP
("Deloitte & Touche") to assist the managements of PSCo and SPS in preparing a
detailed synergy analysis; (ii) establishing a timetable to investigate a
possible merger; (iii) the financial and operational modeling and analysis that
would be required; and (iv) the exchange of preliminary information requests. 
On May 12, 1995, a Confidentiality and Standstill Agreement was signed between
PSCo and SPS.  Pursuant to that agreement, the two companies and their
representatives agreed to provide non-public information to each other with a
view toward exploring a possible business combination.

          Following those preliminary discussions, PSCo engaged Barr Devlin &
Co. Incorporated ("Barr Devlin") to act as its financial advisor in connection
with a possible business combination with SPS, and SPS engaged Dillon, Read &
Co. Inc. ("Dillon Read") to act as its financial advisor in connection with the
possible business combination with PSCo.

          During the months of June, July and August of 1995, PSCo and SPS
management personnel and representatives of Deloitte & Touche had numerous
meetings in Dallas and Denver to analyze all aspects of the synergy study (e.g.,
operations and maintenance, capacity deferrals, fuel savings, and other
corporate programs).  In these meetings, PSCo and SPS management personnel, with
the assistance of Deloitte & Touche, analyzed potential savings that would be
created by the Transaction and that could not be obtained absent the
Transaction, and savings that would be accelerated as result of the merging of
the operations of the two companies.  Costs of achieving the merger-related
savings, as well as savings which were already planned to be achieved through
other means, were also identified and


                                      -25-


<PAGE>

quantified so that the synergy savings would be a "net" amount.  In addition, 
preliminary due diligence activities and financial and operating modeling 
assumptions were discussed, and conferences were held between the respective 
financial advisors and counsel with respect to merger-related matters.  In July,
representatives of LeBoeuf Lamb and Cahill Gordon began drafting the Merger 
Agreement.  Throughout this period, the Boards of Directors of PSCo and SPS 
discussed various aspects of the Transaction and the status of the negotiations.

          On August 22, 1995, the PSCo Board met to review and approve the
Mergers.  Barr Devlin rendered its written fairness opinion, provided the PSCo
Board with information supporting that opinion, and discussed in detail the
analysis underlying its opinion.  The PSCo management and its legal advisors
also made presentations reviewing the transaction, including valuation issues,
legal issues, and issues concerning the Merger Agreement and related documents. 
After the presentations, the PSCo Board approved the Merger Agreement and
related documents.

          On August 22, 1995, the SPS Board met to approve the Mergers.  SPS
management and its legal and financial advisors made presentations reviewing the
transaction (valuation, legal, Merger Agreement and related documents).  Dillon
Read delivered its fairness opinion to the SPS Board.  After the presentations,
final negotiations were held with representatives of PSCo regarding the
conversion ratio.  At the conclusion of those discussions and negotiations, the
SPS Board unanimously approved the Merger Agreement and related documents.

          On January 31, 1996, the shareholders of PSCo and SPS, respectively,
met and voted to approve the Transaction.

          Additional information regarding the background of the Transaction is
set forth in the NCE Registration Statement on Form S-4 (Exhibit C-1 hereto).

     2.   MERGER AGREEMENT

          The Merger Agreement provides for SPS Merger Corp. to be merged with
and into SPS, and PSCo Merger Corp. to be merged with and into PSCo.  The Merger
Agreement is incorporated by reference as Exhibit B-1.

          Under the terms of the Merger Agreement, upon consummation of the
Transaction:

     -    each issued and outstanding share of PSCo Common Stock, 12  together 
          with appurtenant rights, shall be converted into

- --------------------
(12)  Other than treasury and certain other shares that will be canceled, 
fractional shares and shares held by holders who dissent in compliance with 
Colorado law.


                                      -26-


<PAGE>

          the right to receive one share of NCE Common Stock (the "PSCo 
          Conversion Ratio"); 

     -    each issued and outstanding share of SPS Common Stock, 13  together 
          with appurtenant rights, shall be converted into the right to receive
          0.95 of one share of NCE Common Stock (the "SPS Conversion Ratio" and,
          together with the PSCo Conversion Ratio, the "Conversion Ratios"); 

     -    each share of PSCo Merger Corp. Common Stock issued and outstanding
          prior to the Transaction will be converted into one share of Common
          Stock of PSCo as the surviving corporation;

     -    each share of SPS Merger Corp. Common Stock issued and outstanding
          prior to the Transaction will be converted into one share of Common
          Stock of SPS as the surviving corporation; and

     -    all shares of capital stock of NCE issued and outstanding immediately
          prior to the Transaction will be canceled.

The shares of preferred stock of PSCo and any shares of preferred stock of SPS
outstanding at the time of the consummation of the Transaction will remain
preferred stock of PSCo and SPS, respectively.  The Transaction is conditioned
on being tax-free to PSCo and SPS shareholders (except as to dissenters' rights
and fractional shares.)  Based on the capitalization and the Conversion Ratios
of PSCo and SPS on December 1, 1995, the shareholders of PSCo and SPS would own
securities representing approximately 62.0% and 38.0%, respectively, of the
outstanding shares of common stock.

          The Transaction is subject to customary closing conditions, including
the receipt of the requisite shareholder approvals of PSCo and SPS and all
necessary governmental approvals, including the approval of the Commission.

          The Transaction is designed to qualify as a tax-free reorganization
under Section 351 of the Internal Revenue Code of 1986, as amended.  PSCo and
SPS believe that the Transaction will be treated as a "pooling of interests" for
accounting purposes.

D.   PSCo AND SPS BENEFIT PLANS

          PSCo and SPS currently have eight plans which involve the issuance of
shares of the companies' common stock to participating employees, or, in the
case of dividend reinvestment plans, 

- --------------------
(13)  Other than those shares that will be canceled, fractional shares and 
shares held by holders who dissent in compliance with New Mexico law.


                                      -27-


<PAGE>

shareholders.  They are as follows:  the PSCo Employee Savings and Stock 
Ownership Plan, the PSCo Omnibus Incentive Plan, the PSCo Automatic Dividend 
Reinvestment and Common Stock Purchase Plan, the SPS Directors' Deferred 
Compensation Plan, the SPS 1989 Stock Incentive Plan, the SPS Employee 
Investment Plan, the SPS Dividend Reinvestment and Cash Payment Plan for 
Employees, and the SPS Dividend Reinvestment and Cash Payment Plan for 
Shareholders.

          It is anticipated that for an undetermined period of time after the
consummation of the Transaction all such PSCo and SPS plans, except the 
dividend reinvestment plans, the PSCo Omnibus Incentive Plan, and the SPS 
1989 Stock Incentive Plan, will be maintained on substantially the same 
terms, except that shares of NCE Common Stock will be used instead of PSCo 
Common Stock and SPS Common Stock.  It is also anticipated that the PSCo 
Dividend Reinvestment Plan and the two SPS Dividend Reinvestment Plans will 
be terminated in connection with the consummation of the Transaction to be 
replaced by an NCE dividend reinvestment plan (the "NCE DRIP").  NCE filed a 
separate Form U-1 Application/Declaration (File No. 70-9007) seeking 
authorization from the Commission as required in connection with NCE shares 
to be issued in financing transactions following consummation of the 
Transaction, including shares to be issued under the PSCo or the SPS plans or 
the NCE DRIP.  In such Form U-1, NCE system companies also requested 
authorization for various financing transactions and for the retention of a 
financing entity, Southwestern Public Service Capital I.(14)

          At some point subsequent to the consummation of the Transaction, it 
is intended that certain stock-based plans of NCE (the "NCE Stock-Based 
Benefit Plans") will replace the PSCo or SPS benefit plans with a similar 
name.  It is intended that each of the NCE Stock-Based Benefit Plans will 
contain substantially the same provisions as the existing PSCo or SPS plans 
with similar name.  The NCE Stock-Based Benefit Plans may be adopted and 
approved by PSCo and SPS, as the shareholders of NCE, prior to the 
consummation of the Transaction. NCE has sought authorization from the 
Commission as required in connection with NCE shares to be issued under the 
NCE Stock Based Benefit Plans in the above-referenced filing (File 
No. 70-9007).

E.   MANAGEMENT AND OPERATIONS OF NCE FOLLOWING THE MERGER

          Pursuant to the Merger Agreement, the NCE Board consists of fourteen
members, eight designated by PSCo and six by SPS.  Upon consummation of the 
Transaction, the NCE Board of Directors shall have four committees as 
follows: an audit committee, a compensation committee, a finance committee, 
and a nominating and civic responsibility committee.  PSCo and SPS each shall 
designate the 

- -------------------
(14) Applicants also request that SPS be authorized to retain Southwestern 
Public Service Capital I, a wholly-owned trust, that issued the trust 
preferred securities and loaned proceeds to SPS.  (Refer to SPS's historical 
capital structure in Item 3.A.1.d.)

                                    -28-

<PAGE>

chairmen of two of these committees. In addition to the chairmen, each 
committee shall consist of two members designated by PSCo and two members 
designated by SPS.  The Merger Agreement provides that for four and one-half 
years following consummation of the Transaction, these arrangements 
concerning the NCE Board of Directors and its committees may not be modified 
unless the terms of such modification are approved by a vote of two-thirds of 
the NCE Board of Directors.

          Mr. Helton is Chairman of the Board of Directors and Chief Executive
Officer of NCE and Mr. Brunetti is NCE's Vice-Chairman of the Board, 
President and Chief Operating Officer.  Mr. Helton and Mr. Brunetti each have 
an employment agreement with NCE.  The forms of these employment agreements 
are attached as Annexes VI and VII to NCE's Registration Statement on Form 
S-4, incorporated by reference herein as Exhibit C-1.  In addition, persons 
have been selected to serve as officers of NCE and certain of its 
subsidiaries following consummation of the Transaction.

          The Merger Agreement provides that NCE shall maintain (i) its
corporate offices in Denver, Colorado and (ii) significant operating offices 
in Amarillo, Texas.  Such provision cannot be modified for four and one-half 
years following the consummation of the Transaction unless the terms of such 
modification are approved by a vote of two-thirds of the NCE Board of 
Directors.

          Following consummation of the Transaction, the activities of NCE will
be governed by its Restated Certificate of Incorporation and Restated Bylaws,
attached hereto as Exhibits A-1 and A-2 respectively.

A.   LEGAL ANALYSIS

          Section 9(a)(2) 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)(A), 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."

          PSCo, SPS, and Cheyenne are public utility companies as defined in
Section 2(a)(5) of the Act.  Because NCE will acquire more 

                                    -31-

<PAGE>

than five percent of the voting securities of each of PSCo, SPS, and Cheyenne 
as a result of the Transaction, and because PSCo, SPS, and Cheyenne will 
become "affiliates" of NCE as a result of the Transaction, NCE must obtain 
the approval of the Commission for the Transaction under Sections 9(a)(2) and 
10 of the Act.  The statutory standards to be considered by the Commission in 
evaluating the proposed transaction are set forth in Sections 10(b), 10(c), 
and 10(f) of the Act.

          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.  Thus:

     -    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 NCE 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; 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 Applicants' analysis and would facilitate the creation of a new holding 
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,"(15) should be used in reviewing this Application/Declaration 
since, as demonstrated below, the Transaction will benefit both consumers and 
shareholders of NCE and the other federal and state regulatory authorities 
with jurisdiction over this Transaction have approved it as in the public 
interest.  In addition, although discussed in more detail in each applicable 
item below, the specific recommendations of the Division with regard to 
financing

transactions,(16) utility ownership,(17) and diversification(18) are 
applicable to this Transaction.

     1.   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 interests of investors or
     consumers;

          (2)  in 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 interests of investors or consumers or the proper
     functioning of such holding company system.

financings.  1995 Report at 50. 

(17)  E.g., the Commission should apply a more flexible interpretation of the 
integration requirements under the Act; interconnection through power pools, 
reliability councils, and wheeling arrangements can satisfy the physical 
interconnection requirement of section 2(a)(29); the geographic requirements 
of section 2(a)(29) should be interpreted flexibly, recognizing technical 
advances consistent with the purposes and provisions of the Act; the 
Commission's analysis should focus on whether the resulting system will be 
subject to effective regulation; the Commission should liberalize its 
interpretation of the "A-B-C" clauses and permit combination systems where 
the affected states agree, and the Commission should "watchfully defer" to 
the work of other regulators.  1995 Report at 71-7.

(18)  E.g., the Commission should promulgate rules to reduce the regulatory 
burdens associated with energy-related diversification and the Commission 
should adopt a more flexible approach in considering all other requests to 
enter into diversified activities.  1995 Report at 88-90.

          a.   SECTION 10(b)(1)

               i.   INTERLOCKING RELATIONSHIPS

          By its nature, any merger results in new links between previously
unrelated companies.  However, these links are not the types of interlocking
relationships targeted by Section 10(b)(1), which was primarily aimed at
preventing business combinations unrelated to operating synergies.

          The Merger Agreement provides for the Board of Directors of NCE to be
composed of members drawn from the Boards of Directors of both PSCo and SPS. 
This is necessary to integrate PSCo and SPS fully into the NCE system and will
therefore be in the public interest and the interests of investors and
consumers.  Forging such relations is beneficial to the protected interests
under the Act and thus is not prohibited by Section 10(b)(1).

               ii.  CONCENTRATION OF CONTROL

          Section 10(b)(1) is intended to avoid "an excess of concentration and
bigness" while preserving the "opportunities for economies of scale, the
elimination of duplicate facilities and activities, the sharing of production
capacity and reserves and generally more efficient operations" afforded by the
coordination of local utilities into an integrated system.  American Electric
Power Co., 46 SEC 1299, 1309 (1978).  In applying Section 10(b)(1) to utility
acquisitions, the Commission must determine whether the acquisition will create
"the type of structures and combinations at which the Act was specifically
directed."  Vermont Yankee Nuclear Corp., 43 SEC 693, 700 (1968).  As discussed
below, the PSCo-SPS strategic alliance will not create a "huge, complex, and
irrational system," but rather will afford the opportunity to achieve economies
of scale and efficiencies which are expected to benefit investors and consumers.
American Electric Power Co., 46 SEC 1299, 1307 (1978).

          Size:  If approved, the NCE system will serve approximately
1.5 million electric customers in six states and 980,000 gas customers in
Colorado and Wyoming.  As of and for the twelve months ended December 31, 1996,
for PSCo and SPS:  (1) the combined assets of PSCo and SPS would have totaled
approximately $7 billion; (2) combined operating revenues of PSCo and SPS would
have totaled approximately $3.0 billion; and (3) combined owned generating
capacity would have totaled approximately 7,438 MW.

          By comparison, the Commission has approved a number of acquisitions
involving significantly larger operating utilities.  See, e.g., CINergy Corp.,
HCAR No. 26146 (Oct. 21, 1994) (combination of The Cincinnati Gas & Electric Co.
and PSI Resources; combined assets at time of acquisition of approximately
$7.9 billion); Entergy Corp., HCAR No. 25952 (Dec. 17, 1993) (acquisition of
Gulf States Utilities Companies; combined assets at time of acquisition in
excess of $21 billion); Northeast Utilities, HCAR No. 25221 (Dec. 21, 1990)
(acquisition of Public Service of New Hampshire; combined assets at 

                             -34-
<PAGE>

time of acquisition of approximately $9 billion); The Southern Company, HCAR 
Nos. 24579 and 24579A (February 12, 1988 and February 26, 1988, respectively) 
(acquisition of Savannah Electric and Power Company; combined assets at time 
of acquisition of approximately $20 billion); Centerior Energy Corp., HCAR 
No. 24073 (April 29, 1986) (combination of Cleveland Electric Illuminating 
and Toledo Edison; combined assets at time of acquisition of approximately 
$9.1 billion); American Electric Power Co., 46 SEC 1299 (1978) (acquisition 
of Columbus and Southern Ohio Electric; combined assets at time of 
acquisition of approximately $9 billion).

          As the following table demonstrates, seven of the fifteen registered
electric utility holding company systems are larger than NCE will be following
the Transaction in terms of assets, operating revenues, customers, and/or sales
of electricity:(19)

Northeast          10,545             3,749          1,694           39,618 
CINergy             8,220             3,031          1,369           54,220 
NCE                 6,018             2,881          1,476           44,229 

          In addition, NCE will be smaller than two of the registered holding
companies to be formed as a result of recently announced mergers, specifically
the merger of Wisconsin Energy Corp. and Northern States Power Company (combined
1995 year-end assets of approximately $10.6 billion and operating revenues of
$4.4 billion) and Union Electric Company and CIPSCO, Inc. (combined as of
June 30, 1996, assets of approximately $8.6 billion and operating revenues of
$3.0 billion).

          NCE will be a mid- to small-size registered holding company, and its
operations would not exceed the economies of scale of current electric
generation and transmission technology or provide undue power or control to NCE
in the region in which it will provide service.

          Efficiencies and economies:  As noted above, the Commission has
rejected a mechanical size analysis under Section 10(b)(1) in favor of assessing
the size of the resulting system with reference to the efficiencies and
economies that can be achieved through the integration and coordination of
utility operations.  More recent pronouncements of the Commission confirm that
size is not determinative.  Thus, in Centerior Energy Corp., HCAR No. 24073
(April 

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

(19)  Amounts are as of December 31, 1995 or for the year ended December 31, 
1995.

<PAGE>

29, 1986), the Commission stated flatly that a "determination of whether to 
prohibit enlargement of a system by acquisition is to be made on the basis of 
all the circumstances, not on the basis of size alone."  In addition, in the 
1995 Report, the Division recommended that the Commission approach its 
analysis on merger and acquisition transactions in a flexible manner with 
emphasis on whether the Transaction creates an entity subject to effective 
regulation and is beneficial for shareholders and customers as opposed to 
focusing on rigid, mechanical tests.(20)

          By virtue of the Transaction, NCE will be in a position to realize the
"opportunities for economies of scale, the elimination of duplicate facilities
and activities, the sharing of production capacity and reserves and generally
more efficient operations" described by the Commission in American Electric
Power Co. 46 SEC at 1309.  Among other things, the Transaction is expected to
yield significant capital expenditure savings through the deferral or
elimination of certain capacity requirements and a reduction in reserve margin;
savings through greater purchasing power; labor cost savings; administrative and
general savings; and cost-of-capital savings.  These expected economies and
efficiencies from the combined utility operations are described in greater
detail below and are projected to result in net savings of approximately
$770 million over the first ten years alone.

          Competitive Effects:  As the Commission noted in Northeast Utilities,
HCAR No. 25221 (Dec. 21, 1990), the "antitrust ramifications of an acquisition
must be considered in light of the fact that public utilities are regulated
monopolies and that federal and state administrative agencies regulate the rates
charged consumers."  On August 22, 1996, PSCo and SPS filed Notification and
Report Forms with the DOJ and FTC pursuant to the HSR Act describing the effects
of the Transaction on competition in the relevant market and no request for
additional information was received before the expiration of the applicable
thirty-day waiting period on September 21, 1996.  It is a condition to the
consummation of the Transaction that the applicable waiting periods under the
HSR Act shall have expired or been terminated, which condition has been
satisfied.

          In addition, the competitive impact of the Transaction has been fully
considered by the FERC in connection with its approval of the merger of PSCo and
SPS.  A detailed explanation of the reasons why the Transaction will not
threaten competition in even the most narrowly drawn geographic and product
markets is set forth in the prepared testimony of Dr. Robert Spann, filed with
the FERC on behalf of PSCo and SPS, a copy of which is filed as Exhibit D-1.2.1.
The application filed by PSCo and SPS with the FERC is filed as Exhibit D-1.1. 
PSCo and SPS have entered into a settlement agreement with various intervenors
resolving all issues in that proceeding, including market power issues.  The
FERC Trial Staff has submitted comments 

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

(20)  1995 Report at 73-4.

                             -36-
<PAGE>

supporting that settlement agreement. In his order certifying the settlement 
to the FERC for review and decision, a Presiding Administrative Law Judge 
rejected the claim of the intervenor opposing the settlement agreement that 
the Transaction raised disputed issues of material fact regarding the 
Transaction's competitive effects.  In fact, the Presiding Administrative Law 
Judge found that "Staff and Applicants have shown that the merger is not 
anti-competitive, and, in fact, may be pro-competitive."  On that basis, he 
certified the settlement agreement without an initial decision.  On March 12, 
1997, the FERC issued an order approving the merger.  Filed herewith as 
Exhibit D-1.4, Exhibit D-1.5, and Exhibit D-1.6, respectively, are copies of 
the FERC settlement agreement, the Certification of Contested Settlement 
Agreement in the FERC proceeding, and the FERC's order.  See Item 4.B. for 
additional detail.

          For these reasons, the Transaction will not "tend toward interlocking
relations or the concentration of control" of public utility companies, of a
kind or to the extent detrimental to the public interest or the interests of
investors or customers within the meaning of Section 10(b)(1).

          b.   SECTION 10(b)(2) -- FAIRNESS OF CONSIDERATION

          Section 10(b)(2) requires the Commission to determine whether the
consideration to be given by NCE to the holders of PSCo Common Stock and SPS
Common Stock in connection with the Transaction is reasonable and whether it
bears a fair relation to investment in and earning capacity of the utility
assets underlying the securities being acquired.(21)  Market prices at which 
securities are traded have always been strong indicators as to values.  As shown
in the table below, most quarterly price data, high and low, in the years 1994, 
1995, and 1996, for PSCo and SPS Common Stock provide support for this 
conversion ratio.




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

(21)  The shares of PSCo preferred stock and any SPS preferred stock 
outstanding at the time of the consummation of the Transaction will remain 
outstanding preferred stock of PSCo and SPS, respectively.

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

*    The information is provided for calendar quarters.  Fiscal quarters for SPS
end on the last day of each November, February, May and August.

          On August 22, 1995, the last full trading day before the public
announcement of the execution and delivery of the Merger Agreement, the closing
price per share on the NYSE Consolidated Tape of (i) PSCo Common Stock was 
$31 1/2 and (ii) SPS Common Stock was $29 3/8, a ratio of 1 to 0.93.

          The fairness of the Transaction's consideration is also evidenced 
by the fact that the Transaction is a pure stock-for-stock exchange and 
qualifies for treatment as a pooling of interests for accounting 
purposes.(22)   As set forth more fully above, each share of

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

(22)  Twelve specific conditions must be met to qualify as a pooling.  The 
Transaction should meet those criteria as follows:  (1) Both PSCo and SPS 
were autonomous and were not a subsidiary or division of another corporation 
within two years before the plan of combination was initiated; (2) At the 
date of the merger initiation and at the date of consummation SPS and PSCo 
are independent of each other; (3) SPS and PSCo will undertake a course of 
action which will attempt to complete the transaction within one year in 
accordance with a specific plan, or completed in a single transaction.  
Litigation or proceedings of a governmental authority that delay the 
completion of a plan are excepted from the one-year rule, provided they are 
beyond the control of the combining companies; (4) At the consummation date 
of the plan, NCE will offer and issue its majority class of stock (voting 
rights) for no less than 90% of the voting common stock interests of SPS and 
PSCo.  The 90%, or more of the voting common stock interests being acquired 
is determined at the date the plan is consummated; (5) No changes in the 
equity interests of the voting common stock of
                                                                 (continued...)

                                     -38-
<PAGE>

PSCo Common Stock will be converted into the right to receive one share of NCE 
Common Stock, and each share of SPS Common Stock will be converted into the 
right to receive 0.95 of one share of NCE Common Stock. The Transaction will 
therefore involve no "acquisition adjustment" or other write-up of the assets of
SPS or PSCo.

          In addition, the Conversion Ratios are the product of extensive and
vigorous arms-length negotiations between PSCo and SPS.  These negotiations were
preceded by months of due diligence, analysis, and evaluation of the assets,
liabilities and business prospects of each of the respective companies.  See NCE
Registration Statement on Form S-4 (Exhibit C-1 hereto).

          Finally, nationally-recognized investment bankers for each of PSCo and
SPS have reviewed extensive information concerning the companies and analyzed
the Conversion Ratios employing a variety of valuation methodologies, and have
opined that the Conversion Ratios are fair, from a financial point of view, to
the respective holders of PSCo Common Stock and SPS Common Stock.  The
investment bankers' analyses and opinions are attached as Annexes II and III to
NCE's Registration Statement on Form S-4 and are described on pages 33-43 of the
Form S-4 (Exhibit C-1 hereto).

