W I T N E S S E T H




     WHEREAS, Duke Energy has heretofore entered into the Senior Indenture, dated as of September

     WHEREAS, Duke Energy currently has issued and Outstanding the notes of the series listed on
Schedule A hereto (collectively, the “Notes”) under the Indenture;

Act (“NCBCA”), whereby Duke Energy shall be the surviving corporation in the Duke Energy Merger and

assume all the rights and obligations of Merger Sub A in accordance with the NCBCA and, as a result
of the Duke Energy Merger, shall be a direct, wholly-owned subsidiary of Duke Holdco;



     WHEREAS, following effectiveness of the Duke Energy Merger, Duke Energy shall convert its form

Energy Merger, the “Duke Energy Reorganization”);



     WHEREAS, Duke Energy is currently the direct owner of 100% of the issued and outstanding

     WHEREAS, following effectiveness of the Duke Energy Reorganization, Duke Energy shall
distribute to Duke Holdco all the issued and outstanding equity interests of Duke Capital (the
“Duke Capital Distribution”) and, as a result, each of Duke Energy and Duke Capital shall be a
direct, wholly-owned subsidiary of Duke Holdco;



 









 





     WHEREAS, in connection with the Duke Capital Distribution, Duke Holdco desires to fully and
unconditionally guarantee the payment obligations of Duke Energy with respect to the Notes as long
as the Notes remain Outstanding;



     WHEREAS, Section 901(9) of the Original Indenture provides, among other things, that Duke
Energy, when authorized by a Board Resolution, and the Trustee, at any time and from time to time,
may enter into an indenture supplemental to the Original Indenture for the purpose of making any
provisions with respect to matters arising under the Indenture, provided that such action does not
adversely affect the interests of the Holders of Securities of any series in any material respect;



     WHEREAS, the execution of the Fifteenth Supplemental Indenture is authorized and permitted by
Section 901 of the Original Indenture and all conditions precedent provided for in the Indenture
relating to the execution of the Fifteenth Supplemental Indenture have been complied with; and



     WHEREAS, this Fifteenth Supplemental Indenture is being executed prior to the closing of the
transactions contemplated by the Merger Agreement, including the Duke Energy Merger and the Duke
Energy Reorganization, and shall be effective simultaneously with the Duke Capital Distribution.



     NOW, THEREFORE, in consideration of the foregoing and for other good and valuable
consideration, the receipt of which is hereby acknowledged, Duke Energy, Duke Holdco and the
Trustee mutually covenant and agree for the equal and ratable benefit of the Holders from time to
time of the Notes (the “Holders”) as follows:



     Section 101. Capitalized Terms. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Original Indenture.



     Section 102. Guarantee. Duke Holdco does hereby fully and unconditionally guarantee
for the benefit of the Holders and the Trustee (the “Guarantee”) (a) the due and punctual payment
of the principal of, premium, if any, and interest on, all the Notes, whether at Stated Maturity,
by declaration of acceleration, call for redemption or otherwise, the due and punctual payment of
interest on overdue principal of, premium, if any, and interest on all the Notes, if any, if
lawful, and the due and punctual performance of all other obligations of Duke Energy to the Holders
or the Trustee in accordance with the terms of the Indenture, and (b) in case of any extension of
time of payment or renewal of any Notes or any such other obligations, that the same will be
promptly paid in full when due or performed in accordance with the terms of the extension or
renewal, whether at stated maturity, by acceleration or otherwise.



     In case of the failure of Duke Energy to punctually make any such principal, premium, if any,
or interest payment, Duke Holdco hereby agrees to cause any such payment to be made promptly when
and as the same shall become due and payable, whether at Stated Maturity, by declaration of
acceleration, call for redemption or otherwise, and as if such payment were made by Duke Energy.



     Duke Holdco hereby agrees that its obligations under the Guarantee shall be as if it were
principal debtor and not merely surety, and shall be absolute and unconditional, irrespective of,
and shall be unaffected by, any invalidity, irregularity or unenforceability of any Note of any
series or the Indenture, any failure to enforce the provisions of any Note of any series or this
Indenture, or any waiver, modification or indulgence granted to Duke Energy with respect thereto,
by the Holder of any Note of any series or the Trustee, or any other circumstance which may
otherwise constitute a legal or equitable discharge of a surety or guarantor; provided, however,
that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the
consent of Duke Holdco, increase the principal amount of a Note or the interest rate thereon or
increase any premium payable upon redemption thereof.



