Dear Mr. Boergers:

            Pursuant to section 203 of the Federal Power Act ("FPA"), 16
U.S.C. section 824b (1994 and Supp. 1997), and Part 33 of the Commission's
regulations, 18 C.F.R. Part 33 (2000), The AES Corporation ("AES") and
IPALCO Enterprises, Inc. ("IPALCO") on behalf of their respective
FPA-jurisdictional subsidiaries (collectively, "Applicants") hereby apply
for all approvals necessary to consummate AES's acquisition of IPALCO.
Applicants respectfully request that the Commission approve the proposed

                         Confidentiality Agreement

This Confidentiality Agreement is dated __________________

WHEREAS PA Consulting Group ("PA") has developed the Competitive Analysis
Screening model ("CASm") for the specific purpose of performing analyses
related to Appendix A of the FERC Merger Policy Statement, Order No. 592;

WHEREAS CASm is confidential and valuable proprietary property of PA, and
is considered to be a trade secret; WHEREAS in connection with the
application of The AES Corporation and IPALCO Enterprises, Inc.
("Applicants") (before the Federal Energy Regulatory Commission, Docket No.
EC01-__-000) (the "Application"), ____________________________ requires
disclosure of CASm (the "Confidential Information") to certain of its staff
and to outside technical experts (collectively, the "Recipients"), and
agrees that such disclosure will be subject to the terms and conditions set
forth in this Confidentiality Agreement; and

WHEREAS, in consideration of the disclosure of CASm, the undersigned
Recipient is willing to keep the Confidential Information confidential in
accordance with the terms and conditions set forth in this Agreement.
NOW, THEREFORE, PA and the undersigned Recipient hereby agree as follows:

1.  CONFIDENTIALITY. The Recipient agrees to hold CASm in strict
    confidence, not to disclose, distribute or disseminate it in any way to
    any third party who has not already signed a copy of this Agreement,
    and not to use CASm for its own benefit or the benefit of others,
    except in connection with the consideration of the Application as
    expressly authorized in this Agreement. This Agreement does not extend
    to the results of runs performed by Recipient using CASm. In order to
    comply with this obligation, the Recipient further agrees to make only
    two copies of CASm, and to restrict the access to CASm to only those
    persons who have a need to know and who specifically agree in writing
    to the terms of this Agreement. The obligations set forth herein do not
    apply to information which is (1) publicly known or becomes publicly
    known through no fault or unauthorized act of the Recipient, (2)
    received from a third party not bound to secrecy to PA, or (3)
    independently developed by the Recipient without use of PA's
    proprietary property so long as such independent development can be
    clearly documented and verified.

2.  RETURN OF CASM. Upon completion of its review of the Application, the
    Recipient agrees to return all copies of CASm it received or made, and
    any and all derivatives thereof, to PA. Nothing in this Agreement shall
    require the Recipient to return to PA any of the runs performed by
    Recipient using CASm.

3.  NO FURTHER RIGHTS. Nothing contained in this Agreement shall be construed
    as granting or conferring any rights by license or otherwise in CASm,
    except as expressly provided herein.

4.  INJUNCTIVE RELIEF. The Recipient acknowledges and agrees that CASm is the
    confidential, proprietary property of PA, and that the unauthorized use
    or disclosure of CASm could cause irreparable harm and significant
    injury to PA for which PA would have no adequate remedy at law.
    Therefore, PA shall have the right, in addition to any other rights PA
    may have at law or in equity, to seek immediate injunctive relief
    enjoining any breach or potential breach of this Agreement by the
    Recipient. The Recipient hereby waives the necessity of posting any
    form of bond relating to the issuance of injunctive relief.

5.  NO MODIFICATIONS. This Agreement may only be modified by a written
    document executed by authorized representatives of the parties.

6.  OTHER AGREEMENTS. Nothing in this Agreement provides for the disclosure
    of information that Applicants contend is privileged and confidential.
    To the extent that the disclosure of CASm-related data files includes
    the disclosure of Applicants' privileged or confidential information,
    the Recipients must obtain all necessary approvals for the disclosure
    of such information from the Applicants prior to PA's disclosure of
    CASm-related data files.

                    JOINT APPLICATION FOR AUTHORIZATION
                 UNDER SECTION 203 OF THE FEDERAL POWER ACT
                FOR DISPOSITION OF JURISDICTIONAL FACILITIES

            Pursuant to section 203 of the Federal Power Act ("FPA"), 16
U.S.C. section 824b (1994 and Supp. 1997), and Part 33 of the Commission's
regulations, 18 C.F.R. Part 33 (2000), The AES Corporation ("AES") and
IPALCO Enterprises, Inc. ("IPALCO") on behalf of their respective
FPA-jurisdictional subsidiaries (collectively, "Applicants") hereby apply
for all approvals necessary to consummate AES's acquisition of IPALCO.(1)

Applicants respectfully request that the Commission approve the proposed
transaction by February 15, 2001.

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

(1)  Each Applicant owns one traditional utility subsidiary; AES owns Central
     Illinois Light Company ("CILCO") and IPALCO owns Indianapolis Power & Light
     Company ("IPL"). In addition, as described in Section II, both Appli cants
     own entities authorized by the Commission to make wholesale sales of power
     at market-based rates.


I.    INTRODUCTION

            IPALCO and AES have agreed to a share exchange under which
IPALCO will become a wholly-owned subsidiary of AES. Under the agreement,
each outstanding share of IPALCO's common stock will be converted into the
right to receive shares of AES common stock with a market value of $25.00
per share (subject to adjustment as described below). As a result of this
transaction, IPALCO's and AES's traditional public utility subsidiaries,
CILCO and IPL, will become affiliated. A description of the Applicants is
set forth in Section II below, and a more detailed description of the
transaction is set forth in Section III below.

            The Commission considers three factors in evaluating proposed
mergers and other dispositions under FPA section 203: the proposed
transaction's effect on (i) competition, (ii) rates and (iii) regulation.(2)
As detailed in Section IV below, the proposed transaction easily satisfies
the Commission's section 203 review criteria, and the Commission should
find that the transaction is in the public interest.

            The affidavit of William H. Hieronymus, attached as Attachment
1, demonstrates that the transaction will have no adverse effect on
competition in any relevant market. Dr. Hieronymus found that in every
destination market studied, the transaction did not result in any violation
of the thresholds used by the Commission to determine whether further
analysis is necessary. Similarly, Dr. Hieronymus concluded that the
transaction will have no adverse effect on vertical market power related to
control over transmission facilities.(3) Dr. Hieronymus also determined that
no other vertical market power concerns are present. The transaction also
will have no adverse effect on rates because IPL's only wholesale
requirements customer, Wabash Valley Power Association ("Wabash"), and
CILCO's only wholesale requirements customer, the Village of Riverton,
Illinois ("Riverton"), are subject to fixed rate contracts. Regarding
transmission rates, Applicants are committing to not seek to include in
their respective transmission revenue requirements any transaction-related
transmission costs that are not fully offset by transaction-related
transmission savings.

            Finally, the transaction will not lead to the formation of a
registered public utility holding company and, consequently, will not alter
the effectiveness of state or federal regulation over Applicants. IPL and
CILCO will continue to be subject to the same state and FERC jurisdiction
as they are now. For the foregoingreasons, and as further explained below,
the transaction is in the public interest and should be approved
expeditiously without a formal hearing.(4)

     Act; Policy Statement, Order No. 592, 61 Fed. Reg. 68,595 (Dec. 30, 1996),
     III FERC Stats. & Regs. paragraph 31,044 (1996), recons. denied, 79 FERC
     paragraph 61,321 (1997) (codified at 18 C.F.R. section 2.26) ("Merger
     Policy Statement").

(3)  As discussed below in Section IV.A.2, CILCO is a member of the Midwest
     Independent System Operator ("MISO"), and AES commits that IPL, as an AES
     subsidiary, will join a Regional Transmission Organization ("RTO") as a
     condition of the transaction if necessary to avoid an evidentiary hearing.

(4)  In support of their request, Applicants are submitting this Application,
     including the statements and exhibits required under Part 33 of the Commis
     sion's regulations, and the direct testimony and work papers of Dr.
     Hieronymus of PA Consulting Group ("PA"), supporting Applicants' Appen dix
     A screen analysis. Applicants also are submitting electronically the data
     required by Appendix B of the Merger Policy Statement. The data inputs used
     in Dr. Hieronymus' testimony and his supporting work papers are contained
     in a CD-ROM format enclosed with this Joint Application. Parties desiring
     to receive a copy of this CD-ROM should contact counsel for Applicants. A
     second CD-ROM containing PA's CASm model, which is proprietary, is being
     filed with the Commission pursuant to 18 C.F.R. section 388.112. Applicants
     request privileged treatment for this second CD-ROM. Intervenors in this
     proceeding may obtain a copy of the CASm model after entering into a
     confidentiality agreement with PA, which is attached to the transmittal
     letter accompanying this filing.


II.   DESCRIPTION OF APPLICANTS

      A.    AES

            AES, a Delaware corporation, is a public utility holding
company exempt from registration under the Public Utility Holding Company
Act of 1935 ("PUHCA") by reason of Section 3(a)(5) of PUHCA.(5) AES is a
United States-based multinational electric power generation and
distribution company with operations in 20 countries worldwide. It is
engaged principally in the development, ownership and operation of electric
generating plants and electric distribution companies, and owns or operates
more than 49,000 MW of electric generation world-wide. A description
of AES's domestic generation facilities and power marketing activities is
set forth in Attachment 2. Other activities include the sale of steam and
other commodities related to the company's generation operations, as well
as operating, construction and project development services and gas and
power marketing.

     leveraged lease. The lease expires in 2015. CLM is a wholly-owned subsid
     iary of CILCORP Investment Inc. ("CIM"), which, in turn, is a wholly-owned
     subsidiary of CILCORP Inc. CLM has no involvement in the operation of
     Springerville Unit 1; (2) Energy Investors Fund, L.P. CIM Energy Invest
     ments Inc., a wholly-owned subsidiary of CIM, owns a 3.13% limited
     partnership interest in Energy Investors Fund, L.P. (the "Fund"). The Fund
     holds interests in 18 independent power projects. CIM Energy, as a limited
     partner, has no operating control of the Fund or of the Fund's investments.
     All of these interests are passive investments.

(7)  Central Illinois Light Co. and The AES Corporation, 87 FERC paragraph
     61,293 (1999).



            CILCO provides retail electric service to approximately 193,000
customers in central and east central Illinois and provides retail gas
service to approximately 202,000 customers in central and east central
Illinois. CILCO distributes electricity in Peoria, Pekin and Lincoln,
Illinois, and provides natural gas distribution service in Peoria, Pekin
and Springfield, Illinois and numerous other communities in central and
east central Illinois. CILCO's natural gas service is exempt from the
Commission's jurisdiction under the Hinshaw Amendment to the Natural Gas
Act. The Illinois Commerce Commission ("ICC") has jurisdiction over the
rates, terms and conditions of the retail electric and gas service provided
by CILCO. CILCO also provides wholesale electric sales service pursuant to
cost- based(8) and market-based(9) tariffs on file with the Commission.(10)

            CILCO owns about 1,210 MW of generation. CILCO owns
approximately 350 miles of 345-kV, 138-kV and 34.5-kV lines which are
functionalized as transmission facilities. CILCO is part of the
Mid-American Interconnected Network ("MAIN") and is a member of the Midwest
Independent Transmission System Operator, Inc. ("MISO").

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

(8)  CILCO's cost-based tariff was approved by the Commission's unpublished
     letter order issued April 25, 1995, in Docket No. ER95-602-000.

(9)  CILCO's market-based tariff was approved by the Commission's order in
     Docket No. ER98-2440-000 issued on June 2, 1998. Central Illinois Light
     Co., 83 FERC paragraph 61,252 (1998).

(10) CILCO provides full requirements sales service to one customer, the Village
     of Riverton, Illinois, pursuant to a contract approved in Docket No. ER96-
     1365-000. CILCO provides open access transmission service under a tariff
     which was approved by the Commission in Docket Nos. OA96-36-000 and
     OA97-612-000.


      B.    IPALCO

            IPALCO, an Indiana corporation, is a public utility holding
company exempt from registration under PUHCA by reason of Section 3(a)(1)
of that Act. IPALCO has two principal wholly-owned subsidiaries, IPL and
Mid-America Capital Resources, Inc.

            IPL operates as an integrated electric utility primarily
engaged in the generation, transmission and distribution of reliable and
economical electric power to more than 430,000 retail customers in
metropolitan Indianapolis and portions of other central Indiana communities
in surrounding counties. IPL owns three primarily coal-fired electric
generating stations with total net generating capacity of 2,957 MW, one
gas-fired peaking plant with a net generating capability of 79 MW, and one
steam generating plant with a net generating capability of 19 MW.(11) IPL's
electric transmission system consists of 345 kV, 138 kV and 34.5 kV lines
designed and constructed to transfer IPL's generation to serve retail load.
A map of IPL's transmission system is attached as Exhibit I. IPL's open
access transmission tariff has been accepted for filing by FERC.(12) IPL
operates its transmission system as a control area within the East Central
Area Reliability Council, and is a party to ECAR's Inadvertent Settlement
Tariff.(13) IPL engages in transactions in wholesale markets for the purposes
of maintaining overall system reliability and minimizing the cost of
electric service to its own retail customers. IPL has received FERC
authorization to make wholesale sales of electric energy at market-based
rates.(14) IPL also owns and operates a district steam service system in
downtown Indianapolis, which, in addition to IPL's steam generating plant,
IPL has contracted to sell to Citizens.

            Mid-America Capital Resources, Inc., the holding company for
IPALCO's unregulated subsidiaries, was created in April 1984. After a
two-year venture in cablevision, Mid-America launched district cooling
systems which provide chilled water for air-conditioning services in
Indianapolis and Cleveland. A Mid-America subsidiary also produces and
distributes steam in Cleveland. Mid- America owns no electric generation or
transmission facilities, and is not engaged in the electric energy
business.

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

(11) The steam generating plant is the Perry K Steam Plant, which is being sold
     to the Board of Directors for Utilities of the Department of Public
     Utilities of the City of Indianapolis, as trustee of public charitable
     trust, d/b/a Citizens Gas & Coke Utility ("Citizens"). The Commission
     approved IPL's transfer of jurisdictional facilities to Citizens by order
     issued September 26, 2000. Indianapolis Power & Light Co., 92 FERC
     paragraph 62,257 (2000). Upon consum mation of IPL's sale of Perry K to
     Citizens, IPL will purchase the generation under a five-year contract. The
     Perry K generation is included in Dr. Hieronymus' analysis as an IPL
     facility.

(12) Indianapolis Power & Light Co., 90 FERC paragraph 61,180 (2000), settlement
     approved, 92 FERC paragraph 61,236 (2000).

(13) East Central Area Reliability Council, 91 FERC paragraph 61,197 (2000).

III.  DESCRIPTION OF THE PROPOSED TRANSACTION

            On July 15, 2000, IPALCO and AES entered into an Agreement and
Plan of Share Exchange (the "Share Exchange Agreement") whereby AES will
acquire IPALCO for $25.00 per share in a stock-for-stock transaction valued
at approximately $2.15 billion plus the assumption of approximately $890
million of debt and preferred stock. As a result of the transaction, IPL
will become affiliated with AES's public utility subsidiaries, including
CILCO.(15)
            Under the terms of the Share Exchange Agreement, upon closing,
each share of IPALCO common stock will be exchanged for a number of AES
shares such that IPALCO shareholders will receive a fixed value of $25.00
per IPALCO share, subject to adjustment as described below. The final
exchange ratio will be determined five business days prior to closing,
based upon the average daily closing prices of AES common stock for the
preceding twenty trading days, and is capped at 0.794 AES shares per IPALCO
share, subject to adjustment as described below. If the effective price at
the closing per IPALCO share would be less than $21, IPALCO has the right
to terminate the transaction. The transaction is expected to be tax free
to IPALCO shareholders. Upon closing, IPALCO will become a wholly-owned
subsidiary of AES with its headquarters remaining in Indianapolis.

            The transaction is subject to certain conditions, including
receipt of the approval of IPALCO shareholders and receipt of the
regulatory approval of the Commission and the Securities and Exchange
Commission ("SEC"),(16) and expiration or termination of the applicable
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
1976 (as amended). AES also must obtain a certification from the Indiana
Utility Regulatory Commission pursuant to Section 33 of PUHCA relating to
its investments in foreign utility companies.(17) The parties anticipate
receiving regulatory approvals and closing the transaction by early 2001.
If the closing of the transaction is delayed beyond March 31, 2001, because
of delay in receiving SEC regulatory approvals, and all other conditions
are satisfied, the $25.00 purchase price per IPALCO share will be increased
by $0.15 plus a daily increase equal to $0.375 per calendar quarter.

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

(15) IPALCO shareholders voted on October 20, 2000 in favor of this transaction.

(16) AES also has committed, if required by the SEC as a condition to issuance
     of the requisite orders, to enter into an agreement with an unaffiliated
     person within three years of completion of the transaction to divest all
     assets of CILCO subject to SEC jurisdiction. See The AES Corporation, Form
     U-1 Application, SEC File No. 70-9779, filed Oct. 27, 2000, at 3, 12.

(17) The Indiana Utility Regulatory Commission provided this certification by
     letter dated September 28, 2000.


IV.   THE PROPOSED TRANSACTION IS CONSISTENT WITH THE PUBLIC INTEREST

            The Commission's Merger Policy Statement provides that it will
consider the effects of potential mergers on competition, rates, and
regulation.

      A.    THE TRANSACTION WILL HAVE NO ADVERSE EFFECT ON COMPETITION

            As summarized below and explained fully in Dr. Hieronymus'
testimony, the analysis demonstrates that the proposed transaction will
have no adverse effect on competition. In reaching this conclusion, Dr.
Hieronymus applied the thresholds adopted by the antitrust agencies and
FERC. If these thresholds are not exceeded, it is generally concluded that
the transaction will not adversely impact competition and that no further
review of the transaction is necessary. Here, Dr. Hieronymus found no
violation of the thresholds in any market or time period. To test the
robustness of this result, Dr. Hieronymus conducted a number of
sensitivities and found that the results basically are unchanged,
suggesting that the conclusions are valid under different assumptions
regarding data inputs and market structure.

            Dr. Hieronymus analyzed the competitive effects of the proposed
transaction by following the approach outlined by FERC in the Merger Policy
Statement and Appendix A. There, the Commission stated that it has adopted
the Department of Justice/Federal Trade Commission ("DOJ/FTC") Horizontal
Acquisition Guidelines ("Guidelines") as the appropriate analytical
framework for evaluating the effects of an acquisition on competition. Dr.
Hieronymus, therefore, also has drawn on his understanding of the
Guidelines in performing his analysis. Dr. Hieronymus utilized PA's
Competitive Analysis Screening model ("CASm") to perform his analysis,
which implements the delivered price test and other calculations required
in Appendix A.

            The primary focus of Dr. Hieronymus' testimony is the potential
horizontal market power effects arising from the combination of Applicants'
electric generating assets. He examines whether the transaction could
result in creating or enhancing Applicants' ability to increase prices in
the electricity market. Dr. Hieronymus also evaluated potential vertical
market power concerns between the electric generation and transmission
stages of production.

            1.    HORIZONTAL MARKET POWER

                  a.    PRODUCT MARKETS AND TIME PERIODS

            The first step in the Commission's analysis is to identify one
or more products sold by the combining entities. Consistent with prior
cases and Commission policies, Dr. Hieronymus concluded that the product
markets relevant to the analysis of competition in this case included a
single market for non-firm energy and short term capacity, which was
evaluated with respect to economic capacity and available economic capacity
over a broad range of prices. Dr. Hieronymus concluded that long-term
capacity need not be analyzed as a separate product, because he finds no
barriers to entry in the long-term capacity market and that Applicants
could not erect any barriers to such entry.

            Dr. Hieronymus examined 11 time periods for both the economic
capacity and available economic capacity measures; the periods were
selected to reflect a broad range of system conditions. These time periods
include: three summer super-peak periods, super-peak periods for the winter
and shoulder seasons, and on-peak and off-peak periods for the summer,
winter and shoulder seasons. Each of these markets is distinguished based
upon season and market price. Dr. Hieronymus evaluated conditions assuming
destination market prices ranging from $15/MWh in the winter and shoulder
off-peak periods to $100/MWh in the summer highest peak period. This broad
range of prices and time periods should be reflective of a sufficient range
of system conditions, thus capturing a full picture of the transaction's
effect on competition.

                  b.    DESTINATION MARKETS

            To examine geographic markets, the Commission traditionally has
focused on those electric customers that are directly connected to
Applicants (or the utility system where Applicants' generating resources
are located). Each utility (or grouping of utilities in a holding company
or regional transmission organization with "non-pancaked" transmission
rates) that is directly interconnected to Applicants' system is considered
a separate "destination market" for which pre- and post- transaction market
concentration levels are computed. Additionally, the Commission has
indicated that indirectly connected utilities who historically (within two
years)have been customers of Applicants also are potential "destination
markets." Merger Policy Statement at 30,130.

            Dr. Hieronymus analyzed ten destination markets that
potentially could be affected by the transaction: CILCO (including
CILCO-TDU); Ameren, Commonwealth Edison ("ComEd"), Illinois Power ("IP")
and Springfield, Illinois City Water Power & Light ("CWLP") (all of which
are first-tier utilities of CILCO); IPL (including IPL-TDU); and American
Electric Power ("AEP"), Cinergy, Hoosier Energy Rural Electric Cooperative
("Hoosier") and Southern Indiana Gas & Electric ("SIGE"). The two other
utilities with which IPL is interconnected, Indiana Municipal Power Agency
("IMPA"), and Wabash Valley Power Association ("Wabash"), were included as
part of the Cinergy-TDU node. Based on a review of Applicants' sales during
1998 and 1999, Dr. Hieronymus found no other potential destination markets
in which Applicants made more than de minimis sales.

                  c.    RESULTS OF HORIZONTAL ANALYSIS

                           (1) ECONOMIC CAPACITY

            Dr. Hieronymus analyzed the competitive impact of combining the
generation resources (owned or controlled) of AES/CILCO and IPL. Again,
CILCO owns about 1,210 MW of generation and IPL owns about 3,055 MW of
generation. Dr. Hieronymus also attributed to Applicants any generation
purchased pursuant to long-term contract. Also included in Dr. Hieronymus'
analysis is about 4,500 MW of additional capacity owned by AES either in
operation or planned to be operating within the next few years in the
Eastern Interconnection. Nearly all that capacity is located in New
England, New York, PJM, California, Ontario and SPP and is too remote from
the relevant markets in this instance to be a significant factor in the
market power analysis. As noted in Attachment 2, most of the output from
these AES units is committed to third parties under long-term contracts.
However, as a conservative assumption, Dr. Hieronymus has attributed all of
the capacity from these units to AES in his analysis. This conservative
treatment was done principally to avoid the Commission having to review the
specific long-term contracts.

            CILCO is modeled as a member of the MISO. Dr. Hieronymus
modeled the competitive impacts of the merger under several different
assumptions regarding IPL's RTO membership. In the base case (Exhibit
WHH-2), IPL is assumed not to be a member of any RTO. Dr. Hieronymus
evaluated the impact of IPL joining the MISO or the Alliance RTO in two
ways. First, he assumed IPL was a member of the relevant RTO based on
existing RTO membership lists. See Exhibits WHH-4 (IPL joining MISO) and
WHH-5 (IPL joining Alliance). Second, Dr. Hieronymus performed the same
analysis, except that he assumed that Illinois Power and Commonwealth
Edison switched from the MISO to the Alliance RTO. See Exhibits WHH-5 (IPL
joining MISO) and WHH-6 (IPL joining Alliance).(18)

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

(18) Illinois Power and Commonwealth Edison recently announced their intention
     to switch to the Alliance RTO. Dr. Hieronymus explains that he did not
     include Ameren as a member of the Alliance RTO, despite its recently-
     announced intention to join the Alliance RTO, because the resulting RTO
     configuration would not appear to be sustainable. While the final RTO
     configurations in the region are unclear at this time, Dr. Hieronymus
     believes that the sensitivity analyses he conducted provide indicators of
     the impact of the transaction under a broad range of alternative RTO
     configurations.

            The results for the base case analysis (IPL not a member of an
RTO), show that the largest HHI changes are 14 in the concentrated CILCO
market and 11 in the concentrated IPL market. These HHI changes are well
below the safe-harbor threshold of 50. The impact of the transaction on
other destination markets is de minimis in all time periods studied; the
highest HHI change is 4.

            Dr. Hieronymus explains that these results are not surprising
given the relatively small size of the Applicants and their historical lack
of interaction. CILCO owns or controls 1,210 MW, while there are about
58,000 MW in the MAIN NERC region. IPALCO owns 3,055 MW, while there are
about 110,000 MW in the ECAR NERC region. Thus, the combined company will
own less than three percent of the combined capacity of the two NERC
regions (ECAR and MAIN) to which they belong.

            As described above, Dr. Hieronymus conducted four RTO
sensitivity analyses and found that these differing RTO assumptions did not
significantly change the results of his base case analysis. See Exhibits
WHH-4, 5, 6, and 7.

            Dr. Hieronymus also performed transmission sensitivity analyses
to test his results. First, he assumed zero transmission rates, which shows
the effects of market enlargement. Second, he assumed that full TTCs,
rather than ATCs, were available to interconnect markets. In both
scenarios, he found that the proposed transaction raised no competitive
concerns. See Exhibits WHH-16 and 17.

                        (2)   AVAILABLE ECONOMIC CAPACITY

            Dr. Hieronymus also analyzed the effects of the transaction on
competition using the available economic capacity measure. The only
difference between the economic capacity measure and available economic
capacity measure is that the latter accounts for retained load obligations.
Dr. Hieronymus believes that the available economic capacity measure is
losing its usefulness and, at least in the case of this transaction, an
analysis requires speculative and potentially contentious assumptions
concerning, inter alia, the pace of elimination of retail native load
obligations for utilities throughout the affected regions.(19) Noting the
Commission's concerns about the use of hypothetical assumptions regarding
the extent of retail access,(20) Dr. Hieronymus assumes that each utility
retains its full, historic load responsibility. The results of this
analysis, set forth in Exhibit WHH-3, show that all of the indicators are
well below the Commission's safe harbor levels.

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

(19) The Commission has stated that it has "not concluded that available
     economic capacity is a superior measure upon which to base our merger
     review deci sions" and, rather, has based its analysis on economic
     capacity. Ohio Edison Co., 81 FERC paragraph 61,110, at 61,405 (1997).

(20) See EME Homer City Generation, L.P., 86 FERC paragraph 61,016 (1999).

                        (3)   TOTAL CAPACITY

            Dr. Hieronymus also conducted an analysis using the total
capacity measure, which is the total capacity owned or controlled by a
supplier.(21) Under the total capacity measure, capacity owned by a supplier
that is committed under long- term contracts is subtracted from the amount
of capacity owned by a supplier.(22) Dr. Hieronymus explains that the
Commission's traditional hub-and-spoke methodology could not be used
directly in this instance because neither CILCO or IPL would qualify as
being in common markets, given the transmission network around Applicants.
He constructed the narrowest possible geographic market by including CILCO,
IPL and their directly interconnected utilities. The results of this
analysis, set forth in Exhibit WHH-18, show that Applicants' combined
market share is about five percent and the change in market concentration
(using the HHI indicator) is 9, which is well below the Commission's safe
harbor levels.

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

(21) The Commission has stated that the total capacity measure, while providing
     a sense of the overall size of a supplier in a market, "does not account
     for native load obligations and does not capture the availability or cost
     of genera tion, and thus is not useful for a delivered price test
     analysis." Merger Policy Statement at 30,132.

(22) As discussed above, throughout his analysis, Dr. Hieronymus did not
     subtract capacity sold by Applicants under long-term contracts from
     Applicants' owned capacity. This is a conservative assumption because it
     results in Applicants being attributed capacity which they do not control.

                        (4)   UNCOMMITTED CAPACITY

            Uncommited capacity is the amount of capacity owned or
controlled by a supplier minus the capacity that is committed to serve
native load and firm contractual obligations. Merger Policy Statement at
30,132. Dr. Hieronymus concludes that the proposed transaction raises no
competitive issues regarding uncommitted capacity because neither CILCO nor
IPL has uncommitted capacity, even assuming conservative reserve margins.
See Exhibit WHH-19. Dr. Hieronymus notes that the uncommitted capacity
measure, which is developed by subtracting a utility's native load
obligation, may not be a reliable indicator in cases, as here,(23) where
retail restructuring may reduce or eliminate a utility's native load
obligation.(24)

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

(23) CILCO's service territory, located in Illinois, is undergoing retail
     restructuring.

(24) See EME Homer City Generation, L.P., 86 FERC paragraph 61,016, at 61,039
     (1999).

            2.    VERTICAL MARKET POWER

            Dr. Hieronymus concludes that this transaction does not raise
any significant vertical market power concerns. First, regarding control
over transmission, AES's only transmission-owning company, CILCO, is a
member of the FERC-approved MISO, which is scheduled to begin operations in
November 2001. CILCO has committed to creating an independently owned and
governed institution under the MISO to which it will turn over its retained
control area operator functions. IPALCO's transmission-owning utility, IPL,
currently is not a member of an RTO and, as explained in its Order 2000
compliance filing, has elected not to participate in an RTO at this time.
However, if necessary to avoid an evidentiary hearing, AES commits that
IPL, as an AES subsidiary, will join an RTO as a condition of the
transaction. These RTO commitments should be sufficient to extinguish any
vertical market power issues arising from control of transmission.

            Second, Dr. Hieronymus concludes that neither Applicant
controls significant fuels supplies or fuels delivery systems that could be
used to exercise market power. IPL does not own or control any fuel supply
or transportation resources that could be used to prevent entry. CILCO does
provide natural gas transportation service to electric generating
facilities, however, the units served by CILCO also are owned by CILCO and
do not confer any additional ability for CILCO to exercise market power.
See Exhibit WHH-10. Dr. Hieronymus concludes that CILCO's natural gas
transportation assets do not warrant even a threshold concern regarding
vertical foreclosure.

            Third, neither Applicant possesses a monopoly over potential
generation sites that would impact the Commission's prior finding that the
long-term market for generation is competitive.(25) Dr. Hieronymus finds
substantial evidence that additional entry of more than 17,000 MW of
planned new generating capacity either has entered the market or is planned
to enter service by around 2001 in just ECAR and MAIN.(26)

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

(25) Order No. 888, at 31,649 n.86.

(26) In the delivered price test, Dr. Hieronymus included about 6,500 MW of
     planned generation capacity, representing only those units that are most
     likely to be installed, given milestones reached to date.



      B.    THE TRANSACTION WILL HAVE NO ADVERSE EFFECT ON RATES

            In the Merger Policy Statement, the Commission states that it
"will focus on ratepayer protection."(27) IPL has one wholesale
requirements and transmission customer, Wabash Valley Power Association.
IPL's contract with Wabash has fixed demand and energy rates during the
term of the contract and does not give IPL section 205 rights to alter
those rates. In these circumstances, the Commission has found that no
ratepayer protection mechanisms are necessary.(28) AES has no captive
customers. In its 1999 order approving the AES/CILCO merger, the Commission
found that the merger would not adversely affect (i) the rates of CILCO's
one wholesale requirement customer, Riverton, which is subject to a fixed
rate contract, (ii) the transmission rates of Corn Belt Electric
Cooperative, a transmission dependent utility of CILCO, which also is
subject to a fixed rate contract, or (iii) the rates charged by AES
affiliates owning QFs and EWGs, which AES cannot change unilaterally.(29) The
Commission should reach the same conclusion here.

            Regarding transmission rates, AES committed in its merger with
CILCO that CILCO would not seek and increase in its transmission rates or
its MISO rates for four years following the merger consummation. IPL
commits to not seek to include in its transmission revenue requirement any
transaction-related transmission costs that are not fully offset by
transaction-related transmission savings for five years following
consummation of the transaction. CILCO also commits that when the MISO
transmission tariff goes into effect, it will notify the MISO of any such
transaction-related costs not offset by transaction-related transmission
savings so that the MISO can exclude such costs from CILCO's zonal rates
and for computation of MISO average rates.

     62,161 (1999).

      C.    THE TRANSACTION WILL HAVE NO ADVERSE EFFECT ON REGULATION

            Because IPL will retain its independent corporate form, the
transaction will not result in the loss of jurisdiction over retail rates
and terms and conditions of service for the only state that regulates it,
Indiana. Similarly, IPL's wholesale sales and transmission services will
remain fully subject to this Commission's jurisdiction following the
transaction.

            The transaction also will not affect the Commission's
continuing jurisdiction over AES's power marketers or CILCO. Nor will the
transaction affect state or FERC jurisdiction over CILCO. AES will not
become a registered holding company as a result of the transaction and,
thus it will not affect the jurisdiction of the Commission to regulate
Applicants or their subsidiaries in relation to possible regulation by the
SEC.

NECESSARY TO ARRIVE AT THE PRO FORMA STATEMENTS SHOULD BE CLEARLY
IDENTIFIED.

