	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] (“Dealer”) and Rambus 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 defined terms used herein are based on terms that are defined in the Offering Memorandum dated November 13, 2017 (the “Offering Memorandum”) relating to the
Convertible Senior Notes due 2023 (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 [up to]1 an aggregate principal amount of USD [22,500,000] [if and to the extent
that]2[pursuant to the exercise by]3 the Initial Purchasers (as defined herein)
[exercise]4[of]5 their over-allotment option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein))
pursuant to an Indenture [to be]6 dated November 17, 2017 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 [draft of the Indenture last reviewed by Dealer 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]7[Indenture as executed]8. 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 following such date (other than any amendment pursuant to (x) Section 10.01(m) of
the Indenture that, as reasonably determined by the Calculation Agent in good faith and in a commercially reasonable manner, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) Section 5.13 of
the Indenture), any such amendment will be disregarded for purposes of this Confirmation (other than as provided in Section 9(h)(iii) below) unless the parties agree otherwise in writing.

	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 (i) the election of the laws
of the State of New York as the governing law (without reference to choice of law doctrine)[, (ii) the election of an executed guarantee of

Support Document, (iii) the election of Guarantor as a Credit Support Provider in relation to Dealer]9 and [(ii)][(iv)] the election that the “Cross Default” provisions of
Section 5(a)(vi) of the Agreement shall apply to Dealer, with a “Threshold Amount” of 3% of Dealer’s [ultimate parent’s] shareholders’ equity (provided that (a) the phrase “, or becoming capable at such

relevant party to make the payment when due; and (iii) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay.”)) on the Trade Date. In the event of any inconsistency between

Confirmation relates shall be governed by the Agreement.

		 	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 the Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) on behalf of Counterparty, 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. The parties hereto agree and acknowledge that if the Trustee or any other agent authorized by Counterparty and previously identified to Dealer by

		  	such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period;

Period.

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 product of (1) the Cash
Percentage and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; 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.
		
		  	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.

number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Cash Settlement Amount 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) 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.
		
	Applicable Limit:	  	For any Option, an amount of cash equal to the Applicable Percentage, multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder of the related Convertible Note upon
conversion of such Convertible Note as determined pursuant to Section 5.03(a) of the Indenture and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note as
determined pursuant to Section 5.03(a) of the Indenture, multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

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.

(including, without limitation, pursuant to Section 5.08 of the Indenture, Section 5.13 of the Indenture or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the

“SP0” (as such term is used in Section 5.06(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such
Potential Adjustment Event, then the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the reasonable costs (including, but not limited to,
hedging mismatches and market losses customary for transactions of this type (subject to the requirements set forth under “Hedging Adjustments” below)) and reasonable expenses incurred by Dealer in connection with its reasonable hedging
activities customary for transactions of this type (subject to the requirements set forth under “Hedging Adjustments” below) as a result of such event or condition not having been publicly announced prior to the beginning of such period;
and

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

  
 11

“Hedging Adjustments” below) as a result of such Potential Adjustment Event Change.

	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 5.13 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 5.06(e) of the
Indenture.
			
		 	Consequences 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 a corresponding adjustment in respect of any 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, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction,
subject to the second paragraph under “Method of Adjustment” (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,
however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate determined 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 organized under the laws of the United States, any State thereof or the District of Columbia or will not be the Issuer
following such Merger Event or Tender Offer, then, in either case, Cancellation and Payment (Calculation Agent Determination) may apply in Dealer’s commercially reasonable discretion.
			
		 	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

  
 12 

 
					
		 		  	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.
		
	Additional Disruption Events:	  	
			
		 	Change in Law:	  	Applicable; provided that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the word “Shares” with the phrase “Hedge Positions” in clause (X) thereof,
(ii) inserting the parenthetical “(including, for the avoidance of doubt and without limitation, adoption or promulgation of new regulations authorized or mandated by existing statute)” at the end of clause (A) thereof and
(iii) immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by the Hedging Party on the Trade Date”.
			
		 	Failure to Deliver:	  	Applicable
			
		 	Hedging Disruption:	  	Applicable; provided that:
			
		 		  	 (i)     Section 12.9(a)(v) of the Equity Definitions is hereby
amended by (a) inserting the following words at the end of clause (A) thereof: “in the manner contemplated by the Hedging Party on the Trade Date” and (b) inserting the following two phrases at the end of such
Section:

			
		 		  	 “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

			
		 		  	 (ii)    Section 12.9(b)(iii) of the Equity Definitions is hereby
amended by inserting in the third line thereof, after the words “to terminate the Transaction”, the words “or a portion of the Transaction affected by such Hedging Disruption”.

			
		 	Increased Cost of Hedging:	  	Not Applicable
			
		 	Hedging Party:	  	For all applicable Additional Disruption Events, Dealer. All calculations and determinations by Hedging Party shall be made in good faith and in a commercially reasonable manner. Following any calculation by Hedging Party
hereunder, upon written request by Counterparty, Hedging Party will provide to Counterparty

  
 13 

					
		 		  	by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such
calculation; provided, however, that in no event will Hedging Party be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it.
			
		 	Determining Party:	  	For all applicable Extraordinary Events, Dealer. All calculations and determinations by Determining Party shall be made in good faith and in a commercially reasonable manner. Following any calculation by Determining Party
hereunder, upon written request by Counterparty, Determining Party will provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation

proprietary or confidential models used by it.
			
		 	Non-Reliance:	  	Applicable.
			
		 	Agreements and Acknowledgments Regarding Hedging Activities:	  	Applicable
			
		 	Hedging Adjustments:	  	For the avoidance of doubt, whenever Dealer or the Calculation Agent is permitted to make an adjustment pursuant to the terms of this Confirmation or the Equity Definitions to take into account the effect of an event (other than,
for the avoidance of doubt, any adjustment that is required to be made by reference to the Indenture), the Calculation Agent or Dealer shall make such adjustment by reference to the effect of such event on Dealer assuming that Dealer maintains a
commercially reasonable hedge position.
			
		 	Additional Acknowledgments:	  	Applicable
			
	4.	 	Calculation Agent.	  	Dealer; provided that following the occurrence and during the continuance of an Event of Default of the type described in Section 5(a)(vii) of the Agreement with respect to which Dealer is the sole Defaulting Party,
if the Calculation Agent fails to timely make any calculation, adjustment or determination required to be made by the Calculation Agent hereunder or to perform any obligation of the Calculation Agent hereunder and such failure continues for five
Exchange Business Days following notice to the Calculation Agent by Counterparty of such failure, Counterparty shall have the right to designate a nationally recognized third-party dealer in over-the-counter corporate equity derivatives to act, during the period commencing on the first date the Calculation

  
 14 

 
			
		  	Agent fails to timely make such calculation, adjustment or determination or to perform such obligation, as the case may be, and ending on the earlier of the Early Termination Date with respect to such Event of Default and the
date on which such Event of Default is no longer continuing, as the Calculation Agent.
		
