                     NOTES TO CONDENSED FINANCIAL STATEMENTS

1. In the opinion of the Company, the accompanying unaudited condensed financial
statements  contain all adjustments  (consisting of normal  recurring  accruals)
necessary to present fairly the financial position of the Company as of June 30,
1997,  the results of  operations  for the three  months,  six months and twelve
months ended June 30, 1997 and 1996, and the cash flows for the six months ended
June  30,  1997  and  1996.  It is  suggested  that  these  condensed  financial
statements  and notes to condensed  financial  statements be read in conjunction
with the financial  statements and notes to financial statements included in the
1996 10-K.

2.  The  Company's  operations  are  subject  to  seasonal  fluctuations,   with
variations in energy usage by customers occurring from season to season and from
month to month  within a  season,  primarily  as a result  of  changing  weather
conditions.  For this and other  reasons,  the results of operations for interim
periods are not  necessarily  indicative  of the results to be expected  for the
full year.

3. All the  outstanding  shares  of  common  stock of the  Company  are owned by
Pinnacle West.

4. See  "Liquidity  and Capital  Resources" in Part I, Item 2 of this report for
changes in capitalization for the six months ended June 30, 1997.

5. Regulatory Matters

Electric Industry Restructuring

State  The  ACC  has  been   conducting  an  ongoing   investigation   into  the
restructuring  of the  Arizona  electric  industry.  In December  1996,  the ACC
adopted rules that provide a framework for the  introduction  of retail electric
competition.  The ACC has ordered that reliability,  stranded cost recovery, the
phase-in process, and bundled, unbundled and metering services, as well as legal
issues,  will require  additional  consideration  and will be addressed  through
workshops and working groups which will issue  recommendations to the ACC during
1997. The Rules include the following major provisions:

o    The Rules are  intended to apply to virtually  all of the Arizona  electric
     utilities regulated by the ACC, including the Company.

o    Each  affected  utility  would be  required to make  available  at least 20
     percent of its 1995 system  retail peak demand for  competitive  generation
     supply to all customer  classes not later than January 1, 1999; at least 50
     percent not later than  January 1, 2001;  and all of its retail  demand not
     later than January 1, 2003.

                                      -9-

o    Electric  service  providers that obtain a Certificate  of Convenience  and
     Necessity  (CC&N) from the ACC would be allowed to supply,  market,  and/or
     broker specified electric services at retail.  These services would include
     electric generation but exclude electric transmission and distribution.

o    On or before December 31, 1997,  each affected  utility is required to file
     with the ACC proposed  tariffs for bundled  service and unbundled  service.
     Bundled  service  means  electric  service   elements  (i.e.,   generation,
     transmission,  distribution,  and ancillary services) provided as a package
     to consumers within an affected  utility's current service area.  Unbundled
     service means electric service elements provided and priced separately.

o    The Rules indicate that the ACC will allow recovery of unmitigated stranded
     costs.  Stranded costs are the costs of generating plants, other assets and
     contract  commitments that were prudently incurred to serve power customers
     that could go unrecovered if these customers are allowed to use open access
     to move to another  supplier.  Each  affected  utility would be required to
     file with the ACC estimates of unmitigated  stranded  costs.  The ACC would
     then, after hearing and  consideration  of various  factors,  determine the
     magnitude  of  stranded  cost  and   appropriate   stranded  cost  recovery
     mechanisms and charges.

The  Company  continues  to focus on working  with the ACC to bring  competitive
benefits  to Arizona  but  believes  that  certain  provisions  of the Rules are
deficient.  In February  1997, a lawsuit was filed by the Company to protect its
legal rights regarding the Rules.

The Arizona  legislature  has appointed a joint  legislative  committee to study
electric  utility industry  restructuring  issues and report back to them by the
end of 1997. The Company  believes that  legislation will ultimately be required
before  significant  implementation of retail electric  competition can lawfully
occur.

Until it has been further  determined  how  competition  will be  implemented in
Arizona,  the  Company  cannot  accurately  predict  the  impact of full  retail
competition on its financial position or results of operations.

Federal  The  Energy  Policy  Act of 1992 and  recent  rulemakings  by FERC have
promoted  increased  competition in the wholesale  electric  power markets.  The
Company  does not expect  these  rulemakings  to have a  material  impact on its
financial statements.

