PART ONE.

BONDS OF THE 3.70% SERIES

SECTION 1. The Company hereby creates a new series of bonds to be issued under and secured by the Indenture and known as its First and Refunding Mortgage Bonds, 3.70% Series due 2047 (herein called “bonds of the 3.70% Series”) and the Company hereby establishes, determines and fixes the terms and provisions of the bonds of the 3.70% Series as hereinafter in this Part One set forth.

Each bond of the 3.70% Series shall be dated the date of its authentication (except that if any such bond shall be authenticated on any interest payment date, it shall be dated the following day) and interest shall be payable on the principal represented thereby commencing June 1, 2018, from June 1 or December 1, as the case may be, next preceding the date thereof to which interest has been paid, unless such date of authentication is prior to June 1, 2018, in which case interest shall be payable from November 14, 2017; provided , however , that interest shall be payable on each bond of the 3.70% Series authenticated after the record date (as defined in the next succeeding paragraph of this Section 1) with respect to any interest payment date and prior to such interest payment date, only from such interest payment date.

Interest on any bond of the 3.70% Series shall be paid to the person who, according to the bond register of the Company, is the registered holder of such bond of the 3.70% Series at the close of business on the applicable record date, and such interest payments shall be made by check mailed to such registered holder at his last address shown on such bond register or, at the option of the Company, by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least sixteen (16) days prior to the date of payment by the Person entitled thereto ( provided , that if the bonds of the 3.70% Series are represented by Global Securities held by the Depositary, payment may be made pursuant to the procedures of the Depositary); provided , however , that, if the Company shall default in the payment of the interest due on any interest payment date on any bond of the 3.70% Series, such defaulted interest shall be paid to the registered holder of such bond (or any bond or bonds of the 3.70% Series issued upon transfer, exchange or substitution thereof) on the date of subsequent payment of such defaulted interest or, at the election of the Company, to the person in whose name such bond (or any bond or bonds of the 3.70% Series issued upon transfer, exchange or substitution thereof) is registered on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of all bonds of the 3.70% Series not less than ten (10) days preceding such subsequent record date. The term “record date” as used in this Section 1 shall mean, with respect to any semi-annual interest payment date, the close of business on the May 15 or November 15, whether or not a business day, next preceding such interest payment date or, in the case of a payment of defaulted interest, the close of business on any subsequent record date established as provided above.

SECTION 2. All bonds of the 3.70% Series shall mature as to principal on December 1, 2047 and shall bear interest at a rate of 3.70% per annum, payable semi-annually on the first day of June and December in each year, commencing on the first day of June, 2018. Interest on the bonds of the 3.70% Series will be computed on the basis of a 360-day year consisting of twelve 30-day months.

SECTION 3. The bonds of the 3.70% Series shall be fully registered bonds, without coupons, in denominations of two thousand dollars ($2,000) and integral multiples of one thousand dollars ($1,000) in excess thereof, all such bonds to be numbered, and shall be transferable and exchangeable as provided in the form of bond set forth as Exhibit A to this supplemental indenture. The provisions of §1.19 and any other provision in the Indenture in respect of coupon bonds or reservation of coupon bond numbers shall be inapplicable to the bonds of the 3.70% Series.

SECTION 4. At any time before June 1, 2047 (the “Par Call Date”), the bonds of the 3.70% Series may be redeemed at the option of the Company, in whole or in part and from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the bonds of the 3.70% Series to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the bonds of the 3.70% Series being redeemed that would be due if the bonds of the 3.70% Series matured on the Par Call Date (exclusive of interest accrued to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, plus, in either case, accrued and unpaid interest on the principal amount of the bonds of the 3.70% Series being redeemed to, but excluding, the date of such redemption. The Company shall notify the Trustee of the redemption price with respect to any redemption pursuant to this paragraph promptly after the calculation thereof. The Trustee shall not be responsible for calculating said redemption price.

At any time on or after the Par Call Date , the bonds of the 3.70% Series may be redeemed at the option of the Company, in whole or in part and from time to time, at a redemption price equal to 100% of the principal amount of the bonds of the 3.70% Series to be redeemed plus accrued and unpaid interest on the principal amount being redeemed to, but excluding, the date of such redemption.

