Requested if Dealer is not the highest rated entity in group, typically from the Parent.

Notwithstanding Section 3.4 of the Equity Definitions, on each Conversion Date in respect of which a Notice of Conversion that is effective as to Counterparty has been delivered by the relevant converting Holder (as such term is defined in the Indenture), a number of Options equal to the Number of Relevant Options shall be deemed to be automatically exercised; provided that such Options shall be exercised or deemed exercised only if Counterparty or the Trustee (or other agent authorized by Counterparty and previously identified to Dealer by Counterparty in writing) on behalf of Counterparty has provided a Notice of Exercise to Dealer in accordance with “Notice of Exercise” below. If the Trustee (or any other such agent) on behalf of the Counterparty provides any Notice of Exercise to Dealer, Dealer shall be entitled to rely on the accuracy of such Notice of Exercise without any independent investigation, and the contents of such notice shall be binding on Counterparty.

Notwithstanding the foregoing, in no event shall the number of Options that are exercised or deemed exercised hereunder exceed the Number of Options.

In respect of any Option:

(i) if Counterparty has elected to settle its conversion obligations in respect of the Relevant Convertible Note (A) entirely in Shares pursuant to Section 10.02(b) of the Indenture (together with cash in lieu of fractional Shares) (such settlement method, “Settlement in Shares”); (B) in a combination of cash and Shares

pursuant to Section 10.02(b) of the Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “Low Cash Combination Settlement”); or (C) in a combination of cash and Shares pursuant to Section 10.02(b) of the Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for such Option shall be Net Share Settlement;

(ii) if Counterparty has elected to settle its conversion obligations in respect of the Relevant Convertible Note in a combination of cash and Shares pursuant to Section 10.02(b) of the Indenture with a Specified Cash Amount greater than USD 1,000, then the Relevant Settlement Method for such Option shall be Combination Settlement; and

(iii) if Counterparty has elected to settle its conversion obligations in respect of the Relevant Convertible Note entirely in cash pursuant to Section 10.02(b) of the Indenture (such settlement method, “Settlement in Cash”), then the Relevant Settlement Method for such Option shall be Cash Settlement.

For any Relevant Settlement Method other than Net Share Settlement with a Specified Cash Amount equal to USD 1,000, the Notice of Exercise or Notice of Final Settlement Method for such Option, as applicable, shall be deemed to contain:

(i) a representation that, on the date of such Notice of Exercise or Notice of Final Settlement Method, as applicable, none of Counterparty and its officers and directors is aware or in possession of any material non-public information with respect to Counterparty or the Shares;

(ii) a representation that Counterparty is electing the settlement method for the Relevant Convertible Note and such Relevant Settlement Method in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”);

(iii) a representation that Counterparty has not entered into or altered any hedging transaction relating to the Shares corresponding to or offsetting the Transaction;

(iv) a representation that Counterparty is not electing the settlement method for the Relevant Convertible Note and such Relevant Settlement Method to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act; and

(v) an acknowledgment by Counterparty that (A) any transaction by Dealer following Counterparty’s election of the settlement method for the Relevant Convertible Note and such Relevant Settlement Method shall be made at Dealer’s sole discretion and for Dealer’s own account and (B) Counterparty does not have, and shall not attempt to exercise, any influence over how, when, whether or at what price to effect such transactions, including, without limitation, the price paid or received per Share pursuant to such transactions, or whether such transactions are made on any securities exchange or privately.

If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of the obligations set forth in Sections 8.1 and 9.1 of the Equity Definitions, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, an aggregate number of Shares and, if any, cash in lieu of fractional shares as provided below (the “Net Share Settlement Amount”) equal to the sum for each Trading Day during the applicable Conversion Period for each such Option of a number of Shares of each such Trading Day equal to (i) the Daily Option Value for such Trading Day, divided by (ii) the VWAP Price on such Trading Day, divided by (iii) the number of Trading Days in the applicable Conversion Period; provided that in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for the Option.

Dealer will deliver cash in lieu of any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the VWAP Price for the last Trading Day of the applicable Conversion Period.

