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 1994 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. Registrant's financial statements
        were prepared to permit the information required in the Financial Data
        Schedule (FDS), Exhibit 27, to be directly extracted from the filed
        statements. The FDS amounts correspond to or are calculable from the
        amounts reported in the financial statements or notes thereto.
 
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, 1995 and 1994 are not necessarily indicative of
        trends for any twelve-month period.
 
NOTE 4--On July 21, 1995, the Missouri Public Service Commission approved an
        agreement involving the registrant's Missouri electric rates. The
        agreement provides for a rate decrease for all classes of Missouri
        retail electric customers, effective August 1, 1995, reducing annual
        revenues by $30 million. In addition, a one-time $30 million credit to
        current Missouri electric customers will reduce third quarter 1995
        earnings approximately 18 cents per share. Also included is a three-
        year plan which provides that earnings in excess of a 12.61 percent
        return on equity will be shared equally between customers and
        stockholders and earnings above a 14 percent return on equity will be
        credited to customers. Also, the agreement provides that no party shall
        file for a general increase or decrease in registrant's Missouri retail
        electric rates prior to July 1, 1998, except that the registrant may
        file for an increase if certain adverse events occur.
 
NOTE 5--On August 11, 1995, the registrant entered into an Agreement and Plan
        of Merger with CIPSCO Incorporated, an Illinois corporation, Arch
        Holding Corp., a Missouri corporation, and Arch Merger Inc., a Missouri
        corporation. Information regarding this event is provided under "Item
        5. Other Events" of this Quarterly Report on Form 10-Q.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                          OF THE RESULTS OF OPERATIONS
 
  Second quarter 1995 common stock earnings were $72.7 million or 71 cents per
share, a decrease of $21.4 million from 1994's second quarter. Earnings per
share in the second quarter of 1995 were 21 cents lower than in the comparable
1994 period.
 
  Common stock earnings for the six months ended June 30, 1995 were $107.6
million, a decrease of $21.4 million from the same period in 1994. Earnings of
$1.05 per share during the six months ended June 30, 1995 were 21 cents lower
than in the comparable 1994 period.
 
  Common stock earnings for the twelve months ended June 30, 1995 were $286.2
million, a $2 million decrease from the preceding twelve-month period. Earnings
of $2.80 per share for the twelve months ended June 30, 1995 decreased 2 cents
per share from the twelve months ended June 30, 1994.
 
  The decreased earnings for the three months and six months ended June 30,
1995 versus the comparable 1994 periods resulted from decreased operating
revenues, greater operating expenses and increased interest charges. The lower
revenues were primarily from lower electricity sales this year due to mild
weather and the increased expenses related to the 1995 Callaway nuclear plant
refueling.
 
  The decreased earnings for the twelve months ended June 30, 1995 versus the
prior twelve-month period also reflects lower electric operating revenues and
higher interest charges offset almost entirely by reduced operating expenses.
Operating expenses were down primarily due to lower fuel and purchased power
costs and reduced purchased gas costs.
 
  The impact of significant items affecting revenues, costs and earnings during
the three-month, six-month and twelve-month periods ended June 30, 1995 and
1994 is detailed below:

unchanged from the year-ago quarter and industrial sales gained 3 percent while
weather-sensitive residential sales declined 8 percent.
 
  Kilowatt-hour sales for the six months ended June 30, 1995 were unchanged
from the comparable 1994 period. Residential sales decreased 4 percent,
commercial sales increased 1 percent and industrial sales grew 4 percent.
 
  Kilowatt-hour sales for the twelve months ended June 30, 1995 were even with
the prior twelve-month period. Commercial and industrial sales were up 1

                              ======             =====              ======

 
  The increase in fuel and purchased power costs during the three months ended
June 30, 1995, versus the three months ended June 30, 1994, is primarily due to
higher fuel prices and increased generation, partially offset by lower net
purchased power costs. The higher fuel prices are due to the absence of nuclear
generation during the Callaway plant's 48 day refueling outage.
 
