(a) To prepare the Prospectus, as amended or supplemented, in a form approved by the Representatives and to file such Prospectus pursuant to Rule 424(b) under the Act not later than the Commission’s close of business on the second business day following the date hereof or, if applicable, such earlier time as may be required by Rule 424(b); to make no further amendment or any supplement to the Registration Statement or Prospectus, as amended or supplemented, after the date hereof and on or prior to the Time of Delivery which shall be reasonably disapproved by the Representatives promptly after reasonable notice thereof; to advise the Representatives promptly of any such amendment or supplement after the Time of Delivery and furnish the Representatives with copies thereof; to file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as the delivery of a prospectus is required in connection with the offering or sale of the Bonds, and during such same period to advise the Representatives, promptly after it receives notice thereof, of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Prospectus or any amended Prospectus has been filed with the Commission, of the issuance by the Commission of any stop order or of any order preventing or suspending the use of any prospectus relating to the Bonds, of the suspension of the qualification of the Bonds for offering or sale in any jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any examination pursuant to Section 8(e) of the Act concerning the Registration Statement, or of the Company becoming the subject of a proceeding under Section 8A of the Act in connection with the offering of the Bonds, or of any request by the Commission for the

11

amending or supplementing of the Registration Statement or Prospectus or for additional information; and, in the event of the issuance of any such stop order or of any such order preventing or suspending the use of any prospectus relating to the Bonds or suspending any such qualification, to promptly use reasonable best efforts to obtain the withdrawal of such order;

(b) To prepare a final term sheet or sheets, as the case may be (in either such case, the “Final Term Sheet”) reflecting the final terms of the Bonds, in the form of Schedule III hereto (except that the Final Term Sheet may also include information regarding the credit ratings of the Bonds and such other information as the Company and the Representatives may agree), and file such Final 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; provided that the Company shall furnish the Representatives with copies of such Final Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonably object;

(c) If at any time after the date hereof any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the Preliminary Prospectus 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 the light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify the Representatives and, upon their request, to file such document and to prepare and furnish without charge to each Underwriter as many copies as the Representatives may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance;

(d) Promptly from time to time to take such action as the Representatives may reasonably request to qualify the Bonds for offering and sale under the securities laws of such domestic jurisdictions and (with the prior consent of the Company) foreign jurisdictions as the Representatives may request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Bonds, provided that in connection therewith the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction;

(e) Prior to 10:00 a.m., New York City time, on the second business day succeeding the date hereof, or such later time or date as agreed to by the Company and the Representatives, and from time to time, to furnish the Underwriters with copies of the Prospectus in New York City, as amended or supplemented, in such quantities as the Representatives may reasonably request, and, if the delivery of a prospectus is required at any time in connection with the offering or sale of the Bonds and if at such time any event shall have occurred as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any

12

material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made when such Prospectus is delivered, not misleading, or, if for any other reason it shall be necessary during such same period to amend or supplement the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus in order to comply with the Act, the Exchange Act or the Trust Indenture Act, to notify the Representatives and upon their request to file such document and to prepare and furnish without charge to each Underwriter and to any securities dealer participating in the offering of the Bonds as many copies as the Representatives may from time to time reasonably request of an amended Prospectus or a supplement to the Prospectus which will correct such statement or omission or effect such compliance;

(f) To make generally available to its securityholders as soon as practicable, but in any event not later than fifteen months after the date hereof, an earnings statement of the Company and its consolidated subsidiaries (which need not be audited) complying with Section 11(a) of the Act and the Rules and Regulations (including, at the option of the Company, Rule 158);

(g) During the period beginning from the date hereof and continuing to and including the later of (i) the termination of trading restrictions for the Bonds, as notified to the Company by the Representatives, but only if the Representatives shall have notified the Company in writing at the Time of Delivery that such trading restrictions have not been terminated, and (ii) the Time of Delivery, not to offer, sell, contract to sell or otherwise dispose of any First Mortgage Bonds, without the prior written consent of the Representatives;

(h) Immediately following the execution of this Agreement, the Company will prepare a prospectus supplement, dated the date hereof (the “Prospectus Supplement”), containing the terms of the Bonds, the plan of distribution thereof and such other information as may be required by the Act or the Rules and Regulations or as the Representatives and the Company deem appropriate, and will file or transmit for filing with the Commission in accordance with Rule 424(b) of the Rules and Regulations copies of the Prospectus (including such Prospectus Supplement);

