    which shares of Class A common stock, par value $.01 per share ("AES Chigen
    Class A Common Stock"), of AES China Generating Co. Ltd., a Bermuda company
    ("AES Chigen"), may be converted in the amalgamation of AES Acquisition Co.
    Ltd., a Bermuda company ("AES Sub") and wholly-owned subsidiary of The AES
    Corporation, a Delaware corporation ("AES"), with AES Chigen (the

(3) Estimated solely for the purpose of calculating the registration fee
    pursuant to Rule 457(f)(1) and Rule 457(c) of the Securities Act of 1933, as

                          TO BE HELD ON MARCH 31, 1997
 
To Our Shareholders:
 
     Notice is hereby given that a Special Class Meeting of Holders of Class A
Common Stock (the "Class A Meeting") of AES China Generating Co. Ltd., a Bermuda
company ("AES Chigen"), and a Special General Meeting of the Shareholders (the
"Special Meeting") of AES Chigen, will be held at 1001 North 19th Street,
Arlington, Virginia 22209, on March 31, 1997. The Class A Meeting will commence
at 1 p.m., local time, and the Special Meeting will commence immediately after
the conclusion of the Class A Meeting. The Class A Meeting and the Special
Meeting, and any adjournments or postponements thereof, are being held for the
following purpose:
 
     To consider and vote upon the adoption and approval of the Amended and
     Restated Agreement and Plan of Amalgamation dated as of November 12,
     1996 (the "Amalgamation Agreement") among AES Chigen, The AES
     Corporation, a Delaware corporation ("AES"), and AES Acquisition Co.
     Ltd., a Bermuda company and a wholly-owned subsidiary of AES ("AES
     Sub"), pursuant to which AES Sub will amalgamate with and into AES
     Chigen (the "Amalgamation"), and each share of AES Chigen Class A
     Common Stock outstanding immediately prior to the Amalgamation will be
     canceled in consideration of the right to receive a fraction of a
     share of Common Stock, par value $0.01 per share, of AES, determined
     as provided in the Amalgamation Agreement.
 
     The Board of Directors of AES Chigen has determined that the Amalgamation
is in the best interests of the holders of Class A Common Stock. For purposes of
sec.106 of the Companies Act 1981 of Bermuda, as amended, it has been determined
that the fair value of the AES Chigen Class A Common Stock is $13.05 which is
the minimum value per share to be received by holders of AES Chigen Class A
Stock in the Amalgamation. Holders of AES Chigen Class A Common Stock who do not
vote in favor of the Amalgamation will have the right to seek an appraisal of
the fair value of their shares in connection with the completion of the
Amalgamation. See "Rights of Dissenting Shareholders" in the accompanying Proxy
Statement/Prospectus.
 
     Holders of Class A Common Stock and shareholders of record at the close of
business on February 18, 1997 will be entitled to notice of, and to vote at, the
Class A Meeting and the Special Meeting, respectively, and any adjournments or
postponements thereof. Whether or not you plan to attend, please sign, date and

return of your proxy will assist us in preparing for the Class A Meeting and the
Special Meeting.

                            ------------------------
 
THE AES CORPORATION
 
     With a presence in over 35 countries, AES is a global power company
committed to supplying electricity to customers world-wide in a socially
responsible way. AES, based in Arlington, Virginia, markets power principally
from electric generating facilities that it develops, owns and operates. AES was
one of the original entrants in the independent power market and today is one of
the world's largest global power companies, based on net equity ownership of
generating capacity (in megawatts) in operation or under construction.
 
     Over the last six years, AES has experienced significant growth. This
growth has resulted primarily from the development and construction of new
plants ("greenfield development") and also from the acquisition of existing
plants, primarily through competitively bid privatization initiatives outside
the United States.
 
     In part, AES's strategy in helping meet the world's need for electricity is
to participate in competitive power generation markets as they develop either by
greenfield development or by acquiring and operating existing facilities in
these markets.
 
     Other elements of AES's strategy include:
 
     - Supplying energy to customers at the lowest cost possible, taking into
       account factors such as reliability and environmental performance.
 
     - Constructing or acquiring projects of a relatively large size (generally
       larger than 100 megawatts).
 
     - Entering into power sales contracts with electric utilities or other
       customers with credit strength.
 
     AES also strives for operating excellence as a key element of its strategy,
which it believes it accomplishes by minimizing organizational layers and
maximizing company-wide participation in decision-making. AES has attempted to
create an operating environment that results in safe, clean and reliable
electricity generation. Because of this emphasis, AES prefers to operate all
facilities which it develops or acquires; however, there can be no assurance
that AES will have operating control of all of its facilities in the future.

     AES, a corporation organized under the laws of Delaware, was formed in
1981. The principal office of AES is located at 1001 North 19th Street,
Arlington, Virginia 22209, and its telephone number is (703) 522-1315.
 
AES ACQUISITION CO. LTD.
 
     AES Sub is a Bermuda company and a wholly-owned subsidiary of AES formed on
November 22, 1996 solely for the purpose of consummating the Amalgamation and
the other transactions contemplated by the Amalgamation Agreement. AES Sub has
no assets or business and has not carried out any activities to date other than
activities incident to its formation and in connection with the Amalgamation and
the other transactions contemplated by the Amalgamation Agreement. The principal
executive offices of AES Sub are the same as those of AES.
 
AES CHINA GENERATING CO. LTD.
 
     AES Chigen is a leading independent power generation company in China and
one of the few international developers that has successfully completed the
development of electric power projects in the country. AES Chigen was founded in
December 1993 by AES to serve as the exclusive vehicle for AES to develop,
acquire, finance, construct, own and operate electric power generation
facilities in the PRC. AES currently holds approximately 48% of the equity
capital of AES Chigen and AES, as the holder of all of the AES Chigen Class B
Common Stock, has the right to elect one half of the Board of Directors of AES
Chigen. Thus, AES may be deemed to control the management and operation of AES
Chigen. AES does not, however, have control of AES Chigen in respect of approval
of the Amalgamation; pursuant to the Stock Purchase and Shareholder's Agreement,
AES was required to obtain the consent of the Class A Directors of AES Chigen
prior to entering into the Amalgamation Agreement. See "AES Chigen's
Relationship with AES -- Stock Purchase and Shareholder's Agreement." In
addition, approval of the holders of AES Chigen Class A Common Stock is
required.
 
     To respond to significant opportunities in China, AES, through a
wholly-owned subsidiary, opened an office in Hong Kong in early 1993. Following
the incorporation of AES Chigen, AES purchased shares of AES Chigen Class B
Common Stock for $50.0 million and, in early 1994, AES Chigen completed an
initial public offering of shares of its Class A Common Stock, which provided
AES Chigen with net proceeds, after underwriting commissions and discounts, of
$151.9 million.
 
     Since commencing business, AES Chigen has committed $259.6 million and as
of January 31, 1997 has invested $165.7 million in eight power projects in
operation or under construction in the PRC having an aggregate nameplate
capacity of approximately 818 MW (approximately 422 MW of which is attributable
to AES Chigen's interests in certain joint venture enterprises). These joint
ventures' projects include coal, oil and natural gas-fired and hydropower plants
located in six different provinces in China.
 
     AES Chigen plans to build upon its position as a leading independent power
producer in the PRC through the continued development of and investment in
electric power projects. AES Chigen has signed joint venture contracts and is in
various stages of negotiation to develop three additional power projects with an
aggregate nameplate capacity of approximately 2,900 MW (approximately 805 MW of
which is attributable to the Company's interests in the proposed project
companies). For a discussion of certain restraints on AES Chigen's future
funding and development of projects after the Amalgamation is effective, see
"AES Chigen's Relationship with AES -- Material Effects of the Amalgamation."
 
     AES Chigen's principal offices are located at 3/F (W), Golden Bridge Plaza,
No. 1(A) Jianguomenwai Avenue, Beijing 100020, People's Republic of China. AES
Chigen's telephone number is (8610) 6508-9619.

February 18, 1997 are entitled to notice of and to vote at the Special Meeting.
There were 8,171,268 shares of AES Chigen Class A Common Stock and 7,500,000
shares of AES Chigen Class B Common Stock outstanding at the close of business
on February 18, 1997. Holders of each class of AES Chigen Common Stock are
entitled to one vote per share. A quorum for the Class A Meeting consists of a

by proxy and representing in excess of 50% of the total issued shares of the AES
Chigen Class A Common Stock. A quorum for the Special Meeting consists of a

outstanding shares of each class voting as a separate class, and at least a
majority of all shares regardless of class represented and entitled to be voted
at a meeting of shareholders at which a quorum is present, is required for the
approval of the Amalgamation Agreement and the Amalgamation.
 
     As of February 1, 1997, the directors and executive officers of AES and AES
Chigen owned an aggregate of 9,100 shares (or less than 1%) of AES Chigen Class
A Common Stock entitled to vote at the Special Meeting and the Class A Meeting.
All directors and executive officers entitled to vote intend to vote their

Chigen Class B Common Stock. AES has agreed in the Amalgamation Agreement to
vote all the outstanding shares of AES Chigen Class B Common Stock in favor of
the Amalgamation Proposal. AES will do so by written consent in lieu of a
special meeting of the Class B shareholders and will vote such shares in favor
of adoption and approval of the Amalgamation Proposal at the Special Meeting.
 
THE AMALGAMATION
 
     At the Effective Time (as defined in "-- Effective Time of Amalgamation;
Closing Date"), and upon the terms and subject to the conditions set forth in
the Amalgamation Agreement, AES Sub will be amalgamated with and into AES
Chigen, in accordance with the Companies Act 1981 of Bermuda, as amended (the
"Companies Act"). At and after the Effective Time, AES Chigen will continue in
the form of the amalgamated company (the "Amalgamated Company") and will operate
under the name AES China Generating Co. Ltd.
 
     EXCHANGE RATIO.  If the Amalgamation Proposal is approved and the
Amalgamation is consummated, each issued and outstanding share of AES Chigen
Class A Common Stock will be canceled in consideration of the right to receive
AES Common Stock in the ratio of 0.2900 of a share of AES Common Stock;
provided, that should the average closing price of AES Common Stock on the NYSE
(with fractions expressed as a decimal rounded to the nearest one
ten-thousandth) over the 15 consecutive trading day period ending at the close
of trading on the third trading day immediately prior to the date of the Special
Meeting (the "Average Closing Price") be less than $45.00, shares of AES Chigen
Class A Common Stock will be canceled in consideration of the right to receive a
fraction of a share of AES Common Stock (expressed as a decimal rounded to the
nearest one ten-thousandth) as is determined by dividing $13.05 by the Average
Closing Price (the "Exchange Ratio" or the "Amalgamation Consideration"). AES
has the right not to consummate the Amalgamation if the Exchange Ratio, as so
determined, is greater than 0.3100. Fractional shares of AES Common Stock will
not be issuable in connection with the Amalgamation. AES Chigen shareholders
will

Stock. See "Description of the Amalgamation Agreement -- The Amalgamation
Consideration."

(1) AES will have the right not to consummate the Amalgamation if the Exchange
    Ratio is greater than 0.3100.
 
(2) For each additional one dollar increase in the Average Closing Price of AES
    Common Stock, the value to be received for each share of AES Chigen Class A
    Common Stock increases by $0.29.
 
     EFFECTIVE TIME OF AMALGAMATION; CLOSING DATE.  The Amalgamation will become
effective at such time as a certificate of amalgamation (the "Certificate of
Amalgamation") is duly issued by the Bermuda Registrar of Companies (the time
the Amalgamation becomes effective being the "Effective Time"). The closing of
the Amalgamation will take place at 10:00 a.m. on a date to be specified by AES
or AES Sub, which may be on, but will be no later than the third business day
after, the day on which there shall have been satisfaction or waiver of the
conditions to the obligations of the parties contained in the Amalgamation
Agreement (the "Closing Date"), unless another date or place is agreed to in
writing. See "Description of the Amalgamation Agreement -- Conditions."
 
                                        4
<PAGE>   12
 
     CONDITIONS TO CONSUMMATION OF THE AMALGAMATION.  The respective obligations
of AES, AES Sub and AES Chigen to consummate the Amalgamation are subject to the
satisfaction of various conditions, including among others, approval and
adoption of the Amalgamation Agreement and the transactions contemplated thereby
by the requisite votes of shareholders of AES Chigen, the absence of any order,
executive order, stay, decree, judgment or injunction, or statute, rule or
regulation which makes illegal or otherwise prohibits the Amalgamation, the
effectiveness of the Registration Statement and the absence of any stop order
suspending the effectiveness of the Registration Statement, and evidence that
the shares of AES Common Stock registered thereby shall be listed on the NYSE at
the Effective Time. AES's and AES Sub's obligations are further subject to,
among other conditions, the absence of any Material Adverse Change in respect of
AES Chigen, the Exchange Ratio not exceeding 0.3100 and the number of shares of
AES Chigen Class A Common Stock held by persons who do not vote in favor of the
Amalgamation and who comply with Bermuda law concerning the right of holders to
dissent and require an appraisal not exceeding 10% of the total issued and
outstanding shares of AES Chigen Class A Common Stock. AES Chigen's obligations
are further subject to, among other conditions, its financial advisor not having
withdrawn its opinion. See "Description of the Amalgamation
Agreement -- Conditions" and "Recent Developments -- Certain Litigation in
Respect of the Amalgamation."
 
     ACCOUNTING TREATMENT.  The Amalgamation will be accounted for as a purchase
under generally accepted accounting principles.
 
     REGULATORY APPROVALS.  AES and AES Chigen are aware of no U.S. federal,
state or local government permits, licenses or regulatory approvals material to
their respective businesses that must be obtained for consummation of the
Amalgamation, other than compliance with federal and state securities laws. The
Amalgamation is not subject to the pre-merger notification provisions of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"). AES, AES Sub and AES Chigen have each agreed to use their best efforts to
obtain any other regulatory approvals.
 
     AES and AES Chigen are aware of no PRC national or local laws, regulations,
permits, licenses or regulatory approvals that a foreign company must obtain for
consummation of an amalgamation in which AES Chigen is the surviving entity.
 
     REASONS FOR THE AMALGAMATION.
 
     The Board of Directors of AES approved the Amalgamation because the Board
believes it will enhance the potential for future development and financing of
power projects in the PRC by AES, through AES Chigen or other subsidiaries or
affiliates of AES. The Amalgamation will allow AES Chigen, or any other
subsidiary or affiliate of AES pursuing business opportunities in the China
power market, to (i) direct its business strategy more appropriately toward
sustainable long-term performance, with less emphasis paid to short-term
earnings performance, (ii) reduce administrative and operating costs, (iii)
enhance AES Chigen's business performance through utilization of greater
resources available to the combined companies, and (iv) use AES Common Stock as
part of its compensation program to attract and retain qualified people at AES
Chigen.
 
     In addition, the Board of AES believes the Amalgamation will significantly
improve the liquidity for AES Chigen shareholders arising from low trading
volumes in AES Chigen Class A Common Stock, while reducing the share price
volatility associated with operating AES Chigen as a public company focused
solely on a developing market such as the PRC.
 
     The Amalgamation will allow AES Chigen's shareholders to continue to share
in a portion of the potential long-term gains in AES Chigen through the
ownership of AES Common Stock following the Amalgamation, while diversifying
their investment through ownership of common stock of AES, which invests in a
variety of countries, and which has a more mature business.

     RECOMMENDATION OF THE BOARD OF DIRECTORS.
 
     A Special Committee of the Board of Directors of AES Chigen (the "Special
Committee") comprised of the directors elected by the holders of the AES Chigen
Class A Common Stock (a) has determined that the Amalgamation is in the best
interests of AES Chigen and the holders of the AES Chigen Class A Common Stock
and has recommended that the AES Chigen Board of Directors approve and adopt the
Amalgamation Agreement and approve the transactions contemplated thereby and (b)
has recommended that the AES Chigen Board of Directors recommend to the holders
of the AES Chigen Class A Common Stock that they approve and adopt the
Amalgamation Agreement.
 
     The Board of Directors of AES Chigen, based on the recommendation of the
Special Committee, has determined that the Amalgamation is in the best interests
of AES Chigen and its shareholders and has approved and adopted the Amalgamation
Agreement and approved the transactions contemplated thereby and directed that
the Amalgamation Agreement and the Amalgamation be submitted to a vote of the
shareholders of AES Chigen.
 
     OPINION OF THE SPECIAL COMMITTEE'S FINANCIAL ADVISOR.
 
     Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") has
delivered an opinion to the Special Committee dated as of November 12, 1996
stating that, as of the date of its opinion, the proposed consideration to be
received by the holders of the AES Chigen Class A Common Stock in the
Amalgamation is fair to such holders from a financial point of view. A copy of
this opinion, which sets forth certain assumptions, qualifications and
limitations is attached as Appendix B hereto and should be read in its entirety.
See "The Amalgamation -- Opinion of the Special Committee's Financial Advisor."
 
     CERTAIN LITIGATION IN RESPECT OF THE AMALGAMATION.
 
     A lawsuit has been filed in the Court of Chancery of the State of Delaware
against AES claiming a breach of fiduciary duty by AES as a controlling
shareholder of AES Chigen and seeking, among other things, to enjoin AES from
consummating the Amalgamation. AES Chigen is not a defendant in the lawsuit. AES
has informed AES Chigen that it believes that it has meritorious defenses to the
lawsuit and intends to defend against it vigorously. The parties to the
Amalgamation Agreement intend to proceed with the Amalgamation, subject to
receipt of shareholder approval and the satisfaction of the other conditions
contained in the Amalgamation Agreement, unless enjoined. See "Recent
Developments -- Certain Litigation in Respect of the Amalgamation."
 
MATERIAL PROVISIONS OF THE AMALGAMATION AGREEMENT
 
     REPRESENTATIONS AND WARRANTIES.  The Amalgamation Agreement contains
various representations and warranties of AES, AES Sub and AES Chigen. See
"Description of the Amalgamation Agreement -- Representations and Warranties."
 
     NO SOLICITATION.  The Amalgamation Agreement provides that the Board of
Directors of AES Chigen will not solicit, initiate or participate in
negotiations regarding a "Takeover Proposal" unless the failure so to act would
be inconsistent with its fiduciary duties to AES Chigen or to the holders of AES
Chigen Class A Common Stock. The Amalgamation Agreement provides that AES Chigen
shall promptly notify AES of any Takeover Proposal, the material terms of such
Takeover Proposal and the identity of the person making such Takeover Proposal,
and shall keep AES fully informed of the status and details of any such Takeover
Proposal. See "Description of the Amalgamation Agreement -- No Solicitation."
 
     TERMINATION.  The Amalgamation Agreement may be terminated and the
Amalgamation and the other transactions contemplated thereby may be abandoned at
any time prior to the Effective Time, whether before or after approval of the
Amalgamation Agreement by shareholders, by mutual written consent of AES and AES
Chigen or by either party (i) if as a result of the failure, occurrence or
existence of any of the conditions set forth in the Amalgamation Agreement the
Amalgamation shall not have occurred on or before April 30, 1997 (provided,
however, that this right to terminate the Amalgamation Agreement is not
available to any
 
                                        6
<PAGE>   14
 
party whose failure to perform any of its obligations under the Amalgamation
Agreement results in the failure, occurrence or existence of any such condition)
or (ii) if any Governmental Entity shall have issued an Order permanently
enjoining, restraining or otherwise prohibiting the Amalgamation and such Order
shall have become final and nonappealable. AES and AES Chigen each have certain
further rights to terminate the Amalgamation Agreement as set forth in
"Description of the Amalgamation Agreement -- Termination."
 
     FEES AND EXPENSES OF THE AMALGAMATION.  Under the Amalgamation Agreement,
except as provided below, all fees and expenses incurred in connection with the
Amalgamation, the Amalgamation Agreement and the transactions contemplated
thereby shall be paid by the party incurring such fees or expenses, whether or
not the Amalgamation is consummated. However, AES Chigen shall pay, or cause to
be paid, to AES all of AES's out-of-pocket expenses in an amount up to but not
to exceed $750,000 (the "Expenses") upon demand if (i) AES terminates the
Amalgamation Agreement as a result of the Special Committee's approval or
recommendation of a Takeover Proposal, (ii) AES Chigen terminates the
Amalgamation Agreement and enters into an agreement with respect to a Takeover
Proposal or (iii) prior to the termination of the Amalgamation Agreement (other
than by AES Chigen as a result of a material, incurable breach by AES), a
Takeover Proposal shall have been made, and within one year of such termination,
AES Chigen enters into an agreement with respect to, approves or recommends or
takes any action to facilitate, such Takeover Proposal.
 
     DISSENTERS' RIGHTS.  Any holder of shares of AES Chigen Class A Common
Stock who does not vote in favor of the Amalgamation and who is not satisfied
that he or she has been offered the fair value of his or her shares may within
one month of the giving of the notice of the Class A Meeting and the Special
Meeting apply to the Supreme Court of Bermuda to appraise the fair value of such
holder's shares. There is no right of appeal from an appraisal by the Court.
Such shareholder will receive the value appraised by the Court only if the
Amalgamation is completed. See "Rights of Dissenting Shareholders" and "The
Class A Meeting and the Special Meeting."
 
     RESALE RESTRICTIONS.  All shares of AES Common Stock received by AES Chigen
shareholders in the Amalgamation will be freely transferable, except that shares
of AES Common Stock received by persons who are deemed to be "affiliates" (as
such term is defined under Rule 145 of the Securities Act) of AES Chigen at the
time of the Class A Meeting and the Special Meeting may be resold by them only
in certain permitted circumstances. See "The Amalgamation -- Resale
Restrictions."
 
MATERIAL TAX CONSEQUENCES
 
     It is expected that the Amalgamation will constitute a reorganization
within the meaning of Section 368(a)(1)(B) of the Internal Revenue Code of 1986,
as amended (the "Code"). Assuming that the Amalgamation so qualifies and that
certain proposed Passive Foreign Investment Company regulations are applicable
(see "Material Tax Consequences -- United States Federal Income
Taxation -- Possible Application of Passive Foreign Investment Company Rules"),
a U.S. holder of AES Chigen Class A Common Stock will not recognize gain or loss
upon the exchange (except with respect to cash received in lieu of a fractional
share of AES Common Stock). See "Material Tax Consequences -- United States
Federal Income Taxation."
 
COMPARISON OF SHAREHOLDER AND STOCKHOLDER RIGHTS
 
     Upon consummation of the Amalgamation, holders of AES Chigen Class A Common
Stock immediately prior to the Effective Time will become stockholders of AES.
Various differences exist between the rights of shareholders of AES Chigen and
the rights of stockholders of AES. These differences result from differences
between Bermuda and Delaware law and differences between the organizational
documents of AES and AES Chigen. See "Comparison of Shareholders' and
Stockholders' Rights."

                                  RISK FACTORS
 
AES RISK FACTORS
 
     Holders of AES Chigen Class A Common Stock should carefully consider the
following factors in connection with their consideration of the Amalgamation and
their receipt of AES Common Stock upon consideration thereof. Certain of such
factors also apply to AES Chigen and would continue to so apply in the event the
Amalgamation is not consummated. See also "AES Chigen Risk Factors" below.
 
     LEVERAGE AND SUBORDINATION
 
     AES and its subsidiaries had approximately $2.1 billion of outstanding
indebtedness at September 30, 1996. As a result of AES's level of debt, AES
might be significantly limited in its ability to meet its debt service
obligations, to finance the acquisition and development of additional projects,
to compete effectively or to operate successfully under adverse economic
conditions, although the Company believes it will be able to meet such
obligations. As of September 30, 1996, AES had a consolidated ratio of total
debt to total book capitalization (including current debt) of approximately 75%.
 
     DOING BUSINESS OUTSIDE THE UNITED STATES
 
     AES's involvement in the development of new projects and the acquisition of
existing plants in locations outside the United States is increasing and most of
AES's current development and acquisition activities are for projects and plants
outside the United States. AES, through subsidiaries, affiliates and joint
ventures, including AES Chigen, has ownership interests in 27 power plants
outside the United States in operation or under construction. Five of such power
plants are located in Argentina; four in Brazil; two in England; two in Northern
Ireland; two in Pakistan; eight in the PRC (through AES Chigen); three in
Hungary; and one in Kazakhstan.
 
     The financing, development and operation of projects outside the United
States entail significant political and financial uncertainties (including,
without limitation, uncertainties associated with first-time privatization
efforts in the countries involved, currency exchange rate fluctuations, currency
repatriation restrictions, currency inconvertibility, political instability,
civil unrest, and expropriation) and other structuring issues that have the
potential to cause substantial delays in respect of or material impairment of
the value of the project being developed or operated, which AES may not be
capable of fully insuring or hedging against. The ability to obtain financing on
a commercially acceptable non-recourse basis in developing nations may also
require higher investments by AES than historically have been the case. In
addition, financing in countries with less than investment grade sovereign
credit ratings may also require substantial participation by multilateral
financing agencies. There can be no assurance that such financing can be
obtained when needed.
 
     The uncertainty of the legal environment in certain countries in which AES,
its subsidiaries and its affiliates are or in the future may be developing,
constructing or operating could make it more difficult for AES to enforce its
respective rights under agreements relating to such projects. In addition, the
laws and regulations of certain countries, such as the PRC, may limit AES's
ability to hold a majority interest in some of the projects that it may develop
or acquire. International projects owned by AES may, in certain cases, be
expropriated by applicable governments. Although AES may have legal recourse in
enforcing its rights under agreements and recovering damages for breaches
thereof, there can be no assurance that any such legal proceedings will be
successful.
 
     COMPETITION
 
     The global power production market is characterized by numerous strong and
capable competitors, many of whom may have extensive and diversified
developmental or operating experience (including both domestic and international
experience) and financial resources similar to or greater than AES. Further, in
recent years, the power production industry has been characterized by strong and
increasing competition with respect to both obtaining power sales agreements and
acquiring existing power generation assets. In certain markets, such as the
United States and Argentina, these factors have caused reductions in prices
contained in new
 
                                       13
<PAGE>   21
 
power sales agreements and, in many cases, have caused higher acquisition prices
for existing assets through competitive bidding practices. The evolution of
competitive electricity markets and the development of highly efficient
gas-fired power plants have also caused, or are anticipated to cause, price
pressure in certain power markets where AES sells or intends to sell power.
There can be no assurance that the foregoing competitive factors will not have a
material adverse effect on AES.
 
     DEVELOPMENT UNCERTAINTIES
 
     The majority of the projects that AES develops are large and complex and
the completion of any such project is subject to substantial risks. Development
can require AES to expend significant sums for preliminary engineering,
permitting, legal and other expenses in preparation for competitive bids which
AES may not win or before it can be determined whether a project is feasible,
economically attractive or capable of being financed. Successful development and
construction is contingent upon, among other things, negotiation on terms
satisfactory to AES of engineering, construction, fuel supply and power sales
contracts with other project participants, receipt of required governmental
permits and consents and timely implementation and satisfactory completion of
construction. There can be no assurance that AES will be able to obtain new
power sales contracts, overcome local opposition, if any, obtain the necessary
site agreements, fuel supply and ash disposal agreements, construction
contracts, steam sales contracts, licenses and certifications, environmental and
other permits and financing commitments necessary for the successful development
of its projects. There can be no assurance that development efforts on any
particular project, or AES's efforts generally, will be successful. If these
development efforts are not successful, AES may abandon a project under
development. At the time of abandonment, AES would expense all capitalized
development costs incurred in connection therewith and could incur additional
losses associated with any related contingent liabilities. The future growth of
AES is dependent, in part, upon the demand for significant amounts of additional
electrical generating capacity and its ability to obtain contracts to supply
portions of this capacity. Any material unremedied delay in, or unsatisfactory
completion of, construction of AES's projects could, under certain
circumstances, have an adverse effect on AES's ability to meet its obligations.
AES also is faced with certain development uncertainties arising out of doing
business outside of the United States. See "-- Doing Business Outside the United
States."
 
     UNCERTAINTY OF ACCESS TO CAPITAL FOR FUTURE PROJECTS
 
     Each of AES's projects under development and those independent power
facilities it may seek to acquire may require substantial capital investment.
Continued access to capital with acceptable terms is necessary to assure the
success of future projects and acquisitions. AES has substantially utilized
project financing loans to fund the capital expenditures associated with
constructing and acquiring its electric power plants and related assets. Project
financing borrowings have been substantially non-recourse to other subsidiaries
and affiliates and to AES as the parent company and are generally secured by the
capital stock, physical assets, contracts and cash flow of the related project
subsidiary or affiliate. AES intends to continue to seek, where possible, such
non-recourse project financing in connection with the assets which AES or its
affiliates may develop, construct or acquire. However, depending on market
conditions and the unique characteristics of individual projects, such financing
may not be available or AES's traditional providers of project financing,
particularly multinational commercial banks, may seek higher borrowing spreads
and increased equity contributions.
 
     Furthermore, because of the reluctance of commercial lending institutions
to provide non-recourse project financing (including financial guarantees) in
certain less developed economies, AES, in such locations, has and will continue
to seek direct or indirect (through credit support or guarantees) project
financing from a limited number of multilateral or bilateral international
financial institutions or agencies. As a precondition to making such project
financing available, these institutions may also require governmental guarantees
of certain project and sovereign related risks. Depending on the policies of
specific governments, such guarantees may not be offered and as a result, AES
may determine that sufficient financing will ultimately not be available to fund
the related project.
 
     In addition to project financing loans, if available, AES provides a
portion, or in certain instances all, of the remaining long-term financing
required to fund development, construction, or acquisition. These
 
                                       14
<PAGE>   22
 
investments have generally taken the form of equity investments or loans, which
are subordinated to the project financing loans. The funds for these investments
have been provided by cash flows from operations and by the proceeds from
borrowings under the short-term credit facilities and issuances of senior
subordinated notes, convertible debentures and AES Common Stock.
 
     AES's ability to arrange for financing on either a fully non-recourse or a
substantially non-recourse basis and the costs of such capital are dependent on
numerous factors, including general economic and capital market conditions, the
availability of bank credit, investor confidence in AES, the continued success
of current projects and provisions of tax and securities laws which are
conducive to raising capital in this manner. Should future access to capital not
be available, AES may decide not to build new plants or acquire existing
facilities. While a decision not to build new plants or acquire existing
facilities would not affect the results of operations of AES based on its
currently operating facilities or facilities under construction, such a decision
would affect the future growth of AES.
 
     CONTROL BY EXISTING STOCKHOLDERS
 
     As of February 1, 1997, AES's two founders, Roger W. Sant and Dennis W.
Bakke, and their immediate families together owned beneficially approximately
25% of AES's outstanding Common Stock. As a result of their ownership interests,
Messrs. Sant and Bakke may be able to significantly influence or exert control
over the affairs of AES, including the election of AES's directors. As of
February 1, 1997, all of AES's officers and directors and their immediate
families together owned beneficially approximately 34% of AES's outstanding
Common Stock. To the extent that they decide to vote together, these
stockholders would be able to significantly influence or control the election of
AES's directors, the management and policies of AES and any action requiring
stockholder approval, including significant corporate transactions.
 
     LITIGATION CONCERNING THE AMALGAMATION
 
     On November 22, 1996, an action was filed against AES in the Court of
Chancery of the State of Delaware in and for New Castle County, by a holder of
750 shares of AES Chigen Class A Common Stock, individually and on behalf of a
purported class of public shareholders of the approximately 8.2 million
outstanding shares of AES Chigen Class A Common Stock. The complaint seeks
preliminarily and permanently to enjoin AES from acquiring the outstanding
shares of AES Chigen which it does not already own. In addition, the complaint
seeks unspecified damages, including attorneys' fees and costs.
 
     AES Chigen is not named in the suit. Plaintiff's allegations state that
AES, as the controlling shareholder of AES Chigen, breached its fiduciary duties
to treat the plaintiff class with entire fairness in connection with AES's
execution of an agreement with AES Chigen to acquire the outstanding AES Chigen
Class A Common Stock at an allegedly grossly inadequate price.
 
     The parties have entered into a stipulation extending, until March 24,
1997, AES's time to answer, move or otherwise plead to the complaint and answer
or object to plaintiff's pending document production request. Plaintiff has the
right to move for an order requiring an earlier response. AES has informed AES
Chigen that it believes that it has meritorious defenses to the lawsuit and
intends to defend against it vigorously. The parties to the Amalgamation
Agreement intend to proceed with the Amalgamation, subject to shareholder
approval and the satisfaction of the other conditions contained in the
Amalgamation Agreement, unless enjoined.
 
     DEPENDENCE ON UTILITY CUSTOMERS AND CERTAIN PROJECTS
 
     The nature of most of AES's power projects is such that each facility
generally relies on one power sales contract with a single customer for the
majority, if not all, of its revenues over the life of the power sales contract.
During 1995, four customers, Oklahoma Gas & Electric Company (24%), The
Connecticut Light & Power Company, a subsidiary of Northeast Utilities (18%),
Hawaiian Electric Company, Inc. (18%) and Empresa Social de Energia de Buenos
Aires S.A. (13%), accounted for a total of 73% of AES's revenues. In October
1996, Moody's Investor Service and Standard & Poor's revised their ratings of
the senior unsecured long-term debt of Connecticut Light & Power Company from
Baa3/BBB- to Ba1/BB+, which
 
                                       15
<PAGE>   23
 
made The Connecticut Light & Power Company the only one of AES's U.S. customers
whose long-term debt is not investment grade. The prolonged failure of any one
utility customer to fulfill its contractual obligations could have a substantial
negative impact on AES's primary source of revenues. AES has sought to reduce
this risk in part by entering into power sales contracts with utilities or other
customers of strong credit quality and by locating its plants in different
geographic areas in order to mitigate the effects of regional economic
downturns.
 
     Four of AES's plants collectively represented approximately 61% of AES's
consolidated total assets at December 31, 1995 and generated approximately 80%
of AES's consolidated total revenues for the year ended December 31, 1995.
 
     REGULATORY UNCERTAINTY
 
     AES's cogeneration operations in the United States are subject to the
provisions of various laws and regulations, including the Public Utility
Regulatory Policies Act of 1978, as amended ("PURPA"), and the Public Utility
Holding Company Act, as amended ("PUHCA"). PURPA provides to qualifying
facilities ("QFs") certain exemptions from substantial federal and state
legislation, including regulation as public utilities. PUHCA regulates public
utility holding companies and their subsidiaries. AES is not and will not be
subject to regulation as a holding company under PUHCA as long as the domestic
power plants it owns are QFs under PURPA. QF status is conditioned on meeting
certain criteria, and would be jeopardized, for example, by the loss of a steam
customer. AES believes that, upon the occurrence of an event that would
threaten the QF status of one of its domestic plants, it would be able to react
in a manner that would avoid the loss of QF status (such as by replacing the
steam customer). In the event AES were unable to avoid the loss of such status
for one of its plants, to avoid public utility holding company status, AES
could apply to the Federal Energy Regulatory Commission ("FERC") to obtain
status as an Exempt Wholesale Generator ("EWG"), or could restructure the
ownership of the project subsidiary. EWGs, however, are subject to broader
regulation by FERC and may be subject to state public utility commission
regulation regarding non-rate matters. In addition, any restructuring of a
project subsidiary could result in, among other things, a reduced financial
interest in such subsidiary, which could result in a gain or loss on the sale
of the interest in such subsidiary, the removal of such subsidiary from the
consolidated income tax group or the consolidated financial statements of AES,
or an increase or decrease in the results of operations of AES.
 
     The United States Congress is considering proposed legislation which would
repeal PURPA entirely, or at least repeal the obligation of utilities to
purchase from QFs. There is strong support for grandfathering existing QF
contracts if such legislation is passed, and also support for requiring
utilities to conduct competitive bidding for new electric generation if the
PURPA purchase obligation is eliminated. Various bills have also proposed repeal
of PUHCA. Repeal of PUHCA would allow both independents and vertically
integrated utilities to acquire retail utilities in the United States that are
geographically widespread, as opposed to the current limitations of PUHCA which
require that retail electric systems be capable of physical integration. In
addition, registered holding companies would be free to acquire non-utility
businesses, which they may not do now, with certain limited exceptions. In the
event of a PUHCA repeal, competition for independent power generators from
vertically integrated utilities would likely increase. Repeal of PURPA and/or
PUHCA may or may not be part of comprehensive legislation to restructure the
electric utility industry, allow retail competition, and deregulate most
electric rates. The effect of any such repeal cannot be predicted, although any
such repeal could have a material adverse effect on AES.
 
     ELECTRIC UTILITY INDUSTRY RESTRUCTURING PROPOSALS
 
     The FERC and many state utility commissions are currently studying a number
of proposals to restructure the electric utility industry in the United States.
Such restructuring would permit utility customers to choose their utility
supplier in a competitive electric energy market. The FERC issued a final rule
in April 1996 which requires utilities to offer wholesale customers and
suppliers open access on utility transmission lines, on a comparable basis to
the utilities' own use of the lines. The final rule is subject to rehearing and
may become the subject of court litigation. Utilities have now filed "open
access" tariffs. The utilities contend that they should recover from departing
customers their fixed costs that will be "stranded" by the ability of their
 
                                       16
<PAGE>   24
 
wholesale customers (and perhaps eventually, their retail customers) to choose
new electric power suppliers. The FERC final rule endorses the recovery of
legitimate and verifiable "stranded costs." These may include the costs
utilities are required to pay under many QF contracts which the utilities view
as excessive when compared with current market prices. Many utilities are
therefore seeking ways to lower these contract prices or rescind the contracts
altogether, out of concern that their shareholders will be required to bear all
or part of such "stranded" costs. Some utilities have engaged in litigation
against QFs to achieve these ends.
 
     In addition, future United States electric rates may be deregulated in a
restructured United States electric utility industry and increased competition
may result in lower rates and less profit for United States electricity sellers.
Falling electricity prices and uncertainty as to the future structure of the
industry is inhibiting United States utilities from entering into long-term
power purchase contracts. The effect of any such restructuring on AES cannot be
predicted, although any such restructuring could have a material adverse effect
on AES.
 
     LITIGATION AND REGULATORY PROCEEDINGS
 
     From time to time, AES and its subsidiaries and other affiliates are
parties to litigation and regulatory proceedings. AES Chigen shareholders should
review the descriptions of such matters contained in AES's Annual, Quarterly and
Current reports filed with the Commission and incorporated by reference herein.
There can be no assurance that any such litigation or regulatory proceedings
will not have a material adverse effect on AES or its subsidiaries or
affiliates. For a description of a lawsuit recently filed against AES in respect
of the Amalgamation, see "-- Litigation Concerning the Amalgamation."
 
     BUSINESS SUBJECT TO STRINGENT ENVIRONMENTAL REGULATIONS
 
     AES's activities are subject to stringent environmental regulation by
federal, state, local and foreign governmental authorities. For example, the
Clean Air Act Amendments of 1990 impose more stringent standards than those
previously in effect, and require states to impose permit fees on certain
emissions. Congress and other foreign governmental authorities also may consider
proposals to restrict or tax certain emissions. These proposals, if adopted,
could impose additional costs on the operation of AES's power plants. There can
be no assurance that AES would be able to recover all or any increased costs
from its customers or that its business, financial condition or results of
operations would not be materially and adversely affected by future changes in
domestic or foreign environmental laws and regulations. AES has made and will
continue to make capital and other expenditures to comply with environmental
laws and regulations. There can be no assurance that such expenditures will not
have a material adverse effect on AES's financial condition or results of
operations.
 
     ADHERENCE TO AES'S PRINCIPLES -- POSSIBLE IMPACT ON RESULTS OF OPERATIONS
 
     A core part of AES's corporate culture is a commitment to "shared
principles": to act with integrity, to be fair, to have fun and to be socially
responsible. AES seeks to adhere to these principles not as a means to achieve
economic success, but because adherence is a worthwhile goal in and of itself.
However, if AES perceives a conflict between these principles and profits, AES
will try to adhere to its principles -- even though doing so might result in
diminished or foregone opportunities or financial benefits.
 
AES CHIGEN RISK FACTORS
 
     Holders of AES Chigen Class A Common Stock should carefully consider the
following factors relating to AES Chigen and the AES Chigen Class A Common Stock
in connection with their consideration of the Amalgamation. Such factors would
continue to apply to AES Chigen, as a wholly-owned subsidiary of AES, if the
Amalgamation is consummated.
 
RISKS PERTAINING TO THE PRC
 
     AES Chigen has substantially all of its assets in, and derives
substantially all of its revenues from, power plants owned by its Joint Ventures
(as defined below) located in the PRC. Therefore, AES Chigen and its
 
                                       17
<PAGE>   25
 
operations are affected generally by developments in or affecting the PRC.
"Joint Ventures" means the PRC joint venture limited liability companies formed
to develop, construct, own and operate the current projects (see "The
Companies -- Business of AES Chigen -- Description of the Current Projects")
with respect to which AES Chigen, or one of its wholly-owned subsidiaries, has
made a contribution to the registered capital (equity). A "Joint Venture" refers
to any one of the PRC joint venture limited liability companies.
 
