ITEM 5.  OTHER EVENTS


            Southwestern  Public  Service  Company,  a  New  Mexico  corporation
("SPS"), Public Service Company of Colorado, a Colorado corporation ("PSC"), and
M-P New Co., a newly-formed Delaware corporation ("Newco"), have entered into an
Agreement and Plan of  Reorganization,  dated as of August 22, 1995 (the "Merger
Agreement"),  which provides for a business  combination as peer firms involving
SPS and PSC 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 close  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 as Exhibits 2 and 99 to this report and are incorporated
herein by reference.  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 (the "1935 Act").  Newco,  which will serve as the  holding  
company,  will be renamed at a later date and will be the parent company of 
both SPS and PSC.

            Under the terms of the Merger Agreement, New SPS will be merged with
and into SPS and New PSC will be merged with and into PSC.  SPS and PSC shall be
the surviving  corporations  and shall continue their corporate  existence under
the laws of the State of New  Mexico  and the State of  Colorado,  respectively.
Each  outstanding  share of Common Stock, par value $1.00 per share, of SPS will
be cancelled and converted into the right to receive 0.95 shares of Common 
Stock, par value $1.00 per share, of Newco ("Newco Common Stock") and each 
outstanding share of Common Stock,  par value $5.00 per share,  of PSC will 
be cancelled and converted into the right to receive 1.0 shares of Newco Common 
Stock.  As of  August 4, 1995, SPS had 40.9 million common shares outstanding 
and PSC had 63.1 million common shares outstanding.  Based on such 
capitalization, the Merger would result in the common shareholders of SPS 
receiving 38.1% of the common equity of Newco and the common shareholders of 
PSC owning 61.9% 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 SPS and PSC.




                                    -2-




            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 annual dividend rate is currently $2.04 per share. Based on
the exchange ratio,  the pro forma dividend for Newco would be $2.32 per share
on an annual basis, following completion of the Merger.  Newco's common stock 
dividend level will be dependent upon Newco'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 SPS and
PSC; and the receipt of all necessary  governmental  approvals and the making of
all necessary  governmental  filings,  including  approvals or findings of state
utility regulators in Texas, Colorado, New Mexico, Wyoming, Oklahoma and Kansas,
the approval of the Federal  Energy  Regulatory  Commission,  the Securities and
Exchange Commission (the "SEC") under the 1935 Act and the Nuclear Regulatory  
Commission,  and the filing of the requisite  notification  with the Federal 
Trade Commission and the Department of Justice under the Hart-ScottRodino  
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 Merger 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 by Newco with the SEC 
with  respect to shares of Newco Common Stock to be issued in the Merger 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
Merger (the "Effective Time"), the corporate offices of Newco will be located in
Denver, Colorado, and significant operating offices will be located in Amarillo,
Texas.  SPS and PSC will  maintain  their company  headquarters  in Amarillo and
Denver,  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








                                    -3-



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 agreement 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,  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 bylaw  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 consent of the parties;  (2) by PSC or SPS if the Merger
is  not  consummated  by  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 the
approval of either SPS's or PSC'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 SPS or PSC;
(4) by a non-breaching  party if there exist breaches of any  representations or
warranties  contained  in the Merger  Agreement as of the date  thereof,  which,
individually or in the aggregate,  would result in a material  adverse effect on
the  breaching  party  and which are not cured  within  twenty  (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 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







                                    -4-



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 other 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









                                    -5-



extent  not  prohibited  by law,  in shares of common  stock of the  Payor.  The
termination fees payable by SPS or PSC under these provisions may not exceed $60
million in the aggregate, excluding reimbursement of out-of-pocket expenses.

            Based on  fiscal  1994  results,  Newco  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 Merger is completed. The proposed allocation of the net
savings between  ratepayers and shareholders of SPS and PSC will be submitted to
the various regulatory agencies later this year.

            Newco 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 Newco will consist of utility operations and various non-utility enterprises,
including independent power projects.

            SPS recognizes that the divestiture of PSC's existing gas operations
is a possibility  under the new registered  holding company  structure,  but the
companies  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.
