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 Ionis Pharmaceuticals, 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 Offering Memorandum dated [_______], 2021 (the “Offering Memorandum”) relating to the [__]% Convertible Senior Notes due 2026 (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 [500,000,000] (as increased by [up to]¹ an aggregate principal amount of USD [75,000,000] [if and to the extent that]²[pursuant to the exercise by]³ the Initial Purchasers (as defined herein) [exercise]⁴[of]⁵ their option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture (the “Indenture”) [to be]⁶ dated [_______], 2021 between Counterparty and U.S. Bank National Association, as trustee (the “Trustee”). 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 that 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 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]⁷[Indenture as executed]⁸. Subject to the foregoing, references to the Indenture herein are references to the Indenture as in effect on the date of its execution, and if the Indenture is amended or supplemented following such date, any such amendment or supplement (other than any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as reasonably determined by the Calculation Agent, conforms the Indenture to the

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.

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 (the “Agreement”) in the form of the 2002 ISDA Master Agreement as if Dealer and Counterparty had executed an agreement in such form on the date hereof (but without any Schedule except for (i) the election of US Dollars (“USD”) as the Termination Currency[, (ii) the election of an executed guarantee of [_______] (“Guarantor”) dated as of the Trade Date in substantially the form attached hereto as Annex A as a Credit Support Document, (iii) the designation of Guarantor as Credit Support Provider in relation to Dealer]⁹ and [(ii)][(iv)] (a) 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 [Name of Dealer’s Parent], (b) the phrase “or becoming capable at such time of being declared” shall be deleted from clause (1) of such Section 5(a)(vi), (c) 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 (d) the term “Specified Indebtedness” shall have the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect of deposits received in the ordinary course of Dealer’s banking business). 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. For the avoidance of doubt, except to the extent of an express conflict, the application of any provision of this Confirmation, the Agreement or the Equity Definitions shall not be construed to exclude or limit the application of any other provision of this Confirmation, the Agreement or the Equity Definitions. The Transaction hereunder shall be the sole Transaction under the Agreement. If there exists any ISDA Master Agreement between Dealer and Counterparty or any confirmation or other agreement between Dealer and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Dealer and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which Dealer and Counterparty are parties, the Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

		suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by such stock exchange or otherwise) in the Shares or in any options contracts or futures contracts on any Related Exchange relating to the Shares.”

Settlement Terms.

Settlement Method:		For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement Method, but only if Counterparty or Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) shall have notified Dealer of the Relevant Settlement Method in the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option. If the Trustee (or any other such agent) on behalf of Counterparty provides any such notice, Dealer shall be entitled to rely on the accuracy of such notice without any independent investigation, and the contents of such notice shall be binding on Counterparty. Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act (as defined below) and the rules and regulations thereunder, in respect of any election of a settlement method with respect to the related Convertible Notes.

Relevant Settlement Method:		In respect of any Option:

		(i) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note (A) entirely in Shares pursuant to Section 14.02(a)(iv)(A) of the Indenture (together with cash in lieu of fractional Shares) (such settlement method, “Settlement in Shares”) (B) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “Low Cash Combination Settlement”) or (C) in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Indenture with a Specified Cash Amount equal to USD 1,000 (such settlement method, “Par Cash Settlement”), then, for each of the cases in clause (A) (Settlement in Shares), clause (B) (Low Cash Combination Settlement) and clause (C) (Par Cash Settlement), the Relevant Settlement Method for such Option shall be Net Share Settlement;

		(ii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note in a combination of cash and Shares pursuant to Section 14.02(a)(iv)(C) of the Indenture with a Specified Cash Amount greater than USD 1,000, then the Relevant Settlement Method for such Option shall be Combination Settlement; and


		(iii) if Counterparty has elected to settle its conversion obligations in respect of the related Convertible Note entirely in cash pursuant to Section 14.02(a)(iv)(B) of the Indenture (such settlement method, “Settlement in Cash”), then the Relevant Settlement Method for such Option shall be Cash Settlement.

Net Share Settlement:		If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, a number of Shares (the “Net Share Settlement Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b) the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for such Option.

		Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Net Share Settlement Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

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. If any reduction is made to the delivery obligation hereunder as a result of the foregoing, such reduction shall first be made to any Combination Settlement Share Amount.

		Dealer will deliver cash in lieu of any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the 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 Relevant Price on such Valid Day 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.

Make-Whole Adjustment:		Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes in connection with a Make-Whole Fundamental Change (as defined in the Indenture) for which additional Shares will be added to the “Conversion Rate” (as defined in the Indenture) as determined pursuant to Section 14.03 of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the number of such additional Shares as determined with reference to the adjustment set forth in such Section 14.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any) deliverable by Dealer to


		Counterparty per exercised Option and (b) the Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the amount per Option, as determined by the Calculation Agent, that would be payable by Dealer under Section 6 of the Agreement if (x) the relevant Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction was the sole Affected Transaction and Counterparty was the sole Affected Party and (y) Section 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess, with such reduction first being made to any Shares deliverable hereunder.

Applicable Limit:		For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the sum of (A) the amount of cash, if any, payable to the Holder of the related Convertible Note upon conversion of such Convertible Note determined pursuant to Section 14.02(a)(iv) of the Indenture and (B) the number of Shares, if any, deliverable to the Holder of the related Convertible Note upon conversion of such Convertible Note determined pursuant to Section 14.02(a)(iv) of the Indenture multiplied by the Applicable Limit Price on the Settlement Date for such Option, over (ii) USD 1,000.

Applicable Limit Price:		On any day, the opening price as displayed under the heading “Op” on Bloomberg page IONS <equity> (or any successor thereto).

Valid Day:		A day on which (i) there is no Market Disruption Event and (ii) trading in the Shares generally occurs on The NASDAQ Global Select Market or, if the Shares are not then listed on The NASDAQ Global Select Market, on the principal other United States national or regional securities exchange on which the Shares are then listed or, if the Shares are not then listed on a United States national or regional securities exchange, on the principal other United States market on which the Shares are then listed or admitted for trading. If the Shares are not so listed or admitted for trading, “Valid Day” means a Business Day.

Scheduled Valid Day:		A day that is scheduled to be a Valid Day on the principal United States national or regional securities exchange or market on which the Shares are listed or admitted for trading. If the Shares are not so listed or admitted for trading, “Scheduled Valid Day” means a Business Day.

Business Day:		Any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York is authorized or required by law or executive order to close or be closed.


Relevant Price:		On any Valid Day, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page IONS <equity> AQR (or any successor thereto) in respect of the period from the scheduled opening time of the Exchange to the Scheduled Closing Time of the Exchange on such Valid Day (or if such volume-weighted average price is unavailable at such time, the market value of one Share on such Valid Day, as determined by the Calculation Agent in good faith and in a commercially reasonable manner using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after hours trading or any other trading outside of the regular trading session trading hours.

Settlement Averaging Period:		For any Option, and regardless of the Settlement Method applicable to such Option:

		(i) if the related Conversion Date occurs prior to the Free Convertibility Date, the 30 consecutive Valid Days commencing on, and including, the second Valid Day following such Conversion Date; or

Other Applicable Provisions:		To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9 and 9.11 of the Equity Definitions will be applicable, as if Physical Settlement applied to the Transaction.

Representation and Agreement:		Notwithstanding anything to the contrary in the Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to Counterparty shall, upon delivery, be subject to restrictions and limitations arising from Counterparty’s status as Issuer of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated form in lieu of delivery through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)). With respect to any such certificated Shares (as described in clause (ii) above), the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified


		by deleting the remainder of the provision after the word “encumbrance” in the fourth line thereof.

