ITEM 1.  BUSINESS

                                   THE COMPANY

       Public Service Company of New Mexico (the "Company") was  incorporated in
the  State of New  Mexico  in 1917 and has its  principal  offices  at  Alvarado
Square,  Albuquerque,  New Mexico 87158  (telephone  number  505-241-2700).  The
Company is a public utility primarily  engaged in the generation,  transmission,
distribution and sale of electricity and in the  transmission,  distribution and
sale of natural gas within the State of New Mexico.  The Company is also engaged
in the  operation  and  management of the City of Santa Fe's water system and in
the  development  of new business  activities in the energy and utility  related
services area (see PART II, ITEM 7. -- "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- OVERVIEW -- Preparation for the
Changes") .

       On June 30, 1995, the Company  consummated the sale of substantially  all
of  the  gas  gathering  and  processing  assets  of the  Company  and  its  gas
subsidiaries to Williams.  On July 3, 1995, the Company  consummated the sale of
the Company's  water division to the City of Santa Fe. (See note 12 of the notes
to consolidated financial statements.)

       The total  population  of the area served by one or more of the Company's
utility services is estimated to be approximately 1.2 million, of which 55% live
in the greater Albuquerque area.

       For the year ended  December 31, 1995,  the Company  derived 72.3% of its
utility  operating  revenues  from electric  operations,  26.9% from natural gas
operations and .8% from water operations.

       As of December 31, 1995, the Company employed 2,626 persons.

       Financial information relating to amounts of revenue and operating income
and  identifiable  assets  attributable  to the Company's  industry  segments is
contained in note 13 of the notes to consolidated financial statements.

                               ELECTRIC OPERATIONS

Service Area and Customers

       The Company's electric operations serve four principal markets.  Sales to
retail customers and sales to firm-requirements  wholesale customers,  sometimes
referred to collectively as "system" sales,  comprise two of these markets.  The
third  market  consists of other  contracted  sales to  utilities  for which the
Company  commits to deliver a specified  amount of capacity  (measured in MW) or
energy (measured in MWh) over a given period of time. The fourth market consists
of economy  energy sales made on an hourly  basis to  utilities at  fluctuating,
spot-market  rates. Sales to the third and fourth markets are sometimes referred
to collectively as "off-system" sales.

       The Company  provides  retail  electric  service to a large area of north
central New Mexico,  including the cities of Albuquerque,  Santa Fe, Rio Rancho,
Las Vegas,  Belen and  Bernalillo.  The Company also  provides  retail  electric
service to Deming in southwestern  New Mexico and to Clayton in northeastern New
Mexico. As of December 31, 1995, approximately 333,000 retail electric customers
were served by the Company,  the largest of which  accounted  for  approximately
3.6% of the Company's  total  electric  revenues for the year ended December 31,
1995.

                                        1

<PAGE>

       The Company holds 23 long-term,  non-exclusive  franchise  agreements for
its electric retail operations,  expiring between August 1996 and November 2028.
The City of Albuquerque (the "City") franchise expired in early 1992.  Customers
in the area covered by the City  franchise  represent  approximately  46% of the
Company's 1995 total electric  operating  revenues,  and no other franchise area
represents  more than 6.9%.  These  franchises are  agreements  that provide the
Company access to public  rights-of-way for placement of the Company's  electric
facilities.  The Company remains obligated under state law to provide service to
customers  in the  franchise  area even in the absence of a franchise  agreement
with the City. (See PART II, ITEM 7. -- "MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- OTHER ISSUES FACING THE COMPANY
- -- ALBUQUERQUE FRANCHISE ISSUES".)

Power Sales

       For the  years  1991  through  1995,  retail  KWh sales  have  grown at a
compound annual rate of approximately  4.1%. The Company's system and off-system
sales  (revenues and energy  consumption)  and system peak demands in summer and
winter are shown in the following tables:

+      Due to the provision for the loss  associated  with the M-S-R  contingent
       power  purchase  contract   recognized  in  1992,   revenues  from  other
       contracted  off-system  sales and economy  energy sales were reduced by a
       total of $7.3 million,  $25.0 million and $20.5 million in 1995, 1994 and

       During  1995 and 1994,  the  Company's  sales in the  off-system  markets
accounted  for  approximately  24.9% and 30.8%,  respectively,  of its total KWh
sales and  approximately  11.8% and 15.8% (before reduction of revenues from the
M-S-R  contingent  power  purchase  contract,  which were  accounted  for in the
determination of the provision for loss recorded in 1992), respectively,  of its
total revenues from energy sales.  During 1995, the Company's  major  off-system
sale contracts in effect were with SDG&E and APPA.

       The SDG&E  contract  requires  SDG&E to purchase  100 MW from the Company
through April 2001. On October 27, 1993,  SDG&E filed a complaint  with the FERC
against  the  Company,  alleging  that  certain  charges  under  this 1985 power
purchase agreement are unjust, unreasonable and unduly discriminatory.  SDG&E is
requesting that the FERC investigate the rates charged under the agreement.  The
relief,  if granted,  would reduce annual demand  charges paid by SDG&E by up to
$11 million per year from the date of the ruling  through April 2001,  and could
require a refund of up to approximately  $14 million.  The Company  responded to
the complaint on December 8, 1993,  and SDG&E and the Company  filed  subsequent
pleadings.  The FERC has not  issued a ruling in the case and has not  indicated
when or if the  complaint  will be  considered.  The Company  believes  that the
complaint is without  merit,  and the Company  intends to vigorously  resist the
complaint.

       The APPA contract requires APPA to purchase varying amounts of power from
the Company through May 2008 and allows APPA to make adjustments to the purchase
amounts subject to certain notice  provisions.  APPA provided notice that it was
invoking  its option to reduce  the power  demand in 1995,  resulting  in a peak
demand of 89 MW.

       The Company furnished  firm-requirements wholesale power in New Mexico in
1995 to the cities of Farmington and Gallup,  TNP and Plains.  Plains terminated
its contract for 10 MW in 1995.  The Company is committed to provide  service to
the City of Gallup through April 2003. Average monthly demands under the City of
Gallup contract for 1995 were  approximately 26 MW. TNP is currently  purchasing
36 MW but has provided notice that it will reduce its purchase to 15 MW for 1996
and 1997.  TNP may  adjust its  annual  demand  between 15 MW and 40 MW with one
year's  notice  and  may   terminate   service  with  two  years'   notice.   No
firm-requirements  wholesale  customer  accounted  for  more  than  1.6%  of the
Company's  total  electric  operating  revenues for the year ended  December 31,
1995.

Sources of Power

       As of December 31, 1995, the total net generation  capacity of facilities
owned or leased by the Company was 1,506 MW.

       In addition, the Company has a power purchase contract with SPS for up to
200 MW from May 1995 through May 2011. The Company may reduce its purchases from
SPS by 25 MW annually upon three years' notice. The Company provided such notice
in 1995 to reduce the purchase by 25 MW in 1999.  Also, the Company has 39 MW of
contingent  capacity  obtained  from El Paso under a  transmission  capacity for
generation  capacity trade arrangement that increases to 70 MW from 1998 through
2003.  In addition,  the Company is  interconnected  with various  utilities for
economy interchanges and mutual assistance in emergencies.

       The  Company  anticipates  the  need for  approximately  100 to 200 MW of
additional  generating  capacity  in the 1998  through  2000  timeframe,  and is
currently pursuing its options to meet these capacity needs.

Fuel and Water Supply

       The percentages of the Company's  generation of electricity (on the basis
of KWh) fueled by coal,  nuclear fuel and gas and oil, and the average  costs to
the  Company of those  fuels (in cents per  million  BTU),  during the past five
years were as follows:


                         Coal                 Nuclear            Gas and Oil
                 -------------------   -------------------   -------------------
                 Percent of  Average   Percent of  Average   Percent of  Average
                 ----------  -------   ----------  -------   ----------  -------

1991............    67.1      167.9       32.9       67.9       --        216.5
1992............    69.2      161.7       30.5       59.8       0.3       239.7
1993............    72.9      164.7       26.7       58.1       0.4       331.7
1994............    72.0      162.9       27.8       58.5       0.2       321.7

       The estimated  generation  mix for 1996 is 71.5% coal,  28.4% nuclear and
0.1% gas and oil. Due to locally  available  natural gas and oil  supplies,  the
utilization of locally available coal deposits and the generally abundant supply
of  nuclear  fuel,  the  Company  believes  that  adequate  sources  of fuel are
available for its generating stations.

Coal

       The coal requirements for SJGS are being supplied by SJCC, a wholly-owned
subsidiary of BHP, from certain  Federal,  state and private coal leases under a
Coal Sales  Agreement,  pursuant  to which SJCC will supply  processed  coal for
operation of SJGS until 2017. BHP  guaranteed the  obligations of SJCC under the
agreement,  which contemplates the delivery of approximately 121 million tons of
coal during its remaining term. Such amount would supply  substantially  all the
requirements of SJGS through approximately 2017. The primary sources of coal are
a mine adjacent to SJGS and a mine located  approximately  25 miles northeast of
SJGS in the La Plata area of northwestern  New Mexico.  The Company is currently
discussing  with SJCC  alternatives  for securing  both short and long term fuel
resource  requirements  which at this  time are  uncommitted.  As a part of this
discussion,  the Company is also  negotiating  other  issues which may result in
modifications to certain Coal Sales Agreement terms and provisions which include
but are not limited to cost  recovery  and pricing.  On  September 1, 1995,  the
parties  executed  an  amendment  to the Coal  Sales  Agreement.  The  amendment
provides for flexibility in coal sourcing.  Mining  operations are being shifted
over time to the La Plata Mine and several newly  introduced  sources  including
expanded La Plata reserves and a new lease contiguous with the existing San Juan
Mine.  While  the  savings  in fuel  cost  over  the  life of the  contract  are
continuing to be developed, it is currently estimated that the Company will save
approximately  $200  million of coal fuel costs  during the period 1996  through
2004.  The average cost of fuel,  including  ash  disposal and land  reclamation
costs,  for SJGS for the years 1993, 1994 and 1995 was 177.4 cents,  172.1 cents
and 184.6 cents,  respectively,  per million BTU ($34.59,  $33.62 and $35.75 per
ton, respectively).

       Four  Corners is supplied  with coal under a fuel  agreement  between the
owners and BHP, under which BHP agreed to supply all the coal  requirements  for
the life of the plant. BHP holds a long-term coal mining lease, with options for
renewal,  from the Navajo  Nation and  operates  a strip mine  adjacent  to Four
Corners with the coal supply  expected to be  sufficient to supply the units for
their estimated useful lives.  The average cost of fuel,  including ash disposal
and land  reclamation  costs,  for the years 1993, 1994 and 1995 at Four Corners
was 114.9  cents,  125.8 cents and 113.4  cents,  respectively,  per million BTU
($20.11, $22.03 and $20.04 per ton, respectively).

Natural Gas

       The  natural  gas used as fuel  for the  Company's  Albuquerque  electric
generating  plant  (Reeves  Station) is  delivered by PNMGS.  (See  "NATURAL GAS
OPERATIONS".)  In addition to rate changes  under filed  tariffs,  the Company's
cost of gas  increases  or  decreases  according  to the average cost of the gas
supply.

Nuclear Fuel

       The fuel cycle for PVNGS is comprised of the  following  stages:  (1) the
mining and  milling of uranium  ore to  produce  uranium  concentrates,  (2) the
conversion of uranium concentrates to uranium  hexafluoride,  (3) the enrichment
of  uranium  hexafluoride,  (4)  the  fabrication  of fuel  assemblies,  (5) the
utilization  of fuel  assemblies in reactors,  and (6) the storage of spent fuel
and the disposal  thereof.  The Company has made  arrangements  through contract
flexibilities  to obtain  quantities of uranium  concentrates  anticipated to be
sufficient to meet its share of uranium concentrates  requirements through 2000.
The  Company's  existing  contracts and options could be utilized to meet 75% of
such  requirements  in 2001 and 2002 and 40% of  requirements  from 2003 through
2007.  The  Company   understands  that  other  PVNGS   participants  have  made
arrangements  for the  uranium  concentrate  requirements  through  2000.  Their
existing  contracts and options could be utilized to meet 80% of requirements in
1998 and  1999  and 70% of  requirements  from  2000  through  2006.  The  PVNGS
participants,  including the Company,  contracted  for all  conversion  services
required  through  2000  with  options  for up to 70%  through  2002.  The PVNGS
participants,  including the Company,  also have an enrichment services contract
with USEC which obligates USEC to furnish  enrichment  services required for the
operation of the three PVNGS units over a term expiring in September  2002, with
options to continue through September 2007.

       Existing spent fuel storage facilities at PVNGS have sufficient  capacity
with certain  modifications  to store all fuel  expected to be  discharged  from
normal  operation  of all of the PVNGS  units  through  at least the year  2005.
Pursuant to the Nuclear Waste Policy Act of 1982, as amended in 1987 (the "Waste
Act"),  DOE is  obligated  to accept and dispose of all spent  nuclear  fuel and
other  high-level  radioactive  wastes generated by all domestic power reactors.
The NRC,  pursuant to the Waste Act,  also  requires  operators of nuclear power
reactors to enter into spent fuel disposal  contracts  with DOE. APS, on its own
behalf  and on behalf of the other  PVNGS  participants,  executed  a spent fuel
disposal  contract  with DOE.  The Waste Act also  obligates  DOE to develop the
facilities  necessary for the permanent disposal of all spent fuel generated and
to be generated by domestic  power  reactors and to have the first such facility
in operation by 1998 under prescribed procedures. In November 1989, DOE reported
that such a permanent  disposal facility will not be in operation until 2010. As
a result,  under DOE's current criteria for shipping allocation rights,  PVNGS's
spent fuel  shipments  to the DOE  permanent  disposal  facility  would begin in
approximately 2025. In addition, APS believes that on-site storage of spent fuel
may be required beyond the life of the PVNGS Units. APS currently  believes that
alternative  interim spent fuel storage methods are or will be available on-site
or off-site for use by PVNGS to allow its continued operation beyond 2005 and to
safely store spent fuel until DOE's scheduled shipments from PVNGS begin.

       Currently,  low-level  radioactive  waste is being stored on-site.  A new
low-level  waste  facility was built in 1995 on the PVNGS site. The new facility
has the capability to store an amount of waste  equivalent to 10 years of normal
operation of PVNGS.  APS, the operating agent of PVNGS, is currently  evaluating
its options of shipping  low-level  waste to  facilities  that have  reopened or
continuing to store the waste in the new facility.

       While believing that scientific and financial  aspects of the issues with
respect to spent fuel and low-level  waste can be resolved  satisfactorily,  APS
acknowledges  that their  ultimate  resolution in a timely  fashion will require
political  resolve and action on national and  regional  scales which it is less
able to predict.

Water Supply

       Water for Four Corners and SJGS is obtained from the San Juan River. (See
ITEM 3. -- "LEGAL PROCEEDINGS -- SAN JUAN RIVER ADJUDICATION".) BHP holds rights
to San Juan  River  water and has  committed  a portion  of such  rights to Four
Corners through the life of the project.  The Company and Tucson have a contract
with the United States Bureau of Reclamation for consumption of 16,200 acre feet
of water per year for SJGS, which contract expires in 2005, and in addition, the
Company was granted the  authority to consume  8,000 acre feet of water per year
under a state  permit that is held by BHP.  The  Company is of the opinion  that
sufficient water is under contract for SJGS until 2005.

       On January  29,  1993,  the U.S.  Fish and  Wildlife  Service  proposed a
portion of the San Juan River as  critical  habitat for two fish  species.  This
designation  may impact uses of the river and its flood  plains and will require
certain  analysis  under the Endangered  Species Act of 1973 of all  significant
Federal actions.  Renewal of the SJGS water contract is considered a significant
Federal action.

       Due to extensive lead times required to renew the water rights  contract,
the Company  has  formally  initiated  the  renewal  and  extension  process for
requesting  rights through the year 2025. The Company is actively  conducting an
environmental  assessment  with  the  Bureau  of  Reclamation  and a  biological
assessment with the U.S. Fish and Wildlife  Service.  These studies are required
by the Federal  agencies before the existing water contract can be renewed.  The
Company is currently unable to predict the outcome of these matters.

       Sewage  effluent used for cooling  purposes in the operation of the PVNGS
units has been obtained under contracts with certain municipalities in the area.
The contracted  quantity of effluent  exceeds the amount  required for the three
PVNGS  units.  The  validity  of these  effluent  contracts  is the  subject  of
litigation in state and Federal  courts.  (See ITEM 3. -- "LEGAL  PROCEEDINGS --
PVNGS WATER SUPPLY LITIGATION".)

                             NATURAL GAS OPERATIONS

       On June 30, 1995, the Company,  Gathering Company and Processing  Company
sold  substantially  all of their gas gathering and processing  facilities.  The
Company  believes  that the sale  allows the Company to focus on  providing  gas
transportation  and  retail gas  services  to New  Mexico  gas  consumers  while
maintaining  its  flexibility in accessing  competitively  priced,  reliable and
secure gas  supplies.  (See PART II,  ITEM 7. --  "MANAGEMENT'S  DISCUSSION  AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- OTHER ISSUES FACING
THE COMPANY -- SALE OF GAS GATHERING AND PROCESSING ASSETS".)

Service Area and Customers

       The Company's gas operating division,  PNMGS,  distributes natural gas to
most of the major communities in New Mexico, including Albuquerque and Santa Fe,
serving approximately 393,000 customers as of December 31, 1995. The Albuquerque
metropolitan  area accounts for approximately  54.7% of the total  sales-service
customers.   PNMGS  holds  long-term,   non-exclusive  franchises  with  varying
expiration dates in all incorporated communities requiring franchise agreements.
PNMGS completed  franchise  negotiations with the City of Santa Fe extending the
franchise   through  October  25,  2020.  PNMGS'  customer  base  includes  both
"sales-service" customers and "transportation-service"  customers. Sales-service
customers purchase natural gas and receive  transportation and delivery services
from  PNMGS  for which  PNMGS  receives  both  cost-of-gas  and  cost-of-service
revenues.  Cost-of-gas  revenues  collected from  sales-service  customers are a
recovery  of the cost of  purchased  gas in  accordance  with  NMPUC  rules  and
regulations  and, in that sense,  do not affect the net earnings of the Company.


                                        6

<PAGE>



Transportation-service  customers,  who procure gas  independently  of PNMGS and
contract with PNMGS for transportation and related services,  provide PNMGS with
cost-of-service  revenues  only.  Transportation  services  are  provided to gas
marketers generally for delivery to locations  throughout the PNMGS distribution
systems, to natural gas producers generally for delivery to interstate pipelines
and directly to  end-users.  PNMGS  provided gas  transportation  deliveries  to
approximately 1,200 gas marketers and producers during 1995.

       For the twelve months ended  December 31, 1995,  PNMGS had  throughput of
approximately 110 million decatherms, including sales of 37.3 million decatherms
to sales-service  customers.  No single  "sales-service"  customer accounted for
more than 1.5% of PNMGS' therm sales in 1995. During 1995,  approximately  63.7%
of the PNMGS' total gas throughput was related to transportation gas deliveries.
PNMGS' transportation rates are unbundled, and transportation customers only pay
for the amount of  transportation  service they receive.  PNMGS' total operating
revenues  for the year  ended  December  31,  1995,  were  approximately  $218.0
million. Cost-of-gas revenues, received from sales-service customers,  accounted
for  approximately  39.7% of  PNMGS'  total  operating  revenues.  Since a major
portion of PNMGS' load is related to heating, levels of therm sales are affected
by the weather. Approximately 44.2% of PNMGS' total therm sales in 1995 occurred
in the months of January, February, November and December.

Natural Gas Supply

       During the late 1980's, there were significant changes in the natural gas
industry  brought  about by Federal  and state  regulations  which  dramatically
altered the way gas is bought,  transported and sold  nationwide.  These changes
required  PNMGS to reform or terminate  certain  natural gas purchase  contracts
which required PNMGS to take gas in excess of demand.  This process  resulted in
breach of contract  claims from some  producers.  PNMGS has been able to resolve
substantially all of the producer  litigation and reform its supply portfolio so
that it better  matches the  demands of PNMGS'  sales-service  customers.  These
reformations have also allowed PNMGS to seek new sources of gas supplies through
pipeline  interconnects  which have created a more flexible and reliable  supply
portfolio. PNMGS obtains its supply of natural gas primarily from sources within
New Mexico  pursuant to contracts with producers and marketers.  These contracts
are generally sufficient to meet the PNMGS's peak-day demand.

       PNMGS serves certain cities which depend on EPNG or Transwestern Pipeline
Company  for  transportation  of gas  supplies.  Because  these  cities  are not
directly connected to PNMGS's transmission facilities,  gas transported by these
companies is the sole supply source for those  cities.  Such  transportation  is
regulated  by  FERC.  As  a  result  of  FERC  Order  636,  PNMGS'  options  for
transporting  gas to such cities and other portions of its  distribution  system
have increased.

*      Customer-owned gas
**     On June 30, 1995, the Company sold substantially all of the gas gathering
       and processing assets of the Company and its gas subsidiaries.  The above
       information reflects the revenues and throughput of the gathering company
       and processing company through this date.

                              RATES AND REGULATION

       The Company is subject to the  jurisdiction  of the NMPUC with respect to
its retail electric and gas rates, service, accounting,  issuance of securities,
construction  of major new  generation  and  transmission  facilities  and other
matters.  The FERC has  jurisdiction  over  rates and other  matters  related to
wholesale electric sales.

FPPCAC

       The Company's  firm-requirements  wholesale customers have a FPPCAC which
has an approximate  30-day time lag in  implementation of the FPPCAC for billing
purposes. The Company's FPPCAC for its firm-requirement  wholesale customers had
been at variance with the filed FERC tariffs.  As a result,  the Company filed a
petition with FERC on October 28, 1993 to request  deviation from the filed FERC
tariffs for the period of July 1985 through  January 1993. The Company's  filing
indicated that the four firm-requirements  wholesale customers benefitted during
that time period  relative to the energy costs they would have been billed under
the application of the filed FERC tariffs.  The four affected  customers  concur
with the Company's  position and have filed a certificate  of  concurrence  with
FERC.  Discussions regarding the Company's filing with FERC staff have occurred,
but at this time no formal  response has been given to the Company.  The Company
has no  indication  of when a formal  response  will be received;  however,  the
Company  does not  anticipate  any  material  adverse  impact  on the  Company's
financial condition or results of operations as a result of this issue.

fossil-fueled   generating  stations  are  expected  to  incur  dismantling  and
reclamation   costs  as  they  are   decommissioned.   The  Company's  share  of
decommissioning  costs  for  all of its  fossil-fueled  generating  stations  is
projected to be  approximately  $141 million  stated in 1995 dollars,  including
approximately  $24.0 million (of which $12.1 million has already been  expended)
for Person, Prager and Santa Fe Stations which have been retired.

       The Company is currently recovering estimated  decommissioning costs from
NMPUC retail customers through its depreciation rates.  Depreciation amounts for
the retired generating units are not being recovered.

Energy and Utility Related Subsidiaries

       On June 23, 1995, the Company filed an application for  authorization for
the creation of three wholly-owned subsidiaries to: (i) manage and operate water
and wastewater systems;  (ii) pursue energy marketing,  alternative fuel vehicle
services and energy  management  services;  and (iii) pursue utility  management
services and related energy  management  services for Federal  installations and
large commercial  customers.  The Company sought approval to invest a maximum of
$50  million in the three  subsidiaries  over time and to enter into  reciprocal
loan agreements for up to $30 million with these  subsidiaries.  The NMPUC Staff
filed a motion on September 20, 1995 to have the case dismissed.  On January 31,
1996, the hearing examiner  assigned to the case recommended that the NMPUC deny
the Staff's  motion.  On February 5, 1996,  the Staff filed a motion  seeking to
have the Company file an immediate report on its non-regulated  activities being
conducted  without  prior  NMPUC  approval;  explain  why NMPUC  approval is not
required;  and explain why  sanctions  should not be  considered  if approval is
required.  On February 19, 1996,  the Company filed its response  describing its
non-utility  (energy and utility  related)  activities  and presenting the legal
authority  demonstrating that prior NMPUC approval is not required.  The Company
currently  cannot predict the ultimate outcome of this proceeding but intends to
vigorously  defend against any  allegation  that it is in violation of any legal
requirements.

Gas Rate Case

       On August 28,  1995,  the  Company  filed a request  for a $13.3  million
increase in its retail natural gas sales and  transportation  rates. NMPUC Staff
and intervenors in the case filed their testimony on January 16, 1996. The Staff
recommended a $2.5 million rate decrease and the AG  recommended a $14.7 million
rate decrease.  The major issues in the case center around the Company's request
to recover certain costs  associated with reservation  fees,  discounts given to
large and industrial  transportation  customers and losses incurred to reacquire
debt. The Company  anticipates  that it will have deferred as regulatory  assets
approximately  $22 million related to these items through July 1, 1996, the date
when rates are anticipated to go into effect. The Company will file its rebuttal
testimony  on  February  23,  1996 and  hearings  will  begin on March 4,  1996.
Although  the Company  cannot  predict the  ultimate  outcome of this case,  the
Company believes that it has meritorious  claims and will vigorously  pursue the
recovery of these assets.

PGAC Continuation Filing

       Retail  gas rate  schedules  contain a PGAC  which  provides  for  timely
recovery of the cost of gas purchased for resale to its sales-service customers.
On April 20, 1993, PNMGS filed its application  requesting authority to continue
the use of its PGAC.  An item  included  in this  application  was a request  to
recover reservation fees as a cost of gas through the PGAC. On October 26, 1995,
the Hearing Examiner issued a Recommended Decision allowing,  among other items,
the  continued  use of the PGAC but  recommended  that  reservation  fees not be
recoverable  through the PGAC.  PNMGS filed an  exception  to the portion of the
Recommended Decision relating to reservation fees. PNMGS is awaiting final NMPUC
approval.  PNMGS is  attempting to recover  these same  reservation  fees in the
ongoing  general rate  proceeding  (see "Gas Rate Case" above).  On February 19,
1996, the NMPUC issued an order requiring PNMGS to file  supplemental  testimony
regarding the volatile nature of its gas costs.

       In a related proceeding, the NMPUC on September 18, 1995, issued a Notice
of Inquiry  seeking  comments  as to whether  the NMPUC  rule that  governs  the
operation of PGACs should be amended.  In November 1995, the Company joined with
the NMPUC  Staff  and the AG in  recommending  that  such rule be  substantially
rewritten.

Consolidation Issues

       Pursuant to a prior NMPUC  order,  the Company  filed an  application  in
December 1993 for NMPUC approval to combine certain customer  service  functions
of its gas and electric  utility  divisions  in order to achieve more  efficient
operations  and to improve  service to customers.  At the same time, the Company
filed a separate request for a declaratory  order from the NMPUC confirming that
the Company's realignment of senior corporate officers'  responsibilities during
1993  complies  with  a  1984  NMPUC  order   placing   certain   organizational
restrictions  on the operation of the gas and electric  divisions.  In 1994, the
NMPUC consolidated the two proceedings.

       In January  1995,  the Company and the staff of the NMPUC  entered into a
stipulation  regarding the consolidated cases. The stipulation  provides for the
approval of the  consolidation of certain customer service  functions of the gas
and  electric  divisions,  as  proposed by the  Company.  The  stipulation  also
provides  for the  dismissal  of the  declaratory  order  proceeding  without  a
determination  that the  Company's  1993 or 1994  organizational  structure  was
either in  compliance  or not in  compliance  with the 1984 NMPUC order.  In May
1995, the NMPUC issued its final order approving the stipulation.  In its order,
the NMPUC stated that it was  explicitly  not ruling at this time on whether the
Company's 1993-1994  organization has harmed the public interest. The NMPUC also
approved  the phase-in of  consolidation  of certain  customer  services for one
year. During this period, the Company is required to submit semi-annual  reports
to the NMPUC on the costs and savings of customer service consolidation.

Legislative Action

       In the recent legislature  session which ended February 15, 1996, the New
Mexico  Legislature  approved a  constitutional  amendment which would alter the
current state regulatory system relating to the electric utility industry in New
Mexico. If approved by voters at the next general election in November 1996, the
amendment to the state  constitution  would replace the existing NMPUC and State
Corporate Commission with a single,  elected regulatory body. Beginning in 1999,
the new five-member  "Public Regulation  Commission" would regulate electric and
gas utilities as well as telecommunications,  cable TV, insurance,  trucking and
all other entities  presently  regulated under current state law. The Company is
neutral on this proposed change.

                              ENVIRONMENTAL FACTORS

       The Company, in common with other electric and gas utilities,  is subject
to stringent  regulations  for  protection of the  environment by both state and
Federal authorities.  PVNGS is subject to the jurisdiction of the NRC, which has
authority to issue  permits and licenses and to regulate  nuclear  facilities in
order to protect  the health and safety of the public from  radioactive  hazards
and to conduct  environmental  reviews  pursuant to the  National  Environmental
Policy Act.  The Company  believes  that it is in  compliance,  in all  material
respects,  with the  environmental  laws. The Company does not currently  expect
that material expenditures for environmental control facilities will be required
in 1996 and 1997.

The Clean Air Act

       The Clean Air Act amendments of 1990 (the "Act") impose  stringent limits
on emissions of sulfur dioxide and nitrogen oxides from  fossil-fueled  electric
generating  plants.  The Act is intended to reduce air contamination  from every
sizeable  source  of  air  pollution  in the  nation.  Electric  utilities  with
fossil-fueled  generating units will be affected  particularly by the section of
the Act which  deals  with acid rain.  To be in  compliance  with the Act,  many
utilities  will be  faced  with  installing  expensive  sulfur  dioxide  removal
equipment,  securing low sulfur coal, buying sulfur dioxide emission allowances,
or a combination of these. Due to the existing air pollution  control  equipment
on the coal-fired SJGS and Four Corners,  the Company  believes that it will not
be faced with any material  capital  expenditures  in order to be in  compliance
with the acid rain  provision of the Act.  SJGS and Four Corners have  installed
flow  monitoring  equipment and have  completed  certification  testing of their
continuous  emission  monitoring  equipment.   Certification  testing  data  was
submitted to the EPA on January 30,  1995,  as  required.  Certification  of the
monitoring  systems by the EPA is expected.  Under other  provisions of the Act,
the  Company  will be  required  to obtain  operating  permits for its coal- and
gas-fired  generating units and to pay annual fees associated with the operating
permit program.  The New Mexico operating permit program was approved by the EPA
in November 1994.  Operating permit  applications were submitted to the state in
1995. The state has not issued any operating permits.

       The Act also established the Grand Canyon Visibility Transport Commission
("Commission")  and charged it with assessing  adverse  impacts on visibility at
the Grand  Canyon.  The  Commission  broadened  its  scope to assess  visibility
impairment in mandatory  Class I areas (parks and  wilderness  areas) located in
the Colorado Plateau ("Golden Circle"). The Commission must report to the EPA by
June 1996 on its findings and make  recommendations  regarding what actions,  if
any,  should be  pursued  in order to remedy the  visibility  impairment  in the
Golden Circle.  Depending on the recommendations of the Commission,  the EPA may
require stricter  controls on sources that may be contributing to the visibility
impairment.  Both SJGS and Four Corners are located near the Golden Circle.  The
exact nature and cost of additional controls,  if any, that may be required as a
result of the recommendations cannot be estimated at this time.

        *  For load and  resource  purposes,  the Company has notified the NMPUC
           that it recognizes the maximum  dependable  capacity rating for PVNGS
           to be 375 MW.
- -----------------

         (a)    The  Company  is  entitled  to 10.2%  of the  power  and  energy
                generated by PVNGS.  The Company has a 10.2% ownership  interest
                in Unit 3 and has leasehold interests in Units 1 and 2.
         (b)    SJGS Units 1, 2 and 3 are 50% owned by the Company;  SJGS Unit 4
                is 38.457% owned by the Company.
         (c)    Four Corners Units 4 and 5 are 13% owned by the Company.

Fossil-Fueled Plants

       SJGS is located in  northwestern  New Mexico,  and consists of four units
operated by the Company.  Units 1, 2, 3 and 4 at SJGS have net rated  capacities
of 316 MW, 312 MW, 488 MW and 498 MW, respectively. SJGS Units 1 and 2 are owned
on a 50% shared basis with Tucson. Unit 3 is owned 50% by the Company,  41.8% by
SCPPA and 8.2% by Tri-State Generation and Transmission Association, Inc. Unit 4
is owned 38.457% by the Company,  8.475% by Farmington,  28.8% by M-S-R, 7.2% by
Los Alamos,  10.04% by Anaheim and 7.028% by UAMPS.  The Company's net aggregate
ownership in SJGS is 750 MW. In connection  with the Company's  sale to M-S-R in
December 1983 of a 28.8% interest in SJGS Unit 4, the Company agreed to purchase
under certain  conditions  73.53% (105 MW) of M-S-R's capacity through April 30,
1995. The Company also agreed to market the energy associated with the remaining
26.47% portion of M-S-R's capacity through April 30, 1995.

       The Company also owns 192 MW of net rated  capacity  derived from its 13%
interest in Units 4 and 5 of Four Corners located in northwestern  New Mexico on
land leased from the Navajo  Nation and  adjacent to  available  coal  deposits.
Units 4 and 5 at Four  Corners  are  jointly  owned  with SCE,  APS,  Salt River
Project, Tucson and El Paso and are operated by APS.

                                       12

<PAGE>
       The  Company  owns 154 MW of  generation  capacity  at Reeves  Station in
Albuquerque,  New Mexico, and 20 MW of generation  capacity at Las Vegas Station
in Las Vegas,  New Mexico.  These  stations are used  primarily  for peaking and
transmission support.

Nuclear Plant

The Company's Interest in PVNGS

       The Company is participating  in the three 1,270 MW units of PVNGS,  also
known as the Arizona Nuclear Power Project, with APS (the operating agent), Salt
River Project,  El Paso, SCE, SCPPA and The Department of Water and Power of the
City of Los Angeles.  The Company has a 10.2% undivided  interest in PVNGS, with
its interests in Units 1 and 2 held under leases. In September 1992, the Company
purchased approximately 22% of the beneficial interests in the PVNGS Units 1 and
2 leases for approximately $17.5 million.  The Company's ownership and leasehold
interests in PVNGS amount to 130 MW per unit,  or a total of 390 MW. PVNGS Units
1, 2 and 3 were declared in  commercial  service by the Company in January 1986,
September  1986 and January 1988,  respectively.  Commercial  operation of PVNGS
requires  full  power  operating   licenses  which  were  granted  by  the  NRC.
Maintenance of these licenses is subject to NRC regulation.

       During 1995,  PVNGS was operated at a capacity  factor of 83.6%.  This is
the  highest  yearly  capacity  factor that has been  attained at the plant.  In
addition, PVNGS operating costs declined and the length of refueling outages was
significantly  reduced.  Recently,  an  independent  organization  that  reviews
nuclear  plants for safety and  effectiveness  of  operation  awarded  PVNGS the
highest rating possible.

Steam Generator Tubes

       For information concerning steam generator tubes, see PART II, ITEM 7. --
"MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS  -- OTHER  ISSUES  FACING  THE  COMPANY  -- PVNGS -- STEAM  GENERATOR
TUBES".

Sale and Leaseback Transactions of PVNGS Units 1 and 2

       In eleven transactions consummated in 1985 and 1986, the Company sold and
leased back its entire  10.2%  interest in PVNGS  Units 1 and 2,  together  with
portions of the Company's undivided interest in certain PVNGS common facilities.
In each  transaction,  the Company sold  interests to an owner  trustee under an
owner trust agreement with an institutional equity investor. The owner trustees,
as lessors,  leased the interests to the Company under lease  agreements  having
initial terms  expiring  January 15, 2015 (with respect to the Unit 1 leases) or
January 15,  2016 (with  respect to the Unit 2 leases).  Each lease  provides an
option to the  Company to extend  the term of the lease as well as a  repurchase
option. The lease expense for the Company's PVNGS leases is approximately  $66.3
million per year.  Throughout the terms of the leases,  the Company continues to
have full and exclusive authority and responsibility to exercise and perform all
of the rights and duties of a  participant  in PVNGS under the  Arizona  Nuclear
Power Project  Participation  Agreement and retains the exclusive  right to sell
and dispose of its 10.2% share of the power and energy  generated by PVNGS Units
1 and 2. The Company also retains responsibility for payment of its share of all
taxes,  insurance  premiums,  operating and maintenance  costs, costs related to
capital  improvements  and  decommissioning  and all  other  similar  costs  and
expenses  associated  with the leased  facilities.  On  September  2, 1992,  the
Company  purchased  approximately  22% of the beneficial  interests in the PVNGS
Units  1  and  2  leases  for  $17.5  million.  For  accounting  purposes,  this
transaction was recorded as a purchase with the Company recording  approximately
$158.3  million as utility  plant and $140.8  million as  long-term  debt on the
Company's  consolidated balance sheet. In connection with the $30 million retail
rate  reduction,  the Company wrote down the purchased  beneficial  interests in


                                       13

<PAGE>
PVNGS Units 1 and 2 leases to $46.7 million.  In March 1995, the Company retired
approximately $130 million of PVNGS lease obligation bonds ("LOBs").

       Each lease  describes  certain  events,  "Events of Loss" or "Deemed Loss
Events",  the  occurrence  of which could  require  the Company to,  among other
things,  (i)  pay the  lessor  and the  equity  investor,  in  return  for  such
investor's  interest in PVNGS,  cash in the amount provided in the lease,  which
amount, primarily because of certain tax consequences,  would exceed such equity
investor's  outstanding  equity  investment,  and (ii) assume  debt  obligations
relating  to  the  PVNGS  lease.  The  "Events  of  Loss"  generally  relate  to
casualties,  accidents and other events at PVNGS, which would severely adversely
affect the ability of the operating agent,  APS, to operate,  and the ability of
the  Company to earn a return on its  interests  in,  PVNGS.  The  "Deemed  Loss
Events"  consist mostly of legal and regulatory  changes (such as changes in law
making the sale and leaseback transactions illegal, or changes in law making the
lessors liable for nuclear  decommissioning  obligations).  The Company believes
the  probability  of such "Events of Loss" or "Deemed Loss Events"  occurring is
remote.  Such belief is based on the following  reasons:  (i) to a large extent,
prevention  of  "Events  of Loss" and some  "Deemed  Loss  Events" is within the
control  of the  PVNGS  participants,  including  the  Company,  and  the  PVNGS
operating  agent,  through the general PVNGS  operational  and safety  oversight
process and (ii) with respect to other "Deemed Loss Events," which would involve
a  significant  change in current law and policy,  the Company is unaware of any
pending  proposals or proposals being considered for introduction in Congress or
any state legislative or regulatory body that, if adopted,  would cause any such
events.

PVNGS Decommissioning Funding

       For information  concerning PVNGS  decommissioning  funding, see PART II,
ITEM 7.  --"MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF FINANCIAL  CONDITION  AND
RESULTS  OF  OPERATIONS  -- OTHER  ISSUES  FACING THE  COMPANY -- PVNGS  NUCLEAR
DECOMMISSIONING".

PVNGS Liability and Insurance Matters

       The PVNGS  participants  have  insurance  for public  liability  payments
resulting  from  nuclear  energy  hazards to the full limit of  liability  under
Federal law. This potential  liability is covered by primary liability insurance
provided by commercial  insurance carriers in the amount of $200 million and the
balance  by an  industry-wide  retrospective  assessment  program.  The  maximum
assessment per reactor under the  retrospective  rating program for each nuclear
incident  occurring  at  any  nuclear  power  plant  in  the  United  States  is
approximately  $79.3  million,  subject to an annual  limit of $10  million  per
incident.  Based upon the Company's 10.2% interest in the three PVNGS units, the
Company's  maximum  potential  assessment  per incident is  approximately  $24.3
million,  with an annual  payment  limitation of $3 million.  The insureds under
this liability insurance include the PVNGS participants and "any other person or
organization with respect to his legal  responsibility  for damage caused by the
nuclear energy hazard".  The PVNGS participants  maintain "all-risk"  (including
nuclear hazards)  insurance for nuclear property damage to, and  decontamination
of, property at PVNGS in the aggregate amount of approximately  $2.75 billion as
of  January  1,  1996,  a  substantial  portion  of  which  must be  applied  to
stabilization  and  decontamination.  The  Company  has also  secured  insurance
against a  portion  of the  increased  cost of  generation  or  purchased  power
resulting from certain accidental outages of any of the three PVNGS units if the
outage exceeds 21 weeks.

Other Electric Properties

       Four Corners and a portion of the facilities adjacent to SJGS are located
on land held under  easements  from the United States and also under leases from
the Navajo Nation,  the enforcement of which leases might require  Congressional
consent. The risk with respect to the enforcement of these easements

                                       14

<PAGE>
and leases is not deemed by the Company to be material.  However, the Company is
dependent in some measure upon the  willingness and ability of the Navajo Nation
to protect these properties.  (See PART II, ITEM 7. -- "MANAGEMENT'S  DISCUSSION
AND ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF  OPERATIONS -- OTHER ISSUES
FACING THE COMPANY -- TRANSMISSION ISSUES -- Transmission Right-of-Way".)

       As of December 31, 1995, the Company owned, jointly owned or leased 2,789
circuit  miles of  electric  transmission  lines,  5,279  miles of  distribution
overhead lines,  3,109 cable miles of underground  distribution lines (excluding
street lighting) and 225 substations.

                                   NATURAL GAS

       The natural gas property as of December 31, 1995  consisted  primarily of
natural gas storage,  transmission  and  distribution  systems.  Provisions  for
storage made by the Company  include  ownership and operation of an  underground
storage  facility  located near  Albuquerque  and an agreement  with owners of a
unitized oil field  located near Artesia,  New Mexico,  in which the Company has
injection and redelivery rights. The Company has agreed to terminate the storage
agreement  with owners of the  unitized  oil field and plans to withdraw all gas
stored in that facility by April 1996.  The  transmission  systems  consisted of
approximately 1,256 miles of pipe with appurtenant compression  facilities.  The
distribution systems consisted of approximately 9,898 miles of pipe.

       The Company leases  approximately 98 miles of transmission  pipe from the
DOE for  transportation  of  natural  gas to Los  Alamos  and to  certain  other
communities in northern New Mexico.  The lease can be terminated by either party
on 30 days written notice, although the Company believes it has the right to use
the facility for two years after  termination.  The DOE has  announced  plans to
sell the  pipeline and issued a draft  Request for  Proposal  with a schedule to
complete the sale of the pipeline by September  30, 1996.  Several  right-of-way
and regulatory issues remain to be resolved making the scheduled completion date
questionable.  The Company has been and will  continue to be highly  involved in
the process.

                                OTHER INFORMATION

       The electric and gas transmission  and  distribution  lines are generally
located within easements and rights-of-way on public,  private and Indian lands.
The Company leases  interests in PVNGS Units 1 and 2 and related  property,  EIP
and  associated  equipment,  data  processing,  communication,  office and other
equipment,  office space,  utility poles (joint use),  vehicles and real estate.
The Company also owns and leases  service and office  facilities in  Albuquerque
and in other operating divisions throughout its service territory.

ITEM 3.  LEGAL PROCEEDINGS

                          PVNGS WATER SUPPLY LITIGATION

       The validity of the primary effluent contract under which water necessary
for the operation of the PVNGS units is obtained was  challenged in a suit filed
in  January  1982  by  the  Salt  River  Pima-Maricopa   Indian  Community  (the
"community") against the Department of the Interior,  the Federal agency alleged
to have  jurisdiction  over the use of the  effluent.  The  PVNGS  participants,
including the Company,  were named as additional  defendants in the  proceeding,
which is before the United  States  District  Court for the District of Arizona.
The portion of the action  challenging  the  effluent  contract  has been stayed
until the  community  litigates  certain  claims in the same action  against the
Department of the Interior and other  defendants.  On October 21, 1988,  Federal
legislation was enacted conforming to the requirements of a proposed  settlement
that would  terminate  this case without  affecting  the validity of the primary
effluent contract. However, certain contingencies are to be performed before the


                                       15

<PAGE>



settlement is finalized and the suit is dismissed. One of these contingencies is
the approval of the  settlement  by the court in the Lower Gila River  Watershed
litigation referred to below.

       The  Company  understands  that a  summons  served  on APS in early  1986
required  all water  claimants  in the Lower Gila River  Watershed of Arizona to
assert any claims to water on or before  January 20, 1987, in an action  pending
in the Maricopa County  Superior  Court.  PVNGS is located within the geographic
area subject to the summons and the rights of the PVNGS  participants to the use
of  groundwater  and effluent at PVNGS are  potentially at issue in this action.
APS,  as the PVNGS  project  manager,  filed  claims  that  dispute  the court's
jurisdiction  over  the  PVNGS   participants'   groundwater  rights  and  their
contractual  rights to  effluent  relating  to PVNGS  and,  alternatively,  seek
confirmation of such rights. No trial date has been set in this matter.

       Although the foregoing matters remain subject to further evaluation,  APS
expects that the described litigation will not have a material adverse impact on
the operation of PVNGS.

                           SAN JUAN RIVER ADJUDICATION

       In 1975,  the State of New Mexico filed an action  entitled  State of New
Mexico v. United States,  et al., in the District Court of San Juan County,  New
Mexico,  to adjudicate  all water rights in the "San Juan River Stream  System".
The Company  was made a  defendant  in the  litigation  in 1976.  The action was
expected to adjudicate  water rights used at Four Corners and at SJGS. (See ITEM
1.  "BUSINESS -- ELECTRIC  OPERATIONS  -- Fuel and Water  Supply".)  The Company
cannot  at this  time  anticipate  the  effect,  if  any,  of any  water  rights
adjudication on the present  arrangements for water at SJGS and Four Corners. It
is the  Company's  understanding  that final  resolution  of the case  cannot be
expected for several years.

                              PVNGS PROPERTY TAXES

       On June 29, 1990, an Arizona  state tax law was enacted,  effective as of
December 31, 1989, which adversely  impacted the Company's earnings in the years
of 1990 through 1995 by approximately $5 million per year,  before income taxes.
On December 20, 1990,  the PVNGS  participants,  including the Company,  filed a
lawsuit in the Arizona Tax Court,  a division of the  Maricopa  County  Superior
Court,  against the Arizona Department of Revenue, the Treasurer of the State of
Arizona,  and various  Arizona  counties,  claiming,  among other  things,  that
portions of the new tax law are  unconstitutional.  In December  1992, the court
granted  summary  judgment to the taxing  authorities,  holding  that the law is
constitutional.  The PVNGS  participants  appealed  this decision to the Arizona
Court of Appeals.  On November 21, 1995,  the Arizona  Court of Appeals ruled in
favor of the PVNGS participants. Due to the significance of this decision, it is
anticipated  that the case will be  further  pursued  through  the  courts.  The
Company cannot currently predict the ultimate outcome of this matter.

                                OTHER PROCEEDINGS

FederalDeposit Insurance  Corporation ("FDIC")  Litigation,  formerly Resolution
       Trust Corporation ("RTC") Litigation ("MDL-995")

       On March 31, 1993,  certain  individuals  ("the New Mexico  Plaintiffs"),
formerly affiliated with BCD, whose general partners include Meadows, filed suit
("the New Mexico suit") in the United States  District Court for the District of
New Mexico against numerous parties,  including the Company,  current and former
employees of the Company or Meadows,  and MCB Financial Group,  Inc., a Delaware
corporation  ("MCB"),  50% of which  stock is owned by  Meadows.  The New Mexico
Plaintiffs  did not request any monetary  relief  against the Company or certain
current and former employees of the Company and Meadows but have

                                       16

<PAGE>
joined  those  parties  in  connection  with  insurance  coverage  and bad faith
insurance  practices  alleged  against the insurance  company which had issued a
directors and officers  liability policy to various entities,  including MCB and
BCD. The insurance  allegations  are made in  connection  with claims which were
then threatened by the RTC, as receiver for Western  Savings & Loan  Association
("Western"), against the Company and others. The New Mexico Plaintiffs also sued
the RTC for a  declaration  that they are not liable for any claims  asserted by
the RTC  involving  Western  and BCD.  The  Company  and the  current and former
employees  of the  Company  or  Meadows  counterclaimed  against  the New Mexico
Plaintiffs  and  cross-claimed  against  the  insurance  company  and the RTC in
connection  with  insurance  coverage  and bad  faith  insurance  practices.  In
addition,  the Company and the  current and former  employees  of the Company or
Meadows cross-claimed against the RTC, seeking a declaration of non-liability.

       The RTC moved to transfer the case to the United  States  District  Court
for the  District  of  Arizona.  On  February  7,  1994,  an order  was  entered
transferring the case in its entirety.  Prior to the transfer,  however, the New
Mexico  magistrate  judge  issued a proposed  order  which,  if  accepted by the
district  judge,  would  require the parties to enter into  mediation of all the
claims.  The parties to the New Mexico  suit  reached  agreement  on a dismissal
without  prejudice of the claims  remaining in that suit, and on April 22, 1995,
the Court  entered an order  dismissing  the case without  prejudice.  Under the
terms of the proposed order of dismissal,  a motion for sanctions  filed against
the RTC by the Company and other  parties to the suit  (which  asserts  that RTC
engaged in bad faith settlement negotiations) remains pending before the Arizona
court.