(i) To apply the net proceeds from the sale of the Bonds as set forth in the Prospectus;

(j) If the Company elects to rely upon Rule 462(b), the Company shall file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) by 10:00 P.M., Washington, D.C. time, on the date of this Agreement, and the Company shall at the time of filing pay to the Commission the filing fee for the Rule 462(b) Registration Statement;

(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,

13

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 Final Term Sheet and any other 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 or otherwise permitted by the immediately preceding sentence is hereinafter referred to as a “Permitted Free Writing Prospectus.” For purposes of clarity, it is understood and agreed that the term Issuer Free Writing Prospectus, as used in this Agreement, includes all Permitted Free Writing Prospectuses; and

(l) As promptly as practicable after the Time of Delivery, the Company will duly record the Current Supplemental Indenture in all offices of county recorders and clerks of all counties in the States of California, Arizona and Nevada in which any real property subject to the lien of the Indenture is located.

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 Memoranda; (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, Inc. 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.

14

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 from 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) The Company’s general counsel, or any associate or assistant general counsel of the Company, shall have furnished to the Representatives a written opinion, dated the Time of Delivery, in the form previously agreed and satisfactory to the Representatives.

(d) Latham & Watkins LLP shall have furnished to the Representatives their written opinion or opinions and negative assurances letter, dated the Time of Delivery, in the forms previously agreed and satisfactory to the Representatives.

(e) Deloitte & Touche LLP shall have furnished to the Representatives, on the date hereof at a time prior to the execution of this Agreement, 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, at the Time of Delivery, 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 material loss or interference with its business from fire, explosion, flood or other calamity, whether or not

15

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 material change in the capital stock or long-term debt of the Company or any of its subsidiaries or any material adverse change, or any development involving a prospective material adverse change, in or affecting the general affairs, management or consolidated financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole, in each case 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 securities by any “nationally recognized statistical rating organization,” as that term is defined by the Commission for purposes of Section 3(a)(62) under the Exchange 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 securities.

(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 or the Nasdaq Global Market; (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 (A) is material and adverse and (B) 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 second business day 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

16

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 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 or any other prospectus relating to the Bonds or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.

(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 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 or any other prospectus relating to the Bonds or any such amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information consists of the following: the information in the third paragraph of text under the caption “Underwriting (Conflicts of Interest)” in the Preliminary Prospectus and the Prospectus concerning the terms of the offering by the Underwriters; and the information in the third sentence of the fourth paragraph of text, and the fifth, sixth, seventh and eighth paragraphs of text (solely with respect to the statements attributable to the Underwriters) under the caption “Underwriting (Conflicts of Interest)” in the Preliminary Prospectus

17

and the Prospectus, insofar as such information relates to market making, stabilization, penalty bids, overallotment, short positions and purchases to cover short positions by the Underwriters; 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 indemnifying 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 directors, officers, employees, agents 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 directors, officers, employees, agents and controlling persons that are different from or additional to those available to the Company and its officers, directors, employees and controlling persons, and the fees and expenses of a single separate counsel for the Underwriters and their respective directors, officers, employees, agents and controlling persons (in addition to local counsel) shall be paid by the Company. The indemnifying party shall not be liable for any settlement or compromise of, or the consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification may be sought hereunder effected without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), but, if settled or compromised with the indemnifying party’s consent, or if judgment shall be entered following consent to the entry of such judgment given with the indemnifying party’s consent, or if there shall otherwise be a final judgment for the plaintiff, the indemnifying party agrees to indemnify and hold harmless each indemnified party against any and all losses, claims, damages, liabilities and expenses, joint or several, by reason of such settlement, compromise or judgment, as the case may be. No indemnifying party shall, without the written consent of the indemnified party (which consent shall not be unreasonably withheld), effect the settlement or compromise of, or consent to the entry of

18

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 in each case 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 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

19

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 director, officer, employee and agent of any Underwriter and 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, director and employee 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 reasonably 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.

20

(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. If this 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 Bonds except as provided in Sections 6 and 8 hereof; but, if for any other reason 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 the Bonds, but the Company shall then be under no further liability to any Underwriter with respect to the Bonds except as provided in Sections 6 and 8 hereof.

