 EXHIBIT A 

MASTER TERMS AND CONDITIONS FOR CAPPED CALL TRANSACTIONS 

BETWEEN GOLDMAN, SACHS & CO. AND EQUINIX, INC. 

The purpose of this Master Terms and Conditions for Capped Call Transactions (this “Master Confirmation”), dated as of
June 9, 2009, is to set forth certain terms and conditions for capped call transactions to be entered into between Goldman, Sachs & Co. (“Dealer”) and Equinix, Inc. (“Counterparty”). Each such
transaction (a “Transaction”) entered into between Dealer and Counterparty that is to be subject to this Master Confirmation shall be evidenced by a written confirmation substantially in the form of Exhibit A hereto, with such
modifications thereto as to which Counterparty and Dealer mutually agree (a “Confirmation”). This Master Confirmation and each Confirmation together constitute a “Confirmation” as referred to in the Agreement specified
below. 
 This Master Confirmation and a Confirmation evidence a complete binding agreement between Dealer and Counterparty as to the terms
of the Transaction to which this Master Confirmation and such Confirmation relates. This Master Confirmation and each Confirmation hereunder shall supplement, form a part of, and be subject to an agreement in the form of the ISDA 2002 Master
Agreement as if Dealer and Counterparty had executed an agreement in such form on the Trade Date of the first such Transaction (but without any Schedule except for the election of the laws of the State of New York as the governing law) between
Dealer and Counterparty, and such agreement shall be considered the “Agreement” hereunder. 
 The definitions and
provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Definitions”) as published by ISDA are incorporated into this Master Confirmation. For the purposes of the Definitions, each reference herein or in any
Confirmation hereunder to a Unit (including a Designated Repurchase Unit) shall be deemed to be a reference to a Call Option or an Option, as context requires. 

THIS MASTER CONFIRMATION WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO CHOICE
OF LAW DOCTRINE. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN CONNECTION WITH ALL MATTERS RELATING HERETO AND
WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS. 
 The Transactions under
this Master Confirmation 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 under this Master Confirmation and the Agreement shall not be considered Transactions under, or otherwise governed by, such existing or deemed ISDA Master Agreement. 

1. In the event of any inconsistency between this Master Confirmation, on the one hand, and the Definitions or the Agreement, on the other
hand, this Master Confirmation will control for the purpose of the Transaction to which a Confirmation relates. In the event of any inconsistency between the Definitions, the Agreement and this Master Confirmation, on the one hand, and a
Confirmation, on the other hand, the Confirmation will govern. With respect to a Transaction, capitalized terms used herein that are not otherwise defined shall have the meaning assigned to them in the Confirmation relating to such Transaction. 

2. Each party will make each payment specified in this Master Confirmation or a Confirmation as being payable by such party, not later than
the due date for value on that date in the place of the account specified below or otherwise specified in writing, in freely transferable funds and in a manner customary for payments in the required currency. 

 3. Confirmations and General Terms: 

This Master Confirmation and the Agreement, together with the Confirmation relating to a Transaction, shall constitute the written agreement
between Counterparty and Dealer with respect to such Transaction.

subject to “Notice of Exercise” below; provided that, if Counterparty has elected the exchange in lieu of conversion option with respect to any Relevant Convertible Notes pursuant to the Exchange in Lieu of Conversion Provision, the

under “Required Exercise on Conversion Dates”.

  
 A-3 

			
		
	Notice of Exercise:	  	With respect to any Designated Repurchase Units, not applicable. With respect to all other Units, notwithstanding anything to the contrary in the Definitions, in order to exercise any Exercisable Units, Counterparty must notify

	Market Disruption Event:	  	Section 6.3(a) of the Definitions is hereby replaced in its entirety by the following:
		
		  	“‘Market Disruption Event’ means the occurrence or existence prior to 1:00 p.m. on any Scheduled Valid Day for the Shares of an aggregate one half-hour period, of any suspension or limitation imposed on trading (by
reason of movements in price exceeding limits permitted by the Exchange or otherwise) in the Shares or in any options, contracts or future contracts relating to the Shares.”

 5. Settlement Terms: 

 

			
	Settlement Method:	  	Net Share Settlement
		
	Net Share Settlement:	  	Seller will deliver to Counterparty, on the relevant Settlement Date, a number of Shares equal to the Net Shares in respect of any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder. In no event
will the Net Shares be less than zero.
		
		  	Seller will deliver cash in lieu of any fractional Shares to be delivered with respect to any Net Shares valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
		
	Net Shares:	  	In respect of any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder, a number of Shares equal to the Applicable Percentage multiplied by the lesser of:
		
		  	(i) (A) the sum of the quotients, for each Valid Day during the Settlement Averaging Period, of (x) the Unit Entitlement on such Valid Day, multiplied by (y) (1) the amount by which the Cap Price exceeds the Strike Price, if
the Relevant Price on such Valid Day is equal to or greater than the Cap Price, (2) the amount by which the Relevant Price exceeds the Strike Price, if such Relevant Price is greater than the Strike Price but less than the Cap Price or (3) zero, if
such Relevant Price is less than or equal to the Strike Price, divided by (z) such Relevant Price, divided by (B) the number of Valid Days in the Settlement Averaging Period (provided that, if such exercise relates to the
conversion of Relevant Convertible Notes in connection with which holders thereof are entitled to receive additional Shares and/or cash pursuant to the adjustments to the “Conversion Rate” (as defined in
the

  
 A-4 

			
		  	Indenture) set forth in the Make Whole Provision, then, notwithstanding the foregoing, the Net Shares shall include the Applicable Percentage of such additional Shares and/or cash, except that the Net Shares shall be capped so that
the value of the Net Shares per Exercisable Unit or Designated Repurchase Unit (with the value of any Shares included in the Net Shares determined by the Calculation Agent using the Relevant Price on the last Valid Day of the Settlement Averaging
Period) does not exceed the amount as determined by the Calculation Agent that would be payable by Dealer pursuant to Section 6 of the Agreement per Exercisable Unit or Designated Repurchase Unit if such Conversion Date were an Early Termination
Date resulting from an Additional Termination Event with respect to which the Transaction (except that, for purposes of determining such amount (x) the Number of Units (or the Number of Designated Repurchase Units, as the case may be) shall be
deemed to be equal to the relevant number of Exercisable Units (or the Number of Designated Repurchase Units, as the case may be) exercised or deemed exercised and (y) the Make Whole Provision shall be disregarded) was the sole Affected Transaction
and Counterparty was the sole Affected Party (determined without regard to Section 11(b) of this Confirmation) (this proviso, the “Limited Make Whole Provision”)) and
		
		  	(ii) the Applicable Limit divided by the Obligation Value Price;
		
		  	provided that clause (ii) shall not apply (x) if the applicable “Specified Cash Amount” (as defined in the Indenture) for the related Relevant Convertible Note is USD1,000 or (y) in respect of any Designated
Repurchase Units.
		
	Applicable Limit:	  	In respect of any Exercisable Unit exercised or deemed exercised hereunder, an amount in USD equal to the excess, if any, of (i) the aggregate of (A) the amount of cash, if any, delivered to the holder of the related Convertible
Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to such holder upon such conversion multiplied by the Obligation Value Price over (ii) USD1,000.
		
	Obligation Value Price:	  	The opening price as displayed under the heading “Op” on Bloomberg page EQIX.UQ <Equity> (or any successor thereto) on the Settlement Date.
		
	Valid Day:	  	Any day on which (i) there is no Market Disruption Event and (ii) The NASDAQ Global Select Market or, if the Shares are not quoted on The NASDAQ Global Select Market, the principal U.S. national or regional securities exchange on
which the Shares are listed, opens for trading during its regular trading session.
		
	Scheduled Valid Day:	  	A day that is scheduled to be a Valid Day.

Valid Day; or, if such price is not available, the Relevant Price means the market value per Share on such Valid Day as determined by the Calculation Agent.
		
	Settlement Averaging Period:	  	For any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder, the 25 consecutive Valid Days commencing on, and including, the 27th Scheduled Valid Day immediately preceding the Expiration
Date.
		
	Settlement Date:	  	For any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder, the third Scheduled Valid Day immediately following the final Valid Day of the Settlement Averaging Period.
		
	Settlement Currency:	  	USD
		
	Other Applicable Provisions:	  	To the extent Seller is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9, 9.10, 9.11, 9.12 and 10.5 of the Definitions will be applicable as if Physical Settlement were applicable to the
Transaction; provided that the Representation and Agreement contained in Section 9.11 of the 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. In addition, notwithstanding anything to the contrary in the Definitions, Seller may, in whole or in part, deliver any Shares hereunder in
certificated form representing the Net Shares to Counterparty in lieu of delivery through the Clearance System.

 6. Adjustments: 

 

			
	Potential Adjustment Events:	  	Notwithstanding Section 11.2(e) of the Definitions, a “Potential Adjustment Event” means the occurrence of any event or condition set forth in the Dilution Provision of the Indenture.
		
	Method of Adjustment:	  	Notwithstanding Section 11.2(c) of the Definitions, upon the occurrence of any event or condition set forth in the Dilution Provision of the Indenture, (i) the Calculation Agent shall make the corresponding adjustment in respect of
one or both of the Strike Price and the Unit Entitlement to the extent an analogous adjustment is made under the Indenture and (ii) solely with respect to any Units other than any Designated Repurchase Units, the Calculation Agent may, in its
reasonable discretion, except in the case of any event covered by the Stock Split Provision, make any adjustment consistent with the Calculation Agent Adjustment set forth in Section 11.2(c) (as modified by Section 15(i) and Section 15(ii) hereof)
of the Definitions to the Cap Price for such Units to preserve the fair value of the Transaction to Dealer after

  
 A-6 

			
		  	taking into account such Potential Adjustment Event; provided that in no event shall the Cap Price for such Units be less than the Strike Price. For the avoidance of doubt, the parties hereto agree and acknowledge that the
Cap Price for any Units other than Designated Repurchase Units following an adjustment pursuant to the immediately preceding sentence may be different than the Cap Price for any Designated Repurchase Units at such time.
		
	Stock Split Provision:	  	As set forth in the Confirmation for such Transaction

 7. Extraordinary Events: 

 

			
	Merger Events:	  	Applicable. Notwithstanding Section 12.1(b) of the Definitions, a “Merger Event” means the occurrence of any event or condition set forth in the Merger Provision of the Indenture.
		
		  	Promptly following the public announcement of any Merger Event or any public filing with respect to any Merger Event, Counterparty shall notify the Calculation Agent of such Merger Event; and once the adjustments to be made to the
terms of the Indenture and the Convertible Notes in respect of such Merger Event have been determined, Counterparty shall promptly notify the Calculation Agent in writing of the details of such adjustments.
		
