                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


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


We have reviewed the accompanying condensed consolidated balance sheet of Public
Service Company of New Mexico (a New Mexico  corporation) and subsidiaries as of
March 31, 1997, and the related  condensed  consolidated  statements of earnings
for the  three-month  periods  ended March 31, 1997 and 1996,  and the condensed
consolidated  statements of cash flows for the  three-month  periods ended March
31, 1997 and 1996.  These  financial  statements are the  responsibility  of the
company's management.

We conducted our review in accordance with standards established by the American
Institute  of  Certified  Public  Accountants.  A review  of  interim  financial
information consists principally of applying analytical  procedures to financial
data and making  inquiries of persons  responsible  for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with  generally  accepted  auditing  standards,  the  objective  of which is the
expression of an opinion  regarding the financial  statements  taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material  modifications that should
be  made  to the  financial  statements  referred  to  above  for  them to be in
conformity with generally accepted accounting principles.

We have  previously  audited,  in accordance  with generally  accepted  auditing
standards,  the  consolidated  balance  sheet of Public  Service  Company of New
Mexico and subsidiaries as of December 31, 1996 (not presented herein),  and, in
our report dated February 13, 1997, we expressed an unqualified  opinion on that
statement.  In our  opinion,  the  information  set  forth  in the  accompanying
condensed  consolidated balance sheet as of December 31, 1996, is fairly stated,
in all material  respects,  in relation to the  consolidated  balance sheet from
which it has been derived.

              PUBLIC SERVICE COMPANY OF NEW MEXICO AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1)    General Accounting Policy

In the opinion of management,  the accompanying unaudited consolidated financial
statements  contain all  adjustments  necessary for a fair  presentation  of the
consolidated financial statements.  The significant accounting policies followed
by Public  Service  Company of New Mexico (the  "Company") are set forth in note
(1) of notes to the Company's consolidated financial statements in the Company's
Annual Report on Form 10-K for the year ended  December 31, 1996 (the "1996 Form
10-K") filed with the Securities and Exchange Commission ("SEC").

(2)     Nuclear Decommissioning Costs

The  Company's  share of the Palo Verde  Nuclear  Generating  Station  ("PVNGS")
decommissioning  costs will be approximately $147.5 million in 1995 dollars. The
Company  makes  regular  payments  under  agreements  approved by the New Mexico
Public Utility Commission  ("NMPUC") to external tax qualified and non-qualified
trusts  over  the  estimated  useful  life  of  each  unit.  A  portion  of  the
non-qualified trust funds are invested in life insurance policies. The remaining
trust funds are  invested  primarily in  equities,  a municipal  bond fund and a
money market fund. Decommissioning costs are charged to expense over the license
term and  decommissioning  costs for Units 1 and 2 are  currently  recovered  in
rates. As of March 31, 1997, the nuclear  decommissioning  trusts had net assets
of $25.6 million.

(3)     Refinancing

On February 21, 1997, the Company  completed the  refinancing of $190 million of
pollution  control revenue bonds issued by the City of Farmington,  all maturing
in April 2022. The $60 million 1978 Series A Pollution Control Revenue Bonds and
the $40 million 1979 Series A Pollution Control Revenue Bonds were refinanced as
variable rate bonds (Pollution Control Revenue Refunding Bonds, $40 million 1997
Series A, $37 million  1997 Series B and $23 million 1997 Series C). The initial
variable  rates were 3.35% for $40 million  1997  Series A and $37 million  1997
Series B, and 3.30% for $23  million  1997 Series C. The  remaining  $90 million
1979 Series A Pollution  Control Revenue Bonds were refinanced with a fixed rate
of 6.375% (Pollution Control Revenue Refunding Bonds, 1997 Series D).

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
   AND RESULTS OF OPERATIONS

The Company's  1996 Form 10-K PART II, ITEM 7. --  "MANAGEMENT'S  DISCUSSION AND
ANALYSIS  OF  FINANCIAL   CONDITION   AND  RESULTS  OF   OPERATIONS"   discussed
management's  assessment  of  the  Company's  financial  condition,  results  of
operations  and other issues facing the Company.  The following  discussion  and
analysis by management  focuses on those  factors that had a material  effect on
the Company's  financial  condition  and results of operations  during the first
quarter of 1997 and 1996.  It should be read in  conjunction  with the Company's
consolidated financial statements. Trends and contingencies of a material nature
are discussed to the extent known and considered relevant.

                         LIQUIDITY AND CAPITAL RESOURCES

The capital requirements for 1997 including a retrofit  environmental project at
the San Juan  Generating  Station,  purchases  of PVNGS Lease  Obligation  Bonds
("LOBs") and cash dividend  requirements for both common and preferred stock are
expected to be $214.4 million. The Company spent approximately $30.5 million for
its utility construction expenditures and dividend requirements during the first
quarter of 1997 and anticipates  spending  approximately $184 million during the
remainder of 1997. The Company  expects that such cash  requirements  can be met
primarily through internally  generated cash.  However, to cover the differences
in the amounts and timing of cash generation and cash requirements,  the Company
intends to utilize short-term  borrowings under its liquidity  arrangements.  At
March 31, 1997,  the Company had $100 million of short-term  borrowings  against
its liquidity  arrangements and had $111 million in unused  liquidity  capacity.
Included in this  capacity were $100 million  under a secured  revolving  credit
facility  ("Facility") and $11 million under local lines of credit. The Facility
will expire in June 1998 and the Company  expects to renew the  Facility  before
its expiration date.

On February 21, 1997, the Company  completed the  refinancing of $190 million of
pollution  control revenue bonds issued by the City of Farmington,  all maturing
in April 2022 (see Note 3 of Notes to Financial Statements).

As of March 31, 1997, the Company had  approximately  $20.5 million in temporary
investments.   The  Company  continues  to  evaluate  its  investment  and  debt
retirement options to optimize its financing strategy and earnings potential.

Dividends

On March 12,  1997,  the  Company's  board of  directors  ("Board")  declared  a
quarterly  cash dividend of 17 cents per common share,  payable May 23, 1997, to
the common  stockholders  of record as of May 12, 1996. This is an increase of 5
cents per share above the dividend paid in the prior quarter and  represents the
first increase since the  reinstatement of the common stock dividend a year ago.
The Company's Board 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.

                                      -8-
<PAGE>


                              RESULTS OF OPERATIONS

Net earnings  applicable to common stock decreased $1.6 million ($.04 per share)
for the quarter ended March 31, 1997, from the corresponding period last year.

The following discussion highlights significant items which affected the results
of operations for the quarter ended March 31, 1997 and 1996.

Electric gross margin (electric operating revenues less fuel and purchased power
expense) for the current  quarter  increased $1.8 million from a year ago due to
increased off-system sales. Higher gas prices on the West Coast and transmission
limitations from the Northwest to the  California-Arizona  market contributed to
the increase in off-system sales.

Gas gross margin (gas operating  revenues less gas purchased for resale) for the
current  quarter  decreased  $1.0 million  from the  previous  year due to lower
off-system  sales.  Off-system  sales margin  decreased by $2.0 million from the
corresponding  period a year ago  because of lower price  differentials  between
market hubs.

Other operation and maintenance  expenses increased $3.6 million for the quarter
over the same  period  last year.  An  adjustment  of $3.4  million  had reduced
retirees' health care costs in 1996. In 1997,  compensation expense recorded for
the exercise of employee stock options (one-time item) increased  administrative
and general  labor  expense by $3.8  million.  That increase was offset by lower
electric  production  expense of $3.4  million as a result of reduced  scheduled
maintenance outages in the current quarter.

Other income and deductions,  net of taxes, for the quarter ended March 31, 1997
increased $1.6 million from the corresponding period a year ago due to increased
interest  income  resulting from the purchase of $200 million of LOBs in October
of 1996.

Net interest charges increased $1.4 million for the quarter ended March 31, 1997
from the  corresponding  period a year ago as a result of  increased  short-term
borrowings related to the purchase of the $200 million of LOBs.

                         OTHER ISSUES FACING THE COMPANY

Gas Rate Case

As previously reported,  on February 13, 1997, the NMPUC issued a final order in
the gas rate case,  ordering a rate decrease of approximately  $6.9 million.  In
the order,  the NMPUC  disallowed,  among other things,  the recovery of certain
regulatory  assets.  The Company had requested a $13.3  million  increase in its
retail  natural  gas  sales  and  transportation  rates.  The  Company  strongly
disagrees  with the NMPUC's  final  order and has  appealed it to the New Mexico
Supreme Court. (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" in the 1996 Form 10-K.)

                                      -9-
<PAGE>

The New Mexico Attorney  General ("AG") filed a notice of appeal of the gas rate
case on March 17,  1997.  On March  21,  1997,  the  Company  filed a  docketing
statement on the appeal of the $6.9 million gas rate  reduction  order.  This is
the second  step in the  appeal  process  following  the filing of the appeal in
February 1997. The docketing statement identifies all of the errors in the final
order that the  Company  may raise in its  appeal,  which  include,  among other
things,  (i) disallowance of loss on reacquired debt and reservation  fees, (ii)
transportation discount amounts, (iii) a reliability cost surcharge on sales and
transportation  customers,  (iv) cost of capital issues, (v) the NMPUC's refusal
to hear a  proposed  settlement  of the case  stipulated  among  the  interested
parties  and  (vi)  the  cumulative  error  of the  order.  The AG also  filed a
docketing  statement on April 16, 1997,  challenging the NMPUC's rate design and
refusal to implement the reliability cost surcharge on sales and  transportation
customers.  The appeal will continue with the filing of  briefs-in-chief  by the
Company and the AG on June 11, 1997, response briefs by participants in the case
on August 29, 1997,  reply briefs by all participants on September 22, 1997, and
oral  argument  before the  Supreme  Court at an as-yet  unspecified  date.  The
Company is unable to predict the date that the Supreme  Court will  subsequently
issue its decision. While the appeal is pending, the NMPUC's final order remains
in effect.

NMPUC Order on the Cost of Gas Case

As previously reported,  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  gas cost factor  calculations  for the period of  December  1995
through  January  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 NMPUC also ordered the
docketing of two new investigations.  The first, which required a Company filing
by March 15, 1997, will investigate whether the Company should exit the merchant
function.  The merchant  function  refers to the Company's  purchase and sale of
natural gas for its sales 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.
The Company strongly  disagrees with the NMPUC's final order. (See PART II, ITEM
7. -- "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS
OF OPERATIONS -- OTHER ISSUES FACING THE COMPANY -- NMPUC ORDER -- THE COMPANY'S
JANUARY 1997 PGAC FACTOR VARIANCE REQUEST; ORDER TO FILE NEW RETAIL ELECTRIC AND
GAS RATE CASES" in the 1996 Form 10-K.)

On March 5, 1997,  the NMPUC,  noting that the  Company had by letter  indicated
that it  might  request  a  rehearing,  entered,  on its own  motion,  an  order
reopening the  proceeding  to, among other  things,  take  additional  testimony
regarding  the  allegedly   incorrect  gas  cost  factor.  The  reopening  order
specifically  left all of the findings and  conclusions in the February 13 order
in place,  but ruled that the  February  13 order was now an  interim  order and
established  a  procedural  schedule  for  the  Company  to  present  additional
testimony and for  additional  hearings.  On March 14, 1997, the Company filed a
motion for  rehearing  of the  reopening  order asking the NMPUC to withdraw the
February 13 order and enter a new final order.

                                      -10-

On April 2, 1997,  the NMPUC issued an order,  partially  granting the Company's
rehearing motion and agreeing to withdraw and vacate portions of the February 13
order.  In the April 2 order,  the NMPUC (1) withdrew the finding that,  because
the veracity of the  Company's  filings have been  brought into  question,  rate
cases for both gas and  electric  operations  were  necessary,  (2) withdrew the
requirement  that the Company must pay for an independent  audit of its gas cost
filings,  (3) suspended the imposition of the $2.2 million civil penalty and the
order prohibiting the Company from recovering $1.6 million in gas costs incurred
in December 1996, and (4) reaffirmed the March 5 order  reopening the proceeding
for  additional  testimony.  That  testimony  from the Company is due on May 19,
1997,  and further  hearings  are  scheduled  for June 23,  1997.  The Board has
established  an ad  hoc  committee  of  outside  directors  to  investigate  the
assertions  of  misconduct  made by the  NMPUC in its  February  13  order.  The
committee has retained  independent counsel to assist in the investigation.  The
investigation is expected to be completed by the time Company testimony is due.

In the April 2 order, the NMPUC further found that, because of the rapid changes
occurring in the electric industry, all major electricity suppliers,  within the
jurisdiction of the NMPUC,  which have not adopted a plan to provide retail open
access must make a general  rate case  filing with the NMPUC.  The April 2 order
additionally requires the electric operations to make a general rate case filing
by June 2, 1997.  The status of the  electric  rate case filing  requirement  is
discussed below.

Filings Relating to Electric Rate Case and Electric Industry Restructuring

On April 24, 1997,  the Company  filed  related  motions in two  separate  cases
before the NMPUC:  Case No. 2681,  the NMPUC's  Notice of Inquiry into  electric
industry  restructuring  and Case No. 2761,  the  Company's  electric  rate case
filing ordered by the NMPUC.  The Company  proposes that the NMPUC reconvene the
Case No. 2681  proceedings  in an attempt to arrive at consensus  legislation to
present to the 1998 session of the New Mexico  Legislature.  In its filing,  the
Company  offers to pay for an expert  facilitator  or  mediator  selected by the
NMPUC to drive the process towards consensus. However, the Company's proposal is
conditioned  on the  NMPUC  granting  the  motion  in Case No.  2761 to stay all
proceedings and vacate the existing  requirements to file a rate case by June 2,
1997, together with unbundled tariffs.  The Company contends that all interested
parties   should  focus  their   efforts  on  reaching   consensus  on  industry
restructuring  for the 1998  legislative  session  and points out that the NMPUC
will be replaced by the Public Regulation Commission ("PRC") on January 1, 1999.
The Company also contends that the NMPUC's order  requiring the rate case is for
the unlawful  purpose of forcing retail  competition  since the NMPUC lacks such
authority,  and that the  Company's  due  process  rights  are  violated  by the
requirement to file a rate case in the time frame specified and because the lack
of a retail  competition market structure makes it impossible to properly design
unbundled  tariffs.  The  Company  stated that it was  prepared to litigate  the
matter if its  proposal  to settle  differences  is not  adopted  by May 5, 1997
unless the NMPUC grants an initial extension to file the rate case to June 30 to
allow more time to consider the proposal. On April 28, 1997, the NMPUC issued an
order  scheduling  a hearing in Case No.  2681.  The order stated that the NMPUC
should not rule on the two motions until it has a complete  understanding of the
Company's  proposal in both motions and, more  importantly,  the  opportunity to
assess the likelihood  that the  collaborative  efforts  proposed by the Company
will succeed.

On May 6, 1997, the NMPUC issued an order,  accepting the Company's  proposal on
the  collaborative  efforts  intended to introduce  competition into the state's
retail  electric power market.  In the order,  the NMPUC agreed to the Company's
proposal  for a series of meetings  including  all  interested  parties to draft
legislation for  consideration by the New Mexico  Legislature in 1998. The NMPUC
suspended its earlier order  requiring the Company to file an electric rate case
in June  1997 to  facilitate  the  collaborative  process.  However,  the  NMPUC
indicated  that it will  order  the  Company  to file an  electric  rate case by
September 1, 1997, if the parties in the negotiation  fail to reach consensus on
an industry  restructuring plan by August 1, 1997. If the collaborative  process
terminates  without  consensus  prior to August 1, the NMPUC  will  require  the
Company to file an electric  rate case no later than thirty days after  issuance
of an order finding that the process has been  terminated.  The  participants in
the   collaborative   process  must  file  a  plan  outlining  the  process  and
establishing the filing date for their  restructuring  proposals with the NMPUC.
In the order,  the NMPUC also outlined three subjects which must be addressed in
the  collaborative  efforts,  including (i) financial and economic issues,  (ii)
consumer protection and environmental  issues and (iii) timing of the transition
to a competitive market.

Filing Relating to Termination of Gas Merchant Function

As noted above,  included in the February 13 order in the cost of gas case,  the
NMPUC  ordered the Company to make a separate  filing  addressing  the terms and
conditions under which the Company would consider exiting the merchant  function
and to identify any compelling issues that should be brought to the attention of
the NMPUC  relating to exiting the merchant  function.  Since the cost of gas is
passed through to customers,  the Company does not make a profit or loss on this
service.

On March 31, 1997, the Company filed its response in NMPUC Case No. 2760. In the
filing, the Company asserted that all customers should have the option to choose
their natural gas supplier, advocating that, ultimately,  customer choice should
dictate  whether the  Company's  gas  operation  retains its merchant  function.
Currently,  all customers may choose to become  transportation  customers on the
Company's  distribution  system,  but  nearly  all  residential  and most  small
commercial customers receive bundled sales service. The Company also outlined in
the filing that, in addition to continuing to provide customers with information
on their current  options,  it will conduct a customer survey to determine their
awareness of the choices and preferences of services provided by the Company and
other suppliers.  As stated in the filing,  the Company is currently planning to
file by May 16, 1997 a proposal with the NMPUC,  outlining immediate measures to
facilitate  the  choice  of  transportation  service  by  small  commercial  and
residential  customers  to be in  place by next  winter.  By June 1,  1997,  the
Company will also form a working group, consisting of customers, regulators, the
AG staff, the Company and gas marketers, to determine what is needed to increase
competition  and more fully  develop  supplier  choice for sales  customers.  In
addition, the Company apprised the NMPUC of its intent to file for approval of a
defined  target  purchased  gas  adjustment  clause  (similar  to  an  incentive
mechanism) by September 1, 1997, to be in effect by the winter of 1998/1999.

Investigation of Gas Supply Procurement Practices

As noted above,  included in the February 13 order in the cost of gas case,  the
NMPUC  established a docket in NMPUC Case No. 2759 to review the gas procurement
practices and policies of the Company's gas  operations.  On April 14, 1997, the
Company filed  testimony  supporting the prudence of its practices and policies.
The Company asserted that its procurement  practices and policies were conducted
in  accordance  with  the  rules  and  regulations  of the  NMPUC  and  industry
standards,  and all gas  costs  billed to  customers  were  prudently  incurred.
Hearings on the review are currently scheduled to commence on May 27, 1997.

Chihuahua, Mexico Project

As previously  reported,  in January 1997, the Company had submitted a joint bid
to  develop,  design,  construct,  manage and operate  natural gas  distribution
systems in the cities of Chihuahua  and  Cuauhtemoc-Anahuac  and Delicias in the
State of Chihuahua,  Mexico.  (See PART II, ITEM 7, -- "MANAGEMENT'S  DISCUSSION
AND ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF  OPERATIONS  -- OVERVIEW --
Competitive  Strategy"  in the 1996 Form  10-K.) In January  1997,  the  Mexican
authority  determined  that the  Company's  joint bid did not pass the technical
review and awarded  the project to another  company.  The Company  continues  to
explore  and  identify  opportunities  to  provide  energy and  utility  related
services and pursue new business opportunities in Mexico.

Update  Regarding  1997  State  Legislative  Session  Activities  Affecting  the
Electric Utility Industry in New Mexico

The 1997 New Mexico legislative  session adjourned on March 22, 1997. Two retail
wheeling bills were  introduced but both died on adjournment  after being tabled
in the first committee.

Two joint  memorials  passed both chambers.  One continues an interim  committee
study of industry restructuring. The second directs a study on the tax impact on
any restructuring and alternative tax structures to preserve the state and local
revenue base. Gubernatorial action is not required.

A bill to create an interim  committee to study  transition to the new PRC which
will become  effective  January 1, 1999,  passed but was vetoed by the Governor.
The  Legislative  Council can establish such a committee on its own or add those
duties  to an  existing  interim  committee.  A bill  that  sets  forth the five
districts  for the new PRC  commissioners  was passed and signed into law by the
Governor. It is likely that legislation  empowering the PRC will be discussed in
an interim committee and will be enacted during the 30-day 1998 session.

The  Governor  signed a bill  authorizing  the City of Las Cruces to condemn the
utility  system owned by El Paso  Electric  Company that serves Las Cruces,  New
Mexico; however, the new law is limited only to the City of Las Cruces.

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.

New Mexico Industrial Energy Consumers ("NMIEC")

On April 22, 1997,  NMIEC filed a petition for declaratory  order with NMPUC. In
its  petition,  NMIEC states that the Company has  interrupted  service to NMIEC
members taking service under the Experimental  Incremental  Interruptible  Power
Rate ("EIIPR") during off-peak periods and such interruptions  violate the terms
of the EIIPR. The  interruptions  resulted from a scheduled  maintenance for the
Company's 345 Kv line connected to the Four Corners  Generating  Station.  NMIEC
alleges that its members have  suffered  economic harm from losses in production
due to such  interruptions.  The  petition  requests,  among other  things,  (i)
clarification  over the EIIPR to determine that EIIPR  customers are entitled to
be treated the same as all other customers with similar  consumption when system
emergency  curtailments occur during the off-peak hours; (ii) determination that
the Company's  practice of interrupting EIIPR customers during off-peak hours is
discriminatory;   and  (iii)  the  Company  to  discontinue   such  practice  of
interrupting  EIIPR  customers.  The  Company  is  currently  investigating  the
complaint filed by NMIEC.

PART II -- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

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

As  previously  reported,  in April 1993,  the  Company and certain  current and
former  employees  of the Company or Meadows  Resources,  Inc.,  a  wholly-owned
subsidiary of the Company ("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  related to alleged  actions of the  Company's or
Meadows'  employees  in 1987 in  connection  with a loan  procured  by  Bellamah
Community  Development  ("BCD"),  whose general partners  include Meadows,  from
Western and the purchase by that  partnership of property owned by Western.  The
FDIC (the FDIC was  substituted  for the RTC as  plaintiff  in  MDL-995 in early
1996) 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 FDIC 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 FDIC claims that  damages  under the Arizona  racketeering  statute
would be trebled under  applicable  law. The  prevailing  parties on the Arizona
racketeering  claims  could  seek fees and  costs  from the  parties  who do not
prevail.

In  April  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.  (See  PART I,  ITEM  3.  --  "LEGAL
PROCEEDINGS -- OTHER PROCEEDINGS" in the 1996 Form 10-K.)

Settlement documents are still being prepared.  Delays have occurred due in part
to  reassignment  of attorneys for the FDIC but  submission  for court  approval
appears  imminent.  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.

PVNGS Property Taxes

As  previously  reported,  in April  1996,  the PVNGS  participants  and Arizona
Department of Revenue  reached an agreement to settle the  litigation  which was
pursued by the PVNGS  participants,  claiming  that  portions of the new tax law
enacted in 1990 are  unconstitutional.  The  Arizona  Court of Appeals  ruled in
favor of the  participants  in 1995.  As a result,  in July 1996, a $200 million
property tax reduction was enacted which  codifies the terms of the  settlement.
(See PART I, ITEM 3. -- "LEGAL  PROCEEDINGS -- PVNGS PROPERTY TAXES" in the 1996
Form 10-K.) On February  11, 1997,  the parties to this action  signed the final
documents,  resulting in a reduction to the Company's  Arizona property taxes by
approximately  $4.0 million  annually  beginning in 1996 and  extending at least
three years, barring any subsequent changes in the applicable tax laws. Pursuant
to the  settlement,  the Company is required to 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 after 1995.

DISCUSSION  -- OTHER  ISSUES -- Gas Rate Case and  Filings  Relating to Electric
Rate Case and Electric Industry Restructuring".

ITEM 5.  OTHER INFORMATION

Independent System Operator ("ISO")

On March 14, 1997, the Company entered into a Memorandum of  Understanding  with
other transmission service providers to investigate the feasibility and benefits
of forming an ISO in the Southwest.  Entities participating in the investigation
process include the Company, Arizona Electric Power Cooperative,  Arizona Public
Power Company ("APS"),  El Paso Electric Company,  Nevada Power Company,  Plains
Electric Generation & Transmission  Cooperative,  Salt River Project,  Texas-New
Mexico Power Company,  Tucson  Electric  Power Company and the Desert  Southwest
Region of the  Western  Area Power  Administration.  Federal  Energy  Regulatory
Commission  Order 888, issued in 1996,  encourages  utilities to investigate the
formation  of such  ISOs  and  provides  criteria  under  which  the  formation,
operation and governance of ISOs would be reviewed.

The  proposed  ISO,  named the Desert  Southwest  Transmission  and  Reliability
Operator ("Desert STAR"), would be empowered to serve as a transmission security
monitor,   handle  transmission  service   reservations,   transmission  service
scheduling and accounting, manage relief of congestion of the transmission grid,
procure  ancillary  services  required for  transmission  system  operation  and
operate a grid-wide Open Access Same-time  Information System. Desert STAR would
be governed by an independent board representing all industry customer sectors.

