                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


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


We have reviewed the accompanying  consolidated  balance sheet of Public Service
Company  of New  Mexico  (a  New  Mexico  corporation)  and  subsidiaries  as of
September  30,  1999 and the related  consolidated  statements  of earnings  and
comprehensive  income for the three-month and nine-month periods ended September
30,  1999 and  1998,  and the  consolidated  statements  of cash  flows  for the
nine-month periods ended September 30, 1999 and 1998. 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, 1998 (not presented herein),  and, in
our report  dated March 2, 1999,  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, 1998, 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)  Accounting Policies and Responsibilities for 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,  1998 (the "1998  Form  10-K")  filed with the
Securities  and  Exchange   Commission  ("SEC").   The  consolidated   financial
statements are unaudited and reflect all adjustments  (consisting only of normal
and recurring adjustments) that are, in the opinion of management, necessary for
a fair presentation of the financial  position and results of operations for the
interim periods presented.  The consolidated financial statements should be read
in  conjunction  with the  consolidated  financial  statements and notes thereto
contained  in the 1998 Form 10-K.  The results of  operations  for the three and
nine months  ended  September  30, 1999 are not  necessarily  indicative  of the
results for the entire year ending December 31, 1999.  Certain 1998 amounts have
been reclassified to conform to the 1999 financial statement presentation.

(2)  Accounting Changes

Effective  January 1, 1999,  the  Company  adopted  Emerging  Issues  Task Force
("EITF") Issue No. 98-10,  Accounting  for Contracts  Involved in Energy Trading
and Risk  Management  Activities.  EITF Issue No. 98-10 requires gains or losses
resulting  from the market  value  changes  on energy  trading  contracts  to be
recorded in earnings.  The effect of the initial  application  of EITF Issue No.
98-10 is reported as a  cumulative  effect of a change in  accounting  principle
which  increased the Company's  consolidated  net income by  approximately  $3.5
million  (after related income tax expense of  approximately  $2.3 million),  or
$.09 per common share.

(3)  Earnings Per Share

The following table provides a reconciliation between basic and diluted earnings
per share for the periods ended:

(4)  Segments Information

The Company's  principal  business  segments are electric  ("Electric")  and gas
("Gas") operations. Electric consists of three major business lines that include
the  Electric  Service  Business  Unit  ("Distribution"),  Transmission  Service
Business Unit ("Transmission") and Bulk Power Business Unit ("Generation").  The
unregulated  segments  include the  operation  of Avistar,  Inc.  and  corporate
administrative  functions.  Intersegment  revenues  are  determined  based  on a
formula  mutually  agreed upon  between  affected  segments and are not based on
market rates. Intersegment revenues are eliminated for consolidation purposes.

Summarized  financial  information by business  segment for the three months and
nine months ended September 30, 1999 and 1998 is as follows:

(5)  Financial Instruments

The Company uses derivative financial instruments in limited instances to manage
risk as it relates to changes in natural  gas and  electric  prices and  adverse
market changes for investments held by the Company's various trusts. The Company
is exposed to credit losses in the event of  non-performance  or  non-payment by
counterparties.  The  Company  uses a credit  management  process  to assess and
monitor the financial conditions of counterparties.  The Company also uses, on a
limited basis, certain derivative instruments for bulk power electricity trading
purposes in order to take  advantage of  favorable  price  movements  and market
timing activities in the wholesale power markets.

Natural Gas Contracts

Pursuant  to an  order  issued  by the  New  Mexico  Public  Utility  Commission
("NMPUC"),  predecessor to New Mexico Public Regulation  Commission ("PRC"), the
Company has previously  entered into swaps to hedge certain  portions of natural
gas supply  contracts in order to protect the  Company's  natural gas  customers
from the risk of adverse  price  fluctuations  in the natural  gas  market.  The
financial  impact of all hedge  gains and losses from swaps  flowed  through the
Company's  purchased  gas  adjustment  clause.  As a result,  earnings  were not
affected by gains or losses generated by these  instruments.  The Company hedged
40% of its natural gas deliveries during the 1998-1999 heating season. Less than
15.5% of the  1998-1999  heating  season  portfolio  was hedged using  financial
hedging  contracts.  The Company has hedged a portion of its  1999-2000  heating
season gas supply  portfolio  through  the use of both  physical  and  financial
hedging  tools.  Less  than  9.1%  of the  Company's  1999-2000  heating  season
portfolio is hedged using financial hedging contracts. As of September 30, 1999,
the Company had  unrecognized  mark-to-market  gains of $0.5 million  associated
with its gas-related financial hedging activities.

Electricity Trading Contracts

To take advantage of market opportunities  associated with the purchase and sale
of electricity, the Company's wholesale power operation periodically enters into
derivative  financial  instrument  contracts.  The  Company  accounts  for these
financial  instruments as trading activities under the accounting guidelines set
forth under EITF Issue No. 98-10. As a result,  all open contracts are marked to
market at the end of each period.  These contracts may be in the form of futures
and are required to be reflected on the balance  sheet at fair market value with
resulting  gains and losses  recognized  in earnings.  In addition,  the Company
enters into forward  physical  contracts and physical  options.  Those contracts
that meet the  criteria  for trading  activities  under EITF Issue No. 98-10 are
marked to market and reflected on the balance sheet. The physical  contracts are
subsequently  recognized as revenues or purchased power when the actual physical
delivery occurs.


                                       10
<PAGE>

Through September 30, 1999, the Company's  wholesale electric trading operations
settled trading contracts for the sale of electricity that generated $34 million
of electric  revenues by delivering  820 million KWh. The Company  purchased $36
million or 1,046 million KWh of  electricity to support these  contractual  sale
and other open market sales opportunities. Energy purchases for trading purposes
are included in the cost of energy sold.

As of September 30, 1999, the Company had open trading contract positions to buy
$21.5 million and to sell $20.8 million of  electricity.  At September 30, 1999,
the Company had a gross  mark-to-market  gain (asset  position) on these trading
contracts of $8.2 million and gross  mark-to-market loss (liability position) of
$3.8 million, with net mark-to-market gain (asset position) of $4.4 million. The
mark-to-market valuation is recognized in earnings each period.

Corporate Hedge

The Company has about $62 million  invested in domestic stocks in various trusts
for nuclear decommissioning,  executive retirement and retiree medical benefits.
At the end of March 1999, the Company began using financial derivatives based on
the  Standard  & Poor's  ("S&P")  500  Index to  limit  potential  loss on these
investments due to adverse market fluctuations.  The options are structured as a
collar,  protecting  the portfolio  against  losses beyond a certain  amount and
balancing  the cost of that  downside  protection  by  foregoing  gains  above a
certain  level.  If the S&P 500 Index is within  the  specified  range  when the
option contract expires,  the Company will not be obligated to pay, nor will the
Company  have the right to receive  cash.  The Company  accounts  for the market
value changes of these options  under  mark-to-market  accounting on a quarterly
basis.  At September 30, 1999, the Company  recorded an unrealized  year-to-date
gain of $0.7 million  (pre-tax) on the market value of these  options,  although
the S&P 500 Index is still within the specified range of the collar.

(6)  Accounting Pronouncements

EITF Issue No.  99-14,  Recognition  of  Impairment  Losses on Firmly  Committed
Executory  Contracts:  The EITF has  added an  issue to its  agenda  to  address
impairment  of leased  assets.  A significant  portion of the Company's  nuclear
generating  assets is held  under  operating  leases.  Based on the  alternative
accounting  methods being explored by the EITF, the related  financial impact of
the future adoption of EITF No. 99-14 could potentially be significant. However,
a complete  evaluation of the financial  impact from the future adoption of EITF
Issue No. 99-14 will be  undeterminable  until EITF  deliberations are completed
and stranded cost recovery issues are resolved.

Statement of Financial  Accounting  Standards ("SFAS") No. 137 -- Accounting for
Derivative  Instruments and Hedging Activities--  Deferral of the Effective Date
of SFAS No. 133: SFAS No. 133  establishes  accounting  and reporting  standards
requiring  every  derivative  instrument  to be recorded in the balance sheet as
either an asset or  liability  measured at its fair value.  The  Statement  also
requires that changes in the derivatives' fair value be recognized  currently in
earnings  unless specific hedge  accounting  criteria are met. The Company is in
the  process  of  reviewing  and  identifying  financial  instruments  currently
existing in the Company for compliance  with the provisions  SFAS No. 133. It is
likely that the adoption of SFAS No. 133 will add  volatility  to the  Company's
operating  results  and/or asset and  liability  valuations.  In June 1999,  the
Financial  Accounting Standards Board issued SFAS No. 137 to amend the effective
date for compliance with SFAS No. 133 to January 1, 2001.

(7)  Commitments and Contingencies

There are various claims and lawsuits pending against the Company and certain of
its  subsidiaries.  The  Company  is also  subject to  Federal,  state and local
environmental  laws  and  regulations,  and is  currently  participating  in the
investigation  and  remediation  of numerous  sites.  In  addition,  the Company
periodically  entered into  financial  commitments  in connection  with business
operations.  It is not possible at this time for the Company to determine  fully
the effect of all litigation on its consolidated financial statements.  However,
the Company has recorded a liability  where such litigation can be estimated and
where an outcome is  considered  probable.  The Company does not expect that any
known lawsuits, environmental costs and commitments will have a material adverse
effect on its financial condition or results of operations.

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

The Company's  1998 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 three
months and nine months ended  September  30, 1999 and 1998. It should be read in
conjunction with the Company's  consolidated  financial  statements and PART II,
ITEM 1 -- LEGAL  PROCEEDINGS.  Trends and contingencies of a material nature are
discussed to the extent known and considered relevant.

                              RESULTS OF OPERATIONS

                  For the Three Months Ended September 30, 1999

Consolidated  Results - Net earnings of $21.4  million or $0.52 per common share
decreased  $10.6  million  ($0.24 per common share  including  the effect of the
stock purchase) for the quarter.  The decline reflects the negative effects that
mild weather and the rate  reduction  that began in late July had on operations.
The following discussion highlights  significant items that affected the results
of operations for the quarter ended September 30, 1999 versus 1998.

Operating  revenues grew $20.2 million  (6.3%) for the quarter to $340.6 million
reflecting strong wholesale  electric sales. See the electric and gas operations
sections below for further discussions.

Total  operating  expenses grew $37.7 million  (13.7%) to $310.3 million for the
quarter.  The cost of energy sold (which  includes  coal,  nuclear fuel, gas and
electricity  purchased for resale)  increased  $41.1  million  (29.4%) to $180.7
million,  reflecting  an 18.6%  growth in  wholesale  electric  volumes,  a 5.1%
increase in gas sales volumes, higher prices for elecricity purchased for resale
and open market energy  purchases  used to  supplement  the Company's own energy
production capability due to scheduled and unscheduled electric generation plant
outages.  Administrative  costs  increased $5.0 million (13.4%) to $42.1 million
due to costs associated with the implementation of a new customer billing system
and costs  incurred  to support  the  formation  of a new  holding  company.  In
addition,  depreciation expense grew $2.8 million  period-over-period  caused by
continuing  capital  investments  and a first  quarter  1999  depreciation  rate
change.  These cost increases were partially  offset by lower taxes due to lower
pre-tax income levels and lower energy production costs.



                                       13
<PAGE>

Operating income decreased $17.2 million (36.2%) to $30.3 million as margins for
both the gas and  electric  businesses  were hurt by weak  market  pricing,  the
electric rate reduction,  mild weather  conditions and excess electricity supply
in the Company's key markets.

Other  income and  deductions,  net of taxes,  increased  $4.0  million  for the
quarter to $8.5 million due to the  recording  of interest  income from the Palo
Verde Nuclear  Generating  Station  ("PVNGS") Capital Trust and a mark-to-market
gain on the  corporate  investment  collar (see note 5 to Notes to  Consolidated
Financial Statements).

Electric  Operations - Net earnings  from  electric  operations of $25.3 million
decreased $13.2 million (34.3%) for the quarter,  reflecting  weather conditions
and the rate reduction.  The following discussion  highlights  significant items
that affected the results of operations of the electric business for the quarter
ended September 30, 1999 versus 1998.

Operating  revenues grew $19.1 million  (6.8%) for the quarter to $299.8 million
as a 18.6% improvement in wholesale  electricity sales volume was only partially
offset by the  implementation  of a new rate order in late July 1999 (which will
lower rates by $37 million  annually based on current  customer base) and a 1.3%
decline in retail  megawatt hour ("MWh") sales for the quarter due to mild local
weather conditions. The Company delivered wholesale (bulk) power of 3.61 million
MWh of  electricity  this year compared to 3.04 million MWh delivered last year.
Total  electricity  delivery was 5.51 million MWh compared to 4.97 MWh delivered
last year, a 10.9% improvement.

Total  operating  expenses grew $35.2  million  (15.1%)  caused  primarily by an
increases  in  the  cost  of  energy  sold  of  $41.5  million  as a  result  of
volume-related  increases  in power  purchased  for resale at higher  prices and
higher administrative costs of $4.0 million due to Y2K compliance costs, holding
company  formation  costs and new customer  billing system  installation  costs.
Depreciation and amortization  expense increased $1.3 million for the quarter to
$18.3 million due to additions to the plant base and the 1999 rate change.

Operating   income  taxes  decreased  $9.0  million  (41.1%)  to  $12.9  million
reflecting  decreased  electric gross margin (electric  operating  revenues less
fuel and purchased  power expense) of $22.4 million for the quarter.  The margin
decrease was attributable to increased  purchased power expense (higher purchase
costs  and  volume  growth)  and  decreased  retail  sales  due to mild  weather
conditions.

Gas  Operations - Gas  operations had a net loss of $2.8 million for the quarter
compared with a net loss of $0.02  million a year ago. The following  discussion
highlights  significant  items that  affected the results of  operations  of gas
operations for the quarter ended September 30, 1999 versus 1998.



                                       14
<PAGE>

Operating  revenues  declined  $1.1  million  (2.7%)  for the  quarter  to $38.2
million.  This decline was driven by a 15.7% decline in the average rate charges
per decatherm (due to weak gas prices).  Price declines were partially offset by
a 5.1% volume improvement,  as residential and commercial business posted double
digit growth and transportation volume growth of 21.1%.

Total operating  expenses  increased $2.2 million (6.1%) caused by increased gas
costs of $0.9 million,  higher  administrative costs of $1.6 million largely due
to  the  new  customer   billing  system   installation   costs)  and  increased
depreciation and amortization expense of $1.6 million.

Operating  income  decreased  $3.3  million  to a loss  of $0.7  million  due to
depressed  gas gross  margin (gas  operating  revenues  less gas  purchased  for
resale) of $2.0 million and increased operating expenses discussed above.

Discontinued  Operations  - In  August  1998,  the  Company  adopted  a plan  to
discontinue the natural gas trading  operations of its Energy Services  Business
Unit and completely  discontinue  these operations on December 31, 1998.  Losses
from discontinued operations, net of taxes, for the three months ended September
30, 1998,  were $2.7 million,  or $0.07 per common  share.  These losses did not
recur in 1999.

                  For the Nine Months Ended September 30, 1999

Consolidated  Results - Net earnings of $66.2  million or $1.60 per common share
decreased  $1.7  million  ($0.02 per common  share  including  the effect of the
second  quarter stock  purchase) for the period.  The decline was driven by mild
weather  conditions  that weakened market prices and the electric rate reduction
implemented in late July. The following discussion highlights  significant items
that affected the results of operations for the nine months ended  September 30,
1999 versus 1998.

Operating  revenues  grew $41.3  million  (5.0%)  for the nine  months to $874.8
million.  The growth in revenues  was led by a 27.4%  improvement  in  wholesale
electric  power sales  volumes (8.25 million MWh in 1999 versus 6.47 million MWh
in 1998) as the Company continued to expand its power trading operations. Retail
sales volumes also improved slightly  year-over-year.  These volume improvements
were  partially  offset by residential  (down 1.4%) and  commercial  (down 0.9%)
price decreases due to the rate reduction implemented in late July.

Total  operating  expenses grew $56.8 million  (7.9%) to $780.2  million for the
period.  The cost of energy sold increased  $51.3 million  (14.8%)  reflecting a
27.4% rise in wholesale electricity sales, a 1.5% increase in gas throughput and
higher  unit  costs   associated   with   electricity   purchased   for  resale.
Administrative  expenses grew $13.4 million (13.5%) to $112.7 million due to the
non-recurring   effect  of  Year  2000  ("Y2K")   costs,   new  billing   system
implementation   costs  and  holding  company   formation  costs.  In  addition,
depreciation  expense  grew  $7.2  million  as a  result  of  continued  capital
investment and higher 1999  depreciation  rates.  These increases were partially
offset by lower taxes reflecting lower pre-tax income.

                                       15
<PAGE>

Operating  income for the current  period  decreased  $15.5 million  (14.25%) to
$94.6 million from a year ago,  reflecting a 4.3% margin  decline caused by weak
market prices in the Company's  wholesale  power market,  weak first quarter gas
demand due to mild weather and higher administrative costs.

Other income and deductions, net of taxes, increased $8.7 million for the period
to $20.9 million due to the recording of interest  income from the PVNGS Capital
Trust  and a gain  resulting  from  closing  down of the coal  mine  reclamation
activities.

Net interest charges increased $7.2 million for the period to $52.8 million as a
result of the issuance of $435 million in senior unsecured notes in August 1998,
partially offset by a decrease in short-term debt interest charges.

Discontinued  Operations  - In  August  1998,  the  Company  adopted  a plan  to
discontinue the natural gas trading  operations of its Energy Services  Business
Unit and completely  discontinue  these operations on December 31, 1998.  Losses
from discontinued operations,  net of taxes, for the nine months ended September
30, 1998,  were $8.7 million,  or $0.21 per common  share.  These losses did not
recur in 1999.

Cumulative  Effect of a Change in  Accounting  Principle - Effective  January 1,
1999,  the  Company  adopted  EITF Issue No.  98-10.  The effect of the  initial
application  of the new standard is reported as a cumulative  effect of a change
in accounting principle.  As a result, the Company recorded additional earnings,
net of taxes,  of  approximately  $3.5 million,  or $0.09 per common  share,  to
recognize  the  gain  on  net  open  physical  electricity  purchase  and  sales
commitments considered to be trading activities.

                         LIQUIDITY AND CAPITAL RESOURCES

Cash Activity - Cash  generated  from  operating  activities  of $149.4  million
decreased $7.2 million  (4.6%) from last year. The reduction in cash  generation
reflects an $18.7 million  increase in customer  accounts  receivable  caused by
collection  delays generated by  implementation of a new customer billing system
and higher  overall sales  volumes.  In addition,  1999 earnings  include a $3.5
million non-cash gain from implementation of new accounting methods.  These cash
uses were partially  offset by cash generation  from lower inventory  levels and
higher non-cash depreciation charges.



                                       16
<PAGE>

Cash used for investing  activities was $20.7 million in 1999 compared to $302.6
million  in 1998.  This  decreased  spending  reflects  the  absence of the 1998
purchases of $215.7 million in PVNGS lease obligation bonds,  lower construction
expenditures  in 1999 of $28.9 million and the  liquidation  of  insurance-based
investments in the nuclear decommissioning trust of $26.6 million (see financing
activities below for the payment of decommissioning debt of $26.6 million).

Cash used for financing  activities  was a use of $101.4 million in 1999 because
of the repurchase of $31.6 million of senior unsecured  notes,  $26.6 million of
loan repayments  associated with nuclear  decommissioning  trust  activities and
$17.7 million stock repurchase by the Company. Cash from financing activities in
1998  included  proceeds from the issuance of senior  unsecured  notes of $429.4
million and repayment of short-term borrowings of $211.8 million.

Capital Requirements - The projection for total capital requirements for 1999 is
$176 million, which includes $145 million of utility construction  expenditures.
During the nine month period, the Company spent  approximately $98.3 million for
capital requirements and anticipates  spending  approximately $50.2 million over
the remainder of 1999. The Company expects that these cash  requirements will be
met  primarily  through  internally   generated  cash.  However,  to  cover  the
difference in the amounts and timing of cash  generation and cash  requirements,
the  Company  intends  to  utilize  short-term  borrowings  under its  liquidity
arrangements.  These  estimates  are under  continuing  review  and  subject  to
on-going adjustment based upon business needs and market conditions.

Stock  Repurchase - In March 1999, the Company's  board of directors  approved a
plan to repurchase up to 1,587,000  shares of the Company's  outstanding  common
stock with maximum  purchase price of $19.00 per share.  The repurchase  program
was created to facilitate the Company's  stock option  program.  As of September
30,  1999,  the  Company  repurchased  one  million  shares  of  its  previously
outstanding  common  stock  at a cost of $17.7  million.  The  Company  may from
time-to-time repurchase additional common stock for various corporate purposes.

Financing and Liquidity - In 1999, the Company retired $31.6 million of its 7.1%
senior unsecured notes through open market  purchases,  utilizing the funds from
operations  and the funds  from  temporary  investments.  On October  28,  1999,
tax-exempt  pollution  control  revenue  bonds of $11.5 million with an interest
rate of 6.60% were issued to partially  reimburse  the Company for  expenditures
associated  with its  share of a  recently  completed  upgrade  of the  emission
control system at San Juan Generating Station ("SJGS").
The  Company  does not have any  additional  long-term  financing  plans for the
remainder of 1999.



                                       17
<PAGE>


As of September 30, 1999, the Company had $405.0 million of available  liquidity
arrangements,  consisting of $300.0 million from an unsecured  revolving  credit
facility,  $80.0 million from an accounts  receivable  securitization  and $25.0
million in local bank lines of credit.  At September  30, 1999,  the Company did
not have any  short-term  borrowings and had $90.4 million in cash and temporary
investments.

The Company's  ability to finance its construction  program at a reasonable cost
is dependent largely upon its earnings, credit ratings, regulatory approvals and
financial  market  conditions.  In August 1999, two major credit rating agencies
upgraded the Company's  securities to  investment  grade  following the electric
rate order by the PRC,  approving the rate case  settlement.  (See Item 5. Other
Events - "Upgrades of the Company's  Securities  Ratings to Investment Grade" in
the Current Report on Form 8-K dated September 2, 1999.)

                         OTHER ISSUES FACING THE COMPANY

Formation of Holding Company

The Electric  Utility  Industry  Restructuring  Act of 1999 (the  "Restructuring
Act") opens the state's  electric  power market to customer  choice in 2001. The
Restructuring  Act  requires  that  assets  and  activities  subject  to the PRC
jurisdiction,  primarily electric and gas distribution,  and transmission assets
and activities (collectively, the "regulated business"), be separated from other
competitive  business,  primarily  electric  generation  and service and certain
other  energy  services  (collectively,   "the  competitive  businesses").  Such
separation is required to be  accomplished  through the creation of at least two
separate  corporations.  The  Company  has decided to  accomplish  the  mandated
separation  by the  formation  of a  holding  company  and the  transfer  of the
regulated businesses to a newly-created, wholly owned subsidiary of such holding
company,  subject to various regulatory  approvals.  Corporate separation of the
regulated business from the competitive  businesses must be completed by January
1,  2001,  although  such  date  may be  extended  by up to one year by the PRC.
Completion of corporate separation will require a number of regulatory approvals
by, among others, the PRC and the Nuclear Regulatory Commission. Completion will
also require shareholder  approval and a number of other consents from creditors
and lessors.  Completion may also entail  significant  restructuring  activities
with respect to the Company's existing liquidity  arrangements and the Company's
publicly-held senior unsecured notes of which $403.4 million were outstanding as
of September 30, 1999.  Holders of the Company's senior  unsecured  notes,  $135
million at 7.5% and $268.4  million at 7.1%,  may be offered the  opportunity to
exchange  their  securities  for  similar  senior  unsecured  notes of the newly
created regulated business.




                                       18
<PAGE>



On  September  30,  1999,  the  Board of  Directors  of the  Company  authorized
management to commence the process of obtaining  necessary  regulatory and other
approvals so that corporate  separation  could occur in advance of the statutory
deadline  of January 1, 2001 and in advance of  approval  of the  balance of the
Company's  transition plan under the Restructuring Act. The Company  anticipates
filing its  application  with the PRC for necessary  authorizations  in the near
future.

Regulated Business

The regulated business comprised approximately 47% of the Company's total assets
and  contributed  approximately  41% of the  Company's  operating  revenues  and
approximately 49% of the Company's income before interest charges in 1998.

