          As more fully described in the Supplemental Indenture establishing
the terms and provisions of the bonds of this series, the Company reserves

          The redemption provisions applicable to the bonds of this series

_____________________________________________________________________________
________________

          The bonds of this series are issuable as registered bonds without
coupons in denominations of $1,000 and authorized multiplies of $1,000.  In
the manner and upon payment of the charges prescribed in the Mortgage,
registered bonds without coupons of this series may be exchanged for a like
aggregate principal amount of fully registered bonds of other authorized
denominations of the same series, upon presentation and surrender thereof,
for cancellation, to the Trustee at its principal corporate trust office in

          This bond is transferable as prescribed in the Mortgage by the

office or agency of the Company in the Borough of Manhattan, The City of New
York, N. Y., upon surrender and cancellation of this bond, and, thereupon, a
new fully registered bond of the same series for a like principal amount will

and upon payment, if the Company shall require it, of the charges therein
prescribed.  The Company and the Trustee may deem and treat the person in
whose name this bond is registered as the absolute owner for the purpose of
receiving payment of or on account of the principal and interest due hereon
and for all other purposes.

          No recourse shall be had for the payment of the principal of or
interest on this bond against any incorporator or any past, present or future
subscriber to the capital stock, stockholder, officer or director of the
Company or of any predecessor or successor corporation, either directly or
through the Company or any predecessor or successor corporation, under any
rule of law, statute or constitution or by the enforcement of any assessment
or otherwise, all such liability of incorporators, subscribers, stockholders,
officers and directors being released by the holder or owner hereof by the

          Bonds of this series are to be issued initially under a book-entry
only system and, except as hereinafter provided, registered in the name of
The Depository Trust Company, New York, New York ("DTC") or its nominee,
which shall be considered to be the holder of all of bonds of this series for
all purposes of the Mortgage, including, without limitation, payment by the
Company of principal of and interest on such bonds of this series and receipt
of notices and exercise of rights of holders of such bonds of this series. 
There shall be a single bond of this series which shall be immobilized in the
custody of DTC with the owners of book-entry interests in bonds of this
series ("Book-Entry Interests") having no right to receive bonds of this
series in the form of physical securities or certificates.  Ownership of
Book-Entry Interests shall be shown by book-entry on the system maintained
and operated by DTC, its participants (the "Participants") and certain
persons acting through the Participants.  Transfers of ownership of Book-
Entry Interests are to be made only by DTC and the Participants by that book-
entry system, the Company and the Trustee having no responsibility therefor
so long as bonds of this series are registered in the name of DTC or its
nominee.  DTC is to maintain records of the positions of Participants in
bonds of this series, and the Participants and persons acting through
Participants are to maintain records of the purchasers and owners of Book-
Entry Interests.  If DTC or its nominee determines not to continue to act as
a depository for the bonds of this series in connection with a book-entry
only system, another depository, if available, may act instead and the single
bond of this series will be transferred into the name of such other
depository or its nominee, in which case the above provisions will continue
to apply but to the new depository.  If the book-entry only system for bonds
of this series is discontinued for any reason upon surrender and cancellation
of the single bond of this series registered in the name of the then
depository or its nominee, new registered bonds of this series will be issued
in authorized denominations to the holders of Book-Entry Interests in
principal amounts coinciding with the amounts of such Book-Entry Interests
shown on the book-entry system immediately prior to the discontinuance
thereof.  Neither the Trustee nor the Company shall be responsible for the
accuracy of the interests shown on that system.  

          This bond shall not become obligatory until Bankers Trust Company,
the Trustee under the Mortgage, or its successor thereunder, shall have
signed the form of certificate endorsed hereon.

otherwise set forth in a Resolution.  Both principal of and interest on the
bonds shall be payable in lawful money of the United States of America at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, N. Y.

          Definitive bonds of the Medium Term Note A Series will be issued,
originally or otherwise, only as registered bonds without coupons; and they
and the Trustee's certificate of authentication shall be substantially in the
forms hereinbefore recited, respectively.  Registered bonds of the Medium
Term Note A Series may be issued in any one or more denominations of $1,000
and authorized multiples of $1,000. In the manner and upon payment of the
charges prescribed in the Indenture, registered bonds without coupons of a
particular series of bonds of the Medium Term Note A Series may be exchanged
for a like aggregate principal amount of fully registered bonds of other
authorized denominations of the same series, upon presentation and surrender
thereof for cancellation, to the Trustee at its principal corporate trust
office in the Borough of Manhattan, The City of New York, N. Y.  However,
notwithstanding the provisions of Section 14 of the Indenture, no charge
shall be made upon any transfer or exchange of bonds of said series other
than for any tax or taxes or other governmental charge required to be paid by
the Company.