The  feasibility  study group has held five public  forums to receive input from
interested  entities regarding the formation of an ISO. The participants  expect
that a six month investigation would result in a completed feasibility study for
Desert STAR.  Implementation  of the  feasibility  study would  require  various
regulatory  approvals  at both the state  and  Federal  level.  The  Company  is
currently  unable to predict the timing of the formation or the ultimate outcome
of the proposed ISO.

Four Corners Generating Station ("Four Corners")

Four Corners is located on land held under easements from the Federal government
and also under leases from the Navajo Nation.  APS is the operating agent of the
plant and the Company owns a 13% ownership  interest in Units 4 and 5. The lease
for Four Corners  contains a waiver until 2001 of the  requirement  that APS pay
certain  taxes to the Navajo  Nation.  APS and the Navajo  Nation are  currently
attempting to negotiate an agreement that would settle certain issues  regarding
this waiver and other matters, including the computation of royalties due on the
sales of coal and  possessory  interest  taxes  paid by the  Four  Corners  coal
supplier. The Company is currently unable to predict the outcome of this matter.

Person Station

The Company, in compliance with the New Mexico Environment Department's ("NMED")
Corrective Action Directive, determined that groundwater contamination exists in
the deep and shallow  water  aquifers at its  retired  fossil-fueled  generating
station.  The Company is required to delineate  the extent of the  contamination
and remediate the contaminants in the groundwater. The extent of the contaminant
plume in the deep water  aquifer was assessed  and results were  reported to the
NMED.  The  Company  estimated  approximately  $10.9  million  to  complete  the
groundwater  remediation  program at Person  Station.  (See PART II,  ITEM 7. --
"MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS  -- OTHER  ISSUES  FACING  THE  COMPANY  --  ENVIRONMENTAL  ISSUES --
Electric Operations -- Person Station" in the 1996 Form 10-K.)

Based on currently  available  information,  the Company's  revised estimate for
completion of the groundwater remediation program is approximately $6.3 million,
a reduction of $4.6 million from the previously  reported estimate.  As required
by regulation, the Company maintains a post-closure trust fund with a trustee to
demonstrate financial assurance for post closure activities. The current balance
of the  trust  fund is  approximately  $6.8  million.  The  remediation  program
continues on schedule.

Organizational Change

Effective  March 11,  1997,  the  Company's  Board  elected  Mr.  Jeff Sterba as
Executive Vice President and Chief Operating Officer,  reporting directly to the
President and Chief  Executive  Officer.  Mr. Sterba will focus his attention on
the operational  side of the Company,  overseeing the electric,  gas, energy and
bulk power  services  business  units.  This change  will  enable the  Company's
President to focus on industry  restructuring and building better  relationships
with  regulatory  and  legislative  leaders  and  customers  to be a  successful
competitor in the new energy marketplace.

irrespective  of whether  or not the Bank  shall have made any demand  hereunder
although such obligations may be contingent or unmatured.

         SECTION 23.  Indemnification.  In  consideration  of the  execution and
delivery  of  this  Agreement  by the  Bank,  the  Company  hereby  indemnifies,
exonerates and holds the Bank and each of its officers, directors, employees and

against any and all actions, causes of action, suits, losses, costs, liabilities
and damages,  and expenses  incurred in connection  therewith  (irrespective  of
whether  any  such  Indemnified  Party  is a  party  to  the  action  for  which
indemnification  hereunder is sought),  including reasonable attorneys' fees and
disbursements  (collectively,  the "Indemnified  Liabilities"),  incurred by the

         statement of any material fact contained or  incorporated  by reference
         in the  Preliminary  Official  Statement  (other  than  in  Appendix  B
         thereto)  or in the  Official  Statement  (other  than  in  Appendix  B
         thereto),  or in any amendment,  modification or supplement thereto, or
         the omission to state  therein a material  fact  necessary to make such
         statements,  in the light of the circumstances  under which they are or
         were made, not misleading;

                  (d)any investigation,  litigation or proceeding related to any
         Environmental  Law, any  environmental  cleanup,  audit,  compliance or
         other  matter  relating to the  protection  of the  environment  or the
         Release by the  Company  or any of its  Subsidiaries  of any  Hazardous

                  (e)the presence on or under, or the escape, seepage,  leakage,
         spillage, discharge,  emission,  discharging or releases from, any real
         property owned or operated by the Company or any Subsidiary  thereof of
         any Hazardous  Material  (including any losses,  liabilities,  damages,
         injuries,  costs,  expenses  or claims  asserted  or arising  under any
         Environmental  Law),  regardless  of  whether  caused by, or within the
         control of, the Company or such Subsidiary,

except  for any  such  Indemnified  Liabilities  arising  for the  account  of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence  or willful  misconduct,  and if and to the extent that the foregoing
undertaking may be  unenforceable  for any reason,  the Company hereby agrees to
make the maximum  contribution  to the payment and  satisfaction  of each of the
Indemnified Liabilities which is permissible under applicable law.

         SECTION  24.  Survival.  The  obligations  of the  Company  under  this
Agreement  shall  continue until the later of the  Termination  Date or the date
upon which all  amounts  due or to become due to the Bank  hereunder  shall have
been  paid in full;  provided,  however,  that the  obligations  of the  Company
pursuant to Section 23 and  Section 28 shall  survive  the  termination  of this
Agreement.

         SECTION 25. Transfer of the Letter of Credit.  The Letter of Credit may
be transferred in accordance with the provisions set forth therein.

         SECTION 26. Confirmation of Lien; Trust.

         (a) The Company  hereby  grants to the Bank,  to secure  payment by the
Company of sums due hereunder, a lien on moneys or instruments (at such times as
they become payable to the Company under the Ordinance) which the Company has an
interest in or title to pursuant to the Ordinance,  now or hereafter held by the
Trustee  under the Ordinance and in the right of the Company to receive any such
moneys or instruments.

         (b) The Bank  agrees  to hold  the  proceeds  of any  lien or  security
interest  referred to in clause (a) or to take or receive any collateral  (other
than the Pledged  Bonds) as security for the  Company's  obligations  under this
Agreement,  in each case in trust for the equal and pro rata  benefit of itself,
on the one hand,  and the holders of the Bonds,  on the other hand. No holder of
any Bond nor the Trustee may  exercise  any rights  under the trust  established
pursuant  to this  clause (b) unless and until the  Trustee  has drawn under the
Letter of Credit  pursuant to the Ordinance,  and then only to the extent that a
strictly  conforming  draft  has  not  been  honored  by  the  Bank.  Any  right
established  hereunder  for the benefit of any holder of any Bond shall:  (i) be
released,  without any consent, waiver, notice or other action by such party, in
the amount  and to the extent of the  satisfaction  of the  obligations  due the
holders of any Bond or to the extent of any payment to the Trustee pursuant to a
Drawing  under the Letter of Credit and (ii)  terminate if (A) such  termination
would not lead to the Bank  being  released,  prevented  or  restrained  from or
delayed  in  fulfilling  its  obligations  under the Letter of Credit or (B) the
absence of the  agreement  contained  in this clause (b) would not result in the
lowering or suspension by S&P or Moody's of its rating of the Bonds.

         SECTION 27.  Limited  Liability  of the Bank.  The Company  assumes all
risks of the acts or omissions of the Trustee and any  transferee  of the Letter
of Credit with respect to its use of the Letter of Credit.  Neither the Bank nor
any of its officers or directors  shall be liable or responsible for (a) the use
which may be made of the  Letter of Credit or for any acts or  omissions  of the
Trustee and any  beneficiary  or  transferee in  connection  therewith;  (b) the
validity, or genuineness of documents, or of any endorsement(s) thereon, even if
such  documents  should  in fact  prove  to be in any or all  respects  invalid,
fraudulent  or forged;  or (c) any other  circumstances  whatsoever in making or
failing to make payment under the Letter of Credit, except only that the Company
shall  have a claim  against  the  Bank,  and the Bank  shall be  liable  to the
Company,  to the extent,  but only to the extent,  of any direct,  as opposed to
consequential,  damages  suffered by the Company  which the Company  proves were
caused by (i) the Bank's willful  misconduct or gross  negligence in determining
whether  documents  presented  under the Letter of Credit  comply with the terms
thereof  or (ii) the  Bank's  willful  failure to pay under the Letter of Credit
after the  presentation to it by the Trustee (or a successor under the Ordinance
to whom the Letter of Credit has been  transferred in accordance with its terms)
of a draft and certificate  strictly  complying with the terms and conditions of
the Letter of Credit. In furtherance and not in limitation of the foregoing, the
Bank may accept  documents  that  appear on their  face to be in order,  without
responsibility   for  further   investigation,   regardless  of  any  notice  or
information to the contrary.

         SECITON 28. Costs, Expenses and Taxes.

         (a) The Company agrees to pay on demand all  out-of-pocket  expenses of
the Bank,  including  reasonable fees and  disbursements  of counsel  (including
allocated costs of in-house counsel and all disbursements of in-house  counsel),
in  connection  with (i) the  preparation  of this  Agreement  and the Letter of
Credit  and  otherwise  in  connection  with the  issuance  of the Bonds and the
preparation,  authorization,  execution  and delivery of the Related  Documents,
(ii) any amendments, modifications, extensions, supplements, consents or waivers
hereto  or  thereto,  and  (iii)  the  administration  or  enforcement  of  this
Agreement, the Bonds and the Related Documents and any other documents which may
be delivered in connection herewith or therewith.

         (b) All payments by the Company of  principal  of, and interest on, the
Advances and all other amounts payable hereunder shall be made free and clear of
and  without  deduction  for any  present  or future  income,  excise,  stamp or
franchise taxes and other taxes, fees, duties,  withholdings or other charges of
any nature  whatsoever  imposed  by any  United  States  taxing  authority,  but
excluding  franchise taxes, agency profit taxes and taxes imposed on or measured
by the Bank's net income or receipts (for which  excluded  items the Company has
no liability) (such non-excluded items being called "Taxes").  In the event that
any  withholding  or  deduction  from  any  payment  to be made  by the  Company
hereunder is required in respect of any Taxes  pursuant to any  applicable  law,
rule or regulation, then the Company will

                                      -36-
<PAGE>

                  (i) pay  directly to the  relevant  authority  the full amount
         required to be so withheld or deducted;

                  (ii) promptly forward to the Bank an official receipt or other
         documentation  satisfactory to the Bank evidencing such payment to such
         authority; and

                  (iii) pay to the Bank such additional  amount or amounts as is
         necessary to ensure that the net amount  actually  received by the Bank
         will equal the full  amount such Bank would have  received  had no such
         withholding or deduction been required.

Moreover,  if any Taxes are directly  asserted  against the Bank with respect to
any payment received by the Bank hereunder,  the Bank may pay such Taxes and the
Company will promptly pay such  additional  amounts  (including  any  penalties,
interest or expenses  other than  penalties,  interest or expenses to the extent
they arise from acts or omissions of the Bank) as is necessary in order that the
net amount  received by such person  after the payment of such Taxes  (including
any taxes on such  additional  amount)  shall equal the amount such person would
have received had no such Taxes been asserted.

         (c) If the Company  fails to pay any Taxes when due to the  appropriate
taxing  authority or fails to remit to the Bank the  required  receipts or other
required  documentary  evidence,  the Company  shall  indemnify the Bank for any
incremental Taxes,  interest or penalties that may become payable by the Bank as
a result of any such failure.

         SECTION 29.  Severability.  Any  provision of this  Agreement  which is
prohibited,  unenforceable  or not authorized in any  jurisdiction  shall, as to
such   jurisdiction,   be  ineffective  to  the  extent  of  such   prohibition,
unenforceability  or   non-authorization   without  invalidating  the  remaining
provisions hereof or affecting the validity,  enforceability or legality of such
provision in any other jurisdiction.

         SECTION 30. Assignments and Participations.d Participations

         (a) This Agreement shall be binding upon the Company and its successors
and assigns and inure to the benefit of and be  enforceable  by the Bank and its
successors, transferees and assigns; provided, however, that the Company may not
assign all or any part of its rights or obligations under this Agreement without
the prior written consent of the Bank.

                                      -37-
<PAGE>



         (b) The Bank may with the prior written  consent of the Company  (which
consent  may not be  unreasonably  withheld)  assign  to one or  more  financial
institutions all, or a proportional part of all (in a minimum amount of not less
than $5,000,000),  of its rights and obligations under this Agreement,  and such
assignee shall assume such rights and obligations.  Upon any such assignment the
assignee shall become a party to this Agreement, shall be a "Bank" hereunder and
shall be  entitled  to all of the  rights  and  benefits  hereunder  (including,
without limitation, the rights set forth in Sections 10, 22, 23 and 28).

         (c) The  Bank  may at any  time  sell or  grant  participations  to any
Participant  in all or any part of, or any interest  (undivided  or divided) in,
the  Bank's  rights  and  benefits  under  this  Agreement,  in which  event the
Participant  shall  not have any  rights  hereunder  (the  Participant's  rights
against  the Bank to be as set forth in the  agreement  executed  by the Bank in
favor of the  Participant),  and all amounts  payable by the  Company  hereunder
shall be determined as if the Bank had not sold or granted any participation.

         SECTION 31.  Governing  Law. THIS  AGREEMENT  SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE  WITH, THE INTERNAL LAWS OF THE STATE OF
NEW YORK.

         SECTION  32.  Waiver of Jury  Trial.  THE  COMPANY  AND THE BANK HEREBY
KNOWINGLY,  VOLUNTARILY  AND  INTENTIONALLY  WAIVE ANY RIGHTS THEY MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY  LITIGATION  BASED  HEREON,  OR ARISING  OUT OF,
UNDER OR IN CONNECTION  WITH,  THIS  AGREEMENT OR ANY RELATED  DOCUMENT,  OR ANY
COURSE OF CONDUCT,  COURSE OF DEALING,  STATEMENTS  (WHETHER ORAL OR WRITTEN) OR
ACTIONS OF THE COMPANY OR THE BANK. THE COMPANY  ACKNOWLEDGES AND AGREES THAT IT
HAS RECEIVED FULL AND SUFFICIENT  CONSIDERATION FOR THIS PROVISION AND THAT THIS
PROVISION IS A MATERIAL  INDUCEMENT FOR THE BANK'S  ENTERING INTO THIS AGREEMENT
AND EACH SUCH RELATED DOCUMENT TO WHICH IT IS A PARTY.

         SECTION 33.  Headings and Table of Contents.  Section  headings and the
Table of Contents in this  Agreement  are  included  herein for  convenience  of
reference  only and shall not  constitute a part of this Agreement for any other
purpose.

         SECTION 34. Counterparts.  This Agreement may be executed in any number
of counterparts,  each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

         defined in Section 8-102 of the U.C.C.) to effect the "delivery" of the
         Pledged  Bonds to the  Collateral  Agent and the pledge of the  Pledged
         Bonds to the Collateral Agent, for the benefit of the Bank, as provided
         in,  and in  accordance  with,  Section  8-320 of the  U.C.C.,  or (ii)
         evidence that a financial intermediary has identified the Pledged Bonds
         as having been  pledged to the  Collateral  Agent and has  supplied the
         Collateral Agent with confirmation thereof (including,  if requested by
         the Collateral  Agent, the delivery to the Collateral Agent of a notice
         from the Company to the  financial  intermediary  substantially  in the
         form  of  Attachment  I  hereto,  duly  acknowledged  by the  financial
         intermediary),  all as provided  in, and in  accordance  with,  Section
         8-313(1)(d)(i) of the U.C.C.  (including the requirement of specificity
         required  therein),  which  evidence  shall have been  delivered to the
         Collateral  Agent,  all  in  form  and  substance  satisfactory  to the
         Collateral Agent and the Bank;  provided,  however,  that in any event,
         all other  necessary and  appropriate  action and approvals  shall have
         been  taken  or  received  to  grant  to the  Collateral  Agent a first
         priority fully perfected security interest in the Pledged Bonds.

         SECTION 2.7. No Disposition.  The Company agrees that it will not sell,
assign,  transfer,  exchange or  otherwise  dispose of, or grant any option with
respect  to, the  Collateral,  nor will it create,  incur or permit to exist any
liens, security interests, options or other charges or encumbrances with respect
to all or any part of the Collateral,  except for the security  interest of this
Pledge Agreement.


                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

         SECTION 3.1. Warranties,  etc. The Company represents and warrants unto
the Bank, as at the date of each pledge and delivery hereunder by the Company to
the Collateral Agent of any Collateral, as set forth in this Article.

         SECTION 3.1.1.  Ownership, No Liens, etc. The Company is or will be the
legal and  beneficial  owner of, and has good and  marketable  title to (and has
full right and authority to pledge and assign) such  Collateral,  free and clear
of all liens,  security  interests,  options,  or other charges or encumbrances,
except any lien or security  interest  granted  pursuant  hereto in favor of the
Collateral Agent.

         SECTION 3.1.2. Valid Security  Interest.  The execution and delivery of
this Pledge  Agreement,  together  with the delivery of such  Collateral  to the
Collateral  Agent (or, to the extent any Collateral is in book-entry  form, upon
the making of  appropriate  entries  in the  relevant  books and  records of any
clearing  corporation  or  financial  intermediary,  as the case  may be,  which
entries in the case of all relevant  Collateral,  will be made promptly upon any
such property becoming Collateral  hereunder),  are effective to create a valid,
perfected, first priority security interest in favor of the Collateral Agent for
the benefit of the Bank, in such Collateral and all proceeds  thereof,  securing
the Secured Obligations.  No filing or other action will be necessary to perfect
or protect such security interest.


                                   ARTICLE IV
                              THE COLLATERAL AGENT

         SECTION 4.1. Collateral Agent Appointed  Attorney-in-Fact.  The Company
hereby irrevocably appoints the Collateral Agent the Company's attorney-in-fact,
with full power of substitution and full authority in the place and stead of the
Company  and in the name of the Company or  otherwise,  from time to time in the
Bank's  discretion,  to take any action and to execute any instrument  which the
Collateral  Agent may deem  necessary or advisable to accomplish the purposes of
this Pledge Agreement, including without limitation:

                  (a)  after  the  occurrence  and  continuance  of an  Event of
         Default, to ask, demand, collect, sue for, recover, compromise, receive
         and give  acquittance  and  receipts  for  moneys due and to become due
         under or in respect of any of the Collateral;

                  (b) to receive, endorse and collect any drafts or other
         instruments, documents and chattel paper, in connection with clause
         (a) above; and

                  (c) to file any  claims or take any  action or  institute  any
         proceedings  which the Collateral Agent may deem necessary or desirable
         for the collection of any of the Collateral or otherwise to enforce the
         rights of the Collateral Agent with respect to any of the Collateral.

The Company hereby acknowledges,  consents and agrees that the power of attorney
granted pursuant to this Section is irrevocable and coupled with an interest.

         SECTION 4.2. Collateral Agent May Perform.  Either the Collateral Agent
or the Bank may from  time to time,  at its  option,  perform  any act which the
Company agrees  hereunder to perform and which the Company shall fail to perform
after being requested in writing so to perform (it being understood that no such
request  need be given after the  occurrence  and during the  continuance  of an
Event of  Default)  and the  Collateral  Agent or the Bank may from time to time
take any other action which the Collateral  Agent or the Bank  reasonably  deems
necessary  for  the  maintenance,  preservation  or  protection  of  any  of the

         SECTION 4.3. Collateral Agent Has No Duty. The powers and discretionary
rights  conferred on the  Collateral  Agent  hereunder are solely to protect its
interest (on behalf of the Bank) in the Collateral and shall not impose any duty
on it to exercise any such powers.  Except for reasonable care of any Collateral
in its actual  possession and the accounting for moneys actually  received by it
hereunder,  the  Collateral  Agent  shall have no duty as to any  Collateral  or
responsibility for

                  (a)  ascertaining  or taking  action  with  respect  to calls,
         conversions,  exchanges,  maturities, tenders or other matters relative
         to any Pledged Property,  whether or not the Collateral Agent has or is
         deemed to have knowledge of such matters, or

                  (b) taking any necessary steps to preserve rights against
         prior parties or any other rights pertaining to any Collateral.

         SECTION 4.4.  Reasonable  Care. The Collateral Agent shall be deemed to
have exercised reasonable care in the custody and preservation of the Collateral
in its possession if the Collateral is accorded treatment substantially equal to
that  which  the  Collateral  Agent  accords  its  own  property  consisting  of
negotiable instruments.


                                    ARTICLE V
                                    REMEDIES

         SECTION 5.1.  Certain Remedies.  If any Event of Default shall have
occurred and be continuing:

                  (a) The Bank may  exercise  in respect of the  Collateral,  in
         addition to other rights and remedies  provided for herein or otherwise
         available  to it,  all the rights and  remedies  of a secured  party on
         default  under the U.C.C.  (whether  or not the  U.C.C.  applies to the
         affected  Collateral) and also may,  without notice except as specified
         below,  sell the  Collateral or any part thereof in one or more parcels
         at public or private sale,  at any of the Bank's  offices or elsewhere,
         for cash, on credit or for future  delivery,  and upon such other terms
         as the Bank may deem commercially reasonable.  The Company agrees that,
         to the extent  notice of sale shall be  required  by law,  at least ten
         days'  prior  notice to the Company of the time and place of any public
         sale or the time  after  which  any  private  sale is to be made  shall
         constitute reasonable notification.  The Bank shall not be obligated to
         make any sale of  Collateral  regardless  of notice of sale having been
         given.  The Bank may  adjourn  any public or private  sale from time to
         time by  announcement  at the time and place fixed  therefor,  and such
         sale  may,  without  further  notice,  be made at the time and place to
         which it was so adjourned.

                  (b)      The Bank may

                           (i) transfer all or any part of the  Collateral  into
                  the  name  of  the  Bank  or  its  nominee,  with  or  without
                  disclosing  that such  Collateral  is  subject to the lien and
                  security interest hereunder,

                           (ii) notify the parties obligated on any of the
                  Collateral to make payment to the Bank of any amount due or to
                  become due thereunder,

                           (iii) enforce  collection of any of the Collateral by
                  suit or otherwise,  and surrender,  release or exchange all or
                  any part  thereof,  or  compromise  or extend or renew for any
                  period  (whether or not longer than the  original  period) any
                  obligations of any nature of any party with respect thereto,

                           (iv) endorse any checks, drafts, or other writings in
                  the Company's name to allow collection of Collateral,

                           (v)  take control of any proceeds of the Collateral,
                  and

                           (vi)  execute  (in the  name,  place and stead of the
                  Company)  endorsements,  assignments,  stock  powers and other
                  instruments  of  conveyance or transfer with respect to all or
                  any of the Collateral.

         SECTION 5.2.  Compliance with Restrictions.  The Company agrees that in
any  sale of any of the  Collateral  whenever  an Event of  Default  shall  have
occurred and be  continuing,  the Bank is hereby  authorized  to comply with any
limitation or restriction  in connection  with such sale as it may be advised by
counsel is necessary in order to avoid any violation of applicable law including
compliance  with such  procedures  as may  restrict  the  number of  prospective
bidders and  purchasers,  require that such  prospective  bidders and purchasers
have  certain   qualifications,   and  restrict  such  prospective  bidders  and
purchasers to persons who will  represent and agree that they are purchasing for
their own  account for  investment  and not with a view to the  distribution  or
resale of such  Collateral,  or in order to obtain any required  approval of the
sale or of the purchaser by any governmental  regulatory  authority or official,
and the Company  further  agrees that such  compliance  shall not result in such
sale  being  considered  or  deemed  not to have  been  made  in a  commercially
reasonable  manner,  nor shall the Bank be liable or  accountable to the Company
for any discount  allowed by the reason of the fact that such Collateral is sold
in compliance with any such limitation or restriction.

         SECTION 5.3. Application of Proceeds. All cash proceeds received by the
Bank in respect of any sale of,  collection from, or other realization upon, all
or any part of the Collateral may, in the discretion of the Bank, be held by the
Bank as additional collateral security for, or then or at any time thereafter be
applied in whole or in part by the Bank against,  all or any part of the Secured
Obligations  in such order as the Bank shall elect.  Any surplus of such cash or
cash proceeds  held by the Bank and  remaining  after payment in full of all the
Secured  Obligations  shall be paid over to the Company or to whomsoever  may be
lawfully entitled to receive such surplus.

         SECTION 5.4.  Sale of Collateral.

         (a) The  Company  recognizes  that the Bank may  resort  to one or more
private sales of the Collateral  which may result in prices and other terms less
favorable   to  the  seller   than  if  such  sale  were  a  public   sale  and,
notwithstanding  such circumstances,  agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner.

         (b) The Company further agrees to do or cause to be done all such other
acts and  things  as may be  necessary  to make such sale or sales of all or any
part of the Pledged Bonds valid and binding and in  compliance  with any and all
applicable laws,  rules,  regulations,  orders or decrees,  all at the Company's
expense.  The  Company  further  agrees  that a breach  of any of the  covenants
contained in this Section  will cause  irreparable  injury to the Bank for which
the Bank would have no adequate  remedy at law in respect of such breach and, as
a  consequence,  agrees that each and every  covenant  contained in this Section
shall be specifically  enforceable  against the Company,  and the Company waives
and agrees not to assert any defenses against an action for specific performance
of such  covenants  except for a defense  that no Event of Default has  occurred
under the Reimbursement Agreement.

