          Amendment No. 3 to the Application previously filed in this proceeding
is hereby amended and restated to read as follows:

           INTRODUCTION AND REQUEST FOR ADDITIONAL COMMISSION ACTION

          Chevron Corporation ("Chevron Corp."), its wholly-owned subsidiary,
Chevron U.S.A. Inc. ("Chevron USA"), n1 and Illinova Corporation ("Illinova" and
collectively with Chevron Corp. and Chevron USA, the "Applicants") hereby file
an application for an order from the United States Securities and Exchange
Commission (the "Commission") finding that, upon the consummation of the merger
transactions described in Item 1.B below (the "Transaction"), Chevron Corp. and
Chevron USA shall be exempt from all provisions of the Public Utility Holding
Company Act of 1935 (the "Act") other than Section 9(a)(2), pursuant to Section
3(a)(3) of the Act.

ITEM 1.    DESCRIPTION OF PROPOSED TRANSACTION

          For purposes of the relief requested herein, Applicants provide the
following description of the Transaction.

A.  THE PARTICIPANTS

          The Transaction involves merging a company with energy-related
operations, exempt operations, and no public-utility company operations (Dynegy
Inc.) with an exempt public-utility holding company (Illinova) which has limited
exempt and energy-related operations. Chevron's role has been to accommodate the
Transaction, which was initiated by Dynegy Inc. and Illinova.

          1.  CHEVRON CORPORATION

          Chevron Corp., a Delaware corporation, manages its investments in, and
provides administrative, financial and management support to, domestic and
foreign subsidiaries and affiliates that engage in fully-integrated petroleum
and chemical operations in the United States and approximately 90 other
countries. n2 Chevron Corp.'s stock is listed on the New York, Chicago and
Pacific Stock Exchanges, and it is a reporting company under the Securities
Exchange Act of 1934, as amended.

- ------------
  n1 Except where the context otherwise requires, Chevron Corp. and Chevron USA
are collectively referred to herein as "Chevron."

  n2 Chevron Corp.'s petroleum operations consist of exploring for, developing,
and producing crude oil and natural gas; refining crude oil into finished
petroleum products; marketing crude oil, natural gas, and the many products
derived from petroleum; and transporting crude oil, natural gas, and petroleum
products by pipelines, marine vessels, motor equipment, and railcar. The
chemical operations of Chevron Corp. include the manufacture and marketing of a
wide range of chemicals for industrial uses. Chevron Corp. is currently in the
process of selling its remaining interests in coal mining operations.


                                       1
<PAGE>

          Chevron Corp. had annual revenues in 1998 of over $30 billion, with
average annual revenues over the last three years (1996-1998) of $38.8 billion.
These revenues yielded $1.34 billion net income in 1998, with a three-year
average net income of $2.4 billion.

          Chevron Corp.'s largest business segments are its exploration and
production operations and its refining, marketing and transportation operations.
The petroleum activities of the company are widely dispersed geographically,
with upstream and downstream operations in the United States and Canada, and
upstream operations in Nigeria, Angola, Australia, the United Kingdom,
Kazakhstan, Thailand, Indonesia, Norway, Republic of Congo, China and Venezuela.
The company's chemical operations are concentrated in the United States, but
also include manufacturing facilities in France, Japan, Brazil, Singapore and
Mexico. Additionally, chemical manufacturing facilities are under construction
in China and Saudi Arabia.

          Chevron Corp. owns 100% of Chevron USA, a Pennsylvania corporation,
which conducts operations worldwide through its various divisions. Chevron USA's
principal business activity is in its domestic upstream division that engages in
the exploration and production of crude oil, natural gas liquids, and natural
gas in the United States, and its domestic downstream division that engages in
the business of refining, marketing and transporting gasoline and other refined
products in the United States. Chevron USA's net income for 1998 for United
States operations was approximately $1 billion. Chevron USA owns approximately
29% of the outstanding common and preferred stock of Dynegy Inc. ("Dynegy"), a
leading provider of energy products and services in North America and the United
Kingdom. The vast majority of Chevron Corp.'s natural gas production, as well as
the natural gas liquids extracted from the gas, are committed to Dynegy under
various commercial agreements. In 1998, 73% of Chevron Corp.'s worldwide sales
of natural gas were made to Dynegy.

          Neither Chevron Corp. nor Chevron USA currently has any public-utility
company subsidiaries, neither is an affiliate of a public-utility company, and
no part of either company's income is derived from the operations of a public-
utility company as defined by the Act. n3

          Additional information regarding Chevron Corp. and its subsidiaries is
set forth in the following documents, each of which is incorporated herein by
reference:

- ------------
  n3 Chevron Chemical Company ("Chemical"), a wholly-owned subsidiary of Chevron
USA, is considering the purchase from Entergy Gulf States ("Entergy") of its
Bunch Gully (138 KV) Substation, currently dedicated to supplying the power load
at Chemical's Orange, Texas plant. This purchase would eliminate monthly
added facilities payments and enable Chemical to control the substation
supplying the Orange plant. Entergy would require unrestricted use of the
through bus at no cost, which could result in Chemical's receiving adjustments
to certain fees charged by Entergy to the extent Entergy's use of the bus
increases maintenance costs or limits Chemical's use. As the substation is
integral to the Entergy grid, Entergy is likely to condition the sale to
Chemical on Entergy being able to flow power from time-to-time from one Entergy
transmission line through Chemical's 138 KV substation to a second Entergy
transmission line in order to supply other Entergy customers, without imposition
of any wheeling fee by Chemical. The documents are also likely to include a
"regulatory-out" provision requiring that, should any governmental authority
find the sale not in the public interest, the sale must be reversed or other
arrangements made.

               1999, filed on November 4, 1999.

          2.  DYNEGY INC.

          Dynegy, a Delaware corporation, is actively engaged in the marketing
and trading of natural gas, natural gas liquids, electricity and coal. It also
owns subsidiaries that develop, own and operate power generation projects that
are exempt from the Act, including Exempt Wholesale Generators ("EWGs") and
companies with interests in qualifying facilities under the Public Utility
Regulatory Policies Act of 1978. Dynegy has no public-utility company
operations, subsidiaries or affiliates.

          Dynegy maintains its principal place of business in Houston, Texas.
The company's stock is listed on the New York Stock Exchange. In addition to
Chevron USA, Dynegy has two industrial shareholders: NOVA Gas Services (U.S.)
Inc., a Delaware corporation ("NOVA"), and BG Holdings, Inc., a Delaware
corporation ("BG"), each of which owns approximately 25% of the outstanding
voting stock of Dynegy. n4 Of the remaining outstanding voting stock of Dynegy,
11% is owned by management and the balance is publicly owned.

          On August 31, 1996, Chevron USA formed a strategic combination with
NGC Corporation ("NGC"), Dynegy's predecessor, whereby substantially all of
Chevron USA's mid-stream natural gas marketing and natural gas processing and
natural gas liquids marketing operations were transferred to NGC's operations in
exchange for stock constituting the shares of Dynegy which Chevron now holds
(the "Chevron Combination"). Effective July 1, 1997, NGC acquired Destec Energy,
Inc., an independent power producer. During 1998, NGC changed its name to Dynegy
Inc. Pursuant to agreements entered into as part of the Chevron Combination,
Dynegy has the obligation to purchase and the right to market substantially all
of the natural gas and gas liquids produced by Chevron USA, except those
produced in Alaska. In addition, pursuant to other agreements, Dynegy supplies
natural gas and natural gas liquids feedstocks to Chevron's refineries and
chemical plants in the United States. n5

- ------------
  n4 NOVA is an indirect, wholly-owned subsidiary of NOVA Chemicals Corporation,
a Canadian corporation. BG is an indirect, wholly-owned subsidiary of BG plc, a
British corporation.

  n5 Chevron Corp. also enjoys certain business opportunities and benefits under
an Operating Agreement (the "Caltex Operating Agreement") with Texaco Inc.
("Texaco"), concerning Caltex Petroleum Corporation, a Delaware corporation
("Caltex"), that is a joint venture of Chevron Corp. and Texaco. Dynegy has
entered into a Scope of Business Agreement with Chevron Corp. relating to the
Caltex Operating Agreement, pursuant to which Dynegy and Chevron Corp.
facilitate discussion of Caltex-related commercial opportunities suitable for
exploitation in whole or in part by Dynegy. The Certificate of Incorporation of
Dynegy contains (and the Articles of Incorporation of New Dynegy will contain)
provisions precluding Dynegy from effecting a sale of petroleum products (other
than natural gas) intended for consumption or resale in certain parts of Africa,
most of Asia, Australia and other areas of the Pacific west of the International
Date Line, except pursuant to the process established by the Scope of Business
Agreement or as Chevron may otherwise approve in a shareholder vote.
Registration Statement on Form S-4 under the Securities Act of 1933 of Midstream
Combination Corp. (Registration No. 333-09419) at 25, 53, filed with the
Commission on August 1, 1996.

                                       3
<PAGE>

          Chevron understands that, as is the case with other industry
participants, Dynegy is presently pursuing an integrated wholesale energy
business strategy based on the convergence of energy markets. This strategy
exploits the marketing, trading and hedging opportunities existing in the
natural gas and power markets, which can be most effectively realized by the
control and optimization of related physical assets. Dynegy treats its gas and
power marketing and power generation businesses as an integrated unit. Dynegy
considers that: (i) ownership or control of merchant generation, or "Btu
Conversion" capacity, when coupled with Dynegy's national wholesale gas and
power marketing operations, creates a wide range of value-creation
opportunities; (ii) Dynegy's wholesale trading and marketing franchise adds
value to its generation assets by providing national market access, market
infrastructure and intelligence, risk management and arbitrage opportunities,
fuel management and procurement expertise and transmission expertise for inputs
(gas) and outputs (power); (iii) generation capacity adds value to Dynegy's
wholesale trading and marketing franchise by providing a source of reliable
power, an enhanced ability to structure innovative new products and services for
customers, and a market for natural gas; and (iv) by aligning its operations
with the power generation base and experience of Illinova, Dynegy expects to
enhance the value of its power generation and power marketing capabilities.

          Additional information regarding Dynegy and its subsidiaries is set
forth in the following documents, to which reference is made:

          (i)   Annual Report on Form 10-K of Dynegy Inc. (Commission File
                No. 1-11156) for the fiscal year ended December 31, 1998, filed
                on March 30, 1999;

          (ii)  Current Report on Form 8-K of Dynegy Inc. (Commission File

                "New Dynegy Registration Statement"); and

          (iv)  Quarterly Report on Form 10-Q of Dynegy Inc. (Commission File

                filed on November 15, 1999.

          3.  ILLINOVA CORPORATION

          Illinova Corporation  ("Illinova") is a public-utility holding company
exempt from  registration  under Section  3(a)(1) of the Act. It is incorporated
and maintains its principal place of business in the State of Illinois,  and its
common  stock is listed on the New York and Chicago

                                       4
<PAGE>

Stock Exchanges. Illinova owns six active subsidiaries: Illinois Power Company,
a combination electric and gas public-utility company ("Illinois Power"),
Illinova Generating Company ("Illinova Generating"), Illinova Energy Partners,
Inc. ("Illinova Energy"), Illinova Insurance Company ("Illinova Insurance"),
Illinova Power Marketing, Inc. ("Illinova Marketing"), and Illinova Business
Enterprises ("Illinova Business").

          Illinova's revenues for 1998 were $2.43 billion, but resulted in a net
loss of $1.38 billion, largely attributable to a loss sustained by Illinois
Power. In 1998, approximately 73% of Illinova's operating revenues were derived
from Illinois Power's sale, transmission and distribution of electricity, and
12% of Illinova's operating revenues were derived from Illinois Power's sale and
transportation of natural gas. Approximately 15% of Illinova's operating
revenues came from its other, diversified enterprises in 1998.

          Illinois Power is an Illinois corporation and Illinova's principal
public-utility company subsidiary. It is engaged in the generation, transmission
and distribution of electric energy and the sale of electric energy at wholesale
and retail in the State of Illinois. Illinois Power also owns facilities for the
distribution of natural gas and is engaged in the sale of natural gas at retail.
Illinois Power provides traditional utility service subject to state regulation
to approximately 570,000 retail electric and 400,000 retail gas distribution
customers located throughout central Illinois, and also transmits and sells
power at wholesale subject to the jurisdiction of the Federal Energy Regulatory
Commission ("FERC"). Illinova's electric utility and gas utility systems operate
on an integrated basis. All of the company's utility assets are located in the
State of Illinois. Illinois Power is regulated by the Illinois Commerce
Commission ("ICC") and the FERC. n6

          Illinova Marketing is an Illinois corporation and a wholly-owned
electric public-utility company subsidiary of Illinois. It owns and operates
3,812 MW of fossil-fired electric power generating capacity located in the State
of Illinois, formerly owned by Illinois Power. This generation will be utilized
predominantly to meet the power requirements of Illinois Power during a
competition transition period established by Illinois law. On July 8, 1999, the
ICC approved the restructuring of Illinois Power in this fashion. n7 The FERC
authorized these asset transfers and wholesale power sales in two recent orders.
n8 Illinova intends to convert Illinova Marketing to an EWG within the year
following closing of the Transaction.

          Illinova Generating is Illinova's wholly-owned independent power
subsidiary and is not a public-utility company under the Act. Illinova
Generating currently owns interests in EWGs and in qualifying facilities located
throughout North America, as well as interests in several

  n6 Illinois Power recently completed the sale to Amergen Energy Company,
L.L.C. of the 930 MW nuclear generating facility located in Clinton, Illinois
(the "Clinton Facility") referred to in Amendment No. 3 to this Application. See
Amendment No. 3 to Application on Form U-1/A under the Public Utility Holding
Company Act of 1935 of Chevron Corporation, Chevron U.S.A. Inc. and Illinova
Corporation (Dec. 23, 1999) at 4.

generation facilities located outside of North America. The North American
facilities total 821 MW with an 830 MW plant under construction.

          Illinova Generating owns 20% of the stock of Electric Energy
Incorporated ("EEInc"), which the Commission has classified as a public-utility
company for certain purposes under the Act. The revenues and net income of EEInc
are not material to Illinova's total public-utility revenues and income. EEInc
was incorporated in 1950 for the purpose of generating electricity for sale to
the United States government nuclear processing plant near Paducah, Kentucky.
Its principal place of business is Joppa, Illinois. Approximately 70% of the
revenues associated with the Joppa plant are derived from sales to the United
States Department of Energy under a contract that extends until 2005. Sponsoring
utilities, including Illinois Power, purchase power in excess of the federal
government's requirements. The Commission has for many years recognized this
project as sui generis and that EEInc "does not itself sell electricity to
private consumers of the type the Act is designed to protect and does not have
any securities in the hands of public investors." n9

          Illinova Energy is Illinova's wholly-owned subsidiary that engages in
the brokering and marketing of electric power and gas, and the development and
sale of energy-related services to the competitive unregulated energy market
throughout the United States and Canada. Illinova Energy owns interests in
several gas marketing companies. It is not a public-utility company under the
Act. n10

          On December 16, 1997, the State of Illinois enacted the Electric
Service Customer Choice and Rate Relief Law of 1997, which introduces retail
competition and customer choice to electricity consumers in the State of
Illinois. n11 The legislation adopts a comprehensive approach to creating a
market mechanism to provide electric energy to consumers. The law contains the
following key provisions:

          Affiliate Relationships: The ICC is required to, and has, adopted
          rules governing the relationships between electric utilities and their

          by the electric utility to its affiliates and to alternative retail

          Functional Separation / Code of Conduct: The ICC is required to adopt
          standards of conduct for electric utilities and is promulgating rules
          for the functional separation of generation services and delivery
          services. The restructuring of

          Illinova approved by the ICC n12 to separate power generation from
          power delivery was designed to be consistent, and is consistent, with
          the new Illinois and FERC policies requiring separation of these
          functions.

          Rate Decreases: The law provides Illinois Power's residential
          customers a 15% decrease in base electric rates beginning August 15,
          1998, and an additional 5% decrease beginning May 1, 2002.

          Rate Freeze: The law freezes rates for bundled electric service
          through January 1, 2005 (with the exception of the mandatory rate
          decreases discussed above), unless the utility's earned rate of return
          on common equity falls below the 30-year Treasury bond rate for two
          consecutive years. This rate freeze generally forces public-utilities
          to absorb fuel and purchased power cost increases. It also provides a
          vehicle for the recovery of transition costs (or "stranded" costs)
          minus statutorily prescribed mitigation factors during the transition
          period established by Illinois law. Thus, the rates of Illinois Power
          under the rate freeze include fuel, purchased power and transition
          cost recovery.

          Retail Choice: Since October 1, 1999, the following categories of
          retail customers have been eligible to choose their electricity
          supplier: (i) customers with a demand greater than 4 MW at a single
          site; (ii) customers under common ownership with ten or more sites in
          a service area which aggregate to at least 9.5 MW in demand; and (iii)
          customers comprising one-third of the remaining non-residential load.
          The rest of the non-residential customer group will be eligible for
          direct access by December 31, 2000. All residential customers will
          have direct access by May 2002. For Illinois Power, this means that
          non-residential customers representing 53% of its total current retail
          electric sales volume were eligible to select an alternate generation
          service supplier on October 1, 1999 (subject to pre-existing contract
          term requirements). All non-residential customers, representing 73% of
          Illinois Power's total current electric sales volume, will be eligible
          to select an alternate generation service supplier at year- end 2000
          (subject to pre-existing contract term requirements).

          Delivery Service: Illinois Power is obligated to provide delivery
          service to customers eligible for direct access under tariffs approved
          by the ICC. The ICC also regulates the services provided by public
          utilities to alternative retail electric suppliers.

          ICC Oversight of Transmission And Distribution Reliability: The ICC
          must adopt regulations on transmission and distribution reliability.
          In addition, Illinois utilities must form or join an independent
          system operator.

          Sale or Transfer of Electric Utility Assets: During the transition
          period (1998-2004), electric utilities can sell or transfer assets to
          affiliated or unaffiliated entities

          pursuant to an ICC review process which must be completed within 90
          days and which establishes specific criteria for ICC review.

          Recent federal and state regulatory initiatives have the following
implications for Illinois Power and Illinova:

          . Illinois Power is required to maintain transmission interconnections
            with numerous major regional electric utilities and power supply
            regions and provide open access transmission service.

          . Illinois Power is ceding operational control of its transmission
            system to a regional Independent System Operator.

          . Illinois Power is required to implement open access transmission on
            its distribution system to facilitate energy competition for retail
            electric customers and to provide nondiscriminatory delivery service
            to its retail customers.

          . Illinois Power is required to implement retail rate reductions and
            to maintain a retail rate freeze.