          In light of these opinions and an analysis of all relevant factors,
including the benefits that may be realized as a result of the Transaction, NCE
believes that the Conversion Ratios fall 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 PSCo and SPS. 

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

(22) (...continued)
SPS or PSCo were to be made in contemplation of a pooling of interests.  This 
restriction is for a period beginning two years prior to the initiation date 
of the plan of combination and for the period between the initiation date and 
the consummation date; (6) SPS and PSCo will not reacquire any of its voting 
common stock in substance or form to effect a business combination.  Any 
reacquisition must be a normal amount as evidenced by both companies' 
patterns of reacquisition prior to the merger; (7) Each SPS and PSCo common 
stockholder will receive a voting common stock interest exactly in proportion 
to his or her voting common stock interest prior to the combination; (8) The 
SPS and PSCo common shareholders will receive the rights they are entitled to 
and will not be deprived or restricted in any way from exercising those 
rights; (9) The entire merger agreement will be effected on the date of 
consummation; (10) Subsequent to consummation the combined corporation, NCE, 
will not agree to reacquire or retire any of the stock which was issued to 
effect the transaction; (11) NCE will not enter into any agreements to the 
benefit of the former shareholders of SPS or PSCo, such as loan guarantees; 
(12) NCE will not plan to dispose of substantial amounts of the assets of SPS 
or PSCo within two years of the date of the combination other than routine 
transactions in the ordinary course of business or to eliminate excess 
capacity.

          c.   SECTION 10(b)(2) -- REASONABLENESS OF FEES

          NCE believes that the overall fees, commissions and expenses incurred
and to be incurred in connection with the Transaction are reasonable and fair in
light of the size and complexity of the Transaction relative to other
transactions and the anticipated benefits of the Transaction to the public,
investors, and consumers; that they are consistent with recent precedent; and
that they meet the standards of Section 10(b)(2).

          As set forth in Item 2 of this Application/Declaration, PSCo and SPS
together incurred a combined total of approximately $23.5 million in fees,
commissions and expenses in connection with the Transaction.  By contrast,
Cincinnati Gas & Electric Company and PSI Resources incurred $47.12 million in
fees in connection with their reorganization as subsidiaries of CINergy,
Northeast Utilities alone incurred $46.5 million in fees and expenses in
connection with its acquisition of Public Service of New Hampshire, and Entergy
alone incurred $38 million in fees in connection with its recent acquisition of
Gulf States Utilities -- which amounts all were approved as reasonable by the
Commission.  See CINergy, HCAR No. 26146 (Oct. 21, 1994); Northeast Utilities,
HCAR No. 25548 (June 3, 1992); Entergy Corp., HCAR No. 25952 (Dec. 17, 1993).

          With respect to financial advisory fees, PSCo and SPS believe that the
fees payable to their investment bankers are fair and reasonable for similar
reasons.

          Pursuant to the terms of Barr Devlin's engagement, PSCo paid Barr
Devlin for its services in connection with the Transaction:  (i) a financial
advisory retainer fee of $100,000 upon signing the June 5, 1995 engagement
letter; (ii) an initial financial advisory progress fee of $1,000,000 upon
execution of the Merger Agreement; and (iii) a second financial advisory
progress fee of $1,000,000 upon PSCo shareholder approval of the Merger
Agreement.  In addition, PSCo has agreed to pay Barr Devlin a transaction fee
based on the aggregate consideration to be received by SPS and holders of SPS
Common Stock in connection with the Transaction on the consummation of the
Transaction, ranging from 0.45 percent of such aggregate consideration (for a
transaction with an aggregate consideration of $1,000,000,000) to 0.41 percent
of such aggregate consideration (for a transaction with an aggregate
consideration of $2,000,000,000).  All retainer fees payable during the term of
the engagement and all financial advisory progress fees would be credited
against any transaction fee payable to Barr Devlin.  PSCo has agreed to
reimburse Barr Devlin for its out-of-pocket expenses, including fees and
expenses of legal counsel and other advisors engaged with the consent of PSCo,
and to indemnify Barr Devlin against certain liabilities, including liabilities
under the federal securities laws, relating to or arising out of its engagement.

          Pursuant to the engagement letter between SPS and Dillon Read, SPS has
paid Dillon Read the following amounts:  $200,000 upon the execution of the
engagement letter , $450,000 upon the rendering of Dillon Read's fairness
opinion to the SPS Board, $200,000 upon the affirmative vote of SPS shareholders
in favor of the Transaction, and $100,000 on April 30, 1996, and $100,000 every
six months thereafter until the Transaction is consummated or Dillon Read's
engagement has been terminated.  SPS has also agreed to pay Dillon Read a fee
upon consummation of the Transaction equal to 0.37 percent of the aggregate
amount of consideration received by SPS's common shareholders, less the $850,000
and the $100,000 semi-annual payments mentioned above which will have previously
been paid.  SPS has agreed to reimburse Dillon Read for its out-of-pocket
expenses, including fees and expenses of legal counsel and other advisors
engaged with the consent of SPS, and to indemnify Dillon Read against certain
liabilities, including liabilities under the federal securities laws, relating
to or arising out of its engagement.

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

          d.   SECTION 10(b)(3)

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

          Capital structure:  The corporate capital structure of NCE after the
Transaction will not be unduly complicated and will be substantially similar to
capital structures approved by the Commission in other orders.  See, e.g.,
CINergy, HCAR No. 26146 (Oct. 21, 1994); Centerior Energy Corp., HCAR No. 24073
(April 29, 1986); Midwest Resources, et al., HCAR No. 25159 (Sept. 26, 1990);
Entergy Corp., HCAR No. 25952 (Dec. 17, 1993); Northeast Utilities, HCAR
No. 25548 (June 3, 1992).

          In the Transaction, the shareholders of PSCo and SPS will receive NCE
Common Stock.  NCE will own 100% of the common stock of PSCo and SPS and there
will be no minority common stock interest remaining in either company.  Each
share of PSCo and any share of SPS preferred stock outstanding at the time of
the consummation of the Transaction will remain outstanding preferred stock of
PSCo and SPS, respectively.  The debt securities of PSCo and SPS outstanding at
the time of the consummation of the Transaction will likewise remain outstanding
without change.  The only voting securities of NCE which will be publicly held
after the transaction will be NCE Common Stock.  NCE will have the ability to
issue, subject to the approval of the Commission, preferred stock, the terms of
which, including any voting rights, may be set by NCE's Board of Directors as
has been authorized by the Commission with regard to other registered holding
companies.  See, e.g., The Columbia Gas System, Inc., HCAR No. 26361 (Aug. 25,


                                     -41-
<PAGE>

1995) (approving restated charter, including preferred stock whose terms, 
including voting rights, can be established by the board of directors).  NCE 
filed a separate Form U-1 Application/Declaration (File No. 70-9005) seeking 
authorization to declare a dividend distribution of one right for each share 
of NCE common stock, entitling the holder to purchase securities of NCE in 
certain events.  The only class of voting securities of NCE's direct 
non-utility subsidiaries will be common stock.  Moreover, with respect to 
NCE's second-tier non-utility subsidiaries, in all but one case (NCE will 
hold 80.03% of the common stock of Natural Fuels), all issued and outstanding 
shares of voting securities will be held by either NC Enterprises or PSCo.  
In addition, NC Enterprises will have issued debt to SPS in connection with 
its acquisition of the outstanding voting securities of Quixx and UE as more 
fully described in Item 3.A.4.ii below.

          Set forth below are summaries of the historical capital structure of
PSCo and SPS as of December 31, 1996, and the pro forma consolidated capital
structure of NCE as of that date:

     * The pro forma consolidated capital structure of NCE has been adjusted
       to reflect future nonrecurring charges directly related to the
       Transaction, which result in, among other things, the recognition of
       additional current liabilities and a reduction in retained earnings.

NCE's pro forma consolidated common equity to total capitalization ratio of 45%
comfortably exceeds the "traditionally acceptable 30% level."  Northeast
Utilities, 47 SEC Docket at 1279, 1284 (1990).

          Protected interests:  As set forth more fully in Item 3.A.2.b.i
(Efficiencies and Economies), Item 3.A.2.b.ii (Integrated Public Utility System)
and elsewhere in this Application/Declaration, the Transaction is expected to
result in substantial cost savings and synergies, and will integrate and improve
the efficiency of the PSCo and SPS utility systems.  The Transaction will
therefore be in the public interest and the interests of investors and
consumers, and will not be detrimental to the proper functioning of the
resulting holding company system.

     2.   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(23); or

- -------------------------
     (23) By their terms, Sections 8 and 11 only apply to registered holding
     companies and are therefore inapplicable at present to NCE, since it is not
     now a registered holding company. The following discussion of
                                                       (continued...)


                                     -43-
<PAGE>


     (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 . . . .

          a.   SECTION 10(c)(1)

          Section 10(c)(1) requires that an acquisition be lawful under
Section 8.  Section 8 prohibits registered holding companies from acquiring,
owning interests in or operating both a gas and an electric utility serving
substantially the same area if state law prohibits it.  As discussed below, the
Transaction does not raise any issue under Section 8 or, accordingly, the first
clause of Section 10(c)(1).  Indeed, Section 8 indicates that a registered
holding company may own both gas and electric utilities where, as here, the
relevant state utility commissions support such an arrangement.

          Section 10(c)(1) also requires that an acquisition not be detrimental
to carrying out the provisions of Section 11.  Section 11(a) of the Act requires
the Commission to examine the corporate structure of registered holding
companies to ensure that unnecessary complexities are eliminated and voting
powers are fairly and equitably distributed.  As described above, the
Transaction will not result in unnecessary complexities or unfair voting powers.

          Although Section 11(b)(1) generally requires a registered holding
company system to limit its operations "to a single integrated public utility
system, and to such other businesses as are reasonably incidental, or
economically necessary or appropriate to the operations of such integrated
public utility system," a combination integrated gas and electric system within
a registered holding company is permissible under Section 8.  Additionally,
Section 11(b)(1) provides that "one or more additional integrated public utility
systems" may be retained if, as here, certain criteria are met. 
Section 11(b)(2) directs the Commission "to ensure that the corporate structure
or continued existence of any company in the holding company system does not
unduly or unnecessarily complicate the structure, or unfairly or inequitably
distribute voting power among security holders, of such holding company system."

          As detailed below, the Transaction will not be detrimental to the
carrying out of the provisions of Section 11.

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

     (23)(...continued)
     Sections 8 and 11 is included only because, under the present transaction
     structure, NCE will register as a holding company after consummation of the
     Transaction.

                       i.   RETENTION OF GAS OPERATIONS

          As discussed in Item 3.A.2.VI.b.2, an argument could be made that the
PSCO and Cheyenne gas operations constitute a single integrated utility system
within the meaning of Section 2(a)(29)(B) of the Act.  For purposes of this
Application, however, NCE has elected to treat the gas systems as separate
systems and has analyzed the lost economics associated with divestiture for each
company separately in Exhibit J-1 (Analysis of the Economic Impact of a
Divestiture of the Gas Operations of PSCO and its Cheyenne Subsidiary).  NCE,
accordingly, requests that the Commission authorize retention of PSCO's gas
system and Cheyenne's gas system as separate systems.  NCE's retention of the
gas operations of PSCo and Cheyenne is lawful under Section 8 of the Act and
would not be detrimental to the carrying out of Section 11 of the Act.

                Section 8:  Section 8 of the Act provides that

     [w]henever a State law prohibits, or requires approval or
     authorization of, the ownership or operation by a single company of
     the utility assets of an electric utility company and a gas utility
     company serving substantially the same territory, it shall be unlawful
     for a registered holding company, or any subsidiary company
     thereof . . . (1) to take any step, WITHOUT THE EXPRESS APPROVAL OF
     THE STATE COMMISSION OF SUCH STATE, which results in its having a
     direct or indirect interest in an electric utility company and a gas
     company serving substantially the same territory; or (2) if it already
     has any such interest, to acquire, WITHOUT THE EXPRESS APPROVAL OF THE
     STATE COMMISSION, any direct or indirect interest in an electric
     utility company or gas utility company serving substantially the same
     territory as that served by such companies in which it already has an
     interest.  (Emphasis added).

          On its face, the section indicates that, with the approval of the
relevant state utility commissions, registered holding company systems can
include both electric and gas utility systems.  A careful reading of the section
indicates that the thrust of the section is to preclude the use by registered
holding companies of SEPARATE gas and electric utility companies with
overlapping service territories in order to circumvent any state law
restrictions on the ownership of gas and electric assets by the same company. 
Thus, two types of combination registered holding companies are implicitly
acceptable under the statute absent such state objection -- a registered holding
company system that includes combination companies and a system that includes
separate gas and electric companies.

          NCE believes that a reemphasis by the Commission on Section 8, which
would allow registered combination companies pending state support, is
consistent both with the Act and its policy objectives.  Indeed, over time the
Commission has in fact emphasized different aspects of Section 8 and its
interplay with Section 11 --initially allowing registered holding companies to
own both gas and


                                     -45-
<PAGE>

electric systems under Section 8, then focusing on Section 11 as controlling 
determinations regarding combination companies, and requiring the second 
system to meet a strict interpretation of the requirements set forth in 
clauses A, B and C of Section 11(b)(1).

          In its early decisions, the Commission adhered to the concept that the
decision as to whether or not to allow combination companies is one that states
should make (although the Commission might have to implement it in certain
cases) and, where such systems were permissible, the role of the Commission was
to ensure that both such systems are integrated as defined in the Act.  The
Commission's most notable decision in this line is In the Matter of American
Water Works and Electric Company, Incorporated, 2 SEC 972 (1937).  In this case,
the Commission approved the applicant's voluntary reorganization plan under
Section 11(e) of the Act and permitted the newly reorganized registered holding
company to retain its electric and its gas operations, specifically noting that
while the Act does not contain a definition of single integrated utility in the
context of a combination company:

          We believe, however, that it is proper to regard such a combined
          property as a single integrated system, provided that all of the
          electric properties are integrated and all of the properties, both gas
          and electric, are in fairly close geographic proximity and are so
          related that substantial economies may be effectuated by their
          coordination under common control.  The question of public policy as
          to the common ownership of gas and electric facilities in the same
          territory is apparently left by the statute to the decision of the
          states.(24)

Thus, since the combination company did not violate state policy, there was no
need for the Commission to exercise jurisdiction to implement state policy.

          By the early 1940's, however, the Commission switched its focus to
Section 11 and adopted a narrow interpretation of the standards contained
therein as the controlling factor with regard to combination registered holding
companies.(25)  In connection with its

Electric System, 384 U.S. 176 (1966).  It should be noted that the Commission 
continued to give primacy to state utility commission determinations in 
making decisions regarding combination exempt holding companies.  See, e.g., 
In the Matter of Northern States Power Company, HCAR No. 12655 (Sept. 16, 
1954); Delmarva Power & Light Co., 46 S.E.C. 710 (1976); WPL Holdings, HCAR

analysis of combination companies under Section 11, the Commission frequently 
noted a policy concern existing at that time which advocated separating the 
management of gas and electric utilities based on the belief that the gas 
utility business tended to be overlooked by combination company management 
who focused on the electric utility business. Therefore, gas utilities would 
benefit from having separate management focused entirely on the gas utility 
business.(26) However, both the legislative history of the Act and recent 
changes in the utility industry indicate that it is a propitious time for the 
Commission to reemphasize the provisions of Section 8 of the Act and allow 
combination registered holding companies where, as in this case, they are 
permitted under relevant state law.

          A review of the legislative history of Section 8 clarifies this 
intent.  In its report, the Senate Committee on Interstate Commerce noted 
that the provision in Section 8 concerning combination companies "is 
concerned with competition in the field of distribution of gas and electric 
energy -- a field which is essentially a question of State policy, but which 
becomes a proper subject of Federal action where the extra-State device of a 
holding company is used to circumvent state policy."  The Report of the 
Committee on Interstate Commerce, S. Rep. No. 621 at 31 (1935).  In addition, 
attached to the above-referenced committee report is the Report of the 
National Power Policy Committee on Public-Utility Holding Companies,(27) 
which sets forth a recommended policy that:  "Unless approval of a State 
commission can be obtained the commission should not permit the use of the 
holding-company form to combine a gas and electric utility serving the same 
territory where local law prohibits their combination in a single entity."  
This does not prohibit combination companies where such approvals can be 
obtained.

          Much more recently, in the 1995 Report, the Division noted "it does
not appear that the SEC's precedent concerning additional systems precludes the
SEC from relaxing its interpretation of Section 11(b)(1)(A)" and "that the
utility industry is evolving toward the creation of one-source energy companies
that will provide their

(27) The National Power Policy Committee was an committee appointed by 
President Franklin D. Roosevelt consisting of representatives from various 
government departments concerned with power problems and instructed to report 
to Congress on the coordination of government policy relating to such 
problems.  Its members were Harold L. Ickes, Frank R. McNinch, Elwood Mead, 
T.W. Norcross, Morris L. Cooke, Robert E. Healy, David E. Lilienthal and 
Edward M. Markham.

 customers with whatever type of energy supply they want, whether electricity 
or gas," and recommended that the Commission interpret Section 11(b)(1) of 
the Act to allow registered holding companies to hold both gas and electric 
operations as long as each affected state utility regulatory commission 
approves of the existence of such a company.(28) This change in the industry 
whereby, among other things, customers are increasingly seeking the most 
economic means of meeting their energy needs, and not simply their gas needs 
or their electric needs, is evidenced by the transformation of traditional 
utilities into energy service companies as well as the growth of new energy 
providers such as marketers, the increase in announced mergers between pure 
electric and pure gas utilities, and even the treatment of energy as a 
commodity for arbitrage transactions.  For example, UtiliCorp United and PG&E 
Enterprises have both established energy services subsidiaries to offer, 
among other things, gas and electric power to customers nationwide.(29) 
Similarly, Panhandle Eastern Corp. has changed its name to PanEnergy Corp. to 
"reflect the company's expanding scope of energy services beyond the 
traditional interstate natural gas pipeline business,(30) and Enron Corp. and 
NGC Corp., which have significant gas and power marketing operations, are 
expanding their operations, concluding that "customers in the future will 
want energy services, not a specific fuel."(31) Moreover, registered utility 
holding companies are currently expanding into the energy services business, 
as is evidenced by the fact that Consolidated Natural Gas, Unitil 
Corporation, Eastern Utilities Associates, New England Electric System and 
Northeast Utilities, each a registered holding company, have been authorized 
to offer customers multiple fuel options and related energy services through 
subsidiaries.(32) Finally, the recent announcements of proposed mergers and 
acquisitions that will result in the combination of electric utilities and 
different types of gas companies -- namely, the proposed merger of Brooklyn 
Union Gas Co. and Long Island Lighting Co., the proposed merger between Duke 
Power Company and PanEnergy Corporation, TECO Energy's proposed acquisition 
of Lykes Energy Inc., Enron Corporation's proposed acquisition of Portland 
General Corporation, Texas Utilities Company's proposed acquisition of ENSERCH

Corporation, Houston Industries, Inc.'s proposed acquisition of NorAm Energy, 
Inc., and the proposed merger between Puget Sound Power & Light Co. and 
Washington Natural Gas Co. -- demonstrates that market forces are pushing for 
the convergence of electric and gas operations in one corporate entity; 
namely, a full service utility company.  This trend towards, and the need 
for, convergence of the former separate electric utility function and gas 
utility function into one energy service company was recently recognized by 
the Commission in Consolidated Natural Gas Company, HCAR No. 26512 (April 30, 
1996) where the Commission stated:  "It appears that the restructuring of the 
electric industry now underway will dramatically affect all United States 
energy markets as a result of the growing interdependence of natural gas 
transmission and electric generation, and the interchangeability of different 
forms of energy, particularly gas and electricity."  See also UNITIL Corp. 
Release No. 35-26527 (May 31, 1996) and SEI Holdings, Inc., supra.  Moreover, 
the Commission explicitly recognized that "the utility industry is evolving 
towards a broadly based energy-related business," marked by "the 
interchangeability of different forms of energy, particularly gas and 
electricity."(33)

          Another important factor in favor of focusing on state commission
determinations regarding combination companies is that one of the primary goals
of Congress in enacting the Act was to simplify the corporate structures of
holding company systems to enable states to regulate the production and
distribution of energy.  Section 8 provides that the Act may be used as a tool
to further state policy when state policy prohibits combined electric and gas
operations, and implicitly allows such combination companies where consistent
with state policy.  This is consistent with the general policy of the Act that
local regulators are in the best position to assess the needs of their
communities.  The Act was never intended to supplant local regulation but,
rather, was intended to create conditions under which local regulation was
possible.  Section 21 of the Act, which further codifies this legislative
intent, states:  "Nothing in [the Act] shall affect . . . the jurisdiction of
any other commission, board, agency, or officer of . . . any State, or political
subdivision of any State, over any person, security, or contract, insofar as
such jurisdiction does not conflict with any provision of [the Act] . . . ."

          The legislative history reveals that Section 21 of the Act was further
intended "to insure the autonomy of state commissions [and] nothing in the [Act]
shall exempt any public utility from obedience to the requirements of state
regulatory law."  The Report of the Committee on Interstate Commerce, S. Rep.
No. 621 at 10 (1935).  Thus, the Act should not be used as a tool to override
state policy, particularly when the holding company involved is subject to both
state and federal regulation and when the affected state regulatory commissions
have indicated their support for the combined electric and gas operations in one
holding company system.

<PAGE>

          Finally, this reemphasis on Section 8 fits within the overall 
regulatory scheme of the Act.  First, Section 11 of the Act is flexible and 
was designed to change as the policy concerns over the regulation of utility 
holding companies changed. (34) As discussed below, the utility industry and the
regulation of that industry has changed dramatically in recent years and it 
is competitive forces (the very thing that the Act was designed to promote) 
that are pushing holding companies to offer alternative forms of energy.  
Second, a registered holding company would still be required to demonstrate 
that any acquisition or transaction by which it would become a combination 
company would not be detrimental to the carrying out of the provisions of 
Section 11 of the Act.  However, the construction of those provisions should 
take into account the fundamental policy of the Act and allow local 
regulators to make the major determination with regard to combination 
companies.

          NCE as a combination company is permissible pursuant to the terms of
Section 8 of the Act and is in the public interest.  First, the combination of
electric and gas operations in PSCo and Cheyenne is lawful under all applicable
state laws.  NCE will not be using its holding company structure to circumvent
any state regulations.  In addition, in its order issued approving of the
Transaction, filed herewith as Exhibit D-3.2, the WPSC -- which has, and will
continue to have, direct jurisdiction over the NCE system's gas operations
located in Wyoming -- indicated its support for NCE as a combination electric
and gas utility company through the retention of Cheyenne's gas operations, and
indicated that it would send a letter to the Commission "urging that it not
order the divestiture of Cheyenne Light's natural gas operations."  The WPSC
subsequently sent such letter to the Commission on September 16, 1996, which is
included as Exhibit D-3.3.  In the letter the WPSC stated that the evidence in
the record "establish[es] that the retention by Cheyenne Light of its gas
operations was in the public interest."  The WPSC further stated that it:

          strongly and unambiguously supports the retention of Cheyenne Light's
          gas operations within the NCE holding company system following the
          consummation of the approved merger.  The Wyoming PSC believes that
          such retention is in the interest of consumers and investors in
          Wyoming.  We believe that it is very important to the people of
          Wyoming served by Cheyenne Light that this retention be allowed.

Moreover, the CPUC, in its order approving the Transaction (Exhibit D-2.3,
hereto), "recommend[ed] that the SEC not order divestiture of its gas operations
as a condition of the merger."

                             -50-
<PAGE>

          In addition, the existence of both gas and electric systems in the NCE
holding company system will allow NCE's customers greater choice to meet their
energy needs, especially given the fact that the electric and gas systems
operate in substantially the same territory.  Moreover, the prior fear that a
holding company such as NCE would be able to greatly emphasize one form of
energy over the other based on its own agenda has dissipated both because of the
competitive nature of the energy market, which requires utilities to meet
customer demand for energy above all else, and because state regulators will
have sufficient control over, and would be unlikely to approve, a combination
company that attempts to undertake such practices. 

