Certain defined terms used herein have the meanings assigned to them in the Indenture to be dated as of June 3, 2014 between Counterparty and Wilmington Trust, National Association, as trustee (the “Base Indenture”), as supplemented by a supplemental indenture to be dated as of June 3, 2014 (the “Supplemental Indenture”, and the Base Indenture as so supplemented, the “Indenture”) relating to the USD125,000,000 principal amount of 2.75% Convertible Senior Notes due 2019 (the “Base Convertible Securities”) together with any 2.75% Convertible Senior Notes due 2019 that may be issued pursuant to the Underwriters’ option under the Underwriting Agreement (as defined below) (the “Optional Convertible Securities” and, together with the Base Convertible Securities, the “Convertible Securities”). In the event of any inconsistency between the terms defined in the Indenture and this Confirmation, this Confirmation shall govern. For the avoidance of doubt, references herein to sections of the Indenture are based on the draft of the Indenture most recently reviewed by the parties at the time of execution of this Confirmation.

The parties further acknowledge that references to the Indenture herein are references to the Indenture as in effect on the date of its execution and if the Indenture is, or the Convertible Securities are, amended, supplemented or modified following their execution, any such amendment, supplement or modification (other than (i) a Merger Supplemental Indenture (as defined below) and (ii) any amendment, supplement or modification pursuant to Section 9.01(m) of the Supplemental Indenture that, as determined by the Calculation Agent, conforms the Supplemental Indenture to the description of the Convertible Securities in the preliminary prospectus supplement related to the Convertible Securities, as supplemented by the pricing term sheet related to the Convertible Securities) will be disregarded for purposes of this Confirmation (other than as provided in Section 8(a)(i) below) unless the parties agree otherwise in writing.

All provisions contained in, or incorporated by reference to, the Agreement will govern this Confirmation except as expressly modified herein. In the event of any inconsistency between this Confirmation and either the Definitions or the Agreement, this Confirmation shall govern.

Delivery Obligation: In lieu of the obligations set forth in Sections 8.1 and 9.1 of the Equity Definitions, and subject to “Notice of Exercise” above, in respect of an Exercise Date occurring on a Conversion Date, Dealer will deliver to Counterparty, on the related Settlement Date, a number of Shares and/or amount of cash in USD equal to the product of (i) the Applicable Percentage and (ii) the aggregate number of Shares, if any, that Counterparty would be obligated to deliver to the holder(s) of the Relevant Convertible Securities converted on such Conversion Date pursuant to Section 12.02 of the Indenture and/or the aggregate amount of cash, if any, in excess of USD1,000 per Convertible Security (in denominations of USD1,000) that Counterparty would be obligated to deliver to holder(s) pursuant to Section 12.02 of the Indenture (except that such aggregate number of Shares shall be determined without taking into consideration any rounding pursuant to the proviso to Section 12.02(b) of the Indenture and shall be rounded down to the nearest whole number) and cash in lieu of fractional Shares, if any, resulting from such rounding, as if Counterparty had elected to satisfy its conversion obligation in respect of such Relevant Convertible Securities by the Convertible Security Settlement Method, as determined by the Calculation Agent by reference to such Sections of the Indenture, notwithstanding any different actual election by Counterparty with respect to the settlement of such Convertible Securities (the “Convertible Obligation”); provided that (i) if the Convertible Obligation exceeds the Capped Convertible Obligation, then the Delivery Obligation shall be the Capped Convertible Obligation; (ii) the Convertible Obligation (and, for the avoidance of doubt, the Capped Convertible Obligation) shall be determined (A) excluding any Shares and/or cash that Counterparty is obligated to deliver to holder(s) of the Relevant Convertible Securities as a result of any adjustments to the Conversion Rate pursuant to Section 12.03, 12.04(f) or 12.04(g) of the Indenture and (B) without regard to the election, if any, by Counterparty to adjust the Conversion Rate (and, for the avoidance of doubt, the Delivery Obligation shall not include any interest payment on the Relevant Convertible Securities that Counterparty is (or would have been) obligated to deliver to holder(s) of the Relevant Convertible Securities for such Conversion Date); and (iii) if such exercise relates to the conversion of Relevant Convertible Securities in connection with which holders thereof are entitled to receive additional Shares and/or cash pursuant to the adjustment to the Conversion Rate set forth in Section 12.03 of the Indenture, then, notwithstanding the foregoing, the Delivery Obligation shall include the Applicable Percentage of such additional Shares and/or cash (as determined by the Calculation Agent by reference to such Section of the Indenture), except that the Delivery Obligation shall be capped so that the value of the Delivery Obligation per Option (with the value of any Shares included in the Delivery Obligation determined by the Calculation Agent using a commercially reasonable market price per Share (which may, for the avoidance of doubt, be the VWAP Price (as defined below) over the relevant “Observation Period”, or any portion thereof, applicable to the relevant Convertible Security Settlement Method) does not exceed

