Re:     Master Confirmation-Uncollared Accelerated Share Repurchase
This master confirmation (this “Master Confirmation”), dated as of October 26, 2015, is intended to set forth certain terms and provisions of certain Transactions (each, a “Transaction”) entered into from time to time between Citibank, N.A. (“Dealer”) and Rambus, Inc., a Delaware corporation (“Counterparty”).  This Master Confirmation, taken alone, is neither a commitment by either party to enter into any Transaction nor evidence of a Transaction.  The additional terms of any particular Transaction shall be set forth in 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.  This Master Confirmation and each Supplemental Confirmation 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 and each Supplemental Confirmation evidence a complete binding agreement between Counterparty and Dealer as to the subject matter and terms of each Transaction to which this Master Confirmation and such Supplemental Confirmation relate and shall supersede all prior or contemporaneous written or oral communications with respect thereto.  
This Master Confirmation and each Supplemental Confirmation supplement, form a part of, and are subject to an agreement in the form of the 2002 ISDA Master Agreement (the “Agreement”) as if Dealer and Counterparty had executed the Agreement on the date of this Master Confirmation, without any Schedule, but with the elections set forth in this Master Confirmation, including: 
(i)    The election of New York law as the governing law (without reference to its choice of law provisions). 
(ii)     The election that subparagraph (ii) of Section 2(c) will not apply to the Transactions. 
(iii)    [Reserved]
(iv)     The election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Dealer, with a “Threshold Amount” of 3% of shareholders’ equity for Dealer (provided that (a) the phrase “, or becoming capable at such time of being declared,” shall be deleted from clause (1) of such Section 5(a)(vi) of the Agreement, (b) “Specified Indebtedness” shall have the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect of deposits received in the ordinary course of Dealer’s banking business and (c) the following sentence shall be added to the end thereof: “Notwithstanding the foregoing, an Event of Default shall not occur under either (1) or (2) above if (a) the event or condition referred to in (1) or the failure to pay referred to in (2) is caused by an error or omission of an administrative or operational nature, (b) funds were available to Dealer to enable it to make the relevant payment when due, and (c) such payment is made within three Local Business Days after notice of such failure is given by Counterparty.”).
(v)    “Affiliate” will have the meaning specified in Section 14 of the Agreement, except that for purposes of Section 3(c) of the Agreement as set forth in clause (iii) above, “Affiliate” means, with respect to any person, any entity controlled, directly or indirectly by such person.  For this purpose, “control” means ownership of a majority of the voting power of the entity or person.
(vi)    For purposes of Section 3(f) of the Agreement, Dealer makes the following representation:

It is a U.S. person, and it is a national banking association organized under the laws of the United States.  
(vii)    For purposes of Section 3(f) of the Agreement, Counterparty makes the following representation:
It is a U.S. person, and it is a corporation organized under the State of Delaware.
(viii)    Each party agrees to deliver a complete and accurate United States Internal Revenue Service Form W-9 to the other party upon execution of this Agreement.
The Transactions shall be the sole Transactions under the Agreement.  If there exists any ISDA Master Agreement between Dealer and Counterparty or any confirmation or other agreement between Dealer and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Dealer and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which Dealer and Counterparty are parties, the Transactions shall not be considered Transactions under, or otherwise governed by, such existing or deemed ISDA Master Agreement, and the occurrence of any Event of Default or Termination Event under the Agreement with respect to either party or any Transaction shall not, by itself, give rise to any right or obligation under any such other agreement or deemed agreement.  Notwithstanding anything to the contrary in any other agreement between the parties or their Affiliates, the Transactions shall not be “Specified Transactions” (or similarly treated) under any other agreement between the parties or their Affiliates.
All provisions contained or incorporated by reference in the Agreement shall govern this Master Confirmation and each Supplemental Confirmation except as expressly modified herein or in the related Supplemental Confirmation.  
If, in relation to any Transaction to which this Master Confirmation and a Supplemental Confirmation relate, there is any inconsistency between the Agreement, this Master Confirmation, such Supplemental Confirmation and the Equity Definitions, the following will prevail for purposes of such Transaction in the order of precedence indicated: (i) such Supplemental Confirmation; (ii) this Master Confirmation; (iii) the Equity Definitions; and (iv) the Agreement.  
		
	1.

excluding (i) trades that do not settle regular way, (ii) opening (regular way) reported trades in the consolidated system on such Exchange Business Day, (iii) trades that occur in the last ten minutes before the scheduled close of trading on the Exchange on such Exchange Business Day and ten minutes before the scheduled close of the primary trading in the market where the trade is effected, and (iv) trades on such Exchange Business Day that do not satisfy the requirements of Rule 10b-18(b)(3) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as published by Bloomberg at 4:15 p.m. New York time (or 15 minutes following the end of any extension of the regular trading session) on such Exchange Business Day, on Bloomberg page “RMBS <Equity> AQR_SEC” (or any successor thereto), or if such price is not so reported on such Exchange Business Day for any reason or is, in the Calculation Agent’s good faith and commercially reasonable determination, erroneous, such VWAP Price shall be as determined in good faith and in a commercially reasonable manner by the Calculation Agent (all such trades other than any trades described in clauses (i) to (iv) above, “Rule 10b-18 Eligible Transactions”); provided that the first trade in the Shares during the regular trading session on the Exchange (even if such trade is reported on such Bloomberg Page) shall be excluded from the VWAP Price for such Exchange Business Date.  
		
	Forward Price:
	For each Transaction, the arithmetic average of the VWAP Prices for all of the Exchange Business Days in the Calculation Period for such Transaction, subject to “Valuation Disruption” below.

		
	Forward Price Adjustment Amount:
	For each Transaction, as set forth in the related Supplemental Confirmation.

	Calculation Period Start Date:
	For each Transaction, as set forth in the related Supplemental Confirmation.  

		
	Termination Date:
	For each Transaction, the Scheduled Termination Date for such Transaction; provided that in no event shall the Scheduled Termination Date be postponed to a date later than the Final Termination Date; provided further that Dealer shall have the right to designate any Exchange Business Day on or after the First Acceleration Date to be the Termination Date for the entire Transaction (the “Accelerated Termination Date”) by delivering notice to Counterparty of any such designation prior to 6:00 p.m. (New York City time) on the second Exchange Business Day immediately following the designated Accelerated Termination Date; provided further that if Dealer expects that the Number of Shares to be Delivered will be a negative number as a result of any Acceleration prior to the Scheduled Termination Date, then Dealer shall use its reasonable efforts to provide, to the extent feasible, the Counterparty notice of any such Acceleration prior to any such proposed Acceleration.

		
	Scheduled Termination Date:
	For each Transaction, as set forth in the related Supplemental Confirmation, subject to postponement as provided in “Valuation Disruption” below; provided that in no event shall the Scheduled Termination Date be postponed to a date later than the Final Termination Date.  

		
	Final Termination Date:
	For each Transaction, as set forth in the related Supplemental Confirmation.

		
	First Acceleration Date:
	For each Transaction, as set forth in the related Supplemental Confirmation.

		
	Valuation Disruption:
	The definition of “Market Disruption Event” in Section 6.3(a) of the Equity Definitions is hereby amended by deleting the words “at any time during the one-hour period that ends at the relevant Valuation Time, Latest Exercise Time, Knock-in Valuation Time or Knock-out Valuation Time, as the case may be” and inserting the words “at any time on any Scheduled Trading Day during the Calculation Period or Settlement Valuation Period” after the word “material,” in the third line thereof.

