(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 costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities 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 costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities as a result of such Potential Adjustment Event Change.

Representations and Warranties of Counterparty.

Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

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 to which Counterparty or any of its subsidiaries is a party

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.

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

Counterparty 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).

Each of it and its affiliates is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares.

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.

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.

The assets of Counterparty do not constitute “plan assets” under the Employee Retirement Income Security Act of 1974, as amended, the Department of Labor Regulations promulgated thereunder or similar law.

Other Provisions.

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) through (c) of this Confirmation. 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.

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 155.0 million (in the case of the first such notice) or (ii) thereafter more than 6.8 million less than the number of Shares included in the immediately preceding Repurchase Notice. 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 commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (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 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

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.

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.

Transfer or Assignment.

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:

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;

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);

Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, an undertaking

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;

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

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

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

Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction 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. 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(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

Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

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 such Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows:

in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date, but not prior to the beginning of the Settlement Averaging Period or, if applicable, any other date of valuation) or delivery times and how it will allocate the Shares it is required to deliver among the Staggered Settlement Dates or delivery times; and

the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date.

Communications with Employees of J.P. Morgan Securities LLC. If Counterparty interacts with any employee of J.P. Morgan Securities LLC with respect to the Transaction, Counterparty is hereby notified that such employee will act solely as an authorized representative of Dealer (and not as a representative of J.P. Morgan Securities LLC) in connection with the Transaction.

[Reserved.]

Additional Termination Events.

Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion or Make-Whole Conversion in respect of which a Notice of Conversion that is effective as to Counterparty has been delivered by the relevant converting Holder:

Counterparty shall, within one Scheduled Trading Day of the Conversion Date for such Early Conversion or Make-Whole Conversion, as the case may be, provide written notice (an “Early/Make-Whole Conversion Notice”) to Dealer specifying the number of Convertible Notes surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), and the giving of such Early/Make-Whole Conversion Notice shall constitute an Additional Termination Event as provided in this clause (i);

upon receipt of any such Early/Make-Whole Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be no earlier than one Scheduled Trading Day following the Conversion Date for such Early Conversion or Make-Whole Conversion, as applicable) with respect to the portion of the Transaction corresponding to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) the number of Affected Convertible Notes minus the “Affected Number of Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Affected Convertible Notes and (y) the Number of Options as of the Conversion Date for such Early Conversion or Make-Whole Conversion, as applicable;

any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided that the amount payable with respect to such termination shall not be greater than the Applicable Percentage multiplied by (x) the sum of (i) the amount of cash paid (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the number of Shares delivered (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note, multiplied by the fair market value of one Share as determined by the Calculation Agent, minus (y) USD 1,000;

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 or Make-Whole Conversion, as the case may be, 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

the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such Early Conversion or Make-Whole Conversion, as applicable, the Number of Options shall be reduced by the Affected Number of Options.

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

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.

Amendments to Equity Definitions.

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.

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

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.

Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging 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 satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering; 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, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its 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 then-current market price on such Exchange Business Days, and in the amounts and at such time(s), reasonably requested by Dealer.

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.

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 its discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity

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.

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.

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

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 the weighted average of the types and amounts of consideration received by holders of Shares upon consummation of such Merger Event (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

(A) Counterparty shall give Dealer commercially reasonable advance (but in any event at least one Exchange Business Day prior to the relevant Adjustment Notice Deadline) 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 (other than a Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in Section 14.04(b) or Section 14.04(d) of the Indenture) or Merger Event and (B) promptly following any such adjustment, or any adjustment in respect of the Dilution Adjustment Provision set forth in Section 14.04(b) or Section 14.04(d) of the Indenture, Counterparty shall give Dealer written notice of the details of such adjustment. The “Adjustment Notice Deadline” means (i) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in Section 14.04(a) of the Indenture, the relevant Ex-Dividend Date (as such term is defined in the Indenture) or Effective Date (as such term is defined in the Indenture), as the case may be, (ii) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision in the first formula set forth in Section 14.04(c) of the Indenture, the first Trading Day (as such term is defined in the Indenture) of the period referred to in the definition of “SP0” in such formula, (iii) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision in the second formula set forth in Section 14.04(c) of the Indenture, the first Trading Day (as such term is defined in the Indenture) of the Valuation Period (as such term is defined in the Indenture), (iv) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in

In the event the sale of the “Option Securities” (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) of this Confirmation, 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; provided that Counterparty shall purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates in connection with the Transaction at the then prevailing market price. Each of Dealer and Counterparty represents and acknowledges to the other that, subject to the proviso included in this Section 9(v), upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

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.

