General and Business Corporation Law, or the MGBCL, contains certain
provisions, including business combination provisions that would be applicable
to certain mergers, share exchanges or sales of substantially all assets
involving the Company or a subsidiary and a significant shareholder and which
could have the effect of substantially increasing the cost to the acquiror and
thus discouraging any such transaction.&nbsp;&nbsp;The MGBCL permits
shareholders to adopt an amendment to the articles of incorporation opting out
of the business combination provisions, and the Company&#146;s restated articles of
incorporation opt out of such provisions.</font></p>

Utilities Act, approval of the Illinois Commerce Commission is required for any
transaction which, regardless of the means by which it is accomplished, results
in a change in the ownership of a majority of the voting capital stock of an
Illinois public utility or the ownership or control of any entity which owns or
controls a majority of the voting capital stock of a public
utility.&nbsp;&nbsp;Because the Company controls a majority of the voting stock
of Central Illinois Public Service Company, doing business as AmerenCIPS,
Central Illinois Light Company, doing business as AmerenCILCO and Illinois
Power Company, doing business as AmerenIP, each a public utility subject to
Illinois utility regulation, any change in the Company&#146;s ownership or control,
within the meaning of the Illinois Public Utilities Act, would require Illinois
Commerce Commission approval.&nbsp;&nbsp;Certain acquisitions by any person of
our outstanding voting shares would also require approval under the Federal
Power Act and the Atomic Energy Act of 1954, as amended.</font></p>

officer or director has been adjudged to have been liable to the Company if
such person acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company.&#160; However, no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable for negligence or misconduct in the performance of his
duty to the Company unless and only to the extent that the court in which the
action or suit was brought determines upon application that, despite the
adjudication of liability and in view of all the circumstances of the case, the

pursuant to the provisions described under Item&nbsp;6 above, or otherwise, the
Company has been advised that in the opinion of the SEC such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable.&#160; In the event
that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company 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 Company 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.</p>