       On April 16, 1993, the Company and certain  current and former  employees
of the Company or Meadows  were named as  defendants  in an action  filed in the
United States District Court for the District of Arizona by the RTC, as receiver
for Western.  Three of the individuals sued by the RTC have indemnity agreements
with the  Company.  The claims  relate to alleged  actions of the  Company's  or
Meadows'  employees in 1987 in  connection  with a loan  procured by BCD,  whose
general  partners  include  Meadows,  from  Western  and  the  purchase  by that
partnership  of property owned by Western.  The RTC  apparently  claims that the
Company's  liability  stems from the actions of a former  employee who allegedly
acted on behalf of the Company for the Company's benefit. The RTC is claiming in
excess of $40 million in actual damages from the BCD/Western transactions and is
also  claiming   damages   substantially   exceeding   that  amount  on  Arizona
racketeering,   civil  conspiracy  and  aiding  and  abetting  theories.   These
allegations  involve claims against the Company for damages to Western caused by
other  defendants and from other  transactions to which BCD was not a party. The
Company is sued only on the  Arizona  racketeering  claims.  The RTC claims that
damages under the Arizona racketeering statute would be trebled under applicable
Arizona law. The  prevailing  parties on the Arizona  racketeering  claims could
seek their fees and costs from the parties who do not prevail.

       In May 1994,  the RTC filed a motion  seeking to amend the  complaint  to
allege  against  the  Company  civil  conspiracy,  common law  fraud,  negligent
misrepresentation,  aiding and abetting breach of fiduciary  duties,  aiding and
abetting common law fraud,  aiding and abetting violation of Federal and Arizona
racketeering  laws  (all of  which  claims  are  already  asserted  against  the
Company's  current and former employees named in the suit) and claims seeking to
hold the Company liable on undisclosed principal and unjust enrichment theories.
The Company filed an opposition to the motion and, in September  1994, the Court
denied the RTC's  motion to amend.  Previously,  the Court  dismissed  the RTC's
claims  for  aiding  and  abetting   violations   of  the  Federal  and  Arizona
racketeering  laws against the Company,  the current and former employees of the
Company or Meadows and others.

       Subsequent  to the  Court's  denial  of the  RTC's  motion  to amend  the
complaint,  the RTC filed a motion  seeking to amend the case  management  order
previously  entered by the Court. The purpose of the motion was to allow the RTC
to file an amended complaint which would include the allegations against the

                                       17

<PAGE>
Company  sought by the motion to amend that was denied by the Court in September
1994. On November 7, 1994, the Court denied this new motion.

       On  December  31,  1995,  the RTC  ceased  to exist  and its  duties  and
responsibilities were transferred to the FDIC. The FDIC has been substituted for
the RTC as plaintiff in MDL-995.

       The  Company  and the  current  and former  employees  of the  Company or
Meadows sued by the RTC continued to have settlement  negotiations  with the RTC
during  its  existence,  but  those  efforts  were  not  successful.  Settlement
discussions will continue with the FDIC.

       The Company  continues to investigate  all of the claims made by the FDIC
in this litigation and is vigorously  defending those claims. The Company cannot
predict  the  ultimate  outcome  of  the  case  but  believes  that  the  FDIC's
contentions  are without merit and currently  believes that the outcome will not
result in a material  adverse  impact on the Company's  results of operations or
financial condition.

Four Corners

       The  Company  owns a 13%  ownership  interest  in  Units  4 and 5 of Four
Corners  located  in  northwestern  New  Mexico on land  leased  from the Navajo
Nation.  APS is the operating agent. In July 1995, the Navajo Nation enacted the
Navajo Nation Air Pollution  Prevention  and Control Act, the Navajo Nation Safe
Drinking  Water Act and the  Navajo  Nation  Pesticide  Act  (collectively,  the
"Acts").  By letter  dated  October  12,  1995,  the Four  Corners  participants
requested  the United  States  Secretary of the Interior  (the  "Secretary")  to
resolve their dispute with the Navajo Nation  regarding  whether or not the Acts
apply to operation of Four Corners. The Four Corners  participants  subsequently
filed a lawsuit in the District Court of the Navajo Nation (the "Court"), Window
Rock District, seeking, among other things, a declaratory judgment that: (i) the
Four Corners leases and Federal  easements  preclude the application of the Acts
to the  operation of Four  Corners;  and (ii) the Navajo Nation and its agencies
and courts lack adjudicatory jurisdiction to determine the enforceability of the
Acts as applied to Four Corners.  On October 18, 1995, the Navajo Nation and the
Four Corners participants agreed to indefinitely stay the proceedings referenced
above so that the parties may attempt to resolve the dispute without litigation,
and have requested that the Secretary and the Court stay these proceedings.  The
Company is unable to predict the outcome of this matter.

ITEM 7.       MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                  AND RESULTS OF OPERATIONS

     The  following  is  management's  assessment  of  the  Company's  financial
condition and the significant factors affecting the results of operations.  This
discussion  should  be read  in  conjunction  with  the  Company's  consolidated
financial statements.

                                    OVERVIEW

Competitive Electric Market

     The  electric  utility  industry  is  currently   undergoing  a  period  of
fundamental  change intended to promote a competitive  environment in the retail
and wholesale energy marketplaces.  Legislators and regulators at both the state
and Federal level are considering whether, and how, to promote competition among
suppliers  of  electricity  and  how to  provide  customers  with  choice  among
suppliers.

     At the Federal level, the FERC promulgated a Notice of Proposed Rule Making
("Mega-NOPR")  in March 1995,  which  proposes to require  utilities to unbundle
their  generation  and   transmission   services  and  to  provide  open  access
transmission.  The  Mega-NOPR  also  supplemented  a prior NOPR  concerning  the
appropriate  treatment of stranded asset costs  associated  with the transition.
Specifically,  the FERC  stated  that  recovery  of  legitimate  and  verifiable
stranded  asset costs is critical to the  successful  transition of the electric
utility industry from a tightly  regulated  cost-of-service  industry to an open
transmission access,  competitively priced industry. The Company in its response
to the Mega-NOPR supported the FERC initiative toward open access  transmission,
but  requested  that all  transmission  asset  owners,  including  municipal and
Federal,  be  subject to the same  requirements  in order to  establish  a level
playing field for all participants in the electric utility industry. The Company
also agreed with the FERC  regarding  the  proposed  recovery of stranded  asset
costs.  A final  decision on the Mega-NOPR is expected in the middle of 1996. On
January 22, 1996, a U.S. Senate bill, "Electricity  Competition Act of 1996" was
introduced,  providing a national framework for a competitive  electric industry
by no later than the year 2010. The bill provides for recovery of stranded asset
costs. On February 14, 1996, the Council of Economic Advisors issued an economic
report to Congress in which it  cautioned  that  electric  industry  competition
should ensure competitive  benefits to all power buyers and should not aggravate
pollution  or cause  supply  cuts to the poor.  The report  favors  recovery  of
stranded  asset costs borne by all parties on whose  behalf the  stranded  costs
were   incurred,   including   customers   that   switch  to  other   suppliers.
Representative Dan Schaeffer,  Chairman of the Energy  Subcommittee of the House
of  Commerce  Committee,  has  announced  that he plans to conduct  hearings  on
electric industry  restructuring,  possibly  beginning this summer.  The Company
does not expect  Congressional  legislation  to pass this year,  but does expect
Congressional interest to continue next year.

     In November  1995,  after three years of study,  the  Integrated  Water and
Resource  Planning  Committee of the New Mexico State  Legislature (the "IWRPC")
issued a resolution  reporting its findings on the advantages and  disadvantages
of retail  wheeling and  alternative  restructuring  schemes  applicable  to the
electric power industry in New Mexico.  The IWRPC's  recommendation  stated that
any proposed  restructuring  (i) must benefit all ratepayers in the state,  (ii)
must maintain and possibly encourage the financial health and economic viability
of each of the state's utilities,  (iii) must provide for appropriate protection
from unfair or advantaged  competition from utilities or others from outside the
state, and (iv) must share equitably any costs,  including stranded asset costs,
among the  varied  interests  benefitted.  The IWRPC also  recommended  that the
NMPUC, under legislative direction and guidance, should monitor and evaluate the
electric power industry and applicable  market influences and factors and report
its  findings,   conclusions  and   recommendations  to  the  New  Mexico  State
Legislature  for  legislative  approval  and action,  as  necessary,  before any
proposed restructuring may be implemented. The resolution further indicated that

                                       23

<PAGE>
this  continuing  evaluation  was necessary  because of continuing  changes even
though  restructuring  and retail  wheeling  are not  justified or in the public
interest  at  this  time.  The  IWRPC  resolution  was  presented  to  the  full
Legislature as a Senate Joint Memorial.  It was unanimously passed by the Senate
and the House.

     In  November  1995,  the NMPUC  issued a Notice of  Inquiry  regarding  the
restructuring of regulation of the electric utility industry in New Mexico.  The
NMPUC is seeking input on a variety of questions related to competition,  retail
wheeling  and state vs.  Federal  jurisdiction.  The Company in its February 15,
1996 response  stated that it believes that: (i) competition and customer choice
may be beneficial to all affected  interests in New Mexico if done appropriately
and (ii) in order to achieve restructuring,  there must be cooperative state and
Federal action to avoid  prolonged  uncertainty  and  litigation,  as well as to
avert   inconsistent  state  actions  that  would  inhibit  the  development  of
competitive markets and restrict the benefits that they may provide. The Company
proposed  a  five-year  period  to  accomplish  the  transition  to  a  workable
competitive  market.  The Company  also  stated  that it supports  action by the
United  States  Congress  to  clarify   boundaries  between  state  and  Federal
jurisdiction  over the  electric  utility  industry,  and to ensure  that retail
wheeling  can be  implemented  in a manner that  ensures  fair  competition  and
provides utilities the opportunity to recover all stranded asset costs.

     Although it is uncertain as to the ultimate outcome of possible open access
or retail wheeling  initiatives,  the Company will continue to be active at both
the state and Federal levels in the public policy debate on the restructuring of
the  electric  utility  industry.  By working  with  customers,  regulators  and
legislators,  the Company  believes that an agreement  will be reached that will
protect the interests of stockholders as well as offer the potential benefits of
a competitive marketplace to all customers.

Uncertainties

     The future  structure of the industry,  the form and timing of  competition
and the method of regulation in a competitive  environment remain uncertain.  If
retail wheeling is implemented,  it is possible that, based on other deregulated
industries' experiences,  retail energy prices could drop significantly.  Should
that  be  the  case,  the  value  of  a  utility's   assets  could  be  affected
significantly in the transition to a more competitive  market from a traditional
rate regulated environment.  Currently, the Company's generation costs are above
those of  neighboring  utilities to the north and east of the Company's  service
territory.

     The Company believes that the 1994 electric retail rate reduction  improved
its competitive  position,  but recognizes that lower cost producers may have an
advantage if the  regulatory  framework  changes  significantly  towards  retail
wheeling.   The  Company's  owned  nuclear   capacity  is  currently  valued  at
approximately  $900 per KW. If the  Company  were  required  to value its leased
nuclear  capacity at the same level as its owned nuclear  capacity,  it would be
valued at approximately $180 million versus approximately $560 million. If there
were no provision for the recovery of stranded asset costs, the Company would be
required to charge against earnings approximately $380 million.

Preparation for the Changes

     In order to mitigate the exposures  associated with a competitive  electric
market and transition into this changing  environment,  the Company  established
the  following  strategic  plan in 1995:  (i) secure  financial  flexibility  by
retiring debt,  (ii) control  operation and  maintenance  costs,  (iii) focus on
maximizing shareholder value for the nuclear generation assets, and (iv) develop
new business  opportunities  in the energy and utility  related area. As part of
this plan, the Company restructured its operation into four distinctive business
units, each targeted at a specific segment of its customer base with emphasis on
being  more  customer  oriented  and  responsive  to  the  changing  competitive
environment. The four business units are as follows: (i) Electric Services, (ii)
Gas Services, (iii) Bulk Power Services and (iv) Energy Services.


                                       24

<PAGE>
     In order to maximize value of the nuclear  generation assets, the Company's
board of directors  (the  "Board"),  at its December 5, 1995 meeting,  confirmed
that it is in the best interest of the Company at this time to focus its efforts
and resources on maximizing shareholder value from PVNGS as an asset (leased and
owned) of the Company rather than  disposing of it. Growth in the region,  rapid
growth  in  the  Company's  own  local  service  territory  and  the  continuous
improvement  in the operating  performance  of the plant were all factors in the
change of approach.  The Board stated that the Company no longer considers it to
be a goal to dispose of its interests in PVNGS.

     In  conjunction  with the  development of new business  opportunities,  the
Company focused on three energy and utility related  activities under its Energy
Services Unit. These activities will provide energy marketing,  alternative fuel
vehicle services and energy management services focused on residential and small
customers,  management  services  for water and  wastewater  systems and utility
related  management and operation  services for Federal  installations and other
large commercial institutions. The Company believes that successful operation of
these ventures will better position the Company in an  increasingly  competitive
utility  environment.  The  Company is  currently  seeking  NMPUC  approval  for
investment  in energy  and  utility  related  subsidiaries  under the  Company's
general  diversification  plan. The NMPUC Staff filed a motion in September 1995
to have the case dismissed.  On January 31, 1996, the hearing examiner  assigned
to the case recommended  that the NMPUC deny the Staff's motion.  On February 5,
1996,  the Staff filed a motion  seeking to have the Company  file an  immediate
report on its  non-regulated  activities  being  conducted  without  prior NMPUC
approval;  explain why NMPUC approval is not required; and explain why sanctions
should not be  considered  if approval is required.  On February  19, 1996,  the
Company  filed its  response  describing  its  non-utility  (energy  and utility
related) activities and presenting the legal authority  demonstrating that prior
NMPUC  approval  is not  required.  The  Company  currently  cannot  predict the
ultimate outcome of this proceeding but intends to vigorously defend against any
allegation that it is in violation of any legal requirements.

                         LIQUIDITY AND CAPITAL RESOURCES

Capital Requirements

     Total capital  requirements  include  construction  expenditures as well as
other major  capital  requirements,  including  retirement  of  long-term  debt,
preferred  stock and long-term  debt sinking funds and preferred  stock dividend
requirements. The main focus of the construction program is upgrading generating
systems,   upgrading  and  expanding  the  electric  and  gas  transmission  and
distribution  systems,  and purchasing nuclear fuel. Total capital  requirements
for 1995 and  projections  for 1996-2000 are $367.4 million and $676.8  million,
respectively.  These  estimates  are under  continuing  review  and  subject  to
on-going adjustment.

     The Company  currently  anticipates  that internal cash  generation will be
sufficient to meet capital  requirements  during 1996 through 2000. To cover the
difference in the amounts and timing of cash  generation and cash  requirements,
the  Company  intends  to  utilize  short-term  borrowings  under its  liquidity
arrangements.

Liquidity and Financing

     The  Company's  construction  expenditures  for 1995 were  entirely  funded
through  cash  generated  from  operations.   In  addition  to  cash  flow  from
operations,  the Company received  approximately $206.5 million from the sale of
gas gathering and processing  assets and the Company's  water  division.  During
1995, the Company retired approximately $133 million of PVNGS LOBs, redeemed, at
par,  $64  million  of the  Company's  cumulative  preferred  stock and  retired
approximately  $58  million of other  long-term  debt.  At the end of 1995,  the
Company had $96 million of temporary investments and no short-term borrowings.

                                       25

<PAGE>
In addition, at year-end 1995, the Company had available liquidity  arrangements
of $151 million,  consisting of a $100 million secured revolving credit facility
("Facility"),  $40  million  credit  facility  collateralized  by the  Company's
electric customer accounts receivable (the "Accounts  Receivable  Facility") and
$11 million in local lines of credit. On January 30, 1996, the Company requested
NMPUC approval to increase the capacity of the Accounts  Receivable  Facility up
to $100 million by including in the  collateral  pool the Company's gas accounts
receivable and certain  amounts being  recovered from gas customers  relating to
certain gas  contract  settlements.  The  Facility  will expire in June 1998 and
includes a maximum allowed debt to  capitalization  ratio of 70%. As of December
31, 1995, such ratio was 65%.

     The Company's  ability to finance its construction  program at a reasonable
cost and to  provide  for other  capital  needs is  largely  dependent  upon its
ability to earn a fair return on equity, results of operations,  credit ratings,
regulatory approvals and financial market conditions.  Financing  flexibility is
enhanced by  providing a high  percentage  of total  capital  requirements  from
internal  sources  and having the  ability,  if  necessary,  to issue  long-term
securities, and to obtain short-term credit. All of the Company's securities are
rated below  investment  grade by  Standard & Poor's  Corp.,  Moody's  Investors
Service and Fitch Investors  Service,  Inc.,  which may result in limited credit
markets being available  and/or higher  financing  costs to the Company.  Duff &
Phelps Credit Rating Co.  maintains an investment grade rating for the Company's
first  mortgage  bonds,  but  continues  to  rate  all  other  of the  Company's
securities below investment grade.

Financing Capability and Dividend Restrictions

     One impact of the Company's current ratings, together with covenants in the
Company's  PVNGS  Units  1 and 2  lease  agreements  (see  PART  I,  ITEM  2. --
"PROPERTIES  -- Nuclear  Plant"),  is to limit the  Company's  ability,  without
consent of the owner participants and bondholders in the lease transactions, (i)
to enter into any merger or  consolidation,  or (ii) except in  connection  with
normal dividend policy, to convey,  transfer,  lease or dividend more than 5% of
its assets in any single  transaction  or series of  related  transactions.  The
Facility  and a  reimbursement  agreement  associated  with the letter of credit
supporting  $37.3  million of pollution  control  revenue  bonds impose  similar
restrictions irrespective of credit ratings.

     The issuance of first  mortgage bonds by the Company is subject to earnings
coverage  and bondable  property  provisions  of the  Company's  first  mortgage
indenture.  The Company also has the  capability  under the mortgage  indenture,
without  regard to the earnings test but subject to other  conditions,  to issue
first  mortgage  bonds on the basis of  certain  previously  retired  bonds.  At
December 31, 1995,  based on the earnings  test,  the Company  could have issued
approximately  $124 million of  additional  first  mortgage  bonds,  assuming an
annual  interest  rate of 9.25  percent.  The  Company's  restated  articles  of
incorporation limit the amount of preferred stock which may be issued.  Assuming
a preferred  stock dividend rate of 9.75 percent,  the Company could have issued
$381 million of preferred stock as of year-end.

     The Company  currently has no requirements  for long-term  financing during
the period of 1996 through 2000. However,  during this period, the Company could
enter into  long-term  financings for the purpose of  strengthening  its balance
sheet and  reducing its cost of capital.  The Company  continues to evaluate its
investment and debt  retirement  options to optimize its financing  strategy and
earnings  potential.  The Company  currently plans to retire  approximately  $90
million of long-term debt in 1996.

     The Company has not declared  dividends  on its common stock since  January
1989 and  anticipates  announcing a dividend plan sometime before the end of the
second quarter of 1996. The Company's  board of directors  reviews the Company's
dividend  policy on a continuing  basis.  The resumption of common  dividends is
dependent upon a number of factors including earnings and financial condition of
the  Company  and market  conditions.  The  deficit  in  retained  earnings  was
eliminated during 1995.

     *   Total  capitalization  does  not  include  the  present  value  of  the
         Company's lease obligations for PVNGS Units 1 and 2 and EIP as debt but
         does  include,  for  1994  and  1993,  the  debt  associated  with  the
         beneficial interests in certain PVNGS Units 1 and 2 leases purchased by
         the Company, which were retired in March 1995.

                              RESULTS OF OPERATIONS

     Net earnings per common share in 1995 were $1.72,  compared to net earnings
of $1.77 per common  share in 1994 and a loss of $1.64 per common share in 1993.
The loss  experienced  in 1993 was due to the  Company  recording  an  after-tax
charge of $108.2 million to earnings resulting from the write-down in connection
with the Company's $30 million retail electric rate reduction.

     The financial  performance  of the excluded  resources has been improved by
the PVNGS Unit 3 write-down and the provision for loss associated with the M-S-R
power purchase  contract recorded in 1992. The gains from the sale of generating
facilities to Anaheim recorded in August 1993 and to UAMPS recorded in June 1994
have also improved the financial performance of the excluded resources.

     A number of items  contributed to the $3.5 million decrease in net earnings
of the excluded  resources as compared with 1994 results.  The most  significant
item was the  UAMPS  gain  recorded  in June  1994.  Operating  results  for the
excluded  resources  for all these  periods  reflect the  allocation of interest
charges  based on the  average  investment  in excluded  net utility  plant as a
percent of total utility plant for the period.

     Selected  financial  information for the excluded  resources for 1995, 1994
and 1993 is shown below:

     The following discussion  highlights other significant items which affected
the results of operations in 1995,  1994 and 1993, and certain items expected to
impact future earnings.

     Electric gross margin (electric  operating revenues less fuel and purchased
power expense)  decreased $37.9 million in 1995 due to the retail rate reduction
implemented in late 1994, reduced off-system sales as a result of the expiration
of three sales contracts and generally poor wholesale  power market  conditions.
Partially  offsetting  such  decreases  was  the  increase  in  retail  revenues
resulting from retail sales growth.

                                       27

<PAGE>
     Electric  gross margin  increased  $32.3  million in 1994 compared to 1993,
$23.2  million of which was due to an increase in  jurisdictional  energy sales.
This  increase was  partially  due to warmer  weather and a  difference  of $6.7
million  between the  estimated  unbilled  revenues  reported in 1993 and actual
unbilled revenues in 1994.

     Gas gross margin (gas  operating  revenues  less gas  purchased for resale)
decreased $16.4 million from a year ago due to a decrease of $5.5 million in gas
deliveries  resulting from warmer than normal weather in 1995 and reduced margin
of $11.7 as a result of the gas  gathering  and  processing  assets sale in June
1995.  Gas gross  margin  decreased  $5.1  million in 1994 from 1993.  Principal
factors were the write-off of certain  deferred charges relating to costs of gas
and a decrease in gas  deliveries  resulting from a warmer than normal winter in
1994.

     Other operation and maintenance expenses ("O&M") decreased $12.3 million in
1995 due to the following: (i) a $2.1 million decrease in PVNGS O&M expense as a
result of a reduction in scheduled  maintenance  outage hours and lower property
taxes in the current  period,  (ii)  decreased Four Corners O&M expenses of $2.0
million  resulting from a maintenance  outage of Unit 4 in 1994, (iii) decreased
SJGS O&M expenses of $1.7 million resulting from lower maintenance  outage hours
in 1995,  (iv) a decrease in gas production and products  extraction  expense of
$6.2 million  resulting from the gas assets sale in June 1995, (v) a decrease in
injuries  and damages  expense of $4.5  million as a result of the  recording of
workers' compensation liability in 1994, (vi) lower office supplies and expenses
of $3.0 million as a result of a decrease in temporary  office labor and postage
expense and (vii) a decrease in water O&M expense of $2.1 million resulting from
the sale of the  Company's  water  division in July 1995.  Such  decreases  were
partially offset by (i) higher  administrative and general labor expense of $4.7
million,  (ii) higher  employee  benefit  expense of $2.7 million  caused by the
retroactive  deferral  of the gas  operation's  retirees  health  care costs for
regulatory  purposes  recorded in 1994 and (iii) higher  production O&M expenses
for the gas and oil-fired plants of $1.7 million  resulting from the maintenance
outages in 1995.

     Other O&M  expenses  decreased  $5.1  million  in 1994 from 1993 due to the
following:  (i) a $10.6  million  decrease  as a result  of the  Company's  1993
severance program, (ii) a deferral of gas operation's retirees health care costs
of $2.8  million for  regulatory  purposes and (iii) lower  electric  regulatory
commission expense of $2.1 million.  Offsetting such decrease was the following:
(i)  increased  pension  and  retirees  health care cost of $3.0  million,  (ii)
increased electric  distribution  expense of $3.6 million due to weather-related
outages and increased tree trimming activity, (iii) increased generating station
maintenance  expense of $2.4 million and (iv)  increased  workers'  compensation
liability of $2.2 million.

     Depreciation and amortization  expenses  increased $6.7 million from a year
ago as a result of the  implementation of new depreciation rates approved by the
NMPUC in November 1994.

     Other,  under the caption  Other  Income and  Deductions,  increased  $44.2
million  from a  year  ago  and  increased  $9.3  million  in  1994  from  1993.
Significant  1995 items, net of taxes,  included the following:  (i) the gain of
$12.8  million  recognized  from the sale of the gas  gathering  and  processing
assets,  (ii) the gain of $6.4 million recognized from the sale of the Company's
water division,  (iii) an after-tax accrual of $2.6 million of income pertaining
to the carrying costs related to gas take-or-pay settlement amounts, (iv) income
of $1.9 million for insurance recovery and (v) income of $1.4 million related to
adjusting   reclamation  reserves  for  certain  mining  operations.   Partially
offsetting  such  increases  were: (i)  additional  regulatory  reserves of $4.8
million and (ii) write-downs of $1.8 million for various non-utility properties.

     Significant  1994 items,  net of taxes,  included  the  following:  (i) the
write-off of $3.0 million relating to gas take-or-pay  settlement payments which
are not recoverable through rates, (ii) additional  provisions for legal expense
of $3.6  million and (iii) a gain and  associated  tax  benefits of $6.1 million
from the sale of generating facilities to UAMPS.

                                       28

<PAGE>
     Significant 1993 items, net of taxes, included the following:  (i) the gain
of $7.5 million  recognized  from the sale of an  investment,  (ii) the gain and
associated  tax benefits of $7.6 million from the sale of generating  facilities
to Anaheim and (iii) tax benefits of $3.2  million  from the Federal  income tax
rate change  which  allows the Company to utilize  its net  operating  loss at a
higher tax rate.  Partially  offsetting  such  increases  were:  (i)  additional
provisions for legal and litigation  expenses of $5.7 million,  (ii) a write-off
of $4.6  million of other  deferred  costs,  (iii)  PVNGS  decommissioning  fund
adjustment of $2.8 million and (iv) a write-off of $2.1 million  resulting  from
costs associated with refunding certain  pollution control and EIP bonds,  which
represents the amount related to FERC  firm-requirement  wholesale customers and
resources excluded from New Mexico jurisdictional rates.

     Net interest  charges  decreased  $12.7  million in 1995 as a result of the
retirement of $130 million of PVNGS LOBs in March 1995 and the retirement of $45
million of first  mortgage  bonds in April 1994. In 1994,  net interest  charges
decreased  $15.2  million  compared  to 1993.  Major  factors  were:  (i)  lower
short-term borrowings in 1994, (ii) the refinancing of $182 million of pollution
control  revenue bonds in January ($46 million) and September  ($136 million) of
1993 and (iii) the  retirement of $45 million of first  mortgage  bonds in April
1994.

     Preferred stock dividend  requirements  decreased $2.7 million in 1995 as a
result of the retirement of $64 million of preferred stock in August 1995.

                         OTHER ISSUES FACING THE COMPANY

TRANSMISSION ISSUES

OLE Transmission Project

     OLE, a proposed 345 Kv transmission line connecting the existing Ojo 345 Kv
line to the Norton  Station in northern  New Mexico,  was  designed to provide a
needed improvement to the northern New Mexico  transmission  system and to allow
greater  delivery of power into the Company's two largest  service  territories,
the greater  Albuquerque  area and the Santa  Fe/Las  Vegas area.  OLE has faced
considerable  opposition by persons concerned  primarily about the environmental
impacts of the project.

     The Company filed in 1991 for NMPUC  approval for  construction  of OLE. On
November 20, 1995, the NMPUC issued a final order  disapproving the project.  On
December 20, 1995, the Company filed a limited  Motion for Rehearing,  accepting
the NMPUC's determination that the OLE routing should not be pursued but seeking
reconsideration  of  various  parts of the  final  order  which  discuss  system
planning  and  reliability  matters.  The NMPUC took no action on the  Company's
request which in effect deemed it denied.  The Company has elected not to appeal
the NMPUC order or denial of rehearing.  The Company has incurred  approximately
$17  million  for the OLE project  and has  established  accounting  reserves as
deemed  appropriate.  The  Company  intends to seek  recovery  of these costs as
legitimate and prudent costs in future appropriate proceedings.

Transmission Right-of-Way

     The Company  has  easements  for  right-of-way  with the Navajo  Nation for
portions of several  transmission  lines that deliver the  Company's  generation
resources  to the  Albuquerque  metropolitan  area.  One grant of  easement  for
approximately  4.2 miles of  right-of-way  for two parallel 345 Kv  transmission
lines  expired  in 1993.  Prior to the  expiration,  the  Company  had  numerous
unsuccessful  negotiation meetings with the Navajo Nation for the renewal of the
long-term  grant.  In 1994, the Navajo Nation  adopted a Civil Trespass  Statute
providing for civil penalties, damages and other remedies, including removal, to
be imposed for  unconsented or unauthorized  use of Navajo Nation lands.  During


                                       29

<PAGE>



1995,  the Company  reached a tentative  agreement  with the Navajo Nation for a
twenty-year  renewal of the transmission  easement and a resolution of all other
transmission  right-of-way  issues.  Prior to the  execution  of the  agreement,
another agency of the Navajo Nation  notified the Company that it was contesting
certain  water  rights  at  the  SJGS,  which  has  delayed  resolution  of  the
transmission  right-of-way issues. The Company continues to work with the Navajo
Nation to resolve this conflict.

      The Company  continues  to assess its options  but is not  pursuing  other
alternatives unless it receives indications that settlement cannot be reached in
a satisfactory  manner.  The Company currently cannot predict the outcome of the
negotiations or the costs resulting  therefrom;  however,  the Company  believes
that  resolution  of this issue will not have a material  adverse  impact on the
Company's financial condition or results of operations.

Transmission Disputes

     The Company receives approximately $14.0 million annually for the provision
of firm  transmission  service to several  customers.  Most of these  customers,
through various  actions,  have initiated  formal FERC  investigations  into the
transmission  service  billing  units  and  transmission  rates  charged  by the
Company. If these various allegations and requested rate reductions are approved
by the FERC, the Company's  revenues for transmission  services could be reduced
by  as  much  as $9  million  annually.  The  Company  has  responded  to  these
allegations and has requested that the FERC dismiss the complaints.  The Company
is currently  awaiting the FERC decision.  In a related FERC filing, the Company
committed  to file,  on or before  April 1,  1996,  a rate  change for all firm,
point-to-point  and network  service  transmission  customers,  including  those
customers  that  have  filed  the  pending  complaints.   Although  the  Company
anticipates a reduction in rates resulting from the filing, the Company does not
anticipate any material adverse impact on the Company's  financial  condition or
results of operations.

SALE OF GAS GATHERING AND PROCESSING ASSETS

     As part of the Company's announced action plan in 1993 to focus on its core
utility business,  the Company, in 1994, entered into an agreement with Williams
for the  sale of  substantially  all of the  assets  of  Gathering  Company  and
Processing Company and for the sale of Northwest and Southeast gas gathering and
processing facilities of the Company.

     The sales transaction  provides for three 10-year  contracts,  each with an
option to renew for an additional  5-year term, with Williams for  competitively
priced  gathering  and  processing  services.  The purchase  and sale  agreement
contains   contractual   requirements   for  the  Company  to  address   various
environmental deficiencies identified as retained liabilities.  It also contains
environmental  representations  and  warranties and  indemnification  provisions
whereby the Company  indemnifies  Williams for a five-year  period after closing
for breaches of the  environmental  representations  and  warranties and against
third party claims to a maximum of $10.6  million.  After the $10.6  million cap
has  been  reached,  or  after  the  expiration  of the  five-year  post-closing
indemnification period,  whichever comes first, Williams indemnifies the Company
against further  environmental  expenditures  related to the properties sold. On
June 30, 1995,  following  NMPUC  approval,  the Company and Williams closed the
sale of the assets. As a result,  the Company and its gas subsidiaries  received
$154 million from Williams and recognized an after-tax gain of $12.8 million, or
31 cents per share.  Under the NMPUC approval,  the Company recorded a liability
of approximately $35 million,  representing an estimate of a portion of the gain
resulting from the sale,  which will be credited to the Company's gas customers'
bills over five years.  After  completion  of the fifth year,  the amount of the
gain  will be  recalculated  to  reflect  actual  expenses  associated  with the
transaction  which were  appropriately  and legitimately  incurred.  Such amount
should include amounts  expended to indemnify  Williams as described  above. Any
resulting  differences  will be refunded or billed to customers  over a one year
period.

                                       30

<PAGE>
     As a result of the gas assets  sales,  the  operations of the Company's two
wholly-owned gas subsidiaries,  Gathering Company and Processing  Company,  have
been substantially discontinued, effective June 30, 1995.

ENVIRONMENTAL ISSUES

     The Company is  committed to complying  with all  applicable  environmental
regulations  in a responsible  manner.  Environmental  issues have presented and
will  continue to present a challenge to the Company.  The Company has evaluated
the potential impacts of the following environmental issues and believes,  after
consideration  of  established  reserves,  that the  ultimate  outcome  of these
environmental  issues will not have a material  adverse  effect on the Company's
financial condition or results of operations.

Electric Operations

Person Station

     The  Company,  in  compliance  with the New Mexico  Environment  Department
Corrective Action Directive, determined that groundwater contamination exists in
the deep and shallow  water  aquifers.  The Company is required to delineate the
extent of the  contamination  and remediate the contaminants in the groundwater.
The extent of the contaminated plume in the deep water aquifer has been assessed
and  results  have been  reported to the NMED.  The  Company  has also  proposed
revised  remedial  options to the NMED. The Company is awaiting a final response
from the NMED.  The  Company's  current  estimate  to  decommission  its retired
fossil-fueled  plants  includes  approximately  $10.9  million to  complete  the
groundwater  remediation  program at Person  Station.  As part of the  financial
assurance  requirement of the Person Station Hazardous Waste Permit, the Company
posted a $5.1 million  performance bond with a trustee.  The remediation program
continues on schedule.

Santa Fe Station

     The  NMED  has  been  conducting  an   investigation   of  the  groundwater
contamination detected beneath the Santa Fe Station site to determine the source
of the  contamination.  The Company has been and is continuing to cooperate with
the NMED site  investigation  pursuant  to a  settlement  agreement  between the
Company and the NMED. In May 1995,  the Company  received a letter from the NMED
indicating that the NMED had made a determination  that Santa Fe Station was the
source  of  gasoline-contaminated  groundwater  at the  site and  vicinity.  The
Company contested the NMED's determination and believes insufficient data exists
to definitely identify the sources of groundwater contamination.  A minimum site
assessment ("MSA") of the two former underground storage tank sites at the Santa
Fe Station site was conducted by the Company under the settlement agreement. The
MSA report indicated that the Santa Fe Station site does not appear to have been
a source of gasoline  contamination.  The MSA report has been  submitted  to the
NMED and is currently pending NMED review.

Albuquerque Electric Service Center

     Trenching  work at the electric  service center  revealed oil  contaminated
soil in an area of the service  center where used oil in drums were stored.  The
trenched  area  bisects a small  portion of the storage  area,  indicating  that
potentially  the area could be underlain  with  contaminated  soil.  The Company
requested  a  laboratory   analysis  on  the  soil  to  determine  the  type  of
contamination.  The Company may be required to assess soil and  groundwater  for
contamination  as well as remediate  extensive  volumes of soil in the area. The
Company currently cannot predict the outcome of the analysis, to what extent the
soil was contaminated or the costs of the remediation, if any.


                                       31

<PAGE>
     In addition,  leaking  underground  fuel lines,  which have been  replaced,
caused soil and  groundwater  contamination  in the  vicinity  of the leak.  The
Company  proposed a quarterly  sampling plan to the NMED for the site.  The NMED
has expressed  concerns  regarding  the  placement of  monitoring  wells and the
relatively  high levels of residual  contamination  remaining in the soil at the
site. Based on the recent analysis of the groundwater sampling, the contaminated
soil  does not  appear to be a  continual  recharge  source  to the  groundwater
contamination.  The  NMED  may  require  additional  monitoring  wells  and soil
remediation work at the site.

Gas Operations

Air Permits

     In 1994, following an environmental audit performed in conjunction with the
Company's  sale of certain gas  assets,  which  audit  brought to light  certain
discrepancies regarding required air permits associated with certain natural gas
facilities,  the  Company  met with the NMED to discuss the nature of the permit
discrepancies and to propose methods and schedules to resolve the discrepancies.

     The Company submitted in 1994 its permit  modification  application for the
Lybrook Gas Processing Plant ("Lybrook"). The Lybrook permit has now been issued
to Williams, the purchaser of the gas assets.

     The Company submitted an air permit  modification  application for the Kutz
Canyon Gas  Processing  Plant  ("Kutz") in the first quarter of 1995. In October
1995,  the Company  received a Notice of  Violation  ("NOV")  from the NMED with
specified corrective actions on the permit discrepancies in the Kutz air permit.
In January 1996,  the Company  accepted a settlement  offer for the NOV from the
NMED in the amount of $15,000.  The Company cannot predict when the final permit
will be issued by the NMED or whether additional requirements will be imposed by
the NMED as conditions for issuance of the permit.

Gas Wellhead Pit Remediation

     The New  Mexico  Oil  Conservation  Commission  ("NMOCC")  issued an order,
effective on January 14, 1993, that affects the gas gathering facilities,  which
were sold to Williams, located in the San Juan Basin in northwestern New Mexico.
The  order  prohibits  the  further  discharge  of  fluids  associated  with the
production of natural gas into unlined  earthen pits in certain  specified areas
of the San Juan Basin.  The order also required the  submission of closure plans
for the closure of pits in which production  fluids were previously  discharged.
The BLM has issued a similar ruling.  The Company has complied with such rulings
and submitted  and received  approval of the pit closure plans from the OCD, the
Energy Minerals and Natural Resources Department, as well as the BLM.

     The Company has received  letters and directives from the OCD directing the
Company to determine if certain unlined  discharge pits have  contributed to the
groundwater  contamination  plumes  that were  identified  at those  sites.  The
Company is currently  assessing the sites in accordance  with the OCD directive.
The  Company  continues  to  assess  unlined  pits in  accordance  with  the OCD
directive and is addressing potential  groundwater  contamination issues as they
arise during the assessment process.

     On March 3, 1995,  the  Jicarilla  Apache  Tribe  ("Jicarilla")  enacted an
ordinance   directing   that  unlined   surface   impoundments   located  within
environmentally  sensitive  areas be remediated and closed by December 1996, and
that all other unlined surface  impoundments on Jicarilla's  lands be remediated
and  closed  by  December   1998.   The   Company  has   received  a  claim  for
indemnification  by Williams for the environmental  work required to comply with
the Jicarilla ordinance. The Company has submitted a closure/remediation plan to
the Jicarilla,  which has been approved,  and the Company anticipates initiating
the remediation  process in the spring of 1996. The costs of remediation will be
charged against the $10.6 million  indemnification cap contained in the purchase


                                       32

<PAGE>
and sale  agreement  between  the  Company and  Williams.  The Company  does not
anticipate that the claim for  indemnification  will have any material impact on
the Company's financial condition or results of operations.

GAS RATE CASE

     On  August  28,  1995,  the  Company  filed a request  for a $13.3  million
increase in its retail natural gas sales and  transportation  rates. NMPUC Staff
and intervenors in the case filed their testimony on January 16, 1996. The Staff
recommended a $2.5 million rate decrease and the AG  recommended a $14.7 million
rate decrease.  The major issues in the case center around the Company's request
to recover certain costs  associated with reservation  fees,  discounts given to
large and industrial  transportation  customers and losses incurred to reacquire
debt. The Company  anticipates  that it will have deferred as regulatory  assets
approximately  $22 million related to these items through July 1, 1996, the date
when rates are anticipated to go into effect. The Company will file its rebuttal
testimony  on  February  23,  1996 and  hearings  will  begin on March 4,  1996.
Although  the Company  cannot  predict the  ultimate  outcome of this case,  the
Company believes that it has meritorious  claims and will vigorously  pursue the
recovery of these assets.

ALBUQUERQUE FRANCHISE ISSUES

     The Company's  non-exclusive  electric  service  franchise with the City of
Albuquerque (the "City") expired in 1992. The franchise  agreement  provided for
the  Company's  use of City  rights-of-way  for  placement  of electric  service
facilities.  The Company provides  service to the area which  contributed 46% of
the Company's total 1995 electric operating revenues. The absence of a franchise
does not change the  Company's  right and  obligation  to serve those  customers
under state law.

     In 1991, the NMPUC issued an order concluding, among other things, that the
City could bid for services to its own facilities  (Albuquerque  municipal loads
generated  approximately  $16.6 million in annual revenue for 1995), but not for
service to other  customers.  However,  the New Mexico  Supreme Court  ("Court")
ruled that a city can  negotiate  rates for its  citizens in addition to its own
facility  uses.  The Court also  ruled that any  contracts  with  utilities  for
electric  rates are a matter of  statewide  concern  and  subject  to  approval,
disapproval or modification by the NMPUC. In addition,  the Court reaffirmed the
NMPUC's  exclusive  power to  designate  providers of utility  service  within a
municipality  and confirmed that municipal  franchises are not licenses to serve
but rather provide access to public rights-of-way.

     During  1992,  representatives  of the  Company  and the City had  numerous
meetings in attempts to resolve the franchise renewal issue. Since that time, no
meetings  have  been  held.  The City  continues  to  maintain  its  options  by
advocating industry restructuring and monitoring the municipalization activities
of the  City  of Las  Cruces.  A  measure  designed  to  start  municipalization
activities  in  Albuquerque  was  defeated  by the  City  Council.  The  Company
continues to collect and pay franchise fees to the City.

PVNGS NUCLEAR DECOMMISSIONING

Decommissioning Costs and Trust Funds

     The Company has a program  for funding its share of  decommissioning  costs
for PVNGS. Under this program,  the Company makes a series of annual deposits to
an  external  trust fund over the  estimated  useful  life of each unit with the
trust funds being invested under a plan which allows the  accumulation  of funds
largely on a tax-deferred  basis through the use of life  insurance  policies on
certain current and former  employees.  The results of the 1995  decommissioning
study indicate that the Company's share of the PVNGS  decommissioning costs will
be  approximately  $145.6  million,  a decrease from $157.8 million based on the
previous 1992 study (both amounts are stated in 1995 dollars).


                                       33

<PAGE>
     The Company has determined that a supplemental  investment  program will be
needed as a result of both cost  increases  identified in the 1992 study and the
lower than  anticipated  performance of the existing  program.  On September 29,
1995, the Company filed a request for  permission  from the NMPUC to establish a
qualified tax advantaged  trust for PVNGS Units 1 and 2. Due to Internal Revenue
Service ("IRS") regulations, PVNGS Unit 3 will remain in a non-qualified trust.

     The  Company,  on February 7, 1996,  filed a motion for interim  relief for
establishment  of a qualified  trust  pending  final NMPUC  action.  The interim
request  was  necessary  in order  to meet  the  March  15  deadline  under  IRS
requirements  for the  qualified  trust to be effective for the current year. On
February 19, 1996, the NMPUC granted this request.

     The market value of the existing trust at the end of 1995 was approximately
$12.4 million,  which includes the cash surrender value of the current insurance
policies.

Decommissioning Costs of Nuclear Power Plants

     In February 1996, the Financial  Accounting Standards Board ("FASB") issued
an Exposure Draft on the  accounting  for closure and removal  costs,  including
decommissioning,  of nuclear power plants.  If current electric utility industry
accounting  practices for nuclear power plant  decommissioning are changed,  the
annual  provision  for  decommissioning  could  increase  relative to 1995,  and
estimated  costs for  decommissioning  could be recorded as a liability  (rather
than as accumulated  depreciation),  with recognition of an increase in the cost
of related  nuclear power plants.  The Company is unable to predict the ultimate
outcome of this project.

PVNGS PROPERTY TAXES

     On June 29, 1990,  an Arizona  state tax law was  enacted,  effective as of
December 31, 1989, which adversely  impacted the Company's earnings in the years
of 1990 through 1995 by approximately $5 million per year,  before income taxes.
On December 20, 1990,  the PVNGS  participants,  including the Company,  filed a
lawsuit in the Arizona Tax Court,  a division of the  Maricopa  County  Superior
Court,  against the Arizona Department of Revenue, the Treasurer of the State of
Arizona,  and various  Arizona  counties,  claiming,  among other  things,  that
portions of the new tax law are  unconstitutional.  In December  1992, the court
granted  summary  judgment to the taxing  authorities,  holding  that the law is
constitutional.  The PVNGS  participants  appealed  this decision to the Arizona
Court of Appeals.  On November 21, 1995,  the Arizona  Court of Appeals ruled in
favor of the PVNGS participants. Due to the significance of this decision, it is
anticipated  that the case will be  further  pursued  through  the  courts.  The
Company cannot currently predict the ultimate outcome of this matter.

EL PASO

     El Paso,  one of the  joint  owners  of PVNGS  and Four  Corners,  has been
operating under Chapter 11 of the Bankruptcy  Code since 1992.  After the failed
merger  transaction with Central and South West Corporation,  in September 1995,
El Paso filed with the  bankruptcy  court a revised  plan  whereby,  among other
things, certain issues would be resolved,  including its assumption of the joint
facilities operating agreements.  The revised plan, as amended, was confirmed by
order of the Bankruptcy  Court on January 9, 1996. The order approves an amended
Assumption and Cure Agreement  between El Paso and all participants at PVNGS. As
a part of its plan, El Paso also assumed agreements at Four Corners and paid all
sums  outstanding  under the  agreements.  In addition,  El Paso assumed various
transmission  agreements  with the  Company.  Currently,  there are no remaining
claims by the Company to be resolved in connection with the bankruptcy.  El Paso
emerged from bankruptcy on February 12, 1996.

ACCOUNTING STANDARDS

SFAS No.  121,  Accounting  for the  Impairment  of  Long-Lived  Assets  and for
Long-Lived Assets to Be Disposed Of

     In March 1995, the FASB issued Statement of Financial  Accounting  Standard
("SFAS") No. 121. This statement  requires  companies to review their long-lived
assets for impairment whenever events or changes in circumstances  indicate that
the  carrying  amount of such assets may not be  recoverable.  SFAS No. 121 also
requires all regulatory  assets,  which must have a high probability of recovery
to be  initially  established,  must  continue  to meet  that  high  probability
standard to avoid being written off. However, if written off, a regulatory asset
can be restored if, through  regulatory  actions,  it again becomes  probable of
recovery.  The adoption of SFAS No. 121 had no impact on the Company's financial
condition or results of operations.

PVNGS -- STEAM GENERATOR TUBES

     APS, as the operating agent of PVNGS,  has encountered tube cracking in the
steam generators and has taken, and will continue to take, remedial actions that
it believes have slowed further tube  degradation.  The steam generator tubes in
each unit continue to be inspected in conjunction with their respective outages.
APS  currently  believes  that the PVNGS steam  generators  in Units 1 and 3 are
capable of operating for their designed life of forty years,  although,  at some
point,  long-term economic  considerations  may warrant  examination of possible
steam generator  replacement.  APS's ongoing  analyses  indicate that it will be
economically  desirable  for APS to replace the Unit 2 steam  generators,  which
have been most affected by tube cracking, in five to ten years. APS expects that
the steam generator  replacement can be accomplished within financial parameters
established before replacement was a consideration. Based on APS's analyses, the
Company  believes that its share of the  replacement  costs (in 1995 dollars and
including  installation  and  replacement  power costs)  would be between  $10.5
million and $17.5 million,  most of which would be incurred after the year 2000.
APS expects that the replacement would be performed in conjunction with a normal
refueling  outage  in order  to  limit  additional  incremental  outage  time to
approximately  50  days.  APS  believes  that  replacement  of the  Unit 2 steam
generators within five to ten years will be economically desirable.  The Company
is evaluating this and other options in regards to this issue.

     All of the PVNGS units were  operating  at full power at December  31, 1995
and are  expected to continue  operating  at full  power,  except for  scheduled
(mid-cycle or refueling) outages.  Last year, PVNGS had three refueling outages,
one for each of the three units.

              MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS

         The management of Public  Service  Company of New Mexico is responsible
for the preparation and presentation of the accompanying  consolidated financial
statements.   The  consolidated  financial  statements  have  been  prepared  in
conformity  with generally  accepted  accounting  principles and include amounts
that are based on informed  estimates  and judgments of  management.  Management
maintains a system of internal accounting controls which it believes is adequate
to provide  reasonable  assurance that assets are safeguarded,  transactions are
executed in accordance with management  authorization  and the financial records
are reliable for preparing the consolidated financial statements.  The system of
internal accounting controls is supported by written policies and procedures, by
a staff of internal  auditors who conduct  comprehensive  internal audits and by
the  selection  and training of  qualified  personnel.  The board of  directors,
through  its audit  committee  comprised  entirely of outside  directors,  meets
periodically with management,  internal  auditors and the Company's  independent
auditors to discuss auditing,  internal control and financial reporting matters.
To  ensure  their  independence,  both the  internal  auditors  and  independent
auditors  have  full and free  access to the audit  committee.  The  independent
auditors,  Arthur Andersen LLP, are engaged to audit the Company's  consolidated
financial statements in accordance with generally accepted auditing standards.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of
  Public Service Company of New Mexico:

We have audited the accompanying  consolidated  balance sheets and statements of
capitalization   of  Public  Service   Company  of  New  Mexico  (a  New  Mexico
corporation)  and subsidiaries as of December 31, 1995 and 1994, and the related
consolidated  statements of earnings (loss),  retained earnings  (deficit),  and
cash flows for each of the three years in the period  ended  December  31, 1995.
These financial  statements are the responsibility of the Company's  management.
Our responsibility is to express an opinion on these financial  statements based
on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position of Public Service Company of New
Mexico and subsidiaries as of December 31, 1995 and 1994, and the results of its
operations  and its cash flows for each of the three  years in the period  ended
December 31, 1995 in conformity with generally accepted accounting principles.

As explained in notes 1 and 7 to the financial statements,  effective January 1,
1993, the Company adopted Statement of Financial  Accounting  Standards No. 106,
Employer's Accounting for Postretirement  Benefits Other Than Pensions,  and No.
109, Accounting for Income Taxes.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        December 31, 1995, 1994 and 1993

(1)     Summary of Significant Accounting Policies

Systems of Accounts

       The Company  maintains its accounts for utility  operations  primarily in
accordance with the uniform systems of accounts prescribed by the Federal Energy
Regulatory  Commission  ("FERC")  and the  National  Association  of  Regulatory
Utility  Commissioners  ("NARUC"),  and adopted by the New Mexico Public Utility
Commission ("NMPUC").