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(j)(i)), and upon the occurrence of a Merger Date, the occurrence of a Tender Offer Date, or declaration by Counterparty of the terms

Determinations. Dealer (including, without limitation, in its capacity as Calculation Agent) shall deliver to Counterparty, within five Exchange Business Days after a written request by Counterparty, a written explanation describing in reasonable detail any calculation, adjustment or determination made by it (including the methodology, interest rates, quotations, market data (including volatility) and information from internal sources used in making such calculation, adjustment or determination, but without disclosing Dealer’s proprietary or confidential models or other information that is proprietary, confidential or otherwise subject to contractual, legal or regulatory obligations to not disclose such information).

Tax Forms. For the purposes of Sections 4(a)(i) and (ii) of the Agreement, Counterparty agrees to deliver to Dealer one duly executed and completed United States Internal Revenue Service Form W-9 (or successor thereto). Such forms or documents shall be delivered upon (i) execution of this Confirmation and (ii) reasonable request of Dealer. Counterparty agrees that if any form previously delivered has expired or become obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Dealer in writing of its inability to do so.

For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

HIRE Act. “Indemnifiable Tax”, as defined in Section 14 of the Agreement, shall not include any tax imposed on payments treated as dividends from sources within the United States under Section 871(m) of the Code or any regulations issued thereunder.

(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 costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities 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 costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities as a result of such Potential Adjustment Event Change.

Representations and Warranties of Counterparty.

Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

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 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.

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.

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

Counterparty 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).

Each of it and its affiliates is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares.

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.

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.

The assets of Counterparty do not constitute “plan assets” under the Employee Retirement Income Security Act of 1974, as amended, the Department of Labor Regulations promulgated thereunder or similar law.

Counterparty is not a “financial end user” as defined in 12 CFR §45.2.

Other Provisions.

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) through (c) of this Confirmation. 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.

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 155.0 million (in the case of the first such notice) or (ii) thereafter more than 6.8 million less than the number of Shares included in the immediately preceding Repurchase Notice. 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 commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (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 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 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 for any settlement of any proceeding contemplated by this paragraph that is effected without its written

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.

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.

Transfer or Assignment.

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:

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;

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);

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;

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;

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

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

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

Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction 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. 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(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 (“Applicable Restrictions”), owns,

Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

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 such Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows:

in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date, but not prior to the beginning of the Settlement Averaging Period or, if applicable, any other date of valuation) or delivery times and how it will allocate the Shares it is required to deliver among the Staggered Settlement Dates or delivery times; and

the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date.

[Reserved.]

[Reserved.]

Additional Termination Events.

Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion or Make-Whole Conversion in respect of which a Notice of Conversion that is effective as to Counterparty has been delivered by the relevant converting Holder:

Counterparty shall, within one Scheduled Trading Day of the Conversion Date for such Early Conversion or Make-Whole Conversion, as the case may be, provide written notice (an “Early/Make-Whole Conversion Notice”) to Dealer specifying the number of Convertible Notes surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), and the giving of such Early/Make-Whole Conversion Notice shall constitute an Additional Termination Event as provided in this clause (i);

upon receipt of any such Early/Make-Whole Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which

any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided that the amount payable with respect to such termination shall not be greater than the Applicable Percentage multiplied by (x) the sum of (i) the amount of cash paid (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the number of Shares delivered (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note, multiplied by the fair market value of one Share as determined by the Calculation Agent, minus (y) USD 1,000;

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 or Make-Whole Conversion, as the case may be, 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

the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such Early Conversion or Make-Whole Conversion, as applicable, the Number of Options shall be reduced by the Affected Number of Options.

