	Date:	  	[August 28, 2006]

 This master confirmation (this “Master Confirmation”), dated as of [August 28,
2006], is intended to supplement the terms and provisions of certain Transactions (each, a “Transaction”) entered into from time to time between Goldman, Sachs & Co. (“GS&Co.”) and Entegris, Inc.
(“Counterparty”). This Master Confirmation, taken alone, is neither a commitment by either party to enter into any Transaction nor evidence of a Transaction. The terms of any particular Transaction shall be set forth in (i) a
Supplemental Confirmation in the form of Schedule A hereto (a “Supplemental Confirmation”), which shall reference this Master Confirmation and supplement, form a part of, and be subject to this Master Confirmation and (ii) a
Trade Notification in the form of Schedule B hereto (a “Trade Notification”), which shall reference the relevant Supplemental Confirmation and supplement, form a part of, and be subject to such Supplemental Confirmation. This Master
Confirmation, each Supplemental Confirmation and the related Trade Notification together shall constitute a “Confirmation” as referred to in the Agreement specified below. 
 The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the
International Swaps and Derivatives Association, Inc., are incorporated into this Master Confirmation. This Master Confirmation, each Supplemental Confirmation and the related Trade Notification evidence a complete binding agreement between the
Counterparty and GS&Co. as to subject matter and the terms of each Transaction to which this Master Confirmation, such Supplemental Confirmation and Trade Notification relate and shall supersede all prior or contemporaneous written or oral
communications with respect thereto. 
 This Master Confirmation, each Supplemental Confirmation and each Trade Notification supplement, form
a part of, and are subject to an agreement in the form of the 1992 ISDA Master Agreement (Multicurrency –Cross Border) (the “Agreement”) as if GS&Co. and Counterparty had executed the Agreement on the date of this Master
Confirmation (but without any Schedule except for (i) the election of Loss and Second Method, New York law (without regard to the conflicts of law principles) as the governing law and US Dollars (“USD”) as the Termination
Currency, (ii) the election that subparagraph (ii) of Section 2(c) will not apply to Transactions, (iii) the replacement of the word “third” in the last line of Section 5(a)(i) with the word “first” and
(iv) the election that the “Cross Default” provisions of Section 5(a)(vi) shall apply to Counterparty, with a “Threshold Amount” of USD50 million). 
 All provisions contained or incorporated by reference in the Agreement shall govern this Master Confirmation, each Supplemental Confirmation and each
Trade Notification except as expressly modified herein. 
 If, in relation to any Transaction to which this Master Confirmation, a
Supplemental Confirmation and a Trade Notification relate, there is any inconsistency between the Agreement, this Master Confirmation, any 







 Supplemental Confirmation, any Trade Notification and the Equity Definitions, the following will prevail for purposes of
such Transaction in the order of precedence indicated: (i) such Trade Notification, (ii) such Supplemental Confirmation; (iii) this Master Confirmation; (iv) the Agreement; and (v) the Equity Definitions. 
 1. Each Transaction constitutes a Share Forward Transaction for the purposes of the Equity Definitions. Set forth below are the terms and conditions which, together with
the terms and conditions set forth in the related Supplemental Confirmation and Trade Notification (in respect of the relevant Transaction), shall govern each such Transaction.

thereof) for such Exchange Business Day (without regard to pre-open or after hours trading outside of any regular trading session for such Exchange Business Day), as published by Bloomberg at 4:15 p.m. New York time on such Exchange Business Day, on
Bloomberg page “ENTG.Q <Equity> AQR_SEC” (or any successor thereto). For purposes of calculating the VWAP Price, the Calculation Agent will include only those trades that are reported during the period of time during which
Counterparty could purchase its own shares under Rule 10b-18(b)(2), and pursuant to the conditions of Rule 10b-18(b)(3) and (b)(4) each under the Exchange Act (as defined herein) (such trades, “Rule 10b-18 eligible
transactions”).

preceding such Accelerated Termination Date; provided further, that the Accelerated Termination Date for the first Transaction hereunder shall not be a date prior to the Accelerated Valuation Date designated by GS&Co. with respect to the
Accelerated Share









					
		  		  	Buyback transaction evidenced by the confirmation dated [August 28], 2006 between Counterparty and GS&Co. (Ref. Nr.     ) confirming the terms of accelerated
Share buyback transactions between Counterparty and GS&Co. and the supplemental confirmation dated [August 28], 2006 between Counterparty and GS&Co. which supplements, forms part of, and is subject to, such master
confirmation.
			
