The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation.  In the event of any inconsistency between the Equity Definitions and this Confirmation, this Confirmation shall govern.  Certain defined terms used herein are based on terms that are defined in the Offering Memorandum dated June 9, 2015 (the “Offering Memorandum”) relating to the 2.25% Convertible Senior Notes due 2022 (as originally issued by Counterparty, the “Convertible Notes” and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty in an aggregate initial principal amount of USD 300,000,000 (as increased by an aggregate principal amount of USD 35,699,000 pursuant to the exercise by the Initial Purchasers (as defined herein) of their option to purchase additional Convertible Notes pursuant to the Purchase Agreement (as defined herein)) pursuant to an Indenture dated June 15, 2015 between Counterparty and U.S. Bank National Association, as trustee (the “Indenture”).  In the event of any inconsistency between the terms defined in the Offering Memorandum, the Indenture and this Confirmation, this Confirmation shall govern.  The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Offering Memorandum.  If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes of this Confirmation.  The parties further acknowledge that the Indenture section numbers used herein are based on the Indenture as executed.  Subject to the foregoing, references to the Indenture herein are references to the Indenture as in effect on the date of its execution and if the Indenture is amended or supplemented following such date (other than any amendment or supplement (x) pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 4.07(a) of the Indenture, subject, in the case of this clause (y), to the second paragraph under “Method of Adjustment” in Section 3), any such amendment or supplement will be disregarded for purposes of this Confirmation unless the parties agree otherwise in writing.

Adjustments applicable   to the Transaction:
    	
 
    	
 
    
	
 
    	
 
    	
 
    
	
Potential Adjustment   Events:
    	
 
    	
Notwithstanding Section 11.2(e) of the   Equity Definitions, a “Potential Adjustment Event” means an occurrence of any   event or condition, as set forth in any Dilution Adjustment Provision, that   would result in an adjustment under the Indenture to the “Conversion Rate” or   the composition of a “unit of Reference Property” or to any “Last Reported   Sale Price” , “Daily VWAP,” “Daily Conversion Value” or “Daily   Settlement Amount” (each as defined in the Indenture). For the avoidance of   doubt, Dealer shall not have any delivery or payment obligation hereunder in   respect of any “Distributed Property” delivered by Counterparty pursuant to   the fourth sentence of Section 4.05(c) of the Indenture or any   payment obligation in respect of any cash paid by Counterparty pursuant to   the fourth sentence of Section 4.05(d) of the Indenture (collectively,   the “Conversion Rate Adjustment Fallback Provisions”),   and no adjustment shall be made to the terms of the Transaction, on account   of (x) any event or condition described in the Conversion Rate   Adjustment Fallback Provisions or (y) any other transaction in which   holders of the Convertible Notes are entitled to participate, in each case,   in lieu of an adjustment under the Indenture of the type referred to in the   immediately preceding sentence (including, without limitation, pursuant to   the Conversion Rate Adjustment Fallback Provisions).
    
	
 
    	
 
    	
 
    
	
Method of Adjustment:
    	
 
    	
Calculation Agent Adjustment, which means that,   notwithstanding Section 11.2(c) of the Equity Definitions, upon any   Potential Adjustment Event, the Calculation Agent shall make an adjustment   corresponding to the adjustment to be made pursuant to the Indenture to any   one or more of the Strike Price, Number of Options and/or Option Entitlement.
    
	
 
    	
 
    	
 
    
	
 
    	
 
    	
Notwithstanding the foregoing and “Consequences of   Merger Events / Tender Offers” below, 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 4.06 of the Indenture, Section   4.07(a) 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 and/or Option Entitlement in a commercially reasonable manner, after   consultation with Counterparty; 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 in a   commercially reasonable manner after consultation with Counterparty, to the   terms hereof in order to account for such Potential Adjustment Event. 
    
	
 
    	
 
    	
 
    
	
 
    	
 
    	
For the avoidance of doubt, whenever the Calculation   Agent, the Hedging Party, the Determining Party, or Dealer is called upon to   make an adjustment pursuant to the terms of this Transaction to take into   account the effect of an event, the Calculation Agent, the Hedging Party, the   Determining Party of Dealer, as applicable, shall make such adjustment by   reference to the effect of such event on the Hedging Party, assuming that the   Hedging Party maintains a commercially reasonable hedge position.
    
	
 
    	
 
    	
 
    
	
Dilution Adjustment   Provisions:

Applicable; provided that   notwithstanding Section 12.1(d) of the Equity Definitions, a   “Tender Offer” means the occurrence of any event or condition set forth in   Section 4.05(e) of the Indenture.
    