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 that results in the acceleration of Counterparty’s payment obligations under the Convertible Notes pursuant to the terms of the Indenture, then such acceleration 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.

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

Amendments to Equity Definitions.

Section 11.2(e)(vii) of the Equity Definitions is hereby amended by deleting the words “a diluting or concentrative” and replacing them with the words “a material” and adding the phrase “or the Options” at the end of the sentence.

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.

Section 12.9(b)(vi) of the Equity Definitions is hereby amended by (1) adding the word “or” immediately before subsection “(B)”, (2) deleting the comma at the end of subsection (A), (3) deleting subsection (C) in its entirety, (4) deleting the word “or” immediately preceding subsection (C) and (5) replacing the words “either party” in the last sentence of such Section with “the Hedging Party”.

Setoff. Each party waives any and all rights it may have to setoff, whether arising under any agreement, applicable law or otherwise.

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 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(f) as of the date of such election and (c) Dealer agrees 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) of the Agreement, as the case may be, shall apply.

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.

Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging 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 satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering; 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, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its 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 then-current market price on such Exchange Business Days, and in the amounts and at such time(s), reasonably requested by Dealer.

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.

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 its discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases or sales of Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer; provided that no such Valid Day or other date of valuation, payment or delivery may be postponed or added more than 50 Valid Days after the final day in the original Settlement Averaging Period or original other date of valuation, payment or delivery, as the case may be.

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.

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.

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

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 the weighted average of the types and amounts of consideration received by holders of Shares upon consummation of such Merger Event (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

(A) Counterparty shall give Dealer commercially reasonable advance (but in any event at least one Exchange Business Day prior to the relevant Adjustment Notice Deadline) 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 (other than a Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in Section 14.04(b) or Section 14.04(d) of the Indenture) or Merger Event and (B) promptly following any such adjustment, or any adjustment in respect of the Dilution Adjustment Provision set forth in Section 14.04(b) or Section 14.04(d) of the Indenture, Counterparty shall give Dealer written notice of the details of such adjustment. The “Adjustment Notice Deadline” means (i) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in Section 14.04(a) of the Indenture, the relevant Ex-Dividend Date (as such term is defined in the Indenture) or Effective Date (as such term is defined in the Indenture), as the case may be, (ii) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision in the first formula set forth in Section 14.04(c) of the Indenture, the first Trading Day (as such term is defined in the Indenture) of the period referred to in the definition of “SP0” in such formula, (iii) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision in the second formula set forth in Section 14.04(c) of the Indenture, the first Trading Day (as such term is defined in the Indenture) of the Valuation Period (as such term is defined in the Indenture), (iv) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in Section 14.04(e) of the Indenture, the first Trading Day (as such term is defined in the Indenture) of the period referred to in the definition of “SP’” in the formula in such Section, and (v) for any Merger Event, the effective date of such Merger Event (or, if earlier, the first day of any valuation or similar period in respect of such Merger Event).

Wall Street Transparency and Accountability Act. In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), the parties hereby agree that neither the enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)).

Agreements and Acknowledgements Regarding Hedging. 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.

Early Unwind. In the event the sale of the “Option Securities” (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) of this Confirmation, 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; provided that Counterparty shall purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates in connection with the Transaction at the then prevailing market price. Each of Dealer and Counterparty represents and acknowledges to the other that, subject to the proviso included in this Section 9(v), upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

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.

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(j)(i)), 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 adjust the Cap Price to maintain the fair value of the Options to Dealer; provided that in no event shall the Cap Price be less than the Strike Price. For the avoidance of doubt, any adjustment pursuant to this Section 9(x) shall not be duplicative of any other adjustment made pursuant to this Confirmation, including without limitation pursuant to “Consequences of Announcement Events” in Section 3 of this Confirmation.