Section 6.3(d) of the Equity Definitions is hereby amended by deleting the remainder of the provision following the term “Scheduled Closing Time” in the fourth line thereof.  
Notwithstanding anything to the contrary in the Equity Definitions, if a Disrupted Day occurs (i) in the Calculation Period, the Calculation Agent may, in its good faith and commercially reasonable judgment, postpone the Scheduled Termination Date by one Scheduled Trading Day for each Disrupted Day (provided that in no event shall the Scheduled Termination Date be postponed to a date later than the Final Termination Date), or (ii) in the Settlement Valuation Period, the Calculation Agent may extend the Settlement Valuation Period.  The Calculation Agent may also determine that (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 Forward Price or the Settlement 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 taking into account the nature and duration of the relevant Market Disruption Event, and the weighting of the VWAP Price for the relevant Exchange Business Days during the Calculation Period or the Settlement Valuation Period, as the case may be, shall be adjusted in a commercially reasonable manner by the Calculation Agent for purposes of determining the Forward Price or the Settlement 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.  Any Disrupted Day resulting from a Regulatory Disruption shall be deemed to be a Disrupted Day in full.  Any Exchange Business Day on which, as of the date hereof, the Exchange is scheduled to close prior to its normal close of trading shall be deemed not to be an Exchange Business Day; if a closure of the Exchange prior to its normal close of trading on any Exchange Business Day is scheduled following the date hereof, then such Exchange Business Day shall be deemed to be a Disrupted Day in full.  
If a Disrupted Day occurs during the Calculation Period for any Transaction or the Settlement Valuation Period for any Transaction, as the case may be, and each of the nine immediately following Scheduled Trading Days is a Disrupted Day (a “Disruption Event”), then the Calculation Agent, in its good faith and commercially reasonable discretion, may deem such Disruption Event (and each consecutive Disrupted Day thereafter) to be either (x) a Potential Adjustment Event in respect of such Transaction or (y) an Additional Termination Event 

in respect of such Transaction, with Counterparty as the sole Affected Party and such Transaction as the sole Affected Transaction.  
Settlement Terms.
		
	Settlement Procedures:
	For each Transaction:

		
	(i)
	if the Number of Shares to be Delivered for such Transaction is positive, Physical Settlement shall be applicable to such Transaction; provided that the “Representation and Agreement” contained in Section 9.11 of the Equity Definitions shall be modified by excluding any representations therein relating to restrictions obligations, limitations or requirements under applicable securities laws arising as a result of the fact that Buyer is the Issuer of the Shares; or

		
	(ii)
	if the Number of Shares to be Delivered for such Transaction is negative, then Counterparty Settlement Provisions in Annex A hereto shall apply to such Transaction.  

		
	Number of Shares to be Delivered:
	For each Transaction, a number of Shares (rounded down to the nearest whole number) equal to (a)(i) the Prepayment Amount for such Transaction, divided by (ii)(A) the Forward Price for such Transaction minus (B) the Forward Price Adjustment Amount for such Transaction, minus (b) the number of Initial Shares for such Transaction; provided that if the result of the calculation in clause (a)(ii) is equal to or less than the Floor Price for such Transaction, then the Number of Shares to be Delivered for such Transaction shall be determined as if clause (a)(ii) were replaced with “(ii) the Floor Price for such Transaction”.  For the avoidance of doubt, if the Forward Price Adjustment Amount for any Transaction is a negative number, clause (a)(ii) of the immediately preceding sentence shall be equal to (A) the Forward Price for such transaction, plus (B) the absolute value of the Forward Price Adjustment Amount.

		
	Floor Price:
	For each Transaction, as set forth in the related Supplemental Confirmation.

		
	Excess Dividend Amount:
	For the avoidance of doubt, all references to the Excess Dividend Amount shall be deleted from Section 9.2(a)(iii) of the Equity Definitions.

		
	Settlement Date:
	For each Transaction, if the Number of Shares to be Delivered for such Transaction is positive, the date that is one Settlement Cycle immediately following the Termination Date for such Transaction (which as of the date hereof shall be no more than three Clearance System Business Days following the Termination Date for such Transaction).    

		
	Settlement Currency:
	USD 

		
	Initial Share Delivery:
	For each Transaction, Dealer shall deliver a number of Shares equal to the Initial Shares for such Transaction to Counterparty on the Initial Share Delivery Date for such Transaction in accordance with Section 9.4 of the Equity Definitions, with such Initial Share Delivery Date deemed to be a “Settlement Date” for purposes of such Section 9.4.  

		
	Initial Share Delivery Date:
	For each Transaction, as set forth in the related Supplemental Confirmation.  

		
	Initial Shares:
	For each Transaction, as set forth in the related Supplemental Confirmation.  

Share Adjustments.
		
	Potential Adjustment Event:
	In addition to the events described in Section 11.2(e) of the Equity Definitions, it shall constitute an additional Potential Adjustment Event if (x) the Scheduled Termination Date for any Transaction is postponed pursuant to “Valuation Disruption” above (including, for the avoidance of doubt, pursuant to Section 7 hereof) (a “Valuation Disruption Postponement”), (y) a Regulatory Disruption as described in Section 7 occurs or (z) a Disruption Event occurs; provided that the parties agree that any repurchase of Shares pursuant to this Transaction shall not be considered a Potential Adjustment Event.  In the case of any event described in clause (x), (y) or (z) above occurs, the Calculation Agent may, in its commercially reasonable judgment, adjust any relevant terms of such Transaction as necessary to preserve as nearly as practicable the fair value of such Transaction prior to such Valuation Disruption Postponement, Regulatory Disruption or Disruption Event, as the case may be.

		
	Excess Dividend:
	For any calendar quarter, any cash dividend or cash distribution on the Shares with an ex-dividend date occurring during such calendar quarter (other than any dividend or distribution of the type described in Section 11.2(e)(i) or Section 11.2(e)(ii)(A) of the Equity Definitions or any Extraordinary Dividend or any dividend of any rights pursuant to the adoption by the Counterparty of a stockholder rights plan during the term of the Transaction) (a “Dividend”) the amount or value of which per Share (as determined by the Calculation Agent in good faith and in a commercially reasonable manner), when aggregated with the amount or value (as determined by the Calculation Agent) of any and all previous cash Dividends with ex-dividend dates occurring in the same calendar quarter, exceeds the Ordinary Dividend Amount. “Extraordinary Dividend” means the per Share cash dividend or distribution, or a portion thereof, declared by Counterparty on the Shares that is classified by the board of directors of Counterparty as a “special” or an “extraordinary” dividend and any declaration thereof by the Counterparty shall be subject to Section 23 of this Confirmation.

		
	Consequences of Excess Dividend:
	The declaration by the Issuer of any Excess Dividend, the ex-dividend date for which occurs or is scheduled to occur during the Relevant Dividend Period for any Transaction, shall, at Dealer’s election in its sole judgment, either (x) constitute an Additional Termination Event in respect of such Transaction, with Counterparty as the sole Affected Party and such Transaction as the sole Affected Transaction or (y) result in an adjustment, by the Calculation Agent, to the Floor Price as the Calculation Agent determines in a good faith and commercially reasonable manner appropriate to account for the economic effect on such Transaction of such Excess Dividend; provided, that Dealer’s election to treat such Excess Dividend as either an Additional Termination Event or an adjustment to the Floor Price (but not both) must be made within 30 days after the first public announcement of such Excess Dividend.

		
	Ordinary Dividend Amount:
	For each Transaction, as set forth in the related Supplemental Confirmation.

		
	Method of Adjustment:
	Calculation Agent Adjustment 

		
	Early Ordinary Dividend Payment:
	For each Transaction, if an ex-dividend date for any Dividend that is not (w) an Excess Dividend, (x) a dividend or distribution of the type described in Section 11.2(e)(i) or Section 11.2(e)(ii)(A) of the Equity Definitions, (y) any dividend of any rights pursuant to the adoption by the Counterparty of a stockholder rights plan during the term of the Transaction and (z) an Extraordinary Dividend, occurs during any calendar quarter occurring (in whole or in part) during the Relevant Dividend Period for such Transaction and is prior to the Scheduled Ex-Dividend Date for such Transaction for the relevant calendar quarter (as determined by the Calculation Agent), the Calculation Agent shall make such adjustment to the exercise, settlement, payment or any other terms of the relevant Transaction as the Calculation Agent determines in a good faith and commercially reasonable manner appropriate to account for the economic effect on such Transaction of such event.

		
	Scheduled Ex-Dividend Dates:
	For each Transaction, as set forth in the related Supplemental Confirmation for each calendar quarter.

		
	Relevant Dividend Period:
	For each Transaction, the period from, and including, the Trade Date for such Transaction to, and including, the Relevant Dividend Period End Date for such Transaction.  

		
	Relevant Dividend Period End Date:
	For each Transaction, if the Number of Shares to be Delivered for such Transaction is negative, the last day of the Settlement Valuation Period; otherwise, the Termination Date for such Transaction.

Notwithstanding anything to the contrary in the Equity Definitions, a Change in Law described in clause (Y) of Section 12.9(a)(ii) of the Equity Definitions shall not constitute a Change in Law and instead shall constitute an Increased Cost of Hedging as described in Section 12.9(a)(vi) of the Equity Definitions.