     POLITICAL AND ECONOMIC CONSIDERATIONS
 
     General economic conditions in the PRC could have a significant impact on
the business prospects of AES Chigen. The economy of the PRC differs from the
economies of most countries belonging to the Organization for Economic
Co-operation and Development in such respects as structure, government
involvement, level of development, growth rate, capital reinvestment, allocation
of resources, self-sufficiency, rate of inflation and balance of payments
position, among others. For over 40 years, the economy of the PRC has been
primarily a planned economy characterized by state ownership and control of
productive assets and the management of such assets through a series of economic
and social development plans. Although the majority of the PRC's productive
assets are still owned by the PRC Government, the adoption of economic reform
policies since 1978 has resulted in a gradual reduction in the role of state
economic plans in the allocation of resources, pricing and management of such
assets, an increased emphasis on the utilization of market forces, and rapid
growth in the PRC economy. However, such growth has been uneven among various
regions of the country and among various sectors of the economy. The success of
AES Chigen depends in part on the continued economic growth of the regions where
the Joint Ventures are located. At times, the economic reform measures adopted
by the national government of the PRC and its various ministries, agencies and
commissions (the "Central Government") and local governments (together with the
Central Government, the "PRC Government") may be inconsistent or ineffectual,
and therefore the Joint Ventures may not be able to enjoy the potential benefits
of such reforms. Further, these measures may be adjusted or modified in
particular ways in particular areas, possibly resulting in such economic
liberalization measures being inconsistent from time to time or from industry to
industry or across different regions of the PRC.
 
     AES Chigen may also be adversely affected by changes in the political and
social conditions in the PRC, and by changes in governmental policies with
respect to laws and regulations, methods to address inflation, currency
conversion, rates and methods of taxation, or the method by which electricity
tariffs are set and approved, among other things. While the PRC Government is
expected to continue its economic reform policies, many of the reforms are new
or experimental and may be refined or changed. It is also possible that a change
in the PRC Government leadership could lead to changes in economic policy.
 
     The PRC economy has experienced rapid growth in the past five years. This
growth has also been accompanied by rising inflation, which reached an annual
rate of 21.7% in 1994. The PRC Government has implemented policies from time to
time to restrain the rate of such economic growth and control inflation in order
to achieve coordinated economic development. In July 1993, the Central
Government began implementation of a number of austerity measures to control
economic growth and curb inflation, including increasing interest rates on bank
loans and deposits and postponing certain planned price reforms. While inflation
has since moderated to 8.6% for the first ten months of 1996, there can be no
assurance that such austerity measures will not be strengthened or result in
future severe dislocations in the PRC economy. Austerity measures intended to
slow economic growth may affect the demand for electricity and the prospects for
the financing of some of the Joint Ventures. Depending on the nature and
implementation of such additional measures, the Joint Ventures' economic
prospects at times may be adversely affected through, among other possible
measures, placing additional controls on the increase of electric power rates.
Any such development could also adversely affect the Joint Ventures' operations
or the ability of the Joint Ventures' customers to honor their obligations under
their power purchase contracts, which could adversely affect AES Chigen.
 
     A significant portion of the economic activity in the PRC is related to
exports and may therefore be affected by developments in the economies of the
PRC's principal trading partners. Trade sanctions imposed by the PRC's main
trading partners, including the revocation or conditional extension by the
United States of China's Most Favored Nation trading status, could adversely
affect the trade and economic development of the PRC and the ability of the
Joint Ventures' customers to honor their obligations under their power purchase
 
                                       18
<PAGE>   26
 
contracts with the Joint Ventures. In addition, current or future disputes
between the PRC and its main trading partners over specific trade issues, such
as intellectual property, the balance of trade or other political issues, such
as regional affairs or arms sales policies, could lead to the imposition of
trade or other sanctions which could adversely affect the demand for power in
the PRC.
 
     RESTRICTIONS ON FOREIGN CURRENCY CONVERTIBILITY AND REMITTANCE ABROAD
 
     The Joint Ventures will receive nearly all of their revenues in Renminbi. A
significant portion of this revenue will need to be converted to other
currencies, primarily US dollars, and remitted outside of the PRC to meet
foreign currency obligations to equipment suppliers, to repay borrowings from
foreign third party lenders and to make payments to AES Chigen in respect of
equity distributions and shareholder loans. The Renminbi is not freely
convertible into US dollars. Although the receipt of approvals to convert
Renminbi into foreign currencies and to remit foreign currencies outside of the
PRC is routine for approved foreign investment enterprises such as the Joint
Ventures, there can be no assurance that the PRC Government will continue to
provide such approvals. Moreover, while in the last two years foreign currency
has been readily available, no assurance can be given that the Joint Ventures
will in the future be able to convert sufficient amounts of Renminbi to foreign
currency in China's foreign exchange markets to meet their foreign currency
obligations, or that the Joint Ventures will freely be able to remit foreign
currency abroad.
 
     EXCHANGE RATE FLUCTUATIONS
 
     Prior to 1994, the Renminbi had experienced a significant net devaluation
against most major currencies, and during certain periods, significant
volatility in the market-based exchange rate. Since the beginning of 1994, the
Renminbi to US dollar exchange rate has largely stabilized. While the Joint
Ventures will receive nearly all of their revenues in Renminbi, AES Chigen
expects its Joint Ventures to have significant US dollar obligations with
respect to distributions to AES Chigen. Under the terms of all of their power
purchase contracts, AES Chigen's Joint Ventures are entitled to obtain tariff
adjustments for future Renminbi devaluation. While AES Chigen expects that its
Joint Ventures will be able to pass on increased costs resulting from a
devaluation of the Renminbi by means of such tariff adjustments, no assurance
can be given that the Joint Ventures will be able to obtain approval for a
sufficient tariff adjustment.
 
     DEVELOPING LEGAL SYSTEM
 
     China's legal system is relatively new, and the government is still in the
process of developing a comprehensive system of laws, a process that has been
ongoing since 1979. Considerable progress has been made in the promulgation of
laws and regulations dealing with economic matters such as corporate
organization and governance, foreign investment, commerce, taxation and trade.
Such legislation has significantly enhanced the protection afforded to foreign
investors. However, foreign investors may be adversely affected by new laws,
changes to existing laws (or interpretations thereof) and preemption of
provincial or local regulations by national laws or regulations. Moreover,
experience with respect to the implementation, interpretation and enforcement of
such laws and regulations is limited. Such administrative and judicial
interpretation and implementation and the enforcement of commercial claims and
resolution of commercial disputes may be subject to the exercise of considerable
discretion by both administrative and judicial organs and may be influenced by
external forces unrelated to the legal merits of a particular matter or dispute.
Even where adequate laws exist and contractual terms are clearly stated, there
can be no assurance that AES Chigen or a Joint Venture will obtain swift and
equitable enforcement of its rights.
 
RISKS RELATED TO AES CHIGEN'S BUSINESS
 
     REGULATION AND RESTRICTIONS; TARIFFS
 
     Similar to electric power companies in other countries, AES Chigen's Joint
Ventures are subject to governmental and electric power regulation in virtually
all aspects of their operations, including the amount and timing of electricity
generation, the setting of electric power tariffs, performance of scheduled
maintenance and compliance with power grid control and dispatch directives.
Foreign ownership of electric power
 
                                       19
<PAGE>   27
 
plants in China is also restricted or controlled in varying degrees. There can
be no assurance that these regulations and restrictions will not change in the
future in a manner which could adversely affect the operations of AES Chigen's
Joint Ventures.
 
     For power plants with foreign investment such as AES Chigen's Joint
Ventures, tariffs payable under power purchase contracts entered into by the
Joint Ventures are established on the basis of tariff formulas which are agreed
upon after discussions among AES Chigen, its partners, the prospective power
purchasers, the relevant local governments, the relevant pricing bureaus and the
relevant planning commissions. Once established, the tariffs are subject to
annual review by the relevant local government pricing bureau and adjustment in
accordance with the formulas. The tariff formulas contained in the power
purchase contracts entered into by AES Chigen's Joint Ventures are structured to
permit the Joint Ventures to pay the operating expenses of the plant, the
financing costs of each particular project and to enable AES Chigen to realize a
return on its investment. While the relevant PRC pricing bureaus have committed
to utilize the Joint Ventures' formulas in establishing and adjusting tariffs,
there can be no assurance that the relevant pricing bureaus will calculate and
adjust tariffs in accordance with these tariff formulas. On April 1, 1996, a new
law governing the electric power sector in the PRC came into effect. The law
establishes, among other things, broad principles with respect to the
methodology of calculating and setting electric power tariffs. Detailed
regulations with respect to tariff calculation and tariff setting are expected
to be promulgated in the near future by the Central Government. There can be no
assurance that such regulations, when promulgated, will not adversely affect the
tariff structures which AES Chigen's Joint Ventures have adopted.
 
     GOVERNMENT APPROVAL PROCESSES
 
     China's electric power industry is highly regulated, both in terms of
operating existing power plants and developing new power projects. All electric
power projects in China and all foreign investments are required to obtain
approvals from one or more central, provincial or local government authorities.
While the regulations governing and the procedures for obtaining approvals for
foreign investment projects are generally well-understood, the specific
regulations and procedures for the approval of electric power projects with
foreign investment in the PRC and associated foreign investment enterprises are
not entirely transparent. Project approvals and foreign investment approvals are
required, but follow separate procedures. At the highest level, the right to
approve projects in the PRC is vested in the State Council. The State Council
has reserved to itself the authority to approve any project with a total
investment which exceeds $100 million. Pursuant to various internal PRC
Government notices, the State Council has delegated the authority to approve any
project with a total investment of less than $100 million to various ministries
and ministry level entities, including the State Planning Commission of the
Central Government (the "SPC"). The SPC and certain ministries and other
ministry level entities have, in turn, adopted a policy, also by internal
directives, of further delegating authority to approve projects with a total
investment of less than $30 million to provincial governments, provincial level
bureaus of the Central Government and certain municipalities. The project
approval authority of local governments is, therefore, generally limited to not
more than $30 million. Separate from project approval, foreign investment must
be approved by the Ministry of Foreign Trade and Economic Cooperation
("MOFTEC"), or one of its departments at the provincial or local government
level, should the total investment amount be below $30 million. Accordingly,
foreign investment enterprises proposing to undertake projects must obtain
approvals for the projects from the appropriate government level planning
authorities and approvals for the foreign investment from a similar level
department of MOFTEC.
 
     Two of AES Chigen's power plants have been structured as multiple projects
and joint ventures, each project and joint venture with a total investment below
the $30 million threshold, and have obtained local government approvals on this
basis. It is possible that projects structured in this fashion could be viewed
by the Central Government approval authorities as a single project. In several
other cases, AES Chigen's projects and Joint Ventures have obtained local
government approvals on the basis of anticipated total investments which were
less than $30 million at the time the approvals were obtained, but will, when
construction is completed, exceed the $30 million approval threshold. While it
is common in the PRC for projects and joint ventures such as these to obtain and
rely on only local government approvals, it is unclear whether such approvals
are
 
                                       20
<PAGE>   28
 
sufficient. There can be no assurance, therefore, that the absence of Central
Government approvals will not adversely affect the Joint Ventures and their
projects in any of such cases.
 
     ENVIRONMENTAL MATTERS
 
     AES Chigen's Joint Ventures with power plants in operation have received
the environmental approvals from the PRC Government environmental authorities
required for them to operate their respective electric power plants. Inasmuch as
the Joint Ventures' electric power plants currently under construction are
typically among the most modern in the areas in which they are located, AES
Chigen believes that these plants will also receive all required environmental
approvals. There can be no assurance, however, that the requirements to obtain
such approvals may not be made more stringent in the future. If such a change in
policy occurs, there can be no assurance that all such requirements will be met
and that future approvals for existing or potential projects will be granted. If
a change in environmental requirements leads to an increase in costs, an
affected Joint Venture is able to receive an adjustment in the tariff it charges
for electric power pursuant to its power purchase contract.
 
     The PRC is a party to the Framework Convention on Climate Change ("Climate
Change Convention"), which is intended to limit or capture emissions of
"greenhouse" gases, such as carbon dioxide. At present, ceilings on such
emissions could limit the production of electricity from fossil fuels,
particularly coal, or increase the costs of such production. At present,
ceilings on the emissions of "greenhouse" gases have not been assigned to
developing countries such as the PRC under the Climate Change Convention, and
the PRC has objected to any imposition of such ceilings. If the PRC were to
agree to such ceilings, or otherwise reduce its reliance on coal-fired power
plants, the business prospects of AES Chigen could be adversely affected.
 
     CONSTRUCTION RISKS
 
     The construction of an electric power generation plant, including its
ancillary facilities such as a transmission line or substation, may be adversely
affected by many factors commonly associated with the construction of
infrastructure projects, including shortages of equipment, materials and labor,
as well as labor disputes, adverse weather conditions, natural disasters,
accidents and other unforeseen circumstances and problems. Any of these could
cause completion delays and cost overruns. Delays in obtaining requisite
licenses, permits or approvals from government agencies or authorities could
also increase the cost or delay or prevent the commercial operation of a
project. Construction delays can result in the loss or delayed receipt of
revenues and, if completion is delayed beyond the completion date specified in
the power purchase contract, the payment of penalties. Additionally, the failure
to complete construction according to specifications can result in reduced plant
efficiency, higher operating costs and reduced or delayed earnings.
 
     AES Chigen's Joint Ventures all rely on PRC contractors for the
construction of their electric power plants. While there are a number of PRC
contractors with substantial construction experience, there are only a limited
number that have experience constructing plants on a turnkey basis. In only a
few cases has AES Chigen been able to enter into a turnkey contract with a
Chinese contractor which includes a guaranteed fixed price and/or contractor
obligations to pay liquidated damages for delays in completion or for shortfalls
in performance. In the case of one project, AES Chigen's Joint Venture has
experienced delays in installation and defects in the quality of equipment. The
delays have been mitigated by the payment of damages by the contractor. AES
Chigen seeks to mitigate construction risk in a number of ways: carefully
choosing its contractors; closely supervising the construction of its projects
or retaining internationally recognized construction managers to supervise
construction; and, in some cases, by utilizing established foreign equipment
manufacturers and vendors who are able to directly pass through to the Joint
Ventures their equipment and performance warranties or, where appropriate, by
utilizing proven Chinese equipment and technology. Despite such mitigation
efforts, no assurance can be given that AES Chigen's Joint Ventures will not
experience construction delays or difficulties, or that any such delays or
difficulties will not have a material adverse effect on the operations of AES
Chigen's Joint Ventures.
 
                                       21
<PAGE>   29
 
     OPERATING RISKS
 
     The operation of an electric power generation plant may be adversely
affected by many factors such as the breakdown or failure of equipment or
processes, performance below expected levels of output or efficiency, labor
disputes, operational errors, natural disasters, and the need to comply with the
directions of the relevant government authorities, the dispatcher and power
purchaser of a power plant. In addition, such operation may be hampered by
insufficient or poor quality fuel caused by either inadequate supply or
transportation or arrangements therefor.
 
     AES Chigen is not the operator of any of its power plants either directly
or by means of traditional operation and maintenance agreements with
internationally recognized power plant operators. In some cases, AES Chigen's
Joint Ventures have contracted with the power purchaser to operate a power
plant. In such instances, the power purchaser is obligated under the power
purchase contract to purchase the annual minimum quantity of electric power
regardless of the power plant being unavailable due to the fault of the
operator. In other cases, the Joint Ventures themselves are operating the plant.
In these instances, AES Chigen may affect the operation of a power plant through
the appointment of a general manager and/or deputy general manager of the plant.
 
     FUEL RISKS
 
     Most of the Joint Ventures' power projects utilize coal, fuel oils or
natural gas for the generation of electricity. The power purchase contracts
which have been entered into by the Joint Ventures provide for a pass-through to
the power purchasers of increases in the cost of fuel. In the case of most of
the Joint Ventures, under normal circumstances, the procedures of the local
government pricing bureaus allow tariff adjustments reflecting fuel cost changes
to be made only once a year. As a result, in these cases AES Chigen's Joint
Ventures may not be able to receive compensation for increased fuel costs until
sometime after the date they are incurred.
 
     For coal projects which are not "mine mouth" projects, coal must be
supplied to the project site from the interior provinces of China. The affected
Joint Ventures seek to mitigate this transportation risk by entering into long
term contracts for the transportation of coal. However, where rail is utilized
as the means of coal transportation, the coal transporters may experience
significant delays due to the limited capacity of the PRC's rail system. Because
of this lack of capacity, the Central Government rations the allocation of rail
cars. In one project which requires the transportation of coal by rail, AES
Chigen's Joint Venture has obtained an administrative allocation of rail cars
from the Central Government. However, there can be no assurance that a
satisfactory allocation of rail cars will be available in all future cases to
ensure that the coal supply requirements of the affected projects will be timely
met.
 
     LOAD GROWTH; DISPATCH; TRANSMISSION CONSTRAINTS
 
     Some regions or cities in the PRC have experienced slower economic
development in recent years. As a consequence, load growth in the PRC, while
generally increasing in the country overall, has exhibited uneven development.
Some of the Joint Ventures' power plants are designed to provide peaking power.
Such plants are dispatched only after base load power stations have been brought
on-line and reached maximum capacity. If electric power demand proves less than
expected in an area, additional peak or base load power may not be required in
the area or may be required at lower than expected levels. AES Chigen's Joint
Ventures seek to mitigate this risk by entering into take-or-pay power purchase
arrangements and by entering into dispatch contracts with PRC electric power
dispatching authorities which obligate the dispatchers to dispatch the power
plants at their full capacity for a minimum number of hours each year. There can
be no assurance, however, that the Joint Ventures will not experience difficulty
in enforcing take or pay contract obligations or such dispatch contract
obligations if electric power in an area proves not to be needed by the affected
power purchaser and dispatcher.
 
     Additionally, the Chinese electric power transmission system is not fully
interconnected. Some parts of the transmission system contain isolated grids.
Three of AES Chigen's Joint Ventures are located in areas served by isolated
transmission grids. As a result, if demand in these areas is less than forecast,
it may be
 
                                       22
<PAGE>   30
 
difficult or impossible for the affected Joint Venture to transmit the project's
available power to a region which has a demand for it. In order to take
advantage of a broader market and an additional power purchaser, one of these
Joint Ventures is planning to incur additional costs to build a low-voltage
local transmission line to interconnect its power plant with a larger grid.
 
     RELIANCE ON AND CREDITWORTHINESS OF PRC COUNTERPARTIES
 
     In all of its projects, AES Chigen and its Joint Ventures are relying on
the reliability and creditworthiness of PRC entities such as its partners,
contractors, customers, suppliers, operators, guarantors, lenders and others who
are parties to agreements with AES Chigen or its Joint Ventures. While AES
Chigen believes that these counterparties have the ability to perform and will
perform their obligations, the reliability and creditworthiness of PRC entities
are difficult to ascertain. In most cases, AES Chigen, in assessing the
reliability and credit standing of counterparties, is relying on financial or
other information provided to AES Chigen or its Joint Ventures by such parties
or others, or from information and sources publicly available in the PRC. AES
Chigen can offer no assurance that this information is accurate or that these
counterparties will meet their contractual obligations. The failure of any one
of these counterparties to fulfill its obligations to a Joint Venture could have
a substantial negative impact on such Joint Venture's operations.
 
     CONFLICTS OF INTEREST OF CONTRACTING PARTIES
 
     In a number of cases, AES Chigen's partner in a Joint Venture controls or
is affiliated with the power purchaser, contractor, operator and/or fuel
supplier of the project. It is possible, in these cases, that such arrangements
may result in one or more of these parties having a conflict of interest in a
project, which could have an adverse effect on the Joint Ventures' operations.
 
     CONTROL BY AND RELIANCE ON AES
 
     AES currently holds all of the outstanding shares of AES Chigen's Class B
Common Stock and is entitled, voting as a class, to elect one-half of the Board
of Directors of AES Chigen. Most of AES Chigen's executive officers are also
senior executives, officers and project personnel employed by AES. As a result,
AES and its officers and directors have a significant day-to-day influence over
the operations of AES Chigen.
 
     ADHERENCE TO THE AES PRINCIPLES
 
     A core part of AES's corporate culture is a commitment to "shared
principles": to act with integrity, to be fair, to have fun and to be socially
responsible. AES Chigen has adopted a similar corporate culture and tries to
adhere to these principles, like AES, not as a means to achieve economic
success, but because adherence is a worthwhile goal in and of itself. However,
if AES Chigen or AES perceives a conflict between these principles and profits,
AES Chigen and AES will try to adhere to these principles -- even though doing
so might result in diminished or foregone opportunities.
 
                  THE CLASS A MEETING AND THE SPECIAL MEETING
 
     The accompanying proxy is solicited by the Board of Directors of AES Chigen
for use at the Special Class Meeting of the holders of the AES Chigen Class A
Common Stock and at the Special General Meeting of Shareholders of AES Chigen to
be held on March 31, 1997 at 1001 North 19th Street, Arlington, Virginia 22209,
or at any adjournment of such meetings. This Proxy Statement/Prospectus and
accompanying proxy are first being sent or given to shareholders on or about
March   , 1997.
 
     Only holders of AES Chigen Class A Common Stock at the close of business on

outstanding AES Chigen Class B Common Stock and has agreed in the Amalgamation
Agreement to vote such shares in favor of adoption and approval of the
Amalgamation Agreement. AES will vote such shares by means of a written consent
in lieu of a special meeting of the Class B shareholders and will vote such
shares in favor of adoption and approval of the Amalgamation Agreement and the
Amalgamation at the Special Meeting.
 
     If a proxy is properly executed and returned to AES Chigen, the shares it
represents will be voted at the meetings in accordance with the instructions
noted thereon. If no instructions are specified, the shares will be voted in
accordance with the Board of Directors' recommendations as set forth herein and
will confer authority to vote to adjourn the meetings for up to thirty days to
solicit additional votes if necessary to approve and adopt the Amalgamation
Agreement. Any shareholder executing a proxy has the power to revoke it at any
time before it is voted by filing with AES Chigen a written notice of
revocation, by delivering a duly executed proxy bearing a later date, or by
attending the Class A Meeting and/or the Special Meeting and voting in person.
 
     The approval of the Amalgamation Agreement by the shareholders of AES
Chigen will require (x) the affirmative vote of the holders of a majority of the
outstanding shares of AES Chigen Class A Common Stock and the AES Chigen Class B
Common Stock, each voting as a separate class at a separate meeting or by
written consent and (y) the affirmative votes of a majority of the votes cast at
the Special Meeting. For the Class A Meeting, approval of the Amalgamation
Proposal will require the affirmative vote of the holders of no less than
4,085,635 shares of AES Chigen Class A Common Stock. In lieu of a special
meeting of the Class B shareholders, AES, the holder of all the outstanding AES
Chigen Class B Common Stock, has agreed in the Amalgamation Agreement to vote
its shares in favor of the Amalgamation Proposal by means of a written consent.
 
     As of February 1, 1997, the directors and executive officers of AES and AES
Chigen owned an aggregate of 9,100 shares (or less than 1%) of AES Chigen Class
A Common Stock entitled to vote at the Class A Meeting and the Special Meeting.
All directors and executive officers of AES and AES Chigen entitled to vote
intend to vote their shares in favor of the Amalgamation.
 
     For the Class A Meeting, a quorum consists of a minimum of two shareholders
present in person or by proxy and representing in excess of 50% of the total
issued shares of AES Chigen Class A Common Stock. For the Special Meeting, a
quorum consists of a minimum of two shareholders present in person or by proxy
and representing in excess of 50% of the total issued shares of AES Chigen
Common Stock. With respect to the vote of the holders of AES Chigen Class A
Common Stock at the Class A Meeting, proxies marked as abstentions and broker
non-votes (where a nominee holding shares for a beneficial owner has not
received voting instructions from the beneficial owner with respect to a
particular matter and such nominee does not possess or choose to exercise his
discretionary authority with respect thereto) will be considered as present at
the Class A Meeting and would have the same effect as a vote against the
Amalgamation Proposal. With respect to the vote of the shareholders at the
Special Meeting, proxies marked as abstentions and broker non-votes will be
considered as present at the Special Meeting but will not be counted in
calculating the number of votes cast on the Amalgamation Proposal and therefore
will have no effect on the outcome of the votes.
 
     Proxies will be solicited by mail, telephone or other means of
communication. AES Chigen has retained the services of Corporate Investor
Communications, Inc. to assist in the solicitation of proxies from shareholders
for a fee, including their expenses, estimated at $3,750. In addition,
solicitation may be made by directors, officers, and regular employees of AES
Chigen. AES Chigen will reimburse brokerage firms, custodians, nominees and
fiduciaries in accordance with the rules of the National Association of
Securities Dealers, Inc., for reasonable expenses incurred by them in forwarding
materials to the beneficial owners of shares. The entire cost of solicitation
will be borne by AES Chigen.
 
     SHAREHOLDERS SHOULD NOT SEND SHARE CERTIFICATES WITH THEIR PROXY CARDS. THE
PROCEDURE FOR THE EXCHANGE OF SHARES AFTER THE AMALGAMATION IS CONSUMMATED IS
SET FORTH ELSEWHERE IN THIS PROXY STATEMENT/PROSPECTUS. SEE "THE
AMALGAMATION -- PROCEDURES FOR CONVERTING AES CHIGEN CLASS A COMMON STOCK INTO
AES COMMON STOCK."

                                THE AMALGAMATION
 
BACKGROUND
 
     The Board of Directors of AES Chigen held a meeting on August 1, 1996. Such
meeting included a discussion of the future financing needs for AES Chigen.
During that discussion, Dennis W. Bakke, a Class B Director of AES Chigen and
the President, Chief Executive Officer and a Director of AES, raised his general
concern (without elaboration) that the current AES Chigen ownership structure
did not allow AES Chigen to utilize, in the most effective manner, AES's
organizational resources as was originally contemplated prior to AES Chigen's
initial public offering. Mr. Bakke raised the question of whether AES should
consider the possibility of acquiring the outstanding shares of AES Chigen Class
A Common Stock presently held by the public. The Class A Directors acknowledged
concern over the issues discussed by Mr. Bakke and expressed their desire to
explore a possible transaction with AES, assuming a transaction could be
structured on acceptable terms. Mr. Bakke stated he would review the situation
internally at AES, and would provide more information to the Class A Directors
at a later point. At this time Mr. Bakke, on behalf of all of the Class B
Directors, indicated that in order to avoid any real or perceived conflict of
interest, in any future discussions between AES and AES Chigen, the Class A
Directors would have sole decision-making authority on behalf of AES Chigen on
this matter. Also, the Class B Directors indicated that they would recuse
themselves from representing AES Chigen in such discussions. In addition, it was
noted that the Stock Purchase and Shareholder's Agreement dated as of December
29, 1993 between AES and AES Chigen (the "Stock Purchase and Shareholder's
Agreement") required the agreement of the Class A Directors, voting separately,
to any transaction pursuant to which AES would acquire any shares of the AES
Chigen Class A Common Stock.
 
     In mid-August 1996, Mr. Bakke telephoned William H. Taft, IV, a Class A
Director of AES Chigen and the principal liaison between AES and the Class A
Directors, and addressed additional concerns relating to AES Chigen's existing
capital structure, including the desire to reduce AES Chigen's administrative
and operating costs, the limitations and constraints created by the pressure on
AES Chigen, as a public company, to focus on short-term results, and the
additional limitations imposed on AES Chigen as a public company focused
exclusively on the China market. Mr. Bakke indicated that AES would like to
proceed with the exploration of a possible combination of the companies,
assuming that such a transaction would be acceptable to the Class A Directors.
Mr. Bakke stated that AES felt that a stock-for-stock transaction would be the
most appropriate transaction structure, so as to provide existing AES Chigen
shareholders, as shareholders of AES, with a continuing interest in AES Chigen's
business. Mr. Bakke suggested an exchange ratio of 0.26 of a share of AES Common
Stock for each share of AES Chigen Class A Common Stock. Mr. Bakke and Mr. Taft
also discussed the steps which would be necessary for AES Chigen to be in a
position to consider the terms of any such transaction and pursue these
discussions, including the creation of a special committee of the Board of
Directors of AES Chigen and the retention by the special committee of financial
and legal advisors.
 
     On August 31, 1996, Mr. Bakke informed Mr. Taft, through Paul T. Hanrahan,
President and Chief Executive Officer of AES Chigen, that AES would be willing
to revise the terms upon which AES would acquire the shares of AES Chigen Class
A Common Stock. Under the revised terms, AES would offer to exchange shares of
AES Common Stock for shares of AES Chigen Class A Common Stock at a 0.29
exchange ratio, provided that such exchange ratio would be adjusted, if
necessary, so that a maximum of $10.88 in value of AES Common Stock would be
issued for each share of AES Chigen Class A Common Stock so exchanged. The
revised terms also contemplated that AES Chigen would agree to pay AES a
customary break-up fee in the event that the transaction was not consummated due
to the intervention of a third party. Mr. Bakke requested a reply prior to 6:00
p.m. on September 10, 1996.
 
     The Class A Directors met on September 5, 1996 by teleconference to
consider the appropriate response to the terms presented by AES. The Class A
Directors determined that, while they would be willing to consider a proposal
from AES under appropriate circumstances, they were not prepared at that time to
do so, given the terms of the offer and the short deadline for a response. The
Class A Directors determined that it was premature to consider the offer by AES
because the Class A Directors had not retained, and not received the advice of,
financial and legal advisors. The Class A Directors felt that the retention of
appropriate advisors
 
                                       25
<PAGE>   33
 
was important to ensure a process and a transaction that served the best
interests of all concerned. On September 9, 1996, Mr. Taft sent a letter to AES
setting forth the response of the Class A Directors, indicating that, because
the Class A Directors and the senior officers of AES Chigen were also occupied
with preparing for a debt offering, it would be difficult at that time to
consider the proposed transaction.
 
     In mid-September, Mr. Bakke and Mr. Taft had a meeting at the offices of
AES in Arlington, Virginia to discuss Mr. Taft's letter of September 9th.
 
     On September 24, 1996, a meeting was held at AES's offices among Mr. Bakke,
Mr. Taft, William Dykes (a Class A Director of AES Chigen) and Thomas I.
Unterberg (a director of AES and also a Class B Director of AES Chigen) in
person, and Dr. Victor Hao Li (a Class A Director of AES Chigen) participating
by teleconference. At this meeting, Mr. Bakke indicated that AES would be
interested, should the Class A Directors so desire, in making a proposal to
acquire the AES Chigen Class A Common Stock in exchange for AES Common Stock at
a 0.29 exchange ratio, provided that such exchange ratio would be adjusted, if
necessary, so that a maximum of $12.18 in value of AES Common Stock would be
issued in exchange for each share of AES Chigen Class A Common Stock. The
increase from $10.88 to $12.18 in value of AES Common Stock per share of AES
Chigen Class A Common Stock was a result of recent increases in the per share
price of AES Common Stock. Pursuant to the terms of this proposal, there would
have been no assurances provided as to the minimum value to be received by
holders of AES Chigen Class A Common Stock.
 
     In light of AES's having indicated an interest in pursuing a possible
transaction, on October 13, 1996, the AES Chigen Board of Directors formed the
Special Committee, consisting exclusively of the Class A Directors, to evaluate
the terms of any such transaction. On October 15, 1996, the Special Committee
retained Merrill Lynch to act as its financial advisor. Skadden, Arps, Slate,
Meagher & Flom LLP, which had previously been retained by AES Chigen to assist
with respect to certain potential financing transactions, was also formally
retained by the Special Committee.
 
     On October 18, 1996, counsel to AES delivered to counsel to the Special
Committee a draft agreement which could be used to provide for the amalgamation
of a wholly-owned subsidiary of AES with and into AES Chigen in the event that
AES and AES Chigen had determined to proceed with a business combination
transaction. During the next several weeks, counsel for the Special Committee
reviewed the terms of the draft agreement with counsel for AES.
 
     On November 5, 1996, Mr. Taft met with Mr. Bakke, Barry J. Sharp, the Chief
Financial Officer of AES, William R. Luraschi, the General Counsel of AES, and
Roger Naill, a Vice President of AES. Mr. Taft informed AES that the Special
Committee would be meeting the following day with its legal and financial
advisors to consider the terms as then presently proposed, and reviewed
generally with AES a tentative schedule for discussing the reactions of the
Special Committee and, if appropriate, negotiating the terms of a possible
business combination.
 
     On November 6, 1996, the Special Committee met to consider the terms of a
possible transaction, as then presently proposed by AES. The Special Committee
received a presentation from its legal advisors regarding the duties of
directors in considering such a transaction. The legal advisors, as part of
their presentation, also reviewed the terms of the agreement as proposed by AES.
The Special Committee then received a preliminary presentation from Merrill
Lynch regarding the financial terms of the transaction. After discussion and
further consultation with its financial and legal advisors, the Special
Committee determined to request that the exchange ratio be increased to 0.31 in
an effort to increase the value of the consideration to be received by the
holders of AES Chigen Class A Common Stock. In selecting 0.31, the Special
Committee noted that based on the $45 5/8 closing price of a share of AES Common
Stock on November 5, 1996, the value of the fraction of a share of AES Common
Stock to be received by holders of AES Chigen Class A Common Stock would be
$14.14, as compared to $13.23 at a 0.29 exchange ratio. The Special Committee
instructed Mr. Taft to communicate such request to AES.
 
     Later that day, Mr. Taft, together with representatives of Merrill Lynch
and Skadden, Arps, Slate, Meagher & Flom LLP, met at the offices of AES with Mr.
Bakke, Mr. Sharp, Mr. Luraschi, and Kenneth R.
 
                                       26
<PAGE>   34
 
Woodcock, a Senior Vice President of AES, to discuss the Special Committee's
response to the terms proposed by AES. Mr. Taft reviewed the work performed by
the Special Committee, as well as the analyses presented by its financial
advisor, and stated that the Special Committee felt that a minimum value for the
shares which AES Chigen shareholders would receive must be included (if a
maximum value were to be included) and that an exchange ratio of 0.31 would be
more appropriate. Mr. Taft also indicated that the Special Committee did not
feel that the inclusion of a break-up fee as part of any agreement would be
appropriate.
 
     Mr. Bakke agreed to increase the maximum value and establish a minimum
value that AES Chigen shareholders would receive, although Mr. Bakke responded
that AES would not agree to any increase in the exchange ratio. Mr. Bakke
indicated that recent increases in the market price of the AES Common Stock had
significantly increased the value of the AES Common Stock to be received by the
holders of AES Chigen Class A Common Stock. Mr. Bakke stated that continued
increases in the value of the AES Common Stock would result in a further
increase in value to the holders of AES Chigen Class A Common Stock.
 
     On November 8, 1996, representatives of Merrill Lynch, the Special
Committee's financial advisor, discussed with Mr. Sharp the possibility of
structuring a transaction at the 0.29 exchange ratio, but with a higher minimum
value to be received by holders of AES Chigen Class A Common Stock. Following
these discussions, Mr. Taft telephoned Mr. Bakke to discuss the possibility of a
transaction at an exchange ratio of 0.29 of a share of AES Common Stock for each
share of AES Chigen Class A Common Stock within a certain price range of AES
Common Stock, but which provided that the fraction of a share of AES Common
Stock to be received by the holders of AES Chigen Class A Common Stock, should
the price of AES Common Stock move outside that range, would have a value of not
less than $13.05. The $13.05 minimum value was selected as being generally
reflective of market conditions at the time for AES Chigen Class A Common Stock
(including the trading range of the AES Chigen Class A Common Stock of $9 1/4 to
$13 3/4 between October 1, 1996 and November 7, 1996), and was the minimum value
at which the financial advisor of the Special Committee had informally advised
the Special Committee that it could deliver an appropriate opinion in a
transaction with a fixed exchange ratio of 0.29. Mr. Bakke responded that he
would be prepared to support a guarantee of a minimum value, but he felt that
there should also be protection for AES should the price of a share of AES
Common Stock rise significantly. During the discussions, Messrs. Taft and Bakke
tentatively agreed that the value should be in the range of $13.05 to $14.50 and
that the proposed amalgamation agreement should provide for reimbursement of
expenses only and should not provide for a break-up fee.
 
     After Mr. Bakke indicated that he would be prepared to recommend such a
transaction to the AES Board of Directors, Mr. Taft informed Mr. Bakke that he
would instruct the Special Committee's legal counsel to contact legal counsel
for AES so as to finalize the terms of a proposed amalgamation agreement and
that, subject to obtaining a positive reaction from a majority of the other
members of the Special Committee, a meeting of the Special Committee would be
called for November 12, 1996 in Beijing to consider the revised terms.
 
     During the early evening on November 11, 1996, the Board of Directors of
AES met telephonically to consider the proposed transaction. Following
discussion, the AES Board of Directors determined to approve the proposed
transaction.
 
     At about the same time in Beijing (where because of the difference in time
zones it was early morning on November 12, 1996), the Special Committee (with
Mr. Xiliang Feng absent) met with its legal and financial advisors to consider
the proposed transaction. The Special Committee's legal advisors provided a
description of the terms of the proposed agreement and reviewed changes to the
draft agreement previously reviewed by the Special Committee. Merrill Lynch then
delivered a presentation, described under "The Amalgamation -- Opinion of the
Special Committee's Financial Advisor" regarding the financial terms of the
proposed amalgamation. The Special Committee then received the oral opinion of
Merrill Lynch, which was subsequently confirmed in a written opinion dated as of
November 12, 1996, a copy of which is attached as Appendix B hereto, see "The
Amalgamation -- Opinion of the Special Committee's Financial Advisor", to the
effect that, as of such date, the consideration to be received by holders of AES
Chigen Class A Common
 
                                       27
<PAGE>   35
 
Stock is fair to such holders from a financial point of view. After further
discussion, the Special Committee, by the unanimous vote of those members
present, resolved to recommend to the AES Chigen Board of Directors that the
Board approve the amalgamation agreement (as approved on November 12, 1996, the
"Original Amalgamation Agreement") and the transactions contemplated thereby and
recommend to the holders of AES Chigen Class A Common Stock that they approve
the Original Amalgamation Agreement and the transactions contemplated thereby.
 
     Immediately following the meeting of the Special Committee, the Board of
Directors of AES Chigen met to consider the proposed transaction. The AES Chigen
Board of Directors received a report from the Special Committee discussing the
history of the negotiations, as well as the recommendation of the Special
Committee described above. The AES Chigen Board of Directors then, by the
unanimous vote of those directors present, approved the Original Amalgamation
Agreement and the transactions contemplated thereby.
 
     On January 23, 1997, Mr. Luraschi spoke to Mr. Taft and advised him of
AES's decision to remove the $14.50 per share limit on the maximum value to be
received by holders of AES Chigen Class A Common Stock by removing the
possibility of a downward adjustment to the 0.29 exchange ratio in the event
that the price for AES Common Stock were to trade above $50 per share during the
measuring period set forth in the Original Amalgamation Agreement, subject to
the approval of the Board of Directors of AES. Mr. Taft indicated that the
revised terms would be acceptable to the Special Committee because holders of
AES Chigen Class A Common Stock would only benefit by the proposed revised
terms.
 
     On January 30, 1997, the Board of Directors of AES met and approved the
removal of the $14.50 per share cap on the exchange ratio and approved and
adopted the Amalgamation Agreement (as revised from the Original Amalgamation
Agreement).
 
     On February 12, 1997, the Special Committee met telephonically to consider
certain revisions to the terms of the Amalgamation, including removal of the
$14.50 per share cap on the value to be received by holders of AES Chigen Class
A Common Stock, as embodied in the Amalgamation Agreement, as so revised.
Following discussion, the Special Committee determined to approve the revised
terms of the AES offer and the revised Amalgamation Agreement, and to recommend
to the AES Chigen Board of Directors that the Board approve the revised
Amalgamation Agreement.
 
     Immediately following the meeting of the Special Committee, the Board of
Directors of AES Chigen met telephonically to consider the proposed revisions to
the terms of the Amalgamation. The AES Chigen Board of Directors received the
recommendation of the Special Committee described above. The AES Chigen Board of
Directors then, by unanimous vote of those directors present, approved the
revised Amalgamation Agreement.
 
REASONS FOR THE AMALGAMATION
 
     The Board of Directors of AES approved the Amalgamation because the Board
believes it will enhance the potential for future development and financing of
power projects in the PRC by AES, through AES Chigen or other subsidiaries or
affiliates of AES. The Amalgamation will allow AES Chigen, or any other
subsidiary or affiliate of AES pursuing business opportunities in the China
power market, to (i) direct its business strategy more appropriately toward
sustainable long-term performance, with less emphasis paid to short-term
earnings performance, (ii) reduce administrative and operating costs, (iii)
enhance AES Chigen's business performance through utilization of greater
resources available to the combined companies, and (iv) use AES Common Stock as
part of its compensation program to attract and retain qualified people at AES
Chigen.
 
     In addition, the Board of AES believes the Amalgamation will significantly
improve the liquidity for AES Chigen shareholders arising from low trading
volumes in AES Chigen Class A Common Stock, while reducing the share price
volatility associated with operating AES Chigen as a public company focused
solely on a developing market such as the PRC.
 
