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 is
pursuing 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 -- Competitive Strategy").

       The total  population  of the area served by one or more of the Company's
utility services is estimated to be approximately 1.3 million, of which 53% live
in the greater Albuquerque area.

       For the year ended  December 31, 1996,  the Company  derived 73.1% of its
operating revenues from electric  operations,  25.7% from natural gas operations
and 1.2% from energy services operations.

       As of December 31, 1996, the Company employed 2,739 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, 1996, approximately 342,000 retail electric customers
were served by the Company,  the largest of which  accounted  for  approximately
3.5% of the Company's  total  electric  revenues for the year ended December 31,
1996.

       The Company holds 22 long-term,  non-exclusive  franchise  agreements for
its electric retail  operations,  expiring  between June 1997 and November 2028.
The City of Albuquerque (the "City") franchise expired in early 1992.  Customers
in the area covered by the expired franchise  represent  approximately  43.0% of
the Company's 1996 total electric  operating  revenues,  and no other  franchise
area represents more than 6.6%. These franchises are agreements that provide the
Company access to public  rights-of-way for placement of the Company's  electric

                                        1

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.
(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  1992  through  1996,  retail  KWh sales  have  grown at a
compound annual rate of approximately  4.6%. 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:

       During  1996 and 1995,  the  Company's  sales in the  off-system  markets
accounted  for  approximately  39.1% and 24.9%,  respectively,  of its total KWh
sales and  approximately  17.3% and 11.8% (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 1996, 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 the 1985 power purchase
agreement were unjust,  unreasonable and unduly discriminatory.  SDG&E requested
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 result in 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.

       On March 18, 1996,  SDG&E filed a second  complaint with the FERC against
the Company,  again  alleging  that  charges  under the  agreement  were unjust,
unreasonable and unduly discriminatory.  SDG&E is again requesting that the FERC
investigate  charges under the  agreement.  The Company  responded to the second
complaint on April 26, 1996. The relief under the second complaint is similar to
that requested  under the first  complaint.  The refund period  requested in the
first complaint,  if granted,  would extend for a fifteen month period beginning
December 26, 1993. The refund period  requested under the second complaint would
extend for a fifteen  month  period  beginning  May 17,  1996.  The FERC has not
issued a ruling on either the first or second  complaint  and has not  indicated
when or if either  complaint will be considered.  The Company believes that both
complaints are without merit, and the Company intends to vigorously  resist both
complaints.

       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 its power  demand in 1997.  This will result in a
peak demand in 1997 of 89 MW.

       The Company furnished  firm-requirements wholesale power in New Mexico in
1996 to the cities of Farmington  and Gallup,  and TNP. 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 1996 were approximately 26 MW. 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.  During 1996, TNP purchased 15 MW
and gave  notice that it will  continue to purchase 15 MW in 1997.  TNP has also
provided   notice  of  its  intent  to   terminate   service   after  1998.   No
firm-requirements  wholesale  customer  accounted  for  more  than  1.3%  of the
Company's  total  electric  operating  revenues for the year ended  December 31,
1996.

Sources of Power

       As of December 31, 1996, 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,  expiring in May 2011.  The Company may reduce its purchases from SPS by
25 MW annually  upon three years'  notice.  The Company  provided such notice to
reduce the purchase by 25 MW in 1999 and by an additional  25 MW in 2000.  Also,
the  Company  has 39 MW of  contingent  capacity  obtained  from El Paso under a
transmission  capacity for generation  capacity trade arrangement that increases
up to 70 MW from 1998 through 2003. In addition,  the Company is  interconnected
with  various  utilities  for  economy  interchanges  and mutual  assistance  in
emergencies.

                                        3

       The  Company  anticipates  the  need for  approximately  100 to 200 MW of
additional  capacity in the 1998 through 2000  timeframe.  To meet this need, on
October 4, 1996, the Company  entered into a long-term  power purchase  contract
with the Cobisa-Person Limited Partnership ("PLP") to purchase approximately 100
MW of unit contingent  peaking capacity from a gas turbine generating unit for a
period of 20 years,  with an option to renew for an additional  five years.  The
gas turbine  generating unit will be constructed and operated by PLP and will be
located on the  Company's  retired  Person  Generating  Station  site located in
Albuquerque,  New Mexico.  The site for the generating unit was chosen, in part,
to provide needed  benefits to the Company's  constrained  transmission  system.
Depending on the regulatory  timing of NMPUC and FERC approvals and the securing
of necessary  permits,  construction  could start in August 1998 with commercial
operation beginning by May 1999. The operational date was chosen to satisfy both
resource and transmission  needs for the Company's  jurisdictional  load. During
October  1996,  the Company  filed a request for approval from the NMPUC and PLP
filed its  application for requisite state  commission  determinations  from the
NMPUC.  These two applications were consolidated by the NMPUC. In December 1996,
the NMPUC established a procedural  schedule for the consolidated  applications.
The  Company  and PLP have  requested  a final  order from the NMPUC by July 31,
1997.  Thereafter,  certain  actions from the FERC will be  required,  including
approval of PLP's status as an "exempt wholesale  generator" under Section 32 of
the Public Utility Holding Company Act.

       In  addition to the  long-term  power  purchase  contract  with PLP,  the
Company is pursuing  other options to ensure its  additional  capacity needs are
met.

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:

</TABLE>



       The estimated  generation  mix for 1997 is 70.4% coal,  28.9% nuclear and
0.7% 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 114 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

                                        4

<PAGE>


SJGS in the La Plata area of northwestern New Mexico.  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 1997  through
2005.  The average cost of fuel,  including  ash  disposal and land  reclamation
costs,  for SJGS for the years 1994, 1995 and 1996 was 172.1 cents,  184.6 cents
and 167.0 cents,  respectively,  per million BTU ($33.62,  $35.75 and $32.18 per
ton, respectively). For other information related to coal requirements, see PART
II, ITEM 7. -- "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS -- OTHER ISSUES FACING THE COMPANY -- COAL FUEL SUPPLY".

       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 surface  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 1994, 1995 and 1996 at Four Corners
was 125.8  cents,  113.4 cents and 125.9  cents,  respectively,  per million BTU
($22.03, $20.04 and $22.90 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. 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

                                        5

<PAGE>


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.  The DOE has announced that it
is not likely to have an operating permanent repository facility before 2015. In
December 1996, DOE sent a letter to the contract holders including APS, advising
that DOE will not be able to fulfill its contractual obligations to accept spent
fuel by January 31, 1998. Because of the uncertainty as to when DOE will be able
to begin spent fuel  acceptance,  the DOE is inviting  the views of all contract
holders on how the delay can best be accommodated.  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 2002 and to safely store spent fuel until
DOE's scheduled shipments from PVNGS begin.

       Currently,  low-level radioactive waste is being shipped to the low level
waste  repository in Barnwell,  South Carolina.  In addition,  a low-level waste
facility  was built in 1995 at the PVNGS site.  This  facility is being used and
has the capability to store an amount of waste  equivalent to 10 years of normal
operation of PVNGS.

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 USBR ("USBR Contract") 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 formally  initiated the renewal and extension process for requesting
rights   through  the  year  2025.   The  Company  is  actively   conducting  an
environmental assessment with the USBR 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.  In June 1996,  the Navajo
Nation  requested the USBR to withhold renewal of the USBR Contract due to water
shortages  of the Navajo  Indian  Irrigation  Project.  Other tribes in the Four
Corners  area have also  voiced  concern  to the USBR  about the  renewal by the
Company of the USBR Contract.  The Company is currently  involved in discussions
with the Navajo Nation to resolve  concerns  about renewal of the USBR Contract.
The Company is currently unable to predict the outcome of these matters but does
not anticipate any material adverse impact on the Company's  financial condition
or results of operation.

       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
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 401,000 customers as of December 31, 1996. The Albuquerque
metropolitan  area accounts for approximately  54.8% 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'   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 on-system  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.  Additionally,  PNMGS  makes
occasional  gas  sales to  off-system  customers.  Off-system  sales  deliveries
generally  occur  at  interstate  pipeline  interconnects  with  PNMGS'  system.
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,  producers  and end users for  delivery to locations  throughout  the
PNMGS  distribution  systems,  as well as for delivery to interstate  pipelines.
PNMGS  provided  gas  transportation   deliveries  to  approximately  1,050  gas
marketers, producers and end users during 1996.

       For the twelve months ended  December 31, 1996,  PNMGS had  throughput of
approximately  100.1  million  decatherms,   including  sales  of  53.1  million
decatherms to both sales-service  customers and off-system customers.  No single
"sales-service"  customer  accounted for more than 4.4% of PNMGS' therm sales in
1996.  During 1996,  approximately  47.0% of the PNMGS' total gas throughput was
related  to  transportation  gas  deliveries.  PNMGS'  transportation  rates are
unbundled,  and transportation  customers only pay for the service they receive.
PNMGS'  total  operating  revenues for the year ended  December  31, 1996,  were
approximately $227.3 million.  Cost-of-gas revenues, received from sales-service
and  off-system  customers,  accounted for  approximately  45.8% 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 44.1% of PNMGS'
total therm sales in 1996 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  resolved  all of the
producer  litigation and reformed its supply portfolio so that it better matches
the demands of PNMGS' sales-service customers. These reformations allow 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
PNMGS 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 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.

                              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.

Proposed Rulemaking

    On June 5,  1995,  the NMPUC  issued a Notice  of  Inquiry  ("NOI")  seeking
comments  on  whether  and  how  NMPUC  Rule  450,   which   governs   affiliate
transactions, should be revised. On June 3, 1996, the NMPUC issued its Notice of
Proposed  Rulemaking and Order on the NOI proposing certain  amendments to NMPUC
Rule 450 and seeking  comments and  suggested  language  changes to its proposed
amendments by August 5, 1996. The proposed  amendments  would, in effect,  limit
the Company's  non-utility  business  ventures.  The Company  vigorously opposed
these limitations and filed its comments and suggested language changes with the
NMPUC. The Company contends that many of the proposed amendments are unwarranted
or prohibited  under the New Mexico Public  Utility Act. To date,  the NMPUC has
not acted on the comments and suggested language changes it requested.

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  $145 million  stated in 1996 dollars,  including
approximately  $24.0 million (of which $13.7 million has already been  expended)
for Person, Prager and Santa Fe Stations which have been retired.

    The Company is currently recovering estimated  decommissioning costs for its
in-service  fossil-fueled  generating  facilities  through  rates charged to its
NMPUC retail customers.

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.  On  February  13,  1997,  the NMPUC  denied  recovery  of these  same
reservation fees in the ongoing general rate proceeding (see PART II, ITEM 7. --
"MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS  -- OTHER ISSUES  FACING THE COMPANY -- GAS RATE CASE").  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.  In
October 1996, the NMPUC issued an order  establishing a working group  including
the NMPUC staff,  the AG and other New Mexico gas utilities to rewrite the rule.
Several  intervenors  including New Mexico industrial end users and national gas
marketing companies have been allowed to join the working group.

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 permit  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.

Public Regulation Commission

    On November 5, 1996,  New Mexico  voters  approved an amendment to the state
constitution which will replace the present State Corporation Commission and the
NMPUC with a single,  elected five member regulatory  authority.  The new Public
Regulation Commission will be responsible for overseeing registration of all New
Mexico  corporations,  as  well  as  regulating  insurers,   transportation  and
telecommunications  companies,  oil and gas pipelines,  and gas, electric, water
and  sewer  public  utilities  operating  in the  state.  Implementing  the  new
regulatory  structure will require legislation to establish new voting districts
and revise the statutes which now govern the two existing regulatory bodies.

    For other rates and regulation issues facing the Company,  see PART II, ITEM
7. -- "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS
OF OPERATIONS -- OVERVIEW -- OTHER ISSUES FACING THE COMPANY -- GAS RATE CASE --

FILE NEW  RETAIL  ELECTRIC  and GAS RATE CASES and  TRANSMISSION  ISSUES -- FERC
Transmission Issues".

                              ENVIRONMENTAL FACTORS

    The Company, in common with other electric and gas utilities,  is subject to
stringent  regulations for protection of the  environment by state,  Federal and
tribal  authorities.  In addition,  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 to meet environmental  regulations in 1997 and 1998.
However,  in  order  to  achieve  operational  efficiencies,   the  Company  and
participants  decided  to begin a retrofit  environmental  project at SJGS which
will cost the SJGS  participants  approximately  $80  million  over the next two
years.

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 provisions (both sulfur dioxide and nitrogen  dioxide) 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 in 1995,  as
required.  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 to the Company as of this date.

    The  Act  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.  The Commission submitted its findings and recommendations
to the EPA in June 1996.

    The Commission's  recommendations  regarding  stationary sources are to: (i)
implement  existing  Clean Air Act  requirements  through  the year  2000,  (ii)
establish  stationary  source  emission  targets as regulatory  triggers,  (iii)
develop  a plan  for  allocating  trading  credits  under a  regulatory  program
emissions cap, (iv) review compliance with targets and establish incentives, (v)
complete source attribution  studies and (vi) develop an improved monitoring and
accounting system.

    The  Commission  did not recommend any  additional  emission  reductions for
point sources.  The  recommendations  include  monitoring the impact of existing
Clear Air Act  requirements on emission  reductions and the resulting  effect on
visibility,  setting regional targets for SO2 emissions from stationary  sources
for the year 2000 and  developing  a  regulatory  program  to  implement  if the
targets  are  exceeded.  The  regulatory  program  will  most  likely  include a
market-based  trading of emissions  allowances.  The targets and the  regulatory
program  have not yet been  developed;  however,  the Company  does not expect a
material  adverse  effect on the  Company's  financial  condition  or results of
operations.

    In a related matter,  the EPA proposed revisions to the National Ambient Air
Quality  Standards for ozone and particulate  matter.  The nature of and cost of
the impacts of these  proposed  revisions,  if any, to the Company's  operations
cannot be determined at this time; however,  the Company does not anticipate any
material  adverse  impact on the  Company's  financial  condition  or results of
operations.

        *  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,  28.8% by M-S-R,  10.04% by Anaheim,  8.475% by
Farmington,  7.2% by Los Alamos and 7.028% by UAMPS. The Company's net aggregate
ownership in SJGS is 750 MW.

       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.

       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 1996,  PVNGS was operated at a capacity  factor of 89.1% which was
the highest yearly capacity  factor attained at the plant.  This capacity factor
was primarily attributable to record setting low refueling outage days.

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  originally  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  stipulated  with the NMPUC in 1994, the Company
wrote down the purchased  beneficial  interests in 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").

       In October 1996,  the Company  purchased  $200 million of the PVNGS LOBs.
The bonds are held as an investment on the  Company's  books.  For rating agency
purposes,  the PVNGS LOBs are included in the  calculation of the debt to equity
ratio and various financial coverage ratios. The purchase of the $200 million of
PVNGS  LOBs is  treated by the rating  agencies  as a  defeasance  of the bonds,
thereby resulting in an improvement to the ratios.


                                       13

<PAGE>



       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

       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  $147.5  million,  a decrease  from  $157.8  million  based on the
previous 1992 study (both amounts are stated in 1995 dollars).

       The Company  determined  that a supplemental  investment  program will be
needed  as a  result  of both  historical  cost  increases  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.

       Pursuant  to NMPUC  approval,  the  Company  funded an  additional  $12.5
million into the qualified and  non-qualified  funds. The estimated market value
of the trusts, including the current life insurance policies, at the end of 1996
was approximately $25.6 million.

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  for all three units is
approximately $24.3 million, with an annual payment limitation of $3 million per
incident.  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".  If the funds
provided by this  retrospective  assessment  program  prove to be  insufficient,
Congress could impose revenue  raising  measures on the nuclear  industry to pay
claims.

                                       14

<PAGE>



       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,
1997,  a  substantial  portion of which must be  applied  to  stabilization  and
decontamination.  The Company has also secured insurance against portions of the
increased  cost of  generation  or  purchased  power and  business  interruption
resulting from certain accidental outages of any of the three PVNGS units if the
outage  exceeds  21  weeks.  The  Company  is a member  of two  industry  mutual
insurers.  These mutual insurers  provide both the "all-risk" and increased cost
of  generation  insurance  to  the  Company.  In the  event  of  adverse  losses
experienced  by these  insurers,  the Company is subject to an  assessment.  The
Company's  maximum  share of any  assessment is  approximately  $3.9 million per
year.

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 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".)

       In July 1996, the Company and other SJGS participants signed an agreement
to convert the existing flue gas  desulfurization  (SO2  removal)  system at the
SJGS into a much simpler and cost  effective  limestone  system.  The conversion
project will cost the participants  approximately  $80 million over the next two
years.  The NMPUC has been notified of the conversion and expected cost savings.
The NMED  approval of a new air permit for the  limestone  system and a disposal
permit for the mine has been  requested.  Construction  is scheduled to begin in
April 1997 and expected to be completed by the end of 1998.

       As of December 31, 1996, the Company owned, jointly owned or leased 2,803
circuit  miles of  electric  transmission  lines,  5,333  miles of  distribution
overhead lines,  3,299 cable miles of underground  distribution lines (excluding
street lighting) and 226 substations.

                                   NATURAL GAS

       The natural gas property as of December 31, 1996  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,  New Mexico. The transmission systems
consisted  of  approximately  1,277 miles of pipe with  appurtenant  compression
facilities.  The distribution systems consisted of approximately 10,098 miles of
pipe.

       On June 21, 1996, the Company entered into a purchase  agreement with the
DOE for the purchase of  approximately  130 miles of transmission  pipe for $3.1
million for the  transmission  of natural gas to Los Alamos and to certain other
communities in northern New Mexico. The purchase is subject to the DOE providing
right-of-way  satisfactory  to the Company.  The  acquisition by the Company was
approved by the NMPUC in December 1996.  Right-of-way  resolution is expected to
be completed in the first quarter of 1997.

                                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 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
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.  In addition,  the ultimate  outcome of this matter will
not have a material  adverse  effect on the  Company's  financial  condition  or
results of operation.

                           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 -- 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.

                                       16

<PAGE>


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. In April 1996, the participants and the Arizona
Department  of Revenue  reached an agreement  to settle the pending  litigation.
Pursuant to the tentative settlement, the Company will relinquish its claims for
relief with respect to prior years and the  defendants  will not  challenge  the
Court of Appeals decision concerning  prospective relief (for tax years 1996 and
thereafter).

       On July 18, 1996,  the Arizona  legislature  passed,  and the Governor of
Arizona  subsequently  signed,  a $200  million  property  tax  reduction  which
codifies  the terms of the  settlement.  Final  documents  are  currently  being
prepared for the  signatures  of the parties to this  action.  The result of the
legislation  and the  settlement  will be a reduction in the  Company's  Arizona
property  tax of  approximately  $4.0  million  annually  beginning  in 1996 and
extending at least three years, barring any subsequent changes in the applicable
tax law.

                                OTHER PROCEEDINGS

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

       On April 16, 1993, the Company and certain  current and former  employees
of the Company or Meadows ("BCD  parties") 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 Savings and Loan Association ("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.

       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.


                                       17

<PAGE>


       On April 11,  1996,  representatives  of the BCD parties and the FDIC met
with a mediator  to  continue  settlement  discussions.  The  mediation  session
resulted in an  agreement  to settle the case for  approximately  $5.8  million,
approximately  $3.1  million  of  which  would  be paid by the  Company  and the
remainder to be paid by insurance covering the BCD parties. Settlement documents
are being drafted for submission to the Court for approval.  After consideration
of  established  reserves,  the Company  believes that there will be no material
adverse effect on the Company's financial condition or results of operations.

       The Company  continues to believe that all of the claims made by the FDIC
in this case are without  merit but, for  business  reasons,  believes  that the
settlement is in the best interest of the Company.

Republic Savings Bank ("RSB") Litigation

       On July 1,  1996,  in a 7-2  decision  in the case of  United  States  v.
Winstar  Corporation,  the United  States  Supreme  Court ruled that the Federal
government  had breached its  contractual  obligations  with certain  thrifts in
refusing to  recognize  the  accounting  practices of  supervisory  goodwill and
capital  credits.  Contracts had been negotiated  with certain Federal  agencies
providing for the purchase of failing thrifts on the condition that  supervisory
goodwill  and  capital   credits  be  recognized  for  purposes  of  determining
compliance  with  regulatory  capital  requirements.  When Congress  enacted the
Financial  Institutions  Reform,  Recovery and  Enforcement  Act in 1989,  these
accounting practices were prohibited, thus driving otherwise healthy thrifts out
of compliance  with the capital  requirements.  Many,  including RSB, were taken
over and liquidated as a result.

       Meadows  owns  directly a 100%  ownership  interest in  Republic  Holding
Company ("RHC"),  and RSB was a wholly-owned  subsidiary of RHC. Meadows and RHC
have pending before the United States Court of Federal  Claims,  a lawsuit filed
on April 13, 1992, alleging similar  contractual  arrangements to those at issue
in the Winstar case. The Federal  government  has filed a counterclaim  alleging
breach by RHC of its  obligation  to  maintain  RSB's net worth and has moved to
dismiss Meadows' claim for lack of standing.

       RSB was the thrift  organized upon the  acquisition  of Citizens  Federal
Savings and Loan Association and Fireside Federal Savings and Loan  Association,
both Illinois corporations,  in 1985. The plaintiffs invested $17 million of new
capital in the failing  institutions.  The Federal regulators expressly promised
that   approximately  $23  million  of  supervisory   goodwill  created  by  the
transaction  could be accounted for as an intangible  asset to be counted toward
regulatory capital.  Additionally, the regulators promised to allow a $3 million
cash  contribution by the Federal  Savings and Loan Insurance  Corporation to be
recorded as a direct credit to regulatory  capital.  On June 5, 1992, the Office
of Thrift  Supervision  placed  RSB in  receivership  and  appointed  the RTC as
receiver.  On November 6, 1992, RTC sold RSB as a going concern for a premium of
nearly $1  million,  with  approximately  $215.5  million  in assets  and $203.9
million in liabilities.

       The RSB case has been held in abeyance  pending the ruling by the Supreme
Court. The Company  believes that the Winstar  decision  establishes the Federal
government's  liability to Meadows and RHC in the RSB  litigation and the amount
of damages  owed as a result will be  vigorously  litigated.  It is premature to
estimate the amount of recovery, if any, by Meadows and RHC.

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.  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


                                       18

<PAGE>


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 but does not anticipate  any material  adverse impact
on the Company's financial condition or results of operation.

       On January 31, 1997, there were 18,835 holders of record of the Company's
common stock.

       On December 31, 1996, the Company's Board of Directors ("Board") declared
a quarterly cash dividend of 12 cents per share of common stock payable February
21, 1997 to  shareholders  of record as of  February  3, 1997.  This will be the
fourth quarterly dividend to the Company's common shareholders since the Company
reinstated its common stock dividend in May 1996.

       The Board set the dividend  payout  ratio below the  industry  average to
allow for dividend growth in the future and to sustain financial flexibility for
the  Company  to respond  to  potential  opportunities  in the  evolving  energy
marketplace.  The Board had not  declared  cash  dividends on common stock since
1989. In establishing its new dividend  policy,  the Board weighed the Company's
current  financial  position  and  its  future  business  plan,  as  well as the
regulatory and business climate in New Mexico.  Future dividend declaration will
be reviewed  for action by the Board and  coordinated  with  quarterly  earnings
announcements.  The payment of future  dividends  will depend on  earnings,  the
financial condition of the Company, market conditions and other factors.

Cumulative Preferred Stock

       While isolated  sales of the Company's  cumulative  preferred  stock have
occurred in the past,  the Company is not aware of any active trading market for
its  cumulative  preferred  stock.  Quarterly  cash  dividends were paid on each
series of the Company's  cumulative preferred stock at their stated rates during
1996 and 1995.

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

Restructuring the Electric Utility Industry

     The electric  utility  industry  continues to be in 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
levels  continue to  consider  how to promote  competition  among  suppliers  of
electricity and how to provide customers with choice among suppliers.

     At the state level, the Integrated Water and Resource Planning Committee of
the New Mexico State  Legislature  (the "IWRPC") held hearings during 1996 which
focused on the issues related to restructuring  of the electric  industry in New
Mexico.  The Company  participated  extensively  in these  hearings  and, at the
invitation of the IWRPC,  submitted  draft  legislation to be used as a starting
point for the  various  parties to  consider  regarding  the  electric  industry
restructuring.  The draft legislation would allow an electric utility to recover
all of its  prudently  incurred  stranded  costs,  and also  provide  a path for
business  flexibility.  The AG testified that retail  competition  should not be
introduced at this time but, if it is, there should be independent  ownership of
generation,  transmission  and  distribution  facilities,  due to  market  power
concerns.  At its  November  1996  meeting,  the IWRPC  voted  not to  recommend
restructuring   legislation  in  the  1997  session  but  instead  to  recommend
continuation of the IWRPC and a study of the tax effects of  restructuring.  The
IWRPC  also  sent a letter  to the  NMPUC  calling  for no  restructuring  to be
undertaken by the NMPUC without legislative approval. The New Mexico legislative
session is  currently  in progress  and the  Company  will  closely  monitor any
legislative action regarding restructuring of the electric utility industry.

     During  1996,  the NMPUC  conducted  a series of  workshop  meetings in its
"Investigation  of Restructuring  of Regulation of the Electric  Industry in New
Mexico". The Company actively  participated in these workshops and presented the
Company's  position on various  matters related to industry  restructuring.  The
Company provided data and analysis in the areas of market structure, measurement
and collection of stranded  costs,  market power,  potential  changes in Company
structure and issues related to the transition  phase.  In conjunction  with the
workshop  meetings,  the NMPUC ordered all utilities  under its  jurisdiction to
file their  estimates  of  stranded  costs,  absent any  recovery  method  being
adopted,  based on the Texas Public Utility Commission Economic Cost Over Market
("ECOM") model. The Company,  in its filing,  presented two  methodologies:  (i)
using the ECOM  model,  the  Company's  stranded  cost  estimates  run from $657
million  for a 1998 full  retail  access  case to $119  million  for a 2002 full
retail  access  case,  and  (ii)  using a  second  methodology,  based  upon the
difference  between the Company's costs of existing  generation and the costs of
new combined  cycle and  combustion  turbine  units to serve the same load,  the
Company's  costs  above  the  level  of new gas  units,  in 1997  dollars,  were
estimated at $748 million for a 1998 full retail access case to $327 million for
a 2002 full retail access case.  The Company  advised the NMPUC that the results
of the ECOM  model  are  highly  sensitive  to  various  assumptions,  primarily
projections  of  future  gas  prices.  To date,  the  NMPUC has not acted on the
requested information.

     At the  Federal  level,  two  orders  and a Notice of  Proposed  Rulemaking
("NOPR")  related to the provision of transmission  service by public  utilities
were issued in 1996. FERC Order 888,  effective July 9, 1996,  addresses,  among
other things,  numerous subjects related to the terms and conditions under which
public  utilities are required to provide access to  transmission  services,  to
purchase  transmission  service  on  comparable  terms for  their own  wholesale


                                       24

<PAGE>

marketing  activities,  to  recover  stranded  costs  from  departing  wholesale
customers  and to conform  existing  power pool  agreements  to the open  access
provision of the order. All public utilities were required to have filed, by the
effective  date, an Open Access  Transmission  Tariff based on the provisions of
the  order.  In  July  1996,  the  Company  filed  its  compliance  Open  Access
Transmission Tariff under Order 888.

     FERC Order 889,  effective  January 3, 1997,  requires public  utilities to
install and operate an Open Access Same-time  Information System and comply with
certain  standards of conduct among  employees in  transmission  operations  and
wholesale power marketing,  designed to prevent employees of a public utility or
its  affiliates  engaged  in  wholesale   marketing   functions  from  obtaining
preferential  access to  transmission-related  information  or from  engaging in
unduly  discriminatory  business  practices  regarding  access  to  transmission
service.  On January 2, 1997,  the Company  filed with the FERC its Standards of
Conduct report in compliance with provisions of Order 889.

     A  NOPR  relating  to  transmission   capacity   reservation  proposed  the
elimination of the provision of separate "network" and "point-to-point"  service
as provided in Order 888,  providing  all open access  service  under a capacity
reservation  tariff.  Industry comments were submitted to the FERC on October 1,
1996. The FERC has provided no indication of any future activity on the proposed
rulemaking. The Company continues to assess the impact of both the rules and the
potential impact of the proposed rulemaking.

     In July 1996,  legislation  was introduced in the United States Congress to
allow retail  competition  by the year 2000.  Since then, a number of bills have
been drafted for potential  introduction  in Congress.  It is  anticipated  that
these bills will be heavily lobbied by utilities,  industrials, power marketers,
generators, environmental groups, consumer groups and state regulators.

     Although it is currently unable to predict the ultimate outcome of possible
retail wheeling initiatives, the Company has been and will continue to be active
at both the state  and  Federal  levels  in the  public  policy  debates  on the
restructuring  of the electric  utility  industry.  The Company will continue to
work with customers,  regulators and legislators and other interested parties to
find  solutions  that  bring   competitive   benefits  while   recognizing  past
commitments.

Competitive Strategy

     The  Company's  strategy for dealing with  competition  in changing  market
places includes  ongoing cost  reductions,  increased  productivity,  pursuit of
growth opportunities,  seeking to improve credit ratings to investment grade and
strengthening of customer relations. To accomplish these objectives, the Company
continues  to  maintain  the  focus on its  core  business  and is  aggressively
pursuing  its  efforts to expand  its energy  related  business  into  carefully
targeted markets for new business opportunities.

     In pursuing new business  opportunities,  the Company is focusing on energy
and utility related  activities  under its Energy Services  Business Unit. These
activities will provide energy marketing 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  in the Southwest.  The
Energy Services Business Unit is also pursuing business opportunities in Mexico.