12. In all dealings hereunder, the Representatives of the Underwriters 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 this Agreement.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, overnight courier or facsimile transmission to BNP Paribas Securities Corp., 787 Seventh Avenue, New York, New York 10019, Attention: Syndicate Desk—7th Floor, facsimile: (917) 472-4745; Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York 10013, Attention: General Counsel, facsimile: (646) 291-1469; Deutsche Bank Securities Inc., 60 Wall Street, 2nd Floor, New York, New York 10005, Attention: Debt Capital Markets, facsimile: (212) 797-2202, with a copy to General Counsel, facsimile: (646) 374-1071; and Mizuho Securities USA LLC, 320 Park Avenue, 12th Floor, New York, New York 10022, Attention: Debt Capital Markets, facsimile: (212) 205-7812; and if to the Company shall be delivered or sent by mail, overnight courier or facsimile

21

transmission to the address of the Company set forth on the cover page of the Registration Statement, Attention: Secretary, with a copy to the General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail, overnight courier or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or email or facsimile transmission 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.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

13. This 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 directors, officers, employees and agents of each Underwriter, the officers, directors and employees 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. No purchaser of any of the Bonds from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

In addition, May 31, 2019 shall be an interest payment date for the Series TTT Bonds for purposes of Section 9 of Article II of the Indenture, provided that no interest shall be payable on such date. The principal and premium, if any, and interest on the Series TTT Bonds shall be payable at the office or agency maintained by the Company for such purpose (initially the corporate trust office of the Trustee) in the City and County of Los Angeles, State of California and, if Series TTT Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of this Article I, at the office or agency maintained by the Company for such purpose in the Borough of Manhattan, City and County of New York, State of New York. The Series TTT Bonds shall be dated as in Section 9 of Article II of the Indenture provided with respect to registered bonds without coupons.

The Series TTT Bonds shall further be redeemable, exchangeable, transferable and otherwise have the terms set forth in the Form of Bond.

The Series TTT Bonds shall otherwise be of such terms, provisions, tenor and form as provided in this Sixty-Eighth Supplemental Indenture.

Section 2: The Series TTT Bonds shall be executed, authenticated and delivered in accordance with the provisions and shall be entitled to the protection and security of the Original Indenture, as supplemented by this Sixty-Eighth Supplemental Indenture and the other supplemental indentures, and shall be subject to all of the terms, conditions and covenants and limitations thereof. The aggregate principal amount of the Series TTT Bonds, which may be executed by the Company and authenticated and delivered by the Trustee and secured by the Indenture as from time to time in effect, is limited only to the extent provided in Section 1 of Article II of the Original Indenture. The Company has authorized the issuance and sale on the date hereof of $400,000,000 aggregate principal amount of Series TTT Bonds. The Company may, from time to time, without notice to or the consent of the registered holders of the Series TTT Bonds but upon and subject to the terms and provisions of the Indenture, increase the principal amount of the Series TTT Bonds under the Indenture and issue such increased principal amount, or any portion thereof. Any additional Series TTT Bonds so issued shall have the same form and terms (other than offering price, the date of original issuance and, under certain circumstances, the date from which interest thereon shall begin to accrue and the first Interest Payment Date (as defined below)) as the Series TTT Bonds previously issued and shall form a single series of bonds under the Indenture with the previously issued Series TTT Bonds.

Section 3: The Series TTT Bonds shall be issued only as fully registered bonds without coupons. The fully registered bonds without coupons and the certificate of authentication to be endorsed on all Series TTT Bonds shall be substantially in the form set forth on the Form of Bond. In addition, the Series TTT Bonds may be issuable in whole or in part in the form of one or more securities that evidence all or part of the bonds of such series and are registered in the name of a depositary (as defined below) or a nominee thereof for such series (each, a “Global Security”) and, in such case, the Board of Directors of the Company (or an authorized officer designated by the Board of Directors of the Company) shall appoint a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), designated to act as depositary (a “depositary”) for such Global Securities; the initial depositary so appointed is The Depository Trust Company. The definitive Series TTT Bonds shall be numbered in such manner as the Company shall at any time or from time to time determine.

Section 4: In the event Series TTT Bonds are issued as Global Securities the following provisions, in addition to the provisions of the Indenture, shall apply:

(1) Each Global Security authenticated under the Indenture shall be registered in the name of the depositary designated for such Global Security or a nominee thereof and delivered to such depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Series TTT Bond for all purposes of this Supplemental Indenture.