Adjustments applicable to the Transaction:

Potential Adjustment Events:		Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in any Dilution Adjustment Provision, that would result in an adjustment under the Indenture (as determined by the Calculation Agent by reference to the Dilution Adjustment Provisions) to the “Conversion Rate” or the composition of a “unit of Reference Property” or to any “Last Reported Sale Price”, “Daily VWAP,” “Daily Conversion Value” or “Daily Settlement Amount” (each as defined in the Indenture). For the avoidance of doubt, Dealer shall not 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 the first paragraph 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 (and, for the avoidance of doubt, in lieu of any adjustments pursuant to such Section), upon any Potential Adjustment Event, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment to the Convertible Notes under the Indenture to any one or more of the Strike Price, Number of Options, Option Entitlement, the composition of the Shares and any other variable relevant to the exercise, settlement or payment for the Transaction, as determined by reference to the Dilution Adjustment Provisions, to the extent an adjustment is required under the Indenture.

		Notwithstanding the foregoing:

		(i) if the Calculation Agent acting in good faith and in a commercially reasonable manner disagrees with any adjustment pursuant to the terms of the Indenture that is the basis of any adjustment hereunder and 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 the adjustment to be made to any one or more of the composition of the Shares, 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; provided that, notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Settlement Averaging Period but no adjustment is made 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 an adjustment, consistent with the methodology set forth in the Indenture, to the terms hereof in order to account for such Potential Adjustment Event;

		(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 adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the commercially reasonable costs and benefits (including, but not limited to, hedging mismatches and market gains and losses) and commercially reasonable gains and losses incurred by Dealer in connection with its commercially reasonable hedging activities (subject to the requirements set forth under Hedging Adjustments below) as a result of such event or condition not having been publicly announced prior to the beginning of such period; and

		(iii) if the terms of any Potential Adjustment Event are declared by Counterparty and (a) the event or condition giving rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned (whether or not there has been a “Conversion Rate”



		adjustment under the Indenture for such Potential Adjustment Event), (b) the “Conversion Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution Adjustment Provision other than pursuant to the fourth sentence of the first paragraph of Section 14.04(c) of the Indenture or the fourth sentence of Section 14.04(d) of the Indenture 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 such adjustment, in respect of such Potential Adjustment Event, is modified, amended, altered or corrected (each of clauses (a), (b) and (c), a “Potential Adjustment Event Change”) then, in each case, but without duplication, the Calculation Agent shall adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the commercially reasonable costs and benefits (including, but not limited to, commercially reasonable hedging mismatches and market gains and losses) and commercially reasonable gains and losses incurred by Dealer in connection with its commercially reasonable hedging activities (subject to the requirements set forth under Hedging Adjustments below) 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.

Extraordinary Events applicable to the Transaction:

Merger Events:		Applicable; provided that notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in the definition of “Share Exchange Event” in Section 14.07(a) 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 14.04(e) of the Indenture.

(c)

To Counterparty’s knowledge, no U.S. state or local law, rule, regulation or regulatory order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) as a result of Dealer or its affiliates owning or holding (however defined) Shares, other than any regulation that Dealer would be subject to as a result of its being a regulated entity under various applicable laws, including U.S. securities laws and FINRA.

(d)

Counterparty (i) is an “institutional account” as defined in FINRA Rule 4512(c); (ii) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities, and will exercise independent judgment in evaluating the recommendations of Dealer or its associated persons; and (iii) will notify Dealer if any of the statements contained in clause (i) or (ii) of this Section 8I(d) ceases to be true.

(e)

Without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that neither Dealer nor any of its affiliates is making any representations or warranties or taking any position or expressing any view with respect to the treatment of the Transaction under any accounting standards including ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, or ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity (or any successor issue statements).

(f)

Counterparty is not engaged in an “issuer tender offer” as such term is defined in Rule 13e-4 under the Exchange Act with respect to any Shares or any security convertible into or exchangeable or

exercisable for any Shares nor is it aware of any third party tender offer with respect to any such securities within the meaning of Rule 13e-1 under the Exchange Act.

(g)

Counterparty is not entering into this Confirmation to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for Shares) or to manipulate the price of the Shares (or any security convertible into or exchangeable for Shares) or in violation of the Exchange Act.

(h)

On and immediately after each of the Trade Date and the Premium Payment Date, (A) the total assets of Counterparty exceed the total 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 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).