  The increase in fuel and purchased power costs during the six months ended
June 30, 1995, versus the six months ended June 30, 1994, is primarily due to
increased net purchased power costs and higher fuel prices, resulting from the
Callaway plant refueling outage, partially offset by reduced generation.
 
  The decreased fuel costs for the twelve months ended June 30, 1995, versus
the twelve months ended June 30, 1994, reflects reduced net purchased power
costs and lower fuel prices, partially offset by increased generation. The 1993
flood-interrupted coal deliveries reduced generation and increased net
purchased power costs in the prior twelve-month period.
 
  Other operating expense variations reflect recurring conditions such as
growth, inflation and wage increases. During the three months ended June 30,
1995, versus the comparable 1994 period, operations expenses other than fuel
and purchased power declined $2 million primarily due to a $3 million decrease
in purchased gas costs and other expenses offset by a $1 million increase in
labor expenses. Maintenance expenses during the current three-month period were
$13 million higher primarily due to Callaway plant maintenance during the 1995
refueling outage.
 
  During the six months ended June 30, 1995, versus the comparable 1994 period,
operations expenses other than fuel and purchased power, were $14 million
lower, primarily due to an $11 million decrease in purchased gas costs, and
lower employee welfare expenses, injuries and damages, insurance premiums,
regulatory fees, and research and development costs. Maintenance expenses for
the current six-month period were $21 million higher primarily due to increases
of $19 million for power plant maintenance and $2 million for
transmission/distribution system maintenance. The Callaway refueling outage
accounted for $14 million of the power plant expense increase, with $5 million
attributable to fossil-fueled plant maintenance.
 
  For the twelve months ended June 30, 1995, versus the prior twelve-month
period, operations expenses other than fuel and purchased power, were $24
million lower, primarily due to a $16 million reduction in purchased gas costs,
a $6 million decrease in labor costs and a $2 million drop in other expenses.
Maintenance expenses for the current twelve-month period increased $19 million
primarily due to increases of $16 million for maintenance expenses at our
fossil-fueled power plants and $3 million for transmission/distribution system
maintenance.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                    OF THE RESULTS OF OPERATIONS (CONTINUED)
 
  Depreciation expense for the three-month, six-month and twelve-month periods
ended June 30, 1995, versus the comparable 1994 periods, increased $2 million,
$4 million and $8 million, respectively, primarily due to increases in
depreciable property.
 
  Other taxes charged to operating expenses increased $1 million during the six
months ended June 30, 1995, versus the comparable 1994 period resulting from
real estate tax increases, partially offset by reduced gross receipts taxes.
 
  Income taxes charged to operating expenses decreased $13 million and $14
million, respectively, during the three and six months ended June 30, 1995,
versus the comparable 1994 periods, primarily due to lower pretax income.
 
OTHER INCOME AND DEDUCTIONS
 
  Miscellaneous other net income and deductions decreased $6 million for the
twelve months ended June 30, 1995, versus the comparable 1994 period, primarily
reflecting increased charitable contributions.
 
INTEREST
 
  During the three, six and twelve months ended June 30, 1995 versus the
comparable prior year periods, interest increased $1 million, $2 million and
$14 million, respectively, primarily due to higher interest rates on variable
rate long-term debt and increased total debt outstanding.
 
ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION (AFC)
 
  Variations in AFC track construction work in progress and changes were not
significant for the reporting periods. During the twelve-month periods ended
June 30, 1995 and 1994, AFC rates averaged 9.2 percent and 8.5 percent,
respectively.

                             OF FINANCIAL CONDITION
 
LIQUIDITY AND CAPITAL RESOURCES
 
  In June 1995, the registrant redeemed $3,000,000 of matured 4-3/4% Series
First Mortgage Bonds.

