       A.     INTRODUCTION

       This Application-Declaration seeks approvals relating to the proposed
Merger of AEP and CSW. Pursuant to the Merger Agreement, AEP will acquire all of
the issued and outstanding shares of CSW Common Stock. Both AEP and CSW are
registered with the Commission as holding companies under the 1935 Act.
(References to "AEP" or "CSW" refer to each Applicant and/or its subsidiaries,
jointly or separately.)

       AEP owns all of the outstanding shares of common stock of seven U.S.
electric utility operating subsidiaries: APCo, CSPCo, I&M, KPCo, KgPCo, OPCo and
WPCo. The service area of AEP's electric utility subsidiaries covers portions of
Indiana, Kentucky, Michigan, Ohio, Tennessee, Virginia and West Virginia. AEP
also owns all of the common stock of AEGCo and AEPSC, among others. AEP
indirectly owns 50% of the outstanding share capital of Yorkshire Electricity.

       CSW owns all of the outstanding shares of common stock of four U.S.
electric utility operating subsidiaries: CPL, PSO, SWEPCO and WTU. The service
area of CSW's electric utility subsidiaries covers portions of Arkansas,
Louisiana, Oklahoma and Texas. CSW also owns all of the common stock of CSWS,
among others, and indirectly owns all of the outstanding share capital of
SEEBOARD.

       The Merger Agreement provides for a business combination of AEP and CSW
in which Merger Sub will be merged into CSW. CSW will be the surviving
corporation and will become a wholly owned subsidiary of AEP. Immediately
following the Merger, the Combined Company will be a holding company with
respect to CSW, which, in turn, will be a holding company with respect to the
electric utility subsidiaries and other subsidiaries it currently owns (with the
exception of CSWS, which will be merged into AEPSC, and CSW Credit, which will
be directly held by the Combined Company). AEP's utility and non-utility
subsidiaries will remain subsidiaries of AEP, and CSW's utility and non-utility
subsidiaries, which will continue to be owned by CSW, will become indirect
subsidiaries of AEP (except for CSWS and CSW Credit). The final ownership
structure has not yet been determined.

       Upon consummation of the Merger, each share of issued and outstanding CSW
Common Stock (other than Excluded Shares) will be exchangeable for 0.60 shares
of AEP Common Stock. The former holders of CSW Common Stock will own
approximately 40% of the outstanding shares of AEP Common Stock after the
Merger. The only voting securities of AEP that will be publicly held will be AEP
Common Stock; the Merger is expected to have no effect on the issued and
outstanding public debt securities, preferred stock and/or preferred trust
securities of CSW and the respective subsidiaries of AEP and CSW.

       With respect to the cost of capital of AEP and CSW, the nationally
recognized rating agencies of Moody's Investors Service, Standard & Poor's, Duff
& Phelps and Fitch reaffirmed their rating of the outstanding first mortgage
bonds, commercial paper and other rated securities of AEP and CSW and/or their
subsidiaries shortly after the Merger announcement. Since that time, there has
been no merger-related change in any of the ratings by the rating agencies.


                                                                              12
<PAGE>   13


       The Merger will produce substantial benefits to the public, investors and
consumers and will meet all applicable standards of the 1935 Act. Applicants
believe that the Merger offers significant strategic and financial benefits to
them and to their respective shareholders, as well as to their employees,
customers and the communities in which they provide service. These benefits
include, among others:

              (i) The Combined Company will operate more efficiently and be
       better equipped to keep rates low in an increasingly competitive electric
       utility industry;

              (ii) The Combined Company will achieve savings through the
       elimination of duplication in corporate and administrative programs,
       greater efficiencies in operations and business processes, improved
       purchasing power, and the combination of two workforces;

              (iii) The Merger will result in a Combined Company with a stronger
       financial base, improved position in the credit markets and greater
       market diversity;

              (iv) The Merger will diversify the service territory of the
       Combined System, reducing exposure to local changes in economic and
       competitive conditions; and

              (v) The Merger will enhance the profitability of the Combined
       Company through increased scale.

       Applicants estimate the net non-fuel savings from the Merger to be nearly
$2 billion and the net fuel-related savings to be approximately $98 million over
the first ten years following the Merger. The projected Merger fuel and non-fuel
savings are discussed in greater detail in Item 3.B.2 below. A copy of the
Merger Agreement is incorporated by reference and attached as Exhibit B-1.

       At their Annual Meeting on May 27, 1998, holders of AEP Common Stock
overwhelmingly approved the shareholder actions necessary to effect the Merger.
The following day, holders of CSW Common Stock overwhelmingly approved the
Merger at their Annual Meeting. Various aspects of the Merger are subject to the
approval of this Commission as well as the: (i) FERC; (ii) NRC; (iii) FCC; (iv)
Louisiana Commission; (v) Oklahoma Commission; and (vi) Arkansas Commission. In
addition, the Applicants must obtain pre-Merger clearance from the DOJ according
to procedures set forth in the HSR Act and a determination by the Texas
Commission that the Merger is consistent with the public interest. Applicants
have made filings with each of these regulatory agencies. The NRC approved the
transfer of control of CPL's NRC licenses, a copy of which is filed as Exhibit
D-6.2 and incorporated by reference. In July 1999, Applicants filed with the DOJ
under the HSR Act. On July 29, 1999, Applicants filed an application with the
FCC to transfer control of certain licenses held by CSW subsidiaries to AEP, a
copy of which is filed as Exhibit D-9.1. Orders approving the Merger have been
received from the Arkansas Commission, the Louisiana Commission, the Oklahoma
Commission, the Kentucky Commission, and the Indiana Commission, copies of which
are filed as Exhibit D-2.2, Exhibit D-3.2, Exhibit D-4.2, Exhibit D-7.1, and
Exhibit D-8.1, respectively, and incorporated by reference. At FERC, a
procedural schedule has been adopted which directs the Administrative Law Judge
to issue an Initial Decision no later than November 24, 1999. This schedule will


                                                                              13
<PAGE>   14


allow FERC to issue a decision no later than March 2000. To realize the benefits
of the Merger promptly, Applicants ask that the Commission review this
Application-Declaration and issue an order approving the Merger and granting
authority for the attendant transactions set forth above as expeditiously as
practicable without a hearing.

       B.     DESCRIPTION OF THE PARTIES TO THE MERGER

          1.     General Description

              a.     AEP

Riverside Plaza, Columbus, Ohio. AEP was incorporated under the laws of the
State of New York in 1906 and reorganized in 1925. AEP is a registered public
utility holding company that owns all of the outstanding shares of common stock
of seven U.S. electric utility operating subsidiaries: APCo, CSPCo, I&M, KPCo,
KgPCo, OPCo and WPCo. Most of the operating revenues of AEP and its subsidiaries
are derived from sales of electricity. AEP also owns, either directly or
indirectly, all of the common stock of four material non-utility businesses --
AEP Resources, AEPRESCO, AEPC, and AEPES -- and all of the common stock of two
other businesses -- AEGCo and AEPSC. AEP indirectly owns 50% of the outstanding
share capital of Yorkshire Electricity.

       AEP and its subsidiaries are subject to the broad regulatory provisions
of the 1935 Act administered by the Commission. Various of its subsidiaries are
also subject to regulation by the FERC under the FPA with respect to rates for
interstate sale at wholesale and transmission of electric power, accounting and
other matters and construction and operation of hydroelectric projects.

       AEP's electric utility operating subsidiaries serve approximately 3
million customers in Indiana, Kentucky, Michigan, Ohio, Tennessee, Virginia and
West Virginia. The generating and transmission facilities of these subsidiaries
are physically interconnected, and their operations are coordinated, as a single
integrated electric utility system. Transmission networks are interconnected
with extensive distribution facilities in the territories served.

       At December 31, 1997, the U.S. subsidiaries of AEP had a total of 17,844
employees. AEP, as such, has no employees. The electric utility operating
subsidiaries of AEP are each described below:

<PAGE>   16

       petroleum refining and chemicals. OPCo's retail rates and certain other

       AEGCo was organized in Ohio in 1982 as an electric generating company.
AEGCo sells power at wholesale to I&M, KPCo and Virginia Electric and Power
Company, an unaffiliated public utility. AEGCo has no employees.

       AEPSC provides, at cost, accounting, administrative, information systems,
engineering, financial, legal, maintenance and other services to the AEP
companies. The executive officers of AEP and its public utility subsidiaries are
all employees of AEPSC.

       AEP, primarily through AEP Resources, AEPRESCO, AEPC, and AEPES, pursues
new non-utility business opportunities, particularly those which allow use of
its expertise. These subsidiaries are described below:

              AEP Resources' primary business is development of, and investment
       in, EWGs, FUCOs, QFs and other energy-related domestic and international
       investment opportunities and projects.

              AEP Resources indirectly owns 50% of the outstanding share capital
       of Yorkshire Electricity. Yorkshire Electricity is principally engaged in
       the distribution of electricity to approximately 2.1 million customers in
       its authorized service territory which is comprised of 3,860 square miles
       and located centrally on the east coast of England.

              AEP Resources' indirect subsidiary, AEP Pushan Power, LDC, has a
       70% interest in Nanyang Electric, a joint venture organized to develop
       and build two 125 MW coal-fired generating units near Nanyang City in the
       Henan Province of The Peoples' Republic of China. Funding for the
       construction of the generating units has commenced and will continue
       through completion thereof, which is expected to occur sometime before
       the end of 1999.

              A subsidiary of AEP Resources also has an equity interest, which,
       subject to certain conditions, could reach 20%, in Pacific Hydro Limited,
       an Australian company that develops and operates hydroelectric
       facilities.

              In December 1998, AEP Resources, through wholly-owned
       subsidiaries, acquired CitiPower Pty., an electric distribution and
       retail sales company in Victoria, Australia. CitiPower Pty. serves
       approximately 240,000 customers in a service area that covers
       approximately 100 square miles in the city of Melbourne.


                                                                              16
<PAGE>   17


              In December 1998, AEP Resources acquired from Equitable Resources,
       Inc. midstream gas operations consisting of: (i) a 2,000-mile intrastate
       pipeline system in Louisiana, (ii) four natural gas processing plants
       that straddle the pipeline, and (iii) a storage facility, including an
       existing salt dome storage cavern and a second cavern under construction,
       both connected to the most active gas trading area in North America. The
       pipeline and storage facility are interconnected to 15 interstate and 23
       intrastate pipelines. The gas trading and marketing group included in
       this purchase was acquired by AEPES.

              AEP received approval from the Commission under the 1935 Act to
       issue and sell securities in an amount up to 100% of its consolidated
       retained earnings (approximately $1,645,000,000 at June 30, 1998) for
       investment in EWGs and FUCOs through AEP Resources. American Elec. Power
       Co., HCAR No. 26864 (Apr. 27, 1998).

              AEPRESCO offers engineering, construction, project management and
       other consulting services for projects involving transmission,
       distribution or generation of electric power both domestically and
       internationally.

              AEPC, an "exempt telecommunications company" under the 1935 Act,
       was formed in 1997 to pursue opportunities in the telecommunications
       field. AEPC operates a fiber optic line that runs through Kentucky, Ohio,
       Virginia and West Virginia. This fiber optic line is capable of providing
       high speed telecommunications capacity to other telecommunications
       companies. In addition to establishing and providing fiber optic
       services, AEPC also made investments in two companies engaged in
       providing digital personal communications services, the West Virginia PCS
       Alliance, LLC and the Virginia PCS Alliance, LLC.

              AEPES is authorized to engage in energy-related activities,
       including marketing electricity, gas and other energy commodities. As
       noted above, AEPES acquired the gas trading and marketing group of
       Equitable Resources, Inc. AEPES is an energy-related company under Rule
       58.

       AEP Common Stock is listed on the New York Stock Exchange, Inc. under the
trading symbol, "AEP." As of August 31, 1998, there were 190,915,648 shares of
AEP Common Stock outstanding. All shares of the common stock of APCo, CSPCo,
I&M, KPCo, KgPCo, OPCo and WPCo are held by AEP.

       APCo has four series of cumulative preferred stock issued and
outstanding, one of which is listed on a public securities exchange. As of June
30, 1998, there were 194,902 shares of its 4-1/2% Cumulative Preferred Stock
outstanding (listed on the Philadelphia Stock Exchange); 77,100 shares of its
5.90% Series Cumulative Preferred Stock outstanding; 61,500 shares of its 5.92%
Cumulative Preferred Stock outstanding; and 84,500 shares of its 6.85%
Cumulative Preferred Stock outstanding.

       CSPCo has one series of cumulative preferred stock outstanding that is

CSW companies, primarily for CSW's U.S. electric utility subsidiaries. After the
Merger, services performed by CSWS will be performed by AEPSC.

       CSW's material non-utility businesses are conducted through CSW Energy,
CSW International, CSW Energy Services, C3 Communications, CSW Credit, EnerShop
and CSW Leasing. These subsidiaries are described below:

              CSW Energy develops, owns and operates independent power
       production and cogeneration facilities within the U.S. Currently, CSW
       Energy has ownership interests in seven projects, six in operation and
       one in development.

              CSW International engages in international activities, including
       developing, acquiring, financing and owning EWGs and FUCOs, either alone
       or with local or other partners. CSW International indirectly owns all of
       the outstanding share capital of SEEBOARD. CSW acquired indirect control
       of SEEBOARD in April 1996. SEEBOARD's principal regulated businesses are
       the distribution and supply of electricity. SEEBOARD is engaged in other
       businesses, including gas supply, electricity generation and electrical
       contracting. SEEBOARD's service area covers approximately 3,000 square
       miles in southeast England. The service area extends from the outlying
       areas of London to the English Channel.

              CSW received approval from the Commission under the 1935 Act to
       issue and sell securities in an amount up to 100% of its consolidated
       retained earnings (approximately $1,781,000,000 at June 30, 1998) for
       investment in EWGs and FUCOs through CSW Energy and CSW International.
       Central and South West Corp., et al., HCAR No. 26653 (January 24, 1997).

              CSW Energy Services was formed to compete in restructured electric
       utility markets and serves as an energy service provider to wholesale and
       retail customers. It also engages in the business of marketing, selling,
       and leasing to certain consumers throughout the United States certain
       electric vehicles and retrofit kits subject to limitations imposed by the
       Commission.

              C3 Communications has two main lines of business. C3
       Communications' Utility Automation Division specializes in providing
       automated meter reading and related services to investor-owned municipal
       and cooperative electric utilities. C3 Communications also offers systems
       to aggregate meter data from a variety of technologies and vendor
       products that span multiple communication mode infrastructures including
       broadband, wireless network, power line carrier and telephony-based
       systems. C3 Communications is an "exempt telecommunications company"
       under the 1935 Act.

              CSW Credit was originally formed to purchase, without recourse,
       accounts receivable from the CSW electric utility subsidiaries to reduce
       working capital requirements. Because CSW Credit's capital structure is
       more highly leveraged than that of the CSW electric utility subsidiaries
       and due to CSW Credit's higher short-term debt ratings, CSW's overall
       cost of capital is lower. Subsequent to its formation, under the 1935
       Act, CSW Credit's business has expanded to include the purchase, without
       recourse,


                                                                              20

       of accounts receivable from certain non-affiliated parties subject to
       limitations imposed by the Commission.

              EnerShop, an energy-related company under Rule 58, provides energy
       services to commercial, industrial, institutional and governmental
       customers in Texas. These services help reduce a customer's operating
       costs through increased energy efficiencies and improved equipment
       operations. EnerShop utilizes the skills of local trade allies in
       offering services that include facility analysis; project management;
       engineering design; equipment procurement; and construction and
       performance monitoring.

              CSW Leasing, approved by the Commission in 1985, is a joint
       venture with CIT Group/Capital Equipment Financing. It was formed to
       invest in leveraged leases.

       APCo, CSPCo, I&M, KPCo and OPCo are parties to an Interconnection
Agreement, dated July 6, 1951, as amended, defining how they share the costs and
benefits associated with the AEP System's generating plants. Sharing is based
upon each company's "member-load-ratio," which is calculated monthly on the
basis of each company's maximum peak demand in relation to the sum of the
maximum peak demands of all five companies during the preceding 12 months. Since
1995, APCo, CSPCo, I&M, KPCo and OPCo have been parties to the AEP System
Interim Allowance Agreement which provides, among other things, for the transfer
of SO2 allowances associated with transactions under the Interconnection
Agreement.

       The following table shows the net credits or (charges) allocated among
the parties under the Interconnection Agreement and Interim Allowance Agreement
during the years ended December 31, 1995, 1996 and 1997.

       AEP is a member of ECAR. ECAR's membership includes 29 major electricity
suppliers located in nine states serving more than 36 million people. Membership
is voluntary, and the current full members are those utilities whose generation
and transmission have an impact on the


                                                                              25

reliability of the interconnected electric systems in the region. ECAR members
interchange power and energy with one another on a firm, economy and emergency
basis.

       As of December 31, 1997, the AEP System was interconnected through 120
high-voltage transmission interconnections with 26 neighboring electric utility
systems. The all-time and 1997 one-hour peak system demands were 25,940,000 and
24,485,000 kilowatts, respectively (which included 7,314,000 and 4,400,000
kilowatts, respectively, of scheduled deliveries to unaffiliated systems which
the AEP System might, on appropriate notice, have elected not to schedule for
delivery) and occurred on June 17, 1994 and January 17, 1997, respectively. The
net dependable capacity to serve the system load on such dates, including power
available under contractual obligations, was 23,457,000 and 23,669,000
kilowatts, respectively. The all-time and 1997 one-hour internal peak demands
were 19,557,000 and 19,381,000 kilowatts, respectively, and occurred on February
5, 1996 and January 17, 1997, respectively. The net dependable capacity to serve
the system load on such dates, including power dedicated under contractual
arrangements, was 23,765,000 and 23,669,000 kilowatts, respectively.

       APCo, CSPCo, I&M, KPCo and OPCo are parties to the Transmission
Equalization Agreement, dated April 1, 1984 (the "Transmission Agreement"),
which defines the method pursuant to which the parties share the costs
associated with their relative ownership of the extra-high-voltage transmission
system (which includes facilities rated 345 Kv and above) and certain facilities
operated at lower voltages (which includes facilities rated 138 Kv and above).
Like the Interconnection Agreement, sharing is based upon each company's
"member-load-ratio."

       Other assets owned by AEP include electric distribution systems located
throughout its service area, and property, plant and equipment owned or leased
supporting its electric utility functions.

       AEP also owns or leases other physical properties, including real
property, and other facilities necessary to conduct its operations.

Northeast Texas Electric Cooperative and Oklahoma Municipal Power Authority own
the rest of the interests in Dolet Hills.

(f)    SWEPCO owns 85.936% of Pirkey. Northeast Texas Electric Cooperative and
Oklahoma Municipal Power Authority own the rest of the interests in Pirkey.

(g)    SWEPCO owns half of Flint Creek and Arkansas Electric Cooperative
Corporation owns the other half.

(h)    WTU owns 54.7% of Oklaunion. (Non-affiliates own 12.29% of Oklaunion)

       All of the generating facilities described above are located on land
owned by CSW's U.S. electric utility subsidiaries or, in the case of jointly
owned facilities, jointly with other participants. The principal plants and
properties of CSW's electric utility subsidiaries are subject to liens of first
mortgage indentures under which CSW's electric utility subsidiaries' first
mortgage bonds are issued.

       As part of Applicants' proposed mitigation plan filed with the FERC,
Applicants agreed to divest 250 MW of capacity in ERCOT and 300 MW of generation
capacity in SPP. In the proceedings before the Texas Commission, Applicants
entered into a settlement with the staff of the Texas Commission under which
they agreed to divest 1604 MW of generation capacity in ERCOT (including the 250
MW of generating capacity contained in the proposed FERC mitigation plan). The
generation units subject to divestiture include Lon Hill Units 1-4 (CPL)--546
MW; Nueces Bay Plant (CPL)--559 MW; Joslin Unit 1 (CPL)--249 MW; Frontera Plant
(CSW Energy)--250 MW; and Northeastern Generating Plant (PSO)--300 MW. The
timing of divestiture of the generation capacity located in ERCOT and SPP is
conditioned upon there being no violation of the criteria for
pooling-of-interests accounting treatment of the Merger. If it is determined
that the ERCOT divestiture can proceed immediately after the Merger closes
without jeopardizing pooling-of-interests accounting treatment for the Merger,
sale of the plants would begin no later than 90 days after the Merger closes.
Absent that determination, the divestiture


                                                                              29
<PAGE>   30


would occur approximately two years after the Merger closes to satisfy the
requirements to use pooling-of-interests accounting treatment. The divestiture
of generation capacity located in SPP is also conditioned upon the plant no
longer being required to meet PSO's native load demand requirements following
electric industry restructuring in Oklahoma.

       In addition to the generating facilities described above, CSW has
ownership interests in nonutility electrical generating facilities. Information
concerning U.S. facilities is listed below.

       CPL, WTU, PSO, SWEPCO, and CSWS are parties to a Restated and Amended
Operating Agreement dated as of January 1, 1997 ("CSW Operating Agreement"). The
CSW Operating Agreement requires CSW's U.S. electric utility operating
subsidiaries to maintain specified annual planning reserve margins and requires
the subsidiaries that have capacity in excess of the required margins to make
such capacity available for sale to other subsidiaries as capacity commitments.
The CSW Operating Agreement also delegates to CSWS the authority to coordinate
the acquisition, disposition, planning, design and construction of CSW's
generating units and to supervise the operation and maintenance of a central
control center. CSWS, as agent for the CSW System, schedules the energy output
of the system capability to obtain the lowest cost of energy for serving
aggregate system demand and coordinates off-system purchases and sales. The CSW
Operating Agreement has been accepted for filing and allowed to become effective
by the FERC.

              (iii)  Electric Transmission and Other Facilities

       The following table sets forth the total circuit miles of transmission
and distribution lines of the CSW U.S. electric utility operating subsidiaries

           Total.  16,340         68,872

       CSW's U.S. electric utility subsidiaries' electric transmission and
distribution facilities are mostly located over or under highways, streets and
other public places or property owned by others, for which permits, grants,
easements or licenses have been obtained.

       CPL and WTU are members of ERCOT, which operates in Texas. Other ERCOT
members include Texas Utilities Electric Company, Houston Lighting & Power
Company, Texas Municipal Power Agency, Texas Municipal Power Pool, Lower
Colorado River Authority, the municipal systems of San Antonio, Austin and
Brownsville, the South Texas and Medina Electric Cooperatives, and several other
interconnected systems and cooperatives. PSO and SWEPCO are members of the SPP,
which includes 18 investor-owned utilities, 11 municipalities, 11 cooperatives,
3 state and 1 federal agency as well as IPPs and power marketers operating in
the states of Arkansas, Kansas, Louisiana, Oklahoma and parts of Mississippi,
Missouri, New Mexico and Texas. ERCOT members interchange power and energy with
one another on a firm, economy and emergency basis, as do the members of the
SPP.

       The highest all-time maximum coincident system demand through 1997 was
13,105 MW on July 28, 1997. The 1997 net dependable capacity to serve the system
load was 14,290 MW. Power generation at the time of the peak was 12,817 MW and
net purchases at the time of the peak were 288 MW. CPL, WTU, PSO, SWEPCO and
CSWS are parties to a Transmission Coordination Agreement dated as of January 1,
1997 ("TCA"). The TCA establishes a coordinating committee, which is charged
with the responsibility of overseeing the coordinated planning of the
transmission facilities of CSW's U.S. electric utility operating subsidiaries,
including the performance of transmission planning studies, the interaction of
such subsidiaries with ISOs and other regional bodies interested in transmission
planning and compliance with the terms of the OATT filed with the FERC and the
rules of the FERC relating to such tariff. Under the TCA, CSW's U.S. electric
utility subsidiaries have delegated to CSWS the responsibility of monitoring the
reliability of their transmission systems and administering the OATT on their
behalf. The TCA also provides for the allocation among CSW's U.S. electric
utility operating subsidiaries of revenues collected for transmission and
ancillary services provided under the OATT. The TCA has been accepted for filing
by the FERC effective as of January 1, 1997, and is the subject of proceedings
commenced to consider the reasonableness of its terms and conditions.

       CSW's average cost of fuel per million BTUs for the calendar years ended
December 31, 1995, 1996, and 1997 was 158 cents, 181 cents and 183 cents,
respectively.

       3.     Electric Coordination

       The Combined System will be physically interconnected and economically
operated as a single interconnected and coordinated system. Upon implementation
of the System Integration Agreement and the System Transmission Integration
Agreement and through the use of Central Dispatch Planning and Central Economic
Dispatch, the Combined System will have a central dispatch system capable of
scheduling the generating resources of the Combined System on an economical,
real-time basis. The Combined System will be physically interconnected through
the 250 MW Contract Path. Each aspect of the electric coordination and
interconnection of the Combined System is discussed below:

       a.     System Integration Agreement and System Transmission Integration
Agreement.

       The System Integration Agreement provides for the coordination of
generation within the Combined System. The System Transmission Integration
Agreement provides for the coordination of transmission within the Combined
System. The agreements, each of which will take effect upon consummation of the
Merger, are described in the Testimony of J. Craig Baker and Dennis W. Bethel
before the FERC which are filed with Exhibit D-1.1 and incorporated by
reference. The agreements and their functions are summarized below.

       As noted, the System Integration Agreement provides for the coordination
of generation within the Combined System. AEPSC will coordinate the planning,
operation and maintenance of generating capacity resources and the dispatch of
electricity throughout the Combined System. The coordination of generation is
accomplished through two computer software programs: Central Dispatch Planning
and Central Economic Dispatch. Central Dispatch Planning forecasts (usually on a
day-ahead basis, although sometimes several days ahead) the generation needs of
the Combined System and determines the least-cost allocation of generation
resources available within the Combined System necessary to meet the forecasted
obligations. The central dispatch


                                                                              32
<PAGE>   33


is based on anticipated fuel costs, load levels, wholesale power market
conditions, planned unit maintenance (which units are out of service or
operating below normal operating limits), and prevailing transmission
capabilities (including capacity reserved by third parties). During the morning
of normal working days (Monday through Friday), Central Dispatch Planning will
have scheduled hourly the following day's generation for every unit in the
Combined System (with the exception of Friday, when generation is scheduled for
Saturday, Sunday and Monday).

       Central Economic Dispatch computes at regular intervals (currently every
four seconds) the most economic generation dispatch base points resulting from
current operating obligations. While Central Dispatch Planning is based on
predictive conditions, Central Economic Dispatch is a real-time function that
continuously evaluates current operating conditions, and, based on least-cost
allocations and existing transmission constraints, issues new dispatch
instructions to each generating unit within the Combined System.

       Central Dispatch Planning and Central Economic Dispatch will be ready to
serve the Combined System prior to the effectiveness of the Merger, and,
accordingly, each will be available to the Combined System immediately upon
consummation of the Merger. Each will utilize the existing electronic
communication infrastructures currently in place in each of the AEP System and
the CSW System. The existing electronic communication infrastructures will feed
data to, and receive instructions from, Central Dispatch Planning and Central
Economic Dispatch via a high speed data link.

       The System Transmission Integration Agreement provides for the
coordinated planning, operation and maintenance of the Combined System's
transmission facilities and the assignment among the Combined System's operating
companies of third-party transmission costs incurred to coordinate post-Merger
operations. AEPSC will coordinate the planning, operation and maintenance of
transmission facilities and capacity of the Combined System. The Combined System
will be subject to regulation by the FERC with respect to transmission and the
Combined System intends to operate in full compliance with all applicable FERC
rules and orders regarding, among other things, tariffs, billing and revenue
allocation, immediately upon the consummation of the Merger. In this regard, the
Applicants have entered into a stipulation with FERC Trial Staff resolving all
issues between them regarding the System Integration Agreement, the Transmission
Reassignment Tariff, and the System Transmission Integration Agreement. The
Stipulation with FERC Trial Staff is filed as Exhibit D-1.4 and incorporated by
reference.

       b.     250 MW Contract Path

       The Combined Company will transmit power from east to west over the 250
MW Contract Path. The 250 MW Contract Path's term is from June 1, 1999 to May
31, 2003, which may be renewed through the Ameren OATT. AEPSC will coordinate
the planning of the transmission capacity interconnecting the Combined System.

       In order to increase its firm transmission service rights on the MOKANOK
Line, CSW's subsidiary, PSO, entered into an agreement with WR to provide firm
point-to-point transmission service for the transfer of 38 MW of power from
Ameren. The point of receipt and delivery for the 38 MW of power will be the
point of interface with Ameren and WR's and PSO's undivided interest in the
MOKANOK Line. PSO and another CSW subsidiary, SWEPCO, will transmit the


                                                                              33
<PAGE>   34


38 MW of power from the interface between PSO's and WR's undivided interest in
the MOKANOK Line to PSO's 345 Kv bus at its Northeastern Generating Station. PSO
will transmit the remaining 212 MW of power over its undivided interest in the
MOKANOK Line from the interconnection with Ameren on the MOKANOK Line to PSO's
345 Kv bus at its Northeastern Generating Station. In order to enable the 250 MW
Contract Path to accommodate a 250 MW firm transfer, CSW and Ameren agreed that
Ameren would upgrade Ameren's Albion Substation in order to increase available
transfer capability into Ameren from the east during the summer peak period. The
upgrade, effected by installing a 138 Kv reactor, was completed on August 1,
1998.

       Applicants have committed to avoid any possible anticompetitive concerns
attributable to the Merger by agreeing to limit their reservation of firm
transmission service from east to west to 250 MW unless the FERC authorizes them
to go above this limit. See Dr. William Hieronymus' testimony filed as an
exhibit to Exhibit D-1.2 and incorporated herein by reference.

       c.     Additional Power Transfers

       The Applicants expect that from time to time there will be opportunity to
transfer energy economically in the Combined Company from west to east. In these
circumstances, Applicants will make use of their rights to nominate secondary
points of receipt and delivery under their transmission service agreements with
WR and Ameren. PSO has the right to transfer approximately 113 MW of energy on a
non-firm basis across the MOKANOK Line. Ameren's OASIS postings indicate that
there are more than 1000 MW of transfer capability across the Ameren system from
the MOKANOK Line to the east.

       In addition to the use of the 250 MW Contract Path, quantities in excess
of the 250 MW can be moved within the Combined System in any given hour by using
non-firm transmission rights. Such additional transfers would be made when
circumstances indicate that they would be economical for post-Merger system
operations after taking into consideration opportunity costs. See generally,
Testimony of J. Craig Baker, filed with Exhibit D-1.1 and incorporated herein by
reference.

       As part of the FERC Stipulation, Applicants agreed to waive the Combined
Company's priority with respect to its use of the HVDC ties for unplanned (i.e.,
non-firm) transactions in ERCOT and non-firm transactions in the SPP. See
Exhibit D-1.2, Supplemental Testimony of Stephen Jones at 15-17. This waiver of
priority would not apply to planned (i.e., firm) transactions that are submitted
to ERCOT or other transfers of firm capacity between the Applicants' SPP and
ERCOT control areas, including the use of the North HVDC tie to export the
output of the Oklaunion generation station to PSO and to Oklahoma Municipal
Power Authority, both located in the SPP.(1) Thus, the Applicants would continue
to use the HVDC ties

- -----------------------

       (1)    CSW's firm transmission capacity has always been adequate to
integrate its operations, and there has never been a need to assert a priority
for unplanned transactions over the HVDC ties. As a general matter, the HVDC
ties are available and are not typically constrained. In fact, CSW has the only
existing reservation on the North HVDC tie, and there are no reservations on the
East HVDC tie after the summer of 1999. As a result, Applicants do not expect
their waiver of priority for non-firm use of the HVDC ties to affect the
integration of their system in any manner.


                                                                              34
<PAGE>   35


to integrate CSW's Texas assets with its non-Texas assets in the same manner
that previously has been approved by the Commission.

       d.     Future Participation in an RTO

       On June 3, 1999, AEP and four other utilities filed the Alliance RTO
Application, which is currently pending at FERC. CSW is participating in the
ERCOT independent regional transmission plan for the portion of its system that
is within ERCOT and is participating in discussions with other interested
parties about the formation of an RTO that would include its utility systems
located in the SPP.(2) Participation in these RTOs will enhance system
reliability after the Merger as described below.

       The Applicants' goal ultimately is to further enhance the reliability of
the Combined System through participation in a regional RTO. RTOs provide
strengthened assurances to the marketplace that transmission service will be
available to all eligible customers on a non-discriminatory basis. In addition,
RTOs can enhance regional reliability and, if properly structured and
configured, improve economic efficiencies and provide access to a broad range of
buyers and sellers across a large geographic region.

       Until such time as the Combined Company transfers certain control area
functions related principally to reliability and access to one or more RTOs, all
facets of the centralized coordination of the transmission facilities of the
Combined Company's system will be accomplished through the System Transmission
Integration Agreement. At such time as AEP transfers to the RTO certain control
area operations relating principally to system reliability and access, the
remaining functions of the Combined Company's transmission system will continue
to be coordinated through the System Integration Transmission Agreement.

       Participation in RTOs can enhance the reliability of the Combined
Company's system in several ways. In the Notice of Proposed Rulemaking regarding
RTOs,(3) FERC found that an RTO would improve efficiencies in the management of
the transmission grid (RTO NOPR mimeo at 90); would improve grid reliability
(RTO NOPR mimeo at 95); would improve market performance (RTO NOPR mimeo at 98);
and would facilitate lighter governmental regulation (RTO NOPR mimeo at 101). It
is FERC's view that all utilities should participate in a FERC-approved RTO.

- -----------------------

       (2)    In the order of the Oklahoma Commission approving the Merger, AEP
is required to file with the FERC, not later than six months before retail
competition commences in the State, or December 31, 2001, an application to,
transfer the operational control of bulk transmission facilities owned,
controlled and/or operated by AEP that are currently located in the SPP to a
FERC-approved RTO that is directly interconnected with the AEP system. See
Exhibit 4.2, at 17.

       C.     DESCRIPTION OF MERGER AND STATEMENT AS TO CONSIDERATION

          1.     Background of the Merger

       AEP and CSW are seeking to merge to further their mutual strategy of
adapting to an era of historic changes in the electric utility industry. The
electric utility industry is in the process of a transformation to greater
levels of competition in the wholesale and retail energy markets. Technological
advances, consumer pressures and federal and state legislative and regulatory
initiatives are forces affecting this transformation. Efficient, low cost
suppliers of energy with a diverse customer base will be best prepared to
compete successfully in the resulting electric energy marketplace.

       Historically, competition in the wholesale and retail electric energy
markets was limited. In the wholesale market, this limitation was due to various
barriers to entry, including the difficulties in obtaining transmission service
over utility systems located between potential buyers and sellers and the
possibility of regulation under the 1935 Act. Pursuant to the Energy Act,
however, Congress authorized the FERC to exempt certain wholesale power sellers
from regulation under the 1935 Act. In 1996, the FERC issued Orders 888 and 889
requiring utilities to provide non-discriminatory, open-access transmission
service upon request. These regulatory developments have resulted in an active,
competitive wholesale market for electricity. Although the retail market for
electricity currently is less developed than the wholesale market, most states
in which the electric utility operating subsidiaries of AEP and CSW provide
retail service have adopted or are actively considering legislative or
regulatory action permitting retail customers to select their electricity
supplier and obligating utilities to provide transmission and distribution
service to competitors. Because of these ongoing legislative and regulatory
activities, the managements of AEP and CSW have concluded that there will soon
be increased competition in the retail sector of the business.

       Electric utility companies must adapt quickly to this evolving
competitive environment if they are to succeed in it. Many companies are
pursuing consolidation to diversify business risks and create new opportunities
for earnings growth. Assets, such as a utility's transmission network and low
cost generation, will be key factors in structuring the successful electric
utility of the future. Customers in a competitive market will choose electric
suppliers that are efficient and responsive.

       For the past several years, AEP and CSW separately have been focusing
their strategic planning activities on preparing for this fundamental evolution.
AEP and CSW have now determined that a merger of the two companies is the best
way to achieve their compatible long-term goals.

          2.     Merger Agreement

       The following is not a complete description of the Merger Agreement and
is qualified in its entirety by reference to the Merger Agreement, which is
attached and incorporated by reference as Exhibit B-l.

       The Merger Agreement provides for a business combination of AEP and CSW
in which Merger Sub will be merged with and into CSW. CSW will be the surviving
corporation and will


                                                                              36

become a wholly-owned subsidiary of AEP. Upon the consummation of the Merger,
each issued and outstanding share of CSW Common Stock (other than the Excluded
Shares) will be exchangeable for 0.60 shares of AEP Common Stock. Based on the
price of AEP Common Stock on December 19, 1997, the transaction would be valued
at $6.6 billion. Each issued and outstanding share of AEP Common Stock will be
unchanged as a result of the Merger.

       The former holders of CSW Common Stock will own approximately 40% of the
issued and outstanding AEP Common Stock after the Merger. The Merger is subject
to customary closing conditions, including the receipt of all necessary
governmental approvals, including the approval of the Commission. The Merger is
designed to qualify as a tax-free reorganization under Section 368(a) of the
Internal Revenue Code of 1986, as amended, and will be treated as a
"pooling-of-interests" for accounting purposes.

          3.     Reasons for the Merger

       The Merger offers significant opportunities to create additional value
for shareholders, customers and employees of the Combined Company. The benefits
of the Merger include the following:

- -      COST SAVINGS - The Combined Company will be more efficient than either
company standing alone. Merging will allow the companies to create efficiencies
in operations and business processes, eliminate duplicative functions, enhance
their purchasing power, and combine two workforces. The Combined Company should
realize Merger-related non-fuel savings of nearly $2 billion over the first ten
years following the Merger, net of transaction and transition costs, and net
fuel-related savings of approximately $98 million over the same period.

- -      COMPETITIVE PRICES AND SERVICES - The Combined Company will use the
efficiencies arising from the Merger to compete effectively in the increasingly
competitive marketplace. Sales to industrial, large commercial and wholesale
customers are at greatest near-term exposure to increased competition; these
customers will choose among potential suppliers those best able to meet their
demands for reliable, low-cost power. The Merger will enable the Combined
Company to serve customers more efficiently and effectively.

- -      FINANCIAL STRENGTH - By combining the market capitalization of the
individual companies, the Merger will result in a Combined Company with a
stronger financial base, improved position in the credit markets, and greater
market diversity.

- -      GREATER DIVERSIFICATION - The combination of AEP and CSW will diversify
the Combined System's service territory, reducing exposure to adverse changes in
any sector's economic and competitive conditions. The Combined Company will
expand relationships with existing customers and develop relationships with new
customers in its service area, using its combined distribution channels to
market a portfolio of innovative energy-related products at competitive prices.
The Merger will result in a Combined Company with more diversity in fuel and
generation, which will reduce dependence upon any one sector of the energy
industry and exposure to fluctuations in certain commodity prices.

- -      INCREASED SCALE - As competition intensifies within the industry, scale
will be one contributor to overall business success. Scale is important in many
areas, including utility


                                                                              37
<PAGE>   38


operations, product development, advertising and corporate services.
Profitability of the Combined Company will be enhanced by the expanded customer
base and the synergies in all of these areas.

          4.     AEP Management Following the Merger

       The Board of Directors of the Combined Company immediately following the
Merger will consist of 15 members and will be reconstituted to include all
then-current board members of AEP, Mr. E. R. Brooks (the current Chairman of
CSW) and four additional outside directors of CSW to be nominated by AEP. Dr. E.
L. Draper, Jr., will be the Chairman and Chief Executive Officer of the Combined
Company. The Merger Agreement also provides that, from and after its
effectiveness, the Combined Company's corporate headquarters will be located in
Columbus, Ohio.

</TABLE>

       Section 9(a)(1) of the 1935 Act provides that unless the acquisition has
been approved by the Commission under Section 10, it shall be unlawful for any
registered holding company or any subsidiary company thereof "to acquire,
directly or indirectly, any securities or utility assets or any other interest
in any business." Section 9(a)(1) is applicable to the proposed Merger because
the transaction involves the acquisition by AEP of CSW Common Stock and the
Merger Sub common stock, and the indirect acquisition of the securities of and
interests in the businesses of CSW's subsidiary companies.

       As set forth more fully below, the Merger fully complies with Section 10
of the 1935 Act:

- -      The Merger will not create detrimental interlocking relations or a
       detrimental concentration of control;

- -      The consideration and fees to be paid in the Merger are fair and
       reasonable;

- -      The Merger will not result in an unduly complicated capital structure for
       the Combined Company;

- -      The Merger is in the public interest and the interests of investors and
       consumers;

- -      The Combined System will be a single integrated public utility system;

- -      The Merger equitably distributes voting power among the investors in the
       Combined Company and does not unduly complicate the structure of the
       holding company system;


                                                                              39
<PAGE>   40


- -      The Merger tends toward the economical and efficient development of an
       integrated electric utility system; and

- -      The Merger will comply with all applicable state laws.

       Under Sections 9 and 10, Congress gave the Commission the responsibility
for "supervision over the future development of utility-holding company
systems." The Southern Co., HCAR No. 25639 (Sept. 22, 1992) (citations omitted)
[hereinafter "Southern"]. Section 1(c) of the 1935 Act directs the Commission to
interpret all provisions of the 1935 Act to meet the problems and eliminate the
evils set forth in the 1935 Act in order to protect the interests of investors,
consumers and the general public. Accordingly, the Commission's mandate under
these sections is "to prevent acquisitions which would be 'attended by the evils
which have featured the past growth of holding companies.'" American Elec. Power
Co., HCAR No. 20633 (July 21, 1978) (quoting H.R. Rep. No. 1318, 74th Cong., 1st
Sess. 16 (1935)) [hereinafter "AEP"]. These evils include the "growth and
extension of holding companies [that] bears no relation to economy of management
and operation or the integration and coordination of related operating
properties." Section 1(b)(4) of the 1935 Act.

       As the Supreme Court has recognized, the 1935 Act is an "intricate
statutory scheme" which must be given "practical sense and application." SEC v.
New England Elec. Sys., 384 U.S. 176 (1966), rev'g and remanding 346 F.2d 399
(1st Cir. 1966), rev'g, New England Elec. Sys., 41 SEC 888 (1964), on remand,
376 F.2d 107 (1st Cir. 1967), rev'd, 390 U.S. 207 (1968). In administering the
1935 Act, the Commission must "weigh policies [of the 1935 Act] against each
other and against the needs of particular situations." Union Elec. Co., HCAR No.
18368 (Apr. 10, 1974), aff'd sub nom. City of Cape Girardeau v. SEC, 521 F.2d
324 (D.C. Cir. 1975) (citation omitted) [hereinafter "Union Electric"]. The
Commission is not disposed to "apply concepts such as res judicata or stare
decisis to the essentially regulatory and policy determinations called for in a
Holding Company Act case . . . ." AEP, supra. In considering whether to approve
an acquisition, the Commission "must make that determination in light of
contemporary circumstances . . . and [its] present view of the Act's
requirements." Southern, supra (citations omitted).

       The Merger complies with the 1935 Act. In light of contemporary
circumstances, the Merger does not result in any of the concerns the 1935 Act
was intended to address. In this regard, the Merger will benefit the public
interest and the interests of investors and consumers. Adequate safeguards,
through both state and federal regulation, ensure that the public interest and
the interests of investors and consumers continue to be protected. Approval of
the Merger is consistent with previous merger transactions approved by the
Commission under the 1935 Act. Each subsection of Section 10 of the 1935 Act is
addressed below, as well as the public policies underlying the 1935 Act, as they
relate to the Merger.

       A.     SECTION 10(b)

       Section 10(b) of the 1935 Act provides that, if the requirements of
Section 10(f) are satisfied, the Commission shall approve an acquisition under
Section 9(a) unless:


                                                                              40
<PAGE>   41

       (1)    such acquisition will tend towards interlocking relations or the
              concentration of control of public utility companies, of a kind or
              to an extent detrimental to the public interest or the interest of
              investors or consumers;

       (2)    in case of the acquisition of securities or utility assets, the
              consideration, including all fees, commissions, and other
              remuneration, to whosoever paid, to be given, directly or
              indirectly, in connection with such acquisition is not reasonable
              or does not bear a fair relation to the sums invested in or the
              earning capacity of the utility assets to be acquired or the
              utility assets underlying the securities to be acquired; or

       (3)    such acquisition will unduly complicate the capital structure of
              the holding company system of the applicant or will be detrimental
              to the public interest or the interest of investors or consumers
              or the proper functioning of such holding company system.

           1.  Section 10(b)(1)

       Section 10(b)(1) of the 1935 Act requires the Commission to approve a
proposed acquisition unless it finds that the proposed acquisition will "tend
towards interlocking relations or the concentration of control of public utility
companies of a kind or to an extent detrimental to the public interest or the
interest of investors or consumers." As this Section clearly indicates, a merger
does not run afoul of Section 10(b)(1) merely because it causes interlocking
relations or a concentration of control. Rather, a merger will fail the
balancing test set forth in this Section only when the detrimental effects, if
any, from any such interlocking relations or concentration of control caused by
the merger outweigh the benefits of the merger.

              a. Interlocking Relations

       By its nature, any merger results in interlocking relations between
previously unrelated companies. As the Commission has previously noted: "[W]ith
any addition of a new subsidiary to a holding company system, the Acquisition
will result in certain interlocking relationships between [the two merging
entities]." Northeast Utilities, HCAR No. 25221 (Dec. 21, 1990), modified on
other grounds, HCAR No. 25273 (Mar. 15, 1991), aff'd sub nom. City of Holyoke
Gas & Elec. Dep't v. SEC, 972 F.2d 358 (D.C. Cir. 1992) (citation omitted).
[hereinafter "Northeast I"]. Such "interlocking relationships are necessary to
integrate [the two merging entities.]" Id.

       The Merger Agreement provides for the Board of Directors of the Combined
Company to be composed of members drawn from the Boards of Directors of both AEP
and CSW. Specifically, the Board of Directors of the Combined Company will
consist of 15 members including the current Chairman of the Board of CSW and
four other outside directors of CSW to be nominated by AEP. This combined Board
of Directors for the Combined Company is necessary to assure the effective
integration and operation of the Combined Company. As discussed below in Item
3.B.2, the Merger will result in benefits to the public interest and the
interests of investors and consumers. As such, the interlocking relations do not
harm, but rather, promote the interests which Section 10(b)(1) is meant to
protect.



                                                                              41
<PAGE>   42

              b. Concentration of Control

       Under the Section 10(b)(1) concentration of control test, the Commission
"considers various factors, including the size of the resulting system and the
competitive effects of the acquisition." Entergy Corp., HCAR No. 25952 (Dec. 17,
1993), request for reconsideration denied, HCAR No. 26037 (Apr. 28, 1994),
remanded sub nom. Cajun Elec. Power Coop. Inc. v. SEC, 1994 WL 704047 (D.C. Cir.
Nov. 16, 1994) (citations omitted). [hereinafter "Entergy"]. These factors are
discussed below.

                 (i) Size

       As the terms of Section 10(b)(1) dictate and as the Commission has
recognized, Section 10(b)(1) does not "impose any precise limits on holding
company growth." AEP, supra. Congress condemned the "growth and extension of
holding companies [that] bears no relation to economy of management and
operation or the integration and coordination of related operating properties."
Section 1(b)(4) of the 1935 Act. The Commission has rejected a mechanical size
analysis under Section 10(b)(1) in favor of assessing the size of the resulting
system as it relates to the efficiencies and economies that can be achieved
through the integration and coordination of the new system's utility operations.
Entergy, supra (rejecting "conclusory assertions that the combined systems would
be too large to satisfy [Section 10(b)(1)]" and finding that merger created a
"large system, but not one that exceeds the economies of scale of current
electrical generation and transmission technology.") Section 10(b)(1) allows the
Commission to "exercise its best judgment as to the maximum size of a holding
company in a particular area, considering the state of the art and the area or
region affected." AEP, supra. Other recent transactions confirm that the
Commission evaluates the resulting size of a merging entity in terms of the
overall effects of the merger. For example, in Centerior Energy Corp., HCAR No.
24073 (Apr. 29, 1986) [hereinafter "Centerior"], the Commission stated that a
"determination of whether to prohibit enlargement of a system by acquisition is
to be made on the basis of all the circumstances, not on the basis of size
alone." See also, Northeast I, supra (applying standard articulated in
Centerior, supra, to find acquisition satisfied Section 10(b)(1)). Likewise, the
Division recommended in its 1995 Report that the Commission approach its
analysis of merger and acquisition transactions in a flexible manner with an
emphasis on whether the transaction creates an entity subject to effective
regulation and results in economies and efficiencies as opposed to focusing on
rigid, mechanical tests. 1995 Report at 66-70.

       In short, size alone is not suspect. Rather, as the 1935 Act provides,
the concern is an enlargement of the system that is "of a kind or to an extent
detrimental to the public interest or the interest of investors or consumers"
caused "by the growth and extension of holding companies [that] bears no
relation to economy of management and operation or the integration and
coordination of related operating properties." Sections 10(b)(1) and 1(b)(4) of
the 1935 Act.

       For purposes of comparison, the table below provides certain operating
information derived from publicly available documents for a selected group of
public utility systems. Each public utility system, with the exception of CSW,
consistently ranks at or near the top of virtually all categories presented.
These data identify and rank the largest public utility systems in the United
States. Among the utilities presented, AEP currently ranges from the second to
the fifth largest public utility system in the United States depending on the
criterion of measurement.



                                                                              42
<PAGE>   43

Giving effect to the Merger as of December 31, 1997, on a pro forma basis, the
Combined Company would have ranged from the largest to the fourth largest public
utility system in the United States, again depending on the criterion of
measurement.

       Combined Company upon completion of the Merger.

       The table above does not reflect Applicants' agreement, as part of the
Texas settlement, to divest 1604 MW of generation capacity in ERCOT and, as part
of Applicants' FERC mitigation plan, to divest 300 MW of generation capacity in
SPP. Even without taking into account these divestitures of generation capacity,
the data show that, as of December 31, 1997, Southern and PG&E would have been
larger than the Combined Company in total assets; Duke, Southern, and PG&E would
have been larger than the Combined Company in terms of operating revenues; and
Duke and Southern would have been larger than the Combined Company in total
market capitalization. Thus, the data show that the Combined Company will be
comparable in size to other large public utility systems.

       Moreover, the size of the Combined Company would not cause a
concentration of control within the relevant region under existing Commission
precedent. In Northeast I, supra, the Commission approved a merger in which the
combined system would have 29% of the peak load capacity, 36.7% of the total
assets and less than one-third of the operating revenues, number of electric
customers and KwH sales when compared to the regional electric utility industry.
The Commission further noted that these figures were well below the 40% level
that would have resulted in the merger the Commission blocked for other reasons
in New England Elec. Sys., HCAR No. 18801 (Feb. 4, 1975) ("NEES Decision"). Id.
at n. 53 (when measured by operating revenues, number of electric customers, KwH
sales, KwH capacity and electric power generated in KwH, the combined companies
in the NEES Decision would have represented "about 40% of New England").



                                                                              43

       Applicants propose that the relevant region for evaluating the size of
the Combined Company should include the Combined Company and those electric
utilities directly interconnected with AEP and/or CSW ('Interconnected
Utilities').(4) See Entergy, supra (Commission adopted the applicants'
definition of the relevant region for purposes of measuring size to include
applicants and those electric utilities directly interconnected with either or
both). As the table below indicates, the size of the Combined Company compared
to the size of the Interconnected Utilities and the Combined Company varies from
10 percent to 16 percent depending on the criterion of measurement. Further, if
data from the Applicants' historical wholesale customers are added to these
Interconnected Utilities data (the sum equaling the relevant destination markets
for purposes of measuring market power as described in the testimony of Dr.
Hieronymus before the FERC, attached as exhibits to Exhibits D-1.1 and D-1.2 and
summarized in Item 3.A.1.b.(ii)., 'Antitrust Considerations', infra), then the
size of the Combined Company as a percentage of the destination markets
identified by Dr. Hieronymus is even smaller.

       distributor customers and Southwestern Power Administration has 92
       customers comprised of municipalities, federal agencies and cooperatives.

Sources:                Edison Electric Institute, Electrical Utility Data,
                        EZStat Query System (1996); EIA Publication-Financial
                        Statistics of Major US Investor-Owned Electric Utilities
                        (1996); EIA Publication Financial Statistics of Major US
                        Publicly-Owned Electric Utilities (1996).

       Specifically, as the table above indicates, at December 31, 1996, the
Combined Company would have represented no more than the following percentages
of the utility industry in the region, in terms of the above criteria: net
electric plant (10%); electric revenues (12%); number of electric customers
(15%); MwH sales (14%); and net generation (16%). As such, the size of the
Combined Company relative to the relevant region is significantly below the 40%
threshold previously cited by the Commission. In fact, two of these percentages
would be even less if the data reflected Applicants' agreement, as part of the
Texas settlement, to divest 1604 MW of generation capacity in ERCOT and, as part
of Applicants' FERC mitigation plan, to divest 300 MW of generation capacity in
SPP.

       By definition, any merger creates an entity larger than each of the
constituent parts. However, the size of the Combined Company will not exceed the
economies of scale of current electrical generation and transmission technology
and, therefore, does not exceed the maximum size of a holding company
considering the "state of the art." Technological changes have resulted in power
being transmitted over greater distances with less line loss, single integrated
computer networks that more efficiently dispatch generation sources and control
constricted transmission areas, and generation technologies that have reduced
the cost of power and increased the flexibility of power plant siting. Moreover,
changes in the regulatory and legal framework have resulted in an increase in
non-utility generators, non-utility marketers and brokers. Together, these
technological, legal and regulatory changes have resulted in increased
competition within the industry.(5) Given these present realities, the size of
the Combined System will not result in a "concentration of control" of a kind or
to an extent detrimental to the interests of the public, investors or consumers.
As described in detail below in Item 3.B.2, the Merger is expected to yield
significant economies and efficiencies. Net non-production savings of nearly $2
billion and net fuel-related savings of approximately $98 million are projected
over the first ten years. These savings will be realized by investors and
customers.

                 (ii) Antitrust Considerations

       The Commission's analysis under Section 10(b)(1) also includes a
consideration of federal antitrust policies.(6) If the Commission determines
that an acquisition will tend towards the concentration of control of public
utility companies, it balances this effect against the benefits from the
acquisition to determine whether the acquisition passes the Section 10(b)(1)
balancing test. The Commission "has approved acquisitions that decrease
competition when it concludes

- -------------------------

       (5) The "state of the art" is discussed in depth in Item 3.B.1.a below.

       (6) See, e.g., Conectiv, HCAR No. 26832 (Feb. 25, 1998) [hereinafter
"Conectiv"].


                                                                              45
<PAGE>   46

that the acquisitions would result in benefits such as possible economies of
scale, elimination of the duplication of facilities and activities, sharing of
production capacity and reserves, and generally more efficient operations."
Northeast I, supra. The Commission has also explained that the "antitrust
ramifications of an acquisition must be considered in light of the fact that
public utilities are regulated monopolies and that federal and state
administrative agencies regulate the rates charged consumers." Id.

       When assessing the possible anticompetitive effects of a proposed
acquisition, the Commission is --

       primarily concerned with the structure of public utility holding company
       systems. The Commission, however, has also considered anticompetitive
       issues involving the allocation of excess generating capacity,
       transmission access and the flow of electricity over transmission lines
       of a holding company system.

Entergy, supra (citations omitted).

       The FERC has jurisdiction over the Merger under Section 203 of the FPA.
It will make a finding as to whether the Merger is consistent with the public
interest based, in part, upon consideration of the anticompetitive consequences,
if any, of the proposed transaction. The Commission has relied upon the
expertise of other federal regulators in determining the anticompetitive effects
of proposed merger transactions, and the D.C. Circuit has upheld the
Commission's ability to watchfully defer to other regulators:

       [W]hen the SEC and another regulatory agency both have jurisdiction over
       a particular transaction, the SEC may 'watchfully defer[]' to the
       proceedings held before -- and the result reached by -- that other
       agency.

Madison Gas & Elec. Co. v. SEC, 168 F.3d 1337, 1341-42 (D.C. 1999), citing City
of Holyoke Gas & Elec. Dep't v. SEC, 972 F.2d 358 (D.C. Cir. 1992) (dismissing
challenge to order approving merger that asserted Commission could not rely on
FERC and state review of competitive effects) [hereinafter "Madison Gas"].
Consistent with the foregoing, the Division in its 1995 Report recommended that
"the SEC avoid duplicative review of acquisitions and, where possible, defer to
the work of other regulators in reviewing acquisitions." 1995 Report at 66. In
this case, the SEC can watchfully defer to other agencies (namely, the DOJ and
the FERC) on the question of competitive issues because consummation of the
Merger may not take place until and unless potential competitive concerns have
been addressed by these agencies under the HSR Act procedures as well as under
Section 203 of the FPA. If the Commission determines to approve the Merger
(subject to the FERC's approval of the Merger and/or the DOJ's lack of challenge
to the transaction), it can defer to these agencies even if their proceedings
are not yet complete because the Commission retains ongoing authority under
Section 20(a) of the 1935 Act to rescind or further condition its approval of a
transaction. Id.

                 ii(a). The Role of the DOJ

       Pursuant to the HSR Act, AEP and CSW are required to file with the DOJ
Premerger Notification and Report Forms. See 16 C.F.R. Parts 801 through 803.
The purpose of the HSR Act reporting requirements is to "facilitate evaluation
of the antitrust implications of the



                                                                              46
<PAGE>   47

proposed transaction and, where the competitive consequences appear substantial,
to permit the DOJ to challenge the legality of the transaction."(7) The HSR Act
prohibits consummation of the Merger until the statutory waiting period has
expired or been terminated. In July 1999, Applicants filed with the DOJ under
the HSR Act.

                 ii(b). The Role of the FERC

       AEP and CSW filed a joint application with the FERC on April 30, 1998,
(see Exhibit D-1.1 filed herewith), as supplemented on January 13, 1999, (see
Exhibit D-1.2 filed herewith), pursuant to Section 203 of the FPA for approval
of the Merger. Applicants and the FERC Trial Staff entered into the FERC
Stipulation under which major issues related to the Merger were resolved,
including all significant competition and rate issues (see Exhibit D-1.3 filed
herewith).

       The application, as supplemented, conformed to FERC Order No. 592 in
which the FERC adopted the DOJ/FTC Merger Guidelines as the framework for
analyzing the impact of a merger on competition in affected markets.(8) The
AEP/CSW application to the FERC contained testimony by Dr. William Hieronymus
analyzing the Merger pursuant to FERC Order No. 592. Copies of Dr. Hieronymus'
testimony are filed as exhibits to Exhibits D-1.1 and D-1.2. The analysis
presented therein measures the competitive effect of the Merger within the
relevant destination markets. Dr. Hieronymus concludes that, with the mitigation
measures which the Applicants propose as a condition of the Merger, the Merger
will not adversely affect competition in any of the destination markets that
were analyzed. Dr. Hieronymus' testimony is summarized below:

                 (x) Product Markets

       The FERC presumes the long-term capacity market to be competitive, unless
special factors exist that limit the ability of long-term capacity markets to
develop. The evidence demonstrates that the Combined Company will not control
transmission access, fuel supplies or generation plant sites. Accordingly, the
Combined Company will not have market power in long-term capacity markets.

       For the shorter term markets, the FERC applies a market screen analysis
to determine if a merger raises competitive concerns. For that purpose, the FERC
uses four product measures: 1) Total Capacity; 2) Uncommitted Capacity; 3)
Available Economic Capacity; and 4) Economic Capacity.

       With respect to the Total Capacity measure, the overall size of the
market will be in excess of 340,000 MW in 1999, growing to almost 360,000 MW in
2001. The Total Capacity of the Combined System is approximately 39,000 MW (less
the 1604 MW of generating assets

Association 1991).

       (8) Inquiry Concerning the Commission's Merger Policy under the Federal
Power Act: Policy Statement, Order No. 592, Docket No. RM96-6-000, Regulations
Preambles, Paragraph 31,044 at 30,109 (December 30, 1996).


                                                                              47
<PAGE>   48

located in ERCOT and 300 MW of generating assets located in SPP that Applicants
have agreed to divest). Applying the screening analysis, Dr. Hieronymus
concluded that the market is unconcentrated (an HHI of less than 1000) and,
accordingly, the Merger has no anti-competitive impact with respect to Total
Capacity.

       With respect to the Uncommitted Capacity measure, CSW Energy has 705 MW
of uncommitted capacity and AEP has 495 MW of uncommitted capacity. The
combination of the uncommitted capacity represents less than a 15 percent
combined market share. Dr. Hieronymus concluded that the market of Uncommitted
Capacity is unconcentrated and mergers in such markets are presumed to have no
anti-competitive impact.

       With respect to the Economic Capacity measure, Dr. Hieronymus concluded
that when the Applicants' mitigation proposal is taken into account, the Merger
significantly deconcentrates the CSW SPP and ERCOT markets and results in HHI
changes below the FERC Order 592 threshold in all but a handful of destination
markets. (The exceptions involve destination markets in which the Combined
Company will have a miniscule market share because the Applicants' use of the
250 MW Contract Path will serve to increase the already high market share of one
or more incumbent sellers that are unrelated to either Applicant.)

       With respect to the Available Economic Capacity measure, Dr. Hieronymus
concluded that, for the most part, CSW's SPP and ERCOT markets are
deconcentrated. The AEP market is either deconcentrated or reflects zero HHI
changes in all time periods. The HHI changes for almost all of the other
relevant destination markets and time periods are below the FERC Order No. 592
threshold or are zero or are negative (meaning that the market is
deconcentrated). The few exceptions are in destination markets in which the
Applicants have little or no post-merger market share.

       With the inclusion of the 250 MW Contract Path to interconnect the
Applicants' systems, a few additional failures under the screening analysis
resulted for the Economic Capacity Measure in the SPP and ERCOT markets. As to
those markets that did not fall below the minimum benchmark, Applicants, in
their application filed with the FERC, as supplemented, proposed mitigation
measures to offset any increase in market concentration so as to reduce the HHI
to fall within safe harbor levels. AEP and CSW propose to divest ownership of
550 MW of generation capacity (300 MW in the SPP and 250 MW in the ERCOT) by
means of auction. (As part of the settlement with the staff of the Texas
Commission, Applicants have now agreed to divest 1604 MW of generating assets
located in ERCOT, which includes the 250 MW of generating assets located in
ERCOT that will be divested as part of the proposed FERC mitigation measures).

       The auction process for the ERCOT and SPP generation capacity is
conditioned upon there being no violation of the pooling-of-interests accounting
treatment used for the Merger. If it is determined that the ERCOT divestiture
can proceed immediately after the Merger closes without jeopardizing
pooling-of-interests accounting treatment for the Merger, sale of the plants
would begin no later than 90 days after the Merger closes. Absent that
determination, the divestiture would occur approximately two years after the
Merger closes to satisfy the requirements to use pooling-of-interests accounting
treatment. The 300 MW of generation to be divested in SPP is also conditioned
upon the plant no longer being required to meet PSO's native



                                                                              48
<PAGE>   49

load demand requirements following electric industry restructuring in Oklahoma
and is no longer required to satisfy SPP reliability criteria. Until these
conditions are met, the Combined Company will sell 300 MW hours of energy per
hour in a system power sale. The divestiture process for the ERCOT capacity will
begin after the completion of the Merger, unless the Commission determines that
a sale within two years of the Merger will cause the pooling-of-interests
accounting treatment to be unavailable. The proposed sales and subsequent
divestitures are, therefore, specifically structured to meet any concerns that
the increases in market concentration in the SPP and ERCOT markets, without
correction, could have anti-competitive effects on those markets.

       In interpreting the estimated market shares and HHIs, it is important to
recognize that non-firm energy markets have a number of characteristics that
make the exercise of market power, either jointly or unilaterally, extremely
unlikely. In particular, the numerous ways energy transactions can be packaged,
the diversity of the participants in an evolving and increasingly competitive
market, and the fact that buyers are also sellers at various times will make it
exceedingly difficult for the Combined Company to exercise market power through
coordinated behavior.

       As a further mitigation measure, Applicants agreed to waive the Combined
Company's priority with respect to its use of the HVDC ties. As noted in Item
I.B. above, the waiver applies to unplanned (i.e., non-firm) transactions in
ERCOT and non-firm transactions in SPP.

       In sum, it is clear that the Merger will have little or no effect on
competition in the relevant product markets.

                 (y) Vertical Markets

       The Merger raises no vertical concerns. AEP and CSW are not transmission
competitors and each operates under FERC Order No. 888 OATTs. AEP and CSW have
filed a joint Order No. 888 compliance tariff applicable to the Combined System
to be made effective as of the Merger closing date. Hence, Applicants are not in
a position to favor each other in operating their transmission systems.

       As part of the FERC Stipulation and settlements with the staffs of
various state commissions, AEP and CSW each have committed to join an ISO or
RTO, thus eliminating any remaining concerns regarding the transmission
facilities' impact on competition. Through the ISO or RTO, the transmission
facilities will be operated for the benefit of the system users in a competitive
and non-discriminatory manner. In this regard, on June 3, 1999, AEP joined with
four other utilities in filing the Alliance RTO Application, which is currently
pending at FERC. CSW is participating in the ERCOT independent regional
transmission plan for the portion of its system that is within ERCOT and is
participating in discussions with other interested parties about the formation
of an RTO that would include utility systems in the SPP. As part of the
settlement with the staff of the Texas Commission, Applicants agreed that they
would obtain the Texas Commission's prior approval before withdrawing from
either ERCOT or the SPP.

       The Merger raises no vertical issues relating to ownership or control of
scarce generating capacity. There are a number of projects under development and
construction in Texas which



                                                                              49
<PAGE>   50

will be capable of selling into ERCOT and/or the SPP, including an 800 MW
merchant plant located in Grimes County; a 350 MW merchant plant located in
Uvalde County; a 300-400 MW gas-fired cogeneration facility located at Reynolds
Metals' Sherwin alumina production plant near Corpus Christi; a 1,100 MW
gas-fired, combined cycle plant whose output will be sold to Texas Utilities for
two years; a 1,000 MW gas-fired combined cycle facility located in Edinburg,
Texas; a 700 MW merchant plant is planned for Magic Valley Electric Cooperative;
a 510 MW addition is planned for a cogeneration facility located in Pasadena,
Texas; a 500 MW gas-fired combined cycle facility located in Hidalgo County,
Texas.(9) By utilizing the Combined Company's OATT, customers within the
Combined Company's service territory will be able to access numerous suppliers
that independently have constructed substantial generating capacity in the past
and that have located both within and outside the service territory. In the
longer term, with the introduction of retail competition, it is expected that
retail customers will have access to energy service providers with different
generation sources and mixes.

       In addition, Applicants submitted to the FERC testimony by J. Stephen
Henderson demonstrating that, irrespective of the existence of an ISO or RTO,
the Merger will not create any ability or incentive for the Combined Company to
(1) use AEP's transmission system to limit competition in relevant markets into
which CSW sells electricity, or (2) use CSW's transmission system to limit
competition in relevant markets into which AEP sells electricity. A copy of Mr.
Henderson's testimony is filed as an exhibit to Exhibit D-1.2 and is
incorporated by reference. AEP and CSW also presented testimony by Raymond
Maliszewski explaining, among other things, that the configuration of the AEP
System does not permit AEP to affect adversely load flows on third party systems
by departing from economic dispatch of the AEP System. A copy of Mr.
Maliszewski's testimony is filed herewith as Exhibit D-1.2.

       In sum, Dr. Hieronymus' testimony demonstrates that taking into account
the Combined Company's mitigation measures, the Merger presents no competitive
problems. Thus, the Merger can be expected to obtain required approval and
clearance from the FERC. See Madison Gas & Electric (the Commission is entitled
to defer to FERC's expertise in evaluating the competitive aspects of a merger).
To the extent the Commission finds that there is any concentration of control
resulting from the Merger, Applicants believe any such concentration of control
is far outweighed by the benefits accruing to the public, investors and
consumers from the Merger, as more fully discussed in Item 3.B.2 below. Thus,
the Merger will not "tend toward . . . the concentration of control" of public
utility companies, of a kind or to an extent detrimental to the public interest
or the interests of investors or customers within the meaning of Section
10(b)(1).

       2. Section 10(b)(2)

       Section 10(b)(2) of the 1935 Act requires the Commission to approve the
Merger unless it finds that the consideration, including all fees, commissions
and other remuneration, is unreasonable or does not bear a fair relation to the
sums invested in, or the earning capacity of the utility assets underlying the
securities to be acquired.

       (9) Power Generation Markets Quarterly, First Quarter 1999.


                                                                              50

       a. Reasonableness of Consideration

       Section 10(b)(2) "does not demand a mathematical equivalence of values
for the terms of the exchange." Entergy, supra. Prices arrived at through arm's
length negotiations are particularly persuasive evidence that the Section
10(b)(2) requirement is met. See, e.g., Northeast I, supra, (citing Ohio Power,
HCAR No. 16753 (June 8, 1970)). Moreover, the assistance of independent
consultants in setting consideration is deemed to be evidence that the
requirement is met. See, e.g., Northeast I, supra (citing Southern Co., HCAR No.
24579 (Feb. 12, 1988)). The Commission also "independently analyze[s] the
financial and operating performances of [the combining entities]" with respect
to such factors as relative market values and dividends per share. Centerior,
supra. Finally, the Commission considers whether the shareholders have approved
the acquisition. Entergy, supra.

       Under the standards applied by the Commission in previous utility
mergers, the consideration to be paid by AEP in the Merger is reasonable and
bears a fair relation to the earning capacity of the utility assets underlying
the CSW Common Stock to be acquired, in compliance with Section 10(b)(2). Based
on the Exchange Ratio set forth in the Merger Agreement, the consideration
offered by AEP will be AEP Common Stock which had a market value on December 19,
1997, the last trading day before the Merger was announced, of approximately
$6.6 billion, or approximately $31.20 per share of CSW Common Stock, which was
approximately 20% above the closing price of CSW Common Stock on December 19,
1997. Applicants' belief that the consideration is fair and reasonable is based
on the following reasons, each of which is discussed in detail below:

       -      Arm's length negotiations between AEP and CSW conducted in a
              competitive context resulted in the proposed Exchange Ratio;

       -      An opinion from AEP's financial adviser, Salomon, states that the
              consideration to be paid by AEP with respect to the Merger is
              fair, from a financial point of view, to AEP;

       -      An opinion from CSW's financial adviser, Morgan Stanley, states
              that the consideration to be received by CSW's shareholders with
              respect to the Merger is fair, from a financial point of view, to
              CSW's shareholders;

       -      Valuation analysis demonstrates the fairness of consideration as
              evidenced by the comparative market prices of, and dividends paid
              on, the AEP and CSW Common Stock;

       -      The Applicants' shareholders approved the shareholder actions
              necessary to effect the Merger; and

       -      The inclusion of required closing conditions in the Merger
              Agreement serves to assure that the Merger will be consummated on
              terms that are fair to Applicants and their shareholders.

              (i) Competitive Negotiations



                                                                              51
<PAGE>   52

       The chief executive officers of AEP and CSW had informal discussions on
several occasions from January 1997 to March 1997 regarding a merger of the
companies. With CSW's stock price depressed in late April 1997 as a result, in
the opinion of CSW management, of adverse action by the Texas Commission, CSW
management terminated discussions with AEP.

       From May through September 1997, CSW management continued to explore a
variety of strategic alternatives. As part of this analysis, CSW management, in
consultation with its advisers, developed a list of screening criteria for use
in analyzing potential merger partners. CSW also considered other strategic
alternatives which could be pursued without a business combination. At a meeting
of the CSW Board of Directors on September 27, 1997, management recommended to
the CSW Board of Directors that CSW seek a merger that could enhance CSW's
ability to implement its long-term vision. The CSW Board of Directors
unanimously authorized CSW management to pursue its search for an appropriate
merger partner while continuing to evaluate CSW's stand-alone options.

       In September 1997, the chief executive officers of AEP and CSW resumed
their discussions regarding a stock-for-stock merger. During the ensuing months,
CSW's management also held preliminary discussions, and exchanged non-public
information, with three other electric utilities regarding a possible business
combination and continued to evaluate other stand-alone alternatives. CSW
management met with the CSW Board of Directors and a committee of the CSW Board
of Directors on many occasions during October-December 1997 to update the
directors and receive direction on the course of their discussions.

       On November 24, 1997, CSW management and CSW's advisers met with a
committee of the CSW Board of Directors to discuss the progress of the strategic
alternative evaluation process. The committee authorized CSW management to send
to four strategic merger candidates a letter requesting each to advise CSW as to
whether, and on what terms, it was interested in pursuing a strategic
combination with CSW. On December 11, 1997, CSW received affirmative responses
to the request letters from AEP and two of the three other companies.

       On December 12, 1997, CSW management and advisers met with a committee of
the CSW Board of Directors to discuss the responses and the status of the
strategic merger candidate evaluation process. After analyzing the responses and
CSW's other stand-alone alternatives, the committee determined that AEP appeared
to be the best strategic merger partner for CSW and that a merger with AEP on
the right terms would be more likely to restore and enhance long-term
stockholder value than any of the other merger or stand-alone strategic
alternatives.

       Following negotiations between the chief executive officers of each
company, CSW and AEP agreed to proceed with merger negotiations on the basis of
a proposed exchange ratio of 0.60 shares of AEP Common Stock for each share of
CSW Common Stock. The Board of Directors of both companies approved the Merger
Agreement in meetings on December 21, 1997, and the Merger Agreement was signed
that afternoon.

       The Exchange Ratio was agreed to by the Applicants after extensive
deliberations between the two companies involving senior management personnel
assisted by financial and legal advisers skilled in mergers and acquisitions
transactions. Moreover, the negotiations were carried out in a competitive
context with other companies.



                                                                              52

       For further information regarding the background of the proposed Merger
between AEP and CSW, reference is made to the Joint Proxy Statement and
Prospectus filed as Exhibit C-2 and incorporated herein by reference.

                 (ii) Fairness Opinions

       As discussed above, the Boards of Directors of AEP and CSW approved the
Merger Agreement and the transactions contemplated thereby. Prior to such
approvals, the Boards received opinions from AEP's and CSW's respective
financial advisers as to the fairness of the proposed consideration. AEP's Board
of Directors received a written opinion from Salomon that, based upon specified
procedures and assumptions, the consideration to be paid by AEP with respect to
the proposed Merger is fair, from a financial point of view, to AEP. CSW's Board
of Directors received a written opinion from Morgan Stanley that the proposed
consideration is fair, from a financial point of view, to the shareholders of
CSW. No limitations were imposed by the AEP Board or the CSW Board upon Salomon
or Morgan Stanley, respectively, with respect to the investigations made or
procedures followed by their respective financial advisers.

       In arriving at their respective opinions, Salomon and Morgan Stanley
reviewed (i) the terms of the Merger Agreement; (ii) certain publicly available
business and financial information relating to AEP and CSW; (iii) certain other
internal information concerning AEP and CSW, including financial projections
provided to them by AEP and CSW; (iv) certain publicly available information
concerning the trading of, and the trading market for AEP's and CSW's Common
Stock; (v) certain publicly available information with respect to other
companies they believed to be comparable to AEP and CSW and the trading markets
for such other companies' securities; and (vi) certain publicly available
information concerning the nature and terms of other transactions they
considered relevant to their inquiry. They also met with officers and employees
of AEP and CSW to discuss the foregoing as well as other matters relevant to the
Merger. Copies of the fairness opinions are filed as Annexes II and III to
Exhibit C-2 and are incorporated by reference.

       Salomon's fairness opinion was based on eight valuation analyses relating
to, respectively, Discounted Cash Flow Analysis-CSW; Comparable Company
Analysis-CSW; Analysis of Selected Utility Company Mergers and Acquisitions;
Discounted Cash Flow Analysis-AEP; Comparable Company Analysis-AEP; Historical
Trading Ratios Analysis; Contribution Analysis; and Pro Forma Analysis of the
Merger. These analyses supported the fairness of the proposed consideration,
from a financial perspective, to be paid by AEP and are summarized below:

       Discounted Cash Flow Analysis-CSW. This analysis was based on certain
       operating and financial assumptions for CSW in years 1997 to 2006
       provided by CSW and adjusted by the management of AEP. From this
       analysis, Salomon derived a range of the implied equity value per share
       of CSW Common Stock of approximately $25 to $29. In addition, Salomon
       derived a per share present value of the expected Merger savings of $5.
       Thus, Salomon derived a reference range for the implied value per share
       of CSW Common Stock, including savings, of approximately $30 to $34.



                                                                              53
<PAGE>   54

       Comparable Company Analysis-CSW. Salomon reviewed certain publicly
       available financial, operating, and stock market information for CSW and
       five other publicly-traded utility companies Salomon considered
       comparable to CSW. Salomon derived the implied value of the CSW shares on
       (1) a stand-alone basis ($21 to $25 per share); (2) with the Merger
       savings ($26 to $30 per share); and (3) including a 30% control premium,
       but no Merger savings ($27.50 to $32.50 per share).

       Analysis of Selected Utility Company Mergers and Acquisitions. Salomon
       reviewed a set of completed and proposed utility mergers announced since
       August 1996. Salomon calculated multiples based on the offer price for
       each target company to such company's respective pre-announcement market
       price, book value, earnings and cash flow per share. From this analysis,
       Salomon derived a reference range for the implied equity value per CSW
       share of $27 to $35. Discounted Cash Flow Analysis-AEP. This analysis was
       based on certain operating and financial assumptions for AEP in years
       1997 to 2006 provided by AEP. From this analysis, Salomon derived a range
       of the implied equity value per share of AEP Common Stock of
       approximately $42 to $49. Comparable Company Analysis-AEP. Salomon
       reviewed certain publicly available financial, operating, and stock
       market information for AEP and five other publicly-traded utility
       companies Salomon considered comparable to AEP. Salomon derived a range
       of the implied equity value per share of AEP Common Stock of
       approximately $44 to $52.

       Historical Trading Ratios Analysis. Salomon also reviewed the daily
       closing prices of CSW Common Stock and AEP Common Stock during the period
       from December 15, 1992 through December 15, 1997 and the historical
       trading ratios over such period. During that period the average
       historical trading ratio was 0.70. The ratio on December 15, 1997 was
       0.52. Contribution Analysis. Salomon reviewed the relative contributions
       of each of AEP and CSW to estimated net income and other indicators of
       the Combined Company for each of the years 1997 to 2006. This analysis
       showed that CSW is expected to contribute a percentage of the Combined
       Company's net income ranging from approximately 34% to 40% in 1997 to
       2003 before leveling off at 39% in the years 2004 to 2006. CSW
       stockholders would own approximately 40% of the outstanding shares of the
       Company based on the Exchange Ratio.

       Pro Forma Analysis of the Merger. Salomon also analyzed certain pro forma
       effects resulting from the proposed combination for the years 2000
       through 2006. This analysis was based on financial and operating
       assumptions for AEP and CSW, as provided to Salomon by AEP, and assumed
       the realization of the cost savings projected by AEP management to result
       from the Merger. Based on such analysis, Salomon concluded that the
       Merger would be somewhat dilutive to AEP shareholders for the years
       2000-2002 and somewhat accretive for the remaining years of the forecast.
       Salomon noted that the transaction would generally produce earnings per
       share accretion of 10% or more each year for CSW shareholders, but would
       result in a lower dividend per original CSW share of more than 10%
       through 2003, the reduction continuing to decline thereafter.

                 (iii) Comparative market prices of and dividends paid on common
          stock.



                                                                              54
<PAGE>   55

       Market prices at which securities are traded have always been strong
indicators as to values. As shown below, most quarterly price data for CSW
Common Stock and AEP Common Stock, high and low, for the years 1996 and 1997
provide support for the calculation of the Exchange Ratio.

</TABLE>

                 (iv) Shareholder Approval

       In addition, the holders of AEP Common Stock and the holders of CSW
Common Stock overwhelmingly approved the shareholder actions necessary to effect
the Merger. At the Annual Meeting of Shareholders of AEP held on May 27, 1998,
holders of approximately (i) 71% of all outstanding AEP Common Stock approved an
amendment to the Restated Certificate of Incorporation of AEP increasing the
number of authorized shares of AEP Common Stock, and (ii) 72% of all outstanding
AEP Common Stock approved the issuance of the AEP Common Stock, each necessary
to effect the Merger. Holders of approximately 82% of all outstanding CSW Common
Stock approved the Merger at the Annual Meeting of Stockholders of CSW held on
May 28, 1998.

                 (v) Merger Agreement

       Finally, the Merger Agreement contains a number of closing conditions
that help ensure the continued reasonableness of the consideration. Under
Section 8.1(g), it is a condition precedent to closing, applicable to both AEP
and CSW, that "there shall not have occurred and remain in effect a Divestiture
Event with respect to [either company]."(10) Pursuant to Sections 8.2 and 8.3,
AEP and CSW are each required to affirm that all representations made with
respect to the Merger Agreement are true and correct as of the date of closing,
including the representation that no Material Adverse Effect(11) shall have
occurred and that there shall exist no fact or

- -------------------------

       (10) "Divestiture Event" means "any Law, Regulation or Order adopted or
issued by a Governmental Authority that requires the divestiture of a
substantial portion of the generating assets of . . ." CSW or AEP.

