 Dear Ladies and Gentlemen: 

The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the above-referenced
transaction entered into on the Trade Date specified below (the “Transaction”) between [___] (“Dealer”) and BigCommerce Holdings, Inc. (“Counterparty”). This communication constitutes a
“Confirmation” as referred to in the ISDA Master Agreement specified below. 
 1. This Confirmation is subject to, and
incorporates, the definitions and provisions of the 2006 ISDA Definitions (the “2006 Definitions”) and the definitions and provisions of the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”, and
together with the 2006 Definitions, the “Definitions”), in each case, as published by the International Swaps and Derivatives Association, Inc. (“ISDA”). In the event of any inconsistency between the 2006
Definitions and the Equity Definitions, the Equity Definitions will govern and in the event of any inconsistency between terms defined in the Equity Definitions and this Confirmation, this Confirmation shall govern. 

This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation
relates. This Confirmation shall be subject to an agreement (the “Agreement”) in the form of the 2002 ISDA Master Agreement as if Dealer and Counterparty had executed an agreement in such form on the Trade Date (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 [__________] (“Guarantor”) dated as of
the Trade Date in substantially the form attached hereto as Schedule 1 as a Credit Support Document, (iii) the election of Guarantor as Credit Support Provider in relation to Dealer and (iv)] [and (ii)] the election that the “Cross
Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Dealer, (a) with a “Threshold Amount” of 3% of the shareholders’ equity of
[Dealer][Dealer’s ultimate parent)] on the Trade Date, (b) “Specified Indebtedness” having the meaning set forth in Section 14 of the Agreement, except that it shall not include any obligation in respect of deposits
received in the ordinary course of Dealer’s banking business, (c) the phrase “, or becoming capable at such time of being declared,” shall be deleted from clause (1) of such Section 5(a)(vi) of the Agreement, and
(d) the following sentence shall be added to the end of Section 5(a)(vi) of the Agreement: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (i) the default was
caused solely by error or omission of an administrative or operational nature; (ii) funds were available to enable the relevant party to make 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.”). 

  
 1 













 All provisions contained in, or incorporated by reference to, the Agreement will govern this
Confirmation except as expressly modified herein. In the event of any inconsistency between this Confirmation and either the Definitions or the Agreement, this Confirmation shall govern. 

The Transaction hereunder shall be the sole Transaction under the Agreement. If there exists any ISDA Master Agreement between Dealer and
Counterparty or any confirmation or other agreement between Dealer and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Dealer and Counterparty, then notwithstanding anything to the contrary in such ISDA Master
Agreement, such confirmation or agreement or any other agreement to which Dealer and Counterparty are parties, the Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

reasonable manner. Notwithstanding the foregoing and anything to the contrary in the Equity Definitions, if a Market Disruption Event occurs on any Expiration Date, the Calculation Agent may determine in a good faith and commercially reasonable
manner that such Expiration Date is a Disrupted Day only in part, in which case the Calculation Agent shall make commercially reasonable adjustments to the Number of Options for the relevant Component for which such day shall be the Expiration Date,

such Component, in which case Automatic Exercise will not apply with respect to such Component. “In-the-Money” means, in respect of any Component, that

reasonable manner.

Without limiting the generality of the foregoing, Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Sections 9
and 10(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations promulgated thereunder in respect of such election.

pay or deliver, as the case may be, to Counterparty on the Settlement Date:
  

(i) an amount of cash (the “Combination Settlement Cash Amount”) equal to the lesser of
(A) the Specified Cash Amount divided by the number of Components for the Transaction and (B) the Daily Option Value on the Expiration Date of such Component; and

 
 (ii)  a number of Shares (the
“Combination Settlement Share Amount”) equal to (A) the excess of (1) the Daily Option Value on the Expiration Date of such Component over the (2) the Specified Cash Amount divided by the number of Components
for the Transaction, divided by (B) the Relevant Price on such Expiration Date.
 Dealer will deliver cash in lieu of any fractional Shares to be
delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the Expiration Date of such Component.

