Xxxxxx Securities LLC (each in its capacity as agent for the Company and/or principal in connection with the offering and sale of any Issuance Shares (as defined below) hereunder, an “Agent” and together, the “Agents”, and each in its capacity as agent for each Forward Purchaser

in connection with the offering and sale of any Forward Hedge Shares (as defined below) hereunder, a “Forward Seller” and together, the “Forward Sellers”), as follows:

SECTION 1. Description of Shares.

The Company has authorized and proposes to issue and sell, in the manner contemplated by this Agreement, Shares (as defined below) of the Company’s common stock, par value $0.001 per share (the “Common Stock”) having an aggregate Sales Price (as defined below) of up to $1,000,000,000 (the “Maximum Amount”), upon the terms and subject to the conditions contained herein. The issuance and sale of the Shares will be effected pursuant to the Registration Statement (as defined below) filed by the Company which became effective upon filing with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 462 of the rules and regulations of the Commission under the Securities Act (as defined below), although nothing in this Agreement shall be construed as requiring the Company to use the Registration Statement to issue the Shares. The Company agrees that whenever it determines to sell Shares directly to an Agent, as principal, it will enter into a separate written agreement with such Agent containing the terms and conditions of such sale.

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Securities Act”), with the Commission an automatic shelf registration statement on Form S-3, as amended (File No. 333-213765) (the “Original Registration Statement”), including a base prospectus, relating to certain securities, including the Shares to be issued from time to time by the Company, and which incorporates by reference documents that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”). The Company has prepared a prospectus supplement specifically relating to the Shares (the “Original Prospectus Supplement”) to the base prospectus included as part of the Original Registration Statement. Except where the context otherwise requires, the “Registration Statement” refers to (i) initially, the Original Registration Statement and (ii) on and after the date on which the Shares may no longer be offered and sold pursuant to the Original Registration Statement, the registration statement, if any, filed by the Company for the purpose of continuing the offering of the Shares following any such date, in each case, as amended when it became or becomes effective, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act or deemed to be a part thereof pursuant to Rule 430B under the Securities Act (the “Rule 430B Information”). The base prospectus, including all documents incorporated therein by reference, included in the Registration Statement, supplemented by the most recent prospectus supplement prepared by the Company specifically relating to the Shares, which shall initially be the Original Prospectus Supplement, in the form in which such prospectus and/or prospectus supplement have most recently been filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act is herein called the “Prospectus.” Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the documents incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the

Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or to any amendment or supplement thereto shall be deemed to include any copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“XXXXX”).

All references in this Agreement to financial statements and schedules and other information that is “contained,” “included” or “stated” in the Registration Statement or the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that is incorporated by reference in the Registration Statement or the Prospectus, as the case may be.

All references in this Agreement to any Issuer Free Writing Prospectus (as defined below) (other than any Issuer Free Writing Prospectuses that, pursuant to Rule 433 under the Securities Act, are not required to be filed with the Commission) shall be deemed to include the copy thereof filed with the Commission pursuant to XXXXX.

(a) On any Trading Day during the Commitment Period on which (i) the conditions set forth in Section 9 have been satisfied and (ii) with respect to any Forward, during a Forward Hedge Selling Period, the Company may issue (in the case of an Issuance) and sell or cause to be sold the Shares hereunder (each, a “Placement”), by the delivery of a notice to an Agent (in the case of an Issuance), or to a Forward Seller and the applicable Forward Purchaser (in the case of a Forward), in each case, by an email (or other method mutually agreed to in writing by the parties) containing the parameters in accordance with which it desires the Shares to be sold, which shall specify whether it relates to an “Issuance” or a “Forward” and include the maximum number of Shares to be sold (the “Placement Shares”), the time period during which sales are requested to be made, any limitation on the number of Shares that may be sold in any one day, any minimum price below which sales may not be made or a formula pursuant to which such minimum price shall be determined and, as applicable, certain specified terms of the Forward (a “Placement Notice”), a form of which containing such minimum sales parameters necessary with respect to Issuances and Forwards is attached hereto as Exhibit A. The Placement Notice shall originate from any of the individuals from the Company set forth on Exhibit B (with a copy to each of the other individuals from the Company set forth on Exhibit B), and shall be addressed to each of the individuals from the applicable Agent or the applicable Forward Seller and Forward Purchaser set forth on Exhibit B (as such Exhibit B may be amended from time to time). In the case of a Forward, along with the Placement Notice, the Company shall deliver a duly executed Confirmation, with terms corresponding to such Placement.

(b) If an Agent or a Forward Seller and a Forward Purchaser, as applicable, wish to accept such proposed terms included in the Placement Notice and, in the case of a Forward, the Confirmation (which they may decline to do for any reason in their sole discretion) or, following discussion with the Company, wish to accept amended terms, such Agent or such Forward Seller and Forward Purchaser, as applicable, will, prior to 4:30 p.m. (New York City Time) on the business day following the business day on which such Placement Notice was delivered to such Agent or such Forward Seller and Forward Purchaser, as applicable, issue to the Company a notice by email (or other method mutually agreed to in writing by the parties) addressed to all of the individuals from the Company and such Agent or such Forward Seller and Forward Purchaser, as applicable, set forth on Exhibit B, setting forth the terms that such Agent or such Forward Seller and Forward Purchaser, as applicable, are willing to accept. Where the terms provided in the Placement Notice are amended as provided for in the immediately preceding sentence, such terms will not be binding on the Company or an Agent or a Forward Seller and Forward Purchaser, as applicable, until the Company delivers to such Agent or such Forward Seller and Forward Purchaser, as applicable, an acceptance by email (or other method mutually agreed to in writing by the parties) of all of the terms of such Placement Notice, as amended (an

“Acceptance”), which email shall be addressed to all of the individuals from the Company and such Agent or such Forward Seller and Forward Purchaser, as applicable, set forth on Exhibit B, along with, in the case of a Forward, a duly executed amended Confirmation, with terms corresponding to such Placement (as amended). The Placement Notice (as amended by the corresponding Acceptance, if applicable) shall be effective upon receipt by the Company of an Agent’s or a Forward Seller’s and Forward Purchaser’s, as applicable, acceptance of the terms of the Placement Notice or upon receipt by an Agent or a Forward Seller and Forward Purchaser, as applicable, of the Company’s Acceptance, as the case may be, unless and until (i) the entire amount of the Placement Shares has been sold, (ii) in accordance with the notice requirements set forth in the second sentence of the prior paragraph, the Company terminates the Placement Notice, (iii) the Company issues a subsequent Placement Notice with parameters superseding those on the earlier dated Placement Notice, (iv) this Agreement has been terminated pursuant to Section 13 or (v) any party shall have suspended the sale of the Placement Shares in accordance with Section 4. With respect to an Issuance, it is expressly acknowledged and agreed that neither the Company nor any Agent will have any obligation whatsoever with respect to a Placement or any Placement Shares unless and until the Company delivers a Placement Notice to an Agent and either (i) such Agent accepts the terms of such Placement Notice or (ii) where the terms of such Placement Notice are amended by such Agent, the Company accepts such amended terms by means of an Acceptance pursuant to the terms set forth above, and then only upon the terms specified in the Placement Notice (as amended by the corresponding Acceptance, if applicable) and herein. With respect to a Forward, it is expressly acknowledged and agreed that the Company, the applicable Forward Seller and Forward Purchaser will have no obligation whatsoever with respect to a Placement or any Placement Shares unless and until (i) the Company delivers a Placement Notice to such Forward Seller and Forward Purchaser and either (x) such Forward Seller and Forward Purchaser accept the terms of such Placement Notice or (y) where the terms of such Placement Notice are amended by such Forward Seller or Forward Purchaser, the Company accepts such amended terms by means of an Acceptance pursuant to the terms set forth above, and then only upon the terms specified in the Placement Notice (as amended by the corresponding Acceptance, if applicable), this Agreement and the applicable Confirmation, and (ii) the Forward Purchaser executes and delivers to the Company the applicable Confirmation. In the event of a conflict between the terms of this Agreement and the terms of a Placement Notice (as amended by the corresponding Acceptance, if applicable), the terms of the Placement Notice (as amended by the corresponding Acceptance, if applicable) will control.