         SECTION 5.5.  Indemnity and Expenses.  Neither the Collateral Agent nor
the Bank nor any of their respective  officers,  directors,  employees,  agents,
attorneys-in-fact or affiliates shall be liable for any action lawfully taken or
omitted to be taken by it or such person under or in connection with this Pledge
Agreement  (except  for its or such  person's  own gross  negligence  or willful
misconduct).  The Company hereby  indemnifies  and holds harmless the Collateral
Agent and the Bank from and against any and all claims,  losses and  liabilities
arising out of or resulting from this Pledge Agreement (including enforcement of
this Pledge Agreement),  except claims, losses or liabilities resulting from the
Collateral  Agent's or the Bank's gross  negligence or wilful  misconduct.  Upon
demand, the Company will pay to the Bank or to the Collateral Agent, as the case
may be, the amount of any and all reasonable expenses,  including the reasonable
fees and  disbursements of its counsel and of any experts and agents,  which the
Bank or the Collateral Agent, as the case may be, may incur in connection with:

                  (a)  the   administration  of  this  Pledge   Agreement,   the
         Reimbursement Agreement and each other Related Document;

                  (b) the custody,  preservation,  use, or operation  of, or the
         sale  of,  collection  from,  or  other  realization  upon,  any of the
         Collateral;

                  (c) the  exercise or  enforcement  of any of the rights of the
         Bank or the Collateral Agent hereunder; or

                  (d) the  failure by the  Company to perform or observe  any of
         the provisions hereof.

The  Collateral  Agent may rely and shall be protected  in acting or  refraining
from  acting  upon any  written  notice,  certificate,  instruction  or  request
furnished  to it  hereunder  and  believed  by it to be genuine and to have been
signed or presented by the proper party.  The Collateral  Agent may consult with
counsel of its own choice and shall  have full and  complete  authorization  and
protection for any action taken or suffered by it hereunder in good faith and in
accordance with the opinion of such counsel.

        Note,  the Owner  Participant  may in its sole  discretion  increase  or
        decrease the average life of each tranche of the Fixed Rate Notes by six
        months with a view to  providing an optimal  debt  structure  consistent

        operation of Section 3(d) of the Facility Lease, the Owner Trustee shall
        deliver to the Indenture Trustee a certificate  pursuant to such Section
        3.12. Notwithstanding the foregoing, the Indenture Trustee and the Owner
        Trustee may rely on such  certificate  and shall have no  obligation  to

                (13)  Litigation.  There is no action,  suit,  investigation  or
        proceeding  pending  or,  to the  knowledge  of the  Lessee,  threatened
        against  PNM  before  any  court,   arbitrator  or   administrative   or
        governmental body which questions the validity or enforceability of this
        Participation  Agreement or any other Transaction  Document to which the
        Lessee is, or is to become,  a party,  or  (except as  described  in the
        reports to which  reference  is made in the last  sentence of  paragraph
        (12)  above)  which,  individually  or  in  the  aggregate,  if  decided
        adversely to the interests of the Lessee,  would have a material adverse
        effect on the business or financial  condition of PNM or materially  and
        adversely  affect the ability of the Lessee to perform  its  obligations
        under this Participation  Agreement or any other Transaction Document to
        which it is, or is to become, a party.

                (14) Tax Returns. The Lessee has filed all Federal, state, local
        and foreign,  if any, tax returns which were  required to be filed,  and
        has paid all Taxes shown to be due and  payable on such  returns and has
        paid all other Taxes in respect of the  Lessee's  interest in Unit 2 and
        in the PVNGS Site  which are  payable by PNM to the extent the same have
        become due and payable and before  they have become  delinquent,  except
        for (i) any Taxes the amount,  applicability or validity of which may be
        in dispute  and which are  currently  being  contested  in good faith by
        appropriate  proceedings  and with respect to which PNM has set aside on
        its books  reserves  (segregated  to the extent  required  by  generally
        accepted accounting principles) deemed by it to be adequate and (ii) any
        Taxes relating to PVNGS in respect of which the Operating  Agent has not
        given  notice  to PNM that the same  are due and  payable.  The  Federal
        income tax returns of PNM have been audited by the IRS for taxable years
        through 1980.

        Owner Participant in Section 7(a)(9),  the execution and delivery by the
        Lessee  of  this  Participation  Agreement  and  the  other  Transaction
        Documents  and  Financing  Documents  to which the  Lessee  is, or is to
        become on or before  the  Closing  Date,  a party will not  involve  any
        prohibited  transaction  within the meaning of ERISA or Section  4975 of
        the Code.

                (16)  Regulation.  So long as the  Facility  Lease is in effect,
        assuming  the  proper  filing  of Form U-7D with the SEC on or within 30
        days after the Closing Date, under Applicable Law now in effect, neither
        the Loan Participant,  the Owner Participant,  FNB nor the Owner Trustee
        will be or  become,  solely by reason of either its  entering  into this
        Participation  Agreement or any other Transaction  Document to which any
        of them is, or is to become, a party, or the  transactions  contemplated
        hereby or thereby,  subject to regulation (i) as an "electric  utility",
        an "electric  utility company",  a "public  utility",  a "public utility
        company", a "holding company",  or a "public utility holding company" by
        any Federal, state (other than, as to the Owner Participant, the laws of
        the states of its principal place of business and of its  incorporation,
        as to which no  representation  or  warranty  is given) or local  public
        utility  commission  or  other  regulatory  body,   authority  or  group
        (including,  without  limitation,  the SEC,  the FERC,  the NMPSC or the
        Arizona  Corporation  Commission)  or (ii) in any manner by the NRC. The
        Lessee  is  not,  and  covenants  that  (except  in  connection  with  a
        transaction  permitted  by  Section  10(b) (3) (ii)  hereof) it will not
        become,  a "holding  company"  or a  "subsidiary  company" of a "holding
        company" or an "affiliate" of a "holding  company" within the meaning of
        the Holding  Company Act. The Lessee is not subject to regulation by the
        Arizona  Corporation  Commission as a public utility or a public service
        corporation.

                (17)  Authorizations,  etc.  PNM has not  failed to  obtain  any
        Governmental Action or other authorization,  license,  approval, permit,
        consent,  right or  interest,  where a  failure  to  obtain  such  would
        materially  and  adversely  affect  the  ability  of PNM to carry on its
        business as presently conducted.

                (18) No Default,  etc.  PNM 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 PNM,  under the  Existing  Mortgage or any other
        material mortgage,  deed of trust,  indenture,  lease, contract or other
        instrument or agreement to which PNM 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  (other than
        those referred to in clauses (x) through (xiv) of the definition of such
        term,  true and  correct  copies  of which  will be  delivered  promptly
        following  the  closing  Date)  and  the  Existing  Mortgage  have  been
        delivered to Milbank,  Tweed, Hadley & McCloy. No ANPP Project Agreement
        will, on and after the Closing Date,  materially and adversely interfere
        with (i) (except for the ANPP  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 ANPP  Participation  Agreement and each other ANPP Project Agreement
        is 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 2 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  under, and 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 the 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
        the Owner  Trustee  nor the Owner  Participant  shall,  by virtue of the
        transactions   contemplated   by  the   Transaction   Documents,   be  a
        "Transferee" under Section 15.10 of the ANPP Participation Agreement.

                (20) Unit 2. The description of Unit 2 set forth in Exhibit B to
        the Bill of Sale, as delivered on the closing Date,  will be correct and
        sufficiently complete to identify such property.

                (21) Investment Company Act. PNM is not an "investment company",
        or a company "controlled" by an "investment company", within the meaning
        of the Investment company Act.

                (b)     Agreements.

                (1)  Delivery  of  Documents.  The  Lessee  agrees  that it will
        deliver to the Owner  Participant and the Loan Participant  (and, in the
        case of Sections 10(b) (1) (iii) and (v), the Owner Trustee):

                      (i) Financial Statements: (A) as soon as practicable,  and

                   (viii) ANPP Project  Agreements.  Except where the failure to
                do so would  not  have a  material  and  adverse  effect  on the
                Undivided  Interest,  the Real Property Interest,  Unit 2 or the
                rights, interests and benefits of the Owner Trustee or the Owner

                impairment thereof, (4) enforce the ANPP Participation Agreement
                in accordance  with its terms and (5) not take,  fail to take or
                join in (i) any action  with  respect  to, nor accept or approve
                any  amendment  or any other  change in, the ANPP  Participation
                Agreement or any other ANPP Project Agreement or (ii) any action
                or change the effect of which  would be to relieve the Lessee of
                any  obligation  under the ANPP  Participation  Agreement  on or
                after the Closing  Date.  The Lessee will not,  unless the Owner
                Participant otherwise consents,  accept or approve any amendment

                Participant  in its  capacity as lessor in a sale and  leaseback
                transaction  or (y)  any  present  or  future  ANPP  Participant
                because such ANPP Participant  derived or will derive its status
                as "Participant"  under the ANPP Participation  Agreement from a
                lessor in a sale and leaseback  transaction,  or (D) deprive the
                owner Trustee or the Owner  Participant,  as the case may be, of
                the  benefit  of  Sections  15.2.2,  15.10  and 32.1 of the ANPP
                Participation    Agreement   (or   any   comparable    successor
                provisions). The Lessee shall (X) provide copies of any proposed
                amendment to or modification of the ANPP Participation Agreement
                to the  Owner  Participant  not less  than 45 days  prior to the
                execution  thereof  by the  Lessee  (except  where the Lessee is
                unaware thereof 45 days prior to such  execution,  in which case
                the Lessee shall provide  notice thereof as promptly as possible
                after becoming so aware) and (Y) upon such execution  furnish to
                the  Owner   Participant  a  copy  of  any  such   amendment  or
                modification  as  executed.  The  Lessee  will  not,  except  as
                permitted by paragraph  (ii) above,  sell,  transfer,  assign or
                otherwise dispose of, except in the ordinary course of operation
                of PVNGS, all or any of its rights or interests in and to PVNGS.

                date  of  the  mandatory  sinking  fund  redemption   applicable
                thereto,  (2)  the  aggregate  of  Bonds  of any one  series  so
                purchased  shall not exceed the amount of the,  next  succeeding
                sinking  fund  payment  applicable  thereto and (3) any Bonds so
                purchased  shall  be the  subject  of a  request  by the  Lessee
                pursuant  to  the   provisions  of  the   commitment   agreement
                applicable to such series of Bonds.

                      (x) Cooperation.  The Lessee will cooperate with the Owner
                Participant  and the Owner  Trustee in  obtaining  the valid and

                of all Governmental Actions (including,  but without limitation,
                the  License)   necessary  or,  in  the  opinion  of  the  Owner
                Participant,   desirable  for  the   ownership,   operation  and
                possession  of the  Undivided  Interest  (including  the related
                Generation Entitlement Share), the Real Property Interest or any
                portion of Unit 2  represented  thereby by the Owner  Trustee or
                any transferee,  lessee or assignee  thereof for the period from

                obligations under Applicable Law concerning the  Decommissioning
                of Unit 2. If Applicable Law or  Governmental  Action shall not,
                on or before  December  31,  1990,  impose  upon the  Lessee the
                obligation  to create and  maintain  an  external  reserve  fund
                (which may be a fund which  qualifies  under Section 468A of the
                Code) dedicated to paying all Decommissioning  Costs relating to
                the Undivided Interest, then the Lessee will create and maintain
                such  a fund  on  terms  reasonably  satisfactory  to the  Owner

                or proceeds are attributable to the  decommissioning  obligation
                of the Lessee under this Section  10(b) (3) (xi) with respect to

                from and  after  the date of such  sale  through  the  remaining
                useful life of Unit 2 (whereupon the  reimbursement  obligations
                of  the  Lessor  under  this   Section   10(b)  (3)  (xi)  shall
                terminate); provided, however, that any such reimbursement shall
                not reduce the amount of such net sales proceeds retained by the

                20% of  Facility  Cost  (reduced by the  percentage  of Facility
                Cost, if any, actually realized by the Lessor pursuant to clause
                (C) above).  The  reimbursement  obligations of the Lessor under
                clauses  (C) and (D)  above  are for  the  sole  benefit  of the
                Lessee,  and no other Person shall be a third party  beneficiary
                with  respect  thereto.  In the event  that the  Lessee  and the
                Lessor  shall not agree as to the  amount  of gross  rents,  net
                electric  revenues  or net sales  proceeds  attributable  to the
                decommissioning  obligation  of the Lessee  under  this  Section
                l0(b)(3)(xi),  such amount shall be  determined by the Appraisal
                Procedure.  For  purposes  of  determining  Facility  Cost under
                clauses (C) and (0) of this Section l0(b)(3)(xi),  Facility Cost
                shall be adjusted to reflect  inflation  or  deflation  from the
                Closing Date to the time of determination.

                    (xii) Other Leases with Respect to PVNGS.  The Lessee agrees
                that  it  will  deliver  to  the  Owner  Participant,   promptly
                following  execution and delivery  thereof by the,  Lessee,  all
                transaction  documents  pertaining  to any  sale  and  leaseback
                transaction  that the Lessee or any  Affiliate of the Lessee may
                enter into with respect to PVNGS.  The Lessee  agrees,  upon the
                written  request of the Owner  Participant  delivered  within 60
                days of receipt of  transaction  documents  with respect to each
                such  transaction,   to  enter  (within  a  reasonable  time  as
                specified  in such  request)  into an  amendment to the Facility
                Lease as necessary to incorporate  therein (in  substitution for
                the definitions of such terms theretofore  appended thereto) and
                at the option of the Owner  Participant,  any one or more of the
                following  three  alternatives:  (I) the  definitions of "Deemed

                Act or any other  Applicable  Law  relating  to the  matters set
                forth in clause (2) of the  definition  of "Deemed  Loss  Event"
                contained  in Appendix A hereto,  in each case as appended to or
                contained in the Facility Lease entered into in connection  with

                foregoing,  the  definitions  of any of such terms shall include
                such other terms as may be used in such  transaction  to connote
                events  similar  to those  contained  in any of the  definitions
                referred to above. In connection  with any such  amendment,  the
                Owner  Participant  shall  submit  (subject  to  review  by  the
                Lessee's  financial  advisors) new Schedules of Special Casualty
                Values and/or  casualty  Values,  in each case calculated on the
                same  assumption  as the  comparable  schedules  appended to the
                Subject  Lease.  In  connection  with any such  amendment,  such
                substituted definitions shall include and be subject to, mutatis
                mutandis,  the same  qualifications and waivers and incorporate,
                mutatis  mutandis,  the same definitions as shall be provided in
                the Subject Lease or related transaction  documents with respect
                to any of the  definitions  referred  to  above  which  shall be
                substituted.

                   (xiii)  Acknowledgment  and  Agreement.   The  Lessee  hereby
                acknowledges and agrees to the provisions of Section 7(b) (4) of

                request  of the  Owner  Participant  and at the  expense  of the
                Lessee,  the Lessee (if permitted by Applicable Law and the ANPP
                Participation  Agreement)  will  enter  into  amendments  to the
                Transaction   Documents  as  necessary  to  reflect   reasonable
                alternative  arrangements  with  respect  to the  Real  Property
                Interest  involving  the  transfer  of the Real  Property to the
                Lessee,  the  grant to the  Lessor  of  easements,  an option to
                purchase  a  ground  lease  or other  rights  (or a  combination
                thereof) with respect to the Real Property

                 unless the Lessee shall have determined,  based upon an opinion
                 of  counsel,   that  such   arrangements  will  not  materially
                 adversely  affect the status of the Owner  Participant as owner
                 of the Undivided Interest for Federal income tax purposes.

                      (xv) Amendment of Subject and Subordinate Provisions.  The
                Lessee  shall  not  unreasonably  withhold  its  consent  to any
                proposed  amendment to the ANPP  Participation  Agreement  which
                would  have the effect of  eliminating  the  provisions  thereof
                under  which  the  rights  of the  Owner  Trustee  and the Owner
                Participant  hereunder  shall be subject and  subordinate to the
                rights of the ANPP Participants,  provided that the Lessee shall
                have no obligations to initiate any such amendment.

        a  result  of,  such   withholding  tax.  Whether  or  not  any  of  the
        transactions contemplated hereby are consummated,  except as provided in

        hold each Indemnitee harmless,  on an After-Tax Basis, from and against,
        any and all Taxes howsoever  imposed (whether imposed on or with respect
        to the Indemnitee,  the Lessee, Unit 2, the Undivided Interest, the Real
        Property Interest, any Capital Improvement or the PVNGS Site or any part

                limitation,  any minimum Taxes, capital gains Taxes, withholding
                Taxes,  any Taxes on, or measured by,  items of tax  preference1

                such  Taxes,  except,  with  respect to the Owner  Trustee,  the
                Trust, the Trust Estate, the Owner Participant and any Affiliate
                of any thereof,  any such Taxes imposed by a  jurisdiction  as a
                result of a relation or asserted  relation of such  jurisdiction
                to the transactions contemplated by the Transaction Documents or
                the Financing  Documents or as a result of the activities of the
                Lessee,  any ANPP Participant or any Affiliate of any thereof in
                such  jurisdiction;  provided,  however,  that the amount of any
                such excepted Taxes shall be calculated (i) on a pro forma basis
                assuming that such  Indemnitee  has no other  taxable  income or
                loss in the taxing jurisdiction  imposing the Tax (provided that
                such  calculation  shall take into  account  any  allocation  or
                apportionment  method  used by such  jurisdiction  except to the
                extent  that  such  method  takes  into  account  the  income or
                activities  of business  entities  organized  outside the United
                States)  and is able to use any net  operating  loss  carryovers
                based  on such  pro  forma  calculation  to the  fullest  extent
                allowed  by law and  (ii) by  taking  into  account  any  actual
                reduction  in  Taxes in any  other  jurisdiction  in which  such
                Indemnitee  is subject to tax (whether  such  reduction  results
                from the operation of allocation or apportionment formulas, from
                credits  or  otherwise)   which   reduction   results  from  the
                transactions  contemplated by the  Transaction  Documents or the
                Financing  Documents;  provided  further,  however,  that,  with
                respect  to any Tax based on, or  measured  by,  capital  or net
                worth,  the Lessee's  indemnity  obligation shall not exceed the
                incremental portion of such Tax attributable to the transactions
                contemplated by the Transaction Documents;

                been  delivered to the Lessor as provided in Section 5(a) of the
                Facility Lease, but excluding the Agency Period,  if any, unless
                such Taxes relate to events  occurring or matters  arising prior
                to or simultaneously with such date;

                in the Undivided Interest, the Real Property Interest, the Trust
                Estate,  the Indenture  Estate,  the Notes or any other right or
                interest   arising  under  the  Transaction   Documents  or  the
                Financing Documents, unless an Event of Default has occurred and
                is continuing,  or Taxes arising from an involuntary transfer by
                such  Indemnitee of any such interest  arising from a bankruptcy
                or similar  proceeding  in which such  Indemnitee  is the debtor

                Default  or Event of  Default  by the  Lessee  or an  Affiliate.
                thereof;

                      (v) Taxes based on or measured by any fees,  commission or
                compensation received by an Indemnitee for acting as trustee, or
                for  other  services  rendered,  in  connection  with any of the

                      (vi) Taxes on or with respect to an Indemnitee  arising by
                reason of such  Indemnitee's  failure to file  proper and timely
                reports or returns (unless the filing of such reports or returns

                tax  imposed  by reason of such  Indemnitee's  failure to comply

                comply with its obligations under Section 13(b)(6),  unless such
                failure  results from any action of the Lessee or failure by the
                Lessee to comply with any provision of the Transaction Documents
                or the  Financing  Documents,  including  the failure to provide
                necessary information;

                      (vii) Taxes on or with respect to an Indemnitee arising as
                a result of a material failure of such Indemnitee to fulfill its
                obligations  with  respect  to  the  contest  of  any  claim  in
                accordance   with   Section   l3(b)(4)  of  this   Participation
                Agreement;

                      (viii)  Taxes  imposed on or with  respect to a transferee
                (or subsequent transferee) of an original Indemnitee (other than
                a  transferee  or  subsequent  transferee  either of which is an
                Affiliate  of the  original  Indemnitee)  to the extent that the
                amount of such Taxes exceeds the amount of taxes that would have
                been imposed on or with respect to such original  Indemnitee but
                for the transfer to such  transferee  or, if imposed,  would not
                have been subject to  indemnification  under this Section 13(b);
                provided,  however,  that the exception in this clause shall not
                apply to any transferee  where such transfer shall have occurred
                during the continuance of an Event of Default:

                      (ix)  any  Taxes  imposed  on  the  Lessor  or  the  Owner
                Participant resulting from, or which would not have occurred but
                for, Lessor's Liens or Owner  Participant's  Liens and any Taxes
                imposed on the  Indenture  Trustee which would not have occurred
                but for Indenture Trustee's Liens;

                      (x) any Tax that results  solely from the activities of an
                Indemnitee  in any  taxing  jurisdiction  which  activities  are
                unrelated to the  transactions  contemplated  by the Transaction
                Documents or the Financing Documents:

                      (xi) any Tax on or with respect to an Indemnitee resulting
                from  any  amendment  or  modification   entered  into  by  such
                Indemnitee to any Transaction  Document or Financing Document if
                the Lessee is not a party to such amendment or  modification  or
                has not  consented to such  amendment or  modification,  in each
                case  unless an Event of  Default  shall  have  occurred  and be
                continuing; and

                      (xii)  any  Tax  on  or  with  respect  to  an  Indemnitee
                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 such Tax
                is the responsibility of the Lessee under this Section 13(b)).

provided,  however,  that the  foregoing  subdauses  (i) through (xii) shall not
apply to any Tax imposed on the Loan  Participant or the indenture  estate under
the Collateral Trust Indenture.

                (3)  Calculation  of  General  Tax  Indemnity  Payments.  If any
        Indemnitee realizes a net permanent tax benefit by reason of the payment
        of any indemnity under Section  13(b)(l),  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 (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),  and
        (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
        to this Section 13(b) less the aggregate amount of all prior payments by
        such  Indemnitee to the Lessee  pursuant to this clause (y) with respect
        to amounts paid pursuant to Section 13(b)(l),  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) except as provided in Section 13(b)(2)(vii). If the Lessee
        shall  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 (including the amount) 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 $125,000, (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  penalty  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; (w) the Lessee shall have agreed to pay such Indemnitee on
       demand 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 2, 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)(6)
       hereof) as a result of any payment by such  Indemnitee  made  pursuant to
       this  sentence  (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;

<PAGE>

        provided,  however,  that in computing any 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 (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.

                (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 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  report1  return or
       statement  to  the  Owner  Trustee  and  such   Indemnitee  in  a  manner
       satisfactory to the Owner Trustee and such Indemnitee within a 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  (except with respect to Arizona  real  property  taxes,
        which shall be paid before they become delinquent) 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 the Lessee  under
        this Section 13(b) and it shall be necessary,  in 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  16ca1  taxing
        jurisdiction,  shall mean and include any  consolidated or combine 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.  Each Indemnitee shall provide to the
Lessee such  supporting  material  (other than tax  returns) as the Lessee shall
reasonably  request in connection  with the matters set forth in Section  13(b).
The Lessee shall reimburse to any Indemnitee any expenses  incurred in providing
requested supporting material to the Lessee.

                (d) Cooperation. The Owner Participant shall cooperate and shall
cause the Owner Trustee to cooperate with and consider in good faith any request
by, the  Lessee,  upon the  written  request  and at the  expense  (including  a
reasonable  allowance for internal legal costs) of the Lessee, in order to avoid
or minimize any taxes for which the Lessee is  responsible  under  Section 13(b)
hereof.

Upon  any  transfer  permitted  pursuant  to  the  foregoing   provisions,   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 (including,  without limitation,  the Trust
Agreement) 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
provisions  contained in the first  sentence of this  Section  15(c)) is for the
benefit of the Lessee,  the Owner Trustee and the Owner  Participant and may not
be enforced by any other party hereto. The Owner Participant agrees that it will
use reasonable  efforts to provide (or cause to be provided) such information as
the Lessee  may  reasonably  request to comply  with  requests  for  information
received from the NRC with respect to the  Transferee  (provided  that the Owner
Participant  shall not be  required  to provide  (or cause to be  provided)  any
information of a confidential or proprietary nature).

provisions  or  conditions  of any of the  Transaction  Documents  or  Financing
Documents.  The  obligations  of the Lessee under  Sections 10(b) (2), 10(b) (3)

                  SECTION 19. Miscellaneous.

                (a) Execution.  This Participation  Agreement may be executed in
any number of  counterparts  and by the  different  parties  hereto on  separate

control of nor shall they be deemed to be under the control of any other  Person
having any  interest in Unit 2, 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 (on behalf
of the Owner Participant) and the owner Participant (on its own behalf) have and
at all  times  shall  retain  the right  separately  to take or  dispose  of the
Undivided Interest and the Real Property Interest, subject only to the rights of
the Lessee and the Loan Participant under the Transaction  Documents.  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 and the Real Property
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 New
        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 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 on such Note and (c) such Holder or the Indenture  Trustee  actually
receives any Excess Amount which  reflects any payment by the Owner  Participant
on account  of clause (b) of this  Section1  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 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 and the waiver letter dated as of the Closing  Date),  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 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.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements   and   other   instruments.,    certificates,    orders,   opinions,

necessary  or advisable  for the  purposes of  rendering  the opinions set forth
herein.

