	Re:	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 HSBC Bank USA, National Association (“Dealer”) and Knowles Corporation (“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. Each party further agrees that this Confirmation
together with the Agreement evidence a complete binding agreement between Counterparty and Dealer as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or
oral communications with respect thereto. 
 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 defined terms used herein are based on terms that are defined in the Offering Memorandum dated April 28, 2016 (the “Offering Memorandum”)
relating to the 3.25% Convertible Senior Notes due 2021 (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 150,000,000 (as increased by an aggregate principal amount of USD 22,500,000 pursuant to the exercise by the Initial Purchaser (as defined herein) of its option to purchase additional
Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture dated May 4, 2016 between Counterparty and U.S. Bank National Association, as trustee (the “Indenture”). In the event of any
inconsistency between the terms defined in 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 which 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 Indenture as executed. 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 (other than any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture
to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 14.07 of the Indenture, subject, in the case of this clause (y), to the second paragraph under “Method of Adjustment” in Section 3),
any such amendment or supplement 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. 







 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 supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Dealer and Counterparty
had executed an agreement in such form (but without any Schedule except for the election of the laws of the State of New York as the governing law (without reference to choice of law doctrine)) on the Trade Date. 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. The parties hereby agree that no transaction other than the Transaction to which this
Confirmation relates shall be governed by the Agreement.

such 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.

Applicable Percentage and (y) the Specified Cash Amount 



  
 5 









			
		
		  	 minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement

		  	 (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.
		
		  	Dealer will pay cash in lieu of delivering 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:

number of Valid Days in the Settlement Averaging Period. 
		
	 Daily Option Value:
	  	For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less 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.

Indenture) as determined pursuant to Section 14.03 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 14.03 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 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess.

hours.
		
	 Settlement Averaging Period:
	  	For any Option and regardless of the Settlement Method applicable to such Option:

or

		
		  	 (ii)    if the related Conversion Date occurs on or following the Free
Convertibility Date, the 20 consecutive Valid Days commencing on, and including, the 22nd Scheduled Valid Day immediately prior to the Expiration Date; provided that if the Notice of
Exercise or Notice of Final Settlement Method, as applicable, for such Option specifies that Settlement in Shares or Low Cash Combination Settlement applies to the related Convertible Note, the Settlement Averaging Period shall be the 40 consecutive

 9 









			
		
	 Method of Adjustment:
	  	Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make an adjustment to any one or more of the Strike Price,
Number of Options and Option Entitlement that corresponds to the adjustment required to be made pursuant to the Indenture.
		
		  	Notwithstanding the foregoing and “Consequences of Merger Events / Tender Offers” below, 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 the adjustment to be made to any one or more of the nature of the Shares (in the
case of a Merger Event), Strike Price, Number of Options and Option Entitlement in a commercially reasonable manner; provided 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 related Conversion Date, 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.

	  	Sections 14.04(a), (b), (c), (d) and (e) and Section 14.05 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 14.04(e) of the

	 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, to the extent an analogous adjustment is required to be made
pursuant to the Indenture, a corresponding adjustment in respect of any such adjustment 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 and Option Entitlement,
subject to the second paragraph under “Method of Adjustment”; provided, however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to any Excluded Provision; 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, then, in either case, Cancellation and Payment
(Calculation Agent Determination) may apply at Dealer’s sole election.
		
	 Nationalization, Insolvency or

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.

thereof.

the Hedging Party, as determined by the Calculation Agent, shall not be deemed a Hedging Disruption). For the avoidance of doubt, the term “equity price risk” shall be deemed to include, but shall not be limited to, stock price and
volatility risk. And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or (B) above must be available on commercially reasonable pricing terms.”; and

	8.	Representations and Warranties of Counterparty. 

 Each of the
representations and warranties of Counterparty set forth in Section 3 of the Purchase Agreement (the “Purchase Agreement”) dated as of April 28, 2016, between Counterparty and J.P. Morgan Securities LLC, as representative
of the initial purchasers party thereto (the “Initial Purchaser”), are true and correct and are 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:  

  
 13 









	 	(a)	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. 

  

	 	(b)	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 the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, or any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or any agreement or instrument
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, or result in the creation of any
lien under, any such agreement or instrument. 

  

	 	(c)	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. 

  

	 	(d)	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. 

  

	 	(e)	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). 

  

	 	(f)	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. 


 

	 	(g)	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) as a result of Dealer or its affiliates owning or holding (however defined) Shares. 


 

	 	(h)	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 $50 million. 


 

	9.	Other Provisions. 

  

	 	(a)	Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to the matters set forth in Sections 8(a) through (c) of this Confirmation. Delivery of such
opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement. 


  
 14 









	 	(b)	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 80.9 million (in the case of the first such notice) or (ii) thereafter more than 6.4 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 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 and
expenses (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 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 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 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 could have been 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 or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable
by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which 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. 


 

	 	(c)	Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (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. 

  

	 	(d)	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. 


  
 15 









	 	(e)	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(o) or 9(t) 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; 

  

	 	(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 reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment. 


 

	 	(ii)	 Dealer may not transfer any of its rights or obligations under the Transaction without the prior written consent
of Counterparty, except that Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (x) 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 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 (y) with Counterparty’s consent (such consent not to be unreasonably withheld or delayed) (i) to
any financial institution or (ii) solely for the purpose of avoiding an Excess Ownership Position, to any other third party. If at any time at which (A) the Section 16 Percentage exceeds 9.0%, (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 



  
 16 









	 	
Options to a third party reasonably acceptable to Counterparty in accordance with the terms hereof on pricing terms reasonably acceptable to Dealer and within a time period reasonably
acceptable to Dealer such that 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
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(m) 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 any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any
“group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to
the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of
Shares outstanding on such day. 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 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 reasonable discretion, minus (B) 1% of the number of Shares outstanding. 

  

	 	(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. 


  
 17 









	 	(f)	Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable
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:


  

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

  

	 	(ii)	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 

  

	 	(iii)	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. 

  

	 	(g)	[Reserved] 

  

	 	(h)	[Reserved] 

  

	 	(i)	[Reserved] 

  

	 	(j)	Additional Termination Events. 

  

	 	(i)	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 that
results in the acceleration of Counterparty’s payment obligations under the Convertible Notes pursuant to the terms 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)	Notwithstanding anything to the contrary in this Confirmation: 

  

	 	(A)	Promptly following any Repayment Event (as defined below) (but, in any event, within five Scheduled Valid Days following settlement thereof), Counterparty may notify Dealer (any such notice, a “Repayment
Notice”) of such Repayment Event and the aggregate principal amount of Convertible Notes subject to such Repayment Event (the “Repayment Convertible Notes”); provided that any “Repayment
Notice” delivered to Dealer pursuant to the Base Call Option Confirmation shall be deemed to be a Repayment Notice pursuant to this Confirmation and the terms of such Repayment Notice shall apply, mutatis mutandis, to this
Confirmation. The receipt by Dealer from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section 9(j)(ii). 


 

	 	(B)	 Upon receipt of any such Repayment Notice, Dealer shall designate an Exchange Business Day following receipt of
such Repayment Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related settlement date for the relevant Repayment Event) as an Early Termination Date with respect to a portion (the
“Repayment Terminated Portion”) of the Transaction consisting of a number of Options (the “Repayment Options”) equal to the lesser of (A) (x) the number of Repayment 




  
 18 









	 	
Convertible Notes in denominations of USD1,000 that are subject to the relevant Repayment Event, minus (y) the number of “Repayment Options” (as defined in the Base Call
Option Confirmation ), if any, that relate to such Convertible Notes (and for the purposes of determining whether any Options under this Confirmation or under the Base Call Option Confirmation shall be treated as Repayment Options hereunder or
under, and as defined in, the Base Call Option Confirmation, the Convertible Notes specified in such Repayment Notice shall be allocated first to the Base Call Option Confirmation until all Options thereunder are exercised or terminated) and
(B) the Number of Options as of the date Dealer designates such Early Termination Date (prior to giving effect to a reduction thereto on such date pursuant to the immediately following sentence). As of any such Early Termination Date, the
Number of Options shall be reduced by the applicable number of Repayment Options. 

  

	 	(C)	Any payment or delivery in respect of such termination of the Repayment Terminated Portion of the Transaction shall be made pursuant to Section 6 of the Agreement as if 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 Repayment Options. Counterparty shall be the sole Affected Party with respect to such Additional Termination Event and the Repayment
Terminated Portion of the Transaction shall be the sole Affected Transaction. “Repayment Event” means that (i) any Convertible Notes are repurchased by Counterparty or any of its subsidiaries, (ii) any Convertible Notes
are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (however described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of
the Convertible Notes (other than upon acceleration following an event of default under the Convertible Notes), or (iv) any Convertible Notes are exchanged by or for the benefit of the “Holders” (as defined in the Indenture) thereof
for any other securities of Counterparty or any of its “Affiliates” (as defined in the Indenture) (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction. For the avoidance of doubt,
conversion of Convertible Notes (whether into cash, Shares, “Reference Property” (as defined in the Indenture) or any combination thereof) pursuant to the terms of the Indenture shall not constitute a Repayment Event.


  

	 	(D)	Counterparty shall cause any Convertible Notes subject to a Repayment Event to be promptly cancelled and no longer outstanding and acknowledges and agrees that, except to the extent provided above in this Section
9(j)(ii), all such Convertible Notes subject to a Repayment Event will be deemed for all purposes under the Transaction to be cancelled and no longer outstanding. 


 

	 	(k)	Amendments to Equity Definitions. 

  

	 	(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. 


  
 19 









	 	(iii)	Section 12.9(b)(vi) of the Equity Definitions is hereby amended by (1) adding the word “or” immediately before subsection “(B)”, (2) deleting the comma at the end of subsection (A),
(3) deleting subsection (C) in its entirety, (4) deleting the word “or” immediately preceding subsection (C) and (5) replacing the words “either party” in the last sentence of such Section with
“Dealer”. 

  

	 	(l)	No Setoff. Each party waives any and all rights it may have to setoff, whether arising under any agreement, applicable law or otherwise. 


 

	 	(m)	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 (A) pursuant to
Section 12.7 or Section 12.9 of the Equity Definitions or (B) pursuant to Section 6(d)(ii) of the Agreement, in each case, as a result of an event or events outside Counterparty’s control (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 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 sole 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) of the Agreement, as the case may be, 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 otherwise be due pursuant
to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable, 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 to Dealer 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 would be commercially reasonable.



  
 20 









			
		
	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 and the provisions set forth opposite the caption “Representation and Agreement” in
Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references
to “Share Termination Delivery Units”. “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.


  

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


 

	 	(o)	Registration. 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 satisfactory to Dealer, substantially in the form of an underwriting
agreement for a registered secondary offering of 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 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. 


  
 21 









	 	(p)	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. 

  

	 	(q)	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, based on the advice of counsel in the case of the immediately following clause (ii), that such action is reasonably necessary or appropriate (i) to preserve
Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or (ii) to enable Dealer to effect transactions in 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 (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 extended more than 40 Valid Days after the final day in the original Settlement Averaging Period or original other date of valuation, payment or delivery, as the case may be.