     In June  1995,  the  Company  filed  an  application  with  the  NMPUC  for
authorization for the creation of three wholly-owned non-utility subsidiaries as
part of the Energy Services Business Unit. 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. In March 1996, the NMPUC issued an order adopting
the hearing examiner's recommendation and denied NMPUC staff's motion to dismiss
the case. On July 8, 1996, hearings in the case began and were concluded on July


                                       25

<PAGE>


19, 1996.  The NMPUC staff  alleged that certain  activities  undertaken  by the
Company,  that would be transferred to the  subsidiaries if approval is granted,
required  prior  approval  thus leaving the Company  subject to  sanctions.  The
Company currently cannot predict the ultimate outcome of this proceeding but has
and intends to continue to vigorously  defend against any allegation  that it is
in violation of any legal requirements.

     In December 1996, the Company filed an  application  for certain  variances
and  authorization  to  invest  up  to  $7.5  million  of  equity  capital  in a
partially-owned  subsidiary  company  to be  incorporated  under the laws of the
United Mexican States,  and to provide  guarantees,  as necessary,  of up to $10
million that may be required in  connection  with the forming of a subsidiary in
Mexico.  The Company  jointly  with  Triturados  Basalticos  y  Derivados,  S.A.
("Tribasa"),  one of the largest construction  companies in Mexico,  submitted a
bid to develop, design,  construct,  manage and operate natural gas distribution
systems in the cities of Chihuahua, Cuauhtemoc-Anahuac and Delicias in the State
of Chihuahua,  Mexico. If the Company and Tribasa,  and possibly a third entity,
were to be awarded the permit jointly, these companies would be required,  under
Mexican law, to form and capitalize a Mexican  corporation to comply with permit
requirements.  In such event,  the Company would serve as technical  participant
and would be  required  to  maintain a certain  equity  ownership  interest.  On
January 17, 1997, the NMPUC gave the Company conditional approval to proceed. On
February 3, 1997, the Company made its compliance filing pursuant to the NMPUC's
conditional approval.  The Company is currently unable to predict the outcome of
the bid.

     The Company  believes  that  successful  operation  of the Energy  Services
Business Unit  activities  will better  position the Company in an  increasingly
competitive utility environment.  The Company is currently awaiting NMPUC action
on the formation of the energy and non-utility  related  subsidiaries  under the
Company's general diversification plan discussed above.

LIQUIDITY AND CAPITAL RESOURCES

Capital Requirements and Liquidity

     Total capital  requirements  include  construction  expenditures as well as
other major  capital  requirements,  including  retirement  of  long-term  debt,
long-term debt sinking funds and cash dividend  requirements for both common and
preferred  stock.  The  main  focus of the  Company's  construction  program  is
upgrading  generating  systems,  upgrading  and  expanding  the electric and gas
transmission and distribution systems and purchasing nuclear fuel. Total capital
requirements  and  construction  expenditures  for 1996 were $321.0  million and
$103.1 million,  respectively.  Projections for total capital  requirements  and
construction  expenditures  for years  1997-2001  are $914.7  million and $563.7
million,  respectively.  These estimates are under continuing review and subject
to on-going  adjustment.  In conjunction with upgrading  generating systems, the
Company has begun a retrofit  environmental  project at the SJGS which will cost
the Company approximately $40 million during the next two years.

     The  Company's  construction  expenditures  for 1996 were  entirely  funded
through cash generated from operations.  The Company currently  anticipates that
internal cash generation will be sufficient to meet capital  requirements during
1997 through  2001.  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.

     In September 1996, the NMPUC granted the Company's request for the purchase
of up to $300 million of PVNGS LOBs and Eastern  Interconnection Project secured
facility bonds over the next three years. In October 1996, the Company purchased
$200 million of PVNGS LOBs at a premium with accrued interest. In purchasing the
LOBs,   the  Company   borrowed  $100  million   against  the  credit   facility
collateralized by the Company's utility customer accounts receivable and certain
amounts  being  recovered  from gas  customers  relating to certain gas contract
settlements  and utilized $118 million of its cash.  Although the PVNGS LOBs are


                                       26

<PAGE>


off-balance  sheet  debt,  these  outstanding  bonds have been  included  in the
calculation  of the Company's  debt to  capitalization  ratio as well as various
financial coverage ratios by the major rating agencies. The purchase of the LOBS
will not only improve these ratios,  but will also increase earnings in the form
of interest  income.  At the end of 1996,  the Company had $20.3 million in cash
and temporary investments and $100.4 million in short-term borrowings.

     In addition,  at year-end 1996 the Company had $110.6  million of available
liquidity  arrangements,  consisting of $100 million from the  revolving  credit
facility  ("Facility") and $10.6 million in local lines of credit . The Facility
will expire in June 1998 and includes a maximum  allowed debt to  capitalization
ratio of 70%. As of December  31,  1996,  such ratio was 61.7 %,  including  the
PVNGS and EIP leases as debt. The Company  expects to renew the Facility  before
its expiration date.

Financing Capability and Dividend Restrictions

     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.  In September  1996,  Standard &
Poor's Corp. and Moody's Investors  Service,  Inc. upgraded the Company's credit
ratings to one level below  investment  grade.  Duff & Phelps  Credit Rating Co.
maintains an investment grade rating for the Company's first mortgage bonds, but
continues to rate all other  securities of the Company below  investment  grade.
The Company may face  limited  credit  markets and higher  financing  costs as a
result of its securities being rated below investment grade.

     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
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, 1996, based on
the earnings test, the Company could have issued  approximately  $254 million of
additional  first  mortgage  bonds,  assuming  an annual  interest  rate of 8.65
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
9.40 percent,  the Company could have issued $379 million of preferred  stock as
of year-end.

     In  December  1996,  the  Company  refinanced  $23  million  1984  Series A
Pollution  Control Revenue Bonds,  $77.045 million 1977 Series Pollution Control
Revenue Bonds and $65 million 1978 Series A Pollution Control Revenue Bonds with
fixed rates of 6.3%, 6.3% and 5.7%,  respectively.  The maturity dates for these
new bonds are December 2026, December 2016 and December 2016,  respectively.  In
addition,  the Company is currently in the process of  refinancing an additional
$190 million of  pollution  control  revenue  bonds.  On January 21,  1997,  the
Company  received NMPUC approval for the refinancing of such bonds,  and closing
is  anticipated  for late February  1997.  The remaining $60 million of the 1978
Series A Pollution  Control  Revenue Bonds and $40 million of the Company's 1979
Series A Pollution  Control  Revenue  Bonds will be  refinanced as variable rate
bonds in the weekly mode. The initial  variable rate will be determined prior to
closing.  The  remaining  $90  million of the 1979  Series A  Pollution  Control
Revenue Bonds will be refinanced  with a fixed rate of 6.375%.  The total of the
$190 million bonds will mature in April 2022.

     The Company  currently has no requirements  for long-term  financing during
the period of 1997 through 2001. However,  during this period, the Company could
enter into  long-term  financing  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  resumed the payment of cash dividends on common stock starting
in May 1996 and continued a quarterly cash dividend of 12 cents per common share
during 1996.  The Company's  board of directors  reviews the Company's  dividend
policy on a continuing  basis.  The declaration of common dividends is dependent
upon a number of factors  including  earnings  and  financial  condition  of the
Company and market conditions.

     *   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,  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

     Earnings  per share of common  stock were $1.72,  $1.72 and $1.77 for 1996,
1995 and 1994,  respectively.  The sales of the gathering and processing  assets
and the Company's  water  division in 1995 had a significant  positive  earnings
effect in 1995 and impacted 1996 earnings by reducing operating margin, reducing
operating expenses, reducing interest charges and increasing investment income.

     Electric  gross margin  (operating  revenues less fuel and purchased  power
expense)  increased  $23.3 million in 1996 as a result of retail load growth and
warmer than normal weather and increased  off-system sales margin as a result of
improved wholesale power market conditions.

     Electric gross margin  decreased $37.9 million in 1995 from 1994 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.  An  offset to such  decreases  was the  increase  in
revenues resulting from retail load growth.

     Gas gross margin  (operating  revenues  less gas  purchased for resale) was
unchanged  from 1995.  Higher  off-system  sales margin and higher  retail sales
margin as a result of cooler  than  normal  weather  in 1996 were  offset by the
absence of the gas  gathering and  processing  margin in 1996 due to the sale of
the gas assets in 1995.

     Gas gross margin decreased $16.4 million in 1995 from 1994 due to decreased
gas  deliveries  resulting  from warmer than normal  weather in 1995 and reduced
margin as a result of the sale of the gas assets in 1995.

<PAGE>




     Other operation and maintenance  expenses ("O&M")  decreased $.3 million in
1996 from 1995 due to the following:  (i) lower  production O&M expenses of $7.9
million as a result of reduced scheduled  maintenance outages in 1996, decreased
down time in 1996 for refueling outages and lower property taxes in 1996, (ii) a
decrease of $6.3  million in gas  production  and  products  extraction  expense
resulting from the gas assets sale in June 1995, (iii) lower pension and benefit
costs of $4.2 million as a result of an adjustment to the retiree's  health care
costs and (iv) a decrease in water O&M expense of $3.0  million  resulting  from
the sale of the  Company's  water  division in July 1995.  Such  decreases  were
offset by higher administrative and general ("A&G") expense of $21.0 million due
to increased  labor,  increased  office  supplies and expense and higher outside
services.

     Other O&M  expenses  decreased  $12.3  million in 1995 from 1994 due to the
following:  (i) a decrease  of A&G  expense  of $7.5  million  due to  decreased
injuries  and  damages as a result of the  recording  of  worker's  compensation
liability in 1994 and a decrease in temporary  office labor and postage expense,
(ii) a  decrease  in gas  production  and  products  extraction  expense of $6.2
million  resulting  from  the gas  assets  sale in  1995,  (iii) a $4.1  million
decrease in  production  O&M  expenses as a result of a reduction  in  scheduled
maintenance  outage  hours  and (iv) a  decrease  in water O&M  expense  of $2.1
million  resulting from the sale of the Company's  water division in 1995.  Such
decreases  were offset by (i) higher A&G labor  expense of $4.7 million and (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.

     Depreciation and amortization  expenses  decreased $2.7 million from a year
ago as a result of the sale of the  Company's  water  division and gas assets in
1995 and an  adjustment  recorded in 1996 for the over  amortization  of certain
intangible  utility  plant.  Depreciation  and  amortization  expenses  for 1995
increased  $6.7  million  from  1994 as a result  of the  implementation  of new
depreciation rates approved by the NMPUC in November 1994.

     Net other income and deductions decreased $18.8 million from a year ago and
increased $20.3 million in 1995 from 1994. Significant 1996 items, net of taxes,
included the following: (i) a regulatory liability of $10.1 million, (ii) a $1.7
million  write-down  of certain  assets  related to the  Company's  natural  gas
vehicle   program  and  (iii)  an   additional   accrual  of  $1.0  million  for
environmental  liabilities  associated with the 1995 gas assets sale. Offsetting
such decreases was a curtailment  gain of $8.0 million  related to the change of
the Company's  defined  benefit  pension plan and higher interest income of $7.6
million as a result of increased temporary  investments in 1996 and the purchase
of the PVNGS LOBs.

     Significant 1995 items, net of taxes, included the following: (i) a gain of
$12.8 million  recognized  from the gas assets sale, (ii) a gain of $6.4 million
recognized from the sale of the Company's  water division,  (iii) a $2.6 million
adjustment to the carrying costs related to gas take-or-pay  settlement amounts,
(iv) a $1.9  million  insurance  recovery  and (v) the $1.4  million  related to
adjusting  reclamation  reserves for certain mining operations.  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) a
write-off of $3.0 million relating to gas take-or-pay  settlement payments which
were not  recoverable  through  rates,  (ii) an  additional  provision for legal
expenses of $3.6  million and (iii) a gain and  associated  tax benefits of $6.1
million from the sale of generating facilities to UAMPS.

     Net interest  charges  decreased $3.2 million and $12.7 million in 1996 and
1995,  respectively,  as a result of the  retirement of $132.7  million of PVNGS
LOBs in March  1995.  An  offset  to the 1996  decrease  was  higher  short-term
interest  charges  resulting from short-term  borrowings for the purchase of the
PVNGS  LOBs and an  interest  assessment  from the IRS.  In  addition,  the 1995
decrease  included the effect of the retirement of $45 million of first mortgage
bonds in April 1994.

     Preferred  stock  dividend  requirements  decreased  $3.1  million and $2.7
million in 1996 and 1995,  respectively,  as a result of the  retirement  of $64
million of preferred stock in August 1995.

                         OTHER ISSUES FACING THE COMPANY

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 $13.2 million
rate  decrease.  On February 13, 1997, the NMPUC issued a final order in the gas
rate case,  ordering a rate  decrease  of $7.0  million.  In  ordering  the rate
decrease,  among other  things,  the NMPUC  disallowed  the  recovery of certain
regulatory  assets.  The Company strongly disagrees with the NMPUC's final order
and filed an appeal with the New Mexico  Supreme Court on February 17, 1997. The
Company has  evaluated  the impacts of the rate  reduction  and has  established
appropriate  reserves in its 1996 financial  statements,  pending the outcome of
the appeal.

NMPUC ORDER -- THE COMPANY'S JANUARY 1997 PGAC FACTOR VARIANCE REQUEST;
ORDER TO FILE NEW RETAIL ELECTRIC AND GAS RATE CASES

     Due to rapidly rising gas supply costs in December 1996,  PNMGS requested a
variance,  on December 18, 1996,  from the NMPUC to increase its gas cost factor
by more than 10% without a prior  mandatory  hearing.  Pursuant to NMPUC  rules,
PNMGS  implemented the new gas cost factor with its January billing cycle.  This
increase in gas cost along with  increased gas  consumption  and longer  billing
periods for some  customers  resulted in a  substantial  increase to  customers'
bills.  The NMPUC  denied  PNMGS'  variance to increase the factor more than 10%
without a hearing  and held  public  hearings  to  receive  public  comment  and
testimony. These hearings began on January 22 and concluded on January 30, 1997.
The Company provided testimony regarding the higher gas costs.

     The NMPUC issued a final order in this case on February  13,  1997.  In the
order, the NMPUC imposed,  but suspended,  a fine of $2.2 million to the Company
due to an allegedly  incorrect  cost factor (too low) that was filed in November
1996. In addition,  the NMPUC disallowed collection of $1.6 million of gas costs
and ordered an  independent  audit to be conducted to review the Company's  PGAC
factor  calculations  for the period of December 1995 through  January 1997. The
NMPUC also ordered the  docketing of two new  investigations.  The first,  which
requires a Company filing by March 15, 1997, will investigate whether or not the
Company  should  exit  the  merchant  function  in  providing  gas  supplies  to
customers.  The second, will investigate the prudence of the Company's portfolio
strategies and purchase practices. In addition, the NMPUC ordered the Company to
file a new gas rate case by August 1, 1997, and also ordered the Company to file
an electric retail rate case by May 1, 1997.

     In the order,  the NMPUC  accused  the Company of  intentionally  filing an
inaccurate  factor to avoid a hearing,  thus,  impairing the NMPUC's  ability to
investigate  rising gas prices.  The Company strongly disagrees with the NMPUC's
final order and is evaluating  its options,  including  rehearing and a possible
appeal to the New Mexico Supreme Court.

TRANSMISSION ISSUES

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


                                       30

<PAGE>


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. In 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 continued to work with the Navajo
Nation in 1996 to resolve this conflict.

     The  Company  continues  to assess its  options  but will not pursue  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.

FERC Transmission Issues

     In April 1996,  the Company  filed a notice of change in rates for firm and
non-firm transmission  services. The Company also filed two transmission service
tariffs and a market-based  generation  tariff.  The Company  requested that the
rate change filings,  as well as the transmission and generation tariff filings,
be  consolidated  with four Section 206 complaint  proceedings  of four affected
customers,  as  well  as a rate  change  proceeding  related  to  the  Company's
provision of firm transmission  service to EPE. Seven dockets (the "consolidated
dockets") were consolidated for purposes of determining appropriate transmission
service rates.

     In  addition,   two  wholesale  customers  separately  filed  requests  for
transmission  service under Section 211 of the Federal Power Act in 1996. One of
these  customers  notified the Company of its  intention  to  terminate  certain
transmission  service  agreements and the Company filed notice of termination of
this transmission service agreement with the FERC.

     Prior to the scheduled hearings in the case, the parties were able to reach
a negotiated  settlement of the consolidated  dockets,  the transmission service
requests  and  the  Company's  market-based   generation  rate  tariff.  Certain
provisions of the Company's Open Access  Transmission Tariff ("the Tariff") were
also incorporated into the settlement, leaving portions of the Tariff subject to
further FERC review. A stipulation on the settlement  reached by the parties was
filed with the FERC on December  16, 1996.  In  accordance  with the  stipulated
agreement,  the Company  will refund  approximately  $3.7 million of revenues it
collected from the customers  during the time their Section 206 complaints  were
pending. In addition, the Company's firm wholesale transmission service revenues
will be reduced by  approximately  $1.6 million  annually.  The  stipulation was
certified by the  Administrative  Law Judge to the FERC on January 22, 1997. The
Company anticipates that the FERC will take action on the stipulation before the
end of the second  quarter of 1997. The Company does not anticipate any material
adverse  impact on the  Company's  financial  condition or results of operations
from the settlement agreement.

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

Santa Fe Station

     The Company and the NMED have conducted  investigations  of the groundwater
contamination  detected  beneath the former Santa Fe Generating  Station site to
determine  the  source  of  the  contamination.  The  Company  has  been  and is
continuing to cooperate with the NMED regarding site investigations and remedial
planning pursuant to a settlement agreement between the Company and the NMED. In
June 1996, the Company received a letter from the NMED, indicating that the NMED
believes the Company is the source of gasoline contamination in a municipal well
supplying the City of Santa Fe and groundwater  underlying the Santa Fe Station.
Further,  the NMED letter  stated that the Company was  required to proceed with
interim  remediation  of the  contamination  pursuant  to the New  Mexico  Water
Quality Control Commission ("NMWQCC") regulations.

     In July 1996,  the Company filed an appeal with the NMWQCC  protesting  the
determination  and  directives   contained  in  the  NMED's  June  1996  letter.
Subsequently,  negotiation  meetings were conducted  between the Company and the
NMED for a resolution of the groundwater contamination issue.

     On October 3, 1996,  the Company and the NMED  signed an  Amendment  to the
Settlement  Agreement concerning the groundwater  contamination.  As part of the
Amendment,  the Company agreed to spend approximately $1.2 million  ("Settlement
Amount") for certain costs related to sampling,  monitoring, and development and
implementation  of a remediation  plan. The remediation  plan is to be developed
jointly by the Company and the NMED. Since the contamination affects a municipal
well  supplying  the City of Santa Fe, the  cooperation  of the City of Santa Fe
will also be sought in the  development  of the  plan.  The  amended  Settlement
Agreement  does not,  however,  provide  the  Company  with a full and  complete
release from potential  further  liability for  remediation  of the  groundwater
contamination. After the Company has expended the Settlement Amount, if the NMED
can  establish  through  binding  arbitration  that the Santa Fe  Station is the
source of the  contamination,  the Company could be required to perform  further
remediation that is determined to be necessary. The Company continues to dispute
any  contention  that the Santa Fe  Station  is the  source  of the  groundwater
contamination and believes that insufficient data exists to identify the sources
of   groundwater   contamination.   The   Company  has   completed   an  aquifer
characterization  report and a groundwater quality report associated with the 40
day  reactivation  of the  adjacent  Santa Fe supply  well in July and August of
1996.  These reports  strongly  suggest the groundwater  contamination  does not
originate  from the Santa Fe Station  site and has been drawn  under the site by
the pumping of the Santa Fe supply well. In addition, other urban wells in Santa
Fe are likely vulnerable to contamination from off-site sources.  The Company is
working to provide a remedial approach plan by April 1997 in accordance with the
amended Settlement Agreement.

Person Station

     The Company,  in compliance with the NMED's  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 was  assessed  and  results  were
reported to the NMED. The Company 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  Permit,  the Company posted a $5.1 million  performance bond
with a trustee. The remediation program continues on schedule.

Gas Operations

Gas Wellhead Pit Remediation

     The New Mexico Oil Conservation  Commission  issued an order,  effective on
January 14, 1993, that affects the gas gathering  facilities  located in the San
Juan Basin in northwestern  New Mexico.  The BLM has issued a similar order. The
order prohibits the further  discharge of fluids  associated with the production
of natural gas into  unlined  earthen  pits in specified  areas  (designated  as
"vulnerable  areas")  in the  San  Juan  Basin.  The  order  also  required  the
submission of closure plans for the pits where further discharge was prohibited.
The Company has complied with the orders and has submitted and received approval
for pit closures from the New Mexico Oil  Conservation  Division ("OCD") and the
BLM.

     These gas gathering facilities were sold to Williams on June 30, 1995. As a
part of the sale  agreement,  the Company  agreed to cease  discharge to unlined
earthen pits in designated vulnerable areas and to retain the responsibility for
pit  closures for a stated  period of time and to a stated  dollar  amount.  The
Company has assessed the pits in accordance with OCD/BLM directives,  and is now
in the process of closing pits and remediating  them, if necessary,  at wellhead
locations  within the designated  vulnerable  areas. The Company has submitted a
groundwater  management  plan to the OCD and has received  approval of the plan,
and  is  proceeding  with  delineation  of  groundwater  contamination  and,  as
necessary,  cleanup,  in  accordance  with the approved  plan.  The Company will
address groundwater contamination within the dollar and time limitations imposed
by the sale agreement with Williams,  and in accordance with the requirements of
the OCD.

     In  March  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.  In 1995,  the  Company  received  a claim  for
indemnification  by Williams,  the  purchaser of the Company's gas gathering and
processing  assets,  for the  environmental  work  required  to comply  with the
Jicarilla  ordinance.  The Company submitted a  closure/remediation  plan to the
Jicarilla,  which was approved.  The Company's  remediation work pursuant to the
plan  commenced  in mid-1996,  and the costs of  remediation  are being  charged
against the $10.6 million indemnification cap contained in the purchase and sale
agreement between the Company and Williams.  The Company met the requirement for
closing  and  remediating  pits  within the  environmentally  sensitive  area by
December 1996, and anticipates closing and remediating all other pits associated
with the gas  gathering  and  processing  assets by the December  1998  deadline
specified in the ordinance.

COAL FUEL SUPPLY

     In July 1996,  the Company was notified by BHP,  fuel supplier to the SJGS,
that the Navajo Nation has proposed to select certain  properties within the San
Juan and La Plata Mines (the "mining  properties")  pursuant to the  Navajo-Hopi
Land Settlement Act of 1974 (the "Act").  The mining  properties are operated by
BHP under  leases  from the BLM and  comprise a portion  of the fuel  supply for
SJGS. An administrative  appeal by BHP is pending.  In the appeal, BHP expressed
concern that transfer of the mining  properties to the Navajo Nation may subject
the mining  operations  to  taxation  and  additional  regulation  by the Navajo
Nation, both of which could increase the price of coal that might potentially be
passed  on to SJGS  through  the  existing  Coal Sale  Agreement.  A stay of all
actions  by the BLM has been  ordered  by the  Interior  Board  of Land  Appeals
pending  resolution of the issues on appeal.  The Company is monitoring  closely
the appeal and other  developments  on this  issue and will  continue  to assess
potential impacts to SJGS and the Company's operations.  Currently,  the Company
is unable to predict the ultimate outcome of this matter but does not believe it
will have a material  adverse  effect on the  Company's  financial  condition or
results of operations.

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  facilities.
The  Company  provides  service  to the  area  which  contributed  43.0%  of the
Company's  total 1996 electric  operating  revenues.  The absence of a franchise
does not change the  Company's  right and  obligation  to serve those  customers
under state law. The Company  continues to collect and pay franchise fees to the
City.

     In 1991,  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.

     In October 1996, a local news media reported that the Mayor of the City had
met with two NMPUC  Commissioners about his concern that state efforts regarding
retail wheeling were proceeding too slowly and that he was evaluating the City's
option to implement  Article XV of the City Charter  requiring  competitive bids
for electric franchises.  The Company has taken the position that the NMPUC does
not have authority to order retail wheeling. (See "OVERVIEW -- Restructuring the
Electric Utility Industry".)

     Although  a  measure  designed  to  start  municipalization  activities  in
Albuquerque was defeated by the City Council, the City continues to maintain its
options by advocating industry restructuring and monitoring the municipalization
activities  of the City of Las Cruces.  In September  1996,  the Court agreed to
decide the question.  In August 1996, in an action brought seeking condemnation,
the  Federal  Magistrate  Court  ruled that the City of Las Cruces had failed to
prove  that  condemnation  would not  materially  impair  service  by El Paso to
customers  outside Las Cruces and  certified  the question of whether  state law
allows condemnation of an electric utility to the Court.

     The Company filed a "friend of the Court" brief in support of El Paso.  The
Court  heard  oral  argument  on  February  11,  1997,  and took the case  under
advisement.  The  Company is  currently  unable to predict  the outcome of these
matters,  but does not anticipate any material impact on the Company's financial
condition or results of operation.

ACCOUNTING FOR THE EFFECTS OF CERTAIN TYPES OF REGULATION

     As  described  in  note 3 to the  consolidated  financial  statements,  the
Company  complies  with the  provisions  of Statement  of  Financial  Accounting
Standards  ("SFAS")  No. 71,  Accounting  for the  Effects  of Certain  Types of
Regulation.  In the event the  Company  determines  that it no longer  meets the
criteria  for  following  SFAS  No.  71,  the  accounting  impact  would  be  an
extraordinary,  non-cash  charge  to  operations  of an  amount  that  could  be
material.  Criteria  that may give  rise to the  discontinuance  of SFAS No.  71
include (1)  increasing  competition  that  restricts the  Company's  ability to
establish prices to recover  specific costs and (2) a significant  change in the
manner in which  rates  are set by  regulators  from  cost-based  regulation  to
another form of regulation.  The Company  periodically reviews these criteria to
ensure that the continuing application of SFAS No. 71 is appropriate. Based on a
current  evaluation of the various  factors and conditions  that are expected to
impact future cost recovery,  the Company  believes that its  regulatory  assets
(net of related regulatory liabilities),  including those related to generation,
are probable of future recovery.

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 1996 dollars and
including installation and replacement power costs) would be approximately $15.3
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.  However, a formal decision as to when to
replace the steam generators has not been made by the PVNGS participants.

ACCOUNTING STANDARDS

     Environmental  Remediation  Liabilities.  Effective  January 1,  1997,  the
Company  will adopt the  provisions  for  Statement  of Position  ("SOP")  96-1,
Environmental  Remediation  Liabilities.  This Statement provides  authoritative
guidance for recognition,  measurement,  display and disclosure of environmental
remediation liabilities in financial statements. The Company previously recorded
environmental liabilities of $24.0 million for its retired fossil-fueled plants.
Approximately  $13.7  million of the $24.0  million  has been  expended  through
December  31,  1996.  The Company  does not expect that the adoption of SOP 96-1
will have a material  impact on the Company's  financial  position or results of
operations.

     Accounting   for   Transfers   and   Servicing  of  Financial   Assets  and
Extinguishment  of  Liabilities.  In June 1996,  FASB issued SFAS No. 125.  This
Statement establishes,  among other things, new criteria for determining whether
a transfer of financial  assets should be accounted for as a sale or as a pledge
of  collateral  in a  secured  borrowing.  SFAS  No.  125 also  establishes  new
accounting  requirements for pledged  collateral.  SFAS No. 125 is effective for
all  transfers  and  servicing  of  financial  assets  and   extinguishments  of
liabilities   occurring   after   December  31,  1996,  and  is  to  be  applied
prospectively, and earlier or retroactive application is not permitted.

     Nuclear Plant Decommissioning.  The staff of the SEC has questioned certain
of the current  accounting  practices of the electric utility industry regarding
the recognition,  measurement and  classification of  decommissioning  costs for
nuclear generating stations in financial  statements of electric  utilities.  In
response  to these  questions,  the FASB has  added a project  to its  agenda to
review 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 1996, and the estimated
cost for  decommissioning  could be  recorded  as a  liability  (rather  than as
accumulated  depreciation),  with  recognition of an increase in the cost of the
related nuclear power plant. The Company does not believe that such changes,  if
required,  would have a material  adverse effect on results of operations due to
the fact that decommissioning  costs related to its two leased nuclear units are
currently being recovered in rates.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

        The  Private  Securities  Litigation  Reform  Act of  1995  (the  "Act")
provides a "safe harbor" for  forward-looking  statements to encourage companies
to  provide  prospective  information  about  their  companies  without  fear of
litigation so long as those statements are identified as forward-looking and are
accompanied by meaningful,  cautionary statements  identifying important factors
that could cause actual results to differ materially from those projected in the
statement.  Accordingly,  the Company hereby identifies the following  important
factors  which  could cause the  Company's  actual  financial  results to differ
materially from any such results which might be projected, forecasted, estimated
or budgeted by the Company in forward-looking statements: (i) adverse actions of
utility  regulatory  commissions,  (ii) utility  industry  restructuring,  (iii)
failure to recover  stranded  assets,  (iv)  failure to obtain new  customers or
retain existing customers, (v) inability to carry out marketing and sales plans,
(vi) adverse impacts  resulting from  environmental  regulations,  (vii) loss of
favorable  fuel supply  contracts,  (viii)  failure to obtain  water  rights and
rights-of-way,   (ix)  operational  and  environmental  problems  at  generating
stations and (x) failure to maintain adequate transmission capacity.