5

	the amount as determined by the Calculation Agent that would be payable by Dealer pursuant to Section 6 of the Agreement if such Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction (except that, for purposes of determining such amount (x) the Number of Options shall be deemed to be equal to the number of Options exercised on such Exercise Date, (y) such amount payable will be determined as if Section 12.03 of the Indenture were deleted and (z) if the related Conversion Date occurs on or after the first day of the “Observation Period” that applies to the relevant Convertible Security Settlement Method, the Calculation Agent shall have the right to adjust the Delivery Obligation as appropriate to reflect the additional costs (including, but not limited to, hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities (including the unwinding of any hedge position) as a result of such event, with such adjustments made assuming Dealer maintains a commercially reasonable hedge position) was the sole Affected Transaction and Counterparty was the sole Affected Party (determined without regard to Section 8(b) of this Confirmation), it being understood that the cap described in this clause (iii) is in addition to, and cumulative with, clauses (i) and (ii) of this proviso. Notwithstanding the foregoing, and in addition to the caps described in clauses (i), (ii) and (iii) of the proviso above, in all events the Delivery Obligation shall be capped so that the value of the Delivery Obligation does not exceed the value of the ratio the numerator of which is the Convertible Obligation (with the Convertible Obligation determined based on the actual settlement method elected by Counterparty with respect to such Relevant Convertible Securities instead of the Convertible Security Settlement Method and with the value of any Shares included in either the Delivery Obligation or such Convertible Obligation determined by the Calculation Agent using the VWAP Price (as defined below) on the Scheduled Trading Day immediately preceding the Settlement Date as commercially reasonably determined by the Calculation Agent) and the denominator of which is the aggregate of all Applicable Percentages under all outstanding Capped Call Transactions in respect of Convertible Securities as of the time of such calculation.
Capped Convertible Obligation:	In respect of an Exercise Date occurring on a Conversion Date, the Convertible Obligation that would apply if, solely for purposes of calculating the “Daily Conversion Value” (as defined in the Indenture), the “Daily VWAP” for each “VWAP Trading Day” in the “Observation Period” (each as defined in the Indenture) or, if applicable, the assumed “Observation Period” specified in clause (ii) of “Convertible Security Settlement Method” below, were the lesser of (x) the Cap Price and (y) the actual “Daily VWAP” for such “VWAP Trading Day” as defined in the Indenture.
Convertible Security Settlement Method:	For any Relevant Convertible Securities, if Counterparty has notified Dealer in the related Notice of Exercise (or in the Notice of Convertible Security Settlement Method, as the case may be) that it has elected to satisfy its conversion obligation in respect of such Relevant Convertible Securities in cash or in a combination of cash and Shares in accordance with Section 12.02(a) of the

6

	Indenture (a “Cash Election”) with a “Specified Dollar Amount” (as defined in the Indenture) of at least USD1,000, the Convertible Security Settlement Method shall be the settlement method actually so elected by Counterparty in respect of such Relevant Convertible Securities; otherwise, the Convertible Security Settlement Method shall (i) assume Counterparty made a Cash Election with respect to such Relevant Convertible Securities with a “Specified Dollar Amount” (as defined in the Indenture) of USD1,000 per Relevant Convertible Security and (ii) be calculated as if the relevant “Observation Period” (as defined in the Indenture) pursuant to Section 12.02(b)(iii) of the Indenture consisted of 160 VWAP Trading Days commencing on the 162nd “Scheduled Trading Day” prior to the “Maturity Date” (each as defined in the Indenture).
Notice of Delivery Obligation:	No later than the Scheduled Trading Day immediately following the last day of the relevant Observation Period, Counterparty shall give Dealer notice of the aggregate number of Shares and/or amount of cash comprising the Convertible Obligations for all Relevant Convertible Securities (it being understood, for the avoidance of doubt, that the requirement of Counterparty to deliver such notice shall not limit Counterparty’s obligations with respect to Notice of Exercise or Notice of Convertible Security Settlement Method or Dealer’s obligations with respect to Delivery Obligation, each as set forth above, in any way).
Other Applicable Provisions:	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9 and 9.11 (except that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by excluding any representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws arising as a result of the fact that Counterparty is the Issuer of the Shares) of the Equity Definitions will be applicable as if “Physical Settlement” applied to the Transaction.
Restricted Certificated Shares:	Notwithstanding anything to the contrary in the Equity Definitions, Dealer may, in whole or in part, deliver Shares required to be delivered to Counterparty hereunder in certificated form in lieu of delivery through the Clearance System. With respect to such certificated Shares, the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by deleting the remainder of the provision after the word “encumbrance” in the fourth line thereof.
Share Adjustments:
Method of Adjustment:	Notwithstanding Section 11.2 of the Equity Definitions, upon the occurrence of any event or condition set forth in Sections 12.04(a)-(e) or 12.05 of the Indenture that the Calculation Agent determines reasonably in good faith would result in an adjustment under the Indenture by reference to such Sections thereof (any such event or condition, an “Adjustment Event”), the Calculation Agent shall make a corresponding adjustment to the terms relevant to the exercise, settlement or payment of the Transaction, subject to “Discretionary Adjustments” below. Immediately upon the occurrence of any Adjustment Event, Counterparty shall notify the Calculation Agent of such Adjustment Event; and once the