          Even if the Act were not interpreted as generally permitting
combination gas and electric systems, Section 11 contains additional provisions
that permit the retention by PSCo and Cheyenne of their respective gas systems. 
Section 11(b)(1) of the Act permits a registered holding company to control one
or more additional integrated public utility systems -- i.e., gas as well as
electric --if:

          (A)  each of such additional systems cannot be operated as an
     independent system without the loss of substantial economies which can be
     secured by the retention of control by such holding company of such system;

          (B)  all of such additional systems are located in one state,
     adjoining states, or a contiguous foreign country; and

          (C)  the continued combination of such systems under the control of
     such holding company is not so large (considering the state of the art and
     the area or region affected) as to impair the advantages of localized
     management, efficient operation, or the effectiveness of regulation.

          In the 1995 Report, the Division recommended that the Commission 
"liberalize its interpretation of the "A-B-C" clauses." (35) Historically, as a 
"guide" to determining whether lost economies are "substantial" under Section 
11(b)(1)(A), under its previous narrow interpretation of this section, the 
Commission has given consideration to four ratios, which measure the 
projected loss of economies as a percentage of: (1) total gas operating 
revenues; (2) total gas expense or "operating revenue deductions"; (3) gross 
gas income; and (4) net gas income or net gas utility operating income.  
Although the Commission has declined to draw a bright-line numerical test 
under Section 11(b)(1)(A), under its previous narrow interpretation of this 
Section it indicated that cost increases resulting in a 6.78% loss of 
operating revenues, a 9.72% increase in operating revenue deductions, a 
25.44% loss of gross income, and a 42.46% loss of net income would afford an 
"impressive basis for finding a loss of substantial economies." Engineers

<PAGE>

          Here, the lost economies that would be experienced if the gas
properties of PSCo and Cheyenne were to be operated on a stand-alone basis meet,
and in most instances, exceed these numbers, without any increase in benefits to
consumers.  These lost economies result from the need to replicate services, the
loss of economies of scale, the costs of reorganization, and other factors, and
are described more fully in the Analysis of the Economic Impact of a Divestiture
of the Gas Operations of PSCo and its Cheyenne Subsidiary (the "Divestiture
Study") (Exhibit J-1 hereto).

          As set forth in the Divestiture Study, divestiture of the gas
operations of PSCo and Cheyenne into stand-alone companies would result in lost
economies of $43,605,187 for PSCo and $1,682,723 for Cheyenne.  These lost
economies compare with gas operating revenues of $677,326,418 for PSCo and
$15,630,080 for Cheyenne; gas operating revenue deductions of $607,599,384 for
PSCo and $13,681,672 for Cheyenne; gas gross income of $69,727,034 for PSCo and
$1,948,408 for Cheyenne; and gas net income of $51,266,520 for PSCo and
$1,530,526 for Cheyenne.

          On a percentage basis, the lost economies amount to 6.44% of gas 
operating revenue, 7.18% of gas operating revenue deductions, 62.54% of gross 
gas income, and 85.06% of net gas income for PSCo, as well as 10.77% of gas 
operating revenues, 12.30% of gas operating revenue deductions, 86.36% of 
gross gas income, and 109.94% of net gas income for Cheyenne.  The percent 
losses in net gas income alone that will be suffered by the PSCo and Cheyenne 
gas system if operated on a stand-alone basis exceed the 30% loss in the New 
England Electric System case that the Commission has described as the highest 
loss of net income in any past divestiture order. (36) The percentage loss that 
would be suffered by PSCo in gas operating revenue and gross gas income 
exceeds the percentage loss in the majority of diversification orders issued 
by the Commission in the past.  The percentage loss that would be suffered by 
Cheyenne in gross gas income also exceeds the percentage loss in the majority 
of diversification orders issued by the Commission.  The applicable 
percentages here and in past cases are summarized in Exhibit J-3.

          In order to recover these lost economies the PSCo gas division would
need to increase its revenue from rates by $44,607,669 or 6.62% and the Cheyenne
gas division would need to increase rate revenue by $1,775,439 or 11.38%.  These
increases on rate revenues could have a direct and immediate negative impact on
the rates charged to consumers for gas services.  In addition, the customers of
the PSCo and Cheyenne gas business who are also customers of their respective
electric utility business will experience a doubling of their postage costs to
pay two separate bills.  The total estimated increase in such postage costs is
$3.84 per customer, per year, or $3,580,032 in the aggregate ($3,478,637 for
PSCo's gas customers and $101,395 for Cheyenne's gas customers).

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

(36)  New England Electric System, 41 SEC 888 (1964), aff'd, 384 U.S. 176 (1966)
and 390 U.S. 207 (1968).

                             -52-
<PAGE>

          Moreover, it should be noted that the divestiture of PSCo's and
Cheyenne's gas business will result in increased labor and postage costs to both
companies' electric system.  Specifically, it is estimated that the cost to
PSCo's customers would be approximately $44.9 million, or 3.42% of its electric
revenues, and the cost to Cheyenne's customers would be approximately
$1.0 million, or 2.86% of its electric revenues.

          Finally, divestiture of PSCo's and Cheyenne's gas operations would
cause a significant, although difficult to quantify, amount of damage to NCE's
customers, NCE's regulators and NCE's ability to compete in the marketplace. 
Such non-quantifiable costs to customers involve the additional expenses of
doing business with two utilities instead of one (i.e., additional telephone
calls for service and billing inquiries, and costs of providing access to meters
and other facilities for two utilities) and costs associated with making the
entities supply information to shareholders and publish the reports required by
the 1934 Act.  Similarly, regulatory costs involve additional duties for the
staffs of the CPUC and the WPSC as a result of dealing with an additional
utility.  These additional duties would largely be the result of duplicating
existing functions, such as separate requests for approval of financing and rate
case requests.  NCE's competitive position in the market would also suffer
because as the utility industry moves toward a complete energy services concept,
competitive companies must be able to offer customers a range of options to meet
their energy needs.  Divestiture of gas operations would render NCE unable to
offer its customers a significant and important option, namely gas services, and
could damage NCE's long-term competitive potential.

          (B) and (C) clauses:  The remaining requirements of Section 11(b)(1)
are met because the gas operations of PSCo are located in adjoining states
(Colorado and Wyoming) and because the continued combination of the gas
operations under NCE is not so large (considering the state of the art and the
area or region affected) as to impair the advantages of localized management,
efficient operation, or the effectiveness of regulation.  After the combination,
the gas operations of PSCo and Cheyenne will continue to be the same as it is
today with some 960,000 customers in two states and will, accordingly, remain
the largest gas operation in the region.  However, the gas systems are confined
to a relatively small area; sixty-eight percent of PSCo's gas customers are in
the Denver metropolitan area and all of Cheyenne's gas customers are in or
around Cheyenne, Wyoming.  Moreover, based on data through December 31, 1995,
and giving effect to the Transaction, these gas assets will represent only
approximately 14.4% of the total utility assets of NCE, whereas the electric
assets will represent approximately 85.6%; utility operating revenues for the
gas operations will represent 21.2% of the total NCE utility revenues as
compared with 78.8% for the electric operations; and customers of the gas
operations will constitute 38.8% of all NCE utility customers 

                             -53-
<PAGE>

while electric operations will represent 61.2%. (37) Moreover, as the Commission
has recognized elsewhere, the determinative consideration is not size alone 
or size in an absolute sense, either big or small, but size in relation to 
its effect, if any, on localized management, efficient operation and 
effective regulation.

          From these perspectives, it is clear that the continued combination of
the gas operations under NCE is not too large.  With respect to localized
management, management currently is and will remain geographically close to both
gas operations, thereby preserving the advantages of localized management.  From
the standpoint of regulatory effectiveness, each gas operation is organized in a
separate corporation by regulatory jurisdiction which facilitates state
regulation.  In this connection, the relevant state regulatory authorities have
indicated their support for the retention of the gas system by NCE and thereby
recognized that they can continue to regulate this system effectively.  Finally,
as detailed above, the gas operations of PSCo and Cheyenne enjoy substantial
economies as part of the PSCo system, and will realize additional economies as a
result of the Transaction as part of the NCE System.  Far from impairing the
advantages of efficient operation, the continued combination of the gas
operations under NCE will facilitate and enhance the efficiency of gas
operations.  For further discussion of the requirements of Section 11(b)(1)(C),
see the legal memorandum filed as Exhibit J-2 hereto.

               ii.  OTHER BUSINESSES

          As a result of the Transaction, the non-utility businesses and
interests of PSCo and SPS described in Item 1.B.3. above will become businesses
and interests of NCE.  From PSCo, NCE will hold the following non-utility
subsidiaries indirectly through NC Enterprises:  e prime, Natural Fuels, and
their respective subsidiaries.  NCE will hold the following non-utility
subsidiaries through PSCo:  Green & Clear Lakes, 1480 Welton, PSRI, Fuelco, and
the Ditch Companies, and will hold WGI and PSCCC directly.  In addition, PSCo
expects to continue to operate certain of its non-utility businesses directly. 
Finally, NCE may hold NC International directly; alternatively it may hold NC
International indirectly through NC Enterprises and possibly e prime.

          From SPS, NCE will hold the following non-utility subsidiaries and
investments indirectly through NC Enterprises:  UE, Quixx and their respective
subsidiaries and investments.

          Corporate charts showing the non-utility subsidiaries and investments
of PSCo and SPS are filed as Exhibits E-4 and E-5.  A

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

(37)  The relative sizes of the PSCo and Cheyenne gas operations are shown in 
Appendix A (Comparison of PSCo and Cheyenne Gas to Regional Gas Utilities) to 
Exhibit J-1 (Analysis of the Economic Impact of a Divestiture of the Gas 
Operations of PSCo and Its Cheyenne Subsidiary).

<PAGE>

corporate chart showing the projected arrangement of these subsidiaries and 
investments under NCE is filed as Exhibit E-6.

          Standard for retention:  Section 11(b)(1) permits a registered 
holding company to retain "such other businesses as are reasonably 
incidental, or economically necessary or appropriate, to the operations of 
[an] integrated public utility system."  Under the cases interpreting Section 
11, an interest is retainable if (1) there is an operating or functional 
relationship between the operations of the utility system and the non-utility 
business sought to be retained, and retention is in the public interest, (38) or
if (2) the business evolved out of the system's utility business, the 
investment is not significant in relation to the system's total financial 
resources, and the investment has the potential to produce benefits for 
investors and/or consumers. (39) In addition, the Commission has stated that 
"retainable non-utility interests should occupy a clearly subordinate 
position to the integrated system constituting the primary business of the 
registered holding company." (40) As set forth more fully below, the non-utility
business interests that NCE will hold directly or through PSCo and NC 
Enterprises all meet the Commission's standards for retention.  Indeed, most 
of the non-utility subsidiaries' activities fall within the exemption for 
energy-related activities in new Rule 58.

                    I.   DIRECT SUBSIDIARIES OF NCE

          WGI:  WGI transports gas from the PSCo gas system to Cheyenne.  As
discussed previously, this gas pipeline subsidiary ensures access to natural gas
supplies for the gas utility operations of Cheyenne and, thus, is functionally
related to such utility operations.  The Commission's decisions recognize the
functional relationship of gas pipelines to the gas utility business and the
retainability of gas transmission interests in connection with gas utility
operations.  See, e.g., CNG Transmission Corp., HCAR No. 25239 (Jan. 9, 1991);
Central and South West Corp., HCAR No. 14555 (Dec. 28, 1961).  WGI does provide
gas transportation services for three other area gas utilities.

          PSCCC:  PSCCC engages in financing and factoring of certain of PSCo's
fuel inventories and customer accounts receivable.  The Commission has
authorized the acquisition of interests in similar credit companies by
registered holding companies.  See Central and South West Corporation, HCAR
No. 23767 (July 19, 1985).  After the

consummation of the Transaction, but following an interim period (see note 2, 
supra), PSCCC will become a direct subsidiary of NCE and engage in factoring 
and similar transactions with other companies in the NCE holding company 
system, including SPS, on the same terms as transactions with PSCo.  PSCCC 
may also provide factoring services to unaffiliated utilities, although the 
provision of such services shall not exceed 50% of PSCCC's factoring 
business, unless the Commission otherwise authorizes. PSCCC will limit its 
acquisition of such nonaffiliate utility receivables such that for the 
preceding twelve-month period the amount of acquired nonaffiliate utility 
receivables outstanding as of the end of any calendar month will be less than 
the average amount of receivables from NCE associate companies outstanding as 
of the end of each calendar month during the preceding twelve-month period. 
See Central and South West Corporation, 60 SEC Docket 2658 (Dec. 22, 1995).

          NC International:  As noted elsewhere in this application, NC 
International, which is presently a subsidiary of PSCo, after some interim 
period, but no later than September 30, 1997, will become (i) a direct 
subsidiary of NCE, (ii) a direct subsidiary of NC Enterprises, or (iii) a 
direct subsidiary of e prime which in turn will be a subsidiary of NC 
Enterprises. PSCo established NC International to hold its interest in 
Yorkshire Electricity Group plc.  After the Transaction is consummated, 
Yorkshire Electricity Group plc will be qualified as a FUCO under Section 33 
of the Act.  NC International may seek to acquire interests in or operate 
other FUCOs. (41)

                    II.  SUBSIDIARIES AND INVESTMENTS OF NC ENTERPRISES

          UE:  UE is engaged in a variety of engineering, development, design,
construction, and other related services for non-affiliated customers.  UE will
also provide such services to affiliates.  Clearly, the engineering,
construction and design of utility plants is functionally related to the core
utility operations of NCE.  A utility company must be able to construct or
otherwise acquire additional capacity as needed, and UE has a proven ability to
do so.  While UE's principal expertise grew out of the construction of power-
related projects for SPS and it continues to work on power-related projects, UE
does, from time to time, provide engineering and design services for other types
of industrial plant construction.  UE is not expected to conduct its business
principally with NCE affiliated companies.  For example, for calendar 1996 and
fiscal 1996, revenues derived by UE from sales to associates represented only
33.3% and 30.5%, respectively, of its total revenues.  As a non-regulated
subsidiary in the NCE system, UE will be able to compete in the developing
independent, as well as regulated, power markets due to its ability to

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

(41)  In this connection, prior to or after the Transaction, various interests 
that PSCo presently owns directly or indirectly in EWGs may be transferred to 
NCE, NC Enterprises, or NC International and may be designated as FUCOs.  
Moreover, see note 9, supra.

                             -56-
<PAGE>

accomplish plant construction quickly and at a competitive price.  UE also
currently owns twenty-five electric substation facilities that it leases to
twelve industrial customers of SPS.  Revenues from that activity are
approximately $2.5 million per year.  The substations were purchased over a
period of years from SPS, and the customers utilize the leased substations to
secure power from SPS under a favorable transmission tariff recognized by Texas
regulators.  In order to obtain service under this tariff, the customer must own
or lease its own substation facilities.  The customer elects whether to build
its own facility or lease it from UE or some other provider.  SPS maintains a
metering point upstream from the substation to record sales to the particular
industrial customer.  The delivery and sale of the electric energy to the
industrial customer takes place at transmission level voltage prior to the
energy reaching the UE-owned substation.  UE will attempt to renegotiate the
existing leases to make them into capital leases in conformity with generally
accepted accounting principles.  UE will also endeavor to ensure that all future
leases of substation equipment are such capital leases.  At the end of five
years from the date of the SEC Order, to the extent that there are outstanding
any substation leases that are not such capital leases, NCE commits that those
substations will be sold by UE to SPS at their then net book value, and hereby
requests authority to make such transfers at that time.  If any substations are
transferred to SPS, UE personnel may continue to administer the lease
arrangements for SPS for a fee determined in accordance with Section 13 of the
Act and Rules 87 and 90 thereunder.  Except with respect to services provided to
EWGs and FUCOs, and except as provided below, all of UE's activities, as well as
the activities of all of UE's subsidiaries, are limited to the United States. 
UE will not engage in any activity that would cause it to be a "public utility"
under the Act.

     The Commission has authorized registered holding companies to engage in a
number of similar businesses, including engineering, development, construction,
management, and related services.  See, e.g., Central and South West Corp., HCAR
No. 26280 (Apr. 26, 1995) (authorizing Central and South West Services
engineering and construction department to provide services to third parties);
Entergy Corporation, HCAR No. 26322 (June 30, 1995) (authorizing Entergy
Enterprises, Inc. to provide development, design, engineering, construction,
maintenance, and management services to domestic and foreign power projects);
New England Electric System, HCAR No. 26017 (Apr. 1, 1994) (authorizing New
England Electric Resources, Inc. to provide consulting services, including
engineering, design, and construction, to nonaffiliates for profit); General
Public Utilities Corp., HCAR No. 25108 (June 26, 1990) (authorizing engineering
and management services by Energy Initiatives, Incorporated).  The activities of
UE will be similar to those approved by the Commission and thus, UE is
retainable.  In addition, the activities of UE are primarily within the
definition of energy-related activities under Rule 58 and specifically Rule
58(b)(1)(vii), which exempts acquisitions or transactions of energy-related
businesses from the prior approval requirements of Sections 9(a)(1) and 10.

                             -57-
<PAGE>

          In addition to the provision of such services within the United States
and to FUCOs and foreign and domestic EWGs, NCE requests authorization for UE to
provide directly (or indirectly through newly established subsidiaries or joint
ventures) project development, engineering, design, construction and
construction management, pre-operational start-up, testing and commissioning,
operating, fuel management and procurement, maintenance and power plant
overhaul, management and supervision, technical and training, administrative
support, and other similar kinds of managerial and technical services to foreign
developers, operators and owners of power projects, utility systems and
industrial concerns.  The Commission has authorized the provision of similar
services to similar foreign entities.  See Entergy Corporation, HCAR No. 26322
(authorizing Entergy Enterprises, Inc., to directly or indirectly provide these
services directly or indirectly); The Southern Company, HCAR 26212 (December 30,
1994) (authorizing Southern Electric International, Inc. "to render project
development, engineering, design, construction and construction management,
operating, fuel management, maintenance and power plant overhaul, and other
similar kinds of managerial and technical services to . . . non-affiliated
developers, operators and owners of independent power projects and foreign and
domestic utility systems and industrial concerns").  NCE further requests
authorization for UE to provide such services to foreign power projects that it
may develop on its own or in collaboration with third parties (see Entergy
Corporation, HCAR No. 26322) and authorization for UE to form subsidiaries as
domestic or foreign corporations, partnerships, or other entities to perform
such services.  (Id.)

          UE's subsidiary, Vista Environmental, performs environmental
consulting services previously described.  UE's investment in this business is
related to experience gained in assessment and remediation of environmental
matters for utility facilities.  UE, through Vista Environmental, has applied
the learning from the needs of SPS to site assessment, remediation, and
environmental consulting, primarily for municipalities and oil companies.  UE's
total investment in Vista Environmental is $175,000.  Total revenues annually
for Vista Environmental are $900,000, of which UE's proportionate share is
$675,000.  Accordingly, since the business evolved out of the system's utility
operations, the investment is not significant in relation to the system's total
financial resources, and the investment has the potential to produce benefits
for investors and/or consumers as that expertise can be expanded and applied, if
necessary, to NCE system facilities, retention of Vista Environmental is
appropriate pursuant to Section 11(b)(1).  The Commission has authorized
registered holding companies to acquire interests in environmental services
subsidiaries in the past (see, e.g., Central and South West Corporation, HCAR
No. 26367 (Sept. 1, 1995)) and Vista's environmental services are energy-related
activities under Rule 58(b)(1)(vii).

          UE's wholly owned subsidiary Utility Services performs primarily two
types of services:  Maintenance, repair and installation of cooling towers for
power facilities and other industrial users, and resource recovery which is the
collection, processing, and sale of scrap metals that are a byproduct of SPS's
utility operations.  In 

                             -58-
<PAGE>

connection with the cooling tower work, Utility Services has developed wood 
fabrication capability with respect to cedar components in cooling towers for 
power plants.  That wood fabrication experience has expanded to the 
fabrication of wooden cross arms for utility poles.  The scrap metal services 
business grew out of the SPS utility operations and currently approximately 
99% of the scrap processed comes from SPS.  NCE requests, however, should the 
opportunity arise, approval for Utility Services to utilize excess capacity 
by providing services to non-associate companies.  In no event will Utility 
Services provide scrap metal recovery services to non-associate companies 
such that more than 49% of the revenues derived from this business will be 
from non-associates absent further authority from the Commission.  The 
cooling tower and wood fabrication business also grew out of SPS's utility 
operations and the desire to utilize the expertise developed in those 
operations more fully and thereby defray the costs of the entire operation in 
a way that benefits the entire system.  For the years 1991 through 1995 
approximately 68% of the cooling tower work was performed for associate 
companies.  In 1996, that percentage increased to approximately 95%.  By 
utilizing excess capacity to build cooling towers, that expertise is 
available to associate companies as needed, and the fixed costs can be spread 
over a wider customer base.  With respect to the wood fabrication portion of 
that business, again the primary use with respect to wood for cooling towers 
is for associate companies, and the ability to utilize the excess capacity 
benefits the entire system.  The sole customer for the utility pole crossarm 
operations is SPS, although NCE requests, should the opportunity arise, 
approval for Utility Services to engage in that business for non-associate 
companies.  In no event shall the cooling tower or wood fabrication services 
provided to non-associates exceed 49% of annual revenues of Utility Services 
from those businesses absent further authority from the Commission.  These 
primary businesses are retainable for the same reasons cited above with 
respect to UE.  Both the cooling tower services and the resource recovery 
activities grew out of the utility operations of SPS and retention will 
benefit the NCE system.  These activities are energy related under Rule 
58(b)(1)(vii).  Except with respect to services that may in the future be 
provided to EWGs or FUCOs, all of the services to be provided by Utility 
Services will be provided in the United States.  Utility Services does not, 
and will not in the future, engage in any activity that would cause it to be 
a "public utility" under the Act.

          UE's wholly-owned subsidiary, PRC, is in the business of providing
human resource services from a database of names of unaffiliated technical
personnel who are available to provide temporary technical services to various
projects.  PRC matches its customers with the desired non-affiliated technical
personnel for a fee.  PRC's customers include associate companies (approximately
59% at SPS or PSCo; 80% if all associate companies are included) and other
unrelated industrial companies.  Selling these services to non-associates helps
ensure that the services are available to associate companies by allowing PRC to
utilize more fully its capacity and to spread the costs associated with the
services over a wider customer base.  Approximately 97.5% of PRC's placements
are with affiliates and 

                             -59-
<PAGE>

companies that will be associate companies after the merger.  Total revenues 
for the seven months ended March 31, 1997 were $600,710, 94% of which is 
attributable to placements with affiliates and companies that will be 
associate companies after the merger.  In no event shall the services 
provided to non-associates exceed 49% of the annual revenues of PRC unless 
further authorized by the Commission.  Only a minimal additional investment 
was required to create such a database, and UE's investment in this company 
is immaterial.  Furthermore, the development of this database is incidental 
to and in connection with the services and expertise UE already provides to 
third parties and to affiliates.  The Commission has permitted affiliates of 
other registered holding companies to operate and market similar database 
services. See, e.g., EUA Energy Investment Corporation, HCAR No. 25976 
(January 24, 1994); Central and South West Services, Inc., HCAR No. 25132 
(August 10, 1990).  Thus, the retention of this subsidiary, subject to the 
50% test outlined above, should be permitted.  Since this database had its 
origins in the experience gathered in utility operations of SPS and provides 
a benefit to the system, this activity is also covered directly by Rule 
58(b)(1)(vii).