        Many of the  foregoing  factors  discussed  have been  addressed  in the
Company's previous filings with the SEC pursuant to the Securities  Exchange Act
of 1934.  The  foregoing  review of  factors  pursuant  to the Act should not be
construed  as  exhaustive  or  as  any  admission   regarding  the  adequacy  of
disclosures made by the Company prior to the effective date of the Act.

              MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS


         The management of Public Service  Company of New Mexico (the "Company")
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, 1996 and 1995, and the related
consolidated statements of earnings, retained earnings (deficit), and cash flows
for each of the  three  years in the  period  ended  December  31,  1996.  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, 1996 and 1995,  and the results of
their  operations and their cash flows for each of the three years in the period
ended  December  31,  1996 in  conformity  with  generally  accepted  accounting
principles.

              PUBLIC SERVICE COMPANY OF NEW MEXICO AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        December 31, 1996, 1995 and 1994

(1)     Summary of Significant Accounting Policies

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. The Company is also engaged in the operation
and  management  of the City of Santa Fe's  Water  System  and is  pursuing  new
business activities in the energy and utility related services area.

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").

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  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. 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 . Utility plant  includes  certain  electric  assets not subject to
regulation.  The results of operations  of such electric  assets are included in
operating income.

              PUBLIC SERVICE COMPANY OF NEW MEXICO AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                        December 31, 1996, 1995 and 1994


(1)    Summary of Significant Accounting Policies (Continued)

       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:


                                          1996          1995          1994
                                      ------------   -----------   -----------

Electric plant.....................        3.32%         3.32%         3.01%
Gas plant..........................        3.27%         3.21%         3.15%
Water plant (1)....................           --            --         2.68%
Common plant (2)...................           --            --         4.94%

         (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.

       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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                        December 31, 1996, 1995 and 1994


(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
resources excluded from NMPUC retail rates 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.

Investments in Debt and Equity Securities

       Certain  of  the   Company's   other   investments   are   classified  as
Held-to-Maturities  under the terms of SFAS No.  115,  "Accounting  for  Certain
Investments  in Debt and Equity  Securities",  and measured at amortized cost in
the statement of financial position.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                        December 31, 1996, 1995 and 1994


(1)    Summary of Significant Accounting Policies (Continued)

Accounting Standards

       Environmental  Remediation  Liabilities.  Effective  January 1, 1997, the
Company  will adopt the  provisions  of  Statement  of  Position  ("SOP")  96-1,
Environmental  Remediation  Liabilities.  This Statement provides  authoritative
guidance for recognition,  measurement,  display and disclosure of environmental
remediation liabilities in financial statements. The Company previously recorded
environmental liabilities of $24.0 million for its retired fossil-fueled plants.
Approximately  $13.7  million  of the  $24.0  million  has been  expended  as of
December  31,  1996.  The Company  does not expect that the adoption of SOP 96-1
will have a material  impact on the Company's  financial  position or results of
operations.

       Accounting   for  Transfers   and  Servicing  of  Financial   Assets  and
Extinguishment of Liabilities.  In June 1996, the Financial Accounting Standards
Board  ("FASB")  issued SFAS No. 125,  Accounting for Transfers and Servicing of
Financial Assets and Extinguishment of Liabilities.  This Statement establishes,
among other things, new criteria for determining whether a transfer of financial
assets  should  be  accounted  for as a sale or as a pledge of  collateral  in a
secured borrowing. SFAS No. 125 also establishes new accounting requirements for
pledged collateral. SFAS No. 125 is effective for all transfers and servicing of
financial assets and extinguishments of liabilities occurring after December 31,
1996, and is to be applied prospectively, and earlier or retroactive application
is not permitted.

       Nuclear Plant  Decommissioning.  The staff of the Securities and Exchange
Commission has  questioned  certain of the current  accounting  practices of the
electric   utility   industry   regarding  the   recognition,   measurement  and
classification  of  decommissioning  costs for  nuclear  generating  stations in
financial statements of electric utilities. In response to these questions,  the
FASB has added a project to its agenda to review 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 1996, and the estimated cost for  decommissioning  could be
recorded  as  a  liability  (rather  than  as  accumulated  depreciation),  with
recognition of an increase in the cost of the related  nuclear power plant.  The
Company does not believe that such changes,  if required,  would have a material
adverse  effect on results of  operations  due to the fact that  decommissioning
costs related to its two leased nuclear units are currently  being  recovered in
rates.

(2)    Risks and Uncertainties

       The electric utility industry  continues to be in 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
levels  continue to  consider  how to promote  competition  among  suppliers  of
electricity and how to provide customers with choice among suppliers.

                        December 31, 1996, 1995 and 1994


(2)    Risks and Uncertainties (Continued)

       At the state level, the Integrated Water and Resource Planning  Committee
of the New Mexico State  Legislature  (the "IWRPC")  held  hearings  during 1996
which focused on the issues related to restructuring of the electric industry in
New Mexico. The Company  participated  extensively in these hearings and, at the
invitation of the IWRPC,  submitted  draft  legislation to be used as a starting
point for the  various  parties to  consider  regarding  the  electric  industry
restructuring.  The draft legislation would allow an electric utility to recover
all of its  prudently  incurred  stranded  costs  and  also  provide  a path for
business  flexibility.  The AG testified that retail  competition  should not be
introduced at this time but, if it is, there should be independent  ownership of
generation,  transmission  and  distribution  facilities,  due to  market  power
concerns.  At its  November  1996  meeting,  the IWRPC  voted  not to  recommend
restructuring   legislation  in  the  1997  session  but  instead  to  recommend
continuation of the IWRPC and a study of the tax effects of  restructuring.  The
IWRPC  also  sent a letter  to the  NMPUC  calling  for no  restructuring  to be
undertaken by the NMPUC without legislative approval. The New Mexico legislative
session is  currently  in progress  and the  Company  will  closely  monitor any
legislative action regarding restructuring of the electric utility industry.

       During  1996,  the NMPUC  conducted a series of workshop  meetings in its
"Investigation  of Restructuring  of Regulation of the Electric  Industry in New
Mexico". The Company actively  participated in these workshops and presented the
Company's  position on various  matters related to industry  restructuring.  The
Company provided data and analysis in the areas of market structure, measurement
and collection of stranded  costs,  market power,  potential  changes in Company
structure and issues related to the transition  phase.  In conjunction  with the
workshop  meetings,  the NMPUC ordered all utilities  under its  jurisdiction to
file their  estimates  of  stranded  costs,  absent any  recovery  method  being
adopted,  based on the Texas Public Utility Commission Economic Cost Over Market
("ECOM") model. The Company,  in its filing,  presented two  methodologies:  (i)
using the ECOM  model,  the  Company's  stranded  cost  estimates  run from $657
million  for a 1998 full  retail  access  case to $119  million  for a 2002 full
retail  access  case,  and  (ii)  using a  second  methodology,  based  upon the
difference  between the Company's costs of existing  generation and the costs of
new combined  cycle and  combustion  turbine  units to serve the same load,  the
Company's  costs above the level of new gas units were estimated at $748 million
for a 1998 full retail access case to $327 million for a 2002 full retail access
case.  The  Company  advised  the NMPUC  that the  results of the ECOM model are
highly  sensitive to various  assumptions,  primarily  projections of future gas
prices. To date, the NMPUC has not acted on the requested information.

(3)  Regulatory Assets and Liabilities

     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:

     As of December  31, 1996,  substantially  all of the  Company's  regulatory
assets  and  regulatory  liabilities  are being  recovered  in rates  charged to
customers or have been addressed in a regulatory proceeding. If a portion of the
Company's  operations under the NMPUC jurisdiction  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.

(3)  Regulatory Assets and Liabilities (Continued)

     Effective January 1, 1996, the Company adopted SFAS No. 121, Accounting for
the  Impairment of Long-Lived  Assets and  Long-Lived  Assets to be Disposed Of.
This statement  imposes a stricter  criterion for regulatory assets by requiring
that such  assets be probable of future  recovery  at each  balance  sheet date.
Based on the  current  regulatory  structure  in  which  the  Company  operates,
adoption  of this  standard  did not have a  material  impact  on the  Company's
financial position or results of operations.  However,  the Company's ability to
meet the criterion  may change in the future as  competitive  factors  influence
wholesale and retail pricing in this industry.

(4)  Capitalization

     Changes  in  common  stock,   additional  paid-in  capital  and  cumulative

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.

       The aggregate  amounts (in thousands) of maturities for 1997 through 2001
on long-term debt outstanding at December 31, 1996 are as follows:


1997.............................................................. $    14,970

Off-Balance Sheet Items

included in the  calculation  of the  Company's  debt to equity ratio as well as
various financial coverage ratios by the major rating agencies.  The purchase of
the PVNGS LOBs is treated by the rating  agencies as a  defeasance  of the bonds
thereby  resulting in an improvement to these ratios.  The purchase of the PVNGS
LOBs has also increased earnings in the form of interest income.

(7)      Employee and Post-Employment Benefits (Continued)

         In December 1996, the Company's board of directors  approved changes to
the  Company's  defined  benefit  pension plan and  implementation  of a defined
contribution  plan no later  than  January  1, 1998.  As a result,  the  Company
recorded a  curtailment  gain of  approximately  $13.3  million in the financial
statements for the year ended December 31, 1996.

         The  following  sets forth the plan's  funded  status and  amounts  (in
thousands) at December 31:

       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

care  cost  trend  rate  was  8.0%,  8.0%  and 7.5%  for  1996,  1995 and  1994,
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, 1996 by  approximately  $10.4 million and the aggregate  service
and interest  cost  components of net periodic  postretirement  benefit cost for
1996 by approximately $1.1 million. The health care cost trend rate was expected
to decrease to 6.0% by 2010 and to remain at that level thereafter.

(7)    Employee and Post-Employment Benefits (Continued)

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, 1996, was $18.3 million,  of which the  accumulated
and vested benefit  obligation  was $17.4 million.  As of December 31, 1996, the
Company has recognized an additional liability of $2.1 million for the amount of
unfunded  accumulated  benefits  in excess of  accrued  pension  costs.  The net
periodic pension cost for 1996, 1995 and 1994 was $2.1 million, $2.0 million and
$2.2 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
$10.1  million (fair market value of $13.9  million) are presently in trust.  No
additional funds have been provided to the trust since 1989.

Performance Stock Plan

     The Company has a  non-qualifying  stock option  plan,  covering a group of
management employees. Options are granted at the fair market value of the shares
on the date of the grant.  Options granted through December 31, 1995,  vested on
June 30, 1996,  have an exercise term of up to 10 years.  All subsequent  awards
granted after  December 31, 1995,  shall vest three years from the grant date of
the awards and the maximum  number of options are five  million  shares  through
December 31,  2000.  In addition,  the Company has a Director  Restricted  Stock
Retainer  Plan. The number of option shares granted in 1996 under the restricted
stock retainer plan was 4,000 shares with an exercise price of $5.50. No options
under the restricted stock retainer plan were exercised during 1996.

     The option  price of each option grant is  determined  on the date of grant
using  the  Black-Scholes   option-pricing  model  with  the  following  average
assumptions  used for grants in 1995 and 1996,  respectively:  dividend yield of
2.7% and 2.4%;  expected  volatility of 20% and 18%; risk-free interest rates of
5.5% and 5.59%; and expected lives of four years.

     The  Company  applies  APB  Opinion  25,  Accounting  for  Stock  Issued to
Employees,  and related interpretations in accounting for its plan. Accordingly,
no  compensation  cost has been  recognized for its fixed stock option plan. Had
compensation  cost  for  the  Company's  stock  based   compensation  plan  been
determined   consistent   with  SFAS  No.  123,   Accounting   for   Stock-Based
Compensation,  the  effect on the  Company's  pro forma net income and pro forma
earnings per share would not be material.

San Juan Generating Station ("SJGS")

     The Company  operates  and jointly owns SJGS.  At December  31, 1996,  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 Tri-State  Generation and Transmission  Association,

Palo Verde Nuclear Generating Station

     The Company has a 10.2% undivided 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 the 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  for all three units is
approximately $24.3 million, with an annual payment limitation of $3 million per
incident.  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".  If the funds
provided by this  retrospective  assessment  program  prove to be  insufficient,
Congress could impose revenue  raising  measures on the nuclear  industry to pay
claims.

     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,
1997,  a  substantial  portion of which must be  applied  to  stabilization  and
decontamination.  The Company has also secured insurance against portions of the
increased  cost of  generation  or  purchased  power and  business  interruption
resulting from certain accidental outages of any of the three PVNGS units if the
outage  exceeds  21  weeks.  The  Company  is a member  of two  industry  mutual
insurers.  These mutual insurers  provide both the "all-risk" and increased cost
of  generation  insurance  to  the  Company.  In the  event  of  adverse  losses
experienced  by these  insurers,  the Company is subject to an  assessment.  The
Company's  maximum  share of any  assessment is  approximately  $3.9 million per
year.

     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  $147.5  million,  a decrease  from  $157.8  million  based on the
previous 1992 study (both amounts are stated in 1995 dollars).

     The Company  determined  that a  supplemental  investment  program  will be
needed  as a  result  of both  historical  cost  increases  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
regulations, PVNGS Unit 3 will remain in a non-qualified trust.

     Pursuant to NMPUC approval the Company  funded an additional  $12.5 million
into the qualified and  non-qualified  funds.  The estimated market value of the
trusts,  including the current life insurance  policies,  at the end of 1996 was
approximately $25.6 million.

(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 for 1994.

     The Company has a power purchase contract with Southwestern  Public Service
Company  ("SPS") for up to 200 MW,  expiring in May 2011. The Company may reduce
its purchases from SPS by 25 MW annually upon three years'  notice.  The Company
provided  such  notice  to  reduce  the  purchase  by 25 MW in  1999  and  by an
additional 25 MW in 2000.  Also,  the Company has 39 MW of  contingent  capacity
obtained  from El  Paso  Electric  Company  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  capacity in the 1998 through 2000  timeframe.  To meet this need, on
October 4, 1996, the Company  entered into a long-term  power purchase  contract
with the Cobisa-Person Limited Partnership ("PLP") to purchase approximately 100
MW of unit contingent  peaking capacity from a gas turbine generating unit for a
period of 20 years,  with an option to renew for an additional  five years.  The
gas turbine  generating unit will be constructed and operated by PLP and will be
located on the  Company's  retired  Person  Generating  Station  site located in
Albuquerque,  New Mexico.  The site for the generating unit was chosen, in part,
to provide needed  benefits to the Company's  constrained  transmission  system.
Depending on the regulatory  timing of NMPUC and FERC approvals and the securing
of necessary  permits,  construction  could start in August 1998 with commercial
operation beginning by May 1999. The operational date was chosen to satisfy both
resource and transmission  needs for the Company's  jurisdictional  load. During
October  1996,  the Company  filed a request for approval from the NMPUC and PLP
filed its  application for requisite state  commission  determinations  from the
NMPUC.  These two applications were consolidated by the NMPUC. In December 1996,
the NMPUC established a procedural  schedule for the consolidated  applications.
The  Company  and PLP have  requested  a final  order from the NMPUC by July 31,
1997.  Thereafter,  certain  actions from the FERC will be  required,  including
approval of PLP's status as an "exempt wholesale  generator" under Section 32 of
the Public Utility Holding Company Act.

     In addition to the long-term power purchase  contract with PLP, the Company
is pursuing other options to ensure its additional capacity needs are met.

(10)    Lease Commitments

     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.  Covenants  in the
Company's  PVNGS Units 1 and 2 lease  agreements  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.

     Future minimum operating lease payments (in thousands) at December 31, 1996
are:

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

        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

Santa Fe Station

       The Company and the New Mexico  Environmental  Department  ("NMED")  have
conducted  investigations of the groundwater  contamination detected beneath the
former  Santa  Fe  Generating  Station  site  to  determine  the  source  of the
contamination. The Company has been and is continuing to cooperate with the NMED
regarding site  investigations  and remedial  planning  pursuant to a settlement
agreement between the Company and the NMED. In June 1996, the Company received a
letter  from the NMED,  indicating  that the NMED  believes  the  Company is the
source of gasoline contamination in a municipal well supplying the City of Santa
Fe and  groundwater  underlying the Santa Fe Station.  Further,  the NMED letter
stated that the Company was required to proceed with interim  remediation of the
contamination  pursuant  to the New  Mexico  Water  Quality  Control  Commission
("NMWQCC") regulations.

       In July 1996, the Company filed an appeal with the NMWQCC  protesting the
determination  and  directives   contained  in  the  NMED's  June  1996  letter.
Subsequently,  negotiation  meetings were conducted  between the Company and the
NMED for a resolution of the groundwater contamination issue.

       On October 3, 1996,  the Company and the NMED signed an  Amendment to the
Settlement  Agreement concerning the groundwater  contamination.  As part of the
Amendment,  the Company agreed to spend approximately $1.2 million  ("Settlement
Amount") for certain costs related to sampling,  monitoring, and development and
implementation  of a remediation  plan. The remediation  plan is to be developed
jointly by the Company and the NMED. Since the contamination affects a municipal
well  supplying  the City of Santa Fe, the  cooperation  of the City of Santa Fe
will also be sought in the  development  of the  plan.  The  amended  Settlement
Agreement  does not,  however,  provide  the  Company  with a full and  complete
release from potential  further  liability for  remediation  of the  groundwater
contamination. After the Company has expended the Settlement Amount, if the NMED
can  establish  through  binding  arbitration  that the Santa Fe  Station is the
source of the  contamination,  the Company could be required to perform  further
remediation that is determined to be necessary. The Company continues to dispute
any  contention  that the Santa Fe  Station  is the  source  of the  groundwater
contamination and believes that insufficient data exists to identify the sources
of   groundwater   contamination.   The   Company  has   completed   an  aquifer
characterization  report and a groundwater quality report associated with the 40
day  reactivation  of the  adjacent  Santa Fe supply  well in July and August of
1996.  These reports  strongly  suggest the groundwater  contamination  does not
originate  from the Santa Fe Station  site and has been drawn  under the site by
the pumping of the Santa Fe supply well. In addition, other urban wells in Santa
Fe are likely vulnerable to contamination from off-site sources.  The Company is
working to provide a remedial approach plan by April 1997 in accordance with the
amended Settlement Agreement.

Person Station

       The Company,  in compliance with the NMED's  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 was  assessed  and  results  were
reported to the NMED. The Company 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  Permit,  the Company posted a $5.1 million  performance bond
with a trustee. The remediation program continues on schedule.

Gas Operations

Gas Wellhead Pit Remediation

       The New Mexico Oil Conservation  Commission issued an order, effective on
January 14, 1993, that affects the gas gathering  facilities  located in the San
Juan Basin in northwestern New Mexico. The Bureau of Land Management ("BLM") has
issued a similar  order.  The order  prohibits  the further  discharge of fluids
associated  with the  production  of natural gas into  unlined  earthen  pits in
specified areas  (designated as "vulnerable  areas") in the San Juan Basin.  The
order also  required the  submission of closure plans for the pits where further
discharge  was  prohibited.  The  Company has  complied  with the orders and has
submitted  and  received  approval  for pit  closures  from the New  Mexico  Oil
Conservation Division ("OCD") and the BLM.

       These   gas   gathering    facilities   were   sold   to   Williams   Gas
Processing-Blanco  Inc., a subsidiary of Williams Field Services Group, Inc., of
Tulsa Oklahoma  ("Williams")  on June 30, 1995. As a part of the sale agreement,
the Company  agreed to cease  discharge to unlined  earthen  pits in  designated
vulnerable areas and to retain the  responsibility for pit closures for a stated
period of time and to a stated  dollar  amount  (see note 12).  The  Company has
assessed  the pits in  accordance  with  OCD/BLM  directives,  and is now in the
process  of  closing  pits and  remediating  them,  if  necessary,  at  wellhead
locations  within the designated  vulnerable  areas. The Company has submitted a
groundwater  management  plan to the OCD and has received  approval of the plan,
and  is  proceeding  with  delineation  of  groundwater  contamination  and,  as
necessary,  cleanup,  in  accordance  with the approved  plan.  The Company will
address groundwater contamination within the dollar and time limitations imposed
by the sale agreement with Williams,  and in accordance with the requirements of
the OCD.

       Costs (Continued)

       In March  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.  In 1995,  the  Company  received  a claim  for
indemnification  by Williams,  the  purchaser of the Company's gas gathering and
processing  assets,  for the  environmental  work  required  to comply  with the
Jicarilla  ordinance.  The Company submitted a  closure/remediation  plan to the
Jicarilla,  which was approved.  The Company's  remediation work pursuant to the
plan  commenced  in mid-1996,  and the costs of  remediation  are being  charged
against the $10.6 million indemnification cap contained in the purchase and sale
agreement between the Company and Williams.  The Company met the requirement for
closing  and  remediating  pits  within the  environmentally  sensitive  area by
December 1996, and anticipates closing and remediating all other pits associated
with the gas gathering and processing assets by December 1998 deadline specified
in the ordinance.

(12)   Asset Sales

       In 1995, the Company and its subsidiaries sold certain  non-strategic gas
assets for approximately $154 million to Williams, recognizing an after-tax gain
of $12.8  million.  This gain was  adjusted  to $11.8  million in 1996 due to an
accrual for additional gas environmental  costs. Under the NMPUC order approving
the sale,  the Company is required to share  approximately  $35 million from the
sale with  customers,  which will be credited to the customers'  bills over five
years.  After  completion  of the  fifth  year,  the  amount  of  gain  will  be
recalculated to include actual expenses  specified in the agreement,  subject to
NMPUC review.  As of December 31, 1996,  the Company has a remaining  balance of
$22.2  million  for future  years  credit to the  customers.  In  addition,  the
Company,  in 1995,  sold its  water  division  to the City of Santa Fe for $51.2
million  (exclusive  of current  assets  netted  against  current  liabilities),
recognizing a after-tax gain of $6.4 million.  Pursuant to the purchase and sale
agreement,  the Company, through its Energy Service Business Unit, will continue
to operate the water  utility up to four years from the  closing  date for a fee
under a contract with the City of Santa Fe.

* Includes the resources excluded from NMPUC retail rates regulation.

       On June 30, 1995, the Company sold substantially all of the gas gathering
and  processing  assets of the Company and its gas  subsidiaries  and on July 3,
1995, the Company sold its water division (see note 12).

(14)   Subsequent Events

       On  February  13,  1997,  the NMPUC  issued a final order in the gas rate
case,  ordering  a rate  decrease  of $7.0  million.  (See  PART II,  ITEM 7. --
"MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS  -- OTHER ISSUES  FACING THE COMPANY -- GAS RATE CASE and NMPUC ORDER
- -- THE COMPANY'S JANUARY 1997 PGAC FACTOR VARIANCE REQUEST; ORDER TO FILE RETAIL
ELECTRIC  AND GAS RATE CASES" in this  report.) In ordering  the rate  decrease,
among other  things,  the NMPUC  disallowed  the recovery of certain  regulatory
assets. The Company strongly disagrees with the NMPUC's final order and filed an
appeal with the New Mexico  Supreme Court on February 17, 1997.  The Company has
evaluated  the impacts of the rate  reduction  and has  established  appropriate
reserves in its 1996 financial statements, pending the outcome of the appeal.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

                        December 31, 1996, 1995 and 1994


(14)   Subsequent Events (Continued)

       The NMPUC issued a final order in the Company's  January 1997 PGAC Factor
Variance  Request on February 13, 1997.  In the order,  the NMPUC  imposed,  but
suspended,  a fine of $2.2 million to the Company due to an allegedly  incorrect
cost factor (too low) that was filed in November  1996.  In addition,  the NMPUC
disallowed  collection  of $1.6 million of gas costs and ordered an  independent
audit to be conducted to review the Company's PGAC factor  calculations  for the
period of  December  1995  through  January  1997.  The NMPUC also  ordered  the
docketing of two new investigations.  The first, which requires a Company filing
by March 15, 1997, will  investigate  whether or not the Company should exit the
merchant  function in providing  gas  supplies to  customers.  The second,  will
investigate  the prudence of the  Company's  portfolio  strategies  and purchase
practices.  In  addition,  the NMPUC  ordered the Company to file a new gas rate
case by August 1, 1997, and also ordered the Company to file an electric  retail
rate case by May 1, 1997.

   In the  order,  the NMPUC  accused  the  Company of  intentionally  filing an
inaccurate  factor to avoid a hearing,  thus,  impairing the NMPUC's  ability to
investigate  rising gas prices.  The Company strongly disagrees with the NMPUC's
final order and is evaluating  its options,  including  rehearing and a possible
appeal to the New Mexico Supreme Court.

        In the opinion of management of the Company, all adjustments (consisting
   of normal recurring  accruals)  necessary for a fair statement of the results
   of operations for such periods have been included.

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

(1)      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.  The Company  recorded an after-tax  gain of
         $12.8 million,  or 31 cents per share.  The gain amount was adjusted by
         $1.0  million  or two  cents per  share in 1996 due to an  accrual  for
         additional  gas  environmental  costs.  On July 3,  1995,  the  Company
         consummated  the sale of the  Company's  water  division to the City of
         Santa Fe. The Company recorded an after-tax gain of $6.4 million, or 15
         cents per share (see note 12).

(2)      During  the  quarter  ended  December  31,  1996,  the  Company  made a
         provision  for loss of  $10.0  million,  net of tax  ($.24  per  common
         share),  as a result of the gas rate order,  pending the outcome of the
         appeal. In addition, the Company recorded an after-tax curtailment gain
         of $8.0 million  ($.19 per common  share)  related to the change of the
         Company's defined benefit pension plan.

            Renewal Term, an amount equal to one-half of an amount determined by
            dividing the aggregate  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

            Section 3(h)), by 56.

If an  interest  payment  on any Note  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,  any amount  which is to be paid under

            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

            "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

<PAGE>

The Lessor  shall have all  rights,  powers and  remedies  provided  for in this
Facility  Lease,  at law, in equity or otherwise,  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  Excepted  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  nominal  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 Tax Law other  than a Change in respect  of a minimum  tax;  provided,
however, that the aggregate amount of such downward adjustments shall not exceed
the  aggregate  amount  of  such  upward  adjustments.  Adjustments  under  this
paragraph (d) shall be (1) made not more than once a year and (2) limited in the
aggregate to the extent  necessary such that the aggregate  amount of Basic Rent
theretofore and thereafter payable throughout the Basic Lease Term (computed for
such purposes only without regard to any adjustments  theretofore  made pursuant
to Section 3(e)) shall not be more than the following  percentages of Basic Rent
pay able throughout the Basic Lease Term  (calculated as aforesaid):  (i) 22% in
the event that the  Outstanding  Notes have not been  reoptimized  in accordance
with their terms and (ii) 15.5% if the Outstanding  Notes have been  reoptimized
in full in accordance with their terms.

<PAGE>

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
Participant's beneficial interest in the Trust 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
appropriately  adjusted  (upward or downward) to preserve Net Economic Return if
there  is (i) any  issuance  of the  Fixed  Rate  Note,  (ii)  any  Supplemental
Financing, (iii) the payment of Transaction Expenses in an amount which is other
than 2.0% of the Purchase Price or (iv) any change in the Pricing Assumptions.

<PAGE>

            (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 within 90 days after
the Owner  Participant  furnishes  the revised  amounts to the Lessee,  the Loan
participant  the Lessor and the  Indenture  Trustee) 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  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 differs by more than 10% from
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 supplement
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.

<PAGE>

            (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 all 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,  other than
Excepted  Payments,  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 all principal  of, and premium,  if any, and interest then due 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,  "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 (ii) the  aggregate  amount of
interest that would have been due and payable on such Basic Rent Payment Date on
such  Note if such  Note had at all  times  during  the  relevant  period  borne
interest at a rate equal to 10.0% per annum (computed on the basis of the actual
number of days elapsed in a year of 365 or 366 days, as the case may be). If, as
of any Basic Rent Payment Date,  (A) the amount  determined  in accordance  with
clause  (i) of the  immediately  preceding  sentence  shall  exceed  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, rescission, 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 PVNGS Site, PVNGS,
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 PVNGS Site or PVNGS, (iii) any damage to, or removal, abandonment,
decommissioning,  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  PVNGS  Site or  PVNGS,  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 for 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 PVNGS
Site or  PVNGS,  (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  unenforceability  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 Owner Participant,  the Indenture Trustee,  the Collateral Trust
Trustee, the Loan 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,  any Financing Document or any ANPP Project Agreement,  or
any waiver,  action or inaction under or in respect of this Facility Lease,  any
other  Transaction  Document,   any  Financing  Document  or  any  ANPP  Project

<PAGE>

Agreement,  or any  exercise 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 PVNGS Site or PVNGS, or any
part  thereof  or 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  under  Section 6(a) hereof 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,
except in accordance with the express terms hereof. If for any reason whatsoever
this Facility  Lease shall be terminated in whole or in part by operation of law
or otherwise,  except as specifically  provided herein,  the Lessee  nonetheless
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 under
takings of the Lessee  herein shall be  performed at its cost,  expense and risk
unless expressly otherwise stated.  Nothing in this Section 4 shall be construed
as a guaranty by the Lessee of any residual  value in the Undivided  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  appli cable  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.

<PAGE>

            SECTION 5. Return of the Undivided Interest.

