Re: [Base][Additional] Call Option Transaction

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the call option transaction entered into between [_________] (“Dealer”) and Everbridge, Inc. (“Counterparty”) as of the Trade Date specified below (the “Transaction”). This letter agreement constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below. Each party further agrees that this Confirmation together with the Agreement evidence a complete binding agreement between Counterparty and Dealer as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. In the event of any inconsistency between the Equity Definitions and this Confirmation, this Confirmation shall govern. Certain defined terms used herein are based on terms that are defined in the Preliminary Offering Memorandum dated March [__], 2021 (the “Offering Memorandum”) relating to the [___]% Convertible Senior Notes due 2026 (the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) as originally issued by Counterparty pursuant to the Purchase Agreement (as defined herein) and pursuant to an Indenture [to be]² dated March [__], 2021 (the “Indenture”). In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation. The parties further acknowledge that the Indenture section numbers used herein are based on the [draft of the Indenture last reviewed by Dealer and the Counterparty 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]³[Indenture as executed]⁴. Subject to the foregoing, references to the Indenture herein are references to the Indenture in effect on the date of its execution, and if the Indenture is amended or supplemented following such date (other than any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 14.07(a) of the Indenture, subject, in the case of this clause (y), to the second paragraph under “Method of Adjustment” in Section 3), any such amendment or supplement will be disregarded for purposes of this Confirmation (other than as provided in Section 9(h)(iv) below) unless the parties agree otherwise in writing. For purposes of the Equity Definitions, the Transaction shall be deemed to be a Share Option Transaction.

If Dealer, the Calculation Agent or the Determining Party is required to make any calculation, adjustment or determination hereunder by reference to the Convertible Notes or the Indenture at a time at which the Convertible Notes are no longer outstanding, Dealer, the Calculation Agent or the Determining Party, as the case may be, shall make such calculation, adjustment or determination, as applicable, assuming the Convertible Notes remained outstanding.

Each party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial financial transactions and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this Confirmation relates on the terms and conditions set forth below.

1. This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Dealer and Counterparty had executed an agreement in such form on the Trade Date but without any Schedule except for:

(a) the election of the laws of the State of New York as the governing law (without reference to choice of law doctrine) and the election of USD as the Termination Currency;

[[(b)] the election of (i) 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, and (ii) Guarantor as Credit Support Provider in relation to Dealer;]⁵

[(b)(c)] (i) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Dealer with a “Threshold Amount” of three percent of the shareholders’ equity of [Dealer][Dealer’s ultimate parent] as of the Trade Date; provided that “Specified Indebtedness” shall not include obligations in respect of deposits received in the ordinary course of Dealer’s banking business, (ii) the phrase “or becoming capable at such time of being declared” shall be deleted from clause (1) of such Section 5(a)(vi) and (iii) the following language shall be added to the end thereof “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (x) the default was caused solely by error or omission of an administrative or operational nature; (y) funds were available to enable the party to make the payment when due; and (z) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay.”; and

[(c)(d)] following the payment of the Premium, the condition precedent in Section 2(a)(iii) of the Agreement with respect to Events of Default or Potential Events of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) shall not apply to a payment or delivery owing by Dealer to Counterparty.

In the event of any inconsistency between provisions of the Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this Confirmation relates. The parties hereby agree that no transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement. 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.

3.  Additional Terms applicable to the Transaction.

For the avoidance of doubt, Dealer shall not

Page 7 of 32

		have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 14.04(c) of the Indenture or the fourth sentence of Section 14.04(d) of the Indenture).
Method of Adjustment:		Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions (which Section shall not apply for purposes of the Transaction except as provided in Section 9(x) below), upon any Potential Adjustment Event, the Calculation Agent shall make an adjustment to the Strike Price and the Option Entitlement corresponding to the adjustment required to be made pursuant to the Indenture to the “Conversion Rate” (as such term is defined in the Indenture).
		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 14.05 of the Indenture, Section 14.07 of the Indenture or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will determine in good faith and in a commercially reasonable manner the adjustment to be made to any one or more of the Strike Price, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner; provided that, notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the Indenture because the relevant Holder (as such term is defined in the Indenture) was deemed to be a record owner of the underlying Shares on the related Conversion Date, then the Calculation Agent shall make a commercially reasonable adjustment, as determined by it, to the terms hereof in order to account for such Potential Adjustment Event;

Page 8 of 32

		(ii)  in connection with any Potential Adjustment Event as a result of an event or condition set forth in Section 14.04(b) of the Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such term is used in Section 14.04(b) of the Indenture) or “SP0” (as such term is used in Section 14.04(c) of the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such Potential Adjustment Event, then the Calculation Agent shall have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the commercially reasonable costs (to account solely for hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities with respect to the Transaction, 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 have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the commercially reasonable costs (to account solely for hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities with respect to the Transaction, 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 14.04(a), (b), (c), (d) and (e) and Section 14.05 of the Indenture.