          Quixx:  The primary business of Quixx is investment in QFs, EWGs,
foreign utility companies ("FUCOs") and other energy-related projects.  In
connection therewith, Quixx may conduct preliminary development activities
including project due diligence and design; design review; market studies; site
inspection; preparation of bid proposals (including the posting of bid bonds,
cash deposits or similar instruments); application or required permits or
authorizations, acquisition of options on sites and other rights; negotiation
and execution of contractual commitments with owners of existing facilities,
equipment vendors and other project contractors; negotiating of financing
commitments with lenders and co-investors; and other activities required in
preparation for the acquisition or financing of one of the listed entities. 
Section 32 of the Act exempts EWGs from the provisions of the Act while
Section 33 of the Act exempts FUCOs from the provisions of the Act, thereby
allowing registered holding companies to obtain interests in such entities. 
Moreover, the Commission has authorized the formation and financing of a number
of non-utility subsidiaries of registered holding companies in order to invest
in and hold securities of QFs, FUCOs, and EWGs.  See, e.g., The Southern
Company, HCAR No. 26212 (Dec. 30,1994); Entergy Corp., HCAR No. 26322 (June 30,
1995); Northeast Utilities, HCAR No. 25977 (Jan. 24, 1994) (authorizing Charter
Oak Energy and COE Development Corporation); Central and South West Corp., HCAR
No. 26156 (Nov. 3, 1994) (authorizing CSW to form, acquire, finance and own
securities of FUCOs); Central and South West Corporation, HCAR No. 26155
(Nov. 2, 1994) (authorizing investment in a joint venture which will construct,
own and operate QFs and EWGs).  In addition, Rule 58 lists the ownership of QFs
as an energy-related activity under Rule 58(b)(1)(viii).  Thus, Quixx's
principal operations are retainable under the Act.  NCE seeks an order only with
respect to the existing investments of Quixx.  Quixx will not acquire interests
in projects unless the acquisition is either approved by the Commission under
the Act, or is exempt from the requirement of prior Commission approval.

                                  -60-

     The following are (or, when constructed, will be) QFs or holding 
companies for such entities and are thus retainable under Section 11 as 
demonstrated by the Commission's precedent and Rule 58:  BCH, Quixx Carolina, 
Inc., Quixx WPP94, Inc., Carolina Energy Limited Partnership, Windpower 
Partners 1994, L.P., Quixx Linden, L.P., Quixlin Corp., Borger Energy 
Associates, L.P., and Quixx Borger Cogen, Inc.  The following are (or, when 
construed, will be) EWGs or holding companies for such entities and are also 
retainable under Section 11 as demonstrated by the Commission precedent:  
Quixx Jamaica, Inc., Quixx Jamaica Power, Inc., KES Montego, Inc., KES 
Jamaica, L.P.(42), the Mosbacher Companies (which may also invest in FUCOs), 
Quixx Mustang Station, Inc. and Denver City Energy Associates, L.P.

          Quixx's subsidiary company Vedco Louisville, L.L.C. operates a
facility that generates steam for use at a nearby DuPont manufacturing facility.
The Commission has previously approved the retention or acquisition of similar
businesses.  See Cinergy Corp., HCAR No. 8767 (February 20, 1996); The Southern
Company, HCAR No. 26468 (February 2, 1996) (acquisition of energy-related
companies that derive substantially all of their revenue from the production,
conversion, or distribution of steam); Mississippi Power Co., HCAR No. 16791
(July 28, 1970); General Public Utilities Corp., 32 SEC 807, 840-41 (1951)
(retention of steam heating systems in which steam was used to both generate
electricity and was sold to customers for steam heating purposes).  Such a
business is reasonably incidental to the operation of an electric utility system
and is therefore retainable.  The production, conversion, and distribution of
thermal energy products, including process steam, is also permitted by Rule
58(b)(1)(vi).

          In addition to its primary business, Quixx through Quixx Resources and
Quixx WRR, L.P. holds interests in certain water rights in Texas.  These water
rights are integrally related to the utility business of SPS in that water is a
scarce commodity in Texas, without which utility generation plants cannot be
constructed or operated.  The water rights were originally acquired in
connection with the expected construction of a power generation station that was
not ultimately built.  They are currently being held for future use in
connection with the anticipated need for additional generation 


- ------------------
(42) KES Jamaica, L.P., is an EWG which is owned by KES Montego, Inc. and 
Quixx Jamaica, Inc.  Quixx Jamaica Power, Inc. has an agreement in principle 
to acquire 100% of the stock of KES Montego, Inc.  All of these entities 
qualify as EWGs in that their sole business is the ownership or operation of 
an EWG.  Official EWG status has only been sought and obtained with respect 
to KES Jamaica, L.P., the actual generation entity, but could be obtained 
with respect to all of these entities if required but actual designation 
should not be required since each entity is exclusively in the business of 
owning and holding the interest and securities of an exempt entity.  See 
General Public Utilities, HCAR No. 26457 (January 19, 1996); New England 
Electric System, HCAR No. 26504 (April 15, 1996); Northeast Utilities, HCAR 
No. 26623 (Dec. 12, 1996).

capacity in Texas.  See In Re Cites Service Power and Light Company, HCAR No. 
4489 (Aug. 18, 1943).  Quixx also provides, and seeks authorization to 
continue to provide, financing for heat pump acquisitions by SPS customers.  
Quixx had loans totaling $8.7 million as of February, 1997.  It expects to 
finance up to $5 million in each of 1997, 1998, and 1999.  The loans are 
generally of a 60-month duration with a 13% fixed annual simple interest 
rate.  This activity is functionally related to the utility business, was 
developed in the course of SPS's utility business, and is de minimis in 
amount, contributing $1.2 million in income representing interest on heat 
pump financing contracts for the twelve months ended August 31, 1996.  Rule 
48 of the Act contains exemptions from the financing approval requirements 
for certain system companies to finance the acquisition of utility appliances 
such as water pumps for the customers of the operating utility companies 
within the holding company system.  Although not directly applicable to 
Quixx, this rule does indicate that such activity is permissible for a 
registered holding company system and is functionally related to utility 
operations.  Finally, the Commission has authorized financing and leasing of 
utility equipment for customers.  See Central and South West Corporation, 
HCAR No. 26367 (Sept. 1, 1995); Entergy Corporation , HCAR No. 25718 (Dec. 
28, 1992).  See also, Consolidated Natural Gas Co., HCAR No. 26234 (Feb. 23, 
1995) (authorizing CNG's subsidiary, CNGF, to finance the purchase of certain 
gas equipment, including "New Technology Equipment" and "Alternate Fuel 
Equipment," by customers who would, in turn, purchase gas from CNG System 
subsidiaries).

          Amarillo Railcar Services, a division of Quixx is also retainable. 
The Commission has authorized electric utility subsidiaries of registered
holding companies to construct, finance, acquire, and operate unit train repair
and maintenance facilities generally where the railcars were used to service the
utility by transporting coal.  In the Matter of Southwestern Electric Power
Company (subsidiary of CSW), HCAR Nos. 19643; 19468 (Aug. 9, 1976; April 6,
1976, respectively); In the Matter of Ohio Power Company (subsidiary of American
Electric Power Company), HCAR Nos. 22977; 21886; 21173 (June 17, 1983; Jan. 16,
1981; Aug. 3, 1979, respectively).  The operations of Amarillo Railcar are
incidental to, and were developed as a result of, utility operations and
expertise in connection with the transportation of coal and thus appear to be
encompassed within Rule 58(b)(1)(ix).  Although a majority of Amarillo Railcar
Services' work involves railcars that transport coal for use by NCE system
utility companies, it is also a general railcar maintenance operation that
provides services to unaffiliated third parties.  Amarillo Railcar's net
revenues in the calendar year ended December 31, 1996 and the fiscal year ended
August 31, 1996 were $1,226,000 and $1,288,000, which accounted for only one-
tenth of one percent (both years) of SPS's overall revenues.  It is a small
operation that developed from utility operations, incurs very little cost at
this point, and is beneficial to shareholders, and thus is retainable.

          Quixx also holds a royalty interest in coal and other minerals
produced from certain properties owned by the Pittsburgh and 

                                -62-

<PAGE>

Midway Coal Mining Company.  The Commission has approved of the acquisition 
of coal and mineral rights by registered holding companies or their utility 
subsidiaries, see, e.g., In the Matter of Indiana and Michigan Electric 
Company (subsidiary of American Electric Power Company), HCAR No. 19064 (June 
26, 1975), as well as the transfer of such rights between subsidiaries, see, 
e.g., The Columbia Gas System, Inc. et al., HCAR No. 24881 (May 5, 1989); 
National Fuel Gas Supply Corporation, et al., HCAR No. 24491 (November 4, 
1987).  Therefore the Commission should not object to the retention of 
royalty interests in the coal and mineral production of the Pittsburgh and 
Midway Coal Mining Co.  These rights were acquired in settlement of 
litigation over an acquisition and are de minimis, contributing $316,000 and 
$489,000 in revenues from royalty payments on coal for the twelve months 
ended December 31, 1996 and December 31, 1995, respectively.

          Quixx Power Services, Inc., a wholly-owned subsidiary of Quixx
("QPS"), will operate and maintain generation facilities in various locations,
which will include cogeneration facilities in which Quixx holds an equity
interest.  QPS has a contract to operate and maintain the BCH and the Carolina
Energy facilities.(43)  QPS will operate the Linden facility, once constructed
and operational, and the KES Jamaica facility.  QPS will perform similar
operation and maintenance services for unaffiliated projects.  All of the
facilities that QPS provides operations and maintenance services for are QFs,
EWGs or FUCOs.  Except with respect to possible future work for EWGs and FUCOs,
QPS's activities are limited to the United States.  QPS will not engage in any
activity that would cause it to be a "public utility" under the Act.  The
expertise needed to provide such services is listed as an "energy-related"
activity in Rule 58(b)(1)(vii).  The services to be provided are consistent with
the type of activities approved in various "consulting services" cases such as
The Southern Company HCAR No. 26132 (July 17, 1981) and American Electric Power
Company, HCAR 22468 (April 21, 1982) (each authorizing the creation of a
consulting subsidiary to render management, technical and training services to
non-affiliated entities).  In addition, QPS' activities are de minimis,
accounting for revenues of $712,000 and $609,000 for the twelve months ended
December 31, 1996 and December 31, 1995, respectively.

          e prime:  e prime is an energy services company that intends to engage
in a broad array of energy-related activities and consumer services.  e prime
also has investments in a QF and an EWG, and intends to acquire interests in
other QFs, EWGs, and FUCOs.  Because e prime is a start-up company formed in
1995, its activities are in 


- ---------------------
(43) Because the BCH facility is not currently being operated and the 
maintenance and operations agreement between that project and QPS have been 
abrogated, there is no longer a relationship with an associate company at 
that project.  The Carolina Energy project is on hold, but even if 
construction is completed, the owners have determined to replace QPS as the 
operations and maintenance provider with an affiliate of one of the other 
owners.

                                    -63-

their preliminary phases.  It is anticipated that e prime will further 
develop some or all of these activities.  The energy-related activities e 
prime is developing and engaging in, or intends to develop and engage in, 
include:  electric and gas brokering and marketing at both the wholesale and, 
where authorized by state law, retail levels; energy consulting and project 
development services; construction, operation and ownership of electric 
generation and gas storage facilities; and construction, operation and 
ownership of equipment and facilities to gather and disseminate 
energy-related management information.  Other consumer service activities e 
prime is, or intends to, engage in include information processing, 
telecommunications, and other technology-based services.  e prime, however, 
does not own any facilities or engage in any activities that cause it to be, 
nor will it acquire an interest in any facilities or engage in any activities 
that will cause it to be, a public utility within the meaning of Section 
2(a)(5) of the Act unless authorized by the Commission

          At present e prime is considering how to structure its business in
light of regulatory requirements and other legal considerations, and is giving
particular consideration to developing these activities through special-purpose
subsidiaries on a line of business basis.  Indeed, substantially all of the
activities of e prime directly, or indirectly through subsidiary companies, will
be energy-related activities under Rule 58 or ETC, EWG, or FUCO activities under
Sections 32, 33, or 34 of the Act.  With the exception of its interest in Young
Gas, and possibly e prime Networks (which may or may not be constituted as an
ETC or qualify as an energy-related company under Rule 58), all of e prime's
activities and investments are expected to be exempt under the Act in accordance
with those sections or rules.  Thus, all of its ownership interests in electric
facilities are likely to be limited to exempt entities.  e prime will not engage
in, nor acquire an interest in, any other businesses which are not exempt unless
approved by further order of the Commission.

          The following is a fuller description of e prime's current activities
and the bases on which they may be retained:

               Marketing:  e prime is currently engaged in purchasing gas and
electricity from, and reselling it to, utility and non-utility companies at
negotiated rates reflecting market conditions.  As part of its marketing
activities, e prime intends to employ risk management strategies -- e.g., swaps,
options, and futures contracts -- to enable buyers to hedge against adverse
price changes.  Consistent with the requirements of HCAR No. 26667 (at 33),
wherein the Commission adopted Rule 58, e prime will only use hedging tools to
minimize risks associated with contracts for purchase or sale of energy
commodities; it will not use such tools to engage in speculation.  e prime has
received approvals and waivers from the FERC to Act as an electric power
marketer.  Unless authorized by the FERC, the marketing or brokering of power by
e prime will not involve purchases from and sales to associate companies in the
NCE system.  Both power and gas marketing services will be offered to third
parties. Consistent with 

                                  -64-

<PAGE>

prior Commission orders -- e.g., Southern Company Services, Inc., HCAR No. 
26602 (November 28, 1996) -- e prime will not without separate authorization 
from the Commission, engage in marketing and brokering activities outside of 
the United States.  e prime is currently engaging in electric and gas 
marketing directly.(44)  However, e prime is presently evaluating whether to 
transfer these activities to a special purpose subsidiary, e prime Marketing. 
Such transfer will require FERC authorization.

               The present and planned marketing activities of e prime are
similar to those the Commission has previously authorized and, therefore, may be
retained consistent with the requirements of the Act.  For example, in SEI
Holdings, Inc., HCAR No. 26581 (September 26, 1996), the Commission found it
appropriate under the Act for a subsidiary of a registered holding company to
engage in both retail and wholesale gas and electric marketing activities.  See
also Eastern Utilities Associates, HCAR No. 26493 (March 14, 1996), New England
Electric System, HCAR No. 26520 (May 23, 1996); Unitil Corporation, HCAR
No. 26127 (May 30, 1996); New England Electric System, HCAR No. 26520 (May 23,
1996); Northeast Utilities, HCAR No. 26544 (Aug. 13, 1996).  Moreover, this
Commission has recently found risk management activities to be permissible under
the Act.  American Electric Power Company, Inc., Release No. 26572
(September 13, 1996); The Columbia Gas System, Inc., Release No. 26610
(November 21, 1996).  Moreover, "[t]he brokering and marketing of energy
commodities, including but not limited to electricity, natural or manufactured
gas and other combustible fuels," are activities that an energy-related company
may engage in under Rule 58(b)(1)(v).  Thus, if e prime transfers the marketing
activities it is presently directly engaging in to e prime Marketing, that
entity will qualify as an energy-related company under Rule 58.

               Consulting Services:  e prime also provides demand side
management services and intends to provide other consulting services to
commercial and industrial customers.  These services include or are expected to
include energy analysis, project management, design and construction, energy
efficient equipment installation and maintenance, facilities management
services, environmental services and compliance, fuel procurement, and other
similar kinds of managerial and technical services.  The expertise needed to
provide such services is listed as "energy-related" activities in
Rule 58(b)(1)(i) and (vii).  As discussed in detail with regard to the retention
of UE, the Commission has authorized registered holding company subsidiaries to
engage in utility-related consulting services numerous times in the past.  See
also, Central and South West Corporation, HCAR No. 26367 (Sept. 1, 1995) and
American Electric Power Company, HCAR No. 26267 (April 5, 1995) (both cases
authorizing the provision of a variety of demand-side management and other
energy management services).


- -----------------------
(44) e prime is also engaging in marketing activities indirectly through Texas 
Ohio Gas, which is discussed below.

                                  -65-

<PAGE>

               Development, ownership and operation of QFs, EWGs, and FUCOs: 
e prime is constructing or owns and operates electric generation, transmission,
and distribution and gas storage facilities, directly or indirectly, and is
continuing to evaluate additional projects.  The categories of electric
facilities in which e prime has or may have an interest are QFs, EWGs, and
FUCOs.  In connection therewith, e prime may conduct preliminary development
activities including project due diligence and design; design review; market
studies; site inspection; preparation of bid proposals (including the posting of
bid bonds, cash deposits or similar instruments); application or required
permits or authorizations, acquisition of options on sites and other rights;
negotiation and execution of contractual commitments with owners of existing
facilities, equipment vendors and other project contractors; negotiating of
financing commitments with lenders and co-investors; and other activities
required in preparation for the acquisition or financing of one of the listed
entities.(45)

          The Commission previously has authorized such activities by companies
in a registered holding company system.  See The Southern Company, HCAR
No. 26212 (Dec. 30, 1994).  Managerial and technical services provided to such
entities by e prime may include project development, engineering, design,
construction and construction management, operating fuel management, testing,
maintenance and administrative and technical support, all of which, again, have
been previously authorized.  See American Electric Power Company, HCAR No. 26267
(April 5, 1995); Entergy Corporation HCAR No. 26322 (June 30, 1995).  Moreover,
with respect to e prime's ownership of QFs, Rule 58(b)(1)(viii) identifies
"[t]he development, ownership or operation of 'qualifying facilities,' as
defined under the Public Utility Regulatory Policies Act of 1978, as amended
('PURPA'), and any integrated thermal, steam host, or other necessary facility
constructed, developed, or acquired primarily to enable the qualifying facility
to satisfy the useful thermal output requirements under PURPA," as an energy-
related activity.

          e prime presently has interests in one QF and one EWG.  e prime 
owns a 50% interest in Johnstown Cogeneration, which owns a 3 MW QF located 
in Johnstown, Colorado.(46)  e prime international has a 25% interest in Kazak 
Power Partners Limited, which owns Karaganda II, an EWG located in Topar, 
Kazakstan.  e prime international also wholly owns e prime operating, which 
has entered into a contract to operate Karaganda II, and intends to enter 
into other EWG operating arrangements.  e prime international, e prime 
operating, and Kazak 


- -------------------------
(45)  Certain of these business opportunities are being developed by ep3, L.P., 
a subsidiary of e prime which is discussed below.  It is expected that the 
entities owning such facilities will qualify as either EWGs or FUCOs.

(46)  The output of this facility is sold to PSCo at an avoided cost rate 
established by the CPUC in accordance with PURPA and the FERC's and CPUC's 
regulations implementing PURPA.

                              -66-

<PAGE>

Power Partners Limited have each separately filed with the FERC an 
application for determination of EWG status on February 28, 1997.  The FERC 
issued letter orders granting the requested EWG status for each of the three 
entities on April 10, 1997.  e prime also established e prime (Belize) 
Limited to develop, own, and operate an eligible facility in Belize.  
However, it does not appear that e prime will pursue that project, and e 
prime (Belize) Limited will probably be dissolved.(47)

          After the consummation of the Transaction, NC International may become
a wholly-owned subsidiary of e prime.  Alternatively, NC International will
become a direct subsidiary of NC Enterprises or NCE.  The activities of NC
International have previously been discussed in Item 3.A.2.a.ii.I. (Direct
Subsidiaries of NCE).

               Telecommunications, Information, and Other Technology Based
Services:  A potential business expansion by e prime, either directly or
indirectly through one or more subsidiaries, is the provision of
telecommunications, information, and other technology based services to third-
parties and possibly affiliates as well.

          In this connection, e prime has established two subsidiaries, e prime
Telecom and e prime Networks. e prime Telecom intends to provide long-haul fiber
capacity using excess capacity on PSCO's fiber system on a wholesale basis to
non-associate companies and engage in other ETC activities.  An application for
determination of e prime Telecom's ETC status was filed on March 10, 1997 with
the FCC.  Any transfer of assets by PSCo necessary for e prime Telecom to engage
in that business will be done in a manner so as to satisfy the state commission
approval requirements of Section 34(b) of the Act and the Colorado Public
Utilities Law.

               e prime Networks was established by e prime to develop and
operate a fixed remote meter reading network to provide meter reading services
to PSCo for electric and gas operations in the Denver metropolitan area. 
e prime Networks may also provide such services to other electric and gas
utilities, and perhaps to water utilities as well.  This network will consist of
meter reading devices attached to the utility poles of PSCo, and perhaps other
utilities, that will be able to read adapted meters in surrounding sectors.  The
Commission has authorized utilities to provide meter reading services to third-
parties in the past, e.g., Central and South West Corporation, HCAR No. 26250
(March 14, 1995); Jersey Central Power & Light Co., HCAR No. 26600 (November 5,
1996); Appalachian Power Company, HCAR No. 26639 (January 2, 1997).  e prime
Networks is considering applying for a determination of ETC status. 
Alternatively, the provision of meter reading services may be deemed an energy-
related activity under Rule 58(b)(1)(vii).


- ----------------------
(47) As discussed in Item 3.A.2.a.ii.I.(Direct Subsidiaries of NCE), NCE may 
realign e prime's present foreign EWG investments so that they are held by 
NCE, NC Enterprises, or NC International after the Transaction.  Moreover, 
these EWGs may be designated as FUCOs.

                              -67-

<PAGE>

          In addition to the above activities, e prime (1) expects to provide
energy management services and sell devices, including computer software and
hardware used for energy management purposes; and (2) may develop or market
other electrotechnologies.  e prime expects that these activities would fall
within the scope of Rule 58(b)(1)(i) and (ii).

          In the event that e prime in the course of providing these -- or any
other -- products or services uses intellectual property developed by NC
Services, or the NCE system operating companies for utility operations, e prime,
consistent with the formula that the Commission approved in Northeast Utilities,
HCAR No. 25900 (September 30, 1993), will pay NC Services, or the NCE company
that developed the intellectual property for utility purposes, that e prime uses
or licenses:  (1) 70% of the revenues from the intellectual property until the
company that developed the intellectual property recovers its programming and
development costs; and (2) 20% of such revenues thereafter.  e prime will pay
cost for intellectual property that an NC Services or an NCE system operating
company develops at its request.

               Financing:  On one past occasion, e prime has engaged in customer
financing.  In this instance, e prime purchased and now leases to a customer a
gas-fired air compressor used for making snow.  The customer's use of the air
compressor is in conjunction with one of PSCo's CPUC approved DSM programs.  The
customer will obtain ownership of the air compressor at the end of the lease. 
The outstanding balance of the lease is $324,367.  e prime may in the future
wish to engage in other customer financing activities in connection with
services and products that it provides.  However, it will not do so unless it
first obtains authorization from the Commission in a separate application or is
otherwise allowed by Commission rule to do so.

               Young Gas:  As of February 1, 1996 as the result of a
contribution of Young Gas' shares from PSCo, e prime holds all of the
outstanding shares of Young Gas, a limited liability company.  Young Gas owns
47.5% interest in a limited partnership that owns a gas storage facility that
stores gas underground primarily for use in PSCo's gas operations.  The rates
charged to PSCo for such services by the partnership are determined in
accordance with FERC regulations and are cost-based.  The partnership provides
services to third parties at FERC determined rates as well.  The Commission has
recognized the functional relationship of gas storage facilities to a holding
company system's gas utility business.  In National Fuel Gas Company, HCAR
No. 25437 (Dec. 20, 1991), the Commission authorized the registered holding
company:  (1) to acquire a wholly-owned subsidiary to market natural gas and to
assist in transporting and storing natural gas, and (2) to acquire a 50%
interest in a partnership engaged in purchasing, storing, transporting, and
marketing natural gas throughout the United States.  See also, Consolidated
Natural Gas Co., HCAR No. 26234 (Feb. 23, 1995) (describing CNG System as
comprised of, inter alia, CNG Energy Services Corporation, which gas marketing
subsidiary "sells gas and related services such as storage . . . to System
[companies] 

                                -68-

<PAGE>

and nonassociates . . .").  Thus, because PSCo is both a gas and an
electric utility, the Commission should find Young Gas to be functionally
related to its utility business.

               Texas Ohio Gas and Texas Ohio Pipeline:  As of September 4, 1996,
e prime has held all of the outstanding shares of Texas Ohio Gas, a natural gas
marketer at both the retail and wholesale levels.  Texas Ohio Gas is also
engaged in an electric retail pilot program in New York.  Prior to the
consummation of the Transaction, Texas Ohio Gas expects to seek authorization
from the FERC to market electric power and energy at the wholesale level.  As is
the case with e prime's marketing activities, Texas Ohio Gas will not engage in
marketing and brokering activities outside of the United States unless
authorized by the Commission.  As discussed with regard to the retention of e
prime, gas and electric marketing activities, including the use of risk
management strategies, are consistent with Commission precedent, and are listed
as an energy-related activity under Rule 58(b)(1)(v).