Stranded Costs

The Restructuring  Act recognizes that electric  utilities should be permitted a
reasonable  opportunity to recover an  appropriate  amount of the costs incurred
previously in providing  electric  service  ("stranded  costs").  Stranded costs
include plant decommissioning costs,  regulatory assets, lease and lease-related
costs recognized under cost-of-service regulation.  Utilities will be allowed to
recover no less than 50% of such costs  through a  non-bypassable  charge on all
customer bills for five years after  implementation of customer choice.  The PRC
could authorize a utility to recover up to 100% of its stranded costs if the PRC
finds that  recovery of more than 50%:  (i) is in the public  interest;  (ii) is
necessary to maintain the financial  integrity of the public  utility;  (iii) is
necessary to continue adequate and reliable service;  and (iv) will not cause an
increase  in rates  to  residential  or  small  business  customers  during  the
transition  period.  Utilities will also be allowed to recover in full any costs
incurred in implementing full open access ("transition  costs").  The transition
costs will be recovered  through 2007 by means of a separate wire charge.  While
recoverable stranded costs and transition costs will be collected as part of the
regulated business, it is anticipated that such collections would be paid to the
Company and be part of the  revenues  available  to the  competitive  businesses
subsequent to restructuring.

Competitive Businesses

The  competitive  businesses  which would be retained by the Company include the
Company's interests in generation facilities,  including PVNGS, the Four Corners
Power Plant ("Four  Corners"),  and SJGS,  together with the  pollution  control
facilities  which have been  financed  with  pollution  control  revenue  bonds.
Approximately  $586 million in pollution  control  revenue bonds would remain as
obligations  of  the  generation  subsidiary,  as  would  certain  other  of the
Company's long-term obligations. The competitive businesses would not be subject
to regulation by the PRC. Under the Company's  restructuring plan, the Company's
bondholders  will  continue  to  hold  obligations  of  the  Company   following
restructuring.  Since the Restructuring Act requires  significant changes in the
assets and  businesses  of the Company,  the  bondholders  will be accepting the
risks involved in those changes.



                                       19
<PAGE>

The Company will continue its competitive  business following the restructuring,
which will be subject to market conditions. Following the separation as required
by the Restructuring  Act, in support of its wholesale trading  operations,  the
Company is  targeting  to double its  generating  capacity  and triple its sales
volume. Recently, the Company formed a non-regulated  subsidiary,  Avistar, Inc.
("Avistar") in August 1999, to achieve competitive business strategies.  Avistar
provides  services in the areas of utility  management  for  municipalities  and
other  communities,  remote metering and development of energy  conservation and
supply  projects  for  federal  government  facilities.  The  Company  does  not
anticipate an earnings contribution from Avistar over the next few years.

Financial Options

Funds generated from  capitalizing the new regulated and competitive  businesses
and/or  from  potential  stranded  cost  recovery  may be used by the Company to
retire or restructure currently outstanding debt obligations,  to repurchase the
Company's  outstanding equity securities or to fund business expansion.  In this
regard,  the Company announced a five-year strategy to invest up to $600 million
to expand its power generation  portfolio to support its asset-backed  wholesale
electricity  sales  operations and expand the geographic range of its generation
operations  into new markets.  A  significant  portion of the  Company's  recent
revenue and earnings  growth has been  generated  from the  Company's  wholesale
electricity trading operations.  The expansion strategy is focused on developing
opportunities to expand these operations.

Risk of Deregulation

Deregulation in the electric  utility is likely to have a significant  impact on
the price for electric  generation  and recovery of the  investment  in electric
generation  assets.  Such price  pressures  will likely put a strain on electric
generation margins. In response to competition and the need to gain economies of
scale,  electricity  producers  will need to control costs to maintain  margins,
profitability and cash flow that will be adequate to support  investments in new
technology  and  infrastructure.  As a  result,  the  uncertainties  surrounding
deregulation  and the  Company's  ability  to be  competitive  in a  deregulated
environment could be significant  business risks for the Company as deregulation
and possible industry consolidation continue to evolve.




                                       20

New Customer Billing System

As previously  reported,  the Company installed a new customer billing system in
November  1998,  for  which  the  Company  has  had  a  significant   number  of
implementation  issues. (See "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION  AND RESULTS OF  OPERATIONS  -- OTHER ISSUES FACING THE COMPANY -- NEW
CUSTOMER  BILLING  SYSTEM" in the quarterly  report on Form 10-Q for the quarter
ended June 30, 1999.)

On October 1, 1999,  the Company and the PRC Staff  entered  into a  stipulation
that would allow the Company to bill an additional  service  charge to customers
who were not billed the appropriate  electric  service charges and/or gas access
fees.  The  one-time  charge  will be equal  to or less  than  the  amount  that
customers would have otherwise been billed had their bills not been delayed.  On
October 14, 1999, at the conclusion of a hearing, the hearing examiner announced
that he would certify the stipulation to the PRC for approval and on October 20,
1999,  the  hearing  examiner  issued a  certification  of the  stipulation.  On
November 2, 1999, the PRC approved the stipulation, concluding the investigation
without  imposing  any  civil  penalty  on the  Company.  Under  the  stipulated
agreement,  the  Company is allowed to  collect  approximately  $0.7  million in
unbilled  electric  service  charges  and gas access  fees in the  November  and
December billing cycles.

Because of the implementation issues associated with the new billing system, the
Company was  estimating  retail gas and  electric  revenues  through  July 1999.
Beginning with the August  financial  reports,  the Company was able to generate
reports  produced by the new billing  system  that  reflect the actual  revenues
billed for all  subsequent  months.  The  Company now is in the process of fully
reconciling previously estimated revenues to those actually billed to customers.
The  Company's  financial,  tax and  regulatory  reports  have  reflected  these
estimates.  Management  does not believe that the  estimation on the  subsequent
reconciliation  process  will have a material  adverse  effect on the  Company's
results of operations or financial condition.

The Year 2000 ("Y2K") Issues

As previously reported, the Y2K issue is a consequence of computer programs ("IT
Systems")  written  using  two  digits  rather  than four  digits to define  the
applicable  year.  The  Company  adopted  a plan to  address  the Y2K  issue for
internal systems and external dependencies.  In June 1999, the Company reported,
as required, to the North American Electric Reliability Council ("NERC") that it
believes its mission  critical  systems used to produce and deliver  electricity
are Y2K ready,  without any exceptions.  On July 2, 1999, the Company  announced
that it believes its mission critical systems used to produce electricity and to
deliver gas and electricity are Y2K ready. The Company's  remaining  non-mission
critical  systems had been scheduled to be Y2K ready by October 1, 1999, but not


                                       21
<PAGE>


all of those systems met that deadline. Several systems have been delayed due to
vendor  delivery  problems or  remediation  delays.  The Company  expects  these
non-mission critical systems to be Y2K ready by December 31, 1999. None of these
systems have any direct impact on the  production of electricity or the delivery
of gas or electricity to customers. (See ITEM 2. -- "MANAGEMENT'S DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- OTHER ISSUES FACING
THE COMPANY -- THE YEAR 2000 ISSUE" in the  Company's  quarterly  report on Form
10-Q for the quarter ended June 30, 1999.)

The estimated status of each phase as of October 31, 1999, is set out below:

                                                      Estimated Status of

     Company-Wide Testing Phase                               91%

        *  The stated percentages  represent the status of completion as of
           October  31,  1999,  of all  of the  Company's  IT  Systems  and
           Embedded  Systems,   including  mission  critical  systems.  For
           purposes  of  this  presentation,   "mission  critical  systems"
           include  systems whose failures could cause an  interruption  in
           the supply of  electricity  or gas to the  Company's  customers,
           could interfere with the Company's  ability to communicate  with
           customers, or could interfere with the Company's cash flow.

The  Company  has a 10.2%  undivided  interest  in PVNGS,  with  portions of its
interest  held  under  leases.  Arizona  Public  Service  Company  ("APS"),  the
operating  agent of PVNGS,  notified  the U. S.  Nuclear  Regulatory  Commission
("NRC") on June 26, 1999 that PVNGS is Y2K ready.

Although the mission critical  systems are Y2K ready,  work will continue on the
development and testing of the Company's  contingency  plans.  Contingency plans
for mission  critical  systems  were  completed  on July 30,  1999.  The Company
participated in the successful  September  drills  organized by the NERC and the
Western Systems  Coordinating  Council,  with valuable lessons being learned and
changes  to  be  implemented  for  future  drills.   Testing  of  the  Company's
contingency plans will continue into November and December 1999. The Company has
completed  the  remediation  and testing of its prior energy  management  system
("EMS") and it is now Y2K ready.  In  addition,  the Company has  completed  the
testing and  installation of an upgraded EMS that is also Y2K ready. The Company
has also  developed and is testing a process to switch from the upgraded  system
to the prior system in case of a system failure.


                                       22
<PAGE>

The Company  has spent  approximately  $12.2  million on  non-PVNGS  Y2K related
activities during the first nine months of 1999, and approximately $17.5 million
since project  commencement.  The Company's share of the PVNGS costs  associated
with the Y2K project is deemed to be immaterial.

The  statements  in this section are Y2K readiness  disclosures  pursuant to the
Year 2000 Information and Readiness Disclosure Act.

Labor Union Negotiations

The Company and International  Brotherhood of Electrical  Workers ("IBEW") Local
Union 611 will enter into  negotiations  for a  successor  agreement  during the
later  part of the first  quarter of 2000.  The  current  collective  bargaining
agreement,  which covers the 654  bargaining  unit  employees  in the  Company's
regulated operations,  expires on May 1, 2000. The Company's negotiating team is
currently  preparing  for the  upcoming  negotiations.  The  outcome  of  future
negotiations cannot be determined at this time.

Accounting Standards

EITF Issue 99-14, Recognition of Impairment Losses on Firmly Committed Executory
Contracts:  The  Emerging  Issues Task Force  ("EITF") has added an issue to its
agenda to address  impairment of leased  assets.  A  significant  portion of the
Company's nuclear  generating  assets are held under operating leases.  Based on
the  alternative  accounting  methods  being  explored by the EITF,  the related
financial  impact  of  the  future  adoption  of  EITF  Issue  No.  99-14  could
potentially  be  significant.  However,  a complete  evaluation of the financial
impact from the future  adoption of EITF Issue No. 99-14 will be  undeterminable
until EITF  deliberations  are completed  and stranded cost recovery  issues are
resolved.

Statement of Financial  Accounting  Standards ("SFAS") No. 137 -- Accounting for
Derivative  Instruments and Hedging Activities--  Deferral of the Effective Date
of SFAS No. 133: SFAS No. 133  establishes  accounting  and reporting  standards
requiring every derivative instrument be recorded in the balance sheet as either
an asset or liability  measured at its fair value.  The Statement  also requires
that changes in the derivatives' fair value be recognized  currently in earnings
unless specific hedge accounting criteria are met. The Company is in the process
of reviewing and identifying all financial instruments currently existing in the
Company in compliance with the provisions of SFAS No. 133. It is likely that the
adoption of SFAS No. 133 will add volatility to the Company's  operating results
and/or  asset and  liability  valuations.  In June  1999,  Financial  Accounting
Standards  Board  issued  SFAS  No.  137 to  amend  the  effective  date for the
compliance of SFAS No. 133 to January 1, 2001.

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. Words
such as "estimates," "expects,"  "anticipates," "plans," "believes," "projects,"
and similar expressions identify forward-looking  statements.  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  costs;  (iv) the  inability  of the  Company to  successfully  compete
outside its  traditional  regulated  market;  (v) the  success of the  Company's
expansion  strategies;  (vi) regional  economic  conditions,  which could affect
customer growth; (vii) adverse impacts resulting from environmental regulations;
(viii) loss of  favorable  fuel supply  contracts;  (ix) failure to obtain water
rights  and  rights-of-way;   (x)  operational  and  environmental  problems  at
generating  stations;  (xi) the cost of debt and equity  capital;  (xii) weather
conditions; and (xiii) technical developments in the utility industry.

The costs of the  Company's  Y2K  Project  and the  dates on which  the  Company
believes it will complete the phases of the Project are based upon  management's
best estimates,  which were derived using numerous assumptions  regarding future
events,  including the continued availability of certain resources,  third-party
remediation  plans,  and other  factors.  There can be no  assurance  that these
estimates will prove to be accurate and actual  results could differ  materially
from  those  currently  anticipated.  Specific  factors  that  could  cause such
material  differences include, but are not limited to, the availability and cost
of personnel trained in Y2K issues, the ability to identify,  assess,  remediate
and test all  relevant  computer  codes and  embedded  technology,  and  similar
uncertainties.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company uses derivative financial instruments in limited instances to manage
risk as it relates to changes in natural  gas and  electric  prices and  adverse
market changes for investments held by the Company's various trusts. The Company
is exposed to credit losses in the event of  non-performance  or  non-payment by
counterparties.  The  Company  uses a credit  management  process  to assess and


                                       24
<PAGE>

monitor the financial conditions of counterparties.  The Company also uses, on a
limited basis, certain derivative instruments for bulk power electricity trading
purposes in order to take  advantage of  favorable  price  movements  and market
timing  activities  in the  wholesale  power  markets.  See  Note 5 to  Notes to
Consolidated Financial Statements for the Company's market risk information.

PART II -- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

San Diego Gas Electric Company ("SDG&E") Complaints

As previously  reported,  SDG&E has filed four  separate and similar  complaints
with the FERC,  alleging  that certain  charges under the Company's 100 MW power
sales agreement with SDG&E were unjust,  unreasonable and unduly discriminatory.
The Company filed responses to such complaints  denying the allegations  made by
SDG&E,  requesting  they be  dismissed.  (See PART II, ITEM 7. --  "MANAGEMENT'S
DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF  OPERATIONS  --
OTHER ISSUES FACING THE COMPANY -- NMPUC REGULATORY  ISSUES -- SAN DIEGO GAS AND
ELECTRIC  COMPANY  ("SDG&E")  COMPLAINTS" in the Company's 1998 annual report on
Form 10-K.)

On  March  11,  1999,  the FERC  issued  two  separate  orders  regarding  these
complaints.  One order,  among other things,  dismissed the first two complaints
filed by SDG&E.  In dismissing  the first two  complaints,  the FERC stated that
SDG&E had not presented  sufficient  evidence to warrant a hearing regarding the
reasonableness  of the contract  rate.  The order also ruled that an appropriate
time frame for  evaluating the  reasonableness  of the contract rate is over the
life of the contract rather than a snapshot of the rate on a year-to-year  basis
as SDG&E alleged in the first two complaints.  The second order  established the
refund period for the latest complaint,  the fourth complaint,  and consolidated
it with the other remaining complaint and set a hearing.

Commencing  July 19, 1999, a hearing was held on Phase I of the SDG&E  complaint
issues  regarding  whether  SDG&E has the right to challenge  the rates  charged
under the power sales  agreement under the Federal Power Act ("FPA") Section 206
"just and  reasonable  standard",  or whether SDG&E has waived this right and is
limited to challenging the rates under the tougher Section 206 "public  interest
standard".  On  September  14,  1999,  the  Administrative  Law Judge issued his
initial decision (subject to review by FERC on exceptions or on its own motion),
holding that the standard of review to be applied in Phase II of the  proceeding
is the "public interest" standard.  The Phase II hearing regarding whether,  and
to what extent, the Company's power sale agreement rates are unlawful, excessive
and/or contrary to the public interest is scheduled for June 2000.



                                       25
<PAGE>
The Company  estimates that the potential refund amount, if the relief sought in
the third and  fourth  complaints  is  granted,  could be up to as much as $20.3
million plus accrued  interest  through the refund  date.  However,  the precise
nature of the claim has not yet been presented by SDG&E, and the final amount of
the  claim,  based on the  evidence,  could turn out  different  from the claims
presented in the  complaints.  The Company  continues to firmly believe that the
remaining two complaints are without merit and intends to vigorously  defend its
position. The Company cannot predict the ultimate outcome of this matter.

In addition,  the Company  currently  estimates  that the net revenue  reduction
resulting  from the loss of SDG&E  contract  that  expires in April 2001 will be
approximately $20 million annually.

Kirtland Air Force Base ("KAFB") Contract

As previously  reported,  the Company was informed that the Department of Energy
("DOE") had entered into an  intra-agency  agreement with the Western Area Power
Administration  ("Western")  on behalf  of KAFB,  one of the  Company's  largest
retail electric  customers,  under the terms of which Western will competitively
procure power for KAFB. In May 1999, the Company  received a request for network
transmission  service from Western to facilitate the delivery of wholesale power
to KAFB  over  the  Company's  transmission  system.  (See  PART  I,  ITEM 2. --
"MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS  -- OTHER  ISSUES  FACING  THE  COMPANY  --  Kirtland  Air Force Base
("KAFB")  Contract" in the  quarterly  report on Form 10-Q for the quarter ended
March 31, 1999.)

The Company denied Western's request,  by letter dated June 30, 1999, citing the
fact that KAFB is and will continue to be a retail  customer until the effective
date  KAFB can  elect  customer  choice  service  under  the  provisions  of the
Restructuring  Act of 1999 (the effective  date for customer  choice for KAFB is
January 1, 2002,  unless  extended by the PRC).  The Company also cited  several
provisions  of  Federal  law that  prohibit  the  provision  of such  service to
Western.  On October 4, 1999,  Western  filed a petition at the  Federal  Energy
Regulatory  Commission ("FERC") requesting the FERC to consider, on an expedited
basis,  ordering the Company to provide network  transmission service to Western
under the Company's Open Access Transmission Tariff on behalf of DOE and several
other entities located on KAFB. The Company responded to the Western petition on
October  25,  1999,  and intends to litigate  this  matter  vigorously.  The net
revenue  reduction  to the  Company  if DOE  replaces  the  Company as the power
supplier to KAFB is estimated to be approximately $7.0 million annually.



                                       26

In a  separate  but  related  proceeding,  the  Company  and the  United  States
Executive  Agencies  on behalf of KAFB are  involved  in a PRC case  regarding a
dispute  over the terms  under  which  KAFB has taken  retail  service  from the
Company.  Among  the  disputed  issues in this  case are the  interpretation  of
language in a retail rate  schedule  pertaining to the  continuation  of service
after expiration of the Company's electric service agreement for service to KAFB
and an issue related to the proper scope of the case under the New Mexico Public
Utility Act.

The  Company  is  currently  unable to  predict  the  ultimate  outcome of these
matters.

New Royalty Claim

On  September  23,  1999,  a class  action  lawsuit,  on behalf of  natural  gas
producers,  royalty  owners and  others,  was filed in state  district  court in
Stevens County,  Kansas against the Company and its  subsidiaries,  Sunterra Gas
Gathering  Company and  Sunterra Gas  Processing  Company  (collectively  called
"Company"),  as well as  numerous  other  unrelated  parties in the  natural gas
industry,  alleging  that gas  producers  have been  underpaid  royalties due to
mismeasurement  of gas on privately  owned lands.  The suit also  purports to be
brought on behalf of state taxing  authorities,  although no  representative  of
that  class  is  designated.  The  complaint  alleges  that  the  mismeasurement
practices  alleged  breached   contracts  between   plaintiffs  and  defendants,
constituted negligent or intentional misrepresentation,  conversion, negligence,
breach of fiduciary duty and violations of Kansas  statutory laws. The complaint
also alleges a civil  conspiracy  among  defendants to misrepresent  and mislead
plaintiffs.   The  complaint  also  alleges  that  the  defendants  fraudulently
concealed the mismeasurement  practices alleged in the complaint from plaintiffs
and seeks to suspend the  applicable  statute of limitations in order to recover
damages for the period from 1974 to the present.

The Company  will  vigorously  defend  against  this  lawsuit  and, at this very
preliminary  stage,  is unable to predict the ultimate  outcome or the potential
liability, if any.

City of Gallup ("Gallup") Complaint

As  previously  reported,  in  1998,  Gallup,  Gallup  Joint  Utilities  and the
Pittsburg & Midway Coal Mining Co.  ("Pitt-Midway")  filed a joint complaint and
petition  ("Complaint")  with the NMPUC  (predecessor of the PRC). The Complaint
sought  an  interim   declaratory  order  stating,   among  other  things,  that
Pitt-Midway  is no  longer  an  obligated  customer  of the  Company,  Gallup is
entitled to serve  Pitt-Midway  and the Company  must wheel power  purchased  by
Gallup from other suppliers over the Company's transmission system. In September
1998,  the NMPUC  issued an order  without  conducting  a hearing,  granting the
requests  sought in the  Complaint.  The  Company  strongly  disagreed  with the
NMPUC's  decision and filed a motion with the New Mexico Supreme Court ("Supreme
Court") in  September  1998,  requesting  an  emergency  stay of the NMPUC order
pending its appeal of the order. (See  "MANAGEMENT'S  DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- OTHER ISSUES FACING THE COMPANY
- -- NMPUC REGULATORY ISSUES -- City of Gallup  ("Gallup")  Complaint" in the 1998
Form 10-K.)

                                       27
<PAGE>


On August 16, 1999,  oral arguments on the Company's  appeal were heard,  and on
October 13, 1999, the Supreme Court issued an order,  annulling and vacating the
NMPUC final order on remand  regarding  the Gallup  Complaint,  stating that the
NMPUC lacked the statutory authority to issue that order, because the New Mexico
Public  Utility Act did not authorize  Gallup to seek a wheeling  order from the
NMPUC. The Company has filed testimony regarding certain aspects of its petition
for declaratory order at the FERC,  requesting a determination as to whether the
Company's  agreement  with Gallup  requires (i) the Company to deliver energy to
Gallup at the Company's  Yah-Ta-Hey station and (ii) the Company to wheel energy
for Gallup. Hearings are scheduled in February 2000.

Nuclear Decommissioning Trust

As previously  reported,  in 1998,  the Company and the trustee of the Company's
master  decommissioning  trust filed a civil complaint and an amended complaint,
respectively,    against    several    companies   and   individuals   for   the
under-performance  of a corporate  owned life  insurance  program.  The program,
which was approved by the NMPUC and set up in a trust in 1987,  was used to fund
a portion of the Company's  nuclear  decommissioning  obligations  for its 10.2%
interest in PVNGS.  In January 1999, the life insurance  program was terminated,
and the life  insurance  policies were  surrendered by the trust in exchange for
the cash surrender value of the policies.  In the lawsuit,  the Company asserted
various tort,  contract and equity  theories  against the  defendants,  seeking,
among other  things,  an amount  sufficient  to  compensate  for the harm to the
Company  caused by the  defendants'  conduct.  A  defendant  counterclaimed  for
indemnity based on its engagement contract with the Company, claiming that if it
had injured the  trustee,  then the Company  must pay the  damages.  The Company
denied  liability under the counterclaim  and set forth numerous  defenses.  The
case is proceeding in State District Court in Santa Fe County.  The  defendants'
motions to dismiss were denied and the  Company's  motions to further  amend the
complaint to assert claims against two additional defendants,  a law firm and an
accounting  firm, were granted.  (See PART II, ITEM 1. -- "LEGAL  PROCEEDINGS --
Nuclear  Decommissioning  Trust" in the Company's  quarterly report on Form 10-Q
for the quarter ended June 30, 1999.)

On August 13,  1999,  the Company  appealed one of the trial  court's  decisions
regarding  pretrial  discovery  to the New Mexico  Court of Appeals.  While this
decision is on appeal,  all pretrial  discovery is being stayed.  The Company is
currently unable to predict the ultimate outcome or amount of recovery, if any.

ITEM 5.  OTHER INFORMATION

Clean Air Act

As previously reported,  the Clean Air Act Amendments of 1990 (the "Act") impose
stringent limits on emissions of sulfur dioxide and nitrogen from  fossil-fueled
electric generating plants. The Act is intended to reduce air contamination from
every sizable  source of air pollution in the nation.  The Act  established  the
Grand Canyon Visibility Transport Commission  ("Commission") and charged it with
assessing  adverse  impacts on visibility at the Grand  Canyon.  The  Commission
broadened its scope to assess  visibility  impairment in mandatory Class I areas
(parks and  wilderness  areas) located in the Colorado  Plateau.  The Commission
submitted  its  findings and  recommendations  to the  Environmental  Protection
Agency ("EPA") in June 1996.  See PART I, ITEM 1. -- "BUSINESS --  ENVIRONMENTAL
FACTORS" in the 1998 Form 10-K.