(c) (i) No Placement Notice may be delivered hereunder other than on a Trading Day during the Commitment Period, (ii) no Placement Notice may be delivered hereunder if the Selling Period specified therein would overlap in whole or in part with any Selling Period specified in any other Placement Notice (as amended by the corresponding Acceptance, if applicable) delivered hereunder unless the Shares to be sold under all such previously delivered Placement Notices have all been sold, (iii) no Placement Notice may be delivered hereunder if any Selling Period specified therein would overlap in whole or in part with any Unwind Period under any Confirmation (as defined in such Confirmation) entered into between the Company and any Forward Purchaser and (iv) no Placement Notice specifying that it relates to a “Forward” may be delivered if such Placement Notice, together with all prior Placement Notices (as amended by the corresponding Acceptance, if applicable) delivered by the Company relating to a “Forward” hereunder, would result in the aggregate Capped Number under all Confirmations

entered into or to be entered into between the Company and the Forward Purchasers exceeding 19.99% of the number of shares of Common Stock outstanding as of the date of this Agreement.

(d) Notwithstanding any other provision of this Agreement, any notice required to be delivered by the Company or by an Agent (in the case of an Issuance) or a Forward Seller and Forward Purchaser (in the case of a Forward) pursuant to this Section 2 may be delivered by telephone (confirmed promptly by facsimile, email or other method mutually agreed to in writing by the parties, addressed to all of the individuals from the Company and such Agent (in the case of an Issuance) or such Forward Seller and Forward Purchaser (in the case of a Forward) set forth on Exhibit B (as such Exhibit B may be amended from time to time), which confirmation will be promptly acknowledged by the receiving party) or other method mutually agreed to in writing by the parties. For the avoidance of doubt, notices delivered by telephone shall originate from any of the individuals from the Company or an Agent (in the case of an Issuance) or a Forward Seller and a Forward Purchaser (in the case of a Forward) set forth on Exhibit B (as such Exhibit B may be amended from time to time).

SECTION 3. Sale of Shares.

The Agent will provide written confirmation by email (or other method mutually agreed to in writing by the parties) to all of the individuals from the Company set forth on Exhibit B (as such Exhibit B may be amended from time to time) no later than the opening of the Trading Day immediately following the Trading Day on which it has made sales of Issuance Shares hereunder setting forth the number of Issuance Shares sold on such day, the corresponding Sales Price, the compensation payable by the Company to such Agent pursuant to this Section 3(a) with respect to such sales, and the Net Proceeds (as defined in Section 6(b)) payable to the Company, with an itemization of the deductions made by the Agent (as set forth in Section 6(b)) from the Gross Proceeds (as defined in Section 6(b)) (prior to deductions for transaction fees) that it receives from such sales. The amount of any commission, discount or other compensation to be paid by the Company to an Agent, when such Agent is acting as agent, in connection with the sale of the Issuance Shares shall be determined in accordance with the terms set forth on Exhibit C. The amount of any commission, discount or other compensation to be paid by the Company to an Agent, when such Agent is acting as principal, in connection with the sale of the Shares shall be as separately agreed in writing among the relevant parties hereto at the time of any such sales.

(b) In addition, subject to the provisions of Section 6(d) and the applicable Confirmation, upon the delivery of a Placement Notice (as amended by the corresponding Acceptance, if applicable) specifying that it relates to a “Forward” and execution and delivery by the parties thereto of the applicable Confirmation, the applicable Forward Purchaser will use its commercially reasonable efforts to borrow or cause its affiliate to borrow, offer and sell Forward Hedge Shares through the applicable Forward Seller to hedge the Forward, and the applicable

Forward Seller will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Forward Hedge Shares at market prevailing prices up to the Forward Hedge Amount specified in such Placement Notice (as amended by the corresponding Acceptance, if applicable), and otherwise in accordance with the terms of such Placement Notice (as amended by the corresponding Acceptance, if applicable). Such Forward Seller will provide written confirmation by email (or other method mutually agreed to in writing by the parties) to all of the individuals from the Company set forth on Exhibit B (as such Exhibit B may be amended from time to time) and to the applicable Forward Purchaser no later than the opening of the Trading Day immediately following the Trading Day on which it has made sales of Forward Hedge Shares hereunder setting forth the number of Forward Hedge Shares sold on such day, the corresponding Sales Price and the Forward Hedge Price payable to such Forward Purchaser in respect thereof.

(c) Promptly following the completion of the Forward Hedge Selling Period, the applicable Forward Purchaser shall execute and deliver to the Company a Pricing Supplement (in the form set forth on Annex A to the applicable Confirmation), which shall set forth the initial “Number of Shares” for such Forward (which shall be the Actual Sold Forward Amount for such Forward Hedge Selling Period), the “Hedge Completion Date” for such Forward and the “Initial Forward Price” for such Forward.

(d) Notwithstanding anything herein to the contrary, any Forward Purchaser’s obligation to use its commercially reasonable efforts to borrow or cause its affiliate to borrow all or any portion of the Forward Hedge Shares (and the applicable Forward Seller’s obligation to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such portion of the Forward Hedge Shares) for any Forward hereunder shall be subject in all respects to the last paragraph of Section 4 of the applicable Confirmation.

(e) The Shares may be offered and sold by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 under the Securities Act, including without limitation sales made directly on the NYSE, on any other existing trading market for the Common Stock or to or through a market maker, or subject to the terms of the Placement Notice (as amended by the corresponding Acceptance, if applicable), any other method permitted by law, including but not limited to, privately negotiated transactions.

(f) If the Company or any Agent has reason to believe that 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, it shall promptly notify the other parties, and sales of Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of all parties.