		  	First Acceleration Date:	  	For each Transaction, as set forth in the Supplemental Confirmation.

faith and commercially reasonable discretion, which date shall be as set forth in the Supplemental Confirmation and Trade Notification (as the same may be postponed in accordance with the provisions herein).

		  		  	Notwithstanding anything to the contrary in the Equity Definitions, to the extent that any Exchange Business Day in the Hedge Period or the Calculation Period is a Disrupted Day, the Calculation
Agent may in good faith and acting in a commercially reasonable manner postpone the Hedge Completion Date or the Termination Date, as the case may be. In such event, the Calculation Agent must determine whether (i) such Disrupted Day is a Disrupted
Day in full, in which case the VWAP Price for such Disrupted Day shall not be included for purposes of determining the Hedge Period Reference Price or the Forward Price, as the case may be, or (ii) such Disrupted Day is a Disrupted Day only in part,
in which case the VWAP Price for such Disrupted Day shall be determined by the Calculation Agent based on Rule 10b-18 eligible transactions in the Shares on such Disrupted Day effected before the relevant Market Disruption Event occurred and/or
after the relevant Market Disruption Event ended, and the weighting of the VWAP Price for the relevant Exchange Business Days during the Hedge Period or the Calculation Period, as the case may be, shall be adjusted in a commercially reasonable
manner by the Calculation Agent for purposes of determining the Hedge Period Reference Price or the Forward Price, as the case may be, with such adjustments based on, among other factors, the duration of any Market Disruption Event and the volume,
historical trading patterns and price of the Shares.
			
		  		  	If a Disrupted Day occurs during the Hedge Period or the Calculation Period, as the case may be, and each of the 9 immediately following Scheduled Trading Days is a Disrupted Day, then the
Calculation Agent, in its good faith and commercially reasonable discretion, may either (i) determine the VWAP Price for such ninth Scheduled Trading Day using its good faith estimate of the value









					
		  		  	of the Shares on such ninth Scheduled Trading Day based on the volume, historical trading patterns and price of the Shares and such other factors as it deems appropriate or (ii) further extend
the Hedge Period or the Calculation Period, as the case may be, as it deems necessary to determine the VWAP Price.

 2. Calculation Agent. GS&Co. 
 3. Additional Mutual Representations, Warranties and Covenants. In addition to the representations and warranties in the Agreement, each party represents, warrants and covenants to the other party that:

 (a) Eligible Contract Participant. It is an “eligible contract participant”, as defined in the U.S. Commodity Exchange Act
(as amended), and is entering into each Transaction hereunder as principal and not for the benefit of any third party. 
 (b) Accredited
Investor. Each party acknowledges that the offer and sale of each 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(2)
thereof and the provisions of Regulation D thereunder (“Regulation D”). Accordingly, each party represents and warrants to the other that (i) it has the financial ability to bear the economic risk of its investment in each
Transaction and is able to bear a total loss of its investment, (ii) it is an “accredited investor” as that term is defined under Regulation D, (iii) it will purchase each Transaction for investment and not with a view to the
distribution or resale thereof in a manner that would violate the Securities Act, and (iv) the disposition of each Transaction is restricted under this Master Confirmation, the Securities Act and state securities laws. 
 (c) Material Nonpublic Information. For the avoidance of doubt, GS&Co. has implemented reasonable policies and procedures, taking into
consideration the nature of its business, to ensure that individuals making investment decisions would not violate laws prohibiting trading on the basis of material nonpublic information. Such individuals shall not be in possession of material
nonpublic information during all relevant times beginning the date hereof through and including the Hedge Completion Date. 
 3A. Additional
Representations, Warranties and Covenants of GS&Co. During the period commencing on the first day of the Hedge Period and ending on the 20th Exchange Business Day immediately following the end of the Calculation Period, or such earlier day as elected by GS&Co. and communicated to Counterparty on such day (the “Relevant
Period”), GS&Co. will use good faith efforts to effect purchases of the Relevant Shares in accordance with Rule 10b-18(b)(2), (3) and (4), and effect calculations in respect thereof, as if those sections applied to GS&Co.,
taking into account any applicable Securities and Exchange Commission no-action letters as appropriate and subject to any delays between the execution and reporting of a trade of the Shares on the Exchange and other circumstances beyond its control.
“Relevant Shares” means, for any Transaction, the excess of the Minimum Shares over the Initial Shares for such Transaction. 
 4.
Additional Representations, Warranties and Covenants of Counterparty. In addition to the representations, warranties and covenants in the Agreement and those contained herein, as of (i) the date hereof, (ii) the Trade Date and
(iii) to the extent indicated below, each day during the Hedge Period and Calculation Period, Counterparty represents, warrants and covenants to GS&Co. that: 
 (a) the purchase or writing of each Transaction and the transactions contemplated hereby will not violate Rule 13e-1 or Rule 13e-4 under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”); 
 (b) it is not entering into any Transaction (i) on the basis of, and is not aware of, any material non-public
information with respect to the Shares (ii) in anticipation of, in connection with, or to facilitate, a distribution of its securities, a self tender offer or a third-party tender offer or (iii) 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); 







