	Re:	  	    [Base][Additional] Call Option Transaction

 The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and
conditions of the call option transaction entered into between [            ] (“Dealer”) and Twitter, Inc. (“Counterparty”) as of the Trade Date specified
below (the “Transaction”). This letter agreement constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below. This Confirmation shall replace any previous agreements and serve as the final
documentation for the Transaction. 
 The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the
“Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. In the event of any inconsistency between the Equity Definitions and
this Confirmation, this Confirmation shall govern. Certain terms defined herein are based on terms that are defined in the Offering Memorandum dated [            ], 2014 (the
“Offering Memorandum”) relating to the [            ] due 20[    ] (as originally issued by Counterparty, the “Convertible Notes” and
each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty in an aggregate initial principal amount of USD [            ] (as
increased by up to an aggregate principal amount of USD [            ] if and to the extent that the Initial Purchasers (as defined herein) exercise their over-allotment option to purchase
additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture [to be]1 dated
[            ], 2014 between Counterparty and [            ], as trustee (the “Indenture”). In the event of any
inconsistency between the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions
set forth in the Indenture that are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum. If any such definitions in
the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. The parties further acknowledge
that the Indenture section numbers used herein are based on the [draft of the Indenture last reviewed by Dealer and Counterparty as of the date of this Confirmation, and if any such section numbers are changed in the Indenture as executed, the
parties will amend this Confirmation in good faith to preserve the intent of the parties]2[Indenture as executed]3. Subject to the foregoing,
references to the Indenture herein are references to the Indenture as in effect on the date of its execution, and if the Indenture is amended or supplemented following such date, any such amendment or supplement (other than any amendment or
supplement pursuant to Section 10.01(k) of the Indenture that, as reasonably determined by the Calculation Agent, conforms the Indenture to the description of the Convertible Notes in the Offering Memorandum) will be disregarded for purposes of
this Confirmation unless the parties agree otherwise in writing. 
 Each party is hereby advised, and each such party acknowledges, that the
other party has engaged in, or refrained from engaging in, substantial financial transactions and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this Confirmation relates on the terms and
conditions set forth below.

	2 	Include in the Base Call Option Confirmation. Include in the Additional Call Option Confirmation if it is executed before closing of the base deal. 


	3 	Include in the Additional Call Option Confirmation, but only if the Additional Call Option Confirmation is executed after closing of the base deal. 









	1.	This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall be subject to an agreement (the
“Agreement”) in the form of the 2002 ISDA Master Agreement (Multicurrency—Cross Border) as if Dealer and Counterparty had executed an agreement in such form on the date hereof (but without any Schedule except for (i) the
election of US Dollars (“USD”) as the Termination Currency, (ii) the replacement of the word “third” in the last line of Section 5(a)(i) of the Agreement with the word “first”[, (iii) the election
of an executed guarantee of [—] (“Guarantor”) dated as of the Trade Date in substantially the form attached hereto as Annex A as a Credit Support Document, (iv) the
designation of Guarantor as Credit Support Provider in relation to Dealer]4 and (v) (a) the election that the “Cross Default” provisions of Section 5(a)(vi) of the
Agreement shall apply to Dealer with a “Threshold Amount” of three percent of the shareholders’ equity of [Name of Dealer’s Parent], (b) the phrase “or becoming capable at such time of being declared” shall be
deleted from clause (1) of such Section 5(a)(vi), and (c) the following language shall be added to the end thereof: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of
Default if (x) the default was caused solely by error or omission of an administrative or operational nature; (y) funds were available to enable the party to make the payment when due; and (z) the payment is made within two Local
Business Days of such party’s receipt of written notice of its failure to pay.”). In the event of any inconsistency between provisions of the Agreement and this Confirmation, this Confirmation will prevail for the purpose of the
Transaction to which this Confirmation relates. For the avoidance of doubt, except to the extent of an express conflict, the application of any provision of this Confirmation, the Agreement or the Equity Definitions shall not be construed to exclude
or limit the application of any other provision of this Confirmation, the Agreement or the Equity Definitions. The Transaction hereunder shall be the sole Transaction under the Agreement. If there exists any ISDA Master Agreement between Dealer and
Counterparty or any confirmation or other agreement between Dealer and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Dealer and Counterparty, then notwithstanding anything to the contrary in such ISDA Master
Agreement, such confirmation or agreement or any other agreement to which Dealer and Counterparty are parties, the Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