                                       28
<PAGE>   36
 
     The Amalgamation will allow AES Chigen's shareholders to continue to share
in a portion of the potential long-term gains in AES Chigen through the
ownership of AES Common Stock following the Amalgamation, while diversifying
their investment through ownership of common stock of AES, which invests in a
variety of countries, and which has a more mature business.
 
TERMS OF THE AMALGAMATION
 
     At the Effective Time, and upon the terms and subject to the conditions set
forth in the Amalgamation Agreement, AES Sub will be amalgamated with and into
AES Chigen in accordance with the Companies Act. At and after the Effective
Time, AES Chigen will continue in the form of the Amalgamated Company and will
operate under the name AES China Generating Co. Ltd.
 
     EXCHANGE RATIO.  As of the Effective Time, by virtue of the Amalgamation
and without any action on the part of the holder of any shares of AES Chigen
Class A Common Stock, each issued and outstanding share of AES Chigen Class A
Common Stock shall be canceled in consideration of the right to receive AES
Common Stock in the ratio of (i) 0.2900 of a share of AES Common Stock;
provided, that should the average closing price of AES Common Stock on the NYSE
(with fractions expressed as a decimal rounded to the nearest one
ten-thousandth) over the 15 consecutive trading day period ending at the close
of trading on the third trading day immediately prior to the date of the Special
Meeting (the "Average Closing Price") be less than $45.00, shares of AES Chigen
Class A Common Stock will be canceled in consideration of the right to receive a
fraction of a share of AES Common Stock (expressed as a decimal rounded to the
nearest one ten-thousandth) as is determined by dividing $13.05 by the Average
Closing Price (the "Exchange Ratio" or the "Amalgamation Consideration"). AES
has the right not to consummate the Amalgamation if the Exchange Ratio, as so
determined, is greater than 0.3100. Fractional shares of AES Common Stock will
not be issuable in connection with the Amalgamation. AES Chigen shareholders
will receive cash, without interest, in lieu of fractional shares of AES Common
Stock.
 
     The Exchange Ratio, the $13.05 and $45.00 floor amounts, and the maximum
exchange ratio set forth as a condition to AES's obligations will be adjusted to
reflect fully the effect of any stock split (including a consolidation) of AES
Common Stock or a dividend payable in AES Common Stock, or any other
distribution of securities or dividend (in cash or otherwise) to holders of AES
Common Stock (including, without limitation, such a distribution made in
connection with a recapitalization, reclassification, merger, consolidation,
reorganization or similar transaction, but excluding any regular quarterly
dividend paid in cash) occurring or having a record date after the date of the
Amalgamation Agreement and prior to the Effective Time.
 
     As of the Effective Time, by virtue of the Amalgamation and without any
action on the part of the holders of any shares of AES Chigen Common Stock, or
any shares of AES Sub, each share of the capital stock of AES Sub issued and
outstanding immediately prior to the Effective Time shall be converted into and
become one fully paid and nonassessable share of common stock of the Amalgamated
Company; and each share of AES Chigen Common Stock that is owned by any
subsidiary of AES Chigen and each share of AES Chigen Common Stock that is owned
by AES, AES Sub or any other subsidiary of AES shall automatically be canceled
and shall cease to exist, and no consideration shall be delivered in exchange
therefor.
 
     EFFECTIVE TIME OF AMALGAMATION; CLOSING DATE.  The Amalgamation shall
become effective at such time as a certificate of amalgamation (the "Certificate
of Amalgamation") is duly issued by the Bermuda Registrar of Companies (the time
the Amalgamation becomes effective being the "Effective Time"). The closing of
the Amalgamation will take place at 10:00 a.m. on a date to be specified by AES
or AES Sub, which may be on, but shall be no later than the third business day
after, the day on which there shall have been satisfaction or waiver of the
conditions as described under "Description of the Amalgamation
Agreement -- Conditions" below (the "Closing Date"), unless another date is
agreed to in writing by the parties to the Amalgamation Agreement.

RECOMMENDATIONS OF THE BOARDS OF DIRECTORS
 
     AES Chigen Special Committee and Board of Directors.
 
     At a meeting of the Special Committee held on November 12, 1996, the
Special Committee unanimously (with one member absent) determined (i) to approve
and adopt the Original Amalgamation Agreement in substantially the form
presented at the meeting, (ii) to approve the transactions contemplated thereby,
including the Amalgamation, and (iii) to recommend to the holders of AES Chigen
Class A Common Stock that they approve the Original Amalgamation Agreement and
the transactions contemplated thereby.
 
     In reaching the determination described above, the Special Committee gave
careful consideration, without assigning relative weights thereto, to a number
of factors, including, without limitation, the following:
 
     (1) the Special Committee's familiarity with AES Chigen's business, assets,
         financial condition, results of operations, business strategy and
         prospects, and current trends in the markets in which it operates;
 
     (2) the value and type of the consideration to be received by AES Chigen's
         shareholders;
 
     (3) the oral opinion of Merrill Lynch delivered to the Special Committee at
         the meeting on November 12, 1996 and subsequently delivered to the
         Special Committee in writing to the effect that, as of such date, the
         consideration to be received by the holders of AES Chigen Class A
         Common Stock in the Amalgamation is fair to such holders from a
         financial point of view (a copy of Merrill Lynch's written opinion
         setting forth the assumptions made, general procedures followed,
         matters considered, and the limitations on the reviews undertaken, is
         attached as Appendix B hereto);
 
     (4) the opportunity for AES Chigen's shareholders to continue to share in
         the potential for long-term gains in AES Chigen through the ownership
         of AES Common Stock following the Amalgamation, while diversifying
         their risk through ownership of shares of AES, which invests in various
         countries;
 
     (5) the current environment in which AES Chigen operates and the potential
         benefits offered to AES Chigen by the transaction, including the
         rationalization of management and operating structure, the enhanced
         ability to focus on long term goals, the ability to use AES Common
         Stock as part of AES Chigen's compensation program and thereby enhance
         AES Chigen's ability to attract and retain qualified employees, and the
         greater resources available to the combined company;
 
     (6) the fact that the Original Amalgamation Agreement permits AES Chigen to
         terminate the Original Amalgamation Agreement to accept a Superior
         Proposal (as defined in "Description of the Amalgamation
         Agreement -- No Solicitation" below), recognizing, however, that AES's
         ownership position and certain of the terms of AES Chigen's Bye-laws
         may serve to deter certain bidders;
 
     (7) the other terms and conditions of the Original Amalgamation Agreement,
         including the parties' reciprocal representations, warranties and
         covenants and the conditions to their respective obligations; and
 
     (8) AES's existing ownership interest in AES Chigen and the terms of the
         Stock Purchase and Shareholder's Agreement between AES Chigen and AES
         which imposes restrictions on the ability of AES to make an unsolicited
         proposal for a combination transaction with AES Chigen.
 
     At a meeting of the Board of Directors of AES Chigen held immediately
thereafter, the Board of Directors by a unanimous vote (with one member absent),
based upon the recommendation of the Special Committee, determined (i) to

OPINION OF THE SPECIAL COMMITTEE'S FINANCIAL ADVISOR
 
     On November 12, 1996, Merrill Lynch delivered its oral opinion, which was
subsequently confirmed in a written opinion dated as of November 12, 1996 (the
"Merrill Lynch Opinion"), to the Special Committee to the effect that, as of
such date, the proposed consideration to be received by the holders of the AES
Chigen Class A Common Stock in the Amalgamation was fair to such holders from a
financial point of view.
 
     A copy of the Merrill Lynch Opinion, which sets forth the assumptions made,
general procedures followed, matters considered, and limitations on the reviews
undertaken, is attached as Appendix B hereto and incorporated herein by
reference. The Merrill Lynch Opinion is directed only to the fairness, from a
financial point of view, to the holders of the AES Chigen Class A Common Stock
of the proposed consideration to be received by them in the Amalgamation and
does not address AES Chigen's underlying business decision to effect the
Amalgamation or constitute a recommendation to any AES Chigen shareholder as to
how such shareholder should vote with respect to the Amalgamation. At the time
the Merrill Lynch Opinion was rendered, the Exchange Ratio included a downward
adjustment providing that in the event that as of the Effective Time the Average
Closing Price exceeded $50.00, shares of AES Chigen Class A Common Stock would
be canceled in consideration of the right to receive a fraction of a share of
AES Common Stock as would be determined by dividing $14.50 by the Average
Closing Price. As described in "The Amalgamation -- Background," the foregoing
downward adjustment to the Exchange Ratio was subsequently eliminated. The
summary of the Merrill Lynch Opinion set forth below is qualified in its
entirety by reference to the full text of such opinion attached as Appendix B
hereto. Shareholders are urged to read the opinion in its entirety.
 
     In arriving at the Merrill Lynch Opinion, Merrill Lynch, among other
things, (i) reviewed AES Chigen's Annual Report, Form 10-K and related financial
information for each of the two fiscal years in the period ended November 30,
1995 and AES Chigen's Form 10-Q and the related unaudited financial information
for each of the quarterly periods ending August 31, 1996, May 31, 1996 and
February 28, 1996; (ii) reviewed AES Chigen's initial public offering prospectus
dated February 24, 1994 and AES Chigen's Form S-3 Registration Statement dated
October 16, 1996; (iii) reviewed AES's Annual Report, Form 10-K and related
financial information for each of the five fiscal years in the period ended
December 31, 1995 and AES's Form 10-Q and the related unaudited financial
information for each of the quarterly periods ending March 31, 1996 and June 30,
1996; (iv) reviewed certain information, including financial forecasts, relating
to the business, earnings, cash flow, assets and prospects of AES Chigen and
AES, furnished to Merrill Lynch by AES Chigen and AES, respectively; (v)
conducted discussions with members of senior management of AES Chigen and AES
concerning their respective businesses and prospects; (vi) reviewed the
historical market prices and trading activity for the AES Chigen Class A Common
Stock and the AES Common Stock and compared them with those of certain publicly
traded companies which Merrill Lynch deemed to be comparable to AES Chigen and
AES, respectively; (vii) compared the results of operations of AES Chigen and
AES with those of certain companies which Merrill Lynch deemed to be comparable
to AES Chigen and AES, respectively; (viii) compared the proposed financial
terms of the Amalgamation with the financial terms of certain other mergers and
acquisitions which Merrill Lynch deemed to be relevant; (ix) reviewed a draft of
the Amalgamation Agreement dated November 9, 1996, which the Special Committee
advised Merrill Lynch would be identical in all material respects to the
Amalgamation Agreement as executed; and (x) reviewed
 
                                       32
<PAGE>   40
 
such other financial studies and analyses and performed such other
investigations and took into account such other matters as Merrill Lynch deemed
necessary.
 
     In preparing the Merrill Lynch Opinion, Merrill Lynch, with the Special
Committee's consent, relied on the accuracy and completeness of all information
supplied or otherwise made available to Merrill Lynch by AES Chigen and AES and
Merrill Lynch did not independently verify such information or undertake an
independent appraisal of the assets or liabilities of AES Chigen or AES. With
respect to the financial forecasts furnished by AES Chigen and AES, Merrill
Lynch assumed that such forecasts had been reasonably prepared and reflected the
best currently available estimates and judgment of AES Chigen's and AES's
management as to the expected future financial performance of AES Chigen or AES,
as the case may be. The Merrill Lynch Opinion necessarily was based on market,
economic, financial and other conditions as they existed and could be evaluated
as of the date of the Merrill Lynch Opinion.
 
     In connection with the preparation of the Merrill Lynch Opinion, Merrill
Lynch was not authorized by AES Chigen or its Board of Directors or the Special
Committee to solicit, nor did Merrill Lynch solicit, third-party indications of
interest for the acquisition of all or any part of AES Chigen.
 
     The following is a summary of the analyses performed by Merrill Lynch in
connection with the Merrill Lynch Opinion which were described by Merrill Lynch
in connection with a presentation to the Special Committee on November 12, 1996.
 
     Purchase Price Analysis.  Merrill Lynch performed an analysis of the
Amalgamation which indicated an implied offer value of $13.30 (the "Implied
Offer Value") per share of AES Chigen Class A Common Stock based on the November
8, 1996 AES Common Stock price of $45.88 per share and using an exchange ratio
of 0.29 shares of AES Common Stock per share of AES Chigen Class A Common Stock
(the "Base Exchange Ratio"). The Implied Offer Value represented a 5.0% discount
to the price per share of AES Chigen Class A Common Stock of $14.00 on November
8, 1996, a 4.3% premium to the price per share of AES Chigen Class A Common
Stock at November 6, 1996, a 6.4% premium to the price per share of AES Chigen
Class A Common Stock at October 14, 1996 (the date of Merrill Lynch's
appointment as financial advisor to the Special Committee), a 45.8% premium to
the price per share of AES Chigen Class A Common Stock at August 1, 1996 (the
date of commencement of discussions between AES and AES Chigen regarding the
Amalgamation), a 2.8% premium to the average price per share of AES Chigen Class
A Common Stock during the thirty day period ending on November 8, 1996, a 40.6%
premium to the average price per share of AES Chigen Class A Common Stock during
the twelve month period ending on November 8, 1996 and a 30.7% premium to the
average price per share of AES Chigen Class A Common Stock since the initial
public offering of the AES Chigen Class A Common Stock on February 24, 1994. An
analysis of the ratios of an offer value of $209.2 million (based on the Implied
Offer Value and the fully diluted number of shares outstanding of AES Chigen
Class A Common Stock (assuming the exercise of all options and their exchange
into AES Chigen Class A Common Stock) and the AES Chigen Class B Common Stock)
(the "Fully Diluted Offer Value") to AES Chigen's 1997 estimated earnings of
$11.4 million and 1998 estimated earnings of $34.4 million (in each case based
on base case projections as such projections are described under "Discounted
Cash Flow Analysis" below), yielded multiples of 18.4x and 6.1x, respectively.
An analysis of the ratios of the Fully Diluted Offer Value to 1997 estimated
earnings per share of $0.55 and 1998 estimated earnings per share of $1.35 (in
each case based on the report of a research analyst) yielded multiples of 24.2x
and 9.9x, respectively.
 
     Historical Stock Price and Exchange Ratio Analyses.  Merrill Lynch reviewed
the performance of the per share daily closing market price of the AES Chigen
Class A Common Stock over the period from February 24, 1994 to November 8, 1996
and compared such daily closing prices with the performance of the Standard &
Poor's 500 Index. Merrill Lynch also reviewed the performance of the per share
daily closing market price of the AES Common Stock over the same period and
compared such daily closing prices with the Standard & Poor's 500 Index. In
addition, Merrill Lynch compared the historical market price per share of the
AES Chigen Class A Common Stock to the historical market price per share of the
AES Common Stock for the period February 24, 1994 to November 8, 1996. Such
comparisons indicated that during the period from February 24, 1994 to November
8, 1996, the price per share of the AES Chigen Class A Common Stock
 
                                       33
<PAGE>   41
 
declined by 12.5%, the Standard & Poor's 500 Index increased by 57.4%, and the
price per share of the AES Common Stock increased by 98.9%. Such further
analysis indicated that the implied exchange ratio at market prices of the
number of shares of AES Common Stock necessary to equal one share of AES Chigen
Class A Common Stock over such period ranged from the lowest exchange ratio of
0.24 towards the end of the period to the highest exchange ratio of 0.76 towards
the beginning of the period. The Base Exchange Ratio was within such range.
 
     Analysis of Selected Publicly-Traded Comparable Companies.  Merrill Lynch
compared AES Chigen to two power companies operated in China deemed by Merrill
Lynch to be reasonably similar to AES Chigen: Huaneng Power and Shandong Huaneng
(the "Comparable Companies").
 
     Merrill Lynch determined trading multiples for the Comparable Companies of
price to book value as of June 30, 1996 and multiples for the Comparable
Companies of 1998 estimated price to earnings (based on selected research
reports). An analysis of the multiples for the Comparable Companies produced the
following results: (i) price to book value as of June 30, 1996 yielded an
average multiple of 1.11x; and (ii) 1998 estimated price to earnings yielded an
average multiple of 8.4x. Merrill Lynch then compared the results of such
analyses for the Comparable Companies to the corresponding results for AES
Chigen. Applying the average multiple for price to book value as of June 30,
1996, Merrill Lynch calculated an implied value of $11.50 per share of AES
Chigen Class A Common Stock. Applying the average multiple for 1998 estimated
price to earnings (based on the selected research reports referred to above),
Merrill Lynch calculated an implied value of $13.50 per share of AES Chigen
Class A Common Stock.
 
     Merrill Lynch considered the companies utilized in the above analysis to be
reasonably similar to AES Chigen because each participates in the power industry
in China, but, neither of these companies is identical to AES Chigen.
Accordingly, an analysis of the results of the foregoing is not purely
mathematical. Rather, it involves complex considerations and judgments
concerning differences in historical and projected financial and operating
characteristics of the companies and other factors that could affect the public
trading value of the comparable companies or company to which they are being
compared.
 
     Analysis of Selected Acquisition Transactions.  Merrill Lynch reviewed
certain publicly available information regarding 32 selected acquisition
transactions, announced since February 15, 1989, involving minority interest
repurchases and consideration in excess of $100 million (collectively, the
"Comparable Transactions"). The Comparable Transactions, in reverse
chronological order of public announcement were the following (listed by
seller/acquiror): GEICO Corp./Berkshire Hathaway Inc.; REN Corp.-USA/COBE
Laboratories (Gambro AB); Bic Corp./BIC SA; Club Med Inc./Club Mediterranee
S.A.; Fleet Mortgage Group Inc./Fleet Financial Group Inc.; Pacific
Telecom/PacifiCorp; Contel Cellular Inc./GTE Corp.; Chemical Waste Management
Inc./WMX Technologies Inc.; Ogden Projects Inc./Ogden Corp.; Diamond Shamrock
Offshore/Burlington Resources Inc.; Medical Marketing Group Inc./Medco
Containment Services Inc.; Brand Cos Inc./Rust International Inc.; PHLCORP
Inc./Leucadia National Corp.; Unocal Exploration Corp./Unocal Corp.; American
Television & Commun./Time Warner; United Artists Entertainment/Tele-
Communications Inc.; Hamilton Oil Corp./BHP Hldgs (USA) Inc. (Broken Hill);
Ocean Drilling & Exploration/Murphy Oil Corp.; US WEST New Vector Group Inc./US
West Inc.; Freeport-McMoRan Oil and Gas/Freeport-McMoRan Inc.; Mack Trucks
Inc./Renault Vehicules Industriels; Shearson Lehman Brothers Hldgs/American
Express Co.; Esselte Business Systems Inc./Esselte AB; Telerate Inc./Dow Jones &
Co. Inc.; HIMONT Inc./Montedison SpA; Wheelabrator Technologies
Inc./Wheelabrator Technologies Inc.; AL Williams Corp./Primerica Corp.; Fisher
Scientific Grp /Henley Group Inc.; WestMarc Communications
Inc./Tele-Communications Inc.; Centel Cable Television Co./Centel Corp.; Sizzler
Restaurants Intl. Inc./Collins Foods International; Enserch Exploration
Partners/ENSERCH Corp.
 
     For each of the Comparable Transactions Merrill Lynch compiled figures
illustrating, among other things, the premiums to market price at one day and
one month prior to the announcement date of each such Comparable Transaction.
The figures with respect to all of the Comparable Transactions produced (i) a
mean premium of 19.8% and a median premium of 19.2% at one day prior to the
announcement date and (ii) a mean premium of 27.6% and a median premium of 25.7%
at one month prior to the announcement date. The figures with respect to only
those Comparable Transactions involving consideration in the form of stock
 
                                       34
<PAGE>   42
 
produced (i) a mean premium of 18.3% and a median premium of 16.2% at one day
prior to the announcement date and (ii) a mean premium of 31.9% and a median
premium of 22.9% at one month prior to the announcement date. Merrill Lynch then
calculated the implied value per share of the AES Chigen Class A Common Stock
based on premiums derived from Merrill Lynch's analysis of the Comparable
Transactions and ranging from 20% to 30%. Based on its analysis, Merrill Lynch
calculated that the Comparable Transactions indicated a value range per share of
the AES Chigen Class A Common Stock that was from $15.00 to $16.25 per share,
more than the Implied Offer Value.
 
     Merrill Lynch considered the Comparable Transactions utilized in the above
analysis to be reasonably comparable to the Amalgamation because each involved
minority interest repurchases and consideration in excess of $100 million, but
no company, business or transaction used in the Comparable Transaction analysis
is identical to AES Chigen or the Amalgamation. Accordingly, an analysis of the
results of the foregoing is not purely mathematical. Rather, it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the public
trading value of the comparable companies or AES Chigen, the business segments
being compared, or the transaction values of the Comparable Transactions or the
Amalgamation.
 
     Discounted Cash Flow Analysis.  Merrill Lynch performed a low value range
and a high value range portfolio discounted cash flow analysis of AES Chigen,
based upon projections prepared by AES Chigen's management with respect to a
downside case, a base case and an upside case for the expected life of each
project in the portfolio. Merrill Lynch also performed a low value range and a
high value range project by project discounted cash flow analysis of AES Chigen
based upon projections prepared by AES Chigen's management with respect to the
base case for the expected life of each such project. Merrill Lynch was advised
that the downside case was based on the minimum electricity purchase commitments
set out in the power purchase agreements for AES Chigen's projects, the base
case was based on management's expected sales of electricity from AES Chigen's
projects and the upside case was based on management's expected additional sales
of electricity if the main customer of the Jiaozuo project completes a
significant expansion program by the year 1999. In all cases Merrill Lynch
included $20 million of franchise value based upon the estimate of premiums that
willing buyers would be willing to pay for market entry into potentially
attractive markets via established entities. Utilizing these projections,
Merrill Lynch calculated a range of values based upon the discounted net present
value of AES Chigen's stream of projected after-tax free cash flow over the
expected life of each project in the portfolio. In performing the portfolio
discounted cash flow analysis, Merrill Lynch applied discount rates reflecting a
weighted average cost of capital ranging from 13% to 17% to the consolidated
projected after-tax free cash flow for all of the projects in the portfolio. In
the project by project analysis Merrill Lynch applied discount rates ranging
from 13% to 17% to the projected after-tax free cash flow for each of the
operating and late-stage construction projects and 17% to 19% for each of the
development projects. Based on this analysis, Merrill Lynch calculated a range
of values per share of AES Chigen Class A Common Stock of $9.75 to $11.75,
$11.75 to $14.00, $12.25 to $14.50 and $11.44 to $13.78 in the downside case,
the base case, the upside case, and the project by project case, respectively.
The Implied Offer Value was above or within the range of such values.
 
     Present Value of Implied Future Stock Price.  Merrill Lynch calculated a
present value of the estimated price of the AES Chigen Class A Common Stock in
the year 2000. Merrill Lynch estimated AES Chigen's equity value in 2000 based
on price to earnings multiples of 11.0x to 13.0x of projected 2000 net income
(based on AES Chigen's base case projections). Such projected future stock price
was discounted (using equity discount rates of 15% and 18%) to a range of
present values of approximately $14.00 to $18.50, which in each case was above
the Implied Offer Value.
 
     AES Valuation.  In evaluating the value of the AES Common Stock proposed to
be issued in the Amalgamation, Merrill Lynch reviewed the market price of the
AES Common Stock and performed certain analyses based on certain research
reports and on AES's management projections. Such analyses included a comparable
public company analysis, a portfolio discounted cash flow analysis (based on
AES's management projections), a project by project discounted cash flow
analysis and an analysis of the present value of the implied future price of AES
Common Stock. These analyses indicated values per share of AES Common Stock of
$37.50 to $48.00, $49.25 to $58.50, $36.50 to $54.75 and $47.00 to $57.25,
respectively. The closing
 
                                       35
<PAGE>   43
 
market price of the AES Common Stock on the NYSE on November 8, 1996 of $45.88
per share was within or below each such range of values.
 
     Relative Implied Exchange Ratio Valuation.  Utilizing both the low and high
value ranges in the project by project discounted cash flow analysis for AES
Chigen and for AES, Merrill Lynch calculated an implied exchange ratio of the
number of shares of AES Common Stock that would be exchangeable for one share of
AES Chigen Class A Common Stock. Merrill Lynch's calculations produced the
following results: (i) with respect to AES Chigen's downside case, the implied
exchange ratio was 0.22 (utilizing the high value range for each of AES Chigen
and AES) and 0.27 (utilizing the low value range for each of AES Chigen and
AES); (ii) with respect to AES Chigen's base case, the implied exchange ratio
was 0.26 (utilizing the high value range for each of AES Chigen and AES) and
0.32 (utilizing the low value range for each of AES Chigen and AES) and (iii)
with respect to AES Chigen's upside case, the implied exchange ratio was 0.27
(utilizing the high value range for each of AES Chigen and AES) and 0.34
(utilizing the low value range for each of AES Chigen and AES). The Base
Exchange Ratio was within the range of implied exchange ratios for the base case
and the upside case.
 
     In addition Merrill Lynch calculated an implied exchange ratio based on its
review of the historical market value of the AES Chigen Class A Common Stock and
the AES Common Stock (based on an average implied exchange rate of 0.28 and 0.35
for the three months preceding November 8, 1996 and the twelve months preceding
November 8, 1996, respectively), its comparable public company analyses for AES
Chigen and AES and its calculation of the present value of the implied future
stock price of AES Chigen and of AES (using base case projections for AES Chigen
and AES). Merrill Lynch's calculations produced the following results: (i) with
respect to the historical market value the implied exchange ratio ranged from
0.28 to 0.35, (ii) with respect to the comparable public company analysis, the
implied exchange ratio ranged from 0.29 to 0.31 and (iii) with respect to the
present value of the implied future stock price, the implied exchange ratio
ranged from 0.30 to 0.32. The Base Exchange Ratio was within the range of the
implied exchange ratios for the historical market value and comparable company
analyses.
 
     Pro Forma Merger Analysis.  Utilizing the Base Exchange Ratio, Merrill
Lynch analyzed certain pro forma effects resulting from the Amalgamation,
including the effect on AES Chigen's projected earnings per share and the future
stock price of AES Chigen (in each case based on selected research reports and
on management forecasts).
 
     The foregoing summary does not purport to be a complete description of the
analyses performed by Merrill Lynch or of its presentation to the Special
Committee. The preparation of financial analyses and fairness opinions is a
complex process and is not necessarily susceptible to partial analysis or
summary description. Merrill Lynch believes that its analyses (and the summary
set forth above) must be considered as a whole, and that selecting portions of
such analyses and of the factors considered by them, without considering all
such analyses and factors, could create an incomplete and misleading view of the
processes underlying the analyses conducted by Merrill Lynch and its opinion.
Merrill Lynch did not make any attempt to assign specific weights to particular
analyses in preparing its opinion. In performing its analyses, Merrill Lynch
made numerous assumptions with respect to industry performance, general business
and economic conditions, and other matters, many of which are beyond the control
of AES Chigen and AES. Any estimates contained in Merrill Lynch's analyses are
not necessarily indicative of actual past or future results or values, which may
be significantly more or less favorable than such estimates. Estimates of values
of companies do not purport to be appraisals or to reflect the prices at which
such companies may actually be sold. Because such estimates are inherently
subject to uncertainty, none of Merrill Lynch, AES Chigen, AES, or any other
person assumes responsibility for their accuracy.
 
     As part of its investment banking business, Merrill Lynch is continuously
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions. The Special Committee retained Merrill Lynch to act as
its financial advisor because Merrill Lynch is an internationally recognized
investment banking firm with substantial experience in transactions similar to
the Amalgamation.
 
     Merrill Lynch has, in the past, provided financing services to AES Chigen,
and has received fees for the rendering of such services. In addition, in the
ordinary course of business, Merrill Lynch may actively trade
 
                                       36
<PAGE>   44
 
the AES Chigen Class A Common Stock as well as the AES Common Stock for Merrill
Lynch's own account, for the accounts of its affiliates and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     For its financial advisory services in connection with the Amalgamation,
AES Chigen paid Merrill Lynch US $100,000 as of October 15, 1996, the date of
its engagement by the Special Committee, and an additional fee of US $400,000 on
the date Merrill Lynch delivered the Merrill Lynch Opinion. AES Chigen has also
agreed to reimburse Merrill Lynch for its reasonable out-of-pocket expenses,
including fees and expenses of its legal counsel, and to indemnify Merrill Lynch
and certain related persons against certain liabilities in connection with its
engagement, including certain liabilities under the federal securities laws.

ACCOUNTING TREATMENT
 
     The Amalgamation will be accounted for as a purchase under generally
accepted accounting principles.
 
PROCEDURES FOR CANCELLATION OF AES CHIGEN CLASS A COMMON STOCK AND ISSUANCE OF
AES COMMON STOCK
 
     The manner of making payment for the cancellation of AES Chigen Class A
Common Stock in the Amalgamation is described below.
 
     At the Effective Time, AES shall make available to First Chicago Trust
Company of New York (the "Exchange Agent"), for the benefit of those persons who
immediately prior to the Effective Time were the holders of AES Chigen Class A
Common Stock, a sufficient number of certificates representing shares of AES
Common Stock required to effect the delivery of the aggregate Amalgamation
Consideration required to be issued pursuant to the Amalgamation Agreement (the
certificates representing shares of AES Common Stock comprising such aggregate
Amalgamation Consideration being hereinafter referred to as the "Exchange
Fund"). The Exchange Agent shall, pursuant to irrevocable instructions, deliver
the shares of AES Common Stock contemplated to be issued pursuant to the
Amalgamation Agreement. The Exchange Fund shall not be used for any other
purpose.
 
     Promptly after the Effective Time, the Exchange Agent shall mail to each
registered holder (other than Dissenting Shareholders) of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding AES Chigen Class A Common Stock (the "Certificates") (i) a form of
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon proper delivery
of the Certificates to the Exchange Agent) and (ii) instructions for use in
effecting the surrender of the Certificates for the Amalgamation Consideration.
Upon surrender of Certificates for cancellation to the Exchange Agent, together
with such letter of transmittal duly executed and any other required documents,
the holder of such Certificates shall be entitled to receive for each of the
shares of AES
 
                                       37
<PAGE>   45
 
Chigen Class A Common Stock represented by such Certificates the Amalgamation
Consideration and the Certificates so surrendered shall forthwith be canceled.
Until so surrendered, Certificates shall represent solely the right to receive
the Amalgamation Consideration and any cash in lieu of fractional shares of AES
Common Stock as contemplated by the Amalgamation Agreement with respect to each
of the shares of AES Chigen Class A Common Stock represented thereby. No
dividends or other distributions that are declared after the Effective Time on
shares of AES Common Stock and payable to the holders of record thereof after
the Effective Time will be paid to persons entitled by reason of the
Amalgamation to receive shares of AES Common Stock until such persons surrender
their Certificates. Upon such surrender, there shall be paid to the person in
whose name shares of AES Common Stock are issued any dividends or other
distributions having a record date after the Effective Time and payable with
respect to such shares of AES Common Stock between the Effective Time and the
time of such surrender. After such surrender there shall be paid to the person
in whose name shares of AES Common Stock are issued any dividends or other
distributions on such shares of AES Common Stock which shall have a record date
after the Effective Time and prior to such surrender and a payment date after
such surrender and such payment shall be made on such payment date. In no event
shall the persons entitled to receive such dividends or other distributions be
entitled to receive interest on such dividends or other distributions. If any
cash or any certificate representing shares of AES Common Stock is to be paid to
or issued in a name other than that in which the Certificate surrendered in
exchange therefor is registered, it shall be a condition of such exchange that
the Certificate so surrendered shall be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange shall pay
to the Exchange Agent any transfer or other taxes required by reason of the
issuance of certificates for such shares of AES Common Stock in a name other
than that of the registered holder of the Certificate surrendered, or shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable. Notwithstanding the foregoing, neither the Exchange Agent
nor any party to the Amalgamation Agreement shall be liable to a holder of AES
Chigen Class A Common Stock for any shares of AES Common Stock or dividends
thereon or cash in lieu of fractional interests delivered to a public official
pursuant to applicable escheat law. The Exchange Agent shall not be entitled to
vote or exercise any rights of ownership with respect to shares of AES Common
Stock held by it from time to time hereunder, except that it shall receive and
hold all dividends or other distributions paid or distributed with respect to
such shares of AES Common Stock for the account of the persons entitled thereto.
 
     Any portion of the Exchange Fund which remains unclaimed by the former
shareholders of AES Chigen for one year after the Effective Time shall be
delivered to AES, upon demand of AES, and any former shareholders of AES Chigen
shall thereafter look only to AES for payment of their claim for the
Amalgamation Consideration.
 
     If any Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the person claiming such Certificate to
be lost, stolen or destroyed and, if required by the Amalgamated Company, the
execution of an indemnity agreement by such person and/or the posting by such
person of a bond in such reasonable amount as the Amalgamated Company may
reasonably direct, as indemnity against any claim that may be made against it
with respect to such Certificate, the Exchange Agent will issue in exchange for
such lost, stolen or destroyed Certificate the shares of AES Common Stock, cash
in lieu of fractional shares of AES Common Stock and unpaid dividends and
distributions on shares of AES Common Stock deliverable in respect thereof
pursuant to the Amalgamation Agreement.
 
     No fractional shares of AES Common Stock shall be issued in the
Amalgamation and no fractional share interests will entitle the owner thereof to
vote or to any rights of a stockholder of AES. In lieu of any such fractional
shares, each holder of shares of AES Chigen Class A Common Stock who would
otherwise have been entitled to a fraction of a share of AES Common Stock upon
surrender of Certificates for cancellation pursuant to the Amalgamation
Agreement, after aggregating all shares of AES Common Stock which such holder
would be entitled to receive under the Amalgamation Agreement, will be paid an
amount in cash (without interest) equal to the closing price per share of AES
Common Stock on the NYSE on the trading day prior to the day on which the
Effective Time occurs (with fractions expressed as a decimal rounded to the
nearest one ten-thousandth) multiplied by the Exchange Ratio. As soon as
practicable after the determination of the amount of cash to be paid to former
shareholders of AES Chigen in lieu of any fractional interests, the
 
                                       38
<PAGE>   46
 
Exchange Agent shall make available in accordance with the Amalgamation
Agreement such amounts to such former shareholders.
 
     No transfers of shares of AES Chigen Class A Common Stock shall be made on
the share transfer books of AES Chigen after the close of business on the day
prior to the date of the Effective Time.
 
TREATMENT OF STOCK OPTIONS
 
     Pursuant to the AES China Generating Co. Ltd. Incentive Stock Option Plan
(the "AES Chigen Option Plan"), all outstanding options issued thereunder (the
"Options") will, as of the Effective Time, automatically and without any action
on the part of the holder thereof, become options for AES Common Stock. The AES
Chigen Option Plan shall remain in full force and effect after the Effective
Time unless otherwise amended or terminated in accordance with the plan
document. The number of shares of AES Common Stock to which holders of the
Options will be entitled will be that number of shares of AES Common Stock which
such holders would have received if such holders had exercised their options
immediately prior to the Effective Time. The date of grant for each such Option
shall be the date on which the corresponding option was originally granted.
 
     At the Effective Time, AES shall reserve for issuance the number of shares
of AES Common Stock that will become issuable upon the exercise of the Options.
Nothing shall affect the schedule of vesting (or the acceleration thereof) with
respect to the Options.
 
     As soon as practicable after the Effective Time, AES will file a
registration statement or registration statements on Form S-8 (or any successor
form), or another appropriate form with respect to the shares of AES Common
Stock subject to the Options, and shall use its best efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus contained therein) for so long as
any Options remain outstanding.
 
     After the Effective Time, no further grants will be made under the AES
Chigen Option Plan. It is the intention of AES to grant future stock options to
eligible AES Chigen employees under The AES Corporation Incentive Stock Option
Plan.
 
RESALE RESTRICTIONS
 
     Except as provided below, all shares of AES Common Stock received by AES
Chigen shareholders in the Amalgamation will be freely transferable. Subject to
the requirements of applicable law, certificates surrendered for exchange by any
person constituting an "affiliate" of AES Chigen for purposes of Rule 145 under
the Securities Act of 1933, as amended (the "Securities Act"), shall not be
exchanged for certificates representing shares of AES Common Stock until AES has
received from such person a written "affiliate" agreement in a form reasonably
acceptable to AES. AES Chigen shall use reasonable efforts to cause each such
person to deliver such written agreement to AES on or prior to the Closing Date.
 
                   DESCRIPTION OF THE AMALGAMATION AGREEMENT
 
     The following is a summary of material provisions of the Amalgamation
Agreement, which is included as Appendix A to this Proxy Statement/Prospectus
and is incorporated herein by reference. This summary is qualified in its
entirety by reference to the Amalgamation Agreement. For certain defined terms
used in the summary below, see "Description of the Amalgamation
Agreement -- Certain Definitions".
 
     The Amalgamation
 
     At the Effective Time, and upon the terms and subject to the conditions set
forth in the Amalgamation Agreement, AES Sub will be amalgamated with and into
AES Chigen in accordance with the Companies Act. AES Chigen will continue in the
form of the Amalgamated Company and shall operate under the name AES China
Generating Co. Ltd.

     The Amalgamation Consideration
 
     In the Amalgamation, each issued and outstanding share of AES Chigen Class
A Common Stock shall be canceled in consideration of the right to receive AES
Common Stock in the ratio of 0.2900 of a share of AES Common Stock; provided,
that should the average closing price of AES Common Stock on the NYSE (with
fractions expressed as a decimal rounded to the nearest one ten-thousandth) over
the 15 consecutive trading day period ending at the close of trading on the
third trading day immediately prior to the date of the Special Meeting (the
"Average Closing Price") be less than $45.00, shares of AES Chigen Class A
Common Stock will be canceled in consideration of the right to receive a
fraction of a share of AES Common Stock (expressed as a decimal rounded to the
nearest one ten-thousandth) as is determined by dividing $13.05 by the Average
Closing Price (the "Exchange Ratio" or the "Amalgamation Consideration"). AES
has the right not to consummate the Amalgamation if the Exchange Ratio, as so
determined, is greater than 0.3100. Fractional shares of AES Common Stock will
not be issuable in connection with the Amalgamation. AES Chigen shareholders
will receive cash, without interest, in lieu of fractional shares of AES Common
Stock.
 
     The following table indicates the Exchange Ratio assuming various Average
Closing Prices, with the resulting value to be received for each share of AES
Chigen Class A Common Stock:

(1) AES will have the right not to consummate the Amalgamation if the Exchange
    Ratio is greater than 0.3100.

     The Exchange Ratio, the $13.05 and $45.00 floor amounts, and the maximum
exchange ratio set forth as a condition to AES's obligations will be adjusted to
reflect fully the effect of any stock split (including a consolidation) of AES
Common Stock or a dividend payable in AES Common Stock, or any other
distribution of securities or dividend (in cash or otherwise) to holders of AES
Common Stock (including, without limitation, such a distribution made in
connection with a recapitalization, reclassification, merger, consolidation,
reorganization or similar transaction, but excluding any regular quarterly
dividend paid in cash) occurring or having a record date after the date of the
Amalgamation Agreement and prior to the Effective Time.
 
     As of the Effective Time, by virtue of the Amalgamation and without any
action on the part of the holders of any shares of AES Chigen Common Stock, or
any shares of AES Sub, each share of the capital stock of AES Sub issued and
outstanding immediately prior to the Effective Time shall be converted into and
become one fully paid and nonassessable share of common stock of the Amalgamated
Company. Each share of AES Chigen Common Stock that is owned by any subsidiary
of AES Chigen and each share of AES Chigen Common Stock that is owned by AES,
AES Sub or any other subsidiary of AES shall automatically be canceled and shall
cease to exist, and no consideration shall be delivered in exchange therefor.
 
     Directors, Executive Officers and Organizational Documents
 
     The Amalgamation Agreement provides that Roger W. Sant, Dennis W. Bakke and
Robert F. Hemphill, Jr. will be the directors of the Amalgamated Company, until
the earlier of their resignation or removal or until their respective successors
are duly elected and qualified, as the case may be.
 
     The Amalgamation Agreement also provides that the executive officers of AES
Chigen immediately prior to the Effective Time shall be the executive officers
of the Amalgamated Company, until the earlier of their resignation or removal or
until their respective successors are duly elected and qualified, as the case
may be.
 
     Further, the memorandum of association of AES Chigen as in effect
immediately prior to the Effective Time shall be the memorandum of association
of the Amalgamated Company until thereafter changed or amended as provided
therein or by applicable law; and the Bye-laws of AES Chigen shall be the
bye-laws of the Amalgamated Company, until thereafter changed or amended as
provided therein or by applicable law. The registration number of the
Amalgamated Company in Bermuda after the Effective Time shall be the same
registration number as that of AES Chigen immediately prior to the Effective
Time.
 