7

	adjustments to be made to the terms of the Indenture and the Convertible Securities in respect of such Adjustment Event have been determined, Counterparty shall immediately notify the Calculation Agent in writing of the details of such adjustments. For the avoidance of doubt, for purposes of any Adjustment Event under Section 12.05 of the Indenture, the Calculation Agent may take into account Dealer’s commercially reasonable Hedge Positions and the Observation Period applicable to the relevant Convertible Security Settlement Method.
	For the avoidance of doubt, Dealer shall not have any payment or delivery obligation hereunder in respect of, and no adjustment shall be made to the terms of the Transaction on account of, (x) any distribution of cash, property or securities by Counterparty to the holders of Convertible Securities (upon conversion or otherwise) or (y) any other transaction in which holders of Convertible Securities are entitled to participate, in each case, in lieu of an adjustment under the Indenture in respect of an Adjustment Event (including, without limitation, under the last sentence of the second paragraph of Section 12.04(c) of the Indenture or the last sentence of the second paragraph of Section 12.04(d) of the Indenture).
Discretionary Adjustments:	Notwithstanding anything to the contrary herein or in the Equity Definitions, if the Calculation Agent in good faith disagrees with any adjustment under the Indenture that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation, pursuant to Section 12.05 of the Indenture or pursuant to Section 12.06 of the Indenture or any supplemental indenture entered into thereunder (a “Merger Supplemental Indenture”) or in connection with any proportional adjustment or the determination of the fair value of any securities, property, rights or other assets), then 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 of or under the Transaction in a commercially reasonable manner.

Consequences of Merger Eventsand Tender Offer:	Notwithstanding Sections 12.2 and 12.3 of the Equity Definitions, upon the occurrence of a Merger Event that the Calculation Agent determines reasonably in good faith by reference to Section 12.06 of the Indenture would result in an adjustment under the Indenture, the Calculation Agent shall make a corresponding adjustment to the terms relevant to the exercise, settlement or payment of the Transaction, subject to “Discretionary Adjustments” above; provided that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to Section 12.03, 12.04(f) or 12.04(g) of the Indenture and the election, if any, by Counterparty to adjust the Conversion Rate; and provided further that the Calculation Agent may limit or alter any such adjustment referenced in this paragraph so that the fair value of the

8

	Transaction to Dealer (taking into account a commercially reasonable hedge position) is not adversely affected as a result of such adjustment; and provided further that if, with respect to a Merger Event, (A) 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 organized under the laws of the United States, any State thereof or the District of Columbia, or (B) the Counterparty to the Transaction following such Merger Event will not be a corporation or will not be the Issuer following such Merger Event, Dealer may elect in its sole discretion that Cancellation and Payment (Calculation Agent Determination) shall apply.
Consequences of Announcement Events:	Modified Calculation Agent Adjustment as set forth in Section 12.3(d) of the Equity Definitions; provided that (i) the Calculation Agent may not adjust any term of the Transaction other than the Cap Price on account of an Announcement Event, (ii) references to “Tender Offer” shall be replaced by references to “Announcement Event” and references to “Tender Offer Date” shall be replaced by references to “date of such Announcement Event” and (iii) in no event shall the Cap Price be less than the Strike Price. An Announcement Event shall be an “Extraordinary Event” for purposes of the Equity Definitions, to which Article 12 of the Equity Definitions is applicable.

For purposes of this definition of “Announcement Event,” the remainder of the definition of “Merger Event” in Section 12.1(b) of the Equity Definitions following the definition of “Reverse Merger” therein shall be disregarded.
Adjustments to Cap Price:	Upon the occurrence of a Merger Date or Tender Offer Date, or the declaration by Counterparty of the terms of any Potential Adjustment Event (as such terms are defined in the Equity Definitions, as amended herein) or upon the occurrence of any Adjustment Event, the Calculation Agent may, in its commercially reasonable discretion, adjust the Cap Price as it determines appropriate to account for the effect of the relevant Merger Event, Tender Offer or Potential Adjustment Event (as such terms are defined in the Equity Definitions, as amended herein) or Adjustment Event; provided that in no event shall the Cap Price be less than the Strike Price.