          In connection with its purchase of all outstanding shares of Texas
Ohio Gas, e prime also purchased 100% of the shares of Texas Ohio Pipeline,
which owns a 900 foot FERC regulated interstate gas pipeline linking the
pipelines of Texas Eastern Transmission Corporation and Tennessee Gas Pipeline
Company.  This pipeline provides operational flexibility, allowing gas to be
moved from one pipeline to another, that can be used to assist in Texas Ohio
Gas's marketing activities. To elaborate briefly, Texas Ohio Gas, which
presently has the right to use 100% of the capacity of the pipeline owned by
Texas Ohio Pipeline, has various firm market obligations.  Because there is an
occasional lack of capacity on the two pipelines that Texas Ohio Pipeline's
pipeline inter-connects, Texas Ohio Gas is able to use Texas Ohio Pipeline to
move gas from one pipeline to another to meet those obligations.  The pipeline
will also allow Texas Ohio Gas and other gas transportation customers to respond
to certain market events, which will further assist Texas Ohio Gas's gas
marketing activities.  e prime paid $2,000,000 for Texas Ohio Pipeline.  As a
consequence, retention of Texas Ohio Pipeline should be allowed.  See SEI
Holdings, Inc., HCAR No. 26581 (September 26, 1996) (authorizing the acquisition
or construction of physical assets that are reasonably necessary in the day-to-
day conduct of marketing operations).

               ep3:  e prime has a 50% partnership interest (20% general
partnership interest, 30% limited partnership interest) in ep3, which was formed
to engage, or invest, in the business of marketing, developing, financing,
constructing, managing, and operating electrical energy transmission,
distribution, or generation facilities -- all of which are expected to qualify
as FUCOs or EWGs -- or providing consulting services related thereto.  It is
expected that the primary focus of these activities will be on Latin America and
other emerging foreign markets; no domestic activities are presently
contemplated.  The Commission has found these activities to be permissible under
the Act.  See, e.g., Northeast Utilities, HCAR No. 25977 (Jan. 24, 1996)
(authorizing Charter Oak Energy and COE 

                              -69-
<PAGE>

Development Corporation); Central and South West Corp., HCAR No. 26156 (Nov. 
3, 1994) (authorizing CSW to form, acquire, finance, and own securities of 
FUCOs); Central and South West Corporation, HCAR No. 26155 (Nov. 2, 1994) 
(investment in a joint venture which will construct, own, and operate QFs and 
EWGs).(48)

          Natural Fuels:  This 83.63% owned subsidiary engages in the 
commercialization of compressed natural gas as a motor fuel.  Services which 
Natural Fuels offers to third parties include conversion of vehicles to 
operate on natural gas or propane; construction, ownership, and operation of 
compressed natural gas fueling facilities; and the assembly and sale of 
compressed natural gas fueling facility equipment.

          The Commission previously has authorized other registered holding 
companies that own gas utility operating companies to form subsidiaries to 
engage in the activities that are carried out by Natural Fuels.  In 
Consolidated Natural Gas Co., HCAR No. 25615, (Aug. 27, 1992), Consolidated 
Natural Gas Company and its wholly-owned subsidiary, CNG Energy Co., sought 
authorization for CNG Energy's Natural Gas Vehicle Division to engage in, 
inter alia, the following activities:  (1) buying and reselling equipment 
necessary to transform vehicles from gasoline to natural gas and/or combined 
natural gas and gasoline operation ("Conversion Equipment"); (2) installing 
and/or maintaining Conversion Equipment on customer vehicles and providing 
training on the use, installation and maintenance thereof; (3) designing, 
constructing, owning, leasing, selling and/or maintaining refueling stations 
or mobile refueling operations for the refueling of natural gas vehicles; and 
(4) entering into various joint arrangements with unrelated companies or 
individuals to engage in these activities.  The retention of Natural Fuels 
should thus be authorized.  See also, Consolidated Natural Gas Co., HCAR No. 
26234 (Feb. 23, 1995) (authorizing CNG's subsidiary, CNGF, to finance the 
purchase of certain gas equipment, including "New Technology Equipment" and 
"Alternate Fuel Equipment," by customers who would, in turn, purchase gas 
from CNG System subsidiaries).

          NCE is aware that in Rule 58(b)(1), the Commission specified that 
companies engaged in the ownership, operation, sale of compressed natural gas 
powered vehicles, and the installation and servicing of refueling equipment 
for such vehicles, could only be deemed to be an "energy-related company" 
within the meaning of Rule 58 if the securities of such company "are 
acquired, directly or indirectly, by a registered holding company whose 
public-utility company subsidiaries are primarily gas utility companies."  
Thus, Natural Fuels cannot be deemed an energy-related company within the 
meaning of Rule 58 since the NCE utility operating companies are primarily 
electric utilities.  

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

(48)  In connection with PSCo's acquisition of IPC (see note 9, supra), a new 
corporation, yet to be named, may be formed.  Its activities will be the same 
as those currently performed by ep3, and the activities of ep3 may be wound 
down. It will initially be held by IPC and by either NC Enterprises, NC 
International, or e prime.


                                     -70-

<PAGE>

However, because PSCo and Cheyenne are combination gas and electric 
utilities, the Commission should find that the activities of Natural Fuels 
are functionally related to their core utility operations and allow them to 
be retained on that basis. Natural Fuels' activities will draw on the 
experience that PSCo and Cheyenne have developed from their gas utility 
operations.  For example, the Compressed Natural Gas Fuel ("CNG") sales 
business requires the compression, drying, and safe handling of high pressure 
natural gas.  The compression expertise in the gas utility carries over to 
the safe design and operation of the compression equipment used in the CNG 
business.  The utility experience in delivering natural gas to utility 
customers carries over to serving the fleet customer with natural gas.  Leak 
detection and repair in both businesses is similar in expertise and safety 
training.  The drying of natural gas in the CNG business is similar to the 
utility expertise of dehydration.  The overall expertise to design, build, 
maintain, and operate a CNG fueling facility is very close to the same 
expertise to design, build, operate, and maintain a gas compression plant and 
pipeline in the gas utility business.

          Moreover, Natural Fuels' business will also expand the market for 
natural gas, which will benefit PSCo's and Cheyenne's gas businesses.

          NC International:  As noted previously, NC Enterprises may directly 
hold PSCO's present interest in NC International after the closing of the 
Transaction.  Alternatively, NCE may hold this interest directly, or NC 
Enterprises may hold this interest indirectly through e prime.  NC 
International's activities have previously been discussed in Item 
3.A.2.a.ii.I. (Direct Subsidiaries of NCE).

          Additional ETC:  As noted in footnote 4, supra, prior to the 
closing of the Transaction, PSCo expects to establish a new ETC which will 
sell, finance, install, and service satellite receiver dishes and a variety 
of ancillary components to enable customers to receive direct broadcast 
satellite service.  This company will become a direct subsidiary of NC 
Enterprises after the closing of the Transaction.

                    III.  SUBSIDIARIES AND OPERATIONS OF PSCO

          1480 Welton:  1480 Welton holds certain of PSCo's real estate used 
or intended to be used in the utility business of PSCo, is functionally 
related to the utility operation of PSCo and is retainable.  1480 Welton does 
not hold interests in any other types of properties, nor does it offer 
services to non-system companies.  The Commission has permitted a number of 
registered holding company systems to establish and/or retain real estate 
subsidiaries.  See, e.g., UNITIL Corporation, HCAR No.  25524 (April 24, 
1992) (UNITIL Realty); The Southern Company, HCAR No. 21898 (January 27, 
1981) (Alabama Property Co. subsidiary of Alabama Power Co.); America 
Electric Power, HCAR No. 7615 (August 2, 1947) (Franklin Real Estate Co. and 
Indiana Franklin Realty Co.).

          Fuelco:  Fuelco was formed to engage in natural gas and oil 
exploration and production.  The Commission has approved the oil and 


                                     -71-

<PAGE>

gas exploration and development activities of New England Energy Incorporated 
("NEEI"), the subsidiary of New England Electric System.  New England Energy 
Incorporated, HCAR No. 23988 (Jan. 13, 1986); New England Energy 
Incorporated, HCAR No. 21862 (Dec. 30, 1980).  Fuelco's activities are 
functionally related to utility operations and is thus retainable.  In any 
event, Fuelco is now a corporation in dissolution under Colorado law, and 
substantially all of Fuelco's assets have been sold.

          Green and Clear Lakes and Ditch Companies:  Green and Clear Lakes 
stores water for use by a PSCo hydroelectric facility, a business that 
clearly is functionally related to utility operations.  The Ditch Companies 
own utility water rights that are also clearly functionally related to 
utility operations. Indeed, at the time of the break-up of the Cities Service 
holding company system, the Commission noted that the Ditch Companies could 
be retained by PSCo under the standards of Section 11(b)(1). In the Matter of 
Cities Service Power & Light Company, HCAR No. 4489 (Aug. 18, 1943). 

          PSRI:  PSRI owns certain life insurance policies acquired prior to 
1986 on certain PSCo employees and retirees.  PSRI does not intend to acquire 
any new policies or engage in any other active business.  Moreover, 
divestiture or the early winding-down of PSRI could have adverse tax 
consequences for PSCo. In addition, PSRI accounts for only 1.4% and 1.6% of 
PSCo's consolidated revenue in the years ended December 31, 1995 and December 
31, 1996, respectively.

          Thermal energy business:  The thermal energy business of PSCo, 
which is located exclusively in its service territory and primarily in the 
downtown Denver area, serves 120 customers and has annual revenues of 
approximately $6.7 million.  PSCo also intends to utilize and market the 
capacity and expertise developed in its thermal operations in different 
situations such as by offering chilled water services to existing customers, 
and providing services to maintain customer's heating and cooling plants.  
The thermal business is currently a division of PSCo, but may be moved to a 
separate subsidiary, either of NC Enterprises or PSCo.

          The retention of this business will further NCE's ability to be an 
energy service company providing consumers with all options to meet their 
energy needs.  Although much of the steam is supplied from boilers at PSCo's 
Denver steam plant, the steam system is connected to the Zuni steam electric 
generating plant as well, and approximately one-quarter of the steam heating 
business requirements are met through steam produced by this electric 
generation plant in the course of its ordinary operation.  The Commission has 
previously approved of the retention of steam heating operations under 
Section 11(b)(1).  See North American Company, 11 SEC 194 (1942); In the 
Matter of the Philadelphia Company, HCAR No. 8242 (June 2, 1948).

          Of course, PSCo is aware that the Commission in 1943 in the Cities 
Service case found similar operations of PSCo to be non-


                                     -72-

<PAGE>

retainable.(49)  That fact, however, is not dispositive here as, unlike at 
that time, the system is now connected with a PSCo generation facility and 
uses the steam produced by a facility that is also used for electric 
generation, and the nature of utility services has changed since that time.  
The retention of steam heating operations will allow NCE to offer customers 
this additional option to meet their energy needs, thereby allowing NCE to 
compete more effectively in the energy-services business.  The Commission has 
recently found district cooling and heating services to be permissible under 
the Act. Cinergy Corp., HCAR No. 26474 (February 20, 1996).  Moreover, "[t]he 
production, conversion, sale, and distribution of thermal energy products, 
such as process steam, heat, hot water, chilled water, air conditioning, 
compressed air and similar products" is an enumerated energy-related activity 
in Rule 58(b)(1)(vi). Thus, this thermal energy business of PSCo is 
reasonably incidental to NCE's utility operations and may be retained.

          Commercialization of electro-technologies and intellectual 
property: PSCo also markets non-utility products and services developed 
through electric utility operations.  For example, PSCo currently provides 
relay testing services for customers and may lease or sell surge protection 
equipment to unaffiliated third parties as well as install, own and operate 
photovoltaic cells, and commercialize other electro-technologies that become 
available to it. Similarly, PSCo may sell or enter into royalty arrangements 
with regard to intellectual property owned or developed by PSCo in its 
utility operations.(50)  Such commercialization activities are energy related 
activities as defined in Rule 58(b)(1)(ii) and, as discussed with regard to e 
prime's proposed meter reading services, commercialization of technology 
developed in utility operations has been previously authorized by the 
Commission (See also American Electric Power Company, HCAR No. 22468 (April 
21, 1982) (authorizing sale and licensing of intellectual property developed 
by utility system companies)).

          Electric and gas vehicle products and services:  In addition to the 
activities of Natural Fuels, as described above, PSCo is currently engaged in 
a program to develop fueling sites for natural gas vehicles.  The fueling 
units will be owned by PSCo and are typically located at PSCO facilities.  
PSCO also has located fueling equipment at certain customer facilities.  In 
addition, PSCO leases gas compressors, which are used for vehicle fueling 
purposes, to certain alternative fuel customers located within its service 
territory.  NCE through PSCo or another subsidiary may expand its activities 
to own, operate, sell, install and service recharging and 

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

(49)  The Commission did not require divestiture of the operations in 1943 as 
it recognized they were unprofitable and PSCo was unlikely to be able to 
divest them.

(50)  In the event these arrangements are with affiliates, the royalty payment 
provisions set out in Northeast Utilities, HCAR No. 25900 (September 30, 
1996), discussed with respect to e prime, will apply.


                                     -73-

<PAGE>

conversion equipment and facilities, and otherwise promote electric powered 
vehicles.  Such activities relating to electric vehicles are energy-related 
under Rule 58(b)(1)(iii) for NCE, as a registered holding company whose 
operating companies are primary electric utilities.  Moreover, because PSCo 
is a combination gas and electric utility, its fueling business for gas 
powered vehicles should be retainable for the reasons discussed with respect 
to Natural Fuels' activities.

          Sale and servicing of electric and gas appliances:  PSCo's 
appliance service operations provide repair services and warranties to 
customers in connection with certain household appliances and may involve the 
leasing of certain large appliances (i.e. HVAC system. lighting system, 
chillers) to industrial customers.  In Mississippi Power & Light Co., HCAR 
No. 25140 (August 30, 1990), the Commission authorized Mississippi Power & 
Light Co. to market and sell manufacturers' warranties and service agreements 
for space conditioning equipment as well as to market, sell, lease, and 
finance the acquisition and installation of surge suppressors.  PSCO's 
activities are similar and are, therefore, retainable.  Such activities 
should also be retainable for the reason set forth above with respect to 
Quixx's financing for heat pump acquisition by SPS customers.  Also, by 
analogy, Rule 48 provides various exemptions for a public-utility company, 
such as PSCo, to provide financing for customer purchases of, including from 
such public-utility company engaged in the business of selling, standard 
electric and gas appliances. Moreover, "[t]he sale of electric and gas 
appliances . . . and the installation and servicing thereof" are 
"energy-related" activities under Rule 58(b)(1)(iv).

                    IV.   LEASING OF SPACE BETWEEN AND AMONG   
                          ASSOCIATE COMPANIES

          SPS, PSCo, and other associate companies of NCE may, from time to 
time, enter into leases of office or other space with other associate 
companies. Any such lease will be in accordance with Rules 87, 90, and 91, 
except as may be otherwise authorized by the Commission.  To the extent 
necessary, NCE requests authority from the Commission to enter into the 
business of leasing such space between and among associate companies and 
third parties.  The Commission has permitted the leasing of excess office 
space.  See, e.g., Central Power and Light Company, HCAR No. 26408 (November 
13, 1995); Northeast Utilities, HCAR No. 24908 (June 22, 1989).

                    V.    APPLICABILITY OF THE 15% OF NET  
                          CAPITALIZATION TEST UNDER RULE 58

          As detailed above, many of the non-utility activities of NCE and 
its affiliates fall within the ambit of newly adopted Rule 58.  Rule 58 also 
provides (in section (a)(1)(ii)) that investments in non-utility activities 
that are exempt under Rule 58 cannot exceed 15% of the consolidated 
capitalization of the registered holding company.  In its statement 
supporting the adoption of the Rule, the Commission stated:


                                     -74-

<PAGE>

          The Commission believes that all amounts that have actually been
          invested in energy-related companies pursuant to commission order
          prior to the date of effectiveness of the Rule should be excluded from
          the calculation of aggregate investment under Rule 58.  The Commission
          also believes it is appropriate to exclude from the calculation all
          investments made prior to that date pursuant to available exemptions.

HCAR No. 26667 at 50-51.

          Because NCE was not yet a holding company, none of the investments 
in non-utility activities that are described herein were pursuant to 
Commission order.  However, since all of the activities of SPS were outside 
the ambit of the Act and since the non-utility investments of PSCo, an exempt 
holding company, were exempt under the Act, investments made by SPS and PSCo 
prior to the effective date of Rule 58 which will continue as part of the NCE 
holdings after consummation of the merger, should not count in the 
calculation of the 15% maximum.  The same reasoning that led the Commission 
to exempt prior investments for registered holding companies, justifies 
exempting from the 15% calculation the existing investments of a company 
about to be registered.  As stated in the Rule, all additional investments 
made in those activities subsequent to the adoption of Rule 58 should be 
included in the 15% test.(51)  

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

(51)  At December 31, 1996, the combined equity investment in non-utility 
companies by PSCo and SPS totaled $177,465,000, with total assets of these 
non-utility companies amounting to $446,548,000.  PSCo's and SPS's respective 
portions of this equity investment and total assets were $65,528,000 equity 
investment and $318,221,000 total assets by PSCo; and $111,937,000 equity 
investment and $128,327,000 total assets by SPS.  PSCo's subsidiary PSCCC, 
which as of December 31, 1996 had assets of $174,528,000 and a PSCo equity 
investment of $20,911,000, accounted for more than half of the December 31, 
1996 non-utility assets of PSCo.  The combined non-utility companies' equity 
investment and total asset numbers above include the following investment and 
asset amounts attributable to EWGs and FUCOs:

          b.   SECTION 10(c)(2)

          The Transaction 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.

               i.   EFFICIENCIES AND ECONOMIES

          The Transaction will produce economies and efficiencies more than 
sufficient to satisfy the standards of Section 10(c)(2), described above. 
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 
American Electric Power Co., 46 SEC 1299, 1320-1321 (1978).  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., 
HCAR No. 24073 (April 29, 1986) (citation omitted).

          At the time of the announcement of the Transaction, PSCo and SPS 
estimated the nominal dollar net value of synergies from the Transaction to 
be approximately $770 million over the first 10-year period from 1997 to 
2006.  The Transaction is expected to yield several types of presently 
quantifiable benefits:  (1) capital expenditure savings; (2) production cost 
savings; (3) labor cost savings; and (4) administrative and general savings.  
The amount of savings estimated at the time of announcement of the 
Transaction in each of these categories, on a nominal dollar basis, is 
summarized in the table below:

*Net of the estimated cost of building the planned interconnection between 
PSCo and SPS.  See discussion under "Capacity Deferrals" below.

          These expected savings far exceed the savings claimed in a number 
of recent acquisitions approved by the Commission.  See, e.g., Kansas Power 
and Light Co., HCAR No. 25465 (Feb. 5, 1992) (expected savings of $140 
million over five years); IE Industries, HCAR 


                                     -76-

<PAGE>

No. 25325 (June 3, 1991) (expected savings of $91 million over ten years); 
Midwest Resources, HCAR No. 25159 (Sept. 26, 1990) (estimated savings of $25 
million over five years).  These savings categories are described in greater 
detail below.

          Corporate Programs:  These are savings related to insurance costs,
     outside services, shareholder services, advertising and other general and
     administrative overheads.  The aggregate cost of these items for the
     companies on a stand-alone basis is greater than the cost will be to the
     combined new company.  An example would be the hiring of one outside
     professional service (e.g., external auditors, attorneys, and consultants)
     instead of two.

          Non-Fuel Purchasing Economies:  These are the savings which will
     result from the new, larger company having greater purchasing power.  The
     new company will be able to coordinate its purchasing needs, buy in greater
     quantity, negotiate with vendors, and receive larger discounts.

          Capacity Deferrals:  This refers to the savings created by deferring
     the construction of additional generating capacity.  For these deferrals to
     be achieved, the two systems must be integrated via a HVDC interconnection
     and transmission line.  Because of load diversity (the two systems peak at
     different times) the new company's peak load is less than the sum of the
     peak loads of the two individual companies.  This load diversity requires
     less total capacity, allowing the new company to defer generation expansion
     and the associated costs to the ratepayer.  The amount of projected
     capacity deferral savings is net of the estimated incremental merger-
     related cost of the HVDC interconnection and transmission line
     (approximately $112 million).  See Item 3.A.2.b.ii.I for details of the
     interconnection and line.

          Fuel Savings:  These are savings which result from the new, larger
     company having greater purchasing power.  The new company will be able to
     negotiate contracts to procure and transport fuel in larger quantities, and
     at much larger discounts than either PSCo or SPS would on a stand-alone
     basis. Additionally, once the two systems are directly interconnected, the
     new company's operators will be able to dispatch and generate the power in
     the most economic manner, as certain plants are more economical than
     others. 

          Labor Cost Savings:  PSCo and SPS estimate that a net reduction in
     labor costs of at least $389.5 million on a nominal dollar basis can be
     achieved as a result of the Transaction through elimination of
     approximately 550-600 or more full time equivalent duplicative positions in
     certain corporate and administrative functions.  This assumes a one-year
     period will be required to achieve the personnel reductions.

     (less)


                                     -77-

<PAGE>

          Pre-Merger Initiatives:  The level of employees of both companies
     combined compared with the level of employees needed for the new company
     indicates that approximately 550-600 or more full-time duplicate positions
     be eliminated through the merger process.  There is, however, a level of
     employee reduction which will occur regardless of the merger.  This figure
     is a part of the total labor savings amount above, and is removed from the
     savings estimates to avoid double counting of savings for forecasting
     purposes

          Costs to Achieve:  This consists of merger costs such as investment
     bankers' fees, attorney and accountant fees, and severance and other
     employee reduction-related costs.  Item 2 provides details of some of these
     components and their amounts.

          Additional Expected Benefits:  In addition to the benefits 
described above, there are other benefits which, while presently difficult to 
quantify, are nonetheless substantial.  These other benefits include 
competitive rates and services, increased size and stability, diversification 
of service territory, coordination of diversification programs, complementary 
operational functions, and complementary management.

     -    COMPETITIVE RATES AND SERVICES -- NCE will be able to meet the
          challenges of the increasingly competitive environment in the utility
          industry more effectively than either PSCo or SPS standing alone.  The
          Transaction will create financial and operational benefits for
          customers in the form of lower rates and better service over the long-
          term.

     -    INCREASED SIZE AND STABILITY -- As a larger entity, shareholders will
          benefit over the long-term from the NCE's greater financial strength
          and financial flexibility.  NCE will be better able to take advantage
          of future strategic opportunities and to reduce its exposure to
          changes in economic conditions in any segment of the business.

     -    DIVERSIFICATION OF SERVICE TERRITORY -- The combined service
          territories of PSCo and SPS will be larger and more geographically
          diverse than the independent service territories of each entity,
          reducing NCE's exposure to changes in economic, competitive, or
          climatic conditions in any given sector of the combined service
          territory.

     -    COORDINATION OF DIVERSIFICATION PROGRAMS -- PSCo and SPS each have
          complementary non-regulated subsidiary businesses, and NCE, as a
          stronger financial entity, should be able to manage and pursue these
          subsidiary businesses more efficiently and effectively as a result of
          access to lower-cost capital and efficiencies achievable through
          greater size.

     -    COMPLEMENTARY OPERATIONAL FUNCTIONS -- The combination of PSCo, with
          expertise in customer service applications and 


                                     -78-

<PAGE>

          energy services as well as natural gas utility operations, and SPS, 
          a low-cost power producer with recognized expertise in engineering 
          services, wholesale power marketing and utility generation 
          projects, will allow NCE to offer customers a more complete menu of 
          service options and a better operational balance.