            (a) Return of the Undivided Interest. On the Lease Termination Date,
the Lessee will  surrender  possession  of the  Undivided  Interest and the Real
Property  Interest to the Lessor (or to a Person  specified by the Lessor to the
Lessee in writing not less than 6 months  prior to the Lease  Termination  Date)
with full rights as a "Transferee"  and the sole  "Participant"  with respect to
the  Undivided  Interest and the Real  Property  Interest  within the meaning of
Section  15.10 of the ANPP  Participation  Agreement,  and will  furnish  to the
Lessor:  (i)  copies  certified  by a  senior  officer  of  the  Lessee  of  all
Governmental Action necessary to effect such surrender  (including,  but without
limitation, appropriate amendments to the License permitting the Lessor (without
the Lessor being  required to change its business) or such Person to possess the
Undivided  Interest and the Real Property Interest with or without the continued
involvement of the Lessee as Agent),  which Governmental Action shall be in full
force and  effect;  and (ii) an  opinion  of  counsel  (which  may be Mudge Rose
Guthrie Alexander & Ferdon,  Snell & Wilmer or another counsel  experienced with
NRC and other nuclear matters reasonably  satisfactory to the Owner Participant)
to the effect  that (A) the  Lessee has  obtained  all  Governmental  Action and
action under the ANPP Participation Agreement necessary to effect such surrender
by the  Lessee  and  receipt  of  possession  by the Lessor (or to the Person so
specified by the Lessor) and (B) such  Governmental  Action is in full force and
effect. At the time of such return the Lessee shall pay or have paid all amounts
due and  payable,  or to become due and  payable,  by it as an ANPP  Participant
under each and every ANPP Project Agreement  allocable or chargeable (whether or
not  payable  during or after the Lease Term) to the  Undivided  Interest or the
Real Property Interest in respect of any period or periods ending on or prior to
the Lease  Termination  Date  (including,  but without  limitation,  all amounts
payable with respect to any and all discretionary Capital Improvements to Unit 1
or the PVNGS Site approved or authorized  (without the  concurrence of the Owner
Participant)  within  the 3-year  period  preceding  the end of the Lease  Term,
whether or not  implementation  thereof  has been  completed  on or prior to the
Lease  Termination  Date),  and the  Undivided  Interest  and the Real  Property
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 than as
aforesaid),  (ix) and (x) of the  definition  of such term) and in the condition
and state of repair  required by Section 8. In the event that on or prior to the
Lease  Termination  Date  there  shall  have  occurred  a  default  by any  ANPP
Participant (other than the Lessee) under the ANPP  Participation  Agreement and
such default shall not have been cured by the defaulting ANPP Participant,  then
(i) the Lessee  agrees to  indemnify  and hold the Lessor  (and each  successor,
assign and transferee  thereof)  harmless against any and all obligations  under
the ANPP  Participation  Agreement  with  respect to  contributions  or payments
required to be made thereby as a result of such default and (ii) the Lessor (and
each  successor,  assign and transferee  thereof) agrees to reimburse the Lessee
for all amounts paid by the Lessee  pursuant to the foregoing  clause (i) to the
extent,  but only to the extent,  that the Lessor (or such successor,  assign or
transferee)  shall  have  actually  received  proceeds  from  the  sale  of  the
Generation  Entitlement  Share of the defaulting ANPP Participant as a result of
the payment made by the Lessee pursuant to the foregoing clause (i), and, to the
extent the Lessor (or such successor,  assign or transferee) shall have received
such proceeds, the amount to be reimbursed to the Lessee pursuant to this clause
(ii) shall  include  interest  at the Prime Rate from the date of any payment by
the  Lessee   pursuant  to  the  foregoing   clause  (i)  through  the  date  of
reimbursement of such amount pursuant to this clause (ii).

<PAGE>

            (b)  Disposition  Services.  The Lessee  agrees  that if it does not
exercise  its option to renew or  purchase  as  provided  in Sections 12 and 13,
respectively,  then during the last  thirty-six  months of the Lease  Term,  the
Lessee will fully  cooperate  with the Lessor in  connection  with the  Lessor's
efforts to lease or  dispose of the  Undivided  Interest  and the Real  Property
Interest including using the Lessee's  reasonable efforts to lease or dispose of
the  Undivided  Interest and the Real  Property  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.

            SECTION 6. Warranty of the Lessor.

            (a)  Quiet  Enjoyment.  The  Lessor  warrants  that  until the Lease
Termination  Date,  so long as no Event of Default  shall have  occurred  and be
continuing,  the Lessee's use and  possession of Unit 1, including the Undivided
Interest,  shall not be  interrupted  by the Lessor or any Person  claiming  by,
through or under the Lessor, and their respective successors and assigns.

            (b)  Disclaimer  of Other  Warranties.  The  warranty  set  forth in
Section  6(a) is in lieu of all  other  warranties  of the  Lessor  or the Owner
Participant,  whether  written,  oral or implied,  with respect to this Facility
Lease, Unit 1, any Capital Improvement,  the Undivided Interest, PVNGS, the Real
Property  Interest or the PVNGS 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
Participant  shall  be  deemed  to have  made,  and  THE  LESSOR  AND THE  OWNER
PARTICIPANT EACH HEREBY DISCLAIMS, ANY OTHER REPRESENTATION OR WARRANTY,  EITHER
EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER,  INCLUDING, WITHOUT LIMITATION,
THE  DESIGN OR  CONDITION  OF UNIT 1, ANY  CAPITAL  IMPROVEMENT,  THE  UNDIVIDED
INTEREST,  THE REAL  PROPERTY  INTEREST,  THE PVNGS  SITE OR PVNGS,  OR ANY PART
THEREOF,  THE MERCHANTABILITY  THEREOF OR THE FITNESS THEREOF FOR ANY PARTICULAR
PURPOSE,  TITLE TO UNIT 1, ANY CAPITAL IMPROVEMENT,  THE UNDIVIDED INTEREST, THE
REAL  PROPERTY  INTEREST,  THE PVNGS  SITE OR PVNGS,  OR ANY PART  THEREOF,  THE
QUALITY  OF THE  MATERIAL  OR  WORKMANSHIP  THEREOF  OR  CONFORMITY  THEREOF  TO
SPECIFICATIONS,  FREEDOM FROM PATENT OR TRADEMARK INFRINGEMENT OR THE ABSENCE OF
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

<PAGE>

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,
except to the extent otherwise expressly provided in Section 6(a), the foregoing
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
Undivided Interest, PVNGS, the Real Property Interest or the PVNGS Site that may
arise pur suant to any law now or hereafter in effect, or otherwise.

            (c) Enforcement of Certain  Warranties.  The Lessor  authorizes' 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

incorporated  or  installed  in Unit 1. The Lessee  warrants and agrees that the
Lessor's 1.133333% undivided interest in all Capital  Improvements shall be free

Person  with   respect  to  any   destruction,   damage,   loss,   condemnation,
confiscation,  theft or seizure of or  Requisition of Title to or Requisition of
Use of the Undivided  Interest 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 the Undivided  Interest
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.

<PAGE>

            (i) Other Dispositions.  Notwithstanding the foregoing provisions of
this Section 9, 50 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  required  to make the
payments  specified in Section 9(c) or 9(d), 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 an
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,
shall  include all  Indemnitees  as insureds  through an omnibus  definition  of
"insured"  or through  endorsement;  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, 1987,  furnish to the Lessor and the Owner Participant (A) a
report signed by the broker or brokers for the PVNGS  insurance (or if insurance
is placed directly by the Operating Agent, a certificate signed by the Operating
Agent) (i) showing the insurance then main tained by the ANPP  Participants with
respect to PVNGS,  (ii) stating that no premiums are then delinquent,  and (iii)

<PAGE>

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  (or if  insurance  is  placed  directly  by the  Lessee,  a
certificate signed by the Lessee) showing the separate  insurance,  if any, then
maintained  by the Lessee with respect to its interest in PVNGS and stating that
no premiums under such insurance are delinquent; (C) a certificate signed by the
Lessee stating that the insurance maintained by the ANPP participants and by the
Lessee,  identified  on the reports to be delivered  pursuant to clauses (A) and
(B), is in accordance with prudent utility practice within the nuclear industry,
the ANPP  Participation  Agreement and this Section 10; and (D) 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.  Any report by an insurance
broker  with  respect  to  clause  (A)(iii)(1)  may be made in  reliance  upon a
schedule provided by the Lessee (a copy of which shall be attached)  identifying
the  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)(iii)(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 pro
ceeds 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, subject,  however,  to
any priority  allocations of such proceeds to decontamination and debris removal
set forth in the insurance  policies or required  under  Applicable  Law. In the
event that  either the  Operating  Agent or the  Lessee  delivers a  certificate
pursuant to clause (A) or (B) of the foregoing,  the Owner  Participant shall be
entitled to receive (if it so requests and if the insurer will issue the same) a
report from any insurer listed in such certificate.

            (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).

<PAGE>

            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 right of the Indenture Trustee to
any such payments shall be absolute and  unconditional and shall not be affected
by  any  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 one-half of the rental provided in Section 21.

<PAGE>

            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,  an Event of Default
shall have occurred and be continuing or an Event of Loss 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 Market  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 Event. If, at or before the Refunding Date, the
Owner  Participant  shall  reasonably  determine  (in  consultation  with  Owner
Participant's  Special  Counsel  and  Owner  Participant's  Special  New  Mexico
Counsel)  that the  "weighted  annual  lease  payment  factor"  (as such term is
defined in the New Mexico Order and as the same may be reasonably interpreted by
the Owner Participant, in consultation with counsel as aforesaid) for all "Lease
Transactions" (as so defined) exceeds 11.5% or there is a material risk that the
same will  exceed  11.7% and so notifies  the Lessor and the  Lessee,  or if the
Lessee, in its reasonable judgment, determines that such a material risk exists,
then the Lessee shall  purchase  the  Undivided  Interest and the Real  Property
Interest  from the  Lessor,  on a Business  Day  specified  by the Lessor to the
Lessee by not less than 30 days prior notice,  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  purchase  date shall not be a Basic Rent Payment  Date, a pro ration of
Basic Rent to the date of purchase.

<PAGE>

            (d) Purchase of the Undivided Interest;  Payment, Etc. If the Lessee
shall have  elected or be required to purchase  the  Undivided  Interest and the
Real Property Interest pursuant to Section 13(b) or 13(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 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).

<PAGE>

            (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  amount  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
Lessee to obtain bids or otherwise  take any action in connection  with any such
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 (but only if such  purchaser  has obtained all  Governmental
Action by the NRC necessary in connection therewith).

<PAGE>

            (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 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  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 Early  Termination  Date shall cease and
the Lease Term shall end on 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.

            SECTION 15.  Events of Default.

            The term Event of Default,  wherever used herein,  shall mean any of
the following  events (whatever the reason for such Event of Default and whether
it shall be voluntary or involuntary,  or come about or be effected by operation
of  law,  or  be  pursuant  to or in  compliance  with  any  Applicable  Law  or
Governmental Action)

            (i) the Lessee shall fail to make, or cause to be made,  (x) payment
      of Casualty Value,  Termination  Value,  Special Casualty Value or payment
      due  pursuant to exercise of the Cure Option when due,  (y) any payment of
      Basic Rent within 5 Business  Days after the same shall  become due or (z)
      any payment of Supplemental  Rent (other than Casualty Value,  Termination
      Value,  Special  Casualty Value or payment due pursuant to exercise of the
      Cure  Option)  within 20 days after the same shall become due or demanded,
      as the case may be; or

<PAGE>

            (ii) the Lessee  shall fail to  perform  or  observe  any  covenant,
      condition or agreement to be performed or observed by it under  Section 10
      ( b ) ( 3 ) ( i ) , 1 0 ( b )( 3 ) ( i i),10(b) (3) (iii) or 10(b) (3) (v)
      of the Participation Agreement or Section 7, 10 (other than failure of the
      Lessee to cause to be delivered the insurance  certificates  (other than a
      certificate  of the  Lessee)  described  therein)  or 11 of this  Facility
      Lease; or

            (iii) the Lessee  shall fail to perform or observe  any  covenant or
      agreement to be performed or observed by it under  Section  10(b)(3)(viii)
      of the  Participation  Agreement  and such  failure  shall  continue for a
      period of 30 days after  there  shall have been given to the Lessee by the
      Lessor or the Owner  Participant  a notice  specifying  such  failure  and
      requiring  it to be remedied  and stating that such notice is a "Notice of
      Default" hereunder; or

            (iv) the Lessee  shall fail to perform its  agreements  set forth in
      Section 5(a) hereof; or

            (v) the  Lessee  shall fail to  perform  or  observe  any  covenant,
      condition or agreement  (other than  covenants,  conditions  or agreements
      referred to in clauses (i) through (iv) above) to be performed or observed
      by it under this Facility  Lease or any other  Transaction  Document,  and
      such failure shall continue for a period of 30 days after there shall have
      been given to the Lessee by the Lessor or the Owner  Participant  a notice
      specifying  such failure and  requiring it to be remedied and stating that
      such notice is a "Notice of Default" hereunder; or

            (vi) any  representation  or  warranty  made by the  Lessee  in this
      Facility  Lease,  any  other  Transaction  Document  (other  than  the Tax
      Indemnification  Agreement)  or any  agreement,  document  or  certificate
      delivered by the Lessee in connection herewith or therewith shall prove to
      have been incorrect in any material  respect when any such  representation
      or warranty  was made or given and shall remain  material  and  materially
      incorrect at the time in question; or

            (vii) the Lessee shall commence a voluntary case or other proceeding
      seeking liquidation, reorganization or other relief with respect to itself
      or its debts under any bankruptcy,  insolvency or other similar law now or
      hereafter  in effect or seeking the  appointment  of a trustee,  receiver,
      liquidator,  custodian or other similar  official of it or any substantial
      part of its  property,  or  shall  consent  to any such  relief  or to the
      appointment  of or  taking  of  possession  by  any  such  official  in an
      involuntary case or other proceeding commenced against it, or shall make a

      corporate action to authorize any of the foregoing; or an involuntary case
      or  other  proceeding  shall  be  commenced  against  the  Lessee  seeking
      liquidation,  reorganization  or other  relief  with  respect to it or its
      debts  under  any  bankruptcy,  insolvency  or  other  similar  law now or
      hereafter  in effect or seeking the  appointment  of a trustee,  receiver,
      liquidator,  custodian or other similar  official of it or any substantial
      part of its property,  and such involuntary case or other proceeding shall
      remain undismissed or unstayed for a period of 60 consecutive days; or

<PAGE>

            (viii)  final  judgment  for the  payment  of  money  in  excess  of
      $1,000,000  shall be rendered  against the Lessee and the Lessee shall not
      have  discharged the same or provided for its discharge in accordance with
      its terms or  bonded  the same or  procured  a stay of  execution  thereof
      within 60 days from the entry thereof; or

            (ix) (1) a  default  by the  Lessee  under  the  ANPP  Participation
      Agreement  in  consequence  of which the  Lessee's  right to  receive  its
      Generation  Entitlement  Share in PVNGS is  suspended  by the  other  ANPP
      Participants,  or (2) 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,  in good  faith,  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
      provision)  of the ANPP  Participation  Agreement,  such 20  Business  Day
      period shall commence on the date of the final  determination of the board
      of arbitrators under such Section 24; or

            (x) (1) the Lessee  shall fail to pay when due (whether by scheduled
      maturity,  required  (prepayment,  acceleration,  demand or otherwise) any
      Debt (which  term shall mean (A)  indebtedness  for  borrowed  money,  (B)
      obligations  as lessee  under leases and (C)  obligations  under direct or
      indirect  guarantees  in  respect  of,  and  obligations   (contingent  or
      otherwise)  to  purchase or  otherwise  acquire or  otherwise  to assure a
      creditor against loss in respect of, indebtedness or obligations of others
      of the kinds  referred to in clause (A) or (B) above,  in each case if the
      principal amount (or equivalent)  thereof (or in the case of any operating
      lease, an equivalent on the assumption such lease were a lease required to
      be  capitalized  in  accordance   with   generally   accepted   accounting
      principles)  is greater than  $20,000,000  ($5,000,000  in the case of any
      PVNGS  operating  lease)) of the Lessee,  and such failure shall  continue
      after the applicable grace period,  if any,  specified in the agreement or
      instrument  relating  to such  Debt,  but only if the  Lessee  shall  have
      received  notice of such  failure or a  Responsible  Officer of the Lessee
      shall have actual  knowledge  of 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 event or a Responsible Officer of the Lessee shall have
      actual knowledge of such default or event.

            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
this Facility  Lease to be in default by written  notice to such effect given to
the Lessee, and may exercise one or more of the following remedies as the Lessor
in its sole discretion shall elect:

<PAGE>

            (i) the Lessor may, by notice to the  Lessee,  rescind or  terminate
      this Facility Lease;  

            (ii) the Lessor may (x) demand that the Lessee,  and  thereupon  the
      Lessee shall,  return  possession  of the Undivided  Interest and the Real
      Property  Interest  promptly  to the Lessor in the  manner  and  condition
      required by, and  otherwise in  accordance  with the  provisions  of, this
      Facility Lease as if the Undivided Interest and the Real Property Interest
      were being  returned at the end of the Lease Term and the Lessor shall not
      be liable for the  reimbursement  of the Lessee for any costs and expenses
      incurred  by the  Lessee  in  connection  therewith  and  (y)  subject  to
      Applicable Law, enter upon the PVNGS Site and take immediate possession of
      (to the  exclusion  of the Lessee)  the  Undivided  Interest  and the Real
      Property  Interest,  by summary  proceedings  or  otherwise,  all  without
      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 in a
      commercially  reasonable  manner,  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 an amount  equal to 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;  Lessee  shall pay to the Lessor,  on the
      Basic Rent Payment Date  specified in such notice,  as liquidated  damages
      for loss of a bargain  and not as a penalty (in lieu of the Basic Rent due
      after the Basic Rent Payment Date speci fied in such  notice),  any unpaid

<PAGE>

      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 (together with interest on such amount at the
      interest rate  specified in Section  3(b)(iii) from the Basic Rent Payment
      Date specified in such notice to the date of actual  payment) (and, in the
      case of (D) below,  upon  receipt of such payment the Lessor shall (or may
      prior to the receipt of such payment) Transfer to the Lessee the Undivided
      Interest and the Real Property Interest):

                  (A) an amount  equal to the excess,  if any,  of (1)  Casualty
            Value,  computed as of the Basic Rent Payment Date specified in such
            notice,  over  (2) 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 remaining
            useful life of Unit 1, after  discounting  such Fair  Market  Rental
            Value  semi-annually  to present  value as of the Basic Rent Payment
            Date specified in such notice at a rate of 10% per annum;

                  (B) an  amount  equal  to the  excess,  if  any,  of (1)  such
            Casualty Value over (2) the Fair Market Sales Value of the Undivided
            Interest and the Real Property Interest  (determined on the basis of
            the then actual  condition  of Unit 1) as of the Basic Rent  Payment
            Date specified in such notice;

                  (C) an amount equal to the excess,  if any, of (1) the present
            value as of the Basic Rent Payment Date  specified in such notice of
            all installments of Basic Rent 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, 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; or

                  (D) an  amount  equal  to  higher  of (1) the  Casualty  Value
            (Special  Casualty  Value  if  the  Event  of  Default  is an  event
            specified  in clause  (v),  (viii) or (x)(2) of Section 15  hereof),
            computed as of the Basic Rent Payment Date  specified in such notice
            or (2) the Fair Market  Sales Value of the  Undivided.  Interest and
            the Real Property Interest;

            (vi) if the Lessor  shall have sold all the  Undivided  Interest and
      the Real Property  Interest pursuant to clause (iii) above, the Lessor, in
      lieu of  exercising  its rights under clause (v) above with respect to the
      Undivided  Interest  and the Real  Property  Interest  may, if it shall so
      elect,  demand that the Lessee pay to the Lessor and the Lessee  shall pay
      to the Lessor on the date of such sale, as liquidated  damages for loss of
      a bargain  and not as a  penalty  (in lieu of Basic  Rent due for  periods
      commencing  after the next Basic Rent Payment Date  following  the date of
      such  sale),  any unpaid  Basic Rent due through  such Basic Rent  Payment
      Date,  plus the amount of any  deficiency of the Sale  Proceeds  under the
      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; or

<PAGE>

            (vii) in the case of an Event of Default specified in clause (iv) of
      Section  15,  the  Lessor  may  demand,  by  written  notice to the Lessee
      specifying a payment date which shall be not earlier than the date 30 days
      after 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 last
      payment  date,  as  liquidated  damages for loss of a bargain and not as a
      penalty,  any unpaid Rent due through  such last Basic Rent  Payment  Date
      plus an amount (not less than zero)  equal to the Fair Market  Sales Value
      (determined  without  regard to the obligation 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  actual
      condition  of Unit 1)  determined  as of such last Basic Rent Payment Date
      (together  with interest on such amount at the interest rate  specified in
      Section  3(b)(iii)  from such last Basic Rent  Payment Date to the date of
      actual  payment) and upon receipt of such payment the Lessor shall (or may
      prior to the receipt of such payment) Transfer to the Lessee the Undivided
      Interest and the Real  Property  Interest);  provided,  however,  that the
      Lessor may not  exercise  the  foregoing  remedy if the Lessor  shall have
      failed to Transfer the Undivided  Interest and the Real Property  Interest
      to the  bidder  (which  shall  not be the  Lessee or an  Affiliate  of the
      Lessee)  that shall have  submitted  the highest cash bid on or before the
      date on which such Event of Default  arose  excluding,  however,  any such
      cash bid which the  Lessor or the  Owner  Participant  determines  was not
      submitted in good faith, or as to which the bidder fails to certify to the
      Lessor such information as the Lessor or Owner  Participant may reasonably
      request in order to  determine  whether or not such bid was  submitted  in
      good faith (and the Lessor  agrees  that it will,  if and to the extent so
      requested by the Lessee on or after the date 90 days  preceding  such last
      Basic Rent Payment  Date,  use  reasonable  efforts (at the expense of the
      Lessee) for a period  ending on the day 90 days after such last Basic Rent
      Payment Date, to find a Person willing to submit such cash bid;  provided,
      however,  that the  failure of the Lessor to do so shall not  relieve  the
      Lessee of its obligations under this clause (vii)).

            (b) No Release. No rescission 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.

<PAGE>

            (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;  provided,   however,  that
notwithstanding  anything to the contrary set forth in this Facility Lease,  the
remedy set forth in Section  l6(a)(vii)  shall be the sole and exclusive  remedy
under this  Section 16 in the case of an Event of  Default  specified  in clause
(iv) of Section 15, unless the Lessee is in default of its payment  obliga tions
under  Section  16(a)(vii),  in which  case the Lessor  may  exercise  its other
remedies  under Section  16(a);  (except that the maximum  amount payable by the
Lessee  in the  event  of the  exercise  by the  Lessor  of any of the  remedies
provided  for in Section  16(a)(v)  or (vi)  shall not  exceed the total  amount
payable by the Lessee  under  Section  16(a)(vii)  minus the amount  provided in
subclause (2) of clause (A), (B) or (C) of such Section 16(a)(v),  if the Lessor
elects a remedy  speci fied in said  clause (A),  (B) or (C), or the  deficiency
referred to in Section  16(a)(vi),  if the Lessor elects the remedy specified in
Section  16(a)(vi)  hereof).  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,  except to the
extent  expressly  limited by provisions of this Section 16,  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(iii), 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

<PAGE>

(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  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 (so long as
no Default or Event of Default shall have occurred and be  continuing)  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 the Owner  Participant shall have received under Section 5.2
of the Indenture all amounts  required to be paid by the Lessee pursuant to this
paragraph  (e)  (including  interest,   if  any,  thereon  pursuant  to  Section
3(b)(iii)), 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
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 then  Outstanding  and this  Facility  Lease
shall  become a secu rity  agreement  for all  purposes of  Applicable  Law. The
Lessee agrees to Use its best efforts to comply with the  conditions  respecting
its assumption  set forth in Section  3.9(b) of the Indenture and,  failing such
assumption,  agrees to accept a transfer of the Owner Participant's right, title
and  interest  in  the  Trust  Estate   pursuant  to  Section   7(b)(4)  of  the
Participation Agreement.

            SECTION 17.  Notices.

            All  communications  and notices provided for in this Facility Lease
shall be in  writing  and shall be given in person  (with  signed  receipt of an
officer  of the  Owner  Participant  in the  case  of a  delivery  to the  Owner
Participant)  or by means of telex,  telecopy,  or other wire  transmission,  or
mailed by  registered  or  certified  mail,  or  delivered  by express  delivery
service,  addressed  as  provided  in  the  Participation  Agreement.  All  such
communications  and notices  given in such manner shall be effective on the date
of receipt of such communication or notice.

            SECTION 18.  Successors and Assigns.

            This   Facility   Lease,   including  all   agreements,   covenants,
indemnities,  representations and warranties, shall be binding upon and inure to
the benefit of the Lessor and its  successors  and  permitted  assigns,  and the
Lessee and its successors and, to the extent permitted hereby, assigns.

            SECTION 19.  Right to Perform for Lessee.

            If the Lessee  shall fail to make any  payment of Rent to be made by
it,  or  shall  fail to  perform  or  comply  with any of its  other  agreements
contained  herein,  or fail to make any  payment to be made by it under any ANPP
Project  Agreement,  or shall fail to  perform  or comply  with any of its other
agreements  contained  in any ANPP Project  Agreement,  either the Lessor or the
Owner  Participant  may, but shall not be obligated to, tender such payment,  or
effect such  performance or  compliance,  and the amount of such payment and the
amount of all costs and expenses (including, without limitation,  attorneys' and
other  professionals' fees and expenses) of the Lessor or the Owner Participant,
as the case may be,  incurred in connection with such payment or the performance
of or compliance with such agreement, as the case may be, together with interest
thereon at the Penalty Rate, shall be deemed  Supplemental  Rent, payable by the
Lessee upon demand.  In the event that the Lessor or the Owner Participant shall
cure any default by the Lessee under the ANPP Participation Agreement,  then (so
long as an event of Default has occurred and is continuing) the Lessor, together
with each other Person contributing to such cure, shall be entitled (to the full
extent  enforceable in accordance with Applicable Law) to receive the Generation
Entitlement  Share of the Lessee  under the ANPP  Participation  Agreement  (not
limited  to Unit 1),  with each  contributor  to  receive a  percentage  of such
Generation  Entitlement  Share equal to the  percentage of the cure  contributed
thereby.

            SECTION 20.  Additional Covenants.

            The Lessee agrees to comply with and to pay, as  Supplemental  Rent,
all  amounts   payable  by  it  under  the  provisions  of  Section  13  of  the
Participation  Agreement  and under the  provisions  of the Tax  Indemnification
Agreement,  which provisions are incorpo rated herein by this reference as fully
as if set forth in full at this  place.  The  Lessee  agrees to comply  with its
covenants  and  agreements  set  forth  in  Sections  10(b),  14  and  16 of the
Participation  Agreement  and Articles III, IV, V and VI of the  Assignment  and
Assumption  which  covenants  and  agreements  are  incorporated  herein by this
reference as fully as if set forth in full at this place.

            SECTION 21. Lease of Real Property Interest.

            Pursuant to the Deed and the Assignment of Beneficial Interest,  the
Lessee has sold to the  Lessor the Real  Property  Interest.  The Lessor  hereby
grants to the Lessee a leasehold  interest in the Real Property  Interest,  such
leasehold to be coterminous with the lease of the Undivided  Interest  hereunder
and to be at a rent per annum equal to 4.635455% of the Real Estate  Investment,
payable by the Lessee to the Lessor in arrears in equal semiannual  installments
on each Basic Rent Payment Date during the Lease Term.

            SECTION 22.  Amendments and Miscellaneous.

            (a) Amendments in Writing.  The terms of this Facility Lease may not
be waived, altered, modified, amended,  supplemented or terminated in any manner
whatsoever except by written instrument signed by the Lessor and the Lessee.

<PAGE>

            (b) Survival.  (1) All indemnities,  representations  and warranties
contained in this  Facility  Lease and the other  Transaction  Documents and the
Financing  Documents and in any  agreement,  document or  certificate  delivered

applicable  statute of limitations by the Owner Trustee,  the Indenture Trustee,
the Lessee, the Owner Participant,  the Loan Participant or any Indemnitee shall
not affect such  survival.  The  obligations  of the Lessee under Section 20 are
expressly made for the benefit of, and shall be enforceable  by, any Indemnitee,

and  notwithstanding  any assignment by the Lessor of this Facility Lease or any
of its rights  thereunder or any  disposition of all or any part of any interest
in the  Undivided  Interest,  the Real  Property  Interest,  Unit 1 or any other

        Date, the Lessee will (1) surrender possession of the Undivided Interest
        and the Real Property  Interest to the Lessor (or to a Person  specified
        by the Lessor to the Lessee in writing  not less than 6 months  prior to

        hereinafter  defined)  having  arisen  prior to,  or  arising  upon,  or
        immediately following, such surrender and (2) furnish to the Lessor: (i)
        copies  certified by a senior officer of the Lessee of all  Governmental
        Action  necessary  to effect  such  surrender  (including,  but  without
        limitation,  appropriate amendments to the License permitting the Lessor
        (without  the Lessor  being  required  to change its  business)  or such
        Person to possess the Undivided  Interest and the Real Property Interest
        with or without the continued involvement of the Lessee as Agent), which
        Governmental  Action  shall be in full  force  and  effect;  and (ii) an
        opinion of counsel (which may be nudge Rose Guthrie  Alexander & Ferdon,
        Snell & Wilmer or another counsel experienced with NRC and other nuclear

        that (A) the  Lessee has  obtained  all  Governmental  Action and action
        under  the  ANPP  Participation   Agreement  necessary  to  effect  such
        surrender by the Lessee and receipt of  possession  by the Lessor (or by
        the Person so specified by the Lessor) and (3) such Governmental  Action
        is in full force and effect. At the time of such return the Lessee shall
        pay or have paid all  amounts  due and  payable,  or to  become  due and
        payable,  by it as an ANPP Participant under each and every ANPP Project

        after the Lease Term) to the  Undivided  Interest  or the Real  Property
        Interest  in respect of any period or periods  ending on or prior to the
        Lease Termination Date (including,  but without limitation,  all amounts

        concurrence of the Owner Participant) within the 3-year period preceding
        the end of the Lease  Term,  whether or not  implementation  thereof has
        been  completed  on or prior to the  Lease  Termination  Date),  and the
        Undivided  Interest  and the Real  Property  Interest  shall be free and
        clear of all Liens (other than Permitted Liens described in clauses (i),

        the Lease  Termination  Date there shall have  occurred a default by any
        ANPP  Participant  (other than the Lessee) under the ANPP  Participation
        Agreement and such default  shall not have been cured by the  defaulting
        ANPP  Participant,  then (i) the Lessee agrees to indemnify and hold the
        Lessor (and each  successor,  assign and  transferee  thereof)  harmless
        against any and all obligations under the ANPP  Participation  Agreement
        with respect to contributions or payments required to be made thereby as
        a result of such default and (ii) the Lessor (and each successor, assign
        and transferee  thereof)  agrees to reimburse the Lessee for all amounts
        paid by the Lessee  pursuant to the foregoing  clause (i) to the extent,

        result of the  payment  made by the  Lessee  pursuant  to the  foregoing
        clause (i), and, to the extent the Lessor (or such successor,  assign or
        transferee)  shall  have  received  such  proceeds,  the  amount  to  be

        interest  at the Prime  Rate from the date of any  payment by the Lessee
        pursuant to the foregoing  clause (i) through the date of  reimbursement
        of such  amount  pursuant  to this  clause  (ii).  For  purposes of this
        Section 5(a) a  "Price-Anderson  Event" shall mean any Change in, or new
        interpretation  by  Governmental   Authority  having   jurisdiction  of,
        Applicable Law, including without limitation the Price-Anderson Act, the
        Atomic  Energy Act and the  regulations  of the NRC,  in each case as in
        effect on the  Closing  Date,  but only if such change is  specified  in
        clauses (2) (i) through  (iv) of the  definition  of "Deemed Loss Event"
        (other than a change which is specified in clause (A) of the  definition
        of "Acceptable Change")."