If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of the obligations set forth in Sections 8.1 and 9.1 of the Equity Definitions, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option:

(i) cash (the “Combination Settlement Cash Amount”) equal to the sum for each Trading Day during the applicable Conversion Period for such Option of an amount for each such Trading Day (the “Daily Combination Settlement Cash Amount”) equal to (A) the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Trading Days in the applicable Conversion Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Trading Day, the Daily Combination Settlement Cash Amount for such Trading Day shall be deemed to be zero; and

(ii) an aggregate number of Shares (the “Combination Settlement Share Amount”) equal to the sum for each Trading Day during the applicable Conversion Period for such Option of a number of Shares for each such Trading Day (the “Daily Combination Settlement Share Amount”) equal to (A) the Daily Option Value on such Trading Day minus the Daily Combination Settlement Cash Amount for such Trading Day (the remainder, the “Daily Share Value”), divided by (B) the VWAP Price on such Trading Day, divided by (C) the number of Trading Days in the applicable Conversion Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Trading Day, the Daily Combination Settlement Share Amount for such Trading Day shall be deemed to be zero.

provided, however, if the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the sum for each Trading Day during the applicable Conversion Period for such Option of the quotient of the Daily Share Value on such Trading Day divided by the number of Trading Days in such Conversion Period exceeded the Applicable Limit for such Option, the Combination Settlement Share Amount for such Option shall be reduced by a number of Shares equal to the amount of such excess divided by the Applicable Limit Price on the Settlement Date for the Option, and if the amount of such excess is greater than such Combination Settlement Share Amount, the Combination Settlement Cash Amount shall be reduced by such excess.

Dealer will deliver cash in lieu of any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the VWAP Price for the last Trading Day of the applicable Conversion Period.

Section 6.3(a) of the Equity Definitions is hereby replaced in its entirety by the following:

“‘Market Disruption Event’ means, in respect of a Share, (i) a failure by the primary U.S. national or regional securities exchange or market on which the Shares are listed or admitted for trading to open for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00 p.m. New York City time on any Scheduled Trading Day for the Shares for more than one half-hour period in the aggregate during regular trading hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Shares or in any options, contracts or futures contracts relating to the Shares.”

For any Option and regardless of the Settlement Method applicable to such Option:

(i) if the related Conversion Date occurs prior to the Free Convertibility Date, the 40 consecutive Trading Days commencing on, and including, the second Trading Day immediately following such Conversion Date; provided that if the Notice of Exercise for such Option specifies that Settlement in Shares or Low Cash Combination Settlement applies to the Relevant Convertible Note, the Conversion Period shall be the 80 consecutive Trading Day period commencing on, and including, the second Trading Day immediately following the receipt of such Notice of Exercise;

(ii) if the related Conversion Date occurs on or following the Free Convertibility Date, the 40 consecutive Trading Days commencing on, and including, the 41st Scheduled Trading Day immediately prior to the “Maturity Date” (as defined in the Indenture); provided that if the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option specifies that Settlement in Shares or Low Cash Combination Settlement applies to the Relevant Convertible Note, the Conversion Period shall be the 80 consecutive Trading Days commencing on, and including, the 81st Scheduled Trading Day immediately prior to the “Maturity Date”.

Applicable; provided that

(i) Section 12.9(a)(v) of the Equity Definitions is hereby modified by inserting the following three sentences at the end of such Section:

“Such inability described in phrases (A) or (B) above shall not constitute a “Hedging Disruption” unless (x) such inability does not result from factors particular to Hedging Party (such as Hedging Party’s creditworthiness or financial position, or particular actions or transactions undertaken by the Hedging Party unrelated to the hedging of the Transaction) and (y) such inability will result in continued performance by the Hedging Party under the Transaction being commercially unreasonable or commercially impracticable. For the avoidance of doubt, the term “equity price risk” shall be deemed to include, but shall not be limited to, stock price and volatility risk. And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or (B) above must be available on commercially reasonable pricing terms.”

(ii) Section 12.9(b)(iii) of the Equity Definitions is hereby amended by inserting in the third line thereof, after the words “to terminate the Transaction”, the words “or a portion of the Transaction affected by such Hedging Disruption”.

Commodity Exchange Act. It is an “eligible contract participant” within the meaning of Section 1a(12) of the U.S. Commodity Exchange Act, as amended (the “CEA”).

each of Counterparty’s filings under the Securities Act, the Exchange Act, or other applicable securities laws that are required to be filed have been filed and that, as of the respective dates thereof and as of the date of this representation, such filings when considered as a whole (with the more recent such filings deemed to amend inconsistent statements contained in any earlier such filings) do not contain any misstatement of a material fact or any omission of a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading;

Counterparty understands, agrees and acknowledges that no obligations of Dealer to it hereunder shall be entitled to the benefit of deposit insurance and that such obligations shall not be guaranteed by any affiliate of Dealer or any governmental agency;

without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that Dealer is not making any representations or warranties 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, 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;

Counterparty is not entering into the Transaction for the purpose of (i) creating actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or (ii) raising or depressing or otherwise manipulating the price of, or facilitating a distribution of, the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act;

No Pennsylvania state or local law, rule, regulation or regulatory order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) as a result of Dealer or its affiliates owning or holding (however defined) Shares in connection with Dealer’ obligations under the Transaction, except as previously disclosed by Counterparty to Dealer.

