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 Halozyme Therapeutics, Inc.

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.

Certain defined terms used herein are based on terms that are defined in the Offering Memorandum dated November 5, 2025 (the “Offering Memorandum”) relating to the [ ]% Convertible Senior Notes due [2031][2032] (as originally issued by Counterparty, the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty in an aggregate initial principal amount of USD 650,000,000 (as increased by [up to]⁴ an aggregate principal amount of USD 100,000,000 [if and to the extent that]⁵[pursuant to the exercise by]⁶ the Initial Purchasers (as defined herein) [exercise]⁷[of]⁸ their option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture [to be]⁹ dated November 12, 2025 between Counterparty and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Indenture”).

If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. The parties further acknowledge that the Indenture section numbers used herein are based on the [draft of the Indenture last reviewed by Dealer as of the date of this Confirmation, and if any such section numbers are changed in the Indenture as executed, the parties will amend this Confirmation in good faith to preserve the intent of the parties]¹⁰[Indenture as executed]¹¹.

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 ISDA 2002 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)]¹² [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, such provisions shall exclude any default if (i) such default results solely from an 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.”).

Combination Settlement:		If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant Settlement Date for each such Option: (i) cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and (ii) Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero; provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option. Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

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

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


Applicable Limit:		For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, paid to the Holder (as such term is defined in the Indenture) of the related Convertible Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the related Convertible Note upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

The Relevant Price will be determined without regard to after-hours trading or any other trading outside of the regular trading session.

period during the term of the Transaction pursuant to all such transactions would not exceed 12% of the number of Shares outstanding as of the beginning of such 12-month period, each as determined by the Calculation Agent and as adjusted by the Calculation Agent in a commercially reasonable manner to account for any subdivision or combination with respect to the Shares and (ii) in the case of any accelerated share repurchase or other structured share repurchases, the aggregate prepayment amount, notional amount or other similar amount (each howsoever defined) for any such transactions at any one time outstanding does not exceed 10% of the market capitalization of Counterparty immediately prior to the entry into such transaction, as commercially reasonably determined by the Calculation Agent.

Notwithstanding the foregoing and “Consequences of Merger Events / Tender Offers” below:

(i) if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section [ ] of the Indenture, Section [ ] of the Indenture or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will, in good faith and in a commercially reasonable manner, determine the adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner;

(ii) in connection with any Potential Adjustment Event as a result of an event or condition set forth in Section [ ] of the Indenture or Section [ ] of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section [ ] of the Indenture) or “SP” (as such term is used in Section [ ] of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent shall, in good faith and in a commercially reasonable manner, have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities, with such adjustments made assuming that Dealer maintains commercially reasonable hedge positions, as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

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


		activities, with such adjustments made assuming that Dealer maintains commercially reasonable hedge positions, as a result of such Potential Adjustment Event Change.

Dilution Adjustment Provisions:		Sections [ ] of the Indenture.

Extraordinary Events:

New Shares:		In the definition of New Shares in Section 12.1(i) of the Equity Definitions, (a) the text in clause (i) thereof shall be deleted in its entirety and replaced with “publicly quoted, traded or listed on any of The New York Stock Exchange, The NASDAQ Global Market or The NASDAQ Global Select Market (or their respective successors),” and (b) the following phrase shall be inserted immediately prior to the period: “and (iii) of a corporation organized under the laws of the United States, any State thereof or the District of Columbia that (x) also becomes the Counterparty under the Transaction or (y) agrees to be subject to Sections 8(d) and 8(e) of the Confirmation governing the Transaction, in either case, following such Merger Event or Tender Offer”.

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

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

Consequences of Merger Events / Tender Offers:		Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence of a Merger Event or a Tender Offer, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction, subject to the second paragraph under “Method of Adjustment”; provided, however, that such adjustment shall be made without regard to any adjustment to the “Conversion Rate” (as defined in the Indenture) pursuant to any Excluded Provision; provided further that if, with respect to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any State thereof or the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender Offer will not be a corporation organized under the laws of the United States, any State thereof or the District of Columbia, then, in either case, Cancellation and Payment (Calculation Agent Determination) may apply at Dealer’s reasonable election; provided further that, for the avoidance of doubt, adjustments shall be made pursuant to the provisions set forth above regardless of whether any Merger Event or Tender Offer gives rise to an Early Conversion.