                (b)  A new  section  8(g) of the  Facility  Lease is  inserted  
therein,  to read in its  entirety as follows:

                "(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 Rent  Payment Date  occurring  one year
        prior to the end of the Renewal Term, if 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 3(h);

                         (ii) On July 15,  1987 and on each Basic  Rent  Payment
                Date  thereafter  to and  including  January 15, 2016, an amount
                equal to  4.40184%,  of  Facility  Cost,  plus or minus the Rent

If an  interest  payment  on any Note  shall be due on a date other than a Basic
Rent Payment Date, the Lessee shall pay additional Basic Rent on such date in an
amount equal to such interest  payment and such payment of additional Basic Rent

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

                         (1) 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

                Value,  Termination  Value or  Special  Casualty  Value,  and an
                amount equal to 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

                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 or otherwise,  in the case of non-payment of
Basic Rent or Supplemental Rent.

                  (c) Form at 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  Excepted  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 flay,
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  nominal  date
provided in this Facility Lease.

                  (d)  Adjustments  to Rent for  Changes in Tax law.  Basic Rent
shall be adjusted  (upward or downward) to preserve Net Economic Return if there
is any Change in Tax Law. Any adjustments  under this Section 3(d) shall be made
not more than once a year and shall be limited in the  aggregate  to the extent,
if any,  necessary such that the Basic Rent  (excluding  any Rent  Differential)
payable on the Basic Rent Payment Date  immediately  following  such  adjustment
shall not vary from the Basic Rent (excluding any Rent Differential) which would
have been payable on such Basic Rent Payment Date had no adjustments (other than
adjustments to reflect actual  Transaction  Expenses) been made pursuant to this
Section 3(d) or pursuant to Section 3(e),  (i) prior to the  Refunding  Date, by
more  than  14% and  (ii) on at  after  the  Refunding  Date,  by more  than the

11.08%;  provided1  however,  that if, by reason of the  limitation set forth in
clause (i) above,  any adjustment  made prior to the Refunding Date is less than
the  adjustment  that would have been required to preserve Net Economic  Return,
then after the Refunding Date there will be a further upward adjustment to Basic
Rent in order to preserve Net Economic  Return,  subject to the  limitation  set
forth in clause (ii)  above,  and if, by reason of the  limitation  set forth in
clause (i) or (ii) above,  any upward  adjustment  contemplated  by this Section
3(d) was less than the adjustment  that would have been required to preserve Net
Economic  Return,  then  the  amount  of  any  subsequent  downward  adjustments
otherwise  required  hereunder shall be reduced to the extent necessary to cause
the aggregate  effect of such upward  adjustment  and such  subsequent  downward
adjustments to preserve Net Economic Return; and provided further, however, that
no downward adjustments shall be made pursuant to this section 3(4) in excess of
any upward  adjustments  made pursuant to this section 3(d) unless and until the
excess  of the  aggregate  amount  of all  such  downward  adjustments  aver the
aggregate of all such upward adjustments would exceed 1%.

                For purposes of  determining  whether a statutory or  regulatory
change  constitutes a Change in Tax Law, the original Owner Participant shall be
deemed to be the Owner Participant  notwithstanding any transfer of its interest
as such (whether or not permitted by Section 15 of the Participation Agreement),
provided1  however,  that a successor Owner  Participant shall be treated as the
Owner  Participant  for such  purposes if the transfer to such  successor  Owner
Participant  was permitted by Section 15 of the  Participation  Agreement and if
both the original Owner  Participant  and such successor  Owner  Participant are
members of the same affiliated  group of corporations  that files a consolidated
return for Federal income tax purposes.

                The schedules of casualty  Values,  special  Casualty Values and
Termination Values attached hereto shall be appropriately  adjusted in the event
of any adjustment to Basic Rent under this section 3(d).

                  (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 (i) in

consequence  of any  releveraqing  or  refunding of the Notes or the issuance of
Additional  Notes the  unpaid  principal  amount of Notes  Outstanding  shall be
greater  or  less  than  the  unpaid  principal  amount  of  Motes   Outstanding
immediately prior to such  transaction,  (ii) in consequence of events described
in clause  (i)  above,  the  schedule  of  amortization  of  principal  of Notes
Outstanding  after  such  transaction  shall  be  other  than  the  schedule  of
amortization of principal of Notes  immediately prior to such transaction or the
interest  rate  applicable  to such Notes shall be other than  contained  in the
Pricing  Assumptions,  (iii)  Transaction  Expenses  are paid by the  Lessor  in
amounts  greater or less than an amount equal to 0.8% of Facility  Cost, or (iv)
there is any change in the Pricing Assumptions.

                (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 made within 45 days
after the Owner  Participant  shall have  furnished  the revised  amounts to the
Lessee) by the Owner  Participant's  nationally  recognized  independent  public
accountants (to whom the Owner  Participant  shall have provided all information
necessary to perform such  verification),  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  calculations,  or (ii) if such
accountants shall for any reason be unable to provide such confirmation, compute
and  provide  to the  Lessee,  the  Lessor,  the  Owner  Participant,  the  Loan
Participant and the Indenture  Trustee revised amounts and percentages 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, and the

Owner  Participant.  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
differs by more than 10% from the amount 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 2 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 supplement 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  75-2a,  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 such Basic
Rent  Payment  Date on all Notes then  Outstanding,  and (ii)  unless the Lessee
shall have  assumed the Notes or  acquired  the Owner  Participant's  beneficial
interest  in the  Trust  following  the  grant  of a  security  interest  in the
Undivided  Interest and the Real Property  Interest,  in each case in accordance
with the  terms of the  Indenture,  each  payment  of  Casualty  Value,  Special
Casualty  Value and  Termination  Value shall in no event be less (when added to
all other amounts other than Excepted Payments required to be paid by the Lessee
under this  Facility  Lease in respect of any Event of Loss or Deemed Loss Event
or the termination of this Facility Lease) than an amount sufficient,  as of the
date of payment,  to pay in full all  principal  of, and  premium,  if any,  and
interest then due on all Notes Outstanding on and as of such date of payment.

                (h)  Rent  Differential.  Prior  to  the  Refunding  Date,  each
installment (if any) of Basic Rent shall be increased or decreased,  as the case
may be, by the Rent Differential.  For purposes hereof,  Rent Differential shall
mean,  as of any  Basic  Rent  Payment  Date,  the  difference  between  (i) the
aggregate  amount of interest due and payable on such Basic Rent Payment Date on
the Notes then Outstanding, and (ii) the aggregate amount of interest that would
have been due and payable on such Basic Rent  Payment Date on such Notes if such
Notes had at all times during the relevant period borne interest at a rate equal
to 10.5% per annum  (computed  on the basis of a 36O-day  year of twelve  30-day
months).  If, as of any Basic Rent Payment  Date,  (A) the amount  determined in
accordance  with  clause  (y) 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,

counterclaim,  suspension,  recoupement, reduction, rescission, 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

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

Lease,  any other  Transaction  Document  or any  Financing  Occurrence,  or any
doctrine of force majeure, impassability, 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

under  this  Facility  Lease,  any other  Transaction  Document,  any  Financing
Document or any ANPP  Project  Agreement,  including,  without  limitation,  the

or  PVNGS,  or any part  thereof  or 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  contained in section 6(a) hereof 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 flow have or which at any time  hereafter  may be conferred

Facility Lease or to effect or claim any diminution or reduction of Rent payable
by the Lessee  here-under,  including,  without  limitation,  the  provisions of
Arizona Revised Statutes  Section 33-343,  except in accordance with the express

terminated  in whole or in part by  operation  of law or  otherwise,  except  as
specifically provided herein, the Lessee nonetheless 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

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.

                SECTION 5. Return and Disposition.

                  (a) Return of the  Undivided  Interest  and the Real  Property
Interest. On the Lease Termination Date, the Lessee will surrender possession of

Owner  Participant)  to  the  effect  that  (A)  the  Lessee  has  obtained  all
Governmental Action and action under the ANPP Participation  Agreement necessary
to effect such  surrender by the Lessee and receipt of  possession by the Lessor

or prior to the Lease Termination Date), and the undivided Interest and the Real
Property  Interest  shall be free and clear of all Liens  (other than  Permitted
Liens  described in clauses (i), (iv), (v) (other than those arising by, through
or under the Lessee alone), (vi), (vii) (other than as aforesaid), (viii) (other
than as aforesaid),  (ix),  (x), (xi) and (xiii) of the definition of such term)
and in the condition and state of repair required by Section A. The Lessor shall
not abandon the Undivided  Interest.  In the event that on or prior to the Lease
Termination  Date there  shall have  occurred a default by any ANPP  Participant
(other than the Lessee) under the ANPP Participation  Agreement and such default
shall not have  been  cured by the  defaulting  ANPP  Participant,  then (i) the
Lessee agrees to indemnify and hold the Lessor (and each  successor,  assign and
transferee  thereof)  harmless  against any and all  obligations  under the ANPP
Participation Agreement with respect to contributions or payments required to be
made  thereby  as a  result  of such  default  and  (ii) the  Lessor  (and  each
successor, assign and transferee thereof) agrees to reimburse the Lessee for all
amounts paid by the Lessee  pursuant to the foregoing  clause (i) to the extent,
but  only  to the  extent,  that  the  Lessor  (or  such  successor,  assign  or
transferee)  shall  have  actually  received  proceeds  from  the  sale  of  the
Generation  Entitlement  Share of the defaulting ANPP Participant as a result of
the payment made by the Lessee pursuant to the foregoing clause (i), and, to the
extent the Lessor (or such successor,  assign or transferee) shall have received
such proceeds, the amount to be reimbursed to the Lessee pursuant to this clause
(ii) shall  include  interest at. the Prime Rate from the date of any payment by
the  Lessee   pursuant  to  the  foregoing   clause  (i)  through  the  date  of
reimbursement of such amount pursuant to this clause (ii).

renew or purchase as provided in Sections 12 and 13,  respectively,  then during
the last  thirty-six  months of the Lease Term, the Lessor will attempt to lease
or dispose of the Undivided Interest and the Real Property Interest.  The Lessee
will fully cooperate with the Lessor in connection with the Lessor's  efforts to

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.  The Lessor
agrees that it may not  exercise  the remedy  contained  in Section  16(a) (vii)
hereof as a result of the  failure of the Lessee to comply  with  Section  (5) a
hereof if the Lessor  shall have failed to Transfer the  Undivided  Interest and
the Real Property  Interest to a purchaser  (which shall not be the Lessee or an
Affiliate  of the Lessee)  that shall have (i)  submitted a bid on or before the
date on which such Event of Default  arose which is the  highest  bona fide cash
bid so submitted  and is in an amount not less than the fair market value of the
Undivided  Interest and the Real Property  Interest and (ii) tendered payment in
full to the Owner Participant prior to the date upon which payment by the Lessee
would otherwise be required from the Lessee under section 16(a) (vii).

                  SECTION 6. Warranty of the Lessor.

                (a) Quiet  Enjoyment.  The Lessor  warrants that until the Lease

not be interrupted by the Lessor or any Person claiming by, through or under the
Lessor, and their respective successors and assigns.

                (b)  Disclaimer of Other  Warranties.  The warranty set forth in
Section  6(a) is in lieu of all  other  warranties  of the  Lessor  or the Owner
Participant,  whether  written,  oral or implied,  with respect to this Facility

Participant, the Indenture Trustee, the Collateral Trust Trustee, the Lessor and
the Lessee,  execution by the Lessee of this Facility Lessee shall be conclusive
proof of the  compliance  of Unit 2 (including  any Capital  Improvement)  , the

(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,

the Lessor may have  against any vendor or  manufacturer  with respect to Unit 2
(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

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).

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

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 receipt by the Owner  Participant  under Section 5.2 of the
Indenture of the payments  specified in Section 9(c) or 9 (d) and payment by the
Lessee of all other 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

continuing,  if as a  consequence  of a Deemed  Loss Event,  a Special  Purchase
Event,  an exercise of the Cure Option or  otherwise,  the Lessee is required to
purchase the Undivided  Interest and the Real Property  Interest,  this Facility
Lease shall not be  terminated  nor shall the use or possession of the Undivided
Interest  or the Real  Property  Interest  be  transferred  by the Lessee to the
Lessor or to any other  Person  prior to the actual  purchase  of the  Undivided
Interest and the Real Property Interest by the Lessee.

                (g)  Application  of Payments  on an Event of Loss.  My payments
received at any time by the Lessor or the Lessee (other than insurance placed by

                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 bet'4een the Lessor and the Lessee,
                as their interests may appear.

Payments  received 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

destruction,  damage, loss, condemnation,  confiscation,  theft or seizure of or
requisition  of  title  to or  requisition  of use  of,  Unit  2 or  the  Common
Facilities,  or any part  thereof,  not  constituting  an Event of Loss shall be

such  payments  shall be  divided  between  the  Lessor  and the Lessee as their
interests may appear.

                  (i)  Disposition at rise of Event of Default.  Notwithstanding
the  foregoing  provisions  of this Section 9, if an 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 the Lessee  shall have cured any such Event of Default,  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 and of the Indenture.

                  (j)  Assumption  of  Notes;  Creation  of  Lien  on  Undivided
Interest.  In connection  with a declared Event of Loss, a declared  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 Outstanding Notes set forth in Section
3.9(b) of the Indenture, and (ii) the Lessor agrees that, if the Lessee fails to

Indenture,  not  later  than two  Business  Days  prior to the date on which the

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, 1987,  furnish to the Lessor and the Owner Participant (A) a report signed by

contained to the  contrary,  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

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 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 L4(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 aver the highest bona
tide 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

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,

Section 14, the obligations of the Lessee under the ANPP Participation Agreement
(except  as  therein  expressly  provided  in  section  15.10  thereof)  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 Lessee to obtain bids or  otherwise  take any action in
connection  with any such 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 (but only if such purchaser
has obtained all requisite Governmental Action in connection therewith)

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.

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

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

pursuant  to this  Section  14, the  obligations  of the  Lessee  under the ANPP
Participation  Agreement (except as therein expressly  provided in Section 15.10
thereof) and the  Assignment  and  Assumption  shall  continue in full force and
effect and shall not be impaired by reason of any such termination.

                SECTION 15. Events of Default.

                The term Event of Default,  wherever used herein, shall mean any
of the  following  events  (whatever  the reason  for such Event of Default  and
whether it shall be  voluntary or  involuntary,  or come about or be effected by
operation of law, or be pursuant to or in compliance  with any Applicable Law or

not exhaust the same or constitute a waiver of any other right provided  herein.

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

within one month  after the date of the  Lessee's  notice,  such value  shall be

purposes of this paragraph  (e), shall be determined on the assumption  that the
purchaser shall be required to pay the full amount of the  decommissioning  cost
of the  Undivided  Interest.  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

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  paragraph (a) and assumption by the Lessee of all the  obligations  and
liabilities  of the Owner Trustee under the Indenture and the Notes  pursuant to

amounts  required  to be paid by the  Lessee  pursuant  to  this  paragraph  (e)
(including interest, if any, thereon pursuant to Section 3(b) (iii)), the Lessor

the Lessor or the Owner  Participant  shall cure any default by the Lessee under
the ANPP  Participation  Agreement,  then (so  long as an Event of  Default  has
occurred  and is  continuing)  the  Lessor,  together  with  each  other  Person
contributing to such cure, shall be entitled (to the full extent  enforceable in
accordance with  Applicable Law and the ANPP Project  Agreements) to receive the
Generation  Entitlement  Share  of  the  Lessee  under  the  ANPP  Participation
Agreement (not limited to Unit 2), with each contributor to such cure to receive
a percentage of such Generation Entitlement Share equal to the percentage of the
cure contributed thereby.

                 SECTION 20. Additional Covenants.

                The Lessee  agrees to comply  with and to pay,  as  Supplemental
Rent,  all  amounts  payable  by it under the  provisions  of  Section 13 of the

         Owner  Trustee and the owner  Participant  from all real and  potential
         liability in respect of a Nuclear Incident so long as neither the Owner
         trustee or the Owner Participant is in actual possession and control of
         Unit 2 or the Undivided Interest, unless (in the opinion of independent

                  during the  Renewal  Term,  an amount  equal to one-half of an
                  amount  determined  by dividing  the  aggregate  amount of all

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

The Lessor  shall have all  rights,  powers and  remedies  provided  for in this
Facility  Lease,  at law, in equity or other-tie,  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  Excepted  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  nominal  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 Tax Law  other  than a change in  respect  of a minimum  tax;

not exceed the aggregate amount of such upward  adjustments.  Adjustments  under
this  paragraph  (d) shall be (1) made not more than once a year and (2) limited
in the aggregate to the extent necessary such that the aggregate amount of Basic
Rent  theretofore  and  thereafter  payable  throughout  the  Basic  Lease  Term

made  pursuant to Section  3(e)) shall not exceed by more than 4% the  aggregate
amount of Basic Rent which would have been  payable  throughout  the Basic Lease
Term (calculated as aforesaid) had no such adjustments been made.

                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 Section 3.(d) ; provided,  however,  that this sentence  shall not apply to
the initial transfer of the owner Participant's beneficial interest in the Trust
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  appropriately  adjusted  (upward or downward) to preserve Net Economic
Return  if  there  is (i)  any  Supplemental  Financing,  (ii)  the  payment  of
Transaction Expenses in an amount which is other than 1.5% of the Purchase Price
or (iii) any other change (other than a change in items 4, 5, a (as to the basis
for amortization of Transaction  Expenses),  14, 15 and 17, but without limiting
the effect of Section 3(d) hereof) in the Pricing Assumptions.

                (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 within 90 days after
the Owner  Participant  furnishes  the revised  amounts to the Lessee,  the Loan
Participant,  the Lessor and the Indenture  Trustee) 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 or' a basis consistent with the original 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 arid percentages
originally provided by the owner Participant which differs by more than 10% from
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 supplement
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  Rant  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 all 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,  other than Excepted Payments,  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 all principal of, and premium, if any, and interest then
due on all Notes  outstanding  on and as of such date of  payment  (taking  into
account any assumption of the Notes by the Lessee).

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

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

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

shall become a security agreement for all purposes of Applicable Law. The Lessee
agrees to use its best  efforts to comply  with the  conditions  respecting  its
assumption  set forth in  Section  3.9(b) of the  Indenture  and,  failing  such
assumption,  agrees to accept a transfer of the owner Participant's right, title

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 or law which renders
any provision hereof prohibited or unenforceable in any respect.

                  (d) True  Lease.  This  Facility  Lease  shall  constitute  an

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

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  nominal  date

                  (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

not exceed the aggregate amount of such upward  adjustments.  Adjustments  under
this  paragraph  (d) shall be (1) made not more than once a year and (2) limited
in the aggregate to the extent necessary such that the aggregate amount of Basic
Rent  theretofore  and  thereafter  payable  throughout  the  Basic  Lease  Term

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 Section 3 (d); provided, however, that this sentence shall not apply to the
initial transfer of the Owner Participant's  beneficial interest in the Trust to
one of its Affiliates.

                (e)  Further  Adjustments.  Basic  Rent  and  the  schedules  of
Casualty Values,  Special Casualty Values and Termination Values attached hereto

                  (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 Lessee9s  request within 90 days after
the Owner  Participant  furnishes  the revised  amounts to the Lessee,  the Loan
Participant,  the Lessor and the Indenture  Trustee) 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  calculations,  or
(ii) compute and provide to the Lessee, the Lessor,  the Owner Participant,  the

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 differs by more than 10% from
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 supplement
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  oadjustment
otherwise required pursuant to this Section 3.

                  (g)  sufficiency  of  Basic  Rent  arid   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 all 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,  other than Excepted Payments,  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 all principal of, and premium, if any, and interest then
due on all Notes  Outstanding  on and as of such date of  payment  (taking  into
account any assumption of the Notes by the Lessee).

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

be binding on the Lessor if, on the effective date thereof,  an Event of Default

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

                  ending on the day 90 days after  such last Basic Rent  Payment
                  Date,  to find a Person  willing  to  submit  such  cash  bid;
                  provided,  however,  that the  failure  of the Lessor to do so
                  shall not  relieve  the Lessee of its  obligations  under this
                  clause (vii)).

                    (b)  No  Release.  No  rescission  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;  provided,   however,  that
notwithstanding  anything to the contrary set forth in this Facility Lease,  the
remedy set forth in section 16(a) (vii) shall be the sole and  exclusive  remedy
under this  Section 16 in the case of an Event of  Default  specified  in clause
(iv) of Section 15,  unless the Lessee is in default of its payment  obligations
under  Section  16(a)  (vii),  in which case the Lessor may  exercise  its other
remedies  under Section  16(a);  (except that the maximum  amount payable by the
Lessee  in the  event  of the  exercise  by the  Lessor  of any of the  remedies
provided  for in Section  16 (a) (v) or (vi)  shall not exceed the total  amount
payable by the Lessee  under  Section  16(a) (vii) minus the amount  provided in
subclause  (2) of  clause  (A),  (S) or (C) of such  Section  16(a) (v) , if the

Lessor  elects  a  remedy  specified  in said  clause  (A) , (S) or (C) , or the
deficiency  referred to in Section  16(a)(vi),  if the Lessor  elects the remedy
specified in section 16 (a) (vi)  hereof) . 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 2 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, except to
the extent  expressly  limited by  provisions  of this Section 16,  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(iii),  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  due 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 indenture1 the Lessor shall (so long as
no Default or Event of Default shall have occurred and be  continuing)  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 the Owner  Participant shall have received under Section 5.2
of the indenture all amounts  required to be paid by the Lessee pursuant to this
paragraph  (e)  (including  interest,   if  any,  thereon  pursuant  to  Section
3(b)(iii)), 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
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 then  Outstanding  and this  Facility  Lease
shall become a security agreement for all purposes of Applicable Law. The Lessee
agrees to use its best  efforts to comply  with the  conditions  respecting  its
assumption  set forth in Section  3.9(b) of the  'Indenture  and,  failing  such
assumption,  agrees to accept a transfer of the Owner Participant's right, title
and  interest  in  the  Trust  Estate  pursuant  to  Section  7(b)  (4)  of  the
Participation Agreement.

                  SECTION 17.  Notices.

                  All  communications  and notices provided for in this Facility
Lease shall be in writing and shall be given in person (with  signed  receipt of
an  officer  of the Owner  Participant  in the case of a  delivery  to the Owner
Participant)  or by means of telex,  telecopy,  or other wire  transmission,  or

service,  addressed  as  provided  in  the  Participation  Agreement.  All  such
communications  and notices  given in such manner shall be effective on the date

                  SECTION l8.  Successors and Assigns.

                  This  Facility  Lease,  including all  agreements,  covenants,
indemnities,  representations and warranties, shall be binding upon and inure to
the benefit of the Lessor and its  successors  and  permitted  assigns,  and the
Lessee and its successors and, to the extent permitted hereby, assigns.

                  SECTION 19.  Right to Perform for Lessee.

                  If the  Lessee  shall  fail to make any  payment of Rent to be
made by it, or shall fail to perform or comply with any of its other  agreements
contained  herein,  or fail to make any  payment to be made by it under any ANPP
Project  Agreement,  or shall fail to  perform  or comply  with any of its other
agreements  contained in any ANPP  Project  Agreement,  either the Lessor or the
Owner  Participant  may, but shall not be obligated to, tender such payment,  or
effect such  performance or  compliance,  and the amount of such payment and the
amount of all costs and expenses (including, without limitation,  attorneys' and
other  professionals' fees and expenses) of the Lessor or the Owned Participant,
as the case may be,  incurred in connection with such payment or the performance
of or compliance with such agreement, as the case may be, together with interest
thereon at the Penalty Rate, shall be deemed  Supplemental  Rent, payable by the
Lessee upon demand.  In the event that the Lessor or the Owner Participant shall
cure any default by the Lessee under the ANPP Participation Agreement,  then (so
long as an Event of Default has occurred and is continuing) the Lessor, together
with each other Person contributing to such cure, shall be entitled (to the full
extent  enforceable in accordance with Applicable Law) to receive the Generation
Entitlement  Share of the Lessee  under the ANPP  Participation  Agreement  (not
limited  to Unit 2),  with each  contributor  to  receive a  percentage  of such
Generation  Entitlement  Share equal to the  percentage of  the cure contributed
thereby.

Participation  Agreement  and under the  provisions  of the Tax  Indemnification
Agreement,  which provisions are incorporated  herein by this reference as fully
as if set forth in full at this  place.  The  Lessee  agrees to comply  with its
covenants  and  agreements  set  forth  in  Sections  10(b),  14  and  16 or the
Participation  Agreement  and Articles III, IV, V and VI of the  Assignment  and

                  Pursuant  to  the  Deed  and  the   Assignment  of  Beneficial
Interest,  the Lessee has sold to the Lessor  the Real  Property  Interest.  The
Lessor  hereby  grants to the Lessee a leasehold  interest in the Real  Property
interest,  such  leasehold  to be  coterminous  with the lease of the  Undivided

any  applicable  statute of  limitations  by the Owner  Trustee,  the  Indenture
Trustee,  the  Lessee,  the  Owner  Participant,  the  Loan  Participant  or any
Indemnitee  shall not affect such survival.  The obligations of the Lessee under

unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  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  elsewhere  shall be  construed  as
conveying  to the Lessee any right,  title or  interest  in or to the  Undivided
Interest or the Real Property Interest, except as lessee only.

         This  Agreement  does not  extend to a release of the  Company  for any
benefits  payable  pursuant to the Agreement,  nor to any benefits that Employee

to any claims or rights under the federal Age  Discrimination  in Employment Act
which may arise out of the actions of the Company or an Affiliate after the date
of this  Agreement.  Notwithstanding  anything  herein to the contrary,  nothing
herein  shall be  construed  as to  abrogate  or  supersede  any  obligation  or
agreement of the Company or Affiliates that may exist outside of this Agreement,
pursuant  to  applicable  bylaw  provisions  of the  Company or  Affiliates,  to
indemnify  Employee,  or to provide Employee with director and officer liability
insurance. This Agreement shall not increase or adversely impact any such rights
or obligations to which Employee may be entitled under such  indemnification  or
directors  and  officers  liability  insurance  referred  to in the  immediately
preceding sentence.

         (b) No Release of Employee.  The Company and  Affiliates do not release
Employee  from any  claim  which the  Company  or an  Affiliate  has or may have
against Employee arising out of or relating to Employee's  relationship,  in any
capacity,  with the Company or Affiliates.  This Agreement also does not release
Employee for expressly  contracted debts or loans due the Company or Affiliates,
evidenced  by  written  notes  or   agreements,   or  for  willful,   wanton  or
intentionally wrongful acts, nor does this Agreement extend to matters or events
occurring after the date of this Agreement.

         5.       Confidential Information.

         (a) Employee Acquired Confidential  Information.  Except as required by
law,  Employee agrees to keep  confidential all  "Confidential  Information" (as
defined in this  Agreement)  obtained  during the course of employment  with the
Company and the positions she has held with Affiliates. Employee agrees that she
will not reveal any Confidential Information to any other person, corporation or
entity,   without  the  prior  written   consent  from  an  authorized   Company
representative.  The term  "Confidential  Information" as used in this Agreement
means  information,  written or  otherwise,  which  Employee has received in the
course of her  relationship,  in any capacity with the Company or Affiliates and
includes,  without  limitation,  all  reports,  forecasts,  contracts,  customer
information,   confidential  commercial  information,  trade  secrets,  business
secrets,  personnel  information or any information that is not available to the
general public.  Any  information,  analysis or  interpretation  which is public
information as a result of (A) a public filing made by the Company or Affiliates
or (B)  information  supplied  by the Company or  Affiliates  pursuant to formal
discovery  procedures  (unless such  information,  analysis or interpretation is
public  as a result  of a breach  of this  Agreement)  shall  not be  considered
Confidential Information.