Organization

       Public Service Company of New Mexico (the "Company") is an investor-owned
utility company engaged in the generation,  transmission,  distribution and sale
of electricity.  The Company provides retail electric service to a large area of
north  central New Mexico,  including the cities of  Albuquerque,  Santa Fe, Rio
Rancho,  Las  Vegas,  Belen and  Bernalillo.  The  Company  provides  service to
customers  in the City of  Albuquerque  without  a  franchise  agreement,  which
contributes  approximately  one-half of the Company's  total electric  operating
revenues.  The absence of a franchise  does not change the  Company's  right and
obligation to serve these  customers  under state law. The Company also provides
retail electric  service to Deming in southwestern  New Mexico and to Clayton in
northeastern  New  Mexico.  The  Company is also  engaged  in the  transmission,
distribution and sale of natural gas within the State of New Mexico. The Company
distributes  natural  gas  to  most  of the  major  communities  in New  Mexico,
including Albuquerque and Santa Fe.

Principles of Consolidation

       The consolidated financial statements include the accounts of the Company
and  subsidiaries in which it owns a majority voting  interest.  All significant
intercompany transactions and balances have been eliminated.

Use of Estimates

       The  preparation  of financial  statements in conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the amounts  reported in the financial  statements  and
accompanying notes. Actual recorded amounts could differ from those estimated.

Utility Plant

       Utility  plant,  with the  exception  of Palo  Verde  Nuclear  Generating
Station ("PVNGS") Unit 3 and the Company's purchased 22% beneficial interests in
the PVNGS  Units 1 and 2 leases,  is stated at  original  cost,  which  includes
capitalized  payroll-related  costs  such as taxes,  pension  and  other  fringe
benefits,   administrative   costs  and  an  allowance  for  funds  used  during
construction  ("AFUDC").  Utility plant  includes  certain  electric  assets not
subject to NMPUC  regulation.  The results of operations of such electric assets
are included in operating income.

                        December 31, 1995, 1994 and 1993

(1)    Summary of Significant Accounting Policies (Continued)

       PVNGS Unit 3 and the Company's purchased 22% beneficial  interests in the
PVNGS Units 1 and 2 leases were written down in 1992 and 1993, respectively,  to
their net realizable  value to reflect a permanent  impairment to their original
costs.

       It is Company policy to charge repairs and minor replacements of property
to maintenance  expense and to charge major replacements to utility plant. Gains
or losses resulting from retirements or other dispositions of operating property
in the normal  course of business  are  credited  or charged to the  accumulated
provision for depreciation.

Depreciation and Amortization

       Provision for  depreciation  and amortization of utility plant is made at
annual  straight-line rates approved by the NMPUC. The average rates used are as
follows:


                                          1995           1994          1993
                                      -------------   -----------   -----------

Electric plant........................        3.32%         3.01%         2.98%
Gas plant.............................        3.21%         3.15%         3.12%
Water plant (1).......................           --         2.68%         2.62%
Common plant (2)......................           --         4.94%         4.90%

         (1) Water plant was sold in July 1995 (see note 12).
         (2) As a result of the water plant sale,  common plant was  transferred
to electric plant.

       Effective January 1, 1995,  depreciation rates were revised and include a
provision for the recovery of fossil-fueled plant decommissioning costs approved
by the NMPUC in 1994 (see note 11).

       The  provision  for  depreciation  of  certain  equipment  is  charged to
clearing   accounts  and  subsequently   allocated  to  operating   expenses  or
construction  projects  based  on  the  use of the  equipment.  Depreciation  of
non-utility  property is computed on the straight-line  method.  Amortization of
nuclear fuel is computed based on the units of production method.

Nuclear Decommissioning

       The Company accounts for nuclear decommissioning costs on a straight-line
basis over the estimated  useful life of the facilities.  Such amounts are based
on  the  net  present  value  of  expenditures   estimated  to  be  required  to
decommission the plant.

Fuel and Purchased Power Adjustment Clause ("FPPCAC")

       The Company's  FPPCAC for its retail customers was eliminated in November
1994. A base fuel cost was  incorporated  with the overall rates approved by the
NMPUC. The Company uses the deferral method of accounting for fuel and purchased
power costs for its  firm-requirements  wholesale  customers.  Such  amounts are
reflected in subsequent periods under a FPPCAC approved by the FERC.

(1)    Summary of Significant Accounting Policies (Continued)

Purchased Gas Adjustment Clause ("PGAC")

       The Company uses the deferral method of accounting for gas purchase costs
which are settled in subsequent  periods under gas  adjustment  clauses.  Future
recovery of these costs is subject to approval by the NMPUC.

Amortization of Debt Discount, Premium and Expense

       Discount,  premium and expense  related to the issuance of long-term debt
are amortized over the lives of the respective  issues.  In connection  with the
retirement of long-term debt, such amounts  associated with resources subject to
NMPUC regulation are amortized over the lives of the respective issues.  Amounts
associated  with the  Company's  firm-requirements  wholesale  customers and its
excluded  resources are recognized  immediately as expense or income as they are
incurred.

Income Taxes

       The Company  reports  income tax expense in accordance  with Statement of
Financial  Accounting  Standards ("SFAS") No. 109,  Accounting for Income Taxes.
SFAS No. 109 requires  deferred income taxes for temporary  differences  between
book and tax to be recorded using the liability  method.  Deferred  income taxes
are computed  using the statutory  tax rates  scheduled to be in effect when the
temporary  differences  reverse.  Current NMPUC jurisdictional rates include the
tax effects of the  majority  of these  temporary  differences  (normalization).
Recovery of reversing temporary  differences  previously accounted for under the
flow-through  method  is also  included  in  rates  charged  to  customers.  For
regulated  operations,  any changes in tax rates applied to accumulated deferred
income taxes may not be  immediately  recognized  because of ratemaking  and tax
accounting  provisions  contained  in the Tax  Reform  Act of  1986.  For  items
accorded  flow-through  treatment under NMPUC orders,  deferred income taxes and
the future ratemaking effects of such taxes, as well as corresponding regulatory
assets and liabilities, are recorded in the financial statements.

Accounting for Stock-Based Compensation

       The Company has a stock option plan for certain  selected key  employees.
The Company accounts for this plan under Accounting Principles Board Opinion No.
25,  Accounting for Stock Issued to Employees,  under which no compensation cost
has been recognized (see note 7).

Accounting for the Impairment of Long-Lived  Assets and for Long-Lived Assets to
Be Disposed Of

       In March 1995,  the FASB issued SFAS No.  121.  This  statement  requires
companies to review their  long-lived  assets for impairment  whenever events or
changes in  circumstances  indicate that the carrying  amount of such assets may
not be recoverable. SFAS No. 121 also requires all regulatory assets, which must
have a high probability of recovery to be initially  established,  must continue
to meet that high probability  standard to avoid being written off. However,  if
written off, a regulatory asset can be restored if, through regulatory  actions,
it again  becomes  probable  of  recovery.  The  adoption of SFAS No. 121 had no
impact on the Company's financial condition or results of operations.

(2)    Risks and Uncertainties

Competitive Electric Market

     The  electric  utility  industry  is  currently   undergoing  a  period  of
fundamental  change intended to promote a competitive  environment in the retail
and wholesale energy marketplaces.  Legislators and regulators at both the state
and Federal level are considering whether, and how, to promote competition among
suppliers  of  electricity  and  how to  provide  customers  with  choice  among
suppliers.

     At the Federal level, the FERC promulgated a Notice of Proposed Rule Making
("Mega-NOPR")  in March 1995,  which  proposes to require  utilities to unbundle
their  generation  and   transmission   services  and  to  provide  open  access
transmission.  The  Mega-NOPR  also  supplemented  a prior NOPR  concerning  the
appropriate  treatment of stranded asset costs  associated  with the transition.
Specifically,  the FERC  stated  that  recovery  of  legitimate  and  verifiable
stranded  asset costs is critical to the  successful  transition of the electric
utility industry from a tightly  regulated  cost-of-service  industry to an open
transmission access,  competitively priced industry. The Company in its response
to the Mega-NOPR supported the FERC initiative toward open access  transmission,
but  requested  that all  transmission  asset  owners,  including  municipal and
Federal,  be  subject to the same  requirements  in order to  establish  a level
playing field for all participants in the electric utility industry. The Company
also agreed with the FERC  regarding  the  proposed  recovery of stranded  asset
costs.  A final  decision on the Mega-NOPR is expected in the middle of 1996. On
January 22, 1996, a U.S. Senate bill, "Electricity Competition Act of 1996", was
introduced,  providing a national framework for a competitive  electric industry
by no later than the year 2010. The bill provides for recovery of stranded asset
costs. On February 14, 1996, the Council of Economic Advisors issued an economic
report to Congress in which it  cautioned  that  electric  industry  competition
should ensure competitive  benefits to all power buyers and should not aggravate
pollution  or cause  supply  cuts to the poor.  The report  favors  recovery  of
stranded  asset costs borne by all parties on whose  behalf the  stranded  costs
were   incurred,   including   customers   that   switch  to  other   suppliers.
Representative Dan Schaeffer,  Chairman of the Energy  Subcommittee of the House
of  Commerce  Committee,  has  announced  that he plans to conduct  hearings  on
electric industry  restructuring,  possibly  beginning this summer.  The Company
does not expect  Congressional  legislation  to pass this year,  but does expect
Congressional interest to continue next year.

(2)  Risks and Uncertainties (Continued)

     In November  1995,  after three years of study,  the  Integrated  Water and
Resource  Planning  Committee of the New Mexico State  Legislature (the "IWRPC")
issued a resolution  reporting its findings on the advantages and  disadvantages
of retail  wheeling and  alternative  restructuring  schemes  applicable  to the
electric power industry in New Mexico.  The IWRPC's  recommendation  stated that
any proposed  restructuring  (i) must benefit all ratepayers in the state,  (ii)
must maintain and possibly encourage the financial health and economic viability
of each of the state's utilities,  (iii) must provide for appropriate protection
from unfair or advantaged  competition from utilities or others from outside the
state, and (iv) must share equitably any costs,  including stranded asset costs,
among the  varied  interests  benefitted.  The IWRPC also  recommended  that the
NMPUC, under legislative direction and guidance, should monitor and evaluate the
electric power industry and applicable  market influences and factors and report
its  findings,   conclusions  and   recommendations  to  the  New  Mexico  State
Legislature  for  legislative  approval  and action,  as  necessary,  before any
proposed restructuring may be implemented. The resolution further indicated that
this  continuing  evaluation  was necessary  because of continuing  changes even
though  restructuring  and retail  wheeling  are not  justified or in the public
interest  at this time.  The  Committee  resolution  was  presented  to the full
Legislature as a Senate Joint Memorial.  It was unanimously passed by the Senate
and the House.

     In  November  1995,  the NMPUC  issued a Notice of  Inquiry  regarding  the
restructuring of regulation of the electric utility industry in New Mexico.  The
NMPUC is seeking input on a variety of questions related to competition,  retail
wheeling  and state vs.  Federal  jurisdiction.  The Company in its February 15,
1996 response  stated that it believes that: (i) competition and customer choice
may be beneficial to all affected  interests in New Mexico if done appropriately
and (ii) in order to achieve restructuring,  there must be cooperative state and
Federal action to avoid  prolonged  uncertainty  and  litigation,  as well as to
avert   inconsistent  state  actions  that  would  inhibit  the  development  of
competitive markets and restrict the benefits that they may provide. The Company
proposed  a  five-year  period  to  accomplish  the  transition  to  a  workable
competitive  market.  The Company  also  stated  that it supports  action by the
United  States  Congress  to  clarify   boundaries  between  state  and  Federal
jurisdiction  over the  electric  utility  industry,  and to ensure  that retail
wheeling  can be  implemented  in a manner that  ensures  fair  competition  and
provide utilities the opportunity to recover all stranded asset costs.

     Although it is uncertain as to the ultimate outcome of possible open access
or retail wheeling  initiatives,  the Company will continue to be active at both
the state and Federal levels in the public policy debate on the restructuring of
the  electric  utility  industry.  By working  with  customers,  regulators  and
legislators,  the Company  believes that an agreement  will be reached that will
protect the interests of stockholders as well as offer the potential benefits of
a competitive marketplace to all customers.

(2)  Risks and Uncertainties (Continued)

Uncertainties

     The future  structure of the industry,  the form and timing of  competition
and the method of regulation in a competitive  environment remain uncertain.  If
retail wheeling is implemented,  it is possible that, based on other deregulated
industries' experiences,  retail energy prices could drop significantly.  Should
that  be  the  case,  the  value  of  a  utility's   assets  could  be  affected
significantly in the transition to a more competitive  market from a traditional
rate regulated environment.  Currently, the Company's generation costs are above
those of  neighboring  utilities to the north and east of the Company's  service
territory.

     The Company believes that the 1994 electric retail rate reduction  improved
its competitive  position,  but recognizes that lower cost producers may have an
advantage if the  regulatory  framework  changes  significantly  towards  retail
wheeling.   The  Company's  owned  nuclear   capacity  is  currently  valued  at
approximately  $900 per KW. If the  Company  were  required  to value its leased
nuclear  capacity at the same level as its owned nuclear  capacity,  it would be
valued at approximately $180 million versus approximately $560 million. If there
were no provision for the recovery of stranded asset costs, the Company would be
required to charge against earnings approximately $380 million.

Preparation for the Changes

     In order to mitigate the exposures  associated with a competitive  electric
market and transition into this changing  environment,  the Company  established
the  following  strategic  plan in 1995:  (i) secure  financial  flexibility  by
retiring debt,  (ii) control  operation and  maintenance  costs,  (iii) focus on
maximizing shareholder value for the nuclear generation assets, and (iv) develop
new business  opportunities  in the energy and utility  related area. As part of
this plan, the Company restructured its operation into four distinctive business
units, each targeted at a specific segment of its customer base with emphasis on
being  more  customer  oriented  and  responsive  to  the  changing  competitive
environment. The four business units are as follows: (i) Electric Services, (ii)
Gas Services, (iii) Bulk Power Services and (iv) Energy Services.

     In order to maximize value of the nuclear  generation assets, the Company's
board of directors  (the  "Board"),  at its December 5, 1995 meeting,  confirmed
that it is in the best interest of the Company at this time to focus its efforts
and resources on maximizing shareholder value from PVNGS as an asset (leased and
owned) of the Company rather than  disposing of it. Growth in the region,  rapid
growth  in  the  Company's  own  local  service  territory  and  the  continuous
improvement in the operating performance of the plant this year were all factors
in the change of approach. The Board stated that the Company no longer considers
it to be a goal to dispose of its interests in PVNGS.

(2)  Risks and Uncertainties (Continued)

     On December 30, 1994,  the Company filed a petition for  declaratory  order
with the NMPUC. In the petition,  the Company  requested,  among other things, a
declaratory  order that its  corporate  reorganization  into four main  business
units was in compliance with NMPUC regulations and previous orders and otherwise
lawful.  Subsequently,  on June 23, 1995, the Company filed an  application  for
authorization for the creation of three wholly-owned subsidiaries to: (i) manage
and  operate  water  and  wastewater  systems,  (ii)  pursue  energy  marketing,
alternative  fuel vehicle  services and energy  management  services;  and (iii)
pursue utility  management  services and related energy management  services for
federal  installations  and  large  commercial  customers.  The  Company  sought
approval to invest a maximum of $50 million in the three  subsidiaries over time
and to enter into  reciprocal  loan  agreements for up to $30 million with these
subsidiaries.  The NMPUC Staff filed a motion on September  20, 1995 to have the
case dismissed.  On January 31, 1996, the hearing examiner  assigned to the case
recommended  that the NMPUC deny the Staff's  motion.  On February 5, 1996,  the
Staff filed a motion seeking to have the Company file an immediate report on its
non-regulated  activities being conducted without prior NMPUC approval;  explain
why NMPUC  approval is not  required;  and explain why  sanctions  should not be
considered if approval is required.  On February 19, 1996, the Company filed its
response  describing its non-utility (energy and utility related) activities and
presenting the legal  authority  demonstrating  that prior NMPUC approval is not
required.  The Company  currently  cannot  predict the ultimate  outcome of this
proceeding but intends to vigorously defend against any allegation that it is in
violation of any legal requirements.

     The Company is subject to the  provisions of SFAS No. 71,  "Accounting  for
the Effects of Certain  Types of  Regulation"  on  operations  regulated  by the
NMPUC.  Regulatory  assets  represent  probable  future  revenue to the  Company
associated with certain costs which will be recovered from customers through the
ratemaking process.  Regulatory liabilities represent probable future reductions
in revenues associated with amounts that are to be credited to customers through
the  ratemaking  process.  Regulatory  assets and  liabilities  reflected in the
Consolidated Balance Sheets as of December 31, relate to the following:

becomes  no longer  subject  to the  provisions  of SFAS No.  71, a write off of
related regulatory assets and liabilities would be required, unless some form of
transition  cost  recovery  (refund)  continues  through rates  established  and
collected for the Company's remaining regulated operations.

Common Stock

       The number of authorized  shares of common stock with par value of $5 per
share is 80 million shares.

       The Company has not declared  dividends on its common stock since January
1989 and  anticipates  announcing a dividend plan sometime before the end of the
second quarter of 1996. The Company's  board of directors  reviews the Company's
dividend  policy on a continuing  basis.  The resumption of common  dividends is
dependent upon a number of factors including earnings and financial condition of
the  Company  and market  conditions.  The  deficit  in  retained  earnings  was
eliminated during 1995.

Cumulative Preferred Stock

       The  number of  authorized  shares of  cumulative  preferred  stock is 10
million  shares.  The Company's  restated  articles of  incorporation  limit the
amount  of  preferred  stock  which  may be  issued.  The  earnings  test in the
Company's  restated articles of incorporation  currently allows for the issuance
of preferred stock.

       On August 7, 1995, the Company redeemed, at par, all of its 8.48% Series,
8.80% Series and 8.75% Series of cumulative  preferred  stock  outstanding as of
July 6, 1995. The redemption  price of $64 million  included  accrued  dividends
through the redemption date.

Long-Term Debt

       Substantially  all utility plant is pledged to secure the Company's first
mortgage  bonds.  A portion of certain series of long-term debt will be redeemed
serially  prior to their due dates.  The issuance of first mortgage bonds by the
Company is subject to earnings coverage and bondable property  provisions of the
Company's first mortgage  indenture.  The Company also has the capability  under
the  mortgage  indenture to issue first  mortgage  bonds on the basis of certain
previously retired bonds and earnings.

       On March 8, 1995, $121 million of PVNGS Lease  Obligation  Bonds ("LOBs")
were retired.  The retired LOBs consisted of $58 million of 10.30% LOBs due 2014
retired  at a price  of 100% of par and $63  million  of  10.15%  LOBs  due 2016
retired at a price of 97.8% of par. Additionally,  $4.4 million and $4.8 million
of LOBs due 1996 and 1997 at interest  rates of 9.125% and 8.95%,  respectively,
were retired at par on March 22, 1995. In  conjunction  with these  retirements,
the Company wrote off $1.5 million of net costs  related to these  transactions.
The  retirement of the LOBs,  which were the Company's  highest cost debt,  will
save the Company  approximately  $11 million annually in interest expense over a
five year period.

       The  carrying  amounts  reflected  on  the  consolidated  balance  sheets
approximate  fair value for cash,  temporary  investments,  and  receivables and
payables due to the short period of maturity.

       At December 31, 1995,  the Company had a $100 million  secured  revolving
credit facility (the  "Facility")  with an expiration date of June 30, 1998. The
Company  must pay  commitment  fees of 3/8% per year on the total  amount of the
Facility. The Company also has a $40 million credit facility,  collateralized by
the Company's  electric customer accounts  receivable (the "Accounts  Receivable
Facility")  with an  expiration  date of December 20, 1998. On January 30, 1996,
the Company  requested  NMPUC  approval to increase the capacity of the Accounts
Receivable  Facility up to $100 million by including in the collateral  pool the
Company's gas accounts  receivable and certain  amounts being recovered from gas
customers relating to certain gas contract settlements.  This would increase the
Company's liquidity arrangements up to $211 million from $151 million, including
local lines of credit of $11 million.  As of December  31,  1995,  there were no
borrowings  outstanding under the Facility,  the Accounts Receivable Facility or
any of the local lines of credit.

       Plan assets  consist  primarily of domestic  common  stock,  fixed income
securities and cash equivalents.

       The weighted average discount rate used to measure the projected  benefit
obligation was 7.5% and 8.25% for 1995 and 1994, respectively,  and the expected
long-term  rate of return on plan assets was 8.75% for 1995 and 1994. The health
care  cost  trend  rate  was  8.0%,  7.5%  and 6.0%  for  1995,  1994 and  1993,
respectively.  The  effect  of a 1%  increase  in the  health  care  trend  rate
assumption would increase the accumulated  postretirement  benefit obligation as
of December 31, 1995 by  approximately  $11.8 million and the aggregate  service
and interest  cost  components of net periodic  postretirement  benefit cost for
1995 by approximately $1.2 million. The health care cost trend rate was expected
to decrease to 6.0% by 2010 and to remain at that level thereafter.

       The Company  received NMPUC approval in 1994 for the recovery of the full
accrual amount of Electric  Business Unit's retirees' health care costs expense.
The Company  currently  defers the benefit costs in excess of the  pay-as-you-go
basis  for  PNMGS  ($4.4  million  deferred  as of  December  31,  1995) and has
addressed  the  recovery  of this amount as well as the full  accrual  amount of
retirees'  health care costs related to PNMGS in its general rate case which was
filed in August 1995.

Performance Stock Plan

       In 1993, the Company adopted a nonqualified  stock option plan covering a
group of management  employees.  Options are granted at the fair market value of
the shares on the date of grant. Options granted through December 31, 1995, vest
on June 30, 1996, and have a purchase term of up to 10 years.

Balance at December 31, 1995.......      1,664,500        $11.50 - $17.625

     Options may be exercised  following  vesting as described in the plan.  The
aggregate  maximum  number of options  granted under the current plan during its
five-year time frame is two million shares,  subject to certain adjustments.  As
proposed under an amended plan, all subsequent awards granted after December 31,
1995,  shall vest three  years from the grant date of the award and the  maximum
number of options would be increased to five million shares through December 31,
2000.  This amended plan is subject to  shareholder  approval at the next annual
meeting in April 1996.

Executive Retirement Program

     The Company has an executive  retirement  program for a group of management
employees.  The  program  was  intended  to  attract,  motivate  and  retain key
management  employees.  The  Company's  projected  benefit  obligation  for this
program,  as of December 31, 1995, was $18.5 million,  of which the  accumulated
and vested benefit  obligation  was $17.6 million.  As of December 31, 1995, the
Company has recognized an additional liability of $1.6 million for the amount of
unfunded  accumulated  benefits  in excess of  accrued  pension  costs.  The net
periodic pension cost for 1995, 1994 and 1993 was $2.0 million, $2.2 million and
$2.1 million,  respectively.  In 1989,  the Company  established  an irrevocable
grantor trust in connection  with the executive  retirement  program.  Under the
terms of the trust,  the Company may, but is not obligated to,  provide funds to
the trust,  which was  established  with an  independent  trustee,  to aid it in
meeting its obligations under such program. Funds in the amount of approximately
$10.5  million (fair market value of $13.0  million) are presently in trust.  No
additional funds have been provided to the trust since 1989.

(8)    Construction Program and Jointly-Owned Plants

     It is estimated that the Company's construction  expenditures for 1996 will
be approximately $123 million, including expenditures on jointly-owned projects.
The Company's  proportionate  share of expenses for the jointly-owned  plants is
included in operating expenses in the consolidated statements of earnings.

San Juan Generating Station ("SJGS")

       The Company  operates and jointly owns SJGS.  At December 31, 1995,  SJGS
Units 1 and 2 are  owned  on a 50%  shared  basis  with  Tucson  Electric  Power
Company, Unit 3 is owned 50% by the Company, 41.8% by Southern California Public
Power Authority and 8.2% by Century Power Corporation ("Century").  Century sold
its  remaining   8.2%  interest  to  Tri-State   Generation   and   Transmission
Association,  Inc. Unit 4 is owned 38.457% by the Company, 8.475% by the City of
Farmington, 28.8% by M-S-R Public Power Agency, a California public power agency
("M-S-R"),  7.2% by the  County of Los  Alamos,  10.04% by the City of  Anaheim,
California and 7.028% by Utah Associated Municipal Power Systems.

Palo Verde Nuclear Generating Station

       The Company has a 10.2% interest in PVNGS. Commercial operation commenced
in 1986 for Unit 1 and Unit 2 and 1988 for Unit 3. In 1985 and 1986, the Company
completed sale and leaseback transactions for its undivided interests in Units 1
and 2 and certain related common facilities.

       In  1992,  the  Company  purchased  approximately  22% of the  beneficial
interests  in  PVNGS  Units 1 and 2  leases  for  approximately  $17.5  million,
recording  $158.3 million as utility plant and $140.8 million as long-term debt.
In 1993,  such utility  plant was written down to $46.7  million in  conjunction
with the electric retail rate reduction.

(8)    Construction Program and Jointly-Owned Plants (Continued)

       The PVNGS  participants  have  insurance  for public  liability  payments
resulting  from  nuclear  energy  hazards to the full limit of  liability  under
Federal law. This potential  liability is covered by primary liability insurance
provided by commercial  insurance carriers in the amount of $200 million and the
balance by an  industry  wide  retrospective  assessment  program.  The  maximum
assessment per reactor under the  retrospective  rating program for each nuclear
incident  occurring  at  any  nuclear  power  plant  in  the  United  States  is
approximately  $79.3  million,  subject to an annual  limit of $10  million  per
incident.  Based upon the Company's 10.2% interest in the three PVNGS units, the
Company's  maximum  potential  assessment  per incident is  approximately  $24.3
million,  with an annual  payment  limitation of $3 million.  The insureds under
this liability insurance include the PVNGS participants and "any other person or
organization with respect to his legal  responsibility  for damage caused by the
nuclear energy hazard".

       The PVNGS participants  maintain  "all-risk"  (including nuclear hazards)
insurance for nuclear  property damage to, and  decontamination  of, property at
PVNGS in the aggregate  amount of  approximately  $2.75 billion as of January 1,
1996, a substantial  portion of which must first be applied to stabilization and
decontamination. The Company has also secured insurance against a portion of the
increased  cost  of  generation  or  purchased   power  resulting  from  certain
accidental  outages of any of the three PVNGS  units if such  outage  exceeds 21
weeks.

       The Company has a program for funding its share of decommissioning  costs
for PVNGS. Under this program,  the Company makes a series of annual deposits to
an  external  trust over the  estimated  useful life of each unit with the trust
funds being invested under a plan which allows the accumulation of funds largely
on a tax-deferred  basis through the use of life  insurance  policies on certain
current  and former  employees.  The results of the 1995  decommissioning  study
indicate that the  Company's  share of the PVNGS  decommissioning  costs will be
approximately  $145.6  million,  a decrease  from  $157.8  million  based on the
previous 1992 study (both amounts are stated in 1995 dollars).

       The Company has determined that a supplemental investment program will be
needed as a result of both cost  increases  identified in the 1992 study and the
lower than  anticipated  performance of the existing  program.  On September 29,
1995, the Company filed a request for  permission  from the NMPUC to establish a
qualified tax advantaged  trust for PVNGS Units 1 and 2. Due to Internal Revenue
Service ("IRS") regulations, PVNGS Unit 3 will remain in a non-qualified trust.

       The Company,  on February 7, 1996,  filed a motion for interim relief for
establishment  of a qualified  trust  pending  final NMPUC  action.  The interim
request  was  necessary  in order  to meet  the  March  15  deadline  under  IRS
requirements  for the  qualified  trust to be effective for the current year. On
February 19, 1996, the NMPUC granted this request.

       The  market  value  of  the  existing  trust  at  the  end  of  1995  was
approximately  $12.4 million,  which  includes the cash  surrender  value of the
current insurance policies.

(9)    Long-Term Power Contracts and Franchises

       The  Company had two  long-term  contracts  for the  purchase of electric
power. Under a contract with M-S-R, which expired in early 1995, the Company was
obligated to pay certain minimum amounts and a variable  component  representing
the  expenses  associated  with the  energy  purchased  and debt  service  costs
associated  with  capital  improvements.  Total  payments  under  this  contract
amounted to approximately  $14 million for 1995 and $42 million in each year for
1994 and 1993.

       The Company has a long-term  contract with  Southwestern  Public  Service
Company  ("SPS") for up to 200 MW of  interruptible  power from May 1995 through
May 2011.  Total payments under this contract  amounted to  approximately  $12.1
million in 1995.  Minimum  payments under the contract  amount to  approximately
$14.0  million for 1996 and 1997.  In addition,  the Company will be required to
pay for any energy purchased under the contract.  The amount of minimum payments
for future  years will  depend on whether the  Company  exercises  its option to
reduce its purchase  obligations  under the contract.  The Company provided such
notice in 1995 to reduce the purchase by 25 MW in 1999.

(10)   Lease Commitments

       The Company  classifies its leases in accordance with generally  accepted
accounting principles.  The Company leases Units 1 and 2 of PVNGS,  transmission
facilities,  office  buildings and other equipment under operating  leases.  The
lease expense for PVNGS is $66.3 million per year over base lease terms expiring
in 2015 and 2016.  Prior to 1992,  the  aggregate  lease  expense  for the PVNGS
leases was $84.6  million  per year over the base  lease  terms;  however,  this
amount was  reduced  by the  purchase  of  approximately  22% of the  beneficial
interests  in the PVNGS  Units 1 and 2 leases  (see note 8).  Each  PVNGS  lease
contains  renewal and fair market value purchase  options at the end of the base
lease term.

       Future  minimum  operating  lease payments (in thousands) at December 31,
1995 are:


1996................................................  $      77,926
1997................................................         77,674
1998................................................         77,563
1999................................................         77,268

                                                      -------------
   Total minimum lease payments.....................  $   1,490,402
                                                      =============


       Operating lease expense, inclusive of PVNGS leases, was approximately $80
million  in 1995,  $79.1  million in 1994 and $80.6  million in 1993.  Aggregate
minimum payments to be received in future periods under noncancelable  subleases
are approximately $7.2 million.

(11)   Environmental Issues and Fossil-Fueled Plant Decommissioning Costs

       The Company is committed to complying with all  applicable  environmental
regulations  in a responsible  manner.  Environmental  issues have presented and
will  continue to present a challenge to the Company.  The Company has evaluated
the potential impacts of the following environmental issues and believes,  after
consideration  of  established  reserves,  that the  ultimate  outcome  of these
environmental  issues will not have a material  adverse  effect on the Company's
financial condition or results of operations.

Electric Operations

Person Station

       The Company,  in compliance  with the New Mexico  Environment  Department
("NMED") Corrective Action Directive,  determined that groundwater contamination
exists in the deep and  shallow  water  aquifers.  The  Company is  required  to
delineate the extent of the  contamination and remediate the contaminants in the
groundwater.  The extent of the contaminated plume in the deep water aquifer has
been assessed and results have been  reported to the NMED.  The Company has also
proposed  revised  remedial options to the NMED. The Company is awaiting a final
response  from the NMED.  The Company's  current  estimate to  decommission  its
retired  fossil-fueled  plants includes  approximately $10.9 million to complete
the groundwater  remediation program at Person Station. As part of the financial
assurance  requirement of the Person Station Hazardous Waste Permit, the Company
posted a $5.1 million  performance bond with a trustee.  The remediation program
continues on schedule.

Santa Fe Station

       The  NMED  has  been  conducting  an  investigation  of  the  groundwater
contamination detected beneath the Santa Fe Station site to determine the source
of the  contamination.  The Company has been and is continuing to cooperate with
the NMED site  investigation  pursuant  to a  settlement  agreement  between the
Company and the NMED. In May 1995,  the Company  received a letter from the NMED
indicating that the NMED had made a determination  that Santa Fe Station was the
source  of  gasoline-contaminated  groundwater  at the  site and  vicinity.  The
Company contested the NMED's determination and believes insufficient data exists
to definitely identify the sources of groundwater contamination.  A minimum site
assessment ("MSA") of the two former underground storage tank sites at the Santa
Fe Station site was conducted by the Company under the settlement agreement. The
MSA report indicated that the Santa Fe Station site does not appear to have been
a source of gasoline  contamination.  The MSA report has been  submitted  to the
NMED and is currently pending NMED review.

Albuquerque Electric Service Center

       Trenching work at the electric  service center revealed oil  contaminated
soil in an area of the service  center where used oil in drums were stored.  The
trenched  area  bisects a small  portion of the storage  area,  indicating  that
potentially  the entire area could be  underlain  with  contaminated  soil.  The
Company  requested a laboratory  analysis on the soil to  determine  the type of
contamination.  The Company may be required to assess soil and  groundwater  for
contamination  as well as remediate  extensive  volumes of soil in the area. The
Company currently cannot predict the outcome of the analysis, to what extent the
soil was contaminated or the costs of the remediation, if any.

       In addition,  leaking fuel lines,  which have been replaced,  caused soil
and groundwater  contamination in the vicinity of the leak. The Company proposed
a  quarterly  sampling  plan to the NMED for the  site.  The NMED has  expressed
concerns  regarding the placement of monitoring  wells and the  relatively  high
levels of residual contamination remaining in the soil at the site. Based on the
recent  analysis of the groundwater  sampling,  the  contaminated  soil does not
appear to be a continual recharge source to the groundwater  contamination.  The
NMED may require  additional  monitoring  wells and soil remediation work at the
site.

Gas Operations

Air Permits

       In 1994,  following an environmental  audit performed in conjunction with
the Company's  sale of certain gas assets,  which audit brought to light certain
discrepancies regarding required air permits associated with certain natural gas
facilities,  the  Company  met with the NMED to discuss the nature of the permit
discrepancies and to propose methods and schedules to resolve the discrepancies.

       The Company submitted in 1994 its permit modification application for the
Lybrook Gas Processing Plant ("Lybrook"). The Lybrook permit has now been issued
to Williams Gas  Processing-Blanco,  Inc.("Williams"),  the purchaser of the gas
assets.

       The Company submitted an air permit modification application for the Kutz
Canyon Gas  Processing  Plant  ("Kutz") in the first quarter of 1995. In October
1995,  the Company  received a Notice of  Violation  ("NOV")  from the NMED with
specified corrective actions on the permit discrepancies in the Kutz air permit.
In January 1996,  the Company  accepted a settlement  offer for the NOV from the
NMED in the amount of $15,000.  The Company cannot predict when the final permit
will be issued by the NMED or whether additional requirements will be imposed by
the NMED as conditions for issuance of the permit.

Gas Wellhead Pit Remediation

       The New Mexico Oil  Conservation  Commission  ("NMOCC")  issued an order,
effective on January 14, 1993, that affects the gas gathering facilities,  which
were sold to Williams, located in the San Juan Basin in northwestern New Mexico.
The  order  prohibits  the  further  discharge  of  fluids  associated  with the
production of natural gas into unlined  earthen pits in certain  specified areas
of the San Juan Basin.  The order also required the  submission of closure plans
for the closure of pits in which production  fluids were previously  discharged.
The Bureau of Land Management  ("BLM") has issued a similar ruling.  The Company
has complied with such rulings and  submitted  and received  approval of the pit
closure plans from the New Mexico Oil Conservation  Division ("OCD"), the Energy
Minerals and Natural Resources Department, as well as the BLM.

       The Company has received  letters and  directives  from the OCD directing
the Company to determine if certain unlined  discharge pits have  contributed to
the groundwater  contamination  plumes that were identified at those sites.  The
Company is currently  assessing the sites in accordance  with the OCD directive.
The  Company  continues  to  assess  unlined  pits in  accordance  with  the OCD
directive and is addressing potential  groundwater  contamination issues as they
arise during the assessment process.

       On March 3, 1995,  the Jicarilla  Apache Tribe  ("Jicarilla")  enacted an
ordinance   directing   that  unlined   surface   impoundments   located  within
environmentally  sensitive  areas be remediated and closed by December 1996, and
that all other unlined surface  impoundments on Jicarilla's  lands be remediated
and  closed  by  December   1998.   The   Company  has   received  a  claim  for
indemnification  by Williams for the environmental  work required to comply with
the Jicarilla ordinance. The Company has submitted a closure/remediation plan to
the Jicarilla,  which has been approved,  and the Company anticipates initiating
the remediation  process in the spring of 1996. The costs of remediation will be
charged against the $10.6 million  indemnification cap contained in the purchase
and sale  agreement  between the Company and Williams (see note 12). The Company
does not anticipate  that the claim for  indemnification  will have any material
impact on the Company's financial condition or results of operations.

Fossil-Fueled Plant Decommissioning Costs

       The  Company's  six owned or  partially  owned,  in service and  retired,
fossil-fueled   generating  stations  are  expected  to  incur  dismantling  and
reclamation   costs  as  they  are   decommissioned.   The  Company's  share  of
decommissioning  costs  for  all of its  fossil-fueled  generating  stations  is
projected to be  approximately  $141 million  stated in 1995 dollars,  including
approximately  $24.0 million (of which $12.1 million has already been  expended)
for Person, Prager and Santa Fe Stations which have been retired.

       The Company is currently recovering estimated  decommissioning costs from
NMPUC retail customers through its depreciation rates.  Depreciation amounts for
the retired generating units are not being recovered.

(12)   Asset Sales

Sale of Sangre de Cristo Water Company

       In  February  1994,  the  Company  and the City of Santa Fe (the  "City")
executed a purchase and sale agreement for the Company's water division, subject
to NMPUC approval. On May 22, 1995, the NMPUC issued a final order approving the
sale. On July 3, 1995, the closing of the sale was finalized.  As a result,  the
Company  received  $51.2  million  (exclusive of current  assets netted  against
current  liabilities)  from the  sale and  recorded  an  after-tax  gain of $6.4
million, or 15 cents per share. Pursuant to the purchase and sale agreement, the
Company,  through its Energy  Services Unit,  will continue to operate the water
utility up to four years for a fee under a contract with the City.

Sale of Gas Gathering and Processing Assets

       As part of the  Company's  announced  action plan in 1993 to focus on its
core utility  business,  the Company,  in 1994,  entered into an agreement  with
Williams for the sale of  substantially  all of the assets of Gathering  Company
and Processing Company and for the sale of Northwest and Southeast gas gathering
and processing facilities of the Company.

       The sales transaction provides for three 10-year contracts,  each with an
option to renew for an additional  5-year term, with Williams for  competitively
priced  gathering  and  processing  services.  The purchase  and sale  agreement
contains   contractual   requirements   for  the  Company  to  address   various
environmental deficiencies identified as retained liabilities.  It also contains
environmental  representations  and  warranties and  indemnification  provisions
whereby the Company  indemnifies  Williams for a five-year  period after closing
for breaches of the  environmental  representations  and  warranties and against
third party claims to a maximum of $10.6  million.  After the $10.6  million cap
has  been  reached,  or  after  the  expiration  of the  five-year  post-closing
indemnification period,  whichever comes first, Williams indemnifies the Company
against further  environmental  expenditures  related to the properties sold. On
June 30, 1995,  following  NMPUC  approval,  the Company and Williams closed the
sale of the assets. As a result,  the Company and its gas subsidiaries  received
$154 million from Williams and recognized an after-tax gain of $12.8 million, or
31 cents per share.  Under the NMPUC approval,  the Company recorded a liability
of approximately $35 million,  representing an estimate of a portion of the gain
resulting from the sale,  which will be credited to the Company's gas customers'
bills over five years.  After  completion  of the fifth year,  the amount of the
gain  will be  recalculated  to  reflect  actual  expenses  associated  with the
transaction  which were  appropriately  and legitimately  incurred.  Such amount
should include amounts  expended to indemnify  Williams as described  above. Any
resulting  differences  will be refunded or billed to customers  over a one year
period.

       As a result of the gas assets sales,  the operations of the Company's two
wholly-owned gas subsidiaries,  Gathering Company and Processing  Company,  have
been substantially discontinued, effective June 30, 1995.

                         AMENDMENT AND SUPPLEMENT NO. 1

                                       TO

                      SUPPLEMENTAL AND ADDITIONAL OF LEASE


 1.      PARTIES:
         The Parties to this Amendment and Supplement No. 1 to Supplemental  and
         Additional  Indenture of Lease  (hereinafter  referred to as "Amendment
         No. 1") are THE NAVAJO  TRIBE OF  INDIANS,  acting  through  the Navajo
         Tribal  Council and its  chairman for and on behalf of the Navajo Tribe
         of Indians  (hereinafter)  referred to as the "Tribe"),  as Lessor, and
         ARIZONA  PUBLIC  SERVICE  COMPANY,  EL PASO  ELECTRIC  COMPANY,  PUBLIC
         SERVICE  COMPANY  OF  NEW  MEXICO,  SALT  RIVER  PROJECT   AGRICULTURAL
         IMPROVEMENT AND POWER DISTRICT, SOUTHERN CALIFORNIA EDISON COMPANY, and
         TUCSON ELECTRIC POWER COMPANY,  formerly Tucson Gas & Electric  company
         (hereinafter collectively,  together with their successors and assigns,
         referred  to as  "Lessees,"  and singly  referred to as  "Lessee"),  as
         Lessees.

 2.      RECITALS:
         The Parties are entering into this Amendment No. 1 with reference to 
         the following facts, among others:
         2.1   Effective July 6, 1966, the Parties entered into the Supplemental


                                      - 1 -

<PAGE>



               and Additional  Indenture of Lease ("Supplemental Lease"), which
               among  other  things  amended the  Amended  Original  Lease in
               certain  respects  and further  granted  the  Lessees  certain
               leasehold  rights to  construct,  reconstruct,  use,  operate,
               maintain, locate, and remove the Four Corners Project.
         2.2   Since the  Supplemental  Lease was signed in 1966, a number of
               matters have arisen which were not addressed therein or which,
               if addressed,  require  modifications  to the Lease and to the
               coal lease  between  the Tribe and Utah Mining (now named Utah
               International,  Inc.),  the coal  supplier to the Four Corners
               Project,  in order to satisfy the purposes and  objectives  of
               the Parties.
         2.3   Among the more important  modifications from the Tribe's point
               of view is a substantial  increase in the royalties payable on
               coal mined by Utah Mining,  which  eventually will be borne by
               the   Lessees   and   their   customers,    thereby   creating
               consideration to the Tribe for additional  benefits  conferred
               on Lessees by this Amendment No. 1.
         2.4   The Parties desire through this Amendment No. 1 to address and
               resolve to the extent feasible the matters referred to in
               Sections 2.2 and 2.3.
         2.5   The Parties  desire to use in this  Amendment  No. 1 the terms
               defined on Pages 1 through 6 of the Supplemental  Lease in the
               same context as defined and used  therein,  except those terms
               which are amended to read as follows:

<PAGE>

                        "Related   Facilities"  -  Those   facilities  to  be
               constructed  or installed at Four Corners and ultimately to be
               owned by one or more  Lessees  which will serve in  connection
               with the  operation and  maintenance  of any or all of Units 4
               and 5 and the existing three units of the Initial Four Corners
               Plant;
                        "Amended  Original  Plant  Site" - The plant site for
               the existing  three units of the Initial  Four Corners  Plant,
               the area and location of which are shown and  described on the
               plat attached hereto as amended Exhibit 1 hereof, this Amended
               Original Plant Site being a revision (and a diminution) of the
               so  called  "plant  site  area"  leased to  Arizona  under the
               Original  Lease  and  shown  on  Exhibit  A  and  Supplemental
               Exhibits thereto of the Original lease;
                        "New  Plant  Site" - The plant site for Units 4 and 5
               and the switchyard facilities therefor,  the area and location
               of which are shown and described on the plat  attached  hereto
               as Amended  Exhibit 2 hereof.  The New Plant  Site  includes a
               portion of the  so-called  "plant site area" leased to Arizona
               under the Original  Lease,  as well as  additional  contiguous
               lands (the portion heretofore leased to Arizona as part of the
               area  designated  as the "plant site area" under the  Original
               Lease being  deleted  from said "plant site area"  pursuant to
               this Supplement Lease);

                  maintenance  made  necessary by the use by the Lessees of such
                  roads. In the event an access road shall be incorporated  into
                  the  improved  road  system for the State of New Mexico or the
                  Reservation Road System of the Bureau of Indian Affairs, so as
                  to become open for public  use,  the  Lessees  will  surrender
                  their  right-of-way  and  easement  for such  road.  For heavy
                  haulage during periods of construction,  reconstruction,  use,

The Honorable Peterson Zah
Chairman
The Navajo Nation
Window Rock, AZ  86513

Dear Chairman Zah:

         Since  1962,   when  the  Four  Corners   Generating   Station   became
operational,  Arizona Public Service  Company  ("APS") has been dedicated to the
employment of Indians within the plant.  We have made a concerted and consistent
effort to adhere to and advance the concept of "Indian Preference," which can be
demonstrated by the following statistics:

                                       1977           1984
                                    ---------       --------

Total Number of Indian Employees     312 (49%)     696 (65.7%)

         In  addition,  APS has made a  significant  contribution  to the upward
mobility of qualified Indians in numerous  classifications,  as evidenced by the
following information:
                                       1977           1984
                                    ---------       --------

Maintenance Mechanics                 11 (41%)      66 (52%)
Journeyman Classification             20 (19%)     108 (45%)
Auxiliary Operators                   25 (61%)      50 (91%)
Control Operators                      6 (35%)      15 (63%)
First Line Supervisors                 3 (10%)      32 (36%)

         APS is committed to the continued pursuit of preferential employment of
Indians at the Four Corners  Generating  Station  pursuant to the  provisions of
this  Lette  Agreement,  subject  to any  limitations  contained  in  applicable
provisions of the Labor  Agreement in effect between APS and the I.B.E.W.  Local
Union No. 387.  Qualifications  for employment and promotion shall be determined
by APS. In all instances,  qualifications  for positions will be job-related and
nondiscriminatory,  and will be reviewed on an ongoing basis to ensure  validity
and  relevance  of such  qualifications.  A list  of the  current  positions  is
attached as Appendix A.

         In support of this  commitment,  APS proposes the following  program to
enhance the employment status of Indians:

 1.      Employment Preference

          A.      Subject to meeting its established minimum qualifications, APS
                  shall give preference in hiring and promotion to Indians whose
                  qualifications are equal to or better than those of non-Indian
                  Candidates.

          B.      When hiring temporary student employees, preference will be 
                  given to Indians, where qualified.

 2.      Training

         Training   Programs  shall  be  designed  and  implemented  where  cost
         effective  to enable the Four  Corners  Generating  Station to meet its
         manpower  requirements.  With respect to training  courses which may be
         implemented  at the Four  Corners  Generating  Station  in the  future,
         preferential selection will be extended to Indian candidates.

          A.      Training courses APS has conducted at the Four Corners 
                  Generating Station in the past, including the following:

                  Auxiliary Operator             Power Plant Fundamentals
                  Basic Mechanics                Safety Training
                  Control Operator               Supervisory Skills
                  Lubeman                        Management Training
                  Mobile Equipment Training      Water Analyst
                                                 Welder

          B.      With respect to training programs, APS will encourage its 
                  Indian employees to take advantage of such opportunities to 
                  enhance their upward mobility potential.

 3.      Promotions, Transfers and Work Force Reduction

          A.      Performance  Review:  Preference  shall  be  given  to  Indian
                  employees with respect to reductions in force for  performance
                  review  positions  subject  to  job   requirements,   employee
                  qualifications,  and past work  history.  Should a transfer be
                  desired by performance  review  employees and required by APS,
                  preference  shall  be  given  to  the  best  qualified  Indian
                  employee as provided in  Paragraph 1 hereof,  depending on the
                  position into which the transfer is sought.

          B.      Bargaining Unit:  With respect to bargaining unit positions 
                  involved in promotions, transfers, reductions in force and 

                                     - 43 -

                  recalls, seniority establishing by the Labor Agreement will be
                  the deciding factor where  qualifications and physical fitness
                  are substantially equal. However, if not in conflict with such
                  Labor Agreement,  such seniority shall first be applied to the
                  Indian  applicants  or  candidates.  If after  APS has met its
                  preference  obligations  and no Indians  are  available,  then
                  seniority  may be applied among the  non-Indian  applicants or
                  candidates.

 4.      Grievance Procedure:

          A.      Bargaining unit employees will utilize the Grievance Procedure
                  agreed to between APS and I.B.E.W. Local Union No. 387.

          B.      Performance review employees will utilize the established APS 
                  Equity Procedure to resolve grievances.

          C.      APS shall make a good faith  effort to  negotiate  with the
                  I.B.E.W.  to  include  a  provision  in  the  Labor  Agreement
                  requiring the  inclusion of Navajo  employees in the grievance
                  procedure.

 5.      Hiring Notification, Recruiting and Advertising

          A.      When it is  necessary  for APS to hire outside  applicants  to
                  fill job openings,  APS shall utilize Navajo  personnel in its
                  recruitment  process  and shall  provide  notification  to the
                  Navajo  Nation and other  agencies as  indicated  below.  Such
                  notifications  shall  state that  preference  will be given to
                  qualified  American Indians as provided in Paragraph 1 hereof,
                  depending on the position being filled:

                  (i)   Director of the Office of Navajo Labor Relations
                        ("ONLR") in Window Rock, Arizona,

                  (ii)  BIA Employment Assistance Offices in Window Rock and
                        Farmington,

                  (iii) Farmington Inter-Tribal Organization,

                  (iv)  Denver National Indian Employment Resource Center, and

          B.      When  advertising  is  required  for an outside  hire,  the
                  following newspapers will be utilized in addition to others as
                  appropriate:

                  (i)   Navajo Times, Window Rock, Arizona

                  (ii)  Gallup Independent, Gallup, New Mexico

                  (iii) Farmington Daily Times, Farmington, New Mexico

                  (iv)  Lake Powell Chronicle, Page, Arizona.