       (11) "Material Adverse Effect" means "any change or effect that is
material and adverse to the business, condition (financial or otherwise) or
results of operations or prospects of a specified Person and


                                                                              55
<PAGE>   56

circumstance which may reasonably be expected to give rise to a Material Adverse
Effect. Other closing conditions ensure that the Merger will not be consummated
in the event of onerous or burdensome regulatory orders or conditions.

b.     Reasonableness of Fees

       The various categories of fees, commissions and expenses in connection
with the transaction and regulatory processing costs for the Merger are set
forth in Item 2 to this Application-Declaration. Applicants together expect to
incur total transaction and regulatory processing costs of approximately $53
million, including financial advisory fees of approximately $31 million.

       Applicants believe that these estimated fees and expenses bear a fair
relation to the value of CSW and the savings to be achieved by the Merger and
are fair and reasonable in light of the size and complexity of the Merger.
Northeast Utilities, HCAR No. 25548 (June 3, 1992), modified on other grounds,
HCAR No. 25550 (June 4, 1992) [hereinafter "Northeast II"] (Commission considers
whether fees and expenses bear a fair relation to the value of the company to be
acquired and the savings to be achieved by the acquisition). Based on the price
of AEP Common Stock on December 19, 1997, the transaction would be valued at
$6.6 billion. As discussed in Item 3.B.2 below, net nonproduction savings of
nearly $2 billion and net fuel-related savings of approximately $98 million are
projected over the first ten years after the Merger.

       Moreover, the estimated overall fees are reasonable compared to the
overall fees approved by the Commission in other merger transactions. The total
fees of $53 million to be incurred by Applicants represent approximately 0.8% of
the value of consideration to be paid by AEP, based on the price of AEP Common
Stock on December 19, 1997. The Commission has approved fees, commissions and
expenses of $46.5 million in connection with the acquisition of PSNH by
Northeast, representing approximately 2% of the value of the assets to be
acquired (Northeast I; Northeast II); $47.12 million in connection with the
reorganization of Cincinnati Gas and Electric and PSI Resources as subsidiaries
of CINergy (CINergy Corp., HCAR No. 26146 (Oct. 21, 1994) [hereinafter
"CINergy"]) and $38 million in fees, commissions and expenses in connection with
Entergy's acquisition of Gulf States Utilities Company, representing
approximately 1.7% of the value of the consideration paid to Gulf States'
shareholders (Entergy, supra).

       The investment banking fees of approximately $31 million to be incurred
by Applicants represent approximately 0.47% of the value of consideration to be
paid by AEP, based on the price of AEP Common Stock on December 19, 1997. These
fees incurred by Applicants resulted from a marketplace in which investment
banking firms actively compete with each other to act as financial advisers to
merger participants. The Commission has previously approved financial advisory
fees of approximately $10.6 million, representing approximately 0.46% of the
value of the assets to be acquired (Northeast I, supra and Northeast II, supra),
financial advisory fees

approximately 0.36% of the value of the consideration paid to Gulf States'
shareholders (Entergy, supra and Amendment No. 24 to Entergy Form U-1 (Nov. 18,
1993)).

       As indicated in Item 2 above, the fees and expenses which are not yet
finalized will be filed by amendment when they become available.

       For all of the above reasons, the consideration and fees to be paid are
fair and reasonable in compliance with Section 10(b)(2).

       3. Section 10(b)(3)

       Section 10(b)(3) of the 1935 Act requires the Commission to approve a
proposed acquisition unless the acquisition would unduly complicate the capital
structure of the holding company system, or would be detrimental to the public
interest, the interest of investors or consumers or the proper functioning of
such holding company system.

       a. Capital Structure

       The Commission has found that an acquisition does not unduly complicate
the capital structure of the holding company system where the effect of a
proposed acquisition on the acquirer's capital structure is negligible and the
debt to equity ratio due to the acquisition is well within "the 65/30%
debt/common equity ratio generally prescribed by the Commission." Entergy, supra
(citing Northeast I). The Commission has approved common equity to total
capitalization ratios as low as 27.6%. See Northeast I, supra.

       In this regard, the proposed combination of AEP and CSW will not unduly
complicate the capital structure of the Combined System. The only changes to the
capital structure of AEP will be the acquisition by AEP of CSW Common Stock and
the addition of the capital structure of CSW to AEP's capital structure. CSW and
its subsidiaries have publicly held debt and have publicly held preferred stock
or preferred trust securities, and all CSW Common Stock will be held by AEP and
incorporated within AEP's consolidated financial statements. At December 31,
1997, the respective capital structures of AEP and CSW were as follows:

       If the Merger had been consummated on December 31, 1997, the pro forma
consolidated capital structure of the Combined Company as of such date
(according to generally accepted



                                                                              57

accounting principles, assuming that the Merger is treated as a
"pooling-of-interests" under Accounting Principles Board Opinion No. 16) would
have been as follows:

<TABLE>

</TABLE>

(a)    Includes $53 million of transactions and regulatory processing costs.

       As can be seen from the above tables, the debt to equity ratio is not
altered to any considerable degree by the Merger. The Combined Company's pro
forma consolidated common equity to total capitalization ratio of 44.8% is
substantially higher than Northeast Utilities' recently approved 27.6% common
equity position and comfortably exceeds the "traditionally acceptable 30%
level." Northeast I, supra.

       Finally, the common stock that AEP proposes to issue in the Merger has
the same par value, same rights (including voting rights) and preference as to
dividends and distributions as the AEP Common Stock presently outstanding. All
of the issued and outstanding CSW Common Stock will be owned by AEP as a result
of the Merger. As such, there will be no publicly held minority common stock
interest in CSW following the Merger. Thus, the Merger does not complicate the
capital structure of AEP.

              b. Public Interest, Interest of Investors and Consumers, and
       Proper Functioning of Holding Company System

       Section 10(b)(3) also requires the Commission to determine whether the
proposed Merger will be detrimental to the public interest, the interest of
investors or consumers or the proper functioning of the Combined System.

       As discussed in greater detail in Item 3.B.2 below, the Merger will
enable the Combined Company to operate more efficiently and economically than
either AEP or CSW could operate independently of the Merger. The Merger will
result in substantial, otherwise unavailable, benefits to the public and to
consumers and investors of both companies -- specifically, savings through labor
cost savings, facilities consolidation, corporate and administrative programs,
non-fuel purchasing economies, and efficiencies from the combined utility
operations. These savings will be passed on to shareholders and consumers. The
shareholders, whose interests are protected by the disclosure requirements of
the Securities Act of 1933 and the Securities and Exchange Act of 1934, have
overwhelmingly approved the shareholder actions necessary to effect the Merger.
See Southern, supra (stating that "[c]oncerns with respect to investors have
been largely addressed by developments in the federal securities laws and in the
securities markets themselves.") The interests of consumers are protected by
both state and federal regulation.



                                                                              58
<PAGE>   59

       Simply stated, the Merger will create an entity that will be poised to
respond effectively to the fundamental changes that have taken and will continue
to take place in the markets for electric power as such markets are being
deregulated and restructured and will create an entity prepared to compete
effectively for consumer's business. As such, consumers, investors, and the
public will be the ultimate beneficiaries of the Merger.

       In sum, because the Merger does not add any complexity to AEP's capital
structure and is in the public interest and the interests of investors and
consumers, the requirements of Section 10(b)(3) are met.

       B. Section 10(c)

       Section 10(c) of the 1935 Act establishes additional standards for
approval of the Merger. Under Section 10(c), the Commission cannot approve:

       (1) an acquisition of securities or utility assets, or of any other
interest, which is unlawful under the provisions of Section 8 or is detrimental
to the carrying out of the provisions of Section 11; or

       (2) the acquisition of securities or utility assets of a public utility
or holding company unless the Commission finds that such acquisition will serve
the public interest by tending towards the economical and efficient development
of an integrated public utility system.

          1. Section 10(c)(1)

       Section 10(c)(1) requires that the proposed acquisition be lawful under
the provisions of Section 8 of the 1935 Act. Section 8 prohibits an acquisition
by a registered holding company of an interest in an electric and gas utility
serving substantially the same area without the express approval of the state
commission when that state's law prohibits or requires approval of the
acquisition. Because neither CSW nor AEP has any direct or indirect interest in
any gas utility company, this section is not applicable to the Merger.

       Section 10(c)(1) also requires that the Merger not be detrimental to the
carrying out of the provisions of Section 11. Section 11(b)(1) generally
requires a registered holding company system to limit its operations "to a
single integrated public-utility system, and to such other businesses as are
reasonably incidental, or economically necessary or appropriate to the
operations of such integrated public-utility system." Section 11(b)(2) directs
the Commission "to ensure that the corporate structure or continued existence of
any company in the holding-company system does not unduly or unnecessarily
complicate the structure, or unfairly or inequitably distribute voting power
among security holders, of such holding-company system." The following analysis
demonstrates that the Merger meets the standards of Section 11.

       a. Section 11(b)(1) (Single integrated public utility system)

       The Commission has found that the system of each of the Applicants is a
single integrated electric utility system. See AEP, supra (finding that AEP is a
single integrated system); Central and South West Corp., HCAR No. 22439 (April
1, 1982) (terminating a Section 11(b)(1) hearing and upholding a 1945
determination by the Commission that CSW comprises



                                                                              59
<PAGE>   60

one integrated public utility system). The following analysis supports a
determination by the Commission that the Merger of these two utility systems
will result in a single integrated electric utility system under Section
11(b)(1).

       Section 2(a)(29)(A) of the 1935 Act defines an integrated public utility
system, as applied to an electric utility system, as:

       a system consisting of one or more units of generating plants and/or
       transmission lines and/or distribution facilities, whose utility assets,
       whether owned by one or more electric utility companies, are physically
       interconnected or capable of physical interconnection and which under
       normal conditions may be economically operated as a single interconnected
       and coordinated system confined in its operations to a single area or
       region, in one or more States, not so large as to impair (considering the
       state of the art and the area or region affected) the advantages of
       localized management, efficient operation, and the effectiveness of
       regulation.

       Under this definition, the Commission has established four standards that
must be met before the Commission will find that an integrated public utility
system will result from a proposed merger of two separate systems:

       (i)    the utility assets of the systems must be physically
              interconnected or capable of physical interconnection;

       (ii)   the utility assets, under normal conditions, must be economically
              operated as a single interconnected and coordinated system;

       (iii)  the system must be confined in its operations to a single area or
              region; and

       (iv)   the system must not be so large as to impair (considering the
              state of the art and the area or region affected) the advantages
              of localized management, efficient operation, and the
              effectiveness of regulation.

See, e.g., Environmental Action, Inc., v. SEC, 895 F.2d 1255, 1263 (9th Cir.
1990) (citing In re Electric Energy Inc., 38 SEC 658, 668 (1958)).(12) As
demonstrated below, the Merger meets each of these standards.

- -------------------------

       (12) Although the integrated utility system requirement has been
interpreted to involve a four-part test, Applicants submit that the requirement
can be fairly interpreted to involve only a three-part test. The plain reading
of the integration requirement suggests the last two tests should be read as one
test. The requirement provides, in pertinent part, that the "system [be]
confined in its operations to a single area or region, in one or more States,
not so large as to impair (considering the state of the art and the area or
region affected) the advantages of localized management, efficient operation,
and the effectiveness of regulation." There is no "and" inserted between "single
area or region" and "not so large as to impair" leading to the conclusion that
there are two distinct tests which the "system" must meet. Rather, the sentence
construction leads to the conclusion that it is the "single area or region"
which must not be so large as to result in the specified impairments. In any
event, the proposed Merger meets either the three-part test, as set forth in the
statute, or the four-part test.



                                                                              60
<PAGE>   61

       The Commission must interpret the statutory integration standards "to
meet the problems and eliminate the evils enumerated in [the 1935 Act.]" Section
1(c). In so interpreting the integration standards, the Commission must balance
the 1935 Act's various objectives. See, e.g., Union Electric, supra (the
Commission noted that in the past it had "exercise[d] [its] discretion so as to
allow the expeditious consummation of plans that would make for financial
simplification even though they fell far short of full compliance with the Act's
integration standards" because "with respect to the enforcement of this complex
multifaceted and far-reaching statute" it had "found it necessary or appropriate
to subordinate some statutory objectives to others."). The various aspects of
the integration standard cannot be considered independently of one another and
the other objectives of the 1935 Act. See, e.g., Middle West Corp., HCAR No.
4846 (Jan. 24, 1944) (the Commission noted that while it was difficult to reach
the conclusion that the systems constituted a single system given the geographic
spread of the properties, the integration test was met due to the "contemplated
savings resulting from closely coordinated operation and joint planning with
respect to the routing of power and the installation of facilities."); Middle
West Corp., HCAR No. 5606 (Feb. 16, 1945) (the Commission found that the
combined system was not too large "in light of demonstrated disadvantages of
lack of coordination."); Sempra Energy, HCAR No. 26971 (Feb. 1, 1999)
[hereinafter "Sempra"], citing North American Co., 18 SEC 459, 463 (1945)(in
connection with evaluating the integration standard for gas utility systems, the
Commission has "read each standard of section 2(a)(29)(B) in connection with the
other provisions of the section"). Where the acquisition will result in
significant economies and efficiencies to the benefit of the public, investors
and consumers, Commission precedent supports a flexible interpretation of the
integration standards to further the very interests that the 1935 Act was meant
to protect.

       The Commission has recognized that the 1935 Act "creates a system of
pervasive and continuing economic regulation that must in some measure at least
be refashioned from time to time to keep pace with changing economic and
regulatory climates." Southern, supra (quoting Union Electric, supra). The
Commission interprets the 1935 Act and its integration standards "in light of []
changed and changing circumstances." Sempra, supra (interpreting the integration
standards of the 1935 Act in light of developments in the gas industry). Accord,
NIPSCO Industries, Inc., HCAR No. 26975 (Feb. 10, 1999) [hereinafter "NIPSCO"].
The Commission has cited with favor U.S. Supreme Court and Circuit Court of
Appeals cases(13) that recognized the need of an agency to "adapt [its] rules
and policies to the demands of changing circumstances"(14) and to "treat
experience not as a jailer but as a teacher."(15)

       As the definition of an integrated public utility system suggests, and as
the Commission has previously observed, Section 11 is not intended to impose
"rigid concepts" but rather creates a "flexible" standard designed "to
accommodate changes in the electric utility industry." UNITIL Corp., HCAR No.
25524 (April 24, 1992) [hereinafter "Unitil"]; see also Yankee Atomic Elec.

Co., HCAR No. 13048 (Nov. 25, 1955) [hereinafter "Yankee Atomic"] ("We think it
is clear from the language of Section 2(a)(29)(A), which defines an integrated
public utility system, that Congress did not intend to imposed [sic] rigid
concepts with respect thereto." (citations omitted)). Section 2(a)(29)(A)
expressly directs the Commission to consider the "state of the art" in analyzing
size and to apply "normal conditions" as the standard for determining whether a
system may be economically operated as a single coordinated system. The
Commission is not constrained by its past decisions interpreting the integration
standards based on a different "state of the art." See AEP, supra (noting that
the state of the art -- technological advances in generation and transmission,
unavailable thirty years prior -- served to distinguish a prior case and
justified "large systems spanning several states.")

       The concept of what constitutes an integrated public utility system has
evolved in light of the dramatic changes in the law, technology and structure of
the industry since the passage of the 1935 Act over 60 years ago. In recent
years, the "state of the art" has changed enormously. As the Energy Information
Administration of the Department of Energy aptly noted, "The era of competition
in the electric industry is upon us." Energy Information Administration,
Department of Energy, The Changing Structure of the Electric Power Industry: An
Update (last modified May 30, 1997) <http://www.eia.doe.gov/cneaf/electricity/
chg_str/intro.html>.

       The initial groundwork for competition was laid by the passage of PURPA
in 1978, which opened wholesale markets to certain non-utility producers. PURPA
created a new class of non-utility generators, QFs, from which utilities were
required to buy power. The passage of the Energy Act in 1992 marked another
significant step towards the deregulation of the electric power industry. The
Energy Act was designed, among other things, to foster competition in the
wholesale market through (a) amendments to the 1935 Act that facilitated and
encouraged the ownership and operation of generating facilities by EWGs (which
may include IPPs as well as affiliates of electric utilities) and (b) amendments
to the FPA, authorizing the FERC under certain conditions to order utilities
that own transmission facilities to provide wholesale transmission services for
other utilities and entities generating electric power. FERC Order Nos. 888 and
889, issued in April 1996, taken together provide that public utilities must
file OATTs permitting open access to transmission and must functionally or
actually unbundle their transmission services, by requiring them to use their
own transmission tariffs in making off-system and third-party sales.

       In response to deregulation in the wholesale market for electricity, many
state legislatures and regulatory commissions either have adopted or currently
are considering the adoption of "retail customer choice" provisions. In general
terms, these initiatives require the electric utility to transmit electric power
over its transmission and distribution system to a retail customer in its
service territory. A requirement to transmit directly to retail customers
permits retail electric customers to purchase electric power, at the election of
such customers, either from the electric utility in whose service area they
reside or from another electric service provider or directly from an electric
generator source.

       As of the date of this filing, state electric restructuring plans have
been adopted by the state public utility commissions or legislatures in
approximately twenty four states, and all but a few states currently are
studying or taking action aimed at restructuring their electric markets. Of the
states in which the Combined Company will operate, restructuring legislation has
been



                                                                              62
<PAGE>   63

adopted in Oklahoma, Virginia, Arkansas, Texas, and Ohio. Investigations have
been commenced which are expected to lead to restructuring plans in the
remaining states in which the Combined Company will operate.

       In Oklahoma, legislation allowing retail competition was passed in April
1997, and amended in September, 1998. Retail choice is scheduled to commence by
July 1, 2002. Currently, restructuring related studies are being conducted and
are expected to be completed by October, 1999.

       In March 1999, Virginia enacted a new law to restructure the electric
utility industry in that state. Under the restructuring law, a transition to
choice of supplier for retail customers will commence on January 1, 2002 and be
completed, subject to a finding by the Virginia State Corporation Commission
that an effective competitive market exists, by January 1, 2004. Provisions
allowing for an acceleration or limited delay in this schedule are also
contained in the law. Except as provided in the law, the generation of
electricity will not be subject to rate regulation after January 1, 2002.
Additionally, each Virginia electric utility is required by 2001 to join or
establish a regional transmission entity which will manage and control
transmission assets. The Virginia restructuring law also provides an opportunity
for recovery of just and reasonable net stranded costs.

       On April 15, 1999, the Governor of Arkansas signed into law a
comprehensive restructuring bill that calls for retail competition to start as
early as January 1, 2002, but in no event later than June 30, 2003. Under the
measure, utilities may recover transition and net stranded costs and may use
securitization to mitigate stranded costs. Utilities that recover stranded costs
must freeze rates for residential and small commercial customers for three
years, and, for those utilities that do not recover stranded costs, rates must
be frozen for one year. Utilities must functionally unbundle into generation,
transmission, and distribution units by either creating separate divisions,
nonaffiliated companies, separate affiliated companies, or by selling assets to
a third party. The Arkansas Commission can force divestiture of generation
assets to alleviate market power, and it can decide if stockholders should share
stranded cost recovery with ratepayers.

       On June 18, 1999, the Governor of Texas signed legislation enacting
retail competition in Texas. Under the legislation, full retail competition is
scheduled to commence by January 1, 2002. Electric rates are frozen for a three
year period from January 1, 1999 to January 1, 2002 and, thereafter, a 6% rate
reduction will be offered to residential and small commercial consumers. In
addition, no power generation company may own and/or control more than 20% of
the installed generation capacity in ERCOT.

       On July 6, 1999, the governor of Ohio signed a bill that restructured the
electric utility industry in Ohio affecting OPCo and CSPCo. Under the law,
customer choice in electric energy supply is to begin on January 1, 2001, with a
transition period to end by December 31, 2005. The law provides Ohio electric
utilities the opportunity to recover regulatory assets and other potential
stranded costs. The Ohio Commission will address recovery of stranded costs and
other issues based on each utility's transition plan which is to be filed by the
end of 1999.



                                                                              63
<PAGE>   64

       Taken together, these fundamental changes in the legal and regulatory
framework governing the electric utility industry are producing the following
structural changes:

       -      FERC Order No. 888 and the concomitant development of ISOs and
              FERC's recent Notice of Proposed Rulemaking regarding the
              development of RTOs are moving the electric power industry to a
              disaggregation of control over generation and transmission.
              Utilities that retain control of their generation capacity are
              ceding significant control over their transmission capacity, and
              vice-versa. Consequently, the "1935 model" of an integrated public
              utility holding company as one that combines generation and
              transmission is being supplanted by a different model in which the
              two functions are separated.

       -      One goal of the above-described disaggregation is to eliminate
              ownership of transmission facilities as a barrier to entry into
              power markets for those who are ready to compete for customers
              traditionally served by electric utilities. If nondiscriminatory
              access to transmission facilities is guaranteed, distance will be
              significantly reduced as a barrier to competition.

       -      An electricity futures market and electricity spot markets, as
              well as newly formed entities, such as power marketers, brokers,
              ISOs and RTOs, have emerged as new market structures and
              participants. More than 100 marketers have registered with the
              FERC to trade in electric power. See "Restructuring Energy
              Industries: Lessons From Natural Gas," Energy Information
              Administration, Natural Gas Monthly, May 1997.

       One way in which investor-owned utilities are seeking to improve their
position in today's increasingly competitive market is through mergers and
acquisitions. Between 1986 and 1996, thirty-nine electric investor-owned
utilities merged with other utilities in the industry. Energy Information
Administration, Department of Energy, The Restructuring of the Electric Power
Industry: A Capsule of Issues and Events (Feb. 10, 1998). Between 1992 and the
first half of 1998, 48 investor-owned electric utilities have been involved in
the domestic merger and acquisition process. Edison Electric Institute, "Merger
& Acquisitions," EEI Financial Information (August 28, 1998). AEP and CSW are
seeking to merge to further their mutual strategy of adapting to these historic
changes in the electric utility industry.

       Finally, recent years have witnessed technological advances unforeseeable
in 1935. Developments in telecommunications and computer technology, along with
parallel technological breakthroughs in transportation, have dramatically
reduced, if not eliminated, distance as a significant barrier to centralized
management and coordinated operation of any enterprise. It is a truism that
today's "global village" is a much smaller place than the world of 1935.
Developments in the transportation industry have greatly reduced travel times.
And information travels instantly. Computers provide "real time" information to
central management, providing it with comprehensive, timely information and the
capacity to assert central control over diverse operations.

       In 1935, "an electric utility system generally included local generation,
transmission and distribution, [and] little long-distance transmission . . ."
Unitil, supra. Power plants were

relatively small and isolated, and there was no economical way to transmit power
over any great distance. 1995 Report at 1, n. 1 (citation omitted). In today's
world, "improved transmission and monitoring technologies have increased the
feasible geographic bounds for supply choice; a geographic radius of 1,000 miles
or more is currently considered reasonable for choosing among supply options."
Rodney E. Stevenson & David W. Penn, "Discretionary Evolution: Restructuring the
Electric Utility Industry," Land Economics, Vol. 71, No. 3 (August 1, 1995).

       Technological advances have occurred with respect to the "size" of
transmission lines. The building and expansion of the bulk power transmission
networks (345 Kv to 765 Kv lines) throughout the United States has allowed for
the transfer of large amounts of power over great distances. The construction of
such facilities has increasingly made it possible for electric utilities with
service territories over large geographic areas to share resources in providing
more reliable and economic service to their customers. There were less than 100
circuit miles of 345 Kv lines prior to 1950 and less than 100 circuit miles of
500 Kv lines prior to 1960. Electric Power Research Institute, Transmission Line
Reference Book (2d ed., revised, 1987) at 15 [hereinafter "Transmission Line"].
The first 765 Kv lines in the United States were built for AEP and were
energized in 1970. Id. at 14. Transmission lines above 189 Kv have grown from
7,800 circuit miles in 1950 to 151,700 circuit miles in 1995. Edison Electric
Institute, EEI Pocketbook of Electric Utility Industry Statistics (42d ed. 1997)
at 38. The contribution percentage of these lines above 189 Kv as compared to
all transmission lines above 22 Kv has grown from 3.3 % in 1950 to 22.6 % in
1995. Id.

       Technological advances have also occurred with respect to the "type" of
transmission lines. The application of HVDC technology provides the ability to
transmit bulk power over longer distances with less energy loss and normally
with a smaller investment than with alternating current ("AC") transmission
lines. This technology provides an economical way to interconnect separated AC
power grids and enables power transfers to occur between these systems such that
it not only provides for improved economies, but also provides improvements in
reliability. HVDC technology was not commercially applied in the United States
for bulk power transfers until 1970, with the operation of the Pacific Intertie,
Stage 1 USA. Transmission Line at 17. From 1968 to 1981, there were 11,326 MWs
of HVDC capacity added in North America. Id. HVDC capacity has continued to be
added in different areas of the United States since 1981. In fact, the CSW
System constructed and placed in service a 220 MW HVDC interconnection between
the SPP and ERCOT in December 1984. In August 1995, another HVDC interconnection
rated at 600 MW owned by CSW and several other electric utility partners was
placed in service between the same two power pools, but at a different location.

       The application of phase shifting transformers, series compensation, and
flexible alternating current transmission system ("FACTS") technology has also
provided the ability to improve and control the transfer of power and energy
across expansive transmission networks. Their use historically has been more
selective because of the operational problems that accompany their day- to-day
use. However, over the years with improvements in technology and operating
experience, their application is becoming more common. New flexible alternating
FACTS technology can increase the capacity of existing transmission lines by
approximately 20 to 40 percent. Electricity: Innovation and Competition, Hearing

utilities operate their bulk power networks closer to their inherent thermal
limits, while maintaining and/or improving network security and reliability."
Id.

       Advances in telecommunications and computer technology have improved the
ability to economically dispatch power systems and control power flow across
such systems. Improvements in telecommunication technology and the growth in
coverage area of telecommunications systems have allowed for the quick and
reliable transfer of data necessary to control and dispatch from a single
location generation that can be scattered over large geographic areas. During
the last 10 to 15 years, the expansion of microwave and fiber optic networks has
provided utilities the ability to transfer information at much greater speeds,
with improved quality, and greater reliability. Prior to the 1970s, data was
transferred at baud rates as low as 75 baud (bit per second), sometimes being
transmitted over the power lines themselves. Today, data transferred from the
field to central control centers is at a minimum 1200-baud rate to accomplish 2
second scan rates. Larger data transfers between control centers are normally
accomplished at transfer rates from 56 kbaud to 224 kbaud.

       Computer technology necessary to economically dispatch power systems and
to control power flow across the bulk power transmission system has advanced
significantly since 1935, especially within the last ten years. The improvements
provided by fast and reliable telecommunication network allow for the control
and economic dispatch of power systems that extend over large geographic areas,
providing system operators an almost real time ability to monitor and control
the power system. Current control systems include software programs that can
help the operator analyze the real time operation of the power system and look
for potential problems before they occur. These complex programs have the
ability to suggest corrective measures and, in some cases, implement responses
without system operator participation. Such programs provide utilities greater
ability to obtain more capability out of their existing electric system, improve
system reliability, and improve economies. See, e.g., discussion of Central
Dispatch Planning and Central Economic Dispatch in Item 1.B.3.a, supra.

       In addition, significant improvements in transmission and resource
planning have occurred since 1935. There are several software packages available
today that enable the system planner to model the operation of most of the
equipment used on a power system. Studies can be performed that not only
evaluate power transfer capabilities, but also allow the system planner to add
different types of equipment to determine their impact on increasing power
transfer capabilities. Development of such software has enabled the system
planner to determine what equipment functions best as well as where and when it
should be installed. Further technological advances can be expected in the
future as "power engineers" explore the potential for computers to optimize the
efficiency and reliability of the North American power network. Leslie Lamarre,
"The Digital Revolution," EPRI Journal, Jan./Feb. 1998.

       The fundamental changes in technology outlined above dramatically alter
the "state of the art" which Congress, more than sixty years ago, directed the
Commission to consider. Such fundamental changes led the Division, in the 1995
Report, to state that it intends to apply a more flexible interpretation of the
integration requirements under the 1935 Act; and the Division recommended that
the Commission "respond realistically to the changes in the utility industry and
interpret more flexibly each piece of the integration equation." 1995 Report at
67. The



                                                                              66
<PAGE>   67

Division further noted that in considering the integration requirements, the
Commission should place more focus on the acquisition's "demonstrated economies
and efficiencies." Id. at 69.

       Each of the four integration standards is discussed below.

                 (i) Interconnection

       The Combined System will be physically interconnected or capable of
interconnection. The required method of interconnection is not defined in the
1935 Act. The Commission has recognized that the interconnection requirement
should be applied flexibly to allow for methods of interconnection beyond simply
a transmission line owned by the merging utilities. In this regard, the
Commission has found (which finding was upheld on appeal) sufficient a
"three-year 'firm contract' to use a transmission line owned by two unrelated
parties." WPL Holdings at 2262-63, aff'd, Madison Gas & Electric; Conectiv Inc.,
66 S.E.C. Docket 1260 (1998) [hereinafter "WPL Holdings"] ("Delmarva and
[Atlantic City Electric] are interconnected through their undivided interests
in, and/or rights to use, the same regional generation facilities and extra-high
voltage transmission facilities, as well as through their contractual rights to
use the transmission facilities of other members of the PJM regional power
pool") [hereinafter Conectiv]; Northeast I, supra (interconnection standard met
where combining entities reached an agreement to obtain service by utilities
with a transmission line interconnecting the two systems); Centerior, supra
(interconnection standard met where merging systems could be interconnected
through a power transmission line, owned by an unaffiliated company, that each
had the right to use).

       The Division has recommended that the Commission "respond realistically
to the changes in the utility industry and interpret more flexibly each piece of
the integration equation," including the physical integration requirement. 1995
Report at 67. The means through which two utilities are physically capable of
sharing power has expanded with changes in the industry. Utility companies can
now share power through power pool arrangements, reliability councils, RTOs, and
ISOs.

       The 1935 Act does not require two merging utilities to demonstrate, at
the time of the merger application, the method through which they will be
interconnected throughout the lifetime of the combined system. Northeast I supra
(Commission approved a merger where the combining utilities only had an absolute
right to use a third party transmission line for 10 years). The statute also
does not require that the merging utilities be interconnected from the outset.
Rather, the merging utilities need only be "capable of interconnection" to meet
the physical interconnection requirement.(16)

- -------------------------

       (16) To meet the Section 11(b)(1) integration standard, the utility
assets of the currently existing system need only be "capable of physical
interconnection" based on the definition found in Section 2(a)(29)(A). In
another recent case, two merging utilities had no contract path but merely an
intention to construct a new transmission tie-line within five years in order to
interconnect their systems. On that basis, the Commission found that the merging
utilities were "capable of being interconnected." New Century Energies Inc., 65
S.E.C. 277, 314-16 (1997) [hereinafter New Century Energies]. By any



                                                                              67
<PAGE>   68
                 As noted in Item 1.B.3 above, AEP and CSW will interconnect
their systems through the 250 MW Contract Path across the Ameren system. Under
Commission precedent, this satisfies the interconnection requirement of Section
2(a)(29)(A). Moreover, the Applicants have the ability through the Ameren OATT
to renew the Contract Path. Thus, the Contract Path provides the Applicants with
the means to meet the interconnection standard under the Act and, at the same
time, preserves flexibility to enter into more favorable arrangements should
they become available during the four-year term of the Ameren contract. As noted
above, the electric industry is in the process of dynamic change; there is
growing pressure on public utilities to restructure and increasing competition
in the marketplace. Applicants believe that within the next four years there may
be transmission interconnection alternatives available as a result of these
changes and that the Commission therefore should find the Contract Path to be
sufficient. Although the precise method of interconnection has not yet been
determined four years into the future, the Applicants commit to continue to meet
the interconnection requirement at that time.

       As noted in Item 1.B.3., Applicants have committed to limit their
reservation of firm transmission service from east to west to 250 MW unless the
FERC authorizes them to go above this limit.(17) See Dr. Hieronymus' testimony
filed as an exhibit to Exhibit D-1.2.

       As discussed above in Item 1.B.3, Applicants' goal ultimately is to
further enhance the interconnection of the Combined System through participation
in a regional RTO (subject to the need of the CSW-ERCOT companies to continue
participation in the ERCOT ISO). Assuming that the Combined Company belongs to a
single RTO, the RTO will have the capability to use the other members'
transmission lines to transmit power within the Combined System. The effect is
the same even if the Combined Company belongs to separate but contiguous RTOs,
provided the RTOs are not permitted to erect economic barriers between them.(18)
In this regard, the Commission has found that the transmission rights associated
with being a member of an ISO help to satisfy the interconnection requirement.
Conectiv, supra.

                 (ii) Single Interconnected and Coordinated System

- --------------------------------------------------------------------------------

reasonable measure, an intention to construct a tie-line is far more tenuous
than an actual physical interconnection, by contract or otherwise.

       (17) Applicants have committed to limit their reservation of firm
transmission service to avoid potential anticompetitive effects as a result of
the Merger, which is an additional consideration under the 1935 Act. In applying
the 1935 Act, the Commission must 'weigh policies [of the 1935 Act] against each
other and against the needs of particular situations.' Union Electric, supra.
The limitations to which the applicants have agreed represent a reconciliation
of the various objectives of the 1935 Act in furtherance of the interests which
the 1935 Act was meant to protect, those of investors, consumers and the public.

       (18) In this regard, the Commission has previously approved a merger
where the merging utilities were in more than one reliability council. See New
Century Energies, supra (approving a merger in which one of the merging utility
systems was located in the southwest corner of the eastern United States
electricity grid and was a member of the Southwest Power Pool, a regional
reliability coordinating organization in the eastern grid, and the other merging
utility system was located in the western United States electrical grid and was
a member of the Western Systems Coordinating Council, a reliability council for
members in the western United States electrical grid).



                                                                              68
<PAGE>   69

       The Combined System will be capable of being economically operated as a
single interconnected and coordinated system, as required by Section
2(a)(29)(A). The Commission has "interpreted this language to refer to the
physical operation of utility assets as a system in which, among other things,
the generation and/or flow of current within the system may be centrally
controlled and allocated as need or economy directs." Conectiv, supra (citing
North American Co., 11 SEC 194, 242 (1942), aff'd, SEC v. North American Co.,
133 F.2d 148 (2d Cir. 1943), aff'd on constitutional issues, 327 U.S. 686
(1946)). Through this standard, Congress "intended that the utility properties
be so connected and operated that there is coordination among all parts, and
that those parts bear an integral operating relationship to one another." Id.
(citing Cities Services Co., 14 SEC 28, 55 (1943)).

       The Commission has considered advances in technology and the particular
operating circumstances in applying this integration standard. Unitil, supra
(citation omitted). For example, in Unitil, the Commission found that
participation in a power pool was sufficient to meet the economic integration
standards even though the "definition [of economic integration] reflects an
assumption that the holding company would coordinate the operations of the
integrated system." Similarly, in approving the acquisition of PSNH by
Northeast, the Commission noted that "the operation of the generating and
transmission facilities of PSNH and the Northeast operating companies is
coordinated and centrally dispatched under the NEPOOL Agreement [a regional
power pool agreement]." Northeast I, supra at n. 85. In Conectiv, supra, the
Commission noted that in addition to coordinated operation through an ISO,
Conectiv would also have a central operating transmission and generation control
center for the essentially local functions of the Conectiv system, thereby
meeting the standard.

       The Combined System will operate as a single interconnected and
coordinated system through the centralized coordination of generation and
transmission. The centralized coordination within the Combined System will be
accomplished under the System Integration Agreement and the System Transmission
Integration Agreement, both of which will take effect upon consummation of the
Merger, as described above in Item 1.B.3. Through Central Dispatch Planning, the
coordination of each generation unit in the Combined System will be scheduled on
a day ahead basis. Central Economic Dispatch will compute at regular intervals
(currently every four seconds) the most economic generation base points as
dictated by current operating conditions and will adjust the dispatch of each
generating unit in the Combined System. Taken together, the software programs
are designed to forecast and economically dispatch all generation resources to
meet the load requirements of the Combined System every four seconds,
twenty-four hours a day. The Applicants' goal ultimately is to further enhance
the coordination of their companies through participation in a regional RTO.

       The RTOs that are evolving under FERC's direction perform similar
planning and reliability functions that regional reliability councils have
performed in the past. Participation in RTOs can enhance the Combined Company's
system reliability in several ways. In the RTO NOPR, as noted above, the FERC
found that an RTO would improve efficiencies in the management of the
transmission grid (RTO NOPR mimeo at 90); would improve grid reliability (RTO
NOPR mimeo at 95); would improve market performance (RTO NOPR mimeo at 98); and
would facilitate lighter governmental regulation (RTO NOPR mimeo at 101). In
addition, RTOs are assuming the functions of administering transmission service
tariffs and performing real time system security and balancing functions that
are related to maintaining reliability and ensuring



                                                                              69
<PAGE>   70

non-discriminatory access to transmission facilities. Thus, AEP's participation
in an RTO is expected to enhance its ability to operate the Combined System in
an efficient and reliable manner.

       Until such time as the Combined Company transfers certain control area
functions related principally to reliability and access to one or more RTOs, all
facets of the centralized coordination of the transmission facilities of the
Combined Company's system will be accomplished through the System Transmission
Integration Agreement. At such time as AEP transfers to the RTO certain control
area operations relating principally to system reliability and access, the
remaining functions of the Combined Company's transmission system will continue
to be coordinated through the System Integration Transmission Agreement.

       In addition thereto, the Combined System will be coordinated in a variety
of ways beyond simply the coordination of the generation and transmission within
the system. AEPSC will be the designated agent under the System Integration
Agreement. AEPSC's major functions will be to coordinate the planning and design
or purchase of new generation facilities, the operation and maintenance of
generating capacity resources, economic dispatch, centralized trading and
marketing activities, acquisition and provision of transmission services needed
for inter-zone power transfers and billing and administration. In addition, the
accounting functions of the Combined System will be prepared and consolidated
through the use of a single enterprise-wide financial system. This financial
system will include a general ledger module, accounts receivable and cash
remittance processing modules, an accounts payable module, a purchasing and
materials management module, owned and leased assets modules as well as a single
integrated timekeeping and payroll system. These systems will enable the
Combined Company to have a single accounting organization which will be managed
by a single team in one or more locations.

       In applying the 1935 Act's integration standard, the Commission looks
beyond simply the coordination of the generation and transmission within the
system to the coordination of other activities. See, e.g., General Public
Utilities Corp., HCAR No. 13116 (Mar. 2, 1956) [hereinafter "GPU"] (integration
is accomplished through power dispatching by a central load dispatcher as well
as through coordination of maintenance and construction requirements); Middle
South Utilities, HCAR No. 11782 (March 20, 1953), petition to reopen denied,
HCAR No. 12978 (Sept. 13, 1955), rev'd sub nom. Louisiana Public Service Comm'n
v. SEC, 235 F.2d 167 (5th Cir. 1956), rev'd, 353 U.S. 368 (1957), reh'g denied,
354 U.S. 928 (1957) (integration is accomplished through an operating committee
which coordinates not only the scheduling of generation and system dispatch, but
also makes and keeps records and necessary reports, coordinates construction
programs and provides for all other interrelated operations involved in the
coordination of generation and transmission); The North American Co., HCAR No.
10320 (Dec. 28, 1950) (economic integration is demonstrated by the exchange of
power, the coordination of future power demand, the sharing of extensive
experience with regard to engineering and other operating problems, and the
furnishing of financial aid to the company being acquired).

       The coordination and integration of the Combined System is expected to be
further achieved through the coordination and integration of information system
networks; procurement



                                                                              70
<PAGE>   71

organizations and organizational structures for Power Generation, Nuclear
Generation, and Energy Delivery and Customer Relations. Each is discussed below:

       -      Analysis completed to date has concluded that there are
              approximately 600 information systems software packages which
              support either AEP or CSW operations. This initial analysis has
              concluded that these packages can be organized under a single,
              integrated information system network with the capability of being
              operated from a single location. The network will be supported by
              a single data center and will have common software tools and a
              single centralized IT development organization. The individual
              integration teams are currently analyzing the various software
              systems being used by each of the companies in order to identify
              the single best system to be utilized to support the Combined
              Company in each area.

       -      AEP and CSW each have created centralized procurement
              organizations which assist the business units in preparing bid
              solicitations, procuring materials and supplies and managing the
              inventory required to support the assets of each business unit.
              The Combined Company expects to utilize a single organizational
              structure to accomplish these activities.

       -      AEP and CSW each have created four substantially equivalent
              business unit management and organizational structures: Power
              Generation, Nuclear Generation, and Energy Delivery and Customer
              Relations. Each of these business units has created a combination
              of central management and engineering groups with regional and
              field organizations designed to provide the services of the
              business unit as efficiently as possible. The integration teams
              are studying how best to integrate these activities. It is
              anticipated that each of the business unit structures recommended
              for the Combined Company will be similar to the existing single,
              integrated organizational structure that is being used in AEP and
              CSW.

       -      AEP and CSW currently utilize a single service company model to
              provide support services, including office, finance, treasury,
              legal, corporate communications and other corporate services. Upon
              the merger of AEPSC and CSWS, these services would be effectively
              provided by combined groups handling office, finance, treasury,
              legal, corporate communications and other corporate services.

       As dictated by the language under Section 2(a)(29)(A) that the
coordinated system be "economically operated," the Commission further analyzes
whether the coordinated operation of the system results in economies and
efficiencies. See, e.g., City of New Orleans v. SEC, 969 F.2d 1163, 1168 (D.C.
Cir. 1992) (Court supported Commission's reading of the term "economically" to
mean "that facilities, in addition to their physical interconnection, be
consolidated so as to take advantage of efficiencies"); WPL Holdings, Inc., HCAR
No. 26856 (Apr. 14, 1998) (discussing this integration standard as it relates to
the requirement under Section 10(c)(2) that the acquisition tend towards the
economic and efficient development of an integrated system and noting that the
applicants introduced substantial evidence concerning the



                                                                              71
<PAGE>   72

efficiencies to be realized by the combined operation of the merging companies'
generation and transmission systems). The Applicants expect to realize
significant economies and efficiencies as a result of the Merger. As described
in Item 3.B.2 below, Applicants estimate the net non-fuel savings from the
Merger to be nearly $2 billion and the net fuel-related savings to be
approximately $98 million over the first ten years following the Merger.

       In short, pursuant to the System Integration Agreement, the Combined
System will be centrally and efficiently planned and dispatched. Pursuant to the
System Transmission Integration Agreement, the operation and management of
transmission within the Combined System will be centrally overseen. Thus, as
with other merger applications approved by the Commission, the Combined System
will be capable of being economically operated as a single interconnected and
coordinated system. The Combined System will be "economically operated" as a
coordinated system as further demonstrated by the variety of means through which
its operations will be coordinated and the efficiencies and economies expected
to be realized by the Merger as described below in Item 3.B.2.

       As required by Section 2(a)(29)(A), the Combined System's operations will
be confined to a "single area or region in one or more States." While the terms
"area" and "region" are not defined in the 1935 Act, it is clear that the
"single area or region" requirement does not mandate that a system's operations
be confined to a small geographic area. The Section specifically provides that a
region can encompass more than one state. As Ganson Purcell, Chairman of the
Securities and Exchange Commission, testified before the Subcommittee of the
House Committee on Interstate and Foreign Commerce in 1946:

       I wish to make it clear that the Act does not require that an integrated
       utility system be broken up, whether or not it crosses State lines, or
       that a holding company necessary to integrate the properties of several
       operating companies be abolished. . . .(19)

He further stated:

       [T]he Commission has not imposed any narrow limit on the concept of what
       is an integrated utility system. Recently, . . . we found that . . . [a]
       system serving 1700 communities in seven states[] was an integrated
       electric utility system. . . .(20)

No absolute size limitation is specified. The terms "area" or "region," by their
nature, are capable of flexible interpretation, which permits the Commission to
respond to the current state of the industry and allows the Commission to give
the terms practical meaning and effect. The

                                                                              72

Commission has found that the single area or region test should be applied
flexibly when doing so does not undercut the policies of the 1935 Act "against
'scatteration' -- the ownership of widely dispersed utility properties which do
not lend themselves to efficient operation and effective state regulation."
NIPSCO, supra (applying single area or region requirement with respect to gas
utility system); accord, Sempra, supra. The 1935 Act itself provides, and the
Commission recognizes, that the question of size must be informed by practical
considerations, including its effect, if any, on the "advantages of localized
management, efficient operation, and the effectiveness of regulation"(21) in
light of "the state of the art and the area or region affected" as discussed in
Item 3.B.1.a.(iv) below.(22)

       In considering size, the Commission has consistently found that utility
systems spanning multiple states satisfy the single area or region requirement
of the 1935 Act. For example, the Entergy system covers portions of four states
(Entergy, supra), the Southern system provides electric service to customers in
portions of four states (Southern Co., HCAR No. 24579 (Feb. 12, 1988)), and the
principal integrated system of NCE covers portions of five states (with all of
its electric operations serving customers in six states) and operates in two
reliability councils (New Century Energies supra (citation omitted)). Other
registered holding companies also operate in multiple states. For example, the
Allegheny Energy, Inc. system provides electricity to customers in parts of five
states (Filings under the Public Utility Holding Company Act of 1935, HCAR No.
26846 (March 20, 1998)). As early as 1945, the Commission found that AEP's
operations in seven states were confined to a single region or area. American
Gas and Electric Co., HCAR No. 6333 (Dec. 26, 1945). In addition, in light of
the present state of the industry, other utility systems, although they are not
registered utility holding companies, span multiple states.(23) For example, the
PacifiCorp system covers portions of seven states (Annual Report of PacifiCorp
on Form 10-K for the year ended December 31, 1997), and the UtiliCorp system
covers portions of nine states (Form U-1 filed as of July 2, 1998).

       In addition to not specifying an absolute size for an "area" or "region,"
the 1935 Act likewise does not provide any specific parameters with respect to
the term "single" in the "single area or region" test. In considering distance,
the Commission has found that the combining systems need not be contiguous in
order for the requirement to be met. See, e.g., Conectiv, supra; cf. New Century
Energies, supra (finding that electric utilities located in two different power
pools, in two different reliability councils, in both the Eastern and Western
Interconnects, and with a physical separation of 300 miles were in same area or
region); Electric Energy, Inc.,

- -------------------------

       (21) NIPSCO, supra (in analyzing the single area or region requirement
for gas utility properties, the Commission noted that the acquisition would not
have "an adverse effect upon localized management, efficient operation or
effective operation."); accord, Sempra, supra.

       (22) In fact, as discussed in note 11 above, Applicants submit that the
integrated utility system requirement could be interpreted to involve only a
three-part test, with the last two tests read as one.

       (23) In this regard, Applicants believe that the continued economic
viability of large utility holding company systems suggests their efficient
operation and, accordingly, these systems should be evaluated on the same basis
as comparably large utility systems not regulated as registered utility holding
companies under the 1935 Act.



                                                                              73
<PAGE>   74

HCAR No. 13781 (Nov. 28, 1958) (utility assets were within the same area or
region as the acquirer's service area despite a distance of 100 miles crossing
two states); Mississippi Valley Generating Co., HCAR No. 12794 (Feb. 9, 1955)
(single area or region test met where generating station was located 150 air
miles from the territory served by the acquiring company).

       In tandem with not specifying the absolute size of an "area" or "region,"
the 1935 Act makes no reference to a set of pre-defined regions with specific
boundaries. It follows that the concept of region is not constrained by
geographical boundaries such as rivers or mountains; nor is it constrained by
regional designations which are part of the common vocabulary (e.g., northeast,
southwest, or midwest).

       The Commission's determination of whether the requirement is met is made
in light of "the existing state of the art of generation and transmission and
the demonstrated economic advantages of the proposed arrangement." Connecticut
Yankee Atomic Power Co., HCAR No. 14968 (Nov. 15, 1963); see also, Vermont
Yankee Nuclear Power Corp., HCAR No. 15958 (Feb. 6, 1968), rev'd and remanded on
other grounds, Municipal Elec. Ass'n v. SEC., 413 F.2d 1052 (D.C. Cir. 1969).
The Commission has applied flexibly the requirement based on the facts and
circumstances involved and the practicalities of the situation at hand. See,
e.g., Yankee Atomic, supra.

       The Division has recommended that the Commission "interpret the 'single
area or region' requirement flexibly, recognizing technological advances,
consistent with the purposes and provisions of the Act" and that the Commission
place "more emphasis on whether an acquisition will be economical." 1995 Report
at 66, 69. The Division has recognized that "recent institutional, legal and
technological changes . . . have reduced the relative importance of . . .
geographical limitations by permitting greater control, coordination and
efficiencies" and "have expanded the means for achieving the interconnection and
economic operation and coordination of utilities with non-contiguous service
territories." 1995 Report at 69. It has also recognized that the concept of
"geographic integration" has been affected by "technological advances on the
ability to transmit electric energy economically over longer distances, and
other developments in the industry, such as brokers and marketers." Id. Such
advances and developments are breaking down traditional boundaries and concepts
of regions. The Commission has confirmed its support for the Division's study,
citing, in particular, the Division's recommendation that the Commission
"continue to interpret the 'single area or region' requirement of [the 1935 Act]
to take into account technological advances." NIPSCO, supra; accord, Sempra,
supra.

       Prior to the Merger, the AEP System and the CSW System will be separated
by only 150 miles at their closest point, a distance which the Commission has
previously found acceptable under the single area or region test. The Combined
Company will operate in eleven contiguous states located in the mid-America
region of the United States, connected in the middle by the states of Arkansas
and Tennessee.(24)

- -------------------------

       (24) The concept of a geographic region, which includes the states in
which AEP and CSW are based (Ohio and Texas), exists within the electric
industry. In 1956, state regulators from 14 states, including Ohio and Texas,
formed the Mid-America Regulatory Conference. See Mid-America Regulatory
Conference, A History, 1956-1995.



                                                                              74
<PAGE>   75

       Moreover, that the Combined Company meets the single region test is
further supported by adopting a definition of region used by the Commission for
purposes of its size analysis under Section 10(b)(1). In Entergy, supra, the
Commission adopted the applicants' definition of the relevant region for Section
10(b)(1) purposes to include themselves and those electric utilities directly
interconnected with either or both. In today's increasingly competitive world,
AEP and CSW do not operate as isolated companies and their geographic region
should be analyzed in terms of their most accessible markets -- the
Interconnected Utilities. The service territories of these Interconnected
Utilities surround the Combined System and effectively close the distance
between the former AEP and CSW, bringing them even closer together.

       The Merger represents a logical extension of the AEP System's existing
service territory in light of contemporary circumstances. As the Commission has
recognized, the concept of area or region is not a static one and must be
refashioned to take into account the present realities of the electric industry,
consistent with the purposes of the 1935 Act. These present realities have
effectively shrunk the world in which the industry operates and support a
finding that the concept of a region can encompass four additional states more
than 50 years after the Commission's finding that the current seven-state AEP
System operates within an area or region.

       As the restructuring of the electric industry progresses, traditional
boundaries will become more blurred and the contours of regional markets will
change. Structural changes in a closely-related industry subject to similar
regulatory regimes, the natural gas industry, are influencing the restructuring
of the electricity industry and further breaking down traditional
boundaries.(25) Natural gas marketers, a new participant in the gas industry,
broke up old pipeline customer networks and demanded open access conditions,
fueling the industry's restructuring. See "Restructuring Energy Industries:
Lessons from Natural Gas," Energy Information Administration, Natural Gas
Monthly, May 1997 [hereinafter "Natural Gas Monthly"]. With the restructuring of
the gas industry, regional markets have become "interrelated" and the "stages
and operations of the natural gas industry have been integrated to an
unprecedented degree across North America." Natural Gas 1996 at 97. One of the
most recent innovations in the natural gas marketplace is the development of
market centers and hubs. Id. at x. At least 39 such centers were operating in
the United States and Canada by 1996, providing numerous interconnections and
routes to move gas from production areas to markets. Id. These market centers
have "made it easier for buyers to access the least expensive source of supply
and helped

- -------------------------

       (25) Restructuring of the natural gas industry started more than 10 years
ago, introducing competitive market forces into the industry's operations. See
Energy Information Administration, Office of Oil and Gas, Department of Energy,
Natural Gas 1996: Issues and Trends (December 1996) at xiii [hereinafter
"Natural Gas 1996"]. With the unbundling of pipeline company transportation and
sale services and the decontrol of natural gas wellhead prices over the last 20
years, the gas industry has responded by entering into new contractual
relationships, developing new services and new tools for managing risk and
creating a new participant -- the natural gas marketer. Id. at 1. Regulatory
restraints have been increasingly removed from the sale and transport of natural
gas, increasing the choices of participants in the natural gas industry, from
suppliers to consumers. Id. at ix. Energy markets for natural gas have become
increasingly competitive. Id. Regulatory changes seen in the interstate market
are being brought to the level of local distribution as state regulators promote
consumer choice in retail gas markets. Id. at 1, 113.



                                                                              75
<PAGE>   76

sellers to allocate gas to the highest bidding buyer." Id. at 78. Although it is
"probably premature . . . to conclude that a true North American market for
natural gas has emerged," market integration is improving and "regional clusters
of markets across certain broad areas seem to be highly competitive, even
between U.S. and Canadian markets." Id. at xii.

       Developments in the natural gas industry which are eroding traditional
boundaries are being applied to the electricity industry. Many gas marketers are
moving into the new electricity markets, and the development of financial
instruments used in the gas industry, such as spot, forward, futures, and
options contracts, are being imported into the electricity industry. Natural Gas
1996 at xiii. More than 100 energy marketing companies have registered with the
FERC to market electric power on a wholesale basis. Natural Gas Monthly. These
companies will be marketing retail power to retail power markets as well.
Moreover, the developments in electric and gas industries "may imply a close
relationship in the future for both industries." Natural Gas 1996 at xiii. Not
only are gas marketers entering the electricity markets, but "gas and electric
companies are forming mergers and strategic alliances to give customers menus
that allow buyers to bridge the differences between the industries." Id. And the
development of financial markets "may help to integrate the energy markets." Id.
In short, the concept of "area or region" should be interpreted flexibly to keep
pace with the current state of the industry.(26)

       Given the proximity of the AEP System to the CSW System and the present
technological ability to economically transmit power over longer distances, and
given that the Combined System will be economically operated as a single
integrated and coordinated system as described in Item 1.B.3, the Combined
Company satisfies the 1935 Act's requirement with respect to operating in a
"single area or region." The demonstrated economic advantages of the Merger
resulting in nearly $2 billion in net non-production savings and $98 million in
net fuel-related savings (as described below) also support the finding that the
single area or region test is met, consistent with the Commission's tradition of
balancing the various objectives of the 1935 Act. As discussed immediately
below, the size of the area or region in which the Combined Company will operate
will not result in the evils which the 1935 Act was meant to eliminate; namely,
it does not impair the advantages of localized management, efficient operation
or effective regulation.

- -------------------------

       (26) The breakdown of traditional boundaries is also seen in industries
beyond the utility industry. Technological advances, regulatory and legal
changes facilitating nationwide holding company acquisitions and nationwide
branching, and the entrance of nonbank providers of financial services have lead
to structural changes in the banking industry resulting in a trend toward
consolidation. In 1997, the number of interstate bank-to-bank mergers totaled
189. Bank Mergers: Hearings Before the House Banking and Financial Services
Comm., 105th Cong. 18-21 (1998) (statement of John D. Hawke, Jr., Treasury
Department Under Secretary for Domestic Finance). Similarly, the procompetitive,
deregulatory framework established by Congress in the Telecommunication Act of
1996 has removed the legal and economic barriers to the entry of
telecommunications firms into many markets. The Bell Atlantic-NYNEX merger
approved under the Telecommunications Act by the FCC resulted in Bell Atlantic
serving 13 states. The Effects of Consolidation on the State of Competition in

<PAGE>   77

       (iv) Localized Management, Efficient Operation and Effective Regulation

       Section 2(a)(29)(A), like Section 10(b)(1) discussed above, requires the
Commission to consider the size of the combined system. Section 2(a)(29)(A) has
been interpreted to require that the combined system must not be so large as to
impair (considering the state of the art and the area or region affected) the
advantages of localized management, efficient operation, and the effectiveness
of regulation. As the Commission stated in AEP, supra:

       [N]either section can be said to impose any precise limits on holding
       company growth. Both sections are couched in discretionary terms. They
       require the Commission to exercise its best judgment as to the maximum
       size of a holding company in a particular area, considering the state of
       the art and the area or region affected. In exercising its discretion,
       the Commission must balance the various objectives of the 1935 Act. The
       Commission stated in Commonwealth & Southern Corp., HCAR No. 7615 (Aug.
       1, 1947):

       We do not, in applying particular size standards, lose sight of the
objectives of other criteria. There must be a reconciliation of all objectives
to the end of accomplishing a satisfactory administration of the [1935] Act.
Thus we do not disregard operating efficiency in our determination of whether
size is excessive from the viewpoint of localized management or effectiveness of
regulation. As will be discussed below, difficult balancing decisions need not
be made because each prong of this standard is easily met. The size of the
Combined System does not impair the advantages of localized management,
efficient operation or the effectiveness of regulation. The Merger actually
increases the efficiency of operations.

       -      Localized Management

       The Commission has found that an acquisition does not impair the
       advantages of localized management where the new holding company's
       "management [would be] drawn from the present management" (Centerior,
       supra), or where the acquired company's management would remain
       substantially intact (AEP, supra). The Commission has noted that the
       distance of corporate headquarters from local management was a "less
       important factor in determining what is in the public interest" given the
       "present-day ease of communication and transportation." AEP, supra. The
       Commission also evaluates localized management in terms of whether a
       merged system will be "responsive to local needs." AEP, supra.

       The management of the Combined Company will be drawn primarily from the
       existing management of AEP and CSW and their subsidiaries. AEP will
       continue to maintain its system headquarters in Columbus, Ohio and will
       maintain the management structure of its combined subsidiary companies
       (including the electric operating and other subsidiary companies of CSW)
       essentially intact. CSW and AEP have operated with virtual service
       company management which has located management personnel in a number of
       operating locations throughout the service territories. In 1996, AEP
       reorganized into a centralized management structure with localized
       management remaining essentially in place, with the exception of the
       electric utility subsidiary headquarters operating management teams being
       realigned into either the Power Generation, Nuclear



                                                                              77
<PAGE>   78

       Generation, and Energy Delivery and Customer Relations business units.
       CSW completed a similar reorganization process in 1994.

       For example, at AEP, the subsidiary companies' generation operations were
       realigned into the Power Generation and Nuclear Generation business units
       while the transmission and distribution operations were realigned into
       the Energy Delivery business unit. As part of this realignment,
       transmission operations were structured with a centralized management and
       engineering organization which oversees three transmission operating
       regions. The distribution operations were structured with a centralized
       management and engineering structure which oversees 30 distribution
       districts which report to one of eight distribution regions. Customer
       services functions were also realigned under the Energy Delivery and
       Customer Relations business unit into a regional structure with four
       customer call centers, a single customer information system and
       centralized management of the customer service operations.

       As part of these individual reorganization efforts, the electric utility
       subsidiaries of AEP began doing business under the AEP brand without
       altering their separate legal identities, assets and liabilities,
       franchises and certificates of public convenience and necessity.
       Likewise, the electric utility subsidiaries of CSW retained their
       separate corporate identities, assets and liabilities, franchises and
       certificates of public convenience and necessity.

       Although the Applicants have just recently launched transition teams that
       are studying how the various components of the two organizations will be
       combined, the Applicants expect that the impact of the Merger will be
       predominantly confined to the merging of CSWS into AEPSC and the
       establishment of a business unit and management structure which looks
       very much like the existing structures of AEP and CSW. The electric
       utility subsidiaries will continue to operate through the regional
       offices with local service personnel and line crews available to respond
       to customers needs. The Combined Company will preserve the well
       established delegations of authority -- currently in place at AEP and CSW
       -- which permit the local, district and regional management teams to
       budget for, operate and maintain the electric distribution system, to
       procure materials and supplies and to schedule work forces in order to
       continue to provide the high quality of service which the customers of
       AEP and CSW have enjoyed in the past.

       The orders of the Oklahoma Commission, the Arkansas Commission, the
       Indiana Commission and the Kentucky Commission approving the Merger
       impose an extensive list of service quality standards on the utility
       operating companies operating within their states. In Oklahoma, the
       Oklahoma Commission established standards with respect to (i) customer
       service center calls, (ii) responses to requests for service, (iii)
       billing adjustments, (iv) customer satisfaction, and (v) reliability
       performance. The Louisiana Commission, in a service quality inquiry
       proceeding, has recently established customer service, staffing, and tree
       standards for SWEPCO. In Arkansas, Louisiana, Indiana, and Kentucky, the
       state commissions required that the Combined Company maintain or improve
       historical reliability performance levels. Moreover, the Texas Commission
       and the Louisiana Commission have recently been active in promoting
       utilities' responsiveness to customers and are expected to closely
       monitor the Combined



                                                                              78
<PAGE>   79

       Company's performance in this regard. See, e.g., Public Utility
       Commission of Texas Substantive Rule 25.21 et seq.; Louisiana Public
       Service Commission General Order of April 30, 1998.

       Likewise, the settlement with the staff of the Texas Commission contains
       service quality standards and provisions to ensure the continuity of
       CSW's local management and organizational structure following the Merger.
       For example, in Texas Applicants have agreed to (i) freeze CSW operating
       company field positions and customer service jobs until October of 2000,
       (ii) maintain a bargaining and decision-making presence in the CSW region
       with authority to enter binding agreements with wholesale customers up to
       at least $3 million, (iii) designate an employee who will act as a
       contact to the Texas Commission and consumer advocates seeking
       information regarding affiliate transactions and personnel transfers, and
       (iv) designate an employee or agent in Texas who will act as a contact
       for retail consumers regarding service and reliability concerns. In
       short, the customer service and field operations management structures of
       AEP and CSW, which are responsive to local needs, will be left
       essentially intact after the Merger. Accordingly, the advantages of
       localized management will not be impaired.

       -      Efficient Operation

       As discussed above in the analysis of Section 10(b)(1), the size of the
       Combined Company will not impede efficient operation; rather, the Merger
       will result in significant economies and efficiencies as described in
       Item 3.B.2 below. Economic dispatch (as described in Item 1.B.3) is more
       efficiently performed on a centralized basis because of economies of
       scale, standardized operating and maintenance practices and closer
       coordination of system-wide matters.

       Both AEP and CSW have efficient generating facilities that were recently
       noted by Public Utilities Fortnightly as being the fourth and sixth most
       efficient in the utility industry (September 1, 1998 report). In
       addition, AEP and CSW have consistently been rated in the top five
       utilities in the American Society for Quality and The University of
       Michigan Business Schools American Customer Satisfaction Index (ACSI). In
       the 1997 ACSI survey results which were published in the February 16,
       1998 issue of Fortune Magazine, CSW tied for second place and AEP tied
       for third place, out of more than 20 utilities surveyed. Because the
       Merger is expected to have little impact on field personnel in either
       power generation or transmission and distribution, AEP and CSW expect
       that the Combined Company will to continue to perform at these high
       efficiency levels.

       The divestiture of the Texas and Oklahoma generating assets will not
       adversely affect the Combined Company's ability to operate on an
       efficient basis. The Combined Company will coordinate the economic
       dispatch of generating units under its control, make economic purchases
       of power, and supply power to its customers. The fact that certain



                                                                              79
<PAGE>   80

       generating capacity will no longer be controlled by the Combined Company
       will not change the centrally coordinated, least-cost approach to
       operating the combined system.(27)

       -      Effective Regulation

       The Merger will not impair the effectiveness of regulation at either the
       federal or state level.

       On the federal level, the Combined Company will continue to be regulated
       by the Commission. The electric utility subsidiaries of the Combined
       Company will continue to be regulated by the FERC with respect to
       interstate electric sales for resale and transmission services, by the
       NRC with respect to the operation of nuclear facilities, and by the FCC
       with respect to certain communications licenses. The jurisdiction of
       other federal regulators is also not affected.

       FERC declined to set the issue of effectiveness of regulation for
       hearing. Indeed, the FERC concluded that Applicants had adequately
       addressed the FERC's concerns about its own jurisdiction and that state
       commissions could "impose in their own proceedings appropriate conditions
       to ensure that there is no impairment of effective regulation at the
       state level." 85 FERC at 61,821-822. Thus, FERC has already concluded
       that the Merger will not impair the effectiveness of regulation and that
       the issue does not merit further investigation.

       On the state level, the Commission has found that the effectiveness of
       regulation is not impaired where the same state regulators have
       jurisdiction both before and after a merger. See, e.g., Conectiv, supra;
       GPU, supra. In finding that regulation is not impaired, the Commission
       has also emphasized that the various state regulators have approved the
       combination. Entergy, supra. The electric utility subsidiaries of CSW
       will continue to be regulated by the state commissions of Arkansas,
       Louisiana, Oklahoma and Texas with respect to retail rates, service and
       related matters. The electric utility subsidiaries of AEP will continue
       to be regulated by the state commissions of Indiana, Kentucky, Michigan,
       Ohio, Tennessee, Virginia, and West Virginia with respect to retail
       rates, service and related matters.(28)

       (27) In fact, under the Texas Settlement, most of the generating capacity
being divested will be subject to recall by the Combined Company during peak
months to ensure that adequate capacity is available to serve native load. See
Texas Settlement Sec. 6.D-F.

       (28) The AEP and CSW management structures are designed to facilitate
communications and relationships with state regulators. Each company has
established State offices which have responsibility for regulatory,
environmental, and corporate communications and have other external relations
purposes. These state offices provide a single point of contact with each of the
state regulatory and environmental offices and have the responsibility for
handling all regulatory contacts, including making regulatory filings and
answering customer inquiries to the regulatory commissions. It is expected that
these offices will be left essentially intact after the Merger.



                                                                              80
<PAGE>   81
       The FERC's conclusion that the states will take appropriate action to
       protect their jurisdiction was correct.(29) The best evidence of this is
       that none of the state commissions which regulate the AEP and CSW utility
       subsidiaries has raised as an objection impairment of its ability to
       regulate the Combined Company after the Merger, or any other objection,
       in submissions to the Commission. In fact, the recent settlement in the
       Texas proceeding contains several provisions designed to ensure the
       effectiveness of the Texas Commission's regulatory authority over the
       Combined Company's operations in Texas. Among other things, these
       provisions include (i) a requirement that the Combined Company continue
       to comply with the Texas Commission's transmission pricing rules in
       ERCOT, (ii) a commitment by the Combined Company not to withdraw from
       either ERCOT or the SPP without the Texas Commission's prior approval,
       and (iii) a commitment that the Combined Company will not contend in any
       forum that the jurisdiction of the Texas Commission over any of CSW's
       operating companies located in Texas changed as a result of the Merger.
       Thus, rather than impairing the Texas Commission's regulatory authority,
       the settlement is specifically designed to safeguard that authority.

       Moreover, the Merger Agreement requires approvals from all regulatory
       authorities having jurisdiction over the Merger as a condition to the
       consummation of the Merger. The Merger has been approved by the state
       commissions in Oklahoma, Arkansas, Louisiana, Indiana and Kentucky.
       Applicants are working closely with other regulators (both state and
       federal) to obtain the remaining approvals (as described below in Item
       4).

       b.     Section 11(b)(1) (Acquisition of Non-Utility Interests)

       Section 11(b)(1) of the 1935 Act also requires that a registered holding
company limit its operations to a single integrated public utility system and
"such other businesses as are reasonably incidental, or economically necessary
or appropriate to the operations of such integrated public-utility system." Each
of CSW's non-utility business interests conforms to the "other business"
standards of the 1935 Act as previously determined by the Commission. The
indirect acquisition by AEP of CSW's non-utility businesses in no way affects
the functional relationship of these businesses to the Combined Company's core
electric business following the Merger. See Item 3.F below for a detailed
discussion on the acquisition by AEP of CSW's non-utility businesses.

       c.     Section 11(b)(2)

       Section 11(b)(2) of the 1935 Act directs the Commission "to ensure that
the corporate structure or continued existence of any company in the
holding-company system does not unduly

            (29) The Oklahoma, Kentucky, Arkansas, and Indiana Commissions
conditioned the approval of the Merger on Applicants' agreement not to assert in
proceedings before that state commission, or in court proceedings involving
orders of that state commission, that the authority of the Commission as
interpreted in Ohio Power v. F.E.R.C., 554 F.2d 779 (D.C. Cir. 1992) cert.

the reasonableness of non-power affiliate costs to be passed through to that
state's retail consumers. The Texas settlement contains a similar provision.



                                                                              81

or unnecessarily complicate the structure, or unfairly or inequitably distribute
voting power among security holders, of such holding-company system." The Merger
is consistent with Section 11(b)(2). The resulting capital structure is not
unduly complicated as discussed in Item 3.A.3 above. See, e.g., Sierra Pacific
Resources, HCAR No. 24566 (Jan. 28, 1988), aff'd Environmental Action, Inc., 895
F.2d 1255 (D.C. Cir. 1990) (Commission incorporates its Section 10(b)(3) capital
structure analysis into its Section 11(b)(2) corporate structure analysis).
Voting power is equitably and fairly distributed among the security holders of
each of AEP and CSW and their current subsidiaries, all of which have been
approved by the Commission in previous proceedings. The shareholders of AEP and
CSW, respectively, have overwhelmingly approved the shareholder actions
necessary to effect the Merger or the Merger itself.

       Immediately following the Merger, AEP will be a registered holding
company with respect to CSW, which, in turn, will be a registered holding
company with respect to the electric utility subsidiaries and other subsidiaries
it currently owns (with the exception of CSWS, which will be merged into AEPSC,
and CSW Credit, which will be directly held by the Combined Company). See
Exhibit E-6. Although it is intended that these interests will be restructured,
the final ownership structure has not yet been determined. Accordingly,
Applicants request that CSW survive as a holding company interposed between AEP
and the electric utility subsidiaries and a portion of the other subsidiaries it
currently owns for a period of up to eight years following the closing of the
Merger.

       Applicants have determined that the proposed transitional corporate
structure of the Combined Company following the Merger will be in the best
interests of the Combined Company's shareholders and ratepayers. The continued
existence of CSW as an intermediate holding company will result in AEP having a
tax basis in CSW equal to the aggregate tax basis of the CSW shareholders in CSW
prior to the Merger. This tax basis would be lost if CSW were not retained as an
intermediate holding company. See Exhibit J for an explanation of certain
relevant tax basis issues. Retaining the appropriate tax basis in CSW will allow
AEP to realize significant tax savings in the event that AEP were to divest CSW
assets in a future taxable transaction (although AEP does not at present have
any plan to divest CSW assets). Because the costs and complications associated
with the survival of CSW as an intermediate holding company are minimal, AEP and
CSW management have determined that the transitional structure will contribute
to the positive future financial condition of the Combined Company and will
maximize shareholder value.

       Although CSW will have an important economic purpose following the
Merger, CSW will have minimal operational functions. As an intermediate holding
company, CSW largely will be a conduit between AEP and its subsidiaries with
respect to capital contributions, if any, and dividends. The future management
of the Combined Company does not anticipate that CSW will be involved in any
intra-system financing other than maintaining its current guarantees on the
debts of its subsidiaries and participating in the Money Pool (as previously
authorized by the Commission) during the transitional period after the Merger to
the extent necessary. Moreover, the future management of the Combined Company
does not anticipate that CSW will engage in securities transactions (except as
noted in the previous sentence); acquire securities, utility assets or other
interests; or enter into or take any step in the performance of any service,
sales, or construction contract. CSW will continue to make, keep and preserve
accounts and records and make any required reports to the Commission and other
appropriate agencies.



                                                                              82
<PAGE>   83

       Under Section 10(c)(1) of the 1935 Act, the Commission must ensure that a
proposed acquisition subject to the Act will not be 'detrimental to the carrying
out of the provisions of Section 11.' Section 11(b)(2) mandates a simple
corporate structure for a registered holding company system. See, e.g., TUC
Holding Co., HCAR No. 26749, n. 20 (Aug. 1, 1997). Section 11(b)(2) includes two
principal restrictions. First, the Section requires registered holding companies
to take such action as the Commission finds necessary to ensure that registered
holding company systems ultimately are restructured to include no more than two
tiers of holding companies. Second, the Section directs the Commission to
evaluate the facts and circumstances 'to ensure that the corporate structure or
continued existence of any company in the holding-company system does not unduly
or unnecessarily complicate the structure . . . of such holding-company system.'

       As discussed below, the transitional corporate structure of the Combined
Company, in which AEP and CSW will survive as first and second tier holding
companies, respectively, in the Combined Company's holding company system, will
be consistent with the requirements of Section 11(b)(2).(30) Corporate
structures including two tiers of holding companies are specifically envisioned
under the 1935 Act and its Rules, and, in this case, the existence of two
registered holding companies in one system will not result in unnecessary or
undue complications. To the contrary, the minimal complications that may be
introduced by the continued existence of CSW are necessary and appropriate in
serving the interests of the Combined Company, its shareholders and ratepayers.

              (i)    The Existence of Two Tiers of Registered Holding Companies
                     in a Single Integrated Public-Utility System Is Not
                     Prohibited under the 1935 Act

       The 1935 Act was passed, in large part, to curb abuses identified by
Congress arising out of 'the utilization of highly-pyramided and complex holding
company systems as a means of controlling and exploiting utility operating
companies, as well as companies in non-utility fields . . . .' Vermont Yankee
Nuclear Power Corp., HCAR No. 15958 (Feb. 6, 1968), rev'd and remanded on other
grounds, Municipal Elec. Ass'n v. SEC, 413 F.2d 1052 (D.C. Cir. 1969)
[hereinafter 'Vermont Yankee']. Holding companies 'piled on top of holding
companies result[ed] in highly leveraged corporate structures of extraordinary
complexity.' AEP.

       In addressing these perceived abuses, however, Congress did not prohibit
holding companies entirely. Rather, it required the Commission to take such
action as necessary to ensure that each registered holding company system be
restructured to include no more than two

            (30) Applicants note that SWEPCO, a wholly owned electric
public-utility operating subsidiary of CSW, is technically a registered holding
company under the 1935 Act by virtue of its 47.6% ownership interest in a
company (which technically is an 'electric utility company' under the 1935 Act)
whose assets at the end of 1997 accounted for approximately .02% of SWEPCO's
total assets (based on SWEPCO's and its subsidiary's total assets at year-end
December 31, 1997, and November 30, 1997, respectively). Applicants acknowledge
that questions could be raised under Section 11(b)(2) if SWEPCO were to remain a
holding company within the Combined Company following the Merger. Accordingly,
Applicants hereby commit to take appropriate action to eliminate SWEPCO's
holding company status following the Merger.


                                                                              83
<PAGE>   84

tiers of holding companies through the 'great-grandfather clause' of Section
11(b)(2).(31) The legislative history of the 1935 Act confirms that Congress's
express authorization of two tiers of holding companies in a registered holding
company system was consistent with its intent in passing the 1935 Act. While the
version of the 1935 Act originally passed by the Senate contained a provision,
Section 11(b)(3), that required that within five years all holding companies
should cease to be holding companies unless the equivalent of a certificate of
convenience and necessity were obtained from the Federal Power Commission, see
American Power & Light Co. v. SEC, 329 U.S. 90, 146, 147 (1946) (citing to S.
2796, 74th Cong., 1st Sess.), the bill that became law replaced this section
with the 'great-grandfather clause' of Section 11(b)(2). See 79 Cong. Rec. 14620
(August 24, 1935).

            The 1935 Act is silent regarding whether a registered holding
company system with two tiers of holding companies is limited to one registered
holding company. However, the Commission's Rules promulgated under the 1935 Act
expressly envision a holding company system with more than one registered
holding company. Rule 1(c) provides that 'where any holding company system
includes more than one registered holding company, the annual report shall be
filed by the top registered holding company in such system.' Similarly, the
instructions to Form U5S (relating to holding company annual reports) track the
requirements of Rule 1(c), defining 'holding company system' to mean 'the parent
registered holding company together with all its subsidiary companies, including
all subsidiary registered holding companies.'(32) See also, Rule 87(c)
(providing that, in the context of service, sales, and construction contracts,
it is Rule 85, as opposed to Rule 87, that is applicable to a 'subsidiary which
is itself a registered holding company'). In summary, the transitional corporate
structure of the Combined Company, which includes AEP as the top registered
holding company and CSW as a subsidiary registered holding company, satisfies
the first requirement of Section 11(b)(2).



- ----------------

            (31) The 'great-grandfather clause' of Section 11(b)(2) provides
that 'the Commission shall require each registered holding company (and any
company in the same holding-company system with such holding company) to take
such action as the Commission shall find necessary in order that such holding
company shall cease to be a holding company with respect to each of its
subsidiary companies which itself has a subsidiary company which is a holding
company.' See also, Entergy, supra, ('Section 11(b)(2) allows three tiers of
companies in a registered holding company system.').

            (32) Rule 1, adopted in 1941, was amended in 1951 to include the
current formulation of subsection (c). HCAR No. 10432 (Mar. 12, 1951). Prior to
1951, each registered holding company in a holding company system was required
to file its own separate annual report on Form U5S. Id. The current formulation
of Rule 1(c) was adopted one year before the Commission 'largely completed' its
task of 'simplifying and reorganizing the complex financial and corporate
structures of holding company systems as required by section 11.' See 1995
Report at viii. Since 1951, the Commission has amended Rule 1 twice, without
altering the language of Rule 1(c). See HCAR No. 17435 (Jan. 25, 1972) (imposing
a filing fee for Form U5S); HCAR No. 26575 (Sept. 17, 1996) (removing the filing
fee). As late as 1984, the Commission, in adopting amendments to Form U5S,
specifically recognized the existence of Rule 1(c) and its requirement that the
'annual report be signed by each registered holding company in the system.' HCAR
No. 23214 (Feb. 2, 1984) (emphasis added) (amending Form U5S to clarify that an
exempt subsidiary holding company, as opposed to a registered subsidiary holding
company, need not sign the annual report.).



                                                                              84
<PAGE>   85

              (ii)   The Existence of CSW Will Not Unduly or Unnecessarily
                     Complicate the Structure of the Holding Company System

       The second prong of Section 11(b)(2) requires that the Commission ensure
that 'the corporate structure or continued existence of any company in the
holding-company system does not unduly or unnecessarily complicate the structure
 . . . of such holding-company system.' The existence of a subsidiary holding
company does not run afoul of Section 11(b)(2) merely because it causes the
structure of the holding company system to be more complicated. Rather, the
existence of a company violates Section 11(b)(2) only if it causes unnecessary
or undue complications. The Commission has interpreted Section 11(b)(2) to
require the elimination of any holding company that serves no useful purpose or
economic function. See, e.g., WPL Holdings, Inc., HCAR No. 25377 (Sept. 18,
1991); Peoples Gas Light and Coke Co., HCAR No. 15929 (Dec. 22, 1967); Voting
Trustees of Granite City Generating Co., HCAR No. 14739 (Nov. 5, 1962).

       In prior proceedings, the Commission has determined that the existence of
a second tier holding company satisfies the Section 11(b)(2) test. See, e.g.,
Entergy, supra (the Commission found that the addition of an exempt sub-holding
company to a registered holding company system did not create an undue or
unnecessary corporate complexity); Cinergy Corp, HCAR No. 26146 (Oct. 21, 1994)
(the Commission approved a merger where a registered holding company would be
the parent of an exempt holding company). Moreover, the Commission has in other
circumstances allowed a holding company system with two tiers of registered
holding companies. See Annual Report on U5S of Central and South West
Corporation and Southwestern Electric Power Company for year ended December 31,
1997 (Central and South West Corporation and its wholly owned subsidiary,
Southwestern Electric Power Company, are both registered holding companies);
Citizens Utilities Company, HCAR No. 25331 (June 14, 1991) (Louisiana General
Services, Inc. and its wholly owned subsidiary, LGS Pipeline, Inc., were both
exempt, registered holding companies prior to a merger).

       In this case, the temporary survival of CSW as a holding company will
result in minimal complications. CSW will not perform any significant
operational functions. Although it will continue to guarantee the indebtedness
of its subsidiaries and make borrowings to fund the Money Pool and for other
subsidiaries as previously authorized by the Commission to the extent necessary
during the transitional period following the Merger, it will largely function as
a conduit between the Combined Company and the CSW subsidiaries. The Applicants
anticipate that CSW will not engage in securities transactions (except as noted
in the previous sentence); acquire securities, utility assets or other
interests; or enter into or take any step in the performance of any service,
sales, or construction contract. One of the complications that might have
arisen, the need to file two annual reports, has been eliminated by Rule 1(c).