 (c) each Transaction is being entered into pursuant to a publicly disclosed Share buy-back program and
its Board of Directors has approved the use of derivatives to effect the Share buy-back program; 
 (d) Counterparty acknowledges that,
notwithstanding the generality of Section 13.1 of the Equity Definitions, it acknowledges that GS&Co. is not making any representations or warranties with respect to the treatment of any Transaction under FASB Statements 128, 133 as
amended, or 149, 150, EITF 00-19 (or any successor issue statements) or under Financial Accounting Standards Board’s Liabilities & Equity Project; 
 (e) Counterparty is in compliance with its reporting obligations under the Exchange Act and its most recent Annual Report on Form 10-K, together with all reports subsequently filed by it pursuant to the Exchange Act,
taken together and as amended and supplemented to the date of this representation, do not, as of their respective filing dates, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, it being understood that Counterparty has no obligation hereunder or under the Agreement to make cash payments to GS&Co. in
the event Counterparty fails to make timely filings with the Securities and Exchange Commission during the term of any Transaction; 
 (f)
Counterparty shall report each Transaction as required under Regulation S-K and/or Regulation S-B under the Exchange Act, as applicable; 
 (g) Counterparty is not, and will not be, engaged in a “distribution” of Shares or securities that are convertible into, or exchangeable or exercisable for Shares for purposes of Regulation M promulgated under the Exchange Act
(“Regulation M”) at any time during the Hedge Period or the Relevant Period, or the one Exchange Business Day immediately following the Relevant Period unless Counterparty has provided written notice to GS&Co. of such
distribution (a “Regulation M Distribution Notice”) not later than the Scheduled Trading Day immediately preceding the first day of the relevant “restricted period” (as defined in Regulation M); Counterparty acknowledges
that any such notice may cause the Hedge Period or the Calculation Period to be extended or suspended pursuant to Section 5 below; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth
in Section 6 below; 
 (h) Counterparty acknowledges that each Transaction is a derivatives transaction in which it has granted
GS&Co. an option. GS&Co. may purchase shares for its own account at an average price that may be greater than, or less than, the price paid by Counterparty under the terms of the related Transaction; 
 (i) as of the Trade Date, the Prepayment Date, the Initial Share Delivery Date, the Minimum Share Delivery Date and the Settlement Date, (i) the
assets of Counterparty at their fair valuation exceed the liabilities of Counterparty, including contingent liabilities, (ii) the capital of Counterparty is adequate to conduct the business of Counterparty and (iii) Counterparty has the
ability to pay its debts and obligations as such debts mature and does not intend to, or does not believe that it will, incur debt beyond its ability to pay as such debts mature; 
 (j) Counterparty is not and, after giving effect to the Transaction, will not be, required to register as an “investment company” as such term
is defined in the Investment Company Act of 1940, as amended; and 
 (k) it has not, and during any Relevant Period will not, enter into
agreements similar to the Transactions described herein where any initial hedge period (however defined) or the calculation period (however defined) in such other transaction will overlap at any time (including as a result of extensions in such
initial hedge period or calculation period as provided in the relevant agreements) with any Hedge Period or Relevant Period under this Master Confirmation. In the event that the initial hedge period or calculation period in any other similar
transaction overlaps with any Hedge Period or Relevant Period under this Master Confirmation as a result of an extension of the Termination Date pursuant to Section 5 herein, Counterparty shall promptly amend such transaction to avoid any such
overlap. 
 5. Suspension of Hedge Period or Calculation Period. 
 (a) If Counterparty concludes that it will be engaged in a distribution of the Shares for purposes of Regulation M, Counterparty agrees that it will, on a day no later than the Scheduled Trading Day immediately