The bonds of the 3.70 % Series are also subject to redemption through the operation of the Replacement Fund provided in Part Two of this supplemental indenture or through the application of moneys paid to the Trustee pursuant to the provisions of §5.05 of the Indenture, at any time or from time to time prior to maturity, upon prior notice as hereinafter provided, at the redemption prices specified in the fifth paragraph of the reverse side of the form of bond set forth as Exhibit A to this supplemental indenture, together with interest accrued thereon to the date fixed for redemption thereof.

In the event that any redemption date is not a business day, the Company shall pay the redemption price on the next business day without any interest or other payment due to the delay.

All such redemptions of bonds of the 3.70 % Series shall be effected as provided in Article 3 of the Indenture except that, in case a part only of the bonds of the 3.70% Series is to be paid and redeemed, the particular bonds or part thereof shall be selected by the Trustee in such manner as the Trustee in its uncontrolled discretion shall determine to be fair and in any case where several bonds are registered in the same name, the Trustee may treat the aggregate principal amount so registered as if it were represented by one bond and except that when bonds are redeemed in part only the notice given to any particular holder need state only the principal amount of the bonds of that holder which is to be redeemed and except that notice to the holders of bonds to be redeemed shall be given by mailing to such holders a notice of such redemption, first class mail postage prepaid, not later than the tenth day, and not earlier than the sixtieth day, before the date fixed for redemption, at their last addresses as they shall appear upon the bond register of the Company. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the holder receives such notice; and failure duly to give

such notice by mail, or any defect in such notice, to the holder of any bond designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other bond. No publication of notice of such redemption shall be required.

SECTION 5. The limit upon the aggregate principal amount of the bonds of the 3.70% Series which may be authenticated and delivered pursuant to this Ninety-Ninth Supplemental Indenture shall initially be $550,000,000. Notwithstanding the foregoing, the Company may, without the consent of the holders of the bonds of the 3.70% Series, reopen the bonds of the 3.70% Series and issue an unlimited amount of additional bonds having the same ranking, interest rate, maturity and other terms as the bonds of the 3.70% Series authenticated and delivered pursuant to this Ninety-Ninth Supplemental Indenture, other than, if applicable, the initial interest accrual date and interest payment date; provided, that, the Company may reopen the bonds of the 3.70% Series only if the additional bonds issued will be fungible for United States federal income tax purposes with the bonds of the 3.70% Series authenticated and delivered pursuant to this Ninety-Ninth Supplemental Indenture. Any such additional bonds will be consolidated with and form a single series of bonds under the Indenture with the bonds of the 3.70% Series authenticated and delivered pursuant to this Ninety-Ninth Supplemental Indenture.

SECTION 6. The place or places of payment (as to principal and premium, if any, and interest), redemption, transfer, exchange and registration of the bonds of the 3.70% Series shall be the office or offices or the agency or agencies of the Company in the Borough of Manhattan, The City of New York, designated from time to time by the Board of Directors of the Company (provided, that if the bonds of the 3.70% Series are represented by Global Securities held by or on behalf of the Depositary, the procedures of the Depositary may be followed for any action under this Section 6 of Part One).

SECTION 7. The form of the bonds of the 3.70% Series and the certificate of the Trustee to be endorsed on such bonds, respectively, shall be in substantially the form set forth in Exhibit A hereto.

PART TWO.

Any such affirmative vote of, or written consent given by, any holder of this bond is binding upon all subsequent holders hereof as provided in the Indenture.

In case an event of default as defined in the Indenture shall occur, the principal of all the bonds outstanding thereunder may become or be declared due and payable at the time, in the manner and with the effect provided in the Indenture.

At any time before June 1, 2047 (the “Par Call Date”), the bonds of this series may be redeemed at the option of the Company, in whole or in part and from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the bonds of this series to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on such bonds being redeemed that would be due if the bonds of this series matured on the Par Call Date (exclusive of interest accrued to the redemption date), discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, plus, in either case, accrued and unpaid interest on the principal amount of the bonds of this series being redeemed to, but excluding, the date of such redemption.