	The Shares are not, and Counterparty will not cause the Shares to be, subject to a “restricted period” (as defined in Regulation M promulgated under the Exchange Act) (excluding for the purposes of this provision any issuances by the Counterparty of securities or undertaking of activities exempted from Regulation M by means of Rule 102(b), (c) or (d) of Regulation M (as defined below)) at any time during any Regulation M Period for any Transaction unless Counterparty has provided written notice to Dealer of such restricted period not later than the Scheduled Trading Day immediately preceding the first day of such “restricted period”; Counterparty acknowledges that any such notice may be treated as a Regulatory Disruption pursuant to Section 7 below; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 8 below.  Counterparty is not currently contemplating any “distribution” (as defined in Regulation M promulgated under the Exchange Act) of Shares, or any security for which Shares are a “reference security” (as defined in Regulation M promulgated under the Exchange Act).  “Regulation M Period” means, for any Transaction, (A) the Relevant Period (as defined below) for such Transaction, (B) the Settlement Valuation Period, if any, for such Transaction and (C) the Seller Termination Purchase Period (as defined below), if any, for such Transaction.  “Relevant Period” means, for any Transaction, the period commencing on the Calculation Period Start Date for such Transaction and ending on the later of (1) the earlier of (x) the Scheduled Termination Date and (y) the last Additional Relevant Day (as specified in the related Supplemental Confirmation) for such Transaction, or such earlier day as elected by Dealer and communicated to Counterparty on such day (or, if later, the First Acceleration Date without regard to any acceleration thereof pursuant to “Special Provisions for Acquisition Transaction Announcements” below) and (2) if Section 15 is applicable to such Transaction, the date on which all deliveries owed pursuant to Section 15 have been made. 

		
	(viii)
	As of the Trade Date, the Prepayment Date, the Initial Share Delivery Date, the Settlement Date, any Cash Settlement Payment Date and any Settlement Method Election Date for each Transaction, Counterparty is not “insolvent” (as such term is defined under Section 101(32) of the U.S.  Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)) and Counterparty would be able to purchase a number of Shares with a value equal to the Prepayment Amount in compliance with the laws of the jurisdiction of Counterparty’s incorporation.  

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

		
	(x)
	Counterparty shall, at least one day prior to the first day of the Calculation Period, the Settlement Valuation Period, if any, or the Seller Termination Purchase Period, if any, for any Transaction, notify Dealer of the total number of Shares purchased in Rule 10b-18 purchases of blocks pursuant to the once-a-week block exception set forth in paragraph (b)(4) of Rule 10b-18 under the Exchange Act (“Rule 10b-18”) by or for Counterparty or any of its “affiliated purchasers” (as defined in Rule 10b-18) during each of the four calendar weeks preceding such day and during the calendar week in which such day occurs (“Rule 10b-18 purchase” and “blocks” each being used as defined in Rule 10b-18), which notice shall be substantially in the form set forth in Schedule B hereto.

		
	(xi)
	As of the Trade Date for each Transaction hereunder, and as of the date of any election with respect to any Transaction hereunder, there has not been any Merger Announcement (as defined below).

		
	(c)
	In addition to the representations, warranties and covenants in this Agreement, Dealer represents, warrants and covenants to Counterparty that:

		
	(i)
	In addition to the covenants in the Agreement and herein, Dealer agrees to use commercially reasonable efforts, during the Calculation Period and any Settlement Valuation Period (as defined in Annex A) for any Transaction, to make all purchases of Shares in connection with such Transaction in a manner that would comply with the limitations set forth in clauses (b)(1), (b)(2), (b)(3) and (b)(4) and (c) of Rule 10b-18, as if such rule were applicable to such purchases and 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 Dealer’s control; provided that, during the Calculation Period, the foregoing agreement shall not apply to purchases made to dynamically hedge for Dealer’s own account or the account of its affiliate(s) the optionality arising under a Transaction (including, for the avoidance of doubt, timing optionality); provided further that, without limiting the generality of the first sentence of this Section 6(c)(i), Dealer shall not be responsible for any failure to comply with Rule 10b-18(b)(3) to the extent any transaction that was executed (or deemed to be executed) by or on behalf of Counterparty or an “affiliated purchaser” (as defined under Rule 10b-18) pursuant to a separate agreement is not deemed to be an “independent bid” or an “independent transaction” for purposes of Rule 10b-18(b)(3).

		
	(ii)
	In connection with each Transaction, Dealer represents and warrants to Counterparty that it has not, at any time before the filing of a Form 8-K reporting the entry into such Transaction on the Trade Date for such Transaction, discussed any offsetting transaction(s) in respect of such Transaction with any third party.

		
	(iii)
	Dealer hereby represents and covenants to Counterparty that it has implemented policies and procedures, taking into consideration the nature of its business, reasonably designed to ensure that individuals making investment decisions related to any Transaction do not have access to material nonpublic information regarding Issuer or the Shares. 

		
	(iv)
	Within one Exchange Business Day of purchasing any Shares on behalf of Counterparty pursuant to the once-a-week block exception set forth in paragraph (b)(4) of Rule 10b-18, Dealer shall notify Counterparty of the total number of Shares so purchased.

		
	(v)
	On the first Exchange Business Day of each week, Dealer shall provide weekly reports (the “Weekly Reports”) in connection with such Transaction to the Counterparty and to such other persons or agents of the Counterparty as the Counterparty shall reasonably designate in writing, by electronic mail to the Counterparty or its designee.  Each weekly report shall include the ADTV in the Shares for each Scheduled Trading Day during the immediately preceding week (as defined and determined in accordance with Rule 10b-18, as defined herein), the VWAP Price for each such Scheduled Trading Day and the high and low price on each such Scheduled Trading Day.  For the avoidance of doubt and notwithstanding anything to the contrary in the two immediately preceding sentences, the VWAP Price for purposes of this Master Confirmation shall be determined pursuant the language opposite the caption “VWAP Price” in Section 1 of this Master Confirmation under the heading “Valuation” and not on the basis of, or by reference to, the VWAP Price set forth in any Weekly Report.

		
	7.
	Regulatory Disruption.  In the event Dealer concludes, in its good faith, reasonable judgment, based on the advice of counsel, that it is appropriate with respect to any legal, regulatory or self-regulatory requirements or related policies and procedures similarly applicable to accelerated share repurchase transactions and consistently applied (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer) (provided that such requirements, policies and procedures relate to regulatory issues and are generally applicable in similar situations and are applied in a consistent manner in similar transactions) for it to refrain from or decrease any market activity on any Scheduled Trading Day or Days during the Calculation Period or, if applicable, the Settlement Valuation Period, Dealer may, in its commercially reasonable discretion, by written notice to Counterparty elect to deem that a Market Disruption Event has occurred and will be continuing on such Scheduled Trading Day or Days.  Dealer shall notify Counterparty as soon as practicable (but in no event later than one Trading Day) that a Regulatory Disruption has occurred and the reasons for such Regulatory Disruption and the Scheduled Trading Days affected by it, provided that the Dealer shall not be obligated to disclose any proprietary or confidential models or any other confidential or proprietary information, in each case, used by it for such determination.

		
	8.
	10b5-1 Plan.  Counterparty represents, warrants and covenants to Dealer that: 

		
	(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”) or any other antifraud or anti-manipulation provisions of the federal or applicable state securities laws and that it has not entered into or altered and will not enter into or alter any corresponding or hedging transaction or position with respect to the Shares.  Counterparty acknowledges that it is the intent of the parties that each Transaction entered into under this Master Confirmation comply with the requirements of paragraphs (c)(1)(i)(A) and (B) of Rule 10b5-1 and each Transaction entered into under this Master Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c).

		
	(b)
	During the Calculation Period and the Settlement Valuation Period, if any, for any Transaction and in connection with the delivery of any Alternative Delivery Units for any Transaction, Dealer (or its agent or Affiliate) may effect transactions in Shares in connection with such Transaction.  The timing of such transactions by Dealer, the price paid or received per Share pursuant to such transactions and the manner in which such transactions are made, including, without limitation, whether such transactions are made on any securities exchange or privately, shall be within the sole judgment of Dealer.  Counterparty acknowledges and agrees that all such transactions shall be made in Dealer’s sole judgment and for Dealer’s own account.