         (b) Confidential Employment Information. PNM and Affiliates agree that,
consistent with current policy,  they will only release  information  confirming
dates of employment and positions held by Employee.

         (c) This Agreement  Confidential.  The parties, and each of them, agree
that this Agreement has been entered into with the understanding that all of the
terms and  conditions  hereof  will remain  confidential  and that they or their
legal representatives will not, except as provided herein, disclose to any Third
Party the terms and conditions of this  Agreement  unless the other party hereto
consents in writing to such disclosure.  As used herein, "Third Party" means any
person, corporation,  partnership,  firm, consultant, or governmental entity, or
representatives  of any of the  foregoing,  other than  officers,  employees and
attorneys of the parties to this Agreement.

                                       4

         (d)  Protective  Order.  In the event that  Employee  is  requested  or
required to disclose the Confidential  Information pursuant to Section 5(a), (b)
or (c) above,  it is agreed that Employee  shall provide the Company with prompt
written  notice of such  request(s)  at least ten (10) days  prior to making any
such  disclosure  and  advise  whether  or  not  Employee  intends  to  seek  an
appropriate  protective  order to preclude  disclosure of such  information.  If
Employee seeks a protective order, the Company or any Affiliate may join in such
action.  If Employee  does not seek a protective  order,  then the Company or an
Affiliate shall have such right to seek a protective  order.  The parties to the
Agreement  agree to cooperate in seeking a protective  order if any party hereto
so requests.

         If Employee  seeks such  protective  order,  without the Company or the
Affiliate joining such action, or if the Company and/or the Affiliate  commences
such action,  without Employee seeking or joining in such action, then the party
seeking  such  protective  order  shall  pay  the  attorney  fees  and  expenses
associated  therewith,  including the reasonable  attorney fees and costs of any
other party to this  Agreement who requires such legal counsel to protect her or
its  interest  pursuant to such  action.  If  Employee  or the  Company  (and/or
Affiliate)  both join in such action,  then each shall be responsible for her or
its respective attorney fees and costs. If, in the absence of a protective order
or the receipt of a waiver  hereunder,  a party is legally bound, in the written
opinion of its counsel, to disclose the Confidential Information, it may legally
do so without a breach of this  Agreement.  PNM and  Affiliates  shall  instruct
their  directors,  officers,  employees,  agents and  attorneys  to maintain the
confidentiality  provisions hereof.  Notwithstanding the foregoing,  all parties
hereby consent to the disclosure of information  contained in or related to this
Agreement to the extent  required,  in the opinion of counsel to a party hereto,
to  comply  with  applicable  securities  laws and  regulations  or the laws and
regulations administered by the NMPUC which bind such party.

         6. Agreement to Assist  Company.  Employee agrees to assist the Company
when requested from time to time in the future,  such as in providing  testimony
or providing information to the Company or its counsel.

         7.  Accord and  Satisfaction.  Employee  agrees that the  payments  and
benefits  provided for pursuant to this  Agreement and the  provisions  included
hereunder  constitute full settlement and satisfaction of all claims released by
Employee as described in Section  4(a),  and agrees that this  Agreement and the
benefits  provided  pursuant to this  Agreement  are not to be  construed  as an
admission of liability by the Company, Affiliates, or their directors, officers,
supervisors,  agents, employees or any other persons or entities being released.
Employee  further agrees that  acceptance of the payments and benefits  provided
under this  Agreement  constitute  a waiver of all rights  Employee  may have to
pursue any rights and  privileges  under any  internal  grievance  procedure  or
policy.

                                       5

other  benefits to which  Employee  may be eligible  under (i)  severance  plans

Affiliates  thereof  (including  any  right  to  receive  a notice  of  position
impaction  under Company or Affiliates  severance  plans,  which right is hereby
specifically waived), (ii) executive or employee retention plans or similar type
change in control  plans or  agreements  maintained  by  Company  or  Affiliates
thereof,  or (iii) any other benefit plan of the Company or its  Affiliates  not

provided  hereunder are  contingent  upon the Employee  properly  completing and
delivering  this Agreement  without  revoking the same as otherwise  provided in
Section 4 hereof.

         14.  Signature by Employee.  Employee has twenty-one (21) days from the

Following  the signing of the  Agreement by  Employee,  she shall have seven (7)
days to revoke the same by  returning  a revoked  copy of the  Agreement  to the
Company.  The date of the signature and delivery by Employee shall be determined
by the date set  forth  in the  notarial  acknowledgment  with  respect  to such
signature.

         EMPLOYEE HAS CAREFULLY READ AND FULLY UNDERSTANDS ALL OF THE PROVISIONS

         Document to which it (in any capacity) is, or is to become on or before
         the Closing Date, a party,  nor the  performance in such capacity by it
         of its  obligations  hereunder  or  thereunder,  will subject the Trust
         Estate or the Lease Indenture  Estate,  or any portion thereof,  to any
         Owner Trustee's Lien.

The representations and warranties in Section 8(a)(2) and Section 8(a)(2), as to
Transaction Documents and the Initial Series Mote being legal, valid and binding
obligations  enforceable in accordance with their  respective  terms,  are given

        and the Indenture  without the prior written consent of the Lessee.  FNB
        agrees that except for amendments or supplements,  if any, made pursuant
        to Article x of the Trust Agreement or contemplated by Section  7(b)(4),
        FNB will not amend or  supplement,  or  consent to any  amendment  of or
        supplement to, the Trust  Agreement if such amendment  would  materially
        and adversely  affect the rights of the Lessee under the Facility  Lease
        and this Participation  Agreement,  without the prior written consent of
        the Lessee  unless a Default or an Event of Default has  occurred and is
        continuing or the Lease Termination Date has occurred.

        payment in full of the Bonds and the  discharge in  accordance  with its
        terms of the Collateral Trust Indenture, FNB (in all capacities) agrees
        that it will not file a  petition,  or join in the filing of a petition,
        seeking reorganization,  arrangement, adjustment or composition of or in
        respect of the Loan  Participant  under the Bankruptcy Code or any other
        applicable Federal or state law or the law of the District of Columbia

         to the property, rights, titles and interests of the Lessee transferred
         to the Lessor pursuant to the Transaction Documents; provided, however,
         that the foregoing  shall not limit in any way the effect of Section 15
         or 16 of the Facility  Lease or any  liability or  obligation  that the
         Lessee may incur to the Owner  Trustee or the Owner  Participant  under
         any  Transaction  Document  as a  result  thereof  (including,  without
         limitation,  any  liability  that PNM may incur under Section 16 of the
         Facility Lease as the result of an Event of Default).

                (3) Cash Bids.  Upon the  expiration  of the Facility  Lease and
        upon the Lessee  failing to  purchase  or  otherwise  reacquire  all the
        right,  title and  interest  in PVNGS  and  contractual  rights  related
        thereto  necessary  for the  operation  of the  interest  (the  Lessor's
        Interest) acquired by the Lessor pursuant to the Transaction  Documents,
        the Lessor shall entertain cash bids from each ANPP  Participant for the
        Lessor's Interest.

                (4) Survival.  The provisions of this paragraph (4) and Sections
        8(c)(1),  (2) and (3) shall  remain in full force and effect  until such
        time as the ANPP Administrative Committee or the ANPP Participants shall
        otherwise consent.

                (5) License Matters.  The Owner Trustee acknowledges that before
        taking  possession of the  Undivided  Interest or any part thereof or of
        any other  interest in PVNGS,  either of the  following may be required:
        (i) the  issuance of an  appropriate  license  from the NRC,  whether by
        amendment to the License or otherwise, or (ii) a partial transfer of the
        License  authorizing the Lessor to possess its interest in PVNGS, to the
        extent of the undivided Interest,  upon application for partial transfer
        of such License to such extent filed pursuant to Applicable Law. Neither
        the  Owner   Trustee   nor  the  Owner   Participant   shall   have  any
        responsibility whatsoever to take or initiate any action with respect to
        any NRC licensing matter.

                  (18) No Default,  etc.  The Lessee is not in  default,  and no
         condition  exists  that,  with the giving of notice or lapse of time or
         both,  would  constitute  a default by the Lessee,  under any  material
         mortgage, deed of trust, indenture, lease, contract or other instrument
         or  agreement  to which the  Lessee is a party or by which it or any of
         its properties or assets may be bound.

                (19)  Certain  Documents.  True and  correct  copies of the ANPP
        Participation   Agreement,  the  Material  Project  Agreements  and  the
        Existing Mortgage have been delivered to the Owner Participant's Special
        Counsel for and on behalf of the Owner  Participant prior to the date of
        execution  hereof.  No ANPP  Project  Agreement  will,  on and after the
        closing Date,  materially and adversely interfere with ( i ) (except for
        the  AMP?  Participation   Agreement  in  the  case  of  the  Generation
        Entitlement  Share only) the title of the Owner Trustee to the Undivided
        Interest,  the related Generation Entitlement Share or the Real Property
        Interest or (ii) except for the ANPP  Participation  Agreement,  the use
        of,  or the  exercise  by the  Owner  Trustee  of its  rights  under the
        Facility Lease, the Deed, the Assignment of Beneficial  Interest and the
        Assignment and Assumption with respect to, the Undivided  Interest,  the
        related  Generation  Entitlement  Share,  and the interests in the PVNGS
        Site  (including  the Real Property  Interest)  granted or to be granted
        under the Deed, the Assignment of Beneficial Interest and the Assignment
        and Assumption. No payment default or other default of a material nature
        by the Lessee has occurred and is continuing under the Existing Mortgage
        or any ANPP Project Agreement. The AMPP Participation Agreement and each
        other ANPP Project  Agreement are in full force and effect and no breach
        of any thereof,  to the Lessee's  knowledge,  by any other party thereto
        has occurred and is continuing,  except where the failure to be in force
        and effect or such breach would not have a material  and adverse  effect
        on the Undivided Interest, the related Generation Entitlement Share, the
        Real Property Interest, Unit 1 or the rights,  interests and benefits of
        the  Owner  Trustee  or the  Owner  Participant  under  any  Transaction

         Document.  Upon execution and delivery of the Mortgage  Release and the
         recordation  thereof or of UCC  releases  in respect  thereof,  (i) the
         mortgagee and secured party  thereunder  will have released the lien of
         the Existing Mortgage on the Undivided Interest, the related Generation
         Entitlement Share and the Real Property Interest and (ii) the rights of
         the Owner  Trustee  in the  Undivided  Interest  and the Real  Property
         Interest and the related Generation  Entitlement Share will not be, and
         will not become,  subject or  subordinate  to the rights of any Person,
         except  the  Indenture   Trustee  under  the  Indenture  and  the  ANPP
         Participants   to  the   extent   expressly   set  forth  in  the  ANPP
         Participation  Agreement  (as in effect on the Closing Date) and except
         as may otherwise expressly be permitted by the Facility Lease. The lien
         of the  Existing  Mortgage  does not  extend  to  rights  of PNM  under
         Transaction Documents (other than the Lessee's leasehold interest under
         the Facility Lease) or to the Generation  Entitlement  Share related to
         the  Undivided   Interest.   Neither  Section   15.6.3.5  of  the  ANPP
         Participation  Agreement  nor  Section  8(c)(3)  of this  Participation
         Agreement  (i)  requires  the  Owner  Trustee  to  accept  any cash bid
         referred  to therein or (ii)  otherwise  materially  impedes  the Owner
         Trustee's right,  upon a failure by the Lessee to purchase or otherwise
         reacquire the Undivided  Interest and the Real  Property  Interest,  to
         conclude a sale or lease to a Person  constituting a "Transferee" under
         Section 15.10 of the ANPP Participation Agreement

                  (20) Unit 1. The  description of unit 1 set forth in Exhibit B
         to the Bill of Sale is correct  and  sufficiently  complete to identify
         such property.

                  (21)  Investment  Company Act. The Lessee is not, and will not
         become1  an  "investment  company  or  a  company  "controlled"  by  an
         "investment company", within the meaning of the Investment Company Act.

                (b)     Agreements of Lessee.

Lease, except to the extent expressly provided in any Transaction Document,  the
ANPP  Participation  Agreement  or any other  agreement  or  undertaking  of the
Lessee,  (2) for any Claim against such  Indemnitee  resulting  solely from acts

of remedies under Section 16  thereof or the  transfer  contemplated  by Section
7(b)(4) or the first  transfer by the Owner  Participant  to an Affiliate of the
Owner   Participant.   To  the  extent  that  an  Indemnitee  in  fact  receives
indemnification payments from the Lessee under the indemnification provisions of
this  Section  13(a),  the  Lessee  shall be  subrogated,  to the extent of such
indemnity paid, to such  Indemnitee's  rights with respect to the transaction or
event  requiring  or  giving  rise to such  indemnity,  but only so long as such
subrogation shall not materially  adversely affect the rights of such Indemnitee
or any other Indemnitee  hereunder.  Nothing herein contained shall be construed
as constituting a guaranty by the Lessee of the principal of or premium, if any,
or interest on the Notes or the Bonds or of the residual value or useful life of
the undivided Interest.

        (b)      General Tax Indemnity.

        (1)  Indemnity.  All  payments  by the  Lessee  in  connection  with the
        transactions  contemplated by the Transaction Documents shall be free of
        withholdings  of any nature  whatsoever (and at the time that the Lessee
        is required to make any payment upon which any  withholding is required,
        the  Lessee  shall pay an  additional  amount  such that :he net  amount
        actually  received by the Person  entitled to receive such payment will,
        after such  withholding,  equal the full amount of the payment then due)
        and shall be free of expense to each  Indemnitee for collection or other
        charges.  If, for any reason, the Lessee is required to make any payment
        to a  taxing  authority  with  respect  to,  or  as  a  result  of,  any
        withholding tax imposed on any Indemnitee in respect of the transactions
        contemplated  by the  Transaction  Documents by reason of the Indemnitee
        not being a united States person,  then such Indemnitee shall pay to the
        Lessee on an  After-Tax-Basis  an amount which equals the amount paid by
        the  Lessee  with  respect  to or as a result of such  withholding  tax.
        whether  or  not  any  of  the  transactions   contemplated  hereby  are
        consummated,  except as provided in Section  13(b)(2),  the Lessee shall
        pay, and shall indemnify,  defend and hold each Indemnitee harmless,  on

                 resulting  from the gross  negligence or willful  misconduct of
                 such  Indemnitee  (it being  understood  that no  Indemnitee is
                 responsible  for  determining  whether a Tax is  payable if the
                 Lessee is required to  indemnify  the  Indemnitee  for such Tax

        Lessee,  but  not  before  the  Lessee  shall  have  made  all  payments
        theretofore  due to such  Indemnitee  pursuant to this Section 13(b), an
        amount  equal to the lesser of (x) the sum of such tax benefit  plus any
        other net tax benefit  realized by such  Indemnitee as the result of any
        payment made by such Indemnitee pursuant to this sentence (determined in
        a manner consistent with the definition of After-Tax-Basis  set forth in
        Appendix A and with the last  sentence  of section 13 (b)(6)  hereof) or
        (y) the amount of such payment by the Lessee to such  Indemnitee and any
        other payment by the Lessee to such Indemnitee theretofore made pursuant

        such  Indemnitee to the Lessee  pursuant to this clause (y) with respect
        to amounts paid pursuant to section 13(b) (1), it being intended that no
        Indemnitee  should  realize a net tax benefit  pursuant to this  Section
        13(b)  unless  the  Lessee  shall  first  have been  made  whole for any
        payments  by it to  such  Indemnitee  pursuant  to this  Section  13(b);
        provided,  however,  that in computing any  permanent tax benefit,  such
        Indemnitee  shall be deemed first to have  utilized all  deductions  and

         credits  available to it otherwise than by reason of any payment by the
         Lessee pursuant to this Section 13(b); provided further,  however, that
         notwithstanding  the  provisions  of this clause (3),  such  Indemnitee
         shall not be  obligated  to make any payment to the Lessee  pursuant to
         this  clause (3) if at the time such  payment  shall be due an Event of
         Default shall have occurred and be continuing.

        (4) General  Tax  Indemnity-Contests.  If a written  claim shall be made
        against  any  Indemnitee  for any Tax for which the Lessee is  obligated
        pursuant to this Section 13(b),  such Indemnitee shall notify the Lessee
        promptly of such claim but the failure so to notify the Lessee shall not
        affect any obligation of the Lessee  pursuant to this Section 13(b).  If
        the Lessee  shall  reasonably  request  in writing  within 30 days after
        receipt of such notice,  such Indemnitee  shall in good faith and at the
        Lessee's  expense  contest  the  imposition  of  such  Taxes;  provided,
        however,  that such  Indemnitee  may in its sole  discretion  select the
        forum for such contest and  determine  whether any such contest shall be
        by (A)  resisting  payment of such  Taxes,  (B) paying  such Taxes under
        protest or (C) paying such Taxes and seeking a refund thereof;  provided
        further,  however,  that (W) such  Indemnitee  shall not be obligated to
        contest any claim in which the amount in question is less than $250,000,
        (X) at such Indemnitee's  option, such contest shall be conducted by the
        Lessee in the name of such Indemnitee (subject to the preceding proviso)
        and (Y) in no event  shall such  Indemnitee  be  required  or the Lessee
        permitted to contest the imposition of any Taxes for which the Lessee is
        obligated  pursuant to this  Section  13(b)  unless (u) the Lessee shall
        have  acknowledged  its  liability to such  Indemnitee  for an indemnity
        payment  pursuant to this Section 13(b) as a result of such claim if and
        to the extent such  Indemnitee or the Lessee,  as the case may be, shall
        not prevail in the contest of such claim; (v) such Indemnitee shall have
        received from the Lessee (i)  satisfactory  indemnity for any liability,
        expense or loss  arising out of or relating to such  contest  including,
        but not limited to, (A) all reasonable legal, accountants' and

       investigatory  fees and  disbursements,  (B) the amount of any  interest,
       additions  to  tax or  penalties  that  may be  payable  as a  result  of
       contesting  such claim and (C.) if such contest is to be initiated by the
       payment of, and the claiming of a refund for such Tax,  sufficient  funds
       to make  such  payment  on an  After-Tax-Basis  and  (ii) an  opinion  of
       independent  tax  counsel  selected  by the Lessee and  approved  by such
       Indemnitee  (which  approval  shall  not be  unreasonably  withheld)  and
       furnished  at the  Lessee's  sole expense to the effect that a Reasonable
       Basis  exists  for  contesting  such claim or, in the event of an appeal,
       that there exists a substantial possibility that an appellate court or an
       administrative  agency with appellate  jurisdiction,  as the case may be,
       will reverse or substantially  modify the adverse  determination that the
       Lessee  desires to contest;  (w) the Lessee shall have agreed to pay such
       Indemnitee on demand, and on an After-Tax-Basis, all reasonable costs and
       expenses that such  Indemnitee  may incur in connection  with  contesting
       such claim (including,  without limitation,  all costs, expenses, losses,
       reasonable legal and accounting fees, disbursements,  penalties, interest
       and  additions  to  tax);  (x)  such  Indemnitee  shall  have  reasonably
       determined  that the  action to be taken will not result in any danger of
       sale,  forfeiture  or loss of, or the creation of any Lien (except if the
       Lessee shall have adequately bonded such Lien or otherwise made provision
       to protect the interests of such  Indemnitee in a manner  satisfactory to
       such  Indemnitee) on, Unit 1, any part thereof,  the Undivided  Interest,
       the Real Property Interest, or any interest in any of the foregoing;  and
       (y) if such contest shall be conducted in a manner  requiring the payment
       of the claim, the Lessee shall have paid the amount required.  The Lessee
       agrees to give such Indemnitee  reasonable notice of any contest prior to
       the commencement thereof. If any Indemnitee shall obtain a refund of. all
       or any part of any Taxes paid by the Lessee,  or if any such refund would
       be payable to the  Indemnitee in the absence of an  offsetting  liability
       for Taxes payable to the taxing  authority in question,  such  Indemnitee
       shall pay the Lessee, but not before the Lessee

       shall have made all payments  theretofore due to such Indemnitee pursuant
       to this Section  13(b),  an amount equal to the lesser of (xx) the amount
       of such refund so received or receivable,  including interest received or
       receivable and attributable  thereto,  plus any net permanent tax benefit
       realized by such Indemnitee  (determined in a manner  consistent with the
       definition of  After-Tax-Basis  set forth in Appendix A and with the last
       sentence of Section  13(b)(E)  hereof) as a result of any payment by such
       Indemnitee  made  pursuant to this  sentence (but only to the extent that
       such net  permanent  tax benefit was not taken into  account  pursuant to
       Section 13(b)(3)),  and after taking into account the tax consequences of
       the receipt of such refund and such interest) or (yy) such tax payment by
       the  Lessee to such  Indemnitee  plus any other  payment by the Lessee to
       such  Indemnitee  theretofore  made  pursuant to this Section  13(b),  in
       either  case,  net of any  expenses  not already  paid or incurred by the
       Lessee;  provided,  however,  that in  computing  any net  permanent  tax
       benefit,  such  Indemnitee  shall be deemed  first to have  utilized  all
       deductions  and credits  available to it otherwise  than by reason of any
       payment by the Lessee pursuant. to this Section 13(b)1 provided, further,
       however,  that  not-withstanding  the provisions of this clause (4), such
       Indemnitee  shall not be  obligated  to make any  payment  to the  Lessee
       pursuant  to this clause (4) if at the time such  payment  shall be due a
       Default or an Event of  Default  shall have  occurred  and be  continuing
       under the Facility Lease. An Indemnitee shall not be required to make any
       payment  pursuant to this clause (4) before such time as the Lessee shall
       have made all payments  and  indemnities  then due under the  Transaction
       Documents to such Indemnitee.  Notwithstanding anything contained in this
       clause (4) to the contrary,  no  Indemnitee  shall be required to contest
       any claim if the subject matter  thereof shall be of a continuing  nature
       and shall have previously been decided pursuant to the contest provisions
       of this  clause  (4)  unless  there  shall  have been a change in the law
       (including,  without  limitation,  amendments to statutes or regulations,
       administrative rulings and court decisions) after

       such claim shall have been so  previously  decided,  and such  Indemnitee
       shall have received an opinion of independent tax counsel selected by the
       Lessee and  approved  by such  Indemnitee  (which  approval  shall not be
       unreasonably  withheld) and furnished at the Lessee's sole expense to the
       effect  that such change  provides a  Reasonable  Basis for the  position
       which such Indemnitee and the Lessee, as the case may be, had asserted in
       such  previous  contest or for an  alternative  position  based upon such
       change that the Lessee now desires to assert.  Nothing  contained in this
       section  13(b)  shall  require  any  Indemnitee  to contest or permit the
       Lessee to contest a claim which it would otherwise be required to contest
       pursuant to this Section 13(b) if such Indemnitee  shall waive payment by
       the Lessee of any amount  that might  otherwise  be payable by the Lessee
       under this Section 13(b) by way of indemnity in respect of such claim. If
       Lessee  4oes  not  request  that  a Tax be  contested  pursuant  to  this
       paragraph (5),  Lessee shall pay the Indemnitee  therefor unless such Tax
       was not included in the  indemnification  under  Section 13 (b)(l) or was
       excluded by Section 13 (b) (2).

        (5) General Tax Indemnity-Reports. If any report, return or statement is
        required to be filed with respect to any obligations of the Lessee under
        or arising out of this Section 13(b), the Lessee shall timely notify the
        Indemnitee and timely file the same, except for any such report,  return
        or  statement  which such  Indemnitee  has  notified  the Lessee that it
        intends to file.  The Lessee shall  either file such  report,  return or
        statement so as to show the ownership of the  undivided  Interest or the
        Real  Property  Interest,  as the case may be, in the Owner  Trustee and
        send a copy of such report, return or statement to the Owner Trustee and
        such Indemnitee or, where not so permitted, notify the Owner Trustee and
        such Indemnitee of such requirement and prepare and deliver such report,
        return or statement to the Owner Trustee and such Indemnitee in a manner

         reasonable  time prior to the time such report,  return or statement is
         to be filed  or,  where  such  return,  statement  or  report  shall be
         required to reflect items in addition to any  obligations of the Lessee
         under or arising out of this Section  13(b),  provide the Owner Trustee
         and such Indemnitee with information  sufficient to permit such return,
         statement or report properly to be made with respect to any obligations
         of the  Lessee  under or  arising  out of this  Section  13(b) (and the
         Lessee  shall  hold  each  Indemnitee  harmless  from and  against  any
         liabilities,  obligations, losses, damages, penalties, claims, actions,
         suits  and  reasonable  costs  arising  out  of  any  insufficiency  or
         inaccuracy in any such return,  statement report or  information).  The
         Lessee  shall  not have any right to  examine  the tax  returns  of any
         Indemnitee.

        (6)       General Tax Indemnity-Payment. All Taxes
        shall be paid when due and payable and,  unless  otherwise  requested by
        the appropriate Indemnitee,  the Lessee shall pay any Taxes for which it
        is liable  pursuant to this Section  13(b)  directly to the  appropriate
        taxing authority and shall pay such appropriate  Indemnitee  promptly on
        demand in  immediately  available  funds any amount due such  Indemnitee
        pursuant to this  Section  13(b) with  respect to such  Taxes.  Any such
        demand shall specify in reasonable detail the payment and the facts upon
        which the right to  payment is based.  Each  Indemnitee  shall  promptly
        forward  to the  Lessee  any  notice,  bill  or  advice  received  by it
        concerning  any Taxes.  Within 30 days after the date of each payment by
        the  Lessee of any Taxes,  the  Lessee  shall  furnish  the  appropriate
        Indemnitee  the  original  or a  certified  copy  of a  receipt  for the
        Lessee's payment of such Taxes or such other evidence of payment of such
        Taxes as is acceptable to such Indemnitee. The Lessee shall also furnish
        promptly upon request such data as any  Indemnitee may require to enable
        such   Indemnitee  to  comply  with  the   requirements  of  any  taxing
        jurisdiction. whenever any payment is to be made by

        calculating the  After-Tax-Basis  amount of such payment, to compute the
        amount of any  liability  for federal,  state or local tax imposed on or
        measured by the net income of any Indemnitee,  such computation shall be
        based on the assumption  that such taxes shall be payable at the highest
        marginal statutory rate in effect for the relevant period.

        (7)  Definition of Indemnitee.  For purposes of this Section 13(b),  the
        term  Indemnitee  shall mean and include the  successors  and assigns of
        each  respective  Indemnitee,  and for purposes of federal income taxes,
        the affiliated group of corporations and each member thereof (within the
        meaning  of  Section  1504 of the Code) of which  such  Indemnitee  is a
        member,  if such group shall file a  consolidated  united States federal
        income tax  return,  and,  for  purposes  of income or  franchise  taxes
        imposed by a particular state or local taxing  jurisdiction,  shall mean
        and include any  consolidated or combined group of which such Indemnitee
        is or shall be a member  that is  treated as such by such state or local
        taxing jurisdiction.

           (C) Supporting Material.  Upon receipt of any payment provided for by
this Section 13, the  Indemnitee  receiving the same shall provide to the Lessee
such supporting material (other than tax returns) as the Lessee shall reasonably
request.  The Lessee shall reimburse to any Indemnitee,  on an  After-Tax-Basis,
any expenses incurred in providing requested supporting material to the Lessee.

           (d) Coordination with Tax Indemnification Agreement. Any amounts that
the Lessee is liable to pay pursuant to this  Section  13(b) shall be payable by
the  Lessee  hereunder  even if such Taxes are not the  liability  of the Lessee
pursuant to the Tax Indemnification Agreement.

                 shall enter into an agreement whereby such parent confirms that
                 it shall be  secondarily  liable for) the  obligations  of such
                 Transferee under section 7(b)(1) notwithstanding such transfer;
                 and

                 (iii) such transfer shall not violate the securities Act or any
                 provision  of,  or  create  a  relationship  which  would be in

                 transferring  Owner Participant or the Transferee is a party or
                 by which its property is bound

Upon any such transfer,  the transferring  Owner  Participant  shall,  except as
expressly  provided in clause (ii) above, be released from its obligations under
this Participation  Agreement and the other Transaction  Documents to the extent
of the interest transferred. An agreement to transfer shall not in and of itself
constitute a transfer for purposes of this Section 15

                (b)  Procedure.  If the Owner  Participant  transfers all or any
part of its  interest  hereunder  pursuant  to this  Section  15, it shall  give
written notice thereof to the Lessee,  the Owner Trustee,  the Indenture Trustee
and the Loan  Participant,  specifying  the name and  address for notices to the
Transferee,  such  other  information  and  evidence  as shall be  necessary  to
establish  compliance  with  this  Section  15 and the  extent  of the  interest
transferred  to such  Transferee.  If,  as a result  of any such  transfer,  the
original Owner Participant is not to continue to receive all payments to be made
by the Indenture  Trustee to the "Owner  Participant"  under the Indenture,  the
original Owner  Participant  shall from time to time, by notice to the Indenture
Trustee,  with copies to the Lessee,  the Owner Trustee and the Collateral Trust
Trustee,  designate  the  manner  in  which  any  such  payments  to the  "Owner
Participant" are to be allocated, and the Indenture Trustee shall be entitled to
rely on such notice for all purposes. This Section 15 (other than the notice

Participant,  the Indenture Trustee, the Owner Trustee and the Owner Participant
in respect of any commissions,  fees,  judgments or other expenses of any nature

                  SECTION 19. Miscellaneous.

                  (a) Execution. This Participation Agreement may be executed in
any number of  counterparts  and by the  different  parties  hereto on  separate
counterparts,  each of  which,  when so  executed  and  delivered,  shall  be an
original,  but all such counterparts  shall together  constitute but one and the
same instrument.  Although this Participation  Agreement is dated as of the date
first above written for convenience, the actual dates of execution hereof by the
parties hereto are respectively the dates set forth under the signatures hereto,
and this Participation Agreement shall be effective on the latest such date.