	Notice of Merger Consideration:	  	Upon the occurrence of a Merger Event that causes the Shares to be converted into or exchanged for more than a single type of consideration (determined based in part upon any form of election of the holders of Shares), Counterparty
shall promptly (but in any event prior to the effective time of the Merger Event) notify the Calculation Agent of the types and amounts of consideration elected by a majority of the holders of Shares in any Merger Event who affirmatively make such
an election.
		
	Consequences of Merger Events:	  	Notwithstanding Section 12.2 of the Definitions, upon the occurrence of a Merger Event, (i) the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture to any one or more of the
nature of the Shares, the Strike Price and the Unit Entitlement to the extent an analogous adjustment is made under the Indenture and (ii) the Calculation Agent may, in its reasonable discretion, make any adjustment consistent with the Modified
Calculation Agent Adjustment set forth in Section 12.2(e) of the Definitions to the Cap Price provided that (A) such adjustment shall be made without regard to any adjustment to the Unit Entitlement for the issuance of additional shares as
set forth in the Excluded Provisions of the Indenture; (B) if such adjustment would (but for this clause (B)) result in the Shares including (or, at the option of a holder of Shares, may include) shares (or depositary receipts with respect to
shares) of an entity or person not organized under the laws of the United States, any State thereof or the District of Columbia and the Calculation Agent determines that (x) treating such Shares as Reference Property (as such term is defined in the
Indenture)

  
 A-7 

			
		  	will have a material adverse effect on Dealer’s rights or obligations in respect of the Transaction, on its Hedging Activities in respect of the Transaction or on the costs (including, without limitation, due to any increase in
tax liability, decrease in tax benefit or other adverse effect on its tax position) of engaging in any of the foregoing and (y) Dealer cannot promptly avoid the occurrence of each such material adverse effect by (I) transferring or assigning its
rights and obligations under the relevant Transaction pursuant to Section 11(d) of this Master Confirmation to an affiliate of Dealer that regularly engages in transactions similar to the Transaction or (II) amending the terms of this Master
Confirmation or the Confirmation (whether because amendments would not avoid such occurrence or because Counterparty fails to agree promptly to such amendments), no such adjustment shall be made and Cancellation and Payment (Calculation Agent
Determination) shall apply; and (C) in no event shall the Cap Price be less than the Strike Price. For the avoidance of doubt, adjustments shall be made pursuant to the provisions of subparagraphs (i) and (ii) above regardless of whether any Merger
Event gives rise to an Early Conversion.
		
	Dilution Provision:	  	As set forth in the Confirmation for such Transaction
		
	Merger Provision:	  	As set forth in the Confirmation for such Transaction
		
	Nationalization, Insolvency or Delisting:	  	Cancellation and Payment (Calculation Agent Determination). In addition to the provisions of Section 12.6(a)(iii) of the Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares
are not immediately re-listed or re-traded on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed or re-traded on any such
exchange, such exchange shall thereafter be deemed to be the Exchange.

 11. Miscellaneous: 

(a) [Reserved] 
 (b)
Alternative Calculations and Dealer Payment on Early Termination and on Certain Extraordinary Events. If Dealer owes Counterparty any amount in connection with a Transaction hereunder pursuant to Section 12.7 or 12.9 of the Definitions
(except in the case of an Extraordinary Event in which the consideration or proceeds to be paid to holders of Shares as a result of such event consists solely of cash) or pursuant to Section 6(d)(ii) of the Agreement (except in the case of 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 (x) Event of Default of the type described in Section 5(a)(iii), (v), (vi) or
(vii) of the Agreement or (y) a Termination Event of the type described in Section 5(b)(i), (ii), (iii), (iv), or (v) of the Agreement or under “Termination upon Early Conversion” below that in the case of either
(x) or (y) resulted from an event or events outside Counterparty’s control) (a “Dealer Payment Obligation”), Counterparty shall have the right, in its sole discretion, to require Dealer to satisfy any such Dealer
Payment Obligation by delivery of Termination Delivery Units (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, between the hours of 9:00 a.m. and 4:00 p.m. New York time on
the Merger Date, the Announcement Date (in the case of a Nationalization or Insolvency), or the Early Termination Date or other date of cancellation or termination, as applicable (“Notice of Dealer Termination Delivery”);
provided that Counterparty shall not have the right, notwithstanding any notice to the contrary, to require Dealer to satisfy the Dealer Payment Obligation by delivering Termination Delivery Units unless on the date of any such notice,
Counterparty represents to Dealer that, as of such date, it is not aware of any material non-public information regarding Counterparty or the Shares. Within a commercially reasonable period of time following receipt of a Notice of Dealer
Termination Delivery, Dealer shall deliver to Counterparty a number of Termination Delivery Units having a cash value equal to the amount of such Dealer Payment Obligation (such number of Termination Delivery Units to be delivered to be determined
by the Calculation Agent as the number of whole Termination Delivery Units that could be purchased over a commercially reasonable period of time with the cash equivalent of the Dealer Payment Obligation). 

“Termination Delivery Unit” means (i) in the case of a Termination Event, an Event of Default or an Extraordinary Event
(other than an Insolvency, Nationalization or Merger Event), one Share or (ii) in the case of an Insolvency, Nationalization or Merger Event, a unit consisting of the number or amount of each type of property received by a holder of one Share
(without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Insolvency, Nationalization or Merger Event. If a Termination Delivery Unit consists of property other than cash or
New Shares and Counterparty provides irrevocable written notice to the Calculation Agent on or prior to the Closing Date that it elects to have Dealer deliver cash, New Shares or a combination thereof (in such proportion as Counterparty designates)
in lieu of such other property, the Calculation Agent will replace such property with cash, New Shares or a combination thereof as components of a Termination Delivery Unit in such amounts, as determined by the Calculation Agent in its discretion by
commercially reasonable means, as shall have a value equal to the value of the property so replaced. If such Insolvency, Nationalization 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. 
 If the provisions of this paragraph (b) are applicable, the provisions of Sections
9.1(c), 9.8, 9.9, 9.10, 9.11, 9.12 and 10.5 of the Definitions will be applicable as if “Physical Settlement” applied to the Transaction, except that all references to “Shares” shall be read as references to “Termination
Delivery Units”; provided that the Representation and Agreement contained in Section 9.11 of the Definitions shall be modified by excluding any representations therein relating to restrictions, obligations, limitations or
requirements under applicable securities laws as a result of the fact that Buyer is the issuer of any Termination Delivery Units (or any part thereof). Notwithstanding anything to the contrary in the Definitions, Dealer may, in whole or in part,
deliver securities comprising Termination Delivery Units in certificated form to Counterparty in lieu of delivery through the Clearance System. 

(c) No Set-Off. Obligations under a Transaction hereunder shall not be set off against any other obligations of the parties, whether
arising under the Agreement, this Master Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other obligations of the parties shall 

  
 A-11 

 
be set off against obligations under a Transaction hereunder, whether arising under the Agreement, this Master Confirmation, under any other agreement between the parties hereto, by operation of
law or otherwise, and each party hereby waives any such right of setoff. 
 (d) Transfer or Assignment. Dealer may transfer or assign
all or any part of its rights or obligations under any Transaction only with the prior written consent of Counterparty; provided that, on ten business days’ prior written notice to Counterparty, Dealer may transfer or assign without any
consent of Counterparty its rights and obligations hereunder, in whole or in part, to any of its Affiliates, provided further that (A) such Affiliate is of credit quality equivalent to Dealer at the time hereof or its obligations
are guaranteed by The Goldman Sachs Group, Inc., (B) such transfer or assignment shall not have a material adverse tax or regulatory consequence to Counterparty, (C) an Event of Default, Potential Event of Default, or Termination Event
will not occur as a result of such transfer and assignment and (D) Dealer shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Counterparty in connection with such transfer or assignment.
If, on the advice of outside tax counsel, Counterparty reasonably determines that there is more than a de minimis possibility that such transfer or assignment would be treated as a termination or “leg out” of an integrated
transaction consisting of a Unit and a Convertible Note for U.S. federal income tax purposes, such transfer or assignment shall be deemed to be a material adverse tax consequence to Counterparty. If, as determined in Dealer’s reasonable
judgment, (a) at any time an Excess Ownership Position (as defined below) exists, and (b) Dealer is unable, after commercially reasonable efforts, to effect a transfer or assignment on pricing and terms and within a time period reasonably
acceptable to it of all or a portion of one or more Transactions pursuant to the preceding paragraph such that an Excess Ownership Position no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to
a portion (the “Terminated Portion”) of any Transaction(s), such that an Excess Ownership Position no longer exists following such partial termination. In the event that Dealer so designates an Early Termination Date with respect to
a portion of any Transaction(s), a payment or delivery shall be made pursuant to Section 6 of the Agreement and Section 11(b) of this Master Confirmation as if (i) an Early Termination Date had been designated in respect of a
Transaction having terms identical to the Terminated Portion of the Transaction(s), (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction(s) shall be the only
Terminated Transaction. Dealer agrees that it shall use commercially reasonable efforts, in consultation with counsel as to legal and regulatory issues, to hedge its exposure to the Transaction and to manage its other positions through the use of
cash-settled swaps or other derivative instruments to the extent necessary to avoid the occurrence of an Excess Ownership Position. The “Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the
numerator of which is the number of Shares that Dealer and any of its affiliates subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act and all persons who may form a
“group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Dealer (collectively, “Dealer Group”) “beneficially own” (within the meaning of Section 13 of the Exchange Act) without
duplication on such day and (B) the denominator of which is the number of Shares outstanding on such day. Counterparty may not transfer or assign its rights and obligations hereunder without the prior consent of Dealer, which consent shall not
be unreasonably withheld. For the avoidance of doubt, Dealer may condition its consent on any of the following, without limitation: (i) the receipt by Dealer of opinions and documents reasonably satisfactory to Dealer in connection with such
transfer or assignment, (ii) such transfer or assignment being effected on terms reasonably satisfactory to Dealer with respect to any legal and regulatory requirements relevant to Dealer, and (iii) Equinix, Inc. (or any successor obligor
under the Convertible Notes) continuing to be obligated with respect to “Notice of Merger Consideration”, “Repurchase Notices”, “Registration” and “Conversion Rate Adjustments” following such transfer or
assignment, (iv) such assignment being made to a U.S. person (as defined in the Internal Revenue Code of 1986, as amended), (v) Dealer not, as a result of such assignment, being required to pay the transferee on any payment date an amount
under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment, (vi) no Event of Default, Potential Event of Default or
Termination Event occurring as a result of such assignment, (vii) if Dealer reasonably requests, the transferee agreeing not to hedge its exposure to the Transaction, or to hedge such exposure only pursuant to an effective registration of
Equinix, Inc. (or any successor obligor under the Convertible Notes) or otherwise in compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable
securities laws, (viii) without limiting the generality of clause (v), Counterparty causing the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to
determine that results described in clauses (v) and (vi) will not occur upon or after such 