Consequences of Merger Events/Tender Offers:		Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions (which Section shall not apply for purposes of the Transaction except as provided in Section 9(x) below), upon the occurrence of a Merger Event or a Tender Offer, the Calculation Agent shall make a corresponding adjustment to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction to the extent that an analogous adjustment is required to be made pursuant to the Indenture in respect of such Merger Event or Tender Offer, subject to the second paragraph under “Method of Adjustment”; provided, however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to any Excluded Provision; provided further that if, with respect to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any State thereof or the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender Offer will not be a corporation 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 sole 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 results in a Conversion Date occurring prior to the Free Convertibility Date (any such conversion, 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”, (y) the phrase “exercise, settlement, payment or any other terms of the Transaction (including, without limitation, the spread)” 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

Page 10 of 32

		(as determined 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 determine whether the relevant Announcement Event has had a material economic effect on the Transaction (and, if so, may adjust the Cap Price accordingly) 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 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; provided that in no event shall the Cap Price be adjusted to be less than the Strike Price. An Announcement Event shall be an “Extraordinary Event” for purposes of the Equity Definitions, to which Article 12 of the Equity Definitions is applicable.
Announcement Event:		(i) The public announcement by (x) any entity 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 may take into consideration the effect of the relevant announcement on the Shares and/or options relating to the Shares), (y) Issuer or any subsidiary thereof of any potential acquisition or disposition by Issuer and/or its subsidiaries where the aggregate consideration exceeds 35% of the market capitalization of Issuer as of the date of such announcement (an “Acquisition Transaction”) or (z) Issuer, any subsidiary of Issuer or any Valid Third-Party Entity of the bona fide intention to enter into a Merger Event or Tender Offer or an Acquisition Transaction (in the case of a Valid Third-Party Entity, that the Calculation Agent determines is capable, financially and otherwise, of consummating the relevant Merger Event, Tender Offer or Acquisition Transaction, it being understood and agreed that in making such determination, the Calculation Agent may take into consideration the effect of the relevant announcement on the Shares and/or options relating to the Shares), (ii) the public announcement by Issuer of an intention to solicit or enter into, or to explore strategic alternatives or other similar undertaking that may include, a Merger Event or Tender Offer or an Acquisition Transaction or (iii) any subsequent public announcement by any entity of a change to a transaction or intention that is the subject of an announcement of the type described in clause (i) or (ii) of this sentence (including, without limitation, a new announcement, whether or not by the same party, relating

Page 11 of 32

		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. 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,” (A) “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) and (B) “Tender Offer” shall mean such term as defined under Section 12.1(d) of the Equity Definitions; provided that Section 12.1(d) of the Equity Definitions is hereby amended by replacing “10%” with “20%” in the third line thereof.
Valid Third-Party Entity:		In respect of any transaction, any third party that the Calculation Agent determines has a bona fide intent to enter into or consummate such transaction (it being understood and agreed that in determining whether such third party has such a bona fide intent, the Calculation Agent may take into consideration the effect of the relevant announcement by such third party on the Shares and/or options relating to the Shares).
Nationalization, Insolvency or Delisting:		Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the Exchange.
Additional Disruption Events:
Change in Law:		Applicable; provided that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or public announcement of, the formal or informal interpretation”, (ii) replacing the word “Shares” where it appears in clause (X) thereof with the words “Hedge Position”, (iii) replacing the parenthetical beginning after the word “regulation” in the second line thereof the words “(including, for the avoidance of doubt and without limitation, (x) any tax law or (y) adoption, effectiveness or promulgation of new regulations

Page 12 of 32

		authorized or mandated by existing statute)” and (iv) adding the words “provided that, in the case of clause (Y) hereof and any law, regulation or interpretation, the consequence of such law, regulation or 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.
Failure to Deliver:		Applicable

