Neither the Company nor any affiliate of the Company has taken, nor will the Company or any such affiliate take, directly or indirectly, any action which is designed, or would reasonably be expected, to cause or result in, or which constitutes, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of any Shares or to result in a violation of Regulation M under the Exchange Act.

(xxix)Actively-Traded Security. The Common Stock is an “actively traded security” exempted from the requirements of Rule 101 of Regulation M under the Exchange Act by subsection (c)(1) of such rule.

Any certificate signed by any officer or other authorized signatory of the Company and delivered to the Agents or to counsel for the Agents pursuant to this Agreement or any Confirmation shall be deemed a representation and warranty by the Company to the Agents as to the matters covered thereby, and the officer(s) or other authorized signatory(ies) signing such certificate shall have no personal liability for any representation or warranty made.

Section 2. Sale and Delivery of Shares.

(a)Subject to the terms and conditions set forth herein, the Company agrees to (i) issue and sell Shares through the applicable Agent acting as sales agent of the Company or directly to the applicable Agent or Agents acting as principal(s) from time to time or (ii) enter into a Confirmation with any Forward Purchaser and, in consultation with such Forward Purchaser and the applicable Agent (which shall be an affiliate of such Forward Purchaser), instruct such Agent, acting as forward seller on behalf of such Forward Purchaser, to offer and sell the Shares borrowed by such Forward Purchaser from third parties as contemplated by such Confirmation. Sales of the Shares, if any, through an Agent acting as sales agent of the Company or directly to an Agent acting as principal or as forward seller on behalf of any Forward Purchaser will be made in (1) negotiated transactions, which may include block trades, as the Company and such Agent may agree or (2) “at the market” offerings (as defined in Rule 415

under the Securities Act Regulations) by means of ordinary brokers’ transactions at market prices prevailing at the time of sale, including sales made directly on the NYSE, sales made to or through market makers and sales made through other securities exchanges or electronic communications networks or by any other method permitted by applicable law as otherwise agreed between the applicable Agent and the Company. Sales of Shares, if any, purchased by an Agent as principal will be made as provided in the applicable Terms Agreement and the applicable pricing supplement prepared in connection with the offering of those Shares.

(b)The Shares to be sold to an Agent as sales agent of the Company or as forward seller are to be sold on any day (other than a day on which the NYSE is closed)(each, a “Trading Day”) on which (i) the Company has instructed such Agent, as sales agent of the Company or as forward seller, to make such sales, (ii) the Company has satisfied its covenants and conditions specified in Sections 4 and 5 hereof, (iii) the respective Agent has agreed to act as Agent with respect to such sales and (iv) if such Shares are to be sold by such Agent as forward seller, the Company shall have entered into a Confirmation with the applicable Forward Purchaser. On any Trading Day, the Company may sell Shares through only one Agent and, if it determines to do so, shall instruct the applicable Agent by telephone (confirmed promptly by telecopy or email, which confirmation will be promptly acknowledged by such Agent and any applicable Forward Purchaser) as to the maximum number of Shares to be sold on such Trading Day and the minimum price per Share at which such Shares may be sold. Such instruction shall also specify whether such Shares will be borrowed by a Forward Purchaser and sold through the applicable Agent, as forward seller, in connection with hedging a forward stock purchase transaction pursuant to a Confirmation in accordance with clause (ii) of the paragraph above. Subject to the terms and conditions specified herein (including, without limitation, the accuracy of the representations and warranties of the Company and the performance by the Company of its covenants and other obligations contained herein and the satisfaction of the additional conditions specified in Section 5 hereof), such Agent shall use its commercially reasonable efforts, consistent with its normal trading and sales practices and applicable law and regulations, to sell all of the Shares so designated by the Company as sales agent in accordance with such instruction. On any Trading Day, the Company shall give at least one business day’s prior written notice by telecopy or email to the applicable Agents or Forward Purchasers as to any change of the Agent or Forward Purchaser through whom sales of Shares as sales agent of the Company or as forward seller will be made. For the avoidance of doubt, the foregoing limitation on sales through only one Agent per Trading Day shall not apply to sales solely to employees or security holders of the Company or its subsidiaries or to a trustee or other person acquiring shares of the Company’s Common Stock for the accounts of such persons in which either Barclays, BofAS, Citigroup, Goldman, JPM, Mizuho, MS, MUFG, RBC, Scotia or WFS is acting for the Company in a capacity other than as Agent or Forward Purchaser under this Agreement. The Company, Agents and Forward Purchasers each acknowledge and agree that (A) there can be no assurance that any Agent will be successful in selling any Shares, (B) the Agents (whether acting on behalf of the Company or as forward seller on behalf of the related Forward Purchaser) will not incur any liability or obligation to the Company if they fail to sell Shares for any reason other than a failure to use their respective commercially reasonable efforts, consistent with their respective normal trading and sales practices and applicable law and regulations, to sell such Shares as required by this Agreement and (C) no Agent or Forward Purchaser shall incur any liability for not borrowing, offering or selling any Shares as a result of the circumstances set forth in clause (i) or (ii) of Section 2(l).

(c)The Company or the Agent through whom the sale of Shares are to be made as sales agent of the Company or as forward seller on any Trading Day may, upon notice to the applicable Agent or the Company, respectively, by telephone (confirmed promptly by telecopy or email, which confirmation will be promptly acknowledged by the receiving party), suspend the offering of Shares with respect to which such Agent is acting as sales agent of the Company or as forward seller for any reason and at any time; provided, however, that such suspension shall not affect or impair such parties’ respective obligations with respect to the Shares sold, or with respect to Shares that the Company has agreed to sell, hereunder prior to the giving of such notice (provided that, for the avoidance of doubt, the Company shall be able to specify or modify the Hedge Completion Date (as defined in the Confirmations) pursuant to any Confirmation in its discretion as provided therein).

(d)The gross sales price of any Shares sold pursuant to this Agreement by the applicable Agent acting as sales agent shall be equal to, in the discretion of such Agent but subject to the specific instructions of the Company, the market price prevailing at the time of sale for the Shares sold by such Agent on the NYSE or otherwise, at prices related to prevailing market prices or at negotiated prices. The compensation payable to an

Agent for sales of Shares with respect to which such Agent acts as sales agent shall be at a mutually agreed upon rate, not to exceed 1.0% of the gross sales price for such Shares. With respect to sales of Shares by an Agent as sales agent of the Company, the remaining proceeds, after further deduction for any transaction fees, transfer taxes or similar taxes or fees imposed by any governmental entity or self-regulatory organization in respect of such sales, shall constitute the net proceeds to the Company for such sales (the “Net Proceeds”), payment of which shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company against delivery to the applicable Agents of the Shares purchased by them. The applicable Agent shall notify the Company as promptly as practicable if any deduction referenced in the preceding sentence will be made. Notwithstanding the foregoing, in the event the Company engages an Agent as sales agent for the sale of Shares that would constitute a “distribution” within the meaning of Rule 100 of Regulation M under the Exchange Act, the Company and such Agent will agree to compensation for such Agent that is customary for such sales. For the avoidance of doubt, the compensation and commissions payable pursuant to this Section 2(d) all constitute consideration for services rendered and not consideration for the applicable Shares.