     -    COMPLEMENTARY MANAGEMENT -- The managements of PSCo and SPS have
          complementary strengths which will provide NCE with a strong and
          capable management team, facilitating the merger of similar corporate
          cultures and achieving cooperation and coordination in an efficient
          manner.

               ii.  INTEGRATED PUBLIC UTILITY SYSTEM

          Reference is made to Item 3.A.2.a. for a discussion of the retention
of both NCE's electric and gas utility businesses.  In the Commission's decision
In the Matter of American Water Works and Electric Company, Incorporated, 2 SEC
972 (1937), it was noted that the Act does not contain a definition of a single
integrated utility in the context of a combined company:

          We believe, however, that it is proper to regard such a combined
          property as a single integrated system, provided that all of the
          electric properties are integrated and all of the properties, both gas
          and electric, are in fairly close geographic proximity and are so
          related that substantial economies may be effectuated by their
          coordination under common control.

As is pointed out in Item 3.A.2.a. above, the Transaction meets the requirements
necessary for NCE to remain a combination gas and electric utility holding
company.  NCE also meets the standards of Section 2(a)(29)(A) and (B) of the Act
with respect to its electric operations and gas operations.

                    I.    ELECTRIC 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 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.


                                     -79-

<PAGE>

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
public utility 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. 

Environmental Action, Inc. v. Securities and Exch. Comm'n, 895 F.2d 1255, 1263
(9th Cir. 1990) (citing In re Electric Energy, Inc., 38 SEC 658, 668 (1958)). 
The Transaction satisfies all four of these requirements.  It should be noted
that 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."(52)

          At the moment, PSCo and SPS have the ability to exchange power over a
transmission tie owned by Public Service Company of New Mexico ("PNM").  In the
past, the two companies have exchanged electric energy utilizing these
facilities.  Facilitating the current transmission and exchange of power between
the parties is participation by PSCo, SPS and PNM in the WSPP, which provides
for, among other things, the exchange of bulk power.

          The Section 2(a)(29) standard will be met in this Transaction,
however, as the NCE system is capable of interconnection through the
construction of a new transmission tie line, construction of which is planned
within five years of the effective time of the Transaction.  NEC is committed to
the construction of this transmission tie line.  Present plans are to complete
the interconnect by the year 2001.  For purposes of estimating merger savings,
PSCo and SPS assumed that the tie line would be approximately 300 miles, running
from near Amarillo, Texas to Southeastern Colorado, and that the tie line
voltage would be 345 KV.  They also estimated that the costs associated with
constructing the interconnection line amount to $149 million, of which
$112 million are incremental costs attributable to the Transaction.  However,
the actual routing and cost of the tie line has not yet been finally determined.
In conjunction with a settlement of the FERC merger proceeding, SPS and PSCo
have agreed

with other utilities to comprehensive procedures for regional planning of the 
new transmission interconnection between SPS and PSCo.  See Exhibit D-1.4, 
hereto.  The procedures will allow for the participation of all interested 
parties in the identification and evaluation of transmission line 
alternatives to connect the PSCo and SPS systems.  Following completion of 
the line, the PSCo and SPS systems will be operated as a single 
interconnected system.  The initial open planning meeting, as contemplated in 
the settlement agreement, was held on October 3, 1996.  Since that time a 
study committee has been established among the open study participants (not 
simply PSCo and SPS). The study committee has identified alternative routes 
to be evaluated.

          Since SPS operates in the Eastern Interconnection and is a member 
of the SPP and PSCo is in the Western Interconnection and is a member of the 
WSCC, the interconnect must include at least one HVDC back-to-back terminal 
between the two systems.  The HVDC terminal included for purposes of 
estimating merger savings to asynchronously connect the two companies was 
expected to be rated at 400 MW and allow for capacity and energy transfers 
between the two systems.(53) However, it is possible that one or more such 
interconnects could be constructed.

          This additional interconnect will further the economic operation of
the NCE system by enabling it to achieve additional production-related
synergies.  Indeed, the plans for the line's construction are not related to any
requirement of the Act, but rather to the substantial benefits that will accrue
as a result of the line.  As recently as 1992, SPS and PSCo discussed connecting
their systems through an HVDC tie and transmission line to facilitate
transactions between their systems.  The production-related benefits of the
proposed interconnect were determined in three areas:  capacity deferral
savings, joint dispatch savings, and fuel energy savings.  The process used to
estimate these savings involved modeling each company's system and determining
its costs on a stand-alone basis and then on a combined basis.  The savings were
based on a comparison of the individual system costs to those determined on a
combined basis.  The representation of the individual systems was based on each
company's most recent resource plan, modified to account for any major changes
in assumptions since the plan was developed, and the most recent fuel forecasts.
The combined system expansion plan was based on the reduced capacity
requirements of the combined system and accounted for the expected fuel synergy
savings.  The development of these costs considered production costs as well as
investment-related costs.  Benefits attributed to joint dispatch savings were
developed


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

(53)  This is exactly the type of asynchronous interconnection approved by 
the Commission in connection with a settlement that provided for the 
construction by the Central and South West Corporation of two HVDC ties to 
interconnect its ERCOT subsidiaries with its Southwest Power Pool 
subsidiaries, thereby satisfying the Act's integration requirements.  See 
Central and South West Corporation, HCAR No. 22439 (April 1, 1982).

within the combined system model and coincide with the in-service date of a 
new transmission line between the two companies.  Overall, it is anticipated 
that the electric production-related savings from the merger of PSCo and SPS 
will aggregate approximately $270 million (net of the cost of the line). To 
achieve this level of savings, the tie-line will need to be constructed. 
Additional savings are likely to be realized over time.  Additional 
information regarding electric production-savings can be found in Exhibit 
D-1.2.2. attached hereto.

          The Commission has previously indicated that a single integrated 
system exists even based solely on a planned, future interconnection, 
provided that such physical interconnection is "contemplated or . . . 
possible within the reasonably near future" and not just something that 
"might occur in the remote future, and whose occurrence has not been 
foreshadowed by any facts shown in the record."(54) The benefits to be 
derived by the new transmission line are also a factor in determining whether 
the system is capable of physical interconnection.(55) The fact that the 
Commission has indicated that, absent special circumstances, the "reasonably 
near future" mentioned above, should not exceed 10 years,(56) is not an issue 
in this case as the parties do have definite plans to construct an 
interconnection that will be in service and generating economies within 5 
years of the consummation of the Transaction.

          In addition, Cheyenne forms a single integrated system with the NCE 
system.  With regard to electric properties and as set forth above,(57) the 
key to a single integrated system is that the utility assets are "physically 
interconnected or capable of interconnection."

Historically both Cheyenne and PSCo were part of the Cities Service Power and 
Light Company holding company system.  When the Commission ordered the 
break-up of that system in the mid-1940s, it issued orders organizing the 
various systems within the Cities Services system as independent systems.  At 
that time, the Commission specifically examined the relationship between the 
electric utility operations of PSCo and Cheyenne and held that together they 
constituted a single integrated system within the meaning of Section 2(a)(29) 
of the Act.(58) The Commission noted that the two systems were interconnected 
via "a transmission line which functions as an important tie between the 
companies although it is owned, not in the system, but by the United States 
Bureau of Reclamation."(59) Moreover, although the Commission initially 
postponed any finding on the issue of PSCo's retention of combination gas and 
electric utility properties, it did examine the PSCo and Cheyenne gas 
operations as one unit.(60) PSCo and Cheyenne continue to form such an 
integrated system and the addition of NCE as a holding company above these 
entities does not alter that fact, nor does the fact that the NCE system will 
include SPS utility properties since, as described above, PSCo and SPS will 
be interconnected and PSCo and Cheyenne are interconnected.  Thus, the entire 
system is, or is capable of being, interconnected.

          The specific physical interconnection via electric transmission ties
between PSCo and Cheyenne is as follows:  115KV transmission lines owned by WAPA
connect with the Cheyenne system via the Happy Jack, Cheyenne and Archer
substations.  WAPA transmission lines also interconnect with PSCo transmission
lines.  One of these WAPA owned lines connects PSCo and Cheyenne, running
directly from a WAPA-PSCo interconnection to a WAPA-Cheyenne interconnection. 
Indeed, the Applicants believe that this line is the same line referred to in
the Cities Service decision.

          It should be noted that Cheyenne was receiving electricity from 
PSCo via this line at the time of the Cities Service decision, while today, 
as a result of a competitive bid process to supply the Cheyenne system, 
Cheyenne currently receives its power requirements to serve its load from a 
thirty-party utility, PacifiCorp, in accordance with an agreement that 
expires in the year 2000.  That fact should not prevent the conclusion that 
the PSCo and Cheyenne electric systems constitute a single integrated 
electric system within the meaning of Section 2(a)(29).  PacifiCorp was 
selected as Cheyenne's power supplier in a competitive resource selection 
process in which PSCo participated. Had PSCo won the bidding process, it 
could have met Cheyenne's power

requirements.  Moreover, Cheyenne's use of competitive resource selection 
procedures is consistent with the preferences of the WPSC, as reflected in 
the Stipulation and Agreement that Cheyenne reached in the proceeding on the 
PSCo and SPS merger, which the WPSC had to approve because it involved a 
change of control of Cheyenne.  As set forth in section 4(a) thereto:

          Unless and until Cheyenne proposes and discusses alternative resource
          selection procedures with the Commission, Cheyenne commits that,
          following the consummation of the merger of PSCo and SPS, and the
          formation of NCE, it will continue to use the resource planning and
          bidding techniques and methods it used during its last competitive
          electric resource solicitation, which resulted in the selection of
          PacifiCorp as Cheyenne's full requirements electricity provider
          through December 31, 2000.  In this connection, Cheyenne will provide
          written notification to and consult with the Commission before
          agreeing to engage in joint resource planning with PSCo and SPS.

The Stipulation and Agreement is included as an attachment to Exhibit D-3.2 to
this Application.  Moreover, the third-party relationship demonstrates adherence
to a policy the Act is intended to promote:  the prevention of affiliate abuse. 
That is, Cheyenne has in the past and will in the future choose its power
supplier irrespective of corporate relationships.  As a final point, the general
manager of the Cheyenne system has historically reported to the vice president
of electric and gas distribution in PSCo.

          Additionally, notwithstanding that Cheyenne currently obtains its
power requirements from PacifiCorp rather than PSCo, Cheyenne and PSCo
coordinate operations in other ways.  For example, PSCo currently provides
significant system support services for Cheyenne, including emergency support,
system design, construction and operation, and maintenance activities.  PSCo
administers the joint PSCo/Cheyenne transmission tariff on behalf of both
companies.  PSCo provides a variety of administrative and general services in
support of Cheyenne, including rate and regulatory support, legal support,
accounting support, and technical assistance.  As an example of the services
PSCo provides to Cheyenne, in Cheyenne's last competitive solicitation, certain
departments in PSCo helped Cheyenne evaluate the bids and select PacifiCorp as
its supplier, even though PSCo itself had put in a bid to supply Cheyenne.

          The NCE electric system will operate in a single area or region.  The
system will operate in six contiguous states in the greater southwest region of
the United States.  It should be noted that in the 1995 Report, the Division has
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 distance, and other developments in the industry, such as brokers
and

                                     -84-
<PAGE>

marketers, that affect the concept of geographic integration."(61) The 
1995 Report also recommends primacy be given to "demonstrated economies and 
efficiencies to satisfy the integration requirements."(62) As set forth in 
Item 3.A.2.b.i, the Transaction will result in economies and efficiencies for 
the utilities and, in turn, their customers.

          Moreover, the NCE electric system will not be so large as to impair
the advantages of localized management, efficient operations, and the
effectiveness of regulation.  After the Transaction, PSCo, SPS and Cheyenne will
maintain their current headquarters as subsidiary headquarters and as local
operating headquarters for the areas they presently serve, while NCE maintains
system headquarters in both Denver (corporate offices) and Amarillo (operating
offices).  This structure will preserve all the benefits of localized management
PSCo, SPS, and Cheyenne presently enjoy while simultaneously allowing for the
efficiencies and economies that will derive from their strategic alliance. 
Furthermore, as described earlier, the system will facilitate efficient
operation.

          Additionally, the NCE system will not impair the effectiveness of 
state regulation.  PSCo, SPS, and Cheyenne 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 
CPUC, WPSC, PUCT, NMPUC, KCC, OCC, and the FERC.  PSCo and SPS have worked, 
and are continuing to work, closely with the CPUC, WPSC, NMPUC, PUCT, KCC, 
and OCC as well as the FERC and the NRC, to ensure they are well informed 
about this Transaction, and public hearings have been held by the CPUC, 
WPSC, PUCT, NMPUC, and FERC as part of the process of obtaining the required 
regulatory approvals for the Transaction.  Furthermore, all required state 
regulatory approvals (as well as the approval of FERC and the NRC) have been 
obtained.  Pursuant to the recommendations contained in the 1995 Report, this 
last factor is significant as the Division stated therein "when the affected 
state and local regulators concur, the [Commission] should interpret the 
integration standard flexibly to permit non-traditional systems if the 
standards of the Act are otherwise met,"(63) especially since this 
Transaction will result in a system similar to the traditional registered 
holding company system.

                    II.  GAS UTILITY SYSTEM

          As discussed in Item 3.A.2.a.i, NCE seeks retention of the PSCo and
Cheyenne gas systems on a separate system basis, not as a single integrated gas
system.  Nevertheless, NCE believes that an argument can be made that the PSCO
and Cheyenne gas systems can be

<PAGE>

considered a single integrated gas utility system within the meaning of the 
Act and consistent with Commission precedent.

          To elaborate, the two operations are physically connected by the
WestGas interstate transmission pipeline (owned by WGI) which connects to the
PSCo transmission system at Chalk Bluffs, Colorado near the Colorado-Wyoming
border and runs to Cheyenne, Wyoming.  Although PSCo and Cheyenne each maintain
separate gas supply and capacity portfolios that are consistent with the
requirements of their respective systems, they nevertheless, through the WGI
pipeline, derive gas from common sources of supply.  PSCo and Cheyenne also
derive gas from common sources through the Colorado Interstate Gas Co.
transmission system, to which both companies are connected.  Moreover, their gas
portfolios are managed by a central supply and capacity organization within
PSCo, and their operations will continue to be centralized by NC Services after
the merger.  Further, PSCo's and Cheyenne's gas systems are monitored and
operated from the same Gas Load Control Center located in Golden, Colorado.  The
operating pressures on both systems can be affected simultaneously by the valve
settings and compression utilized by WGI.  In these circumstances, the
Commission could find the PSCo and Cheyenne gas systems to be a single
integrated utility system for purposes of the Act.  See MCN Corporation, HCAR
No. 26576 (September 17, 1996) (Commission finding non-contiguous local
distribution companies to be part of an "integrated public utility system"
where, among other things, the local distribution companies were interconnected
through common pipelines and obtained gas from a common source).

     3.   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 to 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.

As described in Item 4 of this Application/Declaration, and as evidenced by the
orders issued by the CPUC, WPSC, PUCT, NMPUC, and the KCC all relating to the
Transaction, NCE has complied with all applicable state laws related to the
proposed transaction.

     4.   OTHER APPLICABLE PROVISIONS -- SECTION 9(a)(1)

          NCE is also requesting authorization from the Commission under
Section 9(a)(1) of the Act for the acquisition by it of the voting securities of
NC Services and NC Enterprises as part of the Transaction.  Section 9(a)(1) of
the Act requires a registered holding company or any subsidiary thereof to
obtain authorization from the Commission before acquiring "any securities or
utility assets or any other interest in any business."  In order to approve an
acquisition


                                     -86-
<PAGE>

under Section 9(a)(1), the Commission must find that such acquisition meets 
the standards of Section 10 of the Act, which in turn requires compliance 
with Section 8 and 11 of the Act.  Although NCE will not become a registered 
holding company until consummation of the Transaction and thus Section 
9(a)(1) is not applicable to it until that time, because NCE will become 
subject to Section 9(a)(1), NCE is requesting the Commission's authorization 
for these transactions.

          The acquisition by NCE of the common stock of NC Services, making it a
wholly-owned subsidiary of NCE, will allow NCE to create a subsidiary service
company and capture economies of scale from the centralization of administrative
and general services to be provided to system companies.  Since the cost of such
services are considered in rate cases, many of the benefits realized as a result
of NC Services will accrue to NCE's ratepayers.  Virtually every registered
holding company has a subsidiary service company performing many of the same
functions as NC Services will perform.  The acquisition of NC Services is in the
public interest, will not unduly complicate the capital structure of NCE, and
will not cause the NCE system to violate any other provision of the Act.  NC
Services' only class of authorized stock will be its common stock, all of which
will be owned by NCE.  The operation of NC Services, and the allocation of cost
for its operation, is discussed in detail in Item 3.B below.

          NCE is also requesting authorization to acquire all of the issued and
outstanding common stock of NC Enterprises, which will serve as an intermediate
holding company for certain of the system's non-utility subsidiaries and
investments.  NCE believes that an intermediate holding company provides a
clearer separation between the system's utility and non-utility operations and
allows for centralization of the operation of the non-utility operations. 
Although NC Enterprises will have issued and have outstanding debt to SPS (in
connection with NC Enterprises's acquisition of UE and Quixx) as part of the
Transaction, this should not unduly complicate the NCE system's capital
structure.  While NC Enterprises will have a board of directors, appointed
officers and, possibly, employees, it also will receive services from NC
Services.  Costs for any work performed for NC Enterprises by NC Services will
be charged to NC Enterprises in accordance with the appropriate allocation
method set forth in the Non-Utility Service Agreement.

          NC Enterprises requests authorization under Section 9(a)(1) of the Act
to acquire all of the issued and outstanding common stock of e prime, UE, Quixx,
and Natural Fuels.  As discussed in Item 3.A.2.a.ii above, each of these
businesses may be retained by the NCE system under the Act.  NCE believes that
the reorganization of these non-utility businesses as subsidiaries of NC
Enterprises instead of as subsidiaries of either PSCo or SPS directly, will be
beneficial to ratepayers by providing a clearer separation between the system's
utility and non-utility operations and by insulating the operating utilities
from the results of operations of these entities.  NC Enterprises will directly
acquire the securities of certain current PSCo subsidiaries via an equity
contribution from NCE.  In order to maintain the current equity capitalization
of SPS, NC Enterprises will


                                     -87-
<PAGE>

issue debt to SPS in exchange for the securities of UE and Quixx.  The 
acquisitions of Quixx and UE are proposed to be consummated as sales for debt 
in order to preserve the capital structure of SPS and the NMPUC has ordered 
such sale at the companies' fair market value, which SPS anticipates will 
approximate equity value.  The equity of the two subsidiaries at December 31, 
1996 and December 31, 1995, respectively, was valued at $111.9 million and 
$95.0 million, or approximately 15% and 13% of SPS's equity of $731.8 million 
and $727.9 million.  Transferring the subsidiaries by payment of a dividend 
of their stock would cause a reduction of SPS's equity by this same amount.  
This would be viewed negatively from a regulatory and rating agency point of 
view.  Selling the subsidiaries eliminates this adverse impact on SPS.

          The debt issued by NC Enterprises will have a thirty year maturity and
bear interest at a fixed rate.  The interest rate will be determined at the time
of issuance based on the then prevailing rate which would be charged by an
unaffiliated third party.  Interest only will be paid for the first three years
and thereafter interest and principal will be amortized over the remaining 27
years payable in equal annual installments.  NC Enterprises will have the option
to prepay the entire obligation, including accrued and unpaid interest, at any
time without any prepayment premium.  The form of note to be used to evidence
the debt of NC Enterprises is attached as Exhibit J-5.  NC Enterprises expects
to have sufficient earnings to service the debt based on the expected earnings
of UE and Quixx after the first four years.  See Exhibit J-4.  Prior thereto, NC
Enterprises will also have available the earnings of its other subsidiaries and
other sources of cash to meet its obligation under the Note.  Because NC
Enterprises may be considered to be thinly capitalized for accounting purposes,
it may be necessary for NCE to guarantee this debt in order for the transfer of
the shares by SPS to be considered a sale.  NCE accordingly hereby requests
authority to make such guarantee should it become so necessary.

          Finally, NCE, NC Enterprises, or e prime, as appropriate, requests
authorization under Section 9(a)(1) of the Act to acquire all of the issued and
outstanding common stock of NC International.

B.   INTRA-SYSTEM TRANSACTIONS

          The NCE system companies will engage in a variety of affiliate
transactions for the provision of goods, services, and construction.  Certain of
these transactions, and in some instances associated exemptions from the
Commission's Rules, are elaborated upon below.  The provision of goods,
services, and construction by NCE system companies to other NCE system companies
will be carried out in accordance with the requirements and provisions of Rules
87, 90, and 91 unless otherwise authorized by the Commission by order or rule.


                                     -88-
<PAGE>

     1.   SERVICES, GOODS, AND ASSETS INVOLVING THE UTILITY
          OPERATING COMPANIES

          PSCo, SPS, and Cheyenne may provide to one another and other associate
companies services incidental to their utility businesses, including but not
limited to, power plant maintenance overhauls, power plant and storm outage
emergency repairs, and services of personnel with specialized expertise related
to the operation of the utility (i.e., services by an industrial lighting
specialist or waste disposal specialist).  These services will be provided in
accordance with Rules 87, 90, and 91.  Moreover, in accordance with Rules 87,
90, and 91, certain goods may be provided through a leasing arrangement or
otherwise by one utility operating company to one or more associate companies,
and certain assets may be used by one utility operating company for the benefit
of one or more other associate companies.  For instance, PSCo's CIS System will
remain an asset of PSCo following the transaction.  While all required system
personnel involved in the operation of the CIS System will be employees of the
service company or external affiliated or unaffiliated contractors and all
charges for service company employees' labor will be subject to the terms of the
Utility Service Agreement, PSCo will charge associate companies for the actual
use of the CIS System in accordance with the Commission's Rules.  Likewise,
PSCo, SPS, and Cheyenne may obtain goods, services, and construction from
associated companies in accordance with Rules 87, 90, and 91.  Certain of these
transactions are discussed further below.

          With respect to affiliate transactions involving PSCo, SPS, and
Cheyenne, the FERC in its Order Establishing Hearing Procedures on the PSCo/SPS
merger, Docket No. EC96-2-000, 75 FERC PARA 61,325 (June 26, 1996), gave PSCo
and SPS the choice of following its affiliate pricing standards or having a
hearing on the issue of whether the proposed merger impairs effective
regulation.  The FERC's standards are as follows:

          (1) affiliates or associates of a public utility not sell
          non-power goods and services to the public utility at a
          price above market price; and (2) sales of non-power goods
          and services by a public utility to its affiliates or
          associates be at the public utility's cost for such goods
          and services or market value for such goods and services,
          whichever is higher.(64)

As PSCo and SPS explained in a letter responding to the FERC hearing order and
choosing not to have a hearing on this issue:

               In making this choice, Applicants note that affiliate
          transactions among the member companies of [NCE] will be subject to
          the jurisdiction of the [SEC] under [PUCHA] * * * including the
          requirements of section 13(b) of PUCHA and the 


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

(64) This order is included as Exhibit D-1.3.


                                    -89-

<PAGE>

          rules and regulations thereunder.  Section 13(b) of PUCHA generally
          provides that transactions between affiliates in a registered holding
          company system be "at cost, fairly or equitably allocated among such
          companies." Applicants believe that as a practical matter there should
          not be any irreconcilable inconsistency between the application of the
          SEC's "at cost" standard and the FERC's policies with respect to
          intra-system transactions as applied to Applicants.  For example,
          while Applicants intend to establish a service company, NC Services,
          Inc. ("NC Services"), to provide non-power goods and services to
          themselves and other associate companies within the NCE system at
          cost-based prices, they anticipate that NC Services will provide only
          those goods and services where it can meet or better market prices for
          comparable quality goods and services.  In other words, they are
          anticipating that NC Services "costs" will be at or below the market.
          In any event, even if some inconsistency were to develop, Applicants'
          agreement to the second option means that the FERC will continue to
          have full authority to disallow, for purposes of FERC-jurisdictional
          wholesale power and transmission rates, any charge to the extent of
          any inconsistency between the SEC "at cost" and FERC "cost or market"
          standards.

               Based on the above, Applicants will be able to comply with the
          requirements of both the FERC and the SEC. (65)

          The Applicants will comply with the "at cost" and fair and equitable
allocation of cost requirements of Section 13, including Rules 87, 90, and 91
thereunder, for all services, sale and construction contracts between associate
companies and with the holding company parent unless otherwise permitted by the
Commission by rule or order.