         C.       APS will  recruit  Indian  candidates  at Northern  Arizona
                  University,  University of Arizona,  Arizona State University,
                  University of New Mexico, and New Mexico State University,  in
                  addition to other educational institutions as appropriate.
 
 6.      Reporting

         The Four  Corners  Power  Plant  will  report  manpower  and  furnish a
         statistical  breakdown  by  race  of  all  new  hires,  promotions  and
         transfers, on a quarterly basis to the ONLR.

 7.      Contractor/Hiring Preference

          A.      Contractors  will be required to agree that Indian  preference
                  will  apply  to  employment  at the  Four  Corners  Generating
                  Station.  Contractors  will be  instructed to notify the Union
                  Hall that Indians,  where  qualified and available,  are to be
                  dispatched before non-Indians.

          B.      Contractors  and APS shall not be responsible  for dispatching
                  of  personnel  by the  Union  Hall,  but only  for the  proper
                  notification  of  the  Union  Hall.   Problems,   if  any,  in
                  dispatching,  shall be addressed  by the Navajo  Nation to the
                  Union Hall,  rather than to  contractors  or APS.  The parties
                  shall use their best  efforts to insure  that job  completion,
                  productivity  and/or costs will not be impacted by dispatching
                  problems.

          C.      Contractors  will be  instructed  by APS to notify the ONLR as
                  soon as  practical  (and to provide  copies of such  notice to
                  APS) of anticipated  manpower  requirements and qualifications
                  needed before placing a call to the Union Hall.

          D.      Contractors will be required to report manpower monthly to
                  ONLR (and provide  copies of such reports to APS),  indicating
                  numbers  of  Indians   and   non-Indians   personnel   by  job
                  classification.

 8.      Contractor/Vendor Preference

         APS shall give  contracting  preference to members of the Navajo Nation
         and Navajo  firms,  certified by the Commerce  Department of the Navajo
         Nation,  in all contract work to be performed on leased lands including
         but not limited to  construction  contracts,  procurement  and personal
         service   contracts,   provided  that  the  requisite   experience  and
         competence to perform such  contractual  work and procure  material and
         equipment of comparable  quality and price in accordance  with standard
         practices in the electric utility industry can be demonstrated. Subject
         to the  foregoing,  where  two or more bids are  received  by APS for a
         given item of contractual  work and where one of such bids is submitted
         by a member of the  Navajo  Nation or a  certified  Navajo  Firm,  such
         contract shall be awarded to such member of the Navajo Nation or Navajo
         firm,  if  their  bids are  equal to or less in price  than the bids of
         non-members or uncertified firms and their  qualifications are equal to
         or better than those of such non-members and firms. More specifically:

          A.      APS shall extend preference to Indian  contractors/vendors and
                  where they are qualified  and/or supply a quality  product and
                  are   evaluated   equal   to   or   better   than   non-Indian
                  contractor/vendor,   the  Indian   contractor/vendor  will  be
                  selected.

          B.      All  contractors/vendors  must be  qualified  by APS before
                  being  placed  on  an  approved  bidders  list.  Qualification
                  includes commercial and financial viability as well as product
                  and/or service quality.

          C.      Potential  contractors/vendors  should be directed to call

10.      Navajo Preference

         In the event the Navajo Nation secures a judgement upholding APS' right
         to  grant  "Navajo"  as  distinguished  from  "Indian"   preference  in
         employment,  APS  agrees  thereafter  to  grant  Navajo  preference  in
         employment in accordance with this Letter Agreement.

11.      Resolution of Disputes Between Parties

         In the  event of a  claimed  breached  of this  Letter  Agreement  or a
         dispute  between the parties arising out of this Letter  Agreement,  at
         the  request  of  either  the  Chairman  of the  Navajo  Nation  or the
         President  of APS,  each of the parties  shall  submit to a  compulsory
         minitrial for the resolution of any such claim or dispute.

         The purpose of the  minitrial is to inform  management  representatives
         for the  parties  of the  theories,  strengths  and  weaknesses  of the
         parties' respective  positions so that the parties may amicably resolve
         the claim or dispute at issue.

          A.      Business  representatives  of each of the parties empowered to
                  decide the issues shall  attend the  minitrial to be conducted
                  for one  business day within 60 days after  written  notice of
                  the claim or  dispute  is  delivered  to the other  party at a
                  mutually  convenient  location.  In  addition,  an  individual
                  mutually  selected by counsel for the parties will attend as a
                  "neutral advisor."

          B.      The fees and expenses of the neutral advisor shall be borne
                  equally by the parties.  Each of the parties  shall  otherwise
                  pay its own costs.

          C.      The  neutral  advisor  shall be  provided  with copies of this
                  Letter  Agreement.  Neither of the  parties  nor anyone on its
                  behalf shall  unilaterally  approach,  contact or  communicate
                  with the neutral advisor after his or her selection.

          D.      Shortly after  appointment of the neutral advisor,  each of
                  the  parties  shall in good faith  attempt to agree to produce
                  documents  requested  by the other party in as  expeditious  a
                  manner as  possible.  The  production  of  documents  shall be
                  subject to the  successful  negotiation  by the  parties of an
                  acceptable arrangement regarding the protection of proprietary
                  or other confidential information. In the event that after the
                  minitrial  the parties  submit their  dispute to litigation as
                  provided in  Subsection  I below,  the  parties  shall in good
                  faith  attempt  to  agree  to  the  entry  of  an  appropriate
                  protective order with respect to the documents produced.

                  The  neutral  advisor  will be  required  to be a party of any
                  confidentiality agreement or protective order.

         E.       Shortly after appointment of the neutral advisor,  mutually
                  agreed  upon  source  material  will  be  jointly  sent to the
                  neutral advisor to assist him/her in familiarizing him/herself
                  with the basic  issues  of the case.  Seven  days  before  the
                  minitrial  is to be  held,  the  parties  shall  exchange  all
                  exhibits they plan to use at the minitrial. Shortly before the
                  scheduled minitrial, if the neutral advisor so suggests and if
                  the parties agree, the neutral advisor may confer jointly with
                  counsel for the parties to resolve any outstanding  procedural
                  questions.  If the neutral  advisor wishes to consult with the
                  parties'  technical  experts on  substantive  issues  prior or
                  after the  meeting,  he/she may outline  the general  areas of
                  inquiry and, on agreement by the parties,  the neutral advisor
                  may  submit  written  questions  to  the  parties'   technical
                  experts.

          F.      Within three (3) days before the minitrial is to be held,  the
                  parties  shall  exchange  and  submit to the  neutral  advisor
                  introductory  statements  which are not to be longer  than ten
                  8-1/2" x 11" double-spaced pages.

          G.      The presentations at the minitrial shall be informal, the time
                  for which  presentations  will be equally  divided between the
                  parties.  Rules of evidence will not apply. While permitted to
                  ask  clarifying  questions,  the  neutral  advisor  shall  not
                  preside  like a judge or  arbitrator,  nor  have the  power to
                  limit the scope or substance  of the  Parties'  presentations.
                  The  presentations  will not be transcribed  or recorded,  but
                  either of the parties may take notes of the proceedings.

          H.      At the  conclusion  of  the  presentations  and to the  extent
                  reasonable,    the   parties   will   make   their    business
                  representatives available for discussions.  If the parties are
                  unable to resolve the  disputes  themselves  based upon a good
                  faith evaluation of the  presentations,  to assist the parties
                  in  further  discussions,  the  neutral  advisor  will  render
                  his/her  comments  orally  on  the  issues.   Thereafter,  the
                  business  representatives  of the  parties  shall  meet and be
                  available for discussions at least once.

          I.      In the event that upon conclusion of the minitrial the parties
                  are unable to  amicably  resolve  their  disputes,  each party
                  shall be free to litigate  such  disputes in the courts of the
                  United  States.  Litigation  shall be  limited  to the  issues
                  considered at the minitrialan shall be conducted to the extent
                  possible on the same terms as the minitrial. The parties agree
                  to waive any applicable statute of limitations for three years
                  following  the  minitrial  defense with respect to  subsequent
                  litigation of these disputes between the parties.

         J.       The  advisory  comments  of the  neutral  advisor  will be
                  inadmissible  for all  purposes  in this or any other  dispute
                  involving the parties.
12.      Term

                                 FACILITY LEASE


                  FACILITY  LEASE,  dated as of December 16,  1985,  between THE
FIRST  NATIONAL  BANK OF BOSTON,  a  national  banking  association,  not in its
individual capacity, but solely as Owner Trustee under a Trust Agreement,  dated
as of December 16, 1985,  with Burnham  Leasing  Corporation  (the Lessor),  and
PUBLIC SERVICE COMPANY OF NEW MEXICO, a New Mexico, corporation (the Lessee).


                              W I T N E S S E T H :

                  WHEREAS,  the Lessor owns the Undivided  Interest and the Real
Property Interest;

                  WHEREAS,  the Lessee  desires to lease the Undivided  Interest
and the Real Property  Interest from the Lessor on the terms and  conditions set
forth herein; and

                  WHEREAS, the Lessor is willing to lease the Undivided Interest
and the Real  Property  Interest to the Lessee on the terms and  conditions  set
forth herein;

                  NOW THEREFORE,  in  consideration of the premises and of other
good and valuable  consideration,  receipt and  sufficiency  of which are hereby
acknowledged, the parties hereto agree as follows:

                  SECTION 1. Definitions.

                  For purposes hereof,  capitalized terms used herein shall have
the  meanings  assigned  to such  terms in  Appendix  A and  Schedule  1 hereto.
References in this  Facility  Lease to sections,  paragraphs  and clauses are to
sections,  paragraphs  and  clauses  in this  Facility  Lease  unless  otherwise
indicated.

                  SECTION  2.  Lease  of  Undivided  Interest;   Term;  Personal
Property.

                  (a) Lease of Undivided Interest. Upon the terms and subject to

                  (b) Term.  The term of this Facility  Lease shall begin on the
Closing Date and shall end on the last day of the Lease Term.

                  (c)  Personal  Property.  It is the express  intention  of the
Lessor and the Lessee that title to the  Undivided  Interest  and every  portion
thereof  is  severed,  and shall be and remain  severed,  from title to the real
estate  constituting  the Real Property  Interest and the PANGS Site. The Lessor
and the Lessee  intend that the Undivided  Interest  shall  constitute  personal
property to the maximum extent permitted by Applicable Law.

                  SECTION 3. Rent; Adjustments to Rent.

                  (a) Basic Rent.  The Lessee shall pay to the Lessor,  as basic
rent  (herein  referred  to as  Basic  Rent)  for the  Undivided  Interest,  the
following amounts:

                           (i) on January 15, 1986, an amount equal to the daily
                  equivalent  of Basic  Rent (set forth in  Schedule  1) payable
                  pursuant to clause (ii) below, from and including December 31,
                  1985 to but excluding  January 15, 1986 plus or minus the Rent
                  Differential, if any, referred to in Section 3(h);

                           (ii) on July 15, 1986 and on each Basic Rent  payment
                  Date  thereafter to and including  January 15, 2015, an amount
                  equal to the  percentage of facility  Cost set forth  opposite
                  such Basic Rent  Payment  Date on Schedule 2 plus or minus the
                  Rent Differential, if any, referred to in Section 3(h); and

                           (iii) if the Lessee shall elect the Renewal  Term, on
                  July 15, 2015 and on each Basic Rent Payment  Date  thereafter
                  during the  Renewal  Term,  an amount  equal to one-half of an
                  amount  determined  by dividing  the amount of all payments of
                  Basic  Rent  payable  with  respect  to the Basic  Lease  Term
                  pursuant  to clause (ii) of this  Section  3(a)  (taking  into
                  account any adjustments pursuant to Sections 3(d) and 3(e) and
                  any increases and decreases pursuant to Section 3(h)), by 58.

If an interest payment on the Initial Series Note (and the Releveraging Note, if
then  outstanding)  shall be due on a date other than a Basic Rent Payment Date,
the Lessee shall pay  additional  Basic Rent on such date equal to such interest

payment and such payment of additional  Basic Rent shall be credited against the
Basic Rent due on the Basic Rent Payment Date next succeeding the date that such
additional Basic Rent shall have been paid.

                  (b)  Supplemental  Rent.  The Lessee  shall pay the  following
amounts (herein referred to as Supplemental Rent):

                           (i) when due or, where no due date is  specified,  on
                  demand,  any amount  (other than Basic Rent,  Casualty  Value,
                  Termination Value and Special Casualty Value) which the Lessee
                  assumes the  obligation to pay or agrees to pay to the Lessor,
                  the Owner Participant,  the Indenture Trustee,  the Collateral
                  Trust Trustee or any Indemnitee under this Facility Lease, any
                  other  Transaction  Document or the Collateral Trust Indenture
                  and any  amount  which the  Lessor is  obligated  to pay under
                  Section 6.9, 7.6 or 8.7 of the Indenture;

                           (ii)  when  due  any  amount  payable   hereunder  as
                  Casualty Value,  Termination  Value or Special Casualty Value,
                  and any  premium or  prepayment  penalty  with  respect to the
                  Notes;

                           (iii) on demand  and in any  event on the Basic  Rent
                  Payment Date next  succeeding  the date such amounts  shall be
                  due  and  payable  hereunder,   to  the  extent  permitted  by
                  Applicable  Law,  interest  (computed  on the  same  basis  as
                  interest on the Notes is  computed)  at a rate per annum equal
                  to (A) the  Overdue  Interest  Rate,  on that  portion  of the
                  payment  of  Basic  Rent or  Supplemental  Rent  distributable
                  pursuant to clause  "first" of Section 5.1 or clause  "second"
                  of  Section  5.3 of the  Indenture  (determined  prior  to the
                  computation  of  interest on overdue  payments  referred to in
                  such clauses), and (B) the Penalty Rate, on the balance of any
                  such payment of Basic Rent or Supplemental Rent (including, in
                  the case of both clause (i) and clause (ii) above, but without
                  limitation,   to  the  extent  permitted  by  Applicable  Law,
                  interest  payable pursuant to this clause (iii)) not paid when
                  due (without regard to any period of grace) for any period for
                  which the same shall be overdue.

The Lessor  shall have all  rights,  powers and  remedies  provided  for in this
Facility  Lease,  at law, in equity  orotherwise,  in the case of non-payment of
Basic Rent or Supplemental Rent.

                  (c) Form of Payment. Subject to Section 11(b), each payment of
Rent under this Facility Lease shall be made in immediately  available  funds no
later than 11:00 a.m., local time at the place of receipt, on the date each such
payment  shall be due and payable  hereunder and shall be paid either (A) in the
case of  payments  other than  Expected  Payments,  to the Lessor at its address
determined in accordance with Section 17, or at such other address as the Lessor
may direct by notice in writing to the  Lessee,  or (B) in the case of  Excepted
Payments,  to such Person as shall be entitled to receive  such  payment at such
address as such  Person may  direct by notice in writing to the  Lessee.  If the
date on which any payment of Rent is due hereunder  shall not be a Business Day,
the  payment  otherwise  due thereon  shall be due and payable on the  preceding
Business  Day,  with the same  force and  effect as if paid on the  normal  date
provided in this Facility Lease.

                  (d)  Adjustments  to Rent.  Basic  Rent and the  schedules  of
Casualty Values,  Termination Values and Special Casualty Values attached hereto
shall be adjusted  (upward or downward) to preserve Net Economic Return if there
is any change in the Code or successor  legislation  enacted by the Ninety-ninth
Congress  or if there is adopted,  promulgated,  issued or  published,  prior to
January 15, 1997, proposed,  temporary or final regulations  resulting therefrom
(regardless of the effective date of such  regulations)  herein referred to as a
Change in Tax Law).  Adjustments  under this paragraph (d) shall be (1) made not
more than once a year and (2) limited in the  aggregate  to the extent,  if any,
necessary such that aggregate  amount of Basic Rent  theretofore  and thereafter
payable  throughout the Basic Lease Term (computed for such purpose only without
regard to any  adjustments  theretofore  made  pursuant to Section  3(e) or 3(h)
shall not be more than 11% upward and 10% downward from the aggregate  amount of
Basic Rent payable throughout the Basic Lease Term (computed as aforesaid) prior
to any  adjustment  theretofore  made pursuant to this Section  3(d);  provided,
however,  that no downward  adjustment  shall be made hereunder unless and until
the aggregate amount of all such downward  adjustments  shall exceed 1% and then
only to the extent such  aggregate  exceeds 1% (resulting in a maximum  downward
adjustment of 10%).  The  foregoing  11% maximum,  10% minimum and 1% "deadband"
limitations  were  determined  on the basis of an assumed  interest  rate on the
Notes  set forth in  Schedule  1  hereunto  and are  subject  to  adjustment  in

connection  with any  refunding  of the Initial  Series Note to provide the same
protection to the Owner  Participant  and the Lessee as provided in the original
calculations thereof by the Owner Participant.

                  The   provisions   of  this   Section  3(d)  to  the  contrary
notwithstanding,  if any  Change in Tax Law is, or  becomes,  applicable  to the
transaction  contemplated  by this Facility Lease in consequence of the transfer
of the Owner  Participant's  beneficial  interest  in the Trust  (whether or not
permitted by Section 15 of the Participation Agreement) or if such Change in Tax
Law would not have been  applicable  to such  transaction  had no such  transfer
occurred,  then no  adjustment  shall be, or be required to be, made pursuant to
this paragraph (d); provided, however, that this sentence shall not apply to the
initial transfer of the Owner  Participants's  beneficial interest to one of its
Affiliates.

                  (e)  Further  Adjustments.  Basic  Rent and the  schedules  of
Casualty Values,  Special Casualty Values and Termination Values attached hereto
shall be adjusted  (upward or downward) to preserve Net Economic Return if there
is (i)  issuance  of the  Releveraging  Note or the Fixed  Rate  Note,  (ii) any
Supplemental  Financing,  (iii) the payment of Transaction Expenses in an amount
which is other than 1.1% of the Purchase Price or (iv) any change in the pricing
assumptions set forth in Schedule 2 to the Participation Agreement.

                  (f)  Computation  of  Adjustments.  Upon the  occurrence of an
event  requiring an adjustment to Basic Rent payable  pursuant to clause (ii) of
Section 3(a), and the schedules of Casualty Values,  Special Casualty Values and
Termination  Values  attached  hereto,  pursuant to paragraph (d) or (e) of this
Section 3, the Owner  Participant  shall  make the  necessary  computations  and
furnish to the  Lessee,  the Loan  Participant,  the  Lessor  and the  Indenture
Trustee the revised amounts and percentages, which amounts and percentages shall
be implemented  upon delivery thereof and effective as of the date of occurrence
of the event requiring such adjustment (taking into account any payment of Basic
Rent already made) and shall remain  effective  until changed in  consequence of
any verification procedure set forth below. Such revised amounts and percentages
shall  be  subject  to  verification  (at the  Lessee's  request)  by the  Owner
Participant's  nationally  recognized  independent public accountants,  in which
case such  accountants  shall  either (i) confirm to the Lessee in writing  that
such  revised  amounts  were  computed on a basis  consistent  with the original


6091.20.2898.47:1
                                              - 5 -

<PAGE>



calculations,  or (ii) compute and provide to the Lessee,  the Lessor, the Owner
Participant,  the Loan Participant and the Indenture Trustee revised amounts and
percentages  which are on such a basis. The revised amounts and percentages,  as
so confirmed or computed if applicable, shall be conclusive and binding upon the
Lessee,  the  Lessor,  the  Owner  Participant,  the  Loan  Participant  and the
Indenture  Trustee.  The  cost of any  such  verification  shall be borne by the
Lessee  unless  such  accountants  shall  require an  adjustment  to the revised
amounts  and  percentages  originally  provided by the Owner  Participant  which
greater than 10% of the adjustment so provided, in which case such cost shall be
divided and paid by the Lessee and the Owner Participant in equal amounts.  Each
adjustment pursuant to paragraph (d) or (e) of this Section 3 may, but need not,
be evidenced by the  execution  and  delivery of a supplement  to this  Facility
Lease  in  form  and  substance   satisfactory  to  the  Lessee  and  the  Owner
Participant,  but shall be effective as provided  herein  without  regard to the
date on  which  such  implement  to  this  Facility  Lease  is so  executed  and
delivered.  Any  adjustment  referred  to in this  Section 3 shall  satisfy  the
provisions of Revenue  Procedure  75-21,  Revenue  Procedure 75-28 and any other
applicable statute,  regulation,  revenue procedure, revenue ruling or technical
information release relating to the subject matter of Revenue Procedure 75-21 or
Revenue Procedure 75-28, but, in the case of any upward adjustment,  shall be no
less than the adjustment otherwise required pursuant to this Section 3.

                  (g)   Sufficiency  of  Basic  Rent  and   Supplemental   Rent.
Notwithstanding   any  other  provision  of  this  Facility  Lease,   any  other
Transaction  Document or any  Financing  Document,  (i) the amount of Basic Rent
payable on each Basic Rent Payment Date shall be at least equal to the aggregate
amount of principal,  premium,  if any, and accrued interest payable on al Notes
then Outstanding and (ii) each payment of Casualty Value, Special Casualty Value
and Termination Value shall in no event be less (when added to all other amounts
required to be paid by the Lessee  under this  Facility  Lease in respect of any
Event of Loss or Deemed Loss Event or termination  of this Facility  Lease) than
an amount  sufficient,  as of the date of payment,  to pay in full the principal
of, and premium, if any, and interest on all Notes Outstanding on and as of such
date of payment (taking into account any assumption of the Notes by the Lessee).

                  (h) Rent  Differential.  So long as the  Initial  Series  Note
shall be  outstanding,  each  installment  of Basic Rent shall be  increased  or
decreased, as the case may be, by the Rent Differential. For purposes hereof,

6091.20.2898.47:1
                                      - 6 -

<PAGE>

Rent Differential  shall mean, as of any Basic Rent Payment Date, the difference
between (i) the aggregate  amount of interest due and payable on each Basic Rent
Payment  Date on the Initial  Series Note (and the  Releveraging  Note,  if then
outstanding), and (ii) the aggregate amount of interest that would have been due
and payable on such Basic Rent  Payment  Date on such Note or Notes if such Note
or Notes had at all times  during the relevant  period borne  interest at a rate
equal to 9.5% per  annum  (computed  on the  basis of a  360-day  year of twelve
30-day months). If, as of any Basic Rent Payment Date, (A) the amount determined
in accordance  with clause (i) of the  immediately  preceding  sentence shall be
greater  than the amount  determined  in  accordance  with  clause  (ii) of such
sentence,  the amount of Basic Rent due on such Basic Rent Payment Date shall be
increased by the Rent Differential,  and (B) the amount determined in accordance
with such clause (ii) shall exceed the amount determined in accordance with such
clause (i),  the amount of Basic Rent due on such Basic Rent  Payment Date shall
be decreased by the Rent Differential.

                  SECTION 4. Net Lease.

                  This Facility Lease (as  originally  executed and as modified,
supplemented and amended from time to time) is a net lease and the Lessee hereby
acknowledges and agrees that the Lessee's  obligation to pay all Rent hereunder,
and  the  rights  of  the  Lessor  in and  to  such  Rent,  shall  be  absolute,
unconditional  and irrevocable and shall not be affected by any circumstances of
any  character,  including,  without  limitation,  (i) any  set-off,  abatement,
counterclaim, suspension, recoupment, reduction, defense or other right or claim
which the  Lessee  may have  against  the  Lessor,  the Owner  Participant,  the
Indenture  Trustee,  the Collateral  Trust Trustee,  the Loan  Participant,  the
Operating  Agent,  any ANPP  Participant,  any  vendor  or  manufacturer  of any
equipment  or assets  included in the  Undivided  Interest,  Unit 1, any Capital
Improvement,  the Real Property Interest,  the PANGS Site, PANGS, or any part of
any thereof,  or any other Person for any reason whatsoever,  (ii) any defect in
or failure of the title  merchantability,  condition,  design,  compliance  with
specifications, operation or fitness for use of all or any part of the Undivided
Interest, Unit 1, any Capital Improvement, the Real Property Interest, the PANGS
Site or PANGS, (iii) any damage to, or removal, abandonment,  shutdown, salvage,
scrapping, requisition, taking, loss, theft or destruction of all or any part of
the  Undivided  Interest,  Unit 1, any Capital  Improvement,  the Real  Property

Interest,  the  PANGS  Site  or  PANGS,  or any  interference,  interruption  or
cessation in the use or possession  thereof or of the Undivided  Interest by the
Lessee or by any other Person (including,  but without limitation, the Operating
Agent or any other ANPP  Participant)  for any reason  whatsoever or of whatever
duration,  (iv) any  restriction,  prevention or curtailment of or  interference
with any use of all or any part of the Undivided  Interest,  Unit 1, any Capital
Improvement,  the Real  Property  Interest,  the PANGS  Site or  PANGS,  (v) any
insolvency,  bankruptcy,  reorganization or similar proceeding by or against the
Lessee, the Lessor, the Owner Participant, the Indenture Trustee, the Collateral
Trust  Trustee,  the Loan  Participant,  the  Operating  Agent,  any other  ANPP
Participant   or  any  other  Person,   (vi)  the   invalidity,   illegality  or
unenforceabilty  of this Facility Lease,  any other  Transaction  Document,  any
Financing  Document,  the ANPP  Participation  Agreement or any other instrument
referred  to herein or therein or any other  infirmity  herein or therein or any
lack of  right,  power  or  authority  of the  Lessor,  the  Lessee,  the  Owner
Participant,  the Indenture  Trustee,  the Collateral  Trust  Trustee,  the Loan
Participant  or any other Person to enter into this  Facility  Lease,  any other
Transaction  Document  or any  Financing  Document,  or any  doctrine  of  force
majeure,  impossibility,  frustration,  failure of consideration, or any similar
legal or equitable doctrine that the Lessee's  obligation to pay Rent is excused
because  the Lessee has not  received  or will not receive the benefit for which
the Lessee bargained, it being the intent of the Lessee to assume all risks from
all causes  whatsoever that the Lessee does not receive such benefit,  (vii) the
breach or failure of any warranty or representation  made in this Facility Lease
or any other Transaction  Document or any Financing  Document by the Lessor, the

Participant or any other Person, (viii) any amendment or other change of, or any
assignment of rights under, this Facility Lease, any other Transaction Document,

or  non-exercise  of any right or remedy under this  Facility  Lease,  any other
Transaction  Document,  any  Financing  Document or any ANPP Project  Agreement,
including,  without limitation,  the exercise of any foreclosure or other remedy
under the Indenture,  the Collateral  Trust Indenture or this Facility Lease, or
the sale of Unit 1, any Capital  Improvement,  the Undivided Interest,  the Real
Property Interest,  the PANGS Site or PANGS, or any part thereof of any interest

therein,  or (ix) any other circumstance or happening  whatsoever whether or not
similar to any of the foregoing.  The Lessee  acknowledges that by conveying the
leasehold estate created by this Facility Lease to the Lessee and by putting the
Lessee in possession of the Undivided  Interest and the Real Property  Interest,
the Lessor has performed all of the Lessor's obligations under and in respect of
this Facility Lease,  except the covenant that the Lessor and Persons acting for
the Lessor will not interfere with the Lessee's quiet enjoyment of the Undivided
Interest and the Real Property Interest. The Lessee hereby waives, to the extent
permitted by  Applicable  Law, any and all rights which it may now have or which
at any time  hereafter  may be conferred  upon it, by statute or  otherwise,  to
terminate,  cancel,  quit or surrender this Facility Lease or to effect or claim
any diminution or reduction of Rent payable by the Lessee  hereunder,  including
without  limitation the provisions of Arizona Revised  Statutes  Section 33-343,

agrees to pay to the Lessor or other Person entitled  thereto an amount equal to
each  installment  of Basic  Rent  and all  Supplemental  Rent at the time  such
payment  would have become due and payable in  accordance  with the terms hereof
had this Facility Lease not been terminated in whole or in part. Each payment of
Rent made by the Lessee  hereunder  shall be final and the Lessee shall not seek
or have any right to recover all or any part of such  payment from the Lessor or
any other  Person for any  reason  whatsoever.  All  covenants,  agreements  and
undertakings  of the Lessee  herein shall be performed at its cost,  expense and
risk  unless  expressly  otherwise  stated.  Nothing in this  Section 4 shall be

Interest or as a guaranty of the Notes.  Any  provisions  of Section 7(b) (2) or
8(c) of the  Participation  Agreement  to the contrary  notwithstanding,  if the
Lessee  shall fail to make any  payment  of Rent to any  Person  when and as due
(taking into account applicable grace periods), such Person shall have the right
at all times, to the exclusion of the ANPP Participants, to demand, collect, sue
for,  enforce  obligations  relating to and otherwise  obtain all amounts due in
respect of such Rent.

thereof has been completed on or prior to the Lease  Termination  Date), and the
Undivided  Interest  shall be free and clear of all Liens (other than  Permitted
Liens  described in clauses (i),  (v) (other than those  arising by,  through or
under the Lessee alone),  (vi),  (vii) (other than as aforesaid),  (viii) (other

agrees  to  indemnify  and hold the  Lessor  (and  each  successor,  assign  and
transferee  thereof)  harmless  against  and  all  obligations  under  the  ANPP
Participation Agreement with respect to contributions or payments required to be

not  exercise its option to renew or purchase as provided in Sections 12 and 13,

efforts  to lease or  dispose  of the  Undivided  Interest  including  using the
Lessee's reasonable efforts to lease or dispose of the Undivided  Interest.  The
Lessor agrees to reimburse  the Lessee for  reasonable  out-of-pocket  costs and
expenses  of the  Lessee  incurred  at the  request  of the  Lessor or the Owner
Participant in connection with such cooperation and such efforts.

Property  Interest or the PANGS Site. As among the Owner  Participant,  the Loan
Participant, the Indenture Trustee, the Collateral Trust Trustee, the Lessor and
the Lessee,  execution by the Lessee of this Facility  Lease shall be conclusive
proof of the  compliance  of Unit 1  (including  any Capital  Improvement),  the
Undivided  Interest and the Real Property Interest with all requirements of this
Facility  Lease,  and the Lessee  acknowledges  and agrees  that (i) NEITHER THE
LESSOR NOR THE OWNER  PARTICIPANT IS A  MANUFACTURER  OR A DEALER IN PROPERTY OF
SUCH KIND AND (ii) THE LESSOR LEASES AND THE LESSEE TAKES THE UNDIVIDED INTEREST
AND THE REAL PROPERTY INTEREST, AND SHALL TAKE EACH CAPITAL IMPROVEMENT, AND ANY
PART  THEREOF,  AS IS AND  WHERE  IS,  and  neither  the  Lessor  nor the  Owner

ANY LATENT OR OTHER DEFECTS,  WHETHER OR NOT DISCOVERABLE,  NOR SHALL THE LESSOR
OR THE OWNER  PARTICIPANT  BE LIABLE FOR  INCIDENTAL  OR  CONSEQUENTIAL  DAMAGES
(INCLUDING  LIABILITY IN TORT,  STRICT OR  OTHERWISE),  it being agreed that all
such risks, as among the Owner Participant, the Loan Participant, the Collateral
Trust Trustee, the Indenture Trustee, the Lessor and the Lessee, are to be borne
by the Lessee.  The provisions of this Section 6(b) have been  negotiated,  and,

provisions  are  intended  to  be a  complete  exclusion  and  negation  of  any
representations  or warranties by the Lessor,  the Owner  Participant,  the Loan
Participant,  the Collateral Trust Trustee or the Indenture Trustee,  express or
implied,  with  respect  to Unit 1  (including  any  Capital  Improvement),  the

the Lessee (directly or through agents,  including the Operating  Agent), at the
Lessee's expense, to assert for the Lessor's account, during the Lease Term, all
of the  Lessor's  rights (if any) under any  applicable  warranty  and any other
claims (under this Facility  Lease or any Purchase  Document) that the Lessee or
the Lessor may have  against any vendor or  manufacturer  with respect to Unit 1
(including any Capital  Improvement) or the Undivided  Interest,  and the Lessor
agrees to cooperate,  at the Lessee's expense, with the Lessee and the Operating
Agent in asserting such rights.  Any amount  receivable  (without  regard to any
right of setoff or other similar right of any Person  against the Lessee) by the
Lessee as payment  under any such  warranty or other claim against any vendor or
manufacturer  (or, if such warranty or claim  relates to the Undivided  Interest
and the  Retained  Assets,  the portion of such  received  amount  appropriately
allocable  to the  Undivided  Interest)  shall be  applied  in  accordance  with
Sections 9(g), (h) and (i).

                  The Lessee will not  directly  or  indirectly  create,  incur,

the Real Property  Interest,  the Lessor's  title thereto or any interest of the
Lessor or Lessee therein (and the Lessee will promptly, at its own expense, take

commercial  operation,  the functions and substantially at the ratings for which
it was designed,  (B) operate,  service,  maintain and repair Unit 1 and replace

relating to all Operating Funds (as defined in the ANPP Participation Agreement)
provided by it to the Operating Agent under the ANPP Participation Agreement and
(ii)  upon  receipt  of the  requisite  information  from the  Operating  Agent,
relating  to the  application  of such  Operating  Funds  to the  operation  and
maintenance of Unit 1 and the  acquisition,  construction  and  installation  of
Capital Improvements, all in accordance with the Uniform System of Accounts. The
Lessor shall not be obliged in any way to maintain,  alter,  repair,  rebuild or

Property Interest,  or any part thereof, or, except as provided in Section 8(f),
to pay the cost of alteration, rebuilding, replacement, repair or maintenance of
Unit 1, any Capital  Improvement,  the  Undivided  Interest or the Real Property
Interest,  or any part  thereof,  and the Lessee  expressly  waives the right to
perform any such action at the expense of the Lessor  pursuant to any law at any
time in effect.

                  (b)  Inspection.  The  Lessor,  the  Owner  Participant,   the
Indenture  Trustee  and the  Collateral  Trust  Trustee  shall have the right to
inspect PANGS  (subject,  in each event,  to the ANPP  Participation  Agreement,
Applicable  Law,   applicable   confidentiality   undertakings   and  procedures

therefrom (subject as aforesaid) and may, at their expense, discuss the Lessee's
affairs,  finances and accounts with its executive  officers and its independent
public   accountants  (and  by  this  provision,   the  Lessee  authorizes  such
accountants,  in the presence of the Lessee,  to discuss with the Lessor and the
Owner Participant and their respective  authorized  representatives the affairs,
finances and  accounts of the Lessee),  all at such times and as often as may be

or other similar right of any Person against  the  Lessee) by or credited to the
account of the Lessee in accordance  with the ANPP  Participation  Agreement and
any  insurance  proceeds  receivable  (without  regard to any right of setoff or
other  similar  right of any Person  against  the Lessee) for the account of the
Lessor or the  Lessee in  respect  of the loss or  destruction  of, or damage or
casualty to, any such property shall be applied as provided in Section 9(g), (h)
or (i),  as the case  may be.  An  undivided  interest  equal  to the  Undivided
Interest Percentage in property at any time removed from Unit 1 shall remain the
property of the Lessor,  no matter where  located,  until such time as a Capital
Investment constituting a replacement of such property shall have been installed
in Unit 1 or such removed  property has been disposed of by the Operating  Agent
in accordance with the ANPP Participation  Agreement.  Simultaneously  with such
disposition by the Operating Agent,  title to the Lessor's undivided interest in
the removed property shall vest in the Person designated by the Operating Agent,
free  and  clear  of  any  and  all  claims  or  rights  of the  Lessor.  Unless
subparagraph (3) of Section 8(e) shall be applicable,  upon the incorporation of
a Capital  Improvement in Unit 1, without further act, (i) title to an undivided
interest equal to the Undivided Interest  Percentage in such Capital Improvement
shall  vest in the  Lessor  and (ii) such  undivided  interest  in such  Capital
Improvement shall become subject to this Facility Lease and be deemed to be part
of the  Undivided  Interest for all purposes  hereof to the same extent that the
Lessor had an undivided  interest in the  property  originally  incorporated  or
installed in Unit 1. The Lessee  warrants and agrees that the Lessor's  interest
in all  Capital  Improvements  shall be free  and  clear  of all  Liens,  except
Permitted  Liens other than the type specified in clauses (ii),  (iii) and (xii)
of the definition thereof.

                  (d)  Reports.  To the extent  permissible,  the  Lessee  shall
prepare and file in timely  fashion,  or,  where the Lessor shall be required to
file,  the Lessee  shall  prepare and deliver to the Lessor  within a reasonable
time  prior to the date for  filing,  any  reports  with  respect to Unit 1, the
Undivided  Interest or the Real Property  Interest or the condition or operation
thereof that shall be required to be filed with any  governmental  or regulatory
authority.  On or before March 1 of each year and on the Lease Termination Date,
the Lessee  shall  furnish  the Lessor and the Owner  Participant  with a report
stating the total cost of all Capital Improvements and describing separately and
in  reasonable  detail each  Capital  Improvement  (or related  group of Capital

in the case of the first such  report or during  the period  from the end of the
period  covered by the last  previous  report to the  December  31 prior to such
report in the case of  subsequent  reports.  On or  before  March 1 in each year
(commencing  March 1, 1986) and at such  other  times as the Lessor or the Owner
Participant  shall reasonably  request in writing (which request shall provide a
reasonable period for response), the Lessee will report in writing to the Lessor
with respect to (i) the most recent annual capital  expenditure budget submitted
by the Operating Agent to the Lessee in accordance  with the ANPP  Participation
Agreement  and (ii) the then  plans (if any)  which the  Lessee may have for the
financing of the same under Section 8(f).

                  (e)  Title to  Capital  Improvements.  Title  to an  undivided
interest,   equal  to  the  Undivided  Interest  Percentage,   in  each  Capital
Improvement to Unit 1 shall vest as follows:

                (1)  in the  case  of  each  Nonseverable  Capital  Improvement,
whether or not the Lessor shall have financed or provided financing (in whole or
in  part)  for  such  undivided  interest  in  such  Capital  Improvement  by an
Additional Equity Investment or a Supplemental  Financing, or both, effective on
the date such Capital  Improvement  shall have been incorporated or installed in
Unit 1, the Lessor shall,  without further act,  acquire title to such undivided
interest in such Capital Improvement;

                (2) in the case of each Severable  Capital  Improvement,  if the
Lessor shall have financed (by an Additional Equity Investment or a Supplemental
Financing,  or  both)  the  Undivided  Interest  Percentage  of the cost of such
Capital  Improvement,  the Lessor shall,  without further act,  acquire title to
such undivided interest in such Capital Improvement; and

                (3) in the case of each Severable  Capital  Improvement,  if the
Lessor shall not have financed (by either an Additional  Equity  Investment or a
Supplemental  Financing,  or both) the Undivided Interest Percentage of the cost
of such Capital  Improvement,  the Lessee  shall retain title to such  undivided
interest.

                  Immediately  upon  title  to such  undivided  interest  in any
Capital  Improvement  vesting in the Lessor  pursuant  to  sub-paragraph  (1) or
sub-paragraph (2) of this Section 8(e), such undivided  interest in such Capital
Improvement  shall,  without  further act, become subject to this Facility Lease
and be deemed part of the  Undivided  Interest  and Unit 1 and for all  purposes
hereof.

                  (f)  Funding  of the  Cost  of  Capital  Improvements.  Before
placing in service any Capital  Improvement  to Unit 1 the cost of which exceeds
$100,000,000  in respect of the interests of all ANPP  Participants,  the Lessee
shall  give the  Lessor  and the Owner  Participant  reasonable  advance  notice
thereof. The Owner Participant shall have the option, in its sole discretion, of
financing  through the Lessor the cost of any such Capital  Improvement,  or any
other Capital  Improvement  presented to the Owner  Participation for financing,
including or not including the making of an investment by the Owner  Participant
(an Additional  Equity  Investment)  and the issuance of one or more  Additional
Notes, all on terms acceptable to the Lessee and the Owner  Participant.  If the
Owner  Participant  does not finance,  or arrange the  financing of, the cost of
such Capital  Improvement,  the Lessee may cause the Lessor to issue,  if and to
the extent  permitted by the  Indenture,  to one or more Persons (other than any
Person affiliated with the Lessee within the meaning of Section 318 of the Code)
one or more Additional  Notes and to use the proceeds thereof to pay the cost of
such Capital Improvement, subject to satisfaction of the following conditions:

                  (i) there shall be no more than one Supplemental  Financing in
any calendar year;

                  (ii)  the sum of the  Supplemental  Financing  Amounts  in any
calendar  year  shall  equal or exceed  the  Undivided  Interest  Percentage  of
$5,000,000;

                (iii) the Lessee may include in any  request for a  Supplemental
Financing only Capital  Improvements not previously financed in any Supplemental
Financing  and which  have been  installed  or  affixed  no  earlier  than three
calendar  years  before  the  beginning  of the  calendar  year  in  which  such
Supplemental Financing occurs;

                  (iv) the total amount of all Supplemental Financing during the
Basic  Lease  Term  shall  not  exceed  the  Undivided  Interest  Percentage  of
$100,000,000;

                (v) unless waived by the Owner Participant, the Bonds issued and
outstanding  under the Collateral  Trust  Indenture  shall be rated no less than
"investment  grade", as determined by Standard & Poor's  Corporation and Moody's
Investors Service, Inc.;

                (vi) the  Supplemental  Financing  Amount  shall not exceed that
portion  of  the  cost  of  Capital  Improvements  which,  when  financed,  will
constitute  an addition to the Owner  Participant's  basis under section 1012 of
the Code;

                (vii) in the  opinion of  independent  tax  counsel to the Owner
Participant,  such  Supplemental  Financing  shall  not  result in  adverse  tax
consequences  to the Owner  Participant  or adversely  affect the status of this
Facility  Lease as a "true  lease"  for  Federal  tax  purposes,  and the  Owner
Participant  and the  Lessor  shall  have  agreed  upon the amount and manner of
payment of any indemnity (if any) payable by the Lessee as a consequence of such
Supplemental Financing;

                  (viii) the  Additional  Notes shall have a final maturity date
no later than January 15, 2015;

                (if) the Lessee shall have made such representations, warranties
and covenants  regarding the tax  characteristics  of each undivided interest in
each  Capital  Improvement  as  the  Owner  Participant  requests  and  the  Tax
Indemnification Agreement shall have been appropriately modified;

                (x)  appropriate  adjustments to Basic Rent and the schedules of
Casualty Values,  Special Casualty Values and Termination Values shall have been
agreed to by the Owner Participant;

                  (xi) The Lessee shall pay to the Lessor an amount equal to all
out-of-pocket  costs and expenses reasonably incurred by the Lessor or the Owner
Participant not financed as a part of such  Supplemental  Financing or reflected
in adjustments to Basic Rent;

                  (xii) no Default or Event of Default  shall have  occurred and

                (xiii) the Lessee  shall  enter into such  agreements  and shall
provide such tax indemnities, representations,  warranties, covenants, opinions,
certificates  and other  documents  as the Owner  Participant  shall  reasonably
request.

                  (g) Useful  Life.  If the Lessee  shall not  theretofore  have
exercised its option under Section 13 to purchase the Undivided Interest and the
Real  Property  Interest,  then (i) if the  Lessee  shall not  theretofore  have
exercised  its option to renew the Lease  pursuant to Section 12, on January 15,
2014,  the Lessee shall  initiate  the  Appraisal  Procedure  to  determine  the
remaining  economic  useful  life of Unit 1 as of July 15,  2014 and (ii) on the

any,  the Lessee  shall  initiate  the  Appraisal  Procedure  to  determine  the
remaining  economic useful life of Unit 1 as of the date six months prior to the
end of the  Renewal  Term.  The Lessee  and the  Lessor  agree to use their best
efforts to ensure that such  determination of remaining  economic useful life is
made no later than July 15,  2014 (in the case of the first such  determination)
and six months  prior to the end of the Renewal  Term (in the case of the second
such determination).

                  SECTION 9. Event of Loss; Deemed Loss Event.

                  (a) Damage or Loss. In the event that Section 16.2 of the ANPP
Participation  Agreement  (as  in  effect  on  the  date  hereof)  shall  become
applicable,  or an Event of Loss, a Requisition of Use or a Requisition of Title

damage,  loss,  condemnation,  confiscation,  theft or  seizure  for any  reason
whatsoever,  such fact shall promptly, and in any case within five Business Days

Participant.

                  (b)  Repair.  The  Lessee  shall  promptly  make  any  and all

in no event be obligated to make or join in any agreement  under Section 16.2 of
the ANPP  Participation  Agreement (as in effect on the date hereof)  concerning
repairs to or reconstruction of Unit 1.

                  (c) Payment of Casualty  Value. On the Basic Rent Payment Date
next  following the  occurrence of an Event of Loss, the Lessee shall pay to the

to the excess of (i)  Casualty  Value  determined  as of such Basic Rent Payment
Date, plus an amount equal to the execww of (i) Casualty Value  determined as of
such Basic Rent Payment Date over (ii) the unpaid  principal amount of the Notes
Outstanding  on such date after  giving  effect to the  payment,  if any, of the
principal  installment  due and payable on such date. Upon compliance in full by
the Lessee with the foregoing  provisions of this Section 9(c) and assumption by
the Lessee of all the obligations and liabilities of the Owner Trustee under the
Indenture and the Notes pursuant to Section 3.9(b) of the Indenture,  the Lessor
shall (so long as no  Default or Event of Default  shall  have  occurred  and be
continuing),  and at any time  after  the  occurrence  of an Event of Loss,  the
Lessor may:

                (1) in the  case  of an  Event  of  Loss  arising  from a  Final
Shutdown,  if the Lessee shall have declined,  but one or more of the other ANPP
Participants shall have elected,  to reconstruct or restore Unit 1, as permitted
by the ANPP  Participation  Agreement,  Transfer the Undivided  Interest and the
Real Property Interest to such electing ANPP Participants, as required by and in
the proportions set forth in the ANPP Participation Agreement, in which case the
Lessee shall be entitled to receive the portion of the "salvage  value" purchase
price allocable to the Undivided Interest; or

                  (2) if  clause  (1)  shall  not be  applicable,  Transfer  the
Undivided Interest and the Real Property Interest to the Lessee.

If the Lessee shall not have assumed all the  obligations and liabilities of the
Owner  Trustee  under the  Indenture  and the Notes in  accordance  with Section
3.9(b) of the  Indenture,  but  shall  have paid all  amounts  required  by this
Section  9(c),  the Lessor  shall  retain the  Undivided  Interest  and the Real
Property  Interest  subject to the terms of this Facility Lease and Section 7(b)
(4) of the Participation Agreement;  provided,  however, that (i) the obligation

                                     - 20 -

of the  Lessee to pay  further  Basic Rent shall be reduced to an amount on each
Basic Rent Payment Date equal to the aggregate amount of the principal, premium,
if any, and accrued interest then payable on all Notes then Outstanding and (ii)
this  Facility  Lease  shall  become a security  agreement  for all  purposes of
Applicable Law.

                  (d) Payment of Special  Casualty Value. If a Deemed Loss Event
occurs,  the party hereto having knowledge  thereof and, at the Lessor's option,
on the day of the month  (specified  in  Schedule  4) next  following  the month
during which the Deemed Loss Event occurs, the Lessee shall pay to the Lessor on
such day an amount equal to the excess of (i) Special  Casualty Value determined
as of the date such payment is due over (ii) the  principal  amount of the Notes
Outstanding  on such date after  giving  effect to the  payment,  if any, of the
principal instalment due and payable on such day. Upon compliance in full by the
Lessee with the foregoing  provisions of this Section 9(d) and assumption by the
Lessee of all the  obligations  and  liabilities  of the Owner Trustee under the
Indenture and the Notes pursuant to Section 3.9(b) of the Indenture,  the Lessor
shall (so long as no  Default or Event of Default  shall  have  occurred  and be
continuing),  and at any time after the  occurrence of a Deemed Loss Event,  the
Lessor may,  Transfer the Undivided  Interest and the Real Property  Interest to
the  Lessee.  If the  Lessee  shall not have  assumed  all the  liabilities  and
obligations of the Owner Trustee under the Indenture and the Notes in accordance
with Section 3.9(b) of the Indenture but shall have paid all amounts required by
this Section 9(d),  the Lessor shall retain the Undivided  Interest and the Real
Property  Interest  subject to the terms of this Facility Lease and Section 7(b)
(4) of the Participation Agreement;  provided,  however, that (i) the obligation
of the  Lessee to pay  further  Basic Rent shall be reduced to an amount on each
Basic Rent Payment Date equal to the aggregate amount of principal,  premium, if
any, and accrued  interest then payable on all Notes  Outstanding  and (ii) this
Facility Lease shall become a security  agreement for all purposes of Applicable
Law.

                  (e)  Requisition  of Use. In the case of a Requisition  of Use
not constituting an Event of Loss, this Facility Lease shall continue,  and each
and every obligation of the Lessee hereunder and under each Transaction Document
shall remain in full force and effect. So long as no Default or Event of Default
shall have occurred and be continuing,  the Lessee shall be entitled to all sums
received by reason of any such  Requisition  of Use for the period ending on the

Lease Termination Date, and the Lessor shall be entitled to all sums received by
reason of any such Requisition of Use for the period after the Lease Termination
Date.

                  (f)  Termination  of  Obligation.  Until the Lessee shall have
made the payments  specified in Section 9(c) or 9(d),  the Lessee shall make all
payments of Rent when due; and the Lessee shall  thereafter  be required to make
all payments of Supplemental  Rent as and when due. In the event that the Lessee
shall assume all the  obligations and liabilities of the Owner Trustee under the
Indenture  and the Notes  pursuant  to  Section  3.9(b) of the  Indenture,  upon
payment by the Lessee of the payments  specified in Section 9(c) or 9(d) and all
Rent due and owing through and including  the date of payment  (including  Basic
Rent due on or accrued  through  such date,  as the case may be), the Lease Term
shall end and the Lessee's obligation to pay further Basic Rent shall cease.