(e)If acting as sales agent hereunder, the applicable Agent shall provide written confirmation to the Company following the close of trading on the NYSE on each Trading Day on which Shares are sold under this Agreement setting forth the number of Shares sold on such day, the aggregate gross sales proceeds of the Shares, the aggregate Net Proceeds to the Company or the aggregate net proceeds to the applicable Forward Purchaser and the aggregate compensation payable by the Company to such Agent with respect to such sales.

(f)Under no circumstances shall the aggregate gross sales price for or number of, as the case may be, Shares offered or sold pursuant to this Agreement, or which are the subject of instructions to an Agent as sales agent pursuant to Section 2(b) hereof, exceed the aggregate gross sales price for or number of, as the case may be, Shares (i) referred to in the preamble paragraph of this Agreement, as reduced by prior sales of Shares under this Agreement, (ii) available for sale under the Registration Statement or (iii) duly authorized from time to time to be issued and sold under this Agreement by the Company or approved for listing on the NYSE. In addition, under no circumstances shall any Shares with respect to which the Agent acts as sales agent be offered or sold, or be the subject of instructions to an Agent as sales agent pursuant to Section 2(b) hereof, at a price lower than the minimum price therefor duly authorized from time to time by the Company and notified to the Agent(s) in writing (email shall constitute written notice for this Section 2(f)). The Agents shall have no responsibility for maintaining records with respect to Shares available for sale under the Registration Statement or for determining the aggregate gross sales price, number or minimum price of Shares duly authorized by the Company.

(g)If the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Company or the Shares, the Company shall promptly notify the Agents and future offers and sales of Shares through the Agents on an agented basis under this ATM Equity Offering Sales Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(h)Settlement for sales of Shares will occur on the first business day that is also a Trading Day following the trade date on which such sales are made, unless another date shall be agreed to in writing by the Company and the applicable Agents (each such day, a “Settlement Date”). Notwithstanding the foregoing, the Confirmations shall be settled separately in accordance with their terms. On each Settlement Date for the sale of Shares through an Agent as sales agent of the Company, such Shares shall be delivered by the Company to such Agent in book-entry form to such Agent’s account at The Depository Trust Company against payment by such Agent of the Net Proceeds from the sale of such Shares in same day funds delivered to an account designated by the Company. If the Company shall default on its obligation to deliver Shares through an Agent as sales agent of the Company on any Settlement Date, the Company shall (i) indemnify and hold such Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company and (ii) pay such Agent any commission to which it would otherwise be entitled absent such default.

(i)Notwithstanding any other provision of this Agreement, the Company shall not offer or sell, or instruct an Agent to offer or sell, any Shares through an Agent as sales agent of the Company or as forward seller (and, by notice to the applicable Agents given by telephone (confirmed promptly by telecopy or email), shall cancel

any instructions for any such offer or sale of any Shares prior to the commencement of the periods referenced below), and the Agents shall not be obligated to make any such offer or sale of Shares, during any period in which the Company is in possession of material non-public information.

(j)If the Company wishes to offer or sell Shares to an Agent as sales agent of the Company or as forward seller at any time during the period from and including the time the Company issues a press release containing, or shall otherwise publicly announce, its earnings, revenues or other operating results for a fiscal period or periods (each, an “Earnings Announcement”) through and including the time that is 24 hours after the time that the Company files a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated financial statements as of and for the same fiscal period or periods, as the case may be, covered by such Earnings Announcement, the Company shall first (i) prepare and deliver to such Agent and the applicable Forward Purchaser (with a copy to counsel for the Agents and the Forward Purchasers) a Current Report on Form 8-K that includes substantially the same financial and related information (together with management’s discussion and analysis thereof) that was included in such Earnings Announcement (other than any earnings projections and similar forward-looking data and officers’ quotations) (each, an “Earnings 8-K”), in form and substance reasonably satisfactory to such Agent and Forward Purchaser, and, prior to its filing, obtain the written consent of such Agent and Forward Purchaser to such filing (which consent shall not be unreasonably withheld, conditioned or delayed), (ii) provide such Agent with the officers’ certificate, opinions and letters of counsel and accountants’ letter specified in Section 3(o), (p) and (q), respectively, hereof, (iii) afford such Agent and Forward Purchaser the opportunity to conduct a due diligence review in accordance with Section 3(s) hereof prior to filing such Earnings 8-K and (iv) file such Earnings 8-K with the Commission. For purposes of clarity, the parties hereto agree that (A) the delivery of any officers’ certificate, opinion or letter of counsel or accountants’ letter pursuant to this Section 2(j) shall not relieve the Company from any of its obligations under this Agreement with respect to any Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, including, without limitation, the obligation to deliver officers’ certificates, opinions and letters of counsel and accountants’ letters as provided in Section 3(o), (p) and (q), respectively, hereof unless such obligations have been waived hereunder, and (B) this Section 2(j) shall in no way affect or limit the operation of clause (i) of Section 2(i) hereof, which shall have independent application.

(k)The Agents shall not have any obligation to purchase Shares as principal, whether from the Company or otherwise, unless the Company and the applicable Agent(s) agree as set forth in this Section 2(k). Shares purchased from the Company by the applicable Agent(s), individually or in a syndicate, as principal shall be made in accordance with terms agreed upon between such Agent(s) and the Company as evidenced by a Terms Agreement. The applicable Agents’ commitment to purchase Shares from the Company as principal shall be deemed to have been made on the basis of the accuracy of the representations and warranties of the Company, and performance by the Company of its covenants and other obligations, herein contained and shall be subject to the terms and conditions herein set forth. At the time of each Terms Agreement, the applicable Agent(s) shall specify the requirements, if any, for the officers’ certificate, opinions and letters of counsel and accountants’ letter pursuant to Section 3(o), (p) and (q), respectively, hereof. In the event of a conflict between the terms of this ATM Equity Offering Sales Agreement and a Terms Agreement, the terms of such Terms Agreement shall control.

(l)As set out in the Confirmations and notwithstanding anything herein to the contrary, in the event that either (i) a Forward Purchaser is unable to borrow and deliver any Shares for sale under this Agreement pursuant to the terms of such Confirmation, or (ii) in the commercially reasonable judgment of a Forward Purchaser, it is either impracticable to do so or the Forward Purchaser would incur a stock loan cost that is equal to or greater than the rate per annum set forth in Section 7(f)(i) of the applicable Confirmation, then the applicable Agent, as forward seller, shall be obligated to use commercially reasonable efforts to sell only the aggregate number of Shares that such Forward Purchaser is able to, and that in the commercially reasonable judgment of such Forward Purchaser it is practicable to, so borrow below such cost. For the avoidance of doubt, any obligation hereunder with respect to the borrowing of or offer or sale of any Shares in connection with a forward stock purchase transaction shall be subject to the related Confirmation being effective and not having been terminated.