	
 
    	
 
    	
 
    
	
Consequences of Merger   Events / Tender Offers:
    	
 
    	
Notwithstanding Section 12.2 and   Section 12.3 of the Equity Definitions, upon the occurrence of a Merger   Event or a Tender Offer that is required under the terms of the Indenture to   result in an adjustment to the terms of the Convertible Notes, the Calculation   Agent shall make an adjustment corresponding to the adjustment to be made   pursuant to the Indenture to any one or more of the nature of the Shares (in   the case of a Merger Event), Strike Price, Number of Options, Option   Entitlement, the definitions of “Exchange”, “Relevant Price”, “Settlement   Averaging Period”, “Valid Day”, “Scheduled Valid Day”, “Market Disruption   Event”, and/or the number of Share thresholds in   Section 9(b)(i) and 9(b)(ii) of this Confirmation, subject to   the second paragraph under “Method of Adjustment”; provided, however, that such adjustment shall be made without   regard to any adjustment to the Conversion Rate pursuant to any Excluded   Provision; provided further that if, with   respect to a Merger Event or a Tender Offer, (i) the consideration for   the Shares includes (or, at the option of a holder of Shares, may include)   shares of an entity or person that is not a corporation or is not organized   under the laws of the United States, any State thereof or the District of   Columbia or (ii) the Counterparty to the Transaction following such   Merger Event or Tender Offer will not be

Cancellation and Payment (Calculation Agent   Determination); provided that, in addition to   the provisions of Section 12.6(a)(iii) of the Equity Definitions,   it will also constitute a Delisting if the Exchange is located in the United   States and the Shares are not immediately re-listed, re-traded or re-quoted   on any of the New York Stock Exchange, The NASDAQ Global Select Market or The   NASDAQ Global Market (or their respective successors); if the Shares are   immediately re-listed, re-traded or re-quoted on any of the New York Stock   Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or   their respective successors), such exchange or quotation system shall   thereafter be deemed to be the Exchange.

“, provided that any such inability that occurs   solely due to the deterioration of the creditworthiness of the Hedging Party   shall not be deemed a Hedging Disruption. For the avoidance of doubt, the   term “equity price risk” shall be deemed to include, but shall not be limited   to, stock price and volatility risk.

8.                                      Representations and Warranties of Counterparty.

 

Each of the representations and warranties of Counterparty set forth in Section 3 of the Purchase Agreement (the “Purchase Agreement”), dated as of June 9, 2015, between Counterparty and J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC, as representatives of the Initial Purchasers party thereto (the “Initial Purchasers”), are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein, except to the extent that such representations and warranties, if not true or correct, would not have a material adverse effect on the power or ability of Counterparty to execute and deliver this Confirmation or to perform its obligations hereunder.  Counterparty hereby further represents and warrants to Dealer on the date hereof and on and as of the Premium Payment Date that:

 

(a)                                 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.

 

(b)                                 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.

 

(c)                                  No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act of 1933, as amended (the “Securities Act”) or state securities laws.

 

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

 

(e)                                  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).

 

(f)                                   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.

 

(g)                                  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.

 

(h)                                 Counterparty (A) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its

associated persons, unless it has otherwise notified the broker-dealer in writing; and (C) has total assets of at least $50 million.

 

9.                                      Other Provisions.

 

(a)                                 [Reserved]

 

(b)                                 Repurchase Notices.  Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than 119,865,515 (in the case of the first such notice) or (ii) thereafter more than 5,489,841 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 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 reasonable 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 commercially reasonable fees and expenses of such counsel related to such proceeding.  Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment.  Counterparty shall not, without the prior written consent of the Indemnified Person (such consent not to be unreasonably withheld, conditioned or delayed), effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person.  If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities.  The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.  The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

 

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

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

 

(e)                                  Transfer or Assignment.