Method of Delivery. Whenever delivery of funds or other assets is required hereunder by or to Counterparty, such delivery shall be effected through Agent. In addition, all notices, demands and communications of any kind relating to the Transaction between Dealer and Counterparty may be transmitted exclusively through Agent.

Dividends. If at any time during the period from and including the Premium Payment Date, to but excluding the Expiration Date, (i) an ex-dividend date for a regular quarterly cash dividend occurs with respect to the Shares (an “Ex-Dividend Date”), and that dividend is less than the Regular Dividend on a per Share basis or (ii) if no Ex-Dividend date for a regular quarterly cash dividend occurs with respect to the Shares in any quarterly dividend period of Counterparty, then the Calculation Agent will make a corresponding adjustment to any one or more of the Strike Price, Number of Options, Option Entitlement and/or any other variable relevant to the exercise, settlement or payment for the Transaction to preserve the fair value of the Options to Dealer after taking into account such dividend or lack thereof. “Regular Dividend” shall mean USD 0.35 per Share per quarter. Upon any adjustment to the Dividend Threshold Amount (as defined in the Indenture) for the Convertible Notes pursuant to Section 10.04(d) or Section 10.05 of the Indenture, the Calculation Agent will make a corresponding adjustment to the Regular Dividend for the Transaction.

Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the Options Equity Percentage as determined on such day is (i) equal to or greater than 9% and (ii) greater by 0.5% than the Options Equity Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the Options Equity Percentage as of the Trade Date). The “Options Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the product of the Number of Options in the aggregate and the Option Entitlement [under the Transaction and any other bond hedge transaction between the parties] and (B) the denominator of which is the number of Shares outstanding on such day. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’ hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person in respect of the foregoing, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent

Rule 10b-18.

Except as disclosed to Dealer in writing prior to the date on which the offering of the Convertible Notes was first announced, Counterparty represents and warrants to Dealer that it has not made any purchases of blocks by or for itself or any of its Affiliated Purchasers pursuant to the one block purchase per week exception in Rule 10b-18(b)(4) under the Exchange Act during each of the four calendar weeks preceding such date and the calendar week in which such date occurs (“Rule 10b-18 purchase,” “blocks” and “Affiliated Purchaser” each as defined in Rule 10b-18 under the Exchange Act). Counterparty agrees and acknowledges that it shall not, and shall cause its affiliates and Affiliated Purchasers not to, directly or indirectly (including by means of a derivative instrument) enter into any transaction to purchase any Shares during the period beginning on such date and ending on the day on which Dealer has informed Counterparty in writing that it has completed all purchases of Shares to hedge initially its exposure to the Transaction; provided that the foregoing shall not apply to the Counterparty’s repurchase of shares of common stock concurrently with the offering of Convertible Notes.

On any day during any Conversion Period, neither Counterparty nor any “affiliate” or “affiliated purchaser” (each as defined in Rule 10b-18 of 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, except through Dealer or with Dealer’s prior written consent.

Counterparty agrees that it (A) will not, on any day during any Conversion Period, make, or permit to be made (to the extent within Counterparty’s reasonable control), any public announcement (as defined in Rule 165(f) under the Securities Act) of any Merger Transaction or potential Merger Transaction unless such public announcement is made prior to the opening or after the close of the regular trading session on the Exchange for the Shares; (B) shall promptly (but in any event prior to the next opening of the regular trading session on the Exchange) notify Dealer following any such announcement that such announcement has been made; and (C) shall promptly (but in any event prior to the next opening of the regular trading session on the Exchange) provide Dealer with written notice specifying (i) Counterparty’s average daily Rule 10b-18 Purchases (as defined in Rule 10b-18) during the three full calendar months immediately preceding the announcement date that were not effected through Dealer or its affiliates and (ii) the number of Shares purchased pursuant to the proviso in Rule 10b-18(b)(4) under the Exchange Act for the three full calendar months preceding the announcement date. Such written notice shall be deemed to be a certification by Counterparty to Dealer that such information is true and correct. In addition, Counterparty shall promptly notify Dealer of the earlier to occur of the completion of such transaction and the completion of the vote by target shareholders. “Merger Transaction” means any merger, acquisition or similar transaction involving a recapitalization as contemplated by Rule 10b-18(a)(13)(iv) under the Exchange Act.