(i)

Counterparty understands that notwithstanding any other relationship between Counterparty and Dealer and its affiliates, in connection with this Transaction and any other over-the-counter derivative transactions between Counterparty and Dealer or its affiliates, Dealer or its affiliate is acting as principal and is not a fiduciary or advisor in respect of any such transaction, including any entry, exercise, amendment, unwind or termination thereof.

II.

Representations, Warranties and Covenants of Counterparty and Dealer. Counterparty and Dealer hereby represent and warrant to Dealer and Counterparty, respectively, on the date hereof and on and as of the Premium Payment Date that:

(a)

Each is an “eligible contract participant” (as such term is defined in Section 1a(18) of the Commodity Exchange Act, as amended, other than a person that is an eligible contract participant under Section 1a(18)(C) of the Commodity Exchange Act).

(b)

Each of Dealer and Counterparty acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) thereof. Accordingly, Counterparty represents and warrants to Dealer that (i) it has the financial ability to bear the economic risk of its investment in the Transaction and is able to bear a total loss of its investment and its investments in and liabilities in respect of the Transaction, which it understands are not readily marketable, are not disproportionate to its net worth, and it is able to bear any loss in connection with the Transaction, including the loss of its entire investment in the Transaction, (ii) it is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act, (iii) it is entering into the Transaction for its own account and without a view to the distribution or resale thereof, (iv) the assignment, transfer or other disposition of the Transaction has not been and will not be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state securities laws, and (v) its financial condition is such that it has no need for liquidity with respect to its investment in the Transaction and no need to dispose of any portion thereof to satisfy any existing or contemplated undertaking or indebtedness and is capable of assessing the merits of and understanding (on its own behalf or through independent professional advice), and understands and accepts, the terms, conditions and risks of the Transaction.

9.	Other Provisions.

(a)

Opinions. On or prior to the Premium Payment Date, Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Trade Date, with respect to the due incorporation, existence and good standing of Counterparty in Delaware, the due authorization, execution and delivery of this Confirmation, and, in respect of the execution, delivery and performance of this Confirmation, the absence of any conflict with or breach of any material agreement governing indebtedness, Counterparty’s certificate of incorporation or Counterparty’s by-laws. Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement.

(b)

Repurchase/Adjustment 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/Adjustment Notice”) on such day if, following such repurchase, the Notice Percentage would be (i) greater than [__]¹⁶% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase/Adjustment Notice (or, in the case of the first such Repurchase/Adjustment Notice, greater by 0.5% than the Notice Percentage as of the date hereof); provided that Counterparty may provide Dealer with advance notice on or prior to any such day to the extent it reasonably expects that repurchases effected on such day may result in an obligation to deliver a Repurchase/Adjustment Notice (which advance notice shall be deemed a Repurchase/Adjustment Notice); provided, further that Counterparty shall not deliver any material non-public information to any employee of Dealer unless that employee has been identified to Counterparty as being on the “private side”. The parties agree that Counterparty’s obligation to provide any Repurchase/Adjustment Notice relating to a repurchase of Shares shall be satisfied by notice to Dealer of Counterparty’s related corporate authorization to repurchase such Shares or by notice of the implementation of a stock repurchase plan, forward contract, accelerated stock repurchase contract or similar transaction; provided that, Counterparty acknowledges and agrees that Dealer may, but is not required to, assume that the maximum number of Shares permitted to be repurchased pursuant to such authorization, plan, contract or transaction will be repurchased on the date on which such authorization, plan, contract or transaction becomes effective, subject to adjustments thereto as Dealer determines appropriate to account for the market price with respect to the Shares, Potential Adjustment Events and other corporate transactions with respect to Counterparty or the Shares and such other factors as Dealer determines relevant. The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the sum of (a) the product of the Number of Options and the Option Entitlement and (b) the number of Shares underlying any other similar call option transaction sold by Dealer to Counterparty and the denominator of which is the number of Shares outstanding on such day. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities, expenses and fees (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase/Adjustment Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase/Adjustment 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

¹⁶	To be 0.5% higher than the Notice Percentage as of the Trade Date, determined based on Dealer with the largest number of options.

proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or expects to be a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages, liabilities, expenses or fees referred to therein, then Counterparty, in lieu of indemnifying such Indemnified Person hereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages, liabilities, expenses or fees. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies that 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. [To the extent that Dealer is a party to other call option transactions with Counterparty with similar notice provisions, entry into this Confirmation shall be deemed a “Repurchase/Adjustment Notice” under such other call option transactions.]¹⁷

(c)

Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as such term is used in Regulation M under the Exchange Act, of any securities of 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 final day of the Trade Date, engage in any such distribution.