(2) Notwithstanding any other provision in this Supplemental Indenture, no Global Security may be exchanged in whole or in part for Series TTT Bonds registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any person other than the depositary for such Global Security or a nominee thereof unless (A) such depositary has notified the Company that it is unwilling or unable to continue as depositary for the Global Security or Global Securities, as the case may be, representing the Series TTT Bonds and a

11

successor depositary has not been appointed by the Company within 90 days of receipt by the Company of such notification, (B) if at any time the depositary ceases to be a clearing agency registered under the Exchange Act at a time when the depositary is required to be so registered to act as such depositary and no successor depositary shall have been appointed by the Company within 90 days after it became aware of the depositary’s ceasing to be so registered, (C) the Company, in its sole discretion, executes and delivers to the Trustee a written order signed in the name of the Company by its Chairman of the Board, its President or a Vice President, and by its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary to the effect that the Global Securities of such series shall be exchangeable as described below, or (D) a “completed default” (as defined in the Indenture) has occurred and is continuing with respect to the Series TTT Bonds. If any of the events described in clauses (A) through (D) of the preceding sentence occur, the beneficial owners of interests in such Global Securities will be entitled to exchange those interests for definitive Series TTT Bonds and, without unnecessary delay but in any event not later than the earliest date on which those interests may be so exchanged, the Company will prepare and deliver to the Trustee definitive Series TTT Bonds in such form and denominations as are required by or pursuant to the Indenture, and in an aggregate principal amount equal to the aggregate principal amount of such Global Securities, such bonds to be duly executed by the Company. On or after the earliest date on which such beneficial interests may be so exchanged, such Global Securities shall be surrendered from time to time by the depositary as shall be specified in the order from the Company with respect thereto (which the Company agrees to deliver) to the Trustee, as the Company’s agent for such purpose, and in accordance with any instructions given to the Trustee and the depositary by the Company (which instructions shall be in writing but need not be contained in or accompanied by an officers’ certificate or be accompanied by an opinion of counsel), to be exchanged, in whole or in part, for definitive Series TTT Bonds as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of each surrendered Global Security, a like aggregate principal amount of definitive Series TTT Bonds of authorized denominations as the portion of such Global Security to be exchanged. Promptly following any such exchange in part, such Global Security shall be returned by the Trustee to such depositary or its custodian. If a definitive Series TTT Bond is issued in exchange for any portion of a Global Security after the close of business at the place where such exchange occurs on or after (i) any regular record date for a regularly scheduled interest payment date (an “Interest Payment Date”) for such bond and before the opening of business at that place of exchange on such Interest Payment Date, or (ii) any special record date for the payment of interest for such bond which was not punctually paid or duly provided for on any Interest Payment Date (“Defaulted Interest”) and before the opening of business at such place of exchange on the related proposed date for the payment of such Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such definitive bond, but shall be payable on the Interest Payment Date or proposed date for payment, as the case may be, only to the person to whom interest in respect of such portion of such Global Security shall be payable in accordance with the provisions of the Indenture and the Series TTT Bonds.

(3) Subject to Clause (2) above, any exchange or transfer of a Global Security for other Series TTT Bonds may be made in whole or in part, and all definitive Series TTT Bonds issued in exchange for or upon transfer of a Global Security or any portion thereof shall be registered in such names as the depositary for such Global Security shall direct.

(4) Every Series TTT Bond authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such bond is registered in the name of a person other than the depositary for such Global Security or a nominee thereof.

(5) Unless otherwise specified as contemplated by Section 1 of Article I of this Supplemental Indenture for the Series TTT Bonds evidenced thereby, every Global Security authenticated and delivered hereunder shall bear a legend in substantially the following form:

THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. ANY TRANSFER, PLEDGE, OR OTHER

12

USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY OTHER PERSON IS WRONGFUL, INASMUCH AS THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN.

Section 5: The Series TTT Bonds may contain or have imprinted thereon such provisions or specifications not inconsistent with the Indenture as may be required to comply with the rules of any stock exchange or any federal or state authority or commission, or to comply with usage with respect thereto, and may bear such other appropriate endorsements or notations as are authorized or permitted by the Indenture.

