This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this

to evade compliance with the federal securities laws.

	 Daily Option Value:

Daily Option Value be less than zero.
		
	 Valid Day:
	  	A day on which (i) there is no Market Disruption Event and (ii) trading in the Shares generally occurs on the Exchange. If the Shares are not listed, quoted or traded on any U.S. securities exchange or any other market,

the market value of one Share on such Valid Day, as determined by the Calculation Agent in a good faith and commercially reasonable manner using, if practicable, a volume-weighted average method substantially similar to the method for determining
the VWAP). The Relevant Price will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.

repurchases, forward contracts or similar transactions (including, without limitation, any discount to average VWAP prices) that are entered into at prevailing market prices and in accordance with customary market terms for transactions of such type
to repurchase the Shares shall not be considered Potential Adjustment Events; provided further that any such open market Share repurchases at prevailing market price or the entry into any such accelerated share repurchase transaction, forward
contract or similar transaction described in the immediately preceding proviso shall constitute a Potential Adjustment Event to the extent that, after giving effect to such transaction, the aggregate number of Shares repurchased during (i) any
calendar year would exceed 5% of the number of Shares outstanding as of the Trade Date, and/or (ii) the term of the Transaction pursuant to all such transactions described in the immediately preceding proviso would exceed 20% of the number of

NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any

Code”)) and Counterparty would be able to purchase the Number of Shares in compliance with the laws of the jurisdiction of Counterparty’s incorporation. 

(x) No U.S. state or local law, rule, regulation or regulatory order applicable to the Shares would give rise to any reporting,

 12 













 
(however defined) Shares; provided that no such representation shall be made by Counterparty with respect to any rules and regulations applicable to Dealer (including FINRA) arising from

 (xi) Counterparty (A) is capable of evaluating

(c) Each of Dealer and Counterparty acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration

Confirmation is (i) a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination
value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “settlement payment” within the meaning of Section 546 of the Bankruptcy Code, and
(ii) a “swap agreement,” as such term is defined in Section 101(53B) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment
amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “transfer” within the meaning of Section 546 of the Bankruptcy Code, and (B) that Dealer is entitled to the
protections afforded by, among other sections, Sections 362(b)(6), 362(b)(17), 362(b)(27), 362(o), 546(e), 546(g), 546(j), 548(d)(2), 555, 560 and 561 of the Bankruptcy Code. 

(e) As a condition to the effectiveness of the Transaction, Counterparty shall deliver to Dealer an opinion of counsel, dated as of the
Effective Date, in substantially the form attached hereto as Annex B. 
 (f) Counterparty understands that notwithstanding any other
relationship between Counterparty and Dealer and its affiliates, in connection with the Transaction and any other over-the-counter derivative transactions between
Counterparty and Dealer or its affiliates, Dealer or its affiliates is acting as principal and is not a fiduciary or advisor in respect of any such transaction, including any entry, exercise, amendment, unwind or termination thereof. 

8. Other Provisions: 
 (a)
Right to Extend. Dealer may divide any Component into additional Components and designate the Expiration Date and the Number of Options for each such Component if Dealer determines, in good faith and a reasonable manner, that such further
division is necessary or advisable to preserve Dealer’s hedging or hedge unwind activity assuming such dealer maintains a commercially reasonable hedge position 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 

  
 13 













 
Counterparty or an affiliated purchaser of Counterparty, be compliant and consistent with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures,
generally applicable to transactions of the type of the Transactions; provided that in no event shall any Expiration Date for any Component be postponed to a date later than the Final Termination Date.  

(b) Additional Termination Events. (i) Promptly (but in any event within ten Scheduled Trading Days) following any repurchase,
redemption or conversion and, in each case, cancellation of any of the Counterparty’s [__]% Convertible Senior Notes due 2024 (the “Convertible Notes”) issued pursuant to the Counterparty’s indenture (the
“Indenture”) to be dated August [__], 2019 between the Counterparty and U.S. Bank National Association, as trustee, Counterparty may notify Dealer in writing of such repurchase or conversion and, in either case, cancellation and the
number of Convertible Notes so repurchased, redeemed or converted and, in each case, cancelled (any such notice specifying that such notice is being made by the Counterparty pursuant to Section 8(b) hereof, a “Repurchase
Notice” and any such event, a “Repurchase Event”). Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repurchase Notice, within the applicable time period
set forth in the preceding sentence, and (y) a written representation and warranty by Counterparty that, as of the date of such Repurchase Notice, Counterparty is not in possession of any material
non-public information regarding Counterparty or the Shares, shall constitute an Additional Termination Event as provided in this paragraph. Upon receipt of any such Repurchase Notice and the related written
representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repurchase Notice 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) [(x)]6 the number of shares of Common stock underlying the Convertible Notes applicable to the Transaction that is specified in
such Repurchase Notice 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 [minus (y) the number
of Repurchase Options (as defined in the Base Call Option Transaction dated August [__], 2019 between Dealer and Counterparty (the “Base Call Option Transaction Confirmation”), if any, that relate to such Convertible Notes (and for
purposes of determining whether any Options under this Confirmation or under the Base Call Option Transaction Confirmation will be among the Repurchase Options hereunder or under, and as defined in, the Base Call Option Transaction Confirmation, the
Convertible Notes specified in such Repurchase Notice shall be allocated first to the Base Call Option Transaction Confirmation until all Options thereunder are exercised or terminated)]7. 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. 
 (ii) Notwithstanding anything to the contrary in this Confirmation, if an event of default with respect to
Counterparty occurs under the terms of the Convertible Notes as set forth in Section [6.01] of the Indenture and such event of default results in the Convertible Notes being accelerated and declared due and payable, then such event of default shall
constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected
Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement (which Early Termination Date shall be on or as promptly as reasonably practicable after Dealer becomes
aware of the occurrence of such acceleration). 
 (c) 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 
  

 
  

	6 	 Include for additional capped call 



	7 	 Include for additional capped call 



  
 14 













 
Termination Event in which Counterparty is the Affected Party, which Event of Default or Termination Event resulted from an event or events within the Counterparty’s control), and if Dealer
would owe any amount to Counterparty pursuant to Section 6(d)(ii) and 6(e) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer
shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below) unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m.
(New York City time) on the 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) as of the date of such election, Counterparty represents that is not in possession of any material non-public information regarding Counterparty or the Shares, and that
such election is being made in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws, and (c) Dealer agrees, in its commercially reasonable discretion, to such election, in which case the provisions
of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) and 6(e) of the Agreement, as the case may be, shall apply. 
  

			
	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 of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of
notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider a variety of factors, including the market price of the Share
Termination Delivery Units and/or the purchase price paid in connection with the commercially reasonable purchase of Share Termination Delivery Property.
		
	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


  
 15 














			
	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.

 (d) Disposition of Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable
judgment of Dealer, based on the advice of legal counsel, the Shares acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction (the “Hedge Shares”) cannot be sold in the U.S. public market by
Dealer without registration under the Securities Act, Counterparty shall, at its election: (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, use its commercially reasonable efforts to make available to Dealer an
effective registration statement under the Securities Act to cover the resale of such Hedge Shares and (A) enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement
for a registered offering for companies of a similar size in a similar industry, (B) provide accountant’s “comfort” letters in customary form for registered offerings of equity securities for companies of a similar size in a
similar industry, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty in customary form for registered offerings of equity securities for companies of a similar size in a similar industry, (D) provide
other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities for companies of a similar size in a similar industry and (E) afford Dealer a reasonable opportunity to conduct a
“due diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities for companies of a similar size in a similar industry; provided, however, that, if Counterparty elects
clause (i) above but Dealer, in its commercially 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 Section 8(d) shall apply at the election of Counterparty; (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement
agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of companies of a similar size in a similar industry, in form and substance commercially reasonably satisfactory to Dealer
using best efforts to 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 Hedge Shares from Dealer),
opinions and certificates and such other documentation as is customary for private placements agreements of equity securities of companies of a similar size in a similar industry, as is reasonably acceptable to Dealer (in which case, the Calculation
Agent shall make any adjustments to the terms of the Transaction that are necessary, in its good faith and commercially reasonable judgment, to compensate Dealer for any customary liquidity discount from the public market price of the Shares
incurred on the sale of Hedge Shares in a private placement); provided that no “comfort letter” or accountants’ consent shall be required to be delivered in connection with any private placements; or (iii) purchase the
Hedge Shares from Dealer at the Relevant Price on such Exchange Business Days, and in the amounts, requested by Dealer. 
 (e) Repurchase
Notices. Counterparty shall, at least one Scheduled Valid Day prior to any day on which Counterparty intends to effect any repurchase of Shares, give Dealer written notice of such repurchase (a “Repurchase Notice”) on such day
if, following such repurchase, the Notice Percentage would reasonably be expected to be (i) greater than [    ]8% or (ii) greater by 0.5% than the Notice Percentage
included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the Notice Percentage as of the date hereof). The “Notice Percentage” as of any day is the fraction,
expressed as a percentage, the numerator of which is the Number of Shares and the denominator of which is the number of Shares outstanding on such day. In the event that Counterparty fails to provide Dealer with a Repurchase Notice on the day and in
the manner specified in this Section 8(e) then Counterparty agrees to indemnify and hold harmless Dealer, its affiliates 
  

 

	8 	 To be 0.5% higher than the number of Shares underlying the capped call (including any additional capped call)
of the Dealer with the highest Applicable Percentage. 