                  (b) Intention of the Owner Trustee and the Owner  Participant.
Each of the Owner  Trustee and the Owner  Participant  intends to  exercise  its
rights and carry out its obligations  hereunder and under the other  Transaction
Documents  solely with a view to furthering  its own best interests and does not
have,  and does not expect to have,  any form of joint  profit  motive  with any
other Person.  The Owner Trustee and the Owner Participant shall not be required
to share any Rent to which they are entitled  under the Facility  Lease,  or the
residual value of the Undivided Interest or the Real Property Interest, with any
other  person.  The Owner  Trustee and the Owner  Participant  are not under the
control of nor shall they be deemed to be under the control of any other  Person
having any  interest in Unit 1, and shall not be the agent of or have a right or
power to bind any such Person (other than the Owner  Participant  as regards the
Owner Trustee)  without its express written  consent.  The Owner Trustee and the
Owner Participant accordingly do not intend to create any form of partnership or
joint venture with any other Person by virtue of the  transactions  contemplated
hereby  or by  any  of the  Transaction  Documents.  In  the  event  that  it is
determined,  contrary  to  the  intent  of  the  Owner  Trustee  and  the  Owner
Participant,  that, for purposes of the Code or any other income tax law, a form
of  partnership  or joint venture  exists between the Owner Trustee or the Owner

Participant  and any other Person,  the Owner Trustee and the Owner  Participant
hereby  elect to the  extent  permitted  by law (i) not to have the  partnership
provisions  of the  Code or  such  other  income  tax  law  apply  to any of the
transactions contemplated hereby or by any of the Transaction Documents and (ii)
to be treated solely as owning the Undivided Interest.

                  (c)  Governing  Law.  This  Participation  Agreement  has been
negotiated  and delivered in the State of New York and shall be governed by, and
be construed in accordance with, the laws of the State of Mew York.

                  (d) Amendments,  Supplements,  etc. Neither this Participation
Agreement  nor any of the terms hereof may be amended,  supplemented,  waived or
modified  orally,  but only by an  instrument  in  writing  signed  by the party
against which enforcement of such change is sought.

                  (e) Headings.  The headings of the sections and  paragraphs of
this  Participation  Agreement  have been inserted for  convenience of reference
only and  shall in no way  restrict  or  otherwise  modify  any of the  terms or
provisions hereof.

                (f)   Bankruptcy  of  Owner   Participant.   If  (a)  the  Owner
Participant or the Owner Trustee becomes a debtor subject to the  reorganization
provisions of the Bankruptcy Code, or any successor  provision,  (b) pursuant to
such  reorganization  provisions  the Owner  Participant or the Owner Trustee is
required,  by  reason  of the  Owner  Participant  being  held to have  recourse
liability  directly  or  indirectly  to the Holder of any Note or the  Indenture
Trustee,  to make  payment  on account of any  amount  payable as  principal  or
interest,  and  premium  (if  any),  on such  Note  and (c) such  Holder  or the
Indenture Trustee actually  receives any Excess Amount (as hereinafter  defined)
which reflects any payment by the Owner  Participant on account of clause (b) of
this  Section,  then such Holder or the Indenture  Trustee,  as the case may be,
shall promptly refund to the Owner Participant such Excess Amount.  For purposes
of this Section,  "Excess Amount" means the amount by which such payment exceeds



                                      -91-

the  amount  which  would  have  been  received  on or prior to the date of such
payment by such Holder or the Indenture  Trustee if the Owner Participant or the
Owner Trustee had not become  subject to the recourse  liability  referred to in
clause (b) of this Section. Nothing contained in this Section shall prevent such
Holder or the Indenture Trustee from enforcing any personal recourse  obligation
(and retaining the proceeds thereof) of the Owner Participant expressly provided
for under this Participation Agreement.

           (g) Entire Agreement.  This  Participation  Agreement  (including the
Schedules hereto),  the other Transaction  Documents and the Financing Documents
supersede  all prior  agreements,  written or oral,  between or among any of the
parties hereto relating to the transactions  contemplated hereby and thereby and
each of the  parties  hereto  represents  and  warrants  to the others that this
Participation  Agreement and the other  Transaction  Documents and the Financing
Documents  constitute  the entire  agreement  among the parties  relating to the
transactions contemplated hereby and thereby.

(h)  Publicity.  Each party hereto  agrees that it will not issue or release for
external  publication any article or advertising or publicity matter relating to
the transaction contemplated hereby or any similar transaction and mentioning or
implying the identity of the Owner Participant without the prior written consent
of the Owner Participant;  provided,  however, that the Owner Participant agrees
that such written  consent shall not be withheld if such  disclosure is required
by Applicable Law.

liability for a single "nuclear incident" of "persons indemnified" (as each such
term is defined in the  Price-Anderson  Act as in effect on the closing Date) is

obligation imposed as of the date hereof on licensees of the NRC; (4) any change

transactions contemplated by the Transaction Documents unauthorized,  illegal or
otherwise  contrary to Applicable Law; (5) any change in, or new  interpretation

(each as in effect on the Closing Date)  constituting an assertion to the effect
that the  exercise by the Owner  Trustee or the Owner  Participant  of any right
(irrespective  of the event  giving  rise to such right)  under any  Transaction
Document would constitute  impermissable control over Unit 1 or the licensees of
Unit 1, other than an assertion that affects such rights in a manner  consistent

increased  real or potential  liability in respect of a "nuclear  incident"  (as
defined in the  Price-Anderson  Act) and such policy of  insurance  shall not be
immediately  replaced by insurance  effective  immediately upon such suspension,
termination,  amendment or  supplementation  which, in the reasonable opinion of

terminated, suspended, amended or supplemented, unless the "aggregate liability"
for a "nuclear  incident" of "persons  indemnified"  (as each term is defined in
the Atomic  Energy Act of 1954, as amended) is reduced by an amount equal to the
amount of liability insurance so terminated,  suspended, amended or supplemented
and, in the reasonable opinion of the Owner Participant, it may not otherwise be
exposed, either during or subsequent to the Lease Term, to any increased real or
potential  liability in respect of a "nuclear incident" as a consequence of such

registration,  and registration of transfer and exchange, of the Notes by series
and in which  shall be  entered  the names and  addresses  of the owners of such
Notes and the principal  amounts of the Notes owned by them,  respectively.  For

pledge or  assignment) or to exchange any  outstanding  Note held by such Holder
for a new Note or Notes of the same series may surrender such  Outstanding  Note
at the Indenture  Trustee's  Office,  together with the written  request of such
Holder,  or of its  attorney  duly  authorized  in  writing,  in each  case with

specifying the authorized denomination or denominations of any new Note or Notes
to be issued and the name and  address of the Person or Persons in whose name or
names the Note or Notes are to be  registered  (either as pledgee or assignee or

satisfaction of the  requirements of sections 4.5 and 4.6 hereof,  the Indenture
Trustee shall  register such Note or Notes in the name or names of the Person or
Persons as shall be specified in the written request and, in the case in which a
new Note or Notes are to be issued,  the Owner  Trustee  shall  execute  and the
Indenture  Trustee shall  authenticate and deliver such new Note or Notes of the
same series,  in the same aggregate  principal amount and dated the same date as
the  Outstanding   Note   surrendered,   in  such  authorized   denomination  or
denominations  as shall be  specified  in the  written  request.  The  Indenture
Trustee  shall make a notation on each new Note of the amount of all payments of
principal  theretofore made on the old Note or Notes in exchange or transfer for
which any new Note has been  issued and the date to which  interest  on such old
Note or Notes has been paid.

                  SECTION 4.3.  Cancellation of Notes.

                All Notes  surrendered  to the Indenture  Trustee for payment in
full,  prepayment  in full or  registration  of transfer  or  exchange  shall be
cancelled  by it;  and no Notes  shall  be  issued  in lieu  thereof  except  as
expressly  permitted by any of the provisions of this  Indenture.  The Indenture
Trustee shall destroy cancelled Notes held by it in a manner satisfactory to the
Owner Trustee and deliver a certificate of destruction to the Owner Trustee.  If
the Owner Trustee shall acquire any of the Notes, such acquisition shall not


                                      -23-

operate as a redemption of or the satisfaction of the  indebtedness  represented
by such  Notes  unless and until the same shall be  delivered  to the  Indenture
Trustee for cancellation.

                  SECTION 4.4.  Limitation on Timing of Registration of Notes.

                  The  Indenture  Trustee  shall  not be  required  to  register
transfers or exchanges of Notes on any date fixed for the payment or  prepayment
of principal  of or interest on the Notes or during the fifteen  days  preceding

                If not  prohibited  by the  Securities  Act,  each Note shall be
delivered to the initial Holder thereof without  registration of such Note under
the securities Act and without  qualification  of this Indenture under the Trust
Indenture  Act.  Prior to any transfer of any Note,  in whole or in part, to any
Person other than the collateral Trust Trustee, the Holder thereof shall furnish
to the  Lessee,  the  Indenture  Trustee  and the Owner  Trustee  an  opinion of
counsel, which opinion and which counsel shall be reasonably satisfactory to the
Indenture  Trustee,  the Owner  Trustee and the Lessee,  to the effect that such
transfer will not violate the  registration  provisions of the Securities Act or
require  qualification  of this Indenture under the Trust Indenture Act, and all
Notes  issued  hereunder  shall be  endorsed  with a  legend  which  shall  read
substantially as follows:

                 This Note has not been  registered  under the securities Act of
                 1933 and may not be  transferred,  sold or offered  for sale in
                 violation of such Act.

                  SECTION 4.6.  Charges upon Transfer or Exchange of Notes.

                  As a further condition to registration of transfer or exchange
of any Note,  the Indenture  Trustee and the Owner Trustee may charge the Holder
thereof for any stamp  taxes or  governmental  charges  required to be paid with
respect to such registration of transfer or exchange.

                  SECTION 4.7.  Inspection of Register of Notes.

                  The  register  of the  Holders  of the  Notes  referred  to in
section 4.1 shall at all  reasonable  times be open for inspection by any Holder
of a Note.  upon  request by any Holder of a Note,  or the Owner  Trustee or the
Lessee,  the Indenture Trustee shall furnish such Person, at the expense of such
Person,  with a list of the names and  addresses of all Holders of Notes entered
on the register kept by the Indenture Trustee  indicating the series,  principal
amount and number of each Note held by each such Holder.

                  SECTION 4.8.  Ownership of Notes.

                (a) Prior to due presentment for registration of transfer of any
Note, the Owner Trustee and the Indenture  Trustee may deem and treat the Holder
of record of such Note as the  absolute  owner of such Mote for the  purpose  of
receiving  payment of all amounts  payable with respect to such Note and for all
other purposes, and neither the Owner Trustee nor the Indenture Trustee shall be
affected by any notice to the contrary.

                  (b) The Owner Trustee and the Indenture  Trustee may, in their
discretion,  treat the Holder of record of any Note as the owner thereof without
actual production of such Note for any purpose hereunder,  except as provided in
the last sentence of section 3.8 hereof.

                  (c) Neither the Owner Trustee nor the Indenture  Trustee shall
be bound to take notice of or carry out the execution of any trust in respect of
any Note,  and may  register  the  transfer of the same on the  direction of the
Holder of record thereof,  whether named as trustee or otherwise, as though such
Holder were the beneficial owner thereof.

                  (d) The  receipt  by the  Holder  of record of any Note of any
payment of principal, premium or interest shall be a good discharge to the Owner
Trustee and the Indenture Trustee for the same and neither the Owner Trustee nor
the  Indenture  Trustee  shall be bound to  inquire  into the  title of any such
Holder.

                  SECTION 5.1.  Basic Rent Interest on Overdue  Installments  of
Basic Rent and prepayments of Interest.

                  Except as  otherwise  provided  in Section  5.3 or 5.7 hereof,
each  payment  of  Basic  Rent,  as well as any  payment  of  supplemental  Rent
representing  interest on overdue  installments  of Basic Rent,  received by the
Indenture  Trustee at any time, shall be distributed by the Indenture Trustee in
the  following  order of  priority:  first,  so much of such payment as shall be
required  to pay in full the  aggregate  amount of the  payment or  payments  of
principal  and/or interest (as well as any interest on overdue  principal or, to
the extent permitted by law, interest) then due and unpaid on all Notes shall be
distributed  to the Holders of the Notes ratably,  without  priority of one over
the  other,  in the  proportion  that the  aggregate  amount of such  payment or
payments  then due and unpaid on all Notes held by each such Holder on such date
bears to the aggregate amount of such payment or payments then due and unpaid on
all Notes outstanding on such date,  without priority of interest over principal



                                      -26-



<PAGE>

or principal over  interest;  and second,  the balance,  if any, of such payment
remaining  thereafter shall be distributed,  concurrently  with any distribution
pursuant to clause first  hereof,  to the Owner  Trustee or as the Owner Trustee
may direct.  If there shall not otherwise have been  distributed on any date (or
within any applicable  period of grace),  pursuant to this Section 5.1, the full
amount then  distributable  pursuant to clause  first of this  Section  5.1, the
Indenture  Trustee shall distribute  other payments  referred to in sections 5.4
and 5.5 then  held by it or  thereafter  received  by it,  except  as  otherwise
provided in section 5.3, to the Holders of all Notes to the extent  necessary to
enable it to make all the distributions  then due pursuant to such clause first;
provided that to the extent any  distribution is made from amounts held pursuant
to section  5.4 hereof and the Lessee  subsequently  makes the  payment of Basic
Rent or supplemental  Rent in respect of which such  distribution was made, such
payment of Basic Rent or supplemental Rent shall, unless an Indenture Default or
an Indenture Event of Default shall have occurred and be continuing,  be applied
to the purpose for which such amount held pursuant to section 5.4 had been held,
subject,  in all cases,  to the terms of section  5.4.  The portion of each such
payment  made  to  the  Indenture  Trustee  which  is to be  distributed  by the
Indenture  Trustee  in payment of Notes  shall be  applied  in  accordance  with
Section 3.11. Any payment received by the Indenture  Trustee pursuant to section
6.8 shall be distributed to the Holders of the Notes, ratably,  without priority
of one over the other,  in the  proportion  that the  amount of such  payment or
payments  then due and unpaid on all Notes held by each such Holder bears to the
aggregate  amount of the payments then due and unpaid on all Notes  Outstanding.
Amounts  distributed by the Indenture Trustee pursuant to this section 5.1 shall
be  distributed  as  promptly as  practicable  after such  amounts are  actually
received by the  Indenture  Trustee;  provided,  however,  that in the event the
Indenture  Trustee  shall be directed to make payments to the Holder of any Note
by wire transfer in accordance with Section 3.8 hereof,  any amounts received by
the Indenture  Trustee after 11:00 A.M.,  New York City time, may be distributed
on the following Business Day.

Occurrence of Special Purchase Event.

                  If an Event of toss or Deemed  Loss Event  shall  occur or the
Lessee shall exercise the Cure Option, and if either the Assumption Agreement or
the  undivided  Interest  Indenture  Supplement  shall  have been  executed  and
delivered,  any amounts of Casualty value, special casualty Value or Fair Market
Sales value  received or held by the Indenture  Trustee in respect of such Event
of Loss or Deemed Loss Event or exercise  of the Cure  Option  shall,  except as
otherwise  provided  in  Section  5.3,  be  distributed  forthwith  to the Owner
Participant.  If the  Lessee or the  Owner  Trustee,  as the case may be,  shall
exercise  its option to  terminate  the  Facility  Lease  pursuant to Section 14
thereof, or the special Purchase Event shall have occurred,  then there shall be
prepaid,  on the date payments of proceeds with respect  thereto are received by
the Indenture Trustee (or as soon thereafter as practicable) under section 13(c)
or 14 of the Facility Lease as the case may be, the unpaid  principal  amount of
all  Notes,  together  with the  premium,  if any,  and all  accrued  but unpaid
interest thereon to the date of such prepayment. Notice of such prepayment shall
be given as  provided in Section  3.9(c) and may  provide  that it is subject to
receipt of funds for such prepayment.  Except as. otherwise  provided in section
5.3 or 5.7, any payments  received and amounts realized by the Indenture Trustee
upon  exercise of the Lessee's or the Owner  Trustee's  option to terminate  the
Facility  Lease  under  section  14 thereof or upon  occurrence  of the  Special

                  Except as  otherwise  provided in Section  5.7,  all  payments
received and amounts  realized by the Indenture  Trustee in respect of the Lease
Indenture Estate  (including any amounts realized by the Indenture  Trustee from
the  exercise of any remedies  pursuant to the  Facility  Lease or Article VI of
this Indenture)  after an Indenture Event of Default  referred to in section 6.2
shall  have  occurred  and be  continuing  and the Notes  have been  accelerated
pursuant to Section 7.1, as well as all payments  thereafter received or amounts
then held by the Indenture Trustee as part of the Lease Indenture Estate,  shall
be distributed by the Indenture Trustee in the following order of priority:

                  first,  so  much of such  payments  or  amounts  as  shall  be
        required to reimburse the Indenture  Trustee for any Trustee's  Expenses
        (to the  extent not  previously  reimbursed)  and to pay the  reasonable
        remuneration of the Indenture Trustee, shall be applied by the Indenture
        Trustee to such reimbursement and payment;

                  second, so much of such payments or amounts remaining as shall
        be required to pay in full the aggregate  unpaid principal amount of all
        Notes,  together with premium,  if any, plus accrued but unpaid interest
        (as well as interest on overdue  principal and, to the extent  permitted
        by law, on overdue interest) thereon to the date of distribution,  shall
        be  distributed  to the Holders of such Notes and in case the  aggregate
        amount so to be distributed  shall be insufficient to pay all such Notes
        in full as  aforesaid,  then ratably,  without  priority of one over the
        other, in the proportion that the aggregate  unpaid  principal amount of
        all such Notes held by each such Holder,  together with premium, if any,
        plus  accrued but unpaid  interest  thereon to the date of  distribution
        bears to the aggregate unpaid  principal  amount of all Notes,  together
        with premium,  if any, plus accrued but unpaid  interest  thereon to the
        date of distribution;

                  third, so much of such payments or amounts  remaining as shall
        be  required  to pay the  present  or  former  Holders  of the Notes the

        reimbursed)  shall  be  distributed  to such  Holders;  and in case  the
        aggregate  amount so to be paid to all such Holders in  accordance  with
        this  clause  third  shall be  insufficient  to pay all such  amounts as
        aforesaid,  then ratably, without priority of one over the other, in the
        proportion  that the amount of such indemnity or other payments to which
        such Person is entitled bears to the aggregate  amount of such indemnity
        or other payments to which all such Persons are entitled;

                fourth,  the  balance,  if any,  of  such  payments  or  amounts
         remaining shall be applied to the payment of any other  indebtedness at
         the time due and owing to the  Indenture  Trustee or the Holders of the
         Notes which this Indenture by its terms secures; and

                fifth,  the  balance,  if  any,  of  such  payments  or  amounts
         remaining  thereafter  shall be distributed to or upon the direction of
         the Owner Trustee.

                SECTION 5.4.  Amounts  Received for which provision Is Made in a
Transaction Document.

                Except as otherwise  provided in section 5.1, 5.3 or 5.7 hereof,
any payments received by the Indenture Trustee in respect of the Lease Indenture
Estate  for  which  provision  as  to  the  application  thereof  is  made  in a
Transaction  Document shall be applied to the purpose for which such payment was
made in accordance with the terms of such Transaction  Document,  as determined,
in the first instance, from instructions or other information  accompanying such
payment,  or, otherwise,  in accordance with instructions from the payor of such
payments.

                  SECTION 5.5.  Amounts Received for Which No Provision Is Made.

                  Except as otherwise  provided in section 5.1, 5.2, 5.3 or 5.7,

        (a) for which no  provision as to the  application  thereof is made in a
        Transaction Document or elsewhere in this Article V shall be held by the
        Indenture Trustee as part of the Lease Indenture Estate, and

        (b) to the extent received or realized at any time after payment in full

be made to the Owner Trustee hereunder shall be made to the Owner Participant by
wire transfer of immediately  available  funds as soon as practicable but in any
event no later than the close of business on the date of receipt  (assuming  the

Participant  shall  from time to time  designate  in  writing  to the  Indenture

contrary  notwithstanding,  any  Excepted  Payment  received  at any time by the

omission by the Indenture Trustee in the exercise of any right,  power or remedy
or in the  pursuance of any remedy shall impair any such right,  power or remedy

                  SECTION 6.7.  Waiver of Past Defaults.

                  Any past Indenture  Default or Indenture  Event of Default and
its  consequences  may be waived by the Indenture  Trustee,  except an Indenture
Default or an Indenture  Event of Default (i) in the payment of the principal of
or interest on any Note,  subject to the  provisions  of Section 7.1 hereof,  or
(ii) in respect of a covenant or  provision  hereof  which,  under  Section 10.2
hereof,  cannot be modified or amended  without the con-sent of each Holder of a
Note then outstanding. Upon any such waiver, such Indenture Default or Indenture
Event of Default shall cease to exist,  and any other Indenture 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 Indenture
Default or Indenture Event of Default or impair any right consequent thereon.

                SECTION 6.8. Right of Owner Trustee to Pay Rent;  Note Purchase;
Substitute Lessee.

                Anything  in this  Article  VI or  Article  VII to the  contrary
notwithstanding:

                  (a) an  Indenture  Event of Default  shall be deemed  cured if
such  Indenture  Event of  Default  results  from  non-payment  of Basic Rent or
supplemental  Rent under the Facility Lease,  and the Owner Trustee or the Owner
Participant  shall  have paid all  principal  of and  interest  on the Notes due
(other  than by  acceleration)  on the date such  Basic Rent was  payable  (plus
interest on such amount as required  hereby) within 20 days after the receipt by
the Owner  Trustee of notice of such  non-payment,  such receipt to be evidenced
by,  among  other  things,  any  notice  thereof  given to the Owner  Trustee in
accordance with the notice provisions of the Participation  Agreement. The owner
Trustee  or the Owner  Participant,  upon  exercising  cure  rights  under  this
paragraph  (a),  shall not  obtain  any Lien on any part of the Lease  Indenture
Estate on  account  of such  payment  for' the costs and  expenses  incurred  in
connection  therewith  nor,  except  as  expressly  provided  in the  succeeding

sentence, shall any claims of the Owner Trustee or the Owner Participant against
the Lessee or any other Person for the repayment  thereof impair the prior right
and security  interest of the  Indenture  Trustee in and to the Lease  Indenture
Estate. Upon any payment by the Owner Trustee or the Owner Participant  pursuant
to this Section 6.6, the Owner Trustee or the Owner Participant, as the case may
be, shall (to the extent of such payment made by it) be subrogated to the rights
of the Indenture  Trustee and the Holders of the Notes to receive the payment of
Rent with respect to which the Owner Trustee or the Owner  Participant made such
payment and interest on account of such Rent payment being overdue in the manner
set  forth in the next  sentence.  If the  Indenture  Trustee  shall  thereafter
receive such payment of Rent or such  interest,  the  Indenture  Trustee  shall,
notwithstanding  the  requirements  of section  5.10 on the date such payment is
received by the Indenture Trustee,  remit such payment of Rent (to the extent of
the payment made by the Owner Trustee or the Owner Participant  pursuant to this
section 6.6) and such interest to the Owner Trustee or the Owner Participant, as
the case may be, in reimbursement for the funds so advanced by it.

                  (b) Each Holder of a Note agrees, by acceptance thereof,  that
if the Notes  have been  accelerated  pursuant  to  section  7.1,  and the Owner
Trustee,  within 30 days  after  receiving  notice  from the  Indenture  Trustee
pursuant to Section  7.1  hereof,  shall give  written  notice to the  Indenture
Trustee  of the  Owner  Trustee's  intention  to  purchase  all of the  Notes in
accordance with this  paragraph,  accompanied by assurances of the Owner Trustee
to purchase the Notes,  then,  upon receipt  within 10 Business  Days after such
notice  from the  Owner  Trustee  of an  amount  equal to the  aggregate  unpaid
principal  amount of and any premium  with respect to any unpaid Notes then held
by such Holder, together with accrued but unpaid interest thereon to the date of
such  receipt (as well as any interest on overdue  principal  and, to the extent
permitted by law, interest),  such Holder will forthwith sell, assign,  transfer
and convey to the Owner Trustee (without  recourse or warranty of any kind other



                                      -39-

than of title to the Notes so conveyed) all of the right,  title and interest of
such Holder in and to the Lease.  Indenture Estate, this Indenture and all Notes
held by such  Holder;  provided,  that no such  Holder  shall be  required so to
convey unless (1) the Owner Trustee shall have  simultaneously  tendered payment
for all other Notes issued by the Owner Trustee at the time Outstanding pursuant
to this paragraph and (2) such  conveyance is not in violation of any Applicable
Law.

                  (c) Each  Holder of a Note  further  agrees by its  acceptance
thereof that the Owner Trustee  shall have the right,  pursuant to Section 16 of
the  Facility  Lease,  to  terminate  the  Facility  Lease  and,  in  connection
therewith,  to arrange for the  substitution of another Person as lessee under a
new  lease  substantially   similar  to  the  Facility  Lease  (hereinafter  the
Substituted  Lessee) and,  subject to: (i) any Indenture  Event of Default under
paragraphs  (d) and (e) of Section 6.2 having  been cured by the Owner  Trustee,
(ii) the  Substituted  Lessee's  assuming all of the  obligations  of the Lessee
under the Facility Lease and (iii) the  Substituted  Lessee's having an assigned
credit rating by Standard & Poor's  Corporation and Moody's  Investors  Service,
Inc. (or, if either of such  organizations  shall not rate securities  issued by
such Substituted Lessee, by any other nationally  recognized rating organization
in the United States of America) with respect to at least one series of its debt
obligations  or  preferred  stock equal to or better than the ratings  assigned,
immediately  prior to such  substitution,  by such  organizations  to comparable
securities of the Lessee  immediately prior to such substitution but in no event
less than "investment  grade", then the Facility Lease between the Owner Trustee
and such Substituted Lessee shall, for all purposes of this Indenture, be deemed
to be the Facility Lease subject to the lien of this Indenture.

                  SECTION 6.9.  Further Assurances.

                  Subject to section 7.6 hereof, the Owner Trustee covenants and
agrees from time to time to do all such acts and execute all such instruments of
further assurance as shall be reasonably  requested by the Indenture Trustee for
the purpose of fully carrying out and effectuating this Indenture and the intent
hereof.

any act  required to be made or  performed by it hereunder or under the Facility
Lease or if the Owner Trustee shall fail to release any Lien affecting the Lease
Indenture Estate which it is required to release by the terms of this Indenture,
the Indenture  Trustee,  without  notice to or demand upon the Owner Trustee and
without waiving or releasing any obligation or default,  may (but shall be under
no obligation to) at any time  thereafter  make such payment or perform such act
for the account and at the expense of the Lease  Indenture  Estate.  All sums so
paid by the  Indenture  Trustee and all costs and  expenses  (including  without
limitation   reasonable   fees  and   expenses   of  legal   counsel  and  other
professionals)  so incurred,  together  with  interest  thereon from the date of
payment or occurrence,  shall constitute additional indebtedness secured by this
Indenture  and shall be paid from the Lease  Indenture  Estate to the  Indenture
Trustee on demand.  The  Indenture  Trustee  shall not be liable for any damages
resulting  from any such  payment  or  action  unless  such  damages  shall be a
consequence  of  willful  misconduct  or  gross  negligence  on the  part of the
Indenture Trustee.

                  SECTION 6.11.  Certain Other Rights of the Owner Trustee.

                Notwithstanding any provision to the contrary in this Indenture,
the Owner Trustee  shall at all times retain,  to the exclusion of the Indenture
Trustee,  all rights of the Owner  Trustee to exercise any election or option or
to make any decision or determination or to give or receive any notice, consent,
waiver  or  approval  or to take any other  action  under or in  respect  of the
Facility  Lease,  as well as all rights,  powers and remedies on the part of the

or in  equity or  otherwise,  arising  out of any  Default  or Event of  Default
subject,  however,  to Section 10.2.  Without the prior  written  consent of the
indenture  Trustee,  the exercise of any of the aforesaid  rights so retained by
the Owner  Trustee  shall not be exercised in such a manner as to (i) reduce the
amounts  payable  by the  Lessee  under the  Facility  Lease  below the  amounts
necessary  to provide the owner  Trustee with  sufficient  monies to make timely
payments in full of amounts due with respect to the principal of and premium, if
any, and interest on all Notes or (ii) rescind or terminate  the Facility  Lease
pursuant to section 16 thereof.  Nor shall the Owner Trustee  exercise any other
right or remedy under the Facility  Lease the effect of which would be to effect
such rescission or termination.