Illinois Power estimates that the regulatory changes initiated by the FERC and
the State of Illinois and Illinois Power's resulting restructuring will reduce
its gross utility plant account from the 1998 level of $6.168 billion n13 to
$2.8 billion in 2000 n14 and its electric revenues from the 1998 level of
$1.781 billion n15 to $1.154 billion in 2000. n16 Over half of the year 2000
revenues will constitute recovery of regulatory transition costs and purchased
power costs. As a result of state and federal restructuring of energy markets,
the ability of Illinova to compete effectively has become essential to its
success as a business enterprise and to its ability to attract capital at a
reasonable cost.

          4.  ENERGY CONVERGENCE HOLDING COMPANY ("NEW DYNEGY")

          Energy  Convergence  Holding  Company  ("New  Dynegy")  is an Illinois
corporation formed for the purposes of effectuating the Transaction. n17 New
Dynegy currently has no material assets and no public-utility assets,
subsidiaries, or affiliates. Additional information regarding New Dynegy is set
forth in the New Dynegy Registration Statement, which is incorporated herein by
reference.

B.  THE TRANSACTION

          The Transaction involves a combination of Dynegy and Illinova through
a series of mergers, resulting in the formation of New Dynegy as an Illinois
public-utility holding company. Chevron and Illinova understand that New Dynegy
separately filed, under Rule 2 of the Commission's regulations, notification of
its status as a holding company exempt under Section 3(a)(1) of the Act on the
same grounds as presently claimed by Illinova. n18 New Dynegy currently has two
wholly-owned subsidiaries, an Illinois corporation n19 and a Delaware
corporation, n20 that will serve as acquisition companies. In the Transaction,
Illinova will be merged with the Illinois acquisition company with Illinova
surviving the merger, and Dynegy will be merged with the Delaware acquisition
company with Dynegy surviving the merger. As a result, upon completion of the
Transaction, Illinova and Dynegy will be wholly-owned subsidiaries of New
Dynegy. The parties intend to simplify the New Dynegy holding company structure
after the Transaction by eliminating one tier in the holding company structure.
n21

          In the Transaction, each shareholder of Dynegy (except Chevron USA)
will elect to receive either (i) cash in the amount of $16.50 or (ii) 0.69
shares of New Dynegy Class A

Common Stock n22 for each share of Dynegy common stock. n23 Chevron has agreed
to receive all stock in the Transaction. BG's parent corporation and NOVA have,
directly or indirectly, elected to receive all cash. However, only approximately
40% of the shares of Dynegy common stock will be exchangeable for cash, and the
remaining shares of Dynegy will be exchangeable for shares of New Dynegy Common
Stock or Series A Preferred Stock. n24 This will result in conversion of a
maximum of approximately 67.6 million shares of Dynegy common stock into cash.
The amount of cash available will be insufficient to satisfy completely cash
elections, and the cash will be prorated among shareholders electing to receive
cash. For each 100 shares of Dynegy common stock for which Dynegy shareholders
elect to receive cash, they will receive cash consideration with respect to no
less than 63 shares of Dynegy common stock and no more than 84 shares of Dynegy
common stock. The consideration for the balance of the Dynegy common stock will
be New Dynegy Class A Common Stock. Each share of Illinova common stock will be
exchangeable for one share of New Dynegy Class A Common Stock. As a result,
slightly more than one-half of New Dynegy's voting stock will be held by former
Dynegy shareholders.

          Although BG's parent corporation and NOVA have elected to receive all
cash, the 40% limit on the cash portion of the merger consideration results in
their receiving at least some portion of their consideration in the form of
Series A Preferred Stock. The amount of Series A Preferred Stock that BG and
NOVA will receive is dependent upon the number of shares held by the public
shareholders that are tendered for cash. To facilitate the Transaction and
assist NOVA and BG's parent corporation in liquidating their investment in
Dynegy, Chevron USA has agreed to purchase from New Dynegy additional shares of
New Dynegy's Class B Common Stock for an aggregate purchase price of between
$200 and $240 million. To the extent that BG's parent corporation and NOVA would
otherwise receive less than 75% cash in exchange for shares of Dynegy common
stock, Chevron USA has agreed to increase its investment, up to a maximum of
$240 million. As a result of these repurchase transactions, Chevron USA's
ownership interest in New Dynegy upon completion of the Transaction will be
approximately 28%.

          Pursuant to an amendment to New Dynegy's Articles of Incorporation
(which has been filed with the State of Illinois) and a related shareholder
agreement among Dynegy, New Dynegy, Illinova and Chevron USA dated June 14, 1999
(the "Shareholder Agreement"), so long as Chevron USA owns at least 15% of New
Dynegy Common Stock, Chevron USA shall be

- ------------
  n22 The New Dynegy Common Stock consists of Class A Common Stock and Class B
Common Stock. As used herein, the term "Common Stock" refers to the New Dynegy
Class A and Class B Common Stock collectively.

  n23 Each such Dynegy shareholder will receive cash for any fractional share
regardless of the shareholder's election.

  n24 NOVA and BG will each receive New Dynegy Series A Preferred Stock. The
management and the public shareholders of Dynegy will receive New Dynegy Class A
Common Stock that will be registered under the Securities Act of 1933, as
amended (the "Securities Act"), and listed on the New York Stock Exchange.
Chevron USA will receive only Class B Common Stock and will own no Class A
Common Stock unless and until its Class B Common Stock is converted in
accordance with the New Dynegy Articles of Incorporation. The issuance of Class
B Common Stock to Chevron USA will be a transaction exempt from registration
under the Securities Act and the New Dynegy Class B Common stock is otherwise
subject to the federal securities laws. The terms of all of the issuances of New
Dynegy securities in the Transaction have been disclosed to the public and to
the shareholders of Dynegy and Illinois in the New Dynegy Registration Statement
filed with the Commission.

                                       10
<PAGE>

entitled to elect of three of the fourteen members of the New Dynegy Board of
Directors as Chevron USA's representatives (the "Chevron Directors") through
voting its Class B Common Stock. Because the holders of Class A Common Stock
vote as a separate class for the other eleven directors, Chevron USA has no
voice in the selection of such directors and will have no representative on New
Dynegy's Nominating Committee, which will propose such directors for election by
the holders of Class A Stock. When Chevron USA ceases to own at least 15% of New
Dynegy Common Stock, its New Dynegy Class B Common Stock will automatically
convert to New Dynegy Class A Common Stock and Chevron USA will no longer have
an exclusive right to elect three members of New Dynegy's Board of
Directors. n25

          Under New Dynegy's Articles of Incorporation, Chevron USA will not be
entitled to any more than three representatives on New Dynegy's Board as long as
it does not own more than 40% of the outstanding shares of New Dynegy. The
Shareholder Agreement provides that Chevron USA may not seek to acquire more
than 40% of the outstanding Common Stock of New Dynegy within one year after the
closing of the Transaction unless a third party seeks to acquire more than 15%
of such Common Stock. Thereafter, Chevron USA may only acquire more than 40% of
New Dynegy's Common Stock if it offers to acquire all of the outstanding voting
securities of New Dynegy. Any such offer by Chevron USA is subject to a detailed
process which gives the New Dynegy Board the ability to solicit competing offers
and obligates Chevron USA to sell its stake in the event it is not the winning
bidder. In consideration of the consequences to New Dynegy of a sale by Chevron
USA of its significant equity position, the Shareholder Agreement also imposes
restrictions on sales by Chevron USA of its shares in New Dynegy.

          To protect its strategic investment in New Dynegy, Chevron has
negotiated for certain provisions in the Articles of Incorporation of New
Dynegy. The Articles of Incorporation of New Dynegy carry forward and contain
provisions in Illinova's current articles of incorporation whereby, consistent
with Illinois corporate law and practice, a two-thirds vote will be required to
approve certain major transactions, including mergers, consolidations, sales of
assets, and liquidation. n26 In addition, if all Chevron Directors present at a
meeting vote to do so, they will have the ability under New Dynegy's Bylaws to
prevent New Dynegy from entering into certain transactions, so long as Chevron
USA owns New Dynegy Class B Common Stock, including (i) a sale of all or
substantially all of the liquids business or the gas marketing business of New
Dynegy so long as Chevron USA's long-term sale contracts with New Dynegy remain
in effect, and (ii) mergers, acquisitions, and other business combinations,
sales of businesses or assets, and major transactions, including joint ventures,
in which such transactions are valued over $1 billion or one-quarter of New
Dynegy's market capitalization, whichever is greater.

- ------------
  n25 The Articles of Incorporation of New Dynegy contain provisions for
cumulative voting by holders of the Class A Common Stock, generally, and
therefore Chevron USA might, even with less than 15% of New Dynegy Common Stock,
elect one or more members of New Dynegy's Board of Directors, but will have no
right to have its designees put forward as nominees and could not in such event
reasonably expect to elect more than three of the fourteen directors.

  n26 This will include, pursuant to Article 4 of the Articles of Incorporation
of New Dynegy, the preservation of certain ongoing strategic relationships under
the Caltex Operating Agreement, referenced in note 5, supra.

                                       11
<PAGE>

          While these are customary minority-protection rights, Chevron's
exercise of these rights is limited by other provisions. Under the Shareholder
Agreement, if Chevron USA exercises such rights twice within a 24-month period
or three times during any time period, either at the Board of Directors level or
on the shareholder level (other than to block changes to the constituent
instruments of New Dynegy which would materially affect such rights), New Dynegy
will have certain rights to purchase Chevron USA's shares or require Chevron USA
either to sell its shares of New Dynegy to a third party or to give up any
future blocking rights.

          All requisite corporate and shareholder approvals for the Transaction
have been obtained. Specifically, the Illinova Board of Directors approved the
Transaction on June 13, 1999, the Dynegy Board of Directors approved the
Transaction on June 14, 1999, and the shareholders of Illinova and Dynegy
approved the Transaction on October 11, 1999.

C.  REASONS FOR THE TRANSACTION

          Applicants wish to complete the Transaction in order to enhance the
efficiency of their operations consistent with applicable state and federal law,
and particularly state and federal regulatory changes implementing competitive
power generation and energy services and nondiscriminatory power delivery
services on an open access basis. n27

          Illinova seeks this business combination with Dynegy and to conduct
its public-utility operations as described herein in order to achieve a number
of financial, managerial and operating benefits that will position Illinova and
Illinois Power to compete in the increasingly competitive wholesale and retail
energy markets that have developed as a result of state and federal regulatory
change. In these restructured markets, Illinova expects that customers, whether
wholesale or retail, will purchase generated electricity separately from
transportation (transmission and distribution) services. In the case of
electricity, recently enacted Illinois legislation provides that customers will
have a choice in selecting their electricity provider, regardless of the
geographic proximity of the source of physical generation to the customer. It is
likely that the retail natural gas service market will soon function in a
similar manner.

          Illinova believes Dynegy will complement the utility operations of
Illinois Power and allow Illinova to combine its small energy trading operations
with the larger trading and marketing operations of Dynegy. A broader slate of
energy products and an effective marketing organization will permit Illinova to
remain competitive both for customers and for capital needed for exempt
operations and public-utility company operations. Maintaining a viable energy
business affiliated with Illinova's public-utility company operations will help
assure that consumers receive reliable service at competitive, market-driven
prices. The Transaction will result in an infusion of equity capital and the
formation by the merged firm of a robust energy generation and marketing
business. This development, occurring in the wake of Illinova's quasi-
reorganization, will enable Illinova to maintain competitive viability and the
ability to attract capital at a reasonable cost. Illinova believes that as a
result of the Transaction, the energy-

  n27 Each of Dynegy and Illinova were advised by and received the written
opinions of their respective financial advisors with respect to certain aspects
of the Transaction. See New Dynegy Registration Statement at 47-68, and
Appendices III, IV and V thereto.

                                       12
<PAGE>

related operations of New Dynegy will contribute significantly toward lowering
the overall cost of the restructured utility service received by consumers in
Illinois, and that Illinova will achieve improved earnings for investors. n28

          Dynegy believes that the Transaction will advance its strategic plan
through the addition of strategically located generation assets, which will
enable Dynegy to enhance its position as one of the nation's leading energy
merchants. Dynegy believes that a marketing enterprise such as Dynegy can
achieve a greatly enhanced value through a combination with a traditional
public-utility system that possesses a substantial installed base of generation
and substantial management experience with the ownership and operation of power
generation. n29

ITEM 2.    FEES, COMMISSIONS AND EXPENSES

          The fees, commissions and expenses to be paid or incurred, directly or
indirectly by all parties, in connection with the Transaction are estimated to
total approximately $46 million, including investment bankers' fees of
approximately $29 million.

ITEM 3.    APPLICABLE STATUTORY PROVISIONS

          Following the Transaction, Chevron USA will own more than 10% of the
voting securities of New Dynegy, raising the issue of whether Chevron Corp. and
Chevron USA are holding companies within the meaning of Section 2(a)(7) of the
Act absent an appropriate exemption.

          Section 3 of the Act provides that the Commission upon application
shall by order exempt any person from the provisions of the Act if such person
meets the requirements for any exemption contained in Sections 3(a)(1) through
3(a)(5) and if the exemption is not detrimental to the public interest or the
interest of investors or consumers. Section 3(a)(3) of the Act is applicable to
Chevron because, following the Transaction, Chevron will be "only incidentally"
a holding company, as it will remain primarily engaged and interested in non-
utility businesses, and will not derive a material part of its income from a
public-utility company. Accordingly, Chevron is entitled to an exemption from
all the provisions of the Act, except Section 9(a)(2), pursuant to Section
3(a)(3).

A.  THE SECTION 3(A)(3) EXEMPTION

          Following the Transaction, Chevron will be eligible for an exemption
under Section 3(a)(3) of the Act, which provides that the Commission:

          shall exempt any holding company, and every subsidiary
          company thereof as such, from any provision or provisions
          of [the Act], unless and except insofar as it finds the
          exemption detrimental

          to the public interest or the interest of investors and
          consumers, if -- . . . (3) such holding company is only
          incidentally a holding company, being primarily engaged or
          interested in one or more businesses other than the
          business of a public-utility company and (A) not deriving,
          directly or indirectly, a material part of its income from
          any one or more subsidiary companies, the principal
          business of which is that of a public-utility
          company . . . . n30

          Chevron's interest in New Dynegy will fit comfortably within the
exemption provided by Section 3(a)(3). Chevron's minority interest in New Dynegy
will arise solely because Chevron is willing to consent to and facilitate the
merger initiated and sought by Dynegy and Illinova, and not through efforts by
Chevron to engage directly or indirectly in the public-utility business or to
acquire a public-utility company or public utility holding company. Following
the Transaction, Chevron will remain primarily engaged and interested in its
non-utility petroleum and chemical businesses, and will not directly or
indirectly derive a material part of its income from Illinois Power, or any
other public-utility company.

          Compelling support for this Application - confirmation that Chevron
fits comfortably and squarely within the category of companies for which
Congress intended Section 3(a)(3) - is found in the Report to the Senate of the
Committee on Interstate Commerce, accompanying the bill that became the Act. n31
In the Senate Report, the Section 3(a)(3) exemption is described as applicable
where:

          [T]he company is not essentially in the utility field and
          either (A) gets no appreciable income from utilities, or
          (B) if it gets an appreciable income from utilities, it
          owns all the outstanding securities of those utilities so
          that they are not financed by the public but are
          essentially departments, rather than subsidiaries, of the
          parent company. n32

Chevron's position in New Dynegy will satisfy this test. For these reasons, and
as more fully discussed below, Chevron satisfies the requirements of the
exemption set forth in Section 3(a)(3) of the Act.

  n30 Act (S) 3(a)(3)(A). Subparagraph (B) of Section 3(a)(3) provides that the
materiality test described in subparagraph (A) is not applicable where
"substantially all of the outstanding securities of the subsidiary are owned,
directly or indirectly, by the holding company." See also Aluminum Co. of
America, Holding Co. Act Release No. 1669, 5 SEC 640 (Aug. 8, 1939). In light of
Chevron's minority ownership interest in New Dynegy, subparagraph (B) of Section
3(a)(3) is not applicable.

B.  CHEVRON IS ONLY INCIDENTALLY A HOLDING COMPANY, BEING PRIMARILY ENGAGED AND
    INTERESTED IN BUSINESSES OTHER THAN THAT OF A PUBLIC-UTILITY COMPANY.

          1.  THE TRANSACTION SATISFIES THE PLAIN LANGUAGE OF SECTION 3(a)(3).

          Chevron is a fully integrated petroleum company with no public-utility
company subsidiaries and no income derived from the operations of public-utility
companies as defined by the Act. As a result, Chevron presently is "primarily
engaged or interested in one or more businesses other than the business of a
public-utility company" within the meaning of Section 3(a)(3).

          Following the Transaction, Chevron will be "only incidentally" a
holding company. Chevron's status as a public-utility holding company will be an
incidental result of an arm's length transaction initiated by third parties,
independent of Chevron. The development of the Transaction shows that the
combination of Dynegy and Illinova is driven by the separate business needs of
the respective constituent companies, acting independently. At the time of
Chevron's original investment in Dynegy, Chevron did not intend or contemplate
the acquisition of an interest in any public-utility or public-utility holding
company. Chevron acquired its interest in Dynegy for the purpose of creating a
long-term alliance with a major energy trading company and to participate
through its equity ownership interest in Dynegy in gas and liquids marketing,
midstream services, and wholesale electric generation. Subsequent to Chevron's
acquisition of its interest, Dynegy determined that its combination with
Illinova will substantially enhance its marketing and trading operations and
give it access to significant resources in important geographic markets. By
allowing Dynegy to proceed with the Transaction, Chevron is facilitating
Dynegy's strategic expansion.

          This circumstance has nothing in common with an attempt to acquire a
public-utility company or its holding company. Chevron's post-Transaction
involvement in New Dynegy will focus on monitoring and protecting the value of
its original strategic investment, consisting of a minority ownership interest
proportional to the capital it has contributed. If Chevron were deemed a public-
utility holding company subject to registration as a result of the Transaction,
that could only be an incidental result of a business combination independently
sought by Dynegy and Illinova for reasons unrelated to Chevron's operations, and
not the result of any effort by Chevron to acquire or control a public-utility
company or its holding company. This is precisely the anomalous result Section
3(a)(3) appears designed to prevent.

          There is no Commission precedent denying a Section 3(a)(3) exemption
to a strategic shareholder of a holding company whose minority interest arises
solely as an unintended consequence of an arm's length merger transaction
initiated by third parties. Commission precedent denying exemptions under
Section 3(a)(3) appears in the context of efforts by applicants purposefully to
assemble and maintain vast holding company systems with many

                                       15
<PAGE>

majority controlled, public-utility company subsidiaries. n33 This Application
involves no such risk to the public policies of the Act.