Increased Cost of Hedging:		Not Applicable
Hedging Party:		For all applicable Additional Disruption Events, Dealer.
Determining Party:		For all applicable Extraordinary Events, Dealer; provided that when making any determination or calculation as “Determining Party,” Dealer shall be bound by the same obligations relating to required acts of the Calculation Agent as set forth in Section 1.40 of the Equity Definitions and this Confirmation as if Determining Party were the Calculation Agent.
		Following any determination or calculation by Determining Party hereunder, upon a written request by Counterparty (which may be by email), Determining Party will promptly (but in any event within three Scheduled Trading Days) provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such determination or calculation (including any assumptions used in making such determination or calculation), it being understood that in no event will Determining Party be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it in making such determination or calculation or any information that is subject to an obligation not to disclose such information.

(b) In lieu of the representation set forth in Section 3(a)(iii) of the Agreement, neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of Counterparty hereunder will conflict with or result in a breach of the certificate of incorporation or by-laws (or any equivalent documents) of Counterparty, or any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental authority or agency, or any agreement or instrument filed as an exhibit to Counterparty’s Annual Report on Form 10-K for the year ended December 31, 2020 (other than agreements or instruments filed as exhibits pursuant to Item 601(b)(10)(iii) of Regulations S-K under the Securities Act), in each case to which Counterparty or any of its subsidiaries is a party or by which Counterparty or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under, or result in the creation of any lien under, any such agreement or instrument.

(c) No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws.

(d) Counterparty is not and, after consummation of the transactions contemplated hereby, will not be required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

(e) On and immediately after the Trade Date and the Premium Payment Date, (A) the value of the total assets of Counterparty is greater than the sum of the total liabilities (including contingent liabilities) and the capital (as such terms are defined in Section 154 and Section 244 of the General Corporation Law of the State of Delaware) of Counterparty, (B) the capital of Counterparty is adequate to conduct the business of Counterparty, and Counterparty’s entry into the Transaction will not impair its capital, (C) Counterparty has the ability to pay its debts and obligations as such debts mature and does not intend to, or does not believe that it will, incur debt beyond its ability to pay as such debts mature, (D) Counterparty is not “insolvent” (as such term is defined under Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)) and (E) Counterparty would be able to purchase the number of Shares with respect to the Transaction in compliance with the laws of the jurisdiction of Counterparty’s incorporation (including the adequate surplus and capital requirements of Sections 154 and 160 of the General Corporation Law of the State of Delaware).

(f) Counterparty is not, on the date hereof, aware of any material non-public information with respect to Counterparty or the Shares.

(g) To the knowledge of Counterparty, no state or local (including any non-U.S. jurisdiction’s) law, rule, regulation or regulatory order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) as a result of Dealer or its affiliates owning or holding (however defined) Shares; provided that Counterparty makes no representation or warranty regarding any such requirement that is applicable generally to the ownership of equity securities by Dealer or any of its affiliates solely as a result of it or any of such affiliates being a financial institution or broker-dealer.

(h) Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least USD 50 million as of the date hereof.

(j) Counterparty represents and warrants that neither it nor any of its subsidiaries has applied, has any present intention to apply and, prior to the termination or settlement of the Transaction, has any intention to apply, for a loan, loan guarantee, direct loan (as that term is defined in the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”)) or other investment, or to receive any financial assistance or relief under any program or facility (collectively “Financial Assistance”) 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) (i) requires under applicable law (or any regulation, guidance, interpretation or other pronouncement of a governmental authority with

Page 16 of 32

jurisdiction for such program or facility) as a condition of such Financial Assistance, that the Counterparty comply with any requirement not to, or otherwise 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, and that Counterparty has not, as of the date specified in the condition, made a capital distribution or will make a capital distribution, or (ii) where the terms of the Transaction would cause Counterparty to fail to satisfy any condition for application for or receipt or retention of the Financial Assistance (collectively “Restricted Financial Assistance”).

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, and is entering into the Transaction as principal (and not as agent or in any other capacity, fiduciary or otherwise) and not for the benefit of any third party.