SECTION 4. Suspension of Sales. The Company, an Agent or a Forward Seller or Forward Purchaser may, upon notice to the other parties in writing (including by email correspondence or other method mutually agreed to in writing by the parties) to each of the individuals of the other party set forth on Exhibit B (as such Exhibit B may be amended from time to time), if receipt of such correspondence is actually acknowledged by any of the individuals to whom the notice is sent, other than via auto-reply, or by telephone (confirmed

immediately by verifiable facsimile transmission, email correspondence or other method mutually agreed to in writing by the parties) to each of the individuals of the other party set forth on Exhibit B (as such Exhibit B may be amended from time to time), suspend any sale of Shares, and the applicable Selling Period shall immediately terminate; provided, however, that such suspension and termination shall not affect or impair any party’s obligations with respect to any Shares sold hereunder prior to the receipt of such notice (and, in the case of any Forward Hedge Shares, the resulting Confirmation). The Company agrees that no such notice shall be effective against an Agent, a Forward Seller or a Forward Purchaser unless it is made to one of the individuals named on Exhibit B (as such Exhibit B may be amended from time to time); provided, however, that the failure by the Company to deliver such notice shall in no way affect its right to suspend the sale of Shares hereunder. Each of the Agents, the Forward Sellers and the Forward Purchasers agree that no such notice shall be effective against the Company unless it is made to one of the individuals named on Exhibit B (as such Exhibit B may be amended from time to time); provided, however, that the failure by an Agent, a Forward Seller or a Forward Purchaser to deliver such notice shall in no way effect such party’s right to suspend the sale of Shares hereunder.

SECTION 5. Representations and Warranties.

(a) Representations and Warranties of the Company. The Company represents and warrants to each Agent, each Forward Seller and each Forward Purchaser as of the date hereof, as of each Representation Date (as defined below) on which a certificate is required to be delivered pursuant to Section 7(o) of this Agreement, as of each Applicable Time and as of each Settlement Date, and agrees with each Agent, each Forward Seller and each Forward Purchaser, as follows:

The representations and warranties set forth in the immediately preceding paragraph shall not apply to statements in or omissions from the Registration Statement or the Prospectus, as amended or supplemented, made in reliance upon and in conformity with information furnished to the Company in writing by the Agents, the Forward Sellers or the Forward Purchasers expressly for use therein. For purposes of this Agreement, the only information so furnished shall be the legal and/or marketing names of the Agents, the Forward Sellers and the Forward Purchasers appearing on the front cover page of the Prospectus.

Each Issuer Free Writing Prospectus relating to the Shares specified on Exhibit F, as of its date, as of the date hereof, as of each Applicable Time and as of each Settlement Date, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any incorporated document deemed to be a part thereof, that has not been superseded or modified, or included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in light of the circumstances, prevailing at that subsequent time, not misleading.

At (i)(a) the time of the initial filing of the Registration Statement, (b) the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of

SECTION 6. Sale and Delivery; Settlement.

(a) Sale of Issuance Shares. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, upon an Agent’s acceptance of the terms of a Placement Notice specifying that it relates to an “Issuance” or upon receipt by an Agent of an Acceptance, as the case may be, and unless the sale of the Issuance Shares described therein has been declined, suspended, or otherwise terminated in accordance with the terms of this Agreement, such Agent will, for the period specified in such Placement Notice (as amended by the corresponding Acceptance, if applicable), use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Issuance Shares at market prevailing prices up to the amount specified, and otherwise in accordance with the terms of such Placement Notice (as amended by the corresponding Acceptance, if applicable). The Company acknowledges and agrees that (i) there can be no assurance that any Agent will be successful in selling Issuance Shares, (ii) no Agent will incur any liability or obligation to the Company or any other person or entity if it does not sell Issuance Shares for any reason other than a failure by

such Agent to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Issuance Shares as required under this Section 6 and (iii) no Agent shall be under any obligation to purchase Issuance Shares on a principal basis pursuant to this Agreement, except as otherwise agreed by such Agent in a Placement Notice (as amended by the corresponding Acceptance, if applicable) and subject to Section 1 hereof.

(b) Settlement of Issuance Shares. On each Issuance Settlement Date, the Issuance Shares sold through an Agent for settlement on such date shall be delivered by the Company to such Agent against payment of (i) the Net Proceeds from the sale of such Issuance Shares or (ii) as mutually agreed between the Company and such Agent, the Gross Proceeds from the sale of such Issuance Shares. The gross proceeds to the Company (the “Gross Proceeds”) shall be equal to the aggregate offering price received by an Agent at which such Issuance Shares were sold, after deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales. The net proceeds to the Company (the “Net Proceeds”) shall be equal to the Gross Proceeds less such Agent’s commission, discount or other compensation payable by the Company pursuant to Section 3 and any other amounts due and payable by the Company to such Agent hereunder pursuant to Section 8(a). In the event the Company and an Agent have mutually agreed to the delivery of Gross Proceeds at an Issuance Settlement Date, such Agent’s commission, discount or other compensation for such sales payable by the Company pursuant to Section 3 hereof and any other amounts due and payable by the Company to such Agent hereunder pursuant to Section 8(a) shall be set forth and invoiced in a periodic statement from such Agent to the Company, payment to be made by the Company promptly after its receipt thereof.

(c) Delivery of Issuance Shares. On or before each Issuance Settlement Date, the Company will, or will cause its transfer agent to, electronically transfer the Issuance Shares being sold by crediting the applicable Agent’s or its designee’s account (provided such Agent shall have given the Company written notice of such designee prior to the Issuance Settlement Date) at The Depository Trust Company through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the relevant parties hereto which in all cases shall be freely tradable, transferable, registered shares in good deliverable form. On each Issuance Settlement Date, the applicable Agent will deliver the related Net Proceeds or Gross Proceeds, as applicable, in same day funds to an account designated by the Company prior to the Issuance Settlement Date. The Company agrees that if the Company, or its transfer agent (if applicable), defaults in its obligation to deliver Issuance Shares on an Issuance Settlement Date, the Company, in addition to and in no way limiting the rights and obligations set forth in Section 10 and Section 11, will (i) hold such Agent harmless against any loss, liability, claim, damage, or expense whatsoever (including reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by the Company or its transfer agent (if applicable) and (ii) pay to such Agent any commission, discount, or other compensation to which it would otherwise have been entitled absent such default.

(d) Sale of Forward Hedge Shares. On the basis of the representations and warranties herein contained and subject to the terms and conditions in this Agreement and the Confirmation, upon a Forward Purchaser and Forward Seller’s acceptance of the terms of a Placement Notice specifying that it relates to a “Forward” or upon receipt by a Forward Purchaser and Forward Seller of an Acceptance, as the case may be, and execution and delivery by all relevant parties of

the related Confirmation, and unless the sale of the Forward Hedge Shares described therein has been declined, suspended, or otherwise terminated in accordance with the terms of this Agreement or such Confirmation, such Forward Purchaser will use its commercially reasonable efforts to borrow or cause its affiliate to borrow a number of Forward Hedge Shares sufficient to have an aggregate Sales Price as close as reasonably practicable to the Forward Hedge Amount specified in the Placement Notice (as amended by the corresponding Acceptance, if applicable) and the applicable Forward Seller will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Forward Hedge Shares at market prevailing prices, and otherwise in accordance with the terms of such Placement Notice (as amended by the corresponding Acceptance, if applicable). Each of the Company and the Forward Purchasers acknowledges and agrees that (i) there can be no assurance that any Forward Purchaser or its affiliate will be successful in borrowing or that any Forward Seller will be successful in selling Forward Hedge Shares, (ii) no Forward Seller will incur any liability or obligation to the Company, any Forward Purchaser, or any other person or entity if it does not sell Forward Hedge Shares borrowed by such Forward Purchaser or its affiliate for any reason other than a failure by such Forward Seller to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Forward Hedge Shares as required under this Section 6, and (iii) no Forward Purchaser will incur any liability or obligation to the Company, the Forward Seller, or any other person or entity if it or its affiliate does not borrow Forward Hedge Shares for any reason other than a failure by such Forward Purchaser to use its commercially reasonable efforts to borrow or cause its affiliate to borrow such Forward Hedge Shares as required under this Section 6. In acting hereunder, each Forward Seller will be acting as an agent for the applicable Forward Purchaser and not as principal.