Section 6: In the manner and subject to certain conditions and limitations specified herein and in the Indenture, Series TTT Bonds may be exchanged without a service charge for a like aggregate principal amount of such Series TTT Bonds of other authorized denomination or denominations; provided that the Company may require payment of a sum or sums sufficient to reimburse it for any stamp tax or other governmental charge payable in connection therewith.

Section 7: The Company shall maintain in the City and County of Los Angeles, State of California, and in such other place or places as the Company may designate at any time or from time to time, an office or agency where Series TTT Bonds, including Series TTT Bonds issued in definitive certificated form, may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture. Without limitation to the foregoing, if Series TTT Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of this Article I, the Company shall also maintain in the Borough of Manhattan, City and County of New York, State of New York, an office or agency where Series TTT Bonds, including Series TTT Bonds issued in definitive certificated form, may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture. Such office or agency in the City and County of Los Angeles, State of California, and any such office or agency in the Borough of Manhattan, City and County of New York, State of New York, shall be a corporate trust office of the Trustee unless and until the Company shall designate another office or agency by notice in writing delivered to the Trustee.

Section 8: No transfer or exchange of any Series TTT Bonds pursuant to any of the provisions of this Article I shall be made except upon and in accordance with all of the applicable terms, provisions and conditions of said bonds and of the Indenture.

[REVERSE SIDE OF 4.100% FIRST MORTGAGE BOND, SERIES TTT, DUE 2049]

This bond is one of a duly authorized issue of bonds of the Company, known as its First Mortgage Bonds, of the series and designation indicated on the face hereof (the “Series TTT Bonds”), all issued and to be issued under and equally secured by a Mortgage and Deed of Trust dated July 1, 1940, and indentures supplemental thereto, including the Sixty-Eighth Supplemental Indenture (the “Sixty-Eighth Supplemental Indenture”) dated as of May 31, 2019 (which Mortgage and Deed of Trust, as so amended and supplemented and as the same may be further amended or supplemented from time to time, is herein called the “Indenture”), executed by the Company to U.S. Bank National Association, as successor trustee (herein called, together with its successors in such capacity, the “Trustee”), to which Indenture reference is hereby made for a description of the property mortgaged, pledged, hypothecated and in which a security interest was granted, the nature and extent of the security, the rights of the holders of the Series TTT Bonds as to such security, and the terms and conditions upon which the Series TTT Bonds may be issued under the Indenture and are secured. The principal hereof may be declared or may become due on the conditions, in the manner and at the time set forth in the Indenture, upon the happening of a completed default (as defined in the Indenture) as in the Indenture provided. This Series TTT Bond is one of a series of Series TTT Bonds and is sometimes referred to as “this bond.”

Interest on the Series TTT Bonds will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

With the consent of the Company and to the extent permitted by and as provided in the Indenture, the rights and obligations of the Company or of the holders of the Series TTT Bonds, or the terms and provisions of the Indenture or of any indentures supplemental thereto, may be modified or altered by the affirmative vote of the holders of the percentage of principal amount of bonds required by the Indenture; provided, however, that without the consent of the holder hereof no such modification or alteration shall permit, among other things, the reduction of the principal or premium, if any, or the extension of the maturity of the principal of this bond, or the reduction of the rate of interest hereon, or any other modification of the terms of payment of such principal or premium, if any, or interest.

The Company, the Trustee, any paying agent, any registrar, and any depositary may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest hereon and for all other purposes and shall not be affected by any notice to the contrary.

Prior to December 15, 2048 (the “Par Call Date”), the Company may at the Company’s option redeem the Series TTT Bonds, at any time in whole or from time to time in part, at a redemption price (the “Redemption Price”) for any redemption date (a “Redemption Date”) equal to the greater of the following amounts: (a) 100% of the principal amount of the Series TTT Bonds being redeemed on that Redemption Date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Series TTT Bonds being redeemed on that Redemption Date (not including any portion of any payments of accrued and unpaid interest to that Redemption Date) that would be due if the Series TTT Bonds matured, and accrued and unpaid interest was payable, on the Par Call Date, discounted to that Redemption Date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 25 basis points, as determined by the Independent Investment Banker (as defined below), plus, in each case, accrued and unpaid interest on the Series TTT Bonds being redeemed to that Redemption Date. On and after the Par Call Date, the Company may at the Company’s option redeem the Series TTT Bonds, at any time in whole or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Series TTT Bonds being redeemed, plus accrued and unpaid interest on the Series TTT Bonds being redeemed to the Redemption Date. Notwithstanding the foregoing, installments of interest on Series TTT Bonds that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date will be payable on that Interest Payment Date to the registered holders of such Series TTT Bonds as of the close of business on the relevant record date according to the terms of the Series TTT Bonds and the Indenture. The Redemption Price will, if applicable, be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Notice of any redemption will be mailed at least 30 days, but not more than 60 days, before the Redemption Date to each registered holder of the Series TTT Bonds to be redeemed. Once notice of redemption is mailed, the