                  (g)  Application of Payments on an Event of Loss. Any payments
receivable  (without regard to any right of setoff or other similar right of any
Person  against the Lessee) at any time by the Lessor or the Lessee  (other than
insurance  placed by the Owner  Trustee  or the Owner  Participant  pursuant  to
Section 10(b)) from any governmental authority,  insurer or other Person (except
the Lessee) as a result of the  occurrence  of an Event of Loss shall be applied
as follows:

                  (i) all such payments received at any time by the Lessee shall
be  promptly  paid to the  Lessor  for  application  pursuant  to the  following
provisions of this Section  9(g),  except that the Lessee may retain any amounts
that  would at the time be  payable  to the  Lessee as  reimbursement  under the
provisions of clause (ii) below;

                  (ii) so much of such  payments  as shall not exceed the amount
required to be paid by the Lessee pursuant to Section 9(c)  (ignoring,  for this
purpose,  clause  (ii) of the  first  sentence  thereof)  shall  be  applied  in
reduction of the Lessee's  obligation  to pay such amount if not already paid by
the Lessee or, if already paid by the Lessee,  shall be applied to reimburse the
Lessee for its payment of such amount; and

                  (iii)  the  balance,   if  any,  of  such  payments  remaining
thereafter shall be divided between the Lessor and the Lessee as their interests
may appear.

                  (h)  Application of Payments Not Relating to an Event of Loss.
Payments  receivable  (without  regard to any  right of setoff or other  similar
right of any Person  against the  Lessee) at any time by the Lessor  (other than
insurance  placed by the Owner  Trustee  or the Owner  Participant  pursuant  to
Section 10(b)) or the Lessee from any Governmental  Authority,  insurer or other
Person  with   respect  to  any   destruction,   damage,   loss,   condemnation,
confiscation,  theft or seizure of or  Requisition of Title to or Requisition of
Use of Unit 1 or any part  thereof  not  constituting  an Event of Loss shall be
applied first to reimburse the Lessee for all amounts expended in respect of the
repair,  replacement or reconstruction of Unit 1 or any part thereof as provided
in Section  9(b),  and second the  balance,  if any, of such  payments  shall be
divided between the Lessor and the Lessee as their interests may appear.

                  (i)  Other   Dispositions.   Notwithstanding   the   foregoing
provisions  of this  Section 9, so long as a Default  or Event of Default  shall
have occurred and be continuing,  any amount that would  otherwise be payable to
or for the  account  of, or that  would  otherwise  be  retained  by, the Lessee
pursuant to Section 10 or this Section 9 shall be paid to the Lessor as security
for the  obligations  of the Lessee under this Facility  Lease and, at such time
thereafter  as no Default or Event of Default shall be  continuing,  such amount
shall be paid  promptly  to the Lessee  unless  this  Facility  Lease shall have
theretofore been declared to be in default,  in which event such amount shall be
disposed of in accordance  with the provisions  hereof,  of the Indenture and of
the Trust Agreement.

                  (j)  Assumption  of  Notes;  Creation  of  Lien  on  Undivided
Interest.  In  connection  with an  Event of Loss,  a Deemed  Loss  Event or the
exercise of the Cure  Option,  (i) the Lessee  agrees to use its best efforts to
comply with the conditions  respecting its assumption of all the obligations and
liabilities  of the Owner Trustee under the Indenture and the Notes set forth in
Section 3.9(b) of the Indenture,  and (ii) the Lessor agrees that, if the Lessee
fails to assume all the  obligations  and liabilities of the Owner Trustee under
the Indenture and the Notes in accordance  with Section 3.9(b) of the Indenture,
not later  than two  Business  Days  prior to the date on which the Lessee is to
acquire the Owner Participant's interest in the Trust Estate pursuant to Section


6091.20.2898.47:1

7(b) (4) of the  Participation  Agreement,  the Lessor will cause the  Undivided
Interest  and the Real  Property  Interest  to be  subjected  to the Lien of the
Indenture by executing and  delivering  to the  Indenture  Trustee the Undivided
Interest Indenture Supplement.

                  SECTION 10.  Insurance.

                  (a) Required  Insurance.  The Lessee will use its best efforts
to cause the Operating Agent to carry and maintain  insurance required under the
ANPP  Participation  Agreement and will make all payments required of the Lessee
under the ANPP Participation Agreement in respect of such insurance.  The Lessee
will at all times maintain, directly or through the Operating Agent, policies of
casualty and liability  insurance with respect to the Undivided Interest and the
Real  Property  Interest  in such  amounts  and with such  coverage  as shall be
adequate in accordance with prudent utility practice.  Any policies of insurance
in  respect  of  destruction,  damage,  loss,  theft  or other  casualty  to the
Undivided Interest, the Real Property Interest, Unit 1 or any part thereof shall
name the Lessor  (and,  to the extent  practicable,  the Owner  Participant)  as
additional  insured,  as its interests may appear, and any policies with respect
to nuclear  liability  insurance  shall  include all  Indemnities  as additional
insureds;  provided,  however,  that if the Operating  Agent, as trustee,  shall
become  the loss  payee  under any  policy  of  insurance  constituting  Project
Insurance,  then  the  Lessor  and the  Owner  Participant  shall be and be made
beneficiaries of the trust  arrangement  under which the Operating Agent acts as
trustee.  The Lessee shall, on or before March 1 of each year,  commencing March
1,  1986,  furnish to the Lessor  and the Owner  Participant  (A) a  certificate
signed by an independent  insurance broker showing the insurance then maintained
under the ANPP Participation Agreement and hereunder,  stating that all premiums
then due have  been  paid  and  stating  that the  insurance  then  carried  and
maintained under the ANPP Participation Agreement and hereunder is in accordance
with the terms of the ANPP Participation  Agreement and this Section 10, and (B)
upon the request of the Lessor or the Owner  Participant,  copies (to the extent
permitted  by the  issuers of such  policies)  of policies  so  maintained.  All
insurance proceeds paid in respect of damage, destruction,  loss, theft or other
casualty  to the  Undivided  Interest  or the Real  Property  Interest  shall be
applied as provided in Section 9(g) (h) or (i), as the case may be.

<PAGE>


                  (b)  Permitted  Insurance.  Nothing  in this  Section 10 shall
prohibit the Lessee from placing,  at its expense,  insurance on or with respect
to the cost of purchasing replacement power, naming the Lessee as insured and/or
loss payee,  unless such insurance  would  conflict with or otherwise  limit the
availability  of  insurance  to be provided or  maintained  in  accordance  with
Section 10(a). Nothing in this Section 10 shall prohibit the Lessor or the Owner
Participant  from placing at its expense  other  insurance on or with respect to
Unit 1, the Undivided Interest or the Real Property Interest or the operation of
Unit 1, naming the Lessor or the Owner Participant as insured and/or loss payee,
unless such insurance would conflict with or otherwise limit the insurance to be
provided or maintained in accordance with Section 10(a).

                  SECTION 11. Rights to Assign or Sublease.

                  (a)  Assignment  or Sublease by the Lessee.  Without the prior
written consent of the Lessor, the Lessee shall not assign,  sublease,  transfer
or encumber (except for Permitted Liens) its leasehold interest in the Undivided
Interest or the Real Property  Interest  under this Facility  Lease.  The Lessee
shall  not,  without  the prior  written  consent  of the  Lessor  and the Owner
Participant,  part with the possession of, or suffer or allow to pass out of its
possession,  the Undivided Interest,  the Real Property Interest or any interest
therein,  except  to the  extent  required  pursuant  to the ANPP  Participation
Agreement or expressly permitted by the provisions of this Facility Lease or any
other Transaction Document.

                  (b) Assignment by Lessor as Security for Lessor's Obligations.
To secure the indebtedness evidenced by the Notes, the Lessor will assign to the
Indenture  Trustee its right,  title and interest to receive certain payments of
Rent (not including, in any event, Excepted Payments), to the extent provided in
the  Indenture  and may assign to the  Indenture  Trustee  its right,  title and
interest  in  the  Undivided   Interest  and  the  Real  Property   Interest  as
contemplated  by Section 9(j). The Lessee hereby (a) consents to such assignment
pursuant  to the  terms of the  Indenture,  (b)  agrees to pay  directly  to the
Indenture Trustee at the Indenture  Trustee's Office (so long as the lien of the
Indenture  has not been  satisfied  and  discharged  and the Lessor is obligated
thereunder) all amounts of Rent (other than Excepted  Payments) due or to become
due to the Lessor  that shall be required  to be paid to the  Indenture  Trustee
pursuant to the Indenture, (c) agrees that the

                                     - 25 -

right of the  Indenture  Trustee  to any such  payments  shall be  absolute  and
unconditional  and  shall  not  be  affected  by  an  circumstances  whatsoever,
including,  without  limitation,  those circumstances set forth in Section 4 and
(d) agrees that, to the extent provided in the Indenture and until the Indenture
is discharged in accordance with its terms, the Indenture Trustee shall have all
the rights of the Lessor  hereunder with respect to Assigned  Payments as if the
Indenture Trustee had originally been named herein as the Lessor.

                  SECTION 12.  Lease Renewal.

                  Subject to the notice requirements set forth in Section 13(a),
at the end of the Basic Lease Term provided  that no Default,  Event of Default,
event of Loss or Deemed Loss Event shall have occurred and be continuing and the
Notes shall have been paid in full, the Lessee shall have the right to renew the
term of this Facility Lease for a period commencing January 15, 2015, and ending
on the later of January 15, 2017 and the end of the Maximum  Option  Period (the
Renewal Term),  during which the Basic Rent payable shall be the rental provided
in Section 3(a) (iii) and Section 21.

                  SECTION 13.  Notices for Renewal or Purchase;
Purchase Options.

                  (a) Notice;  Determination of Values; Appraisal Procedure. Not
later than three years nor earlier than five years prior to the expiration  date
of the Basic  Lease Term,  and not later than three years nor earlier  than five
years prior to the expiration  date of the Renewal Term, as the case may be, the
Lessee shall give to the Lessor  written  notice of its  election  either to (A)
return the  Undivided  Interest  and the Real  Property  Interest  to the Lessor
pursuant to Section 5, or (B) exercise the renewal  option  permitted by Section
12 (in the case of the notice delivered in respect of the expiration date of the
Basic Lease Term) or the  purchase  option  permitted by Section  13(b).  If the
notice  specified in clause (B) of the  preceding  sentence is given three years
prior to the  expiration of the Basic Lease Term,  then not later than two years
prior to the  expiration  date of the Basic Lease Term, the Lessee will give the
Lessor  written  notice of its election  either to exercise  the renewal  option
permitted by Section 12 or the purchase option  permitted by Section 13(b).  Any
such election shall be irrevocable as to the Lessee,  but no such election shall
be  binding on the Lessor if, on the  effective  date  thereof,  a Default or an
Event of Default shall have occurred and be continuing or an Event of Loss

                                     - 26 -

<PAGE>



or a Deemed Loss Event shall have occurred. Promptly after giving notice, (i) in
case the renewal  option has been  elected,  the Maximum  Option Period shall be
determined  by the  Appraisal  Procedure,  or (ii) in case the  purchase  option
permitted  by  Section  13(b)  has  been  elected,  the  Lessee  and  the  Owner
Participant shall agree upon the Fair Sales Value of the Undivided  Interest and
the Real  Property  Interest,  or, if within  three months after the date of the
Lessee's  notice  the  Lessee  and the Owner  Participant  shall be unable so to
agree, such value shall be determined by the Appraisal Procedure.

                  (b) Purchase  Option at Expiration of the Lease Term.  Subject
to the notice  requirements  set forth in Section 13(a),  unless a Default or an
Event of Default  shall have  occurred and be  continuing or an Event of Loss or
Deemed  Loss Event shall have  occurred,  on the date of the  expiration  of the
Basic Lease Term or the Renewal  Term (if  elected),  the Lessee  shall have the
right to purchase the Undivided  Interest and the Real  Property  Interest for a
purchase price equal to the Fair Market Sales Value thereof.

                  (c)  Special  Purchase  Option.  Upon 30 days'  prior  written
notice  to the  Lessor,  unless a  Default  or an Event of  Default  shall  have
occurred  or be  continuing  or an Event of Loss or Deemed Loss Event shall have
occurred,  if the Lessee  shall  determine  that upon a refunding of the Initial
Series Note (and the  Releveraging  Note, if theretofore  issued) such refunding
would violate any  limitation  then imposed by the NMPSC,  the Lessee shall have
the right to purchase the Undivided  Interest and the Real Property Interest for
a purchase price equal to the greater of (i) the Fair Market Sales Value thereof
and (ii)  Casualty  Value as of the Basic Rent Payment Date first  preceding the
date of such purchase (or as of the date of such purchase, if such date shall be
a Basic Rent Payment  Date) plus, if such date shall not be a Basic Rent Payment
Date, a pro ration of Basic Rent to the date of purchase.

                  (d) Purchase of the Undivided Interest;  Payment,  Etc. If the
Lessee shall have elected to purchase the Undivided pursuant to Section 13(b) or
Section  (c),  payment by the  Lessee of the  purchase  price for the  Undivided
Interest and the Real Property  Interest shall be made in immediately  available
funds,  whereupon the Lessor shall Transfer the Undivided  Interest and the Real
Property Interest to the Lessee.

                  SECTION 14.  Termination for Obsolescence.

                  (a) Termination  Notice.  Notwithstanding any provision herein
contained to the  contrary,  unless a Default or an Event of Default  shall have
occurred and be continuing or an Event of Loss or a Deemed Loss Event shall have
occurred,  the Lessee shall have the option (provided that the Lessee shall have
delivered to the Lessor an Officers' Certificate to the effect that the Lessee's
Board of Directors  has adopted and there is in effect a resolution  determining
that Unit 1 is (A) uneconomic to the Lessee or (B) economically obsolete for any
reason;  and provided that the Lessee shall be disposing of all its other leased
interests in Unit 1, on at least 360 days' prior written  notice (a  Termination
Notice) to the Lessor,  the Owner  Participant and the Indenture  Trustee (which
notice shall be irrevocable)) to terminate this Facility Lease on any Basic Rent
Payment  Date  after  January  15,  1998,  and prior to  January  15,  2012 (the
Termination Date). If the Lessee shall give the Lessor a Termination Notice, the
Lessee shall, as agent for the Lessor,  use its best efforts to obtain cash bids
for the  purchase of the  Undivided  Interest  and the Real  Property  Interest,
together with the interest of the Lessor under the  Assignment  and  Assumption.
The Lessor shall also have the right to obtain such cash bids,  either  directly
or through agents other than the Lessee.  The Lessee shall certify to the Lessor
within ten days after the Lessee's receipt of each bid (and, in any event, prior
to the  Termination  Date) the amount and terms thereof and the name and address
of the party  (which  shall not be the Lessee or any  Affiliate  of the  Lessee)
submitting such bid.

                  (b)  Right  of  Lessor  to  Retain  Undivided   Interest  upon
Termination.  The Lessor may elect to retain,  rather than sell,  the  Undivided
Interest and the Real  Property  Interest by giving  notice to the Lessee and to
the  Indenture  Trustee prior to the  Termination  Date. It shall be a condition
precedent to the Lessor's  right to retain the  Undivided  Interest and the Real
Property Interest that on or prior to the Termination Date the Lessor shall have
paid (or made  provision  for  payment)  to the  Indenture  Trustee,  the unpaid
principal amount of all Notes Outstanding on such date and all premium,  if any,
and interest accrued and unpaid on the date of payment.  If the Lessor elects to
retain the Undivided  Interest and the Real Property  Interest  pursuant to this
Section 14(b),  the Lessee shall pay to the Lessor on the  Termination  Date the
Basic  Rent and any  other  Rent  due or  accrued,  as the  case may be,  to and
including the Termination Date, together with an amount equal to the

excess,  if any, of the Termination  Value as of the  Termination  Date over the
highest bona fide offer received pursuant to Section 14(a).

                  (c)  Events on the  Termination  Date.  If the  Lessor has not
elected to retain the  Undivided  Interest  and the Real  Property  Interest  as
provided  in Section  14(b),  on the  Termination  Date the Lessor  shall  (upon
receipt  of the sale price and all  additional  payments  specified  in the next
sentence)  Transfer the Undivided  Interest and the Real  Property  Interest for
cash to the bidder (which shall not be the Lessee or an Affiliate of the Lessee)
that shall have submitted the highest bid on or before the Termination Date. The
total sale price realized at such sale shall be retained by the Lessor (subject,
however, to the terms of the Indenture and the requirement that there shall have
been paid, or provision  for payment  made, to the Indenture  Trustee the unpaid
principal of all Notes  Outstanding on the Termination Date and all premium,  if
any, and interest  accrued and unpaid on the date of payment)  and, in addition,
on the  Termination  Date the Lessee shall pay to the Lessor (A) the excess,  if
any, of the Termination Value as of the Termination Date over the net sale price
of the Undivided  Interest and the Real Property Interest and (B) any Basic Rent
due or accrued,  as the case may be, to and including the  Termination  Date and
shall pay to the Person or Persons entitled thereto all Supplemental Rent (other
than  Termination  Value).  Upon  compliance  by the Lessee with the  applicable
provisions  of this Section 14, the  obligation  of the Lessee to pay Basic Rent
due  hereunder  for any period  after the  Termination  Date shall cease and the
Basic Lease Term shall end on the Termination Date; provided,  however, that, in
the event of termination of this Facility Lease pursuant to this Section 14, the
obligations  of the Lessee  under the ANPP  Participation  Agreement  (except as
therein expressly  provided) and the Assignment and Assumption shall continue in
full  force  and  effect  and  shall  not be  impaired  by  reason  of any  such
termination.  If, other than as a result of the Lessor's  election to retain the
Undivided  Interest and the Real Property Interest as provided in Section 14(b),
on or as of the  Termination  Date no such sale shall occur or the Lessee  shall
not have  complied  in full with this  Section  14,  this  Facility  Lease shall
continue in full force and effect in accordance with its terms without prejudice
to the Lessee's  right to exercise its rights under this Section 14  thereafter,
except  that the Lessee  shall not be entitled  to deliver  another  Termination
Notice during the 3-year period  following  such  Termination  Date.  The Lessor
shall be under no duty to  solicit  bids,  to  inquire  into the  efforts of the

sale other than, if the Lessor has not elected to retain the Undivided  Interest
and the Real Property Interest,  to Transfer the Undivided Interest and the Real
Property  Interest to the  purchaser  named in the highest bid  certified by the
Lessee to the Lessor or obtained by the Lessor,  against receipt of the payments
provided for herein.

                  (d) Early  Termination  Notice.  In the event  that the Lessee
shall fail to exercise  its renewal  option or purchase  option  within the time
limit provided by Section 13(a), the Lessor shall have the option,  on any Basic
Rent  Payment Date  thereafter,  on at least 120 days prior  written  notice (an
Early Termination  Notice) to the Lessee and the Indenture Trustee, to terminate
this Facility Lease on the Basic Rent Payment Date specified in such notice (the
Early  Termination  Date).  Any Early  Termination  Notice may be revoked by the
Lessor at any time on or prior to the Early Termination Date.

                  (e)  Events  on the  Early  Termination  Date.  On  the  Early
Termination  Date the Lessor  shall,  at its option,  (i) Transfer the Undivided
Interest and the Real Property  Interest to the bidder (other than the Lessee or
any Affiliate of the Lessee) selected by the Lessor or (ii) retain the Undivided
Interest and the Real Property  Interest.  It shall be a condition  precedent to
the  Lessor's  right  to sell or  retain  the  Undivided  Interest  and the Real
Property  Interest  that on or prior to the Early  Termination  Date the  Lessor
shall have paid (or made provision for payment) to the Indenture Trustee on such
date the unpaid principal  amount of all Notes  Outstanding on such date and all
premium,  if any,  and interest  accrued and unpaid on the date of payment.  The
total sale price  realized at any such sale shall be retained by the Lessor and,
in addition,  on the Early  Termination  Date the Lessee shall pay to the Lessor
any Basic Rent due or accrued,  as the case may be, to and  including  the Early
Termination  Date, and shall pay to the Person or Persons  entitled  thereto all
Supplemental  Rent (other than  Termination  Value).  Upon compliance the Lessee
with the applicable  provisions of this Section 14, the obligation of the Lessee
to pay Basic Rent due hereunder for any period after the Early  Termination Date

provided,  however,  that in the event of the termination of this Facility Lease
pursuant  to this  Section  14, the  obligations  of the  Lessee  under the ANPP
Participation   Agreement  (except  as  therein  expressly   provided)  and  the
Assignment and Assumption  shall continue in full force and effect and shall not
be impaired by reason of any such termination.

the  giving  by any ANPP  Participant  of a notice  under  Section  23.2 (or any
comparable successor provision) of the ANPP Participation Agreement respecting a
default  thereunder  by the  Lessee and the lapse of 20  Business  Days from the
giving of such notice  without the Lessee having cured such  default;  provided,
however,  that for purposes of this clause (2) if the Lessee shall have disputed
the  existence  or nature of a default  and such  dispute  shall have become the
subject  of an  arbitration  under  Section  24  (or  any  comparable  successor

such  failure;  or (2) any other  default  under  any  agreement  or  instrument
relating to any such Debt,  or any other event,  shall occur and shall  continue
after the  applicable  grace  period,  if any,  specified  in such  agreement or
instrument,  if the  effect of such  default  or event is to  accelerate,  or to
permit the  acceleration  of, the maturity of such Debt,  but only if the Lessee
shall  have  received  notice of such  default or a  Responsible  Officer of the
Lessee shall have actual knowledge of such default.

                  SECTION 16. Remedies.

                  (a) Remedies.  Upon the occurrence of any Event of Default and
so long as the same shall be continuing,  the Lessor may, at its option, declare

if they Undivided Interest and the Real Property Interest were being returned at

liability to the Lessee for or by reason of such entry or taking of  possession,
whether  for the  restoration  of damage to  property  caused by such  taking or
otherwise;

                (iii) the Lessor may sell the  Undivided  Interest  and the Real
Property Interest, or any part thereof, together with any interest of the Lessor
under the  Assignment and  Assumption,  at public or private sale, as the Lessor
may  determine,  free and  clear of any  rights of the  Lessee in the  Undivided
Interest and the Real  Property  Interest and without any duty to account to the
Lessee with  respect to such action or inaction  or any  proceeds  with  respect
thereto (except to the extent required by clause (v) or (vi) below if the Lessor
shall  elect to exercise  its rights  thereunder),  in which event the  Lessee's
obligation to pay Basic Rent hereunder for periods  commencing after the date of
such sale shall be terminated  or  proportionately  reduced,  as the case may be
(except to the extent that Basic Rent is to be included  in  computations  under
clause  (v) or (vi)  below if the  Lessor  shall  elect to  exercise  its rights
thereunder);

                (iv) the  Lessor  may hold,  keep idle or lease to others all or
any part of the Undivided Interest and the Real Property Interest, as the Lessor
in its sole discretion may determine, free and clear of any rights of the Lessee
and  without  any duty to account to the Lessee  with  respect to such action or
inaction or for any proceeds  with  respect to such action or  inaction,  except
that the Lessee's  obligation to pay Basic Rent for periods commencing after the
Lessee shall have been  deprived of use of the  Undivided  Interest and the Real
Property  Interest  pursuant  to this  clause  (iv)  shall be reduced by the net
proceeds, if any, received by the Lessor from leasing the Undivided Interest and

the Real  Property  Interest  to any  Person  other than the Lessee for the same
periods or any portion thereof;

                (v)  except  in the  case of an Event of  Default  specified  in
clause (iii) of Section 15, the Lessor may, whether or not the Lessor shall have
exercised or shall  thereafter at any time exercise its rights under clause (i),
(ii), (iii) or (iv) above,  demand, by written notice to the Lessee specifying a
payment  date which shall be a Basic Rent  Payment Date not earlier than 10 days
after the date of such notice, that the Lessee pay to the Lessor, and the Lessee
shall pay to the  Lessor,  on the Basic  Rent  Payment  Date  specified  in such
notice,  as  liquidated  damages  (in lieu of the Basic Rent due after the Basic
Rent Payment  specified in such  notice),  any unpaid Rent due through the Basic
Rent Payment  Date  specified  in such notice plus  whichever  of the  following
amounts  the  Lessor,  in its sole  discretion,  shall  specify  in such  notice

1) as of the Basic Rent Payment Date specified in such notice; or

                (C) an amount  equal to the  excess,  if any, of (1) the present

over (2) the present value as of such Basic Rent Payment Date of the Fair Market
Rental  Value  of  the  Undivided   Interest  and  the  Real  Property  Interest
(determined  on the basis of the then actual  condition of Unit 1) until the end
of the Basic  Lease Term or the  Renewal  Term,  as the case may be,  discounted
semi-annually at a rate of 10% per annum;

                (vi) if the Lessor  shall have sold all the  Undivided  Interest

through such Basic Rent Payment Date, plus the amount of any deficiency  between
the Sale  Proceeds  and Casualty  Value,  computed as of such Basic Rent Payment
Date, together with interest at the interest rate specified in Section 3(b)(iii)
on the amount of such Rent and such  deficiency from the date of such sale until
the date of actual payment;

                (vii) in the case of an Event of  Default  specified  in  clause
(iii) of Section  15, the Lessor  may  demand,  by written  notice of the Lessee
specifying a payment date which shall be the last Basic Rent Payment Date of the
Lease Term,  that the Lessee pay to the Lessor,  and the Lessee shall pay to the
Lessor,  on such Basic Rent Payment Date,  as  liquidated  damages for loss of a
bargain  and not as a  penalty,  any  unpaid  Rent due  through  such Basic Rent
Payment Date plus an amount equal to the Fair Market Sales Value (without regard
to the obligations of the Lessee under Section 10(b)(3)(xi) of the Participation
Agreement) of the Undivided Interest and the Real Property Interest  (determined
on the basis of the then  actual  condition  of Unit 1)  deter-mined  as of such
Basic Rent Payment Date  (together  with interest on such amount at the interest
rate specified in Section  3(b)(iii) from such Basic Rent Payment Date specified
in such notice to the date of actual  payment) (and upon receipt of such payment
the Lessor  shall  transfer to the Lessee the  Undivided  Interest  and the Real
Property Interest); or

                (viii) the Lessor may  exercise  any other  right or remedy that
may be available to it under any Applicable Law or proceed by appropriate  court
action to enforce the terms hereof or to recover damages for the breach hereof.

                  (b) No Release. No restriction or termination of this Facility
Lease,  in whole or in part, or  repossession  of the Undivided  Interest or the
Real  Property  Interest or exercise of any remedy under  paragraph  (a) of this
Section 16 shall, except as specifically provided therein, relieve the Lessee of
any of its liabilities and obligations hereunder.  In addition, the Lessee shall
be liable,  except as otherwise  provided above, for any and all unpaid Rent due
hereunder before, after or during the exercise of any of the foregoing remedies,
including all reasonable legal fees and other costs and expenses incurred by the
Lessor or the Owner  Participant  by  reason of the  occurrence  of any Event of
Default or the exercise of the Lessor's  remedies with respect  thereto.  At any
sale of the Undivided  Interest,  the Real Property Interest or any part thereof
pursuant to this Section 16, the Owner Participant,  the Lessor or the Indenture
Trustee may bid for and purchase such property.

                  (c) Remedies Cumulative. No remedy under paragraph (a) of this
Section 16 is  intended to be  exclusive,  but each shall be  cumulative  and in
addition to any other  remedy  provided  under such  paragraph  (a) or otherwise
available to the Lessor at law or in equity. No express or implied waiver by the
Lessor of any Default or Event of Default  hereunder  shall in any way be, or be
construed  to be, a waiver  of any  future  or  subsequent  Default  or Event of
Default.  The failure or delay of the Lessor in exercising  any right granted it
hereunder upon any occurrence of any of the contingencies set forth herein shall
not constitute a waiver of any such right upon the continuation or recurrence of
any such  contingencies  or  similar  contingencies  and any  single or  partial
exercise  of any  particular  right by the Lessor  shall not exhaust the same or
constitute a waiver of any other right provided herein.  To the extent permitted
by  Applicable  Law,  the Lessee  hereby  waives  any  rights  now or  hereafter
conferred by statute or otherwise which may require the Lessor to sell, lease or
otherwise  use the  Undivided  Interest or Unit 1 in  mitigation of the Lessor's
damages as set forth in paragraph  (a) of this Section 16 or which may otherwise
limit or modify any of the Lessor's rights and remedies provided in this
Section 16.

                  (d) Exercise of Other  Rights or Remedies.  In addition to all
other rights and  remedies  provided in this Section 16, the Lessor may exercise
any other right or remedy that may be  available to it under  Applicable  Law or
proceed by  appropriate  court  action to enforce the terms hereof or to recover
damages for the breach hereof.

                  (e)  Special  Cure Right of Lessee.  In the event a "Notice of
Default"  is given  under  Section 15 (iv),  the Lessee  may, on or prior to the
occurrence of an Event of Default  resulting  therefrom,  give written notice to
the Lessor  stating that the Lessee has elected to exercise the option (the Cure
Option)  provided in this Section 16(e),  which election shall be irrevocable as
to the  Lessee.  Promptly  after the giving of such  notice,  the Lessee and the
Owner  Participant shall agree upon the Fair Market Sales Value of the Undivided
Interest and the Real Property  Interest or, if they shall be unable so to agree
within one month  after the date of the  Lessee's  notice,  such value  shall be
determined  by the  Appraisal  Procedure.  On the Basic Rent  Payment  Date next
following the date that such Fair Market Sales Value shall have been determined,
the Lessee shall pay to the Lessor all Rent due on such Basic Rent Payment Date,
plus an amount  equal to the excess of (i) the greater of such Fair Market Sales
Value and the Casualty Value  determined as of such Basic Rent Payment Date over
(ii) the unpaid  principal  amount of the Notes  Outstanding  on such date after
giving effect to the payment,  if any, of the principal  installment and payable
on such  date.  Upon  compliance  in  full  by the  Lessee  with  the  foregoing
provisions  of  this  paragraph  (e) and  assumption  by the  Lessee  of all the
obligations  and  liabilities  of the Owner  Trustee under the Indenture and the
Notes pursuant to Section 3.9(b) of the Indenture, the Lessor shall Transfer the
Undivided  Interest and the Real Property  Interest to the Lessee. If the Lessee
shall not have assumed all the obligations and liabilities of the Owner

Trustee under the Indenture and the Notes in accordance  with Section  3.9(b) of
the Indenture,  but shall have paid all amounts  required by this paragraph (e),
the Lessor shall retain the Undivided  Interest and the Real  Property  Interest
subject  to the  terms  of  this  Facility  Lease  and  Section  7(b)(4)  of the
Participation Agreement; provided, however, that the obligation of the Lessee to

unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforce-ability  without invalidating the
remaining   provisions   hereof  or  thereof,   and  any  such   prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.  To the extent permitted
by  Applicable  Law, the Lessee hereby waives any provision of law which renders
any provision hereof prohibited or unenforceable in any respect.

                  (d) True  Lease.  This  Facility  Lease  shall  constitute  an
agreement of lease and nothing herein or therein shall be construed as conveying

additional  insured,  as its interest (or their  interests) may appear,  and any
policies  with  respect  to  nuclear  liability  insurance  with  respect to the
Undivided  Interest,  the Real Property  Interest,  Unit 1, or any part thereof,

however,  that if the Operating  Agent, as trustee,  shall become the loss payee
under any policy of insurance  constituting  Project Insurance,  then the Lessor
and the  Owner  Participant  shall  be and be made  beneficiaries  of the  trust
arrangement  under which the Operating Agent acts as trustee.  The Lessee shall,

that no premiums  are then  delinquent,  and (iii)  stating  that the  insurance
maintained by the ANPP  Participants with respect to PVNGS is in accordance with
the terms of (1) the ANPP Participation Agreement and (2) this Section 10, (B) a
report  signed by the  broker  or  brokers  for the  Lessee's  insurance  (of if

insurance (by coverage,  limits,  insureds and other pertinent details) required
to be maintained under the ANPP Participation Agreement. Any report with respect
to clause (A)(ii)(2) may be made in reliance upon a similar schedule provided by

the  Lessee  (a copy of  which  shall be  attached)  identifying  the  insurance
required to be maintained under this Section 10. All insurance  proceeds paid in
respect of damage,  destruction,  loss, theft or other casualty to the Undivided
Interest or the Real Property  Interest  shall be applied as provided in Section

immediately  prior to the  occurrence of such Nuclear  Incident,  the failure to
resume operation thereof as a result of such Nuclear Incident) if (A) the Period
of such cessation or failure equals or exceeds twenty-four  consecutive calendar
months,  or  (B)  such  Nuclear  Incident  causes  the  radiation  level  in the
containment  building  of Unit 1, as  measured  by the average of two high range
radiation  monitors in such containment  building of Unit 1 (or if only one such
monitor is  operating  at such  time,  such  monitor)  over one hour to equal or
exceed 500 rads per hour; provided, however, this subsection (B) shall not apply

Incident,  the failure to resume  operation  thereof as a result of such Nuclear
Incident)  if (A) the  Period of such  cessation  or  failure  equals or exceeds
thirty-six  consecutive calendar months; or (B) such Nuclear Incident causes the
radiation level in the containment building of the Affected Unit, as measured by
the average of two high range radiation  monitors in such  containment  building
(or if only one such monitor is operating at such time,  such  monitor) over one
hour to equal or exceed 500 rads per hour;  provided,  however,  this subsection
(B) shall not apply in respect of a Nuclear  Incident arising solely from a fuel
handling accident;

                  (5) the  occurrence  of a Nuclear  Incident  at Unit 1, 2 or 3

or (B) a discharge or dispersal of Source, Special Nuclear or Byproduct Material
from its intended  place of confinement in amounts off the PVNGS Site or causing
radiation  levels off the PVNGS Site such that, in the case of (B) above (x) the
NRC declares the occurrence of an Extraordinary  Nuclear  Occurrence or declares
any other event  connoting  an  equivalent  level of accident or (y) the surface
contamination  dose rate measured off the PVNGS Site by a radiation monitor at 1
meter  above  the  surface  level  equals  or is  greater  at any  time  than 10
millirads/hour (0.10  milligray/hour) or in the case of noble gas plume passage,
the radiation dose rate equals or is greater than 10 rads (0.10 gray) integrated
over 24 hours,  (or if the NRC  shall at any time  lower  the  radiation  levels
required for the occurrence of an Extraordinary  Nuclear Occurrence,  such lower
levels as shall be consistent with such change by the NRC); or

                  (6)  damage to or  destruction  of any  portion of Unit 1 and,
unless Lessee theretofore shall have exercised its purchase option under Section
13(b) of the Facility Lease, the failure of the Lessee, or of the Lessee and one
more other ANPP  Participants,  (A) to agree within eighteen  calendar months of
such damage or  destruction  (or prior to such  earlier  date as of which one or
more other ANPP  Participants  shall agree to restore or reconstruct any damaged
portion of Unit 1 in accordance with Section 16.2 of the ANPP Participation

6091.BURNHAMU1.DEBT.71:1

<PAGE>



Agreement) to restore or reconstruct Unit 1 to completion prior to the day sixty
calendar  months after the date of such agreement and (B) thereafter to complete
the restoration and  reconstruction  of Unit 1 within a period of sixty calendar
months after the date of such  agreement,  provided that no Final Shutdown shall
be deemed to have occurred  pursuant to this clause (6) if and so long as Unit 1
is in operation at a rated core power level of at least 1900 megawatts  thermal;
or

                  (7) the  non-operation of Unit 1 or the operation of Unit 1 at
a net rated power level below 630 megawatts electric or any combination  thereof
for any reason  (including,  without  limitation,  the occurrence of any Nuclear
Incident at any generating  facility located anywhere in the world) for a Period
of thirty-six  consecutive  calendar months (or a period through the penultimate
day of the Lease  Term if the Lessee  shall  have given  notice of its intent to
exercise the purchase  option  permitted by Section 13(b) of the Facility Lease)
other than as a result of damage to or destruction of Unit 1.

For purposes of this definition,  a Final Shutdown resulting from the occurrence
of an event  described  in  clause  (5) above  shall be deemed to have  occurred
immediately and automatically  upon the decline of the water coolant within Unit
1 to a level three feet above the nuclear fuel.

                  For purposes of the definition of "Final  Shutdown"  only, the
following  capitalized terms set forth therein shall have the following meanings
(other capitalized terms having the respective  meanings set forth in Appendix A
to the Facility Lease):

                  Extraordinary  Nuclear  Occurrence  shall have its  meaning as
defined in Section 11 of the Atomic Energy Act and the related NRC  regulations,
as amended to the date hereof, and as the meaning of such term shall be expanded
from time to time by future amendments thereof. The definition of "extraordinary
nuclear occurrence" contained in Section 11 of the Atomic Energy Act on the date
hereof is: "any event causing a discharge dispersal of source,  special nuclear,
or byproduct  material  from its place of  confinement  in amounts  offsite,  or
causing  radiation  levels  offsite,  which  the  Commission  determines  to  be


6091.BURNHAMU1.DEBT.71:1

<PAGE>



substantial,  and which the Commission  determines has resulted or will probably
result in  substantial  damages to  persons  offsite or  property  offsite.  Any
determination  by the  Commission  that such an event has, or has not,  occurred
shall be final and  conclusive,  and no other  official  or any court shall have
power or jurisdiction  to review any such  determination.  The Commission  shall
establish   criteria  in  writing  setting  forth  the  basis  upon  which  such
determination  shall be made. As used in this  subsection,  'offsite' means away
from 'the  location' or 'the  contract  location'  as defined in the  applicable
Commission  indemnity  agreement,  entered into pursuant to section 2210 of this
title."

                  Nuclear  Incident shall have its meaning as defined in Section
11 of the Atomic Energy Act, as amended to the date hereof and as the meaning of
such term may be expanded from time to time by future  amendments  thereof.  The
definition of "nuclear incident"  contained in the Atomic Energy Act on the date
hereof is: "any  occurrence,  including  an  extraordinary  nuclear  occurrence,
within the United States  causing,  within or outside the United States,  bodily
injury,  sickness,  disease, or death, or loss of or damage to property, or loss
of use of property,  arising out of or resulting  from the  radioactive,  toxic,
explosive,  or  other  hazardous  properties  of  source,  special  nuclear,  or
byproduct  material:  Provided,  however,  that as the  term is used in  section
2210(1) of this title, it shall include any such  occurrence  outside the United
States:  And provided  further,  That as the term is used in section  2210(d) of
this title,  it shall include any such  occurrence  outside the United States if
such occurrence  involves source,  special nuclear,  or byproduct material owned
by, and used by or under contract with, the United States: And provided further,
That as the term is used in section  2210(c) of this title, it shall include any
such  occurrence  outside  both the United  States and any other  nation if such
occurrence arises out of or results from the radioactive,  toxic,  explosive, or
other hazardous  properties of source,  special nuclear,  or byproduct  material
licensed  pursuant to subchapters  V, VI, VII, and IX of this chapter,  which is
used in  connection  with the operation of a licensed  stationary  production or
utilization facility or which moves outside the territorial limits of the United
States in transit from one person  licensed by the  Commission to another person
licensed by the Commission."

                  Period of a stated duration in respect of any event shall mean
an  indefinite  period which can  reasonably be expected to exceed the lesser of
such duration and the period remaining to the date which is three years prior to

                  For purposes of clause  (iii) of part (1) of this  definition,

Energy Act and the related NRC regulations,  as amended to the date hereof,  and
as the  meaning  of such  term  shall be  expanded  from  time to time by future
amendments  thereof.  The  definition  of  "extraordinary   nuclear  occurrence"
contained  in Section 11 of the Atomic  Energy Act on the date  hereof is:  "any
event causing a discharge or dispersal of source,  special nuclear, or byproduct
material from its intended place of confinement in amounts  offsite,  or causing
radiation levels offsite, which the Commission determines to be substantial, and
which  the  Commission  determines  has  resulted  or will  probably  result  in
substantial damages to persons offsite or property offsite. Any determination by
the Commission  that such an event has, or has not,  occurred shall be final and
conclusive,  and no other official or any court shall have power or jurisdiction
to review any such  determination.  The Commission  shall establish  criteria in
writing setting forth the basis upon which such determination  shall be made. As

used in this  subsection,  'offsite'  means  away  from 'the  location'  or 'the
contract location' as defined in the applicable  Commission indemnity agreement,
entered into pursuant to section 2210 of this title."

"Extraordinary  Nuclear Occurrence" shall have its meaning as defined in Section
11 of the Atomic Energy Act of 1954,  as amended to the Closing  Date;  the term
"Incipient  Extraordinary  Nuclear  Occurrence"  shall  mean an event  causing a
discharge or dispersal of nuclear source,  special nuclear or nuclear by-product
material from its intended  place of  confinement in amounts off site or on site
or causing a radiation  level off site or on site which an  independent  nuclear
consultant agreed to by the Lessee and the Owner Participant (or, failing prompt
agreement,  appointed by the American Arbitration  Association) determines to be
substantial  and which such  consultant  determines  has resulted in substantial
injury to persons on or off the PVNGS Site or substantial damage to property off
the PVNGS  Site;  and the term  "Nuclear  Incident"  shall  mean any  occurrence
causing  bodily  injury,  sickness,  disease  or death,  or loss of or damage to
property,  or the loss of use of property,  arising out of or resulting from the
radioactive,  toxic,  explosive or other hazardous properties of nuclear source,
special nuclear or nuclear by-product material.

                  For  purposes  of  parts  (4),   (5),  (6)  and  (8)  of  this
definition,  Nuclear Incident shall have its meaning as defined in Section 11 of
the Atomic  Energy Act, as amended to the date hereof and as the meaning of such
term  may be  expanded  from  time to time by  future  amendments  thereof.  The
definition of "nuclear incident"  contained in the Atomic Energy Act on the date
hereof is: "any  occurrence,  including  an  extraordinary  nuclear  occurrence,
within the United States  causing,  within or outside the United States,  bodily
injury,  sickness,  disease, or death, or loss of or damage to property, or loss
of use of property,  arising out of or resulting  from the  radioactive,  toxic,
explosive,  or  other  hazardous  properties  of  source,  special  nuclear,  or
byproduct  material:  Provided,  however,  that as the  term is used in  section
2210(1) of this title, it shall include any such  occurrence  outside the United
States:  And provided  further,  That as the term is used in section  2210(d) of
this title,  it shall include any such  occurrence  outside the United States if


6091.CHRYSLER.DEBT.71:1

<PAGE>


such occurrence  involves source,  special nuclear,  or byproduct material owned
by, and used by or under contract with, the United States: And provided further,
That as the term is used in section  2210(c) of this title, it shall include any
such  occurrence  outside  both the United  States and any other  nation if such
occurrence arises out of or results from the radioactive,  toxic,  explosive, or
other hazardous  properties of source,  special nuclear,  or byproduct  material
licensed  pursuant to subchapters  V, VI, VII, and IX of this chapter,  which is
used in  connection  with the operation of a licensed  stationary  production or
utilization facility or which moves outside the territorial limits of the United
States in transit from one person  licensed by the  Commission to another person
licensed by the Commission."

                  For  purposes  of parts (4),  (5) and (8) of this  definition,
Period of a stated  duration  in respect of any event  shall mean an  indefinite
period which can  reasonably  be expected to exceed the lesser of such  duration
and the period  remaining  to the date which is three  years prior to the end of
the  remaining  Basic Lease Term (or if such event  occurs  after the date three
years prior to the end of the  remaining  Basic  Lease  Term,  the lesser of six
months and the period  remaining to the day next  preceding the end of the Basic
Lease  Term) or a stated  period in excess of the  lesser  thereof  or an actual
period which continues in excess of the lesser thereof.

                  For purposes of part (6) of this definition,  Source,  Special
Nuclear or Byproduct  Material shall have their  respective  defined meanings as
defined in Section 11 of the Atomic  Energy Act of 1954,  as amended to the date
hereof and as the meanings of such terms may be
expanded by future amendments thereof.

         for the operation of such interest (a "Lessor's  Interest") acquired by
         the lessor in such  transaction,  such lessor shall entertain cash bids

                 AMENDMENT NUMBER EIGHT TO COAL SALES AGREEMENT
                 ----------------------------------------------


This Amendment Number Eight to Coal Sales Agreement  ("this  Amendment") is made
effective as of the 1st day of September,  1995 between SAN JUAN COAL COMPANY, a
Delaware  corporation  ("SJCC"),  PUBLIC  SERVICE  COMPANY OF NEW MEXICO,  a New
Mexico  corporation  and TUCSON ELECTRIC POWER COMPANY,  an Arizona  corporation
(collectively, "Utilities").


                                    RECITALS:


1.       SJCC and  Utilities  are parties to that certain  Coal Sales  Agreement
         dated August 18, 1980,  as amended and  supplemented  (the "CSA") which
         provides  for the delivery of coal to the San Juan  Generating  Station
         ("SJGS").

2.       The CSA  describes  specific  coal  sources  for  SJGS,  including  the
         Fruitland  Leases  and the La  Plata  Leases.  Under  the  terms of the
         various subleases and assignment agreements that give SJCC the right to
         mine coal from the Fruitland and La Plata Leases, SJCC and BHP Minerals
         International   Inc.  ("BHP")  are  obligated  to  make  the  following
         payments, among others, to third parties:

         a)       A Retained Economic Interest ("REI") is payable by BHP on each
                  ton of coal mined and delivered  from the Fruitland  Leases or
                  on an  Annual  Tonnage  (the "REI  Minimum"),  as set forth in
                  Article VI of the Sublease  between  Western Coal Co.  ("WCC")
                  and BHP (formerly  Utah  International  Inc.) dated August 18,
                  1980, as amended (the "BHP  Sublease"),  whichever is greater.
                  An amount  equal to the REI is  payable by SJCC to BHP on each
                  ton of coal  mined and  delivered  from the  Fruitland  Leases
                  under the  provisions  of the  Sublease  between  SJCC and BHP
                  dated August 18, 1980, as amended (the "SJCC Sublease").

         b)       An   Overriding    Royalty   and/or   Net   Profits   Interest
                  (collectively,  "NPI") is  payable by SJCC on each ton of coal
                  mined and  delivered  from the La Plata Leases or on a minimum
                  annual tonnage (the "NPI Minimum"),  whichever is greater, all
                  as set  forth  in the  Assignment  Agreement  between  WCC and
                  Cimarron  Coal Company dated October 30, 1979, as amended (the
                  "Assignment  Agreement").  The rights and  obligations  of WCC
                  under the Assignment Agreement were assigned to and assumed by
                  SJCC by Assignment of Leases dated November 24, 1981.

         c)       Under  the  terms of the  CSA,  Utilities  reimburse  SJCC for
                  amounts  equal to payments of REI made by SJCC pursuant to the
                  SJCC Sublease and for payments of NPI made by SJCC pursuant to
                  the Assignment Agreement.

3.       The parties wish to provide  flexibility  among coal sources,  with the
         objective  of lowering  the total  delivered  cost of coal to SJCS,  by
         providing  for payment by Utilities to SJCC of amounts  equal to REI or
         NPI payments made by BHP or SJCC, respectively, with respect to the REI
         Minimum or the NPI Minimum to the extent that lower cost coal  replaces
         coal  which  would  otherwise  have been mined and  delivered  from the
         Fruitland Leases and/or the La Plata Leases.

5.       SJCC will deliver Replacement Tons pursuant to mining plans approved by
         the Joint Committee  showing that the projected total cost to Utilities
         of Replacement  Tons is less than the projected total cost to Utilities
         for an  equal  number  of  tons  to be  delivered  under  then  current

         budgets shall be deemed to be part of the annual operating cost budget,
         and shall be subject to all of the  provisions of paragraph  12.3(a) of
         the CSA.

6.       Replacement Tons will be priced as follows:

         a)       Replacement  Tons mined from the South Lease Extension will be

         Extension and the La Plata Leases  without prior  approval by the Joint
         Committee   of   each   additional    source   of   Replacement   Tons.
         Notwithstanding  any  other  provision  of this  Amendment  or the CSA,
         decisions of the Joint  Committee  about  sources of  Replacement  Tons
         shall not be subject to arbitration.

         paragraph  9.3(b)  and  (c)  of  the  CSA  in  any  year  during  which
         Replacement tons are delivered will be the sum of

         a)       the  lesser of (i) the La Plata  Minimum or (ii) of the sum of
                  the Fruitland  Tons,  the La Plata Tons,  and the  Replacement
                  Tons mined and  delivered  during the year from sources  other
                  than the La Plata Leases (the "Total SJCC  Tons"),  multiplied

                  less the Capital  Investment  Element  payable for each ton of
                  coal transported from the La Plata Leases to SJGS in excess of
                  the La Plata  Minimum in any calendar  year under the terms of
                  paragraph  7.2(b)  of the  certain  Transportation  Agreement,

him the  execution  thereof,  or by an affidavit of a witness to such  execution
sworn to before any such notary or other such  officer and where such  execution
is by an officer of a corporation  or  association or a member of a partnership,
on behalf of such corporation,  association or partnership,  such certificate or
affidavit shall also constitute sufficient proof of his authority.  The fact and
date of the execution of any such instrument or writing, or the authority of the
Person  executing  the same,  may also be proved in any other  manner  which the
Trustee deems sufficient.

                  (c) The  ownership  of  Securities  shall  be  proved  by  the
Security Register.

                  (d) Any request,  demand,  authorization,  direction,  notice,
consent,  waiver or other  action by the Holder of any  Security  shall bind the

                  SECTION 1.015.  Notices, etc., to Trustee, PNM and Company.