			
		 	 Daily Option Value:
	  	For any Component, an amount equal to (i) the Number of Options in such Component, multiplied by (ii) the Option Entitlement, multiplied by (iii) (A) the lesser of the Relevant Price on the Expiration

available) (the “VWAP”) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such Valid Day (or if such volume-weighted average price is unavailable at
such time, the market value of one Share on such Valid Day, as determined by the Calculation Agent in 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.
			
		 	 Settlement Date:
	  	For all Components of the Transaction, the date one Settlement Cycle immediately following the Expiration Date for the Component with the latest scheduled Expiration Date.

number of Shares outstanding as of the Trade Date, provided further that such repurchases shall be (x) pursuant to Rule 10b-18 of the Exchange Act (“Rule
10b-18”), Rule 10b5-1 of the Exchange Act or pursuant to forward contracts or accelerated stock repurchase contracts or similar derivatives transactions on

references to “Announcement Event” and references to “Tender Offer Date” shall be replaced by references to “date of such Announcement Event” in the definition of Modified Calculation Agent Adjustment set forth in
Section 12.3(d), (y) the phrase “exercise, settlement, payment or any other terms of the Transaction (including, without limitation, the spread)” in the third and fourth lines of the definition of Modified Calculation Agent Adjustment

determined in good faith by the Calculation Agent) period of time prior to or after the Announcement Event” shall be inserted prior to the word “which” in the seventh line, and (z) for the avoidance of doubt, the Calculation
Agent shall, in good faith and a commercially reasonable manner, determine whether the relevant Announcement Event has had a material economic effect on the Transaction and, if so, shall adjust the Cap Price accordingly to take into account such
economic effect on one or more occasions on or after the date of the Announcement Event up to, and including, the final Expiration Date, any Early Termination Date and/or any other date of cancellation, it being understood that (i) any
adjustment in respect of an Announcement Event shall take into account any earlier adjustment relating to the same Announcement Event and shall not be duplicative with any other adjustment or cancellation valuation made pursuant to this
Confirmation, the Equity Definitions or the Agreement and (ii) in making any adjustment the Calculation Agent shall solely take into account changes in stock price, volatility, expected dividends, stock loan rate, and liquidity relevant to the
Shares or to such Transaction. An Announcement Event shall be an “Extraordinary Event” for purposes of the Equity Definitions, to which Article 12 of the Equity Definitions is applicable; provided further that upon the Calculation
Agent making an adjustment, determined in a commercially reasonable manner, to the Cap Price upon any Announcement Event, then the Calculation Agent shall make an adjustment to the Cap Price upon any announcement regarding the same event that gave
rise to the original Announcement Event regarding the abandonment of any such event to the extent necessary to reflect the economic effect of such subsequent announcement on the Transaction (provided that in no event shall the Cap Price be
less than the Strike Price).
			
		 	 Announcement Event:
	  	(i) The public announcement (whether by Counterparty, a subsidiary, affiliate, agent or representative of Counterparty, or a Valid Third Party Entity (any such person or entity, a “Relevant Party”)) of any
transaction or event that the Calculation Agent determines is reasonably likely to be completed and that, if completed, would constitute a Merger Event or Tender Offer (it being understood and agreed that in determining whether such transaction or
event is reasonably likely to be completed, the Calculation Agent shall take into consideration whether the relevant announcement by such party has had a material effect on the Shares and/or options on the Shares), or
the