  
 A-12 

 
transfer and assignment, and (ix) Counterparty being responsible for Dealer’s reasonable out-of-pocket costs and expenses, including reasonable fees of counsel, incurred in connection
with such transfer and assignment. “Excess Ownership Position” means (1) the Equity Percentage exceeds 8.0%, (2) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that
of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a “Dealer Person”) under Section 203 of the Delaware General Corporation Law (the “DGCL Takeover Statute”) or other federal, state or local
laws, regulations or regulatory orders applicable to ownership of Shares (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership, or
could be reasonably viewed as meeting any of the foregoing, in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting, registration, filing or notification obligations or other requirements (including
obtaining prior approval by a state or federal regulator) of a Dealer Person under Applicable Laws (including, without limitation, “interested shareholder” or “acquiring Person” status under the DGCL Takeover Statute) and with
respect to which such requirements have not been met or the relevant approval has not been received minus (y) 1% of the number of Shares outstanding on the date of determination, (3) solely with respect to any Designated Repurchase
Units, any Dealer Person under the organizational documents of Counterparty owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership, or could be reasonably viewed as
meeting any of the foregoing, in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting, registration, filing or notification obligations or other requirements (including obtaining prior approval by a
state or federal regulator) of a Dealer Person, or would result in an adverse effect on a Dealer Person, in each case, under the organizational documents of Counterparty and with respect to which such requirements have not been met or the relevant
approval has not been received minus (y) 1% of the number of Shares outstanding on the date of determination or (4) the Units Equity Percentage (as defined below) exceeds 9%. 

(e) Additional Termination Events. For any Transaction, the occurrence of (A) an “Event of Default” (as defined in the
Indenture for such Transaction) with respect to Counterparty under the terms of the Convertible Notes for such Transaction that results in an acceleration of such Convertible Notes pursuant to the terms of such Indenture, (B) an Amendment Event
or (C) a Repayment Event shall be an Additional Termination Event with respect to which such Transaction is the sole Affected Transaction and Counterparty shall be the sole Affected Party, and Seller shall be the party entitled to designate an
Early Termination Date pursuant to Section 6(b) of the Agreement; provided that, in the case of a Repayment Event, the Transaction(s) shall be subject to termination only in respect of the portion of the Transaction(s) corresponding to the
number of Convertible Notes that cease to be outstanding in connection with or as a result of such Repayment Event. 

“Amendment Event” means, for any Transaction, that, without the prior written consent of Dealer, Counterparty
amends, modifies, supplements or obtains a waiver of any term of the Indenture for such Transaction or the Convertible Notes for such Transaction governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption
right of Counterparty, any term relating to exchange of the Convertible Notes for such Transaction (including changes to the conversion rate, the conversion price, conversion settlement dates or conversion conditions), or any term that would require
consent of the holders of not less than 100% of the principal amount of the Convertible Notes for such Transaction to amend, in each case where Dealer reasonably determines that such event will have a material adverse effect on Dealer’s rights
or obligations in respect of such Transaction, on its Hedging Activities in respect of such Transaction or on the costs (including, without limitation, due to any increase in tax liability, decrease in tax benefit or other adverse effect on its tax
position) of engaging in any of the foregoing. 
 “Repayment Event” means that, for any Transaction (I) any
Convertible Notes for such Transaction are repurchased (whether in connection with or as a result of a fundamental change, howsoever defined, or for any other reason) by Counterparty or any of its subsidiaries, (II) any Convertible Notes for such
Transaction are delivered to Counterparty or any of its subsidiaries in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (III) any principal of any of the Convertible Notes for such
Transaction is repaid prior to the final maturity date of such Convertible Notes (whether following acceleration of such Convertible Notes or otherwise), (IV) any Convertible Notes for such Transaction are

  
 A-13 

 
exchanged by or for the benefit of the holders thereof for any other securities (including, for the avoidance of doubt, Shares) of Counterparty or any of its affiliates (or any other property, or
any combination thereof) pursuant to any exchange offer or similar transaction or (V) any combination of (I)-(IV); provided that (x) any conversion of the Convertible Notes for such Transaction by holders thereof (including conversions for
which the Counterparty has elected the exchange in lieu of conversion option pursuant to the Exchange in Lieu of Conversion Provision) pursuant to the terms of the Indenture for such Transaction at the “Conversion Rate” set forth in such
Indenture (determined without regard to any provision or term of the Indenture that allows Counterparty to voluntarily increase such “Conversion Rate”) shall not be a Repayment Event and (y) any Excluded Repayment Event shall not be a
Repayment Event. 
 (f) Termination upon Early Conversion. Notwithstanding anything to the contrary in this Master Confirmation, upon
the occurrence of a Conversion Date with respect to an Early Conversion other than an Early Conversion that has been validly retracted pursuant to the Retraction Provision by the holder of the related Convertible Note: 

(A) Counterparty shall within one Scheduled Valid Day of the Conversion Date (or, if applicable, the final day of the “Conversion
Retraction Period” (as defined in the Indenture)) for such Early Conversion provide written notice (an “Excluded Conversion Notice”) to Dealer specifying the number of Relevant Convertible Notes converted on such Conversion
Date and not validly retracted; 
 (B) such Early Conversion shall constitute an Additional Termination Event hereunder with respect to the
number of Units relating to the number of Relevant Convertible Notes surrendered for conversion in connection with such Early Conversion (the “Affected Number of Units”), in which case (x) the sole Affected Transaction shall
consist of a transaction identical to the Transaction except that Number of Units for such Affected Transaction shall equal the Affected Number of Units and Counterparty shall be deemed the sole Affected Party and (y) the Transaction shall
remain in full force and effect, except that the Number of Units subject to the Transaction immediately prior to the Conversion Date for such Early Conversion shall as of such Conversion Date be reduced by the Affected Number of Units; 

(C) notwithstanding anything to the contrary in the Agreement, Dealer shall designate an Early Termination Date in respect of such Affected
Transaction, which shall be no earlier than one Scheduled Valid Day following the effective date of delivery of an Excluded Conversion Notice for the related Early Conversion and no later than five Scheduled Valid Days following such effective date;
and 
 (D) for the avoidance of doubt, in determining the amount payable in respect of such Affected Transaction pursuant to Section 6
of the Agreement (which, for the avoidance of doubt, shall take into account the Limited Make Whole Provision, if such Early Conversion relates to the conversion of Relevant Convertible Notes in connection with which holders thereof are entitled to
receive additional Shares and/or cash pursuant to the adjustments to the “Conversion Rate” (as defined in the Indenture) set forth in the Make Whole Provision), Dealer shall assume that (x) the relevant Early Conversion and any
adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (y) no adjustments to the Conversion Rate have occurred pursuant to the Excluded Provisions and (z) the
corresponding Convertible Notes remain outstanding. 
 For the avoidance of doubt, no event that constitutes a Repayment Event or an
Excluded Repayment Event shall be an Early Conversion. 
 (g) Status of Claims in Bankruptcy. Dealer acknowledges and agrees that
this Master Confirmation, together with any Confirmation, is not intended to convey to Dealer rights with respect to any Transaction that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of

  
 A-14 

 
Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and
agreements with respect to any Transaction; and provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transactions. 

(h) No Collateral Delivery by Counterparty. Notwithstanding any provision of this Master Confirmation, any Confirmation or the
Agreement, or any other agreement between the parties, to the contrary, the obligations of Counterparty under the Transactions are not secured by any collateral. Without limiting the generality of the foregoing, if this Master Confirmation, the
Agreement or any other agreement between the parties includes an ISDA Credit Support Annex or other agreement pursuant to which Counterparty collateralizes obligations to Dealer, then the obligations of Counterparty hereunder will not be considered
to be obligations under such Credit Support Annex or other agreement pursuant to which Counterparty collateralizes obligations to Dealer, and any Transactions hereunder shall be disregarded for purposes of calculating any Exposure, Market Value or
similar term thereunder. 
 (i) Assignment of Share Delivery to Affiliates 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 the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

 (j) Severability; Illegality. If compliance by either party with any provision of a Transaction would be unenforceable or illegal,
(i) the parties shall negotiate in good faith to resolve such unenforceability or illegality in a manner that preserves the economic benefits of the transactions contemplated hereby and (ii) the other provisions of the Transaction shall
not be invalidated, but shall remain in full force and effect. 
 (k) Waiver of Trial by Jury. EACH OF COUNTERPARTY AND DEALER HEREBY
IRREVOCABLY WAIVES (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS) ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF
OR RELATING TO THIS TRANSACTION OR THE ACTIONS OF DEALER OR ITS AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF. 
 (l)
Confidentiality. Notwithstanding any provision in this Master Confirmation, any Confirmation or the Agreement, in connection with Section 1.6011-4 of the Treasury Regulations, the parties hereby agree that each party (and each employee,
representative, or other agent of such party) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of the Transaction and all materials of any kind (including opinions or other tax
analyses) that are provided to such party relating to such U.S. tax treatment and U.S. tax structure, other than any information for which nondisclosure is reasonably necessary in order to comply with applicable securities laws. 

(m) Securities Contract; Swap Agreement. The parties hereto agree and acknowledge that Dealer is a “financial institution,”
“swap participant” and “financial participant” within the meaning of Sections 101(22), 101(53C) and 101(22A) of Title 11 of the United States Code (the “Bankruptcy Code”). The parties hereto further agree and
acknowledge (A) that this Confirmation is (i) a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is
a “termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “settlement payment” or a “transfer” within the meaning of
Section 546 of the Bankruptcy Code, and (ii) a “swap agreement,” as such term is defined in Section 101(53B) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a
“termination value,” a “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “transfer” within the meaning of Section 546 of the Bankruptcy
Code, and (B) that Dealer is entitled to the protections afforded by, among other sections, Section 362(b)(6), 362(b)(17), 362(b)(27), 362(o), 546(e), 546(g), 546(j), 548(d)(2), 555, 560 and 561 of the Bankruptcy Code. 

  
 A-15 

 (n) Postponement of Settlement. Dealer may postpone any Potential Exercise Date or any
other date of valuation or delivery by Seller or add additional Settlement Dates or any other date of valuation or delivery by Seller, with respect to some or all of the relevant Units (in which event the Calculation Agent shall make appropriate
adjustments to the number of Net Shares), by at most twenty Scheduled Trading Days, if Dealer reasonably determines that such extension is necessary or appropriate to preserve Dealer’s hedging activity hereunder in light of existing liquidity
conditions (but only if there is a material decrease in liquidity relative to Dealer’s expectations on the Trade Date) or to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity
hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal and regulatory requirements or self-regulatory requirements, or with related policies and procedures
applicable to Dealer. In connection with any Settlement Date that is postponed pursuant to the immediately preceding sentence, if Shares are to be delivered by Dealer to Counterparty on such postponed Settlement Date and the record date for any
dividend or distribution on the Shares occurs during the period from, and including, the original Settlement Date to, but excluding, such postponed Settlement Date, then on such postponed Settlement Date, in addition to delivering such Shares,
Dealer shall pay or deliver, as the case may be, to Counterparty, the per Share amount of such dividend or distribution multiplied by the number of Shares to be delivered. 