On July 1, 1999, the final regional haze regulations were published. The purpose
of  the  regional  haze  regulations  is to  address  regional  haze  visibility
impairment in the 156 Class I areas in the nation.  The final rule calls for all
states to  establish  goals and  emission  reduction  strategies  for  improving
visibility in all of the Class I areas. The rule contains specific provisions to
allow the western states to implement the  Commission's  recommendations  within
the framework of Section 309 of the rule.

Arizona  Public  Service  Company  ("APS"),  as the operating  agent of the Four
Corners  Power Plant ("Four  Corners"),  previously  filed a petition for review
alleging EPA improperly  classified Four Corners Unit 4 with respect to nitrogen
oxides  emission  limitations.  In October 1999, EPA issued a direct final rule,
which classified Four Corners Unit 4 as APS proposed.  Depending on the comments
filed by  other  parties,  if any,  the  rules  may be  become  final as soon as
December 1999. APS does not currently expect this rule to have a material impact
on the Four Corners operations.

In  a  related   matter,   in  September   1999,  the  EPA  proposed  a  Federal
Implementation  Plan  ("FIP") to set air  quality  standards  at  certain  power
plants,  including  Four  Corners.  The comment  period on this proposal ends in
November  1999.  The FIP is  similar to current  New Mexico  regulation  of Four
Corners with minor modifications.  APS does not currently expect the FIP to have
a material impact on the Four Corners operations.

Certain Assets of Plains Electric Generation and Transmission Cooperative,  Inc.
("Plains")

As previously  reported,  the Company and Tri-State  Generation and Transmission
Association,  Inc. ("Tri-State") submitted a binding joint offer in 1998 for the
acquisition of the assets of Plains, and Plains  subsequently  announced that it
would be entering  into  exclusive  negotiations  with the Company and Tri-State
regarding  the joint  proposal.  Plains  entered  into a merger  agreement  with
Tri-State,  with Tri-State  being the surviving  entity.  Tri-State  would then,
under the terms of an asset sale agreement with the Company, sell certain assets
to the  Company  consisting  primarily  of  transmission  assets  and the Plains


                                       29
<PAGE>

headquarters building in Albuquerque.  In addition, the Company agreed to become
the power supplier of approximately 50 MW to one of Plains' member cooperatives.
Plains,  Tri-State and the Company have filed for regulatory  approvals from the
PRC and the Federal Energy Regulatory  Commission.  (See ITEM 2. --"MANAGEMENT'S
DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF  OPERATIONS  --
ASSETS  ACQUISTIONS"  in the  Company's  quarterly  report  on Form 10-Q for the
quarter ended June 30, 1999.)

In the pending PRC case,  a  settlement  stipulation  was entered into among the
Company,  Tri-State, Plains and the PRC Staff to resolve the issues in the case,
to  permit  the  merger  to take  place  and to  allow  Tri-State  to  sell  the
above-referenced  assets to the Company.  None of the other  intervenors  in the
case objected to the settlement  stipulation.  The principal  disputed issue had
been the scope of the PRC's  jurisdiction over Tri-State after the completion of
the merger;  Tri-State argued that the PRC should have very limited jurisdiction
while  the  PRC  Staff  argued  for  substantially  broader  jurisdiction.   The
settlement stipulation effected a compromise in which there would be limited PRC
rate regulation of Tri-State after the merger.  A hearing on the stipulation was
held commencing on November 2, 1999 before a PRC hearing  examiner.  The Company
cannot  predict the outcome of the case or when a decision will be issued by the
PRC.

The Company and Tri-State entered into an asset sale agreement,  dated September
9, 1999,  pursuant to which  Tri-State  has agreed to sell the  above-referenced
assets to the  Company.  The  purchase  price to be paid by the Company is $13.2
million,  subject to adjustment at the time of the closing of the purchase.  The
asset sale agreement contains standard covenants and conditions for this type of
agreement.

  Section 1. Meetings.  The Annual Meeting of Stockholders shall be held on such
date and at such time and  place as may be fixed  from time to time by the Board
of  Directors of the Company  pursuant to a resolution  adopted by a majority of
the members of the Board then in office,  for the election of directors  and the

Special  meetings  may be called by a majority  of the Board of  Directors,  the
Executive Committee, the Chairman of the Board or the President.

  Section  2.  Place  of  Meetings.   The  annual  or  any  special  meeting  of
stockholders shall be held at the principal office of the Company in the City of
Albuquerque,  Bernalillo  County,  State of New Mexico,  or at such other places

such meeting.

  Section 3. Notice.  Written notice of any meeting  stating the time and place,
and if a special  meeting,  the purpose or purposes  of such  meeting,  shall be
mailed to each  stockholder  of record  entitled to vote at such  meeting at the
address of such  stockholders as the same appears on the stock transfer books of
the Company,  except as otherwise  provided by law. In the event of the transfer
of a  stockholder's  stock after mailing of such notice and prior to the holding
of the  meeting,  it shall not be necessary to mail notice of the meeting to any
transferee.  All notices of any special  stockholder meeting shall be mailed not
less than forty (40) days before the date of the meeting; however, notice of any
such  special  meeting  called  by a  majority  of the Board of  Directors,  the
Executive Committee,  the Chairman of the Board or the President,  and notice of
any  annual  meeting,  shall be mailed not less than ten (10) days  before  such
meeting of stockholders.


<PAGE>


  Section 4.  Quorum.  At any meeting of the  stockholders,  except as otherwise
provided  by law,  it shall be  necessary  that the holders of a majority of the
issued and  outstanding  shares of the  capital  stock  entitled to vote at such
meeting  shall be  represented  in person or by proxy to constitute a quorum for
the transaction of business.

  Section 5. Adjournment. Whenever at any meeting of the stockholders, notice of
which shall have been duly given, a quorum shall not be present, or whenever for
any  reason  it  may  be  deemed  desirable,  a  majority  in  interest  of  the
stockholders  present in person or by proxy may adjourn the meeting from time to
time to any future day, without notice other than by announcement at the meeting
or adjournment  thereof.  At any such adjourned meeting at which quorum shall be
present,  any business may be transacted which might have been transacted at the
meeting on the date originally fixed.

  Section 6. Organization.  The Chairman, or in the absence of the Chairman, the
President,  or in the absence of both, a Vice  President  shall call meetings of
the  stockholders  to order and  shall act as  Chairman  of such  meetings.  The
stockholders  may appoint any stockholder or the proxy of any stockholder to act
as Chairman of any meeting of the  stockholders  in the absence of the Chairman,
President  and  Vice  Presidents.  The  Secretary,  or in  the  absence  of  the
Secretary, an Assistant Secretary, shall act as Secretary at all meetings of the
stockholders,  but in the absence of the Secretary and Assistant  Secretaries at
any meeting of the stockholders the presiding  officer may appoint any person to
act as Secretary of such meeting.

  Section 7. Inspectors.  At each meeting of the stockholders at which a vote by
ballot is taken,  the polls shall be opened and closed,  the proxies and ballots
shall be received  and be taken in charge,  and the  validity of proxies and the
acceptance or rejection of votes shall be decided by two  inspectors.  No person
who is a candidate  for the office of  director  shall act as  Inspector  of any
election  for  directors.  Such  inspectors  shall be  appointed by the Board of
Directors before the meeting,  or, if no such appointment  shall have been made,
then by the  presiding  officer  of the  meeting.  If for any  reason any of the
inspectors  previously  appointed shall fail to attend or refuse or be unable to
serve,  inspectors in place of any so failing to attend or refusing or unable to
serve shall be appointed in like manner.

  Section 8. Voting. At each meeting of stockholders every stockholder,  whether
resident or  nonresident,  shall be entitled to one vote for each share of stock
standing in the name of the  stockholder on the books of the Company on the date
on which stockholders  entitled to vote are determined.  Such stockholder may be
represented  and  vote by a proxy  or  proxies  appointed  by an  instrument  in
writing;  in the event that such  instrument in writing  shall  designate two or
more  persons to act as  proxies,  a  majority  of such  persons  present at the
meeting,  or if only one shall be  present,  then  that one  shall  have and may
exercise all of the powers conferred by such written  instrument upon all of the
persons so designated,  unless the instrument shall otherwise provide.  No proxy
shall be voted at any meeting or  adjournment  thereof other than that for which
the proxy is given.

  In all elections for directors, voting shall be by written ballot.

  The Board of Directors may fix a date in advance not exceeding fifty (50) days
preceding  the date of any  meeting  of  stockholders  as a record  date for the
determination  of  stockholders  entitled  to  notice of and to vote at any such
meeting, and in such case only stockholders of record on the date so fixed shall
be entitled to notice of and to vote at such meeting.

need be a resident of the State of New Mexico.  The  directors  shall be nine in
number and shall be elected in classes in the manner  provided in Article  Fifth
of the Articles of Incorporation as amended.

  Section 2. Chairman of the Board of Directors.  The Chairman  shall be elected

the Board of  Directors  shall,  by a majority  vote of the Board of  Directors,

purposes.  The Chairman shall preside at all meetings of the stockholders and of
the Board of Directors unless the Chairman shall be absent or incapacitated. The
Chairman of the Board, subject to the authority of the Board, shall generally do
and  perform all acts  incident  to the office of the  Chairman of the Board and
which are authorized or required by law.

  Section 3.  Vacancies.  Any  vacancies  occurring on the Board of Directors by
death, resignation, or otherwise shall be filled by a majority of Directors then
remaining in office.

  Section 4. Meetings.  The meetings of the Board of Directors  shall be held at

Company of New Mexico Employee  Retention Plan ("Employee  Retention  Plan"), or
any other similar  severance,  retention or change in control plan or agreement.
This Plan shall hereafter include three forms of severance benefits: (a) Regular

addressed  to the  Committee;  (b)  received  within  sixty  (60) days after the
receipt by the claimant of the  Committee's  initial written denial of benefits;
and (c) failure to perfect an appeal within the sixty (60) day period shall make
the decision conclusive.

         11.2. If the claimant should appeal to the Committee, he or she, or his
or her duly authorized representative,  must do so in writing and may submit, in
writing,  whatever  issues and comments he or she, or his or her duly authorized
representative, feels are pertinent. The claimant, or his or her duly authorized
representative,  may review pertinent Plan documents. The Committee shall render
a written  decision  on the  question of the  benefits  payable or the claim for
benefit,  setting  forth the  specific  reasons  for its  decision,  including a
reference to the Plan's provisions,  within sixty (60) days after receipt of the
request for  reconsideration,  unless special  circumstances (such as a hearing)
would  make the  rendering  of a  decision  within  the  sixty  (60)  day  limit
infeasible,  but in no event shall the Committee render a decision  respecting a
denial for a claim for benefits  later than one hundred  twenty (120) days after
its receipt of a request for a review.

         Agreement shall become effective upon the later of the following dates:
         (a) the date upon which the FERC  accepts  for filing  this  Agreement;
         provided  that, if the FERC orders a hearing to determine  whether this
         Agreement  is just and  reasonable,  this  Agreement  shall not  become
         effective  until the date when an order,  no longer subject to judicial

         in support of the filing.

                  4.3 Following (a) an order by the FERC or any other regulatory
         agency having jurisdiction, or (b) a letter or other communication from
         the RUS,  the  Participants  shall each review  such  order,  letter or
         communication  to  determine  if the  FERC,  RUS or any  agency  having

         with regard to this Agreement;  or has conditioned its approval of this
         Agreement upon changes or  modifications  to a condition or conditions,
         deletion of a condition or  conditions or imposition of a new condition
         or  conditions.   The  Participant  receiving  such  order,  letter  or
         communication  shall promptly  provide a copy of such order,  letter or
         communication to the other  Participants.  Within fifteen (15) business

         in writing their  acceptance or rejection of this Agreement  based upon
         any changes, modifications, deletions or new conditions required by the
         FERC, RUS or any agency having jurisdiction. A failure to notify within
         said fifteen (15) day period shall be the  equivalent to a notification
         of acceptance.  If any Participant  rejects this Agreement  because the

         Agreement and they shall attempt,  in good faith,  to  renegotiate  the
         terms  and  conditions  of this  Agreement  to  resolve  such  changed,
         modified,   deleted  or  new  condition  to  the  satisfaction  of  the
         Participants  within one  hundred  twenty  (120) days after the date of
         such order,  letter or communication and thereafter to obtain requisite
         regulatory approval of such renegotiated agreement.

         capital   expenditures   necessitated  by  an  Operating  Emergency  or
         otherwise deemed  justifiable by the Operating Agent, shall be included
         in  the  annual  capital   expenditures  budget.  The  Engineering  and
         Operating Committee may authorize Capital  Improvements not included in
         the annual capital  expenditures  budget;  provided,  that such Capital
         Improvements  shall not exceed the sum of five hundred thousand dollars
         ($500,000) for each such Capital Improvement, unless also authorized by
         the Coordination Committee.

                  7.5 The  Operating  Agent shall submit to the  Participants  a
         forecast of cash requirements by months for Capital Improvements.  Said
         forecast  will be  submitted  on a  yearly  basis  after  final  budget
         approvals  have been made. A revised  forecast  shall be submitted when
         the capital expenditures budget is revised, or when significant changes
         in monthly expenditures from those previously forecast are anticipated.
         The Operating Agent shall be authorized to make additional expenditures
         related  to  Capital   Improvements;   provided,   however,  that  such
         additional  expenditures for Capital  Improvements shall not exceed the
         sum of one  hundred  thousand  dollars  ($100,000)  or cause  the total
         expenditure  limit contained in the capital  expenditures  budget to be
         exceeded,  unless also  authorized  by the  Engineering  and  Operating
         Committee,  or by the Coordination  Committee if the total  expenditure
         for such Capital  Improvement  exceeds five  hundred  thousand  dollars
         ($500,000).

                  7.6  In  the  event  of  the  removal  or  retirement  of  any
         facilities  comprising  part  of the San  Juan  Project,  any  proceeds
         realized from the salvage of such  facilities  shall be  distributed to
         the Participants in accordance with their Participation Shares therein,
         or shall be applied on account of the Participant's  obligations to pay
         for Capital Improvements replacing facilities removed or retired. Units
         of Property  retired from service shall be disposed of by the Operating
         Agent on the best available terms as soon as practicable.

                  7.7 Each Participant shall have the right, at its own expense,
         to  add   facilities  to  the  Switchyard   Facilities,   provided  the
         Engineering  and  Operating  Committee  approves  the  design  of  such
         additional  facilities and determines that space is available therefor,
         and that such committee also determines that such additional facilities
         will not (i)  infringe  upon the rights of another  Participant  in the
         Switchyard   Facilities,   (ii)  unreasonably   interfere  with  future
         expansion plans at the San Juan Project, (iii) impair or interfere with
         the contractual rights of another  Participant,  or (iv) jeopardize the
         reliability  of  another  Participant's  system.  The  Engineering  and
         Operating  Committee  shall have  authority to impose  conditions  on a
         Participant  allowed to make such  additions  in order to  protect  the
         other  Participants.  Such facilities  shall be and remain the sole and
         exclusive property of the Participant  installing same until and unless
         the  Coordination   Committee   determines  that  such  facilities  are
         necessary  and  beneficial  for  operation of the San Juan Project as a
         whole.  In the event of such  determination,  the  facilities  shall be
         acquired  as a part of the San Juan  Project  by the  Participants  and
         compensation   shall  be  paid  to  the  selling   Participant  by  the
         Participants  acquiring  such  interest  based on the net book value of
         such facilities.

                  7.8 Each Participant shall have the right, at its own expense,
         to add protective relay or communication equipment to facilities solely
         owned by it, if the  Participant  determines  the  protective  relay or
         communication  equipment is needed for the  protection  of its electric
         system,  provided the Engineering and Operating  Committee approves the
         design  of such  additional  equipment  and  determines  that  space is
         available  therefor,  and that such committee also determines that such
         additional  facilities will not (i) infringe upon the rights of another
         Participant in the facilities,  (ii) unreasonably interfere with future
         expansion plans at the San Juan Project, (iii) impair or interfere with
         the contractual rights of another  Participant,  or (iv) jeopardize the
         reliability of another Participant's system.

                  7.9  Transportation  and  motorized  equipment  which is to be
         utilized by the Operating  Agent for Operating Work may be purchased or
         leased by the Operating Agent upon receipt of the approval  referred to
         in  Section  19.3.4.  Ownership  of such  purchased  equipment  and the
         purchase  price  thereof  shall be  allocated  between  and paid by the
         Participants in proportion to the percentages established in Section 6.
         Lease  payments made by the Operating  Agent for such leased  equipment
         shall be apportioned between and paid by the Participants in accordance
         with  Section   22.1.   No  allowance  to  the   Operating   Agent  for
         administrative  and  general  expense  shall be included in or added to
         such lease payments for transportation  and motorized  equipment which,
         in lieu of acquiring such  equipment by purchase,  has been leased on a
         long-term basis.

                  7.10 Upon  retirement of leased  transportation  and motorized
         equipment  utilized  for  Operating  Work,  an amount,  which  shall be
         treated as a charge (or credit), shall be determined by multiplying the
         difference between the salvage value and the unamortized  balance owing
         to the leasing  company for each piece of such equipment by a fraction,
         the  numerator  of which is the sum of the monthly  lease  payments for
         such equipment  charged to Operating Work and the  denominator of which
         is the sum of all monthly lease  payments  made by the Operating  Agent
         for such equipment.  Such charge or credit shall be allocated among the
         Participants in accordance with the applicable percentages set forth in
         Section 22.

                  7.11  Administrative  and  general  expenses  which  have been
         incurred by the  Operating  Agent which are  applicable  to  authorized
         Capital  Improvements,  shall be applied monthly to construction  costs
         incurred  during the preceding  month.  A rate will be developed by the
         Operating  Agent  every  three  (3)  years  in  conjunction   with  the
         administrative   and  general  ("A&G")  expenses  study  referenced  in
         Attachment A to Exhibit VI. The current methodology for calculating the
         A&G  Ratio  for  Capital  Improvements  is set  forth  in  Exhibit  VI,
         Attachment  E. If any  Participant  believes  that the  method  used in
         determining  the A&G  Ratio  for  Capital  Improvements  results  in an
         unreasonable  burden on such  Participant(s),  such  Participant(s) may
         request that said method used in determining said ratio be submitted to
         the Auditing Committee for review in accordance with the procedures set
         out in Sections 22.6.1 through 22.6.4.

                  7.12  Excluded  from the charges in Section  7.11 are expenses
         incurred under Section 36.2.

         interests in the San Juan Project, water rights, lands, land rights and
         improvements  thereon  as  tenants  in  common,  and agree  that  their
         interests  therein  shall be held in such  tenancy  in  common  for the
         duration  of the  term  of this  Agreement,  including  any  extensions
         thereof.  While  this  Agreement,  including  any  extensions  thereof,
         remains in force and effect, each Participant agrees as follows:

                           8.1.1 That it hereby  waives  the right to  partition
                  the San Juan Project,  water rights, lands, land rights or the
                  improvements  built thereon  (whether by partitionment in kind
                  or by sale and division of the proceeds thereof), and

                           8.1.2 That it will not resort to any action at law or
                  in equity to  partition  (in either such  manner) the San Juan
                  Project,  water rights, lands, land rights or the improvements
                  built thereon and waives the benefits of all laws that may now
                  or hereafter authorize such partition.

                  11.1 The purpose of this Section 11 is to set forth the manner
         in which all existing or future rights of first refusal,  pertaining to
         the transfer of interests in the San Juan Project,  shall be exercised.
         Except as provided in Section 10, PNM has a right of first refusal with

         with  respect to PNM's  proposed  transfer  of an interest in Unit 1 or

         first  refusal  shall  be as  provided  in other  instruments  to which
         Participants are parties. Nothing in this Section 11 shall be construed
         to limit or expand the rights of first refusal of any Participant.

                  11.2 Except as provided  in Section 10,  should a  Participant
         desire to assign, transfer, convey or otherwise dispose of (hereinafter
         collectively  referred to as "Assign") its rights, titles and interests
         in the San Juan Project, or its rights, titles and interests in, to and
         under the Project  Agreements,  or its rights,  titles and interests in
         the water rights, lands, land rights or the improvements thereon or any
         part thereof or interest therein (hereinafter  referred to as "Transfer
         Interest"), to any person, company,  corporation or governmental agency
         (hereinafter  referred to as "Outside Party"), the Participant desiring
         to Assign shall first make an offer to sell the Transfer  Interest to a
         Participant(s)  having a right of first  refusal,  on the  basis of the
         applicable  amount  as set out in  either  Section  11.2.1  or  Section
         11.2.2:

                           11.2.1 Where the Outside  Party  proposes to purchase
                  for a specified monetary amount, from the Participant desiring
                  to Assign,  an interest only in the San Juan Project and/or in
                  contract  rights,   water  rights,   lands,  land  rights  and
                  improvements  associated  therewith,  the amount of (i) a bona
                  fide written  offer from an Outside  Party ready,  willing and
                  able (subject to obtaining any required regulatory  approvals)
                  to purchase  the  Transfer  Interest;  or, in the absence of a
                  bona fide written  offer,  (ii) a purchase  price set out in a
                  bona fide purchase and sale agreement  between the Participant
                  desiring  to Assign and an Outside  Party  ready,  willing and

                           11.2.2 Where the Outside  Party  proposes to purchase
                  from the  Participant  desiring  to  Assign,  (i) as part of a
                  non-monetary  offer  (such as in the case of an asset swap) or
                  (ii) when a segregated value for the Transfer  Interest is not
                  available  (such as in the case of a bundled or packaged  sale
                  of  assets),  or (iii)  where the  Outside  Party  proposes to
                  purchase an interest not only in the San Juan  Project  and/or
                  in  contract  rights,  water  rights,  lands,  land rights and
                  improvements associated therewith,  but also in other property
                  of the Participant  desiring to Assign,  the fair market value
                  of the  Transfer  Interest.  As used  herein,  the term  "fair
                  market  value"  means the amount of money  which a  purchaser,
                  willing but not obligated to buy the property,  will pay to an
                  owner,  willing  but not  obligated  to sell it,  taking  into
                  consideration  all of the uses to which the Transfer  Interest
                  is adapted and might in reason be applied.

                  11.3 At least three (3) months prior to its  intended  date to
         Assign,  and  after  its  receipt  of a bona  fide  written  offer,  or
         execution  of a bona  fide  purchase  and sale  agreement,  of the type
         described  in Section  11.2,  the  Participant  desiring  to Assign its
         Transfer  Interest shall serve written notice of its intention to do so
         upon the Participant(s)  having a right of first refusal, in accordance
         with Section 42. Such notice  shall:  (i) have attached as an exhibit a
         copy of the bona  fide  offer of an  Outside  Party or of the bona fide
         purchase  and  sale  agreement   between  the  Outside  Party  and  the
         Participant  desiring to Assign (an  "Outside  Offer");  and (ii) shall
         contain a statement of the approximate proposed date to Assign.

                  11.4 The  Participant(s)  having  the  right of first  refusal
         shall  signify  its  (their)  desire to  purchase  the entire  Transfer
         Interest,  or not purchase  the entire  Transfer  Interest,  by serving
         written notice of its (their)  intention upon the Participant  desiring
         to Assign  pursuant  to  Section  42 within  sixty (60) days after such
         service  pursuant to Section 11.3 of the written notice of intention to
         Assign.  Failure by a Participant to serve notice as provided hereunder
         within the time period  specified  shall be  conclusively  deemed to be
         notice of its intention not to purchase the Transfer Interest.

                  11.5 When intention to purchase the entire  Transfer  Interest
         has  been   indicated   by  notices   duly  given   hereunder   by  the
         Participant(s) desiring to purchase the Transfer Interest, the affected
         Participants shall thereby incur the following obligations:

                           11.5.1  The  Participant  desiring  to  Assign  and a
                  Participant  desiring to purchase the Transfer  Interest shall
                  be  obligated  to proceed in good faith and with  diligence to
                  obtain all required authorizations and approvals to Assign;

                           11.5.2 The  Participant  desiring to Assign  shall be
                  obligated  to obtain the  release  of any liens  imposed by or
                  through  it upon  any  part of the  Transfer  Interest  and to
                  Assign the Transfer Interest at the earliest  practicable date
                  thereafter; and

                           11.5.3  A   Participant   desiring  to  purchase  the
                  Transfer  Interest shall be obligated to perform all terms and
                  conditions  required  of it to  complete  the  purchase of the
                  Transfer Interest.