		
	(c)
	Counterparty does not have, and shall not attempt to exercise, any control or influence over how, when or whether Dealer (or its agent or Affiliate) makes any “purchases or sales” (within the meaning of Rule 10b5-1(c)(1)(i)(B)(3)) in connection with any Transaction, including, without limitation, over how, when or whether Dealer (or its agent or Affiliate) enters 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 and each Supplemental Confirmation under Rule 10b5-1.  

		
	(d)
	Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of this Master Confirmation or any Supplemental Confirmation 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 or waiver 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.  

		
	(e)
	Counterparty shall not, directly or indirectly, communicate any information relating to the Shares or any Transaction (including, without limitation, any notices required by Section 10(a)) to any employee of Dealer, other than as set forth in the Communications Procedures attached as Annex B hereto.

		
	9.
	Counterparty Purchases.  Counterparty (or any “affiliate” or “affiliated purchaser” as defined in Rule 10b-18) shall not, without the prior written consent of Dealer, directly or indirectly (including, without limitation, by means of a 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 equivalent interest, including, without limitation, a unit of beneficial interest in a trust or limited partnership or a depository share), 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 Relevant Period, any Settlement Valuation Period (if applicable) or any Seller Termination Purchase Period (if applicable), under this Master Confirmation.  

Notwithstanding the immediately preceding paragraph or anything herein to the contrary (i) an agent independent of Counterparty may purchase Shares effected by or for an issuer plan Counterparty in accordance with the requirements of Section 10b-18(a)(13)(ii) under the Exchange Act (with “issuer plan” and “agent independent of Counterparty” each being used herein as defined in Rule 10b-18), and (ii) Counterparty or any “affiliated purchaser” may purchase Shares in (x) unsolicited transactions or (y) privately negotiated (off-market) transactions, in each case, that are not “Rule 10b-18 purchases” (as defined in Rule 10b-18), in each case, without Dealer’s consent.
Nothing in this Section 9 will (i) limit the Counterparty’s ability, pursuant to its employee incentive plans or dividend reinvestment program, to reacquire Shares in connection with the related equity transactions, (ii) limit Counterparty’s ability to withhold shares to cover tax liabilities associated with such equity transaction, or (iii) limit Counterparty’s ability to grant stock, restricted stock units and options to “affiliated partners” (as defined in Rule 10b-18) or the ability of such affiliated purchasers to acquire such stock or options, in connection with the Counterparty’s compensation policies for directors, officers or employees of any entities that are acquisition targets of Counterparty, and in connection with such purchase Counterparty will be deemed to represent to Dealer that such purchase does not constitute a “Rule 10b-18 Purchase” (as defined in Rule 10b-18) (any such incentive or compensatory plan, program or policy of Counterparty, a “Compensatory Plan”) (collectively, “Permitted Purchases”).
		
	10.
	Special Provisions for Merger Transactions.  Notwithstanding anything to the contrary herein or in the Equity Definitions:

		
	(a)
	Counterparty agrees that it: 

		
	(i)
	will not during the period commencing on the Trade Date for any Transaction and ending on the last day of the Relevant Period or, if applicable, the later of the last day of the Settlement Valuation Period and the last day of the Seller Termination Purchase Period, for such Transaction make, or to the extent within Counterparty’s reasonable control, permit to be made, any public announcement (as defined in Rule 165(f) under the Securities Act) of any Merger Transaction or potential Merger Transaction (a “Merger Announcement”) unless such Merger Announcement is made prior to the opening or after the close of the regular trading session on the Exchange for the Shares; provided that, upon any Merger Announcement during such period, as applicable, that is made at any time other than prior to the opening or after the close of the regular trading session on the Exchange for the Shares, the provisions of Section 6(c)(i) hereof shall no longer apply to Dealer; 

		
	(ii)
	shall promptly (but in any event prior to the next opening of the regular trading session on the Exchange) notify Dealer following any such Merger Announcement that such Merger Announcement has been made; and 

		
	(iii)
	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 of any Merger Transaction or potential Merger Transaction 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 of any Merger Transaction or potential Merger Transaction.  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 shareowners.  

		
	(b)
	Counterparty acknowledges that any such Merger Announcement or delivery of a notice with respect thereto may cause the terms of any Transaction to be adjusted as a Regulatory Disruption or result in such Transaction being terminated; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 8 above.

		
	(c)
	Any such Merger Announcement or the receipt of a notice with respect thereto by the Dealer may be treated by the Dealer as a Regulatory Disruption and result in the terms of any Transaction being adjusted by the Dealer (solely to account for the economic effect of such Public Announcement on the Transaction as a result of such Regulatory Disruption) or result in such Transaction being treated as an Additional Termination Event by Dealer.

“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 pursuant to which the Dealer determines, in its reasonable discretion, that Dealer would be limited in purchasing Shares during the term of the Transaction under Rule 10b-18 in the same manner that Rule 10b-18 would limit the Counterparty from purchasing Shares of its Common Stock under Rule 10b-18, other than, solely for purposes of this Section 10, any such transaction in which the consideration consists solely of cash and there is no valuation period.
Any adjustment to the terms of any Transaction hereunder and the determination of any amounts due upon termination of any Transaction hereunder as a result of a Merger Transaction shall be made without duplication in respect of any prior adjustment hereunder (including, without limitation, any prior adjustment pursuant to Section 11 below).
		
	11.
	Special Provisions for Acquisition Transaction Announcements.  Notwithstanding anything to the contrary herein or in the Equity Definitions:

		
	(a)
	If an Acquisition Transaction Announcement occurs on or prior to the Settlement Date for any Transaction, then the Calculation Agent shall make such adjustment, in a commercially reasonable manner, to the Forward Price Adjustment Amount as the Calculation Agent determines appropriate, at such time as the Calculation Agent determines appropriate, to account for the economic effect on the Forward Price Adjustment Amount of such Acquisition Transaction Announcement in accordance with “Method of Adjustment” as set forth in Section 1 above, as amended pursuant to Section 22(a)-(c) of this Master Confirmation.

		
	(b)
	“Acquisition Transaction Announcement” means (i) the announcement of an Acquisition Transaction or an event that, if consummated, would result in an Acquisition Transaction, (ii) an announcement that Counterparty or any of its subsidiaries has entered into an agreement, a letter of intent or an understanding designed to result in an Acquisition Transaction, (iii) the announcement by the Counterparty or any of its subsidiaries of the intention to solicit or enter into, or to explore strategic alternatives or other similar undertaking that may include, an Acquisition Transaction, (iv) the announcement by a bona fide person of such person’s intention to pursue an Acquisition Transaction that in the good faith commercially reasonable judgment of the Calculation Agent may result in an Acquisition Transaction; provided that the Calculation Agent shall in good faith determine whether any such person is a bona fide person or (v) any announcement of any change or amendment to any previous Acquisition Transaction Announcement (including any announcement of the abandonment of any such previously announced Acquisition Transaction, agreement, letter of intent, understanding or intention).  

		
	(c)
	“Acquisition Transaction” means (i) any Merger Event (for purposes of this definition the definition of Merger Event shall be read with the references therein to “100%” being replaced by “30%” and references to “50%” being replaced by “75%” and without reference to the clause beginning immediately following the definition of Reverse Merger therein to the end of such definition), Tender Offer or Merger Transaction or any other transaction involving the merger of Counterparty with or into any third party, (ii) the sale or transfer of all or substantially all of the assets of Counterparty, (iii) a recapitalization, reclassification, binding share exchange or other similar transaction with respect to Counterparty, (iv) any lease, exchange, transfer, disposition (including, without limitation, by way of spin-off or distribution) of assets (including, without limitation, any capital stock or other ownership interests in subsidiaries) or other similar event by Counterparty or any of its subsidiaries where the aggregate consideration transferable or receivable by or to Counterparty or its subsidiaries exceeds 25% of the market capitalization of Counterparty (measured as of the relevant date of announcement) or (v) any transaction in which Counterparty or its board of directors has a legal obligation to make a recommendation to its shareowners in respect of such transaction (whether pursuant to Rule 14e-2 under the Exchange Act or otherwise).  

Any adjustment to the terms of any Transaction hereunder as a result of an Acquisition Transaction Announcement shall be made without duplication in respect of any prior adjustment hereunder (including, without limitation, any prior adjustment pursuant to Section 10 above).