 

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

 

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

 

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

 

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

 

(D)                               Dealer will not, as a result of such transfer 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;

 

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

 

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

 

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

 

(ii)                                  Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction (A) to any affiliate of Dealer (1) that has a rating for its long term, unsecured and unsubordinated indebtedness that is equal to or better than Dealer’s credit rating at the time of such transfer or 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 Guarantor, or (B) to any other third party with a rating for its long term, unsecured and unsubordinated indebtedness equal to or better than the lesser of (1) the credit rating of Dealer at the time of the transfer and (2) A- by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”), or A3 by Moody’s Investor Service, Inc. (“Moody’s”) or, if either S&P or 

 

16











 

Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer.  If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its good faith and 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(m) 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 each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding.  The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding.  The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in good faith and in its reasonable discretion.  The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in good faith and in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

 

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

 

(f)                                   Staggered Settlement.  If upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s hedging activities hereunder, Dealer reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares 

 

17











 

to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) as follows:

 

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

 

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

 

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

 

(g)                                  Matters Relating to Dealer and Agent

 

(i)                                     Credit Suisse Securities (USA) LLC (“CSS”), in its capacity as Agent solely for Dealer (and not as Agent for Counterparty) will be responsible for (A) effecting the Transaction, (B) issuing all required confirmations and statements to Dealer and Counterparty, (C) maintaining books and records relating to the Transaction in accordance with its standard practices and procedures and in accordance with applicable law and (D) unless otherwise requested by Counterparty, receiving, delivering, and safeguarding Counterparty’s funds and any securities in connection with the Transaction, in accordance with its standard practices and procedures and in accordance with applicable law.

 

(ii)                                  Agent is acting in connection with the Transaction solely in its capacity as Agent for Dealer (and not as Agent for Counterparty) pursuant to instructions from Dealer.  Agent shall have no responsibility or personal liability to Dealer or Counterparty arising from any failure by Dealer or Counterparty to pay or perform any obligations hereunder, or to monitor or enforce compliance by Dealer or Counterparty with any obligation hereunder, including, without limitation, any obligations to maintain collateral.  Each of Dealer and Counterparty agrees to proceed solely against the other to collect or recover any securities or monies owing to it in connection with or as a result of the Transaction.  Agent shall otherwise have no liability in respect of the Transaction, except for its gross negligence or willful misconduct in performing its duties as Agent. For the avoidance of doubt, any performance by Dealer of its obligations hereunder solely to CSS shall not relieve Dealer of such obligations. Any performance by Counterparty of its obligations (including notice obligations) through or by means of CSS’ agency for Dealer shall constitute good performance of Counterparty’s obligations hereunder to Dealer.

 

(iii)                               Dealer is an “OTC derivatives dealer” as such term is defined in the Exchange Act and is an affiliate of Agent.

 

(iv)                              Dealer is not a member of the Securities Investor Protection Corporation.

 

(v)                                 Any and all notices, demands, or communications of any kind relating to the Transaction between Dealer and Counterparty shall be transmitted exclusively through Agent at the following address:

(h)                                 Additional Termination Events.

 

(i)                                     Notwithstanding anything to the contrary in this Confirmation if an event of default occurs under the terms of the Convertible Notes as set forth in Section 7.01 of the Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.

 

(ii)                                  Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty, within the applicable time period set forth under “Notice of Exercise” of any Notice of Exercise in respect of Options that relate to Convertible Notes as to which additional Shares would be added to the Conversion Rate pursuant to Section 4.04 of the Indenture in connection with a “Make-Whole Fundamental Change” (as defined in the Indenture) (such Convertible Notes, “Make-Whole Convertible Notes”) shall constitute an Additional Termination Event as provided in this Section 1.  Upon receipt of any such Notice of Exercise, Dealer shall designate an Exchange Business Day following such Additional Termination Event (which Exchange Business Day shall in no event be earlier than the related settlement date for such Convertible Notes) as an Early Termination Date with respect to the portion of this Transaction corresponding to a number of Options (the “Make-Whole Conversion Options”) equal to the lesser of (A) the number of such Options specified in such Notice of Exercise minus the number of “Make-Whole Conversion Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes and (B) the Number of Options as of the date Dealer designates such Early Termination Date (prior to giving effect to a reduction thereto on such date pursuant to the immediately following sentence).  As of any such Early Termination Date, the Number of Options shall be reduced by the applicable number of Make-Whole Conversion Options.  Any payment hereunder with respect to such termination of the Make-Whole Conversion Options shall be calculated pursuant to Section 6 of the Agreement (but using a volatility input that is equal to the Relevant Volatility Input) as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the number of Make-Whole Conversion Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction (and, for the avoidance of doubt, in determining the amount payable pursuant to Section 6 of the Agreement, the Calculation Agent shall not take into account any adjustments to the Option Entitlement that result from corresponding adjustments to the Conversion Rate pursuant to Section 4.04 of the Indenture); provided that the amount of cash deliverable in respect of such early termination by Dealer to Counterparty shall not be greater than the product of (x) the Applicable Percentage, (y) the number of Make-Whole Conversion Options and (z) the excess of (I) (1) the Conversion Rate (after taking into account any applicable adjustments to the Conversion Rate pursuant to Section 4.04 of the Indenture) multiplied by (2) a price per Share determined by the Calculation Agent over (II) the principal amount per Make-Whole Convertible Note, as determined by the Calculation Agent. “Relevant Volatility Input” means a volatility input that is determined by Dealer in good faith and in a commercially reasonable manner and which, without limitation, may 