                                       35
<PAGE>

         The purchase of the Transfer Interest shall be fully consummated within
         six (6) months following the date upon which all notices required to be
         given  under  this  Section  11  have  been  duly  served,  unless  the
         Participant is then  diligently  pursuing  applications  to appropriate
         regulatory  bodies (if any) for required  authorizations to effect such
         assignment or is then diligently  prosecuting or defending appeals from
         orders  entered  or  authorizations  issued  in  connection  with  such
         applications.

                  11.6 If the intention to purchase the entire Transfer Interest
         has not been  indicated  by  notices  given  within  the  time  periods
         specified in this Section 11 by a Participant  desiring to purchase the
         Transfer Interest,  the Participant desiring to Assign shall be free to
         Assign  all,  but not less than all,  of its  Transfer  Interest to the
         Outside  Party  that  made  the  Outside  Offer,  upon  the  terms  and
         conditions  set forth in the Outside Offer.  If such  assignment of the
         entire Transfer  Interest to the Outside Party is not completed  within
         three (3) years after the approximate proposed date to Assign specified
         in the notice given pursuant to Section 11.3, the Participant  desiring
         to Assign its  Transfer  Interest  must,  unless it is then  diligently
         pursuing its applications to appropriate regulatory bodies (if any) for
         required   authorizations  to  effect  such  assignment,   or  is  then
         diligently  prosecuting  or defending  appeals  from orders  entered or
         authorizations  issued  in  connection  with  such  applications,  give
         another  complete  new  right of first  refusal  to the  Participant(s)
         desiring to purchase  pursuant to the  provisions  of this  Section 11,
         before such Participant  shall be free to Assign a Transfer Interest to
         said Outside Party.

                  11.7 No assignment of a Transfer Interest,  whether to another
         Participant  or  to an  Outside  Party,  shall  relieve  the  assigning
         Participant  from  full  liability  and  financial  responsibility  for
         performance  after  any such  assignment:  (i) of all  obligations  and
         duties incurred by such Participant  prior to such assignment under the
         terms and  conditions  of the  Project  Agreements;  and/or (ii) of all
         obligations  and duties provided and imposed after such assignment upon
         such  assigning  Participant  under  the terms  and  conditions  of the
         Project  Agreements,  unless  and until  the  assignee  shall  agree in
         writing with the remaining  Participants  to assume the obligations and
         duties of a Participant hereunder; provided further, however, that such
         assignor shall not be relieved of any of its  obligations and duties by
         an assignment  under this Section 11, without the express prior written
         consent  of the  remaining  Participants,  which  consent  shall not be
         unreasonably withheld.

                  11.8 Any transferee,  successor or assignee,  or any party who
         may succeed to the Transfer Interest pursuant to this Section 11, shall
         specifically  agree in writing with the remaining  Participants  at the
         time of such transfer or assignment that it will not transfer or assign
         all or any  portion  of  the  Transfer  Interest  so  acquired  without
         complying with the terms and conditions of this Section 11.

                  11.9 The provisions of Section 11.8 shall not be applicable to
         any  assignment of a Transfer  Interest by one  Participant  to another
         Participant,  provided that payment in full of such Transfer  Interest,
         as defined in Section 11, has been made by the  Participant  who is the
         assignee thereof.

                  11.10 A  Participant  may,  for the purpose of  financing  its
         interest in pollution  control  systems and  facilities at the San Juan
         Project,  sell,  transfer or convey such interests  pursuant to the New
         Mexico Pollution Control Revenue Bond Act, and any such sale,  transfer
         or  conveyance  shall  not  be  deemed  as  an  assignment,   transfer,
         conveyance or other disposal within the meaning of this Section 11.

                   ENTITLEMENTS TO OUTPUT OF SAN JUAN PROJECT

         14.0     ENTITLEMENT TO CAPACITY AND ENERGY:

                  14.1 Subject to the provisions of Section 16, the Participants
         shall be entitled to the Net Effective  Generating  Capacity of each of
         Unit 1, Unit 2,  Unit 3 and Unit 4 in  proportion  to their  respective
         Participation  Shares.  Each Participant  shall be entitled to schedule
         its Energy up to the Available Operating Capacity.

                  14.2 The Operating  Agent shall keep the system  dispatcher of
         each Participant advised of the Available Operating Capacity.

                  14.3  When  a  Participant's  request  for  its  share  of the
         Available Operating Capacity necessitates the operation of a Unit, each
         Participant  shall  schedule for its account not less than its share of
         Minimum Net  Generation.  If,  however,  a Participant has scheduled an
         amount of Energy in excess of its share of the Minimum Net  Generation,
         the other  Participants  shall be  allowed  to reduce  their  scheduled
         Energy to an amount  that will  maintain  the Unit at the  Minimum  Net
         Generation level.

                  14.4 The delivery of Energy from the San Juan Project shall be
         scheduled by each  Participant in advance with the Operating  Agent and
         accounted for on the basis of integrated hourly actual generation,  all
         in accordance with any operating procedures which may be established or
         approved by the  Engineering  and Operating  Committee.  Such operating
         procedures shall provide for modifying such schedules to meet the needs
         of day-to-day and hour-by-hour  operation,  including  emergencies on a
         Participant's system.

                  14.5  The  Operating  Agent  shall,  to the  extent  possible,
         generate  Energy at the San Juan Project in accordance  with  schedules
         submitted by each  Participant,  as such  schedules may be revised from
         time to time, as long as such schedules do not jeopardize the operation
         of the San Juan Project.

                  14.6 The  Participants  shall  revise  their  schedules in the
         event of an Operating Emergency or other incident beyond the control of
         the Operating Agent to reflect the actual Energy available from the San
         Juan Project during the period of the Operating Emergency or incident.

                  14.7 The Energy  generated  at the San Juan  Project  shall be
         controlled within PNM's Control Area; provided, that such control shall
         not diminish the rights of any  Participant to receive its  entitlement
         of Energy from the San Juan Project.

         16.0     USE OF FACILITIES DURING CURTAILMENTS:

                  16.1 If the Net Effective  Generating Capacity of all Units is
         reduced because of factors  (including,  but not limited to,  equipment
         failures,  scheduled or unscheduled  outages,  fuel or fuel deliveries,
         water supply,  air quality  limitations)  which commonly  influence the
         total output of all Units, each  Participant's  entitlement to Capacity
         during such period shall be reduced in  proportion  to the  percentages
         specified in Section 6.2.6 during each hour of such curtailment  unless
         otherwise specified in a separate agreement.

                  16.2 If factors which  influence the operation of a Unit cause
         a curtailment  of that Unit,  then the capacity  entitlement  from that
         Unit for each  Participant  in that Unit shall be in  proportion to the
         Participant's Participation Share of that Unit.

                  16.3 If,  because of factors  which  influence  the  operation
         solely of Units 1 and 2, or solely of Units 3 and 4,  there  shall be a
         curtailment  of Units 1 and 2, or of Units 3 and 4, as the case may be,
         the curtailment  for each  Participant in Units 1 and 2, or Units 3 and
         4, shall be allocated in  proportion  to the  percentages  specified in
         Sections 6.2.4 and 6.2.5, respectively.

                  16.4 To the extent that a curtailment results from scarcity of
         resources and not from  mechanical or legal  limitations,  Participants
         may agree in writing to modify  their  schedules to allocate the use of
         such  resources  to such  Unit(s)  or to such times as to make the most
         efficient use thereof, consistent with Prudent Utility Practice, during
         the pendency of such  curtailment.  Notwithstanding  the  provisions of
         Section 23.2,  the  Operating  Agent shall,  during such  curtailments,
         account for coal inventory on a Participant by Participant  basis. Upon
         the  conclusion  of such  curtailment,  the  provisions of Section 23.2
         shall apply to any remaining coal inventory.

         manner and in the amounts as set forth in Section 6.2.7.

                  16.6 No Participant  shall exercise its rights relating to the
         San Juan Project so as to endanger or  unreasonably  interfere with the
         operation of the San Juan Project or the right of any other Participant
         to use its share of Capacity and Energy from the San Juan Project.

         Participation  Share of the Energy requirements to start up and operate
         each Unit, and such requirements  shall be provided by the Participants
         based  upon  the   Participant's   percentage  of  operating  costs  in
         accordance with Section 22.1.  Appropriate metering facilities shall be
         installed to assure  measurement of such Energy.  Such requirements for

                                 ADMINISTRATION

         18.0     COORDINATION COMMITTEE:

                  18.1  As  a  means  of  securing  effective   cooperation  and
         interchange of information  and of providing  consultation  on a prompt
         and orderly basis among the  Participants  in  connection  with various
         administrative and technical problems which may arise from time to time
         under  this  Agreement,  the  Coordination  Committee  shall  remain in
         existence  during  the  term of this  Agreement.  Except  as  otherwise
         expressly provided in this Agreement,  the Coordination Committee shall
         have no authority to modify any of the provisions of this Agreement.

                  18.2  The   Coordination   Committee   shall  consist  of  one
         representative  from each  Participant who shall be an officer or other
         duly   authorized   representative   of  a  Participant.   Any  of  the
         Participants  may  designate an alternate or  substitute  to act as its
         representative  on the  Coordination  Committee  in the  absence of the
         regular  representative  on  the  Coordination  Committee  or to act on
         specified  occasions  or  with  respect  to  specified  matters.   Each
         Participant shall notify the other Participants  promptly,  in writing,
         of the designation of its representative  and alternate  representative
         on the  Coordination  Committee and of any  subsequent  changes in such
         designations.

                  18.3 The  Coordination  Committee  shall  have  the  following
         functions and  responsibilities:

                           18.3.1   Provide   liaison   between  and  among  the
                  Participants.

                           18.3.2   Exercise   general   supervision   over  the
                  Engineering and Operating  Committee,  the Fuels Committee and
                  the Auditing Committee.

                           18.3.3 Consider and act upon all matters  referred to
                  the  Coordination  Committee by the  Engineering and Operating
                  Committee,  the Fuels  Committee  and the Auditing  Committee.

                  18.4 Any action or determination of the Coordination Committee
         shall require a vote of the  Participants  in accordance  with Sections
         18.4.1,  18.4.2  or  18.4.3.  A  Participant's  Coordination  Committee
         representative  shall be entitled to vote on all matters  except  those
         actions or  determinations  which relate  solely to a Unit or to common
         property in which such Participant does not have a Participation  Share
         or as provided in Section 35.4.1. If a Participant's  right to vote has
         been suspended pursuant to Section 35.4.1, the requisite majorities for
         actions or  determinations  specified  in Sections  18.4.1,  18.4.2 and
         18.4.3 shall be adjusted in  proportion  to the number of  Participants
         whose  right to vote  has not been  suspended.  An  example  of such an
         adjustment   is  provided  in  Exhibit   VIII,   attached   hereto  and
         incorporated  herein.   Maintenance  scheduling  and  operation  during
         periods of  curtailment  of the total San Juan  Project are not matters
         which relate solely to a Unit,  but are deemed to be matters  affecting
         all Units.

                           18.4.1  Except as  provided  in  Sections  18.4.2 and
                  18.4.3,  any  actions  or  determinations  brought  before the
                  Coordination Committee shall require the following vote:

                                    (a) More  than a  sixty-six  and two  thirds
                           percent  (66  2/3%)  majority  of  the  Participation

                           individual  Participants having a Participation Share
                           in a Unit or common  property  as  defined in Section
                           6.2.

                           18.4.2   Any   action   or   determination   of   the
                  Coordination Committee related to common property as set forth
                  in Section  6.2.6 and  involving an  expenditure  greater than
                  five million dollars  ($5,000,000) shall require the following

                                    (a) More than an  eighty-two  percent  (82%)
                           majority   of  the   Participation   Shares   of  the
                           Participants as defined in Section 6.2.6; and

                                    (b) A minimum  of  sixty-six  and two thirds
                           percent  (66  2/3%)  majority  of the  number  of the
                           individual   Participants.

                           18.4.3   Any   action   or   determination   of   the
                  Coordination  Committee  regarding  any  amendment of the Coal
                  Sales Agreement,  replacement of the Coal Sales Agreement with
                  a new agreement or any interim coal pricing  agreement related
                  to the Coal Sales  Agreement (or its successor)  shall require
                  the following vote:

                                    (a) More than an  eighty-two  percent  (82%)
                           majority   of  the   Participation   Shares   of  the
                           Participants as defined in Section 6.2.6; and

                                    (b) A minimum  of  sixty-six  and two thirds
                           percent   (66  2/3%)   majority   of  the  number  of
                           individual Participants.

                  18.5 The Coordination Committee shall keep written minutes and
         records  of all  meetings.  Any  action  or  determination  made by the
         Coordination  Committee  shall be reduced to writing  and shall  become
         effective  when  signed  by the  representatives  of  the  Participants
         entitled to vote thereon, representing a voting majority of the members
         of the Coordination  Committee,  as defined in Section 18.4;  provided,
         however,   in  the  event  of  an  Operating   Emergency,   actions  or
         determinations  may be made on the basis of oral agreements  among duly
         authorized  representatives of the respective  Participants entitled to
         vote thereon,  and such action or determination  subsequently  shall be
         reduced to writing.

                  18.6 Except for matters subject to the voting  requirements of
         Section 18.4.3, in the event the Coordination  Committee fails to reach
         agreement  on  any  matter,  which  such  committee  is  authorized  to
         determine, approve or otherwise act upon after a reasonable opportunity
         to do so, then the Operating Agent shall be authorized and obligated to
         take such  reasonable  and  prudent  action,  consistent  with  Prudent
         Utility  Practice,  as  is  necessary  to  the  successful  and  proper
         operation  and  maintenance  of  the  San  Juan  Project,  pending  the
         resolution,  by  arbitration  or  otherwise,  of any such  inability or
         failure to agree.

                  18.7 In the event the  Coordination  Committee  fails to reach
         agreement  on a matter  subject to the voting  requirements  of Section
         18.4.3,  then an impasse shall be deemed to exist and the  Participants
         which are  signatories to the Coal Sales Agreement then in effect shall
         have the obligation  and the  responsibility,  consistent  with Prudent
         Utility Practice, to maintain a supply of coal to the San Juan Project.

                  which  reduces  or may  reduce  the Net  Effective  Generating
                  Capacity.

                           19.3.3 Except for an Operating Emergency, as provided
                  in Section 29, designate a construction  agent responsible for

         entitled to vote on all matters except those actions or  determinations
         which  relate  solely to a Unit or to  common  property  in which  such
         Participant  does not have a  Participation  Share  or as  provided  in
         Section  35.4.1.  If a  Participant's  right to vote has been suspended

         periods of  curtailment  of the total San Juan  Project are not matters
         which relate solely to a Unit,  but are deemed to be matters  affecting
         all Units.

         written   minutes   and  records  of  all   meetings.   Any  action  or
         determination made by the Engineering and Operating  Committee shall be
         reduced  to  writing  and shall  become  effective  when  signed by the
         representatives   of  the   Participants   entitled  to  vote  thereon,
         representing a voting  majority of the members of the  Engineering  and
         Operating Committee, as defined in Section 19.4; provided,  however, in
         the event of an Operating  Emergency,  actions or determinations may be
         made  on  the  basis  of  oral   agreements   among   duly   authorized
         representatives  of  the  respective   Participants  entitled  to  vote
         thereon, and such action or determination subsequently shall be reduced

                  19.6 In the event that less than a  requisite  majority of the
         Engineering  and Operating  Committee is obtained,  the matter shall be
         referred to the Coordination Committee for decision upon the request of
         any Participant's Engineering and Operating Committee representative.

                  19.7 In the  event the  Engineering  and  Operating  Committee
         fails  to  reach  agreement  on any  matter  which  such  committee  is
         authorized  to  determine,  approve  or  otherwise  act  upon  after  a
         reasonable  opportunity  to do so,  then the  Operating  Agent shall be
         authorized and obligated to take such  reasonable  and prudent  action,
         consistent  with  Prudent  Utility  Practice,  as is  necessary  to the
         successful  and  proper  operation  and  maintenance  of the  San  Juan
         Project,  pending the resolution,  by arbitration or otherwise,  of any
         such inability or failure to agree.

                  20.1  As a  means  of  establishing  a  centralized  forum  to
         facilitate the timely and candid  consideration and discussion  between
         all Participants of policies and issues associated with the procurement
         of coal for the San Juan Project,  there is hereby  established a Fuels
         Committee,  which  shall  remain in  existence  during the term of this
         Agreement.  The  Participants  do not intend that the  operation of the
         Fuels    Committee    shall   affect   the    day-to-day    operational
         responsibilities  of the fuels  management  department of the Operating
         Agent,  except as otherwise  specifically  provided in this Section 20.
         The Fuels  Committee  shall  have no  authority  to  modify  any of the
         provisions of this Agreement.

                  20.2 The Fuels Committee  shall consist of one  representative

         to the other Participants,  designate an alternate or substitute to act
         as its  representative  on the Fuels  Committee  in the  absence of the
         regular  representative  on the Fuels  Committee or to act on specified
         occasions or with respect to specified matters.  Each Participant shall
         notify the other Participants promptly in writing of the designation of
         its  representative on the Fuels Committee and of any subsequent change
         in such designation.  The chairperson of the Fuels Committee shall be a
         representative  employed by a  Participant  that is a signatory  to the
         Coal Sales Agreement.  The Fuels Committee shall meet regularly, but in
         no event less than  semiannually.  Special  meetings shall be called by
         the chairperson if requested in writing by any three (3) Participants.

                  20.3 The Fuels  Committee  shall have the following  functions
         and responsibilities:

                  performed  shall  have made  suitable  arrangements  therefor,
                  including payment arrangements with the provider of the study.

                  20.4  The  following  special  procedures  shall  apply to all
         negotiations  or  discussions  with SJCC regarding  amendment,  interim
         pricing  agreements,  termination  or  succession  of  the  Coal  Sales
         Agreement, or with any other coal supplier or potential supplier.

                           20.4.1 Each  Participant  which is a signatory to the
                  Coal Sales  Agreement  shall be  entitled to have at least two
                  (2)  representatives  present  at  any  such  negotiations  or
                  discussions.  Participants  not  signatories to the Coal Sales
                  Agreement  or its  successors  (for  purposes of this  Section
                  20.4.1,   the   "Remaining   Participants")   shall  have  the
                  collective  right to have two (2)  representatives  present at

                  Participants  exceed two (2). Any dispute  among the Remaining
                  Participants  regarding the naming of representatives shall be
                  subject  to  resolution  pursuant  to Section 37 and shall not
                  restrict the rights of any other  representatives to engage in
                  any ongoing negotiations or discussions. Representatives shall
                  be  designated  in  writing  by  the  Participants  which  are
                  signatories   to  the  Coal  Sales   Agreement  and  Remaining
                  Participants.  If such  representatives are not employees of a
                  Participant  or a  Remaining  Participant,  such fact shall be

                  Participants.  Representatives  shall agree in writing to: (i)
                  avoid any conflict of interest  that would be  detrimental  to
                  the operation of the San Juan  Project;  and (ii) maintain all
                  proprietary information obtained through such negotiations and
                  discussions  in confidence.  The form of such  confidentiality
                  agreements shall be prepared by the Fuels Committee, and shall
                  be  subject  to the  approval  of the  Participants  which are
                  signatories to the Coal Sales Agreement,  such approval not to
                  be  unreasonably  withheld.  Such  confidentiality  agreements
                  shall be executed by a  Participant's  Coordination  Committee
                  representative  or, as appropriate,  the person  authorized by
                  such Participant or  Representative to execute such documents.
                  Representatives  may be changed by  Participants  or Remaining
                  Participants  by the  giving  of  written  notice to all other
                  Participants and Remaining Participants.

                           20.4.2 Representatives shall make regular reports to,
                  coordinate with, and obtain the  recommendations  of the Fuels
                  Committee  regarding  the  progress of and issues  involved in
                  such coal  negotiations or discussions.  No  representative or
                  Participant   shall  engage  in  bilateral   negotiations   or
                  discussions  concerning  coal  supply to the San Juan  Project
                  with SJCC or any other coal  supplier or  potential  supplier;
                  provided,  however,  that nothing herein shall be construed to
                  prevent  the  Operating  Agent or the  Participants  which are
                  signatories  to the  Coal  Sales  Agreement,  in  the  regular
                  conduct  of  its  or  their  fuel-related   activities,   from
                  maintaining  routine business contacts and communications with
                  SJCC or other coal suppliers or potential suppliers to the San
                  Juan  Project.

         amendment of the Coal Sales  Agreement,  replacement  of the Coal Sales
         Agreement  with a new  agreement or any interim coal pricing  agreement
         related  to the  Coal  Sales  Agreement  (or its  successor)  shall  be
         submitted to the vote of the representatives of the Participants on the
         Fuels  Committee.  Any such action or  determination  shall require the
         affirmative  vote as  established in Section  18.4.3,  except that if a
         Participant's  right to vote has been  suspended  pursuant  to  Section
         35.4.1, the requisite majority for actions or determinations  specified
         in Section  18.4.3  shall be  adjusted in  proportion  to the number of
         Participants whose right to vote has not been suspended.  An example of
         such an adjustment is provided in Exhibit VIII.

                           20.5.1 If, upon such vote,  the  requisite  votes are
                  obtained,  the Participants  which are signatories to the Coal
                  Sales  Agreement  then in effect shall  proceed in  accordance
                  with  the  affirmative  vote of the  Fuels  Committee  without
                  further action of any other San Juan Project committee.

                           20.5.2 If, upon such vote,  the  requisite  votes are
                  not obtained,  the matter  giving rise to the vote shall,  not
                  later than  thirty  (30) days after the  negative  vote of the
                  Fuels Committee,  be submitted to the  Coordination  Committee
                  for its vote in  accordance  with Section 18. If the requisite
                  majorities are obtained in the  Coordination  Committee  vote,
                  the  Participants  which  are  signatories  to the Coal  Sales
                  Agreement then in effect shall proceed in accordance  with the
                  affirmative vote of the Coordination Committee.

                           20.5.3 If the requisite votes are not obtained in the
                  Coordination  Committee  vote,  then  consistent  with Section
                  18.7, the Participants which are signatories to the Coal Sales
                  Agreement  then in effect  shall have the  obligation  and the
                  responsibility,  consistent with Prudent Utility Practice,  to
                  maintain  a supply of coal to the San Juan  Project.

                  20.6 The  Fuels  Committee  shall  keep  written  minutes  and
         records of all meetings.  Any action or determination made by the Fuels
         Committee  shall be reduced to writing and shall become  effective when
         signed by the representatives of the Participants representing a voting
         majority.

                  shall  review  said  method and shall  endeavor  to agree upon
                  whether or not said  unreasonable  burden does actually exist.
                  If, after such review, the Auditing Committee  determines that
                  the  application of said method does result in an unreasonable
                  burden  on  the  Participant,  the  Auditing  Committee  shall
                  determine and recommend a modified method to the  Coordination
                  Committee to eliminate  such  unreasonable  burden.  If, after
                  such review,  the  Auditing  Committee is unable to agree upon
                  whether  or not  such  unreasonable  burden  does  exist or is
                  unable to agree on a  modified  method  for  eliminating  said
                  unreasonable  burden,  the Auditing Committee shall submit the
                  entire matter to the Coordination Committee.

                           22.6.2 The  Coordination  Committee  shall review the
                  recommendation of the Auditing  Committee  pursuant to Section
                  22.6.1.  If,  as a result  of such  review,  the  Coordination
                  Committee agrees that such unreasonable  burden does exist and
                  that a modified method  eliminates such  unreasonable  burden,
                  the Coordination Committee shall adopt said modified method.

                           22.6.3 If the Auditing  Committee has not submitted a
                  recommended  modified  method and the  Coordination  Committee
                  agrees  that  such   unreasonable   burden  does  exist,   the
                  Coordination  Committee  shall endeavor to agree on a modified
                  method. If, after such review,  the Coordination  Committee is
                  unable to agree that such unreasonable burden does exist or on
                  a modified  method  which  will  eliminate  such  unreasonable
                  burden,  upon request of a  Participant,  either matter may be
                  submitted to arbitration pursuant to Section 37.

                           22.6.4   Any   modified   method   adopted   by   the
                  Coordination Committee or determined through arbitration shall
                  be retroactive  for the length of the period of inequity up to
                  a maximum period of three (3) years and shall become effective
                  on the first day following such date of adoption.

