            SOUTHERN INDIANA GAS AND ELECTRIC COMPANY

           FIRST MORTGAGE BOND, SERIES A 1993 DUE 2028


     This bond is one of an issue of First Mortgage Bonds of
the Company, issuable in series, and is one of the series
designated in the title hereof, all issued and to be issued
under and equally secured (except as to any sinking fund
established in accordance with the provisions of the
Mortgage hereinafter mentioned for the bonds of any
particular series) by an Indenture of Mortgage and Deed of
Trust, dated as of April 1, 1932, executed by the Company to
Bankers Trust Company, as Trustee (the "Trustee"), as
amended and supplemented by indentures supplemental thereto,
including without limitation a Supplemental Indenture dated
as of May 1, 1993, to which Indenture as so amended and
supplemented (herein referred to as the Mortgage) reference
is made for a description of the property mortgaged and
pledged, the nature and extent of the security, the rights
of the holders of the bonds in respect thereof and the terms
and conditions upon which the bonds are secured.

     The Bonds of this series are issued and to be issued in
order to evidence and secure a loan made by the County to
the Company pursuant to a Loan Agreement dated as of May 1,
1993.  In order to provide moneys to fund such loan, the
County has issued the Warrick County Bonds under and
pursuant to the County Indenture.  Payments made by the
 87
Company of principal and interest on the Bonds of this
series are intended to be sufficient to permit payments of
principal and interest to be made on the Warrick County
Bonds.  Upon certain terms and conditions, moneys held under
and pursuant to the County Indenture, including moneys so
held from the proceeds of the sale of the Warrick County
Bonds or earnings on the investment of such proceeds, or
redemption of the Warrick County Bonds shall be credited to
or used for the payment of the Bonds of this series and to
the extent so credited or used shall satisfy a like amount
otherwise due hereunder.

     The Bonds of this series are subject to mandatory
redemption, in whole or in part, as the case may be, on each
date that Warrick County Bonds are to be redeemed.  The
principal amount of the Bonds of this series to be redeemed
on any such date shall be equal to the principal amount of
Warrick County Bonds called for redemption on that date. 
All redemptions of Bonds of this series shall be at 100% of
the principal amount thereof, plus accrued interest to the
redemption date.

     If and whenever the Trustee or the Company is notified
that an event of default has occurred and is continuing
under Section 901(d) of the County Indenture, and provided
that the principal of all Warrick County Bonds then
outstanding and the interest thereon shall have been
declared immediately due and payable, then not later than 2
business days following the occurrence of the foregoing
events, the Company shall, upon not less than 30 days' and
not more than 45 days' prior written notice given in the
manner provided in the Mortgage, call for redemption on a
redemption date selected by it not later than 45 days
following the date of such notice, all of the Bonds of this
series then outstanding, and shall on such redemption date
redeem the same at a price equal to 100% of the principal
amount thereof, together with accrued interest thereon to
the redemption date, except that such requirement or
redemption shall be deemed to be waived if, prior to the
date fixed for such redemption of the Bonds of this series,
such event of default is waived or cured.

     In case a completed default, as defined in the
Mortgage, shall occur, the principal of this bond and all
other bonds of the Company at any such time outstanding
under the Mortgage may be declared or may become due and
payable, upon the conditions and in the manner and with the
effect provided in the Mortgage.  The Mortgage provides that
such declaration may in certain events be waived by the
holders of a majority in principal amount of the bonds
entitled to vote then outstanding.
     
     This bond, subject to the limitations with regard
thereto contained in the County Indenture, is transferable
 88
as prescribed in the Mortgage by the registered owner hereof
in person, or by his duly authorized attorney, at 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 be issued to
the transferee in exchange thereof as provided in the
Mortgage, 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.

     The Bonds of this series are issuable as registered
bonds without coupons in denominations of $1,000 and
authorized multiples thereof.  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 without coupons 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.

     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, office 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 acceptance of this bond and
being likewise waived and released by the terms of the
Mortgage.

     Pursuant to the Mortgage, the holder or owner of this
bond by his acceptance hereof is deemed to have agreed to
amendments to the Mortgage which will eventually permit
certain amendments to the Mortgage with the consent of the
holders of 66-2/3% of the principal amount of the
outstanding bonds of all series issued under the Mortgage
and which redefine, effective at such time as all bonds of
each series of bonds issued under the Mortgage prior to
January 1, 1977 are no longer outstanding, the amounts
required to be spent by the Company under the Mortgage for
the repair, maintenance, renewal and replacement of its
property.