                  Based on the foregoing, we are of the opinion that:

                  (1) Funding Corp. is a corporation  duly organized and validly
        existing in good  standing  under the laws of the State of Delaware  and
        has the  corporate  power  and  authority  to carry on its  business  as
        presently conducted, own its properties,  and enter into and perform its
        obligations under the Participation Agreement and each other Transaction

                  (2) The execution,  delivery and  performance by Funding Corp.
        of the Participation  Agreement and each other Transaction  Document and
        each  Financing  Document  to  which  it  is a  party,  have  been  duly
        authorized  by all  necessary  corporate  action on the part of  Funding
        Corp.  and do not require the consent or approval of the  stockholder of
        Funding Corp.  The  Participation  Agreement and each other  Transaction
        Document and each  Financing  Document to which Funding Corp. is a party
        have been duly executed and delivered by Funding Corp. and, assuming due
        authorization,  execution  and  delivery  by each other  party  thereto,
        constitute  legal,   valid  and  binding  agreements  of  Funding  Corp.
        enforceable against it in accordance with their respective terms.

                (3) Neither the  execution,  delivery or  performance by Funding
        Corp. of the Participation  Agreement or any other Transaction  Document
        or any Financing  Document to which it is a party,  nor the consummation
        by  Funding  Corp.  of  the  transactions   contemplated   thereby,  nor
        compliance by Funding Corp. with the provisions  thereof conflicts with,

        or  results  in the  breach of any  provision  of,  the  Certificate  of
        Incorporation  or By-Laws of Funding Corp.  or any Federal,  Delaware or
        New York law or any  indenture,  mortgage or agreement to which  Funding
        Corp. is a party or by which it or its property is bound or requires any

that  enforceability of the  Participation  Agreement and each other Transaction
Document  and each  Financing  Document  to which  Funding  Corp.  is a party in
accordance with their respective terms may be limited by bankruptcy, insolvency,
reorganization,  moratorium  or other  similar  laws  affecting  enforcement  of
creditors' rights generally, as well as the general principles of equity and the
availability of equitable remedies.

Dear Sirs:

                We have acted as special New York  counsel  for Burnham  Leasing
Corporation, a New York corporation (the Owner Participant),  in connection with
the transactions contemplated by the Participation Agreement1 dated as of August
12, 1986, (the Participation Agreement),  among the Owner Participant, The First
National Bank of Boston,  a national  banking  association,  individually  and a
Owner Trustee,  First PV Funding Corporation,  a Delaware corporation,  Chemical
Bank, a New York banking  corporation,  as Indenture  Trustee and Public Service
Company 6f New Mexico,  a New Mexico  corporation.  All  capitalized  terms used
herein and not  otherwise  defined  herein  shall have the meanings set forth in
Appendix A to the  Participation  Agreement.  This  opinion  is being  delivered
pursuant to Section 11(a) (14) of the Participation Agreement.

                  As  such  counsel  we  have  examined   originals  or  copies,
certified  or  otherwise  identified  to our  satisfaction,  of  such  corporate
records,  agreements  and other  instruments,  certificates;  orders,  opinions,
correspondence   with   public   officials,   certificates   of   officers   and
representatives of the Owner Participant, and other documents, as we have deemed
necessary  or advisable  for the  purposes of  rendering  the opinions set forth
herein.

                  Based upon the foregoing, we are of opinion that:




6091.BURNHAM.1106.08:1


<PAGE>


                (1) The Owner Participant is a corporation  validly existing and
        in good standing  under the laws of its state of  incorporation  and has
        the  corporate  power  and  authority  to  enter  into and  perform  its
        obligations under the Participation Agreement and each other Transaction
        Document to which it is a party.

                    (2) The making and  performance by the Owner  Participant of
         the  Participation  Agreement  and each other  Transaction  Document to
         which the Owner Participant is a party have been duly authorized by all
         necessary  corporate action on the part of the Owner Participant and do
         not require the consent or approval of its stockholders (except for any
         such consents or approvals as have been obtained).

                    (3) The  Participation  Agreement and each other Transaction
         Document  to which  the  Owner  Participant  is a party  have been duly
         executed and delivered by the Owner  Participant and constitute  legal,
         valid and  binding  agreements  of the Owner  Participant,  enforceable
         against it in accordance with their respective  terms,  subject,  as to
         enforceability, to applicable bankruptcy,  insolvency,  reorganization,
         moratorium  and other  similar laws  affecting  the  enforceability  of
         creditors'  rights  generally  and  to  general  principles  of  equity
         (regardless  of  whether  an  enforcement  action  is  considered  in a
         proceeding in equity or at law). In addition, we wish to point out that
         provisions in the Participation  Agreement and in the other Transaction
         Documents  to which the Owner  Participant  is a party which permit the
         Owner Participant to make determinations or take actions may be subject
         to a requirement that such  determinations  be made and such actions be
         taken on a reasonable basis and in good faith.

                    (4) Neither the  execution,  delivery or  performance by the
         Owner  Participant  of  the   Participation   Agreement  or  any  other
         Transaction  Document to which it is a party,  nor the  consummation by
         the Owner  Participant of the transactions  contemplated  thereby,  nor
         compliance  by the  Owner  Participant  with  the  provisions  thereof,
         conflicts  with,  or  results  in the  breach of any  provision  of the
         corporate   charter  or  the  by-laws  of  the  Owner   Participant  or
         contravenes any agreement or instrument to which the Owner  Participant

        is a party of which we are aware,  or requires any  Governmental  Action
        with  respect to the Owner  Participant  under  Federal or New York law,
        except such as are contemplated by the Transaction  Documents (including
        the filing of Form U-7D with the SEC within 30 days of the date  hereof)
        or the Financing Documents or such as have been duly obtained,  given or
        accomplished.

                We are  members  of the  Bar of the  State  of New  York  and we
express  no opinion  with  regard to any law other than the laws of the State of
New York and the Federal  laws of the United  States of America.  We do not hold
ourselves out as experts on the laws of the State of Arizona or the State of New
Mexico,  and to the  extent  such laws may be  relevant  to any  opinion  herein
expressed,  we have, with your  permission,  relied upon the opinions dated this
date of Meyer,  Hendricks,  Victor,  Osborn &  Maledon;  Snell & Wilmer;  Rodey,
Dickason,  Sloan,  Akin & Robb,  P.A.;  and  Keleher  &  McLeod,  P.A.,  without

opinion as to matters  governed by the Atomic  Energy Act or the  Nuclear  Waste
Act.

Gentlemen:

                We have acted as special  counsel to The First  National Bank of
Boston, a national banking association (FNB) in connection with the transactions
contemplated by the  Participation  Agreement,  dated as of August 12, 1986 (the
Participation  Agreement),   among  Burnham  Leasing  Corporation,  a  New  York
corporation (the Owner Participant),  First PV Funding  Corporation,  a Delaware
corporation,  FNB, in its individual capacity and as Owner Trustee under a Trust
Agreement  dated as of August  12,  1986,  with the Owner  Participant  (in such
fiduciary  capacity,  the Owner  Trustee),  Chemical  Bank,  a New York  banking
corporation,  as Indenture  Trustee and Public Service Company of New Mexico,  a
New Mexico  corporation.  All  capitalized  terms used herein and not  otherwise
defined  herein  shall  have  the  meanings  set  forth  in  Appendix  A to  the
Participation  Agreement.  This opinion is being  delivered  pursuant to Section
11(a) (16) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of FNB, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth  herein.  With respect to our opinion set forth
in paragraph 6 hereof,  we have assumed that,  for federal  income tax purposes,



6091.BURNHAM.1106.08:l


<PAGE>

the trust  created by the Trust  Agreement  will be  treated as a grantor  trust
subject to section 671 of the Internal Revenue Code of 1954, as amended. We have
also assumed that each of the Transaction Documents is legal, valid, binding and
enforceable  under  the laws of the  State  of New  York,  subject  only to such
limitations as are set forth below.

                  Based on the foregoing, we are of the opinion that:

                (1) FNB is a national  banking  association  duly  organized and
        validly existing in good standing under the laws of the United States of
        America and has all  requisite  corporate  power and  authority to enter
        into and perform its  obligations  under (x) the Trust Agreement and, to
        extent it is a party to the  Participation  Agreement in its  individual
        capacity,  the Participation  Agreement and (y) acting as Owner Trustee,
        the Participation Agreement and each other Transaction Document to which
        FNB is a party as Owner Trustee.

                (2) The  Participation  Agreement  and  each  other  Transaction
        Document  to which  FNB is a party  have  been  duly  authorized  by all
        necessary  corporate  action of FNB (in its  individual  capacity  or as
        Owner  Trustee,  as the case may be) and,  upon  execution  and delivery
        thereof,  the  Participation  Agreement and each such other  Transaction
        Document will be duly  executed and  delivered and will be legal,  valid
        and  binding   agreements  of  FNB  (in  its   respective   capacities),
        enforceable against it (in its respective capacities) in accordance with
        their respective  terms except as enforcement  thereof may be limited by
        applicable bankruptcy, insolvency, reorganization, moratorium or similar
        laws affecting the rights of creditors  generally and general principles
        of equity (regardless of whether such  enforceability is considered in a
        proceeding  in equity or at law) and except that the  enforceability  of
        certain of the remedial  provisions  in the  Indenture may be limited by
        applicable state laws, which laws,  however,  do not in our opinion make
        the remedies  provided in such  documents  inadequate  for the practical
        realization of the benefits provided thereby.

        Agreement  and, to the extent FNB is a party  thereto in its  individual
        capacity,  the Participation  Agreement and (y) the Owner Trustee of the
        Participation  Agreement and each other Transaction Document (other than
        the Trust  Agreement)  to which the Owner  Trustee  is a party,  nor the
        performance by FNB, in its individual  capacity or as Owner Trustee,  as
        the case may be, of its  obligations  under  each,  conflicts  with,  or
        results in the breach of any  provision  of, its  Charter or By-Laws and
        does not  contravene  any Applicable Law of the United States of America
        or The  Commonwealth  of  Massachusetts  governing  the banking or trust
        powers of FNB, and does not contravene any provision of, or constitute a
        default under, any indenture,  mortgage,  contract or other  instrument,
        known to us, to which FNB is a party or by which it is bound or  require

        Indenture  Default or  Indenture  Event of Default has  occurred  and is
        continuing and the Owner Trustee is not in violation of any of the terms
        of the Participation  Agreement or of any other Transaction  Document to
        which it is a party.

                  (5) To the  best of our  knowledge,  but  without  independent
        investigation,  there is no action,  suit,  investigation  or proceeding
        pending,  or to our  knowledge,  threatened  against FNB (in either such
        capacity) before any court, arbitrator or administrative or governmental
        body  and  which   relates  to  its  banking  or  trust  powers   which,
        individually or in the aggregate,  if decided adversely to the interests
        of FNB (in either such capacity),  would have an adverse effect upon the
        ability of FNB (in either  such  capacity)  to perform  its  obligations
        under the Participation  Agreement or any other Transaction  Document to
        which it is a party (in any capacity).

                  (6)  Neither the  execution  by FNB (in any  capacity)  of the
        Participation   Agreement,   the  Initial   Series  Note  or  any  other
        Transaction  Document to which it (in any capacity) is a party,  nor the
        performance in any capacity by it of its  obligations  thereunder,  will
        subject the Trust Estate or the Lease Indenture  Estate,  or any portion
        thereof, to any Owner Trustee's Lien.

        services in  connection  with the  performance  of its duties  under the

To Each Person Listed on The Attached Schedule

                 SALE AND LEASEBACK OF AN UNDIVIDED INTEREST IN
                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Gentlemen:

                We have  acted  as  special  NRC  counsel  for  Burnham  Leasing
Corporation, a New York corporation (the Owner Participant),  in connection with
the transactions contemplated by the Participation Agreement, dated as of August
12, 1986, (the Participation Agreement),  among the Owner Participant, The First
National Bank of Boston,  a national  banking  association,  individually and as
Owner  Trustee (the Owner  Trustee),  First PV Funding  Corporation,  a Delaware
corporation, Chemical Bank, a New York banking corporation, as Indenture Trustee
and  Public  Service  Company  of New  Mexico,  a New  Mexico  corporation.  All
capitalized  terms used herein and not otherwise  defined  herein shall have the
meanings set forth in Appendix A to the Participation Agreement. This opinion is
being delivered pursuant to Section 11(a)(18) of the Participation Agreement.

                The Owner  Participant  and Owner  Trustee  have  requested  our
opinion with respect to three related  issues:  (1) whether the NRC Order issued
December  12,  l986,  by  the  Nuclear  Regulatory  Commission  ("NRC"),   which
authorizes PNM to proceed with the proposed  transaction  without  requiring the
Owner  Participant  or Owner Trustee to become NRC licensees  during the term of
the Facility Lease of the Undivided Interest,  is a final order; (2) whether the
Owner  Participant  or Owner  Trustee  would  have any  licensing  or  reporting
obligations  during  the  Lease  Term  under  any  nuclear-related   statute  or



6091.BURNHAM.1106.08:1


<PAGE>

regulation;  and (3) whether the  Price-Anderson  Act, 42 U.S.C.  5 2210,  would
protect the Owner  Participant and Owner Trustee against  liability with respect
to any  "nuclear  incident"  (as  defined by the Act) and  whether the Act would
impose any  financial  obligations  on the Owner  Participant  and Owner Trustee
during the lease term.

                  In reaching the  opinions on these issues set forth below,  we
have  reviewed  and  relied  upon the NRC  Order and the  SECY-85-367  NRC staff
document to which the NRC Order refers.  We also have reviewed PNM's Application
to the NRC for approval of the  transaction and various  materials  submitted in
support of that Application,  including the Arizona Nuclear Power Plant ("ANPP")
Project Participation  Agreement and Amendment No. 10 thereto.  Finally, we have
reviewed  successive  drafts  (dated  _____,  _____  and  _____ of the  relevant
transaction documents, in particular the Participation Agreement among the Owner
Participant,  Owner Trustee PNM and others,  Appendix A thereto  (Definition  of
Terms)'  and the  Facility  Lease  between  the Owner  Trustee  and PNM. We have
assumed for purposes of our opinions that the final versions of these  documents
will not differ materially from the _________ draft versions.


                The Finality of the NRC Order

                The NRC Order  constitutes  final agency action,  pursuant to 42
U.S.C. 2239(a), on PNM's application for a license amendment.  The Hobbs Act, 28
U.S.C.  ss. 2344,  permits any party aggrieved" by the NRC Order to petition for
review in the appropriate  court of appeals within sixty (60) days of its entry.
Since no person  intervened in the NRC  proceeding to oppose PNM' 5 application,
however,  an  appeal  from  the  Order by any  person  other  than PNM  would be
dismissed on standing  grounds.  E.g.,  American Civil Liberties Union v F.C.C.,
774 F.2d 24, 25 (1st Cir. 1985) ("The courts have  consistently  interpreted the
term "party  aggrieved" to require that a petitioner  have  participated  in the
agency proceedings"); Gage v. AEC, 479 F.2d 1214, 1218 (D.C. Cir. 1973).

                Section 2.206 of the NRC Rules of Practice (l0 C.F.R. ss. 2.206)
provides that "[a]ny person may file a request for [the  appropriate NRC office]
to institute a proceeding  pursuant to ss. 2.202 to modify,  suspend or revoke a



                                       -2-

<PAGE>

license,  or for such other action as may be appropriate."  This provision would
permit any person to request  the NRC during the term of the  Facility  Lease to
reconsider  its Order and amend the  License so as to add the Owner  Participant
and Owner  Trustee as  licensees.  The  likelihood  that such a request would be
filed, or that if filed it would be granted,  appears to be extremely remote. In
any event, this would not affect the "finality" of the NRC Order.

                Similarly,  Section  2.204 of the Rules of  Practice  (10 C.F.R.
2.204)  authorizes  the NRC to take action of its own accord to modify a license
"by issuing an amendment on notice to the licensee  that the licensee may demand
a hearing with respect to all or any part of the  amendment."  It seems  equally
unlikely  that the NRC would take such  action  during the Lease Term to add the
Owner Participant or Owner Trustee as a licensee of the Palo Verde facility.


                License and Reporting Obligations of the Owner Participant and
Owner Trustee

                The NRC Order includes the condition  requested by PNM that "the
lessor and anyone else who may acquire an interest under the  transaction  which
is the subject of this  application are prohibited  from exercising  directly or
indirectly  any control over the licensees of the Palo Verde nuclear  facility,"
and therefore concludes that the proposed sale-leaseback transaction "shall have
no  effect  on the  Palo  Verde  nuclear  facility  throughout  the  term of the
license."  The  SECY-85-367  staff  recommendation  adopted by the Order further
states:


                [W]here as here,  the sale of the facility is simply a step in a
        transaction  involving only the  refinancing  of capital,  and where the
        investor  owner  only  serves in a passive  role  with no  authority  or
        control  over  the  nuclear  facility,  the  Staff  can  perceive  of no
        regulatory purpose which would be served by an interpretation of Section
        101  of the  Atomic  Energy  Act  the  source  of  the  NRC's  licensing
        authority], which requires the licensing of such financial investors.

6091.BURNHAM.1106.08:1


<PAGE>


                The effect of this  analysis and the NRC Order is that the Owner
Participant  and Owner Trustee are not required to become  licensees  during the
Lease Term and  therefore  will incur no  obligations  as licensees  during that
period.  By the same token, we believe that the Arizona Public Service  Company,
as Project Manager and Operating Agent under the ANPP  Participation  Agreement,
and PNM, as lessee of the undivided interest from the Owner Trustee, will remain
during the Lease Term the relevant  licensees under Facility  Operating  License
No. NPF-51 subject to all license obligations with respect to the management and
operation  of  the  PVNGS.  Such  license  obligations  include  the  costs  and
responsibilities of decommissioning the facility.

                  In addition,  it is our opinion that the Owner Participant and
Owner Trustee will have no reporting obligations during the Lease Term under any
nuclear-related   law  or  regulation.   With  one  exception,   such  reporting
obligations  are limited to  licensees  or holders of  construction  permits for
nuclear  facilities.  The exception is Section 206 of the Energy  Reorganization
Act of 1974, 42 U.S.C.  5846, which provides that each director and "responsible
officer"  of  any  firm  "constructing,  owning,  operating,  or  supplying  the
components of any facility or activity which is licensed or otherwise regulated"
by the NRC, "who obtains information reasonably indicating that such facility or
activity or basic  components  supplied to such  facility"  fails to comply with
nuclear laws or regulations relating to substantial safety hazards or contains a
defect that could create a substantial  safety hazard,  shall immediately notify
the NRC of the failure to comply or the defect."  Although the literal  language
of Section 206 would encompass even unlicensed owners of nuclear facilities, the
NRC regulations  implementing this provision (10 C.F.R. Part 21) make clear that
its reporting  requirements.  extend only to licensees  and to firms  (including
directors and responsible  officers thereof) that construct or supply components
to  licensed  facilities.  10  C.F.R.  21.2.  Just as the NRC Order in this case
reflects the agency's understanding that despite the literal language of Section
101 of the Atomic  Energy  Act the sale of an  ownership  interest  in a nuclear
facility does not require  licensing of the passive  investor owner,  Part 21 of
the NRC  Regulations  reflects the  agency's  understanding  that the  reporting
requirements  established  by Section  206 were not  intended  to reach  passive


                                       -4-

investors  or-lenders  and make sense only if applied to those persons  actually
involved in the management operation or construction of a nuclear facility or in
the supply of components  for such  facilities.  Accordingly,  it is our opinion
that  neither  Section 206 nor its  implementing  regulations  would  impose any
reporting  requirements  on the Owner  Participant  or Owner Trustee  during the
Lease Term.


                The Price-Anderson Act

                Section 170 of the  Price-Anderson  Act,  in its  present  form,
requires  "licensees" of nuclear facilities to maintain financial  protection in
specified  amounts  against  liability for "nuclear  incidents" (as that term is
defined in the Price-Anderson Act, 42 U.S.C. 2014(q)), which protection includes
both  mandatory  insurance  coverage  and  retroactive  premium  assessments  of
$5,000,000 per facility for each nuclear incident.  42 U.S.C. 2210(a) & (b). The
Price-Anderson Act also protects all "persons indemnified" against liability for
nuclear incidents beyond the sum of the amount covered by the required financial
protection  and the limits of  indemnification  provided  by the NRC.  42 U.S.C.
2210(e).. The Act defines the term "persons indemnified" to include both persons
who are required to maintain financial  protection,  i.e.,  licensees,  and "any
other person who may be liable for public  liability."  42 U.S.C.  2014(t).  The
term public liability," in turn, is defined to mean "any legal liability arising
out of or  resulting  from a nuclear  incident"  (emphasis  added),  except  for
workers'  compensation claims of persons employed at the site where the incident
occurs,  claims arising out of an act of war, and claims  relating to loss of or
damage  to  property  located  at the  site of and used in  connection  with the
activity where the incident occurs. 42 U.S.C. 2014(w).

                In light of the NRC Order  holding that PNM remains the licensee
of the Palo Verde  facility  during the lease  term,  in our  opinion  the Owner
Participant  and Owner Trustee will have no obligation  under the Price Anderson
Act or its implementing  regulations to maintain financial protection during the
lease  term.  In  addition,  the terms of the Act  described  above  extend full
financial  protection  to  the  Owner  Participant  and  Owner  Trustee  against
liability for nuclear incidents.

<PAGE>


                In summary,  it is our opinion  that:  (1) the NRC Order  issued
December 12, 1985, is final subject only to  reconsideration  at the instance of
the NRC or some other person under  Sections  2.204 and 2.206 of the NRC'S Rules
of Practice;  (2) under the terms of the NRC Order and under a proper reading of
Section 101 of the Atomic Energy Act and its  implementing  regulations in their
present form, the Owner  Participant and Owner Trustee will not have any license
or reporting  obligations during the lease term under any nuclear-related law or
regulation;  and (3) the  Price-Anderson  Act in its present  form  protects the
Owner  Participant  and  Owner  Trustee  against  financial  exposure  from  any
liability for nuclear  incidents and does not require the Owner  Participant  or
Owner  Trustee to maintain  financial  protection  during the lease term against
liability for such nuclear incidents.


                                            Sincerely,

Dear Sirs:

                We have acted as special  counsel for Public Service  Company of
New Mexico, a New Mexico  corporation (PNM), in connection with the transactions
contemplated by the  Participation  Agreement,  dated as of August 12, 1986 (the

terms used herein and not otherwise  defined  herein shall have the meanings set
forth in  Appendix  A to the  Participation  Agreement.  This  opinion  is being
delivered pursuant to Section 11(a) (20) of the Participation Agreement.

                  As  such  counsel  we  have  examined   originals  or  copies,
certified  or  otherwise  identified  to our  satisfaction,  of  such  corporate
records,   agreements   and   other   instruments,    certificates,    opinions,
correspondence  with public  officials,  certificates  of  officers,  management

                Based on the  foregoing  and subject to the  qualifications  set
forth below, we are of the opinion that:

                (1) The  Participation  Agreement  and  each  other  Transaction
        Document to which PNM is a party have been duly  executed and  delivered
        by PNM,  and,  assuming the due  authorization,  execution  and delivery
        thereof by the other parties thereto,  the  Participation  Agreement and
        each other  Transaction  Document to which PNM is a party constitute the
        legal, valid and binding agreements of PNM,  enforceable  against PNM in
        accordance with their respective terms.

                (2) Neither the execution, delivery or performance by PNM of the
        Participation  Agreement  or  any  other  Transaction  Document  or  any
        Financing  Document to which PNM is a party, nor the consummation by PNM
        of the transactions contemplated thereby, nor compliance by PNM with the
        provisions   thereof,   conflicts  with,  or  results  in  a  breach  or
        contravention  of any of the  provisions  of, the  Restated  Articles of
        Incorporation  or By-Laws of PNM, or any Federal or New York  Applicable
        Law.