          Granting the present exemption does not "open the door" closed fifty
years ago in the Commission's early application of the Section 3(a)(3) exemption
to block its use by large companies seeking to participate in the utility
business. In this case, Chevron's minority ownership in New Dynegy arises
through the merger of Dynegy and Illinova, whose public-utility company
activities have long been the subject of effective state regulation. That merger
is a result of the independently developed business purposes of Illinova and
Dynegy. In the context of that merger, although Chevron for its own independent
reasons, (unrelated to ownership of a public-utility), has maintained a
strategic investment in Dynegy, it is only coincidental that Dynegy's
combination with Illinova results in ownership by Chevron of a minority interest
in a newly formed public-utility holding company, New Dynegy. However, Chevron's
maintaining its strategic investment (i) will permit an otherwise beneficial
Transaction to occur, and (ii) as a result of Chevron's functional relationship
with the energy marketing business of Dynegy, will continue to serve the
interests and complement the operations of New Dynegy, including Illinova.

          2.  THERE WILL EXIST A FUNCTIONAL RELATIONSHIP BETWEEN CHEVRON'S
              BUSINESS AND THE PUBLIC-UTILITY OPERATIONS OF NEW DYNEGY.

          The Act does not set forth specific factors or circumstances which
define when a company is "only incidentally" a public-utility holding company.
In the years following enactment of the Act, the statutory language was glossed
by the additional requirement that the incidental nature of a company's status
as a holding company be demonstrated in part by the existence of a functional or
operational relationship between a subsidiary's utility operations and the
primary business of the holding company, even though the text of Section 3(a)(3)
does not contain such a requirement. n34 This gloss served to support denial of
exemptions in circumstances in which large multi-state holding company systems
whose operations had never been subjected to effective regulation sought to
avoid regulation under the Act while exploiting affiliate relationships with

- ------------
  n33 See, e.g., Cities Serv. Co., Holding Co. Release No. 2444, 8 SEC 318 (Dec.
23, 1940); Standard Oil Co., Holding Co. Release No. 3312, 10 SEC 1122 (Feb. 5,
1942). Although some of the Congressional debate cited by the Commission in
these older cases arguably supports a narrow interpretation of Section 3(a)(3),
the Senate Report states that the purpose of the Section 3(a) exemptions was to
"exempt those holding companies which the committee believes ought not to be
covered because of the fact, and to the extent, that they are either intrastate
in character or not essentially holding companies in the utility field." Senate
Report at 6 (emphasis added). This statement of the Committee (as opposed to
that of any individual member from the floor of Congress) supports an
interpretation of Section 3(a)(3) that would reasonably include companies such
as Chevron, which are not "essentially holding companies in the utility field."

  n34 The origin of the functional relationship test can be traced to remarks
made by Senator Wheeler which, importantly, were made in reference to a
proposed, but rejected, change in the wording "only incidentally a holding
company" to "only incidentally interested in a public-utility company." 79 Cong.
Rec. 8843-44 (1935). See also Cities Serv., 8 SEC 318; Standard Oil, 10
SEC at 1129. The Commission has never held that the examples used by Senator
Wheeler were exclusive, and in all events, the courts have held that Senator
Wheeler's explanations during the floor debate do not supplant the plain meaning
of the language of the Act. See Pacific Gas & Elec. Co. v. SEC, 127 F.2d 378,
382 (9th Cir. 1942), aff'd per curiam on reh'g, 139 F.2d 298 (9th Cir. 1943),
aff'd per curiam, 324 U.S. 826 (1945) (rejecting argument based upon explanation
articulated during floor debate that was at variance with the Act's plain
meaning).

public-utilities. Faced with these applications during the first twenty years of
its administration of the Act, the Commission articulated two requirements in
applying Section 3(a)(3) that the unregulated, multi-state systems routinely
failed to meet: (i) that there be a functional relationship between the non-
utility industry and the public-utility company it sought to own, and (ii) that
the public-utility company be small in size in an absolute sense. The Commission
explained the purpose of these conditions was to avoid making "exempt from the
operation of the Act a company which would otherwise be subject thereto, solely
by reason of its hybrid character." n35

          The considerations that led the Commission to apply a restrictive
gloss to Section 3(a)(3) in those cases do not apply to this Transaction because
(i) the Illinois Power public-utility system essentially operates in a single
state and is subject to effective state regulation, and (ii) transforming
changes in the industry have rendered an overly restrictive interpretation of
the exemption both unnecessary and retrogressive in light of such state
regulation. In this context, the Commission need only read the statute as
Congress intended to grant this Application. n36

- ------------
  n35 Standard Oil, 10 SEC at 1129. See also Electric Bond & Share Co., Holding
Co. Act Release No. 11004 33 SEC 21 (Feb. 6, 1952) [hereinafter "EBASCO"].
Standard Oil, Cities Serv., and EBASCO each involved ownership of multiple
public-utility companies formed prior to the Act which were sprawled across
multiple states, some not subject to even minimal state regulation, and others
which, by their nature, could not be the subject of effective regulation. The
Commission characterized Cities Serv. as a case where the record plainly
indicated "an indulgence in practices explicitly condemned by Congress." Cities
Serv., 8 SEC at 336. The Commission noted that for many years, Cities Services
"controlled a far-flung utility empire" with utility operations in twenty states
and Canada. Cities Serv., 8 SEC at 336-37. Moreover, unlike the present case,
Cities Services sought to maintain direct control over the public-utility
operations of its subsidiary.

  n36 The Senate Report reveals that Congress consciously chose to structure
Section 3 to provide broad classes of exemptions that would be conferred in a
flexible fashion unless the Commission "finds the exemption detrimental to the
public interest or the interest of investors or consumers."  The Senate Report
provides a definitive description of the relationship of the "unless and except"
clause to the specific exemptions available under Section 3(a):

          New section 3(a) has been drafted to exempt these holding
          companies which the committee believes ought not to be
          covered because of the fact, and to the extent, that they
          are either intrastate in character or else not essentially
          holding companies in the utility field. The Commission is
          required to exempt any company which falls into one of the
          described classes, unless and except insofar as it
          determines that exemption is detrimental to the national
          public interest. The exemption when invoked applies to the
          company as a holding company and to every subsidiary of
          the exempted holding company as a subsidiary of such
          company . . . .

          It is the duty of the Commission, as to any company which
          it finds to fall in one of these five categories, to
          exempt such company from any provision or provisions of
          Title I to the extent it deems such exemption not
          detrimental to the public interest or the interest of
          investors or consumers. By thus imposing a mandatory duty
          upon the Commission to exempt companies falling within
          defined categories except where such exemption is
          definitely detrimental to the basic purpose of the
          statute, the Committee has felt free to broaden the
          exemptions beyond what would be justified if the
          exemptions had been made unqualified and self-operative,
          and beyond the power of the Commission to correct when
          abused or used to circumvent the purpose of the title.

Senate Report at 5-6, 24 (emphasis added). The flexibility built into Section 3
exemplifies the Commission's precept that the Act "creates a system of pervasive
and continuing economic regulation that must in some measure at least be
refashioned from time to time to keep pace with changing economic and regulatory
climates." Union Elec., Holding Co. Act Release No. 18368, 45 SEC 489, n.52
(Apr. 10, 1974).

                                       17

Indeed, the intrastate size and scope of the Illinois Power system reflects
decades of effective regulation, not an absence of regulation. The Illinois
Power system is protected by law from abusive affiliate relationships, and
Chevron is seeking neither to obtain nor to maintain any such relationship with
that system.

          It is  especially  relevant  to this  analysis  that  the Act does not
preclude reliance upon other factors, such as those present here, to demonstrate
the "incidental" nature of a company's holding company status. n37 The
Commission has consistently recognized that it must at times refashion the
standards it employs in administering the Act in order to keep pace with the
changing economic and regulatory climate of the public-utility industry. n38 In
this regard, the Commission may articulate alternatives to, or amplify upon, the
functional relationship test in recognition of the ongoing convergence of the
electricity and natural gas industries.

          For example, in a 1983 no-action letter, the Staff indicated that the
Section 3(a)(3) exemption would apply to the acquisition of a majority interest
in an electric power generating station by an engineering and construction
contractor as part of a proposed settlement of litigation against the
contractor. n39 There, ownership of a nuclear power plant could not be said to
be functionally related to the business of an engineering firm, at least not in
the sense of the earlier Commission interpretations of functional relationship.
In a subsequent no-action letter, the Staff indicated that the Section 3(a)(3)
exemption would apply to the acquisition of a propane-air gas pipeline system by
a company that was primarily engaged in the distribution of fuels by truck, the
sale of propane appliances and equipment, and the sale, repair, and leasing of
forklift trucks. n40 In both of these cases, the ownership of the public-utility
company by the exempt holding company was through acquisition and was not a
natural incident of the holding company's existing operations. Further, the
utility operations were completely distinct from the holding company's existing
operations and did not lend any operational or functional efficiencies to the
primary business of the holding company.

- ------------
  n37 In circumstances where the Commission has developed a test for applying a
provision of the Act, such as a "functional relationship" test, the Commission
may approve an application upon either satisfaction of that test or upon a
demonstration that the application falls within the plain meaning of the statute
and is otherwise consistent with the policies of the Act.  Southern
Communications Serv., Holding Co. Release No. 26211 (Dec. 30, 1994) (approving
formation of  telecommunications  subsidiary based upon the plain meaning of the
applicable provision of the Act and, in the alternative,  based upon application
of the "functional relationship" test for approving diversification proposals);
see also The Regulation of Public-Utility Holding Companies, Division of
Investment  Management,  United States Securities and Exchange  Commission (June
1995) at 86-87 [hereinafter the "1995 Staff Report"].  Under this approach,  the
interpretation  of the Act is not  limited by  decisions  rendered  early in its
administration.

The Commission has recognized that a similar relationship satisfied the
requirements of the Section 3(a)(3) exemption in the case where the utility
activity was the distribution of propane through underground pipelines and the
principal business of the enterprise was the distribution of propane in portable
containers, a business that shares no operational relationship to the pipeline
operations of the utility. National Distillers & Chemical Corp., Holding Co. Act

          It is respectfully submitted that the facts and circumstances of the
present case enable the Commission to articulate non-exclusive, definitional
indicia that Chevron is "only incidentally a holding Company," consistent with
the language and intent of the Section 3(a)(3) exemption. In this instance, the
indicia of the functional relationship of Chevron, the Section 3(a)(3) exempt
entity, to Illinois Power, the public-utility company, and its holding company,
New Dynegy, do not consist of typical "up stream" benefits to Chevron. Rather,
the indicia of the functional relationship are "downstream," in that the
functional relationships of Chevron, a worldwide energy company, to Dynegy (and,
post-merger, to New Dynegy), will confer benefits on New Dynegy and indirect
benefits on Illinois Power, while continuing to serve the legitimate business
interests of Chevron. These indicia are:

     (i)   Chevron is a strategic, long-term investor in Dynegy - thus, although
           Chevron will continue to be primarily engaged and interested in one
           or more energy-related businesses other than the business of a
           public-utility holding company (and as such, Chevron has no interest
           in acquiring, managing and operating the public-utility operations of
           Illinova), Chevron's continuing strategic investment in New Dynegy
           enhances the liquidity of the holding company system and supports the
           financial integrity of the Illinova companies;

     (ii)  The interests of Chevron in the exempt public-utility holding company
           (New Dynegy) are not commercially involved with or dependent upon the
           exempt company's public-utility business, and are based instead on
           other strategic interests, specifically the energy-related aspects of
           New Dynegy's business, such as energy marketing;

     (iii) There are synergistic post-merger benefits of the continuing
           strategic investment that flow downstream directly to the energy-
           related group of which the public-utility is a member. For example,
           Chevron's commercial arrangements with Dynegy provide a substantial
           portion of natural gas and natural gas liquids marketed by Dynegy.
           Such arrangements assure New Dynegy's access to an adequate supply of
           and ability to provide natural gas and other fuels for the public-
           utility's power generation business;

     (iv)  The investment was not made and will not be maintained for the
           purpose of enabling the strategic investor (Chevron) to engage in
           non-arm's-length, related-party transactions with the public-utility
           company, or for the purpose of enabling the investor to finance the
           operations of its non-utility operations. However, the strategic
           relationship of Chevron to New Dynegy will contribute positively to
           the financial integrity and independence of New Dynegy, including the
           regulated public-utility subsidiary of New Dynegy; and

     (v)   Chevron will maintain an operational, functional relationship
           consistent with its incidental holding company status because its
           natural gas products will continue to be sold to the energy-related
           business of New Dynegy, and New Dynegy will continue to market gas
           purchased from Chevron and other gas sellers.

                                       19
<PAGE>

          Granting this Application does not open the door to the indiscriminate
acquisition of public-utility holding company systems. Chevron's minority
interest in New Dynegy is distinguishable from the situation where a company
which is not primarily engaged in the energy business and with no functional
relationship to the public-utility holding company, proposes to acquire a
significant interest in a public-utility holding company, with the expectation
of deriving significant return on investment from the utility operation.

          The Commission's broad definitional powers permit it to interpret the
"only incidentally a holding company" requirement in a manner that encompasses
the nature of Chevron's indirect interest in Illinois Power. It is respectfully
submitted that the above articulation of the functional relationship test is
consistent with the purposes of the Act, including the protection of investors,
and satisfies the statutory requirement that Chevron be "only incidentally a
holding company."

C.  CHEVRON WILL NOT DERIVE A MATERIAL PART OF ITS INCOME FROM THE PUBLIC-
    UTILITY COMPANY SUBSIDIARIES OF NEW DYNEGY.

          The other requirement of Section 3(a)(3) - that Chevron will not
derive a material part of its income from the public-utility operations of New
Dynegy (principally those of Illinois Power) - is fully satisfied here. Even
though Illinova's revenues and assets are small in relation to Chevron's, they
are inconsequential when considered on the basis of Chevron's 28% indirect
interest in New Dynegy. Chevron's 28% equity interest in New Dynegy corresponds
to (i) public-utility revenues representing less than 2% of Chevron's revenues,
and (ii) utility operating income representing less than 1% of Chevron's
operating income and less than 1.5% of Chevron's net income.

          Set forth below is a comparison (Chart A) and percentage computation
(Chart B) of the respective total revenues, operating income, net income and
assets of Chevron and Illinova's utility operations, in each case based on the
most recent available data (the fiscal year ending December 31, 1998):

          Immediately following the Transaction, Chevron's equity ownership in
New Dynegy will be 28%. When computed on the basis of an assumed Chevron 28%
ownership interest in New Dynegy, Chevron's status under Section 3(a)(3) is even
more compelling.

Thus, based on attribution to Chevron of an indirect interest of 28% in the
public-utility company operations of Illinois Power following consummation of
the Transaction, Chevron may be deemed to derive only 1.9% of its total
revenues, less than 1% of its operating income, and less than 1.5% of its net
income directly or indirectly from the total utility revenues and utility
operating income of Illinois Power.

D.  ILLINOVA'S PUBLIC-UTILITY COMPANY OPERATIONS SATISFY ANY ABSOLUTE SIZE
    LIMITATION.

          The Commission has also, at times, required that the subsidiary's
public-utility company operations be subject to an absolute size test. As
discussed above, Cities Service involved a mammoth multi-state system with 89
public-utility company subsidiaries controlled by the holding company that
presented all of the evils the Act was intended to address. n43 Similarly, the
Commission's decision in Standard Oil addressed a system with four public-
utility company subsidiaries located in three states, which was at least "the
third largest [gas utility system] in the United States." n44 Given Standard
Oil's size, the Commission stated that, even had there been a functional
relationship between Standard Oil's business and the utilities, it would not
have approved of the exemption. The "small size requirement" has been confined
to cases involving huge systems that evolved without regulation, were not
subject to effective regulation, and were trying to avoid registration even
though their operations were the plain targets of the Act.

          Unlike other Section 3(a)(3) applicants denied the exemption by the
Commission, Illinova's public-utility company operations are confined to one
area, and are not far-flung among

several different regions. n45 Illinova's public-utility company operations are
entirely located in Illinois and are wholly subject to the jurisdiction of a
single public service commission. Illinois Power's size is a function of
regulation, not an indication of the absence of effective regulation.

          The transfer of Illinois Power's generation to Illinova Marketing
(which will become an EWG within one year of the closing of the Transaction) has
had a dramatic effect upon Illinois Power's investment in public-utility assets
and the character of its revenues. Illinois Power's rate base has been reduced
by approximately 50%. Although Illinois Power's customer base is expected to
remain stable, this merely reflects a power delivery service obligation imposed
by regulation. Customers will be free, however, to purchase electric energy from
their supplier of choice.

          In the short term, Illinois Power expects its revenues to decline
somewhat and then to remain relatively stable as a result of the Illinois
statutory rate reductions and rate freezes designed to protect consumers and to
provide an opportunity to recover substantial transition costs. The composition
of such Illinois Power revenues, however, will also change: the revenues
received under the fixed rate structure must recover regulatory transition costs
and purchased power costs constituting approximately 50% of revenues. Illinois
Power's revenues will, therefore, make a reduced contribution to net-earnings,
as shown on its projected pro forma 2000-2004 Income Statement. n46

          Exhibits N and L specifically address the issue of size. The
comparisons on Exhibit N are on an equivalent actual basis using the most recent
available electric and gas utility data, including power generation,
transmission and distribution. n47 Illinova's electric utility revenues
(including bundled generation, transmission and distribution service) are
compared to the other regional electric utilities. In other words, Exhibit N
makes no downward adjustment to Illinova's electric revenue or assets based on
the severing of generation from power delivery or the expected EWG status of the
fossil-fired generation owned by Illinova. n48

   n45 In contrast, in Standard Oil, the applicant's public-utility operations
encompassed substantial portions of three states, and in Cities Serv. the
applicant had a "far-flung" utility empire with eighty-nine public utility
subsidiaries operating in numerous states and Canada.

   n46 See Illinois Power Company pro forma Net Revenues Statement, 1996 to
2002, attached hereto as Exhibit L-2.

   n47 The page enumeration of Exhibit N corresponds to the corresponding pages
of the data presented in Exhibit K to the application under the Act filed by AES
Corporation. See Amendment No. 2 to Application on Form U-1/A under the Public
Utility Holding Company Act of 1935 of AES Corporation (Mar. 5, 1999) (the "AES
Application). The AES Application was approved in AES Corp., Holding Co. Act
Release No. 27063, 70 SEC Docket 972 (Aug. 20, 1999). Applicants are presenting
updated data from the same data source as was presented in the AES Application.

   n48 Exhibit N also makes no adjustment to account for the now completed sale
of the Clinton Facility by Illinois Power to a non-affiliate. The data also does
not reflect the sale of Commonwealth Edison's fossil generation. The purchaser,
Mission Energy, is a large generator of power utilizing exempt generation assets
and is affiliated with a large utility system. Despite the divestiture,
Commonwealth Edison will continue to be a large utility system, significantly
larger than Illinois Power, due to its retention of a large base of nuclear
power generation, its power delivery system and a large customer base.  No
adjustment is made for the two pending mergers involving Northern States Power
(with New Century) and Commonwealth Edison (with PECO).  These

          The region that includes the State of Illinois and bordering states is
the most pertinent for the purpose of the analysis of size. In enacting retail
open access, the State of Illinois relied upon legislative findings that
"[c]ompetitive forces are affecting the market of electricity as a result of
recent federal regulatory and statutory changes and the activities of other
states." n49 The Illinois scheme of retail access harnesses the competition
created by the availability of transmission service on an open access basis to
protect consumers and reward investors. Illinova is interconnected and provides
transmission service to numerous regional utilities that provide transmission
service and compete with Illinois Power, in addition to facilitating the entry
of other competitors. n50

          Exhibit N-6 shows the revenue ranking and share of cumulative revenue
of investor-owned electric utility companies for Illinois and bordering states.
As shown therein, Illinova's electric utility revenue is a small percentage
(4.6%) of the region studied and is lower than the same percentage for three
registered holding companies (American Electric Power: 18.2%, Cinergy: 12.9%,
Ameren: 8.2%) and two exempt holding companies (Unicom: 18.4%, NSP: 6.8%). In
short, 64.4% of the regional electric revenue is received by investor-owned
electric utilities with greater revenues than Illinova. n51

          As Exhibit N-6 demonstrates, Illinois Power's regional asset ranking
is consistent with its revenue ranking. Illinova represents only a small
percentage (6.4%) of regional electric utility assets. Exhibit N-6 also
illustrates that Illinois Power's electric power customer base is small (3.2%).
Moreover, as shown by Exhibit N-7, the same is also true for Illinois Power's
natural gas service revenues (3.9%), assets (4.4%), and customers (3.3%) on a
regional basis.