9. Other Provisions.

(a) Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Premium Payment Date, with respect to the matters set forth in Sections 8(a)(i) and (ii), 8(b) and 8(c) (as to agreements governing indebtedness) of this Confirmation (it being understood that such opinions of counsel shall be limited to the federal laws of the United States, the laws of the State of New York and the General Corporate Law of the State of Delaware and may contain customary limitations, exceptions and qualifications). Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement.

(b) Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than [__]¹⁰ million (in the case of the first such notice) or (ii) thereafter more than [__]¹¹ million less than the number of Shares included in the immediately preceding Repurchase Notice; provided that Counterparty may provide Dealer advance notice on or prior to any such day to the extent it expects that repurchases effected on such day may result in an obligation to deliver a Repurchase Notice (and in such case, any such advance notice shall be deemed a Repurchase Notice to the maximum extent of repurchases set forth in such advance notice as if Counterparty had executed such repurchases). Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging activities, assuming Dealer maintains a commercially reasonable hedge with respect to the Transaction, as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from such hedging activities or cessation of such hedging activities and any commercially reasonable losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and reasonable and documented out-of-pocket expenses (including reasonable attorney’s fees of one outside counsel in each relevant jurisdiction), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other out-of-pocket expenses incurred (and supported by invoices or other documentation setting forth in reasonable detail such expenses) in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the

¹⁰  Insert the number of Shares outstanding that would cause Dealer’s current position in the Shares underlying the Transaction, plus the number of Shares underlying any additional transaction (assuming the greenshoe is exercised in full), plus the full number of Shares under the Counterparty’s 2017 and 2019 capped call transactions to increase by 0.5%. To be based on Dealer with the highest number of Shares underlying the Transaction, any additional transaction (assuming the greenshoe is exercised in full) and the 2017 and 2019 capped call transactions.

¹¹  Insert the number of Shares that, if repurchased, would cause Dealer’s current position in the Shares underlying the Transaction plus the number of Shares underlying any additional transaction (assuming the greenshoe is exercised in full), plus the full number of Shares under the Counterparty’s 2017 and 2019 capped call transactions to increase by a further 0.5% from the threshold for the first Repurchase Notice. To be based on Dealer with the highest number of Shares underlying the Transaction, any additional transaction (assuming the greenshoe is exercised in full) and the 2017 and 2019 capped call transactions.

foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable to the extent that the Indemnified Person fails to notify Counterparty within a commercially reasonable period of time after any action is commenced against it in respect of which indemnity may be sought hereunder. In addition, Counterparty shall not have liability for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any such proceeding contemplated by this paragraph that is pending or threatened in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. Counterparty shall not be liable for any losses, claims, damages or liabilities (or expenses relating thereto) of any Indemnified Person that result from the bad faith, gross negligence, willful misconduct or fraud of such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

(c) Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of any securities of Counterparty, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any such distribution.

(d) No Manipulation. Counterparty is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.

(e) Transfer or Assignment.

(i) Counterparty shall have the right to transfer or assign all or any of its rights and obligations hereunder with respect to all or any of the Options hereunder (such Options, the “Transfer Options”); provided that such transfer or assignment shall be subject to the following conditions:

(A) With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 9(b) or any obligations under Section 9(n) of this Confirmation;

Page 18 of 32

(B) 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 reasonably requested and reasonably satisfactory to Dealer;

(C) Dealer will not, as a result of such transfer or assignment, be required to pay the transferee or assignee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer or assignment;

(D) An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer or assignment;

(E) Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (C) and (D) will not occur upon or after such transfer or assignment, including but not limited to providing tax documentation specified in Section 9(aa) of this Confirmation and making the tax representations specified in Section 9(dd) of this Confirmation on or prior to such transfer and at the other times specified in such Sections; and

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

The foregoing requirements shall not apply to any pledge or grant of a security interest by Counterparty in its property, and notwithstanding herein shall be deemed to limit or prohibit the Counterparty from pledging or otherwise granting a security interest in, its rights, title and interests in its property in connection with any secured financing by the Counterparty or its affiliates.