 

19











 

be based on implied volatility levels for options on the Shares with strike prices approximate to the Strike Price of the Transaction or approximate to the strike price of over-the-counter equity options on the Shares that are included in its commercially reasonable Hedge Positions with respect to the Transaction, in each case, as determined by Dealer in good faith and a commercially reasonable manner; provided that, if (i) Dealer (whether in its capacity as “Calculation Agent”, “Determining Party”, “Hedging Party” or otherwise) is required to determine a volatility input under any over-the-counter equity option transaction to which Dealer is a party and to which Counterparty (or, if different, Issuer) is party relating to the Shares (such equity option transactions, “Relevant Positions”) and (ii) Dealer determines that such Relevant Positions (or a portion thereof) are terminated, cancelled, offset or otherwise unwound at approximately the same time (as determined by Dealer in good faith and commercially reasonably) as the Transaction (or portion thereof) is terminated, cancelled, offset or otherwise unwound, Dealer shall use a Relevant Volatility Input that is no less than such volatility input for such Relevant Positions. For the avoidance of doubt, a Relevant Volatility Input that is equal to the volatility input for any Relevant Positions shall, in no event, be deemed to be commercially unreasonable.

 

(iii)                               In addition, notwithstanding anything to the contrary in this Confirmation:

 

(A)                               Promptly following any Repayment Event (as defined below) (but, in any event, within 5 Scheduled Valid Days following settlement thereof), Counterparty may notify Dealer of such Repayment Event and the aggregate principal amount of Convertible Notes subject to such Repayment Event (the “Repayment Convertible Notes”) (any such notice, a “Repayment Notice”); provided that any “Repayment Notice” delivered to Dealer pursuant to the Base Call Option Confirmation shall be deemed to be a Repayment Notice pursuant to this Confirmation and the terms of such Repayment Notice shall apply, mutatis mutandis, to this Confirmation. The receipt by Dealer from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section 9(h).

 

(B)                               Upon receipt of any such Repayment Notice, Dealer shall designate an Exchange Business Day following receipt of such Repayment Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related settlement date for the relevant Repayment Event) as an Early Termination Date with respect to a portion (the “Repayment Terminated Portion”) of the Transaction consisting of a number of Options (the “Repayment Options”) equal to the lesser of (A) the number of Repayment Convertible Notes in denominations of USD1,000 that are subject to the relevant Repayment Event (and for the purposes of determining whether any Convertible Notes will be Repayment Convertible Notes hereunder or under, and as defined in, the Base Call Option Confirmation, Convertible Notes that are subject to a Repayment Event shall be allocated first to the Base Call Option Confirmation until all Options thereunder are exercised or terminated and (B) the Number of Options as of the date Dealer designates such Early Termination Date (prior to giving effect to a reduction thereto on such date pursuant to the immediately following sentence).  As of any such Early Termination Date, the Number of Options shall be reduced by the applicable number of Repayment Options.

 

(C)                               Any payment or delivery in respect of such termination of the Repayment Terminated Portion of the Transaction shall be made pursuant to Section 6 of the Agreement as if an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Repayment Options.  Counterparty shall be the sole Affected Party with respect to such Additional Termination Event and the Repayment Terminated Portion of the Transaction shall be the sole Affected Transaction. “Repayment Event” means that (i) any Convertible Notes are

 

20












 

repurchased by Counterparty or any of its subsidiaries, (ii) any Convertible Notes are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the Convertible Notes (other than upon an event of default under the Convertible Notes described in the first paragraph of this Section 9(h)), or (iv) any Convertible Notes are exchanged by or for the benefit of the Holders (as defined in the Indenture) thereof for any other securities of Counterparty or any of its Affiliates (as defined in the Indenture) (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction; provided that (x) no conversion of Convertible Notes pursuant to the terms of the Indenture shall constitute a Repayment Event and (y) no surrender of a Convertible Note for repurchase in respect of which Counterparty has elected to designate a financial institution for exchange in lieu of repurchase pursuant to Section 4.11 of the Indenture shall constitute a Repayment Event.  Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act and the rules and regulations thereunder, in respect of any action taken by Counterparty or any of its Affiliates (as defined in the Indenture) in respect of a Repayment Event, including, without limitation, the delivery of a Repayment Notice.