9

(iii) On the Trade Date and on each day during the Observation Period and any deemed Observation Period as set forth herein applicable to the Relevant Convertible Securities and any Early Termination Period, neither Counterparty nor any “affiliated purchaser” (each as defined in Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall directly or indirectly (including, without limitation, by means of any cash-settled or other derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or commence any tender offer relating to, any Shares (or an equivalent interest, including a unit of beneficial interest in a trust or limited partnership or a depository share) or any security convertible into or exchangeable or exercisable for Shares; provided that the foregoing shall not limit Counterparty’s ability, pursuant to any plan (as defined in Rule 10b-18) of Counterparty, to re-acquire Shares in connection with any equity transaction related to such plan or limit Counterparty’s ability to withhold Shares to cover tax liabilities associated with such equity

12

transactions or otherwise restrict Counterparty’s ability to repurchase Shares under privately negotiated transactions with any of its employees, officers, directors or affiliates, so long as (i) any re-acquisition, withholding or repurchase does not constitute a “Rule 10b-18 purchase” (as defined in Rule 10b-18) and (ii) no such transaction directly or indirectly involves or results in a purchase of Shares on the Exchange.

(iv) Without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that Dealer is not making any representations or warranties or taking any position or expressing any view with respect to the treatment of the Transaction under any accounting standards including ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, or ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity (or any successor issue statements) or under FASB’s Liabilities & Equity Project.

(vi) Prior to the Trade Date, Counterparty shall deliver to Dealer a resolution of Counterparty’s board of directors authorizing the Transaction and such other certificate or certificates as Dealer shall reasonably request.

(viii) Counterparty is not, and after giving effect to 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.

(ix) On each of the Trade Date and the Premium Payment Date, Counterparty is not, or will not be, “insolvent” (as such term is defined under Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)) and Counterparty would be able to purchase the Shares hereunder in compliance with the laws of the jurisdiction of its incorporation.

(x) Counterparty is not aware based on due inquiry of any state or local (including non-U.S. jurisdictions) law, rule, regulation or regulatory order applicable to the Shares that 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.

(xi) The representations and warranties of Counterparty set forth in Section 3 of the Agreement and Section 1(a) of the Underwriting Agreement dated as of May 29, 2014 between Counterparty and Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC as representatives of the Underwriters party thereto (the “Underwriting Agreement”) are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein.

(xii) Counterparty understands no obligations of Dealer to it hereunder will be entitled to the benefit of deposit insurance and that such obligations will not be guaranteed by any affiliate of Dealer or any governmental agency.

(xiii) 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.

(b) Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” as defined in Section 1a(18) of the U.S. Commodity Exchange Act, as amended.

(c) Each of Dealer and Counterparty acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), by virtue of Section 4(a)(2) thereof. Accordingly, Counterparty represents and warrants to Dealer that (i) it has the financial ability to bear the economic risk of its investment in the Transaction and is able to bear a total loss of its investment, (ii) it is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act, (iii) it is entering into the Transaction for its own account and without a view to the distribution or resale thereof, and (iv) the assignment, transfer or other disposition of the Transaction has not been and will not be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state securities laws.

(d) Counterparty agrees and acknowledges that Dealer is a “financial institution” and “financial participant” within the meaning of Sections 101(22) and 101(22A) of the Bankruptcy Code. The parties hereto further agree and acknowledge that it is the intent of the parties that (A) this Confirmation is a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “settlement payment” within the meaning of Section 546 of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “transfer,” as such term is defined in Section 101(54) of the Bankruptcy Code and a “payment or other transfer of property” within the meaning of Sections 362 and 546 of the Bankruptcy Code, and (B) Dealer is entitled to the protections afforded by, among other sections, Sections 362(b)(6), 362(b)(27), 362(o), 546(e), 546(j), 548(d)(2), 555 and 561 of the Bankruptcy Code.

(e) Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Effective Date and reasonably acceptable to Dealer in form and substance, with respect to the matters set forth in Section 3(a) of the Agreement and Section 7(a)(viii) hereof.

8. Other Provisions:

(a) Additional Termination Events.

(i) The occurrence of (A) an “Event of Default” with respect to Counterparty under the terms of the Convertible Securities as set forth in Section 6.01 of the Indenture that results in the Convertible Securities becoming or being declared due and payable pursuant to the terms of the Indenture, (B) an Amendment Event or (C) an Excluded Conversion Event shall be an Additional Termination Event with respect to which the Transaction is the sole Affected Transaction and Counterparty is the sole Affected Party, and Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement; provided that in the case of an Excluded Conversion Event the Transaction shall be subject to termination only in respect of a number of Options equal to the number of Convertible Securities that cease to be outstanding in connection with or as a result of such Excluded Conversion Event. For the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction pursuant to Section 6 of the Agreement in connection with an Excluded Conversion Event, the Calculation Agent shall assume that (x) the relevant Excluded Convertible Securities shall not have been converted and remain outstanding, and (y) in the case of an Induced Conversion, any adjustments, agreements, additional payments, deliveries or acquisitions by or on behalf of Counterparty or any affiliate of Counterparty in connection therewith had not occurred.

14

“Amendment Event” means that Counterparty amends, modifies, supplements, waives or obtains a waiver in respect of any term of the Indenture or the Convertible Securities (i) governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption right of Counterparty, any term relating to conversion of the Convertible Securities (including changes to the conversion rate, conversion rate adjustment provisions, conversion settlement dates or conversion conditions), (other than any amendment, supplement or modification pursuant to Section 9.01(m) of the Supplemental Indenture that, as determined by the Calculation Agent, conforms the Supplemental Indenture to the description of the Convertible Securities in the preliminary prospectus supplement related to the Convertible Securities, as supplemented by the pricing term sheet related to the Convertible Securities) or (ii) any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Securities to amend, in each case without the consent of Dealer, such consent not to be unreasonably withheld or delayed (it being understood that Dealer may take into account the cumulative effect of any such amendment, modification, supplement or waiver, or series thereof, and will not be required to consent to any such change that Dealer determines could adversely impact its Hedging Activities or result in an Additional Disruption Event or Excess Ownership Position).

“Excluded Conversion Event” means any conversion of any Excluded Convertible Securities.

“Induced Conversion” means a conversion of any Excluded Convertible Securities (A) in connection with (x) an adjustment to the Conversion Rate effected by Counterparty (whether pursuant to Section 12.04(f) of the Indenture or otherwise) that is not required under the terms of the Indenture or (y) an agreement by Counterparty with the holder(s) of such Convertible Securities whereby, in the case of either (x) or (y), the holder(s) of such Convertible Securities receive upon conversion or pursuant to such agreement, as the case may be, a payment of cash or delivery of Shares or any other property or item of value that was not required under the terms of the Indenture or (B) after having been acquired from a holder of Convertible Securities by or on behalf of Counterparty or any of its affiliates other than pursuant to a conversion by such Holder and thereafter converted by or on behalf of Counterparty or any affiliate of Counterparty.

(ii) (A) Promptly following any Repayment Event (as defined below) (but, in any event, within 5 Scheduled Trading Days following settlement thereof), Counterparty may notify Dealer of such Repayment Event and the aggregate principal amount of Convertible Securities subject to such Repayment Event (the “Repayment Convertible Securities”) (any such notice, a “Repayment Notice”). The receipt by Dealer from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section 8(a).

(B) Upon receipt of any such Repayment Notice, Dealer shall designate an Exchange Business Day following receipt of such Repayment Notice 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 (i) the number of Repayment Convertible Securities in denominations of USD1,000 that are subject to the relevant Repayment Event and (ii) the Number of Options as of the date Dealer designates such Early Termination Date, and as of such date, the Number of Options shall be reduced by the number of 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 and, if applicable, Section 8(b). 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 Securities are repurchased by Counterparty or any of its subsidiaries, (ii) any Convertible Securities 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 Securities is repaid prior to the final maturity date of the Convertible Securities (other than upon acceleration of the Convertible Securities described in Section 8(a)(i)(A)), or (iv) any Convertible Securities 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

15

to any exchange offer or similar transaction; provided that a conversion of Convertible Securities pursuant to the terms of the Indenture shall not 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 in respect of a Repayment Event, including, without limitation, the delivery of a Repayment Notice, which shall be deemed to be a remaking by Counterparty of the representation set forth in Section 7(a)(i) as of the date of such delivery.

(D) Counterparty shall cause any Convertible Securities subject to a Repayment Event to be promptly cancelled and acknowledges and agrees that, except to the extent provided above in this Section 8(a)(ii), all such Convertible Securities subject to a Repayment Event will be deemed for all purposes under the Transaction to be permanently extinguished and no longer outstanding.

(b) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If Dealer shall owe Counterparty any amount pursuant to “Consequences of Merger Events and Tender Offer” above or Sections 12.6, 12.7 or 12.9 of the Equity Definitions or pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Counterparty shall have the right, in its sole discretion, to require Dealer to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 9:30 A.M. New York City time on the relevant merger date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable (“Notice of Share Termination”); provided that if Counterparty does not elect to require Dealer to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to elect to satisfy its Payment Obligation by the Share Termination Alternative, notwithstanding Counterparty’s failure to elect or election to the contrary; and provided further that Counterparty shall not have the right to so elect (but, for the avoidance of doubt, Dealer shall have the right to so elect) in the event (i) of an Insolvency, a Nationalization or a Merger Event, in each case, in which the consideration or proceeds to be paid to holders of Shares consists solely of cash, (ii) of an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the sole Affected Party or Extraordinary Event, which Event of Default, Termination Event or Extraordinary Event resulted from an event or events within Counterparty’s control or (iii) that Counterparty fails to remake the representation set forth in Section 7(a)(i) as of the date of such election. Upon such Notice of Share Termination, the following provisions shall apply on the Scheduled Trading Day immediately following the relevant merger date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable:

Share Termination Alternative:	If applicable, means that Dealer shall deliver to Counterparty the Share Termination Delivery Property on the date on which the Payment Obligation would otherwise be due pursuant to “Consequences of Merger Events and Tender Offer” above, Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, or such later date or dates as the Calculation Agent may reasonably determine (the “Share Termination Payment Date”), in satisfaction of the Payment Obligation.
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 the aggregate amount 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 on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, 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.

16

Share Termination Delivery Unit:	In the case of a Termination Event, Event of Default, Delisting or Additional Disruption Event, one Share or, in the case of an Insolvency, Nationalization or Merger Event, one Share or a unit consisting of the number or amount of each type of 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 Insolvency, Nationalization or Merger Event, as applicable. If such Insolvency, Nationalization or Merger Event involves a choice of consideration to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.
Failure to Deliver:	Applicable
Other applicable provisions:	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (except that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by excluding any representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws arising as a result of the fact that Counterparty is the issuer of the Shares or any portion of the Share Termination Delivery Units) of the Equity Definitions will be applicable as if “Physical Settlement” applied to the Transaction, except that all references to “Shares” shall be read as references to “Share Termination Delivery Units.”

(c) Disposition of Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer based on advice of counsel, any Shares (the “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: (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act to cover the resale of such Hedge Shares and (A) enter into an agreement substantially similar to underwriting agreements customary for underwritten offerings of equity securities of similar size issued by companies of comparable size, maturity and lines of business as Counterparty, in form and substance reasonably satisfactory to Dealer, (B) provide accountant’s “comfort” letters in customary form for registered offerings of equity securities, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities and (E) afford Dealer a reasonable opportunity to conduct a “due diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities; 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 Section 8(c) 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 issued by companies of comparable size, maturity and lines of business as Counterparty, in form and substance reasonably satisfactory to Dealer, including customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Hedge Shares from Dealer), opinions and certificates and such other documentation as is customary for private placements agreements, all reasonably acceptable to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its 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 VWAP Price on such Exchange Business Days, and in the amounts, requested by Dealer. “VWAP Price” means, on any Exchange Business Day, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg Screen REGI <Equity> VAP (or any successor thereto) in respect of the period from 9:30 a.m. to 4:00 p.m. (New York City time) on such Exchange Business Day (or if such volume-weighted average price is

17

unavailable or is manifestly incorrect or there occurs a “VWAP Market Disruption Event” (as defined in the Indenture), the market value of one Share on such Exchange Business Day, as determined by the Calculation Agent using a volume-weighted method).

(d) Amendment to Equity Definitions. The following amendment shall be made to the Equity Definitions:

(i) Section 11.2(e)(vii) of the Equity Definitions is hereby amended by deleting the words “diluting or concentrative” and replacing them with “material” and adding the phrase “or options on the Shares” at the end of the sentence; and

(ii) 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.”

(e) Repurchase and Conversion Rate Adjustment Notices. Counterparty shall, at least two Scheduled Trading Days prior to effecting any repurchase of Shares or consummating or otherwise executing or engaging in any transaction or event (a “Conversion Rate Adjustment Event”) that would lead to an increase in the Conversion Rate (as such term is defined in the Indenture), give Dealer a written notice of such repurchase or Conversion Rate Adjustment Event (a “Repurchase Notice”) if, following such repurchase or Conversion Rate Adjustment Event, the Notice Percentage as determined on the date of such Repurchase Notice is (i) greater than 4.5% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the Notice Percentage as of the date hereof), and, if such repurchase or Conversion Rate Adjustment Event, or the intention to effect the same, would constitute material non-public information with respect to Counterparty or the Shares, Counterparty shall make public disclosure thereof at or prior to delivery of such Repurchase Notice. The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the Number of Shares plus the number of Shares underlying any other call options sold by Dealer to Counterparty and the denominator of which is the number of Shares outstanding on such day. In the event that Counterparty fails to provide Dealer with a Repurchase Notice on the day and in the manner specified in this Section 8(e) then Counterparty agrees to indemnify and hold harmless Dealer, its affiliates and their respective directors, officers, employees, agents and controlling persons (Dealer and each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws, including without limitation, Section 16 of the Exchange Act, relating to or arising out of such failure. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified Party for all expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Counterparty) in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. This indemnity shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement shall inure to the benefit of any permitted assignee of Dealer.

