1. Particular sales of Designated Bonds may be made from time to time to the Underwriters of such First Mortgage Bonds, for whom the firms designated as representatives of the Underwriters of such First Mortgage Bonds in the Pricing Agreement relating thereto will act as representatives (the “Representatives”). The term “Representatives” also refers to a single firm acting as sole representative of the Underwriters and to an Underwriter or Underwriters who act without any firm being designated as its or their representatives. This Underwriting Agreement shall not be construed as an obligation of the Company to sell any of the First Mortgage Bonds or as an obligation of any of the Underwriters to purchase any of the First Mortgage Bonds.

date, time and manner of delivery of such Designated Bonds and payment therefor. The Pricing Agreement shall also specify (to the extent not set forth in the Indenture and the registration statement and prospectus with respect thereto) the terms of such Designated Bonds. A Pricing Agreement shall be in the form of an executed writing (which may be in counterparts), and may be evidenced by an exchange of telegraphic communications or any other rapid transmission device designed to produce a written record of communications transmitted. The obligations of the Underwriters under this Agreement and each Pricing Agreement shall be several and not joint.

(a) The Prospectus as amended or supplemented in relation to the applicable Designated Bonds 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) by the rules and regulations under the Act 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 of the applicable Pricing Agreement; 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, dated the Time of Delivery for such Designated Bonds, 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 for such Designated Bonds, 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 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 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 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 except for such proceedings which, if determined adversely to the Company or any of its subsidiaries, would not 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 and the Pricing Agreement with respect to the Designated Bonds have been duly authorized, executed and delivered by the Company;

(v) The Designated Bonds have been duly authorized, executed, authenticated, issued and delivered by the Company and the Designated Bonds and the Indenture conform to the descriptions thereof in 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 Designated 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 Designated 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 Designated Bonds and the compliance by the Company with all of the provisions of the Designated Bonds, the Indenture, this Agreement and the Pricing Agreement with respect to the Designated Bonds 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 Designated Bonds or the consummation by the Company of the transactions contemplated by this Agreement or such Pricing 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 Designated Bonds by the Underwriters; the Public Utilities Commission of the State of California has duly authorized the issuance and sale of the Designated Bonds by the Company on the terms set forth in the 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 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 First Mortgage 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, complete and fair in all material respects;

(xiv) The Company is not, and after giving effect to the offering and sale of the Designated 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 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 other financial data included or incorporated by reference in, or omitted from, the Prospectus as amended or supplemented;

(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 for the Designated Bonds (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 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; and

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

(i) Each of the Indenture, assuming the due authorization, execution and delivery thereof, is, and the applicable Supplemental Indenture, upon due execution and delivery thereof, will be, a legally valid and binding obligation of the Company, enforceable against the Company in accordance with its terms;

(ii) The Designated 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 and the Pricing Agreement, will be legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms. A registered holder of the Designated Bonds will be a beneficiary under the Indenture, as supplemented by the applicable Supplemental Indenture;

(iii) 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 as amended or supplemented or with respect to any Form T-1. For purposes of this paragraph (in each case, excluding the documents incorporated by reference therein), such counsel has assumed that the statements made and incorporated by reference in the Registration Statement and the Prospectus are correct and complete; and

(iv) 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 filed in accordance with Rules 424(b) and 430B under the Act.

In addition, such counsel shall provide a statement to the effect that such counsel has participated in telephone conferences with officers and other representatives of 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:

(v) the Registration Statement, at 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;

(vi) 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

(vii) 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 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 of the Pricing Agreement for such Designated Bonds at a time prior to the execution of the Pricing Agreement with respect to such Designated Bonds, and at the Time of Delivery for such Designated Bonds, the Company’s independent registered public accounting firm that has certified the consolidated financial statements of the Company and its subsidiaries included or incorporated by reference in the Registration Statement shall have furnished to the Representatives a letter, dated the date of the Pricing Agreement, 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 such Time of Delivery reaffirming the statements made in their letter dated the date of the Pricing Agreement, except that the specified date referred to in such letter delivered on such 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 such 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 of the Pricing Agreement relating to the Designated Bonds 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 Prospectus as amended prior to the date of the Pricing Agreement relating to the Designated Bonds, and (ii) since the respective dates as of which information is given in the Prospectus as amended prior to the date of the Pricing Agreement relating to the Designated Bonds 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, consolidated financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole, otherwise than as set forth or contemplated in the Prospectus as amended prior to the date of the Pricing Agreement relating to the Designated Bonds, 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 Designated Bonds on the terms and in the manner contemplated in the Prospectus as first amended or supplemented relating to the Designated Bonds;

(g) At or after the Applicable Time relating to the Designated Bonds (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, other than a downgrade by Fitch Ratings to not lower than A+, and (ii) no such organization, other than Fitch Ratings, 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 of the Pricing Agreement relating to the Designated Bonds 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 Designated Bonds on the terms

and in the manner contemplated in the Prospectus as first amended or supplemented relating to the Designated Bonds;

(i) The Company shall have complied with the provisions of Section 5(c) hereof with respect to the furnishing of prospectuses on the New York business day next succeeding the date of any Pricing Agreement for such Designated Bonds; and

(j) The Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery for the Designated Bonds 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 such Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such 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 any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the First Mortgage 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 any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the First Mortgage Bonds or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Underwriter of Designated Bonds through the Representatives expressly for use in the Prospectus as amended or supplemented relating to such Designated Bonds.

(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 any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the First Mortgage 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 any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus as amended or supplemented or any other prospectus relating to the First Mortgage 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 of the Designated Bonds on the other from the offering of the First Mortgage Bonds to which such loss, claim, damage or liability (or action in respect thereof) relates. 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 of the Designated Bonds 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 such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such 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 such 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 Designated 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 of Designated Bonds in this subsection (d) to contribute are several in proportion to their

respective underwriting obligations with respect to such First Mortgage 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 Designated Bonds which it has agreed to purchase under the Pricing Agreement relating to such Designated Bonds, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Designated 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 Designated 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 Designated 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 Designated Bonds, or the Company notifies the Representatives that it has so arranged for the purchase of such Designated Bonds, the Representatives or the Company shall have the right to postpone the Time of Delivery for such Designated Bonds 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 the Pricing Agreement with respect to such Designated Bonds.

(b) If, after giving effect to any arrangements for the purchase of the Designated Bonds of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Designated Bonds which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Designated Bonds, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Designated Bonds which such Underwriter agreed to purchase under the Pricing Agreement relating to such Designated Bonds and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Designated Bonds which such Underwriter agreed to purchase under such Pricing Agreement) of the Designated 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 Designated Bonds of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Designated Bonds which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Designated 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 Designated Bonds of a defaulting Underwriter or Underwriters, then the Pricing Agreement relating to such Designated Bonds 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 First Mortgage Bonds.

11. If any Pricing Agreement shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Designated Bonds covered by such Pricing Agreement except as provided in Sections 6 and 8 hereof; but, if for any other reason Designated Bonds are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Designated Bonds, but the Company shall then be under no further liability to any Underwriter with respect to such Designated Bonds except as provided in Sections 6 and 8 hereof.

12. In all dealings hereunder, the Representatives of the Underwriters of Designated Bonds shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in the Pricing Agreement.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the address of the Representatives as set forth in the Pricing Agreement; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by the

Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. This Agreement and each Pricing Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 8 and 10 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement or any such Pricing Agreement. No purchaser of any of the First Mortgage Bonds from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

14. The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Designated Bonds contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither the Representatives nor any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making their 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.