          The person in whose name any registered bond without coupons of the
Medium Term Note A Series is registered at the close of business on any
record date (as hereinbelow defined) with respect to any interest payment
date shall be entitled to receive the interest payable on such interest
payment date notwithstanding the cancellation of such registered bond upon
any transfer or exchange thereof subsequent to the record date and prior to
such interest payment date, except if and to the extent the Company shall
default in the payment of the interest due on such interest payment date, in
which case such defaulted interest shall be paid to the person in whose name
such bond is registered on the date of payment of such defaulted interest or
on a subsequent record date for such payment if one shall have been
established as hereinafter provided.  A subsequent record date may be
established by the Company by notice mailed to the holders of bonds not less
than ten days preceding such record date, which record date shall be not more
than thirty days prior to the subsequent interest payment date.  The term
"record date" as used in this Section with respect to any regular interest
payment date shall mean the fifteenth day prior to such interest payment
date, or, if such fifteenth day shall be a legal holiday or a day on which
banking institutions in the Borough of Manhattan, The City of New York, N.
Y., are authorized by law to close, the next preceding day which shall not be
a legal holiday or a day on which such institutions are so authorized to
close.  

          Except as provided in this Section, every registered bond without
coupons of the Medium Term Note A Series shall be dated and shall bear
interest as provided in Section 12 of the Indenture; provided, however, that,
so long as there is no existing default in the payment of interest on the
bonds, the holder of any bond authenticated by the Trustee between the record
date for any interest payment date and such interest payment date shall not
be entitled to the payment of the interest due on such interest payment date
and shall have no claim against the Company with respect thereto; provided,
further, that, if and to the extent the Company shall default in the payment
of the interest due on such interest payment date, then any such bonds shall
bear interest from the interest payment date next preceding the date of such
bond, to which interest has been paid or, if the Company shall be in default
with respect to the interest due on the first interest payment date therefor,
then from the original date of issuance thereof.

          Bonds of any particular series of the Medium Term Note A Series
shall not be redeemable prior to their maturity unless a Resolution is
adopted specifying that the bonds of such series are redeemable prior to
their maturity and the circumstances under which such redemption may or shall
take place.  If redemption terms are established for any series of the Medium
Term Note A Series, such terms shall be set forth on each bond of that series
prior to the issuance thereof.  Redemption of any bonds of the Medium Term
Note A Series shall be in the manner provided in Article X of the Indenture,
upon notice given by mailing the same to the holders of bonds not less than
thirty days and not more than forty-five days prior to the date of
redemption, at the principal amounts of the bonds so to be redeemed and
accrued interest to the date of redemption.

          If applicable to the redemption provisions established for bonds of
the Medium Term Note A Series, the term "maintenance provisions of the
Indenture" shall mean the provisions of Section 43 of the Indenture; and the
term "proceeds of property released pursuant to the provisions of Section 68
of the Indenture" shall mean the proceeds of any of the mortgaged and pledged
property taken by exercise of the power of eminent domain or purchased by any
governmental body or agency in the exercise of any right which it may have to
purchase any part of the mortgaged and pledged property and which shall have
been paid over to the Trustee pursuant to the provisions of Section 68 of the
Indenture, including any cash received by the Trustee on account of the
principal of any obligations secured by purchase money mortgage upon any
property so taken or purchased.
 
          SECTION 3  The Company reserves the right, without any consent or
other action by holders of the bonds of the Twenty-eighth Series or any
series of the Medium Term Note A Series, or any subsequent series of bonds,
to amend the Indenture by inserting the following language as Section 115A
immediately following current Section 115 of the Indenture:

          "SECTION 115A.  With the consent of the holders of not less than
     sixty per centum (60%) in principal amount of the bonds at the time
     outstanding or their attorneys-in-fact duly authorized, or, if the
     rights of the holders of one or more, but not all, series then
     outstanding are affected, the consent of the holders of not less than
     sixty per centum (60%) in aggregate principal amount of the bonds at the
     time outstanding of all affected series, taken together, and not any
     other series, the Company, when authorized by a resolution, and the
     Trustee may from time to time and at any time enter into an indenture or
     indentures supplemental hereto for the purpose of adding any provisions
     to or changing in any manner or eliminating any of the provisions of
     this Indenture or of any supplemental indenture or modifying the rights
     and obligations of the Company and the rights of the holders of any of
     the bonds and coupons; provided, however, that no such supplemental
     indenture shall (1) extend the maturity of any of the bonds or reduce
     the rate or extend the time of payment of interest thereon, or reduce
     the amount of the principal thereof, or reduce any premium, payable on
     the redemption thereof or change the coin or currency in which any bond
     or interest thereon is payable, without the consent of the holder of
     each bond so affected, or (2) permit the creation of any lien, not
     otherwise permitted, prior to or on a parity with the lien of this
     Indenture, without the consent of the holders of all the bonds then
     outstanding, or (3) reduce the aforesaid percentage of the principal
     amount of bonds the holders of which are required to approve any such
     supplemental indenture, without the consent of the holders of all the
     bonds then outstanding.  For the purposes of this Section, bonds shall
     be deemed to be affected by a supplemental indenture if such
     supplemental indenture adversely affects or diminishes the rights of
     holders thereof against the Company or against its property.