(o) Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory requirements, including any
requirements relating to Dealer’s hedging activities hereunder, Dealer reasonably determines that it would not be practicable or appropriate to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on a
Settlement Date for a Transaction, Dealer may, by notice to the Counterparty prior to any Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement
Date”) or at two or more times on the Nominal Settlement Date as follows: 
 (i) in such notice, Dealer will specify
to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date, but not prior to the beginning of the Settlement Averaging Period) or delivery times and how it will allocate the Shares it is
required to deliver hereunder in connection with any Net Share Settlement among the Staggered Settlement Dates or delivery times; and 

(ii) the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates
and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date. 

(p) Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a
written notice of such repurchase (a “Repurchase Notice”) on such day if, following such repurchase, the Units Equity Percentage as determined on such day is (i) equal to or greater than 6.0% and (ii) greater by 0.5% or
more than the Units Equity Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater by 0.5% or more than the Units Equity Percentage as of the date hereof). The “Units
Equity Percentage” as of any day is the fraction the numerator of which is the aggregate of the Applicable Percentage of the sum of (x) the Number of Shares for all Transactions hereunder, and (y) the product of
(A) the Number of Designated Repurchase Units for all Transactions hereunder, and (B) the Unit Entitlement, and the denominator of which is the number of Shares outstanding on such day. Counterparty agrees to indemnify and hold
harmless Dealer and its Affiliates and their respective officers, directors and controlling persons (each, a “Section 16 Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging
activities as a consequence of becoming, or of the risk of becoming, subject to the reporting and profit disgorgement provisions of Section 16 of the Exchange Act, including without limitation, any forbearance from hedging activities or
cessation of hedging activities and any losses in connection therewith with respect to any Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, to which a Section 16
Indemnified Person may become subject, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph (p), and to reimburse, upon written request, each such
Section 16 Indemnified Person for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action,
proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Section 16 

  
 A-16 

 
Indemnified Person, such Section 16 Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of such Section 16 Indemnified Person, shall retain
counsel reasonably satisfactory to such Section 16 Indemnified Person to represent such Section 16 Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related
to such proceeding. Counterparty shall be relieved from liability to the extent that such Section 16 Indemnified Person fails to promptly notify Counterparty of any action commenced against it in respect of which indemnity may be sought
hereunder; provided that failure to notify Counterparty (i) shall not relieve Counterparty from any liability hereunder to the extent it is not materially prejudiced as a result thereof and (ii) shall not, in any event, relieve
Counterparty from any liability that it may have otherwise than on account of this paragraph (p). Counterparty shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Section 16 Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written
consent of each Section 16 Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Section 16 Indemnified Person is or could have been a party and indemnity could have been sought hereunder
by any such Section 16 Indemnified Person, unless such settlement includes an unconditional release of each such Section 16 Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably
satisfactory to each such Section 16 Indemnified Person. If the indemnification provided for in this paragraph (p) is unavailable to a Section 16 Indemnified Person or insufficient in respect of any losses, claims, damages or
liabilities referred to therein, then Counterparty, in lieu of indemnifying such Section 16 Indemnified Person thereunder, shall contribute to the amount paid or payable by such Section 16 Indemnified Person as a result of such losses,
claims, damages or liabilities. The remedies provided for in this paragraph (p) are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Section 16 Indemnified Person at law or in equity. The
indemnity and contribution agreements contained in this paragraph (p) shall remain operative and in full force and effect regardless of the termination of any Transaction. 

(q) Early Unwind. In the event the sale of Convertible Notes for any Transaction hereunder is not consummated pursuant to the
underwriting agreement (the “Underwriting Agreement”) dated June 9, 2009 between Counterparty and Citigroup Global Markets Inc. and J.P. Morgan Securities Inc. (the “Representatives”), as representatives of the
underwriters thereunder (the “Underwriters”) by the close of business in New York City on the Early Unwind Date set forth in the Confirmation for such Transaction, such Transaction shall automatically terminate on such Early Unwind
Date and (i) such Transaction and all of the respective rights and obligations of Dealer and Counterparty under such Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from
and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with such Transaction either prior to or after such Early Unwind Date;
provided that, if such failure is due to a breach or default on the part of Counterparty under the Underwriting Agreement, Counterparty shall assume, or reimburse the cost of, derivatives or other transactions entered into by Dealer or one or
more of its Affiliates in connection with hedging such Transaction. The amount paid by Counterparty shall be Dealer’s actual cost of such derivatives or other transactions as Dealer informs Counterparty and shall be paid in immediately
available funds on such Early Unwind Date or, at the election of Counterparty, in lieu of such payment Counterparty may deliver to Dealer, on such Early Unwind Date, Shares with a value equal to such amount, as determined by the Calculation Agent,
in which event the parties shall enter into customary and commercially reasonable documentation relating to the registered or exempt resale of such Shares; provided that in no event shall Counterparty be obligated to deliver in excess of
770,894 Shares. 
 (r) Registration. Counterparty hereby agrees that if any Shares (the “Hedge Shares”) acquired by
Dealer for the purpose of hedging its obligations pursuant to the Transaction, in Dealer’s reasonable judgment based on the advice of outside counsel, cannot be sold in the U.S. public market by Dealer without registration under the Securities
Act, Counterparty shall, at its election: (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act to cover the resale of such Hedge
Shares and (A) enter into an agreement, in form and substance reasonably satisfactory to Dealer and Counterparty, substantially in the form of an underwriting agreement for a registered secondary offering of a similar size, (B) provide
accountant’s “comfort” letters in customary form for registered offerings of equity securities, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Dealer,
(D) provide other customary opinions, certificates and closing 

  
 A-17 

 
documents customary in form for registered offerings of equity securities and (E) afford Dealer a reasonable opportunity to conduct a “due diligence” investigation with respect to
Counterparty customary in scope for underwritten offerings of equity securities; provided that if Dealer, in its reasonable judgment, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or
the procedures and documentation for the registered offering referred to above, then clause (ii) or (iii) of this paragraph (r) shall apply at the election of Counterparty; (ii) in order to allow Dealer to sell the Hedge Shares
in a private placement, enter into a private placement agreement substantially similar to private placement agreements customary for private placements of equity securities of a similar size, in form and substance reasonably satisfactory to Dealer
and Counterparty, including customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Hedge Shares from Dealer),
opinions and certificates and such other documentation as is customary for private placement agreements for private placements of a similar size, all reasonably acceptable to Dealer (in which case, the Calculation Agent shall make any adjustments to
the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement); or (iii) purchase the
Hedge Shares from Dealer at the price displayed under the heading “Bloomberg VWAP” on Bloomberg page EQIX.UQ <Equity> VAP (or successor thereto) in respect of the period from the scheduled opening time of the Exchange to the
Scheduled Closing Time of the Exchange on a relevant Exchange Business Day (or if such volume-weighted average price is unavailable, the market value of one Share on such Exchange Business Day, as determined by the Calculation Agent using a
volume-weighted method) on such Exchange Business Days, and in the amounts requested by Dealer. For the avoidance of doubt, unless Counterparty elects to repurchase the Hedge Shares pursuant to clause (iii) of this paragraph (r), nothing in
this Master Confirmation shall be interpreted as requiring Counterparty to repurchase the Hedge Shares or otherwise pay any amount of cash to Dealer pursuant to this paragraph (r) and under no circumstances shall Counterparty be required to
repurchase the Hedge Shares or otherwise pay any amount of cash to Dealer pursuant to this paragraph (r). This paragraph (r) shall survive the termination, expiration or early unwind of any Transaction for a period reasonably determined by
Dealer (which period shall end no later than the thirtieth consecutive Valid Day on which Counterparty has satisfied all of its obligations pursuant to this paragraph (r) and the agreements referred to herein). 

(s) Conversion Rate Adjustments. Counterparty shall provide to Dealer written notice (such notice, an “Conversion Rate
Adjustment Notice”) at least five Scheduled Trading Days prior to consummating or otherwise executing or engaging in any transaction or event other than a stock split, reverse stock split or stock dividend (an “Conversion Rate
Adjustment Event”) that would lead to a change in the “Conversion Rate” (as such term is defined in the Indenture), which Conversion Rate Adjustment Notice shall set forth the new, adjusted Conversion Rate after giving effect to
such Conversion Rate Adjustment Event (the “New Conversion Rate”). In connection with the delivery of any Conversion Rate Adjustment Notice to Dealer, Counterparty shall, concurrently with or prior to such delivery,
(x) publicly announce and disclose the Conversion Rate Adjustment Event or (y) represent and warrant that the information set forth in such Conversion Rate Adjustment Notice does not constitute material non-public information with respect
to Counterparty or the Shares. 
 (t) Counterparty’s Obligation to Pay Cancellation Amounts and Early Termination Amounts.
Dealer and Counterparty hereby agree that, notwithstanding anything to the contrary herein or in the Agreement, following Dealer’s receipt of the Premium for any Transaction from Counterparty on the Premium Payment Date for such Transaction, in
the event that (i) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to such Transaction and, as a result, Counterparty owes to Dealer an Early Termination Amount
or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Definitions, a Cancellation Amount, such amount shall be deemed to be zero. If Counterparty pays the Premium for any Transaction on the Premium
Payment Date for such Transaction, then under no circumstances shall Counterparty be required to pay any amount in addition to the Premium with respect to such Transaction, except in the case of a breach by Counterparty of a representation or
covenant hereunder. 
 (u) [Reserved] 

(v) Applicability of Indenture. For the avoidance of doubt, any adjustment, notice or other provision contained in this Master
Confirmation or any Confirmation hereunder related to or referencing the Indenture or the Convertible Notes shall continue to apply to the Units (including, for the avoidance of doubt, Designated Repurchase Units) irrespective of whether any
Convertible Notes remain outstanding. 

  
 A-18 

 (w) Other Adjustments Pursuant to the Definitions. Notwithstanding anything to the
contrary in this Master Confirmation, solely for the purpose of adjusting the Cap Price for any Designated Repurchase Units, the term “Potential Adjustment Event” shall have the meaning assigned to it in the Definitions (as amended by
Section 15(iii) hereof), and upon the occurrence of the declaration by Counterparty of the terms of any Potential Adjustment Event, as such term is defined in the Definitions, the Calculation Agent may, in its sole discretion, adjust the Cap
Price to preserve the fair value of the Designated Repurchase Units to Dealer; provided that in no event shall the Cap Price for such Designated Repurchase Units be less than the Strike Price. For the avoidance of doubt, the parties hereto
agree and acknowledge that the Cap Price for any Designated Repurchase Units following an adjustment pursuant to this Section 11(w) may be different than the Cap Price for any Units other than Designated Repurchase Units at such time.

