(b) If at any time when a prospectus relating to the Shares (or the notice referred to in Rule 173(a) of the 1933 Act Regulations) is required to be delivered under the 1933 Act any event occurs as a result of which the Pricing Disclosure Package or the Prospectus as then amended or supplemented would include an untrue statement of a material fact, or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Pricing Disclosure Package or the Prospectus to comply with the 1933 Act, the Corporation promptly will prepare and file with the Commission an amendment, supplement or an appropriate document pursuant to Section 13 or 14 of the 1934 Act which will correct such statement or omission or which will effect such compliance.

(e) The Corporation agrees that if at any time following the issuance of a Permitted Free Writing Prospectus or any electronic roadshow or other written communication that constitutes an offer to buy the Shares provided to investors by, or with the approval of, the Corporation, any event occurs as a result of which such Permitted Free Writing Prospectus or such electronic roadshow or other written communication would conflict with the information (not superseded or modified as of the Effective Date) in the Registration Statement, the Pricing Disclosure Package or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Corporation will give prompt notice thereof to the Underwriters and the Forward Seller and, if requested by the Underwriters and the Forward Seller, will prepare and furnish without charge to each Underwriter and the Forward Seller a free writing prospectus or other document, the use of which has been consented to by the Underwriters, which will correct such conflict, statement or omission.

8. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Underwritten Shares on the First Time of Delivery or the Option Shares on the Option Time of Delivery, and the obligations of the Forward Seller to deliver and sell the Borrowed Underwritten Shares on the First Time of Delivery or the Borrowed Option Shares on the Option Time of Delivery, as the case may be, are subject to the accuracy of the representations and warranties on the part of the Corporation herein, to the accuracy of the statements of officers of the Corporation made pursuant to the provisions hereof, to the performance by the Corporation of its obligations hereunder and to the following additional conditions precedent:

(e) The Representatives, the Forward Purchaser and the Forward Seller, shall have received an opinion of Robert T. Lucas III, Esq., Deputy General Counsel of Duke Energy Business Services, LLC, a service company subsidiary of the Corporation, dated such Time of Delivery, to the effect that:

(i) Each of the Principal Subsidiaries, other than each of Duke Energy Carolinas, LLC, Duke Energy Florida, LLC and Duke Energy Progress, LLC, has been duly incorporated and is validly existing in good standing under the laws of the jurisdiction of its incorporation and has the respective corporate power and authority and foreign qualifications necessary to own its properties and to conduct its business as described in the Pricing Disclosure Package and the Prospectus. Each of Duke Energy Carolinas, LLC, Duke Energy Florida, LLC and Duke Energy Progress, LLC, has been duly organized and is validly existing and in good standing as a limited liability company under the laws of the State of North Carolina, the State of Florida, and the State of North Carolina, respectively, and has full limited liability company power and authority necessary to own its properties and to conduct its business as described in the Pricing Disclosure Package and the Prospectus.

(ii) Each of the Corporation and the Principal Subsidiaries is duly qualified to do business in each jurisdiction in which the ownership or leasing of its property or the conduct of its business requires such qualification, except where the failure to so qualify, considering all such cases in the aggregate, does not have a material adverse effect on the business, properties, financial condition or results of operations of the Corporation and its subsidiaries taken as a whole.

(iii) The Registration Statement became effective upon filing with the Commission pursuant to Rule 462 of the 1933 Act Regulations, and, to the best of such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened under the 1933 Act.

(iv) The descriptions in the Registration Statement, the Pricing Disclosure Package and the Prospectus of any legal or governmental proceedings are accurate and fairly present the information required to be shown, and such counsel does not know of any litigation or any legal or governmental proceeding instituted or threatened against the Corporation or any of its Principal Subsidiaries or any

of their respective properties that would be required to be disclosed in the Registration Statement, the Pricing Disclosure Package or the Prospectus and is not so disclosed.

(v) This Agreement and the Forward Sale Agreement have been, and the Additional Forward Sale Agreement, if any, will be, duly authorized, executed and delivered by the Corporation.

(vi) The execution, delivery and performance by the Corporation of this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement and the consummation by the Corporation of the transactions contemplated hereby and thereby, including the issuance and sale of the Corporation Shares, if any, to be issued and sold by the Corporation hereunder, will not violate or contravene any of the provisions of the Certificate of Incorporation or By-Laws of the Corporation or any statute or any order, rule or regulation of which such counsel is aware of any court or governmental agency or body having jurisdiction over the Corporation or any of its Principal Subsidiaries or any of their respective property, nor will such action conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to such counsel to which the Corporation or any of its Principal Subsidiaries is a party or by which any of them or their respective property is bound or to which any of its property or assets is subject which affects in a material way the Corporation’s ability to perform its obligations under this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement.

(vii) No consent, approval, authorization, order, registration or qualification is required to authorize, or for the Corporation to consummate the transactions contemplated by this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement, except for such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Shares by the Underwriters, the Forward Seller and the Forward Purchaser and except as required in Condition 7.6 of the order of the North Carolina Utilities Commission dated June 29, 2012, in Docket No. E-7, sub 986, which consent has been obtained.

(viii) The North Carolina Utilities Commission has issued an appropriate order with respect to the issuance and sale of the Shares in accordance with this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement, and, to the best of such counsel’s knowledge, such orders are still in effect; the issuance and sale of the Shares to the Underwriters are in conformity with the terms of such orders; and no other authorization, approval or consent of any other governmental body (other than in connection or compliance with the provisions of the securities or Blue Sky laws of any jurisdiction) is legally required for the issuance and sale of the Shares

pursuant to this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement.

(ix) The Corporation Shares, if any, to be issued and sold by the Corporation hereunder have been duly authorized, and, upon payment and delivery in accordance with this Agreement, such Corporation Shares will be validly issued, fully paid and nonassessable; none of the Shares are subject to preemptive rights of any security holder of the Corporation; and the Shares conform as to legal matters in all material respects to the description thereof in (i) the Base Prospectus under the caption “Description of Capital Stock” and (ii) the Pricing Disclosure Package and the Prospectus under the caption “Description of Common Stock”. A number of shares of Common Stock equal to two times the aggregate Full Number of Shares (as such term is defined in the Forward Sale Agreement or the Additional Forward Sale Agreement, as applicable) have been duly authorized in connection with any share settlement obligations under the Forward Sale Agreement or Additional Forward Sale Agreement, if any (including in upon Physical Settlement or Net Share Settlement (as such terms are defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable)) and, upon issuance pursuant to the terms of the Transaction (as defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable), will be validly issued, fully paid and nonassessable (subject to customary exceptions, limitations and qualifications).