       These minimal complications are neither 'unnecessary' nor 'undue.' To the
contrary, any minor complications, and any negligible expenses resulting
therefrom, are necessary to assure appropriate tax and accounting treatment and
to preserve the potential for significant tax savings. The survival of CSW will
benefit the Combined Company's shareholders and its ratepayers. The



                                                                              85
<PAGE>   86

transitional structure certainly will not result in a 'highly-pyramided and
complex holding company system' at odds with the purposes of the 1935 Act.(33)
Vermont Yankee, supra.

       In sum, the 1935 Act itself and the Rules thereunder, the policies behind
the Act, and the basic Commission interpretations of Section 11(b)(2), all point
to an obvious conclusion: the transitional survival of CSW is consistent with
the standards of Section 11(b)(2). Nevertheless, additional discussion of the
role of tax considerations under the Commission's interpretation of the 1935 Act
is helpful in light of several cases decided by the Commission in the
early-1950s and before. Not only are these cases distinguishable from the case
at hand, but other cases serve to support the conclusion that the Applicants
meet the standards of Section 11(b)(2).

              (iii)  CSW Will Perform a Useful Economic Purpose by Preserving
                     Appropriate Tax Treatment Resulting from the Merger, and
                     its Survival for Such Purpose Does Not Delay or Disrupt the
                     Commission's Administration of the 1935 Act

       The structuring of business activities for tax planning purposes is not
inimical to public policy considerations and is a legitimate goal under the 1935
Act. As the Commission has held, the realization of tax savings through a
transaction often helps to satisfy the requirements of the 1935 Act. See, e.g.,
Columbia Gas System, HCAR No. 26536 (June 25, 1996) (Commission noted that the
applicants expected the merger to produce economies and efficiencies, including
the realization of state tax benefits); TransTok, HCAR No. 26421 (Nov. 30, 1995)
(Commission noted that the benefits and efficiencies of the merger included
annual tax savings); New England Power Association, 1 SEC 473 (May 16, 1936)
(Commission noted that the acquisition should result in tax and other
economies). The Commission has authorized the acquisition of subsidiaries
organized, among other things, 'as a part of tax planning in order to limit [a
registered holding company's] exposure to U.S. and foreign taxes.' Cinergy, HCAR
No. 26376 (Sept. 21, 1995); see also, Allegheny Power System, HCAR No. 26401
(Oct. 27, 1995).

       The Commission has found that an entity can serve a useful purpose or
function through its ability to provide shareholders with tax advantages. See
Standard Power and Light Corporation, HCAR No. 13101 (Feb. 16, 1956), enforced,
United States District Court for



- --------------

            (33) The Commission has in recent years recognized that registered
holding companies may organize subsidiaries, including intermediate
subsidiaries, for various business and legal purposes. See, e.g., Exemption of
Acquisition by Registered Public-Utility Holding Companies, HCAR No. 26667 (Feb.
14, 1997) (modifying proposed Rule 58 to allow a registered holding company
system to use an intermediate subsidiary to invest in energy-related companies,
noting that use of such an intermediate subsidiary "could further insulate the
holding company and its other subsidiaries . . . from any direct losses that
could occur with respect to Rule 58 investments"); 1995 Report at 94 (noting
that in the 1980s and 1990s, registered holding companies expanded their use of
separate subsidiaries to engage in other activities, including the formation of
EWGs and FUCOs); Cinergy, HCAR No. 26376 (Sept. 21, 1995) (authorizing the
acquisition of subsidiaries organized, in part, for tax planning purposes).
Similarly, Applicants' proposal to retain CSW as an intermediate holding company
is for a legitimate business purpose, to preserve appropriate tax treatment of
certain corporate transactions that may occur in the future.



                                                                              86

District of Delaware (Order, Mar. 13, 1956) (the Commission modified its order
directing a registered holding company to liquidate and dissolve, where the
holding company could transform itself into an investment company and serve a
useful purpose by providing shareholders with tax advantages). Moreover, the
Commission has implied that a useful purpose for a holding company is to
facilitate tax advantages by citing the lack of tax advantages as a factor in
its determination that a holding company should be dissolved. United Light &
Power Company, HCAR No. 6603 (Apr. 30, 1946) (the Commission found that 'there
[wa]s no need for the continued existence' of a registered holding company, in
part, because the holding company's existence no longer offered tax advantages
due to changes in the tax laws).

       The Commission has 'recognized the importance of tax considerations'
under Section 11 and has 'sought to cooperate in achieving that type of
rearrangement [under Section 11] which imposes the least tax burden on the
company and the security holders, so long as the choice does not result in
frustrating the Act or in delaying the attainment of its objectives.' Engineers
Public Service Co., HCAR No. 7041 (Dec. 19, 1946); cf. Standard Power & Light,
HCAR No. 12208 (Nov. 9, 1953) (Commission allowed holding company, subject to a
liquidation and divestment order, to divest itself of only a portion of the
interests in its subsidiary to preserve tax advantages because such a plan did
not, under the circumstances, delay or interfere with compliance with the 1935
Act). The existence of tax savings is a compelling reason to maintain a given
structure under Section 11(b)(2), provided that 'the continued existence of this
[security] structure will not be detrimental to the public interest or the
interest of investors or consumers.' Community Gas and Power Company, HCAR No.
4915 (Mar. 4, 1944).

       The continued existence of CSW will serve a useful function in the
holding company system by facilitating appropriate tax treatment and by
preserving potentially significant tax savings. These savings are a compelling
reason for the transitional survival of the CSW holding company, and the
existence of CSW will not be detrimental to the public interest, the interest of
investors or consumers, or the Commission's administration of the 1935 Act.

       Finally, it should be noted that in a few proceedings in the 1940's to
early-1950's, the Commission determined that potential tax benefits (to only or
potentially only a portion of the shareholders and, in one case, where the
benefits could be achieved by other means), taken alone, were not sufficient to
justify relief from dissolution findings and orders or commitments that had been
made in the early stages of implementation of the 1935 Act. See Engineers Public
Service Company, HCAR No. 7041 (Dec. 19, 1946); Electric Bond and Share Company,

Stockholders v. SEC, 184 F.2d 646 (2nd Cir. 1950).(34) These decisions are not

States District Court for District of Oregon (Order, June 29, 1946), aff'd, 162
F.2d 618 (9th Cir. 1947), the Commission, reviewing proposed plans of
reorganization under Section 11(f), found that the continued existence of a
shell holding company solely for the purpose of seeking tax advantages not then
available under applicable law was inimical to the standards of Section
11(b)(2). Here, by contrast, the economic and tax benefits sought by the
retention of CSW as a sub-holding company will accrue under the presently
existing tax laws.


                                                                              87

not identified any unnecessary or undue complication that would result from the
post-Merger transition structure the potential tax savings would inure to the
Combined Company itself for the benefit of all shareholders alike.

       The temporary survival of CSW as a registered holding company to further
the interests of the Combined Company, its shareholders and ratepayers, will
meet all of the standards of the 1935 Act. The transitional corporate structure
will not create unnecessary or undue complications under Section 11(b)(2), and
the significant, potential tax savings outweigh any negligible complications and
costs associated with CSW's survival.

       2.     Section 10(c)(2)

       Section 10(c)(2) requires that the Commission approve a proposed
transaction if it will serve the public interest by tending towards the
economical and efficient development of an integrated public utility system. For
the reasons discussed above, the Combined System will be integrated. The Merger
will also tend towards the economic and efficient development of the Combined
System. This Section 10(c)(2) standard is met where the likely benefits of the
acquisition exceed its likely costs. City of Holyoke, supra.

       Economic efficiency is the driving force behind the Merger; its purpose
is to create an entity well situated to compete effectively in an increasingly
active market. Applicants project $1,966 million of net non-fuel cost savings
over the ten-year period immediately following consummation of the Merger. These
savings will be passed on to shareholders and customers of the Combined Company.
Based upon the resolution of issues related to the allocation of Merger-related
savings between customers and shareholders of the Combined Company in the states
which have approved the Merger, Applicants have guaranteed that approximately
55% of the projected savings from the Merger will be passed through to the
respective customers of each of the Combined Company's utility operating
companies, regardless of whether these actual merger-related savings are
achieved. Applicants also anticipate net fuel-related savings of approximately
$98 million over this same period that will be passed on to customers. Thus, the
Merger will allow the Combined Company to realize the "opportunities for
economies of scale, the elimination of duplicate facilities and activities, the
sharing of production capacity and reserves and generally more efficient
operations" described by the Commission in AEP, supra.

       The nonproduction cost savings resulting from the Merger are set forth in
the testimony of Thomas J. Flaherty before the Texas Commission, a copy of which
is included in Exhibit D-5.1 and incorporated by reference. As explained by Mr.
Flaherty, the Combined Company is expected to achieve the following
nonproduction costs savings:

(a) Does not include contingent change in control payments.

       Assuming a March 31, 1999 closing, AEP and CSW estimate available
synergies and cost savings resulting from the Merger, net of costs necessary to
achieve these reductions, for each of the first ten years following the Merger
of approximately $17 million (9 months), $102 million, $135 million, $162
million, $181 million, $243 million, $255 million, $259 million, $267 million,
$275 million and $70 million (3 months), respectively, for a total of $1,966
million. The savings in the first five years are expected to be lower than in
the later years due to the costs incurred to achieve the savings. Of the $1,966
million in total anticipated net savings, Applicants estimate that approximately
$713 million of the total savings will be allocated to the pre-Merger CSW and
approximately $1,253 million will be allocated to pre-Merger AEP. Moreover, even
though the savings are shown over 10 years only, it is expected that some of
these savings will continue to be realized over a much longer period. See
Testimony of Thomas J. Flaherty included in Exhibit D-5.1.

       The Applicants' estimates of Merger savings have been provided to the
staffs of all eleven state commissions which will have retail rate jurisdiction
over the Combined Company (Arkansas, Indiana, Kentucky, Ohio, West Virginia,
Michigan, Tennessee, Virginia, Louisiana, Oklahoma and Texas). In each of those
states, the Applicants have responded to discovery requests from participants,
and have defended the proposed level of savings as being achievable. In each of
those states, the Applicants have either received state commission orders or
entered into stipulations with the commission's staff (and other parties) which
establish the level of savings that will be shared with ratepayers and which
guarantee to consumers the savings regardless of whether they are achieved. The
amount of the savings as well as Applicants' plans for allocating the savings
have been approved by the state commissions of Arkansas, Louisiana, Indiana,
Kentucky, and Oklahoma.

       Based upon the resolution of issues related to the allocation of Merger
related savings between customers and shareholders of the Combined Company in
the states which have approved the Merger, Applicants have guaranteed that
approximately 55% of the projected savings from the Merger will be passed
through to the respective customers of each of the Combined Company's utility
operating companies. For example, the settlement with the staff of the Texas
Commission includes rate reductions totaling $221 million over six years for
CSW's three utility subsidiaries operating in the state. Similarly, the Oklahoma
Commission issued an order approving the Merger as being in the "public
interest," freezing base rates through 2003 and requiring 55% of Oklahoma's
share of Merger-related savings to be recovered by ratepayers in Oklahoma. In
addition, Applicants have agreed to make a $5,000,000 reduction to the revenue
requirement otherwise determined by the Oklahoma Commission to be reasonable in
the event they seek a rate review any time after January 1, 2003 through the end
of the fifth year after the effective date of the Merger.

       The Arkansas Commission issued an order approving the Merger as being in
the "public interest" and providing a total rate cut of $6 million over the
five-year period following the Merger.



                                                                              89
<PAGE>   90

       In Louisiana, Applicants agreed to a base rate freeze for 5 years and a
nonfuel savings sharing mechanism ("SSM") for eight years, which is a
formula-based methodology to be used to quantify merger savings. During the
first 14 months following the consummation of the Merger, the Combined Company
will retain 100% of the Merger savings and may use savings to reduce deferrals
of the Merger costs. Beginning in the 15th month, 50% of the Merger savings as
computed pursuant to the SSM will be passed through to consumers in Louisiana.
The SSM will be updated annually and continue for the remainder of the
eight-year period following the Merger's consummation. Applicants have estimated
that the customer rate credits in Louisiana will total more than $18 million
over the eight-year period.

       Likewise, Merger-related savings plans have been approved by the state
commissions of Indiana and Kentucky. The order of the Indiana Commission
provides for a credit to ratepayers of approximately 55% of the $121.2 million,
or $66.6 million, of Merger savings expected to be achieved over the first eight
years following the Merger. The order of the Indiana Commission further provides
for an extension of an existing rate freeze to January 1, 2005. The order of the
Kentucky Commission establishes merger savings of approximately $51.6 million
over the first eight years following the Merger, with consumers receiving the
benefit of approximately $28.4 million, or 55% of the total savings. Moreover,
the order of the Kentucky Commission provides that Kentucky Power, AEP's utility
subsidiary, will not request an increase in its existing base rates until the
later of January 1, 2003, or three years from the effective date of the Merger.
Although specific determinations of the net savings to each group in the
remaining states cannot be finalized until all regulatory proceedings have been
completed, it is expected that each group will realize approximately 55% of the
net savings.

       In the states that have approved the Merger, Applicants have agreed to
mechanisms for sharing the savings which utilize the Applicants' estimate and
provide guaranteed net rate reduction riders for periods ranging from five to
eight years. In other words, if the Applicants do not achieve the estimated
level of savings, the consumers will nonetheless obtain the benefits of the
estimated Merger savings. This provides the requisite incentive for Applicants
to achieve the estimated Merger savings.

       The staffs of the Texas and Oklahoma Commissions support Applicants'
divestiture of generation assets given the mitigation measures that Applicants
have proposed to protect ratepayers. As part of the settlement in Texas, the
Texas commission staff, the Office of Public Utility Counsel, and the other
settling parties agreed to several significant provisions designed to protect
consumers from the economic effects of the divestiture, including (i) a
requirement that proceeds from the divestiture be used to reduce stranded costs
of the Combined Company, (ii) a provision that limits any adverse impact on
consumers related to the divestiture of the units, and, most significantly, and
(iii) a provision that guarantees rate reductions totaling $221 million to the
Combined Company's ratepayers in Texas over the six years following the Merger.

       In Oklahoma, as part of the stipulation approved by the Oklahoma
Commission, the Applicants committed to hold Oklahoma retail consumers harmless
from adverse effects related to CSW's divestiture of 300 MW of generation
capacity in Oklahoma. Applicants agreed to make an "after the fact" calculation
of margins both before and after the divestiture. If negative margins result,
Oklahoma consumers will be held harmless from the additional costs associated
with the divestiture.

                                                                              90
<PAGE>   91

       Applicants estimate that the Combined Company will also realize
approximately $98 million in net fuel-related savings over the same 10 year
period. J. Craig Baker's testimony before the FERC (a copy of which is included
in Exhibit D-1.1 and is incorporated by reference) explains that these savings
will result from the central coordinated dispatch of energy by the Combined
Company. These savings will be realized by customers.

       These expected savings exceed the anticipated savings in a number of
other acquisitions approved by the Commission. See, e.g., New Century Energies,
supra (expected savings of $770 million over 10 years); Entergy, supra (expected
savings of $1.67 billion over ten years); Northeast I, supra (estimated savings
of $837 million over 11 years); IE Industries, HCAR No. 25325 (June 3, 1991)
(expected savings of $91 million over ten years); CINergy, supra (estimated
savings of approximately $895 million over ten years).

       As the Commission has observed, with reference to the requirement of
Section 10(c)(2) that a proposed combination yield economies and efficiencies,
"specific dollar forecasts of future savings are not necessarily required; a
demonstrated potential for economies will suffice even when these are not
precisely quantifiable." Centerior, supra (citation omitted). In this regard,
the Merger will result in additional benefits which, although not precisely
quantifiable, are nonetheless significant.

       Two of these principal additional benefits relate to the Combined
Company's generation mix and system reliability. The Merger will result in a
more balanced generation mix that is less susceptible to fuel price volatility
and supply interruptions. In addition, the Combined System will be better
situated to provide more reliable electric service than is possible for AEP and
CSW on a stand-alone basis. For example, the Combined System will share in a
larger generating base after the Merger. As a result, the Combined System will
have more generating resources to call on when units are down for maintenance or
due to an unscheduled outage. In addition, each of AEP and CSW has a higher risk
of unserved load than would be the case for the Combined System, since each of
AEP and CSW on a stand-alone basis has access to fewer interconnections to
neighboring systems for emergency support.

       C.     SECTION 10(f)

       Section 10(f) provides that:

       The Commission shall not approve any acquisition as to which an
       application is made under this section unless it appears to the
       satisfaction of the Commission that such State laws as may apply in
       respect of such acquisition have been complied with, except where the
       Commission finds that compliance with such State laws would be
       detrimental to the carrying out of the provisions of section 11.

       Each of AEP's and CSW's obligation to consummate the Merger is
conditioned, among other things, on the receipt of all requisite state
regulatory approvals. State regulatory approvals have been obtained from the
Oklahoma Commission, the Arkansas Commission, the Indiana Commission, and the
Kentucky Commission. Applicants have also reached a settlement with the staffs
of the Texas Commission and the Louisiana Commission who support the Merger as
being in the public interest. See Item 4, infra, for further discussion of
regulatory approvals and the




                                                                              91
<PAGE>   92

standard of review applicable to such approval. When the other approvals have
been obtained, the Merger will comply with Section 10(f).

       D.     INTRA-SYSTEM FINANCING AND OTHER COMMISSION AUTHORIZATIONS.

       In order to maximize the efficiencies resulting from the Merger, the
Applicants seek authority for the Combined Company to reorganize, consolidate
and, where necessary, restate certain of the intra-system financing and other
authorizations previously issued by this Commission to each of AEP, CSW, and
their respective subsidiaries, as discussed in more detail below.

       Applicants request approval, effective upon consummation of the Merger,
to merge CSWS with and into AEPSC. Applicants request that, upon the merger of
CSWS into AEPSC, AEPSC succeed to certain of the authority of CSWS as set forth
in various Commission orders (which orders are summarized in Exhibit I-1
attached hereto) and that such activities with respect to CSWS include AEPSC.

       Certain of the non-utility businesses of CSW (each a 'CSW Non-utility
Business') conduct activities that are substantially equivalent to the
activities of one or more non-utility subsidiaries of AEP (each an 'AEP
Non-utility Business'). Applicants request approval, as deemed appropriate by
management, for the Combined Company to directly or indirectly acquire, and for
CSW to transfer to the Combined Company, CSW Non-utility Businesses through: (1)
merger of one or more CSW Non-utility Businesses with one or more wholly owned
non-utility subsidiaries (either presently existing and performing substantially
equivalent activities or to be formed, if appropriate) of the Combined Company
(each a 'Combined Non-utility Business'), (2) the dividending or distribution of
the common stock of one or more CSW Non-utility Businesses from CSW to the
Combined Company, or (3) the acquisition of the assets or common stock of one or
more CSW Non-utility Businesses by one or more Combined Non-utility Businesses.
Applicants request approval, if management deems appropriate, to consolidate
each CSW Non-utility Business with its corresponding AEP Non-utility Business
into a single Combined Non-utility Business directly or indirectly owned by the
Combined Company. Applicants request approval for the Combined Company to
transfer to CSW, and CSW to acquire, any AEP Non-utility Business or to
consolidate any AEP Non-utility businesses with and into any like CSW
Non-utility Business consistent with the foregoing principles and authority.
Applicants request that upon consolidation, each resulting Combined Non-utility
Business succeed to all of the authority of each corresponding CSW Non-utility
Business and AEP Non-utility Business, respectively, as set forth in previously
issued Commission orders. The determination of the appropriate corporate
structure of the Combined Company is the subject of currently convoked Merger
transition teams.

       Pursuant to American Elec. Power Co., HCAR No. 26864 (Apr. 27, 1998) and
American Elec. Power Co., HCAR No. 26516 (May 10, 1996), this Commission
authorized AEP to issue and sell securities up to 100% of its consolidated
retained earnings for investment in EWGs and FUCOs. Pursuant to Central and
South West Corp. et al., HCAR No. 26653 (Jan. 24, 1997), this Commission
authorized CSW to issue and sell securities up to 100% of its consolidated
retained earnings for investment in EWGs and FUCOs. Applicants propose that,
upon




                                                                              92
<PAGE>   93
consummation of the Merger, the authority of CSW to issue and sell securities in
an amount up to 100% of its consolidated retained earnings for investment in
EWGs and FUCOs as provided by Central and South West Corp. et al., HCAR No.
26653 (Jan. 24, 1997) shall cease. To the extent that AEP and CSW were
authorized, pursuant to Sections 32 and 33 of the 1935 Act and the rules
thereunder, to invest up to 100% of their consolidated retained earnings in EWG
and FUCO interests, the Combined Company should also be authorized to invest up
to 100% of its combined consolidated retained earnings in EWG and FUCO
interests. Applicants therefore propose that, upon consummation of the Merger,
the authority of the Combined Company to issue and sell securities in an amount
up to 100% of its consolidated retained earnings for investment in EWGs and
FUCOs shall be the same as that provided by American Elec. Power Co., HCAR No.
26864 (Apr. 27, 1998) and American Elec. Power Co., HCAR No. 26516 (May 10,
1996), except that for purposes of determining the amount of consolidated
retained earnings as contemplated by American Elec. Power Co., HCAR No. 26864
(Apr. 27, 1998) and American Elec. Power Co., HCAR No. 26516 (May 10, 1996),
'consolidated retained earnings' shall consist of the consolidated retained
earnings of the Combined Company.

       Currently, the CSW System uses short-term debt, primarily commercial
paper, to meet working capital requirements and other interim capital needs. In
addition, to improve efficiency, CSW has established a system money pool (the
'Money Pool') to coordinate short-term borrowings for CSW, its U.S. electric
utility subsidiary companies and CSWS, as set forth in various Commission orders
(which orders are summarized in Exhibit I-2 attached hereto). AEP has no
equivalent to the Money Pool. Applicants hereby request authorization, upon
consummation of the Merger and on the same terms and conditions as set forth in
the orders summarized in Exhibit I-2, to permit: (1) the Combined Company, AEP's
U.S. electric subsidiary companies and AEPSC to participate in the Money Pool,
and (2) the Combined Company to manage and to fund the Money Pool. Exhibit I-2
summarizes the existing authority associated with the Money Pool and states the
additional authority requested for the Money Pool upon consummation of the
Merger. Applicants request that following the Merger, both the Combined Company
and CSW (for a transitional period) will have in aggregate the authority that
CSW has with respect to those orders summarized in Exhibit I-2.

       CSW Credit purchases, without recourse, the accounts receivable of CSW's
U.S. electric utility subsidiary companies and certain non-affiliated utility
companies. The sale of accounts receivable provides CSW's U.S. electric utility
subsidiary companies with cash immediately, thereby reducing working capital
needs and revenue requirements. In addition, because CSW Credit's capital
structure is more highly leveraged than that of the CSW U.S. electric utility
subsidiaries and due to CSW Credit's higher short-term debt ratings, CSW's
overall cost of capital is lower. CSW Credit issues commercial paper to meet its
financing needs. Applicants hereby request approval, effective upon consummation
of the Merger, for the Combined Company to directly acquire, and for CSW to
transfer to the Combined Company, the business of CSW Credit through: (1) the
merger of CSW Credit with a subsidiary of the Combined Company to be formed, if
appropriate, (2) the dividending or distribution of the common stock of CSW
Credit from CSW to the Combined Company, or (3) the acquisition of the assets or
common stock of CSW Credit by a subsidiary of the Combined Company to be formed,
if appropriate. Applicants request that, upon the acquisition of the business of
CSW Credit by the Combined Company, the resulting company ('New Credit') succeed
to all of the authority of CSW Credit as set forth in various Commission orders
(which orders are summarized in Exhibit



                                                                              93
<PAGE>   94

I-3 attached hereto). Exhibit I-3 summarizes the existing authority of CSW
Credit and states the authority requested for New Credit.

       CSW has supported the financing and other activities of its subsidiaries
through obtaining Commission approval to issue and guarantee certain
indebtedness. After the Merger it may be more efficient or even commercially
necessary for the Combined Company to support certain of the financing
arrangements and business activity previously supported by CSW. Applicants
hereby request approval for the Combined Company, upon consummation of the
Merger, to support those financing and other activities presently supported by
CSW, including the issuance and guaranteeing of indebtedness, pursuant to those
orders of the Commission summarized in Exhibit I-4. Exhibit I-4 describes the
existing authority of CSW which Applicants seek to duplicate in favor of the
Combined Company. It is Applicants' intention that, following the Merger, both
the Combined Company and CSW will simultaneously have in aggregate the authority
that CSW currently has with respect to those orders summarized in Exhibit I-4.
The Combined Company does not seek to widen such authority which will
necessarily remain limited to the orders described in Exhibit I-4. The practical
effect of this approval would be to insert the Combined Company alongside CSW in
virtually all instances where CSW is mentioned in such orders.

       Pursuant to Central and South West Corp., HCAR No. 26616 (Nov. 27, 1996),
this Commission confirmed previous authority and granted additional authority
such that CSW was authorized, through December 31, 2001, to offer 10,000,000
shares of CSW Common Stock pursuant to its Dividend Reinvestment and Stock
Purchase Plan, of which approximately 2,000,000 remain unissued. Pursuant to
American Elec. Power Co., HCAR No. 26553 (Aug. 13, 1996) this Commission
confirmed previous authority and granted additional authority such that AEP was
authorized, through December 31, 2000, to offer 54,000,000 shares of AEP Common
Stock pursuant to its Dividend Reinvestment and Direct Stock Purchase Plan.
Applicants hereby request that, as soon as practicable upon consummation of the
Merger, (1) the authority of CSW's Dividend Reinvestment and Stock Purchase Plan
be terminated, and (2) the Combined Company be authorized to issue 55,200,000
shares of AEP Common Stock through December 31, 2000 pursuant to its Dividend
Reinvestment and Direct Stock Purchase Plan consistent otherwise with all the
terms and conditions set forth in American Elec. Power Co., HCAR No. 26553 (Aug.
13, 1996).

       Pursuant to Central and South West Corp., HCAR No. 26413 (Nov. 21, 1995),
this Commission confirmed previous authority and granted additional authority
such that CSW was authorized to issue and sell a total of 5,000,000 shares of
CSW Common Stock to the trustee of the Central and South West Thrift Plan, of
which approximately 4,400,000 remain unissued. Pursuant to American Elec. Power
Co., HCAR No. 26786 (Dec. 1, 1997), this Commission confirmed previous authority
and granted additional authority such that AEP was authorized, through December
31, 2001, to sell 8,800,000 shares of AEP Common Stock to the trustee of the
American Electric Power System Employees Savings Plan. Applicants hereby request
that, upon consummation of the Merger, (1) the authority of CSW to issue shares
of CSW Common Stock to the Central and South West Thrift Plan be terminated, and
(2) the Combined Company be authorized to issue 11,440,000 shares of AEP Common
Stock through December 31, 2001 in connection with the American Electric Power
System Employees Savings Plan and the Central and South West Thrift Plan (for a
transitional period) consistent otherwise with all the terms and



                                                                              94
<PAGE>   95

conditions set forth in American Elec. Power Co., HCAR No. 26786 (Dec. 1, 1997)
and Central and South West Corp., HCAR No. 26413 (Nov. 21, 1995), respectively.

       Pursuant to Central and South West Corp., HCAR No. 25511 (Apr. 7, 1992),
this Commission authorized CSW to adopt the Central and South West Corporation
1992 Long Term Incentive Plan pursuant to which certain key employees would be
eligible, through December 31, 2001, to receive certain performance and
equity-based awards including (a) stock options, (b) stock appreciation rights,
(c) performance units, (d) phantom stock, and (e) restricted shares of common
stock. Applicants hereby request that, upon consummation of the Merger, the
Combined Company succeed to the authority of CSW to permit it (i) to honor the
awards granted by CSW prior to the consummation of the Merger, (ii) to
administer the plan (subject to any necessary shareholder or regulatory
approval) on a Combined Company basis and grant any remaining awards, and (iii)
to reserve and issue sufficient shares of AEP Common Stock pursuant to
subparagraphs (i) and (ii) above in connection with the Central and South West
Corporation 1992 Long Term Incentive Plan consistent otherwise with all the
terms and conditions set forth in Central and South West Corp., HCAR No. 25511
(Apr. 7, 1992).

       E.     SERVICE AGREEMENT; APPROVAL OF METHODOLOGY FOR ALLOCATING COSTS
              UNDER

       As described in Item 1.B.1 above, AEPSC is a service company that,
pursuant to service agreements with each of the subsidiary companies of AEP,
provides various technical, engineering, accounting, administrative, financial,
purchasing, computing, managerial, operational and legal services to each of the
AEP subsidiary companies. Pursuant to the service agreements, these services are
provided at cost. The Commission has previously determined that AEPSC is so
organized and its business is so conducted as to meet the requirements of
Section 13(b) of the 1935 Act and Rule 88 thereunder. Amer. Elec. Power Service
Corp., HCAR No. 21922 (Feb. 19, 1981) (order authorizing service agreement
between service company and operating subsidiaries).

       Similarly, CSWS is a service company which, pursuant to service
agreements signed with each of the subsidiary companies of CSW, provides various
technical, engineering, accounting, administrative, financial, purchasing,
computing, managerial, operational and legal services to each of the CSW
subsidiary companies. Pursuant to the service agreements, these services are
provided at cost. The Commission has also previously determined that CSWS is so
organized and its business is so conducted as to meet the requirements of
Section 13(b) of the 1935 Act and Rule 88 thereunder. Central and South West
Corp., HCAR No. 26293 (May 18, 1995).

       Upon consummation of the Merger, CSWS will be merged with AEPSC, and
AEPSC will be the surviving service company for the Combined System. Applicants
intend that AEPSC will enter into an amended service agreement with AEP's
subsidiary companies and CSW's subsidiary companies. The proposed amended
service agreement is filed as Exhibit B-2. Under the amended service agreement,
AEPSC will provide the managerial, administrative, financial, technical, and
other services previously provided by the two service companies, CSWS and AEPSC.
The execution and performance by the respective parties of the amended service
agreement is subject to Section 13(b) of the 1935 Act and the rules thereunder.
To the extent not exempt under rules or otherwise under the 1935 Act,
Applicants' subsidiaries will provide



                                                                              95
<PAGE>   96

services to each other at cost unless otherwise authorized by Commission orders.
See, e.g., Central and South West Corp., HCAR No. 26887 (June 19, 1998), AEP
Energy Services, Inc., HCAR No. 26267 (April 5, 1995) and AEP Resources, Inc.,
HCAR No. 26962 (Dec. 30, 1998) (authorizing certain non-regulated subsidiaries
of Applicants to provide services at fair market value).

       The amended service agreement to be entered into between AEPSC and the
utility and nonutility subsidiary companies of AEP and CSW, which, pending
Commission approval, will become effective upon the consummation of the Merger,
is similar to those service agreements currently in place. Under the terms of
the amended service agreement, AEPSC will render services to the subsidiary
companies of the Combined Company at cost. AEPSC will account for, allocate and
charge its costs of the services provided on a full cost reimbursement basis
under a work order system consistent with the Uniform System of Accounts for
Mutual and Subsidiary Service Companies. Costs incurred in connection with
services performed for a specific subsidiary company will be billed 100% to that
subsidiary company. Costs incurred in connection with services performed for two
or more subsidiary companies will be allocated in accordance with the
attribution bases set forth in Exhibit B-3. Indirect costs incurred by AEPSC
which are not directly allocable to one or more subsidiary companies will be
allocated in proportion to how either direct salaries or total costs are billed
to the subsidiary companies depending on the nature of the indirect costs
themselves. The time AEPSC employees spend working for each subsidiary will be
billed to and paid by the applicable subsidiary on a monthly basis, based upon
time records. Each subsidiary company will maintain separate financial records
and detailed supporting records showing AEPSC charges.

       Several state commissions have already approved the Merger and included
codes of conduct that will govern the relationship between AEPSC, the operating
companies, and other affiliated companies. For example, the orders of the
Indiana, Kentucky, Louisiana and Arkansas Commissions approving the Merger all
contain detailed guidelines relating to affiliate transactions. The order of the
Oklahoma Commission approving the Merger grants the Oklahoma Commission and the
State Attorney General access to the books and records of AEP and its affiliates
and subsidiaries (including their participation in joint ventures) with respect
to matters and activities that relate to Oklahoma retail rates. The settlement
with the staff of the Texas Commission requires compliance with a detailed code
of conduct governing activities among the Combined Company's subsidiaries. These
orders and agreements, consistent with state law, generally require certain
separations and safeguards between utility and nonutility affiliates to prevent
cross-subsidization and preferential treatment of nonutility affiliates.

       Applicants hereby request that the Commission approve the amended service
agreement between AEPSC and the subsidiary companies of the Combined Company and
the related attribution bases listed in Exhibit B-3. The proposed attribution
bases are based on cost-drivers emphasizing factors that correlate to the volume
of activity that is inherent in performing certain services. The frequency at
which each attribution basis will be recalculated is noted in Exhibit B-3.1.

       Exhibit B-3.2 compares the proposed attribution bases to the attribution
bases currently used by both AEPSC and CSWS. This exhibit also includes
explanations for the proposed differences. In all cases, the proposed
attribution bases are based on the attribution bases



                                                                              96
<PAGE>   97

currently used by either AEPSC or CSWS with some variations. Exhibit B-3.3
identifies the scope of each of the attribution bases by class of companies.
Exhibit B-3.4 describes the services that will be performed by AEPSC after the
Merger and lists the attribution bases associated with each major service
category.

       AEP currently utilizes the following principles in coordinating its work
order and billing control, planning and budgeting and internal audit functions
and expects that these principles will continue to govern such functions
following the Merger. An AEPSC work order may be initiated by AEPSC or by a
subsidiary company of AEP. Any AEPSC work order, whether for a single company or
multiple companies, including the proposed cost allocation method, must be
reviewed and approved by the AEPSC Corporate Accounting Department and then by a
person appointed by the subsidiary company. As a result of the centralization in
AEPSC of the responsibilities previously assigned to the officers of the
subsidiary companies, the Corporate Planning and Budgeting Department of AEPSC
has been appointed by the subsidiary companies to approve work orders. Corporate
Planning and Budgeting is independent of the AEPSC work order billing process,
which is maintained by the Corporate Accounting Department of AEPSC.

       Time records are completed by or for each employee in AEPSC and approved
by work group supervisors. Charges are accumulated by the Corporate Accounting
Department of AEPSC and billed to each AEP subsidiary company at the end of each
month. These bills are reviewed for reasonableness and approved on behalf of the
AEP subsidiary companies by Corporate Planning and Budgeting.

       Management has developed strategic performance measures for AEP and its
subsidiary companies as a business enterprise. These measures include earnings
per share, total shareholder return, competitive cost comparison, market share,
customer satisfaction and loyalty, employee development, safety and
productivity, and environmental performance. Management has developed targets
against which to measure the performance of AEP and its subsidiaries on a
consolidated basis. In addition, based upon these strategic performance measures
and targets, management has developed performance measures and targets for each
business group. These measures and targets focus on the business group, not on
the corporate entity; however, the expected impact of proposed plans and budgets
on expenses of the subsidiary companies is determined.

       Efficiency in business operations is important in order to achieve
targets in some of the strategic performance measures, such as earnings per
share and competitive cost comparison. A new planning and budgeting system,
including activity based management, has been developed and implemented. This
system focuses on the business process - a network of related and interdependent
activities performed to achieve a specific purpose. It provides cost information
quickly and allows managers to evaluate the efficiency and value of processes,
including trends and internal benchmarks.

       Using this planning and budgeting system, an annual budget is prepared by
each business unit and support organization and submitted to the Office of the
Chairman for approval. The Office of the Chairman consists of the Chairman of
the Board, President and Chief Executive Officer of AEP and AEPSC and the
executive vice presidents of AEPSC that report to him. A majority of these
officers are also directors and executive officers of each of the subsidiary



                                                                              97
<PAGE>   98

companies. The Corporate Planning and Budgeting Group assists the business units
and support organizations in the planning and budgeting process and monitors
expenses. It also determines and reports the expected impact of proposed plans
and budgets on the expenses of the subsidiary companies.

       The planning and budgeting process for AEPSC is part of the overall
process for the business units and support organizations and subject to approval
by the Office of the Chairman.

       The AEPSC Internal Audits Department continuously conducts audits of the
functions of AEP and its subsidiaries, including those of AEPSC, to ensure that
proper internal controls exist and to determine if they are functioning as
intended and are efficient and effective. As a part of the audit plan, the
Internal Audits Department performs audits of the AEPSC work order system and
related billings to AEP subsidiary companies. The purpose of the audits is to
render an opinion on the internal controls over the work order billing process
and compliance with Commission-approved cost allocation billing methodologies.
The Internal Audits Department completed the latest review in 1997 and expressed
an opinion that the internal controls are functioning properly and that the
costs are being allocated to AEP subsidiary companies in accordance with the
Commission-approved cost allocation billing methodologies. The Department will
perform its next audit of the work order system and related billings in 1999 and
then every two years.

       The Vice President of Internal Audits (the "Vice President") reports to
the Chairman of the Audit Committee of the Board of Directors of AEP (the "Audit
Committee"). Administratively, the Vice President reports to the Executive Vice
President - Financial Services of AEPSC. The Vice President attends each meeting
of the Audit Committee. In accordance with New York Stock Exchange listing
requirements, the Audit Committee is comprised solely of outside directors.

       In December of each year, the results of the year's audit activities are
reviewed with the Audit Committee and the following year's audit plan is
reviewed and approved by the Audit Committee. The Audit Committee annually
reviews and approves the Internal Audits Department Charter to ensure that it
sufficiently allows the Vice President to carry out his duties. The Vice
President meets privately with the Audit Committee several times during the year
and has the addresses and telephone numbers of the Audit Committee members and
is free to contact them at any time. The Vice President is reminded in these
private meeting sessions that he has such freedom.

       F.     ACQUISITION OF NON-UTILITY BUSINESSES

       Section 10(c)(1) provides that the Commission shall not approve an
acquisition that is "detrimental to the carrying out of the provisions of
Section 11." Section 11(b)(1) limits the non-utility interests of a registered
holding company to those that are "reasonably incidental, or economically
necessary or appropriate to the operations of such integrated public-utility
system." The Commission may find that a non-utility business meets this standard
when it finds that the interest in the business is "necessary or appropriate in
the public interest or for the protection of investors or consumers and not
detrimental to the proper functioning of such [integrated] system." CSW has a
number of non-utility businesses that AEP will indirectly acquire as a result




                                       98
<PAGE>   99

of the Merger. CSW owns seven material non-utility subsidiaries: CSW Energy, CSW
International, C3 Communications, EnerShop, CSW Energy Services, CSW Credit, and
holds an 80% interest in CSW Leasing. For a description of CSW's non-utility
businesses, see Item 1.B.1(b) supra. The Commission has found that CSW's
non-utility businesses meet the 11(b)(1) standard (to the extent that such a
finding was necessary).(35) Such businesses have an operating or functional
relationship to CSW's utility operations. See, e.g., Conectiv, supra (the
Commission has interpreted section 11(b)(1) "to require the existence of an
operating or functional relationship between the utility operations of the
registered holding company and its nonutility activities.")

       Upon consummation of the Merger, the non-utility businesses of CSW will
become indirect subsidiaries of AEP. To the extent that Commission approval is
necessary for the acquisition of CSW's non-utility businesses, the acquisitions
should be approved because the indirect ownership of CSW's non-utility
businesses by AEP in no way affects the functional relationship of these
businesses to the Combined Company's core electric business following the
Merger. Moreover, acquisition of these businesses is in the public interest and
consistent with the applicable standards under the 1935 Act.

       G.     ORGANIZATION OF MERGER SUB; ACQUISITION OF MERGER SUB COMMON STOCK

       Merger Sub was organized solely for the purpose of effecting the Merger
and has not conducted any activities other than in connection with the Merger.
Merger Sub has no subsidiaries. Each share of common stock of Merger Sub, par
value $0.01 per share, to be issued to AEP and outstanding immediately before
the consummation of the Merger will be converted into one share of CSW Common
Stock upon consummation of the Merger. Thus, the sole purpose for Merger Sub is
to serve as an acquisition subsidiary of AEP for purposes of effecting the
Merger. Approval of this Application-Declaration will constitute approval of the
acquisition by AEP of the common stock of Merger Sub.


ITEM 4.     REGULATORY APPROVAL

Set forth below is a summary of the material regulatory requirements affecting
the Merger. Failure to obtain any necessary regulatory approval or any adverse
conditions that are imposed in connection with any necessary regulatory
approval, including the failure to obtain appropriate ratemaking treatment, may
affect the consummation of the Merger.

- ---------------

            (35) A registered holding company may acquire and hold an interest
in an EWG, FUCO, and an exempt telecommunications company, without the need to
apply for or receive approval from the Commission (although the Commission
retains jurisdiction over certain related transactions with these entities).
Sections 32, 33 and 34 of the 1935 Act. Moreover, a registered holding company
may acquire "energy-related" companies meeting the Rule 58 safe harbor
conditions (including an investment ceiling) without the need for Commission
approval.


                                                                              99
<PAGE>   100

In addition to required Commission approvals, the state utility commissions of
Arkansas, Louisiana, Oklahoma, and Texas, and the FERC, the FCC, and the NRC
have jurisdiction over various aspects of the transactions proposed herein.(36)
Further, both AEP and CSW are required to file notification and report forms
under the HSR Act with the DOJ with respect to the Merger. Additional consents
from or notifications to governmental agencies may be necessary or appropriate
in connection with the Merger.

Applicants already have obtained regulatory approvals of the Nuclear Regulatory
Commission, the Arkansas Commission, the Oklahoma Commission, the Louisiana
Commission, the Kentucky Commission, and the Indiana Commission. A settlement
has been reached with FERC trial staff which resolves most issues, including
issues related to rates and competition. A stipulated settlement with the
commission staff and key intervenor groups has been reached in the Texas
proceeding, and Applicants anticipate that the FERC and the remaining state
commissions asserting jurisdiction over the Merger will make similar public
interest findings and issue orders approving the Merger in the near future.

       A.     ANTITRUST CONSIDERATIONS

       The HSR Act and the rules and regulations thereunder provide that certain
transactions (including the Merger) may not be consummated until certain
information has been submitted to the Antitrust Division and the specified HSR
Act waiting period has expired or been terminated. Applicants filed their
respective pre-merger notification pursuant to the HSR Act in July 1999. The
expiration or earlier termination of the HSR Act waiting period would not
permanently preclude the Antitrust Division from challenging the Merger on
antitrust grounds, but it would represent a decision by such agencies that the
Merger may be consummated without challenge under Section 7 of the Clayton Act.
If the Merger is not consummated within 12 months after the expiration or
earlier termination of the initial HSR Act waiting period, AEP and CSW must
submit new information to the Antitrust Division, and a new HSR Act waiting
period must expire or be earlier terminated before the Merger may be
consummated.

       B.     ATOMIC ENERGY ACT

       CSW, through its wholly-owned subsidiary CPL, owns a 25.2% interest in
the STP, a two-unit nuclear electric generating station. The STP is operated by
STP Operating, a Texas non-profit corporation, which is jointly-owned by CPL and
the other owners of the STP. CPL holds NRC licenses with respect to its
ownership interests in the STP and STP Operating. Section 184 of the Atomic
Energy Act provides that no license may be transferred, assigned or in any
manner disposed of, directly or indirectly, through transfer of control of any
license to any

- -----------------

            (36) AEP has U.S. electric utility subsidiaries operating in Ohio,
Indiana, Kentucky, Michigan, Tennessee, Virginia, and West Virginia. AEP
believes that the approval of the utility regulatory commissions in these states
is not required to consummate the Merger, and that these states therefore do not
have jurisdiction over this proposed transaction. Nevertheless, the Indiana
Commission and the Kentucky Commission have approved the Merger, and AEP has
been actively working with all of these state commissions regarding both the
FERC and state regulatory impacts of the transaction.


                                                                             100
<PAGE>   101

person, unless the NRC finds that the transfer is in accordance with the
provisions of the Atomic Energy Act and gives its consent in writing.

       On June 19, 1998, CPL sought approval from the NRC for the transfer of
control of its NRC licenses as a result of the Merger. The Application for
Transfers of Control Regarding Operating License No. NPF-76 and NPF-80 for the
STP is filed as Exhibit D-6.1. On November 5, 1998, the NRC approved the
transfer of control of CPL's NRC licenses. The NRC Order is filed as Exhibit
D-6.2, and incorporated by reference. After the Merger, CPL, as an operating
utility subsidiary of the Combined Company, will continue to own the identical
pre-Merger interests in the STP and STP Operating.

       C.     FEDERAL POWER ACT

       Section 203 of the FPA provides that no public utility may sell or
otherwise dispose of its jurisdictional facilities, directly or indirectly merge
or consolidate its facilities with those of any other person, or acquire any
security of any other public utility, without first having obtained
authorization from the FERC. On April 30, 1998, AEP and CSW filed a joint
application with the FERC seeking approval of the Merger, as supplemented on
January 13, 1999. See Exhibits D-1.1 and D-1.2. A procedural schedule has been
adopted by FERC which directs the Administrative Law Judge to issue an Initial
Decision no later than November 24, 1999. This schedule will allow FERC to issue
a decision no later than March 2000. Under Section 203 of the FPA, the FERC will
approve a merger if it finds the merger to be 'consistent with the public
interest.'

       On June 24, 1999, Applicants and the FERC trial staff filed the FERC
Stipulation resolving major issues related to the Merger, including all
significant competition and rate issues. In addition, FERC Trial Staff agreed to
support a finding that the Merger will have no adverse effect on competition.
The FERC Stipulation is filed as Exhibit D-1.3.

       Under the terms of the FERC Stipulation, prior to the consummation of the
Merger, AEP will file with the FERC a proposal whereby it would transfer certain
control area functions relating principally to reliability and access to an
RTO.(37) As part of the transfer, AEP agreed to transfer functions relating to
transmission service, transmission security and control area responsibility to
the RTO. In addition thereto, prior to December 31, 2000, AEP will file with the
FERC an unconditional application to transfer the corresponding control area
functions relating principally to reliability and access, controlled and/or
operated by AEP and currently located in the SPP to a FERC-approved RTO directly
interconnected with the facilities located outside the SPP.

       The FERC Stipulation also addresses rates for transmission services and
ancillary services and confirms, subject to FERC guidance on the timing of
divestiture, that the previously

- -------------

            (37) As noted in Item I.B.2.d. above, on June 3, 1999, AEP and four
other utilities filed the Alliance RTO Application. CSW is participating in the
ERCOT independent regional transmission plan for the portion of its system that
is within ERCOT and is participating in discussions with other interested
parties about the formation of an RTO that would include utility systems in the
SPP.



                                                                             101
<PAGE>   102

announced generation divestiture program will satisfy the market power concerns
of the FERC trial staff. In its filing with FERC, the Applicants proposed
divesting ownership of 300 MW of generation capacity at CSW's Northeastern Power
Station Units 3 and 4 and 250 MW of generation capacity located at the Frontera
Power Plant, a merchant power plant being constructed by a CSW subsidiary near
Mission, Texas.

       In addition to the waiver of transmission priorities that is explained in
the FERC testimony of Stephen B. Jones, Applicants agreed that they will not
assert the "AES/TVA" priority for any transfers of non-firm energy from AEP West
to AEP East for a period of four years from the date of the consummation of the
Merger.

       D.     COMMUNICATIONS ACT

       CSW, itself or through one or more subsidiaries, holds various radio
licenses subject to the jurisdiction of the FCC under Title III of the
Communications Act. Under Section 310 of the Communications Act, no station
license may be assigned or transferred, directly or indirectly, except upon
application to and approval by the FCC. On July 26, 1999, Applicants filed with
the FCC for authority to transfer control of licenses held by several CSW
subsidiaries to AEP. See Exhibit D-9.1.

       E.     ARKANSAS COMMISSION

       SWEPCO is subject to the jurisdiction of the Arkansas Commission.
Pursuant to Section 23-3-306(b) of the Arkansas Statutes, and Arkansas
Commission approval is required before any person may merge with or otherwise
acquire control of a domestic public utility. The Arkansas Commission must
approve a merger application unless it finds that one or more of five adverse
circumstances would result from the transaction. The circumstances include an
adverse effect on the public utility's existing obligations or quality of
service, a reduction in competition for the provision of utility services within
the state, and an adverse effect on the financial condition of the public
utility.

       On June 12, 1998, AEP, CSW and SWEPCO filed an application with the
Arkansas Commission seeking Arkansas Commission approval of the Merger, a copy
of which is filed as Exhibit D-2.1 and incorporated by reference. On August 13,
1998, the Arkansas Commission issued an order conditionally approving the
Merger, a copy of which is filed as Exhibit D-2.2 and incorporated by reference.

       F.     LOUISIANA COMMISSION

       SWEPCO is subject to the jurisdiction of the Louisiana Commission.
Pursuant to Louisiana Statutes Section 45:1164, the Louisiana Commission is
granted general supervisory authority over public utilities operating in the
state and, under this authority, the Louisiana Commission has held that its
approval or non-opposition is required prior to the sale, lease, merger,
consolidation, stock transfer, or any other change of control or ownership of a
public utility subject to its jurisdiction. The Louisiana Commission reviews
merger applications pursuant to an 18 factor test that generally relates to the
impact of the transaction on competition, the financial condition of the
utility, quality of service, public health and safety, employment, and other
similar "public interest" matters.

                                                                             102
<PAGE>   103

       On May 15, 1998, AEP, CSW and SWEPCO filed an application seeking
Louisiana Commission approval of, or non-opposition to, the Merger, a copy of
which is filed as Exhibit D-3.1 and incorporated by reference. On July 29, 1999,
the Louisiana Commission voted to issue an order conditionally approving the
Merger, a copy of which is filed as Exhibit D-3.2 and incorporated by reference.

       G.     OKLAHOMA COMMISSION

       PSO is subject to the jurisdiction of the Oklahoma Commission. The
Oklahoma Statutes concerning mergers and acquisitions of public utilities are
substantially identical to the sections of the Arkansas Statutes discussed
above. Oklahoma Commission approval is required before any person may merge with
or otherwise acquire control of an Oklahoma public utility.

       On August 14, 1998, AEP, CSW and PSO filed an application with the
Oklahoma Commission seeking approval of the Merger, a copy of which is filed as
Exhibit D-4.1 and incorporated by reference. On May 4, 1999, an administrative
law judge recommended that the Oklahoma Commission approve the Merger subject to
certain conditions. Those conditions included the recommendation that Applicants
participate in an SPP study of the impacts of the effect of the Merger on the
transmission system of OG&E at its Fort Smith, Arkansas substation. On May 11,
1999, the Oklahoma Commission issued an order conditionally approving the
Merger, a copy of which is filed as Exhibit D-4.2 and incorporated by reference.
The order of the Oklahoma Commission is currently the subject of an appeal.

       H.     TEXAS COMMISSION

       CPL, SWEPCO, and WTU are subject to the jurisdiction of the Texas
Commission. Pursuant to Section 14.101 of the Texas Utilities Code, each
transaction involving the sale of at least 50 percent of the stock of a public
utility must be reported to the Texas Commission within a reasonable time. On
April 30, 1998, AEP, CSW, CPL, SWEPCO and WTU reported the Merger to the Texas
Commission for its review, as supplemented on January 15, 1999. See Exhibits
D-5.1 and D-5.2.

       In reviewing a transaction involving the sale of at least 50 percent of
the stock of a Texas utility, the Texas Commission is required to determine
whether the action is consistent with the public interest, taking into
consideration factors such as the reasonable value of the property, facilities,
or securities to be acquired, disposed of, merged, transferred, or consolidated,
and whether the transaction will adversely affect the health or safety of
customers or employees, result in the transfer of jobs of Texas citizens to
workers domiciled outside of Texas, or result in the decline of service. If the
Texas Commission determines that a transaction is not in the public interest, it
may take the effect of the transaction into consideration in ratemaking
proceedings and disallow the effect of such transaction if such transaction will
unreasonably affect rates or service.

       In the proceedings before the Texas Commission, Applicants reached a
settlement with the Public Utility Commission of Texas General Counsel, the
State of Texas (in its capacity as a consumer of electricity), the Texas
Industrial Energy Consumers, Low Income Intervenors, the Office of Public
Utility Counsel, and the Steering Committee of the Cities of McAllen, Corpus



                                                                             103
<PAGE>   104

Christi, Victoria, Abilene, Big Lake, Vernon and Paducah. The Texas Stipulation
is filed as Exhibit D-5.3 and incorporated by reference. In addition thereto, in
a letter dated July 9, 1999 to the administrative law judge in the Texas
proceeding, Medina Electric Cooperative, Inc. and the City of Robstown, Texas
stated that they have no objection to the Merger and will not file testimony in
that proceeding. Furthermore, agreements have been reached with several
wholesale customer groups including South Texas Electric Cooperative (STEC) and
its member distribution cooperatives, the City of Brownsville Public Utility
Board, the East Texas Cooperatives, which includes East Texas Electric
Cooperative Inc., Northeast Texas Electric Cooperative, Inc., and Tex-La

       K.     MISSOURI COMMISSION

       No regulatory authorization is required from the Missouri Commission.
However, in an effort to address concerns raised by the Missouri Commission with
respect to competitive impacts that may occur as a result of Applicants' use of
the Contract Path, Applicants agreed that, as part of a settlement between
Applicants and the Missouri Commission, the Missouri Commission may initiate,
within four years of the consummation of the Merger, a review by the FERC of the
Merger's effects on retail competition, assuming retail competition has been
implemented in Missouri. The settlement also gives the FERC discretion to decide
if mitigation measures are necessary to the extent that the review results in a
finding that the Contract Path is harmful to competition. Any relief ordered by
FERC cannot extend beyond six years after the consummation of the Merger.

       L.     AFFILIATE CONTRACTS

       AEP, CSW and their subsidiaries intend to enter into or amend agreements
related to the provision by affiliates of various services, including
management, supervisory, construction, engineering, accounting, legal, financial
or similar services. The approval or non-opposition of certain state regulatory
commissions and the Commission is required with respect to the creation or
amendment of certain inter-affiliate agreements. Applicants and their
subsidiaries intend to file such agreements with the appropriate state
regulatory commissions within the next few months.




                                                                             104

ITEM 7.     INFORMATION AS TO ENVIRONMENTAL EFFECTS

       The Merger neither involves "major federal actions" nor "significantly
[affects] the quality of the human environment" as those terms are used in
Section (2)(C) of the National Environmental Policy Act, 42 U.S.C. Sec. 4332.
The only federal actions related to the Merger pertain to the Commission's
declaration of the effectiveness of the Registration Statement, the approvals
and actions described under Item 4 and Commission approval of this
Application-Declaration. Consummation of the Merger will not result in
significant changes in the operations of public utilities of the AEP or CSW
Systems or have any significant impact on the environment. Apart from the
Application for Transfers of Control Regarding Operating License No. NPF-76 and

                            UNITED STATES OF AMERICA
                                   BEFORE THE

              STIPULATION OF AMERICAN ELECTRIC POWER COMPANY, INC.
                     CENTRAL AND SOUTH WEST CORPORATION AND
                             COMMISSION TRIAL STAFF

     For the purposes of evaluating the justness and reasonableness of the
System Integration Agreement, the Transmission Reassignment Tariff and the
System Transmission Integration Agreement proposed by American Electric Power
Company, Inc. ("AEP") and Central and South West Corporation
("CSW")(collectively "Applicants"), the Applicants and the Trial Staff hereby
enter into this Stipulation. This Stipulation resolves all issues between
Applicants and the Trial Staff regarding the System Integration Agreement, the
Transmission Reassignment Tariff and the System Transmission Integration
Agreement in the above-referenced consolidated dockets ("this proceeding"),
except the pricing of system energy exchanges under the System Integration
Agreement. Applicants and the Trial Staff stipulate and agree as follows:

I.   SYSTEM INTEGRATION AGREEMENT (SIA)

     A.   ARTICLE 7.3 OF THE SYSTEM INTEGRATION AGREEMENT WILL BE MODIFIED TO
          READ AS FOLLOWS:

          Whenever either the AEP East Zone or the AEP West Zone has surplus
          capacity relative to is capacity planning reserve requirements or
          otherwise has capacity available for sale, and the other zone has
          insufficient capacity relative to its capacity planning reserve
          requirements, the surplus zone, acting through the Agent, shall make
          its surplus capacity available to the other zone for periods of one
          (1) year or less, subject to the Interconnection Constraints. Such
          capacity exchanges shall only be made when the selling region's
          foregone opportunity cost to sell capacity is lower than the buying
          region's decremental capacity purchase cost.
<PAGE>   2
     B.   THE FOLLOWING DEFINITIONS WILL BE ADDED TO THE SYSTEM INTEGRATION
          AGREEMENT:

          Foregone Opportunity cost as it relates to capacity exchanges means
          what the supplier could have sold the capacity for in its own zonal
          market if the capacity exchange did not take place, i.e., Market
          Price. The determination of Market Price shall be based on actual
          sales of similar characteristics to unaffiliated third parties. In the
          event that no such sales are available, documentable offers from
          unaffiliated third parties shall determine the Market Price. In the
          event that no such offers are available, a published index of capacity
          market price shall determine the Market Price.

          Decremental Capacity Cost in the recipient zone means the lower of the
          recipient's cost of capacity installation or capacity purchase price
          in its own zonal market, i.e., Market Price. The determination of
          Market Price shall be based on actual purchases of similar
          characteristics from unaffiliated third parties. In the event that no
          such purchases are available, documentable offers from unaffiliated
          third parties shall determine the Market Price. In the event that no
          such offers are available, a published index of capacity market price
          shall determine the Market Price.

          Owned General Capacity is the aggregate capacity of the electric power
          sources of the zone, in Kilowatts, that is normally expected to be
          available to carry load. Such capacity shall include (i) the capacity
          installed at the generating stations owned by the operating companies
          in the zone and (ii) the capacity available to the operating companies
          of the zone through arrangements with affiliated companies or
          unaffiliated companies, if so designated by the Operating Committee
          with the approval of the operating companies.

     C.   THE FOLLOWING PROVISION WILL BE ADDED TO THE TEXT AT THE END OF
          PARAGRAPH A2 OF SERVICE SCHEDULE A:

          At such time as the Agent determines an allocation among the operating
          companies of new capacity that AEP has constructed or purchased, AEP
          will convey its decision respecting such allocation to its wholesale
          customers buying at a cost-of-service rate and each state regulatory
          commission with jurisdiction over the operating companies. Each such
          customer buying at a cost-of-service rate and each state regulatory
          commission shall retain any right provided them under the Federal
          Power Act to challenge AEP's decision.

     D.   ALLOCATION OF TRADING MARKET REALIZATIONS

          Add as the last two sentences to Service Schedule D, Paragraph D3 --
          Allocation of Trading and Marketing Realizations, the following
          language: "This allocation of trading market realization shall be in
          effect until the last day of the fifth full calendar year following
          the consummation of the merger. At least sixty days prior to the day
          specified in the preceding sentence, Agent shall file with the


                                      -2-
<PAGE>   3
          FERC under Section 205 of the Federal Power Act the methodology to
          allocate trading market realizations thereafter, supported by evidence
          demonstrating the justness and reasonableness of the filed
          methodology."

     E.   PRICING OF SYSTEM ENERGY EXCHANGES

          Applicants and Trial Staff agree that the issue of pricing for system
energy exchanges pursuant to Service Schedule C would be most efficiently
addressed as a policy issue briefed directly to the Commission. Accordingly, it
is the intention of Applicants and Trial Staff that each will present their
position on this aspect of the System Integration Agreement directly to the
Commission for resolution and that the issue need not be addressed by the
Presiding Judge.

II.  TRANSMISSION REASSIGNMENT TARIFF (TRT)

     A.   TERMINATION PROVISIONS

     The words "in accordance with Commission regulations" will be added after
the word "Agreement" in the first line of Section 3.3 of the Form of Service
Agreement.

     B.   REFUNDS FOR RECALLED TRANSMISSION CAPACITY

     Article III.D. shall be modified to include the following sentence at the
     end:

     The availability of refunds for service sold under this Transmission
     Reassignment Tariff shall be covered in the Service Agreement, or, for
     short-term transactions, in the umbrella Service Agreement, between AEP and
     the Eligible Customer purchasing the reassigned transmission capacity.

     C.   EFFECT OF TARIFF TERMINATION

     Amend Section IV.C of the Transmission Reassignment Tariff by adding this
sentence to the end: "A notice of termination of this tariff by Reseller shall
1) terminate Reseller's obligation to provide service under any new Service
Agreement or provide new transactions under an umbrella Service Agreement
immediately and 2) eliminate all tariff obligations at the time that the last
remaining service arrangement initiated prior to the notice of termination is
completed."

III. SYSTEM TRANSMISSION INTEGRATION AGREEMENT (STIA)

     The following sentence from Part A2 of Service Schedule A in the System
Transmission Integration Agreement,

          When new Transmission Facilities are acquired or installed after the
          effective date of the Agreement to meet the Combined System's
          requirements, the associated costs shall be allocated between the AEP
          East Zone and AEP West Zone in



                                      -3-
<PAGE>   4
          proportion to the amount of new Transmission Facilities required in
          each zone, as determined by the Agent.

will be deleted and replaced by:

          Likewise, the operating companies in the AEP East Zone and the
     operating companies in the AEP West Zone each shall have full
     responsibility for all costs relating to new Transmission Facilities they
     may acquire or install in their respective zones after the effective date
     of the Agreement which do not create a direct linkage between the AEP East
     and West Zones. When new Transmission Facilities are acquired or installed
     after the effective date of the Agreement to further integrate the AEP East
     and West Zones, the associated costs shall be allocated equally between the
     AEP East Zone and AEP West Zone.

IV.  GENERAL PROVISIONS

     Applicants and the Trial Staff shall support this Stipulation in all
proceedings before this Commission, and based on this Stipulation, Applicants
and the Trial Staff shall support a finding that the above-mentioned
agreements, as modified by this stipulation, are just and reasonable.
Applicants and the Trial Staff further agree that neither will challenge any
presentation by a signatory to this stipulation with respect to the matters at
issue in this proceeding, so long as such presentation is in accord with this
Stipulation, and that each will support this Stipulation as a resolution of the
matters addressed herein as consistent with the requirements of the Federal
Power Act. Each party shall be free to argue, in response to challenges by
other parties, that this Stipulation is justified as a compromise of more
favorable positions or principles that such party supported, but neither party
may ask the Commission to vary from this Stipulation for purpose of this
proceeding.

     This Stipulation is not intended to bind any party that is not a signatory
hereto, and is not intended to set a precedent for future cases or to bind any
party in any further proceeding with respect to any matter set forth herein. No
term in this Stipulation may be modified without the express written consent of
all signatories.

                  STIPULATION OF AMERICAN POWER COMPANY, INC.,
                       CENTRAL AND SOUTH WEST CORPORATION
                           AND COMMISSION TRIAL STAFF

     For the purposes of evaluating the consistency of the merger proposed by
American Electric Power Company, Inc. ("AEP") and Central and South West
Corporation ("CSW")(collectively "Applicants") with the public interest and for
evaluating the rates proposed by the Applicants for transmission and ancillary
services for post merger operations, Applicants and the Trial Staff hereby enter
into this Stipulation. This Stipulation resolves all issues between Applicants
and the Trial Staff regarding the matters set for hearing in the
above-referenced consolidated dockets ("this proceeding") except for the issues
pertaining to system integration agreements and ratepayer protection. In
addition, a question related to the timing of divestiture will be resolved by
direct presentation to the Commission, as described below.

     Applicants and the Trial Staff stipulate and agree as follows:

I.   RATES

     The rates identified in Attachment A to this Stipulation shall be placed
into effect as of the date on which the merger is consummated. Notwithstanding
the foregoing, the Applicants shall have the right to tender for filing pursuant
to section 205 of the Federal Power Act changes in any or all of
<PAGE>   6
the rates identified in Attachment A and to seek an effective date on or after
the date on which the merger is consummated.

II.  REGIONAL TRANSMISSION ORGANIZATION

     A.   Prior to consummation of the merger AEP will file with the Federal
          Energy Regulatory Commission ("FERC") a proposal to transfer to a
          regional transmission organization ("RTO") the operation and control
          of bulk transmission facilities owned, controlled, and/or operated by
          AEP in Indiana, Michigan, Kentucky, Ohio, Tennessee, Virginia and
          West Virginia ("AEP East"). In addition, Applicants reconfirm the
          commitments made in paragraph 7A of the Stipulation and Agreement
          attached to the order of the Indiana Utility Regulatory Commission
          dated April 26, 1999 in Cause No. 41210, which paragraph is reproduced
          in Attachment B to this Stipulation and incorporated herein.

     B.   Prior to December 31, 2000, AEP will file with the FERC an
          unconditional application to transfer the operation and control of
          bulk transmission facilities owned, controlled and/or operated by AEP
          and currently located in the Southwest Power Pool ("AEP West") to a
          FERC-approved RTO directly interconnected with the AEP West
          transmission facilities. Such transfer of operations shall be
          consistent with the applicable RTO. The above date shall be extended,
          if necessary, to 75 days after FERC issues an order on an RTO to which
          AEP is a signatory that is filed before June 30, 2000.

     C.   If AEP meets its commitments pursuant to provision A in a manner other
          than joining the Midwest ISO, the provisions of the following
          paragraphs C.1., C.2., C.3. shall
<PAGE>   7
apply. If AEP meets its commitments pursuant to provision A by joining the
Midwest ISO, then only paragraph C.2. shall apply.

1.   For AEP East, AEP will provide generation dispatch information necessary
     for the Midwest ISO to monitor the effect of such dispatch on the loading
     of the Midwest ISO's constrained transmission facilities. The Midwest ISO,
     in consultation with AEP, shall determine the format, quantity, and timing
     of the data submissions necessary to perform such monitoring. The
     information provided by AEP shall be subject to appropriate confidentiality
     provisions. AEP's obligation to submit such data shall be effective at such
     time as the Midwest ISO has procedures in place to assure that there is no
     disclosure of company-specific information or contemporaneous data.

2.   For AEP East, AEP agrees to transfer functions relating to transmission
     service, transmission security and control area responsibility, as
     described in Attachment C, to the FERC-approved RTO to which it transfers
     operation and control of its bulk transmission facilities pursuant to
     provision A. AEP will transfer these functions by leasing and/or selling
     the present AEP System Control Center ("SCC") site and facilities to the
     RTO, and providing the present SCC employees the opportunity to transfer to
     the RTO with all the financial conditions necessary to create independence
     from AEP. AEP's transfer of such functions shall be conditional on:


     a)   the RTO, in consultation with AEP, determining that the RTO has the
          capability to accept responsibility for these functions;

<PAGE>   8
     b)   systems being in place for AEP to retain economic dispatch and
          automatic general control ("AGC") functions and allow separation for
          wholesale transaction billing;

     c)   the RTO, in consultation with AEP, developing guidelines and
          procedures whereby the Area Control Error ("ACE") values calculated
          and communicated by the RTO to AEP are combined with AEP's own
          economic dispatch values to permit AEP to directly pulse its
          generating units under AGC; and

     d)   transmission functions other than those listed in Attachment C to this
          Stipulation being transferred to other AEP regional facilities.

3.   AEP commits to participate in ancillary services and balancing markets
     developed by the RTO or an RTO-authorized Regional Power Exchange. AEP will
     bid to redispatch generators consistent with bidding requirements
     established by the RTO for all parties that control the dispatch of
     generating facilities taking service from the RTO.

<PAGE>   9
III.   INTERIM TRANSMISSION PROVISION

       A.  It is AEP's position that it currently is, and at all times has been,
           in compliance with all applicable requirements with respect to the
           provision of transmission service, including its open access
           transmission tariff. AEP's agreement to the following conditions
           shall not be construed as evidence of or an admission that its
           current or historical practices are or have been in violation of any
           such applicable requirement.

           1.   AEP will file for a declaratory order that its "flexible
                point-to-point" service is permitted under AEP's Open Access
                Tariff or other transmission service agreements on file with the
                Commission.

           2.   AEP will post on OASIS the status of all AEP East transmission
                facilities, including planned maintenance, for the period of the
                ATC postings.

       B.  AEP will follow ECAR Security Coordinator procedures for posting
           transmission loading relief ("TLR") logs.

IV.    DIVESTITURE

       Applicants and Trail Staff agree that the Applicants will divest the
Frontera and Northeastern Units 3 and 4 as proposed in the testimony of Witness
Stephen B. Jones, with a buy-back condition and the presentation of one reserved
issue. The divestiture requirement must not infringe upon AEP-West's ability to
serve native load. The divestiture proposal should include a buy-back clause
such that AEP West can purchase the firm power it needs to serve native load.

<PAGE>   10
       The reserved issue will be presented directly to the Commission for
decision based on the comments on this settlement submitted by the participants
in this proceeding. Specifically, the Commission's Trial Staff, the Applicants,
and other parties shall have the right to address in comments whether the
Commission should order an immediate divestiture of these facilities or whether
the divestiture should occur under both the conditions stated in Witness Jones'
testimony and the additional conditions incorporated in the stipulation entered
into in the proceeding before the Oklahoma Corporation Commission, Cause No.
PUD 980000444, dated April 16, 1999 and attached as Attachment D to this
Stipulation. These additional conditions are contained in Section 7, third
paragraph of the stipulation and require an informational filing before the
Oklahoma Corporation Commission should the conditions proposed by the Applicants
in this FERC proceeding be changed.

       Trial Staff and the Applicants agree that the question of whether
immediate divestiture should be required should be presented to the Commission
in light of two questions. The first question is whether it is appropriate to
permit the timing of the divestiture to occur so as to assure that pooling of
interests accounting not be jeopardized. The second question is whether a
change in the timing for the divestiture for Northeastern Units 3 and 4 is
consistent with the deference that the Commission should provide to the Oklahoma
Corporation Commission's determination as to the conditions necessary to protect
the interests of Applicants' Oklahoma retail customers. Trial Staff and
Applicants further agree to limit their comments in support of their position on
this reserved issue to the two questions stated in this paragraph. Applicants
reserve the right to address other arguments raised in the comments of other
parties that assert other bases to accelerate the timing of the divestiture of
the Frontera and Northeastern Units 3 and 4.



<PAGE>   11
     Applicants agree that the conditions of sale for Northeastern Units 3 and
4 will provide that the purchaser(s) of the units shall be guaranteed that
planned (maintenance) outage schedules shall be made only with the mutual
consent of the merged company and the purchaser(s).

V. APPLICANTS' WAIVER OF TRANSMISSION PRIORITY

     In addition to the waiver of transmission priorities otherwise available
to Applicants that is contained in the testimony of Witness Stephen B. Jones,
Applicants further agree that they will not assert the "AES/TVA" priority for
any transfers of energy from AEP West to AEP East for a period of four years
from the date of the consummation of the merger.

VI.  LOSSES AND LOSS COMPENSATION SERVICE

     A. The Real Power Loss Factor stated in Sections 15.7 and 28.5 of the post
        merger AEP open access transmission tariff ("Tariff") shall be 3.3% for
        AEP East and shall be  2.9% for AEP West.

     B. The following sentence shall be added after the second sentence of
        SCHEDULE 20 of the Tariff regarding Loss Compensation Service: "Charges
        for Loss Compensation Service shall be pursuant to rates negotiated
        between the Transmission Customer and the Transmission Provider."

     C. The following sentence shall be added after the first sentence of
        SCHEDULES 7 and 8 of the Tariff regarding Firm and Non-Firm
        Point-to-Point Transmission Service: "Capacity Reservations at the
        Point(s) of Receipt will be inclusive of transmission losses, unless the
        Transmission Customer opts to deliver energy to compensate for losses at
        a different point pursuant to another capacity reservation."
<PAGE>   12
VII. GENERAL PROVISIONS

     Applicants and Trial Staff shall support this Stipulation in all
proceedings before this Commission, and based on this Stipulation, Trial Staff
shall support a finding that the merger will have no adverse effect on
competition. Applicants and the Trial Staff further agree that neither will
challenge the other party's presentation with respect to the matters at issue
in this proceeding, so long as such presentation is in accord with this
Stipulation, and that each will support this Stipulation as a resolution of the
matters addressed herein as consistent with the requirements of the Federal
Power Act. Each party shall be free to argue, in response to challenges by
other parties, that this Stipulation is justified as a compromise of more
favorable positions or principles that such party supported, but neither party
may ask the Commission to vary from this Stipulation for purpose of this
proceeding.

     This Stipulation is not intended to bind any party that is not a signatory
hereto, and is not intended to set a precedent for future cases or to bind any
party in any further proceeding with respect to any matter set forth herein. No
term in this Stipulation may be modified without the express written consent of
both parties.

7.   REGIONAL TRANSMISSION ORGANIZATION.

     A.   Prior to December 31, 2000, AEP will file with the FERC an
          unconditional application, consistent with the RTO agreement and
          tariff to transfer the operation and control of its bulk transmission
          facilities in Indiana, Michigan, Kentucky, Ohio, Tennessee, Virginia
          and West Virginia owned, controlled and/or operated by AEP to the
          Midwest Independent Transmission System Operator, Inc. or another
          FERC-approved Regional Transmission Organization directly
          interconnected with AEP transmission facilities. Provided that, if, by
          June 30, 2000, there is pending before the FERC for approval an RTO to
          which AEP is a signatory that includes two or more directly
          interconnected control areas, at least one of which is not affiliated
          with AEP, the December 31, 2000 date shall be extended to the date
          that is 75 days after the date on which the FERC issues an order
          either approving or disapproving the RTO.

 1. TRANSMISSION SERVICE FUNCTIONS

    A. The RTO will administer AEP's Open Access Transmission Tariff and any
       succeeding RTO Tariff as follows:


       1. When the RTO, in consultation with AEP, determines that it is capable
          of centrally calculating ATCs on data partially or totally developed
          by the RTO it will calculate and post ATCs on OASIS.

       2. The RTO will assume responsibility for transmission service contracts.

       3. When the RTO determines, in consultation with AEP, that it is capable
          of performing the function, the RTO will manage the single OASIS site
          for the AEP System.

          4. When the RTO determines, in consultation with AEP, that it is
             capable of performing the function, it will have the sole authority
             to receive, evaluate, and approve or deny all transmission service
             requests on the AEP System.

          5. The RTO will offer to provide losses and ancillary services and
             verify customer self-provision of such services.

          6. The RTO will perform settlement/billing for transmission service
             and ancillary services.

    B. The RTO will return revenues to AEP, and/or allocate revenue to AEP and
       other RTO transmission owners, as applicable.

II. TRANSMISSION SECURITY FUNCTIONS

    A. The RTO will perform the role of NERC Security Coordinator.
<PAGE>   18
      B. The RTO will perform congestion management.

      C. The RTO will approve transmission maintenance requests and outages.

III. CONTROL AREA FUNCTIONS

      A. When the RTO, in consultation with AEP, determines that it is capable
         of performing the function, the RTO will be the single entity with
         responsibility to schedule energy transactions over approved
         transmission reservation paths.

      B. The RTO will coordinate and participate in time corrections.

      C. The RTO will assure the maintenance of NERC/ECAR operating reserves.

      D. The RTO will maintain load-generator balances (Control Area
         Regulation) by sending ACE signals to generating companies or
         independent generators that have contracted to provide regulation.

      E. The RTO will perform check out (after-the-fact) of energy MWH
         transactions with other control areas, and perform inadvertent
         accounting.

SECTION 7. MITIGATION.

     To mitigate any perceived impacts of the merger on the Applicants' market
power, the Applicants have proposed in their FERC merger application a
mitigation plan which includes the following:

          (1) Divestiture of 300 megawatts of coal-fired generating capacity at
              the Northeastern generating plant after such plant is no longer
              required to meet PSO's native load demand requirements subsequent
              to industry restructuring in Oklahoma.

          (2) Sale of 300 megawatts per hour of energy on an interim basis
              prior to the divestiture of the Northeastern capacity.

          (3) Waiver of PSO's priority to the use of CSW interfaces with other
              transmission systems to import centrally dispatched energy from
              the existing AEP system in excess of 250 megawatts.

          (4) Waiver of PSO's priority to the use of CSW interfaces to import
              non-firm energy from non-affiliates.

          (5) Schedule CSW's use of the two high voltage direct current (HVDC)
              ties between ERCOT and the SPP on a first-in-time basis for
              certain transactions.

          The Applicants commit to hold PSO Oklahoma retail customers harmless
from adverse impacts from these transactions. Attachment 4 to this agreement
describes the methodology that the Applicants will follow in order to hold PSO
Oklahoma retail customers harmless from adverse effects of the interim
mitigation sale.

         On June 12, 1998, the Commission issued Order No. 1 in this docket
establishing a procedural schedule, with a hearing date of July 13, 1998. On
June 26, 1998, Applicants and the General Staff of the Commission ("Staff")
filed their Joint Motion to Defer Consideration of the Regulatory Plan and to
Establish a Procedural Schedule. The Commission granted the joint motion by its
Order No. 4, dated July 1, 1998. The procedural schedule was subsequently
amended by Order No. 7, dated September 9, 1998.

         On August 13, 1998, the Commission issued its Order No. 5, approving
the merger subject to certain conditions, including the Commission's findings
and orders with respect to the PRP. Order No. 6, dated August 19, 1998,
corrected certain errors in Order No. 5.

         In accordance with the procedural schedule established in Order No. 7,
Staff filed on October 23, 1998, the Testimony and Exhibits of Alice D. Wright,
J. Bret Franks, and Mark Witkowski addressing certain aspects of the PRP. On
November 3, 1998, Applicants and Staff filed a Regulatory Plan Stipulation and
Agreement ("RSPA") executed by Applicants and Staff and a Joint Motion to Accept
the Regulatory Plan Stipulation and Agreement and to Cancel the Remaining
Testimony Filing Dates. On November 4, 1998, Order No. 8 canceled the remaining
testimony filing dates and directed that the RSPA be considered at the public
hearing previously scheduled for December 1, 1998. The Commission further
ordered the parties to file testimony in [TEXT MISSING]

         On December 1, 1998, a public hearing was held to consider the RPSA.
Although invited, no public comment was offered. The testimony and exhibits of
Applicants' witnesses Munczinski, Baker, Flaherty, and Davis were entered into
the record, as were the testimony and exhibits of Staff witnesses Witkowski,
Wright and Franks.

         In support of the RPSA, Mr. Munczinski testified that the RPSA,
together with the stipulation approved by Orders No. 5 and 6, provides a fair
sharing of the merger's benefits between SWEPCO's Arkansas customers and the
Applicants. Mr. Munczinski noted that the RPSA provides for five years of annual
rate reductions as well as a direct pass-through of merger-related fuel savings.
He additionally noted that the RPSA does not preclude the Commission from
pursuing other rate actions it may deem appropriate or affect the terms and
conditions of the stipulation approved in Orders No. 5 and 6. Finally, Mr.
Munczinski testified

that the RPSA holds Arkansas retail customers harmless from unforeseen events
that materially diminish the estimated benefits of the merger and from major
deviations from those estimates, including any negative effects of
merger-related market power mitigation measures. In response to questions from
Staff counsel, Mr. Munczinski provided further details of his understanding of
the Applicants' commitments to SWEPCO's Arkansas retail customers T. 219-24.

         Staff witness Mr. Witkowski also testified in support of the RPSA. Mr.
Witkowski pointed out that the RPSA provided specific rate benefits through its
rate reduction rider. Those benefits will continue for at least five years and
potentially beyond that period. The rate reduction will begin at $685,000 in the
first year and increase each year to $1,541,000 in year five. Mr. Witkowski
testified that the RPSA provides a better match of merger savings with costs
than would the PRP and noted that the RPSA also insulates Arkansas ratepayers
from certain merger-related costs. He added that Paragraph 7 of the stipulation
approved by Orders No. 5 and 6 provided additional protection to Arkansas
ratepayers by requiring that they receive any additional benefits or conditions
imposed by order of any other jurisdiction. Mr. Witkowski concluded that the
RPSA, in conjunction with the conditions imposed by Orders No. 5 and 6
adequately protect ratepayers and provide equitable merger benefits for
ratepayers and shareholders.

         The Commission finds that the RPSA represents a fair and reasonable
sharing of merger benefits and costs between Arkansas' SWEPCO customers and
Applicants' shareholders and is in the public interest. This finding is based on
the evidence discussed above, including, specifically, the testimony of Mr.
Munczinski in response to questions from Staff counsel and the condition that
Applicants accept the representations therein. In conjunction with the
conditions specified in Orders No. 5 and 6 and the agreement approved therein,
the RPSA should provide

adequate protection to Arkansas ratepayers from the potential for merger-related
detriment. Nevertheless, there remains the possibility of adverse merger-related
effects resulting from decisions in other jurisdictions, particularly at the
federal level. The RPSA is thus conditionally approved, pending final action by
other relevant authorities. Applicants are directed to continue to file with
this Commission copies of all final, non-appealable orders from other
jurisdictions related to their proposed merger.

