Item 1.01.

Entry into a Material Definitive Agreement.

On August 4, 2026, Pinnacle West Capital

Corporation (the “Company”) entered into an Equity Distribution Agreement (the “Equity Distribution Agreement”)

with BMO Capital Markets Corp., BTIG, LLC, Citigroup Global Markets Inc., Morgan Stanley & Co. LLC, RBC Capital Markets, LLC,

Scotia Capital (USA) Inc., TD Securities (USA) LLC and Truist Securities, Inc., as managers (each, a “Manager” and, collectively,

the “Managers”), Bank of Montreal, Citibank, N.A., Morgan Stanley & Co. LLC, Nomura Global Financial Products, Inc.,

Royal Bank of Canada, The Bank of Nova Scotia, The Toronto-Dominion Bank and Truist Bank or one or more of their respective affiliates,

as forward purchasers (in such capacity, each, a “Forward Purchaser” and, collectively, the “Forward Purchasers”),

and BMO Capital Markets Corp., Citigroup Global Markets Inc., Morgan Stanley & Co. LLC, Nomura Securities International, Inc.

(acting through BTIG, LLC as agent), RBC Capital Markets, LLC, Scotia Capital (USA) Inc., TD Securities (USA) LLC and Truist Securities, Inc.,

as forward sellers (in such capacity, each, a “Forward Seller” and, collectively, the “Forward Sellers”), relating

to the offer and sale from time to time of shares of the Company’s common stock, no par value, having an aggregate gross sales price

of up to $500,000,000 (the “Shares”).

Sales of the Shares made under the Equity Distribution

Agreement, if any, may be made by any method permitted by applicable law and deemed to be an “at the market offering” as defined

in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including by means of ordinary brokers’

transactions through the facilities of the New York Stock Exchange or through a market maker or directly on or through an electronic communications

network, at market prices prevailing at the time of sale or at prices related to prevailing market prices. In addition, the Shares may

be offered and sold by such other methods, including privately negotiated transactions (including block transactions), as the Company

and the Managers or the Forward Sellers agree to in writing. The Company may also sell Shares to one or more of the Managers, as principal

for their own accounts, at a price to be agreed upon at the time of sale. Each Manager will receive from the Company a commission of up

to 1% of the gross sales price per share for any Shares sold by it under the Equity Distribution Agreement.

The Equity Distribution Agreement provides that,

in addition to the issuance and sale of Shares by the Company to or through the Managers, the Company may also enter into one or more

forward sale agreements pursuant to master forward confirmations entered into between the Company and the relevant Forward Purchaser,

a form of which is attached to the Equity Distribution Agreement as Exhibit C thereto (each, a “Master Forward Confirmation”),

and related supplemental confirmations to be entered into between the Company and the relevant Forward Purchaser pursuant thereto (collectively,

a “Forward Sale Agreement”). In connection with any Forward Sale Agreement, the relevant Forward Purchaser will borrow from

third parties and, through its affiliated Forward Seller, or in the case of Nomura Securities International, Inc., through its agent,

BTIG, LLC, sell a number of Shares equal to the number of Shares underlying the particular Forward Sale Agreement. In connection with

any Forward Sale Agreement, the relevant Forward Seller will receive, in the form of a reduced initial forward sale price under the related

Forward Sale Agreement, a commission of up to 1% of the gross sales prices of all borrowed shares of the Company’s common stock

sold during the applicable forward hedge selling period by it as Forward Seller (which commission, in the case of Nomura Securities International, Inc.,

may be shared with its agent, BTIG, LLC).

In no event will the aggregate number of Shares

sold through the Managers or the Forward Sellers under the Equity Distribution Agreement and under any Forward Sale Agreement have an

aggregate gross sales price in excess of $500,000,000. The Company has no obligation to offer or sell any Shares under the Equity Distribution

Agreement and may at any time suspend offers and sales under the Equity Distribution Agreement. The offer and sale of Shares pursuant

to the Equity Distribution Agreement will terminate upon the earlier of (1) the sale of all Shares subject to the Equity Distribution

Agreement or (2) the termination of the Equity Distribution Agreement by the Company or by the Managers, the Forward Purchasers and

the Forward Sellers.

The net proceeds that the Company receives from

the sales of Shares under the Equity Distribution Agreement from the Managers will be the gross proceeds received from such sales less

the commissions and less any other costs the Company may incur in issuing and/or selling Shares. The Managers and the Forward Sellers

are not required to sell any specific number or dollar amount of the Shares. Subject to the terms and conditions of the Equity Distribution

Agreement, each of the Managers and the Forward Sellers will use commercially reasonable efforts to sell on the Company’s behalf

any Shares as instructed by the Company. The Company will not initially receive any proceeds from the sale of borrowed shares of its common

stock by the Forward Sellers. The Company expects to fully physically settle each particular Forward Sale Agreement (by delivery of Shares)

with the relevant Forward Purchaser on one or more dates specified by the Company on or prior to the maturity date of that particular

Forward Sale Agreement, in which case the Company will expect to receive aggregate net cash proceeds at settlement equal to the number

of Shares underlying the particular Forward Sale Agreement multiplied by the relevant forward sale price. The forward sale price that

the Company expects to receive upon physical settlement of a particular Forward Sale Agreement will be subject to adjustment on a daily

basis based on a floating interest rate factor equal to the overnight bank rate less a spread and will be decreased based on amounts related

to expected dividends on shares of its common stock during the term of the particular Forward Sale Agreement. If the Company elects to

cash settle or net share settle a Forward Sale Agreement, it may not (in the case of cash settlement) or will not (in the case of net

share settlement) receive any proceeds, and the Company may owe cash (in the case of cash settlement) or Shares (in the case of net share

settlement) to the relevant Forward Purchaser.

The Equity Distribution Agreement contains customary

representations and warranties of the parties and indemnification and contribution provisions under which the Company and the Managers,

the Forward Purchasers and the Forward Sellers have agreed to indemnify each other against certain liabilities, including liabilities

under the Securities Act. The Company intends to use the net proceeds from any sale of the Shares, after deducting the Managers’

commission and the Company’s offering expenses, and the net proceeds payable upon settlement of any Forward Sale Agreement, in each

case, for investment in Arizona Public Service Company (“APS”) to fund capital expenditures, for the repayment of all or a

portion of the Company’s or APS’s commercial paper outstanding from time to time and for general corporate purposes.

The offer and sale of the Shares have been registered

under the Securities Act pursuant to a Registration Statement on Form S-3 (Registration No. 333-277448) of the Company, as supplemented

by the Prospectus Supplement dated August 4, 2026 relating to the Shares.

The summary of the Equity Distribution Agreement

set forth in this Item 1.01 does not purport to be complete and is qualified by reference to such agreement, including the form of Master

Forward Confirmation attached as Exhibit C thereto, which is filed as Exhibit 1.1 hereto and is incorporated herein by reference.

Number of Shares” (which shall be determined as provided in the Master Forward Confirmation) and the “Notice Settlement Number”

(which shall be the number set forth opposite the term “Notice Settlement Number” in the Forward Placement Notice).

(v)             For

each Forward, the Company shall be obligated to enter into a Forward Contract with the Forward Purchaser, and the Forward Purchaser shall

be obligated to use commercially reasonable efforts to borrow, and the Forward Seller shall use commercially reasonable efforts consistent

with its normal trading and sales practices to sell, the Forward Hedge Shares pursuant to such Forward only if and when the Company delivers

a Forward Placement Notice to the Forward Purchaser and the Forward Seller and the Forward Purchaser and the Forward Seller have accepted

such Forward Placement Notice as provided in Section 2(b)(ii). The Company shall have the right, in its sole discretion, to request

that the Forward Seller and Forward Purchaser amend at any time and from time to time any Forward Placement Notice, and if such amendment

is accepted by the Forward Purchaser and the Forward Seller, each of the Forward Purchaser and the Forward Seller shall, as soon as reasonably

practicable after receiving notice of such amendment, modify its offers to sell or borrow, as applicable, consistent with any such amendment

notice; provided, however, that (i) the Company may not amend the Forward Hedge Amount if such amended Forward Hedge

Amount would be less than the Actual Sold Forward Amount as of the date of such amendment and (ii) the Company shall not have the

right to amend a Forward Placement Notice after the related Supplemental Confirmation has been delivered to the Company.

(vi)             Each

of the Company, the Forward Purchasers and the Forward Sellers acknowledge and agree that: (x) there can be no assurance that the

Forward Purchaser will be successful in borrowing or that the Forward Seller will be successful in selling Forward Hedge Shares; (y) a

Forward Seller will incur no liability or obligation to the Company, the Forward Purchaser or any other person if it does not sell Forward

Hedge Shares borrowed by the Forward Purchaser for any reason other than a failure by the Forward Seller to use commercially reasonable

efforts consistent with its normal trading and sales practices to sell such Forward Hedge Shares as required under this Section 2(b);

and (z) the Forward Purchaser will incur no liability or obligation to the Company, the Forward Seller or any other person if it

does not borrow Forward Hedge Shares for any reason other than a failure by the Forward Purchaser to use commercially reasonable efforts

to borrow such Forward Hedge Shares as required under this Section 2(b). Notwithstanding anything herein to the contrary, a Forward

Purchaser’s obligation to use commercially reasonable efforts to borrow or cause its affiliate to borrow all or any portion of

the Forward Hedge Shares (and a Forward Seller’s obligation to use commercially reasonable efforts consistent with its normal trading

and sales practices to sell such portion of the Forward Hedge Shares) for any Forward hereunder shall be subject in all respects to clause

(ii) of the provisions under the caption “Conditions to Effectiveness” in Section 3 of the Master Forward Confirmation.

In acting hereunder, any Forward Seller will be acting as agent for the Forward Purchaser and not as principal.