(f) Transfer and Assignment. Either party may transfer any of its rights or obligations under the Transaction with the prior written consent of the non-transferring party, such consent not to be unreasonably withheld or delayed. For the avoidance of doubt, Dealer may condition its consent on any of the following, without limitation: (i) the receipt by Dealer of opinions and documents reasonably satisfactory to Dealer in connection with such assignment, (ii) such assignment being effected on terms reasonably satisfactory to Dealer with respect to any legal and regulatory requirements relevant to Dealer, (iii) Counterparty continuing to be obligated to provide notices hereunder relating to the Convertible Securities and continuing to be obligated with respect to “Disposition of Hedge Shares” and “Repurchase Notices” above, (iv) payment by Counterparty of all

18

reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such assignment, (v) Dealer not being obliged, as a result of such assignment, to pay the assignee on any payment date, an amount greater than Dealer would have been required to pay in the absence of such assignment and (vi) no Event of Default, Potential Event of Default or Termination Event occurring as a result of such assignment. In addition, Dealer may transfer or assign without any consent of Counterparty its rights and obligations hereunder and under the Agreement, in whole or in part, to any of its affiliates (i) if such affiliate or its guarantor of its obligations hereunder has a rating for its long-term, unsecured and unsubordinated indebtedness that is equal to or higher than that of Dealer, as rated by either Moody’s or Standard and Poor’s or (ii) whose obligations hereunder will be guaranteed by Dealer or Dealer’s ultimate parent entity, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions. At any time at which any Excess Ownership Position or a Hedging Disruption exists, if Dealer, in its discretion, is unable to effect a transfer or assignment to a third party in accordance with the requirements set forth above after using its commercially reasonable efforts on pricing terms and within a time period reasonably acceptable to Dealer such that an Excess Ownership Position or a Hedging Disruption, as the case may be, no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of the Transaction, such that such Excess Ownership Position or Hedging Disruption, as the case may be, no longer exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment or delivery shall be made pursuant to Section 6 of the Agreement and Section 8(b) of this Confirmation as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion of the Transaction, (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction shall be the only Terminated Transaction. “Excess Ownership Position” means any of the following: (i) the Equity Percentage exceeds 7.5%, (ii) Dealer or any “affiliate” or “associate” of Dealer would own in excess of 13% of the outstanding Shares for purposes of Section 203 of the Delaware General Corporation Law or (iii) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a “Dealer Person”) under any federal, state or local laws, regulations, regulatory orders or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting or registration obligations (except for any filings of Form 13F, Schedule 13D or Schedule 13G under the Exchange Act) or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under Applicable Laws, as determined by Dealer in its reasonable discretion, and with respect to which such requirements have not been met or the relevant approval has not been received or that would give rise to any consequences under the constitutive documents of Counterparty or any contract or agreement to which Counterparty is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination. The “Equity 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 which Dealer is or may be deemed to be a part (Dealer and any such affiliates, persons and groups, collectively, “Dealer Group”) beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such number) and (B) the denominator of which is the number of Shares outstanding on such day.

(g) Staggered Settlement. If Dealer reasonably determines it is appropriate with respect to any applicable legal, regulatory or self-regulatory requirements (including any requirements relating to Dealer’s hedging activities with respect to the Transaction), and/or to avoid an Excess Ownership Position, Dealer may, by notice to Counterparty on or prior to any Settlement Date or other date of Delivery (a “Nominal Settlement Date”), elect to deliver the Shares or Share Termination Delivery Units on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows:

(i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date, but not prior to the beginning of the related Observation Period that applies to the Convertible Security Settlement Method or the Early Termination Date, as applicable) or delivery times and how it will allocate the Shares or Share Termination Delivery Units it is required to deliver under “Delivery Obligation” (above) among the Staggered Settlement Dates or delivery times; and

19

(ii) the aggregate number of Shares or Share Termination Delivery Units that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares or Share Termination Delivery Units that Dealer would otherwise be required to deliver on such Nominal Settlement Date.

(h) Right to Extend. Dealer may postpone or add, in whole or in part, any Exercise Date or Settlement Date or any other date of valuation or delivery by Dealer, with respect to some or all of the relevant Options (in which event the Calculation Agent shall make appropriate adjustments to the Delivery Obligation or Payment Obligation, as applicable), if Dealer determines, in its good faith, commercially reasonable discretion and based on advice of counsel in the case of the immediately following clause (ii), that such extension is reasonably necessary or appropriate (i) to preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions in the cash market, the stock loan market or any other relevant market (but only if there has been a material decline in such liquidity conditions since the Trade Date as determined by the Calculation Agent) or (ii) to enable Dealer to effect transactions in Shares in connection with its 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 (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer in good faith in relation to such requirements).