Section 3. Covenants. The Company agrees with the Agents and the Forward Purchasers:

(a)Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b) and 3(c) hereof, will use its commercially reasonable efforts to comply in all material respects with the requirements of Rule 430B, and will notify the Agents and the Forward Purchasers promptly, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement or any new registration statement, in each case relating to the Shares for sale under this Agreement, shall become effective or any amendment or supplement to the Prospectus shall have been filed (other than an amendment or supplement providing solely for the determination of the terms of an offering of securities unless related to an offering of Shares for sale under this Agreement, as to which the Company will only be obligated to notify the applicable Agents and Forward Purchasers, and other than an amendment or supplement through incorporation of any report or other document filed under the Exchange Act), (ii) of the receipt of any comments from the Commission relating to the Registration Statement, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus, including any document incorporated by reference therein, or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any notice of objection to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) or of the issuance of any order preventing or suspending the use of any preliminary prospectus relating to an offering of Shares for sale under this Agreement or the Prospectus or any amendment or supplement thereto, or of the suspension of the qualification of any Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(d) or 8(e) of the Securities Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the Securities Act in connection with any offering of Shares. In connection with a Terms Agreement, the Company will prepare and file with the Commission, subject to Section 3(c) hereof, a pricing supplement with respect to the offer and sale of Shares covered by such Terms Agreement. The Company will effect all filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)). The Company will make reasonable efforts to prevent the issuance of any stop, prevention or suspension order and, if any such order is issued, to obtain the lifting thereof promptly. In the event of any issuance of a notice of objection by the Commission, the Company shall take all commercially reasonable action to permit offers and sales of Shares by or through the Agents, including, without limitation, amending the Registration Statement or filing a new shelf registration statement relating thereto. Notwithstanding the foregoing, the Company shall not be required to file such amendment or supplement if the Company has not instructed any Agent to sell Shares as provided in Section 2(b) and the Company believes that it is in its best interests not to file such amendment or supplement. The Company shall pay the required Commission filing fees relating to the Shares prior to the time the initial Prospectus Supplement is filed with the Commission or the time any subsequent Prospectus Supplement that increases the aggregate gross sales price or number of Shares that may offered and sold under this Agreement from that referenced in the immediately preceding Prospectus Supplement filed with the Commission.

(b)Continued Compliance with Securities Laws. The Company will use its commercially reasonable efforts to comply in all material respects with the Securities Act, the Securities Act Regulations, the Exchange Act and the Exchange Act Regulations so as to permit the completion of sales of Shares as contemplated in this Agreement and in the Registration Statement, the General Disclosure Package and the Prospectus. If at any time when a prospectus is required to be delivered (or but for the exception afforded by Rule 172 of the 1933 Act Regulations would be required to be delivered) under the 1933 Act Regulations in connection with sales of Shares, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Agents or counsel to the Company, to (i) amend the Registration Statement in order that the Registration Statement will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) amend or supplement the General Disclosure Package or the Prospectus in order that the General Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser or (iii) amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus, as the case may be in order to comply with the requirements of the Securities Act, the Securities Act Regulations, the Exchange Act or the Exchange Act Regulations, the Company will promptly (A) give the Agents and Forward Purchasers or, in the case of an offer and sale of Shares to the applicable Agents as principal, such Agents written notice of such event or condition, (B) prepare any amendment or supplement as may be necessary to correct such

statement or omission or to comply with such requirements and, a reasonable amount of time prior to any proposed filing or use, furnish the Agents and Forward Purchasers or such Agents, as the case may be, with copies of any such amendment or supplement and (C) file with the Commission any such amendment or supplement and use its commercially reasonable efforts to have any amendment to the Registration Statement declared effective by the Commission as soon as practicable if the Company is no longer eligible to file an automatic shelf registration statement; provided, however, that, during any period in which the Company has instructed any Agent to sell Shares as provided in Section 2(b), the Company shall not file or use any such amendment or supplement to which the Agents and Forward Purchasers or such Agents, as the case may be, or counsel for the Agents and Forward Purchasers shall reasonably object. Notwithstanding the foregoing, the Company shall not be required to file such amendment or supplement if the Company has not instructed any Agent to sell Shares as provided in Section 2(b) and the Company believes that it is in its best interests not to file such amendment or supplement.

(c)Filing or Use of Amendments and Supplements. The Company will give the Agents and Forward Purchasers or, in the case of an offer and sale of Shares to the applicable Agents as principal, such Agents written notice of its intention to file or use (i) any amendment to the Registration Statement or the Prospectus (other than (A) an amendment or supplement thereto relating solely to the offering of securities unless related to an offering of Shares and (B) an amendment through incorporation by reference of any report or document filed under the Exchange Act that contains no more information related to the matters contemplated by this Agreement than is necessary to comply with Section 3(n) hereof), if such proposed amendment or supplement relates to the matters contemplated by this Agreement, (ii) any new Prospectus Supplement that includes information in addition to the information referred to in Section 3(n) hereof or (iii) a pricing supplement disclosing the offer and sale of Shares covered by a Terms Agreement, will furnish the Agents and Forward Purchasers or such Agents, as the case may be, with copies of any such document a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Agents and Forward Purchasers or such Agents, as the case may be, or counsel for the Agents and Forward Purchasers shall reasonably object.

(d)Delivery of Registration Statements. The Company has furnished or, to the extent not available on EDGAR, will deliver to the Agents, Forward Purchasers and counsel for the Agents and Forward Purchasers, without charge, upon written request, signed copies of the Registration Statement as originally filed and each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts. The signed copies of the Registration Statement and each amendment thereto furnished to the Agents, Forward Purchasers and counsel for the Agents and Forward Purchasers will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e)Delivery of Prospectuses. The Company will furnish to the Agents and Forward Purchasers or, in the case of an offer and sale of Shares to the applicable Agents as principal, such Agents, without charge, upon execution of this Agreement and thereafter during the period in which a prospectus is (or, but for the exception afforded by Rule 172 of the Securities Act Regulations (“Rule 172”), would be) required by the Securities Act to be delivered in connection with any offer or sale of Shares, such number of copies of the Prospectus (as amended or supplemented) as the Agents and Forward Purchasers or such Agents, as the case may be, may reasonably request. The Company will also furnish, upon request of the Agents and Forward Purchasers or such Agents, as the case may be, copies of the Prospectus (as amended or supplemented) to each exchange or market on which sales of Shares were made as may be required by the rules and regulations of such exchange or market. The Prospectus and any amendments or supplements thereto furnished in accordance with this Section 3(e) will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(f)Reporting Requirements. The Company, during the period in which a prospectus is (or, but for the exception afforded by Rule 172, would be) required by the Securities Act to be delivered in connection with any offer or sale of Shares, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods prescribed by, and meeting the requirements of, the Exchange Act and the Exchange Act Regulations.

(g)Blue Sky Qualifications. The Company will use its commercially reasonable efforts, in cooperation with the Agents and Forward Purchasers or, in the case of an offer and sale of Shares to the applicable Agents as principal, such Agents to qualify the Shares, including any Confirmation Shares for offering and sale under the applicable securities laws of such states and non-U.S. jurisdictions as the Agents and Forward Purchasers or such Agents, as the case may be, may, from time to time, reasonably designate and to maintain such qualifications in effect so long as required to complete the sale of the Shares contemplated by this Agreement; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or not already so subject or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(h)Earnings Statement. The Company will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable after each effective date of the Registration Statement an earnings statement of the Company and its consolidated subsidiaries (which need not be audited) complying with Section 11(a) of the Securities Act and the Securities Act Regulations (including, at the option of the Company, Rule 158), which requirement may be satisfied by publicly filing the required information on EDGAR.

