(“Company”) to Credit Suisse LLC (“Dealer”), represented by Credit Suisse Securities (USA) LLC (“Agent”) as its agent, as of the Trade Date specified below (the “Transaction”). This letter agreement constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below. Each party further agrees that this Confirmation together with the Agreement evidence a complete binding agreement between Company and Dealer as to the subject matter and terms of the Transaction to which this Confirmation relates, and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

1.This Confirmation evidences a complete and binding agreement between Dealer and Company as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall supplement, form a part of, and be subject to an agreement 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. In the event of any inconsistency between provisions of the Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this Confirmation relates. The parties hereby agree that no Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement.

2.    The Transaction is a Warrant Transaction, which shall be considered a Share Option Transaction for purposes of the Equity Definitions. The terms of the particular Transaction to which this Confirmation relates are as follows:

Equity Definitions, each reference to a Warrant herein shall be deemed to be a reference to a Call Option.

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:

adjustments provided herein, is (i) less than 95.9 million (in the case of the first such notice) or (ii) thereafter more than 10.8 million less than the number of Shares included in the immediately preceding Repurchase Notice. Company agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and reasonable expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person actually may become subject to, as a result of Company’s failure to provide Dealer with a Repurchase Notice when 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, 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.

recognized dealer in transactions of the same type as the Transaction provided that, (i) no Event of Default, Potential Event of Default or Termination Event will occur as a result of such transfer and assignment and (ii) after such transfer and/or assignment, Company shall not be required to pay the transferee or assignee of such rights or obligations on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than the amount, if any, that Company would have been required to pay Dealer in the absence of such transfer and/or assignment, except to the extent such greater amount results from a Change in Tax Law occurring after the date of such transfer and/or assignment. Dealer shall promptly notify Company of any transfer or assignment made hereunder. If at any time at which (A) the Section 16 Percentage exceeds 8.5%, (B) the Warrant Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants 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 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.

converted into cash, securities or other property or assets or (III) any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of Company and its subsidiaries, taken as a whole, to any person other than one of Company’s wholly owned subsidiaries. Notwithstanding the foregoing, any transaction or transactions set forth in clause (A) above or this clause (B) shall not constitute an Additional Termination Event if at least 90% of the consideration received or to be received by holders of the Shares, excluding cash payments for fractional Shares and cash payments made in respect of dissenters' appraisal rights, in connection with such transaction or transactions consists of shares of common stock that are listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions.

bankruptcy or liquidation of either Company 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.

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.

Company shall immediately notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares or Restricted Shares, as the case may be, to be delivered) and promptly deliver such Shares or Restricted Shares, as the case may be, thereafter.
