(FORM OF REVERSE OF BOND OF SERIES NNN)


 


This
bond is one of the bonds of the Company issued and to be issued from time to
time under and in accordance with and all secured by an indenture of mortgage
or deed of trust, dated September 1, 1939, from Public Service Company of
Indiana (predecessor of the Company) to The First National Bank of Chicago, as
Trustee, to which Deutsche Bank National Trust Company is successor trustee
(which indenture as amended by all supplemental indentures is hereinafter
referred to as the “Indenture”). Said Trustee or its successor in trust under
the Indenture is hereinafter sometimes referred to as the “Trustee.” Reference
is hereby made to the Indenture for a description of the property mortgaged and
pledged and the nature and extent of the security for said bonds. By the terms
of the Indenture, the bonds secured thereby are issuable in series which may
vary as to date, amount, dates of maturity, rate of interest and in other
respects as in the Indenture provided.


 


This bond is one of a series designated as “Duke
Energy Indiana, Inc. First Mortgage Bonds, Series NNN, 6%, Due August 1,
2039” (hereinafter referred to as the “Bonds of Series NNN”) of the
Company issued under and secured by the Indenture and created by a Sixtieth
Supplemental Indenture, dated as of June 1, 2009 (the “Sixtieth
Supplemental Indenture”), which also amends the Indenture.


 


This
bond evidences and secures a loan made by the IFA to the Company, pursuant to a
Loan Agreement, dated as of June 1, 2009, between the IFA and the Company
(the “Loan Agreement”). In order to obtain funds for such loan, the IFA,
contemporaneously with the issue of this bond, will issue an aggregate
principal amount of Fifty-five Million Dollars ($55,000,000) of its
Environmental Refunding Revenue Bonds, Series 2009B (Duke Energy Indiana, Inc.
Project) (the “IFA Bonds”) under and pursuant to the IFA Indenture. The IFA
Bonds are payable from payments made by the Company of principal of and
interest on this bond and from moneys in the bond fund created under the IFA
Indenture. The obligation of the Company to pay the principal of and interest
on this bond shall be discharged to the extent that any moneys in said bond
fund are available for payments on the IFA Bonds and are directed by the
Company to be applied thereto, all as provided in the Sixtieth Supplemental
Indenture.


 


The
rights and obligations of the Company and of the bearers and registered owners
of bonds may be modified or amended with the consent of the Company by an
affirmative vote of the bearers or registered owners entitled to vote of at
least seventy-five per centum (75%) in principal amount of the bonds then
outstanding at a meeting of bondholders called for the purpose (and by an
affirmative vote of the bearers or registered owners entitled to vote of at
least seventy-five per centum (75%) in principal amount of bonds of any series
affected by such modification or amendment in case one or more, but less than
all, series of bonds are so affected), all in the manner and subject to the
limitations set forth in the Indenture, any consent by the bearer or registered
owner of any bond being conclusive and binding upon such bearer or registered
owner and upon all future bearers or registered owners of such bond,
irrespective of whether or not any notation of such consent is made on such
bond; provided that no such modification or 


 


8

















 


amendment
shall, among other things, extend the maturity or reduce the amount of, or
reduce the rate of interest on, or otherwise modify the terms of the payment of
the principal of, or interest or premium (if any) on this bond, which
obligations are absolute and unconditional, or permit the creation of any lien
ranking prior to or equal with the lien of the Indenture on any of the
mortgaged property.  The Sixtieth
Supplemental Indenture provides that at any time when no bonds issued under the
Indenture prior to the issuance of the “PSI Energy, Inc. First Mortgage
Bonds, Series BBB, 8%, Due July 15, 2009” are outstanding, the
Company reserves the right to amend the Indenture, without the consent or other
action by the holders of the bonds outstanding at that time, to decrease the
seventy-five per centum (75%) vote requirement referred to above to sixty-six
and two-thirds per centum (66-2/3%).


 


The
Bonds of Series NNN are subject to redemption prior to stated maturity as
follows:


 


(a)           Optional Redemption of IFA
Bonds.  In the event that the Company
exercises its option under the Loan Agreement to direct the optional redemption
of the IFA Bonds on or after August 1, 2019, the Bonds of Series NNN
shall be subject to redemption prior to maturity, in a principal amount equal
to the IFA Bonds so redeemed and on such date as the IFA Bonds are redeemed, at
a price equal to 100% of the principal amount thereof, without premium, plus
accrued interest to the redemption date.


 


(b)           Extraordinary Optional
Redemption of IFA Bonds.  In
the event that the Company exercises its option under the Loan Agreement to
direct the extraordinary optional redemption of the IFA Bonds, the Bonds of Series NNN
shall be subject to redemption, in a principal amount equal to the IFA Bonds so
redeemed and on such date as the IFA Bonds are redeemed, at a redemption price
of 100% of the principal amount redeemed, plus accrued and unpaid interest to
the redemption date.


 


(c)           Mandatory Redemption. The Bonds of Series NNN
are subject to mandatory redemption by the Company in whole or in part, as
applicable, at a redemption price of 100% of the principal amount redeemed,
plus accrued and unpaid interest to the redemption date, upon occurrence of any
of the following events:


 


(1)         Upon the occurrence of a Determination of Taxability
(as defined in the IFA Indenture) as to which the IFA Trustee has been notified
by the Company in writing pursuant to the Loan Agreement, the Bonds of Series NNN
are subject to mandatory redemption by the Company, in a principal amount equal
to the IFA Bonds to be redeemed in connection therewith and on such date as the
IFA Bonds are so redeemed; provided, however, that such requirement of
redemption shall be deemed waived, if prior to the date fixed for such
redemption of the Bonds of Series NNN there shall have occurred and be
continuing an event of default (as defined in the Indenture) which affects any
bond of any series outstanding under the Indenture and which event of default
has not been cured or waived prior to such redemption date, it being the intent
of such proviso that, in lieu of such right to redemption, the holder of the
Bonds of Series NNN shall be


 


9

















 


entitled
only to such rights as are available to the holders of bonds of any other
series outstanding under the Indenture in respect of any such event of default.