(ii) Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (A) without Counterparty’s consent, to any affiliate of Dealer (1) that has a long-term issuer rating that is equal to or better than Dealer’s credit rating at the time of such transfer or assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by Dealer or Dealer’s ultimate parent entity (provided that in connection with any assignment or transfer pursuant to clause (A)(2) hereof, the guarantee of any guarantor of the relevant transferee’s obligations under the Transaction shall constitute a Credit Support Document under the Agreement), or (B) with Counterparty’s consent (such consent not to be unreasonably withheld or delayed), to any third party financial institution that is a recognized dealer in the market for U.S. corporate equity derivatives and that has a long-term issuer rating equal to or better than the lesser of (1) the credit rating of Dealer at the time of the transfer and (2) A- by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”), or A3 by Xxxxx’x Investor Service, Inc. or its successor (“Moody’s”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that, in the case of any transfer or assignment described in clause (A) or (B) above, (I) an Event of Default, Potential Event of Default or Termination Event will not occur as a result of such transfer and assignment, (II) Counterparty will not receive from the transferee or assignee on any payment date or delivery date 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, (III) Counterparty

Page 19 of 32

will not, as a result of such transfer or assignment, be required to pay the transferee or assignee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Counterparty would have been required to pay to Dealer in the absence of such transfer or assignment, and (IV) Dealer shall cause the transferee or assignee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Counterparty to permit Counterparty to determine that events described in clauses (II) and (III) of this proviso will not occur upon or after such transfer or assignment. 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 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). Dealer shall notify Counterparty of an Excess Ownership Position with respect to which it intends to seek a transfer or assignment as soon as reasonably practicable after becoming aware of such an Excess Ownership Position. 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 other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person (except for filings of Form 13F, Schedule 13D or Schedule 13G under the Exchange Act), or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

Page 20 of 32

(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 (and only to) the extent of any such performance.

(f) Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s commercially reasonable hedging activities hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows:

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

(ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; and

(iii) if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case may be, will apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above.

(g) [Role of Agent.]¹²[Insert relevant Dealer language regarding agency or communications with employees .]

(h) Additional Termination Events.

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

(A) Counterparty may, within ten Scheduled Trading Days of the “Conversion Date” (as defined in the Indenture) 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 anticipated settlement date, and the giving of such Early Conversion Notice shall constitute an Additional Termination Event as provided in this clause (i); provided that any such Early Conversion Notice shall contain a written representation by Counterparty to Dealer that Counterparty is not, on the date of such Early Conversion Notice, in possession of any material nonpublic information with respect to Counterparty or the Shares; provided further that the provisions of this Section 9(h)(i) shall not apply to any Affected Convertible Note (i) with respect to which Counterparty has elected the “Exchange in Lieu of Conversion” option pursuant to Section 14.12 of the Indenture and (ii) that has been accepted by the designated financial institution pursuant to Section 14.12 of the

¹²  Include for Dealer.

Page 21 of 32

Indenture, except to the extent that Counterparty notifies Dealer, within ten Scheduled Trading Days of the then applicable conversion settlement date determined pursuant to Section 14.02(i) of the Indenture, that (x) such financial institution has failed to pay or deliver, as the case may be, the consideration due upon conversion of such Affected Convertible Note, or (y) such Affected Convertible Note is subsequently resubmitted to Counterparty for conversion in accordance with the terms of the Indenture;

(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 conversion settlement date for such Early Conversion) 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 letter agreement dated March [__], 2021 between Dealer and Counterparty (the “Base Call Option Confirmation”), if any, that relate to such Affected Convertible Notes]¹³ 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 (and, for the avoidance of doubt, the provisions of Section 9(l) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this Section 9(h)(i) as if Counterparty were not the Affected Party);

(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 have occurred pursuant to any Excluded Provision and (z) the corresponding Convertible Notes remain outstanding; and

(E) the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such Early Conversion, the Number of Options shall be reduced by the Affected Number of Options.

(ii) Within ten Scheduled Trading Days following any Repurchase Event (as defined below), Counterparty may notify Dealer of such Repurchase Event and the aggregate principal amount of Convertible Notes subject to such Repurchase Event (any such notice, a “Convertible Notes Repurchase Notice”); provided that any such Convertible Notes Repurchase Notice shall contain a written representation by Counterparty to Dealer that Counterparty is not, on the date of such Convertible Notes Repurchase Notice, in possession of any material nonpublic information with respect to Counterparty or the Shares. The receipt by Dealer from Counterparty of any Convertible Notes Repurchase Notice shall constitute an Additional Termination Event as provided in this Section 9(h)(ii). Upon receipt of any such Convertible Notes Repurchase Notice, Dealer shall designate an Exchange Business Day following receipt of such Convertible Notes Repurchase Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related repurchase settlement date for the relevant

