Agreement and Plan of Reorganization dated August 22, 1995, as amended December
8, 1995, providing for a business combination as peer firms involving PSCo and

SPS and Cheyenne Light, Fuel and Power Company. The Company also owns several
non-utility subsidiaries. The principal executive offices of the Company are
located at 1225 17th Street, Denver, Colorado 80202.

                                 USE OF PROCEEDS

     Unless otherwise indicated in an accompanying Prospectus Supplement, the
Company intends to use the net proceeds from the sale of the Common Stock for
general corporate purposes, including to retire debt and to make capital
contributions to its subsidiaries. If the Company uses any proceeds to make a
capital contribution to a subsidiary, such subsidiary will use such proceeds to
retire debt and for general corporate purposes.

                              PLAN OF DISTRIBUTION

     The Company may sell the Common Stock in any of three ways: (i) directly to
one or more purchasers; (ii) through agents; or (iii) through underwriters or
dealers. The Prospectus Supplement relating to each offering of Common Stock
will set forth the terms of the offering of such Common Stock, including the
name or names of any such agents, underwriters or dealers, the purchase price of
such Common Stock and the net proceeds to the Company from such sale, any
underwriting discounts and other items constituting underwriters' compensation,
the initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers. Any initial public offering price and any
discounts or concessions allowed or reallowed or paid to dealers may be changed
from time to time.

     If underwriters are used in any sale of Common Stock, such Common Stock
will be acquired by such underwriters for their own account and may be resold
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. Such Common Stock may be offered to the public either
through underwriting syndicates represented by managing underwriters or by
underwriters without a syndicate. Unless otherwise set forth in the Prospectus
Supplement relating to a sale of Common Stock, the obligations of any
underwriter or underwriters to purchase such Common Stock will be subject to
certain conditions precedent and such underwriter or underwriters will be
obligated to purchase all of such Common Stock if any shares are purchased,
except that, in certain cases involving a default by one or more underwriters,
less than all of such Common Stock may be purchased. Only underwriters named in
a Prospectus Supplement are deemed to be underwriters in connection with the
Common Stock offered thereby.

     If underwriters are used in any sale of Common Stock, the purchase
agreement in connection with such sale may provide for an option on the part of
the underwriters to purchase additional shares of such Common Stock within
thirty days of the execution of such purchase agreement, which option may be
exercised solely to cover overallotments. Any such overallotment option will be
disclosed in the Prospectus Supplement in connection with the Common Stock
offered thereby.



                                      -4-


     If an agent of the Company is used in any sale of Common Stock, such agent
will be named and any commission payable by the Company to such agent will be
set forth in the Prospectus Supplement relating to such Common Stock. Unless
otherwise indicated in the Prospectus Supplement, any such agent will be acting
on a best effort basis for the period of its appointment.

     The Common Stock offered hereby will be listed on the New York Stock
Exchange.

     Any underwriters, dealers or agents participating in the distribution of
the Securities may be deemed to be underwriters, and any discount or commissions
received by them on the sale or resale of Securities may be deemed to be
underwriting discounts and commissions, under the Securities Act of 1933, as
amended (the "Securities Act"). Agents, underwriters and dealers may be entitled
under agreements entered into with the Company to indemnification by the Company
against certain liabilities, including liabilities under the Securities Act.

business.

accordance with professional standards for a review of that information.
However, their separate reports thereon state that they did not audit and they

the degree of reliance on their reports on that information should be



                                      -5-


restricted in light of the limited nature of the review procedures applied. In
addition, the accountants are not subject to the liability provisions of Section
11 of the Securities Act of 1933 for their reports on the unaudited interim
financial information because those reports are not a "report" or a "part" of
the Registration Statement prepared or certified by the accountants within the

reviews of such information. As stated in their reports that are included in

and February 28, 1997 that are incorporated by reference herein, they did not
audit and they did not express an opinion on such interim financial information.
Accordingly, the degree of reliance of any of their reports on such information
should be restricted in light of the limited nature of the review procedures
applied. Deloitte & Touche are not subject to the liability provisions of
Section 11 of the Securities Act for any of their reports on such unaudited
interim financial information because those reports are not "reports" or a

Item 15.  Indemnification of Officers and Directors.