                  22.7 As soon as possible  after the end of each calendar year,
         the Operating Agent shall calculate the actual ratios for: A&G, payroll
         tax,  injuries and  damages,  and pension and benefits for such year in
         accordance with the methodologies  described in Exhibit VI (Attachments
         A, B, C and D thereto).  To the extent such  expenses  are more or less
         than those  already  paid by the  Participants  during  said year,  the
         Operating Agent shall bill or credit the Participants for the amount of
         such difference.

                  22.8 At the start of each calendar year,  the Operating  Agent
         shall calculate new ratios for: A&G, payroll tax,  injuries and damages
         and pension and benefits. Such ratios shall be calculated in accordance
         with the methodologies described in Exhibit VI (Attachments A, B, C and
         D thereto).  Such  ratios may be  adjusted  to more nearly  reflect the
         anticipated  expenses of the current year  because of tax  legislation,
         labor contract negotiations or other factors not reflected in the prior
         year's costs.

                  22.9  The  Operating   Agent  shall  bill  to  the  requesting
         Participant(s) the costs and expenses, including A&G expenses, incurred
         by the Operating Agent (including,  but not limited to, fees of outside
         legal counsel or consultants,  time of in-house legal counsel and other
         employees  and  agents  of the  Operating  Agent) in  performing  tasks
         requested by a  Participant  in relation to (i) the offering or sale of
         bonds or other type of security by a Participant in connection with the
         acquisition  or ownership of an interest in the San Juan  Project;  and
         (ii) the attempted or contemplated sale by a Participant of any portion
         of its ownership interest in the San Juan Project.  The Operating Agent
         shall  establish  and maintain  appropriate  accounting  procedures  to
         identify such costs and expenses incurred by the Operating Agent.

         23.0     FUEL COSTS:

                  23.1 The  quantity of coal  delivered  to the San Juan Project
         shall be  determined by the belt scales,  in  accordance  with the Coal
         Sales Agreement.

                  23.2 The  Operating  Agent  shall  maintain  a coal  inventory
         including  an Emergency  Coal  Storage Pile for all Units,  wherein the
         Participants  shall have  Participation  Shares as  provided in Section
         6.2.6.  The Fuels  Committee  shall establish an optimum coal inventory
         tonnage for all Units in total.  Coal inventory  shall be accounted for
         in FERC Account 151.

                  23.3 Costs of the coal  inventory  and fuel  expense  shall be
         apportioned  among and paid for by the  Participants  on the  following
         basis:

                           23.3.1  Costs  that  are  classified  as  Fixed  Fuel
                  Expenses shall be charged to FERC Account 151. Such Fixed Fuel
                  Expenses shall then be charged monthly to FERC Account 501 and
                  shall be apportioned among and paid for by the Participants on
                  the basis of the percentage  that each  Participant's  monthly
                  Net Energy  Generation and auxiliary  generation  bears to the
                  total monthly Net Energy Generation and auxiliary  generation.
                  The Fixed Fuel  Expense  balance in FERC  Account 151 shall be
                  reduced to zero monthly by charging Fixed Fuel Expense to FERC
                  Account 501.  Such Fixed Fuel Expense  shall be adjusted to an
                  annual  reconciliation  among  the  Participants  based on the
                  Participation Shares as provided in Section 6.2.6.

                           23.3.2  Costs that are  classified  as Variable  Fuel
                  Expenses  shall be charged to the fuel  inventory  or credited
                  (as  withdrawn)  to FERC  Account  151 and such costs shall be
                  apportioned  among  and  paid for by the  Participants  on the
                  basis of the  Participation  Shares  as  provided  in  Section
                  6.2.6.  Variable  Fuel Expenses  related to coal  requirements
                  shall be charged to FERC Account 501 as determined by dividing
                  the  total  number  of tons of  coal at the  beginning  of the
                  month,  plus the coal  delivered  during the  month,  into the
                  total recorded  variable cost and multiplying the cost per ton
                  so derived by the number of tons withdrawn.  The Variable Fuel
                  Expenses  shall  be  apportioned  among  and  paid  for by the
                  Participants   on  the  basis  of  the  percentage  that  each
                  Participant's monthly Net Energy Generation bears to the total
                  monthly Net Energy Generation of the Unit(s).

                                    23.3.2.1  Limestone    costs     (chemicals)
                  chargeable to FERC Account 502 shall be apportioned  among and
                  paid for by the  Participants  on the basis of the  percentage
                  that each Participant's monthly Net Energy Generation bears to
                  the total monthly Net Energy Generation of the Unit(s).

                           23.3.3 All other  Variable Fuel Expenses  (including,
                  but not limited to, fuel oil, fuel handling and ash and gypsum
                  disposal)  incurred  which are  chargeable to FERC Account 501
                  shall be apportioned among the Participants in accordance with
                  Section 23.3.2.

                           23.3.4 All Participants acknowledge and recognize the
                  terms and  conditions  of the Coal Sales  Agreement,  wherein,
                  among other terms and conditions, an annual Fixed Fuel Expense
                  must be paid by the San Juan Project  each year to SJCC.  Each
                  Participant  shall pay its  Participant's  Minimum  Fixed Fuel
                  Expense  plus  a  proportional  share  of  Excess  Fixed  Fuel
                  Expense.  Such Excess Fixed Fuel Expense shall be allocated to
                  the Participants based on each Participant's  percentage share
                  of Carry-over Tons created during that calendar year.

                           23.3.5 All  Participants  acknowledge  and  recognize
                  that the monthly  allocation of Fixed Fuel  Expenses  based on
                  the monthly Net Energy  Generation,  as  described  in Section
                  23.3.1,  may result in an individual  Participant  having been
                  allocated  Minimum  Fixed Fuel  Expense and Excess  Fixed Fuel
                  Expense equal to, less than, or greater than its  proportional
                  share of such expenses.  Any  overpayment or underpayment of a
                  Participant's Minimum Fixed Fuel Expense and Excess Fixed Fuel
                  Expense  shall  be  included  as an  adjustment  to the  final
                  Participant fuel invoices in a given year.  Payments  received
                  from  Participants  which have underpaid during the year shall
                  be used by the  Operating  Agent to pay  SJCC for any  Minimum
                  Fixed  Fuel   Expense  not  paid  and  to   compensate   other
                  Participants which have overpaid.

                           23.3.6 All Participants acknowledge and recognize the
                  provisions of the Coal Sales Agreement that create  Carry-over
                  Tons. To the extent that  Carry-over Tons are created and paid
                  for by individual  Participants,  the Carry-over  Tons will be
                  allocated  to each  Participant's  Carry-over  Tons Account in
                  proportion  to each  Participant's  allocation of Excess Fixed
                  Fuel  Expense for the  calendar  year.  At the  direction of a
                  Participant,  the Operating  Agent shall  transfer  Carry-over
                  Tons from an individual  Participant's Carry-over Tons Account
                  to another Participant's  Carry-over Tons Account.  Carry-over
                  Tons shall be accounted for on the basis of tonnage only, with
                  no financial value attached thereto.  Participants shall apply
                  any existing Carry-over Tons from their account to the payment
                  of a minimum tonnage deficiency invoice.  When Carry-over Tons
                  are  used  by  the  San  Juan  Project,   Participants   whose
                  Carry-over  Tons Accounts are reduced shall be  compensated by
                  Participants whose Carry-over Tons Accounts have no balance or
                  an inadequate  balance to meet their obligation for the Annual
                  Minimum Coal Delivery. The value of this compensation shall be
                  based on the actual cost billed by SJCC.

                           23.3.7 All Participants acknowledge and recognize the
                  provisions of Exhibit VII,  attached  hereto and  incorporated
                  herein,  as  representative  of  the  allocation  and  billing
                  methodology  agreed upon.  Exhibit VII reflects the allocation
                  of expenses among the  Participants  based on actual  expenses
                  incurred for fuel expense for the month of January 1993.

                  23.4 The  Operating  Agent shall  provide the  Participants  a
         monthly   written  report  on  the  following  items  related  to  coal
         deliveries at the San Juan Project:



                           23.4.1   Annual Minimum Coal Delivery for the year.

                           23.4.2 Annual Minimum Coal Delivery  allocated  among
                  the Participants.

                           23.4.3  Total actual coal  deliveries  by SJCC to the
                  San Juan Project for each month and for the year to date.

                           23.4.4 Total actual coal  deliveries  to the San Juan
                  Project for each month and for the year to date,  allocated to
                  the Participants.

                           23.4.5 Total cost and tonnage of inventory  allocated
                  to the Participants.

                           23.4.6 Fixed Fuel  Expense and Variable  Fuel Expense
                  allocated to the  Participants for each month and for the year
                  to date.

                           23.4.7  Status  of  Carry-over  Tons for the San Juan
                  Project,  allocated to the  Participants.

                  23.5  The  Operating  Agent  shall  replace  the  tons of coal
         withdrawn from  inventory on a ton for ton basis  according to the coal
         withdrawn  from  inventory  for the month,  except  where  modified  to
         reflect  anticipated  generation usage in the following month. The cost
         of this  replacement  shall be apportioned  among the  Participants  in
         accordance with Sections 23.2 and 23.3.

                  23.6 In the event that SJCC defaults in its obligations  under
         the Coal Sales  Agreement,  the Operating Agent may assume or make such
         arrangements  for  the  assumption  of  such  of  SJCC's  operation  as
         permitted by the Coal Sales  Agreement.  Costs associated with the coal
         operations  shall  become  a part of the  Total  Monthly  Coal  Cost as
         applicable  and,  with the  costs  and  expenses  of fuel and  emission
         residuals and ash disposal,  shall be apportioned  between and paid for
         by the Participants in accordance with this Section 23.

                  23.7  The  monthly  costs  of  coal   allocated   between  the
         Participants  in accordance  with this Section 23 shall be estimated by
         the Operating Agent as soon as practicable  after the end of each month
         and a  preliminary  bill shall be presented  and paid in the manner set
         forth in Section 30.3.3.  Adjustments in the estimated preliminary bill
         due to  quality  and  quantity  of coal  delivered,  and  estimates  of
         escalation,  shall  be  made in the  next  succeeding  month  or on the
         earliest possible billing thereafter.

                  23.8 In the event of a catastrophic  occurrence  which results
         in  a  sustained   outage  of  a  Unit  and  a   declaration   that  an
         uncontrollable  force  exists under the Coal Sales  Agreement,  then in
         such event,  FERC Account 151 will be allocated to the  commercial  and
         non-commercial  Units. The portion of FERC Account 151 allocated to the
         non-commercial  Unit(s)  shall  remain  frozen  until such time as such
         Unit(s)  is  restored  to  commercial  operation.  New  costs  of  coal
         chargeable  to  FERC  Account  151  will  be   apportioned   among  the
         Participants on the basis of the Participants'  Participation  Share in
         the  generating  capacity of the  commercial  Units.  At such time as a
         damaged Unit is restored to commercial operation, the frozen portion of
         Account  151 will be  merged  into the  operating  unit(s)  portion  of
         Account 151 and to the extent that a Participant is adversely  impacted
         by an  incremental  increase  in the  average  unit  cost  of  coal  an
         allocation of such incremental cost will be made and the net difference
         paid to the Participant having a credit balance.

                  23.9 The  accounting  practice as stated in this Section 23 is
         applicable  at the  present  time.  If,  however,  at a later  time the
         practice is proven to be inadequate or another practice later proves to
         be  more  equitable  in the  opinion  of the  Auditing  Committee,  the
         Coordination  Committee,   upon  the  recommendation  of  the  Auditing
         Committee,  may  authorize  changes  and  revisions  to the  accounting
         practices.

         24.0     ANNUAL BUDGETS:

                  24.1 Not less than ninety (90) days prior to the  beginning of
         each calendar year, the Operating Agent shall prepare and submit to the
         Engineering  and  Operating  Committee  for its review and approval the
         proposed  capital  budget,   manpower  budget  and  a  budget  for  the
         performance of Operating Work for such calendar year.

                  24.2 The Engineering and Operating Committee shall approve the
         budgets  described  in Section  24.1 in final form not less than thirty
         (30) days  prior to their  effective  date.  In the event that any such
         budget  is not so  approved,  the  Operating  Agent  will  nevertheless
         continue to perform  Operating Work in a manner consistent with Prudent
         Utility Practice until such time as a budget has been approved.

                  24.3 Any  information  required from the  Participants  by the
         Operating Agent in preparing such proposed  budgets will be supplied by
         the  Participants,  if possible,  within  thirty (30) days  following a
         request by the Operating Agent.

                  24.4 The Engineering  and Operating  Committee may at any time
         during the year approve revisions to the approved capital  expenditures
         budget,  manpower  budget and a budget for the performance of Operating
         Work.

         25.0     PAYMENT OF TAXES:

                  25.1 The Participants shall use their best efforts to have any
         taxing  authority  imposing  any taxes or  assessments  on the San Juan
         Project,  assess and levy such taxes or  assessments  directly  against
         each Participant in accordance with its respective  Participation Share
         in the property taxed.

         30.0     PAYMENT OF EXPENSES BY PARTICIPANTS:

         in  accordance  with  this  Agreement  shall  be  made  payable  to the
         Operating  Account  established by the Operating  Agent.  The Operating
         Funds  shall  be  owned  by the  Participants  in  proportion  to their
         respective  balances therein at any given time, and the Operating Agent
         in its  capacity  as such  shall  not have any  right or title  therein
         except to maintain  custody of and to disburse the Operating Funds as a
         conduit between the Participants  and those to whom such  disbursements
         shall be made.

                  30.2 The Engineering and Operating Committee shall establish a
         minimum  amount for the Operating  Funds which will be available to pay
         for  expenditures  or  obligations  incurred  by or on  behalf  of  the
         Participants in accordance with this Agreement.  Such minimum amount of
         Operating  Funds  may be  revised  by  the  Engineering  and  Operating
         Committee at any time.  The minimum  amount of the Operating  Funds and
         any  increases  therein  shall  be  advanced  by  the  Participants  in

         effective.  In  the  event  the  Engineering  and  Operating  Committee
         decreases such minimum amount,  then each  Participant  shall receive a
         credit  which shall be equal to the product of its  percentage,  as set
         forth in Section 22, and the amount of any such decrease.

         accordance with this Agreement, as follows:

                           30.3.1 Expenses described in Sections 30 and 22 shall

                  they shall be billed within a reasonable  time following their
                  incurrence.

                  31.3 In the event that another Participant's insurance program
         affords equal or better  coverage on a more  favorable  cost basis than
         that available to the Operating  Agent,  the Participants may agree (by
         separate  agreement)  that such  insurance  program  may be utilized to
         afford all or part of the insurance coverage required by Section 31.1.

                  31.4 The insurance company used, the insurable values, limits,
         deductibles,   retentions  and  other  special  terms,   covenants  and
         conditions  of the  Operating  Insurance  shall be  agreed  upon by the
         Coordination Committee.

                           31.4.1  Any  deductibles   shall  be  shared  by  the
                  Participants in accordance with the percentages established in
                  Section 22.1.

                  31.5  The   Operating   Agent  shall   furnish   each  of  the
         Participants  with either a certified  copy of each of the  policies of
         Operating  Insurance or a certified copy of each of the policy forms of
         Operating  Insurance,  together  with a line  sheet  therefor  (and any
         subsequent  amendments)  naming the insurers and  underwriters  and the
         extent of their  participation.  When the  policies or policy  forms of
         Operating  Insurance  have  been  approved  in  writing  by  all of the
         Participants,  said  policies or policy  forms shall not be modified or
         changed by any Participant  without the prior written consent of all of
         the  Participants,  except  for  minor  and  insubstantial  changes  or
         modifications, as to which notification shall be given by the Operating
         Agent to the Participants.

                  31.6  Each  of  the  Operating  Insurance  policies  shall  be

<PAGE>

                  31.7 Operating  Insurance  policies shall be primary insurance
         for all purposes and shall be so endorsed.  Any insurance  carried by a
         Participant  individually  shall  not  participate  with the  Operating
         Insurance as respects any loss or claim for which valid and collectible
         Operating  Insurance  shall  apply.  Such other  insurance  shall apply
         solely as respects the individual interest of the Participant  carrying
         such other insurance.

                  31.8 Nothing herein shall prohibit the Operating  Agent or any
         Participant  from  furnishing  a policy of  Operating  Insurance  which
         combines the coverage  required by this Agreement with coverage outside
         the scope of that required by this Agreement. If the Operating Agent or
         any  Participant  furnishes  a  policy  of  Operating  Insurance  which
         combines the coverage  required by this Agreement with coverage outside
         the  scope  of  that  required  by  this  Agreement,  the  Coordination
         Committee shall agree on the portion of the total premium cost which is
         allocable to Operating  Insurance.  If the  Participants  are unable to
         agree on such  allocation,  the  Operating  Agent may make an estimated
         allocation  and  bill  the  Participants  on the  basis  thereof,  with
         adjustment to be made when the dispute is resolved.

                  31.9  If  a  Participant  desires  changes  in  any  Operating
         Insurance policy, such Participant shall notify the Operating Agent and
         the  other  Participants  in  writing  of  the  desired  changes.  Upon
         agreement of the Coordination  Committee to such change,  the Operating
         Agent shall obtain the  insurance  within sixty (60) days from the date
         of agreement.  If the  Operating  Agent is unable to obtain the type of
         policy or coverage  required  herein or believed by the Operating Agent
         to be adequate,  then the Operating Agent shall immediately  notify the
         Participants.

                  31.10 In the event  the  Coordination  Committee  is unable to
         agree  upon  any  matters  relating  to the  Operating  Insurance,  the
         Operating  Agent,  pending the resolution of such  disagreement,  shall
         procure or cause to be procured such policies of insurance,  consistent
         with  Prudent  Utility  Practice,  as  are  necessary  to  protect  the
         Participants  against the insurable risks for which Operating Insurance
         is  required.  During any period of  negotiations  with an insurer,  or
         other negotiations which are pending at the expiration of the period of
         coverage of an Operating Insurance policy, or in the event an Operating
         Insurance  policy is canceled,  the Operating Agent shall renew or bind
         policies as an emergency measure,  or may procure policies of insurance
         which are identical to those which were canceled,  or may to the extent
         possible secure replacement  policies which will provide  substantially
         the same coverage as the policy expiring or canceled.

                  31.11 Each  Participant  shall have the right to request  that
         any  mortgagee,  trustee or secured party be named on all or any of the
         Operating  Insurance policies as loss payees or additional  assureds as
         their  interests  may appear.  Such  request  shall be submitted to the
         Operating Agent specifying the name or names of such mortgagee, trustee
         or secured party and such additional information as may be necessary or
         required  to permit it to be  included  on the  policies  of  Operating
         Insurance.

                  31.12 On an annual basis, the Operating Agent shall advise the
         Participants  on the  status  of  insurance  coverage  for the San Juan
         Project and shall make appropriate recommendations concerning insurance
         issues to the Coordination Committee.

         32.0     SURPLUS OR RETIRED PROPERTY:

         The Operating  Agent shall  dispose of surplus  property or property no
longer used or useful in the  operation  of the San Juan Project and report such
disposal to the  Participants,  both in accordance with practices and procedures
established by the Engineering and Operating  Committee.  The proceeds from such
disposition  shall be  credited to the  Participants  in  accordance  with their
Participation Shares.

         33.0     REMOVAL OF OPERATING AGENT:

                  33.1 The  Operating  Agent shall serve as such during the term
         of this Agreement unless it resigns as Operating Agent by giving notice
         to the  Participants  at least one (1) year in  advance  of the date of
         resignation  or until receipt by the  Operating  Agent of notice of its
         removal as provided in Section 33.2.

                  33.2 The Operating Agent may be removed as Operating Agent for
         any one of the following reasons:

                           33.2.1 The  Operating  Agent may be removed by action
                  of the  Coordination  Committee  if,  in the  judgment  of the
                  Coordination  Committee  (voting  as  provided  for in Section
                  18.4), the best interests of the San Juan Project require that
                  a new Operating Agent be selected.  Any Participant  seeking a
                  Coordination  Committee  determination to remove the Operating
                  Agent shall provide to the  Operating  Agent and to all of the
                  Participants a written  statement,  detailing the reasons why,
                  in the judgment of the initiating  Participant,  the Operating
                  Agent should be removed. Within thirty (30) days after receipt
                  by  the  Operating  Agent  of  this  written  statement,   the
                  Operating  Agent  shall  prepare  and  serve  upon  all of the
                  Participants  its  response  which  shall  contain a  detailed
                  rebuttal of the allegations made in the initiating  statement.
                  Within the same thirty (30) day period,  any other Participant
                  may also  prepare and serve upon the  Operating  Agent and the
                  Participants a statement  responding to the allegations in the
                  initiating statement. Within twenty (20) days after service of
                  all such response statements, the Coordination Committee shall
                  meet to consider  what action,  if any, to take with regard to
                  the  removal of the  Operating  Agent.  If,  pursuant  to this
                  Section  33.2.1,   the  Coordination   Committee  removes  the
                  Operating Agent, such removal shall be effective upon the date
                  established by the  Coordination  Committee.  If the Operating
                  Agent or any  Participant is  dissatisfied  with the action of
                  the  Coordination  Committee,  it shall have the right to seek
                  arbitration  under  Section 37, but no demand for  arbitration
                  shall  stay the  decision  of the  Coordination  Committee  to
                  remove the Operating Agent.

                           33.2.2 If,  pursuant to the provisions of Section 34,
                  it is determined that the Operating Agent is in default of its
                  obligations  under this Agreement,  the Operating Agent may be
                  removed  by  written  notice  given by any  Participant  under
                  Section 34.1.2, which notice shall state the effective date of
                  the removal of the Operating Agent.

                           33.2.3 Notwithstanding the pendency of any actions to
                  remove the Operating Agent, the Operating Agent shall continue
                  in good faith to exercise its obligations as Operating  Agent.

                  33.3  Prior  to the  effective  date of a  resignation  of the
         Operating Agent, or prior to the date of removal of the Operating Agent
         in accordance  with Section 33.2, the  Coordination  Committee shall by
         written agreement  designate a new Operating Agent, which may, but need
         not, be a  Participant.  The  Coordination  Committee  may designate an
         interim  Operating  Agent  pending  selection of a permanent  Operating
         Agent. Acceptance by the new Operating Agent of its appointment as such
         shall  constitute  its  agreement  to perform  the  obligations  of the
         Operating Agent under this Agreement.

         34.0     DEFAULTS BY OPERATING AGENT:

                  34.1 The following  provisions shall apply solely in regard to
         violations  or  allegations  of  violations  of this  Agreement  by the
         Operating Agent on the basis of which removal of the Operating Agent is
         sought:

                           34.1.1 In the event any  Participant  shall be of the
                  opinion  that an  action  taken or  failed  to be taken by the
                  Operating Agent constitutes a violation of this Agreement,  it
                  may give written notice thereof to the Operating Agent and the
                  other Participants, together with a statement of the basis for
                  its  opinion.  Thereupon,  the  Operating  Agent may prepare a
                  statement of the reasons  justifying  its action or failure to
                  take  action.  If  agreement  in  settling  the dispute is not
                  reached between the Operating Agent and such Participant which
                  gave  such  notice,  then the  matter  shall be  submitted  to
                  arbitration  in the manner  provided in Section 37. During the
                  continuance  of the  arbitration  proceedings,  the  Operating
                  Agent may continue  such action taken or failed to be taken in
                  the manner it deems most  advisable and  consistent  with this
                  Agreement.

                           34.1.2 If it is determined  that the Operating  Agent
                  is violating this  Agreement,  then the Operating  Agent shall
                  act with due diligence to end such violation and shall, within
                  thirty  (30) days or within such  lesser  time  following  the
                  determination as may be prescribed in the determination,  take
                  action or  commence  action in good  faith to  terminate  such
                  violation. In the event that the complaining Participant is of
                  the opinion that the Operating Agent has not taken such action
                  to correct,  or to commence  action to correct,  the violation
                  within such allowed period, the complaining  Participant shall
                  be entitled to submit the  question of the  Operating  Agent's
                  good faith action to terminate  such  violation to arbitration
                  as  provided  in  Section  37.  If it is  determined  that the
                  Operating Agent has not acted with due diligence or good faith
                  to  terminate  such  violation,  it shall be  deemed  to be in
                  default and shall be subject to removal, after the arbitration
                  determination,  within  fifteen  (15) days  after  receipt  of
                  notice executed by the  complaining  Participant in accordance
                  with Section 42.