		  	All calculations and determinations by the Calculation Agent shall be made in good faith and in a commercially reasonable manner. Following any calculation by the Calculation Agent hereunder, upon written request by Counterparty,
the Calculation Agent will provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable
detail the basis for such calculation; provided, however, that in no event will Dealer be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it.

	8.	Representations and Warranties of Counterparty. 

  

	 	(a)	Representations and Warranties of Counterparty. Each of the representations and warranties of Counterparty set forth in Section 2 of the Purchase Agreement (the “Purchase Agreement”), dated
as of November 14, 2017, among Counterparty and Barclays Capital Inc., Credit Suisse Securities (USA) LLC and Deutsche Bank Securities Inc., as representatives of the initial purchasers party thereto (the “Initial Purchasers”), 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: 

 

	 	(i)	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. 

  

	 	(ii)	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 (A) the certificate of incorporation or
by-laws (or any equivalent documents) of Counterparty, or (B) any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or (C) 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, except for any such conflicts, breaches, defaults or lien creations in the cases of clause (C) above that would not adversely affect the ability of Counterparty to fulfill its
obligations under this Transaction. 

  
 16 

	 	(iii)	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. 

  

	 	(iv)	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. 

  

	 	(v)	Counterparty is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares.13 

  

	 	(vi)	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 USD50 million. 

 

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

  

	 	(b)	Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended (the
“CEA”), other than a person that is an eligible contract participant under Section 1a(18)(C) of the CEA). The Transaction has been subject to individual negotiation by the parties. The Transaction has not been executed or
traded on a “trading facility” as defined in the CEA. 

  

	 	(c)	Each of Dealer and Counterparty agrees and represents that it is a “qualified institutional buyer” as defined in Rule 144A under the Securities Act, or an “accredited investor” as defined in
Section 2(a)(15)(ii) of the Securities Act. 

  

	 	(d)	Each of Dealer and Counterparty agrees and represents that the assets used in the Transaction (1) are not assets of any “plan” (as such term is defined in Section 4975 of the U.S. Internal Revenue
Code of 1986, as amended (the “Code”)) subject to Section 4975 of the Code or any “employee benefit plan” (as such term is defined in Section 3(3) of the U.S. Employee Retirement Income Security Act of 1974, as
amended (“ERISA”)) subject to Title I of ERISA, and (2) do not constitute “plan assets” within the meaning of Department of Labor Regulation 2510.3-101, 29 CFR Section 2510-3-101. 

  

	 	(e)	Each of Dealer and Counterparty 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. 

  

	9.	Other Provisions. 

  

	 	(a)	Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Premium Payment Date, with respect to 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. 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. 

 
  

	13 	Counterparty/Counterparty’s counsel to confirm no reporting or consent requirements applicable to Dealer’s ownership of Shares. 

  
 17 

	 	(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 [                    ]14 million (in the case of the first such notice) or (ii) thereafter more than
[                    ]15 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 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 

  

	14 	Insert the number of Shares outstanding that would cause Dealer’s current position in the Shares underlying the Transaction (including the number of Shares underlying any additional transaction if the greenshoe is
exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by 0.5%, based on dealer with highest Applicable Percentage. 

	15 	 Insert the number of Shares that, if repurchased, would cause Dealer’s current position in the Shares
underlying the Transaction (including the number of Shares underlying any additional transaction if the greenshoe is exercised in full, and any Shares under pre-existing call option transactions with
Counterparty) to increase by a further 0.5% from the threshold for the first Repurchase Notice, based on dealer with highest Applicable Percentage. 

  
 18 

	 	
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
manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) in violation of the Exchange Act. 

  

	 	(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(m) or 9(r) 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 Code); 

 

	 	(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 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 (such transfer or assignment, a
“Transfer”) all or any part of its rights or obligations under the Transaction (A) to any affiliate of Dealer (1) that has a long-term issuer rating that is equal to or better than Dealer’s credit rating at the time
of such Transfer, 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,

  
 19 

	 	
or (B) to any other third party with a long-term issuer rating equal to or better than the lesser of (1) the credit rating of Dealer at the time of the Transfer and (2) A- by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”), or A3 by Moody’s Investor Service, Inc. (“Moody’s”) or, if either
S&P or Moody’s ceases to rate such third party, 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 shall
be a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or (y) the Transfer will not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code; and provided
further that Dealer shall provide prompt written notice to Counterparty following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (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 Options to a third party 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(k) 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. 

  
 20 

	 	(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 (each, a “Dealer Designated Affiliate”) to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise
to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations; provided that such Dealer Designated Affiliate shall comply with the provisions of the Transaction in the same manner as
Dealer would have been required to comply. Dealer shall be discharged of its obligations to Counterparty under this Confirmation to the extent such Dealer Designated Affiliate fully performs the obligations designated by Dealer to such Dealer
Designated Affiliate under this Section 9(e)(iii). 

  

	 	(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 that would be customarily applicable to transactions of this type by the dealers in this market as determined by the Calculation Agent, 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 (the first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th)
Exchange Business Day following 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)	[Insert agency language for particular Dealer, if applicable.]][Reserved.] 

  

	 	(h)	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 8.01 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)	 Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty, within
the applicable time period set forth under “Notice of Exercise” above, of any Notice of Exercise in respect of Options that relate to Convertible Notes as to which additional Shares would be added to the Conversion Rate pursuant to
Section 5.11 of the Indenture in connection with a “Make-Whole Fundamental Change” (as 

  
 21 

	 	
defined in the Indenture) shall constitute an Additional Termination Event as provided in this Section 9(h)(ii). Upon receipt of any such Notice of Exercise, Dealer shall designate an
Exchange Business Day following such Additional Termination Event (which Exchange Business Day shall in no event be earlier than the related settlement date for such Convertible Notes) as an Early Termination Date with respect to the portion of the
Transaction corresponding to a number of Options (the “Make-Whole Conversion Options”) equal to the lesser of (A) the number of such Options specified in such Notice of Exercise [minus the number of “Make-Whole
Conversion Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes]16 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 Make-Whole Conversion 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 the Transaction and a Number of Options equal to the number of Make-Whole Conversion 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 (and, for the avoidance of doubt, (x) in determining the amount payable pursuant to
Section 6 of the Agreement, the Calculation Agent shall not take into account any adjustments to the Option Entitlement that result from corresponding adjustments to the Conversion Rate pursuant to Section 5.11 of the Indenture and
(y) the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party); provided that the amount of cash deliverable in respect
of such early termination by Dealer to Counterparty shall not be greater than the product of (x) the Applicable Percentage and (y) the excess of (I) (1) the number of Make-Whole Conversion Options, multiplied by (2) the
Conversion Rate (after taking into account any applicable adjustments to the Conversion Rate pursuant to Section 5.11 of the Indenture), multiplied by (3) a price per Share determined by the Calculation Agent in good faith and in a
commercially reasonable manner over (II) the aggregate principal amount of such Convertible Notes, as determined by the Calculation Agent in a commercially reasonable manner. 