          Comparing the combined utility operations of Illinova with the
combined utility operations of regional companies does not alter these
conclusions. Exhibit N-9 demonstrates that Illinova's utility revenue (4.5%),
asset (6.1%) and customer (3.2%) shares are small in comparison with those of
other regional companies. On a national basis, too, Illinova is small, as

pending mergers, and the pending American Electric Power Company merger (with
CSW), confirm the evolution of power supply by being dominated by large regional
multi-state systems, as opposed to small single-state utilities such as Illinois
Power.

  n49 220 Ill. Comp. Stat. 5/15-101A(b) (1997 Cum. Supp.).

  n50 Illinois Power has implemented open transmission access in accordance
with FERC Order 888 and has joined a regional Independent System Operator.
Illinois Power maintains substantial transmission interconnections with major
regional electric utilities, including the TVA, American Electric Power, Ameren,
Cinergy, and Commonwealth Edison, all of which are significantly larger than
Illinois Power. Open access transmission also makes regional energy resources
available to all wholesale and retail open access customers connected to the
Illinois Power system. Regional electric competition and open access for
electricity also bring competition to bear on natural gas service. This results
from the substitution of electric energy for gas. Large gas consumers already
have access to competitive supply as a result of FERC Order 636.

  n51 This analysis excludes the Tennessee Valley Authority ("TVA") and other
public power agencies and cooperatives. TVA is larger in all relevant respects
than any of the investor-owned utilities in the Illinova region, and has
exchange power relationships with Illinois Power, American Electric Power,
Ameren, and Cinergy, all of which compete in the Illinova region. TVA was not a
significant source of power during the early years of the administration of the
Act.

                                       24

is shown by Exhibit N-10. For example, Exhibit N-10 shows that Illinova
represents 0.9% of the national revenue of electric companies.

          Of utilities with operations based in Illinois, two utilities, Unicom
and Ameren, are significantly larger than Illinova in terms of revenue rank,
asset size, and number of customers. Those two utilities represent the clear
majority of the revenues, assets and customers of utility operations in
Illinois. Illinova's percentage shares of revenues (13.5%), assets (15.6%), and
customers (10.2%) are significantly smaller than those previously found in
Section 3(a)(3) cases to be "too large."

          As shown by Exhibit L, current and historical financial and operating
data overstate the size of Illinova's public utility operations following
restructuring. Exhibit L is an analysis prepared by Illinova of its natural gas
distribution and electric power delivery (transmission and distribution) public-
utility operations. Exhibit L contains information regarding the public-utility
operations of Illinois Power excluding the power generation to be divested by
Illinois Power. Exhibit L-1 presents adjusted historic and projected pro forma
balance sheet entries. It demonstrates the reduction in the utility plant of
Illinova resulting from restructuring. For example, Illinova's utility plant
(net of depreciation and excluding capitalized nuclear fuel leases) for 1998 was
$4.455 billion. Exhibit L-1 shows that the net utility plant for the natural gas
and power delivery segments of Illinois Power in 1998 would have been $1.643 and
is projected to be $1.586 billion in 2000. The asset base of Illinova's public-
utility operations will be halved by the process of restructuring.

          Exhibit L-2 further shows that the character of Illinova's public-
utility revenues will change and exemplifies how current and historical data
overstate the size of the public-utility operations to be retained by Illinova.
Illinois Power's rates are frozen and must include purchased power costs and
transition cost recovery. In 2000, Illinois Power's estimated purchased power
costs will equal $601 million - approximately half its total revenues - revenues
that include pass-through recovery of purchased gas costs of $195 million.
Illinois Power estimates that it will recover $55 million in transition costs
within its frozen retail electric rates in 2000 and more in subsequent years.
The size of the transmission and distribution business that will remain within
Illinois Power is overstated by these revenues, because the regulatory system
uses those services to recover transition costs, similar to tax collection.
Exhibit L-2 shows that the projected public-utility revenues for Illinova net of
transition charges and purchased power are projected to be approximately $600
million. Turning to Exhibit N-9, regional firms with public-utility revenues in
excess of $600 million are responsible for in excess of 90% of the public-
utility revenues in the region.

          The pervasive regulation and service obligations imposed by Illinois
law upon the delivery function retained by Illinois Power and the rigorous
competition introduced to electric power generation and energy supply by the
FERC and Illinois law have dealt effectively with the concerns over arbitrary
and monopolistic behavior that were raised by the sprawling and ineffectively
regulated systems dealt with in EBASCO, Standard Oil, and Cities Serv.

                                       25
<PAGE>

          Illinois Power's retained public-utility system is small in any
relevant sense today, and, in any event, its size is not a proxy for economic
power or threat to the public interest. n52 To the extent size analysis plays
any legitimate role in considering the availability of an exemption under
Section 3(a)(3), Illinova does not have the type of public-utility company
market share or widespread public-utility company operations that have prompted
the Commission to deny Section 3(a)(3) exemptions in the past. Instead,
Illinova's public-utility company operations are localized, are regulated in a
thorough and comprehensive fashion, and constitute only a small share of a large
and growing regional marketplace. Indeed, the relative size data further suggest
that the notion of an "absolute size test," as a regulatory gloss, may serve no
meaningful regulatory purpose in an era of effective state regulation and
industry-wide consolidation.

          The Commission has both the authority and the duty to continue to
adjust its interpretations (and regulatory tests) under the statutes it
administers to reflect the changing environment of utility operations, structure
and state regulation. It is respectfully submitted that the Commission has ample
tools with which to deal with that environment within the plain meaning of
Section 3(a)(3), and that the size of a utility may, at best, be a secondary
factor in making a determination under the exemption.

E. GRANTING THE EXEMPTION IS CONSISTENT WITH THE PUBLIC INTEREST AND THE
   LEGISLATIVE INTENT THAT THE COMMISSION APPLY SECTION 3 OF THE ACT FLEXIBLY.

          Once the Commission has found that a holding company is only
incidentally a holding company in accordance with Section 3(a)(3), the Act
provides that the Commission shall exempt the holding company from the Act
"unless and except insofar as it finds the exemption detrimental to the public
interest or the interest of investors and consumers." The legislative history of
Section 3 of the Act, and in particular the legislative history of the "unless
and except" clause, demonstrates that Congress expected the Commission to apply
Section 3 of the Act in a flexible fashion in light of contemporary
circumstances. n53 The Commission also has stated that the broad and flexible
language of the "unless and except" clause should be read "in a way that makes

   n52 The Commission has recognized the enhanced jurisdiction, authority and
effectiveness of state commissions.  Statement of the U.S. Securities and
Exchange Commission Concerning Proposals To Repeal The Public Utility Holding
Company Act of 1935 (June 2, 1982) 585, 590-91 [hereinafter "Statement of the
SEC Concerning PUHCA Repeal"].  See also AES Corp., 70 SEC Docket at 55-59 &
n.23.  (recognizing effectiveness of the ICC).  The size and scope of Illinois
Power's operations are the result of years of effective state and federal
regulation and do not represent either private commercial power or the ability
to evade regulation.  Of course, regulation itself can increase the size of a
public-utility company by requiring that service be widely available without
discrimination and at low cost.  For this reason, courts have long held that the
size of effectively regulated public service corporations alone does not
indicate the existence of private market power.  See Cost Management Serv. v.
Washington Natural Gas Co., 99 F.3d 937, 950-51 (4th Cir. 1998); Rebel Oil Co.
v. Atlantic Richfields, 51 F.3d 1421, 1439 (9th Cir. 1995); Southern Pacific

economic and social sense in the light of contemporary realities." n54 In recent
proceedings, the Commission has determined that one of the contemporary
realities to consider in deciding whether an exemption would be contrary to the
public interest is "the protection afforded to investors, consumers, and the
public by the existence of vigorous state regulation." n55

          The Transaction will not result in any reduction in the oversight
exercised by the ICC and FERC. Moreover, all of Illinois Power's public-utility
activities will continue to take place in a single state. Thus, in this
instance, as in prior proceedings where the Commission declined to apply the
"unless and except" clause, the grant of an exemption from the Act would not
result in a regulatory gap and, therefore, would not be detrimental to the
public interest. Rather, the resulting holding company structure will serve the
public interest and the interest of investors and consumers by producing a
number of economies and efficiencies, similar to those upon which the Commission
has in the past looked favorably. n56

          Further, the interest that Chevron will hold in Illinova arises as a
result of dramatic transitions in the industry, including the convergence of
natural gas and electricity. This convergence has been recognized as consistent
with the public interest by the Commission and will not signal the potential for
evasion of the Act. The Illinova public-utility operations will complement and
enhance Dynegy's current exempt utility company operations. The operations which
Dynegy is contributing to New Dynegy will be significant in enabling the company
to provide efficient and competitive utility service, and their value is
enhanced through association with a public-utility company with power generating
assets and experience.

F. GRANTING THE EXEMPTION IS CONSISTENT WITH PROPER INTERPRETATION AND
   ADMINISTRATION OF THE ACT UNDER SECTION 1(C).

          Section 1(c) of the Act requires the Commission to interpret and
administer the Act in order to eliminate the five evils enumerated in Section
1(b)(1)-(5) of the Act. n57 As demonstrated below, the Transaction threatens
none of these evils.

          With respect to the first concern of the Act, the absence of accurate
investor information and the problem of "overcapitalization" of public-utility
systems without sufficient

  n55 WPL Holdings, Inc., Holding Co. Act Release No. 24590 (Feb. 26, 1988).

  n56 See, e.g., Illinova Corp., Holding Co. Act Release No. 26054 (May 18,
1994) (granting exemption requested in connection with a proposed merger based
on an application that claimed that the new structure would create efficiencies
and economies such as allowing the resulting companies to respond to competitive
opportunities in the electric power industry and increasing the financial
flexibility of the resulting companies).

  n57 These evils are: (1) the absence of specific investor information and the
issuance of "overcapitalized" public-utility securities without sufficient state
regulation; (2) abusive and excessive consumer charges to fund affiliate
transactions; (3) the obstruction of state regulation of public-utilities and
their subsidiaries and the exercise of control over subsidiaries through
disproportionately small investment; (4) holding company growth out of
proportion with management and operation, or integration and coordination of
related operating properties; and (5) the lack of economy of management,
efficiency or adequacy of services in the public-utility industry, or the lack
of effective public regulation thereof.

                                       27
<PAGE>

state regulation, the Commission has found that concerns "with respect to
investors have been largely addressed by developments in the federal securities
laws and in the securities markets themselves. . . ." n58

          The State of Illinois, through the ICC, closely regulates the
capitalization of public-utilities n59 and has the express authority to restrict
dividend payments if the public-utility's capital is or would become impaired or
if its earned surplus is insufficient. n60 Furthermore, the securities of
Illinova, Dynegy, and Chevron, as well as the bonds and preferred stock of
Illinois Power are all publicly traded. Accordingly, the Transaction presents
none of the problems, risks, or evils identified by Section 1(b)(1) of the Act.

          Second, the structure poses no risk of abusive affiliate transactions.
The State of Illinois has comprehensive oversight of affiliate transactions such
as those that could occur between Chevron and Illinois Power. n61 The Commission
has recognized that a "comprehensive state system," such as that in effect in
Illinois, n62 "is fully able to protect the financial integrity of the public
utility operating within its jurisdiction to assure that neither utility
revenues (other than reasonable and proper dividends), utility assets, or
utility credit are used for non-utility purposes except in accordance with
prescribed guidelines or following review and approval by state regulators. The
states also appear to have adequate authority to regulate transactions between
the utility and its affiliates to prevent the type of overreaching that
characterized so many holding company systems prior to 1935." n63 In addition,
FERC regulations associated with market-based wholesale rate transactions will
operate to further guard against affiliate abuse following the Transaction. n64
Thus, there is no risk of abusive affiliate transactions between the involved
entities following the Transaction.

          Third, the structure of the Transaction poses no risk of obstruction
of effective state regulation of public-utility company subsidiaries or of the
exertion of control over such subsidiaries through disproportionately small
investment. The State of Illinois has a

  n63 Statement of the SEC Concerning PUHCA Repeal at 590-91. In reaching its
conclusion that state regulation was adequate to the task of preventing
affiliate abuse, the Commission specifically referenced Natural Gas Pipeline Co.
v. Slattery, 302 U.S. 300 (1937), affirming the Illinois regulatory system's
oversight over affiliate transactions. See Statement of SEC Regarding PUHCA
Repeal at 585.

  n64 FERC has erected comprehensive protections against cross-subsidies by
requiring adherence to a "code of conduct" governing transactions between the
franchise-owning public utility and its unregulated marketing affiliates.  These
code of conduct requirements apply to Illinois Power and its affiliates.  See
Illinova Power Marketing, 79 FERC (P) 61,010 (Feb. 1997) and cases cited
therein.

                                       28
<PAGE>

comprehensive regulatory apparatus in place that is not affected by the
Transaction. n65 And here, Chevron's minority voting stock interest in New
Dynegy is proportional to its equity investment in New Dynegy.

          Fourth, the structure poses no risk of holding company growth that
"bears no relation to economy of management and operation or the integration and
coordination of related operating properties." The properties of Illinova's
public-utility operating companies are not affected by the Transaction.

          Finally, Section 1(b)(5) of the Act addresses the situation where "in
any other respect there is a lack of economy of management and operation of
public-utility companies or lack of efficiency and adequacy of service rendered
by such companies, or lack of effective regulation, or lack of economies of
raising capital." The Transaction enables Illinova to obtain the capital assets
needed to conduct an efficient energy marketing business essential to modern
utility service and does not threaten any adverse effects with respect to
public-utility operations.

ITEM 4. REGULATORY APPROVAL

          The Transaction has been reviewed and approved by the FERC under the
Federal Power Act ("FPA"). On July 23, 1999, Dynegy and Illinova filed a joint
application with the FERC requesting that it approve the Transaction under
Section 203 of the FPA. Under Section 203, FERC approves mergers if it finds
that they are "consistent with the public interest." In reviewing a merger, the
FERC evaluates whether the merger will (i) adversely affect competition; (ii)
adversely affect rates to captive wholesale customers; or (iii) impair the
effectiveness of regulation. The FERC found the merger would have none of these
effects and approved the Transaction on November 10, 1999. n66 Following the
Transaction, the FERC will have continuing jurisdiction over New Dynegy's power
marketing business and over Illinois Power and Illinova Marketing with respect
to, inter alia, rates, terms, and conditions for wholesale sales and
transmission transactions (including those with affiliates), and continuing
jurisdiction over the disposition and consolidation of utility assets and
interlocking directorates.

          Illinois Power is currently subject to the jurisdiction of the ICC.
Illinois Power filed notice of the Transaction as it affects Illinois Power's
electric system on August 13, 1999 with the ICC, along with a voluntary
application with the ICC for approval of the Transaction with respect to the
change of control over Illinois Power's gas utility. The required approval was
obtained on November 23, 1999. n67 Following the Transaction, the ICC will
retain its applicable authority over the retail rates, services provided by, and
dividends of the public-utility subsidiaries of Illinova, and their transactions
with affiliates.

- ------------
  n3 By an order dated December 26, 1995, the Commission granted Illinois Power
authorization to transact wholesale sales of electric energy at market-based
rates. See Illinois Power Co., 73 FERC P61,371 (1995).

  n4 On June 29, 1999, in Docket No. EC99-90-000, Illinois Power, Illinova Power

authorization pursuant to Section 203 of the FPA for Illinois Power to divest
all of its fossil-fired generation assets by transferring those assets to
Illinova Marketing, a newly-formed subsidiary of Illinova that will generate and
market electric energy at wholesale. Applicants state that at the outset,
Illinova Marketing's primary responsibility will be to continue to meet the
electric supply needs of Illinois Power's customers through a proposed long-term
purchase power agreement (PPA). Illinova Marketing filed the PPA in Docket No.
ER99-3208-000. The Commission subsequently approved the proposed divestiture and
accepted the PPA by letter orders dated September 10, 1999, and August 24, 1999,
respectively. See Illinois Power Co., 88 FERC P62,229 (1999); Illinova Power
Marketing, Inc., 88 FERC P61,129 (1999).

authorization to transact wholesale sales of electric energy at market-based
rates. See Illinois Power Co., 71 FERC P61,172 (1995).

  n7 By an unpublished Letter Order dated April 7, 1994, in Docket No. ER94-968-
000, the Commission granted Electric Clearinghouse authorization to transact
wholesale sales of electric energy at market-based rates. On June 21, 1999, in
Docket No. ER99-3322-000, Electric Clearinghouse and Illinois Power jointly
filed amendments to their respective market-based rate tariffs for the purpose
of allowing them to sell energy and power to one another as affiliates, as well
as a proposed Code of Conduct in order to account for their post-merger
affiliate relationship. The Commission accepted the filing in Docket No. ER99-
3322-000 by an unpublished Letter Order dated September 10, 1999.

  n8 By an unpublished Letter Order dated January 20, 1995, in Docket No. ER94-
1612-000, the Commission granted Dynegy Power authorization to transact
wholesale sales of electric energy and power at market-based rates. Applicants
indicate that Dynegy Power is engaged almost exclusively in power marketing
activities in Texas and California, and neither sells nor markets power to
Illinois Power or its affiliates. Applicants also state that Dynegy Power
commits not to engage in any power marketing transactions with the Illinova
parties. Application at 9, n.15.

<PAGE>

  Furthermore, Dynegy, through intermediate subsidiaries, indirectly owns
interests in 24 generating facilities (totaling 5,732 MW) of which all are

throughout North America (primarily in Texas and California) and interests in
six generating facilities (totaling 2,684 MW) to be constructed in Arizona,
Louisiana, Georgia, Kentucky and North Carolina. n9 Applicants state that in
several instances, Dynegy's combined ownership interest with other public
utility owners in certain qualifying QFs may exceed 50 percent.
Applicants also state that prior to closing of the Proposed Merger, Dynegy will
take such action with regard to these QFs as is necessary to continue to comply
with the requirements of the Commission's regulations implementing the Public
Utility Regulatory Policies Act of 1978 or the Energy Policy Act of 1992.

  b. Natural Gas, NGLs, and Crude Oil Assets

  Dynegy owns either direct or indirect interests in the following: (1) natural
gas gathering and processing facilities located in Kansas, Oklahoma, Texas,
Louisiana, Arkansas, Wyoming and offshore Louisiana in the Gulf of Mexico, as
well as the province of Alberta, Canada; n10 (2) intrastate natural gas

Texas and Louisiana; (10) NGL storage and terminal facilities located in
Louisiana, Texas, Mississippi, Kentucky, and Florida; and (11) lessee rights to
a coal gasification plant located in Indiana.

  B. Description of the Proposed Merger

  The Proposed Merger will be implemented in accordance with an Agreement and
Plan of Merger dated June 14, 1999 (Plan of Merger). n11 The Proposed Merger
will take place through a series of transactions culminating with Newco's
acquisition of the entire equity interest in Illinova and Dynegy and their
respective public utility subsidiaries. In connection with the Proposed
Merger, Illinova has created Newco as an Illinois corporation. Newco, in turn,
has formed two wholly-owned subsidiaries, Energy Convergence Acquisition Company
(Energy Acquisition), an Illinois corporation, and Dynegy Acquisition Company
(Dynegy Acquisition), a Delaware corporation.

  The Proposed Merger will be accomplished by two concurrent mergers. In the
first merger, Energy Acquisition will be merged with and into Illinova, with
Illinova as the surviving corporation (Illinova Merger). Each outstanding share
of Illinova common stock will be converted into one share of Newco Class A
common stock. Concurrent, with the

- ------------
  n9 Application at Attachment 2.

  n10 According to the application, Dynegy's processing facilities are not
subject to the Commission's jurisdiction under the NGA.

  n11 Application at Exhibit H.



<PAGE>

Illinova Merger, Dynegy Acquisition will be merged with and into Dynegy, with
Dynegy as the surviving corporation (Dynegy Merger). As noted below, with the
exception of BG Holdings, Chevron, and NOVA, each outstanding share of Dynegy
common stock will be converted into either $16.50 in cash (subject to a cap on
the total cash that may be received in the aggregate by Dynegy
shareholders) or 0.69 shares of Newco Class A common stock (with fractional
shares to be cashed out). At the effective time of the Proposed Merger, Energy
Acquisition and Dynegy Acquisition will cease to exist as corporate entities.

  Upon consummation of the Proposed Merger, Newco will continue its existence as
a corporation under Illinois Law n12 and will directly own all of the issued and
outstanding capital stock of Illinova and directly and indirectly own all of the
issued and outstanding capital stock of Dynegy. Accordingly, Illinova and Dynegy
will be wholly-owned subsidiaries of Newco. Illinova and Dynegy will continue to
own all of their pre-merger assets and be liable for all of their respective
liabilities. Illinova's debt and Dynegy's debt will remain the obligation of
Illinova and Dynegy, respectively.

  Newco and British Gas Atlantic Holdings BV (BG Atlantic), a Netherlands
corporation and direct corporate parent of BG Holdings, have entered
into a Stock Purchase Agreement (BG Stock Purchase Agreement) pursuant to which
Newco will purchase 100 percent of the issued and outstanding shares of BG
Holdings from BG Atlantic in exchange for a combination of cash and Series A
Convertible Preferred Stock (Preferred Stock). Under the BG Stock Purchase
Agreement, BG Atlantic will receive the same amount in a combination of cash and
Preferred Stock in consideration for the capital stock of BG Holdings as BG
Holdings would have received in the Proposed Merger by virtue of its ownership
shares of Dynegy common stock. Upon the consummation of the Proposed Merger, and
depending on actual stockholder elections, BG Atlantic will own a 3.5 percent to
5 percent equity interest in Newco.

  Newco and Chevron have entered into a Subscription Agreement pursuant to which
Chevron will purchase a minimum of $200 million and a maximum of $240 million of
Newco Class B common stock (Class B Shares) concurrent with the closing of the
Proposed Merger (Equity Investment). Additionally, pursuant to the Plan of
Merger, Chevron will receive Newco Class B Shares in the Dynegy Merger (rather
than Class A common stock) in exchange for Chevron's equity interest in
Dynegy common and preferred stock. By virtue of its acquisition of Class B
Shares in the Proposed Merger and the Equity Investment, Chevron will own a 28
percent to 29 percent equity interest in Newco. n13

  Pursuant to the terms of the Plan of Merger, NOVA will receive in the Dynegy
Merger a combination of cash and Preferred Stock in exchange for its entire
equity interest in Dynegy common stock. Upon consummation of the Proposed
Merger, and depending on actual stockholder elections, NOVA will own a 3.5
percent to 5 percent equity interest in Newco.

  The remainder of Newco Class A common stock will be owned, in part, by Newco
management, and the remaining shares not owned by Newco management will be
publicly traded on the NYSE.

- ------------
  n12 According to the application, Newco will be renamed Dynegy Inc. upon
consummation of the Proposed Merger.

  n13 According to the application, Chevron will have certain minority
shareholder protection rights with respect to Newco, including the right to
appoint three members to the Newco Board of Directors.

III. Notice of Filing and Interventions

  Notice of the Applicants' filing was published in the Federal Register, n14
with motions to intervene and protests due on or before September 21, 1999. The
Illinois Municipal Electric Agency filed a timely motion to intervene in support
of the merger. MidAmerican Energy Company, Natural Gas Pipeline Company of
America, and Chevron U.S.A., Inc. each filed a timely motion to intervene
raising no substantive issues.


IV. Discussion

  A. Procedural Matters

  Pursuant to Rule 214 of the Commission's Rules of Practice and Procedure, 18
C.F.R. (S) 385.214 (1999), the timely, unopposed motions to intervene of the
Illinois Municipal Electric Agency, MidAmerican Energy Company, Natural Gas
Pipeline Company of America, and Chevron U.S.A., Inc. serve to make them parties
to this proceeding.

  B. Standard of Review

  Section 203(a) of the FPA provides, in relevant part, as follows:

        No public utility shall sell, lease, or otherwise dispose of the whole
        of its facilities subject to the jurisdiction of the Commission, or any
        part thereof of a value in excess of $50,000, or by any means
        whatsoever, directly or indirectly, merge or consolidate such facilities
        or any part thereof with those of any other person, or purchase,
        acquire, or take any security of any other public utility, without first
        having secured an order of the Commission authorizing it to do so.

16 U.S.C. (S) 824b(a) (1994). Under Section 203(a), the Commission must approve
a proposed merger if it finds that the merger "will be consistent with the
public interest." Id.

  In 1996, the Commission issued its Merger Policy Statement updating and
clarifying its procedures, criteria and policies applicable to public utility
mergers. n15 The Merger Policy Statement provides that the Commission will
generally take account of three factors in analyzing proposed mergers: (a) the
effect on competition; (b) the effect on rates; and (c) the effect on
regulation.

  For the reasons discussed below, we find that Applicants' proposed merger, as
conditioned below, is consistent with the public interest. Accordingly, we will
approve the merger without further investigation.

  C. Effect on Competition

  1. Applicants' Analysis

  Applicants evaluate the horizontal and vertical competitive implications of
the Proposed Merger. In regard to horizontal effects, Applicants identify non-
firm energy and short-term capacity as the relevant product and use, among

other measures, economic capacity as a proxy for a suppliers' ability to
participate in the relevant product market. In their analysis of economic
capacity, Applicants identify and define seven relevant geographic
("destination") markets using the approach described by Appendix A of the Merger
Policy Statement. n16 Applicants' results show that pre- to post-merger
increases in concentration in several highly concentrated relevant markets are
negligible (e.g., 1,836 to 5,352 HHI with increases of 6 HHI or less). The
results are higher in the moderately concentrated post-merger Illinois Power
market (1,154 to 1,558 HHI with increases less than 45) and the highly
concentrated LG&E markets (2,108 to 2,503 HHI with increases less than
23). n17 However, in no relevant market do pre- to post-merger increases in
concentration exceed acceptable thresholds. Applicants conclude from their
analysis that the Proposed Merger raises no market power concerns related to the
horizontal aspects of consolidating generation.

  Applicants maintain that there are no vertical competitive concerns as to
whether the merged company could use gas transportation facilities they own
and/or control to raise their generation rivals' costs or to create
entry barriers. Applicants explain that Dynegy holds some firm transportation
rights on pipelines into the Midwest and its subsidiary Kansas Gas Supply
serves, on an interruptible basis, two of Western Resources' generation plants
(totaling 821 MW). n18 According to Applicants, these two plants are
geographically remote (i.e., two wheels away) from the Illinois Power market and
the full needs of the plants are met from an interstate pipeline connected to
Western Resources. Therefore, Applicants state that "Western Resources
generation is not competitively significant in the areas where Illinois Power
generation is competitively significant." n19 Moreover, Applicants state that
the upstream delivered gas market is "workably competitive" because there are a
large number of interstate long-haul pipelines serving the Midwest markets and
that potential entrants can locate new power plants that could be served by any
of the region's pipelines. n20

  Stating that they have de minimis generation capacity in the downstream
electricity market, the Applicants perform an abbreviated downstream market
analysis to evaluate the vertical aspects of the Proposed Merger. Based on this
limited analysis, Applicants conclude that the Proposed Merger raises no
competitive concerns resulting from the vertical aspects of the consolidation.

  2. Discussion

  We find that the Proposed Merger poses no competitive concerns arising from
the horizontal or vertical aspects of the consolidation. No intervenor protests
or argues otherwise. We note that, as indicated by Applicants' analysis, the

- ------------
  n16 The seven markets are American Electric Power, CINergy, Commonwealth
Edison, Duke Power, Illinois Power, Louisville Gas & Electric and the Tennessee
Valley Authority.

  n17 Applicants evaluate pre- to post-merger increases in market concentration
under a number of different time periods and market prices. The time periods are
summer peak, off-peak and super peak; winter peak and off-peak; and shoulder
peak and off-peak. Market prices (taken from Power Markets Week) range from $28
in summer off-peak to $60 in summer super-peak.

<PAGE>

combination of Illinova's and Dynegy's ownership and/or control of generation
does not increase concentration in the reasonably defined relevant markets so as
to raise significant horizontal competitive concerns.

  In regard to vertical competitive issues, for a merger to adversely affect
competition in downstream electricity markets, the merged firm must have the
incentive and ability to affect prices or output in upstream delivered
gas and downstream electricity markets (e.g., by raising rivals' costs) and
those markets must be conducive to the exercise of market power. n21 We note
that in this particular case, the data contained in the application indicates
two considerations that ameliorate any competitive concern. First, there is
insufficient "overlap" between relevant upstream delivered gas and downstream
electricity markets (i.e., in which gas transportation facilities owned or
controlled by the merged company serve competing generators) to raise
significant competitive concerns. Second, the Proposed Merger does not enhance
the merged company's incentive (i.e., it would not be profitable) to raise its
rivals' costs because it has a relatively small share of the relevant downstream
electricity markets. Given the particular facts and circumstances presented
here, therefore, the Commission believes that the Proposed Merger raises no
significant vertical competitive concerns.

  D. Effect of the Merger on Rates

  The Merger Policy Statement explains our concern that there be adequate
ratepayer protection from adverse rate effects as a result of a merger. It
describes various commitments that may be acceptable means of protecting
ratepayers, such as hold harmless provisions, open seasons for wholesale
customers, rate freezes, and rate reductions. n22

  According to the application, the Proposed Merger will have no adverse effect
on rates. With respect to wholesale generation rates, Applicants state that all
wholesale sales service provided by Dynegy's public utility subsidiaries and all
wholesale sales service provided by Illinova's public utility subsidiaries
(other than those specifically addressed below) consist of sales at negotiated
rates made pursuant to Commission-approved market-based rate tariffs. Applicants
also state that any rates for wholesale sales made through affiliates that own
qualifying facilities will not be adversely affected by the Proposed Merger
because Applicants have no ability to amend the rate terms of the governing
contracts.

  Furthermore, Applicants assert that there will be no adverse impacts from the
Proposed Merger on Illinois Power's wholesale customers. In support, Applicants
indicate that Illinois Power currently does not provide traditional requirements
service to any wholesale customer and it has no active wholesale rate schedules
that contain wholesale fuel adjustment clauses. Applicants also indicate that
Illinois Power provides non-market-based wholesale sales services to only two
wholesale customers, n23 both of which Applicants commit that Illinois Power
will hold harmless by agreeing not to pass merger-related costs through the
respective agreements. n24

<PAGE>


  Finally, with respect to wholesale transmission rates, Applicants note that
Dynegy does not own any transmission facilities other than those incident to its
generation facilities and thus does not provide wholesale transmission service.
Applicants also note that Illinois Power's transmission rates will be subject to
review by the Commission since Illinois Power is a participant in the Midwest
Independent Transmission System Operator (Midwest ISO) and since the Commission
has, among other things, accepted the Midwest ISO's system-wide transmission
tariff for filing and set certain features of that tariff for hearing. n25 In
any event, Applicants commit that Illinois Power will hold its wholesale
transmission customers harmless from any adverse rate effects resulting from the
Proposed Merger and will not seek to pass through any merger-related costs in
its jurisdictional transmission rates for a period of five years commencing on
the closing date of the Proposed Merger. n26

  Intervenors raise no rate or ratepayer protection issues.

  Upon consideration of the above, we conclude that the Proposed Merger will not
adversely affect rates.

  E. Effect on Regulation

  As explained in the Merger Policy Statement, the Commission's primary concern
with the effect on regulation of a proposed merger involves possible changes in
the Commission's jurisdiction when a registered holding company is formed, thus
invoking the jurisdiction of the Securities and Exchange Commission (SEC). We
are also concerned with the effect on state regulation where a state does not
have authority to act on a merger and the state raises concerns about the effect
of the merger on regulation. n27

  According to the application, the Proposed Merger will have no adverse effect
on regulation. With respect to Federal regulation, Applicants contend that upon
consummation of the Proposed Merger, Illinois Power will continue to be
subject to Commission jurisdiction under the FPA and that the Proposed Merger
will not result in the creation of a registered holding company. n28 With
respect to state regulation, Applicants observe that upon consummation of the
Proposed Merger, Illinois Power will continue to be subject to the jurisdiction
of the Illinois Commission with respect to the retail rates charged by Illinois
Power either as a provider of electricity, as a provider of electric delivery
services for unbundled retail electricity sales, and/or as a provider of natural
gas sales and distribution service.

  No intervenor raises any concerns regarding Federal or state regulation.

  Upon consideration of the above, we conclude that the Proposed Merger will not
adversely affect regulation.

  F. Accounting Issues

  Applicants state that the Proposed Merger will take place at the holding
company level, with no effect on account balances and financial statements of
the jurisdictional utility, Illinois Power. For this reason, Applicants request
a waiver of the requirement to file their accounting for the merger. Based on
Applicants' assertion that Illinois Power's account balances and financial
statements will not be affected by the merger and the understanding that
Illinois Power will continue to maintain its accounts in accordance with the
Commission's Uniform System of Accounts, we will grant the waiver of the
requirement to file accounting related to the merger.

The Commission orders:

  (A) Applicants' proposed merger is hereby approved subject to the commitments
discussed in the body of this order.

  (B) The request for waiver of the requirement to file accounting related to
the merger is hereby granted.

  (C) The foregoing authorization is without prejudice to the authority of the
Commission or any other regulatory body with respect to rates,
services, accounts, valuation, estimates or determinations of cost, or any other
matter whatsoever now pending or which may come before the Commission.

  (D) Nothing in this order shall be construed to imply acquiescence in any
estimate or determination of cost or any valuation of property claimed or
asserted.

  (E) The Commission retains authority under section 203(b) of the FPA to issue
supplemental orders as appropriate.

  (F) Applicants shall notify the Commission that the merger has occurred within
10 days of the date the merger is consummated.

as a public utility holding company under section 3(a)(1) of PUHCA. Applicants
also state that at a point in time subsequent to the Proposed Merger, Illinova's
corporate existence will be extinguished and Illinois Power will become a
direct, wholly-owned subsidiary of Newco.

                                     ORDER

By the Commission:

I.  PROCEDURAL HISTORY

     On August 13, 1999, Illinois Power Company ("IP" or "Company") filed an
application with the Illinois Commerce Commission ("Commission"), pursuant to
Section 7-204 of the Public Utilities Act ("Act") (220 ILCS 5/7-204), seeking an
expedited order approving a reorganization with respect to IP's gas utility
business, and an order pursuant to Section 7-101 of the Act (220 ILCS 5/7-101)
for approval of an Interim Service and Facilities Agreement between IP and its
affiliated interests, and for other related relief.  The reorganization results
from a transaction by which Dynegy, Inc. ("Dynegy") will acquire control of
Illinova Corporation ("Illinova"), the parent of IP.  IP is a combination gas
and electric utility providing retail gas and electric service to customers in
Illinois.

     Local Union No. 51, International Brotherhood of Electrical Workers,
AFL-CIO ("Local No. 51, IBEW") filed a petition to intervene.  That petition was
granted by the Hearing Examiner.  Local Union No. 51, IBEW, however, did not
participate in this proceeding.  No other petitions to intervene were received.

     Pursuant to proper legal notice, status hearings were held in this matter
on September 3 and 30, 1999, and an evidentiary hearing was held on October 18,
1999, at the Commission's offices in Springfield, Illinois.  Appearances were
entered by counsel on behalf of IP and Commission Staff.  At the hearing on
October 18, 1999, IP submitted the testimony of Larry F. Altenbaumer, IP's
Senior Vice President and Chief Financial Officer; John U. Clarke, Dynegy's
Senior Vice President and Chief Financial Officer; Robert A. Schultz, IP's Vice
President - Finance; and Cynthia G. Steward, IP's Controller.   Mr. Thomas Q.
Smith, an Accounting Supervisor in the Accounting Department of the Financial
Analysis Division of the Commission, submitted testimony on behalf of Staff.  At
the conclusion of the hearing on October 18, 1999, the record was marked "Heard
and Taken."  IP and Staff waived the filing of initial and reply briefs and the
service of a Hearing Examiner's proposed order.

II.  DESCRIPTION OF THE PROPOSED REORGANIZATION

     IP's Petition states that on June 14, 1999, Illinova entered into a Plan of
Merger with Energy Convergence Holding Company, Energy Convergence Acquisition
Company, Dynegy Acquisition Company, and Dynegy Inc.  The proposed merger will
involve the merger of Energy Convergence Acquisition Company, an Illinois
corporation, all of whose common stock is owned by Energy Convergence Holding
Company, an Illinois corporation, with and into Illinova, with the result that
all of the common stock of Illinova will be owned by Energy Convergence Holding
Company.  Concurrent with this transaction, Dynegy Acquisition Company, a
Delaware corporation, all of whose common stock is owned by Energy Convergence
Holding Company, will be merged with and into Dynegy Inc., a Delaware
corporation, with the result that all of the common stock of Dynegy Inc. will be
owned by Energy Convergence Holding Company.  As a result of these mergers,
Illinova and Dynegy will continue to exist, but rather than being independent,
publicly traded companies will instead be subsidiaries of Energy Convergence
Holding Company.  Further, Energy Convergence Holding Company will be renamed
Dynegy Inc., and the current Dynegy will be renamed.  Following this
reorganization, a second reorganization is contemplated in which Illinova is
merged into Energy Convergence Holding Company.  After the second
reorganization, Illinova will cease to exist, and the new Dynegy will become the
owner of all of the common stock of IP.  It is not certain at this time when
that second reorganization will occur.  These transactions are referred to
throughout this Order as the "Reorganization" or the "Merger."  The Merger is
expected to close no earlier than December 31, 1999, and no later than the end
of the first quarter 2000.

     Dynegy's Senior Vice President and Chief Financial Officer, Mr. Clarke,
testified that although Illinova and Dynegy view this transaction as a merger of
equals, the Merger will be accounted for as a purchase of Illinova by Dynegy.
The board of directors of the new holding company will be comprised equally of
seven members from Illinova's current board and seven members from Dynegy's
current board.  Chuck Watson, Dynegy's current Chief Executive Officer, will be
the Chairman of the Board and Charles Bayless, Illinova's current Chairman,
President, and Chief Executive Officer, will be a non-executive member of the
Board.  Mr. Altenbaumer will serve as President of IP and will be directly
involved in the strategic management of IP after the Merger.

     Mr. Altenbaumer explained that the new company will consist of eight
functional operation divisions, including Marketing, Trading, Generation
Operations, Midstream Services, Dynegy Energy Services, Commercial Power, IP,
and U.K./Europe.  He explained the reasons for the proposed Merger.  He stated
that the proposed Merger is the next step in the evolution of Illinova into a
multi-regional, diversified energy services company.  The Board of Directors and
Senior Management of Illinova and IP concluded that the Illinova family of
companies needed to enlarge its financial and skill base in order to remain a
viable competitor in the energy markets.  He stated that

                                       2
<PAGE>

                                                                         99-0419

Dynegy has a strong management team that will provide IP knowledge and expertise
it does not now have. In addition, the increased size provided by the Merger
brings financial strength and scale to Illinova and IP. He testified that the
Merger will provide Illinova access to the extensive experience of Dynegy in the
energy markets in the United States and around the world, and thus will bring
added national and international connections to the Illinois economy in the U.S.
and global markets. IP believes that the combination of these two companies will
create a balanced and strong company that will enhance IP's ability to provide
service to both large and small natural gas customers. Mr. Altenbaumer concluded
that the Merger will maximize the value of both Illinova's and Dynegy's assets
and strengths while at the same time maintaining and enhancing IP's ability to
meet its regulated service obligations.

     Mr. Clarke described the reasons for the proposed Merger from Dynegy's
perspective.  A primary reason for Dynegy entering into the Merger was its
desire to obtain a presence in the Midwest power market.  Illinova has
strategically positioned generating facilities as well as a developing national
energy services business.  In addition, both companies are leading independent
power developers and producers.  IP's retail distribution expertise, coupled
with Dynegy's natural gas marketing expertise, provides a broad spectrum of
value opportunities.  He testified that the combined company will be a national
leader in the rapidly changing energy industry and will be well positioned to
capitalize on opportunities created by energy convergence.  Mr. Clarke stated
that the combination of Illinova and Dynegy will result in a highly diversified
but strategically focused energy company.  The combined company will have the
scale, scope, and skills to compete effectively in the emerging national energy
marketplace and will benefit from advantages not available to either of the
Merger partners on a stand-alone basis.  He stated that both of the merging
companies believe the Merger will result in greater value to their customers and
shareholders while creating the size and scale necessary to be successful in a
restructured energy market.

III.  DESCRIPTION OF DYNEGY

     Mr. Altenbaumer testified that Dynegy is a major North American marketer of
natural gas, natural gas liquids, crude oil, coal, electricity, liquid petroleum
gas, and related services.  It also engages in natural gas gathering, processing
and transportation, and electric power generation.  Its corporate headquarters
is located in Houston, Texas.  In 1998, Dynegy was ranked fourth nationally for
wholesale power marketing and trading, based on volume.  It was ranked fifth for
gas marketing during the same period.  Mr. Altenbaumer stated that Dynegy does
not own any incumbent local gas distribution facilities.  However, Dynegy or its
affiliates sells natural gas in the unregulated retail markets throughout the
country, including in Illinois.  With regard to Illinois, Dynegy Marketing and
Trade and NICOR Energy L.L.C., in which Dynegy owns a 50% interest, both sell
gas at retail in Illinois to end use customers.  Sales to end use customers in
IP's retail gas service territory by these companies account for less than 2% of
the throughput on IP's system.

                                                                         99-0419

     Mr. Clarke described Dynegy's Marketing and Trade business unit.  Dynegy
owns a direct 100-percent interest in Dynegy Marketing and Trade, Electric
Clearinghouse, Inc. ("ECI") and Dynegy Power Services, Inc. ("Dynegy Power").
Dynegy Marketing is engaged in the marketing and trading of natural gas, coal,
natural gas liquids, crude oil, and liquid petroleum gas.  As part of its
operations, Dynegy Marketing controls the domestic marketing of natural gas for
certain subsidiaries of Chevron Corporation.  ECI is engaged in the marketing of
electric energy and power and other energy commodities at wholesale and retail
throughout North America.  Dynegy Power is engaged in the brokering and
marketing of electric energy, natural gas, and other energy commodities at
wholesale and retail throughout North America.  In addition to its ownership
interests in the energy marketers described above, Dynegy, through intermediate
subsidiaries, indirectly owns interests in several generating facilities located
throughout North America.

     Mr. Clarke also described Dynegy's natural gas liquids business.  Operating
primarily through Dynegy Mid-Stream Services, L.P., a wholly-owned subsidiary,
Dynegy engages in the gathering and processing of natural gas and the
transportation, fractionalization, and storage of natural gas liquids.  Mr.
Clarke testified that Dynegy also markets natural gas, natural gas liquids, and
crude oil through its affiliated marketers, including Dynegy Marketing and
Trade.  Dynegy also has ownership interests in and operates natural gas
processing facilities located in the states of Oklahoma, Utah, Texas, Louisiana,
New Mexico, and Arkansas.  Dynegy also owns and operates two natural gas
processing facilities located in Alberta, Canada.  These facilities are used to
refine raw natural gas into marketable pipeline quality natural gas by
extracting various natural gas liquids, and consist of both field plants, which
aggregate volumes from multiple producing wells, and straddle plants, which are
situated on mainline natural gas pipelines.  Dynegy also owns and operates
various gathering systems and interstate and intrastate pipelines that transport
natural gas, crude oil, and liquids.  Through subsidiaries, Dynegy owns
interests in three natural gas fractionalization facilities located in the
states of Texas and Louisiana.  These facilities are used to separate the
commingled stream of liquid hydrocarbons removed from the natural gas stream at
natural gas processing plants into marketable component products.  Incident to
its natural gas liquids transportation operations, Dynegy also has ownership
interests in and operates product storage and terminal facilities located in the
states of Louisiana, Texas, Mississippi, Kentucky, and Florida.

     Mr. Clarke testified that Dynegy's issued and outstanding common stock is
principally owned by three entities: British Gas plc ("BG"), Chevron Corporation
("Chevron") and NOVA Chemicals Corp. ("NOVA"), which each own approximately 26%
of the issued and outstanding common stock of Dynegy.  Ten percent of the common
stock of Dynegy is held by senior management, and the remaining shares are
publicly traded.  After the Merger, it is expected that the issued and
outstanding common stock of the new Dynegy will be owned as follows: 28% by
Chevron, 5% by Dynegy senior management and 60% by the public (which includes
current Illinova shareholders).  BG

and NOVA will each retain less than a 5% interest in the Dynegy in the form of
Series A Convertible Preferred Stock.

IV.  APPLICABLE LAW

     The action of the Commission in this proceeding is governed by Section
7-204 of the Act relating to the approval of reorganizations.  Under Section
7-204, the term "reorganization" is defined as "any transaction which,
regardless of the means by which it is accomplished, results in a change in the
ownership of a majority of the voting capital stock of an Illinois public
utility; or the ownership or control of any entity which owns or controls a
majority of the voting capital stock of a public utility . . . ." This section
further provides that the "Commission shall not approve any proposed
reorganization if the Commission finds, after notice and hearing, that the
reorganization will adversely affect the utility's ability to perform its duties
under this Act."

     In reviewing the proposed reorganization, the Commission is required by
Section 7-204 to find that:

     (1)  the proposed reorganization will not diminish the utility's ability to
          provide adequate, reliable, efficient, safe, and least-cost public
          utility service;

     (2)  the proposed reorganization will not result in the unjustified
          subsidization of non-utility activities by the utility or its
          customers;

     (3)  costs and facilities are fairly and reasonably allocated between
          utility and non-utility activities in such a manner that the
          Commission may identify those costs and facilities which are properly
          included by the utility for ratemaking purposes;

     (4)  the proposed reorganization will not significantly impair the
          utility's ability to raise necessary capital on reasonable terms or to
          maintain a reasonable capital structure;

     (5)  the utility will remain subject to all applicable laws, regulations,
          rules, decisions, and policies governing the regulation of Illinois
          public utilities;

     (6)  the proposed reorganization is not likely to have a significant
          adverse effect on competition in those markets over which the
          Commission has jurisdiction; and

     (7)  the proposed reorganization is not likely to result in any adverse
          rate impacts on retail customers.

     Section 7-204(c) provides that the Commission shall not approve a
reorganization without ruling on:

                                       5
<PAGE>

                                                                         99-0419

     (i)  the allocation of any savings resulting from the proposed
          reorganization; and

     (ii) whether the companies should be allowed to recover any costs incurred
          in accomplishing the proposed reorganization and, if so, the amount of
          costs eligible for recovery and how the costs will be allocated.

     Section 7-204(f) provides that "in approving any proposed reorganization
pursuant to this Section the Commission may impose such terms, conditions or
requirements as, in its judgment, are necessary to protect the interests of the
public utility and its customers."

     Mr. Smith, Case Manager for Staff, testified that Staff had no objection to
the proposed reorganization since IP satisfied the requirements of Section 7-204
and, therefore, Staff does not oppose the granting of the application.

V.  REQUEST FOR EXPEDITED TREATMENT

     In its application initiating this docket, IP requested that the Commission
expedite its consideration of the proposed Reorganization and issue an order in
this docket by December 31, 1999.  In support of its request, IP pointed out
that the proposed Merger is substantially similar to two reorganizations
recently considered and approved by the Commission, Central Illinois Light
Company with AES Corporation (Docket 98-0882) and MidAmerican Energy Company
with CalEnergy Company (Docket 98-0853), each of which involved the merger of a
traditional utility company with an independent power producer/power marketer.
Each was approved on a procedural schedule substantially shorter than that
allowed under Section 7-204.  Thus, IP sought Commission review and approval of
its application on the same expedited basis as the Commission's proceedings with
regard to the MidAmerican and CILCO transactions, such that an order would be
issued no later than the end of 1999.

     In supplemental testimony filed by Mr. Altenbaumer, the Commission was
informed that the Securities and Exchange Commission ("SEC") elected to forego
review of Illinova's preliminary S-4 registration/proxy statement.  Subject to
minor amendments, this is the document that will be mailed to shareholders to
announce the special shareholders' meeting  and to solicit their votes for
approval of  the Merger.  This decision by the SEC allowed IP to move up the
date of the shareholder meeting for approval of the Merger to October 11, 1999.
The waiting period for the Hart-Scott-Rodino Antitrust Improvements Act filing
was also ended early, on August 24, 1999, meaning the Company is free to proceed
with the merger under that law.  Federal Energy Regulatory Commission ("FERC")
approvals are expected in November 1999.

     Mr. Altenbaumer also described related approvals that are necessary in
order for the Merger to take place.  In particular, closing of the sale of the
Clinton Power Station ("Clinton") is a condition of the Merger.  Therefore, all
regulatory approvals required for the Clinton sale are required prior to
completion of the Merger.  Approval of the Clinton

                                       6

                                                                         99-0419

sale is expected by early October 1999 from the Federal Trade Commission and the
U.S. Department of Justice under the Hart-Scott-Rodino Anti-trust Improvement
Act. FERC approval is expected the first week of November 1999. An Internal
Revenue Service ruling regarding tax issues surrounding the sale of Clinton is
expected the second week of November 1999. The Nuclear Regulatory Commission is
expected to approve the Clinton sale the last week in November. The Commission
approved IP's 16-111(g) filing concerning the sale of Clinton on October 26,
1999.

     It was Mr. Altenbaumer's expectation that all regulatory approvals, other
than the approval of the Commission herein, would be obtained by the end of
November.  Illinova's and Dynegy's shareholders were scheduled to meet to
approve the Merger at shareholder meetings on October 11, 1999.  Consequently,
given the quick pace at which it has been able to obtain regulatory clearances
and approvals, IP now expects the Merger to close by December 31, 1999.  Closing
on this date is also convenient from an accounting perspective, since it is the
actual year end.

VI.  SECTION 7-204 CRITERIA

     A.   IP's ability to provide adequate, reliable, efficient, safe, and
          least-cost public utility service.

     Mr. Altenbaumer stated that the Merger will enhance IP's ability to serve
its customers by enabling IP to address customers' total energy needs.  In
addition, the Merger will make IP a more experienced, innovative, and
competitive company.  This should result in the provision of more diverse and
reliable services.  IP's current efforts to support economic development in
Illinois will continue after the merger.

     Mr. Altenbaumer testified that the Merger will not have an adverse impact
upon IP's ability to provide adequate, reliable, efficient, safe, and least-cost
gas utility service in Illinois.  IP will remain as a separate corporation, and
there will be no change in IP's assets or gas operations as a result of the
Merger.  Any work force reductions are not expected to affect gas utility
operating personnel.  The Merger will not adversely affect IP's ability to
perform its duties related to its regulated gas operations under the Act.
Therefore, in accordance with Section 7-204(b)(1) of the Act, the Merger will
not have an adverse impact upon IP's ability to provide adequate, reliable,
efficient, safe, and least-cost gas utility service in Illinois.  In fact, if
anything, the Merger will enhance IP's ability to provide adequate, reliable,
efficient, safe, and least-cost gas utility service in Illinois, by providing a
stronger financial base and access to a broader base of skills and experience in
the energy markets.

     Mr. Clarke confirmed that there will be no change in the manner in which IP
provides retail gas service in Illinois after the Merger.  IP's assets, gas
operations, and capital structure will remain the same after the Merger.  The
Company's corporate headquarters will remain in Decatur after the Merger as
well.  IP will continue to contribute to the community after the Merger in the
manner and to the extent that it does today.  If there is any impact of the
Merger on IP, it will be an increase in the

                                       7
<PAGE>

                                                                         99-0419

quality and type of services IP provides to its retail natural gas customers as
a result of the stronger financial base and increased base of skills and
experience available to IP.

     Staff witness Smith concluded that the proposed Merger will not adversely
affect IP's ability to provide adequate, reliable, efficient, safe, and least-
cost public utility service.

     B.  UNJUSTIFIED SUBSIDIZATION OF NON-UTILITY ACTIVITIES BY IP OR ITS
         CUSTOMERS.

     Both Mr. Altenbaumer and Ms. Steward, IP's Controller, testified that the
proposed Merger would not result in the unjustified subsidization of non-utility
activities by IP's gas utility or its retail gas customers.  The only direct
effect of the Merger on IP will be a change in the ownership of the common stock
of IP's parent corporation (Illinova) and, ultimately, a change in the ownership
of IP's common stock.

     IP has in place policies and procedures that comply with regulatory
requirements related to non-utility activities of IP and to transactions between
IP and its affiliated interests.  Those policies and procedures will continue to
be followed by the merged companies after the Merger, unless different
procedures are approved by the Commission in Docket 99-0114, the proceeding in
which a proposed new Services and Facilities Agreement among IP and its
affiliates is being considered by the Commission.  These existing policies and
procedures, which have been established or approved by the Commission, are
intended to prevent, among other things, unjustified subsidization of non-
utility or affiliated interest activities by IP's gas utility operations or its
retail gas customers.  Thus, the proposed merger will not result in the
unjustified subsidization of non-utility or affiliated interest activities by
IP's gas utility operations or IP's retail gas customers, consistent with the
requirement of Section 7-204(b)(2).

     Mr. Altenbaumer also explained that IP's accounting policies or procedures
will not change as a result of the Merger.  IP will continue to utilize its
existing accounting policies and procedures related to its regulated gas utility
operations after the Merger, and will continue to use the FERC and ICC Uniform
Systems of Accounts.

     Staff witness Smith concluded that the proposed Merger will not result in
the unjustified subsidization of non-utility activities by IP's gas utility or
its retail gas customers.

     C.   FAIR AND REASONABLE ALLOCATION OF COSTS AND FACILITIES BETWEEN IP'S
          ILLINOIS GAS UTILITY OPERATIONS AND NON-UTILITY ACTIVITIES.

     Ms. Steward testified that there will be no change in the method of
charging employee time or any other expense to gas utility operations, electric
utility operations, non-utility activities, or affiliates as a result of the
Merger.  IP employees are required to charge their time to the corporate
business entity or activity receiving the benefit of their services.  Monthly
reports are produced showing the time and related costs which have been charged
to affiliates, and invoices are generated based on these reports.

                                       8
<PAGE>

                                                                         99-0419

There will be no change in these procedures after the Merger except to the
extent allowed by the Commission in its forthcoming order in Docket 99-0114.

     Ms. Steward described the process through which corporate personnel and
expenses are allocated between the gas and electric utility businesses.  As
described in IP's 1998 ILCC Form 21, expenses are allocated, when possible,
directly to the utility that caused the expense to be incurred.  Common costs
(expenses attributable to both the electric and gas utilities) are allocated
based on certain ratios, such as number of customers, revenues, or revenues plus
expenses.  This allocation process will not change after the Merger.

     Ms. Steward testified that costs and facilities will be fairly and
reasonably allocated between regulated gas utility operations and non-utility
activities in such a manner that the Commission may identify those costs and
facilities which are properly included for gas utility ratemaking purposes.  IP
has in place existing policies and procedures which comply with Commission
requirements related to non-gas utility activities and to affiliate
transactions.  These policies and procedures assure that costs and facilities
are fairly allocated.  They will be adopted by the merged company. Thus, the
requirements of Section 7-204(b)(3) of the Act will be met.

     In addition, Ms. Steward explained that IP is currently in compliance with
the Commission's rules for "Accounting for Non-Public Utility Business of Gas
Utilities" (Part 506).  IP performed an internal audit which determined that IP
is operating in compliance with Part 506.  IP submitted a report to the
Commission on December 1, 1998 reporting the results of that audit, a copy of
which was submitted in this Docket as IP Exhibit 4.1.  Ms. Steward further
stated that the merged companies will continue to comply with applicable
Commission rules regarding affiliate transactions and relationships.

     Staff witness Smith concluded that a fair and reasonable allocation of
costs and facilities will occur after the Merger between IP's Illinois gas
utility operations and non-utility activities.

     D.   IMPAIRMENT OF THE ABILITY OF IP'S GAS UTILITY OPERATIONS TO RAISE
          NECESSARY CAPITAL ON REASONABLE TERMS OR TO MAINTAIN A REASONABLE
          CAPITAL STRUCTURE.

     Mr. Altenbaumer testified that the Merger will have a positive effect on
the long term financial strength of IP as a result of being a part of a larger
global entity and as a result of access to the additional skills and experience
that will be provided by the merger.  This will better position IP to compete in
the energy markets.  Mr. Schultz, IP's Vice President - Finance, provided
additional information concerning the financial impacts of the Merger.  He
stated that the proposed Merger will not impair IP's ability to raise capital on
reasonable terms, and will not impair IP's ability to maintain a reasonable
capital structure.  Those conclusions are based upon two facts, (1) IP's balance
sheet and capitalization will not be changed by the proposed Merger, and (2)
IP's financial ratios will not be changed as a result of the proposed Merger.

                                       9
<PAGE>

                                                                         99-0419

     Mr. Schultz explained that IP will raise capital after the Merger in the
same way it does today: through the issuance of short-term debt or bank lines of
credit, and, with the Commission's approval, through the issuance of long-term
debt.  IP also raises capital through the issuance of preferred stock and will
have the same ability to borrow and to issue preferred stock after the proposed
Merger is complete.  The overall financial strength of the utility is the
primary factor, and is related to the utility's current and expected capital
structure, interest and preferred dividend coverages, and business risk.  The
financial strength is normally reflected through ratings by agencies such as
Moody's, Standard & Poor's, Duff & Phelps, and Fitch IBCA.  IP's commercial
paper is rated P-2 by Moody's, A-2 by Standard & Poor's, D-2 by Duff & Phelps,
and F-2 by Fitch IBCA.  The Company's mortgage bonds are currently rated Baa1 by
Moody's, BBB by Standard & Poor's, BBB by Duff & Phelps, and BBB+ by Fitch IBCA.
The ratings for IP's preferred stock are Baa2 by Moody's, BB+ by Standard &
Poor's, BBB- by Duff & Phelps, and BBB by Fitch IBCA.  All these ratings, with
the exception of IP's preferred stock rating by Standard & Poor's, are within
the "investment grade" category that permits utilities to realize the most
favorable terms and widest investment audience when issuing securities.  Mr.
Schultz testified that it is expected that the ratings will remain at investment
grade levels after the Merger is completed.

     Mr. Schultz noted that IP received positive feedback from the rating
agencies after the announcement of the Merger.  Duff & Phelps placed the
Company's ratings on Rating Watch - Up following the announcement of the Merger.
Standard & Poor's placed IP on CreditWatch with positive implications.  Moody's
confirmed its credit ratings of IP.  A press release from Fitch IBCA states that
it expects the Merger to have little effect on the credit ratings of IP.  This
information establishes that IP's credit ratings will likely remain the same or
improve after the Merger.

     Mr. Schultz explained that IP obtains common equity through retained
earnings.  If greater common equity capital is required, IP can reduce the
amount of dividends paid to its parent company.  If common equity capital is
required by IP in excess of the earnings on common equity, the parent
corporation would have to invest additional capital, either out of cash flow,
retained earnings, borrowings, or the issuance of common equity or preferred
stock by the parent.  IP has not required an investment of common equity capital
beyond its own earnings since it became a subsidiary of Illinova, and does not
anticipate the need for the investment of common equity capital for its retail
natural gas operations within the foreseeable future.  However, if investments
of common equity were required in the future, the larger financial base of the
combined companies would likely make it easier to obtain any needed capital.

     Given these facts, Mr. Schultz concluded that the Merger may enhance IP's
ability to finance on reasonable terms.

     Staff witness Smith concluded that the proposed Merger will not impair IP's
ability to raise capital on reasonable terms, and will not impair its ability to
maintain a reasonable capital structure.

                                                                         99-0419

     E.   CONTINUED APPLICATION OF ALL APPLICABLE LAWS, REGULATIONS, RULES,
          DECISIONS, AND POLICIES GOVERNING THE REGULATION OF ILLINOIS PUBLIC
          UTILITIES TO IP'S GAS UTILITY OPERATIONS.

     Messrs. Altenbaumer and Clarke both testified that the proposed Merger will
not in any manner change IP's status as a gas public utility subject to the
jurisdiction of the Commission.  IP's gas utility operations will remain subject
to all applicable laws, regulations, rules, decisions, and policies governing
the regulation of Illinois public utilities, in accordance with Section 7-
204(b)(5) of the Act.  Thus, Messrs. Altenbaumer and Clarke concluded that the
Merger will cause no change affecting the regulation of IP as a public utility.

     Staff witness Smith concluded that the proposed Merger will not result in a
change  in the regulation of IP, and that all applicable laws, regulations,
rules, decisions, and policies governing the regulation of Illinois public
utilities will continue to apply to IP's gas utility operations after the
Merger.

     F.   IMPACT OF PROPOSED REORGANIZATION ON COMPETITION IN THE NATURAL GAS
          UTILITY MARKET OVER WHICH THE COMMISSION HAS JURISDICTION.

     Mr. Altenbaumer addressed the impact of the Merger on competition in the
natural gas utility market over which the Commission has jurisdiction.  He
explained that while Dynegy or its affiliates provide unregulated gas sales
service in IP's gas service territory, they serve an immaterial share of the
market.  Moreover, Dynegy and its affiliates will continue to offer such service
after the proposed Merger.  IP is required to provide non-discriminatory gas
distribution services to all its retail customers and will not provide
preferential treatment to Dynegy or to Dynegy's retail gas customers in the
provision of retail gas distribution services.  Dynegy does not own any gas
transmission and distribution facilities and does not offer any gas distribution
and transmission service in Illinois.  IP does not provide retail gas service in
Illinois outside of its regulated service territory.  With regard to the
Company's Best Efforts Gas Service, which is a competitive gas service offering
provided to Service Classification 76 customers, IP intends to continue to offer
this service after the Merger.  Therefore, Mr. Altenbaumer concluded that, in
accordance with Section 7-204(b)(6) of the Act, the proposed Merger is not
likely to have an adverse effect on competition in those retail gas markets over
which the Commission has jurisdiction.

     Staff witness Smith concluded that the proposed Merger is not likely to
have an adverse effect on competition in those retail gas markets over which the
Commission has jurisdiction.

     G.   RATE IMPACT OF PROPOSED REORGANIZATIONS ON RETAIL CUSTOMERS.

     Mr. Altenbaumer explained that the Merger is expected to result in cost
reductions, a portion of which would be allocable to IP's gas utility
operations, as well as operating efficiencies.  These cost reductions and
operating efficiencies would serve to delay, and ultimately reduce the level of,
any future requests for gas rate increases.

                                       11
<PAGE>

                                                                         99-0419

IP will not seek treatment for these Merger-related cost savings that is
different than the treatment of any other reduction in the cost of providing gas
service. Thus, the Commission will be able to allocate these savings to IP's gas
customers in any future rate case. Finally, IP's customers' gas costs will not
be adversely affected by the reorganizations. Indeed, the Commission will have
the opportunity to ensure that this is the case in its annual Gas Cost
Adjustment proceedings. In fact, if anything, the Merger is likely to enhance
IP's ability to purchase low cost gas supplies for system supply purposes.
Therefore, Mr. Altenbaumer concluded that, in accordance with Section
7-204(b)(7) of the Act, the proposed Merger is not likely to result in any
adverse rate impacts on IP's retail gas customers.

     Ms. Steward testified that there is no expectation of higher gas rates
caused by this Merger.  In fact, the cost savings and operating efficiencies
anticipated to result from the Merger would serve to delay, and ultimately
reduce the level of, any request for a gas rate increase.  She explained further
that IP is currently earning less than its allowed gas rate of return.  Even
assuming an optimistic level of cost savings resulting from the Merger and a
generous allocation of those savings to the gas utility, IP would continue to
earn less than its allowed rate of return on gas operations after the Merger.
IP is not currently planning to seek an increase in natural gas rates, although
IP will continue to monitor its rate of return on gas operations.  She concluded
that, if anything, the proposed Merger will serve to delay any future request
for a rate increase.

     Staff witness Smith concluded that the proposed Merger is not likely to
result in any adverse rate impacts on the Company's retail gas customers.

     H.   ALLOCATION OF SAVINGS AND COSTS ASSOCIATED WITH THE PROPOSED
          REORGANIZATIONS.

     Section 7-204(c) of the Act requires the Commission to rule on the
allocation of any savings resulting from the proposed Merger.  This Section also
requires the Commission to rule whether the reorganizing companies should be
allowed to recover costs incurred in accomplishing the proposed Merger, and if
so, the amount of costs eligible for recovery and how the costs will be
allocated.

     Mr. Altenbaumer testified that Dynegy and Illinova project annual Merger
synergies of $125 to $165 million.  Two-thirds of these synergies are expected
to come from revenue enhancements through increased utilization of non-regulated
electric generation, marketing, and trading based on the combined assets, and
risk management and arbitrage opportunities.  One-third is expected to come from
cost efficiencies including elimination of duplicate activities, greater
operating efficiencies, and lower capital costs.  Mr. Altenbaumer emphasized
that the objective of the Merger is growth, not cost cutting.  He  testified
that an approximate 5% reduction is anticipated in the combined 6,500 person
workforces of Dynegy and Illinova, mainly in those administrative functions
where there is duplication between the two companies.  The areas primarily
affected will be corporate support and overhead functions, as opposed to
operating personnel.  A joint integration team will be identifying these

                                       12
<PAGE>

                                                                         99-0419

potentially duplicative functions over several months.  IP and Dynegy expect
that normal attrition, new employment opportunities at Dynegy and voluntary
separation or early retirement will mitigate the impact of this reduction on IP
employees.

     IP's position in this case is that 100% of the actual gas utility-related
Merger savings should be flowed through to its gas customers.  IP proposes to do
so through inclusion of those savings in its gas cost of service.  This proposal
will serve to delay the need for a rate increase or reduce any future requested
rate increase.  Mr. Altenbaumer explained that because IP is currently earning
below its authorized rate of return, these savings will likely defer a request
for a rate increase.  He also pointed out that any synergies related to reduced
gas commodity costs would also be flowed directly through in their entirety to
IP's gas customers.

     Mr. Altenbaumer testified that Illinova and Dynegy have incurred and
continue to incur significant transaction costs associated with the proposed
Merger, including investment banking fees, financial consulting costs,
accountants' charges, printing, postage, proxy solicitation, filing fees, and
legal fees.  In addition, there will be costs associated with employee
separations, system integration, employee relocation, and internal and external
communications which will be necessary to achieve the expected savings.  During
1999, Illinova expects to incur $16 million of these costs.  These are necessary
expenses to accomplish the Merger, an allocated portion of which would be
properly recoverable from IP's gas utility customers. Mr. Altenbaumer testified,
however, that IP has committed to not seek to recover, in any future gas rate
case, the costs incurred in accomplishing the Merger.

     Staff witness Smith testified that IP's proposal  satisfied the
requirements of Section 7-204(c).  He agreed that the result of IP's proposal is
that 100% of the actual gas-related Merger savings will be passed on to IP's gas
customers through inclusion in IP's gas cost of service and that no Merger costs
will be passed on to IP's gas customers.

VII.  SECTION 7-204A

     Section 7-204A of the Act sets forth information to be furnished in
connection with certain applications for approval of reorganizations under
Section 7-204.  As detailed in paragraphs 16 through 25 of IP's Petition and the
related exhibits, IP provided to the Commission all the information required
under Section 7-204A.

VIII.  REQUEST FOR RELIEF UNDER SECTION 7-101

     With respect to transactions with affiliates, IP is seeking in this
application approval pursuant to Section 7-101 of the Act of an Interim Services
and Facilities Agreement, which would be effective pending approval of a
permanent Services and Facilities Agreement, approval of which is currently
pending before the Commission in Docket 99-0114.  In addition, IP originally
sought a Commission determination in this proceeding that the Services and
Facilities Agreement which is ultimately approved by

                                       13
<PAGE>

                                                                         99-0419

the Commission in Docket 99-0114 would be deemed to be effective as to IP and
Dynegy after the Merger.

     A.   INTERIM SERVICES AND FACILITIES AGREEMENT

     With regard to the first request for approval of an Interim Services and
Facilities Agreement, Ms. Steward testified that IP and Illinova have a Services
and Facilities Agreement in place which was approved by the Commission in Docket
94-0005.  An addendum was approved in a supplemental order in Docket 94-0005 in
1995, and that approval was extended to December 31, 2000 by a further
supplemental order in 1998. This agreement was originally approved before
electric industry restructuring was contemplated, and only allows for the one-
way provision of services from IP to Illinova.  In this agreement, charges for
facilities and services provided by IP to Illinova are at IP's fully loaded
cost, which includes direct labor expense, labor overheads, employee benefits
participation/processing expenses, other administrative and general overheads
and costs, and interest on cash advances.

     Ms. Steward further explained that on February 26, 1999, IP filed a
petition with the Commission requesting approval of a new Services and
Facilities Agreement between and among Illinova, IP, and all other Illinova
subsidiaries.  Unlike the current agreement, the new agreement is reciprocal
since it provides for services and facilities to be provided both by IP and to
IP.  The new Services and Facilities Agreement generally covers two types of
transactions:  transactions involving facilities and services, and those
involving the sale of assets.  Transactions for use of facilities may involve
office space or various types of equipment.  Services may include, but are not
limited to, financial, personnel, purchasing, information technology,
administrative, and engineering.  Transactions involving sale of assets include
Illinova stock, transfers of real property, tangible personal property, or
intangible assets.  Under the proposed Services and Facilities Agreement,
charges for facilities and services would be set at fully distributed cost
unless that cost is above market price.  If fully distributed cost is above
market price, then the charge would be set above incremental cost but at no more
than market price.  Costs charged on a fully distributed (embedded) cost basis
reflect the direct labor, direct materials, direct purchased services and
certain labor-related indirect costs associated with the related asset or
service.  In general, asset sales would be charged at the fair market value of
the asset unless laws or regulations require a different price.  As with
services and facilities, the charge would be set symmetrically.  Costs that are
specifically attributable to a party would be charged directly to that party.
Costs that have joint benefit to two or more parties (but not all) would be
allocated according to cost causative or benefit derivation measures.

     Ms. Steward explained that in the event that a new Services and Facilities
Agreement is not approved prior to consummation of the Merger, IP has sought
approval in its Petition for an Interim Services and Facilities Agreement, a
copy of which was provided as IP Exhibit 4.2, in order to provide a basis for
services and facilities and asset sales to be provided from Dynegy and its
subsidiaries to IP and vice versa.  This Interim Agreement incorporates all of
the terms and conditions of the

                                       14
<PAGE>

                                                                         99-0419

proposed agreement pending in Docket 99-0114 and would be effective as to any
services and facilities provided by IP to its affiliates, including new
affiliates resulting from the Merger, or vice versa. The Interim Agreement will
terminate and be superseded by the new agreement approved by the Commission when
the new agreement is in fact approved in Docket 99-0114.

     Ms. Steward stated that an Interim Services and Facilities Agreement for IP
was previously approved in Docket 99-0209 and is applicable to services provided
to IP by its new generation affiliate, Illinova Power Marketing, Inc. and the
Interim Agreement is also identical to the Services and Facilities Agreement
pending in Docket 99-0114.  IP agreed to use the Interim Agreement only until
the final order is issued in Docket 99-0114, and then to use the Services and
Facilities Agreement approved by the Commission in that docket.  Thus, IP's
request in this case is identical to its request which was granted in Docket 99-
0209.

     Staff witness Smith filed testimony regarding the Company's request that
the Commission authorize use of the terms in the Services and Facilities
Agreement proposed in Docket 99-0114 for transactions between IP and its
subsidiaries pending approval of an agreement in Docket 99-0114.  It is Staff's
position that an interim agreement is necessary in order for services to flow
both to and from IP.  It is further Staff's position that, rather than utilize
all the terms of the as-yet-unapproved agreement submitted in Docket 99-0114,
the Company should use the pricing terms of the existing Docket 94-0005
agreement until such time as a new agreement is approved in Docket 99-0114.  In
addition, Staff recommends that IP be directed to provide the names of all
affiliated entities who will enter into business transactions with IP.  Staff
further recommends that during the period between consummation of the Merger and
approval of an agreement in Docket 99-0114, the terms of the 94-0005 agreement
should be applicable to transactions between IP and Dynegy as if Dynegy were
inserted in place of Illinova in that agreement.  No additional written
agreement need be executed in order for such transactions to take place for this
interim period.  IP has accepted Staff's position on this issue.

  As a result of a change in the procedural schedule in Docket 99-0114, the
parties have further agreed that the pricing for services and facilities
provided to and from IP pursuant to the interim arrangement approved in this
Order will be trued up to comport with the pricing contained in the services and
facilities agreement ultimately approved in Docket 99-0114.  Specifically,
within 45 days after approval of an agreement in Docket 99-0114 IP will make the
necessary accounting adjustments to implement the pricing in the approved
agreement with the result that all transactions entered into under the interim
arrangement will be priced as if the permanent agreement's pricing terms had
been in effect at the time the transactions took place.  The parties also
agreed, and the Commission concludes that the interim arrangement will expire
June 30, 2000.

     B.   SUBSTITUTION OF DYNEGY FOR ILLINOVA IN AGREEMENT APPROVED IN DOCKET
          99-0114

     With regard to the other request for relief related to the Services and
Facilities Agreement, Ms. Steward explained that the Services and Facilities
Agreement pending in Docket 99-0114 was drafted and filed with the Commission
for approval before the Merger was announced.  The Agreement therefore is not
between IP and Dynegy, but instead between IP and Illinova.  IP requests in this
docket that the Commission conclude that the Services and Facilities Agreement
ultimately approved in Docket 99-0114 be deemed to be applicable to transactions
between Dynegy and IP.  In other words, IP is seeking the Commission's approval
in this case of the substitution of Dynegy for Illinova in whatever agreement is
approved in Docket 99-0114.  IP stated that it would provide a revised version
of such Agreement at the conclusion of Docket 99-0114.

     Staff witness Smith filed testimony opposing this request.  It is Staff's
position that such a  request should be considered by the Commission in Docket
99-0114.  Based on Staff's position, IP has agreed to make its request to
substitute Dynegy for Illinova in Docket 99-0114 and to withdraw that request in
this Docket.

IX.  FINDINGS AND ORDERING PARAGRAPHS

          meaning of the Act;

     (2)  the Commission has jurisdiction over IP and the subject matter of this
          proceeding;

               public utility service;

          (b)  the proposed Reorganization will not result in the unjustified
               subsidization of non-utility activities by IP or its customers
               with respect to IP's gas operations;

          (c)  costs and facilities are fairly and reasonably allocated between

               operations;

          (f)  the proposed Reorganization is not likely to have a significant

          IP to perform its duties under the Act with respect to its gas utility
          operations;

     (7)  any savings resulting from the proposed Reorganization with respect to
          IP's gas utility operations shall be reflected in IP's cost of service
          for recognition in future rate proceedings;

     (8)  transaction costs with respect to IP's gas utility operations portion
          of the Reorganization shall not be recovered from IP's gas utility
          customers;

          Agreement in Docket 99-0114 under the pricing provisions and other
          terms and conditions of the Services and Facilities Agreement approved
          in Docket 94-0005, provided that this interim arrangement will
          terminate the earlier of the date the Services and Facilities
          Agreement is approved by the Commission in Docket 99-0114 or June 30,
          2000; and provided that IP shall provide to Staff the names of all
          affiliated entities who will enter into business transactions with IP

          the rules and regulations of the Commission that are incidental,
          necessary, or appropriate to the performance of any and all acts
          specifically authorized by the Commission in this Order.

     IT IS THEREFORE ORDERED by the Illinois Commerce Commission that approval
is hereby granted to Illinois Power Company, with respect to its gas utility
operations, for the Reorganization that is the result of the transactions in
which Dynegy, Inc. will acquire ownership and control of Illinova Corporation
and, at a future date, Energy Convergence Holding Company will acquire direct

SECURITIES AND EXCHANGE COMMISSION

(RELEASE NO. 35-27122; 70-9553)

CHEVRON CORPORATION, ET AL.
ORDER AUTHORIZING THE ACQUISITION OF COMMON STOCK OF A PUBLIC UTILITY HOLDING
COMPANY

DECEMBER 27, 1999

     Chevron Corporation ("Chevron"), San Francisco, California; Chevron U.S.A.
Inc. ("Chevron USA"), a wholly owned subsidiary of Chevron located in Houston,
Texas; Illinova Corporation ("Illinova"), Decatur, Illinois, an Illinois
public-utility holding company exempt from registration under section 3(a)(1) of
the Public Utility Holding Company Act of 1935, as amended ("Act"); and Energy
Convergence Holding Company ("New Dynegy"), a special purpose subsidiary of
Illinova located in Houston, Texas (collectively "Applicants") have filed an
application with this Commission under sections 9(a)(2) and 10 of the Public
Utility Holding Company Act, as amended ("Act"). The Commission issued a notice
of the filing of the application on November 19, 1999 (HCAR No. 27105).

     In summary, applicants request authority to consummate a series of
transactions that will result in (a) the affiliation of Illinova with Dynegy,
Inc. ("Dynegy"), a nonutility company engaged, among other things, in energy
commodities trading and owning and operating power generation projects and (b)
the establishment of New Dynegy, which would be a subsidiary of Chevron USA,/1/
as a holding company over Illinova and Dynegy./2/ New Dynegy states that it

- ----------------
/1/ Chevron USA currently owns approximately 29% of the outstanding common
    and preferred stock of Dynegy and, upon completion of the proposed
    transactions described below, will own approximately 28% of the common stock
    of New Dynegy.

/2/ New Dynegy currently has no material assets and no public utility assets,
    subsidiaries, or affiliates.

<PAGE>

                                       2

will file for the exemption from registration provided for in section 3(a)(1) of
the Act under rule 2 under the Act after it acquires Illinova. In addition,
Chevron USA intends to apply for an exemption from registration under section
3(a)(3) of the Act.

     Background

     Chevron, a Delaware corporation, manages its investments in, and provides
administrative, financial, and management support to, domestic and foreign
subsidiaries and affiliates that engage in petroleum and chemical operations in
the United States and approximately 90 other countries. Chevron USA is a
Pennsylvania corporation which conducts operations worldwide through its various
divisions. Its principal business activity is in its domestic upstream division
that explores for and produces crude oil, natural gas liquids, and natural gas
in the United States and its domestic downstream division that refines, markets,
and transports gasoline and other refined products in the United States. Neither
Chevron nor Chevron USA currently has any public-utility company subsidiaries,
neither is an affiliate of a public-utility company, and no part of either
company's income is derived from the operations of a public-utility company as
defined by the Act.

     Dynegy is a Delaware corporation which markets and trades natural gas,
natural gas liquids, electricity, and coal. Dynegy also owns power generation
subsidiaries that develop, own, and operate projects that are not electric
utility companies under the Act, including exempt wholesale generators ("EWGs"),
as defined in section 32 of the Act, and companies with interests in qualifying
facilities ("QFs") under the Public Utility Regulatory Policies Act of 1978. The
majority of Chevron's natural gas production, as well as the natural gas liquids
extracted from that gas, are committed to Dynegy under various commercial
agreements. In addition to Chevron USA, Dynegy has two major industrial
<PAGE>

                                       3

shareholders: NOVA Gas Services (U.S.) Inc. ("NOVA") and BG Holdings, Inc.
("BG"), each of which owns approximately 25% of the outstanding voting stock of
Dynegy./3/ Dynegy has no public-utility company operations, subsidiaries or
affiliates.

     Illinova, an Illinois corporation, has three utility subsidiaries, i.e.,
Illinois Power Company ("Illinois Power"); Electric Energy Incorporated
("EEInc"); and Illinova Power Marketing, Inc. ("Illinova Marketing"). In
addition Illinova has five active nonutility subsidiaries, i.e., Illinova
Generating Company ("Illinova Generating"); Illinova Energy Partners, Inc.
("Illinova Energy"); Illinova Insurance Company ("Illinova Insurance"); and
Illinova Business Enterprises ("Illinova Business").

     Illinois Power is Illinova's principal public-utility company subsidiary
and is engaged in the generation, transmission, and distribution of electric
energy and the sale of electric energy at wholesale and retail. Illinois Power
also owns facilities for the distribution of natural gas and is engaged in the
sale of natural gas at retail. It provides traditional utility service subject
to state regulation to approximately 570,000 retail electric and 400,000 retail
gas distribution customers located throughout central Illinois, and also
transmits and sells power at wholesale. All of Illinois Power's utility assets
are located in Illinois. Illinois Power is regulated by the Illinois Commerce
Commission ("ICC") and the Federal Energy Regulatory Commission ("FERC").

     Illinova owns, through Illinova Generating, 20% of the Stock of EEInc, a
public-utility company which generates electricity at a plant located in Joppa,
Illinois for sale to the United States government nuclear processing plant near
Paducah, Kentucky.

- ---------------
/3/ Of the remaining outstanding voting stock of Dynegy, 11% is owned by
    management and the balance is publicly owned.

<PAGE>

                                       4

Approximately 70% of the revenues associated with the Joppa plant are derived
from sales to the United States Department of Energy under a contract that
extends until 2005. Sponsoring utilities, including Illinois Power, purchase
electric power from EEInc in excess of the federal government's requirements.

     Illinova Marketing, a wholly owned subsidiary of Illinova, owns and
operates 3,812 megawatts ("MW") of fossil-fired generating capacity in Illinois
formerly owned by Illinois Power. Illinois Power transferred this capacity
in order to comply with recent Illinois legislation calling for the functional
separation of delivery services and generation services in connection with the
restructuring of the electric utility industry in Illinois. Illinova Marketing
will use this generating capacity primarily to meet the power requirements of
Illinois Power during the period of transition to competition in the electric
power industry established under Illinois law.

     Illinova Generating, which is wholly owned by Illinova, is Illinova's
independent power subsidiary. As noted above, it owns 20% of the stock of EEInc.
It also owns interests in EWGs and QFs located throughout North America, as well
as interests in several generation facilities located outside of North America.

     Illinova Energy brokers and markets electric power and gas. It also
develops and sells energy-related services in the United States and Canada and
owns interests in several gas marketing companies. Illinova  Insurance's primary
business is to insure the risks related to or associated with the business
enterprises of Illinova's subsidiaries. Illinova Business engages in unregulated
energy management software and hardware sales that do fall within the business
scope of Illinova's other subsidiaries.

     Illinova's revenues for 1998 were $2.43 billion, producing a net loss of
$1.38 billion. The public-utility income of Illinova derived from Illinois Power
has been negative
<PAGE>

                                       5

recently and is the primary source of Illinova's consolidated net loss. In 1998,
approximately 73% of Illinova's operating revenues were derived from Illinois
Power's sale, transmission, and distribution of electricity, and 12% of
Illinova's operating revenues were derived from Illinois Power's sale and
transportation of natural gas./4/ Approximately 15% of Illinova's operating
revenues in 1998 came from its other, diversified enterprises.

     Proposed Transaction

     The proposed transaction ("Transaction") involves a combination of Dynegy
and Illinova through a series of mergers that will establish New Dynegy as a
public-utility holding company. New Dynegy will initially have two wholly owned
subsidiaries, an Illinois corporation and a Delaware corporation, that will
serve as acquisition companies. Illinova will be merged with the Illinois
acquisition company, with Illinova surviving the merger, and Dynegy will be
merged with the Delaware acquisition company, with Dynegy surviving the merger.
Upon completion of the Transaction, Illinova and Dynegy will continue to exist,
retaining their respective historical assets and liabilities, but will be wholly
owned subsidiaries of New Dynegy. The parties intend to eliminate Illinova as a
tier in the holding company structure following the Transaction in order to
simplify the New Dynegy holding company system.

     In the Transaction, Dynegy shareholders, other than Chevron USA, will have
the option to elect to receive either (i) .69 shares of New Dynegy Class A
common stock, or (ii) $16.50 in cash, in exchange for each share of Dynegy
common stock. Each Dynegy shareholder will receive cash for any fractional share
regardless of the shareholder's

- --------------------
/4/ Applicants state that the revenues and net income of EEInc are not material
    to Illinova's total public-utility revenues and income.

<PAGE>

                                      6

election. However, New Dynegy will pay cash for only approximately 40% of the
outstanding shares of Dynegy. This will result in conversion of a maximum of
approximately 67.6 million shares of Dynegy common stock into cash. The amount
of cash available will be insufficient to satisfy cash elections completely, and
the cash will be prorated among shareholders electing to receive cash. For each
100 shares of Dynegy common stock for which Dynegy shareholders elect to receive
cash, they will receive cash consideration with respect to no less than 63
shares of Dynegy common stock and no more than 84 shares of Dynegy common stock.
The consideration for the balance of the Dynegy common stock will be New Dynegy
common stock or Series A preferred stock.

     BG and NOVA have elected to receive all cash for their Dynegy shares, but
the 40% limit on the cash portion of the merger consideration will result in
their receiving at least some portion of their consideration in New Dynegy
stock, which BG and NOVA will receive in the form of Series A preferred stock.
NOVA and BG intend to liquidate to liquidate their investment, and Chevron USA
has agreed to purchase from New Dynegy additional shares of New Dynegy's Class B
common stock for an aggregate purchase price of between $200 and $240 million in
order to facilitate this divestment. To the extent that BG and NOVA would
otherwise receive less than 75% cash in exchange for shares of Dynegy common
stock, Chevron USA has agreed to increase its investment, up to a maximum of
$240 million. As a result of these repurchase transactions, Chevron USA's
ownership interest in New Dynegy upon completion of the Transaction will be
approximately 28%.

     Chevron USA's equity interest in New Dynegy will be in the form of Class B
common stock. These shares give Chevron USA the right to elect three of the
fourteen
<PAGE>

                                       7

members of the New Dynegy Board of Directors./5/ They also give Chevron USA the
right to block New Dynegy from entering into certain transactions ("Blocking
Rights"), including (a) a sale of all or substantially all of the liquids
business or the gas marketing business of New Dynegy so long as Chevron USA's
long-term sale contracts with New Dynegy remain in effect, and (b) mergers,
acquisitions, and other business combinations, sales of businesses or assets,
and major transactions, including joint ventures, valued at over $1 billion or
one-quarter of New Dynegy's market capitalization, whichever is greater. If
Chevron USA exercises these blocking rights twice within a 24-month period or
three times during any time period, either at the Board of Directors level or on
the shareholder level (other than to block changes to the constituent
instruments of New Dynegy which would materially affect these rights), New
Dynegy will have certain rights to purchase Chevron USA's shares or require
Chevron USA either to sell its shares of New Dynegy to a third party or to give
up any future exercise of the Blocking Rights.

     The acquisition of Illinova by New Dynegy will be accomplished by an
exchange of New Dynegy Class A common stock for Illinova common stock.
Specifically, Illinova shareholders will receive one share of New Dynegy Class A
common stock for each share of Illinova common stock that they own.

     Applicants state that all requisite corporate and shareholder approvals for
the Transaction have been obtained. Specifically, the Illinova Board of
Directors approved the Transaction on June 13, 1999, the Dynegy Board of
Directors approved the Transaction on June 14, 1999, and the shareholders of
Illinova and Dynegy approved the

                                       8

Transaction on October 11, 1999. In addition, Applicants note that each of
Dynegy and Illinova have been advised by professional investment advisors that
the consideration to be paid in the Transaction is fair./6/ Applicants state
that the Transaction does not affect the mortgage debt of Illinova Power, which
continues to be secured by liens on its physical property, or the rights of the
holders of that debt or of other debt issued by Illinois Power. Applicants
further state that the Transaction does not affect the rights of holders of debt
issued by Dynegy.

     Applicants identify a number of financial and organizational benefits that
are expected to accrue from the Transaction./7/ Illinova states that it seeks
this business combination with Dynegy in order to achieve financial, managerial
and operating benefits that will position Illinova and Illinois Power to compete
in the increasingly competitive wholesale and retail energy markets that have
developed as a result of state and federal regulatory change. In these
restructured markets, Illinova expects that customers, whether wholesale or
retail, will purchase generated electricity separately from transmission and
distribution services. In the case of electricity, recently enacted Illinois
legislation provides that customers will have a choice in selecting their
electricity provider, regardless of the geographic proximity of the source of
physical generation to the customer. Illinova believes Dynegy will complement
the utility operations of Illinois Power and allow Illinova to combine its small
energy trading operations with the larger trading and marketing operations of
Dynegy. Applicants state that a broader slate of

                                       9

energy products and an effective marketing organization will permit Illinova to
remain competitive both for customers and for capital needed for exempt
operations and public-utility company operations.

     Applicants assert that the existence of the New Dynegy Class B common
stock will not result in an unnecessarily complicated capital structure or
voting power that is unfairly or inequitably distributed among system security
holders. Applicants state that the Class B common stock will be issued
exclusively to Chevron USA to be responsive to the role of Chevron USA as a
strategic investor in New Dynegy.

     Applicants state that there will be no effect on the legal title to New
Dynegy assets or the responsibilities for the liabilities of New Dynegy or its
subsidiaries. The record also notes that the Class B common stock is identical
in all respects to Class A common stock, except with respect to the Block Rights
and with respect to certain restrictions on the transfer or conversion of the
Class B common stock. Applicants further note that the terms of all of these
securities have been disclosed to the public and to the shareholders of Dynegy
and Illinova in the New Dynegy Registration Statement filed with the Commission.

     Applicants state that the FERC, the ICC, the U.S. Department of Justice
("DOJ"), and the Federal Trade Commission ("FTC") have jurisdictions over the
proposed transactions. Specifically, the FERC approved on November 10, 1999,
among other things, the transfer of control of Illinova's utility assets to New
Dynegy. On November 23, 1999, the ICC granted Illinois Power authorization to
transfer control over its gas utility operations to New Dynegy. In addition,
Chevron, Dynegy, and Illinova have each made the necessary filings with the DOJ
and the FTC under the Hart Scott-Rodino
<PAGE>

                                      10

Antitrust Improvements Act of 1976, and on August 24, 1999 were informed by the
FTC that early termination of the waiting periods under those filings had been
granted.

     Fees and expenses in the estimated amount of approximately $46 million are
expected to be incurred in connection with the proposed transactions.

             EXCLUDING GENERATION TO BE DIVESTED BY ILLINOIS POWER

     This Exhibit contains forward-looking information based on current
expectations and plans that involve risks and uncertainties. Forward-looking
information includes, among other things, financial forecasts and projections,
statements concerning the impact of regulatory changes, plans for the Clinton
Facility, divesting fossil-fired generation and success in addressing Year 2000
issues. Although Illinova and Illinois Power (collectively "Illinova") believe
these forward-looking statements are reasonable projections for their business
planning purposes and to inform regulatory agencies concerning the scope of
Illinova's public utility operations excluding generation to be divested by
Illinois Power, these projections are made for the latter purpose only.
Illinova's public utility business is dependent on various regulatory issues,
general economic conditions and future trends, and these factors can cause
actual results to differ materially from the forward-looking statements.