            In the Merger NOPR, the Commission proposed to limit the
accounting data to be supplied with an application to:

            proposed accounting entries showing the effect of the
            transaction with sufficient detail to indicate the effects on
            all account balances (including amounts transferred on an
            interim basis), the effect on the income statement, and the
            effects on other relevant financial statements.

Proposed Section 33.5, IV FERC Stats. and Regs. paragraph 32,528 at 33,398.
Because the transaction will not affect either IPL's or CILCO's account
balances, Applicants request a waiver of the requirement to file accounting
entries. Applicants request that the Commission waive the filing of any other

            In its Merger NOPR, the Commission suggested that it would not
be necessary for Applicants to submit copies of their applications filed
with other regulatory agencies provided that copies of the orders in

VII.  REQUEST FOR EXPEDITED CONSIDERATION

            As discussed above, this transaction raises no significant
issues regarding competition, rates, or the effectiveness of federal or
state regulation. The Commission recognized in its Merger Policy Statement
that "as the pace of industry change increases, market participants require
greater regulatory certainty and expedition of regulatory action in order
to respond quickly to rapidly changing market conditions." III FERC Stats.

                              1. INTRODUCTION

Q.   PLEASE STATE YOUR NAME AND BUSINESS ADDRESS.

A.   My name is William H. Hieronymus. My business address is PA Consulting
     Group ("PA"), One Memorial Drive, Cambridge, Massachusetts 02142.

Q.   BY WHOM ARE YOU EMPLOYED?

A.   I am a Member of the Management Group of PA. PA is a leading
     management, systems and technology consultancy.

Q.   WHAT IS YOUR EDUCATIONAL BACKGROUND AND WORK EXPERIENCE?

A.   I received my Bachelor's degree from the University of Iowa in 1965,
     my Master's degree in economics in 1967 and a Doctoral degree in
     economics in 1969 from the University of Michigan, where I was a
     Woodrow Wilson Fellow and National Science Foundation Fellow. After
     serving in the U.S. Army, I began my consulting career. In 1973, I
     joined Charles River Associates Inc. as a specialist in antitrust
     economics. By the mid-1970s my focus was principally on the economics
     of energy and network industries. In 1978, I joined Putnam Hayes &
     Bartlett, Inc., where my consulting practice has focused almost
     exclusively on network industries, particularly electric utilities.
     Putnam, Hayes & Bartlett, Inc. merged with Hagler Bailly, Inc. in
     1998. Hagler Bailly was acquired by PA in October, 2000.

     During the past 25 years, I have completed numerous assignments for
     electric utilities; state and federal government agencies and
     regulatory bodies; energy and equipment companies; research
     organizations and trade associations; independent power producers and
     investors; international aid and lending agencies; and foreign
     governments. While I have worked on most economics-related aspects of
     the utility sector, a major theme has been public policies and their
     relation to the operation of utility companies.

     Since about 1988, the main focus of my consulting has been on electric
     utility industry restructuring, regulatory innovation and
     privatization. In that year, I began work on the restructuring and
     privatization of the electric utility industry of the United Kingdom.
     I also led a major study of the reorganization of the New Zealand
     electricity sector, focusing mainly on competition issues in the
     generating sector. Following privatization of the U.K. industry in
     1990, I continued to work in the United Kingdom and was involved in
     restructuring studies concerning the former Soviet Union, Eastern
     Europe, the European Union and specific European countries.

     In 1993, I returned to the United States, where I have worked primarily
     on utility restructuring and regulatory reform. In this context, I
     have testified before FERC and state commissions on market power
     issues concerned with several electric utility mergers (including
     convergence mergers), Regional Transmission Organization ("RTO")
     tariff filings, sale and purchase of jurisdictional assets and market
     rate applications. More generally, I have testified before state and
     federal regulatory commissions, federal and state courts and
     legislatures on numerous matters concerning the electric utility and
     other network industries. My resume is included as Exhibit No. WHH-1.


     2. PURPOSE AND DESCRIPTION OF APPLICANTS' PROPOSAL AND SUMMARY OF
                          ANALYSIS AND CONCLUSIONS

PURPOSE

Q.   WHAT IS THE PURPOSE OF YOUR TESTIMONY?

A.   I have been asked by The AES Corporation ("AES") and IPALCO
     Enterprises, Inc. ("IPALCO") (collectively, the "Applicants") to
     determine the potential competitive impact of their proposed
     transaction on electricity markets (for ease of reference, I will
     refer to the Applicants' proposed transaction as a merger). I
     performed the Competitive Analysis Screen described in Appendix A to
     the Commission's Merger Policy Statement ("Order No. 592"),(1) which in
     turn is intended to comport with the Department of Justice and Federal
     Trade Commission ("DOJ/FTC") Horizontal Merger Guidelines
     ("Guidelines"). As appropriate, my testimony also takes into
     consideration the Commission's Notice of Proposed Rulemaking ("Merger
     NOPR").(2)

APPLICANTS' MERGER PROPOSAL

Q.   PLEASE DESCRIBE THE APPLICANTS' MERGER PROPOSAL.

A.   On July 15, 2000, IPALCO and AES entered into an Agreement and Plan of
     Share Exchange (the "Share Exchange Agreement") whereby AES will
     acquire IPALCO for $25.00 per share in a stock-for-stock transaction
     valued at approximately $2.15 billion plus the assumption of $890
     million of debt and preferred stock. Upon closing, IPALCO will become
     a wholly-owned subsidiary of AES with its headquarters remaining in
     Indianapolis.
     As a result of the transaction, IPALCO's principal subsidiary,
     Indianapolis Power and Light ("IPL"), will become affiliated with AES'
     existing regulated and unregulated affiliates in the electric
     business, including AES' wholly owned subsidiary, Central Illinois
     Light Company ("CILCO").
     AES commits that IPL, as an AES subsidiary, will join an RTO as a
     condition of the transaction if the Commission deems that this is
     necessary to avoid an evidentiary hearing on this Application. However
     IPL is not otherwise committed to join any RTO at this time.

Summary of Analysis and Conclusions

Q.   PLEASE PROVIDE AN OVERVIEW OF YOUR ANALYSIS.

A.   I have analyzed the competitive impacts of combining the resources of
     AES and IPALCO. As noted, AES' principal subsidiary in the region is
     CILCO, which owns both generation (about 1,200 MW) and transmission
     assets in Illinois and is part of the Mid-American Interconnected
     Network ("MAIN") NERC region. CILCO also provides natural gas in its
     service territory in Illinois to end-users, including to some electric
     generating facilities, as discussed below. AES also has about 4,600 MW
     of generating assets either in operation or planned to be operating
     within the next few years in the Eastern Interconnection that I have
     included in the analysis. Nearly all of this capacity is remote from
     IPALCO, chiefly located in New England, New York and PJM. The majority
     of this capacity is committed under long-term contractual arrangements
     to other parties. Under the analysis procedures specified by the
     Commission in Order No. 592, capacity dedicated to third parties by
     long-term contracts is not deemed to be controlled by Applicants.
     Despite this guidance, however I have attributed all of the capacity
     from these units to AES in my analysis. This conservative treatment
     was done principally to avoid the Commission having to review specific
     contractual provisions for these units.

     IPL is a vertically integrated utility that owns approximately 3050 MW(3)
     of generation as well as transmission and distribution assets in
     Indiana. IPL is a member of the East Central Area Reliability Council
     ("ECAR"). IPL owns and controls no other generation, nor does any
     existing affiliate of it.

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

3    Of this amount, 19 MW of generation (net generating capability) is located
     at the IPL Perry K Steam Plant, which is being sold to the Board of
     Directors for Utilities of the Department of Public Utilities of the City
     of Indianapolis, as trustee of public charitable trust, d/b/a Citizens Gas
     & Coke Utility ("Citizens"). The Commission approved IPL's transfer of
     jurisdictional facilities to Citizens by order issued September 26, 2000.
     Indianapolis Power & Light Co., 92 FERC paragraph 62,257 (2000). Upon
     consummation of IPL's sale of Perry K to Citizens, IPL will purchase the
     generation under a five-year contract, declaring the Perry K generation as
     a Network Resource. The Perry K generation is included in this analysis as
     an IPL resource.



     I modeled CILCO as a member of the Midwest Independent Transmission
     System Operator, Inc. ("MISO"), which CILCO has committed to join. The
     MISO is expected to be operational in November 2001. IPL has not
     committed to join an RTO. AES commits, however, that IPL, as an AES
     subsidiary, will join an RTO as a condition of the transaction if the
     Commission deems that this is necessary to avoid an evidentiary
     hearing on this Application. I modeled the competitive impacts of the
     merger under different assumptions regarding IPL's RTO membership in
     order to evaluate the competitive impacts of each of the outcomes. For
     the base case results presented in my analysis, I assumed that IPL is
     not a member of any RTO. I also evaluated alternative analyses where I
     assumed (1) that IPL joins the MISO,(4) and (2) that IPL joins the
     Alliance RTO.(5) In both of the analyses where IPL joins an RTO, I
     conducted the analyses in two ways: First, I assumed that IPL was a
     member of the MISO or Alliance RTO both pre-and post-merger, and
     assumed the current membership in the relevant RTO.(6) In my second

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

4    As of October 17, 2000, seventeen transmission owners had signed the
     MISO agreement. They are Alliant Energy, Ameren, American Transmission
     Company (Milwaukee, WI) CILCO, Cinergy, Commonwealth Edison, Hoosier
     Energy Rural Electric Cooperative, Illinois Power, LG&E Energy,
     Madison Gas & Electric, Northwestern Wisconsin Electric, Southern
     Illinois Power Cooperative, Southern Indiana Gas & Electric, Wabash
     Valley Power Association, Wisconsin Electric Power and Wisconsin
     Public Service Corporation,, and Xcel Energy (formerly Northern States
     Power). (Source: http://www.midwestiso.org/newsroom.shtml).

5    The Alliance RTO currently consists of AEP, Consumers Energy, Detroit
     Edison, FirstEnergy, and Virginia Electric & Power.
     (http://www.alliancerto.com/PARTICIP.HTM)

6    In addition to the existing members, there have recently been
     additional proposed changes to the membership of each RTO, including
     Otter Tail Power and UtiliCorp joining the MISO and Dayton Power and
     Light and NIPSCo joining the Alliance RTO. Including the other
     utilities in each of the relevant RTOs, such as Otter Tail Power,
     would generally have the effect of reducing transmission costs for
     distant suppliers to the West and East of the relevant destination
     markets. Thus, excluding these newly announced additions is
     conservative and they are not included in either RTO for any of the
     analyses.



     analysis, I again assumed that IPL was a member of the MISO or
     Alliance RTO, but assumed that Illinois Power ("IP") and Commonwealth
     Edison ("ComEd") switch from the MISO to the Alliance RTO, as they
     have indicated their intention to do.(7) In both cases, I assumed that
     IPL's commitment was not merger related and that IPL was a member of
     the relevant RTO both before and after the merger. This analysis
     provides a direct evaluation of combining Applicants' resources absent
     changes in the market due to transmission rate changes.(8)

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

7    According to news reports published November 9, 2000, Ameren has
     announced that it plans to switch from the MISO to the Alliance RTO as
     well. I did not revise my RTO sensitivity analysis to reflect this
     most recent potential change as it may yet be followed by further
     membership changes and because it requires additional changes in the
     RTO sensitivity analysis. Specifically, if Ameren, in addition to IP
     and ComEd, became a member of the Alliance RTO, CILCO would no longer
     have any direct interconnections with other MISO members. While the
     final RTO configurations in the region are unclear at this time, the
     RTO sensitivity analysis that I did perform, along with an additional
     analysis assuming all transmission rates are zero (discussed below),
     provides indicators of the impact of the merger under a broad range of
     alternative RTO configurations.

8    I also conducted a sensitivity analysis assuming that al transmission
     rates were zero, except for incremental losses, and a sensitivity
     analysis on transmission capacity. These analyses are discussed below.




     The primary focus of my testimony is the potential horizontal market power
     effects (i.e., those arising from the combination of electric
     generating assets) of the merger. I have also evaluated potential
     vertical market power concerns arising from Applicants' control over
     transmission and their control over gas supplies and delivery systems.
     Finally, I have also evaluated Applicants' ability to raise other
     barriers to entry that might undercut the presumption that long-run
     generation markets are competitive, such as might arise from
     Applicants' control over potential generating sites.

Q.   DOES YOUR ANALYSIS INDICATE THAT THIS MERGER WILL INCREASE THE ABILITY
     OR INCENTIVE OF THE APPLICANTS TO EXERCISE MARKET POWER?

A.   No, I have found that the proposed merger will not increase
     Applicants' ability or incentive to exercise market power. I base this
     conclusion on a market power analysis that I performed, which I
     summarize below, and a more general review of the basic facts
     concerning the electricity market in the region where the companies
     operate.

     As discussed more fully below, the Commission, in Order No. 592, has
     adopted an analytic framework and related safe harbor thresholds used
     to determine whether a merger is unlikely to adversely impact
     competition. If these thresholds are met, then the Commission has
     stated that it generally will conclude that the merger will not
     adversely impact competition and that no further review is necessary
     to allow the merger to go forward. I have conducted an analysis using
     the framework adopted by the Commission to determine whether these
     thresholds are violated by the combination of AES and IPALCO. I find
     that they are not. A full description of the analysis and results is
     provided later in my testimony and in workpapers supporting this
     testimony.

Q.   PLEASE SUMMARIZE YOUR FINDINGS REGARDING HORIZONTAL MARKET POWER.

A.   Using the Commission's framework, I have found that the merger will
     not impact the ability or incentive of the combined firm to exercise
     market power. There are no instances in which the safe-harbor
     thresholds are violated. I also conducted a number of sensitivities to
     test the robustness of this result and have found that the results are
     basically unchanged, suggesting that the conclusions are valid under
     different assumptions regarding data inputs and market structure.

     This result is not surprising. These are two small utilities in a region
     characterized by much larger utilities that surround them and lie
     between them. There is substantial transmission available to move
     power within the region. Because of the size of Applicants relative to
     the amount of generation located in the region, combining them has a
     very minor effect on the structure of the power market.

Q.   PLEASE SUMMARIZE THE RESULTS OF YOUR BASE CASE ANALYSIS.

A.   Because there are no changes in the market, other than the combination
     of Applicants' shares, the merger's impact on the structure of power
     markets is simply a combination of Applicants' pre-merger market
     shares and examining how concentration in each of the relevant markets
     is affected. This analysis is generally referred to as the "2AB
     method."(9) It is essentially an analysis of a merger where there are no
     changes resulting from a merger - no transmission rate impact, no
     change in transmission for integration purposes, etc. This is the
     proper type of analysis to evaluate how concentration in each market
     changes and is consistent with standard antitrust analysis.

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

9    "2AB" refers to the change in HHI resulting from the merger of company
     a (with market share A) and Company b (with market share B). This
     formula is derived from the HHI calculation as follows:

         Applicants' pre-merger HHI = A2 + B2

         Applicants' post-merger HHI = (A+B)2 = A2 + B2 2AB

         Thus, the change in HHI resulting from the merger equals 2AB.




     Exhibit No. WHH-2 shows that Applicants' market shares, pre-and
     post-merger, in each of the destination markets for my base case
     analysis using the Economic Capacity measure. The largest HHI change
     in the CILCO market is 14 in a concentrated market (HHI over 1,800).
     This change is well below the safe-harbor thresholds (50) and is the
     result of adding about 4 MW of IPL's power to AES' power. Thus, I
     conclude that no further investigation is required for the CILCO
     market. The largest HHI change in the IPL market is 11 in a
     concentrated market, again well below the safe-harbor thresholds. It
     is the result of adding about 8 MW from AES to IPL's generation and is
     not indicative of any market power concerns. The impact of the merger
     on other destination markets is de minimis; the highest HHI change is
     4.

     The Available Economic Capacity measure also indicates that there are
     no competitive concerns from the merger. To conduct this analysis, I
     assumed all utilities retained their historical native load
     obligations and Exhibit No. WHH-3 shows the results for the same
     destination markets as were evaluated for the Economic Capacity
     measure. Again there are no screen violations in any market. The
     largest HHI change in the CILCO market is 7 in an unconcentrated
     market (HHI less than 1,000). The largest HHI change in the IPL market
     is 26 in a moderately concentrated market (HHI between 1,000 and
     1,800). In other destination markets, the change in concentration are
     again de minimis; the largest HHI change is 5.

Q.   PLEASE SUMMARIZE THE RESULTS OF YOUR ALTERNATIVE ANALYSES.

A.   I conducted additional analyses assuming different RTO membership for
     IPL and have again found no competitive concerns from the merger. As
     noted earlier, I evaluated the impact of IPL joining the MISO or
     Alliance RTOs in two ways. First, I assumed IPL was a member of the
     relevant RTO both pre- and post-merger, based on the existing RTO
     membership lists. These results are shown in Exhibit No. WHH-4 for the
     MISO and Exhibit No. WHH-5 for the Alliance RTO and are very similar
     to those described above for the base case analysis; there are no
     screen violations in any market.

     Second, I performed the same analyses as those presented in Exhibit
     Nos. WHH-4 and WHH-5, except that I assumed that Illinois Power ("IP")
     and Commonwealth Edison ("ComEd") switched from the MISO to the
     Alliance RTO, as discussed earlier. These results are shown in Exhibit
     Nos. WHH-6 and WHH-7. Again, there are no screen violations in any
     market.


Q.   ARE THESE RESULTS CONSISTENT WITH YOUR UNDERSTANDING OF THE MARKET IN
     THE REGIONS WHERE THE APPLICANTS OPERATE?

A.   Yes. As noted briefly above, the analytical finding tha the merger
     would not remove a significant competitor, and therefore not raise
     market power concerns, follows from the relatively small size of the
     Applicants in the regions where they operate and their historical lack
     of interaction. As noted earlier, AES' CILCO subsidiary owns or
     controls about 1,200 of the roughly 58,000 MW in the MAIN NERC
     region.(10) IPL owns about 3,050 MW of the roughly 110,000 MW in the
     ECAR NERC region.(11) The combined company will own less than 3 percent
     of the total capacity in each of these NERC regions.(12)

11   http://www.ecar.org/publications/GRP/00-GRP-33.pdf

12   As noted, AES does own or control additional capacity in other parts of the
     Eastern Interconnection (about 4,600 MW). This capacity is located in New
     England, New York, Ontario, PJM and SPP and is too remote from the relevant
     markets in this instance to be a significant factor in the market power
     analysis. (These units were, however, included in the delivered price test
     analysis.) In addition, most of the output from these units is committed to
     other entities under long-term contractual arrangements.



     Exhibit No. WHH-8 shows the relevant transmission networ around CILCO
     and IPL. CILCO and IPL are not major participants in each other's
     market or in common third markets, as discussed below. Indeed, my
     review of historic sales and purchase data demonstrates that CILCO
     trades primarily with other utilities in Illinois and IPL trades
     primarily with other utilities in Indiana. The paucity of longer
     distance trades likely is due to the very similar production costs
     across the region. Most of the generation is coal-based and has
     similar incremental costs.

     AES owns other generation in the U.S. besides that owned by its CILCO
     subsidiary. However, all of its other generation is located a
     significant distance from markets to this merger, principally in New
     York, New England, and California, and plays an insignificant role in
     price determination in Illinois and Indiana.

     The findings using the Commission's delivered price test are
     consistent with historical trade data, which show little overlap in
     the relevant markets. Exhibit No. WHH-9 shows the purchase and sales
     made by CILCO and IPL for the most recent two years available (1998
     and 1999).(13) As shown, CILCO sells primarily to Illinois utilities
     and IPL sells mostly to Indiana utilities. The only common customers
     of both companies are American Electric Power ("AEP"), Cinergy and
     ComEd. In each case, at least one of the companies had very minor
     sales to this customer and, when combined, these sales are a very
     small share of the purchases of these companies, supporting my
     conclusion that the combination will not eliminate a significant
     market participant.

13   Sales information is based on FERC Form 1 data.



Q.   PLEASE SUMMARIZE YOUR FINDINGS REGARDING VERTICAL MARKET POWER.

A.   The proposed merger does not raise any significant vertical market
     power issues. As noted earlier, AES' only transmission-owning company
     (CILCO) is a member of the MISO, an ISO that has been approved by the
     FERC and is currently scheduled to begin operations in November 2001.
     The combined company will lack the requisite control over CILCO's
     transmission to impede competition, even if it had the incentive to do
     so.

     IPL has not proposed to join an RTO in its Order 2000 compliance
     filing. As IPL explains in that filing, IPL cannot justify
     participation in either the MISO or Alliance RTO at this time because
     these RTO proposals present regulatory, commercial and operational
     uncertainty, and IPL's analysis indicates that its participation
     presently is not cost-justified. IPL operates its transmission system
     in accordance with Orders 888 and 889, and its open access
     transmission tariff has been accepted for filing by FERC.(2145)

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

14   Indianapolis Power & Light Co., 90 FERC paragraph 1,180, settlement
     approved, 92 FERC paragraph 61,236 (2000).


     IPL is a geographically very small utility surrounded by much larger
     utilities. IPL is an incidental transmission owner, and none of the
     larger utilities that surround IPL needs to use the IPL transmission
     system to reach any other utility. IPL's retail service territory is
     wholly surrounded by Cinergy's and both Cinergy and other utilities
     wishing to access the Cinergy system can do so without reserving
     capacity on the IPL system. Indeed, IPL's transmission system can be
     accurately described as either a high-voltage distribution system or a
     local area transmission system. Thus, any attempt by IPL to foreclose
     a supplier from markets, including specifically markets where its
     merger partner, CILCO, sells power could be easily thwarted; the
     supplier could simply use an alternative (and generally more
     straightforward) route to the market.

     While Applicants do not believe that this merger creates vertical
     issues in the absence of an RTO commitment, and I agree with that
     assessment, AES commits that IPL, as an AES subsidiary, will join an
     RTO as a condition of the transaction if the Commission deems that
     this is necessary to avoid an evidentiary hearing on this Application.

     Neither utility controls significant fuels supplies or fuels delivery
     systems that can be used to exercise market power. IPL does not own or
     control any fuel supply or transportation resources that can be used
     to prevent entry.(15) As noted earlier, CILCO does provide natural gas
     transportation service to electric generating facilities, however the
     units served by CILCO are also owned by CILCO and do not confer any
     additional ability for CILCO to exercise market power.(16) Regardless,
     the merger with IPL does not add any ability or incentive to foreclose
     gas supplies since, as demonstrated by the horizontal analysis, power
     from the CILCO area is an inconsequential share of the markets in
     which IPL competes. Moreover, as the Commission noted in its order in
     the NIPSCO-Columbia merger, gas almost never is on the margin in this
     area.(17) Hence, a hypothetical foreclosure of a small amount of
     gas-fired generation located on CILCO's system would have little, if
     any, effect on power prices received by IPL. Thus, I conclude that
     CILCO's natural gas transportation assets do not warrant even a
     threshold concern regarding vertical foreclosure.

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

15   IPALCO does own some undeveloped coal reserves. As IPL stated in its
     application for market-based rates, IPL owns the mineral rights to
     several thousand acres of land, and has leased a small portion of this
     acreage to an independent coal company for the purpose of mining at
     some future date. Application of Indianapolis Power & Light Co.,
     Docket No. ER00-1026, Exhibit J at 2 (Jan. 6, 2000).

16   These units are shown in Exhibit No. WHH-10. As shown i that Exhibit,
     CILCO only serves three facilities with natural gas transportation
     service, and it owns each of these units (Sterling Avenue (30 MW),
     Indian Trails (12 MW), and Medina Valley (36 MW)). CILCO also provides
     small amounts of gas for flame stabilization for two units whose
     primary fuel is either distillate oil or coal.

17   92 FERC paragraph 61,068 (2000)





     Finally, neither utility possesses a monopoly over potential
     generation sites that would affect the Commission's prior finding that
     the long-term market for generation is competitive.


ORGANIZATION OF TESTIMONY

Q.   HOW IS THE REMAINDER OF YOUR TESTIMONY ORGANIZED?

A.   In Section III, I outline Applicants' business operations. Section IV
     describes the economic framework used in the analysis as set out in
     the Commission's Order No. 592. A description of the methodology I
     used in conducting the analysis is included in Section V. My analysis
     of the merger's impact on competition is included in Section VI.
     Section VII contains my conclusions.


3.   DESCRIPTION OF THE PARTIES

AES

Q.   PLEASE DESCRIBE AES.

A    AES is a global power company. In the United States, AE owns
     generation assets throughout the country. Exhibit No. WHH-11 shows the
     generating units owned by AES included in the analysis, including
     planned generation. CILCO is the only subsidiary that operates in the
     region near IPL and the majority of CILCO's existing generation is
     coal-fired. AES' generation in Northeast and Southwest Power Pool
     ("SPP") is generally committed under long-term contracts and a
     description of AES' contracts is contained in an appendix to
     Applicants' Section 203 Application.

     CILCO is the only transmission-owning subsidiary of AES in the United
     States. As noted earlier, CILCO is a member of the MISO and will
     relinquish control of its transmission facilities to that
     organization.

     CILCO is interconnected to Ameren, ComEd (Exelon), IP an CWLP. It is
     not a significant transmission provider in the region, largely because
     its first-tier utilities are generally also directly connected with
     each other. These utilities can transact directly and do not have to
     rely on CILCO's facilities.

     CILCO's only wholesale requirements customer is the Village of
     Riverton, Illinois ("Riverton"). Riverton has a long-term fixed rate
     contract and, therefore, is immunized from any price effects
     hypothetically arising from this merger.

     CILCO is undergoing restructuring as part of the deregulation process
     in Illinois. At the end of 1997, the Illinois General Assembly passed
     the Customer Choice Law as part of electric restructuring in the
     state. Retail competition for large business customers (over 4 MW
     load) and for a percentage of non-residential customers began October
     1, 1999. By December 31, 2000 retail choice will be available to all
     non-residential customers. Full retail competition (including
     residential customers) will be effective by May 1, 2002.

IPALCO

Q.   PLEASE DESCRIBE IPALCO .

A.   IPL is one of the two the principal subsidiaries of IPALCO. IPL
     operates as an integrated electric utility primarily engaged in the
     generation, transmission and distribution of electric power to more
     than 430,000 retail customers in metropolitan Indianapolis and
     portions of other central Indiana communities in surrounding counties.
     Like CILCO, the majority of IPL's capacity is coal-fired, although it
     has recently developed a new gas-fired peaking facility in its own
     service territory.(18) IPL's generation assets are shown in Exhibit No.
     WHH-11. IPL also owns and operates a district steam service system in
     downtown Indianapolis, which IPL has contracted to sell to Citizens.

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

18   IPL recently participated in developing new peaking facilities
     (Georgetown units) that became operational last summer. IPL owns one
     approximately 80 MW peaker, while DTE Energy owns two similar peakers
     at the facility. I have included this capacity in my analysis.



     IPL's open access transmission tariff has been accepted for filing by
     FERC(19) and IPL operates its transmission system as a control area
     within ECAR. IPL has received FERC authorization to make wholesale
     sales of electric energy at market-based rates.(20)

     IPALCO's other principal subsidiary is Mid-America Capital Resources,
     Inc. ("Mid-America"). Mid-America is a holding company for IPALCO's
     unregulated subsidiaries, which are engaged in various business
     enterprises. Neither Mid-America nor its subsidiaries own any electric
     generation or transmission facilities, and they are not engaged in the
     electric energy business.

     IPL is interconnected principally to AEP, Cinergy, Hoosier Energy
     Rural Electric Cooperative ("Hoosier"), and SIGE.(21) As discussed
     earlier, IPL is an incidental transmission owner, and none of the
     larger utilities that surround IPL needs to use the IPL transmission
     system to reach any other utility. IPL's retail service territory is
     wholly surrounded by Cinergy's and both Cinergy and other utilities
     wishing to access the Cinergy system can do so without reserving
     capacity on the IPL system.

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

19   Indianapolis Power & Light Co., 90 FERC paragraph 61,180 (2000).

20   Id.

21   IPL also has interconnection agreements in place with Indiana
     Municipal Power Agency ("IMPA") and Wabash Valley Power Association,
     Inc. ("Wabash"), and accesses both IMPA and Wabash by way of IPL's
     interconnections with the Cinergy transmission system. IMPA jointly
     owns with Cinergy certain transmission facilities in the Cinergy
     transmission system, as does Wabash. I have modeled IMPA and Wabash as
     TDUs connected to Cinergy, largely because of the lack of OASIS
     postings on transmission capacity for these entities. This modeling
     does not significantly impact the results of my analysis.




     IPL's only wholesale requirements customer is Wabash. Wabash has a
     long-term fixed rate contract and, therefore, is protected from any
     price effects hypothetically arising from the merger.


4.   FRAMEWORK FOR THE ANALYSIS

Q.   WHAT ARE THE GENERAL MARKET POWER ISSUES RAISED BY MERGE PROPOSALS?

A.   Market power analysis of a merger proposal examines whether the merger
     would cause a material increase in the merging firms' market power or
     a significant reduction in the competitiveness of relevant markets.
     Market power is defined as the ability of a firm or group of firms to
     sustain profitably a significant increase in the price of their
     products above a competitive level.

     In merger analyses, the critical issue is the change in market
     competitiveness due to the merger. While the pre-merger
     competitiveness of markets may, as under the DOJ/FTC Guidelines,
     affect the amount of such change that is acceptable, the focus remains
     on the change in market competitiveness caused by the merger.

     This focus on the effects of the merger means that the merger analysis
     examines those business areas where the merging firms are competitors.
     In most instances, the merger will not affect competition in markets
     in which the merging firms do not compete. Analysis of the effects of
     a merger on market power in businesses in which the merging firms both
     participate is sometimes referred to as horizontal market power
     assessment. In the proposed merger of AES and IPALCO, therefore, the
     focus is properly on those markets in which both firms are actual or
     potential competitors. The analysis is intended to measure the adverse
     impact, if any, of the elimination of a competitor as a result of the
     combination.

     Vertical market effects of the merger relate to the merging firms'
     ability and incentives to use their market position over a product or
     service to affect competition in a related business or market. For
     example, vertical effects could result if the merger of two electric
     utilities created an opportunity and incentive to operate transmission
     in a manner that created market power for the generation activity of
     the merged company that did not exist previously. The Commission has
     identified market power as also arising from dominant control over
     potential generation sites or over fuels supplies and delivery
     systems. These are issues that could undercut the presumption that
     long-run generation markets are competitive.

Q.   WHAT ARE THE MAIN ELEMENTS IN DEVELOPING AN ANALYSIS OF MARKET POWER?

A.   Understanding the competitive impact of a merger require defining the
     relevant market (or markets) in which the merging firms participate.
     Participants in a relevant market include all suppliers and, in some
     instances potential suppliers, who can compete to supply the products
     produced by the merging parties and whose ability to do so diminishes
     the ability of the merging parties to increase prices. Hence,
     determining the scope of a market is fundamentally an analysis of the
     potential for competitors to respond to an attempted price increase.
     Typically, markets are defined in two dimensions: geographic and
     product. Thus, the relevant market is composed of companies that can
     supply a given product (or its close substitute) to customers in a
     given geographic area.

Q.   HOW HAS THE COMMISSION TYPICALLY EXAMINED PROPOSED MERGERS INVOLVING
     ELECTRIC UTILITIES?

A.   Historically, the Commission examined mergers by focusin on specific
     product markets and by using a "hub-and-spoke" screening test to
     evaluate whether a further examination of potential market power was
     warranted. With the issuance of Order No. 592 in December 1996, the
     Commission changed its analytic approach and adopted a "delivered
     price test." Appendix A (the "Competitive Analysis Screen") of Order
     No. 592 outlines a detailed analytic method that applicants are
     required to follow in their applications and that the Commission will
     use in screening the competitive impact of mergers. If a proposed
     merger raises no market power concerns (i.e., passes the Appendix A
     screen), the inquiry is generally complete. If a proposed merger
     raises potential market power concerns, applicants can propose
     mitigation measures at the time of application.

Q.   WHAT PRODUCTS HAS THE COMMISSION GENERALLY CONSIDERED?

A.   The Commission generally has defined the relevant produc markets to be
     long-term capacity, short-term capacity and non-firm energy. The
     Commission has used four measures to evaluate these products. These
     are Total Capacity ("TC"), Uncommitted Capacity ("UC"), Economic
     Capacity ("EC"), and Available Economic Capacity ("AEC").(22)

     The Commission has determined that long-term capacity markets are
     presumed to be competitive, unless special factors exist that limit
     the ability of new generation to be sited or receive fuel.(23)

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

22   Total Capacity refers to a supplier's total generation capacity, not
     accounting for any load obligations or the cost of the generation.
     Uncommitted Capacity is computed by subtracting load obligations from
     the supplier's Total Capacity and adjusting for long-term firm
     obligations and any required reserve margin. Economic Capacity is
     capacity from generating units whose variable costs are such that they
     can deliver energy to the relevant destination market, after paying
     all applicable transmission and ancillary service costs, at a price
     near the market's competitive price. Available Economic Capacity is
     the same as Economic Capacity, except that the supplier's lowest cost
     resources are "covered" by any load obligations of the supplier.