 preceding the start of the relevant restricted period, provide GS&Co. with a Regulation M Distribution Notice. Upon
the effectiveness of such Regulation M Distribution Notice, GS&Co. shall halt any purchase of Shares in connection with hedging any Transaction during the relevant restricted period. If on any Scheduled Trading Day Counterparty delivers the
Regulation M Distribution Notice in writing (and confirms by telephone) by 8:30 a.m. New York Time (the “Notification Time”) then such notice shall be effective as of such Notification Time. In the event that Counterparty delivers
such Regulation M Distribution Notice in writing and/or confirms by telephone after the Notification Time, then such notice shall be effective as of 8:30 a.m. New York Time on the following Scheduled Trading Day or as otherwise required by law or
agreed between Counterparty and GS&Co. The Calculation Period or the Hedge Period, as the case may be, shall be suspended and the Termination Date or the Hedge Completion Date or both, as the case may be, shall postponed for each Scheduled
Trading Day in such restricted period and GS&Co. shall cease effecting purchases of shares in connection with this Transaction; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in
Section 6 below, including, without limitation, the requirement that such notice be made at a time at which none of Counterparty or any officer, director, manager or similar person of Counterparty is aware of any material non-public information
regarding Counterparty or the Shares. 
 (b) In the event that GS&Co. concludes, in its good faith discretion, based on advice of outside
legal counsel, that it is appropriate with respect to any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily
adopted by GS&Co.), for it to refrain from purchasing Shares on any Scheduled Trading Day during the Hedge Period or the Calculation Period, GS&Co. may by written notice to Counterparty elect to suspend the Hedge Period or the Calculation
Period, or both, as the case may be, for such number of Scheduled Trading Days as is specified in the notice; provided that GS&Co. may exercise this right to suspend only in relation to events or circumstances that are unknown to it or any of
its affiliates at the Trade Date of any Transaction, occur within the normal course of its or any of its affiliates’ businesses, and are not the result of deliberate actions of it or any of its affiliates with the intent to avoid its
obligations under the terms of any Transaction. The notice shall not specify, and GS&Co. shall not otherwise communicate to Counterparty, the reason for GS&Co.’s election to suspend the Hedge Period or the Calculation Period, or both,
as the case may be. The Hedge Period or the Calculation Period, or both, as the case may be, shall be suspended and the Termination Date shall be extended for each Scheduled Trading Day occurring during any such suspension. 
 (c) In the event that the Calculation Period or the Hedge Period, as the case may be, is suspended pursuant to Section 5(a) or 5(b) above during the
regular trading session on the Exchange, such suspension shall be deemed to be an additional Market Disruption Event, and the second paragraph under “Market Disruption Event” shall apply to any Disrupted Day occurring during the
Calculation Period or the Hedge Period, as the case may be, solely as a result of such additional Market Disruption Event. 
 (d) In the
event that the Calculation Period is extended pursuant to any provision hereof (including, without limitation, pursuant to Section 9(d) below), the Calculation Agent, in its good faith and commercially reasonable discretion, shall adjust any
relevant terms of the related Transaction if necessary to preserve as nearly as practicable the economic terms of such Transaction prior to such extension; provided that Counterparty shall not be required to make any additional cash payments
or deliver any Shares in connection with any such adjustments. 
 6. 10b5-1 Plan. Counterparty represents, warrants and covenants to GS&Co. that
for each Transaction: 
 (a) Counterparty is entering into this Master Confirmation and each Transaction hereunder in good faith and not as
part of a plan or scheme to evade the prohibitions of Rule 10b5-1 under the Exchange Act (“Rule 10b5-1”). It is the intent of the parties that each Transaction entered into under this Master Confirmation comply with the requirements
of Rule 10b5-1(c)(1)(i)(A) and (B) and each Transaction entered into under this Master Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c). 
 (b) Counterparty will not seek to control or influence GS&Co. to make “purchases or sales” (within the meaning of Rule
10b5-1(c)(1)(i)(B)(3)) under any Transaction entered into under this Master Confirmation, including, without limitation, GS&Co.’s decision to enter into any hedging transactions. Counterparty represents and warrants that it has consulted
with its own advisors as to the legal aspects of its adoption and implementation of this Master Confirmation, each Supplemental Confirmation and each Trade Notification under Rule 10b5-1. 