Determinations. Dealer (including, without limitation, in its capacity as Calculation Agent) shall deliver to Counterparty, within five Exchange Business Days after a written request by Counterparty, a written explanation describing in reasonable detail any calculation, adjustment or determination made by it (including the methodology, interest rates, quotations, market data (including volatility) and information from internal sources used in making such calculation, adjustment or determination, but without disclosing Dealer’s proprietary or confidential models or other information that is proprietary, confidential or otherwise subject to contractual, legal or regulatory obligations to not disclose such information).

Tax Forms. For the purposes of Sections 4(a)(i) and (ii) of the Agreement, Counterparty agrees to deliver to Dealer one duly executed and completed United States Internal Revenue Service Form W-9 (or successor thereto). Such forms or documents shall be delivered upon (i) execution of this Confirmation and (ii) reasonable request of Dealer. Counterparty agrees that if any form previously delivered has expired or become obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Dealer in writing of its inability to do so.

Withholding Tax Imposed on Payments to non-US Counterparties under the United States Foreign Account Tax Compliance Act. “Indemnifiable Tax”, as defined in Section 14 of the Agreement, shall not include any U.S. federal withholding tax imposed or collected pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (a “FATCA Withholding Tax”). For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

HIRE Act. “Indemnifiable Tax”, as defined in Section 14 of the Agreement, shall not include any tax imposed on payments treated as dividends from sources within the United States under Section 871(m) of the Code or any regulations issued thereunder. For the avoidance of doubt, any such tax imposed under Section 871(m) of the Code is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

Payee Tax Representations. For the purposes of Section 3(f) of the Agreement:

Counterparty makes the following representations:

It is a “U.S. person” (as that term is used in section 1.1441-4(a)(3)(ii) of United States Treasury Regulations for U.S. federal income tax purposes.

Method of Adjustment:

(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 the adjustment to be made to any one or more of the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction in a commercially reasonable manner; 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 an adjustment, as determined by it, 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 have the right to adjust any variable relevant to the exercise, settlement or payment for the Transaction as appropriate to reflect the costs (including, but not limited to,

hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities 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 costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities as a result of such Potential Adjustment Event Change.

Representations and Warranties of Counterparty.

Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

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 to which Counterparty or any of its subsidiaries is a party

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.

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

Counterparty 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).

Each of it and its affiliates is not, on the date hereof, in possession of any material non-public information with respect to Counterparty or the Shares.

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.

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.

The assets of Counterparty do not constitute “plan assets” under the Employee Retirement Income Security Act of 1974, as amended, the Department of Labor Regulations promulgated thereunder or similar law.

Other Provisions.

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) through (c) of this Confirmation. 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.

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 155.0 million (in the case of the first such notice) or (ii) thereafter more than 6.8 million less than the number of Shares included in the immediately preceding Repurchase Notice. 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 commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (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 Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written

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.

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.

Transfer or Assignment.

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:

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;

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);

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;

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;

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

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

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

Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction 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. 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(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

Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

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 such Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows:

in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date, but not prior to the beginning of the Settlement Averaging Period or, if applicable, any other date of valuation) or delivery times and how it will allocate the Shares it is required to deliver among the Staggered Settlement Dates or delivery times; and

the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date.

[Reserved].

Additional Termination Events.

Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion or Make-Whole Conversion in respect of which a Notice of Conversion that is effective as to Counterparty has been delivered by the relevant converting Holder:

Counterparty shall, within one Scheduled Trading Day of the Conversion Date for such Early Conversion or Make-Whole Conversion, as the case may be, provide written notice (an “Early/Make-Whole Conversion Notice”) to Dealer specifying the number of Convertible Notes surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected Convertible Notes”), and the giving of such Early/Make-Whole Conversion Notice shall constitute an Additional Termination Event as provided in this clause (i);

upon receipt of any such Early/Make-Whole Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be no earlier than one Scheduled Trading Day following the Conversion Date for such Early Conversion or Make-Whole Conversion, as applicable) with respect to the portion of the Transaction corresponding to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) the number of Affected Convertible Notes minus the “Affected Number of Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Affected Convertible Notes and (y) the Number of Options as of the Conversion Date for such Early Conversion or Make-Whole Conversion, as applicable;

any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided that the amount payable with respect to such termination shall not be greater than the Applicable Percentage multiplied by (x) the sum of (i) the amount of cash paid (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the number of Shares delivered (if any) to the Holder (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note, multiplied by the fair market value of one Share as determined by the Calculation Agent, minus (y) USD 1,000;

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 or Make-Whole Conversion, as the case may be, 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

the Transaction shall remain in full force and effect, except that, as of the Conversion Date for such Early Conversion or Make-Whole Conversion, as applicable, the Number of Options shall be reduced by the Affected Number of Options.