  
 16 













 
and their respective directors, officers, employees, agents and controlling persons (Dealer and each such person being an “Indemnified Party”) from and against any and all losses
(including losses relating to the 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 and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable
securities laws, including without limitation, Section 16 of the Exchange Act or under any U.S. state or federal law, regulation or regulatory order, in each case relating to or arising out of such failure. If for any reason the foregoing
indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a
result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified Party for all reasonable expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Counterparty) in
connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such
claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty, in each case relating to or arising out of such failure. This indemnity shall survive the completion of the Transaction contemplated by this Confirmation and
any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement shall inure to the benefit of any permitted assignee of Dealer. Counterparty will not be liable under this indemnity provision to the extent any
loss, claim, damage, liability or expense is found in a final judgment by a court to have resulted from Dealer’s gross negligence or willful misconduct. 

(f) Transfer and Assignment. Either party may transfer or assign any of its rights or obligations under the Transaction with the prior
written consent of the non-transferring party, such consent not to be unreasonably withheld or delayed; provided that Dealer may transfer or assign without any consent of Counterparty its rights and
obligations hereunder, in whole or in part, to (A) any affiliate of Dealer whose obligations would be guaranteed by Dealer [or Dealer Parent]9 or (B) any person (including any affiliate
of Dealer whose obligations are not guaranteed in the manner described in clause (A)) or any person whose obligations would be guaranteed by a person (a “Designated Transferee”), in either case under this clause (B), with a rating
for its long-term, unsecured and unsubordinated indebtedness at least equivalent to Dealer’s (or its guarantor’s), provided, however, that, in the case of this clause (B), in no event shall the credit rating of the Designated
Transferee or of its guarantor (whichever is higher) be lower than A3 from Moody’s Investor Service, Inc. or its successor or A- from Standard and Poor’s Rating Group, Inc. or its successor;
provided further that (i) Dealer will notify Counterparty in writing prior to any proposed transfer or assignment to a Designated Transferee, (ii) after any such transfer, Counterparty will not, as a result of any withholding or
deduction made by the transferee or assignee as a result of any tax, receive from the such transferee or assignee on any payment date or delivery date (after accounting for amounts paid under Section 2(d)(i)(4) of the Agreement as well as such
withholding or deduction) an amount or a number of Shares, as applicable, lower than the amount or the number of Shares, as applicable, that Dealer would have been required to pay or deliver to Counterparty in the absence of such transfer (except to
the extent such lower amount or number results from a change in law after the date of such transfer), and (iii) Dealer shall cause the transferee or assignee to make the Payee Tax Representations and provide Counterparty with a complete and
accurate U.S. Internal Revenue Service Form W-9 or W-8 (as applicable) and any other tax documentation as may be reasonably requested by Counterparty to permit
Counterparty to make any necessary determinations pursuant to clause (ii) of this proviso prior to becoming a party to the Transaction. If at any time at which (1) the Equity Percentage exceeds 8.0% or (2) Dealer, Dealer Group (as
defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a “Dealer Person”) under the Business Combinations Statute or other federal,
state or local law, rule, regulation or regulatory order or organizational documents or contracts of Counterparty 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 in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting, registration, filing or notification obligations or other
requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person under Applicable Restrictions and with respect to which such requirements have not been met or the relevant approval has not been received
minus (y) 1% of the number of Shares outstanding on the date of determination (either such condition described in clause (1) or (2), an “Excess Ownership Position”), 

 
  

	9 	 If applicable 



  
 17 













 
if Dealer, in its reasonable discretion, is unable to effect a transfer or assignment to a third party in accordance with the requirements set forth above after its commercially reasonable
efforts on pricing and terms and within a time period reasonably acceptable to Dealer such that an Excess Ownership Position no longer exists, Dealer may designate any Scheduled Valid Day as an Early Termination Date with respect to a portion (the
“Terminated Portion”) of the Transaction, such that an Excess Ownership Position no longer exists following such partial termination. In the event that Dealer so designates an Early Termination Date with respect to a portion of the
Transaction, a payment or delivery shall be made pursuant to Section 6 of the Agreement and Section 8(c) of this Confirmation as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical
to the Terminated Portion of the Transaction, (ii) Counterparty were the sole Affected Party with respect to such partial termination, (iii) such portion of the Transaction were the only Terminated Transaction and (iv) Dealer were the
party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement and to determine the amount payable pursuant to Section 6(e) of the Agreement. The “Equity 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 subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of
the Exchange Act and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Dealer (collectively, “Dealer Group”) “beneficially
own” (within the meaning of Section 13 of the Exchange Act) without duplication on such day and (B) the denominator of which is the number of Shares outstanding on such day. 

In the case of a transfer or assignment by Counterparty of its rights and obligations hereunder and under the Agreement, in whole or in part
(any such Options so transferred or assigned, the “Transfer Options”), to any party, withholding of such consent by Dealer shall not be considered unreasonable if such transfer or assignment does not meet the 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 8(e) or any obligations under Section 2 (regarding Extraordinary Events) or 8(d) of this Confirmation; 

(B) Any Transfer Options shall only be transferred or assigned to a third party that is a U.S. person (as defined by 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, undertakings 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 customary legal opinions with respect to securities laws and other matters by such third party and Counterparty as are reasonably requested and reasonably satisfactory to Dealer; 

(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 have caused the transferee to make such
Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

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

  
 18 













 (g) Staggered Settlement. If Dealer determines reasonably and in good faith that the
number of Shares required to be delivered to Counterparty hereunder on any Settlement Date would result in an Excess Ownership Position, then Dealer may, by notice to Counterparty prior to such Settlement Date (a “Nominal Settlement
Date”), elect to deliver any Shares due to be delivered on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows: 

(i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or
prior to the 20th Exchange Business Day after such Nominal Settlement Date) or delivery times and how it will allocate the Shares it is required to deliver under “Delivery Obligation”
(above) among the Staggered Settlement Dates or delivery times; and 
 (ii) the aggregate number of Shares that Dealer will
deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; provided that in no event shall
any Staggered Settlement Date be a date later than the Final Termination Date. 
 (h) Disclosure. Effective from the date of
commencement of discussions concerning the Transaction, Counterparty and Dealer and each of their 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.  

(i) No Netting and Set-off. The provisions of Section 2(c) of the Agreement shall not
apply to the Transaction. Each party waives any and all rights it may have to set-off delivery or payment obligations it owes to the other party under the Transaction against any delivery or payment
obligations owed to it by the other party, whether arising under the Agreement, under any other agreement between parties hereto, by operation of law or otherwise. 

(j) Equity Rights. Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights with respect to the
Transaction that are senior to the claims of common stockholders in the event of Counterparty’s bankruptcy. For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than during
Counterparty’s bankruptcy to any claim arising as a result of a breach by Counterparty of any of its obligations under this Confirmation or the Agreement. For the avoidance of doubt, the parties acknowledge that the obligations of Counterparty
under this Confirmation are not secured by any collateral that would otherwise secure the obligations of Counterparty herein under or pursuant to any other agreement.

Share Option Transaction, then following the announcement or occurrence of any Potential Adjustment Event, the Calculation Agent will determine whether such Potential Adjustment Event has, in the commercially reasonable judgment of the Calculation

(y) an observable index, other than an index calculated measured solely by reference to Counterparty’s own operations) and, if so, will (i) make appropriate adjustment(s), if any, determined in a commercially reasonable manner, to any
one or more of: and, the portion of such sentence immediately preceding clause (ii) thereof is hereby amended by deleting the words “diluting or concentrative” and the words “(provided that no adjustments will be made to
account solely for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares)” and replacing such latter phrase with the words “(provided that, solely in the case of Sections 11.2(e)(i),
(ii)(A), (iv) and (v), no adjustments will be made to account solely for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares but, for the avoidance of doubt, solely in the case of Sections
11.2(e)(ii)(B) through (D), (iii) (vi) and (vii) adjustments may be made to account solely for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares)”; 

(iii) Section 11.2(a) of the Equity Definitions is hereby amended by (1) deleting the words “in the
determination of the Calculation Agent, a diluting or concentrative effect” and replacing these words with “in the commercially reasonable judgment of the Calculation Agent, a material economic effect”; and (2) adding at the end
thereof “; provided that such event is not based on (i) an observable market, other than the market for Counterpart’s own stock or (ii) an observable index, other than an index calculated measured solely by reference to
Counterparty’s own operations”; 
 (iv) Section 11.2(e)(vii) of the Equity Definitions is hereby amended and
restated as follows: “any other corporate event involving the Issuer that in the commercially reasonable judgment of the Calculation Agent has a material economic effect on the theoretical value of the Shares or options of the Shares;

reference to Counterparty’s own operations.”;

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. 

(p) Delivery or Receipt of Cash. For the avoidance of doubt, other than payment of the Premium by Counterparty, nothing in this

receive cash) or in those circumstances in which holders of Shares would also receive cash. 
 (q) Waiver of Jury Trial. EACH

deliver to Dealer one duly executed and completed United States Internal Revenue Service Form W-9 (or successor thereto) and Dealer agrees to deliver to Counterparty, as applicable, a U.S. Internal Revenue
Service Form W-8 or Form W-9 (or successor thereto). Such forms or documents shall be delivered upon (i) execution of this Confirmation, (ii) Counterparty or
Dealer, as applicable, learning that any such tax form previously provided by it has become obsolete or incorrect, and (iii) reasonable request of the other party.