 (c) Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of this
Master Confirmation, the relevant Supplement Confirmation or Trade Notification must be effected in accordance with the requirements for the amendment or termination of a “plan” as defined in Rule 10b5-1(c). Without limiting the
generality of the foregoing, any such amendment, modification, waiver or termination shall be made in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5, and no such amendment, modification, waiver or termination
shall be made at any time at which Counterparty or any officer, director, manager or similar person of Counterparty is aware of any material non-public information regarding Counterparty or the Shares. 
 7. Counterparty Purchases. 
 Counterparty (or any
“affiliated purchaser” as defined in Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall not, without the prior written consent of GS&Co., directly or indirectly purchase any Shares, listed contracts on the
Shares or securities that are convertible into, or exchangeable or exercisable for Shares (including, without limitation, any Rule 10b-18 purchases of blocks (as defined in Rule 10b-18)) during any Hedge Period or Calculation Period (as extended
pursuant to the provisions hereof). During this time, any such purchases by Counterparty shall be made through GS&Co., or if not through GS&Co., with the prior written consent of GS&Co., and in compliance with Rule 10b-18 or
otherwise in a manner that Counterparty and GS&Co. believe is in compliance with applicable requirements. 
 8. Additional Termination Event. The
declaration of any Extraordinary Dividend by the Issuer during the Calculation Period will constitute an Additional Termination Event, with Counterparty as the sole Affected Party and all Transactions hereunder as the Affected Transactions.

 9. Special Provisions for Merger Transactions. Notwithstanding anything to the contrary herein or in the Equity Definitions, 
 (a) Counterparty shall, prior to the opening of trading in the Shares on any day during any Hedge Period or Calculation Period on which Counterparty
makes, or expects to be made, any public announcement (as defined in Rule 165(f) under the Securities Act of 1933, as amended) of any Merger Transaction, notify GS&Co. of such public announcement; 
 (b) promptly notify GS&Co. following any such announcement that such announcement has been made; and 
 (c) promptly provide GS&Co. 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 GS&Co. 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 GS&Co. that such information is true and correct. In addition, Counterparty shall
promptly notify GS&Co. of the earlier to occur of the completion of such transaction and the completion of the vote by target shareholders. Counterparty acknowledges that any such notice may cause the terms of any Transaction to be adjusted or
such Transaction to be terminated; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 6; and 
 (d) GS&Co. in its sole discretion may (i) make adjustments to the terms of any Transaction, including, without limitation, the Termination Date, the Forward Price Adjustment Amount and the Maximum Shares to
account for the number of Shares that could be purchased on each day during the Hedge Period or the Calculation Period in compliance with Rule 10b-18 following such public announcement, provided that Counterparty shall not be required to make
any additional cash payments or deliver any Shares in connection with any such adjustments or (ii) treat the occurrence of such public announcement as an Additional Termination Event with Counterparty as the sole Affected Party. 







 “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. 
 10. Acknowledgments. The parties hereto intend for: 