          Upon the written request of the Company, accompanied by a
     resolution authorizing the execution of any such supplemental indenture,
     and upon the filing with the Trustee of evidence of the consent of
     bondholders as aforesaid (the instrument or instruments evidencing such
     consent to be dated within one year of such request), the Trustee shall
     join with the Company in the execution of such supplemental indenture
     unless such supplemental indenture affects the Trustee's own rights,
     duties or immunities under this Indenture or otherwise, in which case
     the Trustee may in its discretion but shall not be obligated to enter
     into such supplemental indenture.  The Trustee shall be entitled to
     receive and, subject to Section 102 of the Indenture and Article Four of
     the Supplemental Indenture dated as of April 1st, 1940, may rely upon,
     an opinion of counsel as conclusive evidence that any such supplemental
     indenture is authorized or permitted by the provisions of this Section.

          It shall not be necessary for the consent of the bondholders under
     this Section to approve the particular form of any proposed supplemental
     indenture, but it shall be sufficient if such consent shall approve the
     substance thereof.

          The Company and the Trustee, if they so elect, and either before or
     after such 60% or greater consent has been obtained, may require the
     holder of any bond consenting to the execution of any such supplemental
     indenture to submit his bond to the Trustee or to such bank, banker or
     trust company as may be designated by the Trustee for the purpose, for
     the notation thereon of the fact that the holder of such bond has
     consented to the execution of such supplemental indenture, and in such
     case such notation, in form satisfactory to the Trustee, shall be made
     upon all bonds so submitted, and such bonds bearing such notation shall
     forthwith be returned to the persons entitled thereto.  All subsequent
     holders of bonds bearing such notation shall be deemed to have consented
     to the execution of such supplemental indenture, and consent, once given
     or deemed to be given, may not be withdrawn.

          Prior to the execution by the Company and the Trustee of any
     supplemental indenture pursuant to the provisions of this Section, the
     Company shall publish a notice, setting forth in general terms the
     substance of such supplemental indenture, at least once in one daily
     newspaper of general circulation in each city in which the principal of
     any of the bonds shall be payable, or, if all bonds outstanding shall be
     registered bonds without coupons or coupon bonds registered as to
     principal, such notice shall be sufficiently given if mailed, first
     class, postage prepaid, and registered if the Company so elects, to each
     registered holder of bonds at the last address of such holder appearing
     on the registry books, such publication or mailing, as the case may be,
     to be made not less than thirty days prior to such execution.  Any
     failure of the Company to give such notice, or any defect therein, shall
     not, however, in any way impair or affect the validity of any such
     supplemental indenture."

          SECTION 4.  As supplemented and amended by this Supplemental
Indenture, the Indenture is in all respects ratified and confirmed, and this
Supplemental Indenture and all the terms and conditions herein contained
shall be deemed a part thereof.

          SECTION 5.  Except as herein otherwise expressly provided, no
duties, responsibilities or liabilities are assumed, or shall be construed to
be assumed, by the Trustee by reason of this Supplemental Indenture, other
than as set forth in the Indenture as heretofore amended and supplemented.
The Trustee shall not be responsible for the recitals herein or in the bonds
(other than in the authentication certificate of the Trustee), all of which
are made by the Company solely.

          SECTION 6.  This Supplemental Indenture may be executed in several 
counterparts and all such counterparts executed and delivered, each as an
original, shall constitute but one and the same instrument.

          IN WITNESS WHEREOF, CENTRAL ILLINOIS LIGHT COMPANY, party of the
first part hereto, and BANKERS TRUST COMPANY, party of the second part
hereto, have caused these presents to be executed in their respective names
by their respective Presidents or one of their Vice Presidents or one of
their Assistant Vice Presidents or their respective Treasurers and their
respective seals to be hereunto affixed and attested by their respective
Secretaries or one of their Assistant Secretaries or, in the case of the
Trustee, by  one of their Assistant Treasurers, all as of the day and year
first above written.