         This 17th day of December, 1998.

                    REGULATORY PLAN STIPULATION AND AGREEMENT

         American Electric Power Company, Inc. ("AEP"), Southwestern Electric
Power Company ("SWEPCO"), and Central and South West Corporation ("CSW")
(collectively referred to as the "Applicants"), and the General Staff of the
Arkansas Public Service Commission ("Staff"), jointly referred to as the
"Parties", respectfully submit this Joint Motion stating:

         1. The Applicants commit and agree to implement the rate freeze as
proposed in their Application and supporting testimony.

         2. SWEPCO will implement a net merger savings rider in Arkansas that
will reduce rates to customers by the annual amounts shown in Attachment A
beginning with the first revenue month after the effective date of the merger.
Each individual year's rate reduction will apply for a twelve month period, with
the year five reduction continuing to apply in years following the end of year
five until new base rates for SWEPCO become effective. The annual rate reduction
amounts shown in Attachment A will be allocated to rate classes based upon
revenue requirements to be determined in the pending earnings review. At the end
of the five year period, cost amortization and shareholder saving imputations
shall terminate.

                                                                          PAGE 2



         3. Costs to achieve the merger are those costs incurred to consummate
the merger and combine the operations of AEP and CSW. These costs include, but
are not limited to investment banking fees; consulting and legal services
incurred in connection with obtaining regulatory and shareholder approvals;
transition planning and development costs; employee separation costs including
severance costs, change-in-control payments and retraining costs; systems
integration costs; operations integration costs including telecommunication
costs; and facilities consolidation costs. The costs to achieve the merger are
to be recovered through merger savings. For Arkansas retail jurisdictional
ratemaking purposes, SWEPCO will defer its share of the lesser of the estimated
or actual costs to achieve as incurred over a five year period. These costs will
be amortized over a five year period beginning with the effective date of the
merger. The amortized cost for each year shall be proportionate to the net
merger savings amount reflected in Attachment A for the corresponding year.

         4. If changes in retail base rates of SWEPCO in Arkansas occur within
the first five years after the effective date of the merger, the following rate
treatments will be reflected:

                  (a)      Estimated non-fuel operation and maintenance expense
                           merger savings net of costs-to-achieve will be
                           included in cost of service as an allowable expense.
                           The amount to be included in the cost of service
                           shall be based upon the test year period.

                  (b)      Amortization costs to achieve will be included in
                           cost of service as an allowable expense. The amount
                           to be included in the cost of service shall be based
                           upon the test year period. The unamortized balance of
                           costs to achieve will not be included in rate base
                           and no return will be allowed on the unamortized
                           balance of costs to achieve.

                                                             PAGE 3



         (c)      The merger savings rate reduction rider will continue as
                  described in Paragraph 2 above.

         (d)      It is the intent of the Parties that the provisions of this
                  Paragraph 4 relating to cost amortizations and shareholder
                  savings imputation in the event of a base rate proceeding will
                  terminate five years after the effective date of the merger.

         (e)      Attachment B is an example of the retail base rate treatment
                  described in this section.

         5. If the electric utility industry in Arkansas is restructured prior
to the end of the fifth year after the effective date of the merger, the rider
benefits, cost amortization, and shareholder savings imputation should be
reduced consistent with the functional segregation of unbundled restructured
rates. It is the intent of the Parties that the cost amortizations and
shareholder savings imputations would continue for the five year term for those
functions subject to continued rate of return regulation. It is also the intent
of the Parties that the benefits would continue for the period of time in which
the net merger savings rider set forth in Paragraph 2 remains in effect for
those functions subject to continued rate of return regulation.

         6. All fuel savings shall be passed through to Arkansas retail
customers in accordance with SWEPCO's fuel adjustment clause. After consummation
of the merger, the Applicants agree to report to the Arkansas Public Service
Commission in the monthly full report the amount of energy savings based on a
combined joint dispatch. These savings will be the internal economies for energy
transfers from the East to West Zones within the AEP system.

         7. The Applicants agree to hold harmless the retail customers of SWEPCO
from unforeseen events that materially diminish the estimated benefits of the
merger and from major

deviations from the Applicants' stated representations of estimated merger
benefits. The Applicants also agree to hold harmless the retail customers of
SWEPCO from any negative economic effects of market power mitigation plans
implemented as a part of the merger as determined on a calendar year basis.

         8. This Regulatory Plan Stipulation and Agreement supplements the
conditions reflected in Orders No. 5 and No. 6 in this Docket, dated August 13,
1998 and August 19, 1998, respectively. The Parties specifically agree that the
provisions of Paragraph 7 of the July 10, 1998 Stipulation and Agreement shall
apply to this Regulatory Plan Stipulation and Agreement.

         9. In furtherance of the provisions of Paragraph No. 3 of the
Stipulation and Agreement entered into by the Parties and filed of record July
10, 1998, the Applicants agree to work with the General Staff to address the
issue raised in the Quality of Service Evaluation dated August 11, 1998.

         10. This Regulatory Plan Stipulation and Agreement is expressly
contingent upon receipt of an order by the APSC approving the regulatory plan as
reflected herein, and is contingent upon the completion of the merger.

         11. The Parties agree that this Regulatory Plan Stipulation and
Agreement with regard to the Proposed Regulatory Plan is in the public interest
and should be approved in its entirety by the Commission.

         12. In the event the Commission does not accept, adopt, and approve
this Regulatory Plan Stipulation and Agreement in its entirety and without
modification, the Parties agree that this Regulatory Plan Stipulation and
Agreement shall be void and of no effect. In the event, the Parties agree that
no Party shall be bound by any of the provisions or agreements contained herein,
all Parties shall be deemed to have reserved all their respective rights and
remedies in this

                                                                   EXHIBIT REM-1
                                                                          Page 1

                       PROPOSED STIPULATION AND SETTLEMENT

                        MERGER CONDITIONS/REGULATORY PLAN

1.       SWEPCO shall function under a base rate ceiling set at the level of
         current rates for a period of 5 years after the merger closes. This
         base rate ceiling is not applicable solely under the following
         conditions:

         a.       Changes in statutory federal income tax provisions that result
                  in more than a $16,000,000 net impact on the earnings (income)
                  of SWEPCO;

         b.       A catastrophic "act of God" that has an extreme and long-term
                  impact on the earnings and operations of SWEPCO-La.;

         c.       An increase in the Consumer Price Index - Urban of 10% or more
                  for 2 consecutive years;

         d.       Applicants may file a request with the Commission for changes
                  to the base rates of SWEPCO-La. upon the mandated
                  restructuring or unbundling of electric utility services;

         e.       This condition does not preclude the implementation of a
                  surcharge authorized by statute, Commission decision or as a
                  result of any remand to the Commission from a court
                  proceeding.

         f.       If the purchased power costs incurred by SWEPCO-La. to serve
                  its native load customers during or after the 2001 summer
                  cooling season would, absent this ceiling, cause SWEPCO-La. to
                  seek an increase in its base rates, then the Company may seek
                  relief from this rate ceiling. The Commission's analysis of
                  such a request shall include consideration of all offsets to
                  the requested rate increase, whether such offsets are in the
                  form of lower revenue requirements or cost of capital needs,
                  and these offsets may be used to reduce the need for rate
                  relief.

2.       SWEPCO shall implement a nonfuel savings sharing mechanism (SSM) that
         assures ratepayers will receive timely rate reduction benefits from
         merger-related cost reductions. See attached, Exhibit A.

3.       In connection with the operation of the SSM, SWEPCO shall submit to and
         pay for an audit by the Commission which shall include an examination
         of affiliate transactions.
<PAGE>   2
                                                                   EXHIBIT REM-1
                                                                          Page 2





         The cost of the audit shall be reflected in SWEPCO'S cost of service in
         the appropriate test year. The audit shall be conducted no less than 6
         months and no more than 18 months after the merger is consummated.

4.       The Applicants shall be allowed to defer merger costs associated with
         transaction costs and other costs to achieve net of associated savings
         prior to the operation of the SSM. Ratemaking recovery of the deferred
         costs will not be allowed other than through SWEPCO's retained savings
         computed through the SSM.

5.       SWEPCO shall flow through all Louisiana jurisdictional fuel savings
         from the combined operation of the AEP/CSW systems.

6.       SWEPCO ratepayers shall be held harmless from any increases in fuel
         costs that result from the merger for a period of 10 years. To ensure
         that fuel and purchase power costs shall not increase as a result of
         the merger, the Applicants commit that the current CSW System Operating
         Agreement shall be continued by the Applicants, subject to the right to
         seek FERC-approved modification and subject to the provisions of
         paragraph 12 of the Affiliate Transaction Conditions. The West Zone
         (CSW) shall be economically dispatched, and the Applicant's proposed
         System Integration Agreement shall operate to allow for economic
         exchanges between the East and West Zones to lower fuel and purchased
         power costs for the West Zone. Applicants agree that they will not
         dispatch their system in a manner that will cause increased fuel costs
         to SWEPCO retail ratepayers as a result of the merger.

                  This provision shall function in connection with the hold
         harmless provision related to any mitigation sale as described in
         Paragraph 9 of the Merger Conditions/Regulatory Plan of this
         Stipulation and Settlement. If AEP changes its

                                                                   EXHIBIT REM-1
                                                                          Page 3


         System Integration Agreement, the notice provisions contained in
         Paragraph 12 of the Affiliate Transaction Conditions of this
         Stipulation and Settlement shall apply.

                  To allow the Commission to monitor the fuel costs of
         SWEPCO-La. to ensure that ratepayers do not pay Merger fuel costs as a
         result of the merger and/or any mitigation, measures undertaken by the
         Applicants, the Applicants assume that for a period of 10 years
         following consummation of the merger, SWEPCO shall file yearly fuel and
         purchase power cost reports with the Commission. These reports shall
         provide the following information:

         a.       Calendar year fuel and purchase power cost for SWEPCO and
                  SWEPCO-La.

         b.       A detailed explanation (including detailed workpapers) of how
                  the annual fuel and purchase power costs were derived.

         c.       A detailed explanation with supporting calculations showing
                  how the Applicants incorporated the two hold-harmless merger
                  conditions relating to any mitigation sale. The hold-harmless
                  conditions include (1) the effect of any call-back provision;
                  and (2) the effect on fuel and purchased power costs from any
                  change in system dispatch from the operation of the mitigation
                  sale.

         d.       The annual savings attributable to power interchanges with the
                  East Zone, including detailed workpapers supporting the
                  savings calculation. If fuel and purchase power costs
                  increased due to power interchanges with the East Zone, this
                  calculation shall be shown along with detailed supporting
                  workpapers.

         e.       A sworn statement, consistent with current Commission
                  requirements, with a supporting explanation, by a qualified
                  representative of AEP stating that the fuel and purchase power
                  costs of SWEPCO-La. did not increase as a result of the merger
                  during the calendar year being reported.

7.       SWEPCO shall continue to flow through the Louisiana jurisdictional
         portion of off-system sales margins to ratepayers in accordance with
         the following terms and conditions:

         a.       100% of Louisiana-jurisdictional off-system sales margins up
                  to $874,000 shall be credited to customers. 85% of off-system
                  sales margins between $874,000 and $1,314,000 shall be flowed
                  through to customers, with the remaining 15% to be retained by
                  shareholders. The off-system sales margins of SWEPCO-La. above
<PAGE>   4
                                                                   EXHIBIT REM-1
                                                                          Page 4


                  $1,314,000 shall be shared equally between ratepayers and
                  shareholders. These dollar figures shall apply on a
                  calendar-year basis and shall include margins associated with
                  mitigation sales.

         b.        All off-system sales margins to be credited to the ratepayers
                  of SWEPCO-LA. under this subsection shall be made in the form
                  of credits to the fuel adjustment clause of SWEPCO-La.

         c.       AEP shall report annually to the Commission the capital and
                  operating costs allocable or assigned (directly or indirectly)
                  to SWEPCO-La. of the AEP energy trading organization or
                  operations, based upon the most recent composite allocation
                  factor calculated. This report shall include, without
                  limitation, the total AEP operating and capital costs for the
                  energy trading organization and operations, allocation
                  factors, and all supporting documentation and workpapers. To
                  the extent that the Applicants deem any of this information to
                  be confidential and/or proprietary, they shall so mark the
                  information and those documents shall be treated as such in
                  accordance with the Commission's General Orders, and Rules of
                  Practice and Procedure. The Commission reserves the right to
                  disallow for ratemaking purposes the costs associated with
                  AEP's energy trading function, if the Commission finds these
                  costs excessive in relation to the benefit received by
                  ratepayers.

8.       The Applicants commit and agree that the cost of capital as reflected
         in SWEPCO's rates shall not be adversely affected as a result of AEP's
         acquisition of CSW. The Applicants also agree that subsequent to the
         completion of the merger, the cost of capital for SWEPCO should be set
         commensurate with the risk of SWEPCO and should not be affected by the
         merger. Applicants agree that they will not oppose, in either a
         regulatory proceeding or an appeal of a decision by the LPSC, the
         application of the principle that the determination of the cost of
         capital can be based on the risk attendant to the regulated operations
         of SWEPCO.

9.       SWEPCO's Louisiana ratepayers shall be held harmless from any net cost
         increases resulting from the Applicants mitigation plan (as approved or
         ordered by the FERC) as measured on a calendar year basis.

                                                                          Page 5



10.      SWEPCO and AEP shall commit to maintain and improving service quality
         in the Louisiana jurisdiction in accordance with the Commission's April
         30, 1998 General Order In re: Ensuring Reliable Electric Service
         Quality and as required by the Commission in the Service Quality
         Improvement Program resulting from the Commission's previously
         established investigation into SWEPCO's service quality.

11.      SWEPCO and the merged company commit and agree that any stranded cost
         that SWEPCO may seek to recover will be on a stand-alone basis, and
         will be limited to ownership and contractual interests of SWEPCO in its
         respective assets and obligations. The Applicants and merged company
         agree not to seek or recover any stranded costs associated with the
         existing AEP system from Louisiana customers. The Commission will not
         propose the allocation of any stranded costs associated with the CSW
         system to customers of the existing AEP operating companies.

12.      Applicants agree not to assert in proceedings before the LPSC or in
         appeals of LPSC orders, that the authority of the SEC, as interpreted
         in Ohio Power Co. v. FERC, 954 F.2d 779 (D.C. Cir. 1992) cert. denied,
         498 U.S. 73 (1992) impairs the ability, of the LPSC to examine and
         determine the prudence, reasonableness and necessity of non-power
         affiliate transaction costs of SWEPCO. The parties agree that this
         Agreement does not include a waiver of any arguments that Applicants
         may have with respect to the reasonableness of SEC approved cost
         allocations, as opposed to the reasonableness of the costs themselves.

13.      Commission merger approval shall be final, unless the Commission rules,
         within 45 days of the receipt by the Commission of an order of the FERC
         approving the merger, that Commission approval of the merger is
         rescinded, modified or will be reconsidered. If the Commission does not
         have a B&E meeting within 45 days of receipt of the FERC order
<PAGE>   6
                                                                   EXHIBIT REM-1
                                                                          Page 6


         approving the merger, then the 45 day time period will begin to run on
         the day following the first B&E meeting after the Commission receives
         the FERC's merger order. The applicable time periods for seeking
         rehearing and/or review of the Commission Order will begin to run upon
         the earlier of the expiration of the 45 day time period or the issuance
         of a final Commission order.

14.      The Applicants and the merged company commit and agree that upon
         issuance of final and non-appealable order from the FERC, SEC, or any
         state or federal commission addressing the merger, through stipulation
         or otherwise, providing any benefits to ratepayers of any jurisdiction
         or imposing any conditions on Applicants or the merged Company that
         would benefit the ratepayers of any jurisdiction, such net benefits and
         conditions will be extended to Louisiana retail customers to the extent
         necessary to achieve equivalent net benefits and conditions to
         Louisiana retail customers, provided the proposed merger is ultimately
         consummated.

                        AFFILIATE TRANSACTION CONDITIONS

 CONFIDENTIAL DATA:        WHEN THE FOLLOWING OBLIGATIONS REQUIRE THE COMPANY TO
                           PRODUCE COMPETITIVELY SENSITIVE INFORMATION, UPON
                           REQUEST OF THE COMPANY, THAT INFORMATION SHALL BE
                           MAINTAINED AS CONFIDENTIAL IN ACCORDANCE WITH THE
                           COMMISSION'S RULES OF PRACTICE AND PROCEDURE AND
                           APPLICABLE GENERAL ORDERS.

1.       CSW's domestic electric companies, including SWEPCO, will be core
         businesses for AEP. The Applicants commit, as part of their obligation
         to serve, to continue to meet the needs of SWEPCO's domestic regulated
         customers, including, capital requirements as long as SWEPCO is
         provided an opportunity to earn a fair return on its regulated
         investment in assets to provide service to customers, in accordance
         with regulatory precedent and applicable law.

                                                                   EXHIBIT REM-1
                                                                          Page 7

2.       AEP and SWEPCO will provide the Louisiana Commission access to their
         books and records, and to any records of their subsidiaries and
         affiliates that reasonably relate to regulatory concerns and that
         affect SWFPCO's cost of service and/or revenue requirement.

3.       AEP will cooperate with audits ordered by the Louisiana Commission of
         affiliate transactions between SWEPCO and other AEP affiliates,
         including timely access to books and records and to persons
         knowledgeable regarding affiliate transactions, and will authorize and
         utilize its best efforts to obtain cooperation from its external
         auditor to make available the audit workpapers covering areas that
         affect the costs and pricing of affiliate transactions.

4.       a.       Assets with a net book value in excess of $1 million per
                  transaction, purchased by or transferred to the regulated
                  electric utility (SWEPCO) from an unregulated affiliate either
                  directly or indirectly (through another affiliate), must be
                  valued for purposes of the Louisiana retail rate base (but not
                  necessarily for book accounting purposes) at the lesser of the
                  cost to the originating entity and the affiliated group (CSW
                  or AEP) or the fair market value, unless otherwise authorized
                  by applicable Commission rules, Orders or other Commission
                  requirements.

         b.       Assets with a net book value in excess of $1 million per
                  transaction, sold by or transferred from the regulated
                  electric utility (SWEPCO) to an unregulated affiliate either
                  directly or indirectly (through another affiliate), with the
                  exception of accounts receivable sold by SWEPCO to CSW Credit,
                  must be valued for purposes of the Louisiana retail rate base
                  (but not necessarily for book accounting purposes) at the
                  greater of the cost to SWEPCO or the fair market value, unless

                                                                   EXHIBIT REM-1
                                                                          Page 8


                  otherwise authorized by applicable Commission rules, Orders or
                  other Commission requirements.

5.       The Company shall comply with all requirements contained in the
         Commission's March, 1994 General Order (and any superseding General
         Order) regarding mergers, acquisitions and transfers of ownership and
         control regarding regulated utilities and their assets.

6.       The Company shall notify the Commission in writing at least 90 days in
         advance of a proposed purchase, sale or transfer of assets with a net
         book value in excess of $1 million if such proposed purchase, sale or
         transfer is expected at least 90 days before the anticipated effective
         date of the transaction. With the notice, the Company shall provide
         such information as may be necessary to enable the Commission Staff to
         review the proposed transaction, including, without limitation, the
         identity of the asset to be transferred, the proposed transferor and
         transferee, the value at which the asset will be transferred, the net
         book value of the asset, and the anticipated effect on Louisiana retail
         customers. When such a transaction requires approval of a federal
         agency under no circumstances shall such notification be less than 60
         days in advance or such longer advance period as the applicable federal
         agency may from time to time prescribe. If not provided with the
         initial notice, the Company will provide the Commission with a copy of
         its federal filing at the same time it is submitted to the federal
         agency.

7.       Consistent with applicable Commission and legal precedents and
         Commission General Orders, the Company shall have the burden of proof
         in any subsequent ratemaking, proceeding to demonstrate that such
         purchase, sale or transfer of assets satisfies the requirements of
         applicable Commission and legal precedent and Commission General
         Orders, and will not harm retail ratepayers.

                                                                          Page 9



8.       The Commission reserves the right, in accordance with Commission and
         legal precedents and Commission General Orders, to determine the
         ratemaking treatment of any gains or losses from the sale or transfer
         of assets to affiliates.

9.       For goods and services, including lease costs, sold by SWEPCO to
         unregulated affiliates either directly or indirectly (through another
         affiliate), SWEPCO agrees that it will reflect the higher of cost or
         fair market value in operating income (or as an offset to operating
         expenses) for ratemaking purposes, unless otherwise authorized by
         applicable Commission rules, Orders or other Commission requirements
         (e.g., Commission-approved tariffed rates).

10.      With the exception of transactions between SWEPCO and CSW Credit, Inc.
         and AEPSC, for goods and services, including lease costs, purchased by
         SWEPCO from unregulated affiliates either directly or indirectly
         (through another affiliate), SWEPCO agrees that it will reflect the
         lower of cost or fair market value in operating expenses for ratemaking
         purposes, unless otherwise authorized by applicable Commission rules,
         Orders or other Commission requirements.

11.      For ratemaking and regulatory reporting purposes, SWEPCO shall reflect
         the costs assigned or allocated from affiliate service companies on the
         same basis as if SWEPCO had incurred the costs directly. This condition
         shall not apply to book accounting for affiliate transactions.

12.      The Company shall submit in writing to the Commission any changes it
         proposes to the System Agreement, the System Integration Agreement and
         any other affiliate cost allocation agreements or methodologies that
         affect the allocation or assignment of costs to SWEPCO. The written
         submission to the Commission shall include a description of

                                                                         Page 10


         the changes, the reasons for such changes, and an estimate of the
         impact, on an annual basis, of such changes on SWEPCO's regulated
         costs. To the extent any such changes are filed with the SEC or FERC,
         the Company agrees to utilize its best efforts to notify the Commission
         at least 30 days prior to those filings, and at least 90 days prior to
         the proposed effective date of those changes or as early as reasonably
         practicable, to allow the Commission a timely opportunity to respond to
         such filings. If the documents to be filed with the SEC or the FERC are
         not finalized 30 days prior to the filing, the information required
         above may be provided by letter to the Commission with a copy of the
         SEC or FERC filing to be provided as soon as it is prepared. The filing
         by the Company of this information with the Commission shall not
         constitute acceptance of the proposed changes, the allocation or
         assignment methodologies, or the quantifications for ratemaking
         purposes.

13.      SWEPCO or AEPSC on behalf of SWEPCO may not make any non-emergency
         procurement in excess of $1 million per transaction from an unregulated
         affiliate other than from AEPSC except through a competitive bidding
         process or as otherwise authorized by this Commission. Transactions
         involving the Company and CSW Credit, Inc. (or its successor) for the
         financing of accounts receivables are exempt from this condition.
         Records of all such affiliate transactions must be maintained until the
         Company's next comprehensive retail rate review. In addition, at the
         time of the next comprehensive rate review, all such affiliate
         transactions that were not competitively bid shall be separately
         identified for the Commission by the Company. This identification shall
         include all transactions between the Company and AEPSC in which AEPSC
         acquired the goods or services from another unregulated affiliate.

                                                                         Page 11



14.      If an unregulated business markets a product or service that was
         developed by SWEPCO or paid for by SWEPCO directly or through an
         affiliate, and the product or service is actually used by SWEPCO, all
         profits on the sale of such product or service (based on Louisiana
         retail jurisdiction) shall be split evenly between SWEPCO, which was
         responsible for or shared the cost of developing the product, and the
         unregulated business responsible for marketing the product or service
         to third parties, after deducting all incremental costs associated with
         making such product or service available for sale, including the direct
         cost of marketing such product or service. However, in the event that
         such a product or service developed by SWEPCO to be used in its utility
         business is not actually so used, and subsequently is marketed by the
         unregulated business to third parties, SWEPCO shall be entitled to
         recover all of its costs to develop such product or service before any
         such net profits derived from its marketing shall be so divided. If
         SWEPCO jointly develops such product or service and shares the
         development with other entities, then the profits to be so divided
         shall be SWEPCO's pro rata share of such net profits based on SWEPCO's
         contribution to the development costs.

15.      Subject to the provisions of Paragraph 6 of the Merger Conditions (fuel
         hold harmless), SWEPCO shall continue to purchase, treat, and allocate
         its fuel costs consistently with the Commission General Order dated
         November 6, 1997, In re: Development of Standards Governing the
         Treatment and Allocation of Fuel Costs by Electric Utility Companies,
         including any future amendments to this Order.

16.      In the event of the implementation of electric generation open access
         for Commission-jurisdictional electric utilities, any miles,
         regulations or orders of general applicability adopted by the
         Commission regarding generation assets in an open access environment

         will apply to the company and, to the extent inconsistent with
         provisions of this Order, will govern. No later than six months prior
         to the mandated open access date, the company shall file with the
         Commission any proposed modifications to this Order to address any such
         inconsistencies.

17.      If retail access for SWEPCO-La. is mandated by the Commission, or
         through action by the Federal Energy Regulatory Commission or federal
         legislation, then SWEPCO-La. shall have the right to petition the
         Commission for modifications to the terms of this settlement, including
         the affiliate transaction conditions, that are made necessary by the
         mandating of retail access and its likely impact on the retail rates at
         SWEPCO-La. Any such petition must establish the necessity of the
         proposed modifications and provide appropriate protections to ensure
         that the benefits of this merger are presented for SWEPCO-La. regulated
         customers, including merger savings and the hold harmless provisions
         set forth herein. The Commission will act upon the petition in
         accordance with its normal rules and procedures. This paragraph is not
         intended to limit SWEPCO's right to petition the Commission in the
         event that electric utility unbundling or retail access is ordered by a
         state commission regulating SWEPCO's retail rates, provided that SWEPCO
         must comply with the requirements set forth above in any such petition.

                         SAVINGS SHARING MECHANISM (SSM)

The savings in nonfuel operation and maintenance (O&M) expense resulting from
the merger between CSW and AEP will be quantified in accordance with a formula
based methodology, the SSM, and shared equally between customers and
shareholders. The Louisiana retail jurisdictional share of nonfuel O&M savings
quantified in accordance with the SSM will be flowed through to customers
through an annual surcredit effective initially and for the period beginning on
the first day of the fifteenth month after the consummation of the merger. The
nonfuel savings quantification through the SSM and the surcredit will be updated
for current information on each twelve month anniversary for a total of eight
filings. The surcredit in effect after the eighth filing will remain in effect
unless and until the Commission issues an order in a base rate proceeding. The
annual surcredit will be computed and applied as a uniform percentage of base
revenues.

After the base rate cap expires, the Company will be allowed to file a claim for
a base rate revenue deficiency as an offset to the SSM savings surcredit, which
will be subject to an expedited six month review by the Commission. However, the
surcredit may only be reduced prospectively after the Commission determines and
approves a revenue requirement offset. After the Company's base rate cap
expires, but only through the effective dates of the Company's last required SSM
filing, or in a base rate proceeding initiated by this Commission after the
effective date of the merger, the Company may include its retained savings,
computed pursuant to the SSM, as a cost of service expense in its revenue
requirement filed in conjunction with a comprehensive base rate proceeding. The
Company may not include its retained share of savings, computed pursuant to the
SSM, as a cost of service item in any revenue requirement filing to offset the
SSM. In any base revenue requirement filing through the effective date of the
Company's last required SSM filing, the Company will exclude the test year
amount of the SSM surcredit from its per books and pro forma revenues.

I.       MERGER COSTS TO ACHIEVE, TRANSACTION COSTS, AND CHANGE IN CONTROL
         PAYMENTS.

         The Company is authorized to defer its merger costs to achieve,
         transaction costs, and change in control payments as these terms have
         been defined in the testimony of the
<PAGE>   14
                                                                   EXHIBIT REM-1
                                                                         Page 14


         Applicants' witnesses in this proceeding. The Commission will allow the
         Company to retain its share of the SSM savings in order to amortize its
         deferred costs.

         During the first fourteen months following the consummation of the
         merger, the Company will retain 100% of the merger savings and may
         utilize these savings to reduce the deferrals of its merger costs.
         Commencing in the fifteenth months following the consummation of the
         merger, the Company will retain 50% of the merger savings, computed
         pursuant to the SSM, and may utilize these savings or any portion of
         these savings to reduce the deferrals of its merger costs.

II.      SAVINGS SHARING MECHANISM FORMULA.

         The SSM surcredit and the Company's retained share of merger savings
         will be computed in accordance with the SSM formula. The SSM formula
         compares the Company's future year normalized O&M expense (FYNE) to the
         1998 base year normalized O&M expense (BYNE) escalated for inflation
         and reduced for productivity improvements. The 1998 base year
         normalized O&M expense, prior to the inflation and productivity
         adjustments, is based upon the actual pre-merger level of the Company's
         nonfuel O&M expense adjusted to reflect certain ratemaking
         adjustments., to remove operating lease costs, and to remove certain
         nonrecurring expenses (specifically identifiable and in excess of $1
         million during the twelve-month period), including all merger costs.
         The derivation of the 1998 base year normalized O&M expense is detailed
         on Attachment A.

         For each year subsequent to 1998, the base year normalized O&M will be
         escalated by an inflation factor reflecting the annual increase in the
         Consumer Price Index - Urban (CPI-U) less a 1.1% annual productivity
         adjustment. For each subsequent year, the CYCPI-U will be for the month
         representing the midpoint of the twelve month future year period as
         published on the Consumer Price Indexes home page
         (http://stats.bls.gov/cpihome.htm).

         The future year normalized O&M expense will be based upon the actual
         post merger level of the Company's nonfuel O&M expenses adjusted to
         reflect certain ratemaking adjustments, to remove operating lease
         costs, and to remove certain nonrecurring expenses (specifically
         identifiable and in excess of $1 million during the twelve-month
<PAGE>   15
                                                                   EXHIBIT REM-1
                                                                         Page 15


         period), including all merger related costs and amortizations, in a
         manner similar to that of the base year normalized O&M. The formula for
         the future year normalized O&M is detailed on Attachment B.

         Merger savings will be computed as the difference between the future
         year normalized O&M and the base year normalized O&M, adjusted for
         inflation and productivity improvements as previously described. The
         mercer savings then will be allocated to the Louisiana retail
         jurisdiction (LJA).

         The merger savings for the Louisiana retail jurisdiction under the SSM
         will be computed in accordance with the following formula, consistent
         with the preceding description.

                  Merger Savings = (FYNE - BYNE) * LJA

                  where:

                  FYNE = Future Year Normalized O&M, Computed According to
                  Attachment B

                  BYNE = Base Year Normalized O&M, Computed According to
                  Attachment A, escalated for inflation and reduced for
                  productivity improvement in accordance with the following
                  formula:

                  BYNE = 1998 BYNE O&M * (CYCPI-U/BYCPI-U) - ((1 +.011) to the
                  power of (n - 1)

                  where:

                  CYCPI-U  = Current Year CPI-U (as of the month representing
                           the mid-point of 12-month future year period)

                  BYCPI-U = 1998 Base Year CPI-U (as of June 1998)

                  n        = number of years (stated as a decimal to reflect
                           partial years) computed as mid-point of current year
                           less the mid-point of 1998.

                  LJA      Louisiana retail jurisdiction allocation percentage
                           based upon the most recent calendar year cost of
                           service

         Savings computed pursuant to the SSM formula beginning with the
         fifteenth month after the effective date of the merger will be
         allocated 50% to customers through the SSM surcredit mechanism and
         retained 50% by the Company.

         Attachment C provides an example of the calculation of the SSM and the
         allocation of savings to customers through the surcredit and the
         savings retained by the Company.

III.     TIMING OF SSM STIRCREDIT REDUCTIONS TO CUSTOMERS AND COMMISSION REVIEW.

         The first twelve month (year) period for the computation of SSM savings
         will begin on the first day of the first calendar month after the
         consummation of the merger. Subsequent periods for the computation of
         SSM savings will follow the same twelve month cycle as the first
         period. SWEPCO will make the first SSM filing within the Merger Docket
         U-23327 and pursuant to the Merger Order in Docket U-23327 within 60
         days after the completion of the first twelve month period (within
         fourteen months of the consummation of the merger). The first surcredit
         rate reductions will commence on the first day of the fifteenth month
         following the consummation of the merger, subject to the Commission's
         subsequent review and approval. Likewise, the subsequent surcredit rate
         reductions will commence on the twelve month anniversaries of the first
         surcredit rate reductions, subject to the Commission's subsequent
         review and approval. To implement the surcredit rate reductions, the
         Company's annual filings will include a tariff that will go into effect
         with no further action by the Commission, subject to the Commission's
         subsequent review and approval. Copies of the SSM filings will be
         provided to the Commission's consultants and Special Counsel for
         review, analysis and recommendations to the Commission. In the event
         that the Commission ultimately determines that a larger surcredit rate
         reduction than the one filed by the Company is required, that
         additional reduction shall be effective as of the date the original
         filing became effective. The Company shall make such additional refunds
         or credit customer bills to reflect this effective date.

         In conjunction with the second SSM filing, but within 120 days of the
         end of the second SSM period, the Company also will file detailed
         financial information typically utilized in a revenue requirement
         filing, including a jurisdictional cost of service study. The filings
         of this detailed financial information also will be within the Merger
         Docket U-23327 and pursuant to the Merger Order in Docket U-23327. The
         detailed financial information will be for the most recent twelve
         months ending concurrent with the second SSM savings period. The
         detailed financial information will be provided in the format specified
         in Attachment D. However, the Company and other parties agree that the
         schedules filed pursuant to this provision will not be determinative
         for ratemaking

         purposes. Copies of the detailed financial information will be provided
         to the Commission's consultants and Special Counsel for review,

         provide timely, accurate and comprehensive responses to discovery.

                                   FINAL ORDER

BY THE COMMISSION

            The Corporation Commission of the State of Oklahoma ("Commission"),
being regularly in session, and the undersigned Commissioners being present and
participating, there comes on for consideration and action the report of the
Administrative Law Judge in the above-entitled Cause and the appeals thereto.

            The procedural history in this Cause is set forth at pages 2 and 3
of the Report and Recommendations of the Administrative Law Judge ("Report") and
is incorporated herein as if fully set forth.

                               SUMMARY OF EVIDENCE

            The Summary of Evidence found on pages 7 through 58 of the Report is
adopted as the Summary of Evidence of the Commission.

            Oklahoma Association of Electric Cooperatives ("OAEC") and Municipal
Electric Systems of Oklahoma ("MESO") filed appeals to the Report and argued
that 17 O.S. Section 191.5 does not authorize or allow the exercise of
"conditional approval" by the Commission of a merger. They argued that the
statute provides that a merger application shall be approved unless one of the
five conditions is found, in which case the merger shall be disapproved. They
argued that the ALJ found that market power would exist and competition in
Oklahoma would be harmed, and therefore the ALJ's "conditional approval" was
beyond the jurisdiction of the Commission. (See the Report, at page 58.) OAEC
and MESO further argued that as a result of this finding, under the above
statute, the Commission was without discretion, and must deny the merger.


                                       2
<PAGE>   3
            OG&E argued that if the Commission determined, as a matter of law,
that it does not have the authority to approve the merger with conditions, the
request for approval of the merger should be rejected. In the alternative, if
the Commission found as a matter of law that the Oklahoma merger statute (17
O.S. Sections 191.1 et seq.) did permit approval by the Commission of a
merger subject to conditions. OG&E suggested various conditions. OG&E stated
that if the merger should go forward, that the market and public interest should
be protected from any negative impact of the merger.

            OG&E also noted its disagreement with the ALJ as to the
recommendation regarding line loss being exclusively a Federal Energy Regulatory
Commission jurisdictional issue. It is the position of OG&E that this Commission
does have jurisdiction over the line loss issue. OG&E counsel stated that an
OG&E witness, Stephen Heibson, quantified the line loss issue to be worth at
least $15 million over a 10 year period, as a direct result of the merger and,
OG&E's customers should not have to bear the cost of that loss.

            OG&E stated that the Southwest Power Pool ("SWPP") should be
recognized as the final arbitrator as to the mitigation of the congestion issue,
and requested that the Commission direct the parties to go to the SWPP to
establish appropriate mitigation measures. OG&E recommended that the Merger be
denied for now, without prejudice, until the Applicants could show that the
conditions recommended by this Commission are met and then, upon a showing by
the Applicants that the conditions have been met, the merger could go forward
without harm.

            The Joint Applicants' Brief in Support of the ALJ's Report and
arguments before the Commission, disputed characterization of the ALJ's Report
made by MESO and OAEG. Specifically, the ALJ did not find the existence of the
statutory standard that "substantial" harm


                                       3
<PAGE>   4
would be caused to competition. The ALJ further found that the impact of the
merger which would lessen competition was "negated" by the Joint Applicants'
commitment to engage in joint planning. Specifically, the ALJ's Report states as
follows on page 58:

            "The primary areas of inquiry raised by Intervenor OG&E and others,
            relating to whether the merger would lessen competition in the
            furnishing of public utility service in the state, is negated by the
            Joint Applicants' commitment to engage in joint planning and the
            involvement of the Southwest Power Pool." (emphasis supplied)

            The Joint Applicants argued that the ALJ had not found any of the
conditions existed which would require the Commission to deny the merger.

            The Joint Applicants argued that the order issued in the
Southwestern Public Service Company ("SPS") Public Service Company of Colorado
("PSO") merger approval case (PUD 960000231) was a similar order as that
recommended by the ALJ. The Commission's order, Order No. 405423, approved a
Stipulation which required studies of the proposed interconnection between SPS
and PSCO to be performed. Alternatives to the proposed interconnection,
including using existing high-voltage, direct current interconnections, were to
be examined. Another required study was to examine the options and the cost of
expanding import and export capability between SPS's system and the Southwest
Power Pool.

            By following the recommendations of the ALJ, it was argued the
Commission is stating that none of the conditions exist if the Stipulation is
approved and the Southwest Power Pool is engaged.

            MESO and OAEC argued it was error for the ALJ to strike a portion of
Dr. Sinclair's testimony as being outside of the parameters of the study
guidelines approved for use


                                       4
<PAGE>   5
in this case by Order No. 430244. The essence of their argument is that only the
Joint Applicants were subject to the guidelines approved in Order No. 430244.
Further, it was presented that the testimony was relevant and should be given an
appropriate weight by the Court.

            The Commission finds this argument unpersuasive. All parties agreed
to the guidelines, and it was the testimony of OG&E's witness that OG&E felt
bound by the Commission's order. It is the Commission's decision that all
parties were bound by the guidelines contained in Order No. 430244.
(Attached as Attachment B for reference.)

                     FINDINGS OF FACT AND CONCLUSIONS OF LAW

            After considering the Report of the Administrative Law Judge and the
arguments made during the hearing on exceptions, the Commission makes the
following findings of fact and conclusions of law:

            The Commission finds that it has jurisdiction over this merger and
the authority to issue this order pursuant to 17 O.S. Section 191.1 et seq. and
OAC 165:5-7-57. Further, this Commission has jurisdiction over Public Service
Company of Oklahoma regarding retail rates, and the effect that the merger might
have on those rates, pursuant to 17 O.S. Section 152.153 and Okla.
Const. Art. 9, Section 18.

            Based upon the argument of counsel and an examination of the ALJ's
findings and recommendations, the Commission finds that the adoption of the
ALJ's Report and the recommendations contained therein is within this
Commission's jurisdiction. This Commission issues many orders which contain
directives. It is not unusual for this Commission to allow an applicant
permission to perform some activity (such as in oil and gas orders) and to take
other actions such as implementing a new tariff if certain directives are
followed. This case is no different. All parties except OAEC and MESO stated
that this Commission had the authority to


                                       5
<PAGE>   6
issue an order which would contain directives. This Commission is of the opinion
that its order in the SPS case was proper and that an order in this Cause
adopting the ALJ's Report is within the jurisdiction of this Commission.

            The Commission further finds that the ALJ acted within the scope of
his authority to limit the testimony to the agreed upon study parameters which
were found in Order No. 430244.

            The Commission further finds that although competition would be
lessened as a result of this merger, it does not meet the level required under
Section 191.5(A)(2), that competition would be "substantially" lessened, and
therefore, the Commission finds that the condition contemplated under the
statute does not exist.

            This Commission further finds that the safeguards are present and
that it will continue to have jurisdiction over retail electric competition in
this state.

            The Attorney General for the State of Oklahoma ("Attorney General")
recommended to the Commission that the ALJ Report be adopted as a fair and
reasonable balance of the interests of the parties involved. The Attorney
General further noted that the SWPP is a forum in which both the Applicants and
OG&E are members, and as such, should receive fair consideration.

            Staff recommended that the ALJ Report be adopted as the order of
this Commission. The Staff believes that congestion does exist on the system,
and recommends further study on this issue. Staff noted that the Applicants is
to divest certain assets to address some market power concerns. Certain
mitigation measures are addressed (see page 7, Section 7 of the Stipulation,
Attachment A) which are designed with the intention to allow entry into the
competitive market. The Applicants commit to hold the current jurisdictional
customers


                                       6
<PAGE>   7
harmless and identify that the merger does not create any stranded costs. The
Applicants also have committed to regional planning, either through an
Independent System Operator ("ISO") or a Regional Transmission Organization
("RTO").

            The Commission having considered the record in this Cause and the
Appeals to the Report, adopts the Findings of Fact and Conclusions of Law
contained within the Report of the Administrative Law Judge as the findings of
fact and conclusions of law of the Commission. The Commission therefore finds
that the merger should be approved, consistent with the recommendations of the
ALJ's report.

                                      ORDER

            IT IS THEREFORE THE ORDER OF THE CORPORATION COMMISSION OF THE STATE
OF OKLAHOMA that the findings of the Administrative Law Judge be adopted as the
Findings and Conclusions of this Commission.

            IT IS FURTHER ORDERED that the recommendations of the Administrative
Law Judge, including the Stipulation attached thereto, are hereby adopted by the
Commission. Said Report is attached to this order as "Attachment A".

            IT IS FURTHER ORDERED that the merger between American Electric
Power Company, Inc., Public Service Company of Oklahoma and Center & Southwest
Corporation is hereby approved consistent with the Report of the Administrative
Law Judge.

                           REPORT AND RECOMMENDATIONS

The following is the Report and Recommendations of the Administrative Law Judge
("ALJ") regarding the Joint Application of American Electric Power Company, Inc.
("AEP"), Public Service Company of Oklahoma ("PSO") and Central and South West
Corporation ("CSW") regarding a proposed merger.

                              I. PROCEDURAL HISTORY

      On August 14, 1998, AEP, PSO and CSW ("Applicants" or "Joint Applicants")
filed a Joint Application and Statement requesting this Commission approve a
proposed business combination in which CSW operating companies and subsidiaries,
including PSO, would become operating companies and subsidiaries of AEP.

      The Office of the Attorney General ("AG"), Oklahoma Association of
Electric Cooperatives ("OAEC"), Municipal Electric Systems of Oklahoma, Inc.
("MESO"), International Brotherhood of Electrical Workers ("IBEW"), Oklahoma Gas
and Electric Company ("OG&E"), the Consumer Services Division ("CSD") of the
Oklahoma Corporation Commission ("OCC") and the Public Utility Division of the
OCC ("PUD" or "Staff") were granted intervention.

      On September 25, l998, OG&E filed a Motion to Compel or Dismiss
Application. Also on that date OAEC filed a Motion to Strike Testimony or
Dismiss the Application.

      The Joint Applicants filed a Motion to Withdraw Statement filed October
15, 1998. By agreement of the parties, the Motion was presented to the ALJ on
October 20, 1998. The parties objected to the Commission granting the Motion as
amended by the Joint Applicants. The Commission thereafter issued Order No.
427699 granting the Motion to Withdraw Statement and holding in suspense the
time frame contained within 17 O.S. Section 191.2 and ordering that a new



                                       2
<PAGE>   11
time would commence on the filing of a new Statement upon which the Joint
Applicants would rely for their relief requested in the Cause.

      On October 26, 1998, this Commission issued Order No. 427700 (Order
Regarding Discovery) which stated that the Joint Applicants could file a new
Statement as required by 17 O.S. Section 191.2 which was to include a retail
market study and load flow analysis as described in the Order after which the
statutory time limits contained within 17 O.S. Section 19l.5(b) would commence.

      On November 30, 1998, this Commission issued Order No. 428530 (Amended
Scheduling Order) which was superceded by Order No. 429667, which granted the
AG's Motion to Hold the Hearing in Abeyance.

      On February 25, 1999, the Joint Applicants filed its Amended Statement and
Application after which a Second Amended Scheduling Order (Order No.
430719) was issued March 9, 1999.

      On April 1, 1999, the Joint Applicants filed a Motion to Strike the
Testimony of Dr. Sinclair as being contrary to the directives of Order No.
430244, issued February 16, 1999. Based upon the argument of counsel the ALJ
struck page 30, line 25 through page 33, line 2 and Exhibit RAS-2. An exception
to this ruling was noted to MESO and the OAEC.

      On April 15, 1999, OG&E filed a Motion to Strike the Rebuttal Testimony of
Raymond M. Maliszewski. The oral arguments were held on April 19, 1999, prior to
the taking of testimony. Based upon the arguments of counsel, the ALJ struck
page 14, beginning with line 8 through page 16, line 13 and page 23, line 11
(the word "Furthermore") through line 15 (the end of the sentence with the word
"occur") and Exhibits RMM-4 and RMM-5 of Mr. Maliszewski's testimony. An
exception was noted for the Joint Applicants.


                                       3
<PAGE>   12
      The trial on the merits was held before the ALJ on April 19, 20 and 21,
1999.

                           II. SUMMARY OF STIPULATION

      The Joint Applicants, PUD, CSD, and AG announced that a stipulation had
been reached on various issues between the parties.  Mr. David Carpenter
testified on behalf of the Joint Applicants in support of the Stipulation
(Exhibit No. 209, attached to this Report).

DAVID G. CARPENTER

      Mr. Carpenter testified that the Stipulation provides for net non-fuel and
non-purchase power O & M savings to be shared through a net merger savings rate
rider over the next five years after the effective date of the merger.
Attachment 1 of the Stipulation, column 5, reflected the annual amount of rate
reduction which would be reflected in the rate reduction rider over the next
five years. In the sixth year after the effective date of the merger, the
customer rate reduction rider would increase to $9,409,000 until the next base
rate proceeding after the end of the fifth year at which time the net merger
savings rate reduction rider will be terminated [pp. 176-177].

      Mr. Carpenter further testified that the Stipulation provided that the
cost to achieve the merger would be deferred and amortized. Costs to achieve the
merger are those costs which are incurred within the time period ending two
years after the effective date of the merger. Those costs will be deferred and
amortized over a five-year period of time.

      Attachment 2 sets forth the allocation of the net merger savings rider
between customer classes. Attachment 3 contains an example of how merger savings
will be treated in future base rate cases. The example used was based upon year
three after the effective date of the merger. Mr. Carpenter explained how the
net merger savings for the test year were arrived at, and then how the add-back
to the test year cost of service of the Oklahoma customer rate reduction would
be $5,878,000.


                                       4
<PAGE>   13
      Mr. Carpenter also gave an example if the merger savings were $5 million
higher than predicted and how the formula worked so that retail customers
received all of the additional merger savings over and above those set forth in
Attachment 1.

      In the event that the electric utility industry in Oklahoma is
restructured, and the services provided by PSO are unbundled into regulated and
unregulated services, the merger savings and associated amortization and
shareholder imputation will continue. Therefore, customers will continue to
receive the full level of merger savings on the regulated portion of the rates.

      In the event that a general rate proceeding is initiated by a party other
than PSO, subsequent to industry restructuring and prior to the end of the fifth
year, then the rider benefits, cost amortization, and shareholder net savings
amputations shall be reduced proportionally to the rates of the unregulated,
unbundled services.

      Fuel and purchase power expense savings derived from the merger will be
flowed through the fuel adjustment clause to customers in accordance with the
current practice.

      Other provisions of the Stipulation provide for the Staff and AG to have
access to copies of books and records of AEP and its affiliates as necessary to
review the transactions of PSO. The Joint Applicants have also agreed that
stranded costs, if any that PSO may seek to recover in the future will be on a
stand-alone basis and that PSO does not have any stranded costs currently.
Further, the merger does not create any stranded costs.

      Mr. Carpenter testified that the agreement holds harmless Oklahoma
retail customers from any adverse effects of the mitigation plan filed at the
FERC.

      Section 8 of the Stipulation states that the Joint Applicants will not
seek to increase base rates prior to January 1, 2003, except for certain Force
Majeure provisions. If a review is sought by the Joint Applicants from January
1, 2003 through the end of the fifth year after the effective


                                       5
<PAGE>   14
date of the merger, then the Joint Applicants will make a $5 million reduction
to a revenue requirement otherwise determined to be reasonable by the
Commission.

      The Force Majeure provisions found in Section 9 provide that PSO will have
the burden of proving that its request for relief is a good faith request, that
the event or occurrence was not directly or indirectly caused by PSO, that the
occurrence has at least an annual impact of $6 million, and that PSO has no
direct or indirect control over the event or occurrence.

      The agreement also has provisions regarding a hold harmless for PSO's cost
of capital, a commitment to comply with quality of service standards which were
set forth in Attachment 5, a most favored nations provision which provides that
Oklahoma retail customers will receive the same equivalent net benefits and
conditions as any other state related to settlements of the merger case or
orders related to the merger. In addition, a hold harmless provision for retail
customers from any unforeseen events that materially diminished the estimated
benefits of the merger is contained in the Stipulation.

      The Stipulation at Section 15 contains an agreement that states that if
the merger is not consummated, PSO would not seek to recover merger-related
transition, transaction, or termination fees from Oklahoma retail customers.

      Section 16 states that PSO will not incur any debt or pledge the stock of
PSO in a manner that, upon an affiliate's default, would permit a creditor to
have recourse against the regulated assets of PSO.

      Section 17 is a commitment by the Joint Applicants to join a regional
transmission authority by the latter of six months prior to retail customer
choice or December 31, 2001.


                                       6
<PAGE>   15
      The agreement also provides for Joint Applicants to notify the Commission
at the time the merger is closed and the agreement becomes effective. Further,
the agreement is to not be precedential for other proceedings in the future.

      Mr. Carpenter recommended that the Stipulation be approved.

      Pursuant to a question from the Attorney General's office, Mr.
Carpenter stated that if a rate case takes place after year five from the
effective date of the closing, Section 3(d) provides there will be no estimated
non-fuel operation and maintenance expense savings included in the cost of
service. There will be no amortization of costs to achieve included in the cost
of service and the merger savings rate reduction rider will terminate. In
essence, everything will be the same in setting rates as before the merger.

      At the conclusion of Mr. Carpenter's testimony the Joint Applicants
moved into the record the pre-filed testimonies of Mr. Mark Bailey (Exhibit
Nos. 21 and 78); Mr. David Carpenter (Exhibit No. 120); Mr. Russell Davis
(Exhibit Nos. 16 and 121); Dr. Linn Draper (Exhibit No. 10); Mr. Bruce Evans
(Exhibit Nos. 20 and 77); Mr. Richard Munczinski (Exhibit Nos. 14, 74, 118,
133 and 195); Mr. Thomas Mitchell (Exhibit Nos. 18 and 122); Mr. Armando Pena
(Exhibit 19); Mr. Thomas Shockley (Exhibit No. 11); and Mr. Eric Zausner
(Exhibit No. 138).  The Joint Applicants submitted the testimony as support
for the Stipulation and there were no objections to allowing the testimony to
be submitted into the record and relied upon by the ALJ with all parties
waiving cross-examination of those particular witnesses.

      The following witnesses pre-filed testimony in this Cause regarding
issues that were settled in the Stipulation: Mr. Bill Burnett (Exhibit No.
111) on behalf of CSD; Ms. Evelyn H. Francik (Exhibit No. 58), Ms. Roya Z.
Soltani (Exhibit No. 57) and Mr. Robert C. Thompson (Exhibit No. 113) on
behalf of PUD; and Mr. Michael L. Brosch (Exhibit Nos. 114 and 170) on


                                       7
<PAGE>   16
behalf of the AG. Cross-examination of these witnesses was waived and since
their testimony was filed prior to an agreement being reach, their testimony
should be conformed to the Stipulation.

                            III. SUMMARY OF EVIDENCE

THOMAS J. FLAHERTY

      Mr. Thomas J. Flaherty, the National Partner - Energy Consulting and a
partner in the Deloitte & Touche Consulting Group LLC (Deloitte Consulting)
testified on behalf of the Joint Applicants. Mr. Flaherty's testimony contained
within Exhibits 12 and 119 was accepted into the record without objection.
According to Mr. Flaherty, the merger of the Joint Applicants is anticipated to
result in cost savings that should permit rates in the future to be below the
level that otherwise would have been necessary on a stand-alone basis for either
AEP or CSW operating companies. The merger is estimated to produce approximately
$2.4 billion of nonproduction cost savings, before approximately $248 million of
out-of-pocket costs to achieve these savings, and $193 million of cost cutting
measures planned or initiated by each of the Companies prior to the merger
("premerger initiatives"), and is expected by management of AEP and CSW to
provide an opportunity to benefit all stakeholders, including customers,
shareholders and employees, and result in a stronger, more competitive company.

      The estimated nonproduction cost savings reflect the potential creation of
cost reduction or cost avoidance opportunities through the ability to
consolidate separate, stand-alone operations into a single entity. This
consolidation and integration thus may enable duplicative functions and
positions to be eliminated, similar corporate activities to be combined, avoided
or reduced in scope, external purchases of commodities and services to be
aggregated, and capital expenditures to be avoided.

      The savings, by category, were identified as follows:

</TABLE>

      Recent utility mergers and acquisitions in other states have produced
substantial benefits to customers in the form of operational synergies and cost
savings that reduce rates or slow the rate of growth in rates. Benefits to
customers, however, will not materialize without costs being incurred and risks
being assumed. In merger transactions, shareholders assume the risk that the
merged entity will achieve the strategic, financial, and operational benefits
set forth as the rationale for the proposed combination. To the extent these
objectives are not attained (e.g., failing to realize cost savings),
shareholders suffer from eroded equity value and/or lower returns. It is a well
established regulatory principle that, to compensate for these risks and to
reflect the shareholders' willingness to fund the costs necessary to realize
potential cost savings, the costs to achieve both these savings and the
underlying transaction should be fully recovered and the resulting net cost
savings should be equitably shared with shareholders.

      Mr. Flaherty testified that based on his experience in other mergers, and
on his direct involvement with the identification, evaluation, and
quantification efforts related to estimated cost savings in this and other
transactions, the process utilized by the Joint Applicants for estimating
potential merger cost savings was consistent with the process utilized by other
companies in previous merger transactions. Consequently, Mr. Flaherty believes
that the level of


                                       9
<PAGE>   18
merger savings identified by the Joint Applicants is reasonably attainable
provided that management of the combined company executes its integration plans
in a manner consistent with its intent and how other utilities have pursued
similar opportunities.

      In response to questions from Mr. Shore, Mr. Flaherty testified that he
had done studies in other merger cases where the companies were physically
separated [p. 20]. Those included Public Service Company of Colorado and
Southwestern Public Service Company, Wisconsin Power and Light, Iowa Electric
Light and Power and, Interstate Power, and, Washington Water Power and Sierra
Pacific Resources [p. 19].

      Mr. Flaherty further testified that as a general proposition, there arc
more synergies for saving money when two merging companies are
similarly-sized entities. AEP and CSW are not similarly-sized utilities.

      Mr. Flaherty further testified that studies regarding possible merger
benefits had been conducted on two prior occasions in 1997, and that the results
in those undertakings were similar in total amounts as the work which was
performed subsequent to the announcement of the merger [p. 25].

      In answering questions from Mr. Stewart, Mr. Flaherty testified that
the total savings were approximately S2 billion [p. 28].

      In calculating proposed merger savings, Mr. Flaherty used 3% for general
inflation, 4% for wages and salaries, and 5% for certain other professional
services category as escalation factors. The escalation factors reflected the
Joint Applicants' stand-alone forecast assumptions as well as from the
Conference Board Group, which includes some 50 economists [p. 34].

WILLIAM HIERONYMOUS

      Dr. William Hieronymous, Senior Vice-President of PHB-Hagler Bailly,
testified on behalf of the Joint Applicants. Dr. Hieronymous' testimony
contained in Exhibits 17, 80, 137


                                       10
<PAGE>   19
and 193 was accepted into the record without objections. Dr. Hieronymous
prepared the Applicants' analysis of the competitive effects of the merger, and
sponsored both direct and rebuttal testimony for this proceeding.

      Dr. Hieronymous' testimony was based on the FERC's requirements and this
Commission's order relating to the effect of the merger on retail competition in
Oklahoma. His fundamental conclusion is that the merger has no substantial
negative impact on competition. The analysis conducted according to FERC
requirements showed no negative impact on any Oklahoma market when the
Applicants' proposed mitigation measures are taken into account. Sensitivities
were conducted that assumed greater transmission capability, lower transmission
rates and AEP joining the Midwest ISO. These showed a similar lack of impact on
competition.

      His analysis demonstrates that the merger will not turn CSW and PSO into
significantly more powerful competitors in Oklahoma. AEP historically has made
no sales whatsoever into Oklahoma. According to Dr. Hieronymous, AEP is not a
competitor in the Oklahoma market today, nor is it likely to become one because
it has more lucrative markets elsewhere.

      The 250 MW transmission path that CSW has reserved to implement the System
Integration Agreement does have a small competitive impact on the market. By
bringing 250 MW of low cost AEP power into CSW, irrespective of whether AEP has
better alternatives elsewhere, the merger creates savings for Oklahoma
consumers. It also increases Applicants' market share. To mitigate the impact of
the 250 MW transfer, Applicants have offered to sell 550 MW of capacity to
competitors which helps deconcentrate those markets in Oklahoma and Texas in
which CSW was the largest seller.

      Pursuant to this Commission's Order No. 427700, his direct testimony also
includes an analysis of the impacts of loop flow on market power. The transfer
of AEP energy through


                                       11
<PAGE>   20
Ameren causes somewhat greater loop flow effects than the imports it replaces.
This results in an increase in concentration in some third-party markets in some
time periods. Applicants' share of these markets is small and, indeed, smaller
than CSW's share was before the merger. Any increase in concentration is due to
the increased market share of the incumbent in that market, not CSW.

      His rebuttal testimony addresses the supposed harm that the merger causes
to competition in these non-CSW areas. The Applicants do not gain market power.
According to Dr. Hieronymous, no intervenor has presented evidence to
demonstrate that the merger of CSW with AEP will cause CSW to have increased
market power. The supposed harm from the merger is that it caused Applicants to
reserve transmission that no other party wanted to reserve. Applicants have
mitigated any increase in their own market share that results. He rejected
OG&E's position that Applicants must also mitigate the increase in OG&E's market
share.

      The idea that a party that contracts for firm transmission service must
compensate any other party that is adversely affected by resulting loop flows is
directly contrary to FERC policy. The fact that the contract was related to a
merger does not clothe unintended and minor effects of loop flow on third
parties with any market power significance.

      The other market power issue raised by Intervenors is whether Applicants'
mitigation effectively transfers control to the buyer of the interim contract of
the divested capacity. The interim contract fully transfers the economic
interest in the contracted power. This reduction in Applicants' share of the
market is the purpose of the mitigation. Because Applicants must deliver on the
contract under all foreseen circumstances, the fact that they have not
transferred direct ownership in any specific plant does not matter.


                                       12
<PAGE>   21
      Concerning the divestiture of the Northeastern capacity, Intervenors'
complaint is that PSO will continue to be the plant operator and will control
the timing of scheduled outages. Abuse of such control would require scheduling
outages when prices are predictably high. Even if one ignores the regulatory
response to this action, the fact is that the owner of the divested capacity
would have grounds to sue CSW and have every prospect of collecting damages.

      On cross-examination by Mr. Selph, Dr. Hieronymous testified that his
firm developed a competitive analysis screening model designed to address
issues and analysis that are required by Appendix A of the FERC Merger Policy
Statement which his firm used in regard to this merger [p. 45, ls. 10-17].
The model provided a method to identify whether the merger presents market
power concerns [p. 45, ls. 18-21].  In the Merger Policy Statement, FERC
adopted the Department of Justice/Federal Trade Commission Merger Guidelines
which are intended to evaluate the competitive effects of a proposed merger
on competition [p. 45, ls. 24-25 and p. 46, ls. 1-9].  The Guidelines set out
steps for merger analysis to assess, among other things, market concentration
by use of the Herfindahl-Hirschman Index ("HHI") [p. 46, ls. 10-21].  Dr.
Hieronymous testified that in regard to the AEP-CSW merger, his firm's
screening model for economic capacity before mitigation identified five (5)
screen failures outside of CSW, four of which occurred in the State of
Oklahoma [p. 46, ls. 22-25 and p. 47, ls. 1-4].  He stated that the model
showed an HHI change for the summer peak period of 66 points relating to OG&E
and 57 points relating to Western Farmers Electric Cooperative ("Western
Farmers") [p. 47, Is. 20-22 and p. 48, ls. 4-9].  He also stated that the
model showed an HHI change for the summer off-peak period of 175 points
relating to OG&E and 70 points relating to Western Farmers [p. 47, ls. 23-25
and p. 48, ls. 10-11].  He stated that under the Guidelines, for a highly
concentrated market, if the HHI change exceeds 50, the Guidelines provide
that the merger potentially raises


                                       13
<PAGE>   22
significant competitive concerns and if the change in HHI exceeds 100, it is
presumed that the merger is likely to create or enhance market power, absent
mitigation [p. 48, ls. 12-19]. Dr. Hieronymous stated that the Applicants'
merger proposal includes mitigation so he is principally looking at the results
of the merger inclusive of the proposed mitigation [p. 48, l. 25 and p. 49, ls.
1-3]. Dr. Hieronymous accepted the assertion that the Applicants' 250 megawatts
reservation results in the reduction in import capability into some of the
Oklahoma destination markets [p. 49, ls. 18-25 and p. 50, l. 1]. He also stated
that the reservation does have some adverse impacts on the availability of
transmission into Oklahoma [p. 50, ls. 5-11].

      On redirect examination, Dr. Hieronymous testified that his studies
pointed out that, after mitigation, the summer peak and summer off-peak
periods in terms of the concentrating effect of the transfer on OG&E's and
Western Farmers' markets showed a change in HHI of -5 points and -23 points,
respectively, as to OG&E and -47 points and -48 points, respectively, as to
Western Farmers, and thus, he stated the mitigation, coupled with the
transfer, deconcentrates those markets [p. 52, ls. 12-25 and p. 53, ls. 1-15].

MARK D. ROBERSON

      Mr. Mark D. Roberson, Vice President - Regulatory Affairs for CSW,
testified on behalf of the Joint Applicants. Mr. Roberson's testimony contained
in Exhibits 15, 75, 134 and 194 were accepted into the record without
objections. According to Mr. Roberson, during the first ten years following
closing, the proposed AEP/CSW merger is anticipated to provide net non-fuel
savings of approximately $152 million and fuel savings of approximately $11.8
million to PSO's Oklahoma retail jurisdiction.

      It was Mr. Roberson's opinion that the proposed merger will not impair
retail competition in Oklahoma or adversely affect PSO's ability to fulfill its
contractual commitments. The companies will integrate their system operations
according to the terms of the System Integration


                                       14
<PAGE>   23
Agreement, which has been presented for approval at the FERC. In addition to
various state regulatory filings, approvals are being requested from the FERC,
the Securities and Exchange Commission under the Public Utility Holding Company
Act of 1935, the Federal Trade Commission and Department of Justice under the
Hart-Scott-Rodino Act, the Nuclear Regulatory Commission and the Federal
Communications Commission.

      Mr. Roberson's testimony was given before the parties to the
Stipulation had reached an agreement.  Therefore, portions of Mr. Roberson's
pre-filed testimony appear to be inconsistent with the Stipulation.

      CSW and AEP are willing to protect customers from any changes in PSO's
stranded costs arising from the merger, and will not oppose a Commission order
approving the merger which contains a merger condition limiting the basis of
PSO's stranded costs to PSO's assets and obligations. Further, it is not
necessary to perform additional production cost modeling of different power
interchange levels between AEP and CSW to find that the merger is not
detrimental to the public interest. The production cost studies performed based
upon the interchange levels which have been secured show that the merger does
produce fuel cost benefits for customers.

      Mr. Roberson also committed that AEP and CSW are willing to protect PSO
customers from any adverse impacts from cost changes which arise due to
implementation of the proposed market power mitigation plan.

      In explaining the mitigation plan, Mr. Roberson testified the Joint
Applicants had committed at the FERC to divest 300 megawatts (MW) of capacity at
PSO's Northeastern Plant (Units 3 and 4) in the Southwest Power Pool (SPP) and
250 MW of capacity at CSW Energy's Frontera Plant in the Electric Reliability
Council of Texas ("ERCOT") upon the fulfillment of


                                       15
<PAGE>   24
certain conditions to mitigate potential market power concerns. In the time
between the merger's closing and the fulfillment of the specified conditions,
interim energy sales will be used to mitigate market power concerns. In the SPP,
the sales will be interim system sales totaling 300 MW that are available all
hours of the year, but which are subject to repurchase by AEP/CSW in the case of
a system emergency. If the company recalls generation capacity, in the event of
a system emergency pursuant to SPP operating rules or the CSW System Operating
Agreement, it will make energy sold in the interim financially firm to the
buyers affected. In ERCOT, the interim sale will be a unit sale for 250 MW of
energy from CSWE's Frontera Plant. The interim sales will cease when the
capacity is divested [pp. 57-58].

      The sales revenues and incremental costs from the interim system sales in
the SPP transactions will be treated for ratemaking purposes like all other
off-system sales transactions. The Joint Applicants have committed to hold
customers harmless from negative net margins (revenues, less incremental costs
of energy and repurchased power) that might occur on an annual basis from the
interim system sale in the SPP.

      For the Northeastern Units owned by PSO, divestiture would not occur until
after implementation of retail competition in Oklahoma (which is now targeted
for July 1, 2002).

      The Joint Applicants have developed a procedure for measurement of margins
arising from the proposed 300 MW mitigation interim sale, and for crediting the
customer share of margins on an annual basis, which will be sold from the CSW
System and delivered in the Southwest Power Pool. The buyer will be responsible
for paying $14/MWh for energy delivered, and will make a fixed payment,
determined by auction, for the right to receive the low-cost energy. The Joint
Applicants will incur incremental costs for fuel to produce the energy, for
repurchase of energy at market prices when required to serve native load, and
for


                                       16
<PAGE>   25
hedges to manage fuel and gas price risks associated with the transaction. Each
of these cost components must be accurately measured to determine the economic
benefit resulting from the transaction.

      An hourly calculation of the incremental cost is required to ensure that
the fuel cost incurred to serve retail customers is based on the lowest
reasonable cost from available sources of generation, referred to as Regulatory
Mitigation Reconstruction. An hourly redispatch process is necessary to allocate
lower cost sources of generation to native load, and then to allocate the higher
cost resources for off-system transactions, such as the mitigation sale. By
performing an hourly calculation, the procedure ensures that ratepayers are
charged the lower-cost resources, and that off-system transactions are charged
the higher-cost resources.

      All costs and revenues from the transaction will be added together to
determine the margin. Since the incremental unit dispatched for PSO is often
natural gas, the incremental dispatch costs will frequently exceed the S14/MWh
energy revenues. The revenues from the auction payment from the buyer must be
reflected in the determination by the margin. Buyers will base their payment
upon their estimates of market prices, which are expected to be significantly
higher than $14/MWh on an annual basis. Positive net gains will be flowed
through to customers consistent with the sharing procedures in effect for
off-system sale gains. If a negative gain occurred for a twelve-month period, it
would be absorbed by shareholders.

      The Regulatory Mitigation Reconstruction cost procedure will provide a
reliable mechanism for a meaningful "hold harmless" protection for customers
from the impacts of the market power mitigation transaction. An annual sharing
mechanism for the benefits of the mitigation sale will most fairly capture all
of the cost changes arising from the sale and share the net benefits with
customers.


                                       17
<PAGE>   26
      Regarding the proposed divestiture of Northeastern capacity, such
mitigation is not planned until generation prices are no longer subject to
regulation in Oklahoma, and therefore hold harmless protections are not required
from the effects of divestiture. However, if the Joint Applicants' plan for
divestiture changes, and divestiture is required earlier, hold harmless
provisions could be required, and the Joint Applicants are willing to propose
appropriate provisions for OCC approval. Applicants are willing to accept fair
hold harmless conditions for the mitigation sale as a condition of merger
approval [p. 61].

      In response to questions from Mr. Speegle, Mr. Roberson stated that the
purchaser of the Northeastern Units would be required to enter into an
operating agreement which would set forth the terms and conditions of the
joint owners' participation in the plant [p. 62].  Further, Mr. Roberson was
not aware of any draft operating agreements in existence for the
divestiture.  It was further generally contemplated that PSO would retain
certain management rights and the right to operate the plant [p. 63].

      Mr. Shore inquired regarding the proposed estimated $11.8 million in
fuel savings to be realized by customers of PSO over a ten-year period.
According to Mr. Roberson, the savings are derived from PSO customers
receiving AEP's coal generation which in general had a lower variable cost
than CSW companies' incremental gas generation [p. 65].

      In response to questions regarding the mitigation proposal, Mr. Roberson
testified that two conditions had to be satisfied prior to divestiture of 300 MW
at Northeastern. Those conditions were that a pooling of interest accounting had
to be satisfied for the merger as a whole and PSO would not have an obligation
to serve at least 300 MW of native load [p. 68]. The interim sale would continue
until those conditions would be satisfied [p. 70]. It is contemplated that a
bidding process would be used for the interim sale [p. 70].


                                       18
<PAGE>   27
      In response to questions from Mr. Stewart, Mr. Roberson stated that the
$11.8 million in fuel savings will not arise from the sale of capacity but
from the energy exchanges that occur hour-to-hour [p. 72].

      Mr. Roberson describes the interim sale as a sale of firm energy [p. 72].
In describing when PSO could repurchase in the event of a system emergency, Mr.
Roberson explained that this event would only be triggered when PSO would not
have other resources available either internally or through the points of
interconnection that PSO has with others [p. 74]. Although the party purchasing
the energy will lose that energy, that party will still receive the market price
benefit associated with that energy [p. 74]. Whether or not the purchasing party
would be able to secure electricity elsewhere, Mr. Roberson stated would depend
on where the buyer was located and where the buyer was trying to deliver the
power [p. 75].

      In response to questions from Ms. Morgan, Mr. Roberson stated that any
gains from the interim sale of the 300 MW should be treated as off-system sales
are currently, i.e., 25% to shareholders and 75% to customers.

      In response to questions from Ms. Jacobson, Mr. Roberson testified that
under the current system of regulation in Oklahoma, PSO would have no
stranded costs and the merger does not create any stranded costs [p. 89].

      On cross-examination by Mr. Stewart, Mr. Roberson said that the interim
sale of energy under Applicants' mitigation plan is "firm" except for the
need for PSO to recall the energy to serve its native load and then only when
PSO is physically unable to acquire resources from the market [p. 72, ls. 1-4
and 20-24].  If the energy were recalled by PSO, Mr. Roberson stated it is
possible, depending on where the owner was located, that there might not be
any power to replace that energy [p. 73, ls. 15-24].  He also stated he would
not be able to speculate as to


                                       19
<PAGE>   28
whether the buyer could replace the resources [p. 75, ls. 6-8]. The buyer of
that energy would then be entitled to receive as compensation for the inability
to replace the power, the market price of the energy according to a published
index [p. 74, ls. 21-24 and p. 75, ls. 1 - 2]. This situation could cause the
buyer of the energy to have physical problems which Mr. Roberson characterized
as load shedding or interruptible customer shedding [p. 76, ls. 7-13].

      Mr. Roberson also testified under cross-examination that the $11.8
million savings for PSO customers relates to hour-to-hour electricity
exchanges from AEP to CSW [p. 70, ls. 21-25 and p. 71, ls. 1-11]. He had
previously testified that the savings related to a ten-year period [p. 55,
Is. 8-10].  Mr. Roberson explained that because of the lower costs structure
of AEP with respect to variable costs, because coal is cheaper than gas, the
Applicants' studies show that the predominant power flow direction is east to
west [p. 71, ls. 11-18], although the agreement provides go either way.

      Concerning the portion of the Applicants' mitigation measures relating
to the sale of capacity, Mr. Roberson testified that the terms of such a sale
have not yet been worked out but that AEP might want some provision providing
for a right of first refusal for AEP should the buyer of that capacity decide
to sell its interest [p. 78, ls. 23-25 and p. 79, ls. 1-9].  He testified
that AEP does have some agreements today for existing joint units that have
right of first refusal provisions.  He did not know whether such a provision
would be part of a future agreement [p. 80, Is. 9-13].

STEPHEN B. JONES

      Mr. Stephen B. Jones, the Director of Issues Management for CSW,
testified on behalf of the Joint Applicants.  Mr. Jones' testimony contained
in Exhibit 135 was accepted into the record without objection.  Mr. Jones
explained the market power mitigation measures proposed by the


                                       20
<PAGE>   29
Joint Applicants in their application for approval of the merger at the FERC. He
attached his FERC testimony as an exhibit.

      The mitigation plan proposes the divestiture of ownership interests in two
CSW plants. The Frontera plant located in the Electric Reliability Council of
Texas (ERCOT) and the Northeastern plant located in the Southwest Power Pool
(SPP). The Frontera plant is under construction and owned by CSW Energy, Inc.
When completed, the facility will be an exempt wholesale generator merchant
plant. The Northeastern plant is located in Oklahoma and serves PSO.

      Joint Applicants will divest an ownership interest in 300 MW of the
Northeastern plant in two equal lots of 150 MW from Unit 3 and Unit 4 through an
auction process devised to obtain the greatest possible value for the sale. No
buyer can purchase both lots, and the divestiture cannot cause violations of the
post-merger Herfindahl-Hirschman Index ("HHIs") in any CSW/SPP destination
market or contiguous destination market.

      PSO will maintain operational control of the Northeastern plant through an
operating agreement with the purchasers, who will have the right to capacity at
any time and to the extent that the units are available for operation. In
addition, at any time the units are available and PSO is not fully scheduling
PSO's interests in the units, the purchasers will have the right to purchase at
marginal cost any energy available. PSO will have a reciprocal right. The
operating agreement will also provide for mutually agreed upon maintenance
schedules and coordination on other operating matters.

      This divestiture cannot happen unless both of the following have occurred:

      -     two years have passed since consummation of the merger as
            required by pooling of interest accounting; and


                                       21
<PAGE>   30
      -     retail access and entry by alternate suppliers in Oklahoma has
            caused a reduction in PSO's native load obligations to where the 300
            MW of divested capacity is no longer required to satisfy SPP
            reliability criteria.

The divestiture of the Northeastern units was selected because these units have
the location and price characteristics necessary to provide effective mitigation
in the CSW/SPP region and Oklahoma has set a statutory goal of full consumer
choice by July 1, 2002. Consequently, the introduction of retail competitors
into Oklahoma will allow the divestiture of these units without undermining
PSO's ability to fulfill its native load obligation.

      Mr. Jones testified the OCC should find that the merger will not have an
adverse impact on wholesale and retail competition within the state, and that
the mitigation proposal will not have an adverse impact on customers served by
PSO.

      In response to questions from Mr. Speegle, Mr. Jones testified he was
familiar with how jointly owned plants are operated and he assumed that PSO
personnel would continue to operate the Northeast Plant [p. 98].  Further,
the operating agreement would include how the plant was going to be
scheduled, O& M costs, the governing structure, and when capital additions
are made to the plant [p. 100].

      The right of first refusal would not be contained within the operating
agreement if it would ruin the mitigation purpose of the divestiture [p. 101].

      In response to questions from Mr. Shore, Mr. Jones testified that the
reason for having two purchasers of 150 MW blocks is to avoid creating a market
power problem [p. 102]. Mr. Jones further testified that if the Oklahoma
Legislature passes a statute in the next session, or sometime before 2002, that
says all generation shall be unregulated and electric utilities will have no
obligation to native load, then one of the conditions for divestiture will have
been met. However, if the Legislature says that there shall be a transition
period where default customers will be supplied by PSO, even though it is
unbundled as part of the restructuring process, then


                                       22
<PAGE>   31
the condition might not be met. However, whenever PSO has 300 MW or more of
capacity in excess of those obligations then the divestiture can occur [pp.
103-104].

      In response to questions from Mr. Stewart, Mr. Jones testified that AEP
companies would not be allowed to purchase the capacity, nor a company which
would possess market power after the purchase of the capacity [p. 105].  Mr.
Jones further testified that there is no problem with OG&E bidding on the
capacity [p. 106].  Pursuant to re-direct, Mr. Jones testified that as part
of the condition of the offer of sale that HHI violations do not occur as a
result of the sale [p. 111].  It would be more difficult for OG&E to bid on
Northeastern and not exceed the market power test than an entity remote to
Oklahoma [p. 112, ls. 2-6].

RAYMOND M. MALISZEWSKI

      Mr. Raymond M. Maliszewski testified on behalf of the Joint Applicants.
Mr. Maliszewski's testimony contained in Exhibits 136 and 192 was accepted into
the record without objections. The participants in this case agreed that the
Applicants would conduct a system performance analysis of the bulk transmission
networks in Oklahoma to determine the impact of the proposed 250 MW power
transfer from AEP to CSW.

      Applicants evaluated load flow performance of the Oklahoma systems for the
summer, spring/fall and winter seasons of 1999 with and without the AEP to CSW
power transfer. Applicants compared the results of with and without cases to
evaluate system performance and provide an indication of the AEP to CSW transfer
impact.

      The Applicants' analysis examined:

      a)    the incremental impact of the 250 MW transfer on flows on all the
            bulk transmission lines in Oklahoma as well as the rest of the
            interconnected network;

      b)    the ability of the Oklahoma transmission networks to support single
            contingency operations, i.e., the outage of each transmission line;
            and


                                       23
<PAGE>   32
      c)    the impact that the power transfer would have on the power transfer
            capabilities of the other Oklahoma utilities with each of the
            directly connected neighboring systems.

      According to Mr. Maliszewski, the parties agreed that the Applicants would
perform a conventional linear load flow analysis. The Applicants also agreed to
verify these results with an AC load flow analysis as required to take into
account the voltage performance considerations of the Oklahoma systems if they
are significant. The Applicants' results are documented in Exhibit RMM-5.

      According to Mr. Maliszewski, the analysis showed:

            -     The 250 MW AEP to CSW power transfer causes small changes
                  in incremental power flows on the Oklahoma bulk transmission
                  facilities that are widely distributed throughout the network,
                  ranging from 0 MW to about 30 MW on 345 kV lines in Oklahoma.
                  Considering that the 345 kV lines typically carry several
                  hundred MW and have thermal capacity of at least 1000 to 1200
                  MW, these are relatively small changes. In some cases there
                  will be no change, in others, a small amount of reduction, and
                  in still others a slight increase.

            -     The system is capable of supporting transmission outages with
                  the 250 MW power transfer. Thus, the reliability of power
                  supply to Oklahoma customers is not undermined by the 250 MW
                  power transfer.

            -     The AEP/CSW power transfer will have no more impact on
                  Oklahoma line flow patterns and the ability of Oklahoma
                  utilities to import and export energy than power transfers
                  made by any other Oklahoma system.  Any change in
                  generation dispatch or power transfer in any Oklahoma
                  system will result in a change in power flow patterns on
                  every other Oklahoma system, some of which will be an
                  addition to base power flows, while others will be a
                  subtraction.

            -     In general, over the entire year, spring, fall, winter and
                  summer, there will continue to be significant levels of ATC
                  available to the other Oklahoma systems. In those situations
                  where no transfer capability existed to begin with, due to
                  some existing inherent limitation, this condition cannot
                  change.


                                       24
<PAGE>   33
Overall, it was Mr. Maliszewski' s conclusion that these studies clearly
demonstrate that the AEP to CSW 250 MW power transfer will not have a material
detrimental impact on the Oklahoma bulk transmission network.

      OG&E claimed that Applicants' study was flawed because Applicants had used
an incorrect transformer rating that OG&E had supplied. In his rebuttal
testimony, Mr. Maliszewski described a revised study of OG&E's ability to import
power from the systems to which OG&E is interconnected. That revised study
showed that the conclusions drawn from Applicants' original analysis were not
affected by the change in the transformer rating. In particular, Applicants'
earlier finding that even before the AEP/CSW transfer OG&E would be unable to
import energy from the Entergy system was still true even with the higher rating
on the OG&E transformer at the Fort Smith station. OG&E's transformers at Fort
Smith already operate very near their emergency ratings in contingency
conditions, and had little margin remaining to accommodate load growth or
contingency conditions.

      OG&E also claimed that it would suffer significantly increased losses
due to the AEP to CSW transfer.  Mr. Maliszewski explained the flaws in
OG&E's analysis [p. 117,l. 24].

      Based on its flawed analyses, OG&E made claim to compensation for the cost
of adding a new transformer at Fort Smith and to cover the cost of increased
losses. Mr. Maliszewski testified that such remedies are at odds with
established industry practice, and that granting the requested relief would have
the effect of inhibiting the competition that Oklahoma and the federal
government are seeking to foster.