[            ], 2014 between Dealer and Counterparty (the “Base Call Option Confirmation”),]10 shall be deemed to be
automatically exercised; provided that such Options shall be exercised or deemed exercised only if Counterparty or the Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) on
behalf of Counterparty has provided a Notice of Exercise to Dealer in accordance with “Notice of Exercise” below. If the Trustee (or any other such agent) on behalf of Counterparty provides any Notice of Exercise to Dealer, Dealer shall be

and reasonable expenses incurred by Dealer in connection with its (or any of its affiliates’) hedging activities hereunder (including the unwinding of any hedge position) as a result of
Dealer not having received such notice on or prior to the Exercise Notice Deadline and Dealer’s obligation to make any payment or delivery in respect of such exercise shall not be extinguished; and provided further that in respect of any
Options relating to Convertible Notes with a Conversion Date occurring on or after the Free Convertibility Date, (A) such notice may be given on or prior to the second Scheduled Valid Day immediately preceding the Expiration Date and need only
specify the information required in clause (i) above, and (B) if the Relevant Settlement Method for such Options is not Net Share Settlement, Dealer shall have received a separate notice (the “Notice of Final Settlement

 Settlement Terms.  

 

	               Settlement Method: 
	For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement Method, but
only if Counterparty or Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) shall have notified Dealer of the Relevant Settlement Method in the Notice of Exercise or Notice of Final
Settlement Method, as applicable, for such Option. If the Trustee (or any other such agent) on behalf of Counterparty provides any such notice, Dealer shall be entitled to rely on the accuracy of such notice without any independent investigation,
and the contents of such notice shall be binding on Counterparty. Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act (as defined below) and the
rules and regulations thereunder, in respect of any election of a settlement method with respect to the Convertible Notes. 

  

	               Relevant Settlement Method: 
	In respect of any Option: 

  

	 	(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 13.02(a)(iv)(A) of the Indenture (together with cash
in lieu of fractional Shares) (such settlement method, “Settlement in Shares”) or (B) in a combination of cash and Shares pursuant to Section 13.02(a)(iv)(C) of the Indenture with a Specified Cash Amount equal to or less
than USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement; 

  

	 	(ii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note in a combination of cash and Shares pursuant to Section 13.02(a)(iv)(C) of the Indenture with a
Specified Cash Amount greater than USD 1,000, then the Relevant Settlement Method for such Option shall be Combination Settlement; and 

  

	 	(iii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note entirely in cash pursuant to Section 13.02(a)(iv)(B) of the Indenture (such settlement method,
“Settlement in Cash”), then the Relevant Settlement Method for such Option shall be Cash Settlement. 

  

	               Net Share Settlement: 
	 If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a
number of Shares (the “Net Share Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by
(b) the Relevant Price on such 



  
 6 









	 	 
Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Net Share Settlement Amount for any Option
exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for such Option. 



 

	 	Dealer will deliver cash in lieu of any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.


  

	               Combination Settlement: 
	If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option: 


 

			
		  	 (i)     cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid
Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the
Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in
zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and

		
		  	 (ii)    Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day
during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the
Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the
calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;


  

	 	provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable
Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option. If any reduction is made to the delivery obligation hereunder as a result of the foregoing, such reduction shall first be made to any Combination
Settlement Share Amount. 


  
 7 









	 	Dealer will deliver cash in lieu of any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.


  

	               Cash Settlement: 
	If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an amount of
cash (the “Cash Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid Day, divided by (ii) the number of Valid
Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount for any Option exceed the Applicable Limit for such Option. 


 

	               Daily Option Value: 
	For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) (a) the Relevant Price on such Valid Day less (b) the Strike Price on such Valid Day; provided that if the
calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero. 


 

	               Make-Whole Adjustment: 
	Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes for which additional Shares will be added to the “Conversion Rate” (as defined in the Indenture) as
determined pursuant to Section 13.03 of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the number of such Additional Shares as determined with reference to the
adjustment set forth in such Section 13.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any) deliverable by Dealer to Counterparty per exercised Option and (b) the
Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the amount per Option, as determined by the Calculation Agent, that would be
payable by Dealer under Section 6 of the Agreement if (x) the relevant Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction was the sole Affected Transaction
and Counterparty was the sole Affected Party and (y) Section 13.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess, with such reduction first being
made to any Shares deliverable hereunder. 