(i)Use of Proceeds. The Company will use the Net Proceeds received by it from the sale of the Shares pursuant to this Agreement in the manner specified in the Registration Statement, the General Disclosure Package and the Prospectus under “Use of Proceeds.”

(j)Listing. The Company will use its commercially reasonable efforts to effect and maintain the listing of the Shares and any Confirmation Shares on, and satisfy the requirements of, the NYSE.

(k)Notice of Certain Actions. During any period in which the Company has instructed any Agent to sell Shares as provided in Section 2(b), the Company will not, without the prior written consent of the Agents, unless it gives the Agents and the Forward Purchasers at least three business days’ prior written notice, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (collectively, “Convertible Securities”) or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Stock, any such Convertible Securities or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock, any Convertible Securities or any such other securities, in cash or otherwise or (iii) file any registration statement with the Commission relating to the offering of any shares of Common Stock or Convertible Securities. The foregoing sentence shall not apply to (A) the Shares, if any, sold by the Company hereunder, (B) the issuance by the Company of shares of Common Stock upon the exercise of an option or warrant or the conversion of or exchange for a Convertible Security outstanding on the date hereof, (C) the issuance by the Company of Common Stock or Convertible Securities in connection with any bona fide merger, acquisition, business combination or other strategic or commercial relationship, to a third party or a group of third parties, provided that the aggregate number of shares of Common Stock (including for purposes of such calculation the shares of Common Stock issuable on conversion, exercise, exchange or redemption of any such Convertible Securities) that the Company may sell or issue or agree to sell pursuant to this clause (C) shall not exceed 5% of the total number of shares of Common Stock of the Company outstanding as of the date hereof, (D) the issuance by the Company of any shares of Common Stock or options to purchase Common Stock or units or phantom shares convertible, exchangeable or exercisable for Common Stock currently outstanding or hereafter granted or issued pursuant to benefit plans, long-term incentive plans, savings (e.g. 401(k)) plans and other compensation plans of the Company or any of its subsidiaries in which employees and/or directors of the Company or its subsidiaries participate and which are referred to in the Registration Statement, the General Disclosure Package and the Prospectus or the documents filed with the Commission prior to the date of this Agreement that are incorporated by reference therein, or the filing of a registration statement or a post-effective amendment thereto relating to any such plan, (E) the issuance by the Company of any shares of Common Stock or options to purchase Common Stock or units or phantom shares convertible, exchangeable or exercisable for Common Stock currently outstanding or hereafter granted or issued pursuant to dividend reinvestment or direct stock purchase plans and which are referred to in the

Registration Statement, the General Disclosure Package and the Prospectus, or the filing of a registration statement or a post-effective amendment thereto relating to any such plan, (F) the issuance by the Company of shares of Common Stock upon the settlement of those certain Confirmations of Registered Forward Transaction dated November 7, 2023, by and between Sempra and Morgan Stanley & Co. LLC and Citibank, N.A., or (G) transactions under or pursuant to the Confirmations, including the issuance and transfer of Confirmation Shares pursuant thereto. Upon receipt of any written notice contemplated above, an Agent or Forward Purchaser may suspend its activity under this Agreement for such period of time as deemed appropriate by such Agent or Forward Purchaser.

(l)Issuer Free Writing Prospectuses. At all times during such period as the Prospectus is required to be delivered (or but for the exception afforded by Rule 172 of the 1933 Act Regulations would be required to be delivered) in connection with sales of the Shares, the Company represents and agrees that, unless it obtains the prior consent of the applicable Agents and Forward Purchasers, it will not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Company with the Commission or retained by the Company under Rule 433. The Company represents that it has treated or agrees that it will treat each such free writing prospectus consented to by the applicable Agents and Forward Purchasers as an “issuer free writing prospectus,” as defined in Rule 433, and that it will comply with the applicable requirements of Rule 433 with respect thereto, including timely filing with the Commission where required, legending and record keeping. If at any time following issuance of an Issuer Free Writing Prospectus any event shall occur or condition shall exist as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, any preliminary prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the applicable Agents and Forward Purchasers and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(m)No Stabilization or Manipulation. The Company agrees that neither it nor any controlled affiliate of the Company will take, directly or indirectly, any action which is designed, or would reasonably be expected, to cause or result in, or which constitutes, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of any Shares or to result in a violation of Regulation M under the Exchange Act.

(n)Update of Activity under this Agreement. The Company shall disclose (i) in each Annual Report on Form 10-K or Quarterly Report on Form 10-Q filed by the Company in respect of any fiscal quarterly period (which, in the case of an Annual Report on Form 10-K, would mean the last quarterly period of the fiscal year) in which sales of Shares were made by or through an Agent under this Agreement (each date on which any such document is filed, a “Company Periodic Report Date”), or (ii) to the extent required by applicable law and/or interpretations of the Commission, in Prospectus Supplements for each such fiscal quarterly period, the number of Shares sold by or through the Agents under this Agreement during such fiscal quarterly period and the net proceeds received by the Company and the aggregate compensation paid by the Company to the Agents with respect to such sales.

(o)Delivery of Future Officers’ Certificates. Upon commencement of the offering of Shares under this Agreement, (A) each time Shares are delivered to the applicable Agents as principal on a Settlement Date with respect to the sale of Shares under this Agreement, and (B) promptly after each (i) date on which the Registration Statement shall be amended or a new registration statement relating to the offer and sale of Shares pursuant to this Agreement shall become effective or the Prospectus shall be amended or supplemented (other than (1) by an amendment or supplement providing solely for the determination of the terms of securities, including the Shares, (2) in connection with the filing of a Prospectus Supplement that contains solely the information referred to in Section 3(n) hereof, (3) in connection with the filing of any Current Report on Form 8-K (other than an Earnings 8-K and any other Current Report on Form 8-K which contains financial statements, supporting schedules or other financial data, including any Current Report on Form 8-K under Item 2.02 of such form that is considered “filed” under the Exchange Act), (4) any amendment or supplement through incorporation of any report or other document filed under the Exchange Act that contains no more information related to the matters contemplated by this Agreement than is necessary to comply with Section 3(n) hereof, or (5) by a prospectus supplement relating to the offering of securities

other than the Shares pursuant to this Agreement (including, without limitation, other shares of Common Stock)) (each such date, a “Registration Statement Amendment Date”), (ii) date on which an Earnings 8-K shall be filed with the Commission as contemplated by Section 2(j) hereof (a “Company Earnings Report Date”) and (iii) Company Periodic Report Date, the Company will furnish or cause to be furnished to the Agents and Forward Purchasers or, in the case of clause (A) above, the applicable Agents an officers’ certificate, dated such Settlement Date, such Registration Statement Amendment Date, such Company Earnings Report Date or such Company Periodic Report Date, as the case may be, in form and substance reasonably satisfactory to the Agents and Forward Purchasers, or, in the case of clause (A) above, such Agents, as the case may be, to the effect that the statements contained in the officers’ certificates referred to in Sections 5(f) and 5(h) hereof that were last furnished to the Agents and Forward Purchasers or, in the case of clause (A) above, such Agents, as the case may be, are true and correct as of the date of such certificates as though made at and as of the date of such certificates (except that such statements shall be deemed to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented at the date of such certificates) or, in lieu of such certificates, a certificate or certificates of the same tenor as the certificate or certificates referred to in Sections 5(f) and 5(h) hereof, but modified as necessary to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented at the date of such certificate. As used in this Section 3(o), to the extent there shall be a sale of Shares on or following any Registration Statement Amendment Date, Company Earnings Report Date or Company Periodic Report Date, “promptly” shall be deemed to be at or prior to the Applicable Time for such sale.