                  Any  request,  demand,   authorization,   direction,   notice,
consent,  waiver or Act of Holders or other  document  provided or  permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder, by the Company, by PNM or by an
         Authorized  Agent shall be sufficient  for every  purpose  hereunder if
         made,  given,  furnished  or filed in writing to or with the Trustee at
         its Corporate Trust Office, or

                  (2) the Company by the Trustee, by any Holder, by PNM or by an
         Authorized Agent shall be sufficient for every purpose  hereunder if in
         writing  and  mailed,  first-class  postage  prepaid,  to  the  Company
         addressed to it at the address of its principal office specified in the
         first paragraph of this  instrument or at any other address  previously
         furnished  in writing to the  Trustee  and PNM by the  Company for such
         purpose, or

                  (3) PNM by the Trustee, by any Holder, by the Company or by an
         Authorized Agent shall be sufficient for every purpose  hereunder if in
         writing and mailed, first-class postage prepaid, to PNM addressed to it
         at the address of its principal office specified in the first paragraph
         of this  instrument  or at any other  address  previously  furnished in
         writing to the Trustee and the Company by PNM for such purpose.

                  SECTION 1.016.  Notices to Holders; Waiver.

                  Where  this  Indenture  provides  for notice to Holders of any
event,  such  notice  shall  be  sufficiently  given  (unless  otherwise  herein
expressly  provided) if in writing and mailed,  first-class  postage prepaid, to
each Holder,  at his address as it appears in the Security  Register,  not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice.  Where this Indenture  provides for notice in any manner,
such  notice may be waived in writing by the  Person  entitled  to receive  such
notice,  either  before  or  after  the  event,  and  such  waiver  shall be the
equivalent of such notice.  Waivers of notice by Holders shall be filed with the
Trustee,  but such filing shall not be a condition  precedent to the validity of
any action  taken in  reliance  upon such  waiver.  In any case where  notice to
Holders  is given by mail,  neither  the  failure to mail such  notice,  nor any
defect in any  notice so  mailed,  to any  particular  Holder  shall  affect the
sufficiency of such notice with respect to other  Holders,  and any notice which
is mailed in the manner herein provided shall be  conclusively  presumed to have
been duly given.

                  SECTION 1.017.  Conflict with Trust Indenture Act.

                  If any provision  hereof  limits,  qualifies or conflicts with
another  provision  hereof which is required to be included in this Indenture by
any of the  provisions  of the  TIA,  such  required  provision  shall  control.
Notwithstanding  the foregoing,  the provisions of the TIA contained in Sections
9.08, 9.13 and 10.03 shall not become  operative under this Indenture until this
Indenture shall have been qualified under the TIA.

                  SECTION 1.018.  Effect of Heading and Table of Contents.

                  The  Article  and  Section  headings  herein  and the Table of
Contents are for convenience only and shall not affect the construction hereof.

                  SECTION 1.019.  Successors and Assigns.

                  All covenants,  agreements,  representations and warranties in
this Indenture by the Trustee, PNM and the Company shall bind and, to the extent
permitted  hereby,  shall  inure to the benefit of and be  enforceable  by their
respective successors and assigns, whether so expressed or not.

                  SECTION 1.10.  Separability Clause.

                  In case any provision in this  Indenture or in the  Securities
shall  be  invalid,  illegal  or  unenforceable,   the  validity,  legality  and
enforceability  of the remaining  provisions shall not in any way be affected or
impaired thereby.

                  SECTION 1.11.  Benefits of Indenture.

                  Nothing in this Indenture or in the  Securities,  expressed or
implied,  shall  give to any  Person,  other than the  parties  hereto and their
successors hereunder, the Holders of Securities,  and the Lessors and the Equity
Investors as expressly  provided  herein,  any benefit or any legal or equitable
right, remedy or claim under this Indenture.

                  SECTION 1.12.  Governing Law.

                  This  Indenture  and each  Security  are  being  executed  and
delivered in the State of New York, shall be deemed to be contracts made in such
State and for all purposes shall be construed in accordance with and governed by
the laws of the State of New York.

                  SECTION 1.13.  Legal Holidays.

                  In any case where the Redemption  Date or the Stated  Maturity
of any  Security or of any  installment  of  interest,  or any date on which any
defaulted  interest is proposed to be paid,  shall not be a Business  Day,  then
(notwithstanding  any other  provision  of this  Indenture)  payment of interest
and/or principal (and premium, if any) need not be made on such date, but may be
made on the next  succeeding  Business  Day with the same force and effect as if
made on the Redemption Date or at the Stated  Maturity,  or on the date on which
the defaulted  interest is proposed to be paid, and no interest shall accrue for
the period from and after such Redemption Date or Stated  Maturity,  or date for
the payment of defaulted interest, as the case may be.

                                   ARTICLE II.

                  SECTION 1.001.  Forms Generally.

                  The  Securities  of each  series  shall  be in the  form  (not
inconsistent  with this Indenture) as shall be established in one or more Series
Supplemental  Indentures,   in  each  case  with  such  appropriate  insertions,
omissions,  substitutions  and  other  variations  in and to  such  form  as are
required or  permitted  by this  Indenture  and may have  imprinted or otherwise
reproduced thereon such legend or legends,  not inconsistent with the provisions
of this  Indenture,  as may be required to comply with any law or with any rules
or regulations pursuant thereto, or with any rules of any securities exchange or
to conform to general usage, all as may be determined by the officers  executing
such Securities, as evidenced by their execution thereof.

                  SECTION 1.002.  Form of Trustee's Authentication.

                  SECTION  1.003.   Amount   Unlimited;   Issuable   in  Series;
                  Limitations on Issuance.

                  The  aggregate  principal  amount of  Securities  which may be
authenticated and delivered under this Indenture is unlimited. Securities may be
issued  hereunder up to the aggregate  principal  amount which may be authorized
from time to time by the Board of Directors of the Company.

                  The terms of any series of  Securities  relative to payment of
principal  thereof,  and  premium  (if  any)  and  interest  thereon,  need  not
correspond  exactly to the schedule for such payments under the related  Pledged
Lessor Notes.

                  The  Securities  may be  issued in one or more  series.  There
shall be established in one or more Series Supplemental Indentures, prior to the
issuance of Securities of any series,

                  (1) the title of the  Securities  of the series  (which  shall
         distinguish the Securities of the series from all other Securities) and

                  (2) any  limit  upon the  aggregate  principal  amount  of the
         Securities of such series that may be authenticated and delivered under
         this Indenture (except for Securities  authenticated and delivered upon
         registration  of, transfer of, or in exchange for, or in lieu of, other
         Securities of such series pursuant to Section 2.07, 2.08, 2.09, 6.06 or
         11.07);

                  (3) the date or dates on which the principal of the Securities
         of such series is payable;

                  (4) the rate or rates at which the  Securities  of such series
         shall  bear  interest,  or the  method  by  which  such  rate  shall be
         determined,  the date or dates from which such  interest  shall accrue,
         the interest  payment dates on which such interest shall be payable and
         the record dates for the  determination  of Holders to whom interest is
         payable;

                  (5)      the place or places where the principal and interest 
         on Securities of such series shall be payable (if other than as
         provided in Section 5.02);

                  (6) the price or prices at which, the period or periods within
         which and the terms and conditions upon which Securities of such series
         may be  redeemed,  in whole or in part,  at the option of the  Company,
         pursuant to any sinking fund or otherwise;

                  (7) the obligation, if any, of the Company to redeem, purchase
         or repay  Securities  of such series  pursuant  to any sinking  fund or
         analogous provisions or at the option of a Holder thereof and the price
         or prices at which and the period or periods within which and the terms
         and conditions  upon which  Securities of the series shall be redeemed,
         purchased or repaid, in whole or in part, pursuant to such obligation;

                  (8) if other than  denominations  of $1,000  and any  multiple
         thereof,  the denominations in which Securities of such series shall be
         issuable;

                  (9) any other terms of such series  (which  terms shall not be
         inconsistent with the provisions of this Indenture); and

                  (10) any trustees, authenticating or paying agents, warrant 
         agents, transfer agents or registrars with respect to the Securities of
         such series;

provided,  however, that, after giving effect to the issuance of a new series of
the  Securities  and the subjection to the Lien of this Indenture of the related
Pledged Lessor Notes,  the average of the daily balance of Excess Funds for each
fiscal year of the Company  shall not exceed 10% of the average of the aggregate
principal amount of Securities  Outstanding on each day in such fiscal year. For
purposes of the  foregoing  proviso,  "Excess  Funds"  shall mean,  for any day,
amounts actually paid to the Trustee under the Pledged Lessor Notes in excess of
amounts then due and payable in respect of Securities.

                  SECTION 1.004.  Authentication and Delivery of Securities.

                  At any time and from  time to time  after  the  execution  and
delivery of this  Indenture,  the Company may deliver  Securities  of any series
executed  by the  Company to the Trustee  for  authentication,  together  with a
Company Order for the  authentication  and delivery of such Securities,  and the
Trustee shall thereupon  authenticate  and deliver such Securities in accordance
with  such  Company  Order,  without  any  further  action  by the  Company.  In
authenticating  such  Securities and accepting the  additional  responsibilities
under this  Indenture  in  relation  to such  Securities  the  Trustee  shall be
entitled to receive,  and (subject to Section 9.01) shall be fully  protected in
relying upon:

                  (1)      an executed Series Supplemental Indenture;

                  (2) an Officers'  Certificate of the Company (a) certifying as
         to  resolutions of the Board of Directors of the Company by or pursuant
         to which the terms of the  Securities of such series were  established,
         (b) certifying  that all conditions  precedent  under this Indenture to
         the Trustee's  authentication and delivery of such Securities have been
         complied  with and (c)  certifying  that (x) the terms of the documents
         referred to in clauses (3) and (4) below are not inconsistent  with the
         terms of this Indenture as then and  theretofore  supplemented  and (y)
         such documents comply with Exhibit A hereto (if applicable);

                  (3) fully executed counterparts (but not the original thereof)
         of (a) the Lease  Indentures under which were issued the Pledged Lessor
         Notes relating to such series of Securities and (b) the Leases relating
         to such Pledged Lessor Notes;

                  (4)  the original of the Pledged Lessor Notes relating to such
         series of Securities;

                  (5)  signed  copies,   either  addressed  to  the  Trustee  or
         accompanied by statements  that the Trustee may rely on such documents,
         of all certificates and opinions of counsel delivered to the Company in
         connection with its purchase  pursuant to the applicable  participation
         Agreements  of the  Pledged  Lessor  Notes  relating  to such series of
         Securities and, to the extent not covered by such opinions, Opinions of
         Counsel (x) to the effect that:  (a) the form or forms and the terms of
         such  Securities  have  been  established  by  a  Series   Supplemental
         Indenture as permitted by Sections 2.01 and 2.03 in conformity with the
         provisions of this Indenture;  (b) such Securities,  when authenticated
         and  delivered  by the  Trustee and issued by the Company in the manner
         and subject to any  conditions  specified  in such  Opinion of Counsel,
         will constitute valid and binding  obligations of the Company;  and (c)
         all laws and  requirements  in respect of the execution and delivery by
         the Company of the Securities have been complied with; and (y) covering
         such other matters as the Trustee may reasonably request; and

                  (6) duly executed Extension Letters relating to the Pledged 
         Lessor Notes;

provided,  however, that if a series of Securities is to be authenticated by the
Trustee in advance of the actual  delivery to the Trustee of the Pledged  Lessor
Notes relating  thereto,  (X) the documents  described in the foregoing  clauses
(2)(c),  (3), (4), (5) (other than the opinion  described in subclauses  (x) and
(y)) and (6) need not be delivered in connection with

#30122041.1
                                       12

such  authentication,  but shall be delivered in connection  with the release of
the  proceeds  of the sale of such  series  of  Securities  in  accordance  with
Sections  2.15 and  13.01  hereof  and (Y) the form of the  Series  Supplemental
Indenture  shall be  appropriately  modified to reflect the later  delivery  and
pledge of the related Pledged Lessor Notes.

                  Receipt by the Trustee of the Officer's  Certificate  referred
to in clause (2) above shall be  conclusively  presumed for all purposes of this
Indenture to  establish  that the Lease  Indentures,  the Leases and the Pledged
Lessor Notes referred to in such  certification  comply with the requirements of
Exhibit A hereto.

                  The  Trustee  shall have the right to decline to  authenticate
and deliver any Securities  under this Section if the Trustee,  being advised by
counsel, determines that such action may not lawfully be taken by the Company or
if the  Trustee in good faith by its board of  directors  or board of  trustees,
executive  committee,  or a trust  committee  of  directors  or trustees  and/or
responsible  officers shall  determine that such action would expose the Trustee
to personal liability.

                  SECTION 1.005.  Form and Denominations.

                  The Securities of each series shall be in registered  form and
may have such letters, numbers or other marks of identification and such legends
or endorsements printed, lithographed or engraved thereon, as may be required to
comply with the rules of any  securities  exchange or to conform to any usage in
respect thereof, or as may, consistently herewith, be prescribed by the Board of
Directors  of the Company or by the officers  executing  such  Securities,  such
determination by said officers to be evidenced by their signing the Securities.

                  The definitive  Securities  shall be printed,  lithographed or
engraved or  produced  by any  combination  of these  methods on steel  engraved
borders or may be produced  in any other  manner  permitted  by the rules of any
securities   exchange,   all  as  determined  by  the  officers  executing  such
Securities, as evidenced by their execution of such Securities.

                  All  Securities  of any  one  series  shall  be  substantially
identical  except as to  denomination  and  Stated  Maturity  and  except as may
otherwise be provided  herein or in the Series  Supplemental  Indenture  setting
forth the terms of the Securities of such series.

                  SECTION 1.006.  Execution of Securities.

                  The  Securities  shall be executed on behalf of the Company by
its President or one of its Vice Presidents  under its corporate seal reproduced
thereon and attested by its Secretary or one of its Assistant  Secretaries.  The
signature of any such officers on the Securities may be manual or facsimile.

                  Securities  bearing  the  manual or  facsimile  signatures  of
individuals  who  were at the time  such  signatures  were  affixed  the  proper
officers  of the  Company  shall  bind the  Company,  notwithstanding  that such
individuals  or any of them  have  ceased  to hold  such  offices  prior  to the
authentication  and delivery of such  Securities or did not hold such offices at
the date of such Securities.

                  SECTION 1.007.  Temporary Securities.

                  Pending  the  preparation  of  definitive  Securities  of  any
series,  the Company  may  execute,  and upon  Company  Order the Trustee  shall
authenticate and deliver, temporary Securities of such series which are printed,
lithographed,   typewritten,   photocopied   or  otherwise   produced,   in  any
denomination, substantially of the tenor of the definitive Securities in lieu of
which  they  are  issued  and  with  such  appropriate  insertions,   omissions,
substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

         If  temporary  Securities  of any series are issued,  the Company  will
cause definitive  Securities of such series to be prepared without  unreasonable
delay.  After the  preparation  of  definitive  Securities  of such series,  the
temporary  Securities  of such  series  shall  be  exchangeable  for  definitive
Securities of such series upon surrender of the temporary Securities  of such

#30122041.1
                                       13

<PAGE>

series at the office or agency of the Company, for such purpose, in the Place of
Payment,  without charge to the Holder.  Upon surrender for  cancellation of any
one or more temporary Securities of any series the Company shall execute and the
Trustee shall  authenticate  and deliver in exchange  therefor a like  aggregate
principal  amount  of  definitive   Securities  of  such  series  of  authorized
denominations.  Until so exchanged such temporary Securities of any series shall
in all  respects  be  entitled  to the same  benefits  under this  Indenture  as
definitive Securities of such series.

                  SECTION 1.008.  Registration, Transfer and Exchange.

                  The  Trustee  shall  cause to be kept at the  Corporate  Trust
Office a  register  in which,  subject  to such  reasonable  regulations  as the
Company  may  prescribe,  the Company  shall  provide  for the  registration  of
Securities and of  registration  of transfers and exchanges of Securities.  This
register and, if there shall be more than one Security  Registrar,  the combined
registers  maintained  by all such  Security  Registrars,  are herein  sometimes
referred to as the "Security Register".

                  Upon surrender for registration of transfer of any Security of
any series at the Corporate Trust Office,  or at any office or agency maintained
for such purpose pursuant to Section 9.14(a), the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or  transferees,  one or more new  Securities of the same series and of the same
Stated  Maturity for  principal and interest and of a like  aggregate  principal
amount.

                  At the option of the Holders,  Securities of any series may be
exchanged  for an equal  aggregate  principal  amount of  Securities of the same
series and of the same Stated  Maturity  for  principal  and interest and of any
authorized  denominations,  upon  surrender of the Securities to be exchanged at
the  Corporate  Trust  Office,  or at any office or agency  maintained  for such
purpose pursuant to Section 9.14(a).  Whenever any Securities are so surrendered
for  exchange,  the  Company  shall  execute,  and  the  Trustee  or  any  other
Authenticating  Agent shall  authenticate and deliver,  the Securities which the
Securityholder making the exchange is entitled to receive.

                  All  Securities  issued  upon  any  transfer  or  exchange  of
Securities  shall be the valid  obligations of the Company,  evidencing the same
debt,  and entitled to the same security and benefits under this  Indenture,  as
the Securities surrendered upon such transfer or exchange.

                  Every Security  presented or surrendered  for  registration of
transfer or exchange  shall be duly  endorsed,  or be  accompanied  by a written
instrument  of transfer in form  satisfactory  to the Security  Registrar,  duly
executed by the Holder thereof or his attorney duly authorized in writing.

                  No service  charge  shall be required  of any  Securityholders
participating  in any  transfer  or exchange  of  Securities  in respect of such
transfer or exchange,  but the Security  Registrar may require  payment of a sum
sufficient to cover any tax or other governmental  charge that may be imposed in
connection  with any transfer or exchange of  Securities,  other than  exchanges
pursuant to Sections 2.07, 6.06 or 11.07 not involving any transfer.

                  The  Security  Registrar  shall not be required  (i) to issue,
transfer or exchange any Security of any series during a period beginning at the
opening  of  business  15 days  before  the day of the  mailing  of a notice  of
redemption of Securities of such series  selected for  redemption  under Section
6.02 or 7.02 and ending at the close of business on the day of such mailing,  or
(ii) to transfer or exchange any Security so selected for redemption in whole or
in part except the unredeemed portion of any Security selected for redemption in
part.

                  SECTION   1.009. Mutilated,   Destroyed,   Lost   and   Stolen
                  Securities.

                  If (i) any mutilated  Security is  surrendered to the Trustee,
or the Company, the Security Registrar and the Trustee receive evidence to their
satisfaction of the destruction,  loss or theft of any Security,  and (ii) there
is  delivered  to the  Company,  to the  Security  Registrar  and to the Trustee
evidence to their  satisfaction of the ownership and authenticity  thereof,  and
such  security  or  indemnity  as may be  required  by them to save each of them
harmless,  then,  in the  absence  of notice  to the  Company,  to the  Security
Registrar or to the Trustee that such Security has been acquired by a bona fide

purchaser,  the Company  shall  execute  and upon its request the Trustee  shall
authenticate  and  deliver,  in exchange  for or in lieu of any such  mutilated,
destroyed,  lost or stolen Security,  a new Security of like tenor and principal
amount, bearing a number not contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has  become  or is about to  become  due and  payable,  the  Company  may,  upon
satisfaction  of the  conditions  set  forth  in  clauses  (i)  and  (ii) of the
preceding paragraph, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section,  the
Security  Registrar may require the payment of a sum sufficient to cover any tax
or other  governmental  charge that may be imposed in  relation  thereto and any
other expenses connected therewith.

                  Every new Security  issued pursuant to this Section in lieu of
any destroyed,  lost or stolen Security shall constitute an original  additional
contractual  obligation of the Company,  whether or not the  destroyed,  lost or
stolen  Security  shall be at any  time  enforceable  by  anyone,  and  shall be
entitled  to all the  security  and  benefits  of  this  Indenture  equally  and
proportionately with any and all other Securities duly issued hereunder.

                  The  provisions  of  this  Section  are  exclusive  and  shall
preclude (to the extent  lawful) all other  rights and remedies  with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

                  SECTION 1.10.  Payment of Interest; Interest Rights Preserved.

                  Interest on any Security  which is payable,  and is punctually
paid or duly provided for, at any Stated  Maturity of an installment of interest
shall  be paid  to the  Person  in  whose  name  that  Security  (or one or more
Predecessor  Securities)  is  registered at the close of business on the Regular
Record Date for such interest. At the option of the Company, payment of interest
on any  Security  may be made by  check  mailed  to the  address  of the  Person
entitled thereto as such address shall appear in the Security Register.

                  Any  interest on any  Security of any series which is payable,
but is not  punctually  paid or duly provided for, at any Stated  Maturity of an
installment of interest shall forthwith cease to be payable to the Holder on the
relevant  Regular  Record  Date by virtue of having been such  Holder;  and such
defaulted interest may be paid by the Company,  at its election in each case, as
provided in paragraph (1) or paragraph (2) below:

                  (1) The  Company  may elect,  which  election  shall be at the
         direction  of any Lessor  whose  Pledged  Lessor  Note is in default in
         respect of the payment of interest and who is proposing to make payment
         of all or part of  such  defaulted  interest,  to make  payment  of any
         defaulted interest to the Persons in whose names the Securities of such
         series in respect of which interest is in default (or their  respective
         Predecessor  Securities)  are  registered at the close of business on a
         Special Record Date for the payment of such defaulted  interest,  which
         shall be fixed in the  following  manner.  Such Lessor shall notify the
         Trustee  and the Paying  Agent in  writing  of the amount of  defaulted
         interest  proposed to be paid on each such Security and the date of the
         proposed  payment,  and at the same time there shall be deposited  with
         the Trustee an amount of money equal to the aggregate  amount  proposed
         to be paid in respect of such defaulted interest or there shall be made
         arrangements  satisfactory to the Trustee for such deposit prior to the
         date of the proposed  payment,  such money when deposited to be held in
         trust  for the  benefit  of the  Persons  entitled  to  such  defaulted
         interest as in this paragraph provided. Thereupon the Trustee shall fix
         a Special Record Date for the payment of such defaulted  interest which
         shall be not more  than 15 nor less  than 10 days  prior to the date of
         the proposed payment and not less than 10 days after the receipt by the
         Trustee  of the  notice of the  proposed  payment.  The  Trustee  shall
         promptly notify the Company and the Security  Registrar of such Special
         Record Date and, in the name and at the expense of the  Company,  shall
         cause notice of the proposed payment of such defaulted interest and the
         Special Record Date therefor to be mailed, first class postage prepaid,
         to each  holder  of a  Security  of such  series at his  address  as it
         appears in the Security  Register,  not less than 10 days prior to such
         Special Record Date.  Notice of the proposed  payment of such defaulted
         interest and the

<PAGE>



         Special  Record Date  therefor  having been mailed as  aforesaid,  such
         defaulted  interest  shall be paid to the  Persons  in whose  names the
         Securities of such series (or their respective Predecessor  Securities)
         are  registered  on such  Special  Record  Date and  shall no longer be
         payable pursuant to the following paragraph (2).

                  (2) The Company may make, or cause to be made,  payment of any
         defaulted interest in any other lawful manner not inconsistent with the
         requirements  of any  securities  exchange on which the  Securities  in
         respect of which  interest is in default  may be listed,  and upon such
         notice as may be required by such  exchange,  if, after notice given by
         the Company to the  Trustee of the  proposed  payment  pursuant to this
         paragraph, such payment shall be deemed practicable by the Trustee.

                  Subject to the  foregoing  provisions  of this  Section,  each
Security  delivered  under this Indenture upon transfer of or in exchange for or
in lieu of any other  Security  shall carry the rights to  interest  accrued and
unpaid, and to accrue, which were carried by such other Security,  and each such
Security  shall bear  interest  from  whatever  date shall be  necessary so that
neither gain nor loss in interest shall result from such  transfer,  exchange or
replacement.

                  SECTION 1.11.  Persons Deemed Owners.

                  Prior to due  presentment for  registration  of transfer,  the
Person in whose name any Security is registered  shall be deemed to be the owner
of such  Security  for the purpose of  receiving  payment of  principal  of (and
premium,  if any),  and (subject to Section 2.10) interest on, such Security and
for all other  purposes  whatsoever,  whether or not such  Security  be overdue,
regardless of any notice to anyone to the contrary.

                  SECTION 1.12.  Cancellation.

                  All Securities  surrendered  for payment,  redemption,  credit
against any Sinking Fund  payment or  redemption  payment,  transfer or exchange
shall, if surrendered to any Person other than the Trustee,  be delivered to the
Trustee for cancellation. The Company may at any time deliver to the Trustee for
cancellation any Securities  previously  authenticated  and delivered  hereunder
which the Company may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly cancelled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture.  All cancelled
Securities  held by the Trustee  shall be destroyed and  certification  of their
destruction  delivered to the Company unless,  by Company  Request,  the Company
otherwise directs.

                  SECTION 1.13.  Dating of Securities; Authentication.

                  Each  Security  of any  series  shall be dated the date of the
original  issuance of the  Securities of such series by the Company,  which date
shall be specified by the Company in the Company Order  delivered to the Trustee
pursuant to Section  2.04 in  connection  with the original  authentication  and
delivery of the  Securities of such series.  No Security  shall be secured by or
entitled to any benefit under this  Indenture or be valid or obligatory  for any
purpose unless there appears on such Security a certificate  of  authentication,
in the form provided for herein, executed by the Trustee by the manual signature
of one of its Responsible Officers, and such certificate upon any Security shall
be conclusive evidence, and the only evidence,  that such Security has been duly
authenticated and delivered hereunder.

                  SECTION 1.14.  Source of Payments;  Rights and  Liabilities of
                  Lessors and Equity Investors.

                  All payments of principal and premium (if any) and interest to
be made under the  Securities  and this  Indenture  (other than payments made in
connection  with an  optional  redemption  by a Lessor)  shall be made only from
assets subject to the lien of this Indenture or the income and proceeds received
by the Trustee therefrom.  Each Holder, by its acceptance of a Security,  agrees
that (x) it will look solely to the assets subject to the lien of this Indenture
or the income and  proceeds  received  by the  Trustee  therefrom  to the extent
available for distribution to such Holder as herein provided and (y) none of any
Equity  Investor,  any  Lessor,  any Lease  Indenture  Trustee or the Trustee is
liable to any Holder or, in the case of any  Equity  Investor,  Lessor and Lease
Indenture Trustee, to the Trustee for any amounts payable under any Security or,

except as provided  herein with respect to the Trustee,  for any liability under
this Indenture. An Equity Investor,  Lessor or Lease Indenture Trustee shall not
have any duty or  responsibility  under this  Indenture or the Securities to any
Holder or to the Trustee.

                  SECTION 1.15. Sale of Securities;  and Application of Proceeds
from the Sale of Securities.

                  (a) Promptly  upon receipt by the Company of the proceeds from
any sale of a series of the Securities,  the Company shall deposit such proceeds
with the  Trustee.  The funds so  deposited  shall be held by the  Trustee  in a
separate account as part of the Pledged Property and shall be invested,  applied
and distributed by the Trustee as provided herein.

                  (b)  Subject  to the  provisions  of Section  13.01,  upon the
issuance of the Pledged Lessor Notes related to any series of Securities and the
delivery  thereof to the Trustee to be subjected  to the Lien of this  Indenture
pursuant to a Series Supplemental Indenture, the Trustee shall pay to the Lessor
obligated in respect of any such Pledged  Lessor Note,  out of funds held by the
Trustee in such  separate  account as Pledged  Property,  an amount equal to the
principal  amount of such Pledged Lessor Note in respect of which such Lessor is
obligated. All payments to be made by the Trustee to any Lessor shall be made in
immediately available funds at the respective offices designated by such Lessor.

coupon  bonds which it may receive as part of the  Pledged  Property,  or it may
cause the same to be  exchanged  for  registered  bonds  without  coupons of any
denomination. The Trustee may cause to be transferred into its name, as Trustee,
or into the  name of its  nominee,  any and all  registered  bonds  which it may
receive as part of the Pledged  Property,  or may cause such registered bonds to
be exchanged for coupon bonds.  All Pledged Lessor Notes assigned to and pledged
with the  Trustee  pursuant to any  provision  of this  Indenture  or any Series

by proper instruments of assignment  satisfactory to the Trustee,  duly executed
by the Company. The Company will deliver promptly to the Trustee such documents,
certificates  and opinions as the Trustee may  reasonably  request in connection
with  subjection of any  securities to the Lien of this  Indenture to the extent
contemplated hereby.

                  SECTION 1.002.  Disposition of Payments on Pledged Property.

Indenture  Trustee to take or refrain from taking any action which  holders of a
Pledged  Lessor  Note have the option to direct and (ii) how to vote any Pledged
Lessor Note if a vote has been called for with respect thereto. In addition, any
Securityholder  may at any time request the Trustee to direct, or to participate

Trustee may do so under such Lease Indenture. In directing any action or casting
any vote as the holder of a Pledged  Lessor Note,  the Trustee  shall specify to
the Lease  Indenture  Trustee the  principal  amount of the Pledged  Lessor Note
which is in favor of the action or vote,  the  principal  amount of the  Pledged
Lessor Note which is opposed to the action or vote, and the principal  amount of
the Pledged Lessor Note which is not taking any position for the action or vote.
Such  principal  amounts shall be determined by allocating  the total  principal
amount of the Pledged Lessor Note with respect to which  direction was requested

                  SECTION  1.021.  Payment of  Principal,  Premium  (if any) and

                  The Company  will  maintain in the Borough of  Manhattan,  The
City of New York,  an office or agency  where  Securities  may be  presented  or
surrendered  for payment,  where  Securities may be surrendered  for transfer or
exchange  and where  notices  and  demands to or upon the  Company in respect of
Securities and this Indenture may be served. PNM will give prompt written notice
to the Trustee of the location,  and of any change in the location, of each such
office or agency.  If at any time the Company  shall fail to  maintain  any such
office or agency or the Company or PNM shall fail to furnish  the  Trustee  with
the address thereof, such presentations,  surrenders, notices and demands may be
made or served at the  Corporate  Trust Office of the  Trustee,  and the Company
hereby  appoints  the  Trustee  its  agent to  receive  all such  presentations,
surrenders, notices and demands.

Trust.
                  All moneys deposited with the Trustee or with any Paying Agent
for the purpose of paying the  principal  of or premium,  if any, or interest on
Securities  shall be deposited  and held in trust for the benefit of the Holders
of the  Securities  entitled to such  principal,  premium,  if any, or interest,
subject to the provisions of this Section. Moneys so deposited and held in trust
shall not be a part of the  Pledged  Property  but shall  constitute  a separate
trust fund for the benefit of the Holders of the relevant Securities.

                  The Company may at any time,  for the purpose of obtaining the
satisfaction  and discharge of this Indenture or for any other purpose,  pay, or
direct any Paying  Agent to pay,  to the  Trustee all sums held in trust by such
Paying Agent,  such sums to be held by the Trustee upon the same trusts as those
upon which such sums were held by such Paying  Agent;  and, upon such payment by
any Paying  Agent to the Trustee,  such Paying Agent shall be released  from all
further liability with respect to such money.

                  Any money  deposited  with the Trustee or any Paying  Agent in
trust for the payment of the principal of or premium, if any, or interest on any
Security and  remaining  unclaimed for three years (or such lesser period as may
be  required  by law to give  effect to this  provision)  after such  principal,
premium or interest  has become due and payable  shall be paid to the Company on
Company  Request  (to the extent such monies  shall have been  deposited  by the
Company) or to any other  Person on its request (to the extent such monies shall
have been deposited by such other Person); and the Holder of such Security shall
thereafter,  as an unsecured general creditor,  look only to the Company or such
other  Person,  to the extent such monies shall have been paid to the Company or
such other Person, as the case may be, for payment thereof, and all liability of
the  Trustee or such  Paying  Agent  with  respect  to such  trust  money  shall
thereupon  cease;  provided,  however,  that the Trustee or such  Paying  Agent,
before  being  required  to make any such  repayment,  may at the expense of the
Company  or, to the extent such  monies are to be paid to another  Person,  such
other  Person  cause to be mailed to each such  Holder  notice  that such  money
remains unclaimed and that, after a date specified  therein,  which shall not be
less than 30 days from the date of such mailing,  any unclaimed  balance of such
money then remaining will be repaid to the Company or such other Person.

                  The Company, at its own cost and expense,  will do or cause to

permitted in this Indenture;  provided,  however,  that the Company shall not be
required to preserve  any right or  franchise  if the Board of  Directors of the
Company shall determine that the preservation  thereof is no longer desirable in
the conduct of the  business  of the  Company  and that the loss  thereof is not
disadvantageous in any material respect to the Securityholders.

                  SECTION 1.025.  Protection of Pledged Property.

                  The Company and PNM will from time to time execute and deliver
all such  supplements and amendments  hereto and all such financing  statements,
continuation statements, instruments of further assurance, and other instruments
necessary to

                           (v) preserve and defend  title to any  Securities  or
                  other  instrument  included  in the Pledged  Property  and the
                  rights of the  Trustee,  and of the  Securityholders,  in such
                  Securities  or other  instrument  against  the  claims  of all

         respect  to  matters  arising  under  any  such  Principal  Instrument,
         provided,  in each  instance,  that such  action  shall not  materially
         adversely affect the interests of Holders of Securities; or

                  (2) to add to the covenants  and  agreements of the parties to
         such Principal  Instrument other covenants and agreements  hereafter to

         rights and  interests,  subject to such  liens,  restrictions  or other
         encumbrances, if any, as shall be therein specifically described; or

                  (7) in the case of a Lease  Indenture,  to  enable  the  Lease
         Indenture  Trustee  thereunder to confer upon holders of Pledged Lessor
         Notes any additional rights,  remedies,  powers or authorities that may
         lawfully be granted or conferred upon such holders; or

         made  without  the  consent of or notice to the  holders of the related
         Pledged Lessor Notes; or

                  (11) to provide for the  issuance of Lessor  Notes in addition
         to the Pledged Lessor Notes  relating to such Principal  Instruments in
         accordance  with the  applicable  provisions  of the related  Principal
         Instruments.

                  (c) No Change with respect to a Principal Instrument,  whether
effected  pursuant  to  subsection  (a) or pursuant  to  subsection  (b) of this
Section 5.09, and anything in such subsections or elsewhere in this Indenture to
the contrary  notwithstanding,  shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                  (1) except as provided in any Lease, change such Lease in such
         a way as to  change  the  timing  or  reduce  the  amount  of any Lease
         Payment, or otherwise to release, except as provided in such Lease, PNM
         from its  obligation  under  such  Lease in respect of payment of Lease
         Payments; or

                  (2) modify,  amend or supplement the Participation  Agreements
         in such a way as to,  or give any  consent,  waiver,  authorization  or
         approval  which  would,  release any Equity  Investor  from its payment
         obligations contained in said Participation Agreements.

                  (d)  Except  during  the  continuance  of an Event of  Default
hereunder,  upon request of the Company or PNM, the Trustee shall consent to any
Change  described  in this  Section  5.09,  and  shall  execute  any  instrument
requested  by the  Company  or PNM,  as the  case  may be,  for the  purpose  of
confirming  such  consent,  but only upon receipt by the Trustee of an Officers'
Certificate and an Opinion of Counsel of the Company or PNM, as the case may be,
each stating that such Change is authorized by this Indenture and that execution
of such  instrument is appropriate  to confirm such consent,  unless such Change
adversely  affects  the  Trustee's  rights,  duties  or  immunities  under  this
Indenture or otherwise,  in which case the Trustee may, in its  discretion,  but
shall not be  obligated  to, give such  consent  and the Trustee  shall be fully
protected in relying on such Officers' Certificate and Opinion of Counsel.

                  SECTION 1.10.  Annual Statement as to Compliance.

                  (a) PNM and the Company each will  deliver to the Trustee,  on
or  before  120  days  after  the end of each of its  fiscal  years,  a  written
statement  (which need not comply with Section  1.02) signed by its President or
one of  its  Vice  Presidents  and by  its  Treasurer  or one of its  Assistance
Treasurers or its Comptroller or one of its Assistant Comptrollers,  stating, as
to each signer thereof, that

                  (1) a review of the  activities of PNM or the Company,  as the
         case may be,  required  during such year of PNM or the Company,  as the
         case may be, under this Indenture has been made under his  supervision;
         and

                  (2) to the best of his knowledge, based on such review, PNM or
         the  Company,  as the case may be, has  fulfilled  all its  obligations
         under this  Indenture  throughout  such  year,  or, if there has been a
         default in the fulfillment of any such obligation, specifying each such
         default known to such officer and the nature and status thereof.

                  (b) PNM and the  Company  each will  deliver  to the  Trustee,
promptly after having  obtained  knowledge  thereof,  but in no event later than
five days  thereafter,  written  notice of any event  which  with the  giving of
notice or lapse of time, or both, would become an Event of Default under Section
8.01.

                                   ARTICLE II.

                            REDEMPTION OF SECURITIES

                  The  provisions of this Article Six shall be applicable to the
Securities of any series which are  redeemable  before their Stated  Maturity of
principal  except  as  otherwise  provided  in  such  Securities  or the  Series
Supplemental Indenture with respect thereto as contemplated by Section 2.03.

                  SECTION 1.001.  Notice to Trustee of Redemption.

                  In case of any  redemption  of any  Securities  of any  series
otherwise than through the operation of an applicable  Sinking Fund, the Company
shall, at least 45 days prior to the scheduled Redemption Date (unless a shorter
notice shall be satisfactory  to the Trustee),  notify the Trustee in writing of
such Redemption Date and of the principal amount of Securities of such series to
be redeemed.

                  SECTION  1.002.  Selection  by  Trustee  of  Securities  to be
Redeemed.

                  If  fewer  than all the  Securities  of any  series  are to be
redeemed,  other than through the operation of an applicable  Sinking Fund,  the
particular  Securities of such series to be redeemed shall be selected following
receipt by the Trustee of the notice required by Section 6.01, but not more than
60 days prior to the  Redemption  Date,  by the  Trustee,  from the  Outstanding
Securities of such series not previously  called for redemption,  by such method
as the  Trustee  shall deem fair and  appropriate  and which may provide for the
selection  for  redemption  of portions of the  principal of  Securities  of any
denomination  larger  than  $1,000;  provided,  however,  that for  purposes  of
selecting  Securities  of any series for  redemption  pursuant to this  Section,
Securities  of such  series  shall be  redeemed  from each  Stated  Maturity  of
principal  of  Securities  of  such  series  as  nearly  as  practicable  in the
proportion that the aggregate  principal  amount of Securities of such series of
such  Stated  Maturity  of  principal  Outstanding   immediately  prior  to  the
Redemption  Date shall bear to the aggregate  principal  amount of Securities of
such series of all Stated Maturities of principal then Outstanding, in each case
taking  into  account  in  the  determination  of  Securities   Outstanding  the
Securities of such series subject to such redemption; provided further, however,
that when  Securities  are being redeemed  pursuant to any  applicable  optional
(rather than  mandatory)  redemption  provisions,  the Securities to be redeemed
shall be  selected  solely from the  Securities  of the series and of the Stated
Maturity of principal in respect of which a Company Order has been received.  If
Securities are to be selected for any redemption  pursuant to this Section,  the
Trustee  may make  such  adjustments  as it  shall  deem  necessary  so that the
principal amount of Securities  redeemed shall be $1,000 or an integral multiple
thereof,  such  adjustments  to be made by the  Trustee  in such  manner  as the
Trustee in its sole discretion deems appropriate.

                  The  Trustee  shall  promptly  notify the  Company,  PNM,  the
Security  Registrar and the Paying Agent in writing of the  Securities  selected
for redemption and, in the case of any Security selected for partial redemption,
the principal amount thereof to be redeemed.

                  For  all  purposes  of  this  Indenture,  unless  the  context
otherwise  requires,  all  provisions  relating to the  redemption of Securities
shall  relate,  in the case of any Security  redeemed or to be redeemed  only in
part, to the portion of the  principal of such Security  which has been or is to
be redeemed.

                  SECTION 1.003.  Notice of Redemption.

                  Notice  of  redemption   (including   redemption  through  the
operation of any applicable  Sinking Fund) shall be given by  first-class  mail,
postage  prepaid,  mailed  not less than 20 nor more  than 60 days  prior to the
Redemption  Date, to each Holder of  Securities  to be redeemed,  at his address
appearing in the Security Register. All notices of redemption shall state:


#30122041.1
                                       24

<PAGE>

                  (1) the Redemption Date,

                  (2) the Redemption Price,

                  (3) if fewer than all Outstanding Securities of any series are
         to be  redeemed,  the  identification  (and,  in the  case  of  partial
         redemption,   the  respective  principal  amounts)  of  the  particular
         Securities,  including the series and the Stated  Maturity of principal
         of such Securities, to be redeemed,

                  (4) that on the  Redemption  Date the  Redemption  Price  will
         become  due and  payable  upon each such  Security,  and that  interest
         thereon shall cease to accrue from and after said date,

                  (5) the place where such  Securities are to be surrendered for
         payment of the Redemption Price, and

                  (6) that the  redemption is through the operation of a Sinking
         Fund, if such is the case.

                  Notice of redemption  of  Securities  to be redeemed  shall be
given by the Trustee in the name of the Company.

                  SECTION 1.004.  Deposit of Redemption Price.

                  Prior to any Redemption  Date,  the Company shall deposit,  or
cause to be  deposited,  with the Paying Agent an amount of money  sufficient to
pay the Redemption  Price of all the Securities which are to be redeemed on that
date.

                  SECTION 1.005.  Securities Payable on Redemption Date.

                  Notice of  redemption  having  been  given as  aforesaid,  the
Securities  so to be redeemed  shall,  on the  Redemption  Date,  become due and
payable at the corporate trust office of the Paying Agent (or, if such office is
not in the Borough of Manhattan,  the City of New York, at either such office or
an office to be  maintained  in such  Borough) at the  Redemption  Price therein
specified  and from and after such date (unless  there shall be a default in the
payment of the Redemption  Price) such Securities  shall cease to bear interest.
Upon surrender of such Securities for redemption in accordance with said notice,
such Securities shall be paid at the Redemption Price,  exclusive,  however,  of
installments of interest maturing on or prior to the Redemption Date, payment of
which  shall  have  been  made  or  duly  provided  for to the  Holders  of such
Securities  registered  as such on the  relevant  Record  Dates,  or  otherwise,
according to their terms and the provisions of Section 2.10.

                  If any  Security  called for  redemption  shall not be so paid
upon  surrender  thereof for  redemption,  the principal  (and premium,  if any)
shall,  until paid,  continue to bear interest from the  Redemption  Date at the
rate borne by the Security in respect of overdue payments.

                  SECTION 1.006.  Securities Redeemed in Part.

                  Any  Security  which is to be  redeemed  only in part shall be
surrendered  at the  corporate  trust  office of the Paying  Agent (or,  if such
office is not in the Borough of Manhattan,  the City of New York, at either such
office or an office to be maintained in such Borough) (with due  endorsement by,
or a  written  instrument  of  transfer  in form  satisfactory  to the  Security
Registrar duly executed by, the Holder  thereof or his attorney duly  authorized
in writing) and the Company shall execute and the Trustee shall authenticate and
deliver to the Paying  Agent for  delivery to the Holder of such  Security a new
Security  or  Securities  of the same  series and the same  Stated  Maturity  of
principal,  of any  authorized  denomination  as  requested  by such  Holder  in
aggregate  principal amount equal to and in exchange for the unredeemed  portion
of the principal of the Security so surrendered.

                                  SINKING FUNDS

                  SECTION 1.011.  Sinking Funds for Securities.

                  [(a)] The amount of any sinking fund  payment  provided for by
the terms of  Securities  of any series (and any Stated  Maturity  of  principal
within a series)  is herein  referred  to as a "Sinking  Fund",  and the date on
which a Sinking Fund  payment is to be made is herein  referred to as a "Sinking
Fund Date." Each such Sinking Fund payment shall be applied to the redemption of
Securities of the  appropriate  series and the  appropriate  Stated  Maturity of
principal on the appropriate Sinking Fund Date.

                  [(b)] In the event  that  there  shall  have been any  partial
redemption  of a series of  Securities  (other than  pursuant  to an  applicable
Sinking  Fund),  the  amount  of  each  applicable  Sinking  Fund  payment  of a
particular  Stated Maturity of principal  within such series  subsequent to such
redemption  shall be reduced by an amount  equal to the amount  obtained  by (i)
multiplying  the amount of such Sinking Fund payment with respect to such Stated
Maturity of  principal as in effect  prior to such  redemption  by a fraction of
which the  numerator  shall be the aggregate  principal  amount of Securities of
such  Stated  Maturity  of  such  series  redeemed   pursuant  to  such  partial
redemption,  and the  denominator  shall be the  aggregate  principal  amount of
Securities of such Stated Maturity of such series Outstanding  immediately prior
to such redemption, and (ii) rounding the amount indicated in (i) to the nearest
$1,000,  subject  to  necessary  adjustment  so that the  total  amount  of such
reduction is equal to the total principal amount of Securities redeemed pursuant
to such partial  redemption,  such  adjustment to be made by the Trustee in such
manner as the Trustee in its sole discretion deems appropriate.

                  [(c)]  Pursuant  to  the  Series  1986A  Series   Supplemental
Indenture dated as of July 15, 1986 (the Series 1986A  Supplement),  the Company
issued a series of Securities  designated  "Lease Obligation Bonds Series 1986A"
(the  Series A  Bonds),  of  which,  on June 1, 1994 two  Stated  Maturities  of
principal remain outstanding:  July 15, 1996 and January 15, 2014. Paragraph (b)
of Section 7.01 of the Original  Indenture to the contrary  notwithstanding,  in
the event that there shall have been any partial redemption of Series A Bonds of
a particular  Stated  Maturity of principal  (other than pursuant to the Sinking
Fund),  the Sinking  Fund  payments  thereafter  to be made with respect to such
Series A Bonds shall be adjusted as follows.  The Company  shall first  identify
all  related  Pledged  Lessor  Notes (as  defined in Article II of Series  1986A
Supplement and identified in Schedule 2 thereto) having the same maturity as the
Series A Bonds of such particular Stated Maturity of principal redeemed, if any,
which are outstanding  following such redemption;  provided,  however,  that for
purposes of this Section 7.01(c),  any such Pledged Lessor Notes with a maturity
subsequent to January 15, 2010 shall be deemed to have a maturity of January 15,
2014.  Having  identified  all  such  outstanding   Pledged  Lessor  Notes  (the
Outstanding Notes), the Company shall determine the dates on which the principal
of such Outstanding Notes is to be amortized (the Scheduled Amortization Dates).
The amount of the Sinking Fund payment scheduled to be made on each Sinking Fund
Date subsequent to the date of such partial redemption shall then be adjusted to
equal the aggregate  principal  amount of all Outstanding  Notes scheduled to be
amortized on the Scheduled  Amortization Date corresponding to such Sinking Fund
Date. All such adjustments in respect of Sinking Fund payments on a Sinking Fund
Date shall be rounded to the nearest  $1,000,  and shall be subject to necessary
further  adjustment so that the total amount of such reduction is at least equal
to the  total  principal  amount  of Series A Bonds  redeemed  pursuant  to such
partial redemption.  Having made the calculations  required by the preceding two
sentences,  the Company shall deliver to the Trustee a Company Request not later
than 30 days  following  any partial  redemption  of Series A Bonds  (other than
pursuant to the Sinking  Fund),  setting  forth (x) the  schedules  of principal
amortization  of all related  Outstanding  Notes having the same maturity as the
Stated  Maturity of principal  of the Series A Bonds  redeemed and (y) a revised
schedule of Sinking Fund  payments  applicable to Series A Bonds having the same
Stated  Maturity of  principal as the Series A Bonds  redeemed.  The Trustee may
rely on such  Company  Request  and  shall  have no  duty  with  respect  to the
adjustments  set forth therein other than to make them  available for inspection
by a Holder  of  Series A Bonds at the  Corporate  Trust  Office  uponreasonable
notice.]2

                  SECTION  1.012.  Selection  by  Trustee  of  Securities  to be
Redeemed Through Operation of Sinking Fund.

                  In the case of Securities to be redeemed through  operation of
the Sinking Fund, the particular  Securities to be redeemed shall be selected no
more  than 60 days nor less  than 30 days  prior to the  Redemption  Date by the
Trustee  from the  outstanding  Securities  of the same  series  and of the same
Stated Maturity of principal not previously  called for redemption by prorating,
as nearly as may be, the principal amount of Securities to be redeemed among the
Holders of  Securities  of the same  series and of the same  Stated  Maturity of
principal  registered in their  respective  names. In any proration  pursuant to
this  Section,  the  Trustee  shall  make such  adjustments,  reallocations  and
eliminations as it shall deem proper so that the principal  amount of Securities
so prorated shall be $1,000 or an integral  multiple  thereof,  by increasing or
decreasing or  eliminating  the amount which would be allocable to any Holder on
the basis of exact proportion by an amount not exceeding $1,000.  The Trustee in
its discretion may determine the particular  Securities of a Stated  Maturity of
principal  registered  in the name of any Holder  which are to be  redeemed,  in
whole or in part.