(d)

Transfer or Assignment.

(i)

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

(A)

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

(B)

Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the 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;

¹⁷	Include if dealer is a party to existing bond hedge transactions.

(D)

Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment except to the extent that the greater amount is due to a Change in Tax Law after the date of such transfer or assignment;

(E)

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

(F)

Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

(G)

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

(ii)

Dealer may, without Counterparty’s consent, transfer or assign (a “Transfer”) all or any part of its rights or obligations under the Transaction (A) to any affiliate of Dealer (1) that has a rating for its long term, unsecured and unsubordinated indebtedness that is equal to or better than Dealer’s credit rating at the time of such Transfer, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by Dealer or [Name of Dealer parent], or (B) to any other third party with a rating for its long term, unsecured and unsubordinated indebtedness equal to or better than the lesser of (1) the credit rating of Dealer at the time of the Transfer and (2) BBB+ by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”), or Baa 1 by Moody’s Investor Service, Inc. (“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 (x) the transferee in any such Transfer is a “dealer in securities” within the meaning of Section 475(c)(1) of the Code or the Transfer does not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code, (y) after any such Transfer, Counterparty will not (or Dealer will cause the transferee or assignee to agree that Counterparty will not), as a result of any withholding or deduction made by the transferee or assignee as a result of any Tax, receive from the transferee or assignee on any payment date or delivery date (after accounting for amounts paid by the transferee or assignee under Section 2(d)(i)(4) of the Agreement as well as such withholding or deduction) an amount or a number of Shares, as applicable, lower than the amount or the number of Shares, as applicable, that Dealer would have been required to pay or deliver to Counterparty in the absence of such Transfer (except to the extent such lower amount or number results from a Change in Tax Law after the date of such Transfer) and (z) Dealer shall cause the transferee or assignee to make such Payee Tax Representations and to provide such tax documentation as may reasonably be requested by Counterparty to permit Counterparty to make any necessary determinations pursuant to clause (y) of this proviso; and provided further that Dealer shall promptly provide written notice to Counterparty following any such Transfer. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (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 (after giving effect to such transfer or assignment and any resulting change in Dealer’s commercially reasonable Hedge

Positions) 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 (after giving effect to such transfer or assignment and any resulting change in Dealer’s commercially reasonable Hedge Positions) 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(l) 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, including, without limitation, under state or federal banking laws (“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 commercially reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its commercially 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 (“Dealer 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; provided that such Dealer Affiliates shall comply with the provisions of this Transaction in the same manner as Dealer would have been required to comply. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

(e)

Staggered Settlement. Notwithstanding anything to the contrary herein, if upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s hedging activities hereunder that would be customarily applicable to transactions of

this type by Dealer, Dealer may, by prior notice to Counterparty, satisfy its obligation to deliver any Shares or other securities on any date due (an “Original Delivery Date”) by making separate deliveries of Shares or such securities, as the case may be, at more than one time on or prior to such Original Delivery Date, so long as the aggregate number of Shares and other securities so delivered on or prior to such Original Delivery Date is equal to the number that, but for this provision, would have been deliverable on such Original Delivery Date.

Additional Termination Events.

(i)

Notwithstanding anything to the contrary in this Confirmation, if an event of default with respect to Counterparty occurs that results in the acceleration of the Convertible Notes pursuant to the terms of the Convertible Notes as set forth in Section 6.01 of the Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.