Notwithstanding the foregoing, if the Company subsequently decides to sell Shares following any Registration Statement Amendment Date or Company Periodic Report Date when the Company relied on such waiver and did not furnish or cause to be furnished to the Agents and the Forward Purchasers officers’ certificates pursuant to this Section 3(o), then before the Company instructs any Agent to sell any Shares or enters into any Terms Agreement with any Agent or Agents, the Company shall cause to be furnished to the Agents and the Forward Purchasers officers’ certificates pursuant to this Section 3(o) dated as of the date of delivery thereof.

(p)Delivery of Future Opinions and Letters of Counsel. Upon commencement of the offering of Shares under this Agreement, (A) each time Shares are delivered to the applicable Agents as principal on a Settlement Date with respect to the sale of Shares under this Agreement and (B) promptly after each Registration Statement Amendment Date, Company Earnings Report Date or Company Periodic Report Date, the Company will, unless the Agents or Forward Purchasers or, in the case of clause (A) above, the applicable Agents agree otherwise, furnish or cause to be furnished to the Agents and the Forward Purchasers or, in the case of clause (A) above, the applicable Agents the written opinions and letters of each of counsel to the Company (who shall be reasonably acceptable to the Agents and the Forward Purchasers) or, in the case of clause (A) above, such Agents, as the case may be,) and counsel to the Agents and the Forward Purchasers, dated such Settlement Date, such Registration Statement Amendment Date, such Company Earnings Report Date or such Company Periodic Report Date, as the case may be, in form and substance reasonably satisfactory to the Agents and the Forward Purchasers, or, in the case of clause (A) above, such Agents, as the case may be, of the same tenor as the respective opinions and letters referred to in Section 5(b) and 5(c), as applicable, hereof but modified as necessary to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented to the date of such opinion and letter or, in lieu of any such opinion and letter, counsel last furnishing such opinion and letter to the Agents and the Forward Purchasers or, in the case of clause (A) above, such Agents, as the case may be, shall furnish the Agents and the Forward Purchasers or, in the case of clause (A) above, such Agents, as the case may be, with a letter substantially to the effect that the Agents and the Forward Purchasers or, in the case of clause (A) above, such Agents, as the case may be, may rely on such counsel’s last opinion and letter to the same extent as though each were dated the date of such letter authorizing reliance (except that statements in such last opinion and letter shall be deemed to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented to the date of such letter authorizing reliance). As used in this Section 3(p), to the extent there shall be a sale of Shares on or following any Registration Statement Amendment Date, Company Earnings

Notwithstanding the foregoing, if the Company subsequently decides to sell Shares following any Registration Statement Amendment Date or Company Periodic Report Date when the Company relied on such waiver and did not furnish or cause to be furnished to the Agents and the Forward Purchasers the opinions and letters pursuant to this Section 3(p), then before the Company instructs any Agent to sell any Shares or enters into any Terms Agreement with any Agent or Agents, the Company shall cause to be furnished to the Agents and the Forward Purchasers the opinions and letters pursuant to this Section 3(p) dated as of the date of delivery thereof.

(q)Delivery of Future Accountants’ Letters. Upon commencement of the offering of Shares under this Agreement, (A) each time Shares are delivered to the applicable Agents as principal on a Settlement Date with respect to the sale of Shares under this Agreement and (B) promptly after each Registration Statement Amendment Date, Company Earnings Report Date or Company Periodic Report Date, the Company will, unless the Agents or Forward Purchasers or, in the case of clause (A) above, the applicable Agents agree otherwise, cause each of (i) its independent accountants and (ii) Oncor Holdings’ independent accountants to furnish to the Agents and the Forward Purchasers or, in the case of clause (A) above, the applicable Agents a letter, dated such Settlement Date, such Registration Statement Amendment Date, such Company Earnings Report Date or such Company Periodic Report Date, as the case may be, in form and substance reasonably satisfactory to the Agents and the Forward Purchasers, or, in the case of clause (A) above, such Agents, as the case may be, of the same tenor as the letters referred to in Section 5(d) hereof but modified as necessary to relate to the Registration Statement, the General Disclosure Package and the Prospectus as amended and supplemented to the date of such letter. As used in this paragraph, to the extent there shall be a sale of Shares on or following any Registration Statement Amendment Date, Company Earnings Report Date or Company Periodic Report Date, “promptly” shall be deemed to be at or prior to the Applicable Time for such sale.

The requirement to cause to be furnished accountant letters pursuant to this Section 3(q) shall be waived for any Registration Statement Amendment Date or Company Periodic Report Date occurring at a time at which the Company has not instructed any Agent to sell Shares as provided in Section 2(b), which waiver shall continue until the date on which the Company delivers such an instruction as provided in Section 2(b). Notwithstanding the foregoing, if the Company subsequently decides to sell Shares following any Registration Statement Amendment Date or Company Periodic Report Date when the Company relied on such waiver and did not furnish or cause to be furnished to the Agents and the Forward Purchasers accountant letters pursuant to this Section 3(q), then before the Company instructs any Agent to sell any Shares or enters into any Terms Agreement with any Agent or Agents, the Company shall cause to be furnished to the Agents accountant letters pursuant to this Section 3(q) dated as of the date of delivery thereof.

(r)Trading in the Common Stock. The Company consents to the Agents and the Forward Purchasers trading in the Company’s Common Stock for their own account and for the account of their clients at the same time as sales of Shares occur pursuant to this Agreement. Notwithstanding the foregoing, the Company is not responsible for the compliance by the Agents or the Forward Purchasers or their respective affiliates with laws and regulations (including Regulation M) that apply to them with respect to any such trading.

(s)[Reserved.]

(t)Due Diligence Review.