        DESCRIPTION OF BONDS OF THE THIRTY-FIFTH SERIES  

     Section 1.  Bonds of the Thirty-fifth Series shall
mature on the date set forth in the form of bond relating
thereto hereinbefore set forth, shall bear interest at the
rate from time to time borne by the Warrick County Bonds;
provided, however, that in no event shall the rate of
interest borne by the Bonds of the Thirty-fifth Series
exceed 10%.  Such interest, payable semi-annually, on May 1
and November 1 in each year, and all bonds of said series
shall be designated as hereinbefore in the sixth Whereas
clause set forth.  Both principal of and interest on said
bonds shall be payable, to the extent specified in the form
of bond hereinabove set forth, in any coin or currency of
the United States of America which at the time of payment is
legal tender for the payment of public and private debts, at
the office or agency of the Company in the Borough of
Manhattan, The City of New York, N.Y.  Definitive bonds of
said series may 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.  Definitive
registered bonds of the Thirty-fifth Series may be issued in
the denomination of $1,000 and in such other denominations
(in multiples of $1,000) as the Board of Directors of the
Company shall approve, and execution and delivery to the
Trustee for authentication shall be conclusive evidence of
such approval.  In the manner and upon payment of the
charges prescribed in the Indenture, registered bonds
without coupons of said series may be exchanged for a like
aggregate principal amount of fully registered bonds without
coupons of other authorized denominations of the same
series, upon presentation and surrender thereof for
 98
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 12
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 form of the temporary bonds of said series
shall be in substantially the form of the form of registered
bond hereinbefore recited with such appropriate changes
therein as are required on account of the temporary nature
thereof.  Said temporary bonds of said series shall be in
registered form without coupons, registrable as to
principal, and shall be exchangeable for definitive bonds of
said series when prepared.

     The person in whose name any registered bond without
coupons of the Thirty-fifth 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
either at the close of business on the day preceding 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 or on behalf of 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 April 15 or October 15, as the case may
be, next preceding such interest payment date, or, if such
April 15 or October 15 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 or obligated by law
to close, the next preceding day which shall not be a legal
holiday or day on which such institutions are so authorized
or obligated to close.

     Except as provided in this Section, every registered
bond without coupons of the Thirty-fifth Series shall be
dated and shall bear interest as provided in Section 10 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
 99
have no claim against the Company with respect thereto; and
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 bond shall bear
interest from the May 1 or November 1, as the case may be,
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 November 1, 1993, then from
May 1, 1993.

     It is provided in the County Indenture that moneys on
deposit with the County Trustee for redemption of Warrick
County Bonds under certain circumstances shall be credited
to or used for the payment of principal or interest on the
Bonds of the Thirty-fifth Series.  The Company shall notify
the Trustee of all credits to or payments of principal
(whether at maturity, by redemption or by acceleration) and
interest on the Bonds of the Thirty-fifth Series by mailing
a statement to the Trustee on the date of such credit or
payment to the effect that such credit or payment has been
made, and further stating the extent to which the credit or
payment has been made on account of redemption of Warrick
County Bonds or from funds on deposit with the County
Trustee under the County Indenture.  In addition, the
Company shall promptly notify the Trustee of each change in
the interest rate borne by the Warrick County Bonds.

interest borne by the Bonds of the Thirty-sixth Series
exceed 10%.  Such interest, payable semi-annually, on May 1
and November 1 in each year, and all bonds of said series
shall be designated as hereinbefore in the seventh Whereas
clause set forth.  Both principal of and interest on said
bonds shall be payable, to the extent specified in the form
of bond hereinabove set forth, in any coin or currency of
the United States of America which at the time of payment is
legal tender for the payment of public and private debts, at
the office or agency of the Company in the Borough of
Manhattan, The City of New York, N.Y.  Definitive bonds of
said series may 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.  Definitive
registered bonds of the Thirty-sixth Series may be issued in
the denomination of $1,000 and in such other denominations
 100
(in multiples of $1,000) as the Board of Directors of the
Company shall approve, and execution and delivery to the
Trustee for authentication shall be conclusive evidence of
such approval.  In the manner and upon payment of the
charges prescribed in the Indenture, registered bonds
without coupons of said series may be exchanged for a like
aggregate principal amount of fully registered bonds without
coupons 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 12
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 form of the temporary bonds of said series
shall be in substantially the form of the form of registered
bond hereinbefore recited with such appropriate changes
therein as are required on account of the temporary nature
thereof.  Said temporary bonds of said series shall be in
registered form without coupons, registrable as to
principal, and shall be exchangeable for definitive bonds of
said series when prepared.

     The person in whose name any registered bond without
coupons of the Thirty-sixth 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
either at the close of business on the day preceding 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 or on behalf of 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 April 15 or October 15, as the case may
be, next preceding such interest payment date, or, if such
April 15 or October 15 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 or obligated by law

been paid or, if the Company shall be in default with
respect to the interest due on November 1, 1993, then from