	(b)
	Counterparty acknowledges that:

		
	(i)
	during the term of any Transaction, Dealer and its Affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to establish, adjust or unwind its hedge position with respect to such Transaction;

	13.
	No Collateral, Netting or Setoff.  Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Counterparty hereunder are not secured by any collateral.  Obligations under any 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 Master Confirmation or any Supplemental Confirmation, or 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 any Transaction, whether arising under the Agreement, this Master Confirmation or any Supplemental Confirmation, or 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.

		
	14.
	Delivery of Shares.  Notwithstanding anything to the contrary herein, Dealer may, by prior notice to Counterparty, satisfy its obligation to deliver any Shares or other securities on any date due (an “Original Delivery Date”) by making separate deliveries of Shares or such securities, as the case may be, at more than one time on or prior to such Original Delivery Date, so long as the aggregate number of Shares and other securities so delivered on or prior to such Original Delivery Date is equal to the number required to be delivered on such Original Delivery Date.  

		
	15.
	Alternative Termination Settlement.  In the event that (a) 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 or (b) any Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists solely of cash, (ii) a Merger Event or Tender Offer that is within Counterparty’s control, or (iii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event of Default arising solely from a failure to comply with Section 6(b)(vi) of this Master Confirmation, an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s control), if either party would owe any amount to the other party 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 Amount”), then, in lieu of any payment of such Payment Amount, unless Counterparty makes an election to the contrary no later than the Early Termination Date or the date on which such Transaction is terminated or cancelled, Counterparty or Dealer, as the case may be, shall deliver to the other party a number of Shares (or, in the case of a Nationalization, Insolvency or 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 Nationalization, Insolvency or Merger Event, as the case may be (each such unit, an “Alternative Delivery Unit”) with a value equal to the Payment Amount, as determined by the Calculation Agent in good faith and in a commercially reasonably manner over a commercially reasonable period of time (and the parties agree that, in making such determination of value, the Calculation Agent may take into account a number of factors, including, without limitation, the market price of the Shares or Alternative Delivery Units on the Early Termination Date or the date of early cancellation or termination, as the case may be, and, if such delivery is made by Dealer, the prices at which Dealer purchases Shares or Alternative Delivery Units on any Exchange Business Day to fulfill its delivery obligations under this Section 15); provided that in determining the composition of any Alternative Delivery Unit, if the relevant Nationalization, Insolvency or Merger Event involves a choice of consideration to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash; and provided further that Counterparty may elect that the provisions of this Section 15 above providing for the delivery of Shares or Alternative Delivery Units, as the case may be, shall not apply only if Counterparty represents and warrants to Dealer, in writing on the date it notifies Dealer of such election, that, as of such date, Counterparty is not aware of any material non-public information regarding Counterparty or the Shares and is 

making such election in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws.  If delivery of Shares or Alternative Delivery Units, as the case may be, pursuant to this Section 15 is to be made by Counterparty, paragraphs 2 through 7 of Annex A hereto shall apply as if (A) such delivery were a settlement of such Transaction to which Net Share Settlement applied, (B) the Cash Settlement Payment Date were the Early Termination Date or the date of early cancellation or termination, as the case may be, and (C) the Forward Cash Settlement Amount were equal to (x) zero minus (y) the Payment Amount owed by Counterparty.  For the avoidance of doubt, if Counterparty validly elects for the provisions of this Section 15 relating to the delivery of Shares or Alternative Delivery Units, as the case may be, not to apply to any Payment Amount, the provisions of Article 12 of the Equity Definitions, or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.  If delivery of Shares or Alternative Delivery Units, as the case may be, is to be made by Dealer pursuant to this Section 15, the period during which Dealer purchases Shares or Alternative Delivery Units to fulfill its delivery obligations under this Section 15 shall be referred to as the “Seller Termination Purchase Period”.

		
	16.
	Calculations and Payment Date upon Early Termination.  The parties acknowledge and agree that in calculating (a) the Close-Out Amount pursuant to Section 6 of the Agreement and (b) the amount due upon cancellation or termination of any Transaction (whether in whole or in part) pursuant to Article 12 of the Equity Definitions as a result of an Extraordinary Event, Dealer may (but need not) determine such amount based on (i) expected losses assuming a commercially reasonable (including, without limitation, with regard to reasonable legal and regulatory guidelines customary for transactions of this type) risk bid were used to determine loss or (ii) the price at which one or more market participants would offer to sell to the Seller a block of shares of Common Stock equal in number to the Seller’s hedge position in relation to the Transaction.  Notwithstanding anything to the contrary in Section 6(d)(ii) of the Agreement or Article 12 of the Equity Definitions, all amounts calculated as being due in respect of an Early Termination Date under Section 6(e) of the Agreement or upon cancellation or termination of the relevant Transaction under Article 12 of the Equity Definitions will be payable on the day that notice of the amount payable is effective; provided that if Counterparty elects to receive or deliver Shares or Alternative Delivery Units in accordance with Section 15, such Shares or Alternative Delivery Units shall be delivered on a date selected by Dealer as promptly as practicable.

		
	17.
	Limit on Beneficial Ownership.  Notwithstanding anything to the contrary in this Master Confirmation, Counterparty acknowledges and agrees that, on any day, Dealer shall not be obligated to receive from Counterparty any Shares, and Counterparty shall not be entitled to deliver to Dealer any Shares, to the extent (but only to the extent) that after such transactions Dealer’s ultimate parent entity would directly or indirectly “beneficially own” (as such term is defined for purposes of Section 13(d) of the Exchange Act) at any time on such day in excess of 8% of the outstanding Shares.  Any purported receipt of Shares shall be void and have no effect to the extent (but only to the extent) that after such receipt, Dealer’s ultimate parent entity would directly or indirectly so beneficially own in excess of 8% of the outstanding Shares.  If, on any day, any receipt of Shares by Dealer is not effected, in whole or in part, as a result of this Section 17, Counterparty’s obligations to deliver such Shares shall not be extinguished and any such delivery shall be effected over time by Counterparty as promptly as Dealer determines, such that after any such delivery, Dealer’s ultimate parent entity would not directly or indirectly beneficially own in excess of 8% of the outstanding Shares.

		
	18.
	Maximum Share Delivery.  Notwithstanding anything to the contrary in this Master Confirmation, in no event shall Dealer be required to deliver any Shares, or any Shares or other securities comprising Alternative Delivery Units, in respect of any Transaction in excess of the Maximum Number of Shares set forth in the Supplemental Confirmation for such Transaction.

		
	19.
	Additional Termination Events.

		
	(a)
	The occurrence of an event described in paragraph III of Annex B hereto will constitute an Additional Termination Event, with Counterparty as the sole Affected Party and the Transactions specified in such paragraph III as the Affected Transactions.

		
	(b)
	Notwithstanding anything to the contrary in Section 6 of the Agreement, if a Termination Price is specified in the Supplemental Confirmation for any Transaction, then an Additional Termination Event (with respect to which Counterparty shall be the sole Affected Party and such Transaction shall be the sole Affected Transaction) will occur without any notice or action by Dealer or Counterparty if, on two consecutive Exchange Business Days, the price of the Shares on the Exchange at any time falls below such Termination Price.

		
	20.
	Non-confidentiality.  Dealer and Counterparty hereby acknowledge and agree that, subject to Section 8(e), each is authorized to disclose the tax structure and tax treatment of the transactions contemplated by this Master Confirmation and any Supplemental Confirmation hereunder to any and all persons, without limitation of any kind, and there are no express or implied agreements, arrangements or understandings to the contrary.

		
	21.
	Assignment and Transfer.  Notwithstanding anything to the contrary in the Agreement, without the consent of Counterparty, Dealer may assign any of its rights or duties hereunder to any one or more of its Affiliates (1) that has a long-term issuer rating that is equal to or better than Dealer’s credit rating at the time of such assignment, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used generally for similar transactions, by Dealer or Dealer’s ultimate parent; provided that, at the time of such assignment (i) Counterparty will not be required to pay (including a payment in kind) to the transferee any amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement (except in respect of interest under Section 2(e), 6(d)(ii) or 6(e) of the Agreement) greater than the amount in respect of which Counterparty would have been required to pay to Dealer in the absence of such transfer; and (ii) Counterparty will not receive any payment (including a payment in kind) from which an amount had been withheld or deducted, on account of a Tax under Section 2(d)(i) of the Agreement (except in respect of interest under Section 2(e), 6(d)(ii) or 6(e) of the Agreement), in excess of that which Dealer would have been required to so withhold or deduct in the absence of such transfer, except to the extent that the transferee will be required to make additional payments pursuant to Section 2(d)(i)(4) of the Agreement in respect of such excess.  Notwithstanding any other provision in this Master Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Dealer may designate any of its Affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Dealer’s obligations in respect of any Transaction and any such designee may assume such obligations.  Dealer may assign the right to receive Settlement Shares to any third party who may legally receive Settlement Shares.  Dealer shall be discharged of its obligations to Counterparty only to the extent of any such performance.  For the avoidance of doubt, Dealer hereby acknowledges that notwithstanding any such designation hereunder, to the extent any of Dealer’s obligations in respect of any Transaction are not completed by its designee, Dealer shall be obligated to continue to perform or to cause any other of its designees to perform in respect of such obligations.