  
 8 














					
			
		 		  	announcement by a Relevant Party of any intention to enter into a Merger Event or Tender Offer, (ii) the public announcement by a Relevant Party of any potential acquisition or disposition by Counterparty and/or its
subsidiaries where the consideration exceeds 35% of the market capitalization of the Counterparty as of the date of such announcement (an “Acquisition Transaction”) (iii) the public announcement by a Relevant Party of an intention
by Counterparty or such other Relevant Party to solicit or enter into, or to explore strategic alternatives or other similar undertaking that may include, a Merger Event, Tender Offer or Acquisition Transaction, or (iv) any subsequent public
announcement by a Relevant Party of a change to a transaction or intention that is the subject of an announcement of the type described in clause (i), (ii) or (iii) of this sentence (including, without limitation, a new announcement relating to
such a transaction or intention or the announcement of a withdrawal from, or the abandonment or discontinuation of, such a transaction or intention), as determined by the Calculation Agent in a commercially reasonable manner. For the avoidance of
doubt, the occurrence of an Announcement Event with respect to any transaction or intention shall not preclude the occurrence of a later Announcement Event with respect to such transaction or intention. For purposes of this definition of
“Announcement Event,” “Merger Event” shall mean such term as defined under Section 12.1(b) of the Equity Definitions (but, for the avoidance of doubt, the remainder of the definition of “Merger Event” in
Section 12.1(b) of the Equity Definitions following the definition of “Reverse Merger” therein shall be disregarded).
			
		 	 Valid Third Party Entity:
	  	In respect of any transaction or event, any third party, or its subsidiary, affiliate, agent or representative, that has a bona fide intent to enter into or consummate such transaction or event, it being understood and agreed that
in determining, in a commercially reasonable manner, whether such third party has such a bona fide intent, the Calculation Agent shall take into consideration whether the relevant announcement by such party has had a material economic effect on the
Shares and/or options on the Shares.
			
		 	 Notice of Merger Consideration and Consequences:
	  	Upon the occurrence of a Merger Event that causes the Shares to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), Counterparty shall
reasonably promptly (but in any event prior to the relevant Merger Date) notify the Calculation Agent of (i) the type and amount of consideration that a holder of Shares would have been entitled to in the case of reclassifications,
consolidations, mergers, sales or transfers of assets or other transactions that cause Shares to be converted into the right to receive more than a single type of consideration and (ii) the weighted average of the types and amounts of
consideration to be received by the holders of Shares that affirmatively make such an election.

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

		 	 (a) Change in Law:
	  	Applicable; provided that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the parenthetical beginning after the word “regulation” in the second line thereof with the words

interpretation is applied equally by Dealer to all of its similarly situated counterparties and/or similar transactions.” after the semi-colon in the last line thereof.

Transaction, or (B) realize, recover or remit the proceeds of any such transaction(s) or asset(s), provided that any such inability that is incurred solely due to the deterioration of the creditworthiness of the Hedging Party shall not
be deemed a Hedging Disruption; provided further that 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”.

and documents), do not contain any untrue statement of a material fact or any omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not
misleading.

exercisable for Shares, are not, and shall not be, subject to a “restricted period,” as such term is defined in Regulation M under the Exchange Act (“Regulation M”), and (B) Counterparty is not engaged in any
“distribution,” as such term is defined in Regulation M, other than a distribution meeting the requirements of the exceptions set forth in Rules 101(b)(10) and 102(b)(7) or Rule 102(c)(1)(i) of Regulation M. 

(iii) On the Trade Date, neither Counterparty nor any “affiliate” or “affiliated purchaser” (each as
defined in Rule 10b-18 of the Exchange Act (“Rule 10b-18”)) shall directly or indirectly (including, without limitation, by means of any cash-settled or
other derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or commence any tender offer relating to, any Shares (or an equivalent interest, including a unit of beneficial interest in a
trust or limited partnership or a depository share) or any security convertible into or exchangeable or exercisable for Shares. 

(iv) Without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that neither
Dealer nor any of its affiliates is making any representations or warranties or taking any position or expressing any view with respect to the treatment of the Transaction under any accounting standards including ASC Topic 260, Earnings Per

 13 













 (x) To Counterparty’s knowledge, no U.S. state or local law, rule,
regulation or regulatory order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) as a result of
Dealer or its affiliates owning or holding (however defined) Shares; 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

(b) Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” as defined in
Section 1a(18) of the U.S. Commodity Exchange Act, as amended. 
 (c) Each of Dealer and Counterparty acknowledges that the offer and
sale of the Transaction to it is intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) thereof. Accordingly, Counterparty represents and warrants to Dealer that (i) it has the financial ability to
bear the economic risk of its investment in the Transaction and is able to bear a total loss of its investment and its investments in and liabilities in respect of the Transaction, which it understands are not readily marketable, are not

Dealer and Counterparty agrees and acknowledges that Dealer is a “financial institution,” “swap participant” and “financial participant” within the meaning of Sections 101(22), 101(53C) and 101(22A) of the Bankruptcy
Code. The parties hereto further agree and acknowledge (A) that this 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

 14 













 (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. 

(g) [Each party acknowledges and agrees to be bound by the Conduct Rules of the Financial Industry Regulatory Authority, Inc. applicable to
transactions in options, and further agrees not to violate the position and exercise limits set forth therein. 
 (h) Counterparty represents
and warrants that it has received, read and understands the OTC Options Risk Disclosure Statement and a copy of the most recent disclosure pamphlet prepared by The Options Clearing Corporation entitled “Characteristics and Risks of Standardized
Options”.] 
 (i) Counterparty acknowledges that: 

(i) during the term of the Transaction, 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 establish, adjust or unwind its hedge position with respect to the Transaction; 

(ii) Dealer and its affiliates may also be active in the market for the Shares and derivatives linked to the Shares other than
in connection with hedging activities in relation to the Transaction, including acting as agent or principal and for its own account or on behalf of customers; 

(iii) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in
Counterparty’s securities 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 Transaction in general and the Relevant Prices in particular; 

(iv) any market activities of Dealer and its affiliates with respect to the Shares may affect the market price and volatility
of the Shares, as well as the Relevant Prices, each in a manner that may be adverse to Counterparty; and 
 (v) the
Transaction is a derivatives transaction in which it has purchased from Dealer an option; Dealer may purchase shares for its own account at an average price that may be greater than, or less than, the price paid by Counterparty under the terms of
the Transaction. 
 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 commercially reasonable manner, that such further division would be necessary or advisable to preserve a commercially reasonable dealer’s hedging or hedge unwind
activity with respect to the Transaction in light of existing liquidity conditions or to enable such a dealer to purchase or sell Shares or enter into swap or other derivatives transactions with respect to Shares in connection with its commercially
reasonable hedging, hedge unwind or settlement activity with respect to the Transaction in a manner that would, if such dealer were Counterparty or an affiliated purchaser of Counterparty, be compliant and consistent with applicable legal,
regulatory or self-regulatory requirements generally applicable to transactions of the type of the Transaction, or with related policies and procedures adopted by Dealer in good faith so long as such policies and procedures are generally applicable
in similar situations and applied in a non-discriminatory commercially reasonable manner; provided that in no event shall any Expiration Date for any Component be postponed to a date later than the
Final Termination Date.  

  
 15 













 (b) Additional Termination Events. Promptly (but in any event within ten
Scheduled Trading Days) following any repurchase, redemption or conversion (which conversion occurs prior to the [•][th] Scheduled Trading Day prior to September 15, 2026) of any of the Counterparty’s [•]% Convertible Senior
Notes due 2026 (the “Convertible Notes”) issued pursuant to the Counterparty’s indenture (the “Indenture”) [to be] dated September [•], 2021 between the Counterparty and [U.S. Bank National Association],
as trustee, Counterparty may notify Dealer in writing of (i) such repurchase, redemption or conversion, (ii) the number of Convertible Notes so repurchased, redeemed or converted and (iii) the number of Shares underlying each USD
1,000 principal amount of Convertible Notes (any such notice, a “Repurchase Notification” and any such event, a “Repurchase Event”)[; provided that any “Repurchase Notification” delivered to Dealer
pursuant to the Base Capped Call Transaction Confirmation letter agreement dated September [•], 2021 between Dealer and Counterparty relating to such Convertible Notes (the “Base Call Option Confirmation”) shall be deemed to be
a Repurchase Notification pursuant to this Confirmation and the terms of such Repurchase Notification shall apply, mutatis mutandis, to this Confirmation]. Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer
from Counterparty of (x) any Repurchase Notification, 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
Notification, 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 Notification and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repurchase Notification 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)] [__]% of the aggregate number of Shares underlying the number of Convertible Notes specified in such
Repurchase Notification, divided by the Option Entitlement[, minus (y) 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, and as defined in, the Base Call Option Confirmation will be among the Repurchase Options hereunder or under, and as defined in, the Base Call Option Confirmation, the
number of Convertible Notes specified in such Repurchase Notification shall be allocated first to the Base Call Option Confirmation until all Options thereunder are exercised or terminated)] and (B) the aggregate Number of Options as of the
date Dealer designates such Early Termination Date and, as of such date, the aggregate Number of Options shall be reduced by the number of Repurchase Options on a pro rata basis across all Components, as determined by the Calculation Agent in good
faith and in a commercially reasonable manner. 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 an aggregate 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. 
 (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 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 

  
 16 













 
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 in good faith and in a commercially reasonable manner, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation
Agent shall, in good faith and in a commercially reasonable manner, 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
			
		 	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.


  
 17 













 (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 effecting a commercially reasonable hedge of 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 commercially 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; provided that Dealer
has given Counterparty reasonable notice of its determination and provided Counterparty with reasonable opportunity to satisfy Dealer’s concerns; (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 reasonable 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 then-prevailing market price at one or more times on such Exchange Business Days, and in the amounts, requested by Dealer. This Section 8(d) shall survive the termination, expiration or
early unwind of the Transaction. 
 (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 [__]% and (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); provided that, if such repurchase, or the intention to effect the same, would constitute material non-public information with respect to Counterparty or the Shares, Counterparty
shall make public disclosure thereof at or prior to delivery of such Repurchase Notice. The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the aggregate Number of Shares,
plus the aggregate number of Shares underlying any other call options sold by Dealer to Counterparty 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 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 commercially reasonable losses (including direct 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 and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws, including without 

  
 18 













 
limitation, Section 16 of the Exchange Act 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 commercially reasonable expenses (including commercially reasonable outside 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. Counterparty shall be relieved from liability under this Section 8(e) to the extent that the Indemnified Party fails promptly to
notify Counterparty of any action commenced against it in respect of which indemnity may be sought hereunder (it being understood that any such notice delivered within 30 calendar days of the commencement of any such action shall be deemed to have
been delivered promptly for such purpose), if and to the extent that Counterparty is materially prejudiced by such delayed notification. 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 conclusively found in a final and non-appealable judgment by a court of competent jurisdiction 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 its rights and obligations hereunder, in
whole or in part, to (A) without Counterparty’s consent, 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 assignment, or
(2) whose obligations would be guaranteed by Dealer or Dealer’s ultimate parent or (B) with Counterparty’s consent (such consent not to be unreasonably withheld or delayed) any person (including any affiliate of Dealer not
satisfying 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 or assignment, (x) Counterparty will not be required to pay the transferee or assignee under Section 2(d)(i)(4) of the
Agreement any amount greater than the amount Counterparty would have been required to pay to Dealer in the absence of such transfer or assignment and (y) 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 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 or assignment, 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) prior to becoming a party to the Transaction. 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 any applicable “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”), if Dealer, in its commercially 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 

  
 19 













 
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 (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. 
 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 in the
Internal Revenue Code of 1986, as amended (the “Code”)), and the transferee or assignee shall provide Dealer with a complete and accurate U.S. Internal Revenue Service Form W-9 prior to
becoming a party to the Transaction; 
 (C) such transfer or assignment shall be effected on terms, including any
commercially 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 commercially 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 or assignee on any payment date an amount or number of Shares under Section 2(d)(i)(4) of the Agreement greater than an amount or number of Shares that Dealer would have been required to pay to Counterparty in the
absence of such transfer and assignment; 
 (E) Dealer shall not, as a result of such transfer or assignment, receive from
the transferee or assignee any amount or number of Shares less than it would have been entitled to receive (including under Section 2(d)(i)(4) of the Agreement) in the absence of such transfer or assignment; 

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

 (H) 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. 