23   Promoting Wholesale Competition Through Open Access Non-Discriminatory
     Transmission Services by Public Utilities; Recovery of Stranded Costs
     by Public Utilities and Transmitting Utilities, Order No. 888, FERC
     Stats. & Regs. paragraph 31,036 at 31,657 (1996).




     The Commission also has considered vertical issues that might affect
     competition in the wholesale electricity market. Specifically, it has
     considered whether control over transmission by one merging entity
     might be used to increase the profits earned by its merger partner in
     selling energy. Similarly, it has considered whether control over gas
     transmission could be used to raise the prices received by a
     generation-owning merger partner.

Q.   HOW HAS THE COMMISSION ANALYZED GEOGRAPHIC MARKETS?

A.   To examine geographic markets, the Commission traditionally has
     focused on the utilities that are directly interconnected to the
     applicant companies. This "destination market" approach was continued
     in Order No. 592. Each utility that is directly interconnected to the
     applicants is considered a separate "destination market."
     Additionally, the Commission has suggested that utilities who
     historically have been customers of applicants are also potential
     "destination markets," and requires that applicants analyze the
     effects of mergers on such markets where their sales are material. If
     the Appendix A analysis shows that a company will not be able to
     exercise market power in its first-tier destination markets, it
     generally follows that the applicants will not have market power in
     more broadly defined and more geographically remote markets.

     The supply alternatives to each destination market are defined using
     the "delivered price test," which identifies suppliers that can reach
     a destination market at a cost no more than 5 percent over the
     pre-merger market price. Formally, the supply is considered economic
     if a supplier's generation can be delivered to a destination market,
     including delivery costs (which include transmission rates,
     transmission losses and ancillary services), at a cost that is within
     105 percent of the destination market price. Physical transmission
     constraints also are taken into consideration in determining the
     potential supply to the destination market. Thus, unlike the
     "hub-and-spoke" methodology, competing suppliers are no longer defined
     by bright lines. Competing suppliers are defined as those who have
     capacity (energy) that is physically and economically deliverable to
     the destination market. Their importance in the market (i.e., their
     market share) is determined by the amount of such capacity.

     This test is intended to be a conservative screen to determine whether
     further analysis of market power is necessary. The screen is the first
     step in determining whether there is a need for further investigation.
     If the screening test is not passed, leaving open the issue of whether
     the merger will create market power, applicants are invited to provide
     further information to demonstrate that the merger will not adversely
     affect competition. The Commission also invites applicants to propose
     mitigation remedies targeted to reduce potential anti-competitive
     effects to safe harbor levels. If it remains unpersuaded that the
     merger is competitively benign, the Commission will undertake a
     proceeding to determine whether unmitigated market power concerns mean
     that the merger is contrary to the public interest.

Q.   WHAT FRAMEWORK DOES THE COMMISSION USE TO DETERMINE WHETHER A MERGER
     POSES POTENTIAL MARKET POWER CONCERNS?

A.   In Order No. 592, the Commission adopted the DOJ/FTC Guidelines for
     measuring market concentration levels by the HHI. A key part of the
     Guidelines is a market power screen. To determine whether a proposed
     merger will have a significant anti-competitive impact, the DOJ and
     FTC consider the level of the HHI after the merger (the post-merger
     HHI) and the change in the HHI that results from the combination of
     the market shares of the merging entities. Markets with a post-merger
     HHI of less than 1000 are considered "unconcentrated." The DOJ and FTC
     generally consider mergers in such markets to have no anti-competitive
     impact. Markets with post-merger HHIs of 1000 to 1800 are considered
     "moderately concentrated." In those markets, mergers that result in an
     HHI change of 100 points or fewer are considered unlikely to have
     anti-competitive effects. Finally, post-merger HHIs of more than 1800
     are considered to indicate "highly concentrated" markets. The
     Guidelines suggest that in these markets, mergers that increase the
     HHI by 50 points or fewer are unlikely to have a significant
     anti-competitive impact, while mergers that increase the HHI by more
     than 100 points are considered likely to reduce market
     competitiveness. These are the screening thresholds (or "safe-harbor"
     levels) that I have used in my analysis.


5.   DESCRIPTION OF METHODOLOGY

Q.   PLEASE SUMMARIZE THE METHODOLOGY THAT YOU USED TO ANALYZE THE
     COMPETITIVE EFFECTS OF THE MERGER.

A.   I evaluated the competitive effects of the merger using the
     methodology described in Appendix A, as summarized above. I used PA
     Consulting's Competitive Analysis Screening model ("CASm")(24), which
     implements the delivered price test and other calculations required in
     Appendix A, to do the required analyses. The source and methodology
     for the data required to conduct the delivered price test in CASm are
     described in Exhibit No. WHH-12. A technical description of CASm is
     provided in Exhibit No. WHH-13. Given the number of periods,
     destination markets, and sensitivity analyses, described in detail
     below, I have evaluated about 880 separate measure/markets using the
     delivered price test. In addition, I also analyzed the Total Capacity
     and Uncommitted Capacity measures.

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

24   CASm was developed by predecessor companies, PHB and PHB-Hagler Bailly, and
     has been used in analyzing numerous mergers and power plant acquisitions in
     proceedings before the Commission.


Q.   WHAT DESTINATION MARKETS DID YOU ANALYZE?

A.   I examined 10 destination markets that could potentially be impacted
     by the merger.25

     I included the first-tier utilities of CILCO and IPL. A noted earlier,
     CILCO's first-tier utilities are Ameren, ComEd, IP, and CWLP and IPL's
     first-tier utilities are AEP, Cinergy, Hoosier, and SIGE.

     Appendix A instructs Applicants to also include as destination markets
     historical customers. Based on a review of Applicants' sales during
     1998 and 1999 reported in their respective FERC Form 1's, there are no
     markets that Applicants made more that a de minimis amount of sales to
     outside of each utilities' directly interconnected utilities.(26)

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

25   Exhibit No. WHH-14 includes a list of the entities (and corresponding
     abbreviations used in other exhibits), included in the analysis.

26   I excluded certain categories of customers as destinatio markets. First, I
     excluded power marketers, for the obvious reason that they do not comprise
     control areas. Similarly, I excluded municipals, cooperatives and TDUs
     which do not comprise a control area; instead, utility control areas that
     are destination markets are proxies for the competitive alternatives faced
     by these customers. Finally, I excluded markets where the Applicants sold
     an insignificant amount of energy (less than $100,000 for this purpose).
     For 1998, this would include Alliant (WPL), Wisconsin Electric Power, and
     IMPA. For 1999, this would also include DP&L. Note these markets are not
     between CILCO and IPL and the indicators of the merger's impact will be
     less than that shown in the markets analyzed.



Q.   DID YOU ANALYZE A DESTINATION MARKET FOR APPLICANTS' TDU CUSTOMERS?

A.   Yes. The CILCO and IPL home destination markets are reasonable proxies
     for any of Applicants' TDU customers.

Q.   WHAT TIME PERIODS DID YOU ANALYZE?

A.   For each destination market, I examined eleven time periods for both
     the Economic Capacity and Available Economic Capacity measures,
     selected to reflect a broad range of system conditions. I evaluated
     hourly load data to aggregate similar hours.(27) I defined periods
     within three seasons (Summer, Winter and Shoulder) to reflect the
     differences in unit availability and transmission capacity as well as
     base flows on the network, as reflected in ATC values.

     The periods evaluated (and the designations used to refe to these
     periods in exhibits) are:

     SUMMER (June-July-August)

     SUPER PEAK 1 (S_SP1): Top 25 load hours

     SUPER PEAK 2 (S_SP2): Next 125 load hours


     SUPER PEAK 3 (S_SP3): Next 350 load hours

     PEAK (S_P): Remaining peak hours(28)

     OFF-PEAK (S_OP): All off-peak hours

     WINTER (December-January-February)

     SUPER PEAK (W_SP): Top 150 load hours

     PEAK (W_P): Remaining peak hours

     OFF-PEAK (W_OP): All off-peak hours

     SHOULDER (March-April-May-September-October-November).

     SUPER PEAK (SH_SP): Top 150 load hours

     PEAK (SH_P): Remaining peak hours

     OFF-PEAK (SH_OP): All off-peak hours

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

27   IPL's hourly load data was used as the basis for aggregating similar hours.
     The results would not differ significantly if this aggregation was done
     using a different reference utility.

28   Peak and off-peak hours were defined based on NERC's definition, except
     that I considered only non-holiday Monday-Friday as peak days, whereas NERC
     defines the peak days as non-holiday Monday-Saturday. See
     ftp://www.nerc.com/pub/sys/all_updl/oc/opman/apdx1f.doc .


Q.   WHAT COMPETITIVE PRICE LEVELS DID YOU ANALYZE?

A.   For each destination market, I evaluated conditions assuming
     destination market prices ranging from $15/MWh in the Winter and
     Shoulder Off-Peak periods (W_OP and SH_OP) to $100/MWh in the Summer
     Super Peak 1 period (S_SP1). This broad range of prices, in
     combination with the time periods, should be reflective of a
     sufficient range of system conditions such that a full picture of the
     merger's effects is captured.

Q.   DID YOU TAKE SYSTEM LAMBDAS AND OTHER PUBLICLY AVAILABLE PRICING
     INFORMATION INTO CONSIDERATION IN CHOOSING THE PRICE LEVELS TO
     ANALYZE?

A.   Broadly yes. Exhibit No. WHH-15 shows the relevant system lambda and
     Power Markets Week information. Both sources are subject to well known
     limitations. System lambda data are subject to the vagaries of the
     source utility's methodology. For example, a number of utilities
     report a constant system lambda on a year-round basis, while other
     utilities in the region show significant differences depending on
     season. However, I did take the system lambda data into account in
     selecting the prices to analyze, particularly to identify the lower
     range of price to be analyzed.

     Reported power market prices are subject to potential sampling error;
     they represent a fairly limited number of trades in relevant regions;
     they are not necessarily consistent with all the underlying data used
     in the Appendix A analysis (e.g., in Appendix A transmission rates are
     assumed to be the maximum filed-rates, while the market prices would
     reflect actual transmission costs incurred); and there are far fewer
     pricing "hubs" for reported market data than there are destination
     markets.

     The purpose of considering varying conditions (prices, seasons and
     load levels) in Appendix A analyses is to test whether a merger that
     might be benign under particular market conditions (e.g., at peak
     load) would be less benign under other, frequently occurring,
     conditions. Thus, the key requirement is to span the full range of
     likely conditions. Ultimately, I concluded that a range of prices from
     $15 per MWh in off-peak periods to $100 in the summer super peak was
     sufficient to fully explore possible differences in expected
     competitive conditions throughout the year. The $15 price is the
     lowest typical price that can be anticipated on a non-transitory
     basis. While transactions data (and some occasional system lambda
     data) demonstrate that prices can sometimes exceed $100 per MWh,
     modeling higher prices would not change my results. At $100 per MWh,
     essentially all of the capacity of all of the market participants in
     all of the relevant markets is economic (the incremental costs even of
     inefficient peaking units is less than $105/MWh), so the supply of
     economic energy would not be different at higher prices.

Q.   PLEASE DESCRIBE THE BASIC MODEL ARCHITECTURE YOU USED IN ANALYZING
     THIS MERGER.

A.   Briefly, CASm is a linear programming model developed specifically to
     perform the calculations required in undertaking the delivered price
     test. The model includes each potential supplier as a distinct "node"
     or area that is connected via a transportation (or "pipes")
     representation of the transmission network. Each link in the network
     has its own non-simultaneous limit and cost. Potential suppliers are
     allowed to use all economically and physically feasible links or paths
     to reach the destination market. In instances where more generation
     meets the economic facet of the delivered price test than can actually
     be delivered on the transmission network, scarce transmission capacity
     is allocated based on the relative amount of economic generation that
     each party controls at a constrained interface.

     I represented simultaneous imports into a destination market based on
     a "common limiting element" approach consistent with the Commission's
     approach outlined in Ohio Edison Co.(29)

     application to form FirstEnergy Corp.).

Q.   WHAT REPRESENTATIVE YEAR DID YOUR ANALYSIS COVER?

A.   Order No. 592 requires that the analysis be forward looking. I intend
     my analysis to approximate conditions in 2001 as a representative
     near-term future year. I used control area to control area limits
     (ATCs and TTCs) from current OASIS postings to represent the transfer
     capacity between each area in the model.(30) These are the most recently
     available data. (The analysis is conducted in year 2000 dollars.)

     Where appropriate, I adjusted other relevant data to approximate 2001
     conditions. As described in Exhibit No. WHH-12, this includes load,
     generation costs and a conservative amount of confirmed new construction.

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

30   The OASIS data were retrieved during July and August and generally provide
     postings from August 2000 to August 2001. The data from each month were
     averaged to derive seasonal values in the analysis, as described in Exhibit
     No. WHH-12.

6.   IMPACT OF THE MERGER ON COMPETITION HORIZONTAL MARKET POWER

Q.   WHAT SPECIFIC ANALYSES DID YOU CONDUCT TO EVALUATE THE POTENTIAL
     EFFECTS ARISING FROM THE COMBINATION OF GENERATION ASSETS?

A.   Consistent with the guidance in Order No. 592, I analyzed Economic
     Capacity and Available Economic Capacity, focusing on the combination
     of Applicants' generation. Given the status of restructuring in
     Illinois and surrounding regions, the Economic Capacity analysis is
     the measure most relevant to this merger. As discussed infra, the
     Available Economic Capacity analyses does not provide a fully reliable
     and useful insight into future market conditions since the native load
     that distinguishes this analysis from the Economic Capacity analysis
     is changing at unpredictable rates.

     I have also analyzed Total Capacity and Uncommitted Capacity, although
     these measures are not required explicitly by Order No. 592 or the
     Merger NOPR. Under the normal application of the Commission's
     "hub-and-spoke" analysis of Total and Uncommitted Capacity Applicants'
     would not be in the same market due to their geographical
     configuration. Nevertheless, I did perform an analysis of these two
     measures including only the directly interconnected utilities of CILCO
     and IPL. This is the narrowest, feasible geographic market that can be
     defined that includes both CILCO and IPL.(31)

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

31   If the market were defined to also include AES' units in other parts of the
     Eastern Interconnection, such as New York, the resulting market shares
     would be even lower than those reported since the market would also include
     all of the other capacity located between ECAR and New York.

     ECONOMIC CAPACITY

Q.   PLEASE SUMMARIZE THE ECONOMIC CAPACITY MEASURE.

A.   My analysis of Economic Capacity shows that there are no screen
     failures in any relevant market. As noted earlier, this is principally
     due to the presence of several much larger suppliers in the
     Applicants' region that can compete in the energy market, including
     AEP, Ameren, Cinergy and ComEd, as well as other suppliers at
     approximately the scale of Applicants. It is also due to the
     relatively limited transmission capacity into and out of Applicants'
     principal electric generating companies.

     Exhibit No. WHH-2 shows that Applicants' market shares, pre- and
     post-merger, in each of the destination markets. As noted earlier, I
     assumed in my base case analysis that IPL was not a member of any RTO
     both pre- and post-merger. All of the results are less than the
     safe-harbor thresholds, indicating that there are no competitive
     concerns raised by the merger. Exhibit Nos. WHH-4 through WHH-7,
     Exhibit No. WHH-16, and Exhibit No. WHH-17 are sensitivity analyses
     performed using the Economic Capacity measure. These analyses are
     described under "Sensitivities" below. These analyses contain no
     screen violations, and indicate no competitive concerns associated
     with the merger.

AVAILABLE ECONOMIC CAPACITY

Q.   PLEASE SUMMARIZE THE AVAILABLE ECONOMIC CAPACITY MEASURE

A.   For the Available Economic Capacity analysis, I conducte my analysis
     using the base case assumptions, as described above regarding the
     Economic Capacity analysis. The only difference between the Economic
     Capacity measure and the Available Economic Capacity measure is that
     the latter accounts for retained load obligations. I based each
     supplier's load on information for 1999 retail loads, escalating those
     loads based on projected growth in electric demands throughout the
     region.(32)

     I assumed that each utility retains its full, historic load
     responsibility (i.e., I made no assumption about retail access for
     this analysis). In a slightly different context,(33) the Commission has
     indicated its distaste for hypothetical assumptions about the extent
     of retail access in markets where such access has begun. To avoid such
     hypothetical assumptions, I simply have assumed that retail access
     will not materially affect the amount that the various suppliers can
     make available to the wholesale market. In the Midwestern markets that
     are most likely to be problematic based on the Economic Capacity
     analysis, retail access either has not yet begun or is just now
     beginning. Hence, the zero access assumption for suppliers to these
     markets likely is not far off the mark.(34)

     The results of the analysis are shown in Exhibit No. WHH-3. The
     analysis shows that all of the indicators are well below the
     Commission's safe-harbor levels, again supporting my conclusion that
     the merger raises no competitive concerns.

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

32   See Exhibit No. WHH-12 for further details.

33   EME Homer City Generation, L.P., 86 FERC paragraph 61,016 (1999).

34   CILCO has not lost a significant amount of load to date due to
     restructuring in Illinois. Thus, the zero access assumption is applicable
     for CILCO.

SENSITIVITIES

Q.   PLEASE DESCRIBE THE SENSITIVITY ANALYSES YOU UNDERTOOK USING THE
     ECONOMIC CAPACITY MEASURE.

A.   The key variables in the FERC's delivered price test in this instance
     are related to transmission rates and transmission capacity. Since the
     Applicants are not contiguous and, in fact do not even have any common
     interconnections, these items are significant determinants of whether
     the companies appear as significant potential competitors in any
     destination market under the delivered price test.(35) I performed
     sensitivity analysis on RTO configurations, as described earlier. I
     also performed an analysis using increased transmission capacity.

     In the first RTO configuration sensitivity, I assumed that IPL was a
     member of the MISO or Alliance RTO pre and post-merger. This
     assumption does not significantly impact the results, as shown in
     Exhibit No. WHH-4 and Exhibit No. WHH-5. In these analyses, I assumed
     that Illinois Power and Commonwealth Edison were members of the MISO.

     In the second RTO sensitivity, I again assumed that IPL was a member
     of the MISO or Alliance RTO, but assumed that Illinois Power and
     Commonwealth Edison switch from the MISO to the Alliance RTO. This
     analysis again does not significantly impact the results. These
     results are shown in Exhibit No. WHH-6 and Exhibit No. WHH-7.

     I also conducted an additional sensitivity analysis wher I assumed all
     transmission rates were zero, except for incremental losses. This
     sensitivity is intended to be a limiting case showing the effects of
     market enlargement on the competitive effects of the merger. Again,
     even under this extreme assumption, the results were not significantly
     different than those found in the base case. These results are shown
     in Exhibit No. WHH-16.


     In the transmission capacity sensitivity, I assumed that full TTC
     values, rather than ATCs, were available to interconnect markets. This
     increases the ability of Applicants, and other potential suppliers, to
     deliver into the destination markets. Again, the results indicate that
     the merger raises no competitive concerns. These results are shown in
     Exhibit No. WHH-17.

     My conclusions are further supported by these sensitivit analyses.

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

35   Note that since the delivered price test does not accoun for opportunity
     costs, even if the analysis did find evidence of the Applicants'
     potentially serving common markets, it would not necessarily indicate any
     competitive concern, but rather that further investigation is required.


TOTAL CAPACITY

Q.   PLEASE DESCRIBE THE RESULTS OF THE TOTAL CAPACITY ANALYSIS.

A.   The Commission's traditional "hub-and-spoke" methodology could not be
     used directly in this instance since neither CILCO nor IPL would
     qualify as being in common markets, given the transmission network
     around the Applicants. Thus, I constructed the narrowest possible
     geographic market by including CILCO, IPL and their directly
     interconnected utilities. If the safe-harbor thresholds are met for
     the Total Capacity measure under this unrealistically narrow market
     definition, the Commission can be very certain that there are no
     competitive concerns arising from this measure from any other credible
     market definition.(36)

     The results are shown in Exhibit No. WHH-18. As shown, Applicants'
     combined market share is about 5 percent and the change in market
     concentration, as defined using the HHI indicator, is about 11.

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

36   I also excluded merchant capacity for purposes of this analysis. Including
     planned and operational merchant facilities would further reduce the
     Applicants' reported market shares.


UNCOMMITTED CAPACITY

Q.   PLEASE DESCRIBE THE RESULTS OF THE UNCOMMITTED CAPACITY ANALYSIS.

A.   The proposed merger raises no competitive issues regarding Uncommitted
     Capacity. First, IPL has no Uncommitted Capacity, even assuming
     conservative reserve margins, as shown in Exhibit No. WHH-19. Thus,
     there can be no merger effect under this measure. Similarly, based on
     historic load obligations CILCO does not have any uncommitted
     capacity, as shown in Exhibit No. WHH-19. Thus, there are no
     competitive concerns raised by my evaluation of the Uncommitted
     Capacity measure.

VERTICAL MARKET POWER

Q.   PLEASE DESCRIBE YOUR ANALYSIS OF VERTICAL MARKET POWER.

     A. I evaluated two vertical relationships in order to examine whether
     the proposed combination would facilitate vertical market power.
     First, I evaluated the combination of the companies' electric
     generating resources with their electric transmission assets. This
     merger should raise no vertical market power concerns in this respect.
     CILCO has committed to join the MISO and to creating an independently
     owned and governed institution under MISO to which it will turn over
     its retained control area operator functions. In addition, AES has
     committed that IPL, as an AES subsidiary, will join an RTO if
     necessary to avoid an evidentiary hearing on this Application.
     Furthermore, even absent the RTO commitments, Order Nos. 888 and 889
     ensure that transmission owners such as Applicants will not be able to
     foreclose access to any essential transmission facilities, including
     connecting new merchant plants to their grids. In its Order 2000
     compliance filing, IPL explains that it is an incidental transmission
     owner, and its system can be accurately described as either a high
     voltage distribution system or a local area transmission system.
     Neither Cinergy, nor any other utility directly interconnected with
     IPL, needs to use the IPL transmission system to reach any other
     utility. IPL has no TDUs that are not contractually covered with
     long-term contracts with IPL There is no schedule for retail access in
     Indiana that could create a market opportunity for competitors to
     serve IPL's retail customers.

OTHER POTENTIAL MARKET POWER ISSUES

Q.   ARE THERE ANY OTHER ISSUES THAT WOULD AFFECT COMPETITION IN THE
     RELEVANT MARKETS?

A.   As noted earlier, I have not formally analyzed competition in
     long-term markets which the Commission has found to be presumptively
     competitive (although I discuss entry in this section as well).

     In addition, in Order No. 888, the Commission in referring to a
     decision in Entergy Services, Inc. noted that "after examining
     generation dominance in many different cases over the years, we have
     yet to find an instance of generation dominance in long-run bulk power
     markets."(37) In the Merger NOPR, the Commission stated that "[a]s
     restructuring in the wholesale and retail electricity markets
     progresses, short-term markets appear to be growing in importance. The
     role of long-term capacity markets appears to be diminishing."(38)

     The possible exceptions to this presumption arise from vertical
     issues, such as control over transmission, fuels supplies or
     generating sites, that might block entry in the long-term. As
     discussed above, the RTO commitments of CILCO and AES (on behalf of
     IPL as an AES subsidiary) and the facts specific to IPL's transmission
     ensure that they cannot use their control over transmission to block
     entry into the long-run market.

38   Merger NOPR, FERC Stats. & Regs. paragraph 32,528 at 33,367.


Q.   WHAT IS THE ISSUE CONCERNING AN APPLICANT'S CONTROL OVER ESSENTIAL
     FUELS OR DELIVERY SYSTEMS?

A.   In the context of long-term capacity markets, the issue is whether the
     merging parties can foreclose or impede the entry of competing
     generators. As discussed above, CILCO is not in a position to
     foreclose current competitors. This review examines whether the merger
     would allow the combined company to impede entry by new competitors
     through the use of fuel supply inputs.

Q.   DO THESE APPLICANTS HAVE THE ABILITY TO FRUSTRATE ENTRY DUE TO THEIR
     CONTROL OVER FUELS OR FUEL DELIVERY SYSTEMS?

A.   No. As noted earlier, CILCO's natural gas transportatio assets serve
     basically only a small amount of CILCO owned facilities. Similarly,
     IPL's ownership of undeveloped coal reserves does not convey any
     ability of IPL to frustrate entry.

Q.   DO APPLICANTS EXERCISE CONTROL OVER THE AVAILABLE GENERATION SITES?

A.   No. I was unable to identify any special barriers to entry in this
     regard. While IPL and CILCO own a few potential generating sites,
     there are numerous other sites available, as shown by actual recent
     entry in the area.

     The geographic areas served by these Applicants are relatively small
     and the geographic area that must be included in any market definition
     that contains both Applicants encompasses quite a large region and
     includes many control areas. Entrants who could compete in areas
     potentially affected by this merger would not need to locate new
     facilities in Applicants' service areas or connect to Applicants'
     transmission systems. This is especially true given Applicants' open
     access transmission, overseen by the Commission, and the RTO
     membership and commitments discussed above.

Q.   IS THERE ANY EVIDENCE THAT THERE WILL BE ENTRY INTO THE MAIN AND ECAR
     MARKETS WITHIN THE NEXT FEW YEARS?

A.   Yes. First, entry can be accomplished in far shorter periods of time
     than were required with the large coal and nuclear generation
     facilities that used to be the chosen technology. According to the
     Department of Energy, conventional and advanced combined cycle
     generating units have a lead time of three years, and combustion
     turbines (i.e., peaking capacity) have a lead time of only two
     years.(39)

     There is substantial evidence that additional entry will occur and, in
     fact, is already taking place. For example, I identified more than
     17,000 MW of planned new generating capacity that has either entered
     service or is planned to enter service by around 2001 in just ECAR and
     MAIN.(40)

     There is also evidence of entry in the specific regions where IPL and CILCO
     operate. For example, in the past year, DTE Energy has located two
     combustion turbines in IPL's control area, and an affiliate of Enron Power
     Marketing has interconnected with the transmission systems of both IPL and
     Cinergy near Wheatland, Indiana. In Illinois, there were proposals for over
     2,400 MW of new generation from a variety of suppliers during the first
     quarter of this year.(41)

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

39   Assumptions to the Annual Energy Outlook 1999, Energy Information
     Administration, U.S. Department of Energy, December 1998, p. 59.

40   In my analyses, I included only about 6,500 MW of this generating
     capacity, representing only those units that are most likely to be
     in-service given the milestones that they have reached to date. These
     units are shown in workpapers.

41   See Power Generation Markets Quarterly (1st quarter, 2000), page 48.


7.       CONCLUSION

Q.   PLEASE SUMMARIZE YOUR RECOMMENDATION.

A.   I recommend that the Commission determine that this merger will not
     have an adverse effect on competition in markets subject to its
     jurisdiction.

Q.   DOES THIS COMPLETE YOUR TESTIMONY?

A.   Yes.

WILLIAM H. HIERONYMUS                           MEMBER OF THE MANAGEMENT GROUP


William Hieronymus has consulted extensively to managements of electricity
and gas companies, their counsel, regulators and policy makers. His
principal areas of concentration are the structure and regulation of
network utilities and associated management, policy and regulatory issues.
He has spent the last several years working on restructuring and
privatization of utility systems internationally and on changing regulatory
systems and management strategies in mature electricity systems. In his
twenty-plus years of consulting to this sector he also has performed a
number of more specific functional tasks including the selection of
investments, determining procedures for contracting with independent power
producers, assistance in contract negotiation, tariff formation, demand
forecasting and fuels market forecasting. Dr. Hieronymus has testified
frequently on behalf of utility clients before regulatory bodies, federal
courts and legislative bodies in the United States and United Kingdom. Dr.
Hieronymus was previously a Senior Vice President of Putnam, Hayes and
Bartlett (PHB), which merged with Hagler Bailly, Inc. in 1998. Hagler
Bailly, Inc. was purchased by the PA Consulting Group in October 2000. A
brief description of projects that he has led or contributed to include the
following.

ELECTRICITY SECTOR STRUCTURE, REGULATION AND
RELATED MANAGEMENT AND PLANNING ISSUES

U.S. ASSIGNMENTS

1. Dr. Hieronymus served as an advisor to a western electric utility on
restructuring and related regulatory issues and has worked with senior
management in developing strategies for shaping and adapting to the
emerging competitive market in electricity. As a part of this general
assignment he helped develop, and testified respecting, a settlement with
the state regulatory commission staff that provides, among other things,
for accelerated recovery of strandable assets. He also prepared numerous
briefings for the senior management group on various topics related to
restructuring.

1. For several utilities seeking merger approval he has prepared and
testified to market power analyses at FERC and before state commissions. He
also has assisted in discussions with the Antitrust Division of the
Department of Justice and in responding to information requests. The
analyses he has sponsored cover the destination market-oriented traditional
FERC tests, Justice Department-oriented market structure tests similar to
the Order 592 required analyses, behavioral tests of the ability to raise
prices and examination of vertical market power arising from ownership of
transmission and generation and from ownership of distribution facilities
in the context of retail access. The mergers on which he has testified
include both electricity mergers and combination mergers involving
electricity and gas companies.

1. For utilities and power pools preparing structural reforms, he has
assisted in examining various facets of proposed reforms. This analysis has
included both features of the proposals affecting market efficiency and
those that have potential consequences for market power. Where relevant,
the analysis also has examined the effects of alternative reforms on the
client's financial performance and achievement of other objectives.

1. For the New England Power Pool he examined the issue of market power in
connection with its movement to market-based pricing for energy, capacity
and ancillary services. He also assisted the New England utilities in
preparing their market power mitigation proposal. The main results of his
analysis were incorporated in NEPOOL's market power filing before FERC.

1. As part of a large PHB team he assisted a midwest utility in developing
an innovative proposal for electricity industry restructuring. This work
formed the basis for that utility's proposals in its state's restructuring
proceeding.

1. Dr. Hieronymus has contributed substantially to PHB's activities in the
restructuring of the California electricity industry. In this context he
also is a witness in California and FERC proceedings on the subject of
market power and mitigation.

1. He has testified in state securitization and stranded cost quantification
proceedings, primarily in forecasting the level of market prices that
should be used in assessing the future revenues and the operating
contribution earned by the owner of the utilities' assets in energy and
capacity markets. The market price analyses are tailored to the specific
features of the market in which the utility will operate and reflect
transmission-constrained trading over a wide geographic area. He also has
testified in rebuttal to other parties' testimony concerning stranded costs
and assisted companies in internal stranded cost and asset valuation
studies.

1. He has contributed to the development of benchmarking analyses for U.S.
utilities. These have been used in work with PHB's clients to develop
regulatory proposals, set cost reduction targets, restructure internal
operations and assess merger savings.

1. Dr. Hieronymus was a co-developer of a market simulation package that PHB
has tailored to region-specific applications. He and other PHB personnel
have provided numerous multi-day training sessions using the package to
help our utility clients in educating management personnel in the
consequences of wholesale and retail deregulation and in developing the
skills necessary to succeed in this environment.

1. Dr. Hieronymus has made numerous presentations to U.S. utility
managements on the U.K. electricity system and has arranged meetings with
senior executives and regulators in the U.K. for the senior managements of
U.S. utilities.

1. For a task force of utilities, regulators, legislators and other
interested parties created by the Governor's office of a northeastern state
he prepared background and briefing papers as part of a PHB assignment to
assist in developing a consensus proposal for electricity industry
restructuring.

1. For an East Coast electricity holding company, he prepared and testified
to an analysis of the logic and implementation issues concerning
utility-sponsored conservation and demand management programs.

1. In connection with nuclear generating plants nearing completion, he has
testified in Pennsylvania, Louisiana, Arizona, Illinois, Missouri, New

INTRODUCTION

This appendix describes the data required to conduct the market power
analyses as well as the source and methodology used to collect and input
the necessary data. The delivered price test requires estimating the
generating resources for each of the potential suppliers in the model,
specifying the transmission network that these suppliers can use to reach
the relevant destination market, load in each market and the destination
market price. All of the relevant data used in the analyses is included in
my workpapers.

PA Consulting's Competitive Analysis Screening model ("CASm") was used to
conduct the delivered price test. A complete description of CASm is
provided in Exhibit No. WHH-13. Briefly, CASm is a linear programming model
developed specifically to perform the calculations required in undertaking
the delivered price test. The model includes each potential supplier as a
distinct "node" or area that is connected via a transportation (or "pipes")
representation of the transmission network. Each link in the network has
its own non-simultaneous limit and cost. This limit is the control area to
control area limit. Flow restrictions can also be applied across sets of
links to capture any relevant simultaneous limits.

Potential suppliers are allowed to use all economically and physically
feasible links or paths to reach the destination market. In instances where
more generation meets the economic criterion of the delivered price test
than can actually be delivered on the transmission network, scarce
transmission capacity is allocated based on a proration method described
below.