Such counsel shall state that nothing has come to his attention that has caused him to believe that each document incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus, when filed, was not, on its face, appropriately responsive, in all material respects, to the requirements of the 1934 Act and the 1934 Act Regulations. Such counsel shall also state that nothing has come to his attention that has caused him to believe that (i) the Registration Statement, including the Rule 430B Information, as of its effective date and at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) of the 1933 Act Regulations, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Pricing Disclosure Package at the Applicable Time contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) that the Prospectus or any amendment or supplement thereto, as of their respective dates and at such Time of Delivery, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Such counsel may also state that, except as otherwise expressly provided in such opinion, he does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in or incorporated by reference into the Registration Statement, the Pricing Disclosure Package or the Prospectus and does not express any opinion or belief as to (i) the financial statements or other financial and accounting data contained or incorporated by reference therein, including XBRL interactive data or (ii) the information in the Prospectus under the caption “Book-Entry System.”

In rendering the foregoing opinion, such counsel may state that he does not express any opinion concerning any law other than the law of the State of North Carolina or, to the extent set forth in the foregoing opinions, the federal securities laws and may rely as to all matters of the laws of the States of South Carolina, Ohio, Indiana and Florida on appropriate counsel reasonably satisfactory to the Representatives, which may include the Corporation’s other “in-house” counsel). Such counsel may also state that he has relied as to certain factual matters on information obtained from public officials, officers of the Corporation and other sources believed by him to be responsible.

(f) The Representatives, the Forward Purchaser and the Forward Seller, shall have received an opinion or opinions of Hunton & Williams LLP, counsel to the Corporation, dated such Time of Delivery, to the effect that:

(i) This Agreement and the Forward Sale Agreement have been, and each Additional Forward Sale Agreement will be, duly authorized, executed and delivered by the Corporation.

(ii) The Forward Sale Agreement is, and each Additional Forward Sale Agreement (if any) will be, valid and binding agreements of the Corporation, enforceable against the Corporation in accordance with their terms.

(iii) The execution and delivery by the Corporation of this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement and the consummation by the Corporation of the transactions contemplated hereby and thereby, including the issuance and sale of the Corporation Shares, if any, to be issued and sold by the Corporation hereunder, will not (i) conflict with the Corporation’s certificate of incorporation or Bylaws, (ii) constitute a violation of, or a breach of or default under, the terms of any of the contracts set forth on Schedule IV hereto or (iii) violate or conflict with, or result in any contravention of, any Applicable Law. “Applicable Law” means the General Corporation Law of the State of Delaware and those laws, rules and regulations of the States of New York and North Carolina and those federal laws, rules and regulations of the United States of America, in each case that, in such counsel’s experience, are normally applicable to transactions of the type contemplated by this Agreement (other than the United States federal securities laws, state securities or blue sky laws, antifraud laws and the rules and regulations of the Financial Industry Regulatory Authority, Inc., the North Carolina Public Utilities Act, the rules and regulations of the North Carolina Utilities Commission and the New York State Public Service Commission and the New York State Public Service Law), but without our having made any special investigation as to the applicability of any specific law, rule or regulation.

(iv) No Governmental Approval, which has not been obtained or taken and is not in full force and effect, is required to authorize, or is required for, the execution or delivery of this Agreement, the Forward Sale Agreement or any Additional Forward Sale Agreement by the Corporation or the consummation

by the Corporation of the transactions contemplated hereby or thereby, except for (A) registration of the Shares under the 1933 Act and (B) such consents, approvals, authorizations, orders, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Shares by the Underwriters. “Governmental Approval” means any consent, approval, license, authorization or validation of, or filing, qualification or registration with, any Governmental Authority required to be made or obtained by the Corporation pursuant to Applicable Laws, other than any consent, approval, license, authorization, validation, filing, qualification or registration that may have become applicable as a result of the involvement of any party (other than the Corporation) in the transactions contemplated by this Agreement, the Forward Sale Agreement or any Additional Forward Sale Agreement or because of such parties’ legal or regulatory status or because of any other facts specifically pertaining to such parties and “Governmental Authority” means any court, regulatory body, administrative agency or governmental body of the State of North Carolina, the State of New York or the State of Delaware or the United States of America having jurisdiction over the Corporation under Applicable Law but excluding the North Carolina Utilities Commission, the New York Public Service Commission and the Delaware Public Service Commission.

(v) The Corporation has been duly incorporated and is validly existing in good standing under the laws of the State of Delaware, and has the corporate power and corporate authority to execute and deliver this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement and to consummate the transactions contemplated hereby and thereby.

(vi) The Corporation Shares, if any, to be issued and sold by the Corporation hereunder have been duly authorized, and, upon payment and delivery in accordance with this Agreement, such Corporation Shares will be validly issued, fully paid and nonassessable; there are no preemptive rights under federal or New York law or under the General Corporation Law of the State of Delaware to subscribe for or to purchase Shares; there are no preemptive or other similar rights to subscribe for or to purchase Shares pursuant to the Certificate of Incorporation or By-Laws of the Corporation or any agreement or other instrument filed or incorporated by reference therein, or as an exhibit to, the Registration Statement. A number of shares of Common Stock equal to two times the aggregate Full Number of Shares (as such term is defined in the Forward Sale Agreement or the Additional Forward Sale Agreement, as applicable) have been duly authorized in connection with any share settlement obligations under the Forward Sale Agreement or Additional Forward Sale Agreement, if any (including in upon Physical Settlement or Net Share Settlement (as such terms are defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable)) and, upon issuance pursuant to the terms of the Transaction (as defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable), will be

validly issued, fully paid and nonassessable (subject to customary exceptions, limitations and qualifications).

(vii) The Corporation is not and, solely after giving effect to the offering and sale of the Shares and the application of the proceeds thereof as described in the Prospectus, will not be an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

(viii) The statements set forth in the Pricing Disclosure Package and the Prospectus under the caption “Underwriting,” insofar as such statements purport to summarize certain provisions of this Agreement, fairly summarize such provisions in all material respects.

(ix) The statements set forth (i) under the caption “Description of Capital Stock” in the Base Prospectus and (ii) under the caption “Description of Common Stock” in the Pricing Disclosure Package and the Prospectus, insofar as such statements purport to summarize the terms of the Shares, fairly summarize such terms in all material respects.

(x) The statements set forth in the Prospectus under the caption “U.S. Federal Income Tax Considerations for Non-U.S. Holders,” insofar as they purport to constitute summaries of matters of United States federal income tax law, constitute accurate and complete summaries, in all material respects, subject to the qualifications set forth therein.

The Representatives, the Forward Purchaser and the Forward Seller, shall also have received a statement of Hunton & Williams LLP, dated such Time of Delivery, to the effect that:

(i) no facts have come to such counsel’s attention that have caused such counsel to believe that the documents filed by the Corporation under the 1934 Act and the 1934 Act Regulations that are incorporated by reference in the Preliminary Prospectus Supplement that forms a part of the Pricing Disclosure Package and the Prospectus, when filed, were not, on their face, appropriately responsive in all material respects to the requirements of the 1934 Act and the 1934 Act Regulations (except that in each case such counsel need not express any view as to the financial statements, schedules and other financial and accounting information included or incorporated by reference therein or excluded therefrom or compliance with XBRL interactive data requirements) (ii) the Registration Statement, at the Applicable Time and the Prospectus, as of its date, appeared on their face to be appropriately responsive in all material respects to the requirements of the 1933 Act and the 1933 Act Regulations (except that in each case such counsel need not express any view as to the financial statements, schedules and other financial and accounting information included or incorporated by reference therein or excluded therefrom or compliance with XBRL interactive data requirements) and (iii) no facts have come to such counsel’s attention that have caused such counsel to believe that the Registration Statement, at the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as of its date and as of such Time of Delivery, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which

they were made, not misleading (except that in each case such counsel need not express any view as to the financial statements, schedules and other financial and accounting information included or incorporated by reference therein or excluded therefrom, including XBRL interactive data, or the statements contained in the exhibits to the Registration Statement). Such counsel shall further state that, in addition, no facts have come to such counsel’s attention that have caused such counsel to believe that the Pricing Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that such counsel need not express any view as to the financial statements, schedules and other financial and accounting information included or incorporated by reference therein or excluded therefrom, including XBRL interactive data, or the statements contained in the exhibits to the Registration Statement).

In addition, such statement shall confirm that the Prospectus has been filed with the Commission within the time period required by Rule 424 of the 1933 Act Regulations and any required filing of a Permitted Free Writing Prospectus pursuant to Rule 433 of the 1933 Act Regulations has been filed with the Commission within the time period required by Rule 433(d) of the 1933 Act Regulations. Such statement shall further state that, assuming the accuracy of the representations and warranties of the Corporation set forth in Section 2 hereof, the Registration Statement became effective upon filing with the Commission pursuant to Rule 462 of the 1933 Act Regulations, and that based solely on such counsel’s review of the Commission’s website, no stop order suspending the effectiveness of the Registration Statement has been issued and, to such counsel’s knowledge, no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

Hunton & Williams LLP may state that they have relied as to certain factual matters on information obtained from public officials, officers and representatives of the Corporation and that the signatures on all documents examined by them are genuine, assumptions which such counsel have not independently verified.

(g) The Representatives, the Forward Purchaser and the Forward Seller, shall have received an opinion of Sidley Austin LLP, counsel for the Underwriters, the Forward Purchaser and the Forward Seller, dated such Time of Delivery, with respect to the validity of the Shares, the Registration Statement, the Pricing Disclosure Package and the Prospectus, as amended or supplemented, and such other related matters as you may require, and the Corporation shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

Delivery on the terms and in the manner contemplated in the Pricing Disclosure Package and the Prospectus. In such event there shall be no liability on the part of any party to any other party except as otherwise provided in Section 9 hereof and except for the expenses to be borne by the Corporation as provided in Section 7(i) hereof.

9. Indemnification. (a) The Corporation agrees to indemnify and hold harmless each Underwriter, the Forward Purchaser and the Forward Seller, their respective affiliates, officers and directors, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) including the Rule 430B Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus (or any amendment or supplement thereto), any Permitted Free Writing Prospectus, any issuer free writing prospectus as defined in Rule 433 of the 1933 Act Regulations or any electronic roadshow or other written communication that constitutes an offer to buy the Shares provided to investors by, or with the approval of, the Corporation, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, unless such statement or omission or such alleged statement or omission was made in reliance upon and in conformity with written information furnished to the Corporation by the Representatives on behalf of the Underwriters or the Forward Purchaser or Forward Seller expressly for use in the Registration Statement (or any amendment thereto), the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus (or any amendment or supplement thereto) or any Permitted Free Writing Prospectus;

(ii) against any and all loss, liability, claim, damage and expense whatsoever to the extent of the aggregate amount paid in settlement of any litigation, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Corporation; and

(iii) against any and all expense whatsoever reasonably incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) of this Section 9.

In no case shall the Corporation be liable under this indemnity agreement with respect to any claim made against any Underwriter or any such controlling person unless the Corporation shall be notified in writing of the nature of the claim within a reasonable time after the assertion thereof, but failure so to notify the Corporation shall not relieve it from any liability which it may have otherwise than under subsections 9(a) and 9(b). The Corporation shall be entitled to participate at its own expense in the defense, or, if it so elects, within a reasonable time after receipt of such notice, to assume the defense of any suit brought to enforce any such claim, but if it so elects to assume the defense, such defense shall be conducted by counsel chosen by it and approved by the Underwriter or Underwriters or controlling person or persons, or defendant or defendants in any suit so brought, which approval shall not be unreasonably withheld. In any such suit, any Underwriter or any such controlling person shall have the right to employ its own counsel, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless (i) the Corporation and such Underwriter shall have mutually agreed to the employment of such counsel, or (ii) the named parties to any such action (including any impleaded parties) include both such Underwriter or such controlling person and the Corporation and such Underwriter or such controlling person shall have been advised by such counsel that a conflict of interest between the Corporation and such Underwriter or such controlling person may arise and for this reason it is not desirable for the same counsel to represent both the indemnifying party and also the indemnified party (it being understood, however, that the Corporation shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for all such Underwriters and all such controlling persons, which firm shall be designated in writing by you). The Corporation agrees to notify you within a reasonable time of the assertion of any claim against it, any of its officers or directors or any person who controls the Corporation within the meaning of Section 15 of the 1933 Act, in connection with the sale of the Shares.

(b) (i) Each Underwriter, severally and not jointly, agrees that it will indemnify and hold harmless the Corporation, its directors and each of the officers of the Corporation who signed the Registration Statement and each person, if any, who controls the Corporation within the meaning of Section 15 of the 1933 Act to the same extent as the indemnity contained in subsection (a) of this Section, but only with respect to statements or omissions made in the Registration Statement (or any amendment thereto), the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus (or any amendment or supplement thereto) or any Permitted Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Corporation by the Representatives on behalf of the Underwriters expressly for use in the Registration Statement (or any amendment thereto), the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus (or

any amendment or supplement thereto) or any Permitted Free Writing Prospectus. In case any action shall be brought against the Corporation or any person so indemnified based on the Registration Statement (or any amendment thereto), the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus (or any amendment or supplement thereto) or any Permitted Free Writing Prospectus and in respect of which indemnity may be sought against any Underwriter, such Underwriter shall have the rights and duties given to the Corporation, and the Corporation and each person so indemnified shall have the rights and duties given to the Underwriters by the provisions of subsection (a) of this Section.

(ii) The Forward Seller agrees that it will indemnify and hold harmless the Corporation, its directors and each of the officers who signed the Registration Statement, each Underwriter, each of the directors and officers of each Underwriter, and each person, if any, who controls the Corporation or any of the Underwriters within the meaning of Section 15 of the 1933 Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any and all loss, liability, claim, damage and expense whatsoever arising out of, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any written information relating to the Forward Seller or the Forward Purchaser furnished to the Corporation by the Forward Seller or the Forward Purchaser expressly for use in the Registration Statement, the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus (or any amendment or supplement thereto), any Permitted Free Writing Prospectus and any issuer free writing prospectus as defined in Rule 433 of the 1933 Act Regulations, it being understood and agreed upon that the only such information furnished by the Forward Seller or the Forward Purchaser consists of the following information in the Prospectus: the statement regarding affiliations with Barclays Capital Inc. on the cover page of the Prospectus.

