Item 1.01. Entry into a Material Definitive Agreement.

On August 7, 2025, American Water Works Company, Inc. (“American Water”) entered into an additional forward sale agreement (each an “Additional Forward Sale Agreement,” and, collectively, the “Additional Forward Sale Agreements”) with each of Wells Fargo Bank, National Association, JPMorgan Chase Bank, National Association, and Mizuho Markets Americas LLC (with Mizuho Securities USA LLC acting as agent) (each, a “Forward Purchaser”), relating to an aggregate of 1,056,338 shares (the “Borrowed Optional Shares”) of American Water’s common stock, par value $0.01 per share (“Common Stock”).

On August 7, 2025, the Forward Sellers (as defined below) borrowed from third parties the Borrowed Optional Shares and the Forward Sellers sold the Borrowed Optional Shares in connection with the Additional Forward Sale Agreements to the underwriters named in the Equity Underwriting Agreement referred to under Item 8.01 below, for whom Wells Fargo Securities, LLC, J.P. Morgan Securities LLC and Mizuho Securities USA LLC, are acting as representatives.

The Additional Forward Sale Agreements provide for settlement on a settlement date or dates to be specified at American Water’s discretion on or prior to December 31, 2026. On a settlement date or dates, if American Water elects to physically settle one or more Additional Forward Sale Agreements, American Water will issue shares of Common Stock to the relevant Forward Purchaser at the then-applicable forward sale price. The forward sale price under the Additional Forward Sale Agreements is initially $139.657 per share, which is equal to the price to public per share less an underwriting discount reflected in the Equity Underwriting Agreement. Each Additional Forward Sale Agreement provides that the initial forward sale price will be subject to adjustment based on a floating interest rate factor equal to the overnight bank funding rate less a spread, and will be subject to decrease on each of certain dates specified in such Additional Forward Sale Agreement by amounts related to expected dividends on shares of Common Stock during the term of such Additional Forward Sale Agreement. If the overnight bank funding rate is less than the spread on any day, the interest rate factor will result in a reduction of the forward sale price for such day.

Each Additional Forward Sale Agreement will be physically settled unless American Water elects to settle such Additional Forward Sale Agreement in cash or to net share settle such Additional Forward Sale Agreement (which American Water has the right to do, subject to certain conditions, other than in the limited circumstances set forth in the Additional Forward Sale Agreements). American Water estimates that it will receive net proceeds of approximately $147.5 million, before deducting estimated offering expenses, subject to the price adjustment and other provisions of the Additional Forward Sale Agreements, in the event of full physical settlement of all of the Additional Forward Sale Agreements. If American Water elects cash settlement or net share settlement for all or a portion of the shares of Common Stock underlying the relevant Additional Forward Sale Agreement, American Water would expect such Forward Purchaser or one of its affiliates to purchase a number of shares of Common Stock corresponding to the portion for which American Water elects cash settlement or net share settlement in order to satisfy its or its affiliate’s obligation to return the shares of Common Stock such Forward Purchaser had borrowed in connection with sales of Common Stock and, if applicable in connection with net share settlement, to deliver shares of Common Stock to American Water. If the market value of Common Stock at the time of such purchase is above the applicable forward sale price at that time, American Water will pay or deliver, as the case may be, to the relevant Forward Purchaser under such Additional Forward Sale Agreement, an amount in cash, or a number of shares of Common Stock with a market value, equal to such difference multiplied by the number of shares of Common Stock underlying the relevant Additional Forward Sale Agreement subject to cash settlement or net share settlement, as the case may be. Conversely, if the market value of Common Stock at the time of such purchase is below the applicable forward sale price at that time, such Forward Purchaser will pay or deliver, as the case may be, to American Water under the relevant Additional Forward Sale Agreement, an amount in cash, or a number of shares of Common Stock with a market value, equal to such difference multiplied by the number of shares of Common Stock underlying the relevant Additional Forward Sale Agreement subject to cash settlement or net share settlement, as the case may be. American Water intends to use any net cash proceeds that it may receive upon a settlement of an Additional Forward Sale Agreement for general corporate purposes.

Each Forward Purchaser will have the right to accelerate each Additional Forward Sale Agreement to which it is a party (or, in certain cases, the portion thereof that such Forward Purchaser determines is affected by the relevant event) and require American Water to physically settle such Additional Forward Sale Agreement on a date specified

2

by such Forward Purchaser if (i) in the good faith, commercially reasonable judgment of such Forward Purchaser, it or its affiliate is unable to borrow a number of shares of Common Stock equal to the number of shares to be delivered by American Water upon physical settlement of such Additional Forward Sale Agreement or such Forward Purchaser or its affiliate is unable to borrow such number of shares at a rate equal to or less than an agreed maximum stock loan rate; (ii) American Water declares any dividend or distribution on shares of Common Stock payable in (a) cash in excess of a specified amount (other than an extraordinary dividend), (b) securities of another company, or (c) any other type of securities (other than Common Stock), rights, warrants or other assets for payment (cash or other consideration) at less than the prevailing market price, as reasonably determined by such Forward Purchaser; (iii) certain ownership thresholds applicable to such Forward Purchaser are exceeded; (iv) an event is announced that, if consummated, would result in an extraordinary event (as defined in such Additional Forward Sale Agreement) including, among other things, certain mergers and tender offers, as well as certain events such as a delisting of the Common Stock (each as more fully described in the Additional Forward Sale Agreements); or (v) certain other events of default or termination events occur, including, among other things, any material misrepresentation made by American Water in connection with American Water’s entry into such Additional Forward Sale Agreement, American Water’s bankruptcy (except in certain circumstances described in the Additional Forward Sale Agreements) or certain changes in law (each as more fully described in the Additional Forward Sale Agreements).

The foregoing description of the Additional Forward Sale Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of each such Additional Forward Sale Agreement, which has been filed as Exhibit 10.1, Exhibit 10.2, and Exhibit 10.3 hereto, respectively, and each of which is incorporated by reference herein in response to this Item 1.01.

Item 8.01. Other Events.

Equity Option Closing

As previously disclosed in American Water’s Current Report on Form 8-K filed on August 6, 2025, on August 4, 2025, American Water entered into an underwriting agreement (the “Equity Underwriting Agreement”) with Wells Fargo Securities, LLC, J.P. Morgan Securities LLC and Mizuho Securities USA LLC, as the representatives of the underwriters named therein (the “Equity Underwriters”), Wells Fargo Securities, LLC, J.P. Morgan Securities LLC and Mizuho Securities USA LLC, as the forward sellers (each, a “Forward Seller”), and each of the Forward Purchasers, related to the public offering and sale of an aggregate of 7,042,254 shares of Common Stock.

Under the terms of the Equity Underwriting Agreement, American Water granted the Equity Underwriters a 30-day option (the “Equity Option”) to purchase the Borrowed Optional Shares. On August 7, 2025, the Equity Underwriters exercised the Equity Option in full with respect to the Borrowed Optional Shares, and in connection therewith, on August 7, 2025, American Water entered into the Additional Forward Sale Agreements, each as described in Item 1.01 above, relating to the Borrowed Optional Shares. On August 8, 2025, American Water closed the offering and sale of the Borrowed Optional Shares.

The Borrowed Optional Shares were registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a Registration Statement on Form S-3 (File No. 333-277166).

This Current Report on Form 8-K is being filed, in part, to report the closing of the offering of the Borrowed Optional Shares and the sale of the Borrowed Optional Shares, and to include, as exhibits, certain documents executed in connection with such registered public offering and sale.

Closing of Offering of American Water Capital Corp. Senior Notes

On August 6, 2025, American Water Capital Corp. (“AWCC”), a wholly owned finance subsidiary of American Water, agreed to sell $900 million aggregate principal amount of its 5.700% Senior Notes due 2055 (the “Notes”) pursuant to an underwriting agreement, dated August 6, 2025, by and among AWCC and American Water, and U.S. Bancorp Investments, Inc., J.P. Morgan Securities LLC and PNC Capital Markets LLC, as representatives of the several underwriters named therein. The Notes have the benefit of a support agreement, dated June 22, 2000 and amended as of July 26, 2000, from American Water (the “Support Agreement”).

3

The Notes and the obligations of American Water represented by the Support Agreement were registered under the Securities Act, pursuant to a Registration Statement on Form S-3 (File Nos. 333-277166-01 and 333-277166). At the closing of this offering, on August 8, 2025, AWCC received, after deduction of underwriting discounts and before deduction of offering expenses, net proceeds of approximately $887.2 million. AWCC intends to use the net proceeds of the offering (1) to lend funds to American Water and its subsidiaries in its Regulated Businesses segment (which is comprised of utilities that provide water and wastewater services and are generally subject to regulation by state utility commissions or other entities engaged in utility regulation); (2) to repay commercial paper obligations of AWCC; and (3) for general corporate purposes.

The Notes were issued pursuant to the Indenture, dated as of December 4, 2009, by and between AWCC and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee, as supplemented by an officers’ certificate establishing the terms of the Notes.

This Current Report on Form 8-K is being filed, in part, to report the closing of the offering of the Notes and to include, as exhibits, certain documents executed in connection with such registered public offering and sale.

8. (a) (i) Each of the Parent and the Company represents and agrees that, other than the final term sheet in a form substantially consistent with Schedule III hereto and filed pursuant to Section 7(a) hereof, without the prior written consent of the Representatives, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; (ii) each Underwriter represents and agrees that, without the prior written consent of the Company, other than one or more term sheets relating to the Securities substantially consistent with Schedule III hereto, containing no “issuer information” (as defined in Rule 433(h)(2) under the Act) that was not included in the Preliminary Prospectus or Pricing Prospectus, it has not made and will not make any offer relating to the Securities that would constitute a free writing prospectus; and (iii) any such free writing prospectus the use of which has been consented to by the Company and the Representatives is listed on Schedule II hereto;

(b) The Company has complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and the Company represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Act to avoid a requirement to file with the Commission any electronic road show; and

(c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or, when taken together with the Pricing Prospectus, would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Representatives and, if requested by the Representatives, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with the Underwriter Information.

17

9. Each of the Parent and the Company covenants and agrees with the several Underwriters that the Parent and the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Parent’s and the Company’s counsel and accountants in connection with the registration of the Securities under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any agreement among Underwriters, this Agreement, the Indenture, the Support Agreement, any Blue Sky survey, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 7(c) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with any Blue Sky survey; (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities; (vi) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture, the Securities and the Support Agreement; and (vii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section; provided, however, that reimbursements to the Underwriters, if any, shall be limited to expenses actually incurred; and provided further that in the case of clause (iii), the Parent and the Company shall not be requested to cover expenses of counsel for the Underwriters in excess of $5,000 in the aggregate.

10. The obligations of the Underwriters hereunder shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Parent and the Company herein are, at and as of the Time of Delivery, true and correct, the condition that the Parent and the Company shall have performed all of their obligations hereunder theretofore to be performed, and the following additional conditions:

(a) The Prospectus shall have been filed with the Commission pursuant to Rule 424(b) under the Act within the applicable time period prescribed for such filing by the rules and regulations under the Act and in accordance with Section 7(a) hereof; the final term sheet contemplated by Section 7(a) hereof, and any other material required to be filed by the Company pursuant to Rule 433(d) under the Act, shall have been filed with the Commission within the applicable time period prescribed for such filings by Rule 433; no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for

18

that purpose shall have been initiated or threatened by the Commission and no notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act shall have been received; no stop order suspending or preventing the use of the Prospectus or any Issuer Free Writing Prospectus shall have been initiated or threatened by the Commission; and all requests for additional information on the part of the Commission shall have been complied with to the reasonable satisfaction of the Representatives;

(b) Sullivan & Cromwell LLP, counsel for the Underwriters, shall have furnished to the Representatives such written opinions, dated the Time of Delivery, in form and substance satisfactory to the Representatives, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters;

(c) Morgan, Lewis & Bockius LLP, counsel for the Company, shall have furnished to the Representatives their written opinion and 10b-5 statement, each dated the Time of Delivery, in the form attached as Annexes II-A and II-B hereto;

(d) Jeffrey M. Taylor, Secretary of the Company and Vice President, Chief SEC Counsel and Secretary of the Parent, shall have furnished to the Representatives his written opinion, dated the Time of Delivery, in the form attached as Annex III hereto;

(f) (i) Since the date of the latest audited financial statements included or incorporated by reference in the Pricing Prospectus, none of the Parent, the Company or any of the Parent’s other subsidiaries has sustained any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree and (ii) since the date as of which information is given in the Pricing Prospectus there has not been (A) any material decrease in the number of shares of outstanding capital stock of the Parent or increase in consolidated long-term debt of the Parent and its consolidated subsidiaries, or (B) any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, stockholders’ equity or results of operations of the Parent, the Company and the Parent’s other subsidiaries, otherwise, in any such case described in clause (i) or (ii), than as set forth or contemplated in the Pricing Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus;

19

(g) On or after the Applicable Time, (i) no downgrading shall have occurred in the rating accorded the Parent’s or the Company’s debt securities by S&P Global Ratings, a division of S&P Global Inc., or Moody’s Investors Service, Inc., each a “nationally recognized statistical rating organization”, as that term is defined by Section 3(a)(62) of the Exchange Act, and (ii) neither such organization shall have publicly announced (other than any announcement made prior to the Applicable Time) that it has under surveillance or review, with possible negative implications, its rating of any of the Parent’s or the Company’s debt securities;

(i) Each of the Parent and the Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery certificates of officers of the Parent and the Company reasonably satisfactory to the Representatives as to the accuracy of the representations and warranties of the Parent and the Company, respectively, herein at and as of the Time of Delivery, as to the performance by the Parent and the Company of all their respective obligations hereunder to be performed at or prior to the Time of Delivery, as to the matters set forth in subsections (a), (f) and (g) of this Section 10 and as to such other matters as the Representatives may reasonably request.

20

11. (a) The Parent and the Company will, jointly and severally, indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Parent and the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information.

(b) Each Underwriter will, severally and not jointly, indemnify and hold harmless the Parent and the Company against any losses, claims, damages or liabilities, joint or several, to which the Parent or the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, 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 any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information; and will reimburse the Parent and the Company for any legal or other expenses reasonably incurred by the Parent or the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

21

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party 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. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ one separate counsel, and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate firm (in addition to one local counsel in each jurisdiction) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) in an action where both the indemnifying and the indemnified party are actual or potential defendants, the indemnified party shall have reasonably concluded that there are actual or potential conflicting interests between the indemnifying party and the indemnified party, including situations in which there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. No indemnified party shall, without the written consent of the indemnifying party (such consent not to 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.

22

(d) If the indemnification provided for in this Section 11 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 Parent and the Company, on the one hand, and the Underwriters, on the other, from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Parent and the Company, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Parent and the Company, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Parent and the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover page of the Prospectus. 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 Parent or the Company on the one hand or the Underwriter Information on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Parent, the Company, and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

23

(e) The obligations of the Parent and the Company under this Section 11 shall be in addition to any liability which the Parent and the Company may otherwise have and shall extend, upon the same terms and conditions, to the directors, officers, employees and agents of each Underwriter and to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 11 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and employee of the Parent or the Company and to each person, if any, who controls the Parent or the Company within the meaning of the Act.

12. (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, the Representatives may in their discretion arrange for any of the Representatives or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 12 with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

24

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 9 hereof and the indemnity and contribution agreements in Section 11 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

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

14. If for any reason, other than a default by the Underwriters in their obligation to purchase the Securities, any Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all reasonable expenses approved in writing by the Representatives, including reasonable fees and disbursements of counsel, incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities not so delivered, but the Parent and the Company shall then be under no further liability to the Underwriters except as provided in Sections 9 and 11 hereof.

15. In all dealings hereunder, the Representatives shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives jointly.

25

16. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the Representatives in care of: U.S. Bancorp Investments, Inc., 214 North Tryon Street, 26th Floor Charlotte, NC 28202-1078, Attention: Investment Grade Syndicate or facsimile transmission to (877) 774-3462; J.P. Morgan Securities LLC, 383 Madison Avenue New York, NY 10179, Attention: Investment Grade Syndicate Desk, or by facsimile transmission to (212) 834-6081; or PNC Capital Markets LLC, 300 Fifth Avenue, 10^th Floor, Pittsburgh, PA 15222, Attention: Debt Capital Markets, Fixed Income Transaction Execution, or by email at capitalmarketsnotices@pnc.com; and if to the Parent or the Company shall be delivered or sent by mail to the address of the Parent set forth in the Registration Statement, or email at stacy.mitchell@amwater.com, Attention: Stacy A. Mitchell, Executive Vice President and General Counsel. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

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

18. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Parent and the Company and, to the extent provided in Sections 11 and 13 hereof, the officers and directors of the Parent and the Company and each person who controls the Parent and the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

19. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

20. The Parent and the Company acknowledge and agree that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Parent and the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not as an agent or fiduciary of the Parent or the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Parent or the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Parent or the Company) or any other obligation to the Parent or the Company except the obligations expressly set forth in this Agreement and (iv) the Parent and the Company have consulted their own legal and financial advisors to the extent they deemed appropriate. The Parent and the Company agree that they will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Parent or the Company, in connection with such transaction or the process leading thereto.

26

21. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Parent, the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

22. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

23. THE PARENT, THE COMPANY AND EACH OF THE UNDERWRITERS HEREBY IRREVOCABLY WAIVE, 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.