REGIONS MODELED

The list of utilities (and corresponding abbreviations used in other
exhibits) is included in Exhibit No. WHH-14. Included in the analysis are
utilities from each of the following NERC regions:(1)

o  East Central Area Reliability Coordination Agreement ("ECAR")

o  Mid-America Interconnected Network ("MAIN")

o  Mid-Atlantic Area Council ("MAAC", which is PJM)

o  Southeastern Electric Reliability Council ("SERC")

o  Southwest Power Pool ("SPP")

o  Mid-Continent Area Power Pool ("MAPP")

o  NYISO portion of the Northeast Power Coordinating Council ("NPCC")

This list of candidate suppliers does not pre-judge the question of the
geographic scope of the specific destination market, which is determined
via the delivered price test.(2)

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

(1)  PJM, NYPP regions were aggregated into single areas. AES' generation in
     NEPOOL and Ontario Hydro were conservatively included as part of the NYPP
     region.

(2)  This list was selected in recognition of the Commission's guidance
     regarding the number of wheels a potential supplier can realistically
     travel and still be considered a player in the destination market. For
     example, in FirstEnergy, the Commission limited the number of wheels "a
     supplier could reasonably travel to reach the destination market,"
     recognizing that "[m]ore distant suppliers would face considerable losses
     and transmission costs." 80 FERC paragraph 61,039 at 61,104. In
     FirstEnergy, the Commission limited the potential suppliers to those within
     four wheels. Ibid. Also, the request for comments on the use of computer
     models in merger analysis suggests that "three wheels has been deemed
     adequate." Inquiry Concerning the Commission's Policy on the Use of
     Computer Models in Merger Analysis, Notice of Request for Written Comments
     and Intent to Convene a Technical Conference, Docket No. PL98-6-000, April
     16, 1998, page 24. Including a broader geographic region implies adding
     additional potential suppliers not controlled by the Applicants; thus,
     defining the set of potential suppliers in this manner is conservative.

ESTIMATING SUPPLY RESOURCES FOR EACH NODE

Supply curves, consisting of a price and quantity for each node, are
developed and entered into CASm.(3)

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

(3)  I analyzed market participants as if the electric utility mergers pending
     before the Commission had been approved and mergers consummated.


SUPPLY CAPACITY

The main source for data on generating plant capability, including
non-utility generators ("NUGs"), is the Form EIA-411. I used the
publications dated April 2000 (the most up-to-date data available),
supplemented by earlier editions as necessary. The EIA-411 provides data on
summer and winter capacity, planned retirements and additions and
jointly-owned units. For jointly-owned plants, shares were assigned to each
of the respective owners. Summer ratings were used for the summer and
shoulder periods and winter ratings for the winter period. The data were
adjusted to reflect planned retirements and capacity additions through
2001, as detailed in the EIA-411 forms.

I included those utility and merchant plants that are scheduled to enter
service by 2001. However, I limited these new plants to those that have
passed project, regulatory or financial hurdles (e.g., interconnection
agreements, financing, regulatory approvals or site permits), or which have
started construction. The specific merchant plants included are sho n in
workpapers. Each supplier's generating resources also were adjusted to
reflect long-term capacity purchase and sales.(4) Purchases and sales (of
one year or more duration) were identified from publicly available
information, such as FERC Form 1 and EIA Form 412 filings (or databases
based on these forms), Form EIA-411, individual utility resource plans and
NERC's Electricity Supply and Demand ("ES&D") database. These public data
on purchases and sales, however, are not entirely complete or consistent
across sources.

To the extent a utility has sold capacity under a long-term agreement,
ownership over that resource is assumed to pass to the buyer.(5)
Accordingly, as with jointly-owned units, generation ownership was adjusted
to reflect the transfer of control by assuming that the sale resulted in a
decrease in capacity for the seller and a corresponding increase in
capacity for the buyer. Consistent with guidance provided in Appendix A, it
was assumed that system power sales were comprised of the lowest-cost
supply for the seller unless a more representative price could be
identified.(6) To the extent that long-term sales could be identified
specifically as unit sales, the capacity of the specific generating unit
was adjusted and the variable element of the purchase price attributed to
the sale was the variable cost of the unit. The dispatch price for system
purchases was based on the energy price reported for long-term purchases in
the FERC Form 1 where such purchases could be identified and a variable
cost price determined.(7) The capacity representing firm purchases and sales
and shares of jointly-owned units was "moved" in the model from its actual
physical location to the geographic location of the buyer. This treatment
is consistent with using the public source ATC transmission data that
represent the incremental amount of capacity available for conducting
trades after accounting for base flows on the system. Thus, the methodology
is consistent with the transmission data that was used to reflect available
transmission capacity.

Since the delivered price test is intended to evaluate energy products, the
capacity (in MWs) reported in the Form EIA-411 was de-rated to approximate
the actual availability of the units in each period. That is, it was
assumed that generation capacity would be unavailable during some hours of
the year for either (planned) maintenance or forced (unplanned) outages.
Data reported in the most recent NERC Generating Availability Data System
was used to calculate the "average equivalent availability factor" to
estimate total outages, and the "average equivalent forced outage rate" to
estimate forced outages for fossil and nuclear plants.(8) Scheduled
maintenance was assumed to occur only during the non-peak (shoulder)
seasons and forced outages were assumed to occur uniformly throughout the
year.

This treatment of generating availability is designed to account for the
fact that resource availability changes by season. It is consistent with
how the time periods evaluated were defined (based on similar load hours in
each season, rather than by similar load hours for the entire year), and
with specifying transmission capacity by season, as discussed below.(9)

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

(4)  This treatment does not include requirements contracts.

(5)  utility.

(6)  "[T]he lowest running cost units are used to serve native load and other
     firm contractual obligations" (Appendix A, p. 11). The lowest-cost supply
     that was available year-round (i.e., excluding hydro) was used.

(7)  In instances where the purchases could not be matched with FERC Form 1
     data, the dispatch price was estimated.

(8)  These data were supplemented, where necessary, by data from other public
     sources such as NERC and Electric Power Research Institute.

(9)  A spreadsheet detailing the capacity and price of the units in the model is
     included in a set of workpapers filed with the application.



SUPPLY COST

In calculating the supply curves, supply from each unit was assumed to be
available at any price above its incremental cost (the delivered price test
assumes supply is economic if its cost is up to 105% of the competitive
market price). The incremental cost is calculated by multiplying the fuel
cost for the unit by the unit's efficiency (heat rate) and adding any
additional variable costs that may apply, such as costs for variable
operations and maintenance and costs for environmental controls.(10) Data
were taken from the following sources:

o   Heat rates - EIA Form 860, supplemented in a few instances by data from
    Form EIA-411. (Note that the most recently available data is from the
    1995 Form 860.) IPL does not report any data in the EIA Form 860,
    therefore estimates from RDI's PowerDat database were used for the IPL
    units reported in PowerDat. In other instances where information is not
    available, an estimate is applied based on unit type.

o   Fuel costs - Form 423. The estimated dispatch cost is based on spot or
    interruptible fuel prices for a twelve month period ending March 2000.
    Seasonal estimates were derived from the monthly data and applied to
    derive dispatch costs by season. To the extent all fuel purchases in
    that period had been made under contract rather than at spot prices, an
    incremental price based on reported spot or interruptible prices in the
    relevant region was estimated. Fuel prices were escalated to 2001 based
    on the forecasts in the EIA Annual Energy Outlook.

o   Variable O&M - $1/MWh for gas and oil steam units, $3/MWh for scrubbed
    coal-fired units and $2/MWh for other coal-fired units (generic
    estimates based on trade and industry sources). Additional VO&M adders
    for other unit types are shown in workpapers.

o   SO2 adder - $162/ton. The adder was applied to all relevant units
    assuming that Phase 2 had been implemented as planned; all units are
    assumed to pay an adder based on the SO2 content of the fuel burned.

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

(10) For NUGs, the incremental costs were estimated based on the energy price
     reported in relevant regulatory filings, if available. Otherwise, NUGs were
     assumed to be must-run and the variable costs set to zero. New merchant
     capacity included in the analysis was priced assuming a heat rate of 10,000
     Btu/kWh for combustion turbines and 7,000 Btu/kWh for combined cycle
     plants. Variable O&M was also applied to the new units consistent with the
     assumptions for existing units.


TRANSMISSION NETWORK

Appendix A specified that the transmission system be modeled on the basis
of inter-control area ATCs or TTCs using transmission prices based on
transmission providers' maximum non-firm OATT rates except where lower
rates could be clearly documented. This dictated a transportation
representation of the transmission network and the structure of CASm was
designed to conform to Appendix A. This representation remains appropriate
for portions of the United States, where transmission service is generally
provided under each transmission provider's Open Access tariff. Basing
tariffs on OATT rates is increasingly undercut by RTO transmission pricing
arrangements, however, and the Commission has instructed applicants to
account for them.(11) Also, proposed regional transmission organizations that
are not yet operating, such as the Midwest ISO and Alliance RTO, will
reduce pancaking of control area to control area transmission rates by
charging only one rate to travel through or out of their systems. Finally,
some pricing systems, such as MAPP's flow-based method for determining
transmission rates, create a more complex matrix of transmission prices
that is not wholly consistent with a transportation model. Nonetheless,
with some simplification, each of these alternative arrangements can be
modeled in CASm, as described below.

TRANSMISSION CAPACITY

Limits were placed on the amount of capacity that could be transferred over
the transmission network by both non-simultaneous control area to control
area limits and simultaneous interface limits. Control area-to-control area
limits are still applicable in most of the regions modeled. In the SPP and
MAPP regions, however, transmission reservations are no longer based solely
on control area to control area limits, but consider the impact of any
particular transfer on key elements of the network (termed "flowgates").
Control area to control area transmission capability was taken primarily
from postings on the Open Access Same-Time Information System or "OASIS."
OASIS reports Total Transmission Capability ("TTC"), firm Available
Transmission Capability ("ATC") and non-firm ATC. Data generally are
provided monthly for a twelve-month period starting with the next month.
Monthly non-firm ATCs postings from the third quarter of 2000 were used in
most instances.(12) Seasonal differences in transmission capability were
captured by using the average of June-August postings to represent a summer
capability; the average of December-February postings to represent a winter
capability; and the average of remaining months to represent a shoulder
capability.(13)

Using an ATC value, as opposed to a TTC value, is appropriate given the
manner in which generating resources were moved to each node to reflect for
jointly-owned units and long-term purchases and sales. Non-firm ATCs are
the appropriate input assumption for transfer capability since Economic
Capacity and Available Economic Capacity are intended to reflect
competition in non-firm energy.(14) I did analyze results using TTCs as a
sensitivity, as discussed in my testimony.

As noted above, the SPP and MAPP regions are now providing the public OASIS
postings for its member companies on the basis of flowgates rather than
posting point-to-point ATCs. Data from June 1999 were used for the SPP
region. For MAPP, some of the individual companies still list control area
to control area limits and for these links, data retrieved during the third
quarter 2000 were available. For the remaining MAPP links, data from the
fourth quarter of 1998 was used.(15)

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

(12) The exception is for some interfaces in MAPP and the SPP, as discussed
     below.

(13) In instances where two parties post different capability for the same path,
     the lower of the reported values was generally used. This assumption was
     made on the basis that if a party sought use of a particular path, the
     lower of the reported values would be applicable unless the utilities at
     both the receipt and delivery points could agree differently.

     In addition, third-party postings, i.e., ATCs from one utility to another
     utility that it is not directly interconnected with, were not included in
     the analyses.

(14) In reality, utilities frequently post the same value for both firm and
     non-firm ATCs.

(15) Given that data is generally reported for the next 12 months, this implies
     that the fourth quarter 1998 data covered through the winter of 2000.


TRANSMISSION RATES

The Commission's Appendix A guidelines implicitly assume a depiction of the
transmission system wherein control area to control area transactions occur
using each of the relevant control area's Open Access (Order 888) tariffs.
Appendix A also instructs applicants to model any applicable discounts that
are systematically available, and to account for regional transmission
organizations as they arise. In implementing transmission rates into the
analysis, regardless of the transmission regime, it has been assumed that
transmission charges would be incurred for the transmission system where
the generator is located and for wheeling the power through intermediate
systems, but not for the destination market. No transmission charge is
included for the transmission system in which the load is located. This has
no impact on the analysis, since including this charge (the transmission
charge included in the bundled rate of the transmission provider in the
area where the customer is located, or the "zonal" or postage stamp charges
in the case of an RTO) would symmetrically raise the delivered cost for
each supply to reach the destination market by the same amount. Thus, the
relative economics would not be impacted.(16) Losses, which are assumed to be
3.0 percent, are assessed for each wheel incurred along the path to deliver
power to the destination market but are not added for the final wheel into
the destination market.

In the regions potentially impacted by this merger, there are significant
regional transmission arrangements that can alter the cost of transmission
(indeed, lowering the costs in each instance), either by providing for
lower rates or by eliminating pancaking of transmission rates. The MISO and
Alliance RTOs, which are assumed to exist in all of the scenarios that I
analyzed, reduces the cost of transmission by eliminating pancaking.
Additionally, SPP and MAPP both have distance sensitive rates available
that allow users to transact under lower transmission costs than control
area to control area pancaked 888 rates. (17) These alternative transmission
tariffs were incorporated into CASm, with some simplifying assumptions
described below.

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

(16) Likewise, distinctions between "bundled and unbundled" transactions, which
     affect the price paid for the final delivery of power, do not affect the
     relative delivered prices of competing supplies.

(17) MAPP has in place a regional tariff that allows parties to transact using
     rates based on the impact of each trade on various transmission facilities
     throughout the affected network, rather than the traditional contract path
     methodology. The MAPP rate structure was implemented in CASm by assuming
     that the MAPP utilities scheduled and paid for transmission service along a
     contract path basis.

     SPP has a regional tariff that provides for distance sensitive rates. The
     SPP tariff lists rates between any two eligible members and, like the MAPP
     rate, was implemented along a contract path. In CASm, discounts were
     applied to specific paths in the SPP and by season based on the historical
     discount rates applied since the SPP tariff went into effect.


Order 888 Tariffs

Consistent with Order No. 592, the ceiling rates in Exhibit 8 (Non-Firm
Point-to-Point Transmission Service) of each utility's Order No. 888
filings were used for utilities that are not part of RTO arrangements.(18) In
many instances, utilities report both on-peak and off-peak ceiling rates in
its Order No. 888 filing. If so, then the applicable transmission rate for
the on- and off-peak periods were used. If not, then the filed ceiling rate
was applied for all periods. Ancillary service charges from Exhibits 1
(Scheduling, System Control and Dispatch Service) and 2 (Reactive Supply
and Voltage Control from Generation Sources Service) of Order No. 888
filings were added where applicable to determine the final rates.

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

(18) In some cases, individual utility rates also are relevant to the zonal
     rates and for computing "through and out" rates within RTOs. In instances
     where transmission data were not reported in dollars per MWh, the $/MW
     rates were converted to $/MWh rates using the "Appalachian" method. 39 FERC
     paragraph 61,296 at 61,965.


Midwest ISO and Alliance RTO

Two rates were derived for each of the RTOs included in the analysis.
First, a weighted average tariff rate was calculated and applied for
transactions that travel "through" and "out" of the RTO and is applied for
all paths from a RTO member to a non-RTO member. This rate is calculated as
the weighted average of all of the RTO members rates using publicly
available data for the weights and tariff data from the individual
company's Order 888 tariffs.(19) The second rate, the "in" and "within"
rate, is applicable for trades into and within the RTO. This rate is based
on the zone where the load is located. As discussed earlier, the final
import rate is not applied in CASm; thus the zonal RTO rates are not used
in the analyses. The applicable RTO rates change depending upon which
utilities are included in each RTO and a full derivation of the applicable
RTO rates is provided in workpapers.

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

(19) The RTO rate derivations were based on an illustrative calculation shown in
     a MISO filing with FERC, which shows a unified tariff rather than a
     calculation based on weighted averages per se. This should differ from the
     methodology that I have used only in that the inter-system diversity (about
     2 percent) would be taken into account using the methodology shown in the
     filing.


ALLOCATION OF LIMITED TRANSMISSION

Appendix A notes that there are various methods for allocating
transmission, and that Applicants should support the method used.(20) There
are two basic approaches to allocating limited transmission capacity:
economic and pro rata. Under an economic allocation, available transmission
is assigned on the basis of the cost of the capacity (energy) competing to
use limited transmission capability. The lowest cost capacity is assumed to
have a priority in using the transmission. Higher cost generation is
excluded, despite its having costs below 105 percent of the destination
market price. In contrast, pro rata methods of allocation treat all
generation that meets the delivered price test equally in allocating scarce
transmission.

The paradigm lying behind the proration required by the Order No. 592
delivered price test (whether economic or pro rata methods are used) can be
likened to a tree, for which the root is the destination market. At the
furthest extremes are small branches, each one of which is connected to a
single larger branch and so on until the trunk and root are reached. There
is no ambiguity concerning the path. Hence, at every node (joining with a
large branch), all of the capacity that can access the limited capacity of
the branch can be calculated; each small branch's capacity is reduced
proportionately to the capacity of the branch. This can be repeated
successively, moving inward to the destination market. Even taking into
account the simplifications required by a "transportation" representation
of transmission, real world transmission systems are more complex. The
"small branch" distant utilities have multiple paths by which a destination
market can be reached. In some cases, paths may first be in a direction
away from the destination market, looping around onto another path to it.
An analysis that takes this important complexity into account is
computationally very difficult. Allocation methods differ partly in terms
of how the problem is simplified in order to make computation tractable.
This is described further in Exhibit No. WHH-13.

The major drawback of using an economic allocation is that it tends to
continually reallocate the same low cost energy, principally hydro and
nuclear energy (and non-dispatchable NUG capacity) over and over to each
destination market in the Economic Capacity measure. This occurs partly
because Appendix A does not take into consideration the opportunity cost of
supplying alternative markets to the destination market being analyzed,(21)
but primarily because each destination market is analyzed separately. This
allows the same low cost supplies to be allocated to each of the
destination markets. While this is not wholly inappropriate, since the
purpose of Appendix A is to measure potentially competing supply to each
destination market, it does mean that the very low cost supplies can travel
far and wide and occupy a highly disproportionate share of available
transmission. This repeated allocation of the same energy is particularly
troublesome given the large area involved in the analysis in the instant
case. This flaw is less severe in the Available Economic Capacity measure,
where the native load obligations absorb each control area's lowest cost
resources.

For purposes of this analysis, I allocated limited transmission capacity
using a "squeeze-down" method, so-named because it seeks to prorate
capacity at each node. I believe it to be the closest approximation to what
the Commission applied in the FirstEnergy merger(22) that is computationally
feasible. Under this method, shares of available transmission are allocated
at each interface, diluting as they get closer to the destination market.
When there is economic supply (i.e., having a delivered cost less than 105
percent of the destination market price) competing to get through a
constrained transmission interface into a control area, the transmission
capability is allocated to the suppliers in proportion to the amount of
economic supply each supplier has outside the interface.

Shares on each transmission path are based on the shares of deliverable
energy at the source node for the particular path being analyzed. The
calculations start at the outside of a network defined with the destination
market as its center and end at the destination market itself. A series of
decision rules are required to accomplished this proration. The purpose of
these decision rules is limited to assigning a unique power flow direction
to each link for any given destination market analysis. Once the links are
given a direction, the complex network can be solved. CASm implements a
series of rules to determine the direction of the path. The first rule (and
the one expected to be applied most frequently) is based on the direction
of the flow under an economic allocation of transmission capacity. Other
options take into consideration the predominant flow on the line based on
desired volume (the amount of economic capacity seeking to reach the
destination market, the number of participants seeking to use a path in a
particular direction and the path direction that points toward the
destination market.

The model proceeds to assign each supplier at each node a share equal to
their maximum supply capability. At each node, "new" suppliers (those
located at the node outside of the next interface) are given a share equal
to their supply capability and the shares of more distant suppliers (those
who have had to pass through interfaces more remote from the destination
market in order to reach the node) are scaled down to match the line
capacity into the node. Ultimately, the shares at the destination market
represent the prorated shares of economic capacity that is economically and
physically feasible.

     suppliers could be subject to the same transmission path limitation to
     reach the same destination market and the sum of their economic generation
     capacity could exceed the transmission capability available to them. In
     these cases, the ATC must be allocated among the potential suppliers for
     analytic purposes. There are various methods for accomplishing this
     allocation. Applicants should support the method used.")

(21) Indeed, if opportunity costs were taken into account, and one was
     considering a regional dispatch, available transmission capacity
     appropriately would be allocated on the basis of economics.

     there was more economic capacity (or available economic capacity) outside
     of a transmission interface than the unreserved capability would allow to
     be delivered into the destination market, the transmission capability was
     allocated to the suppliers in proportion to the amount of economic capacity
     each supplier had outside the interface.")


SIMULTANEOUS IMPORT CAPABILITY

In order to determine simultaneous transmission limitations, I utilized
data from various NERC transmission assessment reports. These reports
indicate common limiting facilities for multiple transmission
interconnections into a single market. For those instances where a common
facility limits imports over multiple paths, I assumed that the maximum
import capability was no greater than the maximum of the individual path
limits. This is consistent with the Commission's approach outlined in the
FirstEnergy decision.(23) All of the simultaneous limits applied in the model
are included in my workpapers.

LOAD DATA AND TIME PERIODS ANALYZED

The most up-to-date hourly load data filed with the Commission (generally
covering 1999 calendar year) was used for two purposes: (1) as a measure of
native load responsibility for the Available Economic Capacity measure and
(2) to determine the correct seasonal time periods to evaluate (i.e., to
group similar hours).

LOAD DATA FOR AVAILABLE ECONOMIC CAPACITY

For the Available Economic Capacity measure, I generally used hourly load
data from FERC Form 714 for the most recent period available at the time
this analysis was undertaken. For the few utilities that do not file Form
714s (e.g., some cooperatives and municipal utilities) or whose data were
otherwise unavailable, data from the EIA-411 along with a load shape based
on those of similar utilities for which data were available were used.(24)

As noted in my testimony, this analysis did not assume any load loss due to
retail access. Nor did it assume that the divestitures available economic
capacity; rather generation and historic (i.e., pre-divestiture) loads were
matched up.

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

(24) The load data were escalated to 2001, based on the projected energy growth
     rate reported in the EIA-411 or FERC Form 714. If such data were not
     available, a regional growth rate reported for the relevant NERC region was
     used.


PERIOD DEFINITIONS BASED ON HOURLY LOAD DATA

Appendix A requires applicants to evaluate the merger's impact on
competition under different system conditions. For example, aggregating
summer peak and shoulder peak conditions may mask important differences in
unit availability and therefore a merger could potentially impact
competition differently in these seasons. Thus, applicants are directed to
evaluate enough sufficiently different conditions to show the merger's
impact across a range of system conditions. On the other hand, the Merger
Guidelines discuss the ability to "sustain" a price increase, and a finding
that a structural test (HHI) that violates the safe harbor for some sub-set
of hours during the year may not be indicative of any market power
problems. Therefore, there is a trade-off between defining enough periods
to capture the merger's impact under different system conditions and
defining periods so narrowly as to make the resulting concentration
statistics irrelevant to an evaluation of whether a price increase could be
sustained. The data and methodology I used are described in my testimony.

PRICE DATA

In order to select the appropriate price bands to analyze, I prepared a
comparison of system lambda and price data in Power Markets Week. These
data are summarized in Exhibit No. WHH-15 and described in my testimony.


                                                              Exhibit No. WHH-13

                COMPETITIVE ANALYSIS SCREENING MODEL (CASm)

PA Consulting developed the Competitive Analysis Screening model
("CASm_v87") to perform the calculations required in order to conduct a
market power analysis under Appendix A of the FERC Merger Policy Statement
("Order No. 592" or "Appendix A").(1) The delivered price test specified in
Appendix A requires an analysis of market concentration for a large number
of markets under a number of different conditions. CASm facilitates this
process by performing the required calculations.

The primary requirement of Appendix A is to assess potential suppliers to a
market using a "delivered price test". This test involves comparing
variable generation costs plus delivery costs (transmission rates,
transmission losses and ancillary services) to a "market price." If the
delivered cost of generation is less than 105 percent of the market price,
the generation is considered economic. Economic generation is further
limited to the amount that can be delivered into the market, given
transmission capability and constraints.

CASm implements the prescribed delivered price test by determining -- for
each destination market, for each relevant time period, and for each
relevant supply measure -- potential supply to the destination market both
pre- and post-merger. In effect, CASm determines the relevant geographic
market by applying the delivered price test, based on the economics of
production and delivery (transmission rates, transmission losses and
ancillary services), and also based on the physical transmission capacity
available to the competing suppliers on an open access basis. This requires
a delivery route for the energy on the established transmission paths, each
of which has a capability, transmission rate and transmission losses
associated with it. CASm finds the supply that can be delivered to the
destination market consistent with cost minimization and the delivered
price test.

As a formal matter, CASm minimizes the production and transmission costs of
supplying demand in the destination market. Any shortfall in demand is
filled by a hypothetical generator located in the destination market that
can produce an unlimited amount of energy at 105 percent of the market
price. On this basis, any supplier who can profitably supply energy to the
destination market will do so, to the maximum extent that their cost
structure and the transmission system allow. This formulation ensures that
no supplied generation is uneconomic; the hypothetical generator will
undercut all such suppliers.

CASm determines pre- and post-merger market shares and calculates
concentration (as measured by the Herfindahl-Hirschman Index, or HHI) and
the change in HHIs. To undertake these analyses, CASm solves a series of
scenarios involving a network of interconnected suppliers. By limiting
suppliers based on the economics of generation and delivery, or by limiting
the interconnections between those suppliers based on the transmission
capability, each Appendix A analysis can be completed. CASm includes a
simplified depiction of the transmission system, essentially a system of
"pipes" with independent, fixed capacity between and among utilities.

The following sections describe:
1. What data inputs are required to operate CASm

1. How different analyses are undertaken in CASm

2. What outputs CASm produces; and

3. How CASm is implemented.

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

(1)  CASm was developed by predecessor companies, PHB and PHB-Hagler Bailly, and
     has been used in analyzing numerous mergers and power plant acquisitions in
     proceedings before the Commission.


INPUT DATA

MARKET PARTICIPANTS

The largest element of the required data for CASm relates to individual
market participants, which generally are utilities with both generating
capacity and load obligations. In addition, some market participants may
have load obligations but no generating capacity (e.g., transmission
dependent utilities, or TDUs) or have generating capacity but no load
obligations (e.g., merchant capacity). CASm regards all distinct market
participants as having the ability to both supply and consume electricity.
The particular circumstances of each analysis will determine the extent to
which each activity is possible.

Nodes

In CASm, a node is a location where electricity is generated or consumed,
or where it may "split" or change direction. All market participants are
defined as having a unique node, and hence unique location in the
transportation network. Total simultaneous import limits can be imposed at
each node to mirror reliability restrictions. Output Capability

Each market participant may have generating ability, which is defined
generically in terms of any number of "tranches" of generation having both
a quantity (MW) and dispatch cost ($/MWh). This output capability and cost
may differ over time, for example because of planned and unplanned outage
rates and fuel prices. CASm has a number of data inputs available for
modifying the underlying physical availability of generating assets to get
the relevant "supply curve" for any given model period. CASm can also cover
generation tranches to account for load obligations at each node (used for
the Available Economic Capacity measure, as discussed below).

Destination Market Prices

For each destination market, a prevailing market price is defined. The
destination market price is used to calculate a threshold price that
potential suppliers must meet to be included in the market for
economic-based analyses (that is, the "delivered price test").

INTERCONNECTIONS

Interconnections represent the network that links market participants
together. These interconnections are represented as a "transportation"
network, where flows are specifically directed.

Lines

A line between two nodes in CASm may represent either a single line, or the
combined effect of a number of lines. Each line has an upper limit on the
flow, and losses may occur on the line. Since capacity on the line may
represent physical limits less firm commitments, limits are allowed to be
different, depending on the direction of the flow. Limits on the
simultaneous flow on combinations of lines can be imposed to simulate the
effect of loopflow or reliability constraints.

SCENARIOS

The final input area for CASm is related to scenario definition. Scenarios
define which parties are considering merging, which load periods are
relevant, and so on. In effect, the scenarios define a number of individual
analyses to be performed, and how they should be compared to each other for
reporting purposes.

ACCOUNTING FOR OWNERSHIP

It is sometimes necessary to merge the results for several nodes, or to
split them, based on ownership changes between scenarios. CASm has a
"report as" function that will merge the results of several nodes into a
single to correctly account for ownership. REQUIRED CALCULATIONS

Appendix A's delivered price test defines two different supply measures to
evaluate:

4. ECONOMIC CAPACITY is the amount of capacity that can reach a market at a
cost (including transmission rates, transmission losses and ancillary
services) no more than 105 percent of the destination market price.

5. AVAILABLE ECONOMIC CAPACITY is the amount of Economic Capacity that is
available after serving native load and other net firm commitments with the
lowest cost units. For every analysis, the following process is undertaken:
First, a Linear Programming (LP) problem is solved. The LP construction is
slightly different, depending on the underlying assumptions of each of the
supply measures. CASm includes two options for allocating scarce
transmission capacity. CASm has a "proration" option, which is called
"squeeze-down". This is discussed in detail below. Another option is an
economic allocation of limited transfer capability. Under this option,
where available supply exceeds the ability of the network to deliver that
capacity to the destination market, the least-cost supply is allocated the
available transmission capacity.(2)

The final step involves calculating what can be delivered to the
destination market, after accounting for line losses. CASm allocates total
system losses amongst suppliers on the basis on how much they injected, and
how far away (how many wheels) they are from the destination market.

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

(2)  CASm can be modified to apply different proration method when appropriate
     for some analyses. ECONOMIC CAPACITY


 For the Economic Capacity analysis, CASm solves an LP with the following
     form: minimize cost for supplies at the destination market

         subject to:

                  supply cost at destination < system lambda + 5%, for all
                  suppliers

                  supply < quantity(3), for each node and tranche

                  supply + flows in = flows out + "demand", for each node

                  line flows are adjusted for losses, for all
                  interconnections

                  line flows < available limit, for all interconnections
                  (constrained network only)

                  sum over lines (flow * simultaneous factor) <=
                  simultaneous limit, for all limits

                  sum over nodes (net injection * flowgate factor) <=
                  flowgate limit, for all limits

The objective is slightly different when transmission capacity is to be
prorated. The objective then becomes:

         minimize cost for supplies at the destination market; and

         minimize divergence from calculated pro rata "share", for
         each supplier

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

(3)  Available quantity may be modified. See discussion in the Output Capacity
     section.


AVAILABLE ECONOMIC CAPACITY

For the Available Economic Capacity analysis, CASm solves an LP with the
following form:

         minimize cost for supplies at the destination market

          subject to:

                  supply cost at destination < system lambda + 5%, for all
                  suppliers

                  supply < quantity (less native load), for each node and
                  tranche

                  supply + flows in = flows out + "demand", for each node

                  line flows are adjusted for losses, for all
                  interconnections

                  line flows < available limit, for all interconnections
                  (constrained network only)

                  sum over lines (flow * simultaneous factor) <=
                  simultaneous limit, for all limits

                  sum over nodes (net injection * flowgate factor) <=
                  flowgate limit, for all limits

This is different from the economic capacity analysis only to the extent
that potential suppliers are required to meet their load obligations prior
to participating in the market.
When transmission capacity is to be prorated the objective becomes:

         minimize cost for supplies at the destination market; and

         minimize divergence from calculated pro rata "share", for each
         supplier

OUTPUTS

The primary output from CASm is a report that summarizes the results of
different analyses. For each destination market, load period and FERC
analysis type, CASm reports the following for both pre- and post-merger:

6. Supplied MW

7. Market Share

8. HHIs

This report also shows the change in HHIs post-merger compared to
pre-merger. CASm also produces a transmission report that shows the detail
of each node, and the injections and flows between them. Finally, a summary
of the results for each market is also produced.

"SQUEEZE-DOWN" PRORATION

In the "squeeze-down" proration algorithm, prorated shares on each line are
based on the weighted shares of deliverable energy at the source node for
that line. As discussed below more fully below, weighted shares at the
destination market node are calculated by a recursive algorithm that starts
at the "outside" of the network, calculating shares on each line until it
reaches the "middle". Specifically, where available supply exceeds the
ability of the network to deliver that capacity to the destination market,
suppliers are allocated shares at each node, and hence each outgoing line,
based on the results of an algorithm that considers both supply and
transfer capability at each node. Starting at the "outside" of the network,
CASm calculates a share at each node that is based on a proportion of the
incoming transfer capability (and the share of that capability allocated to
each supplier), and the maximum economic supply available at that node.
When the algorithm reaches the destination market, a total share of the
incoming transfer capability has been determined. This algorithm requires
that all possible paths are simultaneously feasible, which, in turn,
requires that each line be assigned a unique "direction". The steps of the
proration algorithm include:

1. A C++ program enumerates all possible paths
to the destination, the cost of transmission on each path and the maximum
possible flow on the path. A "wheel limit", or maximum number of
point-to-point links, may be imposed on paths.

2. The minimum "entry cost" for each supplier is calculated. This cost is
the injection cost of the cheapest generator that has capacity for possible
delivery to the destination.

3. Paths for which the entry cost plus the transmission cost are higher than
105% of the destination market price are rejected as being uneconomic.