(ii)

Promptly (and in any event within five Scheduled Trading Days) following (i) any repurchase (which, for the avoidance of doubt, includes any exchange transaction) of Convertible Notes, including without limitation pursuant to Article 15 of the Indenture in connection with a “Fundamental Change” (as defined in the Indenture), (ii) any conversion of the Convertible Notes in exchange for delivery of any property or assets of Issuer or any of Issuer’s subsidiaries (howsoever described) (other than the delivery of conversion consideration pursuant to the terms of the Indenture), or (iii) any cancellation of Convertible Notes following any repurchase of Convertible Notes set forth in clause (i) for which no Repurchase Notice was previously delivered (any such event, a “Repurchase Event”), Counterparty, in the case of clause (i), may, and in the case of clauses (ii) and (iii), shall, notify Dealer in writing of such Repurchase Event and the number of Convertible Notes subject to such Repurchase Event (any such notice, a “Repurchase Notice”)[; provided that any “Repurchase Notice” delivered to Dealer pursuant to the Base Call Option Confirmation shall deemed to be a Repurchase Notice pursuant to this Confirmation and the terms of such Repurchase Notice shall apply, mutatis mutandis, to this Confirmation]¹⁹.

written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such 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 this Transaction corresponding to a number of Options (the “Repurchase Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repurchase Notice [minus the number of “Repurchase Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes]²⁰ 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.

(iii)

Notwithstanding anything to the contrary in the Equity Definitions, if, as a result of an Extraordinary Event, the Transaction would be cancelled or terminated (whether in whole or in part) pursuant to Article 12 of the Equity Definitions, an Additional Termination Event (with the Transaction (or portion thereof) being the Affected Transaction, Counterparty being the sole Affected Party and Dealer being the party entitled to designate an Early Termination Date pursuant to Section 6(h) of the Agreement) shall be deemed to occur, and, in lieu of Sections 12.7, 12.8 and 12.9 of the Equity Definitions, Section 6 of the Agreement shall apply to such Affected Transaction.

(ii)

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

(k)

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.

(l)

Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If in respect of the Transaction, an amount is payable by Dealer to Counterparty pursuant to Section 6(d)(ii) of the Agreement or Sections 12.7 or 12.8 of the Equity Definitions (any such amount, a “Payment Obligation”), Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic

²⁰	Insert for Additional Call Option Confirmation.

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, the Tender Offer Date, the Announcement Date (in the case of Nationalization, Insolvency or Delisting), the 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 8I(b) as of the date of such election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 6(d)(ii) of the Agreement 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 6(d)(ii) and 6(e) of the Agreement (the “Share Termination Payment Date”), 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 the purchase price paid in connection with the purchase of Share Termination Delivery Property, to the extent doing so results in a commercially reasonable Share Termination Unit Price.

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 will be applicable as if Physical Settlement applied to the Transaction and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable.

(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.

Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, based on the advice of counsel, the Shares acquired by Dealer for the purpose of effecting a commercially reasonable hedge of its obligations pursuant to the Transaction (other than any such Shares that were, at the time of acquisition by Dealer, “restricted securities” (as defined in Rule 144(a)(3) under the Securities Act)) (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, make available to Dealer an effective registration statement under the Securities Act to cover the resale of such Hedge Shares and (A) enter into a customary agreement, in form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary 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 of companies of comparable size, maturity and line of business, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered secondary 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 subject to entering into confidentiality agreements customary for transactions of this type; provided that if Counterparty elects clause (i) above but the items referred to therein are not completed in a timely manner, or if Dealer, in its 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 9(n) 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 comparable size, maturity and line of business, in form and substance commercially reasonably satisfactory to Dealer, including 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), and obligations to use commercially reasonable efforts to obtain opinions and certificates and such other documentation as is customary for private placement agreements for private placements of equity securities of companies comparable in size, maturity and line of business, all commercially 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 commercially reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement); or (iii) purchase the Hedge Shares from Dealer at the Relevant Price on such Exchange Business Days, and in the amounts, requested by Dealer. This Section 9(n) shall survive the termination, expiration or early unwind of the Transaction.

Right to Extend.

Status of Claims in Bankruptcy.