      In response to questions from Mr. Speegle, Mr. Maliszewski testified that
transmission service is requested from transmission owners through the processes
that have been established


                                       25
<PAGE>   34
by the FERC, including using the OASIS. Once the reservation has been granted it
is filed before the FERC and not at the Oklahoma Corporation Commission [p.
122].

      In response to questions from Mr. Shore, Mr. Maliszewski testified that
the parties had agreed that Applicants should perform an all encompassing study
of the interconnected network between and including the AEP service area and the
CSW and other Oklahoma systems. Mr. Maliszewski further explained that the
parties had discussed how the study was to be carried out, what base cases were
to be used, the source of the base case information, the load levels that would
be studied and the kinds of system performance analyses that the Applicants
would undertake [pp. 123-125]. Mr. Maliszewski testified that Applicants agreed
to the performance of the interconnected network for the outage of every key
transmission element within the interconnected network to determine whether
there would be any detrimental impacts resulting from the 250 MW transaction.
Applicants also undertook to examine the transfer capability between each
directly connected utility within Oklahoma, with and without the 250 MW
transaction, in order to determine whether the transaction had any impact on
those transfer capabilities [pp. 128-129].

      In a February 4, 1999 technical conference, of the parties' engineers,
OG&E had requested that the Joint Applicants also examine what effect the
proposed 300 MW divestiture of capacity at the Northeastern plant would have on
the Oklahoma systems. The Joint Applicants were of the opinion that it was not
appropriate to make such a study using a base case year of 1999 when the
proposed divestiture would not occur earlier than 2002. However, the Joint
Applicants agreed to carry out an analysis, which was discussed in Mr.
Maliszewski's testimony [p. 129].


                                       26
<PAGE>   35
      In response to questions from Mr. Stewart, Mr. Maliszewski stated that
the conduct of load flow studies is a well-established industry practice [p.
133, ls. 9-10].

      According to Mr. Maliszewski, the agreement among the parties
contemplated a basic DC analysis, which does not consider certain system
characteristics but allows expeditious analysis of hundreds of system
contingencies and in most cases produces accurate results.  Applicants used
the same software and study process that the Southwest Power Pool uses in
making similar studies.  Mr. Maliszewski testified that the agreement among
the parties also contemplated that the DC analysis would be supplemented by
AC analysis, which does consider system characteristics such as resistance
and voltage levels, as required [p. 135, ls. 14-24]. [p. 7, 1.9 of rebuttal]
in his rebuttal testimony, Mr. Maliszewski explained that, contrary to the
claim of OG&E witness Kuebeck, the Applicants had performed the required AC
analyses [pp. 135-140].

      According to Mr. Maliszewski the agreement reached between the parties at
the technical conference called for a DC Analysis because a conventional linear
load flow analysis was simply an alternative terminology for a DC Analysis. DC
Analysis is by its very nature a linear analysis, so that when one says a
conventional linear analysis, it was understood by all engineers that DC load
flow analysis would be used [p. 135, ls. 8-13].

      In response to questions from Ms. Jacobson, Mr. Maliszewski testified
that he had seen no evidence that the merger would burden the Oklahoma
transmission network to an extent that would require transmission system
reinforcement [p. 167, ls. 12-16].

      On cross-examination by Mr. Stewart, Mr. Maliszewski testified that the
six base cases studied by the Applicants were full-blown legitimate AC load
flow base cases [p. 135, ls. 14-17].  Mr. Maliszewski testified that the
determination of whether to use an AC or DC analysis is a


                                       27
<PAGE>   36
function of the purpose of the study to begin with and the judgment of the
engineer who is reviewing the result to determine whether the study results are
sufficient for his purposes [p. 138, ls. 19-23]. He stated that in its
calculation procedure the DC analysis does not capture resistance, reactive
aspects or voltage variations, that you would expect to see on the AC solution
[p. 140, ls. 6-10]. It was for that reason that relative to the conventional
load flow analysis that a supplemental AC analysis to evaluate voltage
performance was performed [p. 140, ls. 12-16].

      On cross-examination by Mrs. Jacobson, Mr. Maliszewski testified that line
losses cannot be prevented. He said they are a natural phenomena. He stated that
whenever current flows in a transmission line the current produces flows through
a resistance, and losses are simply the heating of that resistance or that
transmission line [p. 162, ls. 11-20]. He stated line losses are a natural
consequence of system operation. He stated, whenever power flows from a
transmission line, losses are going to occur [p.
165, ls. 3-9].

      In response to a question from the Court, Mr. Maliszewski stated that
if the merger in its implementation resulted in a definitive overload
condition at the Fort Smith station which did not exist before, then it
appears one solution would be for a reinforcement at Fort Smith [p. 170, ls.
7-11].  Mr. Maliszewski stated in his rebuttal testimony filed on April 12,
1999 (Exhibit 192) that prior to the merger, the Fort Smith transformer does
have a small amount of capacity to accommodate load growth and other system
conditions [Exhibit 192 at p. 22, ls. 18-20].

CRAIG BAKER

      Mr. Craig Baker, Vice - President - Transmission Policy for AEP, testified
on behalf of the Joint Applicants. Mr. Baker's testimony contained in Exhibits
13, 76 and 196 was accepted into the record without objections. Mr. Baker
described the System Integration Agreement (SIA) through which the companies
will integrate their power supply resources, explained the central


                                       28
<PAGE>   37
economic dispatch of the merged company's generating units and the
production-related benefits that will accrue as a result of the post-merger
operations of AEP and CSW.

      The SIA provides for the distribution of power supply costs and benefits
between the two zones, the east zone (presently AEP's system) and the west zone
(presently CSW's system). The existing intra-system agreements will continue to
govern the distribution of costs and benefits within the zones. It is the intent
of the Applicants to centrally dispatch the combined system and eventually to
combine the control area functions of the east and west zones. However,
generation dispatch priorities will be the same as pre-merger, i.e., each zone's
most economic generation will be used to serve its native load and previously
committed firm load contracts.

      Under the SIA, the price in the purchasing zone will be one-half of the
sum of the foregone opportunity cost to sell capacity in the supplier zone and
the decremental capacity purchase cost in the purchasing zone. For example, if
PSO needs to purchase capacity and the price of capacity is $4.00 in the CSW
zone and $2.00 in the AEP zone, PSO would purchase at a price of $3.00 (The
$2.00 AEP zone price plus one-half the difference between the CSW zone price of
$4.00 and the AEP zone price of $2.00). If the situation is reversed, i.e., the
CSW zone price is less than the AEP zone price, then PSO would make the purchase
in the CSW zone since it is cheaper, thereby paying the same price they would
have paid absent the merger. Energy works in the same manner. For energy the
price is the lower of CSW's decremental cost or one-half of the sum of AEP's
out-of-pocket costs and CSW's zone decremental cost.

      Mr. Baker also estimated the production-related benefits and costs
associated with the post-merger operations of the combined company.
Production-related benefits will result from the economic transfer of energy
among the east and west zone companies to displace relatively


                                       29
<PAGE>   38
higher cost generation in one zone with relatively lower cost generation from
the other zone. The net production-related savings are as follows:


<TABLE>
<S>                                             <C>
      Gross Production Savings                  $198 million
      Transmission Wheeling Costs               ($39 million)
      Net Fuel Related Savings                  $159 million)
      Foregone Net Revenue                      ($61 million)
                                                -------------
      Net Production Related Savings            $ 98 million
                                                ============
</TABLE>

According to Mr. Baker, the merger affords the opportunity for
production-related savings through the economic dispatch and transfer of energy
between zones in a real-time manner benefiting CSW's and AEP's customers.

      Mr. Baker submitted rebuttal testimony to respond to the recommendations
of Staff witness Crosslin that Applicants join an Independent System Operator
("ISO"). He also provided documentation related to affiliate purchases of
capacity and energy.

      In response to Mr. Crosslin's recommendation that Applicants be required
to join an ISO at their earliest opportunity to further mitigate transmission
market power concerns, Mr. Baker stated the Applicants are willing to join a
properly organized ISO of large geographic scope with a truly independent
governance structure, broad authority over transmission pricing and reliability,
and appropriate configuration and fair provisions for transmission pricing and
revenue distribution. According to Mr. Baker, AEP has not joined the Midwest ISO
(MISO) because it has a number of flaws including that MISO covers too narrow a
geographic area. The decision of other utilities to the north and east of AEP
not to join MISO undermines the ability of MISO to facilitate access to major
power markets and MISO does not have an efficient pricing mechanism or fair
revenue distribution. AEP is working with a group of utilities, called the
Alliance, to either form a separate ISO or to join a reformed MISO. In Oklahoma,
CSW's has been active in working with the Oklahoma staff and other utilities
toward an ISO in the SPP.


                                       30
<PAGE>   39
      Mr. Baker testified that the Staff's concern that affiliate sales of
capacity or energy under the proposed System Integration Agreement ("SIA") will
cause Oklahoma ratepayers to pay a higher price for electricity than they would
have paid absent the merger was unfounded. The merger will not effect the price
or the need for capacity by PSO, but will afford an additional opportunity for
PSO to purchase AEP capacity.

      Under the SIA, the price in the purchasing zone will be one-half of the
sum of the foregone opportunity cost to sell capacity in the supplier zone and
the decremental capacity purchase cost in the purchasing zone. For example, if
PSO needs to purchase capacity and the price of capacity is $4.00 in the CSW
zone and $2.00 in the AEP zone, PSO would purchase at a price of $3.00 (The
$2.00 AEP zone price plus one-half the difference between the CSW zone price of
$4.00 and the AEP zone price of $2.00). If the situation is reversed, i.e. CSW
zone price is less than the AEP zone price, then PSO would make the purchase in
the CSW zone since it is cheaper, thereby paying the same price they would have
paid absent the merger. Energy works in the same manner. For energy the price is
the lower of CSW's decremental cost or one-half of the sum of AEP's
out-of-pocket costs and the CSW's zone decremental cost.

      Mr. Baker testified that the Applicants are committed to participation in
an Independent System Operator (ISO) or other RTO arrangement. Since April 1998,
AEP has participated in discussions regarding the development of the Alliance
RTO and, as described below, the process is currently expected to lead to a
Federal Energy Regulatory Commission ("FERC") filing this year.

      Beginning July 1, 1998, CSW/Southwest Power Pool ("CSW/SPP") has
participated in the Southwest Power Pool short-term tariff, under which SPP
controls access to the SPP members systems, including the CSW/SPP system, for
short-term transactions. In addition, in


                                       31
<PAGE>   40
December 1998, the SPP filed with the FERC an enhanced regional transmission
tariff, which provides control and access for long-term transmission service.
CSW/SPP has also been an active participant in the development of an SPP-RTO.

      Currently, the SPP has a regional tariff that applies to short-term (less
than a year) transactions. Under that tariff, the SPP determines transmission
access for purposes of those transactions and is directly responsible for
maintaining the node of the SPP.

      RTO membership provides a number of public benefits. Two of the most
important are:

      (1)   further assistance of non-discrimination in the offering of open
            access transmission; and

      (2) the broadening of energy markets.

Applicants' RTO activities are designed to achieve both of these benefits in the
near term.

      In response to a question from the ALJ as to whether his testimony
regarding ISO's/RTO's was tempered by the stipulation, Mr. Baker indicated the
Applicants had committed to join an RTO by a date certain [pp. 15-16].

      In response to cross-examination from Mr. Stewart, Mr. Baker explained
that the System Integration Agreement, which deals with generation production
costs, and the System Transmission Integration Agreement, which deals with
transmission facilities, provide a basis for maintaining the costs and
benefits to each zone within the zone and to share benefits that are achieved
through the merger among the zones [pp. 18-19].  He also testified that these
agreements require FERC approval [p. 20].  Mr. Baker further testified that
as contemplated under the agreement, AEP Service Company would take over the
functions of CSW Service Company after the merger is consummated [p. 22].  He
additionally testified that the applicants would not enter into a transaction
that would impose more costs on PSO's customers [pp. 24-24].


                                       32
<PAGE>   41
      Mr. Baker further testified on cross-examination by Mr. Stewart, that
the System Transmission Integration Agreement and System Integration
Agreement between AEP and CSW are for a term of five years with the ability
for them to roll-over for additional periods unless terminated [p. 18, ls.
5-9 and p. 19, ls. 18-24].  Mr. Baker also testified that it is projected
that PSO will be short of capacity in the years 1999 and 2000 [p. 23, ls.
10-19].  He stated that the shortage that PSO will need to supply would be to
meet the combination of load and reserves requirements [p. 23, ls. 20-25].
Mr. Baker testified that consideration was given by AEP to the losses that
would occur on the Ameren system associated with the transfer of power from
AEP to CSW but AEP did not do an independent loss study with respect to
losses on the CSW system for that transfer [p. 25, ls. 13-25 and p. 26, ls.
1-9].  The analysis that was done held the losses constant in both systems
[p. 26, Ls. 3-4].

      In response to questions from Ms. Jacobson, Mr. Baker testified as to
the relative timelines for FERC approval of ISO/RTO applications [pp. 26-28].

      On re-direct Mr. Baker reiterated that sales to CSW of up to 250 MW
would be required if savings to CSW would result [p. 29].

ROBERT A. SINCLAIR

      Dr. Robert A. Sinclair testified on behalf of the Municipal Electric
Systems of Oklahoma and the Oklahoma Association of Electric Cooperatives to
address economic matters that arise out of the merger between AEP and CSW,
collectively ("the Applicants").

      According to Dr. Sinclair, the basic competitive problem with this merger
lies in two facts. First, both Applicants are large regional utilities with
control over vast generating resources and transmission facilities. Second, the
merger is taking place in a region of the country where generation supply has
become a critical problem whereby generating capacity has not kept up with the
growth in demand and transmission capacity has not been adequately


                                       33
<PAGE>   42
expanded. This has led to drastic price increases as recently as last summer.
These prevailing conditions certainly heighten the competitive impact of the
merger, especially given the large size of both companies and their geographic
location at the northern and southern ends of the Midwest. While Mr. Sinclair's
testimony, as stricken does not contain empirical market share calculations that
would illustrate the competitive impact of the merger, his testimony does
contain a thorough description of the competitive problems that the merger
entails.

      Dr. Sinclair examined a number of market structure variables to assess the
merger's competitive effects. These other variables include: (1) the potential
of the merger to give rise to anticompetitive effects; (2) entry conditions; (3)
efficiencies; and (4) whether one of the firms is likely to exit the market with
its assets because of financial stress. In examining each of these four factors,
the conclusion is that the merger, (1) will facilitate the exercise of
unilateral market power; (2) is likely to enhance conspiratorial market power
and tacit collusion; (3) will create adverse competitive effects related to the
control of the regional transmission system; (4) will create market power that
is not likely to be undercut by free and easy entry; (5) will not create cost
savings that are remarkable by industry standards (and, indeed, evidence
suggests that costs are lower in smaller utilities); and (6) is not initiated to
save one of the merger partners from exiting the market with its assets because
of financial stress. Consequently, the merger would provide the merged entity
with increased market power, unmitigated by other economic factors.

      In addition to his market power analysis, he also analyzed the proposed
mitigation measures and found that they were inadequate. The Applicants propose
two main mitigation measures. The first is to "divest" about 300 MW of capacity
in the SPP and about 150 MW in the Electric Reliability Council of Texas
("ERCOT"). The second measure is a promise not to invoke priority rights (the
AES-TVA priority) affecting transmission usage from power transfers


                                       34
<PAGE>   43
from AEP to CSW. The idea behind both of these measures is an attempt at
diminishing the increased concentration that results from the merger.

      The "divestiture" proposal is supposed to reduce the post-merger
concentration to a level that is comparable to the concentration level
pre-merger. But in addition to being of inadequate magnitude to reduce
concentration to pre-merger levels, the scheme does not really release the
capacity from CSW's control. And the interim measure to make energy sales is
unsatisfactory because such sales are non-firm and, thus, would not be of
sufficient quality to serve retail demands.

      The Applicants promise not to invoke certain priority rights also will not
mitigate the increased concentration resulting from the merger. The basic
competitive problem is that, as a result of the merger, AEP will gain control of
the bulk of low-cost capacity that can be delivered to CSW's SPP ("CSW-SPP")
control area by controlling access to the transmission capacity into CSW-SPP
from the east. Currently, a large number of firms have somewhat equal access to
this transmission capacity. After the merger, because of certain operational
advantages, AEP will be able to gain priority in using the scarce transmission
capacity into CSW from the east. In an effort to alleviate this problem, the
Applicants propose to reduce the priority at which they can make transfers from
AEP to CSW. This measure is not sufficient to ensure the preemption of other
suppliers because the new Company will still have advantages in obtaining
available transmission capacity over other suppliers.

      Dr. Sinclair also rebuts the Applicants' economic analysis. The rebuttal
is in two parts. First, he explains why the market concentration analysis of
Applicants' economic witness Hieronymous is not an adequate basis from which to
draw conclusions about the competitive impact of the merger. Basically, Dr.
Hieronymous did not consider certain important market


                                       35
<PAGE>   44
supply conditions in the Midwest that are likely to have a determinative effect
on market power. The second part of Dr. Sinclair's rebuttal involves an
examination of the mitigation measures proposed by the Applicants. As noted
above, these measures are not sufficient to ameliorate the severe competitive
consequences of the merger.

      Dr. Sinclair's main recommendation is that the merger should not be
approved. However, if it is nonetheless approved, generation divestiture should
be required to address market power problems. Significant amounts of CSW's
generation should be divested to multiple entities in order to address the
market power problems in this case. Along with this, the Commission should
require that the Applicants join a functional, Independent System Operator
("ISO") before the merger is approved.

      On cross-examination by Ms. Jacobson, Dr. Sinclair testified that he
was familiar with FERC Order No. 592 and that his mitigation recommendations
of divestiture and a requirement to join an ISO were consistent with the
requirements of that order.  He also testified on cross-examination by Ms.
Jacobson that Order No. 592 also provides that expansion of the transmission
system could also be a mitigation measure [pp. 37-38].

      On cross-examination by Mr. Downs, Dr. Sinclair testified it was
practically feasible for American Electric Power to deliver power into
Oklahoma but that such power would have to be bundled with ancillary services
in the SPP to assure reliable service [p. 39, ls. 5-14].  It was Dr.
Sinclair's opinion this had not been done in the past because AEP's resources
were committed to serving AEP's retail customers [pp. 39-40].

      Dr. Sinclair testified on cross-examination that he would modify the
delivered price test to take into account anticipated or historical
equilibrium conditions for analyzing the effects of the merger.  When asked
whether such a model left a lot of room for the exercise of judgment or


                                       36
<PAGE>   45
even bias, Dr. Sinclair responded that all economic models require judgment and
there could be bias injected [p. 41, ls. 18-23].

      Dr. Sinclair testified the adjustments he made to the models were in an
attempt to reveal market power [p. 42].

      Dr. Sinclair admitted on cross-examination that the transfer capacity
from the Ameren system under summer peak to CSW is 760 MW [p. 44, ls. 5-11].
He stated that in his model, he used 1,260 MW as an ATC on the Ameren-CSW
path.  Dr. Sinclair stated that this figure had no empirical basis but was
used in an attempt to model transmission conditions, which he expected to
prevail in the future under certain new transmission institutions, such as an
ISO.  Dr. Sinclair stated the level he chose was to test the sensitivity of
the model and was based upon his informed judgment as an economist [pp.
43-45].

      On further cross-examination by Mr. Downs, Dr. Sinclair discussed his
conclusion that, in order to mitigate market power increases that result from
the merger, Applicants should divest 2,000 MW of capacity.  Dr. Sinclair
admitted that 2000 MW was an amount larger than the 1260 MW path from Ameren
to CSW that he expected to be available in the future.  Regarding the
accuracy of his estimates, Dr. Sinclair stated that his recommendation for
divestiture had no empirical basis but it was better over estimate rather
than under estimate [p. 50,Il. 20 - p. 51, 1-8].

      On redirect examination, Dr. Sinclair testified that all economists need
to rely on informed judgment in making an analysis. He further stated that Dr.
Hieronymous delivered price tests required certain judgments be made. He
testified that, in an appendix to his FERC testimony, Dr. Hieronymous argues a
number of points about the methodology to be used in the FERC delivered price
test. Dr. Sinclair stated he applied his informed judgment based upon


                                       37
<PAGE>   46
certain market realities of events which have either transpired in recent months
or that are forecast in the future based on generation supply [pp. 54-55].

      Finally, Dr. Sinclair testified that, he had heard statements that AEP
has not limited itself to the 250 MW firm transfer to the CSW system.  In
fact, Dr. Sinclair said he had heard that Applicants had reserved the right
to apply to the FERC for non-firm transfers above the 250 MW level [p. 56,
ls. 7-12].

MELVIN H. PERKINS, JR.

      Melvin H. Perkins, Jr. was called as the first witness for Oklahoma Gas
and Electric Company ("OG&E").  Mr. Perkins has been employed by OG&E since
1972 in Transmission and distribution engineering and operations.  He is
presently Manager of Operations in the Power Delivery business unit and is
responsible for the OG&E system transmission operations, substation
construction, operations and maintenance and metering.  This includes
responsibility for transmission system security and tariff administration
including compliance with FERC Orders 888 and 889.  Mr. Perkins received a BS
degree in Electrical Engineering from the University of Oklahoma in 1972.
His Responsive Direct Testimony filed on March 29, 1999 (Exhibit 165), and
the summary of his testimony dated April 19, 1999 (Exhibit 212) were accepted
into the record [p. 64, ls. 12-13].

      Mr. Perkins testified that the capability to import power into Oklahoma
will be significantly impacted by the energy transfer proposed in the merger of
American Electric Power Company, Inc. ("AEP") and Central and South West
Corporation ("CSW"). His testimony was offered to show that Available
Transmission Capability ("ATC") is significantly reduced and he urged the
Commission to deny the merger application at this time and to encourage the
Applicants to come forward with a joint planning initiative to restore the
Oklahoma transmission system to pre-merger conditions.


                                       38
<PAGE>   47
      Mr. Perkins testified that the OG&E system is comprised of 4300 miles of
transmission interconnected with other companies at 43 points. The bulk 345kv
system began with joint planning between OG&E and Public Service Company of
Oklahoma ("PSO") and resulted in several joint ownership lines. He stated that
this highly integrated system of transmission facilities relies on close
coordination between utility companies to ensure continued reliability and
market efficiency. He testified that this coordination could include daily
communication regarding maintenance, service restoration, and other issues.

      Mr. Perkins stated that ATC is an indicator of import and export capacity
with each of the companies interconnected with OG&E. Among other factors, ATC
includes a margin for reliability. He said that this reliability margin is
reserved for generation in one transmission area that provides a backup supply
for another area. He stated that ATC is calculated by running complex computer
models of the system. These models contain thousands of transmission system
elements that have information about each element.

      He testified that OG&E has assigned an incorrect rating to one of these
elements, a large power transformer in the OG&E Fort Smith Substation, and that
caused the ATC to be understated. This rating was changed as a result of
reviewing the Applicants' study and the original study was rerun by OG&E
producing results found in Mr. Perkins' pre-filed testimony.

      He testified that these new results actually reflect a higher ATC from
Entergy to OG&E; however, he asserted that the transfer proposed by the
Applicants in this case still significantly lowers ATC values. Mr. Perkins
testified that ATC is lowered by approximately 94% from Entergy to OG&E due to
the proposed transfer. Chart 1 in Mr. Perkins' pre-filed testimony (Exhibit 165,
p. 4) shows that the import capability from Western Resources is lowered by
approximately 73% and the import capability from CSW will be lowered by 65%. One
possible


                                       39
<PAGE>   48
mitigation OG&E identified through the testimony of Mr. Perkins is to upgrade
the Fort Smith Substation transformer at a cost of approximately $10,900,000.
Mr. Perkins testified that with the time limitations under the merger, OG&E did
not make any in-depth investigation to determine if any other upgrade might be a
solution to the problems caused by the transfer of power in accordance with the
merger. [p. 64, ls. 18-23]. He stated that joint planning with OG&E, CSW, and
other transmission owners in the region would be necessary to determine if the
Fort Smith Substation transformer upgrade is the best solution.

      Mr. Perkins testified that OG&E does not expressly oppose the merger but
initiated its intervention for due diligence reasons. He stated that there are
certain conditions created by the merger that are clearly not acceptable and not
in the best interest of Oklahoma customers. He said that OG&E remains ready to
work with the Applicants to determine the extent of necessary mitigation
measures so that the merger can go forward and pre-merger conditions can be
retained. Mr. Perkins said that OG&E requests that the merger application be
denied and that the Applicants be ordered to engage in joint planning with costs
to restore pre-merger conditions to be paid by the Applicants.

      Mr. Perkins testified on cross-examination that the joint planning
requested by OG&E will require the parties to study the problems caused and
agree on a set of parameters for a computer model [p. 65, ls. 14-17 and p.
77, ls. 23, 24] and then look at what mitigation measures are necessary to
restore the pre-merger conditions [p. 78, ls. 3-4].  The computer model must
include the flows that are on the system along with those related to the
merger transaction [p. 78, ls. 12-17].

      On cross-examination, Mr. Perkins admitted that he had no experience in
transmission planning, as distinguished from operations [p. 84, ls. 4-6].  He
did not know what an annual load


                                       40
<PAGE>   49
factor was [p. 82, ls. 20-21]. He stated the head of the OG&E transmission
planning function was probably more knowledgeable about the status of OG&E's
transmission system than he was [p. 9 1, ls. 1-3]. He was not able to testify
regarding the models used by the Southwest Power Pool for its databases in
preparing its own computer model to analyze the transmission system and did not
know how many points of interconnection OG&E had with Entergy [p. 86, ls. 16-19
and p. 91, 1.23 - p. 92, 1.3]. With regard to many of these matters, Mr. Perkins
said that Mr. Kuebeck would be the best person to ask [p. 82, l. 20 - p. 89, l.
20 and p. 94, ls. 1-2].

      Mr. Perkins further stated that OG&E's study showed that there is no
pre-existing condition that would cause congestion on the OG&E system [p. 78,
ls. 23-25 and p. 79, ls. 1-4].

      Mr. Perkins further testified that OG&E had submitted a five-year
transmission construction plan to the Southwest Power Pool and that such plan
did not contemplate any system upgrade designed to address overloads at or in
relation to OG&E's Fort Smith station [p. 86, l. 20 - p. 87, 1. 4]. Mr. Perkins
agreed that the Southwest Power Pool had adopted Coordinated Planning
Procedures, which were an attachment to the SPP Regional Open Access
Transmission Tariff. He explained that under such procedures, the SPP conducts
seasonal assessments of the expected performance of the regional transmission
network and notifies transmission owners of violations of reliability criteria.
It is then the responsibility of the transmission owner either to explain why
the violation finding is not valid or to identify alterations to the
transmission system that would correct the violation. Mr. Perkins agreed that,
under the procedures, the SPP staff would participate in the conduct of studies
needed to study any such violation and that the procedures make provision for
sharing of the costs of a system upgrade among those who benefit from the
upgrade [p. 87, .l 5 - p. 88, l.5].


                                       41
<PAGE>   50
      Mr. Perkins testified that the merger related study conducted by OG&E
showed that the transformer upgrade for the Fort Smith Substation will
resolve the constraints on the OG&E transmission system [p. 107, ls. 21-24,
p. 112, ls. 22-24 and p. 113, ls. 2-4].

      On cross-examination Mr. Perkins admitted that OG&E had posted on the SPP
OASIS a zero Available Transfer Capability for imports from Entergy for the
summer of 1999. He explained that the zero ATC was based on notification from
the SPP that loop flow from transactions by other utilities had impacted OG&E's
import capability. Mr. Perkins stated that the zero ATC posting had been made in
April and that the transactions referred to by the SPP as impacting OG&E did not
include any transfer from AEP to CSW. Mr. Perkins testified that OG&E had
retained an outside consulting firm, PCA, to analyze the impact on OG&E's system
of transfers from AEP to CSW. He further stated that he had seen the results of
PCA's studies but claimed not to be familiar with Table 1 to PCA's study report
and referred all questions about the report to Mr. Kuebeck [p. 99, ls. 12-13 and
p. 101, ls. 7-16].

      Mr. Perkins further testified that, while OMPA and WFEC had firm
transmission reservations on the OG&E system, he did not know how OMPA or
WFEC used those reservations or where their power supply resources were
located.  Mr. Perkins testified that according to OG&E's answers to the
Applicants' data request (Exhibit 213) that OMPA had no firm transmission
reservation of the Entergy system for imports into OG&E's control area [p.
102, l. 11 - p. 105, l. 19].  However, on redirect examination, Mr. Perkins
explained that the Applicants' data request related to "use" of firm
transmissions and does not reflect the reservations that OMPA has on the
system [p. 113, ls. 6-22].

      On redirect examination Mr. Perkins stated that AEP would not be
required to pay for services under the SPP tariff with respect to the merger
transaction [p. 112, ls. 12-14].  He also


                                       42
<PAGE>   51
stated that AEP would not have any financial obligation under the SPP tariff to
pay for upgrades caused by the merger transaction because AEP has not requested
transmission service through the SPP [p. 112, ls. 16-21].

PETER P. KUEBECK

      OG&E's next witness was Peter P. Kuebeck.  Mr. Kuebeck is employed by
OG&E as Supervisor of Transmission Scheduling.  His Responsive Direct
Testimony, filed on March 29, 1999 (Exhibit 164), the volume two of two
volumes, which Mr. Kuebeck sponsored and which contains the work papers
relating to the studies performed by OG&E in this case and was also filed on
March 29, 1999 (Exhibit 168) and the summary of Mr. Kuebeck's testimony, as
redacted, dated April 19, 1999 (Exhibit 214), were accepted into the record
[p. 131, ls. 15-21].

      Mr. Kuebeck testified that Applicants, AEP and CSW propose a multi-year
arrangement by which a large transfer of electric energy will be sent cross
country from Ohio to Texas.  He stated that, this transfer, which he referred
to as the Merger Transaction, involves a vast distance, broadly distributed
flows and impacts across multiple states and control areas.  Mr. Kuebeck
testified that Applicants were asked to perform a transfer study [p. 117, ls.
4 and 5].  The parameters for the study were agreed upon by the parties in
this case and became a part of an Order of this Commission.  Mr. Kuebeck
takes issue with the study performed by the Applicants in the following
respects:

      1. The transmission system study performed by the Applicants demonstrates
that the proposed merger and transfer of 250 megawatts of energy from AEP to
CSW, the Merger Transaction, cannot be accommodated without negatively affecting
import Available Transfer Capability ("ATC") on the existing transmission grid
in Oklahoma. The proposed Merger Transaction will impose a significant
limitation on electric energy import capability to the State of Oklahoma. The
Applicants insist that there is no ATC from Entergy to OG&E, yet conclude


                                       43
<PAGE>   52
that their own transaction along this same path can be accommodated. He
testified, however, that the Applicants' Merger Transaction is the incremental
transaction that takes away virtually all of the ability of the Fort Smith
substation to carry any other imports of power and reduces import capability
across the transmission system serving Oklahoma [p. 117, ls. 16-18].

      2. The studies that Mr. Kuebeck performed with data provided by the
Applicants demonstrate that transfer considerations were overlooked in the
Applicants' study. Specifically, Applicants failed to perform a meaningful
Linear Transfer Analysis by AC solutions, and Applicants ignored the
Transmission Reliability Margin for each studied contingency.

            a. Linear Transfer Analysis is used to determine the level of
      reliable transfer capability from one area to another. The studies Mr.
      Kuebeck performed for OG&E utilized an AC methodology that is inherently
      more accurate than the DC studies used by the Applicants. An AC analysis
      considers transformer tap settings, generator MVAR limits, shunt devices,
      transmission line MVAR loading, and voltage performance of the network.
      Energy transfers across vast distances require complete AC analysis for
      accurate determination of network performance.

            b. Transmission Reliability Margin ("TRM") is that amount of
      transmission capacity used in this region to supply generation resources
      from adjacent utility systems to maintain generation reliability in the
      event of generator forced outages. Applicants failed to consider TRM in
      their analysis. The Applicants failed to recognize the absolute Available
      Transfer Capability at the points of interconnection. The Merger
      Transaction reduces ATC severely at all north and east import points for
      the purchase of energy outside Oklahoma. The Applicants insist that TRM of
      other companies is inconsequential to the AEP to CSW transfer of energy.
      That aside, the Applicants have


                                       44
<PAGE>   53
      reported that there is a decrease in First Contingency Incremental
      Transfer Capability ("FCITC") into OG&E after subtracting the 250 megawatt
      transfer. Applicants' own study shows there is a significant reduction in
      import capability to Oklahoma.

      3. Mr. Kuebeck performed a Loss Study for OG&E using the load flow data
submitted by Applicants. The study revealed increased losses for OG&E as energy
flows on parallel paths through the OG&E system to CSW SPP and CSW ERCOT. Losses
appear as loads to generators, requiring the generators to produce more power
and use more fuel. The additional fuel cost for the losses caused by the Merger
Transaction will be paid for by all OG&E customers. Mr. Hiebsch provides
quantitative cost estimates for this impact in his responsive direct testimony.

      Mr. Kuebeck further testified that Applicants were asked by this
Commission to perform and submit a study that would identify transmission
constraints that might result from this merger. Using the Applicants' data Mr.
Kuebeck performed studies to verify the conclusions reached by the Applicants.
According to Mr. Kuebeck, while all of these studies reflect a decrease in
import capability into the State of Oklahoma as a result of the Merger
Transaction, Applicants suggest that these results should be ignored. Mr.
Kuebeck stated that the studies he performed clearly demonstrate harm to
Oklahoma's electric consumers, and Applicants should propose and agree to
implement mitigation measures that will eliminate that harm.

      Mr. Kuebeck criticizes Applicants for relying too heavily on DC transfer
studies rather than relying on the more accurate AC studies. Out of the
estimated 2,000 to 3,000 cases studied by the Applicants, only 12 of the studies
were done with an AC solution to verify the DC transfer study [p. 128, ls. 17-24
and p. 129, ls. 2-12].


                                       45
<PAGE>   54
      Mr. Kuebeck testified that the OG&E transmission line losses were
calculated using the winter 1999 case provided by the Applicants [p. 129, ls.
16-17].  Although an hour by hour computation of the line losses throughout
the entire year would yield a more precise calculation, Mr. Kuebeck is
comfortable that the figures on the exhibit he sponsored are representative
of what would be the annual loss on OG&E's system [p. 130, ls. 5-20].  He
explained that there are two types of power on OG&E's system negatively
impacted by the merger: real power measured in megawatts [p. 132, Is. 12-23]
and reactive power measured in MVARs [p. 133, ls. 1-8].  Mr. Kuebeck
estimates that the merger will increase line losses on OG&E's transmission
system by 5 megawatts in real power [p. 130, ls. 23-25] and by 44 MVARs of
reactive power [p. 133, ls. 13-17, Exhibit PPK-1].  Mr. Kuebeck explained
that as the transmission system becomes loaded, it is necessary to supply
more capacity MVARs to the system to maintain the voltage [p. 133, ls. 18-24
and p. 134, ln. 2].

      Mr. Kuebeck testified that he is familiar with the SPP coordinated
planning procedures.  The seasonal assessments that the SPP does as
contemplated by those procedures is done to point to violations in
reliability.  Mr. Kuebeck testified that SPP has not advised OG&E that any of
its facilities are in violation of the SPP reliability criteria [p. 153, ls.
5-15].

      In response to cross-examination, Mr. Kuebeck admitted that OG&E's OASIS
postings were at variance with the chart in Mr. Perkins' testimony that
purported to list OG&E's Available Transfer Capabilities for imports from OG&E's
interconnected neighbors. In particular, where Mr. Perkins' chart had shown that
before the AEP/CSW merger OG&E would have an ATC from Entergy of 139 MW the OG&E
OASIS posting showed zero ATC. Mr. Kuebeck testified that Entergy had similarly
posted a zero ATC value for imports into OG&E from Entergy, which Mr. Kuebeck
said was appropriate [p. 142, l 22 - p. 144, l. 21].


                                       46
<PAGE>   55
      Where Mr. Perkins' chart had shown a pre-merger ATC from GRDA. of 417
MW and a post-merger ATC of 392 MW, Mr. Kuebeck stated that the OG&E OASIS
posting showed only 231 MW of ATC available from GRDA. prior to the merger
[p. 144, l. 21 -  p. 145, l. 5].  Mr. Kuebeck further admitted that OG&E's
OASIS postings showed that OG&E had provided for no Transmission Reserve
Margin (TRM) in relation to its import capabilities from any of its
interconnected neighbors other than Entergy [p. 166, l. 13 - p. 167, l. 7].
Mr. Kuebeck testified that he was comfortable with OG&E's OASIS postings [p.
144, l. 21 p. 148, l. 12].

      Mr. Kuebeck also admitted that DC analyses were customarily used to
study the performance of the transmission network under contingency
conditions to expedite the analysis of hundreds of different contingency
conditions and that the study process that Applicants followed in this case
mirrored the process that the Southwest Power Pool ordinarily follows [p.
150, l. 4 p. 151, l. 22].  Mr. Kuebeck agreed that, contrary to his prefiled
testimony, Applicants had performed AC studies to confirm the reasonableness
of their DC studies [p. 128, l. 14 - p. 129, l. 3] and that in all but one
instance the AC results were consistent with the DC results [p. 167, ls.
4-6].

      Mr. Kuebeck agreed that linear load flow analyses involve a systematic
evaluation of the loss of individual bulk power system elements on other
elements of the interconnected network but that his study of the effect of
the AEP to CSW transfer on OG&E's import capabilities was based on an
assessment of only 31 contingencies [p. 155.  Is. 8-12; p. 161, ls. 14-16 and
p. 186, ls. 18-20].  Mr. Kuebeck said that it was important to select the
appropriate outages to study where you know they can make a difference.  It
was for this reason that he studied outages of Fort Smith station because it
has a history of outages including four outages in the last three years.  Mr.
Kuebeck pointed to Fort Smith as an example of where operating judgment and


                                       47
<PAGE>   56
system knowledge helps in selecting the appropriate contingencies to study [p.
154, l. 17 - p. 155, l. 3].

      Mr. Kuebeck admitted that originally if any studies were put forward in
this proceeding by OG&E, PCA would do the studies [p. 160, ls. 8-13].
However, in the last days of March, OG&E decided that it should perform its
own studies [p. 160, ls. 8-13].  Mr. Kuebeck stated that based on the
information provided by OG&E, it was reasonable for the Applicants to assume
that the Fort Smith transformer limit is a pre-existing condition [p. 169,
ls. 14-23].  Mr. Kuebeck admitted that Table 1 to the PCA study showed that
the Fort Smith 161/500 MVA transformer, even when modeled at its correct
emergency rating, overloaded when the Fort Smith 161/345 MVA transformer was
out of service even before the AEP to CSW transaction, but that the SPP had
not informed OG&E of any reliability violation.  Mr. Kuebeck had earlier
corrected his testimony on direct examination by stating that the AEP to CSW
transfer would affect loadings on Fort Smith by less than 5%, not 20% [p.
115, ls. 11-12 and [p. 169, l. 11 - p. 170, l. 10].

      Table 1 to PCA's study report showed that a transmission line on the
Entergy system would be the element that would limit to zero firm power
transfers from Entergy to OG&E [p. 174, ls. 6-16]. When asked about this, Mr.
Kuebeck contended that the consultant's analysis was not reliable because
neither OG&E nor its consultant had confirmed with Entergy that transmission
lines on Entergy's system would actually respond to contingencies as indicated
in the PCA study. Mr. Kuebeck testified that OG&E had made no recent effort to
engage in coordinated planning with Entergy [p. 169, ls. 6-14].

      After rejecting PCA's original results, which were based on a
full-blown contingency analysis which studied the outage of 9000
interconnected system facilities [p. 178, l. 86], PCA was asked to do a
different study.  Mr. Kuebeck explained that the second PCA study produced


                                       48
<PAGE>   57
no equivalent to Table 1 to the first PCA study and that the second study was
based on a different set of transfers and may include different modeling of
generation changes [p. 186, ls. 3-14]. When asked why he had stated in direct
testimony that the PCA studies were consistent with the studies Mr. Kuebeck had
done, Mr. Kuebeck stated that they were generally because they both examined the
effects of the AEP to CSW transfer [p. 191, l. 19 - p. 192, l. 1].

      When asked about the loss study that he had done, Mr. Kuebeck agreed
that he had used a winter season base case prepared by the SPP in January
1998 rather than the SPP base cases that Applicants and OG&E had used for
determining the loop flow effects of the AEP to CSW transfer, which were
prepared by the SPP in December 1998 [p. 193, l. 10 - p. 194, l. 4].  Mr.
Kuebeck agreed that the PCA study, which was based on the Summer 1999 base
case prepared in December 1998, showed that at the summer peak additional
losses resulting from the AEP to CSW transfer would be 3.1 MW not the 5.5 MW
Mr. Kuebeck had found based on the older winter base case [p. 195, ls.
7-21].  Mr. Kuebeck readily admitted that his measure of incremental losses
associated with the AEP to CSW transfer does overstate the amount of
incremental losses that OG&E would experience on an average annual basis [p.
195, l. 23 - p. 196, l. 2].

      Mr. Kuebeck was cross-examined about his Exhibit PPK-3, which shows the
impacts that a number of transactions for which firm transmission
reservations have been made that include service in the month of August 1999
would have on OG&E's Fort Smith station [p. 204, l. 16 - p. 205, l. 17].  Mr.
Kuebeck stated that there were other long-term transactions on this list that
would have an impact on Fort Smith station loadings that would be about the
same or greater than the AEP to CSW transfer [p. 206, l. 1 - p. 209, l. 7].
Mr. Kuebeck further agreed that some of the uses made by Western Farmers and
OMPA of the OG&E system were modeled in the base


                                       49
<PAGE>   58
case and would therefore not be affected by any reduction in ATC resulting from
the merger [p. 211, l. 16 - p. 213, l. 4].

GUSTAVO E. BAMBERGER

      OG&E's next witness was Gustavo E. Bamberger, an economics consultant
from Chicago, Illinois.  Dr. Bamberger is a Principal and Vice President of
Lexecon Inc., an economics consulting firm that specializes in the
application of economics to legal and regulatory issues.  He received a B.A.
degree from Southwestern at Memphis, and M.B.A. and Ph.D. degrees from the
University of Chicago Graduate School of Business.  Responsive Direct
Testimony, filed in this cause on March 29, 1999 (Exhibit 167).  Exhibit 167
and the summary of Dr. Bamberger's testimony, as redacted, dated April 19,
1999 (Exhibit 216), were accepted into the record [p. 13, ls. 5-10].

      Dr. Bamberger testified that Lexecon Inc. had been asked by OG&E to
analyze the likely effect of the proposed merger of AEP and CSW on buyers of
electricity in Oklahoma.  Based on the available evidence, they reached the
following conclusions:

      FIRST, absent additional mitigation measures, the proposed AEP/CSW merger
      likely will harm a substantial number of Oklahoma consumers because it
      will reduce available transmission capacity into Oklahoma from relatively
      low-cost power suppliers.

      SECOND, Applicants' proposed mitigation measures fail to address the
      merger-induced reduction in available transmission into Oklahoma.

      THIRD, Applicants' proposed mitigation measures do not alleviate market
      power concerns.


      Dr. Bamberger testified that the proposed merger reduces transmission into
Oklahoma. He stated that as a condition of the proposed merger, Public Service
of Oklahoma ("PSO"), a CSW company, has entered into transmission service
agreements with Ameren and Western


                                       50
<PAGE>   59
Resources ("the Ameren contract"),
whereby PSO purchased 250 megawatts of firm "point-to-point" transmission
service for the period June 1, 1999 to May 31, 2003. If it were not for the
merger, CSW was not planning to purchase firm energy from AEP; instead, CSW
intended to utilize different transmission resources to reach alternate energy
suppliers. Thus, Dr. Bamberger concluded that this sale is merger related.

      Dr. Bamberger testified that Applicants concede that CSW's use of the
Ameren transmission path will affect the availability of transmission in other
parts of the state because AEP/CSW's use of the Ameren path causes "loop flows"
over other parts of the Oklahoma transmission system. He explained that loop
flows are power flows on portions of a transmission system owned by utilities
that are not involved in a particular power transaction.

      Dr. Bamberger stated that because less transmission will be available as a
result of the merger, certain transactions between Oklahoma utilities and power
suppliers likely will be precluded. That is, if the merger is completed (without
additional mitigation), power purchasers in Oklahoma, like OG&E, will not be
able to import as much power from outside of the state. This reduction in
transmission capability also likely will affect several other entities in
Oklahoma, including the Oklahoma Municipal Power Authority and Western Farmers
Electric Cooperative. In effect, a reduction in the availability of transmission
reduces the geographic size of the market in which an Oklahoma utility can
purchase power, thus reducing OG&E's (and others') ability to import lower-cost
power into Oklahoma. Dr. Bamberger concluded that such a reduction in the
availability of relatively low-cost power harms Oklahoma consumers.

      Dr. Bamberger further testified that Applicants' proposed mitigation
measures do not address the effect of the merger on transmission. He stated that
Applicants concede that the proposed merger raises market power concerns. In
response to these concerns, Applicants


                                       51
<PAGE>   60
propose certain mitigation measures. Dr. Bamberger testified, however, that
Applicants' proposed mitigation measures fail to address the merger-induced
reduction in the geographic size of those markets. That is, even if the proposed
mitigation measures reduce concentration in Oklahoma to the pre-merger level,
they do not return a transmission capability into Oklahoma to the pre-merger
level because the proposed mitigation measures do not affect merger-induced loop
flows. Dr. Bamberger testified that the solution to the merger-induced reduction
in transmission capability is straightforward. It can be mitigated by increasing
transmission capacity at points where the Ameren transaction-related loop flows
would reduce the availability of transmission. Such a mitigation measure would,
in effect, return the geographic size of the market to pre-merger levels.

      Dr. Bamberger testified that because the proposed merger affects the size
of the geographic market, Applicants' use of an "HHI" analysis to evaluate the
effectiveness of the proposed mitigation measures is misleading. Applicants'
analysis consists of comparing pre-merger HHIs in particular geographic markets
to post-merger HHIs in smaller geographic markets. In Dr. Bamberger's opinion,
Applicants' economic analysis is flawed because the pre-merger and post-merger
HHIs are based on markets of different geographic sizes.

      Dr. Bamberger testified that Applicants' proposed mitigation measures do
not alleviate market power concerns. He said that even if the pre-merger extent
of the geographic market were re-established by upgrading transmission capacity
to offset merger-induced loop flows, Applicants' mitigation measures do not
alleviate concerns that the merger will allow a merged AEP/CSW to exercise
market power. Dr. Bamberger stated that Applicants claim that they will mitigate
market power concerns in Oklahoma by divesting generation assets. In particular,


                                       52
<PAGE>   61
Applicants claim that they will "divest" 300 megawatts of generating capacity
from PSO's Northeastern plant (which has a total generating capacity of about
1,500 megawatts).

      Dr. Bamberger stated that in general, divestiture can be a reasonable
approach for mitigating market power concerns (but not loop flow concerns)
because it removes the divested assets from the control of the merging parties.
However, Applicants' mitigation proposal falls short of divestiture. First,
Applicants concede that their proposed "divestiture" will not take place until
sometime after July 1, 2002. Indeed, AEP and PSO have not committed to divest
generation assets by any particular point in time. Second, the "divestiture"
fails to eliminate AEP/CSW's control of the "divested" asset. In particular,
AEP/CSW likely will be able to influence when outages will be scheduled at the
"divested" plant.

      Dr. Bamberger stated that if AEP/CSW can override the objections of the
owners of the "divested" 300 megawatts (or if they do not object), AEP/CSW could
use its control of the Northeastern plant to exercise market power by
restricting the output of the Northeastern plant at times when such a reduction
in output could substantially raise electricity prices. It is Dr. Bamberger's
opinion that the proposed mitigation measures may make it easier for AEP/CSW to
exercise market power because it may allow the merged firm to raise market price
by restricting the output of the "divested" 300 megawatts of generating capacity
at no cost to AEP/CSW.

      Dr. Bamberger testified that under Applicants' proposed interim mitigation
measures, that is, until the proposed "divestiture" of 300 megawatts takes
place, CSW will conduct interim system energy sales from the Northeastern plant
at a specified price. It is his understanding that under the terms of the
proposed sales contracts, CSW will be able to recall the energy under certain
"emergency" conditions. If it does so, CSW will be obligated to compensate the
owners of the energy, at a yet-to-be specified amount.


                                       53
<PAGE>   62
      It is Dr. Bamberger's opinion that this interim mitigation measure fails
to alleviate market power concerns. First, the merged firm will maintain
operational control of the to-be-divested plant during the interim period. As
stated in Dr. Bamberger's testimony, Applicants may have an incentive to
exercise market power by scheduling outages strategically. Second, if the amount
of compensation that CSW must pay to the owners of the financially firm energy
in the event of a recall is not related to the price of energy at that time, CSW
may have an incentive to recall the energy, thereby profiting from the
difference between market price and the amount it must pay to compensate the
owners of the financially firm energy.

      Dr. Bamberger testified further that even if his concerns about the
proposed mitigation measures were unfounded, Applicants concede that their
proposed mitigation measures fail to prevent concentration levels from
increasing substantially in several areas of Oklahoma, including OG&E's service
area. That is, Applicants concede that, as a result of the proposed merger,
concentration in several areas of Oklahoma will increase substantially.

      Dr. Bamberger testified that OG&E's concerns about the availability of
relatively low cost power as a consequence of the merger are not overstated,
contrary to the criticisms of the Applicants' consultant, Dr. Hieronymous.
Dr. Bamberger noted, first of all, that Dr. Hieronymous did not deny that the
merger would have an effect on such availability but only claimed that the
effect would be relatively small.  Dr. Bamberger testified that there is not
any reason to believe that the effect will be small.  He testified that the
effects will likely increase into the future [p. 11, ls. 22-25 and p. 12, ls.
1-11].

      Dr. Bamberger testified that the merger would harm the 60 cities
represented by the Municipal Electric Systems of Oklahoma because it will
cause a reduction in import capability [p. 13, ls. 14-24].  Dr. Bamberger
compared this situation to a quota on the import of low priced


                                       54
<PAGE>   63
cars. He stated that what the loop flows, in effect, do is reduce the
availability of transmission and that is like a quota on relatively low cost
power. He stated that being denied access to some of this low cost power,
because of the loop flows, harms anybody who would have an opportunity to buy
such relatively low cost power [p. 13, l. 25 and p. 14, ls. 1-10].

      Dr. Bamberger testified that the Applicants' plan of divestiture under
their mitigation measures has nothing to do with the reduction of
transmission and how that would increase costs to Oklahoma consumers [p. 16,
ls. 9-22 and p. 17, ls. 4-9].  Dr. Bamberger also stated that some of the
terms relating to the proposed mitigation measures are ambiguous, for
example, the price that the owners of the financially firm energy will get
making it difficult for an economist to be able to evaluate the effectiveness
of the measure [p. 12, ls. 18-24 and p. 17, ls. 10-15].

      Under cross-examination, Dr. Bamberger testified that he did not make
an independent evaluation of the impact of the on transmission capability and
that he was not competent to perform loop flow studies.  Dr. Bamberger noted,
however, that both Mr. Maliszewski and Dr. Hieronymous found that the merger
caused negative impacts on import capability.  Dr. Bamberger observed that
the Appendix A analysis (under the FERC Merger Policy Statement) done by Dr.
Hieronymous showed that the amount of power that can be imported into the
OG&E service area is reduced [p. 19, ls. 12-25 and p. 20, ls. 1-10].  Dr.
Bamberger also testified that he relied upon OG&E's engineering studies which
show that loop flows would reduce transmission and Mr. Maliszewski's studies
which showed the same thing, so he did not do any additional investigation
beyond noting that both sides agree [p. 20, ls. 12-25 and p. 21, ls. 1-2].
Although the Applicants and OG&E disagree as to the extent transmission
capabilities are reduced, Dr. Bamberger found the parties' agreement to be
significant [p. 25, ls. 18-25 and p. 26, ls 1-20].


                                       55
<PAGE>   64
      Dr. Bamberger concluded that the effect of the merger on the
availability of transmission will likely increase the cost of electricity to
a substantial number of customers.  This conclusion was based on his
observation that absent the merger, CSW would utilize different transmission
resources to reach alternative energy suppliers and that AEP was unlikely to
be a supplier in Oklahoma and Texas in the future because it has more
lucrative opportunities elsewhere [p. 27, is. 2-12, 23-25 and p. 28, ls.
14-17].  Dr. Bamberger cites the testimony of Mr. Maliszewski and Dr.
Hieronymous to support this conclusion [p. 28, ls. 8-25 and p. 29, ls. 1-6].
Dr. Bamberger concludes that the Oklahoma Municipal Power Authority and
Western Farmers Electric Cooperative will be affected by the merger-induced
reductions in transmission capability because they rely on the transmission
system of OG&E [p. 31, ls. 11-18].  He reaches this understanding in reliance
on the testimony of Mr. Hiebsch without independent knowledge of the facts
[p. 31, ls. 19-25 and p. 32, l. 4].

      On further cross-examination, Dr. Bamberger was advised that
Applicants' interim mitigation measures include a sale of energy from CSW's
system, not just from the Northeastern plant, as Dr. Bamberger had
testified.  However, Dr. Bamberger stated that that fact did not make a
difference in his opinions [p. 35, ls. 3-19].

STEPHEN F. HIEBSCH

      The final witness called on behalf of OG&E was Stephen F. Hiebsch. Mr.
Hiebsch is the manager of Market Solutions for OG&E which is the research and
service support group of the Marketing and Customer Care Division. Market
Solutions contains traditional areas such as cost of service, revenue needs,
rate making, electric forecasting for both retail and wholesale, and load
research. It also includes areas such as customer research, financial analysis
and market studies. Mr. Hiebsch earned his B.S. degree in business and
mathematics from Southwestern College in Winfield, Kansas. He did graduate work
at Wichita State University in Wichita,


                                       56
<PAGE>   65
Kansas, and earned a Master's Degree in Economics from Oklahoma State
University. He has also completed an additional 30 hours of graduate courses in
economics from Oklahoma State University. Mr. Hiebsch has previously been
recognized as an expert witness before this Commission in the areas of economic
forecasts, economic analysis, financial analysis and costs of capital. His
Responsive Direct Testimony, filed on March 29, 1999 (Exhibit 166), and the
summary of his testimony dated April 19, 1999 (Exhibit 217), were accepted into
the record [p. 47, l. 19].

      Mr. Hiebsch testified that the purpose of his testimony was to identify
the concerns that OG&E has with the proposed merger of AEP and CSW, and its
subsidiary, PSO, from a competitive and ratepayer impact perspective, and the
relief OG&E seeks from the Commission. He stated that OG&E is concerned that the
merger of AEP and CSW, as structured with their proposed mitigation measures,
will constrict both the number of energy suppliers and the extent to which
energy suppliers are able to participate in the Oklahoma marketplace. He
testified that this reduction in marketplace participants has the likely effect
of raising electric prices by limiting competition.

      Mr. Hiebsch stated it was his understanding that this merger will be
approved automatically if the Commission does not affirmatively reject the
merger in the time permitted under Oklahoma law. He said it was also his
understanding that under Oklahoma law, the Commission should disapprove the
merger if the effect of the merger substantially lessens competition in the
furnishing of public utility service in this State. He stated that under the
conditions that will prevail in the post-merger world, based upon Applicants'
filings and OG&E's review of those filings, it leads OG&E to believe that this
merger will have a significant adverse impact on competition in Oklahoma.
Furthermore, any savings which might be achieved for


                                       57
<PAGE>   66
PSO's Oklahoma customers comes at the expense of customers of the remaining
electric providers in this State.

      Mr. Hiebsch stated that he believes the mitigation measures of the
Applicants may never occur since they are based upon Applicants' own subjective
determinations of their need for capacity. He also feels that the divestiture of
300 megawatts of capacity is likely to never occur since growth in load of this
size could occur in a short period of time. Mr. Hiebsch testified that there is
evidence in the record that PSO is already short of capacity, referring to
Exhibit SFH-3 to his Responsive Direct Testimony (Exhibit 166).

      Mr. Hiebsch testified that historically OG&E has had the ability to
purchase power off-system for economic reasons. As an example, he stated that
the Fort Smith substation is the primary interconnect to OG&E for power coming
from the East. In his prefiled testimony, he discussed the various reasons for
purchasing power from off system suppliers. He testified that while historically
these amounts have not been large, with the changing competitive environment,
economy power purchases will increase. He testified that Exhibit SFH-8 to his
Responsive Direct Testimony (Exhibit 166) is an example of historic capabilities
but is not an indication of the expected growth that is likely to occur. Mr.
Hiebsch referred to Mr. Perkins' chart which shows OG&E's entire system is
impacted by the 250 megawatts transfer. He stated that in addition to the
Entergy interconnection (Fort Smith substation), major interconnection
capabilities with SPA, Western Resources and CSW are also significantly reduced.

      Mr. Hiebsch stated that these increased system wide transmission
constraints substantially lessen competition in Oklahoma after the merger. The
constraints remove the opportunity to make economic power purchases on behalf of
Oklahoma consumers. Also,


                                       58
<PAGE>   67
Economic Development will be hurt by the increased transmission constraints
which limit competition.

      Mr. Hiebsch also stated that these constraints hurt more than just OG&E's
customers. Cooperative Association members served by Western Farmers and
municipal customers served by the Oklahoma Municipal Power Authority, likewise,
will be hurt. He said that consumers throughout the State of Oklahoma will be
affected by this reduction in import capabilities. The increased transmission
constraints limit the geographic size of the marketplace which decreases the
opportunity for obtaining purchased energy at a competitive price. Mr. Hiebsch
concludes that this hurts all Oklahoma customers.

      Mr. Hiebsch stated that another negative impact of the merger is the
increased transmission line losses as testified to in Mr. Kuebeck's testimony.
Mr. Hiebsch testified that these increased line losses cause OG&E's Oklahoma
retail and wholesale customers to pay approximately $1.5 million per year more
in fuel costs as shown in Exhibit SFH-9 to his Responsive Direct Testimony
(Exhibit 166). He stated that in CSW's Proxy Statement, March 5, 1999, which is
Exhibit SFH-10 to his testimony (Exhibit 166), the Applicants claim that the PSO
customers will receive an $11.8 million fuel cost savings over the next 10
years. By multiplying the annual increased fuel expenditure by 10, the estimated
cost to OG&E's Oklahoma retail and wholesale customers attributable to line
losses is $15 million over 10 years. Thus, he concludes OG&E's customers are
subsidizing PSO's customers. He stated that this does not address any impact
that might be placed on transmission systems other than OG&E's.

      Mr. Hiebsch testified that OG&E's requested litigation measures are as
follows:

      1. The Applicants must bear all capital expenditures necessary to return
the transmission system and the Fort Smith Substation to the pre-merger
conditions. He stated that


                                       59
<PAGE>   68
the preliminary estimate of this expenditure according to Mr. Perkins is
approximately $11 million.

      2. The Applicants must bear all expenditures necessary to install the
equipment required to correct power factor,

      3. Applicants should pay the increased $15 million in fuel costs that is
related to increased line losses.

      4. Contrary to past practice between PSO and OG&E, there was no effort on
the part of the Applicants to conduct any joint planning for future operations.
Since OG&E was not fully informed of the Applicants' plans, any conclusions
drawn thus far must be considered preliminary. OG&E requests that the Applicants
engage in joint planning with the other electric providers in the State to more
fully understand the impacts of the merger and resulting operations will have on
the State. Furthermore, OG&E requests that the Applicants and the other electric
providers in the State work together to resolve issues and problems that arise
from this joint planning.

      Mr. Hiebsch testified that OG&E and its customers must be held harmless
from any required capital investments and increased operating costs caused by
post-merger operations. He stated that OG&E urges the Commission to dismiss the
Application at this time.

      Mr. Hiebsch testified that notwithstanding the comments of Dr.
Hieronymous, OG&E's purchases of power at the Entergy interconnect during the
summers of 1996, 1997 and 1998, which is depicted on Exhibit SFH-8 (Exhibit 166)
does not overstate the amount of purchases that OG&E makes through the Entergy
system. He stated that the path for the energy was actually reserved and payment
for the energy was made and, at the time the power was to flow to OG&E, a
determination was made, based on weather and other factors, whether OG&E needed


                                       60
<PAGE>   69
the power or would sell the power to other entities [p. 45, ls. 16-25 and p. 46,
ls. 1-22]. On cross-examination, Mr. Hiebsch testified that Exhibit SFH-8 was
introduced to show that there are availabilities to purchase energy off-system
through the Fort Smith Substation for OG&E to buy economy purchases of energy so
it can lower costs to its customers. He also stated the purpose was to show that
this type of trading has gone on in the past and as the competitive environment
grows in the future, these purchases could become much larger [p. 55, ls.
14-24]. Mr. Hiebsch testified that the megawatt hours listed on his exhibit for
the days of May in 1998 showed instances where actual physical delivery of
energy was made. However, he could not testify as to which of the megawatt hours
for the month of May in 1998, if any, were actually delivered to OG&E [p. 56,
ls. 5-20].

      On cross-examination, Mr. Hiebsch admitted that he had assumed that in
each hour of the year additional losses caused by transfers from AEP to CSW
would be equal to the losses Mr. Kuebeck had calculated that OG&E would
experience at the hour of the winter peak on OG&E's system [p. 61, l. 21 - p.
62, l. 13].  Mr. Hiebsch further admitted that he had determined the cost of
additional losses caused by a 250 MW transfer from AEP to CSW by assuming
that OG&E would burn additional natural gas to make up for such losses [p.
61. l. 2 - p. 63, l. 16].  Mr. Hiebsch testified that OG&E's average annual
fuel cost was approximately 52% of its average annual gas cost for generating
electricity [p. 60, ls. 1-5].  Mr. Hiebsch testified that he had concluded
that the merger would cause OG&E to incur additional losses at a cost of $15
million over the first ten years after consummation of the AEP/CSW merger by
multiplying an annual cost of $1.5 million, by 10 years.  Mr. Hiebsch
testified that Applicants have planned to transfer power from AEP to CSW for
the length of the contract [p. 63, ls. 1-25].

JIMMY D. CROSSLIN

      Mr. Jimmy D. Crosslin, Tariff and Cost of Service Coordinator for PUD,
testified on behalf of Staff.  Mr. Crosslin testified in support of the
Stipulation, Exhibit No. 209, which was presented to the Court and accepted
into the record in this Cause on April 19, 1999.  Mr. Crosslin testified that
the terms of the Stipulation are a fair compromise and asked the Commission
to accept the Stipulation, as a balance of all interests involved.  Mr.
Crosslin testified that the Stipulation is fair, just and reasonable, as to
the issues it addresses.

      Mr. Crosslin testified that the Public Utility Division also gave serious
consideration, in its review of the Applicants' proposed merger, to the impact
it may have on competition in Oklahoma, and the effect it will have on Oklahoma
jurisdictional ratepayers.

      Mr. Crosslin testified that the regulatory plan as initially proposed by
the Applicants should be rejected, and stated Staff has developed an alternative
plan. Staff recommends that the regulatory plan ultimately approved by the
Commission provide meaningful benefits to the ratepayers and that to accomplish
this goal, Staff proposes the merger savings be credited against the customer's
bill. Mr. Crosslin testified that Staff's proposal provides for a fair and
expedient manner to flow the merger savings to ratepayers. Mr. Crosslin
testified that he recommends a five-year regulatory plan be adopted to address
the regulatory treatment of merger synergies and the cost to achieve the
synergies. Mr. Crosslin testified Staff further recommends that each year
following the merger closing, the Joint Applicants distribute 50% of the
jurisdictional merger synergies to the ratepayers as shown on Attachment A of
the December 19, 1998 prefiled testimony of Jimmy D. Crosslin. Mr. Crosslin
testified that Staff's plan allows for the customers to receive a merger synergy
credit each August following the merger approval date. Mr. Crosslin testified
that the merger synergy credit rider should be effective until such time as the
Applicants' base rates are adjusted through a general base rate filing. Mr.
Crosslin testified that


                                       62
<PAGE>   71
Staff also recommends hold harmless conditions to ensure that the ratepayers are
shielded from unknown and unintended consequences. Attachment B, of Jimmy D.
Crosslin's December 19, 1998 Testimony, provides Staff's overall regulatory plan
recommendations.

      Mr. Crosslin testified the Applicants propose that merger savings be
credited against regulatory assets. However, Staff notes that PSO's regulatory
assets were definitively addressed in PSO's last rate proceeding, Cause No. PUD
960000214. Next, the Applicants propose the merger savings be applied to
depreciation expense to provide the benefit of a lower ratebase for distribution
facilities. Mr. Crosslin testified that Staff cannot support the Applicants'
proposal since it does not provide meaningful benefits to customers.

      Mr. Crosslin testified as to the Applicants' retail market power study and
the load flow study. Mr. Crosslin testified that the proposed merger
substantially lessens competition in a retail access environment. He stated that
the Applicants propose market power mitigation measures in order to gain
regulatory approval of their proposed merger. Mr. Crosslin further testified
that the issue of market power becomes a major and vital concern as the State of
Oklahoma moves toward allowing competition for electric utility services.

      Mr. Crosslin testified that the proposed merger creates market barriers on
the transmission system. The proposed merger contemplates transactions from the
AEP service territory to CSW. Historically, there have been no trading
transactions between the merging parties. Mr. Crosslin testified that the
proposed merger seeks to combine separate, distinct, geographic markets through
a 250 MW transmission service reservation. Mr. Crosslin testified that the
Applicants' reservation for transmission service results in additional
congestion on the regional transmission grid. Mr. Crosslin testified that the
Applicants' transmission reservation limits market participants' ability to
enter the Oklahoma market, which has an impact on the


                                       63
<PAGE>   72
competitiveness of the market. Staff's specific recommendations regarding the
market power issues and hold harmless conditions are provided in the
recommendation portion of Mr. Crosslin's testimony.

      Furthermore, 17 O.S. Section 191.5 provides that the merger may be
disallowed if the Commission finds:

      the effect of the merger or other acquisition or control would be
      substantially to lessen competition in the furnishing of public utility
      service in this state;

      Mr. Crosslin testified that the proposed merger presents competitive
concerns in a retail access environment.  Staff recommended the following
changes to the Applicants' market power mitigation proposal:

      1.    The Applicants shall divest generation assets as necessary to
            address horizontal and vertical market power concerns.

      2.    The Applicants must provide meaningful hold harmless provisions to
            ensure that the customer is not negatively impacted by the merger.
            To date, the Applicants have not provided a meaningful hold harmless
            mechanism to evaluate the opportunity cost of the customers
            resulting from diverting cheap generation as part of the interim and
            divestiture market power mitigation sale.

      3.    The Applicants shall hold the customers harmless for the cost
            differential of coal versus natural gas generation resulting from
            the market power mitigation plan. The Applicants propose to divest
            coal generation capacity instead of natural gas. Staff recommends
            the customer be insulated from the adverse effect that might result
            from the __________.


                                       64
<PAGE>   73
      4.    plan for sharing the generation divestiture gains with the
            ratepayers.

      5.    Applicants should agree to a 75% - 25% sharing of the interim
            generation sale margins.

      6.    The Applicants load flow study of the transmission system identifies
            the congestion areas, which has an impact on the performance of
            Oklahoma transmission systems. Staff recommends the Applicants bear
            the cost of upgrading the Fort Smith transformers.

      7.    Finally, Staff recommends the Applicants join an ISO by a date
            certain to ensure that the transmission system is operated.

      Mr. Crosslin's prefiled testimony was accepted into the record as
Exhibit Numbers 56, 112 and 172, without objection.  Mr. Crosslin testified,
under cross-examination, that it was his understanding that his testimony
should be deemed conformed to be in compliance with the stipulation entered
into on April 19, 1999.  Mr. Crosslin further testified under
cross-examination that an Independent System Operator ("ISO") could identify
and take remedial action to remove transmission congestion and constraints
through regional transmission planning [p. 84 ls. 16-21], and further stated
that PSO, in the offered stipulation, agrees to participate in an ISO
pursuant to the Stipulation at page 11, paragraph 17 (Exhibit 209 attached
hereto).  Mr. Crosslin further testified it was his understanding that the
PSO customers will receive 100 percent of the jurisdictional fuel and
purchase power savings resulting from the merger.  Mr. Crosslin testified
that the upgrade to the transformer at the Fort Smith junction is required by
the Public Utility Holding Company Act, under the interconnection
requirement.  Therefore, the expense to upgrade the transformer is an
appropriate merger cost.  Mr. Crosslin testified that the upgrade is


                                       65
<PAGE>   74
necessary to ensure the parties are returned to pre-merger condition [p.86 ls.
12-17]. Mr. Crosslin testified that this is a traditional issue, because
ideally, the members of an ISO would pay proportionately for this benefit, but
he admitted "we are not there" [p.87 ls. 18-24]. He also testified that the
reason the upgrade is needed is the merger transaction [p.87 ls. 24 and 25 and
p. 88 l. 1) [See also p. 88 ls. 23-25 and p. 89 ls. 1-3].

      Mr. Crosslin was aware that a firm reservation of 250 MW had not been
made for the summer of 1999, and therefore there was not a requirement to
resolve this issue immediately [p. 89, ls. 4-14].

      Mr. Crosslin further reiterated his recommendation was that the
Applicants be required to have the Southwest Power Pool perform a regional
study to identify whether the merger would cause transmission constraints
that may have a negative impact on Oklahoma utilities.  The second
recommendation was for the Applicants to be required to join an ISO. [p. 90,
ls.  1-5 ]

      It was Mr. Crosslin's opinion that this issue would be resolved if the
Southwest Power Pool would in fact do the study, determine if the 250 MW
transfer can be performed and determine what the impact was on Oklahoma
utilities. The parties should be required to accept the decision rendered by the
Southwest Power Pool in this regard [p. 90, ls. 7-12].

      Mr. Crosslin was also aware that PSO could accept the position taken by
the Staff [p. 90, ls. 13-15].

      Mr. Crosslin was also aware that the State of Arkansas in their
approval of the merger had made as a condition that if SWEPCO intended on
leaving the Southwest Power Pool they would come back and request the
Arkansas Public Service Commission for approval [p. 90, ls. 17-22].

KENNETH R. ZIMMERMAN

      Kenneth R. Zimmerman, Ph.D., Tariff & Cost of Service Coordinator for PUD,
testified on behalf of Staff. Dr. Zimmerman testified that this application has
been evaluated by Staff in terms of the criteria contained in 17 O.S., Section
191.5, as well as the general definitions and standards in Sections 191.1
through 191.13. Section 191.5(A), provides:

      The Corporation Commission shall approve any merger or other acquisition
      of control referred to in Section 2 of this act unless, after a public
      hearing thereon, it finds that one or more of the following conditions
      will exist if such merger or other acquisition of control is consummated,
      in which event it shall disapprove such merger or acquisition of control
      and the same shall not be consummated.

The specific criteria in Section 191.5 are:

      1. The acquisition of control would adversely affect the contractual
      obligations of the domestic public utility or of any person controlling
      such domestic public utility, or its ability or commitment to continue to
      render the same level of service to its customers that the domestic public
      utility is currently rendering;

      2. The effect of the merger or other acquisition of control would be
      substantially to lessen competition in the furnishing of public utility
      service in this state;

      3. The financial condition of any acquiring party is such as might
      jeopardize the financial stability of the domestic public utility or any
      person controlling such domestic public utility or otherwise prejudice the
      interest of the domestic public utility's customers;

      4. The plans or proposals which an acquiring party has to liquidate the
      public utility or any such controlling person, sell its assets, or a
      substantial part thereof, or consolidate or merge it with any person, or
      to make any other material change in its investment policy, business or
      corporate structure or management, would be detrimental to the customers
      of the domestic public utility and not in the public interest; or

      5. The competence, experience and integrity of those persons who would
      control the operation of the domestic public utility are such that it
      would not be in the interest of its customers and the public to permit the
      merger or other acquisition of control.

      Dr. Zimmerman testified that his testimony concerns two criteria in the
review Staff performed in assessing the impact of the proposed merger.  In
addressing these criteria, Dr. Zimmerman testified that he focused on the
following:


                                       67
<PAGE>   76
      1. The PROMOD analyses performed by the applicants to assess the
      operational costs and characteristics of the combined AEP/CSW generation
      and transmission systems; and,

      2. The economic impact of the proposed merger on the Tulsa Metropolitan
      Statistical Area (MSA) economy and the Oklahoma economy.

      Based on its review of the data and information provided by the Applicants
and independent analysis, Dr. Zimmerman testified that Staff has reached the
following overall conclusions:

      1. The PROMOD analyses prepared by the Applicants indicate that the AEP
      and CSW generation and transmission systems can be operated in combination
      without significant negative impact on either the reliability or cost of
      power for the customers of PSO;

      2. The PROMOD analyses prepared by the Applicants do not investigate how
      the AEP and CSW generation and transmission systems might be operated so
      as to minimize the cost of power to PSO's customers;

      3. The economic impact of the proposed merger on the economy of the Tulsa
      MSA and the economy of the State of Oklahoma is unknown at this time, and
      for the next 3-5 years; and,

      4. An appropriate and acceptable estimate of the impact of the proposed
      merger on the economy of the Tulsa MSA and the economy of the State of
      Oklahoma can be made by either the University of Oklahoma or Oklahoma
      State University, using state level economic modeling tools already
      available to those institutions.

      Based on these conclusions, Dr. Zimmerman testified that Staff recommends
the Commission approve the proposed merger only if the hold harmless provisions
outlined in Mr. Crosslin's testimony are agreed to by the Applicants. Dr.
Zimmerman testified that these hold harmless provisions are essential to protect
the public interest relative to a proposed merger that has so many uncertainties
and potential impacts for Oklahoma. In addition, Staff recommends that the
Commission order the Applicants to:

      1. Perform more extensive PROMOD analyses to assess any possible
      operational benefits of the merger for PSO's customers; and,


                                       68
<PAGE>   77
      2. Perform ongoing analyses to assess the impact of the merger on the
      economy of Tulsa MSA and the State, in conjunction with the University of
      Oklahoma or Oklahoma State University if possible.

      Dr. Zimmerman testified in an in camera proceeding on April 21, 1999, that
the Applicants voluntarily had Oklahoma State University perform an analysis to
assess the impact of the merger on the economy of Tulsa County, Oklahoma. He
further testified regarding the results of the analysis. Dr. Zimmerman's
testimony presented in the in camera proceeding on April 21, 1999, is under
seal. His conclusions, however, are that additional PROMOD analyses are not
needed due to information received in discovery. The economic impact of the
merger is not fully known at this time. However, even a worst case scenario
would not be a significant adverse economic impact on Tulsa County, considering
the size of Tulsa County economy. Dr. Zimmerman's pre-filed testimony was
accepted into the record as Exhibit Number 59 without objection or
cross-examination.

                   FINDINGS OF FACT AND CONCLUSIONS OF LAW

      The ALJ finds that this Commission has jurisdiction over the merger
pursuant to 17 O.S. Section 191.1 et seq. and OAC 165:5-7-57. Further, the ALJ
finds this Commission has jurisdiction over Public Service Company of Oklahoma
regarding retail rates and the effect that the merger might have on those rates
pursuant to 17 O.S. Section 152, 153 and Okla. Const. Art. 9, Section 18.

      The conditions for disapproval of a merger are set forth at 17 O.S.
Section 191.5, and require the merger be approved unless one of the conditions
contained within the statute would exist if the merger is consummated. The
Stipulation reached by the Joint Applicants, Staff, CSD, and the AG, which sets
forth various hold harmless provisions, guaranteed rate reductions, guaranteed a
base rate increase moratorium, quality of service standards and a most favored
nations clause, satisfies the majority of the statutory standards. The primary
areas of inquiry raised by Intervenor OG&E and others, relating to whether the
merger would lessen competition


                                       69
<PAGE>   78
in the furnishing of public utility service in the state, is negated by the
Joint Applicants' commitment to engage in joint planning and the involvement of
the Southwest Power Pool.

      The evidence tends to show that market power will indeed be impacted in
Oklahoma and competition harmed because of the impact of the merger on the
transmission system at the Ft. Smith transformer which may result in line losses
and congestion.

      The evidence also tends to show that the Southwest Power Pool did not list
this area of transmission (OG&E's Ft. Smith transformer) as a problem in its
seasonal studies and OG&E has no plans for any upgrades for the next five years.

      The ALJ further finds that the Commission should direct PSO and OG&E to
request the Southwest Power Pool to evaluate and identify the impact on the
transmission import capability into Oklahoma at the Ft. Smith 161/500 MCA
Transformer of the 250 MW transfer of power from AEP to CSW across the Ameren
system and to identify what, if any, corrective action should be taken to return
the Oklahoma transmission system to pre-merger condition.

      The ALJ further finds that the Commission should require that, after the
Southwest Power Pool has made its determination, the Joint Applicants be
required to reimburse OG&E for the proportionate share that the Joint Applicants
contribute to any problem found to exist on the Oklahoma transmission system by
making such transfers recognizing that some part of the problems caused by the
merger already exist at the Ft. Smith substation that has resulted in outages
and congestion.

      The ALJ further finds that authority over the alleged line loss issue lies
with the Federal Energy Regulatory Commission.

<PAGE>   79
                                 RECOMMENDATION

      After careful consideration of the testimony and the Stipulation, the ALJ
recommends that the Commission issue an order approving the merger based upon
the conditions set forth herein:

      The ALJ further recommends that the Commission issue an order approving
the Stipulation as being fair, just and reasonable.

      The ALJ further recommends that the Commission direct PSO and OG&E to
request the Southwest Power Pool to evaluate the impact on OG&E's Fort Smith
161/500 MVA transformer of a 250 MW transfer of power from AEP to CSW across the
Ameren system and identify what, if any, corrective action should be taken.

      The ALJ further recommends that the Commission require that, after the
Southwest Power Pool has made its determination, the Joint Applicants be
required to reimburse OG&E for the proportionate share that the Joint Applicants
contribute to any problem found to exist at the Fort Smith substation by making
such transfers, recognizing that a problem already exists at the Fort Smith
substation that has resulted in outages and congestion.

      The ALJ further recommends that the Commission direct the Joint Applicants
to report the results of the Southwest Power Pool evaluation to the Director of
the Public Utility Division of the Oklahoma Corporation Commission no later than
June 14, 1999.

      The ALJ further recommends that the Commission issue an order stating that
the Commission lacks jurisdiction to address the question of line loss
reimbursement based upon the facts presented in this Cause.

OKLAHOMA AND CENTRAL AND SOUTH )
WEST CORPORATION REGARDING     )
PROPOSED MERGER                )



                                   STIPULATION


         The parties to this Stipulation, dated as of April 16, 1999, are the
Public Utility Division (Staff) and the Consumer Services Division (CSD) of the
Oklahoma Corporation Commission (OCC or Commission); American Electric Power
Company, Inc. (AEP); Central and South West Corporation (CSW); Public Service
Company of Oklahoma or any successor (PSO); and, the Attorney General of the
State of Oklahoma (Attorney General). The foregoing parties to this cause shall
be referred to individually either as a Signatory or by the acronym assigned
above, and collectively as the Signatories. The Signatories submit this
Stipulation to the Commission as representing a just and reasonable disposition
of the issues addressed in this Stipulation; the Signatories request approval of
this Stipulation and entry of an order consistent with this Stipulation.

         The Signatories stipulate and agree as follows:

                        STATEMENT OF SIGNATORIES' INTENT

         The purpose of the plan is to distribute net merger savings through a
credit rider to retail ratepayers. The minimum life of the credit rider is five
years. It is the intention of the Signatories to this Stipulation that, at a
minimum, a five-year plan be implemented. The costs to achieve the merger
incurred prior to the end of the first two years after the effective date of the
merger will be deferred and amortized. These costs are to be amortized during
the five-year period after the
<PAGE>   82
effective date of the merger. If a general rate change proceeding changes PSO's
base rates within the first five years after the effective date of the merger,
the shareholder savings imputation shall be used and the credit rider will
continue regardless of any changes to base rates. If a general rate change
proceeding changes PSO's base rates after the first five years after the
effective date of the merger, no shareholder savings imputations or deferred
costs to achieve amortization shall be used and the credit rider shall terminate
upon the implementation of new base rates. The Applicants commit to hold PSO
Oklahoma retail customers harmless from adverse impacts of the merger. PSO
commits not to seek a general base rate change prior to January 1, 2003. If PSO
seeks a general rate change from January 1, 2003 through the fifth year
anniversary of the effective date of the merger, the Applicants agree to a
$5,000,000 reduction to PSO's revenue requirement as otherwise determined by the
Commission. The parties acknowledge that there may be changes in the number of
Central and South West Services, Inc. (CSWS) or PSO employees located within
Oklahoma as a result of this merger and the level of such changes have not been
finally determined. The economic impacts of this merger are not addressed in
this partial Stipulation and remain unresolved. It is the intent of the
Signatories that all five attachments to this Stipulation be incorporated as if
set forth fully herein.