Consequences of Announcement Events:		Modified Calculation Agent Adjustment as set forth in Section 12.3(d) of the Equity Definitions; provided that, in respect of an Announcement Event, (x) references to “Tender Offer” shall be replaced by 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 set forth in Section 12.3(d) shall be replaced with the phrase “Cap Price (provided that in no event shall the Cap Price be less than the Strike Price)” and the words “whether within a commercially reasonable (as 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 in 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 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 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 or a Valid Third Party Entity) of any transaction or event that is reasonably likely to be completed and, if completed, Merger Event or Tender Offer, or the announcement by Counterparty of any intention to enter into 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 the effect of the relevant announcement on the Shares and/or options relating to the Shares and, if such effect is material, shall deem such transaction or event to be reasonably likely to be completed, (ii) the public announcement (whether by Counterparty or a Valid Third Party Entity) 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 (whether by Counterparty or a Valid Third Party Entity) of an intention


		by Counterparty or such Valid Third Party Entity 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 (whether by Counterparty or a Valid Third Party Entity) 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); provided that, 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.

Valid Third Party Entity:		In respect of any transaction any third party that has an intent to enter into or consummate such transaction whose announcement is reasonably determined by the Calculation Agent to have had a material economic effect (as reasonably determined by the Calculation Agent) 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.

Additional Disruption Events:

(a) Change in Law:		Applicable; provided that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or public announcement of, the formal interpretation”, (ii) by adding the phrase “and/or type of Hedge Position that would be entered into by a commercially reasonable dealer” after the word “Shares” in clause (X) thereof and (iii) by immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by the Hedging Party on the Trade Date assuming the dealer maintains a commercially reasonable hedge position.”

Dealer to purchase or sell Shares or enter into swap or other derivatives transactions with respect to Shares in connection with its 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; provided that in no event shall the Expiration Date be postponed by more than 60 Scheduled Trading Days.

(b) Additional Termination Events.

(i) Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion in respect of which a notice of conversion that is effective as to Counterparty has been delivered by the relevant converting “Holder” (as such term is defined in the Indenture):

(A)

Counterparty shall, within five Scheduled Trading Days of the Conversion Date for such Early Conversion, provide written notice (an “Early Conversion Notice”) to Dealer specifying the number of Convertible Notes surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), and the giving of such Early Conversion Notice shall constitute an Additional Termination Event as provided in this clause (i);

(B)

upon receipt of any such Early Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related settlement date for such Affected Convertible Notes) with respect to the portion of the Transaction corresponding to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) the number of Affected Convertible Notes [minus the “Affected Number of Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Affected Convertible Notes]¹⁸ and (y) the Number of Options as of the Conversion Date for such Early Conversion;

(C)

any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided that the amount payable with respect to such termination shall not be greater than (1) the Applicable Percentage, multiplied by (2) the Affected Number of Options, multiplied by (3) (x) the sum, per each USD 1,000 principal amount of an Affected Convertible Note, of (i) the amount of cash paid to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the number of Shares, if any, delivered to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note, multiplied by the Applicable Limit Price on the settlement date for the conversion of such Affected Convertible Note (the “Unwind Date”), minus (y) the Synthetic Instrument Adjusted Issue Price on the Unwind Date, as determined by the Calculation Agent in good faith and in a commercially reasonable manner. “Synthetic Instrument Adjusted Issue Price” shall mean the amount determined by the Calculation Agent by reference to the table set forth below (the “Synthetic Instrument AIP Table”).