  

	               Applicable Limit: 
	 For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the sum of (A) the amount of cash, if any, payable to the




  
 8 









	 	 
Holder of the related Convertible Note upon conversion of such Convertible Note, as determined with reference to Section 13.02(a) of the Indenture, and (B) the number of Shares, if any,
deliverable to the Holder of the related Convertible Note upon conversion of such Convertible Note, as determined with reference to Section 13.02(a) of the Indenture, multiplied by the Applicable Limit Price on the Settlement Date for
such Option, over (ii) USD 1,000.

of the Exchange to the Scheduled Closing Time of the Exchange on such Valid Day (or if such volume-weighted average price is unavailable at such time, the market value of one Share on such Valid Day, as determined by the Calculation Agent in good
faith and in a commercially reasonable manner using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after hours trading or any other trading outside of the regular trading session trading
hours. 

  

	               Settlement Averaging Period: 
	For any Option:

	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9 and 9.11 of the Equity Definitions will be applicable, as if Physical Settlement applied to the Transaction.

through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)). With respect to
any such certificated Shares (as described in clause (ii) above), the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by deleting the remainder of the provision after the word
“encumbrance” in the fourth line thereof.

Price”, “Daily VWAP,” “Daily Conversion Value” or “Daily Settlement Amount” (each as defined in the Indenture). For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder,

(y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Indenture of the type referred to in the
immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 13.04(c) of the Indenture or the fourth sentence of Section 13.04(d) of the Indenture). 



 

	               Method of Adjustment: 
	Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions (and, for the avoidance of doubt, in lieu of any adjustments pursuant to such Section), upon any Potential Adjustment Event, the
Calculation Agent shall make a corresponding adjustment in respect of any adjustment to the Convertible Notes under the Indenture to any one or more of the Strike Price, Number of Options, Option Entitlement, the composition of the Shares and any
other variable relevant to the exercise, settlement or payment for the Transaction, as determined by reference to the Dilution Adjustment Provisions, to the extent an adjustment is required under the Indenture; provided that, notwithstanding
the foregoing, if the Calculation Agent acting in good faith and in a commercially reasonably manner disagrees with any adjustment pursuant to the terms of the Indenture that is the basis of any adjustment hereunder and that involves an exercise of
discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 13.05 of the Indenture or any supplemental indenture entered into pursuant to Section 10.01(j) 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 the adjustment to be made to any one or more of the composition of the Shares,
Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner; and provided further that, notwithstanding the foregoing, if
any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment is made 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 related Conversion Date, then the Calculation Agent shall make an adjustment, consistent with the methodology set forth in the Indenture, to the terms hereof in order to account for such Potential Adjustment Event. 


 

	               Dilution Adjustment Provisions: 
	Section 13.04(a), (b), (c), (d) and (e) and Section 13.05 of the Indenture.

 Extraordinary Events applicable to the Transaction: 

 

	               Merger Events: 
	Applicable; provided that notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in the definition of “Merger Event” in
Section 13.07(a) of the Indenture. 

  

	               Tender Offers: 
	Applicable; provided that notwithstanding Section 12.1(d) of the Equity Definitions, a “Tender Offer” means the occurrence of any event or condition set forth in Section 13.04(e) of the Indenture. 


              Consequence of Merger Events 

	                 / Tender Offers: 
	Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence of a Merger Event or a Tender Offer, the Calculation Agent shall make an adjustment in respect of any adjustment required to be made under the
Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction (as determined
by the Calculation Agent acting in good faith and in a commercially reasonable manner by reference to the relevant provisions of the Indenture); provided that (x) such adjustment shall be made without regard to any adjustment to the
Conversion Rate pursuant to any Excluded Provision and (y) the Calculation Agent may limit or alter any such adjustment referenced in this paragraph so that the fair value of the Transaction to Dealer is not reduced as a result of such
adjustment; and provided further that, notwithstanding the foregoing, if the Calculation Agent in good faith disagrees with any adjustment pursuant to the terms of the Indenture that is the basis of any adjustment hereunder and that involves
an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 10.01(j) of the Indenture), then the Calculation Agent acting in good faith and in a commercially reasonable manner will
determine the adjustment to be made to any one or more of the nature of the Shares, Strike Price, Number of Options, Option Entitlement, Regular Dividend and any other variable relevant to the exercise, settlement or payment for the Transaction in a
commercially reasonable manner; and provided further that if, with respect to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or
person that is not a corporation or is not organized under the laws of the United States, any State thereof or the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender Offer, will not be a
corporation or will not be the Issuer following such Merger Event or Tender Offer, then Dealer, in its commercially reasonable discretion, may elect for Cancellation and Payment (Calculation Agent Determination) to apply.

	                 Delisting: 
	Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity 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); if the Shares are 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), such exchange or quotation system shall thereafter be deemed to be the Exchange.

	8.	Representations, Warranties and Covenants. 

  

	 	I.	Representations , Warranties and Covenants of Counterparty. Counterparty hereby represents and warrants to Dealer that each of the representations and warranties of Counterparty set forth in Section 1 of the
Purchase Agreement (the “Purchase Agreement”), dated as of September 11, 2014, among Counterparty and Goldman, Sachs & Co. and Morgan Stanley & Co. LLC as representatives of the several Purchasers named in
Schedule I thereto (the “Initial Purchasers”), is true and correct and is hereby deemed to be repeated to Dealer as if set forth herein. Counterparty hereby further represents and warrants to Dealer on the date hereof and on and as
of the Premium Payment Date that: 

  

	 	(a)	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. 

  

	 	(b)	Each of Counterparty and its affiliates is not, on the date hereof, aware of any material non-public information with respect to Counterparty or the Shares. All reports and other documents filed by Counterparty with the
Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), when considered as a whole (with the more recent such reports and documents deemed to amend inconsistent statements
contained in any earlier such reports and documents), do not contain any untrue statement of a material fact or any omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the
circumstances in which they were made, not misleading. 

  

	 	(c)	No U.S. state or local 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) as a result of Dealer or its affiliates owning or holding (however defined) Shares, other than any regulation that Dealer would be subject to as a result of its being a regulated entity under various
applicable laws, including U.S. securities laws and FINRA. 

  

	 	(d)	Counterparty represents and warrants that it has received, read and understands the OTC Options Risk Disclosure Statement and a copy of the most recent disclosure pamphlet prepared by The Options Clearing Corporation
entitled “Characteristics and Risks of Standardized Options”. 

  

	 	(e)	Counterparty (i) is an “institutional account” as defined in FINRA Rule 4512(c); (ii) is capable of evaluating investment risks independently, both in general and with regard to all transactions and
investment strategies involving a security or securities, and will exercise independent judgment in evaluating the recommendations of Dealer or its associated persons; and (iii) will notify Dealer if any of the statements contained in clause
(i) or (ii) of this Section 8(f) ceases to be true. 

  

	 	(f)	Without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that neither Dealer nor any of its affiliates is making any representations or warranties or taking any position
or expressing any view with respect to the treatment of the Transaction under any accounting standards including ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, or ASC Topic 480, Distinguishing Liabilities
from Equity and ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity (or any successor issue statements). 


  
 15 









	 	(g)	Counterparty is not engaged in an “issuer tender offer” as such term is defined in Rule 13e-4 under the Exchange Act with respect to any Shares or any security convertible into or exchangeable or exercisable
for any Shares nor is it aware of any third party tender offer with respect to any such securities within the meaning of Rule 13e-1 under the Exchange Act. 

  

	 	(h)	Counterparty is not entering into this Confirmation to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for Shares) or to manipulate the price of the Shares (or
any security convertible into or exchangeable for Shares) or in violation of the Exchange Act. 

  

	 	(i)	On each of the Trade Date and the Premium Payment Date, Counterparty is not “insolvent” (as such term is defined under 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 the Number of Shares in compliance with the laws of the jurisdiction of Counterparty’s incorporation. 


 

	 	(j)	Counterparty understands that notwithstanding any other relationship between Counterparty and Dealer and its affiliates, in connection with this Transaction and any other over-the-counter derivative transactions between
Counterparty and Dealer or its affiliates, Dealer or its affiliate is acting as principal and is not a fiduciary or advisor in respect of any such transaction, including any entry, exercise, amendment, unwind or termination thereof.


  

	 	II.	Representations , Warranties and Covenants of Counterparty and Dealer. Counterparty and Dealer hereby represent and warrant to Dealer and Counterparty, respectively, on the date hereof and on and as of the
Premium Payment Date that: 

  

	 	(a)	Each 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). 

  

	 	(b)	Each of Dealer and Counterparty acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) thereof. Accordingly,
Counterparty represents and warrants to Dealer that (i) it has the financial ability to bear the economic risk of its investment in the Transaction and is able to bear a total loss of its investment and its investments in and liabilities in
respect of the Transaction, which it understands are not readily marketable, are not disproportionate to its net worth, and it is able to bear any loss in connection with the Transaction, including the loss of its entire investment in the
Transaction, (ii) it is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act, (iii) it is entering into the Transaction for its own account and without a view to the
distribution or resale thereof, (iv) the assignment, transfer or other disposition of the Transaction has not been and will not be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state
securities laws, and (v) its financial condition is such that it has no need for liquidity with respect to its investment in the Transaction and no need to dispose of any portion thereof to satisfy any existing or contemplated undertaking or
indebtedness and is capable of assessing the merits of and understanding (on its own behalf or through independent professional advice), and understands and accepts, the terms, conditions and risks of the Transaction. 


 

	9.	Other Provisions. 

  

	 	(a)	Opinions. On or prior to the Premium Payment Date, Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to the due incorporation, existence and good standing
of Counterparty in Delaware, the due authorization, execution and delivery of this Confirmation, and, in respect of the execution, delivery and performance of this Confirmation, the absence of any conflict with or breach of any material agreement
required to be filed as an exhibit to Counterparty’s Annual Report on Form 10-K, Counterparty’s certificate of incorporation or Counterparty’s by-laws. 


  
 16 









	 	(b)	Repurchase/Adjustment Notices. Counterparty shall, at least one Exchange Business Day prior to any day on which Counterparty effects any repurchase of Shares or consummates or otherwise engages in any
transaction or event (a “Conversion Rate Adjustment Event”) that could reasonably be expected to lead to an increase in the Conversion Rate (as such term is defined in the Indenture), give Dealer a written notice of such
repurchase or Conversion Rate Adjustment Event (a “Repurchase/Adjustment Notice”) on such day if, following such repurchase or Conversion Rate Adjustment Event, the Notice Percentage would reasonably be expected to be
(i) greater than 4.5% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase/Adjustment Notice (or, in the case of the first such Repurchase/Adjustment Notice, greater by 0.5% than the Notice
Percentage as of the date hereof); provided that Counterparty shall not deliver any material non-public information to any employee of Dealer unless that employee has been identified to Counterparty as being on the “private side”.
The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the sum of (a) the product of the Number of Options and the Option Entitlement and (b) the number of Shares
underlying any other similar call option transaction sold by Dealer to Counterparty and the denominator of which is the number of Shares outstanding on such day. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and
their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging activities
as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with
respect to the Transaction), claims, damages, judgments, liabilities, expenses and fees (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to
provide Dealer with a Repurchase/Adjustment Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred
in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand
shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase/Adjustment Notice in accordance with this paragraph, such Indemnified Person shall promptly notify
Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such
proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent,
but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not,
without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or expects to be a party and indemnity
could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably
satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages, liabilities, expenses or fees referred to therein, then
Counterparty, in lieu of indemnifying such Indemnified Person hereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages, liabilities, expenses or fees. The remedies provided for
in this paragraph (b) are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain
operative and in full force and effect regardless of the termination of the Transaction. 


  
 17 









	 	(c)	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 Trade Date, engage in any such distribution.


  

	 	(d)	Transfer or Assignment. 

  

	 	(i)	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: 


 

	 	(A)	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(m) or 9(s) of this Confirmation;


  

	 	(B)	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); 


 

	 	(C)	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 documentation and delivery of legal opinions with respect to securities laws and other matters by
such third party and Counterparty, as are requested and reasonably satisfactory to Dealer; 

  

	 	(D)	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 except to the extent that the greater amount is due to a Change in Tax Law after the date of such transfer or assignment; 


 

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

  

	 	(F)	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 

  

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


 

	 	(ii)	 Dealer may, without Counterparty’s consent, transfer or assign (a “Transfer”) all or any part of its rights or obligations under
the Transaction (A) to any affiliate of Dealer (1) that has a rating for its long term, unsecured and unsubordinated indebtedness that is equal to or better than Dealer’s credit rating at the time of such Transfer, or (2) whose
obligations 



  
 18 









	 	
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 [Name of Dealer parent], or (B) to any
other third party with a rating for its long term, unsecured and unsubordinated indebtedness equal to or better than the lesser of (1) the credit rating of Dealer at the time of the Transfer and (2) BBB+ by Standard and Poor’s Rating
Group, Inc. or its successor (“S&P”), or Baa1 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 either (x) the transferee in any such Transfer is a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or
(y) the Transfer does not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code; and provided further that Dealer shall provide notice to Counterparty following any such Transfer. If at any time
at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A),
(B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and
within a time period reasonably acceptable to Dealer such that (after giving effect to such transfer or assignment and any resulting change in Dealer’s commercially reasonable Hedge Positions) no Excess Ownership Position exists, then Dealer
may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that (after giving effect to such transfer or assignment and any resulting change in
Dealer’s commercially reasonable Hedge Positions) following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment
shall be made pursuant to Section 6 of the Agreement as if (1) 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 number of Options
underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of
Section 9(l) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). 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 Dealer and each person subject to aggregation of Shares with Dealer and each “group” of which Dealer is a member or may be deemed a member, in each case under
Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder, directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and
(B) the denominator of which is the number of Shares outstanding. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of
the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The
“Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule,
regulation, regulatory order or organizational documents or contracts of Counterparty 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 under any Applicable Restriction, as determined by Dealer in its commercially reasonable discretion. The “Applicable Share Limit” means a number of Shares
equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse
effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its commercially reasonable discretion, minus (B) 1% of the number of Shares outstanding. 


  
 19 









	 	(iii)	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. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance. 


 

	 	(e)	Staggered Settlement. Notwithstanding anything to the contrary herein, if upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to
Dealer’s hedging activities hereunder that would be customarily applicable to transactions of this type by Dealer, Dealer may, by prior notice to Counterparty, satisfy its obligation to deliver any Shares or other securities on any date due (an
“Original Delivery Date”) by making separate deliveries of Shares or such securities, as the case may be, at more than one time on or prior to such Original Delivery Date, so long as the aggregate number of Shares and other
securities so delivered on or prior to such Original Delivery Date is equal to the number that, but for this provision, would have been deliverable on such Original Delivery Date. 


 

	 	(f)	[Reserved.] 

  

	 	(g)	[Conduct Rules. Each party acknowledges and agrees to be bound by the Conduct Rules of the Financial Industry Regulatory Authority, Inc. applicable to transactions in options, and further agrees not to
violate the position and exercise limits set forth therein.]11 

  

	 	[Agency	language, if necessary] 

  

	 	(h)	[Reserved.] 

  

	 	(i)	Additional Termination Events.  

  

	 	(i)	Notwithstanding anything to the contrary in this Confirmation if an event of default with respect to Counterparty occurs pursuant to the terms of the Convertible Notes as set forth in Section 6.01 of 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. 


 

	 	(ii)	Promptly following any repurchase and cancellation of Convertible Notes, including without limitation pursuant to Article 14 of the Indenture in connection with a “Fundamental Change” (as defined in the
Indenture), Counterparty shall notify Dealer in writing of such repurchase and cancellation and the number of Convertible Notes so repurchased and cancelled (any such notice, a “Repurchase Notice”). Notwithstanding anything to the
contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repurchase Notice, within the applicable time period set forth in the preceding sentence, and (y) a written representation and warranty by Counterparty that,
as of the date of such Repurchase Notice, Counterparty is not in possession of any material non-public information regarding Counterparty or the Shares, shall constitute an Additional Termination Event as provided in this paragraph. Upon receipt of
any such Repurchase Notice and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repurchase Notice 


 
  

	11 	 To be included for broker-dealer.

(which in no event shall be earlier than the related settlement date for such Convertible Notes) as an Early Termination Date with respect to the portion of this Transaction corresponding to a
number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repurchase Notice [minus the number of “Repurchase Options” (as defined in the Base
Call Option Confirmation), if any, that relate to such Convertible Notes] and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of
Repurchase Options. Any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms
identical to this Transaction and a Number of Options equal to the number of Repurchase Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the
Transaction were the sole Affected Transaction. 

  

	 	(iii)	Notwithstanding anything to the contrary in the Equity Definitions, if, as a result of an Extraordinary Event, the Transaction would be cancelled or terminated (whether in whole or in part) pursuant to Article 12 of the
Equity Definitions, an Additional Termination Event (with the Transaction (or portion thereof) being the Affected Transaction, Counterparty being the sole Affected Party and Dealer being the party entitled to designate an Early Termination Date
pursuant to Section 6(h) of the Agreement) shall be deemed to occur, and, in lieu of Sections 12.7, 12.8 and 12.9 of the Equity Definitions, Section 6 of the Agreement shall apply to such Affected Transaction. 


 

	 	(j)	Amendments to Equity Definitions and Agreement.  

  

	 	(i)	Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and
(2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master
Agreement with respect to that Issuer.” 

  

	 	(ii)	Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party”
with “notice to Counterparty” in the first sentence of such section. 

  

	 	(k)	No 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. 

  

	 	(l)	Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If in respect of the Transaction, an amount is payable by Dealer to Counterparty pursuant to
Section 6(d)(ii) of the Agreement (any such amount, a “Payment Obligation”), 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 Merger Date, the Tender Offer Date, the Announcement Date (in the case of Nationalization, Insolvency or
Delisting), the 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(c) as of the date of such
election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 6(d)(ii) of the Agreement shall apply. 


 

	
                       
   Share Termination Alternative: 
	 If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment
Obligation would 



  
 21 









	 	 
otherwise be due pursuant to Section 6(d)(ii) and 6(e) of the Agreement (the “Share Termination Payment Date”), in satisfaction of such Payment Obligation in the manner
reasonably requested by Counterparty free of payment. 


  

	               Share Termination Delivery Property:

	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the Share Termination Delivery Property by
replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price. 


 

	               Share Termination Unit Price: 
	The value of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the
Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery
Property, to the extent doing so results in a commercially reasonable Share Termination Unit Price. 

  

	               Share Termination Delivery Unit:

	One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “Exchange
Property”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities)
in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent. 

  

	               Failure to Deliver: 
	Applicable 

  

	               Other applicable provisions: 
	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions will be applicable as if Physical Settlement applied to the Transaction and the provisions set forth
opposite the caption “Representation and Agreement” in Section 2 will be applicable. 


  
 22 









	 	(m)	Arbitration.  

  

	 	(i)	All parties to this Confirmation are giving up the right to sue each other in court, including the right to a trial by jury, except as provided by the rules of the arbitration forum in which a claim is filed.


  

	 	(ii)	Arbitration awards are generally final and binding; a party’s ability to have a court reverse or modify an arbitration award is very limited. 


 

	 	(iii)	The ability of the parties to obtain documents, witness statements and other discovery is generally more limited in arbitration than in court proceedings. 


 

	 	(iv)	The arbitrators do not have to explain the reason(s) for their award. 

  

	 	(v)	The panel of arbitrators will typically include a minority of arbitrators who were or are affiliated with the securities industry, unless Counterparty is a member of the organization sponsoring the arbitration
facility, in which case all arbitrators may be affiliated with the securities industry. 

  

	 	(vi)	The rules of some arbitration forums may impose time limits for bringing a claim in arbitration. In some cases, a claim that is ineligible for arbitration may be brought in court. 


 

	 	(vii)	The rules of the arbitration forum in which the claim is filed, and any amendments thereto, shall be incorporated into this Confirmation. 


 

	 	(viii)	Counterparty agrees that any and all controversies that may arise between Counterparty and Dealer, including, but not limited to, those arising out of or relating to the Agreement or the Transaction hereunder, shall
be determined by arbitration conducted before FINRA Dispute Resolution (“FINRA-DR”), or, if the FINRA-DR declines to hear the matter, before the American Arbitration Association, in accordance with their arbitration rules then in force.
The award of the arbitrator shall be final, and judgment upon the award rendered may be entered in any court, state or federal, having jurisdiction. 

  

	 	(ix)	No person shall bring a putative or certified class action to arbitration, nor seek to enforce any pre-dispute arbitration agreement against any person who has initiated in court a putative class action or who is a
member of a putative class who has not opted out of the class with respect to any claims encompassed by the putative class action until: (i) the class certification is denied; (ii) the class is decertified; or (iii) Counterparty is
excluded from the class by the court. 

  

	 	(x)	Such forbearance to enforce an agreement to arbitrate shall not constitute a waiver of any rights under this Confirmation except to the extent stated herein. 


 

	 	(n)	 Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, based on the advice of counsel, the
Shares (the “Hedge Shares”) acquired by Dealer for the purpose of effecting a commercially reasonable hedge of its obligations pursuant to the Transaction cannot be sold in the U.S. public market by Dealer without registration under
the Securities Act, Counterparty shall, at its election: (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 to cover the resale
of such Hedge Shares and (A) enter into a customary agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering, (B) provide
accountant’s “comfort” letters in customary form for registered offerings of equity securities of companies of comparable size, maturity and line of business, (C) provide disclosure opinions of nationally recognized outside
counsel to Counterparty reasonably acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered secondary offerings of equity securities and (E) afford Dealer a reasonable
opportunity to conduct a “due diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity 



  
 23 









	 	
securities; provided that if Counterparty elects clause (i) above but the items referred to therein are not completed in a timely manner, or if Dealer, in its 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 Section 9(m)
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 companies of comparable size, maturity and line of business, in form and substance commercially reasonably satisfactory to Dealer, including customary representations, covenants, blue sky and other
governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Hedge Shares from Dealer), and obligations to use commercially reasonable efforts to obtain opinions and certificates
and such other documentation as is customary for private placement agreements for private placements of equity securities of companies comparable in size, maturity and line of business, all commercially reasonably acceptable 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 compensate Dealer for any 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. This Section 9(m) shall survive the termination, expiration
or early unwind of the Transaction. 

  

	 	(o)	Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all
persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax
structure. 

  

	 	(p)	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 discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder
in light of existing liquidity conditions in the cash market, the stock loan market or other relevant market or to enable Dealer to effect purchases of Shares in connection with its commercially reasonable hedging, hedge unwind or settlement
activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable
to Dealer; provided that in no event shall Dealer have the right to so postpone or add any Valid Day(s) or any such other date beyond the 50th Valid Day immediately following the last Valid Day of
the relevant Settlement Averaging Period (determined without regard to this Section 9(p)). 

  

	 	(q)	Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior to the
claims of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by
Counterparty of its obligations and agreements with respect to the Transaction other than during any such bankruptcy proceedings; provided that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any
transactions other than the Transaction. 

  

	 	(r)	Securities Contract. The parties hereto intend for (i) the Transaction to be a “securities contract” as defined in the Bankruptcy Code, and the parties hereto to be entitled to the
protections afforded by, among other Sections, Sections 362(b)(6), 546(e), and 555 of the Bankruptcy Code, (ii) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default
under the Agreement with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to constitute a
“margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code. 


  
 24 









	 	(s)	Notice of Certain Other Events. Counterparty covenants and agrees that: 

  

	 	(i)	promptly following the public announcement of the results of any election by the holders of Shares with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written
notice of (a) the weighted average of the types and amounts of consideration received by holders of Shares that affirmatively make such an election or (b) if no holders of Shares affirmatively make such an election, the types and amounts
of consideration actually received by the holders of Shares (the date of such notification, the “Consideration Notification Date”); provided that in no event shall the Consideration Notification Date be later than the date on
which such Merger Event is consummated; and 

  

	 	(ii)	promptly following any adjustment to the terms of the Convertible Notes as set forth in the Indenture in connection with any Potential Adjustment Event, Merger Event or Tender Offer, Counterparty shall give Dealer
written notice of the details of such adjustment. 

  

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


 

	 	(u)	Agreements and Acknowledgements Regarding Hedging. Counterparty understands, acknowledges and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or
sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be
active in the market for Shares other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of
Issuer 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 Relevant Prices; and (D) any market activities of Dealer and its affiliates with respect to Shares may affect
the market price and volatility of Shares, as well as the Relevant Prices, each in a manner that may be adverse to Counterparty. 

  

	 	(v)	Early Unwind. In the event the sale of the [“Firm Securities”]12[“Option
Securities”]13 (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers for any reason, or Counterparty fails to deliver to Dealer opinions of counsel as required
pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or such later date, the “Early Unwind Date”), the
Transaction shall automatically terminate (the “Early Unwind”) on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be
cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other

	13 	 Insert for Additional Call Option Confirmation. 



  
 25 









	 	
party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date;. Each
of Dealer and Counterparty represents and acknowledges to the other that upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged. 


 

	 	(w)	Tax Matters. For the purpose of Sections 4(a)(i) and (ii) of the Agreement, Counterparty agrees to deliver to Dealer one duly executed and completed United States Internal Revenue Service Form W-9 (or
successor thereto). 

  

	 	(x)	Payment by Counterparty. In the event that, following payment of the Premium, an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an
Event of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement such amount shall be
deemed to be zero. 

  

	 	(y)	Governing Law. THE AGREEMENT, THIS CONFIRMATION AND ALL MATTERS ARISING IN CONNECTION WITH THE AGREEMENT AND THIS CONFIRMATION SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK (WITHOUT REFERENCE TO ITS CHOICE OF LAW DOCTRINE, OTHER THAN TITLE 14 OF THE NEW YORK GENERAL OBLIGATIONS LAW). 

  

	 	(z)	Amendment. This Confirmation and the Agreement may not be modified, amended or supplemented, except in a written instrument signed by Counterparty and Dealer. 


 

	 	(aa)	Counterparts. This Confirmation may be executed in several counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. 



  
 26 








 Counterparty hereby agrees (a) to check this Confirmation carefully and immediately upon
receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form provided by Dealer) correctly sets forth the terms of the agreement between Dealer and Counterparty with
respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and immediately returning an executed copy to