 EXHIBIT A 

MASTER TERMS AND CONDITIONS FOR CAPPED CALL TRANSACTIONS 

BETWEEN DEUTSCHE BANK AG, LONDON BRANCH AND EQUINIX, INC. 

The purpose of this Master Terms and Conditions for Capped Call Transactions (this “Master Confirmation”), dated as of
June 9, 2009, is to set forth certain terms and conditions for capped call transactions to be entered into between Deutsche Bank AG, London Branch (“Dealer”) and Equinix, Inc. (“Counterparty”). Each such
transaction (a “Transaction”) entered into between Dealer and Counterparty that is to be subject to this Master Confirmation shall be evidenced by a written confirmation substantially in the form of Exhibit A hereto, with such
modifications thereto as to which Counterparty and Dealer mutually agree (a “Confirmation”). This Master Confirmation and each Confirmation together constitute a “Confirmation” as referred to in the Agreement specified
below. 
 DEUTSCHE BANK AG IS NOT REGISTERED AS A BROKER OR DEALER UNDER THE U.S. SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. DEUTSCHE
BANK SECURITIES INC. (“AGENT”) HAS ACTED SOLELY AS AGENT IN CONNECTION WITH ANY TRANSACTION HEREUNDER AND HAS NO OBLIGATION, BY WAY OF ISSUANCE, ENDORSEMENT, GUARANTEE OR OTHERWISE WITH RESPECT TO THE PERFORMANCE OF EITHER PARTY
UNDER THE TRANSACTION. DEUTSCHE BANK AG, LONDON BRANCH IS NOT A MEMBER OF THE SECURITIES INVESTOR PROTECTION CORPORATION (SIPC). 
 This
Master Confirmation and a Confirmation evidence a complete binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Master Confirmation and such Confirmation relates. This Master Confirmation and each
Confirmation hereunder shall supplement, form a part of, and be subject to an agreement in the form of the ISDA 2002 Master Agreement as if Dealer and Counterparty had executed an agreement in such form on the Trade Date of the first such
Transaction (but without any Schedule except for the election of the laws of the State of New York as the governing law) between Dealer and Counterparty, and such agreement shall be considered the “Agreement” hereunder. 

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Definitions”) as published by
ISDA are incorporated into this Master Confirmation. For the purposes of the Definitions, each reference herein or in any Confirmation hereunder to a Unit (including a Designated Repurchase Unit) shall be deemed to be a reference to a Call Option or
an Option, as context requires. 
 THIS MASTER CONFIRMATION WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK, WITHOUT REFERENCE TO CHOICE OF LAW DOCTRINE. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK IN
CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS. 

The Transactions under this Master Confirmation 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 under this Master Confirmation and the Agreement shall not be considered Transactions under, or
otherwise governed by, such existing or deemed ISDA Master Agreement.

	Automatic Exercise:	  	With respect to any Designated Repurchase Units, applicable as if “Cash Settlement” were applicable to such Units for purposes of Section 3.4 of the Definitions, and with respect to all other Units, as provided above under
“Required Exercise on Conversion Dates”.
		
	Notice of Exercise:	  	With respect to any Designated Repurchase Units, not applicable. With respect to all other Units, notwithstanding anything to the contrary in the Definitions, in order to exercise any Exercisable Units, Counterparty must notify

		  	“‘Market Disruption Event’ means the occurrence or existence prior to 1:00 p.m. on any Scheduled Valid Day for the Shares of an aggregate one half-hour period, of any suspension or limitation imposed on trading (by
reason of movements in price exceeding limits permitted by the Exchange or otherwise) in the Shares or in any options, contracts or future contracts relating to the Shares.”

 5. Settlement Terms: 

 

			
	Settlement Method:	  	Net Share Settlement
		
	Net Share Settlement:	  	Seller will deliver to Counterparty, on the relevant Settlement Date, a number of Shares equal to the Net Shares in respect of any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder. In no event
will the Net Shares be less than zero.
		
		  	Seller will deliver cash in lieu of any fractional Shares to be delivered with respect to any Net Shares valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.
		
	Net Shares:	  	In respect of any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder, a number of Shares equal to the Applicable Percentage multiplied by the lesser of:
		
		  	(i) (A) the sum of the quotients, for each Valid Day during the Settlement Averaging Period, of (x) the Unit Entitlement on such Valid Day, multiplied by (y) (1) the amount by which the

  
 A-4 

			
		  	Cap Price exceeds the Strike Price, if the Relevant Price on such Valid Day is equal to or greater than the Cap Price, (2) the amount by which the Relevant Price exceeds the Strike Price, if such Relevant Price is greater than the
Strike Price but less than the Cap Price or (3) zero, if such Relevant Price is less than or equal to the Strike Price, divided by (z) such Relevant Price, divided by (B) the number of Valid Days in the Settlement Averaging Period
(provided that, if such exercise relates to the conversion of Relevant Convertible Notes in connection with which holders thereof are entitled to receive additional Shares and/or cash pursuant to the adjustments to the “Conversion
Rate” (as defined in the Indenture) set forth in the Make Whole Provision, then, notwithstanding the foregoing, the Net Shares shall include the Applicable Percentage of such additional Shares and/or cash, except that the Net Shares shall be
capped so that the value of the Net Shares per Exercisable Unit or Designated Repurchase Unit (with the value of any Shares included in the Net Shares determined by the Calculation Agent using the Relevant Price on the last Valid Day of the
Settlement Averaging Period) does not exceed the amount as determined by the Calculation Agent that would be payable by Dealer pursuant to Section 6 of the Agreement per Exercisable Unit or Designated Repurchase Unit if such Conversion Date were an
Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction (except that, for purposes of determining such amount (x) the Number of Units (or the Number of Designated Repurchase Units, as the case may
be) shall be deemed to be equal to the relevant number of Exercisable Units (or the Number of Designated Repurchase Units, as the case may be) exercised or deemed exercised and (y) the Make Whole Provision shall be disregarded) was the sole Affected
Transaction and Counterparty was the sole Affected Party (determined without regard to Section 11(b) of this Confirmation) (this proviso, the “Limited Make Whole Provision”)) and
		
		  	(ii) the Applicable Limit divided by the Obligation Value Price;
		
		  	provided that clause (ii) shall not apply (x) if the applicable “Specified Cash Amount” (as defined in the Indenture) for the related Relevant Convertible Note is USD1,000 or (y) in respect of any Designated
Repurchase Units.
		
	Applicable Limit:	  	In respect of any Exercisable Unit exercised or deemed exercised hereunder, an amount in USD equal to the excess, if any, of (i) the aggregate of (A) the amount of cash, if any, delivered to the holder of the related Convertible
Note upon conversion of such Convertible Note and (B) the number of Shares, if any, delivered to such holder upon such conversion multiplied by the Obligation Value Price over (ii) USD1,000.

  
 A-5 

 
			
	Obligation Value Price:	  	The opening price as displayed under the heading “Op” on Bloomberg page EQIX.UQ <Equity> (or any successor thereto) on the Settlement Date.
		
	Valid Day:	  	Any day on which (i) there is no Market Disruption Event and (ii) The NASDAQ Global Select Market or, if the Shares are not quoted on The NASDAQ Global Select Market, the principal U.S. national or regional securities exchange on
which the Shares are listed, opens for trading during its regular trading session.
		
	Scheduled Valid Day:	  	A day that is scheduled to be a Valid Day.
		
	Relevant Price:	  	On any Valid Day, the per Share volume-weighted average price as displayed on Bloomberg (or any successor service) page EQIX.UQ <Equity> VAP in respect of the period from 9:30 a.m. to 4:00 p.m., New York City time, on such
Valid Day; or, if such price is not available, the Relevant Price means the market value per Share on such Valid Day as determined by the Calculation Agent.
		
	Settlement Averaging Period:	  	For any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder, the 25 consecutive Valid Days commencing on, and including, the 27th Scheduled Valid Day immediately preceding the Expiration
Date.
		
	Settlement Date:	  	For any Exercisable Unit or Designated Repurchase Unit exercised or deemed exercised hereunder, the third Scheduled Valid Day immediately following the final Valid Day of the Settlement Averaging Period.
		
	Settlement Currency:	  	USD
		
	Other Applicable Provisions:	  	To the extent Seller is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9, 9.10, 9.11, 9.12 and 10.5 of the Definitions will be applicable as if Physical Settlement were applicable to the
Transaction; provided that the Representation and Agreement contained in Section 9.11 of the 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. In addition, notwithstanding anything to the contrary in the Definitions, Seller may, in whole or in part, deliver any Shares hereunder in
certificated form representing the Net Shares to Counterparty in lieu of delivery through the Clearance System.

 6. Adjustments: 

 

			
	Potential Adjustment Events:	  	Notwithstanding Section 11.2(e) of the Definitions, a “Potential Adjustment Event” means the occurrence of any event or condition set forth in the Dilution Provision of the Indenture.

  
 A-6 

 
			
	Method of Adjustment:	  	Notwithstanding Section 11.2(c) of the Definitions, upon the occurrence of any event or condition set forth in the Dilution Provision of the Indenture, (i) the Calculation Agent shall make the corresponding adjustment in respect of
one or both of the Strike Price and the Unit Entitlement to the extent an analogous adjustment is made under the Indenture and (ii) solely with respect to any Units other than any Designated Repurchase Units, the Calculation Agent may, in its
reasonable discretion, except in the case of any event covered by the Stock Split Provision, make any adjustment consistent with the Calculation Agent Adjustment set forth in Section 11.2(c) (as modified by Section 15(i) and Section 15(ii) hereof)
of the Definitions to the Cap Price for such Units to preserve the fair value of the Transaction to Dealer after taking into account such Potential Adjustment Event; provided that in no event shall the Cap Price for such Units be less than
the Strike Price. For the avoidance of doubt, the parties hereto agree and acknowledge that the Cap Price for any Units other than Designated Repurchase Units following an adjustment pursuant to the immediately preceding sentence may be different
than the Cap Price for any Designated Repurchase Units at such time.
		
	Stock Split Provision:	  	As set forth in the Confirmation for such Transaction

 7. Extraordinary Events: 

 

			
	Merger Events:	  	Applicable. Notwithstanding Section 12.1(b) of the Definitions, a “Merger Event” means the occurrence of any event or condition set forth in the Merger Provision of the Indenture.
		
