   ITEM 5.     Other Events

   Public Service Company of Colorado, a Colorado corporation ("PSC"),
   Southwestern Public Service Company ("SPS"), a New Mexico corporation, and
   M-P New Co., (the "Company" or "Newco"), a newly formed Delaware
   corporation, have entered into an Agreement and Plan of Reorganization,
   dated August 22, 1995, (the "Merger  Agreement") providing for a business
   combination as peer firms involving PSC and SPS in a "merger of equals"
   transaction (the "Merger").  The Merger, which was unanimously approved by
   the Boards of Directors of the constituent companies, is expected to occur
   shortly after all of the conditions to the consummation of the Merger,
   including obtaining applicable regulatory approvals, are met or waived. 
   The regulatory approval process is expected to take approximately 12 to 16
   months.

   The Merger Agreement and the press release issued in connection therewith
   are filed  herewith as exhibits 2 and 99, and are incorporated by
   reference herein.  The description of the Merger Agreement set forth
   herein does not purport to be complete and is qualified in its entirety by
   the provisions of the Merger Agreement.

   As part of the Merger, the holding company of the combined enterprise will
   be registered under the Public Utility Holding Company Act of 1935, as
   amended ("1935 Act").  The Company, which will serve as the holding
   company, will be renamed at a later date and will be the parent company of
   both PSC and SPS.

   Under the terms of the Merger Agreement, New PSC will be merged with and
   into PSC and New SPS will be merged with and into SPS.  PSC and SPS shall
   be the surviving corporations  and shall continue their corporate
   existence under the laws of the State of Colorado and the State of New
   Mexico, respectively.  As a result of the mergers, both PSC and SPS  will
   become subsidiaries of Newco.  Each outstanding share of PSC Common Stock,
   par value $5.00 per share, will be canceled and converted into the right
   to receive 1.00 share(s) of Newco common stock par value $1.00 per share,
   and each outstanding share of SPS Common Stock, par value $1.00 per share, 
   will be canceled and converted into the right to receive 0.95 share(s) of 
   Newco Common Stock.  As of August 4, 1995, PSC had 63.1 million common
   shares outstanding and SPS had 40.9 million common shares outstanding. 
   Based on such capitalization, the Merger would result in the common
   shareholders of PSC owning  61.9% of the common equity of Newco and the
   common shareholders of SPS owning 38.1% of the common equity of  Newco. 
   The Merger Agreement and the Merger will not affect the outstanding debt,
   including mortgage bonds, and shares of preferred stock of PSC and SPS.

   It is anticipated that Newco will adopt  the SPS dividend payment level,
   adjusted for the exchange ratio.  SPS currently pays $2.20 per share
   annually and PSC's current annual dividend  rate is $2.04  per share. 
   Based on the exchange ratio, the proforma dividend for the Company would
   be $2.32 per share on an annual basis, following completion of the Merger. 
   The Company's common stock dividend level will be dependent upon the
   Company's results of operations, financial position, cash flows and other
   factors, and will be evaluated by the Board of Directors.

   The Merger is subject to customary closing conditions, including, without
   limitation, the receipt of required shareholder approvals of PSC and SPS;
   and the receipt of all necessary governmental approvals and the making of
   all necessary governmental filings, including approvals and findings of
   state utility regulators in Colorado, Texas, New Mexico, Oklahoma, Wyoming
   and Kansas and the approval of the Federal Energy Regulatory Commission,
   the Securities and Exchange Commission (the "SEC") under the 1935 Act, 

                                        2


   the Nuclear Regulatory Commission, and the filing of the requisite
   notification with the Federal Trade Commission and the Department of
   Justice under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
   amended, and the expiration of the applicable waiting period thereunder. 
   The Merger is also subject to the receipt of opinions of counsel that the
   transaction will qualify as a tax-free reorganization, and the assurances
   from the parties' independent accountants that the Merger will qualify as
   a pooling of interests for accounting purposes.  In addition, the Merger
   is conditioned upon the effectiveness of a registration statement to be
   filed with the SEC with respect to the Newco Common Stock to be issued in
   the transaction and the approval for listing of such shares on the New
   York Stock Exchange.  Shareholder meetings to vote upon the Merger will be
   convened as soon as practicable and are expected to be held in the first
   quarter of 1996.

   The Merger Agreement provides that, after the  effectiveness of the
   transaction (the "Effective Time"), the corporate offices of Newco will be
   located in Denver, Colorado with significant operating functions based in
   Amarillo, Texas.   PSC and SPS will maintain their company headquarters in
   Denver and Amarillo, respectively.  Newco's Board of Directors will
   consist of a total of 14 directors, 8 of whom will be designated by PSC
   and 6 of whom will be designated by SPS.  At the Effective Time, Delwin D.
   Hock, Chairman of the Board and Chief Executive Officer ("CEO") of PSC
   will retire. Mr. Bill D. Helton, the current Chairman of the Board and CEO
   of SPS, will serve as CEO of  Newco from the Effective Time until the
   later of (i) June 30, 1999  or (ii) 30 months from the Effective Time and
   will serve as Chairman of the Board of Newco until  May 31, 2001.  Mr.
   Wayne H.  Brunetti, the current President and Chief Operating Officer of
   PSC, will serve as Vice Chairman, President and Chief Operating Officer of
   Newco until the date when Mr. Helton ceases to be CEO, at which time he
   will be entitled to assume the additional role of CEO.  Mr. Brunetti will
   assume the position of Chairman when Mr. Helton ceases to be Chairman. 
   The forms of employment agreements for Mr. Helton and Mr. Brunetti are
   attached as exhibits to the Merger Agreement.

   The Merger Agreement contains certain covenants of the parties pending the
   consummation of the Merger.  Generally, during the interim period until
   consummation, the parties must carry on their businesses in the ordinary
   course consistent with past practice, may not increase dividends on common
   stock beyond specified levels, and may not issue capital stock beyond 
   certain limits.  The Merger Agreement  also contains restrictions on,
   among other things, charter and by-laws amendments, capital expenditures,
   acquisitions, dispositions, incurrence of indebtedness, certain increases
   in employee compensation and benefits, and affiliate transactions.

   The Merger Agreement may be terminated under certain circumstances,
   including (1) by mutual written consent of the Board of Directors of PSC
   and SPS; (2) by PSC or SPS  if the Merger is not consummated on or before
   December 31, 1996 (provided, however, that such termination date shall be
   extended to June 30, 1997 if all conditions to closing the Merger, other
   than the receipt of statutory approvals by any of the parties,  are
   capable of being satisfied by December 31, 1996);  (3) by PSC or SPS if
   approval of either PSC's or SPS's shareholders with respect to the Merger
   is not obtained or if any state or federal  law, rule or regulation or
   court order prohibits the Merger or causes a material adverse effect on
   either PSC or SPS; (4) by a non-breaching party if there exist breaches of
   any representations or warranties contained in the Merger Agreement which,
   individually or in the aggregate, would result in a material adverse
   effect on the breaching party and which are not cured within (20) days
   after notice;  (5) by a non-breaching party if there occur breaches of
   specified covenants or material breaches of any other covenant or

                                        3


   agreement which are not cured within twenty (20) days after notice; (6) by
   either party if the Board of Directors of the other party shall withdraw
   or adversely modify or fail to reaffirm its recommendation of the Merger;
   or (7) by either party, under certain circumstances, as a result of a
   third-party tender offer or business combination proposal which such
   party's board of directors determines in good faith that their fiduciary
   duties require be accepted (based on counsel's opinion), after the other
   party has first been given an  opportunity to make concessions and
   adjustments in the terms of the Merger Agreement.