(e) Delivery of Forward Hedge Shares. On or before each Forward Hedge Settlement Date, the applicable Forward Purchaser will, or will cause its transfer agent to, electronically transfer the Forward Hedge Shares being sold by crediting the applicable Forward Seller or its designee’s account (provided such Forward Seller shall have given the applicable Forward Purchaser written notice of such designee prior to the Forward Hedge Settlement Date) at The Depository Trust Company through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties hereto which in all cases shall be freely tradable, transferable, registered shares in good deliverable form. On each Forward Hedge Settlement Date, the applicable Forward Seller will deliver the related aggregate Forward Hedge Price to the applicable Forward Purchaser in same day funds to an account designated by such Forward Purchaser prior to the relevant Forward Hedge Settlement Date.

(f) Denominations; Registration. The Shares shall be in such denominations and registered in such names as an Agent or a Forward Seller, as applicable, may request in writing at least one full business day before the Settlement Date. The Company or a Forward Purchaser, as applicable, shall deliver the Shares, if any, through the facilities of The Depository Trust Company as described in the preceding paragraphs unless such Agent or such Forward Seller, as applicable, shall otherwise instruct.

(g) Limitations on Offering Size. Under no circumstances shall the Company cause or request the offer or sale of any Shares if, after giving effect to the sale of such Shares, the aggregate offering price of the Shares sold pursuant to this Agreement would exceed the lesser of (i) the Maximum Amount, (ii) the amount available for offer and sale under the currently

effective Registration Statement, or (iii) the amount authorized from time to time to be issued and sold under this Agreement by the Board of Directors of the Company or a duly authorized committee thereof. Under no circumstances shall the Company cause or request the offer or sale of any Shares pursuant to this Agreement at a price lower than the minimum price authorized from time to time by the Board of Directors of the Company and notified to an Agent or a Forward Seller, as applicable, in writing.

(h) Limitations on Agents and Forward Sellers. The Company agrees that any offer to sell, any solicitation of an offer to buy or any sales of Shares or any other equity security of the Company shall only be effected by or through one Agent or Forward Seller, as the case may be, on any single given day, but in no event more than one, and the Company shall in no event request that more than one Agent or Forward Seller, as the case may be, sell Shares on the same day; provided, however, that (a) the foregoing limitation shall not apply to (i) the exercise of any option, warrant, right or any conversion privilege set forth in the instrument governing such security or (ii) sales solely to employees, directors or security holders of the Company or its subsidiaries, or to a trustee or other person acquiring such Shares for the accounts of such persons, (b) such limitation shall not apply on any day during which no sales are made pursuant to this Agreement, and (c) such limitation shall not apply if, prior to any such request to sell Shares, all Shares the Company has previously requested the Agents or the Forward Sellers to sell have been sold.

(i) Certain Blackout Periods. Notwithstanding any other provision of this Agreement, the Company shall not offer, sell or deliver, or request the offer or sale of, any Shares and, by notice to an Agent (in the case of an Issuance) or a Forward Seller and Forward Purchaser (in the case of a Forward) given by telephone (confirmed promptly by facsimile transmission, email or other method mutually agreed to in writing by the parties), shall cancel any instructions for the offer or sale of any Shares, and no Agent, Forward Seller or Forward Purchaser, as the case may be, shall be obligated to offer or sell any Shares (i) during the period beginning on the 10th business day after the end of each calendar quarter through and including the first date (each, an “Announcement Date”) on which the Company shall issue a press release containing, or shall otherwise publicly announce, its earnings or revenue results for a completed fiscal year or quarter (each, an “Earnings Announcement”), (ii) except as provided in Section 6(j) below, at any time from and including an Announcement Date through and including the time that the Company files (a “Filing Time”) 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 period or periods, as the case may be, covered by such Earnings Announcement, or (iii) during any other period in which the Company is in possession of material non-public information; provided that, unless otherwise agreed between the Company and an Agent, a Forward Seller or a Forward Purchaser, as the case may be, for purposes of (i) and (ii) above, such period shall be deemed to end at the relevant Filing Time.

(j) Filing of Earnings 8-K. If the Company wishes to offer, sell or deliver Shares at any time during the period from and including an Announcement Date through and including the corresponding Filing Time, the Company shall (i) prepare and deliver to the Agents (in the case of an Issuance) or the Forward Sellers and Forward Purchasers (in the case of a Forward) (with a copy to their respective counsel) a Current Report on Form 8-K which shall include substantially the same financial and related information as was set forth in the relevant Earnings

Announcement (other than any earnings projections, similar forward-looking data and officers’ quotations) (each, an “Earnings 8-K”), in form and substance reasonably satisfactory to the Agents or the Forward Sellers and Forward Purchasers, as the case may be, and obtain the consent of the Agents or the Forward Sellers and Forward Purchasers, as the case may be, to the filing thereof (such consent not to be unreasonably withheld); (ii) provide the Agents or the Forward Sellers and Forward Purchasers, as the case may be, with the officers’ certificate, opinions/letters of counsel and accountants’ letter called for by Sections 7(o), (p) and (q) hereof, respectively; (iii) afford the Agents or the Forward Sellers and the Forward Purchasers, as the case may be, the opportunity to conduct a due diligence review in accordance with Section 7(m) hereof; and (iv) file such Earnings 8-K with the Commission. The provisions of clause (ii) of Section 6(i) shall not be applicable for the period from and after the time at which the foregoing conditions shall have been satisfied (or, if later, the time that is 24 hours after the time that the relevant Earnings Announcement was first publicly released) through and including the Filing Time of the relevant Quarterly Report on Form 10-Q or Annual Report on Form 10-K under the Exchange Act, as the case may be. For purposes of clarity, the parties hereto agree that (A) the delivery of any officers’ certificate, opinions/letters of counsel and accountants’ letter pursuant to this Section 6(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/letters of counsel and accountants’ letters as provided in Sections 7(o), (p) and (q) hereof and (B) other than as set forth in this Section 6(j), this Section 6(j) shall in no way affect or limit the operation of the provisions of clauses (i) and (iii) of Section 6(i), which shall have independent application.

SECTION 7. Covenants of the Company. The Company covenants with each of the Agents, the Forward Sellers and the Forward Purchasers as follows:

(a) The Company will not file any amendment or supplement to the Registration Statement or Prospectus, other than documents incorporated by reference, unless a copy thereof has been submitted to the Agents, the Forward Sellers and the Forward Purchasers within a reasonable period of time before the filing and the Agents, the Forward Sellers and the Forward Purchasers have not reasonably objected thereto (provided, however, that the failure of the Agents, the Forward Sellers or the Forward Purchasers to make such objection shall not relieve the Company of any obligation or liability hereunder, or affect the Agents’, the Forward Sellers’ or the Forward Purchasers’ right to rely on the representations and warranties made by the Company in this Agreement) and the Company will promptly notify the Agents, the Forward Sellers and the Forward Purchasers when any such filing has been made or become effective, as applicable, and furnish to the Agents, the Forward Sellers and the Forward Purchasers at the time of filing thereof a copy of any document that upon filing is deemed to be incorporated by reference into the Registration Statement or Prospectus, except for those documents available via XXXXX. The Company will cause each amendment or supplement to the Prospectus, other than documents incorporated by reference or an amendment or supplement relating solely to the issuance or offering of securities other than the Shares, to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) under the Securities Act (without reliance on Rule 424(b)(8) under the Securities Act).