     Representations and Warranties
 
     The Amalgamation Agreement contains various customary representations and
warranties of AES, AES Sub and AES Chigen. The Amalgamation Agreement contains
representations and warranties of AES Chigen as to, among other things, its
organization, standing and corporate power, its subsidiaries, its capital
structure, its authority to execute and deliver the Amalgamation Agreement and
consummate the transactions contemplated thereby, due execution and delivery of
the Amalgamation Agreement, enforceability, noncontravention, the absence of the
need for consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Entity, the documents, including
financial statements, filed by AES Chigen with the Commission and the accuracy
of the information contained therein, the absence of any Material Adverse Change
in respect of AES Chigen, or any split, combination or reclassification of any
of its capital stock or any issuance or the authorization of any issuance of any
other securities in respect of, in lieu of or in substitution for shares of its
capital stock, any granting by AES Chigen to any officer of AES Chigen of any
increase in compensation, except in the ordinary course of business consistent
with prior practice, as was required under employment agreements or any increase
in severance or termination pay, except as was required under employment,
severance or termination agreements, or any damage, destruction or loss, whether
or not covered by insurance, that has or reasonably could be expected to have a
Material Adverse Effect in respect of AES Chigen or any change in accounting
methods, principles or practices by AES Chigen materially affecting its assets,
liabilities or business, except insofar as may have been required by a change in
GAAP, the absence of material litigation pending or, to the knowledge of AES
Chigen, threatened against AES Chigen or any of its subsidiaries, compliance
with applicable laws, brokers' fees and expenses, receipt of
 
                                       41
<PAGE>   49
 
an opinion of AES Chigen's financial advisor, and approval by the Special
Committee and AES Chigen's Board of Directors of the Amalgamation Agreement.
 
     The Amalgamation Agreement also contains representations and warranties of
AES and AES Sub as to, among other things, organization, standing and corporate
power, capital structure, authority to execute and deliver the Amalgamation
Agreement and consummate the transactions contemplated thereby, due execution
and delivery of the Amalgamation Agreement, enforceability, noncontravention,
the absence of a need for consent, approval, order or authorization of, or
registration, declaration or filing with, any Governmental Entity, the
documents, including financial statements, filed by AES with the Commission and
the accuracy of the information contained therein, the absence of any Material
Adverse Change in respect of AES, or any split, combination or reclassification
of any of its capital stock or any issuance or the authorization of any issuance
of any other securities in respect of, in lieu of or in substitution for shares
of its capital stock, or any damage, destruction or loss, whether or not covered
by insurance, that has or reasonably could be expected to have a Material
Adverse Effect in respect of AES or any change in accounting methods, principles
or practices by AES materially affecting its assets, liabilities or business,
except insofar as may have been required by a change in GAAP, the absence of
material litigation pending or, to the knowledge of AES, threatened against AES
or any of its subsidiaries, brokers' fees and expenses, and AES Sub's interim
operations.
 
     The Amalgamation Agreement provides that AES Chigen shall not be deemed to
have breached any of its representations and warranties if any senior officer of
AES (other than any such senior officer who is also an officer of AES Chigen)
had knowledge of such breach at the time the Amalgamation Agreement was
delivered by AES. In addition, the Amalgamation Agreement provides that no party
thereto shall have any liability for damages to the other parties for the breach
of any representations or warranties contained therein. The other parties' sole
remedy will be to not consummate the Amalgamation and/or to terminate the
Amalgamation Agreement.
 
     No Solicitation
 
     The Amalgamation Agreement provides that AES Chigen shall not, nor shall it
permit any of its subsidiaries to, nor shall it authorize or permit any officer,
director or employee of, or any investment banker, attorney or other advisor or
representative of, AES Chigen or any of its subsidiaries to, (i) solicit or
initiate, or encourage the submission of, any Takeover Proposal or (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any information with respect to, or take any other action to facilitate
any inquiries or the making of any proposal that constitutes, or may reasonably
be expected to lead to, any Takeover Proposal; provided, however, that, if in
the opinion of the Special Committee, after consultation with counsel, such
failure to act would be inconsistent with its fiduciary duties to AES Chigen or
the holders of AES Chigen Class A Common Stock under applicable law, AES Chigen
may, in response to an unsolicited Takeover Proposal, and subject to compliance
with its obligation to keep AES fully informed (as discussed below), (a) furnish
information with respect to AES Chigen to any person pursuant to a
confidentiality agreement and (b) participate in negotiations regarding such
Takeover Proposal. For purposes of the Amalgamation Agreement, "Takeover
Proposal" means any inquiry, proposal or offer from any person relating to any
direct or indirect acquisition or purchase of a substantial amount of assets of
AES Chigen or any of its subsidiaries (other than investors in the ordinary
course of business) or of over 20% of any class of equity securities of AES
Chigen or any of its subsidiaries or any tender offer or exchange offer that if
consummated would result in any person beneficially owning 20% or more of any
class of equity securities of AES Chigen or any of its subsidiaries, or any
amalgamation, consolidation, business combination, sale of substantially all
assets, recapitalization, liquidation, dissolution or similar transaction
involving AES Chigen or any of its subsidiaries other than the transactions
contemplated by the Amalgamation Agreement, or any other transaction the
consummation of which would reasonably be expected to impede, interfere with,
prevent or materially delay the Amalgamation or which would reasonably be
expected to dilute materially the benefits to AES of the transactions
contemplated thereby.
 
     Except as set forth in the Amalgamation Agreement or as required by Bermuda
law, the Special Committee shall not (i) withdraw or modify, or propose to
withdraw or modify, in a manner adverse to AES or AES Sub, the approval or
recommendation by such Special Committee of the Amalgamation or the
 
                                       42
<PAGE>   50
 
Amalgamation Agreement, (ii) approve or recommend, or propose to approve or
recommend, any Takeover Proposal or (iii) enter into any agreement with respect
to any Takeover Proposal. Notwithstanding the foregoing, if in the opinion of
the Special Committee, after consultation with counsel, failure to do any of the
foregoing would be inconsistent with its fiduciary duties to AES Chigen or the
holders of the AES Chigen Class A Common Stock under applicable law, the Special
Committee may (subject to the terms of the Amalgamation Agreement) withdraw or
modify its approval or recommendation of the Amalgamation or the Amalgamation
Agreement, approve or recommend a Superior Proposal, or enter into an agreement
with respect to a Superior Proposal, in each case relating to the receipt of a
Superior Proposal at any time after the second business day following AES's
receipt of written notice (a "Notice of Superior Proposal") advising AES that
the Special Committee has received a Superior Proposal, specifying the material
terms and conditions of such Superior Proposal and identifying the person making
such Superior Proposal; provided that AES Chigen shall not enter into an
agreement with respect to a Superior Proposal unless AES Chigen shall have
furnished AES with written notice no later than 12:00 noon, New York City time,
one day in advance of any date that it intends to enter into such agreement (it
being understood that such time periods may be concurrent). In addition, if AES
Chigen proposes to enter into an agreement with respect to any Takeover
Proposal, it shall concurrently with entering into such agreement pay, or cause
to be paid, to AES the Expenses. For purposes of the Amalgamation Agreement, a
"Superior Proposal" means any bona fide Takeover Proposal to acquire, directly
or indirectly, for consideration consisting of cash and/or securities, more than
50% of the shares of AES Chigen Class A Common Stock then outstanding or all or
substantially all the assets of AES Chigen and otherwise on terms which the
Special Committee determines in its good faith judgment (based on the advice of
a financial advisor of nationally recognized reputation) to be more favorable to
AES Chigen or the holders of the AES Chigen Class A Common Stock than the
Amalgamation.
 
     For the purposes of the Amalgamation Agreement, the parties thereto have
agreed that failure to take, following the receipt of a Takeover Proposal, an
action which the Special Committee reasonably believes is likely to result in a
Superior Proposal would be deemed to be a breach of the Special Committee's
fiduciary duties.
 
     The Amalgamation Agreement provides that AES Chigen shall immediately
advise AES orally and in writing of any request for information or of any
Takeover Proposal, or any inquiry with respect to or which could lead to any
Takeover Proposal, the material terms and conditions of such request, Takeover
Proposal or inquiry, and the identity of the person making any such Takeover
Proposal or inquiry. AES Chigen will keep AES fully informed of the status and
details (including amendments or proposed amendments) of any such request,
Takeover Proposal or inquiry.
 
     Access to Information
 
     The Amalgamation Agreement provides that AES Chigen shall, and shall cause
each of its subsidiaries to, afford to AES, and to AES's officers, employees,
accountants, counsel, financial advisors and other representatives, reasonable
access during normal business hours during the period prior to Effective Time to
all their respective properties, books, contracts, commitments, personnel and
records and, during such period, AES Chigen shall, and shall cause each of its
subsidiaries to, furnish promptly to AES (a) a copy of each report, schedule,
registration statement and other document filed by it during such period
pursuant to the requirements of federal or state securities laws and (b) all
other information concerning its business, properties and personnel as AES may
reasonably request.
 
     Cooperation and Reasonable Efforts
 
     AES, AES Sub and AES Chigen agreed to use all reasonable efforts to take,
or cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Amalgamation and the transactions contemplated thereby,
including approvals from Governmental Entities, the making of all necessary
registrations and filings (including filings with Governmental Entities, if
any), the taking of all reasonable steps as may be necessary to obtain an
approval or waiver from, or to avoid an action or proceeding by, any
Governmental Entity, the obtaining of all necessary consents, approvals or
 
                                       43
<PAGE>   51
 
waivers from third parties, the defending of any lawsuits or other legal
proceedings, whether judicial or administrative, challenging the Amalgamation
Agreement or the consummation of any of the transactions contemplated thereby,
including seeking to have any stay or temporary restraining order entered by any
court or other Governmental Entity vacated or reversed, and the execution and
delivery of any additional instruments necessary to consummate the transactions
contemplated thereby, and to fully carry out the purposes of, the Amalgamation
Agreement.
 
     AES, AES Sub and AES Chigen will give prompt notice to the other parties of
(i) any material representation or warranty made by it contained in the
Amalgamation Agreement that is qualified as to materiality becoming untrue or
inaccurate in any respect or any such material representation or warranty that
is not so qualified becoming untrue or inaccurate in any material respect or
(ii) the failure by it to comply with or satisfy in any material respect any
material covenant, condition or agreement to be complied with or satisfied by it
under the Amalgamation Agreement; provided, however, that no such notification
shall affect the representations, warranties, covenants or agreements of the
parties or the conditions to the obligations of the parties under the
Amalgamation Agreement.
 
     NYSE Listing Application
 
     Under the Amalgamation Agreement, AES has agreed to promptly prepare and
submit to the NYSE a listing application covering the shares of AES Common Stock
issuable in the Amalgamation, and to use its reasonable best efforts to obtain,
prior to the Effective Time, approval for the listing of such AES Common Stock,
subject to official notice of issuance. AES Chigen has agreed to cooperate fully
with AES with respect to such listing.

     The obligations of AES Chigen, AES Sub and AES to consummate the
Amalgamation are subject to the satisfaction of the following conditions: (a)

Chigen in accordance with the Companies Act and AES Chigen's Bye-laws; (b) no
Governmental Authority shall have enacted, issued, promulgated, enforced or

Governmental Entity or court, that is reasonably likely to result, directly or
indirectly, in any of the consequences referred to in subclauses (i) through
(iv) of clause (a) above; (c) there shall not have occurred any Material Adverse
Change in respect of AES Chigen; (d) all of the representations and warranties
of AES Chigen set forth in the Amalgamation Agreement that are qualified as to
materiality shall be true and correct and all such representations and
warranties that are not so qualified shall be true and correct in all material
respects, in each case as of the date of the Amalgamation Agreement and as of

Merrill Lynch shall not have withdrawn the Merrill Lynch Opinion.
 
     Employee Benefits Matters
 
     AES and AES Chigen have agreed that any employee benefit or compensation
plans, agreements or arrangements, including "employee benefit plans" as defined
in Section 3(3) of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), to which AES Chigen or any subsidiary of AES Chigen is a
party (together, the "AES Chigen Benefit Plans") in effect at the date of the
Amalgamation Agreement shall remain in effect until otherwise amended or
terminated after the Effective Time. To the extent the AES Chigen Benefit Plans
are amended or terminated, it is the current nonbinding intent of the parties
that employee benefit plans which are no less favorable, in the aggregate, than
the AES Chigen Benefit Plans shall be provided to the employees of AES Chigen.
Notwithstanding the foregoing, Options shall be
 
                                       45
<PAGE>   53
 
treated as discussed in "The Amalgamation -- Treatment of Stock Options." AES
and AES Chigen have also agreed to take all actions necessary and appropriate to
merge the AES China Generating Co. Ltd. Profit Sharing and Employee Stock
Ownership Plan into The AES Corporation Profit Sharing and Stock Ownership Plan.
 
     Termination
 
     The Amalgamation Agreement may be terminated and the Amalgamation and the
other transactions contemplated thereby may be abandoned at any time prior to
the Effective Time, notwithstanding any requisite approval and adoption of the
Amalgamation Agreement and the transactions contemplated thereby, as follows:
(a) by mutual written consent duly authorized by the Boards of Directors
(including the Special Committee) of each of AES and AES Chigen; (b) by either
AES or AES Chigen: (i) if as a result of the failure, occurrence or existence of
any of the conditions set forth in the Amalgamation Agreement the Amalgamation
shall not have occurred on or before April 30, 1997 (provided, however, that
this right to terminate the Amalgamation Agreement is not available to any party
whose failure to perform any of its obligations under the Amalgamation Agreement
results in the failure, occurrence or existence of any such condition) or (ii)
if any Governmental Entity shall have issued an Order permanently enjoining,
restraining or otherwise prohibiting the Amalgamation and such Order shall have
become final and nonappealable; (c) by AES in the event of a breach by AES
Chigen of any representation, warranty, covenant or other agreement contained in
the Amalgamation Agreement or any other development which (i) would give rise to
the failure of the conditions regarding AES Chigen's representations, warranties
and covenants and (ii) cannot be or has not been cured within 30 days after the
giving of written notice to AES Chigen; (d) by AES if (i) the Special Committee
shall have withdrawn or modified in a manner adverse to AES its approval or
recommendation of the Amalgamation or the Amalgamation Agreement, (ii) the
Special Committee shall have approved or recommended any Takeover Proposal
(including any Superior Proposal) in accordance with the Amalgamation Agreement
or (iii) AES Chigen shall have entered into any agreement with respect to any
Takeover Proposal (including any Superior Proposal) in accordance with the
Amalgamation Agreement; (e) by AES or AES Chigen if AES Chigen enters into a
definitive agreement in accordance with the Amalgamation Agreement, provided
that AES Chigen has complied with all provisions thereof, including the notice
provisions therein, and provided that AES Chigen makes simultaneous payment of
the Expenses; or (f) by AES Chigen in the event of a breach by AES in any
material respect of any representation, warranty, covenant or other agreement
contained in the Amalgamation Agreement, which (i) would give rise to the
failure of the conditions regarding AES's representations, warranties and
covenants and (ii) cannot be or has not been cured within 30 days after the
giving of written notice to AES, except, in any case, such failures which, in
the aggregate, would not have a Material Adverse Effect in respect of AES.
 
     In the event of termination of the Amalgamation Agreement by either AES
Chigen or AES, the Amalgamation Agreement shall become void and have no effect,
without any liability or obligation on the part of AES or AES Chigen, other than
AES's and AES Chigen's respective representations concerning brokers, their
respective covenants concerning fees and expenses and certain other provisions,
and except to the extent that such termination results from the willful and
material breach by a party of any of its representations, warranties, covenants
or agreements set forth in the Amalgamation Agreement.
 
     Amendment, Extension and Waiver
 
     The Amalgamation Agreement may be amended by the parties at any time. The
Amalgamation Agreement may not be amended except by an instrument in writing
signed on behalf of each of the parties.
 
     At any time prior to the Effective Time, the parties may (a) extend the
time for the performance of any of the obligations or other acts of the other
parties, (b) waive any inaccuracies in the representations and warranties
contained in the Amalgamation Agreement or in any document delivered pursuant to
the Amalgamation Agreement or (c) waive compliance with any of the agreements or
conditions contained in the Amalgamation Agreement. Any agreement on the part of
a party to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party. The failure of any party
to the
 
                                       46
<PAGE>   54
 
Amalgamation Agreement to assert any of its rights under the Amalgamation
Agreement or otherwise shall not constitute a waiver of those rights.
 
     A termination, amendment, extension or waiver of the Amalgamation Agreement
or any other action pursuant to the Amalgamation Agreement shall, in order to be
effective, require, in the case of AES Chigen, action by the Special Committee,
or action by the duly authorized designee of such Special Committee. Further,
any action permitted to be taken by AES Chigen pursuant to the Amalgamation
Agreement may be taken by the Special Committee on behalf of AES Chigen.
 
     Indemnification; Insurance.
 
     AES Chigen shall not, and for a period of six years from and after the
Effective Time AES and the Amalgamated Company shall not, amend the provisions
of the Bye-Laws providing for the indemnification of directors and officers of
AES Chigen in any manner adverse to such directors and officers. For a period of
six years after the Effective Time, AES shall cause to be maintained in effect
the current policies of directors' and officers' liability insurance maintained
by AES Chigen (provided that AES may substitute therefor policies of at least
the same coverage and amounts containing terms and conditions which are no less
advantageous) with respect to claims arising from facts or events which occurred
before the Effective Time to the extent available. The indemnification and
insurance provisions are intended to be for the benefit of, and shall be
enforceable by, each indemnified party, his or her heirs and representatives.
 
     Termination of Certain Agreements.
 
     AES and AES Chigen have agreed that each of the Stock Purchase and
Shareholder's Agreement, and the Non-Competition and Non-Disclosure Agreement,
dated as of December 29, 1993, and amended and restated as of February 1, 1994,
by and between AES and AES Chigen, shall be terminated as of the Effective Time.

                       RIGHTS OF DISSENTING SHAREHOLDERS
 
     Any holder of shares of AES Chigen Class A Common Stock who does not vote
in favor of the Amalgamation and who is not satisfied that he or she has been
offered fair value for his or her shares may within one month of the giving of
the notice of the Class A Meeting and the Special Meeting apply to the Supreme
Court of Bermuda (the "Court") to appraise the fair value of all of such
holder's shares.
 
     Under the Amalgamation Agreement, AES Chigen shall give AES (i) prompt
notice of any demands for appraisal of shares of AES Chigen Class A Common Stock
received by AES Chigen and (ii) the opportunity to participate in and direct all
negotiations and proceedings with respect to any such demands. AES Chigen shall
not, without the prior written consent of AES, make any payment with respect to,
or settle, offer to settle or otherwise negotiate, any such demands. The
relevant portion of Section 106 of the Companies Act is as follows:
 
          (6) Any shareholder who did not vote in favour of the amalgamation and
     who is not satisfied that he has been offered fair value for his shares may
     within one month of the giving of the notice referred to in subsection (2)
     apply to the Court to appraise the fair value of his shares.
 
          (6A) Subject to subsection (6B), within one month of the Court
     appraising the fair value of any shares under subsection (6) the company
     shall be entitled either --
 
             (a) to pay the dissenting shareholder an amount equal to the value
        of his shares as appraised by the Court; or
 
             (b) to terminate the amalgamation in accordance with subsection
        (7).
 
          (6B) Where the Court has appraised any shares under subsection (6) and
     the amalgamation has proceeded prior to the appraisal then, within one
     month of the Court appraising the value of the shares, if the amount paid
     to the dissenting shareholder for his shares is less than that appraised by
     the Court the amalgamated company shall pay to such shareholder the
     difference between the amount paid to him and the value appraised by the
     Court.
 
          (6C) No appeal shall lie from an appraisal by the Court under this
     section.
 
          (6D) The costs of any application to the Court under this section
     shall be in the discretion of the Court.
 
          (7) An amalgamation agreement may provide that at any time before the
     issue of a certificate of amalgamation the agreement may be terminated by
     the directors of an amalgamating company, notwithstanding approval of the
     agreement by the shareholders of all or any of the amalgamating companies.
 
     In a determination of fair value, the Court has considerable discretion.
There is little developed case law in Bermuda regarding the determination of
fair value. The applicable provisions of the Companies Act are modeled on the
comparable provisions of the Canada Business Corporations Act, and thus,
Canadian authorities would be instructive. Generally accepted valuation
principles recognized in the leading Canadian decision include the market value
approach, the assets approach, the earnings or investment value approach or some
combination thereof and the Court would use whichever method it thought
appropriate to ascertain the fair value of AES Chigen Class A Common Stock. The
Court can assess fair value at a figure higher than, equal to or lower than the
consideration payable in the Amalgamation.
 
     The Court is the exclusive venue for the institution of proceedings to
appraise fair value pursuant to Section 106 of the Companies Act. There is no
right of appeal from an appraisal by the Court. An award in respect of the costs
of an appraisal application by a dissenting shareholder is in the discretion of
the Court and is not statutorily determined.

                           MATERIAL TAX CONSEQUENCES
 
     The discussion appearing below under "United States Federal Income
Taxation" generally summarizes the material United States federal income tax
consequences of the Amalgamation for holders of AES Chigen Class A Common Stock
who hold such stock as a capital asset (generally, property held for
investment). The discussion under "Bermuda Taxation" generally summarizes the
material Bermuda tax consequences of the Amalgamation. The discussion does not
deal with all possible tax consequences of the Amalgamation and does not purport
to deal with the tax consequences applicable to all categories of investors,
some of which (such as dealers in securities, insurance companies and tax-exempt
entities) may be subject to special rules. In particular, the discussion does
not address the tax consequences under state or local law or the laws of
countries other than the United States and Bermuda. Furthermore, the proper
characterization under U.S. tax law of reorganization transactions accomplished
under foreign law that may not be identical in all legal particulars to merger
and other reorganization transactions accomplished under U.S. laws is a subject
on which there are no authoritative precedents involving transactions similar to
the Amalgamation. Accordingly, prospective investors should consult their own
tax advisors regarding the particular tax consequences to them of the
Amalgamation. The following discussion is based upon laws and relevant
interpretations thereof in effect as of the date of this Proxy
Statement/Prospectus, all of which are subject to change.
 
UNITED STATES FEDERAL INCOME TAXATION
 
     In the opinion of Chadbourne & Parke LLP, counsel to AES, the following are
the material United States federal income tax consequences of the Amalgamation.
 
     AES CHIGEN AND AES.  The Amalgamation is expected to be treated as a
tax-free reorganization pursuant to Section 368(a)(l)(B) of the Code. AES Chigen
will make no exchange or disposition giving rise to taxable gain or loss.
 
     U.S. HOLDERS OF AES CHIGEN STOCK.  For purposes of the following
discussion, the term "U.S. Holder" means a beneficial owner of shares of AES
Chigen who is (a) an individual who is a United States citizen or resident, (b)
a corporation, partnership (including an entity treated as a corporation or
partnership for United States tax purposes) or other entity created or organized
under the laws of the United States or any political subdivision thereof, or (c)
an estate or trust or any other person that is otherwise subject to United
States federal income tax on a net basis with respect to its worldwide income.
With respect to the tax year of any trust that begins after December 31, 1996, a
U.S. Holder shall mean a trust whose administration is subject to the primary
supervision of a United States court and which has one or more United States
fiduciaries who have the authority to control all substantial decisions of the
trust. The term "Non-U.S. Holder" means a beneficial owner of shares of AES
Chigen who is not a U.S. Holder.
 
     Unless the special rules discussed below apply (see "-- Possible
Application of Passive Foreign Investment Company Rules"), the exchange by a
U.S. Holder of shares of AES Chigen Class A Common Stock for shares of AES
Common Stock pursuant to the Amalgamation will have the following consequences:
(i) except for cash received in lieu of a fractional share, no gain or loss will
be recognized upon the exchange of shares of AES Chigen Class A Common Stock;
(ii) cash received in lieu of a fractional share will be treated as capital gain
or loss in an amount equal to the difference between the cash received and the
shareholder's basis in the fractional share; (iii) the aggregate basis of shares
of the AES Common Stock received will be the same as the aggregate basis of the
shares of AES Chigen Class A Common Stock exchanged therefor (less the U.S.
Holder's basis in any fractional share); and (iv) the holding period of shares
of the AES Common Stock will include the period during which such shareholder
held the AES Chigen Class A Common Stock exchanged therefor.
 
     POSSIBLE APPLICATION OF PASSIVE FOREIGN INVESTMENT COMPANY RULES.  It is
possible that AES Chigen could be characterized as a Passive Foreign Investment
Company (a "PFIC") as defined in Section 1296 of the Code. If so, the tax
consequences to a shareholder of AES Chigen Class A Common Stock upon the
exchange of shares of AES Chigen Class A Common Stock for shares of AES Common
Stock will depend on the application of an additional set of rules.
 
                                       49
<PAGE>   57
 
     Under Section 1291(f) of the Code, to the extent that the IRS so provides
in regulations, gain will be recognized upon the exchange of shares of a PFIC in
a transaction that would otherwise be treated as a non-recognition transaction,
including a reorganization of the type contemplated by the Amalgamation. The IRS
has issued regulations under Section 1291(f) in proposed form (the "Proposed
Regulations"). While the Proposed Regulations would generally require the
recognition of gain upon an exchange of shares of a PFIC pursuant to certain
types of tax-free reorganizations, they provide an exception to gain recognition
in the case of tax-free reorganizations that qualify under Section 368(a)(1)(B)
of the Code, assuming other conditions are met. It is anticipated that the
conditions of the Proposed Regulations will be met; accordingly, because the
Amalgamation is expected to qualify under Section 368(a)(1)(B) of the Code, no
gain or loss should be recognizable by a U.S. Holder of AES Chigen Class A
Common Stock pursuant to the Amalgamation under the Proposed Regulations. If,
however, the Amalgamation does not constitute a tax-free reorganization under
Section 368(a)(1)(B) of the Code, certain U.S. Holders could be required to
recognize gain or loss under the Proposed Regulations even if the Amalgamation
constituted a tax-free reorganization under another subsection of Section 368(a)
of the Code.
 
     The Proposed Regulations are stated to be effective for transactions
occurring on or after April 1, 1992. If the Proposed Regulations are adopted in
their current form, the tax consequences to a U.S. Holder of AES Chigen Class A
Common Stock will be as set forth in the preceding paragraph. However, because
they have not yet been adopted in final form, they are not currently effective
and there is no assurance they will be finally adopted in the form and with the
effective date proposed. Nevertheless, the IRS has announced that, in the
absence of final regulations, taxpayers may apply reasonable interpretations of
the Code provisions applicable to PFICs and that it considers the rules set
forth in the Proposed Regulations to be reasonable interpretations of those Code
provisions.
 
     In the absence of a final regulation requiring recognition of gain upon the
exchange of shares of a PFIC in the circumstances presented in the Amalgamation
and in light of the fact that under the Proposed Regulations such gain
recognition would not be required if, as discussed above, the Amalgamation
constitutes a tax-free reorganization under Section 368(a)(1)(B) of the Code,
Chadbourne & Parke LLP believes that a shareholder of AES Chigen Class A Common
Stock may reasonably conclude that such gain recognition is not required, even
if AES Chigen were determined to be a PFIC.
 
     The PFIC provisions are complex and subject to interpretation. As discussed
above, the effect of relevant portions of those provisions is not settled. Under
these circumstances, each U.S. Holder of the shares of AES Chigen Class A Common
Stock is urged to consult his own tax advisor with respect to the possible
application and effect of those provisions.
 
     NON-U.S. HOLDERS.  A Non-U.S. Holder of shares of AES Chigen Class A Common
Stock will be exempt from U.S. federal income and withholding tax on any gain
realized with respect to the exchange of such shares for shares of AES Common
Stock pursuant to the Amalgamation unless the Amalgamation does not qualify as a
reorganization pursuant to Section 368(a) of the Code and (i) such gain is
effectively connected with the conduct by such Non-U.S. Holder of a trade or
business within the United States, or (ii) such gain is realized by an
individual Non-U.S. Holder who holds such shares as capital assets and is
present in the United States for at least 183 days in the taxable year of the
sale and certain other conditions are met.
 
BERMUDA TAXATION
 
     In the opinion of Appleby, Spurling & Kempe, Bermuda counsel to AES, the
following are the material Bermuda tax consequences of the Amalgamation.
 
     Bermuda currently does not impose any tax on the income, capital gains,
sales, dividends, remittances or accumulated profits of any person or entity.
 
     AES Sub and AES Chigen have each obtained from the Minister of Finance of
Bermuda under The Exempted Undertakings Tax Protection Act, 1966 (as amended) an
undertaking that until March 28, 2016, in the event of there being enacted in
Bermuda any legislation imposing tax computed on profits or income, or
 
                                       50
<PAGE>   58
 
computed on any capital asset, gain or appreciation, or imposing any tax in the
nature of estate duty or inheritance tax, such tax shall not be applicable to
either of them or to any of their respective operations, or to their shares,
debentures or other obligations except in so far as such tax applies to persons
ordinarily resident in Bermuda and holding such shares, debentures or other
obligations of AES Sub or AES Chigen or to any land leased or let to either of
them.
 
     AES Sub and AES Chigen are each liable to pay the Bermuda Government an
annual registration fee. In the case of AES Sub, such fee is $1,680 and in the
case of AES Chigen the fee is $25,000 based on their respective assessable
capital, consisting of authorized share capital and share premium account.
 
                               FEES AND EXPENSES
 
     AES has retained First Chicago Trust Company of New York to act as the
Exchange Agent in connection with the Amalgamation. The Exchange Agent will
receive reasonable and customary compensation for its services, will be
reimbursed for certain reasonable out-of-pocket expenses and will be indemnified
against certain liabilities in connection therewith, including certain
liabilities under the federal securities laws. The Exchange Agent has not been
retained to make solicitations or recommendations in its role as Exchange Agent.
 
     Proxies will be solicited by mail, telephone or other means of
communication. AES Chigen has retained the services of Corporate Investor
Communications, Inc. to assist in the solicitation of proxies from shareholders
for a fee, including their expenses, estimated at $3,750. In addition,
solicitation may be made by directors, officers, and regular employees of AES
Chigen. AES Chigen will reimburse brokerage firms, custodians, nominees and
fiduciaries in accordance with the rules of the National Association of
Securities Dealers, Inc., for reasonable expenses incurred by them in forwarding
materials to the beneficial owners of shares. The entire cost of solicitation
will be borne by AES Chigen.
 
     The consideration to be provided to holders of AES Chigen Class A Common
Stock pursuant to the Amalgamation will be shares of AES Common Stock and cash
in lieu of fractional shares. Under the Amalgamation Agreement, except as
provided below, all fees and expenses incurred in connection with the
Amalgamation, the Amalgamation Agreement and the transactions contemplated
thereby shall be paid by the party incurring such fees or expenses, whether or
not the Amalgamation is consummated. However, AES Chigen shall pay, or cause to
be paid, to AES all of AES's out-of-pocket expenses in an amount up to but not
to exceed $750,000 (the "Expenses") upon demand if (i) AES terminates the
Amalgamation Agreement as a result of the Special Committee's approval or
recommendation of a Takeover Proposal, (ii) AES Chigen terminates the
Amalgamation Agreement and enters into an agreement with respect to a Takeover
Proposal or (iii) prior to the termination of the Amalgamation Agreement (other
than by AES Chigen as a result of a material, incurable breach by AES), a
Takeover Proposal shall have been made and within one year of such termination,
AES Chigen enters into an agreement with respect to, approves or recommends or
takes any action to facilitate, such Takeover Proposal.
 
                              REGULATORY APPROVALS
 
GENERAL
 
     AES and AES Chigen are aware of no U.S. federal, state or local government
permits, licenses or regulatory approvals material to their respective
businesses that must be obtained for consummation of the Amalgamation, other
than compliance with federal and state securities laws. The Amalgamation was not
subject to the pre-merger notification provisions of the HSR Act.
 
     Under the Amalgamation Agreement, AES and AES Chigen have agreed to use all
reasonable efforts to consummate the transactions contemplated thereby. See
"Description of the Amalgamation Agreement -- Cooperation and Reasonable
Efforts."

STATE TAKEOVER LAWS
 
     A number of states have adopted takeover laws and regulations which
purport, to varying degrees, to be applicable to attempts to acquire securities
of corporations which are incorporated in such states or which have, or whose
business operations have substantial economic effects in such states, or which
have substantial assets, security holders, principal executive offices or
principal places of business therein. However, in 1982, the Supreme Court of the
United States, in Edgar v. Mite Corp., invalidated on constitutional grounds the
Illinois Business Takeovers Act, which, as a matter of state securities law,
made takeovers of corporations meeting certain requirements more difficult, and
the reasoning in such decision is likely to apply to certain other state
takeover statutes. In 1987, however, in CTS Corp. v. Dynamics Corp. of America,
the Supreme Court of the United States held that the State of Indiana could, as
a matter of corporate law and, in particular, those aspects of corporate law
concerning corporate governance, constitutionally disqualify a potential
acquiror from voting on the affairs of a target corporation without the prior
approval of the remaining stockholders, provided that such laws were applicable
only under certain conditions. Subsequently, in TLX Acquisition Corp. v. Telex
Corp., a federal district court in Oklahoma ruled that the Oklahoma takeover
statutes were unconstitutional insofar as they applied to corporations
incorporated outside of Oklahoma in that they would subject such corporations to
inconsistent regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a
federal district court in Tennessee ruled that four Tennessee takeover statutes
were unconstitutional as applied to corporations incorporated outside Tennessee.
This decision was affirmed by the United States Court of Appeals for the Sixth
Circuit. In December 1988, a federal district court in Florida held in Grand
Metropolitan PLC v. Butterworth that the provisions of the Florida Affiliated
Transactions Act and the Florida Control Share Acquisition Act were
unconstitutional as applied to corporations incorporated outside of Florida.
 
     AES has not attempted to comply with any state takeover statutes in
connection with the Amalgamation. AES reserves the right to challenge the
validity or applicability of any state law allegedly applicable to the
Amalgamation and nothing in this Proxy Statement/Prospectus nor any action taken
in connection herewith is intended as a waiver of that right. In the event that
any state takeover statute is found applicable to the Amalgamation, AES might be
unable to consummate the Amalgamation or be delayed in continuing or
consummating the Amalgamation. In such case, AES may not be obligated to carry
out the Amalgamation. See "Description of the Amalgamation
Agreement -- Conditions."
 
                                 THE COMPANIES
 
BUSINESS OF AES
 
     With a presence in over 35 countries, AES is a global power company
committed to supplying electricity to customers world-wide in a socially
responsible way. AES, based in Arlington, Virginia, markets power principally
from electric generating facilities that it develops, owns and operates. AES was
one of the original entrants in the independent power market and today is one of
the world's largest global power companies, based on net equity ownership of
generating capacity (in megawatts) in operation or under construction. AES
Common Stock is listed and principally traded on the NYSE Composite Transaction
reporting system (Symbol: AES).
 
     Over the last six years, AES has experienced significant growth. This
growth has resulted primarily from the development and construction of new
plants ("greenfield development") and also from the acquisition of existing
plants, primarily through competitively bid privatization initiatives outside
the United States.
 
     In part, AES's strategy in helping meet the world's need for electricity is
to participate in competitive power generation markets as they develop either by
greenfield development or by acquiring and operating existing facilities in
these markets.
 
     Other elements of AES's strategy include:
 
     - Supplying energy to customers at the lowest cost possible, taking into
       account factors such as reliability and environmental performance.
 
                                       52
<PAGE>   60
 
     - Constructing or acquiring projects of a relatively large size (generally
larger than 100 megawatts).
 
     - Entering into power sales contracts with electric utilities or other
customers with credit strength.
 
     AES also strives for operating excellence as a key element of its strategy,
which it believes it accomplishes by minimizing organizational layers and
maximizing company-wide participation in decision-making. AES has attempted to
create an operating environment that results in safe, clean and reliable
electricity generation. Because of this emphasis, AES prefers to operate all
facilities which it develops or acquires; however, there can be no assurance
that AES will have operating control of all of its facilities in the future.
 
     See "Recent Developments -- AES".
 
BUSINESS OF AES CHIGEN
 
     AES Chigen is a leading independent power generation company in China and
one of the few international developers that has successfully completed the
development of electric power projects in the country. AES Chigen was founded in
December 1993 by AES to serve as the exclusive vehicle for AES to develop,
acquire, finance, construct, own and operate electric power generation
facilities in the PRC. AES currently holds 48% of the equity capital of AES
Chigen and AES, as the holder of all of the AES Chigen Class B Common Stock, has
the right to elect one-half of the Board of Directors of AES Chigen. Thus, AES
may be deemed to control the management and operation of AES Chigen. AES does
not, however, have control of AES Chigen in respect of approval of the
Amalgamation; pursuant to the Stock Purchase and Shareholder's Agreement, AES
was required to obtain the consent of the Class A Directors of AES Chigen prior
to entering into the Amalgamation Agreement. See "AES Chigen's Relationship with
AES -- Stock Purchase and Shareholder's Agreement".
 
     To respond to significant opportunities in China, AES, through a
wholly-owned subsidiary, opened an office in Hong Kong in early 1993. Following
the incorporation of AES Chigen, AES purchased shares of AES Chigen Class B
Common Stock for $50.0 million and, in early 1994, AES Chigen completed an
initial public offering of shares of its Class A Common Stock, which provided
AES Chigen with net proceeds, after underwriting commissions and discounts, of
$151.9 million. AES Chigen Class A Common Stock is quoted and principally traded
on NASDAQ NMS (Symbol: CHGNF).
 
     Since commencing business, AES Chigen has committed $259.6 million and as
of January 31, 1997 has invested $165.7 million in eight power projects in
operation or under construction in the PRC having an aggregate nameplate
capacity of approximately 818 MW (approximately 422 MW of which is attributable
to AES Chigen's interests in certain joint venture enterprises). These joint
ventures' projects include coal, oil and natural gas-fired and hydropower plants
located in six different provinces in China.
 
     AES Chigen plans to build upon its position as a leading independent power
producer in China through the continued development of and investment in
electric power projects. AES Chigen has signed joint venture contracts and is in
various stages of negotiation to develop five additional power projects with an
aggregate nameplate capacity of approximately 2,900 MW (approximately 805 MW of
which is attributable to AES Chigen's interests in the proposed project
companies). If all of these projects are completed, the estimated total
investment commitment by AES Chigen would be approximately $209.7 million.

OVERVIEW
 
     AES Chigen, directly or through one of its wholly-owned offshore
subsidiaries, has formed sino-foreign Joint Ventures, each with one or more
Chinese entities as partners, to develop, construct, own and operate each of the
electric power plants described in this section. Two of the power plants -- Cili
Misty Mountain and Yangchun Sun Spring -- are financed solely with registered
capital (equity). Four of the power plants -- Aixi Heart River, Jiaozuo Aluminum
Power, Chengdu Lotus City and Wuxi Tin Hill -- are financed with a combination
of registered capital and shareholder loans. One of the power plants -- Wuhu
Grassy Lake -- is financed by registered capital, shareholder loans and third
party debt. One other project -- Hefei Prosperity Lake -- which is currently
financed by registered capital and shareholder loans, may also be in the future
financed by third party debt.
 
     All of AES Chigen's power plants are owned by cooperative joint ventures,
except for one of the projects -- Wuhu Grassy Lake -- which is owned by an
equity joint venture. The joint venture contracts for three of the cooperative
joint ventures -- Wuxi Tin Hill, Aixi Heart River and Chengdu Lotus
City -- provide for the liquidation of the project assets at the end of the term
of the Joint Venture. The cooperative joint venture contracts relating to the
remaining four projects provide for the transfer of all of the fixed assets of
the Joint Venture to the Chinese partners without charge at the end of the Joint
Venture term. Three of these four provide for the recovery of AES Chigen's
registered capital during the term of the Joint Venture. AES Chigen expects that
its distributions under the fourth cooperative joint venture contract will
permit it to recover its registered capital and earn a return on investment.
 
     Revenues from the power plants are generally used to pay operating
expenses, taxes and financing costs and allocated to provide reserves for
employee social welfare benefits and other matters as required by law. Repayment
of principal and interest of third party loans (if any) and shareholder loans
(if any) of the Joint
 
                                       54
<PAGE>   62
 
Ventures has priority over distributions of profit to the Joint Venture
partners. Dividends are generally distributed to AES Chigen and its partners by
the Joint Ventures pursuant to board resolutions. In a number of cases with
respect to the Joint Ventures described in this section, AES Chigen has a
priority in the payment of dividends over the Chinese partners to the Joint
Venture. In certain cases, where AES Chigen is not entitled to appoint a
majority of the board of directors of a Joint Venture, the declaration of
dividends or other equity distributions by such Joint Venture may depend on the
assent of the other directors of the Joint Venture.
 
     Pursuant to certain shareholder loan contracts, AES Chigen has committed to
provide shareholder loans to several of the Joint Ventures. In each case the
applicable Joint Venture has either registered the shareholder loan with the
relevant branch of the State Administration of Foreign Exchange of the Central
Government (the "SAFE") if the loan has been drawn, or the Joint Venture will
register the shareholder loan with the relevant branch of the SAFE when the loan
is drawn by the Joint Venture. The payment of principal and interest to AES
Chigen with respect to its shareholder loans to the Joint Ventures is made in
accordance with schedules established by the relevant shareholder loan
contracts.
 
     Each of the Joint Ventures described in this section has entered into one
or more power purchase contracts for the sale of the electricity from its power
plant on a minimum take-or-pay basis. The power purchase contracts generally
require that the power purchaser purchase a specified annual minimum amount of
electricity generated by the power plant during the term of the power purchase
contract at a fixed price or pursuant to a tariff formula set forth in the power
purchase contract. In all but two cases -- Cili Misty Mountain and Yangchun Sun
Spring -- the power purchase contracts also contain incentives to encourage the
power purchaser to purchase greater than the agreed minimum amount of
electricity. Payments for electricity sold under the power purchase contracts
are generally made to the Joint Ventures on a monthly basis.
 
     All of the power purchase contracts have tariff formulas and other pricing
provisions which are designed, based on the minimum take obligation of the power
purchaser, to be sufficient to pay the operating costs and financing costs of
the project and to enable AES Chigen to realize a return on its investment.
These tariff formulas are indexed to hedge against US dollar and Renminbi
exchange rate fluctuation risks relating to repayment of principal and interest
on debt and the conversion to US dollars of AES Chigen's profits. In the event
of a change in law which increases the Joint Ventures' costs, the power purchase
contracts typically require an adjustment to the tariff formulas in order to
pass through such increased costs.
 
     The Joint Ventures in all cases except one -- Cili Misty Mountain -- have
entered, or it is anticipated will enter, into dispatch contracts with the
relevant dispatching entity for its power plant pursuant to which the dispatcher
has agreed or plans to agree to dispatch the power plant at least the annual
minimum amount of hours required under the power purchase contract. For the one
case, the power purchaser, which is also the dispatcher, is responsible for
dispatching the power plant.
 
     Each of the joint venture contracts for the projects described in this
section may be terminated early, including on account of a termination of the
relevant power purchase contract. In all cases except one -- Jiaozuo Aluminum
Power -- in the event of an early termination of a power purchase contract which
results from a default of a power purchaser, AES Chigen is entitled under the
applicable power purchase contract to receive from the power purchaser payment
intended to compensate the Joint Venture for the return it would have received
had the power purchase contract continued to the end of its term.
 
     In two cases -- Yangchun Sun Spring and Wuxi Tin Hill -- projects directly
managed by the Joint Ventures have been successfully constructed on time. For
three of AES Chigen's projects currently under construction -- Jiaozuo Aluminum
Power, Cili Misty Mountain, and Chengdu Lotus City -- the respective Joint
Venture also directly manages the construction of the power plant. In these
instances the Joint Venture has entered into arrangements with various
construction and equipment procurement consortiums, including established
foreign equipment manufacturers, in which certain responsibilities relating to
construction and procurement have been allocated to members of the consortium.
For the remaining three projects currently under construction, each relevant
Joint Venture has entered into a fixed price, fixed schedule construction
contract, one of which is a turnkey arrangement. In all of the projects
described in this section, the electrical transmission and interconnection
facilities are being financed by interest bearing loans from the Joint Venture
to the relevant power purchaser who is responsible for constructing, owning,
operating and maintaining the
 
                                       55
<PAGE>   63
 
facilities. In the case of Wuhu Grassy Lake, Hefei Prosperity Lake and Chengdu
Lotus City, the power purchasers have also agreed in the power purchase
contracts to begin making payments under their respective power purchase
contracts on a specified date if the power plant is completed, but cannot
deliver electricity due to a delay in completing the transmission and
interconnection facilities.
 
     Five of the eight power plants are or will be operated directly by the
Joint Ventures -- Cili Misty Mountain, Wuxi Tin Hill, Aixi Heart River, Jiaozuo
Aluminum Power and Chengdu Lotus City -- and three -- Yangchun Sun Spring, Hefei
Prosperity Lake and Wuhu Grassy Lake -- will be operated by the relevant power
purchasers. Fuel for most of the power plants has been contracted for under long
term fuel supply contracts with fuel suppliers or will be supplied by the power
purchasers. In the latter case, the relevant power purchaser is not excused from
its payment obligations under its power purchase contract if it is unable to
provide fuel to the power plant.
 
     The power projects which are currently in operation or under construction
have obtained insurance coverage for property loss and damage (including damage
arising from natural calamities) and third party liability. Most force majeure
risks which can be categorized as natural calamities are covered under the
insurance policies. The Joint Ventures are in all cases relieved of their
obligation to deliver electricity under their power purchase contracts for the
power plants described in this section in the event of force majeure, including
an event of force majeure caused by the PRC Government. In the case of all
projects, except Wuhu Grassy Lake and Hefei Prosperity Lake, the power purchaser
is not relieved of its obligations under its applicable power purchase contract,
including the obligation to make payments to AES Chigen in such circumstances.
In these two projects, the power purchaser is relieved of its obligation to
purchase the minimum amount of electric power under its respective power
purchase contract during periods in which the power plant is unable to generate
electric power due to events of force majeure, including events of force majeure
caused by the PRC Government.
 
     In the case of all of the power plants described in this section, AES
Chigen and its Joint Venture partners have applied for and received PRC
approvals for the project and for the establishment of the related foreign
investment enterprise. In the case of two power plants -- Jiaozuo Aluminum Power
and Wuhu Grassy Lake -- the power plants have received project approvals at the
Central Government level from the State Planning Commission and have received
approvals from MOFTEC for the establishment of their related Joint Venture. Each
of the remaining six power plants has received its project approval and foreign
investment approval from provincial and local government entities.
 
     Two of AES Chigen's power plants currently in operation or under
construction -- Wuxi Tin Hill and Hefei Prosperity Lake -- have been structured
as multiple projects and Joint Ventures, with each project and Joint Venture
having a total investment not exceeding the $30 million approval authority
threshold generally applicable to provincial and local governments. In two other
cases -- Aixi Heart River and Chengdu Lotus City -- AES Chigen's projects and
Joint Ventures have obtained local government approvals on the basis of
anticipated total investments which did not exceed $30 million at the time the
approvals were obtained, but will, when construction is completed, exceed the
$30 million approval threshold. See "Risk Factors -- AES Chigen Risk
Factors -- Risks Related to AES Chigen's Business -- Government Approval
Processes."
 
     The tariff formulas set forth in the power purchase contracts of the Joint
Ventures described in this section have been either approved or confirmed by the
relevant provincial and local government pricing bureaus responsible for
reviewing such tariffs.
 
     All of the joint venture contracts and project contracts of the Joint
Ventures are governed by PRC law. Some of the joint venture contracts provide
for arbitration of a dispute arising under the joint venture contracts in
locations outside of the PRC, while some provide for arbitration in the PRC by
PRC arbitration bodies. Most of the project contracts, including the power
purchase contracts, provide for arbitration of disputes in the PRC by PRC
arbitration bodies.
 
JIAOZUO ALUMINUM POWER
 
     The Power Plant.  The Jiaozuo Aluminum Power power plant is a 2 x 125 MW
coal-fired power plant located adjacent to the Jiaozuo Aluminum Mill ("Jiaozuo
Mill") aluminum production mills in Jiaozuo, Henan Province. Construction of the
power plant commenced in the first quarter of 1995. The first unit of the
 
                                       56
<PAGE>   64
 
power plant is scheduled to commence commercial operation by the second quarter
of 1997. The second unit is scheduled to commence commercial operation in the
second quarter of 1998.
 
     Joint Venture.  The Jiaozuo Aluminum Power power plant is owned by Jiaozuo
Wan Fang Power Company Ltd. ("Jiaozuo Wan Fang"), a 23-year cooperative Joint
Venture formed by Jiaozuo Mill and a wholly-owned subsidiary of AES Chigen.
Pursuant to the joint venture contract AES Chigen is entitled to recover its
registered capital (equity) during the term of the Joint Venture. AES Chigen, as
the majority shareholder of Jiaozuo Wan Fang, is entitled to appoint four of the
six members of the board of directors of the Joint Venture, including the
chairman of the board and the general manager. Pursuant to a co-development
agreement, an entity unaffiliated with AES Chigen is entitled to no more than
ten percent of AES Chigen's equity distributions from Jiaozuo Wan Fang.
 
     Financing.  The approved total investment in Jiaozuo Wan Fang is $151.3
million. The Joint Venture's approved registered capital is $53.7 million. As of
November 30, 1996, it is estimated that the total cost of Jiaozuo Aluminum Power
will be approximately $161.3 million. Any difference between the approved total
investment and the actual total cost will be funded by additional equity or
loans to be contributed pro rata by the shareholders of Jiaozuo Wan Fang. AES
Chigen has committed to contribute $37.6 million to the registered capital of
the Joint Venture. Jiaozuo Mill has committed to contribute $16.1 million in
land use rights and certain fixed assets to the registered capital of the Joint
Venture.
 
     Power Purchase.  Jiaozuo Wan Fang and Jiaozuo Mill have entered into a
23-year power purchase contract effective April 26, 1996. Pursuant to the power
purchase contract, Jiaozuo Mill has agreed to purchase from Jiaozuo Wan Fang at
least 5,500 hours each calendar year at 75 MW up to the amount required to
operate Jiaozuo Mill's aluminum mill. Any remaining electricity from the power
plant, but no less than 5,500 hours at 155 MW, will be purchased by the Henan
Electric Power Corporation ("Henan Power") under a 23-year power purchase
contract between Jiaozuo Wan Fang and Henan Power. Both power purchase contracts
require the purchasers to pay for a minimum amount of electricity generated
every calendar year and to compensate the Joint Venture for any shortfalls in
purchases of such minimum amount based on the most recent approved tariff for
power less fuel costs. Both power purchase contracts allow the Joint Venture to
adjust the minimum amount of electricity required to be purchased by the power
purchasers and Jiaozuo Mill may request the Joint Venture to adjust the minimum
amount of electricity required to be purchased by Jiaozuo Mill, in all cases,
upon prior notice.
 
     There are no specific provisions regarding liquidated damages upon early
termination of either power purchase contract. However, in the case of early
termination due to Henan Power's default, Henan Power is obligated under the
power purchase contract, to the extent permitted by law, to transmit electricity
generated by the Joint Venture's power plant to any entity designated by the
Joint Venture which is interconnected with Henan Power.
 
     Construction.  Jiaozuo Wan Fang is directly managing the construction of
the power plant. Jiaozuo Wan Fang has hired the Henan Power Design Institute for
the project design and Henan Provincial No. 1 Power Construction Company and
Henan Provincial No. 2 Power Construction Company as contractors for civil and
installation work. Although no heat rate (the term "heat rate" refers to a power
plant's thermal efficiency), output or completion guarantees are being provided
by the contractors, these two contractors have built a number of similar power
plants. In addition, more than 100 of such 125 MW units have been delivered by
their manufacturer, Shanghai Electric Corporation ("Shanghai Electric"), which
is providing a limited two-year warranty of the units. An independent
engineering company, Bechtel Power Corporation, has been retained by Jiaozuo Wan
Fang to manage scheduling and procurement. The construction risk in the case of
this project is also mitigated by the tariff formula set forth in the power
purchase contract which provides for an increase in the tariff payable by the
power purchaser sufficient to compensate the Joint Venture for any reduction in
heat rate and capacity resulting from the contractor's performance failure.
 
     Interconnection and Dispatch.  The interconnection facilities are being
constructed by Henan Power. Jiaozuo Wan Fang has agreed to provide a loan in the
amount of approximately $9.9 million to Henan Power for the design and
construction of the interconnection facilities. When in commercial operation,
the power plant will be dispatched by Henan Power. The Joint Venture is required
under its dispatch contract with Henan Power to cause the power plant to
maintain an annual minimum availability. If this annual minimum
 
                                       57
<PAGE>   65
 
availability is not met, the minimum amount required to be purchased by Henan
Power may be reduced proportionately.
 
     Fuel.  Jiaozuo Wan Fang plans to enter into one-year fuel supply contracts
for the purchase of anthracite coal from mines in Jiaozuo and mines located
approximately 120 kilometers from the power plant. The price for coal is to be
negotiated periodically with the mine owners. Jiaozuo Wan Fang will arrange for
the transportation of the coal by truck to the power plant.
 
     Operation.  Jiaozuo Wan Fang will operate the power plant.

vice chairmen and the deputy general manager responsible for supervising the
operation and maintenance of the power plant.
 
     Financing.  The approved total investment in the Joint Venture is $118.4
million. The Joint Venture's approved registered capital is $30.0 million. The
Joint Venture partners of Wuhu Shaoda have committed to contribute their
registered capital according to their respective ownership interests as follows:
(i) CPI, $13.5 million (45%), (ii) AES Chigen, $7.5 million (25%), (iii) Anhui
Liyuan, $6.0 million (20%) and (iv) Wuhu Energy, $3.0 million (10%). As of
November 30, 1996, the estimated total cost of this project was in line with the
approved total investment. The difference between the total investment and the
registered capital of Wuhu Shaoda has been financed through a bank facility and
shareholder loans arranged by the Joint Venture partners. Wuhu Shaoda has
entered into a $65.0 million term loan facility (the "Term Loan") with a
syndicate of lenders. The first drawdown of the Term Loan took place in August
1996. The Term Loan is to be repaid in 11 successive semi-annual installments
beginning April 22, 1998. In addition to the Term Loan, AES Chigen has committed
to provide an $18.0 million subordinated loan (the "AES Loan") and Anhui Liyuan
has committed to provide up to $4.6 million and Wuhu Energy has committed to
provide up to $2.3 million in subordinated shareholders' loans to the Joint
Venture. AES Chigen has guaranteed to the lenders of the Term Loan certain
obligations of its wholly-owned subsidiary under the joint venture contract,
including with respect to the funding of the AES Loan and certain other
liabilities which, in the aggregate, do not exceed $6.0 million.
 
     Dividend payments are subject to certain restrictions under the Term Loan.
No dividend distributions by the Joint Venture are permitted if certain debt
service coverage ratios are not met.
 
     Power Purchase.  The electric power from the power plant will be purchased
by Anhui Provincial Electric Power Corporation ("Anhui Power") pursuant to a
20-year operation and offtake contract dated as of July 5, 1996, between Wuhu
Shaoda and Anhui Power. Under the power purchase contract, Anhui Power has
agreed to purchase a minimum amount of electricity at a price calculated based
upon an agreed tariff formula. In the event that the power plant fails to
generate electricity for a period in excess of that permitted for maintenance
and repair in the operation and offtake contract and such failure is a result of
force majeure or Wuhu Shaoda's failure to perform its obligations under the
operation and offtake contract, the minimum amount required to be purchased by
Anhui Power may be reduced in proportion to such excess shutdown period,
provided that in no event will the electricity payments to be made under the
operation and offtake contract be reduced below the amount necessary to allow
Wuhu Shaoda to pay all applicable financing costs under the Term Loan, the AES
Loan and the other shareholder loans.
 
                                       58
<PAGE>   66

constructed pursuant to a fixed price construction contract between Wuhu Shaoda
and Anhui Power. Pursuant to the construction contract, Anhui Power is the
principal contractor and is responsible for the timely and successful completion
of the power plant. Anhui Power has sub-contracted the design, construction,
installation and commissioning work to several of its subsidiaries. Anhui Power
is eligible for a bonus in the event of early completion of a unit. If the power
plant is not completed by August 1997, Anhui Power is required by the operation
and offtake contract nonetheless to commence purchases of the minimum amount of
electricity. The construction contract does not obligate Anhui Power to provide
guarantees of heat rate or capacity. However, in the event that Anhui Power
fails to achieve the design heat rate or nameplate capacity of the power plant,
the tariff formula set forth in the operation and offtake contract increases the
tariff payable by Anhui Power in a manner that compensates Wuhu Shaoda for the
reduction in heat rate and capacity. An independent engineering company, Stone
and Webster Management Consultants, has been retained by the lenders of the Term
Loan to monitor construction.
 
     Interconnection and Dispatch.  The power plant is interconnected to the
Anhui power grid and is subject to dispatch by Anhui Power pursuant to an
interconnection contract between Wuhu Shaoda and Anhui Power.

less fuel costs. Pursuant to the power purchase contract, the minimum amount of
electricity which Xishan Office is required to purchase from the Joint Ventures
may be reduced by the number of peak time shutdown hours which exceeds an agreed
number of hours permitted for outages related to the power plant.
 
     During 1996, Xishan Office did not purchase the required minimum amount of
electricity under the power purchase contract and, accordingly, is required to
compensate the Joint Venture for the shortfall. The parties have a disagreement
over the amount of the required minimum take. Xishan Office has paid 88% of the
amount the Joint Venture believes is due but disputes the balance. The parties
also have a disagreement over the amount of construction-period interest that is
due in respect of shareholders loans provided to the Joint Venture by its
respective partners. AES Chigen believes that the amount at issue in these
disagreements is not material to the financial results of AES Chigen.
 
     Construction.  The construction of the power plant has been managed by the
Joint Ventures. The gas turbines were supplied by United Technologies Inc.
("United Technologies"). Pursuant to a maintenance contract with the Joint
Ventures, United Technologies will provide 10 years of service and maintenance
for the gas turbines. The balance of the plant has been provided by Chinese
manufacturers.
 
     Interconnection and Dispatch.  The interconnection facilities were
completed in March 1996 and the power plant is connected to the East China Power
Grid. The power plant is currently dispatched under an agreement between Wuxi
AES-CAREC and Xishan Power Supply Bureau. A dispatch contract between the Joint

<PAGE>   69
 
     Financing.  The approved total investment in the Joint Venture is $30.4
million ($30.0 million based on the Renminbi yuan to US dollar exchange rate at
the time the approval was granted). The Joint Venture's approved registered
capital is $12.1 million. As of November 30, 1996, it is estimated that the
total cost of Aixi Heart River will be approximately $39.1 million. AES Chigen
has committed to contribute $8.5 million to the registered capital of Fuling
Aixi and Banxi Colliery has committed to contribute $3.6 million to the Joint
Venture's registered capital. Pursuant to the construction and term loan
agreement with Fuling Aixi, AES Chigen has committed to provide a loan in the
principal amount of up to $23.5 million to Fuling Aixi. Any difference between
the estimated total cost and the committed shareholder loan and approved
registered capital will be funded by additional equity contributed pro rata by
the shareholders.
 
     Power Purchase.  Electricity generated by the power plant will be sold to
Sichuan Fuling Power Company ("Sichuan Power") under a 25-year power purchase
contract. The power purchase contract requires Sichuan Power to purchase a
minimum of 270 GWh of electricity per calendar year. In the event that Sichuan
Power fails in any calendar year to purchase such minimum amount, Sichuan Power
is required by the power purchase contract to make payment for any shortfall at
the then current power price less fuel costs. Pursuant to the power purchase
contract, if Fuling Aixi fails to deliver electricity to Sichuan Power by the
construction completion date specified in the construction contract, it is
obligated to pay a penalty to Sichuan Power for each day of delay.

Shanghai Electric to construct the power plant. Certain critical components of
the equipment of the power plant (including the coal fluidized bed boilers and
their design) are being supplied by Pyropower, Inc. ("Pyropower") pursuant to a
supply contract between Shanghai Electric and Pyropower. The balance of the
plant is being provided by Chinese manufacturers. Shanghai Electric will provide
a one-year warranty of its work. If Shanghai Electric fails to complete
construction of the power plant by the guaranteed completion date, the
contractor will be required to pay liquidated damages to Fuling Aixi for each
day of delay in an amount sufficient to compensate the Joint Venture for
penalties due to Sichuan Power under the power purchase contract for delayed
commercial operation of the power plant. Under the construction contract,
Shanghai Electric has guaranteed all the performance specifications of the power
plant, including output, heat rate and emissions. If the power plant fails to
achieve the performance specifications, Shanghai Electric will be obligated to
pay liquidated performance damages to Fuling Aixi.
 
     Interconnection and Dispatch.  Sichuan Power is responsible for
construction, and has guaranteed the completion, of the interconnection facility
by the power plant's performance testing date. If a delay in the completion of
the interconnection facility results in delays in commencement of the commercial
operation of the power plant, Sichuan Power is obligated to pay Fuling Aixi a
penalty for each day of delay. The dispatcher of the power plant has agreed to
dispatch the power plant at 100% of its operational capacity during peak hours
and at 75% of its operational capacity during off-peak hours.
 
     Fuel.  Fuling Aixi has entered into a 25-year coal supply contract with
Banxi Colliery. Any increase in the price of coal to be paid by Fuling Aixi will
only become effective under the coal supply contract when the price of
electricity payable by Sichuan Power has been increased to reflect the increased
coal cost. The occurrence of a force majeure event will not excuse Banxi
Colliery's obligations under the coal supply contract. Banxi Colliery is also
obligated to supply coal to the power plant in the case of non-payment by Fuling
Aixi for such coal if such non-payment was caused by a failure of Sichuan Power
to make a payment to Fuling Aixi under the power purchase contract. If the coal
supply contract is terminated by Fuling Aixi on account of Banxi Colliery's
default, Banxi Colliery is required to pay a termination charge to Fuling Aixi.
 
     Operation.  Fuling Aixi will operate the power plant.

Huaxi Electric Power (Group) Shareholding Company Ltd. ("Huaxi") and CAREC. AES
Chigen is entitled to appoint three members of the nine-member board of
directors of Chengdu AES-Kaihua and the general manager.
 
     Financing.  The approved total investment in the Joint Venture is $29.8
million. The Joint Venture's approved registered capital is $11.9 million. As of
November 30, 1996, it is estimated that the total cost of Chengdu Lotus City
will be approximately $37.4 million. AES Chigen has committed to contribute $4.2
million to the registered capital of Chengdu AES-Kaihua. AES Chigen's joint
venture partners have committed to contribute the following amounts to the
registered capital of the Joint Venture: Huaxi has committed to contribute $4.2
million and CAREC has committed to contribute $3.6 million. AES Chigen, Huaxi
and CAREC have entered into support contracts with Chengdu AES-Kaihua pursuant
to which they have committed to arrange loans for Chengdu AES-Kaihua in the
principal amount of $25.3 million to fund the difference between their
registered capital contributions and the estimated total cost of the Joint
Venture.
 
     Power Purchase.  Electricity generated by the power plant is to be sold to
Huaxi under a 15-year power purchase contract. The power purchase contract
requires Huaxi to purchase, in each calendar year, 3,000 hours of electric power
based on the net station capacity of the power plant declared by Chengdu
AES-Kaihua to be available in such year. If Huaxi fails, for any reason
(including due to the failure of the interconnection facilities or natural gas
pipeline to be completed), to accept electric power which is made available by
Chengdu AES-Kaihua, Huaxi is required by the power purchase contract to pay
Chengdu AES-Kaihua for the electricity made available at the then current power
price less fuel costs.
 
     The tariff payable by Huaxi under the power purchase contract is
established annually by the board of directors of Chengdu AES-Kaihua in
accordance with a budget which estimates the costs of generating the minimum
amount in the following year. The estimated power price becomes the price
payable by Huaxi in such following year after its approval by the Chengdu
pricing bureau. Any differences between the estimated power price and the actual
costs per kWh incurred by Chengdu AES-Kaihua are recovered each year by means of
a true-up mechanism.
 
     Construction.  Chengdu AES-Kaihua has entered into a construction contract
with CAREC to construct the power plant. The principal equipment for the power
plant, the gas turbine generator sets, is being provided to Chengdu AES-Kaihua
pursuant to a supply contract between CAREC and United Technologies. All
performance guarantees (including damages for failures to meet heat rate and
output guarantees) and warranties of United Technologies under the supply
contract have been assigned by CAREC to Chengdu AES-Kaihua. The balance of the
plant is being provided by Chinese manufacturers. An independent engineering
company, Duke/Fluor Daniel International, has been retained by the Joint Venture
to manage scheduling and to ensure equipment performance compliance.
 
     Interconnection and Dispatch.  The interconnection facility is to be
constructed by Huaxi. Chengdu AES-Kaihua has agreed to provide Huaxi with a loan
of RMB Y 15.0 million for the construction of the interconnection facilities.
The Joint Venture has entered into a dispatch contract with the Sichuan Dispatch
Center, pursuant to which the dispatcher of the power plant has agreed to
dispatch the power plant.
 
     Fuel.  Chengdu AES-Kaihua has entered into a 15-year gas supply contract
with Huachuan Petroleum & Natural Gas Exploration and Development Company
("Huachuan") for the supply of natural gas to the power plant. The gas supply
contract requires Huachuan to provide a minimum annual quantity of natural gas
to the Chengdu facility which meets certain specifications at a price set by the
Chengdu municipal pricing bureau. Any increase in the price of gas to be paid by
Chengdu AES-Kaihua will only become effective under the gas supply contract when
the price of electricity payable by Huaxi under its power purchase contract has
been increased to reflect the increased cost. If Huachuan fails, on any
occasion, to deliver gas in the quantities and specifications required by
Chengdu AES-Kaihua, Huachuan is obligated under the gas supply contract to
indemnify Chengdu AES-Kaihua for the total revenue lost by Chengdu AES-Kaihua
due to such failure. Huachuan is also obligated to continue supplying natural
gas to the power plant in the case of non-payment by Chengdu AES-Kaihua for such
natural gas if such non-payment was caused by a failure of Huaxi to make payment
to Chengdu AES-Kaihua under the power purchase contract.
 
                                       63
<PAGE>   71
 
     Chengdu AES-Kaihua may terminate the gas supply contract for Huachuan's
breach of contract, including its failure to deliver natural gas. If Chengdu
AES-Kaihua terminates the contract, Huachuan must pay a termination charge
similar to the termination charge payable under the power purchase contract. If
Huachuan pays this termination charge, the termination charge for which Huaxi
would be liable under the power purchase contract as a consequence of Huachuan's
default is not applicable. Upon any such payment, Chengdu AES-Kaihua is
obligated to transfer the power plant and related gas interconnection facility
to Huachuan.
 
     Operation.  Chengdu AES-Kaihua will operate the power plant.
 
CILI MISTY MOUNTAIN
 
     The Power Plant.  The Cili Misty Mountain power plant, located in Cili
County, Hunan Province, consists of a 5.2 MW hydroelectric generating unit
("unit 1"), and two 10.5 MW hydroelectric generating units ("unit 2" and "unit
3"). Unit 1, the original power plant, has been in commercial operation since
1979. Unit 2 went into commercial operation in May 1996 and unit 3 went into
commercial operation in February 1997.
 
     Joint Venture.  The Cili Misty Mountain power plant is owned by Hunan
Xiangci-AES Hydro Power Company Ltd. ("Xiangci-AES"), a 25-year Joint Venture
formed by Hunan Cili Electric Power Company ("Cili Electric Power") and AES
Chigen. AES Chigen appoints three of the five members of the Joint Venture's
board of directors, and appoints the general manager.
 
     Financing.  The approved total investment and approved registered capital
of Xiangci-AES is $14.7 million. AES Chigen contributed $7.5 million to the
registered capital of Xiangci-AES and Cili Electric Power contributed all of the
assets of the previously existing and operating unit 1 and all of the equipment
and materials purchased for the construction of unit 2 and unit 3 which, at the
time of AES Chigen's equity contribution to Xiangci-AES, were being incorporated
into the project by Cili Electric Power. All liabilities of the power plant
incurred prior to the establishment of Xiangci-AES are the sole obligation of
Cili Electric Power. As of November 30, 1996, the estimated total cost of this
project was in line with the approved total investment.
 
     Power Purchase.  Electricity generated by the power plant is sold by
Xiangci-AES to Cili Electric Power pursuant to a 25-year power purchase
contract. Cili Electric Power is required by the terms of the power purchase
contract to purchase all of the electricity generated by the power plant and to
use its best efforts to purchase electricity in excess of 120 GWh. Since the
power plant utilizes hydro power, the extent to which the power plant is able to
generate electric power depends upon the flow of river water. Due to a drought
in the area, the power plant was not able to generate 120 GWh in 1996.
Additionally, Cili Electric Power has indicated to the Joint Venture that load
growth in Cili County is likely to be less than anticipated in the near future.
Because the power plant is located in an area served by an isolated transmission
grid, the Joint Venture is planning to incur additional costs to build a 36
kilometer low voltage transmission line to connect the power plant with the
Hunan provincial grid and the larger market it serves. The power purchase
contract provides that payment for electricity purchased by Cili Electric Power
is based on a tariff which is the higher of a minimum rate and a market rate.
 
     Construction.  Pursuant to the terms of the joint venture contract, all of
the capital contributed by AES Chigen to Xiangci-AES is to be used to complete
construction of unit 2 and unit 3. Cili Electric Power was responsible under the
terms of the joint venture contract for completing the construction of unit 2
and unit 3. Work on unit 2 and unit 3 began in September 1991, with completion
originally targeted for June 1995. Construction of unit 2 was completed and it
began commercial operation in May 1996. However, due to problems with
installation and an equipment defect, construction of unit 3 was delayed.
Xiangci-AES has entered into an agreement with Cili Electric Power pursuant to
which the Joint Venture has directly assumed the work of completing the
construction of unit 3. Cili Electric Power has been discharged from any further
obligation to complete the power plant.
 
     Interconnection and Dispatch.  The power plant is interconnected to the
Cili County power grid. The power plant is dispatched by Cili Electric Power.
 
                                       64

     Operation.  Xiangci-AES operates the power plant.
 
YANGCHUN SUN SPRING
 
     The Power Plant.  The Yangchun Sun Spring power plant, located in Yangchun,
Guangdong Province, consists of one existing 8.6 MW diesel engine generating
facility which was constructed prior to AES Chigen's involvement, and another
6.5 MW Stork-Wartsila diesel engine generating facility which commenced
commercial operation in April 1996.
 
     Joint Venture.  Yangchun Sun Spring is owned by Yangchun Fuyang Diesel
Engine Power Co. Ltd. ("Yangchun Fuyang"), a 12-year cooperative Joint Venture
formed by Yangchun Municipal Power Supply Company ("Yangchun Power Supply"),
Shenzhen Futian Gas Turbine Power Co., Ltd. ("Shenzhen Futian") and a
wholly-owned subsidiary of AES Chigen. AES Chigen has the right to appoint one
of the four members of the board of directors of the Joint Venture.
 
     Financing.  AES Chigen and Shenzhen Futian each has contributed $2.3
million in cash to Yangchun Fuyang for their respective 25% ownership interests.
Yangchun Power Supply has contributed land use rights, and all the fixed assets
of the existing plant and all the equipment and materials purchased for the unit
then under construction as its registered capital for a 50% ownership interest
in Yangchun Fuyang.
 
     Power Purchase.  The electricity generated from the power plant is
purchased by Yangchun Municipal Power Supply Bureau ("Yangchun Power Bureau")
under a 12.5-year power purchase contract. The Yangchun Power Bureau is required
by the power purchase contract to purchase at least 34.4 GWh each year
commencing on January 1, 1995 and at least 58 GWh each year after December 31,
1995. The Yangchun Power Bureau is required to pay for such minimum amounts of
electricity even if it does not or cannot purchase such minimum amounts. The
Yangchun Power Bureau's payment obligation is secured by a pledge of the annual
profit from a 13 MW hydro power plant owned by the Yangchun City People's
Government.
 
     Construction and Management.  Yangchun Fuyang and Yangchun Power Supply
have entered into a 12.5-year construction and management contract. The contract
calls for Yangchun Power Supply to assume full responsibility for the operation
and maintenance of the power plant on behalf of Yangchun Fuyang in compliance
with the power purchase contract, and to supply fuel to the power plant. The
construction and management contract provides for scheduled distributions to AES
Chigen and Shenzhen Futian beginning on March 31, 1996 and continuing on a
semi-annual basis for the remainder of the contract term. The amounts are
adjusted if the foreign exchange rate between the U.S. dollar and Renminbi
exceeds or falls below specified thresholds. Yangchun Power Supply has pledged
its registered capital interest in Yangchun Fuyang as security for its
obligations to make scheduled distributions to AES Chigen and Shenzhen Futian
under the construction and management contract.
 
     Interconnection and Dispatch.  The power plant is interconnected to the
Yangchun municipal power grid. The power plant is dispatched by the Yangchun
Electric Dispatch Office pursuant to a dispatch contract between the Joint
Venture and the Yangchun Power Bureau.
 
     Fuel.  Fuel oil required for the power plant is supplied by Yangchun Power
Supply.
 
     Operation.  Yangchun Fuyang operates the power plant.
 
DESCRIPTION OF THE POTENTIAL PROJECTS
 
     This section contains descriptions of projects, other than current
projects, for which AES Chigen has signed a joint venture contract. However, in
none of the following projects has AES Chigen funded its equity contribution to
the registered capital of the joint venture. After the Amalgamation, the ability
of AES Chigen to make investments in the potential projects would be
substantially limited by the AES Debt Covenants. See "AES Chigen's Relationship
with AES -- Material Effects of the Amalgamation."
 
     Under PRC law, joint venture contracts only become effective after issuance
of certain required government approvals. Some of AES Chigen's joint venture
contracts and project contracts for projects in development are also subject to
the satisfaction or waiver of certain significant contractual conditions
precedent. The conditions precedent specified in such contracts must be
satisfied before AES Chigen will contribute to the registered capital of the
applicable joint venture. These conditions precedent may include the
 
                                       65
<PAGE>   73
 
negotiation and execution of further substantial project contracts or the
receipt of certain government approvals.
 
     Some of the required government approvals have not been obtained for each
of the projects described in this section and receipt of such approvals is not
certain. In addition, substantial uncertainties exist with regard to the ability
of the parties to the joint venture contracts and other project contracts to
satisfy the conditions precedent in those documents. Certain of these conditions
involve subjective determinations by one or more parties enabling the parties,
by the terms of the contracts, to exercise considerable discretion in making
such determinations. No assurances can be given that governmental approvals will
be received, conditions precedent will be satisfied, or that the joint ventures
described in this section will be funded.
 
     The projects described in this section are at various stages of negotiation
and discussion. AES Chigen and PRC Government authorities, including power
bureaus, pricing bureaus, industrial customers and other third parties, must
still reach agreement on a number of commercial and technical issues. There can
be no certainty that the parties to these negotiations will reach agreement with
AES Chigen and that the projects described in this section will be completed.
Moreover, the final terms of the contracts relating to these projects may differ
materially from the terms described below, and the terms may be revised even
after a joint venture contract or other project contract has been signed or
becomes effective. AES Chigen may also decide from time to time to change its
investment strategies regarding development of the projects described in this
section. Among other things, AES Chigen may increase the levels of registered
capital contemplated for such projects. Furthermore, AES Chigen may in the
future be unable to, or elect not to, proceed with one or more, or any, of the
projects described in this section. AES Chigen in the past has signed a number
of joint venture contracts for projects that it is no longer pursuing.
 
     Yangcheng Sun City.  The Yangcheng Sun City power plant is a 6 x 350 MW
coal-fired power plant to be located near Yangcheng, Shanxi Province. The
Yangcheng Sun City power plant is to be owned by Yangcheng International Power
Generating Company Ltd. ("Yangcheng International Power"), a 20-year cooperative
joint venture formed by North China Electric Power Group Corporation ("North
China Power"), Jiangsu Province Investment Corporation ("Jiangsu Investment"),
Shanxi Energy Enterprise (Group) Company ("Shanxi Energy"), Shanxi Provincial
Power Company ("Shanxi Power"), Jiangsu Provincial Power Company ("Jiangsu
Power") and AES Chigen.
 
     The approved total investment in Yangcheng International Power is
approximately $1.6 billion. The approved registered capital of Yangcheng
International Power is 25% of the total investment, equal to $392.9 million. The
respective ownership interests of the shareholders in Yangcheng International
Power are as follows: AES Chigen-25%, North China Power-25%, Jiangsu
Investment-20%, Shanxi Energy-16%, Shanxi Power-10% and Jiangsu Power-4%. Hence,
AES Chigen's registered capital contribution will be approximately $98.2
million. The difference between the total investment and the total registered
capital of the joint venture is expected to be financed through debt arranged or
guaranteed by the Chinese parties. It is anticipated that export credit agency
loan guarantees from the Export-Import Bank of the United States and Hermes
Kreditversicherungs Aktiengesellschaft of approximately $800 million will be
provided to Yangcheng International Power. The export credit agency loan
guarantees are expected to be supported by guarantees from the Construction Bank
of China.
 
     Pursuant to the joint venture contract, AES Chigen is entitled to appoint
two members of the nine-member board of directors of Yangcheng International
Power, one of the three vice chairmen, and a deputy general manager of the power
plant.
 
     Preliminary work on the site has begun. Equipment supply contracts were
executed in Beijing in September 1996 with Siemens Ltd., which will supply the
turbines and generators, and with Foster Wheeler Energy International, which
will supply the boilers. Shanxi Power has been selected as the turnkey
contractor, and negotiations are currently underway with Shanxi Power on the
engineering, procurement and construction contract. It is anticipated that the
power plant will require five years to be completed.
 
     The power plant will primarily utilize local sources of low-cost anthracite
coal. The coal is available from several coal mines owned and operated by Shanxi
provincial government entities located within 30 kilometers of the power plant
site. Long-term fuel supply contract negotiations with Shanxi Provincial Coal
Sales and
 
                                       66
<PAGE>   74
 
Transportation Company will commence in the near future. It is anticipated that
the project will also be operated by Yangcheng International Power.
 
     Electric power from the plant will be transmitted over a 730 kilometer
transmission line to Jiangsu Power in Jiangsu Province, on the eastern coast of
China. The construction of the transmission line is not part of the investment
of the joint venture. It will be constructed and financed by the Chinese
shareholders in Yangcheng International Power pursuant to a separate
arrangement.
 
     Following State Planning Commission approval of the project feasibility
study in March 1996, negotiations commenced on the principal project agreements.
 
     The ability of AES Chigen to make an investment in the Yangcheng Sun City
project following the Amalgamation is contingent on, among other things, the
consent of AES Chigen's partners in such project and the approval of the
relevant PRC Government authorities. See "AES Chigen's Relationship with AES --
Material Effects of the Amalgamation."
 
OTHER POTENTIAL PROJECTS
 
     Tianjin TEDA.  The Tianjin TEDA power project, to be located in the Tianjin
Economic-Technological Development Area near Tianjin, is a 100 MW coal-fired
cogeneration project consisting of 3 x 220 ton circulating fluidized bed boilers
and 2 x 50 MW steam turbine units. The first phase will consist of one boiler
and one steam turbine. The Tianjin TEDA power plant is to be owned by the
Tianjin TEDA AES Power Company Ltd., a 20-year cooperative joint venture formed
by a wholly owned subsidiary of AES Chigen and the Tianjin Economic Development
Corporation ("Tianjin Development"). Total investment in the joint venture is
expected to be approximately $95 million. Registered capital of the joint
venture is expected to be 40% of the total investment. Unless third-party debt
can be arranged, the parties will contribute shareholder loans representing 60%
of the total investment. AES Chigen has a 70% ownership interest and Tianjin
Development has a 30% ownership interest in the joint venture. Applications for
approval of the project have been made to the State Planning Commission and
MOFTEC. The joint venture contract will become effective upon satisfaction of
certain conditions precedent.
 
     Nanpu Southern Delta.  The Nanpu Southern Delta power plant, to be located
in Huian County Fujian Province, is a 700 MW coal-fired power plant consisting
of 2 x 350 units. The Nanpu Southern Delta power plant is to be owned by the
Fujian Nanpu Power Company Limited, a 19-year cooperative joint venture formed
by AES Chigen, the Fujian Provincial Power Bureau ("Fujian Power") and CPI. The
total investment in the joint venture is expected to be approximately $600
million and the registered capital is expected to be approximately $150 million.
The project costs in excess of the registered capital are expected to be
financed through limited-recourse project financing. CPI and Fujian Power have
committed to obtain, on behalf of the project company, all necessary approvals,
including those from the State Planning Commission, MOFTEC and SAFE. Negotiation
of the power purchase contract and other project documents has commenced. The
project has received its initial project approval from the State Planning
Commission, and Fujian Power has commenced the preliminary design work for the
power plant at its own cost.
 
     The ability of AES Chigen to make an investment in the Nanpu Southern Delta
project following the Amalgamation is contingent on, among other things, the
consent of AES Chigen's partners in such project and the approval of the
relevant PRC Government authorities. See "AES Chigen's Relationship with AES --
Material Effects of the Amalgamation."
 
                              RECENT DEVELOPMENTS
 
AES
 
     In February 1997, AES entered into a definitive agreement to acquire the
international assets (inclusive of approximately $42 million of net monetized
assets) of Destec Energy, Inc. ("Destec"), a large independent energy producer
with headquarters in Houston, Texas, at a total price to AES of $407 million,
which price is subject to adjustment to reflect net cash flow between the
international assets of Destec and the rest of Destec from January 1, 1997 to
the closing date. AES and NGC Corporation ("NGC") were selected as the winning
bidders in an auction for all of Destec at a total acquisition price of $1.27
billion. For its share of the
 
                                       67
<PAGE>   75
 
acquisition price, NGC has agreed to acquire Destec's domestic energy and other
businesses. Destec's international assets to be acquired by AES include
ownership interests in the following five electric generating plants (with
ownership percentages in parentheses): (i) a 110 MW gas-fired combined cycle
plant in Kingston, Canada (50 percent), (ii) a 405 MW gas-fired combined cycle
plant in Terneuzen, Netherlands (50 percent), (iii) a 140 MW gas-fired simple
cycle plant in Cornwall, England (100 percent), (iv) a 235 MW oil-fired simple
cycle plant in Santo Domingo, Dominican Republic (99 percent); and (v) a 1600 MW
coal-fired plant in Victoria, Australia (20 percent). The acquisition by AES of
Destec's international assets also includes all of Destec's non-U.S.
developmental stage power projects, including projects in Taiwan, England,
Germany, the Philippines, Australia and Colombia. A number of risks are
associated with this acquisition including those relating to the closing of the
transaction, the receipt of government approvals and other consents, financing,
operation and maintenance, construction and environmental risk.
 
     In February 1997, AES announced that its subsidiary, AES Electric Ltd.,
raised $184 million of non-recourse project financing, underwritten solely by
The Industrial Bank of Japan, Limited, for its 230 MW gas-fired combined cycle
facility in Barry, South Wales, United Kingdom. The Barry facility will sell
electricity into the national electricity market in the United Kingdom, and is
expected to be operational by the second quarter of 1998. AES began construction
of the Barry facility in October 1996. Substantial risks to the successful
completion of this project exist, including those relating to governmental
approvals, the demand for and price of electricity in the United Kingdom
national electricity market, financing, construction and permitting. There can
be no assurance that this project will be completed.
 
     In February 1997, AES announced the execution by subsidiaries of AES of
three power purchase agreements (the "PPAs"), for an aggregate generating
capacity of at least 457 MWs, with GPU Energy, the energy services and delivery
business of GPU, Inc., a public utility holding company. AES plans to build a
720 MW natural gas-fired, combined cycle facility in Pennsylvania to sell power
under the PPAs beginning in 2000 and to sell power to other potential
purchasers. Between March and July 1996, subsidiaries of AES acquired the right
to negotiate the PPAs from other independent power producers for a net aggregate
cost of approximately $28 million. GPU Energy is required to reimburse AES for
substantially all its initial net investment if the project does not receive the
requisite regulatory approvals and permits. The project is subject to a number
of risks not covered by the reimbursement obligations, including those related
to financing, construction and contract compliance, and there can be no
assurance that the project will be completed successfully.
 
     On January 30, 1997, AES issued a press release reporting revenues of $835
million, net income of $125 million and net income per share of $1.62 for the
fiscal year ended December 31, 1996.
 
     In January 1997, AES, through a subsidiary, completed the purchase of an
additional 13% of Tiszai Eromu Rt., an electric generation company in Hungary
consisting of three power plants totaling 1,281 MWs of gross capacity (1,115 MW
net) and a coal mine, from employee pension plans at a cost of $17 million,
bringing AES's total equity interest in Tiszai Eromu Rt. to 93.8%. In July 1996,
AES acquired its initial 80.8% of Tiszai Eromu Rt. at a cost of $110 million.
The plants consist of (i) the Tisza II facility, an 860 MW oil and natural
gas-fired facility that sells electricity under a contract that has an initial
term ending in 2010, (ii) the Tiszapalkonya facility, a 250 MW coal-fired
facility that sells electricity under a contract that has an initial term ending
in 2001, and (iii) the Borsod facility, a 171 MW coal-fired facility that sells
electricity under a contract that has an initial term ending in 2001. AES also
has the right to develop an additional 150-200 MW coal-fired electric generating
facility. The Borsod facility, the coal mine and the right to develop the
additional facility are 67.9% owned by Tiszai Eromu Rt. through its principal
subsidiary. The remaining 32.1% is owned by the Hungarian government. AES plans
to purchase an additional 2% of Tiszai Eromu Rt. from the Hungarian government
at a cost of $3 million. AES has also recently completed a voluntary severance
program which achieved a reduction of 56% of the workforce (or approximately
2,500 people) at a cost of approximately $23 million. Substantial risks
associated with these plants exist, however, including those relating to the
successful completion of power sales arrangements with the Hungarian government,
plant operation and maintenance, construction difficulties in respect of the
undeveloped facility, plant refurbishment, environmental risk, political risk,
repatriation of earnings and currency inconvertibility.
 
                                       68

     In January 1997, a joint venture company led by a subsidiary of AES was
selected as the winning bidder to build, own and operate a 484 MW (net)
gas-fired combined cycle power plant in the City of Merida, Yucatan, Mexico.
 
     In January 1997, AES acquired an additional 2.4% of the voting interest in
Light Servicos de Electricidade, S.A. ("Light"), a vertically integrated
electric utility in the state of Rio de Janeiro, Brazil, bringing its total
equity interest in Light to 13.75%. In December 1996, a subsidiary of AES
completed a $167.5 million syndicated bank financing related to its equity
ownership of Light (which at the time was 11.35%). Under the terms of the
financing, a wholly-owned subsidiary of AES pledged the shares of Light owned by
it as collateral for the loan. The proceeds of the financing were used to repay
a portion of the debt incurred in the original acquisition of Light.
 
     In August 1996, AES, together with its partner, acquired a 4,000 MW
mine-mouth, coal-fired power facility in Kazakhstan. AES owns at least 70% of
the joint venture. The facility sells electricity to the government-owned
distribution company under a 35 year power sales contract. Due to economic
difficulties over the last 10 years, the facility has experienced a reduction in
performance and has operated at a capacity factor of approximately 20%. AES has
agreed to upgrade all aspects of the power station, and increase the capacity to
63% over a five year period (assuming that the purchaser performs its
obligations under the power sales contract). There can be no assurance that AES
will be able to make the required upgrades. Through December 31, 1996,
approximately $35 million has been billed under the power sales contract for
electricity delivered by AES and the purchaser has paid approximately $5
million. There can be no assurance as to the ultimate collectibility of amounts
owed to AES as of December 31, 1996 or additional amounts related to future
deliveries by AES of electricity under the power sales contract. Other
substantial risks associated with this plant exist, including those relating to
operations and maintenance, construction, refurbishment, political risk,
repatriation of earnings and currency inconvertibility.
 
AES CHIGEN
 
     On January 31, 1997, AES Chigen issued a press release reporting revenues
of $9.2 million, net income of $2.1 million and net income per share of $0.26
for the fiscal year ended November 30, 1996.
 
     On December 19, 1996, AES Chigen completed a $180 million public offering
of its 10 1/8% Notes due December 2006 (the "2006 Notes") and received net
proceeds of approximately $173.9 million. Pursuant to the terms of the indenture
under which the 2006 Notes were issued (the "Indenture"), AES Chigen was
required to deposit approximately $27.1 million in an interim reserve account to
make interest payments on the 2006 Notes through June 15, 1998, and
approximately $9.1 million in a debt payment reserve. The 2006 Notes are
redeemable at the option of AES Chigen on or after December 15, 2001. The

CERTAIN LITIGATION IN RESPECT OF THE AMALGAMATION
 
     On November 22, 1996, an action was filed against AES in the Court of
Chancery of the State of Delaware in and for New Castle County, by a holder of
750 shares of AES Chigen Class A Common Stock, individually and on behalf of a
purported class of public shareholders of the approximately 8.2 million
outstanding shares of AES Chigen Class A Common Stock. The complaint seeks
preliminarily and permanently to enjoin AES from acquiring the outstanding
shares of AES Chigen which it does not already own. In addition, the complaint
seeks unspecified damages, including attorneys' fees and costs.
 
     AES Chigen is not named in the suit. Plaintiff's allegations state that
AES, as the controlling shareholder of AES Chigen, breached its fiduciary duties
to treat the plaintiff class with entire fairness in connection with AES's
execution of an agreement with AES Chigen to acquire the outstanding AES Chigen
Class A Common Stock at an allegedly grossly inadequate price.
 
     The parties have entered into a stipulation extending, until March 24,
1997, AES's time to answer, move or otherwise plead to the complaint and answer
or object to plaintiff's pending document production request. Plaintiff has the
right to move for an order requiring an earlier response. AES has informed AES
Chigen that it believes that it has meritorious defenses to the lawsuit and
intends to defend against it vigorously. The parties to the Amalgamation
Agreement intend to proceed with the Amalgamation, subject to shareholder
approval and the satisfaction of the other conditions contained in the
Amalgamation Agreement, unless enjoined.

                        DESCRIPTION OF AES CAPITAL STOCK
 
     The authorized capital stock of AES consists of 100,000,000 shares of AES
Common Stock and 1,000,000 shares of AES Preferred Stock.
 
AES COMMON STOCK
 
     As of February 1, 1997, there were 77,437,564 shares of AES Common Stock
outstanding which were held of record by 743 stockholders. Assuming that there
are 8,171,268 shares of AES Chigen Class A Common Stock outstanding at the
Effective Time (which assumes that no outstanding options on AES Chigen Class A
Common Stock are exercised) and that the Exchange Ratio is 0.29, there will be
approximately 79,817,545 shares of AES Common Stock outstanding after giving
effect to the issuance of shares of AES Common Stock in the Amalgamation.
 
     The holders of AES Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding AES Preferred Stock, the holders of AES Common
Stock are entitled to receive ratably such dividends, if any, as may be declared
from time to time by the Board of Directors of AES out of funds legally
available therefor. In the event of liquidation, dissolution or winding up of
AES, the holders of AES Common Stock are entitled to share ratably in all assets
remaining after payment of liabilities, subject to prior distribution rights of
the AES Preferred Stock, if any, then outstanding. The AES Common Stock has no
preemptive or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the AES Common Stock. All
outstanding shares of AES Common Stock are fully paid and non-assessable and
shares of AES Common Stock offered hereby will be fully paid and non-assessable.
 
AES PREFERRED STOCK
 
     The Board of Directors of AES has the authority to issue the AES Preferred
Stock in one or more classes or series and to fix the rights, preferences,
privileges and restrictions thereof, including dividend rights, dividend rates,
conversion rights, voting rights, terms of redemption, redemption prices,
liquidation preferences and the number of shares constituting any class or
series or the designation of such class of series, without further vote or
action by the stockholders. AES Preferred Stock, if issued, will not be entitled
to any preemptive or similar rights. The issuance of AES Preferred Stock may
have the effect of delaying, deferring or preventing a change in control of AES
without further action by the stockholders and may adversely affect the voting
and other rights of the holders of AES Common Stock. At present, AES has no
plans to issue any of the AES Preferred Stock.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for AES Common Stock is First Chicago
Trust Company of New York.
 
DESCRIPTION OF CERTAIN PROVISIONS OF
AES'S CERTIFICATE OF INCORPORATION AND BY-LAWS
 
     AES's Certificate of Incorporation and By-Laws contain several provisions
that may make the acquisition of control of AES by means of a tender offer, open
market purchases, a proxy fight or otherwise more difficult. Set forth below is
a description of certain of these provisions in AES's Certificate of
Incorporation and By-Laws.
 
     SPECIAL MEETINGS OF STOCKHOLDERS.  AES's By-Laws provide that, unless
otherwise prescribed by law, special meetings of stockholders may be called by a
resolution adopted by a majority of the entire Board of Directors, the Chairman
of the Board or the President and shall be called by the Chairman of the Board
or the President upon written request of stockholders owning at least 10% of
stock entitled to vote. Only such business as shall be specified in the notice
of stockholders of the special meeting shall be considered.
 
                                       78
<PAGE>   86
 
     STOCKHOLDER NOMINATION OF DIRECTORS.  AES's By-Laws contain a procedure for
stockholder nomination of directors. The By-Laws provide that any record owner
of stock entitled to be voted generally in the election of directors may
nominate one or more persons for election as a director at a stockholders
meeting only if written notice is given to the Secretary of AES of the intent to
make such nomination. The notice must be given, with respect to an annual
meeting, not later than 90 days in advance of such annual meeting and with
respect to a special meeting, not later than the close of business on the
seventh day following the earlier of (a) the date on which notice of such
special meeting is first given to stockholders and (b) the date on which a
public announcement of such meeting is first made. Each notice must include (i)
the name and address of each stockholder who intends to appear in person or by
proxy to make the nomination and of the person or persons to be nominated; (ii)
a description of all arrangements or understandings between the stockholder and
each nominee and any other person or persons (naming them) pursuant to which the
nomination is to be made by the stockholder; (iii) such other information
regarding each nominee proposed by such stockholder as would have been included
in a proxy statement filed pursuant to Rule 14a-8 under the Exchange Act; and
(iv) the consent of each nominee to serve if elected. The presiding officer of
the meeting may refuse to acknowledge the nomination of any person not made in
compliance with this procedure.
 
     The procedure for stockholder nomination of directors described above may
have the effect of precluding a nomination for election of directors at a
particular meeting if the required procedure is not followed.
 
     ELIMINATION OF LIABILITY; INDEMNIFICATION.  Except as set forth below,
AES's Certificate of Incorporation eliminates the liability of AES's directors
to AES or its stockholders for monetary damages resulting from breaches of their
fiduciary duties as directors. Directors remain liable for breaches of their
duty of loyalty to AES or its stockholders, as well as for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law and transactions from which a director derives improper personal benefit.
AES's Certificate of Incorporation also does not absolve directors of liability
under Section 174 of the Delaware General Corporation Law (the "GCL"), which
makes directors personally liable for unlawful dividends or unlawful stock
repurchases or redemptions if the unlawful conduct is willful or results from
negligence.
 
     Under AES's By-Laws, and in accordance with Section 145 of the GCL, AES
shall indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than any action
or suit by or in the right of AES to procure a judgment in its favor, a
"derivative action") by reason of the fact that such person is or was a director
or officer of or employed by AES, or is or was serving in such capacity or as an
agent at the request of AES for another entity, to the full extent authorized by
Delaware law, against expenses (including, but not limited to, attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection with the defense or settlement of such action, suit or proceeding
if such person acted in good faith and in a manner the person reasonably
believed to be in or not opposed to the best interests of AES, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe was
unlawful. AES shall indemnify persons in a derivative action under the same
conditions, except that no indemnification is permitted without judicial
approval if the person is adjudged to be liable to AES in the performance of his
or her duty. Agents of AES may be similarly indemnified at the discretion of the
Board of Directors.
 
     Under Section 145 of the GCL, a similar standard of care is applicable in
the case of derivative actions, except that indemnification only extends to
expenses (including attorneys' fees) incurred in connection with the defense of
settlement of such an action and then, where the person is adjudged to be liable
to AES, only if and to the extent that the Court of Chancery of the State of
Delaware or the court in which such action was brought determines that such
person is fairly and reasonably entitled to such indemnity and only for such
expenses as the court shall deem proper.
 
     Pursuant to AES's By-Laws, a person eligible for indemnification may have
the expenses incurred in connection with any matter described above paid in
advance of a final disposition by AES. However, such advances will only be made
upon the delivery of an undertaking by or on behalf of the indemnified person to
repay all amounts so advanced if it is ultimately determined that such person is
not entitled to indemnification.

     In addition, under AES's By-Laws, AES may purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of
AES or of another corporation against any liability asserted against and
incurred by such person in such capacity, or arising out of the person's status
as such whether or not AES would have the power or the obligation to indemnify
such person against such liability under the provisions of AES By-Laws.
 
                       AES CHIGEN'S RELATIONSHIP WITH AES
 
     AES owns 7,500,000 shares of AES Chigen Class B Common Stock, representing
approximately 48% of AES Chigen's outstanding shares. As a result of such
ownership, AES has the right to elect one-half of AES Chigen's Board of
Directors. AES Chigen and AES have entered into a number of agreements, which
are described below. These agreements were not negotiated on an arm's-length
basis. Any amendment of these agreements or waiver by AES Chigen of its rights
under these agreements would have to be approved by a majority of the Class A
Directors. Also set forth below is a description of AES's current intentions
with respect to AES Chigen and the China power market assuming the Amalgamation
is consummated.
 
STOCK PURCHASE AND SHAREHOLDER'S AGREEMENT
 
     AES Chigen and AES entered into the Stock Purchase and Shareholder's
Agreement pursuant to which AES Chigen issued to AES 7,500,000 shares of AES
Chigen Class B Common Stock in consideration of: (i) the investment by AES of
$50 million in AES Chigen; (ii) the assignment (subject to obtaining necessary
third-party consents) to AES Chigen of AES's direct or indirect interests in all
letters of intent and preliminary agreements with PRC government entities and
other third parties in respect of the development of electric power generation
projects in China; and (iii) AES's agreement not to compete, and to cause each
of its controlled subsidiaries not to compete, with AES Chigen in China for at
least ten years. The Stock Purchase and Shareholder's Agreement provides that
until the occurrence of certain events AES shall not acquire any shares of the
AES Chigen Class A Common Stock without obtaining a waiver from AES Chigen
approved by a majority of the Class A Directors. The Stock Purchase and
Shareholder's Agreement also provides that until the fifth anniversary of the
date of the Services Agreement (as defined below) AES will apply the after-tax
proceeds of all performance fees received by AES with respect to AES Chigen's
projects to the purchase of additional shares of AES Chigen Class B Common
Stock, subject to certain exceptions. AES has not received any such performance
fees pursuant to the Services Agreement. See " -- Services Agreement." The Stock
Purchase and Shareholder's Agreement will be terminated if the Amalgamation is
consummated.
 
SERVICES AGREEMENT
 
     Pursuant to a Services Agreement dated December 29, 1993 between AES Chigen
and AES (the "Services Agreement"), AES provides to AES Chigen project
development services, construction management services and operations and
maintenance services necessary for AES Chigen to perform its obligations in
connection with the development, construction, ownership, acquisition,
maintenance and operation of electric power generation projects in the PRC.
 
     As compensation for its services under the Services Agreement, AES receives
a payment equal to the salaries and certain benefits of persons performing
services on behalf of AES under the Services Agreement, plus 45% thereof to
cover corporate overhead and similar indirect costs. AES also receives 50% of
any development fee, construction success fee or operations and maintenance
performance fee received by AES Chigen in respect of projects for which AES has
performed services. Because these arrangements were not negotiated on an
arm's-length basis, it is possible that AES Chigen could obtain similar services
on more favorable terms from third parties.
 
     AES has received payments under the Services Agreement of approximately
$2.0 million, $4.1 million and $2.3 million in 1994, 1995 and 1996,
respectively.
 
                                       80
<PAGE>   88
 
     The Services Agreement has an initial term of five years. The Services
Agreement will be automatically renewed for three additional five-year terms
unless AES Chigen elects not to renew the Services Agreement by written notice
to AES given not less than three months prior to the end of the initial term or
either of the first two renewal terms. AES expects to continue to provide
services to AES Chigen under the Services Agreement after the Amalgamation so
long as AES Chigen continues to develop, construct and operate power facilities
in China.
 
NON-COMPETITION AND NON-DISCLOSURE AGREEMENT
 
     As part of the consideration for issuance to AES of 7,500,000 shares of AES
Chigen Class B Common Stock, AES and AES Chigen entered into a Non-Competition
and Non-Disclosure Agreement, dated as of December 29, 1993 and amended and
restated as of February 1, 1994 (the "Non-Competition Agreement"). The
Non-Competition Agreement provides that AES will not, and will not permit any
subsidiary to, develop, construct, own, manage, operate, control, invest in,
lend to, or acquire an interest in, or otherwise engage or participate in any
electric power generation project in China, for a period equal to the greater of
(i) ten years and (ii) three years after the earlier of (a) termination or
non-renewal of the Services Agreement for any reason and (b) the permitted sale,
conveyance or transfer by AES of all of its shares of AES Chigen Class B Common
Stock to an unaffiliated party or parties. The Non-Competition Agreement will be
terminated if the Amalgamation is consummated.
 
AES AFFILIATES' AGREEMENTS
 
     Roger W. Sant, the Chairman of the Board and a director of AES, and Dennis
W. Bakke, the President, Chief Executive Officer and a director of AES, and each
other director and executive officer of AES (the "AES Affiliates"), have entered
into agreements with AES Chigen (the "AES Affiliates' Agreements") pursuant to
which each AES Affiliate has agreed that until such date as all of the shares of
AES Chigen Class B Common Stock have been converted to shares of AES Chigen
Class A Common Stock, such AES Affiliate will not acquire, offer to acquire, or
agree to acquire any shares of AES Chigen Class A Common Stock or rights or
options to acquire any shares of AES Chigen Class A Common Stock, or make or in
any way participate in any solicitation of proxies to vote or seek to advise,
encourage or influence any person or entity with respect to the voting of any
AES Chigen Class A Common Stock. This restriction does not apply to any such
action if any person (other than such AES Affiliate, AES or a subsidiary of AES)
publicly announces or proposes to the Board of Directors or management of AES
Chigen any tender or exchange offer, merger, consolidation, solicitation of
proxies or similar transaction involving the AES Chigen Class A Common Stock, or
any sale, lease, exchange, mortgage, pledge, transfer or other disposition (in
one transaction or series of transactions) by AES Chigen, any subsidiary of AES
Chigen or any joint venture in which AES Chigen or any subsidiary invests which
involves aggregate consideration equal to 50% or more of the aggregate book
value of all the assets of AES Chigen determined on a consolidated basis. The
AES Affiliate's Agreement of Thomas I. Unterberg, a director of AES and of AES
Chigen, provides that the foregoing restrictions will not restrict any
market-making or investment banking activities of Unterberg Harris, of which he
is a Managing Director.
 
     Waivers of restrictions on purchasing AES Chigen Class A Common Stock under
the AES Affiliates' Agreement entered into by Paul T. Hanrahan, President and
Chief Executive Officer of AES Chigen, were granted in 1995 to permit Mr.
Hanrahan to purchase 2,000 shares of AES Chigen Class A Common Stock.
 
     Each AES Affiliates' Agreement will have no further relevance if the
Amalgamation is consummated, because all AES Chigen Common Stock will be owned
by AES.
 
DUAL STATUS OF OFFICERS
 
     Messrs. Sant and Bakke, in addition to serving as Chairman and Vice
Chairman of AES Chigen, respectively, serve as executive officers of AES. Mr.
Hanrahan devotes substantially all of his time serving as President and Chief
Executive Officer of AES Chigen, but continues as a Vice President of AES and
devotes some of his time to AES's activities in Asia. Mr. Safford devotes
substantially all of his time serving as Vice
 
                                       81
<PAGE>   89
 
President, Chief Financial Officer and Secretary of AES Chigen but continues to
work for AES, which, from time to time, requires him to devote a portion of his
time to other AES matters. Messrs. Hall and Yeager devote substantially all of
their time serving as Executive Vice President and Vice President of AES Chigen,
respectively, but also continue to work for AES, which, from time to time,
requires them to devote a portion of their time to other AES matters. While
Messrs. Hanrahan, Safford and Hall are expected to devote substantially all of
their time to AES Chigen's business, AES Chigen and AES have not established any
fixed allocation of their time. AES Chigen and AES acknowledge that the dual
status of the aforesaid persons with AES Chigen and AES may, from time to time,
require attention by an individual or individuals to matters for AES rather than
AES Chigen's business in the future. In the event that such circumstances arise,
AES Chigen intends to shift responsibilities of other officers, or to appoint
additional officers, and to take such other action as may be necessary to avoid
an adverse effect on AES Chigen's business. Furthermore, AES has agreed that it
will adopt similar staffing strategies to avoid, to the extent possible,
conflicting demands on such officers.
 
MATERIAL EFFECTS OF THE AMALGAMATION
 
     After the Amalgamation, AES Chigen will be subject to the covenants (the
"AES Debt Covenants") contained in AES's debt instruments applicable to
subsidiaries, including the documents governing its 10-1/4% Subordinated Notes
due 2006, 9 3/4% Senior Subordinated Notes due 2000 and $425 million credit
facility due 1999. If the Amalgamation occurs, the material limitations
applicable to AES Chigen will include those described below.
 
     Limitation on Subsidiary Investments and Mergers.  Under the AES Debt
Covenants, AES may not permit any subsidiary with a direct or indirect interest
in a power generation facility (as defined in the relevant agreements) to make
any investment in, or to consolidate or merge with, any other entity with a
direct or indirect interest in any other power generation facility or other
business.
 
     Immediately prior to the expected consummation of the Amalgamation, AES
Chigen intends to contribute the net proceeds of the 2006 Notes remaining after
the funding of an interim reserve account and a debt service reserve account,
along with certain of its existing funds, to its subsidiaries to provide funding
for potential projects and other future projects, as well as additional funding
for current projects. See "Recent Developments -- AES Chigen." It is anticipated
that these amounts will not in the aggregate be more than approximately $95
million. Under the AES Debt Covenants, as a general matter, after exhaustion of
these amounts, no additional AES Chigen funds would be available to fund
investment in additional power projects or to fund the capital requirements and
construction cost overruns for current projects. As a consequence, opportunities
for investment, along with the associated risks, that would otherwise be
available to AES Chigen may instead be taken by other investors, including AES.
See " -- AES's Plans for AES Chigen and the China Market." Additional capital
requirements for AES Chigen-invested projects would have to be funded by other
parties, including AES, which would result in a dilution of AES Chigen's
interest in any such project. In addition, due to the application of the AES
Debt Covenants, cash flow generated from projects would not be permitted to be
invested in any other project. As a result, to the extent these funds are not
required to pay expenses incurred by AES Chigen, they may accumulate over time.
AES Chigen is permitted, pursuant to the terms of the Indenture under which the
2006 Notes were issued, to pay a portion of such funds as dividends to AES,
provided that AES Chigen satisfies certain conditions.
 
     In addition, under the AES Debt Covenants, investment could not be made in
a project directly by AES Chigen (as opposed to through one of its
subsidiaries). Accordingly, prior to the Amalgamation, AES Chigen intends to
transfer its interests in certain potential projects, such as Yangcheng Sun
City, Jinhua Golden China and Nanpu Southern Delta, to wholly-owned subsidiaries
of AES Chigen. In the case of each of these projects, the consent of AES
Chigen's partners in such project and the examination and approval of the
relevant PRC government authority are required to effect the transfers of AES
Chigen's interest. There can be no assurance that such consents and approvals
will be obtained in order to permit investments to be made in these projects
following the Amalgamation.
 
                                       82
<PAGE>   90
 
     Limitation on Indebtedness.  Under the AES Debt Covenants, AES Chigen and
its subsidiaries would be effectively prohibited from incurring additional
indebtedness (as defined in the relevant instruments), except that a subsidiary
would under some circumstances be permitted to incur indebtedness for the
purpose of financing a power project as long as such indebtedness did not have
recourse to AES, AES Chigen or another subsidiary.
 
     Asset Sales.  Both the AES Debt Covenants and the covenant contained in the
Indenture relating to the 2006 Notes applicable to AES Chigen require the
repayment or purchase of indebtedness under specified circumstances involving
asset dispositions. Insofar as separate repayments are required at the AES and
AES Chigen levels with respect to a single asset sale, this covenant may tend to
cause AES Chigen not to make an asset sale under circumstances where it
otherwise would.
 
     Limitation on Investment Following Project Default.  Under the AES Debt
Covenants, an AES subsidiary is not permitted to make an investment in a project
company following the occurrence of a condition permitting the acceleration of
indebtedness relating to the project or any failure to pay such indebtedness at
its final maturity.
 
AES'S PLANS FOR AES CHIGEN AND THE CHINA MARKET
 
     Although, as discussed under "Material Effects of the Amalgamation",
certain AES Debt Covenants will limit the operations of AES Chigen if the
Amalgamation is consummated, AES nevertheless may continue to pursue the
development of power generation facilities in China through other subsidiaries
and structures within the restrictions imposed by the AES Debt Covenants. AES
will consider the allocation of its capital and resources to the development of
power generation facilities in such countries, including China and many others,
which in AES's view offer the most attractive returns and opportunities.
 
              COMPARISON OF SHAREHOLDERS' AND STOCKHOLDERS' RIGHTS
 
GENERAL
 
     As a result of the Amalgamation, holders of shares of AES Chigen Class A
Common Stock will become stockholders of AES and the rights of all such former
AES Chigen shareholders will thereafter be governed by AES's Certificate of
Incorporation, AES's By-Laws and the GCL. The rights of the holders of shares of
AES Chigen Class A Common Stock are presently governed by the Memorandum of
Association of AES Chigen (the "AES Chigen Charter"), the Bye-Laws of AES Chigen
(the "AES Chigen Bye-Laws") and the Companies Act. The following summary sets
forth the material differences among the rights of the stockholders of AES and
the shareholders of AES Chigen and sets forth the material differences between
AES's Certificate of Incorporation and the AES Chigen Charter, AES's By-Laws and
the AES Chigen Bye-Laws and the GCL and the Companies Act. This summary is
qualified by reference to the full text of each of such documents, the GCL and
the Companies Act. For information as to how such documents may be obtained, see
"Available Information."
 
COMPARISON OF BERMUDA AND DELAWARE CORPORATE LAW
 
     The Companies Act, under which AES Chigen is incorporated, differs in
certain material respects from the provisions of the GCL. Set forth below is a
summary of such differences. The following statements are summaries, and do not
purport to deal with all aspects of Bermuda or Delaware law that may be relevant
to AES Chigen and its shareholders.
 
VOTING RIGHTS WITH RESPECT TO EXTRAORDINARY CORPORATE TRANSACTIONS
 
     BERMUDA.  Bermuda law permits an amalgamation between two or more Bermuda
companies (or between one or more Bermuda exempted companies and one or more
foreign corporations) subject, unless the bye-laws otherwise provide, to
obtaining a majority vote of three fourths of the shareholders of each such
company present and voting in person or by proxy at a meeting called for the
purpose. AES Chigen's Bye-
 
                                       83
<PAGE>   91
 
Laws provide for a lesser vote. See "The Class A Meeting and the Special
Meeting." "Short form" amalgamations are permitted between a holding company and
one or more of its wholly-owned subsidiary companies or between two or more
wholly-owned subsidiary companies of the same holding company subject to
approval of the amalgamation by a resolution of the directors of each
amalgamating company.
 
     DELAWARE.  Approval of mergers and consolidations and of sales, leases or
exchanges of all or substantially all of the property or assets of a corporation
requires the approval of the holders of a majority of the outstanding shares
entitled to vote, except that no vote of stockholders of the corporation
surviving a merger is necessary if: (i) the merger does not amend the
certificate of incorporation of the corporation, (ii) each outstanding share
immediately prior to the merger is to be an identical share after the merger,
and (iii) either no common stock of the corporation and no securities or
obligations convertible into common stock are to be issued in the merger, or the
common stock to be issued in the merger plus that initially issuable on
conversion of other securities issued in the merger does not exceed 20% of the
common stock of the corporation immediately before the merger.
 
APPRAISAL RIGHTS
 
     BERMUDA.  Under Bermuda law, a dissenting shareholder of a company
participating in an amalgamation (other than an amalgamation between a company
and its wholly-owned subsidiary or between two or more subsidiaries of the same
holding company) may, in certain circumstances, receive cash in the amount of
the fair value of his shares (as determined by a court), in lieu of the
consideration he would otherwise receive in any such transaction.
 
     DELAWARE.  Stockholders are entitled to demand appraisal of their shares in
the case of a merger or a consolidation, except where (i) they are stockholders
of the surviving company and the merger did not require their approval under the
GCL or (ii) the corporation's shares are either listed on a national securities
exchange or NASDAQ or held of record by more than 2,000 stockholders as of the
record date for the vote on such merger or consolidation. Appraisal rights are
available in either (i) or (ii) above, however, if the stockholders are required
by the terms of the merger or consolidation to accept any consideration other
than (a) stock of the corporation surviving or resulting from the merger or
consolidation, (b) shares of stock of another corporation which at the effective
date of the merger or consolidation will be either listed on a national
securities exchange or NASDAQ or held of record by more than 2,000 stockholders,
(c) cash in lieu of fractional shares or (d) any combination of the foregoing.
Appraisal rights are not available in the case of a sale, lease, exchange or
other disposition by a company of all or substantially all of its property and
assets.
 
DERIVATIVE SUITS
 
     BERMUDA.  The Bermuda courts ordinarily would be expected to follow English
precedent, which would permit a shareholder to commence a derivative action in
the name of the company to remedy a wrong done to the company only (a) where the
act complained of is alleged to be beyond the corporate power of the company or
illegal; (b) where the act complained of is alleged to constitute a fraud
against the minority shareholders by those controlling the company; provided,
that the majority shareholders have used their controlling position to prevent
the company from taking action against the wrongdoers; (c) where an act requires
approval by a greater percentage of the company's shareholders than actually
approved it; or (d) where there is an absolute necessity to waive the general
rule that a shareholder may not bring such an action in order that there not be
a violation of the company's memorandum of association or bye-laws. The actions
summarized above are generally recognized as exceptions to the rule in Foss v.
Harbottle, under which only the company could initiate an action.
 
     There is a statutory remedy under section 111 of the Companies Act, which
provides that a shareholder may seek redress of the court as long as he can
establish that the company's affairs are being conducted, or have been
conducted, in a manner oppressive or prejudicial to the interests of some part
of the shareholders, including himself. The court would also have to be
satisfied that to wind up the company would unfairly prejudice that part of the
shareholders, but otherwise the facts would justify the making of a winding-up
order on the ground that it was just and equitable that the company should be
wound up. If the court is satisfied on
 
                                       84
<PAGE>   92
 
these two grounds it can make such order as it thinks fit, whether for
regulating the conduct of the company's affairs in future, or for the purchase
of the shares of any shareholders of the company by other shareholders of the
company or by the company. This remedy has not yet been interpreted by the
Bermuda courts and therefore it is not known to what extent the court will
exercise its discretion. However, the term "oppressive" as used in the previous
statute in relation to minority interests has been interpreted restrictively by
the English courts in Jermyn Street Turkish Baths, Ltd. There is also provision
under section 161(g) of the Companies Act for the court to wind up a company if
it is of the opinion that it is just and equitable that the company should be so
wound up. However, the grounds for making such an order are relatively limited.
 
     DELAWARE.  The plaintiff must have been a stockholder of the corporation at
the time of the transaction of which he complains or his stock thereafter must
have devolved upon him by operation of law.
 
SPECIAL MEETINGS OF STOCKHOLDERS
 
     BERMUDA.  Under Bermuda law, an annual general meeting must be held once
every calendar year; a special meeting of shareholders may be convened by the
Directors at any time and must be convened upon the requisition of shareholders
holding not less than one-tenth of the paid up capital of the company carrying
the right to vote at general meetings.
 
     DELAWARE.  Stockholders generally do not have the right to call meetings of
stockholders unless such right is granted in the certificate of incorporation or
by-laws. However, if a corporation fails to hold its annual meeting within a
period of 30 days after the date designated therefor, or if no date has been
designated for a period of 13 months after its last annual meeting, the Delaware
Court of Chancery may order a meeting to be held upon the application of a
stockholder. The AES By-Laws provide that special meetings of the stockholders
shall be called at the request in writing of stockholders owning ten percent
(10%) or more of the outstanding voting stock. See " -- Charter and By-Law
Provisions -- Special Meetings of Stockholders."
 
ACTION BY CONSENT
 
     BERMUDA.  Action by written consent of shareholders is permitted where the
written resolution is signed by all of the shareholders who would be entitled to
attend and vote at a meeting, with the exception of a resolution to remove an
auditor or a director before the expiration of his term of office.
 
     DELAWARE.  Unless otherwise specified in a corporation's certificate of
incorporation, action required or permitted to be taken by stockholders at an
annual or special meeting may be taken by stockholders without a meeting,
without notice and without a vote, if consents, in writing, setting forth the
action, are signed by stockholders with not less than the minimum number of
votes that would be necessary to authorize the action at a meeting. All consents
must be dated. No consent is effective unless, within 60 days of the earliest
dated consent delivered to the corporation, written consents signed by a
sufficient number of holders to take action are delivered to the corporation.
 
AMENDMENTS TO CHARTER
 
     BERMUDA.  Amendments to the memorandum of association of a Bermuda company
must be submitted to a general meeting of the shareholders and shall be
effective only to the extent approved by the shareholders at such meeting and,
except for the alteration of share capital, by the Bermuda Minister of Finance.
Amendments to the bye-laws of a Bermuda company must be submitted to a general
meeting of the shareholders and shall be effective only to the extent approved
by the shareholders at such meeting.
 
     DELAWARE.  Amendments to the certificate of incorporation require the
affirmative vote of the holders of a majority of the outstanding shares entitled
to vote thereon or such greater vote as is provided for in the certificate of
incorporation; a provision in the certificate of incorporation requiring the
vote of a greater number or proportion of the directors or of the holders of any
class of stock than is required by the GCL may not be amended, altered or
repealed except by such greater vote. See " -- Charter and By-Law Provisions --
Amendments to Charter and By-Laws."
 
                                       85
<PAGE>   93
 
TENDER OFFER STATUTES
 
     BERMUDA.  Bermuda does not currently have a tender offer statute. However,
Bermuda law provides that where an offer is made for shares in a company by
another company and, within four months of the offer, the holders of not less
than 90% in value of the shares which are the subject of the offer accept, the
offeror may by notice, given within two months after the expiration of the said
four months, require the dissenting shareholders to transfer their shares on the
terms of the offer. Dissenting shareholders may apply to a court within one
month of such notice objecting to the transfer and the court may give such order
as it thinks fit.
 
     DELAWARE.  Generally, Section 203 of the GCL prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the time of the
transaction in which the person became an interested stockholder, unless (i)
prior to such time, the transaction or the business combination is approved by
the board of directors of the corporation, (ii) upon consummation of the
transaction which resulted in the stockholder becoming an interested
stockholder, the interested stockholder owned at least 85% of the outstanding
voting stock (excluding for purposes of determining the number of shares
outstanding, shares owned by directors who are also officers and by certain
employee plans) or (iii) on or after such time the business combination is
approved by the board and by the affirmative vote of a least 66 2/3% of the
outstanding voting stock which is not owned by the interested stockholder. Such
"business combinations" include mergers, assets sales and other transactions
resulting in a financial benefit to the interested stockholder. An "interested
stockholder" is a person who, together with affiliates and associates, owns (or
within three years, did own) 15% or more of the corporation's voting stock.
 
LIMITATIONS ON DIRECTOR LIABILITY
 
     BERMUDA.  Under Bermuda law, a director must observe the statutory duty of
care which requires such director to act honestly and in good faith with a view
to the best interests of the company and exercise the care, diligence and skill
that a reasonably prudent person would exercise in comparable circumstances.
Directors are also subject to common law fiduciary duties which require
directors to act in what they reasonably believe to be the best interests of the
company and for a proper purpose. Bermuda law renders void any provision in the
bye-laws or any contract between a company and any such director exempting him
from or indemnifying him against any liability in respect of any fraud or
dishonesty of which he may be guilty in relation to the company. The AES Chigen
Bye-Laws contain certain provisions limiting the liability of directors as
permitted under Bermuda law. See " -- Charter and By-Law
Provisions -- Limitations on Director Liability."
 
     DELAWARE.  Under Delaware law, a corporation may include in its certificate
of incorporation a provision eliminating or limiting the liability of a director
to the corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, provided that such provision may not eliminate or
limit the liability of a director: (i) for any breach of the director's duty of
loyalty to the corporation or its stockholders; (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law; (iii) certain acts concerning unlawful payments of dividends or stock
purchases or redemptions under Section 174 of the GCL; or (iv) for any
transaction from which a director derived an improper personal benefit. The AES
Certificate of Incorporation contains a provision limiting the liability of its
directors as permitted under Delaware law. See " -- Charter and By-Law
Provisions -- Limitations on Director Liability."
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     BERMUDA.  Under Bermuda law, a company is permitted to indemnify any
officer or director, out of the funds of the company, against (i) any liability
incurred by him in defending any proceedings, whether civil or criminal, in
which judgment is given in his favor, or in which he is acquitted, or in
connection with any application under relevant Bermuda legislation in which
relief from liability is granted to him by the court and (ii) any loss or
liability resulting from negligence, default, breach of duty or breach of trust,
save for fraud and dishonesty. The AES Chigen Bye-Laws contain certain
provisions regarding the indemnification of officers and directors. See
" -- Charter and By-Law Provisions -- Indemnification of Directors and
Officers."
 
                                       86
<PAGE>   94
 
     DELAWARE.  Under Delaware law a corporation is permitted to indemnify any
of its officers, directors and certain others against any liability incurred in
any civil, criminal, administrative or investigative proceeding if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal proceeding,
had no reasonable cause to believe his conduct was unlawful. In addition, under
Delaware law, to the extent that a director, officer, employee or agent of a
corporation has been successful on the merits or otherwise in defense of any
proceeding referred to above or in defense of any claim, issue or matter
therein, he must be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith. The AES By-Laws
contain provisions regarding the indemnification of their officers, directors,
agents and employees. See " -- Charter and By-Law Provisions -- Indemnification
of Directors and Officers."
 
INSPECTION OF BOOKS AND RECORDS; SHAREHOLDER AND STOCKHOLDER LISTS
 
     BERMUDA.  Bermuda law provides the general public with a right of
inspection of a Bermuda company's public documents at the office of the
Registrar of Companies in Bermuda, and provides a Bermuda company's shareholders
with a right of inspection of such company's Bye-Laws, minutes of general
(shareholder) meetings and audited financial statements. The register of
shareholders is also open to inspection by shareholders free of charge and, upon
payment of a small fee, by any other person. A Bermuda company is required to
maintain its share register in Bermuda but may establish a branch register
outside of Bermuda. A Bermuda company is required to keep at its registered
office a register of its directors and officers which is open for inspection by
members of the public without charge. Bermuda law does not, however, provide a
general right for shareholders to inspect or obtain copies of any other
corporate records.
 