(u)Renewal. If, immediately prior to the third anniversary of the initial effective date of the Registration Statement (the “Renewal Deadline”), Shares remain unsold hereunder and this Agreement is still in effect and any Shares purchased by an Agent as principal, or to be sold through an Agent as sales agent or as forward seller pursuant to a Company instruction, remain unsold, the Company will, prior to the Renewal Deadline, (i) promptly notify the Agents and the Forward Purchasers, (ii) promptly file, if it is eligible to do so, a new automatic shelf registration statement relating to the Shares, in a form and substance satisfactory to the Agents and the Forward Purchasers, (iii) promptly notify the Agents and the Forward Purchasers of such filing and (iv) prepare a prospectus supplement relating to the Shares and, promptly after the effectiveness of such new registration statement, file such prospectus supplement, together with the base prospectus filed as part of such registration statement, with the Commission in accordance of the provisions of Rule 424(b) of the Securities Act Regulations. If, at the time the Company intends to file such a new automatic shelf registration statement, it is not eligible to do so, the Company will, prior to the Renewal Deadline, (a) promptly notify the Agents and the Forward Purchasers, (b) promptly file a new shelf registration statement on the proper form relating to the Shares, in a form and substance satisfactory to the Agents and the Forward Purchasers, (c) use its best efforts to cause such new shelf registration statement to be declared effective within 60 days after the Renewal Deadline or, if Shares purchased by an Agent as principal remain unsold, use its best efforts to cause such new shelf registration statement to be declared effective as soon as reasonably possible after the Renewal Deadline, (d) promptly notify the Agents and the Forward Purchasers of such effectiveness and (e) prepare a prospectus supplement relating to the Shares and, promptly after the effectiveness of such new registration statement, file such prospectus supplement, together with the base prospectus filed as part of such new registration statement, with the Commission in accordance with the provisions of Rule 424(b) of the Securities Act Regulations. In the event that the Company files a new shelf registration statement pursuant to the immediately preceding sentence, the Company shall not be required to certify or otherwise represent, pursuant to Section 5(f) or otherwise, that the representation contained in Section 1(v) hereof is true and correct with respect to such registration statement. In addition, the Company may, at its option, file a new automatic shelf registration statement relating to the Shares (which, upon effectiveness, shall replace the then-existing shelf registration statement relating to the Shares) for any reason at any time, so long as (1) this Agreement is still in effect and (2) no Shares purchased by any Agent as principal remain unsold or Shares are to be sold through an Agent as sales agent or forward seller pursuant to a Company instruction, and provided that the Company (w) notifies the Agents and the Forward Purchasers prior to filing such new automatic shelf registration statement, (x) files a new automatic shelf registration statement relating to the Shares in a form and substance satisfactory to the Agents and the Forward Purchasers, (y) promptly notifies the Agents and Forward Purchases of such filing and (z) prepares a prospectus supplement relating to the Shares and, promptly after the effectiveness of such new registration statement, files such prospectus supplement, together with the base prospectus filed as part of such registration statement, with the Commission in accordance with the provisions of Rule 424(b) of the Securities Act Regulations. In each of the foregoing cases, the Company will take all other action necessary or appropriate to permit the offering and sale of the Shares to continue as contemplated in the Registration Statement and the Prospectus in effect immediately prior to the filing of any such new shelf registration statement. From and after the effectiveness of any such new shelf registration statement, references herein to the “Registration Statement” and references to “such registration statement” appearing in the second and third sentences of the fourth paragraph of this Agreement shall be deemed to mean such new registration statement, mutatis mutandis, and, from and after the filing of any such new prospectus supplement and base prospectus pursuant to Rule 424(b) of the Securities Act Regulations, references herein to the “Prospectus Supplement” and the “Base Prospectus,” the reference to the “base prospectus” appearing in the third sentence of the fourth paragraph of this Agreement, the reference to “a prospectus supplement” appearing in the fourth sentence of the fourth paragraph of this Agreement, and the reference to “such prospectus supplement” appearing in the fifth sentence of the fourth paragraph of this Agreement, shall be deemed to mean such new prospectus supplement or such new base prospectus, as applicable, mutatis mutandis.

(v)Ceasing Eligibility For Use of Automatic Shelf Registration Statement Form. If, at any time, during the term of this Agreement or otherwise when Shares purchased by an Agent as principal remain unsold, the Company receives a notice from the Commission pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Agents and the Forward Purchasers, (ii) promptly file a new shelf registration statement or post-effective amendment on the proper form relating to such Shares, in form and substance reasonably satisfactory to the Agents and the Forward Purchasers, (iii) use its commercially reasonable efforts to cause such new shelf registration statement or post-effective amendment

to be declared effective as soon as practicable and (iv) promptly notify the Agents and the Forward Purchasers of such effectiveness. The Company will take all commercially reasonable action necessary or appropriate to permit the offering and sale of the Shares to continue as contemplated in the Registration Statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible.

Section 6. Indemnification.

(a)Indemnification of the Agents and Forward Purchasers. The Company will indemnify and hold harmless each Agent and each Forward Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Agent or Forward Purchaser may become subject, under the Securities 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, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Shares, 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 Agent and each Forward Purchaser for any legal or other expenses reasonably incurred by such Agent or Forward Purchaser 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, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Shares or any amendment or supplement thereto in reliance upon and in conformity with the Agent Information.

(b)Indemnification of Company. Each Agent and Forward Purchaser, 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 Securities 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, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Shares, 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, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Shares or any such amendment or supplement thereto in reliance upon and in conformity with the Agent Information 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. As used in this Agreement with respect to an Agent and a Forward Purchaser and an applicable document, “Agent Information” shall mean the written information furnished to the Company by such Agent or Forward Purchaser expressly for use therein; it being understood and agreed upon that the only such information furnished by any Agent or Forward Purchaser consists of such Agent’s or Forward Purchaser’s name appearing in the Prospectus.

(c)Actions against Parties; Notification. 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 reasonably 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 Agents and Forward Purchasers shall have the right to employ counsel to represent jointly the Agents and Forward Purchasers 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 Agents or Forward Purchasers against the Company under this Section 6 if the Agents and Forward Purchasers shall have reasonably concluded that there may be one or more legal defenses available to the Agents and Forward Purchasers 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 Forward Purchasers shall have the right to employ counsel to represent jointly the Forward Purchasers 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 Forward Purchasers against the Company or any Agent under this Section 6 if the Forward Purchasers shall have reasonably concluded that there may be one or more legal defenses available to the Forward Purchasers 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 (if the indemnifying person is the Company) or different from or additional to those available to the Agents and their respective directors, officers, employees, agents and controlling persons (if the indemnifying person is any Agent), and in each case the fees and expenses of a single separate counsel for the Agents and their respective directors, officers, employees, agents and controlling persons (in addition to local counsel) shall be paid by the Company and the fees and expenses of a single separate counsel for the Forward Purchasers and their respective directors, officers, employees, agents and controlling persons (in addition to local counsel) shall be paid by the Company or the applicable Agent or Agents, as the case may be. 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 prior 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 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)Contribution. If the indemnification provided for in this Section 6 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 applicable Agents and Forward Purchasers on the other, from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, or if the indemnified party failed to give the notice required 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 applicable Agents and Forward Purchasers 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 applicable Agents and Forward Purchasers on the other, in connection with the applicable offering of Shares, shall be deemed to be in the same respective proportions as (x) in the case of the Company, the total net proceeds from the offering of the Shares(before deducting expenses) received by the Company (such total net proceeds shall include the total proceeds that would be received by the Company pursuant to any Confirmations assuming full physical settlement of such Confirmations assuming the aggregate amount payable by such Forward Purchaser to the Company for such Confirmation Shares is equal to the aggregate amount of net proceeds received by such Forward Purchaser from the sale of such Shares through such Agent), (y) in the case of the Agents, the total underwriting discounts and commissions received by the Agents from the offering of the Shares and (z) in the case of the Forward Purchasers, the aggregate Spread (as defined in the Confirmations) retained by the Forward Purchasers under the Confirmations, net of any costs associated therewith, as reasonably determined by the Forward Purchasers, bear to an amount equal to the sum of the amounts set forth in (x), (y) and (z) above. 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 Agents or Forward Purchasers on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Agents and Forward Purchasers 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 Agents and the Forward Purchasers 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 Agent shall be required to contribute any amount in excess of the amount by which the total commissions or underwriting discounts received by such Agent in connection with Shares placed or underwritten by it for sale to the public exceeds the amount of any damages which such Agent 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Agent and Forward Purchasers in this subsection (d) to contribute are several in proportion to their respective obligations and not joint.