     Section 145 of the Delaware General Corporation Law (the "Delaware Act")
permits corporations organized thereunder to indemnify directors, officers,
employees and agents against liability under certain circumstances. The
Company's Restated Certificate of Incorporation (the "Company Charter") provides
for indemnification of directors, officers, employees and agents to the full
extent provided by the Delaware Act. The Company Charter states that the
indemnification provided therein shall not be deemed exclusive. The Company may
purchase and maintain insurance on behalf of itself and any director, officer,
employee or agent of the Company or another corporation, partnership, joint
venture, trust or other enterprise against any expense, liability or loss,
whether or not the Company would have the power to indemnify such person against
such expense, liability or loss under the Delaware Act. Pursuant to Section
145(g) of the Delaware Act and the Company Charter, the Company maintains
directors' and officers' liability insurance coverage. The Company may also
enter into an indemnity agreement with any director, officer, employee or agent
of the Company or another corporation, partnership, joint venture, trust or
other enterprise, as long as the provisions of the agreement are not
impermissible under applicable law.

     As permitted by Section 102(a) of the Delaware Act, the Company Charter
provides that no director shall be personally liable to the Company or its
shareholders for monetary damages for breach of fiduciary duty as a director,
except for liability: (i) for any breach of the directors' duty of loyalty to
the Company or its shareholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware Act (relating to certain unlawful distributions to
shareholders) or (iv) for any transaction from which the director derived an
improper personal benefit.

Item 17.  Undertakings.

     The undersigned registrant hereby undertakes:

1.   To file, during any period in which offers or sales are being made, a
     post-effective amendment to this Registration Statement:

     (a)  To include any prospectus required by Section 10(a)(3) of the
          Securities Act;

     (b)  To reflect in the prospectus any facts or events arising after the
          effective date of the Registration Statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the Registration Statement. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          a 20% change in the maximum aggregate offering price set forth in the
          "Calculation of Registration Fee" table in the effective Registration
          Statement; and

     (c)  To include any material information with respect to the plan of
          distribution not previously disclosed in the Registration Statement or
          any material change to such information in the Registration Statement.

     provided, however, that paragraphs 1(a) and 1(b) do not apply if the
     information required to be included in such post-effective amendment is
     contained in a periodic report filed by the Company pursuant to Section 13
     or Section 15(d) of the Exchange Act and incorporated herein by reference.

2.   That, for the purpose of determining any liability under the Securities
     Act, each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.

3.   To remove from registration by means of a post-effective amendment any of
     the securities being registered which remain unsold at the termination of
     the offering.

4.   That, for purposes of determining any liability under the Securities Act,
     each filing of an annual report pursuant to Section 13(a) or 15(d) of the
     Exchange Act that is incorporated by reference in the Registration
     Statement shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

5.   Insofar as indemnification for liabilities arising under the Securities Act
     may be permitted to directors, officers and controlling persons of the
     undersigned pursuant to the provisions described under Item 15 above, or
     otherwise, the undersigned have been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Securities Act and is, therefore, unenforceable.
     In the event that a claim for indemnification against such liabilities
     (other than the payment by the undersigned of expenses incurred or paid by
     a director, officer or controlling person of the undersigned in the
     successful defense of any action, suit or proceeding) is asserted by such
     director, officer or controlling person in connection with the securities
     being registered, the undersigned will, unless in the opinion of its
     counsel the matter has been settled by control-



                                      II-2


     ling precedent, submit to a court of appropriate jurisdiction the question
     of whether such indemnification by it is against public policy as expressed
     in the Securities Act and will be governed by the final adjudication of
     such issue.















                                      II-3