(b) The Company will advise the Agents, the Forward Sellers and the Forward Purchasers promptly of the institution by the Commission of any stop order proceedings in respect of the Registration Statement or any proceedings pursuant to Section 8A of the Securities Act, and will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(c) The Company will furnish to the Agents, the Forward Sellers and the Forward Purchasers, without charge, copies of the Registration Statement (which will include all exhibits other than those incorporated by reference), the Prospectus, any Issuer Free Writing Prospectuses, and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Agents, the Forward Sellers and the Forward Purchasers may reasonably request.

(d) The Company, during any period when a prospectus relating to the Shares is required to be delivered under the Securities Act, will timely file all documents required to be filed with the Commission pursuant to Section 13 or 14 of the Exchange Act. If at any time when a prospectus relating to the Shares (or the notice referred to in Rule 173(a) under the Securities Act) is required to be delivered under the Securities Act any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact, or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Prospectus to comply with the Securities Act, the Company will prepare and file with the Commission an amendment, supplement or an appropriate document pursuant to Section 13 or 14 of the Exchange Act which will correct such statement or omission or which will effect such compliance.

(e) Without the prior consent of the Agents, the Forward Sellers and the Forward Purchasers, the Company has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act, other than an Issuer Free Writing Prospectus; each Agent, Forward Seller and Forward Purchaser, severally and not jointly, represents and agrees that, without the prior consent of the Company, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act, other than an Issuer Free Writing Prospectus or a free writing prospectus that is not required to be filed by the Company pursuant to Rule 433 under the Securities Act; any such free writing prospectus, the use of which has been consented to by the Company and the Agents, the Forward Sellers and the Forward Purchasers, is listed herein on Exhibit F.

(f) The Company represents that it has treated or agrees that it will treat each Issuer Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, and has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping. The Company agrees that if at any time following the issuance of an Issuer Free Writing Prospectus or any electronic roadshow or other written communication that constitutes an offer to buy the Shares provided to investors by, or with the approval of, the Company, any event occurs as a result of which such Issuer Free Writing Prospectus or such electronic roadshow or other written communication would conflict

with the information in the Registration Statement or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Agents, the Forward Sellers and the Forward Purchasers, and, if requested by the Agents, the Forward Sellers and the Forward Purchasers, will prepare and furnish without charge to each Agent, Forward Seller and Forward Purchaser a free writing prospectus or other document, the use of which has been consented to by the Agents, which will correct such conflict, statement or omission.

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

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

(i) The Company will use the net proceeds received by it from the sale of the Shares in the manner specified in the Prospectus under “Use of Proceeds.”

(j) During any Selling Period or period in which the Prospectus relating to the Shares is required by the Securities Act to be delivered in connection with a pending sale of the Shares (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act), the Company will use its commercially reasonable efforts to cause the Shares to be listed on the NYSE.

(k) The Company, during any period when the Prospectus is required to be delivered under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act), will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act.

(l) The Company will, at any time during a fiscal quarter in which the Company intends to tender a Placement Notice or sell Shares, advise the Agents, Forward Sellers and Forward Purchasers promptly after it shall have received notice or obtained knowledge, of any information or fact that would alter or affect in any material respect any opinion, certificate, letter or other document provided to the Agents, the Forward Sellers or the Forward Purchasers, as applicable, pursuant to this Agreement.

(m) The Company will cooperate with any due diligence review reasonably requested by the Agents or the Forward Sellers and Forward Purchasers, as applicable, in connection with the transactions contemplated hereby, including, without limitation, and upon reasonable notice, providing information and making available documents and appropriate corporate officers, during regular business hours and at the Company’s principal offices, as the Agents, Forward Sellers and Forward Purchasers may reasonably request.

(n) The Company will disclose in its Quarterly Reports on Form 10-Q and in its Annual Reports on Form 10-K the number of Shares sold pursuant to this Agreement and the Net Proceeds to the Company, together with any other information that the Company reasonably believes is required to comply with the Securities Act and the Exchange Act.

(o) (1) each time the Company:

(i) files the Prospectus relating to the Shares or amends or supplements the Registration Statement or the Prospectus relating to the Shares by means of a post-effective amendment, sticker, or supplement but not by means of incorporation of documents by reference into the Registration Statement or the Prospectus relating to the Shares;

(ii) files an Annual Report on Form 10-K under the Exchange Act;

(iii) files a Quarterly Report on Form 10-Q under the Exchange Act; or

(iv) files a Current Report on Form 8-K that contains financial statements or pro forma financial statements required under Item 2.01 or Item 4.02 or files financial statements or pro forma financial statements or pro forma financial information under Item 9.01 of Form 8-K; and

(2) at any other time reasonably requested by the Agents, the Forward Sellers or the Forward Purchasers (each such date of filing of one or more of the documents referred to in clauses (1)(i) through (iv) above and any time of request pursuant to this Section 7(o) shall be a “Representation Date”),

the Company shall furnish the Agents, the Forward Sellers and the Forward Purchasers with a certificate in the form attached hereto as Exhibit E. The requirement to provide a certificate under this Section 7(o) shall be waived (i) on the date of this Agreement and (ii) for any Representation Date occurring at a time at which no Placement Notice (as amended by the corresponding Acceptance, if applicable) is pending, which waiver shall continue until the earlier to occur of the date the Company delivers a Placement Notice hereunder (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date; provided, however, that such waiver shall not apply for any Representation Date on which the Company files its Annual Report on Form 10-K. Notwithstanding the foregoing, if the Company subsequently decides to sell Shares following a Representation Date when the Company relied on such waiver and did not provide the Agents with a certificate under this Section 7(o), then before the Company delivers the Placement Notice or any Agent or Forward Seller sells any Shares, the

Company shall provide the Agents, the Forward Sellers and the Forward Purchasers with a certificate, in the form attached hereto as Exhibit E, dated the date such certificate is delivered.