 

(D)                               Counterparty shall cause any Convertible Notes subject to a Repayment Event to be promptly cancelled or no longer outstanding and acknowledges and agrees that, except to the extent provided above in this Section 9(h), all such Convertible Notes subject to a Repayment Event will be deemed for all purposes under the Transaction to be permanently extinguished or no longer outstanding.

 

(i)                                     Amendments to the Equity Definitions.

 

(i)                                    Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) at Dealer’s option, 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.”

 

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

 

(j)                                    Setoff.  Obligations under the Transaction shall not be set off by either party against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise.  For the avoidance of doubt, in the event of bankruptcy or liquidation of either Counterparty or Dealer neither party shall have the right to set off any obligation that it may have to the other party under the Transaction against any obligation such other party may have to it, whether arising under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of law or otherwise.

 

(k)                                 Alternative Calculations and Payment on Early Termination and on Certain  Extraordinary Events.  If in respect of the Transaction, an amount is payable by Dealer to Counterparty (i) pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or (ii) pursuant to Section 6(d)(ii) of the Agreement (any such amount, a “Payment Obligation”), then Dealer shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation, as applicable, of its election that the Share 

 

21











 

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, in good faith and in its reasonable discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.

 

	
Share Termination   Alternative:
    	
 
    	
If applicable, Dealer shall deliver to Counterparty   the Share Termination Delivery Property on, or within a commercially   reasonable period of time after, the date when the relevant Payment   Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of   the Equity Definitions or Section 6(d)(ii) and 6(e) of the   Agreement, as applicable, in satisfaction of such Payment Obligation in the   manner reasonably requested by Counterparty free of payment.
    
	
 
    	
 
    	
 
    
	
Share Termination   Delivery Property:
    	
 
    	
A number of Share Termination Delivery Units, as   calculated by the Calculation Agent, equal to the Payment Obligation divided   by the Share Termination Unit Price. The Calculation Agent shall adjust the   Share Termination Delivery Property by replacing any fractional portion of a   security therein with an amount of cash equal to the value of such fractional   security based on the values used to calculate the Share Termination Unit   Price.
    
	
 
    	
 
    	
 
    
	
Share Termination Unit   Price:
    	
 
    	
The value of property contained in one Share   Termination Delivery Unit, as determined by the Calculation Agent in its   discretion by commercially reasonable means and notified by the Calculation   Agent to Dealer at the time of notification of the Payment Obligation. For   the avoidance of doubt, the parties agree that in determining the Share   Termination Delivery Unit Price the Calculation Agent may consider, if commercially   reasonable, the purchase price paid in connection with the purchase of Share   Termination Delivery Property.
    
	
 
    	
 
    	
 
    
	
Share Termination   Delivery Unit:
    	
 
    	
One Share or, if the Shares have changed into cash   or any other property or the right to receive cash or any other property as   the result of a Nationalization, Insolvency or Merger Event (any such   cash or other property, the “Exchange Property”),   a unit consisting of the type and amount of such Exchange Property received   by a holder of one Share (without consideration of any requirement to pay   cash or other consideration in lieu of fractional amounts of any securities)   in such Nationalization, Insolvency or Merger Event, as determined by   the Calculation Agent.
    
	
 
    	
 
    	
 
    
	
Failure to Deliver:
    	
 
    	
Applicable
    
	
 
    	
 
    	
 
    
	
Other applicable   provisions:
    	
 
    	
If Share Termination Alternative is applicable, the   provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity   Definitions and the provisions set forth opposite the caption “Representation   and Agreement” in Section 2 will be applicable, except
    


 

22











 

	
 
    	
 
    	
that all references in such provisions to   “Physically-settled” shall be read as references to “Share Termination   Settled” and all references to “Shares” shall be read as references to “Share   Termination Delivery Units”.  “Share   Termination Settled” in relation to the Transaction means that the Share   Termination Alternative is applicable to the Transaction.
    


 

(l)                                     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.

 

(m)                             Registration.  Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer based on the advice of counsel, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of 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 of similar size; provided, however, that if Dealer, in its sole 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 of similar size, 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 commercially reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or (iii) purchase the Hedge Shares from Dealer at the Relevant Price on such Exchange Business Days, and in the amounts, requested by Dealer.

 

(n)                                 Tax Disclosure.