                           34.1.3  The  provisions  of  Section  35,   excepting
                  Sections  35.8 and 35.9,  shall not  apply to  disputes  as to
                  whether or not an action or non-action of the Operating Agent,
                  in its capacity as Operating  Agent, is a violation or default
                  under this Agreement.

                                    PART VII

                       DEFAULTS, LIABILITY AND ARBITRATION

         35.      DEFAULTS:

                  35.1 Each  Participant  shall pay all monies and carry out all
         other  performances,  duties  and  obligations  agreed  to be  paid  or
         performed by it pursuant to all of the terms and  conditions  set forth
         and  contained  in  the  Project  Agreements,  and  a  default  by  any
         Participant  in the  covenants  and  obligations  to be by it kept  and
         performed  pursuant to the terms and conditions set forth and contained
         in any of the Project  Agreements shall be an act of default under this
         Agreement.

                  35.2 In the event of a default by a Participant  in any of the
         terms  and  conditions  of  this  Agreement  to be  performed  by  that
         Participant, the following shall apply:

                           35.2.1  The  Operating  Agent  shall  give a  written
                  notice of the default to the  defaulting  Participant  and the
                  other Participants in accordance with Section 35.2.2.

                           35.2.2  The  notice  of  default  shall  specify  the
                  existence,  nature and extent of the default.  Upon receipt of
                  the  notice  of  default,  the  defaulting  Participant  shall
                  immediately  take all steps  necessary  to cure the default as
                  promptly and  completely  as possible.

                  35.3 In the  event  that  any  Participant  shall  dispute  an
         asserted  default by it, then such  Participant  shall pay the disputed
         payment  or  perform  the  disputed  obligation,  but  may do so  under
         protest. The protest shall be in writing,  shall accompany the disputed
         payment or precede the performance of the disputed  obligation(s),  and
         shall  specify the reason  upon which the  protest is based.  Copies of
         such  protest  shall  be  mailed  by  such  Participant  to  all  other
         Participants  and to the  Operating  Agent.  Payments  not  made  under
         protest shall be deemed correct,  except to the extent that periodic or


                                      103
<PAGE>

         annual audits may reveal over or under payment by a Participant  or may
         necessitate adjustments.  In the event it is determined by arbitration,
         pursuant to the  provisions of this  Agreement or  otherwise,  that the
         protesting Participant is entitled to a refund of all or any portion of
         a disputed  payment  or  payments,  or is  entitled  to the  reasonable
         equivalent  in  money  of   non-monetary   performance  of  a  disputed
         obligation  theretofore  made,  then,  upon  such  determination,   the
         non-protesting  Participant(s)  shall  reimburse  such  amount  to  the
         protesting  Participant,  together with interest thereon at the rate of
         ten percent  (10%) per annum,  or the maximum  legal rate of  interest,
         whichever is lesser,  from the date of payment or of the performance of
         a disputed obligation to the date of reimbursement.

                  35.4 In the event a default shall continue for a period of ten
         (10) days or more  after the  notice  given by the  Operating  Agent in
         accordance   with  Section  35.2  without  having  been  cured  by  the
         defaulting  Participant,  or without such defaulting Participant having
         commenced or continued  action in good faith to cure such default,  the
         following shall apply:

                           35.4.1 If the  defaulting  Participant  has failed to
                  cure such default or to commence such good faith action during
                  said ten (10) day  period,  the  Operating  Agent shall make a
                  written  report to the  Engineering  and  Operating  Committee
                  concerning  the status of the default  and shall,  on the next
                  working  day  after  such  ten  (10) day  period,  notify  the
                  defaulting  Participant  in writing that the  Operating  Agent
                  intends to declare the defaulting Participant in default under
                  the Project  Agreements  unless  there is a prompt cure of the
                  default. Seven (7) days after the giving of such notice to the
                  defaulting  Participant,  the  Operating  Agent  shall  make a
                  second  written  report  to  the   Engineering  and  Operating
                  Committee  concerning  the  status  of  the  default  and  the





                                      104
<PAGE>

                  efforts,  if any, of the  defaulting  Participant  to cure the
                  default.  If, within seven (7) additional days, the defaulting
                  Participant has neither cured nor reasonably commenced to cure
                  the default,  the Operating Agent shall declare the defaulting
                  Participant in default under the Project  Agreements and shall
                  provide written  notification of the declaration of default to
                  the  defaulting   Participant   and  to  the  Engineering  and
                  Operating  Committee.  Thereafter,  and  for  so  long  as the
                  default is not remedied and the  declaration of default is not
                  revoked by the Operating  Agent,  all rights of the defaulting
                  Participant  under the Project  Agreements shall be suspended,
                  including the right to vote on all  committees  and to receive
                  all or  any  part  of  its  proportionate  share  of  the  Net
                  Effective Generating Capacity.

                           35.4.2 Within seventeen (17) days after the notice by
                  the  Operating  Agent,  as provided for in Section  35.2,  the
                  Operating Agent shall prepare special operating procedures for
                  approval by the Engineering and Operating  Committee that will
                  apply during the period of suspension  under  Section  35.4.1.
                  Upon approval by the Engineering and Operating Committee,  the
                  Operating  Agent shall provide  notice to each  Participant of
                  such  special  procedures.   These  special  procedures  shall
                  include:

                                    35.4.2.1  A  tabulation  in form  similar to
                  Section  6.2 of the  percentages  of  costs to be borne by the
                  non-defaulting Participants pursuant to Section 35.5;

                                    35.4.2.2  Billing  and  accounting  of  such
                  costs;

                                    35.4.2.3  Dispatch  and  scheduling  of  the
                  defaulting Participant's  proportionate share of Net Effective
                  Generating Capacity; and


                                      105
<PAGE>

                                    35.4.2.4  Any other items  required  for the
                  optimal  use of the San Juan  Project  and the  mitigation  of
                  damages by the non-defaulting Participants.

                                    35.4.2.5 If the Operating  Agent proposes to
                  broker  all  or a  portion  of  the  defaulting  Participant's
                  proportionate  share of Net Effective  Generating  Capacity on
                  behalf of one or more non-defaulting Participants, the form of
                  such an agreement shall be incorporated in such procedures.

                           35.4.3 Within twenty (20) days after the  declaration
                  of  a  default,   as  provided  for  in  Section  35.4.1,  the
                  defaulting  Participant  and the  non-defaulting  Participants
                  shall   convene   a  meeting   to   address   the   defaulting
                  Participant's  situation  and its  intentions  with  regard to
                  curing its default. The defaulting  Participant shall promptly
                  prepare  a  cure  plan  for  approval  by the  members  of the
                  Coordination Committee entitled to vote thereon. The cure plan
                  shall address the  defaulting  Participant's  plan to cure the
                  default and restore itself to full  participation  as an owner
                  of the San Juan Project. The Coordination  Committee,  by vote
                  of the members of the Coordination  Committee entitled to vote
                  thereon, will monitor the defaulting  Participant's compliance
                  with the  terms  and  conditions  of the  cure  plan and if it
                  appears  to the  Coordination  Committee  that the  defaulting
                  Participant  is or will be unable to comply  with the terms of
                  an  approved  cure  plan,  the  Coordination  Committee  shall
                  consider   what  actions  may  be  required  to  address  such
                  inability,  including,  but  not  limited  to,  directing  the
                  Operating Agent to take such actions as may be appropriate. It
                  is the intent of the  Participants  that any defaults shall be
                  cured on as expeditious a basis as reasonably possible.

                           35.4.4  A  demand  for  arbitration  of  an  asserted
                  default  pursuant to Section 37 shall not stay the  suspension
                  of the rights of the defaulting Participant,  but in the event
                  that  the  board  of  arbitrators  shall  determine  that  the
                  asserted   default  did  not  in  fact  exist  or  occur,  the
                  arbitrators  shall  specify  a  method  of  fully  and  fairly
                  compensating the Participant  which, under Section 35.4.1, was
                  denied the right to vote on  committee  actions and to receive
                  all or  any  part  of  its  proportionate  share  of  the  Net
                  Effective Generating Capacity.

                  35.5 During any period  when the  suspension  provided  for in
         Section 35.4.1 is in effect, the non-defaulting Participant(s) having a
         Participation  Share in the  affected  Unit or Units:  (i) shall bear a
         proportionate share of all expenses,  including but not limited to, the
         operation and maintenance costs,  insurance costs, fuel costs,  capital
         expenditures  and other  expenses  otherwise  payable by the defaulting
         Participant  under the Project  Agreements,  including any  obligations
         related to common equipment and facilities,  based upon the relation of
         the Participation Share of each such  non-defaulting  Participant(s) to
         the  Participation  Shares of all  non-defaulting  Participants  in the
         specific  Unit or Units;  and (ii) shall be entitled  to  schedule  and
         receive  for  their  accounts  their  proportionate  share  of the  Net
         Effective Generating Capacity of the defaulting Participant.

                  35.6  In  connection  with  its  cure  of  the  default,   the
         defaulting   Participant   shall  pay  promptly   upon  demand  to  the
         non-defaulting  Participant(s)  the total  amount of money  (and/or the
         reasonable equivalent in money of non-monetary performance) paid and/or
         made by such non-defaulting  Participant(s) pursuant to Section 35.5 in
         order to cure any default by the defaulting Participant,  together with
         interest  thereon at the rate of ten  percent  (10%) per annum,  or the
         maximum legal rate of interest,  whichever is the lesser, from the date
         of the  expenditure  of  such  money  (or  the  making  of  such  other
         performance) by the non-defaulting Participant(s),  to the date of such
         reimbursement by the defaulting Participant,  or such greater amount as
         may be  otherwise  provided  in the  Project  Agreements.  Any  payment
         obligation of the defaulting Participant shall be reduced by mitigation
         measures  undertaken  by  the  non-defaulting  Participants;  provided,
         however,  that the payment  obligations of the  defaulting  Participant
         shall  not  be  reduced  by  any  profits  or  gains  achieved  by  the
         non-defaulting  Participants  as the  result of taking a  proportionate
         share of the Net  Effective  Generating  Capacity due to the default of
         the defaulting Participant.

                  35.7  The  suspension  of a  defaulting  Participant  shall be
         terminated  and its full rights under the Project  Agreements  restored
         when the default(s) have been cured and all compensable  costs incurred
         by the  non-defaulting  Participant(s)  hereunder have been paid by the
         defaulting   Participant  or  other  arrangements   acceptable  to  the
         non-defaulting Participant(s) have been made.

                  35.8 No waiver by a  non-defaulting  Participant of its rights
         with respect to a default under this Agreement,  or with respect to any
         other  matter  arising  in  connection  with this  Agreement,  shall be
         effective  unless the  non-defaulting  Participant(s)  waive in writing
         their respective rights and any such waiver shall not be deemed to be a
         waiver with respect to any subsequent default or matter. No delay short
         of the statutory  period of  limitations  in asserting or enforcing any
         right hereunder shall be deemed a waiver of such right.

                  35.9 The rights and remedies  provided in this Agreement shall
         be in addition to the rights and  remedies of the  Participants  as set
         forth and  contained in any other  Project  Agreement or any rights and
         remedies the Participants have in law or equity.

         or (ii) the  performance or  nonperformance  of the  obligations of any
         Participant  under  any of  the  Project  Agreements,  other  than  the
         obligation to pay any monies becoming due.

                           36.1.1 In the event any insurer  providing  insurance
                  refuses to pay any judgment obtained by a Participant  against
                  any other Participant, its directors, members of its governing
                  body,  officers or employees on account of liability  referred
                  to in Section 36.1, the Participant, its directors, members of
                  its  governing  body,  officers or employees  against whom the
                  judgment is obtained  shall,  at the request of the prevailing
                  Participant and in  consideration  for the covenant granted in
                  Section  36.1,  execute such  documents as may be necessary to
                  effect an assignment  of its  contractual  rights  against the
                  nonpaying insurer and thereby give the prevailing  Participant
                  the opportunity to enforce its judgment  directly against such
                  insurer.  In no event when a judgment debt is collectible from
                  valid insurance  shall the Participant  obtaining the judgment
                  execute,  levy or otherwise  enforce the  judgment  (including
                  recording   or   effecting  a  judgment   lien)   against  the
                  Participant,  its  directors,  members of its governing  body,
                  officers or employees against whom the judgment was obtained.

                           36.1.2 To the extent that Section 41-3-5,  New Mexico
                  Statutes  Annotated,  1978 compilation (as such section may be
                  amended), shall be applicable and for the purpose of relieving
                  each  Participant,  its  directors,  members of its  governing
                  body,   officers  and  employees  of  any  liability  to  make
                  contribution  to  other   non-Participant   tortfeasors,   the
                  foregoing  covenant not to execute  hereby effects a reduction
                  of all injured  Participants'  damages recoverable against all
                  other  non-Participant  tortfeasors  to the  extent of the pro
                  rata  share (as  referred  to in  Section  41-3-5,  New Mexico
                  Statutes Annotated,  1978 compilation,  as such section may be
                  amended) of the other Participants,  their directors,  members
                  of their governing bodies, officers and employees.

                           36.1.3 Each Participant  agrees,  upon request by any
                  other  Participant,  to make,  execute and deliver any and all
                  documents  or take  such  other  action as may  reasonably  be
                  required to effectuate  the intent of this Section 36.1.

                  36.2 Except as provided in Sections  36.4,  36.5 and 36.6, the
         costs and expenses of discharging  all work liability  imposed upon one
         or  more  of  the  Participants,  for  which  payment  is not  made  by
         insurance,  shall be allocated among the  Participants in proportion to
         their  respective  Participation  Shares in the property giving rise to
         the work  liability.  Work  liability is defined as liability of one or
         more Participants for any loss, damage,  claim, cost, charge or expense
         of any kind or nature  (including  direct,  indirect or  consequential)
         suffered or incurred by any party other than a Participant,  whether or
         not  resulting  or to result in the future from the  negligence  of any
         Participant,  its directors,  members of its governing body,  officers,
         employees  or any  other  person or entity  whose  negligence  would be
         imputed to such  Participant,  that has  resulted  or may result in the
         future  from (i)  performance  or  nonperformance  of the  work  herein
         described,  (ii)  operation,  maintenance,  use or ownership of the San
         Juan Project, and (iii) past or future performance or nonperformance of
         the obligations of any Participant under any of the Project Agreements.

                  36.3 If it cannot be  determined  which  property gave rise to
         work  liability,  the  allocation  for  discharging  costs and expenses
         associated therewith shall be as specified in Section 22.1.7.

                  36.4 Except for liability resulting from Willful Action (which
         subject to the  provisions of Section 36.6 shall be the  responsibility
         of the willfully acting  Participant),  any Participant  whose electric
         customer  shall  have a claim or  bring an  action  against  any  other
         Participant for any death,  injury, loss or damage arising out of or in
         connection  with  electric  service  to  such  customer  caused  by the
         operation  or  failure  of  operation  of the San Juan  Project  or any
         portion   thereof   shall   indemnify  and  hold  harmless  such  other
         Participant, its directors, members of its governing body, officers and
         employees from and against any liability for such death,  injury,  loss
         or damage.

                  36.5 Each  Participant  shall be  responsible  for any damage,
         loss,  claim,  cost, charge or expense that is not covered by insurance
         and results  from its own Willful  Action as defined in Section  5.53.2
         and shall  indemnify  and hold harmless the other  Participants,  their
         directors,  members of their governing bodies,  officers and employees,
         from any such damage, loss, claim, cost, charge or expense.

                  36.6  Except  as  provided  in  Section  36.5,  the  aggregate
         liability  of any  Participant  to all other  Participants  for Willful
         Action not covered by insurance shall be determined as follows:

                           36.6.1  All  such  liability  for  damages,   losses,
                  claims,  costs,  charges or expenses of such Participant shall
                  not exceed ten million dollars  ($10,000,000)  per occurrence.
                  Each  Participant  extends  to  each  other  Participant,  its
                  directors,   members  of  its  governing  body,  officers  and
                  employees  its  covenant  not to  execute,  levy or  otherwise
                  enforce a judgment  against any of them for any such aggregate
                  liability in excess of ten million dollars  ($10,000,000)  per
                  occurrence.

                           36.6.2  A  claim  based  on  Willful  Action  must be
                  perfected by filing suit in a court of competent  jurisdiction
                  within three (3) years after the Willful  Action  occurs.  All
                  claims made  thereafter  relating to the same  Willful  Action
                  shall be  barred  by this  Section  36.6.2.  The award to each
                  nonwillfully   acting   Participant   from  each   Participant
                  determined  to  have   committed   Willful   Action  shall  be
                  determined as follows:  (i) Each  Participant who successfully
                  files suit for  remuneration  shall  receive the lesser of (a)
                  its final judgment awarded (or settlement made) or (b) its pro
                  rata   Participation   Share   of  the  ten   million   dollar
                  ($10,000,000)  maximum recovery established in Section 36.6.1;
                  (ii) When all pending suits are resolved,  those  Participants
                  who were awarded  judgments or reached  settlements  but whose
                  claims were not fully satisfied  pursuant to Section 36.6.2(i)
                  shall be entitled to participate  in any remaining  portion of
                  the ten million dollar  ($10,000,000)  maximum recovery limit,
                  based  upon  the  ratio  of the  unsatisfied  portion  of such
                  Participant's  judgment or settlement to the total unsatisfied
                  portion  of  all  such   judgments   and   settlements.   Such
                  participation   shall   be   limited   to  the   Participants'
                  unsatisfied  judgments or settlements.

                  36.7 The  provisions of this Section 36 shall not be construed
         so as to relieve any  insurer of its  obligation  to pay any  insurance
         proceeds  in  accordance  with the  terms and  conditions  of valid and
         collectible insurance policies.

                  36.8 If a court of competent  jurisdiction  determines  upon a
         challenge  by a  Participant  or third  party  that the  provisions  of
         Section 56-7-1, New Mexico Statutes  Annotated,  1978 compilation,  are
         applicable to this Agreement, the Participants agree that any agreement
         to indemnify contained in this Agreement shall not extend to liability,
         claims, damages, losses or expenses, including attorney's fees, arising
         out of:

                           (i) the  preparation  or approval of maps,  drawings,
                  opinions,   reports,   surveys,   change  orders,  designs  or
                  specifications  by the indemnitee,  or the agents or employees
                  of the indemnitee; or

                           (ii) the giving of or the failure to give  directions
                  or instructions by the indemnitee,  or the agents or employees
                  of the  indemnitee,  where  such  giving  or  failure  to give
                  directions  or  instructions  is the  primary  cause of bodily
                  injury to persons or damage to property.

                  The word  "indemnify"  as used in this Section 36.8  includes,
         without  limitation,  an agreement  to remedy  damage or loss caused in
         whole or in part by the negligence,  act or omission of the indemnitee,
         the agents or  employees  of the  indemnitee,  or any legal  entity for
         whose negligence, acts or omissions any of the foregoing may be liable.

                  36.9 The Participants agree that the aggregate liability limit
         of ten million dollars ($10,000,000)  referenced in Sections 36.6.1 and
         36.6.2 may be determined in the future to be  inappropriate  and shall,
         at the request of any Participant, make a good faith effort to evaluate
         and, if appropriate, revise said limit.

         37.0     ARBITRATION:

                  37.1 If a dispute  between  or among  any of the  Participants
         (which  term,  for  purposes  of this  Section  37,  shall be deemed to
         include the Operating  Agent) should arise in relation to any aspect of
         the San Juan Project, any Participant(s) may call for submission of the
         dispute to  arbitration,  which  call shall be binding  upon all of the
         other affected Participant(s).

                  37.2 The  Participant(s)  calling for  arbitration  shall give
         written notice to all other Participants,  setting forth in such notice
         in adequate detail the entity(ies)  against whom relief is sought,  the
         nature of the dispute,  the amount or amounts, if any, involved in such
         dispute, and the remedy sought by such arbitration proceedings.  Within
         twenty (20) days after receipt of such notice, any other Participant(s)
         involved may, by written response to the first Participant(s),  as well
         as the other  Participant(s),  submit its or their own statement of the
         matter at issue and set forth in  adequate  detail  additional  related
         matters  or issues to be  arbitrated.  Thereafter,  the  Participant(s)
         first  submitting its or their notice of the matter at issue shall have
         ten (10) days in which to submit a written rebuttal  statement,  copies
         of which shall be provided to all other Participants.

                  37.3  Within  ten (10)  days  following  delivery  of the last
         written   submittal    pursuant   to   Section   37.2,   the   affected
         Participant(s), acting through their respective representatives,  shall
         meet  for  the  purpose  of  selecting   arbitrators.   Each   affected
         Participant,  or group of  Participants,  representing  one side of the
         dispute,  shall  designate an arbitrator.  The  arbitrators so selected
         shall meet within twenty (20) days following  their selection and shall
         select  additional  arbitrator(s),   the  number  of  which  additional
         arbitrators  shall be one (1) less than the total number of arbitrators
         selected by the affected  Participants.  If the arbitrators selected by
         the affected  Participants,  as herein  provided,  shall fail to select
         such additional  arbitrator(s) within said twenty (20) day period, then
         the arbitrators shall request from the American Arbitration Association




                                      115
<PAGE>

         (or similar organization if the American Arbitration Association should
         not  exist at the time) a list of  arbitrators  who are  qualified  and
         eligible to serve as hereinafter provided.  The arbitrators selected by
         the affected Participants shall take turns striking names from the list
         of arbitrators furnished by the American Arbitration  Association,  and
         the  last  name(s)  remaining  on said  list  shall  be the  additional
         arbitrator(s). All arbitrators shall be persons skilled and experienced
         in the field which gives rise to the  dispute,  and no person  shall be
         eligible for appointment as an arbitrator who is an officer or employee
         of any of the Participants to the dispute or is otherwise interested in
         the matter to be arbitrated.

                  37.4  Except  as  otherwise  provided  in this  Section  37 or
         otherwise  agreed by the  Participants to the dispute,  the arbitration
         shall  be  governed  by  the  rules  and   practices  of  the  American
         Arbitration   Association   (or  rules  and   practices  of  a  similar
         organization if the American  Arbitration  Association should not exist
         at that time) from time to time in force, except that if such rules and
         practices,  as modified herein, shall conflict with New Mexico Rules of
         Civil Procedure or any other provisions of New Mexico law then in force
         which are specifically applicable to arbitration proceedings,  such New
         Mexico laws shall govern.

                  37.5  Included  in  the  issues  which  may  be  submitted  to
         arbitration  pursuant  to this  Section 37 is the issue of whether  the
         right to arbitrate a particular  dispute is permitted under the Project
         Agreements.

                  37.6 The  arbitrators  shall hear  evidence  submitted  by the
         respective Participants or group or groups of Participants and may call
         for  additional  information,  which  additional  information  shall be
         furnished  by the party  having  such  information.  The  decision of a
         majority of the arbitrators  shall be binding upon all the Participants
         and shall be based on the provisions of the Project  Agreements and New
         Mexico law.



                                      116
<PAGE>

                  37.7  This  agreement  to  arbitrate   shall  be  specifically
         enforceable and the award of the arbitrators shall be final and binding
         upon the  Participants  to the extent provided by the laws of the State
         of New  Mexico.  Any  award  may be filed  with the  clerk of any court
         having  jurisdiction  over the Participants or any of them against whom
         the award is rendered, and, upon such filing, such award, to the extent
         permitted by the laws of the jurisdiction in which said award is filed,
         shall  be  specifically  enforceable  or  shall  form  the  basis  of a
         declaratory judgment or other similar relief.

                  37.8  Each  Participant  or  group  of  Participants  shall be
         responsible  for the fees and  expenses of the  arbitrator  selected by
         that Participant or group of  Participants,  unless the decision of the
         arbitrators  shall  specify some other  apportionment  of such fees and
         expenses.  The fees and  expenses of the neutral  arbitrators  shall be
         shared among the affected Participants equally,  unless the decision of
         the arbitrators shall specify some other apportionment of such fees and
         expenses.  All other expenses and costs of the  arbitration,  including
         attorney fees, shall be borne by the Participant incurring the same.