 


(2)           In the event that the Company is notified in writing
by the IFA Trustee that (i) an event of default under the IFA Indenture
has occurred and is continuing, and (ii) the IFA Trustee has declared the
principal of all the IFA Bonds then outstanding immediately due and payable
pursuant to the IFA Indenture, the Company shall call for redemption, on a
redemption date selected by it not later than forty-five (45) days following
the date on which such notice from the IFA was received by the Company, the
outstanding Bonds of Series NNN, and shall on such redemption date redeem
the same; provided, however, that such requirement of redemption shall be
deemed waived, if prior to the date fixed for such redemption of the Bonds of Series NNN
(x) such event of default is waived or cured as set forth in the IFA
Indenture, or (y) there shall have occurred and be continuing an event of
default (as defined in the Indenture) which affects any bond of any series
outstanding under the Indenture and which event of default has not been cured
or waived prior to such redemption date, it being the intent of such proviso
that, in lieu of such right to redemption, the holder of the Bonds of Series NNN
shall be entitled only to such rights as are available to the holders of bonds
of any other series outstanding under the Indenture in respect of any such
event of default; and in case of any subsequent occurrence or continuance of
the events described in (i) and (ii) of this paragraph, the Company
shall have the same obligation (subject to the same proviso) to redeem the
Bonds of Series NNN.


 


To
comply with its obligations to redeem the Bonds of Series NNN in whole or
in part imposed herein, the Company shall give written notice of the date of
redemption to the Trustee and the IFA Trustee, which date shall be not less
than thirty (30) days nor more than ninety (90) days from the date the notice
is mailed.  No further notice, by
publication or otherwise, shall be required for redemption of the Bonds of Series NNN,
and the requirements of Section 2 of Article VII of the Indenture for
notice by newspaper publication shall not apply to the Bonds of Series NNN.


 


Unless
the Company defaults in payment of the redemption price, on and after any
redemption date, interest will cease to accrue on the Bonds of Series NNN
or portions thereof called for redemption.


 


In
the case of any of certain events of default specified in the Indenture, the
principal of this bond may be declared or may become due and payable prior to
the stated date of maturity hereof in the manner and with the effect provided
in the Indenture.


 


No
recourse shall be had for the payment of the principal of or interest on this
bond, or for any claim based hereon, or otherwise in respect hereof or of the
Indenture, to or against any incorporator, shareholder, officer or director,
past, present or future, of the Company or of any predecessor or successor
company, either directly or through the Company or such predecessor or
successor company, under any constitution or statute or 


 


10

















 


rule of
law, or by the enforcement of any assessment or penalty, or otherwise, all such
liability of incorporators, shareholders, directors and officers being waived
and released by the registered owner hereof by the acceptance of this bond and
being likewise waived and released by the terms of the Indenture.


 


The
Bonds of Series NNN are issuable only in registered form without coupons.
This bond is nontransferable except to the IFA Trustee and successors thereto,
if any, and to the Company. To the extent that this bond is transferable, it is
transferable by the registered owner hereof, in person or by an attorney duly authorized,
at the principal office or place of business of Deutsche Bank National Trust

ARTICLE V.


 


MISCELLANEOUS PROVISIONS.


 


Section 1. Wherever in the original Indenture or in any
of the fifty-nine supplemental indentures thereto reference is made to any
article or section of the original Indenture, such reference shall be deemed to
refer to such article or section as amended by such supplemental indentures.


 


Section 2.  Upon
the execution and delivery hereof, the Indenture shall thereupon be deemed to
be amended as hereinabove set forth as fully and with the same effect as if the
amendments made hereby were set forth in the original Indenture and each of the
fifty-nine supplemental indentures to the Indenture shall henceforth be read,
taken and construed as one and the same instrument; but such amendments shall
not operate so as to render invalid or improper any action heretofore taken
under the original Indenture or said supplemental indentures.


 


Section 3. All the covenants, stipulations and
agreements in this Sixtieth Supplemental Indenture contained are and shall be
for the sole and exclusive benefit of the parties hereto, their successors and
assigns, and of the holders from time to time of the bonds.


 


Section 4.  The
table of contents to, and the headings of the different articles of, this
Sixtieth Supplemental Indenture are inserted for convenience of reference, and
are not to be taken to be any part of the provisions hereof, nor to control or
affect the meaning, construction or effect of the same.


 


Section 5.  This
Sixtieth Supplemental Indenture may be simultaneously executed in any number of
counterparts, and all such counterparts shall constitute but one and the same
instrument.


 


Section 6. 
Whenever a payment of principal or interest in respect of the Bonds of Series NNN
are due on any day other than a business day (as hereinafter defined), such
payment shall be payable on the first business day next following such date,
and, in the case of a principal payment, interest on such principal payment
shall accrue to the date of such principal payment. For the purposes of this Section 6
the term business day shall mean any day other than a day on which the Trustee
is authorized by law to close.