                  (3) No  Federal  or New York  Governmental  Action  under  any
        Applicable  Law  now in  effect  is  required  in  connection  with  the
        execution, delivery or performance by PNM of, or the consummation by PNM
        of the transactions  contemplated by, the Participation Agreement or any
        other Transaction  Document in effect on the date hereof to which PNM is
        a party,  except such Federal and New York  Governmental  Actions (i) as

        as may be required in  consequence  of any  transfer of ownership of any
        Note or Bond by the Holder thereof, the beneficial interest in the Trust
        by the Owner Participant, or the Undivided Interest or the Real Property

        Applicable  Law if,  after  termination  or  expiration  of the Facility
        Lease, PNM should provide transmission services for the Owner Trustee or

        the consummation of the transactions  contemplated by the  Participation
        Agreement,  any other Transaction  Document in effect on the date hereof
        or any  Financing  Document  in effect  on the date  hereof or (b) to be
        obtained by any of such Persons  during the term of the  Facility  Lease
        with  respect to Unit 2 except  such  Federal  or New York  Governmental
        Actions (i) as have been duly obtained,  given or accomplished,  (ii) as
        may be required  by  Applicable  Law not now in effect,  (iii) as may be
        required in consequence of any transfer of ownership of any Note or Bond
        by the Holder thereof, the beneficial interest in the Trust by the Owner
        Participant,  or the Undivided Interest or the Real Property Interest by
        the  Owner  Trustee,  (iv)  as may be  required  in  consequence  of the
        issuance,  sale or exchange  and delivery of or any  obligations  issued
        under and pursuant to any  Collateral  Trust  Indenture  (other than the
        Initial  Series Note),  (v) as would be required by existing  Applicable
        Law upon  termination  or expiration of the Facility Lease in connection
        with taking possession of an interest in Unit 2, (vi) as may be required
        by existing  Applicable  Law if, after  termination or expiration of the
        Facility Lease, PNM should provide  transmission  services for the Owner
        Trustee or cease to be agent for the Owner Trustee as provided under the
        Assignment and Assumption, or (vii) as may be required in consequence of
        any  exercise  of  remedies  or  other  rights  by any  such  Person  in
        connection with taking possession of an interest in Unit 2.

                (4) So long as the  Facility  Lease is in effect,  assuming  the
        proper  filing of Form U-7D with the SEC on or within 30 days  after the

        date  hereof,  under  Federal  law  now  in  effect,  neither  the  Loan
        Participant, the Owner Participant, FNB nor the Owner Trustee will be or
        become,  solely by reason of either its entering into the  Participation
        Agreement  or any other  Transaction  Document to which any of them is a
        party, or the transactions  contemplated thereby,  subject to regulation
        (including,  without  limitation,  as an electric  utility  company,  an
        electric  utility,  a  public-utility  company or corporation,  a public
        utility,  a  holding  company,  a public  utility  holding  company,  an
        electric  corporation,  or a  utility  company  or  corporation)  by any
        Federal or New York public utility  commission or other regulatory body,
        authority  or  group  (including,  without  limitation,  the SEC and the
        FERC).  PNM is not a "holding  company" or a  "subsidiary  company" of a
        "holding  company" or an "affiliate" of a "holding  company"  within the
        meaning of the Holding Company Act.

                (5)  PNM  is  not  an   "investment   company",   or  a  company
        "controlled"  by an  "investment  company",  within  the  meaning of the
        Investment Company Act.

                The opinions  set forth above are subject to the  qualifications
that (i) enforceability of the Participation Agreement and the other Transaction
Documents to which PNM is a party in accordance with their  respective terms may
be  limited  by  bankruptcy,  insolvency,  reorganization,  moratorium  or other
similar laws affecting  enforcement of creditors' or lessors' rights  generally,
as well as the general  principles of equity and the  availability  of equitable
remedies,   and  (ii)  certain  laws  and  judicial  decisions  may  affect  the
enforceability  against  PNM of certain  rights  and  remedies  provided  in the
Transaction Documents. With respect to the latter qualification, however, we are
of the  opinion  that none of such laws now in effect and none of such  judicial
decisions make the rights and remedies  provided in the  Transaction  Documents,
taken  as a  whole,  inadequate  for  the  realization  of the  benefits  of the
Transaction Documents.

                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Dear Sirs:

                  We have acted as general counsel for Public Service Company of
New Mexico, a New Mexico  corporation (PNM), in connection with the transactions
contemplated by the  Participation  Agreement,  dated as of August 12, 1986 (the
Participation  Agreement),   among  Burnham  Leasing  Corporation,  a  New  York
corporation, as Owner Participant, The First National Bank of Boston, a national
banking  association,  individually  and as  Owner  Trustee,  First  PV  Funding
Corporation,  a  Delaware  corporation,   Chemical  Bank,  a  New  York  banking
corporation,  as Indenture  Trustee,  and PNM. All capitalized terms used herein
and not otherwise defined herein shall have the meanings set forth in Appendix A
to the  Participation  Agreement.  This opinion is being  delivered  pursuant to
Section 11(a) (21) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.




6091.BURNHAM.1106.08:1


<PAGE>


                Based on the foregoing, we are of the opinion that:

                (1) PNM is a corporation  duly organized and validly existing in
        good  standing  under  the laws of the State of New  Mexico  and has the
        corporate  power and  authority  to carry on its  business as  presently
        conducted,  to own or hold under lease its  properties and to enter into
        and perform its  obligations  under the  Participation  Agreement,  each
        other  Transaction  Document to which PNM is a party, and each Financing
        Document  to which  PNM is a party.  PNM is duly  qualified  and in good
        standing to do business as a foreign corporation in the State of Arizona
        and has not failed to qualify to do business  or to be in good  standing
        in any other  jurisdiction  where  failure  so to  qualify or be in good
        standing would materially and adversely  affect the financial  condition
        of PNM or its  ability  to  perform  any of its  obligations  under  the
        Participation  Agreement, any other Transaction Document to which PNM is
        a party, or any Financing Document to which PNM is a party.

                (2)  The  execution,  delivery  and  performance  by  PNM of the
        Participation Agreement, each other Transaction Document to which PNM is
        a party,  and each Financing  Document to which PNM is a party have been
        duly authorized by all necessary corporate action on the part of PNM and
        do not require the consent or approval of the stockholders of PNM or any
        trustee or holder of any  indebtedness or other obligation of PNM, other
        than  (i)  the   Mortgage   Release,   (ii)  the  finding  of  the  ANPP
        Administrative  Committee  described  in  Section  15.6.2  of  the  ANPP
        Participation  Agreement, and (iii) such other consents and approvals as
        have been duly obtained, given or accomplished.

                (3) The Participation Agreement, each other Transaction Document
        to which PNM is a party,  and each Financing  Document to which PNM is a
        party have been duly executed and  delivered by PNM,  and,  assuming the
        due  authorization,  execution and delivery thereof by the other parties
        thereto,  the  Participation  Agreement,  each  such  other  Transaction
        Document and each such Financing  Document  constitutes the legal, valid
        and binding agreement of PNM, enforceable against PNM in accordance with
        their respective terms.

6091.BURNHAM.1106.08:1


<PAGE>


                (4) Neither the execution, delivery or performance by PNM of the
        Participation  Agreement, any other Transaction Document to which PNM is
        a party,  or any  Financing  Document  to which PNM is a party,  nor the
        consummation  by PNM  of  the  transactions  contemplated  thereby,  nor
        compliance  by PNM with  the  provisions  thereof,  conflicts  with,  or
        results in a breach or  contravention  of any of the  provisions of, the
        Restated Articles of Incorporation or By-Laws of PNM or any Affiliate of
        PNM, or any  Applicable  Law, or any indenture,  mortgage,  lease or any
        other  agreement  or  instrument,  known  to  us,  to  which  PNM or any
        Affiliate  of PNM is a party  or by  which  the  property  of PNM or any
        Affiliate of PNM is bound,  or results in the creation or  imposition of
        any Lien (other than  Permitted  Liens) upon any  property of PNM or any
        Affiliate of PNM.

                (5) No New Mexico  Governmental  Action under Applicable Law now
        in effect is  required in  connection  with the  execution,  delivery or
        performance by PNM of, or the  consummation  by PNM of the  transactions
        contemplated  by, the  Participation  Agreement,  any other  Transaction
        Document to which PNM is a party, or any Financing Document to which PNM
        is a party, except such New Mexico Governmental Actions (i) as have been
        duly obtained, given or accomplished,  and (ii) as may be required under
        existing New Mexico Applicable Law to be obtained, given or accomplished
        from  time  to time  after  the  date  hereof  in  connection  with  the
        maintenance,  use,  possession or operation of Unit 2 or otherwise  with
        respect to Unit 2 and PNM's  involvement  therewith  and which are,  for
        PVNGS, routine in nature and which we have no reason to believe will not
        be timely obtained. No New Mexico Governmental Action is required (a) in
        connection with the  participation  by the Owner Trustee,  the Indenture
        Trustee,   the  Owner   Participant  or  the  Loan  Participant  in  the
        consummation  of the  transactions  contemplated  by  the  Participation
        Agreement,  any other Transaction  Document in effect on the date hereof
        or any  Financing  Document  in effect  on the date  hereof or (b) to be
        obtained by any of such Persons  during the term of the  Facility  Lease
        with respect to Unit 2 except such New Mexico  Governmental  Actions (i)
        as have  been  duly  obtained,  given  or  accomplished,  (ii) as may be
        required by Applicable  Law not now in effect,  (iii) as may be required

        in consequence of any transfer of ownership of the Undivided Interest or
        the  Real  Property  Interest  by the  Owner  Trustee,  (iv) as would be
        required by existing  Applicable  Law upon  termination or expiration of
        the Facility Lease in connection  with taking  possession of an interest
        in Unit 2, (v) as may be required by existing  Applicable  Law if, after
        termination  or expiration  of the Facility  Lease,  PNM should  provide
        transmission services for the Owner Trustee or cease to be agent for the
        Owner Trustee as provided under the Assignment and  Assumption,  or (vi)
        as may. be required in  consequence of any exercise of remedies or other
        rights by any such Person in  connection  with taking  possession  of an
        interest in Unit 2.

                (6) Except as disclosed  in the  financial  statements  to which
        reference is made in Section  l0(a)(ll) of the  Participation  Agreement
        and in the reports to which  reference is made in Section 10 (a) (12) of
        the Participation Agreement,  there is no action, suit, investigation or
        proceeding  pending or, to our knowledge,  threatened against PNM before
        any  Federal  or New  Mexico  court,  arbitrator  or  administrative  or
        governmental  body which questions the validity or enforceability of the
        Participation  Agreement  or  any  other  Transaction  Document  or  any
        Financing  Document in effect on the date hereof or which,  individually
        or in the aggregate, if decided adversely to the interests of PNM, would
        have a material adverse effect on the business or financial condition of
        PNM or materially and adversely affect the ability of PNM to perform its
        obligations under the  Participation  Agreement or any other Transaction
        Document or any Financing Document in effect on the date hereof to which
        PNM is a party.

                (7)  The  lien of the  Existing  Mortgage  does  not  extend  to
        contract rights of PNM under the Transaction  Documents  (other than the
        Facility  Lease) or to the Generation  Entitlement  Share related to the
        Undivided Interest.

                The opinions  set forth above are subject to the  qualifications
that (i)  enforceability of the Participation  Agreement,  the other Transaction
Documents to which PNM is a party, and the Financing Documents to which PNM is a
party in accordance  with their  respective  terms may be limited by bankruptcy,

insolvency,   reorganization,   moratorium  of  other  similar  laws   affecting
enforcement of creditors' or lessors' rights  generally,  as well as the general
principles  of equity  and the  availability  of  equitable  remedies,  and (ii)
certain laws and judicial  decisions  may affect the  enforceability  of certain
rights and remedies provided in the Transaction  Documents.  With respect to the
latter qualification,  however, we are of the opinion that none of such laws now
in effect and none of such  judicial  decisions  make the  rights  and  remedies
provided  in  the  Transaction  Documents,  taken  as a  whole,  inadequate  for
enforcing  payment of the Initial Series Note and the security interest provided
by  the  Indenture  or  the  realization  of the  benefits  of  the  Transaction
Documents.

                In rendering the opinions set forth above,  we have relied as to
all matters  relating  to (A) the law of the State of New York,  solely upon the
opinion of Mudge Rose  Guthrie  Alexander  & Ferdon,  Special  Counsel  for PNM,
delivered pursuant to Section 11(a) (20) of the Participation  Agreement,  as to
which law we have, with your consent, made no independent investigation, (B) the
laws of the State of Arizona,  the Atomic  Energy Act and the Nuclear Waste Act,
solely  upon the  opinion  of Snell & Wilmer,  PNM's  Special  Arizona  Counsel,
delivered pursuant to Section 11(a) (22) of the Participation  Agreement,  as to
which we have, with your consent, made no independent investigation, and (C) the
Federal Power Act, upon the opinion of Newman & Holtzinger,  P.C., PNM's Special
FERC  Counsel,  delivered  pursuant to Section  11(a) (23) of the  Participation
Agreement,  as to  which  we  have,  with  your  consent,  made  no  independent
investigation. Each such opinion is satisfactory to us in form and scope, and we
believe you and we are justified in relying thereon.

                For  purposes  of this  opinion we have  assumed  that the Owner
Participant and the Lessor will exercise their rights, and that PNM will perform
its  obligations,  under  Section  13(c) of the  Facility  Lease  if it  becomes
necessary to do so to remain in compliance  with the New Mexico  Order.  We have
further  assumed  that no Lease  Transaction  (as  that  term is used in the New
Mexico Order) entered into by PNM subsequent to the date hereof will result in a
violation of the New Mexico Order.

above,  we have not passed upon and do not purport to pass upon the  application

                 SALE AND LEASEBACK OF AN UNDIVIDED INTEREST IN
                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Dear Sirs:

                We have  acted as Special  Arizona  counsel  for Public  Service
Company of New Mexico,  a New Mexico  corporation  (PNM), in connection with the
transactions contemplated by the Participation Agreement, dated as of August 12,
1986 (the Participation  Agreement),  among Burnham Leasing  Corporation,  a New
York  corporation,  as Owner  Participant,  The First National Bank of Boston, a
national banking association (FNB),  individually and as Owner Trustee, First PV
Funding Corporation,  a Delaware corporation,  Chemical Bank, a New York banking
corporation,  as Indenture  Trustee,  and PNM. All capitalized terms used herein
and not otherwise  defined herein shall have the meaning set forth in Appendix A
to the  Participation  Agreement.  This opinion is' being delivered  pursuant to
Section 11(a) (22) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.




6091.BURNHAM.1106.08:1.


<PAGE>


                In rendering  our  opinions,  we have also  reviewed the Special
Order of Exemption,  issued December 26, 1985, by the Arizona Department of Real
Estate  with  respect to PVNGS,  together  with two (2) Snell & Wilmer  petition
letters to the Arizona  Department of Real Estate,  dated  December 19, 1985 and
December 23, 1985 (the Special Order of Exemption and the petition letters being
collectively referred to herein as the "Exemption Documents").

                In rendering our opinions,  we have relied as to certain factual
matters on the documents we have examined,  on certificates of public officials,
and on the Certificate attached as Exhibit A, and we have assumed:

                (1) Lessee is a corporation  duly organized and validly existing
        in good  standing  under the laws of the State of New Mexico and has the
        corporate  power and  authority  to carry on its  business as  presently
        conducted,  to own or hold under lease its  properties and to enter into
        and perform its obligations under each Transaction  Document to which it
        is a party.

                (2) The  execution,  delivery and  performance by Lessee of each
        Transaction Document to which it is a party have been duly authorized by
        all  necessary  corporate  action on the part of Lessee and do not,  and
        will not, require the consent or approval of the stockholders of Lessee.

                (3) Each  Transaction  Document  to which  Lessee is a party has
        been duly  executed and delivered by Lessee,  and each such  Transaction
        Document  (excluding  the Facility  Lease) to which Lessee is a party is
        the legal, valid and binding obligation of Lessee,  enforceable  against
        Lessee in accordance with its terms.

                (4) Each party to each Transaction Document,  other than Lessee,
        is duly  organized and validly  existing in good standing under the laws
        of the jurisdiction of its organization, is duly registered, licensed or
        authorized to transact business in each other jurisdiction in which such
        registration,  licensing or authorization is required, and has the power
        and the  authority  to enter into and to perform its  obligations  under
        each Transaction 'Document to which it is a party.

                (5) The  execution,  delivery and  performance  by each party to
        each Transaction Document,  other than Lessee, have been duly authorized
        by all necessary  action by such party and do not require the consent or
        approval  of any of the  stockholders  of such party.  Each  Transaction
        Document  has been duly  executed and  delivered by each party  thereto,
        other  than  Lessee,  and  constitutes  the  legal,  valid  and  binding
        obligation of such party,  enforceable  against such party in accordance
        with its terms.

                (6) The trusts of which the Owner Trustee, the Indenture Trustee
        and the Collateral  Trust Trustee are the Owner  Trustee,  the Indenture
        Trustee and the Collateral Trust Trustee, respectively, were duly formed
        and are validly  existing under the laws of the  jurisdiction  governing
        such trusts.  Each of the Owner Trustee,  the Indenture  Trustee and the
        Collateral  Trust  Trustee has the power and  authority  under the trust
        agreement  for its  respective  trust to  enter  into  and  perform  its
        obligations under each Transaction Document to which it is a party.

                (7)  The  execution,  delivery  and  performance  by  the  Owner
        Trustee, the Indenture Trustee, and the Collateral Trust Trustee of each
        Transaction  Document to which it is a party are authorized by the trust
        agreement  of its  respective  trust and do not  require  the consent or
        approval of any other  Person.  Each  Transaction  Document to which the
        Owner Trustee,  the Indenture Trustee or the Collateral Trust Trustee is
        a party has been duly executed and delivered by the Owner  Trustee,  the
        Indenture  Trustee or the Collateral  Trust Trustee,  respectively,  and
        constitutes  the  legal,  valid  and  binding  obligation  of the  Owner
        Trustee,   the  Indenture  Trustee  or  the  Collateral  Trust  Trustee,
        respectively,  enforceable  against  the Owner  Trustee,  the  Indenture
        Trustee or the  Collateral  Trust Trustee,  respectively,  in accordance
        with its terms.

                (8) Lessee's past, present and proposed  activities in the State
        of  Arizona  (including,  without  limitation,  Lessee's  ownership  and
        operation of electrical  facilities in the State of Arizona) consist of,
        and are limited to, Lessee's ownership of an undivided interest in PVNGS
        (including the plant site) the ANPP Switchyard and associated

       transmission  facilities  therefor,  and its  ownership  interest in, and
       operation of a certain portion of, certain transmission lines, facilities
       and control  equipment  located on real  property  owned by Lessee and/or
       other  corporations  and  on  easements  owned  by  Lessee  and/or  other
       corporations  in Greenlee  County,  Arizona.  Lessee is not  making,  nor
       presently  proposing to make,  any sales of  electricity  in the State of
       Arizona (other than sales to or exchanges with other electric  generating
       or distributing entities).

                (9) The Owner Participant,  FNB, (in its individual capacity and
        as the Owner Trustee), and the Indenture Trustee, and each of them, will
        not, by reason either of entering into the Participation  Agreement, the
        Facility  Lease,  the Assignment and Assumption,  the Indenture,  or any
        other   Transaction   Document,   consummation   of   the   transactions
        contemplated  thereby or  otherwise,  engage in any  activity in Arizona
        involving the ownership  and operation of electrical  facilities,  other
        than those presently  conducted by the Lessee, as set forth in Paragraph
        8 above;

                (10)  Immediately  prior to the  execution  and  delivery of the
        Transaction  Documents,  Lessee owned the property to be  transferred by
        Lessee to Owner Trustee  under the  Transaction  Documents.  Immediately
        after the execution  and delivery of the  Transaction  Documents,  Owner
        Trustee  will own the  property to be  transferred  by the Lessee to the
        Owner Trustee under the Transaction  Documents.  The assumptions in this
        Paragraph  10 do not  apply to the  opinion  in the  first  sentence  of
        Section 9 of this legal opinion.

                (11) Amendment Number 10 to the ANPP Participation Agreement has
        been duly authorized,  executed and delivered by, constitutes the legal,
        valid and binding agreement of, and is enforceable against,  each of the
        parties  thereto.  The  transactions  contemplated  by  the  Transaction
        Documents are authorized and permitted to be performed  pursuant to, and
        do not  conflict  with,  the terms and  conditions  of any ANPP  Project
        Agreement,  including,  without  limitation,  Amendment Number 10 to the
        ANPP Participation Agreement.

                (12) The sale and conveyance of the Undivided Interest, the Real
        Property  Interest  and any  other  property  or  interest  in  property
        transferred  by Lessee under the  Transaction  Documents will not render
        Lessee  insolvent  nor is it being  made in  contemplation  of  Lessee's
        insolvency;  the  property  remaining  in the hands of Lessee after such
        sale,  conveyance  and transfer is not an  unreasonably  small  capital;
        Lessee does not intend to or believe that it will incur debts beyond its
        ability  to pay as they  mature;  and  Lessee  has no  actual  intent to
        hinder, delay or defraud either present or future creditors.

                (13) On the date of execution of the  Transaction  Documents and
        on the date hereof,  there was adequate  consideration for the execution
        and  delivery by Lessee of the  Transaction  Documents  to which it is a
        party and for Lessee  entering  into the  transaction  described  in the
        Transaction Documents.

                (14) The chief executive office and the place of business of the
        Lessee and the office where it keeps its records concerning its accounts
        or  contract  rights  is  located  at  Alvarado  Square,   Albuquerque,.
        Bernalillo County, New Mexico 87158.

                (15) The  Transaction  Documents  accurately  and completely set
        forth all agreements,  arrangements  and  understandings  of the parties
        thereto with respect to the transaction described in and contemplated by
        the Transaction  Documents and the Transaction  Documents accurately and
        completely  reflect the  intentions  of the parties with respect to such
        transaction.

                  (16) The  Facility  Lease is a "lease" for Federal  income tax
         purposes  and an  "operating  lease"  and  not a  "capital  lease"  for
         financial reporting purposes under Financial Accounting Standards Board
         Statement 13 and will be so treated and  reported for such  purposes by
         Lessee and Owner Trustee.

                (17)  The  form  of  the  Transaction   Documents  executed  and
        delivered  by  the  parties  thereto  conforms  to  the  drafts  of  the
        Transaction Documents described above.

                Based on the  foregoing  and subject to the  qualifications  set
        forth herein, we are of the opinion that:

                (1) Lessee is  authorized  to transact  business  and is in good
        standing as a foreign  corporation under the General  Corporation Law of
        the State of  Arizona,  Chapter 1, Title 10,  Arizona  Revised  Statutes
        ("A.R.S.").

                (2) Lessee has the power and  authority,  and is not required to
        obtain any  franchises,  licenses or permits not  already  obtained,  to
        engage  in the State of  Arizona  in the  business  and  activities  now
        conducted  by  it  therein,   except  that  certain  minor  defects  and
        exceptions may exist which,  individually and in the aggregate, are not,
        in our judgment, material.

                (3) Lessee is not a public utility or public service corporation
        under Arizona Applicable Law.

                (4) Under Arizona Applicable Law the Owner Participant,  FNB (in
        its individual capacity and as Owner Trustee) and each of them, will not
        be, by reason of entering into any Transaction  Document or by reason of
        the activities  contemplated by the  Transaction  Documents prior to the
        expiration or termination of the Facility  Lease,  subject to regulation
        as a public  service  corporation,  public  utility,  or public  utility
        holding  company  by any  Arizona  public  utility  commission  or other
        Arizona  regulatory  body,   authority  or  group  (including,   without
        limitation, the Arizona Corporation Commission),  provided,  however, we
        express no opinion regarding the effect of (i) Applicable Law not now in
        effect,  (ii) any transfer of ownership of the Undivided Interest by the
        Owner Trustee, (iii) termination or expiration of the Facility Lease and
        the taking of  possession by the Owner Trustee or any other Person of an
        interest in Unit 2, (iv) Lessee's providing of transmission  services to
        the Owner Trustee or any other Person  owning the Undivided  Interest or
        the Real  Property  Interest,  or (v) any  exercise of remedies or other
        rights by any Person in connection with taking possession of an interest
        in Unit 2.

                (5) All  Governmental  Action  by the  State of  Arizona  or any
        political  subdivision thereof which is or will be required on or before
        the date hereof in connection  with the execution and delivery by Lessee
        of  each  Transaction  Document  to  which  Lessee  is a  party  and  in
        connection  with the  performance by Lessee of those of its  obligations
        pursuant to any  Transaction  Document to which  Lessee is a party which
        are to be  performed  on or  before  the date  hereof,  have  been  duly
        obtained, given or accomplished, except that our opinion in this Section
        5 does not relate to (i) any governmental  Action required in connection
        with construction, improvement, maintenance, use, possession, operation,
        decommissioning  or retirement  from service of any portion of Unit 2 or
        PVNGS or  otherwise  with  respect to Unit 2 or PVNGS or Lessee's or the
        Operating Agent's involvement therewith, Lessee's duties and obligations
        as a Participant under any of the ANPP Project  Agreements,  or Lessee's
        duties and  obligations as Agent under the  Assignment  and  Assumption;
        (ii) securities and taxation laws of any Arizona Governmental Authority;
        and (iii) the recording or filing of any Transaction Document;  and (iv)
        the  transfer  of the  "Assigned  Project  Agreements"  (as that term is
        defined in the Deed) pursuant to the Deed.