Indenture Event of Default, an Event of Default, a Deemed Loss Event or an Event
of Loss, the Owner Trustee shall give prompt written notice thereof to the Owner

discretion  may, or upon receipt of a Directive  shall, by written notice to the
Owner  Trustee,  declare the unpaid  principal  amount of all Notes with accrued
interest thereon to be immediately due and payable,  upon which declaration such
principal  amount and much accrued  interest  shall  immediately  become due and
payable  without  further  act or notice of any kind.  For all  purposes of this
Indenture, in the absence of actual knowledge, neither the Owner Trustee nor the
Indenture  Trustee  shall be deemed to have  knowledge of an Indenture  Event of
Default or Event of Default except that the Indenture Trustee shall be deemed to
have knowledge of the failure of the Lessee to pay any installment of Basic Rent
within 10 Business  nays after the same shall  become due.  For purposes of this
section 7.1, neither the Owner Trustee nor the Indenture Trustee shall be deemed
to have actual  knowledge of any Indenture  Event of Default,  Event of Default,
Deemed Loss Event or Event of Loss unless it shall have received  notice thereof
pursuant to section 11.6 hereof or such  Indenture  Event of Default or Event of
Default shall actually be known by an officer in the corporate trust  department
of the Owner  Trustee or by an officer in the corporate  Trustee  Administration

                The  Indenture  Trustee shall not be required to take or refrain
from taking any action under section 7.1 or 7.2 or Article VI hereof which shall
require the Indenture Trustee to expend or risk its own funds or otherwise incur
any financial liability unless the Indenture Trustee shall have been indemnified
by the  Holders  of the Notes  against  liability,  cost or  expense  (including
counsel fees) which may be incurred in connection  therewith,  or unless, in the
reasonable  judgment of the Indenture  Trustee,  the  indemnities  of the Lessee
shall be adequate for such  purpose;  provided,  however,  that if the Holder of
such Notes is the Collateral Trust Trustee, the unsecured written undertaking of

indemnity  for purposes of this  Section.  The  Indenture  Trustee  shall not be
required  to take any action  under  Section 7.1 or 7.2 or Article VI hereof nor
shall any other  provision  of this  Indenture be deemed to impose a duty on the

determine,  or shall have been advised by counsel, that such action is likely to
result in  personal  liability  or is  contrary  to the  terms  hereof or of the
Facility Lease or is otherwise contrary to law.

distributed  by the  Indenture  Trustee in payment of Notes  shall be applied in
accordance  with Section 3.11.  Any payment  received by the  Indenture  Trustee
pursuant  to  Section  6.8 shall be  distributed  to the  Holders  of the Notes,

this  section 5.1 shall be  distributed  as promptly as  practicable  after such
amounts are actually received by the Indenture Trustee provided,  however,  that

Lessee shall exercise the Cure Option, and if either the Assumption Agreement or
the  Undivided  Interest  Indenture  Supplement  shall  have been  executed  and
delivered,  any amounts of Casualty Value, special casualty Value or Fair Market

Participant.  If the Lessee or Owner Trustee, as the case may be, shall exercise
its option to terminate the Facility  Lease  pursuant to section 14 thereof,  or
the special Purchase Event shall have occurred,  then there shall be prepaid, on
the date payments or proceeds with respect thereto are received by the Indenture
Trustee (or as soon thereafter as practicable)  under section 13(c) or 14 of the

pursuant to Section 7.1, as well as all payments  thereafter received or amounts
then held by the Indenture Trustee as part of the Lease Indenture Estate,  shall

        remuneration of the Indenture Trustee, shall be applied by the Indenture
        Trustee to such reimbursement and payment;

                  second, so much of such payments or amounts remaining as shall
        be required to pay in full the aggregate  unpaid principal amount of all
        Notes,  together with premium1 if any, plus accrued but unpaid  interest
        (as well as interest on overdue  principal and, to the extent  permitted
        by law, on overdue interest) thereon to the date of distribution,  shall
        be  distributed  to the Holders of such Notes and in case the  aggregate
        amount so to be distributed shall be insufficient to pay all such

        the other, in the proportion that the aggregate  unpaid principal amount
        of all such Notes held by each such Holder,  together with  premium,  if
        any,  plus  accrued  but  unpaid   interest   thereon  to  the  date  of
        distribution  bears to the  aggregate  unpaid  principal  amount  of all
        Notes,  together with premium,  if any, plus accrued but unpaid interest

        aggregate  amount so to be paid to all such Holders in  accordance  with
        this  clause  third  shall be  insufficient  to pay all such  amounts as

        proportion  that the amount of such indemnity or other payments to which
        such Person is entitled bears to the aggregate  amount of such indemnity
        or other payments to which all such Persons are entitled:

                  fourth,  the  balance,  if any,  of such  payments  or amounts

        the time due and owing to the  Indenture  Trustee or the  Holders of the
        Notes which this Indenture by its terms secures: and

                  fifth,  the  balance,  if any,  of such  payments  or  amounts
        remaining  thereafter  shall be  distributed to or upon the direction of
        the owner Trustee.

a Transaction Document.

                  Except  as  otherwise  provided  in  section  5.1,  5.3 or 5.7
hereof,  any payments  received by the Indenture Trustee in respect of the Lease

made in accordance with the terms of such Transaction  Document,  as determined,

and on such terms as the Indenture Trustee, in its uncontrolled discretion,  may
determine,  or as may be  required  by  Applicable  Law,  so long  as the  Owner
participant  and the  Owner  Trustee  are  afforded  a  commercially  reasonable
opportunity  to bid for  all or  such  part of the  Lease  Indenture  Estate  in

time to time and as often and in such  order as may be deemed  expedient  by the
Indenture  Trustee and the  exercise  or the  beginning  of the  exercise of any
right,  power or remedy  shall not be  construed  to be a waiver of the right to
exercise at the same time or thereafter  any other right,  power or remedy,  and

power or remedy or in the  pursuance  of any remedy shall impair any such right,

Default or an Indenture  Event of Default (i) in the payment of the principal of
or interest on any Note,  subject to the  provisions  of Section 7.1 hereof,  or
(ii) in respect of a covenant or  provision  hereof  which,  under  Section 10.2
hereof,  cannot be modified  or amended  without the consent of each Holder of a
Note then Outstanding. Upon any such waiver, such Indenture Default or Indenture
Event of Default shall cease to exist,  and any other Indenture 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 Indenture
Default or Indenture Event of Default or impair any right consequent thereon.

Purchase; Substitute Lessee.

Supplemental  Rent under the Facility Lease,  and the Owner Trustee or the Owner
Participant  shall  have paid all  principal  of and  interest  on the Notes due
(other  than by  acceleration)  on the date such  Basic Rent was  payable  (plus

the Owner  Trustee of notice of such  non-payment,  such receipt to be evidenced
by,  among  other  things,  any  notice  thereof  given to the Owner  Trustee in
accordance with the notice provisions of the Participation  Agreement. The Owner
Trustee  or the Owner  Participant,  upon  exercising  cure  rights  under  this
paragraph  (a),  shall not  obtain  any Lien on any part of the Lease  Indenture
Estate  on  account  of such  payment  for the costs and  expenses  incurred  in

connection  therewith  nor,  except  as  expressly  provided  in the  succeeding
sentence, shall any claims of the Owner Trustee or the Owner Participant against
the Lessee or any other Person for the repayment  thereof impair the prior right
and security  interest of the  Indenture  Trustee in and to the Lease  Indenture
Estate. Upon any payment by the Owner Trustee or the Owner Participant  pursuant
to this Section 6.8, the Owner Trustee or the Owner Participant, as the case may

of the  Indenture  Trustee and the holder of the Notes to receive the payment of
Rent with respect to which the Owner Trustee or the Owner  Participant made such
payment and interest on account of such Rent payment being overdue in the manner
set  forth in the next  sentence.  If the  Indenture  Trustee  shall  thereafter
receive such payment of Rent or such  interest,  the  Indenture  Trustee  shall,
notwithstanding  the  requirements  of section  5.1, on the date such payment is
received by the Indenture Trustee,  remit such payment of Rent (to the extent of
the payment made by the Owner Trustee or the Owner Participant  pursuant to this
section 6.8) and such interest to the Owner Trustee or the Owner Participant, as
the case may be, in reimbursement for the funds so advanced by it.

if the Notes  have been  accelerated  pursuant  to  Section  7.1,  and the Owner
Trustee,  within 30 days  after  receiving  notice  from the  Indenture  Trustee
pursuant to section 7 a 1 hereof,  shall give  written  notice to the  Indenture
Trustee  of the  Owner  Trustee's  intention  to  purchase  all of the  Notes in
accordance with this  paragraph,  accompanied by assurances of the Owner Trustee
to purchase the Notes,  then,  upon receipt  within 10 Business  Days after such
notice  from the  Owner  Trustee  of an  amount  equal to the  aggregate  unpaid
principal  amount of and any premium  with respect to any unpaid Notes then held
by such Holder, together with accrued but unpaid interest thereon to the date of
such  receipt (as well as any interest on overdue  principal  and, to the extent
permitted by law, interest),  such Holder will forthwith sell, assign,  transfer
and convey to the Owner Trustee (without  recourse or warranty of any kind other
than of title to the Notes so conveyed) all of the right,  title and interest of
such Holder in and to the Lease Indenture  Estate,  this Indenture and all Notes
held by such  Holder;  provided,  that no such  Holder  shall be  required so to

for all other Notes issued by the Owner Trustee at the time outstanding pursuant
to this paragraph and (2) such  conveyance is not in violation of any Applicable
Law.

thereof that the Owner Trustee  shall have the right,  pursuant to section 16 of
the  Facility  Lease,  to  terminate  the  Facility  Lease  and,  in  connection
therewith,  to arrange for the  substitution of another Person as lessee under a
new  lease  substantially   similar  to  the  Facility  Lease  (hereinafter  the
Substituted  Lessee) and,  subject to: (i) any Indenture  Event of Default under

such Substituted Lessee, by any other nationally  recognized rating organization
in the United States of America) with respect to at least one series of its debt
obligations  or  preferred  stock equal to or better than the ratings  assigned,
immediately  prior to such  substitution,  by such  organizations  to comparable
securities of the Lessee  immediately prior to such substitution but in no event
less than "investment  grade", then the Facility Lease between the Owner Trustee
and such Substituted Lessee shall, for all purposes of this Indenture, be deemed
to be the Facility Lease subject to the lien of this Indenture.

                SECTION 6.9.  Further Assurances.

                  Subject to Section 7.6 hereof, the Owner Trustee covenants and
agrees from time to time to do all such acts and execute all such instruments of
further assurance as shall be reasonably  requested by the Indenture Trustee for
the purpose of fully carrying out and effectuating this Indenture and the intent
hereof.

                  6.8 All payments made by the  Participants to Phoenix pursuant
         to Sections  6.S and 6.6 hereof  shall be  credited by Phoenix  against
         amounts due from the  Participants  pursuant  to Section 8 hereof.  For

                  6.10 It is understood that the volumes of Uncommitted Effluent
         available  and the volumes of Effluent  required for electric  electric
         generation  are  estimates  and that the actual  needs in future  years
         could be less, but the  construction of generating units is intended to
         parallel the needs for power and availability of Uncommitted Effluent.

7.       SALE OF EFFLUENT; QUALITY OF EFFLUENT; PROCESSING SERVICE:

                  7.1  When  the  Participants  desire  to  exercise  all or any
         portion  of the Unit 1 Option,  Unit 2 Option,  Unit 3 Option or Unit 4
         Option,  in each or any  case  pursuant  to  Section  6.2  hereof,  the
         Participants  shall promptly execute and deliver to Phoenix one or more
         completed  instruments  in the  form  of  Exhibit  D,  which  shall  be
         effective  as of  the  effective  date  provided  in  such  instrument,
         providing for the sale, transfer, delivery and right to use Effluent in
         the   amounts  of  the  Unit  1  Water   Requirements,   Unit  2  Water
         Requirements, Unit 3 Water Requirements or Unit 4 Water Requirements or
         so  much  thereof  as the  Participants  have  exorcised  their  option
         therefor. The source and quality of Effluent to be transferred from and
         processed  in the 23rd  Avenue  Plant  and to be  transferred  from and
         processed  in the 91st  Avenue  Plant shall be as shown on Exhibit B In

         Participants  exercise such  Options,  in each and any case, in amounts
         less than the amounts indicated in the Options, then the balance of the
         Effluent in the amount for which the Option is not  exercised,  in each
         aria any case, shall become Uncommitted Effluent, not under Option, and
         available to be used at the Cities' sole discretion.

                  7.2  Following  any  execution  of an  instrument  pursuant to
         Section 7 hereof and  during  the term  thereof as set forth in Section
         7.S hereof,  Phoenix  shall collect  waste-water,  process the same and
         deliver  Effluent of the  quality  shown on Exhibit E to either or both
         the 23rd Avenue Plant Delivery Point and the 91st Avenue Plant Delivery
         Point as the  Participants  may from time to time  designate and in the
         amounts  as the  Participants  have  exercised  their  Option  thereof;
         provided  that such amounts are  available at the  designated  delivery
         point;  and  provided,  however,  that the  Participants  shall  not be
         obligated  to  accept  delivery  of  Effluent  which  does not meet the
         quality set forth in Exhibit E.

                  7.3 Phoenix on behalf of itself and the other Cities covenants
         and agrees that it will operate,  maintain, repair and replace the 23rd
         Avenue Plant and 91st Avenue Plant in at least  substantially  the same
         condition  as  they  exist  upon  the  date  of the  execution  of this
         Agreement,  ordinary  wear and tear  excepted  and  shall  enlarge  the
         capacity  of the 91st  Avenue  Plant as  required  from tune to time to
         treat  increased  quantities of wastewater  delivered to the plant in a
         manner  and on a  schedule  such  that the  annual  average  DOD of the
         Effluent  from said  plant  shall not  exceed 30 mg/l due to  increased
         flows   through   said  Plant.   Phoenix  may  make   alterations   in,



                                       -16-


<PAGE>

         modifications  to,  replacements , betterments and improve ments of and
         to the 23rd Avenue Plant and the 91st Avenue Plant; provided,  however,
         that the Cities shall at all times carry out their obligations pursuant
         to Section 7.2 hereof.  The Cities further covenant and agree that they
         will not install,  operate and maintain any new sewage  treatment plant
         at any other location if the installation, operation and maintenance of
         such new plant would  impair the ability of the Cities to transfer  and
         deliver  Effluent  pursuant  to this  Agreement.  In  this  connection,
         however,  it is  recognized  that the  long-range  Master  Plan for the
         collection  and treatment of wastewater  from the urban  development in
         the  metropolitan.  area  extends  into  drainage  basins not  normally
         tributary  to the 23rd Avenue or the 91st Avenue  Wastewater  Treatment
         Plants.  New  treatment  facilities  for the Gila and lower  Litchfield
         tributary  basins  are  envisioned,   as  generally  described  in  the
         "Wastewater  Report  for  the  Valley  Metropolitan  Area  of  Phoenix,
         Arizona" by John  Carollo  Engineers,  dated  December,  1968.  Nothing
         herein is intended to impair the  implementation of the Master Plan nor
         to grant  Participants any rights or interests in wastewater  collected
         in the Gila and lower Litchfield  tributary basins, and treated at such
         envisioned  new  facilities.  Prior to the  beginning of each  calendar
         year, the Participants shall submit to the W&S Director in writing, the



                                      -17-


<PAGE>

         estimates of water  requirements  (including  Construction  Water) on a
         daily basis or by month for the ensuing  calendar year.  Such estimates
         will be used  by the W &S  Director  as an  operational  guide  and for
         planning  purposes.  It is understood that Water  Requirements cited in
         Section S of this Agreement are annual quantities only.  Nothing herein
         shall obligate  Phoenix to operate the wastewater  treatment  plants in
         such a manner  as to  process  Effluent  in  uniformly  equal  daily or
         monthly  quantities,  it being  understood that the proper operation of
         the plants is dependent upon the operation of other related  wastewater
         disposal   facilities  and  the  amount  of   non-consumptive   use  of
         water-producing  raw  wastewater  discharged  into the  sanitary  sewer
         system. Like wise, it is understood that the maximum amount of Effluent
         available  for the  Participants'  use is  restricted  to the amount of
         Uncommitted  Effluent which has been processed at the treatment plants.
         The Participant's Facilities located at the 23rd Avenue and 91st Avenue
         Delivery Points shall include metering  devices,  approved by the W & S
         Director and the Operating Agent's  Engineer,  which shall be the basis
         for determining the amount of Effluent sold.

                  7.4 Prior to the effective  date of the exercise of any option
         pursuant to Section 6.2 the W & S Director  and the  Operating  Agent's
         Engineer shall agree upon written practices and procedures  relating to
         processing and delivery of Effluent pursuant to this Section 7, and its
         receipt,   storage  and  transportation  by  the  Participants   during
         Operating Emergencies and Scheduled Outages.

                    7.5 The transfer,  sale and delivery of Effluent by the City
         to the Participants in amounts equal to the Unit 1 Water  Requirements,
         Unit 2 Water Requirements,  Unit 3. Water Requirements and Unit 4 Water
         Requirements;  shall in each case  terminate  and  expire on the Unit 1
         Shutdown Date,  Unit 2 Shutdown  Date,  Unit 3 Shutdown Date and Unit 4
         Shutdown Date,  respectively.  On such dates the amount of the sale and
         purchase of Effluent related to each ANPP Unit shall terminate, without
         further  act of the  Participants.  The  Participants  agree to provide
         Phoenix with at least 24 months' notice of intent of any Shutdown Date.

                    7.6  Nothing  herein  shall be  construed  to  constitute  a
         waiver, relinquishment,  abandonment or forfeiture of any appropriative
         water rights of any of the Cities or any other party hereto.

8.       PAYMENT FOR DELIVERY OF EFFLUENT:

                  8.1 In  consideration  of the  transfer,  sale and delivery of
         Effluent  made by the Cities and the  services to be  performed by them
         pursuant to Section 7 hereof;  the Participants  shall make payments to
         Phoenix in the manner and as determined pursuant to this Section 8.

         at a new location  other than the 23rd Avenue or 91st Avenue  Plants in
         lieu of restoration or  reconstruction of either such plant, the Cities
         shall  transfer,  sell and  deliver  the  same  rights  to the  treated
         wastewater  from  such  substitute  facilities  on the same  terms  and
         conditions as apply to Uncommitted Effluent from the destroyed, damaged
         or condemned plant.

         the price for the  Effluent  shall be  increased  by the amount of such
         tax.

                    17.2 If any general  and/or special city,  county,  state or
         other real  property  taxes,  or any other typical taxes or imposts are

         considered  to  be  in  default  in  the  performance  of  any  of  the
         obligations  hereunder  (other than  obligations of either party to pay

         exercise  of  due  diligence  and  fore-sight   such  party  could  not
         reasonably  have been  expected  to avoid and which by  exercise of due
         diligence it shall be unable to overcome Nothing contained herein shall
         be  construed  so as to  require  either  party to settle any strike or
         labor dispute in which it may be involved. Either party rendered unable
         to fulfill any  obligation by reason of an  uncontrollable  force shall
         exercise due diligence to remove such inability with all reasonable
         dispatch.

1. SOURCE OF WASTEWATER

         The 23rd Avenue and 91st Avenue  Sewage  Treatment  Plants  receive and
treat all wastewater  discharged  into the respective  tributary  sanitary sewer
systems of the  Cities,  which  serve  residential,  commercial  and  industrial
establishments.  Storm water is not  intended to be admitted  into the  sanitary
sewer  Systems but is handled by  separate  storm  sewer  Systems  which are not
tributary to the treatment works.

         The water supply from which the  wastewater  derives,  after being used
for domestic, commercial and industrial purposes, consists of surface water from
the Salt and Verde Rivers and ground water from numerous  wells.  In the future,
Colorado River water may be an added source.

         The strength and  character of  wastewater  entering the Phoenix  sewer
system is regulated by Ordinance.  All  establishments  that produce  wastewater
that  exceeds  the limits set forth in the  Ordinance  are  required to pretreat
their  wastewater  before it is accepted  into the sewer  system.  A copy of the
currently  effective  "Maximum  Allowable  Limits for Discharge into the Phoenix
Sanitary  Sewers  System" - P-S3,  dated  December  22, 1970,  is  attached,  In
addition,  tile  contractual  agreements  between  Phoenix and the other  Cities
involved in the  Multi-City  Sewerage  Plan  include  restrictions  and controls
regarding the strength and character of wastewater  consistent  with the Phoenix
regulations.

2.       QUANTITY OF EFFLUENT

                  Attached is a copy of "Wastewater Flow Projections  1972-2000:
         Estimated Uncommitted Effluent Available, Acre Feet/Year."

3. QUALITY OF EFFLUENT AND METHODS OF ANALYSIS

                    Both the 23rd Avenue and 91st Avenue Sewage Treatment Plants
         are designed and operated, as will be any anticipated future additions,
         to provide secondary treatment for all wastewaters delivered to them by
         the sanitary  sewage  collection  system.  This secondary  treatment is
         presently accomplished at both plants by the activated sludge process.

                    Effluent  quality is based upon and determined at each plant
         by suspended solids and BOD analyses  performed daily on representative
         composite  samples.  The analyses are performed in accordance  with the
         latest  edition of Standard  Methods for the  Examination  of Water and
         Wastewater,   published   jointly  by  the   American   Public   Health
         Association,  American Water Works Association, and the Water Pollution
         Control Federation.

                  The 23rd Avenue and 91st Avenue Sewage Treatment  Plants,  and
         any future  addition  thereto,  will  continue to be operated in such a
         manner that will  produce an  Effluent  that will comply with the Rules
         and Regulations of the Arizona State Department of Health.

                                       E-2



<PAGE>


                  The City shall  exercise  all  reasonable  efforts to operate,
         maintain, enlarge and improve the 23rd Avenue and 91st Avenue Plants in
         a  manner  such  that  the  quality  of the  Effluent  therefrom  to be
         delivered  to  Participants  hereunder  shall  be  compatible  with the
         operation  and  maintenance  of the  Participants'  Effluent  treatment
         facilities  in order that the following  components  of such.  Effluent
         shall  not  exceed  on  an  annual  average  basis  the  concentrations
         indicated below:

               Phosphate                      60 mg/l
               Suspended Solids               30 mg/1
               BOD5                           30 mg/1

         Whenever analyses shall indicate that due to normal or other causes the
         quality of the  Effluent  is in a trend in which it may be  anticipated
         that the above values indicated as annual average concentrations may be
         exceeded  for  extended  periods of time and  whenever any upset in the
         treatment  processes  at either 23rd Avenue or 91st Avenue Plant occurs
         which may result in the  delivery of Effluent  with  concentrations  in
         excess of those listed  above,  for extended  periods of time the W & S
         Director shall cause the Project  Manager's  Engineer or the Operating.
         Agent's Engineer to be promptly notified of such occurrences.


                                       E-3


<PAGE>




  The Cities shall also use their best efforts to regulate  the  discharge  into
  their sewerage  collection  Systems from industrial and commercial  sources of
  any  substances  which would be  detrimental  to the  quality of the  Effluent
  delivered hereunder.

  Participants  shall not be obligated to accept  delivery of, or to pay for any
  inadequately treated Effluent which could not otherwise be lawfully discharged
  in accordance with the Rules and  Regulations of the Arizona State  Department
  of Health or the United States Environmental Protection Agency.

  It is recognized that the Participants'  Facilities require storage reservoirs
  or ponds for purposes of  operational  flexibility  and as a standby source of
  water.  Participants  shall not be obligated to accept  delivery of, or to pay
  for any such inadequately  treated Effluent that cannot be provides sufficient
  dilution by the Participants'  storage ponds to render the Effluent compatible
  with the operation and maintenance of the Participants' treatment facilities.

                    2.4 The adjustment component shall be applied to all Surplus
Effluent sold and delivered  hereunder on or after July 1, 1981, pursuant to the
price  described in Section  2.1(i),  and shall be determined  once each year as
hereinafter set forth.

                         2.4.1 The Base Year shall be 1980.

                         2.4.2 On July 1, 1992,  the  specified  price of $35.00
per acre-foot  shall be adjusted  (increased or  decreased),  based on the final
index for the Base Year and the final  index for the year 1981 by  referring  to
the Index of Implicit Price Deflators for Gross National  Product,  as published
in Table 7.1 of the National  Income and Product  Accounts  Tables of the United
States Department of Commerce  Publication entitled "Survey of Current Business"
(hereinafter "IPD") as applied in the following formula:

                            1981 IPD - 1980 IPD x $35.00
                            -------------------
                                   1980 IPD

          EXAMPLE:
                   Assume  the IPD for the Base  Year  (1980) is 100 and the IPD
                   for 1981 is 110, then the adjustment for the year  commencing
                   July 1, 1982, would be determined as follows:

                             110 - 100 x $35.00= $3.50
                             ---------
                                100

                         2.4.3  Pursuant  to  Section  2.1(i),   the  price  per
acre-foot  thereafter  shall be adjusted  accordingly  for each  successive year
based on the percentage  change in IPD between the final index for the preceding
year and the Base Year.

          EXAMPLE:
                   Assume  the IPD for the Base  Year  (1980) is 100 and the IPD
                   for 1982 is 120, the adjustment for the year  commencing July
                   1, 1983, would be determined as follows:

                            120 - 100 X $35.00 = $7.00
                            ---------
                              100

                         2.4.4 In computing  such adjusted  price per acre-foot,
fractions of a cent will be dropped if less than  one-half (.5) cent and will be
increased to the next higher whole cent if one-half (.5) cent or more.

                         2.4.5 In the event the "IPD" is not  available  for use
in determining the adjustment  component in July of 1982 or any subsequent year,
the  adjustment  component  shall  be  held in  abeyance  for  Surplus  Effluent
delivered  in such year until such index is  available,  at which time  Tolleson
shall  determine the adjusted  price  pursuant to Section  2.1(i),  and, if such
price is  applicable  for any year in question,  shall  submit,  and APS and SRP
shall pay, an adjusted  invoice  applying the proper  adjustment  to all surplus
Effluent previously delivered in such year.

                         2.4.6 In the event the IPO  shall be  discontinued,  an
appropriate  index  will be  substituted  therefor  by mutual  agreement  of the
parties.

Section 9.     Force Majeure.

                  9.1 Neither Tolleson nor APS and SRP shall be considered to be
in default in the performance of any of the obligations  hereunder if failure of
performance  shall be due to an uncontrollable  force. The term  "uncontrollable
force" shall mean any cause beyond the control of the party affected, including,
but not limited to, failure of facilities,  flood,  earthquake,  tornado, storm,
fire, lightning,  epidemic, war, riot, civil disturbance or disobedience,  labor
dispute,  and  action  or  nonaction  by or  failure  to  obtain  the  necessary
authorizations  or approvals  from any  governmental  agency or authority or the
electorate, labor or material shortage, sabotage and restraint by Court order or
public  authority,  which by exercise of due diligence and foresight  such party
could not  reasonably  have been  expected to avoid and which by exercise of due
diligence  it shall be unable to  overcome.  Nothing  contained  herein shall be
construed so as to require either party to settle any strike or labor dispute in
which it may be involved. Either party rendered unable to fulfill any obligation
by reason of any  uncontrollable  force shall  exercise due  diligence to remove
such inability with all reasonable dispatch.

                  9.2  Whenever  uncontrollable  force as defined in Section 9.1
prevents APS and SRP from being able to accept or use the Surplus Effluent, then
Tolleson may enter into  temporary  contracts with any other parties for sale of
the Surplus  Effluent.  It Tolleson  has entered into such  temporary  contract,
Tolleson  shall  be  allowed  up to 30 days to  begin  delivery  of the  Surplus
Effluent to APS and SUP after receiving written notice from APS and SRP that the
disability has been removed.

                  9.3  Notwithstanding  the  provisions of Sections 9.1 and 9.2,
if, after the exercise of due diligence, the party rendered unable to fulfill an
obligation  remains unable to remove such inability for one full year, the other
party may elect to terminate  the Agreement  anytime  thereafter by tendering 90

Section 10. Interruption of Delivery of Surplus Effluent.

           Tolleson shall have the right to refuse to deliver  Surplus  Effluent
or any portion of it under the terms of Agreement when the following occurs:

           (a) There exists in Tolleson a critical need for water to be used for
      domestic purposes;

           (b) All other reasonable sources of water have been exhausted;

           (c) Reasonable  steps have been taken to conserve the water supply in
      Tblleson; and

           (d) Reasonable  notice of the critical need has been given to APS and
      SRP.

terms of this Agreement.  Tolleson shall use its best efforts to resume delivery
of Surplus Effluent  hereunder at the earliest  practical time in the event such
deliveries are interrupted in accordance with this Section 10.

Section 11.  Affect of Outage or Malfunction on Acceptance of Effluent.

                  11.1 In the event that a nonscheduled  outage  ("nonscheduled"
outage meaning an outage occurring due to reasons outside the control of APS and
SRP),  or  malfunction  of any  component  or system of the Palo Verde  Effluent
Pipeline  or the WRF at the Palo Verde  Station,  restricts  the  capability  of
either of such  facilities  to transport or treat  wastewater  effluent from all
sources,  then APS and SRP may refuse to accept delivery of the Surplus Effluent
and shall not be required to pay therefor It us  understood,  however,  that the
Surplus Effluent from Tolleson's Plant shall be the last source of effluent that
APS and SR? cut back on during such outage and that APS and SRP shall not refuse
to accept and pay for  Tolleson's  Surplus  Effluent to the extent that they are
accepting and paying for effluent from any other source. Further, a nonscheduled
outage  which cuts off or cuts back on the amount of Surplus  Effluent  accepted
and paid for by APS and SRP shall be  treated  as an  "uncontrollable  force" as
defined in Section g of this  Agreement and shall be governed by the  provisions
of Section 9.

                  11.2 In the event that an outage as  described in Section 11.1
is a scheduled outage  ("scheduled" outage meaning an outage that is planned and
controlled  by APS and SRP),  APS and SRP shall  continue to pay for the Surplus

Effluent that would have been delivered  during any scheduled  outage lasting up
to one year in length.  Should the scheduled  outage  continue for more than one
year,  from that point in time,  APS and SRP shall pay  one-half  the price that
they otherwise would have paid for any Surplus  Effluent they do not accept.  At
any time that a scheduled outage continues for more than two years, Tolleson may
in its sole  discretion  elect to  terminate  the  Agreement  by  giving 90 days
written notice to APS and SRP.

                  11.3  Except in  emergencies,  APS and SRP shall  give 90 days
written  notice in  advance  of any  discontinuation  of  acceptance  of Surplus
Effluent under the provision of this Section.