  
 20 













 Notwithstanding any other provision in this Confirmation to the contrary requiring or
allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or
other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to
Counterparty to the extent of any such performance. 
 (g) Staggered Settlement. If Dealer determines in good faith and in its
commercially reasonable discretion 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 such Nominal Settlement Date) or delivery times and how it will allocate the Shares it is required to deliver hereunder on the Settlement Date 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
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.  
 (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. 

(k) Early Unwind. In the event the sale of the [“Underwritten Securities”] [“Option Securities”] (as defined
in the Purchase Agreement dated as of September [•], 2021, among Counterparty and [•] as representatives of the Initial Purchasers party thereto (the “Initial Purchasers”)) is not consummated with the Initial Purchasers
for any reason 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. Each of Dealer and Counterparty represents and acknowledges to the other that, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed
fully and finally discharged.

 (l) 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, an Excess Ownership Position, or Illegality (as defined in the Agreement)). 
 (m) Amendments to Equity Definitions and the
Agreement. The following amendments shall be made to the Equity Definitions: 
 (i) solely for purposes of
applying the Equity Definitions and for purposes of this Confirmation, any reference in the Equity Definitions to a Strike Price shall be deemed to be a reference to either of the Strike Price or the Cap Price, or both, as appropriate; 

(ii) for the purpose of any adjustment under Section 11.2(c) of the Equity Definitions, the first sentence of
Section 11.2(c) of the Equity Definitions, prior to clause (A) thereof, is hereby amended to read as follows: “If “Calculation Agent Adjustment” is specified as the Method of Adjustment in the related Confirmation of a 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 Agent,
a material economic effect on the theoretical value of the relevant Shares or options on the Shares (provided that such event is not based on (x) an observable market, other than the market for Counterparty’s own stock or
(y) an observable index, other than an index calculated and 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
Section 11.2(e)(i), (ii)(A), (iv) and (v), no adjustments will be made to account for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares as determined by the Calculation Agent in a
commercially reasonable manner, 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 on the theoretical value of the relevant Shares” and replacing these words with “in the commercially reasonable
judgment of the Calculation Agent, a material economic effect on the theoretical value of the Shares or options on such Shares”; and (2) adding at the end thereof “; provided that such event is not based on (i) an
observable market, other than the market for Counterparty’s own stock or (ii) an observable index, other than an index calculated and 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 on the Shares; provided that such corporate event involving the
Issuer is not based on (a) an observable market, other than the market for Counterparty’s own stock or (b) an observable index, other than an index calculated and measured solely by reference to Counterparty’s own
operations.”; 
 (v) Section 12.7(b) of the Equity Definitions is hereby amended by deleting the words “(and
in any event within five Exchange Business Days) by the parties after” appearing after the words “agreed promptly” and replacing with the words “by the parties on or prior to”; and 

  
 22 













 (vi) Section 12.9(b)(i) of the Equity Definitions is hereby amended by
replacing “either party may elect” with “(x) Dealer may elect or, (y) solely with respect to a “Change in Law”, if Counterparty represents to Dealer in writing at the time of such election that (i) it is not aware
of any material nonpublic information with respect to Counterparty or the Shares and (ii) it is not making such election as part of a plan or scheme to evade compliance with the U.S. federal securities laws, Counterparty may elect”. 