                           PART II. OTHER INFORMATION
 
ITEM 5. OTHER MATTERS
 
  On July 21, 1995, the Missouri Public Service Commission approved a
settlement agreement among all parties involving the registrant's Missouri
retail electric rates. The agreement provides for a rate decrease for all
classes of Missouri retail electric customers, effective August 1, 1995,
reducing annual revenues by $30 million. In addition, a one-time credit of $30
million will be granted. Also included is a three-year plan which provides that
earnings in excess of 12.61% return on equity will be shared equally by the
registrant's customers and shareholders. Earnings in excess of a 14.00% return
on equity will be credited entirely to customers. The agreement also provides
that no party shall file for a general increase or decrease in registrant's
Missouri retail electric rates for a period of three years, except that the
registrant may file for an increase if certain adverse events occur.
 
  On August 11, 1995, the registrant entered into an Agreement and Plan of
Merger (the "Merger Agreement") with CIPSCO Incorporated, an Illinois
corporation ("CIPSCO"), Arch Holding Corp., a newly formed Missouri corporation
50% owned by the registrant and 50% owned by CIPSCO ("Arch Holding"), and Arch
Merger Inc., a newly formed Missouri corporation and wholly owned subsidiary of
Arch Holding ("Merger Sub"), pursuant to which, among other things, Merger Sub
will be merged with and into the registrant and CIPSCO will be merged with and
into Arch Holding (the "Mergers"), with the result that the registrant and
Central Illinois Public Service Company, an Illinois corporation and the wholly
owned operating subsidiary of CIPSCO, as well as other direct subsidiaries of
CIPSCO, will continue as wholly owned operating subsidiaries of Arch Holding.
As a result of the Mergers, each outstanding share of the registrant's common
stock, par value $5.00 per share ("Common Stock"), (other than shares with
respect to which dissenters' rights are perfected under applicable state laws)
will be converted into the right to receive one share of common stock of Arch
Holding, par value $0.01 per share ("Arch Holding Common Stock"), each
outstanding share of the registrant's preferred stock, without par value,
(other than shares with respect to which dissenters' rights are perfected under
applicable state laws), will remain outstanding and unchanged and each
outstanding share of CIPSCO's common stock, without par value ("CIPSCO Common
Stock") (including shares with respect to which dissenters' rights are
perfected under applicable state laws) will be converted into the right to
receive 1.03 shares of Arch Holding Common Stock (or cash in lieu of fractional
shares otherwise deliverable in respect thereof).
 
  After the Mergers, Arch Holding will become a registered public utility
holding company under the Public Utility Holding Company Act of 1935, as
amended. The Mergers are conditioned upon, among other things, approval by
holders of two-thirds of the Common Stock and of the preferred stock, without
par value, of the registrant voting together as a single class, by holders of
two-thirds of the CIPSCO Common Stock, and upon receipt of certain regulatory
and governmental approvals. The foregoing description of the Merger Agreement
is qualified in its entirety by reference to the Merger Agreement, which is
attached as Exhibit 2(a) hereto and incorporated herein by reference in its
entirety.
 
  Simultaneous with their execution and delivery of the Merger Agreement, the
registrant and CIPSCO entered into stock option agreements (the "Stock Option
Agreements"), pursuant to one of which the registrant granted CIPSCO the right,
upon the terms and subject to the conditions set forth therein, to purchase up
to 6,983,233 shares of Common Stock at a price of $35.94 per share, and
pursuant to the other of which CIPSCO granted the registrant the right, upon
the terms and subject to the conditions set forth therein, to purchase up to
6,779,838 shares of CIPSCO Common Stock of a price of $37.02 per share. The
foregoing description of the Stock Option Agreements is qualified in its
entirety by reference to the Stock Option Agreements, which are attached as
Exhibits 10(a) and 10(b) hereto, respectively, and incorporated herein by
reference in their entirety.
 
  A copy of the Press Release, dated August 14, 1995, issued by the registrant
and CIPSCO relating to the Mergers is attached as Exhibit 99(a) hereto and is
incorporated herein by reference in its entirety.