   The Merger Agreement provides that if it is terminated pursuant to the
   circumstances described in clause (4), (5) or (6) of the previous
   paragraph, then, if such breach is not willful, the non-breaching or non-
   withdrawing party is entitled to reimbursement of its out-of-pocket
   expenses, not to exceed $10 million.  In the event of a willful breach or
   failure to comply, including under the circumstances described in clause
   (6) of the previous  paragraph, the non-breaching or non-withdrawing party
   will be entitled to its out-of-pocket expenses, (which shall be limited to
   $10 million) and an additional fee equal to $35 million.  In addition, the
   Merger Agreement provides that if such agreement is terminated under the
   circumstances described in clause (7) of the previous paragraph, the party
   accepting the offer shall pay to the other party an amount equal to its
   out-of-pocket expenses, not to exceed $10 million, plus an additional fee
   of $35 million, payable prior to entering into an agreement with a third
   party.  The Merger Agreement also requires payment of a termination fee of
   $35 million (and reimbursement of out-of-pocket expenses, not to exceed
   $10 million) by one party (the "Payor") to the other in certain
   circumstances, if (i) the Merger Agreement is terminated (y) under
   circumstances described in clause (2), (3), (4), (5) or (6) or (z) as a
   result of the Payor's material failure to convene a shareholder meeting,
   distribute proxy materials and, subject to its board of directors'
   fiduciary duties, recommend the Merger to its shareholders; and (ii) at
   the time of such termination or prior to the meeting of such party's
   shareholders there shall have been a third-party tender offer or business
   combination proposal which shall not have been rejected by the Payor and
   withdrawn by such third party.  Such termination fee and out-of-pocket
   expenses referred to in the previous sentence shall be paid upon
   termination.  If the Merger Agreement is terminated as provided in one of
   the first three sentences of this paragraph and if any business
   combination involving the Payor is accepted within one year of termination
   and is consummated within two and one half years from the date of
   acceptance of such business combination, the Payor shall pay to the other
   party an additional fee of $25 million.  All payments made as described in
   this paragraph, except reimbursement for out-of-pocket expenses, shall be
   payable, to the extent not prohibited by law, in shares of common stock of
   the Payor.  The termination fees payable by PSC or SPS under these
   provisions may not exceed $60 million in the aggregate, excluding
   reimbursement of out-of-pocket expenses.

   Based on fiscal 1994 results, the Company  will have combined annual
   revenues of approximately $3 billion and total assets of approximately $6
   billion.  The  companies project a savings of approximately $770 million
   in the first 10 years after the transaction is completed.  The proposed
   allocation of the net savings between ratepayers and shareholders of PSC
   and SPS will be submitted to the  various regulatory agencies later this
   year.

   The Company will serve approximately 1.5 million electric customers in
   Colorado, Texas, New Mexico,  Wyoming, Oklahoma and Kansas and will
   provide natural gas service to 933,000 customers in Colorado and Wyoming. 
   The business of the Company will consist of utility operations and various

                                        4


   non-utility enterprises, including independent power projects.

   PSC  recognizes that the divestiture of its existing gas operations is a
   possibility under the new registered holding company structure, but will
   seek approval from the SEC to maintain this business.  If divestiture is
   ultimately required, the SEC has historically allowed companies sufficient
   time to accomplish divestitures in a manner that protects shareholder
   value.

   On August 22, 1995, PSC amended (the "Rights Amendment") its Rights
   Agreement (the "Rights Agreement") dated as of February 26, 1991 between
   PSC and Mellon Bank, N.A., as Rights Agent, to provide that Newco will not
   be deemed to be an "Acquiring Person" as defined in the Rights Agreement,
   as a result of the execution, delivery and performance of the Merger
   Agreement or the consummation of the transactions contemplated therein,
   with the effect of exempting Newco and the transactions contemplated by
   the Merger Agreement from the Rights Agreement.  The foregoing description
   of the Rights Amendment is qualified in its entirety by reference to the
   terms of the Rights Amendment, a copy which is attached hereto as Exhibit
   99 (b).