                  Notwithstanding the provisions of the preceding paragraph, if,
at the time of any such  selection,  there  shall be any  Holders  of less  than
$1,000,000  aggregate  principal amount of Outstanding  Securities of the series
and of the Stated Maturity of principal to be so redeemed,  the selection of the
particular Securities to be so redeemed shall be made in the following manner:

                  (a) the Trustee shall first  prorate the  principal  amount of
Securities of such series and of such Stated Maturity to be so redeemed  between
(i) Holders of Securities in aggregate  principal  amounts of $1,000,000 or more
and (ii)  Holders of  Securities  in  aggregate  principal  amounts of less than
$1,000,000;  such  proration to be effected in  accordance  with the  respective
aggregate  principal  amounts of such Securities held by the Holders referred to
in the foregoing items (i) and (ii), respectively;

                  (b) the Trustee shall then select for redemption in the manner
hereinabove  in the first  paragraph  of this Section  7.02  provided,  from the
Securities of such series and Stated Maturity held by the Holders referred to in
item (i) of clause (a) above, particular Securities (or portions thereof) in the
principal amount prorated to such Holders pursuant to said clause (a); and

                  (c) the Trustee shall then select for redemption in the manner
provided in Section 6.02 hereof,  from the  Securities of such series and Stated
Maturity  held by the  Holders  referred  to in item  (ii) of said  clause  (a),
particular  Securities (or portions thereof) in the principal amount prorated to
such Holders pursuant to said clause (a);

provided,  however, in any such prorating pursuant to this paragraph the Trustee
may,  according to such method as it shall deem proper in its  discretion,  make
such  adjustments by increasing or decreasing by not more than $1,000 the amount
which  would  be  allocable  on the  basis  of an  exact  proportion,  as may be
necessary  to the end that the  principal  amount so  prorated  shall be in each
instance an integral multiple of $1,000.

                  SECTION  1.022.  Acceleration  of  Maturity;   Rescission  and
Annulment.

                  Upon the occurrence of an Event of Default,  (i) if such Event
of Default is one  referred  to in clause  (1),  (2),  (3),  (4),  (6) or (7) of
Section 8.01, the Trustee may, and upon the direction of the Holders of not less
than 25% in principal  amount of the Securities  Outstanding  shall, and (ii) if
such  Event of  Default is the one  referred  to in clause  (5) of Section  8.01
(including  without  limitation  an event of default  under any Lease  which has
resulted  in an Event of  Default  referred  to in clause  (1),  (2),  or (3) of
Section 8.01), the Trustee shall, declare the principal of all the Securities to
be due and payable  immediately,  by a notice in writing to PNM and the Company,
and upon any such  declaration  such principal shall become  immediately due and
payable;  provided that no such  declaration  shall be made (and no action under
Section  8.03 or 8.05  shall be taken) in cases in which the Event of Default is
one  referred  to in clause  (1),  (2),  or (3) of Section  8.01 which  resulted
directly from a failure of PNM to make any payment of rent under any Lease until
such time as the  Lessor  under such  Lease has been  given the  opportunity  to
exercise its rights,  if any,  under  provisions of the related Lease  Indenture
analogous to Section 6.8 of the Lease Indentures dated as of December 16, 1985.

                  At any time after such a declaration of acceleration  has been
made and before any sale of the Pledged  Property,  or any part  thereof,  shall
have been made  pursuant to any power of sale as  hereinafter  in this  Article;
provided,  the  Holders  of a majority  in  principal  amount of the  Securities
Outstanding,  by written notice to the Company and the Trustee,  may rescind and
annul such declaration and its consequences if

                  (1)  there  shall  have  been  paid to or  deposited  with the
         Trustee a sum sufficient to pay

                           (A)  all  overdue  installments  of  interest  on all
                  Securities,

                           (B) the  principal of (and  premium,  if any, on) any
                  Securities  which  have  become  due  otherwise  than  by such
                  declaration  of  acceleration  and  interest  thereon  at  the
                  respective  rates provided in the Securities for late payments
                  of principal or premium,

                           (C) to the extent  that  payment of such  interest is
                  lawful,  interest upon overdue installments of interest at the
                  respective  rates provided in the Securities for late payments
                  of interest, and

                           (D)  all  sums  paid  or   advanced  by  the  Trustee
                  hereunder   and   the   reasonable   compensation,   expenses,
                  disbursements  and  advances  of the  Trustee,  its agents and
                  counsel; and

                  (2) all Events of Default,  other than the  non-payment of the
         principal  of   Securities   which  have  become  due  solely  by  such
         acceleration, have been cured or waived as provided in Section 8.08.

No such  rescission  shall  affect  any  subsequent  default or impair any right
consequent  thereon.  [and  no  such  annulment  shall  take  place  unless  all
declarations of acceleration of all Pledged Lessor Notes  theretofore given have
also  been  annulled  in  accordance  with  the  terms of the  applicable  Lease
Indentures.]3

                  [Notwithstanding anything in this Section to the contrary, the
Trustee  shall  rescind any  acceleration  of maturity of the  principal  of and
interest  on the  Securities  as a  consequence  of an  Event of  Default  which
resulted  from an event of  default  under any Lease  and  which  resulted  in a
declaration of acceleration of the Pledged Lessor Notes issued under the related
Lease Indenture, if the declaration of acceleration of such Pledged Lessor Notes
has been rescinded in accordance  with the terms of such Lease Indenture and the
conditions set forth in paragraphs (1) and (2) of this Section have been met.]4

                  SECTION 1.023.  Trustee's  Power of Sale of Pledged  Property;
Notice Required; Power to Bring Suit.

                  If an Event of Default shall have occurred and be  continuing,
subject to the provisions of Sections 8.06 and 8.07 and the proviso to the first
paragraph  of Section  8.02,  the  Trustee,  by such  officer or agent as it may
appoint, may:

                  (1) sell, to the extent  permitted by law,  without  recourse,
         for cash,  or credit or for other  property,  for  immediate  or future
         delivery, and for such price or prices and on such terms as the Trustee
         in its discretion may determine,  the Pledged  Property as an entirety,
         or in any such  portions  as the  Holders  of a majority  in  aggregate
         principal amount of the Securities then Outstanding shall request by an
         Act of  Securityholders,  or, in the  absence of such  request,  as the
         Trustee in its  discretion  shall deem expedient in the interest of the
         Securityholders, at public or private sale; and/or

                  (2) proceed by one or more suits,  actions or  proceedings  at
         law or in equity or otherwise or by any other  appropriate  remedy,  to
         enforce  payment of the  Securities  or  Pledged  Lessor  Notes,  or to
         foreclose  this  Indenture  or to sell  the  Pledged  Property  under a
         judgment or decree of a court or courts of competent  jurisdiction,  or
         by the  enforcement  of any such other  appropriate  legal or equitable
         remedy,  as the  Trustee,  being  advised by  counsel,  shall deem most
         effectual  to protect and enforce any of its rights or powers or any of
         the rights or powers of the Securityholders.

                  In the event that the Trustee  shall deem it advisable to sell
any of or all the Pledged  Property in  accordance  with the  provisions of this
Section,  PNM and the Company  agree that if  registration  of any such  Pledged
Property shall be required, in the opinion of counsel for the Trustee, under the
Securities  Act of 1933 or other  applicable  law, and  regulations  promulgated
thereunder,  and  if PNM  shall  not  effect,  or  cause  to be  effected,  such
registration  promptly,  the  Trustee  may sell any such  Pledged  Property at a
private  sale,  and no Person shall attempt to maintain that the prices at which
such Pledged Property is sold are inadequate by reason of the failure to sell at
public sale, or hold the Trustee liable therefor.

                  SECTION 1.024.  Incidents of Sale of Pledged Property.

                  Upon any sale of all or any part of the Pledged  Property made
either under the power of sale given under this  Indenture or under  judgment or
decree  in any  judicial  proceedings  for  foreclosure  or  otherwise  for  the
enforcement of this Indenture, the following shall be applicable:

                  (1) Securities Due and Payable. The principal of, and premium,
         if any, and accrued interest on, the Securities, if not previously due,
         shall immediately become and be due and payable.

                  (2) Trustee Appointed Attorney of Company to Make Conveyances.
         The  Trustee  is  hereby  irrevocably  appointed  the true  and  lawful
         attorney of the Company,  in its name and stead,  to make all necessary
         deeds,  bills  of sale  and  instruments  of  assignment,  transfer  or
         conveyance of the property thus sold;  and for that purpose the Trustee
         may execute all such documents and  instruments  and may substitute one
         or more persons with like power;  and the Company  hereby  ratifies and
         confirms  all  that  its  said   attorneys,   or  such   substitute  or
         substitutes, shall lawfully do by virtue hereof.

                  (3) Company to Confirm Sales and Conveyances.  If so requested
         by the  Trustee  or by any  purchaser,  the  Company  shall  ratify and
         confirm any such sale or transfer by executing  and  delivering  to the
         Trustee or to such purchaser or purchasers  all proper deeds,  bills of
         sale, instruments of assignment, conveyance or transfer and releases as
         may be designated in any such request.

                  (4) Securityholders and Trustee May Purchase Pledged Property.
         Any  Securityholder  or the Trustee may bid for and purchase any of the
         Pledged Property, and upon compliance with the terms of sale, may hold,
         retain,  possess and dispose of such Pledged Property in his or its own
         absolute right without further accountability.

                  (5) Purchaser at Sale May Apply  Securities to Purchase Price.
         Any  purchaser  at any such sale may,  in paying  the  purchase  price,
         deliver  any of the  Securities  then  Outstanding  in lieu of cash and
         apply to the purchase price the amount which shall,  upon  distribution
         of the net proceeds of such sale, after application to the costs of the
         action  and any other sums which the  Trustee is  authorized  to deduct
         under this  Indenture,  be payable on such  Securities  so delivered in
         respect of principal, premium, if any, and interest. In case the amount
         so  payable  on such  Securities  shall  be less  than the  amount  due
         thereon, duly executed and authenticated  Securities shall be delivered
         in  exchange  therefor  to the Holder  thereof  for the  balance of the
         amount due on such Securities so delivered by such Holder.

                  (6) Receipt of Trustee Shall Discharge Purchaser.  The receipt
         of the  Trustee  or of the  officer  making  such sale  under  judicial
         proceedings  shall be a sufficient  discharge to any  purchaser for his
         purchase  money,  and,  after paying such Purchase  money and receiving
         such receipt, such purchaser or his personal  representative or assigns
         shall not be obliged to see to the  application of such purchase money,
         or  be  in  any  way   answerable  or  any  loss,   misapplication   or
         non-application thereof.

                  (7) Sale To Divest  Rights of Company in  Property  Sold.  Any
         such sale  shall  operate to divest  the  Company of all right,  title,
         interest,  claim  and  demand  whatsoever,  either  at law or in equity
         otherwise,  in and to the  Pledged  Property  so sold,  and  shall be a
         perpetual  bar  both at law and in  equity  or  otherwise  against  the

         claiming or who may claim the Pledged  Property sold or any part hereof

         collected  by the Trustee  upon any sale made either under the power of
         sale  given  by this  Indenture  or under  judgment  or  decree  in any
         judicial  proceedings  for foreclosure or otherwise for the enforcement
         of this Indenture, shall be applied as provided in Section 8.12.

                  SECTION 1.025.  Judicial Proceedings Instituted by Trustee

                  [ (a) Trustee  May Bring Suit.  If there shall be a failure to
make payment of the  principal  of any  Security at its Stated  Maturity or upon
declaration of acceleration, call for redemption or otherwise, or of any Sinking
Fund payment when due and payable by the terms hereof or of such Security, or if
there shall be a failure to pay the premium, if any, or interest on any Security
when the same  becomes due and payable,  then the  Trustee,  if any such failure
shall continue for 15 days, in its own name, and as trustee of an express trust,
shall be entitled,  and empowered  subject to the proviso to the first paragraph
of Section 8.02 to institute any suits, actions or proceedings at law, in equity
or  otherwise,  for  the  collection  of the  sums  so  due  and  unpaid  on the
Securities,  and may prosecute any such claim or proceeding to judgment or final
decree, and may enforce any such judgment or final decree and collect the moneys
adjudged or decreed to be payable in any manner provided by law,  whether before
or after or during the pendency of any  proceedings  for the  enforcement of the
Lien of this Indenture,  or of any of the Trustee's  rights or the rights of the
Securityholders under this Indenture, and such power of the Trustee shall not be
affected by any sale  hereunder or by the exercise of any other right,  power or
remedy  for the  enforcement  of the  provisions  of this  Indenture  or for the
foreclosure of the lien hereof.

                  (b)  Trustee  May Recover  Unpaid  Indebtedness  after Sale of
Pledged  Property.  In the  case of a sale of the  Pledged  Property  and of the
application  of the  proceeds  of such sale to the  payment of the  indebtedness
secured by this  Indenture,  the  Trustee in its own name,  and as trustee of an
express trust, shall be entitled and empowered, by any appropriate means, legal,
equitable or otherwise,  to enforce  payment of, and to receive all amounts then
remaining due and unpaid upon, all or any of the Securities,  for the benefit of
the Holders thereof,  and upon any other portion of the  indebtedness  remaining
unpaid, with interest at the rates specified in the respective Securities on the
overdue  principal  of and  premium,  if any, and (to the extent that payment of
such interest is legally enforceable) on the overdue installments of interest.

                  (c)  Recovery  of  Judgment  Does  Not  Affect  Lien  of  this
Indenture or Other  Rights.  No recovery of any such judgment or final decree by
the Trustee and no levy of any execution under any such judgment upon any of the
Pledged  Property,  or upon any other  property,  shall in any  manner or to any
extent affect the Lien of this  Indenture upon any of the Pledged  Property,  or
any rights,  powers or remedies of the Trustee, or any liens, rights,  powers or
remedies of the Securityholders, but all such liens, rights, powers and remedies
shall continue unimpaired as before.

                  (d) Trustee May File Proofs of Claim;  Appointment  of Trustee
as Attorney-in-Fact in Judicial Proceedings.  The Trustee in its own name, or as
trustee of an express trust, or as attorney-in-fact for the Securityholders,  or
in any one or more of such capacities  (irrespective of whether the principal of
the  Securities  shall  then be due  and  payable  as  therein  expressed  or by
declaration or otherwise and irrespective of whether the Trustee shall have made
any demand for the payment of overdue principal,  premium (if any) or interest),
shall be entitled and empowered to file such proofs of claim and other papers or
documents  as may be  necessary  or advisable in order to have the claims of the
Trustee  and of the  Securityholders  (whether  such  claims  be based  upon the
provisions  of the  Securities  or of this  Indenture)  allowed  in any  equity,
receivership, insolvency, bankruptcy, liquidation, readjustment,  reorganization
or any other judicial  proceedings relative to the Company or any obligor on the
Securities  (within the meaning of the TIA), the creditors of the Company or any
such obligor,  the Pledged  Property or any other property of the Company or any
such obligor and any receiver, assignee, trustee,  liquidator,  sequestrator (or
other similar official) in any such judicial  proceeding is hereby authorized by
each  Securityholder  to make such payments to the Trustee and in the event that
the  Trustee  shall  consent  to the  making of such  payments  directly  to the
Securityholders,  to pay to the Trustee any amount due to it for the  reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel.  The Trustee is hereby  irrevocably  appointed  (and the successive
respective  Holders of the Securities,  by taking and holding the same, shall be
conclusively  deemed  to have so  appointed  the  Trustee)  the true and  lawful
attorney-in-fact of the respective  Securityholders,  with authority to (i) make
and file in the respective  names of the  Securityholders  (subject to deduction
from  any  such  claims  of  the  amounts  of  any  claims  filed  by any of the
Securityholders  themselves),  any claim,  proof of claim or amendment  thereof,
debt, proof of debt or amendment thereof, petition or other document in any such
proceedings  and to receive  payment  of any  amounts  distributable  on account
thereof,  (ii) execute any such other papers and documents and to do and perform
any and all such acts and things for and on behalf of such  Securityholders,  as
may be  necessary or  advisable  in order to have the  respective  claims of the
Trustee and of the Securityholders  against the Company or any such obligor, the
Pledged  Property  or any other  property  of the  Company  or any such  obligor
allowed in any such  proceeding  and (iii)  receive  payment of or on account of
such  claims  and  debt;  provided,  however,  that  nothing  contained  in this
Indenture  shall be deemed to give to the Trustee any right to accept or consent
to any plan of  reorganization  or otherwise  by action of any  character in any
such  proceeding to waive or change in any way any right of any  Securityholder.
Any moneys  collected  by the  Trustee  under this  Section  shall be applied as
provided in Section 8.12.

                  (e) Trustee Need Not Have Possession of Securities. All rights
of action  and of  asserting  claims  under this  Indenture  or under any of the
Securities  enforceable  by the Trustee  may be enforced by the Trustee  without
possession of any of such  Securities or the production  thereof at the trial or
other proceedings relative thereto.

                  (f) Suit To Be Brought for Ratable Benefit of Securityholders.
Any suit,  action or other proceeding at law, in equity or otherwise which shall
be instituted by the Trustee under any of the provisions of this Indenture shall
be for the equal, ratable and common benefit of all the Securityholders, subject
to the provisions of this Indenture.

                  (g) Trustee May Be Restored to Former  Position  and Rights in
Certain  Circumstances.  In case the Trustee shall have proceeded to enforce any
right  under  this  Indenture  by  suit,   foreclosure  or  otherwise  and  such
proceedings  shall have been  discontinued or abandoned for any reason, or shall
have been determined adversely to the Trustee, then in every such case, PNM, the
Company  and  the  Trustee  shall  be  restored  without  further  act to  their
respective former positions and rights hereunder,  and all rights,  remedies and
powers of the  Trustee  shall  continue as though no such  proceedings  had been
taken.
                  SECTION  1.026.  Securityholders  May  Demand  Enforcement  of
Rights by Trustee.

                  If an  Event of  Default  shall  have  occurred  and  shall be
continuing,  the Trustee  shall,  upon the  written  request of the Holders of a
majority in aggregate  principal  amount of the Securities then  Outstanding and
upon the offering of indemnity  as provided in Section  9.03(e),  but subject in
all  cases to the  provisions  of  Section  3.03 and the  proviso  to the  first
paragraph of Section 8.02,  proceed to institute  one or more suits,  actions or
proceedings  at law,  in equity  or  otherwise,  or take any  other  appropriate
remedy, to enforce payment of the principal of, or premium,  if any, or interest
on, the  Securities or Pledged Lessor Notes or to foreclose this Indenture or to
sell the  Pledged  Property  under a judgment  or decree of a court or courts of
competent  jurisdiction or under the power of sale herein granted,  or take such
other  appropriate  legal,  equitable or other  remedy,  as the  Trustee,  being
advised by counsel,  shall deem most effectual to protect and enforce any of the
rights  or  powers  of the  Trustee  or the  Securityholders,  or,  in case such
Securityholders  shall have requested a specific method of enforcement permitted
hereunder,  in the manner  requested,  provided  that such  action  shall not be
otherwise than in accordance with law and the provisions of this Indenture,  and
the  Trustee,  subject  to such  indemnity  provisions,  shall have the right to
decline to follow any such request if the Trustee in good faith shall  determine
that the suit,  proceeding or exercise of the remedy so requested  would involve
the Trustee in personal liability or expense.

                  SECTION 1.027.  Control by Securityholders.

                  The  Holders  of  a  majority  in  principal   amount  of  the
Outstanding Securities shall have the right to direct the time, method and place
of  conducting  any  proceeding  for any  remedy  available  to the  Trustee  or
exercising any trust or power conferred on the Trustee, provided that

                  (1) such  direction  shall not be in conflict with any rule of
         law or with this Indenture, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

                  SECTION 1.028.  Waiver of Past Defaults.

                  The Holders of not less than a majority in principal amount of
the  Outstanding  Securities  may on behalf of the Holders of all the Securities
waive any past  default  hereunder  and its  consequences,  except that only the
Holders of all Securities affected thereby may waive a default

                  (1) in the payment of the principal of (or premium, if any) or
         interest on such Securities,

         or

                  (2) in respect of a covenant or  provision  hereof which under
         Article Eleven cannot be modified or amended without the consent of the
         Holder of each Outstanding Security affected.

                  Upon any such waiver,  such default shall cease to exist,  and
any Event of Default arising  therefrom shall be deemed to have been cured,  for
every  purpose  of  this  Indenture;  but no such  waiver  shall  extend  to any
subsequent or other default or impair any right consequent thereon.

                  SECTION 1.029.  Securityholder May Not Bring Suit Except under
Certain Conditions.

                  A  Securityholder  shall not have the right to  institute  any
suit,  action or proceeding at law or in equity or otherwise for the foreclosure
of this  Indenture,  for the appointment of a receiver or for the enforcement of
any other remedy under or upon this Indenture, unless:

                  (1) such  Securityholder  previously  shall have given written
         notice to the Trustee of a continuing Event of Default;

                  (2) the Holders of at least 25% in aggregate  principal amount
         of the Securities then Outstanding  shall have requested the Trustee in
         writing to institute  such action,  suit or  proceeding  and shall have
         offered to the Trustee indemnity as provided in Section 9.03(e);

                  (3) the Trustee  shall have  refused or neglected to institute
         any such action,  suit or proceeding  for 60 days after receipt of such
         notice, request and offer of indemnity; and

                  (4) no direction  inconsistent  with such written  request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of outstanding Securities.

                  It is  understood  and  intended  that  no one or  more of the
Securityholders  shall have any right in any manner whatever  hereunder or under
the Securities to (i) surrender, impair, waive, affect, disturb or prejudice the
Lien of this  Indenture  on any  property  subject  thereto or the rights of the
Holders  of any other  Securities,  (ii)  obtain or seek to obtain  priority  or
preference  over any other such  Holder or (iii)  enforce  any right  under this
Indenture,  except in the manner herein provided and for the equal,  ratable and
common  benefit of all the  Securityholders  subject to the  provisions  of this
Indenture.

                  SECTION 1.10.  Undertaking To Pay Court Costs.

                  All parties to this Indenture,  and each Securityholder by his
acceptance  of a Security,  shall be deemed to have agreed that any court may in
its discretion require, in any suit, action or proceeding for the enforcement of
any right or remedy under this Indenture,  or in any suit,  action or proceeding
against the Trustee for any action taken or omitted by it as Trustee  hereunder,
the  filing by any party  litigant  in such  suit,  action or  proceeding  of an
undertaking to pay the costs of such suit,  action or proceeding,  and that such
court may, in its discretion,  assess  reasonable  costs,  including  reasonable
attorneys' fees,  against any party litigant in such suit, action or proceeding,
having due regard to the merits and good faith of the claims or defenses made by
such party  litigant;  provided,  however,  that the  provisions of this Section

Securityholders  holding in the aggregate  more than 10% in aggregate  principal
amount of the Securities then Outstanding or (c) any suit,  action or proceeding
instituted  by any  Securityholder  for the  enforcement  of the  payment of the

the right of any Holder of any Security to receive  payment of the principal of,
and premium, if any, and interest on, such Security,  on or after the respective

Redemption  Date  fixed  for  such  Security),  or to  institute  suit  for  the
enforcement of any such payment on or after such respective dates,  shall not be
impaired or affected without the consent of such Holder.

                  SECTION 1.12.  Application of Moneys Collected by Trustee.

                  Any moneys  collected or to be applied by the Trustee pursuant

                  FIRST: to the payment of all taxes, assessments or liens prior
         to the Lien of this  Indenture,  except those subject to which any sale
         shall have been made, all reasonable  costs and expenses of collection,

         such proceeds shall be  insufficient to pay in full the whole amount so
         due and unpaid, then to the payment of such principal, premium, if any,
         and interest ratably, without discrimination or preference; and

                  FIFTH: in case the principal of all the Securities  shall have

                  SECTION 1.14. Waiver of Appraisement,  Valuation,  Stay, Right
to Marshalling.

                  To the  extent  it may  lawfully  do so,  each  of PNM and the
Company,  for  itself  and for any  Person  who may claim  through  or under it,
hereby:

                  (1) agrees  that  neither it nor any such  Person will set up,
         plead,  claim  or in any  manner  whatsoever  take  advantage  of,  any
         appraisement,  valuation,  stay,  extension or redemption  laws, now or
         hereafter  in force in any  jurisdiction,  which may delay,  prevent or
         otherwise  hinder (i) the  performance or enforcement or foreclosure of
         this Indenture,  (ii) the sale of any of the Pledged Property, or (iii)
         the putting of the purchaser or purchasers  thereof into  possession of
         such property immediately after the sale thereof;

                  (2)  waives all benefit or advantage of any such laws;

                  (3)  waives  and  releases  all  rights  to have  the  Pledged
         Property marshalled upon any foreclosure,  sale or other enforcement of
         this Indenture; and

                  (4) consents  and agrees that all the Pledged  Property may at
         any such sale be sold by the Trustee as an entirety.

               SECTION 1.15.Remedies Cumulative; Delay or Omission Not a Waiver.

                  Every remedy  given  hereunder to the Trustee or to any of the
Securityholders  shall not be exclusive  of any other  remedy or  remedies,  and
every such remedy  shall be  cumulative  and in  addition to every other  remedy
given hereunder or now or hereafter given by statute,  law, equity or otherwise.
The Trustee may exercise all or any of the powers,  rights or remedies  given to
it hereunder or which may now or hereafter be given by statute, law or equity or
otherwise,  in its absolute discretion.  No course of dealing between PNM or the
Company and the Trustee or the  Securityholders  or any delay or omission of the
Trustee or of any Securityholder to exercise any right, remedy or power accruing
upon any Event of Default shall impair any such right,  remedy or power or shall
be  construed to be a waiver of any such Event of Default or of any right of the
Trustee or of the Securityholders or acquiescence  therein,  and, subject to the
provisions of Section 8.07, every right,  remedy and power given by this Article
to the Trustee or to the  Securityholders may be exercised from time to time and
as often as may be deemed expedient by the Trustee or by the Securityholders.

                  SECTION 1.001.  Certain Duties and Responsibilities.

                  (a) Except during the continuance of an Event of Default,

                  (1) the  Trustee  undertakes  to perform  such duties and only
         such duties as are  specifically  set forth in this  Indenture,  and no
         implied  covenants  or  obligations  shall be read into this  Indenture
         against the Trustee; and

                  (2) in the  absence of bad faith on its part,  the Trustee may
         conclusively   rely,  as  to  the  truth  of  the  statements  and  the
         correctness of the opinions  expressed  therein,  upon  certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this  Indenture;  but in the case of any such  certificates or opinions
         which  by  any  provisions  hereof  are  specifically  required  to  be
         furnished to the Trustee,  the Trustee shall be under a duty to examine
         the same to determine  whether or not they conform to the  requirements
         of this Indenture.

                  (b)  In  case  an  Event  of  Default  has   occurred  and  is
continuing,  the Trustee shall  exercise such of the rights and powers vested in
it by this  Indenture,  and use the  same  degree  of care  and  skill  in their
exercise,  as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

                  (c) No  provision  of this  Indenture  shall be  construed  to
relieve  the  Trustee  from  liability  for its own  negligent  action,  its own
negligent failure to act, or its own willful misconduct, except that

                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

                  (2) the Trustee  shall not be liable for any error of judgment
         made in good faith by a Responsible  Officer of the Trustee,  unless it
         shall be proved that the  Trustee was  negligent  in  ascertaining  the
         pertinent facts;

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction  of the  Holders of a  majority  in  principal  amount of the
         Outstanding  Securities  relating  to the  time,  method  and  place of
         conducting any proceeding for any remedy  available to the Trustee,  or
         exercising any trust or power  conferred  upon the Trustee,  under this
         Indenture; and

                  (4) no provision of this  Indenture  shall require the Trustee
         to  expend  or risk its own  funds or  otherwise  incur  any  financial
         liability in the performance of any of its duties hereunder,  or in the
         exercise  of any of its rights or powers,  if it shall have  reasonable
         grounds  for  believing  that  repayment  of  such  funds  or  adequate
         indemnity  against such risk or liability is not reasonably  assured to
         it.

                  (d)  Whether  or  not  herein  expressly  so  provided,  every
provision of this  Indenture  relating to the conduct or affecting the liability
of or affording  protection to the Trustee shall be subject to the provisions of
this Section.

                  SECTION 1.002.  Notice of Defaults.

                  In   addition   to  its   obligation   to   give   notice   to
Securityholders  as provided in Section 3.03, as promptly as practicable  after,
and in any event within 90 days after, the occurrence of any default  hereunder,
the Trustee shall  transmit by mail to all  Securityholders,  as their names and
addresses  appear in the Security  Register,  notice of such  default  hereunder
known to the  Trustee,  unless  such  default  shall  have been cured or waived;
provided,  however,  that, except in the case of a default in the payment of the
principal of (or premium,  if any) or interest on any Security or in the payment
of any Sinking Fund  installment,  the Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee or
a trust  committee of directors  and/or  Responsible  Officers of the Trustee in
good faith  determine that the withholding of such notice is in the interests of
the Securityholders;  and provided,  further, that in the case of any default of
the  character  specified in Section  8.01(4) no such notice to  Securityholders
shall be given  until at least 30 days  after the  occurrence  thereof.  For the
purpose of this Section,  the term "default"  means any event which is, or after
notice or lapse of time or both would become, an Event of Default.

                  SECTION 1.003.  Certain Rights of Trustee.

                  Except as otherwise provided in Section 9.01:

refraining from acting in reliance upon any resolution,  certificate, statement,

and any  resolution  of the  Board of  Directors  of PNM or the  Company  may be
sufficiently  evidenced by a Board Resolution of PNM or the Company, as the case
may be;

                  (c)  whenever  in the  administration  of this  Indenture  the
Trustee shall deem it desirable that a matter be proved or established  prior to
taking,  suffering or omitting any action  hereunder,  the Trustee (unless other
evidence be herein specifically  prescribed) may, in the absence of bad faith on
its part, rely upon an Officers' Certificate of PNM or the Company;

                  (d) the  Trustee may  consult  with  counsel and the advice of
such counsel or any Opinion of Counsel shall be full and complete  authorization

of the  rights  or powers  vested  in it by this  Indenture  at the  request  or
direction of any of the Securityholders pursuant to this Indenture,  unless such
Securityholders  shall  have  offered  to the  Trustee  reasonable  security  or
indemnity against the costs, expenses and liabilities which might be incurred by
it in compliance with such request or direction;

                  (f) the Trustee  shall not be bound to make any  investigation
into the facts or  matters  stated in any  resolution,  certificate,  statement,
instrument,  opinion, report, notice, request, direction,  consent, order, bond,
debenture or other paper or document,  but the Trustee,  in its discretion,  may
make such further inquiry or investigation  into such facts or matters as it may
see fit,  and, if the Trustee  shall  determine to make such further  inquiry or
investigation,  it shall be entitled to examine the books,  records and premises
of PNM or the Company, personally or by agent or attorney; and

                  (g) the  Trustee  may  execute  any of the  trusts  or  powers
hereunder  or perform  any duties  hereunder  either  directly  or by or through
agents or attorneys and the Trustee shall not be responsible  for any misconduct
or negligence on the part of any agent or attorney appointed with due care by it
hereunder.

                  SECTION  1.004.  Not  Responsible  for Recitals or Issuance of
Securities.
                  The recitals  contained  herein and in the Securities,  except
the certificates of authentication,  shall not be taken as the statements of the
Trustee,  and the Trustee assumes no responsibility for their  correctness.  The
Trustee  makes no  representations  as to the  validity or  sufficiency  of this
Indenture,  the  Pledged  Property  or the  Securities,  except that the Trustee
hereby  represents  and  warrants  that this  Indenture  has been  executed  and
delivered by one of its officers who is duly  authorized  to execute and deliver
such document on its behalf. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

agent of PNM or the Company, in its individual or any other capacity, may become
the owner or pledgee of Securities  and,  subject to Sections 9.08 and 9.13, may
otherwise deal with PNM and the Company with the same rights it would have if it

Property  may,  until  paid out by the  Trustee  or the  Paying  Agent as herein

                  [(b) At any time and from  time to time  prior to  payment  in
full of any  amounts to be paid by the Trustee  pursuant  to Section  2.15(b) in
respect of any series of  Securities  (or prior to payment in full of any amount
required  to be paid by the  Trustee  in respect  of such  series of  Securities
pursuant to Section  6.07),  if at the time no Event of Default has occurred and
is continuing,  the Trustee shall,  on Company  Request,  invest and reinvest in
Permitted  Investments as specified in such Company  Request any monies from the
sale of the Securities of such series at the time on deposit with the Trustee as
part of the  Pledged  Property,  together  with any  income  and gains  from the
investment and  reinvestment  thereof,  and sell any Permitted  Investments,  in
either case, at such prices,  including  accrued  interest,  as are set forth in
such  Company  Request,  and  such  Permitted  Investments  shall be held by the
Trustee  until so sold in trust as part of the  Pledged  Property.  The  Trustee
shall, on Company Request,  sell such Permitted  Investments as may be specified
therein, and the Trustee shall, without Company Request, in the event monies are
required  for  payment of any  amounts  to be paid by the  Trustee  pursuant  to
Section  2.15(b)  in  respect  of any  series of  Securities  and for any Stated
Maturity of any installment of interest on any series of Securities becoming due
and payable prior to the thirtieth day following the Termination Date applicable
to such series,  sell such  Permitted  Investments as are required to restore to
cash as part of the  Pledged  Property  such  amounts as are needed for any such

         any Authorized Agent from time to time reasonable  compensation for all
         services  rendered by it  hereunder  (which  compensation  shall not be
         limited  by any  provision  of law in regard to the  compensation  of a
         trustee of an express trust);

                  (2) to  reimburse,  or  cause  to be  reimbursed,  each of the
         Trustee and any  Authorized  Agent upon its  request for all  expenses,
         disbursements  and advances  incurred or made by it in accordance  with
         any provision of this  Indenture  (including the  compensation  and the
         expenses and disbursements of its agents and counsel),  except any such
         expense,  disbursement  or  advance as may be  attributable  to its own
         negligence, willful misconduct or bad faith; and

                  (3) to  indemnify,  or  cause to be  indemnified,  each of the
         Trustee,  any predecessor  Trustee and any Authorized Agent for, and to
         hold it  harmless  against,  any loss,  liability  or expense  incurred
         without  negligence,  willful  misconduct  or bad  faith  on its  part,
         arising out of or in connection  with the acceptance or  administration
         of this trust or the performance of its duties hereunder, including the
         costs and expenses of defending  itself  against any claim or liability
         in connection  with the exercise or performance of any of its powers or
         duties hereunder.

                  As security  for the  performance  of the  obligations  of the
Company under this Section the Trustee shall have a lien prior to the Securities
upon all property  and funds held or  collected  by the Trustee as such,  except
funds held in trust for the payment of  principal  of (and  premium,  if any) or
interest on particular Securities


                  SECTION 1.008.  Disqualification; Conflicting Interests.

                  (a) If  the  Trustee  has or  shall  acquire  any  conflicting
interest,   as  defined  in  this  Section,  it  shall,  within  90  days  after
ascertaining  that it has  such  conflicting  interest,  either  eliminate  such
conflicting  interest  or resign in the manner  and with the effect  hereinafter
specified in this Article.

                  (b) In the event that the  Trustee  shall fail to comply  with
the provisions of Subsection  (a) of this Section the Trustee  shall,  within 10
days  after  the  expiration  of such  90-day  period,  transmit  by mail to all
Securityholders,  as their names and addresses appear in the Security  Register,
notice of such failure.

                  (c) For the  purposes of this  Section,  the Trustee  shall be
deemed to have a conflicting interest if

                  (1) the Trustee is trustee under another Indenture under which
         any other  securities,  or certificates of interest or participation in
         any other securities, of any obligor on the Securities are outstanding,
         unless (A) the Securities  are  collateral  trust bonds under which the
         only  Collateral   consists  of  securities  issued  under  such  other
         indenture,  or (B) such other indenture is a collateral trust indenture
         under which the only  collateral  consists of  Securities  issued under
         this  Indenture,  provided  that  there  shall  be  excluded  from  the
         operation of this  paragraph any  indenture or  indentures  under which
         other securities, or certificates of interest or participation in other
         securities, of such obligor are outstanding, if such obligor shall have
         sustained the burden of proving,  on  application to the Commission and
         after  opportunity for hearing  thereon,  that  trusteeship  under this
         Indenture  and such other  indenture or  indentures is not so likely to
         involve a material  conflict of interest as to make it necessary in the
         public  interest or for the  protection of investors to disqualify  the
         Trustee from acting as such under one of such indentures;

                  (2) the Trustee or any of its directors or executive  officers
         is an obligor upon the Securities or an underwriter for such obligor;

                  (3) the Trustee directly or indirectly controls or is directly
         or  indirectly  controlled  by or is under  direct or  indirect  common
         control with any obligor on the Securities or an  underwriter  for such
         obligor;

                  (4) the Trustee or any of its directors or executive  officers
         is a director, officer, partner, employee,  appointee or representative
         of any obligor on the Securities,  or of an underwriter (other than the
         Trustee  itself)  for such  obligor  who is  currently  engaged  in the
         business  of  underwriting,  except  that (i) one  individual  may be a
         director  or an  executive  officer,  or  both,  of the  Trustee  and a
         director  or an  executive  officer,  or  both,  of an  obligor  on the
         Securities but may not be at the same time an executive officer of both
         the  Trustee  and such  obligor;  (ii) if and so long as the  number of
         directors  of the Trustee in office is more than nine,  one  additional
         individual  may be director or an executive  officer,  or both,  of the
         Trustee and a director of an obligor on the  Securities;  and (iii) the
         Trustee may be  designated  by an obligor on the  Securities  or by any
         underwriter  for such obligor to act in the capacity of transfer agent,
         registrar,  custodian,  paying agent,  fiscal agent,  escrow agent,  or
         depositary,  or in any  other  similar  capacity,  or,  subject  to the
         provisions  of  paragraph  (1) of this  Subsection,  to act as trustee,
         whether under an indenture or otherwise;

                  (5) 10% or more of the  voting  securities  of the  Trustee is
         beneficially  owned  either  by any  director,  partner,  or  executive
         officer  thereof,   or  20%  or  more  of  such  voting  securities  is
         beneficially owned,  collectively,  by any two or more of such persons;
         or 10% or more of the voting  securities of the Trustee is beneficially
         owned either by an underwriter  for any obligor on the Securities or by
         any director,  partner or executive officer thereof, or is beneficially
         owned collectively by any two or more such persons;

                  (6) the  Trustee  is the  beneficial  owner  of,  or  holds as
         collateral   security  for  an  obligation  which  is  in  default  (as
         hereinafter in this Subsection  defined),  (i) 5% or more of the voting
         securities,  or 10% or more of any  other  class  of  security,  of any
         obligor on the  Securities  not including the  Securities  issued under
         this Indenture and securities  issued under any other  indenture  under
         which the Trustee is also trustee,  or (ii) 10% or more of any class of
         security of an underwriter for any obligor on the Securities;

<PAGE>

                  (7) the  Trustee  is the  beneficial  owner  of,  or  holds as
         collateral   security  for  an  obligation  which  is  in  default  (as
         hereinafter  in this  Subsection  defined),  5% or  more of the  voting
         securities of any person who, to the knowledge of the Trustee, owns 10%
         or more of the voting securities of, or controls directly or indirectly
         or is under direct or indirect  common control with, any obligor on the
         Securities;

                  (8)  the  Trustee  is  the  beneficial   owner  of,  or  holds
         collateral   security  for  an  obligation  which  is  in  default  (as
         hereinafter in this  Subsection  defined),  10% or more of any class of
         security of any person who, to the  knowledge of the Trustee,  owns 50%
         or more of the voting securities of any obligor on the Securities; or

                  (9) the Trustee owns,  on May 15 in any calendar  year, in the
         capacity  of  executor,  administrator,  testamentary  or  inter  vivos
         trustee,  guardian,  committee or conservator,  or in any other similar
         capacity,  an aggregate of 25% or more of the voting securities,  or of
         any class of security,  of any person,  the  beneficial  ownership of a
         specified  percentage  of which would have  constituted  a  conflicting
         interest under paragraphs (6), (7) or (8) of this Subsection. As to any
         such  securities  of  which  the  Trustee  acquired  ownership  through
         becoming executor,  administrator, or testamentary trustee of an estate
         which included them, the provisions of the preceding sentence shall not
         apply,  for a period of two years from the date of such  acquisition to
         the extent that such  securities  included in such estate do not exceed
         25% of such  voting  securities  or 25% of any such class of  security.
         Promptly  after May 15 in each calendar  year, the Trustee shall make a
         check of its holdings of such  securities in any of the above mentioned
         capacities as of such May 15. If any obligor upon the Securities  fails
         to make payment in full of the principal of, or the premium, if any, or
         interest on, any of the Securities when and as the same becomes due and
         payable, and such failure continues for 30 days thereafter, the Trustee
         shall make a prompt check of its holdings of such  securities in any of
         the above mentioned capacities as of the date of the expiration of such
         30 day  period,  and after such  date,  notwithstanding  the  foregoing
         provisions  of  this  paragraph,  all  such  securities  so held by the
         Trustee,  with sole or joint control over such securities vested in it,
         shall,  but only so long as such failure shall continue,  be considered
         as  though  beneficially  owned  by the  Trustee  for the  purposes  of
         paragraphs (6), (7) and (8) of this Subsection.

                  The  specification  of  percentages  in paragraphs  (5) to (9)
inclusive,  of this  Subsection,  shall not be construed as indicating  that the
ownership  of  such  percentages  of the  securities  of a  person  is or is not
necessary  or  sufficient  to  constitute  direct or  indirect  control  for the
purposes of paragraph (3) or (7) of this Subsection.

                  For the purposes of  paragraphs  (6), (7), (8) and (9) of this
Subsection only, (i) the terms  "security" and  "securities"  shall include only
such  securities as are generally known as corporate  securities,  but shall not
include  any note or other  evidence  of  indebtedness  issued  to  evidence  an
obligation  to repay  moneys  loaned  to a person  by one or more  banks,  trust
companies or banking firms, or any certificate of interest or  participation  in
any such note or evidence or indebtedness; (ii) an obligation shall be deemed to
be "in default" when a default in payment of principal  shall have continued for
30 days or more and shall not have been cured;  and (iii) the Trustee  shall not
be  deemed  to be the  owner or  holder  of (A) any  security  which it holds as
collateral security, as trustee or otherwise,  for an obligation which is not in
default as defined in clause (ii) above,  or (B) any security  which it holds as
collateral security under this Indenture, irrespective of any default hereunder,
or (C) any security  which it holds as agent for  collection,  or as  custodian,
escrow agent, or depositary, or in any similar representative capacity.

                  Except as provided in the next preceding  paragraph,  the word
"security" or "securities" as used in this Indenture shall mean any note, stock,
treasury  stock,  bond,  debenture,  evidence of  indebtedness,  certificate  of
interest or  participation  in any profit sharing  agreement,  collateral  trust
certificate,  preorganization  certificate or subscription,  transferable share,
investment  contract,  voting trust  certificate,  certificate  of deposit for a
security,  fractional  undivided  interest in oil, gas, or other mineral rights,
or, in general,  any interest or instrument  commonly known as a "security",  or
any  certificate  of  interest  or   participation   in,  temporary  or  interim
certificate for,  receipt for,  guarantee of, or warrantor right to subscribe to
purchase, any of the foregoing.

         obligor on the  Securities  means every person who,  within three years
         prior to the time as of which the  determination is made, has purchased
         from  such  obligor  with a view to,  or has  offered  or sold for such
         obligor in connection  with, the  distribution  of any security of such
         obligor  outstanding  at such time,  or has  participated  or has had a
         direct  or  indirect  participation  in any  such  undertaking,  or has
         participated  or has had a  participation  in the  direct  or  indirect
         underwriting of any such undertaking, but such term shall not include a
         person whose  interest was limited to a commission  from an underwriter
         or dealer  not in excess of the usual and  customary  distributors'  or
         sellers' commission.

         thereof. As used in this paragraph, the term "trust" shall include only
         a  trust  where  the  interest  or  interests  of  the  beneficiary  or
         beneficiaries are evidenced by a security.

                  (4) The term "voting  security"  means any security  presently
         entitling  the  owner or holder  thereof  to vote in the  direction  or
         management of the affairs of a person,  or any security issued under or
         pursuant to any trust,  agreement or  arrangement  whereby a trustee or
         trustees  or agent or agents  for the owner or holder of such  security
         are  presently  entitled to vote in the  direction or management of the

                  (4) The term "outstanding" means issued and not held by or for
         the account of the issuer. The following securities shall not be deemed
         outstanding within the meaning of this definition:

                           (i)  securities  of an issuer held in a sinking  fund
                  relating to securities of the issuer of the same class;

                           (ii)  securities  of an issuer held in a sinking fund
                  relating to another class of securities of the issuer,  if the
                  obligation  evidenced by such other class of securities is not
                  in default as to principal or interest or otherwise;

                           (iii)  securities  pledged by the  issuer  thereof as
                  security for an  obligation of the issuer not in default as to

                           (iv) securities held in escrow if placed in escrow by
                  the issuer thereof;

provided,  however,  that any  voting  securities  of an issuer  shall be deemed
outstanding  if any person  other than the issuer is entitled  to  exercise  the
voting rights thereof.

                  (5) A  security  shall be  deemed  to be of the same  class as
         another  security if both securities  confer upon the holder or holders
         substantially the same rights and privileges;  provided,  however, that
         in the case of  secured  evidences  of  indebtedness,  all of which are
         issued under a single  indenture,  differences in the interest rates or
         maturity dates of various series thereof shall not be deemed sufficient
         to constitute such series  different  classes;  and provided,  further,
         that, in the case of unsecured  evidences of indebtedness,  differences
         in the interest  rates or maturity  dates  thereof  shall not be deemed
         sufficient to constitute them securities of different classes,  whether
         or not they are issued under a single indenture.

                  SECTION 1.009.  Corporate Trustee Required; Eligibility.

                  There shall at all times be a Trustee hereunder which shall be
a corporation  organized and doing  business under the laws of the United States
of America or of any State,  authorized  under such laws to  exercise  corporate
trust powers, having a combined capital and surplus of at least $50,000,000, and
subject to supervision or  examination  by Federal or State  authority.  If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid  supervising or examining  authority,  then
for the  purposes  of this  Section,  the  combined  capital and surplus of such
corporation  shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

                  SECTION  1.10.   Resignation   and  Removal;   Appointment  of
Successor.

                  (a)  No   resignation   or  removal  of  the  Trustee  and  no
appointment  of a  successor  Trustee  pursuant  to this  Article  shall  become
effective  until the acceptance of  appointment  by the successor  Trustee under
Section 9.11.

                  (b) The  Trustee  may  resign  at any time by  giving  written
notice  thereof to PNM and the Company.  If an  instrument  of  acceptance  by a
successor  Trustee  shall not have been  delivered  to PNM,  the Company and the
Trustee  within 30 days  after the  giving of such  notice of  resignation,  the
resigning  Trustee may  petition  any court of  competent  jurisdiction  for the
appointment of a successor Trustee.

                  (c)  The  Trustee  may be  removed  at any  time by Act of the
Holders  of a  majority  in  principal  amount  of the  Outstanding  Securities,
delivered to the Trustee, PNM and to the Company.

                  (d)  If at any time:

                           (i) the  Trustee  shall fail to comply  with  Section
                  9.08(a) after written request therefor by any Lessor or by any
                  Securityholder  who has been a bona fide  Holder of a Security
                  for at least 6 months, or

                           (ii) the Trustee  shall  cease to be  eligible  under
                  Section  9.09 and shall fail to resign after  written  request
                  therefor by any Lessor or by any such Securityholder, or

                           (iii) the Trustee shall become incapable of acting or
                  shall be adjudged a bankrupt or insolvent or a receiver of the
                  Trustee or of its  property  shall be  appointed or any public
                  officer  shall take charge or control of the Trustee or of its
                  property  or  affairs  for  the  purpose  of   rehabilitation,
                  conservation or liquidation,

then, in any such case, (i) PNM, acting after consultation with the Company, may
remove the Trustee by Board  Resolution  or (ii)  subject to Section  8.10,  any
Securityholder  who has been a bona  fide  Holder of a  Security  for at least 6
months may, on behalf of himself and all others similarly situated, petition any
court  of  competent  jurisdiction  for  the  removal  of the  Trustee  and  the
appointment of a successor Trustee.

                  (e)  If  the  Trustee  shall  resign,  be  removed  or  become
incapable  of acting,  or if a vacancy  shall occur in the office of Trustee for
any cause,  PNM,  acting after  consultation  with the Company,  shall  promptly
appoint by Board  Resolution a successor  Trustee.  If, within 1 year after such
resignation,  removal or  incapability,  or the  occurrence of such  vacancy,  a
successor  Trustee  shall be  appointed  by Act of the  Holders of a majority in
principal amount of the Outstanding Securities delivered to PNM, the Company and
the retiring Trustee,  the successor Trustee so appointed shall,  forthwith upon
its acceptance of such  appointment,  become the successor Trustee and supersede
the successor  Trustee appointed by PNM. If no successor Trustee shall have been
so  appointed  by PNM,  acting after  consultation  with the Company,  or by the
Securityholders,  and accepted  appointment in the manner hereinafter  provided,
any  Securityholder who has been a bona fide Holder of a Security for at least 6
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee and each  appointment  of a successor  Trustee by mailing
written  notice of such  event by  first-class  mail,  postage  prepaid,  to the
Holders  of  Securities  as their  names and  addresses  appear in the  Security
Register.  Each notice shall include the name of the  successor  Trustee and the
address of its Corporate Trust Office.

                  SECTION 1.11.  Acceptance of Appointment by Successor.

                  Every  successor  Trustee  appointed  hereunder shall execute,
acknowledge  and  deliver to PNM,  the Company  and to the  retiring  Trustee an
instrument accepting such appointment,  and thereupon the resignation or removal
of the retiring  Trustee  shall become  effective  and such  successor  Trustee,
without any further act,  deed or  conveyance,  shall become vested with all the
rights,  powers,  trusts and duties of the retiring Trustee;  but, on request of
any Lessor, the Company or the successor  Trustee,  such retiring Trustee shall,
upon payment of its charges,  execute and deliver an instrument  transferring to
such  successor  Trustee  all the  rights,  powers  and  trusts of the  retiring
Trustee,  and shall duly assign,  transfer and deliver to such successor Trustee
all  property  and  money  held  by such  retiring  Trustee  hereunder,  subject
nevertheless to its lien, if any,  provided for in Section 9.07. Upon request of
any such  successor  Trustee,  PNM and the  Company  shall  execute  any and all
instruments  for more  fully and  certainly  vesting in and  confirming  to such
successor Trustee all such rights, powers and trusts.

