REDEMPTION AND PREPAYMENT 

Section 3.01.    Redemption. The Notes are not redeemable prior to their maturity date. 

Section 3.02.    Repurchase Offer. In the event that, pursuant to Section 4.05 hereof, the Company or a
Restricted Subsidiary is required to commence an offer to all Holders to purchase Notes (a “Repurchase Offer”), it shall follow the procedures specified below. 

The Repurchase Offer shall remain open for a period of at least 20 Business Days following its commencement, except to the extent that a
shorter or longer period is permitted or required, as the case may be, by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the
Company will purchase at the Purchase Price (as determined in accordance with Section 4.05 hereof, as the case may be) the principal amount of Notes required to be purchased pursuant to Section 4.05 hereof, as the case may be (the
“Offer Amount”) and, if required, Pari Passu Indebtedness (on a pro rata basis, if applicable), or, if less than the Offer Amount has been tendered, all Notes and Pari Passu Indebtedness tendered in response to the Repurchase Offer.
Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
 If the Purchase Date is on or after an
interest record date and on or before the related Interest Payment Date, any accrued and unpaid interest, if any, to, but not including, the Payment Date will be paid to the Person in whose name a Note is registered at the close of business on such
record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Repurchase Offer. 
 Upon the
commencement of a Repurchase Offer, the Company will deliver or cause to be delivered a notice to each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender
Notes pursuant to the Repurchase Offer. The notice, which will govern the terms of the Repurchase Offer, will state: 

(a)    that the Repurchase Offer is being made pursuant to this Section 3.02, and Section 4.05
hereof, and the length of time the Repurchase Offer will remain open; 
 (b)    the Offer Amount, the
purchase price and the Purchase Date; 
 (c)    that any Note not tendered or accepted for payment will
continue to accrue interest; 
 (d)    that, unless the Company defaults in making such payment, any Note
accepted for payment pursuant to the Repurchase Offer will cease to accrue interest after the Purchase Date; 

  
 -22- 








 (e)    that Holders electing to have a Note purchased
pursuant to a Repurchase Offer may elect to have Notes purchased in minimum denominations of $2,000, or integral multiples of $1,000 in excess thereof; 

(f)    that Holders electing to have a Note purchased pursuant to any Repurchase Offer will be required to
surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Note completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address
specified in the notice at least three days before the Purchase Date; 
 (g)    that Holders will be
entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission, email or letter setting forth the
name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 

(h)    that, if the aggregate principal amount of Notes and Pari Passu Indebtedness surrendered by holders
thereof exceeds the Offer Amount, the Trustee will select the Notes to be purchased on a pro rata basis based on the principal amount of Notes and such Pari Passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the
Trustee so that no Notes in denominations of $2,000 or less will be purchased in part); and 

(i)    that Holders whose Notes were purchased only in part will be issued new Notes of the applicable
series equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
 On or
before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof validly tendered pursuant to the Repurchase Offer or if less than the
Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for
payment by the Company in accordance with the terms of this Section 3.02. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) deliver to each
tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will
authenticate and deliver (or cause to be transferred by book entry) such new Note to such Holder in a principal amount equal to any unpurchased portion of the Note surrendered. Notwithstanding any other provision in the Indenture to the contrary,
neither an Opinion of Counsel nor an Officers’ Certificate is required for the Trustee to authenticate such new Note. Any Note not so accepted shall be promptly returned by the Company to the Holder thereof. The Company will publicly announce
the results of the Repurchase Offer on or as soon as practicable after the Purchase Date. 
 Other than as specifically provided in this
Section 3.02 or Section 4.05 of this Supplemental Indenture, as applicable, any purchase pursuant to this Section 3.02 shall be made pursuant to the applicable provisions of Section 3.01 through Section 3.06 of the Base
Indenture.

under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes, the information required to be delivered pursuant to Rule 144(c)(2) and/or Rule 144A(d)(4)

 [Back of Note] 

5.00% Senior Notes due [        ] 20[    ] 

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

(1) INTEREST. Equinix, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount
of this Note at 5.00% per annum from April 2, 2018 until maturity. The Company will pay interest semi-annually in arrears on April 2 and October 2 of each year, or if any such day is not a Business Day, on the next succeeding Business
Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date;
provided further that the first Interest Payment Date shall be October 2, 2018. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from
time to time on demand at a rate that is 1% per annum in excess of the rate then in effect to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed daily on the basis of a 360-day year of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except
defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.14 of the Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest, if any, at the office or agency of the Company
maintained for such purpose within or without the United States, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire
transfer of immediately available funds will be required with respect to principal of and interest, premium on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying
Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

(3) PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent
and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in the capacity of Paying Agent or Registrar. 

(4) INDENTURE. The Company issued the Notes under an Indenture, dated as of December 12, 2017 (the “Base
Indenture” and, as supplemented by the Supplemental Indenture (as defined below), the “Indenture”), by and between the Company and the Trustee, as supplemented by that certain Third Supplemental Indenture, dated as of
April 2, 2018, by and between the Company and the Trustee (the “Supplemental Indenture”). The terms of this Note include those stated in the Indenture and those made part of the Indenture by reference to the TIA. The Notes are
subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall
govern and be controlling. The Notes are unsecured obligations of the Company. 

  
 A-4 








 (5) REPURCHASE AT THE OPTION OF HOLDER. 

(a) In the event that the Company or a Restricted Subsidiary is required to commence an offer to all Holders to purchase Notes pursuant to
Section 4.05 of the Supplemental Indenture, it will comply with the terms set forth in the Supplemental Indenture, including Section 3.02 thereof. 

(b) If a Change of Control Triggering Event occurs, the Company will be required to make an offer (a “Change of Control
Offer”) to each Holder to repurchase all or any part of such Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest on the Notes repurchased
to the date of repurchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control Triggering Event, the Company will deliver a notice
to each Holder, with a copy to the Trustee, setting forth the procedures governing the Change of Control Offer as required by the Indenture. 

(6) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not issue, register the transfer of or exchange any Notes during the period between a record date and
the next succeeding Interest Payment Date. 
 (7) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner
for all purposes. 
 (8) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture and the Notes of any Series
may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes of such Series voting as a single class (including, without limitation, consents obtained in connection
with a tender offer or exchange offer for purchase of, any Series of Notes), and any existing Default or Event or Default, other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on any Series of
Notes (except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of the Indenture and the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the
then outstanding Notes of such Series voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for purchase of, any Series of Notes). Without the consent of any Holder of Notes,
the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency; provide for the assumption by a Surviving Entity of the obligations of the Company under the Indenture; provide for uncertificated Notes in
addition to or in place of certificated Notes; secure the Notes, add to the covenants of the Company for the benefit of the holders of the Notes or surrender any right or power conferred upon the Company; make any change that does not adversely
affect the rights of any holder of the applicable Series of Notes; comply with any requirement of the Commission in connection with the qualification of the Indenture under the TIA; evidence and provide for the acceptance of appointment by a
successor Trustee; or make any amendment to the provisions of the Indenture relating to the transfer and legending of the Notes as permitted by the Indenture, including, without limitation to facilitate the issuance and administration of the Notes;
provided that (i) compliance with the Indenture as so amended would not result in the Notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and
adversely affect the rights of Holders to transfer the Notes. 

  
 A-5 








 (9) DEFAULTS AND REMEDIES. Events of Default with respect to the Notes include:
(i) default for 30 days in the payment when due of interest on, with respect to the Notes; (ii) default in the payment when due (at maturity or otherwise) of the principal on the Notes (including the failure to make a payment to purchase
Notes tendered pursuant to a Change of Control Offer); (iii) failure by the Company for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single
class to comply with any of the other covenants or agreements in the Indenture (except (i) in the case of a default with respect to Section 5.01 of the Supplemental Indenture, which will constitute an Event of Default with such notice
requirement but without such passage of time requirement and (ii) as otherwise provided in the last paragraph of Section 4.03 of the Base Indenture); (iv) the failure to pay at final maturity (giving effect to any applicable grace periods
and any extensions thereof) the stated principal amount of any Indebtedness of the Company or any Restricted Subsidiary of the Company, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded,
annulled or otherwise cured within 30 days of receipt by the Company or such Restricted Subsidiary of notice of any such acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such
Indebtedness in default for failure to pay principal at final stated maturity or which has been so accelerated (in each case with respect to which the 30-day period described above has passed), equals
$350.0 million or more at any time; (v) failure by the Company to pay final non-appealable judgments entered by a court or courts of competent jurisdiction against the Company or any Restricted
Subsidiary of the Company in amounts aggregating in excess of $350.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; (vi) the Company or any of its Restricted Subsidiaries that is a Material Subsidiary
or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Material Subsidiary, pursuant to or within the meaning of Bankruptcy Law, commences a voluntary case, consents to the entry of an order for relief
against it in an involuntary case, consents to the appointment of a custodian for it or for all or substantially all of its property, makes a general assignment for the benefit of its creditors, or an admission by the Company in writing of its
inability to pay its debts as they become due; (vii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that is for relief against the Company or any of its Restricted Subsidiaries that is a Material Subsidiary
or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Material Subsidiary in an involuntary case; appoints a custodian of the Company or any of its Restricted Subsidiaries that is a Material Subsidiary or
any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Material Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries that is a Material Subsidiary or
any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Material Subsidiary or orders the liquidation of the Company or any of its Restricted Subsidiaries that is a Material Subsidiary or any group of Restricted
Subsidiaries of the Company that, taken together, would constitute a Material Subsidiary and the order or decree remains unstayed and in effect for 60 consecutive days; or (viii) an Event of Default with respect to any other outstanding Series
of Notes. 
 If any Event of Default with respect to outstanding Notes occurs and is continuing, the Trustee or the Holders of at least 25%
in aggregate principal amount of the then outstanding Notes may declare the principal of, and accrued and unpaid interest on all the Notes to be due and payable by notice in writing to the Company and the Trustee specifying the respective Event of
Default and that it is a “notice of acceleration” and the same shall be immediately due and payable. 
 Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency occurring with respect to the Company, all unpaid principal of and accrued and unpaid interest on all of the outstanding Notes will become due and
payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from 

  
 A-6 








 
Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium, if any) if it
determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders, rescind an acceleration or waive any existing
Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes. The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company is required, within five Business Days of any Officer becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or
Event of Default. 
 (10) TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual or any other capacity, may become the
owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. 

(11) NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator, agent, stockholder or Affiliate
of the Company, as such, shall have any liability for any obligations of the Company under the Notes or under the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by
accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for the issuance of the Notes. 

(12) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

 (13) ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in

Indenture. Requests may be made to:
