(k) The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Bonds that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission; provided, however, that the prior written consent of the Representatives and the Company shall be deemed to have been given in respect of the Issuer Free Writing Prospectuses included in Schedule II hereto; and provided further, however, that prior to the preparation of the Final Term Sheet in accordance with Section 5(b), the Underwriters are authorized to use the information with respect to the final terms of the Bonds in communications conveying information relating to the offering to investors. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.”

6. The Company covenants and agrees with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of

the Company’s counsel and accountants in connection with the registration of the Bonds under the Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, the Preliminary Prospectus, any Permitted Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any Agreement among Underwriters, this Agreement, the Indenture, any Blue Sky and Legal Investment Memoranda, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Bonds; (iii) all expenses in connection with the qualification of the Bonds for offering and sale under state securities laws as provided in Section 5(d) hereof, including the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky and Legal Investment Surveys; (iv) any fees charged by securities rating services for rating the Bonds; (v) any filing fees incident to, and the reasonable fees and disbursements of counsel for the Underwriters in connection with, any required review by The Financial Industry Regulatory Authority (“FINRA”) of the terms of the sale of the Bonds; (vi) the cost of preparing the Bonds; (vii) the fees and expenses of the Trustee and any agent of the Trustee and the reasonable fees and disbursements of counsel for the Trustee in connection with the Indenture and the Bonds; (viii) any fees and expenses in connection with listing the Bonds and the cost of registering the Bonds under Section 12 of the Exchange Act; and (ix) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that except as provided in this Section, and Sections 8 and 11 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Bonds by them and any advertising expenses connected with any offers they may make.

7. The obligations of the Underwriters shall be subject, in the discretion of the Representatives, to the condition that all representations and warranties and other statements of the Company in or incorporated by reference in this Agreement are, at and as of the Time of Delivery, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

(a) The Prospectus as amended or supplemented shall have been filed with the Commission pursuant to Rule 424(b) within the applicable time period prescribed for such filing (without reliance on Rule 424(b)(8) of the Rules and Regulations and in accordance with Section 5(a) hereof); if the Company has elected to rely upon Rule 462(b), the Rule 462(b) Registration Statement shall have become effective by 10:00 P.M., Washington, D.C. time, on the date hereof; no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for that purpose shall have been initiated or threatened by the Commission; and all requests for additional information on the part of the Commission shall have been complied with to the Representatives’ reasonable satisfaction.

(b) Counsel for the Underwriters shall have furnished to the Representatives such written opinion or opinions, dated the Time of Delivery, with respect to the Registration Statement and the Prospectus as amended or supplemented, as well as such other related matters as the Representatives may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters.

(c) Xxxx X. Xxxx, Chief Corporate Counsel of Sempra Energy, a California corporation and the ultimate parent of the Company, shall have furnished to the Representatives a written opinion, dated the Time of Delivery, in form and substance satisfactory to the Representatives, to the effect that:

(i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of California, with power and authority (corporate and other) to own its properties and conduct its business as described in the Pricing Disclosure Package and the Prospectus, and has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, except where the failure to be so qualified would not subject it to material liability or disability;

(ii) The Company has an authorized capitalization as set forth in the Pricing Disclosure Package and the Prospectus and all of the issued shares of capital stock of the Company have been duly and validly authorized and issued and are fully paid and non-assessable;

(iii) To the best of such counsel’s knowledge and other than as set forth or incorporated by reference in the Pricing Disclosure Package and the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject which, if determined adversely to the Company or any of its subsidiaries, would reasonably be expected, individually or in the aggregate, to have a material adverse effect on the consolidated financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole; and, to the best of such counsel’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others;

(iv) This Agreement has been duly authorized, executed and delivered by the Company;

(v) The Bonds have been duly authorized, executed, authenticated, issued and delivered by the Company and the Bonds and the Indenture conform to the descriptions thereof in the Pricing Disclosure Package and the Prospectus;

(vi) The Indenture has been duly authorized, executed and delivered by the Company; and the Indenture has been duly qualified under the Trust Indenture Act;

(vii) The Company and its subsidiaries hold all franchises, certificates of public convenience and necessity, permits, licenses and easements necessary to

own, operate and maintain their properties as described in the Prospectus except to the extent that such failure, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on the consolidated financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole;

(viii) The Base Indenture and each Supplemental Indenture has been duly recorded (or arrangements have been made for the prompt recording) in all offices of county recorders or clerks of all counties in the State of California and the State of Arizona in which any real property subject to the lien of the Indenture is located and appropriate financing statements in respect of personal property and fixtures have been filed in the Office of the Secretary of State of the State of California and the Office of the Secretary of State of the State of Arizona and no other filing or recordation is necessary for the perfection and preservation of the lien created thereby except for recordations required in respect of after-acquired real property;

(ix) The Indenture constitutes, as security for the Bonds, a valid and subsisting first lien to the extent that it purports to be such on all the present properties of the Company (including plants, machinery, equipment, real estate and fixed property described above), rights and franchises of the Company (other than those properties excepted or released from the lien of the Indenture by its terms) subject only to Permissible Encumbrances and other liens and charges permitted by the Indenture and such liens, charges and encumbrances, defects, qualifications, exceptions and other matters as are set forth or referred to in the Prospectus, or which do not, in such counsel’s opinion, materially affect the security for the Bonds, and upon acquisition thereafter by the Company of similar properties the Indenture will, subject to liens existing thereon at the time of acquisition, create such lien thereon;

(x) The issue and sale of the Bonds and the compliance by the Company with all of the provisions of the Bonds, the Indenture and this Agreement and the consummation of the transactions herein and therein contemplated will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material contract, indenture, mortgage, deed of trust, loan agreement, note, lease or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of its material properties or assets is subject, nor will such actions result in any violation of the provisions of the Articles of Incorporation or Bylaws of the Company or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its material properties;

(xi) No consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body having jurisdiction over the Company or any of its material properties is required for the issuance and sale of the Bonds or the consummation by the Company of the

transactions contemplated by this Agreement or the Indenture, except such as have been obtained under the Act, the Trust Indenture Act and from the Public Utilities Commission of the State of California and 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 Bonds by the Underwriters; the Public Utilities Commission of the State of California has duly authorized the issuance and sale of the Bonds by the Company on the terms set forth in the Pricing Disclosure Package and Prospectus and in this Agreement and such authorizations are in full force and effect;

(xii) The Company is not (i) in violation of its Articles of Incorporation or Bylaws or (ii) in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan agreement, note, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound, except in the case of clause (ii) for such defaults which, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on the consolidated financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole;

(xiii) The statements set forth in the Pricing Disclosure Package and the Prospectus as amended or supplemented under the captions “Description of First Mortgage Bonds” and “Supplemental Description of First Mortgage Bonds,” insofar as they purport to constitute a summary of the terms of the Bonds or the Indenture, and under the captions “Plan of Distribution” and “Underwriting,” insofar as they purport to describe the provisions of the laws and documents referred to therein, are accurate and fair in all material respects;

(xiv) The Company is not, and after giving effect to the offering and sale of the Bonds, will not be, an “investment company,” as such term is defined in the Investment Company Act;

(xv) The documents incorporated by reference in the Pricing Disclosure Package and the Prospectus as amended or supplemented (other than the financial statements and related schedules therein, as to which such counsel need express no opinion), when they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the requirements of the Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder, and such counsel has no reason to believe that any of such documents, when they became effective or were so filed, as the case may be, contained, in the case of a registration statement which became effective under the Act, 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, in the case of other documents which were filed under the Act or the Exchange Act with the Commission, 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 when such documents were so filed, not misleading; it being understood that such counsel expresses no belief with respect to the financial statements or schedules or other financial data included or incorporated by reference in, or omitted from, the Prospectus as amended or supplemented; and

(xvi) The Registration Statement and the Prospectus as amended or supplemented and any further amendments and supplements thereto made by the Company prior to the Time of Delivery (in each case, excluding the documents incorporated by reference therein) comply as to form in all material respects with the requirements for registration statements on Form S-3 under the Act, and the requirements under the Trust Indenture Act and the rules and regulations of the Commission thereunder, it being understood, however, that such counsel expresses no opinion with respect to Regulation S-T or the financial statements, schedules or other financial data included or incorporated by reference in, or omitted from, the Registration Statement or the Prospectus as amended or supplemented or with respect to any Form T-1. In passing upon the compliance as to the form of the Registration Statement and the Prospectus as amended or supplemented (in each case, excluding the documents incorporated by reference therein), except for those statements referred to in the opinion in subsection (xiii) of this Section 7(c), such counsel has assumed that the statements made and incorporated by reference therein are correct and complete.

(d) Counsel for the Company satisfactory to the Representatives shall have furnished to the Representatives their written opinion or opinions, dated the Time of Delivery, in form and substance satisfactory to the Representatives, to the effect that:

(i) The Indenture, as supplemented by the applicable Supplemental Indenture, has been qualified under the Trust Indenture Act;

(ii) Each of the Indenture, assuming the due authorization, execution and delivery thereof, is, and the Supplemental Indenture dated as of May 14, 2009, upon due execution and delivery thereof, will be, the legally valid and binding agreement of the Company, enforceable against the Company in accordance with its terms;

(iii) The Bonds, when executed, issued and authenticated in accordance with the terms of the Indenture, and delivered to and paid for by the Underwriters in accordance with the terms of this Agreement, will be the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms. A registered holder of the Bonds will be a beneficiary under the Indenture, as supplemented by the Supplemental Indenture dated as of May 14, 2009;

(iv) The Registration Statement, as of the date it was declared effective, and the Prospectus, as of its date (in each case, excluding the documents incorporated by reference therein), each appeared on its face to be appropriately responsive in all material respects to the applicable form requirements for

registration statements on Form S-3 under the Act, and the requirements under the Trust Indenture Act and the rules and regulations of the Commission thereunder; it being understood, however, that such counsel expresses no opinion with respect to Regulation S-T or the financial statements, schedules, or other financial data included in, incorporated by reference in, or omitted from, the Registration Statement or the Prospectus or with respect to any Form T-1. For purposes of this paragraph, such counsel has assumed that the statements made in the Registration Statement and the Prospectus are correct and complete; and

(v) The Registration Statement has become effective under the Act, and, based solely on telephone conversations with representatives of the Commission, no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated by the Commission. Any required filing of the Prospectus pursuant to Rule 424(b) under the Act has been made in accordance with Rules 424(b) and 430B under the Act and the Final Term Sheet has been filed pursuant to Rule 433 under the Act in accordance with Rule 433(d).