24. 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 counterparts shall together constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, or other transmission method), and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

25. Notwithstanding anything herein to the contrary, each of the Parent and the Company are authorized to disclose to any persons the tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Parent and the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax treatment” means U.S. Federal and State income tax treatment, and “tax structure” is limited to any facts that may be relevant to that treatment.

26. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

27

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a State of the United States.

(c) For purposes of this Section 26, the following terms shall have the meanings indicated:

(i) “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

(1) Neither of these ratings is a recommendation to buy, sell or hold these securities. Each rating may be subject to revision or withdrawal at any time, and should be evaluated independently of any other rating.

The term “Treasury Rate” has the meaning ascribed to that term in the Issuer’s Preliminary Prospectus Supplement, dated August 6, 2025.

* The underwriters expect to deliver the notes in book-entry form only through the facilities of The Depository Trust Company against payment in New York, New York on or about the second business day following the date of the prospectus supplement, or “T+2”. Trades of securities in the secondary market generally are required to settle in one business day, referred to as T+1, unless the parties to a trade agree otherwise. Accordingly, by virtue of the fact that the initial delivery of the notes will not be made on a T+1 basis, investors who wish to trade the notes prior to the first business day before delivery of the notes will be required to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Investors of the notes who wish to trade the notes on any date prior to the first business day before delivery should consult their own advisors.

The Issuer and the Support Provider have filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates.

American Water Capital Corp., a corporation duly organized and existing under the laws of Delaware (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of ________________Dollars on September 1, 2055, and to pay interest thereon from August 8, 2025 or from the most recent Interest Payment Date to which interest has been paid or as duly provided for semi-annually on March 1 and September 1, in arrears, commencing March 1, 2026, and on any earlier Redemption Date (as defined herein), at the rate of 5.700% per annum, until the principal hereof is paid or made available for payment. Interest on this Security shall be computed assuming a 360-day year consisting of twelve 30-day months.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the close of business on the fifteenth day (whether or not a Business Day) next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

TRUSTEE’S CERTIFICATION OF AUTHENTICATION

This is one of the Securities of the series designated herein and referred to in the within-mentioned Indenture.

COMPUTERSHARE TRUST COMPANY, N.A.,
	As Trustee
By
	Authorized Signatory
Dated:

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of December 4, 2009 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

The Company may from time to time, without the consent of the Holders, create and issue Additional Securities, so that each such further issue shall be consolidated and form a single series with the Outstanding Securities of this series.

All or a portion of the Securities of this series may be redeemed at the option of the Company at any time or from time to time (each, a “Redemption Date”). Prior to March 1, 2055 (the “Par Call Date”), the Company may redeem the Securities of this series at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

• (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities of this series matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis points less (b) interest accrued to the Redemption Date, and

• 100% of the principal amount of the Securities of this series to be redeemed,

plus, in either case, accrued and unpaid interest thereon to that Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities of this series at its option, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities of this series being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date for the Securities of this series, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable:

(1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or

(2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

(3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life.

For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third business day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notices of redemption will be given in accordance with the Indenture at least 30 but not more than 60 days before a Redemption Date, except that redemption notices may be sent more than 60 days prior to a Redemption Date if the notice is issued in connection with a satisfaction and discharge of the Indenture.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

6

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

In connection with any proposed transfer of this Security if this Security ceases to be a Global Security, the Company or DTC shall be required to provide or cause to be provided to the Trustee all information that is (i) available to the Company or the DTC, as applicable, (ii) necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and (iii) specifically and timely requested in writing by

the Trustee. Any transferor shall also provide or cause to be provided to the Trustee all information that is (i) available to such transferor, (ii) necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Code Section 6045, and (iii) specifically and timely requested by the Trustee. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF.

Ladies and Gentlemen:

We have acted as counsel to American Water Works Company, Inc., a Delaware corporation (“AWW”), and American Water Capital Corp., a Delaware corporation (the “Company”), in connection with the issuance by the Company of $900,000,000 aggregate principal amount of its 5.700% Senior Notes due 2055 (the “Notes”), issued under the Indenture, dated as of December 4, 2009 (the “Indenture”), between the Company and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee (the “Trustee”), which Notes have the benefit of the Support Agreement, dated June 22, 2000, as amended as of July 26, 2000, between the Company and AWW (the “Support Agreement”).

We have participated in the preparation of or reviewed (1) the Registration Statement on Form S-3 (Registration Nos. 333-277166-01 and 333-277166) (the “Registration Statement”), which Registration Statement was filed jointly by the Company and AWW with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”); (2) the prospectus dated February 20, 2024 (the “Base Prospectus”), forming a part of the Registration Statement, as supplemented by a prospectus supplement dated August 6, 2025 (the “Prospectus Supplement”) relating to the Notes, both such prospectus and prospectus supplement filed pursuant to Rule 424(b) under the Securities Act; (3) the Indenture; (4) the Support Agreement; (5) the certificate of incorporation of the Company; (6) the by-laws, as amended, of the Company; (7) the restated certificate of incorporation of AWW; (8) the amended and restated bylaws of AWW; and (9) such other corporate records, certificates and other documents (including a receipt executed on behalf of the Company acknowledging receipt of payment for the Notes) and such questions of law as we have considered necessary or appropriate for the purposes of this opinion.

Based on the foregoing, we are of the opinion that the Notes and the Support Agreement, as it relates to the Notes, are valid and binding obligations of the Company and AWW, respectively, except as may be limited or affected by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws affecting creditors’ rights and remedies generally and general principles of equity.

Ladies and Gentlemen,

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the transaction entered into between us on the Trade Date specified below (the “Transaction”). This Confirmation constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.

1. The definitions and provisions contained in the 2000 ISDA Definitions (the “2000 Definitions”) and the 2002 ISDA Equity Derivatives Definitions (the “2002 Definitions” and, together with the 2000 Definitions, the “Definitions”), each as published by the International Swaps and Derivatives Association, Inc., are incorporated into this Confirmation.

Each party further agrees that this Confirmation together with the Agreement evidence a complete binding agreement between Party A and Party B as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Party A and Party B had executed an agreement in such form on the Trade Date (but without any Schedule except for (i) the election of the laws of the State of New York as the governing law (without regard to New York’s choice of laws doctrine other than Title 14 of Article 5 of the New York General Obligations Law); (ii) the election of U.S. Dollars as the Termination Currency; (iii) the word “first” shall be replaced with the word “third” each time it occurs in Section 5(a)(i) of the Agreement; and (iv) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Party A as if (a) the phrase “, or becoming capable at such time of being declared,” were deleted from Section 5(a)(vi)(1) of the Agreement, (b) the “Threshold Amount” with respect to Party A were three percent of the shareholders’ equity of Party A, (c) the following language were added to the end of Section 5(a)(vi) of the Agreement: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (x) the default was caused solely by error or omission of an administrative or operational nature; (y) funds were available to enable the party to make the payment when due; and (z) the payment is made within one Local Business Day of such party’s receipt of written notice of its failure to pay.”; and (d) the term “Specified Indebtedness” had the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect of deposits received in the ordinary course of a party’s banking business. The parties hereby agree that no Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement. For purposes of the 2002 Definitions, the Transaction is a Share Forward Transaction.

In the event of any inconsistency among the Agreement, this Confirmation, the 2002 Definitions, and the 2000 Definitions, the following will prevail in the order of precedence indicated: (i) this Confirmation, (ii) the 2002 Definitions, (iii) the 2000 Definitions, and (iv) the Agreement.

	Settlement Date:	Any Scheduled Trading Day following the Effective Date and up to and including the Maturity Date, as designated by (a) Party A pursuant to “Termination Settlement” below or (b) Party B in a written notice (a “Settlement Notice”) that satisfies the Settlement Notice Requirements and is delivered to Party A no later than (i) 12:30 p.m. (New York City time) on the Scheduled Trading Day immediately prior to such Settlement Date, which may be the Maturity Date, if Physical Settlement applies, and (ii) a number of Scheduled Trading Days equal to the Notice Length prior to such Settlement Date, which may be the Maturity Date, if Cash Settlement or Net Share Settlement applies; provided that (i) the Maturity Date shall be a Settlement Date if on such date the Base Amount is greater than zero, (ii) if Physical Settlement applies and a Settlement Date specified above (including a Settlement Date occurring on the Maturity Date) is not a Clearance System Business Day, the Settlement Date shall be the next following Clearance System Business Day and (iii) if Cash Settlement or Net Share Settlement applies and Party A shall have fully unwound its hedge during the related Unwind Period with respect to the relevant Settlement Shares by a date that is more than one Scheduled Trading Day prior to a Settlement Date specified above, Party A may, by written notice to Party B, specify any Scheduled Trading Day prior to such originally specified Settlement Date as the Settlement Date.
	Notice Length:	(a) 30 Scheduled Trading Days, if (x) Party B shall not have designated, on or prior to the date of such Settlement Notice, a Settlement Date under any Other Forward (as defined under “Other Forwards” below) for which Cash Settlement or Net Share Settlement is applicable or (y) Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under one or more Other Forwards for which Cash Settlement or Net Share Settlement is applicable but no Overlap Unwind Period (as defined under “Other Forwards” below) would occur with respect to any Other Forward as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder; or

3

		(b) 60 Scheduled Trading Days, if Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under one or more Other Forwards with one or both of the Other Forward Counterparties for which Cash Settlement or Net Share Settlement is applicable and an Overlap Unwind Period would occur with respect to one or more Other Forwards with one (but only one) Other Forward Counterparty as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder; or
		(c) 90 Scheduled Trading Days, if Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under two or more Other Forwards with both of the Other Forward Counterparties for which Cash Settlement or Net Share Settlement is applicable and an Overlap Unwind Period would occur with respect to two or more Other Forwards with both Other Forward Counterparties as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder.
	Settlement Shares:	With respect to any Settlement Date, a number of Shares, not to exceed the Base Amount, designated as such by Party B in the related Settlement Notice or by Party A pursuant to “Termination Settlement” below; provided that on the Maturity Date the number of Settlement Shares shall be equal to the Base Amount on such date.
	Settlement Method:	Physical Settlement, Cash Settlement or Net Share Settlement, at the election of Party B as set forth in a Settlement Notice delivered on or after the Effective Date that satisfies the Settlement Notice Requirements; provided that Physical Settlement shall apply (i) if no Settlement Method is validly selected, (ii) with respect to any Settlement Shares in respect of which Party A is unable, in its good faith and commercially reasonable judgment, to unwind its hedge by the end of the Unwind Period in a manner that, in the good faith and commercially reasonable judgment of Party A based upon the advice of counsel, is consistent with the requirements for qualifying for the safe harbor provided by Rule 10b-18 under the Exchange Act or due to the lack of sufficient liquidity in the Shares on any Exchange Business Day during the Unwind Period, or (iii) to any Termination Settlement Date (as defined below under “Termination Settlement”). For the avoidance of doubt, during any Unwind Period, Party B may elect Physical Settlement (as described above) in respect of any Shares that are not Settlement Shares for the Cash Settlement or Net Share Settlement, as the case may be, to which such Unwind Period relates.
		For greater clarity, with respect to any Settlement Date in respect of which Cash Settlement applies, Party A shall be deemed to have completed unwinding its hedge in respect of the portion of the Transaction to be settled on such Settlement Date when it purchases (or, to the extent applicable, unwinds derivative positions (including, but not limited to, swaps or options related to the Shares) resulting in Party A’s synthetic purchase of) an aggregate number of Shares equal to the number of Settlement Shares for such Settlement Date.
	Settlement Notice Requirements:	Notwithstanding any other provision hereof, a Settlement Notice delivered by Party B that specifies Cash Settlement or Net Share Settlement will not be effective to establish a Settlement Date or require Cash Settlement or Net Share Settlement unless Party B delivers to Party A with such Settlement Notice a representation signed by Party B substantially in the following form: “As of the date of this Settlement Notice, Party B is not aware of any material nonpublic information concerning itself or the Shares, and is designating the date contained herein as a Settlement Date and is electing Cash Settlement or Net Share Settlement, as the case may be, in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws.”

4

	Unwind Period:	Subject to the provisions below under the caption “Other Forwards,” each Exchange Business Day that is not a Suspension Day during the period from and including the first Exchange Business Day following the date Party B validly elects Cash Settlement or Net Share Settlement in respect of a Settlement Date through the Scheduled Trading Day immediately preceding such Settlement Date (or the immediately preceding Exchange Business Day if such Scheduled Trading Day is not an Exchange Business Day); subject to “Termination Settlement” below. If any Exchange Business Day during an Unwind Period is a Disrupted Day, the Calculation Agent shall make commercially reasonable adjustments to the terms of the Transaction (including, without limitation, the Cash Settlement Amount, the number of Net Share Settlement Shares and the 10b-18 VWAP) to account for the occurrence of such Disrupted Day.
	Suspension Day:	Any Exchange Business Day on which Party A reasonably determines based on the advice of counsel that Cash Settlement or Net Share Settlement may violate applicable securities laws. Party A shall notify Party B if it receives such advice from its counsel.
	Market Disruption Event:	Section 6.3(a) of the 2002 Definitions is hereby amended by replacing clause (ii) in its entirety with “(ii) an Exchange Disruption, or” and inserting immediately following clause (iii) the phrase “; in each case that the Calculation Agent determines is material.”
	Exchange Act:	The Securities Exchange Act of 1934, as amended from time to time.
	Physical Settlement:	On any Settlement Date in respect of which Physical Settlement applies, Party B shall deliver to Party A through the Clearance System the Settlement Shares for such Settlement Date, and Party A shall pay to Party B, by wire transfer of immediately available funds to an account designated by Party B, an amount in cash equal to the Physical Settlement Amount for such Settlement Date, on a delivery versus payment basis. If, on any Settlement Date, the Shares to be delivered by Party B to Party A hereunder are not so delivered (the “Deferred Shares”), and a Forward Price Reduction Date occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to Party A, then the portion of the Physical Settlement Amount payable by Party A to Party B in respect of the Deferred Shares shall be reduced by an amount equal to the Forward Price Reduction Amount for such Forward Price Reduction Date, multiplied by the number of Deferred Shares.
	Physical Settlement Amount:	For any Settlement Date in respect of which Physical Settlement applies, an amount in cash equal to the product of (i) the Forward Price on such Settlement Date and (ii) the number of Settlement Shares for such Settlement Date.
	Cash Settlement:	On any Settlement Date in respect of which Cash Settlement applies, if the Cash Settlement Amount for such Settlement Date is a positive number, Party A will pay such Cash Settlement Amount to Party B. If the Cash Settlement Amount is a negative number, Party B will pay the absolute value of such Cash Settlement Amount to Party A. Such amount shall be paid on the Settlement Date by wire transfer of immediately available funds.
	Cash Settlement Amount:	For any Settlement Date in respect of which Cash Settlement or Net Share Settlement applies, an amount determined by the Calculation Agent equal to the difference between (1) the product of (i) (A) the average Forward Price over the period beginning on, and including, the date that is one Settlement Cycle following the first day of the applicable Unwind Period and ending on, and including, such Settlement Date (calculated assuming no reduction to the Forward Price for any Forward Price Reduction Date that occurs during the applicable Unwind Period, except as set forth in clause (2) below), minus USD 0.01, minus (B) the average of the 10b-18 VWAP prices per Share on each Exchange Business Day during such Unwind Period (provided that during any Overlap Unwind Period , only those Exchange Business Days that constitute Overlap Observation Days shall be included

5

		in such calculation) (clause (B), the “Average Unwind 10b-18 VWAP”), multiplied by (ii) the number of Settlement Shares for such Settlement Date, minus (2) the product of (i) the Forward Price Reduction Amount for any Forward Price Reduction Date that occurs during such Unwind Period, multiplied by (ii) the number of Settlement Shares with respect to which Party A has not unwound its hedge as of such Forward Price Reduction Date.
	Net Share Settlement:	On any Settlement Date in respect of which Net Share Settlement applies, if the Cash Settlement Amount is a (i) positive number, Party A shall deliver to Party B the Net Share Settlement Shares, or (ii) negative number, Party B shall deliver to Party A the Net Share Settlement Shares; provided that if Party A determines in its good faith judgment that it would be required to deliver Net Share Settlement Shares to Party B, Party A may elect to deliver a portion of such Net Share Settlement Shares on one or more dates prior to the applicable Settlement Date.
	Net Share Settlement Shares:	For any Settlement Date in respect of which Net Share Settlement applies, a number of Shares equal to the absolute value of the Cash Settlement Amount divided by the Average Unwind 10b-18 VWAP, with the number of Shares rounded up in the event such calculation results in a fractional number of Shares. If, on any Settlement Date, the Shares to be delivered by Party B or Party A hereunder upon Net Share Settlement are not so delivered (the “Net Share Deferred Shares”), and a Forward Price Reduction Date occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to such party, then the portion of the Net Share Settlement Shares deliverable by Party A or Party B in respect of the Net Share Deferred Shares shall be adjusted by the Calculation Agent to reflect the occurrence of such Forward Price Reduction Amount for such Forward Price Reduction Date.
	10b-18 VWAP:	For any Exchange Business Day during the Unwind Period that is not a Suspension Day, the volume-weighted average price at which the Shares trade as reported in the composite transactions for the Exchange on such Exchange Business Day, excluding (i) trades that do not settle regular way, (ii) opening (regular way) reported trades on the Exchange on such Exchange Business Day, (iii) trades that occur in the last ten minutes before the scheduled close of trading on the Exchange on such Exchange Business Day and ten minutes before the scheduled close of the primary trading session in the market where the trade is effected, and (iv) trades on such Exchange Business Day that do not satisfy the requirements of Rule 10b-18(b)(3), as determined in good faith by the Calculation Agent. Party B acknowledges that Party A may refer to the Bloomberg Page “AWK <Equity> AQR SEC” (or any successor thereto), in its discretion, for such Exchange Business Day to determine the 10b-18 VWAP.
	Settlement Currency:	USD.
	Failure to Deliver:	Inapplicable.

Adjustments:

   Extraordinary Events: The consequences that would otherwise apply under Article 12 of the 2002 Definitions to any applicable Extraordinary Event shall not apply.

		(i) Shares withheld from employees of Party B or its Affiliates to pay certain withholding taxes upon the vesting of Share awards or options granted to such employees under compensation or benefit plans of Party B; and
		(ii) Shares purchased in connection with the reinvestment of dividends by recipients of Share awards under Party B’s compensation or benefit plans; and

The Calculation Agent shall notify Party B prior to making any such adjustment to the Forward Price and, upon the request of Party B, Party A shall provide an itemized list of the Stock Loan Fees for the applicable period specified above in this paragraph.

(c) Party B agrees to provide Party A with at least three days’ written notice (an “Issuer Repurchase Notice”) prior to executing any repurchase of Shares by Party B or any of its subsidiaries (or entering into any contract that would require, or give the option to, Party B or any of its subsidiaries, to purchase or repurchase Shares), whether out of profits or capital or whether the consideration for such repurchase is cash, securities or otherwise (an “Issuer Repurchase”), that alone or in the aggregate would result in the Base Amount Percentage (as defined below) being either (i) equal to or greater than 9.0% of the outstanding Shares or (ii) greater by 0.5% or more than the Base Amount Percentage at the time of the immediately preceding Issuer Repurchase Notice (or in the case of the first such Issuer Repurchase Notice, greater than the Base Amount Percentage as of the later of the date hereof or the immediately preceding Settlement Date, if any).

9

(h) Party B will not engage in any “distribution” (as defined in Regulation M under the Exchange Act (“Regulation M”)) that would cause a “restricted period” (as defined in Regulation M) to occur during any Unwind Period.

(i) Party B is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended).

(j) In addition to any other requirements set forth herein, Party B agrees not to elect Cash Settlement or Net Share Settlement if, in the reasonable judgment of either Party A or Party B, such settlement or Party A’s related market activity would result in a violation of the U.S. federal securities laws or any other federal or state law or regulation applicable to Party B.

(ii) Party A and its Affiliates may also be active in the market for the Shares and Share-linked transactions other than in connection with hedging activities in relation to the Transaction;

(iii) Party A shall make its own determination as to whether, when or in what manner any hedging or market activities in Party B’s securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Forward Price and the 10b-18 VWAP;

(iv) any market activities of Party A and its Affiliates with respect to the Shares may affect the market price and volatility of the Shares, as well as the Forward Price and 10b-18 VWAP, each in a manner that may be adverse to Party B; and

(v) the Transaction is a derivatives transaction in which it has granted Party A the right, under certain circumstances, to receive cash or Shares, as the case may be; Party A may purchase Shares for its own account at an average price that may be greater than, or less than, the effective price paid by Party B under the terms of the Transaction.

Party B, status as an Affiliate of Party B or otherwise), irrespective of whether such stock loan is effected by Party A or an Affiliate of Party A. Accordingly, subject to the provisions of “Private Placement Procedures” below, Party B agrees that the Shares that it delivers to Party A on each Settlement Date will not bear a restrictive legend and that such Shares will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System.

Covenants of Party A:

(a) Unless the provisions set forth below under “Private Placement Procedures” shall be applicable, Party A shall use any Shares delivered by Party B to Party A on any Settlement Date to return Shares to securities lenders to close out open Share loans created by Party A or an Affiliate of Party A in the course of Party A’s or such Affiliate’s hedging activities related to Party A’s exposure under this Confirmation.

(b) In connection with bids and purchases of Shares in connection with any Cash Settlement or Net Share Settlement of the Transaction, Party A shall use its commercially reasonable efforts to conduct its activities, or cause its Affiliates to conduct their activities, in a manner consistent with the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act, as if such provisions were applicable to such purchases.

Insolvency Filing:

Notwithstanding anything to the contrary herein, in the Agreement or in the Definitions, upon any Insolvency Filing in respect of the Issuer, the Transaction shall automatically terminate on the date thereof without further liability of either party to this Confirmation to the other party (except for any liability in respect of any breach of representation or covenant by a party under this Confirmation prior to the date of such Insolvency Filing).

The parties hereto agree and acknowledge that (1) at any point prior to any Insolvency Filing in respect of the Issuer, Party B shall have the unilateral right to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading “Settlement Terms”; and (2) the Transaction shall automatically terminate on the date of any Insolvency Filing pursuant to the provisions set forth in the immediately preceding paragraph only if and to the extent that Party B failed to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading Settlement Terms prior to the relevant Insolvency Filing.

Extraordinary Dividends:

If an ex-dividend date for an Extraordinary Dividend occurs on or after the Trade Date and on or prior to the Maturity Date (or, if later, the last date on which Shares are delivered by Party B to Party A in settlement of the Transaction), Party B shall pay an amount, as determined by the Calculation Agent, in cash equal to the product of such Extraordinary Dividend and the Base Amount to Party A on the earlier of (i) the date on which such Extraordinary Dividend is paid by the Issuer to holders of record of the Shares or (ii) the Maturity Date. “Extraordinary Dividend” means the per Share amount of any cash dividend or distribution declared by the Issuer with respect to the Shares that is specified by the board of directors of the Issuer as an “extraordinary” dividend.

Acceleration Events:

The following events shall each constitute an “Acceleration Event”:

(a) Stock Borrow Events. In the good faith commercially reasonable judgment of Party A (i) Party A (or its Affiliate) is unable to hedge Party A’s exposure to the Transaction because (A) of the lack of sufficient Shares being made available for Share borrowing by lenders, or (B) Party A (or an Affiliate of Party A) would incur a Stock Loan Fee to hedge its exposure to the Transaction that is greater than a rate of 200 basis points per annum (each, a “Stock Borrow Event”);

11

(b) Dividends and Other Distributions. On any day occurring after August 5, 2025 Party B declares a distribution, issue or dividend to existing holders of the Shares of (i) any cash dividend (other than an Extraordinary Dividend) to the extent all cash dividends having an ex-dividend date during the period from and including any Forward Price Reduction Date (with August 5, 2025 being a Forward Price Reduction Date for purposes of this clause (b) only) to but excluding the next subsequent Forward Price Reduction Date exceeds, on a per Share basis, the Forward Price Reduction Amount set forth opposite the first date of any such period on Schedule I or (ii) share capital or securities of another issuer acquired or owned (directly or indirectly) by Party B as a result of a spin-off or other similar transaction or (iii) any other type of securities (other than Shares), rights or warrants or other assets, for payment (cash or other consideration) at less than the prevailing market price as reasonably determined by Party A;

(c) ISDA Early Termination Date. Party A has the right to designate an Early Termination Date pursuant to Section 6 of the Agreement;

(d) Other ISDA Events. The announcement of any event that if consummated, would result in an Extraordinary Event or the occurrence of any Change in Law (other than as specified in clause (Y) of the definition thereof) or a Delisting; provided that in case of a Delisting, in addition to the provisions of Section 12.6(a)(iii) of the 2002 Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, the Nasdaq Global Select Market or the Nasdaq Global Market (or their respective successors); and provided further that the definition of “Change in Law” provided in Section 12.9(a)(ii) of the 2002 Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or public announcement of, the formal or informal interpretation”, (ii) replacing the parenthetical beginning after the word “regulation” in the second line thereof the words “(including, for the avoidance of doubt and without limitation, (x) any tax law or (y) adoption, effectiveness or promulgation of new regulations authorized or mandated by existing statute)” and (iii) immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by Party A on the Trade Date”; or

(e) Ownership Event. In the good faith, reasonable judgment of Party A, on any day, the Share Amount for such day exceeds the Post-Effective Limit for such day (if any applies) (an “Ownership Event”).

For purposes of clause (e) above, the “Share Amount” as of any day is the number of Shares that Party A and any of its Affiliates and any person whose ownership position would be aggregated with that of Party A, including any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part (Party A or any such person or group, a “Party A Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Party B that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership of under any Applicable Restriction, as determined by Party A in its reasonable discretion. The “Post-Effective Limit” means (x) the minimum number of Shares that would give rise to reporting or registration obligations (other than any filing under Section 13 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date) or other requirements (including obtaining prior approval from any person or entity) of a Party A Person, or would result in an adverse effect on a Party A Person, under any Applicable Restriction, as determined by Party A in its reasonable discretion (it being understood that reporting obligations under Section 13 or Section 16 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date, will not be deemed to have an adverse effect), minus (y) 1% of the number of Shares outstanding.

12

Materially Increased Costs:

Upon the occurrence of any Change in Law specified in clause (Y) of the definition thereof, Party A and Party B agree to negotiate in good faith for at least five Exchange Business Days (the “Amendment Period”) to amend this Confirmation to take account of the resulting “materially increased cost” as such phrase is used in clause (Y) of the definition of “Change in Law.” Such amendment may, if agreed by Party A and Party B, result in a Change in Law to which an Acceleration Event applies. If, after negotiating in good faith during the Amendment Period to so amend this Confirmation, Party A and Party B are unable to agree upon such an amendment, the relevant Change in Law specified in clause (Y) of the definition thereof shall constitute an Acceleration Event, notwithstanding any language in clause (d) under the heading “Acceleration Events” above to the contrary. The Calculation Agent may, in connection with a Termination Settlement following such Acceleration Event, reduce the Forward Price to compensate Party A for any “materially increased costs” incurred during the Amendment Period. Any Change in Law that results in Party A (or an Affiliate of Party A) incurring a Stock Loan Fee to hedge its exposure to the Transaction that is equal to or less than a rate equal to 200 basis points per annum shall not constitute a “materially increased cost” for purposes of clause (Y) of the definition of “Change in Law” (but may, for the avoidance of doubt, result in a reduction to the Forward Price pursuant to the provisions opposite the caption “Additional Adjustment” above).

Termination Settlement:

Upon the occurrence of any Acceleration Event, Party A shall have the right to designate, upon at least one Scheduled Trading Day’s notice, any Scheduled Trading Day following such occurrence to be a Settlement Date hereunder (a “Termination Settlement Date”) to which Physical Settlement shall apply, and to select the number of Settlement Shares relating to such Termination Settlement Date; provided that (i) in the case of an Acceleration Event arising out of an Ownership Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares necessary to reduce the Share Amount to the Post-Effective Limit and (ii) in the case of an Acceleration Event arising out of a Stock Borrow Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares as to which such Stock Borrow Event exists. If, upon designation of a Termination Settlement Date by Party A pursuant to the preceding sentence, Party B fails to deliver the Settlement Shares relating to such Termination Settlement Date when due or otherwise fails to perform obligations within its control in respect of the Transaction, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. If an Acceleration Event occurs during an Unwind Period relating to a number of Settlement Shares to which Cash Settlement or Net Share Settlement applies, then on the Termination Settlement Date relating to such Acceleration Event, notwithstanding any election to the contrary by Party B, Cash Settlement or Net Share Settlement shall apply to the portion of the Settlement Shares relating to such Unwind Period as to which Party A has unwound its hedge and Physical Settlement shall apply in respect of (x) the remainder (if any) of such Settlement Shares and (y) the Settlement Shares designated by Party A in respect of such Termination Settlement Date.

Private Placement Procedures:

Notwithstanding anything to the contrary contained in Section 9.11 of the 2002 Definitions, if Party B is unable to comply with the provisions of “Covenant of Party B” above because of a change in law or a change in the policy of the Securities and Exchange Commission or its staff, or Party A otherwise determines that in its reasonable opinion based on the advice of counsel any Settlement Shares to be delivered to Party A by Party B may not be freely returned by Party A or its Affiliates to securities lenders as described under “Covenant of Party B” above, then delivery of any such Settlement Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Party A; provided that Party A may not otherwise determine that the Settlement Shares are Restricted Shares based solely upon Party A or an Affiliate thereof not having borrowed and sold a number of Shares equal to the Base Amount on or before the Effective Date pursuant to the Registration Statement (as defined in the Underwriting Agreement) with delivery of the Prospectus (as defined in the Underwriting Agreement) if there has been no change in law or a change in the policy of the Securities and Exchange Commission or its staff.

Rule 10b5-1:

It is the intent of Party A and Party B that following any election of Cash Settlement or Net Share Settlement by Party B, the purchase of Shares by Party A during any Unwind Period comply with the requirements of Rule 10b5-1(c)(1)(i)(B) of the Exchange Act and that this Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c).

13

Party B acknowledges that (i) during any Unwind Period Party B does not have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares by Party A (or its agent or Affiliate) in connection with this Confirmation and (ii) Party B is entering into the Agreement and this Confirmation in good faith and not as part of a plan or scheme to evade compliance with federal securities laws including, without limitation, Rule 10b-5 promulgated under the Exchange Act, and Party B has acted and will act in good faith with respect to the foregoing.

Party B hereby agrees with Party A that during any Unwind Period Party B shall not communicate, directly or indirectly, any Material Non-Public Information (as defined herein) to any employee of Party A, other than CorpEqDerivSales@wellsfargo.com or any other designee confirmed in writing by Party A. For purposes of the Transaction, “Material Non-Public Information” means information relating to Party B or the Shares that (a) has not been widely disseminated by wire service, in one or more newspapers of general circulation, by communication from Party B to its shareholders or in a press release, contained in a public filing made by Party B with the Securities and Exchange Commission, or otherwise disseminated in a manner permitted by the rules and regulations of the Securities and Exchange Commission, and (b) a reasonable investor might consider to be of importance in making an investment decision to buy, sell or hold Shares. For the avoidance of doubt and solely by way of illustration, information should be presumed “material” if it relates to such matters as dividend increases or decreases, earnings estimates, changes in previously released earnings estimates, significant expansion or curtailment of operations, a significant increase or decline of orders, significant merger or acquisition proposals or agreements, significant new products or discoveries, extraordinary borrowing, major litigation, liquidity problems, extraordinary management developments, purchase or sale of substantial assets, or other similar information.

Maximum Share Delivery:

Notwithstanding any other provision of this Confirmation, in no event will Party B be required to deliver on any Settlement Date, whether pursuant to Physical Settlement, Net Share Settlement, Termination Settlement or any Private Placement Settlement, more than a number of Shares equal to 150% of the initial Base Amount to Party A, subject to reduction by the amount of any Shares delivered by Party B on any prior Settlement Date.

Transfer and Assignment:

Party A may assign or transfer any of its rights or delegate any of its duties hereunder to any Affiliate of Party A that has at the time of such assignment or transfer the same or better creditworthiness as Party A so long as (a) any guarantee of Party A’s obligations hereunder continues to remain in full force and effect with respect to such assignee or transferee, (b) such assignee or transferee is organized under the laws of the United States or any State thereof; (c) Party B will not be required to pay to such assignee or transferee an amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement greater than the amount in respect of which Party B would have been required to pay Party A in the absence of such assignment or transfer; (d) Party B will not receive a payment from which an amount has been withheld or deducted on account of a Tax under Section 2(d)(i) of the Agreement in excess of that which Party A would have been required to so withhold or deduct in the absence of such assignment or transfer, unless Party A would be required to pay to Party B amounts under Section 2(d)(i)(4) of the Agreement in respect of such Tax; (e) no Event of Default, Potential Event of Default, Termination Event, Additional Adjustment or Acceleration Event will occur as a result of such assignment or transfer; (f) prior to such assignment or transfer, Party A shall have caused such assignee or transferee to make such payee tax representations and to provide such tax representations as may be reasonably requested by Party B to permit Party B to determine that the assignment or transfer complies with the requirements of this paragraph; and (g) such assignment or transfer will not cause a deemed exchange for Party B of the Transaction under Section 1001 of the Code (as defined below). Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Party A to purchase, sell, receive or deliver any Shares or other securities to or from Party B, Party A may designate any of its Affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Party A’s obligations in respect of the Transaction and any such designee may assume such obligations. Party A shall be discharged of its obligations to Party B to the extent of any such performance.

14

Indemnity:

Party B agrees to indemnify Party A and its Affiliates and their respective directors, officers, agents and controlling parties (Party A and each such Affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, incurred by or asserted against such Indemnified Party arising out of, in connection with, or relating to, any breach of any covenant or representation made by Party B in this Confirmation or the Agreement and will reimburse any Indemnified Party for all reasonable documented expenses (including reasonable documented legal fees and expenses) in connection with the investigation of, preparation for, or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto, but only to the extent that the relevant loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court of competent jurisdiction to have resulted from such breach. Party B will not be liable under this Indemnity paragraph to the extent that any loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court to have resulted from Party A’s gross negligence, fraud, willful misconduct or breach of this Confirmation or the Agreement.

4. The Agreement is further supplemented by the following provisions:

No Collateral or Setoff:

Notwithstanding Section 6(f) or any other provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Party B hereunder are not secured by any collateral. Obligations under the Transaction shall not be set off against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall be set off against obligations under the Transaction, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (a) separate amounts shall be calculated as set forth in such Section 6(e) with respect to (i) the Transaction and (ii) all other Transactions, and (b) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement.

Status of Claims in Bankruptcy:

Party A acknowledges and agrees that this Confirmation is not intended to convey to Party A rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Party B; provided, however, that nothing herein shall limit or shall be deemed to limit Party A’s right to pursue remedies in the event of a breach by Party B of its obligations and agreements with respect to this Confirmation and the Agreement; and provided further, that nothing herein shall limit or shall be deemed to limit Party A’s rights in respect of any transaction other than the Transaction.

15

Limit on Beneficial Ownership:

Notwithstanding any other provisions hereof, Party A shall not be entitled to take delivery of any Shares deliverable hereunder (whether in connection with the purchase of Shares on any Settlement Date or any Termination Settlement Date, any Private Placement Settlement or otherwise) to the extent (but only to the extent) that, after such receipt of any Shares hereunder, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 9.0%. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 9.0%. If any delivery owed to Party A hereunder is not made, in whole or in part, as a result of this provision, Party B’s obligation to make such delivery shall not be extinguished and Party B shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Party A gives notice to Party B that, after such delivery, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would not exceed the Post-Effective Limit and (ii) the Section 16 Percentage would not exceed 9.0%. The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Party A and any of its Affiliates or any other person subject to aggregation with Party A for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day.

In addition, notwithstanding anything herein to the contrary, if any delivery owed to Party A hereunder is not made, in whole or in part, as a result of the immediately preceding paragraph, Party A shall be permitted to make any payment due in respect of such Shares to Party B in two or more tranches that correspond in amount to the number of Shares delivered by Party B to Party A pursuant to the immediately preceding paragraph.

(a) For the purpose of Section 3(e) of the Agreement, each of Party A and Party B makes the following representation: It is not required by any applicable law, as modified by the practice of any relevant governmental revenue authority, of any Relevant Jurisdiction to make any deduction or withholding for or on account of any Tax from any payment (other than interest under Section 9(h) of the Agreement and any other payments of interest) to be made by it to the other party under the Agreement. In making this representation, it may rely on (i) the accuracy of any representations made by the other party pursuant to Section 3(f) of the Agreement; (ii) the satisfaction of the agreement contained in Section 4(a)(i) or 4(a)(iii) of the Agreement and the accuracy and effectiveness of any document provided by the other party pursuant to Section 4(a)(i) or 4(a)(iii) of the Agreement; and (iii) the satisfaction of the agreement of the other party contained in Section 4(d) of the Agreement; provided that it shall not be a breach of this representation where reliance is placed on clause (ii) of this paragraph and the other party does not deliver a form or document under Section 4(a)(iii) of the Agreement by reason of material prejudice to its legal or commercial position.

For the avoidance of doubt, nothing in this Confirmation shall be interpreted as requiring Party B to deliver cash in respect of the settlement of the Transaction, except in circumstances where the required cash settlement thereof is permitted for classification of the contract as equity by ASC 815-40-25 (formerly EITF 00-19) as in effect on the Trade Date (including, without limitation, where Party B so elects to deliver cash or fails timely to elect to deliver Shares in respect of such settlement). For the avoidance of doubt, the preceding sentence shall not be construed as limiting (i) the Private Placement Procedures set forth in Annex A hereto, (ii) the payment of cash pursuant to the provisions set forth in Section 3 under the heading “Extraordinary Dividends” or (iii) any damages that may be payable by Party B as a result of breach of this Confirmation.

Other Forwards:

Party A acknowledges that Party B has entered into two substantially identical forward transactions for the Shares on the date hereof (the “Other Additional Forwards”) with Mizuho Markets Americas LLC (with Mizuho Securities USA LLC, acting as agent) and JPMorgan Chase Bank, National Association (the “Other Forward Counterparties”). Party A additionally acknowledges that Party B has entered into two substantially identical forward transactions for the Shares with a trade date of August 5, 2025 (the “Other Base Forwards” and, together with the Other Additional Forwards, the “Other Forwards”) with each of the Other Forward Counterparties. Party A and Party B agree that if Party B designates a Settlement Date with respect to any of the Other Forwards and for which Cash Settlement or Net Share Settlement is applicable, and the resulting “Unwind Period” for any such Other Forward coincides for any period of time with an Unwind Period for the Transaction (the “Overlap Unwind Period”), Party B shall give written notice to Party A prior to the commencement of such Overlap Unwind Period (which written notice shall indicate whether the relevant Overlap Unwind Period coincides with an “Unwind Period” under Other Forwards with one or both of the Other Forward Counterparties), and Party A shall only be permitted to purchase Shares to unwind its hedge in respect of the Transaction on, and the resulting Unwind Period shall include only, every second Exchange Business Day that is not a Suspension Day during such Overlap Unwind Period (in the case of an Overlap Unwind Period that coincides with an “Unwind Period” under one or more Other Forwards with one (but only one) of the Other Forward Counterparties), or every third Exchange Business Day that is not a Suspension Day during such Overlap Unwind Period (in the case of an Overlap Unwind Period that coincides with “Unwind Periods” under two or more Other Forwards with both of the Other Forward Counterparties), in each case, as notified by Party B, commencing on the first, second or third Exchange Business Day of such Overlap Unwind Period, as notified by Party B (each such Exchange Business Day on which Party A shall be permitted to purchase Shares in accordance with this paragraph, an “Overlap Observation Day”). For the avoidance of doubt, the operation of this “Other Forwards” provision shall not be deemed to give rise to a Disrupted Day or other adjustment to the Transaction.

ANNEX A

PRIVATE PLACEMENT PROCEDURES

(i) If Party B delivers the Restricted Shares pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Party B shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Party A; provided that if, on or before the date that a Private Placement Settlement would occur, Party B has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(a)(2) of the Securities Act for the sale by Party B to Party A (or any Affiliate designated by Party A) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Party A (or any such Affiliate of Party A) or Party B fails to deliver the Restricted Shares when due or otherwise fails to perform obligations within its control in respect of a Private Placement Settlement, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Party A, due diligence rights (for Party A or any designated buyer of the Restricted Shares by Party A), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Party A. In the case of a Private Placement Settlement, Party A shall, in its good faith discretion, adjust the number of Restricted Shares to be delivered to Party A hereunder in a commercially reasonable manner to reflect the fact that such Restricted Shares may not be freely returned to securities lenders by Party A and may only be saleable by Party A at a discount to reflect the lack of liquidity in Restricted Shares based on actual charges or discounts given. Notwithstanding the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Clearance System Business Day following notice by Party A to Party B of the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Settlement Date or Termination Settlement Date that would otherwise be applicable.

(ii) If Party B delivers any Restricted Shares in respect of the Transaction, Party B agrees that (i) such Shares may be transferred by and among Party A and its Affiliates and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after the applicable Settlement Date, Party B shall promptly remove, or cause the transfer agent for the Shares to remove, any legends referring to any transfer restrictions from such Shares upon delivery by Party A (or such Affiliate of Party A) to Party B or such transfer agent of seller’s and broker’s representation letters customarily delivered by Party A or its Affiliates in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, each without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Party A (or such Affiliate of Party A).

Ladies and Gentlemen,

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the transaction entered into between us on the Trade Date specified below (the “Transaction”). This Confirmation constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.

Each party further agrees that this Confirmation together with the Agreement evidence a complete binding agreement between Party A and Party B as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Party A and Party B had executed an agreement in such form on the Trade Date (but without any Schedule except for (i) the election of the laws of the State of New York as the governing law (without regard to New York’s choice of laws doctrine other than Title 14 of Article 5 of the New York General Obligations Law); (ii) the election of U.S. Dollars as the Termination Currency; (iii) the word “first” shall be replaced with the word “third” each time it occurs in Section 5(a)(i) of the Agreement; and (iv) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Party A as if (a) the phrase “, or becoming capable at such time of being declared,” were deleted from Section 5(a)(vi)(1) of the Agreement, (b) the “Threshold Amount” with respect to Party A were three percent of the shareholders’ equity of Party A’s ultimate parent, (c) the following language were added to the end of Section 5(a)(vi) of the Agreement: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (x) the default was caused solely by error or omission of an administrative or operational nature; (y) funds were available to enable the party to make the payment when due; and (z) the payment is made within one Local Business Day of such party’s receipt of written notice of its failure to pay.”; and (d) the term “Specified Indebtedness” had the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect of deposits received in the ordinary course of a party’s banking business. The parties hereby agree that no Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement. For purposes of the 2002 Definitions, the Transaction is a Share Forward Transaction.

Notice Length:	(a) 30 Scheduled Trading Days, if (x) Party B shall not have designated, on or prior to the date of such Settlement Notice, a Settlement Date under any Other Forward (as defined under “Other Forwards” below) for which Cash Settlement or Net Share Settlement is applicable or (y) Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under one or more Other Forwards for which Cash Settlement or Net Share Settlement is applicable but no Overlap Unwind Period (as defined under “Other Forwards” below) would occur with respect to any Other Forward as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder; or

3

	(b) 60 Scheduled Trading Days, if Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under one or more Other Forwards with one or both of the Other Forward Counterparties for which Cash Settlement or Net Share Settlement is applicable and an Overlap Unwind Period would occur with respect to one or more Other Forwards with one (but only one) Other Forward Counterparty as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder; or
	(c) 90 Scheduled Trading Days, if Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under two or more Other Forwards with both of the Other Forward Counterparties for which Cash Settlement or Net Share Settlement is applicable and an Overlap Unwind Period would occur with respect to two or more Other Forwards with both Other Forward Counterparties as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder.
Settlement Shares:	With respect to any Settlement Date, a number of Shares, not to exceed the Base Amount, designated as such by Party B in the related Settlement Notice or by Party A pursuant to “Termination Settlement” below; provided that on the Maturity Date the number of Settlement Shares shall be equal to the Base Amount on such date.
Settlement Method:	Physical Settlement, Cash Settlement or Net Share Settlement, at the election of Party B as set forth in a Settlement Notice delivered on or after the Effective Date that satisfies the Settlement Notice Requirements; provided that Physical Settlement shall apply (i) if no Settlement Method is validly selected, (ii) with respect to any Settlement Shares in respect of which Party A is unable, in its good faith and commercially reasonable judgment, to unwind its hedge by the end of the Unwind Period in a manner that, in the good faith and commercially reasonable judgment of Party A based upon the advice of counsel, is consistent with the requirements for qualifying for the safe harbor provided by Rule 10b-18 under the Exchange Act or due to the lack of sufficient liquidity in the Shares on any Exchange Business Day during the Unwind Period, or (iii) to any Termination Settlement Date (as defined below under “Termination Settlement”). For the avoidance of doubt, during any Unwind Period, Party B may elect Physical Settlement (as described above) in respect of any Shares that are not Settlement Shares for the Cash Settlement or Net Share Settlement, as the case may be, to which such Unwind Period relates.
	For greater clarity, with respect to any Settlement Date in respect of which Cash Settlement applies, Party A shall be deemed to have completed unwinding its hedge in respect of the portion of the Transaction to be settled on such Settlement Date when it purchases (or, to the extent applicable, unwinds derivative positions (including, but not limited to, swaps or options related to the Shares) resulting in Party A’s synthetic purchase of) an aggregate number of Shares equal to the number of Settlement Shares for such Settlement Date.
Settlement Notice Requirements:	Notwithstanding any other provision hereof, a Settlement Notice delivered by Party B that specifies Cash Settlement or Net Share Settlement will not be effective to establish a Settlement Date or require Cash Settlement or Net Share Settlement unless Party B delivers to Party A with such Settlement Notice a representation signed by Party B substantially in the following form: “As of the date of this Settlement Notice, Party B is not aware of any material nonpublic information concerning itself or the Shares, and is designating the date contained herein as a Settlement Date and is electing Cash Settlement or Net Share Settlement, as the case may be, in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws.”

4

Unwind Period:	Subject to the provisions below under the caption “Other Forwards,” each Exchange Business Day that is not a Suspension Day during the period from and including the first Exchange Business Day following the date Party B validly elects Cash Settlement or Net Share Settlement in respect of a Settlement Date through the Scheduled Trading Day immediately preceding such Settlement Date (or the immediately preceding Exchange Business Day if such Scheduled Trading Day is not an Exchange Business Day); subject to “Termination Settlement” below. If any Exchange Business Day during an Unwind Period is a Disrupted Day, the Calculation Agent shall make commercially reasonable adjustments to the terms of the Transaction (including, without limitation, the Cash Settlement Amount, the number of Net Share Settlement Shares and the 10b-18 VWAP) to account for the occurrence of such Disrupted Day.
Suspension Day:	Any Exchange Business Day on which Party A reasonably determines based on the advice of counsel that Cash Settlement or Net Share Settlement may violate applicable securities laws. Party A shall notify Party B if it receives such advice from its counsel.
Market Disruption Event:	Section 6.3(a) of the 2002 Definitions is hereby amended by replacing clause (ii) in its entirety with “(ii) an Exchange Disruption, or” and inserting immediately following clause (iii) the phrase “; in each case that the Calculation Agent determines is material.”
Exchange Act:	The Securities Exchange Act of 1934, as amended from time to time.
Physical Settlement:	On any Settlement Date in respect of which Physical Settlement applies, Party B shall deliver to Party A through the Clearance System the Settlement Shares for such Settlement Date, and Party A shall pay to Party B, by wire transfer of immediately available funds to an account designated by Party B, an amount in cash equal to the Physical Settlement Amount for such Settlement Date, on a delivery versus payment basis. If, on any Settlement Date, the Shares to be delivered by Party B to Party A hereunder are not so delivered (the “Deferred Shares”), and a Forward Price Reduction Date occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to Party A, then the portion of the Physical Settlement Amount payable by Party A to Party B in respect of the Deferred Shares shall be reduced by an amount equal to the Forward Price Reduction Amount for such Forward Price Reduction Date, multiplied by the number of Deferred Shares.
Physical Settlement Amount:	For any Settlement Date in respect of which Physical Settlement applies, an amount in cash equal to the product of (i) the Forward Price on such Settlement Date and (ii) the number of Settlement Shares for such Settlement Date.
Cash Settlement:	On any Settlement Date in respect of which Cash Settlement applies, if the Cash Settlement Amount for such Settlement Date is a positive number, Party A will pay such Cash Settlement Amount to Party B. If the Cash Settlement Amount is a negative number, Party B will pay the absolute value of such Cash Settlement Amount to Party A. Such amount shall be paid on the Settlement Date by wire transfer of immediately available funds.
Cash Settlement Amount:	For any Settlement Date in respect of which Cash Settlement or Net Share Settlement applies, an amount determined by the Calculation Agent equal to the difference between (1) the product of (i) (A) the average Forward Price over the period beginning on, and including, the date that is one Settlement Cycle following the first day of the applicable Unwind Period and ending on, and including, such Settlement Date (calculated assuming no reduction to the Forward Price for any Forward Price Reduction Date that occurs during the applicable Unwind Period, except as set forth in clause (2) below), minus USD 0.01, minus (B) the average of the 10b-18 VWAP prices per Share on each Exchange Business Day during such Unwind Period (provided that during any Overlap Unwind Period , only those Exchange Business Days that constitute Overlap Observation Days shall be included in such calculation) (clause (B), the “Average Unwind 10b-18 VWAP”), multiplied by (ii) the number of Settlement Shares for such Settlement Date, minus (2) the product of (i) the Forward Price Reduction Amount for any Forward Price Reduction Date that occurs during such Unwind Period, multiplied by (ii) the number of Settlement Shares with respect to which Party A has not unwound its hedge as of such Forward Price Reduction Date.

5

Net Share Settlement:	On any Settlement Date in respect of which Net Share Settlement applies, if the Cash Settlement Amount is a (i) positive number, Party A shall deliver to Party B the Net Share Settlement Shares, or (ii) negative number, Party B shall deliver to Party A the Net Share Settlement Shares; provided that if Party A determines in its good faith judgment that it would be required to deliver Net Share Settlement Shares to Party B, Party A may elect to deliver a portion of such Net Share Settlement Shares on one or more dates prior to the applicable Settlement Date.
Net Share Settlement Shares:	For any Settlement Date in respect of which Net Share Settlement applies, a number of Shares equal to the absolute value of the Cash Settlement Amount divided by the Average Unwind 10b-18 VWAP, with the number of Shares rounded up in the event such calculation results in a fractional number of Shares. If, on any Settlement Date, the Shares to be delivered by Party B or Party A hereunder upon Net Share Settlement are not so delivered (the “Net Share Deferred Shares”), and a Forward Price Reduction Date occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to such party, then the portion of the Net Share Settlement Shares deliverable by Party A or Party B in respect of the Net Share Deferred Shares shall be adjusted by the Calculation Agent to reflect the occurrence of such Forward Price Reduction Amount for such Forward Price Reduction Date.
10b-18 VWAP:	For any Exchange Business Day during the Unwind Period that is not a Suspension Day, the volume-weighted average price at which the Shares trade as reported in the composite transactions for the Exchange on such Exchange Business Day, excluding (i) trades that do not settle regular way, (ii) opening (regular way) reported trades on the Exchange on such Exchange Business Day, (iii) trades that occur in the last ten minutes before the scheduled close of trading on the Exchange on such Exchange Business Day and ten minutes before the scheduled close of the primary trading session in the market where the trade is effected, and (iv) trades on such Exchange Business Day that do not satisfy the requirements of Rule 10b-18(b)(3), as determined in good faith by the Calculation Agent. Party B acknowledges that Party A may refer to the Bloomberg Page “AWK <Equity> AQR SEC” (or any successor thereto), in its discretion, for such Exchange Business Day to determine the 10b-18 VWAP.
Settlement Currency:	USD.
Failure to Deliver:	Inapplicable.
Adjustments:
Extraordinary Events:	The consequences that would otherwise apply under Article 12 of the 2002 Definitions to any applicable Extraordinary Event shall not apply. In lieu of the applicable provisions contained in Article 12 of the 2002 Definitions, the consequences of any Extraordinary Event shall be as specified under the captions “Acceleration Events” and “Termination Settlement” below.
Tender Offer:	Applicable; provided that Section 12.1(d) of the 2002 Definitions shall be amended by replacing the reference therein to “10%” with a reference to “20%”.
Potential Adjustment Event:	The definition of “Potential Adjustment Event” in Section 11.2(e) of the 2002 Definitions shall not include clause (iii) thereof for purposes of the Transaction.

6

	Notwithstanding Section 11.2(e)(v) of the 2002 Definitions, the following repurchases of Shares (if applicable) shall not be considered to be a Potential Adjustment Event:
	(i) Shares withheld from employees of Party B or its Affiliates to pay certain withholding taxes upon the vesting of Share awards or options granted to such employees under compensation or benefit plans of Party B; and
	(ii) Shares purchased in connection with the reinvestment of dividends by recipients of Share awards under Party B’s compensation or benefit plans; and
	(iii) Shares purchased in connection with the operation of Party B’s dividend reinvestment and direct stock purchase plans;
	(iv) Shares purchased by Party B to offset any shareholder dilution arising from the exercise of options to purchase Shares; and
	(v) Up to 1,000,000 Shares purchased subsequent to the Trade Date under Party B’s publicly announced share repurchase program.

Method of Adjustment:	Calculation Agent Adjustment; notwithstanding anything in the 2002 Definitions to the contrary, the Calculation Agent may make an adjustment pursuant to Calculation Agent Adjustment to any one or more of the Base Amount, the Forward Price and any other variable relevant to the settlement or payment terms of the Transaction.
Additional Adjustment:	If, in Party A’s good faith and commercially reasonable judgment, the stock loan fee to Party A (or an Affiliate thereof), excluding the federal funds rate (or other interest rate) component payable by the relevant stock lender to Party A or such Affiliate (the “Stock Loan Fee”), over any one month period (or, in respect of any day from, and including, the Trade Date to, but excluding, the date that is one month following the Trade Date, over the period of days as have elapsed from, and including, the Trade Date to, and including, such day), of borrowing a number of Shares equal to the Base Amount to hedge its exposure to the Transaction exceeds a weighted average rate equal to 50 basis points per annum, the Calculation Agent shall reduce the Forward Price in order to compensate Party A for the amount by which the Stock Loan Fee exceeded a weighted average rate equal to 50 basis points per annum during such period. The Calculation Agent shall notify Party B prior to making any such adjustment to the Forward Price and, upon the request of Party B, Party A shall provide an itemized list of the Stock Loan Fees for the applicable period specified above in this paragraph.

The “Base Amount Percentage” as of any day is the fraction (1) the numerator of which is the sum of (i) the Base Amount, and (ii) the “Base Amount,” as such term is defined in the confirmation dated as of August 4, 2025 between Party A and Party B relating to a substantially identical forward transaction with respect to 2,347,418 Shares (the “Base Confirmation”) and (2) the denominator of which is the number of Shares outstanding on such day.

(d) No filing with, or approval, authorization, consent, license, registration, qualification, order or decree of, any court or governmental authority or agency, domestic or foreign, is necessary or required for the execution, delivery and performance by Party B of this Confirmation and the consummation of the Transaction (including, without limitation, the issuance and delivery of Shares on any Settlement Date) except (i) such as have been obtained under the Securities Act of 1933, as amended (the “Securities Act”), and (ii) as may be required to be obtained under state securities laws.

(e) Party B agrees not to make any Issuer Repurchase if, immediately following such Issuer Repurchase, the Base Amount Percentage would be equal to or greater than 9.0%.

(f) Party B is not insolvent, nor will Party B be rendered insolvent as a result of the Transaction.

(g) Neither Party B nor any of its Affiliates shall take or refrain from taking any action (including, without limitation, any direct purchases by Party B or any of its Affiliates or any purchases by a party to a derivative transaction with Party B or any of its Affiliates), either under this Confirmation, under an agreement with another party or otherwise, that Party B reasonably believes would cause any purchases of Shares by Party A or any of its Affiliates in connection with any Cash Settlement or Net Share Settlement of the Transaction not to meet the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act if such purchases were made by Party B.

(h) Party B will not engage in any “distribution” (as defined in Regulation M under the Exchange Act (“Regulation M”)) that would cause a “restricted period” (as defined in Regulation M) to occur during any Unwind Period.

9

(i) Party B is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended).

(j) In addition to any other requirements set forth herein, Party B agrees not to elect Cash Settlement or Net Share Settlement if, in the reasonable judgment of either Party A or Party B, such settlement or Party A’s related market activity would result in a violation of the U.S. federal securities laws or any other federal or state law or regulation applicable to Party B.

(k) Party B (i) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (ii) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (iii) has total assets of at least USD 50 million as of the date hereof.

(l) Party B acknowledges and agrees that:

(i) during the term of the Transaction, Party A and its Affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to establish, adjust or unwind its hedge position with respect to the Transaction;

(ii) Party A and its Affiliates may also be active in the market for the Shares and Share-linked transactions other than in connection with hedging activities in relation to the Transaction;

(iii) Party A shall make its own determination as to whether, when or in what manner any hedging or market activities in Party B’s securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Forward Price and the 10b-18 VWAP;

(iv) any market activities of Party A and its Affiliates with respect to the Shares may affect the market price and volatility of the Shares, as well as the Forward Price and 10b-18 VWAP, each in a manner that may be adverse to Party B; and

(v) the Transaction is a derivatives transaction in which it has granted Party A the right, under certain circumstances, to receive cash or Shares, as the case may be; Party A may purchase Shares for its own account at an average price that may be greater than, or less than, the effective price paid by Party B under the terms of the Transaction.

(m) Party B will notify Party A within five Exchange Business Days of obtaining knowledge of the occurrence of any event that would constitute a Potential Adjustment Event (or, if earlier, the date on which it publicly discloses such Potential Adjustment Event).

Covenant of Party B:

Subject to the provisions of “Private Placement Procedures” below, the parties acknowledge and agree that any Shares delivered by Party B to Party A on any Settlement Date will be newly issued Shares and when delivered by Party A (or an Affiliate of Party A) to securities lenders from whom Party A (or an Affiliate of Party A) borrowed Shares in connection with hedging its exposure to the Transaction will be freely saleable without further registration or other restrictions under the Securities Act, in the hands of those securities lenders (provided that such Shares may be subject to restrictions if the status of any such securities lender would cause any such resale restrictions to apply by virtue of such securities lender’s share ownership in Party B, status as an Affiliate of Party B or otherwise), irrespective of whether such stock loan is effected by Party A or an Affiliate of Party A. Accordingly, subject to the provisions of “Private Placement Procedures” below, Party B agrees that the Shares that it delivers to Party A on each Settlement Date will not bear a restrictive legend and that such Shares will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System.

10

Covenants of Party A:

(a) Unless the provisions set forth below under “Private Placement Procedures” shall be applicable, Party A shall use any Shares delivered by Party B to Party A on any Settlement Date to return Shares to securities lenders to close out open Share loans created by Party A or an Affiliate of Party A in the course of Party A’s or such Affiliate’s hedging activities related to Party A’s exposure under this Confirmation.

(b) In connection with bids and purchases of Shares in connection with any Cash Settlement or Net Share Settlement of the Transaction, Party A shall use its commercially reasonable efforts to conduct its activities, or cause its Affiliates to conduct their activities, in a manner consistent with the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act, as if such provisions were applicable to such purchases.

Insolvency Filing:

Notwithstanding anything to the contrary herein, in the Agreement or in the Definitions, upon any Insolvency Filing in respect of the Issuer, the Transaction shall automatically terminate on the date thereof without further liability of either party to this Confirmation to the other party (except for any liability in respect of any breach of representation or covenant by a party under this Confirmation prior to the date of such Insolvency Filing).

The parties hereto agree and acknowledge that (1) at any point prior to any Insolvency Filing in respect of the Issuer, Party B shall have the unilateral right to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading “Settlement Terms”; and (2) the Transaction shall automatically terminate on the date of any Insolvency Filing pursuant to the provisions set forth in the immediately preceding paragraph only if and to the extent that Party B failed to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading Settlement Terms prior to the relevant Insolvency Filing.

Extraordinary Dividends:

If an ex-dividend date for an Extraordinary Dividend occurs on or after the Trade Date and on or prior to the Maturity Date (or, if later, the last date on which Shares are delivered by Party B to Party A in settlement of the Transaction), Party B shall pay an amount, as determined by the Calculation Agent, in cash equal to the product of such Extraordinary Dividend and the Base Amount to Party A on the earlier of (i) the date on which such Extraordinary Dividend is paid by the Issuer to holders of record of the Shares or (ii) the Maturity Date. “Extraordinary Dividend” means the per Share amount of any cash dividend or distribution declared by the Issuer with respect to the Shares that is specified by the board of directors of the Issuer as an “extraordinary” dividend.

Acceleration Events:

The following events shall each constitute an “Acceleration Event”:

(a) Stock Borrow Events. In the good faith commercially reasonable judgment of Party A (i) Party A (or its Affiliate) is unable to hedge Party A’s exposure to the Transaction because (A) of the lack of sufficient Shares being made available for Share borrowing by lenders, or (B) Party A (or an Affiliate of Party A) would incur a Stock Loan Fee to hedge its exposure to the Transaction that is greater than a rate of 200 basis points per annum (each, a “Stock Borrow Event”);

11

(b) Dividends and Other Distributions. On any day occurring after August 5, 2025 Party B declares a distribution, issue or dividend to existing holders of the Shares of (i) any cash dividend (other than an Extraordinary Dividend) to the extent all cash dividends having an ex-dividend date during the period from and including any Forward Price Reduction Date (with August 5, 2025 being a Forward Price Reduction Date for purposes of this clause (b) only) to but excluding the next subsequent Forward Price Reduction Date exceeds, on a per Share basis, the Forward Price Reduction Amount set forth opposite the first date of any such period on Schedule I or (ii) share capital or securities of another issuer acquired or owned (directly or indirectly) by Party B as a result of a spin-off or other similar transaction or (iii) any other type of securities (other than Shares), rights or warrants or other assets, for payment (cash or other consideration) at less than the prevailing market price as reasonably determined by Party A;

(c) ISDA Early Termination Date. Party A has the right to designate an Early Termination Date pursuant to Section 6 of the Agreement;

(d) Other ISDA Events. The announcement of any event that if consummated, would result in an Extraordinary Event or the occurrence of any Change in Law (other than as specified in clause (Y) of the definition thereof) or a Delisting; provided that in case of a Delisting, in addition to the provisions of Section 12.6(a)(iii) of the 2002 Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, the Nasdaq Global Select Market or the Nasdaq Global Market (or their respective successors); and provided further that the definition of “Change in Law” provided in Section 12.9(a)(ii) of the 2002 Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or public announcement of, the formal or informal interpretation”, (ii) replacing the parenthetical beginning after the word “regulation” in the second line thereof the words “(including, for the avoidance of doubt and without limitation, (x) any tax law or (y) adoption, effectiveness or promulgation of new regulations authorized or mandated by existing statute)” and (iii) immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by Party A on the Trade Date”; or

(e) Ownership Event. In the good faith, reasonable judgment of Party A, on any day, the Share Amount for such day exceeds the Post-Effective Limit for such day (if any applies) (an “Ownership Event”).

For purposes of clause (e) above, the “Share Amount” as of any day is the number of Shares that Party A and any of its Affiliates and any person whose ownership position would be aggregated with that of Party A, including any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part (Party A or any such person or group, a “Party A Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Party B that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership of under any Applicable Restriction, as determined by Party A in its reasonable discretion. The “Post-Effective Limit” means (x) the minimum number of Shares that would give rise to reporting or registration obligations (other than any filing under Section 13 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date) or other requirements (including obtaining prior approval from any person or entity) of a Party A Person, or would result in an adverse effect on a Party A Person, under any Applicable Restriction, as determined by Party A in its reasonable discretion (it being understood that reporting obligations under Section 13 or Section 16 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date, will not be deemed to have an adverse effect), minus (y) 1% of the number of Shares outstanding.

Materially Increased Costs:

Upon the occurrence of any Change in Law specified in clause (Y) of the definition thereof, Party A and Party B agree to negotiate in good faith for at least five Exchange Business Days (the “Amendment Period”) to amend this Confirmation to take account of the resulting “materially increased cost” as such phrase is used in clause (Y) of the definition of “Change in Law.” Such amendment may, if agreed by Party A and Party B,

12

result in a Change in Law to which an Acceleration Event applies. If, after negotiating in good faith during the Amendment Period to so amend this Confirmation, Party A and Party B are unable to agree upon such an amendment, the relevant Change in Law specified in clause (Y) of the definition thereof shall constitute an Acceleration Event, notwithstanding any language in clause (d) under the heading “Acceleration Events” above to the contrary. The Calculation Agent may, in connection with a Termination Settlement following such Acceleration Event, reduce the Forward Price to compensate Party A for any “materially increased costs” incurred during the Amendment Period. Any Change in Law that results in Party A (or an Affiliate of Party A) incurring a Stock Loan Fee to hedge its exposure to the Transaction that is equal to or less than a rate equal to 200 basis points per annum shall not constitute a “materially increased cost” for purposes of clause (Y) of the definition of “Change in Law” (but may, for the avoidance of doubt, result in a reduction to the Forward Price pursuant to the provisions opposite the caption “Additional Adjustment” above).

Termination Settlement:

Upon the occurrence of any Acceleration Event, Party A shall have the right to designate, upon at least one Scheduled Trading Day’s notice, any Scheduled Trading Day following such occurrence to be a Settlement Date hereunder (a “Termination Settlement Date”) to which Physical Settlement shall apply, and to select the number of Settlement Shares relating to such Termination Settlement Date; provided that (i) in the case of an Acceleration Event arising out of an Ownership Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares necessary to reduce the Share Amount to the Post-Effective Limit and (ii) in the case of an Acceleration Event arising out of a Stock Borrow Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares as to which such Stock Borrow Event exists. If, upon designation of a Termination Settlement Date by Party A pursuant to the preceding sentence, Party B fails to deliver the Settlement Shares relating to such Termination Settlement Date when due or otherwise fails to perform obligations within its control in respect of the Transaction, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. If an Acceleration Event occurs during an Unwind Period relating to a number of Settlement Shares to which Cash Settlement or Net Share Settlement applies, then on the Termination Settlement Date relating to such Acceleration Event, notwithstanding any election to the contrary by Party B, Cash Settlement or Net Share Settlement shall apply to the portion of the Settlement Shares relating to such Unwind Period as to which Party A has unwound its hedge and Physical Settlement shall apply in respect of (x) the remainder (if any) of such Settlement Shares and (y) the Settlement Shares designated by Party A in respect of such Termination Settlement Date.

Private Placement Procedures:

Notwithstanding anything to the contrary contained in Section 9.11 of the 2002 Definitions, if Party B is unable to comply with the provisions of “Covenant of Party B” above because of a change in law or a change in the policy of the Securities and Exchange Commission or its staff, or Party A otherwise determines that in its reasonable opinion based on the advice of counsel any Settlement Shares to be delivered to Party A by Party B may not be freely returned by Party A or its Affiliates to securities lenders as described under “Covenant of Party B” above, then delivery of any such Settlement Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Party A; provided that Party A may not otherwise determine that the Settlement Shares are Restricted Shares based solely upon Party A or an Affiliate thereof not having borrowed and sold a number of Shares equal to the Base Amount on or before the Effective Date pursuant to the Registration Statement (as defined in the Underwriting Agreement) with delivery of the Prospectus (as defined in the Underwriting Agreement) if there has been no change in law or a change in the policy of the Securities and Exchange Commission or its staff.

Rule 10b5-1:

It is the intent of Party A and Party B that following any election of Cash Settlement or Net Share Settlement by Party B, the purchase of Shares by Party A during any Unwind Period comply with the requirements of Rule 10b5-1(c)(1)(i)(B) of the Exchange Act and that this Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c).

13

Party B acknowledges that (i) during any Unwind Period Party B does not have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares by Party A (or its agent or Affiliate) in connection with this Confirmation and (ii) Party B is entering into the Agreement and this Confirmation in good faith and not as part of a plan or scheme to evade compliance with federal securities laws including, without limitation, Rule 10b-5 promulgated under the Exchange Act, and Party B has acted and will act in good faith with respect to the foregoing.

Party B hereby agrees with Party A that during any Unwind Period Party B shall not communicate, directly or indirectly, any Material Non-Public Information (as defined herein) to any EDG Personnel. “EDG Personnel” means any employee on the trading side of the Equity Derivatives Group of J.P. Morgan Securities LLC and does not include Mr. David Aidelson, Mr. Elliot Chalom, Mr. Noah L. Wynkoop, Ms. Yana Chernobilsky, Mr. Ganaraj S. Hegde, and Mr. Gaurav Maria (or any other person or persons designated from time to time by the Compliance Group of Party A). For purposes of the Transaction, “Material Non-Public Information” means information relating to Party B or the Shares that (a) has not been widely disseminated by wire service, in one or more newspapers of general circulation, by communication from Party B to its shareholders or in a press release, contained in a public filing made by Party B with the Securities and Exchange Commission, or otherwise disseminated in a manner permitted by the rules and regulations of the Securities and Exchange Commission, and (b) a reasonable investor might consider to be of importance in making an investment decision to buy, sell or hold Shares. For the avoidance of doubt and solely by way of illustration, information should be presumed “material” if it relates to such matters as dividend increases or decreases, earnings estimates, changes in previously released earnings estimates, significant expansion or curtailment of operations, a significant increase or decline of orders, significant merger or acquisition proposals or agreements, significant new products or discoveries, extraordinary borrowing, major litigation, liquidity problems, extraordinary management developments, purchase or sale of substantial assets, or other similar information.

Maximum Share Delivery:

Notwithstanding any other provision of this Confirmation, in no event will Party B be required to deliver on any Settlement Date, whether pursuant to Physical Settlement, Net Share Settlement, Termination Settlement or any Private Placement Settlement, more than a number of Shares equal to 150% of the initial Base Amount to Party A, subject to reduction by the amount of any Shares delivered by Party B on any prior Settlement Date.

Transfer and Assignment:

Party A may assign or transfer any of its rights or delegate any of its duties hereunder to any Affiliate of Party A that has at the time of such assignment or transfer the same or better creditworthiness as Party A so long as (a) any guarantee of Party A’s obligations hereunder continues to remain in full force and effect with respect to such assignee or transferee, (b) such assignee or transferee is organized under the laws of the United States or any State thereof; (c) Party B will not be required to pay to such assignee or transferee an amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement greater than the amount in respect of which Party B would have been required to pay Party A in the absence of such assignment or transfer; (d) Party B will not receive a payment from which an amount has been withheld or deducted on account of a Tax under Section 2(d)(i) of the Agreement in excess of that which Party A would have been required to so withhold or deduct in the absence of such assignment or transfer, unless Party A would be required to pay to Party B amounts under Section 2(d)(i)(4) of the Agreement in respect of such Tax; (e) no Event of Default, Potential Event of Default, Termination Event, Additional Adjustment or Acceleration Event will occur as a result of such assignment or transfer; (f) prior to such assignment or transfer, Party A shall have caused such assignee or transferee to make such payee tax representations and to provide such tax representations as may be reasonably requested by Party B to permit Party B to determine that the assignment or transfer complies with the requirements of this paragraph; and (g) such assignment or transfer will not cause a deemed exchange for Party B of the Transaction under Section 1001 of the Code (as defined below). Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Party A to purchase, sell, receive or deliver any Shares or other securities to or from Party B, Party A may designate any of its Affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Party A’s obligations in respect of the Transaction and any such designee may assume such obligations. Party A shall be discharged of its obligations to Party B to the extent of any such performance.

14

Indemnity:

Party B agrees to indemnify Party A and its Affiliates and their respective directors, officers, agents and controlling parties (Party A and each such Affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, incurred by or asserted against such Indemnified Party arising out of, in connection with, or relating to, any breach of any covenant or representation made by Party B in this Confirmation or the Agreement and will reimburse any Indemnified Party for all reasonable documented expenses (including reasonable documented legal fees and expenses) in connection with the investigation of, preparation for, or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto, but only to the extent that the relevant loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court of competent jurisdiction to have resulted from such breach. Party B will not be liable under this Indemnity paragraph to the extent that any loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court to have resulted from Party A’s gross negligence, fraud, willful misconduct or breach of this Confirmation or the Agreement.

4. The Agreement is further supplemented by the following provisions:

No Collateral or Setoff:

Notwithstanding Section 6(f) or any other provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Party B hereunder are not secured by any collateral. Obligations under the Transaction shall not be set off against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall be set off against obligations under the Transaction, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (a) separate amounts shall be calculated as set forth in such Section 6(e) with respect to (i) the Transaction and (ii) all other Transactions, and (b) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement.

Status of Claims in Bankruptcy:

Party A acknowledges and agrees that this Confirmation is not intended to convey to Party A rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Party B; provided, however, that nothing herein shall limit or shall be deemed to limit Party A’s right to pursue remedies in the event of a breach by Party B of its obligations and agreements with respect to this Confirmation and the Agreement; and provided further, that nothing herein shall limit or shall be deemed to limit Party A’s rights in respect of any transaction other than the Transaction.

15

Limit on Beneficial Ownership:

Notwithstanding any other provisions hereof, Party A shall not be entitled to take delivery of any Shares deliverable hereunder (whether in connection with the purchase of Shares on any Settlement Date or any Termination Settlement Date, any Private Placement Settlement or otherwise) to the extent (but only to the extent) that, after such receipt of any Shares hereunder, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 9.0%. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 9.0%. If any delivery owed to Party A hereunder is not made, in whole or in part, as a result of this provision, Party B’s obligation to make such delivery shall not be extinguished and Party B shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Party A gives notice to Party B that, after such delivery, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would not exceed the Post-Effective Limit and (ii) the Section 16 Percentage would not exceed 9.0%. The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Party A and any of its Affiliates or any other person subject to aggregation with Party A for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day.

In addition, notwithstanding anything herein to the contrary, if any delivery owed to Party A hereunder is not made, in whole or in part, as a result of the immediately preceding paragraph, Party A shall be permitted to make any payment due in respect of such Shares to Party B in two or more tranches that correspond in amount to the number of Shares delivered by Party B to Party A pursuant to the immediately preceding paragraph.

Wall Street Transparency and Accountability Act:

In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (the “WSTAA”), the parties hereby agree that neither the enactment of the WSTAA or any regulation under the WSTAA, nor any requirement under the WSTAA or an amendment made by the WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from any Acceleration Event or Illegality (as defined in the Agreement)).

(b) Waiver of Right to Trial by Jury. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to this Confirmation. Each party (i) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of such a suit action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into this Confirmation by, among other things, the mutual waivers and certifications herein.

Acknowledgements:

The parties hereto intend for:

(a) the Transaction to be a “securities contract” as defined in Section 741(7) of Title 11 of the United States Code (the “Bankruptcy Code”), qualifying for the protections under Section 555 of the Bankruptcy Code;

(b) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as defined in the Bankruptcy Code;

(c) Party A to be a “financial institution” within the meaning of Section 101(22) of the Bankruptcy Code; and

(d) all payments for, under or in connection with the Transaction, all payments for the Shares and the transfer of such Shares to constitute “settlement payments” as defined in the Bankruptcy Code.

If Party A is a bank regulated by the Federal Deposit Insurance Corporation, (i) Party A recognizes and intends that the Transaction is, and shall constitute, a “qualified financial contract” as that term is defined in 12 U.S.C. §1821(e)(8)(D)(i), as the same may be amended, modified, or supplemented from time to time; and (ii) Party A represents and warrants that it is authorized by appropriate corporate action under applicable law to enter into the Transaction as evidenced by the execution hereof by an officer of Party A at the level of vice president or higher.

Severability:

If any term, provision, covenant or condition of this Confirmation, or the application thereof to any party or circumstance, shall be held to be invalid or unenforceable in whole or in part for any reason, the remaining terms, provisions, covenants, and conditions hereof shall continue in full force and effect as if this Confirmation had been executed with the invalid or unenforceable provision eliminated, so long as this

17

Confirmation as so modified continues to express, without material change, the original intentions of the parties as to the subject matter of this Confirmation and the deletion of such portion of this Confirmation will not substantially impair the respective benefits or expectations of parties to the Agreement; provided, however, that this severability provision shall not be applicable if any provision of Section 2, 5, 6 or 13 of the Agreement (or any definition or provision in Section 14 to the extent that it relates to, or is used in or in connection with any such Section) shall be so held to be invalid or unenforceable.

Tax Matters:

Party A and Party B agree that if Party B designates a Settlement Date with respect to any of the Other Forwards and for which Cash Settlement or Net Share Settlement is applicable, and the resulting “Unwind Period” for any such Other Forward coincides for any period of time with an Unwind Period for the Transaction (the “Overlap Unwind Period”), Party B shall give written notice to Party A prior to the commencement of such Overlap Unwind Period (which written notice shall indicate whether the relevant Overlap Unwind Period coincides with an “Unwind Period” under Other Forwards with one or both of the Other Forward Counterparties), and Party A shall only be permitted to purchase Shares to unwind its hedge in respect of the Transaction on, and the resulting Unwind Period shall include only, every second Exchange Business Day that is not a Suspension Day during such Overlap Unwind Period (in the case of an Overlap Unwind Period that coincides with an “Unwind Period” under one or more Other Forwards with one (but only one) of the Other Forward Counterparties), or every third Exchange Business Day that is not a Suspension Day during such Overlap Unwind Period (in the case of an Overlap Unwind Period that coincides with “Unwind Periods” under two or more Other Forwards with both of the Other Forward Counterparties), in each case, as notified by Party B, commencing on the first, second or third Exchange Business Day of such Overlap Unwind Period, as notified by Party B (each such Exchange Business Day on which Party A shall be permitted to purchase Shares in accordance with this paragraph, an “Overlap Observation Day”). For the avoidance of doubt, the operation of this “Other Forwards” provision shall not be deemed to give rise to a Disrupted Day or other adjustment to the Transaction.

Morgan Securities LLC with respect to the Transaction, Party B is hereby notified that such employee will act solely as an authorized representative of JPMorgan Chase Bank, N.A.

ANNEX A

PRIVATE PLACEMENT PROCEDURES

(i) If Party B delivers the Restricted Shares pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Party B shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Party A; provided that if, on or before the date that a Private Placement Settlement would occur, Party B has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(a)(2) of the Securities Act for the sale by Party B to Party A (or any Affiliate designated by Party A) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Party A (or any such Affiliate of Party A) or Party B fails to deliver the Restricted Shares when due or otherwise fails to perform obligations within its control in respect of a Private Placement Settlement, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Party A, due diligence rights (for Party A or any designated buyer of the Restricted Shares by Party A), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Party A. In the case of a Private Placement Settlement, Party A shall, in its good faith discretion, adjust the number of Restricted Shares to be delivered to Party A hereunder in a commercially reasonable manner to reflect the fact that such Restricted Shares may not be freely returned to securities lenders by Party A and may only be saleable by Party A at a discount to reflect the lack of liquidity in Restricted Shares based on actual charges or discounts given. Notwithstanding the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Clearance System Business Day following notice by Party A to Party B of the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Settlement Date or Termination Settlement Date that would otherwise be applicable.

(ii) If Party B delivers any Restricted Shares in respect of the Transaction, Party B agrees that (i) such Shares may be transferred by and among Party A and its Affiliates and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after the applicable Settlement Date, Party B shall promptly remove, or cause the transfer agent for the Shares to remove, any legends referring to any transfer restrictions from such Shares upon delivery by Party A (or such Affiliate of Party A) to Party B or such transfer agent of seller’s and broker’s representation letters customarily delivered by Party A or its Affiliates in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, each without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Party A (or such Affiliate of Party A).

3

Notice Length:	(a) 30 Scheduled Trading Days, if (x) Party B shall not have designated, on or prior to the date of such Settlement Notice, a Settlement Date under any Other Forward (as defined under “Other Forwards” below) for which Cash Settlement or Net Share Settlement is applicable or (y) Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under one or more Other Forwards for which Cash Settlement or Net Share Settlement is applicable but no Overlap Unwind Period (as defined under “Other Forwards” below) would occur with respect to any Other Forward as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder; or
	(b) 60 Scheduled Trading Days, if Party B shall have designated, on or prior to the date of such Settlement Notice, a Settlement Date under one or more Other Forwards with one or both of the Other Forward Counterparties for which Cash Settlement or Net Share Settlement is applicable and an Overlap Unwind Period would occur with respect to one or more Other Forwards with one (but only one) Other Forward Counterparty as a result of the election of Cash Settlement or Net Share Settlement, as the case may be, hereunder; or

Settlement Shares:	With respect to any Settlement Date, a number of Shares, not to exceed the Base Amount, designated as such by Party B in the related Settlement Notice or by Party A pursuant to “Termination Settlement” below; provided that on the Maturity Date the number of Settlement Shares shall be equal to the Base Amount on such date.
Settlement Method:	Physical Settlement, Cash Settlement or Net Share Settlement, at the election of Party B as set forth in a Settlement Notice delivered on or after the Effective Date that satisfies the Settlement Notice Requirements; provided that Physical Settlement shall apply (i) if no Settlement Method is validly selected, (ii) with respect to any Settlement Shares in respect of which Party A is unable, in its good faith and commercially reasonable judgment, to unwind its hedge by the end of the Unwind Period in a manner that, in the good faith and commercially reasonable judgment of Party A based upon the advice of counsel, is consistent with the requirements for qualifying for the safe harbor provided by Rule 10b-18 under the Exchange Act or due to the lack of sufficient liquidity in the Shares on any Exchange Business Day during the Unwind Period, or (iii) to any Termination Settlement Date (as defined below under “Termination Settlement”). For the avoidance of doubt, during any Unwind Period, Party B may elect Physical Settlement (as described above) in respect of any Shares that are not Settlement Shares for the Cash Settlement or Net Share Settlement, as the case may be, to which such Unwind Period relates.
	For greater clarity, with respect to any Settlement Date in respect of which Cash Settlement applies, Party A shall be deemed to have completed unwinding its hedge in respect of the portion of the Transaction to be settled on such Settlement Date when it purchases (or, to the extent applicable, unwinds derivative positions (including, but not limited to, swaps or options related to the Shares) resulting in Party A’s synthetic purchase of) an aggregate number of Shares equal to the number of Settlement Shares for such Settlement Date.

4

Settlement Notice Requirements:	Notwithstanding any other provision hereof, a Settlement Notice delivered by Party B that specifies Cash Settlement or Net Share Settlement will not be effective to establish a Settlement Date or require Cash Settlement or Net Share Settlement unless Party B delivers to Party A with such Settlement Notice a representation signed by Party B substantially in the following form: “As of the date of this Settlement Notice, Party B is not aware of any material nonpublic information concerning itself or the Shares, and is designating the date contained herein as a Settlement Date and is electing Cash Settlement or Net Share Settlement, as the case may be, in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws.”
Unwind Period:	Subject to the provisions below under the caption “Other Forwards,” each Exchange Business Day that is not a Suspension Day during the period from and including the first Exchange Business Day following the date Party B validly elects Cash Settlement or Net Share Settlement in respect of a Settlement Date through the Scheduled Trading Day immediately preceding such Settlement Date (or the immediately preceding Exchange Business Day if such Scheduled Trading Day is not an Exchange Business Day); subject to “Termination Settlement” below. If any Exchange Business Day during an Unwind Period is a Disrupted Day, the Calculation Agent shall make commercially reasonable adjustments to the terms of the Transaction (including, without limitation, the Cash Settlement Amount, the number of Net Share Settlement Shares and the 10b-18 VWAP) to account for the occurrence of such Disrupted Day.
Suspension Day:	Any Exchange Business Day on which Party A reasonably determines based on the advice of counsel that Cash Settlement or Net Share Settlement may violate applicable securities laws. Party A shall notify Party B if it receives such advice from its counsel.
Market Disruption Event:	Section 6.3(a) of the 2002 Definitions is hereby amended by replacing clause (ii) in its entirety with “(ii) an Exchange Disruption, or” and inserting immediately following clause (iii) the phrase “; in each case that the Calculation Agent determines is material.”
Exchange Act:	The Securities Exchange Act of 1934, as amended from time to time.
Physical Settlement:	On any Settlement Date in respect of which Physical Settlement applies, Party B shall deliver to Party A through the Clearance System the Settlement Shares for such Settlement Date, and Party A shall pay to Party B, by wire transfer of immediately available funds to an account designated by Party B, an amount in cash equal to the Physical Settlement Amount for such Settlement Date, on a delivery versus payment basis. If, on any Settlement Date, the Shares to be delivered by Party B to Party A hereunder are not so delivered (the “Deferred Shares”), and a Forward Price Reduction Date occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to Party A, then the portion of the Physical Settlement Amount payable by Party A to Party B in respect of the Deferred Shares shall be reduced by an amount equal to the Forward Price Reduction Amount for such Forward Price Reduction Date, multiplied by the number of Deferred Shares.
Physical Settlement Amount:	For any Settlement Date in respect of which Physical Settlement applies, an amount in cash equal to the product of (i) the Forward Price on such Settlement Date and (ii) the number of Settlement Shares for such Settlement Date.
Cash Settlement:	On any Settlement Date in respect of which Cash Settlement applies, if the Cash Settlement Amount for such Settlement Date is a positive number, Party A will pay such Cash Settlement Amount to Party B. If the Cash Settlement Amount is a negative number, Party B will pay the absolute value of such Cash Settlement Amount to Party A. Such amount shall be paid on the Settlement Date by wire transfer of immediately available funds.