                (6) The execution,  delivery and  performance of the Transaction
        Documents by the parties  thereto do not violate the Atomic  Energy Act,
        as now in effect,  the NRC regulations  now in effect,  any order of the
        NRC now in effect, or the Nuclear Waste Act, as now in effect,  provided
        that such parties  comply with the terms and  conditions  of the License
        and the NRC Order. No Governmental  Action by or with respect to the NRC
        is or will be required in  connection  with the  execution,  delivery or
        performance  by  Lessee of the  Participation  Agreement,  the  Facility
        Lease, the Assignment and Assumption or any other  Transaction  Document
        to which it is a party,  except (i) such Governmental  Actions as may be
        required  pursuant to the terms of the License;  (ii) such  Governmental
        Actions as may be required pursuant to the terms of the NRC Order; (iii)
        such other  Governmental  Actions by or with  respect to the NRC as have
        been duly obtained,  given or accomplished on or before the date hereof;
        (iv) such  Governmental  Actions of or with respect to the NRC as may be

        required  under  existing law or  regulation  to be  obtained,  given or
        accomplished from time to time after the Closing Date in connection with
        the construction,  improvement,  maintenance, operation, decommissioning
        or  retirement  from  service  of any  portion  of  Unit 2 or  PVNGS  or
        otherwise  with respect to Unit 2 or PVNGS and Lessee's or the Operating
        Agent's involvement  therewith;  and (v) such other Governmental Actions
        as may be required under law or regulation not now in effect.

                (7) The  transfer of property and interest in property by Lessee
        to the Owner Trustee pursuant to the Participation  Agreement,  the Bill
        of  Sale,  the  Deed,  the  Trust  Assignment,  and the  Assignment  and
        Assumption is not a fraudulent  conveyance under the law of the State of
        Arizona,  provided,  however, that this opinion, in so far as it relates
        to  A.R.S.  Section  44-1061  and any  common  law  vendor-in-possession
        fraudulent  conveyance  doctrine,  is subject to the following comments.
        Section 44-1061 provides:

                         "A. A sale made by a vendor of goods  and  chattels  in
                         his  possession or under his control,  or an assignment
                         of goods and chattels, unless the sale or assignment is
                         accompanied by an immediate delivery and followed by an
                         actual and continued change of possession of the things
                         sold or  assigned,  is prima  facie  evidence  of fraud
                         against  creditors  of the vendor,  or creditors of the
                         person making the assignment,  or subsequent purchasers
                         in good faith.

                         "B. The term  'creditors'  includes all persons who are
                         creditors  of the vendor or  assignor at any time while
                         such goods and chattels are in his  possession or under
                         his control."

                The Arizona court decisions  interpreting  Section 44-1061 arose
        in the context of  tangible  property  in the actual  possession  of the
        seller.  These  decisions  suggest  that open,  visible and  unequivocal
        indications that there has been a change


                                       -8-

       of ownership  would be  sufficient to overcome the prima fade evidence of
       fraud established by Section 44-1061. See, e.g., Nolte V. Winstayley,  16
       Ariz. 327, 145 Pac. 246 (1914). Unfortunately, this precedent is not very
       helpful in the context of the present transaction. In addition, the court
       decisions  under  Section  44-1061  are  equivocal  as to the  effect  of
       recording or filing transfer documents.  Nolte V. Winstanley,  supra; and
       Liebes V. Steffy,  4 Ariz. 11, 32 Pac. 261 (1893).  Notwithstanding  this
       equivocation,  as to a subsequent  encumbrancer of any personal  property
       which is subject to Article 9 of the Uniform Commercial Code as in effect
       in  Arizona,  which  is  described  in  the  three  (3)  UCC-1  Financing
       Statements,  dated December 31, 1985 between Lessee, as lessee, and Owner
       Trustee,  as lessor filed with the  Secretary of State of Arizona and the
       County  Recorder,  Maricopa  County,  State of Arizona  (Lease  Financing
       Statements)  and in which a security  interest may be perfected by filing
       of a financing  statement  within Arizona,  we believe that the filing of
       the Lease Financing Statements should be sufficient to overcome the prima
       facie evidence of fraud to the extent the description of such property in
       the  Lease  Financing  Statements  is  accurate,  complete,  and  legally
       adequate.  In addition,  as to future  creditors with actual knowledge of
       the transfers in the Deed, the Bill of Sale, the Trust Assignment and the
       Assignment  and  Assumption  prior to extending or  committing to extend.
       credit,  we believe that such knowledge  should  overcome the prima facie
       evidence of fraud in Section 44-1061.

                (8)  Neither  the  execution  and  delivery  by Lessee,  nor the
        performance  by Lessee,  of any  Transaction  Document  to which it is a
        party, conflicts with, or results in a breach of any statute, ordinance,
        governmental  rule or  regulation  of the State of Arizona  or  Maricopa
        County,  except  that our  opinion  does not relate to any  conflict  or
        breach as a result of (i) construction,  improvement,  maintenance, use,
        possession, operation, decommissioning or retirement from service of any
        portion of Unit 2 or PVNGS or otherwise  with respect to Unit 2 or PVNGS
        or the Lessee's or the operating Agent's involvement therewith, Lessee's
        duties and  obligations  as a Participant  under any of the ANPP Project
        Agreements,  or  Lessee's  duties  and  obligations  as Agent  under the

        Assignment and Assumption;  (ii) Applicable Law not now in effect; (iii)
        securities  and  taxation  laws of any Arizona  Governmental  Authority;
        ((iv) any  Refunding  described  in  Section  2(c) of the  Participation
        Agreement,  any  assumption  by Lessee  pursuant  to Section  3.9 of the
        Indenture or any other similar or related  provision in the Indenture or
        any of the other  Transaction  Documents,  a transfer of the interest in
        the Trust  Estate  pursuant  to  Section  7(b) (4) of the  Participation
        Agreement  and any security  interest  granted  pursuant to said Section
        7(b)(4),  the conversion of the Facility  Lease to a security  agreement
        pursuant  to  Section  9(c),  Section  9(d),  or  Section.  16(e) of the
        Facility  Lease  or any  other  similar  or  related  provisions  in the
        Facility Lease or any of the other Transaction Documents, the subjection
        of the Undivided  Interest or the Real Property  Interest to the lien of
        the  Indenture  pursuant  to Section  9(j) of the  Facility  Lease,  any
        Supplemental  Financing  pursuant to Section 8(f) of the Facility Lease,
        or the  transfer  of the  Assigned  Project  Agreements  pursuant to the
        Deed;] (v) any action taken by Lessee  pursuant to Section  10(b) (2) of
        the   Participation   Agreement   or  any  similar   provision   in  the
        Participation  Agreement  or any other  Transaction  Document;  (vi) any
        involvement  by Lessee in  connection  with any transfer of ownership of
        the  Undivided  Interest  or the Real  Property  Interest  by the  Owner
        Trustee or the taking of  possession  of the  Undivided  Interest or the
        Real  Property  interest  by Owner  Trustee  or any  other  Person  upon
        expiration or termination of the Facility Lease;  (vii) Lessee providing
        transmission  services for the Owner  Trustee or any other Person owning
        the Undivided Interest or the Real Property Interest or ceasing to serve
        as Agent pursuant to the Assignment or Assumption,  (viii) any action by
        Lessee pursuant to Article VI of the Assignment and Assumption,  or (ix)
        Lessor or any other Person, other than Lessee,  receiving the Generation
        Entitlement Share of Lessee pursuant to Section 19 of the Facility Lease
        or any other provision of any Transaction Document.

                 (9) Assuming  that any choice of law  provision in favor of the
        law of a state other than the State of Arizona is  disregarded  therein,
        the Deed,  the Bill of Sale and the  Assignment  and  Assumption  are in
        sufficient  form to convey from Lessee to Owner Trustee the interests in

        property  described therein and for recording under the law of the State
        of  Arizona,  except  that  our  opinion  in  this  sentence  and in the
        remainder  of this  Section  9 does not  relate to the  transfer  of the
        Assigned Project  Agreements  pursuant to the Deed. The Trust Assignment
        is in  sufficient  form to  convey  from  Lessee  to Owner  Trustee  the
        interests in property therein described. The Deed, the Bill of Sale, the
        Assignment  and  Assumption  and the Facility  Lease when duly executed,
        acknowledged  and delivered,  each must be recorded in the Office of the
        Recorder of Maricopa  County,  Arizona,  together  with an [Affidavit of
        Legal Value] pursuant to A.R.S. Section 42-1612 with respect to any such
        document  transferring  title  to real  estate  (other  than  leases  or
        easements).   Precautionary  financing  statements  pursuant  to  A.R.S.
        Section 47-9408 must be filed in the office of the Arizona  Secretary of
        State and the Office of the Recorder of Maricopa County,  Arizona.  Upon
        the  completion  of such  recordings  and filings,  no other  filings or
        recordings in Arizona are required to establish,  preserve, perfect, and
        protect the Owner  Trustee's  rights and interests  (including,  without
        limitation1  any security  interest which may be deemed to be created by
        the  Facility  Lease)  in and to the  Undivided  Interest  and the  Real
        Property  Interest  (other  than the  interests  transferred  under  the
        Assignment of Beneficial  Interest),  and no additional  recordation  is
        required to continue the effectiveness of such recordings, provided that
        our opinion in this  Section 9 is limited to property  constituting  the
        Undivided  Interest and the Real  Property  Interest that is either real
        property  under the law of the State of Arizona or  property  subject to
        Article 9 of the  Uniform  Commercial  Code (as in effect in Arizona) in
        which a security  interest may be perfected by the filing of a financing
        statement  within  the State of  Arizona.  In  addition,  no  additional
        financing statements, other than those filed with the Secretary of State
        of Arizona and in the Office of the County Recorder of Maricopa  County,
        Arizona, are required to be filed in order to continue the effectiveness
        thereof  except that  continuation  statements  are required to be filed
        with respect to such financing  statements  within each of the six-month
        periods  preceding  the  expiration  of each  six-year  period after the
        respective dates of filing. We express no opinion regarding the form

       for  conveyance,  the transfer or the perfection of rights in any Capital
       Improvements  or  regarding  filings or  recordings  that may be required
       under the laws of any other state,  under federal law or by reason of the
       application  of the  conflict  of laws rules set forth in A.R.S.  Section
       47-9103. To the extent any recorded or filed Transaction  Document refers
       to or  incorporates  by reference  any other  Transaction  Document  (for
       definitional  purposes or  otherwise)  not  recorded or filed in the same
       location  or,  if  recorded  [or]  filed,  not  identifying  the date and
       instrument or file number of such document incorporated by reference, our
       opinion in this Section 9 excludes the effect,  if any, of such reference
       or incorporation by reference. In giving our opinion in this Section 9 we
       have assumed that the description of the Undivided  Interest and the Real
       Property Interest in the Lease Financing Statements is accurate, complete
       and legally adequate.

                (10) You have  requested  that we advise you  whether an Arizona
        court would give effect to the choice of law  provision  in favor of the
        law of the State of New York in each  Transaction  Document,  other than
        the Deed,  the Bill of Sale,  the Trust  Assignment,  the Assignment and
        Assumption,  and the  Facility  Lease.  There is no Arizona case stating
        that an Arizona  court will  follow the choice of law  provision  of the
        parties  to a  contract.  However,  the  Supreme  Court of  Arizona  has
        consistently  ruled that where it is not bound by a previous decision or
        by legislative enactment it will follow the rules in the Restatements of
        the Law including the Restatements of Conflict of Laws. Smith v. Normat,
        51 Ariz. 134, 75 P.2d 38 1938);  Western Coal & Min. Co. V. Hilvert,  66
        Ariz. 171, 160 P.2d 331 (1945); and Taylor V. Security National Bank, 20
        Ariz.  App.  504,  514 P.2d 257 (1973).  Section 187 of the  Restatement
        (Second)  Conflict of laws  provides  that the parties to a contract may
        stipulate  to their  choice of law t9 govern the  contract  and that the
        laws of the state chosen will be applied unless (i) the particular issue
        is one  which  the  parties  could  not  have  resolved  by an  explicit
        provision in their agreement directed to that issue, and (ii) either:

<PAGE>

                         "(a) the chosen state has no  substantial  relationship
                         to the parties or the transaction and there is no other
                         reasonable basis for the parties' choice; or

                         "(b)  application  of the law of the chosen state would
                         be  contrary to a  fundamental  policy of a state which
                         has a materially greater interest than the chosen state
                         in the determination of the particular issue and which,
                         under the rule of  Section  188,  would be the state of
                         the  applicable  law in  the  absence  of an  effective
                         choice of law by the parties."

                We  believe  that  the  State  of New  York  has a  "substantial
        relationship"  to the  parties or the  transaction  with  respect to the
        documents covered by the opinion in this Section 9 and that with respect
        to such documents  there is a reasonable  basis for the choice of law of
        the  State  of New York  because  at least  one of the  parties  to such
        documents  is located in the State of New York and such  documents  have
        been substantially  negotiated within and from the State of New York and
        have been executed and delivered within the State of New York. Thus, the
        effectiveness  of the choice of law  provisions in these  documents will
        depend upon whether,  as to the particular issue in question,  (i) there
        would be a difference in the applicable  substantive law of the State of
        New  York,  on the one  hand,  and the law of the  State of  Arizona  or
        another  state1 on the other  hand,  (ii) the  resolution  of such issue
        under  the  law  of the  State  of  New  York  would  be  contrary  to a
        fundamental  policy of the State of Arizona or such other  state,  (iii)
        the State of Arizona or such other state would have a materially greater
        interest  than  the  State  of  New  York  in the  determination  of the
        particular issue and (iv) under Section 188 of the Restatement  (Second)
        Conflict  of Laws,  the law of the State of Arizona or such other  state
        would be the applicable law.

                (11)  Assuming  an Arizona  court were not to give effect to the
        choice of law provision in the Facility Lease in favor of the law of the
        State of New York and  were to  apply  the law of the  State of  Arizona

        (other  than  choice of law  rules),  the  Facility  Lease is the legal,
        valid, and binding obligation of Lessee and is duly enforceable  against
        Lessee in accordance with its terms:

                         (a)  Except  as  limited  by   applicable   bankruptcy,
                insolvency,  moratorium,  reorganization,  and  similar  laws of
                general application;

                         (b)  Except  as  limited  by  equitable  principles  of
                general application; and

                           (c)  Except as limited  by other  applicable  laws or
                general principles of law that may render unenforceable  certain
                provisions of the Facility Lease, provided, however, that (i) if
                Owner  Trustee  does  not  violate  its  obligations  under  the
                Facility Lease (including,  without limitation,  the covenant of
                quiet  enjoyment),  such limitations will not interfere with the
                enforcement by Owner Trustee of the obligations of Lessee to pay
                Basic Rent as provided in Section 3(a) of the Facility  Lease as
                the payments of Basic Rent become due on each Basic Rent Payment
                Date prior to  termination  of the  Facility  Lease and  without
                acceleration  or advancement  thereof and (ii) Owner Trustee may
                obtain  the  return  of the  Undivided  Interest  and  the  Real
                Property interest upon termination or expiration of the Facility
                Lease,  except  in the  case of each  of (i)  and  (ii)  for the
                economic  consequences of any procedural  delays that may result
                from such limitations.

                Anything in this  opinion to the  contrary  notwithstanding,  we
express no opinion  concerning (i) the ownership of, or legal or equitable title
to, any  property,  (ii) whether the property  described  and referred to in the
Transaction  Documents  is  personal  property  or real  property or whether any
severance or other  provision in the  Transaction  Documents  purporting to make
certain property  personal  property is effective,  or (iii) the priority of the
interest of any person in any property or interest in property.

                (2) Each and all of the operative provisions of the Transactions

                                                August 18, 1986

To Each Person Listed on The Attached Schedule

                   SALE AND LEASEBACK OF AN UNDIVIDED INTEREST
                 IN PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES


Dear Sirs:

                We have acted as Special FERC counsel for Public Service Company
of  New  Mexico,  a  New  Mexico   corporation  (PNM)  in  connection  with  the
transactions contemplated by the Participation Agreement, dated as of August 12,
1986 (the Participation  Agreement),  among Burnham Leasing  Corporation,  a New
York corporation (the Owner  Participant),  The First National Bank of Boston, a
national  banking  association,  individually  and as  Owner  Trustee,  First PV
Funding Corporation,  a Delaware corporation,  Chemical Bank, a New York banking
corporation, as Indenture Trustee and PNM. All capitalized terms used herein and
not  otherwise  defined  shall have the  meanings set forth in Appendix A to the
Participation  Agreement.  This opinion is being  delivered  pursuant to Section
11(a)(23) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,   of  all  corporate  records,
agreements and other instruments, certificates, opinions and correspondence with
public officials, certificates of officers and representatives of PNM, and other
documents as we have deemed necessary or advisable for the purposes of rendering
the opinions set forth herein.




6091.BURNHAM.1106.08:1


<PAGE>


                As to matters of fact  relevant to our  opinion,  we have relied
upon the  representations  of the  parties  as set  forth  in the  Participation
Agreement,  including the  supporting  documentation  related  thereto and PNM's
October 18, 1985 petition to the FERC for an order (1) disclaiming  jurisdiction
over its proposed  sale and  leaseback of a portion of its interest in Unit 1 of
the Palo Verde Nuclear Generating Station, (2) disclaiming jurisdiction over the
Equity  Investors and Lessors of such  interest,  and (3)  determining  that the
Owner  Participants  and Lessors would not become public utilities as defined in
Section  201(e) of the Federal  Power Act,  16 U.S.C.  824(e)  (1982)  solely by
reason of their  participation in the proposed sale and leaseback  arrangements.
We have also  relied  upon the  requested  FERC Order  Disclaiming  Jurisdiction
issued on December 5, 1985.

                Based on the foregoing, we are of the opinion that:

                           (a) So long as the Lease shall be in effect,  neither
                the Owner  Participant nor the Owner Trustee will be or become a
                "public  utility"  within the  meaning of Section  201(e) of the
                Federal Power Act, 16 U.S.C. 824(e) (1982),  solely by reason of
                its  participation  in  the  transactions  contemplated  by  the
                Participation Agreement; and

                           (b) PNM does not  require  authorization  pursuant to
                Section  203(a) of the Federal  Power Act, 16 U.S.C.  ss.824b(a)
                (1982),  to sell the interest  contemplated by the Participation
                Agreement  to  the  Trust  in  accordance  with  the  terms  and
                conditions set forth in the Participation Agreement.

                There are no court  cases on point with  respect to our  opinion
expressed  in  paragraph  (a).  However,  the  FERC  and  its  predecessor  have
consistently  found that it would be inconsistent with the intent of the Federal
Power Act for it to find that investors or trustees  participating  in financing
transactions similar to those contemplated by the Participation  Agreement would
be public  utilities  under  Section  201(e) of the Federal Power Act, 16 U.S.C.

824(e)  (1982)  solely by reason of such  participation,  a finding  in which we
concur.  The FERC previously made such a finding with respect to PNM's sale of a
part of its ownership  interest in Palo Verde Nuclear  Generating Station Unit 1
in its  December 5, 1985 order.  The most  recent FERC order  containing  such a
finding related to El Paso Electric  Company's proposed sale of all or a portion

To Each Person Listed on The Attached Schedule


                 SALE AND LEASEBACK 0F AN UNDIVIDED INTEREST IN
                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES

Dear Sirs:

                We have acted as special  Arizona  counsel for  Burnham  Leasing
Corporation,  a New York corporation (the Owner Participant,  in connection with
the transactions contemplated by the Participation Agreement, dated as of August
12, 1986 (the  Participation  Agreement),  among Public  Service  Company of New
Mexico,  a New Mexico  corporation  (PNM),  The First National Bank of Boston, a
national banking association (FNB), individually and as Owner Trustee (the Owner
Trustee), First PV Funding Corporation, a Delaware corporation, Chemical Bank, a
New York banking  corporation,  as Indenture  Trustee,  and PNM. All capitalized
terms used herein and not otherwise  defined  herein shall have the meanings set
forth in  Appendix  A to the  Participation  Agreement.  This  opinion  is being
delivered pursuant to Section 11(a) (24) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.




6091.BURNHAM.1106.08:1


<PAGE>


                Certain  facts  particularly  relevant  to  our  opinion  may be
summarized as follows. The proposed transaction contemplates the sale of part of
PNM's  undivided  10.2%  interest in Unit 2 and certain common  facilities  (the
Facilities) to the Owner Trustee for the Owner  Participant.  The Owner Trustee,
will lease the purchased  interest in the Facilities  back to PNM on a long-term
net lease basis.  The purchase of PNM's  interest in the Facilities by the Owner
Trustee  will be  financed  in part by a loan made by the Loan  Participant  and
evidenced by a  non-recourse  obligation  (the Initial Series Note) of the Owner
Trustee.

                The  Initial  Series  Note  will be  issued by FNB under a lease
indenture,  for which  Chemical Bank will serve as Indenture  Trustee.  Upon the
closing of the lease  indenture,  the  Initial  Series  Note will be pledged and
assigned to the Collateral  Trust  Trustee.  The Initial Series Note will not be
secured by the property  subject to the Lease, but instead will be secured by an
assignment of the rights of the Owner Trustee, as lessor, to receive rentals and
certain other payments under the Lease with PNM.

                First PV  Funding  Corporation,  as the Loan  Participant,  will
obtain  funds for the  purchase of the Initial  Series  Note by  borrowing  from
commercial  banks under a Term Loan Agreement and, in connection  therewith,  by
the sale of debt securities.

                Based on the sale and leaseback transaction as described in this
letter, and as qualified below, we are of the opinion that:

                           (i)  the transaction will not be a fraudulent 
                conveyance under Arizona law;

                           (ii) the Trust will not be subject to regulation as a
                public   service   corporation   by  the   Arizona   Corporation
                Commission, at least unless and until the Trust actually assumes
                possession of the Facilities;

                           (iii) the Conveyance Documents, as identified below,
                are sufficient under Arizona law to convey such title as PNM has
                in the Facilities; and



                                                        -2-

                           (iv)  Arizona law does not  prohibit  FNB or Chemical
                Bank from serving,  respectively,  as Owner Trustee or Indenture
                Trustee and does not require  either  bank,  based solely on its
                involvement in the Palo Verde sale and leaseback,  to qualify to
                do business in Arizona.

                These conclusions are based on our understanding of the sale and
leaseback  transaction  as stated in this letter and our analysis of authorities
deemed by us to be analogous or otherwise relevant and briefly described in part
below.

                1.      Fraudulent Conveyance.

         We  understand  that:  (i) before the  closing of the  transaction,  an
independent  appraisal will confirm that the aggregate purchase price to be paid
for the Facilities is a reasonable estimate of their fair market value, and (ii)
the proposed sale and leaseback as described in the  Transaction  Documents will
be  approved  pursuant  to a  Final  Order  of the  New  Mexico  Public  Utility
Commission (the "Final Order") and (ii;) such  transactions  will not render PNM
insolvent or otherwise impair its financial condition.

                Our  review of Arizona  statutes  and case law has  revealed  no
authorities  that  directly  address a sale and  leaseback  and suggest that the
proposed  transaction  would be prohibited or fraudulent.  Moreover,  we believe
that the transfer of PNM's interest in PVNGS as contemplated  would be for "fair
consideration"  within the meaning of Arizona's  Fraudulent  Conveyance  Act and
therefore  would not be  fraudulent  under  Ariz.  Rev.  Stat.  Section  44-1004
(conveyance  without fair consideration  rendering  transferor  insolvent) ; id.
Section 44-1005  (conveyance  without fair  consideration  leaving transferor in
business with unreasonably  small capital);  or id. Section 44-1006  (conveyance
without fair consideration by transferor about to incur debts).

                Arizona case law indicates that even if a conveyance is for fair
consideration, it may be found fraudulent under Ariz. Rev. Stat. Section 44-1007
if made with actual intent -- as distinguished from an intent presumed at law --
to hinder, delay or defraud creditors.  Wallin v. Scottsdale Plumbing Co., Inc.,

Ariz.  App.  591,  557 .P.2d 190  (i976).  We note  that the  proposed  sale and
leaseback will have been reviewed and approved in at least two public regulatory
hearings.  Based on our review of Arizona law and the facts as described, we see
no basis for a successful  claim that the transaction  involves an actual intent
to defraud PNM's creditors.

                Arizona also has a venerable statute that predates statehood and
adoption of the Fraudulent Conveyance Act and provides that:

                A sale made by a vendor of goods and chattels in his  possession
or under his control, or an assignment of goods and chattels, unless the sale or
assignment is accompanied by an immediate delivery and followed by an actual and
continued  change of  possession  of things  sold or  assigned,  is prima  facie
evidence of fraud  against  creditors of the vendor,  or creditors of the person
making the assignment,  or subsequent purchasers in good faith. Ariz. Rev. Stat.
Section 44-1061.A.

                Our  research  has  not  revealed  any  reported  Arizona  court
decision  in the last fifty years that  relies  upon this  statute.  The few old
cases applying the statute make clear that failure of immediate  delivery is not
conclusive that a sale was fraudulent.  Instead, the statute is held to create a
presumption  of fraud that may be overcome by proof that a transfer  was made in
good faith and for fair consideration. Nolte v. Winstanley, 16 Ariz. 327, 145 P.
246 (1914);  Liebes V.  Steffy,  4 Ariz.  11, 32 P. 261  (1893).  If the statute
applies to the  proposed-sale  and leaseback,  it would seem  relatively easy to
rebut the presumption of fraud under the circumstances.