Company shall not authorize the issuance and sale of, and such Manager shall not sell, any Issuance Shares, and such Forward Seller shall

not sell any Forward Hedge Shares, in each case at a price lower than the minimum price therefor designated by the Company pursuant to

Section 2(a) or in a number in excess of the number of Shares approved for listing on the Exchange, or in excess of the number

or amount of Shares available for issuance on the Registration Statement for which the applicable registration fee has been paid, it

being understood and agreed by the parties hereto that compliance with any such limitations regarding the number of Shares shall be the

sole responsibility of the Company. In addition, the Company, on the one hand, or such Manager or Forward Seller, on the other hand,

may, upon notice to the other party hereto by telephone (confirmed promptly by email or facsimile), suspend an offering of the Issuance

Shares or Forward Hedge Shares pursuant to this Agreement; provided, however, that such suspension or termination shall

not affect or impair the parties’ respective obligations with respect to the Issuance Shares or Forward Hedge Shares sold hereunder

prior to the giving of such notice.

(d)             Such

Manager or Forward Seller shall provide written confirmation (which may be by facsimile or email) to the Company following the close

of trading on the Exchange each day on which Shares are sold under this Agreement setting forth (i) the amount of Issuance Shares

or the Actual Sold Forward Amount sold on such day, (ii) the gross offering proceeds received from such sale of the Shares, and

(iii) in the case of the Issuance Shares, the commission payable by the Company to such Manager with respect to such sale of Issuance

Shares.

(e)             At

each Time of Sale, Settlement Date and Representation Date (as defined in Section 6(k)), the Company shall be deemed to have affirmed

each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date (except

to the extent that such representations and warranties speak as of another date, in which case such representations and warranties shall

be true and correct as of such other date) but modified to incorporate the disclosures contained in the Registration Statement and the

Prospectus, in each case as amended or supplemented as of such date. Any obligation of each Manager, Forward Purchaser and Forward Seller

to use commercially reasonable efforts consistent with its normal trading and sales practices to sell the Shares on behalf of the Company

in their respective capacities shall be subject to the continuing accuracy of the representations and warranties of the Company herein,

to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions specified

in Section 5.

(f)             Notwithstanding

any other provision of this Agreement, the Company, the Managers, the Forward Purchasers and the Forward Sellers agree that no sales

of Shares shall take place, the Company shall not request the sales of any Shares that would be sold and the Managers, the Forward Purchasers

and the Forward Sellers shall not be obligated to sell or offer to sell, (i) during any period in which the Company, in its sole

discretion, determines that its insider trading policy, as such policy may be amended from time to time, would prohibit the purchase

or sale of Common Stock by the Company, or during any other period in which the Company is in possession of material non-public information

or (ii) except as provided in Section 2(g), at any time from and including the date (each, an “Announcement Date”)

on which the Company shall issue a press release containing, or shall otherwise publicly announce, its earnings, revenues or other results

of operations (each, an “Earnings Announcement”) through and including the time that the Company files (a “Filing

Time”) a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated financial statements

as of and for the same period or periods, as the case may be, covered by such Earnings Announcement.

(g)             If

the Company wishes to offer Shares at any time during the period from and including an Announcement Date through and including the corresponding

Filing Time, then the Company shall (i) prepare and deliver to the Managers (with a copy to its counsel) a Current Report on Form 8-K

which shall include substantially the same financial and related information as was set forth in the relevant Earnings Announcement (other

than any earnings projections, similar forward-looking data and officers’ quotations) (each, an “Earnings 8-K”),

in form and substance reasonably satisfactory to the Managers, the Forward Purchasers and the Forward Sellers, and obtain the consent

of the Managers, the Forward Purchasers and the Forward Sellers to the filing thereof (such consent not to be unreasonably withheld),

(ii) provide the Managers, the Forward Purchasers and the Forward Sellers with the officer’s certificate, opinions/letters

of the Company’s counsel, opinions/letters of the Managers’ counsel and accountants’ letters called for by Section 6(k),

Section 6(l) and Section 6(o), respectively, (iii) upon request, afford the Managers, the Forward Purchasers and

the Forward Sellers the opportunity to conduct a reasonable due diligence review in accordance with Section 6(r) and (iv) file

such Earnings 8-K with the Commission, after which the provisions of clause (ii) of Section 2(f) shall not be applicable

for the period from and after the time at which the foregoing conditions shall have been satisfied through and including the Filing Time

of the relevant Quarterly Report on Form 10-Q or Annual Report on Form 10-K under the Exchange Act, as the case may be. For

purposes of clarity, the parties hereto agree that (A) the delivery of any officer’s certificate, opinions/letters of counsel

and accountants’ letters pursuant to this Section 2(g) shall not relieve the Company from any of its obligations under

this Agreement with respect to any Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, including,

without limitation, the obligation to deliver officer’s certificates, opinions/letters of counsel and accountants’ letters

as provided in Section 6 and (B) this Section 2(g) shall in no way affect or limit the operation of clause (i) of

Section 2(f), which shall have independent application.

3.             Fee.

(a)             The

compensation to each Manager and Forward Seller for sales of the Shares hereunder shall be equal to up to 1% of the aggregate gross sales

price of the Shares sold by such Manager and Forward Seller pursuant to this Agreement, which commission shall be as set forth in the

applicable Company order or Forward Placement Notice, as applicable.

(b)             Notwithstanding

the foregoing, in the event the Company engages a Manager, Forward Purchaser or Forward Seller for a sale of Shares in a transaction

that would constitute a “distribution”, within the meaning of Rule 100 of Regulation M under the Exchange Act or a “block”

within the meaning of Rule 10b-18(a)(5) under the Exchange Act, the Company will provide the Managers, the Forward Purchasers

and the Forward Sellers, at their request and upon reasonable advance notice to the Company, on or prior to the Settlement Date, the

opinions of counsel, accountants’ letters and officer’s certificates pursuant to Section 6, each dated the Settlement

Date, and such other documents and information as the Managers, the Forward Purchasers or the Forward Sellers shall reasonably request,

and the Company and the Managers, the Forward Purchasers and the Forward Sellers will agree to compensation that is customary for the

Managers, the Forward Purchasers and/or the Forward Sellers, as the case may be, with respect to such transaction.

4.             Payment,

Delivery and Other Obligations.

(a)             Settlement

for sales of the Issuance Shares pursuant to this Agreement will occur on the Trading Day (or such earlier day as is industry practice

for regular-way trading) following the date on which such sales are made (each such day, an “Issuance Shares Settlement Date”).

On each Issuance Shares Settlement Date, the Issuance Shares sold through the relevant Manager for settlement on such date shall be issued

and delivered by the Company to such Manager against payment of the net proceeds from the sale of such Issuance Shares. Settlement for

all such Issuance Shares shall be effected by free delivery of the Issuance Shares by the Company or its transfer agent to such Manager’s

or its designee’s account (provided that such Manager shall have given the Company written notice of such designee prior

to the Issuance Shares Settlement Date) at The Depository Trust Company or by such other means of delivery as may be mutually agreed

upon by the parties hereto, which in all cases shall be freely tradable, transferable, registered shares in good deliverable form, in

return for payment in same day funds delivered to the account designated by the Company.

(b)             Each

sale of Forward Hedge Shares will be settled as between the Forward Purchaser and the Forward Seller on each applicable Forward Hedge

Settlement Date following the relevant Forward Date. On or before each Forward Hedge Settlement Date, the Forward Purchaser will, or

will cause its transfer agent to, electronically transfer the Forward Hedge Shares being offered and sold by crediting the Forward Seller

or its designee’s account at The Depository Trust Company by free delivery or by such other means of delivery as may be mutually

agreed upon by the Forward Purchaser and the Forward Seller and, upon receipt of such Forward Hedge Shares, which in all cases shall

be freely tradeable, transferable, registered shares in good deliverable form, the Forward Seller shall deliver to the Forward Purchaser

the related portion of the Forward Hedge Price in same day funds delivered to an account designated by the Forward Purchaser prior to

the relevant Forward Hedge Settlement Date.

the Company, or its transfer agent (if applicable), shall default on its obligation to deliver the Issuance Shares on any Issuance Shares

Settlement Date, the Company shall (i) hold such Manager harmless against any loss, claim, damage or reasonable and documented expense

(including reasonable and documented legal fees and expenses), as incurred, arising out of or in connection with such default by the

Company and (ii) pay such Manager any commission, discount or other compensation to which it would otherwise be entitled absent

such default.

6.             Covenants

of the Company. The Company covenants with the Managers, the Forward Purchasers and the Forward Sellers as follows:

(a)             Before

making any offer relating to the Shares that would constitute a free writing prospectus or filing any Permitted Free Writing Prospectus,

and before filing any amendment or supplement to the Registration Statement or the Prospectus (other than any report filed under the

Exchange Act or any prospectus supplement relating to the offering of securities other than Common Stock), whether before or after the

time that the Registration Statement becomes effective, the Company will furnish to the Managers, the Forward Purchasers and the Forward

Sellers and their respective counsel a copy of the proposed Permitted Free Writing Prospectus, amendment or supplement for review, and

will not make any offer relating to the Shares that would constitute a free writing prospectus or file any such Permitted Free Writing

Prospectus or file any such proposed amendment or supplement to which any Manager, Forward Purchaser or Forward Seller may reasonably

object. Any such free writing prospectus consented to by the Managers, the Forward Purchasers and the Forward Sellers will be considered

a Permitted Free Writing Prospectus. The Company will file all reports and any definitive proxy or information statements required to

be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act during the Delivery

Period. The Company will furnish copies of the Prospectus and each Permitted Free Writing Prospectus, if any (to the extent not previously

delivered), to the Managers, the Forward Purchasers and the Forward Sellers in New York City prior to 10:00 A.M., New York City time,

within three business days after the date of this Agreement, or as promptly as practicable thereafter with respect to any Permitted Free

Writing Prospectus first used after the date of this Agreement, in such quantities as the Managers, the Forward Purchasers or the Forward

(b)             For

the duration of the Delivery Period, the Company will include in its Quarterly Reports on Form 10-Q, and in its Annual Reports on

Form 10-K, a summary detailing, for the relevant reporting period, (i) the number of Shares sold through the Managers, the

Forward Purchasers and the Forward Sellers pursuant to this Agreement and (ii) the net proceeds received by the Company from such

sales. In the alternative, at the election of the Company, the Company may prepare a prospectus supplement (each, an “Interim

Prospectus Supplement”) with such summary information and, at least once per quarter for the duration of the Delivery Period

and, subject to Section 6(a), file such Interim Prospectus Supplement pursuant to Rule 424(b) under the Securities Act

(and within the time periods required by Rule 424(b) under the Securities Act and Rule 430A, 430B or 430C under the Securities

Act).

Company will file any Permitted Free Writing Prospectus to the extent required by Rule 433 under the Securities Act and provide

copies of the Prospectus, the Prospectus Supplement and each Permitted Free Writing Prospectus, if any (to the extent not previously

delivered or filed on the Commission’s Electronic Data Gathering, Analysis and Retrieval system or any successor system thereto),

to the Managers, the Forward Purchasers and the Forward Sellers via electronic mail in “.pdf” format on such filing date

by the rules or regulations of the Exchange or such other exchange or market.

(d)             During

the Delivery Period, the Company will advise the Managers, the Forward Purchasers and the Forward Sellers promptly, and confirm such

advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective; (ii) when any

supplement to the Prospectus or any amendment to the Prospectus or any Permitted Free Writing Prospectus has been filed; (iii) of

any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the

receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional

information; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing

or suspending the use of the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A

of the Securities Act; (v) of the occurrence of any event within the Delivery Period as a result of which the Prospectus, the General

Disclosure Package or any Permitted Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material

fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light

of the circumstances existing when the Prospectus, the General Disclosure Package or any such Permitted Free Writing Prospectus is delivered

to a purchaser, not misleading; and (vi) of the receipt by the Company of any 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 Securities Act; and

the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration

Statement, preventing or suspending the use of the Prospectus or suspending any such qualification of the Shares and, if any such order

is issued, the Company will use its reasonable best efforts to obtain as soon as possible the withdrawal thereof.

(e)             If,

after the date hereof and during the Delivery Period, either (i) any event shall occur or condition shall exist as a result of which

any of the General Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to

state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made,

not misleading or (ii) it is necessary to amend or supplement the General Disclosure Package to comply with law, the Company will

promptly notify the Managers, the Forward Purchasers and the Forward Sellers thereof and forthwith prepare and, subject to Section 6(c),

file with the Commission (to the extent required) and furnish to the Managers, the Forward Purchasers and the Forward Sellers, such amendments

or supplements to the General Disclosure Package (or any document to be filed with the Commission and incorporated by reference therein)

as may be necessary so that the statements in any of the General Disclosure Package as so amended or supplemented (including such documents

to be incorporated by reference therein) will not, in the light of the circumstances under which they were made, be misleading or so

that any of the General Disclosure Package will comply with law.

(f)             The

Company will qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Managers, the Forward

Purchasers or the Forward Sellers shall reasonably request and will continue such qualifications in effect so long as required for distribution

of the Shares; provided that the Company shall not be required to (i) qualify as a foreign corporation or other entity or

as a dealer in securities in any jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent

to service of process in any jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so

subject.

(g)             The

Company will make generally available to the holders of the Shares and the Managers, the Forward Purchasers and the Forward Sellers as

soon as practicable an earning statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158

under the Securities Act covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring

after the “effective date” (as defined in Rule 158 under the Securities Act) of the Registration Statement.

(h)             The

Company shall pay all expenses incident to the performance of its obligations under this Agreement, whether or not the transactions contemplated

hereby are consummated or this Agreement is terminated, including, without limitation: (i) costs, expenses, fees and taxes in connection

with the preparation and filing of the Registration Statement, the Basic Prospectus, the Prospectus, the Prospectus Supplement, each

Permitted Free Writing Prospectus, if any, and any amendments or supplements thereto, and the printing and furnishing of copies of each

thereof to the Managers, the Forward Purchasers and the Forward Sellers (including costs of mailing and shipment), (ii) costs, expenses,

fees and taxes in connection with the registration, issue, sale and delivery of the Shares including any stock or transfer taxes and

stamp or similar duties payable upon the sale, issuance or delivery of the Shares, (iii) costs, expenses, fees and taxes in connection

with the producing, word processing and/or printing of this Agreement, any Powers of Attorney and any closing documents (including compilations

thereof) and the reproduction and/or printing and furnishing of copies of each thereof to the Managers (including costs of mailing and

shipment), (iv) costs, expenses, fees and taxes in connection with the qualification of the Shares for offering and sale under state

laws and the determination of their eligibility for investment under state or foreign law (including the reasonable legal fees and filing

fees and other disbursements of U.S. or other foreign counsel for the Managers, the Forward Purchasers and the Forward Sellers) and the

printing and furnishing of copies of any blue sky surveys, (v) costs, expenses, fees and taxes in connection with the listing of

the Shares on the Exchange, (vi) costs, expenses, fees and taxes in connection with any filing with, and any review of the public

of any such fees and disbursements pursuant to this clause (vi), and (vii) the fees and disbursements of the Company’s counsel

and the Company’s accountants. Except as set forth in this Section 6 and Section 8, the Managers, the Forward Purchasers

and the Forward Sellers will pay all of their other out-of-pocket costs and expenses incurred in connection with entering into the Transaction

Documents and the transactions contemplated thereby, including, without limitation, any travel and similar expenses, whether or not the

transactions contemplated thereby are consummated or any such Transaction Document is terminated.

(i)             If

the third anniversary of the initial effective date of the Registration Statement occurs before all the Shares have been sold and this

Agreement remains in full force and effect, prior to such third anniversary, the Company will file, subject to Section 6(a), a new

shelf registration statement and will take any other action necessary to permit the public offering of the Shares to continue without

interruption (whereupon references herein to the Registration Statement shall include such new registration statement declared effective

by the Commission).

(j)             The

Company will use its commercially reasonable efforts to cause the Shares to be listed for trading on the Exchange and to maintain such

listing.

(k)             Upon

commencement of the offering of the Shares under this Agreement (and upon the recommencement of the offering of the Shares under this

Agreement following the termination of a suspension of sales hereunder), and each time that (i) the Registration Statement or the

Prospectus is amended or supplemented (other than a prospectus supplement relating solely to the offering of Shelf Securities other than

the Shares) or (ii) there is filed with the Commission any document incorporated by reference into the Prospectus (other than a

Current Report on Form 8-K or definitive proxy statement) (such commencement date (and any such recommencement date, if applicable)

and each such date referred to in clauses (i) and (ii) above, a “Representation Date”), the Company will

furnish or cause to be furnished to the Managers, the Forward Purchasers and the Forward Sellers forthwith a certificate dated and delivered

as of such date, in form reasonably satisfactory to the Managers, the Forward Purchasers and the Forward Sellers, to the effect that

the statements contained in the certificate referred to in Section 5(b) are true and correct at the time of such commencement,

recommencement, amendment, supplement or filing, as the case may be, as though made at and as of such time modified as necessary to relate

to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such certificate.

(l)             On

each Representation Date, the Company will cause to be furnished to the Managers, the Forward Purchasers and the Forward Sellers, dated

as of such date, in form and substance reasonably satisfactory to the Managers, the Forward Purchasers and the Forward Sellers, the letters

described in Section 5(c) and Section 5(d), modified as necessary to relate to the Registration Statement and the Prospectus

as amended and supplemented to the time of delivery of such letters.

(m)             If

the Company has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange

Act are not satisfied with respect to the Company or the Common Stock, it shall promptly notify the Managers, the Forward Purchasers

and the Forward Sellers, and sales of the Shares under this Agreement shall be suspended until that or other exemptive provisions have

been satisfied in the commercially reasonable judgment of each party.

(n)             The

Company agrees that any offer to sell, any solicitation of an offer to buy, or any sales of Shares by the Company pursuant to this Agreement

shall be effected only by or through one Manager, Forward Purchaser or Forward Seller on any business day.

(o)             Upon

commencement of the offering of the Shares under this Agreement (and upon the recommencement of the offering of the Shares under this

Agreement following the termination of a suspension of sales hereunder) and each time that (i) the Registration Statement or the

Prospectus is amended or supplemented to include additional financial information, (ii) the Company files an Annual Report on Form 10-K

or Quarterly Report on Form 10-Q, (iii) the Company files an Earnings 8-K, (iv) there is filed with the Commission any

document (other than an Annual Report on Form 10-K or Quarterly Report on Form 10-Q) incorporated by reference into the Prospectus

which contains additional or amended financial information or (v) on such other dates as may be reasonably requested by the Managers,

the Forward Purchasers or the Forward Sellers, Deloitte & Touche LLP, or other independent accountants, shall deliver to the

Managers, the Forward Purchasers and the Forward Sellers the comfort letter described in Section 5(e), as applicable.

(p)             The

obligations of any party contained in Section 6(k), Section 6(l) and Section 6(o) may be satisfied by delivery

on an alternative date, in which case the certificates, opinions and letters required pursuant to such sections may be dated as of such

alternative date; provided that such alternative date shall be mutually agreed upon by the Company and the Managers, the Forward

Purchasers and the Forward Sellers, if applicable.

(q)             The

obligation to deliver or cause to be delivered the documents referred to in Section 6(k), Section 6(l) and Section 6(o) shall

be waived for any Representation Date occurring at a time at which no instruction by the Company to any Manager to sell Shares under

this Agreement is in effect, which waiver shall continue until the earlier to occur of the date the Company delivers an instruction to

any Manager to sell Shares pursuant to Section 2(a) (which for such calendar quarter shall be considered a Representation Date)

and the next occurring Representation Date for which no such waiver is made; provided, however, that the Company may elect,

in its sole discretion, to deliver or cause to be delivered the documents referred to in Section 6(k), Section 6(l) and

Section 6(o) and thereby satisfy its obligations hereunder, notwithstanding the fact that no instruction by the Company to

the Managers to sell Shares under this Agreement is in effect. Notwithstanding the foregoing, if the Company subsequently decides to

sell Shares following a Representation Date when the Company relied on such waiver and did not deliver or cause to be delivered the documents

referred to in Section 6(k), Section 6(l) and Section 6(o), then before the Company delivers an instruction pursuant

to Section 2(a) or any Manager sells any Shares, the Company shall deliver or cause to be delivered documents of the same tenor

as those referred to in Section 5(b), Section 5(c), Section 5(d) and Section 5(e).

(r)             The

Company will comply with the Due Diligence Protocol attached hereto on Schedule III and any other due diligence review or call

reasonably requested by any Manager, Forward Purchaser or Forward Seller.

(s)             The

Company will reserve and keep available at all times, free of preemptive rights, shares of Common Stock for the purpose of enabling the

Company to satisfy its obligations hereunder.

(t)             The

Company consents to the Managers, the Forward Purchasers and the Forward Sellers trading in the Common Stock for each Manager’s,

each Forward Purchaser’s and each Forward Seller’s own accounts, respectively, and for the account of their respective clients

at the same time as sales of the Shares occur pursuant to this Agreement.

(u)             The

Company agrees that each acceptance by the Company of an offer to purchase the Shares hereunder shall be deemed to be an affirmation

to the Managers, the Forward Purchasers and the Forward Sellers that the representations and warranties of the Company contained in or

made pursuant to this Agreement are true and correct as of the date of such acceptance as though made at and as of such date, and an

undertaking that such representations and warranties will be true and correct as of the Time of Sale and the Settlement Date for the

Shares relating to such acceptance as though made at and as of each of such dates (except (i) that such representations and warranties

shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented relating to such Shares and (ii) to

the extent that such representations and warranties speak as of another date, in which case such representations and warranties shall

be true and correct as of such other date).

(v)             At

any time that sales of the Shares have been made but not settled, or the Company has outstanding with a Manager any instructions to sell

the Shares but such instructions have not been fulfilled or cancelled or has outstanding with a Forward Purchaser and a Forward Seller

any Forward Placement Notice with respect to which a Forward Hedge Selling Period is continuing, without (a) giving such Manager,

Forward Purchaser or Forward Seller at least two (2) business days’ prior written notice specifying the nature of the proposed

sale and the date of such proposed sale and (b) such Manager, Forward Purchaser or Forward Seller suspending activity under this

program for such period of time as requested by the Company or as deemed appropriate by such Manager, Forward Purchaser or Forward Seller

in light of the proposed sale, the Company shall not, and the Company shall not publicly disclose an intention to, sell, offer to sell,

contract or agree to sell, hypothecate, pledge, grant any option to sell or otherwise dispose of or agree to dispose of, directly or

indirectly, any shares of Common Stock or securities convertible into or exchangeable or exercisable for Common Stock or warrants or

other rights to purchase Common Stock or permit the registration under the Securities Act of any shares of Common Stock, except for (i) the

registration of the Shares and any sales through the Managers, the Forward Purchasers and the Forward Sellers pursuant to this Agreement

or any Forward Contract, (ii) the issuance of any shares of Common Stock upon settlement or termination of any Forward Contract

during the Delivery Period, (iii) the issuance of shares of Common Stock pursuant to the conversion or exchange of convertible or

exchangeable securities, the exercise of warrants or options (including through net exercise) or the settlement of restricted stock units

(including through net settlement) or the conversion, exchange, exercise or settlement of other stock-based awards, in each case outstanding

on the date of this Agreement and issued pursuant to a plan described in the Prospectus, (iv) the grant of stock options, restricted

stock, restricted stock units, or other equity-based awards and the issuance of shares of Common Stock or securities convertible into

or exercisable or exchangeable for shares of Common Stock (whether upon the exercise of stock options, settlement of restricted stock

units or otherwise) to employees, officers, directors, advisors, or consultants of the Company and its subsidiaries pursuant to the Company’s

existing equity compensation plan in effect as of the date hereof and described in the Prospectus or any assumed benefit plan pursuant

to an acquisition or similar strategic transaction, (v) the filing of any registration statement on Form S-8 relating to securities

granted or to be granted pursuant to any of the Company’s existing equity incentive and compensation plans, its savings plan and

its direct stock purchase and dividend reinvestment plan or any assumed benefit plan pursuant to an acquisition or similar strategic

transaction, (vi) the issuance and sale of shares of Common Stock (whether pursuant to physical settlement, net share settlement

or the provisions relating to acceleration events) pursuant to forward sale agreements entered into by the Company prior to the date

hereof and described in the General Disclosure Package or (vii) the issuance of shares of Common Stock upon conversion of the Company’s

convertible notes described in the General Disclosure Package.

(w)             The

Company will not, under any circumstances, (i) cause or request the offer or sale of any Shares if, after giving effect to the sale

of such Shares, the aggregate gross sales price of the Shares sold pursuant to this Agreement would exceed the lesser of (A) $500,000,000,

(B) the amount available for offer and sale under the currently effective Registration Statement, or (C) the amount authorized

from time to time to be issued and sold under this Agreement by the Board of Directors of the Company or a duly authorized committee

thereof or (ii) cause or request the offer or sale of any Shares pursuant to this Agreement at a price lower than the minimum price

authorized from time to time by the Board of Directors of the Company or a duly authorized committee thereof and notified to a Manager

or a Forward Seller, as applicable, in writing.

7.             Covenants

of the Managers, the Forward Purchasers and the Forward Sellers. Each Manager, Forward Purchaser and Forward Seller covenants with

the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) under

the Securities Act a free writing prospectus prepared by or on behalf of any Manager, Forward Purchaser or Forward Seller that otherwise

would not be required to be filed by the Company thereunder, but for the action of such Manager, Forward Purchaser or Forward Seller.

8.             Indemnity

and Contribution.

(a)             Indemnification

of the Managers, Forward Purchasers and Forward Sellers. The Company will indemnify and hold harmless each Manager, each Forward

Seller and each Forward Purchaser and their respective directors, officers and affiliates and each person, if any, who controls any Manager,

any Forward Seller or any Forward Purchaser within the meaning of the Securities Act against any losses, claims, damages or liabilities,

joint or several, to which such Manager, such Forward Seller, such Forward Purchaser, such directors and officers or such controlling

person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions

in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in

the Registration Statement, the Prospectus, the Prospectus Supplement, any Interim Prospectus Supplement, the General Disclosure Package,

any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities

Act, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material

fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Manager, each

Forward Seller and each Forward Purchaser, and their respective directors, officers and affiliates and each of their respective controlling

persons for any legal or other expenses reasonably incurred by such Manager, such Forward Seller, such Forward Purchaser, such directors,

officers and affiliates or such controlling person, as incurred, in connection with investigating or defending any such loss, claim,

damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that

any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission

or alleged omission made in any of such documents in reliance upon and in conformity with written information furnished by any Manager,

any Forward Seller or any Forward Purchaser through the Managers to the Company specifically for use therein, which information consists

solely of the information specified in Section 8(b). This indemnity agreement will be in addition to any liability that the Company

may otherwise have.

(b)             Indemnification

of the Company. Each Manager will severally and not jointly indemnify and hold harmless the Company, each Forward Seller, each Forward

Purchaser and each of their respective directors, officers who have signed the Registration Statement, and each person, if any, who controls

the Company, any Forward Seller or any Forward Purchaser, within the meaning of the Securities Act, against any losses, claims, damages

or liabilities to which the Company, such Forward Seller or such Forward Purchaser or any such director, officer or controlling person

of theirs may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions

in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in

the Registration Statement, the Prospectus, the Prospectus Supplement, any Interim Prospectus Supplement, the General Disclosure Package,

any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities

Act, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein

a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent,

but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon

and in conformity with written information furnished to the Company, such Forward Seller or such Forward Purchaser by such Manager specifically

for use therein, and will reimburse any legal or other expenses reasonably incurred, as incurred, by the Company or any such director,

officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action. This indemnity

agreement will be in addition to any liability that such Manager may otherwise have. The Company, each Forward Seller and each Forward

Purchaser acknowledge that (i) the Managers’, the Forward Purchasers’ and the Forward Sellers’ names and (ii) the

statements set forth in the third sentence of the second paragraph under the heading “Plan of Distribution (Conflicts of Interest)”

in the Prospectus constitute the only information furnished in writing by or on behalf of the several Managers for inclusion in the Registration

Statement, the Prospectus, the Prospectus Supplement, any Interim Prospectus Supplement, the General Disclosure Package, and any free

writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or

any amendment or supplement thereto.

Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified

party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying

party of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability

that it may have under Section 8(a) or Section 8(b) except to the extent that it has been materially prejudiced (including

through the forfeiture of substantive rights or defenses) by such failure; provided, further, that the failure to notify

the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under Section 8(a) or

Section 8(b). In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement

thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may 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,

without 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 assumption of the defense thereof, the indemnifying party will not be liable to such indemnified party

under this Section 8 for any legal or other expenses 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 separate counsel (including local counsel),

and the indemnifying party shall bear the reasonable and documented fees, costs and expenses of such separate counsel 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) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying

party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified

parties that 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. It is understood that the indemnifying party shall not, in respect of the legal expenses

of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and

expenses of more than one separate firm (and any local counsel) for all such indemnified parties. Such firm shall be designated in writing

by the Managers, the Forward Sellers or the Forward Purchasers, as applicable, in the case of parties indemnified pursuant to Section 8(a),

and by the Company, in the case of parties indemnified pursuant to Section 8(b). An indemnifying party shall not be liable for any

settlement of a claim or action effected without its written consent, which shall not be unreasonably withheld. No indemnifying party

shall, without the prior written consent of the indemnified parties, which consent shall not be unreasonably withheld, settle or compromise

or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which

indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such

claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from

all liability arising out of such claim, action, suit or proceeding and (ii) does not include any findings of fact or admissions

of fault or culpability as to the indemnified parties.

(d)             Contribution;

Limitation on Liability. If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless

an indemnified party for any loss, claim, damage, liability or action described in Section 8(a) or Section 8(b), then

each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages

or liabilities referred to in Section 8(a) or Section 8(b) on the following basis: (i) if such loss, claim,

damage, liability or action arises under Section 8(a), then (A) in such proportion as is appropriate to reflect the relative

benefits received by the Company, the Managers, the Forward Sellers and the Forward Purchasers, as the case may be, in connection with

the offering of the Shares or (B) if the allocation provided by clause (A) above is not permitted by applicable law, in such

proportion as is appropriate to reflect not only the relative benefits referred to in clause (A) above but also the relative fault

of the Company, the Managers, the Forward Sellers and the Forward Purchasers, as the case may be, in connection with the statements or

omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations; and (ii) if

such loss, claim, damage, liability or action arises under Section 8(b), then in such proportion as is appropriate to reflect the

relative faults of the Company, the Managers, the Forward Sellers and the Forward Purchasers in connection with the statements or omissions

that resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. For purposes of

clause (i) above, the relative benefits received by the Company, the Managers, the Forward Purchasers and the Forward Sellers shall

be equal to (a) in the case of the Company, the sum of (x) the Actual Sold Forward Amount for each Forward under this Agreement,

multiplied by the Volume-Weighted Hedge Price for such Forward, and (y) the total net proceeds from the offering of the Issuance

Shares sold by the Managers under this Agreement (before deducting expenses) received by the Company, (b) in the case of a Manager,

the total commissions received from the sale of Issuance Shares under this Agreement, (c) in the case of a Forward Seller, the Actual

Sold Forward Amount for each Forward under this Agreement, multiplied by the Forward Hedge Selling Commission for such Forward,

and (d) in the case of a Forward Purchaser, the net Spread (as such term is defined in the relevant Forward Contract and net of

any related stock borrow costs or other costs or expenses actually incurred) multiplied by the Forward Hedge Amount for each Forward

Contract executed in connection with this Agreement. For purposes of clause (i) and clause (ii) above, the relative fault shall

be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission

or alleged omission to state a material fact relates to information supplied by the Company, the Managers, the Forward Sellers or the

Forward Purchasers, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such

untrue statement or omission. The Company, each of the Managers, each of the Forward Sellers and each of the Forward Purchasers agree

that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation

(even if the Managers, the Forward Purchasers and/or the Forward Sellers were treated as one entity for such purpose) or by any other

method of allocation that does not take account of the equitable considerations referred to above in this Section 8(d). The amount

paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 8(d) shall

be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending

any action or claim that is the subject of this Section 8(d). Notwithstanding the provisions of this Section 8(d), by reason

of such untrue or alleged untrue statement or omission or alleged omission, (i) no Manager shall be required to contribute any amount

in excess of the amount by which the total price at which the Issuance Shares sold by it were offered to the public exceeds the amount

of any damages that such Manager has otherwise been required to pay, (ii) no Forward Seller shall be required to contribute any

amount in excess of the aggregate Forward Hedge Selling Commissions received by it under this Agreement and (iii) no Forward Purchaser

shall be required to contribute any amount in excess of the net Spread (as such term is defined in the relevant Forward Contract and

net of any related stock borrow costs or other costs or expenses actually incurred) multiplied by the Forward Hedge Amount for

all Forward Contracts executed in connection with this Agreement. No person guilty of fraudulent misrepresentation (within the meaning

of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent

misrepresentation. The Managers’ obligations in this Section 8(d) to contribute are several in proportion to their respective

underwriting obligations and not joint.

9.             Effectiveness.

This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

10.             Termination.

(a)             The

Company shall have the right, by giving written notice as hereinafter specified, to terminate this Agreement in its sole discretion at

any time. Any such termination shall be without liability of any party to any other party, except that (i) with respect to any pending

sale through any Manager or Forward Seller for the Company, the obligations of the Company, including, but not limited to, its obligations

under Section 4, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Section 1

and Section 8 shall remain in full force and effect notwithstanding such termination.

(b)             The

Managers, the Forward Purchasers and the Forward Sellers shall have the right, by giving written notice as hereinafter specified, to

terminate this Agreement in their sole discretion at any time. Any such termination pursuant to this Section 10 shall be without

liability of any party to any other party except that (i) with respect to any pending sale through a Manager or a Forward Seller

for the Company, the obligations of the Company, including, but not limited to, its obligations under Section 4, shall remain in

full force and effect notwithstanding such termination; and (ii) the provisions of Section 1 and Section 8 shall remain

in full force and effect notwithstanding such termination.

Agreement shall remain in full force and effect until and unless terminated pursuant to Section 10(a) or Section 10(b) or

otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement or pursuant to Section 10(a) or

Section 10(b) shall in all cases be deemed to provide that Section 1 and Section 8 shall remain in full force and

effect.

(d)             Any

termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination

shall not be effective until the close of business on the date of receipt of such notice by the Managers, the Forward Purchasers and

the Forward Sellers or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of

Shares, such sale shall settle in accordance with the provisions of Section 4.

(e)             Unless

earlier terminated pursuant to this Section 10, this Agreement shall automatically terminate upon the issuance and sale of all of

the Shares through the Managers, the Forward Purchasers and the Forward Sellers on the terms and subject to the conditions set forth

herein with an aggregate gross sales price equal to $500,000,000.

(f)             The

indemnity and contribution provisions contained in Section 8 and the representations, warranties and other statements of the Company,

the Managers, the Forward Purchasers and the Forward Sellers contained in this Agreement shall remain operative and in full force and

effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Manager, Forward

Purchaser or Forward Seller, any person controlling any Manager, Forward Purchaser or Forward Seller or any affiliate of any Manager,

Forward Purchaser or Forward Seller or by or on behalf of the Company, its officers or directors or any person controlling the Company

and (iii) acceptance of and payment for any of the Shares.

11.             Entire

Agreement.

(a)             This

Agreement represents the entire agreement between the Company and the Managers, the Forward Purchasers and the Forward Sellers with respect

to the preparation of any Registration Statement, the Prospectus Supplement or the Prospectus, the conduct of the offering and the sale

and distribution of the Shares.

(b)             The

Company acknowledges that in connection with the offering of the Shares: (i) the Managers, the Forward Purchasers and the Forward

Sellers have acted and will act at arm’s length and owe no fiduciary duties to the Company or any other person, (ii) the Managers,

the Forward Purchasers and the Forward Sellers owe the Company only those duties and obligations set forth in this Agreement, the other

Transaction Documents, any contemporaneous written agreement and prior written agreements (to the extent not superseded by this Agreement),

if any, and (iii) the Managers, the Forward Purchasers and the Forward Sellers may have interests that differ from those of the

Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Managers, the Forward Purchasers

and the Forward Sellers arising from an alleged breach of fiduciary duty in connection with the sale and distribution of the Shares.

Due Diligence Protocol

Set forth below are guidelines

for use by the Company and the Managers, the Forward Purchasers and the Forward Sellers in connection with the Managers’, the Forward

Purchasers’ and the Forward Sellers’ continuous due diligence efforts in connection with the sale and distribution of the

Shares pursuant to this Agreement. For the avoidance of doubt, the Company has agreed that no sales under this Agreement will be requested

or made at any time the Company is in possession of material non-public information with respect to the Company.

1. On or immediately prior to each Representation

Date (or such alternative date as may be chosen pursuant to Section 6(p) of this

Agreement), if the obligation to deliver or cause to be delivered the documents referred

to in Section 6(k), Section 6(l) and Section 6(o) of this Agreement

has not been waived for such Representation Date in accordance with Section 6(q), in

addition to the documents provided pursuant to Section 6(k), Section 6(l) and

Section 6(o) of this Agreement, the Managers, the Forward Purchasers and the Forward

Sellers expect to conduct a due diligence call with the appropriate business, financial and

legal representatives of the Company.

2. Subject

to Section 6(r) of this Agreement, promptly after the Company files an Annual Report

on Form 10-K or a Quarterly Report on Form 10-Q (including any date on which an

amendment to any such document is filed), the Managers, the Forward Purchasers and

the Forward Sellers expect to conduct a due diligence call with the appropriate business,

financial, accounting and legal representatives of the Company, and the Company shall provide

the certificate referred to in Section 5(b) of this Agreement.

3. In the event that the Company requests

any Manager or Forward Seller to sell on any one Trading Day an amount of Issuance Shares

or Forward Hedge Shares, respectively, that would be equal to or greater than 20% of the

average daily trading volume (calculated based on the most recent three completed Trading

Days) of the Company’s common stock, such Manager or Forward Seller expects to conduct

a due diligence call with the appropriate business, financial, accounting and legal representatives

of the Company, and the Company shall provide the certificate referred to in Section 5(b) of

this Agreement.

The foregoing is an expression of current intent

only, and shall not in any manner limit the Managers’, the Forward Purchasers’ or the Forward Sellers’ rights under

this Agreement, including the right to require such additional due diligence procedures as the Managers, the Forward Purchasers and the

Forward Sellers may reasonably request pursuant to this Agreement.

Ladies and Gentlemen:

The purpose of this letter agreement (this “Master

Forward Confirmation”) is to confirm the terms and conditions of certain transactions to be entered into from time to time

Inc., TD Securities (USA) LLC and Truist Securities, Inc., as Forward Sellers (the “Equity Distribution Agreement”),

on one or more Trade Dates specified herein (collectively, the “Transactions” and each, a “Transaction”).

This letter agreement constitutes a “Master Forward Confirmation” as referred to in the Equity Distribution Agreement. Each

Transaction will be evidenced by a supplemental confirmation (each, a “Supplemental Confirmation,” and each such Supplemental

Confirmation, together with this Master Forward Confirmation, a “Confirmation” for purposes of the Agreement specified

below) substantially in the form of Exhibit A hereto. [Party A is acting as principal in each Transaction and BMO Capital Markets

Corp., its affiliate, is acting as agent for each Transaction solely in connection with Rule 15a-6 of the Exchange Act (as defined

herein).]9

1. The definitions and provisions contained in

the 2006 ISDA Definitions (the “2006 Definitions”) and the 2002 ISDA Equity

Derivatives Definitions (the “2002 Definitions” and, together with the

2006 Definitions, the “Definitions”), each as published by the International

Swaps and Derivatives Association, Inc. (“ISDA”), are incorporated

into each Confirmation. In the event of any inconsistency among the Agreement (as defined

herein), this Master Forward Confirmation, any Supplemental Confirmation, the 2006 Definitions

and the 2002 Definitions, the following will prevail in the order of precedence indicated:

(i) such Supplemental Confirmation; (ii) this Master Forward Confirmation; (iii) the

2002 Definitions; (iv) the 2006 Definitions; and (v) the Agreement.

Each Confirmation together with the

Agreement shall evidence a complete and binding agreement between Party A and Party B as to the subject matter and terms of the Transaction

to which this Master Forward Confirmation and each related Supplemental Confirmation relate, and shall supersede all prior or contemporaneous

written or oral communications with respect thereto. Each 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 the Agreement

in such form on the date hereof (but without any Schedule except for the election of the laws of the State of New York as the governing

law (without reference to choice of law doctrine other than Article 5 of the New York General Obligations Law)). The parties hereby

agree that no transaction other than the Transactions to which this Master Forward Confirmation, together with each Supplemental Confirmation

hereunder, relate shall be governed by the Agreement. For purposes of the 2002 Definitions, each Transaction shall be a Share Forward

Transaction.

Party A and Party B each represents

to the other, with respect to each Transaction hereunder, that it has entered into such Transaction in reliance upon such tax, accounting,

regulatory, legal, and financial advice as it deems necessary and not upon any view expressed by the other.

Party A. Whenever the Calculation Agent is required to act or to exercise judgment in any way with respect to any Transaction hereunder, it will do so in good faith and in a commercially reasonable manner.

Following any determination, adjustment or calculation hereunder by the Calculation Agent, the Calculation Agent will, promptly following written request by Party B, provide to Party B a report (in a commonly used file format for the storage and manipulation of financial data but without disclosing Party A’s confidential or proprietary models or other information that may be confidential, proprietary or subject to contractual, legal or regulatory obligations to not disclose such information) displaying in reasonable detail the basis for such determination, adjustment or calculation, as the case may be.

Following the occurrence and during the continuation of an Event of Default pursuant to Section 5(a)(vii) of the Agreement with respect to which Party A is the sole Defaulting Party, Party B shall have the right to designate an independent, nationally recognized equity derivatives dealer to replace Party A as Calculation Agent, and the parties hereto shall work in good faith to execute any appropriate documentation required by such replacement Calculation Agent.

Settlement Terms:

Settlement Date:

With respect to any Transaction, any Scheduled Trading Day following the Effective Date for such Transaction up to, and including, the Maturity Date for such Transaction, 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 (i) if Physical Settlement applies, prior to 12:00 p.m. (New York City time) on the Scheduled Trading Day immediately preceding such Settlement Date, which may be the Maturity Date for such Transaction and (ii) if Cash Settlement or Net Share Settlement applies, a number of Scheduled Trading Days at least equal to the Notice Settlement Number (as defined below) for such Transaction prior to such Settlement Date, which may be the Maturity Date for such Transaction; provided that (x) the Maturity Date for such Transaction shall be a Settlement Date for such Transaction if on such date the Base Amount for such Transaction is greater than zero, (y) if Physical Settlement or Net Share Settlement applies and such Settlement Date specified above (including a Settlement Date occurring on such Maturity Date) is not a Clearance System Business Day, such Settlement Date shall be the immediately succeeding Clearance System Business Day and (z) if Cash Settlement or Net Share Settlement applies and Party A shall have fully unwound its commercially reasonable hedge position in respect of such Transaction (or portion thereof, as applicable) during an Unwind Period (as defined below) for such Transaction by a date (the “Hedge Unwind Completion Date”) that is more than one Scheduled Trading Day prior to such Settlement Date specified above, the Settlement Date for such Transaction shall be the date that follows the Hedge Unwind Completion Date for such Cash Settlement or Net Share Settlement, as the case may be, by one Settlement Cycle. The “Notice Settlement Number” for any Transaction shall be a number of Scheduled Trading Days set forth in the Supplemental Confirmation for such Transaction.

Settlement Shares:

In respect of any Transaction and with respect to any Settlement Date for such Transaction, a number of Shares, not to exceed the Base Amount for such Transaction, 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 for such Transaction the number of Settlement Shares shall be equal to the Base Amount for such Transaction on such date.

Settlement:

In respect of any Transaction, 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 for such Transaction 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, commercially reasonable judgment, to unwind its commercially reasonable hedge position in respect of such Transaction (or portion thereof, as applicable) by the end of the Unwind Period for such Transaction in a manner that, in the good faith, reasonable judgment of Party A, 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 such Unwind Period or (iii) to any Termination Settlement Date (as defined below under “Termination Settlement”).

Settlement Notice Requirements:

Notwithstanding any other provision hereof, a Settlement Notice delivered in respect of any Transaction by Party B that specifies Cash Settlement or Net Share Settlement will not be effective to establish a Settlement Date for such Transaction 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:

For any Transaction, 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 for such Transaction through the Scheduled Trading Day 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 for any Transaction is a Disrupted Day, the Calculation Agent shall make commercially reasonable adjustments to the terms of such 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)(ii) 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, acting in good faith and a commercially reasonable manner, determines is material.”

Exchange Act:

The Securities Exchange Act of 1934, as amended from time to time.

Physical Settlement:

In respect of any Transaction, on any Settlement Date for such Transaction in respect of which Physical Settlement applies, Party B shall deliver to Party A through the Clearance System the Settlement Shares for such Transaction for such Settlement Date, and Party A shall deliver 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 Transaction for such Settlement Date, on a delivery versus payment basis. If, on any Settlement Date for any Transaction, the Shares to be delivered by Party B to Party A hereunder upon Physical Settlement are not so delivered (the “Physical Deferred Shares”), and a Forward Price Reduction Date with respect to such Transaction 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 for such Transaction payable by Party A to Party B in respect of the Physical Deferred Shares shall be reduced by an amount equal to (1) the Forward Price Reduction Amount for such Forward Price Reduction Date multiplied by (2) the number of Physical Deferred Shares.

Physical Settlement Amount:

In respect of any Transaction and for any Settlement Date for such Transaction in respect of which Physical Settlement applies, an amount in cash equal to the product of (i) the Forward Price for such Transaction on such Settlement Date and (ii) the number of Settlement Shares for such Transaction for such Settlement Date.

Cash Settlement:

In respect of any Transaction, on any Settlement Date for such Transaction in respect of which Cash Settlement applies, if the Cash Settlement Amount for such Transaction for such Settlement Date is a positive number, Party A will pay such Cash Settlement Amount to Party B. If the Cash Settlement Amount for such Transaction is a negative number, Party B will pay the absolute value of such Cash Settlement Amount to Party A. Such amounts shall be paid on the relevant Settlement Date.

Cash Settlement Amount:

In respect of any Transaction and for any Settlement Date for such Transaction 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 for such Transaction over the period beginning on, and including, the date that is one Settlement Cycle following the first day of the applicable Unwind Period for such Transaction and ending on, and including, such Settlement Date (calculated assuming no reduction to such Forward Price for any Forward Price Reduction Date that occurs during such Unwind Period, except as set forth in clause (2) below), minus the Commission (as defined below), minus (B) the average of the 10b-18 VWAP prices per Share on each Exchange Business Day during such Unwind Period (the “Average Unwind Period 10b-18 VWAP”) and (ii) the number of Settlement Shares for such Transaction for such Settlement Date and (2) the product of (i) the Forward Price Reduction Amount for any Forward Price Reduction Date that occurs during such Unwind Period and (ii) the number of Settlement Shares for such Transaction with respect to which Party A has not unwound its commercially reasonable hedge position as of such Forward Price Reduction Date.

Net Share Settlement:

In respect of any Transaction, on any Settlement Date for such Transaction in respect of which Net Share Settlement applies, if the number of Net Share Settlement Shares for such Transaction is a (i) positive number, Party A shall deliver to Party B such Net Share Settlement Shares, or (ii) negative number, Party B shall deliver a number of Shares to Party A equal to the absolute value of such Net Share Settlement Shares; provided that if Party A determines in its good faith, commercially reasonable 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. If, on any Settlement Date for any Transaction, 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 with respect to such Transaction 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 for such Transaction 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 Forward Price Reduction Amount for such Forward Price Reduction Date.

Net Share Settlement Shares:

In respect of any Transaction and for any Settlement Date in respect of which Net Share Settlement applies, a number of Shares equal to (i) the Cash Settlement Amount in respect of such Settlement Date divided by (ii) the Average Unwind Period 10b-18 VWAP, with the number of Shares rounded up in the event such calculation results in a fractional number of Shares.

10b-18 VWAP:

For any Exchange Business Day during an 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 published by Bloomberg L.P. or its successor at 4:15 p.m. New York time (or 15 minutes following the end of any extension of the regular trading session) on such Exchange Business Day, on Bloomberg page “PNW <Equity> AQR SEC” (or any successor thereto), or if such price is not so reported on such Exchange Business Day for any reason or is, in the Calculation Agent’s reasonable determination, erroneous, such 10b-18 VWAP shall be as determined by the Calculation Agent in good faith and in a commercially reasonable manner including only those trades that are reported during the period of time during which Party B could purchase its own shares under Rule 10b-18(b)(2) and effected pursuant to the conditions of Rule 10b-18(b)(3), each under the Exchange Act.

Commission:

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

All Shares so issuable shall, upon such issuance, be accepted for listing or quotation on

the Exchange. Party B shall have submitted an application for the listing of the Forward

any Supplemental Confirmation, under an agreement with another party or otherwise, that might

cause any purchases of Shares by Party A or any of its affiliates in connection with any

Cash Settlement or Net Share Settlement of any Transaction hereunder 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 and Rule 10b-18 were applicable to such purchases.

(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 for any Transaction hereunder.

(i) In addition to any other requirements set

forth herein, Party B agrees not to elect Cash Settlement or Net Share Settlement in respect

of any Transaction if, in the good faith, reasonable judgment of either Party A or Party

in relation to each 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 for each Transaction and the 10b-18 VWAP for each Transaction;

(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

Additional Mutual Representation

and Warranty:

Each party represents and warrants to the other

party that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange

Act, as amended).

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 for

a Transaction hereunder 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 such Transaction will be freely

saleable without further registration or other restrictions under the Securities Act, in the hands of those securities lenders, 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 for a Transaction

hereunder 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 for a Transaction hereunder to return

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 Master Forward Confirmation and the relevant Supplemental

Confirmation.

(b) In connection with bids and purchases of

Shares in connection with any Cash Settlement or Net Share Settlement of any 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.

nature of its business, reasonably designed to ensure that individuals conducting hedging

activity related to any Transaction do not have access to material non-public information

regarding Party B or the Shares.

Insolvency

Notwithstanding anything to the contrary

herein, in any Supplemental Confirmation, in the Agreement or in the Definitions, upon any Insolvency Filing in respect of Party B, each

Transaction hereunder shall automatically terminate on the date thereof without further liability of either party to this Master Forward

Confirmation or any related Supplemental Confirmation to the other party (except for any liability in respect of any breach of representation

or covenant by a party under this Master Forward Confirmation or any Supplemental Confirmation prior to the date of such Insolvency Filing).

Extraordinary Dividends:

If an ex-dividend date for an Extraordinary

Dividend occurs on or after the Trade Date for any Transaction and on or prior to the Maturity Date for such Transaction (or, if later,

the last date on which Shares are delivered by Party B to Party A in settlement of such Transaction), Party B shall pay an amount, as

determined by the Calculation Agent in a commercially reasonable manner, in cash equal to the product of (1) the per Share amount

of such Extraordinary Dividend and (2) the Base Amount for such Transaction to Party A on the earlier of (i) the date

on which such Extraordinary Dividend is paid by Party B to holders of record of the Shares or (ii) the Maturity Date for such Transaction.

“Extraordinary Dividend” means the per Share amount of any cash dividend or distribution, or a portion thereof, declared

by Party B with respect to the Shares that is specified by the board of directors of Party B as an “extraordinary” dividend.

For the avoidance of doubt, a regular, quarterly cash dividend that is in an amount per Share equal to or less than the Forward Price

Reduction Amount corresponding to the relevant quarter and that has an ex-dividend date not earlier than the Forward Price Reduction

Date corresponding to the relevant quarter shall not be an Extraordinary Dividend.

Acceleration Events:

The following events shall each constitute an “Acceleration

Event” with respect to any Transaction:

(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 such Transaction because of the lack of sufficient

Shares being made available for Share borrowing by lenders, or (ii) Party A (or its

affiliate) would incur a Stock Loan Fee to borrow a number of Shares equal to the Base Amount

for such Transaction of more than a rate equal to the Maximum Specified Borrow Rate for such

Transaction (each, a “Stock Borrow Event”);

(b) Dividends and Other Distributions.

On any day occurring after the Trade Date for such Transaction, 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 for such Transaction

(with the Trade Date for such Transaction 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 to the relevant Supplemental Confirmation,

(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 the Calculation Agent;

A has the right to designate an Early Termination Date pursuant to Section 6 of the

Agreement, in which event, except as otherwise specified in this Master Forward Confirmation

and except as a result of an Event of Default under Section 5(a)(i) of the Agreement,

the provisions specified under “Termination Settlement” below shall apply in

lieu of the consequences specified in 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 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

with 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 Forward Date for such Transaction”; 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).

The “Maximum Specified Borrow

Rate” for any Transaction shall be the per annum rate set forth in the Supplemental Confirmation for such Transaction.

The “Share Amount”

as of any day is the number of Shares that Party A 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, 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 Shares under any Applicable Restriction, as determined by Party A in its reasonable discretion. The “Post-Effective Limit”

means a number of Shares equal to (x) the minimum number of Shares that could reasonably be expected to give rise to reporting or

registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Party A Person, or

could reasonably be expected to result in an adverse effect on a Party A Person, under any Applicable Restriction, as determined by Party

A in its reasonable discretion, minus (y) 1% of the number of Shares outstanding.

Termination Settlement:

Upon the occurrence of any Acceleration

Event in respect of any Transaction, 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 under such Transaction (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 for the relevant Transaction 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 for the relevant Transaction 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 relevant 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 for any Transaction relating to a number of Settlement

Shares for the relevant Transaction 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 such 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. Under no circumstances will Party A be entitled to an adjustment to the terms

of any Transaction for the effects of an Extraordinary Dividend (other than as set forth above under the heading “Extraordinary

Dividends”) or a change in expected dividends. For the avoidance of doubt, the immediately preceding sentence shall not preclude

or otherwise limit Party A from exercising its “Termination Settlement” rights pursuant to this paragraph upon the occurrence

of an Acceleration Event as set forth in clause (b) of such definition.

Private Placement Procedures:

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, but Party A may not otherwise determine that the Settlement Shares

are Restricted Shares based solely upon Party A (or its affiliates) not having borrowed a number of Shares equal to the Base Amount for

the relevant Transaction on or before the Effective Date for such Transaction if there has been no change in law or 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 Master Forward Confirmation

and each Supplemental 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 Master Forward Confirmation or any Supplemental Confirmation

and (ii) Party B is entering into the Agreement, this Master Forward Confirmation and each Supplemental 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.

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 any Permitted]24 EDG Personnel (as defined below). For purposes of each 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, or contained in a public filing made by Party B with the Securities and Exchange Commission, or otherwise disseminated

in a manner constituting “public disclosure” within the meaning of Regulation FD under the Exchange Act 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 customers, significant merger or acquisition proposals or agreements, significant new supply shortages

or disruptions, extraordinary borrowing, major litigation, liquidity problems, extraordinary management developments, purchase or sale

of substantial assets, or other similar information. [For purposes of each Transaction, “EDG Personnel” means any

employee on the trading side of the Equity Derivatives Group of Bank of Montreal and does not include any member of Bank of Montreal’s

legal department, Brian Riley, Jeff Brunswick, Rahim Kara, Cameron Fisher, Ben Wang or any other person or persons designated from time

to time in writing to Party B by Party A.]25 [For purposes of each Transaction, “Permitted EDG Personnel”:

Maximum Share Delivery:

Notwithstanding any other provision of

this Master Forward Confirmation or any Supplemental Confirmation, in no event will Party B be required to deliver on any Settlement

Date for any Transaction hereunder, whether pursuant to Physical Settlement, Net Share Settlement, Termination Settlement or any Private

Placement Settlement, more than a number of Shares equal to the Forward Shares for such Transaction to Party A. The “Forward

Shares” for any Transaction shall be as set forth in the Supplemental Confirmation for such Transaction.

Interpretive Letter:

The parties intend this Master Forward

Confirmation to constitute a “Contract” as described in the letter dated October 6, 2003 submitted on behalf of Goldman,

Sachs & Co. to Paula Dubberly of the staff of the Securities and Exchange Commission (the “Staff”) to which

the Staff responded in an interpretive letter dated October 9, 2003 (the “Interpretive Letter”).

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 or any entity organized or sponsored by Party A (a “Transferee”)

without the prior written consent of Party B so long as (a)(i) the Transferee has at the time of the assignment or transfer a senior

unsecured debt rating by at least one of Moody’s Investors Services, Inc. or Standard & Poor’s Inc. (the “Credit

Rating”) equal to or higher than the Credit Rating of Party A or (ii) the Transferee’s obligations are fully and

unconditionally guaranteed by Party A or, if Party A’s ultimate parent entity satisfies the Credit Rating requirements that would

otherwise apply to a Transferee, by Party A’s ultimate parent entity without the prior written consent of Party B; (b) Party

B will not (including, for the avoidance of doubt, after giving effect to any indemnity from the Transferee to Party B provided in connection

with such transfer or assignment) be required to pay (including a payment in kind) 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 (including a payment in kind) Party A in the absence of such assignment or transfer; (c) Party B will

not (including, for the avoidance of doubt, after giving effect to any indemnity from the transferee or assignee to Party B provided

in connection with such transfer or assignment) receive a payment (including a payment in kind) from which an amount has been withheld

or deducted on account of a Tax (after accounting for amounts paid by the transferee or assignee under Section 2(d)(i)(4) 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; (d) no Acceleration Event or other event or circumstance giving rise to a right or responsibility to terminate or cancel

any Transaction hereunder will occur as a result of such assignment or transfer; and (e) such transfer does not materially and adversely

affect the availability of the relief provided in the Interpretive Letter or the application thereof to such Transaction in the manner

contemplated by Party B on the applicable Trade Date. Notwithstanding any other provision in this Master Forward 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 a 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 (within the meaning of Rule 405 under the Securities Act), directors, officers and each person, if any, who controls

Party A (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) (Party A and each

such affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities

(including reasonable and documented legal fees and expenses of a single counsel for all Indemnified Parties), joint or 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 Master Forward Confirmation, any Supplemental Confirmation or the Agreement. If for any reason the foregoing

indemnification is unavailable to any Indemnified Party or is insufficient to hold harmless any Indemnified Party, then Party B shall

contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss,

claim, damage or liability. In addition, Party B will reimburse any Indemnified Party for all reasonable and documented expenses as they

are incurred in connection with the investigation of and defense of any claim or any action or proceeding arising therefrom, whether

or not such Indemnified Party is a party thereto. 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, willful misconduct or bad faith, or from a breach of any representation or covenant of Party A contained in this Master Forward

Confirmation, any Supplemental Confirmation or the Agreement. In no case will Party B be liable with respect to any claims made against

an Indemnified Party unless such Indemnified Party shall have notified Party B in writing within a reasonable time after the summons

or other first legal process giving information of the nature of the claim shall have been served upon such Indemnified Party, but failure

to notify Party B of any such claim (i) shall not relieve Party B from liability under this paragraph unless and to the extent Party

B did not otherwise learn of such claim and such failure results in the forfeiture by Party B of substantial rights and defenses and

(ii) shall not relieve Party B from any liability which it may have to such Indemnified Party otherwise than on account of the indemnity

agreement contained in this paragraph.

Party B will be entitled to participate

at its own expense in the defense, or, if it so elects, to assume the defense of any suit brought to enforce any such liability, but,

if Party B elects to assume the defense, such defense shall be conducted by counsel chosen by it; provided, however, that such

counsel shall be reasonably satisfactory to Party A. In the event that Party B elects to assume the defense of any such suit and retains

such counsel, Party A or affiliate or affiliates, director or directors, officer or officers, controlling person or persons, defendant

or defendants in the suit, may retain additional counsel but shall bear the fees and expenses of such counsel unless (i) Party B

shall have specifically authorized the retaining of such counsel or (ii) the parties to such suit include Party A or affiliate or

affiliates, director or directors, officer or officers or controlling person or persons and Party A or affiliate or affiliates, director

or directors, officer or officers or controlling person or persons and Party B have been advised by such counsel that one or more legal

defenses may be available to it or them which may not be available to Party B, in which case Party B shall not be entitled to assume

the defense of such suit on behalf of Party A or affiliate or affiliates, director or directors, officer or officers or controlling person

or persons, notwithstanding Party B’s obligation to bear the reasonable and documented fees and expenses of such counsel, it being

understood, however, that Party B shall not, in connection with any one such suit or proceeding or separate but substantially similar

or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for

the reasonable and documented fees and expenses of more than one separate firm of attorneys (and not more than one local counsel) at

any time for Party A or affiliate or affiliates, director or directors, officer or officers or controlling person or persons, which firm

shall be designated in writing by Party A. Party B shall not be liable to indemnify any person for any settlement of any such claim effected

without Party B’s prior written consent, which consent shall not be unreasonably withheld. Party B shall not, without the prior

written consent of Party A or affiliate or affiliates, director or directors, officer or officers or controlling person or persons, effect

any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of

which Party A or affiliate, director, officer or controlling person is or could have been a party and indemnity was or could have been

sought hereunder by Party A or affiliate, director, officer or controlling person, unless such settlement, compromise or consent (x) includes

an unconditional release of Party A or affiliate, director, officer or controlling person from all liability on claims that are the subject

matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a

failure to act by or on behalf of Party A or affiliate, director, officer or controlling person.

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 under the

Transactions are not secured by any collateral. Obligations under the Transactions shall not be set off against any other obligations

of the parties, whether arising under the Agreement, under this Master Forward Confirmation, under any Supplemental 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 any Transaction, whether arising under the Agreement, under this Master Forward Confirmation, under any

Supplemental 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 with respect to any Transaction,

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) such 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

neither this Master Forward Confirmation nor any Supplemental Confirmation is 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 Master Forward Confirmation, any Supplemental 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 Transactions.

Limit on Beneficial

Ownership:

Notwithstanding any other provisions

hereof, Party A shall not have an “interest” in (within the meaning of NYSE Rule 312.04(e)) Shares hereunder and Party

A shall not be entitled to take delivery of any Shares deliverable hereunder in respect of any Transaction (in each case, 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, (i) the Share Amount would exceed

the Post-Effective Limit for such Transaction, (ii) the Section 16 Percentage would exceed 7.5% or (iii) Party A and each

person subject to aggregation of Shares with Party A under Section 13 or Section 16 of the Exchange Act and rules promulgated

thereunder (the “Party A Group”) would directly or indirectly beneficially own (as such term is defined for purposes

of Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) in excess of the Threshold Number of

Shares for such Transaction. Any purported delivery hereunder in respect of any Transaction shall be void and have no effect to the extent

(but only to the extent) that, after such delivery, (i) the Share Amount would exceed the Post-Effective Limit for such Transaction,

(ii) the Section 16 Percentage would exceed 7.5% or (iii) Party A Group would directly or indirectly so beneficially own

in excess of the Threshold Number of Shares for such Transaction. If any delivery owed to Party A hereunder in respect of any Transaction

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, (i) the Share Amount would not exceed the Post-Effective Limit for such Transaction,

(ii) the Section 16 Percentage would not exceed 7.5% and (iii) Party A Group would not directly or indirectly so beneficially

own in excess of the Threshold Number of Shares for such Transaction. The “Threshold Number of Shares” for any Transaction

means a number of Shares equal to 4.9% of the outstanding Shares on the Trade Date for such Transaction and shall be specified for each

such Transaction in the relevant Supplemental Confirmation for such Transaction. 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.

Other Forward

Transactions:

Party A acknowledges that Party B has

entered into or may in the future enter into one or more similar forward transactions on the Shares (each, an “Other Forward”

and, collectively, the “Other Forwards”) with one or more other forward purchasers. Party A and Party B agree that

if Party B designates a “Settlement Date” (or equivalent concept) with respect to one or more Other Forwards for which “Cash

Settlement” (or equivalent concept) or “Net Share Settlement” (or equivalent concept) is applicable, and the resulting

“Unwind Period” (or equivalent concept) for such Other Forward(s) coincides for any period of time with an Unwind Period

for this Transaction (the “Overlap Unwind Period”), Party B shall notify Party A at least one Scheduled Trading Day

prior to the commencement of such Overlap Unwind Period of the first Scheduled Trading Day and the length of such Overlap Unwind Period,

and Party A shall be permitted to purchase Shares to unwind its hedge in respect of this Transaction only on alternating Scheduled Trading

Days during such Overlap Unwind Period, as notified to Party A by Party B at least one Exchange Business Day prior to such Overlap Unwind

Period (which alternating Scheduled Trading Days, for the avoidance of doubt, shall be every other Scheduled Trading Day if there is

only one Other Forward, every third Scheduled Trading Day if there are two Other Forwards, etc.).

New York General

Obligations Law:

Party B and Party A agree and acknowledge

that: (A) the Transactions contemplated by this Master Forward Confirmation will be entered into in reliance on the fact that this

Master Forward Confirmation and each Supplemental Confirmation hereto form a single agreement between Party B and Party A, and Party

A would not otherwise enter into such Transactions; (B) this Master Forward Confirmation, together with each Supplemental Confirmation

hereto, is a “qualified financial contract”, as such term is defined in Section 5-701(b)(2) of the New York General

Obligations Law; (C) each Supplemental Confirmation hereto, regardless of whether transmitted electronically or otherwise, constitutes

a “confirmation in writing sufficient to indicate that a contract has been made between the parties” hereto, as set forth

in Section 5-701(b)(3)(b) of the New York General Obligations Law; and (D) this Master Forward Confirmation and each Supplemental

Confirmation hereto constitute a prior “written contract”, as set forth in Section 5-701(b)(1)(b) of the New York

General Obligations Law, and each party hereto intends and agrees to be bound by this Master Forward Confirmation and such Supplemental

Confirmation.

Forward Placement

Notices:

Party B and Party A agree that, upon

the effectiveness of any accepted Forward Placement Notice relating to a Forward (as such term is defined in the Equity Distribution

Agreement), in respect of the Transaction to which such accepted Forward Placement Notice relates, each of the representations, warranties,

covenants, agreements and other provisions of this Master Forward Confirmation and the Supplemental Confirmation for such Transaction

(including, without limitation, the provisions above in Section 3 of this Master Forward Confirmation under the heading “Extraordinary

Dividends,” Party A’s right to designate a Termination Settlement Date in respect of such Transaction and the termination

of such Transaction following an Insolvency Filing) shall govern, and be applicable to, such Transaction as of the first Trading Day

of the Forward Hedge Selling Period for such Transaction as if the Trade Date for such Transaction were such first Trading Day. Notwithstanding

anything to the contrary in this Master Forward Confirmation, any Supplemental Confirmation, the Agreement, or the Definitions, if Party

A designates a Termination Settlement Date with respect to a Transaction (1) following the occurrence of an Event of Default or

Termination Event, other than an Insolvency Filing, and such Termination Settlement Date is to occur before the date that is one Settlement

Cycle after the last day of the Forward Hedge Selling Period for such Transaction or (2) prior to Party B’s execution of the

Supplemental Confirmation relating to such Transaction, then, for purposes of such Termination Settlement Date, a Supplemental Confirmation

relating to such Transaction reasonably completed by Party A (as if the Trade Date for such Transaction were the last day of the Forward

Hedge Selling Period on which the Forward Seller sold Forward Hedge Shares for such Transaction) shall, notwithstanding the provisions

under “Conditions to Effectiveness” above, be deemed to be immediately effective.

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

Master Forward Confirmation, any Supplemental Confirmation or the Agreement, as applicable, arising from a termination event, force majeure,

illegality, increased costs, regulatory change or similar event under this Master Forward Confirmation, any Supplemental 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)).

to a trial by jury in respect of any suit, action or proceeding relating to this Master Forward

Confirmation and/or any Supplemental Confirmation. Each party (i) certifies that

no representative, agent or attorney of the other party has represented, expressly or otherwise,

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, reasonable

due diligence rights (for Party A or any designated buyer of the Restricted Shares by Party

A), customary 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 and/or the Forward Price for the relevant Transaction

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. Notwithstanding the Agreement,

this Master Forward Confirmation or any Supplemental 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 for the relevant Transaction or Termination

Settlement Date for the relevant Transaction that would otherwise be applicable.

(ii) If Party B delivers any Restricted Shares

in respect of any 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).