         SECTION 1. NON-OPPOSITION TO MERGER.

         Both the Staff and the Attorney General acknowledge that they will not
oppose the merger as to the issues stipulated herein before the Federal Energy
Regulatory Commission (FERC). Further, the Staff recommends that the Commission
file a position statement in consolidated FERC Docket Nos. EC98-40-000;
ER98-2770-000; and ER98-2786-000 indicating that it does not oppose the merger.
The Staff reserves the right to litigate before FERC the impact of the merger
upon the transmission system in Oklahoma, which includes the impact of the
merger upon other



                                       2
<PAGE>   83
Oklahoma jurisdictional utilities and also includes the impact of potential line
losses and potential increased congestion within Oklahoma.

         SECTION 2. THE PROPOSED PLAN.

         This Stipulation has been developed to ensure that Oklahoma retail
customers of PSO receive the benefits of the merger. The proposed plan set forth
below is reasonable and in the public interest.

         SECTION 3. SHARING OF NET NON-FUEL AND NON-PURCHASED POWER OPERATION
         AND MAINTENANCE EXPENSE SAVINGS.

         (a) PSO will implement a net merger savings (net of costs to achieve
the merger as defined in Section 3(b)) rider in Oklahoma that will reduce rates
to customers by the annual amount shown in Attachment 1 beginning with the first
revenue month after the effective date of the merger. Each individual year's
rate reduction will apply for a twelve month period as presented in Attachment
1, with a $9,409,000 annual reduction to be applied in each of the years
following the end of the fifth year until new base rates for PSO become
effective pursuant to a general rate change proceeding.(1) At the end of the
five-year period, deferred costs to achieve amortization and shareholder savings
imputations as addressed in Section 3(c) shall terminate.

         (b) Costs to achieve the merger ("costs to achieve") are those costs
reasonably and prudently incurred within the first two years after the effective
date of the close of the merger in order to consummate the merger and combine
the operations of AEP and CSW. These costs include, but are not limited to,

- ----------
(1) The Signatories' understanding for the purpose of this Stipulation of what
constitutes a general rate change proceeding is one in which the overall
non-fuel base revenue requirements of the company are revised.

                                       3

telecommunication costs; and facilities consolidation costs. The costs to
achieve are to be recovered through merger savings. For Oklahoma retail
jurisdictional ratemaking purposes, PSO will defer the lesser of estimated or
actual costs to achieve incurred prior to the end of two years after the
effective date of the merger. These deferred costs will be amortized over a
five-year period beginning with the effective date of the merger. The amortized
costs for each year shall be proportionate to the aggregate estimated merger
savings for the corresponding year as seen in Attachment 1.

         Applicants shall credit the customer via an allocation methodology that
allocates the net merger savings according to Attachment 2.

         (c) If changes in base rates of PSO, pursuant to a general rate change
proceeding, occur within the first five years after the effective date of the
merger, the following rate treatments shall be reflected:

         (1)      Estimated non-fuel operation and maintenance expense merger
                  savings net of costs-to-achieve will be included in cost of
                  service as an allowable expense. The amount to be included in
                  the cost of service shall be based upon the test year period.

         (2)      Amortization of costs to achieve will be included in cost of
                  service as an allowable expense. The amount to be included in
                  the cost of service shall be based upon the test year. The
                  unamortized balance of costs to achieve will not be included
                  in rate base and no return will be allowed on the unamortized
                  balance of costs to achieve.

         (3)      The merger savings rate reduction rider as described in
                  Paragraph (a) above shall continue.

         (4)      The Applicants shall have the burden of proof to show that
                  they have substantially achieved the estimated level of merger
                  savings as shown in Attachment 1. If the Applicants cannot
                  demonstrate in any general rate change proceeding initiated
                  within the first five years after the effective date of the
                  merger, that they have substantially achieved the estimated
                  merger savings, then the shareholders' portion of net merger
                  savings (as shown in Attachment 1) shall not be included as a
                  cost of service expense.

         (5)      Attachment 3 is an example of the retail base rate treatment
                  described in this subsection.


                                       4
<PAGE>   85
         (d) For each year following the end of the fifth year after the
effective date of the merger, a $9,409,000 annual reduction will be reflected in
the net merger savings rate reduction rider. In any retail base rate change
proceeding after the fifth year after the effective date of the merger, the
following rate treatments will be reflected:

         (1)      No estimated non-fuel operation and maintenance expense merger
                  savings will be included in cost of service as an allowable
                  expense.

         (2)      No amortization of costs to achieve will be included as an
                  allowable expense.

         (3)      The merger savings rate reduction rider will cease upon the
                  effective date of the new base rates.

         (e) In the event the electric utility industry in Oklahoma is
restructured prior to the end of the fifth year after the effective date of the
merger, the then effective rider benefits, as described above in Section 3, and
costs to achieve amortization pursuant to Section 3(b) shall be deemed
applicable in their entirety to the rates of the unbundled services that remain
regulated by the Commission. The costs to achieve amortization and rider
benefits shall continue in full, and remain unaltered, for the five-year term,
except in the case of a general rate change proceeding initiated by a party
other than PSO.

         (f) In the event of any general rate change proceeding initiated by a
party other than PSO subsequent to industry restructuring and prior to the end
of the fifth year, the rider benefits, cost amortization, and shareholder net
savings imputation shall be reduced proportionate to the rates of regulated
unbundled services. It is the intent of the Signatories that the cost
amortization, net merger savings rider, and shareholder savings amputations
continue for the five-year term for those services subject to continued
regulation by the State of Oklahoma. It is also the intent of the Signatories
that the benefits would continue for the period of time in which the net merger
savings rider set forth in Section 3 above remains in effect for those services
subject to continued regulation by the State of Oklahoma.


                                       5
<PAGE>   86
         SECTION 4. SHARING OF FUEL AND PURCHASED POWER EXPENSE SAVINGS.

         After the effective date of the merger, all jurisdictional fuel and
purchased power expense savings resulting from the merger shall accrue to the
benefit of the retail customers through the existing fuel cost recovery
mechanism.

         SECTION 5. ACCESS TO BOOKS AND RECORDS.

         The Applicants agree that subject to regulatory authority, the OCC and
Attorney General will either have access in Oklahoma to copies of books and
records of AEP and its affiliates and subsidiaries (including their
participation in joint ventures) with respect to matters and activities that
relate to Oklahoma retail rates or AEP will pay reasonable and prudently
incurred travel expenses to conduct on-site review of books and records. The OCC
and Attorney General will have access to the books and records of PSO to the
degree required to fully audit, examine, or otherwise investigate transactions
between PSO and AEP affiliates.

         SECTION 6. AGREEMENT REGARDING STRANDED INVESTMENT.

         The Applicants commit and agree that stranded costs, if any, that PSO
may seek to recover will be on a stand-alone basis, and will be limited to the
ownership-interest of PSO's assets and obligations. PSO does not have any
stranded costs under current Oklahoma regulation. The merger by itself does not
create stranded costs.

         SECTION 7. MITIGATION.

         To mitigate any perceived impacts of the merger on the Applicants'
market power, the Applicants have proposed in their FERC merger application a
mitigation plan which includes the following:

         (1)      Divestiture of 300 megawatts of coal-fired generating capacity
                  at the Northeastern generating plant after such plant is no
                  longer required to meet PSO's native load demand requirements
                  subsequent to industry restructuring in Oklahoma.



                                       6
<PAGE>   87
         (2)      Sale of 300 megawatts per hour of energy on an interim basis
                  prior to the divestiture of the Northeastern capacity.

         (3)      Waiver of PSO's priority to the use of CSW interfaces with
                  other transmission systems to import centrally dispatched
                  energy from the existing AEP system in excess of 250
                  megawatts.

         (4)      Waiver of PSO's priority to the use of CSW interfaces to
                  import non-firm energy from non-affiliates.

         (5)      Schedule CSW's use of the two high voltage direct current
                  (HVDC) ties between ERCOT and the SPP on a first-in-time basis
                  for certain transactions.

         The Applicants commit to hold PSO Oklahoma retail customers harmless
from adverse impacts from these transactions. Attachment 4 to this agreement
describes the methodology that the Applicants will follow in order to hold PSO
Oklahoma retail customers harmless from adverse effects of the interim
mitigation sale.

         The Applicants' market power mitigation plan is reasonable and is
subject to approval at the FERC. To the extent that the market power mitigation
plan is modified by a final order of the FERC, the Applicants will inform the
Commission and the Attorney General of such modifications. The Applicants shall
make a filing with the Commission to address such modification, so as to ensure
that Oklahoma PSO retail customers are held harmless from adverse effects of
such plan, and quantify and determine the regulatory treatment of gains, if any.

         SECTION 8. BASE RATE MORATORIUM.

         Applicants will commit not to seek a base rate increase over base rates
as of the date of this Stipulation, subject to major Force Majeure provisions
set forth below, which would become effective prior to January 1, 2003. If a
rate review is sought by the Applicants after January 1, 2003 through the end of
the fifth year after the effective date of the merger, the Applicants shall make
a $5,000,000 reduction to the revenue requirement otherwise determined by the
Commission to be reasonable.



                                       7
<PAGE>   88
         SECTION 9. FORCE MAJEURE.

         Prior to January 1, 2003, if Force Majeure or events beyond the
influence and/or control of PSO occur, including Oklahoma legislative action
regarding industry restructuring or unbundling, PSO shall be entitled to file
for a general rate review pursuant to OAC 165:70 and in such case, PSO will have
the burden of proving (1) that its request for relief is a good faith request,
(2) that the event or occurrence was not directly or indirectly caused by PSO,
(3) the event or occurrence has at least an annual impact of $6,000,000 and (4)
that PSO had no direct or indirect control over the event or occurrence. The
Signatories will have the right to challenge PSO's request for rate relief. In
any rate proceeding pursuant to this Section, merger costs and savings will be
treated in accordance with Section 3.

         SECTION 10. REGULATORY AUTHORITY.

         Applicants agree not to assert in proceedings before this Commission,
or in court proceedings related to this Commission, that the authority of the
Securities and Exchange Commission ("SEC") as interpreted in Ohio Power v. FERC,
554 F.2d 779 (D.C. Cir. 1992.) cert. denied, 498 U.S. 73 (1992) impairs the
Oklahoma Corporation Commission's ability to examine the reasonableness of
non-power affiliate costs to be passed to PSO's retail customers. The parties
agree that the Ohio Power waiver does not include waiver of any arguments that
AEP/CSW may have with respect to the reasonableness of SEC approved cost
allocations, as opposed to the reasonableness of the costs themselves.

         SECTION 11. CAPITAL COSTS.

         The Applicants commit and agree that the cost of capital as reflected
in PSO's rates shall not be adversely affected by the result of AEP's
acquisition of CSW. The Applicants al so agree that subsequent to the completion
of the merger, the cost of capital from PSO should be set commensurate with the
risk of PSO and should not be affected by the merger. Applicants agree


                                       8
<PAGE>   89
that they will not oppose, in either a regulatory proceeding or an appeal of a
decision by the OCC, the application of the principal that the determination of
the cost of capital can be based on the risk attendant to the regulated
operations of PSO.

         SECTION 12. QUALITY OF SERVICE.

         The Applicants agree to the quality of service standards set forth in
Attachment 5.

         SECTION 13. MOST FAVORED NATIONS.

         The Applicants commit and agree that upon issuance of any final and
non-appealable order from the FERC, SEC, or any state or federal commission
addressing the merger, through stipulation or otherwise, providing any benefits
to customers of any jurisdiction or imposing any conditions on Applicants that
would benefit the customers of any jurisdiction, such net benefits and
conditions will be extended to PSO Oklahoma retail customers to the extent
necessary to achieve equivalent net benefits and conditions to the Oklahoma PSO
retail customers, provided the proposed merger is ultimately consummated. Joint
Applicants will provide to the director of the Public Utility Division and the
Attorney General any final and non-appealable order from the FERC, SEC, or any
state or federal commission addressing the merger, through stipulation or
otherwise.

         SECTION 14. MERGER SAVINGS HOLD HARMLESS CONDITIONS.

         The Applicants agree to hold harmless the retail customers of PSO from
unforeseen events that materially diminish the estimated benefits of the merger
and from major deviations from the Applicants' stated representations of
estimated merger benefits as reflected in Column 5 of Attachment 1 in
calculating the benefits to flow to retail customers.

         SECTION 15. COST RECOVERY.

         If the merger is not consummated, the Applicants commit and agree not
to seek to recover transition or transaction costs, or termination fees,
including but not limited to the "Out of Pocket"



                                       9
<PAGE>   90
and "Topping Out" fees associated with the merger described in Sections 9.5 and
9.6 of the Agreement and Plan of Merger By and Among American Electric Power
Company, Inc., Augusta Acquisition Corporation and Central and South West
Corporation dated December 21, 1997 (Merger Agreement) and further commit and
agree not to seek to recover fees related to the merger that may be charged by
Morgan Stanley.

         SECTION 16. NON-RECOURSE PROVISION.

         A PSO affiliate may not incur debt or pledge the stock of PSO in a
manner that, on the affiliate's default, would permit a creditor to have
recourse against the regulated assets of PSO.

         SECTION 17. REGIONAL TRANSMISSION ORGANIZATION.

         The Applicants offer the following as a condition to approval of the
merger:
         Prior to the later of six months prior to retail customer choice, or
December 31, 2001, the Applicants agree that AEP will file with the FERC an
unconditional application to, consistent with the RTO agreement, transfer the
operational control of bulk transmission facilities owned, controlled and/or
operated by AEP currently located in the Southwest Power Pool to a FERC-approved
Regional Transmission Organization directly interconnected with the AEP
transmission facilities. The above date shall be extended, if necessary, to 75
days after FERC issues the order on an RTO to which AEP is a signatory that is
filed before June 30, 2001. Notwithstanding any other provision of this
agreement, the Joint Applicants will not be precluded from seeking recovery of
costs required to implement a Regional Transmission Organization.

         SECTION 18. NOTICE OF CLOSING.

         AEP shall notify the parties of the date the merger closes promptly
after the closing occurs. This notice shall be sent to the parties in care of
their respective attorneys of record at the addresses shown on the service list
in this docket.


                                       10
<PAGE>   91
         SECTION 19. SUPPORT OF STIPULATION AND EFFECT OF MODIFICATION OF
         STIPULATION.

         The Signatories shall recommend that the Commission enter an order
consistent with this stipulation in all material respects. If the Commission
enters an order inconsistent with this stipulation, any Signatory may withdraw
its consent to this Stipulation, and the withdrawing Signatory's agreement to
this Stipulation shall be extinguished. The withdrawing Signatory shall not be
deemed to have in any way waived or compromised any right to urge that a
different result, methodology, or position be required by law or the facts.

         The Signatories agree that the provisions of this Stipulation are the
result of extensive negotiations and that the terms and conditions of this
Stipulation are interdependent. The Signatories agree that settling the issues
in this Stipulation is in the public interest, and, for this reason, they have
entered into this Stipulation to resolve among themselves the issues in this
Stipulation. This Stipulation is a compromise and settlement among the
Signatories, and no Signatory is bound beyond its obligation to support this
Stipulation. This Stipulation shall not constitute nor be cited as precedent or
deemed an admission by any Signatory in any other proceeding except as necessary
to enforce its terms before the Commission or any state court of competent
jurisdiction. The Commission's decision, if it enters an order consistent with
this Stipulation, will be binding as to the matters decided regarding the issues
described in this Stipulation, but the decision will not be binding with respect
to similar merger plans that might arise in other proceedings. A Signatory's
support of this Stipulation may differ from its position or testimony in other
causes. To the extent there is a difference, the Signatories are not waiving
their positions in other causes. Because this is a stipulated agreement, the
Signatories are under no obligation to take the same positions as set out in
this Stipulation in other dockets.

                    MITIGATION SALE HOLD HARMLESS METHODOLOGY

The following describes the methodology proposed by the Applicants to account
for the margins from the Market Mitigation Sale in order to meet the Hold
Harmless provisions of the agreements between the Applicants and the Arkansas,
Louisiana and Oklahoma commissions.

Applicants will do an "after the fact" calculation, using actual hourly data, to
reconstruct the dispatch and determine margins from the mitigation sale. This
calculation will be referred to as the Regulatory Mitigation Reconstruction
(RMR). The RMR will not alter the methodology currently used by CSW under the
CSW Operating Agreement to account for transactions by and between the CSW
Operating Companies. The RMR will be used to determine if the mitigation sale
resulted in negative margins, which should not be included in the retail
customer eligible fuel and provide the mechanism by which the Applicants will
ensure that retail customers are held harmless from this sale. The RMR will
calculate the margins on a monthly basis, and any margins above credits to
eligible fuel will be calculated and deferred monthly and refunded annually such
that customers are protected from any negative margins on an annual basis.

The RMR will reconstruct the dispatch on a hourly basis using the installed
generation capacity owned by the CSW Operating Companies (both off-line and
on-line) plus the firm annual purchases included in CSW's CDR. The purchases
will be used as dispatchable resources at the price incurred in that hour. (Firm
annual purchases will be modeled as a reduction in load. Because the purchase
expense and the MW amount are held constant in both production cost cases, the
model ignores the purchase price for the firm annual purchases.) The generation
resources will be economically dispatched to serve the actual hourly load
included in the CSW Internal Economy dispatch level of the CSW Interchange Cost
Reconstruction (ICR). The program will determine the cost of production for the
level of dispatch referred as the Own Load Production Cost. The Mitigation Sale
(scheduled in that hour) will then be added to the load and the dispatch
performed again. The resulting production costs are referred to as the Total
Production Cost. The difference between Total Production Cost and the Own Load
Production Cost is the Mitigation Production Cost.

The energy revenues from the sale (S14/MWh) minus Mitigation Production Cost and
the costs of hedges to manage fuel cost risks and any expenses due to the buy
back provisions of the sale equals the Mitigation Margin. If the Mitigation
Margin is positive then the margin would be treated in the same manner as any
other off-system sales margin. The revenues received from the mitigation sale
auction are referred to as the Mitigation Reservation Margin. These margins will
be used to offset any negative Mitigation Margin calculated above. The
Mitigation Margins will be deferred on a monthly basis and all gains and losses
will be accumulated annually and flowed through 30 days after the end of a
calendar year. Alternatively, if the Mitigation Margin is positive, the
Mitigation Reservation Margin will be treated in the same manner as any other
off-system sales margin. When the Mitigation Margin is negative for the month,
then the Mitigation

                    MITIGATION SALE HOLD HARMLESS METHODOLOGY

Reservation Margin (calculated on an monthly basis) will be credited in an
amount necessary to make the Mitigation Margin zero. If the Mitigation Margin is
still negative, after giving full credit for the Mitigation Reservation Margin,
this amount determines the monthly Hold Harmless credit applied to eligible
fuel. The positive or negative monthly Mitigation Margin will be accrued
monthly, and the Hold Harmless credits in a month may be reversed if Mitigation
Reservation Margin is available in a succeeding month.

The expenses and revenues associated with the Mitigation Margin will be
allocated to the CSW Operating Companies based on the relative participation of
their units in the sale as determined in RMR.

The following is the RMR algorithm:

OWN LOAD - the sum of the CSW Operating Companies native load plus firm purchase
and sale obligations.

OWN LOAD PRODUCTION COST (OLPC) - The cost of production to serve CSW Own Load
requirement plus daily regulating and operating reserves. This is the Internal
Economy dispatch level of ICR.

TOTAL PRODUCTION COST (TPC) - The cost of production to serve CSW Own Load
requirements plus daily regulating and operating reserves plus the Mitigation
Sale.

MITIGATION ENERGY SALES REVENUE (MESR) - The revenue associated with the
Mitigation Energy, at $14/MWh.

MITIGATION PRODUCTION COST (MPC) - the cost or producing the energy to supply
the Mitigation Sale.

MITIGATION MARGIN (MM) - Margin resulting from the mitigation sale.

MITIGATION RESERVATION MARGIN (MRM) - The annual revenue from the reservation
fees determined in the mitigation auction. The annual revenue is divided by 12
to determine a monthly MRM.

ENERGY RECALL EXPENSE (ERE) - The payments made to the Mitigation Sale
purchasers when CSW recalls the energy in order to serve firm native load. These
payments will be calculated on an hourly basis.

MPC = TPC - OLPC
MM = MESR - MPC - ERE

                      PROPOSED QUALITY OF SERVICE STANDARDS
  AMERICAN ELECTRIC POWER COMPANY, INC., AND CENTRAL AND SOUTH WEST CORPORATION



Standards related to the Company's customer service center calls:

- -    On an annual basis, the customer call center's average answer time for
     customer calls shall not exceed fifty-five seconds.

- -    As used in this paragraph, "answer" means the operator, service
     representative, or automated system is ready to render assistance and/or
     accept the information necessary to process the call.

- -    Answer time shall be measured from the first ring at the call enter or at
     the point the customer begins to wait in queue, whichever comes first.

- -    If AEP/CSW utilizes a menu driven, automated, interactive answering, the
     initial recorded message presented by the system to the customer shall only
     identify the Company and the general options available to the customer,
     including the option of being transferred to a live attendant. At any time
     during the call, the customer shall be transferred to a live attendant if
     the customer fails to interact with the system for a period of ten seconds
     following any prompt.

- -    Customers shall not be delayed from reaching the queue by any promotional
     or merchandising material not selected by the customer.

- -    Performance data during a "major event" or comparable term as such is used
     by the electric distribution company in its emergency plan, and subject to
     review and acceptance by the Commission shall be excluded from the
     calculation of monthly minimum service values pursuant to the paragraphs
     above. If the Company and the Commission cannot agree on the definition of
     a "major event" or comparable term, Staff and /or the Company may apply,
     within forty-five days after the submission of the Company's proposal, to
     the Commission for a hearing, file a written report and/or recommendations.

Standards related to the Company's response to requests for service:

- -    Ninety-five percent (95%) of the Company's application for new electric
     service, not involving a line extension or new facilities, shall be filled
     by the end of the next business day after the customer's location is ready
     for service and the customer submits a service request, excluding those
     orders where a later date was specifically requested by the customer.

- -    The Company will notify customers two days before non-emergency, temporary
     service interruptions required to improve or maintain performance of the
     Company's system, and shall meet its commitment in ninety-five percent
     (95%) of such instances.

- -    The Company shall comply with the deadlines established for meter testing,
     written reports on meter testing, and reconnection of service, in OAC
     165:35 and any amendments thereto.

<PAGE>   102
Standard related to the Company's Billing Adjustments:

- -    The Company shall maintain its infrastructure and customer service in such
     a manner that the average monthly rate of actual customer over-billing
     errors per 1,000 customers does not exceed ten. Estimated billings due to
     inclement weather, lack of access to customer premises, damaged metering
     equipment, and errors due to erroneous information provided from customers
     shall be excluded from this measurement.

All of the above standards and measurements are on a PSO Company-wide, 12-month
basis. The customer service standards established under this agreement shall
remain in effect for a period of no more than three years following the
effective date of the merger. In the event the OCC changes any of its rules
concerning customer service standards, such changes shall automatically be
incorporated in this agreement. Additionally, these standards can be changed
during the three-year period to reflect any performance-based ratemaking plans
or rules for PSO and/or the electric industry.

Standard related to Customer Satisfaction:

- -    PSO shall provide a Customer Satisfaction Index Report to the OCC on an
     annual basis. This report will provide at a minimum data on: a.) the
     fairness and reasonableness of rates; b.) reliability/high quality service;
     c.) courteous and understanding employees; and, d.) quick service
     restoration after an outage. In addition, if a decline in the trend in the
     categories noted above is reported, PSO shall provide information to the
     OCC as to the actions being taken in order to correct such decline(s). The
     data to be provided in conjunction with this paragraph shall be provided
     (and maintained by the OCC) on a confidential basis.

Standards related to Company's Reliability Performance:

The merged company, AEP and CSW, commits to maintain its reliability performance
for its Oklahoma retail customers as determined by the System Average
Interruption Frequency Index (SAIFI) and the System Average Interruption
Duration Index (SAIDI) within the range experienced during the period 1997
through 1999 (inclusive), absent a major outage event beyond the scope of any
the PSO system experienced during the same period. The SAIFI and SAIDI indices
are defined as shown below.

PSO will provide information/substantiation of its performance for each of these
measures on an annual basis by the end of May of the year following the year in
question.

                                   INTEGRATED
                            STIPULATION AND AGREEMENT


                  This Integrated Stipulation and Agreement ("Agreement") is
made and entered into by and among American Electric Power Company, Inc. ("AEP")
and Central and South West corporation ("CSW"), referred to jointly as
"Applicants," and other entities whose authorized representatives have signed
it. Applicants and such other signatories are at times referred to jointly
herein as the "Signatories" (also referred to individually as "Signatory").

                  WHEREAS, on April 30, 1998, AEP and CSW filed an Application
with the Public Utility Commission of Texas ("PUCT") pursuant to Section 14.101
of the Public Utility Regulatory Act ("PURA"), requesting that the PUCT find
their proposal to combine their systems ("merger") to be consistent with the
public interest ("Application");

                  WHEREAS, notice of the filing of the Application and the
Commission's proceeding to evaluate it was published once each week for four
consecutive weeks in newspapers of general circulation in each Texas county
served by Central Power and Light Company ("CPL"), West Texas Utilities Company
("WTU") and Southwestern Electric Power Company ("SWEPCO"), the electric utility
operating company subsidiaries owned by CSW. In addition, individual notice was
given by mail to each Texas customer of CPL, WTU and SWEPCO and supplemental
notice was given in accordance with Order Nos. 43 and 45;

                  WHEREAS, the Signatories desire to resolve all outstanding
merger-related issues among them;

                  WHEREAS, this Agreement involves all issues in this proceeding
in a manner the Signatories believe is consistent with the public interest, and
the Signatories, along with the non-signatory parties who do not oppose the
Agreement, represent diverse interests;

                  WHEREAS, the Signatories believe that fully contested hearings
in this case would be time-consuming and expensive for all parties and that the
public interest will be served by adoption of an order consistent with this
Stipulation;

                  WHEREAS, the WTU rate freeze expired in October 1998;

                  WHEREAS, there are currently pending in the Texas courts
appeals of prior PUCT Docket Nos. 14965 and 17460 concerning CPL and SWEPCO,
respectively;

                  WHEREAS, the Signatories desire to resolve all issues in
Docket No. 17460 and certain issues in Docket No. 14965 as part of this
Agreement;

                  WHEREAS, the PUCT is currently considering adoption of an
affiliate code of conduct and has recently considered reliability and service
quality issues in several proceeding;
<PAGE>   7
                  WHEREAS, the Signatories desire to address affiliate code of
conduct and service quality issues in response to the PUCT's stated concerns;

                  WHEREAS, AEP and CSW previously entered into a Stipulation and
Agreement with the Office of Public Utility Counsel and certain Cities served by
CSW;

                  WHEREAS, the parties to the previous Stipulation and Agreement
have now reached agreement with additional parties, including the General
Counsel of the Public Utility Commission of Texas, Texas Industrial Energy
Consumers, the State of Texas, and the Low-Income Intervenors;

                  WHEREAS, this subsequent agreement accomplishes the
Signatories' desire to resolve as many pending and potential issues and disputes
existing among them as possible; and

                  WHEREAS, the Signatories wish to consolidate the terms of this
subsequent agreement with the terms of the previous Stipulation and Agreement to
produce this Integrated Stipulation and Agreement.

                  NOW, THEREFORE, in consideration of the mutual agreements and
covenants herein, the Signatories, through their undersigned representatives,
agree to and recommend for PUCT approval the following provisions of this
Agreement as a means of fully resolving the issues among them in Docket No.
19265 and other proceedings referenced in this Agreement:

<PAGE>   8
2.   Support For the Merger

         A.       The signatories hereby stipulate and agree, and urge the PUCT
                  to issue a Final Order finding, that the Application in Docket
                  No. 19265, as modified and contained in this Agreement, is in
                  the public interest and otherwise consistent with the
                  requirements of Section 14.101 of PURA.

         B.       All Signatories agree to fully support this Agreement in all
                  respects and to use all reasonable efforts to obtain prompt
                  adoption of a final order in Docket No. 19265 based upon this
                  Agreement. Further, all Signatories agree to defend the terms
                  of this Agreement.

3.   Regulatory Plan

         A.       Texas Retail Rate Reductions.

                  The Texas operating companies will implement net merger
                  savings rate reduction riders which will reduce rates to
                  customers by the annual amounts shown in Attachment A
                  beginning with the first revenue month after the effective
                  date of the merger. The annual rate reduction amounts shown in
                  Attachment A will be allocated to rate classes based 50% upon
                  a total revenues factor and 50% upon a year-end customer
                  factor, as shown on Attachment A. Table A-1. Each individual
                  year's rate reduction will apply for a twelve month period
                  with the last reduction continuing to apply in years following
                  the end of year six until base rates for the Texas operating
                  company are changed. Notwithstanding any base rate proceeding
                  during the six year period after the effective date of the
                  merger, the annual amounts shown in Attachment A will remain
                  in effect.

         B.       The annual base rate reduction amounts are net "bottom-line"
                  amounts not subject to any offset.

         C.       The Texas operating companies agree to implement the above
                  rate reductions in the manner and amounts described above
                  notwithstanding any changes to the current regulatory
                  structure in Texas or implementation of a
                  legislatively-mandated rate freeze. In the event that retail
                  electric restructuring legislation is implemented in Texas
                  including any divestiture, unbundling or restructuring, the
                  Texas operating companies agree to apply the regulatory plan's
                  provisions to regulated rates of their customers.

         D.       The Signatories agree that any legislatively mandated
                  reductions or credits to base rates that are part of any
                  retail electric restructuring legislation implemented in Texas
                  shall not diminish or offset, but shall be in addition to, the
                  base rate reductions established in this proceeding.

         E.       The Merged Company and Texas operating companies agree not to
                  request under currently existing law any new resource
                  surcharge or Power Cost Recovery Factor

                                       3
<PAGE>   9
                  ("PCRF") for increase in any existing resource surcharge or
                  PCRF that would become effective within a period of six years
                  after the effective date of the merger or until retail
                  electric restructuring legislation is implemented in Texas,
                  whichever first occurs. Notwithstanding the previous sentence,
                  the Merged Company or a Texas operating company may request a
                  new or increased surcharge or PCRF if the requested surcharge
                  or PCRF was authorized in Docket Nos. 18041 or 18845 or is to
                  provide for recovery of fuel and purchased power energy
                  savings resulting from demand-side management ("DSM") as
                  required by the preliminary integrated source plan in Docket
                  No. 16995.

                  In addition, the Merged Company or a Texas operating company
                  may request a surcharge or PCRF related to acquisition of
                  additional short-term capacity or DSM resources required to
                  meet the load requirements specified in subparagraphs (1) and
                  (2) below. The following provisions will apply to any such
                  request made by the Texas operating companies:

                  (1)      for amounts of short-term capacity or DSM resources
                           required to meet a reserve margin based upon actual
                           native loan requirements plus a 15% reserve margin
                           during each annual period, the Merged Company and
                           Texas operating companies agree that the costs which
                           may be requested in a surcharge or PCRF will be
                           limited to the cost of the short-term capacity or DSM
                           less the amount of production capacity costs per
                           kilowatt embedded in current base rates times the
                           kilowatts of short-term capacity of DSM required to
                           meet the actual native load requirements and 15%
                           reserve margin.

                  (2)      For amounts of short-term capacity or DSM resources
                           required by the PUCT to be purchased in excess of
                           actual native load requirements plus a 15% reserve
                           margin during each annual period, the Merged Company
                           and Texas operating companies agree that the costs
                           which may be requested in a surcharge or PCRF will be
                           limited to the cost of the short-term capacity or
                           DSM.

                  Any PCRF implemented pursuant to this section is not subject
                  to adjustment pursuant to Section 3.F.(3) below. The Merged
                  Company's request for recovery of any surcharge or purchased
                  power costs pursuant to this Section 3.E. will not be
                  considered a base rate case and will not trigger any rate
                  treatments illustrated on Attachment F, and the Attachments A
                  and H rate credits will remain in place. This Agreement does
                  not prevent any Signatory from opposing any request referenced
                  in this Section 3.E.

         F.       (1)      Subject to subparagraph F.(3), in a proceeding to
                           change base rates of a Texas operating company to
                           become effective prior to the end of the six year
                           period after the effective date of the merger, a "net
                           merger savings" expense item, the purpose of which is
                           to prevent ratepayers from receiving their share of
                           merger savings twice and to ensure that the
                           shareholders

                                       4
<PAGE>   10
                           retain their share of net merger savings attributable
                           to the Texas operating company, will be reflected as
                           reasonable and necessary operating expenses in the
                           calculation of cost of service. The annual amounts of
                           the net merger savings expense item for each of the
                           Texas operating companies are included in Attachment
                           B. The amount to be included in cost of service shall
                           be based upon the test year period.

                  (2)      The Merged Company and Texas operating companies will
                           defer and amortize their merger related
                           costs-to-achieve over a six year period following the
                           effective date of the merger. Costs to achieve the
                           merger are those costs incurred to consummate the
                           merger and combine the operations of AEP and CSW.
                           These costs include, but are not limited to,
                           investment banking fees; consulting and legal
                           services incurred in connection with obtaining
                           regulatory and shareholder approvals; transition
                           planning and development costs; employee separation
                           costs including severance costs, change-in-control
                           payments and retraining costs; and facilities
                           consolidation costs. Subject to subparagraph F. (3),
                           in any proceeding to change base rates of a Texas
                           operation company to become effective prior to the
                           end of the six year period after the effective date
                           of the merger and that is not initiated to implement
                           electric industry restructuring legislation, the
                           annual amount of amortization of costs to achieve the
                           merger included in Attachment C will be reflected as
                           a reasonable and necessary expense included in the
                           calculation of cost of service.

                  (3)      In any proceeding initiated by a Texas operation
                           company requesting an increase to overall base rate
                           revenues to become effective prior to end of the six
                           year period after the effective date of the merger:

                           (a)      The net merger savings expense item and
                                    annual amount of amortization of costs to
                                    achieve the merger will not be included in
                                    the calculation of the cost of service
                                    unless the Texas operating company
                                    demonstrates:

                                    (i)      that the proposed rate increase
                                             results from circumstances not
                                             directly or indirectly related to
                                             the merger; and

                                    (ii)     that the full level of achieved
                                             merger savings for the applicable
                                             year as reflected in Attachment D
                                             have been achieved; and

                           (b)      The revenue requirements otherwise
                                    determined to be reasonable and necessary
                                    will be reduced by the annual amounts
                                    included in Attachment E.

                  (4)      The Merged Company and the Texas operating companies,
                           subject to the following force majeure provisions,
                           agree not to initiate a base rate

                           proceeding seeking an overall base rate revenue
                           increase to be effective prior to January 1, 2003 or
                           three years from the effective date of the merger,
                           whichever is later (the "rate moratorium"):

                           (a)      Changes in statutory Federal income tax
                                    provisions which result in a material known
                                    and measurable increase of tax expense of
                                    the Texas operating company initiating the
                                    proceeding;

                           (b)      Legislative or governmental regulatory
                                    action, other than loss of load resulting
                                    from electric industry restructuring, which
                                    has a material direct impact on the Texas
                                    operating company's non-fuel cost of
                                    providing service;

                           (c)      Other material increases in a Texas
                                    operating company's known and measurable
                                    annual non-fuel operating expenses which are
                                    outside its control; and

                           (d)      A review of the Texas operating company's
                                    rates instituted and allowed to proceed
                                    under PURA Section 36.151.

                           For purposes of this force majeure provision, the
                           annual levels of materiality for each Texas operating
                           company on a Texas retail basis shall be 5% of
                           normalized base revenues for the previous year. For
                           example, for a force majeure event occurring in 2001,
                           the annual level of materiality would be 5% of the
                           normalized base revenues for the year 2000.

                  (5)      Subject to the limitations in Sections 3.B, 3.C and
                           3.D above, during the rate moratorium the Texas
                           operating companies may request and support any
                           changes to rates that they believe appropriate or
                           desirable in connection with any filings required to
                           implement any regulatory or legislatively-imposed
                           restructuring or unbundling of services provided by
                           electric companies.

                  (6)      The Texas operating companies may make filings during
                           the rate moratorium which either: (1) modify tariffs,
                           riders, or terms and conditions while not increasing
                           aggregate base revenues for major rate classes
                           (residential, commercial, industrial, municipal and
                           lighting) or (2) add tariffs, riders, or terms and
                           conditions to address competitive conditions or
                           secure additional load that will not shift allocable
                           costs under such tariffs, riders, or terms or
                           conditions to other major rate classes.

                  (7)      The rate moratorium does not preclude the
                           implementation of any surcharge or other rate
                           mechanism found appropriate as a result of a remand
                           to the PUCT from a court proceeding.

                  (8)      An illustration of the impact of this Agreement on
                           the revenue requirements of each Texas operating
                           company in the event a base rate

                           proceeding is initiated during the six-year period
                           after the effective date of the merger is included as
                           Attachment F. In the event of any request to change
                           rates under subparagraph (5), (6) or (7), above, the
                           annual rate credits shown in Attachments A and H will
                           remain in effect.

         G.       Off-System Sales Margins.

                  (1)      CPL off-system sales margins up to $1.75 million
                           shall be credited to customers. For any CPL
                           off-system sales margins between $1.75 million and
                           $2.62 million, 85% shall be credited to customers and
                           15% of such margins shall be retained by the
                           shareholders. For any CPL off-system sales margins
                           above $2.62 million, 50% of such margins shall be
                           credited to customers and 50% of such margins shall
                           be retained by the shareholders.

                  (2)      SWEPCO off-system sales margins up to $1.35 million
                           shall be credited to customers. For any SWEPCO
                           off-system sales margins between $1.35 million and
                           $2.03 million, 85% of such margins shall be credited
                           to customers and 15% of such margins shall be
                           retained by the shareholders. For any SWEPCO
                           off-system sales margins above $2.03 million, 50% of
                           such margins shall be credited to customers and 50%
                           of such margins shall be retained by the
                           shareholders.

                  (3)      WTU off-system sales margins up to $900,000 shall be
                           credited to customers. For any WTU off-system sales
                           margins between $900,000 and $1.35 million, 85% of
                           such margins shall be retained by the shareholders.
                           For any WTU off-system sales margins above $1.35
                           million, 50% of such margins shall be credited to
                           customers and 50% of such margins shall be retained
                           by the shareholders.

                  (4)      The provisions as to off-system sales margins shall
                           be in effect for a period of five years from the
                           effective date of the merger.

                  (5)      The dollar figures shall apply on a calendar-year
                           basis.

                  (6)      Off-system sales margins to be credited to customers
                           under this subsection shall be made in the form of
                           revenue credits in fuel reconciliation proceedings.

         H.       Fuel Savings.

                  All reconcilable fuel and purchased power savings shall be
                  passed through to customers in accordance with PUCT rules and
                  proceedings for fuel factor adjustments and fuel
                  reconciliation (consistent with the proposal of the
                  Applicants).

4.       Regulatory Jurisdiction

         A.       The Merged Company and the Texas operating companies commit
                  and agree that they will not contend in any forum that the
                  jurisdiction of the PUCT over any Texas operating company is
                  changed as a result of the merger.

         B.       The Merged Company commits to file any allocation of the cost
                  of the new generation of transmission facilities with the
                  Federal Energy Regulatory Commission ("FERC") and to notify
                  the PUCT of any such filings at the time they are made.

         C.       The Merged Company agrees not to assist in proceedings before
                  the PUCT or in appeals of PUCT orders that the authority of
                  the Securities and Exchange Commission ("SEC"), as interpreted
                  in Ohio Power Co. v. FERC, 954 F.2d 779 (D.C. Cir. 1992) cert.
                  denied, 498 U.S. 73 (1992) impairs the ability of the PUCT to
                  examine and determine the reasonableness and necessity of
                  non-power affiliate transaction costs of the Texas operating
                  companies. The Signatories agree that this agreement does not
                  include a waiver of any arguments that the Merged Company may
                  have with respect to the reasonableness of SEC approved costs
                  allocations, as opposed to the reasonableness of the costs
                  themselves.

         D.       The Merged Company will not seek recovery of AEP mine-closing
                  costs except to the extent that such closing costs are
                  reflected as a component of AEP fueled costs utilized for
                  economy energy sales under the Systems Integration Agreement.
                  Economy energy sales will only be made under the Systems
                  Integration Agreement when both the East and West zones will
                  achieve coast savings.

         E.       The Merged Company commits and agrees that any stranded costs
                  that CPL, SWEPCO or WTU may seek to recover will be on a
                  stand-alone basis, and will be limited to the
                  ownership-interest of CPL, SEPCO or WTU in its respective
                  assets and obligations. The Merged Company agrees not to seek
                  or recover any stranded costs associated with the existing AEP
                  system from Texas customers. The Signatories agree not to
                  propose the allocation of any stranded costs associated with
                  the CSW system to customers of the existing AEP operating
                  companies. STP will be used only to serve Texas customers.

         F.       The Merged Company will provide the PUCT with notice of
                  filings which propose new allocation factors with the SEC or
                  FERC. The notice will include a description of the proposed
                  factors.

         G.       The Merged Company agrees not to implement further connection
                  between the Electric Reliability Council of Texas ("ERCOT")
                  and the Southwest Power Pool ("SPP") or the Western Systems
                  Coordinating Council ("WSCC") without providing prior notice
                  to the PUCT and all members of ERCOT and without first
                  obtaining a Section 211 order from the FERC. Any such
                  interconnect proposed will comply with legal and current
                  contractual requirements for making such interconnections.

         H.       Subject to due process rights to a public hearing and
                  opportunity to present evidence in support of their position,
                  CPL and WTU agree not to terminate their membership in ERCOT
                  without the prior written approval of the PUCT. The Merged
                  Company will not include CPL and the ERCOT portion of WTU in
                  an Independent System Operator ("ISO") outside ERCOT without
                  the prior written approval of the PUCT, with CPL and WTU
                  afforded the right to seek this determination through the
                  PUCT's contested case hearing process. SWEPCO will not
                  withdraw from the SPP without first seeking approval from the
                  PUCT.

         I.       CPL and WTU will continue to file rates for transmission
                  services at the FERC in accordance with ERCOT regional pricing
                  and terms and conditions as established by the PUCT so long as
                  CPL and WTU are members of ERCOT or until such time as ERCOT
                  is no longer subject to the jurisdiction of the PUCT. CPL and
                  WTU will comply with all Texas transmission statutes and
                  rules, including Transmission Cost of Service ("TCOS")
                  allocations. CPL and WTU commit to make TCOS filings with the
                  PUCT in accordance with PUCT rules and procedures. The PUCT
                  will determine CPL's and WTU's transmission costs in
                  accordance with the PUCT's transmission rules. CPL and WTU
                  will submit and support the results of the PUCT orders
                  concerning TCOS for CPL and WTU in FERC transmission rate
                  filings for intra-ERCOT transmission service.

         J.       The Merged Company agrees that it should not double recover
                  Direct Current ("DC") tie costs and will make all necessary or
                  appropriate adjustments to prevent double recovery, including,
                  but not limited to, removal of any DC tie costs included in
                  CPL, WTU and TCOS.

         K.       The Merged Company will comply with any Texas legislation or
                  administrative order providing for direct retail access. This
                  requires complying with all conditions governing such
                  legislation and/or order, including conditions related to the
                  recovery and quantification of stranded costs, if any.
                  Notwithstanding the foregoing, the Merged Company does not
                  waive any rights which it may have to challenge the legality
                  of any legislation or administrative orders.

         L.       The Merged Company will abide by the ultimate resolution of
                  affiliate allocation issues in the Docket No. 14965 appeal,
                  i.e, whether the PUCT may determine that the Company applied
                  the wrong SEC factor to an affiliate expense.

5.       Affiliate Standards

         The Merged Company agrees to comply with affiliate rules adopted in
         either restructuring legislation or in PUCT rules. The Merged Company
         also agrees to comply with all existing statutes and PUCT rules
         pertaining to affiliate transactions. Until a statute or rule governing
         affiliate transactions is adopted, the Merged Company agrees to comply
         with the affiliate standards set forth below. The following affiliate
         standards shall apply from the effective date of merger until the new
         affiliate standards imposed by state legislation or PUCT rule become
         effective.

                                       9

         A.       The terms "exempt wholesale generator" and "power marketer"
                  are defined in PURA Section 31.002.

         B.       The financial policies and guidelines for transactions between
                  an AEP operating company and its affiliates shall reflect the
                  following principles:

                  (1)      An AEP operating company's retail customers shall not
                           subsidize the activities of the operating company's
                           non-utility affiliates or its utility affiliates.

                  (2)      An AEP operating company's costs for jurisdiction
                           rate purposes shall reflect only those costs
                           attributable to its jurisdiction customers.

                  (3)      The principals set forth in subparagraphs (1) and
                           (2), above, shall be applied to prevent costs found
                           to be just and reasonable for ratemaking purposes by
                           the affected state commission being left unallocated
                           or stranded between various regulatory jurisdictions,
                           resulting in the failure of the opportunity of timely
                           recovery of such costs by the operating company
                           and/or its utility affiliates; provided, however,
                           that no more than one hundred percent of such costs
                           shall be allocated on an aggregate basis to the
                           various regulatory jurisdictions.

                  (4)      An AEP operating company shall maintain and utilize
                           accounting systems and records which are sufficient
                           to identify and appropriately allocate costs between
                           the operating company and its affiliates, consistent
                           with these cross-subsidization principles and the
                           financial policies and guidelines set out in this
                           subparagraph B.

         C.       The PUCT and other municipal regulatory authorities under PURA
                  shall have access to the books and records of any affiliate of
                  a Texas operating company to the same extent and in like
                  manner that the PUCT has over a public utility operating
                  company if the affiliate has had direct or indirect
                  transactions with the Texas operating company. The access
                  shall be sufficient to enable the PUCT or other regulatory
                  authority to conduct a complete analysis and make appropriate
                  determinations under PURA Section 36.058. Upon request of the
                  PUCT, such employees, officers, books and records will be made
                  available in Austin, Texas to the PUCT. Each AEP operating
                  company shall maintain, in accordance with generally accepted
                  accounting principles, books, records, and accounts that are
                  separate from the books, records, and accounts of its
                  affiliates consistent with Part 101 - Uniform System of
                  Accounts Prescribed for Public Utilities and Licensees Subject
                  to the Provisions of the Federal Power Act. Any objections to
                  providing all books and records must be raised before the PUCT
                  and the burden of showing that the request is unreasonable or
                  unrelated to the proceeding is on the AEP operating company.
                  The confidentiality of competitively sensitive information
                  shall be maintained in accordance with the rules and
                  regulations of the PUCT and the Texas Public Information Act.

         D.       In accordance with generally accepted accounting principles
                  and consistent with state and federal guidelines, an AEP
                  operating company shall record all transactions with its
                  affiliates, whether direct or indirect. An AEP operating
                  company and its affiliates shall maintain sufficient records
                  to allow for an audit of the transactions involving the
                  operating company and its affiliates. Asset transfers from an
                  AEP operating company to a non-utility affiliate and asset
                  transfers from a non-utility affiliate to an AEP operating
                  company shall be at fully distributed costs for book purposes
                  in accord with current SEC requirements or other statutory
                  requirements of the SEC have no jurisdiction.

         E.       An AEP operating company shall not allow a non-utility
                  affiliate to obtain credit under any arrangement that would
                  permit a creditor, upon default, to have recourse to the
                  operating company's assets. The financial arrangements of an
                  AEP operating company's affiliates are subject to the
                  following restrictions:

                  (1)      Any indebtedness incurred by a non-utility affiliate
                           will be without recourse to the operating company.

                  (2)      An AEP operating company shall not enter into any
                           agreements under terms of which the operating company
                           is obligated to commit funds in order to maintain the
                           financial viability of a non-utility affiliate.

                  (3)      An AEP operating company shall not make any
                           investment in a non-utility affiliate under
                           circumstances in which the operating company would be
                           liable for the debts and/or liabilities of the
                           non-utility affiliate incurred as a result of acts or
                           omissions of a non-utility affiliate.

                  (4)      An AEP operating company shall not issue any security
                           for the purpose of financing the acquisition,
                           ownership, or operation of a non-utility affiliate.

                  (5)      An AEP operating company shall not assume any
                           obligation or liability as guarantor, endorse,
                           surety, or otherwise in respect of any security of
                           a non-utility affiliate.

                  (6)      An AEP operating company shall not pledge, mortgage
                           or otherwise use as collateral any assets of the
                           operating company for the benefit of a non-utility
                           affiliate.

         An AEP operating company may not incur debt in a manner that, on its
         default, would permit a creditor to have recourse against the assets of
         another AEP operating company.

                  Transactions between AEP operating companies and affiliates
                  involving a money pool for financing the short-term funding
                  requirements or transactions between AEP operating companies
                  and special purpose financing entities used solely for the
                  purpose of financing utility assets are exempt from the
                  requirements of this paragraph. Further, provisions of this
                  paragraph would not preclude the AEP operating companies from
                  issuing securities or assuming obligations related to their
                  coal subsidiaries.

                                       11

         F.       Any good or service provided by a non-utility affiliate to an
                  AEP operating company shall be by itemized billing statement
                  pursuant to a written contract or written arrangement. The
                  operating company and non-utility affiliate shall maintain
                  and, upon request, make available for inspection in Austin,
                  Texas by the PUCT, copies of each billing statement, contract
                  and arrangement between the operating company and its
                  non-utility affiliates that relates to the provision of such
                  goods and services in accordance with applicable PUCT document
                  retention requirements.

         G.       Employees responsible for the day to day operations of the AEP
                  operating companies and those of affiliated exempt wholesale
                  generators or affiliated power marketers shall operate
                  independently of one another. AEP shall track and document all
                  employee movement between and among all affiliates. Such
                  information shall be made available to the PUCT and consumer
                  advocates upon request. Employees may transfer from one
                  function to the other so long as the transfer does not create
                  any unfair competitive advantage to the AEP operating company
                  or the affiliated exempt wholesale generator or affiliated
                  power marketer.

         H.       An AEP operating company may not own property in common with
                  an affiliated exempt wholesale generator or affiliated power
                  marketer.

         I.       No market information obtained in the conduct of utility
                  business may be shared with an affiliated exempt wholesale
                  generator or affiliated power marketer, except where such
                  information has been publicly disseminated or simultaneously
                  shared with and made available to all non-affiliated entities
                  who have requested such information. Customer specific
                  information shall not be made available to an affiliated
                  exempt wholesale generator or affiliated power marketer except
                  under the same terms as such information would be made
                  available to a non-affiliated company, and only with the
                  written consent of the customer specifying the information to
                  be released.

         J.       An affiliate may use an AEP operating company's name or logo
                  only if, in connection with such use, the affiliate makes
                  adequate disclosures to the effect that (i) the two entities
                  are separate; (ii) it is not necessary to purchase the
                  non-regulated product or service to obtain service from the
                  operating company; and (iii) the customer will gain no
                  advantage from the operating company by buying from the
                  affiliate.

         K.       An AEP operating company shall not condition or tie the
                  provision of any product, service, pricing benefit, or waiver
                  of associated terms or conditions, to the purchase of any good
                  or service from its affiliated exempt wholesale generator or
                  power marketer.

                                       12
<PAGE>   18
         L.       Except as provided in paragraph M, an affiliated exempt
                  wholesale generator or affiliated power marketer shall not
                  share office space, office equipment, computer systems or
                  information systems with an AEP operating company.

         M.       Computer systems and information systems may be shared between
                  an AEP operating company and non-utility affiliates only to
                  the extent necessary for the provision of corporate support
                  services; however, the operating company shall ensure that the
                  proper security access and other safeguards are in place to
                  ensure full compliance with these affiliate rules.

         N.       The provision of corporate support services shall not allow or
                  provide a means for the transfer of confidential information
                  from the operating company to the affiliate, create the
                  opportunity for preferential treatment or unfair competitive
                  advantage, create opportunities for cross-subsidization of
                  affiliates, or otherwise provide any means to circumvent these
                  affiliate rules.

         O.       Except as provided in paragraph M, an AEP operating company
                  may only make a product or service available to an affiliate
                  exempt wholesale generator or an affiliated power marketer if
                  the product or service is equally available to all
                  non-affiliated exempt wholesale generators and power marketers
                  on the same terms, conditions and prices, and at the same
                  time. An AEP operating company shall process all requests for
                  a product or service from affiliated and non-affiliated exempt
                  wholesale generators and power marketers on a
                  non-discriminatory basis.

         P.       An AEP operating company which provides both regulated and
                  non-regulated services or products, or an affiliate which
                  provides services or products to an AEP operating company,
                  shall maintain documentation in the form of written
                  agreements, an organization chart of AEP (depicting all
                  affiliates and AEP operating companies), accounting bulletins,
                  procedure and work order manuals, or other related documents,
                  which describe how costs are allocated between regulated and
                  non-regulated services or products. Such documentation shall
                  be available, subject to requests for confidential treatment,
                  in a central location for review by the PUCT and municipal
                  regulatory authorities.

         Q.       Except as provided in the Public Utility Regulatory Act,
                  including, but not limited to Subchapter B of Chapter 35, all
                  transfers of utility property with a net book value of more
                  than $1 million to unregulated affiliates must be valued at
                  the higher of net book value or market value for ratemaking
                  purposes, and all transfers of affiliate property with a net
                  book value of more than $1 million to regulated utilities must
                  be valued at the lesser of net book value or market value for
                  ratemaking purposes. This provision shall not apply to sales
                  of accounts receivable.

         R.       Transfers of generation, transmission, and fuel regulated
                  assets allowed by applicable utility industry restructuring
                  legislation or regulatory requirements are not subject to
                  subparagraph Q. For retail rate-making purposes, the cost

                                       13
<PAGE>   19
                  characteristics of such generation, transmission or fuel
                  related assets shall be preserved for the duration of cost
                  based regulation of such transferred assets. Treatment of any
                  loss or gain from the sale of such assets will be subject to
                  applicable accounting, regulatory and statutory requirements.

         S.       AEP shall designate an employee who will act as a contact for
                  the PUCT and consumer advocates seeking data and information
                  regarding affiliate transactions and personnel transfers. Such
                  employee shall be responsible for providing data and
                  information requested by the PUCT for any affiliate
                  transactions and personnel transfers which involve a
                  jurisdictional operating company, regardless of the
                  affiliate(s), subsidiary(is), associate(s) or AEP operating
                  company from which the information is sought.

         T.       AEP shall designate an employee or agent within Texas who will
                  act as a contact for retail consumers regarding service and
                  reliability concerns and to allow a contact for retail
                  consumers for information, questions and assistance. Such AEP
                  representative shall be able to deal with billing, maintenance
                  and service reliability issues.

         U.       AEP shall provide the PUCT a current list of employees or
                  agents that are designated to work with the PUCT concerning
                  state regulatory matters, including, but not limited to, rate
                  cases and retail competition issues.

         V.       Prior to filing any affiliate contract (including service
                  agreements) with the SEC or the FERC, and AEP operating
                  company shall submit to the PUCT a copy of the proposed
                  filing.

         W.       Any violation of the provisions of these affiliate standards
                  is subject to the enforcement powers and penalties of the
                  PUCT.

         X.       AEP shall contract with an independent auditor who shall
                  conduct biennial audits for eight years after merger
                  consummation of affiliated transactions to determine
                  compliance with these affiliate standards. The results of such
                  audit shall be filed with the PUCT. Prior to the initial
                  audit, AEP will conduct an informational meeting with the PUCT
                  regarding how its affiliates and affiliate transactions will
                  or have changed as a result of the proposed merger.

7.       Market Power Mitigation

         A.       System Integration Agreements. To mitigate any perceived
                  impacts of the merger on the Merged Company's market power,
                  the Applicants have proposed in their FERC Merger Application
                  a mitigation plan. To protect Texas retail customers, the
                  Merged Company agrees to hold harmless the retail customers of
                  the Texas operating companies from adverse net costs impacts
                  arising from the mitigation plan, as measured on a calendar
                  year basis.

                                       14

         B.       The Merged Company agrees to divest 1604 megawatts ("MW") of
                  generation capacity in ERCOT (Lon Hill Units 1-4 (CPL) - 546
                  MW, Nueces Bay Plan (CPL) - 559 MW, Joslin Unit 1 (CPL) - 249
                  MW, and Frontera Plan (CSW Energy) - 250 MW (as included in
                  Applicants' FERC mitigation plan). The divestiture shall be
                  timed so as not to violate the criteria for pooling of
                  interests accounting. Following execution of the Agreement,
                  Applicants and General Counsel shall jointly seek written
                  guidance (including appeals to the SEC, if available) from the
                  SEC or other entity authorized by the SEC to rule on this
                  matter, including, but not limited to, the Office of Chief
                  Accountant, on whether the divestiture of assets before two
                  years after consummation of the merger as proposed herein will
                  prevent pooling of interests accounting treatment for the
                  AEP/CSW merger.

                  Absent the Stipulation, General Counsel would have advocated,
                  and believed the PUCT would have ordered both the level and
                  the timing of the divestiture included within this
                  Stipulation.

                  Affiliates shall be ineligible to directly purchase divested
                  capacity, but may engage in non-firm energy transactions with
                  parties who purchase the capacity. The Signatories agree not
                  to oppose, consistent with any applicable electric industry
                  restructuring legislation, inclusion of these amounts of
                  divested capacity for purposes of compliance with future
                  statutes or rules requiring capacity auction or divestiture.

         C.       General Counsel and Applicants believe that current SEC
                  guidance allows the divestiture event to begin as soon as
                  possible after the effective date of the merger if the Merged
                  Company can demonstrate that the divestiture was required by
                  the PUCT and would have been ordered to occur in less than two
                  years if not for this settlement. The Merged Company agrees to
                  advocate this position in any meeting or proceeding before the
                  SEC in which the pooling of interests issue is considered. If
                  it is determined that divestiture can proceed immediately
                  without jeopardizing pooling of interests accounting treatment
                  for the merger, the divestiture shall begin no later than 90
                  days after the effective date of the merger. The Merged
                  Company further agrees to provide regular status reports to
                  the PUCT and all Signatory parties of the status of SEC
                  considerations of the merger, including, but not limited to,
                  the pooling of interests issue. If the SEC, through the
                  issuance of a final, non-appealable order or other final,
                  non-appealable ruling determines that the divestiture would be
                  a pooling violation, the auction will be scheduled consistent
                  with meeting SEC pooling of interests requirements. If the
                  final ruling from SEC will allow the divestiture of some of
                  the units within two years after the effective date of the
                  merger, the General Counsel and the Merged Company will work
                  together to determine the sequence of divestiture of those
                  units. If the General Counsel and the Merged Company are
                  unable to agree on the sequence of divestiture they will
                  submit the issue to the PUCT.

         D.       The terms of the divestiture will detail the right of CPL to
                  recall up to 1354 MWs of the divested capacity in accordance
                  with the following terms:

                  (1)      CPL may recall the capacity anytime during May
                           through September;

                  (2)      Any recall of capacity must be pre-scheduled at least
                           24 hours in advance with specific hours and MWs
                           nominated;

                  (3)      Hours nominated may not exceed 20% of the hours in a
                           year (i.e., 1752 hours); and

                  (4)      A minimum of four consecutive hours shall be
                           nominated for each day pre-scheduled.

         E.       If the acquirer of the divested CPL plants has to run the
                  plant(s) more than the nominated hours on the days in which
                  CPL preschedules or nominates energy due to operating
                  requirements, CPL agrees to offer the acquirer the heat rate
                  times the applicable fuel cost of such plan(s) for energy
                  received. Such additional hours shall not count toward the
                  limit of 1752 hours that may be nominated per year.
                  Alternatively, the acquirer is free to sell power above the
                  nominated amounts into the marketplace.

         F.       CPL will pay the acquirer(s) of its divested generation for
                  capacity during the May through September period at the level
                  embedded in CPL's current rates less seven months of operation
                  and maintenance expenses embedded in CPL's current rates. The
                  Merged Company will pay for nominated energy by multiplying an
                  agreed daily fuel market index by the heat rate of the
                  specific plant as agreed in the contract between the
                  acquirer(s) of the CSW plant(s) and the Merged Company.

         G.       During the other seven months of the year (i.e., October
                  through April). CPL may need to purchase power from the market
                  to replace the divested capacity (up to 1354 MWs). The energy
                  portion of the purchased power will be included in CPL's
                  reconcilable fuel expense at a fixed heat rate of 10,000
                  multiplied by the applicable monthly average price paid by CPL
                  for natural gas for each month such energy portion was
                  purchased during the reconciliation period. The cost of
                  replacement capacity will be subtracted from the reduction in
                  CPL's base rate revenue requirement due to divestiture in
                  order to determine the net reduction in revenue requirement
                  resulting from the divestiture. This amount is identified by
                  the following formula:

                           A + B - C + D

                  where:

                  A =      seven-twelfths of the operation and maintenance
                           expense of the divested plants, as recorded in the
                           1998 FERC Form 1 for CPL;

                                       16
<PAGE>   22
                  B =      reduction in annual depreciation and pre-tax return
                           due to reducing the undepreciated balance of STP
                           plant by the amount of the gain from divestiture;

                  C =      replacement capacity cost for the October through
                           April period;

                  D =      annual net reduction in base rate revenue
                           requirement from divestiture.

                  One-half of any positive annual net reduction in base rate
                  revenue requirement resulting from divestiture, as "D" is
                  defined in the above formula, will be used to reduce the
                  undepreciated balance of South Texas Project ("STP") plant,
                  and the remainder will be retained by the Merged Company.

         H.       CPL's recall right will expire once there is no longer an
                  obligation to serve retail customers in ERCOT. The recall
                  right will be reduced to the extent that CPL no longer remains
                  legally obligated to serve any retail customer or group of
                  retail customers, either existing or prospective. To the
                  extent that CPL retains the legal obligation to serve any
                  existing or prospective retail customer or group of retail
                  customers, the load requirements of those customers shall be
                  considered in determining whether the right of recall shall be
                  reduced. An example of how this calculation will be done under
                  currently proposed deregulation legislation is attached as
                  Attachment G.

                  In the event that future statutes require that the PUCT
                  designate a provider of last resort which must offer service
                  to all customers within all or designated portions of CPL's
                  service area, and in the event that CPL affirmatively requests
                  that it be so designated, the load requirements for those
                  customers eligible for service from CPL as a provider of last
                  resort shall not be considered as load requirements of retail
                  customers for whom CPL retains a legal obligation to serve,
                  solely for purposes of determining whether the right of recall
                  shall be reduced. In the event that CPL does not affirmatively
                  request designation as a provider of last resort within its
                  service area but is so designated by the PUCT, the load
                  requirements of retail customers eligible for service from CPL
                  as a provider of last resort shall be considered as load
                  requirements of retail customers for whom CPL retains a legal
                  obligation to service for purposes of determining whether the
                  right of recall shall be reduced.

         I.       The Merged Company agrees to divest 300 MW in SPP. No further
                  SPP divestiture is required.

         J.       Gains from the sale of the Lon Hill, Nueces Bay and Joslin
                  plants shall be utilized to reduce STP excess costs over
                  market ("ECOM"), taking into account the effects of income
                  taxes and reasonable transaction costs. The amount of such
                  gains will be deducted from the ECOM asset determined by the
                  Commission's Final Order on Rehearing in Docket No. 14965. At
                  the time of CPL's next base rate proceeding, if industry
                  restructuring legislation has not been adopted, then the
                  parties agree that the annual amortization of ECOM will be
                  reduced proportionately. The period over which the remaining
                  balance of ECOM, if any,

                                       17
<PAGE>   23
                  is to be amortized remains as ordered by the Commission's
                  Final Order on Rehearing in Docket No. 14965.

         K.       The Merged Company and Texas operating companies agree that no
                  ratepayer of a Texas operating company will be charged any new
                  or increased surcharge or PCRF to recover any capacity cost
                  resulting from divestiture provided for in Section 6 of this
                  Agreement. This provision does not prevent the Merged Company
                  from seeking recovery of capacity costs in accordance with
                  subparagraph 3.E of this Agreement which may be incurred
                  regardless of the divestiture of generating capacity required
                  by this Agreement.

         L.       Pursuant to the PUCT's statutory authority, CPL will submit
                  the terms of the divestiture of its plants to the PUCT for
                  approval.

         M.       Prior to December 31, 2000, the Applicants agree that AEP will
                  file with the FERC an unconditional application to, consistent
                  with the Regional Transmission Organization ("RTO") agreement,
                  transfer the operational control of bulk transmission
                  facilities owned, controlled and/or operated by AEP currently
                  located in the SPP to a FERC-approved RTO directly
                  interconnected with the AEP transmission facilities. The above
                  date is extended, if necessary, to 75 days after FERC issues
                  the order on an RTO to which AEP is a signatory that is filed
                  before June 30, 2000. Applicants agree to pursue any FERC
                  filings made pursuant to this paragraph in good faith using
                  their best efforts to obtain prompt FERC approval.

7.       Quality of Service

         A.       Customer Service Standards.

                  These guidelines establish customer service performance
                  standards that should be achieved by the Merged Company. The
                  Merged Company shall make measurements to determine the level
                  of service quality for each item included in these guidelines.
                  The Merged Company shall provide the PUCT with the
                  measurements and summaries thereof for any of the items
                  included herein on request of the PUCT. Records of these
                  measurements and summaries shall be retained by the Merged
                  Company.

                  (1)      Service Turn On and Upgrades: On a quarterly basis,
                           the Merged Company shall complete the installation of
                           new service or upgrade of service as follows:

                           (a)      Ninety-five percent of new service
                                    installations requiring no construction of
                                    electric facilities shall:

                                       18
<PAGE>   24
                                    (i)     be completed within 24 hours after
                                            the customer's service location is
                                            ready for service and all necessary
                                            tariff requirements have been met;

                                    (ii)    be completed by the requested
                                            installation date, when an applicant
                                            requests an installation date more
                                            than 24 hours after the customer's
                                            service location is ready for
                                            service and all necessary tariff
                                            requirements have been met.

                           (b)      Ninety percent of new service installations
                                    requiring construction of electric
                                    facilities, including the setting of the
                                    meter, and ninety percent of service
                                    upgrades, shall:

                                            after the customer's service
                                            location is ready for service and
                                            all necessary tariff and local
                                            regulation requirements have been
                                            met;

                                    (ii)    be completed by the requested
                                            installation date, when an applicant
                                            or customer requests an installation
                                            date more than ten business days
                                            after the customer's service
                                            location is ready for service and
                                            all necessary tariff requirements
                                            have been met;

                                    (iii)   provided that this standard shall
                                            not apply to an extension that
                                            involves the construction of
                                            non-standard facilities.
                                            Non-standard conditions for
                                            extension requirements are
                                            characterized by one of the
                                            following factors: (a) the service
                                            installation requires underground
                                            feeder construction of more than
                                            300 feet in length or (b) the
                                            service installation requires
                                            construction of more than 1320 feet
                                            of single phase line in the service
                                            area of WTU, or more than 900 feet
                                            of single phase line in the service
                                            areas of CPL or SWEPCO.

                                            Service installation requiring line
                                            extensions that involve
                                            non-standard facilities shall be
                                            completed within ninety (90) days,
                                            unless circumstances beyond the
                                            Company's control cause unavoidable
                                            delays;

                                     (iv)   provided, further, that this
                                            standard will be tolled for all
                                            requests for service for the
                                            duration of any "major event" as
                                            defined in Substantive Rule
                                            25.52(c)(2)(D).

                           c.       If an applicant/customer complies with all
                                    pertinent tariff requirements and the
                                    electric distribution company cannot
                                    complete the requested service installation
                                    or service upgrade as

<PAGE>   25
                                    set forth above, the company shall promptly
                                    notify the applicant/customer of the delay,
                                    the reasons for the delay, the steps being
                                    taken to complete the work, and the probable
                                    completion date. If such probable completion
                                    date cannot be met, repeat notification
                                    shall be made.

                           d.       Penalty for failure to meet this standard:
                                    the Merged Company will rebate, on a
                                    quarterly basis, via bill credit $40 for
                                    each customer not connected within the time
                                    frames stated above.

                  (2)      Light Replacements. In any distribution substation
                           service area, 95 percent of all customer reports of
                           security and streetlight outages shall be corrected
                           within 72 hours. Light replacement compliance will be
                           measured on a calendar month basis. This standard
                           will be tolled for all customer reports for the
                           duration of any "major event," as defined in
                           Substantive Rule 25.52(c)(2)(D).

                  (3)      Telephone Response. On an annual basis, the call
                           center's average answer time for customer calls shall
                           not exceed sixty seconds.

                           a.       As used in this paragraph, "answer" means
                                    the operator, service representative, or
                                    automated system is ready to render
                                    assistance and/or accept the information
                                    necessary to process the call.

                           b.       Answer time shall be measured from the first
                                    ring at the call center or at the point the
                                    customer begins to wait in queue, whichever
                                    comes first.

                           c.       If the Merged Company utilizes a menu
                                    driven, automated, interactive answering,
                                    the initial recorded message presented by
                                    the system to the customer shall only
                                    identify the company and the general options
                                    available to the customer, including the
                                    option of being transferred to a live
                                    attendant. At any time during the call, the
                                    customer shall be transferred to a live
                                    attendant if the customer fails to interact
                                    with the system for a period of ten seconds
                                    following any prompt.

                           d.       Customers shall not be delayed from reaching
                                    the queue by any promotional or
                                    merchandising material not selected by the
                                    customer.

                           e.       Performance data during a "major event" (as
                                    such term is defined in Substantive Rule
                                    25.52(c)(2)(D)) or comparable term as such
                                    is used by the electric distribution company
                                    in its emergency plan, and subject to review
                                    and acceptance by the PUCT, shall be

                                    excluded from the calculation of annual
                                    minimum service value pursuant to this
                                    subparagraph (3).

                           f.       Penalty for failure to meet this standard.
                                    The Merged Company will rebate, via a bill
                                    credit, on an annual basis, $20 for each
                                    verifiable customer who does not receive
                                    service within the standard's parameters,
                                    limited to one $20 credit per customer per
                                    month of service. For customers who cannot
                                    be verified, the Merged Company will
                                    contribute the $20 to a fund to benefit
                                    low-income customers.

                  (4)      Reporting requirements.

                           a.       When the Merged Company does not meet any
                                    minimum service standards concerning
                                    Response to Request for Service and Customer
                                    Service Call Center for any two months
                                    within any twelve-month period, the company
                                    shall notify the PUCT Office of Customer
                                    Protection in writing within fifteen days
                                    after internal measurements have disclosed
                                    such failure. The company shall submit a
                                    report of any remedial action taken to the
                                    Office of Customer Protection within an
                                    additional thirty days.

                           b.       The Merged Company shall conduct
                                    statistically valid customer service surveys
                                    of Texas customers annually. The results of
                                    the survey shall be compiled by the utility
                                    and reported to the PUCT Office of Customer
                                    Protection under confidential or other
                                    protected designations if required to
                                    protect sensitive information.

                           c.       The Merged Company shall submit an Annual
                                    Customer Service Report to the PUCT Office
                                    of Consumer Protection that addresses
                                    customer service issues such as number of
                                    customer complaints, performance of the call
                                    center, performance of field personnel,
                                    billing error rates, etc.

                           d.       The Merged Company shall provide an Annual
                                    Utility Scorecard to its customers that
                                    addresses issues such as number of customer
                                    complaints, performance of the call center,
                                    performance of field personnel, billing
                                    error rates, etc.

                           e.       The Merged Company shall maintain records
                                    sufficient to demonstrate compliance with
                                    these standards and shall provide such
                                    records to the PUCT upon request.

         B.       Reliability. The intent of the reliability provisions set out
                  below is for the Merged Company to comply with the provisions
                  of the PUCT rules adopted in Project No. 19198.

                  (1)      General Provisions.

                           a.       The standards are to be consistent with PUCT
                                    Substantive Rule 25.52 (Reliability and
                                    Continuity of Service).

                           b.       Reporting periods are to be consistent with
                                    PUCT Substantive Rule 25.81 (Service Quality
                                    Reports) and are to coincide with the
                                    Applicants' Electric System Service Quality
                                    Report to the PUCT. Annual evaluations will
                                    be for the 12-month period ending April 30
                                    of each year. Initial evaluation will be for
                                    the reporting period ending April 30, 2001.

                           c.       Reliability indices are calculated for
                                    "forced interruptions" unless otherwise
                                    specified.

                           d.       The standards will be calculated and
                                    evaluated separately for the Texas
                                    operations of each CSW operating company
                                    (CPL, SWEPCO and WTU).

                  (2)      90% Distribution Feeder Standards. The following
                           reliability standards for System Average Interruption
                           Frequency Index ("SAIFI") and System Average
                           Interruption Duration Index ("SAIDI") shall be
                           established for distribution feeders for each CSW
                           operating company:

                           a.       Standards shall be established for the
                                    24-month period ending April 30, 1999. The
                                    standards shall be the average of the 1998
                                    and the 1999 reporting years for each index
                                    at the value represented by the 10% of the
                                    distribution feeders with the highest
                                    values.

                           b.       Reliability of distribution feeders
                                    performing below the standard shall be
                                    improved, resulting in 96% of the feeders
                                    performing at or better than the standard in
                                    the 2001 reporting period.

                  (3)      2% Distribution Feeder Standards. Each CSW operating
                           company shall manage its distribution feeders so that
                           no distribution feeder shall sustain 12-month SAIDI
                           or SAIFI values that are among the highest (worst)
                           2.0% of that company's feeders for two or more
                           consecutive reporting years.

                  (4)      System Standards. System-wide service reliability
                           standards shall be established for each CSW operating
                           company as follows:

                           a.       SAIFI Standard - System Average Interruption
                                    Frequency Index Average SAIFI for 3-year
                                    reporting period 5/1/97-4/30/00.

                  b.       SAIDI Standard - System Average Interruption Duration
                           Index Average SAIDI for 3-year reporting period
                           5/1/97-4/30/00.

                  c.       As of April 30, 2001, maintain annual system-wide
                           SAIFI and SAIDI values at or better than 105% of the
                           standard.

         (5)      Guarantees to Meet Reliability Standards.

                  a.       The Annual service reliability guarantees for the CSW
                           operating companies will be as follows:

</TABLE>

                  b.       The guarantees will be credited to customers based
                           upon the following priorities:

                           (i)      90% Distribution Feeder Standards;

                           (ii)     2% Distribution Feeder Standards;

                           (iii)    System Standards.

                  c.       Terms of Guarantees:

                           (i)      90% Distribution Feeder Standards

                                    (a)      A service reliability credit of $20
                                             shall be made to each customer on
                                             all feeders violating the 96%
                                             provision of the rule. (For
                                             example, if only 95% of the feeders
                                             perform at or better than the 90%
                                             standard, a credit will be made to
                                             customers on 5% of the feeders.) A
                                             separate credit will be made for
                                             each standard violated (SAIDI and
                                             SAIFI) such that a customer on a
                                             feeder violating both standard
                                             would be credited $40. This credit
                                             will not be made for feeders that
                                             perform at the system average times
                                             two. The sum of these credits will
                                             not exceed the maximum amount of
                                             the service reliability guarantees
                                             stated above.

                                    (b)      If a CSW operating company achieves
                                             the SAIDI and/or SAIFI 90%
                                             Distribution Feeder Standards for a
                                             reporting period (i.e., 96% of the
                                             feeders perform at or better than
                                             the 90% standard), the

<PAGE>   29
                                             total amount of guarantees will be
                                             reduced in the following amounts
                                             for each standard achieved: CPL,
                                             $357,000; SWEPCO, $83,500; and WTU,
                                             $59,500 (which total $500,000)
                                             (such that the amount of the
                                             reduction will be equal to twice
                                             that amount if both standards are
                                             achieved). The reduction of
                                             guarantees will decrease the
                                             exposure the operating company may
                                             have with respect to the 90%
                                             Distribution Feeder Standards, the
                                             2% Distribution Feeder Standards or
                                             the System Standards for that
                                             reporting year.

                           (ii)     2% Distribution Feeder Standards.

                                    (a)      A service reliability credit of $50
                                             shall be made to each customer on a
                                             feeder violating either standard. A
                                             separate credit will be made for
                                             each standard violated (SAIDI
                                             and/or SAIFI) such that a customer
                                             on a feeder violating both
                                             standards would be credited $100.
                                             These credits will be prorated if
                                             the guarantees for this provision
                                             plus the guarantees for the 90%
                                             Distribution Feeder Standard exceed
                                             the total guarantees expressed
                                             above as calculated for each CSW
                                             operating company.

                                    (b)      If a CSW operating company achieves
                                             the SAIDI and/or SAIFI 2%
                                             Distribution Feeder Standards for a
                                             reporting period (i.e., no feeders
                                             repeat on the 2% list), the total
                                             amount of guarantees will be
                                             reduced in the following respective
                                             amounts for each standard achieved:
                                             CPL, $357,000; SWEPCO, $83,500; and
                                             WTU, $59,500 (which total $500,000)
                                             (such that the amount of the
                                             reduction will be equal to twice
                                             that amount if both standards are
                                             achieved). The reduction of
                                             guarantees will decrease the
                                             exposure the operating company may
                                             have with respect to the 2%
                                             Distribution Feeder Standards or
                                             the System Standards for the
                                             reporting year.

                           (iii)    System Standards. In the event an operating
                                    company's system SAIDI and/or SAIFI values
                                    exceed the allowable limit of 105% of the
                                    36-month standard described above, the
                                    company shall credit the guarantees
                                    proportionately among all customers on the
                                    company's Texas system as follows:

                                             actual and allowable SAIDI values
                                             (measured in minutes) multiplied by
                                             10,000, up to a maximum of the
                                             lower of (i) the total remaining
                                             guarantee described above for each

                                             (which total $1.05 million, or 25%
                                             of the total guarantee described
                                             above).

                                    (b)      SAIFI: The guarantee will be the

                                             (ii) the following amounts for each

                                             SWEPCO, $175,350; and WTU, $124,950
                                             (which total $1.05 million, or 25%
                                             of the total guarantee described
                                             above).

                                    (c)      If a CSW operating company achieves
                                             either the SAIDI or SAIFI System
                                             Standard for a reporting period
                                             (i.e., performance at or below 105%
                                             of the standard), the amount of the
                                             guarantees will be reduced in the
                                             following amounts: CPL, $357,000;
                                             SWEPCO, $83,500; and WTU, $59,500
                                             (which total $500,000). The
                                             reduction of guarantees will
                                             decrease any exposure the operating
                                             company may have with respect to
                                             the other System Standard for that
                                             reporting year.

         C.       PUCT Office of Customer Protection ("OCP") audit.

                  Twenty-four months after the customer service objectives and
                  performance standard levels are implemented by the Merged
                  Company, and every twenty-four months thereafter, the PUCT
                  Office of Customer Protection shall conduct an independent
                  audit to determine whether the proposed performance standards
                  have been implemented.

                  The PUCT Office of Customer Protection shall file a report
                  detailing any areas where the Merged Company did not
                  accurately report instances where the performance standard
                  levels were not met, or failed to accurately account for every
                  penalty required by these guidelines.

         D.       Term of Standards.

                  (1)      The customer service standards established under this
                           agreement shall remain in effect for a period of six
                           (6) years following the effective date of the merger.
                           Reporting periods for all standards will coincide
                           with the Electric System Service Quality Report to
                           the Commission. The initial evaluation will be for
                           the reporting period ending April 30, 2001.

                  (2)      Any interested person shall have the right to
                           petition the Commission to revise the standard and/or
                           penalties described herein. In the event the
                           Commission's service reliability rule (Substantive
                           Rule 25.52) is amended, such amendments shall
                           automatically be incorporated in this agreement.
                           Additionally, the signatories agree that they will
                           revisit these standards and penalties in the future
                           in the context of any performance-based ratemaking
                           plans or rules for CSW and/or the electric industry.

8.       Low Income Program. The Merged Company commits to the Low-Income
         Program described below for six years, until the next base rate case of
         each operating company, or until the Low-Income Program is evaluated in
         accordance with provisions of restructuring legislation. The PUCT will
         have the ability to review the Low-Income Program in accordance with
         the next base rate case of each operating company or in accordance with
         the provisions of restructuring legislation and may continue such
         programs to the extent cost recovery is provided.

         A.       CPL, SWEPCO and WTU commit to continue funding of low-income
                  DSM programs at current levels for the full six-year term of
                  the merger savings sharing plan unless otherwise revised by
                  the PUCT.

                  Current HomeSavers program funding commitments:
<TABLE>
<S>                                 <C>
                  CPL               $1,365,000
                  SWEPCO               400,000
                  WTU               $  325,000
                                   ------------
                  Total             $2,090,000
</TABLE>

                  Funds not utilized by the HomeSavers program during the
                  current contract year and in future years shall be carried
                  forward during the six-year merger savings sharing period.

         B.       Each operating company shall conduct an annual review meeting
                  for low-income program expenditures and to recommend any
                  changes in program design and outreach. Representative of the
                  PUCT, the Low-Income Intervenors and OPC will participate in
                  the annual meeting. Interim spending reports for low-income
                  programs shall be provided on a quarterly basis to PUCT staff,
                  Low-Income Intervenors and OPC.

                                       26
<PAGE>   32
        C.        CPL, SWEPCO and WTU shall each commit an additional annual
                  budget of $100,000 to unspecified low-income DSM programs
                  approved by the Commission. Representatives of the Commission,
                  Low Income Intervenors and OPC shall be given an opportunity
                  to participate in formulating a list of low-income DSM
                  programs recommended for Commission approval. These funds will
                  be used for DSM programs to benefit low-income customers
                  living in public housing, Section 8 multifamily housing,
                  housing funded by Habitat for Humanity, homeless shelters, and
                  any other energy efficiency programs that benefit low-income
                  customers.

         D.       CPL and SWEPCO will continue their Neighbor to Neighbor
                  programs that provide billing assistance to low-income
                  customers. WTU shall implement a Neighbor to Neighbor program.
                  WTU will work with Texas Legal Services Centre to implement
                  such a program through a third party administrator.

                  Minimum annual funding for each Neighbor to Neighbor program
                  shall be as follows:

<TABLE>
<S>                                 <C>
                  CPL               $250,000
                  SWEPCO            $100,000
                  WTU               $100,000
                                   ----------
                                    $450,000
</TABLE>

                  These minimum-funding levels will be in addition to any
                  customer contributions to the programs.

9.       Other Provisions

         A.       Pending rate litigation will be resolved as provided in
                  Attachment H. Each individual year's rate reduction will apply
                  for a twelve month period following the effective date of the
                  merger with the last decrease continuing to apply in years
                  following the end of year six until base rates for the Texas
                  operating company are changed.

         B.       The Merged Company commits and agrees that:

                  (i)      upon issuance of any final and non-appealable order
                           from the FERC, SEC, or any state or federal
                           commission addressing the merger, through stipulation
                           or otherwise; and

                  (ii)     upon execution of any written agreement settling
                           merger issues, any of which provide merger benefits
                           to ratepayers of any jurisdiction or impose merger
                           conditions on the Merged Company that would benefit
                           the ratepayers of any jurisdiction, such set benefits
                           and conditions will be extended to Texas retail
                           customers to the extent necessary to achieve
                           equivalent net benefits and conditions to the Texas
                           retail customers,

                                       27
<PAGE>   33
                           provided the proposed merger is ultimately
                           consummated. The Merged Company will file with the
                           PUCT and provide all Signatories a copy of all final
                           orders from all jurisdictions, and serve all executed
                           settlement agreements on General Counsel, within 10
                           days of execution of the same. Any action by a
                           Signatory to enforce the most favored nations
                           provision of this stipulation will not trigger any
                           rate treatments illustrated in Attachment F, and the
                           Attachments A and H rate credits will remain in
                           place.

         C.       Excluding positions at the three divested plants after the
                  date of divestiture, the Merged Company will freeze operating
                  company field positions and customer service jobs for eighteen
                  months from April 1, 1999. The Merged Company will not make
                  any terminations, layoffs, or reassignments, unless the
                  reassignment is to Central and South West Services, Inc.
                  ("CSWS") or its successor and the employee performs the same
                  job as before the reassignment, except for CSWS or its
                  successor rather than for the operating company.

         D.       If electric utility restructuring legislation is adopted, the
                  Merged Company commits to file a one-time customer Education
                  Program with the PUCT for approval by the OCP within 90 days
                  of the effective date of the merger or the legislation,
                  whichever is later. The Customer Education Program will be
                  designed to provide information about electric industry
                  restructuring and retail competition. The program will be
                  designed and implemented for all of the Merged Company's Texas
                  customers. The program will include, but is not limited to, an
                  Internet web site, mailers which include information such as
                  frequently asked questions and answers, newspaper articles,
                  press releases, and advertisements. The Merged Company should
                  spend an amount up to $750,000 per year for two years on the
                  customer Education Program. The Signatories agree not to
                  oppose, to the extent consistent with any applicable electric
                  industry restructuring legislation, inclusion of these amounts
                  of customer education expenditures for purposes of compliance
                  with future statutes or rules requiring consumer education
                  advertising.

         E.       This agreement is binding on the Office of the Attorney
                  General only in its capacity as a representative of state
                  agencies as consumers of electric service. By signing this
                  agreement, the State of Texas is in no way waiving any of its
                  rights or settling any potential claims pursuant to the Texas
                  Free Enterprise and Antitrust Act of 1983, TEX. BUS. & COM.
                  CODE Sections 15.01-.52.

                  The approval of this Integrated Stipulation and Agreement by
                  the Steering Committee of the Cities of Corpus Christi,
                  McAllen, Victoria, Big Lake, Paducah and Vernon is conditioned
                  to the right of individual cities to reconsider their prior
                  approval of the November 3, 1998 Stipulation and Agreement and
                  reject the Integrated Stipulation and Agreement within thirty
                  (30) days of the execution of this document.

                                       28

         F.       The Merged Company commits to coordinate transmission and
                  distribution substation planning with transmission dependent
                  utilities to provide reliable service, to maximize use of
                  existing facilities, and to avoid expenditures for duplicative
                  facilities. The process will include:

                  (1)      Period meetings to discuss requirements for
                           facilities that are mutually beneficial;,

                  (2)      A commitment by the Merged Company to provide
                           resources and information to the appropriate regional
                           ISO or regulatory authority to assist in their
                           evaluations of facility requirements; and

                  (3)      An opportunity to utilize alternative dispute
                           resolution processes, as defined either by PUCT rules
                           (within ERCOT) or SPP tariffs or procedures (within
                           the SPP) or by the procedures of future entities
                           which exercise operational control over the
                           transmission systems.

         G.       The Merged Company will maintain a bargaining and
                  decision-making presence in the current CSW region with
                  authority to negotiate, deal and enter into binding agreements
                  with its present and potential Texas wholesale and
                  transmission customers (including interconnection agreements).
                  The threshold for such authority will be at least $3 million.

         H.       The Merged Company and the Texas operating companies may
                  consider increasing the level of contributions to low income
                  programs so long as the contributions do not adversely affect
                  the rate credits and reductions agreed to in this proceeding
                  or result in any new surcharge or PCRF or an increase in any
                  existing surcharge or PCRF.

         I.       The Merged Company and Texas operating companies will create
                  an internal accounting mechanism to reflect AEP use of
                  existing CSW sulfur dioxide ("SO2") allowances. Such use will
                  be valued at market value and gains and losses realized in
                  comparison to original cost of allowances in excess of amounts
                  included in base rates will be reflected as reconcilable fuel
                  costs. SO2 allowance transactions among existing AEP operating
                  companies will be as per existing agreements.

         J.       The Merged Company commits and agrees that the cost of capital
                  as reflected in CPL's, WTU's, and SWEPCO's rates shall not be
                  increased or adversely affected as a result of AEP's
                  acquisition of CSW. The Merged Company also agrees that
                  subsequent to the completion of the merger, the cost of
                  capital for CPL, WTU and SWEPCO should be set commensurate
                  with the risk of those utilities and should not be affected by
                  the merger. The Merged Company agrees that it will not oppose,
                  in either a regulatory proceeding or an appeal, the
                  application of the principle that the determination of the
                  cost of capital can be based on the risk attendant to the
                  regulated operations of CPL, WTU and SWEPCO.

                                       29

         K.       The Merged Company has no plans to liquidate, sell, merge, or
                  consolidate any Texas operating company or to materially
                  change any Texas operating company's investment policy,
                  business or corporate structure, or management. The Merged
                  Company agrees that the Texas operating companies will
                  continue to operate subject to the jurisdiction and regulation
                  of the PUCT after closing of the proposed merger. The Merged
                  Company agrees that the financial stability of the Texas
                  operating companies will not be impaired or jeopardized by the
                  merger and the interests of Texas customers will not be
                  prejudiced as a result of the merger. Nothing in this
                  agreement shall be construed to limit whatever rights the
                  Merged Company may have under applicable Texas law to
                  liquidate, sell, merge, or consolidate any Texas operating
                  company or to materially change any Texas operating company's
                  investment policy, business or corporate structure, or
                  management subject to required regulatory approvals.

         L.       The Merged Company shall provide written notice on the day of
                  closing to the Signatories and non-opposing parties that the
                  merger closing has occurred.

         M.       Any and all exhibits and testimony submitted by Signatories in
                  this docket will be offered for the purpose of supporting this
                  Agreement. Signatories reserve their full rights to challenge
                  any and all exhibits and testimony offered in this proceeding
                  by any party for any purpose other than support of this
                  Agreement. This includes the right to object to the admission
                  of such evidence and the right of cross-examination.

         N.       This Agreement is binding on each Signatory only for the
                  purpose of settling the issues herein and for no other
                  purpose. The Signatories acknowledge and agree that a
                  Signatory's support of the matters contained in this Agreement
                  may differ from its position or testimony in other dockets and
                  cases not referenced in this Agreement. To the extent that
                  there is a difference, a Signatory does not waive its position
                  in such other dockets. Because this is a settlement agreement,
                  a Signatory is under no obligation to take the same position
                  as set out in this Agreement in other dockets not referenced
                  in this Agreement whether those dockets present the same or a
                  different set of circumstances. The Signatories reserve their
                  rights in this docket to litigate all issues in this docket
                  against parties who do not sign this Stipulation.

         O.       This Agreement represents a compromise, settlement and
                  accommodation among the Signatories, and all Signatories agree
                  that the terms and conditions herein are interdependent and no
                  Signatory shall be bound by any portion of this Agreement
                  outside the context of the Agreement as a whole. If the PUCT
                  does not accept this Agreement in any material respect as
                  issued, the Signatories agree that any Signatory adversely
                  affected by that material modification or inconsistency has
                  the right to withdraw its consent from this Agreement, thereby
                  becoming released from all commitments and obligations, and to
                  proceed to hearing on all issues, present evidence, and
                  advance any positions it desires as if it had not been a
                  Signatory. If the PUCT does not adopt appropriate orders
                  consistent with the material terms of this Agreement, the
                  Signatories agree that neither oral nor

                                       30
<PAGE>   36
                  written statements made during the course of the settlement
                  negotiations, nor the terms of this Agreement may be used as
                  an admission or concession of any sort nor as evidence in any
                  proceeding. This obligation shall continue and be enforceable,
                  even if this Agreement is terminated.

         P.       Implementation of the actions contemplated in this Agreement
                  is subject to PUCT approval of this Agreement and consummation
                  of the AEP/CSW merger.

         Q.       This Agreement expires six years from the effective date of
                  the merger.

         R.       Nothing in this Agreement shall limit the statutory power of
                  any regulatory authority to adjudicate a contested case
                  brought before it.

         S.       This written agreement contains the entire understanding and
                  agreement of the Signatories, supersedes all other written and
                  oral exchanges, or arrangements or negotiations among them or
                  their representatives with respect to the subjects contained
                  herein; and neither this Agreement, nor any of the terms of
                  this Agreement, may be altered, amended, waived, terminated,
                  discharged or modified, except by a writing properly executed
                  by the Signatories.

         T.       The Signatories mutually agree that they enter into this
                  Agreement for their exclusive benefit and the benefit of their
                  respective lawful successors. The Signatories agree that
                  nothing in this Agreement shall be construed to confer any
                  right, privilege or benefit on any person or entity other than
                  the Signatories and their respective lawful successors.

         U.       This Agreement assumes the legality of the treatments and
                  methodologies set out herein. Should any treatment or
                  methodology used be declared illegal by either the PUCT or a
                  court, the Signatories agree to negotiate in good faith to
                  substitute a treatment or methodology with the same economic
                  effect of that declared illegal.

         V.       The titles assigned to each Article are for convenience only,
                  are not part of this Agreement and shall not be considered in
                  the resolution of any dispute or question arising with respect
                  to this Agreement.

         W.       Each signing representative warrants that he or she is duly
                  authorized to sign this Agreement on behalf of the Signatory
                  he or she represents. Facsimile copies of signatories are
                  valid for purposes of evidencing execution.

         X.       The Signatories may sign individual signature pages to
                  facilitate the circulation and filing of the original of this
                  Agreement.

Note (a) Achieved savings are the reduction in cost of service from gross merger
savings as shown in Roberson Exhibit MDR-1.

                                            Integrated Stipulation and Agreement


         In the event that future statutes provide that, upon the commencement
to customer choice, CPL is not required to serve large commercial and industrial
customers having loads above 1000 KW (which at the current time constitutes 550
MW of load), that amount would be deducted from CPL's recall right of 1354 MW on
the date customer choice begins. Assuming CPL's large commercial and industrial
load does not change, CPL's buyback rights would be 804 MW (1354 MW - 550 MW).
However, if CPL is involuntarily designated as a provider of last resort and
under the new statute must offer a provider of last resort service to large
commercial and industrial customers, its recall rights would not be diminished
because it retains the legal obligation to serve those customers.

                                           Integrated Stipulation and Agreement
                                                                    Page 1 of 3

               Settlement of Pending and Potential Rate Litigation

1.    Additional rate decreases.  In addition to the merger related rate
      reduction riders and in consideration for the partial settlement of the
      currently pending appeal of the CPL rate order and in consideration for
      the full settlement of the currently pending appeal of the SWEPCO fuel
      reconciliation proceeding and to recognize that the WTU rate freeze
      expired in October 1998, the Merged Company agrees to implement rate
      reduction riders which reflect the rate reductions on Page 3 of this
      Attachment beginning on the first revenue month after the effective
      date of the merger.  Each rate decrease amount shown in Table H-1 on
      page 3 of this Attachment will be allocated to customer classes based
      upon base rate revenues and will be credited to customers based upon a
      percentage of monthly base rate charges as shown in H-1a.  Each rate
      decrease amount shown in Table H-2 on page 3 of this Attachment will be
      allocated to customer classes as shown on Table H-2a.  The rate
      reduction rider (Table H-1 of Attachment H) for each Texas operating
      company will cease upon the effective date of new base rates for such
      company established pursuant to Section 36.151 or Section 36.101,
      PURA.  In the absence of the establishment of new base rates for a
      Texas Operating Company during the six year period, the rate reduction
      rider (Table H-1) for each Texas Operating will continue to apply in
      the years following the end of year six until new base rates for such
      Texas Operating Company are established.  The supplemental rate
      reduction rider (Table H-2 of Attachment H) will remain in effect
      notwithstanding any base rate proceeding during the six year period
      after the effective date of the merger and will continue to apply in
      the years following the end of year six until base rates for the Texas
      Operating Company are changed.

      All rate reduction riders will be credited to customers in accordance with
      Attachment I.

2.    Within 30 days of the effective date of the merger, SWEPCO will withdraw
      its pending appeal of its fuel reconciliation proceeding in Docket No.
      17460 pursuant to the following provisions:

            a.    Approval by the PUCT of the settlement of Docket No. 19265
                  including all material provisions of the regulatory plan
                  consistent with Section 9.0. of the Stipulation;

            b.    Agreement by all Signatories to this Agreement except General
                  Counsel that they will not initiate a base rate proceeding
                  against SWEPCO which would result in a change in base rates
                  prior to January 1, 2001; and

            c.    Agreement by all Signatories to this Agreement that
                  transmission equalization payments and receipts for intra-CSW
                  System transactions will be treated as base rate items in
                  future proceedings for all Texas operating companies.
<PAGE>   50
3.    Within 30 days of the effective date of the merger, CPL will withdraw from
      its pending appeal of Docket No. 14965 all issues which pertain to Points
      of Error Nos. 15 and 16 in CPL's Third Motion of Rehearing filed with the
      PUCT (related to the lawfulness of the mandated glide path rate reductions
      in 1998 and 1999) pursuant to the following provisions:

            a.    Approval by the PUCT of the settlement of Docket No. 19265
                  including all material provisions of the regulatory plan
                  consistent with Section 9.0. of the Stipulation;

            b.    Agreement by all Signatories to this Agreement except General
                  Counsel that they will not initiate a base rate proceeding
                  against CPL which would result in the change in base rates
                  prior to January 1, 2001;

            c.    CPL will have the right to continue to litigate all issues in
                  its appeal other than those related to the mandated glide path
                  rate reductions; and

            d.    In consideration for the commitments made in this Attachment
                  H, CPL will extend the terms of the Docket No. 12820
                  Stipulation to include a pre-tax ECOM amortization of
                  $20,000,000 per year in 2000 and 2001 and a pre-tax ECOM
                  amortization of $5,000,000 per year in the years 2002 through
                  2005.

4.    All Signatories to this Agreement except General Counsel agree that they
      will not initiate a base rate proceeding against WTU which would result in
      a change in base rates to be effective prior to January 1, 2001.

5.    The annual base rate reduction amounts are net, "bottom-line" amounts not
      subject to any offset.

6.    The Texas operating companies agree to implement the above rate
      decreases in the manner and amounts described above notwithstanding any
      changes to the current regulatory structure in Texas or implementation
      of a legislatively-mandated rate freeze.  In the event the retail
      electric restructuring deregulation legislation is implemented in Texas
      including any required divestiture, unbundling or restructuring, the
      Texas operating companies agree to apply the regulatory plan's
      provisions to regulated rates of their customers.

7.    The Signatories agree that any legislatively mandated reductions or
      credits to base rates that are part of any retail electric deregulation
      legislation implemented in Texas shall not diminish or offset but shall be
      in addition to the base rate reductions established in this proceeding.

8.    In the event that future statutes provide that, upon the commencement
      to customer choice.  CPL is not required to serve large commercial and
      industrial customers having loads above 1000 KW (which at the current
      time constitutes 550 MW of load), that amount would be deducted from
      CPL's recall right of 1354 MW on the date customer choice begins.
      Assuming CPL's large commercial and industrial load does not change,
<PAGE>   51
      CPL's buyback rights would be 804 MW (1354 MW - 550 MW).  However, if
      CPL is involuntarily designated as a provider of last resort and under
      the new statute must offer provider of last resort service to large
      commercial and industrial customers, its recall rights would not be
      diminished because it retains the legal obligation to serve those
      customers.

           Principles for Texas Merger Retail Decrease Implementation


1.    Riders for each Company will be implemented annually to refund the
      negotiated decrease amounts to major rate classes through a credit to
      individual customers bills based on projections of base rate revenues for
      each individual rate class.

2.    The negotiated decrease amounts (merger and rate reduction) by major rate
      class will be allocated to the individual rate classes within each major
      rate class based upon projected base rate revenues. The resulting base
      rate revenue credits will be an equal percentage of projected base rate
      revenues for individual rate classes within a major rate class.

3.    Projected base rate revenues will include all retail base rate revenues
      with the exception of revenues associated with miscellaneous services,
      fees and facility rentals. Projected base rate revenues for each
      individual rate class will be based upon consecutive twelve month periods,
      not necessarily a calendar year.

4.    The individual rate class refund factors will be calculated by dividing
      the base rate revenue credits assigned to that rate class, determined in
      #2 above, by the corresponding annual projected base revenue for that rate
      class.

5.    The year one refund factors will be filed with the PUCT 30 days prior to
      the anticipated effective date of the merger. These factors will be
      implemented as of the first day of the first billing month after the
      effective date of the merger and will be applicable for the initial 12
      month period. The approval of this settlement by the PUCT will establish
      the refund methodology and all other compliance filings for annual refund
      factors will be administrative in nature.

6.    No less than 60 days prior to the expiration of the current refund
      factors, each Texas operating Company will make compliance filings to
      implement new refund factors for the upcoming 12 month period. These
      factors will be based on the refund amounts for the upcoming year plus any
      true-up amounts from the prior 12 month period.

7.    Due to the timing of these compliance filings, the exact amount of the
      current 12 month's over/under refund balance (true-up) will not be
      known at the time the next 12 month's refund factors are calculated.
      Estimates will need to be made for any periods (possibly two or three
      months) for which actual data is not available for the purposes of
      determining the amount of over/under refund balance to be included in
      the design of the net 12 month's refund factors.  The annual true-up of
      the refund amount, plus interest calculated in conformance with the
      provisions of the PUCT's fuel rule governing reconciliation proceedings
      (PUCT Substantive Rule 23.23(b)), will continue until such
<PAGE>   58
      time as the refund factor is no longer applicable. At such time that the
      refund factors are no longer applicable, each Texas operating Company will
      true-up the over/under refund balance for any prior outstanding months
      which were estimated.

8.    For purposes of the calculation of over/under refund balances each Texas
      operating Company will keep the balances of the refunds by individual rate
      class and any over/under balances will be included in the calculation of
      the next 12 month's refund factor for that individual rate class.

9.    In the event of industry restructuring legislation, the base rate revenue
      credits will be maintained by individual rate class, to the extent
      possible, although it is impossible to formulate a specific plan at this
      time. If and when restructuring legislation is enacted, the Applicants
      will submit a plan for PUCT approval to allocate the credits set forth in
      Attachments A and H consistent with Sections 3.C, 3.F(8) and Attachment H,
      Section 6.

                  MERGER OF CENTRAL AND SOUTH WEST CORPORATION

                    AND AMERICAN ELECTRIC POWER COMPANY, INC.

                                       I.

      Houston Lighting & Power Company; City Public Service Board of San
Antonio; Central Power and Light Company (CPL): City of Austin, Texas; and STP
Nuclear Operating Company are holders of Facility Operating Licenses Nos. NPF-76
and NPF-80, issued on March 22, 1988, and March 28, 1989, respectively. Facility
Operating Licenses Nos. NPF-76 and NPF-80 authorize the holders to possess the
South Texas Project, Units 1 and 2 (STP), and authorize STP Nuclear Operating
Company to use and operate STP in accordance with the procedures and limitations
set forth in the operating licenses. The Nuclear Regulatory Commission (NRC)
issued Licenses Nos. NPF-76 and NPF-80 on March 22, 1988, and March 28, 1989,
respectively, pursuant to Part 50 of Title 10 of the Code of Federal Regulations
(10 CFR Part 50). The facility is located in Matagorda County, Texas.

                                       II.

      Under cover of a letter dated June 19, 1998, CPL submitted an application
dated June 16, 1998, for consent under 10 CFR 50.80 to allow the indirect
transfer of CPL's interest in STP that would occur in connection with a proposed
merger of Central and South West Corporation (CSW, the parent holding company of
CPL) and American Electric Power, Inc. (AEP). Under the proposed merger, CSW
would become a wholly-owned subsidiary of AEP, with CPL remaining a wholly-owned
subsidiary of CSW. Houston Lighting & Power Company; City Public Service Board
of San Antonio; City of Austin, Texas; and
<PAGE>   2
STP Nuclear Operating Company are not involved in the merger. The application
was supplemented by a letter dated June 23, 1998, and enclosures thereto.

      CPL and the other current licensees would continue to hold the licenses,
and no direct transfer of the licenses would result from the merger. On August
5, 1998, a Notice of Consideration of Approval of Application Regarding Proposed
Merger was published in the Federal Register (63 FR 41876). An Environmental
Assessment and Finding of No Significant Impact was published in the Federal
Register on September 28, 1998 (63 FR 51629).

      Under 10 CFR 50.80, no license shall be transferred, directly or
indirectly, through transfer of control of the license, unless the Commission
gives its consent in writing. Upon review of the information contained in the
application dated June 16, 1998, and enclosures to the letter dated June 23,
1998, the NRC staff has determined that the proposed merger will not affect the
qualifications of CPL as holder of Facility Operating Licenses Nos. NPF-76 and
NPF-80, and that the transfer of control of the licenses, to the extent effected
by the proposed merger, is otherwise consistent with applicable provisions of
law, regulations, and orders issued by the Commission, subject to the conditions
set forth herein. These findings are supported by a safety evaluation dated
November 5, 1998.

                                      III.

Accordingly, pursuant to Sections 161b, 161i, 161o, and 184 of the Atomic Energy
Act of 1954, as amended; 42 U.S.C. Sections 2201(b), 2201(i), 2201(o), and
2234; and 10 CFR 50.80, IT IS HEREBY ORDERED that the Commission approves the
application regarding the merger agreement between CSW and AEP subject to the
following: (1) CPL shall provide the Director of the Office of Nuclear Reactor
Regulation with a copy of any application, at the time it is filed, to transfer
(excluding grants of security interests or liens) from CPL to its proposed
parents, or to any other affiliated company, facilities for the production,
transmission, or distribution of electric energy having a depreciated book value
exceeding 10 percent of CPL's consolidated net utility plant, as recorded on its
books of account, and (2) should the merger not be completed by December 31,
1999, this Order shall become null and void, unless upon application and for
good cause shown this date is extended.

      This Order is effective upon issuance.

                                       IV.

      By December 14, 1998, any person adversely affected by this Order may file
a request for a hearing with respect to issuance of the Order. Any person
requesting a hearing shall set forth with particularity how such person's
interest is adversely affected by this Order and shall address the criteria set
forth in 10 CFR 2.714(d).

      If a hearing is to be held, the Commission will issue an order designating
the time and place of such hearing.

      The issue to be considered at any such hearing shall be whether this Order
should be sustained.

      Any request for a hearing must be filed with the Secretary of the
Commission, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001,

                       SOUTH TEXAS PROJECT, UNITS 1 AND 2

1.0   INTRODUCTION

Pursuant to 10 CFR 50.80, Central Power and Light Company (CPL) submitted an
application dated June 16, 1998, under cover of a letter dated June 19, 1998,
and additional supporting material under cover of a letter dated June 23, 1998,
describing the proposed merger of Central and South West Corporation (CSW), the
parent holding company of CPL) and American Electric Power Company, Inc. (AEP).
The application requests the consent of the Nuclear Regulatory Commission (NRC)
to allow the indirect transfer of CPL's interest in STP that will occur under
the proposed merger of CSW and AEP.

CPL, as a wholly-owned subsidiary of CSW, owns a 25.2 percent interest in South
Texas Project, Units 1 and 2 (STP). Upon completion of the merger, CSW will
become a wholly-owned subsidiary of AEP, with CPL remaining a wholly-owned
subsidiary of CSW.

The merger will result in an indirect transfer of CPL's interest in the licenses
for STP to AEP, and approval for this indirect transfer is being sought from the
NRC pursuant to 10 CFR 50.80. Houston Lighting & Power Company, City Public
Service Board of San Antonio, and City of Austin, Texas, are the other owners of
STP, and the proposed merger does not involve any of them. The STP Nuclear
Operating Company (STPNOC) is a holder of the STP licenses and is the licensed
operator of STP, but STPNOC is not impacted by the merger. STPNOC holds no
ownership interest in either unit.

Pursuant to 10 CFR 50.80, the NRC may approve the transfer of the control of a
license, after notice to interested persons. Such action is contingent upon the
NRC's determination that the holder of the license following the transfer of
control is qualified to hold the license and the transfer is otherwise
consistent with applicable provisions of law, regulations, and orders of the
Commission.

In the application for approval dated June 16, 1998, the applicant states on
page 7:

      The purpose of the merger is to achieve benefits for AEP's and CSW's
      shareholders, customers and communities that would not be achievable if
      they were to remain separate companies. The potential net non-fuel cost
      savings related to the merger are approximately $2 billion over the first
      ten years following the merger. The savings will come from the elimination
      of duplicative activities, improved operating efficiencies, lower capital
      costs, and the combination of the companies' work forces. In addition, it
      is anticipated that there will be reduced fuel costs.

2.0   FINANCIAL QUALIFICATIONS

According to CPL's application, following the proposed merger, CPL will continue
to own its 25.2 percent interest in both Units 1 and 2 and will remain an
electric utility as defined in 10 CFR 50.2, engaged in the generation,
transmission, and distribution of electric energy through rates authorized by
the Public Utility
<PAGE>   5
Commission of Texas for retail purposes and by the Federal Energy Regulatory
Commission for wholesale transactions. As an electric utility, CPL is exempt
from further financial qualifications review, pursuant to 10 CFR 50.33(f).

However, in view of the NRC's concern that restructuring can lead to a
diminution of assets necessary for the safe operation and decommissioning of a
licensee's nuclear power plant, the NRC's practice has been to condition license
transfer approvals upon a requirement that the licensee not transfer significant
assets from the licensee to an affiliate without first notifying the NRC. This
requirement assists the NRC in assuring that a licensee will continue to
maintain adequate resources to contribute to the safe operation and
decommissioning of its facility. With regard to this requirement, CPL has agreed
on page 4 of its June 16, 1998, application:

      To provide the Director of the Office of Nuclear Reactor Regulation a copy
      of any application, at the time it is filed, to transfer (excluding grants
      of security interests or liens) from CPL to its proposed parents, or to
      any other affiliated company, facilities for the production, transmission
      or distribution of electric energy having a depreciated book value
      exceeding ten percent of CPL's consolidated net utility plant, as recorded
      on its books of account.

With the foregoing a condition of the Order approving the application regarding
the proposed merger, and abased on the above information, the staff finds that
CPL will remain financially qualified to hold the STP licenses following the
proposed merger.

3.0   TECHNICAL QUALIFICATIONS

STP Nuclear Operating Company, the only licensee of STP authorized to operate
and maintain the facility, is not involved in the proposed merger. CPL has
stated in its application that the proposed merger involves no change to either
the management organization or technical personnel of STP Nuclear Operating
Company. Accordingly, the proposed merger does not raise any problematic
technical qualifications issues.

4.0   ANTITRUST REVIEW

Section 105 of the Atomic Energy Act of 1954, as amended (the Act), requires the
NRC to conduct an antitrust review in connection with an application for a
license to construct or operate a facility under Section 103. Although AEP may
become the holding company of CSW, which in turn is the holding company of CPL
(a licensee for STP), i.e., may indirectly acquire control of the licenses, AEP
will not be performing activities for which a license is needed. Since approval
of the application would not involve issuance of a license and since CPL as the
existing licensee will remain the licensee, the procedures under Section 105
regarding antitrust reviews do not apply, including the making of any
"significant changes" determination.

5.0   FOREIGN OWNERSHIP, CONTROL, OR DOMINATION

CPL indicated in its application that it is now, and will be after the merger, a
corporation organized and existing under the laws of the State of Texas. All of
its directors and principal officers are citizens of the United States. The
application also indicated that after the merger is implemented, CPL will be an
indirect wholly-owned subsidiary of AEP. Subsequent to the merger, the Board of
Directors of AEP will be composed of 15 members, to include all then current
board members of AEP, the Chairman of CSW, and four additional outside directors
of CSW to be nominated by AEP. The current directors of AEP and the Chairman and
outside directors of CSW are U.S. citizens according the application. Nothing in
the application indicates that there will be any known changes in the
memberships of these boards occurring prior to the proposed merger. Counsel for
CPL confirmed on October 29, 1998, during a telephone conversation with Steven
R. Hom of the Office of the General Counsel, that there are no board elections
scheduled to occur prior to the merger, there is no present plan to change any
current board member prior to the


                                       2
<PAGE>   6
merger, and it is intended that all AEP board members following the merger will
be U.S. citizens. The application declares that following the proposed merger,
CPL will not be owned, controlled or dominated by an alien, foreign corporation,
or foreign government. The staff does not know or have reason to believe
otherwise.

6.0   CONCLUSIONS

In view of the foregoing, the staff concludes that the proposed merger of CSW
into AEP as a wholly-owned subsidiary of AEP will not adversely affect the
financial qualifications of CPL with respect to the operation and
decommissioning of STP. Also, there do not appear to be any problematic
antitrust or foreign ownership considerations related to the STP licenses that
would result from the proposed merger. Thus, the proposed merger will not affect
the qualifications of CPL as a holder of the licenses, and the transfer of
control of the licenses, to the extent effected by the proposed merger, is
otherwise consistent with applicable provisions of law, regulations, and orders
issued by the Commission pursuant thereto. Accordingly, the NRC should approve
the application regarding the proposed merger, subject to the condition
discussed above concerning significant asset transfers.

                                    O R D E R

         On April 15, 1999, Kentucky Power Company d/b/a American Electric Power
("Kentucky Power"), American Electric Power Company, Inc. ("AEP"), and Central
and South West Corporation ("CSW") (collectively, the "Joint Applicants")
applied to the Commission for an Order: (1) declaring that the merger of CSW and
AEP, with AEP being the surviving entity, may be consummated without Commission
approval or, alternatively, approving pursuant to KRS 278.020(4) and 278.020(5),
the proposed regulatory plan and authorizing other steps necessary to implement
the regulatory plan; (2) approving a tariff providing a net merger savings
credit for Kentucky Power customers; and (3) making certain findings concerning
the deferral of certain merger-related expenses in conformity with SFAS 71.

         On April 20, 1999, the Commission established a procedural schedule
that provided for discovery, an evidentiary hearing, and an opportunity for
parties to file briefs. The Commission granted full intervention to the
following entities: Attorney General's Office of Rate Intervention ("AG",
Kentucky Industrial Utility Customers ("KIUC"), and Kentucky Electric Steel
Corporation (collectively, the "Intervenors"). Following several conferences
held under the Commission's auspices, the parties resolved all disputed issues
and executed a "Stipulation and Settlement Agreement" which they filed with the
Commission on May 24, 1999. The
<PAGE>   2
Commission held a public hearing in this matter on May 28, 1999, at the
Commission's offices in Frankfort, Kentucky.

                           OVERVIEW OF THE TRANSACTION

         Kentucky Power. a Kentucky corporation, owns and operates facilities
engaged in the generation, transmission, distribution and sale of electricity.
It serves approximately 170,000 customers in the eastern Kentucky counties of
Boyd, Breathitt, Carter, Clay, Elliott, Floyd, Greenup, Johnson, Knott,
Lawrence, Leslie, Letcher, Lewis, Magoffin, Martin, Morgan, Owsley, Perry, Pike,
and Rowan. It also supplies electricity to public utilities and municipalities
in Kentucky for resale. Kentucky Power is a utility subject to Commission
jurisdiction. KRS 278.010(3)(a).

          AEP, a New York corporation, is a holding company registered under the
Public Utility Holding Company Act of 1935.(1) It owns, directly or indirectly,
all of the outstanding common stock of seven domestic electric utility operating
subsidiaries: Appalachian Power Company, Columbus Southern Power company,
Indiana Michigan Power Company, Kentucky Power, Kingsport Power Company, Ohio
Power Company and Wheeling Power Company. Its subsidiaries provide electricity
to over 3 million customers in Kentucky, Indiana, Michigan, Ohio, Tennessee,
Virginia, and West Virginia.

         CSW, a Delaware corporation, is a holding company registered under the
Public Utility Holding Company Act of 1935. It owns all of the outstanding
common stock of four domestic electric utility operating subsidiaries: Central
Power and Light Company, Public Service Company of Oklahoma, Southwestern
Electric Power Company and West Texas Utilities

Company. These subsidiaries provide electricity to over 1.7 million customers in
areas of Texas, Oklahoma, Arkansas and Louisiana.

         On December 21, 1997, AEP and CSW, with the approval of their
respective Boards of Directors, executed a merger agreement. Under the terms of
this agreement, shareholders of CSW will receive .6 of a share of AEP stock for
each share of CSW common stock, resulting in CSW shareholders acquiring 40
percent of AEP's common stock. The four CSW domestic utility subsidiaries will
become AEP subsidiaries. AEP's Board of Directors will be expanded from 12 to 15
members, with two AEP board members retiring. Five directors, formerly on the
CSW Board of Directors, will be selected to serve upon AEP's Board.

         The Joint Applicants estimate that the proposed merger will produce
approximately $2.4 billion in non-fuel savings over a 10-year period. After
considering the cost to achieve these savings and pre-merger initiatives, the
proposed merger is estimated to produce net merger savings of $1.965 billion. Of
this amount, Kentucky Power will be allocated $73.8 million. These savings are
expected to result from the elimination of duplicative functions and positions
and greater economies of scale the merger is expected to produce.

          Because of the geographical area served by the Joint Applicants and
their affiliates and the nature of their operations, the utility regulatory
commissions of six states,(2) the Federal Energy Regulatory Commission ("FERC"),
the Securities and Exchange Commission ("SEC"), the Federal Trade Commission
("FTC"), the United States Department of Justice ("DOJ"), and the Nuclear
Regulatory Commission ("NRC") must approve the proposed merger. As of

May 28, 1999, the NRC, Arkansas Public Service Commission, Indiana Utility
Regulatory Commission, and Oklahoma Corporation Commission have granted their
approval.

                      STIPULATION AND SETTLEMENT AGREEMENT

     On May 24, 1999, the parties filed a "Stipulation and Settlement Agreement"
("Settlement Agreement") with the Commission. The most significant features of
the Settlement Agreement are described below.

     Merger Savings. The Settlement Agreement provides for the implementation of
a Net Merger Savings Credit ("Merger Credit") tariff that will reduce customers'
bills beginning in the first full billing month 30 days after the consummation
of the merger. The Merger Credit will appear on each customer's monthly bill and
will be based upon kWh consumption. The Merger Credit reflects non-fuel related
merger savings and the associated merger costs based on estimated values
included in AEP's merger filing with the FERC. Although the amounts are only
estimates, the Joint Applicants have committed to guarantee their estimate of
not merger savings. Associated merger costs have been classified by AEP as
either "Cost to Achieve" or "Change in Control Payments."(3)

         The Merger Credit will be in effect for an initial eight-year period,
with all associated merger costs amortized over the same eight years. The Cost
to Achieve the merger will be shared by both customers and shareholders of AEP,
while the Change in Control Payments will be borne solely by AEP shareholders.
At the completion of the initial eight years, customers will


- ----------------------
(3) The Change in Control Payments relate to a special incentive plan adopted by
CSW for 16 key employees in October 1996. See Joint Applicants' Response to
Commission Staff's Information Request (requested at the informal conference of
April 22, 1999), Item 4 at 61.

                                       4
<PAGE>   5
have received 55 percent, or $28.365 million, of the total net merger savings
for the period.(4) The Merger Credit will continue beyond the initial eight-year
period, reflecting the gross merger savings estimated for the eighth year, and
will be allocated between customers and shareholders in the same manner as was
utilized during the initial eight-year period. This annual amount of customer
savings will be $5.243 million and will continue until Kentucky Power's next
base rate case which will allocate total gross merger savings to customers.
Should Kentucky Power file a base rate case during the initial eight-year
period, the Merger Credit will remain in effect. Any legislatively mandated
rates that are part of any legislation enacted to deregulate the electric
industry in Kentucky will not diminish or offset, but will be in addition to,
the bill reductions established in the Settlement Agreement.

         Rate Moratorium. The Settlement Agreement provides that Kentucky Power
will not request a general increase in its existing base rates and charges that
will be effective prior to January 1, 2003, or three years from the effective
date of the merger, whichever is later. Kentucky Power's fuel adjustment clause,
environmental surcharge, demand side management adjustment clause and system
sales tracker are not included in this rate moratorium. Kentucky Power,
moreover, may seek a general rate adjustment during the moratorium period if,
after a public evidentiary hearing, the Commission determines that events
constituting a force majeure as defined in the Settlement Agreement have
occurred. The Intervenors have agreed not to Seek a reduction in base rates
during the rate moratorium period. The Settlement Agreement does not preclude
the Commission from initiating proceedings to investigate Kentucky Power's rates

(4) See Settlement Agreement, Attachment A. The annual Merger Credit amount
ranges from $1.464 million to $4.626 million during the initial eight-year
period.

                                       5

         Fuel Savings. The Settlement Agreement provides that all savings of
fuel and purchase power expenses that result from the proposed merger will flow
directly to Kentucky Power's retail customers through its existing fuel
adjustment clause mechanism. AEP further agrees to hold Kentucky Power's native
load customers harmless from higher replacement power costs of foregone revenues
caused by current AEP operating companies supplying power to the service area of
the CSW operating companies.

         Environmental Surcharge Litigation. The Settlement Agreement seeks to
resolve all outstanding matters involving Kentucky Power's environmental
surcharge mechanism. It requires the dismissal of all appeals,(5) including the
Commission's, now before the Kentucky Court of Appeals involving the
Commission's Orders in Case No. 96-489.(6) All parties will dismiss their
appeals without prejudice. The Settlement Agreement further provides that
Kentucky Power may, beginning January 1, 2000, recover through its environmental
surcharge mechanism the costs associated with the low NOx burners for Big Sandy
Generating Units No. 1 and No. 2. Kentucky Power will forego any recovery of
costs eligible for recovery prior to January 1, 2000.(7) The Settlement
Agreement also provides that the Commission's most recent review(8) of Kentucky
Power's environmental surcharge be closed without further adjustment.

         Affiliated Standards. The Settlement Agreement provides for affiliate
standards and guidelines that will apply to transactions between AEP operating
companies and their affiliates. These standards will take effect upon the
consummation of the merger and remain in effect "until new affiliate standards
imposed by either the Commission or by the General Assembly."(9)

         Quality of Service. The Settlement Agreement requires Kentucky Power
and AEP to maintain service quality and reliability at existing levels. Kentucky
Power and AEP agree to provide annually service reliability reports addressing
the duration and frequency of customer disruptions and annual Call Center
performance measures for those centers that handle Kentucky customer calls. They
also commit to compile outage data detailing each circuit's reliability
performance to identify and resolve reliability problems.

         Most Favored Nations Provisions. The Joint Applicants agree that if, in
connection with the proposed merger, any state or federal regulatory commission
imposes conditions on AEP that would benefit ratepayers in one jurisdiction,
equivalent net benefits and conditions will be extended to Kentucky retail
customers.

                               COMMISSION FINDINGS

         Having thoroughly reviewed the Settlement Agreement, the Commission
finds that the Settlement Agreement represents a reasonable resolution to the
issues surrounding the proposed merger and should be approved. The Settlement
Agreement allows for a fair and equitable

distribution of the merger benefits between ratepayers and shareholders and
protects Kentucky Power ratepayers from many of the potential risks posed by the
merger.

         The Commission notes that the Settlement Agreement imposes new
reporting requirements on Kentucky Power in the areas of service quality and
reliability. While we recognize the difficulties presented by the terrain and
topography in portions of Kentucky Power's service territory, the Commission
reminds Kentucky Power that its top priority must be service quality and
reliability. In the event that Kentucky Power's quality of service experiences a
decline, the Commission is prepared to require additional measures be taken.

         The Commission also notes that the Settlement Agreement will end the
lengthy and extensive litigation surrounding Kentucky Power's environmental
surcharge mechanism. By this Order, we approve in principle those provisions and
authorize our legal counsel to take all actions necessary to implement the
Settlement Agreement's provisions and to dismiss all outstanding appeals pending
before the Kentucky Court of Appeals. Because the issues dealing with Kentucky
Power's environmental surcharge mechanism are addressed in other Commission
proceedings that have not been consolidated with this proceeding, however. the
Commission must implement certain of the provisions related to that mechanism
through Orders in those proceedings. The Commission will issue those Orders as
soon as possible.(10)



- ---------------------

(10) Within the next few days, the Commission will issue an Order in Case No.
98-624 to close Kentucky Power's current environmental surcharge proceedings.
Implementing the provisions related to the recovery of the costs associated with
the low NOx burners for Big Sandy Generating Units No. 1 and No. 2 will require
the issuance of an Order in Case No. 96-489. That action will occur upon
dismissal of all outstanding appeals.

                             REPORTING REQUIREMENTS

         In previous cases,(11) the Commission has determined that to
effectively monitor the activities of the jurisdictional utility, its parent
company and related subsidiaries, and to protect ratepayers, certain additional
reports should be furnished by the jurisdictional utility to the Commission on
an annual, periodic, or other basis as appropriate. The Commission finds that
similar requirements are appropriate in this case as well. (12)


Periodic Reports

         The annual financial statements of AEP should be furnished, including
consolidating adjustments of AEP and its subsidiaries with a brief explanation
of each adjustment and all periodic reports filed with the SEC. (13) All
subsidiaries should prepare and have available monthly and annual financial
information required to compile financial statements and to comply with other
reporting requirements. The financial statements for any non-consolidated
subsidiaries of AEP should be furnished to the Commission.

         AEP should also furnish the following reports on an annual basis:

         1. A general description of the nature of intercompany transactions
with specific identification of major transactions, and a description of the
basis upon which cost allocations


- -------------------
(11) See, e.g., Case No. 10296, The Application of Kentucky Utilities Company to
Enter Into an Agreement and Plan of Exchange and to Carry Out Certain
Transactions in Connection Therewith (Oct. 6, 1988); Case No. 89-374,
Application of Louisville Gas and Electric Company for an Order Approving an
Agreement and Plan of Exchange and to Carry Out Certain Transactions in
Connection Therewith (May 25, 1990); Case No. 94-104, Application of the
Cincinnati Gas & Electric Company and CINergy Corp. for Approval of the
Acquisition of Control of The Union Light, Heat & Power Company by CINergy Corp.
(May 13, 1994); Case No. 97-300, Joint Application of Louisville Gas and
Electric Company and Kentucky Utilities Company for Approval of Merger (Sept.
12, 1997).

(12) The imposition of these requirements is consistent with KRS 278.020(5), KRS
278.230 and Paragraph 8 of the Stipulation and Settlement Agreement.

(13) The requested SEC reports include, but are not limited to, the U5S and
U-13-60 reports.


                                       9
<PAGE>   10
and transfer pricing have been established. This report should discuss the use
of the cost or market standard for the sale or transfer of assets, the
allocation factors used, and the procedures used to determine these factors if
they are different from the procedures used in prior years.

         2. A report that identifies professional personnel transferred from
Kentucky Power to AEP or any of the non-utility subsidiaries and describes the
duties performed by each employee while employed by Kentucky Power and to be
performed subsequent to transfer.

         AEP should file on a quarterly basis, a report detailing Kentucky
Power's proportionate share of AEP's total operating, revenues, operating and
maintenance expenses, and number of employees.


Special Reports

         Other special reports should be furnished to the Commission as
necessary. In anticipation that transfers of utility assets and investments by
AEP will occur in the future, AEP should file any contracts or other agreements
concerning the transfer of such assets or the pricing of intercompany
transactions with the Commission at the time the transfer occurs.

         AEP should also file the following information:

         1. A quarterly report of the number of employees of AEP and each
subsidiary on the basis of payroll assignment.

         2. An annual report containing the years of service at Kentucky Power
and the salaries of professional employees transferred from Kentucky Power to
AEP or its subsidiaries filed in conjunction with the annual transfer of
employees report.

         3. An annual report of cost allocation factors in use, supplemented
upon significant change.

         4. Summaries of any cost allocation studies when conducted and the
basis for the methods used to determine the cost allocation in effect.



                                       10
<PAGE>   11
         5. An annual report of the methods used to update or revise the cost
allocation factors in use, supplemented upon significant change.

         6. Current Articles of Incorporation and bylaws of affiliated companies
in businesses related to the electric industry or that would be doing business
with AEP.

         7. Current Articles of Incorporation of affiliated companies involved
in non-related business.

         After consummation of the merger, AEP will remain a registered holding
company under the Public Utility Holding Company Act of 1935 and under the
oversight of several regulatory bodies. Where the same information sought in
these reports has been filed with the SEC, FERC, or another state regulatory
commission, AEP may provide copies of that filing rather than prepare separate
reports. Further, AEP may request the Commission to review these reporting
requirements after the merger is completed to determine if the documentation
being provided is either excessive or redundant.

         The Commission recognizes that the proposed merger has not yet received
all necessary regulatory approvals. Consequently, the form or substance of the
anticipated benefits of the merger might ultimately vary from those reviewed in
this case. To the extent that the merger is subject to conditions or changes not
reviewed in this case, the Joint Applicants should amend their filing to allow
the Commission and all parties an opportunity to review the revisions to ensure
that Kentucky Power and its customers are not adversely affected and that any
additional benefits flow through the favored nations clause.

                              MOTION FOR REHEARING

         The Kentucky Association of Plumbing-Heating-Cooling Contractors, Inc.
and Kentucky Propane Gas Association (collectively "Contractors") have moved
for reconsideration of the


                                       11
<PAGE>   12
Commission's Order of May 20, 1999 in which we denied their application for full
intervention. In support of their motion, the Contractors state that they have
an interest in this proceeding as the Joint Applicants have not expressly
precluded the possibility of competing with their members or to refrain such
competition pending completion of Administrative Case No. 369.(14)

         Having considered the motion, the Commission does not find good cause
to modify its May 20, 1999 Order. While the Commission acknowledges the
Contractors' concerns regarding utility affiliate transactions, these concerns
are more appropriately addressed in Administrative Case No. 369, which was
initiated specifically to review these issues as they relate to all regulated
utilities. Moreover, Commission approval of the Settlement Agreement neither
binds nor limits our ability to deal with the issue of affiliated transactions.
The Settlement Agreement contains no provision limiting the scope of our
discretion in this area. It specifically provides that its affiliate standards
"apply from the date of closing of the merger until new affiliate standards
imposed by state legislation or State Commission action become effective."
Settlement Agreement at 6.

                                     SUMMARY

         After consideration of the evidence and being otherwise sufficiently
advised, the Commission finds that:

         1. The proposed merger of AEP and CSW will result in an indirect change
in control of Kentucky Power and therefore requires prior Commission approval.

IN THE MATTER OF:

JOINT APPLICATION OF KENTUCKY POWER COMPANY  )
AMERICAN ELECTRIC POWER COMPANY, INC.        )
AND CENTRAL AND SOUTH WEST CORPORATION       )     CASE NO.  99-149
REGARDING A PROPOSED MERGER                  )



                      STIPULATION AND SETTLEMENT AGREEMENT

On February 17, 1999 the Staff of the Public Service Commission of Kentucky
("Commission") issued a letter stating staff's belief that the Commission has
jurisdiction under KRS 278.020(5) to review the proposed merger of Central and
South West Corporation ("CSW") into American Electric Power Company, Inc.
("AEP") and requested that Kentucky Power Company ("Kentucky Power", "KPCO" or
the "Company") advise in writing by March 8, 1999 of the date AEP would file an
application for Commission approval of "the indirect change in control of
Kentucky Power Company." On March 5, 1999 the Company issued a letter notifying
the Commission that it would file the requested application by April 15, 1999.
The letter also indicated that the Company expected to provide the Staff and the
Commission with sufficient information to enable the Commission to approve its
application within the sixty (60) day period prescribed by the statute. The
letter further preserved the Company's legal arguments regarding the application
of KRS 278.020 (5) to this merger.

On April 15, 1999 the Company, AEP and CSW filed a Joint Application with
supporting testimony and workpapers. The proceeding was designated P.S.C. Case
No. 99-149. On April 22, 1999 the Commission issued a letter indicating that the
Commission staff had reviewed the Company's application and found that it met
the minimum filing requirements.

On May 4, 1999 the Attorney General, Office of the Rate Intervention ("Attorney
General"), and Kentucky Electric Steel, Inc. ("KESI") were granted full
intervention in Case No. 99-149. On May 11, 1999 Kentucky Industrial Utility
Customers Inc. ("KIUC"), was also granted full intervention in Case No. 99-149.
These parties will be referred to herein collectively as the "Intervenors".

On April 22, 1999 a Technical Conference was held at the Commission's offices.
On May 4, May 11, May 17, and May 20, 1999 settlement conferences were held at
the Commission's offices. Present were the Staff and counsel for the
Intervenors, as well as Company representatives.
<PAGE>   18
Solely for the purposes of compromise and settlement of the issues in this
proceeding, Central and South West Corporation, American Electric Power Company,
Inc., Kentucky Power Company, which does business in Kentucky as American
Electric Power, the Attorney General, Kentucky Industrial Utility Customers,
Inc. and Kentucky Electric Steel, Inc. (collectively referred to as the
"Parties") have met and reached a settlement agreement ("Agreement") which they
hereby submit and recommend for approval to the Commission. If the Commission
does not approve the settlement agreement in its entirety and incorporate it in
the Final Order, the proposed Agreement shall be null and void and deemed
withdrawn, unless such change is agreed to by the Parties.

                              SETTLEMENT AGREEMENT

WHEREAS AEP and CSW have filed various applications before federal and state
agencies seeking approvals necessary to consummate a proposed merger of the two
companies; and

WHEREAS the Parties have met and explored various issues related to the proposed
merger and their agreements and differences regarding the effects of the
proposed merger on competition between electricity providers and on the terms
and conditions under which retail electric utility service is provided; and

WHEREAS the Parties recognize the costs and uncertainty of litigation and the
desirability of consensual voluntary resolution of their differences and the
legitimate interests and good faith of each of the parties in achieving the
objectives each desires to achieve; and

WHEREAS, the Parties agree as follows:

That AEP, KPCO and the Intervenors will recommend to the Commission that the
following Agreement be adopted by the Commission in an order or other
appropriate formal action that references this Agreement or incorporates all of
the provisions thereof. Where appropriate, the Commission action may address or
reserve other matters ancillary or incidental to the matters addressed in this
Agreement, for immediate or future disposition, in a manner not inconsistent
with the Agreement.

All appropriate terms are defined in the "Definitions" section of the Agreement.

The Parties:

1. Will not oppose the proposed merger pending before the Federal Energy
Regulatory Commission ("FERC").

2. Will not oppose AEP's filings previously made at the United States Securities
and Exchange Commission ("SEC") in connection with the proposed merger, together
with any non-material changes or supplements thereto.
<PAGE>   19
AEP, or Kentucky Power Company, conditional on merger consummation will:

1. REGULATORY PLAN. KPCO will implement a Net Merger Savings Credit tariff that
will reduce bills to customers by the annual amounts shown in Attachment A
beginning with the first full billing month available following thirty days from
the consummation of the merger. The annual bill reduction amounts shown in
Attachment A will be refunded to customers based upon kwh consumption. Each
individual year's bill reduction will apply for a twelve month period. A
Balancing Adjustment Factor (B.A.F.) per Kwh will be included for the second
through the twelfth month of the current distribution year which will reconcile
any over- or under-distribution of the net savings from prior years.

The merger savings and costs are based on estimated values included in AEP's
filing with the Federal Energy Regulatory Commission ("FERC") in Docket No.
EC98-40-000.

Absent a force majeure, KPCO will not file a petition, which, if approved, would
have the effect, either directly or indirectly, of authorizing a general
increase in basic rates and charges that would be effective prior to January 1,
2003 or three years from the effective date of the merger, whichever is later
(the "rate moratorium"), and the Intervenors agree not to seek a reduction in
base rates during the rate moratorium. During this period, the fuel adjustment
clause, the environmental surcharge, the demand side management adjustment and
the system sales tracker shall continue in force and shall not be subject to any
freeze. During the rate moratorium period, and not withstanding any force
majeure event, any discount, including but not limited to, operating reserve and
interruptible discounts contained in special contracts as currently approved by
the Commission, shall remain in force and shall not be changed for any customer
receiving the discount.

The Parties and the Commission will dismiss the appeals and cross-appeals in
Case Nos. 98 CA 00137, 98 CA 001344, 98 CA 001417, 98 CA 001455 and 98 CA
002476. The dismissal shall be without prejudice in any other action with
respect to the positions taken by the parties in dismissed litigation.

Effective January 1, 2000, KPCO shall begin collecting the environmental
surcharge, including the costs of the Low Nox burners for the Big Sandy
generating plant's Unit No. 1 and Unit No. 2, in accordance with the decisions
of the Franklin Circuit Court Opinion and Order dated April 30, 1998 and its
Amended Opinion and Order dated May 14, 1998 in Consolidated Case Nos.
97-CI-01138, 97-CI-01144 and 97-CI-00137 (except those portions of the decision
allowing retroactive recovery of the surcharge).

The parties further agree that there shall be no adjustment to the environmental
surcharge as a result of the six month review in P.S.C. Case No. 98-624.

Notwithstanding any base rate proceeding during the eight year period after the
consummation of the merger, the annual amounts shown in Attachment A will remain
in effect. After the eight year period and absent a base rate proceeding, the
Company will continue through the Net Merger Savings Credit to reduce bills to
customers by the annual amount shown on Attachment
<PAGE>   20
A which is the customers' portion of the net savings without the amortization of
the costs to achieve during the eighth year after the consummation of the
merger.

KPCO must implement the above rate reductions in the manner and amounts
described above notwithstanding any changes to the current regulatory structure
in Kentucky. In the event that retail electric deregulation legislation is
implemented in Kentucky or if there is any unbundling or restructuring, KPCO
shall continue to apply the regulatory plan's provisions to regulated rates of
its Kentucky retail jurisdictional customers.

Any legislatively mandated adjustments to base rates, of any kind, that are part
of any retail electric deregulation legislation implemented in Kentucky shall
not diminish or offset, but shall be in addition to, the bill reductions
established in this proceeding.

Subject to this agreement, AEP and KPCO will defer and amortize their Kentucky
retail jurisdictional estimated merger related costs-to-achieve over an 8-year
recovery period. Costs to achieve the merger are those costs incurred to
consummate the merger and combine the operations of AEP and CSW. These costs
include, but are not limited to, investment banking fees; consulting and legal
services incurred in connection with obtaining regulatory and shareholder
approvals; transition planning and development costs; employee separation costs
including severance costs, change-in-control payments and retraining costs; and
facilities consolidation costs. The Commission will issue accounting orders or
other orders necessary to authorize the deferral and amortization of merger
costs.

If the merger is not consummated, the Company commits and agrees not to seek to
recover termination fees, the "Out of Pocket" and "Topping Out" fees associated
with the merger as described in Sections 9.5 and 9.6 of the Agreement and Plan
of Merger By and Among American Electric Power Company, Inc., Augusta
Acquisition Corporation and Central and South West Corporation dated December
21, 1997 (Merger Agreement); and further commit and agree not to seek to recover
the fee that may be charged by Morgan Stanley.

In any proceeding to change base rates for KPCO to become effective after the
consummation of the merger, the following rate treatment will be reflected:

         A.       Estimated non-fuel merger savings, net of costs to achieve
                  will be included in cost of service as an allowable expense in
                  order to avoid duplication and to continue to provide
                  shareholders with their share of the net savings. The amount
                  to be included in the cost of service shall be based upon the
                  test year period. (See Attachment B).

         B.       Amortization of estimated costs to achieve will be included in
                  cost of service as an allowable expense. The amount to be
                  included in the cost of service shall be based upon the test
                  year period. (See Attachment B).

In any base rate proceeding after the eight year period, neither the merger
savings credit rider nor the expense adjustments described in A. and B. above
will be reflected in the test year.

2. FUEL MERGER SAVINGS. All savings of fuel and purchased power expenses
resulting from the merger shall benefit retail customers through existing fuel
clause recovery mechanisms applied by State Commissions. In circumstances when
one or more AEP operating companies in one AEP zone are supplying power to the
other AEP zone, and as a result, the supplying zone needs to purchase
replacement power to serve its native load, AEP shall hold harmless the native
load customers of the supplying zone from any price differential between the
replacement power and the system power supplied to the other zone. Similarly, if
one or more AEP operating companies in one AEP zone are supplying power to the
other AEP zone, and as a result, the supplying zone loses the opportunity to
sell power at a price higher than received from the zone being supplied, AEP
shall credit the supplying zone for the foregone revenues.

3. For purposes of this Settlement Agreement, force majeure shall mean
circumstances that cause any of the following to occur: a) the bond rating for
Kentucky Power Company to fall below an investment grade rating of Baa3
(Moody's) or BBB- (Standard & Poor's), or b) an increase in the federal and/or
state income taxes of KPCO, which increase is the result of changes in federal
or state income tax provisions, or c) an increase in KPCO's total electric
operating expenses, excluding fuel and purchased power, due to circumstances
beyond its control, and further excluding the costs of compliance with federal,
state or local environmental requirements which apply to coal combustion wastes
and by-products from facilities utilized for production of energy from coal.

For purposes of this force majeure provision, an increase is defined as an
increase in expense in an annualized amount greater than five percent (5%) of
AEP's Kentucky jurisdictional net revenues (i.e., operating revenues less fuel
and purchased power) for the preceding twelve months.

A force majeure may only exist under the terms of this Settlement Agreement if
the Commission finds in a rate application filed by the Company that the
circumstances allowed for under this Settlement Agreement are a force majeure,
as defined in this Agreement, after a public evidentiary hearing in which al the
Parties may participate.

4. STRANDED COSTS. AEP and its operating companies agree not to seek or recover
any stranded costs associated with the operating companies of one AEP zone from
the retail customers of the other AEP zone.

5. PROCEEDS OF FACILITY SALES. Any proceeds from the sale of facilities shall go
to the AEP operating company in whose rate base the facilities are included, for
further disposition in accordance with the rules and orders of the regulatory
authorities whose jurisdiction encompasses the ultimate disposition of such
proceeds.

6. SYSTEM INTEGRATION AGREEMENTS. To mitigate any perceived impacts of the
merger on AEP's ability to exercise market power. AEP proposed in its FERC
merger application a mitigation plan. To protect retail customers, AEP agrees to
hold harmless the retail customers from any mitigation plan included in any FERC
order approving the merger of AEP-CSW. To implement this Agreement in any
general retail electric rate proceeding commenced by the filing of a petition on
or after the date of this Agreement, in which an AEP operating
<PAGE>   22
company requests a change in its basic rates and charges, or in any other
proceeding where so ordered by the State Commission, AEP shall have the burden
therein to prove that such requested rate relief does not reflect
mitigation-related costs.

AEP commits to file any allocation of the cost of new, modified or upgraded
generation or transmission facilities whose costs will be subject to the System
Integration Agreement or the System Transmission Agreement with the FERC and to
notify each State Commission of any such filing at the time it is made.
Notification to each State Commission will include an estimate of the cost of
construction, an explanation of the reasons for constructing the facilities,
studies supporting the construction of the facilities, and a proposed allocation
of the facilities' costs. If AEP plans to purchase an in-service facility or
already constructed and soon-to-be-in-service facility, AEP will follow the
above described procedures and will include as part of the notification to the
State Commission an explanation of the circumstances causing the AEP operating
company to make the purchase in question.

7. REGULATORY AUTHORITY. AEP agrees not to seek to overturn, reverse, set aside,
change or enjoin, whether through appeal or the initiation or maintenance of any
action in any forum, a decision or order of a State Commission based on the
assertion that the authority of the Securities and Exchange Commission as
interpreted in Ohio Power Co. v. FERC, 954 F.2d 779 (D.C. Cir. 1992) cert.
denied, 498 U.S. 73 (1992) impairs the State Commission's ability to examine and
determine the reasonableness of non-power affiliate transaction costs to be
passed to retail customers. The parties agree that the Ohio Power waiver does
not include waiver of any arguments that AEP may have with respect to the
reasonableness of SEC approved cost allocations. AEP will provide each State
Commission with notice at least 30 days prior to any filings that propose new
allocation factors with the SEC. The notice need not be in the precise form of
the filing but shall include, to the extent information is available, a
description of the proposed factors and the reasons supporting such factors. AEP
and State Commission Staff will make a good faith attempt to resolve their
differences, if any, in advance of a filing being made at the SEC.

8. AFFILIATE STANDARDS. The following affiliate standards shall apply from the
date of closing of the merger until new affiliate standards imposed by state
legislation or State Commission action become effective.

         A.       The financial policies and guidelines for transactions between
                  an AEP operating company and its affiliates shall reflect the
                  following principles:

                  1.       An AEP operating company's retail customers shall not
                           subsidize the activities of the operating company's
                           non-utility affiliates or its utility affiliates.

                  2.       An AEP operating company's costs for jurisdictional
                           rate purposes shall reflect only those costs
                           attributable to its jurisdictional customers.

                  3.       These principles shall be applied to avoid costs
                           found to be just and reasonable for ratemaking
                           purposes by the affected State Commission being left
                           unallocated or stranded between various regulatory
                           jurisdictions,
<PAGE>   23
                           resulting in the failure of the opportunity for
                           timely recovery of such costs by the operating
                           company and/or its utility affiliates; provided,
                           however, that no more than one hundred percent of
                           such costs shall be allocated on an aggregate basis
                           to the various regulatory jurisdictions.

                  4.       An AEP operating company shall maintain and utilize
                           accounting systems and records that identify and
                           appropriately allocate costs between the operating
                           company and its affiliates, consistent with these
                           cross-subsidization principles and such financial
                           policies and guidelines.

         B.       Each State Commission shall have access to the employees,
                  officers, books and records of any affiliate of its
                  jurisdictional AEP operating company to the same extent and in
                  like manner that each such State Commission has over a public
                  utility operating within the state in which such State
                  Commission exercises its regulatory authority if the affiliate
                  had engaged in direct or indirect transactions with the
                  jurisdictional AEP operating company. If such employees,
                  officers, books and records can not be reasonably made
                  available to a State Commission, then upon request of a State
                  Commission, the AEP operating company shall, in accordance
                  with state reimbursement rules, reimburse the State Commission
                  for appropriate out-of-state travel expenses incurred in
                  accessing the employees, officers, books and records. Each AEP
                  operating company shall maintain, in accordance with generally
                  accepted accounting principles, books, records, and accounts
                  that are separate from the books, records, and accounts of its
                  affiliates, consistent with Part 101 - Uniform System of
                  Accounts Prescribed for Public Utilities and Licensees Subject
                  to the Provisions of the Federal Power Act. Any objections to
                  providing all books and records must be raised before the
                  State Commission and the burden of showing that the request is
                  unreasonable or unrelated to the proceeding is on the AEP
                  operating company. The confidentiality of competitively
                  sensitive information shall be maintained in accordance with
                  each State Commission's rules and regulations.

         C.       In accordance with generally accepted accounting principles
                  and consistent with state and federal guidelines, an AEP
                  operating company shall record all transactions with its
                  affiliates, whether direct or indirect. An AEP operating
                  company and its affiliates shall maintain sufficient records
                  to allow for an audit of the transactions involving the
                  operating company and its affiliates. Asset transfers from an
                  AEP operating company to a non-utility affiliate and asset
                  transfers from a non-utility affiliate to an AEP operating
                  company shall be at fully distributed costs in accordance with
                  current Securities and Exchange Commission (SEC) issued
                  requirements or other statutory requirements if the SEC has no
                  jurisdiction.

         D.       An AEP operating company shall not allow a non-utility
                  affiliate to obtain credit under any arrangement that would
                  permit a creditor, upon default, to have recourse to the
                  operating company's assets. The financial arrangements of an
                  AEP operating company's affiliates are subject to the
                  following restrictions unless otherwise approved by that
                  operating company's State Commission:
<PAGE>   24
                  1.       An indebtedness incurred by a non-utility affiliate
                           will be without recourse to the operating company.

                  2.       An AEP operating company shall not enter into any
                           agreements under terms of which the operating company
                           is obligated to commit funds in order to maintain the
                           financial viability of a non-utility affiliate.

                  3.       An AEP operating company shall not make any
                           investment in a non-utility affiliate under
                           circumstances in which the operating company would be
                           liable for the debts and/or liabilities of the
                           non-utility affiliate incurred as a result of acts or
                           omissions of a non-utility affiliate.

                  4.       An AEP operating company shall not issue any security
                           for the purpose of financing the acquisition,
                           ownership, or operation of a non-utility affiliate.

                  5.       An AEP operating company shall not assume any
                           obligation or liability as guarantor, endorser,
                           surety, or otherwise with respect to any security of
                           a non-utility affiliate.

                  6.       An AEP operating company shall not pledge, mortgage
                           or otherwise use as collateral any assets of the
                           operating company for the benefit of a non-utility
                           affiliate.

                  7.       AEP shall hold harmless the retail customers of an
                           AEP operating company from any adverse effects of
                           credit rating declines caused by the actions of
                           non-utility affiliates.

         Transactions between AEP operating companies and affiliates involving a
         money pool for the financing of short-term funding requirements are
         exempt from the requirements of this paragraph. Further, the provisions
         of this paragraph would not preclude AEP operating companies from
         issuing securities or assuming obligations related to their existing
         coal subsidiaries.

         E.       An untariffed, non-utility service provided by an AEP
                  operating company or affiliated service company to any
                  affiliate shall be itemized in a billing statement pursuant to
                  a written contract or written arrangement. The AEP operating
                  company and any affiliated service company shall maintain and
                  keep available for inspection by the State Commission copies
                  of each billing statement, contract and arrangement between
                  the AEP operating company or affiliated service company and
                  its affiliates that relates to the provision of such
                  untariffed non-utility services.

         F.       Any good or service provided by a non-utility affiliate to an
                  AEP operating company shall be by itemized billing statement
                  pursuant to a written contract or written arrangement. The
                  operating company and non-utility affiliate shall maintain and
                  keep available for inspection by the State Commission copies
                  of each billing statement, contract and arrangement between
                  the operating company
<PAGE>   25
                  and its non-utility affiliates that relates to the provision
                  of such goods and services in accordance with applicable State
                  Commission retention requirements.

         G.       Employees responsible for the day to day operations of the AEP
                  operating companies and those of affiliated exempt wholesale
                  generators or affiliated power marketers shall operate
                  independently of one another. AEP shall document all employee
                  movement between and among all affiliates. Such information
                  shall be made available to each State Commission and consumer
                  advocate upon request.

         H.       An AEP operating company may not own property in common with
                  an affiliated exempt wholesale generator or affiliated power
                  marketer.

         I.       No market information obtained in the conduct of utility
                  business may be shared with an affiliated exempt wholesale
                  generator or affiliated power marketer, except where such
                  information has been publicly disseminated or simultaneously
                  shared with an made available to all non-affiliated entities
                  who have requested such information. Customer specific
                  information shall not be made available to an affiliated
                  exempt wholesale generator or affiliated power marketer except
                  under the same terms as such information would be made
                  available to a non-affiliated company, and only with the
                  written consent of the customer specifying the information to
                  be released.

         J.       A non-utility affiliate may use an AEP operating company's
                  name or logo only if, in connection with such use, the
                  affiliate makes adequate disclosures to the effect that (i)
                  the two entities are separate; (ii) it is not necessary to
                  purchase the non-regulated product or service to obtain
                  service from the operating company; and (iii) the customer
                  will gain no advantage from the operating company by buying
                  from the affiliate.

         K.       An AEP operating company shall not condition or tie the
                  provision of any product, service, pricing benefit, or waiver
                  of associated terms or conditions, to the purchase of any good
                  or service from its affiliated exempt wholesale generator or
                  power marketer.

         L.       Except as provided in paragraph M, an affiliated exempt
                  wholesale generator or affiliated power marketer shall not
                  share office space, office equipment, computer systems or
                  information systems with an AEP operating company.

         M.       Computer systems and information systems may be shared between
                  an AEP operating company and non-utility affiliates only to
                  the extent necessary for the provision of corporate support
                  services; however, the operating company shall ensure that the
                  proper security access and other safeguards are in place to
                  ensure full compliance with these affiliate rules.

         N.       An AEP operating company may engage in transactions directly
                  related to the provision of corporate support services with
                  its affiliates in accordance with requirements relating to
                  service agreements. As a general principle, such provision of
                  corporate support services shall not allow or provide a means
                  for the
<PAGE>   26
                  transfer or confidential information from the operating
                  company to the affiliate, create the opportunity for
                  preferential treatment or unfair competitive advantage, create
                  opportunities for cross-subsidization of affiliates, or
                  otherwise provide any means to circumvent these affiliate
                  rules.

         O.       Except as provided in paragraph N, an AEP operating company
                  may only make a product or service available to an affiliated
                  exempt wholesale generator or an affiliated power marketer if
                  the product or service is equally available to all
                  non-affiliated exempt wholesale generators and power marketers
                  on the same terms, conditions and prices, and at the same
                  time. An AEP operating company shall process all requests for
                  a product or service from affiliated and non-affiliated exempt
                  wholesale generators and power marketers on a
                  non-discriminatory basis.

         P.       An AEP operating company which provides both regulated and
                  non-regulated services or products, or an affiliate which
                  provides services or products to an AEP operating company,
                  shall maintain documentation in the form of written
                  agreements, an organization chart of AEP (depicting all
                  affiliates and AEP operating companies), accounting bulletins,
                  procedure and work order manuals, or other related documents,
                  which describe how costs are allocated between regulated and
                  non-regulated services or products. Such documentation shall
                  be available, subject to requests for confidential treatment,
                  for review by State Commissions in accordance with Paragraph
                  B, above.

         Q.       AEP shall designate an employee who will act as a contact for
                  State Commissions and consumer advocates seeking data and
                  information regarding affiliate transactions and personnel
                  transfers. Such employee shall be responsible for providing
                  data and information requested by a State Commission for any
                  and all transactions between the jurisdictional operating
                  company and its affiliates, regardless of which affiliate(s),
                  subsidiary(ies) or associate(s) of an AEP operating company
                  from which the information is sought.

         R.       AEP shall designate an employee or agent within each signatory
                  state who will act as a contact for retail consumers regarding
                  service and reliability concerns and to allow a contact for
                  retail consumers for information, questions and assistance.
                  Such AEP representative shall be able to deal with billing,
                  maintenance and service reliability issues.

         S.       AEP shall provide each signatory state a current list of
                  employees or agents that are designated to work with each
                  State Commission and consumer advocate concerning state
                  regulatory matters, including, but not limited to, rate cases,
                  consumer complaints, billing and retail competition issues.

         T.       Thirty (30) days prior to filing any affiliate contract
                  (including service agreements) with the SEC or the FERC an AEP
                  operating company shall submit to each affected State
                  Commission a copy of the proposed filing.
<PAGE>   27
         U.       Any violation of the provisions of these affiliate standards
                  are subject to the enforcement powers and penalties at the
                  State Commissions.

         V.       AEP shall contract with an independent auditor who shall
                  conduct biennial audits for ten years after merger
                  consummation of affiliated transactions to determine
                  compliance with these affiliate standards. The results of such
                  audits shall be filed with the State Commissions. Prior to the
                  initial audit, AEP will conduct an informational meeting with
                  State Commissions regarding how its affiliates and affiliate
                  transactions will or have changed as a result of the proposed
                  merger.

         W.       If the Public Utility Holding Company Act of 1935 is repealed
                  or materially amended during the time this Agreement is in
                  effect, and equivalent jurisdiction is not given to another
                  federal agency, AEP will work with the State Commissions to
                  ensure that AEP continues to furnish the State Commission with
                  the appropriate information to regulate its jurisdictional AEP
                  operation company. The State Commission may establish its
                  reporting requirements regarding the nature of intercompany
                  transactions concerning the operating company and a
                  description of the basis upon which cost allocations and
                  transfer pricing have been established in these transactions.

9. ADEQUACY AND RELIABILITY OF RETAIL ELECTRIC SERVICE. See Attachment C for the
AEP/KENTUCKY POWER SERVICE QUALITY PROGRAM that has been agreed to by the
parties.

10. STATUTORY AND OTHER ISSUES. Provided the proposed merger is ultimately
consummated, AEP commits that upon issuance of any final and non-appealable
order from any state or federal commission addressing the merger that provides
benefits or imposes conditions on AEP that would benefit the ratepayers of any
jurisdiction, such net benefits and conditions will be extended to all other
retail customers to the extent necessary to achieve equivalent net benefits and
conditions to all retail customers of AEP.

11. CONTINUED PARTICIPATION. Nothing in this Agreement is intended to preclude
the Commission and its staff from addressing in a manner not inconsistent with
this Agreement issues raised in the FERC Docket No. 98-40-000.

12. ENFORCEABILITY. AEP and KPCO will not assert in any action to enforce an
order approving this Agreement that the Commission lacks the authority to have
the provisions of this Agreement enforced under Kentucky law.

Proposed Order in the form attached hereto as Attachment D. All of the terms and
agreements contained in the Proposed Order are to be interpreted consistent with
the provisions of this Agreement, which is to be attached to and incorporated by
reference in the Final Order issued by the Commission.

Effect and Use of Agreement

1. This Agreement shall not constitute nor be cited as precedent or deemed an
admission by any Party in any other proceeding except as necessary to enforce
its terms before the Commission, or any State Court of competent jurisdiction.
This Agreement is solely the result of compromise in the settlement process,
shall not constitute a concession of subject matter jurisdiction, and except as
expressly provided herein, is without prejudice to and shall not constitute a
waiver of any position that any of the Parties may take with respect to any or
all of the items resolved herein in any future regulatory or other proceedings
and, failing approval by this Commission, shall not be admissible or discussed
in any subsequent proceedings.

2. The evidence in this Case constitutes substantial evidence sufficient to
support the Agreement and provides an adequate evidentiary basis upon which the
Commission can make any finding of fact and conclusions of law necessary for the
approval of the Agreement, as filed.

3. The issuance of the Final Order shall terminate any further proceedings in
this Case.

4. In the event this Case is required to be litigated, the Parties expressly

AEP/Kentucky Power (the Company) has as one of its highest priorities a desire
to maintain and improve the quality and reliability of service to its customers.
The Company commits that current levels of customer service and service
reliability shall not degrade as a result of the merger and that it shall
undertake all reasonable efforts to improve the quality and reliability of its
service. In order to assure the Commission and Kentucky customers of continued
excellent service quality in the post-merger environment, the Company commits
and agrees to do the following:

1. To maintain the overall quality and reliability of its electric service at
levels no less than it has achieved in the calendar years 1995-1998. The Company
will provide service reliability reports annually indicating its calendar year
Kentucky Customer Average Interruption Duration Index (CAIDI) and Kentucky
System Average Interruption Frequency Index (SAIFI). These indices shall be
determined and reported, including all storms. Definitions for these measures
are included on page 3. On page 5 are listed Kentucky Power's annual SAIFI and
CAIDI performance for the years 1995 through 1998.

2. To provide annual Call Center performance measures for those centers which
handle Kentucky customer calls. These will include the Call Center Average Speed
of Answer (ASA), Abandonment Rate, and Call Blockage. Definitions for these
measures are also included on page 4.

         a)       The performance measures described in paragraphs 1 and 2 above
                  shall be provided by the end of May of the year following the
                  calendar year in question.

3. Will continue to completely inspect its Kentucky electric facilities every
two years and perform tree trimming, lightning arrest or replacement, animal
guarding and pole and cross arm replacements.

4. AEP/Kentucky Power management will compile outage data detailing each
circuit's reliability performance. In addition, by monitoring repeated outages
on a regular basis, the Company will identify and resolve reliability problems
which may go unnoticed by using CAIDI and SAIFI results. This data will be
coupled with feedback from district field personnel and supervision and
management concerning other locations and situations where the impact of outages
are quantified. This process will be used to develop a comprehensive work plan
each year which focuses efforts to improve service reliability. The Company will
undertake all reasonable expenditures to achieve the goal of limiting customer
outages.

5. Plans to continue to maintain a high quality workforce to meet its customers
needs.

6. Shall designate an employee or agent within Kentucky who will act as a
contact for retail consumers regarding service and reliability concerns and to
provide a contact for retail consumers for information, questions and
assistance. Such AEP/Kentucky Power representative shall be able to deal with
billing, maintenance and service reliability issues.

         a)       The company further commits to maintain in Kentucky a
                  sufficient management team to ensure that safe, reliable and
                  efficient electric service is provided and to respond to the
                  needs and inquiries of its Kentucky customers.

7. In the event the Commission adopts industry generic rules concerning customer
service standards, AEP/Kentucky Power shall have at its option, the right to
incorporate them into this agreement.

         a)       AEP/Kentucky Power will have the opportunity to revisit with
                  the Commission the agreed upon measure(s) should the Company
                  wish to propose a specific performance-based ratemaking
                  proposal provided the proposal either includes a reliability
                  measure(s) and/or a customer satisfaction survey measure that
                  contains service reliability as a component.

         b)       These standards can be changed during the term of this
                  agreement to reflect any performance-based ratemaking plans or
                  rules which the Commission adopts either for AEP/Kentucky
                  Power and/or generically for the electric utility industry.

8. If retail access is mandated by the Kentucky General Assembly and/or the
Commission and/or by federal legislation, AEP/Kentucky Power shall have the
right to petition the Commission for modifications to this service quality
agreement that are made necessary by the mandating of retail access.

         a)       Any such petition must establish the necessity of the proposed
                  modifications and provide appropriate protections to ensure
                  that AEP/Kentucky Power's quality of service will not decline.
                  The Commission will act upon the petition within 90 days or
                  the petition will be deemed to be automatically approved.

9. All prudent costs incurred to comply with the items contained in this
Agreement, once incurred, will constitute known and measurable expenses that
Kentucky Power shall have an opportunity to recover in accordance with
traditional ratemaking principles, through recognition of these costs in its
revenue requirement in future rate review.