Several  electric  utility reform bills have been  introduced  during the recent
congressional  session,  which as currently  written,  would allow  consumers to
choose their electric  supplier by 2000 or 2003.  These bills,  other bills that
are expected to be  introduced,  and ongoing  discussions  at the federal  level
suggest  a wide  range of  

                                      -10-

opinion that will need to be narrowed  before any substantial  restructuring  of
the electric utility industry can occur.

Regulatory   Accounting  The  Company  prepares  its  financial   statements  in
accordance  with the provisions of Statement of Financial  Accounting  Standards
(SFAS) No. 71, "Accounting for the Effects of Certain Types of Regulation." SFAS
No. 71 requires a cost-based, rate-regulated enterprise to reflect the impact of
regulatory  decisions  in  its  financial  statements.  The  Company's  existing
regulatory  orders and current  regulatory  environment  support its  accounting
practices  related to regulatory  assets,  which amounted to approximately  $1.0
billion at June 30, 1997. In accordance with the 1996 regulatory  agreement (see
below),  the  ACC  accelerated  the  amortization  of  substantially  all of the
Company's regulatory assets over an eight-year period. If rate recovery of these
assets is no longer probable,  whether due to competition or regulatory  action,
the Company  would no longer be able to apply the  provisions  of SFAS No. 71 to
all or some part of its  operations,  which could have a material  impact on the
Company's financial statements.

1996 Regulatory Agreement

In April 1996, the ACC approved a regulatory  agreement  between the Company and
the ACC Staff. The major provisions of this agreement are:

o    An annual  retail  price  reduction  of  approximately  $48.5  million ($29
     million after income  taxes),  or 3.4% on average for all customers  except
     certain contract customers, effective July 1, 1996.

o    Recovery of substantially  all of the Company's  present  regulatory assets
     through  accelerated  amortization over an eight-year period beginning July
     1, 1996,  increasing annual amortization by approximately $120 million ($72
     million after income taxes).

o    A  formula  for  sharing   future  cost  savings   between   customers  and
     shareholders  (price reduction formula)  referencing a return on equity (as
     defined) of 11.25%.

o    A moratorium  on filing for  permanent  rate changes prior to July 2, 1999,
     except under the price  reduction  formula and under  certain other limited
     circumstances.

o    Infusion  of $200  million of common  equity  into the  Company by Pinnacle
     West, in annual payments of $50 million starting in 1996.

Pursuant to the price reduction formula,  in May 1997, the ACC approved a retail
price  reduction of  approximately  $17.6  million  annually  ($11 million after
income taxes), or 1.2%, effective July 1, 1997.

6. The Palo Verde  participants  have  insurance for public  liability  payments
resulting  from  nuclear  energy  hazards to the full limit of  liability  under
federal law. This 

                                      -11-

potential  liability  is covered  by primary  liability  insurance  provided  by
commercial  insurance  carriers in the amount of $200 million and the balance by
an  industry-wide  retrospective  assessment  program.  If losses at any nuclear
power plant covered by the programs  exceed the accumulated  funds,  the Company
could be assessed retrospective premium adjustments.  The maximum assessment per
reactor  under the  program  for each  nuclear  incident  is  approximately  $79
million,  subject to an annual limit of $10 million per incident. Based upon the
Company's  29.1% interest in the three Palo Verde units,  the Company's  maximum
potential  assessment per incident is approximately $69 million,  with an annual
payment limitation of approximately $9 million.

         The Palo Verde  participants  maintain  "all risk"  (including  nuclear
hazards) insurance for property damage to, and  decontamination  of, property at
Palo Verde in the aggregate  amount of $2.75 billion,  a substantial  portion of
which must first be applied to stabilization  and  decontamination.  The Company
has also secured  insurance against portions of any increased cost of generation
or  purchased  power  and  business  interruption  resulting  from a sudden  and
unforeseen outage of any of the three units. The insurance coverage discussed in
this and the previous  paragraph  is subject to certain  policy  conditions  and
exclusions.

7. The Company has encountered  tube cracking in the Palo Verde steam generators
and has taken, and will continue to take, remedial actions that it believes have
slowed the rate of tube  degradation.  The  projected  service life of the steam
generators is reassessed  periodically and these analyses  indicate that it will
be economically desirable for the Company to replace the Unit 2 steam generators
between 2003 and 2008. The Company  estimates that its share of the  replacement
costs (in 1997 dollars and including  installation and replacement  power costs)
will be approximately $50 million, most of which will be incurred after the year
2000. Based on the latest available data, the Company  estimates that the Unit 1
and Unit 3 steam  generators  should operate for the license periods (until 2025
and 2027, respectively),  although the Company will continue its normal periodic
assessment of these steam generators.

8. The Financial  Accounting  Standards  Board  recently  issued SFAS No. 130 on
"Reporting Comprehensive Income" and SFAS No. 131 on "Disclosures about Segments
of an Enterprise and Related Information." The "Reporting  Comprehensive Income"
standard is effective for fiscal years  beginning  after  December 15, 1997. The
standard changes the reporting of certain items currently reported in the common
stock equity section of the balance sheet and is not expected to have a material
effect on the Company's financial statements. The "Disclosures about Segments of
an Enterprise  and Related  Information"  standard is effective for fiscal years
beginning after December 15, 1997. This standard  requires that public companies
report  certain   information  about  operating   segments  in  their  financial
statements. It also establishes related disclosures about products and services,
geographic areas, and major customers.  The Company is currently evaluating what
impact this standard will have on its disclosures.

         The following table summarizes the Company's  revenues and earnings for
the  three-month,  six-month  and  twelve-month  periods ended June 30, 1997 and
1996:

         Operating  Results -  Three-month  period ended June 30, 1997  compared
         -----------------------------------------------------------------------
         with three-month period ended June 30, 1996
         -------------------------------------------

         Earnings were flat in the  three-month  comparison  as strong  customer
growth,  cost savings,  and increased sales due to weather offset the effects of
the 1996  regulatory  agreement  (see  Note 5 of Notes  to  Condensed  Financial
Statements).

         In the three-month comparison,  the regulatory agreement,  which became
effective  July 1,  1996,  resulted  in $29  million  (before  income  taxes) of
accelerated  regulatory  asset  amortization  and a retail price reduction which
reduced pretax revenues by $13 million.

         Results were favorably impacted by increased operating revenues (net of
related  fuel  expenses),  lower  operations  and  maintenance  expenses,  and a
decrease in other taxes.  Operating revenues increased $32 million primarily due
to a $24 million increase in sales for resale,  $15 million from retail customer
growth, and $6 million attributable to weather effects,  partially offset by the
1996 retail price reduction impact of $13 million. Sales for resale are sales of
electricity at wholesale to other electric utilities, power marketers, or public
authorities for resale to their customers.  The increase in sales for resale was
a result of  increased  activity  in  competitive  bulk  power  markets  and was
accompanied by significant increases in related purchased power.

                                      -13-

These bulk power activities did not result in a significant variance in earnings
due to market pressures on prices. Operation and maintenance expenses were lower
by $11 million  primarily  due to the timing of nuclear  refueling,  charges for
employee  incentive  plans in 1996, and savings from a 1996 voluntary  severance
program.  Other taxes  decreased  $5 million  primarily  due to a 1996 change in
property  tax law.  The impact of this tax law change for the first half of 1996
was recorded in the third quarter of 1996.

         Operating  Results - Six-month period ended June 30, 1997 compared with
         -----------------------------------------------------------------------
         six-month period ended June 30, 1996
         ------------------------------------

         Earnings  decreased in the six-month  comparison  due to the effects of
the 1996  regulatory  agreement  (see  Note 5 of Notes  to  Condensed  Financial
Statements).  These  effects  were  partially  offset by customer  growth,  cost
savings, and increased sales due to weather.

         In the six-month  comparison,  the regulatory  agreement,  which became
effective  July 1,  1996,  resulted  in $59  million  (before  income  taxes) of
accelerated  regulatory  asset  amortization  and a retail price reduction which
reduced pretax revenues by $24 million.

         Partially  offsetting these negative  factors were increased  operating
revenues  (net of related  fuel  expenses),  lower  operations  and  maintenance
expenses,  a decrease in other  taxes,  and lower  interest  expense.  Operating
revenues  increased $66 million primarily due to a $46 million increase in sales
for  resale,  $32 million of retail  customer  growth and higher  usage,  and $9
million  attributable to weather  effects,  partially  offset by the $24 million
impact of the retail price reduction.  Sales for resale are sales of electricity
at wholesale to other electric utilities, power marketers, or public authorities
for resale to their customers.  The increase in sales for resale was a result of
increased  activity in  competitive  bulk power markets and was  accompanied  by
significant  increases in related  purchased power.  These bulk power activities
did not result in a significant  variance in earnings due to market pressures on
prices. Operations and maintenance expenses were $11 million lower primarily due
to improved nuclear  operations,  charges for employee  incentive plans in 1996,
and savings from a 1996 voluntary  severance program.  Other taxes decreased $10
million  primarily  due to a 1996 change in property tax law. The impact of this
tax law change for the first half of 1996 was  recorded in the third  quarter of
1996.  Interest expense decreased $6 million due to lower average interest rates
and lower amounts of debt outstanding.

         Operating  Results -  Twelve-month  period ended June 30, 1997 compared
         -----------------------------------------------------------------------
         with twelve-month period ended June 30, 1996
         --------------------------------------------

         Earnings  decreased in the twelve-month  comparison ended June 30, 1997
due to the  effects  of the 1996  regulatory  agreement  (see Note 5 of Notes to
Condensed  Financial  Statements),  a $32  million  pretax  charge in the fourth
quarter of 1996 for a

                                      -14-

voluntary  severance  program,  and an increase in fuel expenses.  These effects
were partially offset by strong customer growth,  cost savings,  increased sales
due to  weather,  and the  recognition  of $8  million  of income  tax  benefits
associated with capital loss carryforwards. The twelve-month comparison was also
positively  impacted by $21 million of pretax  asset  write-downs  in the twelve
months ended June 30, 1996.

         In the twelve-month comparison,  the regulatory agreement, which became
effective July 1, 1996, resulted in $119 million of accelerated regulatory asset
amortization and a retail price reduction which reduced revenues by $54 million.
Fuel  expenses  increased  $86 million  primarily  due to  increased  retail and
wholesale  sales volumes and a less  favorable  mix of generation  and purchased
power, particularly during a regional power outage in August 1996.

         Operating  revenues increased $114 million primarily due to $72 million
of customer growth and higher usage, a $61 million increase in sales for resale,
and $26 million  attributable to weather  effects,  partially  offset by the $54
million  impact of the  retail  price  reduction.  Sales for resale are sales of
electricity at wholesale to other electric utilities, power marketers, or public
authorities for resale to their customers.  The increase in sales for resale was
accompanied by significant increases in related purchased power and was a result
of  increased  activity  in  competitive  bulk power  markets.  These bulk power
activities  did not result in a  significant  variance in earnings due to market
pressures on prices.  Other taxes decreased $29 million  primarily due to a 1996
change in property tax law. The impact of this tax law change for the first half
of 1996 was recorded in the third quarter of 1996.  Interest  expense  decreased
$12  million  due to lower  average  interest  rates and lower  amounts  of debt
outstanding.

         Other Income
         ------------

         As part of a 1994 rate  settlement  agreement with the ACC, the Company
accelerated  amortization  of  substantially  all deferred ITCs over a five-year
period  beginning in 1995,  resulting in a decrease in annual income tax expense
of approximately $21 million.

Liquidity and Capital Resources
- -------------------------------

         For  the  six  months  ended  June  30,  1997,  the  Company   incurred
approximately $146 million in capital  expenditures,  which is approximately 49%
of the most recently estimated 1997 capital expenditures.  The Company estimates
total  capital   expenditures   for  the  years  1997,  1998,  and  1999  to  be
approximately $296 million, $290 million, and $265 million, respectively.  These
amounts include about $30 million each year for nuclear fuel expenditures.

         Required and optional  redemptions of preferred  stock and repayment of
long-term debt, including premiums thereon, and payments for a capitalized lease
obligation are expected to total approximately $268 million,  $114 million,  and
$114 million for the 

                                      -15-

years 1997, 1998, and 1999,  respectively.  During the six months ended June 30,
1997, the Company redeemed  approximately $219 million of its long-term debt and
approximately  $46 million of its preferred  stock with funds from internal cash
from  operations  and long- and  short-term  debt.  The Company's cash flow from
operations is cyclical,  with the highest cash flows generated in the summer. As
a  result,  the  Company  expects  to pay  down  a  significant  portion  of its
short-term  debt  balance in the third  quarter of the year using cash flow from
operations. As a result of the 1996 regulatory agreement (see Note 5 of Notes to
Condensed  Financial  Statements),  Pinnacle  West  invested  $50 million in the
Company in 1996 and will invest similar amounts annually in 1997 through 1999.

         During the six months  ended June 30,  1997,  the Company  incurred $50
million of  long-term  debt under a revolving  credit  agreement  and issued $50
million of its senior  notes.  Simultaneously  with the  issuance  of the senior
notes,  the Company issued $50 million of its first mortgage bonds ("senior note
mortgage  bonds") to the senior note trustee as collateral for the senior notes.
The senior note mortgage  bonds have the same interest  rate,  interest  payment
dates,  maturity,  and redemption  provisions as the senior notes. The Company's
payments of principal,  premium, and/or interest on the senior notes satisfy the
Company's corresponding payment obligation on the senior note mortgage bonds. As
long as the senior note mortgage bonds secure the senior notes, the senior notes
will effectively rank pari passu with the first mortgage bonds. On the date that
the Company has repaid all of its first  mortgage  bonds,  other than those that
secure  senior notes,  the senior note mortgage  bonds will no longer secure the
senior notes and will cease to be outstanding.

         Although  provisions  in the  Company's  bond  indenture,  articles  of
incorporation,  and financing  orders from the ACC establish  maximum amounts of
additional first mortgage bonds and preferred stock,  management does not expect
any of these  restrictions  to limit the  Company's  ability to meet its capital
requirements.

Current Issues
- --------------

         The  Company's  ability to maintain  and  improve its current  level of
earnings will depend on several factors.  As the electric  industry becomes more
competitive, the Company's ability to reduce costs and increase productivity and
resource  utilization will be important factors in maintaining a price structure
that is both  attractive  to customers  and  profitable  to the  Company.  Other
important factors that could affect the Company's future earnings levels and any
forward-looking  statements  contained  in  this  "Management's  Discussion  and
Analysis of Financial  Condition and Results of Operations"  include  regulatory
developments;  competitive developments;  regional economic conditions; the cost
of debt and  equity  capital;  regulatory,  tax and  environmental  legislation;
weather variations  affecting customer usage; and technological  developments in
the electricity industry.

Environmental Matters
- ---------------------

        EPA Environmental Regulation
        ----------------------------

        Air Quality  Standards.  In July 1997 the EPA  proposed  regulations  on
regional haze. See "Environmental  Matters - EPA Environmental  Regulation - Air
Quality  Standards"  in Part I,  Item 1 of the 1996  10-K.  The  proposal  would
require states to submit plans to meet "presumptive reasonable progress targets"
for achieving perceptible improvements in visibility conditions in Federal Class
I areas (e.g.,  national  parks) every 10-15 years.  The proposal also calls for
states to conduct  three  year "best  available  retrofit  technology"  ("BART")
review on point sources which became operational between 1962 and 1977 and which
may  normally  be  anticipated   to  contribute  to  regional  haze   visibility
impairment. Because the actual level of emissions controls, if any, for any unit
cannot be determined at this time,  the Company  currently  cannot  estimate the
capital expenditures, if any, which would result from the final rules.

        Also in July 1997 EPA  promulgated  final  National  Ambient Air Quality
Standards for ozone and particulate  matter.  See  "Environmental  Matters - EPA

Regulation - Air Quality Standards" in Part I, Item 1 of the 1996 10-K. Pursuant
to the rules,  the ozone standard is more  stringent and a new ambient  standard
for very fine  particles  has been  established.  The Company does not currently
expect these rules to have a material  adverse effect on its financial  position
or results of operations.

         See Note 5 of Notes to Condensed Financial Statements in Part I, Item 1
of this report for a  discussion  of  competition  and the Rules  regarding  the
introduction of retail electric  competition in Arizona. On February 28, 1997, a
lawsuit was filed by the Company to protect its legal rights regarding the Rules
and in its complaint the Company asked the Court for (i) a judgment vacating the
retail electric  competition  rules, (ii) a declaratory  judgment that the rules
are unlawful because,  among other things, they were entered into without proper
legal  authorization,  and (iii) a  permanent  injunction  barring  the ACC from
enforcing or implementing the rules and from  promulgating any other regulations
without lawful authority.