     2.   NC SERVICES

          As described in Item 1.B.1.c.v, NC Services will provide PSCo, SPS,
and Cheyenne, as well as NCE itself, WGI, and certain subsidiaries that support
utility operations, pursuant to the Utility Service Agreement, and non-utility
subsidiaries of the NCE system, and possibly other entities in which NCE has
investments, pursuant to the Non-Utility Service Agreement, with a variety of
administrative, management and support services, including services relating to
engineering, development, design, rehabilitation, maintenance, construction,
electric power planning, transportation, materials management, facilities and
real estate, accounting, budgeting and financial forecasting, finance and
treasury, rates and regulation, legal, internal audit, corporate communications,
environmental, fuel


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

(65) That letter is included as Exhibit D-1.4.  The FERC in its order 
approving the proposed merger indicated that in light of PSCo's and SPS's 
response, it "no longer [had] concerns with this issue"


                                     -90-
<PAGE>

procurement, corporate planning, investor relations, human resources, 
marketing and customer services, information systems, and general 
administrative and executive management services.  In accordance with the 
service agreements, services provided by NC Services will be directly 
assigned, distributed or allocated by activity, project, program, work order, 
or other appropriate basis.  NC Services will provide these services directly 
or may contract with non-utility affiliates, such as UE, for the needed 
services. Costs of NC Services will be accumulated in accounts of NC Services 
and directly assigned, distributed, and allocated to the appropriate client 
company in accordance with the guidelines set forth in the applicable Service 
Agreement. SPS and PSCo have developed the system and procedures necessary to 
implement the Service Agreements.  See form of the "NCE Policies and 
Procedures" manual filed with Exhibit B-6, hereto.

          NC Services will be staffed by transfer of personnel from PSCo, SPS,
and their subsidiaries.  NC Services' accounting and cost allocation methods and
procedures are structured so as to comply with the Commission standards for
service companies in registered holding-company systems.  NC Services will use
the "Uniform System of Accounts for Mutual Service Companies and Subsidiary
Service Companies" established by the Commission for service companies of
registered holding-company systems to develop its policies and procedures.

          As compensation for services, the Utility Service Agreement provides
for the client companies to:  "pay to [NC Services] all costs which reasonably
can be identified and related to particular services performed by [NC Services]
for or on its behalf."  Where more than one company is involved in or has
received benefits from a service performed, the Service Agreement provides that
"costs will be directly assigned, distributed or allocated, between or among
such companies on a basis reasonably related to the service performed to the
extent reasonably practicable," in accordance with the methods set forth in
Appendix A to the Service Agreement.  Thus, charges for all services provided by
NC Services to affiliated utility companies will be in accordance with Rules 90
and 91 of the Act.  The Non-Utility Service Agreement contains provisions
similar to those of the Service Agreement, except as set forth in detail below
in this Item 3.B.  The Non-Utility Service Agreement also permits charges for
certain services to be at fair market value to the extent authorized by the
Commission.  Thus, except for the requested exceptions discussed below, or as
otherwise approved by the Commission, services provided by NC Services to non-
utility affiliates pursuant to the Non-Utility Service Agreement will also be
charged in accordance with Rules 90 and 91 of the Act.

          No change in the organization of NC Services, the type and character
of the companies to be serviced, the methods of allocating costs to associate
companies, or in the scope or character of the services to be rendered subject
to Section 13 of the Act, or any rule, regulation or order thereunder, shall be
made unless and until NC Services shall first have given the SEC written notice
of the proposed change not less than 60 days prior to the proposed effectiveness
of


                                     -91-
<PAGE>

any such change.  If, upon the receipt of any such notice, the SEC shall 
notify NC Services within the 60-day period that a question exists as to 
whether the proposed change is consistent with the provisions of Section 13 
of the Act, or of any rule, regulation or order thereunder, then the proposed 
change shall not become effective unless and until NC Services shall have 
filed with the SEC an appropriate declaration regarding such proposed change 
and the SEC shall have permitted such declaration to become effective.

          NCE believes that the Service Agreement and the Non-Utility Service
Agreement are structured so as to comply with Section 13 of the Act and the
Commission's rules and regulations thereunder.

          Rule 88:  Rule 88 provides that "[a] finding by the Commission that a
subsidiary company of a registered holding company . . . is so organized and
conducted, or to be conducted, as to meet the requirements of Section 13(b) of
the Act with respect to reasonable assurance of efficient and economical
performance of services or construction or sale of goods for the benefit of
associate companies, at cost fairly and equitably allocated among them (or as
permitted by Rule 90), will be made only pursuant to a declaration filed with
the Commission on Form U-13-1, as specified" in the instructions for that form,
by such company or the persons proposing to organize it.  Notwithstanding the
foregoing language, the Commission has on at least two recent occasions made
findings under Section 13(b) based on information set forth in an Application/
Declaration on Form U-1, without requiring the formal filing of a Form U-13-1. 
See CINergy Corp., HCAR No. 26146 (Oct. 21, 1994); UNITIL Corp., HCAR No. 25524
(April 24, 1992).  In this Application/Declaration, NCE has submitted
substantially the same applicable information as would have been submitted in a
Form U-13-1.

          Accordingly, it is submitted that it is appropriate to find that NC
Services is so organized and its business will be so conducted as to meet the
requirements of Section 13(b), and that the filing of a Form U-13-1 is
unnecessary, or, alternatively, that this Application/Declaration should be
deemed to constitute a filing on Form U-13-1 for purposes of Rule 88.

     3.   NON-UTILITY SALE OF GOODS AND SERVICES TO EWGS,
          FUCOS, AND QFS

          Various non-utility companies in the NCE system, namely NC Services,
UE, Utility Services, PRC, QPS, and e prime, e prime Operating, NC
International, and ep3 (or successor company -- see note 48, supra)
(collectively, the "Exempt Companies"), currently are, or will in the future be,
providing services (including operation and maintenance) and selling goods to
associated EWGs and QFs or to entities that will qualify as QFs, EWGs, or FUCOs
following the Transaction.  The Applicants request that the Commission permit
the Exempt Companies to continue such transactions without compliance with the
provisions of Section 13(b) and the rules and regulations thereunder.


                                     -92-
<PAGE>

          The Commission has previously granted affiliates of registered holding
companies authority to provide goods and services to existing and future EWGs
(i.e., as defined under Section 32 of the Act), QFs (i.e., which meet the
requirements of PURPA and the FERC's regulations thereunder), and FUCOs (i.e.,
as defined under Section 33), without compliance with Section 13 and the rules
and regulations thereunder, that fall within one of the following categories:

          1)   the project is a FUCO or an EWG that derives no part of its
               income, directly or indirectly, from the generation,
               transmission, or distribution of electric energy for sale within
               the United States;

          2)   the project is an EWG that sells electricity at market-based
               rates which have been approved by the FERC or other appropriate
               state public utility commission, provided that the purchaser is
               not an Excepted company; (66)

          3)   the project is a QF that sells electricity exclusively at rates
               negotiated at arm's length to one or more industrial or
               commercial customers purchasing such electricity for their use
               and not for resale, or to an electric utility company other than
               an Excepted Company; or

          4)   the power project is an EWG or a QF that sells electricity at
               rates based upon its costs of service, as approved by FERC or any
               state public utility commission having jurisdiction, provided
               that the purchaser is not an Excepted Company.

Entergy Corporation, HCAR No. 26322 (June 30, 1995). (67)

          In the Entergy order, the Commission granted Entergy Enterprises, a
wholly-owned subsidiary of Entergy, authority to provide consulting services to
associate companies, including EWGs, FUCOs, and QFs, and operations and
management services, either directly, or through newly-established subsidiaries
of Entergy or Entergy Enterprises, to associate companies, including EWGs,
FUCOs, or QFs, without complying with the provisions of Section 13(b) and the
rules and regulations thereunder.




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

(66) An Excepted Company was defined as any subsidiary whose activities and 
operations were primarily related to the domestic sale of electric energy at 
retail or at wholesale to affiliates or providing goods and services to such 
affiliates.

(67) See also, General Public Utilities Corporation, HCAR No. 26307 (June 
14, 1995) and The Southern Company, HCAR No. 26212 (Dec. 30, 1994).


                                     -93-
<PAGE>

          Also, in CINergy Corp., Release No. 35-26376 (September 21, 1995), the
Commission authorized CINergy and CINergy Investments, a wholly-owned subsidiary
of CINergy, to acquire securities of new special purpose subsidiaries ("NSPS")
and to make additional investments in existing special purpose subsidiaries
("ESPS").  ESPS and NSPS acquire, own or hold securities of, and provide
services to, FUCOs or EWGs.  The Commission also authorized ESPS and NSPS and
CINergy Services to provide administrative, management and support services to
other ESPS and NSPS and their subsidiaries without complying with the provisions
of Section 13(b) and the rules and regulations thereunder.  See also General
Public Utilities Corp., Release No. 35-26457 (January 18, 1996) (pending
completion of the record, the Commission reserved jurisdiction over whether
subsidiaries formed to directly or indirectly acquire the securities of EWGs and
FUCOs ("Subsidiary Companies") could sell goods and services to associate
companies without complying with Section 13(b) and the rules and regulations
thereunder); Northeast Utilities, HCAR No. 26623 (December 12, 1996); New
England Electric Systems, HCAR No. 26504 (April 15, 1996)(granting requested
Section 13(b) exception).

          The Applicants request that the Commission permit the Exempt Companies
to provide services or sell goods to qualifying cogeneration facilities under
PURPA, EWGs under Section 32 of the Act, and FUCOs under Section 33 of the Act,
described in clauses 1, 2, 3, or 4 above, to the same extent permitted by the
Commission in the above-cited orders.

     4.   UE

          As previously discussed, following consummation of the Transaction, UE
will continue to perform engineering, development, design, construction, and
other related services, as a subsidiary of NC Enterprises.  UE will engage in
transactions with affiliated companies, as well as non-affiliated companies, on
the following bases:

          a.   SERVICES PROVIDED BY UE TO UTILITY ASSOCIATE
               COMPANIES.

     There are two methods by which UE may provide engineering, procurement,
construction and related services to utility associate companies.  UE may
contract directly with NC Services, which will then provide the services to the
utility associate companies.  Transactions between NC Services, as well as
between NC Services and the utility affiliates, will be provided in accordance
with Rules 90 and 91.  UE may also, from time to time, provide engineering,
procurement and construction services directly to certain utility associate
companies pursuant to contracts with the specific utility.  All such
transactions will be conducted in accordance with Rules 90 and 91.


                                     -94-
<PAGE>

          b.   SERVICES PROVIDED BY UE, OR JOINT VENTURES INVOLVING
               UE, TO NON-UTILITY ASSOCIATE COMPANIES.

          Consistent with the discussion above, it is contemplated that any
transactions by UE with non-utility associate companies will be conducted as
provided in Rules 87, 90, and 91 except to the extent that transactions on some
other basis are authorized by the Act or the Commission.  No services will be
provided by UE at market-based rates to entities or associated companies which
sell electricity to PSCo, SPS, or Cheyenne unless authorized by the Act or the
Commission.

     5.   SPECIFIC REQUESTS FOR EXEMPTIONS FROM SECTION 13

          Other than transactions between associate companies and qualifying
generation facilities under PURPA, EWG's under Section 32 of the Act, and FUCO's
under Section 33 of the Act, or those otherwise permitted by Commission rule,
there are no transactions for which NCE seeks an exemption from the
applicability of the "at cost" requirements under Section 13 except as follows:

          a.   QPS expects to be hired to provide operations and maintenance
services to the Phillips cogeneration plant to be built in Borger, Texas. 
Quixx, in partnership with LS Power, will own this QF.  The steam host will be
Phillips petroleum and the power will be sold pursuant to a power sale agreement
with SPS.  Quixx and LS power were awarded this project as a result of a bidding
process supervised by an independent bid examiner pursuant to guidelines set out
by the PUCT.  The Quixx/LS Power bid was deemed to be the most economic manner
for SPS to satisfy its anticipated power needs over the next few years.  The
power purchase contract will be at the rates set forth in the Quixx/LS Power
bid.  QPS will act as the operator on behalf of the partnership at a market-
based rate.  In addition, UE will be retained by the partnership to engineer and
construct the facility on the basis of a fixed price contract that was the basis
for the bid ultimately accepted by SPS.  Except for the fact that the power
under this project will be supplied to a system utility, this project would
otherwise fit under the exemption from Section 13 for services supplied to QFs,
EWGs and FUCOs.  For the same reasons that that exemption is appropriate,
deviation from Section 13 is appropriate in this project as well.

          The process that resulted in this Project was pursuant to state rules
and Quixx/LS Power were chosen on the basis of supplying the power to the
utility at the most favorable price of all the bidders.  Because the power sales
are based on a bid price pursuant to the state sanctioned process, there is no
potential for abuse of the rate paying public in permitting the transaction to
proceed outside of Section 13.  The price at which QPS will supply services will
not in any way effect the price that the power will be sold to the utility.  The
price that UE will receive to construct the plant will similarly not affect the
cost of electricity to SPS because it is a fixed price contract to provide a
turnkey plant to the owners.  Accordingly, none of the reasons underlying the
prohibitions in Section 13 are present in this situation and, in light of the
special circumstances


                                     -95-
<PAGE>

surrounding this project, an exemption pursuant to Section 13(b) should be 
granted.

          An exemption is further appropriate here because this project has been
in process for the last two years and all the bids were based on this structure
prior to becoming a registered holding company under the Act.  Since no
ratepayer interest will be affected by the transactions, it would be
unnecessarily burdensome to the project to have to fashion the project in
another way.

Item 4.  REGULATORY APPROVALS

          Set forth below is a summary of the regulatory approvals that NCE has
obtained or expects to obtain in connection with the Transaction.

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 DOJ and FTC and specified HSR Act
waiting period requirements have been satisfied.  The HSR Act application was
filed on August 22, 1996.  The applicable thirty-day waiting period expired
September 21, 1996. 

          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, Applicant believes that the Transaction will not violate
Federal antitrust laws.  If the Transaction is not consummated within twelve
months after the expiration or earlier termination of the initial HSR Act
waiting period, PSCo and SPS would be required to submit new information to the
Antitrust Division and the FTC, and a new HSR Act waiting period would have to
expire or be earlier terminated before the Transaction could be consummated.

B.   FEDERAL POWER ACT

          Section 203 of the Federal Power Act of 1935, as amended, provides
that no public utility shall sell or otherwise dispose of its jurisdictional
facilities or directly or indirectly merge or consolidate such facilities with
those of any other person or acquire any security of any other public utility,
without first having obtained authorization from the FERC.  PSCo and SPS
submitted a joint application for approval of the Transaction to the FERC on
November 9, 1995 (filed as Exhibit D-1.1).  PSCo and SPS reached a non-unanimous
agreement with the FERC Trial Staff and various intervenors.  (FERC Trial Staff
was not a signatory to the Settlement Agreement, but submitted supporting
comments.)  Hearings before a Presiding Administrative Law Judge ("ALJ") to
address the concerns of the one active party that did not sign the Settlement
Agreement were concluded on September 27, 1996.  On December 3, 1996, the ALJ
issued Certification of Contested Settlement Agreement (filed as Exhibit D-1.6
hereto).  In June 1995, FERC set for hearing limited issues in the


                                     -96-
<PAGE>

proceeding regarding (1) the scope of Applicants' hold harmless provision and 
(2) the effect of the merger on competition.  On August 30, 1996, SPS and 
PSCo filed a joint Settlement Agreement which resolved all issues in the 
proceeding raised by the many parties except those raised by the Colorado 
Association of Municipal Utilities ("CAMU").  The FERC Staff supported the 
Settlement Agreement. Hearings on CAMU's issues were held in September, 1996.

          In his certification, the ALJ concluded that the Settlement Agreement
should be certified to the FERC, without an initial decision, because no genuine
issues of disputed material fact were raised by CAMU.  The ALJ decided that the
areas of concern raised by CAMU are either premature, legally invalid,
adequately addressed by the Settlement Agreement, or relate to matters of policy
which the FERC may decide through application of its own expertise.  The ALJ
determined that the record is sufficient for the FERC to make a reasoned
determination of the Applicants' merger application.

          The ALJ concluded that CAMU's concerns regarding the hold-harmless
provision are either premature, beyond the scope of these proceedings, or
adequately addressed by the Settlement Agreement.  The ALJ also concluded that
the Applicants and Staff have shown that the merger is not anti-competitive,
and, in fact, may be pro-competitive.  Because CAMU did not demonstrate that any
anti-competitive effects will result from the merger, CAMU failed to offer any
genuine disputed issues of material fact for the ALJ to decide.  Subsequently,
CAMU withdrew its opposition to the merger, and on March 12, 1997, the FERC
issued its order approving the Transaction in accordance with the settlement.  A
copy of the FERC order is filed herewith as Exhibit D-1.7.

C.   STATE PUBLIC UTILITY REGULATION

          Colorado:  PSCo is subject to the CPUC.  Pursuant to Rule 55 of the
CPUC's Rules of Practice and Procedure, PSCo filed an application with the CPUC
requesting approval of the Merger Agreement on November 9, 1995.  The
application is required to demonstrate, among other things, that the approval
sought is not contrary to the public interest.  In addition, the CPUC considered
the rate making treatment associated with the Transaction.  PSCo also requested
that the CPUC also indicate that it does not object to the retention of PSCO's
and Cheyenne's Gas System in the NCE structure.  On August 23, 1996, the CPUC
issued an oral decision approving the merger.  This order was subsequently
confirmed in a decision issued on November 29, 1996, which is included as
Exhibit D-2.3.1, and in a decision on rehearing issued on January 15, 1997,
which is included as Exhibit D-2.3.2.

          Wyoming:  Cheyenne is subject to the jurisdiction of the WPSC. 
Pursuant to Section 37-1-104 of the Wyoming Revised Statutes, any reorganization
of a public utility requires prior approval of the WPSC.  The statute defines
reorganization as a transaction which results in a change in the ownership of a
majority of the voting capital stock of a public utility and precludes the WPSC
from


                                     -97-
<PAGE>

approving any reorganization that adversely affects the utility's ability to 
serve the public.  Pursuant to Section 209 of the WPSC's Rules of Practice 
and Procedure, Cheyenne filed an application for approval of the applicable 
portions of the Merger Agreement on November 9, 1995 (filed as Exhibit 
D-3.1). In addition, the WPSC considered the rate making treatment associated 
with the Transaction.  Cheyenne also requested that the WPSC also indicate 
that it does not object to the retention of Cheyenne's Gas System in the NCE 
structure. Ultimately, Cheyenne and the Consumer Advocate Staff of the WPSC 
entered into a stipulation and agreement resolving all issues.  On May 30, 
1996, the WPSC held a hearing on Cheyenne's application, and at the end of it 
issued a bench decision approving the application.  The WPSC subsequently 
confirmed the bench decision in a written order issued on August 16, 1996, 
which is included as Exhibit D-3.2.  The stipulation and agreement is 
attached to that order.

          New Mexico:  SPS is subject to the jurisdiction of the NMPUC. 
Pursuant to the New Mexico Public Utility Act and the NMPUC's Rules of Practice
and Procedure, SPS filed an application with the NMPUC requesting approval of
the Merger Agreement on November 9, 1995 (filed as Exhibit D-4.1).  The NMPUC
will approve the consummation of the Transaction if it finds that they are not
unlawful or inconsistent with the public interest and will not interfere with
the provision by SPS of reasonable and proper utility service at fair, just and
reasonable rates.  In addition, the NMPUC will consider the rate making
treatment associated with the Transaction.  Hearings were concluded on
August 22, 1996.  Though no settlement was reached, no party opposed the merger.
On November 15, 1996, a hearing examiner filed a recommended decision (included
as Exhibit D-4.2) that the merger is in the public interest if certain
conditions are met and SPS has substantially agreed to many of these conditions.
On January 28, 1997, the NMPUC issued an order approving the Transaction.  The
order is filed herewith as Exhibit D-4.3.

          Texas:  While SPS is not required under Texas law to obtain the
approval of the PUCT to merge with PSCo, SPS must report the Transaction to the
PUCT under Section 1.251 of the Public Utility Regulatory Act of 1995.  SPS
submitted such report to the PUCT on November 9, 1995 and requested that the
transaction be found to be in the public interest (filed as Exhibit D-5.1).  A
finding that the Transaction is not in the public interest does not prohibit the
consummation of the SPS Merger.  However, if the PUCT makes such a finding it is
required to take the effect of the merger into consideration in future
ratemaking proceedings and adjust the effect of the Transaction to the extent it
unreasonably affects rates or services.  Rate treatment resulting from a finding
that the Transaction was not in the public interest could materially and
adversely affect SPS.  SPS reached a non-unanimous agreement of the merger with
nine of ten intervenors including the PUCT staff.  The settlement provides for
the resolution of all outstanding issues, including a finding of the merger
being consistent with the public interest and commencement of the regulatory
plan, as modified by the settlement.  The settlement was submitted to the PUC,
and hearings were concluded on August 14, 1996.  On November 4, 1996, an
Administrative Law Judge of the PUCT issued a


                                     -98-
<PAGE>

Proposal for Decision and a Proposed Order finding that the PUCT should 
approve the merger with the conditions agreed to in the settlement.  That 
order was revised on December 5, 1996.  The Proposed Order and revisions 
thereto are included as Exhibits D-5.2.1 (with the settlement attached 
thereto) and D-5.2.2.

          On February 14, 1997, the PUCT issued an order finding the merger to
be in the public interest.  This order does, however, contain a provision that
allows 15 days from the date of the last Federal or state regulatory approval
for intervenors to seek to reopen the proceeding in Texas if they can
demonstrate that "one or more of the orders issued by other regulatory
authorities materially and detrimentally denies SPS' Texas retail ratepayers the
benefits of the NUS that are incorporated in this Order. . . ."  (Texas order at
51.)  Unless such a request is made within the 15 days, the Texas order of the
PUCT will automatically become effective.  (Id.)  If there is an attempt to
reopen the proceeding, any additional inquiry will be limited to the effect, if
any, of the impact of the later regulatory orders.  (Id.)

          All state filings of public interest and approvals, and all federal
approvals, other than that of this Commission, have been obtained.  None of
these findings or approvals in the opinion of NCE have materially and
detrimentally denied the SPS Texas retail ratepayers of the benefit of the NUS
that are incorporated in the Texas order.  Accordingly, Applicant is prepared to
close the Transaction upon the receipt of the Commission's order.  Although it
is possible that an intervenor could seek to reopen the Texas proceedings, the
Commission should issue its order on the basis that the existing order of the
PUCT is final.  Should the Commission not so conclude, the same rule should be
applied here as was applied in Entergy, Inc., 55 SEC Docket 2035, 2044 n. 68,
and 2051 (Commission Order approving merger conditioned on the receipt by the
Commission of a final order from the PUCT approving the transaction).  A copy of
the PUCT's order is filed herewith as Exhibit D-5.3.

          Kansas:  SPS is subject to the jurisdiction of the KCC, pursuant to
the Kansas Public Utility Act.  On November 9, 1995, SPS filed an application
with the KCC requesting authority for the issuance of common stock by SPS to NCE
pursuant to the Merger Agreement (filed as Exhibit D-6.1).  The application is
required to describe the purposes for which the common stock is to be issued and
state that such issuance is necessary and required and will be sold for such
purposes.  The KCC issued its order granting the requested authority to SPS on
November 28, 1995 (included as Exhibit D-6.2).  Subsequently, on December 3,
1996, the KCC issued an order (included as Exhibit D-6.3) approving a rate
jurisdictional agreement among NCE, SPS, and the KCC Staff in connection with
the merger.

          NCE is also be subject to the KCC pursuant to the Kansas Holding
Companies Act ("KHCA").  The KHCA states that no foreign holding company shall
acquire control of a Kansas public utility without first entering into an
agreement to keep the KCC fully informed as to transactions between the utility
and the holding 


                                     -99-
<PAGE>

company and to submit to the jurisdiction of the KCC insofar as
such transactions affect the retail rates or charges to be made by the utility. 
On November 12, 1996, NCE and SPS entered into a Rate Effect Agreement with the
Director of the KCC in which NCE and SPS agreed that NCE will keep the KCC fully
informed as to the transactions between SPS and NCE which affect the rates of
SPS's Kansas retail customers.  The KCC approved the agreement on December 3,
1996.

