Potential Adjustment Events:

Method of Adjustment:

(i) if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 14.05 of the Indenture, Section 14.07 of the Indenture or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will determine (A) an adjustment to be made to any one or more of the Strike Price, Number of Options and/or Option Entitlement in a commercially reasonable manner and (B) a proportionate adjustment to be made to the Cap Price to the extent any adjustment is made to the Strike Price pursuant to clause (A) above (which adjustment, for the avoidance of doubt, shall not prohibit the Calculation Agent from making any further adjustments to the Cap Price in accordance with, and subject in all respects to, Section 9(x)); provided that in no event shall the Cap Price be less than the Strike Price; provided further that, notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the Indenture because the relevant “Holder” (as such term is defined in the Indenture) was deemed to be a record owner of the underlying Shares on the relevant Conversion Date pursuant to Section 14.04(f) of the Indenture, then the Calculation Agent shall make an adjustment, as determined by it, to the terms hereof in order to account for such Potential Adjustment Event;

(ii)  in connection with any Potential Adjustment Event as a result of an event or condition set forth in Section 14.04(b) of the Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section 14.04(b) of the Indenture) or “SP0” (as such term is used in Section 14.04(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

(iii)  if any Potential Adjustment Event is declared and (a) the event or condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as defined in the Indenture) is adjusted as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “Potential Adjustment Event Change”) then, in each case, the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities as a result of such Potential Adjustment Event Change.

Representations and Warranties of Counterparty.

Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Counterparty hereunder will conflict with or result in a breach of (i) the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, (ii) any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or (iii) any agreement or instrument filed as an exhibit to Counterparty’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (as updated by any subsequent filings) to which Counterparty or any of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under,

No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws.

Counterparty is not and, after consummation of the transactions contemplated hereby, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

Counterparty is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended, other than a person that is an eligible contract participant under Section 1a(18)(C) of the Commodity Exchange Act).

Each of it and its affiliates is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares.

The documents incorporated by reference in the Offering Memorandum, when they were filed with the U.S. Securities and Exchange Commission, conformed in all material respects to the requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Offering Memorandum does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

To Counterparty’s knowledge, no state or local (including any non-U.S. jurisdiction’s) law, rule, regulation or regulatory order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) by Dealer as a result of Dealer owning or holding (however defined) Shares except for the reporting requirements of the Exchange Act and the rules promulgated thereunder; provided that Counterparty makes no representation or warranty regarding any such requirement that is applicable generally to the ownership of equity securities by Dealer solely as a result of it being a financial institution or broker-dealer.

Counterparty understands that no obligations of Dealer to it hereunder will be entitled to the benefit of deposit insurance and that such obligations as of the date hereof are not guaranteed by any Affiliate of Dealer or any governmental agency.

COUNTERPARTY UNDERSTANDS THAT THE TRANSACTION IS SUBJECT TO COMPLEX RISKS THAT MAY ARISE WITHOUT WARNING AND MAY AT TIMES BE VOLATILE AND THAT LOSSES MAY OCCUR QUICKLY AND IN UNANTICIPATED MAGNITUDE AND IS WILLING TO ACCEPT SUCH TERMS AND CONDITIONS AND ASSUME (FINANCIALLY AND OTHERWISE) SUCH RISKS.

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

Counterparty is not as of the Trade Date, and Counterparty shall not be after giving effect to the transactions contemplated hereby, “insolvent” (as such term is defined in Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)) and Counterparty would be able to purchase 8,100,485 Shares in compliance with the laws of the jurisdiction of Counterparty’s incorporation or organization.

Counterparty understands, agrees and acknowledges that Dealer has no obligation or intention to register the Transaction under the Securities Act, any state securities law or other applicable federal securities law.

Without limiting the generality of Section 3(a)(iii) of the Agreement, the Transaction will not violate Rule 13e-1 or Rule 13e-4 under the Exchange Act.

Counterparty has received, read and understands the OTC Options Risk Disclosure Statement provided by Dealer and a copy of the most recent disclosure pamphlet prepared by The Options Clearing Corporation entitled “Characteristics and Risks of Standardized Options”.

The assets of Counterparty do not constitute “plan assets” under the Employee Retirement Income Security Act of 1974, as amended, the Department of Labor Regulations promulgated thereunder or under similar law.

Counterparty represents and warrants that it and any of its subsidiaries has not applied, and shall not, until after the first date on which no portion of the Transaction remains outstanding following any final exercise and settlement, cancellation or early termination of the Transaction, apply, for a loan, loan guarantee, direct loan (as that term is defined in the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”)) or other investment, or to receive any financial assistance or relief under any program or facility (collectively “Financial Assistance”) that (a) is established under applicable law (whether in existence as of the Trade Date or subsequently enacted, adopted or amended), including without limitation the CARES Act and the Federal Reserve Act, as amended, and (b) (i) requires under applicable law (or any regulation, guidance, interpretation or other pronouncement of a governmental authority with jurisdiction for such program or facility) as a condition of such Financial Assistance, that the Counterparty comply with any requirement not to, or otherwise agree, attest, certify or warrant that it has not, as of the date specified in such condition, repurchased, or will not repurchase, any equity security of Counterparty, and that Counterparty has not, as of the date specified in the condition, made a capital distribution or will make a capital distribution, or (ii) where the terms of the Transaction would cause Counterparty to fail to satisfy any condition for application for or receipt or retention of the Financial Assistance (collectively “Restricted Financial Assistance”); provided, that Counterparty or any of its subsidiaries may apply for Restricted Financial Assistance if Counterparty either (a) determines based on the advice of outside counsel of national standing that the terms of the Transaction would not cause Counterparty or any of its subsidiaries to fail to satisfy any condition for application for or receipt or retention of such Financial Assistance based on the terms of the program or facility as of the date of such advice or (b) delivers to Dealer evidence or other guidance from a governmental authority with jurisdiction for such program or facility that the Transaction is permitted under such program or facility (either by specific reference to the Transaction or by general reference to transactions with the attributes of the Transaction in all relevant respects).

Other Provisions.

[Reserved].

Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than 81.1 million (in the case of the first such notice) or (ii) thereafter more than 5.6 million less than the number of Shares included in the immediately preceding Repurchase Notice. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective

Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Exchange Act, of any securities of Counterparty, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

No Manipulation. Counterparty is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

Transfer or Assignment.

Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited to the following conditions:

With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(n) or 9(s) of this Confirmation;

Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended (the “Code”));

Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any reasonable documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as are reasonably requested and reasonably satisfactory to Dealer;

Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment;

An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment;

Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (A) without Counterparty’s consent to any affiliate of Dealer (1) that has a long-term issuer rating or a rating for its long-term, unsecured and unsubordinated indebtedness, in either case, that is equal to or better than Dealer’s credit rating at the time of such transfer or assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by Dealer or Dealer’s ultimate parent, or (B) with Counterparty’s consent (such consent not to be unreasonably withheld or delayed) to any other third party with a long-term issuer rating or a rating for its long-term, unsecured and unsubordinated indebtedness, as the case may be, equal to or better than the lesser of (1) the credit rating of Dealer at the time of such transfer or assignment and (2) A- by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”) or A3 by Moody’s Investor Service, Inc. (“Moody’s”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that any transfer or assignment described in clause (A) or (B) above shall not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code; provided further that (x) Counterparty will not be required, as a result of such

Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations; provided that Counterparty shall have recourse to Dealer in the event of failure by such designee to perform any of such obligations hereunder. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance to Counterparty by such affiliate of Dealer.

Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s hedging activities hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows:

in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date;

the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; and

if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case may be, will apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above.

Agency. Royal Bank of Canada has appointed as its agent, its indirect wholly-owned subsidiary, RBC Capital Markets, LLC (“RBCCM”), for purposes of conducting on Dealer’s behalf, a business in privately negotiated transactions in options and other derivatives. Counterparty hereby is advised that Dealer, the principal and stated counterparty in such transactions, duly has authorized RBCCM to market, structure, negotiate, document, price, execute and hedge transactions in over-the-counter derivative products. RBCCM has full, complete and unconditional authority to undertake such activities on behalf of Dealer. RBCCM acts solely as agent and has no obligation, by way of issuance, endorsement, guarantee or otherwise with respect to the performance of either party under the Transaction. The Transaction is not insured or guaranteed by RBCCM.

[Reserved.]

Additional Termination Events.

Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion in respect of which a “Notice of Conversion” (as such term is defined in the Indenture) that is effective as to Counterparty has been delivered by the relevant converting “Holder” (as such term is defined in the Indenture):

Counterparty shall, within five Scheduled Trading Days of the Conversion Date for such Early Conversion, provide written notice (an “Early Conversion Notice”) to Dealer specifying the number of Convertible Notes surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), and the giving of such Early Conversion Notice shall constitute an Additional Termination Event as provided in this clause (i);

upon receipt of any such Early Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related settlement date for such Affected Convertible Notes) with respect to the portion of the Transaction corresponding to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) the number of Affected Convertible Notes and (y) the Number of Options as of the Conversion Date for such Early Conversion;

any payment hereunder with respect to such termination (the “Conversion Unwind Payment”) shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction (and the provisions of Section 9(l) shall not apply to any amount that is payable by Dealer to Counterparty pursuant to this Section 9(i)(i)); provided that the Conversion Unwind Payment (determined, for the avoidance of doubt, without regard to Section 9(i)(i)(E) below) shall not be greater than (1) the Applicable Percentage, multiplied by (2) the Affected Number of Options, multiplied by (3) (x) the sum of (i) the amount of cash paid (if any) to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the number of Shares delivered (if any) to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note, multiplied by the fair market value of one Share as determined by the Calculation Agent, minus (y) USD 1,000;

for the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction pursuant to Section 6 of the Agreement, the Calculation Agent shall assume that (x) the relevant Early Conversion and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (y) no adjustments to the “Conversion Rate” (as defined in the Indenture) have occurred pursuant to any Excluded Provision and (z) the corresponding Convertible Notes remain outstanding;

if Counterparty has elected (or is deemed to have elected) to settle its conversion obligations in respect of the relevant Affected Convertible Notes (i) by Settlement in Shares or (ii) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Indenture, then, in lieu of paying the Conversion Unwind Payment entirely in cash as contemplated by the preceding provisions of this Section 9(i)(i), Dealer shall pay and/or deliver to Counterparty, on the date such Conversion Unwind Payment would otherwise be due (or within a commercially reasonable period of time thereafter, after taking into account existing liquidity conditions and Dealer’s hedging and hedge unwind activity or settlement activity in connection with such delivery) (A) in the case where Counterparty has elected (or is deemed to have elected) to settle its conversion obligations in respect of the relevant Affected Convertible Notes (1) by Settlement in Shares or (2) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Indenture with a Specified Cash Amount equal to or less than USD 1,000, a

the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such Early Conversion, the Number of Options shall be reduced by the Affected Number of Options.

Notwithstanding anything to the contrary in this Confirmation if an event of default with respect to Counterparty occurs under the terms of the Convertible Notes as set forth in Section 6.01 of the Indenture, and such event of default results in the Convertible Notes becoming or being declared due and payable pursuant to the Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement (which Early Termination Date shall be on or as promptly as reasonably practicable after the date on which Dealer becomes aware of the occurrence of such acceleration).

Promptly (but in any event within five Scheduled Trading Days) following any Repurchase Event (as defined below), Counterparty (x) in the case of a Repurchase Event resulting from the repurchase of any Convertible Notes upon the occurrence of a “Fundamental Change” (as defined in the Indenture) or in connection with an “Optional Redemption” (as defined in the Indenture), shall notify Dealer in writing of such Repurchase Event and (y) in the case of a Repurchase Event not described in clause (x) above, Counterparty may notify Dealer of such Repurchase Event, in each case, including the aggregate principal amount of Convertible Notes subject to such Repurchase Event (any such notice, a “Convertible Notes Repurchase Notice”); provided that any such Convertible Notes Repurchase Notice for a Repurchase Event described in clause (x) above shall contain an acknowledgment by Counterparty of its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act and the rules and regulations thereunder, and in respect of such Convertible Notes Repurchase Notice for a Repurchase Event described in clause (y) above shall not be effective unless it contains the representation by Counterparty set forth in Section 8(f) as of the date of such Convertible Notes Repurchase Notice; provided further that any “Convertible Notes Repurchase Notice” delivered to Dealer pursuant to the Base Call Option Confirmation shall be deemed to be a Convertible Notes Repurchase Notice pursuant to this Confirmation and the terms

Amendments to Equity Definitions.

Section 11.2(e)(vii) of the Equity Definitions is hereby amended by (x) inserting the words “similar corporate” immediately prior to the word “event”; (y) deleting the words “diluting or concentrative” and replacing them with the word “material”; and (z) adding the phrase “or the Options” at the end of the sentence.

Section 12.9(b)(i) of the Equity Definitions is hereby amended by replacing “either party may elect” with “Dealer may elect or, if Counterparty represents that it and its officers and directors are not aware of any material nonpublic information with respect to Counterparty or the Shares, Counterparty may elect,”.

Section 12.1(d) of the Equity Definitions is hereby amended by replacing “10%” with “15%”.

Section 11.2(e)(v) of the Equity Definitions is hereby amended by adding the phrase “, provided that, notwithstanding this Section 11.2(e)(v), the parties hereto agree that, with respect to the Transaction, the following repurchases of Shares by the Issuer or any of its subsidiaries shall not be considered Potential Adjustment Events: any repurchases of Shares in open-market transactions at prevailing market prices or privately negotiated accelerated Share repurchase (or similar) transactions that are entered into at prevailing market prices and in accordance with customary market terms for transactions of such type to repurchase the Shares, in each case, to the extent that, after giving effect to such transactions, the aggregate number of Shares repurchased during the term of the Transaction pursuant to all transactions described in this proviso would not exceed 15% of the number of Shares outstanding as of the Trade Date, as determined by the Calculation Agent” at the end of such Section.

No Collateral or Setoff. Neither party shall have the right to set off any obligation that it may have to the other party under the Transaction against any obligation such other party may have to it, whether arising under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of law or otherwise.

Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) and 6(e) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the date of the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply, (b) Counterparty remakes the representation set forth in Section 8(f) as of the date of such election and (c) Dealer agrees, in its commercially reasonable discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) and 6(e) of the Agreement, as the case may be, shall apply.

Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, based on the advice of counsel, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of a similar size; provided, however, that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size, in form and substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its commercially reasonable judgment, to account for any commercially reasonable discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or (iii) purchase the Hedge Shares from Dealer at the Relevant Price on such Exchange Business Days, and in the amounts, requested by Dealer.

Right to Extend. Dealer may postpone or add, in whole or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by Dealer, with respect to some or all of the Options hereunder, if Dealer reasonably determines, in its commercially reasonable judgment and, in respect of clause (ii) below, based on the advice of counsel, that such action is reasonably necessary or advisable (i) to preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions (but only if there is a material decrease in liquidity relative to Dealer’s expectations on the Trade Date) or (ii) to enable Dealer to effect transactions in Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were the Issuer or an affiliated purchaser of the Issuer, be in compliance with applicable legal or regulatory requirements, requirements of self-regulatory organizations with jurisdiction over Dealer or its affiliates, or related policies and procedures adopted in good faith by Dealer (so long as such policies and procedures would generally be applicable to counterparties similar to Counterparty and transactions similar to the Transaction); provided that no such Valid Day or other date of valuation, payment or delivery may be postponed or added more than 80 Valid Days after the original Valid Day or other date of valuation, payment or delivery, as the case may be.