                Moreover,  we believe that there are  plausible  arguments  that
Ariz.  Rev. Stat. ss.  44-1061.A does not apply to the sale of PNM's interest in
the  Facilities.  Although  Arizona cases provide little  guidance on the issue,
such an interest  arguably is not "goods and chattels" within the meaning of the
statute.  We note in this regard that, even if the interest being transferred is
characterized  as  involving  in part  "personal  property,"  Arizona by statute
defines  personal  property to include  interests other than goods and chattels.
Ariz. Rev. Stat. ss. 1-215.25. Thus, even if PNM's interest in PVNGS is not real
property, such interest would not necessarily constitute "goods and chattels."

                The  few  reported  Arizona  cases  applying  Ariz.  Rev.  Stat.
ss.44-1061.A  also do not foreclose an argument that  "delivery" will in fact be
made under the  circumstances  of the  transaction.  We note in this regard that
ownership  of  PVNGS is  governed  by the ANPP  Participation  Agreement,  which
provides that Arizona Public  Service  Company is authorized to act as agent for
the owners of PVNGS,  and has  responsibility  and  control  over  construction,
operation, and maintenance of PVNGS.

                Gant  v.  Broadway,  2  Ariz.  315,  15  P.  862  (1887),  which
considered a predecessor statute to Ariz. Rev, Stat. ss. 44-1061.A,  states that
the acts  which  constitute  delivery  will  depend  upon the  character  of the
property sold and the circumstances of each particular case. More  specifically,
Gant  approved a jury  instruction  indicating  that where  property  remains in
possession of a third party,  "delivery"  can in some  circumstances  take place
when the  vendor,  purchaser,  and third  party  agree  that the goods  shall be
subsequently  held for the purchaser.  Whether Gant would guide an Arizona court
in applying  Ariz.  Rev.  Stat.  ss.44-1061.A  is  unclear,  because the statute
considered in that case differs  textually from the current statute,  i.e. ~ the
earlier statute provided for a conclusive presumption of fraud and did not refer
to assignment, and later cases apparently have not discussed Gant.

                Based on Gant,  one could  argued that any  required  "delivery"
will occur with  respect to the  transfer  of PNM's  undivided  interest  in the
Facilities because of the unusual nature of the property  transferred,  the fact
that the  transaction  will have been  subjected to prior review and approval in
public  regulatory  hearings,  and the  seemingly  indisputable  point  that the
transaction simply does not involve the sort of surreptitious  transfer that the
statute  intends to reach.  Whether Arizona courts would be receptive to such an
argument is difficult to predict, given the paucity of cases applying Ariz. Rev.
Stat. Section 44-1061.A.

                2.      Arizona Utility Regulation.

                Based  on our  review  of  the  Participation  Agreement,  other
Transaction Documents,  and the ANPP Participation  Agreement, as amended, we do
not believe that the Trust will become subject to Arizona utility

                Section  40-284.A of the Ariz.  Rev.  Stat.  prohibits a foreign
corporation  from  transacting  "public  service  business"  in  Arizona  unless
authorized to do so. Moreover, Ariz. Rev. Stat. ss. 40-284.B prohibits a

        "license,  permit or  franchise to own,  control,  operate or manage any
        public service business [from being) granted or transferred, directly or
        indirectly,  to any foreign corporation not lawfully  transacting within
        this state a public service business of like character."

Violation  of the  provisions  regulating a foreign  corporation  with regard to
transacting  a  public  service  business  can  result  in  criminal  and  civil
liability.

                Arizona law indicates that the provisions of Ariz.  Rev. Stat. ~
40-284  will  not  apply  to the  Trust as a  result  of the  proposed  sale and
leaseback because PNM is not a public service  corporation,  nor is it currently
transacting  "public service  business" within Arizona (for which conclusions we
rely on the  opinion  of Snell & Wilmer of even  date)  and the Trust  will not,
during the term of the Facility Lease, transact such business in this state.

                The Arizona  Constitution defines public service corporations to
include corporations  "furnishing  electricity for light, fuel or power" without
expressly  indicating  whether the electricity must be provided to the public in
Arizona.  The  constitutional   provision  empowering  the  Arizona  Corporation
Commission to regulate rates and charges of public service  corporations extends
that power only to services rendered to the public in Arizona.  Arizona statutes
and case law conform to this limitation.

6091.BURNHAM.1106.08:1


<PAGE>


                Because PNM is not now operating as a public service corporation
in Arizona in connection with its interest in PVNGS under the ANPP Participation
Agreement and in any event will retain control,  at least until default or other
termination of the Facility Lease, of its Arizona business,  we believe that the
proposed sale and leaseback will not violate Ariz.  Rev. Stat.  Section  40-284.
Moreover,  because the Trust will not furnish electricity for sale to the public
in Arizona  during the term of the  Facility  Lease,  we believe  that the Owner
Trustee and the Owner  Participant  will not be subject to  regulation as public
service corporations by the Arizona Corporation Commission. If the Owner Trustee
did take possession, depending upon the manner and then current structure of the
ANPP Participation  Agreement, it is possible that the Trust could then become a
public service corporation subject to regulation by the Corporation Commission.

                3.      Sufficiency of the Documents to Convey Title.

                Subject  to  the  assumptions,   exceptions  and  qualifications
expressed below, we are of the opinion that the Deed, the Deed and Bill of Sale,
and the Deed and Assignment of Beneficial Interest (all of the above instruments
being  collectively  referred to herein as the  "Conveyance  Documents") of even
date herewith  executed in connection with the transaction,  each of which names
PNM as  grantor  and FNB in its  capacity  as  Owner  Trustee  as  grantee,  are
sufficient under Arizona law to convey to FNB as Owner Trustee all of the right,
title and interest of PNM in and to the real and personal property  constituting
the Facilities and as identified in the Conveyance Documents.

                Our opinion is subject to the following assumptions,  exceptions
and  qualifications.  We assume that each of the Conveyance  Documents has been:
duly  authorized  and  executed  by  appropriate  action of each of the  parties
thereto;  duly delivered by PNM; and filed or recorded in the appropriate public
records.  We express no opinion as to the condition of title or  concerning  the
nature or existence  of the  interest of PNM in the real and  personal  property
constituting  the Facilities and as identified in the Conveyance  Documents.  We
note that the  Conveyance  Documents do not convey any portion of PNM's interest
in certain common facilities of PVNGS, certain ANPP Project Agreements,  and the

Unit 2 Retained  Assets,  and  certain  warranties  related  to the  Facilities.
Finally,  we are assuming that an appropriate  amendment of the trust disclosure
affidavit  relating to Title USA Trust No. 530 will be recorded under Ariz. Rev.
Stat.  ss. 33-401 with respect to the transfer  under the Deed and Assignment of
Beneficial Interest.

                4. Activities of the Owner Trustee and the Indenture Trustee.

                Our research  has  revealed no Arizona  statute or case law that
would prohibit FNB or Chemical Bank from serving, respectively, as Owner Trustee
or Indenture Trustee in the proposed transaction merely because of its status as
an  out-of-state  bank.  Moreover,  we do not  believe  that either bank will be
required,  solely  as  result  of its  participation  in the sale and  leaseback
transaction, to qualify to do business in Arizona.

                Our conclusion in this regard is qualified as follows. First, we
understand  that the Trust for which FNB will serve as trustee and the indenture
trust for which  Chemical Bank will serve as trustee will be formed  exclusively
for the purpose of the lease  financing of the Palo Verde  transaction.  Second,
the Owner Participant has informed us and we assume,  that the Owner Participant
has no interest in property located in Arizona except its beneficial interest as
Owner Participant in the assets held by the Trust and that the Owner Participant
engages  in no  business  or other  activities  within  this  state,  except the
activities contemplated by the Participation Agreement.  Third, FNB and Chemical
Bank  have  participated  previously  in four  sale and  leaseback  transactions
substantially  similar to that contemplated by the  Participation  Agreement and
may participate in a limited number of substantially similar transactions in the
future with respect to interests in PVNGS.  Fourth,  we do not offer any opinion
whether  activities  of Chemical  Bank or FNB within this state not described in
this letter  would  require  either bank to qualify to do business in this state
when considered  along with  participation in the Palo Verde sale and leaseback.
Finally, we do not offer any opinion whether qualification would be necessary if
the Owner Participant or either bank, in its capacity as trustee, assumed actual
possession of any portion of PVNGS upon default by PNM or upon other termination
of the  Facility  proposed  sale and  leaseback  and the  property is located in
Arizona.

                Apart from the case law described  above,  Ariz.  Rev. Stat. ss.
l0-106.B  provides that,  "(without  excluding  other  activities  which may not
constitute transacting business in this state, foreign corporations shall not be
considered to be transacting business by reason of carrying on in this state any
one or more of the  following  activities."  The  specified  activities  include
"(creating  as a borrower or lender,  or acquiring,  indebtedness,  mortgages or
other security interests in real or personal property, "id. ss. 44-106.B.7,  and
"[s]ecuring or collecting debts or enforcing any rights in property securing the
same," Id. ss. 44-106.B.8.

                Our research has revealed no reported  Arizona  cases that apply
the statutory  provisions  described in the preceding paragraph in circumstances
that are directly on point with respect to the proposed sale and  leaseback.  At
the same time,  we note that  Arizona  case law does pot suggest  the  statutory
provisions will be applied other than in accord with their plain language.  That
language,  we believe,  indicates that certain  actions by FNB and Chemical Bank
will not constitute transacting business within Arizona.

         The  statutory  provisions  indicate  that FNB will not be  transacting
business  in the state by virtue of its  issuance  of the  Initial  Series  Note
secured by assignment of the lease payments because this action,  even if deemed
to be carried on in Arizona, involves the creation as a borrower of indebtedness
or other security interests in real or personal property. We note in this regard
that Arizona case law indicates  that the right to future  payments under a real
property lease is an incorporeal  hereditament  that constitutes and interest in
land.  Valley National Bank v. Avco  Development Co., 14 Ariz. App. 56, 480 P.2d
671 (1971).

                The statutory  provisions  also suggest that  Chemical  Bank, as
Collateral  Trust Trustee,  will not be transacting  business  within Arizona by
virtue of its  acceptance  of the  Initial  Series  Note or its  receipt  of the
assigned rental payments because these actions constitute securing or collecting
debts or enforcing any rights in property securing the same.

Assets,  and  certain  warranties  related to the  Facilities.  Finally,  we are
assuming  that  an  appropriate  amendment  of the  trust  disclosure  affidavit
relating to Title USA Trust No. 530 will be recorded  under Ariz.  Rev.  Stat. ~
33-401 with respect to the transfer  under the Deed and Assignment of Beneficial
Interest.

                The  opinion  stated in this  letter is  limited  to  matters of
Arizona  law and  federal  laws of general  applicability  as they exist on this

                This  opinion is being  delivered  to you solely for your use in

                  PALO VERDE NUCLEAR GENERATING STATION UNIT 2
                          AND CERTAIN COMMON FACILITIES
Dear Sirs:

                We have acted as special New Mexico counsel for Burnham  Leasing
Corporation, a New York corporation (the Owner Participant),  in connection with
the transactions contemplated by the Participation Agreement, dated as of August
12, 1986, (the Participation Agreement),  among the Owner Participant, The First
National Bank of Boston,  a national  banking  association,  individually and as
Owner Trustee,  First PV Funding Corporation,  a Delaware corporation,  Chemical
Bank, a New York banking  corporation,  as Indenture  Trustee and Public Service
Company of New Mexico, a New Mexico  corporation  (PNM).  All capitalized  terms
used herein and not otherwise  defined  herein shall have the meanings set forth
in Appendix A to the  Participation  Agreement.  This opinion is being delivered
pursuant to Section 11(a)(25) of the Participation Agreement.

                As such counsel we have examined originals or copies,  certified
or  otherwise  identified  to  our  satisfaction,  of  such  corporate  records,
agreements and other instruments, certificates, orders, opinions, correspondence
with public officials,  certificates of officers and representatives of PNM, and
other  documents,  as we have deemed  necessary or advisable for the purposes of
rendering the opinions set forth herein.

                Based on the  foregoing,  we are of the opinion  that :under New
Mexico Applicable Law now in effect:


6091.BURNHAM.1106.08:l


<PAGE>


                (1) Each Transaction Document to which PNM is a party,  assuming
        the due  authorization,  execution  and  delivery  thereof by each party
        thereto,  constitutes  the legal,  valid and binding  obligation of PNM,
        enforceable against PNM in accordance with its terms

                (2) Neither the execution, delivery or performance by PNM of any
        Transaction Document to which it is a party, nor the consummation by PNM
        of the transactions contemplated thereby, nor the compliance by PNM with
        the  provision  thereof,  conflicts  with or  results in a breach of any
        Applicable  Law of any  state,  county,  municipal,  regional  or  other
        governmental authority, agency, board, body, instrumentality or court of
        New Mexico ("New Mexico Governmental Authority").

                (3)  No   Governmental   Action  of  or  with  any  New   Mexico
        Governmental  Authority is required in  connection  with the  execution,
        delivery or  performance  by PNM of, or the  consummation  by PNM of the
        transaction  contemplated by, any Transaction Document to which PNM is a
        party,  except the New Mexico  Order,  which has been duly issued by the
        NMPSC, and such other New Mexico  Governmental  Actions (i) as have been
        duly obtained, given or accomplished,  and (ii) as may be required to be
        obtained,  given or accomplished from time to time after the date hereof
        in connection with the maintenance, use, possession or operation of Unit
        2 or otherwise  with respect to Unit 2 and PNM's  involvement  therewith
        and which are, for PVNGS,  routine in nature and which we have no reason
        to believe will not be timely obtained.

                (4)  Assuming  that  all  filings  required  to be made in other
        jurisdictions  have  been  duly  made,  upon  (a) the  filing  of  UCC-l
        financing  statements in appropriate  form relating to the Indenture and
        the Collateral Trust Indenture with the Secretary of State of New Mexico
        and the County Clerk of Bernalillo  County, New Mexico and the filing of
        the Indenture and the Collateral  Trust  Indenture with the Secretary of
        State of New Mexico  pursuant to the New Mexico Public  Utility Act, (b)
        the delivery of the  Original of the  Facility  Lease to, and so long as
        the same is retained by, the Indenture Trustee,  and (c) the delivery of
        the Pledge Lessor Notes (as defined in the Collateral  Trust  Indenture)
        


                                       -2-

        to,  and so long as the same  are  retained  by,  the  Collateral  Trust
        Trustee,  the  Indenture  Trustee  will have a  perfected  UCC  security
        interest in the Lease  Indenture  Estate  pursuant to, and to the extent
        provided in, the Indenture, and the Collateral Trust Trustee will have a
        perfected UCC security  interest in the Pledged  Property (as defined in
        the Collateral Trust Indenture), pursuant to, and to the extent provided
        in, the Collateral  Trust  Indenture,  and no filing or recording of any
        document  (except those  enumerated above and the filing of continuation
        statements  in  appropriate  form with  respect  to the UCC-l  financing
        statements  referred  to above at the  time and in the  matter  provided
        under the laws of New Mexico) will be necessary or appropriate under the
        laws of New Mexico to  establish,  preserve,  protect  and  perfect  the
        security interests referred to above.

                 (5) So long as the Facility Lease is in effect, and in reliance
        upon  the New  Mexico  Order,  neither  the  Owner  Trustee,  the  Owner
        Participant,  nor the Indenture  Trustee,  will, by reason either of its
        entering  into  any  Transaction  Document  or  its  performance  of any
        transaction  contemplated  thereby,  be  subject  to  regulation  as  an
        "electric  utility," a "public  utility," or a "public  utility  holding
        company" by the NMPSC or any other New Mexico Governmental Authority.

                (6)  Neither  the Owner  Trustee  nor the  Indenture  Trustee is
        required  to qualify to do  business  in New Mexico in order to serve in
        such capacity.

                (7) No New Mexico Tax will be imposed  upon  payments of Rent by
        PNM to the Owner Trustee under the Facility Lease or in connection  with
        the transfer of the Undivided  Interest or the Real Property Interest by
        PNM to the Owner Trustee.

                The opinions  expressed  herein are subject in each> case (a) as
to enforceability,  to bankruptcy,  insolvency,  reorganization,  moratorium and
other  similar laws  heretofore  or hereafter  enacted  affecting  creditors' or
lessors' rights generally, general principles of equity, and the availability of
specific performance and other equitable remedies, (b) to the qualification that


                                       -3-
6091.BURNHAM.1106.08:l


<PAGE>

any provision in the  Transaction  Documents which purports to permit any Person
to make  determinations,  take actions or require  payments under  indemnity and
similar  provisions may be subject to requirements  that such  determinations be
made, such actions be taken and such payments required on a reasonable basis and
in good  faith,  (c) to  possible  limitations  upon  the  exercise  of  certain
indemnity,  remedial  or  procedural  provisions  contained  in the  Transaction
Documents, which limitations do not in our opinion make such indemnity, remedial
or  procedural  provisions,  taken  as a  whole,  inadequate  for the  practical
realization of the benefits provided by the Transaction Documents, (d) as to the
perfection of UCC security interests in proceeds, to the qualification that such
perfection  is limited to the degree set forth in Section  9-306 of the UCC, and
(e)  as  to  the  perfection  of  UCC  security   interests  in  money,  to  the
qualification  that such perfection is limited to money in the possession of the
secured party.

                For  purposes  of this  opinion we have  assumed  that the Owner
Participant and the Lessor will exercise their rights, and that PNM will perform
its  obligations,  under  Section  13(c) of the  Facility  Lease  if it  becomes
necessary to do so to remain in compliance  with the New Mexico  Order.  We have
further  assumed  that no Lease  Transaction  (as  that  term is used in the New
Mexico Order) entered into by PNM subsequent to the date hereof will result in a
violation of the New Mexico Order.

                We do not purport to be experts in the laws of any jurisdictions
other than New  Mexico and the United  States.  The  opinions  expressed  herein
relate only to the existing  laws of New Mexico,  and we express no opinion with
respect  to the laws of the  United  States or any  jurisdiction  other than New
Mexico.  Our  opinions  do not cover any  matter  relating  to the "blue sky" or
securities laws of New Mexico or any other jurisdiction.


                                    Yours very truly,

                                    RODEY, DICKASON, SLOAN, AKIN & ROBS, P.A.

        constitute  a  "Deemed  Loss  Event"  if such  change  shall  include  a
        provision  drafted  in a manner  reasonably  satisfactory  to the  Owner
        Participant  which exempts 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  counsel to the Owner Participant)
        a court  could  reasonably  hold  that the  statute  incorporating  such
        provision is unconstitutional;

        affect its or its  Affiliates'  business,  and (V) the Lessee shall have

        indemnified" (as each such term is defined in the Price-Anderson Act) is

        Lease Term, to any increased real or potential liability in respect of a
        Nuclear  Incident,  (ii) the aggregate  liability  for a single  Nuclear
        Incident  of  "persons  indemnified"  (as such  term is  defined  in the
        Price-Anderson   Act)  exceeds  the  amount  of   financial   protection
        established by the NRC as a condition to the License,  unless the change
        is such that neither the Owner Trustee nor

        the Owner Participant may be exposed, either during or subsequent to the
        Lease Term, to any increased real or potential liability in respect of a
        Nuclear  Incident,  (iii) the amount of financial  protection  required,
        including  but not limited to the  limitation  on the amount of deferred
        premiums for such financial protection, is increased,  unless the change
        is such that neither the Owner Trustee nor the Owner  Participant may be
        exposed, either during or subsequent to the Lease Term, to any increased
        real or potential  liability in respect of a Nuclear  Incident,  or (iv)
        either the Owner Trustee or the Owner  Participant may be exposed to any
        other  increase  in its real or  potential  liability  in  respect  of a
        Nuclear  Incident,  either  during or  subsequent  to the Lease Term, it

        existence of insurance,  retrospective premiums, indemnities (whether by
        the Lessee or any other  person) or other forms of financial  protection
        (similar or dissimilar to the  foregoing)  shall not be deemed to reduce
        or eliminate any exposure of the Owner Trustee or the Owner  Participant
        to real or potential  liability in respect of a Nuclear  Incident except
        to the extent (x) such  financial  protection  is provided by the United
        States Government under Congressional  action which does not require any
        further appropriation or other act of Congress or any other Governmental
        Authority,  (y) the terms of such  financial  protection  are  otherwise
        satisfactory to the Owner Trustee and the Owner Participant, and (z) the
        Owner Trustee or Owner Participant 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; provided, however,
        that such  change  shall not  constitute  a "Deemed  Loss Event" if such
        change  shall  include  a  provision  drafted  in  a  manner  reasonably
        satisfactory  to the Owner  Participant  which exempts 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 counsel to
        the Owner  Participant) a court could  reasonably  hold that the statute
        incorporating such provision is unconstitutional;

        become  liable  in  any  capacity,  in  respect  of any  portion  of the

        or obligation imposed as of the date hereof on licensees of the NRC;

                 (4) Illegality.  If there shall be any change in Applicable Law
        or  any  Governmental  Action  the  effect  of  which  is  to  make  the
        transactions  contemplated  by the Transaction  Documents  unauthorized,
        illegal or otherwise contrary to Applicable Law;

                (5)  Limitation  on  Exercise  of Rights.  Any change in, or new
        interpretation  by Governmental  Authority  having  jurisdiction of, the
        License  and the  License  Amendment  (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 Transact ion Document  would
        constitute impermissible control over Unit 2 or the licensees of Unit 2,
        other than an assertion that affects such rights in a manner  consistent
        with the second sentence of Section 184 of the Atomic Energy Act and the
        NRC's regulations  thereunder  (including,  without  limitation,  10 CFR
        Section 50.81, as now and hereafter in effect);

                (6) Early  Licensee  Status.  If as a result of any  expiration,
        revocation,  suspension, amendment or interpretation by any Governmental
        Authority   of  the  License,   the  License   Amendment  or  any  other
        Governmental  Action or  change  in  Applicable  Law,  either  the Owner
        Trustee or the Owner  Participant shall be required to become a licensee
        of the NRC prior to the Lease Termination Date;

                (7)  Suspension or  Termination  of Insurance.  If any policy of
        liability  insurance  with  respect  to Unit 2  shall  be  suspended  or
        terminated,   or  the  coverage  thereunder  reduced,   for  any  reason
        whatsoever  or shall be amended  or  supplemented,  in either  case in a

        insurance  shall  not be  immediately  replaced  by  insurance  or other
        financial  protection  satisfactory to the Owner  Participant  effective
        immediately upon such suspension,  termination,  reduction, amendment or
        supplementation   which,   in  the  reasonable   opinion  of  the  Owner
        Participant,  is at least as protective of it (in all respects deemed by
        it to be material) as the policy of insurance so terminated,  suspended,
        reduced,  amended or supplemented,  unless the aggregate liability for a
        Nuclear  Incident of "persons  indemnified"  (as such 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, reduced,
        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

                  (16)  Regulation.  So long as the Facility Lease is in effect,
        assuming  the  proper  filing  of Form U-7D with the SEC on or within 30
        days after the Closing Date, under Applicable Law now in effect, neither
        the Loan Participant,  the Owner Participant,  FNB nor the owner Trustee
        will be or  become,  solely by reason of either its  entering  into this
        Participation  Agreement or any other Transaction  Document to which any
        of them is, or is to become, a party, or the  transactions  contemplated
        hereby or thereby,  subject to regulation (i) as an "electric  utility",
        an "electric  utility company",  a "public  utility",  a "public utility
        company", a "holding company",  or a "public utility holding company" by
        any Federal,  state (other than, as to the Owner Participant,  New York,
        as to which no  representation  or  warranty  is given) or local  public
        utility  commission  or  other  regulatory  body,   authority  or  group
        (including,  without  limitation,  the SEC,  the FERO,  the NMPSC or the
        Arizona  Corporation  Commission)  or (ii) in any manner by the NRC. The
        Lessee  is  not,  and  covenants  that  (except  in  connection  with  a
        transaction  permitted  by  Section  10(b) (3) (ii)  hereof) it will not
        become,  a "holding  company"  or a  "subsidiary  company" of a "holding
        company" or an "affiliate" of a "holding  company" within the meaning of
        the Holding  Company Act. The Lessee is not subject to regulation by the
        Arizona  Corporation  Commission as a public utility or a public service
        corporation.