(i) Adjustments. For the avoidance of doubt, whenever the Calculation Agent is called upon to make an adjustment pursuant to the terms of this Confirmation or the Definitions to take into account the effect of an event, the Calculation Agent 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.

(j) 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.

(k) [Reserved]

(l) No Netting and Set-off. Each party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable law or otherwise.

(m) Equity Rights. Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights with respect to the Transaction that are senior to the claims of common stockholders in the event of Counterparty’s bankruptcy. For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than during Counterparty’s bankruptcy to any claim arising as a result of a breach by Counterparty of any of its obligations under this Confirmation or the Agreement. For the avoidance of doubt, the parties acknowledge that this Confirmation is not secured by any collateral that would otherwise secure the obligations of Counterparty herein under or pursuant to any other agreement.

(n) Early Unwind. In the event the sale by Counterparty of the Base Convertible Securities is not consummated with the underwriters pursuant to the Underwriting Agreement for any reason by the close of business in New York on June 3, 2014 (or such later date as agreed upon by the parties, which in no event shall be later than June 17, 2014) (June 3, 2014 or such later date being 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 thereunder shall be cancelled and terminated and (ii) except to the extent that the Early Unwind Date occurred as a result of a breach of the Underwriting Agreement by Dealer (or its affiliate, as applicable) in its capacity as underwriter, Counterparty shall pay to

20

Dealer an amount in cash equal to the aggregate amount of costs and expenses relating to the unwinding of Dealer’s hedging activities in respect of the Transaction (including market losses incurred in reselling any Shares purchased by Dealer or its affiliates in connection with such hedging activities) or, at the election of Counterparty, deliver to Dealer Shares with a value equal to such amount, as commercially reasonably determined by the Calculation Agent, in which event (x) the parties shall enter into customary and commercially reasonable documentation relating to the registered or exempt resale of such Shares and (y) Counterparty shall remake the representation set forth in Section 7(a)(i) as of the date of such election; provided that, if Counterparty makes such election to deliver Shares, notwithstanding the foregoing, the number of Shares so delivered will not exceed a number of Shares equal to two multiplied by the Number of Shares (with such Number of Shares determined, for the avoidance of doubt, as if the relevant Convertible Securities had been issued). Following such termination, cancellation and (if applicable) payment or delivery, 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 either party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date. Dealer and Counterparty represent and acknowledge to the other that upon an Early Unwind and following the payment or delivery (if applicable) referred to above, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

(o) Wall Street Transparency and Accountability Act of 2010. The parties hereby agree that none of (v) Section 739 of the Wall Street Transparency and Accountability Act of 2010 (“WSTAA”), (w) any similar legal certainty provision in any legislation enacted, or rule or regulation promulgated, on or after the Trade Date, (x) the enactment of WSTAA or any regulation under the WSTAA, (y) any requirement under WSTAA nor (z) an amendment made by WSTAA, shall limit or otherwise impair either party’s 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)).

(p) Tax Matters.

(i) Withholding Tax imposed on payments to non-US counterparties under the United States Foreign Account Tax Compliance Act. “Tax” and “Indemnifiable Tax”, each 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.

(ii) HIRE Act. “Tax” and “Indemnifiable Tax”, each 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.

(iii) Tax documentation. Counterparty shall provide to Dealer, and Dealer shall provide to Counterparty, a valid U.S. Internal Revenue Service Form W-9, or any successor thereto, (i) on or before the date of execution of this Confirmation and (ii) promptly upon learning that any such tax form previously provided by Counterparty has become obsolete or incorrect. Additionally, Counterparty shall, promptly upon request by Dealer, provide such other applicable tax forms and documents requested by Dealer, and Dealer shall, promptly upon reasonable request by Counterparty, provide such other applicable tax forms and documents reasonably requested by Counterparty.

(iv) Tax Representations. Counterparty is a corporation for U.S. federal income tax purposes and is organized under the laws of the State of Delaware. Counterparty 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 and an exempt recipient under Treasury Regulation Section 1.6049-4(c)(1)(ii).

(q) Waiver of Trial by Jury. EACH OF COUNTERPARTY AND DEALER HEREBY IRREVOCABLY WAIVES (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS) ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THE TRANSACTION OR THE ACTIONS OF DEALER OR ITS AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF.

(r) Governing Law; Jurisdiction. THIS CONFIRMATION AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS CONFIRMATION SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS.