(c) No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party in respect of any and all loss, liability, claim, damage and expense whatsoever (or actions in respect thereof) that would otherwise have been indemnified under the terms of such indemnity, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the

Corporation on the one hand and the Underwriters, the Forward Purchaser and the Forward Seller on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Corporation on the one hand and the Underwriters, the Forward Purchaser and the Forward Seller on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Corporation on the one hand and the Underwriters, the Forward Purchaser and the Forward Seller on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Corporation (which benefits shall include the proceeds to be received by the Corporation pursuant to the Forward Sale Agreement and the Additional Forward Sale Agreement, if any, assuming, in each case, Physical Settlement thereof on the Effective Date (as such terms are defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as the case may be)) bear to the total compensation received by the Underwriters in respect of the underwriting discount as set forth in the table on the cover page of the Prospectus, or with respect to the Forward Seller and the Forward Purchaser, the aggregate spread received by affiliates of the Forward Seller under the Forward Sale Agreement and the Additional Forward Sale Agreement, if any, net of any costs associated therewith, as reasonably determined by the Forward Seller, bear to the aggregate offering price, as applicable. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Corporation on the one hand or the Underwriters, the Forward Purchaser or the Forward Seller on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Corporation, the Underwriters and the Forward Seller agree that it would not be just and equitable if contributions pursuant to this Section were determined by pro rata allocation (even if the Underwriters, the Forward Purchaser and the Forward Seller were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section. The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to above in this Section shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section, no Underwriter, Forward Purchaser or Forward Seller (except as may be provided in any agreement among the Underwriters, the Forward Purchaser and the Forward Seller relating to the offering of the Shares) shall be required to contribute any amount in excess of the amount, with respect to the Underwriters, by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public or, with respect to the Forward Seller and the Forward Purchaser, the aggregate spread

received by affiliates of the Forward Seller under the Forward Sale Agreement and the Additional Forward Sale Agreement, if any, net of any costs associated therewith, exceeds the amount of any damages which such Underwriter, Forward Purchaser or Forward Seller has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ and the Forward Seller’s obligations to contribute are several in proportion to their respective obligations and not joint.

10. Default by One or More of the Underwriters.

(a) If any Underwriter shall default in its obligation to purchase the number of Shares which it has agreed to purchase hereunder on such Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Corporation shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Corporation that you have so arranged for the purchase of such Shares, or the Corporation notifies you that it has so arranged for the purchase of such Shares, you or the Corporation shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement, the Pricing Disclosure Package or the Prospectus, or in any other documents or arrangements, and the Corporation agrees to file promptly any amendments to the Registration Statement, the Pricing Disclosure Package or the Prospectus which may be required. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you or the Corporation as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-tenth of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Corporation shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you or the Corporation as provided in subsection (a) above, the aggregate number of such Shares which remains

unpurchased exceeds one-tenth of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Corporation shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Option Time of Delivery, if any, the obligations of the Underwriters to purchase and of the Corporation to sell the Option Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Corporation, except for the expenses to be borne by the Corporation as provided in Section 7(i) hereof and the indemnity and contribution agreement in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. Issuance and Sale by the Corporation.

(a) In the event that (i) all the Conditions are not satisfied on or prior to the First Time of Delivery or, in respect of the Additional Forward Sale Agreement, if any, entered into pursuant to Section 4(b), all the Additional Conditions are not satisfied on the Option Time of Delivery, if any, as the case may be, and the Forward Seller elects, pursuant to Section 4(c) or Section 4(d) hereof, as the case may be, not to deliver the Borrowed Underwritten Shares or the Borrowed Option Shares deliverable by the Forward Seller, as applicable, (ii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller is unable to borrow and deliver for sale under this Agreement a number of shares of Common Stock equal to the number of the Borrowed Underwritten Shares or Borrowed Option Shares, as applicable, to be borrowed and delivered for sale by the Forward Seller under this Agreement or (iii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller would incur a stock loan cost of more than a rate equal to 50 basis points per annum to do so, then, in each case, the Corporation shall issue and sell to the Underwriters, pursuant to Section 4 hereof, in whole but not in part, an aggregate number of shares of Common Stock equal to the number of Borrowed Underwritten Shares or Borrowed Option Shares, as the case may be, that the Forward Seller does not so deliver and sell to the Underwriters. In connection with any such issuance and sale by the Corporation, the Corporation or the Representatives shall have the right to postpone the First Time of Delivery or the Option Time of Delivery, as the case may be, for a period not exceeding three business days in order to effect any required changes in any documents or arrangements. The shares of Common Stock sold by the Corporation to the Underwriters pursuant to this Section 11(a) in lieu of Borrowed Underwritten Shares are referred to herein as the “Corporation Top-Up Underwritten Shares,” and the shares of Common Stock sold by the Corporation to the Underwriters pursuant to this Section 11(a) in lieu of Borrowed Option Shares are referred to herein as the “Corporation Top-Up Option Shares.”

(b) Neither the Forward Purchaser nor the Forward Seller shall have any liability whatsoever for any Borrowed Shares that the Forward Seller does not deliver and sell to the Underwriters or any other party if (i) all of the Conditions are not satisfied on or prior to the First Time of Delivery, in the case of Borrowed Underwritten Shares, or all of the Additional Conditions are not satisfied on or prior to the Option Time of Delivery, in the case of Borrowed Option Shares, and the Forward Seller elects,

pursuant to Section 4(c) or Section 4(d) hereof, as the case may be, not to deliver and sell to the Underwriters the Borrowed Underwritten Shares or the Borrowed Option Shares, as applicable, (ii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller is unable to borrow and deliver for sale under this Agreement on the First Time of Delivery or the Option Time of Delivery, as the case may be, a number of shares of Common Stock equal to the number of the Borrowed Underwritten Shares or Borrowed Option Shares, as applicable, to be borrowed and delivered for sale by the Forward Seller under this Agreement or (iii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller would incur a stock loan cost of more than a rate equal to 50 basis points per annum to do so.

12. Survival. The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the Corporation or its officers and of the several Underwriters and the Forward Seller set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Forward Purchaser and the Forward Seller or the Corporation, or any of its officers or directors or any controlling person, and shall survive delivery of and payment for the Shares.

13. Reliance on Your Acts. In all dealings hereunder, the Representatives shall act on behalf of each of the Underwriters, and the Corporation shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives.