A-3

Series TTT Bonds called for redemption will become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest to the Redemption Date, provided that the Company may rescind any notice of redemption by notice given not less than five days prior to the proposed Redemption Date. Redemption will not be conditional upon receipt by the Trustee of monies sufficient to pay the Redemption Price.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Series TTT Bonds or portions thereof called for redemption. The Company will pay the Redemption Price and any accrued interest once the Series TTT Bonds are surrendered for redemption. If only a portion of any Series TTT Bonds is redeemed, the Trustee will deliver new Series TTT Bonds for the remaining portion without charge.

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

“Comparable Treasury Issue” means, with respect to any Redemption Date, the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Series TTT Bonds to be redeemed on such Redemption Date (assuming the Series TTT Bonds matured on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Series TTT Bonds (assuming the Series TTT Bonds matured on the Par Call Date).

“Comparable Treasury Price” means, with respect to any Redemption Date, (A) the average of the Reference Treasury Dealer Quotations for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means, with respect to any Redemption Date, one of the Reference Treasury Dealers appointed by the Company to act as the “Independent Investment Banker.”

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third business day preceding such Redemption Date. As used in the preceding sentence, “business day” means any day (other than a Saturday or Sunday) on which banking institutions in The City of New York are not authorized or obligated by law or executive order to remain closed.

“Reference Treasury Dealers” means, with respect to any Redemption Date, (A) BNP Paribas Securities Corp., Citigroup Global Markets Inc., Deutsche Bank Securities Inc. and Mizuho Securities USA LLC (or their respective affiliates which are Primary Treasury Dealers (as defined below)), and their respective successors, provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company.

In the event that the Company elects to redeem only a portion of the outstanding Series TTT Bonds, (a) the Series TTT Bonds to be redeemed shall be selected as provided in the Indenture and, in the case of Series TTT Bonds represented by a Global Security (as defined in the Sixty-Eighth Supplemental Indenture), in accordance with the procedures of The Depository Trust Company (or its successor as depositary) and (b) in the case of any Series TTT Bond being redeemed in part, the principal amount redeemed must be $1,000 or an integral multiple of $1,000 and the remaining principal amount must be an authorized denomination.

As more fully provided in and subject to the provisions of the Indenture, the Series TTT Bonds are also subject to redemption on any date, under certain circumstances specified in the second paragraph of Section 13 of Article XI of the Indenture in case of the disposition or taking (among other things) of certain properties of the

A-4

Company, at 100% of the principal amount thereof, together with accrued interest on the Series TTT bonds being redeemed to the date of redemption.

This bond is transferable as prescribed in the Indenture by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency maintained by the Company for that purpose (initially the corporate trust office of the Trustee) in the City and County of Los Angeles, State of California, and, if Series TTT Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of Article I of the Sixty-Eighth Supplemental Indenture, at the office or agency maintained by the Company for such purpose in the Borough of Manhattan, City and County of New York, State of New York, upon surrender and cancellation of this bond and thereupon a new registered bond or bonds of the same series of authorized denominations and of a like aggregate principal amount, will be issued to the transferee in exchange herefor as provided in the Indenture, upon payment of any tax or taxes or other governmental charges required to be paid by the Company by reason of such transfer.