Redemption is in every case to be effected at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon at least ten, but not more than sixty, days’ prior notice, given by mail as more fully provided in the Indenture.

I am a member of the bar of the State of North Carolina and my opinion set forth herein is limited to North Carolina limited liability company law. I do not express any opinion with respect to any other law of the State of North Carolina or any other jurisdiction, or as to the effect thereof on the opinion herein stated. The Mortgage and the form of Securities do not include provisions specifying the governing law. For purposes of my opinions, I have assumed that the Mortgage and the Securities are governed exclusively by the internal substantive laws and judicial interpretations of the State of North Carolina.

In connection with this opinion, I or attorneys under my supervision (with whom I have consulted) have examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of:

(a) the registration statement on Form S-3, as amended (File No. 333-213765-05) of the Company originally filed on September 23, 2016, and subsequently filed on January 26, 2017, with the Securities and Exchange Commission (the “Commission”) under the Securities Act allowing for delayed

(f) the Articles of Organization of the Company, dated as of April 3, 2006, as amended;

(g) the Limited Liability Company Operating Agreement of the Company, dated as of April 3, 2006, as amended;

(h) an executed copy of the Underwriting Agreement;

(i) a specimen of the Securities;

(j) an executed copy of the Mortgage;

(k) an executed copy of the Supplemental Indenture;

(l) resolutions adopted by the Board of Directors of the Company, effective September 16, 2016, relating to the preparation and filing with the Commission of the Registration Statement and the issuance of the Company’s securities; and

(m) the written consent of Assistant Treasurer, John L. Sullivan, III, effective November 9, 2017, relating to the offering of the Securities.

I or attorneys under my supervision (with whom I have consulted) have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements and certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents, certificates and records as I or attorneys under my supervision (with whom I have consulted) have deemed necessary or appropriate as a basis for the opinions set forth below.

In my examination, I or attorneys under my supervision (with whom I have consulted) have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as facsimile, electronic, certified or photostatic copies, and the authenticity of such copies. In

making my examination of executed documents, I have assumed that the parties thereto, other than the Company, had the power, limited liability company or other, to enter into and perform all obligations thereunder and I have also assumed the due authorization by all requisite action, limited liability company or other, and the execution and delivery by such parties of such documents and, except to the extent expressly set forth below, the validity and binding effect thereof on such parties. As to any facts material to the opinions expressed herein which were not independently established or verified, I or attorneys under my supervision (with whom I have consulted) have relied upon oral or written statements and representations of officers and other representatives of the Company and others.

The opinion set forth below is subject to the following further qualifications, assumptions and limitations:

(i) the validity or enforcement of any agreements or instruments may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and by general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law) and

(ii) I do not express any opinion as to the applicability or effect of any fraudulent transfer, preference or similar law on any agreements or instruments or any transactions contemplated thereby.

Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth herein, I am of the opinion that the Securities have been duly authorized and executed by the Company, and that when duly authenticated by the Trustee and issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Mortgage, the Securities will constitute valid and binding obligations of the Company entitled to the benefits of the Mortgage and enforceable against the Company in accordance with their terms.

I hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement through incorporation by reference of a current report on Form 8-K. I also consent to the reference to my name under the heading “Legal Matters” in the Prospectus Supplement. In giving this consent, I do not hereby admit that I am in the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Commission promulgated thereunder. This opinion is expressed as of the date hereof unless otherwise expressly stated, and I disclaim any undertaking to advise you of any subsequent changes in the facts stated or assumed herein or of any subsequent changes in applicable laws.

	Very truly yours,

generally, and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and (y) that the provisions of the Mortgage subjecting to the lien thereof the revenues and income from the mortgaged property may not be effective prior to the delivery or taking of possession of such revenues or income or of the mortgaged property by or on behalf of the Trustee.

(j) The Bonds have been duly authorized and when executed by the Company, and when authenticated by the Trustee, in the manner provided in the Mortgage and delivered against payment therefor, will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law) and are entitled to the benefits and security afforded by the Mortgage in accordance with the terms of the Mortgage and the Bonds, except as set forth in paragraph (i) above.

(k) Any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument set forth on Annex A hereto or filed or incorporated by reference as an exhibit to the Registration Statement or the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2016 or any subsequent Quarterly Report on Form 10-Q of the Company or Current Report on Form 8-K of the Company are all indentures, mortgages, deeds of trust, loan agreements or other agreements or instruments that are material to the Company and its subsidiaries taken as a whole.

4. Offering by the Underwriters. It is understood that the several Underwriters propose to offer the Bonds for sale to the public as set forth in the Pricing Disclosure Package and the Prospectus.

5. Covenants of the Company. The Company covenants and agrees with the several Underwriters that:

(a) The Company will cause any Preliminary Prospectus and the Prospectus to be filed pursuant to, and in compliance with, Rule 424(b) of the 1933 Act Regulations, and advise the Underwriters promptly of the filing of any amendment or supplement to the Registration Statement, any Preliminary Prospectus or the Prospectus and of the institution by the Commission of any stop order proceedings in respect of the Registration Statement, and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(b) If at any time when a prospectus relating to the Bonds (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 Company 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.

(c) The Company, during the period when a prospectus relating to the Bonds is required to be delivered under the 1933 Act, will timely file all documents required to be filed with the Commission pursuant to Section 13 or 14 of the 1934 Act.

made and will not make any offer relating to the Bonds that would constitute a “free writing prospectus” as defined in Rule 405 of the 1933 Act Regulations, other than a Permitted Free Writing Prospectus or a free writing prospectus that is not required to be filed by the Company pursuant to Rule 433 of the 1933 Act Regulations (“ Rule 433 ”); any such free writing prospectus (which shall include the pricing term sheet discussed in Section 5(e) below), the use of which has been consented to by the Company and the Underwriters, is listed on Schedule B and herein is called a “ Permitted Free Writing Prospectus .” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(e) The Company agrees to prepare a pricing term sheet specifying the terms of the Bonds not contained in any Preliminary Prospectus, substantially in the form of Schedule C hereto and approved by the Representatives on behalf of the Underwriters, and to file such pricing term sheet as an “issuer free writing prospectus” pursuant to Rule 433 prior to the close of business two business days after the date hereof.

(f) The Company agrees that if at any time following the issuance of a Permitted Free Writing Prospectus any event occurs as a result of which such Permitted Free Writing Prospectus 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 Company will give prompt notice thereof to the Underwriters and, if requested by the Underwriters, will prepare and furnish without charge to each Underwriter 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.

(g) The Company will make generally available to its security holders, in each case as soon as practicable but not later than 60 days after the close of the period covered thereby, earnings statements (in form complying with the provisions of Rule 158 under the 1933 Act, which need not be certified by independent certified public accountants unless required by the 1933 Act) covering (i) a twelve-month period beginning not later than the first day of the Company’s fiscal quarter next following the effective date of the Registration Statement and (ii) a twelve-month period beginning not later than the first day of the Company’s fiscal quarter next following the date of this Agreement.

(h) The Company will furnish to you, without charge, copies of the Registration Statement (three of which will include all exhibits other than those incorporated by reference), the Pricing Disclosure Package and the Prospectus, and all

amendments and supplements to such documents, in each case as soon as available and in such quantities as you reasonably request.

(i) The Company will arrange or cooperate in arrangements for the qualification of the Bonds for sale under the laws of such jurisdictions as you designate and will continue such qualifications in effect so long as required for the distribution; provided, however, that the Company shall not be required to qualify as a foreign limited liability company or to file any general consents to service of process under the laws of any state where it is not now so subject.

(j) The Company will pay all expenses incident to the performance of its obligations under this Agreement including (i) the printing and filing of the Registration Statement and the printing of this Agreement and any Blue Sky Survey, (ii) the preparation and printing of certificates for the Bonds, (iii) the issuance and delivery of the Bonds as specified herein, (iv) the fees and disbursements of counsel for the Underwriters in connection with the qualification of the Bonds under the securities laws of any jurisdiction in accordance with the provisions of Section 5(i) and in connection with the preparation of the Blue Sky Survey, such fees not to exceed $5,000, (v) the printing and delivery to the Underwriters, in quantities as hereinabove referred to, of copies of the Registration Statement and any amendments thereto, of any Preliminary Prospectus, of the Prospectus, of any Permitted Free Writing Prospectus and any amendments or supplements thereto, (vi) any fees charged by independent rating agencies for rating the Bonds, (vii) any fees and expenses in connection with the listing of the Bonds on the New York Stock Exchange, (viii) any filing fee required by the Financial Industry Regulatory Authority, Inc. (ix) the costs of any depository arrangements for the Bonds with DTC or any successor depositary and (x) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Bonds, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the Underwriters and officers of the Company and any such consultants, and the cost of any aircraft chartered in connection with the road show; provided, however, the Underwriters shall reimburse a portion of the costs and expenses referred to in this clause (x).

6. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Bonds will be subject to the accuracy of the representations and warranties on the part of the Company herein, to the accuracy of the statements of officers of the Company made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

(a) The Prospectus shall have been filed by the Company with the Commission pursuant to Rule 424(b) within the applicable time period prescribed for filing by the 1933 Act Regulations and in accordance herewith and each Permitted Free

Writing Prospectus shall have been filed by the Company with the Commission within the applicable time periods prescribed for such filings by, and otherwise in compliance with, Rule 433.

(b) On or after the Applicable Time and prior to the Closing Date, no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose or pursuant to Section 8A of the 1933 Act shall have been instituted or, to the knowledge of the Company or you, shall be threatened by the Commission.

(e) You shall have received an opinion of Robert T. Lucas III, Esq., Deputy General Counsel of Duke Energy Business Services LLC, the service company subsidiary of Duke Energy Corporation (who in such capacity provides legal services to the Company) (or other appropriate counsel reasonably satisfactory to the Representatives, which may include Duke Energy Corporation’s other “in-house” counsel), dated the Closing Date, to the effect that:

(i) The Company has been duly organized and is validly existing as a limited liability company in good standing under the law of the State of North Carolina, with power and authority (limited liability company and other) to own its properties and conduct its business as described in the Pricing Disclosure Package and the Prospectus and to enter into and perform its obligations under this Agreement.

(ii) The Company 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 Company.

(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 Company or any of its 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 has been duly authorized, executed and delivered by the Company.

(vi) The issue and sale of the Bonds by the Company and the execution, delivery and performance by the Company of this Agreement, the Mortgage and the Bonds will not contravene any of the provisions of the Articles of Organization or the Operating Agreement, the North Carolina Limited Liability Company Act 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 Company or any of its 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 to which the Company is a party or by which it or its property is bound or to which any of its property or assets is subject or any instrument filed or incorporated by reference as an exhibit to the Annual Report on Form 10-K of the Company for the fiscal year ended December 31, 2016 or the Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2017, June 30, 2017 and September 30, 2017 of the Company or any Current Report on Form 8-K of the Company with an execution or filing date after December 31, 2016 or identified in Annex A to this Agreement, which affects in a material way the Company’s ability to perform its obligations under this Agreement, the Mortgage or the Bonds.

(vii) The North Carolina Utilities Commission and the Public Service Commission of South Carolina have issued appropriate orders with respect to the issuance and sale of the Bonds in accordance with this Agreement, and, to the best of such counsel’s knowledge, such orders are still in

effect; the issuance and sale of the Bonds to the Underwriters are in conformity with the terms of such orders.

(viii) The Mortgage has been duly authorized, executed and delivered by the Company and qualified under the 1939 Act, and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company, enforceable against the Company in accordance with its terms, except (x) as the same may be limited by the laws of the States of North Carolina and South Carolina (in which States such counsel is advised all physical property of the Company subject to the Mortgage is located except for certain interconnection lines) with respect to or affecting the remedies to enforce the security provided by the Mortgage, which laws do not, in the opinion of such counsel, make inadequate the remedies necessary for the realization of the benefits of such security, and (y) that the provisions of the Mortgage subjecting to the lien thereof the revenues and income from the mortgaged property may not be effective prior to the delivery or taking of possession of such revenues or income or of the mortgaged property by or on behalf of the Trustee.

(ix) The Bonds have been duly authorized, executed and issued by the Company and, when the same have been authenticated by the Trustee as specified in the Mortgage and delivered against payment therefor, will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, and are entitled to the benefits and security afforded by the Mortgage in accordance with the terms of the Mortgage and the Bonds, except as set forth in paragraph (viii) above.

(x) The Company has good title to all properties owned by it, subject only (a) to the lien of the Mortgage, (b) to permitted encumbrances as defined in the Mortgage, (c) to minor exceptions and defects which do not, in the aggregate, in the opinion of such counsel, materially interfere with the use by the Company of such properties for the purposes for which they are held, materially detract from the value of said properties or in any material way impair the security afforded by the Mortgage, and (d) in the case of the Company’s existing hydroelectric plants, to provisions of licenses issued by the Federal Power Commission or the Federal Energy Regulatory Commission and to the provisions of the Federal Power Act.

(xi) The Mortgage complies as to form with all applicable laws of the states wherein the properties subjected or intended to be subjected to the lien of the Mortgage are located, including all applicable recording laws, and constitutes a valid, direct first mortgage lien on all properties and franchises purported to be owned by the Company, except such property as is specifically excepted from the lien thereof, subject only to the liens, charges and encumbrances stated in paragraph (x) above; all fixed electric

properties hereafter acquired by the Company will, upon such acquisition, become subject to the lien of the Mortgage, subject, however, to liens or charges of the character permitted to exist by the Mortgage, and to liens, if any, existing or placed on such property at the time of the acquisition thereof by the Company, and the description of such property and franchises in the Mortgage is adequate to constitute a lien on such property and franchises of the Company except as aforesaid.

(xii) The Original Mortgage and the supplemental indentures thereto, other than the Supplemental Indenture have been duly recorded or filed for recordation in all such offices as are necessary to perfect and to preserve and protect the lien of the Mortgage upon the property intended to be subjected to the lien thereof, and upon the filing and recording of the Supplemental Indenture, no other recording or any periodic or other refiling or rerecording of the Mortgage is or will be required in order to perfect and to preserve and protect the lien of the Mortgage upon such property, and there are no mortgage, recording or other taxes required to be paid in connection with such filing and recording or in connection with the issuance of the Bonds other than customary filing and recording fees.

(xiii) No consent, approval, authorization, order, registration or qualification of or with any federal, North Carolina or South Carolina governmental agency or body or, to such counsel’s knowledge, any federal or North Carolina court, which has not been obtained or taken and is not in full force and effect, is required to authorize or for the Company to consummate the transactions contemplated by this 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 Bonds by the Underwriters.

Such counsel may state that such counsel’s opinions in paragraphs (viii) and (ix) above are subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, and by general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law) and to an implied covenant of good faith and fair dealing. Such counsel may also state that such counsel’s opinion in paragraph (x) above is based upon the Company’s title insurance. Such counsel shall state that nothing has come to such counsel’s attention that has caused such counsel 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 such counsel’s attention that has caused such counsel to believe that (i) the Registration Statement as of the 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, or at the Closing Date, 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, such counsel 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, or excluded therefrom, including XBRL interactive data, (ii) the statement of the eligibility and qualification of the Trustee included in the Registration Statement (the “ Form T-1 ”) or (iii) the information in the Prospectus under the caption “Book-Entry System.”

In rendering the foregoing opinion, such counsel may state that such counsel 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 the law of the State of South Carolina, and may rely as to all matters of the law of the State of South Carolina on the opinion of Karol P. Mack, Esq., Associate General Counsel of Duke Energy Business Services LLC, the service company subsidiary of Duke Energy Corporation (who in such capacity provides legal services to the Company) (or other appropriate counsel reasonably satisfactory to the Representatives, which may include Duke Energy Corporation’s other “in-house” counsel). Such counsel may also state that such counsel has relied as to certain factual matters on information obtained from public officials, officers of the Company and other sources believed by such counsel to be responsible.

(f) You shall have received an opinion of Hunton & Williams LLP, counsel to the Company, dated the Closing Date, to the effect that:

(i) The statements set forth (i) under the caption “Description of First and Refunding Mortgage Bonds” in the Base Prospectus and (ii) under the caption “Description of the Mortgage Bonds” in the Pricing Disclosure Package and the Prospectus, insofar as such statements purport to summarize certain provisions of the Mortgage and the Bonds, fairly summarize such provisions in all material respects.

(ii) 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 by the Company or the consummation by the Company of the transactions contemplated hereby.

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

(iv) The execution and delivery by the Company of this Agreement and the consummation by the Company of the transactions contemplated thereby, including the issuance and sale of the Bonds, will not violate or conflict with, or result in any contravention of, any Applicable Laws of the States of North Carolina and New York.

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

(vi) The statements set forth in the Pricing Disclosure Package and the Prospectus under the caption “Certain 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.

In rendering the foregoing opinions, Hunton & Williams LLP may state that (i) “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 Company 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 Company) in the transactions contemplated by this Agreement or because of such parties’ legal or regulatory status or because of any other facts specifically pertaining to such parties; (ii) “Governmental Authorities” means any court, regulatory body, administrative agency or governmental body of the States of North Carolina and New York having jurisdiction over the Company under Applicable Laws and the Federal Energy Regulatory Commission, but excluding the North Carolina Utilities Commission and the New York State Public Service Commission; and (iii) “Applicable Laws” means those laws, rules and regulations of the States of North Carolina and New York that, in such counsel’s experience, are normally applicable to transactions of the type contemplated by this Agreement (other than state securities or blue sky laws, antifraud laws, 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 such counsel having made any special investigation as to the applicability of any specific law, rule or regulation, and the Federal Power Act and the rules and regulations of the Federal Energy Regulatory Commission thereunder. In addition, such counsel may state that they have relied as to certain factual matters on information obtained from public officials, officers and representatives

of the Company and that the signatures on all documents examined by them are genuine, assumptions which such counsel have not independently verified.

You shall also have received a statement of Hunton & Williams LLP, dated the Closing Date, 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 Company 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, compliance with XBRL interactive data requirements or the Form T-1) (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 Rules and 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, compliance with XBRL interactive data requirements or the Form T-1) 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 the Closing Date, 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 that part of the Registration Statement that constitutes the statement of eligibility on the Form T-1). 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 that part of the Registration Statement that constitutes the statement of eligibility on the Form T-1).

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 factual matters contained in the representations and warranties of the Company set forth in Section 2(d) of this Agreement, the Registration Statement became effective upon filing with the Commission pursuant to Rule 462 of the 1933 Act Regulations and, pursuant to Section 309 of the 1939 Act, the Mortgage has been qualified under the 1939 Act, 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.

In addition, such counsel may state that such counsel does not pass upon, or assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Pricing Disclosure Package or the Prospectus and has made no independent check or verification thereof (except to the limited extent referred to in Section 6(f)(i) above).

(g) You shall have received an opinion of Sidley Austin LLP, counsel for the Underwriters, dated the Closing Date, with respect to the validity of the Bonds, the effectiveness of 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 Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. In giving their opinion, Sidley Austin LLP may rely on the opinion of Robert T. Lucas III, Esq. as to matters of North Carolina law and on the opinion of Karol P. Mack, Esq., Associate General Counsel of Duke Energy Business Services, LLC, the service company subsidiary of Duke Energy Corporation (or other appropriate counsel reasonably satisfactory to the Representatives) as to matters of South Carolina law.

(h) On or after the date hereof, there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally or of the securities of the Company or Duke Energy Corporation, on the New York Stock Exchange; or (ii) a general moratorium on commercial banking activities in New York declared by either Federal or New York State authorities or a material

disruption in commercial banking services or securities settlement or clearance services in the United States; or (iii) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, if the effect of any such event specified in this subsection (h) in your reasonable judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Bonds 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 7 hereof and except for the expenses to be borne by the Company as provided in Section 5(j) hereof.

(i) You shall have received a certificate of the Chairman of the Board, the President, any Vice President, the Secretary or an Assistant Secretary and any financial or accounting officer of the Company, dated the Closing Date, in which such officers, to the best of their knowledge after reasonable investigation, shall state that the representations and warranties of the Company in this Agreement are true and correct as of the Closing Date, that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to the Closing Date, that the conditions specified in Section 6(c) and Section 6(d) have been satisfied, and that no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are threatened by the Commission.

(j) At the time of the execution of this Agreement, you shall have received a letter dated such date, in form and substance satisfactory to you, from Deloitte & Touche LLP, the Company’s independent registered public accounting firm, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in or incorporated by reference into the Registration Statement, the Pricing Disclosure Package and the Prospectus, including specific references to inquiries regarding any increase in long-term debt (excluding current maturities), decrease in net current assets (defined as current assets less current liabilities) or member’s equity, and decrease in operating revenues or net income for the period subsequent to the latest financial statements incorporated by reference in the Registration Statement when compared with the corresponding period from the preceding year, as of a specified date not more than three business days prior to the date of this Agreement.

(k) At the Closing Date, you shall have received from Deloitte & Touche LLP, a letter dated as of the Closing Date, to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (j) of this Section 6, except that the specified date referred to shall be not more than three business days prior to the Closing Date.

The Company will furnish you with such conformed copies of such opinions, certificates, letters and documents as you reasonably request.

7. Indemnification. (a) The Company agrees to indemnify and hold harmless each Underwriter, their respective 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) or any Permitted Free Writing Prospectus, 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 Company 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;

(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 Company; 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 7.

In no case shall the Company be liable under this indemnity agreement with respect to any claim made against any Underwriter or any such controlling person unless the Company 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 Company shall not relieve it from any liability which it may have otherwise than under subsections 7(a) and 7(b). The Company 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 Company 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 Company and such Underwriter or such controlling person shall have been advised by such counsel that a conflict of interest between the Company 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 Company 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 Company 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 Company within the meaning of Section 15 of the 1933 Act, in connection with the sale of the Bonds.

(b) Each Underwriter severally agrees that it will indemnify and hold harmless the Company, its directors and each of the officers of the Company who signed the Registration Statement and each person, if any, who controls the Company 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 Company 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 Company 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 Company, and the Company and each person so indemnified shall have the rights and duties given to the Underwriters, by the provisions of subsection (a) of this Section.

(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 7 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 Company on the one hand and the Underwriters on the other from the offering of the Bonds. 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 Company on the one hand and the Underwriters 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 Company on the one hand and the Underwriters 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 Company 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. 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 Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters 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 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 shall be required to contribute any amount in excess of the amount by which the total price at which the Bonds underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter 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’ obligations to contribute are several in proportion to their respective underwriting obligations and not joint.

8. Default by One or More of the Underwriters. (a) If any Underwriter shall default in its obligation to purchase the principal amount of the Bonds which it has agreed to purchase hereunder on the Closing Date, you may in your discretion arrange for you or another party or other parties to purchase such Bonds 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 Bonds, then the Company 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 Bonds on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Bonds, or the Company notifies you that it has so arranged for the purchase of such Bonds, you or the Company shall have the right to postpone such Closing Date 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 Company 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 Bonds.

(b) If, after giving effect to any arrangements for the purchase of the Bonds of a defaulting Underwriter or Underwriters by you or the Company as provided in subsection (a) above, the aggregate amount of such Bonds which remains unpurchased does not exceed one-tenth of the aggregate amount of all the Bonds to be purchased at such Closing Date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the amount of Bonds which such Underwriter agreed to purchase hereunder at such Closing Date and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the amount of Bonds which such Underwriter agreed to purchase hereunder) of the Bonds 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 Bonds of a defaulting Underwriter or Underwriters by you or the Company as provided in subsection (a) above, the aggregate amount of such Bonds which remains unpurchased exceeds one-tenth of the aggregate amount of all the Bonds to be purchased at such Closing Date, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase the Bonds of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company as provided in Section 5(j) hereof and the indemnity and contribution agreement in Section 7 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

9. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters 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 or the Company, or any of its officers or directors or any controlling person, and will survive delivery of and payment for the Bonds.