14. No Fiduciary Relationship. The Corporation acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Corporation on the one hand, and the Underwriters, the Forward Purchaser and the Forward Seller on the other hand, (ii) in connection with the offering contemplated hereby and the process leading to such transaction, each Underwriter, Forward Purchaser and Forward Seller is and has been acting solely as a principal and is not the agent or fiduciary of the Corporation or its shareholders, creditors, employees, or any other party, (iii) no Underwriter, Forward Purchaser or Forward Seller has assumed or will assume an advisory or fiduciary responsibility in favor of the Corporation with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter, Forward Purchaser or Forward Seller has advised or is currently advising the Corporation on other matters) and no Underwriter, Forward Purchaser or Forward Seller has any obligation to the Corporation with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, the Forward Sale Agreement and the Additional Forward Sale Agreement, if any, (iv) the Underwriters, the Forward Purchaser and the Forward Seller and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Corporation, and (v) the Underwriters, the Forward Purchaser and the Forward Seller have not provided any legal, accounting, regulatory or tax advice with respect to the transaction contemplated hereby and the Corporation has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SUBJECT:		Additional Issuer Forward Transaction

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the Transaction entered into between Barclays Bank PLC (“Barclays”), through its agent Barclays Capital Inc. (the “Agent”), and Duke Energy Corporation (“Counterparty”), on the Trade Date specified below (the “Transaction”). This Confirmation constitutes a “Confirmation” as referred to in the Agreement specified below. This Confirmation is a confirmation for purposes of Rule 10b-10 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

This Confirmation evidences a complete and binding agreement between Barclays and Counterparty as to the terms of the Transaction to which this Confirmation relates and supersedes all prior or contemporaneous written or oral communications with respect thereto. This Confirmation shall supplement, form a part of, and be subject to an agreement (the “Agreement”) in the form of the 1992 ISDA Master Agreement (Multicurrency — Cross Border) as if Barclays and Counterparty had executed an agreement in such form (without any Schedule but with the elections set forth in this Confirmation) on the Trade Date. The Transaction hereunder shall be the sole Transaction under the Agreement. If there exists any ISDA Master Agreement between Barclays and Counterparty or any confirmation or other agreement between Barclays and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Barclays and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which Barclays and Counterparty are parties, the Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

The definitions and provisions contained in the 2006 ISDA Definitions (the “Swap Definitions”) and the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”) as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. Any reference to a currency shall have the meaning contained in Section 1.7 of the 2006 ISDA Definitions as published by ISDA.

NOTWITHSTANDING THE FOREGOING, OR ANYTHING TO THE CONTRARY IN THIS CONFIRMATION OR THE AGREEMENT, COUNTERPARTY DOES NOT BY THIS CONFIRMATION OR

THE TRANSACTION HEREUNDER SUBMIT TO THE JURISDICTION OF ANY FOREIGN NATION OR FOREIGN SUPRANATIONAL ORGANIZATION OR SUCH ENTITY’S LAWS OR REGULATIONS, INCLUDING WITHOUT LIMITATION THE EUROPEAN MARKET INFRASTRUCTURE REGULATION. THIS CONFIRMATION, THE AGREEMENT AND THE TRANSACTION ARE INTENDED TO BE GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK AND NOT THE LAWS, RULES OR REGULATIONS OF ANY FOREIGN JURISDICTION.

THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES DISTRICT COURT LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK CITY IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS.

The portion of the Undesignated Shares designated for valuation and settlement in respect of a Designated Date shall be the “Designated Shares” for such Designated Date. If the number of Undesignated Shares on the Maturity Date is greater than zero, then the Maturity Date will be a Designated Date for a Physical Settlement with a number of Designated Shares equal to such number of Undesignated Shares.

		trading on any Exchange Business Day is scheduled following the date hereof, then such Exchange Business Day shall be deemed to be a Disrupted Day in full.

		A “Regulatory Disruption” shall occur if Barclays determines in good faith and in its reasonable discretion, based on advice of counsel, that it is appropriate in light of legal, regulatory or self-regulatory requirements or related policies or procedures (so long as such requirements, policies or procedures, if voluntarily adopted by Barclays, generally are applicable in similar circumstances and are not arbitrarily or capriciously applied) for Barclays (or its agent or affiliate) to refrain from all or any part of the market activity in which it would otherwise engage in connection with the Transaction.

(a) Counterparty shall promptly provide written notice to Barclays upon obtaining knowledge of (i) the occurrence or announcement of any event that would constitute an Event of Default as to which it is the Defaulting Party or a Potential Adjustment Event or (ii) any Announcement Date in respect of an Extraordinary Event; provided that should Counterparty be in possession of material non-public information regarding Counterparty, Counterparty shall not communicate such information to Barclays;

(b) A number of Shares of Counterparty equal to [•](1) Shares, as such number may be reduced by a number of Shares issued directly by Counterparty as contemplated in the Underwriting Agreement (the “Capped Number”); has been reserved for issuance upon settlement of the Transaction by all required corporate action of Counterparty.

(1) Two times the Number of Shares or, if less, 19.9% of outstanding Shares * Number of Shares under this Confirmation / (aggregate Number of Shares for base and additional confirmation).

Without limiting the generality of the foregoing, during any Unwind Period, except with the prior written consent of Barclays, Counterparty will not, and will cause its affiliated purchasers (as defined in Rule 10b-18) not to, directly or indirectly (including, without limitation, by means of a derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or announce or commence any tender offer relating to, any Shares (or equivalent interest, including a unit of beneficial interest in a trust or limited partnership or a depository share) or any security convertible into or exchangeable for the Shares.

(b) If the Early Valuation Date occurs on a date that is not during an Unwind Period, then the Early Valuation Date shall be deemed to be a Designated Date for a Physical Settlement, and the number of Designated Shares for such Designated Date shall be the number of Undesignated Shares on the Early Valuation Date; provided that in the case of an Acceleration Event of the type described in paragraph (e)(iv) below, the number of Designated Shares for such Designated Date shall be only such number of Designated Shares necessary so that such Acceleration Event shall no longer exist after such Physical Settlement, as determined by the Calculation Agent; and, provided, further, that in the case of an Acceleration Event of the type described in paragraph (e)(i) below and resulting from the commencement of any proceeding with respect to Counterparty under the Bankruptcy Code other than in a Bankruptcy Termination Event, the Early Valuation Date shall be deemed to be the last Unwind Date for a Cash Settlement and in such case the aggregate net loss or cost reasonably determined by Barclays as of the related Early Valuation Date in connection with unwinding its Hedge Positions shall be added to the Forward Cash Settlement Amount (or, if an aggregate net gain is so determined, such gain shall be subtracted therefrom).

(c) If the Early Valuation Date occurs during an Unwind Period, then (i) (A) the last Unwind Date of such Unwind Period shall occur on the Early Valuation Date, (B) a settlement shall occur in respect of such Unwind Period, and the settlement method elected by Counterparty in respect of such settlement shall

apply, and (C) the number of Designated Shares for such settlement shall be deemed to be the number of Unwound Shares for such Unwind Period on the Early Valuation Date, and (ii) (A) the Early Valuation Date shall be deemed to be an additional Designated Date for a Physical Settlement and (B) the number of Designated Shares for such additional Designated Date shall be the Remaining Amount on the Early Valuation Date; provided that in the case of an Acceleration Event of the type described in paragraph (e)(iv) below, the number of Designated Shares for such additional Designated Date shall be only such number of Designated Shares necessary so that such Acceleration Event shall no longer exist after such Physical Settlement, as determined by the Calculation Agent; and, provided, further, that in the case of an Acceleration Event of the type described in paragraph (e)(i) below and resulting from the commencement of any proceeding with respect to Counterparty under the Bankruptcy Code other than in a Bankruptcy Termination Event, the Early Valuation Date shall be deemed to be the last Unwind Date of an additional Unwind Period for a Cash Settlement and the number of Designated Shares for such settlement shall be deemed to be the Remaining Amount on the Early Valuation Date and in such case the aggregate net loss or cost reasonably determined by Barclays as of the related Early Valuation Date in connection with unwinding its Hedge Positions shall be added to the Forward Cash Settlement Amount (or, if an aggregate net gain is so determined, such gain shall be subtracted therefrom).