Repurchase Event) as an Early Termination Date with respect to the portion of the Transaction corresponding to a number of Options (the “Repurchase Options”) equal to the lesser of (A) the aggregate principal amount of such Convertible Notes specified in such Convertible Notes Repurchase Notice, divided by USD 1,000 [minus (y) the number of Repurchase Options (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes]¹⁴, and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Repurchase Options. Any payment hereunder with respect to such termination (the “Repurchase 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 Repurchase Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event, (3) no adjustments to the Conversion Rate have occurred pursuant to an Excluded Provision, (4) the corresponding Convertible Notes remaining outstanding, (5) the relevant Repurchase and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred and (6) the terminated portion of the Transaction were the sole Affected Transaction. “Repurchase Event” means that (i) any Convertible Notes are repurchased or redeemed (whether pursuant to Section 15.02 of the Indenture, Section 16.02 of the Indenture or otherwise) by Counterparty or any of its subsidiaries, (ii) any Convertible Notes are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the Convertible Notes (other than upon acceleration of the Convertible Notes described in Section 9(h)(iii)), or (iv) any Convertible Notes are exchanged by or for the benefit of the Holders (as defined in the Indenture) thereof for any other securities of Counterparty or any of its Affiliates (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction; provided that any conversion of Convertible Notes pursuant to the terms of the Indenture shall not constitute a Repurchase Event.

(iii) Notwithstanding anything to the contrary in this Confirmation if an event of default with respect to Counterparty occurs under the terms of the Convertible Notes as set forth in Section 6.01 of the Indenture and such event of default results in the Convertible Notes being accelerated and declared due and payable, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement (which Early Termination Date shall be on or as promptly as reasonably practicable after Dealer becomes aware of the occurrence of such acceleration).

(iv) Notwithstanding anything to the contrary in this Confirmation, the occurrence of an Amendment Event shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement. “Amendment Event” means that Counterparty amends, modifies, supplements, waives or obtains a waiver in respect of any term of the Indenture or the Convertible Notes governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, any term relating to conversion of the Convertible Notes (including changes to the conversion rate, conversion rate adjustment provisions, conversion settlement dates or conversion conditions), or any term that would require consent of the holders of not less than 100%

of the principal amount of the Convertible Notes to amend (other than, in each case, any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 14.07 of the Indenture), in each case, without the consent of Dealer.

(i) Amendments to Equity Definitions.

(i) Solely in respect of adjustments to the Cap Price pursuant to Section 9(x), Section 11.2(e)(vii) of the Equity Definitions is hereby amended by deleting the words “that may have a diluting or concentrative effect on the theoretical value of the relevant Shares” and replacing them with the words “that is the result of a corporate event involving the Issuer or its securities that has a material economic effect on the Shares or options on the Shares; provided that such event is not based on (a) an observable market, other than the market for the Company’s own stock or (b) an observable index, other than an index calculated and measured solely by reference to Company’s own operations.”

(ii) Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) inserting “(1)” immediately following the word “means” in the first line thereof and (2) inserting immediately prior to the semi-colon at the end of subsection (B) thereof the following words: “or (2) the occurrence of any of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer; provided that the period for dismissal, discharge, stay or restraint therein shall be increased from within 15 days to within 60 days”.

(iii) Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice to Counterparty” in the first sentence of such section.

(j) No Setoff. Neither party shall have the right to set off any obligation that it may have to the other party under the Transaction against any obligation such other party may have to it, whether arising under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of law or otherwise and each party hereby waives any such right to setoff.

(k) Adjustments. For the avoidance of doubt, whenever the Calculation Agent 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 (other than on adjustments made by reference to the Indenture), the Calculation Agent shall make such adjustment in a commercially reasonable manner by reference to the effect of such event on Dealer, assuming that Dealer maintains a commercially reasonable hedge position.

(l) 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 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 other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the date of

Page 24 of 32

the Announcement Event, Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not apply, (b) Counterparty remakes the representation set forth in Section 8(e) as of the date of such election 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 Section 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.
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. If such Naturalization, Insolvency, or Merger Event involves a choice of Exchange Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.
Failure to Deliver:		Applicable

Page 25 of 32

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 Share Termination Alternative is applicable to the Transaction.