(a) Each Transaction to be a “securities contract” as defined in Section 741(7) of the U.S. Bankruptcy Code (Title 11 of the United
States Code) (the “Bankruptcy Code”), a “swap agreement” as defined in Section 101(53B) of the Bankruptcy Code, or a “forward contract” as defined in Section 101(25) of the Bankruptcy Code, and the
parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 362(b)(27), 555, 556, 560 and 561 of the Bankruptcy Code; 
 (b) The Agreement to be a “master netting agreement” as defined in Section 101(38A) of the Bankruptcy Code; 
 (c) A party’s right to liquidate or terminate any Transaction, net out or offset termination values or payment amounts, and to exercise any other
remedies upon the occurrence of any Event of Default or Termination Event under the Agreement with respect to the other party or any Extraordinary Event that results in the termination or cancellation of any Transaction to constitute a
“contractual right” (as defined in the Bankruptcy Code); 
 (d) Any cash, securities or other property transferred as performance
assurance, credit support or collateral with respect to each Transaction to constitute “margin payments” (as defined in the Bankruptcy Code); and 
 (e) All payments for, under or in connection with each Transaction, all payments for the Shares and the transfer of such Shares to constitute “settlement payments” and “transfers” (as defined in
the Bankruptcy Code). 
 11. Credit Support Documents. The parties hereto acknowledge that no Transaction hereunder is secured by any
collateral that would otherwise secure the obligations of Counterparty herein or pursuant to the Agreement. 
 12. Limitation on
Set-off. (a) Notwithstanding anything to the contrary in the Agreement or the Equity Definitions, the calculation of any Settlement Amounts and Unpaid Amounts shall be calculated separately for (A) all Terminated Transactions in the
Shares of the Issuer that qualify as equity under applicable accounting rules (collectively, the “Equity Shares”) as determined by the Calculation Agent and (B) all other Terminated Transactions under the Agreement including,
without limitation, Transactions in Shares other than those of the Issuer (collectively, the “Other Shares”) and the netting and set-off provisions of the Agreement shall only operate to provide netting and set-off (i) among
Terminated Transactions in the Equity Shares and (ii) among Terminated Transactions in the Other Shares. In no event shall the netting and set-off provisions of the Agreement operate to permit netting and set-off between Terminated Transactions
in the Equity Shares and Terminated Transactions in the Other Shares. 
 The parties agree to amend Section 6 of the
Agreement by adding a new Section 6(f) thereto as follows: 
 “(f) Upon the occurrence of an Event of Default or Termination Event
with respect to a party who is the Defaulting Party or the Affected Party or upon the occurrence of an Extraordinary Event that results in the termination or cancellation of any Transaction (such Defaulting Party, Affected Party or, in the case of
such an Extraordinary Event, either party, “X”), the other party (“Y”) will have the right (but not be obliged) without prior notice to X or any other person to set-off or apply any obligation of X owed to Y (or any
Affiliate of Y) (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation) against any obligation of Y (or any Affiliate of Y) owed to X
(whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation). Y will give notice to the other party of any set-off effected under this
Section 6(f). 
 Amounts (or the relevant portion of such amounts) subject to set-off may be converted by Y into the Termination Currency
at the rate of exchange at which such party would be able, acting in a reasonable manner and in good faith, to purchase the relevant amount of such currency. If any 







 obligation is unascertained, Y may in good faith estimate that obligation and set-off in respect of the
estimate, subject to the relevant party accounting to the other when the obligation is ascertained. Nothing in this Section 6(f) shall be effective to create a charge or other security interest. This Section 6(f) shall be without prejudice
and in addition to any right of set-off, combination of accounts, lien or other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).” 
 (b) Notwithstanding anything to the contrary in the foregoing, GS&Co. agrees not to set off or net amounts due from Counterparty with respect to any
Transaction against amounts due from GS&Co. to Counterparty under obligations other than Equity Contracts. “Equity Contract” means any transaction relating to Shares between the parties (or any of their affiliates) that
qualifies as ‘equity’ under applicable accounting rules. 
 13. Early Termination. In the event that an Early Termination
Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to any Transaction (except as a result of a Merger Event in which the consideration or proceeds to be paid to holders of Shares consists
solely of cash), if GS&Co. would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement (calculated as if the Transactions being terminated on such Early Termination Date were the sole Transactions under the Agreement)
(any such amount, a “GS&Co. Amount”), then, in lieu of any payment of such GS&Co. Amount, Counterparty may, no later than the Early Termination Date or the date on which such Transaction is terminated, elect for GS&Co.
to deliver to Counterparty a number of Shares (or, in the case of a Merger Event, a number of units, each comprising the number or amount of the securities or property that a hypothetical holder of one Share would receive in such Merger Event (each
such unit, an “Alternative Delivery Unit” and, the securities or property comprising such unit, “Alternative Delivery Property”)) with a value equal to the GS&Co. Amount, as determined by the Calculation Agent
(and the parties agree that, in making such determination of value, the Calculation Agent may take into account a number of factors, including the market price of the Shares or Alternative Delivery Property on the date of early termination and the
prices at which GS&Co. purchases Shares or Alternative Delivery Property to fulfill its delivery obligations under this Section 13); provided that in determining the composition of any Alternative Delivery Unit, if the relevant
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. 
 14. Payment Date upon Early Termination. Notwithstanding anything to the contrary in Section 6(d)(ii) of the Agreement, all amounts calculated as being due in respect of an Early Termination Date under
Section 6(e) of the Agreement will be payable on the day that notice of the amount payable is effective; provided that if Counterparty elects to receive Shares or Alternative Delivery Property in accordance with Section 13, such
Shares or Alternative Delivery Property shall be delivered on a date selected by GS&Co as promptly as practicable (taking into consideration GS&Co.’s obligations hereunder, including without limitation, its obligations under the second
proviso to Section 13 above). 
 15. Special Provisions for Counterparty Payments. The parties hereby agree that, notwithstanding
anything to the contrary herein or in the Agreement, in the event that an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to any Transaction and, as a result,
Counterparty owes to GS&Co. an amount calculated under Section 6(e) of the Agreement (calculated as if the Transactions being terminated on such Early Termination Date were the sole Transactions under the Agreement), such amount shall be
deemed to be zero. It is understood and agreed that once Counterparty has paid the Prepayment Amount for any Transaction, it has no further obligations to deliver cash or securities upon the settlement of such Transaction. 
 16. Claim in Bankruptcy. GS&Co. agrees that in the event of the bankruptcy of Counterparty, GS&Co. shall not have rights or assert a claim
that is senior in priority to the rights and claims available to the shareholders of the common stock of Counterparty. 
 17. Governing
Law. The Agreement, this Master Confirmation, each Supplemental Confirmation, each Trade Notification and all matters arising in connection with the Agreement, this Master Confirmation, each Supplemental Confirmation and each Trade Notification
shall be governed by, and construed and enforced in accordance with, the laws of the State of New York (without reference to its choice of laws doctrine). 