                  37.9 In the event  that any  Participant(s)  shall  attempt to
         institute or to carry out the provisions  herein set forth in regard to
         arbitration,  and such  Participant(s)  shall  not be able to  obtain a
         valid and enforceable  arbitration decree, such Participant(s) shall be
         entitled to seek legal remedies in a court having  jurisdiction  in the
         premises,   and  the   provisions  in  this  Section  37  referring  to
         arbitration   decisions  shall  then  be  deemed  applicable  to  final
         decisions of such court.

                                    PART VIII

                          RETIREMENT AND RECONSTRUCTION

         38.0     DESTRUCTION, DAMAGE OR CONDEMNATION OF A UNIT:

                  38.1 If all, or  substantially  all,  of a Unit is  destroyed,
         damaged or condemned,  then the Participants with Participation  Shares
         in that Unit by unanimous  agreement may elect to repair or reconstruct
         the damaged, destroyed or condemned Unit in such a manner as to restore
         the Unit to  substantially  the same  general  character  or use as the
         original,  or to such other  character or use as the  Participants  may
         then mutually  agree.  In the event of such  election,  it shall be the
         obligation of the  Participants  to pay for the costs of such repair or
         reconstruction  in  accordance  with the  Participation  Shares  of the
         respective Participants in such Unit, and, upon completion thereof, the
         Participants' rights, titles and interests therein shall be as provided
         in this Agreement.

                  38.2  Failure to reach  unanimous  agreement  as  provided  in
         Section  38.1  shall be  deemed  to be an  election  not to  repair  or
         reconstruct  the damaged,  destroyed or condemned  Unit, in which event
         the proceeds from any insurance or from any award shall be  distributed
         to the Participants in accordance with their  respective  Participation
         Shares in such Unit. The facilities not destroyed, damaged or condemned
         shall be  disposed  of by the  Participants  in a manner to be mutually
         agreed  upon,  and  the  proceeds  from  such   disposition   shall  be
         distributed  in  accordance  with  the  Participation   Shares  of  the
         respective  Participants in such Unit. Nothing in this section shall be
         deemed to preclude any Participant or group of Participants in the Unit
         from agreeing to repair,  reconstruct or replace the damaged, destroyed
         or condemned Unit.


                                      118
<PAGE>

                  38.3 In the event that less than  substantially  all of a Unit
         is destroyed,  damaged or condemned, then it shall be the obligation of
         the Participants having a Participation Share in such Unit to repair or
         reconstruct such Unit. Each  Participant  shall be obligated to pay its
         proportionate  share of the costs of such repair or  reconstruction  in
         accordance with Section 6.2.

                  38.4 In the event that any common equipment and/or facility is
         destroyed, damaged or condemned, then it shall be the obligation of the
         Participants  having a  Participation  Share in such  common  equipment
         and/or  facilities to repair or reconstruct such damaged,  destroyed or
         condemned  equipment  and/or  facilities.  Each  Participant  shall  be
         obligated to pay its proportionate share of the costs of such repair or
         reconstruction in accordance with Section 6.2.

         39.0     RIGHTS OF PARTICIPANTS UPON TERMINATION:

                  39.1 In the  event the  Participants  by  unanimous  agreement
         abandon,  retire or otherwise terminate or suspend operation of the San
         Juan Project prior to the termination of this Agreement, the facilities
         forming the San Juan Project  shall be disposed of by the  Participants
         in a manner to be  unanimously  agreed upon and the proceeds  from such
         disposition shall be distributed to the Participants in accordance with
         their respective Participation Shares.

         40.0     DECOMMISSIONING OF THE PROJECT:

                  40.1  The  Participants  acknowledge  the  appropriateness  of
         incorporating  in a future  amendment to this Agreement,  or in another
         appropriate  contractual  instrument,   provisions  which  address  the
         decommissioning of the San Juan Project and/or of one or more Units. It
         is recognized,  however,  that the resolution of issues associated with
         San Juan Project  decommissioning  will require  protracted  study. The
         Participants  therefore  agree to establish a task force or other forum
         for the careful and deliberate  consideration of decommissioning issues
         so that these issues may be addressed and resolved in a timely  manner.
         The Operating Agent shall propose to the Participants a methodology and
         a schedule for addressing decommissioning issues.

         Participants  are  intended to be several and not joint or  collective,
         and  nothing  herein  contained  shall ever be  construed  to create an

         its express written consent, except as expressly provided herein.

                  41.2 The  Participants  hereby  elect to be excluded  from the
         application  of  Subchapter  "K" of  Chapter 1 of  Subtitle  "A" of the

         thereof, may be applicable to the Participants hereunder.

         43.0      OTHER PROVISIONS:

                  43.1  Each  Participant   agrees,   upon  request  by  another
         Participant,  to  make,  execute  and  deliver  any and  all  documents
         reasonably required to implement the terms of this Agreement.

                  43.2 No  Participant  shall be  considered to be in default in
         the  performance  of any  of  the  obligations  hereunder  (other  than
         obligations  of a Participant  to pay costs and expenses) if failure of
         performance   shall  be  due  to   uncontrollable   forces.   The  term
         "uncontrollable  forces" shall mean any cause beyond the control of the
         Participant   affected,   including  but  not  limited  to  failure  of
         facilities, flood, earthquake,  storm, fire, lightning,  epidemic, war,
         riot, civil disturbance,  labor dispute,  sabotage,  restraint by court
         order or  public  authority,  or  failure  to  obtain  approval  from a
         necessary governmental authority which by exercise of due diligence and
         foresight such  Participant  could not reasonably have been expected to
         avoid  and which by  exercise  of due  diligence  it shall be unable to
         overcome.  Nothing contained herein shall be construed so as to require
         a Participant  to settle any strike or labor dispute in which it may be
         involved.  Any Participant rendered unable to fulfill any obligation by
         reason of uncontrollable  forces shall exercise due diligence to remove
         such inability with all reasonable dispatch.

                  43.3 The captions and headings appearing in this Agreement are
         inserted merely to facilitate  reference and shall have no bearing upon
         the interpretation of the provisions hereof.

                  43.4 This Agreement is made under and shall be governed by the
         laws of the State of New Mexico.

                  43.5 The covenants and  obligations set forth and contained in
         this  Agreement  are to be  deemed  to be  independent  covenants,  not
         dependent covenants, and the obligation of a Participant to perform all
         of the  obligations and covenants to be by it kept and performed is not
         conditioned  on the  performance  by another  Participant of all of the
         covenants and obligations to be kept and performed by it.

                  43.6 In the event that any of the terms or  conditions of this
         Agreement,  or the  application  of any such term or  condition  to any
         person or  circumstance,  shall be held  invalid  by any  court  having
         jurisdiction in the premises, the remainder of this Agreement,  and the
         application  of such terms or  conditions  to persons or  circumstances
         other than those as to which it is held invalid,  shall not be affected
         thereby.

                  43.7 All  costs or  expenses,  including  all  taxes  that the
         Operating Agent is required to pay (but not specifically referred to in
         other sections of this Agreement),  which are incurred by the Operating
         Agent in connection with the performance of its obligations  under this
         Agreement and which are not specifically  allocated to the Participants
         in accordance  with this Agreement  shall be equitably  allocated among
         the  Participants  in a manner to be  established  by the  Coordination
         Committee.

                  43.8 Should a change in circumstances,  economic  factors,  or
         basic  technology  occur which  results or may result in a  substantial
         increase  or decrease  in the  benefits  to or  expenses  incurred by a
         Participant,  including the Operating Agent,  which such change was not
         within the reasonable  contemplation of the Participants at the time of
         the  execution  of this  Agreement,  the  Participants,  including  the
         Operating  Agent,  shall  negotiate  in good  faith  in  order  that an
         appropriate and equitable adjustment shall be made in the reimbursement
         of the  Operating  Agent and in the  allocation  of expenses  among the
         Participants.  Such  adjustment  shall be fair and equitable as to both
         the Operating Agent and the other Participants.

                  43.9 This  Agreement  shall be subject to filing with,  and to
         such changes or  modifications as may from time to time be directed by,
         competent  regulatory  authority,  if  any,  in  the  exercise  of  its
         jurisdiction.

                  43.10 It is the intent of the  Participants  in executing this
         Agreement  to set out in one  instrument  the entire  agreement  of the
         Participants  with  respect to the subject  matter  hereof,  and on the
         effective date hereof to explicitly  amend and restate,  and to replace
         in their entirely, the Co-Tenancy Agreement and the Operating Agreement
         and all  modifications  thereto.  Accordingly,  on the  effective  date
         hereof,  the  Co-Tenancy  Agreement and the Operating  Agreement are no
         longer in force and effect  except as  incorporated  herein;  provided,
         however,  that the interim coal billing arrangements  reflected in side
         agreements shall continue in effect through their stated term.

                  43.11 The  execution  of this  Agreement  shall not affect any
         rights or  obligations  of the  Participants  which shall have  accrued
         prior to the effective date of this Agreement, including any obligation
         to pay money or take other  actions in accordance  with the  Co-Tenancy
         Agreement and the Operating Agreement or any other agreement.

44.0     EXECUTION IN COUNTERPARTS:

         44.1 This Agreement may be executed in any number of counterparts,  and
each  executed  counterpart  shall have the same force and effect as an original
instrument as if all the Participants to the aggregated  counterparts had signed
the same  instrument.  Any signature page of this Agreement may be detached from
any  counterpart  thereof  without  impairing the legal effect of any signatures
thereon and may be attached to any other counterpart of this Agreement identical
in form thereto but having attached to it one or more additional pages.

45.0     AMENDMENTS:

         45.1 Except as provided in Section 45.2,  this Agreement may be amended
only by written  instrument  executed by all of the  Participants  with the same
formality as this Agreement.

         45.2 The Coordination  Committee,  by unanimous vote, may amend any one
or more of the  exhibits  attached to this  Agreement.  In the event of any such
action  by the  Coordination  Committee,  a copy of the  new  exhibit  shall  be
attached to this Agreement to replace the old or superseded exhibit, without the
necessity of formally amending this Agreement.  Any such action shall not affect
other provisions of this Agreement, including other exhibits thereto.

                             Exhibit VI-Attachment A


       A&G RATIO APPLICABLE TO OPERATION AND MAINTENANCE FOR THE SAN JUAN
       ------------------------------------------------------------------
                           GENERATING STATION ("SJGS")
                           ---------------------------

         The Operating Agent determines, in accordance with Accounting Practice,
         the appropriate A&G expense incurred for the benefit of the SJGS and to
         be billed to the SJGS as follows:

         1. A&G  expenses  directly  chargeable  by  on-site  San  Juan  Project
         employees as set forth in Section 22.2.2;

         2. A&G expenses directly  chargeable by A&G related departments located
         off-site as set forth in Section 22.2.2; and

         3. Indirect A&G expenses included in the development of the A&G ratio.

         Except as set forth in Section 22.0,  individuals located off-site must
         either charge their time and expenses direct to the SJGS or be included
         in the A&G pool in the development of the A&G Ratio. Costs incurred for
         the same purpose  must be either all charged  direct to the SJGS or all
         be included in the A&G pool,  e.g.,  all staff persons  within the same
         department must either charge direct to the SJGS or to the A&G pool.

A.       The Operating  Agent conducts an A&G study every three years.  However,
         periodic   reviews  will  be  performed  to  determine  if  significant
         organizational  changes have  occurred  that may require the  Operating
         Agent to  conduct an A&G study on a basis  more  frequently  than three
         years.  This study  determines the  appropriate  amount of indirect A&G
         expense to utilize in the development of the A&G Ratio described below.

         The FERC A&G accounts  included in the A&G study are:  920,  921,  923,
         930.2, 931 and 935.

         Background
         ----------

         The  responsibility  for the SJGS resides in the Operating Agent's Bulk
         Power Business Unit. The A&G expenses charged to this Business Unit are
         derived from two areas.  The first  component is an  allocation  of A&G
         expenses from the Operating  Agent's Corporate Office to the Bulk Power
         Business  Unit.   These   allocations   are  based  on   pre-determined
         methodologies.  The second component of costs are A&G expenses that are
         directly  charged  to the  Bulk  Power  Business  Unit.  Note:  Any A&G
         expenses   charged   directly  to  the  SJGS  are  excluded   from  the
         determination of the A&G Ratio and are not subject to the A&G Ratio.


                                   Exh. VI - 1
<PAGE>

         A  questionnaire  is sent to all managers  that have A&G charges to the
         Bulk Power  Business  Unit to determine  what  percentage  of their A&G
         expenses should be included in the development of the A&G Ratio.

         The percentages derived from the questionnaires are then applied to the
         actual A&G  amounts  charged to the Bulk  Power  Business  Unit for the
         study year. Amounts are split between labor and other.

B.       Labor Ratios for Payroll Taxes (FERC Account 408), Injuries and Damages
         (FERC  Account  925) and Pension and Benefits  (FERC  Account 926) (See
         Exhibit VI  Attachments B, C and D) are applied to the labor portion of
         the A&G determined above.

C.       Other  costs  included  in  the   development  of  the  A&G  Ratio  are
         Depreciation  of General Plant (FERC Account 403),  Property  Insurance
         (FERC  Account  924) and  Property  Taxes  (FERC  Account  408) for the
         Operating Agent's headquarters buildings and energy management facility
         and  Amortization  of Computer  Software (FERC Account 404) for certain
         software applications that provide benefit to the SJGS.

         The portion of the costs related to the Operating Agent's  headquarters
         buildings  included in the  development of the A&G Ratio are derived by
         applying certain ratios obtained from the A&G study questionnaires. The
         costs  included  in the A&G  Ratio  for the  Operating  Agent's  energy
         management facility are based on the number of MW of SJGS capacity as a
         percentage  of the  Operating  Agent's total  generating  capacity.  In
         addition,  ratios  for  determining  the  amount of  software  costs to
         include  in  the  A&G  Ratio  are  based  on  the   specific   software
         application.  For  example,  if the  Operating  Agent  installed  a new
         payroll  system,  the  amount of costs for this  system  that  would be
         included in the A&G Ratio  calculation  would be based on the number of
         employees  at the SJGS as a  percent  of the  Operating  Agent's  total
         employees.   The  Operating   Agent  reviews  each  specific   software
         application  to  determine  the method for  assigning  the  appropriate
         amount of costs to be included in the A&G Ratio calculation.

The A&G ratio shall be applied to the following SJGS costs:

         1) Labor charged to the operation and maintenance  expenses included in
            Sections 22.2.1, 22.3, 22.4, 22.5 and 23.3.3 of the San Juan Project
            Participation  Agreement.  Such labor  dollars  are  utilized as the
            denominator in the calculation of the A&G Ratio described below.

The  A&G  Ratio  shall  be  derived  annually  based  on  the  preceding  year's
experience,  as set forth herein unless otherwise agreed to by the participants.
The A&G Ratio will be adjusted to actuals at year-end and the adjustment will be
used in the computation of the A&G Ratio for the following year.

                                 A&G Ratio = A/B

        CAPITALIZED A&G RATIO APPLICABLE TO CAPITAL PROJECTS FOR THE SAN
        ----------------------------------------------------------------
                        JUAN GENERATING STATION ("SJGS")
                        --------------------------------

         The Operating Agent determines the appropriate A&G expense incurred for
         the benefit of the SJGS and to be billed to the SJGS as follows:

A.       The Operating  Agent conducts an A&G study every three years.  However,
         periodic   reviews  will  be  performed  to  determine  if  significant
         organizational  changes have  occurred  that may require the  Operating
         Agent to  conduct an A&G study on a basis  more  frequently  than three
         years.  This study  determines the  appropriate  amount of indirect A&G
         expense to  utilize in the  development  of the  Capitalized  A&G Ratio
         described below.

         The FERC A&G accounts  included in the A&G study are:  920,  921,  923,
         930.2, 931 and 935.

         Background
         ----------

         The  responsibility  for the SJGS resides in the Operating Agent's Bulk
         Power Business Unit. The A&G expenses charged to this Business Unit are
         derived from two areas.  The first  component is an  allocation  of A&G
         expenses from the Operating  Agent's Corporate Office to the Bulk Power
         Business  Unit.   These   allocations   are  based  on   pre-determined
         methodologies.  The second component of costs are A&G expenses that are
         directly  charged  to the  Bulk  Power  Business  Unit.  Note:  Any A&G
         expenses   charged   directly  to  the  SJGS  are  excluded   from  the
         determination  of the Capitalized A&G Ratio. Two Capitalized A&G Ratios
         are calculated,  one for major construction  projects (Projects greater
         than  $10,000,000) and one for minor  construction  projects  (Projects
         less than $10,000,000).

         A  questionnaire  is sent to all managers  that have A&G charges to the
         Bulk Power  Business  Unit to determine  what  percentage  of their A&G
         expenses are  capital-related and should be included in the development
         of the  Capitalized  A&G Ratios.  Amounts are split  between  labor and
         other.

B.       Labor Ratios for Payroll Taxes (FERC Account 408), Injuries and Damages
         (FERC  Account  925) and Pension and Benefits  (FERC  Account 926) (see
         Exhibit VI  Attachments B, C and D) are applied to the labor portion of
         the A&G determined above.

The  Capitalized  A&G Ratios,  shall be applied to all SJGS  construction  costs
except for long-term leased  transportation and motorized  equipment.  The total
amount of these  construction  dollars are  utilized as the  denominator  in the
calculation of the A&G Ratio described below.

                                   Exh. VI - 7
<PAGE>

                           Capitalized A&G Ratio = A/B

Where    A =   Administrative  and  general  expense  chargeable  to  FERC
               Accounts 920,  921,  923,  930.2,  931 and 935,  including  Labor
               Ratios for Payroll Taxes (FERC Account 408), Injuries and Damages
               (FERC Account 925) and Pension and Benefits (FERC Account 926) as
               categorized  separately  in the A&G  questionnaire  for major and
               minor construction expenditures for the study period.

         B =   Total SJGS capital  project amounts for the Bulk Power Business
               Unit as categorized between major and minor construction projects
               for the study period chargeable to FERC Accounts 107 and 108.


Note:    Any  modifications to the methodology  utilized for calculating the A&G
         Ratio  described  above  shall be  developed  by the San Juan  Auditing
         Committee and approved by the San Juan Coordination Committee.

                 Proportional Adjustment of Voting Requirements
                 ----------------------------------------------
       in Case of a Default and Suspension of the Rights of a Participant
       ------------------------------------------------------------------
                       to Vote Pursuant to Section 35.4.1.
                       -----------------------------------

        Example Calculation Based on Hypothetical Ownership Percentages:


In the following table, Participant D with Participation Shares in Units 3 and 4
is assumed to be the defaulting Participant. Participation Shares for Voting and
Number of  Participants  for  Voting are shown  under  original  or  pre-default
conditions and are then adjusted as provided in Sections 18.4,  19.4,  20.5, and
21.4 after the right of  Participant D to vote is suspended  pursuant to Section
35.4.1.

Participation Shares for voting pursuant to Sections 18.4.1(a),  18.4.2(a),  and
18.4.3(a) are adjusted as follows:

         For Units:

                  The      Adjusted  Participation  Share  for a  Participant  =
                           (That Participant's  Participation Share)/(The sum of
                           the  Participation   Shares  of  all   non-defaulting
                           Participants in the affected Unit)

         For Common Facilities:

                  Adjustments related to common facilities shall be proportional
                           to any differing  Participation Shares between Units.
                           The above  formula  would be applied to each Unit and
                           then summed and normalized over the applicable common
                           facilities.  Because  San Juan  Units are of  unequal
                           ratings,  the normalization  will be in proportion to
                           each Unit's rating rather than the even  fractions in
                           the example below where equally sized units were used
                           for simplicity.

The  numbers  of  Participants   used  for  voting  purposes   pursuant  to  the
requirements  of Sections  18.4.1(b),  18.4.2(b),  and 18.4.3(b) are adjusted by
subtracting  the  number of  defaulting  Participants  from the total  number of
Participants voting under those Sections.

                                   STIPULATION
                                   -----------

         The  signatories  to this  Stipulation,  as indicated on the  signature
page, are collectively  referred to herein as the "signatories." The signatories
have  jointly  prepared  and submit this  Stipulation  to the New Mexico  Public
Regulation Commission ("Commission" or "PRC") for approval in this case:

                                   BACKGROUND
                                   ----------

         1. In its Final Order in NMPUC Case No.  2752  issued on  February  13,
1997, the New Mexico Public Utility  Commission  ("PUC")  ordered Public Service
Company of New Mexico ("PNM") to file an electric general rate case using a test
period of the 12 months ending December 31, 1996.

         2. In accordance with  subsequent PUC orders,  on November 3, 1997, PNM
filed  its  Advice   Notice  No.  258  and  its  petition  for  all   approvals,
authorizations and variances  necessary for PNM to implement 13 proposed revised
rates and 14 proposed  new rates and to cancel 3 current  rates.  PNM also filed
its Experimental Incremental Interruptible Power Rate ("EIIPR") Final Report.

<PAGE>

         3.  Subsequently,  the  Commission  suspended  PNM's proposed rates and
appointed Peter E. Springer as Hearing Examiner to preside over hearings in this
case.
         4. After an evidentiary hearing and submission of post-hearing  briefs,
the PUC issued its Final  Order on  November  30,  1998,  from which PNM took an
appeal to the New Mexico Supreme Court in Docket No. 25,513.  On March 15, 1999,
the Court issued its Decision, vacating and annulling the PUC's Final Order and,
thereafter, the Court remanded Case No. 2761 to the PRC "for further proceedings
consistent  and in  conformity  with the  decision  of this  Court  and with the
opinion issued in Cause No. 25,523, State ex rel. Sandel v. PUC."

         5. The PRC entered its Order Establishing Procedures on Remand on April
20, 1999,  finding  that this matter  should be brought to final  resolution  as
expeditiously  as  possible  and that the  signatories  should  be  allowed  the
opportunity  to  reach a  negotiated  settlement  in  order  to  expedite  final
resolution.

         6. By entering into this  Stipulation the  signatories  intend to serve
the public interest by bringing this case to final  resolution as  expeditiously
as possible,  providing immediate  implementation of lower rates and tariffs for
all PNM  customer  classes,  rate  stability  for PNM's  customers  and  revenue
stability for PNM.

         NOW THEREFORE,  in  consideration  of their mutual  promises and of the
benefits they and their respective constituencies will receive, the signatories,
through their  undersigned  authorized  representatives,  stipulate and agree as
follows:

                                       2
<PAGE>


                                 RATE REDUCTION
                                 --------------

         7. PNM  shall  file new  tariffs  which  shall  reduce  its New  Mexico
jurisdictional  1996 test period  annualized  revenues of $504,903,847  filed in
Case No. 2761 by $34,000,000, based on 1996 billing determinants.  These tariffs
shall be effective for all bills rendered on and after July 30, 1999. If a final
order approving this  Stipulation is entered after June 30, 1999 and as a result
PNM is unable to implement the rate reduction agreed to herein by July 30, 1999,
the rate reduction will  nevertheless be effective for all bills rendered on and
after July 30, 1999.  PNM will  implement the rate reduction with the first full
monthly  billing  cycle  which  begins  30 days  after  entry  of a final  order
approving  this  Stipulation  and shall refund or credit to customers any excess
revenues  collected  as a result  of the delay in  implementation  past July 30,
1999.

         8. To comply with ss. 18 of the Electric Utility Industry Restructuring
Act of 1999, Laws of 1999, ch. 294 ("the Act"), PNM shall also file a second set
of new tariffs  which shall  reduce New Mexico  jurisdictional  1996 test period
annualized revenues by an additional $7,409,457 to reflect that local government
franchise fees ("franchise  fees") currently  charged by government  authorities
shall be  collected  from and  stated  as a  separate  line item on the bills of
customers located within the jurisdiction of the government  authority  imposing
the fee.  This second set of tariffs will replace the tariffs  described in P. 7
once  PNM's  customer  billing  system  (Banner)  has been  modified  to reflect
franchise  fees as a separate line item on customers'  bills.  PNM will use best
efforts  in good  faith to  implement  this  second  set of  tariffs  as soon as
possible,  with franchise fees as a separate line item charged only to customers
located within the  jurisdiction of the government  authority  imposing the fee.
But in any event,  PNM will  comply with all  Commission  orders  applicable  to
franchise fees.  Notwithstanding the foregoing language, the signatories to this
Stipulation  expressly  reserve  all  rights  and  remedies  they may have under
Section 18A of the Act.