2









 




Duke Holdco hereby waives diligence, presentment, demand of payment, filing of claims with a
court in the event of a merger or bankruptcy of Duke Energy, any right to require a proceeding
first against Duke Energy, protest or notice with respect to any Note or the indebtedness evidenced
thereby or with respect to any sinking fund payment required pursuant to the terms of a Note issued
under the Indenture and all demands whatsoever, and covenants that the Guarantee will not be
discharged with respect to any Note except by payment in full of the principal of (and premium, if
any) and interest on such Note. The Guarantee shall constitute a guarantee of payment and not of
collection and shall not be impaired by the failure to endorse evidence of the Guarantee on any
Note.




     Duke Holdco shall be subrogated to all rights of the Holder of a Note against Duke Energy in
respect of any amounts paid to such Holder by Duke Holdco pursuant to the provisions of the
Guarantee; provided, however, that Duke Holdco shall not be entitled to enforce, or to receive any
payments arising out of or based upon, such right of subrogation until the principal of (and
premium, if any) and interest on all Notes of the relevant series shall have been paid in full.



     Section 103. Limitation on Liens. Duke Holdco will not, while any of the Notes
remains Outstanding, create or suffer to be created or to exist, any mortgage, lien, pledge,
security interest or other encumbrance of any kind upon any property of Duke Holdco, whether now
owned or hereafter acquired, to secure any indebtedness for borrowed money of Duke Holdco, unless
it shall make effective provisions whereby the Notes then Outstanding shall be secured by such
mortgage, lien, pledge, security interest or other encumbrance equally and ratably with any and all
indebtedness for borrowed money thereby secured so long as any such indebtedness shall be so
secured; provided, however, that nothing in this Section shall be construed to prevent Duke Holdco
from creating, or from suffering to be created or to exist, any mortgages, liens, pledges, security
interests or other encumbrances, or any agreements, with respect to:



     (1) purchase money mortgages, or other purchase money liens, pledges, security interests or
encumbrances of any kind upon property hereafter acquired by Duke Holdco, or mortgages, liens,
pledges, security interests or other encumbrances of any kind existing on any property at the time

encumbrances which exist on any property of a Person which is consolidated with or merged with or
into Duke Holdco or which transfers or leases all or substantially all of its properties to Duke
Holdco), or conditional sales agreements or other title retention agreements and leases in the
nature of title retention agreements with respect to any property hereafter acquired; provided,
however, that no such mortgage, lien, pledge, security interest or other encumbrance shall extend
to or cover any other property of Duke Holdco;

property of Duke Holdco existing as of the date of the Fifteenth Supplemental Indenture; liens for

or resulting from any litigation or proceeding which at the time is being contested in good faith
by appropriate proceedings; liens incurred in connection with the issuance of bankers’ acceptances

created in connection with, and created to secure, a non-recourse obligation; zoning restrictions,
easements, licenses, rights-of-way, restrictions on the use of property or minor irregularities in
title thereto, which do not, in the opinion of Duke Holdco, materially impair the use of such
property in the operation of the business of Duke Holdco or the value of such property for the
purpose of such business;



     (3) First and Refunding Mortgage Bonds of the Corporation issued or to be issued from time to
time under the First and Refunding Mortgage dated as of December 1, 1927 from the Corporation to

     (4) indebtedness which may be issued by Duke Holdco in connection with a consolidation or
merger of Duke Holdco with or into any other Person (which may be an Affiliate of Duke Holdco) in
exchange for or otherwise in substitution for secured indebtedness of such Persons (“Third Party
Debt”) which by its terms (i) is secured by a mortgage on all or a portion of the property of such
Person, (ii) prohibits secured indebtedness from being incurred by such Person, unless the Third
Party Debt shall be secured equally and ratably with such secured indebtedness or (iii) prohibits
secured indebtedness from being incurred by such Person;



     (5) indebtedness of any Person which is required to be assumed by Duke Holdco in connection
with a consolidation or merger of such Person, with respect to which any property of Duke Holdco is
subjected to a mortgage, lien, pledge, security interest or other encumbrance;

property acquired, constructed, developed, or improved by Duke Holdco (whether alone or in
association with others) after the date of this Fifteenth Supplemental Indenture which are created
prior to, at the time of, or within 18 months after such acquisition (or in the case of property
constructed, developed or improved, after the completion of such construction, development or
improvement and commencement of full commercial operation of such property, whichever is later) to
secure or provide for the payment of any part of the purchase price or cost thereof; provided that
in the case of such construction, development or improvement the mortgages, liens, pledges,
security interests or other encumbrances shall not apply to any property theretofore owned by Duke
Holdco other than theretofore unimproved real property;