(p) The Company shall cause to be furnished to the Agents, the Forward Sellers and the Forward Purchasers (A) on the date of this Agreement, a written opinion of Hunton & Xxxxxxxx LLP (“Company Counsel”), or other counsel satisfactory to the Agents, the Forward Sellers and the Forward Purchasers, in form and substance satisfactory to the Agents, the Forward Sellers and the Forward Purchasers and their counsel, dated the date that the opinion is required to be delivered, substantially similar to the form attached hereto as Exhibit D-1 and (B) on each Representation Date with respect to which the Company is obligated to deliver a certificate in the form attached hereto as Exhibit E for which no waiver is applicable, (i) a written opinion and, if not covered in such opinion, a negative assurance letter, of Company Counsel, or other counsel satisfactory to the Agents, the Forward Sellers and the Forward Purchasers, in form and substance satisfactory to the Agents, the Forward Sellers and the Forward Purchasers and their counsel, dated the date that the opinion is required to be delivered, substantially similar to the form attached hereto as Exhibit D-2 and (ii) a written opinion of Xxxxxx X. Xxxxx III, Esq., Deputy General Counsel of Duke Energy Business Services LLC, a service company subsidiary of the Company (“Deputy General Counsel”), or other counsel satisfactory to the Agents, the Forward Sellers and the Forward Purchasers, in form and substance satisfactory to the Agents, the Forward Sellers and the Forward Purchasers and their counsel, dated the date that the opinion is required to be delivered, substantially similar to the form attached hereto as Exhibit D-3; in each case, modified as necessary to relate to the Registration Statement and the Prospectus as then amended or supplemented; provided, however, that in lieu of such opinions for subsequent Representation Dates, Company Counsel and Deputy General Counsel may each furnish the Agents, the Forward Sellers and the Forward Purchasers with a reliance letter to the effect that the Agents, the Forward Sellers and the Forward Purchasers may rely on a prior opinion delivered under this Section 7(p)(B) to the same extent as if it were dated the date of such letter (except that statements in such prior opinion shall be deemed to relate to the Registration Statement and the Prospectus as amended or supplemented at such Representation Date).

(q) On each Representation Date with respect to which the Company is obligated to deliver a certificate in the form attached hereto as Exhibit E for which no waiver is applicable, the Company shall cause its independent accountants (and any other independent accountants whose report is included in the Registration Statement or the Prospectus) to furnish the Agents, the Forward Sellers and the Forward Purchasers a letter (the “Comfort Letter”), dated the date the Comfort Letter is delivered, in form and substance satisfactory to the Agents, the Forward Sellers and the Forward Purchasers (i) confirming that they are an independent registered public accounting firm within the meaning of the Securities Act, the Exchange Act and the Public Company Accounting Oversight Board and (ii) stating, as of such date, the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings.

(r) On each Representation Date with respect to which the Company is obligated to deliver a certificate in the form attached hereto as Exhibit E for which no waiver is applicable, the Agents, the Forward Sellers and the Forward Purchasers shall have received the favorable

written opinion or opinions of Sidley Austin LLP, counsel for the Agents, the Forward Sellers and the Forward Purchasers, dated such date, with respect to such matters as the Agents, the Forward Sellers and the Forward Purchasers may reasonably request.

(s) The Company will not, directly or indirectly, (i) take any action designed to cause or result in, or that constitutes or might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares or (ii) sell, bid for, or purchase the Shares to be issued and sold pursuant to this Agreement, or pay anyone any compensation for soliciting purchases of the Shares to be issued and sold pursuant to this Agreement other than the Agents and the Forward Sellers; provided, however, that the Company may bid for and purchase its Common Stock in accordance with Rule 10b-18 under the Exchange Act; and provided further, that no such bids or purchases shall be made by the Company during the two (2) Trading Days before or after any sale of any Shares pursuant to this Agreement.

(t) The Company consents to the Agents or the Forward Sellers, as applicable, 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.

(u) Other than a “free writing prospectus” (as defined in Rule 405 under the Securities Act) approved in advance in writing by the Company and the Agents in their capacity as principals or agents hereunder or the Forward Sellers in their capacity as agents hereunder, the Company (including its agents and representatives, other than the Agents in their capacity as such) will not, directly or indirectly, make, use, prepare, authorize, approve or refer to any free writing prospectus relating to the Shares to be sold by the Agents or the Forward Sellers as principals or agents hereunder.

(v) The Company shall reserve and keep available at all times, free of pre-emptive rights, Shares for the purpose of enabling the Company to satisfy its obligations under this Agreement and each Confirmation.

(w) In connection with entering into any Forward, neither the Company nor any of its affiliates will acquire any long position (either directly or indirectly, including through a derivative transaction) with respect to shares of Common Stock.

(x) If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Shares remain unsold by the Agents, the Company will, prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Shares, in a form reasonably satisfactory to the Agents. If the Company is not eligible to file an automatic shelf registration statement, the Company will, prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Shares, in a form reasonably satisfactory to the Agents, and will use its commercially reasonable efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Shares to continue as contemplated in the expired registration statement. References

herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

of such Placement Notice (as amended by the corresponding Acceptance, if applicable) and the obligation of a Forward Purchaser to use its commercially reasonable efforts to borrow or cause its affiliate to borrow Forward Hedge Shares in connection with a Placement Notice (as amended by the corresponding Acceptance, if applicable) are subject to the continuing accuracy of the representations and warranties of the Company contained in this Agreement or certificates of any officer of the Company delivered pursuant to the provisions hereof, the performance by the Company of its covenants and obligations hereunder, and the satisfaction, on the applicable Settlement Date, of each of the following conditions, except to the extent waived by the applicable Agent, Forward Seller and Forward Purchaser, in its sole discretion:

(2) None of the following events shall have occurred and be continuing: (i) receipt by the Company or any of its subsidiaries of any request for additional information from the Commission or any other federal or state governmental authority during the period of effectiveness of the Registration Statement, the response to which would require any post-effective amendments or supplements to the Registration Statement or the Prospectus; (ii) the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose or pursuant to Section 8A of the Securities Act; (iii) receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of the Common Stock for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; (iv) the occurrence of any event that makes any material statement made in the Registration Statement or the Prospectus, or any Issuer Free Writing Prospectus, or any material document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in the Registration Statement, related Prospectus, or any Issuer Free Writing Prospectus, or such documents so that, in the case of the Registration Statement, it will not contain any materially untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, that in the case of the Prospectus and any Issuer Free Writing Prospectus, it will not contain any materially untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(3) None of the Agents, the Forward Sellers or the Forward Purchasers shall have advised the Company that the Registration Statement or Prospectus, or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, contains an untrue statement of fact that in such Agent’s, Forward Seller’s or Forward Purchaser’s reasonable opinion is material, or omits to state a fact that in such Agent’s, Forward Seller’s or Forward Purchaser’s opinion is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(4) Except as contemplated in the Prospectus, or disclosed in the Company’s reports filed with the Commission, there shall not have been any material adverse change in the condition of the Company, financial or otherwise, and except as reflected in or contemplated by the Prospectus, or disclosed in the Company’s reports filed with the Commission, and, since the date of such disclosure, there shall not have been any material transaction entered into by the Company other than transactions contemplated by the Prospectus, or disclosed in the Company’s reports filed with the Commission, and transactions in the ordinary course of business, the effect of which in your reasonable judgment is so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares on the terms and in the manner contemplated by the Prospectus.

(5) The Agents, the Forward Sellers and the Forward Purchasers shall have received the favorable opinions of Company Counsel and Deputy General Counsel, required to be delivered pursuant to Section 7(p) on the date on which such delivery of such opinion is required pursuant to Section 7(p).

(6) The Agents, the Forward Sellers and the Forward Purchasers shall have received the favorable opinions of Sidley Austin LLP, counsel to the Agents, the Forward Sellers and the Forward Purchasers, required to be delivered pursuant to Section 7(r) on the date on which such delivery of such opinion is required pursuant to Section 7(r).

(7) The Agents, the Forward Sellers and the Forward Purchasers shall have received the certificate required to be delivered pursuant to Section 7(o) on the date on which delivery of such certificate is required pursuant to Section 7(o).