		  	Promptly following the public announcement of any Merger Event or any public filing with respect to any Merger Event, Counterparty shall notify the Calculation Agent of such Merger Event; and once the adjustments to be made to the
terms of the Indenture and the Convertible Notes in respect of such Merger Event have been determined, Counterparty shall promptly notify the Calculation Agent in writing of the details of such adjustments.
		
	Notice of Merger Consideration:	  	Upon the occurrence of a Merger Event that causes the Shares to be converted into or exchanged for more than a single type of consideration (determined based in part upon any form of election of the holders of Shares), Counterparty
shall promptly (but in any event prior to the effective time of the Merger Event) notify the Calculation Agent of the types and amounts of consideration elected by a majority of the holders of Shares in any Merger Event who affirmatively make such
an election.
		
	Consequences of Merger Events:	  	Notwithstanding Section 12.2 of the Definitions, upon the occurrence of a Merger Event, (i) the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under the Indenture to any one or more of the
nature of the Shares, the Strike Price and the Unit Entitlement to the extent an analogous adjustment is made under the Indenture and (ii)

  
 A-7 

			
		  	the Calculation Agent may, in its reasonable discretion, make any adjustment consistent with the Modified Calculation Agent Adjustment set forth in Section 12.2(e) of the Definitions to the Cap Price provided that (A) such
adjustment shall be made without regard to any adjustment to the Unit Entitlement for the issuance of additional shares as set forth in the Excluded Provisions of the Indenture; (B) if such adjustment would (but for this clause (B)) result in the
Shares including (or, at the option of a holder of Shares, may include) shares (or depositary receipts with respect to shares) of an entity or person not organized under the laws of the United States, any State thereof or the District of Columbia
and the Calculation Agent determines that (x) treating such Shares as Reference Property (as such term is defined in the Indenture) will have a material adverse effect on Dealer’s rights or obligations in respect of the Transaction, on its
Hedging Activities in respect of the Transaction or on the costs (including, without limitation, due to any increase in tax liability, decrease in tax benefit or other adverse effect on its tax position) of engaging in any of the foregoing and (y)
Dealer cannot promptly avoid the occurrence of each such material adverse effect by (I) transferring or assigning its rights and obligations under the relevant Transaction pursuant to Section 11(d) of this Master Confirmation to an affiliate of
Dealer that regularly engages in transactions similar to the Transaction or (II) amending the terms of this Master Confirmation or the Confirmation (whether because amendments would not avoid such occurrence or because Counterparty fails to agree
promptly to such amendments), no such adjustment shall be made and Cancellation and Payment (Calculation Agent Determination) shall apply; and (C) in no event shall the Cap Price be less than the Strike Price. For the avoidance of doubt, adjustments
shall be made pursuant to the provisions of subparagraphs (i) and (ii) above regardless of whether any Merger Event gives rise to an Early Conversion.
		
	Dilution Provision:	  	As set forth in the Confirmation for such Transaction
		
	Merger Provision:	  	As set forth in the Confirmation for such Transaction
		
	Nationalization, Insolvency or Delisting:	  	Cancellation and Payment (Calculation Agent Determination). In addition to the provisions of Section 12.6(a)(iii) of the Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares
are not immediately re-listed or re-traded on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed or re-traded on any such
exchange, such exchange shall thereafter be deemed to be the Exchange.

 8. Additional Disruption Events: 

 

			
	Change in Law:	  	Applicable; provided that Section 12.9(a)(ii) of the Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “or announcement of the formal or

Miscellaneous: 
 (a) [Reserved] 

(b) Alternative Calculations and Dealer Payment on Early Termination and on Certain Extraordinary Events. If Dealer owes Counterparty
any amount in connection with a Transaction hereunder pursuant to Section 12.7 or 12.9 of the Definitions (except in the case of an Extraordinary Event in which the consideration or proceeds to be paid to holders of Shares as a result of such
event consists solely of cash) or pursuant to Section 6(d)(ii) of the Agreement (except in the case of 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 (x) Event of Default of the type described in Section 5(a)(iii), (v), (vi) or (vii) of the Agreement or (y) a Termination Event of the type described in Section 5(b)(i), (ii), (iii), (iv), or (v) of the
Agreement or under “Termination upon Early Conversion” below that in the case of either (x) or (y) resulted from an event or events outside Counterparty’s control) (a “Dealer Payment Obligation”),
Counterparty shall have the right, in its sole discretion, to require Dealer to satisfy any such Dealer Payment Obligation by delivery of Termination Delivery Units (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in
writing within one Scheduled Trading Day, between the hours of 9:00 a.m. and 4:00 p.m. New York time on the Merger Date, the Announcement Date (in the case of a Nationalization or Insolvency), or the Early Termination Date or other date of
cancellation or termination, as applicable (“Notice of Dealer Termination Delivery”); provided that Counterparty shall not have the right, notwithstanding any notice to the contrary, to require Dealer to satisfy the
Dealer Payment Obligation by delivering Termination Delivery Units unless on the date of any such notice, Counterparty represents to Dealer that, as of such date, it is not aware of any material non-public information regarding
Counterparty or the Shares. Within a commercially reasonable period of time following receipt of a Notice of Dealer Termination Delivery, Dealer shall deliver to Counterparty a number of Termination Delivery Units having a cash value equal to the
amount of such Dealer Payment Obligation (such number of Termination Delivery Units to be delivered to be determined by the Calculation Agent as the number of whole Termination Delivery Units that could be purchased over a commercially reasonable
period of time with the cash equivalent of the Dealer Payment Obligation). 
 “Termination Delivery Unit” means (i) in
the case of a Termination Event, an Event of Default or an Extraordinary Event (other than an Insolvency, Nationalization or Merger Event), one Share or (ii) in the case of an Insolvency, Nationalization or Merger Event, a unit consisting of
the number or amount of each type of property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Insolvency, Nationalization or
Merger Event. If a Termination Delivery Unit consists of property other than cash or New Shares and Counterparty provides irrevocable written notice to the Calculation Agent on or prior to the Closing Date that it elects to have Dealer deliver cash,
New Shares or a combination thereof (in such proportion as Counterparty designates) in lieu of such other property, the Calculation Agent will replace such property with cash, New Shares or a combination thereof as components of a Termination
Delivery Unit in such amounts, as determined by the Calculation Agent in its discretion by commercially reasonable means, as shall have a value equal to the value of the property so replaced. If such Insolvency, Nationalization 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. 

  
 A-11 

 If the provisions of this paragraph (b) are applicable, the provisions of Sections 9.1(c), 9.8, 9.9, 9.10,
9.11, 9.12 and 10.5 of the Definitions will be applicable as if “Physical Settlement” applied to the Transaction, except that all references to “Shares” shall be read as references to “Termination Delivery Units”;
provided that the Representation and Agreement contained in Section 9.11 of the Definitions shall be modified by excluding any representations therein relating to restrictions, obligations, limitations or requirements under applicable
securities laws as a result of the fact that Buyer is the issuer of any Termination Delivery Units (or any part thereof). Notwithstanding anything to the contrary in the Definitions, Dealer may, in whole or in part, deliver securities comprising
Termination Delivery Units in certificated form to Counterparty in lieu of delivery through the Clearance System. 
 (c) No Set-Off.
Obligations under a Transaction hereunder shall not be set off against any other obligations of the parties, whether arising under the Agreement, this Master Confirmation, under any other agreement between the parties hereto, by operation of law or
otherwise, and no other obligations of the parties shall be set off against obligations under a Transaction hereunder, whether arising under the Agreement, this Master Confirmation, under any other agreement between the parties hereto, by operation
of law or otherwise, and each party hereby waives any such right of setoff. 
 (d) Transfer or Assignment. Dealer may transfer or
assign all or any part of its rights or obligations under any Transaction only with the prior written consent of Counterparty. If, as determined in Dealer’s reasonable judgment, (a) at any time an Excess Ownership Position (as defined
below) exists, and (b) Dealer is unable, after commercially reasonable efforts, to effect a transfer or assignment on pricing and terms and within a time period reasonably acceptable to it of all or a portion of one or more Transactions
pursuant to the preceding paragraph such that an Excess Ownership Position no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of any
Transaction(s), such that an Excess Ownership Position no longer exists following such partial termination. In the event that Dealer so designates an Early Termination Date with respect to a portion of any Transaction(s), a payment or delivery shall
be made pursuant to Section 6 of the Agreement and Section 11(b) of this Master Confirmation as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion of the
Transaction(s), (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction(s) shall be the only Terminated Transaction. The “Equity Percentage” as
of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates subject to aggregation with Dealer for purposes of the “beneficial ownership” test under
Section 13 of the Exchange Act and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Dealer (collectively, “Dealer Group”) “beneficially own” (within the
meaning of Section 13 of the Exchange Act) without duplication on such day and (B) the denominator of which is the number of Shares outstanding on such day. Counterparty may not transfer or assign its rights and obligations hereunder
without the prior consent of Dealer, which consent shall not be unreasonably withheld. For the avoidance of doubt, Dealer may condition its consent on any of the following, without limitation: (i) the receipt by Dealer of opinions and documents
reasonably satisfactory to Dealer in connection with such transfer or assignment, (ii) such transfer or assignment being effected on terms reasonably satisfactory to Dealer with respect to any legal and regulatory requirements relevant to
Dealer, and (iii) Equinix, Inc. (or any successor obligor under the Convertible Notes) continuing to be obligated with respect to “Notice of Merger Consideration”, “Repurchase Notices”, “Registration” and
“Conversion Rate Adjustments” following such transfer or assignment, (iv) such assignment being made to a U.S. person (as defined in the Internal Revenue Code of 1986, as amended), (v) Dealer not, as a result of such assignment,
being required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment,
(vi) no Event of Default, Potential Event of Default or Termination Event occurring as a result of such assignment, (vii) if Dealer reasonably requests, the transferee agreeing not to hedge its exposure to the Transaction, or to hedge such
exposure only pursuant to an effective registration of Equinix, Inc. (or any successor obligor under the Convertible Notes) or otherwise in compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not
expose Dealer to material risks under applicable securities laws, (viii) without limiting the generality of clause (v), Counterparty causing the transferee to make such Payee Tax Representations and to provide such tax documentation as may be
reasonably requested by Dealer to permit Dealer to determine that results described in clauses (v) and (vi) will not occur upon or after such transfer and assignment, and (ix) Counterparty being responsible for Dealer’s
reasonable out-of-pocket costs and expenses, including reasonable fees of counsel, incurred in connection with such transfer and assignment. “Excess Ownership Position” means (1) the Equity