(n) Governing Law. THE AGREEMENT, THIS CONFIRMATION AND ALL MATTERS ARISING IN CONNECTION WITH THE AGREEMENT AND THIS
CONFIRMATION SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REFERENCE TO ITS CHOICE OF LAW DOCTRINE, OTHER THAN TITLE 14 OF THE NEW YORK GENERAL OBLIGATIONS LAW). THE PARTIES HERETO
IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE FEDERAL AND STATE COURTS LOCATED IN THE BOROUGH OF MANHATTAN, IN THE CITY OF NEW YORK IN ANY SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THE AGREEMENT, THIS CONFIRMATION OR ANY
TRANSACTIONS CONTEMPLATED HEREBY. 
 (o) 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 in a
commercially reasonable manner 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
Confirmation shall be interpreted as requiring Counterparty to cash settle the Transaction, except in circumstances where cash settlement is within Counterparty’s control (including, without limitation, where Counterparty elects to deliver or
receive cash) or in those circumstances in which holders of Shares would also receive cash. 
 (q) Waiver of Jury Trial.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHTS TO TRIAL BY JURY WITH RESPECT TO ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THE AGREEMENT, THIS CONFIRMATION OR ANY TRANSACTIONS CONTEMPLATED HEREBY.

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

the Agreement, and for such purposes the Agreement shall be deemed a “Covered Agreement,” Dealer shall be deemed a “Covered Entity” and Counterparty shall be deemed a “Counterparty Entity.” In the event that, after the
date of the Agreement, both parties hereto become adhering parties to the Protocol, the terms of the Protocol will replace the terms of this paragraph. In the event of any inconsistencies between the Agreement and the terms of the Protocol, the
Bilateral Agreement or the Bilateral Terms (each, the “QFC Stay Terms”), as applicable, the QFC Stay Terms will govern. Terms used in this paragraph without definition shall have the meanings assigned to them under the QFC Stay

FDIC under the Federal Deposit Insurance Act and the Orderly Liquidation Authority under Title II of the Dodd Frank Wall Street Reform and Consumer Protection Act and the override of default rights related directly or indirectly to the entry of an

 (z)
[CARES Act. Counterparty acknowledges that the Transaction may constitute a purchase of its equity securities. Counterparty further acknowledges that, pursuant to the provisions of the Coronavirus Aid, Relief and Economic Security Act (the
“CARES Act”), Counterparty would be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans (as that term is defined in the CARES
Act) under section 4003(b) of the CARES Act. Counterparty further acknowledges that it may be required to agree to certain time-bound restrictions on its ability to purchase its equity securities if it receives loans, loan guarantees or direct loans
(as that term is defined in the CARES Act) under programs or facilities established by the Board of Governors of the Federal Reserve System for the purpose of providing liquidity to the financial system (together with loans, loan guarantees or
direct loans under section 4003(b) of the CARES Act, “Governmental Financial Assistance”). Accordingly, Counterparty represents and warrants that it has not applied for, has no present intention to apply for and, prior to the
termination or settlement of the Transaction, has no intention to apply for Governmental Financial Assistance under any governmental program or facility that (a) is established under the CARES Act or the Federal Reserve Act, as amended, and
(b) requires, as a condition of such Governmental Financial Assistance, that Counterparty agree, attest, certify or warrant that it has not, as of the date specified in such condition, repurchased, or will not repurchase, any equity security of
Counterparty; provided that Counterparty may apply for any such governmental assistance if Counterparty determines based on the advice of nationally recognized outside counsel that the terms of the Transaction would not cause Counterparty to
fail to satisfy any condition for application for or receipt or retention of such governmental assistance based on the terms of the relevant program or facility as of the date of such advice. Counterparty agrees that if it or any of its subsidiaries
applies for any such governmental assistance, then to the extent required in any applicable application, it or such subsidiary shall disclose the Transaction to the relevant governmental authority. Counterparty further represents and warrants that
the Premium is not being paid, in whole or in part, directly or indirectly, with funds received under or pursuant to any program or facility, including the U.S. Small Business Administration’s “Paycheck Protection Program”, that
(a) is established under applicable law (whether in existence as of the Trade Date or subsequently enacted, adopted or amended), including without limitation the CARES Act and the Federal Reserve Act, as amended, and (b) requires under
such applicable law (or any regulation, guidance, interpretation or other pronouncement of a governmental authority with jurisdiction for such program or facility) that such funds be used for specified or enumerated purposes that do not include the
purchase of the Transaction (either by specific reference to the Transaction or by general reference to transactions with the attributes of the Transaction in all relevant respects).]