     (7) Mortgages, liens, pledges, security interests or other encumbrances permitted to be
incurred by Duke Energy and Cinergy and their respective subsidiaries pursuant to their respective
debt instruments outstanding on the date hereof;



     (8) the replacement, extension or renewal (or successive replacements, extensions or
renewals), as a whole or in part, of any mortgage, lien, pledge, security interest or other

replacement, extension or renewal (not exceeding the principal amount of indebtedness secured
thereby together with any premium, interest, fee or expense payable in connection with any such
replacement, extension or renewal) of the indebtedness secured thereby; provided that such
replacement, extension or renewal is limited to all or a part of the same property that secured the
mortgage, lien, pledge, security interest or other encumbrance replaced, extended or renewed (plus
improvements thereon or additions or accessions thereto); or



     (9) any other mortgage, lien, pledge, security interest or other encumbrance not excepted by
the foregoing clauses (1) through (8); provided that immediately after the creation or assumption
of such mortgage, lien, pledge, security interest or other encumbrance, the aggregate principal
amount of



4









 







indebtedness for borrowed money of Duke Holdco secured by all mortgages, liens, pledges,
security interests and other encumbrances created or assumed under the provisions of this clause
(9) shall not exceed an amount equal to 10% of common stockholders’ equity of Duke Holdco as shown
on its consolidated balance sheet for the accounting period occurring immediately prior to the
creation or assumption of such mortgage, lien, pledge, security interest or other encumbrance.



     This Section 103 shall be for the sole benefit of the Notes and not for the benefit of any
future series of Securities Outstanding under the Indenture unless Duke Holdco agrees otherwise.



     Section 104. Duke Holdco May Consolidate, Etc., on Certain Terms. (1) Nothing
contained in the Indenture, this Fifteenth Supplemental Indenture or in any of the Notes shall
prevent any consolidation or merger of Duke Holdco with or into any other Person or Persons
(whether or not affiliated with Duke Holdco), or successive consolidations or mergers in which Duke
Holdco or its successor or successors shall be a party or parties, or shall prevent any conveyance
or transfer of the properties and assets of Duke Holdco as an entirety or substantially as an
entirety to any other Person (whether or not affiliated with Duke Holdco) lawfully entitled to
acquire the same; provided, however, and Duke Holdco hereby covenants and agrees, that upon any
such consolidation, merger, conveyance or transfer, (i) the obligations of Duke Holdco as set forth
in Section 102 herein shall be expressly assumed, by a supplemental indenture, in form reasonably
satisfactory to the Trustee, executed and delivered to the Trustee by the Person (if other than
Duke Holdco) formed by such consolidation, or into which Duke Holdco shall have been merged, or by
the Person which shall have acquired such properties and assets and (ii) Duke Holdco shall deliver
to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance or transfer and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture, comply with this Section and that
all conditions precedent herein provided for relating to such transaction have been complied with.



     Solely for the purpose of clause (ii) of this Section 104(1), the term “Corporation,”
appearing in the definition of the term “Officers’ Certificate” in Section 101 of the Original
Indenture, shall be changed to “Duke Holdco.”



     (2) Upon any consolidation of Duke Holdco with, or merger of Duke Holdco into, any other
Person or any conveyance or transfer of the properties and assets of Duke Holdco as an entirety or
substantially as an entirety in accordance with this Section, the successor Person formed by such
consolidation or into which Duke Holdco is merged or to which such conveyance or transfer is made
shall succeed to, and be substituted for, and may exercise every right and power of, Duke Holdco
under this Fifteenth Supplemental Indenture and the Indenture with the same effect as if such
successor Person had been named as Duke Holdco herein, and thereafter the predecessor Person shall
be relieved of all obligations and covenants under this Fifteenth Supplemental Indenture, the
Indenture and the Notes.



     This Section 104 shall be for the sole benefit of the Notes and not for the benefit of any
future series of Securities Outstanding under the Indenture unless Duke Holdco agrees otherwise.