                  No successor  Trustee shall accept its  appointment  unless at
the time of such  acceptance  such  successor  Trustee  shall be  qualified  and
eligible under this Article.

                  SECTION 1.12. Merger, Conversion,  Consolidation or Succession
to Business.

                  Any  corporation  into  which  the  Trustee  may be  merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion  or  consolidation  to which the Trustee shall be a
party,  or  any  corporation  succeeding  to  all  or  substantially  all of the
corporate  trust business of the Trustee,  shall be the successor of the Trustee
hereunder,  provided such corporation shall be otherwise  qualified and eligible
under this Article,  without the execution or filing of any paper or any further
act on the part of any of the parties hereto.  In case any Securities shall have
been  authenticated,  but not  delivered,  by the  Trustee  then in office,  any
successor by merger,  conversion or consolidation to such authenticating Trustee
may adopt such  authentication  and deliver the Securities so authenticated with
the same  effect as if such  successor  Trustee  had itself  authenticated  such
Securities.

                  SECTION 1.13.  Preferential  Collection of Claims  against any
Obligor.

                   [(a)  Subject  to  Subsection  (b) of  this  Section,  if the
Trustee shall be or shall become a creditor, directly or indirectly,  secured or
unsecured,  of any obligor on the  Securities  (as defined in Subsection  (c) of
this Section)  within 4 months prior to a default,  as defined in Subsection (c)
of this Section,  or subsequent to such a default,  then,  unless and until such
default  shall be  cured,  the  Trustee  shall  set  apart and hold in a special
account  for  the  benefit  of the  Trustee  individually,  the  Holders  of the
Securities  and the  holders  of  other  indenture  securities  (as  defined  in
Subsection (c) of this Section):

                           (i) an amount equal to any and all  reductions in the
                  amount  due and  owing  upon  any  claim as such  creditor  in
                  respect of principal or interest, effected after the beginning
                  of such 4 month period and valid as against any obligor on the
                  Securities and its other creditors,  except any such reduction
                  resulting  from the  receipt or  disposition  of any  property
                  described in paragraph  (ii) of this  Subsection,  or from the
                  exercise of any right of set-off  which the Trustee could have
                  exercised  if a petition  in  bankruptcy  had been filed by or
                  against any such obligor upon the date of such default; and

                           (ii) all property  received by the Trustee in respect
                  of any claim as such creditor, either as security therefor, or
                  in satisfaction or composition  thereof,  or otherwise,  after
                  the  beginning of such 4 month  period,  or an amount equal to
                  the proceeds of any such  property,  if disposed of,  subject,
                  however,  to  the  rights,  if  any,  of  any  obligor  on the
                  Securities  and its other  creditors in such  property or such
                  proceeds.

Nothing herein contained, however, shall affect the right of the Trustee

                           (A) to retain for its own account (i)  payments  made
                  on  account of any such  claim by any  Person  (other  than an
                  obligor on the Securities) who is liable thereon, and (ii) the
                  proceeds  of the  bona  fide  sale of any  such  claim  by the
                  Trustee to a third  person,  and (iii)  distributions  made in
                  cash,  securities or other property in respect of claims filed
                  against  such  obligor in  bankruptcy  or  receivership  or in
                  proceedings  for   reorganization   pursuant  to  the  Federal
                  Bankruptcy Act or applicable State law;

                           (B)  to  realize,  for  its  own  account,  upon  any
                  property  held by it as security  for any such claim,  if such
                  property  was so held prior to the  beginning  of such 4 month
                  period;

                           (C) to realize,  for its own account, but only to the
                  extent of the claim hereinafter  mentioned,  upon any property
                  held by it as security  for any such claim,  if such claim was
                  created  after the  beginning  of such 4 month period and such
                  property was received as security therefor simultaneously with
                  the creation thereof,

#30122041.1
                                       45

                  and if the Trustee shall sustain the burden of proving that at
                  the time such  property  was so  received  the  Trustee had no
                  reasonable  cause to  believe  that a default  as  defined  in
                  Subsection (c) of this Section would occur within 4 months; or

                           (D) to receive  payment on any claim  referred  to in
                  paragraph (B) or (C), against the release of any property held
                  as security  for such claim as provided  in  paragraph  (B) or
                  (C),  as the case may be, to the  extent of the fair  value of
                  such property.

For the purposes of paragraphs (B), (C) and (D), property  substituted after the
beginning of such 4 month  period for  property  held as security at the time of
such  substitution  shall,  to the  extent  of the fair  value  of the  property
released, have the same status as the property released, and, to the extent that
any claim  referred to in any of such  paragraphs is created in renewal of or in
substitution  for or for the purpose of repaying or refunding  any  pre-existing
claim of the Trustee as such creditor,  such claim shall have the same status as
such pre-existing claim.

                  If the Trustee  shall be  required  to account,  the funds and
property  held  in such  special  account  and the  proceeds  thereof  shall  be
apportioned  between the Trustee,  the  Securityholders and the holders of other
indenture  securities in such manner that the Trustee,  the  Securityholders and
the holders of other indenture  securities realize, as a result of payments from
such special  account and  payments of  dividends  on claims  filed  against the
obligor on the Securities in bankruptcy or  receivership  or in proceedings  for
reorganization  pursuant to the Federal  Bankruptcy Act or applicable State law,
the same percentage of their respective claims,  figured before crediting to the
claim of the Trustee  anything on account of the receipt by it from such obligor
of the funds and  property in such special  account and before  crediting to the
respective  claims of the  Trustee  and the  Securityholders  and the holders of
other  indenture  securities  dividends on claims filed  against such obligor in
bankruptcy or receivership or in proceedings for reorganization  pursuant to the
Federal  Bankruptcy  Act or applicable  State law, but after  crediting  thereon
receipts on account of the indebtedness  represented by their respective  claims
from all sources other than from such  dividends and from the funds and property
so held in such special account. As used in this paragraph,  with respect to any
claim, the term "dividends"  shall include any distribution with respect to such
claim, in bankruptcy or receivership or proceedings for reorganization  pursuant
to the Federal Bankruptcy Act or applicable State law, whether such distribution
is made in cash,  securities,  or other property, but shall not include any such
distribution  with respect to the secured  portion,  if any, of such claim.  The
court in which such bankruptcy,  receivership or proceedings for  reorganization
is pending shall have  jurisdiction (i) to apportion between the Trustee and the
Securityholders  and the holders of other  indenture  securities,  in accordance
with the  provisions  of this  paragraph,  the funds and  property  held in such
special account and proceeds thereof, or (ii) in lieu of such apportionment,  in
whole or in part, to give to the provisions of this paragraph due  consideration
in determining the fairness of the  distributions  to be made to the Trustee and
the Securityholders  and the holders of other indenture  securities with respect
to their  respective  claims,  in  which  event it  shall  not be  necessary  to
liquidate or to appraise the value of any  securities or other  property held in
such special  account or as security  for any such claim,  or to make a specific
allocation of such  distributions as between the secured and unsecured  portions
of such  claims,  or otherwise to apply the  provisions  of this  paragraph as a
mathematical formula.

                  Any  Trustee  which has  resigned  or been  removed  after the
beginning  of such 4 month  period  shall be subject to the  provisions  of this
Subsection  as though  such  resignation  or removal  had not  occurred.  If any
Trustee has  resigned or been  removed  prior to the  beginning  of such 4 month
period,  it shall be subject to the provisions of this Subsection if and only if
the following conditions exist:

                  (i) the receipt of property or reduction of claim, which would
         have  given rise to the  obligation  to  account  if such  Trustee  had
         continued  as Trustee,  occurred  after the  beginning  of such 4 month
         period; and

                  (ii) such receipt of property or  reduction of claim  occurred
         within 4 months after such resignation or removal.

                  (b) There shall be excluded  from the  operation of Subsection
         (a) of this Section a creditor relationship arising from

                  (1) the ownership or  acquisition  of securities  issued under
         any indenture,  or any security or securities  having a maturity of one
         year or more at the time of acquisition by the Trustee;

                  (2) advances  authorized by a receivership or bankruptcy court
         of competent  jurisdiction,  or by this  Indenture,  for the purpose of
         preserving  any property which shall at any time be subject to the lien
         of this Indenture or of  discharging  tax liens or other prior liens or
         encumbrances   thereon,   if  notice  of  such   advances  and  of  the
         circumstances   surrounding   the  making   thereof  is  given  to  the
         Securityholders  at the  time  and  in  the  manner  provided  in  this
         Indenture;

                  (3)  disbursements  made in the ordinary course of business in
         the capacity of trustee under an indenture,  transfer agent, registrar,
         custodian,  paying agent, fiscal agent or depositary,  or other similar
         capacity;

                  (4) an indebtedness  created as a result of services  rendered
         or premises rented; or an indebtedness  created as a result of goods or
         securities  sold in a cash  transaction as defined in Subsection (c) of
         this Section;

                  (5)  the  ownership  of  stock  or of  other  securities  of a
         corporation  organized  under the  provisions  of Section  25(a) of the

15 days prior to the time such list is  furnished;  provided,  however,  that so
long as the  Trustee  is the  sole  Security  Registrar,  no such  list  need be

Securityholders.

referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee  reasonable  proof that each such  applicant  has owned a Security for a
period of at least six months preceding the date of such  application,  and such
application  states that the applicants desire to communicate with other Holders
of  Securities  with respect to their  rights under this  Indenture or under the
Securities  and is  accompanied  by a  copy  of  the  form  of  proxy  or  other
communication which such applicants propose to transmit, then the Trustee shall,
within 5 Business Days after the receipt of such  application,  at its election,
either:

                           (i) afford such applicants  access to the information
                  preserved  at the  time  by the  Trustee  in  accordance  with
                  Section 10.02(a), or

                           (ii) inform  such  applicants  as to the  approximate

                  appear in the information preserved at the time by the Trustee
                  in accordance with Section 10.02(a), and as to the approximate
                  cost of mailing to such  Securityholders  the form of proxy or
                  other communication, if any, specified in such application.

                  If the Trustee shall elect to afford such applicants access to
such  information,   the  Trustee  shall,  upon  the  written  request  of  such
applicants,  mail to each  Securityholder  whose name and address  appear in the
information  preserved  at the time by the Trustee in  accordance  with  Section
10.02(a),  a copy of the form of proxy or other communication which is specified
in such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of  payment,  or  provision  for the  payment,  of the
reasonable  expenses of mailing,  unless within five days after such tender, the
Trustee shall mail to such  applicants  and file with the  Commission,  together
with a copy of the  material  to be mailed,  a written  statement  to the effect
that, in the opinion of the Trustee,  such mailing would be contrary to the best
interests of the Holders of  Securities  or would be in violation of  applicable
law. Such written statement shall specify the basis of such opinions.

in the written statement so filed,  shall enter an order refusing to sustain any
of such objections or if, after the entry of an order  sustaining one or more of
such  objections,  the Commission  shall find,  after notice and opportunity for
hearing,  that all the  objections so sustained have been met and shall enter an
order so  declaring,  the Trustee shall mail copies of such material to all such
Securityholders with reasonable promptness after the entry of such order and the

held  accountable by reason of the disclosure of any such  information as to the
names and  addresses of the Holders of  Securities  in  accordance  with Section

                  (b) Selection of Bonds.  The provisions of Section 7.02 of the
Original  Indenture to the  contrary  notwithstanding,  the Trustee  shall first
select for  redemption  on any Sinking  Fund Date on which Bonds of a particular
Stated  Maturity  of  principal  (other  than  Bonds with a Stated  Maturity  of
principal  of July 15, 1991) are to be redeemed in  accordance  with the Sinking
Fund relating thereto,  such Bonds, if any, of such Stated Maturity of principal
as the Company shall specify (by Bond number) are held by PNM or an Affiliate of
PNM in a Company Request delivered to the Trustee at least 40 (but not more than
90) days prior to such Sinking Fund Date and upon which the Trustee may rely.

                  (c) Certain Adjustments to Sinking Funds. The principal amount
of Bonds of a particular  Stated  Maturity of  principal to be redeemed  through
operation of the Sinking Fund for the Bonds of such Stated Maturity of principal
may be adjusted  (upward or  downward) at the  discretion  of the Company at one
time  (contemporaneously  with similar  adjustments for all Stated Maturities of
principal) prior to July 15, 1988; provided, however, that no such adjustment

#30122043.1
                                       iv

<PAGE>

shall be made by the Company  which will  increase or reduce the average life of
the Bonds of such Stated  Maturity of principal  (calculated in accordance  with
generally accepted financial practice from the date of initial issuance) by more
than 6 months;  provided further,  however,  such adjustment may only be made in
connection  with an  adjustment to basic rent pursuant to Section 3(d) of one or
more of the Leases  identified in Schedule 2 hereto.  If the Company shall elect
to make the foregoing  adjustment,  the Company shall deliver to the Trustee and
PNM at least  60 days  prior to the  first  Sinking  Fund  Date  proposed  to be
affected by such adjustment,  a Company Request (w) stating that the Company has
elected to make such  adjustment in connection  with  adjustments  to basic rent
under  one or more of such  Leases,  (x)  setting  forth a revised  schedule  of
principal amounts of the Sinking Fund applicable to Bonds of the affected Stated
Maturity  of  principal,  (y)  attaching  a copy  of the  revised  schedules  of
principal  amortization  for the related  Pledged  Lessor  Notes  identified  in
Schedule 2 hereto and (z)  attaching  calculations  showing that (i) the average
life of the Bonds of the  affected  Stated  Maturity  of  principal  will not be
reduced  or  increased  except as  permitted  by this  paragraph  (c),  (ii) the
aggregate  principal amount of the Pledged Lessor Notes identified on Schedule 2
hereto  equals  the  aggregate  principal  amount  of the  Bonds  and  (iii) the
aggregate  amortization of the principal  amount of such Pledged Lessor Notes is
sufficient to repay in full, as and when due, the principal  amount of the Bonds
as and when due,  whether upon  redemption  through  operation of the applicable
Sinking Funds or at maturity.  The Trustee may rely on such Company  Request and
shall have no duty with respect to the calculations referred to in the foregoing
clause (z),  other than to make them  available for  inspection by any Holder of
Bonds at the Corporate Trust Office upon reasonable  notice.  The Trustee shall,
at the  expense  of PNM,  send to each  Holder of Bonds of the  affected  Stated
Maturity of principal at least 20 days before the first  Sinking Fund Date to be
affected  thereby,  by first  class  mail,  a copy of such  revised  schedule of
principal amounts of Sinking Fund payments applicable to such Bonds.

                  (d) Redemption  Price. The Redemption Price for any Bond to be
redeemed  pursuant to  paragraph  (a) of this  Section 1.04 shall be 100% of the
principal amount thereof, together with accrued interest to the Redemption Date.

                                   ARTICLE IV.

                  FIRST  PV  FUNDING   CORPORATION,   a   Delaware   corporation
(hereinafter called the "Company", which term includes any successor corporation
under the  Indenture  referred to on the reverse  hereof),  for value  received,
hereby  promises  to pay to the  Registered  Holder  (named  above)  hereof,  or
registered  assigns,  the Principal Amount (stated above) on the Stated Maturity
(stated  above) and to pay interest  thereon  from the date hereof,  or from the
most  recent  interest  payment  date to which  interest  has been  paid or duly
provided for,  semiannually on July 15 and January 15, in each year,  commencing
January 15, 1987,  at the  Interest  Rate  (stated  above) per annum,  until the
principal hereof is paid in full or made available for payment.  The interest so
payable,  and punctually paid or duly provided for, on any interest payment date
will,  as provided in such  Indenture,  be paid to the person in whose name this
Bond (or one or more  Predecessor  Securities,  as defined in such Indenture) is
registered  at the  close  of  business  on the  Regular  Record  Date  for such
interest, which shall be the June 30 or December 31, as the case may be (whether
or not a Business  Day,  as  defined in such  Indenture),  next  preceding  such
interest payment date. Any such interest not so punctually paid or duly provided
for shall forthwith cease to be payable to the Registered Holder on such Regular
Record  Date,  and may be paid to the  person in whose name this Bond (or one or
more Predecessor Securities) is registered at the close of business on a Special
Record  Date  for the  payment  of such  defaulted  interest  to be fixed by the
Trustee, notice of which shall be given to the Bondholders not less than 10 days
prior to such  Special  Record  Date,  or may be paid at any  time in any  other
lawful manner not inconsistent with the requirements of any securities  exchange
on which the Bonds may be listed,  and upon such  notice as may be  required  by
such  exchange,  all as more fully  provided in such  Indenture.  Payment of the
principal of (and premium, if any) and interest on this Bond will be made at the
corporate trust office of the Paying Agent,  Chemical Bank (or if such office is
not in the Borough of Manhattan,  The City of New York, at either such office or
an office to be  maintained  in such  Borough),  in such coin or currency of the
United  States of America as at the time of payment is legal  tender for payment
of interest  or may be made at the option of the Company by check  mailed to the
address  of the Holder  entitled  thereto as such  address  shall  appear on the
Security Register.

                  Interest on any overdue principal and premium, if any, and (to
the extent  permitted by applicable law) any overdue  interest shall be paid, on
demand, from the due date thereof at the rate of interest per annum (computed on
the  basis of a  360-day  year of twelve  30-day  months)  equal to 1% above the
Interest  Rate (stated  above) on this Bond for the period during which any such
principal, premium or interest shall be overdue.

                            [FORM OF REVERSE OF BOND]

                          FIRST PV FUNDING CORPORATION

                       LEASE OBLIGATION BOND SERIES 1986A

                  This Bond is one of an  authorized  issue of Securities of the
Company known as its "Lease  Obligation Bonds Series 1986A" (the "Bonds") issued
under,  and all equally and ratably  secured by, a  Collateral  Trust  Indenture
dated as of December 16, 1985 among the Company,  Public Service  Company of New
Mexico, a New Mexico  corporation  (herein called "PNM"),  and Chemical Bank, as
Trustee (herein called the "Trustee",  which term includes any successor Trustee
under the Indenture), as heretofore supplemented and as further supplemented and
amended by the Series  1986A Bond  Supplemental  Indenture  dated as of July 15,
1986 among such  parties  (collectively,  the  "Indenture")  to which  Indenture
reference  is hereby  made for a  description  of the  nature  and extent of the
securities and other property assigned,  pledged and transferred thereunder, the
respective rights of the holders of the Bonds and of the Trustee and the Company
in respect of such  security,  and the terms upon which the Bonds are and are to
be authenticated and delivered.

                  The principal  of, and premium,  if any, and interest on, this
Bond are payable  from,  and  secured by, the assets  subject to the lien of the
Indenture or the income and proceeds received by the Trustee therefrom,  and all
payments of principal, premium (if any) and interest shall be made in accordance
with the terms of the Indenture.

                  The Indenture and each of the  Participation  Agreements among
an Equity Investor (as hereinafter  defined), a Lessor (as hereinafter defined),
the Company,  the Lease Indenture  Trustee (as hereinafter  defined) and certain
other  parties  (each a  "Participation  Agreement")  provide  that, as and when
issued,  certain  Nonrecourse  Promissory Notes (the "Pledged Lessor Notes"), in
aggregate  principal amount of $253,677,000,  to be issued by The First National
Bank of Boston,  as owner trustee under one or more separate  Trust  Agreements,
with the respective  institutional investors named in such Trust Agreements (The
First National Bank of Boston in each of such  capacities as owner trustee being
herein  called a "Lessor"  and each such  institutional  investor  being  herein
called an "Equity Investor"),  will be included within the assets subject to the
lien of the Indenture  pursuant to indenture  supplements.  Such Pledged  Lessor
Notes  are to be issued  under  separate  documents  entitled  Trust  Indenture,
Mortgage,  Security Agreement and Assignment of Rents, each between a Lessor and
Chemical Bank, as trustee (the "Lease  Indenture  Trustee")  (each of such Trust
Indentures,  as it is  executed  and  delivered  and as  thereafter  amended  in
accordance with its terms, being herein called a "Lease  Indenture").  Reference
is made to each Lease  Indenture for a  description  of the nature and extent of
property to be assigned,  pledged,  transferred and mortgaged thereunder and the
rights of the holders of notes issued  thereunder,  including the Pledged Lessor
Notes.  Except as  expressly  provided  in a Lease  Indenture,  all  payments of
principal, premium, if any, and interest to be made on a Pledged Lessor Note and
under such Lease Indenture will be made only from the assets subject to the lien
of such  Lease  Indenture  or the  income  and  proceeds  received  by the Lease
Indenture Trustee therefrom, including, in the case of each Lease Indenture, the
rights of the  Lessor  which is a party  thereto to receive  basic  rentals  and
certain other payments under a Lease with PNM relating to an undivided  interest
in certain assets constituting part of the Palo Verde Nuclear Generating Station
(also known as the Arizona Nuclear Power Project) (each of such Leases, as it is
executed and  delivered and as to be hereafter  amended in  accordance  with its
terms being herein  called a "Lease"),  which basic  rentals and other  payments
will be at least  sufficient  to provide for the payment of the principal of and
premium,  if any,  and  interest on each  Pledged  Lessor Note issued under such
Lease Indenture.  Each Holder hereof, by its acceptance of this Bond, agrees (x)
that  except as  expressly  provided  above,  it will look  solely to the assets
subject to the lien of the Indenture or the income and proceeds  received by the
Trustee therefrom, to the extent available for distribution to the Holder hereof
as provided in the Indenture and (y) that none of an Equity Investor,  a Lessor,
a Lease  Indenture  Trustee or the Trustee is liable to the Holder hereof or, in
the case of an Equity Investor,  a Lessor and a Lease Indenture Trustee,  to the
Trustee for any amounts  payable  under this Bond or,  except as provided in the
Indenture with respect to the Trustee, for any liability under the Indenture. An
Equity Investor shall not have any duty or responsibility under the Indenture or
the Bonds to any Holder or to the Trustee.

                  The  Indenture  permits,  with certain  exceptions  as therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of PNM and  the  Company  and  the  rights  of the  Holders  of the
Securities  under  the  Indenture  at any time by PNM and the  Company  with the
consent of the Holders of not less than a majority in aggregate principal amount

of the  Securities at the time  Outstanding,  as defined in the  Indenture.  The
Indenture  also  contains   provisions   permitting  the  Holders  of  specified
percentages  in  aggregate  principal  amount  of the  Securities  at  the  time
Outstanding, on behalf of the Holders of all the Securities, to waive compliance
by PNM and the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences.  Any such consent or waiver
by the Holder of this Bond shall be conclusive  and binding upon such Holder and
upon all  future  Holders  of this  Bond  and of any  Security  issued  upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent or waiver is made upon this Bond.

                  As provided in the Indenture,  the aggregate  principal amount
of Securities which may be issued thereunder is unlimited. The Bonds are limited
in aggregate principal amount to $253,677,000, consisting of:

         Stated Maturity           Interest          Principal
           of Principal              Rate              Amount
           ------------              ----              ------

         July 15, 1991              8.3%            $25,332,000

         July 15, 1996              9.125%          $40,532,000

         January 15, 2014          10.3%           $187,813,000
                                                   ------------
                                                   $253,677,000

                  In the event  that one or more  Leases  are  terminated  under
Section 14 thereof,  the Bonds with Stated  Maturity of principal of January 15,
2014 are subject to mandatory  redemption  in part from time to time on not less
than 20 nor more than 60 days' prior notice  given as provided in the  Indenture
at a redemption  price equal to the principal amount of the Bonds to be redeemed
plus  accrued  interest  to the date fixed for  redemption,  on the same date on
which,  and to the same extent that,  the Pledged  Lessor Notes  relating to the
Bonds are prepaid as provided in Section 5.2 of the Lease  Indenture under which
they were issued.

                  The  Bonds  of each  Stated  Maturity  of  principal  are also
subject to mandatory  redemption pursuant to sinking fund installments,  as more
fully provided in the Indenture, at the principal amount thereof,  together with
interest  accrued  to the date  fixed  for  redemption,  on the dates and in the
respective principal amounts set forth in the Indenture.

                  The sinking  fund  installments  for the Bonds of a particular
Stated  Maturity of principal set forth in the Indenture may be adjusted once at
the discretion of the Company prior to July 15, 1988, in connection with certain
adjustments in basic rent pursuant to any of the Leases; provided, however, that
no such  adjustments  shall be made by the Company which will increase or reduce
the average life of such Bonds (calculated in accordance with generally accepted
financial  practice  from the date of initial  issuance  thereof) by more than 6
months.

                  As provided in the Indenture, in connection with any mandatory
sinking fund  redemption of Bonds of a particular  Stated  Maturity or principal
(other  than Bonds of a Stated  Maturity of  principal  of July 15,  1991),  the
Company may cause the Trustee first to select for such redemption  Bonds of such
Stated Maturity of principal held by PNM or any Affiliate of PNM.

                  In  the  event  of  any  partial  redemption  of  Bonds  of  a
particular   Stated   Maturity  of  principal   (other  than   pursuant  to  the
aforementioned  sinking  fund),  the  principal  amount of Bonds of such  Stated
Maturity of  principal  to be redeemed  thereafter  pursuant to the sinking fund
schedule indicated in the Indenture shall be adjusted  proportionately as nearly
as practicable in accordance with Section 7.01 of the Indenture.

                  In  addition,  the  Bonds  (other  than  Bonds  with a  Stated
Maturity of principal of July 15, 1991) are subject to  redemption,  in whole or
in part, at any time, at the option of the Company,  with monies  deposited with
the Trustee, on not less than 20 nor more than 60 days' notice given as provided
in the Indenture,  at the following redemption prices (expressed as a percentage
of  principal  amount),  together  with  interest  accrued to the date fixed for
redemption as follows:

                  Bonds with a Stated Maturity of principal of July 15, 1996 may
         be redeemed at a price of 109.125%  of the  principal  amount  thereof,
         such  percentage  to decline by 1.304 on July 15,  1987 and each second
         anniversary  thereof  and by  1.303 on July  15,  1988 and each  second
         anniversary thereof,  until such date as such percentage shall be 100%,
         and thereafter 100%; and

                  Bonds with a Stated  Maturity of principal of January 15, 2014
         may be redeemed at a price of 110.3% of the principal  amount  thereof,
         such  percentage  to  decline  by  .412  on  July  15,  1987  and  each
         anniversary thereof,  until such date as such percentage shall be 100%,
         and thereafter 100%;

provided, however, that no such redemption shall be made prior to July 15, 1991,
directly  or  indirectly,  as a part of,  or in  anticipation  of any  refunding
operation  involving the incurrence of indebtedness by the Company,  any Lessor,
PNM or any  Affiliate  of any  thereof  if such  indebtedness  has an  effective
interest cost to the Company,  such Lessor,  PNM or such Affiliate,  as the case
may be (computed in accordance with generally accepted financial  practice),  of
less  than  9.125%  per  annum in the case of Bonds  with a Stated  Maturity  of
principal  of July 15,  1996,  and 10.3%  per annum in the case of Bonds  with a
Stated Maturity of principal of January 15, 2014.

                  In the  case  of any  redemption  of  Bonds,  unpaid  interest
installments whose Stated Maturity, as defined in the Indenture,  is on or prior
to the date fixed for redemption will be payable to the Holders of such Bonds or
one or more  Predecessor  Securities  of record at the close of  business on the
relevant Regular or Special Record Date referred to on the face hereof.

                  The  Indenture  provides that Bonds of a  denomination  larger
than $1,000 may be redeemed in part ($1,000 or an integral multiple thereof) and
that upon any partial  redemption of any such Bond the same shall be surrendered
at the  corporate  trust  office of the Paying Agent in exchange for one or more
new Bonds for the unredeemed portion thereof.

                  Bonds (or portions  thereof as aforesaid) for whose redemption
and payment  provision is made in accordance  with the Indenture shall thereupon
cease  to be  entitled  to the lien of the  Indenture  and  shall  cease to bear
interest from and after the date fixed for redemption.

                  If an Event of  Default,  as defined in the  Indenture,  shall
occur, the principal of this Bond may become or be declared due and payable,  in
the manner and with the effect provided in the Indenture.

                  This Bond is  transferable  by the registered  owner hereof in
person or by attorney  authorized in writing,  at the corporate  trust office of
the Bond  Registrar,  Chemical  Bank (or if such office is not in the Borough of
Manhattan,  The City of New  York,  at  either  such  office  or an office to be
maintained  in such  Borough),  upon  surrender of this Bond,  and upon any such
transfer  a new Bond of the same  Stated  Maturity  of  principal,  for the same
aggregate  principal  amount,  will be  issued  to the  transferee  in  exchange
herefor.

                  The  Bonds  are  issuable  only as  registered  Bonds  without
coupons in  denominations  of $1,000 and/or any integral  multiple  thereof.  As
provided  in,  and  subject to the  provisions  of,  the  Indenture,  Bonds of a
particular Stated Maturity of principal are exchangeable for other Bonds of such
Stated Maturity, but of a different authorized denomination or denominations, as
requested by the Holder surrendering the same.

                  No service  charge will be made to any Holder of Bonds for any
such transfer or exchange,  but the Bond Registrar may require  payment of a sum
sufficient to cover any tax or other  governmental  charge payable in connection
therewith.

                  Prior to due  presentment for  registration  of transfer,  the
person in whose  name this  Bond is  registered  shall be deemed to be the owner
hereof for the purpose of receiving payment as herein provided and for all other
purposes whether or not this Bond be overdue, regardless of any notice to anyone
to the contrary.

 January 15, 2016                                          11,948,000

                  (b) Selection of Bonds.  The provisions of Section 7.02 of the
Original  Indenture to the  contrary  notwithstanding,  the Trustee  shall first
select for  redemption  on any  Sinking  Fund Date on which  Bonds with a Stated
Maturity of principal of January 15, 2016 are to be redeemed in accordance  with
the Sinking Fund relating  thereto,  such Bonds, if any, of such Stated Maturity
of  principal,  as the Company shall specify (by Bond number) are held by PNM or
an  Affiliate of PNM in a Company  Request  delivered to the Trustee at least 40
(but not more than 90) days prior to such  Sinking  Fund Date and upon which the
Trustee may rely.  Subject to the foregoing,  particular Bonds to be redeemed on
any Sinking Fund Date shall be selected in  accordance  with Section 7.02 of the
Original Indenture.

                  (c) Optional  Adjustment to Sinking Bond Fund for Bonds with a
Stated Maturity of principal of January 15, 2016. The principal  amount of Bonds
with a Stated  Maturity of principal of January 15, 2016 to be redeemed  through
operation  of the  Sinking  Fund for  such  Bonds  may be  adjusted  (upward  or
downward) at the  discretion  of the Company at one time prior to July 15, 1997;
provided,  however,  that no such adjustment  shall be made by the Company which
will increase or reduce the average life of such Bonds (calculated in accordance
with generally accepted financial practice from the date of initial issuance) by
more than two years; provided further, however, such adjustment may only be made
in  connection  with an adjustment to basic rent pursuant to Section 3(d) of one
or more of the Leases  identified  in Schedule 2 hereto or related to the Lessor
Notes  described  in Schedule 3 hereto.  If the Company  shall elect to make the
foregoing adjustment,  the Company shall deliver to the Trustee and PNM at least
60 days prior to the first  Sinking  Fund Date  proposed  to be affected by such
adjustment,  a Company  Request (w) stating that the Company has elected to make
such adjustment in connection  with  adjustments to basic rent under one or more
of such Leases, (x) setting forth a revised schedule of principal amounts of the
Sinking  Fund  applicable  to such  Bonds,  (y)  attaching a copy of the revised
schedules of principal  amortization  for the related  Pledged  Lessor Notes (as
defined in Article II of this  Series  1986B  Bond  Supplemental  Indenture  and
identified in Schedules 2 and 3 hereto) and (z) attaching  calculations  showing
that (i) the average life of such Bonds will not be reduced or increased  except
as permitted by this paragraph (c), (ii) the aggregate  principal  amount of the
Pledged  Lessor Notes  equals the  aggregate  principal  amount of the Bonds and
(iii) the aggregate  amortization of the principal amount of such Pledged Lessor
Notes is sufficient  to repay in full, as and when due, the principal  amount of
such Bonds as and when due,  whether upon  redemption  through  operation of the
applicable  Sinking  Fund or at  maturity.  The Trustee may rely on such Company
Request and shall have no duty with respect to the  calculations  referred to in
the foregoing clause (z) other than to make them available for inspection by any
Holder of such Bonds at the Corporate Trust Office upon reasonable  notice.  The
Trustee shall, at the expense of PNM, send to each Holder of such Bonds at least
20 days  before the first  Sinking  Fund Date to be affected  thereby,  by first
class mail, a copy of such revised schedule of principal amounts of Sinking Fund
payments applicable to such Bonds.

                  (d)  Mandatory   Adjustment  to  Sinking  Funds.   The  second
paragraph  of  Section   7.01  of  the   Original   Indenture  to  the  contrary
notwithstanding,  in the event that there shall have been any partial redemption
of Bonds of a particular  Stated  Maturity of principal  (other than pursuant to
the Sinking Fund), the Sinking Fund payments  thereafter to be made with respect
to such Bonds shall be adjusted as follows. The Company shall first identify all
related Pledged Lessor Notes (as defined in Article II of this Series 1986B Bond
Supplemental  Indenture and  identified in Schedules 2 and 3 hereto)  having the
same  maturity as the Bonds of such  particular  Stated  Maturity  of  principal
redeemed,

if any, which are outstanding following such redemption provided,  however, that
for  purposes of this  Section  1.04(d),  any such  Pledged  Lessor Notes with a
maturity  subsequent  to January  15, 2010 shall be deemed to have a maturity of
January 15, 2016.  Having  identified all such outstanding  Pledged Lessor Notes
(the  Outstanding  Notes),  the Company  shall  determine the dates on which the
principal  of  such  Outstanding   Notes  is  to  be  amortized  (the  Scheduled
Amortization Dates). The amount of the Sinking Fund payment scheduled to be made
on each Sinking  Fund Date  subsequent  to the date of such  partial  redemption
shall  then  be  adjusted  to  equal  the  aggregate  principal  amount  of  all
Outstanding  Notes scheduled to be amortized on the Scheduled  Amortization Date
corresponding  to such Sinking  Fund Date.  All such  adjustments  in respect of
Sinking  Fund  payments  on a Sinking  Fund Date shall be rounded to the nearest
$1,000,  and shall be subject to necessary further  adjustment so that the total
amount of such  reduction  is at least  equal to the total  principal  amount of
Bonds redeemed pursuant to such partial redemption. Having made the calculations
required  by the  preceding  two  sentences,  the Company  shall  deliver to the
Trustee  a  Company  Request  not  later  than 30  days  following  any  partial
redemption of Bonds (other than pursuant to the Sinking Fund), setting forth (x)
the schedules of principal  amortization of all related Outstanding Notes having
the same maturity as the Stated  Maturity of principal of the Bonds redeemed and
(y) a revised  schedule of Sinking Fund payments  applicable to Bonds having the
same Stated Maturity of principal as the Bonds redeemed. The Trustee may rely on
such Company  Request and shall have no duty with respect to the adjustments set
forth  therein other than to make them  available for  inspection by a Holder of
Bonds at the Corporate Trust Office upon reasonable notice.

                  (e) Redemption  Price. The Redemption Price for any Bond to be
redeemed  pursuant  to Section  1.04(a) of this Series  1986B Bond  Supplemental
Indenture shall be 100% of the principal  amount thereof,  together with accrued
interest to the Redemption Date.


                                   ARTICLE II.

                             PLEDGE OF LESSOR NOTES

shall  hereafter be  subjected  to the Lien of the Original  Indenture by one or
more  Supplemental  Indentures of Pledge, in the form attached hereto as Exhibit
A, referred to as the Pledged Lessor Notes).

identified on Schedule 2 hereto unto the Trustee and its  successors and assigns
forever, in trust and for the uses and purposes and subject to the covenants and
conditions set forth in the Indenture.

sale of the Securities of such series at the time on deposit with the Trustee as
part of the  Pledged  Property,  together  with any  income  and gains  from the
investment and  reinvestment  thereof,  and sell any Permitted  Investments,  in
either case, at such prices,  including  accrued  interest,  as are set forth in
such  Company  Request,  and  such  Permitted  Investments  shall be held by the
Trustee  until so sold in trust as part of the  Pledged  Property.  The  Trustee

Investments made pursuant to the procedure specified in this subsection (b)."

                  FIRST  PV  FUNDING   CORPORATION,   a   Delaware   corporation
(hereinafter called the "Company", which term includes any successor corporation
under the  Indenture  referred to on the reverse  hereof),  for value  received,
hereby  promises  to pay to the  Registered  Holder  (named  above)  hereof,  or
registered  assigns,  the Principal Amount (stated above) on the Stated Maturity

most  recent  interest  payment  date to which  interest  has been  paid or duly
provided for,  semiannually on July 15 and January 15, in each year,  commencing
January 15, 1987,  at the  Interest  Rate  (stated  above) per annum,  until the
principal hereof is paid in full or made available for payment.  The interest so
payable,  and punctually paid or duly provided for, on any interest payment date
will,  as provided in such  Indenture,  be paid to the person in whose name this
Bond (or one or more  Predecessor  Securities,  as defined in such Indenture) is
registered  at the  close  of  business  on the  Regular  Record  Date  for such
interest, which shall be the June 30 or December 31, as the case may be (whether
or not a Business  Day,  as  defined in such  Indenture),  next  preceding  such
interest payment date. Any such interest not so punctually paid or duly provided
for shall forthwith cease to be payable to the Registered Holder on such Regular
Record  Date,  and may be paid to the  person in whose name this Bond (or one or
more Predecessor Securities) is registered at the close of business on a Special
Record  Date  for the  payment  of such  defaulted  interest  to be fixed by the
Trustee, notice of which shall be given to the Bondholders not less than 10 days
prior to such  Special  Record  Date,  or may be paid at any  time in any  other
lawful manner not inconsistent with the requirements of any securities  exchange
on which the Bonds may be listed,  and upon such  notice as may be  required  by
such  exchange,  all as more fully  provided in such  Indenture.  Payment of the
principal of (and premium, if any) and interest on this Bond will be made at the
corporate trust office of the Paying Agent,  Chemical Bank (or if such office is
not in the Borough of Manhattan,  The City of New York, at either such office or
an office to be  maintained  in such  Borough),  in such coin or currency of the
United  States of America as at the time of payment is legal  tender for payment
of public or private debts, provided that payment of interest may be made at the
option of the  Company by check  mailed to the  address  of the Holder  entitled
thereto as such address shall appear on the Security Register.

                  Interest on any overdue principal and premium, if any, and (to
the extent  permitted by applicable law) any overdue  interest shall be paid, on
demand, from the due date thereof at the rate of interest per annum (computed on
the  basis of a  360-day  year of twelve  30-day  months)  equal to 1% above the
Interest  Rate (stated  above) on this Bond for the period during which any such
principal, premium or interest shall be overdue.

                          FIRST PV FUNDING CORPORATION

                       LEASE OBLIGATION BOND, SERIES 1986B

                  This Bond is one of an  authorized  issue of Securities of the
Company known as its "Lease Obligation Bonds, Series 1986B" (the "Bonds") issued
under,  and all equally and ratably  secured by, a  Collateral  Trust  Indenture
dated as of December 16, 1985 among the Company,  Public Service  Company of New
Mexico, a New Mexico  corporation  (herein called "PNM"),  and Chemical Bank, as
Trustee (herein called the "Trustee",  which term includes any successor Trustee
under the  Indenture),  as  heretofore  supplemented  and amended and as further
supplemented and amended by the Series 1986B Bond  Supplemental  Indenture dated
as of November 18, 1986 among such parties  (collectively,  the  "Indenture") to
which  Indenture  reference is hereby made for a  description  of the nature and
extent of the securities and other property  assigned,  pledged and  transferred
thereunder, the respective rights of the holders of the Bonds and of the Trustee
and the Company in respect of such security,  and the terms upon which the Bonds
are and are to be authenticated and delivered.

                  The principal  of, and premium,  if any, and interest on, this
Bond are payable  from,  and  secured by, the assets  subject to the lien of the
Indenture or the income and proceeds received by the Trustee therefrom,  and all
payments of principal, premium (if any) and interest shall be made in accordance
with the terms of the Indenture.

                  The Indenture and each of the  Participation  Agreements among
an Equity Investor (as hereinafter  defined), a Lessor (as hereinafter defined),
the Company,  the Lease Indenture  Trustee (as hereinafter  defined) and certain
other parties  (each a  "Participation  Agreement")  provide (or, in the case of
each of two of such  Participation  Agreements  to be hereafter  entered into as
contemplated by the Indenture, will upon execution and delivery thereof provide)
that, as and when issued,  certain  Nonrecourse  Promissory  Notes (the "Pledged
Lessor Notes"), in the aggregate principal amount of $460,000,000,  to be issued
by The  First  National  Bank of  Boston,  as owner  trustee  under  one or more
separate Trust Agreements,  with the respective institutional investors named in
such  Trust  Agreements  (The  First  National  Bank of  Boston  in each of such
capacities  as owner  trustee  being  herein  called a  "Lessor"  and each  such
institutional  investor  being  herein  called an  "Equity  Investor"),  will be
included  within the assets  subject to the lien of the  Indenture  pursuant  to
indenture supplements. Such Pledged Lessor Notes are to be issued under separate
documents entitled Trust Indenture,  Mortgage, Security Agreement and Assignment
of Rents,  each  between a Lessor and  Chemical  Bank,  as trustee  (the  "Lease
Indenture  Trustee") (each of such Trust Indentures,  as and when it is executed
and  delivered and as thereafter  amended in  accordance  with its terms,  being
herein called a "Lease  Indenture").  Reference is made to each Lease  Indenture
for a description of the nature and extent of property to be assigned,  pledged,
transferred  and  mortgaged  thereunder  and the rights of the  holders of notes
issued  thereunder,  including  the Pledged  Lessor  Notes.  Except as expressly
provided in a Lease Indenture,  all payments of principal,  premium, if any, and
interest to be made on a Pledged Lessor Note and under such Lease Indenture will
be made only from the assets subject to the lien of such Lease  Indenture or the
income  and  proceeds  received  by  the  Lease  Indenture  Trustee   therefrom,
including,  in the case of each Lease Indenture,  the rights of the Lessor which
is a party thereto to receive basic rentals and certain other  payments  under a
Lease with PNM relating to an undivided interest in certain assets  constituting
part of the Palo Verde  Nuclear  Generating  Station  (also known as the Arizona
Nuclear  Power  Project)  (each of such  Leases,  as and when it is executed and
delivered and as thereafter  amended in accordance with its terms,  being herein
called a "Lease"),  which  basic  rentals  and other  payments  will be at least
sufficient to provide for the payment of the  principal of and premium,  if any,
and interest on each Pledged Lessor Note issued under such Lease Indenture. Each
Holder  hereof,  by its  acceptance  of this  Bond,  agrees  (x) that  except as
expressly  provided above, it will look solely to the assets subject to the lien
of the Indenture or the income and proceeds  received by the Trustee  therefrom,
to the extent available for distribution to the Holder hereof as provided in the
Indenture and (y) that none of an Equity  Investor,  a Lessor, a Lease Indenture
Trustee  or the  Trustee  is liable to the  Holder  hereof or, in the case of an
Equity Investor,  a Lessor and a Lease Indenture Trustee, to the Trustee for any
amounts  payable under this Bond or,  except as provided in the  Indenture  with
respect  to the  Trustee,  for any  liability  under  the  Indenture.  An Equity
Investor  shall not have any duty or  responsibility  under the Indenture or the
Bonds to any Holder or to the Trustee.

                  The  Indenture  permits,  with certain  exceptions  as therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of PNM and  the  Company  and  the  rights  of the  Holders  of the
Securities  under  the  Indenture  at any time by PNM and the  Company  with the
consent of the Holders of not less than a majority in aggregate principal amount
of the  Securities at the time  Outstanding,  as defined in the  Indenture.  The
Indenture  also  contains   provisions   permitting  the  Holders  of  specified
percentages  in  aggregate  principal  amount  of the  Securities  at  the  time
Outstanding, on behalf of the Holders of all the Securities, to waive compliance
by PNM and the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences.  Any such consent or waiver
by the Holder of this Bond shall be conclusive  and binding upon such Holder and
upon all  future  Holders  of this  Bond  and of any  Security  issued  upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent or waiver is made upon this Bond.

                  As provided in the Indenture,  the aggregate  principal amount
of Securities which may be issued thereunder is unlimited. The Bonds are limited
in aggregate principal amount to $460,000,000, consisting of:

           Stated Maturity      Interest             Principal
             of Principal         Rate                 Amount
             ------------         ----                 ------

      January 15, 1992           8.05%               $13,988,000

      January 15, 1997           8.95                $60,347,000

      January 15, 2016          10.15               $385,665,000
                                                    ------------
                                                    $460,000,000

                  In the event  that one or more  Leases  are  terminated  under
Section 14 thereof,  Bonds with a Stated  Maturity of  principal  of January 15,
2016 are subject to mandatory  redemption  in part from time to time on not less
than 20 nor more than 60 days' prior notice  given as provided in the  Indenture
at a redemption  price equal to the principal amount of the Bonds to be redeemed
plus  accrued  interest  to the date fixed for  redemption,  on the same date on
which,  and to the same extent that,  the Pledged  Lessor Notes  relating to the
Bonds are prepaid as provided in Section 5.2 of the Lease  Indenture under which
they were issued.

                  The  Bonds  of each  Stated  Maturity  of  principal  are also
subject to mandatory  redemption pursuant to sinking fund installments,  as more
fully provided in the Indenture, at the principal amount thereof,  together with
interest  accrued  to the date  fixed  for  redemption,  on the dates and in the
respective principal amounts set forth in the Indenture.

                  The sinking fund installments for Bonds with a Stated Maturity
of principal of January 15, 2016 may be adjusted  once at the  discretion of the
Company prior to July 15, 1997, in connection with certain  adjustments in basic
rent pursuant to any of the Leases; provided,  however, that no such adjustments
shall be made by the Company  which will  increase or reduce the average life of
such Bonds (calculated in accordance with generally  accepted financial practice
from the date of initial issuance thereof) by more than two years.

                  As provided in the Indenture, in connection with any mandatory
sinking fund  redemption of Bonds with a Stated Maturity of principal of January
15, 2016, the Company may cause the Trustee first to select for such  redemption
Bonds of such Stated Maturity of principal held by PNM or any Affiliate of PNM.

                  In  the  event  of  any  partial  redemption  of  Bonds  of  a
particular   Stated   Maturity  of  principal   (other  than   pursuant  to  the
aforementioned  sinking  fund),  the  principal  amounts of Bonds of such Stated
Maturity of  principal  to be redeemed  thereafter  pursuant to the sinking fund
schedule  indicated in the Indenture  shall be adjusted in  accordance  with the
Indenture.

                  As  provided in the  Indenture,  in the event that the Company
shall fail to pledge certain  Nonrecourse  Promissory  Notes included within the
term  "Pledged  Lessor Notes" (the "Lessor  Notes") in the  aggregate  principal
amount of $88,000,000 (and otherwise as required by the Indenture),  on or prior
to January 25, 1987, Bonds will be redeemed as provided in the Indenture

the  Indenture)  in  the  aggregate  amount  equal  to  the  difference  between

                  In the  case  of any  redemption  of  Bonds,  unpaid  interest
installments whose Stated Maturity, as defined in the Indenture,  is on or prior
to the date fixed for redemption will be payable to the Holders of such Bonds or
one or more  Predecessor  Securities  of record at the close of  business on the
relevant Regular or Special Record Date referred to on the face hereof.

                  The  Indenture  provides that Bonds of a  denomination  larger
than $1,000 may be redeemed in part ($1,000 or an integral multiple thereof) and
that upon any partial  redemption of any such Bond the same shall be surrendered
at the  corporate  trust  office of the Paying Agent in exchange for one or more
new Bonds for the unredeemed portion thereof.

                  Bonds (or portions  thereof as aforesaid) for whose redemption
and payment  provision is made in accordance  with the Indenture shall thereupon
cease  to be  entitled  to the lien of the  Indenture  and  shall  cease to bear
interest from and after the date fixed for redemption.

                  If an Event of  Default,  as defined in the  Indenture,  shall
occur, the principal of this Bond may become or be declared due and payable,  in
the manner and with the effect provided in the Indenture.

                  This Bond is  transferable  by the registered  owner hereof in
person or by attorney  authorized in writing,  at the corporate  trust office of
the Bond  Registrar,  Chemical  Bank (or if such office is not in the Borough of
Manhattan,  The City of New  York,  at  either  such  office  or an office to be
maintained  in such  Borough),  upon  surrender of this Bond,  and upon any such
transfer  a new Bond of the same  Stated  Maturity  of  principal,  for the same
aggregate  principal  amount,  will be  issued  to the  transferee  in  exchange
herefor.

                  The  Bonds  are  issuable  only as  registered  Bonds  without
coupons in  denominations  of $1,000 and/or any integral  multiple  thereof.  As
provided  in,  and  subject to the  provisions  of,  the  Indenture,  Bonds of a
particular Stated Maturity of principal are exchangeable for other Bonds of such
Stated Maturity, but of a different authorized denomination or denominations, as
requested by the Holder surrendering the same.

                  No service  charge will be made to any Holder of Bonds for any
such transfer or exchange,  but the Bond Registrar may require  payment of a sum
sufficient to cover any tax or other  governmental  charge payable in connection
therewith.

                  Prior to due  presentment for  registration  of transfer,  the
person in whose  name this  Bond is  registered  shall be deemed to be the owner
hereof for the purpose of receiving payment as herein provided and for all other
purposes whether or not this Bond be overdue, regardless of any notice to anyone
to the contrary.

                  As  provided in the  Indenture,  the  Indenture  and the Bonds
shall be construed in  accordance  with and governed by the laws of the State of
New York.