(D)

for the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction pursuant to Section 6 of the Agreement, the Calculation Agent shall assume that (x) the relevant Early Conversion and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (y) no adjustments to the “Conversion Rate” (as defined in the Indenture) have occurred pursuant to any Excluded Provision and (z) the corresponding Convertible Notes remain outstanding as if the circumstances related to such Early Conversion had not occurred; and

Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section 8(b)(ii). Upon receipt of any such Repayment Notice, Dealer shall promptly designate an Exchange Business Day following receipt of such Repayment Notice (which in no event shall be earlier than the related settlement date for the relevant Repayment Event) as an Early Termination Date with respect to the portion of the Transaction corresponding to a number of Options (the “Repayment Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repayment Notice [minus the number of Repayment Options (as defined in the Base Call Option 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 Confirmation will be among the

Any payment hereunder with respect to such termination (the “Repayment Unwind Payment”) shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Repayment Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event, (3) the terminated portion of the Transaction were the sole Affected Transaction, (4) the relevant Repayment Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (5) no adjustments to the “Conversion Rate” (as defined in the Indenture) have occurred pursuant to any Excluded Provision and (6) the corresponding Convertible Notes remain outstanding as if the circumstances related to such Repayment Event had not occurred; provided that, in the event of a Repayment Event pursuant to Section [ ] of the Indenture or Section [ ] of the Indenture, the Repayment Unwind Payment shall not be greater than (x) the number of Repayment Options multiplied by (y) the product of (A) the Applicable Percentage and (B) the excess of (I) the amount paid by the Counterparty per Convertible Note in connection with the relevant Repayment Event pursuant to the relevant sections of the Indenture over (II) the Synthetic Instrument Adjusted Issue Price determined by the Calculation Agent in a commercially reasonable manner based on the date of payment of the amount due to the holders of relevant Convertible Notes subject to such Repayment Event (the “Repayment Date”). If the relevant Repayment Date is not listed in the Synthetic Instrument AIP Table, the amount in the preceding sentence shall be determined by the Calculation Agent by reference to the Synthetic Instrument AIP Table, using a linear interpolation between the lower and higher Synthetic Instrument Adjusted Issue Prices for the Repayment Dates immediately preceding and immediately following the relevant Repayment Date. “Repayment Event” means that (i) any Convertible Notes are repurchased (whether pursuant to Section [ ] of the Indenture or Section [ ] of the Indenture or otherwise) by Counterparty or any of its subsidiaries (including in connection with, or as a result of, a “Fundamental Change” (as defined in the Indenture), a redemption, a tender offer, exchange offer or similar transaction or for any other reason), (ii) any Convertible Notes are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (iii) any principal of any of the Convertible Notes is repaid in full prior to the final maturity date of the Convertible Notes (other than upon acceleration of the Convertible Notes pursuant to Section [ ] of the Indenture), or (iv) any Convertible Notes are exchanged by or for the benefit of the “Holders” (as such term is defined in the Indenture) thereof for any other securities of Counterparty or any of its affiliates (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction. For the avoidance of doubt, any conversion of Convertible Notes (whether into cash, Shares, a combination of cash and Shares or any “Reference Property” (as defined in the Indenture)) pursuant to the terms of the Indenture shall not constitute a Repayment Event. Counterparty acknowledges and agrees that if an Additional Termination Event has occurred under this Section 8(b)(ii), then any related Convertible Notes subject to a Repayment Event will be deemed to be cancelled and disregarded and no longer outstanding for all purposes hereunder.

(iii) Notwithstanding anything to the contrary in this Confirmation, the occurrence of an event of default with respect to Counterparty under the terms of the Convertible Notes as set forth in Section [ ] of the Indenture, which default has resulted in the Convertible Notes becoming due and payable under the terms thereof, 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.

(iv) Notwithstanding anything to the contrary in this Confirmation, if a Repayment Event in respect of Convertible Notes occurs but an Additional Termination Event does not occur in respect of such Repayment Event under Section 8(b)(ii), then for all purposes hereunder, the Indenture and such Convertible Notes shall be deemed to remain outstanding regardless of whether such Convertible Notes are actually outstanding following such Repayment Event.

²³	Include for Additional Call Option Confirmation.

(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) an Announcement Event, 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 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

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 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); 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.

(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). 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 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 commercially reasonable expenses (including commercially 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.