The registered owner of any Series TTT Bond, at the option of such holder, may surrender the same, accompanied by a written instrument of transfer in form approved by the Company duly executed by the registered owner, at the office or agency maintained by the Company for that purpose (initially the corporate trust office of the Trustee) in the City and County of Los Angeles, State of California and, if Series TTT Bonds are issued in definitive certificated form under the circumstances set forth in clause (2) of Section 4 of Article I of the Sixty-Eighth Supplemental Indenture, at the office or agency maintained by the Company for such purpose in the Borough of Manhattan, City and County of New York, State of New York, for cancellation in exchange for another or other registered bonds of the said series of higher or lower authorized denominations of an aggregate principal amount equal to the aggregate principal amount of the bond or bonds so surrendered and bearing interest as provided in Section 9 of Article II of the Indenture, and upon payment of any tax or taxes or other governmental charges required to be paid by the Company by reason of such exchange and subject to the terms and conditions specified in the Indenture, and thereupon the Company shall execute and deliver to the Trustee and the Trustee shall authenticate and deliver such other bonds to such registered owner at its office or at such office or agency of the Company, at the option of such registered owner.

No recourse shall be had for the payment of the principal of (or premium, if any) or the interest on this bond, or any part thereof, or of any claim based hereon or in respect hereof or of said Indenture, against any incorporator, or any past or future stockholder, officer or director, as such, of the Company or of any predecessor or successor corporation, either directly or through the Company, or through any such predecessor or successor corporation, or through any receiver or a trustee in bankruptcy, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released, as more fully provided in the Indenture.

This Series TTT Bond shall be governed by and construed in accordance with the laws of the State of California, without regard (to the extent permitted by applicable law) to conflicts of laws principles thereof.

Ladies and Gentlemen:

We have acted as special counsel to San Diego Gas & Electric Company, a California corporation (the “Company”), in connection with the Company’s issuance of $400,000,000 aggregate principal amount of 4.100% First Mortgage Bonds, Series TTT, due 2049 (the “Bonds”) under an indenture, dated as of July 1, 1940, between the Company and U.S. Bank National Association, as successor trustee (the “Trustee”), as amended and supplemented to date, including as supplemented by the Sixty-Eighth Supplemental Indenture, dated May 31, 2019 (the “Indenture”), between the Company and the Trustee, setting forth the terms of the Bonds, and pursuant to a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission (the “Commission”) on January 22, 2018 (Registration No. 333-222650) (the “Registration Statement”), and an underwriting agreement, dated May 28, 2019, between the underwriters named therein and the Company.

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus, other than as expressly stated herein with respect to the issue of the Bonds.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We are opining herein as to the internal laws of the State of California and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction, or as to any matters of municipal law or the laws of any local agencies within any state.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof, the Bonds have been duly authorized by all necessary corporate action of the Company and are the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

Our opinion is subject to: (i) the effects of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights or remedies of creditors; (ii) the effects of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith, fair dealing and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions for the indemnification or exculpation of, or contribution to, a party with respect to a liability where such indemnification, exculpation or contribution is contrary to public policy; and (iv) we express no opinion with respect to (a) consents to, or restrictions upon, governing law, jurisdiction, venue, service of process, arbitration, remedies or judicial relief; (b) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights; (c) waivers of rights or defenses contained in Section 9.08 of the Indenture; and waivers of broadly or vaguely stated rights; (d) provisions for exclusivity, election or cumulation of rights or remedies; (e) provisions authorizing or validating conclusive or discretionary determinations; (f) provisions for the payment of attorneys’ fees where such payment is contrary to law or public policy and we call to your attention the provisions of Sections 1717 and 1717.5 of the California Civil Code, which limit and create obligations for the payment of attorneys’ fees; (g) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any agreement, right or property, or the effect thereon of California Civil Code Section 711; (h) provisions for liquidated damages, default interest, late charges, monetary penalties, prepayment or make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty; (i) provisions permitting, upon acceleration of any indebtedness (including the Bonds), collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon; and (j) the severability, if invalid, of provisions to the foregoing effect. We do not render any opinion herein with respect to the creation, validity, perfection or priority of any security interest.

With your consent, except to the extent we have expressly opined as to such matters with respect to the Company herein we have assumed (a) that the Indenture and the Bonds (collectively, the “Documents”) have been duly authorized, executed and delivered by the parties thereto, (b) that the Documents constitute legally valid and binding obligations of the parties thereto, enforceable against each of them in accordance with their respective terms, and (c) that

the status of the Documents as legally valid and binding obligations of the parties is not affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities.

This opinion is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. We consent to your filing this opinion as an exhibit to the Company’s Form 8-K dated May 31, 2019 and to the reference to our firm contained in the prospectus for the offering of the Bonds under the heading “Legal Matters.” In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.