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 that results in the acceleration of Counterparty’s payment obligations under the Convertible Notes pursuant to the terms of the Indenture, then such acceleration 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.

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.

Amendments to Equity Definitions.

Section 11.2(e)(vii) of the Equity Definitions is hereby amended by deleting the words “a diluting or concentrative” and replacing them with the words “a material” and adding the phrase “or the Options” at the end of the sentence.

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”.

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.

Section 12.9(b)(vi) of the Equity Definitions is hereby amended by (1) adding the word “or” immediately before subsection “(B)”, (2) deleting the comma at the end of subsection (A), (3) deleting subsection (C) in its entirety, (4) deleting the word “or” immediately preceding subsection (C) and (5) replacing the words “either party” in the last sentence of such Section with “the Hedging Party”.

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)

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.

Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging 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 satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering; 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, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its 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 then-current market price on such Exchange Business Days, and in the amounts and at such time(s), reasonably requested by Dealer.

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.

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 its discretion, that such action is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable Dealer to effect purchases or sales of Shares in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer; provided that no such Valid Day or other date of valuation, payment or delivery may be postponed or added more than 50 Valid Days after the final day in the original Settlement Averaging Period or original other date of valuation, payment or delivery, as the case may be.

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.

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.

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

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 the weighted average of the types and amounts of consideration received by holders of Shares upon consummation of such Merger Event (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

(A) Counterparty shall give Dealer commercially reasonable advance (but in any event at least one Exchange Business Day prior to the relevant Adjustment Notice Deadline) 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 (other than a Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in Section 14.04(b) or Section 14.04(d) of the Indenture) or Merger Event and (B) promptly following any such adjustment, or any adjustment in respect of the Dilution Adjustment Provision set forth in Section 14.04(b) or Section 14.04(d) of the Indenture, Counterparty shall give Dealer written notice of the details of such adjustment. The “Adjustment Notice Deadline” means (i) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision set forth in Section 14.04(a) of the Indenture, the relevant Ex-Dividend Date (as such term is defined in the Indenture) or Effective Date (as such term is defined in the Indenture), as the case may be, (ii) for any Potential Adjustment Event in respect of the Dilution Adjustment Provision in the first formula set forth in Section 14.04(c) of the

Wall Street Transparency and Accountability Act. In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), the parties hereby agree that neither the enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as defined in the Agreement)).

Agreements and Acknowledgements Regarding Hedging. 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.

Early Unwind. In the event the sale of the “Option Securities” (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) of this Confirmation, 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; provided that Counterparty shall purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its affiliates in connection with the Transaction at the then prevailing market price. Each of Dealer and Counterparty represents and acknowledges to the other that, subject to the proviso included in this Section 9(v), upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

Payment by Counterparty.

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(j)(i)), 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 adjust the Cap Price to maintain the fair value of the Options to Dealer; provided that in no event shall the Cap Price be less than the Strike Price. For the avoidance of doubt, any adjustment pursuant to this Section 9(x) shall not be duplicative of any other adjustment made pursuant to this Confirmation, including without limitation pursuant to “Consequences of Announcement Events” in Section 3 of this Confirmation.

Determinations. Dealer (including, without limitation, in its capacity as Calculation Agent) shall deliver to Counterparty, within five Exchange Business Days after a written request by Counterparty, a written explanation describing in reasonable detail any calculation, adjustment or determination made by it (including the methodology, interest rates, quotations, market data (including volatility) and information from internal sources used in making such calculation, adjustment or determination, but without disclosing Dealer’s proprietary or confidential models or other information that is proprietary, confidential or otherwise subject to contractual, legal or regulatory obligations to not disclose such information).