In addition, such counsel shall provide a statement to the effect that such counsel has participated in conferences and telephone conversations with officers and other representatives of the Company, the independent public accountants for the Company and representatives of the Underwriters, during which the contents of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus as amended or supplemented and related matters were discussed and, although such counsel is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement and the Prospectus as amended or supplemented and has not made any independent check or verification thereof, during the course of such participation, no facts came to such counsel’s attention that caused them to believe that:

(i) the Registration Statement, as of the date of the Prospectus, including the information deemed to be a part of the Registration Statement pursuant to Rule 430B under the Act (together with the documents incorporated therein), 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;

(ii) the Pricing Disclosure Package, at the Applicable Time (together with the documents incorporated therein), contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

(iii) the Prospectus, as of its date or as of the Time of Delivery (together with the documents incorporated therein), contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that such counsel expresses no belief with respect to the financial statements, schedules or other financial data included or incorporated by reference in, or omitted from, the Registration Statement or the Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, any documents incorporated by reference therein or any Form T-1.

(e) On the date hereof at a time prior to the execution of this Agreement, and at the Time of Delivery, Deloitte & Touche LLP shall have furnished to the Representatives a letter, dated the date hereof, in form and substance satisfactory to the Representatives, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters, and a letter dated the Time of Delivery reaffirming the statements made in their letter dated the date hereof, except that the specified date referred to in such letter delivered on the Time of Delivery shall be a date not more than three days prior to the Time of Delivery, and with respect to such letter dated the Time of Delivery, as to such other matters as the Representatives may reasonably request and in form and substance satisfactory to the Representatives.

(f)(i) The Company and its subsidiaries, taken as a whole shall have not sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus as amended prior to the date hereof any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Pricing Disclosure Package and the Prospectus as amended prior to the date hereof, and (ii) since the respective dates as of which information is given in the Pricing Disclosure Package and the Prospectus as amended prior to the date hereof there shall not have been any change in the capital stock or long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, shareholders’ equity or results of operations of the Company or any of its subsidiaries, otherwise than as set forth or contemplated in the Pricing Disclosure Package and the Prospectus as amended prior to the date hereof, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse to the Company and its subsidiaries, taken as a whole, as to make 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 as first amended or supplemented.

(g) At or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded any of the Company’s secured debt by any “nationally recognized statistical rating organization,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s secured debt.

(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 on the New York Stock Exchange; (ii) a suspension or material limitation in trading in the Company’s securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York or California State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; or (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, if the effect of any such event specified in this clause (iv) in the judgment of the Representatives 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 as first amended or supplemented.

(i) The Company shall have complied with the provisions of Section 5(e) hereof with respect to the furnishing of prospectuses on the New York business day next succeeding the date hereof.

(j) The Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery a certificate of officers of the Company satisfactory to the Representatives as to the accuracy of the representations and warranties of the Company herein at and as of the Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to the Time of Delivery, as to the matters set forth in subsections (a) and (f) of this Section and as to such other matters as the Representatives may reasonably request.

8.(a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the Bonds, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the Bonds or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Prospectus as amended or supplemented.

(b) Each Underwriter severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the Bonds, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the Bonds or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party under such subsection to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnified party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Representatives shall have the right to employ counsel to represent jointly the Underwriters and their respective officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under this Section 8, if the Representatives shall have reasonably concluded that there may be one or more legal defenses available to the Underwriters and their respective officers, employees and controlling persons that are different from or additional to those available to the Company and its officers, employees and controlling persons, and the fees and expenses of a single separate counsel (in addition to local counsel) shall be paid by the

Company. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) 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 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (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 contemplated by this Agreement. 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 under subsection (c) 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 losses, claims, damages or liabilities (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 of the Bonds contemplated by this Agreement (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. 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 contribution pursuant to this subsection (d) 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 subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) 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 subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the applicable 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters in this subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to the Bonds and not joint.

(e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

9.(a) If any Underwriter shall default in its obligation to purchase the Bonds which it has agreed to purchase under this Agreement, the Representatives may in their discretion arrange for themselves 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 the Representatives 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 the Representatives to purchase such Bonds on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Bonds, or the Company notifies the Representatives that it has so arranged for the purchase of such Bonds, the Representatives or the Company shall have the right to postpone the 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 or the Prospectus as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. 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.

(b) If, after giving effect to any arrangements for the purchase of the Bonds of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of the Bonds which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Bonds, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Bonds which such Underwriter agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Bonds which such Underwriter agreed to purchase under this Agreement) 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 the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Bonds which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Bonds, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase 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 and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Bonds.

11.

The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.