(i) Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to the following conditions:

(A)

With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 8(e) or any obligations under (x) Section 8(d) of this Confirmation or (y) in respect of any Extraordinary Event occurring prior to such transfer;

(B)

Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended (the “Code”));

(C)

Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as are requested and reasonably satisfactory to Dealer;

(D)

Dealer will not, as a result of such transfer or assignment, be required to pay or deliver to the transferee or assignee on any payment date an amount of cash or number of Shares, as applicable, (after accounting for amounts payable by Dealer to the transferee or assignee under Section 2(d)(i)(4) of the Agreement) greater than an amount of cash or number of Shares, as applicable, that Dealer would have been required to pay to Counterparty in the absence of such transfer or assignment;

(E)

Dealer will not, as a result of such transfer or assignment, receive from the transferee or assignee on any payment (after accounting for amounts paid by the transferee or assignee under Section 2(d)(i)(4) of the Agreement) an amount less than the amount it would have been entitled to receive from Counterparty 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 cause the transferee or assignee to make such Payee Tax Representations and to provide a complete and accurate U.S. Internal Revenue Service Form W-9 (or successor thereto) and any such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described inclauses (D) and (E) will not occur upon or after such transfer or assignment; and

(H)

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

(ii) Dealer may, without Counterparty’s consent, transfer or assign all, but not less than all, of its rights or obligations under the Transaction to any Affiliate or branch of Dealer that (i) is a nationally recognized dealer in equity derivatives similar to the Transaction and (ii) 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 if the following conditions are satisfied (the “Transfer Conditions”): (1) the transferee agrees in writing with Dealer to be bound by the terms of this Confirmation with respect to the transferred obligations; (2) as of the date of such transfer, and giving effect thereto, the transferee will not be required to withhold or deduct on account of an Indemnifiable Tax from any payments under the Agreement (except to the extent such additional amount is required as a result of a change in law after the date of such transfer) or will be required to gross up for such Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement; (3) as of the date of such transfer, and giving effect thereto, Counterparty will not be required to gross up for such Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement (except to the extent such payment is required as a result of a change in law after the date of such transfer); (4) the transferee or assignee shall make such Payee Tax Representations as may be reasonably requested by Counterparty and provide Counterparty with a complete and accurate, as applicable, U.S. Internal Revenue Service Form W-9 or W-8 (or successor thereto) on or prior to becoming a party to the Transaction; (5) no Event of Default where Dealer is the Defaulting Party or Termination Event where Dealer is the sole Affected Party has occurred and is continuing at the time of the transfer, and no Event of Default or Termination Event will occur with respect to Counterparty, Dealer or the transferee as a result of such transfer; (6) if to a transferee incorporated or organized in a jurisdiction other than the United States or United Kingdom, after giving effect to such transfer, no material adverse legal or regulatory consequence shall result to Dealer, Counterparty or the transferee as a result of such transfer; [and] (7) Dealer shall have provided prompt written notice to Counterparty of such transfer[; and (8) the Guarantor agrees to guarantee any obligations of the transferee hereunder]. Dealer may, with Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any other third party, such consent not to be unreasonably withheld or delayed. If at any time at which (A) the Section 16 Percentage exceeds 9.0%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 8(c) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number

of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

(iii) Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance, but shall not be discharged to the extent of any failure to perform any designated or delegated obligation of Dealer under this Confirmation.

(g) Staggered Settlement. If upon the advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities hereunder, Dealer determines reasonably and in good faith that it would have a legal or regulatory concern if it were to deliver, or to acquire Shares to deliver, any or all of Shares required to be delivered to Counterparty hereunder on any Settlement Date, then Dealer may, acting in good faith and in a commercially reasonable manner, 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 20^th Exchange Business Day after 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 [“Firm Securities”]²⁴ [“Optional Securities”]²⁵ (as defined in the Purchase Agreement dated as of November 6, 2025, between Counterparty and BofA Securities, Inc. and Morgan Stanley & Co. LLC, 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 third Business Day following 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) and (iv), such adjustments will be made solely to account for the dilutive or concentrative effect of such event on 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), (v), (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.”; and

(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”.

(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 or determination of any amount 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 relating to the Transaction.

(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.

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