                            AEP RELIABILITY MEASURES

1)       System Average Interruption Frequency Index (SAIFI) is defined as the
         number of customers interrupted divided by the number of customers
         served. It is calculated by the equation:

         SAIFI=            Number of customers interrupted
                -----------------------------------------------------------
                             Number of customers served

2)       Customer Average Interruption Duration Index (CAIDI) is defined as the
         number of customer hours of interruption divided by the number of
         customers interrupted. It is calculated by the equation:

         CAIDI=            Sum of all customer hours of interruption
                -----------------------------------------------------------
                             Number of customers interrupted

                            AEP CALL CENTER MEASURES

1)       Average Speed of Answer (ASA) is defined as the average time that
         elapses in seconds between the instant when a call is answered and the
         time it is connected to a Call Center representative (CSR) or an
         interactive voice recorder (IVR). It is calculated using the equation:

         Average  Speed of Answer = Time for all calls between call answer and
                (seconds)                      CSR/IVR connection
                                    -------------------------------------------
                                         Total number of calls made to the
                                                   Call Center

2)       Abandonment Rate is the percentage of callers who hang up before being
         connected to a Call Center representative (CSR) or an interactive voice
         recorder (IVR). It is calculated using the equation:

         Abandonment Rate =     {Total number of callers who hang up}
            (percent)      ----------------------------------------------- x 100
                           {Total number of calls made to the Call Center}

3)       Call Blockage is the percentage of non-outage call attempts which do
         not get connected to a Call Center (busy signal, etc.). It is
         calculated using the equation:

IN THE MATTER OF:

         JOINT APPLICATION OF KENTUCKY POWER COMPANY,         )
         AMERICAN ELECTRIC POWER COMPANY, INC.                )

         REGARDING A PROPOSED MERGER                          )

         On February 17, 1999, the Staff of the Public Service Commission of
Kentucky ("Commission") issued a letter stating staff's belief that the
Commission has jurisdiction under KRS 278.020 (5) to review the proposed merger
of Central and South West Corporation ("CSW") into American Electric Power
Company, Inc. ("AEP") and requested that Kentucky Power Company ("Kentucky
Power", "KPCO" or the "Company") advise in writing by March 8, 1999 of the date
AEP would file an application for Commission approval of "the indirect change in
control of Kentucky Power Company." On March 5, 1999 the Company issued a letter
notifying the Commission that it would file the requested application by April
15, 1999. The letter also indicated that the Company expected to provide the
Staff and the Commission with sufficient information to enable the Commission to
approve its application within the sixty (60) day period prescribed by the
statute. The letter further preserved the Company's legal arguments regarding
the application of KRS 278.020 to this merger.

         On April 15, 1999, the Company, AEP and CSW filed a Joint Application
with supporting testimony and work papers. The proceeding was designated P.S.C.
Case No. 99-149. On April 22, 1999, the Commission issued a letter indicating
that the Commission staff had reviewed the Company's application and found that
it met the minimum filing requirements.

         On May 4, 1999, the Attorney General, Office of the Rate Intervention
("Attorney General"), and Kentucky Electric Steel, Inc. ("KESI") were granted
full intervention in Case No. 99-149. On May 11, 1999, Kentucky Industrial
Utility Customers, Inc. ("KIUC"), was also granted full intervention in Case No.
99-149. These parties will be referred to herein collectively as the
"Intervenors."

         On April 22, 1999, a Technical Conference was held at the Commission's
offices. On May 4, 1999, May 11, 1999, May 17, 1999 and May 20, 1999 settlement
conferences were held at the Commission's offices. All parties to the proceeding
and the Commission staff were present and participated in the settlement
conferences.

         Having considered the evidence and being duly advised, the Commission
now finds:

         1. Notice and Jurisdiction. Due and timely notice of the hearing to
consider the settlement proposed by the parties was given. Kentucky Power is a
"utility" within the meaning of that term in KRS 278.010(3)(a) and is subject to
the jurisdiction of the Commission in the manner and to the extent provided by
the laws of the Commonwealth of Kentucky.

         2. The Settlement Agreement. As described in the Settlement Agreement,
a copy of which is attached hereto as Exhibit A and incorporated herein by
reference, the Settlement Agreement contains, among other things, provisions
regarding (a) net non-fuel merger savings; (b) fuel and purchased power merger
savings; (c) limitation on requests for stranded cost recovery; (d) allocation
of proceeds from the sale of facilities; (e) system integration agreements; (f)
Ohio Power waiver; (g) affiliate standards; (h) maintenance and enhancement of
the adequacy and reliability of retail electric service, including certain
reporting requirements; (i) settlement of the existing environmental surcharge
litigation (Kentucky Court of Appeal Case No. 98-CA-00137, 98-CA-01344,
98-CA-01417, 98-CA-01455); and (j) settlement of the pending six month

<PAGE>   43
review of KPCO's environmental surcharge in P.S.C. Case No. 98-624. The
Settlement Agreement was agreed to by all parties to this proceeding.

         The Settlement Agreement further provides that if the proposed merger
is ultimately consummated, AEP commits that upon issuance of any final and
non-appealable order from any state or federal commission addressing the merger
that provides benefits or imposes conditions on AEP that would benefit the
ratepayers of any jurisdiction, such net benefits and conditions will be
extended to all other retail customers to the extent necessary to achieve
equivalent net benefits and conditions to all retail customers of AEP.

         The Settlement Agreement also provides that, upon approval by the
Commission, the Intervenors, the Commission and its Staff shall not oppose the
proposed merger before FERC or oppose AEP's previously made merger-related
filings with the Securities and Exchange Commission.

         The Settlement Agreement further states that it shall not constitute
nor be cited as precedent or deemed an admission by any party in any other
proceeding except as necessary to enforce its terms before the Commission, or
any State Court of competent jurisdiction on these particular issues. The
Settlement Agreement provides that it is solely the result of compromise in the
settlement process, shall not constitute a concession of subject matter
jurisdiction, and except as expressly provided therein, is without prejudice to
and shall not constitute a waiver of any position that any of the parties
thereto may take with respect to any or all of the items resolved therein in any
future regulatory or other proceedings.

         The Settlement Agreement states that if the Commission does not approve
the Settlement Agreement in its entirety, it shall be null and void and deemed
withdrawn, unless such change is approved by the parties.

         At a hearing held May 28, 1999, Richard E. Munczinski, Senior Vice
President-Corporate Planning and Budgeting of American Electric Power Service
Corporation, the service corporation subsidiary of AEP, and Errol K. Wagner,
Director of Regulatory Affairs for Kentucky Power testified in support of
Commission approval of the Settlement Agreement. Mr. Munczinski discussed the
negotiating process which resulted in the Settlement Agreement and the public
benefits that would result from its approval. Mr. Wagner testified regarding the
mechanism by which the bill reductions will be implemented by Kentucky Power.

         During the course of this proceeding information about the proposed
merger was requested from and provided by Kentucky Power, AEP and CSW.
Additional information about the proposed merger has since been developed in the
course of FERC proceedings and proceedings before other state commissions. After
lengthy and detailed negotiations, Kentucky Power, CSW, AEP, the Attorney
General, Office for Rate Intervention, Kentucky Industrial Consumers, Inc. and
Kentucky Electric Steel have reached a unanimous agreement on terms and
conditions that help ensure that Kentucky consumers will fairly share in the
benefits achieved by the merger and that Kentucky consumers will be protected
against any detrimental effects. The Parties recommend that the Commission
approve the Settlement Agreement as a fair and just settlement of differences
regarding merger-related issues.

         Having reviewed the Settlement Agreement and the evidence relating
thereto, the Commission finds that the recommendation of the Parties should be
approved. The Commission further finds that the Settlement Agreement is a fair
and reasonable resolution of the merger-related issues of concern to the
Commission and the Intervenors and should be approved in its entirety without
modification.


                                       4
<PAGE>   45
         The Commission finds that AEP and Kentucky Power have and will retain
the financial, technical and managerial abilities to provide reasonable service.

         The Commission further finds that the proposed merger of AEP and CSW is
in accordance with the law, for a proper purpose and is consistent with the
public interest.

         IT IS THEREFORE ORDERED BY THE PUBLIC SERVICE COMMISSION OF KENTUCKY
that:

         1. The Settlement Agreement shall be and hereby is approved in its
entirely without modification and that the merger of AEP and CSW is approved
pursuant to KRS 278.020(4) and KRS 278.020(5).

         2. Kentucky Power shall implement the Net Merger Savings Credit Tariff
in the amounts shown in the tariff filed as Exhibit 2 to this Order, which
tariff is approved.

         3. American Electric Power, Inc. and Central and South West Corporation
will incur transaction, regulatory processing and transition costs to merge the
two companies. The Commission orders that the Kentucky retail jurisdictional
share of the estimated merger costs be deferred and amortized for recovery over
eight years. The amortization should begin with the date of the combination and
continue for eight years on a straight-line basis.

         4. The proposed regulatory plan is approved as are the steps necessary
to implement it, specifically:

                  a. the regulatory treatment of the fuel saving arising from
the integrated operations of AEP, CSW and Kentucky Power as set forth in the
Settlement Agreement;

                  b. Kentucky Power is authorized to include as an allowable
expense in cost of service the non-fuel merger savings, net of cost to achieve
and amortization of estimated costs to achieve as set forth in Attachment B to
the Settlement Agreement.

         5. Effective January 1, 2000, KPCO shall begin collecting the
environmental surcharge, including the costs of the Low Nox burners for the Big
Sandy generating plant's Unit No. 1 and Unit No. 2, in accordance with the
Opinion and Order of the Franklin Circuit Court dated April 30, 1998, as amended
by Opinion and Order dated May 14, 1998 in Consolidated Case Nos. 97-CI-00137,
97-CI-01138, 97-CI-01144 (except those portions of the decisions allowing
retroactive recovery of the surcharge).

         6. The Commission approves the settlement of the environmental
surcharge litigation (Kentucky Court of Appeals Case Nos. 98-CA-00137,
98-CA-01344, 98-CA-01417, 98-CA-01455 and 98 CA 002476) as described in the
Settlement Agreement and authorizes its counsel to execute the necessary
documents to dismiss the appeals and cross-appeals therein.

         7. The pending review of KPCO's environmental surcharge in P.S.C. Case
No. 98-624 shall be terminated and that proceeding is ordered closed without
adjustment to the surcharge.

         8. This Order shall be effective on and after the date of its approval.

                  net savings from prior periods. The B.A.F. will be determined
                  by dividing the difference between amounts which were expected
                  to be distributed and the amounts actually distributed from

                  KWH. The final B.A.F. will be applied to customer billings in
                  the second month following the effective date of a Commission
                  order changing the Company's base rates after Year 8 of this
                  tariff.

TERMS OF DISTRIBUTION

         1.       The total distribution to the Company's customers will, in no
                  case, be less than the sum of the amounts shown for the first
                  eight years above.

         2.       On or before the 21st of the first month of each distribution
                  year following Year 1, the Company will file with the
                  Commission a status report of the Net Merger Savings Credit.
                  Such report shall include a statement showing the amounts
                  which were expected to be distributed and the amounts actually
                  distributed in previous periods, along with a calculation of
                  the B.A.F. which will be implemented with customer billings in
                  the second month of that distribution year to reconcile any
                  previous over- or under-distributions.

         3.       The Net Merger Savings Credit shall be applied to the
                  customer's bill following the rates and charges for electric
                  service, but before application of the school tax, the
                  franchise fee, sales tax or similar items.

BY THE COMMISSION:
Camie J. Swanson-Hull, Commissioner
David E. Ziegner, Commissioner
Claudia J. Earls, Administrative Law Judge

         On June 29, 1998, the Commission on its own motion indicated an
investigation regarding the proposed merger of American Electric Power Company,
Inc. ("AEP") and Central and South West Corporation ("CSW"). AEP is the parent
company of Indiana Michigan Power Company ("I&M") which provides electric
utility service in the State of Indiana. The Order noted that AEP and CSW had
filed an application with the Federal Energy Regulatory Commission ("FERC") for
approval of the merger under Section 203 of the Federal Power Act.

         Petitions to intervene in this matter were filed by the Citizens Action
Coalition of Indiana, Inc. ("CAC"), Indiana Consumers For Fair Utility Rates (an
ad hoc group of industrial companies) ("ICFUR"), PSI Energy, Inc. ("PSI") and
Steel Dynamics, Inc.(1) These petitions were granted and these entities were
made parties to this proceeding. The Office of Utility Consumer Counselor
("OUCC") also participated in this proceeding.

         After receiving written comments of the parties on certain issues
relating to the proposed merger and after holding a preliminary hearing on
August 4, 1998, the Commissioner on September 2, 1998, issued an Order
appointing a negotiating team of members of the Commission Staff (the "Staff
Negotiating Team") to attempt to negotiate a settlement of the issues present in
this matter.

         By docket entries, I&M was directed to respond to various data requests
seeking information about the proposed merger and to provide to the Commission,
the Staff Negotiating Team and the other parties certain documents relating
thereto. I&M responded to the requests by providing voluminous information and
documents.

         During the course of this proceeding, status hearings were held at
which time the Staff Negotiating Team submitted reports regarding the process of
negotiations. On April 9, 1999, I&M and the Staff Negotiating Team submitted to
the Commission and

- -------------------------
(1) SDI subsequently withdrew from the proceeding.
<PAGE>   2
recommended for approval a Stipulation and Settlement Agreement (the "Settlement
Agreement") executed by I&M, AEP and the Staff Negotiating Team.

         On April 14, 1999, the parties to the Settlement Agreement prefiled
with the Commission prepared testimony and evidence in support of the Settlement
Agreement. A public evidentiary hearing on the Settlement Agreement was held on
April 19, 1999, at 10:00 a.m. in Room TC10 of the Indiana Government Center
South, Indianapolis, Indiana. At that time, the Settlement Agreement and
evidence relating thereto were accepted into the record.

         Based upon the applicable law and evidence herein, the Commission now
finds:

         (1) NOTICE AND JURISDICTION. Due legal and timely notice of the
settlement hearing was given and published as required by law. I&M is a "public
utility" within the meaning of that term in IC 8-1-2-1 and is subject to the
jurisdiction of the Commission in the manner and to the extent provided by the
laws of the State of Indiana. At the conclusion of the evidentiary hearing held
in this cause, CAC stated three bases for this Commission to determine that it
did not have the authority to approve the tendered Settlement Agreement. On
April 19, 1999, CAC filed a "Motion for Ruling in the Nature of a Judgment on
the Evidence." The three arguments raised by CAC are as follows:

(1)      The Commission lacks subject matter jurisdiction to approve the
         "Regulatory Plan" proposed in the Settlement Agreement.

(2)      The Commission lacks jurisdiction to approve the "Regulatory Plan"
         because I&M's customers have not received adequate notice that their
         future rates could be adjudicated in this proceeding.

(3)      Even if the Commission has the general subject matter jurisdiction and
         jurisdiction in this particular case to approve the proposed
         "Regulatory Plan," the rate-making treatment proposed in the Plan is
         contrary to law.

         On April 21, 1999, I&M filed its response. We will first discuss CAC's
arguments regarding the notice given to the public in this cause and then
address the arguments regarding the Commission's authority to grant the relief
requested in the Settlement Agreement.

         a. Notice of the scope of the proceeding. CAC contends that customers
did not receive adequate notice that future rates could be adjudicated in this
proceeding. Specifically, CAC argues that there is no reference to "rates" in
the public notice provided in this cause and secondly, that even the active
parties to this proceeding understood that the intended purpose of the
Commission investigation was to gather information for the purposes of
formulation of the Commission's position before the Federal Energy Regulatory
Commission, not to adjudicate issues as the regulator of I&M's retail rates and
charges.

         Indiana law clearly states that the IURC must have flexibility in
determining the appropriate content of public notices. "The complexity and
varied nature of regulatory


                                       2
<PAGE>   3
proceedings militate against the adoption of a more particularistic notice
standard; the Commission's Rule 8(b) provides the flexibility necessary for
case-by-case determinations of the appropriate content of the public notice to
be published." City of Evansville v. Southern Ind. Gas & Elec. Co., 339 N.E.2d
562, 578 (Ind. Ct. App. 1975). Our administrative code requires the caption of a
petition to describe in general terms all the relief being sought in the
petition, 170 IAC 1-1-8(b) (emphasis added). In this proceeding, customers were
given notice that "any and all matters relating to the merger" were subject to
the investigation. This broad notice certainly contemplates that issues
including but not limited to merger savings, merger cost allocation, and impact
on jurisdictional customers of the merged utility would be considered. We find
that the public notice issued in this proceeding was sufficient to notify
customers that the investigation may reach the issue of rate treatment. We also
note that, even where a public utility makes a complaint as to any matter
affecting its own rates or service, only reasonable notice is required, and
there is no necessity for specific public notice of all regulatory issues whose
ultimate resolution might independently affect an increase in a utility's rates.
See, e.g., City of Evansville v. Southern Ind. Gas & Electric Co., 339 N.E.2d
562, 578-579.

         The notice provided in this case stated that this was a Commission
investigation. Under the Commission's investigatory powers, the Commission has
the power and authority to issue orders consistent with its broad grant of power
from the legislature which is necessary to effectuate the regulatory scheme.
See, N. Ind. Pub. Serv. V. Citizens act. Coal., 548 N.E.2d 153 (Ind. 1989). In
its "Memorandum of Law in Support of Motion for Ruling in the Nature of Judgment
on the Evidence," CAC argues that "even the active parties to this proceeding
understood that the intended purpose of the Commission investigation was to
gather information...." p.7. The Commission's September 2, 1998 Order provided
notice to the parties that the Commission was moving from an informal
investigation pursuant to IC 8-1-2-58 to a formal adjudication pursuant to IC
8-1-2-59. The Commission had previously described the issues before it to
include "how the risks, costs and benefits of the merger should be shared among
the stockholders and the customers, both wholesale and retail, of AEP." Order,
June 29, 1998, Exhibit A, p.4, Item 4. CAC participates in the process. As Staff
witness Glazier stated at the hearing held in this Cause, "We are negotiating on
behalf of the almost six million people who we work for, Mr. Muller. And as you
know, you were part of the negotiation discussions." To have participated in the
settlement negotiations and then allege that the parties were unaware of the
scope of the proceedings is puzzling to the Commission.

         CAC also makes mention of the fact that I&M did not provide notice to
its customers of the potential rate impact of the Commission's investigation.
Yet, nowhere in its legal memorandum does CAC cite any authority that confers
upon I&M an affirmative duty to provide such notice. In addition, the Commission
would note that CAC has waived any such challenge to our jurisdiction. As the
Indiana Supreme Court found in City of New Haven v. Indiana Suburban Sewers,
Inc., (1972) 277 N.E.2d 361:

                  If the notice prescribed is prerequisite to jurisdiction of
                  the subject matter of the proceedings, the rule is otherwise,
                  as the right to challenge such jurisdiction can never be lost
                  or waived. Appellant has correctly stated such rule and
                  supported it with good authority, but we believe the


                                       3
<PAGE>   4
                  question here is not one of jurisdiction over the subject
                  matter of the proceedings. Such jurisdiction was established
                  when notice of the time and place of public hearing was given
                  more than ten (10) days prior to the date set for the hearing
                  as prescribed by the statue, Indiana Acts 1957, ch. 313,
                  Section 2, 1969 Supp. Burns Ind. Stat. Ann. Section 54-601c,IC
                  1971, 8-1-289. Having been thusly established, such
                  jurisdiction continued throughout the proceedings, including
                  the rehearing, and we believe that the ends of justice would
                  not be served by faulting proceedings by reason of a defect in
                  the form of notice, if such defect did in fact exist, when the
                  complaining party attended and participated therein. Clearly
                  the notice which Appellant insists should have been given
                  would not have benefited it and its omission did it no harm.

         Id., at p. 362-3.

         CAC also argues that it did not have full rights of discovery. It never
raised this concern throughout the investigation. All parties were invited to
submit proposed discovery requests to the Commission. The Commission then issued
data requests akin to discovery requests including data requests propounded by
CAC. At no time did CAC object in this procedure. On November 30, 1998, the
Commission issued a docket entry stating that it had reviewed AEP's responses to
its data requests, and giving all parties an opportunity to submit additional
data requests to the Commission for consideration. CAC provided no new data
requests. In addition, CAC is a party to the FERC action and was a party to the
FAC 40 S i subdocket before this Commission. CAC has had available to it all
discovery processes in both of those proceedings. This argument appears as
devoid of merit as the argument that CAC was without notice of the scope of the
proceeding.

         Having considered the arguments of the parties the Commission finds
that the public received proper notice of the proceedings held in this Cause and
that the Commission has complied with the applicable authority regarding the
procedural conduct of this proceeding.

         b. Commission's Jurisdiction to grant the requested relief. Throughout
CAC's "Memorandum" it argues that I&M is "recovering through rates" shareholder
savings. CAC's argument is misguided. I&M has agreed in the Settlement Agreement
to pass through 55% of the net merger savings immediately and automatically upon
consummation of the merger. Without this agreement, I&M could have maintained
its existing rates until either it successfully petitioned the Commission for a
change in its base rates or the Commission initiated either on its own or at the
request of another party and concluded an investigation into the reasonableness
of I&M's base rates.

         CAC also argues that the Settlement Agreement's allowances of the
referral and amortization over the eight-year period of the merger costs is
allowing the inclusion in customer rates of expenses based upon contingencies
that have not yet occurred. To support its proposition, CAC cites Citizens
Action Coalition v. Public Serv. Co. (Ind.


                                       4
<PAGE>   5
App. 1993) 612 N.E. 2d 199, 201. That case is readily distinguishable from this
case insomuch as that case dealt with the Commission's speculation regarding the
probability of passage of acid rain legislation. In the instant case, the
contingent event is the consummation of the merger. If there is no merger, there
is no effect of the Settlement Agreement. In this case, there is no speculation.
If the merger occurs, I&M is allowed to amortize the expenses associated with
the merger. If the merger does not occur, there will be no allocation of those
expenses and no rate impact. To adopt CAC's position would be to call into
question every municipal rate order this Commission has issued in the recent
past which allows for an increase in rates premised upon an increase in debt
service in anticipation of the issuance of bonds to fund a capital improvement
project. Generally the bonds have not been issued when the municipality
petitions for rate relief. Thus, the Commission in granting the rate relief is
premising the relief on the issuance of the bonds, a future contingency. Orders
on proposed but unconsummated transactions have occurred in the merger and/or
take-over context as well. For example, in our order in Cause No. 37962, issued
May 29, 1986, in a case involving the acquisition of the Zionsville waterworks
system by Zionsville Water Corporation, a subsidiary of Indianapolis Water
Company, the Commission approved the accounting methodology to be utilized upon
consummation of the transaction for the recording of the purchase, including an
acquisition adjustment. The transaction had not been consummated, and yet the
accounting treatment was approved. In addition, the Commission approved the
amortization of the acquisition adjustment as an "above-the-line" operating
expense recoverable through rates. Order, p.19. The Commission noted that such
treatment was consistent with a previous order involving Indiana Cities Water
Corporation, Cause No. 37579, Order issued June 12, 1985. In addition, in
several cases, future rate-making treatments were approved in advance of the
closing of the transaction, and in many of the cases, pre-approval of the
rate-making treatment was a condition for closing. See e.g., Indianapolis Gas
Co. and Westport Net Gas Corp., Cause No. 38302 issued January 20, 1988; West
Lafayette Water CO. and Green Meadows Util., Cause Nos. 39417, 38902 and 39166-U
issued September 23, 1962; and Indiana American Water Co. and Farmington
Utilities, Inc., Cause No. 40442, issued October 2, 1996.

         The final argument that CAC presents against the Settlement Agreement
is that it attempts to "bind" future Commissions with respect to various
expenses. As Indiana courts have stated on numerous occasions, the rate-making
process is a legislative not an adjudicatory process. See, e.g. Office of
Utility Consumer Counselor v. Public Service Company, 463 N.E.2d 499 (Ind. App.
3 Dist. 1984). There is no precedent set in one case for use in a subsequent
case. Res judicata principles apply when an administrative agency acts in a
judicial capacity, but do not apply when the agency acts in a legislative
capacity. See, Indiana Gas v. Utility Consumer Counselor, 610 N.E.2d 865 (Ind.
App. 5 Dist. 1993). In this case, the Settlement Agreement requests that the
Commission allow I&M to book certain expenditures. In any rate proceeding, the
Commission is allowed to presume a utility's costs are prudently incurred. See,
Anaheim v. Federal Energy Regulatory Commission, (D.C. Circuit, 1981) 669 F.2d
799). However, where a participant in a proceeding creates a doubt as to the
reasonableness of the expenditure, the burden of dispelling these doubts and of
proving the questioned expenditure falls to the utility. Id. Obviously, if the
Commission approves the Settlement Agreement and I&M is allowed to book certain
expenditures, any party to any subsequent proceeding may question the
reasonableness of any such expenses. CAC argues that by adopting our Staff's
recommendation to approve the Settlement Agreement, the Commission will be


                                       5
<PAGE>   6
mystically transformed into a proponent of the accounting treatment afforded the
expenditures in any subsequent rate proceeding. The adoption of a Staff
recommendation, however, does not transform the Commission into a proponent. As
the Appellate Court held in Board of Directors for Utilities v. Office of Util.
Consumer Counselor.



                  The statute does not limit the use of these reports by the
                  Commission and to the extent that they become a part of the
                  record and their contents may be utilized by the Commission,
                  they are evidence. Reliance on the reports does not
                  automatically transform the Commission into a proponent or
                  opponent in the proceedings. To hold otherwise would place
                  I.C. 8-1-1-5(a) in direct conflict with subsection (b), an
                  illogical result clearly not intended by the legislature. . .
                  . The reports are merely an additional tool to aid the
                  assimilation of factually complex and technical information.

         c. Conclusion. Having considered the arguments raised by CAC, the
Commission finds that due, legal and proper notice of this proceeding was given
as provided by law and that this Commission has jurisdiction over Petitioner and
the subject matter of this cause and has authority to approve the Settlement
Agreement if it is found o be in the public interest.

                  (4) PROVISIONS OF THE SETTLEMENT AGREEMENT. As described in
         the Settlement Agreement, a copy of which is attached hereto as Exhibit
         A, and incorporated herein by reference, the Settlement Agreement
         contains, among other things: (a) net non-fuel merger savings; (b) fuel
         and purchase power merger savings; (c) limitation on requests for
         stranded cost recover; (d) allocation of proceeds from the sale of
         facilities; (e) system integration agreements; (f) Ohio Power waiver;
         (g) regional transmission organization commitments; (h) affiliate
         standards; and (i) maintenance and enhancement of the adequacy and
         reliability of retail electric service, including certain reporting
         requirements.

         The Settlement Agreement further provides that if any other state
commission or any federal commission issues a final and non-appealable order
addressing the merger that provides benefits or imposes conditions that would
benefit ratepayers of another jurisdiction, AEP will extend equivalent net
benefits and conditions to all AEP retail customers.

         The Settlement Agreement also provides that, upon approval by the
Commission, neither the Commission nor its Staff shall oppose the proposed
merger before FERC or oppose AEP's previously made merger-related filings with
the Securities and Exchange Commission.

         The Settlement Agreement also states that it shall not constitute nor
be cited as precedent or deemed an admission by any party in any other
proceeding except as


                                       6
<PAGE>   7
necessary to enforce its terms before the Commission, or any State Court of
competent jurisdiction on these particular issues. The Settlement Agreement
provides that it is solely the result of compromise in the settlement process,
shall not constitute a concession of subject matter jurisdiction, and except as
expressly provided therein, is without prejudice to and shall not constitute a
waiver of any position that any of the parties thereto may take with respect to
any or all of the items resolved therein in any future regulatory or other
proceedings.

         The Settlement Agreement states that if the Commission does not approve
the Settlement Agreement in its entirety, it shall be null and void and deemed
withdrawn, unless such change is approved by the parties. However, the
Settlement Agreement does provide the Commission with the authority to address
matters ancillary or incidental to the agreement.

         At the settlement hearing, Robert C. Glazier, Director of Utilities for
the Indiana Utility Regulatory Commission, Richard E. Munczinski, Senior Vice
President-Corporate Planning and Budgeting of American Electric Power Service
Corporation, the service corporation subsidiary of AEP, and Kent D. Curry,
Director of Regulatory Affairs for I&M, testified in support of Commission
approval of the Settlement Agreement. Mr. Glazier and Mr. Munczinski discussed
the negotiating process which resulted in the Settlement Agreement and the
benefits that they believe would result from its approval. Mr. Curry testified
regarding the mechanism by which the bill reductions would be implemented by
I&M.

                  (5) COMMISSION FINDINGS. In our Order dated June 29, 1998, the
         Commission stated this investigation was commenced because the
         Commission believed that the proposed merger of AEP and CSW could have
         significant impact on the electric industry and customers in Indiana
         and across the region and the Commission was concerned about the
         proposed merger's effect on reliability of service and the development
         of independent system operators. During the course of this proceeding
         considerable information about the proposed merger was requested from
         and provided by I&M. Additional information about the proposed merger
         has been developed in the course of FERC proceedings and proceedings
         before other state commissions. After lengthy and detailed
         negotiations, I&M, AEP and the Staff Negotiating Team have reached
         agreement on terms and conditions which they allege will help ensure
         that Indiana consumers will fairly share in the benefits achieved by
         the merger and that Indiana consumers will be protected against any
         detrimental effects arising from the merger. The Staff Negotiating Team
         recommended that the Commission approve the Settlement Agreement as a
         fair and just settlement of differences regarding merger-related
         issues.

         At the hearing held in this cause, various parties expressed concern
regarding various aspects of the Settlement Agreement. Those concerns included:
(a) the mechanism for sharing of non-fuel merger savings; (b) the accounting
methodology to be used to allocate the merger costs and projected savings; (c)
the mechanism for the pass-through of fuel merger savings; (d) the assurances in
the Settlement Agreement that AEP will join a Regional Transmission Organization
("RTO"); (e) the affiliated standards; (f) the adequacy and reliability of AEP's
electric service; and (g) the public interest issues raised by the proposed
merger.


                                       7
<PAGE>   8
         The Commission will address each of these concerns individually.

         (a) Non-fuel merger savings tracker mechanism. CAC raised a concern
regarding the implementation of the Regulatory Plan, contained in the Settlement
Agreement and explained in more detail in the pre-filed testimony of AEP Witness
Curry. This Plan is used to pass certain non-fuel merger savings on to the
ratepayers of AEP. The procedural mechanism proposed to be used by AEP in this
Commission's 30-day filing procedure, an administrative procedure routinely used
to "track" expenses or savings back to the ratepayer. We note that as the 30-day
filing procedure is an informal process, it may need some enhancement to
alleviate some of the concern raised by CAC. We therefore find that in addition
to complying with the normal 30-day filing procedure, each filing made to track
the non-fuel merger savings should be accompanied by a verified statement
indicating that the facts contained in the filing are true to the best of AEP's
knowledge and that a copy of the 30-day filing has been served on each party to
this Cause. Our 30-day filing process includes an option for the Commission to
deny approval of any filing. The proponent of the filing may then petition the
Commission for approval of the requested relief at which time the Commission
would set any request for hearing. Nothing in this Order should be read to
preclude any party from objecting to any future 30-day filings by AEP. With
these safeguards, the Commission finds that the rider mechanism is acceptable to
implement the sharing of the non-fuel merger savings.

         (b) Accounting Methodology. As discussed in Finding No. 1(b)
hereinabove, the Settlement Agreement contemplates the Commission issuing an
Order in this cause approving the proposed accounting treatment of the merger
expenses and merger savings. Mr. Munczinski testified that the merger expenses
are currently accruing on the parents' books and that upon consummation of the
merger, the costs will be allocated to the operating companies' books. Pursuant
to the terms of the Settlement Agreement, these costs are to be included in
AEP's future FAC proceedings for purposes of determining whether I&M has
complied with the "earnings test" contained in I.C. 8-1-2-42(d)(3)("d(3) test")
In addition, for purposes of the return allowed in the d(3) test, the portion of
merger savings allocated to shareholders will be utilized in essence to increase
the allowable return.

         The Commission notes that these provisions will be of no consequence
unless at some point in the future, I&M is otherwise earning in excess of its
allowable return in a future FAC proceeding. In addition, the same treatment is
to be utilized should I&M file a base rate case. Pursuant to the terms of the
Settlement Agreement I&M may not file a base rate case with an effective date
prior to January 1, 2005. Considering the probability of either of these events
occurring, and consistent with the Commission's reasoning in Finding 1(b)
hereinabove, the Commission finds that the accounting methodology contained in
the Settlement Agreement should be approved.

         (c) Fuel Energy Savings Reflected Through the FAC (Fuel Adjustments
Clause). The Settlement Agreement states that fuel savings will be passed
through the fuel adjustment clause proceeding. In each future quarterly FAC
filing, AEP is to calculate the difference between the fixed fuel rate (9.2
mills per kWh) found in the Stipulation and Settlement Agreement in Cause No.
38702-FAC40-S1 and the actual incurred fuel cost, in mills. If the weighted
average of actual fuel costs are less than the


                                       8
<PAGE>   9
fixed fuel costs during the period of April 1, 1999 through December 31, 2003,
then that difference will be credited to customers, based on total kWh consumed,
as soon as possible after December 31, 2003. In this way, the fuel savings will
be passed along to the consumers upon the reconciliation contemplated in the FAC
40 S, 1 Order.

         (d) Regional Transmission Organization. The Indiana Utility Regulatory
Commission has consistently advocated the establishment of Regional Transmission
Operators (RTOs), such as Independent System Operators (ISOs), as a means of
mitigating the inherent market power of transmission owners and to foster a more
efficient and competitive wholesale power market. The mitigation of market power
by AEP's membership in an RTO is exceedingly important.

         To mitigate market power concerns and achieve greater reliability and
economic efficiency, the IURC has been supportive of efforts to form RTOs. While
we have been supporters of the Midwest Independent System Operator (MISO), we
have urged the FERC to make modifications to the MISO including, among other
things, to:

(1) Establish Power Exchanges (PXs) that would either be

         (a) separate organizations that coordinated with the RTO, or

         (b) a part of the RTO;

(2) vest the RTO with considerable authority over more of the traditional
control area responsibilities;

(3) ensure that coordination among RTOs, including pricing of services and
information protocols, are as efficient as possible.

         While the IURC recognizes many positive aspects of the MISO, the IURC,
in this cause as articulated by Staff Witness Glazier and in Commission
statements to the FERC, continues to express its concern that more progress is
needed to ensure independence, reliability and economic efficiency. One of the
most immediate concerns is the need to require participation of all transmission
owners in an RTO. To this end, the IURC has urged the FERC to use its authority
under the Federal Power Act (FPA) to mandate the participation of all
transmission owning utilities in an RTO. The IURC has also urged the FERC to
allow a certain amount of time for the industry to establish appropriate
boundaries for RTOs. If the industry can not agree on the appropriate boundaries
for any given RTO by a date certain, the IURC has suggested the FERC use its
authority to draw those boundaries.

         In previous testimony before the FERC and in this instant case, AEP's
position has been very similar to that espoused by the IURC. By way of example,
both AEP and the IURC have recognized the need for power exchanges. AEP has
suggested that RTOs assume greater authority over many traditional control area
responsibilities. AEP has also been a forceful advocate for large regional RTOs.

         Counsel Ronald Brothers, on behalf of intervenor CINergy in this cause,
sought to clarify the reasons for AEP's unwillingness to join the MISO. During
the course of the cross-examination, it became clear to the IURC that AEP and
CINergy are in agreement in many many respects. It does not seem that the areas
of disagreement are


                                       9
<PAGE>   10
insurmountable. By way of example, both CINergy and AEP agree that RTOs should
be as large as possible to provide greater reliability and efficiency. In this
regard, they both agree that an RTO could be as large as the entire eastern
interconnection. CINergy and AEP agree that gaps in the membership pose
significant problems. CINergy and AEP also both profess a sense of urgency.

         It is against this backdrop that the IURC has evaluated this Settlement
Agreement. Certainly, getting AEP to commit to joining an RTO is a major
accomplishment and AEP and other parties should be commended for their strides
in this regard. The IURC will be assertive before the FERC to ensure that AEP
joins an RTO and, to the maximum extent possible, that the RTO satisfies the
conditions espoused by the IURC. The IURC is satisfied that nothing in this
agreement prevents the IURC from advocating these concerns to the FERC, or
advocating these positions in any other forum, or assisting the parties in
bridging the remaining differences.

(e) Affiliate Standards. Paragraph 8 of the Stipulation and Settlement Agreement
provides for Affiliate Standards between the regulated and non-regulated
affiliates of the merged company. Specific provisions of the Affiliate Standards
include:


(1)      Principles for preventing cross-subsidization and/or cost shifting
         among the regulated and non-regulated affiliates and among the various
         regulatory jurisdictions in which the merged company will operate.

(2)      Guaranteed Commission access to employees, officers, books and records
         of any affiliate of the jurisdictional AEP operating company.

(3)      An AEP operating company shall not allow a non-utility affiliate to
         obtain credit under any arrangement that would permit a creditor, upon
         default, to have recourse to the operating company's assets.

(4)      Any untariffed, non-utility service provided by an AEP operating
         company or affiliated service company to any affiliate shall be
         itemized in a billing statement pursuant to a written contract or
         written agreement. Contracts between the AEP operating company and
         non-utility affiliates must be filed with the Commission.

(5)      The clear division of AEP operating company personnel, facilities and
         information from affiliated non-regulated wholesale generating or
         marketing personnel, facilities and information.

(6)      AEP will designate an employee who will act as a contact for the State
         Commission and consumer advocates seeking data and information
         regarding affiliate transactions and personnel transfers.

(7)      AEP will designate an employee who will act as a contact for retail
         consumers for information, questions and assistance.

(8)      AEP will inform the State Commission at least thirty days before making
         a filing at the FERC or SEC.

(9)      Violations of the provisions of the Affiliate Standards are subject to
         the enforcement powers and penalties at the State Commissions.

(10)     AEP will contact with an independent auditor who will conduct biennial
         audits for eight years after merger consummation of affiliated
         transactions to determine compliance with these affiliate standards.
         The results of such audits will be filed with the State Commissions.
         Prior to the initial audit, AEP will conduct an


                                       10
<PAGE>   11
         informational meeting with State Commissions regarding how its
         affiliates and affiliate transactions will have changed as a result of
         the proposed merger.

(11)     If the Public Utility Holding Company Act of 1935 ("PUHCA") is repealed
         or materially amended during the time this agreement is in effect and
         equivalent jurisdiction is not given to another federal agency, AEP
         will work with the State Commissions to ensure that AEP continues to
         furnish the State Commission with the appropriate information to
         regulate its jurisdictional AEP operating company.

         During the Commission hearing AEP witness Richard E. Munczinski and
Staff Negotiating Team witness Robert C. Glazier were questioned on the various
provisions of the Affiliate Standards. Both witnesses were asked why the
definition of affiliate in the Stipulation and Settlement Agreement differed
from the definition contained in I.C. 8-1-2-49. Both witnesses responded that
the difference was unintentional and not designed to circumvent any Commission
rule or standard.

         Mr. Munczinski was asked a number of questions during the hearing
designed to clarify various provisions of the Affiliate Standards section of the
Stipulation and Settlement Agreement. Subsection A3 of the Affiliate Standards
addresses the recovery of just and reasonable costs from the various regulatory
jurisdictions. Mr. Munczinski explained that this provision protected AEP from
just and reasonable costs being left unallocated or stranded. Mr. Munczinski
testified that these costs would include "particularly those [costs] that apply
to affiliated transactions, so that the parties have agreed that what should be
included in the cost of service would be those affiliated transaction costs that
meet the guidelines that are in this agreement, that the company should be made
whole. . ." In return, AEP pledges that no more than one hundred percent of the
cost will be allocated on an aggregate basis to the various regulatory
jurisdictions. Further, Mr. Munczinski committed that if a State Commission
failed to allow the recovery of just and reasonable affiliated transaction
costs, AEP would not seek recovery of those stranded costs from other
jurisdictions.

         Counsel for CAC questioned Mr. Munczinski on the terms and requirements
of the independent audit addressed in Section V of the Affiliate Standards. Mr.
Munczinski explained that the audit would be designed to test each provision of
the Affiliate Standards to ensure AEP compliance. Further, that prior to the
initial audit, AEP would conduct informational meetings with the affected State
Commission to allow them to input on the audit requirements. AEP also pledged to
file an audit plan with each State Commission prior to the commencement of the
independent audit.

         Questions from the bench regarding Section W of the Affiliate Standards
clarified that if PUCHA were repealed, AEP would continue to meet all
appropriate reporting requirements. AEP committed to work with the State
Commissions to determine what information would be reported to the Commission,
including an allocation of jurisdictional costs. Mr. Munczinski assured the
Commission that it was not AEP's intention to circumvent any Commission laws or
requirements upon the repeal of PUCHA.

         Having reviewed the Affiliated Standards the Commission finds that they
are reasonable and should provide more protection to AEP's Indiana customers
than the current state of regulation. AEP should be advised that in determining
an "affiliate" it


                                       11
<PAGE>   12
should use the definition contained in Indiana Code. AEP should also file an
audit plan with the Commission five days prior to commencing the independent
audit.

         (f) Reliability of Service. This Commission is very concerned that the
reliability, quality and adequacy of electric service provided by AEP not
deteriorate as a result of this merger. The Settlement Agreement addresses these
concerns on page 11, rhetorical paragraph 9 and through the reporting
requirements contained in Attachment C to the Settlement Agreement. The
reporting requirements consist of annual reports on two reliability measures,
known as SAIFI (System Average Interruption Frequency Index) and CAIDI (Customer
Average Interruption Duration Index), and three call center measures, delineated
as Average Speed of Answer, Abandonment Rate, and Call Blockage. These reports
are to be provided to the IURC by the end of May for the preceding calendar
year. These reports will provide an indication of AEP's ongoing reliability,
quality and adequacy of electric service.

         This Commission was troubled by the lack of quantification of any
benchmark against which to assess these measures to see if reliability, quality
and adequacy of electric service is being maintained or enhanced. Attachment C
of the Settlement Agreement indicated only that "Indiana Michigan Power will
maintain the overall quality and reliability of its electric service at levels
no less than it has achieved in the past decade." Responding to questions from
the bench, both AEP witnesses Munczinski and Curry testified that AEP would be
willing to file with the Commission the historical reliability and call center
measures, in a form essentially similar to that contained in Attachment C for
the last ten years, provided that such data exists. We find that AEP shall file
all such historical data that exists with the Commission's Engineering Division
within ninety (90) days of the date of this October.

         (g) Public Interest. The theory of law creating the Commission is that
"it shall be conscientiously and impartially administered by a body composed of
a personnel especially qualified by knowledge, training and experience
pertaining to the subject-matter committed to it . . . consonant with reasonable
fairness and substantial justice according to legislative mandate, and the
circumstances shown relative to its effect in the future on the utility's
ability to serve the interest and convenience of the public, the cost and
expense to the parties interested being an element for consideration." In re
Northwestern Indiana Tel. Co., 201 Ind. 667 (1929), at p. 674-5. When asked by
counsel for CAC for a definition of "public interest," Staff witness Glazier
stated that it was the balancing of the interests of economic development,
employment and the effectiveness of regulation. Case law has stated that the
Commission is to balance the interests of the affected utility and the public.

      In Mr. Glazier's Staff Report admitted into the record of this cause he
stated that "[I]t appears that employment in Indiana will not be negatively
impacted as a result of the proposed merger." Report, p.11. At the hearing held
in this cause, Mr. Munczinski stated that "if there are affected employees [in
Indiana], they would be at the management level in the service corporation or at
the highest level of management in Indiana Michigan Company. What we have
excluded would be the field personnel. I think we're pretty sure that in Indiana
it would be all the IBEW workers, union workers, customer service
representatives, things like that. But I couldn't, for instance, guarantee the
legal positions or the rates director position." Later in Mr. Munczinski's
testimony, he referred


                                       12
<PAGE>   13
to Mr. Flaherty's testimony in the Texas Docket. In that Docket, as Mr.
Glazier's staff report alludes to, Mr. Flaherty stated that there "are no
current plans to close any facilities in Indiana as a result of the AEP/CSW
merger." Report, p.11. The representation by AEP that no facilities will be
closed in Indiana and that no IBEW worker, union worker, or customer service
representative will lose their job, is critical to this Commission's
consideration of this merger.

         The Settlement Agreement left at least two critical terms undefined.
One undefined term is "bulk transmission facilities." The other is "consummation
of the merger." The Commission is aware of the difficulties in defining the term
"bulk transmission facilities." As was explained at the hearing, there is a
potential conflict between the states and FERC regarding the definition of
transmission facilities giving rise to a conflict regarding jurisdiction of the
transfer of those assets. AEP should be aware that this Commission intends to
actively participate in FERC proceedings and this Commission will not readily
cede its control over the transfer of transmission facilities. In our opinion,
IC 8-1-2-83 is applicable to the transfer of assets. This Commission intends, as
we previously stated herein, to be assertive before the FERC to ensure that AEP
joins a FERC-approved RTO. We do not anticipate that the failure to define the
term "bulk transmission facilities" will be utilized by AEP to thwart in any way
the effort to establish a regional RTO. "Consummation of the merger" shall be
defined as the day on which CSW shares are converted to AEP shares. AEP should
immediately notify the Commission of this occurrence.

         Given our task of balancing the interests of all of Indiana, the
Commission finds that approval of the Settlement Agreement is in the public
interest. Approval serves the interest and convenience of the public, and the
enormous cost in both time and money to continue litigating this matter on the
state and federal level will be diminished.

         (h) Conclusion. At the conclusion of the hearing held in this cause,
the OUCC's counsel made the following statement, "We are very appreciative of
all the efforts that the Commission staff put into this negotiation. I know it
is a very complex and arduous task for them, and they did a good job, and
although the OUCC did not sign off on the agreement, it does not take away from
our belief that the Commission staff did everything they could to reach an
agreement that they thought was the best for the ratepayers of I&M." We join in
the OUCC's recognition of the efforts made by the Commission 's Staff
negotiating team and by AEP to reach a settlement that resolved many of the
complex issues arising from this merger. It is the Commission's belief that
whole no party is ever 100 percent satisfied by the results of a settlement, the
negotiating process presents opportunities to raise issues which might otherwise
remain unaddressed in a litigated proceeding.

         Having reviewed the Settlement Agreement and the evidence relating
thereto and having considered all evidence submitted in this cause, the
Commission finds that the recommendation of the Staff Negotiating Team should be
approved. The Commission further finds that the Settlement Agreement is a fair
and reasonable resolution of the merger-related issues of concern to the
Commission and should be approved consistent with the findings herein which
approve the Settlement Agreement while also addressing matters incidental or
ancillary thereto.

IN THE MATTER OF THE INVESTIGATION            )
ON THE COMMISSION'S OWN MOTION                )
INTO ANY AND ALL MATTERS RELATING             )          CAUSE NO. 41210

ELECTRIC POWER, INC. AND CENTRAL              )
AND SOUTH WEST CORPORATION                    )


                      STIPULATION AND SETTLEMENT AGREEMENT

On June 29, 1998, the Indiana Utility Regulatory Commission ("IURC" or
"Commission") initiated this investigation regarding the proposed merger of
American Electric Power Company, Inc. ("AEP"), the parent company of Indiana
Michigan Power Company ("I&M"), and Central and South West Corporation ("CSW").
On September 2, 1998, the Commission appointed a Staff Negotiating Team "to
attempt to negotiate a settlement of the issues presented in this cause." In a
Docket Entry dated November 30, 1998 the presiding officers directed that "any
negotiated settlement resolving the issues presented in this Cause should be
filed with the Commission on or before March 5, 1999....." The Commission
extended that deadline at the request of the Staff Negotiating Team eventually
to April 12, 1999.

Solely for the purposes of compromise and settlement of the issues in this
proceeding, Indiana Michigan Power Company, which does business in Indiana as
American Electric Power and the Staff Negotiating Team (collectively referred to
as the "Parties") have met and reached a settlement agreement ("Agreement")
which they hereby submit and recommend for approval to the Commission. If the
Commission does not approve the settlement agreement in its entirety and
incorporate it in the Final Order, the proposed Agreement shall be null and void
and deemed withdrawn, unless such change is agreed to by the Parties.

                              SETTLEMENT AGREEMENT

WHEREAS AEP and CSW have filed various applications before federal and state
agencies seeking approvals necessary to consummate a proposed merger of the two
companies, and

WHEREAS AEP, I&M and the Staff Negotiating Team have met and explored over a
period of months various issues related to the proposed merger and their
agreements and differences regarding the effects of the proposed merger on
competition between electricity providers and on the terms and conditions under
which retail electric utility service is provided, and

WHEREAS AEP, I&M and the Staff Negotiating Team recognize the costs and
uncertainty of litigation and the desirability of consensual voluntary
resolution of their differences and the legitimate interest and good faith of
each of the parties in achieving the objectives each desires to achieve, and


                                       1
<PAGE>   17
WHEREAS the Staff Negotiating Team is authorized to make recommendations to the
IURC regarding a fair and just settlement of differences in the public interest,

The Parties agree as follows:

The Staff Negotiating Team will recommend to the IURC that the following
Agreement be adopted by the Commission in an order or other appropriate formal
action that references this Agreement or incorporates all of the provisions
thereof. Where appropriate, the Commission action may address or reserve other
matters ancillary or incidental to the matters addressed in this Agreement, for
immediate or future disposition, in a manner not inconsistent with the
Agreement.

All appropriate terms are defined in the "Definitions" section of the Agreement.

THE IURC and STAFF:

1. Will not oppose the proposed merger pending before the Federal Energy
Regulatory Commission ("FERC").

2. Will not oppose AEP's filings previously made at the United States Securities
and Exchange Commission ("SEC") in connection with the proposed merger, together
with any non-material changes or supplements thereto.

AEP, or its Indiana jurisdictional AEP operating company, conditional on merger
consummation will:

1. REGULATORY PLAN. I&M will implement net merger savings reduction riders that
will reduce bills to customers by the annual amounts shown in Attachment A
beginning with the first revenue month after the consummation of the merger. The
annual bill reduction amounts shown in Attachment A will be allocated to rate
classes based upon total revenues, excluding fuel cost adjustment, and credited
to customers' bills through the application of a per kilowatt hour factor
specific to each rate class. Each individual year's bill reduction will apply
for a twelve-month period except for an adjustment during each third quarter to
reconcile actual kWh sales and projected kWh sales for the prior year. The last
reduction will continue to apply in years following the end of year eight until
base rates for the operating company are changed.

The merger savings and costs are based on estimated values included in AEP's
filing with FERC in Docket No. EC98-40-000.

Notwithstanding any base rate proceeding during the eight-year period after the
consummation of the merger, the annual amounts shown in Attachment A will remain
in effect.

I&M must implement the above bill reductions in the manner and amounts described
above notwithstanding any changes to the current regulatory structure in
Indiana. In the event that retail electric deregulation legislation is
implemented in Indiana, or if there is any unbundling or restructuring, I&M
shall continue to apply the regulatory plan's provisions to regulated rates of
its Indiana customers.


                                       2
<PAGE>   18
Any legislatively mandated adjustments to base rates, of any kind, that are part
of any retail electric deregulation legislation implemented in Indiana shall not
diminish or offset, but shall be in addition to, the bill reductions established
in this proceeding.

Subject to this agreement, AEP and I&M will defer and amortize their Indiana
jurisdictional estimated merger related costs-to-achieve over an 8-year recovery
period. Costs to achieve the merger are those costs incurred to consummate the
merger and combine the operations of AEP and CSW. These costs include, but are
not limited to, investment banking fees; consulting and legal services incurred
in connection with obtaining regulatory and shareholder approvals; transition
planning and development costs; employee separation costs including severance
costs, change-in-control payments and retaining costs; and facilities
consolidation costs. The IURC will issue accounting orders or other orders
necessary to authorize the deferral and amortization of merger costs.

In any proceeding to change base rates for I&M to become effective after the
consummation of the merger, the following rate treatment will be reflected:

                  A.       Estimated non-fuel merger savings, net of costs to
                           achieve will be included in cost of service as an
                           allowable expense in order to avoid duplication and
                           to continue to provide shareholders with their share
                           of the net savings. The amount to be included in the
                           cost of service shall be based upon the test year
                           period. (See Attachment B)

                  B.       Amortization of estimated costs to achieve will be
                           included in cost of service as an allowable expense.
                           The amount to be included in the cost of service
                           shall be based upon the test year period. (See
                           Attachment B)

In addition, the net merger savings allocated to the shareholders will be
excluded from the earnings test in determining I&M's compliance with the
provisions of I.C. 8-1-2-42(d)(2) and (3).

To mitigate potential stranded investment, I&M will increase the funding for the
provision of paragraph 21 of the settlement agreement approved by the Commission
in Cause No. 38702-FAC40-S1 in the additional amount of $5.5 million annually
starting January 1, 2001 for a three-year period ending December 31, 2003. The
rate filing limitation in paragraph 8 of that settlement agreement is extended
by one year to January 1, 2005. In addition, I&M will abide by the provisions of
paragraphs 8, 9 and 10 of that settlement agreement, regardless of the outcome
of litigation in that cause.

2. FUEL MERGER SAVINGS. All savings of fuel and purchased power expenses
resulting from the merger shall benefit retail customers through existing fuel
clause recovery mechanisms applied by State Commissions. In circumstances when
one or more AEP operating companies in one AEP zone are supplying power to the
other AEP zone, and as a result the supplying zone needs to purchase replacement
power to serve its native load, AEP shall hold harmless the native load
customers of the supplying zone from any price differential between the
replacement power and the system power supplied to the other zone. Similarly, if
one or more AEP operating companies in one AEP zone are supplying power to the
other AEP zone, and as a


                                       3
<PAGE>   19
result, the supplying zone loses the opportunity to sell power at a price higher
than received from the zone being supplied, AEP shall credit the supplying zone
for the foregone revenues.

3. STRANDED COSTS. AEP and its operating companies agree not to seek or recover
any stranded costs associated with the operating companies of one AEP zone from
the retail customers of the other AEP zone.

4. PROCEEDS OF FACILITY SALES. Any proceeds from the sale of facilities shall go
to the AEP operating company in whose rate base the facilities are included, for
further disposition in accordance with the rules and orders of the regulatory
authorities whose jurisdiction encompasses the ultimate disposition of such
proceeds.

5. SYSTEM INTEGRATION AGREEMENTS. To mitigate any perceived impacts of the
merger on AEP's ability to exercise market power, AEP proposed in its FERC
merger application a mitigation plan. To protect retail customers, AEP agrees to
hold harmless the retail customers from any mitigation plan included in any FERC
order approving the merger of AEP-CSW. To implement this Agreement in any
general retail electric rate proceeding commenced by the filing of a petition on
or after the date of this Agreement, in which an AEP operating company requests
a change in its basic rates and charges, or in any other proceeding where so
ordered by the State Commission, AEP shall have the burden therein to prove that
such requested rate relief does not reflect mitigation-related costs.

AEP commits to file any allocation of the cost of new, modified or upgraded
generation or transmission facilities whose costs will be subject to the System
Integration Agreement or the System Transmission Agreement with the FERC and to
notify each State Commission of any such filing at the time it is made.
Notification to each State Commission will include an estimate of the cost of
construction, an explanation of the reasons for constructing the facilities,
studies supporting the construction of the facilities, and a proposed allocation
of the facilities' costs. If AEP plans to purchase an in-service facility or
already constructed and soon-to-be-in-service facility, AEP will follow the
above described procedures and will include as part of the notification to the
State Commission an explanation of the circumstances causing the AEP operating
company to make the purchase in question.

6. REGULATORY AUTHORITY. AEP agrees not to seek to overturn, reverse, set aside,
change or enjoin, whether through appeal or the initiation or maintenance of any
action in any forum, a decision or order of a State Commission based on the
assertion that the authority of the Securities and Exchange Commission as
interpreted in Ohio Power Co. v. FERC, 954 F.2d 779 (D.C. Cir. 1992) cert.
denied, 498 U.S. 73 (1992) impairs the State Commission's ability to examine and
determine the reasonableness of non-power affiliate transaction costs to be
passed to retail customers. The parties agree that the Ohio Power waiver does
not include waiver of any arguments that AEP may have with respect to the
reasonableness of SEC approval cost allocations. AEP will provide each State
Commission with notice at least 30 days prior to any filings that propose new
allocation factors with the SEC. The notice need not be in the precise form of
the final filing but shall include, to the extent information is available, a
description of the proposed factors and the reasons supporting such factors. AEP
and State Commission Staff will make a good-faith attempt to resolve their
differences, if any, in advance of a filing being made at the SEC.

<PAGE>   20
7. REGIONAL TRANSMISSION ORGANIZATION

         A.       Prior to December 31, 2000, AEP will file with the FERC an
                  unconditional application, consistent with the RTO agreement
                  and tariff, to transfer the operation and control of its bulk
                  transmission facilities in Indiana, Michigan, Kentucky, Ohio,
                  Tennessee, Virginia and West Virginia owned, controlled and/or
                  operated by AEP to the Midwest Independent Transmission System
                  Operator, Inc. or another FERC-approved Regional Transmission
                  Organization directly interconnected with AEP transmission
                  facilities. Provided that, if, by June 30, 2000, there is
                  pending before the FERC for approval an RTO to which AEP is a
                  signatory that includes two or more directly interconnected
                  control areas, at least one of which is not affiliated with
                  AEP, the December 31, 2000 date shall be extended to the date
                  that is 75 days after the date on which the FERC issues an
                  order either approving or disapproving the RTO.

         B.       AEP shall endeavor to incorporate equitable reciprocal pricing
                  arrangements with contiguous RTOs in the Alliance RTO or any
                  other filing to which AEP is a signatory seeking FERC approval
                  of the formation of a new RTO.

         C.       AEP will provide generation dispatch information necessary for
                  RTOs to monitor the effect of such dispatch on the loading of
                  that RTO's constrained transmission facilities. This
                  information must be provided to any RTO of which AEP is a
                  member, and to RTOs providing service over any transmission
                  facilities directly interconnected with the AEP east zone
                  transmission facilities. Each of these RTOs shall determine
                  the format, quantity and timing of these data as necessary to
                  perform this monitoring function. The information provided by
                  AEP shall be equivalent to that provided by all parties, which
                  have control of the dispatch of generation facilities, taking
                  service from these RTO(s) and shall be subject to appropriate
                  confidentiality provisions.

         D.       AEP believes that its RTO commitment, as defined in this
                  document, is in keeping with its goal of achieving a large,
                  economically efficient RTO in the Eastern Interconnection.

         E.       Nothing in this Agreement precludes the Commission, or its
                  staff from actively participating in any proceedings at the
                  FERC arising from any RTO filings made by AEP. However the
                  Commission and its staff commits that it will not offer such
                  participation as a reason to delay the consummation of the
                  merger or to advocate a position before FERC inconsistent with
                  Paragraph A above.

8. AFFILIATE STANDARDS. The following affiliate standards shall apply from the
date of closing of the merger until new affiliate standards imposed by state
legislation or State Commission action become effective.

         A.       The financial policies and guidelines for transactions between
                  an AEP operating company and its affiliates shall reflect the
                  following principles:

                                       5
<PAGE>   21
         1.       An AEP operating company's retail customers shall not
                  subsidize the activities of the operating company's
                  non-utility affiliates or its utility affiliates.

         2.       An AEP operating company's costs for jurisdictional rate
                  purposes shall reflect only those costs attributable to its
                  jurisdictional customers.

         3.       These principles shall be applied to avoid costs found to be
                  just and reasonable for rate-making purposes by the affected
                  State Commission being left unallocated or stranded between
                  various regulatory jurisdictions, resulting in the failure of
                  the opportunity for timely recovery of such costs by the
                  operating company and/or its utility affiliates; provided,
                  however, that no more than one hundred percent of such costs
                  shall be allocated on an aggregate basis to the various
                  regulatory jurisdictions.

         4.       An AEP operating company shall maintain and utilize accounting
                  systems and records that identify and appropriately allocate
                  costs between the operating company and its affiliates,
                  consistent with these cross-subsidization principles and such
                  financial policies and guidelines.

         B.       Each State Commission shall have access to the employees,
                  officers, books and records of any affiliate of its
                  jurisdictional AEP operating company to the same extent and in
                  like manner that each such State Commission has over a public
                  utility operating within the state in which such State
                  Commission exercises its regulatory authority if the affiliate
                  had engaged in direct or indirect transactions with the
                  jurisdictional AEP operating company. If such employees,
                  officers, books and records can not be reasonably made
                  available to a State Commission, then upon request of a State
                  Commission, the AEP operating company shall, in accordance
                  with state reimbursements rules, reimburse the State
                  Commission for appropriate out-of-state travel expenses
                  incurred in accessing the employees, officers, books and
                  records. Each AEP operating company shall maintain, in
                  accordance with generally accepted accounting principles,
                  books, records, and accounts that are separate from the books,
                  records, and accounts of its affiliates, consistent with Part
                  101 - Uniform System of Accounts Prescribed for Public
                  Utilities and Licensees Subject to the Provisions of the
                  Federal Power Act. Any objections to providing all books and
                  records must be raised before the State Commission and the
                  burden of showing that the request is unreasonable or
                  unrelated to the proceeding is on the AEP operating company.
                  The confidentiality of competitively sensitive information
                  shall be maintained in accordance with each State Commission's
                  rules and regulations.

         C.       In accordance with generally accepted accounting principles
                  and consistent with state and federal guidelines, an AEP
                  operating company shall record all transactions with its
                  affiliates, whether direct or indirect. An AEP operating
                  company and its affiliates shall maintain sufficient records
                  to allow for an audit of the transactions involving the
                  operating company and its affiliates. Asset transfers from an
                  AEP operating company to a non-utility affiliate and asset


                                       6
<PAGE>   22
                  transfers from a non-utility affiliate to an AEP operating
                  company shall be at fully distributed costs in accordance with
                  current Securities and Exchange Commission (SEC) issued
                  requirements or other statutory requirements if the SEC has no
                  jurisdiction.

         D.       An AEP operating company shall not allow a non-utility to
                  obtain credit under any arrangement that would permit a
                  creditor, upon default, to have recourse to the operating
                  company's assets. The financial arrangements of an AEP
                  operating company's affiliate are subject to the following
                  restrictions unless otherwise approved by that operating
                  company's State Commission.

         1.       Any indebtedness incurred by a non-utility affiliate will be
                  without recourse to the operating company.

         2.       An AEP operating company shall not enter into any agreements
                  under terms of which the operating company is obligated to
                  commit funds in order to maintain the financial viability of a
                  non-utility affiliate.

         3.       An AEP operating company shall not make an investment in a
                  non-utility affiliate under circumstances in which the
                  operating company would be liable for the debts and/or
                  liabilities of the non-utility affiliate incurred as a result
                  of acts or omissions of a non-utility affiliate.

         4.       An AEP operating company shall not issue any security for the
                  purpose of financing the acquisition, ownership or operation
                  of a non-utility affiliate.

         5.       An AEP operating company shall not assume any obligation or
                  liability as guarantor, endorser, surety, or otherwise, in
                  respect of any security of a non-utility affiliate.

         6.       An AEP operating company shall not pledge, mortgage or
                  otherwise use as collateral any assets of the operating
                  company for the benefit of a non-utility affiliate.

         7.       AEP shall hold harmless the retail customers of an AEP
                  operating company from any adverse effects of credit rating
                  declines caused by the actions of non-utility affiliates.

Transactions between AEP operating companies and affiliates involving a money
pool for the financing of short-term funding requirements are exempt from the
requirements of this paragraph. Further, the provisions of this paragraph would
not preclude AEP operating companies from issuing securities or assuming
obligations related to their existing coal subsidiaries.

         E.       Any untariffed, non-utility service provided by an AEP
                  operating company or affiliated service company to any
                  affiliate shall be itemized in a billing statement pursuant to
                  a written contract or written arrangement. The AEP operating
                  company and any affiliated service company shall maintain and
                  keep available for


                                       7
<PAGE>   23
                  inspection by the State Commission copies of each billing
                  statement, contract and arrangement between the AEP operating
                  company or affiliated service company and its affiliates that
                  relate to the provision of such untariffed non-utility
                  services.

         F.       Any good or service provided by a non-utility affiliate to an
                  AEP operating company shall be by itemized billing statement
                  pursuant to a written contract or written arrangement. The
                  operating company and non-utility affiliate shall maintain and
                  keep available for inspection by the State Commission copies
                  of each billing statement, contract and arrangement between
                  the operating company and its non-utility affiliates that
                  relate to the provision of such goods and services in
                  accordance with applicable State Commission retention
                  requirements.

         G.       Employees responsible for the day-to-day operations of the AEP
                  operating companies and those of affiliated exempt wholesale
                  generators or affiliated power marketers shall operate
                  independently of one another. AEP shall document all employee
                  movement between and among all affiliates. Such information
                  shall be made available to each State Commission and consumer
                  advocate upon request.

         H.       An AEP operating company may not own property in common with
                  an affiliated exempt wholesale generator or affiliated power
                  marketer.

         I.       No market information obtained in the conduct of utility
                  business may be shared with an affiliated exempt wholesale
                  generator or affiliated power marketer, except where such
                  information has been publicly disseminated or simultaneously
                  shared with and made available to all non-affiliated entities
                  who have requested such information. Customer-specific
                  information shall not be made available to an affiliated
                  exempt wholesale generator or affiliated power marketer except
                  under the same terms as such information would be made
                  available to a non-affiliated company, and only with the
                  written consent of the customer specifying the information to
                  be released.

         J.       A non-utility affiliate may use an AEP operating company's
                  name or logo only if, in connection with such use, the
                  affiliate makes adequate disclosures to the effect that (i)
                  the two entities are separate, (ii) it is not necessary to
                  purchase the non-regulated product or service to obtain
                  service from the operating company; and (iii) the customer
                  will gain no advantage from the operating company by buying
                  from the affiliate.

         K.       An AEP operating company shall not condition or tie the
                  provision of any product, service, pricing benefit or waiver
                  of associated terms or conditions to the purchase of any good
                  or service from its affiliated exempt wholesale generator or
                  power marketer.

         L.       Except as provided in paragraph M, an affiliated exempt
                  wholesale generator or affiliated power marketer shall not
                  share office space, office equipment, computer systems or
                  information systems with an AEP operating company.


                                       8
<PAGE>   24
         M.       Computer systems and information systems may be shared between
                  an AEP operating company and non-utility affiliates only to
                  the extent necessary for the provision of corporate support
                  services; however, the operating company shall ensure that the
                  proper security access and another safeguards are in place to
                  ensure full compliance with these affiliate rules.

         N.       An AEP operating company may engage in transactions directly
                  related to the provision of corporate support services with
                  its affiliates in accordance with requirements relating to
                  service agreements. As a general principle, such provision of
                  corporate support services shall not allow or provide a means
                  for the transfer of confidential information from the
                  operating company to the affiliate, create the opportunities
                  for cross-subsidization of affiliates, or otherwise provide
                  any means to circumvent these affiliate rules.

         O.       Except as provided in paragraph N, an AEP operating company
                  may only make a product or service available to an affiliated
                  exempt wholesale generator or an affiliated power marketer if
                  the product or service is equally available to all
                  non-affiliated exempt wholesale generators and power marketers
                  on the same terms, conditions and prices, and at the same
                  time. An AEP operating company shall process all requests for
                  a product or service from affiliated and non-affiliated exempt
                  wholesale generators and power marketers on a
                  non-discriminatory basis.

         P.       An AEP operating company which provides both regulated and
                  non-regulated services or products, or an affiliate which
                  provides services or products to an AEP operating company,
                  shall maintain documentation in the form of written
                  agreements, an organization chart of AEP (depicting all
                  affiliates and AEP operating companies), accounting bulletins,
                  procedure and work order manuals or regulated and
                  non-regulated services or products. Such documentation shall
                  be available, subject to requests for confidential treatment,
                  for review by State Commission in accordance with Paragraph B
                  above.

         Q.       AEP shall designate an employee who will act as a contact for
                  State Commissions and consumer advocates seeking data and
                  information regarding affiliate transactions and personnel
                  transfers. Such employee shall be responsible for providing
                  data and information requested by a State Commission for any
                  and all transactions between the jurisdictional operating
                  company and its affiliates, regardless of which affiliate(s),
                  subsidiary(ies) or associate(s) of an AEP operating company
                  from which the information is sought.

         R.       AEP shall designate an employee or agent within each signatory
                  state who will act as a contact for retail consumers regarding
                  service and reliability concerns and to allow a contact for
                  retail consumers for information, questions and assistance.
                  Such AEP representative shall be able to deal with billing,
                  maintenance and service reliability issues.

         S.       AEP shall provide each signatory state a current list of
                  employees or agents that are designated to work with each
                  State Commission and consumer advocate


                                       9
<PAGE>   25
                  concerning state regulatory matters, including, but not
                  limited to, rate cases, consumer complaints, billing and
                  retail competition issues.

         T.       Thirty (30) days prior to filing any affiliate contract
                  (including service agreements) with the SEC or the FERC an AEP
                  operating company shall submit to each affected State
                  Commission a copy of the proposed filing.

         U.       Any violation of the provisions of these affiliate standards
                  are subject to the enforcement powers and penalties at the
                  State Commissions.

         V.       AEP shall contract with an independent auditor who shall
                  conduct biennial audits for eight years after merger
                  consummation of affiliated transactions to determine
                  compliance with these affiliate standards. The results of such
                  audits shall be filed with the State Commissions. Prior to the
                  initial audit, AEP will conduct an informational meeting with
                  the State Commissions regarding how its affiliates and
                  affiliate transactions will or have changed as a result of the
                  proposed merger.

         W.       If the Public Utility Holding Company Act of 1935 is repealed
                  or materially amended during the time this Agreement is in
                  effect and equivalent jurisdiction is not given to another
                  federal agency, AEP will work with the State Commissions to
                  ensure that AEP continues to furnish the State Commission with
                  the appropriate information to regulate its jurisdictional AEP
                  operating company. The State Commission may establish its
                  reporting requirements regarding the nature of intercompany
                  transactions concerning the operating company and a
                  description of the basis upon which cost allocations and
                  transfer pricing have been established in these transactions.

9. ADEQUACY AND RELIABILITY OF RETAIL ELECTRIC SERVICE. AEP agrees to maintain
or enhance the adequacy and reliability of retail electric service provided by
each of the AEP operating companies. Service reports will be submitted to the
State Commissions participating in this Agreement in the format described in
Attachment C to this Agreement.

10. STATUTORY AND OTHER ISSUES. Provided the proposed merger is ultimately
consummated, AEP commits that upon issuance of any final and non-appealable
order from any state or federal commission addressing the merger that provides
benefits or imposes conditions on AEP that would benefit the ratepayers of any
jurisdiction, such net benefits and conditions will be extended to all other
retail customers to the extent necessary to achieve equivalent net benefits and
conditions to all retail customers of AEP.

11. CONTINUED PARTICIPATION. Nothing in this Agreement is intended to preclude
the Commission and its staff from addressing in a manner not inconsistent with
this Agreement issues raised in FERC Docket No. EC98-40-000.

12. ENFORCEABILITY. AEP and I&M will not assert in any action to enforce an
order approving this Agreement that the Commission lacks the authority to have
the provisions of this Agreement enforced under Indiana law.

                          Quality of Service Reporting



         Indiana Michigan Power will maintain the overall quality and
reliability of its electric service at levels no less than it has achieved in
the past decade.

         Indiana Michigan Power will provide service reliability reports
annually indicating its calendar year Indiana Customer Average Interruption
Duration Index (CAIDI) and Indiana System Average Interruption Frequency Index
(SAIFI). These indices shall be determined and reported, including all storms.
Definitions for these measures are included in this Attachment.

         Indiana Michigan Power also will provide annual Call Center performance
measures for those centers which handle Indiana customer calls. These will
include the Call Center Average Speed of Answer (ASA), Abandonment Rate, and
Call Blockage. Definition for these measures are included in this Attachment.

         The performance information described above shall be provided by the
end of May of the year following the calendar in question.

                            AEP Reliability Measures



1)       System Average Interruption Frequency Index (SAIFI) is defined as the
         number of customers interrupted divided by the number of customers
         served. It is calculated by the equation:

                  SAIFI = number of customers interrupted
                          -------------------------------
                           number of customers served

2)       Customer Average Interruption Duration Index (CAIDI) is defined as the
         number of customer hours of interruption divided by the number of
         customers interrupted. It is calculated by the equation:

                  CAIDI = sum of all customers hours of interruption
                          ------------------------------------------
                               number of customers interrupted

                            AEP Call Center Measures



1. Average Speed of Answer (ASA) is defined as the average time that elapses in
seconds between the instant when a call is answered and the time it is connected
to a Call Center representative (CSR) or an interactive voice recorder (IVR). It
is calculated using the equation:

<TABLE>
<S>                        <C>

CORPORATION


BY THE COMMISSION:

David E. Ziegner, Commissioner
Camie J. Swanson-Hull, Commissioner
Claudia J. Earls, Administrative Law Judge

                  On June 29, 1998, the Commission on its own motion initiated
an investigation regarding the proposed merger of American Electric Power
Company, Inc. ("AEP") and Central and South West Corporation ("CSW"). AEP is the
parent company of Indiana Michigan Power Company ("I&M") which provides electric
utility service in the State of Indiana. The Order noted that AEP and CSW had
filed an application with the Federal Energy Regulatory Commission ("FERC") for
approval of the merger under Section 203 of the Federal Power Act.

                  Petitions to intervene in this matter were filed by the
Citizens Action Coalition of Indiana, Inc., Indiana Consumers For Fair Utility
Rates run ad hoc group of industrial companies), PSI Energy, Inc. and Steel
Dynamics, Inc.(1) These petitions were granted and these persons were made
parties to this proceeding. The Office of Utility Consumer Counselor also
participated in this proceeding.

                  After receiving written comments of the parties on certain
issues relating to the proposed merger and after holding a preliminary hearing
on August 4, 1998, the Commission on September 2, 1998, issued an Order
appointing a negotiating team of members of the Commission Staff (the "Staff
Negotiating Team") to attempt to negotiate a settlement of the issues presented
in this matter.

                  By docket entries, I&M was directed to respond to various data
requests seeking information about the proposed merger and to provide to the
Commission, the Staff Negotiating Team and the other parties certain documents
relating thereto. I&M responded to the requests by providing the requested
information and documents.

                  During the course of this proceeding, status hearings were
held at which time the Staff Negotiating Team submitted reports regarding the
progress of negotiations. On April 9, 1999, I&M and the Staff Negotiating Team
submitted to the Commission and recommended for approval a Stipulation and
Settlement Agreement (the "Settlement

(1) SDI subsequently withdrew from the proceeding.
<PAGE>   38
Agreement") executed by I&M, AEP and the Staff Negotiating Team.

                  On April 15, 1999, the parties to the Settlement Agreement
prefiled with the Commission prepared testimony and evidence in support of the
Settlement Agreement. Pursuant to notice of hearing given as provided by law, a
public evidentiary hearing on the Settlement Agreement was held on April 19,
1999, at 10:00 a.m. in Room TC10 of the Indiana Government Center South,
Indianapolis, Indiana. At that time, the Settlement Agreement and evidence
relating thereto were accepted into the record.

                  Having considered the evidence and being duly advised, the
Commission now finds:

     1. Notice and Jurisdiction. Due legal and timely notice of the settlement
hearing was given and published as required by law. I&M is a "public utility"
within the meaning of that term in IC 8-1-2-1 and is subject to the jurisdiction
of the Commission in the manner and to the extent provided by the laws of the
State of Indiana.

     2. The Settlement Agreement. As described in the Settlement Agreement, a
copy of which is attached hereto as Exhibit A and incorporated herein by
reference, the Settlement Agreement contains, among other things, provisions
regarding (a) net non-fuel merger savings; (b) fuel and purchased power merger
savings; (c) limitation on requests for stranded cost recovery; (d) allocation
of proceeds from the sale of facilities; (e) system integration agreements; (f)
Ohio Power waiver; (g) regional transmission organization commitments; (h)
affiliate standards; and (i) maintenance and enhancement of the adequacy and
reliability of retail electric service, including certain reporting
requirements.

                  The Settlement Agreement further provides that if any other
state commission or any federal commission issues a final and non-appealable
order addressing the merger that provides benefits or imposes conditions that
would benefit ratepayers of another jurisdiction. AEP will extend equivalent net
benefits and conditions to all AEP retail customers.

                  The Settlement Agreement also provides that, upon approval by
the Commission, neither the commission nor its Staff shall oppose the proposed
merger before FERC or oppose AEP's previously made merger-related filings with
the Securities and Exchange Commission.

                  The Settlement Agreement also states that it shall not
constitute nor be cited as precedent or deemed an admission by any party in any
other proceeding except as necessary to enforce its terms before the Commission,
or any State Court of competent jurisdiction on these particular issues. The
Settlement Agreement provides that it is solely the result of compromise in the
settlement process, shall not constitute a concession of subject matter
jurisdiction, and except as expressly provided therein, is without prejudice to
and shall not constitute a waiver of any position that any of the parties
thereto may take with respect to any or all of the items resolved therein in any
future regulatory or other proceedings.

                  The Settlement Agreement states that if the Commission does
not approve the Settlement Agreement in its entirety, it shall be null and void
and deemed withdrawn, unless such change is approved by the parties.
<PAGE>   39
     At the settlement hearing, Robert C. Glazier, Director of Utilities for the
Indiana Utility Regulatory Commission, Richard E. Munczinski, Senior Vice
President-Corporate Planning and Budgeting of American Electric Power Service
Corporation, the service corporation subsidiary of AEP, and Kent D. Curry,
Director of Regulatory Affairs for I&M, testified in support of Commission
approval of the Settlement Agreement. Mr. Glazier and Mr. Munczinski discussed
the negotiating process which resulted in the Settlement Agreement and the
public benefits that would result from its approval. Mr. Curry testified
regarding the mechanism by which the bill reductions will be implemented by I&M.

     3. Commission Findings. In our Order dated June 29, 1998, the Commission
stated that this investigation was commenced because the Commission believed
that the proposed merger of AEP and CSW could have a significant impact on the
electric industry and customers in Indiana and across the region and the
Commission was concerned about the proposed merger's effect on the reliability
of service and the development of independent system operators. During the
course of this proceeding considerable information about the proposed merger was
requested from and provided by I&M. Additional information about the proposed
merger has since been developed in the course of FERC proceedings and
proceedings before other state commissions. After lengthy and detailed
negotiations. I&M, AEP and Staff Negotiating Team have reached agreement on
terms and conditions which help ensure that Indiana consumers will fairly share
in the benefits achieved by the merger and that Indiana consumers will be
protected against any detrimental effects. The Staff Negotiating Team recommends
that the Commission approve the Settlement Agreement as a fair and just
settlement of differences regarding merger-related issues. Having reviewed the
Settlement Agreement and the evidence relating thereto, the Commission finds
that the recommendation of the Staff Negotiating Team should be approved. The
Commission further finds that the Settlement Agreement is a fair and reasonable
resolution of the merger-relating issues of concern to the Commission and should
be approved in its entirety without modification.

     IT IS THEREFORE ORDERED BY THE INDIANA UTILITY REGULATORY COMMISSION THAT:

         1. The Settlement Agreement shall be and hereby is approved in its
entirety without modification.

         2. I&M shall implement the bill reductions as set forth in the
Agreement.

         3. I&M shall be and hereby is authorize to defer and amortize its
Indiana jurisdictional estimated merger-related costs-to-achieve savings over an
eight-year period, as set forth in the Agreement.

         4. The investigation in this Cause commenced by our Order dated June
29, 1998 is hereby terminated.

         5. This Order shall be effective on and after the date of its approval.

"Signatories." This Agreement addresses issues affecting the Signatories in all
jurisdictions served by the Companies. The Signatories agree as follows:

I.       Workforce

         A.       The Companies agree not to eliminate any current IBEW employee
                  as a direct result of the proposed merger between the
                  Companies. As used in this Agreement, the term "direct result
                  of the merger" shall mean the result of synergies identified
                  at the time the merger was announced.

         B.       The Companies agree that any IBEW represented employee whose
                  position is eliminated as a direct result of the sale of
                  ownership interests in the Northeast Station, Oolagah,
                  Oklahoma, will be provided with another employment opportunity
                  within the bargaining unit.

II.      Cook Negotiations

         The Signatories agree that normal negotiations will proceed to
         resolution at Cook Plant.

         facility subject to a collective bargaining agreement.

         (See Exhibit A)

IV.      Organizing Conduct

         The Signatories agree that, in the event IBEW engages in organizing
         efforts among AEP and/or CSW unrepresented employees, neither party
         shall coerce or intimidate employees during the course of an organizing
         campaign. The Companies agree to refrain from negative public
         statements concerning IBEW and any IBEW officer, representative or
         member. IBEW, its officers, representatives and employees agree not to
         publicly express negative comments concerning the Companies' integrity
         or motives including the integrity or motives of the Companies'
         officers, directors, agents or employees. The Signatories agree that
         all oral or written statements made during the course of an organizing
         campaign shall be factual.

         their merger, include in all IBEW contracts an "Agency Shop" provision
         covering employees hired after the effective date of the merger. The
         Companies will also, at the same time, include "Maintenance of
         Membership" language in all IBEW contracts. Such provision will cover
         all employees hired prior to the merger who are or become members of
         their respective local IBEW unions. The Companies also agree to a dues
         checkoff provision that shall be irrevocable by the employee for

                  Labor Relations Board.

         C.       The Companies will reimburse IBEW up to $73,000 for costs