4.To the extent remaining paths are not simultaneously feasible (because,
for example, suppliers can seek to use the paths in both directions), a
series of decision rules for determining the direction of the line are
undertaken (in the following order):

o Instructions can be manually input as to the chosen direction of a line.

o Merger-case decisions should be consistent with base-case decisions.

o The direction of the line as determined in an economic allocation of
  available transmission is applied.

o The direction heading toward a destination market, if it is clear, is
  chosen.

o The direction that retains the maximum potential volume-weighted flow on
  the line (calculated from the paths that depend on this line) is
  chosen.

o The direction on which the maximum number of economic paths depend is
  chosen. If these other options fail to reach a feasible solution,
  manual input will be required.

5. Proration begins at nodes furthest from the destination market (where
only exports, and no imports are being attempted). Suppliers at these nodes
are assigned a "share" equal to their maximum economic supply capability.

6. Proration continues at the next set of nodes, that should consist only of
nodes with inflows from "resolved" nodes from step 5. Suppliers at these
nodes are assigned a "share" equal to their maximum economic supply
capability. Suppliers from the "resolved" nodes have their shares scaled
down to match the transmission capacity into the node.

7. To the extent an iteration of the algorithm does not resolve any
additional nodes and the destination market has not yet been reached (i.e.,
a loop is detected), flow is disallowed from any unresolved node to the
furthest and smallest node affected by a loop.

8. The proration has been completed when the destination market node has
been resolved. At that point, the "shares" at the destination market
represent the prorated shares of deliverable energy.

9. Injections for each supplier are "capped" at the calculated shares, and
these injections are then checked for economic feasibility. While suppliers
need not deliver their energy to the destination in exactly the way that
their share was calculated, the solution is still both economically and
physically feasible. The final solution represents the least-cost method of
delivering these supplies.

CASm IMPLEMENTATION

CASm_v87 has been implemented using GAMS (Generalized Algebraic Modeling
System), release 2.5. GAMS is a programming language which supports both
data manipulation and calls to many mainstream mathematical modeling
systems. The linear programming problems generated by CASm are solved by
BDMLP. The path enumeration program has been written in Microsoft Visual
C++ version 5.

System lambda data from 1999 FERC Form 714 filings. Hours aggregated based on
IPL's load. Power Markets Week data is for CY1999 ("Index price"). For some
regions, PMW reports both a peak and off-peak value, in others just a peak
value. NA refers to regions where PMW reports only a peak price.

Note: Illinois Power is not shown since they did not file lambda data in 1999.

                    AGREEMENT AND PLAN OF SHARE EXCHANGE

            AGREEMENT AND PLAN OF SHARE EXCHANGE, dated as of
July 15, 2000, by and between The AES Corporation, a Delaware corporation
("Parent"), and IPALCO Enterprises, Inc., an Indiana corporation (the
"Company").

                            W I T N E S S E T H:

            WHEREAS, the respective Boards of Directors of Parent and the
Company have approved the acquisition of the Company by Parent on the terms
and subject to the conditions set forth in this Agreement;

            WHEREAS, the respective Boards of Directors of Parent and the
Company have approved the mandatory share exchange (the "Exchange") whereby
all of the issued and outstanding shares of Common Stock, no par value, of
the Company ("Company Common Stock") shall be acquired by Parent in
exchange for shares of validly issued, fully paid and nonassessable common
stock, par value $0.01 per share, of Parent ("Parent Common Stock") on the
terms and subject to the conditions set forth in this Agreement;

            WHEREAS, for accounting purposes, it is intended that the
transactions contemplated hereby be accounted for as a pooling-of-interests
under United States generally accepted accounting principles ("GAAP") and
the rules and regulations of the Securities and Exchange Commission
("SEC");

            WHEREAS, for United States federal income tax purposes, it is
intended that the transactions contemplated hereby qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code"), and that this Agreement shall be,
and is hereby, adopted as a plan of reorganization for purposes of Section
368 of the Code; and

            WHEREAS, Parent and the Company desire to make certain
representations, warranties, covenants and agreements in connection with
the Exchange and also to prescribe various conditions to the Exchange.

            NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements contained herein the
parties hereto agree as follows:


                                 ARTICLE I

                                THE EXCHANGE

            Section 1.1 The Exchange. On the terms and subject to the
conditions set forth in this Agreement, and in accordance with the Business
Corporation Law of the State of Indiana (the "BCL"), at the Effective Time
(as defined in Section 1.3), (i) Parent and the Company shall effect the
Exchange, and (ii) the Company shall become a wholly owned Subsidiary of
Parent.

            Section 1.2 Closing. The closing (the "Closing") of the
Exchange shall take place at the offices of Skadden, Arps, Slate, Meagher &
Flom LLP, 1440 New York Avenue, N.W., Washington, D.C. 20005 at 10:00 a.m.,
local time, on or prior to the fifth business day following the
satisfaction (or, to the extent permitted by Law (as defined in Section
3.4), waiver by all parties) of the conditions set forth in Section 7.1,
or, if on such day any condition set forth in Section 7.2 or 7.3 has not
been satisfied (or, to the extent permitted by Law, waived by the party or
parties entitled to the benefits thereof), as soon as practicable after all
the conditions set forth in Article VII have been satisfied (or, to the
extent permitted by Law, waived by the parties entitled to the benefits
thereof), or at such other place, time and date as shall be agreed in
writing between Parent and the Company. The date on which the Closing
occurs is referred to in this Agreement as the "Closing Date."

            Section 1.3 Effective Time. Prior to the Closing, Parent and
the Company shall prepare and, on the Closing Date or as soon as
practicable thereafter, shall file with the Secretary of State of the State
of Indiana, the articles of share exchange or other appropriate documents
(in any such case, the "Articles of Share Exchange") executed in accordance
with the relevant provisions of the BCL and shall make all other filings or
recordings required under the BCL. The Exchange shall become effective at
such time as the Articles of Share Exchange are duly filed with the
Secretary of State of the State of Indiana, or at such other time as Parent
and the Company shall agree and specify in the Articles of Share Exchange
(the time the Exchange becomes effective being the "Effective Time").

            Section 1.4  Effects.

            (a) The Exchange shall have the effects set forth in Section
23-1-40-6 of the BCL.

            (b) The parties hereto acknowledge and agree that the
consummation of the Exchange and no other event in connection with this
Agreement constitutes "an acquisition of control" or a "change in control."

            Section 1.5 Articles of Incorporation and By-laws. The Articles
of Incorporation and By-laws of the Company as in effect immediately prior
to the Effective Time shall continue to be the Articles of Incorporation
and By-laws of the Company until thereafter changed or amended as provided
therein or by applicable Law.

            Section 1.6 Directors. All of the directors of the Company as
of immediately prior to the Effective Time shall resign effective as of the
Effective Time and Parent shall thereafter have the right to appoint
directors in accordance with the BCL.


                                 ARTICLE II

                     EFFECT ON THE CAPITAL STOCK OF THE
             CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

            Section 2.1 Effect on Capital Stock. At the Effective Time, by
virtue of the Exchange and without any action on the part of the holder of
any shares of Company Common Stock:

            (a) Cancellation of Treasury Stock. Each share of Company
Common Stock that is owned immediately prior to the Effective Time by the
Company or Parent shall automatically be canceled and retired and shall
cease to exist, and no cash or other consideration shall be delivered or
deliverable in exchange therefor.

            (b) Exchange of Company Common Stock. Subject to Section
2.1(a), each issued share of Company Common Stock outstanding immediately
prior to the Effective Time shall be exchanged for such number (the
"Exchange Ratio") of shares of Parent Common Stock calculated as follows:

                  (i) if the Average Trading Price (as defined below) of a
      share of Parent Common Stock is greater than or equal to $31.50, the
      Exchange Ratio shall equal a quotient (rounded to the third decimal
      place) determined by dividing (x) $25.00 (the "Per Share Amount"),
      subject to adjustment in accordance with Section 2.2 (as adjusted,
      the "Adjusted Per Share Amount"), by (y) the Average Trading Price of
      a share of Parent Common Stock; and

                  (ii) if the Average Trading Price of a share of Parent
      Common Stock is less than $31.50, the Exchange Ratio shall equal a
      quotient (rounded to the third decimal place) determined by dividing
      (x) the Per Share Amount or Adjusted Per Share Amount, as applicable,
      by (y) $31.50.

      "Average Trading Price" shall be equal to the average of the daily
closing prices per share of Parent Common Stock on the New York Stock
Exchange ("NYSE") Composite Transactions Reporting System, as reported in
The Wall Street Journal, for the twenty trading days ending on the date
immediately prior to the fifth full NYSE trading day immediately preceding
the Closing Date.

      The Exchange Ratio shall be subject to appropriate adjustment in the
event of any stock split, stock dividend or recapitalization after the date
of this Agreement applicable to shares of Parent Common Stock or Company
Common Stock. The number of shares of Parent Common Stock issuable by
Parent upon consummation of the Exchange in accordance with this Article
II, together with any cash payable in lieu of fractional shares in
accordance with Section 2.3(h), is referred to collectively as the
"Exchange Consideration."

            (c) Parent shall acquire and become the sole holder and owner
of each issued and outstanding share of Company Common Stock so exchanged.

            Section 2.2  Per Share Amount Adjustments.

            (a) In the event the Closing occurs after the Trigger Date (as
defined below), then the Per Share Amount shall be increased by an amount
equal to $0.00411 per share per day from the date after the Trigger Date
through the earliest of (but not including) (x) the Closing Date and (y)
the Termination Date (as defined in Section 8.1(b)(i)). In addition, on the
Trigger Date, if the Closing has not yet occurred, the Per Share Amount
shall be increased, on a one-time basis, by an amount equal to $0.15 per
share.

            (b) For purposes of this Agreement, the "Trigger Date" shall be
the latest of (x) March 31, 2001, (y) the date which is 30 days after the
Indiana Certification (as defined in Section 6.3(a)) has been issued and
(z) the date on which all the conditions set forth in Section 7.1 and in
Sections 7.2(c), 7.2(d), 7.2(h), and clauses (i), (ii) and (iii) of Section
7.2(i) have been satisfied or waived by Parent and the conditions set forth
in Sections 7.2(a) and 7.2(b) would have been satisfied if the Closing had
occurred on such date. Notwithstanding the foregoing the Trigger Date shall
not occur in the event the condition set forth in Section 7.1(d) is not
satisfied until following the satisfaction of the condition set forth in
Section 7.2(e). For purposes of determining the Trigger Date, the Company
shall deliver, as promptly as reasonably practicable, a certificate of an
executive officer of the Company setting forth the date of the proposed
Trigger Date. In the event Parent disagrees with the date set forth in such
certificate, Parent shall notify the Company in writing within five
business days of receipt of such certificate, specifying the reason for the
nature of such disagreement. The parties agree to negotiate in good faith
to promptly resolve any differences with respect to the date of the Trigger
Date as set forth in the certificate of the Company's executive officer.

            Section 2.3 Exchange of Certificates.

            (a) Exchange Agent. Prior to the Effective Time, Parent shall
select a bank or trust company, which shall be reasonably satisfactory to
the Company, to act as exchange agent (the "Exchange Agent") for exchange
in accordance with this Article II of the Exchange Consideration upon
surrender of certificates representing Company Common Stock. Immediately
prior to or at the Effective Time, Parent shall deposit with the Exchange
Agent, for the benefit of the holders of shares of Company Common Stock,
for exchange in accordance with this Article II, (i) certificates
representing the shares of Parent Common Stock issuable upon consummation
of the Exchange and (ii) cash funds estimated to be sufficient to make
payment for any fractional shares pursuant to Section 2.3(h) (such shares
of Parent Common Stock and cash funds together being hereinafter referred
to as the "Exchange Fund").

            (b) Exchange Procedure. As soon as reasonably practicable after
the Effective Time, the Exchange Agent shall mail to each holder of record
of a certificate or certificates (the "Certificates") that immediately
prior to the Effective Time represented outstanding shares of Company
Common Stock whose shares were exchanged for the Exchange Consideration
pursuant to Section 2.1, (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent and shall be in such form and have such other provisions as
Parent may reasonably specify) and (ii) instructions for use in effecting
the surrender of the Certificates in exchange for the Exchange
Consideration. Upon surrender of a Certificate for cancellation to the
Exchange Agent, together with such letter of transmittal, duly executed,
and such other documents as may reasonably be required by the Exchange
Agent, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate or certificates representing that whole
number of shares of Parent Common Stock which such holder has the right to
receive pursuant to the provisions of this Article II, and the Certificate
so surrendered shall forthwith be canceled. In the event of a transfer of
ownership of Company Common Stock that is not registered in the transfer
records of the Company, exchange may be made to a person other than the
person in whose name the Certificate so surrendered is registered, if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and shall be accompanied by evidence satisfactory to the Exchange
Agent that any transfer or other Taxes (as defined in Section 3.11(a))
required by reason of such payment in a name other than that of the
registered holder of such Certificate or instrument either has been paid or
is not payable. Until surrendered as contemplated by this Section 2.3, each
Certificate shall be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender the Exchange
Consideration.

            (c) No Further Ownership Rights in Company Common Stock. The
Exchange Consideration delivered in accordance with the terms of this
Article II upon exchange of any shares of Company Common Stock shall be
deemed to have been delivered in full satisfaction of all rights pertaining
to such shares of Company Common Stock, subject, however, to the Company's
obligation to pay any dividends or make any other distributions with a
record date prior to the Effective Time that may have been declared or made
by the Company on such shares of Company Common Stock in accordance with
the terms of this Agreement or prior to the date of this Agreement and
which remain unpaid at the Effective Time. At the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers on the stock transfer books of the Company of
shares of Company Common Stock that were outstanding immediately prior to
the Effective Time. If, after the Effective Time, any certificates formerly
representing shares of Company Common Stock are presented to the Company or
the Exchange Agent for any reason, they shall be canceled and exchanged as
provided in this Article II.

            (d) Termination of Exchange Fund. Promptly after the date which
is six months after the Effective Time, the Exchange Agent shall deliver to
Parent certificates, cash and other documents in its possession relating to
the transactions contemplated hereby, and the Exchange Agent's duties shall
terminate, and any holder of Company Common Stock who has not theretofore
complied with this Article II shall thereafter look only to the Company
(subject to applicable abandoned property, escheat and similar laws) for
payment of its claim for the Exchange Consideration but only as general
creditors thereof.

            (e) No Liability. None of Parent, the Company or the Exchange
Agent shall be liable to any person in respect of any shares or funds
delivered to a public official pursuant to any applicable abandoned
property, escheat or similar Law.

            (f) Investment of Exchange Fund. The Exchange Agent shall
invest any cash included in the Exchange Fund, as directed by Parent, on a
daily basis. Any interest and other income resulting from such investments
shall be paid to Parent.

            (g)   Withholding Rights.  Parent, the Company and the Exchange
Agent shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to any holder of shares of
Company Common Stock such amounts as Parent, the Company or the Exchange
Agent is required to deduct and withhold with respect to the making of such
payment under the Code or any provision of state, local or foreign Tax law.
To the extent that amounts are so withheld and paid over to the appropriate
Taxing Authority by Parent, the Company or the Exchange Agent, such
withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the holder of the shares of Company Common Stock in
respect of which such deduction and withholding was made by Parent, the
Company or the Exchange Agent.

            (h) No Fractional Shares. No fractional shares of Parent Common
Stock will be issued to holders of Company Common Stock upon surrender of
shares of Company Common Stock in exchange for the Exchange Consideration
and any such fractional share interests shall not entitle the owner thereof
to vote or to any other rights of a holder of Company Common Stock. In lieu
thereof, Parent shall pay to such holders otherwise entitled to a
fractional share cash in an amount equal to the product of such fraction
and the Average Trading Price. For purposes of this Section 2.3(h), all
fractional shares to which a single record holder would be entitled shall
be aggregated.

            Section 2.4  Stock Option Plans.

            (a) Immediately prior to the Effective Time, the Company shall
have adopted such resolutions, taken such actions and obtained any
necessary consents (including the consent of individual option holders, if
necessary) as may be required to provide that each option to acquire shares
of Company Common Stock (the "Company Stock Options") shall be assumed by
Parent as of the Effective Time and shall thereafter be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Company Stock Option immediately prior to the
Effective Time, the number (rounded to the nearest whole number) of shares
of Parent Common Stock determined by multiplying the number of shares of
Company Common Stock subject to such Company Stock Option immediately prior
to the Effective Time by the Exchange Ratio, at a price per share (rounded
to the nearest whole cent) equal to the exercise price per share of Company
Common Stock otherwise purchasable pursuant to such Company Stock Option
divided by the Exchange Ratio; provided, however, that with respect to any
Company Stock Option that is an incentive stock option within the meaning
of the Code, such substitution shall be effected in accordance with Section
424(a) of the Code.

            (b) The Company and, to the extent applicable, Parent shall
take all actions necessary (including obtaining the consent of individual
award holders, if necessary) to provide that (i) each award or account
(including each share of restricted or performance stock granted under the
Company Option Plans, stock equivalents and stock units, but excluding
Company Stock Options) outstanding as of the date of this Agreement (a
"Company Stock Award") that has been established, made or granted under any
employee incentive or benefit plans, programs or arrangements and
non-employee director plans maintained by the Company on or prior to the
date hereof which provide for grants of equity-based awards or equity-based
accounts shall be amended or converted into a similar instrument of and
assumed by Parent as of the Effective Time in accordance with its terms and
conditions as in effect immediately prior to the Effective Time, in each
case with such adjustments to the terms and conditions of such Company
Stock Awards as are appropriate to preserve the value inherent in such
Company Stock Awards with no detrimental effects on the holders thereof,
and (ii) any holder of a Company Stock Award may elect to authorize the
Company to retain a number of shares of Company Common Stock from such
grant having an aggregate fair market value equal to any withholding taxes
applicable to the vesting of such grant, in lieu of the payment of such
amount in cash.

            (c) Except as otherwise agreed to by the parties, (i) the
Company shall take all actions necessary to provide that the provisions in
any other plan, program or arrangement providing for the issuance or grant
by the Company or any of its Subsidiaries of any interest in respect of the
capital stock of the Company or any of its Subsidiaries shall be deleted,
and (ii) the Company shall ensure that following the Effective Time no
holder of Company Stock Options or any participant in the Company Option
Plans or any other such plan, program or arrangement providing for the
issuance or grant by the Company or any of its Subsidiaries of any interest
in respect of the capital stock of the Company or any of its Subsidiaries
shall have any right thereunder to acquire any equity securities of the
Company or any Subsidiary thereof unless otherwise agreed by Parent and
such holder or participant.

            (d) Parent shall take all actions necessary to reserve for
issuance, from and after the Effective Time, a sufficient number of shares
of Parent Common Stock for delivery pursuant to the terms set forth in this
Section 2.4. On or before the Effective Time, Parent shall cause to be
filed with the SEC a registration statement on an appropriate form or a
post-effective amendment to a previously filed registration statement under
the Securities Act of 1933, as amended (the "Securities Act"), with respect
to shares of Parent Common Stock subject to options and other equity-based
awards issued pursuant to this Section 2.4, and shall use reasonable
efforts to maintain the current status of the prospectus contained therein,
as well as to comply with any applicable state securities or "blue sky"
laws, for so long as such options or other equity-based awards remain
outstanding.

            (e) By adopting or approving this Agreement, the Board of
Directors of the Company (the "Company Board") shall be deemed to have
approved and authorized, and the shareholders of the Company shall be
deemed to have approved and ratified, each and every amendment to any of
the Company Option Plans, Company Stock Options or Company Stock Awards as
the officers of the Company may deem necessary or appropriate to give
effect to the provisions of Sections 2.4(a) and 2.4(b).


                                ARTICLE III

               REPRESENTATIONS AND WARRANTIES OF THE COMPANY

            The Company represents and warrants to Parent that except as
set forth in the Company SEC Documents (as defined in Section 3.5) filed
and publicly available prior to the date of this Agreement and except as
set forth in the disclosure schedule delivered by the Company to Parent
concurrent with the execution of this Agreement (the "Company Disclosure
Schedule"):

            Section 3.1  Organization, Standing and Power.

            (a) Each of the Company, each Subsidiary of the Company (a
"Company Subsidiary") and each Company Joint Venture (as defined in Section
9.3) is a corporation or other entity duly organized, validly existing and,
if applicable, in good standing under the laws of the jurisdiction in which
it is incorporated or organized and has full corporate power and authority
and has been duly authorized by all necessary approvals and orders,
including possessing all governmental franchises, licenses, permits,
authorizations and approvals necessary to enable it to own, operate, lease
or otherwise hold its properties and assets and to conduct its businesses
as presently conducted, other than such franchises, licenses, permits,
authorizations and approvals the lack of which, individually or in the
aggregate, have not had and would not have a Company Material Adverse
Effect (as defined below). The term "Company Material Adverse Effect" means
an event, change, cause or effect which is materially adverse to the
business, operations, properties, assets, liabilities, prospects, condition
(financial or otherwise) or results of operations of the Company and its
Subsidiaries, taken as a whole or of the consummation of the transactions
contemplated hereby. The Company and each Company Subsidiary is duly
qualified and, if applicable, in good standing, to do business in each
jurisdiction where the nature of its business or their ownership or leasing
of its assets and properties make such qualification necessary, other than
the failure to so qualify and be in good standing, which together with all
other such failures, has not had and would not have a Company Material
Adverse Effect. The Company has made available to Parent true and complete
copies of the articles of incorporation of the Company, as amended to the
date of this Agreement (as so amended, the "Company Charter"), and the
By-laws of the Company, as amended to the date of this Agreement (as so
amended, the "Company Bylaws"), and the comparable charter and
organizational documents of each Company Subsidiary, in each case as
amended through the date of this Agreement.

            (b) Section 3.1(b) of the Company Disclosure Schedule sets
forth a list of all the Company Subsidiaries and the Company Joint
Ventures, as of the date of this Agreement, including the name of each such
entity, a brief description of the principal line or lines of business
conducted by each such entity and the interest of the Company and the
Company Subsidiaries therein and the authorized, issued and outstanding
capital stock of each of the Company Subsidiaries. The Company is a
"holding company" (as defined in the Public Utility Holding Company Act of
1935, as amended ("PUHCA")) exempt from all provisions (other than Section
9(a)(2)) of PUHCA, pursuant to Section 3(a)(1) of PUHCA in accordance with
Rule 2 under PUHCA. The Company is not a "public utility company" within
the meaning of Section 2(a)(5) of PUHCA. With the exception of Entity I, no
Company Subsidiary or Company Joint Venture is a "holding company" or a
"public utility company" within the meaning of Sections 2(a)(7) and 2(a)(5)
of PUHCA, respectively, nor, except with respect to their relationship with
the Company, are any of such entities an "affiliate" or a "subsidiary
company" of a holding company within the meaning of Sections 2(a)(11) and
2(a)(8) of PUHCA, respectively. All of the issued and outstanding shares of
capital stock of each Company Subsidiary are validly issued, fully paid,
nonassessable and free of preemptive rights and to the extent owned,
directly or indirectly, by the Company, are owned free and clear of any
liens, claims, encumbrances, security interests, charges and options of any
nature whatsoever ("Liens"), and there are no outstanding subscriptions,
options, calls, contracts, voting trusts, proxies or other pledges,
security interests, commitments, understandings, restrictions,
arrangements, rights or warrants (including any right of conversion or
exchange under any outstanding security, instrument or other agreement),
obligating the Company or any Company Subsidiary to issue, deliver or sell,
pledge, grant a security interest on or encumber, or cause to be issued,
delivered or sold, pledged or encumbered or a security interest to be
granted on, shares of capital stock of any Company Subsidiary or obligating
the Company or any Company Subsidiary to grant, extend or enter into any
such agreement or commitment.

            Section 3.2  Capital Structure.

            (a) The authorized capital stock of the Company consists solely
of 290,000,000 shares of Company Common Stock, no par value, and no shares
of preferred stock. As of the date of this Agreement, 85,722,469 shares of
Company Common Stock were issued and outstanding, 31,056,356 shares were
held in the treasury of the Company, and the only shares reserved for

Subsidiary or any Voting Company Debt or (ii) obligating the Company or any
Company Subsidiary to issue, grant, extend or enter into any such option,

Effect.

            Section 3.5 SEC Documents. The filings required to be made by
the Company and the Company Subsidiaries under the Securities Act and the
Exchange Act, as the case may be, have been filed and complied, as of their

requirements of the Securities Act or the Exchange Act, as the case may be,

included in the Company SEC Documents complied as to form in all material
respects with applicable accounting requirements and the published rules
and regulations of the SEC with respect thereto, were prepared in
accordance with GAAP applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto) and fairly
presented the consolidated financial position of the Company and its
consolidated Subsidiaries as of the dates thereof and the consolidated
results of their operations and cash flows for the periods then ended

adjustments).

            Section 3.6 Absence of Certain Changes or Events. From December
31, 1999 to the date of this Agreement, the Company has conducted its

development that, individually or in the aggregate, has had or would have a

election with respect to Taxes by the Company or any of the Company
Subsidiaries or any settlement or compromise of any material Tax liability
or refund of the Company or any of the Company Subsidiaries, and (iii)

practices by the Company or any of the Company Subsidiaries, except insofar
as may have been required by a change in GAAP or SEC accounting regulations

            Section 3.7 Absence of Undisclosed Liabilities. Except for
liabilities, obligations or contingencies which would not, in the
aggregate, have a Company Material Adverse Effect, or which are accrued or
reserved against in the consolidated financial statements of the Company or

quarter ended March 31, 2000, or which were incurred after December 31,
1999 in the ordinary course of business, neither the Company nor any
Company Subsidiary, nor, to the knowledge of Company, any Company Joint
Venture, has any liabilities or obligations (whether absolute, accrued,
contingent or otherwise and including margin loans) which are material to
the Company and the Company Subsidiaries taken as a whole.

            Section 3.8 Litigation. As of the date of this Agreement, there
is no suit, claim, action, investigation or proceeding pending, or to the
knowledge of the Company threatened, from any governmental authority,
including any regulatory body or commission, against the Company or any
Company Subsidiary that, individually or in the aggregate, has had or would
have a Company Material Adverse Effect, nor is there any Judgment of any
governmental authority or any arbitrator outstanding against the Company or
any Company Subsidiary that has had or would have a Company Material
Adverse Effect.

            Section 3.9 Compliance with Applicable Laws. Neither the
Company nor any of the Company Subsidiaries is in violation of, or to the
knowledge of the Company under investigation with respect to any violation
of, or has been given written notice of or been formally charged with any
violation of, any law, statute, order, rule, regulation, ordinance or
judgment, permit, license, concession or franchise of any Governmental
Entity, including PUHCA, the Power Act and applicable state, municipal,
local and other laws, including franchise and public utility laws and
regulations, and all documents, exhibits, amendments and supplements
pertaining thereto have been filed by the Company and the Company
Subsidiaries with the SEC, the FERC and the appropriate Indiana or other
appropriate Governmental Entities, except for violations or failures to
comply with Environmental Laws (which are the subject of Section 3.13) or
with respect to Taxes (which are the subject of Section 3.11) and except
for violations and failures to file which individually or in the aggregate
have not had and would not have a Company Material Adverse Effect. The
Company and each of the Company Subsidiaries is not in breach or violation
of or in default in the performance or observance of any term or provision
of, and no event has occurred which, with lapse of time or action by a
third party, could result in a default by the Company or the Company
Subsidiary under (i) the Company Charter, the Company By-laws or other
organizational documents or (ii) any contract, commitment, agreement,
indenture, mortgage, loan agreement, note, lease, bond, license, approval
or other instrument to which it is a party or by which the Company or the
Company Subsidiary is bound or to which any of its property is subject,

defaults which individually or in the aggregate have not had and would not
have a Company Material Adverse Effect.

Agreement) by reason of this Agreement or the Exchange, (B) a "Distribution
Date" (as defined in the Company Rights Agreement) shall not occur by
reason of this Agreement or the Exchange, and (C) all outstanding Company

            Section 3.11 Taxes.

            (a) For purposes of this Agreement: (i) "Taxes" (including,
with correlative meaning, the word "Tax") shall include any and all (x)

described in clause (x) as a result of being a member of an affiliated,
consolidated, combined or unitary group, and (z) liability for the payment

certificate, statement or other document (including any related or
supporting information) required to be filed with or supplied to, or, where
none is required to be filed with or supplied to a Taxing Authority, the
statement or other document issued by, a Taxing Authority in connection
with any Tax (including any combined, consolidated or unitary returns for
any group of entities that includes the Company or any Company Subsidiary).

            (b) Filing of Timely Tax Returns. The Company and each of the
Company Subsidiaries have timely filed (or there has been timely filed on
their behalf) all Tax Returns required to be filed by or on behalf of each
of them under applicable law and all such Tax Returns were and are in all
material respects true, complete and correct, except to the extent that any
failure to file or any inaccuracies in any filed Tax Returns, individually
or in the aggregate, have not had and would not have a Company Material
Adverse Effect.

            (c) Payment of Taxes. The Company and each of the Company
Subsidiaries have, within the time and in the manner prescribed by law,
paid or adequately reserved for all Taxes that are due and payable from
them, except to the extent that any failure to pay or reserve, individually
or in the aggregate, has not had and would not have a Company Material
Adverse Effect.

            (d) Tax Reserves. The accrual for Taxes on the most recent
Company SEC Documents reflects an adequate reserve in accordance with GAAP
for all Taxes payable by the Company and the Company Subsidiaries for all
Tax periods (and portions thereof) accrued on or before the date of such
financial statements except to the extent that any failure to have an
adequate reserve, individually or in the aggregate, has not had and would
not have a Company Material Adverse Effect.

            (e) Tax Liens. There are no Tax liens upon the assets,
properties or business of the Company or any of the Company Subsidiaries
except liens for Taxes not yet due or being contested in good faith through
appropriate proceedings and for which adequate reserves have been

Material Adverse Effect.

Subsidiaries have complied in all material respects with the provisions of
the Code and all other applicable laws relating to the payment and
withholding of Taxes, including, the withholding and reporting requirements
under Code Sections 1441 through 1464, 3401 through 3406 and 6041 through
6049, as well as similar provisions under any other laws, and have, within
the time and in the manner prescribed by law, withheld from employee wages
and paid over to the proper Taxing Authorities all amounts required, except
to the extent that a failure to comply, withhold or pay, individually or in
the aggregate, has not had and would not have a Company Material Adverse
Effect.

            (g) Extensions of Time for Filing Tax Returns. Neither the
Company nor any of the Company Subsidiaries has requested any extension of
time within which to file any Tax Return, which Tax Return has not since
been timely filed unless such extension has not expired.

            (h) Waivers of Statute of Limitations. Neither the Company nor
any of the Company Subsidiaries has executed any outstanding waivers or
comparable consents regarding the application of the statute of limitations
with respect to any Taxes or Tax Returns, except for waivers or comparable
consents for any Taxes or Tax Returns that, individually or in the
aggregate, have not had and would not have a Company Material Adverse
Effect.

            (i) Expiration of Statute of Limitations. The statutes of
limitations for the assessment of all Taxes with respect to all Tax Returns
of the Company and the Company Subsidiaries for all Tax periods have
expired. To the knowledge of the Company, no deficiency for any Taxes has
been proposed, asserted or assessed against the Company or any of the
Company Subsidiaries that has not been resolved and paid in full, except
for any deficiency that, individually or in the aggregate, has not had and
would not have a Company Material Adverse Effect.

            (j) Audit, Administrative and Court Proceedings. No audits or
other proceedings by any Taxing Authority are presently pending, or to the
knowledge of the Company, have been threatened with regard to any Taxes or
Tax Returns of the Company or any of the Company Subsidiaries that are not
adequately reserved for except to the extent that any audits or other
proceedings, individually or in the aggregate, have not had and would not
have a Company Material Adverse Effect.

            (k)   Consolidated Tax Returns.  Neither the Company nor any of
the Company Subsidiaries has ever been a member of an affiliated group of
corporations (within the meaning of Code Section 1504(a)) filing
consolidated Tax Returns, other than the affiliated group of which the
Company is the common parent.

            (l) Code Section 355. Neither the Company nor any of the
Company Subsidiaries has constituted either a "distributing corporation" or
a "controlled corporation" in a distribution of stock outside of the
affiliated group of which the Company is the common parent qualifying or
intended to qualify for tax-free treatment under Section 355(a) of the Code
(A) in the two years prior to the date of this Agreement or (B) in a
distribution that could otherwise constitute part of a "plan" or "series of
related transactions" (within the meaning of Section 355(e) of the Code) in
conjunction with the Exchange.

            (m) Availability of Tax Returns. Upon request the Company has
made available to Parent complete and accurate copies of (i) all Tax
Returns for open years, and any amendments thereto, filed by or on behalf
of the Company or any of the Company Subsidiaries, (ii) all audit reports
or written proposed adjustments (whether formal or informal) received from
any Taxing Authority relating to any Tax Return filed by or on behalf of
the Company or any of the Company Subsidiaries, and (iii) any Tax ruling or
request for a Tax ruling applicable to the Company or any of the Company
Subsidiaries entered into by the Company or any of the Company
Subsidiaries.

            (n) Tax Treatment. As of the date of this Agreement, neither
the Company nor any of the Company Subsidiaries knows of any fact that is
reasonably likely to prevent the Exchange, if consummated as of the date of
this Agreement, from qualifying as a reorganization within the meaning of
Section 368(a) of the Code.

            Section 3.12 Employee Matters; ERISA.

            (a) Section 3.12(a) of the Company Disclosure Schedule contains
a true and complete list of each deferred compensation and each bonus or
other incentive compensation, stock purchase, stock option and other equity
compensation plan, program, agreement or arrangement; each severance or
termination pay, medical, surgical, hospitalization, life insurance and
other "welfare" plan, fund or program (within the meaning of Section 3(1)
of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")); each profit-sharing, stock bonus or other "pension" plan, fund
or program (within the meaning of Section 3(2) of ERISA); each employment,
termination or severance agreement; and each other employee benefit plan,
fund, program, agreement or arrangement, in each case, that is sponsored,
maintained or contributed to or required to be contributed to by the
Company or a Company Subsidiary or by any trade or business, whether or not
incorporated (an "ERISA Affiliate"), that together with the Company or a
Company Subsidiary would be deemed a "single employer" within the meaning
of Section 4001(b) of ERISA, or to which the Company or a Company
Subsidiary or an ERISA Affiliate is party, whether written or oral, for the
benefit of any employee or former employee of the Company or any Company
Subsidiary (the "Company Benefit Plans"). Section 3.12(a) of the Company
Disclosure Schedule identifies each of the Plans of the Company or any
Company Subsidiary or any ERISA Affiliate (a "Title IV Plan") that is
subject to Section 302 or Title IV of ERISA or Section 412 of the Code.
Neither the Company, any Company Subsidiary nor any ERISA Affiliate has any
commitment or formal plan, whether legally binding or not, to create any
additional employee benefit plan or modify or change any existing Company
Benefit Plan that would affect any employee or former employee of the
Company or any Company Subsidiary.

            (b) With respect to each Company Benefit Plan, the Company has
heretofore delivered or made available to Parent true and complete copies
of each of the following documents:

                  (i)  a copy of the Company Benefit Plan and any
      amendments thereto (or if the Company Benefit Plan is not a written
      plan, a description thereof);

                  (ii) a copy of the two most recent annual reports and
      actuarial reports, if required under ERISA, and the most recent
      report prepared with respect thereto in accordance with Statement of
      Financial Accounting Standards No. 87;

                  (iii)  a copy of the most recent Summary Plan Description
      required under ERISA with respect thereto;

                  (iv) if the Company Benefit Plan is funded through a
      trust or any third party funding vehicle, a copy of the trust or
      other funding agreement and the latest financial statements thereof;
      and

                  (v) the most recent determination letter received from
      the IRS with respect to each Company Benefit Plan intended to qualify
      under Section 401 of the Code.

            (c) No material liability under Title IV or Section 302 of
ERISA has been incurred by the Company, a Company Subsidiary or any ERISA
Affiliate that has not been satisfied in full, and to the knowledge of the
Company no condition exists that presents a material risk to the Company, a
Company Subsidiary or any ERISA Affiliate of incurring any such liability,
other than liability for premiums due the Pension Benefit Guaranty
Corporation ("PBGC") (which premiums have been paid when due). Insofar as
the representation made in this Section 3.12(c) applies to Sections 4064,
4069 or 4204 of Title IV of ERISA, it is made with respect to any employee
benefit plan, program, agreement or arrangement subject to Title IV of
ERISA to which the Company, a Company Subsidiary or any ERISA Affiliate
made, or was required to make, contributions during the eight-year period
ending on the last day of the most recent plan year ended prior to the
Effective Time.

            (d) The PBGC has not instituted proceedings to terminate any
Title IV Plan and to the knowledge of the Company no condition exists that
presents a material risk that such proceedings will be instituted.

            (e) With respect to each Title IV Plan, the present value of
accrued benefits under such plan, based upon the actuarial assumptions used
for funding purposes in the most recent actuarial report prepared by such
plan's actuary with respect to such plan did not exceed, as of its latest
valuation date, the then current value of the assets of such plan allocable
to such accrued benefits.

            (f) No Title IV Plan or any trust established thereunder has
incurred any "accumulated funding deficiency" (as defined in Section 302 of
ERISA and Section 412 of the Code), whether or not waived, as of the last
day of the most recent fiscal year of each Title IV Plan ended prior to the
Effective Time.

            (g) All contributions required to be made with respect to any
Company Benefit Plan on or prior to the Closing Date have been timely made
or are reflected on the balance sheet of the Company. There has been no
amendment to, written interpretation of or announcement (whether or not
written) by the Company, any Company Subsidiary, or any ERISA Affiliate
relating to, or change in employee participation or coverage under, any
Company Benefit Plan that would increase materially the expense of
maintaining such Company Benefit Plan above the level or expense incurred
in respect thereof for the most recent fiscal year ended prior to the date
hereof.

            (h) No Title IV Plan is a "multiemployer pension plan," as
defined in Section 3(37) of ERISA, nor is any Title IV Plan a plan
described in Section 4063(a) of ERISA. If any Title IV Plan is a
"multiemployer pension plan," except as it has not had and would not have a
Company Material Adverse Effect, (i) neither the Company, a Company
Subsidiary nor any ERISA Affiliate has made or suffered a "complete
withdrawal" or a "partial withdrawal," as such terms are respectively
defined in Sections 4203 and 4205 of ERISA (or any liability resulting
therefrom has been satisfied in full), (ii) no event has occurred that
presents a material risk of a partial withdrawal, (iii) neither the
Company, a Company Subsidiary nor any ERISA Affiliate has any contingent
liability under Section 4204 of ERISA, and (iv) no circumstances exist that
present a material risk that any such plan will go into reorganization. If
any Title IV Plan is a "multiemployer pension plan," the aggregate
withdrawal liability of the Company, the Company Subsidiaries and their
ERISA Affiliates, computed as if a complete withdrawal by the Company, the
Company Subsidiaries and the ERISA Affiliates had occurred under each such
Plan on the date hereof, would not cause a Company Material Adverse Effect.

            (i) Neither the Company or any Company Subsidiary, any ERISA
Affiliate, any Company Benefit Plan, any trust created thereunder, nor any
trustee or administrator thereof has engaged in a transaction in connection
with which the Company or any Company Subsidiary, any Company Benefit Plan,
any such trust, or any trustee or administrator thereof, or any party
dealing with any Company Benefit Plan or any such trust would be subject to
either a material civil penalty assessed pursuant to Section 409 or 502(i)
of ERISA or a material tax imposed pursuant to Section 4975 or 4976 of the
Code.

            (j) Each Company Benefit Plan has been operated and
administered in all material respects in accordance with its terms and
applicable law, including ERISA and the Code, other than any noncompliance
that has not had and would not have a Company Material Adverse Effect.

            (k) Each Company Benefit Plan intended to be "qualified" within
the meaning of Section 401(a) of the Code has received a determination
letter from the IRS to the effect that it is so qualified and the trusts
maintained thereunder are exempt from taxation under Section 501(a) of the
Code. Each Company Benefit Plan intended to satisfy the requirements of
Section 501(c)(9) has satisfied such requirements.

            (l)   No Company Benefit Plan provides medical, surgical,
hospitalization, death or similar benefits (whether or not insured) for
employees or former employees of the Company or any Company Subsidiary for
periods extending beyond their retirement or other termination of service,
other than (i) coverage mandated by applicable law, (ii) death benefits
under any "pension plan," or (iii) benefits the full cost of which is borne
by the current or former employee (or his beneficiary). No condition exists
that would prevent the Company, any Company Subsidiary or any ERISA
Affiliate from amending or terminating any Company Benefit Plan providing
health or medical benefits in respect of any active employee of the Company
or any Company Subsidiary other than limitations imposed under the terms of
collective bargaining agreements.

            (m) No amounts payable under the Company Benefit Plans will
fail to be deductible for federal income tax purposes by virtue of Section
162(a)(1), 162(m) or 280G of the Code.

            (n) (i) (A) Section 3.12(n) of the Company Disclosure Schedule
sets forth the estimated maximum sum of the change in control payments and
entitlements (including accelerated vesting of the Company Stock Options or
other equity-based awards and increased benefits which are summarized)
which any employee, former employee, or other person who is party to a
Termination Benefits Agreement with the Company and its Subsidiaries, may
be entitled to receive now or in the future (including upon termination of
such person's employment) in connection with the Exchange or any of the
other transactions contemplated by this Agreement (whether alone or in
combination with some other event) based on the assumptions specified
therein; and (B) Section 3.12(n) of the Company Disclosure Schedule sets
forth, in the aggregate with respect to current or former employees or
officers of the Company, any Company Subsidiary or any ERISA Affiliate, the
estimated maximum sum of severance pay, unemployment compensation or any
other payment, acceleration in the time of payment or vesting, or increase
in the amount of compensation to which any such employees or officers will
become entitled upon the announcement or consummation of the transactions
contemplated by this Agreement, either alone or in combination with some
other event (other than the Company's involuntary termination of an
employee's employment after the Closing);

                  (ii) No payment (including any cash payment or
accelerated vesting of the Company Stock Options or other equity-based
awards) which would reasonably be expected to constitute "excess parachute
payments" within the meaning of Section 280G of the Code will be payable in
connection with the Exchange or the other transactions contemplated by this
Agreement (whether alone or in combination with some other event) to any
employee, former employee or other person who is or was providing services
to the Company or any of the Company Subsidiaries;

                  (iii) Neither the Company nor any of the Company
Subsidiaries is a party to any consulting contract with any person who
prior to entering into such contract was a director or officer of the
Company or any of the Company Subsidiaries or any similar material plan,
agreement, arrangement or understanding;

                  (iv) There have occurred no events since January 1, 1999,
that have had (or are reasonably expected to have in the future) a material
adverse effect on the funded status of the Employees' Retirement Plan of
Entity I;

                  (v) Section 3.12(n) of the Company Disclosure Schedule
sets forth the maximum amount of benefits that will become payable under
the Company's Unfunded Deferred Compensation Plan for Officers and
Directors by reason of the Exchange, or any of the other transactions
contemplated by this Agreement (whether alone or in combination with some
other event); and

                  (vi) Section 3.12(n) of the Company Disclosure Schedule
sets forth the maximum amount which represents the excess of (x) the total
amount of payments that would be due as of the date of this Agreement under
Section 4.01 of the Company's Supplemental Retirement Plan and Trust
Agreement for a Select Group of Management Employees assuming all
participants in such plan terminated employment as of the date of this
Agreement and elected immediate payment, in the form of a lump-sum
distribution (if the participant is eligible thereof) as of the date of
this Agreement over (y) the assets held as of the date of this Agreement in
the trust fund established under such plan, and the aggregate amount of any
Tax Distribution (as defined in such plan) that would be payable under
Section 4.03 of such plan if a contribution of $4,600,000 were made to such
plan as of the date of this Agreement (and allocated so as to fund benefits
under the plan on the basis described in the foregoing clause (n)(vii)(x))
would not exceed $8,100,000.

            (o) (i) There has been no material failure of a Company Benefit
Plan that is a group health plan (as defined in Section 5000(b)(1) of the
Code) to meet the requirements of Section 4980B(f) of the Code with respect
to a qualified beneficiary (as defined in Section 4980B(g) of the Code).
Neither the Company nor any Company Subsidiary or ERISA Affiliate has
contributed to a nonconforming group health plan (as defined in Section
5000(c) of the Code). Neither the Company nor any Company Subsidiary or
ERISA Affiliate has incurred a tax under Section 5000(e) of the Code which
is or could become a liability of the Company or a Company Subsidiary;

                  (ii) The Company will not be required after the Closing to
make any contribution to the IPALCO Enterprises, Inc. Voluntary Employees
Beneficiary Association;

                  (iii) After the Closing, the Company will have no
obligation (other than any it first establishes after the Closing or that
may be mandated pursuant to Part 6 of Subtitle B of Title I of ERISA) to
provide medical, surgical, hospitalization, death or similar benefits
(whether or not insured) for employees or former employees of the Company
or any Company Subsidiary for periods extending beyond their retirement or
other termination of service in excess of such benefits that can be funded
with assets held from time to time in the IPALCO Enterprises, Inc.
Voluntary Employees Beneficiary Association; and

                  (iv) The Company believes, after consultation with its
independent accountants and actuaries, that there is no material financial
statement effect with respect to the IPALCO Enterprises, Inc. Voluntary
Employees Beneficiary Association resulting from the attainment of the
Company Shareholder Approval beyond the contribution of $7.5 million within
thirty days of obtaining the Company Shareholder Approval.

            (p) To the knowledge of the Company, there are no pending,
threatened or anticipated claims by or on behalf of or against any Company
Benefit Plan, by any employee or beneficiary covered under any such Company
Benefit Plan, or otherwise involving any such Company Benefit Plan (other
than routine claims for benefits).

            (q) Labor Agreements. As of the date of this Agreement, neither
the Company nor any of the Company Subsidiaries is a party to or bound by
any collective bargaining agreement or other labor agreement with any union
or labor organization, or work rules or practices agreed to with any labor
organization or employee association applicable to employees of the Company
or any of the Company Subsidiaries. To the knowledge of the Company, as of
the date of this Agreement, there is no current union representation
question involving employees of the Company or any of the Company
Subsidiaries, nor does the Company know of any activity or proceeding of
any labor organization (or representative thereof) or employee group to
organize any such employees. There is no (i) grievance pending or, to the
knowledge of the Company, threatened, arising out of any collective
bargaining agreement or other grievance procedure, unfair labor practice,
employment discrimination or other investigation, charge or complaint
against the Company or any of the Company Subsidiaries, which has or would
have a Company Material Adverse Effect, (ii) strike, dispute, slowdown,
work stoppage or lockout pending, or, to the knowledge of the Company,
threatened, against or involving the Company or any of the Company
Subsidiaries which has or would have a Company Material Adverse Effect and
during the past five years there has not been any such action, (iii) as of
the date of this Agreement, proceeding, claim, suit, action or governmental
investigation pending or, to the knowledge of the Company, threatened, in
respect of which any director, officer, employee or agent of the Company or
any of the Company Subsidiaries is or may be entitled to claim
indemnification from the Company pursuant to the Company Charter or the
Company By-laws (or such other organizational documents) or as provided in
the Indemnification Agreements listed in Section 3.12(q) of the Company
Disclosure Schedule. The Company and the Company Subsidiaries have complied
in all material respects with all laws relating to the employment of labor,
including any provisions thereof relating to wages, hours, collective
bargaining and the payment of social security and similar Taxes, and no
person has, to the knowledge of the Company, asserted that the Company or
any of the Company Subsidiaries is liable in any material amount for any
arrears of wages or any Taxes or penalties for failure to comply with any
of the foregoing, other than any noncompliance that has not had and would
not have a Company Material Adverse Effect. Since the enactment of the
Worker Adjustment and Retraining Notification Act (the "WARN Act"), neither
the Company nor any of the Company Subsidiaries has effectuated, without
complying with the applicable requirements of the WARN Act, (a) a "plant
closing" (as defined in the WARN Act) affecting any site of employment or
one or more facilities or operating units within any site of employment or
facility of the Company or any of the Company Subsidiaries; or (b) a "mass
layoff" (as defined in the WARN Act) affecting any site of employment or
facility of the Company or any of the Company Subsidiaries; nor has the
Company or any of the Company Subsidiaries been affected by any transaction
or engaged in layoffs or employment terminations sufficient in number to
trigger application of any similar state, local or foreign law or
regulation without complying with the applicable requirements of such law
or regulation. From the date of the most recent audited financial
statements included in the Company SEC Documents to the date of this
Agreement, there has not been any adoption or amendment in any material
respect by the Company or any Company Subsidiary of any collective
bargaining agreement or any Company Benefit Plan.

            Section 3.13 Environmental Matters.

            (a) The Company and each Company Subsidiary is and has been in
compliance with all applicable Environmental Laws (as defined below) except
where the failure to be in such compliance, individually or in the
aggregate, would not have a Company Material Adverse Effect. Neither the
Company nor any Company Subsidiary has received any written communication
from any person or Governmental Entity that alleges that the Company or any
Company Subsidiary is not or has not been in compliance with applicable
Environmental Laws, except for communications with respect to such matters
which, if adversely determined against the Company or any Company
Subsidiary, individually or in the aggregate, have not had and would not
have a Company Material Adverse Effect.

            (b) The Company and each Company Subsidiary have obtained all
permits and other governmental authorizations (collectively, the
"Environmental Permits") necessary under applicable Environmental Laws for
the construction of its facilities and the conduct of its operations as
currently conducted, as applicable, and all such Environmental Permits are
in good standing or, where applicable, a renewal application has been
timely filed and is pending agency approval, and the Company and each
Company Subsidiary are in compliance with all terms and conditions of the
Environmental Permits except where the failure to be in such compliance,
individually or in the aggregate, would not have a Company Material Adverse
Effect.

            (c) There is no Environmental Claim (as defined below) pending,
or, to the knowledge of the Company, threatened:

                  (i)  against the Company or any Company Subsidiary;

                  (ii) to the knowledge of the Company, against any person
      or entity whose liability for any such Environmental Claim the
      Company or any Company Subsidiary has retained or assumed either
      contractually or by operation of law; or

                  (iii) against any real or personal property or operations
      which the Company or any Company Subsidiary owns, leases or manages,
      in whole or in part;

            in each case, except for such Environmental Claims that,
individually or in the aggregate, would not have a Company Material Adverse
Effect.

            (d) To the knowledge of the Company, there have not been any
Releases (as defined below) of any Hazardous Material (as defined below)
that would be reasonably likely to form the basis of any Environmental
Claim against the Company or any Company Subsidiary, or against any person
whose liability for any Environmental Claim the Company or any Company
Subsidiary has retained or assumed by contract or by operation of law in
each case, except for such Releases that, individually or in the aggregate,
would not have a Company Material Adverse Effect.

            (e) Neither the Company nor any of the Company Subsidiaries has
entered into any agreements with any non-governmental persons requiring the
Company or any Company Subsidiary to indemnify, reimburse or provide
contribution to such other person for any matter related to Environmental
Laws, Hazardous Materials, or the environment, except for such matters that
(i) have been fully resolved and where the Company or any Company
Subsidiary has no further monetary or non-monetary obligation or (ii) the
enforcement of which, individually or in the aggregate, would not have a
Company Material Adverse Effect.

            (f) To the knowledge of the Company, compliance with all
applicable Environmental Laws (including proposed regulations) will not
require the Company or any Company Subsidiary to incur material
expenditures beyond that currently budgeted in the five Company fiscal
years beginning with January 1, 2000 (as disclosed in Section 3.13(f) or
Section 5.1 of the Company Disclosure Schedule), including the costs of
pollution control equipment required or reasonably contemplated to be
required in the future.

            (g) From January 1, 1997, to the date of this Agreement, the
Company and the Company Subsidiaries have not received any written requests
for information pursuant to Section 114(a) of the federal Clean Air Act or
any state analogue to the federal Clean Air Act, from any Governmental
Entity with respect to the Company's or any Company Subsidiary's compliance
with the new source review requirements under the federal Clean Air Act,
any state analogue to the federal Clean Air Act, or any regulations
promulgated thereunder.

            (h)   In this Agreement:

      "Environmental Claims" means any and all administrative, regulatory
or judicial actions, suits, demand letters, directives, claims, liens,
investigations or written notices by any person or entity (including any
Governmental Entity) alleging potential liability (including potential
responsibility for or liability for enforcement, investigatory costs,
cleanup costs, spent fuel or waste disposal costs, decommissioning costs,
governmental response costs, removal costs, remediation costs, natural
resources damages, property damages, personal injuries or civil or criminal
penalties) arising out of, based on or resulting from (A) the presence,
Release or threatened Release into the environment of any Hazardous
Materials at any location or (B) circumstances forming the basis of any
violation or alleged violation of any Environmental Law or (C) any and all
claims by any third party seeking damages, contribution, indemnification,
cost recovery, compensation or injunctive relief resulting from the
presence or Release of any Hazardous Materials.

      "Environmental Laws" means all federal, state and local laws,
principles of common laws, rules, regulations, ordinances, orders and
directives, relating to pollution or protection of the environment
(including indoor or ambient air, surface water, groundwater, land surface
or subsurface strata) or protection of human health as it relates to the
environment, including laws and regulations relating to Releases or
threatened Releases of Hazardous Materials, or otherwise relating to the
manufacture, processing, generation, use, treatment, storage, disposal,
transport or handling of Hazardous Materials.

      "Hazardous Materials" means any petroleum or petroleum products,
radioactive materials, asbestos, polychlorinated biphenyls, and any other
chemical, material, substance or waste, regulated under any applicable
Environmental Law.

      "Release" means any release, spill, emission, leaking, injection,
deposit, disposal, discharge, dispersal or leaching or migration into or
through the environment.

            Section 3.14 Title to Real Property. Section 3.14 of the
Company Disclosure Schedule lists all real property owned or leased by the
Company or the Company Subsidiaries as of the date of this Agreement, with
a book value in excess of $2,000,000. Except as has not had and would not
have a Company Material Adverse Effect, the Company and each Company
Subsidiary: (i) owns and has good, valid and marketable title in fee simple
to the real property owned by such party, free and clear of Liens, except
for (A) minor imperfections of title, easements and rights of way, none of
which, individually or in the aggregate, materially detracts from the value
of or materially impairs the use of the affected property or materially
impairs the operations of the Company or any Company Subsidiary, (B) Liens
for current Taxes not yet due and payable and (C) Liens disclosed on the
Company Disclosure Schedule ((A), (B) and (C) are collectively referred to
as "Permitted Company Liens"); (ii) is in peaceful and undisturbed
possession of the space and/or estate under each lease under which it is a
tenant, and there are no material defaults by it as tenant thereunder; and
(iii) has good and valid rights of ingress and egress to and from all the
real property owned or leased by such party from and to the public street
systems for all usual street, road and utility purposes. The failure to
hold any easements or rights of way will not have a Company Material
Adverse Effect.

            Section 3.15 Assets Other than Real Property Interests. Other
than as would not have a Company Material Adverse Effect, the Company or a
Company Subsidiary has good and valid title to all material assets
reflected on the most recent balance sheet included in the Company SEC
Reports (the "Balance Sheet") or thereafter acquired, except those sold or
otherwise disposed of for fair value since the date of the Balance Sheet in
the ordinary course of business consistent with past practice and not in
violation of this Agreement, in each case free and clear of all mortgages,
liens, security interests or encumbrances of any kind except (i)
mechanics', carriers', workmen's, repairmen's or other like liens arising
or incurred in the ordinary course of business, liens arising under
original purchase price conditional sales contracts and equipment leases
with third parties entered into in the ordinary course of business and that
may thereafter be paid without penalty, (ii) mortgages, liens, security
interests and encumbrances which secure debt that is reflected as a
liability on the Balance Sheet and the existence of which is indicated in
the notes thereto, and (iii) other imperfections of title or encumbrances,
if any, which do not, individually or in the aggregate, materially impair
the continued use and operation of the assets to which they relate in the
business of the Company and each of the Company Subsidiaries as presently
conducted or which, individually or in the aggregate, would not have a
Company Material Adverse Effect. Each item of material tangible personal
property of the Company and the Company Subsidiaries is in all material
respects in good working order and is adequate and sufficient for the
Company's current use, ordinary wear and tear excepted and except for any
failures which, individually or in the aggregate, would not have a Company
Material Adverse Effect. All leased personal property of the Company and
its Subsidiaries is in the condition required of such property by the terms
of the lease applicable thereto during the term of the lease and upon the
expiration thereof, except for any failures which, individually or in the
aggregate, would not have a Company Material Adverse Effect.

            Section 3.16 Intellectual Property. The Company and each of the
Company Subsidiaries own, or possess licenses or other valid rights to use,
all patents, patent rights, trademarks, trademark rights, trade names,
trade name rights, copyrights, service marks, service mark rights, trade
secrets, applications to register, and registrations for, the foregoing
trademarks, service marks, know-how and other proprietary rights and
information (collectively, "Intellectual Property") necessary in connection
with the business of the Company and the Company Subsidiaries as currently
conducted, except where the failure to possess such rights or licenses or
valid rights to use would not have a Company Material Adverse Effect. The
conduct of the business of the Company and each of the Company Subsidiaries
as currently conducted does not infringe upon any Intellectual Property of
any third party except where such infringement would not result in a
Company Material Adverse Effect, and no person is infringing upon any
Intellectual Property of the Company or any Company Subsidiary except where
such infringement would not have a Company Material Adverse Effect.

            Section 3.17 Transactions with Affiliates. Other than contracts
with respect to the provision of steam or electricity which have been
approved by the IURC (as defined in Section 6.3), Section 3.17 of the
Company Disclosure Schedule lists, as of the date of this Agreement, all
the agreements, contracts or other arrangements between the Company and any
Company Subsidiary, on the one hand, and any affiliate (other than the
Company or such Company Subsidiary), on the other hand, the amount of which
exceeds $60,000 annually, or in the aggregate. Each such agreement or
arrangement was negotiated on an arms-length basis and is no less favorable
to the Company or such Company Subsidiary than the Company or such Company
Subsidiary could have obtained from an unaffiliated third party.

            Section 3.18 Brokers; Schedule of Fees and Expenses. No broker,
investment banker, financial advisor or other person, other than UBS
Warburg LLC and Goldman, Sachs & Co., the fees and expenses of which will
be paid by the Company, is entitled to any broker's, finder's, financial
advisor's or other similar fee or commission in connection with the
transactions contemplated hereby based upon arrangements made by or on
behalf of the Company. The estimated fees to be paid pursuant to this
Section 3.18 are set forth in Section 3.18 of the Company Disclosure
Schedule.

            Section 3.19    Opinion of Financial Advisor.  The Company has
received the opinion of UBS Warburg LLC, dated the date of this Agreement,
to the effect that, as of such date, the consideration to be received in
the Exchange by the holders of Company Common Stock is fair from a
financial point of view, a signed copy of which opinion has been delivered
to Parent promptly following the execution of this Agreement.

            Section 3.20 Capacity to Serve Peak Demand. Section 3.20 of the
Company Disclosure Schedule sets forth a schedule of the purchase power
contracts or commitments entered by the Company prior to the date of this
Agreement for the summer of the year 2000. The Company believes, as of the
date of this Agreement, that these contracts, commitments and its own
generation capacity are adequate to meet its expected peak demand for such
period.

            Section 3.21 Accounting Matters. As of the date of this
Agreement, the Company, after consultation with its independent public
accountants, believes that no conditions exist that would preclude the
Company from being a party to a transaction accounted for as a
pooling-of-interests for accounting purposes in accordance with GAAP and
applicable SEC regulations, including the transactions contemplated hereby.


                                 ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF PARENT

            Parent represents and warrants to the Company that, except as

or otherwise hold its properties and assets and to conduct its businesses
as presently conducted, other than such franchises, licenses, permits,
authorizations and approvals the lack of which, individually or in the
aggregate, has not had and would not have a Parent Material Adverse Effect.
The term "Parent Material Adverse Effect" means an event, change, cause or
effect which is materially adverse to the business, operations, properties,
assets, liabilities, prospects, condition (financial or otherwise) or
results of operations of Parent or the ability of Parent to consummate the

By-laws (the "Parent By-laws") that are referenced as exhibits to Parent's
Form 10-K for the year ended December 31, 1999, are complete and correct
copies thereof. The Parent Charter and the Parent By-laws are in full
force and effect.

            Section 4.3 Capital Structure. The authorized capital stock of
Parent consists of (a) 1,200,000,000 shares of Parent Common Stock par

party or otherwise bound. There are no issued or outstanding bonds,
debentures, notes or other indebtedness of Parent having the right to vote

Parent has all requisite corporate power and authority to execute and
deliver this Agreement and to consummate the Exchange. The execution and
delivery by Parent of this Agreement and the consummation by it of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Parent. Parent has adopted this Agreement.
Parent has duly executed and delivered this Agreement, and assuming the due
authorization and delivery thereof by the Company, this Agreement
constitutes its legal, valid and binding obligation, enforceable against it
in accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium, or other similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

            Section 4.5 SEC Documents. The filings required to be made by
Parent under the Securities Act and the Exchange Act, as the case may be,
have been filed and complied, as of their respective dates, in all material
respects with all applicable requirements of the Securities Act or the
Exchange Act, as the case may be, and the rules and regulations thereunder.
Parent has made available to the Company a true and complete copy of each
report, schedule, registration statement and definitive proxy statement and
all amendments thereto filed with the SEC by Parent pursuant to the
requirements of the Securities Act or the Exchange Act since January 1,
1998 (as such documents have since the time of their filing been amended,
the "Parent SEC Documents"). As of its respective date, each Parent SEC
Document complied in all material respects with its requirements, and did
not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading. The audited consolidated financial statements of
Parent and the unaudited interim financial statements included in the
Parent SEC Documents comply as to form in all material respects with
applicable accounting requirements and the published rules, and regulations
of the SEC with respect thereto, have been prepared in accordance with GAAP
applied on a consistent basis during the periods involved (except as may be
indicated in the notes thereto) and fairly present the consolidated
financial position of Parent and its consolidated Subsidiaries as of the
dates thereof and the consolidated results of their operations and cash
flows for the periods then ended (subject, in the case of unaudited
statements, to normal year-end audit adjustments).

            Section 4.6  No Conflicts; Consents.

            (a) The execution and delivery by Parent of this Agreement does
not, and the consummation of the Exchange and compliance with the terms
hereof will not, conflict with, or result in any violation of or default
(with or without notice or lapse of time, or both) under, or give rise to a
right of termination, cancellation or acceleration of any obligation or to
loss of a material benefit under, or result in the creation of any Lien
upon any of the properties or assets of Parent or any of its Subsidiaries
under, any provision of (i) the charter or organizational documents of
Parent or any of its Subsidiaries, (ii) subject to obtaining the third
party consents (the "Parent Required Consents") set forth in Section 4.6(a)
of the Parent Disclosure Schedule, any Contract to which Parent or any of
its Subsidiaries is a party or by which any of their respective properties
or assets is bound, or (iii) subject to the filings and other matters
referred to in Section 4.6(b), any Judgment or Law existing on the date
hereof applicable to Parent or any of its Subsidiaries or their respective

above, any such items that, individually or in the aggregate, have not had
and would not have a Parent Material Adverse Effect.

            (b) No Consent of, or registration, declaration or filing with,
any Governmental Entity is required to be obtained or made by or with

of the Exchange, other than (i) compliance with and filings by Parent under
the HSR Act, (ii) the filing with the SEC of such reports under Section 13
of the Exchange Act as may be required in connection with this Agreement
and the Exchange, (iii) the filing of the Articles of Share Exchange with
the Secretary of State of the State of Indiana, (iv) the approval of the
FERC under Section 203 and any directly related section of or regulation
under the Power Act for the sale or disposition of jurisdictional
facilities of the Company, or an order under the Power Act disclaiming
jurisdiction over the Exchange, (v) the approval by the SEC pursuant to
Section 9(a)(2) of PUHCA, (vi) the filing with the FCC of the applications
required under Section 310(d) of the Communications Act of 1934, as
amended, and approval by the FCC thereof, (vii) such filings as may be
required in connection with the taxes described in Section 6.8, (viii)
filings under any applicable state takeover Law, (ix) the filing of the
Joint Registration/Proxy Statement (as defined below) with the SEC on Form
S-4, (x) the listing of Parent Common Stock with the NYSE, (xi) the filing
of a registration statement with the SEC as contemplated by Section 2.4(d),
(xii) compliance with state blue sky laws, and (xiii) such other items (A)
required solely by reason of the participation of the Company (as opposed
to any third party) in the Exchange or (B) that, individually or in the
aggregate, would not prevent the consummation of the transactions hereby
and have not had and would not have a Parent Material Adverse Effect.

            Section 4.7 Compliance with Applicable Laws. Parent is not in
violation of, or to its knowledge, under investigation with respect to any
violation of, or has been given written notice of or been formally charged
with any violation of, any law, statute, order, rule, regulation, ordinance
or judgment, permit, license, concession or franchise of any Governmental
Entity, except for violations which individually or in the aggregate have
not had and would not have a Parent Material Adverse Effect. Parent is not
in breach or violation of or in default in the performance or observance of
any term or provision of, and no event has occurred which, with lapse of
time or action by a third party, could result in a default by Parent under
(i) the Parent Charter or the Parent By-laws or (ii) any contract,
commitment, agreement, indenture, mortgage, loan agreement, note, lease,
bond, license, approval or other instrument to which it is a party or by
which Parent is bound or to which any of its property is subject, except,
in the case of clause (ii) above, for violations, breaches or defaults
which individually or in the aggregate have not had and would not have a
Parent Material Adverse Effect.

            Section 4.8 Absence of Undisclosed Liabilities. Except for
liabilities, obligations or contingencies which would not, in the
aggregate, have a Parent Material Adverse Effect, or which are accrued or
reserved against in the consolidated financial statements of Parent or
reflected in the notes thereto for the year ended December 31, 1999, or the
quarter ended March 31, 2000, or which were incurred after December 31,
1999 in the ordinary course of business, Parent has no liabilities or
obligations (whether absolute, accrued, contingent or otherwise and
including margin loans) which are material to Parent and its Subsidiaries
taken as a whole.

            Section 4.9 Stockholder Approval. As long as Parent is not
required to issue 20% or more of the number of shares of Parent Common
Stock outstanding as of the Effective Time in connection with the Exchange,
the issuance of shares of Parent Common Stock in connection with the
Exchange does not, and the transactions contemplated hereby do not, require
approval by the stockholders of Parent.

            Section 4.10 Litigation. As of the date of this Agreement,
there is no suit, action or proceeding pending or, to the knowledge of
Parent, threatened against Parent, any of its Subsidiaries or any of their
affiliated entities that, individually or in the aggregate, has had or
would have a Parent Material Adverse Effect, nor is there any Judgment
outstanding against Parent, any of its Subsidiaries or any of their
affiliated entities that has had or would have a Parent Material Adverse
Effect.

            Section 4.11 Absence of Certain Changes or Events. From
December 31, 1999 to the date of this Agreement, Parent has conducted its
business only in the ordinary course consistent with past practice, and
during such period (i) there has not been any event, change, effect or
development that, individually or in the aggregate, has had or would have a
Parent Material Adverse Effect, (ii) there has not been any material
election with respect to Taxes by Parent or any settlement or compromise of
any material Tax liability or refund of Parent, and (iii) there has not
been any material change in accounting methods, principles or practices by
Parent, except insofar as may have been required by a change in GAAP or SEC
accounting regulations or guidelines or applicable law.

            Section 4.12 Brokers. No broker, investment banker, financial
advisor or other person, other than Lehman Brothers Inc., is entitled to
any broker's, finder's, financial advisor's or other similar fee or
commission in connection with the Exchange based upon arrangements made by
or on behalf of Parent.

            Section 4.13 Ownership of Company Common Stock. As of the date
of this Agreement, none of Parent or any of Parent's Subsidiaries or other
affiliates, either individually or as part of a group for purposes of Rule
13d-3 under the Exchange Act, beneficially owns such number of shares of
Company Common Stock so as to constitute an "interested shareholder" within
the meaning of Section 23-1-43-10 for purposes of Section 23-1-43-18 under
the BCL or Art. 10 of the Company Charter. Parent is not an "Acquiring
Person" within the meaning of the Company Rights Plan.

            Section 4.14 Regulatory Status. Neither Parent nor any
"subsidiary company" or "affiliate" (as such terms are defined in PUHCA) of
Parent is a "public utility company" within the meaning of PUHCA, other
than, as of the date of this Agreement, Entity C.

            Section 4.15 Tax-Free Reorganization. As of the date of this
Agreement, Parent knows of no fact that is reasonably likely to prevent the
Exchange, if consummated as of the date of this Agreement, from qualifying
as a reorganization within the meaning of Section 368(a) of the Code.

            Section 4.16 Accounting Matters. As of the date of this
Agreement, Parent, after consultation with its independent public
accountants, believes that no conditions exist that would preclude Parent
from being a party to a transaction accounted for as a pooling-of-interests
for accounting purposes in accordance with GAAP and applicable SEC
regulations including the transactions contemplated hereby.

arrangement with any of their respective affiliates (other than
intra-company agreements) other than such agreements and arrangements as
are entered into in the usual, ordinary and regular course of business and

prior to making any filing (or any amendment thereto), or effecting any
agreement, commitment, arrangement or consent, whether written or oral,
formal or informal, with respect thereto; provided, however, that in no
event shall the Company be obligated to discuss or consult with Parent with
respect to any of the foregoing if, in the opinion of the Company's outside
counsel, to do so would be inconsistent with applicable Law. Except as
provided in Section 5.1(d) of the Company Disclosure Schedule, the Company
shall not, and shall cause the Company Subsidiaries not to, make any filing

not permit any Company Subsidiary to (i) enter into, modify, amend,

rights or claims therein) if such contract or contracts are material to the
Company and the Company Subsidiaries taken as a whole or if the term of
such new contract or agreement, or the existing contract following and as a
result of such amendment, modification or renewal, is or would exceed
twenty-four months, or (ii) enter into, modify, amend or renew any contract
or agreement to which the Company or any Company Subsidiary is a party (or
waive, release or assign any material rights or claims therein) if the
dollar amount of such new contract or agreement, or the existing contract
or agreement following and as a result of such amendment, modification or
renewal is or would be in excess of $10,000,000, except, in the case of
clauses (i) and (ii) above, for (A) contracts entered into in the ordinary
course of business consistent with past practice if such contracts relate

foregoing, if such contracts would be permitted under Section 5.1(m), and

            (e) Insurance. The Company shall, and shall cause each Company
Subsidiary to, self-insure in accordance with customary industry practices
or maintain with financially responsible insurance companies insurance in

material respects for companies engaged in the electric and gas utility
industry and employing such methods of generating electric power and fuel
sources similar to the methods employed and fuels used by the Company or
the Company Subsidiaries.

            (f) Permits. The Company shall, and shall cause each Company
Subsidiary to, use reasonable best efforts to maintain in effect all
existing governmental permits which are material to the operations of the
Company or any of the Company Subsidiaries.

Company shall not permit any Company Subsidiary to, pay, discharge, settle,
compromise or satisfy any claims, liabilities or obligations (absolute,
accrued, asserted or unasserted, contingent or otherwise) material to the
Company and the Company Subsidiaries, taken as a whole, other than any such
payment, discharge, settlement, compromise or satisfaction (i) of the
applicable claim, liability or obligation in accordance with its terms or,
(ii) in the ordinary course of business consistent with past practice
(which includes the payment of final and unappealable judgments), of
liabilities reflected or reserved against in, or contemplated by, the most
recent consolidated financial statements or the notes thereto of the
Company SEC Documents filed prior to the date hereof, or incurred in the
ordinary course of business consistent with past practice.

levels such that the aggregate number of employees of Entity I is no
greater than 1900 and the aggregate number of employees of the Company and
the Company Subsidiaries (other than Entity I) is no greater than 100.

            (i) Tax-Exempt Status. The Company shall not, nor shall the
Company permit any Company Subsidiary to, take any action that, to the
knowledge of the Company would likely jeopardize the qualification of any
material amount of the Company's outstanding revenue bonds which qualify as
of the date of this Agreement under Section 142(a) of the Code as "exempt
facility bonds" or as tax-exempt industrial development bonds under Section
103(b)(4) of the Internal Revenue Code of 1954, as amended, prior to the
Tax Reform Act of 1986.

            (j) WARN Act. The Company shall not take any action that would

5.1(l) of the Company Disclosure Schedule, the Company shall not, nor shall
the Company permit any Company Subsidiary to, enter into a new line of
business or make any change in the line of business in which it engages as
of the date of this Agreement, except that the Company may establish a new
wholly owned Subsidiary to take over the operation and maintenance of a
steam plant, as disclosed on Section 5.1(l) of the Company Disclosure
Schedule, but shall not in connection therewith hire any personnel.

            (l) Hedging. Except as set forth in Section 5.1(m) of the

generating, purchasing and selling energy to firm wholesale and retail
customers and other than sales of transmission capacity as required by law.

            (m) Other Actions. The Company and Parent shall not, and shall
not permit any of their respective Subsidiaries to, take any action that
would, or that would reasonably be expected to, result in (i) any of the
representations and warranties of such party set forth in this Agreement
that is qualified as to materiality becoming untrue, (ii) any of such
representations and warranties that is not so qualified becoming untrue in
any material respect, or (iii) except as otherwise permitted by Section

            (a) From and after the date hereof, (i) the Company will not,
and will not authorize or permit any of its Representatives to, directly or
indirectly, solicit, initiate or encourage (including by way of furnishing
information) or take any other action knowingly to facilitate any inquiries
or the making of any proposal which constitutes or may reasonably be
expected to lead to an Acquisition Proposal (as defined in Section 5.2(b))
from any person, or engage in any discussion or negotiations relating

prior to receipt of the Company Shareholders' Approval (the "Company
Applicable Period"), (i) in response to an Acquisition Proposal which was
not solicited by it or its Representatives and which did not otherwise
result from a breach of this Section 5.2, if the Company Board reasonably
believes in good faith, after consultation with its financial advisors,
that an Acquisition Proposal could reasonably lead to a transaction meeting
the requirements of a Superior Proposal (as defined in Section 5.2(b)), and
subject to providing Parent with prior written notice of its decision to
take such action (the "Company Notice") and compliance with Section 5.2(c),
(1) furnish information with respect to the Company and the Company
Subsidiaries to any person making such Acquisition Proposal (pursuant to a
customary confidentiality agreement) and (2) participate in discussions or

modify, or propose publicly to withdraw or modify, its position with
respect to this Agreement or the Exchange or approve or recommend, or
propose publicly to approve or recommend, an Acquisition Proposal), and/or
(iii) in the event that during the Company Applicable Period the Company
Board reasonably believes in good faith, after consultation with its
financial advisors and outside counsel, that it has received an Acquisition
Proposal that constitutes a Superior Proposal, by action of the Company
Board (subject to this sentence and Section 8.1(d)(ii)), the Company may
terminate this Agreement (and, following the exercise of such termination
right, the Company Board may withdraw or modify in any adverse manner its
approval or recommendation of this Agreement or the Exchange, and approve
or recommend any merger, consolidation, business combination,

Company Applicable Period and is after the third business day following
Parent's receipt of written notice advising Parent that the Company Board
is prepared to accept a Superior Proposal, specifying the material terms
and conditions of such Superior Proposal and identifying the person making
such Superior Proposal. The Company shall immediately cease and terminate
any existing solicitation, initiation, encouragement, activity, discussion
or negotiation with any persons conducted heretofore by the Company or its
Representatives with respect to any of the foregoing.

            (b) As used herein, (i) "Acquisition Proposal" shall mean any

indirect acquisition or purchase of a business (a "Material Business") that
constitutes 15% or more of the net revenues, net income or the assets
(including equity securities) of the Company and the Company Subsidiaries,
taken as a whole, or 15% or more of any class of voting securities of the
Company or any Company Subsidiary owning, operating or controlling a
Material Business, any tender offer or exchange offer that if consummated
would result in any person beneficially owning 15% or more of any class of
voting securities of the Company or any such Company Subsidiary, or any
merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving the Company or any such
Company Subsidiary, other than the transactions contemplated by this
Agreement; provided, however, that no transaction permitted pursuant to
Section 5.1(a)(vii) or a transaction contemplated in Section 6.14 shall be
deemed an Acquisition Proposal for any purpose, (ii) a "Superior Proposal"
shall mean any proposal made by a third party to acquire, directly or
indirectly, including pursuant to a tender offer, exchange offer, merger,
consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction, more than 50% of the combined voting
power of the shares of the Company Common Stock then outstanding or all or
substantially all the assets of the Company which the Company Board
determines in its good faith judgment, after consultation with its
financial advisors and outside counsel, to be clearly and materially more
favorable to the Company's shareholders (taking into account any changes to
the financial terms of this Agreement proposed by Parent in response to
such proposal and all financial and commercial considerations, including
relevant regulatory and other aspects of the proposal and the third party
making such proposal and the conditions and the prospects for completion of
such proposal, and any changes to this Agreement proposed by Parent in
response to such proposal) than the Exchange and the other transactions
contemplated by this Agreement, and (iii) "Representative" shall mean any

writing of the receipt of any Acquisition Proposal or Superior Proposal and
of the receipt of any inquiry with respect to or which the Company
reasonably believes could lead to any Acquisition Proposal or Superior
Proposal. The Company shall promptly advise Parent orally and in writing of
the identity of the person making any such Acquisition Proposal or Superior
Proposal or inquiry and of the material terms of any such Acquisition
Proposal or Superior Proposal and of any material changes thereto.

            Section 5.3 Conduct of Business by Parent. Except for matters
set forth in the Parent Disclosure Schedule or otherwise contemplated by
this Agreement, from the date of this Agreement to the Effective Time or
earlier termination of this Agreement, Parent shall conduct its business in
the usual, regular and ordinary course in substantially the same manner as
previously conducted and use all reasonable efforts to preserve intact, its
current business organization, keep available the services of its current
officers and employees and keep its relationships with customers,
suppliers, licensors, licensees, distributors and others having business
dealings with them, including regulators, to the end that its goodwill and
ongoing business shall be unimpaired at the Effective Time. In addition,
and without limiting the generality of the foregoing, except for matters
set forth in Section 5.3 of the Parent Disclosure Schedule, or as otherwise
required by Law (including Environmental Law), or otherwise contemplated by
this Agreement, from the date of this Agreement to the Effective Time,
Parent shall not do any of the following:

                  (i)  declare, set aside or pay any dividends on, or make
      any other distributions in respect of, any of its capital stock; or

      manner that adversely would affect the rights of the holders of
      Parent Common Stock.


                                 ARTICLE VI

                           ADDITIONAL AGREEMENTS

            Section 6.1  Preparation of Joint Registration/Proxy Statement;
Shareholders Meeting.

            (a) As soon as possible after the date of this Agreement, (i) the
Company shall prepare and file with the SEC the Proxy Statement and (ii)
Parent shall prepare and file with the SEC a registration statement on Form
S-4 (together with all amendments thereto, the "Registration Statement") in
which the Proxy Statement shall be included as a prospectus (the
"Prospectus"), in connection with the registration under the Securities Act
of shares of Parent Common Stock to be issued in the Exchange. The parties
shall cooperate and consult with each other in the preparation of the Proxy
Statement and the Prospectus (together, the "Joint Registration/Proxy
Statement"). Parent shall have the lead drafting role with respect to the
preparation of the Joint Registration/Proxy Statement. Each of the Company
and Parent shall use its reasonable best efforts to respond as promptly as
practicable to any comments of the SEC with respect thereto. Each party
shall notify the other promptly of the receipt of any comments from the SEC
or its staff and of any request by the SEC or its staff for amendments or
supplements to the Joint Registration/Proxy Statement or for additional
information and shall supply the other with copies of all correspondence
between such party or any of its representatives, on the one hand, and the
SEC or its staff, on the other hand, with respect to the Joint
Registration/Proxy Statement. If at any time prior to the Effective Time,
there shall occur any event with respect to Parent or the Company that
should be set forth in an amendment or supplement to the Joint
Registration/Proxy Statement, Parent or the Company, as the case may be,
shall promptly notify the other, and Parent and the Company shall cooperate
in preparing and mailing to the Company's shareholders such an amendment or
supplement. The Company shall not mail any Joint Registration/Proxy
Statement, or any amendment or supplement thereto, to which Parent
reasonably objects. The Company shall, as soon as practicable after the
date of this Agreement, (i) distribute to its shareholders the Joint
Registration/Proxy Statement as promptly as practicable after filing with
the SEC in accordance with applicable federal and state law and with the
Company Charter and the Company By-laws; (ii) duly call, give notice of,
convene and hold a meeting of its shareholders (the "Company Shareholders
Meeting") for the purpose of seeking the Company Shareholder Approval;
(iii) subject to compliance with Section 5.2, recommend to its shareholders
the approval of the Exchange, this Agreement and the transactions
contemplated hereby, and (iv) cooperate and consult with Parent with
respect to each of the foregoing matters. Each of the parties shall use its
respective best efforts to take such steps as are necessary to hold the
Company Shareholders Meeting within ninety days of the date of this
Agreement. Without limiting the generality of the foregoing, the Company
agrees that its obligations pursuant to this Section 6.1 shall not be
affected by the commencement, public proposal, public disclosure or
communication to the Company of any Acquisition Proposal.

            (b) Each of the parties hereto shall furnish all information
concerning itself which is required as customary for inclusion in the Joint
Registration/Proxy Statement. The information provided by any party for use
in the Joint Registration/Proxy Statement shall be true and correct in all
material respects without omission of any material fact which is required
to make such information not false or misleading. The Joint
Registration/Proxy Statement will comply as to form in all material
respects with the requirements of the Exchange Act and the rules and
regulations thereunder, except that as of the date the Joint
Registration/Proxy Statement is declared effective, no representation,
covenant or agreement is made by any party with respect to information
supplied by the other party for inclusion in the Joint Registration/Proxy
Statement.

            Section 6.2 Access to Information; Confidentiality. Each party
shall, and shall cause each of its Subsidiaries to, afford to the other
party, and, at the other party's request, to the other party's officers,
directors, employees, accountants, counsel, financial advisors and other
representatives, (i) reasonable access during normal business hours during
the period prior to the Effective Time to all its respective properties
(including access to its facilities, office space and information system),
books, contracts, commitments, personnel and records, budgets, forecasts
and other information (including, but not limited to Tax Returns) and,
during such period, each party shall, and shall cause each of its
Subsidiaries to, except as prohibited by law, furnish promptly to the other
party (a) a copy of each report, schedule, registration statement and other
document filed by it during such period pursuant to the requirements of
federal or state securities laws, or filed with or sent to the SEC, the
FERC, the public utility commission of any state, (ii) reasonable access to
all information concerning the Company, the Company Subsidiaries,
directors, officers and shareholders, properties, facilities or operations
owned, operated or otherwise controlled by the Company, (iii) such
additional information relating to Taxes as either party shall from time to
time reasonably request (or, where applicable, to cooperate with Parent in
collecting such information), including, with respect to the Company,
information relating to (a) Tax basis of the stock of the Company
Subsidiaries, (b) earnings and profits, (c) material Tax elections, (d) net
operating loss carryovers and Tax credit carryovers, (e) intercompany
transactions, (f) reconciliation of book and Tax items, (g) the rollout of
any deferred Tax items, (h) ongoing audits (including copies of any IRS
4564 or other similar information document requests), and (i) the Tax years
for which examinations have been completed, are being conducted, and have
not yet been initiated and (iv) with respect to the Company, reasonable
office space and equipment at the Company's headquarters for the purposes
of designing a transition plan in conjunction with the Company's
Representatives. All information exchanged pursuant to this Section 6.2
shall be subject to the confidentiality agreements dated April 24, 2000,
and July 5, 2000, between the Company and Parent (together the
"Confidentiality Agreement").

            Section 6.3  Reasonable Efforts; Notification; Filings.

            (a) Upon the terms and subject to the conditions set forth in
this Agreement, unless and to the extent permitted by Section 5.2, the
Company Board approves or recommends a Superior Proposal, each of the
parties shall use all commercially reasonable efforts to take, or cause to
be taken, all actions, and to do, or cause to be done, and to assist and
cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Exchange including (i) the obtaining of all necessary
actions or nonactions, waivers, consents and approvals from Governmental
Entities and the making of all necessary registrations and filings,
including filings with Governmental Entities (including complying with the
filing and approval requirements of the FERC, the SEC Exemption Order, the
SEC Approval Order and the certification from the Indiana Utility
Regulatory Commission (the "IURC") addressed to the SEC pursuant to Section
33(a)(2) of PUHCA (the "Indiana Certification") substantially in the form
as attached as Exhibit C hereto or in a form otherwise reasonably
satisfactory to Parent), and the taking of all reasonable steps as may be
necessary to obtain the Company Required Consents, the Parent Required
Consents and an approval or waiver from, or to avoid an action or
proceeding by, any Governmental Entity and that may be necessary to
consummate the transactions contemplated hereby, (ii) the obtaining of all
necessary consents, approvals or waivers from third parties, (iii) the
defending of any lawsuits or other legal proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
Exchange, including seeking to have any stay or temporary restraining order
entered by any court or other Governmental Entity vacated or reversed, and
(iv) the execution and delivery of any additional instruments necessary to
consummate the Exchange and to fully carry out the purposes of this
Agreement.

            (b) Each party hereto shall file or cause to be filed with the
Federal Trade Commission and the Department of Justice any notifications
required to be filed under the HSR Act, and the rules and regulations
promulgated thereunder with respect to the transactions contemplated
hereby.

            (c) Parent and the Company will use commercially reasonable
efforts to coordinate such filings and any responses thereto, to make such
filings promptly and to respond promptly to any requests for additional
information made by either of such agencies. Parent and the Company agree
that they will consult with each other with respect to the obtaining of all
such necessary or advisable permits, consents, approvals and authorizations
of Governmental Entities; provided, however, that it is agreed that (x) the
Company shall have primary responsibility for the preparation and filing of
any applications with or notifications to applicable Indiana regulatory
authorities and (y) Parent shall have primary responsibility for the
preparation and filing of any applications with or notifications to
applicable state regulatory authorities for states other than Indiana and
applicable federal regulatory authorities for approval of the Exchange.
Each of Parent and the Company shall have the right to review and approve
in advance drafts of all such necessary applications, notices, petitions,
filings and other documents made or prepared in connection with the
transactions contemplated by this Agreement, which approval shall not be
unreasonably withheld or delayed. In connection with and without limiting
the foregoing, the Company and the Company Board shall (i) take all action
necessary to ensure that no state takeover statute or similar statute or
regulation is or becomes applicable to the Exchange or this Agreement and
(ii) if any state takeover statute or similar statute or regulation becomes
applicable to this Agreement, take all action necessary to ensure that the
Exchange may be consummated as promptly as practicable on the terms
contemplated by this Agreement and otherwise to minimize the effect of such
statute or regulation on the Exchange. Nothing in this Agreement shall be
deemed to require any party to waive any substantial rights or agree to any
substantial limitation on its operations or to dispose of any significant
asset or collection of assets. Notwithstanding the foregoing, the Company
and its Representatives shall not be prohibited under this Section 6.3 from
taking any action permitted by Section 5.2.

            (d) The Company shall give prompt notice to Parent, and Parent
shall give prompt notice to the Company, of (i) any representation or
warranty made by it contained in this Agreement that is qualified as to
materiality becoming untrue or inaccurate in any respect or any such
representation or warranty that is not so qualified becoming untrue or
inaccurate in any material respect, (ii) the failure by it to comply with
or satisfy in any material respect any covenant, condition or agreement to
be complied with or satisfied by it under this Agreement, and (iii) any
change or event which, individually or in the aggregate, has had or would
have a Company Material Adverse Effect; provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the
parties under this Agreement.

            (e) Parent agrees that, prior to the Closing, Parent shall not,
and shall cause its Subsidiaries not to, acquire significant electric
generation assets of clearly sufficient magnitude in the relevant market,
for purposes of FERC's analysis of the Exchange, so as to directly and
significantly impair the ability of the parties to obtain the Required
Approval (as defined in Section 7.1(d)).

            (f) Parent and the Company shall use their reasonable best
efforts to develop jointly by no later than October 15, 2000, a plan for
the Company to comply with emission limits that may be imposed as a result
of the United States Environmental Protection Agency's NOx SIP Call, which
plan may include capital expenditure outlays in addition to those
contemplated by this Agreement and the Company Disclosure Schedule. The
Company may make any such capital expenditures in accordance with such
plan.

            Section 6.4  Employee Benefit Plans.

            (a) Parent shall cause individuals who were employed by the
Company or any Company Subsidiary immediately before the Effective Time and
who continue employment with the Company or such Company Subsidiary after
the Effective Time ("Covered Employees") to be provided employee benefits
that are substantially equivalent in the aggregate, at Parent's discretion,
to either (i) those provided under the Company Benefit Plans immediately
before the Effective Time, or (ii) those provided by Parent or its
Subsidiaries to their similarly situated employees from time to time;
provided, however, that nothing contained herein shall be construed as
requiring Parent or the Company after the Closing to continue any specific
plan or as preventing Parent or the Company after the Closing from
establishing and, if necessary, seeking shareholder approval to establish,
any other benefit plans in respect of all or any Covered Employee or any
other employee, or amending the Company Benefit Plans. After the Closing,
Parent does not intend to offer compensation plans to officers of the
Company and its Subsidiaries that are comparable to those historically
available to such persons.

            (b) Parent shall credit, or cause to be credited, to the
Covered Employees all service with the Company and/or its Subsidiaries (and
all service credited to such Covered Employees by the Company and/or its
Subsidiaries or under the Company Benefit Plans) for all purposes, under
any and all benefit plans, programs or arrangements in which the Covered
Employees may participate or from which the Covered Employees may receive
benefits from and after the Effective Time, to the same extent as if
rendered to Parent, the Company or any of their Subsidiaries, provided that
no such service credited shall require the Company and/or its Subsidiaries
to provide for duplication of benefits. Parent shall cause to be waived any
waiting period or pre-existing condition limitation under its (or, after
the Closing, the Company's or their Subsidiaries') welfare plans that might
otherwise apply to any Covered Employee (to the extent that such Covered
Employee was not affected by the waiting period or pre-existing condition
limitation under the applicable Company Benefit Plans as of the Effective
Time). Parent agrees to recognize, or cause to be recognized, the dollar
amount of all expenses incurred by the Covered Employees during the
calendar year in which the Effective Time occurs for purposes of satisfying
such calendar year deductibles and co-payments limitations under the
Company Benefit Plans and/or any relevant benefit plans, programs or
arrangements of Parent, the Company or their Subsidiaries.

            (c) From and after the Effective Time, Parent shall and shall
cause the Company to honor, in accordance with its express terms, each then
existing employment, change of control, severance and termination agreement
between the Company or any of its Subsidiaries and an officer, director or
employee of such Company or Subsidiary.

            Section 6.5  Directors' and Officers' Indemnification and
Insurance.

            (a) From and after the Effective Time, Parent and the Company
shall indemnify, defend and hold harmless each person who is now, or has
been at any time prior to the date hereof or who becomes prior to the
Effective Time, a director or officer of the Company or any of its
Subsidiaries (the "Indemnified Parties") against all losses, claims,
damages, costs and expenses (including reasonable attorneys' fees),
liabilities, judgments and, subject to the proviso of this sentence,
settlement amounts that are paid or incurred in connection with any claim,
action, suit, proceeding or investigation (whether civil, criminal,
administrative or investigative and whether asserted or claimed prior to,
at or after the Effective Time) that is (i) based on, or arises out of, the
fact that such Indemnified Party is or was a director or officer of the
Company or any of its Subsidiaries, and (ii) based on, or arising out of,
or pertaining to this Agreement or the transactions contemplated hereby, in
each case to the fullest extent a corporation is permitted under applicable
law to indemnify its own directors or officers, as the case may be
("Indemnified Liabilities"); provided, however, that neither Parent nor the
Company shall be liable for any settlement of any claim effected without
its written consent. Without limiting the foregoing, in the event that any
such claim, action, suit, proceeding or investigation is brought against
any Indemnified Party (whether arising prior to or after the Effective
Time), (w) the Company following the Effective Time will pay expenses of
the final disposition of any such claim, action, suit, proceeding or
investigation to each Indemnified Party to the full extent permitted by
applicable law promptly after statements therefor are received and
otherwise advance to such Indemnified Party upon request reimbursement of
documented expenses reasonably incurred, in either case to the extent not
prohibited by the BCL; provided, however, that the person to whom expenses
are advanced provides any undertaking required by applicable law to repay
such advance if it is ultimately determined that such person is not
entitled to indemnification; (x) the Indemnified Parties shall retain
counsel reasonably satisfactory to the Company; (y) the Company following
the Effective Time shall pay all reasonable fees and expenses of such
counsel for the Indemnified Parties (subject to the final sentence of this
paragraph) promptly as statements therefor are received; and (z) the
Company following the Effective Time shall use all commercially reasonable
efforts to assist in the defense of any such matter. In the event of any
dispute as to whether an Indemnified Party's conduct complies with the
standards set forth under the BCL and the Company Charter or Company
By-laws, a determination shall be made by independent counsel mutually
acceptable to the Company following the Effective Time and the Indemnified
Party (the "Independent Counsel"); provided, however, that the Company
following the Effective Time shall not be liable for any settlement
effected without its written consent (which consent shall not be
unreasonably withheld). The Indemnified Parties as a group seeking
indemnification with respect to the same or a substantially related matter
may retain only one law firm with respect to such matter except to the
extent that under applicable standards of professional conduct, such
counsel would have conflict representing such Indemnified Party and any
other Indemnified Party or Indemnified Parties.

            (b) Except to the extent required by Law, the Company following
the Effective Time shall not take any action so as to amend, modify, limit
or repeal the provisions for indemnification of Indemnified Parties
contained in the certificates or articles of incorporation or by-laws (or
other comparable charter documents) of the Company following the Effective
Time and its Subsidiaries (which as of the Effective Time shall be no more
favorable to such individuals than those maintained by the Company and its
Subsidiaries on the date hereof) in such a manner as would adversely affect
the rights of any Indemnified Party to be indemnified by such corporations
in respect of their serving in such capacities prior to the Effective Time.
The Company following the Effective Time shall honor all of its
indemnification obligations existing as of the Effective Time.

            (c) For a period of six years after the Effective Time, the
Company shall cause to be maintained in effect policies of directors' and
officers' liability insurance maintained by the Company as of the date of
this Agreement; provided, however, that the Company may substitute therefor
policies of at least the same coverage containing terms that are no less
advantageous with respect to matters occurring prior to or at the Effective
Time to the extent such liability insurance can be maintained annually at a
cost to the Company not greater than 300% for annual premiums for such
directors' and officers' liability insurance, which existing premium costs
are set forth in Section 6.5(c) of the Company Disclosure Schedule;
provided, further, that if such insurance cannot be so maintained or
obtained at such cost, the Company shall maintain or obtain as much of such
insurance as can be so maintained or obtained at a cost equal to 300% of
the current annual premiums of Company for its directors' and officers'
liability insurance.

            (d) The provisions of this Section are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party and each
party entitled to insurance coverage under Section 6.5(c), respectively,
and his or her heirs and legal representatives, and shall be in addition
to, and shall not impair, any other rights an Indemnified Party may have
under the Company Charter or the comparable organization documents of the
Company or any of its Subsidiaries, under the BCL or otherwise.

            Section 6.6 Expenses. Except as provided in Article VIII, all
fees and expenses incurred in connection with the Exchange shall be paid by
the party incurring such fees or expenses, whether or not the Exchange is
consummated.

            Section 6.7 Public Announcements. Parent and the Company shall
consult with each other before issuing, and provide each other the
opportunity to review and comment upon, any press release or other public
statements with respect to the Exchange and shall not issue any such press
release or make any such public statement prior to such consultation,
except as may be required by applicable Law, court process or by
obligations pursuant to any listing agreement with any national securities
exchange.

            Section 6.8 Transfer Taxes. Subject to Section 2.3(b), all
stock transfer, real estate transfer, documentary, stamp, recording and
other similar Taxes (including interest, penalties and additions to any
such Taxes) ("Transfer Taxes") incurred in connection with the Exchange
shall be paid by the Company, and the Company shall cooperate with Parent
in preparing, executing and filing any Tax Returns with respect to such
Transfer Taxes. In no case will Parent pay directly or indirectly any
Transfer Tax incurred in connection with the Exchange.

            Section 6.9 Restructuring. Parent shall file an application
with the SEC which commits Parent, if required by a regulatory order of the
SEC, to enter into an agreement with a third party within three years of
the Effective Time to divest its ownership interest in the PUHCA
jurisdictional business of Entity C or comply with such other conditions as
may be imposed by the SEC; provided, however, that Parent shall not be
required to comply with any such condition that Parent reasonably believes
would have a Company Material Adverse Effect or an adverse effect on Parent
which is material in the context of the transactions contemplated hereby.

            Section 6.10 Rights Agreement; Consequences if Rights
Triggered. The Company Board shall take all action requested in writing by
Parent in order to render the Company Rights inapplicable to the Exchange.
Except as approved in writing by Parent, the Company Board shall not (i)
amend the Company Rights Agreement, (ii) redeem the Company Rights or (iii)
take any action with respect to, or make any determination under, the
Company Rights Agreement, except for any of the foregoing actions which the
Company Board, after consultation with outside counsel, determines in good
faith is required for the Company Board to comply with its fiduciary duties
imposed by law. If any Distribution Date, Share Acquisition Date or
Triggering Event occurs under the Company Rights Agreement at any time
during the period from the date of this Agreement to the Effective Time,
the Company and Parent shall make such adjustment to the Exchange
Consideration as the Company and Parent shall mutually agree so as to
preserve the economic benefits that the Company and Parent each reasonably
expected on the date of this Agreement to receive as a result of the
consummation of the Exchange.

            Section 6.11 Conduct of Business of Parent. Except as may be
required by applicable law or as contemplated by Section 6.9, Parent and
any Subsidiary of Parent shall not engage in any activities (including
allowing or causing a change in the equity or other ownership of Parent)
which would cause a change in Parent's or any equity owner's or affiliate's
status under PUHCA or that would impair the ability of the Company, Parent,
any Subsidiary of Parent or any equity owner or affiliate of Parent to
claim any exemption under PUHCA or subject Parent, any Subsidiary of Parent
or any equity owner or affiliate of Parent to regulation under PUHCA (other
than Section 9(a)(2) or as an exempt holding company under PUHCA) following
the Exchange or acquire such voting securities in a "public utility
company" as defined under Section 2(a)(5) of PUHCA so as to become an
affiliate of such public utility company within the meaning of Section
2(a)(11) of PUHCA.

            Section 6.12  Certain Employee Matters; Headquarters.

            (a) After the Closing, Parent will make available to employees
of the Company employment opportunities within the domestic and
international Parent group substantially equivalent to opportunities as are
made available to other employees of Parent and its Subsidiaries.

            (b) After the Closing, the Company shall, and shall cause
Entity I to, maintain for a period of at least three years following the

law, ordinance, rule, regulation, temporary restraining order, preliminary
or permanent injunctions or other order enacted, entered, promulgated,

obtained. Parent shall reasonably believe that such Required Approval would
not have a Company Material Adverse Effect or an adverse effect on Parent
which is material in the context of the transactions contemplated hereby;
provided, however, that neither of the following shall be deemed to have a
Company Material Adverse Effect or an adverse effect on Parent which is
material in the context of the transactions contemplated hereby: (i) any
condition that affects the rates, terms or conditions of existing or future
power sales transactions between Entity I or Parent or any Subsidiary of
Parent (including Entity C), or which imposes a code of conduct on Entity I

to the consummation of such transactions prescribed by applicable law,
regulation or order have been satisfied.

authorizations shall have been obtained from all Governmental Entities
except for the approvals and authorizations contemplated by Sections
7.1(d), 7.2(e) and 7.2(i), except where the failure to obtain any such
consents, approvals and authorizations would not cause a Company Material
Adverse Effect or an adverse effect on Parent which is material in the
context of the transactions contemplated hereby.

            (f) Registration Statement. The Registration Statement shall
have become effective in accordance with the provisions of the Securities

true and correct in all material respects, as of the date of this Agreement
and as of the Closing Date as though made on the Closing Date, except to
the extent such representations and warranties expressly relate to an
earlier date (in which case such representations and warranties qualified
as to materiality shall be true and correct, and those not so qualified
shall be true and correct in all material respects, on and as of such
earlier date). Parent shall have received a certificate signed on behalf of
the Company by the chief executive officer and the chief financial officer
of the Company to such effect.

            (b) Performance of Obligations of the Company. The Company
shall have performed in all material respects all obligations required to
be performed by it under this Agreement at or prior to the Closing Date.

            (c) Absence of a Company Material Adverse Effect. Except as

date of this Agreement there shall not have been any event, change, effect
or development that, individually or in the aggregate, has had or would
reasonably be expected to have a Company Material Adverse Effect.

            (d) Company Required Consents.  The Company Required Consents
shall have been obtained.

9(a)(2) of PUHCA (the "SEC Approval Order"), and each such order shall be
in full force and effect on the Closing Date. Parent shall be reasonably
satisfied that neither the SEC Exemption Order nor the SEC Approval Order
shall have a Company Material Adverse Effect or an adverse effect on Parent
which is material in the context of the transactions contemplated hereby.

            (f) Closing Certificates. Parent shall have received a
certificate signed by an executive officer of the Company, dated the

could occur pursuant to this Agreement or otherwise that would result in
the triggering of any right or entitlement of the Company shareholders
under the Company Rights Agreement, including a "flip-in" or "flip-over" or
similar event commonly described in such rights plans which, in the
reasonable judgment of Parent, would have or be reasonably likely to result
in a Company Material Adverse Effect or materially change the number of
outstanding equity securities of the Company, and the Company Rights shall
not have become nonredeemable by the Company Board.

            (i) Indiana Utility Regulatory Commission. (i) The IURC shall
have issued the Indiana Certification, (ii) any order of, approval by or
result of any filing, hearing, proceeding, investigation or notice with, or

hearing, proceeding or investigation shall have been conducted or shall be
currently pending before the IURC, or any other Indiana state authority,
which was initiated by a party other than the IURC, or any other Indiana
state authority, and the outcome of which is reasonably likely to result in
a Regulatory Adverse Effect. For purposes of this Agreement, a "Regulatory
Adverse Effect" shall mean an effect that is reasonably likely to have a
Company Material Adverse Effect or an adverse effect on Parent which is
material in the context of the transactions contemplated hereby.

            (j) Tax Opinion. Parent shall have received an opinion of
Skadden, Arps, Slate, Meagher & Flom LLP, special tax counsel to Parent,
dated as of the Closing Date, and in form and substance reasonably

Closing Date from each of Parent and the Company, in each case, in

counsel, which letters shall not have been modified or withdrawn. The

            (b) by either Parent or the Company:

                  (i) if the Exchange is not consummated by the fifteen-

8.1, this Agreement shall forthwith become void and have no effect, without
any liability or obligation on the part of Parent or the Company, other

Section 8.2, Section 8.3 and Article IX which provisions shall survive such

Board of Directors of the parties at any time before or after receipt of

the Company Shareholder Approval, there shall be made no amendment that by
Law requires further approval by the shareholders of the Company or Parent,
without further approval of such shareholders. This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the

inaccuracies in the representations and warranties contained in this
Agreement or in any document delivered pursuant to this Agreement or (c)

part of a party to any such extension or waiver shall be valid only if set
forth in an instrument in writing signed on behalf of such party. The
failure of any party to this Agreement to assert any of its rights under
this Agreement or otherwise shall not constitute a waiver of such rights.

            Section 8.6 Procedure for Termination, Amendment, Extension or
Waiver. A termination of this Agreement pursuant to Section 8.1, an
amendment of this Agreement pursuant to Section 8.4 or an extension or

the case of Parent or the Company, action by its Board of Directors or the
duly authorized designee of its Board of Directors.

held for passive investment purposes which are less than 5% of any class of
the outstanding voting securities or equity of any such entity, and the
term "Company Joint Venture" shall mean a Joint Venture of the Company.

            Section 9.4 Interpretation. When a reference is made in this
Agreement to a Section, such reference shall be to a Section of this
Agreement unless otherwise indicated. The table of contents and headings

            Section 9.5 Severability. If any term or other provision of
this Agreement is invalid, illegal or incapable of being enforced by any
rule or Law, or public policy, all other conditions and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the
economic or legal substance of the transactions contemplated hereby is not
affected in any manner materially adverse to any party. Upon such
determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good
faith to modify this Agreement so as to effect the original intent of the

            Section 9.7 Entire Agreement; No Third-Party Beneficiaries.
This Agreement, taken together with the Company Disclosure Schedule and the
Parent Disclosure Schedule, constitutes the entire agreement and supersedes
all prior agreements and understandings, both written and oral, among the
parties with respect to the Exchange, other than the Confidentiality
Agreement, and, except for the provisions of Article II, Section 6.4(c) and
Section 6.5, is not intended to, and shall not, confer upon any person
other than the parties any rights, claims or remedies.

            Section 9.8 Governing Law. This Agreement shall be governed by,
and construed in accordance with, the laws of the State of New York,

provisions of this Agreement (including the documents or instruments
referred to herein) are expressly governed by or derive their authority
from the BCL.

            Section 9.9 Assignment. Neither this Agreement nor any of the
rights, interests or obligations under this Agreement shall be assigned, in
whole or in part, by operation of law or otherwise by any of the parties
without the prior written consent of the other parties, except that Parent
may assign, in its sole discretion, any of or all its rights, interests and
obligations under this Agreement to any direct or indirect wholly owned
Subsidiary of Parent, but no such assignment shall relieve Parent of any of
its obligations under this Agreement. Any purported assignment without such
consent shall be void. Subject to the preceding sentences, this Agreement
will be binding upon, inure to the benefit of, and be enforceable by, the
parties and their respective successors and assigns.

            Section 9.10 Enforcement. Each of the parties agrees that
irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms
or were otherwise breached. It is accordingly agreed that the parties shall
be entitled to an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions of this
Agreement in any New York state court or any federal court in the state of
New York, this being in addition to any other remedy to which they are
entitled at law or at equity. In addition, each of the parties hereto (a)
consents to submit itself to the personal jurisdiction of any federal court
located in the State of New York or any New York State court in the County
of New York in the event any dispute arises out of this Agreement or the
Exchange, (b) agrees that it will not attempt to deny or defeat such
personal jurisdiction by motion or other request for leave from any such
court, (c) agrees that it will not bring any action relating to this
Agreement or the Exchange in any court other than any New York state court
or any federal court sitting in the State of New York or any New York State
court sitting in the County of New York, and (d) waives any right to trial
by jury with respect to any action related to or arising out of this
Agreement or the Exchange.

            Section 9.11 Further Assurances. Each party will execute such
further documents and instruments and take such further actions as may
reasonably be requested by any other party in order to consummate the
Exchange in accordance with the terms hereof.

            IN WITNESS WHEREOF, Parent and the Company have duly executed
this Agreement, all as of the date first written above.

Ladies and Gentlemen:

                  In connection with the opinions to be delivered pursuant
to Sections 7.2(j) and 7.3(d) of the Agreement and Plan of Share Exchange
(the "Exchange Agreement"), dated as of July 15, 2000, among The AES
Corporation, a Delaware corporation ("Parent"), and IPALCO Enterprises,
Inc., an Indiana corporation (the "Company"), whereby all the issued and
outstanding shares of common stock of the Company will be acquired by
Parent in exchange for shares of common stock of the Parent (the
"Exchange"), and in connection with the filing with the Securities and
Exchange Commission (the "SEC") of the registration statement on Form S-4
(the "Registration Statement"), which includes the Joint Proxy Statement of
Parent and the Company, each as amended or supplemented through the date
hereof, the undersigned certifies and represents on behalf of the Parent,
after due inquiry and investigation, as follows (any capitalized term used
but not defined herein having the meaning given to such term in the
Exchange Agreement):

                  1. The facts, representations and covenants relating to
the Exchange and related transactions as described in the Exchange
Agreement, Registration Statement and the other documents described in the
Registration Statement (including all exhibits and attachments thereto)
are, insofar as such facts pertain to the Parent, true, correct and
complete in all material respects. The Exchange will be consummated in
accordance with the Exchange Agreement.

                  2. The formula set forth in the Exchange Agreement
pursuant to which each issued and outstanding share of Company Common Stock
will be converted into fully paid and nonassessable shares of Parent Common
Stock is the result of arm's length bargaining.

                  3. The fair market value of the Parent Common Stock
received by the shareholders of the Company will be, at the Effective Time,
approximately equal to the fair market value of the Company Common Stock
surrendered in the Exchange.

                  4. In the Exchange, all of the Company Common Stock will
be exchanged solely for Parent Common Stock (except for cash paid in lieu
of fractional shares of Parent Common Stock). The Company has no class of
stock outstanding other than the Company Common Stock. No shares or other
securities of the Company will be issued to the shareholders of the Company
pursuant to the Exchange. For purposes of this representation, any share of
the Company Common Stock redeemed or exchanged in the Exchange for cash or
other property originating, directly or indirectly, with the Parent or any
of its subsidiaries will not be considered as exchanged solely for Parent
Common Stock. Further, no liabilities of the Company or any shareholder of
the Company will be assumed by the Parent in the Exchange, nor will any of
the Company Common Stock acquired by Parent in the Exchange be subject to
any liabilities.

                  5. Following the Exchange, Parent has no plan or
intention to sell, transfer or dispose of any stock of the Company or to
cause the Company to issue additional shares of its stock that would in
either case result in Parent failing to own after the Exchange, directly or
indirectly, at least 80 percent of the total combined voting power of all
classes of Company stock entitled to vote and at least 80 percent of the
total number of shares of all other classes of Company stock.

                  6. If cash payments are made to holders of Company Common
Stock in lieu of fractional shares of Parent Common Stock that would
otherwise be issued to such holders in the Exchange, such payments will be
made for the purpose of saving Parent the expense and inconvenience of
issuing and transferring fractional shares of Parent Common Stock, and will
not represent separately bargained for consideration. The total cash
consideration that will be paid in the Exchange to holders of Company
Common Stock in lieu of fractional shares of Parent Common Stock will not
exceed one percent of the total consideration that will be issued in the
Exchange to shareholders of Company in exchange for their shares of Company
Stock.

                  7. (i) To the knowledge of Parent, neither the Company
nor any corporation related to the Company (as defined in Treasury
Regulation Section 1.368- 1(e)) has purchased, exchanged, redeemed, or
otherwise acquired or has any plan or intention to purchase, exchange,
redeem, or otherwise acquire any Company stock in contemplation of the
Exchange, or otherwise as part of a plan of which the Exchange is a part.

                     (ii) Neither Parent nor any corporation related to
Parent (as defined in Treasury Regulation Section 1.368-1(e)) has any plan
or intent to purchase, exchange, redeem, or otherwise acquire any of the
Parent stock issued in the Exchange, either directly or through any
transaction, agreement or arrangement with any other person (excluding any
fractional shares of the Parent Common Stock exchanged for cash in the
Exchange). To the knowledge of Parent, neither the Company nor any
corporation related to the Company (as defined in Treasury Regulation
Section 1.368- 1(e)) has any plan or intention to purchase, exchange,
redeem, or otherwise acquire any of the Parent stock issued in the
Exchange, either directly or through any transaction, agreement or
arrangement with any other person. For purposes of this representation
letter, a person is considered to own or acquire stock owned or acquired
(as the case may be) by a partnership in which such person is a partner in
proportion to such person's interest in the partnership.

                  8. The Company has not made, and does not have any plan
or intention to make, any distributions prior to, in contemplation of or
otherwise in connection with, the Exchange (other than dividends made in
the ordinary course of business).

                  9. Parent has no plan or intention to, following the
Exchange, liquidate the Company, merge the Company with or into another
corporation in which the Company is not the survivor, sell or otherwise
dispose of shares of the Company, cause the Company to distribute to Parent
or any of its subsidiaries any assets of the Company or the proceeds of any
borrowings incurred by the Company, or cause the Company to sell or
otherwise dispose of any of its assets, except for dispositions made in the
ordinary course of business transfers of assets permitted under Section
368(a)(2)(C) of the Code or Treasury Regulation Section 1.368-1(d) or
1.368-2(k), and the sale of Cleveland District Cooling Corporation,
Cleveland Thermal Energy Corporation, Mid America Energy Resources and
Indianapolis Campus Energy, or the assets of each, for an amount of cash or
other consideration with a fair market value equal to that of the assets
sold in exchange therefor.

                  10. Parent will pay its expenses, if any, incurred in
connection with the Exchange. Parent has not paid (directly or indirectly)
or agreed to assume any expense or other liability, whether fixed or
contingent, of the Company or any of its subsidiaries or any holder of
Company Stock.

                  11. The Company shall pay all transfer taxes attributable
to the Exchange out of the Company's own funds (and not out of funds
provided, directly or indirectly, by Parent).

                  12. Except as specifically set forth in Section 3.2 of
the Exchange Agreement, immediately prior to the time of the Exchange, the
Company will not have outstanding any warrants, options, convertible
securities or any other type of right pursuant to which any person could
acquire Company stock. Simultaneously with the Exchange, all outstanding
warrants, options, convertible securities, and related stock appreciation
rights, if any, to purchase or acquire a share of Company stock granted
under employee incentive or benefits plans, programs or arrangements and
non- employee director plans presently maintained by the Company, together
with all other outstanding awards granted under such plans, will be
canceled or converted into similar instruments of Parent. Immediately
following the Exchange, the only class of Company stock outstanding will be
the Company Common Stock held by Parent.

                  13. Following the Exchange, Parent intends to cause the
Company to continue its "historic business" or to use a significant portion
of its "historic business assets" in a business (as such terms are defined
in Treasury Regulation Section 1.368- 1(d)). To the knowledge of Parent,
the Company has not sold, transferred, or otherwise disposed of any of its
assets so as to prevent the Parent or members of its "qualified group" from
continuing the "historic business" of the Company or using a significant
portion of the Company's "historic business assets" in a business after the
Exchange (within the meaning of such terms in Treasury Regulation section
1.368-1(d)).

                  14. Parent is not an investment company as defined in
Section 368(a)(2)(F)(iii) and (iv) of the Code.

                  15. The Parent will not take, and will not cause Company
to take, any position on any Federal, state or local income or franchise
tax return, or take any other tax reporting position, that is inconsistent
with the treatment of the Exchange as a reorganization within the meaning
of Section 368(a) of the Code, unless otherwise required by a
"determination" (as defined in Section 1313(a)(1) of the Code) or by
applicable state or local tax law (and then only to the extent required by
such applicable state or local tax law).

                  16. None of the compensation received (or to be received)
by any stockholder-employee or stockholder-independent contractor of the
Company is (or will be) separate consideration for, or is (or will be)
allocable to, any of such person's Company Common Stock surrendered in the
Exchange. None of the Parent Stock that will be received by any
stockholder-employee or stockholder-independent contractor of the Company
in the Exchange represents separately bargained-for consideration which is
allocable to any employment agreement or arrangement. The compensation paid
to any stockholder-employee or stockholder-independent contractor pursuant
to any agreement entered into in connection with the Exchange will be for
services actually rendered, will be commensurate with amounts paid to third
parties bargaining at arm's length for similar services or covenants, and
will be determined independent of the determination of the consideration to
be paid for the Company Common Stock.

                  17. There is no intercorporate indebtedness existing
between Parent (or any of its subsidiaries) and the Company (or any of its
subsidiaries) that was issued, acquired or will be settled at a discount.

                  18. Parent is not under the jurisdiction of a court in a
Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the
Code.

                  19. Neither Parent nor any person related to the Parent
(within the meaning of Treasury Regulation section 1.368-1(e)(3)) owns,
directly or indirectly, nor have they owned during the past five years,
directly or indirectly, any shares of the stock of the Company.

                  20. Parent shall satisfy the information reporting
requirements of Treasury Regulation section 1.368-3 with respect to the
Exchange.

                  21. Parent Common Stock entitles the holder to vote for
the board of directors of Parent.

                  22. The Exchange Agreement, the Registration Statement
and the other documents described in the Registration Statement (including
all exhibits and attachments thereto) represents the entire understanding
between the Parent and the Company regarding the Exchange, and there are no
other written or oral agreements between the Parent and the Company
regarding the Exchange.

                  23. The Exchange is being undertaken for purposes of
enhancing the business of the Company and for other good and valid business
purposes of the Company.

                  24. On the date of the Exchange, the fair market value of
the assets of the Company will exceed the sum of its liabilities, plus the
amount of liabilities, if any, to which such assets are subject.

                  25. No holders of Company stock have appraisal or
dissenters' rights with respect to the Exchange under any applicable law.

                  26. The undersigned is authorized to make all the
representations set forth herein on behalf of Parent.

                  The undersigned acknowledges that (i) the opinions to be
delivered pursuant to Sections 7.2(j) and 7.3(d) of the Exchange Agreement
will be based on the accuracy and completeness of the representations set
forth herein and on the accuracy and completeness of the representations
and warranties and the satisfaction of the covenants and obligations
contained in the Exchange Agreement and the various other documents related
thereto, and (ii) such opinions will be subject to certain limitations and
qualifications including that it may not be relied upon if any such
representations or warranties are not accurate and complete or if any of
such covenants or obligations are not satisfied in all material respects.
Parent understands that Skadden, Arps, Slate, Meagher & Flom LLP and
Cravath, Swaine & Moore have not undertaken to independently verify the
facts providing the basis of this letter nor have they been asked to do so.

                  The undersigned acknowledges that such opinions will not
address any tax consequences of the Exchange or any action taken in
connection therewith except as expressly set forth in such opinions.


                                                 Very truly yours,

                                                 The AES Corporation

Ladies and Gentlemen:

            In connection with the opinions to be delivered pursuant to
Sections 7.2(j) and 7.3(d) of the Agreement and Plan of Share Exchange (the
"Exchange Agreement"), dated as of July 15, 2000, among The AES
Corporation, a Delaware corporation ("Parent"), and IPALCO Enterprises,
Inc., an Indiana corporation (the "Company"), whereby all the issued and
outstanding shares of common stock of the Company will be acquired by

Parent and the Company, each as amended or supplemented through the date
hereof, the undersigned certifies and represents on behalf of the Company,
after due inquiry and investigation, as follows (any capitalized term used
but not defined herein having the meaning given to such term in the
Exchange Agreement):

            1. The facts, representations, and covenants relating to the
Exchange and related transactions as described in the Exchange Agreement,
Registration Statement and the other documents described in the
Registration Statement (including all exhibits and attachments thereto)
are, insofar as such facts pertain to the Company, true, correct and
complete in all material respects. The Exchange will be consummated in
accordance with the Exchange Agreement.

            2.    The formula set forth in the Exchange Agreement pursuant to
which each issued and outstanding share of Company Common Stock will be

is the result of arm's length bargaining.

            3. The fair market value of the Parent Common Stock received by

            4. In the Exchange, all of the Company Common Stock will be

Common Stock. Further, no liabilities of the Company or any shareholder of
the Company will be assumed by the Parent in the Exchange, nor will any of
the Company Common Stock acquired by Parent in the Exchange be subject to
any liabilities.

            5. Following the Exchange, the Company has no plan or intention
to issue additional shares of its stock that would result in Parent failing
to own after the Exchange, directly or indirectly, at least 80 percent of
the total combined voting power of all classes of Company stock entitled to
vote and at least 80 percent of the total number of shares of all other
classes of Company stock. To the best knowledge of the Company, Parent has
no plan or intention to sell, transfer or dispose of any stock of the
Company or to cause the Company to issue additional shares of its stock
that would in either case result in Parent failing to own after the
Exchange, directly or indirectly, at least 80 percent of the total combined
voting power of all classes of Company stock entitled to vote and at least
80 percent of the total number of shares of all other classes of Company
stock.

            6. If cash payments are made to holders of Company Common Stock
in lieu of fractional shares of Parent Common Stock that would otherwise be
issued to such holders in the Exchange, such payments will be made for the
purpose of saving Parent the expense and inconvenience of issuing and

consideration that will be paid in the Exchange to holders of Company
Common Stock in lieu of fractional shares of Parent Common Stock will not
exceed one percent of the total consideration that will be issued in the
Exchange to shareholders of Company in exchange for their shares of Company
Stock.

            7. (i) Neither the Company nor any corporation related to the
Company (as defined in Treasury Regulation Section 1.368-1(e)) has
purchased, exchanged, redeemed, or otherwise acquired or has any plan or
intention to purchase, exchange, redeem, or otherwise acquire any Company
stock in contemplation of the Exchange, or otherwise as part of a plan of
which the Exchange is a part.

                  (ii) The Company is not aware of any plan or intention on
the part of Parent or any corporation related to Parent (as defined in
Treasury Regulation Section 1.368-1(e)) to purchase, exchange, redeem, or
otherwise acquire any of the Parent stock issued in the Exchange, either
directly or through any transaction, agreement or arrangement with any
other person (excluding any fractional shares of the Parent Common Stock
exchanged for cash in the Exchange). The Company has no plan or intention,
nor is the Company aware of any plan or intention on the part of any person
related to the Company (as defined in Treasury Regulation Section
1.368-1(e)) to acquire or redeem any of the Parent stock issued in the
Exchange, either directly or through any transaction, agreement or
arrangement with any other person. For purposes of this representation
letter, a person is considered to own or acquire stock owned or acquired
(as the case may be) by a partnership in which such person is a partner in
proportion to such person's interest in the partnership.

            8. The Company has not made, and does not have any plan or
intention to make, any distributions prior to, in contemplation of or
otherwise in connection with, the Exchange (other than dividends made in
the ordinary course of business).

            9. The Company is not aware of any plan or intention on the
part of Parent to, following the Exchange, liquidate the Company, merge the
Company with or into another corporation in which the Company is not the
survivor, sell or otherwise dispose of shares of the Company, cause the
Company to distribute to Parent or any of its subsidiaries any assets of
the Company or the proceeds of any borrowings incurred by the Company or
cause the Company to sell or otherwise dispose of any of its assets, except
for dispositions made in the ordinary course of business, transfers of
assets permitted under Section 368(a)(2)(C) of the Code or Treasury
Regulation Section 1.368-1(d) or 1.368-2(k), and the sale of Cleveland
District Cooling Corporation, Cleveland Thermal Energy Corporation, Mid
America Energy Resources and Indianapolis Campus Energy, or the assets of
each, for an amount of cash or other consideration with a fair market value
equal to that of the assets sold in exchange therefor.

            10. Except as specifically contemplated under Section 6.8 of
the Exchange Agreement, the Company and its shareholders will pay their
respective expenses, if any, incurred in connection with the Exchange. The
Company has neither paid (directly or indirectly) nor agreed to assume any
expense or other liability, whether fixed or contingent, incurred or to be
incurred by any holder of Company Stock in connection with or as part of
the Exchange or any related transactions.

            11. The Company shall pay all Transfer Taxes attributable to
the Exchange out of the Company's own funds (and not out of funds provided,
directly or indirectly, by Parent).

            12. Except as specifically set forth in Section 3.2 of the
Exchange Agreement, immediately prior to the time of the Exchange, the
Company will not have outstanding any warrants, options, convertible
securities or any other type of right pursuant to which any person could
acquire Company stock. Simultaneously with the Exchange, all outstanding
warrants, options, convertible securities, and related stock appreciation
rights, if any, to purchase or acquire a share of Company stock granted
under employee incentive or benefits plans, programs or arrangements and
non-employee director plans presently maintained by the Company, together
with all other outstanding awards granted under such plans, will be
canceled or converted into similar instruments of Parent. Immediately
following the Exchange, the only class of Company stock outstanding will be
the Company Common Stock held by Parent.

            13. No assets of the Company have been sold, transferred or
otherwise disposed of which would prevent Parent or members of its
"qualified group" from continuing the "historic business" of the Company or
from using a significant portion of the "historic business assets" of the
Company in a business following the Exchange (as such terms are defined in
Treasury Regulation section 1.368-1(d)).

            14.   The Company is not an investment Company as defined in
Section 368(a)(2)(F)(iii) and (iv) of the Code.

            15. The Company will not take, and, to the knowledge of the
Company, there is no plan or intention by stockholders of Company to take,
any position on any Federal, state or local income or franchise tax return,
or take any other tax reporting position, that is inconsistent with the
treatment of the Exchange as a reorganization within the meaning of Section
368(a) of the Code, unless otherwise required by a "determination" (as
defined in Section 1313(a)(1) of the Code) or by applicable state or local
tax law (and then only to the extent required by such applicable state or
local tax law).

            16. None of the compensation received (or to be received) by
any stockholder-employee or stockholder-independent contractor of the
Company is (or will be) separate consideration for, or is (or will be)
allocable to, any of such person's Company Common Stock surrendered in the
Exchange. None of the Parent Stock that will be received by any
stockholder-employee or stockholder-independent contractor of the Company
in the Exchange represents separately bargained for consideration which is
allocable to any employment agreement or arrangement. The compensation paid
to any stockholder-employee or stockholder-independent contractor pursuant
to any agreement entered into in connection with the Exchange will be for
services actually rendered, will be commensurate with amounts paid to third
parties bargaining at arm's length for similar services or covenants, and
will be determined independent of the determination of the consideration to
be paid for the Company Common Stock.

            17. There is no intercorporate indebtedness existing between
Parent (or any of its subsidiaries) and the Company (or any of its
subsidiaries) that was issued, acquired or will be settled at a discount.

            18. The Company is not under the jurisdiction of a court in a
Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the
Code.

            19. To the knowledge of the Company, neither Parent nor any
person related to the Parent (within the meaning of Treasury Regulation section
1.368-1(e)(3)) owns, directly or indirectly, nor have they owned during the
past five years, directly or indirectly, any shares of the stock of the
Company.

            20. The Company will satisfy the information reporting
requirements of Treasury Regulation section 1.368-3 with respect to the
Exchange.

            21. The Exchange Agreement, the Registration Statement and the
other documents described in the Registration Statement (including all
exhibits and attachments thereto) represents the entire understanding
between the Parent and the Company regarding the Exchange, and there are no
other written or oral agreements between the Parent and the Company
regarding the Exchange.

            22. The Exchange is being undertaken for purposes of enhancing
the business of the Company and for other good and valid business purposes
of the Company.

            23. On the date of the Exchange, the fair market value of the
assets of the Company will exceed the sum of its liabilities, plus the
amount of liabilities, if any, to which such assets are subject.

            24. No holders of Company stock have appraisal or dissenters'
rights with respect to the Exchange under any applicable law.

            25.   The undersigned is authorized to make all the
representations set forth herein on behalf of the Company.

            The undersigned acknowledges that (i) the opinions to be
delivered pursuant to Sections 7.2(j) and 7.3(d) of the Exchange Agreement
will be based on the accuracy and completeness of the representations set
forth herein and on the accuracy and completeness of the representations
and warranties and the satisfaction of the covenants and obligations
contained in the Exchange Agreement and the various other documents related
thereto, and (ii) such opinions will be subject to certain limitations and
qualifications including that it may not be relied upon if any such
representations or warranties are not accurate and complete or if any of
such covenants or obligations are not satisfied in all material respects.
The Company understands that Cravath, Swaine & Moore and Skadden, Arps,
Slate, Meagher & Flom LLP have not undertaken to independently verify the
facts providing the basis of this letter nor have they been asked to do so.

            The undersigned acknowledges that such opinions will not
address any tax consequences of the Exchange or any action taken in
connection therewith except as expressly set forth in such opinions.


                                    Very truly yours,

                                    IPALCO Enterprises, Inc.

                      Form of Parent Affiliate Letter


Dear Sirs:

                  The undersigned, a holder of shares of Parent Common

Securities Act or Accounting Series Releases 130 and 135, as amended, of
the SEC (the "Releases"), although nothing contained herein should be
construed as an admission of such fact.

                  The undersigned hereby represents to and covenants with
Parent that the undersigned will not, from the date hereof, reduce its risk
(within the meaning of the Releases) with respect to any Parent Common

carefully read this letter and understands the requirements hereof and the
limitations imposed upon the distribution, sale, transfer or other
disposition of Parent Common Stock and (ii) the receipt by Parent of this
letter is an inducement and a condition to Parent's obligations to

                                                 Very truly yours,






Dated:


                                                                    EXHIBIT D-2


                      Form of Company Affiliate Letter


Dear Sirs:

                  The undersigned refers to the Agreement and Plan of Share
Exchange (the "Share Exchange Agreement") dated as of July 15, 2000, among
The AES Corporation, a Delaware corporation, and IPALCO Enterprises, Inc.,
an Indiana corporation. Capitalized terms used but not defined in this
letter have the meanings given to such terms in the Share Exchange
Agreement.

                  The undersigned, a holder of shares of Company Common
Stock, is entitled to receive in connection with the Share Exchange shares
of Parent Common Stock. The undersigned acknowledges that the undersigned
may be deemed an "affiliate" of the Company within the meaning of Rule 145
("Rule 145") promulgated under the Securities Act or Accounting Series
Releases 130 and 135, as amended, of the SEC (the "Releases"), although
nothing contained herein should be construed as an admission of such fact.

                  If in fact the undersigned were an affiliate under the
Securities Act, the undersigned's ability to sell, assign or transfer the
Parent Common Stock received by the undersigned in exchange for any shares
of Company Common Stock pursuant to the Share Exchange may be restricted
unless such transaction is registered under the Securities Act or an
exemption from such registration is available. The undersigned (i)
understands that such exemptions are limited and (ii) has obtained advice
of counsel as to the nature and conditions of such exemptions, including
information with respect to the applicability to the sale of such
securities of Rules 144 and 145(d) promulgated under the Securities Act.

                  The undersigned hereby represents to and covenants with
Parent that the undersigned will not sell, assign or transfer any of the
Parent Common Stock received by the undersigned in exchange for shares of
Company Common Stock pursuant to the Share Exchange except (i) pursuant to
an effective registration statement under the Securities Act or (ii) in a
transaction that, in the opinion of counsel (the reasonable fees of which
counsel will be paid by Parent) or as described in a "no-action" or
interpretive letter from the Staff of the SEC, is not required to be
registered under the Securities Act.

                  The undersigned further represents to and covenants with
Parent that (i) the undersigned will not, between the date hereof and the
Closing Date, reduce its risk (within the meaning of the Releases) with
respect to any shares of Company Common Stock held by it and (ii) the
undersigned will not reduce its risk (within the meaning of the Releases)
with respect to, any Parent Common Stock received by it in the Share
Exchange until after such time as a report (the "Report") including results
covering at least 30 days of combined operations of the Company and Parent
have been published by Parent. Parent will publish the Report as promptly
as practicable following the Share Exchange and in any event within 30 days
following the end of the first full calendar month following the Share
Exchange.

                  In the event of a sale or other disposition by the
undersigned pursuant to Rule 145 of Parent Common Stock received by the
undersigned in the Share Exchange, the undersigned will supply Parent with
evidence of compliance with such Rule, in the form of a letter in the form
of Annex I hereto and the opinion of counsel or no-action letter referred
to above. The undersigned understands that Parent may instruct its transfer
agent to withhold the transfer of any Parent Common Stock disposed of by
the undersigned, but that upon receipt of such evidence of compliance the
transfer agent shall effectuate the transfer of the Parent Common Stock
sold as indicated in the letter.

                  The undersigned acknowledges and agrees that appropriate
legends will be placed on certificates representing Parent Common Stock
received by the undersigned in the Share Exchange or held by a transferee
thereof, which legends will be removed by delivery of substitute
certificates upon receipt of an opinion in form and substance reasonably
satisfactory to Parent from counsel (the reasonable fees of which counsel
will be paid by Parent) to the effect that such legends are no longer
required for purposes of the Securities Act.

                  The undersigned acknowledges that (i) the undersigned has
carefully read this letter and understands the requirements hereof and the
limitations imposed upon the distribution, sale, transfer or other
disposition of Parent Common Stock and (ii) the receipt by Parent of this
letter is an inducement and a condition to Parent's obligations to
consummate the Share Exchange.

Dated:



                                                                        ANNEX I
                                                                   TO EXHIBIT D