 

	 	(iii)	Notwithstanding anything to the contrary in this Confirmation, the occurrence of an Amendment Event 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. “Amendment Event” means that Counterparty amends, modifies, supplements, waives or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal
amount, coupon, maturity, repurchase obligation of Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion rate, conversion rate adjustment provisions, conversion settlement dates or conversion
conditions), or any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend (other than, in each case, any amendment or supplement (x) pursuant to Section 10.01(m) 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 5.13 of the Indenture), in each case, without the consent of
Dealer. 

  

	 	(iv)	Promptly following any repurchase and cancellation of Convertible Notes, including without limitation pursuant to Article 4 of the Indenture in connection with a “Fundamental Change” (as defined in the
Indenture) (a “Convertible Notes Repurchase Event”), Counterparty shall notify Dealer in writing of such repurchase and cancellation and the number of Convertible Notes in USD 1,000 principal amount so repurchased and

  

	16 	 Include in Additional Call Option Confirmation.

  
 22 

	 	
cancelled (any such notice, a “Notes Repurchase Notice”). Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of any Notes
Repurchase Notice shall constitute an Additional Termination Event as provided in this paragraph. 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 its delivery of any Notes Repurchase Notice. Upon receipt of any such Notes Repurchase Notice, Dealer shall promptly designate an Exchange Business Day following
receipt of such Notes Repurchase Notice (which in no event shall be earlier than the related repurchase 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 Notes 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 for the purposes of determining whether any Options under this Confirmation or under the Base Call Option Confirmation will be among the Repurchase Options
hereunder or under, and as defined in, the Base Call Option Confirmation, the Convertible Notes specified in such Notes Repurchase Notice shall be allocated first to the Base Call Option Confirmation until all Options thereunder are exercised or
terminated)]17 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. For avoidance of doubt, in determining the amount payable in respect of such Additional Termination Event pursuant to Section 6 of the Agreement, Dealer shall assume (1) the relevant
Convertible Notes Repurchase Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions of, by or on behalf of Counterparty leading thereto had not occurred, (2) no adjustments to the Conversion Rate have occurred
pursuant to any Excluded Provisions and (3) the Convertible Notes remain outstanding. 

  

	 	(v)	Notwithstanding anything to the contrary in the Equity Definitions, if, as a result of an applicable 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.

  

	 	(i)	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. 

  

 

	17 	Include in the Additional Call Option Confirmation. 

  
 23 

	 	(j)	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. 

  

	 	(k)	Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event)
occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the
consideration to be paid to all holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a
Termination Event in which Counterparty is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in
Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation
Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless
(a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the 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(a)(v) 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 good faith and in a commercially reasonable manner 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.

  
 24 

			
	 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.

  

	 	(l)	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. 

 

	 	(m)	 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 customary form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of equity securities of comparable size of companies of comparable size,
maturity and line of business; 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 

  
 25 

	 	
for private placements of equity securities of comparable size of companies of comparable size, maturity and line of business, in customary form and substance that is commercially reasonable and
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 then-current market price on such Exchange Business Days, and in the amounts and at such time(s),
requested by Dealer. 

  

	 	(n)	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. 

  

	 	(o)	Right to Extend. Dealer may postpone or add, in a commercially reasonable manner, 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 reasonable 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 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 30th Valid Day immediately following the last Valid Day of the relevant Settlement Averaging Period (determined
without regard to this Section 9(o)). 

  

	 	(p)	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; provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the
Transaction. 

  

	 	(q)	Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code (Title
11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 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. 

  

	 	(r)	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 (x) the weighted average of the types and amounts of consideration that holders of Shares have elected to receive upon consummation of such Merger Event or (y) if no holders of Shares affirmatively make such election, the types
and amounts of consideration actually received by 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 

  
 26 

	 	(ii)	(A) Counterparty shall give Dealer commercially reasonable advance (but in no event less than one Exchange Business Day) written notice of the section or sections of the Indenture and, if applicable, the formula
therein, pursuant to which any adjustment will be made to the Convertible Notes in connection with any Potential Adjustment Event, Merger Event or Tender Offer and (B) promptly following any such adjustment, Counterparty shall give Dealer
written notice of the details of such adjustment. 

  

	 	(s)	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 regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend
or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the 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)). 

 

	 	(t)	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. 

  

	 	(u)	Early Unwind. In the event the sale of the [“Underwritten Securities”]18[“Option Securities”]19 (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 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; provided that Counterparty shall purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates
for the purpose of hedging the Transaction and reimburse Dealer for any costs or expenses (including market losses) relating to the unwinding of its hedging activities in connection with the Transaction (including any loss or cost incurred as a
result of its terminating, liquidating, obtaining or reestablishing any hedge or related trading position). The amount of any such reimbursement shall be determined by Dealer in its sole good faith discretion. Dealer shall notify Counterparty of
such amount and Counterparty shall pay such amount in immediately available funds on the Early Unwind Date. Each of Dealer and Counterparty represents and acknowledges to the other that, subject to the proviso included in this Section 9(u),
upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged. 

  

 

	18 	Insert for Base Call Option Confirmation. 

	19 	Insert for Additional Call Option Confirmation. 

  
 27 

	 	(v)	Payment by Counterparty. In the event that, following payment of the Premium, (i) 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, or
(ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero. 

 

	 	(w)	Determinations; Adjustments. All calculations, adjustments and determinations made by Dealer hereunder, whether as Calculation Agent, as Determining Party or following the occurrence of an Early
Termination Date, shall be made in good faith and in a commercially reasonable manner. Following any determination, adjustment or calculation by Dealer hereunder (including, without limitation, in its capacity as Calculation Agent), Dealer will
provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such
calculation; provided, however, that in no event will Dealer be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it. For the avoidance of doubt,
whenever the Calculation Agent or Determining Party (as the case may be) is called upon to make an adjustment pursuant to the terms of this Confirmation or the Equity Definitions (other than any adjustment required to be made by reference to the
terms of the Convertible Notes or the Indenture) to take into account the effect of an event, the Calculation Agent or Determining Party (as the case may be) shall make such adjustment by reference to the effect of such event on the Hedging Party,
assuming that the Hedging Party maintains a commercially reasonable hedge position. 

  

	 	(x)	Additional ISDA Schedule Terms.  

  

	 	1.	Automatic Early Termination. The “Automatic Early Termination” provision of Section 6(a) of the Agreement will not apply to Dealer and will not apply to Counterparty. 

 

	 	2.	Consent to Recording. Each party (i) consents to the monitoring or recording, at any time and from time to time, by the other party of any and all communications between officers or employees of the parties,
(ii) waives any further notice of such monitoring or recording, and (iii) agrees to notify (and, if required by law, obtain the consent of) its officers and employees with respect to such monitoring or recording. Any such recording may be
submitted in evidence to any court or in any Proceeding for the purpose of establishing any matters pertinent to this Transaction. 

  

	 	3.	Severability. In the event any one or more of the provisions contained in this Confirmation or the Agreement shall be held illegal, invalid or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. 

  

	 	(y)	Understanding and Acknowledgement. Counterparty understands and acknowledges that notwithstanding any other relationship between Counterparty and Dealer (and Dealer’s affiliates), in
connection with this Transaction and any other over-the-counter derivative transaction between Counterparty and Dealer or Dealer’s affiliates, Dealer or its
affiliates, as the case may be, is acting as principal and is not a fiduciary or adviser to Counterparty in respect of any such transaction, including any entry into or exercise, amendment, unwind or termination thereof. 

 

	 	(z)	 Withholding Tax imposed on payments to non-US counterparties under
the United States Foreign Account Tax Compliance Act. “Indemnifiable Tax”, as defined in Section 14 of the Agreement, shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471
through 1474 of the Code, any current or future regulations or official interpretations thereof, any 

  
 28 

	 	
agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into
in connection with the implementation of such Sections of the Code (a “FATCA Withholding Tax”). For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required by applicable law for the
purposes of Section 2(d) of the Agreement. 

  

	 	(aa)	HIRE Act. “Indemnifiable Tax”, as defined in Section 14 of the Agreement, shall not include any tax imposed on payments treated as dividends from sources within the United States
under Section 871(m) of the Code or any regulations issued thereunder. For the avoidance of doubt, any such tax imposed under Section 871(m) of the Code is a Tax the deduction or withholding of which is required by applicable law for the
purposes of Section 2(d) of the Agreement.

	Re:	[Base][Additional] Warrants 

 The purpose of this letter agreement (this
“Confirmation”) is to confirm the terms and conditions of the Warrants issued by Rambus Inc. (“Company”) to [Dealer] (“Dealer”) 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. 
 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 Company 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 Company 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 that 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. 
 2.    The Transaction is a Warrant Transaction, which shall be considered a
Share Option Transaction for purposes of the Equity Definitions. The terms of the particular Transaction to which this Confirmation relates are as follows: 

General Terms.

scheduled opening time of the Exchange to the Scheduled Closing Time on such Valuation Date (or if such Bloomberg page is unavailable, the market value of one Share on such Valuation Date, as determined by the Calculation Agent in good faith and in
a commercially reasonable manner based on generally available market data for transactions of this type using, if practicable, a volume-weighted methodology). Notwithstanding the foregoing, if (i) any Expiration Date is a Disrupted Day and
(ii) the Calculation Agent determines that such Expiration Date shall be an Expiration Date for fewer than the Daily Number of Warrants, as described above, then the Settlement Price for the relevant Valuation Date shall be the volume-weighted
average price per Share on such Valuation Date on the Exchange (as determined by the Calculation Agent in good faith and in a commercially reasonable manner based on generally available market data for transactions of this type using a commercially
reasonable volume-weighted methodology) for the portion of such Valuation Date for which the Calculation Agent determines there is no Market Disruption Event.
		
	Settlement Dates:	  	As determined pursuant to Section 9.4 of the Equity Definitions, subject to Section 9(k)(i) hereof; provided that Section 9.4 of the Equity Definitions is hereby amended by (i) inserting the words

be read as references to “Net Share Settled.” “Net Share Settled” in relation to any Warrant means that Net Share Settlement is applicable to that Warrant.
		
	Representation and Agreement:	  	Notwithstanding Section 9.11 of the Equity Definitions, the parties acknowledge that any Shares delivered to Dealer in the event of a Net Share Settlement may be, upon delivery, subject to restrictions and limitations
arising from Company’s status as issuer of the Shares under applicable securities laws.

amended (the “Exchange Act”), Rule 10b5-1 of the Exchange Act or pursuant to forward contracts or accelerated stock repurchase contracts or similar derivatives transactions on customary terms,

adjustments, if any, to any one or more of the Strike Price, the Number of Warrants, the Daily Number of Warrants and the Warrant Entitlement in a commercially reasonable manner. Notwithstanding the foregoing, any cash dividends or cash

Expiration Date, Early Termination Date or other date of cancellation (the “Announcement Event Adjustment Date”) in respect of each Warrant, the Calculation Agent will determine the economic effect of such Announcement Event on the
theoretical value of the Warrant (regardless of whether the Announcement Event actually results in a Merger Event, Tender Offer or Acquisition Transaction, as the case may be (subject to the last sentence of this Section), and taking into account
such factors as the Calculation Agent may determine, including, without limitation, changes in volatility, expected dividends, stock loan rate or liquidity relevant to the Shares or the Transaction whether prior to or after the Announcement Event or
for any period of time, including, without limitation, the period from the Announcement Event to the relevant Announcement Event Adjustment Date). If the Calculation Agent determines that such economic effect on any Warrant is material, then on the
Announcement Event Adjustment Date for such Warrant, the Calculation Agent shall make such adjustment to the Strike Price, the Number of Warrants, the Daily Number of Warrants, the Warrant Entitlement and/or the Expiration Dates, in each case, as
the Calculation Agent determines in good faith and in a commercially reasonable manner appropriate to account for such economic effect, which adjustment shall be effective immediately prior to the exercise, termination or cancellation of such
Warrant, as the case may be; provided that if the Calculation Agent shall make any adjustment to the terms of the Transaction upon the occurrence of a particular “Announcement Event”, then the Calculation Agent shall make an
adjustment to the terms of the Warrant prior to the Expiration Date, any Early Termination Date and/or any other date of cancellation in connection with the abandonment (if applicable) of any such event that gave rise to the original Announcement
Event.

“Shares” in the

  
 8

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

Section:

		
		  	 “For the avoidance of doubt, the term “equity price risk” shall be deemed to include, but shall not

if the Calculation Agent fails to timely make any calculation, adjustment or determination required to be made by the Calculation Agent hereunder or to perform any obligation of the Calculation Agent hereunder and such failure continues for five
Exchange Business Days following notice to the Calculation Agent by Company of such failure, Company shall have the right to designate a nationally recognized third-party dealer in
over-the-counter corporate equity derivatives to act, during the period commencing on the first date the Calculation Agent fails to timely make such calculation,
adjustment or determination or to perform such obligation, as the case may be, and ending on the earlier of the Early Termination Date with respect to such Event of Default and the date on which such Event of Default is no longer continuing, as the

	 	(iii)	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 Company 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. 

  

	 	(iv)	A number of Shares equal to the Maximum Number of Shares (the “Warrant Shares”) have been reserved for issuance by all required corporate action of Company. The Warrant Shares have been duly authorized
and, when delivered against payment therefor (which may include Net Share Settlement in lieu of cash) and otherwise as contemplated by the terms of the Warrants following the exercise of the Warrants in accordance with the terms and conditions of
the Warrants, will be validly issued, fully-paid and non-assessable, and the issuance of the Warrant Shares will not be subject to any preemptive or similar rights. 

  
 13 

	 	(v)	Company 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. 

  

	 	(vi)	Company is not, on the date hereof, in possession of any material non-public information with respect to Company or the

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

  

	 	(b)	Eligible Contract Participants. Each of Dealer and Company agrees and represents that it is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity
Exchange Act, as amended (the “CEA”), other than a person that is an eligible contract participant under Section 1a(18)(C) of the CEA). 

  

	 	(c)	Private Placement Representations. Each of Dealer and Company 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, Dealer represents and warrants to Company 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

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.

  

	 	(d)	ERISA. Each of Dealer and Company agrees that the assets used in the Transaction (1) are not assets of any “plan” (as such term is defined in Section 4975 of the U.S. Internal Revenue
Code of 1986, as amended (the “Code”)) subject to Section 4975 of the Code or any “employee benefit plan” (as such term is defined in Section 3(3) of the U.S. Employee Retirement Income Security Act of 1974, as
amended (“ERISA”)) subject to Title I of ERISA, and (2) do not constitute “plan assets” within the meaning of Department of Labor Regulation 2510.3-101, 29 CFR Section 2510-3-101.

	9.	Other Provisions. 

  

	 	(a)	Opinions. Company shall deliver to Dealer an opinion of counsel, dated as of the Premium Payment Date, with respect to due incorporation, existence and good standing of Company 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
Company’s Annual Report on Form 10-K, Company’s certificate of incorporation or Company’s by-laws. 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. 

  

	 	(b)	Repurchase Notices. Company shall, on any day on which Company 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 on such day, subject to any adjustments provided herein, is (i) less than
[                    ]5 million (in the case of the first such notice) or (ii) thereafter
more than [                    ]6 million less than the number of Shares included in the
immediately preceding Repurchase Notice. Company 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 commercially reasonable 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 actually may become subject to, as a result of Company’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, such Indemnified Person shall promptly notify
Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay
the reasonable fees and expenses of such counsel related to such proceeding. Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for
the plaintiff, Company agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Company shall not, without the prior written consent of the Indemnified Person, effect any settlement
of any pending or threatened proceeding in respect of which any Indemnified Person is 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 Company under such paragraph, 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 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. 

 
  

	5 	Insert the number of Shares outstanding that would cause Dealer’s current position in the Warrants (including the number of Warrants if the greenshoe is exercised in full, and any warrants under pre-existing warrant transactions with Company) to increase by 0.5%, based upon dealer with highest Applicable Percentage. 

	6 	Insert the number of Shares that, if repurchased, would cause Dealer’s current position in the Warrants (including the number of Warrants if the greenshoe is exercised in full, and any warrants under pre-existing warrant transactions with Company) to increase by a further 0.5% from the threshold for the first Repurchase Notice, based upon dealer with highest Applicable Percentage. 

  
 15 

	 	(c)	Regulation M. Company 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 Company, other than a distribution meeting the
requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Company shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution. 

 

	 	(d)	No Manipulation. Company 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 manipulate
the price of the Shares (or any security convertible into or exchangeable for the Shares) in violation of the Exchange Act. 

  

	 	(e)	 Transfer or Assignment. Company may not transfer any of its rights or obligations under the
Transaction without the prior written consent of Dealer. Dealer may, without Company’s consent, transfer or assign (such transfer or assignment, a “Transfer”) all or any part of its rights or obligations under the Transaction
to any third party; provided that, (i) as a result of any such Transfer, Company will not be required to pay the transferee or assignee of such rights or obligations on any payment date an amount under Section 2(d)(i)(4) of the
Agreement greater than the amount, if any, that Company would have been required to pay Dealer in the absence of such Transfer and (ii) upon written request, the transferee or assignee shall provide Company with a complete and accurate U.S.
Internal Revenue Service Form W-9 or W-8 (as applicable) prior to becoming a party to the Transaction; provided further that Dealer shall provide written notice
to Company following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 8.0%, (B) the Warrant 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, acting in good faith, is unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants to a
third party 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 Terminated Portion, 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 Warrants
equal to the number of Warrants underlying the Terminated Portion, (2) Company 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(j) shall apply to any amount that is payable by Company to Dealer pursuant to this sentence as if Company 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 “Warrant 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 Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, 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, 

  
 16 

	 	
rule, regulation, regulatory order or organizational documents or contracts of Company 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. 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 Company, Dealer may designate any of its affiliates
to purchase, sell, receive or deliver such Shares or other securities, or 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 Company to the extent of any such performance. 

  

	 	(f)	Dividends. If at any time during the period from and including the Effective Date, to and including the last Expiration Date, an ex-dividend date for a cash dividend
or cash distribution occurs with respect to the Shares (an “Ex-Dividend Date”), then the Calculation Agent will adjust any of the Strike Price, the Number of Warrants, the Daily Number of
Warrants, the Warrant Entitlement and/or the Expiration Dates, in each case, to preserve the fair value of the Warrants to Dealer after taking into account such cash dividend or cash distribution. 

 

	 	(g)	[Insert agency language for particular Dealer, if applicable.]][Reserved.] 

  

	 	(h)	Additional Provisions.

of any material non-public information regarding the Non-Hedging Party or the Shares and is electing to terminate the Transaction in good faith and not as part of a plan
or scheme to evade compliance with the federal securities laws)” immediately preceding the period at the end of subsection (C) thereof. 

  

	 	(ii)	Notwithstanding anything to the contrary in this Confirmation, upon the occurrence of one of the following events, with respect to the Transaction, (1) Dealer shall have the right to designate such event an
Additional Termination Event and designate an Early Termination Date pursuant to Section 6(b) of the Agreement, (2) Company shall be deemed the sole Affected Party with respect to such Additional Termination Event and (3) the
Transaction, or, at the election of Dealer in its sole discretion, any portion of the Transaction, shall be deemed the sole Affected Transaction; provided that if Dealer so designates an Early Termination Date with respect to a portion of the
Transaction, (a) a payment 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 Warrants equal to the
number of Warrants included in the terminated portion of the Transaction, and (b) for the avoidance of doubt, the Transaction shall remain in full force and effect except that the Number of Warrants shall be reduced by the number of Warrants
included in such terminated portion: 

  

	 	(A)	Any “person” or “group” (other than Company, Company’s directly or indirectly wholly-owned subsidiaries or Company’s or its subsidiaries’ respective employee benefit plans) files a
Schedule 13D or Schedule TO, or any successor schedule, form or report under the Exchange Act, disclosing, or Company otherwise becomes aware, that such person is or has become the “beneficial owner,” directly or indirectly, of shares of
Company’s voting stock representing 50% or more of the total voting power of all outstanding classes of Company’s voting stock or has the power, directly or indirectly, to elect a majority of the members of Company’s board of
directors. 

  
 18 

	 	(B)	The consummation of (1) any recapitalization, reclassification or change of the Shares (other than changes resulting from a subdivision or combination) as a result of which the Shares would be converted into, or
exchanged for, stock, other securities, other property or assets (other than a transaction or event described in clause (2) below); (2) any share exchange, consolidation or merger of Company pursuant to which the Shares will be converted into
or exchanged for cash, securities or other property or assets; or (3) any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of Company and Company’s
subsidiaries, taken as a whole, to any person other than one of Company’s direct or indirect wholly owned subsidiaries. 

  

	 	(C)	Dealer, despite using commercially reasonable efforts, is unable or reasonably determines, based on the advice of counsel, that it is impractical or illegal, to hedge its exposure with respect to the Transaction in the
public market without registration under the Securities Act or as a result of any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or
have been voluntarily adopted by Dealer). 

 Notwithstanding the foregoing, an Additional Termination Event shall not be
deemed to have occurred if, in the case of (a) a merger or consolidation resulting from clause (A) above or (b) a transaction described in clause (B) above, at least 90% of the consideration (excluding cash payments for
fractional Shares and cash payments pursuant to dissenters’ appraisal rights) in such merger, consolidation or transaction consists of common stock traded or quoted on any of the NASDAQ Global Select Market, the NASDAQ Global Market or the New
York Stock Exchange (or their respective successors) (or which will be so traded or quoted when issued or exchanged in connection with such merger, consolidation or transaction) and, as a result of such merger, consolidation or transaction, the
Shares will consist of such consideration, excluding cash payments for fractional shares or pursuant to statutory appraisal rights.

purposes of clause (A) and clause (B) above: 
  

	 	1.	a “beneficial owner” will be determined in accordance with Rule 13d-3 under the Exchange Act, as in effect on the Premium Payment Date;

equivalents (however designated) of corporate stock; (3) in the case of a partnership or limited liability company, partnership interests (whether general or limited) or membership interests; or (4) any other interest or participation that

collateral. Obligations under the Transaction shall not be set off by either party against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by
operation of law or otherwise. 

  

	 	(j)	Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event)
occurs or is designated with respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the
consideration to be paid to all holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within Company’s control, or (iii) an Event of Default in which Company is the Defaulting Party or a Termination
Event in which Company is the Affected Party other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the
Agreement, in each case that resulted from an event or events outside Company’s control), and if Company would owe any amount to Dealer pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the
Equity Definitions (any such amount, a “Payment Obligation”), then Company shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Company 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) Company remakes the representation set forth in Section 8(a)(vi) 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, Company shall deliver to Dealer the Share Termination Delivery Property on the date (the “Share Termination Payment Date”) on which the Payment Obligation would otherwise be due pursuant to
Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i) below, in satisfaction, subject to Section 9(k)(ii) below, of the relevant Payment
Obligation, in the manner reasonably requested by Dealer free of payment.
		
	Share Termination Delivery	  	
	Property:	  	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the relevant Payment Obligation divided by the Share Termination Unit Price. The Calculation Agent shall adjust the amount of 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 (without giving
effect to any discount pursuant to Section 9(k)(i)).

  
 20 

			
	Share Termination Unit Price:	  	The value of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its
discretion by commercially reasonable means. In the case of a Private Placement of Share Termination Delivery Units that are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be
determined by the discounted price applicable to such Share Termination Delivery Units, determined in a commercially reasonable manner taking into consideration the liquidity of such Share Termination Delivery Units. In the case of a Registration
Settlement of Share Termination Delivery Units that are Restricted Shares (as defined below) as set forth in Section 9(k)(ii) below, notwithstanding the foregoing, the Share Termination Unit Price shall be the Settlement Price 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. The Calculation Agent shall notify Company of the Share Termination Unit Price at
the time of notification of such Payment Obligation to Company or, if applicable, at the time the discounted price applicable to the relevant Share Termination Units is determined pursuant to Section 9(k)(i).
		
	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 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. If such Nationalization, Insolvency or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum
possible amount of cash.
		
	Failure to Deliver:	  	Inapplicable
		
	Other applicable provisions:	  	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and 9.12 (as modified above) of the Equity Definitions 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.

  
 21 

	 	(k)	Registration/Private Placement Procedures. If, in the reasonable opinion of Dealer, based on the advice of counsel, following any delivery of Shares or Share Termination Delivery Property to Dealer
hereunder, such Shares or Share Termination Delivery Property would be in the hands of Dealer subject to any applicable restrictions with respect to any registration or qualification requirement or prospectus delivery requirement for such Shares or
Share Termination Delivery Property pursuant to any applicable federal or state securities law (including, without limitation, any such requirement arising under Section 5 of the Securities Act as a result of such Shares or Share Termination
Delivery Property being “restricted securities”, as such term is defined in Rule 144 under the Securities Act, or as a result of the sale of such Shares or Share Termination Delivery Property being subject to paragraph (c) of Rule 145
under the Securities Act) (such Shares or Share Termination Delivery Property, “Restricted Shares”), then delivery of such Restricted Shares shall be effected pursuant to either clause (i) or (ii) below at the election of
Company, unless Dealer waives the need for registration/private placement procedures set forth in (i) and (ii) below. Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants exercised or deemed exercised on any
Expiration Date, Company shall elect, prior to the first Settlement Date for the first applicable Expiration Date, a Private Placement Settlement or Registration Settlement for all deliveries of Restricted Shares for all such Expiration Dates which
election shall be applicable to all remaining Settlement Dates for such Warrants and the procedures in clause (i) or clause (ii) below shall apply for all such delivered Restricted Shares on an aggregate basis commencing after the final
Settlement Date for such Warrants. The Calculation Agent shall make reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a single Private Placement or Registration Settlement for such aggregate Restricted
Shares delivered hereunder. 

  

	 	(i)	 If Company elects to settle the Transaction pursuant to this clause (i) (a “Private Placement
Settlement”), then delivery of Restricted Shares by Company shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Dealer; provided that Company may not elect a
Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would make unavailable either the exemption pursuant to Section 4(a)(2) of the Securities Act for the sale by Company to Dealer
(or any affiliate designated by Dealer) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of Dealer). The
Private Placement Settlement of such Restricted Shares shall include 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 Restricted Shares by Dealer that is not a major competitor of Company previously identified by Company to Dealer in writing, in each case, that agrees to enter into a confidentiality agreement with Company in customary form for due diligence
investigations similar in scope), opinions and certificates, and such other documentation as is customary for private placement agreements for private placements of equity securities of comparable size of companies of comparable size, maturity and
line of business, all reasonably acceptable to Dealer. In the case of a Private Placement Settlement, Dealer shall determine a commercially reasonable discount to the Share Termination Unit Price (in the case of settlement of Share Termination
Delivery Units pursuant to Section 9(j) above) or premium to any Settlement Price (in the case of settlement of Shares pursuant to Section 2 above) applicable to such Restricted Shares in a commercially reasonable manner and appropriately
adjust the number of such Restricted Shares to be delivered to Dealer hereunder, which discount or premium, as the case may be, shall only take into account the illiquidity resulting from the fact that the Restricted Shares will not be registered
for resale and any commercially reasonable fees and expenses of Dealer (and any affiliate thereof) in connection with such resale. Notwithstanding anything to the contrary in the Agreement or this Confirmation, the date of delivery of such
Restricted Shares shall be the Exchange Business Day following 

  
 22 

	 	
notice by Dealer to Company of such applicable discount or premium, as the case may be, and the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of
doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Share Termination Payment Date (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or on
the Settlement Date for such Restricted Shares (in the case of settlement in Shares pursuant to Section 2 above). 

  

	 	(ii)	If Company elects to settle the Transaction pursuant to this clause (ii) (a “Registration Settlement”), then Company shall promptly (but in any event no later than the beginning of the Resale Period)
file and use its reasonable best efforts to make effective under the Securities Act a registration statement or supplement or amend an outstanding registration statement in form and substance reasonably satisfactory to Dealer, to cover the resale of
such Restricted Shares in accordance with customary resale registration procedures, including covenants, conditions, representations, underwriting discounts (if applicable), commissions (if applicable), indemnities, due diligence rights, opinions
and certificates, and such other documentation as is customary for equity resale underwriting agreements for registered secondary offerings of equity securities of comparable size of companies of comparable size, maturity and line of business, all
reasonably acceptable to Dealer. If Dealer, in its sole reasonable discretion, is not satisfied with such procedures and documentation Private Placement Settlement shall apply. If Dealer is satisfied with such procedures and documentation, it shall
sell the Restricted Shares pursuant to such registration statement during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Restricted Shares (which, for the avoidance of doubt, shall
be (x) the Share Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to Section 9(j) above or (y) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants)
and ending on the earliest of (i) the Exchange Business Day on which Dealer completes the sale of all Restricted Shares in a commercially reasonable manner or, in the case of settlement of Share Termination Delivery Units, a sufficient number
of Restricted Shares so that the realized net proceeds of such sales equals or exceeds the Payment Obligation (as defined above), (ii) the date upon which all Restricted Shares have been sold or transferred pursuant to Rule 144 (or similar
provisions then in force) or Rule 145(d)(2) (or any similar provision then in force) under the Securities Act and (iii) the date upon which all Restricted Shares may be sold or transferred by a
non-affiliate pursuant to Rule 144 (or any similar provision then in force) or Rule 145(d)(2) (or any similar provision then in force) under the Securities Act. If the Payment Obligation exceeds the realized
net proceeds from such resale, Company shall transfer to Dealer by the open of the regular trading session on the Exchange on the Exchange Business Day immediately following such resale the amount of such excess (the “Additional
Amount”) in cash or in a number of Shares (“Make-whole Shares”) in an amount that, based on the Settlement Price on such day (as if such day was the “Valuation Date” for purposes of computing such Settlement
Price), has a dollar value equal to the Additional Amount. The Resale Period shall continue to enable the sale of the Make-whole Shares. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration
Settlement shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. In no event shall Company deliver a number of Restricted Shares on any day greater than the Maximum Number of Shares for such day.

  

	 	(iii)	 Without limiting the generality of the foregoing, Company agrees that (A) any Restricted Shares delivered to
Dealer may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without any further action by Dealer and (B) after the period of 6 months from the Trade Date (or 1 year from the Trade Date if, at such
time, informational requirements of Rule 144(c) under the Securities Act are not satisfied with respect to Company) has elapsed in respect of any Restricted Shares delivered to Dealer, unless Dealer is an affiliate of Company at such time, or has
been an affiliate of Company in the immediately preceding 90 days, Company shall promptly remove, or cause the 

  
 23 

	 	
transfer agent for such Restricted Shares to remove, any legends referring to any such restrictions or requirements from such Restricted Shares upon request by Dealer (or such affiliate of
Dealer) to Company or such transfer agent, without any requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action
by Dealer (or such affiliate of Dealer). Notwithstanding anything to the contrary herein, to the extent the provisions of Rule 144 of the Securities Act or any successor rule are amended, or the applicable interpretation thereof by the Securities
and Exchange Commission or any court change after the Trade Date, the agreements of Company herein shall be deemed modified to the extent necessary, in the opinion of outside counsel of Company, to comply with Rule 144 of the Securities Act, as in
effect at the time of delivery of the relevant Shares or Share Termination Delivery Property. 

  

	 	(iv)	If the Private Placement Settlement or the Registration Settlement shall not be effected as set forth in clauses (i) or (ii), as applicable, then failure to effect such Private Placement Settlement or such
Registration Settlement shall constitute an Event of Default with respect to which Company shall be the Defaulting Party. 

  

	 	(l)	Limit on Beneficial Ownership. Notwithstanding any other provisions hereof, Dealer may not exercise any Warrant hereunder or be entitled to take delivery of any Shares deliverable hereunder, and Automatic
Exercise shall not apply with respect to any Warrant hereunder, to the extent (but only to the extent) that, after such receipt of any Shares upon the exercise of such Warrant or otherwise hereunder [and after taking into account any Shares
deliverable to Dealer under the letter agreement dated November [    ], 2017 between Dealer and Company regarding Base Warrants (the “Base Warrant
Confirmation”)]7, (i) the Section 16 Percentage would exceed 8.0%, or (ii) the Share Amount would exceed the Applicable Share Limit. Any purported delivery hereunder shall be
void and have no effect to the extent (but only to the extent) that, after such delivery [and after taking into account any Shares deliverable to Dealer under the Base Warrant Confirmation]8, (i)
the Section 16 Percentage would exceed 8.0%, or (ii) the Share Amount would exceed the Applicable Share Limit. If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Company’s
obligation to make such delivery shall not be extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Dealer gives notice to Company that, after such delivery,
(i) the Section 16 Percentage would not exceed 8.0%, and (ii) the Share Amount would not exceed the Applicable Share Limit. 

  

	 	(m)	Share Deliveries. Notwithstanding anything to the contrary herein, Company agrees that any delivery of Shares or Share Termination Delivery Property shall be effected by book-entry transfer through the
facilities of DTC, or any successor depositary, if at the time of delivery, such class of Shares or class of Share Termination Delivery Property is in book-entry form at DTC or such successor depositary. 

 

	 	(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 THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF SUCH A SUIT, ACTION OR PROCEEDING, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTY HAVE BEEN INDUCED TO ENTER INTO THE TRANSACTION, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS PROVIDED HEREIN. 

 
  

	7 	Include in Additional Warrant Confirmation. 

	8 	Include in Additional Warrant Confirmation. 

  
 24 

	 	(o)	Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Company 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 Company relating to such tax treatment and tax structure.

  

	 	(p)	Maximum Share Delivery. 

  

	 	(i)	Notwithstanding any other provision of this Confirmation, the Agreement or the Equity Definitions, in no event will Company at any time be required to deliver on any day a number of Shares greater than [Insert Number
Equal to Two times the Number of Shares on the Trade Date] (the “Maximum Number of Shares”) for such day to Dealer in connection with the Transaction. 

 

	 	(ii)	In the event Company shall not have delivered to Dealer the full number of Shares or Restricted Shares otherwise deliverable by Company to Dealer pursuant to the terms of the Transaction because Company has insufficient
authorized but unissued Shares that are not reserved for other transactions (such deficit, the “Deficit Shares”), Company shall be continually obligated to deliver, from time to time, Shares or Restricted Shares, as the case may be,
to Dealer until the full number of Deficit Shares have been delivered pursuant to this Section 9(p)(ii), when, and to the extent that, (A) Shares are repurchased, acquired or otherwise received by Company or any of its subsidiaries after
the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (B) authorized and unissued Shares previously reserved for issuance in respect of other transactions become no longer so reserved or (C) Company
additionally authorizes any unissued Shares that are not reserved for other transactions; provided that in no event shall Company deliver any Shares or Restricted Shares to Dealer pursuant to this Section 9(p)(ii) to the extent that such
delivery would cause the aggregate number of Shares and Restricted Shares delivered to Dealer on any day to exceed the Maximum Number of Shares for such day. Company shall immediately notify Dealer of the occurrence of any of the foregoing events
(including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares or Restricted Shares, as the case may be, to be delivered) and promptly deliver such Shares or Restricted Shares, as the case may be,
thereafter. 

  

	 	(q)	Right to Extend. Dealer may postpone or add, in a commercially reasonable manner, in whole or in part, any Expiration Date or any other date of valuation or delivery with respect to some or all of the
relevant Warrants (in which event the Calculation Agent shall make appropriate adjustments to the Daily Number of Warrants with respect to one or more Expiration Dates) if Dealer determines, in its commercially reasonable judgment, that such
extension is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions 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 Issuer or an affiliated purchaser of Issuer, be in compliance with applicable legal, regulatory or self-regulatory
requirements (“Requirements”), or with related policies and procedures applicable to Dealer adopted in good faith by Dealer in relation to such Requirements; provided that any such Requirements are generally applicable in
similar transactions of this type with counterparties similar to Company and are applied in a consistent manner in similar transactions with counterparties similar to Company; provided further that in no event shall any Expiration Date for
the Transaction be postponed to a date later than the Final Expiration Date. 

  

	 	(r)	Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Company with respect to the Transaction that are senior to
the claims of common stockholders of Company in any United States bankruptcy proceedings of Company; 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
Company of its obligations and agreements with respect to the Transaction; provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

  
 25 

	 	(s)	Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code (Title
11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 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. 

  

	 	(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 regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend
or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the 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. Company understands, acknowledges and agrees that: (A) at any time on and prior to the last 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 Settlement 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 Settlement Prices, each in a manner that may be adverse to Company. 

  

	 	(v)	Early Unwind. In the event the sale of the [“Underwritten Securities”]9[“Option Securities”]10 (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers for any reason, or Company 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 Company 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 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; provided that Counterparty shall purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates
for the purpose of hedging the Transaction and reimburse Dealer for any costs or expenses (including market losses) relating to the unwinding of its hedging activities in connection with the Transaction (including any loss or cost incurred as a
result of its terminating, liquidating, obtaining or reestablishing any hedge or related trading position). The amount of any such reimbursement shall be determined by Dealer in its sole good faith discretion. Dealer shall notify Counterparty of
such amount and Counterparty shall pay such 

  

	9 	Insert for Base Warrant Confirmation. 

	10 	 Insert for Additional Warrant Confirmation. 

  
 26 

	 	
amount in immediately available funds on the Early Unwind Date. Each of Dealer and Company represents and acknowledges to the other that, subject to the proviso included in this
Section 9(v), upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged. 

  

	 	(w)	Payment by Dealer. In the event that (i) 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) of the Agreement) and, as a result, Dealer owes to Company an amount calculated under Section 6(e) of the Agreement, or (ii) Dealer owes to Company, pursuant to Section 12.7 or
Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero. 

  

	 	(x)	Adjustments. For the avoidance of doubt, whenever the Calculation Agent or Determining Party is called upon to make an adjustment pursuant to the terms of this Confirmation or the Equity Definitions to
take into account the effect of an event, the Calculation Agent or Determining Party shall make such adjustment by reference to the effect of such event on the Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge
position. 

  

	 	(y)	Delivery or Receipt of Cash. For the avoidance of doubt, other than receipt of the Premium by Company, nothing in this Confirmation shall be interpreted as requiring Company to cash settle the Transaction,
except in circumstances where cash settlement is within Company’s control (including, without limitation, where Company elects to deliver or receive cash, or where Company has made Private Placement Settlement unavailable due to the occurrence
of events within its control) or in those circumstances in which holders of Shares would also receive cash. 

  

	 	(z)	Listing of Warrant Shares. Company shall have submitted an application for the listing of the Warrant Shares on the Exchange, and such application and listing shall have been approved by the Exchange,
subject only to official notice of issuance, in each case, on or prior to the Premium Payment Date. Company agrees and acknowledges that such submission and approval 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. 

  

	 	(aa)	Additional ISDA Schedule Terms.  

  

	 	1.	Automatic Early Termination. The “Automatic Early Termination” provision of Section 6(a) of the Agreement will not apply to Dealer and will not apply to Company. 

 

	 	2.	Consent to Recording. Each party (i) consents to the monitoring or recording, at any time and from time to time, by the other party of any and all communications between officers or employees of the parties,
(ii) waives any further notice of such monitoring or recording, and (iii) agrees to notify (and, if required by law, obtain the consent of) its officers and employees with respect to such monitoring or recording. Any such recording may be
submitted in evidence to any court or in any Proceeding for the purpose of establishing any matters pertinent to this Transaction. 

  

	 	3.	Severability. In the event any one or more of the provisions contained in this Confirmation or the Agreement shall be held illegal, invalid or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. 

  

	 	(bb)	Withholding Tax imposed on payments to non-US counterparties under the United States Foreign Account Tax Compliance Act. “Indemnifiable Tax”, as
defined in Section 14 of the Agreement, shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any
agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections
of the Code (a “FATCA Withholding Tax”). For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

  
 27 

	 	(cc)	HIRE Act. “Indemnifiable Tax”, as defined in Section 14 of the Agreement, shall not include any tax imposed on payments treated as dividends from sources within the United States
under Section 871(m) of the Code or any regulations issued thereunder. For the avoidance of doubt, any such tax imposed under Section 871(m) of the Code is a Tax the deduction or withholding of which is required by applicable law for
purposes of Section 2(d) of the Agreement. 

  
 28

this Confirmation and returning it to Dealer.