                                       3
<PAGE>

         9. The annual base rate revenue  reductions  set forth in  paragraphs 7
and 8 will be allocated  among  current rate classes pro rata on a revenue basis
as shown in  Attachments A and B,  respectively  to this  Stipulation.  Specific
tariffs reflected in Attachments C and D, respectively, to this Stipulation show
how the resulting $470,903,847 or $463,494,390 of revenues will be collected.

         10. The  Experimental  Incremental  Interruptible  Power Rate ("EIIPR")
will be continued on a  non-experimental  basis for customers on that rate as of
the  date of the  execution  of this  Stipulation,  will not be  offered  to new
customers, and will be called the Incremental Interruptible Power Rate ("IIPR").
The rates on the IIPR and on the  economic  development  rate riders will not be
reduced.

         11. The signatories agree that Tariff 16, PNM's Special Changes tariff,
should  be  approved  as part of this  Stipulation.  Tariff  16 is  included  in
Attachments C and D to the Stipulation.

                                 RATE STABILITY
                                 --------------

         12.  Except  as  otherwise  provided  in this  Stipulation,  the  rates
stipulated  to herein and PNM's  Street and Private  Area  Lighting  rates shall
continue in effect,  regardless  of any changed  circumstances,  until  customer
choice service is implemented in accordance  with ss. 4 of the Act or January 1,
2003, whichever occurs first.

         13. Under Section  4(A)(1) of the Act customer  choice service is to be
implemented  for  public  post-secondary  educational  institutions  and  public
schools,  residential and small business  customers  before all other customers.
Therefore, the rates for each customer class stipulated to herein will remain in
effect until customer  choice service is implemented  for that class even though
customer choice service may have been previously implemented for another class.


                                       4
<PAGE>
         14. The signatories will not institute on their own motion or encourage
or support another person to seek or initiate any proceeding requesting a change
in PNM's  rates  which would take  effect  prior to  implementation  of customer
choice service under the Act. If at any time after approval of this  Stipulation
any person petitions or otherwise seeks from the Commission a rate case or other
proceeding or the Commission initiates a rate case or other proceeding to review
the  reasonableness of PNM's revenue  requirements and to seek a change in rates
that would become effective prior to  implementation  of customer choice service
under the Act, the  signatories  will state their support for the  provisions of
this  Stipulation  and the  continuation  of the rates  stipulated  herein.  The
signatories  will  support,  and  work in good  faith  and to the  best of their
abilities to meet,  the  timeframes  established  in Section 4(A) of the Act for
implementation  of customer choice service and will not institute or support any
delay in these  timeframes  unless  necessary to maintain  adequate and reliable
service to customers.  This does not preclude the  signatories  from  requesting
extensions  of time,  continuances  or other  appropriate  relief  from  hearing
schedules or other deadlines in PRC proceedings initiated pursuant to the Act.

         15.  Except as  otherwise  provided  in this  Stipulation,  before  the
effective date of customer  choice  service,  the  signatories may make filings,
subject  to  Commission  approval,  that  modify  tariffs,  riders and terms and
conditions of rate  schedules or which propose new tariffs,  riders or terms and
conditions,  so long as such  changes or  additions  do not increase or decrease
base  rates  reflected  in the  rate  schedules  implemented  pursuant  to  this
Stipulation  or  increase  or  decrease  revenues  to PNM based on 1996  billing
determinants.  However,  this Stipulation  shall not preclude PNM from proposing
decreases in rates or revenues.


                                       5
<PAGE>

         16.  Notwithstanding  any provision herein to the contrary,  before the
effective date of customer  choice  service,  the  signatories may make filings,
subject to Commission approval,  that modify or propose new tariffs,  riders and
terms and conditions of rate schedules if any governmental authority imposes (a)
a new franchise fee or a change in an existing franchise fee or (b) the Case No.
2787 renewable energy surcharge.  In addition,  PNM may seek approval of tariffs
to recover from governmental authorities increased costs of a siting, permitting
or construction  requirement that mandates the  extraordinary  undergrounding of
distribution  facilities not recovered under PNM's line extension  policy or the
undergrounding  of  transmission  facilities;  provided  however,  a requirement
mandating  undergrounding  necessary  to comply  with  state or  federal  rules,
regulations  or laws shall not be included in such request to recover  increased
costs from governmental  authorities.  The signatories will not oppose a request
by PNM for a Commission  hearing or rulemaking on the recovery from governmental
authorities  of  increased  costs  of  the   extraordinary   undergrounding   of
distribution  facilities not recovered under PNM's line extension  policy or the
undergrounding of transmission facilities required by such authorities.

         17.  Nothing  herein  shall  affect the  operation of NMPUC Rule 330 or
PNM's Tax Adjustment Clause or PNM's Palo Verde  Refinancing  Credit approved in
Case No. 2837 which is stated as a separate line item on customers' bills.

         18. The  signatories  acknowledge  that this  agreement to reduce rates
constitutes  valuable  consideration  which the signatories  have given based on
their  expectation  that base rates will not be changed  until  customer  choice
service  is  implemented  or  January  1,  2003,  whichever  occurs  first.  The
signatories  further  acknowledge that they have agreed to the rate reduction in
reliance on and in exchange  for the other  signatories'  promise that they will
not support  docketing  any  proceeding  to review the  reasonableness  of PNM's
rates,  to seek a change in rates prior to  implementation  of  customer  choice
service,  or support a delay in the  implementation  of customer  choice service
beyond  the dates  set forth in  Section  4(A) of the Act,  except as  otherwise
provided in this Stipulation.

                               GENERAL PROVISIONS
                               ------------------

         19. The signatories  will use their best efforts to obtain  expeditious
implementation  of  this  Stipulation  by  the  entry  of an  appropriate  final
Commission  order. This Stipulation  assumes the legality and  enforceability of
the  rates and  agreements  set forth in this  Stipulation.  Should  any rate or
agreement  set forth in this  Stipulation  be rejected,  modified or directly or
indirectly rendered inoperable by Commission or Court decision,  any party shall
have the  right,  by  filing a notice of  withdrawal  with the PRC  within  five
working days, to withdraw from this  Stipulation and render this  Stipulation of
no further force and effect, in which case the signatories shall attempt in good
faith to negotiate an appropriate substitute rate or agreement.

         20. Under  Commission Rule 531 adopted by the PUC in Case No. 2816, PNM
is  required,  for  informational  purposes,  to  functionalize  the rates which
implement the revenue  reduction  agreed to herein.  The signatories  agree that
neither the  methodology  used to  functionalize  PNM's rates nor the  resulting
functionalized  rates after the rate  reduction to comply with  Commission  Rule
531, shall in any way bind the signatories,  constitute an admission or have any
precedential effect in any proceeding, including,  specifically, any proceedings
and determinations required under the Act.


                                       7
<PAGE>

         21. The rate design,  rate design  method,  the  allocation  of revenue
requirements and the allocation method for setting revenue  requirements  agreed
to in this  Stipulation  reflect  various  compromises  of the  positions of the
signatories in this case for  settlement  purposes only and shall not constitute
an  admission  of any kind or otherwise  bind any  signatory  or  establish  any
precedent or  presumption  in any other  proceeding,  including any  proceedings
required by the Act.

         22. This Stipulation shall not prejudice, bind, or affect any party, or
be viewed as an admission,  except to the extent  necessary to give effect to or
enforce the terms of this  Stipulation or unless otherwise  specifically  stated
herein. In the event this Stipulation is not approved by the Commission, nothing
in this  Stipulation  or  negotiations  leading  up to its  execution  shall  be
construed as an admission of a signatory's  position on any issue nor be used or
offered into evidence by any signatory in this or any other proceeding.

         23. Neither this  Stipulation  nor changes or deletions in the proposed
4000B tariff to the section entitled,  "Service With A Contract Demand of 10,000
KW Or More:" shall  prejudice,  bind,  or serve as an admission by any signatory
regarding  the historic  application/availability  of PNM's  current  tariffs to
specific     customers    or    regarding     the    provision    of    electric
generation/transmission  to the United States Executive  Agencies  facilities by
the Western Area Power Administration.

         24. In its  transition  plan filed  pursuant to the Act,  PNM agrees to
propose methods to address the situation of customers  which,  after open access
pursuant to the Act, may not have genuine access to markets and suppliers beyond
PNM's  system,  and as such  could be  exposed to  excessive  market  power of a
competitive power supplier.

described  on  Exhibit  2.1  attached  hereto  and on  the  basis  of  financial
information  that is  current  as of the date on which  such  revised  estimated
Purchase Price is established,  and such revised  estimate will be the basis for
the payment of the Purchase  Price on the Closing Date. As soon as possible (but
no more than forty-five days) after the Closing Date, the parties will negotiate
in good faith to agree to and establish a final Purchase Price,  and within five
(5) business days after such final Purchase Price is established, one party will
make to the other a payment to reconcile the difference  between the provisional
Purchase Price (revised as hereinbefore described) and the final Purchase Price.
In the event the parties  are unable to agree on a final  Purchase  Price,  such
dispute will be submitted to arbitration pursuant to Section 13.3 hereof.

         2.2 Allocation of Purchase Price. The Purchase Price shall be allocated
among the Assets in such manner as may be agreed  upon by the  parties  prior to
the Closing in  accordance  with Section  1060 of the  Internal  Revenue Code of
1986, as amended (the "Code");  provided,  however,  that if the parties  cannot
mutually  agree upon such  allocation,  such  allocation  shall be  conclusively
determined  by an  independent  appraiser  selected  by the  parties,  who shall
prepare such appraisal in accordance  with Section 1060 of the Code. The parties
agree that any tax filings that they may make in relation to the Assets shall be
consistent with such allocations.

                           and

                           Governmental   Authority  of  any  legally   required

                           a Material Adverse Effect on the Assets.

         (viii)   Maintenance of the Assets.  Seller and Plains have  maintained
                  the Assets in  reasonable  operating  condition and repair and
                  the  Assets  are   adequate  to  perform   normal   operations
                  consistent  with Plains'  recent  practices,  except where the
                  failure to maintain  would not have a Material  Adverse Effect
                  with respect to the Assets.

         (ix)     Contracts. Seller and Plains have provided Buyer with complete
                  copies  of the  Contracts  and  all  amendments  thereto.  The

                  Contract  has prepaid more than 30 days in advance any amounts
                  due thereunder. Seller has not waived its remedies for default
                  by, or  expressly  waived any other  rights  against,  a third
                  party  under any  Contract.  Seller and  Plains  have made all
                  payments due thereunder,  if any, except those being contested
                  in good  faith,  and  have  performed  all of  their  material
                  obligations under such Contracts,  except for such failures to
                  make  payments or perform  obligations  which would not have a
                  Material  Adverse  Effect with  respect to the Assets.  To the
                  knowledge of Seller and Plains, there are no written proposals
                  or threats by third parties to cancel, revise or fail to renew
                  any   Contract  or  fail  to  renew,   cancel  or  revise  any
                  right-of-way or easement.

         (x)      Title to Property.  Plains has, and on the Closing Date Seller
                  will have,  good and marketable  title to the Assets,  in each
                  case free and clear of all mortgages, liens, charges, security
                  interests, or other encumbrances except Permitted Encumbrances
                  (as herein  defined).  To the knowledge of Seller,  no adverse
                  title  claims are pending or  threatened  with  respect to any
                  portion of the  Assets and Seller  owns its rights in the same
                  free and  clear of all  mortgages,  liens,  charges,  security
                  interests or other encumbrances except Permitted Encumbrances.
                  For the purposes of this Agreement,  "Encumbrances" shall mean
                  all  liens,  mortgages,  pledges,  claims,  charges,  security
                  interests   or   other   encumbrances,    including,   without
                  limitation,  any leases, subleases,  rights-of-way,  licenses,

                  property  affected  thereby,  (c) water  rights  and claims to
                  water  which do not  materially  adversely  affect  the value,

                  the  deferred   purchase  price  of  property)  which  do  not
                  materially adversely affect the value, condition or usefulness
                  of the property affected  thereby.  As of the date of delivery

         (xvii)   Existing Arrangements. Exhibit 5.1(xvii) attached hereto lists
                  the   existing   contractual   arrangements   (the   "Existing

         (i)      Material  Discrepancies  or  Breaches.  Buyer  shall  not have
                  discovered any material error, misstatement or omission in the

                  on  behalf  of   Plains)  or  any   material   breach  in  the
                  undertakings  and  agreements  by Seller  (for  itself  and on
                  behalf of Plains) as set forth in this Agreement.

                  Schedule discloses a matter that would have a Material Adverse
                  Effect with respect to one or more  individual  Assets,  Buyer
                  and Seller  shall use their best  efforts  to  negotiate  such
                  adjustments  as may be  necessary  to carry  out the  original
                  intent of the parties with respect to the remaining Assets not

         (iii)    Performance  of  Conditions.  Seller (and,  where  applicable,
                  Plains)  shall  have  performed  and  complied  with all other
                  agreements  and  conditions  required by this  Agreement to be

                  party,  which are necessary or required to be obtained by such
                  party in order to consummate the transaction, except where the
                  failure  to  obtain  such  approval,  authorization,  consent,
                  license,  permit or acceptance  will not interfere  materially
                  with the consummation of the transaction.

         (v)      Merger.  The  closing  of the  Merger  under  the  Transaction
                  Agreement shall have occurred.

         (vi)     Operations Agreements. The parties shall have entered into the

                  an  arbitrator of its choice within twenty (20) days after its
                  receipt  of the  notice  of  arbitration.  The  parties  shall
                  jointly select and appoint the third arbitrator,  who shall be
                  Chairman  of the Board  (the  "Chairman"),  and shall  jointly
                  determine the fee that each arbitrator  shall receive,  within
                  thirty  (30) days after the  notified  party's  receipt of the
                  notice of  arbitration.  If the parties cannot reach agreement
                  on a Chairman and/or fee, or if any party fails to appoint its
                  party-appointed  arbitrator within the prescribed  period, the
                  missing  arbitrator(s)  and/or  fee shall be  selected  by the
                  Phoenix,  Arizona  office of the AAA pursuant to the selection
                  process  set  forth  in the  Rules  as in  effect  on the date
                  hereof,  provided that all potential  arbitrators submitted to
                  the parties must be chosen from AAA's Large Complex Case Panel
                  or from a panel of the Center for Public Resources and further
                  provided  that  any fee  established  by AAA must  conform  to
                  Section 13.3(vii) below. If an arbitrator should die, withdraw
                  or otherwise become incapable of serving,  a replacement shall
                  be selected  and  appointed  in a like manner as the  original
                  arbitrator.  Any arbitrator  appointed hereunder shall certify
                  in writing that he or she is immediately  available to conduct
                  such arbitration. Upon consultation with the other arbitrators
                  and the  parties,  the  Chairman  shall,  within ten (10) days
                  after  appointment,  set dates for the  hearing.  The Chairman
                  shall  preside at all hearings and  executive  sessions of the
                  Board.  All  decisions  of the Board shall be by a majority of
                  the arbitrators, unless the parties agree otherwise.

         (iii)    (a)      The  arbitration  proceedings  shall  be held in
                           Albuquerque,  Bernalillo  County,  New  Mexico,  at a
                           place to be agreed upon by the parties.

                  (b)      A  stenographic  record of the  proceedings  shall be
                           made and supplied to the Board.

                  (c)      Unless the parties agree  otherwise,  the Board shall
                           require   witnesses   to   testify   under   oath  or
                           affirmation.

                  (d)      The  parties  may offer such  evidence as is relevant
                           and  material to the dispute and shall  produce  such
                           additional  evidence as the Board may deem  necessary
                           to the determination of the dispute.

                  (e)      All evidence to be  considered  by the Board shall be
                           offered    at   the    hearing    and    subject   to
                           cross-examination unless the parties agree otherwise.
                           Exhibits shall be admitted into evidence by the Board
                           only upon the  establishment  of a proper  foundation
                           concerning  authenticity,  unless the  parties  agree
                           otherwise.

                  (f)      There  shall be no direct  communication  between any
                           party and any arbitrator  after the third  arbitrator
                           has been appointed and the  arbitrators' fee has been
                           established  except  at  the  hearing  and  at  joint
                           consultations    between   both   parties   and   the
                           arbitrators  on  the  schedule  as  provided  for  in
                           Section 13.3(ii).

                  (g)      Unless the parties agree  otherwise,  the arbitration
                           hearing   (including   any   filing  of  briefs   and
                           submission  of  documents)  shall be closed within 60
                           days of the appointment of the third arbitrator.

         (iv)     The Board shall render its award in writing within thirty (30)
                  days  following  the close of the  hearing.  The  Board  shall
                  render its award  only with  respect  to the  specific  issues
                  submitted by either party,  and shall base its decision solely
                  upon  the  evidence   before  it,   applicable  law  and  this
                  Agreement.

         (v)      Judgment  upon the award may be entered and  execution  had or
                  application may be made for a judicial acceptance of the award
                  and an order of enforcement,  as the case may be, in any court
                  located in Bernalillo County, New Mexico.

         (vi)     The  arbitration  may  proceed in the absence of a party that,
                  after due notice,  fails to be present.  An award shall not be
                  made  solely on the  default of a party,  but the Board  shall
                  require  the party that is present  to submit  such  available
                  evidence as may be  reasonably  required  for the making of an
                  award.

         (vii)    The parties  shall share  equally the cost of the  arbitration
                  proceedings,   including   the  fees  and   expenses   of  the
                  arbitrators  and the  cost of the  stenographic  record.  Each
                  arbitrator  shall be paid an identical  flat fee,  which shall
                  not vary,  irrespective  of the length of service or number of
                  hearings,  and  neither  the AAA nor the Board  shall have any
                  authority  to  authorize  the  payment  of a fee on any  other
                  basis.

         (viii)   All aspects of the arbitration shall be confidential,  and the
                  parties and arbitrators shall maintain the  confidentiality of
                  all information related to the proceedings,  including but not
                  limited to documents  exchanged by the parties,  testimony and
                  other evidence,  briefs and the award,  and shall not disclose
                  the same to any third party.  Upon the motion of either party,
                  and for good cause  shown,  the Board may make any order which
                  justice  requires  to protect a party from the  disclosure  of
                  proprietary,  privileged or confidential business information,
                  including (1) that  hearings be conducted  with no one present
                  except persons designated by the Board, and (2) that exhibits,
                  other  documents  filed with the Board or  transcripts  of the
                  hearing be sealed and not be disclosed  except as specified by
                  the Board.  Notwithstanding the foregoing, each party shall be
                  entitled to disclose such  information  (i) to its affiliates,

                  attorneys,   financial   or  lending   institutions,   outside
                  auditors,  insurers,  and entities  involved in negotiation or
                  bidding for the  acquisition of a party,  its stock or assets,
                  provided  that the person or entity to which such  information
                  is disclosed is obligated to hold it confidential, (ii) as may
                  be required by law or by regulation  or order of  Governmental
                  Authority or by the rules of any stock exchange  applicable to
                  such party or its  affiliates,  or as part of any party's good
                  faith attempt to comply with disclosure  obligations under any
                  of the same,  (iii) as Seller or Buyer may deem  necessary  or
                  desirable  to  disclose  to  the  NMPRC,  the  FERC  or  other
                  regulatory  body, and (iv) as may be necessary or desirable to
                  enforce such party's rights hereunder.

         (ix)     The Board shall not distribute the stenographic  record of the
                  proceedings  to  the  parties  unless  an  action  as  may  be
                  permitted   under  the  Rules  and  the  New  Mexico   Uniform
                  Arbitration Act  challenging  the  arbitration  proceedings is
                  filed no later than sixty (60) days  following the issuance of
                  the award.  If no such action is timely  filed,  all copies of
                  the stenographic record shall be destroyed.

         (x)      ANY CHALLENGE TO ANY REQUEST FOR  ARBITRATION  OR  ARBITRATION
                  PROCEEDING  HEREUNDER  SHALL BE  LITIGATED,  IF AT ALL, IN AND
                  BEFORE A STATE OR FEDERAL COURT LOCATED IN BERNALILLO  COUNTY,
                  NEW MEXICO,  TO THE EXCLUSION OF THE COURTS OF ANY OTHER STATE
                  OR COUNTY.

         (xi)     Any  obligation  to  arbitrate  which is  established  by this
                  Section shall survive any  termination  of this  Agreement for
                  the notice period  stipulated in Section 13.3(ii)  hereof,  it
                  being  understood  and agreed  between  the  parties  that any
                  dispute,  controversy  or claim  arising  out of or related to
                  this Agreement,  or the breach  thereof,  that is not notified
                  within such time-frame shall be deemed conclusively waived.

         13.4  Consents  Not  Obtained.  To the extent  that Seller is unable to
obtain a third party consent to transfer any lease,  Contract or other  interest
constituting a part of the Assets and consequently does not assign,  transfer or
sublease  such  Assets  to Buyer,  Seller  shall,  at  Buyer's  written  request
delivered within a reasonable time after Closing,  use its reasonable efforts to
make all benefits of such non-assigned  interests available to Buyer without any
administrative  cost to Buyer,  but shall not be  obligated to incur any cost or
expense  after the Closing Date with respect to such Assets,  all of which shall
be for the account of Buyer.

         13.5 Navopache  Arrangement.  The parties  recognize that the Navopache
Assets are to be  transferred to Buyer as a result of the selection by Navopache
Electric  Cooperative,  Inc.  ("Navopache") of Buyer as its power supplier.  The
parties also  recognize  that it will be necessary for the RUS to release Plains
from its All-Requirements  Contract with Navopache,  and that Navopache likewise
will need to be released by all  necessary  parties  from such  All-Requirements
Contract.  The parties also recognize that it will be necessary for transmission
agreements  identified  on Exhibit  1.1 (vii) to be  assigned  to Buyer and that
other  transmission  arrangements  will  need  to  be  made  between  Buyer  and
Navopache. Finally, the parties recognize that it will also be necessary for the
FERC to approve the new power supply  contract  between Buyer and Navopache.  In
order to make  provision  for the  supply of power to  Navopache  following  the
effective  date  of  the  Merger  in  the  event  that  all  conditions  to  the
effectiveness  of the new power supply contract between Buyer and Navopache have
not been satisfied on or prior to the effective date of the Merger,  and to make
other  transition  arrangements,  the parties  agree to enter into the Navopache
Transition Agreement identified on Exhibit 4.2 attached hereto.

         13.6 Headquarters  Building.  Buyer shall, if required by Seller, lease
the  Headquarters  Facility to Seller for a period not exceeding sixty (60) days
after the Closing Date, at a nominal fee of Thirty Dollars  ($30.00) per day. In
addition,  Seller  shall  have the right to occupy  mutually-agreed  upon  space
within the Headquarters  Facility for as long as reasonably  required to operate
the electrical  power system and relocate the computers and Supervisory  Control
and Data Acquisition system in a safe and orderly manner. Moreover, Seller shall
have the right to use the outlying  buildings and facilities at the Headquarters
Facility  for a period of 150 days after the Closing  Date until the  operations
and  maintenance  functions  can  be  relocated.   Buyer's  wholesale  marketing
department  will occupy the control center  facilities no later than thirty (30)
days after the Closing Date.

         13.7  Rights-of-Way  Renewals.  Notwithstanding  Section  13.4  hereof,
Seller  will  promptly  reimburse  Buyer  for fifty  percent  (50%) of the costs
incurred by Buyer to obtain the renewal (for a period not to extend beyond 2020)
of  any  rights-of-way  on  the  West  Mesa-Belen   transmission  line  and  the
Ojo-Hernandez-Norton-Algodones-West  Mesa 115-kV  transmission path. Buyer shall
at  all  times  keep  Seller  fully  apprised  of  the  status  of  the  renewal
negotiations and shall consult with Seller with respect to such negotiations. In
return for its  reimbursement  with  respect to the Ojo-West  Mesa  transmission
path, Seller and Buyer agree to use good faith efforts to negotiate an equitable
credit for Seller against Seller's network service charges from Buyer, with such
credit to be agreed  before any request for  reimbursement  with respect to such
path is  made.  Notwithstanding  the  foregoing:  (i) with  respect  to the West
Mesa-Belen  rights-of-way,  any  reimbursements  by Seller  shall be returned to
Seller to the extent Buyer places these costs in its filed transmission  tariff;
and (ii) with respect to the Ojo-West Mesa  rights-of-way,  Buyer shall have the
right, at its sole  discretion,  to fund more than its fifty percent (50%) share
of the costs of the  right-of-way  renewals,  thereby  reducing  or  eliminating
Seller's credit.