	Electing Party:
	Counterparty 

		
	Settlement Method Election Date:
	The earlier of (x) the second Exchange Business Day immediately following the Accelerated Termination Date (in which case election under Section 7.1 of the Equity Definitions shall be made no later than 10 minutes prior to the open of trading on the Exchange on such second Exchange Business Day) and (y) the Scheduled Termination Date (such earlier date, the “Scheduled Settlement Election Date”), unless, on the Scheduled Settlement Election Date, Counterparty is aware of any material, non-public information regarding Counterparty or the Shares, in which case the Settlement Method Election Date shall be the earlier of (x) the 30th calendar day immediately following the Scheduled Settlement Election Date and (y) the first date immediately following the Scheduled Settlement Election Date on which Counterparty is not aware of any material, non-public information regarding Counterparty or the Shares.

	Cash Settlement 

		
	Forward Cash Settlement Amount:

	Settlement Valuation Period:
	A number of Scheduled Trading Days selected by Dealer in its reasonable judgment, beginning on the Scheduled Trading Day immediately following the Termination Date.  Dealer shall notify Counterparty of the last Scheduled Trading Day of the Settlement Valuation Period on or prior to the Exchange Business Day immediately following such last Scheduled Trading Day.

	Net Share Settlement Procedures:
	If Net Share Settlement is applicable, Net Share Settlement shall be made in accordance with paragraphs 2 through 7 below.  

2.    Net Share Settlement shall be made by delivery on the Cash Settlement Payment Date of a number of Shares satisfying the conditions set forth in paragraph 3 below (the “Registered Settlement Shares”), or a number of Shares not satisfying such conditions (the “Unregistered Settlement Shares”), in either case with a value equal to 100.50% (in the case of Registered Settlement Shares) or 102.50% (in the case of Unregistered Settlement Shares) of the absolute value of the Forward Cash Settlement Amount, with such Shares’ value based on the value thereof to Dealer (which value shall, in the case of Unregistered Settlement Shares, take into account a commercially reasonable illiquidity discount), in each case as determined by the Calculation Agent in good faith and a commercially reasonable manner.  If all of the conditions for delivery of either Registered Settlement Shares or Unregistered Settlement Shares have not been satisfied, Cash Settlement shall be applicable in accordance with paragraph 1 above notwithstanding Counterparty’s election of Net Share Settlement.
3.    Counterparty may only deliver Registered Settlement Shares pursuant to paragraph 2 above if: 
(a)    a registration statement covering public resale of the Registered Settlement Shares by Dealer (the “Registration Statement”) shall have been filed with the Securities and Exchange Commission under the Securities Act and been declared or otherwise become effective on or prior to the date of delivery, and no stop order shall be in effect with respect to the Registration Statement; a printed prospectus relating to the Registered Settlement Shares (including, without limitation, any prospectus supplement thereto, the “Prospectus”) shall have been delivered to Dealer, in such quantities as Dealer shall reasonably have requested, on or prior to the date of delivery; 
(b)    the form and content of the Registration Statement and the Prospectus (including, without limitation, any sections describing the plan of distribution) shall be reasonably satisfactory to Dealer; 
(c)    as of or prior to the date of delivery, Dealer and its agents shall have been afforded a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities for companies of a similar size in a similar industry (provided that prior to receiving or being granted access to any such information, Dealer and any such agent may be required by Counterparty to enter into a customary nondisclosure agreement with Counterparty in respect of any such due diligence investigation) and the results of such investigation are satisfactory to Dealer, in its judgment; and 
(d)    as of the date of delivery, an agreement (the “Underwriting Agreement”) shall have been entered into with Dealer in connection with the public resale of the Registered Settlement Shares by Dealer substantially similar to underwriting agreements customary for underwritten offerings of equity securities for companies of a similar size in a similar industry, in form and substance reasonably satisfactory to Dealer, which Underwriting Agreement shall include, without limitation, provisions substantially similar to those contained in such underwriting agreements relating, without limitation, to the mutual indemnification of, and contribution in connection with the liability of, the parties and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters.  
4.    If Counterparty delivers Unregistered Settlement Shares pursuant to paragraph 2 above: 
(a)    all Unregistered Settlement Shares shall be delivered to Dealer (or any Affiliate of Dealer designated by Dealer) pursuant to the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof; 
(b)    as of or prior to the date of delivery, Dealer and any potential purchaser of any such shares from Dealer (or any Affiliate of Dealer designated by Dealer) identified by Dealer shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for private placements of equity securities of similar size by issuers similar to Counterparty (including, without limitation, the right to have made available to them for inspection all relevant financial and other records, pertinent corporate documents and other information reasonably requested by them); provided that prior to receiving or being granted access to any such information, any such Dealer (or Affiliate) or potential purchaser may be required by Counterparty to enter into a customary nondisclosure agreement with Counterparty in respect of any such due diligence investigation;

(c)    as of the date of delivery, Counterparty shall enter into an agreement (a “Private Placement Agreement”) with Dealer (or any Affiliate of Dealer designated by Dealer) in connection with the private placement of such shares by Counterparty to Dealer (or any such Affiliate) and the private resale of such shares by Dealer (or any such Affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities for companies of a similar size in a similar industry, in form and substance commercially reasonably satisfactory to Dealer, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating, without limitation, to the mutual indemnification of, and contribution in connection with the liability of, the parties and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters, and shall provide for the payment by Counterparty of all reasonable fees and actual, documented out-of-pocket expenses of Dealer (and any such Affiliate) in connection with such resale, including, without limitation, all reasonable fees and actual, documented out-of-pocket expenses of counsel for Dealer, and shall contain representations, warranties, covenants and agreements of the parties reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales; and 
(d)    in connection with the private placement of such shares by Counterparty to Dealer (or any such Affiliate) and the private resale of such shares by Dealer (or any such Affiliate), Counterparty shall, if so requested by Dealer, prepare, in cooperation with Dealer, a private placement memorandum in form and substance reasonably satisfactory to Dealer for companies of a similar size and in a similar industry.  
5.    Dealer, itself or through an Affiliate (the “Selling Agent”) or any underwriter(s), will sell all, or such lesser portion as may be required hereunder, of the Registered Settlement Shares or Unregistered Settlement Shares and any Makewhole Shares (as defined below) (together, the “Settlement Shares”) delivered by Counterparty to Dealer pursuant to paragraph 6 below commencing on the Cash Settlement Payment Date and continuing until the date on which the aggregate Net Proceeds (as such term is defined below) of such sales, as determined by Dealer, is equal to the absolute value of the Forward Cash Settlement Amount (such date, the “Final Resale Date”).  If Counterparty is prohibited by law or by contract from disclosing all material non-public information known to Counterparty with respect to Counterparty and the Shares to any potential purchasers of such Settlement Shares, then the sale of such Settlement Shares shall not be required to commence until the earlier of (x) the 30th calendar day immediately following the Cash Settlement Payment Date and (y) the first date immediately following the Cash Settlement Payment Date on which Counterparty reasonably concludes that it is able to disclose such information.  If the proceeds of any sale(s) made by Dealer, the Selling Agent or any underwriter(s), net of any commercially reasonable fees and commissions (including, without limitation, underwriting or placement fees) customary for similar transactions under the circumstances at the time of the offering, together with commercially reasonable carrying charges and expenses incurred in connection with the offer and sale of the Shares (including, without limitation, the covering of any over-allotment or short position (syndicate or otherwise)) (the “Net Proceeds”) exceed the absolute value of the Forward Cash Settlement Amount, Dealer will refund, in USD, such excess to Counterparty on the date that is three (3) Currency Business Days following the Final Resale Date, and, if any portion of the Settlement Shares remains unsold, Dealer shall return to Counterparty on that date such unsold Shares.  
6.    If the Calculation Agent determines that the Net Proceeds received from the sale of the Registered Settlement Shares or Unregistered Settlement Shares or any Makewhole Shares, if any, pursuant to this paragraph 6 are less than the absolute value of the Forward Cash Settlement Amount (the amount in USD by which the Net Proceeds are less than the absolute value of the Forward Cash Settlement Amount being the “Shortfall” and the date on which such determination is made, the “Deficiency Determination Date”), Counterparty shall on the Exchange Business Day next succeeding the Deficiency Determination Date (the “Makewhole Notice Date”) deliver to Dealer, through the Selling Agent, a notice of Counterparty’s election that Counterparty shall either (i) pay an amount in cash equal to the Shortfall on the day that is one Currency Business Day after the Makewhole Notice Date, or (ii) deliver additional Shares.  If Counterparty elects to deliver to Dealer additional Shares, then Counterparty shall deliver additional Shares in compliance with the terms and conditions of paragraph 3 or paragraph 4 above, as the case may be (the “Makewhole Shares”), on the first Clearance System Business Day which is also an Exchange Business Day following the Makewhole Notice Date in such number as the Calculation Agent reasonably believes would have a market value on that Exchange Business Day equal to the Shortfall.  Such Makewhole Shares shall be sold by Dealer in accordance with the provisions above; provided that if the sum of the Net Proceeds from the sale of the originally delivered Shares and the Net Proceeds from the sale of any Makewhole Shares is less than the absolute value of the Forward Cash Settlement Amount then Counterparty shall, at its election, either make such cash payment or deliver to Dealer further Makewhole Shares until such Shortfall has been reduced to zero.  
7.    Notwithstanding the foregoing, in no event shall the aggregate number of Settlement Shares for any Transaction be greater than the Reserved Shares minus the amount of any Shares actually delivered by Counterparty under any other Transaction under this Master Confirmation (the result of such calculation, the “Capped Number”).  Counterparty represents and warrants (which shall be deemed to be repeated on each day that a Transaction is outstanding) that the Capped Number is equal to or less than the number of Shares determined according to the following formula: 

A - B
		
	Where
	A  =     the number of authorized but unissued shares of Counterparty that are not reserved for future issuance on the date of the determination of the Capped Number; and

B  =     the maximum number of Shares required to be delivered to third parties if Counterparty elected Net Share Settlement of all transactions in the Shares (other than Transactions in the Shares under this Master Confirmation) with all third parties that are then currently outstanding and unexercised.  
“Reserved Shares” means, for each Transaction, as set forth in the Supplemental Confirmation for such Transaction.
If at any time, as a result of this paragraph 7, Counterparty fails to deliver to Dealer any Settlement Shares, Counterparty shall, to the extent that Counterparty has at such time authorized but unissued Shares not reserved for other purposes, promptly notify Dealer thereof and deliver to Dealer a number of Shares not previously delivered as a result of this paragraph 7.

ANNEX B
COMMUNICATIONS PROCEDURES

October 26, 2015

I.    Introduction
Rambus, Inc. (“Counterparty”) and Citibank, N.A. (“Dealer”) have adopted these communications procedures (the “Communications Procedures”) in connection with entering into the Master Confirmation (the “Master Confirmation”), dated as of October 26, 2015, between Dealer and Counterparty relating to Uncollared Accelerated Share Repurchase transactions.  These Communications Procedures supplement, form part of, and are subject to the Master Confirmation.
II.    Communications Rules
For each Transaction, from the Trade Date for such Transaction until the date all payments or deliveries of Shares have been made with respect to such Transaction, Counterparty and its Employees and Designees shall not engage in any Program-Related Communication with, or disclose any Material Non-Public Information to, any Trading Personnel.  Except as set forth in the preceding sentence, the Master Confirmation shall not limit Counterparty and its Employees and Designees in their communication with Affiliates and Employees of Dealer, including, without limitation, Employees who are Permitted Contacts.
III.    Termination
If, in the reasonable judgment of any Trading Personnel or any Affiliate or Employee of Dealer participating in any Communication with Counterparty or any Employee or Designee of Counterparty, such Communication would not be permitted by these Communications Procedures, such Trading Personnel or Affiliate or Employee of Dealer shall immediately terminate such Communication.  In such case, or if such Trading Personnel or Affiliate or Employee of Dealer determines following completion of any Communication with Counterparty or any Employee or Designee of Counterparty that such Communication was not permitted by these Communications Procedures, such Trading Personnel or such Affiliate or Employee of Dealer shall promptly consult with his or her supervisors and with counsel for Dealer regarding such Communication.  If, in the reasonable judgment of Dealer’s counsel following such consultation, there is more than an insignificant risk that such Communication could materially jeopardize the availability of the affirmative defenses provided in Rule 10b5-1 under the Exchange Act with respect to any ongoing or contemplated activities of Dealer or its Affiliates in respect of any Transaction pursuant to the Master Confirmation, it shall be an Additional Termination Event pursuant to Section 19(a) of the Master Confirmation, with Counterparty as the sole Affected Party and all Transactions under the Master Confirmation as Affected Transactions.    
IV.    Definitions

	Re:
	Terms of Separation

Dear Kevin: 
This letter confirms the agreement between you and Rambus Inc. (“the Company”) concerning the terms of your separation and offers you the separation and transition benefits set forth below in exchange for a general release of claims and covenant not to sue (“Agreement”).

1.Separation Date; Transition Period and Services:  If you enter into this Agreement, and it becomes effective, January 4, 2016 will be your last day of employment with the Company (the “Separation Date”).  

2.Acknowledgment of Payment of Wages:  On January 4, 2016, we will provide you a final paycheck for all wages, salary, bonuses, commissions, reimbursements of ESPP contributions, and/or accrued, unused vacation due to you from the Company as of the Separation Date.  The Company will reimburse all reasonable expenses incurred in the normal course of business through the Separation Date pursuant to the terms of its expense reimbursement policy.  You will receive all funds owed pursuant to this section regardless of whether or not you sign this Agreement.  Your signature below is further acknowledgement that the Company does not owe you any other amounts.

3.Separation Benefits:  In exchange for your agreement to the general release and waiver of claims and covenant not to sue set forth below, and your other promises herein, and after the Effective Date (as defined below) of this Agreement, the Company agrees to continue your employment on a transitional basis, and provide you with certain separation benefits, on the following terms:

a.Transition Period:  Between now and the Separation Date (the “Transition Period”), you agree to abide by your ongoing obligations to the Company, including as described in Section 5 below, and to perform transition services as may reasonably be requested by the Company, including transition of the responsibilities, duties, and knowledge relative to your position (collectively, the “Transition Services”).  

b.Transition Compensation and Benefits:  During the Transition Period, the Company will continue to pay you your current base salary and you will continue to be eligible to participate in benefits customarily afforded to other similarly situated employees, including participation in the Company-sponsored health benefits plan, to the fullest extent allowed by the governing plan, agreements, or policies.  

c.Severance:  Provided that you comply with the terms and conditions of the Transition Period and carry out your Transition Services cooperatively, and otherwise comply fully with your obligations under this Agreement, on the Separation Date, the Company will pay you a lump sum payment of $265,000.00, less applicable state and federal tax payroll deductions, within ten (10) business days following the Separation Date. 

d.COBRA:  Upon your timely election to continue your existing health benefits under COBRA, and provided you are otherwise eligible pursuant to the terms of COBRA and the Company’s health insurance plan, the Company will pay the insurance premiums to continue your existing medical, dental, vision and Employee Assistance Program (EAP) health benefits for twelve (12) months following the Separation Date. If as an active employee you were enrolled in a flex spending plan, you can continue through COBRA, but you will be responsible for making the payments (on an after tax basis).
 
c.    Job Search Assistance.  Upon your election of outplacement services within sixty (60) calendar days of the Separation Date, the Company will provide you twelve (12) months of outplacement assistance (from the date of your election) to assist you in your job search. 
d.    By signing below, you acknowledge that you are receiving the separation benefits outlined in this Section 3 in consideration for waiving your rights to claims referred to in this agreement and that you are not otherwise entitled to the separation benefits.

4.Return of Company Property:  You hereby warrant to the Company that no later than the Separation Date, you will return to the Company all property or data of the Company of any type whatsoever that has been in your possession or control.

5.Confidential Information.  You hereby acknowledge that you are bound by the At Will Employment, Confidential Information, Invention Assignment and Arbitration Agreement (hereinafter referred to as the “ECIIA Agreement”), attached hereto as Exhibit A, and that as a result of your employment with the Company you had access to Confidential Information (as defined in the ECIIA Agreement), that you will hold all Confidential Information in strictest confidence and that you will not make use of such Confidential Information on behalf of anyone.  You further confirm that you will deliver to the Company all documents and data of any nature containing or pertaining to such Confidential Information by no later than the Separation Date and that you will not take with you any such documents or data or any reproduction thereof.  

6.General Release and Waiver of Claims:  

a.The payments and promises set forth in this agreement are in full satisfaction of all accrued salary, vacation pay, bonus and commission pay, profit sharing, stock options or other ownership interest in the Company, termination benefits or other compensation to which you may be entitled by virtue of your employment with the Company or your separation from the Company. To the fullest extent permitted by law, you hereby release and waive any other claims you may have against the Company and its owners, agents, officers, shareholders, employees, directors, attorneys, subscribers, subsidiaries, affiliates (including, without limitation, Rambus Delaware LLC), successors and assigns (collectively “Releasees”), whether known or not known, including, without limitation, claims under any employment laws, including, but not limited to, claims of unlawful discharge, breach of contract, breach of the covenant of good faith and fair dealing, fraud, violation of public policy, defamation, physical injury, emotional distress, claims for additional compensation or benefits arising out of your employment or your separation of employment, claims under Title VII of the 1964 Civil Rights Act, as amended, the California Fair Employment and Housing Act, and any other laws and/or regulations relating to employment or employment discrimination, including, without limitation, claims based on age or under the Age Discrimination in Employment Act or Older Workers Benefit Protection Act, and/or claims based on disability or under the Americans with Disabilities Act.  You further agree that any claims you may have for money damages, loss of wages, earnings, commission, bonuses and benefits, stock options or other ownership interests in the Company, medical expenses, attorneys’ fees and costs, reinstatement and other equitable relief, are waived and forever released by you under this Agreement.

b.By signing below, you expressly waive any benefits of Section 1542 of the Civil Code of the State of California, which provides as follows:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.”
c.     You are not releasing claims that you may not release as a matter of law, including but not limited to claims for indemnity under California Labor Code section 2802 or any claims to enforce this Agreement.   To the fullest extent permitted by law, any dispute regarding the scope of this general release shall be determined by an arbitrator under the procedures set forth in the arbitration clause below.
7.Covenant Not to Sue:  

a.    To the fullest extent permitted by law, at no time subsequent to the execution of this Agreement will you pursue, or cause or knowingly permit the prosecution, in any state, federal or foreign court, or before any local, state, federal or foreign administrative agency, or any other tribunal, any charge, claim or action of any kind, nature and character whatsoever, known or unknown, which you may now have, have ever had, or may in the future have against Releasees, which is based in whole or in part on any matter covered by this Agreement.  
b.    Nothing in this section shall prohibit you from filing a charge or complaint with a government agency where, as a matter of law, the parties may not restrict your ability to file such administrative complaints.  You further understand and agree that, by entering into this Agreement, you are releasing any and all individual claims for relief, and that any and all subsequent disputes between you and the Company shall be resolved through arbitration as provided below.

c.    Nothing in this section shall prohibit or impair you or the Company from complying with all applicable laws, nor shall this Agreement be construed to obligate either party to commit (or aid or abet in the commission of) any unlawful act.
8.    Nondisparagement:  You agree that you will not disparage Releasees or their products, services, agents, representatives, directors, officers, shareholders, attorneys, employees, vendors, affiliates, successors or assigns, or any person acting by, through, under or in concert with any of them, with any written or oral statement.  Nothing in this section shall prohibit you from lawfully providing truthful information in response to a subpoena or other legal process.   
9.    Arbitration:  Except for any claim for injunctive relief arising out of a breach of a party’s obligations to protect the other’s proprietary information, the parties agree to arbitrate, in Santa Clara County, California through JAMS, any and all disputes or claims arising out of or related to the validity, enforceability, interpretation, performance or breach of this Agreement, whether sounding in tort, contract, statutory violation or otherwise, or involving the construction or application or any of the terms, provisions, or conditions of this Agreement. Any arbitration may be initiated by a written demand to the other party.  The arbitrator's decision shall be final, binding, and conclusive.  The parties further agree that this Agreement is intended to be strictly construed to provide for arbitration as the sole and exclusive means for resolution of all disputes hereunder to the fullest extent permitted by law.  The parties expressly waive any entitlement to have such controversies decided by a court or a jury. 
10.    Attorneys’ Fees:  Except as prohibited by law, if any action is brought to enforce the terms of this Agreement, the prevailing party will be entitled to recover its reasonable attorneys’ fees, costs and expenses from the other party, in addition to any other relief to which the prevailing party may be entitled.
11.    Confidentiality:  You agree that the contents, terms and conditions of this Agreement must be kept confidential by you and may not be disclosed except to your immediate family members, accountants or attorneys, or pursuant to subpoena or court order. You further agree that if asked for information concerning this Agreement, you will state only that you and the Company reached an amicable resolution of any disputes concerning your separation from the Company. Any breach of this confidentiality provision shall be deemed a material breach of this Agreement.
12.    No Admission of Liability:  This Agreement is not and shall not be construed or contended by you to be an admission or evidence of any wrongdoing or liability on the part of Releasees, their representatives, heirs, executors, attorneys, agents, partners, officers, directors, employees, subsidiaries, affiliates, directors, successors or assigns. This Agreement shall be afforded the maximum protection allowable under California Evidence Code Section 1152 and/or any other state or federal provisions of similar effect.
13.    Entire Agreement:  This Agreement constitutes the entire agreement between you and Releasees with respect to the subject matter hereof and supersedes all prior negotiations and agreements, whether written or oral, relating to such subject matter other than the ECIIA Agreement referred to in Section 5 above. You acknowledge that neither Releasees nor their agents or attorneys have made any promise, representation or warranty whatsoever, either express or implied, written or oral, which is not contained in this Agreement for the purpose of inducing you to execute the Agreement, and you acknowledge that you have executed this Agreement in reliance only upon such promises, representations and warranties as are contained herein.
14.    Severability:  The provisions of this Agreement are severable, and if any part of it is found to be invalid or unenforceable, the other parts shall remain fully valid and enforceable.  Specifically, should a court, arbitrator, or government agency conclude that a particular claim may not be released as a matter of law, it is the intention of the parties that the general release, the waiver of unknown claims and the covenant not to sue above shall otherwise remain effective to release any and all other claims.
15.    Modification; Counterparts; Facsimile Signatures:  It is expressly agreed that this Agreement may not be altered, amended, modified, or otherwise changed in any respect except by another written agreement that specifically refers to this Agreement, executed by authorized representatives of each of the parties to this Agreement.  This Agreement may be executed in any number of counterparts, each of which shall constitute an original and all of which together shall constitute one and the same instrument.  Execution of a facsimile copy shall have the same force and effect as execution of an original and a copy of a signature will be equally admissible in any legal proceeding as an original.
16.    Time To Review Agreement; Right to Revoke; Knowing and Voluntary Agreement; Expiration of Offer:  You understand that you may take up to twenty-one (21) days to review this Agreement and, by signing below, affirm that you were advised to consult with an attorney prior to signing this Agreement.  You also understand you may revoke this Agreement within 

seven (7) days of signing this document and that the separation benefits to be provided to you pursuant to Section 3 will be provided only at the end of that seven (7) day revocation period without revocation by you. By signing this Agreement, you knowingly and voluntarily agree to all the terms set forth in this Agreement and further acknowledge that you are executing this Agreement voluntarily, free of any duress or coercion. If not accepted within the review period set forth in this section, this offer of benefits automatically expires.
17.    Effective Date:  This Agreement is effective on the eighth (8th) day after you sign it and without revocation by you as provided in Section 16 (the “Effective Date”).
18.    Governing Law:  This Agreement shall be governed by and construed in accordance with the laws of the State of California. 
If you agree to abide by the terms outlined in this Agreement, please sign this letter below and return it to me.  I wish you the best in your future endeavors.

Sincerely,

Rambus Inc.
