This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the ISDA 2002 Master Agreement (the “Agreement”) as if Dealer and Company had executed an agreement in such form (but without any Schedule except for the election of (i) the laws of the State of New York as the governing law (without reference to choice of law doctrine other than Sections 5-1401 and 5-1402 of the General Obligations Law)) on the Trade Date and (ii) US Dollars as the Termination Currency.

Each of the representations and warranties of Company set forth in Section 3 of the Purchase Agreement (the “Purchase Agreement”), dated as of June 6, 2018, between Company and Dealer, as representative of the Initial Purchasers party thereto (the “Initial Purchaser”), are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein. Company hereby further represents and warrants to Dealer on the date hereof, on and as of the Premium Payment Date and, in the case of the representations in Section 8(d), at all times until termination of the Transaction, that:

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, such Indemnified Person shall promptly notify Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. Company shall be relieved from liability to the extent that any Indemnified Person fails promptly to notify Company of any action commenced against it in respect of which indemnity may be sought hereunder to the extent Company is materially prejudiced as a result thereof. Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Company shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding 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 Company under such paragraph, 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 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.

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 Terminated Portion, 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 Warrants equal to the number of Warrants underlying the Terminated Portion, (2) Company 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(j) shall apply to any amount that is payable by Company to Dealer pursuant to this sentence as if Company was not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Warrant 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 Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants purchased by Dealer from Company, 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 Company that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that, in Dealer's reasonable judgment based on advice of counsel, could give rise to reporting or registration obligations (except for filings on Form 13F, Schedule 13D or Schedule 13G) or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding. 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 Company, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or 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 Company to the extent of any such performance. Dealer shall provide Company with written notice of any transfer or assignment on the date of or as promptly as practicable after the date of such transfer or assignment.

Agent shall have no responsibility, obligation or liability, by way of issuance, guaranty, endorsement or otherwise in any manner with respect to the performance of either party under the Transaction, (iv) Dealer and the Agent have not given, and Counterparty is not relying (for purposes of making any investment decision or otherwise) upon, any statements, opinions or representations (whether written or oral) of Dealer or the Agent, other than the representations expressly set forth in this Confirmation or the Agreement, and (v) each party agrees to proceed solely against the other party, and not the Agent, to collect or recover any money or securities owed to it in connection with the Transaction. Counterparty acknowledges that the Agent is an affiliate of Dealer. Dealer will be acting for its own account in respect of this Confirmation and the Transaction contemplated hereunder.

events outside Company’s control), and if Company would owe any amount to Dealer pursuant to Section 6(d)(ii) of the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Company shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Company gives irrevocable telephonic notice to Dealer 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, confirmed in writing within one Scheduled Trading Day, of its election that the Share Termination Alternative shall not apply, (b) Company remakes the representation set forth in Section 8(g) as of the date of such election and (c) Dealer agrees, in its sole discretion, to such election, in which case the provisions of Section 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.

Notwithstanding anything to the contrary in this Confirmation, any Payment Obligation under this Confirmation shall, for all purposes, be calculated as if the Maximum Number of Shares were equal to two times the Number of Shares (without regard to the limitations on adjustment set forth in the second paragraph opposite the caption “Maximum Number of Shares” in Section 2) but any deliveries under Section 9(j)(i) shall be limited to the Maximum Number of Shares as defined in Section 2 hereof.

holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.

Company, unless Dealer waives the need for registration/private placement procedures set forth in (i) and (ii) below. Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants exercised or deemed exercised on any Expiration Date, if Dealer notifies Company of the need for registration or private placement procedures set forth in this Section 9(k), then Company shall elect, prior to the first Settlement Date for the first applicable Expiration Date, a Private Placement Settlement or Registration Settlement for all deliveries of Restricted Shares for all such Expiration Dates which election shall be applicable to all remaining Settlement Dates for such Warrants and the procedures in clause (i) or clause (ii) below shall apply for all such delivered Restricted Shares on an aggregate basis commencing after the final Settlement Date for such Warrants. The Calculation Agent shall make commercially reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a single Private Placement or Registration Settlement for such aggregate Restricted Shares delivered hereunder.

Restricted Shares pursuant to such registration statement during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Restricted Shares (which, for the avoidance of doubt, shall be (x) the Share Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to Section 9(j) above or (y) the Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on the Exchange Business Day on which Dealer, acting in a commercially reasonable manner, completes the sale of all Restricted Shares or, in the case of settlement of Share Termination Delivery Units, a sufficient number of Restricted Shares so that the realized net proceeds of such sales equals or exceeds the Payment Obligation (as defined above). If the Payment Obligation exceeds the realized net proceeds from such resale, Company shall transfer to Dealer by the open of the regular trading session on the Exchange on the Exchange Business Day immediately following such resale the amount of such excess (the “Additional Amount”) in cash or in a number of Shares (“Make-whole Shares”) in an amount that, based on the Settlement Price on such day (as if such day was the “Valuation Date” for purposes of computing such Settlement Price), has a dollar value equal to the Additional Amount. The Resale Period shall continue to enable the sale of the Make-whole Shares. If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration Settlement shall apply. This provision shall be applied successively until the Additional Amount is equal to zero. In no event shall Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

Share Limit. If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Company’s obligation to make such delivery shall not be extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after, Dealer gives notice to Company that, after such delivery, (i) the Section 16 Percentage would not exceed 8.5%, and (ii) the Share Amount would not exceed the Applicable Share Limit.

of Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Settlement Prices; and (D) any market activities of Dealer and its affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the Settlement Prices, each in a manner that may be adverse to Company.

(ii) Tax Documentation. For purposes of Section 4(a)(i) and (ii) of the Agreement, (i) Company agrees to deliver to Dealer one duly executed and completed United States Internal Revenue Service Form W-9 (or successor thereto) and (ii) Dealer agrees to deliver to Company one duly executed and completed applicable Internal Revenue Service Form W-9 (or successor thereto), in each case, (A) or before the date of execution of this Confirmation and (B) promptly upon learning that any such tax form previously provided by it has become obsolete or incorrect. Additionally, each party shall, promptly upon request by the other party, provide such other tax forms and documents reasonably requested by the other party.

(iii) Payee Tax Representations. Company is a corporation for U.S. federal income tax purposes and is organized under the laws of the State of Delaware. Company 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). Dealer is a “foreign person” (as that term is used in Section 1.6041-4(a)(4) of the United States Treasury Regulations) for United States federal income tax purposes and each payment received or to be received by it in connection with the Agreement is effectively connected with its conduct of a trade or business within the United States. Each party agrees to give notice of any failure of a representation made by it under this Section 9(x)(iii) to be accurate and true promptly upon learning of such failure.