Item 4.
Description
of Securities.
General
The following
descriptions of the Company's common stock and the relevant provisions of its
restated articles of incorporation and By-laws are summaries and are qualified
by reference to its restated articles of incorporation and By-laws which have
been previously filed with the Securities and Exchange Commission, as well as
the applicable Missouri General and Business Corporation Law.
Under the Company's
restated articles of incorporation, the Company is authorized to issue
400 million shares of common stock, $.01 par value per share, and
100 million shares of preferred stock, $.01 par value per
share.  As of February 15, 2009, approximately 212,646,273
shares of common stock and no shares of preferred stock were outstanding.
Dividend
Rights and Limitations
The
holders of the Company's common stock are entitled to receive such dividends as
its board of directors may from time to time declare, subject to any rights of
the holders of its preferred stock, if any is issued.  The Company's
ability to pay dividends depends primarily upon the ability of its subsidiaries
to pay dividends or otherwise transfer funds to it.  Various
financing arrangements, charter provisions and regulatory requirements may
impose certain restrictions on the ability of the Company's subsidiaries to
transfer funds to it in the form of cash dividends, loans or advances.
Voting
Rights
Except
as otherwise provided by law and subject to the voting rights of holders of the
Company's preferred stock, if any is issued, the holders of the Company's
common stock have the exclusive right to vote for the election of directors and
for all other purposes.  Each holder of the Company's common stock is
entitled to one vote per
II-1
share on all matters submitted to a vote at a meeting
of shareholders, including the election of directors, which means that the
holders of more than 50% of the shares voting for the election of directors can
elect 100% of the directors and the holders of the remaining shares voting for
the election of directors will not be able to elect any
directors.  The common stock shall vote together as a single
class.  The holders of the Company's common stock are not entitled to
cumulate votes for the election of directors.  At annual and special
meetings of shareholders, a majority of the outstanding shares of common stock
constitutes a quorum.
Liquidation
Rights
In the
event of any liquidation, dissolution or winding up of the Company's affairs,
voluntarily or involuntarily, the holders of the Company's common stock will be
entitled to receive the remainder, if any, of the Company's assets after the
payment of all its debts and liabilities and after the payment in full of any
preferential amounts to which holders of any preferred stock may be entitled.
Uncertificated Shares and Certificates of Stock
The
interest of each shareholder of any class of stock of the Company shall not be
evidenced by certificates for shares and all shares of all classes of stock
shall be uncertificated shares; provided, however,
that (a) any shares of stock of the Company
represented by a certificate shall continue to be represented by such
certificate until such certificate is surrendered to the Company and (b) the
Company may, at its option but without obligation, issue certificates for some
or all of any shares of some or all of any classes of stock as determined by
the Company from time to time.
Miscellaneous
The outstanding shares of
common stock are fully paid and nonassessable.  The holders of the
Company's common stock are not entitled to any preemptive or preferential
rights to subscribe for or purchase any part of any new or additional issue of
stock or securities convertible into stock.  The Company's common
stock does not contain any redemption provisions or conversion rights.
Transfer
Agent and Registrar
Ameren
Services Company, a subsidiary of the Company, acts as transfer agent and
registrar for the common stock.
Certain
Anti-Takeover Matters
The
Company's restated articles of incorporation and By-laws include a number of
provisions that may have the effect of discouraging persons from acquiring
large blocks of its stock or delaying or preventing a change in its
control.  The material provisions that may have such an effect
include:
·
authorization
for the Company's board of directors (subject to any required regulatory
approval) to issue the Company's preferred stock in series and to fix rights
and preferences of the series (including, among other things, whether, and to
what extent, the shares of any series will have voting rights and the extent of
the preferences of the shares of any series with respect to dividends and other
matters);
·
advance
notice procedures with respect to nominations of directors or proposals other
than those adopted or recommended by the Company's board of directors;
·
the
prohibition of shareholder action by less than unanimous written consent
without a meeting; and
·
provisions
specifying that only the chief executive officer or the board of directors (by
a majority vote of the entire board of directors) may call special meetings of
shareholders, and that the chairman of the meeting may adjourn a meeting of shareholders
from time to time, whether or not a quorum is present.
II-2
In addition, the Missouri
General and Business Corporation Law, or the MGBCL, contains certain
provisions, including business combination provisions that would be applicable
to certain mergers, share exchanges or sales of substantially all assets
involving the Company or a subsidiary and a significant shareholder and which
could have the effect of substantially increasing the cost to the acquiror and
thus discouraging any such transaction.  The MGBCL permits
shareholders to adopt an amendment to the articles of incorporation opting out
of the business combination provisions, and the Company's restated articles of
incorporation opt out of such provisions.
Under the Illinois Public
Utilities Act, approval of the Illinois Commerce Commission is required for any
transaction which, regardless of the means by which it is accomplished, results
in a change in the ownership of a majority of the voting capital stock of an
Illinois public utility or the ownership or control of any entity which owns or
controls a majority of the voting capital stock of a public
utility.  Because the Company controls a majority of the voting stock
of Central Illinois Public Service Company, doing business as AmerenCIPS,
Central Illinois Light Company, doing business as AmerenCILCO and Illinois
Power Company, doing business as AmerenIP, each a public utility subject to
Illinois utility regulation, any change in the Company's ownership or control,
within the meaning of the Illinois Public Utilities Act, would require Illinois
Commerce Commission approval.  Certain acquisitions by any person of
our outstanding voting shares would also require approval under the Federal
Power Act and the Atomic Energy Act of 1954, as amended.
Item 5.
Interests of
Named Experts and Counsel.
Ronald
K. Evans, Esq., Vice President and Deputy General Counsel of Ameren
Services Company, a Missouri corporation and a subsidiary of the Company, will pass
upon the validity of the offered securities. 
As of February 15, 2009, Mr. Evans owned 5,132 shares of the
Company's common stock.  In addition, as
of that date, Mr. Evans owned 1,103 restricted shares of the Company's
common stock, 450 of which were vested but not yet released, and has been
awarded 7,093 performance share units under the Ameren Corporation Long-Term
Incentive Plan of 1998 and the Ameren Corporation 2006 Omnibus Incentive
Compensation Plan, 6,452 of which are subject to meeting performance targets.
Item 6.
Indemnification
of Directors and Officers.
Article IV of the Company's By-laws, consistent
with the applicable provisions of the MGBCL, provides for indemnification of
directors and officers.  These provisions
provide that any person shall be indemnified for expenses and liabilities
imposed upon such person in connection with any threatened, pending or
completed action, suit, or proceeding, whether civil, criminal, administrative
or investigative, other than an action by or in the right of the Company, by
reason of the fact that such person is or was a director, officer, employee or
agent of the Company, or is or was serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses, including attorneys'
fees, judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding if
such person acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of the Company, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful.
In a proceeding brought by or in the right of the
Company, indemnification shall be made with respect to any claim as to which an
officer or director has been adjudged to have been liable to the Company if
such person acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company.  However, no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable for negligence or misconduct in the performance of his
duty to the Company unless and only to the extent that the court in which the
action or suit was brought determines upon application that, despite the
adjudication of liability and in view of all the circumstances of the case, the
person is fairly and reasonably entitled to indemnity for such expenses which
the court shall deem proper.
The Company's By-laws, consistent with the applicable
provisions of the MGBCL, provide that indemnification shall be made by the
Company only if a determination has been made by a majority vote of a quorum of
the disinterested directors or by the shareholders or by independent legal
counsel, that the director or officer met the required standard of conduct.
II-3
The Company's By-laws, consistent with the applicable
provisions of the MGBCL, further provide that, in addition to the indemnities
described in the preceding paragraphs, the Company will further indemnify its
officers and directors to the maximum extent permitted by law, provided that no
indemnity may be given for conduct that is adjudged to be knowingly fraudulent,
deliberately dishonest, or willful misconduct.
The Company has purchased insurance on behalf of its
officers and directors which insures them against certain liabilities and
expenses, including those that may arise under the Securities Act of 1933.

UNDERTAKING:
The Company hereby undertakes that it has
submitted the Plan and will submit any amendment thereto to the Internal
Revenue Service in a timely manner and has made or will make all changes
required by the Internal Revenue Service in order to qualify the plan.
Item 9.
Undertakings.
a.     The undersigned hereby undertakes:
(1)
To file,
during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
II-4
(i)
To
include any prospectus required by Section 10(a)(3) of the Securities
Act of 1933;
(ii)
To
reflect in the prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental
change in the information set forth in the registration statement.  Notwithstanding the foregoing, any increase
or decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if,
in the aggregate, the changes in volume and price represent no more than a 20
percent change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;
and
(iii)
To include any material information with respect
to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement,
provided,
however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed with or
furnished to the SEC by the Company pursuant to Section 13 or Section 15(d) of
the Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.
(2)
That,
for the purpose 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.
(3)
To
remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the
offering.
b.
That, for purposes
of determining any liability under the Securities Act of 1933, each filing of
the Company's annual report pursuant to Section 13(a) or Section 15(d) of
the Securities Exchange Act of 1934 and each filing of the Plan's annual report
pursuant to Section 15(d) of the Securities Act of 1933 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.
c.
Insofar as
indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the Company
pursuant to the provisions described under Item 6 above, or otherwise, the
Company has been advised that in the opinion of the SEC 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 Company of expenses incurred or paid by a director, officer or
controlling person of the Company 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 Company 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.