(e)Directors, Officers, Employees and Agents. The obligations of the Company under this Section 6 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 Agent or Forward Purchaser and each person, if any, who controls any Agent or Forward Purchaser within the meaning of the Securities Act; and the obligations of the Agents and Forward Purchasers under this Section 6 shall be in addition to any liability which the respective Agents and Forward Purchasers 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 Securities Act.

Section 7. [Reserved.]

Section 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of an Agent, a Forward Purchaser or their respective affiliates, selling agents, officers or directors or any person controlling such Agent or Forward Purchaser, or the Company or its officers or directors, or any person controlling the Company and (ii) delivery of and payment for the Shares.

Section 9. Termination.

(a)This ATM Equity Offering Sales Agreement may be terminated for any reason, at any time, by either the Company, an Agent or Forward Purchaser, as to itself, upon giving prior written notice to the other parties hereto.

(b)The applicable Agents may terminate a Terms Agreement to which they are a party, at any time at or prior to the Settlement Date, (i) if, since the time of execution of such Terms Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, (a) the Company and its subsidiaries, taken as a whole, have sustained, since the date of the latest audited financial statements included or incorporated by reference in the Registration Statement, the General Disclosure Package or the Prospectus, any material 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 Registration Statement, the General Disclosure Package and the Prospectus, or (b) since the respective dates as of which information is given in the General Disclosure Package and the Prospectus, there has 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 General Disclosure Package and the Prospectus, the effect of which, in any such case described in this clause (i)(a) or (i)(b), is in the judgment of the applicable Agents 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 offering or delivery of the Shares subject to such Terms Agreement, or (ii) if a suspension or material limitation in trading in securities generally on the NYSE or the Nasdaq Global Market occurs, or (iii) if a suspension or material limitation in trading in the Company’s securities on the NYSE occurs, or (iv) if 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 settlements or clearance services in the United States occurs, or (v) if the outbreak or escalation of hostilities involving 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 occurs, if the effect of any such event specified in this clause (v) in the judgement of such applicable Agents (A) is material and adverse and (B) makes it impracticable or inadvisable to proceed with the offering or delivery of the Shares subject to such Terms Agreement.

(c)If the Company and two or more Agents enter into a Terms Agreement pursuant to which such Agents agree to purchase Shares from the Company as principal and one or more of such Agents shall fail at the Settlement Date to purchase the Shares which it or they are obligated to purchase (the “Defaulted Shares”), then the nondefaulting Agents shall have the right, within 24 hours thereafter, to make arrangements for one of them or one or more other Agents or underwriters to purchase all, but not less than all, of the Defaulted Shares in such amounts as may be agreed upon and upon the terms set forth herein and in the applicable Terms Agreement; provided, however, that if such arrangements shall not have been completed within such 24-hour period, then:

(i)if the number of Defaulted Shares does not exceed 10% of the number of Shares to be so purchased by all of such Agents on the Settlement Date, the nondefaulting Agents shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective initial purchase obligation bears to the purchase obligations of all nondefaulting Agents; or

(ii)if the number of Defaulted Shares exceeds 10% of the number of Shares to be so purchased by all of such Agents on the Settlement Date, such Terms Agreement shall terminate without liability on the part of any nondefaulting Agent.

No action taken pursuant to this Section 9(c) shall relieve any defaulting Agent from liability in respect of its default. In the event of any such default which does not result in a termination of such Terms Agreement, either the nondefaulting Agents or the Company shall have the right to postpone the Settlement Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements.

(d)    In the event of any termination under this Section 9, no party will have any liability to the other parties hereto, except that (i) the Agents shall be entitled to any commissions earned in accordance with Section 2(b) hereof, (ii) if at the time of termination (a) an Agent shall own any Shares purchased by it as principal or (b) an offer to purchase any Shares has been accepted by the Company but the Settlement Date has not occurred, the covenants set forth in Section 3 hereof shall remain in effect until such Shares are resold or so delivered, as the case may be, and (iii) the covenant set forth in Section 3(h) hereof, the provisions of Section 4 hereof, the indemnity and contribution agreements set forth in Sections 6 and 7 hereof, and the provisions of Sections 8, 13, 14, 15 and 16 hereof shall remain in effect.

Section 11. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that the Agents and Forward Purchasers are acting solely in the capacity of arm’s length contractual counterparties to the Company with respect to the offering of the Shares 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. The Company agrees that it will not claim that the Agents or Forward Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with the transactions contemplated hereby or the process leading thereto. Additionally, no Agent or Forward Purchaser 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 its own independent investigation and appraisal of the transactions contemplated hereby, and the Agents and the Forward Purchasers shall have no responsibility or liability to the Company with respect thereto. Any review by the Agents or the Forward Purchasers of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Agents or the Forward Purchasers and shall not be on behalf of the Company, and none of the activities of the Agents or the Forward Purchasers in connection with the transactions contemplated herein constitutes a recommendation or investment advice by the Agents or the Forward Purchasers with respect to any entity or natural person.

Section 13.Parties. This Agreement shall be binding upon, and inure solely to the benefit of, the Agents, the Forward Purchasers (to the extent provided for herein), the Company and, to the extent provided in Section 6 hereof, the directors, officers, employees and agents of each Agent and each Forward Purchaser, the officers, directors and employees of the Company and each person who controls the Company or any Agent or Forward Purchaser, 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 Shares from any Agent or Forward Purchaser shall be deemed a successor or assign by reason merely of such purchase. Notwithstanding the foregoing, in the event that an entity acting as Forward Purchaser (the “Previous Forward Purchaser”) is replaced as a party hereunder by its affiliate (the “New Forward Purchaser”), then, from the date of such transfer/assignment, the New Forward Purchaser shall for all purposes of this Agreement be substituted for the Previous Forward Purchaser as a Forward Purchaser party hereto (as assignee of the Previous Forward Purchaser).

Section 14. Trial by Jury. Each of the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates), and the Agents and the Forward Purchasers hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Section 15. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

Section 16. Consent to Jurisdiction; Waiver of Immunity. Each of the Company, the Forward Purchasers and the Agents agrees that any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any Specified Court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of the Specified Courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to a party’s address set forth in Section 10 hereof shall be effective service of process upon such party for any suit, action or proceeding brought in any Specified Court. Each of the Company, the Forward Purchasers and the Agents irrevocably and unconditionally waives any objection to the laying of venue of any suit, action or proceeding in the Specified Courts and irrevocably and unconditionally waives and agrees not to plead or claim in any Specified Court that any such suit, action or proceeding brought in any Specified Court has been brought in an inconvenient forum.

Section 17. TIME. TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

Section 18. Counterparts. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. The words “execution,” “signed,” “signature,” and words of like import in this Agreement and any Confirmations or in any instruments, agreements, certificates, officers’ certificates, Company orders, legal opinions, negative assurance letters or other documents entered into or delivered pursuant to or in connection with this Agreement or any Confirmations shall include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf,” “tif” or “jpg”) and electronic signatures (including, without limitation, DocuSign and AdobeSign), and this Agreement and any Confirmations and any instruments, agreements, certificates, officers’ certificates, legal opinions, Company orders, negative assurance letters or other documents entered into or delivered pursuant to or in connection with this Agreement or any Confirmations may be executed, attested and transmitted by any of the foregoing electronic means and formats. The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

Section 19. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

Ladies and Gentlemen:

Sempra, a California corporation (the “Company”), proposes, on the basis of the representations and warranties, and subject to the terms and conditions, stated herein and in the ATM Equity Offering Sales Agreement, dated November [●], 2024 (the “Sales Agreement”), between the Company and Barclays Capital Inc., BofA Securities, Inc., Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Mizuho Securities USA LLC, Morgan Stanley & Co. LLC, MUFG Securities Americas Inc., RBC Capital Markets, LLC, Scotia Capital (USA) Inc. and Wells Fargo Securities, LLC as sales agents, principals and/or, forward sellers (in any such capacity, each an “Agent”, and collectively, the “Agents”) and Barclays Bank PLC, Bank of America, N.A., Citibank, N.A., Goldman Sachs & Co. LLC, JPMorgan Chase Bank, National Association, Mizuho Markets Americas LLC, Morgan Stanley & Co. LLC, MUFG Securities EMEA plc, Royal Bank of Canada, The Bank of Nova Scotia and Wells Fargo Bank, National Association each as forward purchaser (in such capacity, each a “Forward Purchaser” and, collectively, the “Forward Purchasers”) to issue and sell to [●], [●], [●] and [●] as principal for resale (collectively, the “Underwriters”), and the Underwriters severally agree to purchase from the Company, the shares of Common Stock specified in the Schedule A hereto (the “[Initial] Securities”) [, and to grant to the Underwriters the option to purchase the additional shares of Common Stock specified in Schedule A hereto (the “Option Securities”, and together with the Initial Securities, the “Securities”)]*,[in each case]* on the terms specified herein, including Schedule A hereto, and in the Sales Agreement. Capitalized terms used but and not defined herein have the respective meanings ascribed thereto in the Sales Agreement.

[The Company grants an option to the Underwriters, severally and not jointly, to purchase up to an additional [●] Option Securities at the price per share set forth in Schedule A hereto, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted may be exercised for 30 days after the date hereof and may be exercised in whole or in part at any time from time to time upon notice by the Underwriters to the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Underwriters, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Settlement Date (as defined below). [If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A hereto opposite the name of such Underwriter bears to the total number of Initial Securities, subject, in each case, to such adjustments as [●] in its sole discretion shall make to eliminate any sales or purchases of fractional shares. For purposes of clarity, the parties hereto agree that the officers’ certificate, opinions and letter of counsel and accountants’ letter referred to in Section 3(o), (p) and (q), respectively, of the Sales Agreement are required to be delivered by or on behalf of the Company on the Settlement Date.]*

Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Sidley Austin LLP, New York, New York, or at such other place as shall be agreed upon by the

Underwriters and the Company, at 9:00 A.M. (New York City time) on the first (or second, if the pricing occurs after 4:30 P.M. (New York City time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 9(c) of the Sales Agreement), or such other time not later than ten business days after such date as shall be agreed upon by the Underwriters and the Company (such time and date of payment and delivery being herein called “Settlement Date”).

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Underwriters and the Company, on each Date of Delivery as specified in the notice from the Underwriters to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company against delivery to the Underwriters for their respective accounts of the Securities to be purchased by them. It is understood that each Underwriter has authorized [●] as representative of the Underwriters, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. [●], individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Settlement Date or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

Each of the provisions of the Sales Agreement not related solely to the Agent as sales agent of the Company or to the sale and issuance of Shares pursuant to forward sale agreements is incorporated herein by reference in its entirety, and shall be deemed to be part of this Terms Agreement to the same extent as if each such provision had been set forth in full herein. Each of the representations and warranties set forth in the Sales Agreement shall be deemed to have been made at and as of the date of this Terms Agreement, the Applicable Time and any Date of Delivery.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement between the Underwriters and the Company in accordance with its terms.

THIS TERMS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS TERMS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

*     Include only if the Underwriters have an option to purchase additional shares of Common Stock from the Company.

Ladies and Gentlemen:

(b)    Interpretive Letter. Counterparty agrees and acknowledges that the Transaction is being entered into in accordance with the October 9, 2003 interpretive letter from the staff of the Securities and Exchange Commission to Goldman, Sachs & Co. (the “Interpretive Letter”) and agrees to take all actions, and to omit to take any actions, reasonably requested by Dealer for the Transaction to comply with the Interpretive Letter. In addition, Counterparty represents that it is eligible to conduct a primary offering of Shares on Form S-3, the offering contemplated by the Equity Sales Agreement complies with Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), and the Shares are “actively traded” as defined in Rule 101(c)(1) of Regulation M promulgated under the Exchange Act (“Regulation M”).

(iii)    ISDA Termination. Either Dealer or Counterparty has the right to designate an Early Termination Date pursuant to Section 6 of the Agreement, in which case, except as otherwise specified herein and except as a result of an Event of Default under Section 5(a)(i) of the Agreement, the provisions of Paragraph 7(f) below shall apply in lieu of the consequences specified in Section 6 of the Agreement; failure of Counterparty to deliver the Approval Notice by the third Exchange Business Day following the Hedge Completion Date (the “Approval Deadline Date”) shall constitute an Additional Termination Event (such event, an “Approval Deadline Event”), with (A) Counterparty the sole Affected Party, (B) an Early Termination Date deemed to have been designated by Dealer as of the Approval Deadline Date, and (C) the consequences specified in Section 6 of the Agreement, rather than the provisions of Paragraph 7(f) below, applying, except that Dealer may designate a date for payment of the Early Termination Amount that permits Dealer to effect a commercially reasonable unwind of any hedge position that Dealer may have in the Shares, taking into account relevant legal and regulatory considerations, and such payment date shall be notified by Dealer to Counterparty no later than one Scheduled Trading Day prior to such payment date; for the avoidance of doubt, no Additional Termination Event, Early Termination Date, or date for payment of an Early Termination Amount, in each case, in respect of an Approval Deadline Event, will occur prior to the Approval Deadline Date;

1 Exact representation will be updated for Dealers.

i.    [It is a chartered bank organized under the laws of Canada and is treated as a corporation for United States federal income tax purposes.