(8) The Agents, the Forward Sellers and the Forward Purchasers shall have received the Comfort Letter required to be delivered pursuant Section 7(q) on the date on which such delivery of such opinion is required pursuant to Section 7(q).

(9) The Shares shall either have been (i) approved for listing on the NYSE, subject only to notice of issuance, or (ii) the Company shall have filed an application for listing of the Shares on the NYSE at, or prior to, the issuance of any Placement Notice.

(10) Trading in the Shares shall not have been suspended on the NYSE.

(11) On each date on which the Company is required to deliver a certificate pursuant to Section 7(o), counsel for the Agents, the Forward Sellers and the Forward Purchasers shall have been furnished with such

documents as they may require for the purpose of enabling them to issue the opinion required to be delivered pursuant to Section 7(r), or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, contained in this Agreement.

(12) All filings with the Commission required by Rule 424 under the Securities Act to have been filed prior to the issuance of any Placement Notice hereunder shall have been made within the applicable time period prescribed for such filing by Rule 424 under the Securities Act.

(13) In no event may the Company issue a Placement Notice to sell an Issuance Amount or a Forward Hedge Amount, as the case may be, to the extent that the sum of (i) the Sales Price of the requested Issuance Amount or Forward Hedge Amount, as applicable, plus (ii) the aggregate Sales Price of all Shares issued under all previous Issuances and Forwards effected pursuant to this Agreement would exceed the Maximum Amount.

(b) Termination of Agreement. If any condition specified in this Section 9 shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by any Agent, Forward Seller or Forward Purchaser by written notice to the Company, and such termination shall be without liability of any party to any other party except as provided in Section 8 hereof and except that, in the case of any termination of this Agreement, Sections 5, 10, 11, 12 and 15 hereof shall survive such termination and remain in full force and effect.

SECTION 10. Indemnification.

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each of the Agents, the Forward Sellers and the Forward Purchasers, their respective affiliates, officers and directors, and each person, if any, who controls any of the Agents, the Forward Sellers or the Forward Purchasers (the “Indemnified Parties”) within the meaning of Section 15 of the Securities Act, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any electronic roadshow or other written communication that constitutes an offer to buy the Shares provided to investors by, or with the approval of, the Company, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, unless such statement or omission or such alleged statement or omission was made in reliance upon and in conformity with written

information furnished to the Company by the Agents, the Forward Purchasers or the Forward Sellers expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto);

(ii) against any and all loss, liability, claim, damage and expense whatsoever to the extent of the aggregate amount paid in settlement of any litigation, commenced or threatened, or of any claim whatsoever arising out of or based upon any such untrue statement or omission or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever reasonably incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) of this Section 10.

In no case shall the Company be liable under this indemnity agreement with respect to any claim made against any Indemnified Party unless the Company shall be notified in writing of the nature of the claim within a reasonable time after the assertion thereof, but failure to so notify the Company shall not relieve it from any liability which it may have otherwise than under this Section 10(a). The Company shall be entitled to participate at its own expense in the defense, or, if it so elects, within a reasonable time after receipt of such notice, to assume the defense of any suit brought to enforce any such claim, but if it so elects to assume the defense, such defense shall be conducted by counsel chosen by it and approved by the applicable Indemnified Party or Parties in any suit so brought, which approval shall not be unreasonably withheld. In any such suit, any Indemnified Party shall have the right to employ its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Company and such Indemnified Party shall have mutually agreed to the employment of such counsel, or (ii) the named parties to any such action (including any impleaded parties) include both such Indemnified Party and the Company and such Indemnified Party shall have been advised by such counsel that a conflict of interest between the Company and such Indemnified Party may arise and for this reason it is not desirable for the same counsel to represent both the indemnifying party and also the indemnified party (it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for all such Indemnified Parties, which firm shall be designated in writing by you). The Company agrees to notify you within a reasonable time of the assertion of any claim against it, any of its officers or directors or any person who controls the Company within the meaning of Section 15 of the Securities Act, in connection with the sale of the Shares.

(b) (i) Each Agent, Forward Seller and Forward Purchaser, severally and not jointly, agrees that it will indemnify and hold harmless the Company, its directors and each of the officers of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act to the same extent as the indemnity contained in Section 10(a), but only with respect to

statements or omissions made in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Agents, the Forward Sellers or Forward Purchasers expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto). In case any action shall be brought against the Company or any person so indemnified based on the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto) and in respect of which indemnity may be sought against any Agent, Forward Seller or Forward Purchaser, such Agent, Forward Seller or Forward Purchaser shall have the rights and duties given to the Company, and the Company and each person so indemnified shall have the rights and duties given to the Agents, the Forward Sellers and the Forward Purchasers and the affiliates, officers, directors and controlling persons by the provisions of Section 10(a).

(ii) No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

SECTION 11. Contribution. If the indemnification provided for in Section 10 is unavailable to or insufficient to hold harmless an indemnified party in respect of any and all loss, liability, claim, damage and expense whatsoever (or actions in respect thereof) that would otherwise have been indemnified under the terms of such indemnity, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the relevant Agent, Forward Seller and Forward Purchaser, 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 above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and the relevant Agent, Forward Seller and Forward Purchaser, on the other, in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the relevant Agent, Forward Seller and Forward Purchaser, on the other, shall be deemed to be in the same proportions as (a) in the case of the Company, (x) the total net proceeds from the offering of the Issuance Shares for each Issuance under this Agreement (before deducting expenses) received by the Company, bear to the aggregate Sales Price of the Issuance Shares, or (y) the Actual Sold Forward Amount for each Forward under this Agreement, multiplied by the Forward Hedge Price for such Forward (the “Net Forward Proceeds”), bear to the sum of the Net Forward Proceeds and the Actual Forward Commission (as defined below) (such sum, the “Gross Forward Amount”), (b) in the case of the Agents, the

total commissions received by the Agents, bear to the aggregate Sales Price of the Issuance Shares, (c) in the case of the Forward Sellers, the Actual Sold Forward Amount for each Forward under this Agreement, multiplied by the Forward Hedge Selling Commission for such Forward (the “Actual Forward Commission”), bear to the Gross Forward Amount, and (d) in the case of the Forward Purchasers, the net Spread (as such term is defined in the related Confirmation for each Forward and net of any related stock borrow costs or other costs or expenses actually incurred) for each Confirmation executed in connection with this Agreement, bear to the Gross Forward Amount. 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, the Forward Sellers and the 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, the Forward Sellers and the Forward Purchasers agree that it would not be just and equitable if contributions pursuant to this Section were determined by pro rata allocation (even if the Agents, the Forward Sellers 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 Section 11. The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to above in this Section shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 11, (i) no Agent or Forward Seller shall in any event be required to contribute any amount in excess of the amount by which the commissions with respect to the offering of the Issuance Shares or the aggregate Forward Hedge Selling Commissions, as the case may be, received by it under this Agreement exceeds the amount of any damages which such Agent or Forward Seller has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and (ii) the Forward Purchaser shall in no event be required to contribute any amount in excess of the amount by which the net Spread (as such term is defined in the Confirmations and net of any related stock borrow costs or other costs or expenses actually incurred) for all Confirmations entered into pursuant to this Agreement exceeds the amount of any damages such Forward Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omissions 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 Agents’, the Forward Sellers’ and the Forward Purchasers’ obligations to contribute are several in proportion to their respective obligations and not joint.

SECTION 12. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers or other representatives 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 the Agents, the Forward Sellers, the Forward Purchasers or any their respective affiliates, officers and directors, and each person, if any, who controls any of the Agents, the Forward Sellers or the Forward Purchasers, or by or on behalf of the Company or its directors, each of the Company’s officers who signed the Registration Statement, and each

person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, (ii) delivery and acceptance of the Shares and payment therefor, (iii) the settlement of any Confirmations or (iv) any termination of this Agreement or any Confirmations.

SECTION 13. Termination of Agreement.

(a) Termination; General. Each Agent, Forward Seller or Forward Purchaser may terminate the right of the Company to effect any Issuances or Forwards under this Agreement, solely with respect to such Agent, Forward Seller or Forward Purchaser, by notice to the Company, as hereinafter specified at any time if there has been (i) a suspension or material limitation in trading in securities generally or of the securities of the Company, on the New York Stock Exchange; or (ii) a general moratorium on commercial banking activities in New York declared by either Federal or New York State authorities or a material disruption in commercial banking services or securities settlement or clearance services in the United States; or (iii) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, if the effect of any such event specified in this subsection 13(a) in your reasonable judgment makes it impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares. In such event there shall be no liability on the part of any party to any other party except as otherwise provided in Section 10 hereof and except for the expenses to be borne by the Company as provided in Section 8(a) hereof. Any such termination shall have no effect on the obligations of any other Agent, Forward Seller or Forward Purchaser under this Agreement.

(b) Termination by the Company. The Company shall have the right, by giving two (2) days’ notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time after the date of this Agreement.

(c) Termination by the Agents, Forward Sellers or Forward Purchasers. Each Agent, Forward Seller and Forward Purchaser shall have the right, by giving two (2) days’ notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time after the date of this Agreement, solely with respect to such Agent, Forward Seller or Forward Purchaser.

(d) Automatic Termination. Unless earlier terminated pursuant to this Section 13, this Agreement shall automatically terminate on the earlier of (i) the date that the aggregate offering price of the Shares sold pursuant to this Agreement, including any separate underwriting or similar agreement covering principal transactions, equals the Maximum Amount, or (ii) September 23, 2019; provided, however, that this Agreement will continue in effect for the duration of, and solely with respect to, any Confirmation entered into, but not yet settled, before September 23, 2019.

(e) Continued Force and Effect. This Agreement shall remain in full force and effect unless terminated pursuant to Sections 13(a), (b), (c) or (d) above or otherwise by mutual agreement of the parties.

(f) Effectiveness of Termination. Any termination of this Agreement shall be effective on the date specified in such notice of termination, subject to Section 13(d); provided,

however, that such termination shall not be effective until the close of business on the date of receipt of such notice by the Agents, the Forward Sellers or Forward Purchasers or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Shares, such Shares shall settle in accordance with the provisions of this Agreement.

(g) Liabilities. If this Agreement is terminated pursuant to this Section 13, such termination shall be without liability of any party to any other party except as provided in Section 8, and except that, in the case of any termination of this Agreement, Section 5, Section 10, Section 11, Section 12, and Section 15 hereof shall survive such termination and remain in full force and effect.

SECTION 14. Notices. Except as otherwise provided in this Agreement, all notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

SECTION 15. Absence of Fiduciary Relationship. The Company acknowledges and agrees that (a) the Sales Price of the Shares to be sold pursuant to this Agreement will not be established by the Agents, the Forward Sellers or the Forward Purchasers, (b) the determination of the discounts and commissions to be paid pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and Agents, the Forward Sellers and the Forward Purchasers, on the other hand, (c) in connection with any sale contemplated hereby and the process leading to any such transaction, each of the Agents, the Forward Sellers and the Forward Purchasers are acting solely as sales agent and/or principal in connection with

the purchase and sale of the Shares and none of the Agents, the Forward Sellers or the Forward Purchasers are the fiduciary of the Company, or its stockholders, creditors, employees or any other party, (d) the Agents, the Forward Sellers and the Forward Purchasers have not assumed and will not assume an advisory or fiduciary responsibility in favor of the Company with respect to any sale contemplated hereby or the process leading thereto (irrespective of whether the Agents, the Forward Sellers or the Forward Purchasers have advised or are currently advising the Company on other matters) and the Agents, the Forward Sellers and the Forward Purchasers do not have any obligation to the Company with respect to any sale contemplated hereby except the obligations expressly set forth in this Agreement, (e) the Agents, the Forward Sellers, the Forward Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (f) the Agents, the Forward Sellers and the Forward Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to any sale contemplated hereby and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Agents, the Forward Sellers or the Forward Purchasers have advised or are currently advising the Company on related or other matters). The Company agrees that it will not claim that the Agents, the Forward Sellers or the 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 such transaction or the process leading thereto.

SECTION 16. Research Analyst Independence. The Company acknowledges that each Agent’s, Forward Seller’s and Forward Purchaser’s research analysts and research departments are required to be independent from its investment banking division and are subject to certain regulations and internal policies, and that each Agent’s, Forward Seller’s and Forward Purchaser’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions.

The Agents, the Forward Sellers and the Forward Purchasers shall also receive a statement from Hunton & Xxxxxxxx LLP, counsel to the Company, on each Representation Date, to the effect that:

No facts have come to our attention that have caused us to believe that (i) the documents filed by the Company under the Exchange Act that are incorporated by reference in the Prospectus, when filed, were not, on their face, appropriately responsive in all material respects to the requirements of the Exchange Act (except that we express no view with respect to the financial statements, schedules and other financial and accounting information included or incorporated by reference therein or excluded therefrom or compliance with XBRL interactive data requirements), (ii) the Registration Statement, when filed, and the Prospectus, as of its date, appeared on their face to be appropriately responsive in all material respects to the requirements of the Securities Act (except that, in each case, we express no view with respect to the financial statements, schedules and other financial and accounting information included or incorporated by reference therein or excluded therefrom or compliance with XBRL interactive data requirements) and (iii) no facts have come to our attention that have caused us to believe that the Registration Statement, as of its most recent effective date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as of its date and as of each Applicable Time, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that, in each case, we do not express any view as to the financial statements, schedules and other financial and accounting information included or incorporated by reference therein or excluded therefrom, including XBRL interactive data, or the statements contained in the exhibits to the Registration Statement).

In addition, such statement shall confirm that:

The Prospectus has been filed with the Commission within the time period required by Rule 424 under the Securities Act and any required filing of an Issuer Free Writing Prospectus pursuant to Rule 433 under the Securities Act has been filed with the Commission within the time period required by Rule 433(d) under the Securities Act. Assuming the accuracy of the representations and warranties of the Company set forth in Section 5 of the Agreement, the Registration Statement became effective upon filing with the Commission pursuant to Rule 462 under the Securities Act, and that based solely on our review of the Commission’s website, no stop order suspending the effectiveness of the Registration Statement has been issued and, to our knowledge, no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

D-4

Hunton & Xxxxxxxx LLP may state that they have relied as to certain factual matters on information obtained from public officials, officers and representatives of the Company and that the signatures on all documents examined by them are genuine, assumptions of which such counsel has not independently verified.