5

Cash Settlement Amount:	For any Settlement Date in respect of which Cash Settlement or Net Share Settlement applies, an amount determined by the Calculation Agent equal to the difference between (1) the product of (i) (A) the average Forward Price over the period beginning on, and including, the date that is one Settlement Cycle following the first day of the applicable Unwind Period and ending on, and including, such Settlement Date (calculated assuming no reduction to the Forward Price for any Forward Price Reduction Date that occurs during the applicable Unwind Period, except as set forth in clause (2) below), minus USD 0.01, minus (B) the average of the 10b-18 VWAP prices per Share on each Exchange Business Day during such Unwind Period (provided that during any Overlap Unwind Period , only those Exchange Business Days that constitute Overlap Observation Days shall be included in such calculation) (clause (B), the “Average Unwind 10b-18 VWAP”), multiplied by (ii) the number of Settlement Shares for such Settlement Date, minus (2) the product of (i) the Forward Price Reduction Amount for any Forward Price Reduction Date that occurs during such Unwind Period, multiplied by (ii) the number of Settlement Shares with respect to which Party A has not unwound its hedge as of such Forward Price Reduction Date.
Net Share Settlement:	On any Settlement Date in respect of which Net Share Settlement applies, if the Cash Settlement Amount is a (i) positive number, Party A shall deliver to Party B the Net Share Settlement Shares, or (ii) negative number, Party B shall deliver to Party A the Net Share Settlement Shares; provided that if Party A determines in its good faith judgment that it would be required to deliver Net Share Settlement Shares to Party B, Party A may elect to deliver a portion of such Net Share Settlement Shares on one or more dates prior to the applicable Settlement Date.
Net Share Settlement Shares:	For any Settlement Date in respect of which Net Share Settlement applies, a number of Shares equal to the absolute value of the Cash Settlement Amount divided by the Average Unwind 10b-18 VWAP, with the number of Shares rounded up in the event such calculation results in a fractional number of Shares. If, on any Settlement Date, the Shares to be delivered by Party B or Party A hereunder upon Net Share Settlement are not so delivered (the “Net Share Deferred Shares”), and a Forward Price Reduction Date occurs during the period from, and including, such Settlement Date to, but excluding, the date such Shares are actually delivered to such party, then the portion of the Net Share Settlement Shares deliverable by Party A or Party B in respect of the Net Share Deferred Shares shall be adjusted by the Calculation Agent to reflect the occurrence of such Forward Price Reduction Amount for such Forward Price Reduction Date.
10b-18 VWAP:	For any Exchange Business Day during the Unwind Period that is not a Suspension Day, the volume-weighted average price at which the Shares trade as reported in the composite transactions for the Exchange on such Exchange Business Day, excluding (i) trades that do not settle regular way, (ii) opening (regular way) reported trades on the Exchange on such Exchange Business Day, (iii) trades that occur in the last ten minutes before the scheduled close of trading on the Exchange on such Exchange Business Day and ten minutes before the scheduled close of the primary trading session in the market where the trade is effected, and (iv) trades on such Exchange Business Day that do not satisfy the requirements of Rule 10b-18(b)(3), as determined in good faith by the Calculation Agent.

Settlement Currency:	USD.
Failure to Deliver:	Inapplicable.

Representations and Agreements of Party A and Party B:

Each of Party A and Party B represents, warrants and covenants that it:

(a) (i) has such knowledge and experience in financial and business affairs as to be capable of evaluating the merits and risks of entering into the Transaction; (ii) has consulted with its own legal, financial, accounting and tax advisors in connection with the Transaction; and (iii) is entering into the Transaction for a bona fide business purpose;

Additional Representations, Warranties and Agreements of Party B:

Party B hereby represents and warrants to, and agrees with, Party A as of the date hereof that:

(a) Any Shares, when issued and delivered in accordance with the terms of the Transaction, will be duly authorized and validly issued, fully paid and nonassessable, and the issuance thereof will not be subject to any preemptive or similar rights.

(b) Party B has reserved and will keep available at all times, free from preemptive rights, out of its authorized but unissued Shares, solely for the purpose of issuance upon settlement of the Transaction as herein provided, the full number of Shares as shall be issuable at such time upon settlement of the Transaction. All Shares so issuable shall, upon such issuance, be accepted for listing or quotation on the Exchange.

(c) Party B agrees to provide Party A with at least three days’ written notice (an “Issuer Repurchase Notice”) prior to executing any repurchase of Shares by Party B or any of its subsidiaries (or entering into any contract that would require, or give the option to, Party B or any of its subsidiaries, to purchase or repurchase Shares), whether out of profits or capital or whether the consideration for such repurchase is cash, securities or otherwise (an “Issuer Repurchase”), that alone or in the aggregate would result in the Base Amount Percentage (as defined below) being either (i) equal to or greater than 9.0% of the outstanding Shares or (ii) greater by 0.5% or more than the Base Amount Percentage at the time of the immediately preceding Issuer Repurchase Notice (or in the case of the first such Issuer Repurchase Notice, greater than the Base Amount Percentage as of the later of the date hereof or the immediately preceding Settlement Date, if any). The “Base Amount Percentage” as of any day is the fraction (1) the numerator of which is the sum of (i) the Base Amount, and (ii) the “Base Amount,” as such term is defined in the confirmation dated as of August 4, 2025 between Party A and Party B relating to a substantially identical forward transaction with respect to 2,347,418 Shares (the “Base Confirmation”) and (2) the denominator of which is the number of Shares outstanding on such day.

(d) No filing with, or approval, authorization, consent, license, registration, qualification, order or decree of, any court or governmental authority or agency, domestic or foreign, is necessary or required for the execution, delivery and performance by Party B of this Confirmation and the consummation of the Transaction (including, without limitation, the issuance and delivery of Shares on any Settlement Date) except (i) such as have been obtained under the Securities Act of 1933, as amended (the “Securities Act”), and (ii) as may be required to be obtained under state securities laws.

(e) Party B agrees not to make any Issuer Repurchase if, immediately following such Issuer Repurchase, the Base Amount Percentage would be equal to or greater than 9.0%.

(f) Party B is not insolvent, nor will Party B be rendered insolvent as a result of the Transaction.

9

(g) Neither Party B nor any of its Affiliates shall take or refrain from taking any action (including, without limitation, any direct purchases by Party B or any of its Affiliates or any purchases by a party to a derivative transaction with Party B or any of its Affiliates), either under this Confirmation, under an agreement with another party or otherwise, that Party B reasonably believes would cause any purchases of Shares by Party A or any of its Affiliates in connection with any Cash Settlement or Net Share Settlement of the Transaction not to meet the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act if such purchases were made by Party B.

(h) Party B will not engage in any “distribution” (as defined in Regulation M under the Exchange Act (“Regulation M”)) that would cause a “restricted period” (as defined in Regulation M) to occur during any Unwind Period.

(i) Party B is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended).

(j) In addition to any other requirements set forth herein, Party B agrees not to elect Cash Settlement or Net Share Settlement if, in the reasonable judgment of either Party A or Party B, such settlement or Party A’s related market activity would result in a violation of the U.S. federal securities laws or any other federal or state law or regulation applicable to Party B.

(k) Party B (i) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (ii) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (iii) has total assets of at least USD 50 million as of the date hereof.

(l) Party B acknowledges and agrees that:

(i) during the term of the Transaction, Party A and its Affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to establish, adjust or unwind its hedge position with respect to the Transaction;

(ii) Party A and its Affiliates may also be active in the market for the Shares and Share-linked transactions other than in connection with hedging activities in relation to the Transaction;

(iii) Party A shall make its own determination as to whether, when or in what manner any hedging or market activities in Party B’s securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Forward Price and the 10b-18 VWAP;

(iv) any market activities of Party A and its Affiliates with respect to the Shares may affect the market price and volatility of the Shares, as well as the Forward Price and 10b-18 VWAP, each in a manner that may be adverse to Party B; and

(v) the Transaction is a derivatives transaction in which it has granted Party A the right, under certain circumstances, to receive cash or Shares, as the case may be; Party A may purchase Shares for its own account at an average price that may be greater than, or less than, the effective price paid by Party B under the terms of the Transaction.

(m) Party B will notify Party A within five Exchange Business Days of obtaining knowledge of the occurrence of any event that would constitute a Potential Adjustment Event (or, if earlier, the date on which it publicly discloses such Potential Adjustment Event).

10

Covenant of Party B:

Subject to the provisions of “Private Placement Procedures” below, the parties acknowledge and agree that any Shares delivered by Party B to Party A on any Settlement Date will be newly issued Shares and when delivered by Party A (or an Affiliate of Party A) to securities lenders from whom Party A (or an Affiliate of Party A) borrowed Shares in connection with hedging its exposure to the Transaction will be freely saleable without further registration or other restrictions under the Securities Act, in the hands of those securities lenders (provided that such Shares may be subject to restrictions if the status of any such securities lender would cause any such resale restrictions to apply by virtue of such securities lender’s share ownership in Party B, status as an Affiliate of Party B or otherwise), irrespective of whether such stock loan is effected by Party A or an Affiliate of Party A. Accordingly, subject to the provisions of “Private Placement Procedures” below, Party B agrees that the Shares that it delivers to Party A on each Settlement Date will not bear a restrictive legend and that such Shares will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System.

Covenants of Party A:

(a) Unless the provisions set forth below under “Private Placement Procedures” shall be applicable, Party A shall use any Shares delivered by Party B to Party A on any Settlement Date to return Shares to securities lenders to close out open Share loans created by Party A or an Affiliate of Party A in the course of Party A’s or such Affiliate’s hedging activities related to Party A’s exposure under this Confirmation.

(b) In connection with bids and purchases of Shares in connection with any Cash Settlement or Net Share Settlement of the Transaction, Party A shall use its commercially reasonable efforts to conduct its activities, or cause its Affiliates to conduct their activities, in a manner consistent with the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act, as if such provisions were applicable to such purchases.

Insolvency Filing:

Notwithstanding anything to the contrary herein, in the Agreement or in the Definitions, upon any Insolvency Filing in respect of the Issuer, the Transaction shall automatically terminate on the date thereof without further liability of either party to this Confirmation to the other party (except for any liability in respect of any breach of representation or covenant by a party under this Confirmation prior to the date of such Insolvency Filing).

The parties hereto agree and acknowledge that (1) at any point prior to any Insolvency Filing in respect of the Issuer, Party B shall have the unilateral right to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading “Settlement Terms”; and (2) the Transaction shall automatically terminate on the date of any Insolvency Filing pursuant to the provisions set forth in the immediately preceding paragraph only if and to the extent that Party B failed to elect Physical Settlement of the Transaction pursuant to the provisions set forth above under the heading Settlement Terms prior to the relevant Insolvency Filing.

Extraordinary Dividends:

If an ex-dividend date for an Extraordinary Dividend occurs on or after the Trade Date and on or prior to the Maturity Date (or, if later, the last date on which Shares are delivered by Party B to Party A in settlement of the Transaction), Party B shall pay an amount, as determined by the Calculation Agent, in cash equal to the product of such Extraordinary Dividend and the Base Amount to Party A on the earlier of (i) the date on which such Extraordinary Dividend is paid by the Issuer to holders of record of the Shares or (ii) the Maturity Date. “Extraordinary Dividend” means the per Share amount of any cash dividend or distribution declared by the Issuer with respect to the Shares that is specified by the board of directors of the Issuer as an “extraordinary” dividend.

11

Acceleration Events:

The following events shall each constitute an “Acceleration Event”:

(a) Stock Borrow Events. In the good faith commercially reasonable judgment of Party A (i) Party A (or its Affiliate) is unable to hedge Party A’s exposure to the Transaction because (A) of the lack of sufficient Shares being made available for Share borrowing by lenders, or (B) Party A (or an Affiliate of Party A) would incur a Stock Loan Fee to hedge its exposure to the Transaction that is greater than a rate of 200 basis points per annum (each, a “Stock Borrow Event”);

(b) Dividends and Other Distributions. On any day occurring after August 5, 2025 Party B declares a distribution, issue or dividend to existing holders of the Shares of (i) any cash dividend (other than an Extraordinary Dividend) to the extent all cash dividends having an ex-dividend date during the period from and including any Forward Price Reduction Date (with August 5, 2025 being a Forward Price Reduction Date for purposes of this clause (b) only) to but excluding the next subsequent Forward Price Reduction Date exceeds, on a per Share basis, the Forward Price Reduction Amount set forth opposite the first date of any such period on Schedule I or (ii) share capital or securities of another issuer acquired or owned (directly or indirectly) by Party B as a result of a spin-off or other similar transaction or (iii) any other type of securities (other than Shares), rights or warrants or other assets, for payment (cash or other consideration) at less than the prevailing market price as reasonably determined by Party A;

(c) ISDA Early Termination Date. Party A has the right to designate an Early Termination Date pursuant to Section 6 of the Agreement;

(d) Other ISDA Events. The announcement of any event that if consummated, would result in an Extraordinary Event or the occurrence of any Change in Law (other than as specified in clause (Y) of the definition thereof) or a Delisting; provided that in case of a Delisting, in addition to the provisions of Section 12.6(a)(iii) of the 2002 Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, the Nasdaq Global Select Market or the Nasdaq Global Market (or their respective successors); and provided further that the definition of “Change in Law” provided in Section 12.9(a)(ii) of the 2002 Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or public announcement of, the formal or informal interpretation”, (ii) replacing the parenthetical beginning after the word “regulation” in the second line thereof the words “(including, for the avoidance of doubt and without limitation, (x) any tax law or (y) adoption, effectiveness or promulgation of new regulations authorized or mandated by existing statute)” and (iii) immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by Party A on the Trade Date”; or

(e) Ownership Event. In the good faith, reasonable judgment of Party A, on any day, the Share Amount for such day exceeds the Post-Effective Limit for such day (if any applies) (an “Ownership Event”).

For purposes of clause (e) above, the “Share Amount” as of any day is the number of Shares that Party A and any of its Affiliates and any person whose ownership position would be aggregated with that of Party A, including any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part (Party A or any such person or group, a “Party A Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Party B that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership of under any Applicable Restriction, as determined by Party A in its reasonable discretion. The “Post-Effective Limit” means (x) the minimum number of Shares that

12

would give rise to reporting or registration obligations (other than any filing under Section 13 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date) or other requirements (including obtaining prior approval from any person or entity) of a Party A Person, or would result in an adverse effect on a Party A Person, under any Applicable Restriction, as determined by Party A in its reasonable discretion (it being understood that reporting obligations under Section 13 or Section 16 of the Exchange Act and the rules and regulations thereunder, in each case, as in effect on the Trade Date, will not be deemed to have an adverse effect), minus (y) 1% of the number of Shares outstanding.

Materially Increased Costs:

Upon the occurrence of any Change in Law specified in clause (Y) of the definition thereof, Party A and Party B agree to negotiate in good faith for at least five Exchange Business Days (the “Amendment Period”) to amend this Confirmation to take account of the resulting “materially increased cost” as such phrase is used in clause (Y) of the definition of “Change in Law.” Such amendment may, if agreed by Party A and Party B, result in a Change in Law to which an Acceleration Event applies. If, after negotiating in good faith during the Amendment Period to so amend this Confirmation, Party A and Party B are unable to agree upon such an amendment, the relevant Change in Law specified in clause (Y) of the definition thereof shall constitute an Acceleration Event, notwithstanding any language in clause (d) under the heading “Acceleration Events” above to the contrary. The Calculation Agent may, in connection with a Termination Settlement following such Acceleration Event, reduce the Forward Price to compensate Party A for any “materially increased costs” incurred during the Amendment Period. Any Change in Law that results in Party A (or an Affiliate of Party A) incurring a Stock Loan Fee to hedge its exposure to the Transaction that is equal to or less than a rate equal to 200 basis points per annum shall not constitute a “materially increased cost” for purposes of clause (Y) of the definition of “Change in Law” (but may, for the avoidance of doubt, result in a reduction to the Forward Price pursuant to the provisions opposite the caption “Additional Adjustment” above).

Termination Settlement:

Upon the occurrence of any Acceleration Event, Party A shall have the right to designate, upon at least one Scheduled Trading Day’s notice, any Scheduled Trading Day following such occurrence to be a Settlement Date hereunder (a “Termination Settlement Date”) to which Physical Settlement shall apply, and to select the number of Settlement Shares relating to such Termination Settlement Date; provided that (i) in the case of an Acceleration Event arising out of an Ownership Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares necessary to reduce the Share Amount to the Post-Effective Limit and (ii) in the case of an Acceleration Event arising out of a Stock Borrow Event, the number of Settlement Shares so designated by Party A shall not exceed the number of Shares as to which such Stock Borrow Event exists. If, upon designation of a Termination Settlement Date by Party A pursuant to the preceding sentence, Party B fails to deliver the Settlement Shares relating to such Termination Settlement Date when due or otherwise fails to perform obligations within its control in respect of the Transaction, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. If an Acceleration Event occurs during an Unwind Period relating to a number of Settlement Shares to which Cash Settlement or Net Share Settlement applies, then on the Termination Settlement Date relating to such Acceleration Event, notwithstanding any election to the contrary by Party B, Cash Settlement or Net Share Settlement shall apply to the portion of the Settlement Shares relating to such Unwind Period as to which Party A has unwound its hedge and Physical Settlement shall apply in respect of (x) the remainder (if any) of such Settlement Shares and (y) the Settlement Shares designated by Party A in respect of such Termination Settlement Date.

Private Placement Procedures:

Notwithstanding anything to the contrary contained in Section 9.11 of the 2002 Definitions, if Party B is unable to comply with the provisions of “Covenant of Party B” above because of a change in law or a change in the policy of the Securities and Exchange Commission or its staff, or Party A otherwise determines that in its reasonable opinion based on the advice of counsel any Settlement Shares to be delivered to Party A by Party B may not be freely returned by Party A or its Affiliates to securities lenders as described under

13

“Covenant of Party B” above, then delivery of any such Settlement Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Party A; provided that Party A may not otherwise determine that the Settlement Shares are Restricted Shares based solely upon Party A or an Affiliate thereof not having borrowed and sold a number of Shares equal to the Base Amount on or before the Effective Date pursuant to the Registration Statement (as defined in the Underwriting Agreement) with delivery of the Prospectus (as defined in the Underwriting Agreement) if there has been no change in law or a change in the policy of the Securities and Exchange Commission or its staff.

Rule 10b5-1:

It is the intent of Party A and Party B that following any election of Cash Settlement or Net Share Settlement by Party B, the purchase of Shares by Party A during any Unwind Period comply with the requirements of Rule 10b5-1(c)(1)(i)(B) of the Exchange Act and that this Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c).

Party B acknowledges that (i) during any Unwind Period Party B does not have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares by Party A (or its agent or Affiliate) in connection with this Confirmation and (ii) Party B is entering into the Agreement and this Confirmation in good faith and not as part of a plan or scheme to evade compliance with federal securities laws including, without limitation, Rule 10b-5 promulgated under the Exchange Act, and Party B has acted and will act in good faith with respect to the foregoing.

Party B hereby agrees with Party A that during any Unwind Period Party B shall not communicate, directly or indirectly, any Material Non-Public Information (as defined herein) to any employee of Party A, other than Mariano Gaut, Saurabh Mehta, Michael Ripp, James Watts, Robert Han, Matthew Chiavaroli or any other designee confirmed in writing by Party A. For purposes of the Transaction, “Material Non-Public Information” means information relating to Party B or the Shares that (a) has not been widely disseminated by wire service, in one or more newspapers of general circulation, by communication from Party B to its shareholders or in a press release, contained in a public filing made by Party B with the Securities and Exchange Commission, or otherwise disseminated in a manner permitted by the rules and regulations of the Securities and Exchange Commission, and (b) a reasonable investor might consider to be of importance in making an investment decision to buy, sell or hold Shares. For the avoidance of doubt and solely by way of illustration, information should be presumed “material” if it relates to such matters as dividend increases or decreases, earnings estimates, changes in previously released earnings estimates, significant expansion or curtailment of operations, a significant increase or decline of orders, significant merger or acquisition proposals or agreements, significant new products or discoveries, extraordinary borrowing, major litigation, liquidity problems, extraordinary management developments, purchase or sale of substantial assets, or other similar information.

Maximum Share Delivery:

Notwithstanding any other provision of this Confirmation, in no event will Party B be required to deliver on any Settlement Date, whether pursuant to Physical Settlement, Net Share Settlement, Termination Settlement or any Private Placement Settlement, more than a number of Shares equal to 150% of the initial Base Amount to Party A, subject to reduction by the amount of any Shares delivered by Party B on any prior Settlement Date.

Transfer and Assignment:

Party A may assign or transfer any of its rights or delegate any of its duties hereunder to any Affiliate of Party A that has at the time of such assignment or transfer the same or better creditworthiness as Party A so long as (a) any guarantee of Party A’s obligations hereunder continues to remain in full force and effect with respect to such assignee or transferee, (b) such assignee or transferee is organized under the laws of the United States or any State thereof; (c) Party B will not be required to pay to such assignee or transferee an amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement greater than the amount in respect of which Party B would have been required to pay Party A in the absence of such assignment or

14

transfer; (d) Party B will not receive a payment from which an amount has been withheld or deducted on account of a Tax under Section 2(d)(i) of the Agreement in excess of that which Party A would have been required to so withhold or deduct in the absence of such assignment or transfer, unless Party A would be required to pay to Party B amounts under Section 2(d)(i)(4) of the Agreement in respect of such Tax; (e) no Event of Default, Potential Event of Default, Termination Event, Additional Adjustment or Acceleration Event will occur as a result of such assignment or transfer; (f) prior to such assignment or transfer, Party A shall have caused such assignee or transferee to make such payee tax representations and to provide such tax representations as may be reasonably requested by Party B to permit Party B to determine that the assignment or transfer complies with the requirements of this paragraph; and (g) such assignment or transfer will not cause a deemed exchange for Party B of the Transaction under Section 1001 of the Code (as defined below). Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Party A to purchase, sell, receive or deliver any Shares or other securities to or from Party B, Party A may designate any of its Affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Party A’s obligations in respect of the Transaction and any such designee may assume such obligations. Party A shall be discharged of its obligations to Party B to the extent of any such performance.

Indemnity:

Party B agrees to indemnify Party A and its Affiliates and their respective directors, officers, agents and controlling parties (Party A and each such Affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, incurred by or asserted against such Indemnified Party arising out of, in connection with, or relating to, any breach of any covenant or representation made by Party B in this Confirmation or the Agreement and will reimburse any Indemnified Party for all reasonable documented expenses (including reasonable documented legal fees and expenses) in connection with the investigation of, preparation for, or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto, but only to the extent that the relevant loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court of competent jurisdiction to have resulted from such breach. Party B will not be liable under this Indemnity paragraph to the extent that any loss, claim, damage, liability or expense is found in a final and nonappealable judgment by a court to have resulted from Party A’s gross negligence, fraud, willful misconduct or breach of this Confirmation or the Agreement.

4. The Agreement is further supplemented by the following provisions:

No Collateral or Setoff:

Notwithstanding Section 6(f) or any other provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Party B hereunder are not secured by any collateral. Obligations under the Transaction shall not be set off against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall be set off against obligations under the Transaction, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (a) separate amounts shall be calculated as set forth in such Section 6(e) with respect to (i) the Transaction and (ii) all other Transactions, and (b) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement.

Party A acknowledges and agrees that this Confirmation is not intended to convey to Party A rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Party B; provided, however, that nothing herein shall limit or shall be deemed to limit Party A’s right to pursue remedies in the event of a breach by Party B of its obligations and agreements with respect to this Confirmation and the Agreement; and provided further, that nothing herein shall limit or shall be deemed to limit Party A’s rights in respect of any transaction other than the Transaction.

Limit on Beneficial Ownership:

Notwithstanding any other provisions hereof, Party A shall not be entitled to take delivery of any Shares deliverable hereunder (whether in connection with the purchase of Shares on any Settlement Date or any Termination Settlement Date, any Private Placement Settlement or otherwise) to the extent (but only to the extent) that, after such receipt of any Shares hereunder, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 9.0%. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would exceed the Post-Effective Limit or (ii) the Section 16 Percentage would exceed 9.0%. If any delivery owed to Party A hereunder is not made, in whole or in part, as a result of this provision, Party B’s obligation to make such delivery shall not be extinguished and Party B shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Party A gives notice to Party B that, after such delivery, and after taking into account any Shares concurrently deliverable to Party A pursuant to the Base Confirmation, (i) the Share Amount would not exceed the Post-Effective Limit and (ii) the Section 16 Percentage would not exceed 9.0%. The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Party A and any of its Affiliates or any other person subject to aggregation with Party A for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Party A is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day.

In addition, notwithstanding anything herein to the contrary, if any delivery owed to Party A hereunder is not made, in whole or in part, as a result of the immediately preceding paragraph, Party A shall be permitted to make any payment due in respect of such Shares to Party B in two or more tranches that correspond in amount to the number of Shares delivered by Party B to Party A pursuant to the immediately preceding paragraph.

Wall Street Transparency and Accountability Act:

In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (the “WSTAA”), the parties hereby agree that neither the enactment of the WSTAA or any regulation under the WSTAA, nor any requirement under the WSTAA or an amendment made by the WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from any Acceleration Event or Illegality (as defined in the Agreement)).

Acknowledgements:

The parties hereto intend for:

(a) the Transaction to be a “securities contract” as defined in Section 741(7) of Title 11 of the United States Code (the “Bankruptcy Code”), qualifying for the protections under Section 555 of the Bankruptcy Code;

17

(b) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as defined in the Bankruptcy Code;

(c) Party A to be a “financial institution” within the meaning of Section 101(22) of the Bankruptcy Code; and

If Party A is a bank regulated by the Federal Deposit Insurance Corporation, (i) Party A recognizes and intends that the Transaction is, and shall constitute, a “qualified financial contract” as that term is defined in 12 U.S.C. §1821(e)(8)(D)(i), as the same may be amended, modified, or supplemented from time to time; and (ii) Party A represents and warrants that it is authorized by appropriate corporate action under applicable law to enter into the Transaction as evidenced by the execution hereof by an officer of Party A at the level of vice president or higher.

Severability:

If any term, provision, covenant or condition of this Confirmation, or the application thereof to any party or circumstance, shall be held to be invalid or unenforceable in whole or in part for any reason, the remaining terms, provisions, covenants, and conditions hereof shall continue in full force and effect as if this Confirmation had been executed with the invalid or unenforceable provision eliminated, so long as this Confirmation as so modified continues to express, without material change, the original intentions of the parties as to the subject matter of this Confirmation and the deletion of such portion of this Confirmation will not substantially impair the respective benefits or expectations of parties to the Agreement; provided, however, that this severability provision shall not be applicable if any provision of Section 2, 5, 6 or 13 of the Agreement (or any definition or provision in Section 14 to the extent that it relates to, or is used in or in connection with any such Section) shall be so held to be invalid or unenforceable.

Tax Matters:

(a) For the purpose of Section 3(e) of the Agreement, each of Party A and Party B makes the following representation: It is not required by any applicable law, as modified by the practice of any relevant governmental revenue authority, of any Relevant Jurisdiction to make any deduction or withholding for or on account of any Tax from any payment (other than interest under Section 9(h) of the Agreement and any other payments of interest) to be made by it to the other party under the Agreement. In making this representation, it may rely on (i) the accuracy of any representations made by the other party pursuant to Section 3(f) of the Agreement; (ii) the satisfaction of the agreement contained in Section 4(a)(i) or 4(a)(iii) of the Agreement and the accuracy and effectiveness of any document provided by the other party pursuant to Section 4(a)(i) or 4(a)(iii) of the Agreement; and (iii) the satisfaction of the agreement of the other party contained in Section 4(d) of the Agreement; provided that it shall not be a breach of this representation where reliance is placed on clause (ii) of this paragraph and the other party does not deliver a form or document under Section 4(a)(iii) of the Agreement by reason of material prejudice to its legal or commercial position.

(b) For the purpose of Section 3(f) of the Agreement:

(d) Withholding Tax imposed on payments to non-US counterparties under the United States Foreign Account Tax Compliance Act. “Tax” as used in subsection (a) of “Tax Matters” in this Confirmation and “Indemnifiable Tax”, as defined in Section 14 of the Agreement, shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (a “FATCA Withholding Tax”).

Delivery of Cash:

For the avoidance of doubt, nothing in this Confirmation shall be interpreted as requiring Party B to deliver cash in respect of the settlement of the Transaction, except in circumstances where the required cash settlement thereof is permitted for classification of the contract as equity by ASC 815-40-25 (formerly EITF 00-19) as in effect on the Trade Date (including, without limitation, where Party B so elects to deliver cash or fails timely to elect to deliver Shares in respect of such settlement). For the avoidance of doubt, the preceding sentence shall not be construed as limiting (i) the Private Placement Procedures set forth in Annex A hereto, (ii) the payment of cash pursuant to the provisions set forth in Section 3 under the heading “Extraordinary Dividends” or (iii) any damages that may be payable by Party B as a result of breach of this Confirmation.

Party A and Party B agree that if Party B designates a Settlement Date with respect to any of the Other Forwards and for which Cash Settlement or Net Share Settlement is applicable, and the resulting “Unwind Period” for any such Other Forward coincides for any period of time with an Unwind Period for the Transaction (the “Overlap Unwind Period”), Party B shall give written notice to Party A prior to the commencement of such Overlap Unwind Period (which written notice shall indicate whether the relevant Overlap Unwind Period coincides with an “Unwind Period” under Other Forwards with one or both of the Other Forward Counterparties), and Party A shall only be permitted to purchase Shares to unwind its hedge in respect of the Transaction on, and the resulting Unwind Period shall include only, every second Exchange Business Day that is not a Suspension Day during such Overlap Unwind Period (in the case of an Overlap Unwind Period that coincides with an “Unwind Period” under one or more Other Forwards with one (but only one) of the Other Forward Counterparties), or every third Exchange Business Day that is not a Suspension Day during such Overlap Unwind Period (in the case of an Overlap Unwind Period that coincides with “Unwind Periods” under two or more Other Forwards with both of the Other Forward Counterparties), in each case, as notified by Party B, commencing on the first, second or third Exchange Business Day of such Overlap Unwind Period, as notified by Party B (each such Exchange Business Day on which Party A shall be permitted to purchase Shares in accordance with this paragraph, an “Overlap Observation Day”). For the avoidance of doubt, the operation of this “Other Forwards” provision shall not be deemed to give rise to a Disrupted Day or other adjustment to the Transaction.

Mizuho Bank, Ltd. (“Parent”), a banking corporation organized and existing under the laws of Japan, shall fully and unconditionally guarantee all obligations of Party A under this Confirmation and shall execute a guarantee in favor of Party B in a form previously provided to Party B and consistent with parent guarantees customarily provided in respect of Party A’s obligations no later than the fifth Exchange Business Day following the Trade Date.

Agent is so acting solely in its capacity as agent for Party B and Party A pursuant to instructions from Party B and Party A. Each of Party A and Party B agrees to proceed solely against the other to collect or recover any securities or monies owing to it in connection with or as a result of the Transaction.

20

5. Regulatory Provisions:

U.S. Resolution Stay Protocol:

The parties agree that (i) to the extent that prior to the date hereof both parties have adhered to the 2018 ISDA U.S. Resolution Stay Protocol (the “Protocol”), the terms of the Protocol are incorporated into and form a part of the Agreement, and for such purposes the Agreement shall be deemed a Protocol Covered Agreement and each party shall be deemed to have the same status as Regulated Entity and/or Adhering Party as applicable to it under the Protocol; (ii) to the extent that prior to the date hereof the parties have executed a separate agreement the effect of which is to amend the qualified financial contracts between them to conform with the requirements of the QFC Stay Rules (the “Bilateral Agreement”), the terms of the Bilateral Agreement are incorporated into and form a part of the Agreement and each party shall be deemed to have the status of “Covered Entity” or “Counterparty Entity” (or other similar term) as applicable to it under the Bilateral Agreement; or (iii) if clause (i) and clause (ii) do not apply, the terms of Section 1 and Section 2 and the related defined terms (together, the “Bilateral Terms”) of the form of bilateral template entitled “Full-Length Omnibus (for use between U.S. G-SIBs and Corporate Groups)” published by ISDA on November 2, 2018 (currently available on the 2018 ISDA U.S. Resolution Stay Protocol page at www.isda.org and, a copy of which is available upon request), the effect of which is to amend the qualified financial contracts between the parties thereto to conform with the requirements of the QFC Stay Rules, are hereby incorporated into and form a part of the Agreement, and for such purposes the Agreement shall be deemed a “Covered Agreement,” Party A shall be deemed a “Covered Entity” and Party B shall be deemed a “Counterparty Entity.” In the event that, after the date of the Agreement, both parties hereto become adhering parties to the Protocol, the terms of the Protocol will replace the terms of this paragraph. In the event of any inconsistencies between the Agreement and the terms of the Protocol, the Bilateral Agreement or the Bilateral Terms (each, the “QFC Stay Terms”), as applicable, the QFC Stay Terms will govern. Terms used in this paragraph without definition shall have the meanings assigned to them under the QFC Stay Rules. For purposes of this paragraph, references to “the Agreement” include any related credit enhancements entered into between the parties or provided by one to the other. In addition, the parties agree that the terms of this paragraph shall be incorporated into any related covered affiliate credit enhancements, with all references to Party A replaced by references to the covered affiliate support provider.

“QFC Stay Rules” means the regulations codified at 12 C.F.R. 252.2, 252.81–8, 12 C.F.R. 382.1-7 and 12 C.F.R. 47.1-8, which, subject to limited exceptions, require an express recognition of the stay-and-transfer powers of the FDIC under the Federal Deposit Insurance Act and the Orderly Liquidation Authority under Title II of the Dodd Frank Wall Street Reform and Consumer Protection Act and the override of default rights related directly or indirectly to the entry of an affiliate into certain insolvency proceedings and any restrictions on the transfer of any covered affiliate credit enhancements.

ANNEX A

PRIVATE PLACEMENT PROCEDURES

(i) If Party B delivers the Restricted Shares pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Party B shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Party A; provided that if, on or before the date that a Private Placement Settlement would occur, Party B has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(a)(2) of the Securities Act for the sale by Party B to Party A (or any Affiliate designated by Party A) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Party A (or any such Affiliate of Party A) or Party B fails to deliver the Restricted Shares when due or otherwise fails to perform obligations within its control in respect of a Private Placement Settlement, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Party A, due diligence rights (for Party A or any designated buyer of the Restricted Shares by Party A), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Party A. In the case of a Private Placement Settlement, Party A shall, in its good faith discretion, adjust the number of Restricted Shares to be delivered to Party A hereunder in a commercially reasonable manner to reflect the fact that such Restricted Shares may not be freely returned to securities lenders by Party A and may only be saleable by Party A at a discount to reflect the lack of liquidity in Restricted Shares based on actual charges or discounts given. Notwithstanding the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Clearance System Business Day following notice by Party A to Party B of the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Settlement Date or Termination Settlement Date that would otherwise be applicable.

(ii) If Party B delivers any Restricted Shares in respect of the Transaction, Party B agrees that (i) such Shares may be transferred by and among Party A and its Affiliates and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after the applicable Settlement Date, Party B shall promptly remove, or cause the transfer agent for the Shares to remove, any legends referring to any transfer restrictions from such Shares upon delivery by Party A (or such Affiliate of Party A) to Party B or such transfer agent of seller’s and broker’s representation letters customarily delivered by Party A or its Affiliates in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, each without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Party A (or such Affiliate of Party A).