          Oklahoma:  SPS is subject to the jurisdiction of the OCC.  However, no
approval or authorization of any Oklahoma public regulatory body, including the
OCC, of the Merger Agreement is required.

Item 5.  PROCEDURE

          The Commission published a notice of the Transaction under Rule 23
dated March 22, 1996.  Petitions to intervene were filed by three parties.  As
of the date hereof, two of the intervenors have withdrawn their petitions and
the third has filed a notice of non-opposition conditioned on approval of the
Settlement Agreement entered into in the FERC proceedings which has now
occurred.  Therefore, there are no intervenors opposing the Transaction in this
proceeding.

          NCE requests that the Commission's order be issued as soon as the
rules allow.  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.

matter.

                                 INTRODUCTION

     New Century Services ("NCS") will provide Public Service Company of 
Colorado ("PSCo"), Southwestern Public Service Company ("SPS"), Cheyenne 
Light, Fuel and Power Company ("Cheyenne") (collectively referred to as the 
"Operating Companies"), and other affiliates of the New Century Energies 
system with a variety of administrative, management, engineering, 
construction, and support services.  NCS will be subject to the rules and 
regulations of the Securities and Exchange Commission ("SEC") pursuant to the 
Public Utility Holding Company Act of 1935, as amended ("PUCHA"), and, in 
particular, Section 13 thereof.

     NCS will provide such services in accordance with service agreements 
which will be entered into with the Operating Companies and affiliates.  The 
service agreements will be administered in accordance with PUHCA and the 
SEC's regulations thereunder.  NCS will establish a work order system,  which 
utilizes work orders (referred to as "Service IDs"),  for the purpose of 
charging costs to the appropriate Operating Company and/or affiliates.   The 
use of Service IDs will allow NCS to supply accounting records and 
information to the Operating Companies and affiliates in enough detail to 
allow them to record and report their costs in accordance with the Federal 
Energy Regulatory Commission ("FERC") Uniform System of Accounts.

     The major objective of NCS is to consolidate support services in order 
to provide those services to the Operating Companies and affiliates of New 
Century Energies, Inc. ("NCE") more effectively and efficiently than each 
company could provide for itself.  To achieve this end, NCS will strive to 
become cost competitive and focus on providing value added services to all 
customers.  As part of this effort, NCS will use Benchmarking to 

1
<PAGE>

gauge the cost effectiveness and competitiveness of its operations and strive 
to continuously improve processes.  The service providers of NCS will be 
given 18 months from the effective date of the merger to become cost 
competitive.  If, after that period, the NCS customer believes its needs and 
requirements are not being satisfied, the customer will have a choice to 
look elsewhere on a service-by-service basis.  This includes looking at 
external sources.  However, it will be up to the Operating Company and/or 
affiliate that desires to pursue alternate sources, to prepare a business 
case establishing evidence that it will be more cost effective and efficient 
to use an external source.

ACCOUNTING PROCEDURES

     NCS will utilize Service IDs for the purpose of allocating costs to the 
appropriate Operating Company and/or affiliates.  A Service ID will be 
established and recorded with each NCS transaction as it is the Service ID 
which dictates how the costs are to be allocated between the Operating 
Companies and affiliates.  In summary, NCS will use the following six types 
of Service IDs:

     DIRECT SERVICE ID -  A Direct Service ID will be used when the service
     being provided is performed for a specific Operating Company or affiliate.
     The Operating Company or affiliate specified will be charged 100% of the
     costs.  For example, if NCS Tax Services is providing tax services such as
     tax return preparation or tax advisory services directly to SPS, 100% of
     the costs to provide those services will be billed to SPS using the 100%
     direct charge Service ID for Tax Services.

     DISTRIBUTED SERVICE ID - A Distributed Service ID will be used for
     specific services that will be distributed to two or more Operating
     Companies or affiliates.  An 

2
<PAGE>

     example of when to use a Distributed Service ID is if  Tax Services 
     prepares the consolidated federal income tax return for all NCS 
     companies.  The NCS costs to prepare the tax return will be 
     distributed to all of the companies using a Distributed Service ID which
     will specify the appropriate allocation factor.  Please refer to
     Attachment 1 which defines the allocation factors that may be used.

     INDIRECT SERVICE ID - An Indirect Service ID will be used to charge costs
     which are of a general nature and cannot be specifically identified to an
     Operating Company or affiliate.  The allocation to the Operating Companies
     and affiliates will be based on the allocation factors described in the
     NCS Service Agreements.  For example, an Indirect Service ID will be used
     for those costs of Tax Services that cannot be specifically identified to
     a particular task or company, such as attending departmental meetings or
     classes and performing administrative type tasks.  The Indirect Service ID
     for Tax Services will be used to allocate these general costs to all the
     Operating Companies and affiliates that benefit from services provided by
     the Tax Services Department.

     LABOR OVERHEAD SERVICE ID - The Labor Overhead Service ID will be used to
     charge overhead costs associated with labor, such as pension and benefits,
     workers compensation, and payroll taxes.  The Labor Overhead costs will be
     charged to the Operating Companies and affiliates based on the NCS labor
     costs that were charged.

     A&G OVERHEAD SERVICE ID - The A&G Overhead Service ID will include, but
     not be limited to,  property insurance, rent, depreciation, property
     taxes, etc.  These 

3
<PAGE>

     overhead costs will also be charged to the Operating Companies and 
     affiliates based on  the NCS labor costs that were charged.

     CONSTRUCTION OVERHEAD SERVICE ID - The Construction Overhead Service ID
     will be used to accumulate overhead costs to be charged to capital
     projects on the books of the Operating Companies and/or affiliates, such
     as engineering and supervision overheads, and continuing property record
     overheads.

     The Service ID, along with certain segments of NCS's account number, will
provide the detailed information necessary to bill the Operating Companies and
affiliates.  Certain segments of the account number used to record the
transaction will provide information such as the NCS unit performing the work,
the Operating Company and/or affiliate being charged and the type of activity
being performed.

NCS POLICIES AND PROCEDURES

SERVICE REQUEST AND APPROVAL PROCEDURES

     Each functional department of  NCS will be assigned a minimum of one
Direct and one Indirect Service ID by NCS Accounting.  The Direct Service ID
will be used when performing specific routine services for one Operating
Company or affiliate.  The SEC requires that, whenever feasible, NCS costs
should be directly charged to the Operating Companies or affiliates.  These
services will be reviewed and agreed upon with the Operating Companies and
affiliates at the beginning of each calendar year.  Examples of routine
services include the monthly closing of the financial accounting and budgeting
systems, preparing financial reports, and preparing a financial forecast.  An
Indirect Service ID will  be used to allocate those costs that cannot be
directly assigned.  Again, 

4
<PAGE>

these types of costs, which will be incurred by NCS, will be reviewed and 
approved by the affected Operating Companies and affiliates at the beginning 
of each year.

     Distributed Service Ids will be assigned on a case-by-case basis depending
upon the special service or project provided by NCS.

     All activities performed by NCS for the Operating Companies and affiliates
must have a completed Service Request form.  For routine services provided and
indirect costs charged, a Service Request form will be completed at the
beginning of each year.  For the  performance of non-routine, or special
services, a Service Request form will be initiated by the Operating Companies
and affiliates or by NCS.  Examples of non-routine, or special services include
requests to prepare rate case testimony, special securities financings and
special studies or analyses.  The method of cost allocation will be determined
on a case-by-case basis consistent with the nature of the work performed.
Approvals are required by the organization that is requesting the work, the NCS
service provider and the Service ID Administrator in the Accounting
Organization.

SERVICE REQUEST GUIDELINES

          A request for a new Service ID may be appropriate when a new 
service or project is identified.  However, the cost of the new service or 
project may be able to be captured in an existing Service ID.  The following 
guidelines should be used in determining when a new Service ID is appropriate.

     1.   No existing Service ID uses the billing method  that is most 
          appropriate for the new service or project.

     2.   No existing Service ID distributes costs to the desired Operating 
          Companies and affiliates for this new service or project

     3.   One or two above, PLUS the total estimated annual cost of the new 
          service or project is greater than $25,000.

     4.   There is a specific regulatory requirement to allocate costs in a 
          specific manner regardless of amount for the new service or project

MONITORING AND CONTROL

     The NCS Service ID Administrator in NCS Accounting is responsible for 
reviewing, monitoring and maintaining the Service ID system.  The 
Administrator also authorizes new Service IDs  and ensures that the allocation 
factors are proper, accurate and kept up to date including ensuring that the 
revision process is in accordance with the SEC regulations. Additionally, the 
Service ID Administrator will be responsible for coordinating the monthly 
billing process as described in the Billing Policies and Procedures.

SERVICE ID ALLOCATION FACTORS UPDATE AND REVISIONS

     The NCS Service ID Administrator in NCS Accounting will have the primary 
responsibility for ensuring that the Service ID allocation factors are 
proper, accurate and kept up to date.  All allocation factors utilized must 
be approved by the SEC.

     To the greatest extent possible, the allocation factors will be based on 
cost drivers specifically applicable to the service being provided.  NCS 
Accounting will decide on the appropriate allocation factors  for the 
indirect Service ID's. NCS Accounting, the customer and the service provider 
together will decide on the proper allocation factor(s) for the distributed 
SID's.

     The NCS Service ID Administrator  will be responsible for evaluating new 
allocation methodologies and determining if SEC approval is required.  The 
NCS Administrator will coordinate SEC approval efforts, if necessary,  with 
the Legal Department.

TIME REPORTING

     Every employee of New Century Services, Inc. (NCS) must keep track of 
their time in order to bill the Operating Companies and affiliates 
accurately. The following guidelines are provided to ensure accurate and 
efficient time keeping.

      -    A customized time tracking form for your area can be obtained from 
           the NCS Accounting Service ID Administrator.
      -    Employees should keep track of their time in one hour increments. *
      -    It is recommended that time be entered by the time keeper daily 
           and at the very minimum on a weekly basis.  In either case, time 
           must be entered by the payroll cut off dates.


9

<PAGE>

      -    The employee's manager will approve the time report weekly. Each 
           weekly time sheet will be signed by the manager.

*Please note that if you are repeatedly spending less than an hour on a 
particular activity for the week, and total time spent for the week will be 
one hour or more, then record time spent on that activity for the week rather 
than by the day.  For example, if you work 20 minutes per day for one week on 
a special project for PSCo, then you would record 2 hours for that activity 
for that week.

BILLING AND REVIEW

     Each Operating Company and affiliate will receive a monthly bill 
detailing the work performed by NCS. Each bill or invoice will contain the 
following information:

      -    Company

      -    Type of service provided by function and activity (i.e., accounting,
           close the books)

      -    Direct Charges

      -    Indirect Charges

      -    Account number charged

      -    Service ID number

      -    Amount

     Detailed information such as time sheets, unit being charged and the 
unit performing the work will be available upon request.

     The Service ID Administrator in NCS Accounting is responsible for
establishing and administering the NCS Service IDs and billing policies and
procedures.   Please refer


10

<PAGE>


to the "Service ID Allocation Factors Update and Revision Procedures" for 
additional detail.

      After the Service IDs are processed and transactions are posted to NCS, 
initial billings are generated.  The Service ID Administrator reviews the 
initial billings for errors at this time.   The Service ID Administrator will 
also verify that the Service ID 's have the correct allocators.  Any material 
discrepancies identified  will be corrected  prior to the generation of the 
final financial statements.  After the final financial statements are 
generated, the Service ID Administrator will reconcile the billings to the 
NCS general ledger.   If an error is found after the final statements are 
generated, the correction will be made the following month.

     Upon receipt of the billing, budget analysts for the Operating Companies 
and affiliates, with assistance from the NCS  Service ID Administrator, will 
review and reconcile the billing.  Any discrepancies found at this time are 
discussed with the Service ID Administrator and corrections are made to the 
subsequent month's bill.

DISPUTE RESOLUTION PROCEDURE

     In the event there is a dispute between the Operating Company and/or 
affiliate and a NCS service provider regarding a billing methodology and/or 
amount, representatives from the Operating Company and/or affiliate receiving 
service and the NCS service provider along with the NCS Service ID 
Administrator will meet to discuss the issues.  Depending upon the magnitude 
of the dispute, the Business Controls Coordinator may also assist in the 
dispute resolution discussions.  If a resolution cannot be reached among 
these parties, the issue will be referred to each parties' executive 
management for final resolution.

INTERNAL AUDIT CONTROL

     NCS' Internal Audit department will conduct periodic reviews of  its 
operating methods as well as computer systems to ensure that the services 
provided are authorized, documented and accurately recorded in NCS'  books 
and records.  The Internal Audit department will also conduct reviews of the 
Service ID cost allocation methods to ensure that such methods comply with 
those approved by the SEC.

     The Internal Audit Manager establishes audits to be performed, and how 
the audits are to be carried out, with the NCE Internal Audit Committee. For 
normal subordinate-superior relationships, and to ensure that the Internal 
Audit department's review is objective and its findings are adequately 
addressed, the manager of the Internal Audit Department will report directly 
to the Chairman and CEO of NCE.

BUDGETING

     After the transition phase (approximately 6 months after the effective
date of the merger), budgeting for NCS will be a joint effort between NCS and
the Operating Companies and affiliates.  All managers of  NCS will be
responsible for preparing annual budgets in order to provide budget information
to the Operating Companies and affiliates.  Services to be provided to the
Operating Companies and affiliates will be identified and agreed upon  and cost
estimates will be prepared annually.  These estimates will be approved by the
Operating Companies and affiliates as previously noted.   Budget variance
reports will be generated each month and NCS will have the primary
responsibility for analyzing and explaining cost variances.  NCS will be
accountable for costs for services

will jointly be accountable for the cost of discretionary services.

EVALUATION AND MEASUREMENT

                                       
     In order to encourage NCS to operate efficiently and cost effectively, 
and provide high quality service, NCS will initiate bench marking activities 
and a customer review process.  The process will support a customer-oriented 
service philosophy by measuring success based upon customer satisfaction.   
It will allow for customer input into the volume and value of the products 
and services provided by NCS.  Comprehensive reviews will be part of the 
annual budget development process.  The initial vehicle used for this process 
will be the annual completion of the Service Request Agreements between the 
service provider and the customer.  This agreement will describe the product 
or service provided, the level of service expected and the expected costs to 
provide that service or product.

     In addition to the review process with customers, NCS will perform bench 
marking activities to continue to improve the effectiveness of services 
offered to the Operating Companies and affiliates and to ensure that the 
services offered are cost competitive.

Dear Sirs:

            I refer to the Form U-1 Application-Declaration, as amended (the

            The Application seeks authorization and approval for a number of 
transactions, including:

     (i)    the acquisition by NCE of all of the issued and outstanding common

            Service Company ("SPS") by means of the merger of SPS and SPS 
            Merger Corp., of Cheyenne Light, Fuel and Power Company ("Cheyenne")
            by the declaration of a dividend of all the outstanding common 
            stock of Cheyenne by PSCo to NCE, of PS Colorado Credit Corporation

     (iii)  the establishment by NCE of a new subsidiary, NC Enterprises,
            Inc. ("NC Enterprises"), to serve as a holding company for certain
            of the NCE system's non-utility interests, and the acquisition by NC
            Enterprises of the stock and other voting equity of such non-utility
            interests including (a) certain subsidiaries of PSCo by the

          j.   No act or event other than as described herein shall have
               occurred subsequent to the date hereof which would change the
               opinions expressed above.

          Based upon the foregoing, and subject to the assumptions and
conditions set forth herein, and having regard to legal considerations which I
deem relevant, I am of the opinion that, in the event that the proposed
Transactions are consummated in accordance with the Application:


          1.   The laws of the States of Colorado and Wyoming applicable to the
               proposed Transactions will have been complied with.

          2.   Each of NCE, NC Services, and NC Enterprises is validly
               organized and duly existing under the laws of the State of
               Delaware; PSCo is validly organized and duly existing under the
               laws of the State of Colorado; following the filing of an
               appropriate instrument of incorporation, PSCo Merger Corp. is
               validly organized and duly existing under the laws of the State
               of Colorado; Cheyenne is validly organized and duly existing
               under the laws of the State of Wyoming; and each non-utility
               company whose securities will be acquired by NCE or NC
               Enterprises from PSCo or its subsidiaries is validly organized
               and duly existing under the laws of the respective state of
               incorporation.
     
          3.   The shares of NCE Common Stock to be issued in connection with
               the proposed Transactions will be validly issued, fully paid and
               nonassessable, and the holders thereof will be entitled to the
               rights and privileges appertaining thereto set forth in the
               Restated Certificate of Incorporation of NCE.  The shares of
               common stock of PSCo to be issued to NCE in connection with the
               merger of PSCo Merger Corp. with and into PSCo will be validly
               issued, fully paid and nonassessable, and NCE, as the holder
               thereof, will be entitled to the rights and privileges
               appertaining thereto set forth in the Certificate of
               Incorporation of PSCo.  The shares of common stock of NC
               Enterprises held by NCE and the shares of common stock of NC
               Services to be acquired by NCE are or will be validly issued,

               will be entitled to the rights and privileges appertaining
               thereto set forth in the instrument of incorporation of each of
               NC Enterprises and NC Services.  The shares of common stock to
               be acquired by NC Enterprises from PSCo or its subsidiaries as a
               holding company for certain non-utility subsidiary companies of
               the NCE System will be 


                                        4
<PAGE>


               validly issued, fully paid and nonassessable, and NC Enterprises
               or NCE, as the case may be, as the respective holders thereof 
               will be entitled to the rights and privileges appertaining 
               thereto set forth in the respective charters and other governing
               documents of such companies.
     
          4.   NCE will legally acquire (a) the shares of common stock of PSCo
               that will be issued to NCE in connection with the merger of PSCo
               Merger Corp. with and into PSCo, (b) the shares of common stock
               of Cheyenne by means of a dividend by PSCo of all of the stock
               of Cheyenne to NCE, (c) the shares of stock of West Gas
               Interstate, Inc. and PSCCC by means of a dividend by PSCo of all
               of their stock to NCE, and (d) the shares of NC Services that
               will be issued to NCE in connection with the Transactions, as
               the case may be.  NCE has legally acquired the shares of common
               stock of NC Enterprises, and NC Enterprises will legally acquire
               the shares of stock of the subsidiary companies of PSCo or its
               subsidiaries for which it will serve as a holding company.
     
          5.   The consummation of the proposed Transactions will not violate
               the legal rights of the holders of any securities issued by NCE
               or PSCo or its subsidiaries.
     
          I have acted as counsel for NCE and PSCo in connection with the
Application and, accordingly, this opinion is limited to actions taken by NCE,
PSCo (and its subsidiaries prior to the Transactions), PSCo Merger Corp., NC
Services, and NC Enterprises in connection with the Transactions as described
in the Application.  With respect to compliance with all other applicable state
laws, the corporate proceedings of any other parties to the Transactions,
including the issuance, sale, or acquisition of securities by such parties, or
the absence of the violation of the legal rights of the holders of securities
of such parties, I refer to the opinion of Cahill Gordon & Reindel filed
concurrently herewith.

          I hereby consent to the use of this opinion as an exhibit to the
Application.


                                   Very truly yours,

     to comply with Section 13 of the Act and the Commission's rules thereunder;
     
      (iii)   the establishment by NCE of a new subsidiary, NC Enterprises, Inc.
     ("NC Enterprises"), to serve as a holding company for certain of the NCE

     stock by PSCo to NCE and a subsequent capital contribution by NCE to NC
     Enterprises and (b) all the subsidiaries of SPS through the sale by SPS of 
     all of their outstanding common stock to NC Enterprises in exchange for

     SPS in connection with the mergers described in clause (i) above;
     
 ((i) through (iv) collectively, the "Transactions").

          We have acted as special counsel for NCE and SPS in connection with
the Application and, as such counsel, we are familiar with the corporate
proceedings taken by NCE, SPS, SPS Merger Corp., NC Services and NC Enterprises
in connection with the Transactions as described in the Application.

and other documents as we have deemed necessary to examine as a basis for the
opinions hereinafter expressed.  In such examination we have assumed the
genuineness of all signatures and the authenticity of all documents submitted
to us as originals and the conformity with the originals of all documents
submitted to us as copies.  As to various questions of fact material to such
opinions we have, when relevant facts were not independently established,
relied upon certificates of officers of NCE, SPS, SPS Merger Corp., NC Services
and NC Enterprises and other appropriate persons and statements contained in
the Application and the exhibits thereto.

          k.   No act or event other than as described herein shall have

          l.   The consummation of the Transactions shall be conducted with our

<PAGE>

                               -5-

     to the Transactions in which we are not admitted to practice, as we may 
     deem appropriate.
     
          Based upon the foregoing, and subject to the assumptions and
conditions set forth herein, and having regard to legal considerations which we
deem relevant, we are of the opinion that, in the event that the proposed
Transactions are consummated in accordance with the Application:

          1.  The laws of the states of New Mexico, Texas and Kansas applicable 
     to the proposed Transactions will have been complied with.
     
          2.  Each of NCE, NC Services and NC Enterprises is validly organized 
     and duly existing under the laws of the State of Delaware; SPS is validly 
     organized and duly existing under the laws of the State of New Mexico; 
     following the filing of an appropriate instrument of incorporation, SPS 
     Merger Corp. will be validly organized and duly existing under the laws 
     of the State of New Mexico; and each non-utility company whose securities 
     will be acquired by NC Enterprises from SPS is validly organized and duly 
     existing under the laws of the respective state of incorporation.

          3.  The shares of NCE Common Stock to be issued in connection with the
     proposed Transactions will be validly issued, fully paid and nonassessable,
     and the holders thereof will be entitled to the rights and privileges 
     appertaining thereto set forth in the Restated Certificate of 
     Incorporation of NCE.  The shares of common stock of SPS to be issued to 
     NCE in connection with the merger of SPS Merger Corp. with and into SPS 
     will be validly issued, fully paid and nonassessable, and NCE, as the 
     holder thereof, entitled to the rights and privileges appertaining thereto 
     set forth in the Restated Articles of Incorporation of SPS.  The shares of 
     common stock of NC Enterprises and NC Services to be issued to NCE in 
     connection with the establishment of NC Enterprises and NC Services as 
     subsidiaries of NCE, respectively, will be validly issued, fully paid and 
     nonassessable, and NCE, as the holder thereof, will be entitled to the 
     rights and privileges appertaining thereto set forth in the instrument of 
     incorporation of each of NC Enterprises and NC Services.  The shares of 
     common stock to be acquired by NC Enterprises from SPS as a holding 
     company for certain non-utility subsidiary companies of the NCE system 
     will be validly issued, fully paid and nonassessable, and NC Enterprises, 
     as 

<PAGE>

                                  -6-

     the holder thereof, will be entitled to the rights and privileges 
     appertaining thereto set forth in the respective charters and other 
     governing documents of such companies.
     
          4.  NCE will legally acquire (a) the shares of common stock of SPS 
     that will be issued to NCE in connection with the merger of SPS Merger 
     Corp. with and into SPS, and (b) the shares of NC Enterprises and NC 
     Services that will be issued to NCE in connection with the Transactions.  
     NC Enterprises will legally acquire the shares of stock of the subsidiary 
     companies of SPS for which it will serve as a holding company.
     
          5.  The consummation of the proposed Transactions will not violate the
     legal rights of the holders of any securities issued by NCE, NC Services, 
     NC Enterprises or SPS or its subsidiaries.
     
          We have acted as special counsel for NCE and SPS in connection with
the Application and, accordingly, this opinion is limited to actions taken by
NCE, SPS (and its subsidiaries prior to the Transactions), SPS Merger Corp., NC
Services and NC Enterprises in connection with the Transactions as described in
the Application.  With respect to compliance with all other applicable state
laws, the corporate proceedings of any other parties to the Transactions,
including the issuance, sale or acquisition of securities by such parties, or
the absence of the violation of the legal rights of the holders of securities
of such parties, we refer to the opinion of William M. Dudley filed
concurrently herewith.

          We hereby consent to the use of this opinion as an exhibit to the
Application.

                                   Very truly yours,