 18. Offices. 
 (a) The Office of GS&Co. for each Transaction is: One New York Plaza, New York, New York 10004. 
 (b) The Office of
Counterparty for each Transaction is: 3500 Lyman Boulevard, Chaska, Minnesota 55318. 
 19. Arbitration. The Agreement, this Master Confirmation,
each Supplemental Confirmation and each Trade Notification are subject to the following arbitration provisions: 
 (a) All parties to
this Confirmation are giving up the right to sue each other in court, including the right to a trial by jury, except as provided by the rules of the arbitration forum in which a claim is filed. 
 (b) Arbitration awards are generally final and binding; a party’s ability to have a court reverse or modify an arbitration award is very limited.

 (c) The ability of the parties to obtain documents, witness statements and other discovery is generally more limited in arbitration
than in court proceedings. 
 (d) The arbitrators do not have to explain the reason(s) for their award. 
 (e) The panel of arbitrators will typically include a minority of arbitrators who were or are affiliated with the securities industry, unless
Counterparty is a member of the organization sponsoring the arbitration facility, in which case all arbitrators may be affiliated with the securities industry. 
 (f) The rules of some arbitration forums may impose time limits for bringing a claim in arbitration. In some cases, a claim that is ineligible for arbitration may be brought in court. 
 (g) The rules of the arbitration forum in which the claim is filed, and any amendments thereto, shall be incorporated into this Confirmation.

 Counterparty agrees that any and all controversies that may arise between Counterparty and GS&Co., including, but not limited
to, those arising out of or relating to the Agreement or any Transaction hereunder, shall be determined by arbitration conducted before The New York Stock Exchange, Inc. (“NYSE”) or NASD Dispute Resolution (“NASD-DR”), or, if the
NYSE and NASD-DR decline to hear the matter, before the American Arbitration Association, in accordance with their arbitration rules then in force. The award of the arbitrator shall be final, and judgment upon the award rendered may be entered in
any court, state or federal, having jurisdiction. 
 No person shall bring a putative or certified class action to arbitration, nor
seek to enforce any pre-dispute arbitration agreement against any person who has initiated in court a putative class action or who is a member of a putative class who has not opted out of the class with respect to any claims encompassed by the
putative class action until: (i) the class certification is denied; (ii) the class is decertified; or (iii) Counterparty is excluded from the class by the court. 
 Such forbearance to enforce an agreement to arbitrate shall not constitute a waiver of any rights under this Confirmation except to the extent stated
herein.” 







 20. Counterparts. This Master Confirmation may be executed in any number of counterparts, all of which shall
constitute one and the same instrument, and any party hereto may execute this Master Confirmation by signing and delivering one or more counterparts. 
 21.
Counterparty hereby agrees (a) to check this Master Confirmation carefully and immediately upon receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form
provided by GS&Co.) correctly sets forth the terms of the agreement between GS&Co. and Counterparty with respect to any particular Transaction to which this Master Confirmation relates, by manually signing this Master Confirmation or this
page hereof as evidence of agreement to such terms and providing the other information requested herein and immediately returning an executed copy to Equity Derivatives Documentation Department, Facsimile No. 212-428-1980/83.