  
 A-12 

 
Percentage exceeds 8.0%, (2) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or
any such person, a “Dealer Person”) under Section 203 of the Delaware General Corporation Law (the “DGCL Takeover Statute”) or other federal, state or local laws, regulations or regulatory orders applicable to
ownership of Shares (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership, or could be reasonably viewed as meeting any of the
foregoing, in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting, registration, filing or notification obligations or other requirements (including obtaining prior approval by a state or federal
regulator) of a Dealer Person under Applicable Laws (including, without limitation, “interested shareholder” or “acquiring Person” status under the DGCL Takeover Statute) and with respect to which such requirements have not been
met or the relevant approval has not been received minus (y) 1% of the number of Shares outstanding on the date of determination, (3) solely with respect to any Designated Repurchase Units, any Dealer Person under the organizational
documents of Counterparty owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership, or could be reasonably viewed as meeting any of the foregoing, in excess of a number of
Shares equal to (x) the number of Shares that would give rise to reporting, registration, filing or notification obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person, or would
result in an adverse effect on a Dealer Person, in each case, under the organizational documents of Counterparty and with respect to which such requirements have not been met or the relevant approval has not been received minus (y) 1% of
the number of Shares outstanding on the date of determination or (4) the Units Equity Percentage (as defined below) exceeds 9%. 
 (e)
Additional Termination Events. For any Transaction, the occurrence of (A) an “Event of Default” (as defined in the Indenture for such Transaction) with respect to Counterparty under the terms of the Convertible Notes for such
Transaction that results in an acceleration of such Convertible Notes pursuant to the terms of such Indenture, (B) an Amendment Event or (C) a Repayment Event shall be an Additional Termination Event with respect to which such Transaction
is the sole Affected Transaction and Counterparty shall be the sole Affected Party, and Seller shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement; provided that, in the case of a
Repayment Event, the Transaction(s) shall be subject to termination only in respect of the portion of the Transaction(s) corresponding to the number of Convertible Notes that cease to be outstanding in connection with or as a result of such
Repayment Event. 
 “Amendment Event” means, for any Transaction, that, without the prior written consent of
Dealer, Counterparty amends, modifies, supplements or obtains a waiver of any term of the Indenture for such Transaction or the Convertible Notes for such Transaction governing the principal amount, coupon, maturity, repurchase obligation of
Counterparty, redemption right of Counterparty, any term relating to exchange of the Convertible Notes for such Transaction (including changes to the conversion rate, the conversion price, conversion settlement dates or conversion conditions), or
any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes for such Transaction to amend, in each case where Dealer reasonably determines that such event will have a material adverse
effect on Dealer’s rights or obligations in respect of such Transaction, on its Hedging Activities in respect of such Transaction or on the costs (including, without limitation, due to any increase in tax liability, decrease in tax benefit or
other adverse effect on its tax position) of engaging in any of the foregoing. 
 “Repayment Event” means that, for
any Transaction (I) any Convertible Notes for such Transaction are repurchased (whether in connection with or as a result of a fundamental change, howsoever defined, or for any other reason) by Counterparty or any of its subsidiaries, (II) any
Convertible Notes for such Transaction are delivered to Counterparty or any of its subsidiaries in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (III) any principal of any of the
Convertible Notes for such Transaction is repaid prior to the final maturity date of such Convertible Notes (whether following acceleration of such Convertible Notes or otherwise), (IV) any Convertible Notes for such Transaction are exchanged by or
for the benefit of the holders thereof for any other securities (including, for the avoidance of doubt, Shares) of Counterparty or any of its affiliates (or any other property, or any 

  
 A-13 

 
combination thereof) pursuant to any exchange offer or similar transaction or (V) any combination of (I)-(IV); provided that (x) any conversion of the Convertible Notes for such
Transaction by holders thereof (including conversions for which the Counterparty has elected the exchange in lieu of conversion option pursuant to the Exchange in Lieu of Conversion Provision) pursuant to the terms of the Indenture for such
Transaction at the “Conversion Rate” set forth in such Indenture (determined without regard to any provision or term of the Indenture that allows Counterparty to voluntarily increase such “Conversion Rate”) shall not be a
Repayment Event and (y) any Excluded Repayment Event shall not be a Repayment Event. 
 (f) Termination upon Early Conversion.
Notwithstanding anything to the contrary in this Master Confirmation, upon the occurrence of a Conversion Date with respect to an Early Conversion other than an Early Conversion that has been validly retracted pursuant to the Retraction Provision by
the holder of the related Convertible Note: 
 (A) Counterparty shall within one Scheduled Valid Day of the Conversion Date (or, if
applicable, the final day of the “Conversion Retraction Period” (as defined in the Indenture)) for such Early Conversion provide written notice (an “Excluded Conversion Notice”) to Dealer specifying the number of Relevant
Convertible Notes converted on such Conversion Date and not validly retracted; 
 (B) such Early Conversion shall constitute an Additional
Termination Event hereunder with respect to the number of Units relating to the number of Relevant Convertible Notes surrendered for conversion in connection with such Early Conversion (the “Affected Number of Units”), in which case
(x) the sole Affected Transaction shall consist of a transaction identical to the Transaction except that Number of Units for such Affected Transaction shall equal the Affected Number of Units and Counterparty shall be deemed the sole Affected
Party and (y) the Transaction shall remain in full force and effect, except that the Number of Units subject to the Transaction immediately prior to the Conversion Date for such Early Conversion shall as of such Conversion Date be reduced by
the Affected Number of Units; 
 (C) notwithstanding anything to the contrary in the Agreement, Dealer shall designate an Early Termination
Date in respect of such Affected Transaction, which shall be no earlier than one Scheduled Valid Day following the effective date of delivery of an Excluded Conversion Notice for the related Early Conversion and no later than five Scheduled Valid
Days following such effective date; and 
 (D) for the avoidance of doubt, in determining the amount payable in respect of such Affected
Transaction pursuant to Section 6 of the Agreement (which, for the avoidance of doubt, shall take into account the Limited Make Whole Provision, if such Early Conversion relates to the conversion of Relevant Convertible Notes in connection with
which holders thereof are entitled to receive additional Shares and/or cash pursuant to the adjustments to the “Conversion Rate” (as defined in the Indenture) set forth in the Make Whole Provision), Dealer shall assume that (x) the
relevant Early Conversion and any adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred, (y) no adjustments to the Conversion Rate have occurred pursuant to the Excluded
Provisions and (z) the corresponding Convertible Notes remain outstanding. 
 For the avoidance of doubt, no event that constitutes a
Repayment Event or an Excluded Repayment Event shall be an Early Conversion. 
 (g) Status of Claims in Bankruptcy. Dealer
acknowledges and agrees that this Master Confirmation, together with any Confirmation, is not intended to convey to Dealer rights with respect to any Transaction that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings
of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to any Transaction; and
provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transactions. 

  
 A-14 

 (h) No Collateral Delivery by Counterparty. Notwithstanding any provision of this Master
Confirmation, any Confirmation or the Agreement, or any other agreement between the parties, to the contrary, the obligations of Counterparty under the Transactions are not secured by any collateral. Without limiting the generality of the foregoing,
if this Master Confirmation, the Agreement or any other agreement between the parties includes an ISDA Credit Support Annex or other agreement pursuant to which Counterparty collateralizes obligations to Dealer, then the obligations of Counterparty
hereunder will not be considered to be obligations under such Credit Support Annex or other agreement pursuant to which Counterparty collateralizes obligations to Dealer, and any Transactions hereunder shall be disregarded for purposes of
calculating any Exposure, Market Value or similar term thereunder. 
 (i) Assignment of Share Delivery to Affiliates 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 the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to
the extent of any such performance. 
 (j) Severability; Illegality. If compliance by either party with any provision of a
Transaction would be unenforceable or illegal, (i) the parties shall negotiate in good faith to resolve such unenforceability or illegality in a manner that preserves the economic benefits of the transactions contemplated hereby and
(ii) the other provisions of the Transaction shall not be invalidated, but shall remain in full force and effect. 
 (k) Waiver of
Trial by Jury. EACH OF COUNTERPARTY AND DEALER HEREBY IRREVOCABLY WAIVES (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS) ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
(WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS TRANSACTION OR THE ACTIONS OF DEALER OR ITS AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF. 

(l) Confidentiality. Notwithstanding any provision in this Master Confirmation, any Confirmation or the Agreement, in connection with
Section 1.6011-4 of the Treasury Regulations, the parties hereby agree that each party (and each employee, representative, or other agent of such party) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment
and U.S. tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such U.S. tax treatment and U.S. tax structure, other than any information for which
nondisclosure is reasonably necessary in order to comply with applicable securities laws. 
 (m) Securities Contract; Swap Agreement.
The parties hereto agree and acknowledge that Dealer is a “financial institution,” “swap participant” and “financial participant” within the meaning of Sections 101(22), 101(53C) and 101(22A) of Title 11 of the United
States Code (the “Bankruptcy Code”). The parties hereto further agree and acknowledge (A) that this Confirmation is (i) a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy
Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the
Bankruptcy Code and a “settlement payment” or a “transfer” within the meaning of Section 546 of the Bankruptcy Code, and (ii) a “swap agreement,” as such term is defined in Section 101(53B) of the
Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” a “payment amount” or “other transfer obligation” within the meaning of Section 362 of
the Bankruptcy Code and a “transfer” within the meaning of Section 546 of the Bankruptcy Code, and (B) that Dealer is entitled to the protections afforded by, among other sections, Section 362(b)(6), 362(b)(17), 362(b)(27),
362(o), 546(e), 546(g), 546(j), 548(d)(2), 555, 560 and 561 of the Bankruptcy Code. 
 (n) Postponement of Settlement. Dealer may
postpone any Potential Exercise Date or any other date of valuation or delivery by Seller or add additional Settlement Dates or any other date of valuation or 

  
 A-15 

 
delivery by Seller, with respect to some or all of the relevant Units (in which event the Calculation Agent shall make appropriate adjustments to the number of Net Shares), by at most twenty
Scheduled Trading Days, if Dealer reasonably determines that such extension is necessary or appropriate to preserve Dealer’s hedging activity hereunder in light of existing liquidity conditions (but only if there is a material decrease in
liquidity relative to Dealer’s expectations on the Trade Date) or to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty
or an affiliated purchaser of Counterparty, be in compliance with applicable legal and regulatory requirements or self-regulatory requirements, or with related policies and procedures applicable to Dealer. In connection with any Settlement Date that
is postponed pursuant to the immediately preceding sentence, if Shares are to be delivered by Dealer to Counterparty on such postponed Settlement Date and the record date for any dividend or distribution on the Shares occurs during the period from,
and including, the original Settlement Date to, but excluding, such postponed Settlement Date, then on such postponed Settlement Date, in addition to delivering such Shares, Dealer shall pay or deliver, as the case may be, to Counterparty, the per
Share amount of such dividend or distribution multiplied by the number of Shares to be delivered. 
 (o) Staggered Settlement. If
upon advice of counsel with respect to applicable legal and regulatory requirements, including any requirements relating to Dealer’s hedging activities hereunder, Dealer reasonably determines that it would not be practicable or appropriate to
deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer on a Settlement Date for a Transaction, Dealer may, by notice to the Counterparty prior to any Settlement Date (a “Nominal Settlement
Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows: 

(i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or
prior to such Nominal Settlement Date, but not prior to the beginning of the Settlement Averaging Period) or delivery times and how it will allocate the Shares it is required to deliver hereunder in connection with any Net Share Settlement among the
Staggered Settlement Dates or delivery times; and 
 (ii) the aggregate number of Shares that Dealer will deliver to
Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date. 

(p) Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a
written notice of such repurchase (a “Repurchase Notice”) on such day if, following such repurchase, the Units Equity Percentage as determined on such day is (i) equal to or greater than 6.0% and (ii) greater by 0.5% or
more than the Units Equity Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater by 0.5% or more than the Units Equity Percentage as of the date hereof). The “Units
Equity Percentage” as of any day is the fraction the numerator of which is the aggregate of the Applicable Percentage of the sum of (x) the Number of Shares for all Transactions hereunder, and (y) the product of
(A) the Number of Designated Repurchase Units for all Transactions hereunder, and (B) the Unit Entitlement, and the denominator of which is the number of Shares outstanding on such day. Counterparty agrees to indemnify and hold
harmless Dealer and its Affiliates and their respective officers, directors and controlling persons (each, a “Section 16 Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging
activities as a consequence of becoming, or of the risk of becoming, subject to the reporting and profit disgorgement provisions of Section 16 of the Exchange Act, including without limitation, any forbearance from hedging activities or
cessation of hedging activities and any losses in connection therewith with respect to any Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, to which a Section 16
Indemnified Person may become subject, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph (p), and to reimburse, upon written request, each such
Section 16 Indemnified Person for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action,
proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Section 16 Indemnified Person, such Section 16 Indemnified Person shall promptly notify Counterparty in writing,
and Counterparty, upon request of such Section 16 Indemnified Person, shall retain counsel reasonably satisfactory to 

  
 A-16 

 
such Section 16 Indemnified Person to represent such Section 16 Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of
such counsel related to such proceeding. Counterparty shall be relieved from liability to the extent that such Section 16 Indemnified Person fails to promptly notify Counterparty of any action commenced against it in respect of which indemnity
may be sought hereunder; provided that failure to notify Counterparty (i) shall not relieve Counterparty from any liability hereunder to the extent it is not materially prejudiced as a result thereof and (ii) shall not, in any
event, relieve Counterparty from any liability that it may have otherwise than on account of this paragraph (p). Counterparty shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Section 16 Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the
prior written consent of each Section 16 Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Section 16 Indemnified Person is or could have been a party and indemnity could have been
sought hereunder by any such Section 16 Indemnified Person, unless such settlement includes an unconditional release of each such Section 16 Indemnified Person from all liability on claims that are the subject matter of such proceeding on
terms reasonably satisfactory to each such Section 16 Indemnified Person. If the indemnification provided for in this paragraph (p) is unavailable to a Section 16 Indemnified Person or insufficient in respect of any losses, claims,
damages or liabilities referred to therein, then Counterparty, in lieu of indemnifying such Section 16 Indemnified Person thereunder, shall contribute to the amount paid or payable by such Section 16 Indemnified Person as a result of such
losses, claims, damages or liabilities. The remedies provided for in this paragraph (p) are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Section 16 Indemnified Person at law or in equity.
The indemnity and contribution agreements contained in this paragraph (p) shall remain operative and in full force and effect regardless of the termination of any Transaction. 

(q) Early Unwind. In the event the sale of Convertible Notes for any Transaction hereunder is not consummated pursuant to the
underwriting agreement (the “Underwriting Agreement”) dated June 9, 2009 between Counterparty and Citigroup Global Markets Inc. and J.P. Morgan Securities Inc. (the “Representatives”), as representatives of the
underwriters thereunder (the “Underwriters”) by the close of business in New York City on the Early Unwind Date set forth in the Confirmation for such Transaction, such Transaction shall automatically terminate on such Early Unwind
Date and (i) such Transaction and all of the respective rights and obligations of Dealer and Counterparty under such Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other party from
and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in connection with such Transaction either prior to or after such Early Unwind Date;
provided that, if such failure is due to a breach or default on the part of Counterparty under the Underwriting Agreement, Counterparty shall assume, or reimburse the cost of, derivatives or other transactions entered into by Dealer or one or
more of its Affiliates in connection with hedging such Transaction. The amount paid by Counterparty shall be Dealer’s actual cost of such derivatives or other transactions as Dealer informs Counterparty and shall be paid in immediately
available funds on such Early Unwind Date or, at the election of Counterparty, in lieu of such payment Counterparty may deliver to Dealer, on such Early Unwind Date, Shares with a value equal to such amount, as determined by the Calculation Agent,
in which event the parties shall enter into customary and commercially reasonable documentation relating to the registered or exempt resale of such Shares; provided that in no event shall Counterparty be obligated to deliver in excess of
1,541,787 Shares. 
 (r) Registration. Counterparty hereby agrees that if any Shares (the “Hedge Shares”) acquired
by Dealer for the purpose of hedging its obligations pursuant to the Transaction, in Dealer’s reasonable judgment based on the advice of outside counsel, cannot be sold in the U.S. public market by Dealer without registration under the
Securities Act, Counterparty shall, at its election: (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act to cover the resale of
such Hedge Shares and (A) enter into an agreement, in form and substance reasonably satisfactory to Dealer and Counterparty, substantially in the form of an underwriting agreement for a registered secondary offering of a similar size,
(B) provide accountant’s “comfort” letters in customary form for registered offerings of equity securities, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to
Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities and (E) afford Dealer a reasonable opportunity to conduct a “due diligence”
investigation with respect to Counterparty customary in scope for 

  
 A-17 

 
underwritten offerings of equity securities; provided that if Dealer, in its reasonable judgment, is not satisfied with access to due diligence materials, the results of its due diligence
investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or (iii) of this paragraph (r) shall apply at the election of Counterparty; (ii) in order to allow Dealer to sell
the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement agreements customary for private placements of equity securities of a similar size, in form and substance reasonably
satisfactory to Dealer and Counterparty, including customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Hedge
Shares from Dealer), opinions and certificates and such other documentation as is customary for private placement agreements for private placements of a similar size, all reasonably acceptable to Dealer (in which case, the Calculation Agent shall
make any adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement); or
(iii) purchase the Hedge Shares from Dealer at the price displayed under the heading “Bloomberg VWAP” on Bloomberg page EQIX.UQ <Equity> VAP (or successor thereto) in respect of the period from the scheduled opening time of the
Exchange to the Scheduled Closing Time of the Exchange on a relevant Exchange Business Day (or if such volume-weighted average price is unavailable, the market value of one Share on such Exchange Business Day, as determined by the Calculation Agent
using a volume-weighted method) on such Exchange Business Days, and in the amounts requested by Dealer. For the avoidance of doubt, unless Counterparty elects to repurchase the Hedge Shares pursuant to clause (iii) of this paragraph (r),
nothing in this Master Confirmation shall be interpreted as requiring Counterparty to repurchase the Hedge Shares or otherwise pay any amount of cash to Dealer pursuant to this paragraph (r) and under no circumstances shall Counterparty be
required to repurchase the Hedge Shares or otherwise pay any amount of cash to Dealer pursuant to this paragraph (r). This paragraph (r) shall survive the termination, expiration or early unwind of any Transaction for a period reasonably
determined by Dealer (which period shall end no later than the thirtieth consecutive Valid Day on which Counterparty has satisfied all of its obligations pursuant to this paragraph (r) and the agreements referred to herein). 

(s) Conversion Rate Adjustments. Counterparty shall provide to Dealer written notice (such notice, an “Conversion Rate
Adjustment Notice”) at least five Scheduled Trading Days prior to consummating or otherwise executing or engaging in any transaction or event other than a stock split, reverse stock split or stock dividend (an “Conversion Rate
Adjustment Event”) that would lead to a change in the “Conversion Rate” (as such term is defined in the Indenture), which Conversion Rate Adjustment Notice shall set forth the new, adjusted Conversion Rate after giving effect to
such Conversion Rate Adjustment Event (the “New Conversion Rate”). In connection with the delivery of any Conversion Rate Adjustment Notice to Dealer, Counterparty shall, concurrently with or prior to such delivery,
(x) publicly announce and disclose the Conversion Rate Adjustment Event or (y) represent and warrant that the information set forth in such Conversion Rate Adjustment Notice does not constitute material non-public information with respect
to Counterparty or the Shares. 
 (t) Counterparty’s Obligation to Pay Cancellation Amounts and Early Termination Amounts.
Dealer and Counterparty hereby agree that, notwithstanding anything to the contrary herein or in the Agreement, following Dealer’s receipt of the Premium for any Transaction from Counterparty on the Premium Payment Date for such Transaction, in
the event that (i) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to such Transaction and, as a result, Counterparty owes to Dealer an Early Termination Amount
or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Definitions, a Cancellation Amount, such amount shall be deemed to be zero. If Counterparty pays the Premium for any Transaction on the Premium
Payment Date for such Transaction, then under no circumstances shall Counterparty be required to pay any amount in addition to the Premium with respect to such Transaction, except in the case of a breach by Counterparty of a representation or
covenant hereunder. 
 (u) Method of Delivery. Whenever delivery of funds or other assets is required hereunder by or to
Counterparty, such delivery shall be effected through Agent. In addition, all notices, demands and communications of any kind relating to any Transaction between Dealer and Counterparty shall be transmitted exclusively through Agent. 

(v) Applicability of Indenture. For the avoidance of doubt, any adjustment, notice or other provision contained in this Master
Confirmation or any Confirmation hereunder related to or referencing the Indenture or the Convertible Notes shall continue to apply to the Units (including, for the avoidance of doubt, Designated Repurchase Units) irrespective of whether any
Convertible Notes remain outstanding. 

  
 A-18 

 (w) Other Adjustments Pursuant to the Definitions. Notwithstanding anything to the
contrary in this Master Confirmation, solely for the purpose of adjusting the Cap Price for any Designated Repurchase Units, the term “Potential Adjustment Event” shall have the meaning assigned to it in the Definitions (as amended by
Section 15(iii) hereof), and upon the occurrence of the declaration by Counterparty of the terms of any Potential Adjustment Event, as such term is defined in the Definitions, the Calculation Agent may, in its sole discretion, adjust the Cap
Price to preserve the fair value of the Designated Repurchase Units to Dealer; provided that in no event shall the Cap Price for such Designated Repurchase Units be less than the Strike Price. For the avoidance of doubt, the parties hereto
agree and acknowledge that the Cap Price for any Designated Repurchase Units following an adjustment pursuant to this Section 11(w) may be different than the Cap Price for any Units other than Designated Repurchase Units at such time.
