 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

 Note 1 -  Financial statement note disclosures, normally included in financial
           statements prepared in conformity with generally accepted accounting
           principles, have been omitted in this Form 10-Q pursuant to the Rules
           and Regulations of the Securities and Exchange Commission.  However,
           in the opinion of the registrant, the disclosures contained in this
           Form 10-Q are adequate to make the information presented not
           misleading.  See Notes to Financial Statements included in the 1993
           Annual Report on Form 10-K for information relevant to the financial
           statements contained in this Form 10-Q, including information as to
           the significant accounting policies of the registrant.

 Note 2 -  In the opinion of the registrant the interim financial statements
           filed as part of this Form 10-Q reflect all adjustments, consisting
           only of normal recurring adjustments, necessary to a fair statement
           of the results for the periods presented.

 Note 3 -  Due to the effect of weather on sales and other factors which are
           characteristic of public utility operations, financial results for
           the periods ended June 30, 1994 and 1993 are not necessarily
           indicative of trends for any twelve-month period.

 Note 4 -  Electric rates charged to customers provide for recovery of Callaway
           Plant decommissioning costs over the life of the plant, based on an
           assumed 40-year life, ending with expiration of the plant's operating
           license in 2024.  The Callaway site is assumed to be decommissioned
           using the DECON (immediate dismantlement) alternative.
           Decommissioning costs, including decontamination, dismantling and
           site restoration, are estimated to be $372 million in current year
           dollars and are expected to escalate 4.5% per year through the end of
           decommissioning activity in 2033.  Decommissioning costs are charged
           to depreciation expense over Callaway's service life and amounted to
           $6.7 million in 1993 and $3.3 million in the first six months of
           1994.  Every three years, the Missouri Public Service Commission
           (MoPSC) requires the registrant to file updated cost studies for
           decommissioning Callaway and rates may be adjusted at such times to
           reflect changes in assumptions.  The MoPSC has approved the costs
           currently being collected from customers and deposited in an external
           trust fund established to provide for Callaway's decommissioning.
           Fund earnings are expected to average 10.4% thru 2017 and 8.4%
           thereafter until 2033.  If the assumed return on trust assets is not
           earned, the registrant believes it is probable that such earnings
           deficiency will be recovered in rates.  Trust fund earnings, net of
           expenses appear on the balance sheet as increases in Nuclear
           decommissioning trust fund and in the Accumulated provision for
           nuclear decommissioning.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                          OF THE RESULTS OF OPERATIONS


   Second quarter 1994 common stock earnings were $94.1 million, an increase of
$10.7 million from the second quarter of 1993.  Earnings of 92 cents per share
in the second quarter of 1994 were 10 cents higher than in the comparable 1993
period.

   Common stock earnings for the six months ended June 30, 1994 were $129.0
million, an increase of $5.1 million from the same period in 1993.  Earnings of
$1.26 per share during the six months ended June 30, 1994 were 5 cents higher
than in the comparable 1993 period.

   Common stock earnings for the twelve months ended June 30, 1994 totaled
$288.1 million, a $32.4 million decrease from the preceding twelve-month period.
Earnings of $2.82 per share during the twelve months ended June 30, 1994
decreased 32 cents from the twelve months ended June 30, 1993.

   The increased earnings for the three and six months ended June 30, 1994 over
the comparable 1993 periods, reflect higher electric revenues and lower electric
fuel and purchased power costs.  Partially offsetting these benefits were
increased other operating expenses and higher taxes.
 
   The lower earnings for the twelve months ended June 30, 1994 versus the prior
twelve-month period reflects registrant's $18 million net gain on the sale of
its Iowa and northern Illinois electric properties in December, 1992, higher
income taxes from increased federal and Missouri rates and greater operating
expenses, partially offset by increased electric revenues, lower fuel prices and
reduced interest expenses.  The higher operating expenses are the result of a
Callaway plant nuclear refueling in the Fall of 1993, expenses associated with
the 1993 summer floods and accruing postretirement benefits costs beginning in
January, 1993.

   The impact of the more significant items affecting revenues, costs and
earnings during the three-month, six-month and twelve-month periods ended June
30, 1994 and 1993 is detailed below:

   Second quarter 1994 kilowatt-hour sales increased 6 percent from the same
quarter of 1993, primarily due to hot June weather this year.  Residential and
commercial sales each increased almost 8 percent while less weather-sensitive
industrial sales increased about 1 percent.

   Kilowatt-hour sales for the six months ended June 30, 1994 were 3 percent
higher than the comparable 1993 period, primarily due to the warmer than normal
weather in the second quarter; temperatures were greater than 90 degrees for 16
days in June 1994.  Residential and commercial sales increased 3 percent and 5
percent, respectively, with industrial sales increasing 1 percent.

   Kilowatt-hour sales during the twelve months ended June 30, 1994 were up 3
percent from the twelve-month period ending June 30, 1993.  Residential and
commercial sales increased 7 percent and 4 percent, respectively, while sales to
industrial customers decreased by 6 percent.

   The decreased fuel and purchased power costs during the three-month and six-
month periods ended June 30, 1994 versus the comparable periods in 1993, reflect
lower fuel prices, reduced fossil fuel generation and increased generating
efficiencies partially offset by higher net purchased power costs.

   The decreased fuel costs for the twelve months ended June 30, 1994, versus
the twelve months ended June 30, 1993, reflect reduced fossil-fueled generation
caused by 1993 flood-interrupted coal deliveries and Callaway plant's nuclear
refueling outage in the Fall of 1993, lower fuel prices and increased generating
efficiencies partially offset by increased net purchased power costs.

   Other operating expense variations reflect recurring conditions such as
growth, inflation and wage increases.  During the three months ended June 30,
1994, versus the comparable 1993 period, operations expenses, other than fuel
and purchased power, decreased $1 million, primarily due to lower employee
welfare costs.  Maintenance expenses during the same period increased $4
million, primarily reflecting increased expenses at our fossil-fueled power
plants.

   During the six months ended June 30, 1994, versus the comparable 1993 period,
operations expenses, other than fuel and purchased power, were essentially
unchanged.  Maintenance expenses during the same period were $9 million higher
primarily due to increased power plant maintenance.

   For the twelve months ended June 30, 1994, versus the prior twelve-month
period, operations expenses, other than fuel and purchased power, increased $28
million, primarily due to a $13 million increase in accruing employee
postretirement benefit expenses, a $7 million increase in labor costs, and
higher pension, professional service, regulatory fees, computer services and
tree trimming costs.  Maintenance expenses during the same period increased $30
million primarily due to the Callaway plant nuclear refueling outage in the Fall
of 1993, flood-related expenses and increased power plant maintenance.

   Depreciation expense for the three-month, six-month and twelve-month periods
ended June 30, 1994, versus the comparable 1993 periods increased $2 million, $3
million and $4 million, respectively, primarily due to increases in depreciable
property.

   Elimination of the amortization of phase-in credits associated with the
registrant's nuclear plant phase-in plan reduced operating expenses by $17
million for the twelve months ended June 30, 1994.

   Other taxes charged to operating expenses during the three-month, six-month
and twelve-month periods ended June 30, 1994, versus the comparable prior
periods, increased $3 million, $4 million, and $6 million, respectively,
primarily due to increased real estate and gross receipts taxes.

                    OF THE RESULTS OF OPERATIONS (Continued)


Operating Expenses (Continued)
- ------------------            


   Income taxes charged to operating expenses during the three and six months
ended June 30, 1994, versus the comparable prior periods, increased $12 million
and $14 million, respectively, primarily due to higher pre-tax income and
increased federal and Missouri income tax rates.  During the twelve months ended
June 30, 1994, versus the twelve months ended June 30, 1993, income taxes
increased $3 million primarily due to increased federal and Missouri income tax
rates.

Other Income and Deductions
- ---------------------------

   Miscellaneous other net income and deductions decreased $12 million for the
twelve months ended June 30, 1994, versus the twelve months ended June 30, 1993,
reflecting the gain on the sale of the registrant's Iowa and northern Illinois
electric distribution properties in December 1992, partially offset by lower
miscellaneous income deductions.

Interest
- --------

   During the three months ended June 30, 1994, versus the comparable 1993
period, interest increased $1 million primarily reflecting increased debt
outstanding and higher interest rates on variable rate debt.

   During the twelve months ended June 30, 1994 versus the comparable prior year
period, interest decreased $2 million, primarily reflecting the reduction of
total debt outstanding.

Allowance for Funds Used During Construction (AFC)
- --------------------------------------------------

   Variations in AFC track variations in construction work in progress and were
not significant for the reporting periods.  During the twelve-month periods
ended June 30, 1994 and 1993, AFC rates averaged 8.5 percent and 7.0 percent,
respectively.