Regulation M. Counterparty represents and warrants to Dealer that (x) Counterparty (A) was not on the date on which the offering of the Convertible Notes was first announced, has not since such date, and is not on the date hereof, engaged in a “distribution”, as such term is used in Regulation M under the Exchange Act (“Regulation M”), of any securities of Counterparty, other than the distribution of the Convertible Notes and (B) shall not engage in any “distribution,” as such term is defined in Regulation M, of any securities of Counterparty other than a distribution meeting the requirements of the exceptions set forth in sections 101(b)(10) and 102(b)(7) of Regulation M, until the second Exchange Business Day immediately following the Trade Date, and (y) Counterparty shall notify Dealer in writing of the start of a “restricted period”, as defined in Regulation M, no later than the Scheduled Trading Day immediately before the start of any such restricted period, to the extent Counterparty is engaged in any “distribution,” as such term is defined in Regulation M, of any securities of Counterparty other than a distribution meeting the requirements of the exceptions set forth in sections 101(b)(10) and 102(b)(7) of Regulation M, on any day during any Conversion Period.

Early Unwind. In the event the sale of Convertible Notes is not consummated with the initial purchaser for any reason by the close of business in New York on June 3, 2019 (or such later date as agreed upon by the parties) (June 3, 2019 or such later date as agreed upon 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 under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date; provided that, except to the extent that the Early Unwind Date occurred as a result of a breach of the Purchase Agreement by Dealer or any of its affiliates, Counterparty shall reimburse Dealer for any costs or expenses (including market losses, unless Counterparty agrees to purchase any such Shares at the cost at which Dealer purchased such Shares) relating to the unwinding of its hedging activities in connection with the Transaction (including any loss or cost incurred as a result of its terminating, liquidating, obtaining or reestablishing any hedge or related trading position). The amount of any such reimbursement shall be determined by Dealer in its sole good faith discretion. Dealer shall notify Counterparty of such amount and Counterparty shall pay such amount in immediately available funds on the Early Unwind Date. Dealer and Counterparty represent and acknowledge to the other that, subject to the proviso included in this paragraph, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

Transfer or Assignment.

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

With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to paragraph 5(e) of this Confirmation, its registration obligations pursuant to paragraph 5(p) of this Confirmation, or its obligation to provide a Notice of Merger Consideration pursuant to paragraph 2 of this Confirmation;

Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Code);

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

Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment except to the extent that the greater amount is due to a Change in Tax Law after the date of such transfer or assignment;

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

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

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

Notwithstanding any provision of the Agreement to the contrary, Dealer may, subject to applicable law, freely transfer and assign all of its rights and obligations under the Transaction or the Agreement without the consent of Counterparty, (x) to any of its affiliates and (y) solely to the extent required to

Staggered Settlement. Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares deliverable on such Nominal Settlement Date 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 Conversion Period or delivery times and how it will allocate the Shares it is required to deliver under “Net Share Settlement” above among the Staggered Settlement Dates or delivery times; and (ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date.

[Role of Agent. Each of Dealer and Counterparty acknowledges to and agrees with the other party hereto and to and with the Agent that (i) the Agent is acting as agent for Dealer under the Transaction pursuant to instructions from such party, (ii) the Agent is not a principal or party to the Transaction, and may transfer its rights and obligations with respect to the Transaction, (iii) the 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. Each party hereto acknowledges and agrees that the Agent is an intended third party beneficiary hereunder. 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.]⁵

Regulatory Provisions. The time of dealing for the Transaction will be confirmed by Dealer upon written request by Counterparty. The Agent will furnish to Counterparty upon written request a statement as to the source and amount of any remuneration received or to be received by the Agent in connection with the Transaction.

No Setoff. Obligations under the Transaction shall not be netted, recouped or set off (including pursuant to Section 6 of the Agreement) against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall be netted, recouped or set off (including pursuant to Section 6 of the Agreement) against obligations under the Transaction, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff, netting or recoupment, provided that both parties agree that subparagraph (ii) of Section 2(c) of the Agreement shall apply to the Transaction.