     DELAWARE.  Any stockholder of record, upon written demand under oath
stating the purpose thereof, has the right during the corporation's usual hours
for business to inspect for any proper purpose the corporation's stock ledger, a
list of its stockholders, and its other books and records, and to make copies or
extracts therefrom.
 
CHARTER AND BY-LAW PROVISIONS
 
     AES's Certificate of Incorporation and By-Laws differ in certain material
respects from the provisions of the AES Chigen Charter and AES Chigen Bye-laws.
The following summary sets forth such differences. The following summary is
qualified by reference to the full text of such documents and does not purport
to deal with all aspects of such documents that may be relevant to AES Chigen
and its shareholders.
 
LIMITATIONS ON DIRECTOR LIABILITY
 
     AES CHIGEN.  The AES Chigen Bye-laws provide that each shareholder agrees
to waive any claim or right of action he may have, whether individually or by or
in the right of AES Chigen against any director of AES Chigen on account of any
action taken by such director, or the failure of such director to take any
action in the performance of his duties with or for AES Chigen; provided,
however, that such waiver shall not apply to any claims or rights of action
arising out of the willful negligence, willful default, fraud or dishonesty of
such director.
 
     AES.  AES's Certificate of Incorporation limits director liability as
described under " -- Comparison of Bermuda and Delaware Corporate
Law -- Limitations on Director Liability."
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     AES CHIGEN.  The AES Chigen Bye-laws generally provide that the officers
and directors of AES Chigen and their heirs shall be indemnified and secured
harmless out of the assets of AES Chigen from and against all actions, costs,
charges, losses, damages and expenses which they or their heirs may incur by
reason of any act done or omitted in the execution of their duty in their
respective offices; provided, that such indemnity shall not extend to any matter
in respect of any willful negligence, willful default, fraud or dishonesty which
may attach to any of such persons.
 
                                       87

     AES.  AES's By-Laws generally provide that AES's officers, directors and
certain others will be indemnified by AES to the fullest extent permitted under
the laws of the State of Delaware against all expenses (including attorneys'
fees, judgments, fines, penalties and amounts paid in settlement) actually and
reasonably incurred by such person in connection with the defense or settlement
of any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, to which such person is a
party by reason of the fact that such person was or is a director or officer of
AES. The indemnification does not apply to any action or suit by or in the right
of AES to procure a judgment in its favor (a "derivative action") in respect of
any claim, issue or matter as to which such person has been adjudged to be
liable to AES unless the Delaware Court of Chancery or other court determines
that such person is entitled to indemnity for expenses.
 
AMENDMENTS TO CHARTER AND BY-LAWS
 
     AES CHIGEN.  Any amendment of the AES Chigen Memorandum of Association and
any rescission, alteration or amendment of the AES Chigen Bye-Laws or adoption
of a new Bye-Law requires: (i) approval by the Board of Directors (including,
until the Time of Conversion, as defined in the Bye-Laws, the affirmative vote
of at least one Class A Director and one Class B Director); (ii) approval by the
shareholders at a general meeting; and (iii) until the Time of Conversion,
separate approval by the holders of a majority of the issued shares of each of
the AES Chigen Class A Common Stock and the AES Chigen Class B Common Stock. Any
amendment of the AES Chigen Memorandum of Association also requires the consent
of the Bermuda Minister of Finance, except for an alteration of share capital.
 
     AES.  AES's Certificate of Incorporation provides that it may be amended in
the manner prescribed by the GCL; therefore, in accordance with Section 242 of
the GCL, it may be amended by a vote of holders of a majority of the outstanding
stock entitled to vote thereon. AES's By-Laws contain a provision whereby such
By-Laws may be amended or repealed by the affirmative vote of a majority of the
stockholders entitled to vote thereon. AES's By-Laws may also be amended or
repealed by a majority of the directors then in office, provided that the
stockholders may determine by majority vote that any action taken by them with
respect to the By-Laws may not be amended or repealed by the Board of Directors.
 
SPECIAL MEETINGS OF STOCKHOLDERS
 
     AES CHIGEN.  The AES Chigen Bye-laws provide that a special meeting of
shareholders may be called by shareholders as provided under the Companies Act.
The Companies Act provides that a special meeting may be called by the holders
of 10% of the paid-up capital of a company which carries the right to attend and
vote at general meetings.
 
     AES.  AES's By-Laws provide that the holders of at least 10% of the
outstanding voting stock of AES may request that the Chairman of the Board or
the President call a special meeting of stockholders.
 
                             SHAREHOLDER PROPOSALS
 
     Any holder of AES Chigen Class A Common Stock who meets the requirements of
the proxy rules under the Exchange Act may submit to AES Chigen's Board of
Directors proposals for inclusion in the proxy materials to be submitted to the
shareholders in connection with an annual general meeting. Shareholders wishing
to have a proposal included in AES Chigen's proxy materials shall comply with
the applicable requirements of the Exchange Act and the rules and regulations
thereunder and shall have the rights provided by Rule 14a-8 under such Act. Any
such proposal should be submitted in writing by notice delivered or mailed,
postage prepaid, to the Secretary, AES China Generating Co. Ltd., 9/F., Allied
Capital Resources Building, 32-38 Ice House Street, Central, Hong Kong. In order
to be eligible under Rule 14a-8 for inclusion in AES Chigen's proxy statement
and accompanying proxy for the 1997 Annual General Meeting shareholder proposals
must have been received by AES Chigen on or before November 1, 1996. If the
Amalgamation is consummated, AES Chigen will have no 1997 Annual General
Meeting.

                       AMENDED AND RESTATED AGREEMENT AND
                              PLAN OF AMALGAMATION
 
     THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF AMALGAMATION, dated as of
November 12, 1996 (this "Agreement"), by and among THE AES CORPORATION, a
Delaware corporation ("AES"), AES CHINA GENERATING CO. LTD., a Bermuda company
("Chigen"), and AES ACQUISITION CO. LTD., a Bermuda company ("Sub"),
 
                             W I T N E S S E T H :
 
     WHEREAS, AES and Chigen entered into an Agreement and Plan of Amalgamation,
dated as of November 12, 1996 (the "Original Amalgamation Agreement"), pursuant
to which AES and Chigen agreed that upon the terms and subject to the conditions
of the Original Amalgamation Agreement and in accordance with the Bermuda
Companies Act 1981, as amended (the "Companies Act"), a Bermuda company to be
formed as a wholly-owned subsidiary of AES would be amalgamated with and into
Chigen (the "Amalgamation"); and
 
     WHEREAS, AES and Chigen now wish to amend the Original Amalgamation
Agreement to (a) include Sub as a party thereto, (b) provide for certain
representations, warranties, covenants and other agreements to be made by Sub in
connection with the Amalgamation and (c) make certain modifications to the
Original Amalgamation Agreement;
 
     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, the parties hereto agree that the terms, covenants
and provisions of the Original Amalgamation Agreement are hereby modified,
amended and restated in their entirety as follows:
 
                                   ARTICLE I
 
                                THE AMALGAMATION
 
     SECTION 1.01.  The Amalgamation.  At the Effective Time (as defined in
Section 1.03 below), and upon the terms and subject to the conditions hereof,
Sub shall be amalgamated with and into Chigen in accordance with the provisions
of the Companies Act. At and after the Effective Time, Chigen shall continue in
the form of the amalgamated company (the "Amalgamated Company") and shall
operate under the name "AES China Generating Co. Ltd.".
 
     SECTION 1.02.  Closing.  The closing of the Amalgamation will take place at
10:00 a.m. on a date to be specified by AES or Sub, which may be on, but shall
be no later than the third business day after, the day on which there shall have
been satisfaction or waiver of the conditions set forth in Article V (the
"Closing Date"), at the offices of Chadbourne & Parke LLP, 30 Rockefeller Plaza,
New York, New York 10112, unless another date or place is agreed to in writing
by the parties hereto.
 
     SECTION 1.03.  Effective Time.  On the date hereof, or as soon as
practicable thereafter, the parties shall file an application for the consent of
the Bermuda Minister of Finance, and on the Closing Date, or as soon as
practicable thereafter, the parties shall file an application for registration
of the Amalgamation with the Bermuda Registrar of Companies and any other
appropriate documents (together, the "Bermuda Applications") executed in
accordance with the relevant provisions of the Companies Act and shall make all
other filings or recordings required under the Companies Act. The Amalgamation
shall become effective at such time as a certificate of amalgamation (the
"Certificate of Amalgamation") is duly issued by the Bermuda Registrar of
Companies (the time the Amalgamation becomes effective being the "Effective
Time").
 
     SECTION 1.04.  Effects of the Amalgamation.  The effect of the Amalgamation
shall be as provided in the applicable provisions of the Companies Act.
 
                                       A-1
<PAGE>   98
 
     SECTION 1.05.  Memorandum of Association and Bye-laws.  (a) The memorandum
of association of Chigen as in effect immediately prior to the Effective Time
shall be the memorandum of association of the Amalgamated Company until
thereafter changed or amended as provided therein or by applicable law.
 
     (b) The Bye-laws of Chigen shall be the bye-laws of the Amalgamated
Company, until thereafter changed or amended as provided therein or by
applicable law. The registration number of the Amalgamated Company in Bermuda
after the Effective Time shall be the same registration number as that of Chigen
immediately prior to the Effective Time.
 
     SECTION 1.06.  Directors.  The persons set forth in Exhibit A attached
hereto shall be the directors of the Amalgamated Company, until the earlier of
their resignation or removal or until their respective successors are duly
elected and qualified, as the case may be.
 
     SECTION 1.07.  Officers.  The officers of Chigen immediately prior to the
Effective Time shall be the officers of the Amalgamated Company, until the
earlier of their resignation or removal or until their respective successors are
duly elected and qualified, as the case may be.
 
                                   ARTICLE II
 
             EFFECT OF THE AMALGAMATION ON THE CAPITAL STOCK OF THE
                CONSTITUENT COMPANIES; EXCHANGE OF CERTIFICATES
 
     SECTION 2.01.  Effect on Capital Stock.  As of the Effective Time, by
virtue of the Amalgamation and without any action on the part of the holders of
any shares of Class A Common Stock, par value $0.01 per share, of Chigen (the
"Class A Common Stock"), or Class B Common Stock, par value $0.01 per share, of
Chigen (the "Class B Common Stock" and together with the Class A Common Stock,
the "Chigen Common Stock") or the holder of any shares of capital stock of Sub:
 
          (a) Capital Stock of Sub.  Each share of the capital stock of Sub
     issued and outstanding immediately prior to the Effective Time shall be
     converted into and become one fully paid and nonassessable share of Common
     Stock of the Amalgamated Company.
 
          (b) Cancellation of Treasury Stock and AES Owned Stock.  Each share of
     Chigen Common Stock that is owned by any subsidiary of Chigen and each
     share of Chigen Common Stock that is owned by AES, Sub or any other
     subsidiary of AES shall automatically be canceled and shall cease to exist,
     and no consideration shall be delivered in exchange therefor.
 
          (c) Cancellation of Class A Common Stock.  Subject to Section 2.01(d),
     each issued and outstanding share of Class A Common Stock (other than
     shares to be canceled in accordance with Section 2.01(b)) shall be canceled
     in consideration of the right to receive AES Common Stock in the ratio of
     (i) 0.2900 of a share of AES Common Stock or (ii) should the average
     closing price of AES Common Stock on the New York Stock Exchange (the
     "NYSE") (with fractions expressed as a decimal rounded to the nearest one
     ten-thousandth) over the 15 consecutive trading day period ending at the
     close of trading on the third trading day immediately prior to the date of
     the Chigen Special Meeting (the "Average Closing Price") be less than
     $45.00, such fraction of a share of AES Common Stock (expressed as a
     decimal rounded to the nearest one ten-thousandth) as is determined by
     dividing $13.05 by the Average Closing Price (the "Exchange Ratio" or the
     "Amalgamation Consideration"). As of the Effective Time, all such shares of
     Class A Common Stock shall no longer be outstanding and shall automatically
     be canceled and retired and shall cease to exist, and each holder of a
     certificate representing any such shares of Class A Common Stock shall
     cease to have any rights with respect thereto, except the right to receive
     the Amalgamation Consideration, without interest.
 
          (d) Shares of Dissenting Shareholders.  Notwithstanding anything in
     this Agreement to the contrary, any issued and outstanding shares of Class
     A Common Stock held by a person who did not vote in favor of the
     Amalgamation and who complies with all the provisions of Bermuda law
     concerning the right of holders of Class A Common Stock to dissent from the
     Amalgamation and require appraisal of their shares of Class A Common Stock
     (such shareholder, a "Dissenting Shareholder", and such shares,
 
                                       A-2
<PAGE>   99
 
     "Dissenting Shares") shall be canceled in consideration for the right to
     receive such consideration as may be payable to such Dissenting Shareholder
     upon completion of the Amalgamation pursuant to the laws of Bermuda. Chigen
     shall give AES (i) prompt notice of any demands for appraisal of shares of
     Class A Common Stock received by Chigen and (ii) the opportunity to
     participate in and direct all negotiations and proceedings with respect to
     any such demands. Chigen shall not, without the prior written consent of
     AES, make any payment with respect to, or settle, offer to settle or
     otherwise negotiate, any such demands.
 
     SECTION 2.02.  Payment for Cancellation of Class A Common Stock in the
Amalgamation.  The manner of making payment for the cancellation of Class A
Common Stock in the Amalgamation shall be as follows:
 
          (a) At the Effective Time, AES shall make available to an exchange
     agent selected by AES and reasonably acceptable to Chigen (the "Exchange
     Agent"), for the benefit of those persons who immediately prior to the
     Effective Time were the holders of Class A Common Stock, a sufficient
     number of certificates representing shares of AES Common Stock required to
     effect the delivery of the aggregate Amalgamation Consideration required to
     be issued pursuant to Section 2.01 (the certificates representing shares of
     AES Common Stock comprising such aggregate Amalgamation Consideration being
     hereinafter referred to as the "Exchange Fund"). The Exchange Agent shall,
     pursuant to irrevocable instructions, deliver the shares of AES Common
     Stock contemplated to be issued pursuant to Section 2.01. The Exchange Fund
     shall not be used for any other purpose.
 
          (b) Promptly after the Effective Time, the Exchange Agent shall mail
     to each registered holder (other than Dissenting Shareholders) of a
     certificate or certificates which immediately prior to the Effective Time
     represented outstanding Class A Common Stock (the "Certificates") (i) a
     form of letter of transmittal (which shall specify that delivery shall be
     effected, and risk of loss and title to the Certificates shall pass, only
     upon proper delivery of the Certificates to the Exchange Agent) and (ii)
     instructions for use in effecting the surrender of the Certificates for
     payment therefor. Upon surrender of Certificates for cancellation to the
     Exchange Agent, together with such letter of transmittal duly executed and
     any other required documents, the holder of such Certificates shall be
     entitled to receive for each of the shares of Class A Common Stock
     represented by such Certificates the Amalgamation Consideration and the
     Certificates so surrendered shall forthwith be canceled. Until so
     surrendered, Certificates shall represent solely the right to receive the
     Amalgamation Consideration and any cash in lieu of fractional shares of AES
     Common Stock as contemplated by Section 2.03 with respect to each of the
     shares of Class A Common Stock represented thereby. No dividends or other
     distributions that are declared after the Effective Time on shares of AES
     Common Stock and payable to the holders of record thereof after the
     Effective Time will be paid to persons entitled by reason of the
     Amalgamation to receive shares of AES Common Stock until such persons
     surrender their Certificates. Upon such surrender, there shall be paid to
     the person in whose name shares of AES Common Stock are issued any
     dividends or other distributions having a record date after the Effective
     Time and payable with respect to such shares of AES Common Stock between
     the Effective Time and the time of such surrender. After such surrender
     there shall be paid to the person in whose name shares of AES Common Stock
     are issued any dividends or other distributions on such shares of AES
     Common Stock which shall have a record date after the Effective Time and
     prior to such surrender and a payment date after such surrender and such
     payment shall be made on such payment date. In no event shall the persons
     entitled to receive such dividends or other distributions be entitled to
     receive interest on such dividends or other distributions. If any cash or
     any certificate representing shares of AES Common Stock is to be paid to or
     issued in a name other than that in which the Certificate surrendered in
     exchange therefor is registered, it shall be a condition of such exchange
     that the Certificate so surrendered shall be properly endorsed and
     otherwise in proper form for transfer and that the person requesting such
     exchange shall pay to the Exchange Agent any transfer or other taxes
     required by reason of the issuance of certificates for such shares of AES
     Common Stock in a name other than that of the registered holder of the
     Certificate surrendered, or shall establish to the satisfaction of the
     Exchange Agent that such tax has been paid or is not applicable.
     Notwithstanding the foregoing, neither the Exchange Agent nor any party
     hereto shall be liable to a
 
                                       A-3
<PAGE>   100
 
     holder of Class A Common Stock for any shares of AES Common Stock or
     dividends thereon or, in accordance with Section 2.03, proceeds of the sale
     of fractional interests, delivered to a public official pursuant to
     applicable escheat law. The Exchange Agent shall not be entitled to vote or
     exercise any rights of ownership with respect to shares of AES Common Stock
     held by it from time to time hereunder, except that it shall receive and
     hold all dividends or other distributions paid or distributed with respect
     to such shares of AES Common Stock for the account of the persons entitled
     thereto.
 
          (c) Subject to the requirements of applicable law, certificates
     surrendered for exchange by any person constituting an "affiliate" of
     Chigen for purposes of Rule 145 of the Securities Act of 1933, as amended
     (together with the rules and regulations promulgated thereunder, the
     "Securities Act") shall not be exchanged for certificates representing
     shares of AES Common Stock until AES has received from such person a
     written "affiliate" agreement in a form reasonably acceptable to AES and
     Chigen. Chigen shall use reasonable efforts to cause each such person to
     deliver such written agreement to AES on or prior to the Closing Date.
 
          (d) Any portion of the Exchange Fund which remains unclaimed by the
     former shareholders of Chigen for one year after the Effective Time shall
     be delivered to AES, upon demand of AES, and any former shareholders of
     Chigen shall thereafter look only to AES for payment of their claim for the
     Amalgamation Consideration for the shares or for any cash in lieu of
     fractional shares of AES Common Stock.
 
          (e) If any Certificate shall have been lost, stolen or destroyed, upon
     the making of an affidavit of that fact by the person claiming such
     Certificate to be lost, stolen or destroyed and, if required by the
     Amalgamated Company, the execution of an indemnity agreement by such person
     and/or the posting by such person of a bond in such reasonable amount as
     the Amalgamated Company may reasonably direct, as indemnity against any
     claim that may be made against it with respect to such Certificate, the
     Exchange Agent will issue in exchange for such lost, stolen or destroyed
     Certificate the shares of AES Common Stock, cash in lieu of fractional
     shares of AES Common Stock and unpaid dividends and distributions on shares
     of AES Common Stock deliverable in respect thereof pursuant to this
     Agreement.
 
     SECTION 2.03.  No Fractional Shares.  No fractional shares of AES Common
Stock shall be issued in the Amalgamation and no fractional share interests will
entitle the owner thereof to vote or to any rights of a stockholder of AES. In
lieu of any such fractional securities, each holder of shares of Class A Common
Stock who would otherwise have been entitled to a fraction of a share of AES
Common Stock upon surrender of Certificates for cancellation pursuant to this
Article II, after aggregating all shares of AES Common Stock which such holder
would be entitled to receive under Section 2.01(c), will be paid an amount in
cash (without interest) equal to the closing price per share of AES Common Stock
on the trading day prior to the day on which the Effective Time occurs
multiplied by the fraction of a share of AES Common Stock to which such holder
would otherwise be entitled. As soon as practicable after the determination of
the amount of cash to be paid to former shareholders of Chigen in lieu of any
fractional interests, the Exchange Agent shall make available in accordance with
this Agreement such amounts to such former shareholders.
 
     SECTION 2.04.  Transfer of Shares after the Effective Time.  No transfers
of shares of Class A Common Stock shall be made on the share transfer books of
Chigen after the close of business on the day prior to the date of the Effective
Time.
 
     SECTION 2.05.  Stock Options.  Pursuant to the AES China Generating Co.
Ltd. Incentive Stock Option Plan (the "Option Plan"), all outstanding options
issued thereunder (the "Options") shall, as of the Effective Time, automatically
and without any action on the part of the holders thereof, become options for
AES Common Stock. The Option Plan shall remain in full force and effect after
the Effective Time unless otherwise amended or terminated in accordance with the
plan document. The date of grant for each option shall be the date on which the
corresponding Option was originally granted. At the Effective Time, AES shall
reserve for issuance the number of shares of AES Common Stock that will become
issuable upon the exercise of the options pursuant to this Section 2.05. Nothing
in this Section 2.05 shall affect the schedule of vesting (or the acceleration
thereof) with respect to the Options. As soon as practicable after the Effective
Time, AES shall file a registration statement or registration statements on Form
S-8 (or any successor form), or
 
                                       A-4
<PAGE>   101
 
another appropriate form with respect to the shares of AES Common Stock subject
to the options, and shall use its best efforts to maintain the effectiveness of
such registration statement or registration statements (and maintain the current
status of the prospectus contained therein) for so long as any options remain
outstanding. It is the intention of the parties that, subject to applicable law,
the options qualify following the Effective Time as "incentive stock options"
(as defined in Section 422 of the United States Internal Revenue Code of 1986,
as amended (the "Code")) to the extent that the Options qualified as incentive
stock options prior to the Effective Time and, accordingly, the provisions of
this Section 2.05 shall be deemed amended to the extent necessary to maintain
such status of the options.
 
     SECTION 2.06.  Adjustments to Exchange Ratio, etc.  The exchange ratios set
forth in Sections 2.01 and 5.02(f) and any floor amounts shall be adjusted to
reflect fully the effect of any stock split (including a consolidation) of AES
Common Stock or a dividend payable in AES Common Stock, or any other
distribution of securities or dividend (in cash or otherwise) to holders of AES

                         REPRESENTATIONS AND WARRANTIES
 
     SECTION 3.01.  Representations and Warranties of Chigen.  Chigen represents
and warrants to AES as follows:
 
          (a) Organization, Standing and Corporate Power.  Chigen is a company
     duly organized, validly existing and in compliance under the laws of
     Bermuda and has the requisite corporate power and authority to carry on its
     business as now being conducted. Chigen is duly qualified or licensed to do
     business and is in good standing in each jurisdiction in which the nature
     of its business or the ownership or leasing of its properties makes such
     qualification or licensing necessary, other than in such jurisdictions
     where the failure to be so qualified, licensed or in good standing
     (individually or in the aggregate) would not have a Material Adverse Effect
     (as defined in Section 7.03(c) below) in respect of Chigen.
 
          (b) Subsidiaries.  All the outstanding shares of capital stock,
     partnership interests or other equity interests owned by Chigen in each
     subsidiary in which Chigen has a direct or indirect interest are, directly
     or indirectly, free and clear of all Liens (as defined in Section 7.03(b)
     below).
 
          (c) Capital Structure.  The authorized capital stock of Chigen is
     substantially as described in the Chigen SEC Documents (as defined in
     Section 3.01(e) below). All outstanding shares of capital stock of Chigen
     are, and all shares which may be issued will be, when issued, duly
     authorized, validly issued and fully paid and not subject to preemptive
     rights. There are no bonds, debentures, notes or other indebtedness of
     Chigen having the right to vote (or convertible into, or exchangeable for,
     securities having the right to vote) on any matters on which shareholders
     of Chigen may vote. Except as set forth above, as of the date of this
     Agreement, there are no outstanding securities, options, warrants, calls,
     rights, commitments, agreements, arrangements or undertakings of any kind
     to which Chigen is a party or by which it is bound obligating Chigen to
     issue, deliver or sell, or cause to be issued, delivered or sold,
     additional shares of capital stock or other voting securities of Chigen or
     obligating Chigen to issue, grant, extend or enter into any such security,
     option, warrant, call, right, commitment, agreement, arrangement or
     undertaking. There are not any outstanding contractual obligations of
     Chigen to repurchase, redeem or otherwise acquire any shares of capital
     stock of Chigen.
 
          (d) Authority; Noncontravention.  Chigen has the requisite corporate
     power and authority to enter into this Agreement and, subject to the
     approval of the Amalgamation and this Agreement by the requisite vote of
     the holders of the outstanding shares of Chigen, to consummate the
     transactions contemplated hereby. The execution and delivery of this
     Agreement by Chigen and the consummation by Chigen of the transactions
     contemplated by this Agreement have been duly authorized by all necessary
     corporate action on the part of Chigen, subject, in the case of this
     Agreement, to approval of the
 
                                       A-5
<PAGE>   102
 
     Amalgamation and this Agreement by the requisite vote of the holders of the
     outstanding shares of Chigen Common Stock. This Agreement has been duly
     executed and delivered by Chigen and, assuming this Agreement constitutes
     the valid and binding obligation of AES and Sub, this Agreement constitutes
     the valid and binding obligation of Chigen, enforceable against Chigen in
     accordance with its terms. The execution and delivery of this Agreement
     does not, and the consummation of the transactions contemplated by this
     Agreement and compliance with the provisions of this Agreement will not,
     conflict with, or result in any violation of or default (with or without
     notice or lapse of time, or both) under, or give rise to a right of
     termination, cancellation or acceleration of any obligation or to loss of a
     material benefit under, or result in the creation of any Lien upon any of
     the properties or assets of Chigen or any of its subsidiaries under, (i)
     the Memorandum of Association or Bye-laws of Chigen or the comparable
     charter or organizational documents of any of its subsidiaries, (ii) any
     loan or credit agreement, note, bond, mortgage, indenture, lease or other
     agreement, instrument, permit, concession, franchise or license applicable
     to Chigen or any of its subsidiaries or their respective properties or
     assets or (iii) subject to the governmental filings and other matters
     referred to in the following sentence, any judgment, order, decree,
     statute, law, ordinance, rule or regulation applicable to Chigen or any of
     its subsidiaries or their respective properties or assets, other than, in
     the case of clauses (ii) or (iii), any such conflicts, violations,
     defaults, rights or Liens that individually or in the aggregate would not
     (x) have a Material Adverse Effect in respect of Chigen, (y) impair in any
     material respect the ability of Chigen to perform its obligations under
     this Agreement or (z) prevent the consummation of any of the transactions
     contemplated by this Agreement. No consent, approval, order or
     authorization of, or registration, declaration or filing with, any U.S.
     federal, state or local government or foreign government or any court,
     administrative or regulatory agency or commission or other governmental
     authority or agency, domestic or foreign (a "Governmental Entity"), is
     required by Chigen or any of its subsidiaries in connection with the
     execution and delivery of this Agreement by Chigen or the consummation by
     Chigen of the transactions contemplated by this Agreement, except for (i)
     the filing with the United States Securities and Exchange Commission (the
     "SEC") and the SEC's review of (x) the proxy statement relating to the
     approval by Chigen's shareholders of the Amalgamation and this Agreement
     (as amended or supplemented from time to time, the "Proxy Statement") and
     (y) such other filings under the Securities Exchange Act of 1934, as
     amended (together with the rules and regulations promulgated thereunder,
     the "Exchange Act"), as may be required in connection with this Agreement
     and the transactions contemplated by this Agreement, (ii) any filings made
     in compliance with the rules and regulations of the NYSE and the Nasdaq
     National Market System, (iii) the filing of the Bermuda Applications, and
     the appropriate documents with the relevant authorities of other
     jurisdictions in which Chigen is qualified to do business, (iv) such
     filings as may be required by any applicable state securities or "blue sky"
     laws or state takeover laws, (v) such filings, consents, approvals, orders,
     registrations and declarations as may be required under the laws of any
     foreign country in which Chigen or any of its subsidiaries conducts any
     business or owns any assets, (vi) the consent of the Bermuda Minister of
     Finance to amalgamate Chigen with Sub, (vii) the issuance by the Bermuda
     Registrar of Companies of the Certificate of Amalgamation, and (viii) such
     other consents, approvals, orders, authorizations, registrations,
     declarations and filings the failure of which to be obtained or made would
     not, individually or in the aggregate (a) have a Material Adverse Effect in
     respect of Chigen, (b) impair in any material respect the ability of Chigen
     to perform its obligations under this Agreement or (c) prevent or
     significantly delay the consummation of the transactions contemplated by
     this Agreement.
 
          (e) SEC Documents; Financial Statements.  Chigen has filed all
     required reports, forms and other documents with the SEC since February 23,
     1994 (the "Chigen SEC Documents"). As of their respective dates, (i) the
     Chigen SEC Documents complied in all material respects with the
     requirements of the Securities Act or the Exchange Act, as the case may be,
     applicable to such Chigen SEC Documents, and (ii) none of the Chigen SEC
     Documents contained any untrue statement of a material fact or omitted to
     state a material fact required to be stated therein or necessary in order
     to make the statements therein, in light of the circumstances under which
     they were made, not misleading. Except to the extent that information
     contained in any Chigen SEC Document has been revised or superseded by a
     later-filed Chigen SEC Document filed and publicly available prior to the
     date of this Agreement, none of
 
                                       A-6

     or omits to state any material fact required to be stated therein or
     necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading. The financial
     statements of Chigen included in the Chigen SEC Documents comply as to form
     in all material respects with applicable accounting requirements and the
     published rules and regulations of the SEC with respect thereto, have been
     prepared in accordance with United States generally accepted accounting
     principles ("GAAP") (except, in the case of unaudited statements, as
     permitted by Form 10-Q) applied on a consistent basis during the periods
     involved (except as may be indicated in the notes thereto) and fairly
     present the consolidated financial position of Chigen and its consolidated
     subsidiaries as of the dates thereof and the consolidated results of their
     operations and cash flows for the periods then ended (subject, in the case
     of unaudited statements, to normal year-end audit adjustments). Except as
     set forth in the Chigen SEC Documents filed and publicly available prior to
     the date of this Agreement, and except for Chigen's planned offering of
     notes due 2006 (the "Chigen Debt Offering") and except for liabilities and
     obligations incurred in the ordinary course of business consistent with
     past practice since the date of the most recent consolidated balance sheet
     included in the Chigen SEC Documents filed and publicly available prior to
     the date of this Agreement and except for liabilities and obligations which
     would not, individually or in the aggregate, have a Material Adverse Effect
     in respect of Chigen, neither Chigen nor any of its subsidiaries has any
     liabilities or obligations of any nature (whether accrued, absolute,
     contingent or otherwise) required by GAAP to be set forth on a consolidated
     balance sheet of Chigen and its consolidated subsidiaries or in the notes
     thereto.
 
          (f) Absence of Certain Changes or Events.  Except as disclosed in the
     Chigen SEC Documents filed and publicly available prior to the date of this
     Agreement, and, except for the Chigen Debt Offering, since November 30,
     1995, Chigen has conducted its business only in the ordinary course, and
     there has not been (i) any Material Adverse Change (as defined in
     sec. 7.03(c) below) in respect of Chigen, (ii) any split, combination or
     reclassification of any of its capital stock or any issuance or the
     authorization of any issuance of any other securities in respect of, in
     lieu of or in substitution for shares of its capital stock, (iii) (x) any
     granting by Chigen to any officer of Chigen of any increase in
     compensation, except in the ordinary course of business consistent with
     prior practice, as was required under employment agreements in effect as of
     the date of the most recent audited financial statements included in the
     Chigen SEC Documents filed and publicly available prior to the date of this
     Agreement, (y) any granting by Chigen to any such officer of any increase
     in severance or termination pay, except as was required under employment,
     severance or termination agreements in effect as of the date of the most
     recent audited financial statements included in the Chigen SEC Documents
     filed and publicly available prior to the date of this Agreement or (z) any
     entry by Chigen or any of its subsidiaries into any employment, severance
     or termination agreement with any such officer, (iv) any damage,
     destruction or loss, whether or not covered by insurance, that has or
     reasonably could be expected to have a Material Adverse Effect in respect
     of Chigen or (v) any change in accounting methods, principles or practices
     by Chigen materially affecting its assets, liabilities or business, except
     insofar as may have been required by a change in GAAP.
 
          (g) Litigation.  Except as disclosed in the Chigen SEC Documents filed
     and publicly available prior to the date of this Agreement, there is no
     suit, action or proceeding pending or, to the knowledge of Chigen,
     threatened against Chigen or any of its subsidiaries that, individually or
     in the aggregate, could reasonably be expected to have a Material Adverse
     Effect in respect of Chigen; it being understood that this representation
     shall not include any litigation of the nature described in Section
     5.02(a)(i) through (iv).
 
          (h) Compliance with Applicable Laws.  Each of Chigen and its
     subsidiaries has in effect all foreign governmental approvals,
     authorizations, certificates, filings, franchises, licenses, notices,
     permits and rights, including all authorizations under environmental laws
     ("Permits"), necessary for it to own, lease or operate its properties and
     assets and to carry on its business as now conducted, and there has
     occurred no default under any such Permit, except for the lack of Permits
     and except for defaults under Permits which such lack or default
     individually or in the aggregate would not have a Material Adverse Effect
     in respect of Chigen. Except as disclosed in the Chigen SEC Documents filed
     and publicly available prior to
 
                                       A-7

     the date of this Agreement, Chigen and its subsidiaries are in compliance
     with all applicable statutes, laws, ordinances, rules, orders and
     regulations of any Governmental Entity, except for any noncompliance which
     individually or in the aggregate would not have a Material Adverse Effect
     in respect of Chigen.
 
          (i) Brokers; Schedule of Fees and Expenses.  No broker, investment
     banker or financial advisor or other person, other than Merrill Lynch,

     finder's, financial advisor's or other similar fee or commission in
     connection with the transactions contemplated by this Agreement based upon
     arrangements made by or on behalf of Chigen. Chigen has provided AES true
     and correct copies of all agreements between Chigen and Merrill Lynch.
 
          (j) Opinion of Financial Advisor.  Chigen has received the opinion of
     Merrill Lynch, to the effect that, as of the date of this Agreement, the
     consideration to be received in the Amalgamation by the holders of Class A
     Common Stock is fair to the holders of Class A Common Stock from a
     financial point of view, and a complete and correct copy of such opinion
     has been, or promptly upon receipt thereof will be, delivered to AES.
 
          (k) Board Recommendation.  At a meeting duly called and held in
     compliance with Chigen's Bye-laws, (i) a Special Committee of the Board of
     Directors of Chigen comprised of the directors elected by the holders of
     the Class A Common Stock (the "Special Committee") has adopted a resolution
     approving the Amalgamation and recommended that the Board of Directors of
     Chigen approve this Agreement and the transactions contemplated hereby,
     (ii) the Board of Directors of Chigen has adopted a resolution (a)
     approving the Amalgamation, based on a determination that the Amalgamation

     Delaware, Sub is an exempted company duly organized, validly existing and
     in compliance under the laws of Bermuda and each of them has the requisite
     corporate power and authority to carry on its business as now being

     and is in good standing in each jurisdiction in which the nature of its
     business or the ownership or leasing of its properties makes such
     qualification or licensing necessary, other than in such jurisdictions
     where the failure to be so qualified or licensed (individually or in the
     aggregate) would not have a Material Adverse Effect in respect of AES. AES
     has delivered to Chigen complete and correct copies of its certificate of
     incorporation and by-laws, and the memorandum of association and bye-laws
     of Sub, in each case as amended to the date of this Agreement.

     substantially as described in the AES SEC Documents (as defined in Section
     3.02(d) below). AES does not own any shares of the Class A Common Stock of
     Chigen.
 
          (c) Authority; Noncontravention.  AES and Sub have all requisite

     contemplated by this Agreement have been duly authorized by all necessary
     corporate action on the part of AES and Sub. This Agreement has been duly
     executed and delivered by AES and Sub and, assuming this Agreement
     constitutes the valid and binding obligation of Chigen, this Agreement
     constitutes a valid and binding obligation of AES and Sub, enforceable
     against AES and Sub, as applicable, in accordance with its terms. The
     execution and delivery of this Agreement does not, and the consummation of
     the transactions contemplated by this Agreement and compliance with the
     provisions of this Agreement will not, conflict with, or result in any
     violation of or default (with or without notice or lapse of time, or both)
     under, or give rise to a right of termination, cancellation or acceleration
     of any obligation or to loss of a material
 
                                       A-8

     properties or assets of AES under, (i) the certificate of incorporation or
     by-laws of AES or the memorandum of association or bye-laws of Sub, (ii)
     any loan or credit agreement, note, bond, mortgage, indenture, lease or
     other agreement, instrument, permit, concession, franchise or license

     matters referred to in the following sentence, any judgment, order, decree,
     statute, law, ordinance, rule or regulation applicable to AES or Sub or
     their respective properties or assets, other than, in the case of clauses
     (ii) or (iii), any such conflicts, violations, defaults, rights or Liens
     that (a) will have been waived prior to the Effective Time or (b) would not
     individually or in the aggregate (x) have a Material Adverse Effect in
     respect of AES, (y) impair in any material respect the ability of AES and
     Sub to perform their respective obligations under this Agreement or (z)
     prevent the consummation of any of the transactions contemplated by this
     Agreement. No consent, approval, order or authorization of, or
     registration, declaration or filing with, any Governmental Entity is
     required by AES or Sub in connection with the execution and delivery of
     this Agreement or the consummation by AES or Sub, as the case may be, of
     any of the transactions contemplated by this Agreement, except for (i) the
     filing with the SEC of (x) the Registration Statement (as defined in
     Section 4.01 below), and (y) such other filings under the Exchange Act as

     registrations, declarations and filings the failure of which to be obtained
     or made would not, individually or in the aggregate (a) have a Material
     Adverse Effect in respect of AES, (b) impair the ability of AES or Sub to
     perform their respective obligations under this Agreement or (c) prevent or
     significantly delay the consummation of any transaction contemplated by
     this Agreement.
 
          (d) SEC Documents; Financial Statements.  AES has filed all required
     reports, forms and other documents with the SEC since January 1, 1994 (the
     "AES SEC Documents"). As of their respective dates, (i) the AES SEC

     Securities Act or the Exchange Act, as the case may be, applicable to such

     untrue statement of a material fact or omitted to state a material fact
     required to be stated therein or necessary in order to make the statements

     misleading. Except to the extent that information contained in any AES SEC
     Document has been revised or superseded by a later-filed AES SEC Document
     filed and publicly available prior to the date of this Agreement, none of

     included in the AES SEC Documents comply as to form in all material
     respects with applicable accounting requirements and the published rules
     and regulations of the SEC with respect thereto, have been prepared in

     present the consolidated financial position of AES and its consolidated
     subsidiaries as of the dates thereof and the consolidated results of their
     operations and cash flows for the periods then ended (subject, in the case
     of unaudited statements, to normal year-end audit adjustments). Except as
     set forth in the AES SEC Documents filed and publicly available prior to
     the date of this Agreement, and except for liabilities and obligations
     incurred in the ordinary course of business consistent with past practice
     since the date of the most recent consolidated balance sheet included in

     assets, liabilities or business, except insofar as may have been required
     by a change in GAAP.

     and publicly available prior to the date of this Agreement, there is no
     suit, action or proceeding pending or, to the knowledge of AES, threatened
     against AES or any of its subsidiaries that, individually or in the
     aggregate, could reasonably be expected to have a Material Adverse Effect
     in respect of AES.
 
          (g) Brokers.  No broker, investment banker, financial advisor or other
     person, the fees and expenses of which will be paid by AES, is entitled to
     any broker's, finder's, financial advisor's or other similar fee or

promptly as practicable after the execution of this Agreement, AES and Chigen
shall prepare and file with the SEC a preliminary proxy statement for use in
connection with the Chigen Class A Meeting (as defined in Section 4.02 below)
and the Chigen Special Meeting (as defined in Section 4.02 below) (the "Proxy
Statement") and, once the SEC has reviewed the Proxy Statement, a registration
statement on Form S-4 (together with all amendments thereto, the "Registration
Statement") in connection with the registration under the Securities Act of the
shares of AES Common Stock to be issued to the holders of the Class A Common
Stock pursuant to the Amalgamation. AES, Sub and Chigen shall cooperate with
each other in connection with any other filings with the SEC that any of them is
obligated to make as a result of the transactions contemplated hereby. AES and
Chigen each shall use all reasonable efforts to cause the Registration Statement

the SEC staff as promptly as practicable. Prior to the effective date of the
Registration Statement, AES shall take all or any action required under any
applicable federal or state securities laws in connection with the issuance of
shares of AES Common Stock pursuant to the Amalgamation. Each of Chigen and AES
shall pay its own expenses incurred in connection with the Registration
Statement, the Proxy Statement, the Chigen Class A Meeting and the Chigen
Special Meeting, including, without limitation, the fees and disbursements of
their respective counsel, accountants and other representatives, except that
Chigen and AES each shall pay one-half of any printing expenses incurred in
connection therewith and Chigen shall pay any filing fees with respect to the
filing of the Proxy Statement with the SEC. Such fee shall be reimbursed to
Chigen in the event this Agreement is terminated. Chigen shall furnish all
information concerning Chigen as AES may reasonably request in connection with
such actions and the preparation of the Registration Statement. As promptly as
practicable after the Proxy Statement has been reviewed by the SEC and the
Registration Statement shall have become effective, Chigen shall mail the Proxy

Statement to its shareholders. The Proxy Statement shall include the
recommendation of the Special Committee and the recommendation of the Board of
Directors of Chigen in favor of the Amalgamation, unless the Special Committee
has, in accordance with the terms of this Agreement, withdrawn or modified its
recommendation or approval of this Agreement.
 
     (ii) No amendment or supplement to the Registration Statement or the Proxy
Statement will be made by AES or Chigen without the other's approval, which
shall not be unreasonably withheld. AES and Chigen each will advise the other,
promptly after it receives notice thereof, of the time when the Registration
Statement has become effective or any supplement or amendment has been filed,
the issuance of any stop order, the suspension of the qualification of the AES
Common Stock issuable in connection with the Amalgamation for offering or sale
in any jurisdiction, or any request by the SEC for amendment of the Registration
Statement or the Proxy Statement or comments thereon and responses thereto or
requests by the SEC for additional information.
 
     (iii) AES shall promptly prepare and submit to the NYSE a listing
application covering the shares of AES Common Stock issuable in the
Amalgamation, and shall use its reasonable best efforts to obtain, prior to the
Effective Time, approval for the listing of such AES Common Stock, subject to
official notice of issuance, and Chigen shall cooperate fully with AES with
respect to such listing.
 
     (b) AES represents, warrants and agrees that none of the information
supplied or to be supplied by AES for inclusion or incorporation by reference in

time the Registration Statement is filed with the SEC or declared effective,
(ii) the time the Proxy Statement (or any amendment thereof or supplement
thereto) is first mailed to the shareholders of Chigen, (iii) the time of the
Chigen Class A Meeting and the Chigen Special Meeting and (iv) the Effective
Time, contain any untrue statement of a material fact or any statement which, at
such time and in light of the circumstances under which it is made, is false or
misleading with respect to any material fact, or omit to state any material fact
required to be stated therein, or necessary in order to make the statements
therein not false or misleading. If at any time prior to the Effective Time any
event or circumstance relating to AES or any subsidiary of AES, or their
respective officers or directors, should be discovered by AES which should be
set forth in an amendment or a supplement to the Registration Statement or the
Proxy Statement, AES shall promptly inform Chigen of such event or circumstance.
Notwithstanding the foregoing, AES makes no representation or warranty with
respect to any information which is supplied for inclusion or incorporation by
reference in the Registration Statement (including the Proxy Statement) by
Chigen or any of its representatives and which is contained therein. All
documents that AES is responsible for filing with the SEC in connection with the
transactions contemplated hereby will comply as to form and substance in all
material respects with the applicable requirements of the Securities Act and the
Exchange Act.
 
     (c) Chigen represents, warrants and agrees that none of the information
supplied or to be supplied by Chigen for inclusion or incorporation by reference
in the Registration Statement (including the Proxy Statement) shall, at the
respective times the Registration Statement is filed with the SEC or declared
effective or the Proxy Statement contained in the Registration Statement is
first published, sent or given to the holders of Class A Common Stock, and at
the Effective Time, contain any untrue statement of a material fact or any
statement which, at such time and in light of the circumstances under which it
is made, is false or misleading with respect to any material fact, or omit to

Chigen, or their respective officers or directors, should be discovered by
Chigen which should be set forth in an amendment or supplement to the
Registration Statement or the Proxy Statement, Chigen shall promptly inform AES
of such event of circumstance. Notwithstanding the foregoing, Chigen makes no
representation or warranty with respect to any information which is supplied for
inclusion or incorporation by reference in the Registration Statement (including
the Proxy Statement) by AES or Sub or any of their representatives and which is
contained therein. All documents that Chigen is responsible for filing with the
SEC in connection with the transactions contemplated hereby will comply as to

     (d) Chigen, AES and Sub each hereby (i) consents to the use of its name
and, on behalf of its subsidiaries and affiliates, the names of such
subsidiaries and affiliates, and to the inclusion of financial statements and
business information relating to such party and its subsidiaries and affiliates
(in each case, to the extent required by applicable securities laws), in the
Registration Statement and the Proxy Statement, (ii) agrees to use all
reasonable efforts to obtain the written consent of any person or entity
retained by it which may be required to be named (as an expert or otherwise) in
the Registration Statement or the Proxy Statement, and (iii) agrees to cooperate
fully, and agrees to use all reasonable efforts to cause its subsidiaries and
affiliates to cooperate fully, with any legal counsel, investment banker,
accountant or other agent or representative retained by any of the parties
specified in clause (i) above in connection with the preparation of any and all
information required, as determined after consultation with each party's
counsel, to be disclosed by applicable securities laws in the Registration
Statement or the Proxy Statement.
 
     SECTION 4.02.  Shareholders' Meetings.  Chigen shall call a special class
meeting of the holders of Class A Common Stock (the "Chigen Class A Meeting")
and a special general meeting of its shareholders (the "Chigen Special Meeting")
as promptly as practicable for the purpose of voting upon the approval of this
Agreement and the Amalgamation and Chigen shall use all commercially reasonable
efforts to hold the Chigen Class A Meeting and the Chigen Special Meeting as
soon as practicable after the date on which the Registration Statement becomes
effective. Unless the Special Committee has, in accordance with the terms of
this Agreement, withdrawn or modified its recommendation or approval of this
Agreement, Chigen shall use all commercially reasonable efforts to solicit from
its shareholders proxies in favor of the approval of this Agreement and the
Amalgamation, and shall take all other action reasonably necessary or advisable
to secure the vote or consent of shareholders required by the Companies Act to
obtain such approvals. AES shall vote its shares of Class B Common Stock in
favor of this Agreement and the transactions contemplated hereby.
 
     SECTION 4.03.  No Solicitation.  (a) Chigen shall not, nor shall it permit
any of its subsidiaries to, nor shall it authorize or permit any officer,
director or employee of, or any investment banker, attorney or other advisor or
representative of, Chigen or any of its subsidiaries to, (i) solicit or
initiate, or encourage the submission of, any Takeover Proposal (as hereinafter
defined) or (ii) participate in any discussions or negotiations regarding, or
furnish to any person any information with respect to, or take any other action
to facilitate any inquiries or the making of any proposal that constitutes, or
may reasonably be expected to lead to, any Takeover Proposal; provided, however,
that, if in the opinion of the Special Committee, after consultation with
counsel, such failure to act would be inconsistent with its fiduciary duties to
Chigen or the holders of Class A Common Stock under applicable law, Chigen may,
in response to an unsolicited Takeover Proposal, and subject to compliance with
Section 4.03(c), (a) furnish information with respect to Chigen to any person
pursuant to a confidentiality agreement and (b) participate in negotiations
regarding such Takeover Proposal. Without limiting the foregoing, it is
understood that any violation of the restrictions set forth in the preceding
sentence by any executive officer of Chigen or any of its subsidiaries or any
investment banker, attorney or other advisor or representative of Chigen or any
of its subsidiaries, whether or not such person is purporting to act on behalf
of Chigen or any of its subsidiaries or otherwise, shall be deemed to be a
breach of this Section 4.03(a) by Chigen. For purposes of this Agreement,
"Takeover Proposal" means any inquiry, proposal or offer from any person
relating to any direct or indirect acquisition or purchase of a substantial
amount of assets of Chigen or any of its subsidiaries (other than investors in
the ordinary course of business) or of over 20% of any class of equity
securities of Chigen or any of its subsidiaries or any tender offer or exchange
offer that if consummated would result in any person beneficially owning 20% or
more of any class of equity securities of Chigen or any of its subsidiaries, or
any amalgamation, consolidation, business combination, sale of substantially all
assets, recapitalization, liquidation, dissolution or similar transaction
involving Chigen or any of its subsidiaries other than the transactions
contemplated by this Agreement, or any other transaction the consummation of
which would reasonably be expected to impede, interfere with, prevent or
materially delay the Amalgamation or which would reasonably be expected to
dilute materially the benefits to AES of the transactions contemplated hereby.
 
     (b) Except as set forth herein or as required by Bermuda law, the Special
Committee shall not (i) withdraw or modify, or propose to withdraw or modify, in
a manner adverse to AES or Sub, the approval or recommendation by such Special
Committee of the Amalgamation or this Agreement, (ii) approve or
 
                                      A-12
<PAGE>   109
 
recommend, or propose to approve or recommend, any Takeover Proposal or (iii)
enter into any agreement with respect to any Takeover Proposal. Notwithstanding
the foregoing, if in the opinion of the Special Committee, after consultation
with counsel, failure to do any of the foregoing would be inconsistent with its
fiduciary duties to Chigen or the holders of the Class A Common Stock under
applicable law, the Special Committee may (subject to the terms of this and the
following sentences) withdraw or modify its approval or recommendation of the
Amalgamation or this Agreement, approve or recommend a Superior Proposal (as
hereinafter defined), or enter into an agreement with respect to a Superior
Proposal, in each case relating to the receipt of a Superior Proposal at any
time after the second business day following AES's receipt of written notice (a
"Notice of Superior Proposal") advising AES that the Special Committee has
received a Superior Proposal, specifying the material terms and conditions of
such Superior Proposal and identifying the person making such Superior Proposal;
provided that Chigen shall not enter into an agreement with respect to a
Superior Proposal unless Chigen shall have furnished AES with written notice no
later than 12:00 noon, New York City time, one day in advance of any date that
it intends to enter into such agreement (it being understood that such time
periods may be concurrent). In addition, if Chigen proposes to enter into an
agreement with respect to any Takeover Proposal, it shall concurrently with
entering into such agreement pay, or cause to be paid, to AES the Expenses (as
defined in Section 4.07(b) below). For purposes of this Agreement, a "Superior
Proposal" means any bona fide Takeover Proposal to acquire, directly or
indirectly, for consideration consisting of cash and/or securities, more than
50% of the shares of Class A Common Stock then outstanding or all or
substantially all the assets of Chigen and otherwise on terms which the Special
Committee determines in its good faith judgment (based on the advice of a
financial advisor of nationally recognized reputation) to be more favorable to
Chigen or the holders of the Class A Common Stock than the Amalgamation.
 
     (c) In addition to the obligations of Chigen set forth in Section 4.03(b),
Chigen shall immediately advise AES orally and in writing of any request for
information or of any Takeover Proposal, or any inquiry with respect to or which
could lead to any Takeover Proposal, the material terms and conditions of such
request, Takeover Proposal or inquiry, and the identity of the person making any
such Takeover Proposal or inquiry. Chigen will keep AES fully informed of the
status and details (including amendments or proposed amendments) of any such
request, Takeover Proposal or inquiry.
 
     (d) Nothing contained in this Section 4.03 shall prohibit Chigen from
taking and disclosing to its shareholders a position contemplated by Rule
14e-2(a) under the Exchange Act or from making any disclosure to the holders of
Class A Common Stock if, in the opinion of the Special Committee, after
consultation with counsel, failure to so disclose would be inconsistent with its
fiduciary duties to Chigen or the holders of Class A Common Stock under
applicable law; provided that Chigen does not, except as permitted by Section
4.03(b), withdraw or modify, or propose to withdraw or modify, its position with
respect to the Amalgamation or approve or recommend, or propose to approve or
recommend, a Takeover Proposal.
 
     (e) For the purposes of determining compliance with the terms of this
Agreement, the parties hereto agree that the failure to take, following receipt
of a Takeover Proposal, an action which the Special Committee reasonably
believes is likely to result in a Superior Proposal would be deemed to be a
breach of the Special Committee's fiduciary duties.
 
     SECTION 4.04.  Access to Information; Confidentiality.  Chigen shall, and
shall cause each of its subsidiaries to, afford to AES, and to AES' officers,
employees, accountants, counsel, financial advisers and other representatives,
reasonable access during normal business hours during the period prior to
Effective Time to all their respective properties, books, contracts,
commitments, personnel and records and, during such period, Chigen shall, and
shall cause each of its subsidiaries to, furnish promptly to AES (a) a copy of
each report, schedule, registration statement and other document filed by it
during such period pursuant to the requirements of federal or state securities
laws and (b) all other information concerning its business, properties and
personnel as AES may reasonably request.
 
     SECTION 4.05.  Reasonable Efforts; Notification.  (a) Upon the terms and
subject to the conditions set forth in this Agreement, each of the parties
agrees to use all reasonable efforts to take, or cause to be taken, all actions,
and to do, or cause to be done, and to assist and cooperate with the other
parties in doing, all things
 
                                      A-13
<PAGE>   110
 
necessary, proper or advisable to consummate and make effective, in the most
expeditious manner practicable, the Amalgamation and the transactions
contemplated hereby, including (i) approvals from Governmental Entities and the
making of all necessary registrations and filings (including filings with
Governmental Entities, if any) and the taking of all reasonable steps as may be
necessary to obtain an approval or waiver from, or to avoid an action or
proceeding by, any Governmental Entity, (ii) the obtaining of all necessary
consents, approvals or waivers from third parties, (iii) the defending of any
lawsuits or other legal proceedings, whether judicial or administrative,
challenging this Agreement or the consummation of any of the transactions
contemplated hereby, including seeking to have any stay or temporary restraining
order entered by any court or other Governmental Entity vacated or reversed and
(iv) the execution and delivery of any additional instruments necessary to
consummate the transactions contemplated hereby, and to fully carry out the
purposes of, this Agreement. In connection with and without limiting the
foregoing, Chigen and its Board of Directors shall (i) take all reasonable
actions to ensure that no state takeover statute or similar statute or
regulation is or becomes applicable to the Amalgamation, this Agreement, or any
of the other transactions contemplated hereby, and (ii) if any state takeover
statute or similar statute or regulation becomes applicable to the Amalgamation,
this Agreement, or the transactions contemplated hereby, take all reasonable
actions to ensure that the Amalgamation and the transactions contemplated hereby
may be consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise to minimize the effect of such statute or regulation on
the Amalgamation, this Agreement and the transactions contemplated hereby.
Notwithstanding the foregoing, Chigen, the Special Committee and the Board of
Directors of Chigen shall not be prohibited from taking any action permitted by
the terms of this Agreement.
 
     (b) Each of the parties shall give prompt notice to the other parties of
(i) any material representation or warranty made by it contained in this
Agreement that is qualified as to materiality becoming untrue or inaccurate in
any respect or any such material representation or warranty that is not so
qualified becoming untrue or inaccurate in any material respect or (ii) the
failure by it to comply with or satisfy in any material respect any material
covenant, condition or agreement to be complied with or satisfied by it under
this Agreement; provided, however, that no such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.
 
     SECTION 4.06.  Employee Benefit Plans.  AES and Chigen agree that any
employee benefit or compensation plans, agreements or arrangements, including
"employee benefit plans" as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), to which Chigen or any
subsidiary of Chigen is a party (together, the "Chigen Benefit Plans") in effect
at the date of this Agreement shall remain in effect until otherwise amended or
terminated after the Effective Time. To the extent the Chigen Benefit Plans are
amended or terminated, it is the current nonbinding intent of the parties that
employee benefit plans which are no less favorable, in the aggregate, than the
Chigen Benefit Plans shall be provided to the employees of Chigen.
Notwithstanding the foregoing, Options shall be treated in the manner provided
in Section 2.05 and the parties shall take all actions necessary and appropriate
to merge the AES China Generating Co. Ltd. Profit Sharing and Employee Stock
Ownership Plan (the "Chigen Profit Sharing Plan") into The AES Corporation
Profit Sharing and Stock Ownership Plan.
 
     SECTION 4.07.  Fees and Expenses.  (a) Except as provided below and in
Section 4.01, all fees and expenses incurred in connection with the
Amalgamation, this Agreement and the transactions contemplated hereby shall be
paid by the party incurring such fees or expenses, whether or not the
Amalgamation is consummated.
 
     (b) Chigen shall pay, or cause to be paid, in same day funds to AES all of
AES's out-of-pocket expenses referred to in Section 4.07(a) in an amount up to
but not to exceed $750,000 (the "Expenses") upon demand if (i) AES terminates
this Agreement under Section 6.01(d) as a result of the occurrence of an event
under clause (ii) or (iii) of Section 6.01(d), (ii) Chigen terminates this
Agreement pursuant to Section 6.01(e) or (iii) prior to the termination of this
Agreement (other than by Chigen pursuant to Section 6.01(f)), a Takeover
Proposal shall have been made and within one year of such termination, Chigen
enters into an agreement with respect to, approves or recommends or takes any
action to facilitate, such Takeover Proposal. The amount of Expenses so payable
shall be the amount set forth in an estimate delivered by AES, subject to
 
                                      A-14
<PAGE>   111
 
upward or downward adjustment (not to be in excess of the amount set forth
above) upon delivery of reasonable documentation therefor.
 
     SECTION 4.08.  Public Announcements.  AES and Chigen will consult with each
other before issuing, and provide each other the opportunity to review and
comment upon, any press release or other public statements with respect to the
transactions contemplated by this Agreement, including the Amalgamation, and
shall not issue any such press release or make any such public statement prior
to such consultation, except as may be required by applicable law, court process
or by obligations pursuant to any listing agreement with any national securities
exchange or national securities quotation system. The parties agree that the
initial press release to be issued with respect to the transactions contemplated
by this Agreement shall be in the form heretofore agreed to by the parties.
 
     SECTION 4.09.  Indemnification; Insurance.  (a) Chigen shall not, and for a
period of six years from and after the Effective Time AES and the Amalgamated
Company shall not, amend the provisions of the Bye-Laws providing for the
indemnification of directors and officers of Chigen in any manner adverse to
such directors and officers.
 
     (b) For a period of six years after the Effective Time, AES shall cause to
be maintained in effect the current policies of directors' and officers'
liability insurance maintained by Chigen (provided that AES may substitute
therefor policies of at least the same coverage and amounts containing terms and
conditions which are no less advantageous) with respect to claims arising from
facts or events which occurred before the Effective Time to the extent
available.
 
     The provisions of this Section 4.09 are intended to be for the benefit of,
and shall be enforceable by, each indemnified party, his or her heirs and
representatives.
 
     SECTION 4.10.  Termination of the Stock Purchase and Shareholder's
Agreement.  Each of the Stock Purchase and Shareholder's Agreement, dated as of
December 29, 1993, by and between AES and Chigen, and the NonCompetition and
Non-Disclosure Agreement, dated as of December 29, 1993, and amended and
restated as of February 1, 1994, by and between AES and Chigen, shall be
terminated as of the Effective Time.

          (e) by AES or Chigen if Chigen enters into a definitive agreement in

          (f) by Chigen in the event of a breach by AES in any material respect
     of any representation, warranty, covenant or other agreement contained in

     failure of a condition set forth in Section 5.03(a) or 5.03(b) and (ii)
     cannot be or has not been cured within 30 days after the giving of written
     notice to AES, except, in any case, such failures which, in the aggregate,
     would not have a Material Adverse Effect in respect of AES.
 
     SECTION 6.02.  Effect of Termination.  In the event of termination of this
Agreement by either Chigen or AES as provided in Section 6.01, this Agreement
shall forthwith become void and have no effect, without any liability or

3.01(i), Section 3.02(g), Section 4.01, Section 4.07, this Section 6.02 and
Article VII and except to the extent that such termination results from the
willful and material breach by a party of any of its representations,
warranties, covenants or agreements set forth in this Agreement.
 
     SECTION 6.03.  Amendment.  This Agreement may be amended by the parties at
any time. This Agreement may not be amended except by an instrument in writing

obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties contained in this Agreement or in any
document delivered pursuant to this Agreement or (c) waive compliance with any
of the agreements or conditions contained in this Agreement. Any agreement on
the part of a party to any such extension or waiver shall be valid only if set
forth in an instrument in writing signed on behalf of such party. The failure of
any party to this Agreement to assert any of its rights under this Agreement or
otherwise shall not constitute a waiver of those rights.
 
     SECTION 6.05.  Procedure for Termination, Amendment, Extension or
Waiver.  A termination of this Agreement pursuant to Section 6.01, an amendment
of this Agreement pursuant to Section 6.03, an extension or waiver pursuant to
Section 6.04, or any other action pursuant to this Agreement shall, in order to
be effective, require, in the case of Chigen, action by the Special Committee,
or action by the duly authorized designee of such Special Committee. Any action

     SECTION 7.01.  Nonsurvival of Representations and Warranties; Effect of
Breach of Representation or Warranty.  (a) None of the representations and
warranties in this Agreement or in any instrument delivered pursuant to this
Agreement shall survive after the Effective Time. This Section 7.01(a) shall not
limit any covenant or agreement of the parties which by its terms contemplates
performance after such date.
 
     (b) For all purposes of this Agreement, Chigen shall be deemed not to have
breached any of its representations and warranties if any senior officer of AES
(other than any such senior officer who is also an officer of Chigen) has
knowledge of such breach at the time this Agreement is delivered by AES. No
party hereto shall have any liability for damages to the other parties for the
breach of any of its representations or warranties contained herein, whether
before or after the Effective Time; it being understood that the other parties'
sole remedy shall be to not consummate the Amalgamation and/or terminate this
Agreement, in either instance in accordance with the terms of this Agreement.
Notwithstanding anything to the contrary contained in the previous sentence,
this Section 7.01(b) shall not limit AES's rights under Section 4.07(b).

                            As of November 12, 1996
 
The Special Committee of the Board of Directors
AES China Generating Co. Ltd.
3/F (W), Golden Bridge Plaza
No. 1 (A) Jianguomenwai Avenue
Beijing 100020, People's Republic of China
 
Gentlemen:
 
     AES China Generating Co., Ltd. (the "Company") and The AES Corporation
("AES") propose to enter into an Agreement and Plan of Amalgamation (the
"Agreement") pursuant to which the Company will be amalgamated with a
wholly-owned subsidiary of AES (the "Amalgamation") in which each outstanding
share (the "Shares") of the Company's Class A common stock, par value $0.01 per
share, will be cancelled and converted into the right to receive (i) 0.29 shares
of the common stock of AES (the "AES Shares") or (ii) should the average closing
price of the AES Shares on the New York Stock Exchange over the 15 consecutive
trading day ending at the close of trading on the third trading day immediately
prior to the date of the special meeting of the Company's shareholders to
consider the Amalgamation (the "Average Closing Price") exceed $50.00 or be less
than $45.00, such fraction of an AES Share (expressed as a decimal rounded to
the nearest one ten-thousandth) as is determined by dividing $13.05 (if the
Average Closing Price is less than $45.00) or $14.50 (if the Average Closing
Price is greater than $50.00) by the Average Closing Price.
 
     You have asked us whether, in our opinion, the proposed consideration to be
received by the holders of the Shares in the Amalgamation is fair to such
holders from a financial point of view.
 
     In arriving at the opinion set forth below, we have, among other things:
 
          (1) Reviewed the Company's Annual Report and Form 10-K (including the
     financial information included therein) for each of the two fiscal years in
     the period ended November 30, 1995, the Company's Form 10-Q (including the
     unaudited financial information included therein) for each of the quarterly
     periods ending August 31, 1996, May 31, 1996 and February 28, 1996, the
     Company's initial public offering prospectus dated February 24, 1994 and
     the Company's Form S-3 Registration Statement dated October 16, 1996;
 
          (2) Reviewed AES' Annual Report and Form 10-K (including the financial
     information included therein) for each of the five fiscal years in the
     period ended December 31, 1995 and AES' Form 10-Q (including the unaudited
     financial information included therein) for each of the quarterly periods
     ending March 31, 1996 and June 30, 1996;
 
          (3) Reviewed certain information, including financial forecasts,
     relating to the business, earnings, cash flow, assets and prospects of the
     Company and AES, furnished to us by the Company and AES;
 
          (4) Conducted discussions with members of senior management of the
     Company and AES concerning their respective businesses and prospects;
 
          (5) Reviewed the historical market prices and trading activity for the
     Shares and the AES Shares and compared them with those of certain publicly
     traded companies which we deemed to be comparable to the Company and AES,
     respectively;
 
          (6) Compared the results of operations of the Company and AES with
     those of certain companies which we deemed to be comparable to the Company
     and AES, respectively;
 
          (7) Compared the proposed financial terms of the Amalgamation with the
     financial terms of certain other mergers and acquisitions which we deemed
     to be relevant;
 
                                       B-1
<PAGE>   120
 
          (8) Reviewed a draft of the Agreement dated November 9, 1996, which
     you have advised us will be identical in all material respects to the
     Agreement as executed; and
 
          (9) Reviewed such other financial studies and analyses and performed
     such other investigations and took into account such other matters as we
     deemed necessary.
 
     In preparing our opinion, we have with your consent relied on the accuracy
and completeness of all information supplied or otherwise made available to us
by the Company and AES, and we have not independently verified such information
or undertaken an independent appraisal of the assets or liabilities of the
Company or AES. With respect to the financial forecasts furnished by the Company
and AES, we have assumed that they have been reasonably prepared and reflect the
best currently available estimates and judgment of the Company's and AES'
management as to the expected future financial performance of the Company or
AES, as the case may be. Our opinion necessarily is based upon market, economic,
financial and other conditions as they exist and can be evaluated as of the date
hereof.
 
     In connection with the preparation of this opinion, we have not been
authorized by the Company, the Board of Directors or the Special Committee of
the Board of Directors to solicit, nor have we solicited, third-party
indications of interest for the acquisition of all or any part of the Company.
 
     We have acted as financial advisor to the Company with respect to the
Amalgamation and will receive a fee from the Company for our services. We have,
in the past, provided financing services to the Company and have received fees
for the rendering of such services. In addition, in the ordinary course of our
business, we or our affiliates may actively trade the Shares and the AES Shares
for our or our affiliates' own account and for the account of customers and,
accordingly, may at any time hold a long or short position in such securities.
 
     On the basis of, and subject to the foregoing, we are of the opinion that
the proposed consideration to be received by the holders of the Shares in the
Amalgamation is fair to such holders from a financial point of view.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Under AES's By-Laws, and in accordance with Section 145 of the Delaware
General Corporation Law (the "GCL"), AES shall indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than any action or suit by or in the right of AES to
procure a judgment in its favor, which is hereinafter referred to as a
"derivative action") by reason of the fact that such person is or was a
director, officer or employee of AES, or is or was serving in such capacity or
as agent at the request of AES for another entity, to the full extent authorized
by Delaware law, against expenses (including, but not limited to, attorneys'
fees), judgments, fines and amounts actually and reasonably incurred in
connection with the defense or settlement of such action, suit or proceeding if
such person acted in good faith and in a manner the person reasonably believed
to be in or not opposed to the best interests of AES, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe was unlawful.
Agents of AES may be similarly indemnified, at the discretion of the Board of
Directors.
 
     Under Section 145 of the GCL, a similar standard of care is applicable in
the case of derivative actions, except that indemnification only extends to
expenses (including attorneys' fees) incurred in connection with the defense or
settlement of such an action and then, where the person is adjudged to be liable
to AES, only if and to the extent that the Court of Chancery of the State of
Delaware or the court in which such action was brought determines that such
person is fairly and reasonably entitled to such indemnity and only for such
expenses as the court shall deem proper.
 
     Pursuant to AES's By-Laws, a person eligible for indemnification may have
the expenses incurred in connection with any matter described above paid in
advance of a final disposition by AES. However, such advances will only be made
upon the delivery of an undertaking by or on behalf of the indemnified person to
repay all amounts so advanced if it is ultimately determined that such person is
not entitled to indemnification.
 
     In addition, under AES's By-Laws, AES may purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of
AES or of another corporation against any liability asserted against and
incurred by such person in such capacity, or arising out of the person's status
as such whether or not AES would have the power or the obligation to indemnify
such person against such liability under the provisions of AES's By-Laws.

ITEM 22.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.
 
     The undersigned registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     The registrant undertakes that every prospectus: (i) that is filed pursuant
to the paragraph immediately preceding, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in
connection with an offering of securities subject to Rule 415, will be filed as
part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.
 
     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of
 
                                      II-2
<PAGE>   123
 
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means.This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.
 
     The undersigned hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

                            MEETINGS OF STOCKHOLDERS

Section 2.01.  Time and Place.  All meetings of stockholders shall be held at
such time and place within or without the State of Delaware as shall be stated
in the notice of the meeting, or in a duly executed waiver of notice thereof.

Section 2.02.  Annual meetings of stockholders shall be held on the first
Friday of June of each year, if not a legal holiday, and if a legal holiday,
then on the next succeeding business day not a legal holiday, or at such other
date and time as shall be designated from time to time by the Board of
Directors and stated in the notice of the meeting. At the annual meeting, the
stockholders shall elect a Board of Directors, and transact any other business
as may properly come before the meeting, notice of which was given in the
notice of the meeting. At each election of directors, every holder of stock
entitled to vote shall have the right to vote, in person or by proxy, the
number of shares owned by him for as many persons as there are directors to be
elected and for whose election he has a right to vote. Directors shall be
elected by a plurality of votes cast at an election.

Section 2.03.  The Secretary shall prepare and make, at least ten days before
every meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each stockholder. Such list shall be open to the examination of any
stockholder, for any purpose germane to the meeting 
<PAGE>   2
during ordinary business hours, for a period of at least ten days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

Section 2.04.  Special meetings of the stockholders, for any purpose or
purposes, unless otherwise prescribed by statute or by the Certificate of
Incorporation, may be called by the Chairman of the Board, the President or by
resolution adopted by a majority of the entire Board of Directors and shall be
called by the Chairman of the Board or the President at the request in writing
of stockholders owning ten percent (10%) or more of the stock of the
Corporation issued and outstanding and entitled to vote. Such request shall
state the purpose or purposes of the proposed meeting.

Section 2.05.  Written notice of the annual meeting or any special meeting of
stockholders stating the place, date and hour of the meeting shall be given in
accordance with Section 4.01 to each stockholder entitled to vote at such
meeting not less than ten nor more than sixty days before the date of the
meeting. 

Section 2.06.  Business transacted at any special meeting of stockholders shall
be limited to the purposes stated in the notice.  

Section 2.07.  The holders of a majority of the stock issued and outstanding
and entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the Certificate of
Incorporation. If, however, such quorum shall not be present or represented at
any meeting of the stockholders, the stockholders entitled to vote thereat,
present in person or represented by proxy, or the officer presiding over the
meeting, shall have power to adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present
or represented. At such adjournment at which a quorum shall be present or
represented any business may be transacted which might have been transacted at
the meeting as originally notified. If the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given in accordance with Section 2.01 or 2.05 as the case may be, to each
stockholder of record entitled to vote at the meeting.

Section 2.08.  At any meeting at which a quorum is present, the vote of the
holders of a majority of the stock entitled 

<PAGE>   3
to vote on the subject matter, present in person or represented by proxy, shall
be the act of the stockholders, unless the subject matter is such that, by
express provision of the statutes, the Certificate of Incorporation or these
By-Laws, a different vote is required, in which case such express provision
shall govern and control the decision of such subject matter. The stockholders
present at a duly convened meeting may continue to transact business until
adjournment, notwithstanding the withdrawal of enough stockholders to leave
less than a quorum.

Section 2.09.  If a vote is to be taken by ballot, each ballot shall state the
number of shares voted and the name of the stockholder or proxy voting.

Section 2.10.  Whenever a vote of stockholders at a meeting thereof is required
or permitted to be taken for or in connection with any corporate action by any
provision of the statutes, the meeting and vote of stockholders may be
dispensed with if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize to take such
action at a meeting at which all shares entitled to vote thereat were present
and voted. Prompt notice of the taking of the corporate action without a
meeting by less than unanimous consent shall be given to those stockholders who
have not consented in writing.

Section 2.11.  Each meeting of the stockholders, whether annual or special,
shall be presided over by the Chairman of the Board if present, and if he or
she is not present or declines to preside by the President if present. If
neither officer specified in the preceding sentence is present, the meeting
shall be presided over by the person designated in writing by the Chairman of
the Board, or if the Chairman of the Board has made no designation, by the
person designated by the President, or if the President has made no
designation, by the person designated by the Board of Directors. If neither
officer specified in the first sentence of this Section 2.11 is present, and no
one designated by the Chairman of the Board or the President or the Board of
Directors is present, the meeting may elect any stockholder of record who is
entitled to vote for directors, or any person present holding a proxy for such
a stockholder, to preside. The Secretary of the Company (or in his or her
absence any Assistant Secretary) shall be the Secretary of any such meeting; in
the absence of the Secretary and Assistant Secretaries, any person may be 
elected by the meeting to act as Secretary of the meeting.

Section 2.12.  Any voting proxy given by a stockholder must be: in writing,
executed by the stockholder, or, in lieu thereof, to the extent permitted by
law, may be transmitted

<PAGE>   4
in a telegram, cablegram or other means of electronic transmission setting
forth or submitted with information from which it can be determined that the
telegram, cablegram or other electronic transmission was authorized by the
stockholder. A copy, facsimile transmission or other reliable reproduction of a
written or electronically-transmitted proxy authorized by this Section 2.12 may
be substituted for or used in lieu of the original writing or electronic
transmission to the extent permitted by law.

Section 2.13.  The directors shall appoint one or more inspectors of election

member at any meeting of the committee. Any such committee, to the extent
provided in the adopting resolution, shall have and may exercise the powers of
the Board of Directors in the management of the business and affairs of the
Corporation except as limited by the General Corporation Law of the State of

objecting and does so object at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or

                                INDEMNIFICATION

<PAGE>   13
Section 8.01. (A) Any person who was or is a party or is threatened to be made a
party to or was or is involved (as a witness or otherwise) in any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than any action or suit by or in the
right of the Corporation to procure a judgment in its favor (a "derivative
action")) by reason of the fact that he or she is or was a director, officer or
employee of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, shall be indemnified by the Corporation, to
the extent authorized by the laws of the State of Delaware as the same exists or
may hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the Corporation to provide broader
indemnification rights than such laws permitted prior to such amendment),
against all expenses (including, but not limited to, attorneys' fees, judgments,
fines, penalties and amounts paid in settlement) actually and reasonably
incurred by him or her in connection with the defense or settlement of such
action, suit or proceeding. In the event of any derivative action, such persons
shall be indemnified by the Corporation under the same conditions and to the
same extent as specified above, except that no indemnification is permitted in
respect of any claim, issue or matter as to which such persons shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper. The indemnification expressly provided by statute
in a specific case shall not be deemed exclusive of any other rights to which
any person indemnified may be entitled under any lawful agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
or her official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

(B) The right to indemnification conferred in this Article VIII is and shall be
a contract right. The right to indemnification conferred in this Article VIII
shall include the right to be paid by the Corporation the expenses (including
attorneys' fees and retainers therefor) reasonably incurred in connection with
any such proceeding in advance of its final disposition, such advances to be
paid by the Corporation within 20 days after the receipt by the

<PAGE>   14
Corporation of a statement or statements from a director, officer or employee of
the Corporation requesting such advance or advances from time to time; provided,
however, the payment of such expenses incurred by a director, officer or
employee in his or her capacity as a director, officer or employee in advance of
the final disposition of a proceeding shall be made only upon delivery to the
Corporation of an undertaking by or on behalf of such director, officer or
employee to repay all amounts so advanced if it shall ultimately be determined
that such director, officer or employee is not entitled to be indemnified under
this Article VIII or otherwise.

(C) To obtain indemnification under this Article VIII, an indemnitee shall
submit to the Corporation a written request, including therein or therewith such
documentation and information as is reasonably available to such person and is
reasonably necessary to determine whether and to what extent the indemnitee is
entitled to indemnification.

(D) The Corporation may maintain insurance, at its expense, to protect itself
and any director, officer, employee or agent of the Corporation or another
corporation, partnership, joint venture; trust or other enterprise including
service with respect to employee benefit plans, against any expense, liability
or loss, whether or not the Corporation would have the power to indemnify such
person against such expense, liability or loss under the General Corporation Law
of the State of Delaware. To the extent that the Corporation maintains any
policy or policies providing such insurance, each such director, officer or
employee, and each such agent to which rights to indemnification have been
granted as provided in paragraph (E) of this Article VIII, shall be covered by
such policy or policies in accordance with its or their terms to the maximum
extent of the coverage thereunder for any such director, officer, employee or
agent.

(E) The Corporation may, to the extent authorized from time to time by the Board
of Directors, grant rights to indemnification, and rights to be paid by the
Corporation the expenses incurred in connection with any proceeding in advance
of its final disposition, to any agent of the Corporation to the fullest extent
of the provisions of this Article VIII with respect to the indemnification and
advancement of expenses of directors, officers and employees of the Corporation.

                                   ARTICLE IX

nominations has been given, either by personal delivery or by United States
mail, postage prepaid, to the Secretary of the Corporation not later than (a)
with respect to an election to be held at an annual meeting of stockholders,
ninety (90) days in advance of such meeting; and (b) with respect to an election

on which notice of such meeting is first given to stockholders and (ii) the date
on which a public announcement of such meeting is first made. Each such notice

or persons to be nominated; (2) a description of all arrangements or
understandings between the stockholder and each nominee and any other person or
persons (naming such person or persons) pursuant to which the nomination or
nominations are to be made by the stockholder; (3) such other information
regarding each nominee proposed by such stockholder as would have been required
to be included in a proxy statement filed pursuant to the proxy rules of the

meeting may refuse to acknowledge the nomination of any person not made in
compliance with the foregoing procedure.

of a majority of the stockholders entitled to vote thereon or a majority of the
directors then in office at any regular meeting of the stockholders or of the
Board of Directors, respectively, or at any special meeting of the stockholders
or of the Board of Directors, respectively, if notice of such proposed
alteration or repeal be contained in the notice of such meeting. The
stockholders may determine by majority vote that any action taken by them with
respect to adoption, amendment or repeal of any part of these By-Laws shall not
be subject to subsequent amendment or repeal by the Board of Directors, provided
that any such determination shall be set forth in the appropriate place in the
text of these By-Laws.

common stock certificate, and originals or copies of such documents,
instruments, records, and certificates of public officials and officers of the
Company as we have deemed necessary. In connection with such examination, we
have assumed the genuineness of all signatures and the authenticity of all
documents submitted to us as copies, and we have also made such other
investigations of fact and law as we have deemed relevant in connection with the
opinion set forth below. In rendering this opinion, we have relied upon the
accuracy of the certificates, documents, instruments, certificates, and records
we have examined as to the matters of fact covered thereby.

                  Based on the foregoing, we are of the opinion that, when the
Registration Statement becomes effective, the Shares, when issued in accordance
with the terms of the Amalgamation Agreement, will be duly and validly issued,
fully-paid and non-assessable.

Statement under the caption "Legal Matters" and we also hereby consent to the
filing of this opinion as an exhibit to the Registration Statement.

Dear Sirs:

                  We have acted as counsel to The AES Corporation ("AES") in
connection with the proposed amalgamation (the "Amalgamation") of AES
Acquisition Co. Ltd., a Bermuda corporation and a wholly-owned subsidiary of AES
("AES Sub") with and into AES China Generating Co. Ltd., a Bermuda corporation
("AES Chigen") upon the terms and subject to the conditions set forth in the
Amended and Restated Agreement and Plan of Amalgamation dated as of November 12,
1996 (the "Amalgamation Agreement").

                  We have assisted in the preparation of the section headed
"Material Tax Consequences - United States Federal Income Taxation" contained 
in the Proxy Statement- Prospectus of AES (the "Proxy Statement-Prospectus") 
filed as

part of the Registration Statement of AES on Form S-4 
(the "Registration Statement").

                  In rendering our opinion we have examined and relied upon the
accuracy and completeness of the facts, information, covenants and
representations contained in originals or copies, certified or otherwise
identified to our satisfaction, of the Amalgamation Agreement, the Proxy
Statement-Prospectus and such other documents as we have deemed necessary or
appropriate as a basis for the opinion set forth below. We have assumed that the
Amalgamation will be consummated in accordance with the Amalgamation Agreement
and as described in the Proxy Statement-Prospectus.

                  In rendering our opinion, we have considered the applicable
provisions of the Internal Revenue Code of 1986, as amended, Treasury
Regulations promulgated thereunder, pertinent judicial authorities, interpretive
rulings of the Internal Revenue Service and such other authorities as we have
considered relevant, in each case as in effect on the date hereof.

                  Based solely on the foregoing, we are of the opinion that the
material United States Federal income tax consequences of the Amalgamation are 
as set forth under the heading "Material Tax  Consequences - United States 
Federal Income Taxation" in the Proxy Statement-Prospectus.  The

United States Federal income tax consequences with respect to a particular
shareowner of AES Chigen may depend upon that shareowner's particular
circumstances and tax situation, and, therefore, the discussion under the
heading "Material Tax Consequences - United States Federal Income Taxation" in
the Proxy Statement-Prospectus may not address all Federal income tax issues
with respect to a particular shareowner.

                  Except as set forth above, we express no opinion as to the tax
consequences, whether Federal, state, local or foreign, of the Amalgamation or
of any transactions related thereto. We hereby consent to the filing of this
opinion with the Securities and Exchange Commission as an exhibit to the
Registration Statement and the reference to our firm under the heading
"Material Tax Consequences - United States Federal Income Taxation". In giving
such consent, we do not thereby admit that we are in the category of persons
whose consent is required under Section 7 of the Securities Act of 1933, as
amended.        




                                                   Very truly yours,