(d) Notwithstanding the foregoing, in the case of an Early Valuation Date that occurs due to an announcement of a Nationalization or a Merger Event, if at the time of the related Settlement Date or Net Share Settlement Date, as applicable, the Shares have changed into cash or any other property or the right to receive cash or any other property, such cash, other property or right shall be deliverable instead of such Shares.

(e) “Acceleration Event” means:

(i) any Event of Default or Termination Event, other than an Event of Default or Termination Event that also constitutes a Bankruptcy Termination Event, that would give rise to the right of either party to designate an Early Termination Date pursuant to Section 6 of the Agreement;

(ii) the announcement of any event or transaction that, if consummated, would result in a Merger Event, Tender Offer, Nationalization, Delisting or Change in Law, in each case, as determined by the Calculation Agent;

(iii) (x) A Loss of Stock Borrow or Hedging Disruption or (y) (A) an Increased Cost of Stock Borrow or (B) an Increased Cost of Hedging, in the case of sub-clause (A) or (B), in connection with which Counterparty does not elect, and so notify the Hedging Party of its election, in each case, within the required time period to either amend the Transaction pursuant to Section 12.9(b)(v)(A) or Section 12.9(b)(vi)(A) of the Equity Definitions, as applicable, or pay an amount determined by the Calculation Agent that corresponds to the relevant Price Adjustment pursuant to Section 12.9(b)(v)(B) or Section 12.9(b)(vi)(B) of the Equity Definitions, as applicable;

(iv) the declaration or payment by Counterparty of any Extraordinary Dividend;

(v) the occurrence of a Market Disruption Event during an Unwind Period and the continuance of such Market Disruption Event for at least eight Scheduled Trading Days;

(vi) the occurrence of an Excess Section 13 Ownership Position or Excess Regulatory Ownership Position; or

(vii) the occurrence of the Maturity Date during an Unwind Period.

10. Private Placement Procedures: If either Barclays or Counterparty determines in good faith that Counterparty will be unable to comply with the covenant set forth in the second sentence of Section 6 of this Confirmation because of a change in law or a change in the policy of the Securities and Exchange Commission (“SEC”) or its staff (the “Staff”), or Barclays otherwise determines that in its reasonable opinion (based on the advice of counsel) any Shares to be delivered to Barclays by Counterparty hereunder may not be freely returned by Barclays or its affiliates to securities lenders as contemplated by Section 6 of this Confirmation (in either case without regard to exceptions therein), then delivery of any such Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Barclays.

11. Rule 10b5-1; Share Purchases by Barclays

(a) The parties acknowledge that, following any election of Cash Settlement or Net Share Settlement by Counterparty, this Confirmation is intended to constitute a binding contract satisfying the requirements of Rule 10b5-1(c) of the Exchange Act and agree that this Confirmation shall be interpreted to comply with such requirements.

(b) The times and prices at which Barclays (or its agent or affiliate) purchases any Shares during any Unwind Period shall be at Barclays’ good faith and commercially reasonable discretion. Counterparty acknowledges that during any Unwind Period Counterparty does not have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares or any other transactions by Barclays (or its agent or affiliate) in connection with this Confirmation. Counterparty agrees that during any Unwind Period it will not enter into or alter any corresponding or hedging transaction or position with respect to the Shares.

(c) Counterparty hereby agrees with Barclays that during any Unwind Period Counterparty shall not communicate, directly or indirectly, any material non-public information (within the meaning of such term under Rule 10b5-1) to any employee of Barclays (or its agents or affiliates) who is directly involved with the hedging of, and trading with respect to, the Transaction. Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of the Transaction must be effected in accordance with the requirements for the amendment or termination of a contract, instruction or plan under Rule 10b5-1(c). Without limiting the generality of the foregoing, any such amendment, modification, waiver or termination shall be made in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5 under the Exchange Act, and no such amendment, modification or waiver shall be made at any time at which Counterparty or any officer, director, manager or similar person of Counterparty is aware of any material non-public information regarding Counterparty or the Shares.

(d) Following any election of Cash Settlement or Net Share Settlement by Counterparty, in addition to the representations, warranties and covenants in the Agreement and elsewhere in this Confirmation, Barclays represents, warrants and covenants to Counterparty that Barclays shall use commercially reasonable efforts, during any Unwind Period, to make all purchases of Shares in connection with such election in a manner that would comply with the limitations set forth in clauses (b)(1), (b)(2), (b)(3) and (b)(4) and (c) of Rule 10b-18, as if such rule were applicable to such purchases (and considering only such purchases when determining compliance with the foregoing provisions), after taking into account any applicable SEC no-action letters as appropriate, subject to any delays between the execution and reporting of a trade of the Shares on the Exchange and other circumstances beyond Barclays’ control; provided that, during any Unwind Period, the foregoing agreement shall not apply to purchases made to dynamically hedge for Barclays’ own account or the account of its affiliate(s) the optionality arising under in connection with such Settlement (including, for the avoidance of doubt, timing optionality); and provided, further, that, without limiting the generality of the first sentence of this paragraph (d), Barclays shall not be responsible for any failure to comply with Rule 10b-18(b)(3) to the extent any transaction that was executed (or deemed to be executed) by or on behalf of Counterparty or an “affiliated purchaser” (as defined under Rule 10b-18) pursuant to a separate agreement is not deemed to be an “independent bid” or an “independent transaction” for purposes of Rule 10b-18(b)(3).

12. Capped Number of Shares: Notwithstanding any other provision of the Agreement or this Confirmation, in no event will Counterparty be required to deliver in the aggregate in respect of all Settlement Dates, Net Share Settlement Dates or other dates on which Shares are delivered in respect of any amount owed under this Confirmation a number of Shares greater than the Capped Number. Counterparty represents and warrants to Barclays (which representation and warranty shall be deemed to be repeated on each day that the Transaction is outstanding) that the Capped Number is equal to or less than the number of authorized but unissued Shares that are not reserved for future issuance in connection with transactions in the Shares (other than the Transaction) on the date of the determination of the Capped Number (such Shares, the “Available Shares”). In the event Counterparty shall not have delivered the full number of Shares otherwise deliverable as a result of this Section 12 (the resulting deficit, the “Deficit Shares”), Counterparty shall be continually obligated to deliver Shares, from time to time until the full number of Deficit Shares have been delivered pursuant to this paragraph, when, and to the extent, that (A) Shares are repurchased, acquired or otherwise received by Counterparty or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (B) authorized and unissued Shares reserved for issuance in respect of other transactions as of the Trade Date become no longer so reserved and (C) Counterparty authorizes any additional unissued Shares that are not reserved for other transactions (such events as set forth in clauses (A), (B) and (C) above, collectively, the “Share Issuance Events”). Counterparty shall promptly notify Barclays of the occurrence of any of the Share Issuance Events (including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares to be delivered) and, as promptly as reasonably practicable after such Share Issuance Event (or, if later, on the Settlement Date or the date of any Private Placement Settlement for which there are Deficit Shares), deliver such Shares. Counterparty shall not, until Counterparty’s obligations under the Transaction have been satisfied in full, use any Shares that become available for potential delivery to Barclays as a result of any Share Issuance Event for the settlement or satisfaction of any transaction or obligation other than the Transaction or the “Transaction” under the Base Confirmation or reserve any such Shares for future issuance for any purpose other than to satisfy Counterparty’s obligations to Barclays under the Transaction or the “Transaction” under the Base Confirmation.](2)

13. Transfer, Assignment and Designation:

(a) Notwithstanding any provision of the Agreement to the contrary, Barclays may assign, transfer and set over all rights, title and interest, powers, privileges and remedies of Barclays under the Transaction, in whole or part, to an affiliate of Barclays without the consent of Counterparty; provided that (i) no Event of Default, Potential Event of Default or Termination Event with respect to which Barclays or such affiliate is the Defaulting Party or an Affected Party, as the case may be, exists or would result therefrom, (ii) no Acceleration Event or other event giving rise to a right or responsibility to designate an Early Valuation Date or otherwise terminate or cancel the Transaction or to make an adjustment to the terms of the Transaction would result therefrom, and (iii) Counterparty shall not, as a result of such assignment or transfer, (A) be required to pay to Barclays or such affiliate an additional amount in respect of an Indemnifiable Tax, (B) receive a payment from which an amount is required to be deducted or withheld for or on account of a Tax as to which no additional amount is required to be paid, or (C) become subject to the jurisdiction of any state or country other than the United States of America.

(2) To be deleted if the Capped Number is based on 19.9% of TSO.

(b) Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Barclays to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Barclays may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Barclays’s obligations in respect of the Transaction and any such designee may assume such obligations. Barclays shall be discharged of its obligations to Counterparty to the extent of any such performance.

14. Indemnity: Counterparty agrees to indemnify Barclays and its affiliates and their respective directors, officers, agents and controlling parties (Barclays and each such affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, incurred by or asserted against such Indemnified Party, that arise out of, are in connection with, or relate to, the execution or delivery of this Confirmation by Counterparty, the performance by Counterparty of its obligations under the Transaction or any breach of any covenant or representation made by Counterparty in this Confirmation or the Agreement, and Counterparty will reimburse any Indemnified Party for all reasonable expenses (including reasonable legal fees and expenses) in connection with the investigation of, preparation for, or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto. Counterparty will not be liable under this Indemnity paragraph to the extent that any such loss, claim, damage, liability or expense resulted from an Indemnified Party’s gross negligence, bad faith or willful misconduct or Barclays’ breach of this Confirmation or the Agreement. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability not resulting from its gross negligence, bad faith or willful misconduct, provided that no person guilty of fraudulent misrepresentation shall be entitled to contribution.

15. No Collateral; Netting; Setoff:

(a) Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Counterparty hereunder are not secured by any collateral.

(b) If on any date any Shares would otherwise be deliverable under the Transaction or the Base Confirmation by Counterparty to Barclays and by Barclays to Counterparty, then, on such date, each party’s obligations to make delivery of such Shares will be automatically satisfied and discharged and, if the aggregate number of Shares that would otherwise have been deliverable by one party exceeds the aggregate number of Shares that would have otherwise been deliverable by the other party, replaced by an obligation upon the party by whom the larger aggregate number of Shares would have been deliverable to deliver to the other party the excess of the larger aggregate number over the smaller aggregate number.

(c) The parties agree that upon the occurrence of an Event of Default or Termination Event with respect to a party who is the Defaulting Party or the Affected Party (“X”), the other party (“Y”) will have the right (but not be obliged) without prior notice to X or any other person to set-off or apply any obligation of X owed to Y (or any affiliate of Y) (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation) against any obligation of Y (or any affiliate of Y) owed to X (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of

the obligation). Y will give notice to the other party of any set-off effected under this Section 15.

(d) Amounts (or the relevant portion of such amounts) subject to set-off may be converted by Y into the Termination Currency or into Shares, at the election of Y, at the rate of exchange at which such party would be able, acting in a reasonable manner and in good faith, to purchase the relevant amount of such currency or Shares. If any obligation is unascertained, Y may in good faith estimate that obligation and set-off in respect of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained. Nothing in this Section 15 shall be effective to create a charge or other security interest. This Section 15 shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).

(e) Notwithstanding anything to the contrary in the foregoing, Barclays agrees not to set off or net amounts due from Counterparty with respect to the Transaction against amounts due from Barclays (or its affiliate) to Counterparty with respect to contracts or instruments that are not Equity Contracts; provided, however, that, and notwithstanding any provision to the contrary set forth in this Confirmation or in the Agreement, Barclays may not use this provision or any other set-off or recoupment right under this Confirmation or the Agreement as a basis for any action under or nonperformance of its obligations under any loan, letter of credit or other borrowing arrangement with Counterparty as borrower and to which Barclays or any affiliate of Barclays is a participating lender, with respect to which the terms of such loan, letter of credit or other borrowing arrangement shall control. “Equity Contract” means any transaction or instrument that does not convey to Barclays rights, or the ability to assert claims, that are senior to the rights and claims of common stockholders in the event of Counterparty’s bankruptcy.

16. Delivery of Cash: For the avoidance of doubt, nothing in this Confirmation shall be interpreted as requiring Counterparty to deliver cash in respect of the settlement of the Transaction, except (i) as set forth under Section 8 above or (ii) in circumstances where the cash settlement thereof is within Counterparty’s control (including, without limitation, where Counterparty so elects to deliver cash or fails timely to deliver Shares in respect of such settlement). For the avoidance of doubt, the preceding sentence shall not be construed as limiting any damages that may be payable by Counterparty as a result of a breach of or an indemnity under this Confirmation or the Agreement.

17. Status of Claims in Bankruptcy: Barclays acknowledges and agrees that this Confirmation is not intended to convey to Barclays rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Barclays’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to this Confirmation and the Agreement; and provided further that nothing herein shall limit or shall be deemed to limit Barclays’s rights in respect of any transaction other than the Transaction.

18. Limit on Beneficial Ownership: Notwithstanding anything to the contrary in the Agreement or this Confirmation, in no event shall Barclays be entitled to receive, or be deemed to receive, Shares to the extent that, upon such receipt of such Shares, and after taking into account any Shares concurrently delivered by Seller under the Base Confirmation (i) the “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and the rules promulgated thereunder) of Shares by Barclays, any of its affiliates’ business units

subject to aggregation with Barclays for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Barclays with respect to “beneficial ownership” of any Shares (collectively, “Barclays Group”) would be equal to or greater than 8.5% of the outstanding Shares (an “Excess Section 13 Ownership Position”) or (ii) Barclays, Barclays Group or any person whose ownership position would be aggregated with that of Barclays or Barclays Group (Barclays, Barclays Group or any such person, a “Barclays Person”) under Section 203 of the Delaware General Corporation Law (the “DGCL Takeover Statute”) or any state or federal bank holding company or banking laws, or other federal, state or local laws, regulations or regulatory orders applicable to ownership of Shares (“Applicable Laws”), would own, beneficially own, constructively own, control, hold the power to vote or otherwise meet a relevant definition of ownership in excess of a number of Shares equal to (x) the lesser of (A) the maximum number of Shares that would be permitted under Applicable Laws and (B) the number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator, such as a state or federal banking regulator) of a Barclays Person under Applicable Laws (including, without limitation, “interested stockholder” or “acquiring person” status under the DGCL Takeover Statute) and with respect to which such requirements have not been met or the relevant approval has not been received or that would give rise to any consequences under the constitutive documents of Counterparty or any contract or agreement to which Counterparty is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination (such condition described in clause (ii), an “Excess Regulatory Ownership Position”). If any delivery owed to Barclays hereunder is not made, in whole or in part, as a result of this provision, Counterparty’s obligation to make such delivery shall not be extinguished and Counterparty shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Barclays gives notice to Counterparty that such delivery would not result in (x) Barclays Group directly or indirectly so beneficially owning in excess of 8.5% of the outstanding Shares or (y) the occurrence of an Excess Regulatory Ownership Position.

ANNEX A

PRIVATE PLACEMENT PROCEDURES

If Counterparty delivers Restricted Shares pursuant to Section 10 above (a “Private Placement Settlement”), then:

(a) the delivery of Restricted Shares by Counterparty shall be effected in accordance with customary private placement procedures for issuers comparable to Counterparty with respect to such Restricted Shares reasonably acceptable to Barclays. Counterparty shall not take, or cause to be taken, any action that would make unavailable either the exemption pursuant to Section 4(2) of the Securities Act for the sale by Counterparty to Barclays (or any affiliate designated by Barclays) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Barclays (or any such affiliate of Barclays);

(b) as of or prior to the date of delivery, Barclays and any potential purchaser of any such Restricted Shares from Barclays (or any affiliate of Barclays designated by Barclays) identified by Barclays shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for similarly-sized private placements of equity securities for issuers comparable to Counterparty (including, without limitation, the right to have made available to them for inspection all financial and other records, pertinent corporate documents and other information reasonably requested by them); provided that, prior to receiving or being granted access to any such information, any such potential purchaser may be required by Counterparty to enter into a customary non-disclosure agreement with Counterparty in respect of any such due diligence investigation;

(c) as of the date of delivery, Counterparty shall enter into an agreement (a “Private Placement Agreement”) with Barclays (or any affiliate of Barclays designated by Barclays) in connection with the private placement of such Restricted Shares by Counterparty to Barclays (or any such affiliate) and the private resale of such Restricted Shares by Barclays (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities for issuers comparable to Counterparty, in form and substance commercially reasonably satisfactory to Barclays, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating, without limitation, to the mutual indemnification of, and contribution in connection with the liability of the parties and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters, and shall provide for the payment by Counterparty of all reasonable fees and expenses in connection with such resale, including all reasonable fees and expenses of counsel for Barclays, and shall contain representations, warranties, covenants and agreements of Counterparty customary for issuers comparable to Counterparty and reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales; and

(d) in connection with the private placement of such Restricted Shares by Counterparty to Barclays (or any such affiliate) and the private resale of such Restricted Shares by Barclays (or any such affiliate), Counterparty shall, if so requested by Barclays, prepare, in cooperation with Barclays, a private placement memorandum customary for issuers comparable to Counterparty and in form and substance reasonably satisfactory to Barclays.

In the case of a Private Placement Settlement, Barclays shall, in its good faith discretion, adjust the amount of Restricted Shares to be delivered to Barclays hereunder and/or the applicable Daily Forward Price(s) in a commercially reasonable manner to reflect the fact that such Restricted Shares may not be freely returned to securities lenders by Barclays and may only be saleable by Barclays at a discount to reflect the lack of transferability and liquidity in Restricted Shares based on actual charges incurred or discounts given.

Re: Duke Energy Corporation—Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Duke Energy Corporation, a North Carolina corporation (the “Corporation”), providing for a public offering (the “Public Offering”) of shares of the common stock (the “Common Stock”) of the Corporation (the “Shares”) pursuant to an automatic shelf Registration Statement on Form S-3 filed with the Securities and Exchange Commission (the “Commission”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date hereof and continuing to and including the date (the “Cut-off Date”) 60 days after the date of the final Prospectus covering the public offering of the shares of Common Stock of the Corporation, the undersigned will not (i) directly or indirectly offer or sell (or grant any option or warrant to offer or sell), (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Subject Shares (as defined below), whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Subject Shares or such other securities, in cash or otherwise, or any

options or warrants to purchase any Subject Shares, or any securities convertible into, exchangeable for or that represent the right to receive Subject Shares.

The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the undersigned’s Subject Shares even if such Subject Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the undersigned’s Subject Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Subject Shares.

The term “Subject Shares” means (i) the shares of Common Stock, whether now owned or hereafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the Commission and (ii) shares of Common Stock acquired prior to the Cut-Off Date pursuant to any employee or director compensation plan of the Corporation or pursuant to any employee or shareholder investment plan of the Corporation.

Notwithstanding the foregoing, the undersigned may transfer the Subject Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree(s) to be bound in writing by the restrictions set forth herein, (ii) to any member of the immediate family of the undersigned provided that the transferee or transferees agree(s) to be bound in writing by the restrictions set forth herein, (iii) to any trust or foundation, provided that the trustee of the trust or foundation agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iv) to an entity controlled by the undersigned provided the transferee or transferees agree(s) to be bound in writing by the restrictions set forth herein, (v) pursuant to the laws of testamentary or intestate descent, provided that the transferee or transferees agree(s) to be bound in writing by the restrictions set forth herein or (vi) with the prior written consent of the Representatives on behalf of the Underwriters. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. The undersigned will have at the time the undersigned acquires each of the Subject Shares, and, except as contemplated by clause (i), (ii), (iii), (iv), (v) or (vi) above, for the duration of this Lock-Up Agreement will have, good and marketable title to such Subject Shares, free and clear of all liens, encumbrances, and claims whatsoever created by the undersigned. The undersigned also agrees and consents to the entry of stop transfer instructions with the Corporation in its capacity as transfer agent and registrar against the transfer of the Subject Shares except in compliance with the foregoing restrictions.

Notwithstanding the foregoing, the undersigned may not make any transfer of the Shares under clauses (i), (ii), (iii) or (iv) above if any filing by any party (donor, donee, transferor or transferee) under Section 16(a) of the Securities Exchange Act of 1934, as amended, shall be required (or be made voluntarily) in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the 60-day period referred to above).

The undersigned understands that the Corporation and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

	Very truly yours,