                  (17)  Authorizations6 etc. The Lessee has not failed to obtain
        any  Governmental  Action  or other  authorization,  license,  approval,
        permit, consent, right or interest, where a failure to obtain such would
        materially  and  adversely  affect the ability of the Lessee to carry on
        its business as presently  conducted or as described in the Registration
        Statement

                  (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 other 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  ANPP  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 ANPP 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 Transportation 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
        become,  an  "investment  company",  or a  company  "controlled"  by  an
        "investment company", within the meaning of the Investment Company Act

                  (b)   Agreements of Lessee

                  (1)  Delivery  of  Documents.  The Lessee  agrees that it will
        deliver to the Owner  Participant and the Loan Participant  (and, in the
        case of Sections 10(b) (1) (iii) and (v) hereof, the Owner Trustee):

                  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
                  under this Section 13(b));

        Indemnitee realizes a net permanent tax benefit by reason of the payment
        of any indemnity  under Section  13(b),  such  Indemnitee  shall pay the
        Lessee,  but  not  before  the  Lessee  shall  have  made  all  payments
        theretofore due to such Indemnitee

        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  thereto-fore  made  pursuant to this Section  13(b) less the
        aggregate  amount of all prior payments by 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

        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 (V) 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  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

        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  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) (6) 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

        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 C4), 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  (in6luding,  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 the Lessee does not request
        that a Tax be contested pursuant to this paragraph (5), the Lessee shall

        indemnification  under  Section  13(b) (1) 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  maybe,  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  satisfactory  to the  Owner  Trustee  and such
        Indemnitee  within a  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  Indermitee  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 the  Lessee  under this  Section  13(b) and it shall be
        necessary, in 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 tern  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

                  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

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 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 New 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



                                      -87-

<PAGE>

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
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

        plus  accrued but unpaid  interest  thereon to the date of  distribution
        bears to the aggregate unpaid  principal  amount of all Notes,  together

        proportion that the amount of such indemnitflor  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;

        Lessee  is  not,  and  covenants  that  (except  in  connection  with  a
        transaction  permitted  by  Section  10(b) (3) (ii)  hereof) it will not
        become, a It "holding  company" or a "subsidiary  company" of a "holding
        company" or an "affiliate" of a "holding  company" within the meaning of
        the Holding  Company Act. The Lessee is not subject to regulation by the
        Arizona  Corporation  Commission as a public utility or a public service
        corporation.

                (17)  Authorizations,  etc.  The Lessee has not failed to obtain
        any  Governmental  Action  or other  authorization,  license,  approval,
        permit, consent, right or interest, where a failure to obtain such would
        materially  and  adversely  affect the ability of the Lessee to carry on
        its business as presently  conducted or as described in the Registration
        Statement.

                  (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 other 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  ANPP  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 ANPP 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 2 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 2. The description of Unit 2 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 become,
        an "investment  company",  or a company  "controlled"  by an "investment
        company", within the meaning of the Investment Company Act

             (b)      Agreements of Lessee.

            (1) Delivery of Documents. The Lessee agrees that it will deliver to
        the Owner Participant and the Loan Participant (and, in the case of
        Sections 10(b) (1) (iii) and (v) hereof, the Owner Trustee):

                has reviewed,  or caused to be reviewed by individuals under his

                Transaction  Document and each  Financing  Document to which the
                Lessee is a party and has made,  or caused to be made  under his
                supervision,  a review of the transactions  contemplated  hereby
                and  thereby  and  the  condition  of  the  Lessee  during  such

        the  Owner  Participant  or  the  Loan Participant.

        Agreement on or after the Closing Date. The Lessee will not,  unless the
        Owner Participant otherwise consents, accept or approve any amendment to

        the ANPP Participation Agreement. The Lessee shall (A) provide copies of
        any proposed  amendment  to or  modification  of the ANPP  Participation
        Agreement  to the Owner  Participant  not less than 45 days prior to the

        thereof 45 days prior to such execution,  in which case the Lessee shall
        provide  notice thereof as promptly as possible after becoming so aware)
        and (B) upon such execution  furnish to the Owner  Participant a copy of
        any such  amendment or  modification  as executed.  The Lessee will not,
        except as  permitted by paragraph  (ii) above or by the  Assignment  and

            (ix) Notes and Bonds.  The Lessee will not,  and will not permit any
        of its  Affiliates to, acquire any of the Notes or, except in connection
        with the selection of Bonds for  redemption  pursuant to the  Collateral

        31,  1990,  impose upon the Lessee the  obligation  to create,  fund and
        maintain an external  reserve fund  dedicated to paying all the costs of

        the Lessee  will  create  and  maintain  the  Decommissioning  Fund;  if
        Applicable Law or Governmental  Action shall thereafter  impose upon the
        Lessee an  obligation  to create and maintain  such a fund,  any fund in
        compliance  with  Applicable  Law or such  Governmental  Action shall be
        deemed  satisfactory  to  the  Owner  Participant  for  purposes  of the
        preceding sentence;  provided,  however, the Lessee shall in any and all
        events  maintain and fund such an external  reserve in  accordance  with
        prudent utility practice and thereafter review such fund, at least every
        five years after its creation,  and modify the same as to amount or rate
        of  accumulation  to bring the same, it necessary,  into conformity with
        prudent utility  practice.  (B) Except to the extent provided in clauses
        (C) and (D) below, as between the Lessee,  the Owner Trustee,  the Owner
        Participant  and any transferee  (including by way of lease) or assignee
        of any of the  Lessor's  or the  Owner  Participant's  right,  title  or
        interest in Unit 2, the Lessee agrees to pay, be solely responsible for,

        Facility Lease shall have expired upon expiration (or early  termination
        pursuant  to  Section  14(e) of the  Facility  Lease) of the Lease  Term
        (other than in  connection  with an Event of Loss,  Deemed Loss Event or

        and sell power and energy from its Generation  Entitlement Share through

        back to such  Lease  Termination  Date at a rate per annum  equal to the
        Prime Rate) equal to 20% of Facility  Cost, or (y) in the case or clause
        (2) above, net electric  revenues in an aggregate amount  (discounted as
        aforesaid)  equal to 20% of Facility Cost,  the Lessor shall  thereafter
        reimburse the Lessee in respect of the decommissioning obligation of the
        Lessee  hereunder  in an amount  equal to any further  rent  received or

        such rent or proceeds are attributable to the decommissioning obligation
        of the Lessee  under  this  Section  10(b) (3) (xi) with  respect to the
        period from and after such Lease  Termination Date (payable on an annual
        basis with  respect to each year or portion  thereof  during the term of
        such  lease  referred  to in  clause  (1)  above or such  agency  period
        referred  to in clause (2)  above);  provided,  however,  that when such
        amount has been paid the Lessor shall be relieved of all  obligations to
        make further  reimbursement  to the Lessee for such purpose.  (0) In the
        event that (i) the Facility Lease shall have expired upon the expiration

        of the  Lease  Term  (other  than in  connection  with an Event of Loss,

        exercise by the Lessee of the purchase  option provided by Section 13(b)
        of the Facility  Lease),  and (iii) the net sales  proceeds  (discounted
        back to such  Lease  Termination  Date at a rate per annum  equal to the
        Prime Rate) received by the Lessor in connection  therewith shall exceed
        20% of Facility  Cost (reduced by the  percentage  of Facility  Cost, if
        any, actually realized by the Lessor pursuant to clause (C) above), then
        the Lessor shall reimburse the Lessee in respect of the  decommissioning
        obligation  of the  Lessee  hereunder  in an  amount  equal  to any  net
        proceeds of such sale to the extent that such proceeds are  attributable

        obligations  of the  Lessor  under  this  Section  10(b) (3) (xi)  shall
        terminate);  provided,  however,  that any such reimbursement  shall not
        reduce the amount of such net sales  proceeds  retained by the Lessor to
        an amount  (discounted as aforesaid)  equal to less than 20% of Facility
        Cost  (reduced by the  percentage  of Facility  Cost,  if any,  actually
        realized by the Lessor pursuant to clause (C) above).  The reimbursement
        obligations  of the Lessor  under  clauses (C) and (D) above are for the
        sole  benefit of the Lessee,  and no other Person shall be a third party
        beneficiary with respect  thereto.  In the event that the Lessee and the
        Lessor  shall not agree as to the amount of gross  rents,  net  electric
        revenues  or net  sales  proceeds  attributable  to the  decommissioning
        obligation of the Lessee under this Section 10(b) (3) (xi),  such amount
        shall  be  determined  by  the  Appraisal  Procedure.  For  purposes  of
        determining  Facility  Cost under  clauses  (C) and (D) of this  Section

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
which  would  constitute  the willful  misconduct  or gross  negligence  of such
Indemnitee (unless imputed to such Indemnitee by reason of Unit 2, the Undivided
Interest,  the Real  Property  Interest,  PVNGS,  the  PVNGS  Site or any  other
facilities at the PVNGS Site or any occurrence in connection  with any thereof),

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 the net amount  actually

      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 is consummated, except as provided in
      Section 13(b) (2), the Lessee shall pay, and shall  indemnify,  defend and
      hold each Indemnitee  harmless,  on an After-Tax Basis,  from and against,
      any and all Taxes howsoever imposed (whether imposed on or with respect to
      the  Indemnitee,  the Lessee,  Unit 2, the  Undivided  Interest,  the Real
      Property Interest,  any Capital  Improvement or the PVNGS Site or any part
      thereof or interest  therein or otherwise) by any Federal,  state or local
      government or subdivision thereof or taxing authority in the United States
      or by any  foreign  country or  subdivision  thereof or by any  foreign or
      international  taxing  authority in connection with or relating to (A) the

      imposition  of any Lien (or  incurrence  of any liability to refund or pay
      aver any amount as a result of any Lien  other  than  Owner  Participant's
      Liens and Owner Trustee's Liens) other than Owner  Participant's Liens and
      Owner  Trusteees  Liens  on,  Unit 2,  the  Undivided  Interest,  the Real

            (2) Exclusions from General Tax Indemnity. Section 13(b) (1) (except
      for the first sentence thereof) shall not apply to:

            (i) Taxes based on, or measured by, net income imposed by the United
        States federal government  (including,  without limitation,  any minimum
        Taxes,  capital gains Taxes,  any Taxes on, or measured by, items of tax
        preference,  surcharges,  additions  to tax,  penalties,  fines or other
        charges in respect thereof);

            (ii) Taxes (other than sales,  use or rental  Taxes)  imposed by any
        state  or local  government  or  subdivision  thereof  or  other  taxing
        authority in the United States or by any foreign  country or subdivision
        thereof or by any foreign or  international  taxing  authority  that are
        based on, or measured by, the net income,  items of tax preference,  net
        worth or capital of an Indemnitee, or other taxes imposed in lieu of any

        such Taxes,  except,  with respect to the Owner Trustee,  the Trust, the
        Trust Estate,  the Owner  Participant  and any Affiliate of any thereof,
        any such Taxes  imposed by a  jurisdiction  as a result of a relation or
        asserted relation of such jurisdiction to the transactions  contemplated
        by the Transaction  Documents or the Financing  Documents or as a result
        of the activities of the Lessee,  any ANPP  Participant or any Affiliate
        of any thereof in such jurisdiction;  provided, however, that the amount
        of any such excepted  Taxes shall be calculated (i) on a pro forma basis
        assuming that such Indemnitee has no other taxable income or loss in the
        taxing  jurisdiction  imposing the Tax (provided  that such  calculation
        shall take into account any allocation or  apportionment  method used by
        such  jurisdiction  except to the  extent  that such  method  takes into
        account the income or activities of business entities  organized outside
        the United States) and is able to use any net operating loss  carryovers
        (generated   solely  by  reason  of  and  solely   attributable  to  the
        transactions  contemplated by the Transaction Documents or the Financing
        Documents, and for this purpose a similar pro forma calculation shall be
        made) to the fullest extent,  reasonably  determined,  in good faith, by
        the Indemnitee,  and (ii) by taking into account any actual reduction in
        Taxes in such  jurisdiction  or in any other  jurisdiction in which such
        Indemnitee  is subject to tax (whether such  reduction  results from the
        operation  of  allocation  or  apportionment  formulas,  from credits or
        otherwise,  except  that  no  account  shall  be  taken  of  any  actual
        reductions  of  tax  benefits  described  in  the  Tax   Indemnification
        Agreement  or any tax  liability  generated by  transactions  other than
        those  contemplated  by  the  Transaction  Documents  or  the  Financing
        Documents) which reduction results from the transactions contemplated by
        the Transaction Documents or the Financing Documents;  provided further,

        however, that, with respect to any Tax based on, or measured by, capital
        or net worth,  the Lessee's  indemnity  obligation  shall not exceed the
        incremental  portion  of  such  Tax  attributable  to  the  transactions
        contemplated by the Transaction Documents;

            (iii)  Taxes  attributable  to the  Undivided  Interest  or the Real
        Property Interest to the extent that such Taxes are imposed with respect
        to any  period  after  (a) the Lease  Termination  Date and (b) the date
        possession of the Undivided  Interest and the Real Property Interest has
        been delivered to the Lessor as provided in Section 5(a) of the Facility
        Lease,  unless such Taxes relate to events  occurring or matters arising
        prior to or simultaneously with either of the aforementioned dates;

            (iv) Taxes on or with  respect  to an  Indemnitee  arising  from any
        voluntary  transfer by such  Indemnitee of any interest in the Undivided
        Interest,  the Real Property  Interest,  the Trust Estate, the Indenture
        Estate,  the  Notes or any other  right or  interest  arising  under the
        Transaction  Documents or the  Financing  Documents,  unless an Event of
        Default  has  occurred  and is  continuing,  or  Taxes  arising  from an
        involuntary  transfer by such  Indemnitee of any such  interest  arising
        from a bankruptcy or similar  proceeding in which such Indemnitee is the
        debtor unless such bankruptcy or other  proceeding was caused,  in whole
        or in part, by the Lessee or any Affiliate thereof;

            (v)  Taxes  based  on  or  measured  by  any  fee,   commission   or
        compensation  received by an  Indemnitee  for acting as trustee,  or for
        other  services  rendered,  in connection  with any of the  transactions
        contemplated by the Transaction Documents or the Financing Documents;

            (vi) Taxes on or with respect to an Indemnitee  arising by reason of
        such  Indemnitee's  failure to file proper and timely reports or returns
        (unless the filing of such reports or returns is the  obligation  of the
        Lessee under the Transaction  Documents or the Financing  Documents) and
        any penalties or additions to tax imposed by reason of such Indemnitee's
        failure  to  comply  with the  laws  imposing  such Tax or its  material
        failure to comply with its obligations  under Section 13 (b) (6), unless
        such  failure  results  from any  action of the Lessee or failure by the
        Lessee to comply with any provision of the Transaction  Documents or the
        Financing   Documents,   including  the  failure  to  provide  necessary
        information;

            (vii) Taxes on or with respect to an Indemnitee  arising as a result
        of a material failure of such Indemnitee to fulfill its obligations with
        respect to the contest of any claim in accordance with Section 13(b) (4)
        of this Participation Agreement;

            (viii)  Taxes  imposed  on  or  with  respect  to a  transferee  (or
        subsequent   transferee)  of  an  original   Indemnitee  (other  than  a
        transferee  or  subsequent  transferee  that  is  an  Affiliate  of  its
        transferor)  to the extent  that the amount of such  Taxes  exceeds  the
        amount of taxes that would have been  imposed on or with respect to such
        original  Indemnitee  but for the  transfer  to such  transferee  or, if
        imposed,  would not have been  subject  to  indemnification  under  this
        Section  13(b);  provided,  however,  that the  exception in this clause
        shall  not  apply to any  transferee  where  such  transfer  shall  have
        occurred during the continuance of an Event of Default;

            (ix) any  Taxes  imposed  on the  Lessor  or the  Owner  Participant
        resulting from, or which would not have occurred but for, Lessor's Liens
        or Owner  Participant's  Liens and any Taxes  imposed  on the  Indenture
        Trustee which would not have occurred but for Indenture Trustee's Liens;

            (x) any Tax that results solely from the activities of an Indemnitee
        in  any  taxing  jurisdiction  which  activities  are  unrelated  to the
        transactions  contemplated by the Transaction Documents or the Financing
        Documents;

            (xi) any Tax on or with respect to an Indemnitee  resulting from any
        amendment  or  modification  entered  into  by  such  Indemnitee  to any
        Transaction  Document or Financing Document if the Lessee is not a party
        to such amendment or modification or has not consented to such amendment
        or  modification,  in each case  unless an Event of  Default  shall have
        occurred and be continuing; and

            (xii) any Tax on or with respect to an Indemnitee 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 under this Section 13(b));

        provided, however, that the foregoing subclauses (i) through (xii) shall
        not apply to any Tax imposed on the Loan  Participant  or the  indenture
        estate under the Collateral Trust Indenture.

                  (3)  Calculation  of General Tax  Indemnity  Payments.  If any
        Indemnitee realizes a net permanent tax benefit by reason of the payment
        of any indemnity  under Section  13(b),  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 (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
        to this Section 13(b) less the aggregate amount of all prior payments by
        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,  (H) 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 2,
        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 a 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)(6)  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
        l3(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); provided, further,

        however,  that  notwithstanding  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  Indemnity  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 the Lessee  does not  request  that a Tax be  contested
        pursuant to this  paragraph  (5),  the Lessee  shall pay the  Indemnitee
        therefor unless such Tax was not included in the  indemnification  under
        Section 13(b) (1) 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  satisfactory  to the  Owner  Trustee  and such
        Indemnitee  within a  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 the  Lessee  under this  Section  13(b) and it shall be
        necessary, in 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.

            SECTION 14. Transaction Expenses.

            (a) Transaction Expenses. Subject to the provisions of paragraph (c)
below,  with funds provided by the Owner  Participant,  the Owner Trustee hereby
agrees that it will pay when due an appropriate portion (taking into account the
other  undivided  interests in Unit 2 sold on August 16, 1986) of the  following

        Subject to the provisions of paragraph (c) below,  funds for the payment
        of Transaction Expenses will be provided by the Owner Participant to the
        Owner Trustee and the Owner Trustee will promptly disburse such funds.

            (b)  Post-Closing  Expenses.  The Lessee will pay,  as  Supplemental
Rent, (i) the ongoing fees,  expenses,  disbursements and costs (including legal
and other  professional  fees and expenses) of or incurred by the Owner Trustee,

           SECTION 15. Owner Participant's Transfers.

            (a) Transfers.  After the Closing Date,  except as  contemplated  by
Section 7(b) (4), the Owner  Participant  shall not assign,  convey or otherwise
transfer all or any part of (including  without limitation an undivided interest
in) its right, title or interest in and to this Participation  Agreement, any of
the other Transaction Documents or the Trust Estate (except its right to receive
Excepted  Payments)  to any  Person  (a  Transferee)  except  on  the  following
conditions:

            (i) the  Transferee  shall  enter into an  agreement  or  agreements
        whereby such Transferee confirms that (1) it shall be bound by the terms
        of this Participation  Agreement and each other Transaction Document, to
        the extent of the  interest  transferred,  as if it had been  originally
        named as the Owner Participant  hereunder and thereunder and (2) if such
        Transferee is a public utility  company,  it shall have waived its right
        to claim  Special  Casualty  Value upon the  occurrence of a Deemed Loss
        Event (of the type  specified in clause (1) of the  definition  thereof)
        under the Facility Lease:

            (ii) the Transferee shall be either (A) a financial  institution,  a
        corporation or a partnership  with a net worth or capital and surplus of
        at least $25,000,000 (or, in the case of a partnership,  at least one of
        whose general partners has such a net worth or capital and surplus),  or
        a  direct  or  indirect  wholly  owned  subsidiary  of such a  financial
        institution  or  corporation,  (B) a direct  or  indirect  wholly  owned
        subsidiary of (1) the Owner Participant or (2) any parent of the

        Owner  Participant,  (C) the Lessee or such  other  Person as shall have
        been approved by the Lessee or (D) any Person;  provided,  however, that
        if the  Transferee is a subsidiary  referred to in clause (A) above or a
        Person  referred  to  in  clause  (D)  above,  the  transferring   Owner
        Participant (and any parent thereof  secondarily liable pursuant to this
        Section  15(a) (ii))  shall  continue to be liable for (or the parent of
        such Transferee,  which shall otherwise be a permitted Transferee, 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


            (iii) such  transfer  shall not  violate the  Securities  Act or any
        provision of, or create a  relationship  which would be in violation of,
        any  Applicable  Law  or  agreement  to  which  the  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  provisions  contained  in the first
sentence of this  Section  15(c)) is for the  benefit of the  Lessee,  the Owner
Trustee  and the Owner  Participant  and may not be  enforced by any other party
hereto.

            SECTION 16. Brokerage and Finders' Fees and Commissions

            Except to the  extent of amounts  payable  by the Owner  Participant
pursuant to Section 14, the Lessee will  indemnify  and hold  harmless  the Loan
Participant,  the Indenture Trustee, the Owner Trustee and the Owner Participant
in respect of any commissions,  fees,  judgments or other expenses of any nature
and kind which any of them may  become  liable to pay by reason of any claims by
or on behalf of brokers,  finders,  agents,  advisors or  investment  bankers in
connection with the transactions  contemplated by this Participation  Agreement,
any other Transaction  Document or any Financing Document,  or any litigation or
similar  proceeding arising from any such claim, other than those claims arising
out of written  undertakings  of the party claiming  indemnification  under this
Section 16 or any Affiliate or shareholder (or Affiliate of such shareholder) of
such Person with any such broker, finder, agent, advisor or investment banker.

          SECTION 17. Survival of Representations and Warranties; Binding Effect

            (a)  Survival.  All  indemnities,   representations  and  warranties
contained in this Participation Agreement, in any other Transaction Document, in
any Financing Document and in any agreement,  document or certificate  delivered
pursuant  hereto or  thereto  or in  connection  herewith  or  therewith,  shall
survive,  and shall continue in effect following,  the execution and delivery of
this  Participation  Agreement,  the  making  of the  investments  and the loans
referred to herein,  any disposition of any interest in the Undivided  Interest,
Unit 2 or any other property referred to in this Participation Agreement and the
expiration or other termination or any or the Transaction Documents or Financing
Documents  and  shall  be  and  continue  in  effect   notwithstanding  (i)  any
investigation  made by the Owner Participant or the Loan Participant or (ii) the
fact that any of the Indenture Trustee,  the Owner Trustee, the Loan Participant
or the Owner  Participant  may  waive  compliance  with any of the other  terms,
provisions  or  conditions  of any of the  Transaction  Documents  or  Financing
Documents.  The  obligations of the Lessee under Sections 10(b) (1) (ix),  10(b)
(2), 10(b) (3) (vii), 10(b) (3) (x) , 10(b) (3) (xi), 13, 14, 16 and 19(f) shall
survive the expiration or other termination of this  Participation  Agreement or
any other  Transaction  Document or  Financing  Document.  The  extension of 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.

            (b) Binding Effect. All agreements,  representations  and warranties
in  this  Participation  Agreement,  the  other  Transaction  Documents  and the
Financing  Documents and in any  agreement,  document or  certificate  delivered
concurrently with the execution of this Participation  Agreement or from time to
time  thereafter,  shall bind the party making the same and its  successors  and

its successors and permitted  assigns,  and, to the extent  provided in the next
sentence, each Indemnitee and its successors and assigns. The obligations of the
Lessee  under  Section  13  hereof  and  Section  20 of the  Facility  Lease are

            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

control of nor shall they be deemed to be under the control of any other  Person
having any  interest in Unit 2, 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 New York.

            (d)  Amendment,   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

                                      -87-

<PAGE>

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
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

                  SECTION   7.05.   Compensation.   As   compensation   for  its
obligations  under  Sections  7.02,  7.03 and 7.04, if no Event of Default based
upon PNM's  failure to perform  obligations  under  Section 5(a) of the Facility
Lease has occurred and is continuing,  PNM shall be entitled to receive, and the
Owner Trustee hereby agrees to pay, an amount equal to the Owner Trustee's Share

extent  reasonably  allocable to the  undivided  Interest and the Real  Property
Interest and (ii)  reasonable  compensation  for the Unit 2 Retained  Assets and

covenants  and agrees  that,  at all times during the Agency  Period,  the Owner
Trustee  shall  have the right to wheel,  under  normal  transmission  operating

under normal transmission  operating conditions,  over transmission equipment in
which PNM now owns or may hereafter acquire an ownership interest,  between Unit

                  (b) Based upon the respective  rights,  duties and obligations
of the Owner Trustee and PNM set forth in Section 7.06(a),  if PNM shall fail or
decline to give the notice of renewal of the  Facility  tease or purchase of the
Undivided  Interest,  in each case as provided in Section  13(a) of the Facility
Lease,  PNM and the Owner Trustee shall  forthwith  commence the  negotiation in
good faith of a definitive  transmission  agreement,  not inconsistent  with the
terms and provisions of Section 7.06(a),  but containing  sufficient  detail for
the proper  wheeling of power and energy,  under normal  transmission  operating
conditions,  over the equipment of PNM referred to in such Section 7.06(a) under
then existing  circumstances,  for the exercise or stipulation,  as the case may
be, of the respective  rights,  duties and  obligations of the Owner Trustee and
PNM set forth in Section 7.06(a).  PNM and the Owner Trustee shall complete such
negotiations  and execute such  definitive  transmission  agreement prior to the
Lease Termination Date and such definitive  transmission agreement shall provide
for  compensation to PNM for the  transmission  services so provided at the Fair
Market Sales Value thereof.