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

(n) Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, based on the advice of counsel, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of effecting a commercially reasonable hedge of its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act and enter into an agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement customary for a registered secondary offering of a similar size in respect of a similar issuer; provided, however, that if Dealer, in its reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, use commercially reasonable efforts to enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities of a similar size in respect of a similar issuer, in form and substance commercially reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its commercially reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement; for the avoidance of doubt, any such adjustment shall take into account the illiquidity resulting from the fact that the Shares will not be registered for resale); 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 then held by Dealer from Dealer at the then current market price on such Exchange Business Days, and in the amounts and at such time(s), reasonably requested by Dealer.

(o) Tax Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax structure.

(p) Right to Extend. Dealer may postpone or add, in whole or in part, any Valid Day or Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by Dealer, with respect to some or all of the Options hereunder, if Dealer reasonably determines, in the case of clause (i), in its commercially reasonable judgment or, in the case of clause (ii), based on advice of counsel, that such action is reasonably necessary or appropriate (i) to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing

Page 26 of 32

liquidity conditions in the stock loan market or other relevant market (but only if there is a material decrease in liquidity relative to Dealer’s expectations on the Trade Date) or (ii) to enable Dealer to effect purchases of Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were the Issuer or an affiliated purchaser of the Issuer, be in compliance with applicable legal or regulatory, requirements of self-regulatory organizations with jurisdiction over Dealer or its affiliates, or with related policies and procedures adopted by Dealer in good faith so long as such policies and procedures would generally be applicable to counterparties similar to Counterparty and transactions similar to the Transaction); provided that no such Valid Day or other date of valuation, payment or delivery may be postponed or added more than 40 Valid Days after the original Valid Day or other date of valuation, payment or delivery, as the case may be.

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

(r) Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be a “securities contract” and a “swap agreement” as defined in the Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.

(s) Notice of Certain Other Events. Counterparty covenants and agrees that:

(i) promptly following the public announcement of the results of any election by the holders of Shares with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written notice of (x) the weighted average of the types and amounts of consideration that holders of Shares have elected to receive upon consummation of such Merger Event or (y) if no holders of Shares affirmatively make such election, the types and amounts of consideration actually received by holders of Shares (the date of such notification, the “Consideration Notification Date”); provided that in no event shall the Consideration Notification Date be later than the date on which such Merger Event is consummated; and

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

Counterparty understands, acknowledges and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Relevant Prices; and (D) any market activities of Dealer and its affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the Relevant Prices, each in a manner that may be adverse to Counterparty.

(v) Early Unwind. In the event the sale of the [“Underwritten Securities”]¹⁵[“Option Securities”]¹⁶ (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers for any reason, or Counterparty fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or such later date the “Early Unwind Date”), the Transaction shall automatically terminate (the “Early Unwind”), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date. 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.

(w) Payment by Counterparty. In the event that, following payment of the Premium, (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.

(x) Other Adjustments Pursuant to the Equity Definitions. Notwithstanding anything to the contrary in this Confirmation, solely for the purpose of adjusting the Cap Price, the terms “Potential Adjustment Event,” “Merger Event,” and “Tender Offer” shall each have the meanings assigned to such term in the Equity Definitions (as amended by Section 9(i)(i)) and the provisions modifying the term “Tender Offer” opposite the caption “Announcement Event” in Section 3 above), and upon the occurrence of a Merger Date, the occurrence of a Tender Offer Date, or declaration by Counterparty of the terms of any Potential Adjustment Event, respectively, as such terms are defined in the Equity Definitions, the Calculation Agent shall determine in a commercially reasonable manner whether such occurrence or declaration, as applicable, has had a material economic effect on the Transactions and, if so, may, in its commercially reasonable discretion, adjust the Cap Price to preserve the fair value of the Options; provided that in no event shall the Cap Price be less than the Strike Price; provided further that (i) any adjustment to the Cap Price made pursuant to this Section 9(x) shall be made without duplication of any other adjustment hereunder (including, for the avoidance of doubt, adjustment made pursuant to the provisions opposite the captions “Method of Adjustment,” “Consequences of Merger Events / Tender Offers” and “Consequence of Announcement Events” in Section 3 above).

(ii) Limitation on Exercise of Certain Default Rights Related to an Affiliate’s Entry Into Insolvency Proceedings. Notwithstanding anything to the contrary in this Confirmation, the parties expressly acknowledge and agree that:
