 Dear Sirs and Mesdames:

proposes to sell to the several underwriters named on SCHEDULE A hereto (the “Underwriters”) an aggregate of 5,150,000 outstanding shares (the “Firm Securities”) of Common Stock, par value $0.001 per
share (the “Securities”), of Equinix, Inc., a Delaware corporation (the “Company”), and also proposes to sell to the Underwriters, at the option of the Underwriters, an aggregate of not more than 739,549 additional
outstanding shares (the “Optional Securities”) of the Securities as set forth below. The Firm Securities and the Optional Securities are herein collectively called the “Offered Securities.” 
  
 The Company has filed with the Securities and Exchange Commission (the
“Commission”) a registration statement under the Securities Act on Form S-3 (File No. 333-128857), including a prospectus (the “Company Basic Prospectus”) relating to the Offered Securities. Such registration
statement, as amended as of the date of this agreement (the “Underwriting Agreement”) and, in the event any post-effective amendment thereto becomes effective prior to the Closing Date, including the information (if any) deemed to
be part of such registration statement (including any information incorporated therein by reference) at the time of effectiveness pursuant to Rule 430A under the Securities Act of 1933, as amended, and the rules and regulations of the Commission
thereunder (collective, the “Securities Act”), is hereinafter referred to as the “Company Registration Statement;” any preliminary prospectus supplement to the Company Basic Prospectus relating to the Offered
Securities, together with the Company Basic Prospectus, is hereinafter referred to as a “Company Preliminary Prospectus;” and the final prospectus supplement to the Company Basic Prospectus relating to the Offered Securities in the
form first used to confirm sales of the Offered Securities is hereinafter referred to as the “Company Final Prospectus” (including, in the case of all references to the Company Registration Statement or the Company Final Prospectus,
unless the context requires otherwise, documents incorporated by reference therein pursuant to Item 12 of Form S-3 of the Securities Act (the “Incorporated Documents”)). The terms “supplement” and

Prospectus shall include all documents subsequently filed (but not to the extent all or a portion of such documents are furnished) by the Company with the

Company has filed an abbreviated registration statement to register additional shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Company Registration Statement”), then any reference herein to the
term “Company Registration Statement” shall be deemed to include such Rule 462 Company Registration Statement.

 (viii) the sale of the
Offered Securities by the Selling Stockholder is not prompted by any material non-public information concerning the Company which is not set forth in the Company Final Prospectus. 
  
 3. Purchase Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements
herein contained, but subject to the terms and conditions herein set forth, the Selling Stockholder agrees to sell to the Underwriters, and the Underwriters agree, severally and not jointly, to purchase from the Selling Stockholder, at a purchase
price of $34.3035 per share (the “Purchase Price”), the respective numbers of Firm Securities set forth opposite the names of the Underwriters in SCHEDULE A hereto. 
  
 The Selling Stockholder will deliver the Firm Securities to the
Representatives for the respective accounts of the Underwriters in book-entry form through the Depository Trust Company (the “DTC”), against payment of the aggregate Purchase Price for the Firm Securities in Federal (same day) funds
by official bank check or checks or wire transfer to an account designated by the Selling Stockholder at 10:30 a.m., New York City time, on November 16, 2005, and shall occur at the offices of Gunderson Dettmer Stough Villeneuve
Franklin & Hachigian LLP, located at 155 Constitution Drive, Menlo Park, California 94025, or at such other location and/or such other time not later than seven full business days thereafter as the Representatives determine, such time being
herein referred to as the “First Closing Date.” For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds
and delivery of securities for all the Offered Securities sold pursuant to the offering. 
  

 7 

 In addition, upon written notice from the Representatives given to the Company and the Selling
Stockholder not more than 30 days subsequent to the date of the Company Final Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the Purchase Price. The Selling Stockholder agrees to sell to the Underwriters
the number of shares of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of each Underwriter in the
same proportion as the number of Firm Securities set forth opposite such Underwriter’s name bears to the total number of Firm Securities (subject to adjustment by the Representatives to eliminate fractions) and may be purchased by the
Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and
delivered. Subject to the foregoing, the right to purchase the Optional Securities or any portion thereof may be exercised at any time, but only once, upon notice by the Representatives to the Company and the Selling Stockholder. 
  
 The time and location for the delivery of and payment for the Optional
Securities, being herein referred to as an “Optional Closing Date,” which may be the First Closing Date (the First Closing Date and the Optional Closing Date, if any, being sometimes referred to as a “Closing
Date”), shall be determined by the Representative but shall be not later than five full business days after written notice of election to purchase Optional Securities is given. Delivery of the Optional Securities to the Representatives for
the respective accounts of the Underwriters shall be made by the Selling Stockholder in book-entry form through the DTC against payment by the Underwriters through the Representatives of the Purchase Price therefor to or upon the order of the
Selling Stockholder by wire transfer payable in same-day funds to the account specified by the Selling Stockholder. 
  
 4. Terms of Public Offering. The Selling Stockholder and the Company are advised by the Underwriters that they propose to make a public offering of
the Offered Securities as soon after the Company Registration Statement and this Underwriting Agreement have become effective as in the Representatives’ judgment is advisable. The Selling Stockholder and the Company are further advised by the
Underwriters that the Offered Securities are to be offered to the public initially at $35.64 per share (the “Public Offering Price”), and to certain dealers selected by it at a price that represents a concession not in excess of
$0.8019 per share under the Public Offering Price, and that the Underwriters may allow, and such dealers may re-allow, a concession, not in excess of $0.10 per share, to certain other dealers. 
  
 5. Lock-Up Agreement. The Company agrees with each of the Underwriters
and the Selling Stockholder, in each case, that: 
  
 (a) for the Lock-Up Period (as defined below) the Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating
to any additional Securities or securities convertible into or exchangeable or exercisable for any Securities, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the
Representatives, except that the Company shall not be prohibited from causing the issuance of: (i) Securities pursuant to the conversion or exchange of convertible or exchangeable securities issuable or exchangeable for Securities or upon the
exercise of warrants or options exercisable for Securities, in each case outstanding on the date hereof; (ii) employee stock options of the Company exercisable for Securities pursuant to the terms of a plan of the Company in effect on the date
hereof; or (iii) any Securities or any securities convertible into or exchangeable or exercisable for any Securities, up to a maximum aggregate market value at the time of issuance of $30 million, in connection with a business acquisition by
the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise, subject to the condition that any recipient of such Securities agrees to sign and does sign a lock-up agreement substantially in the form of
EXHIBIT A hereto, the obligations under which shall, likewise, terminate or expire no later than the expiration of the Lock-Up Period; and, to the extent required by applicable law or stock market listing requirements, the Company may
publicly disclose the intention to cause such an issuance of securities. 
  
 (b) the Lock-Up Period will commence on the date hereof and will continue and include the date 45 days after the date of the Company Final Prospectus, or such earlier date that the Representatives consent to in
writing; provided, however, that if (i) during the last 17 days of the Lock-Up Period, the 

  

 8 

 
Company releases earnings results or material news or a material event relating to the Company occurs, or (ii) prior to the expiration of the Lock-Up
Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning
on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension (such initial period, and such initial period as extended as set
forth above, as the case may be, the “Lock-Up Period”). The Company will provide the Representatives with notice of any announcement described in clause (ii) of the preceding sentence that gives rise to an extension of the
Lock-Up Period. 
  
 6. Conditions to the Obligations of the
Underwriters. The obligations of the several Underwriters to purchase and pay for the Offered Securities on the applicable Closing Date will be subject to (1) the condition that the Company Registration Statement shall have been effective
not later than 4:00 P.M. (New York City time), on the date hereof, (2) the accuracy of the representations and warranties on the part of the Company and the Selling Stockholder herein, in each case as of and on the date hereof and such Closing
Date, (3) the accuracy of the statements of Company officers made pursuant to the provisions hereof, (4) the performance by the Company and the Selling Stockholder of their obligations hereunder and (5) the following additional
conditions precedent: 
  
 (a) subsequent to the
execution and delivery of this Underwriting Agreement, there shall not have occurred any: (i) downgrading in the rating of the securities of the Company by any “nationally recognized statistical rating organization” (as defined for
purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of the Company (other than an announcement with positive implications of a possible upgrading,
and no implication of a possible downgrading, of such rating); (ii) change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of the Representatives, be
likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iii) change, or any development involving a

 (d) Promptly after receipt by an indemnified party (the “Indemnified Party”) under this Section 8 of notice of the
commencement of any action, such Indemnified Party will, if a claim in respect thereof is to be made against an indemnifying party (the “Indemnifying Party”) under subsection (a), (b) or (c) above, notify the Indemnifying
Party of the commencement thereof; but the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have to an Indemnified Party otherwise than under
subsection (a), (b) or (c) above. In case any such action is brought against any Indemnified Party and it notifies an Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein and, to

Section 8 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation. No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending or threatened action in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party unless such settlement
(i) includes an unconditional release of such Indemnified Party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to
act by or on behalf of an Indemnified Party.

 (e) If the indemnification provided for in this Section 8 is unavailable or
insufficient to hold harmless an Indemnified Party under subsection (a), (b) or (c) above, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of the losses, claims, damages or
liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the
other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in
clause (i) above but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or
liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total
net proceeds from the offering (before deducting expenses) received by the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Stockholder or the Underwriters and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim which is the subject of this subsection (e).
Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute
are several in proportion to their respective underwriting obligations and not joint. 
  
 (f) The obligations of the Company and the Selling Stockholder under this Section 8 shall be in addition to any liability which the
Company and the Selling Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each Underwriter, its partners, members, directors, officers and its affiliates and each person, if any, who controls any Underwriter
within the meaning of the Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the
same terms and conditions, to the Company, its directors and officers and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act and the Selling Stockholder, its affiliates, directors and officers
and each person, if any, who controls the Selling Stockholder within the meaning of the Securities Act or the Exchange Act. 
  
 9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the
First or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that
the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Selling Stockholder for the purchase of such Offered Securities by other persons, including any of the Underwriters, but
if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed
but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of
Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives and the Selling Stockholder for the purchase of such Offered Securities by other persons are not made within
36 hours after such default, this Underwriting Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder, except as provided in Section 7(b) (provided that if such default
occurs with respect to Optional Securities after the First Closing Date, this Underwriting Agreement will 

  

 18 

 
not terminate as to the Firm Securities) hereof. As used in this Underwriting Agreement, the term “Underwriter” includes any person
substituted for an Underwriter under this Section 9. Nothing herein will relieve a defaulting Underwriter from liability for its default (including, without limitation, for the expenses incurred by the Company or the Selling Stockholder).

  
 10. Survival of Certain Representations and
Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Selling Stockholder, the Company or their respective officers and of the several Underwriters set forth in or made pursuant to this
Underwriting Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Selling Stockholder, the Company or any of their respective
representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Underwriting Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the
Offered Securities by the Underwriters is not consummated, the respective obligations of the Company, the Selling Stockholder and the Underwriters pursuant to Section 7(b) and Section 14 shall remain in effect. 
  
 11. Notices. All communications hereunder will be in writing and:

 12. Termination. This Underwriting Agreement shall be
subject to termination, by notice given by the Representatives to the Company and the Selling Stockholder, if: (a) after the execution and delivery of this Underwriting Agreement and prior to any Closing Date (i) trading generally shall
have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange or the National Association of Securities Dealers, Inc.; (ii) trading of any securities of the Company shall
have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities in New York shall have been declared by either federal or New York State authorities; or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the judgment of the Representatives, is material and adverse; and (b) in the case of any of the events specified in
clauses (a)(i) through (iv), such event, individually or together with any other such event, makes it, in the judgment of the Representatives, impracticable to market the Offered Securities on the terms and in the manner contemplated in the Company
Final Prospectus; provided that, if any such event occurs after the First Closing Date, this Underwriting Agreement will not terminate as to the Firm Securities. 
  
 13. Effectiveness. This Underwriting Agreement shall become effective upon the execution and delivery hereof by the
parties hereto. 
  

 19 

 14. Expenses. If this Underwriting Agreement shall be terminated before the First Closing Date
(a) because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Underwriting Agreement, or if for any reason the Company shall be unable to perform its obligations under this
Underwriting Agreement, the Company will reimburse the Underwriters for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by the Underwriters in connection with this Underwriting Agreement and the
offering contemplated hereunder, or (b) because of any failure or refusal on the part of the Selling Stockholder to comply with the terms or to fulfill any of the conditions of this Underwriting Agreement, or if for any reason the Selling
Stockholder shall be unable to perform its obligations under this Underwriting Agreement, the Selling Stockholder will reimburse the Underwriters for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably
incurred by the Underwriters in connection with this Underwriting Agreement and the offering contemplated hereunder). 
  
 15. Successors. This Underwriting Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and
the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder. 
  
 16. Representation. The Representatives will act for the several Underwriters in connection with the transactions contemplated by this Underwriting
Agreement, and any action under this Underwriting Agreement taken by the Representatives will be binding upon all the Underwriters. 
  
 17. Counterparts. This Underwriting Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but
all such counterparts shall together constitute one and the same agreement. 
  
 18. Absence of Fiduciary Relationship. The Company and the Selling Stockholder acknowledge and agree that: 
  
 (a) the purchase and sale of the Securities pursuant to this Underwriting Agreement is an arm’s-length commercial transaction by and
among the Company, the Selling Stockholder and the Underwriters; 
  
 (b) in connection therewith, and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of either the Company or the Selling Stockholder;

  
 (c) no Underwriter has assumed an advisory or
fiduciary responsibility in favor of either the Company or the Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising either
the Company or the Selling Stockholder on other matters) or any other obligation to either the Company or the Selling Stockholder (except the obligations expressly set forth in this Underwriting Agreement or the Terms Agreement); 
  
 (d) the Company and the Selling Stockholder have each
consulted their own legal and financial advisors to the extent they deemed appropriate. The Company and the Selling Stockholder agree they will not claim that the Underwriters, or any of them, have rendered advisory services of any nature or
respect, or owe a fiduciary or similar duty to the Company or the Selling Stockholder, in connection with such transaction or the process leading thereto. 
  
 19. Applicable Law; Jurisdiction. This Underwriting Agreement shall be governed by, and construed in accordance with, the laws of the State of
New York, without regard to principles of conflicts of laws. The parties hereto submit to the non-exclusive jurisdiction of the federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or
relating to this Underwriting Agreement or the transactions contemplated hereby. 
  
 If the foregoing is in accordance with your understanding, kindly sign and return to each other party hereto one of the counterparts hereof, whereupon it will become a binding agreement by and among the parties
hereto, in accordance with the terms set forth above.

 of the several Underwriters for the SAILS Offering (as defined below) 
 Eleven Madison Avenue 
 New York, New York 10010-3629 
  
 Dear
Sirs and Mesdames: 
  
 REFERENCE IS HEREBY MADE to (a) that
certain Underwriting Agreement (the “Underwriting Agreement”), to which the Shares Offering Representatives, as representatives of the several underwriters named or to be named on SCHEDULE A thereto (the “Shares
Underwriters”), are or expect to become parties along with Equinix, Inc., a Delaware corporation (the “Company”), and i-STT Investments Pte. Ltd., a corporation organized under the laws of the Republic of Singapore (the
“Selling Stockholder”) and (b) that certain Terms Agreement (the “Terms Agreement”) to which the SAILS Offering Representative, as representative of the several underwriters named or to be named on
SCHEDULE A thereto (the “SAILS Underwriters”), are or expect to become parties along with the Company, the Selling Stockholder, i-STT Investments (Bermuda) Ltd., a Bermuda corporation, and Credit Suisse First Boston
(USA), Inc., a Delaware corporation. The offering of common stock of the Company (the “Common Stock”) to be made pursuant to the Underwriting Agreement is referred to herein as the “Shares Offering” and the offering
of notes exchangeable into Common Stock to be made pursuant to the Terms Agreement is referred to herein as the “SAILS Offering.” Except as otherwise set forth herein, all capitalized terms used but not defined herein shall be
ascribed the meanings assigned to such terms in the Underwriting Agreement or the Terms Agreement, as the case may be. 
  
 As an inducement to the Shares Underwriters to execute the Underwriting Agreement, pursuant to which an offering will be made that is intended to result
in an orderly market for Common Stock, and as an inducement to the SAILS Underwriters to execute the Terms Agreement, pursuant to which an offering will be made that is intended to result in an orderly market for securities exchangeable for Common
Stock, the undersigned hereby agrees that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly,
any Common Stock or securities convertible 

 into or exchangeable or exercisable for any Common Stock, enter into a transaction which would have the same effect, or
enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of any Common Stock, whether any such aforementioned transaction is to be settled by delivery of the Common Stock or
such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written
consent of both the Shares Offering Representatives and the SAILS Offering Representative. In addition, the undersigned agrees that, without the prior written consent of both the Shares Offering Representatives and the SAILS Offering Representative,
it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for any Common Stock. 
  
 The Lock-Up Period will commence on the date of the preliminary prospectus
supplement of the Company relating to the Shares Offering or, if earlier, the date of the preliminary prospectus supplement of the Company to be used in connection with the SAILS Offering, and will continue until and include the date 45 days after
the date of the final prospectus supplement of the Company relating to the Shares Offering or, if later, the date of the final prospectus supplement of the Company to be used in connection with the SAILS Offering, or such earlier date that both the
Shares Offering Representatives and the SAILS Offering Representative consent to in writing; provided, however, that if (1) during the last 17 days of the Lock-Up Period, the Company releases earnings results or material news or a material
event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then in each case
the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless both the Shares Offering
Representatives and the SAILS Offering Representative waive, in writing, such extension (such initial period, and such initial period as extended as set forth above, as the case may be, the “Lock Up Period”). 
  
 The undersigned hereby acknowledges and agrees that written notice of any
extension of the Lock-Up Period pursuant to the immediately preceding paragraph (which shall include information on when the Lock-Up Period is expected to expire pursuant to such extension) will be delivered by the Shares Offering Representatives or
the SAILS Offering Representative to the Company and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking
any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the Lock-Up Period, it will give notice thereof to the
Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as may have been extended pursuant to the previous paragraph) has expired. 
  
 Any Common Stock received upon exercise of options granted to the undersigned
will also be subject to this Lock-Up Agreement. Any Common Stock acquired by the undersigned in the open market after the date of the final prospectus supplement of the Company relating to the Shares Offering or, if later, the date of the final
prospectus supplement of the Company to be used in connection with the SAILS Offering, will not be subject to this Lock-Up Agreement. A transfer of Common Stock to a family member or trust may be made, provided the transferee agrees to be bound in
writing by the terms of this Lock-Up Agreement prior to such transfer and no filing by any party (donor, donee, transferor or transferee) under the Securities Act shall be required or shall be voluntarily made in connection with such transfer (other
than a filing on a Form 5 made after the expiration of the Lock-Up Period). In the event that the undersigned is an officer of the Company, the programmatic sales on behalf of the undersigned under any 10b5-1 sales plan in existence prior to the
date of this Lock-Up Agreement (a true and correct copy of which has been provided to the Shares Offering Representatives and the SAILS Offering Representative) will not be subject to this Lock-Up Agreement. 
  
 In furtherance of the foregoing, the Company and its transfer agent and
registrar are hereby authorized to decline to make any transfer of Common Stock if such transfer would constitute a violation or breach of this Lock-Up Agreement 
  
 This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns
of the undersigned. This Lock-Up Agreement shall lapse and become null and void if (i)

 neither the Underwriting Agreement nor the Terms Agreement shall have been executed on or before February 28, 2006,
(ii) before February 28, 2006, the Selling Stockholder notifies the Company, the Shares Offering Representatives and the SAILS Offering Representative in writing that it does not intend to enter into both the Underwriting Agreement and the
Terms Agreement or (iii) to the extent it has been executed, (A) the Underwriting Agreement shall have been terminated prior to the First Closing Date (as defined therein) in accordance with its terms and (B) the Terms Agreement shall
have been terminated prior to Closing Date (as defined therein) and in accordance with its terms. This Lock-Up Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

 (B) require any consents, approvals or authorizations to be obtained by the Selling Stockholder from, or any registrations, declarations or filings to be

 of the several Underwriters for the SAILS Offering (as defined below) 
 Eleven Madison Avenue 
 New York, New York 10010-3629 
  
 Dear
Sirs and Mesdames: 
  
 REFERENCE IS HEREBY MADE to (a) that
certain Underwriting Agreement (the “Underwriting Agreement”), to which the Shares Offering Representatives, as representatives of the several underwriters named or to be named on SCHEDULE A thereto (the “Shares
Underwriters”), are or expect to become parties along with Equinix, Inc., a Delaware corporation (the “Company”), and i-STT Investments Pte. Ltd., a corporation organized under the laws of the Republic of Singapore (the
“Selling Stockholder”) and (b) that certain Terms Agreement (the “Terms Agreement”) to which the SAILS Offering Representative, as representative of the several underwriters named or to be named on
SCHEDULE A thereto (the “SAILS Underwriters”), is or expects to become a party along with the Company, i-STT Investments (Bermuda) Ltd., a Bermuda corporation, and Credit Suisse First Boston (USA), Inc., a Delaware
corporation. The offering of common stock of the Company (the “Common Stock”) to be made pursuant to the Underwriting Agreement is referred to herein as the “Shares Offering” and the offering of securities
exchangeable into Common Stock to be made pursuant to the Terms Agreement is referred to herein as the “SAILS Offering.” Except as otherwise set forth herein, all capitalized terms used but not defined herein shall be ascribed the
meanings assigned to such terms in the Underwriting Agreement or the Terms Agreement, as the case may be. 
  
 As an inducement to the Shares Underwriters to execute the Underwriting Agreement, pursuant to which an offering will be made that is intended to result
in an orderly market for Common Stock, and as an inducement to the SAILS Underwriters to execute the Terms Agreement, pursuant to which an offering will be made that is intended to result in an orderly market for securities exchangeable into Common
Stock, the undersigned hereby agrees that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to 

 sell, pledge or otherwise dispose of, directly or indirectly, any Common Stock or securities convertible into or
exchangeable or exercisable for any Common Stock, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of any
Common Stock, whether any such aforementioned transaction is to be settled by delivery of the Common Stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to
enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of the Representatives. In addition, the undersigned agrees that it will not, during the Lock-Up Period, make any demand for or
exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for any Common Stock. 
  

The Lock-Up Period will commence on the date hereof and will continue until and include the date 45 days after the date of the final prospectus
supplement to be used in connection with the Shares Offering or, if later, the date of the final prospectus supplement of the Company to be used in connection with the SAILS Offering, or such earlier date that both the Shares Offering
Representatives and the SAILS Offering Representative consent to in writing; provided, however, that if (1) during the last 17 days of the Lock-Up Period, the Company releases earnings results or material news or a material event
relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then in each case the
Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless both the Shares Offering
Representatives and the SAILS Offering Representatives waive, in writing, such extension (such initial period, and such initial period as extended as set forth above, as the case may be, the “Lock-Up Period”). 
  
 The undersigned hereby acknowledges and agrees that written notice of any
extension of the Lock-Up Period pursuant to the immediately preceding paragraph (which shall include information on when the Lock-Up Period is expected to expire pursuant to such extension) will be delivered by the Shares Offering Representatives
and the SAILS Offering Representative to the Selling Stockholder and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any
transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such
action unless it has received written confirmation from the Company that the Lock-Up Period (as may have been extended pursuant to the previous paragraph) has expired. 
  
 Notwithstanding the foregoing, the restrictions in the second paragraph above shall not apply to: 
  
 (a) transactions relating to Common Stock or other securities of the Company
acquired in open market transactions after the completion of the offering of the Common Stock contemplated by the Underwriting Agreement; 
  
 (b) transfers of Common Stock or any securities convertible into Common Stock as a bona fide gift, provided that in the case of any such
transfer, each such donee shall sign and deliver a lock-up agreement substantially in the form of this Lock-Up Agreement prior to such transfer; 
  
 (c) transfers of shares of Common Stock or any securities convertible into Common Stock to stockholders or majority-owned subsidiaries of the undersigned,

of Contract Shares that it may be required to deliver at maturity of the Forward Purchase Agreement (the “Collateral Agreement” and, together with the Forward Purchase Agreement, the “Forward Documents”).

  
 The representations, warranties and agreements among Equinix, the Selling
Stockholder and the Underwriters with respect to the Contract Shares that will be delivered at maturity of the SAILS and related matters are set forth in Part A of this Terms Agreement (this “Agreement”). The representations,

“Commission”) a registration statement under the Securities Act on Form S-3 (File No. 333-128857), including a prospectus (the “Equinix Basic Prospectus”), relating to the Common Stock. Such registration

of such registration statement (including any information incorporated therein by reference) at the time of effectiveness pursuant to Rule 430A under the Securities Act of 1933, as amended, and the rules and regulations of Commission thereunder
(collectively, the “Securities Act”) is hereinafter referred to as the “Equinix Registration Statement;” any preliminary prospectus supplement to the Equinix Basic Prospectus relating to the Contract Shares together

“amendment” or “amend” with respect to the Equinix Registration Statement, any Equinix Preliminary Prospectus and the Equinix Final Prospectus shall include all documents subsequently filed (but not to the extent
all or a portion of such documents are furnished) by Equinix with the Commission pursuant to the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange

 (xxiv) the accountants who certified the financial statements and supporting schedules included in the Equinix Registration Statement are

Subsidiaries in connection with any actual or proposed transaction) which might subject Equinix or any of the Subsidiaries, or any other individual or entity to any damage or penalty in any civil, criminal or governmental litigation or proceeding
(domestic or foreign), which could reasonably be expected to have an Equinix Material Adverse Effect, if not given in the past, might have had an Equinix Material Adverse Effect, or if not continued in the future, might have an Equinix Material
Adverse Effect; 
  
 (xxvii) none of Equinix nor

Stockholder (each, a “Selling Stockholder Material Adverse Effect”); 
  
 (ii) this Agreement has been duly authorized, executed and delivered by the Selling Stockholder and the Forward Documents have been duly
authorized, executed and delivered by the Selling Stockholder; and each of the Forward Purchase Agreement and the Collateral Agreement constitutes a valid and legally binding agreement of the Selling Stockholder enforceable against the Selling

the Selling Stockholder of its obligations under, this Agreement and the Forward Documents will not contravene any provision of applicable law or the bye-laws of the Selling Stockholder, or any material agreement or other instrument binding upon the
Selling Stockholder or any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Selling Stockholder, except for any such contravention as would not have a Selling Stockholder Material Adverse Effect, and

Purchase Agreement free and clear of all liens, encumbrances, equities and claims, except for those created pursuant to the Collateral Agreement or otherwise created by CSFB Capital, and, assuming that CSFB Capital acquires its interest in such
Contract Shares on the Exchange Date in accordance with the terms of the Forward Purchase Agreement without notice of any adverse claim (within the meaning of Section 8-105 of the New York Uniform Commercial Code (“UCC”), CSFB
Capital will have acquired the Contract Shares free of any adverse claim (within the meaning of Section 8-102(a)(1) of the UCC); 
  
 (vii) none of the information relating to the Selling Stockholder Entities that was furnished to Equinix in writing by either of the
Selling Stockholder Entities expressly for use in any Equinix Registration Statement, any Equinix Preliminary Prospectus, the Equinix Final Prospectus or any amendment or supplement thereto includes, or will include, any untrue statement of a
material fact or omits, or will omit, to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. In addition, the Selling
Stockholder has reviewed the Equinix Registration Statement, any Equinix Preliminary Prospectus and the Equinix Final Prospectus and represents and warrants that it has no reason to believe that any such document includes any untrue statements of a
material fact or omits to state any material fact required to be stated therein or necessary to make the statement therein, in light of the circumstances under which they were made, not misleading; 
  
 (viii) the transfer of the Contract Shares from STT to the
Selling Stockholder and the sale of the Contract Shares by the Selling Stockholder are not prompted by any material non-public information concerning Equinix which is not set forth in the Equinix Final Prospectus; and

such offer, sale, pledge, 

 disposition or filing, without the prior written consent of the Representative, except that Equinix shall not be

which shall, likewise, terminate or expire no later than the expiration of the Lock-Up Period; and, to the extent required by applicable law or stock market listing requirements, Equinix may publicly disclose the intention to cause such an issuance
of securities. 
  
 (b) the Lock-Up Period will commence on the
date hereof and will continue and include the date 45 days after the date of the Equinix Final Prospectus or such earlier date that the Representative consents to in writing; provided, however, that if (i) during the last 17 days
of the Lock-Up Period, Equinix releases earnings results or material news or a material event relating to Equinix occurs, or (ii) prior to the expiration of the Lock-Up Period, Equinix announces that it will release earnings results during the

news or material event, as applicable, unless the Representative waives, in writing, such extension (such initial period, and such initial period as extended as set forth above, as the case may be, the “Lock-Up Period”). Equinix

 3. Additional Conditions to the Obligations of the Underwriters. In addition to the conditions to the obligations of
the Underwriters to purchase the SAILS that are set forth in Part B of this Agreement, the obligations of the several Underwriters to purchase and pay for the SAILS on the Closing Date will be subject to (1) the condition that the Equinix
Registration Statement shall have been effective not later than 4:00 P.M. (New York City time), on the date hereof, (2) the accuracy of the representations and warranties on the part of Equinix and the Selling Stockholder herein, in each case
as of and on the date hereof and such Closing Date, (3) the accuracy of the statements of Equinix officers made pursuant to the provisions hereof, (4) the performance by Equinix and the Selling Stockholder of their obligations hereunder

rating of Equinix (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating); (ii) change in U.S. or international financial, political or economic conditions or

dealings in the secondary market; (iii) change, or any development involving a prospective change, in the condition (financial or other), business, properties or results of operations of Equinix and its subsidiaries, taken as a whole, from that
set forth in the Equinix Final Prospectus (exclusive of any amendments or supplements thereto subsequent to the date of this Agreement) which, in the judgment of the Representative, is material and adverse and makes it impractical or inadvisable to

law, sent or given by or on behalf of such Underwriter to such person, and if (and only to the extent that) Equinix Final Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or

Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each
case to the extent, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information relating to the Selling Stockholder or STT and
furnished to Equinix by the Selling Stockholder specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred. Notwithstanding anything to the contrary contained herein, the maximum aggregate liability of the Selling Stockholder under this Section 5(b) shall not exceed (i) the “Purchase

material fact contained in Equinix Registration Statement, any Equinix Preliminary Prospectus and the Equinix Final Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information furnished to Equinix by such Underwriter through the Representative specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by
Equinix and the Selling Stockholder in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred. 
  
 (d) Promptly after receipt by an indemnified party (the “Indemnified Party”) under this Section 5 of
notice of the commencement of any action, such Indemnified Party will, if a claim in respect thereof is to be made against an indemnifying party (the “Indemnifying Party”) under subsection (a), (b) or (c) above, notify the
Indemnifying Party of the commencement thereof; but the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been
materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have to an Indemnified Party
otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any Indemnified Party and it notifies an Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to
participate therein and, to the extent that it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense thereof, with counsel satisfactory to such Indemnified Party (who shall not, except with the consent of the
Indemnified Party, be counsel to the Indemnifying Party), and after notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense thereof, the Indemnifying Party will not be liable to such Indemnified Party
under this Section 5 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, effect any settlement of any pending or threatened action in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party unless such
settlement (i) includes an unconditional release of such Indemnified Party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a
failure to act by or on behalf of an Indemnified Party. 
  
 (e) If
the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an Indemnified Party under subsection (a), (b) or (c) above, then each Indemnifying Party shall contribute to the amount paid or
payable by such Indemnified Party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by Equinix
and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the SAILS or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also the relative fault of Equinix and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by Equinix and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from the sale of the Contract Shares (before deducting expenses) received by the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters from
the sale of the SAILS. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue 

 
statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by Equinix, the Selling Stockholder
or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an Indemnified Party as a result of the losses, claims, damages
or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim which
is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the SAILS underwritten by it and
distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this
subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. 
  
 (f) The obligations of Equinix and the Selling Stockholder under this Section 5 shall be in addition to any liability which Equinix and the Selling
Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each Underwriter, its partners, members, directors, officers and its affiliates and each person, if any, who controls any Underwriter within the meaning of the
Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section 5 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to
the Company, its directors and officers and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act and the Selling Stockholder, its affiliates, directors and officers and each person, if any, who
controls the Selling Stockholder within the meaning of the Securities Act or the Exchange Act. 
  
 6. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Selling Stockholder, of Equinix or its officers and of the
several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Selling Stockholder,
Equinix or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Contract Shares under the Forward Purchase Agreement and of the SAILS under this Agreement. If this
Agreement is terminated or if for any reason the purchase of the Contract Shares by CSFB Capital and the purchase of the SAILS by the Underwriters are not consummated, the respective obligations of Equinix, the Selling Stockholder, and the
Underwriters pursuant to Section 4(b) and Section 9 shall remain in effect.

 (a) the purchase and sale of the Contract Shares pursuant to

by and among CSFB USA and the Underwriters; 
  
 (b) in connection therewith, and with the process leading to such transaction, CSFB Capital and each Underwriter is acting solely as a principal and not the agent or fiduciary of either Equinix or the Selling Stockholder; 
  
 (c) no Underwriter has assumed an advisory or fiduciary
responsibility in favour of either Equinix or the Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising Equinix, the Selling
Stockholder or STT on other matters) or any other obligation to either Equinix or the Selling Stockholder (except the obligations expressly set forth in this Agreement or the Secondary Underwriting Agreement); and 
  
 (d) Equinix and the Seller Stockholder have each consulted
their own legal and financial advisors to the extent they deemed appropriate. Equinix and the Selling Stockholder agree they will not claim that CSFB Capital or the Underwriters, or any of them, have rendered advisory services of any nature or
respect, or owe a fiduciary or similar duty to Equinix or the Selling Stockholder Entities, in connection with such transaction or the process leading thereto. 

 14. Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York, without regard to principles of conflicts of laws. The parties hereto submit to the non-exclusive jurisdiction of the federal and state courts in the Borough of Manhattan in The City of New York in

 of the
several Underwriters for the SAILS Offering (as defined below) 
 Eleven Madison Avenue 
 New York, New York 10010-3629 
  
 Dear Sirs and Mesdames: 
  
 REFERENCE IS HEREBY MADE to (a) that certain Underwriting Agreement (the “Underwriting Agreement”), to which the Shares Offering
Representatives, as representatives of the several underwriters named or to be named on SCHEDULE A thereto (the “Shares Underwriters”), are or expect to become parties along with Equinix, Inc., a Delaware corporation (the
“Company”), and i-STT Investments Pte. Ltd., a corporation organized under the laws of the Republic of Singapore (the “Selling Stockholder”) and (b) that certain Terms Agreement (the “Terms
Agreement”) to which the SAILS Offering Representative, as representative of the several underwriters named or to be named on SCHEDULE A thereto (the “SAILS Underwriters”), are or expect to become parties along
with the Company, i-STT Investments (Bermuda) Ltd., a Bermuda corporation, and Credit Suisse First Boston (USA), Inc., a Delaware corporation. The offering of common stock of the Company (the “Common Stock”) to be made pursuant to
the Underwriting Agreement is referred to herein as the “Shares Offering” and the offering of notes exchangeable into Common Stock to be made pursuant to the Terms Agreement is referred to herein as the “SAILS
Offering.” Except as otherwise set forth herein, all capitalized terms used but not defined herein shall be ascribed the meanings assigned to such terms in the Underwriting Agreement or the Terms Agreement, as the case may be. 

 
 As an inducement to the Shares Underwriters to execute the Underwriting
Agreement, pursuant to which an offering will be made that is intended to result in an orderly market for Common Stock, and as an inducement to the SAILS Underwriters to execute the Terms Agreement, pursuant to which an offering will be made that is
intended to result in an orderly market for securities exchangeable for Common Stock, the undersigned hereby agrees that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer,
sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Common Stock or securities convertible into or exchangeable or exercisable for any Common Stock, enter into a transaction which would have the same effect, or enter
into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic 

 consequences of ownership of any Common Stock, whether any such aforementioned transaction is to be settled by delivery
of the Common Stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each
case, the prior written consent of both the Shares Offering Representatives and the SAILS Offering Representative. In addition, the undersigned agrees that, without the prior written consent of both the Shares Offering Representatives and the SAILS
Offering Representative, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for any Common Stock.

  
 The Lock-Up Period will commence on the date of the
preliminary prospectus supplement of the Company relating to the Shares Offering or, if earlier, the date of the preliminary prospectus supplement of the Company to be used in connection with the SAILS Offering, and will continue until and include
the date 45 days after the date of the final prospectus supplement of the Company relating to the Shares Offering or, if later, the date of the final prospectus supplement of the Company to be used in connection with the SAILS Offering, or such
earlier date that both the Shares Offering Representatives and the SAILS Offering Representative consent to in writing; provided, however, that if (1) during the last 17 days of the Lock-Up Period, the Company releases earnings results or
material news or a material event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up
Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless both the
Shares Offering Representatives and the SAILS Offering Representative waive, in writing, such extension (such initial period, and such initial period as extended as set forth above, as the case may be, the “Lock Up Period”).

  
 The undersigned hereby acknowledges and agrees that written
notice of any extension of the Lock-Up Period pursuant to the immediately preceding paragraph (which shall include information on when the Lock-Up Period is expected to expire pursuant to such extension) will be delivered by the Shares Offering
Representatives or the SAILS Offering Representative to the Company and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any
transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the Lock-Up Period, it will give notice
thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as may have been extended pursuant to the previous paragraph) has expired.

  
 Any Common Stock received upon exercise of options granted to
the undersigned will also be subject to this Lock-Up Agreement. Any Common Stock acquired by the undersigned in the open market after the date of the final prospectus supplement of the Company relating to the Shares Offering or, if later, the date
of the final prospectus supplement of the Company to be used in connection with the SAILS Offering, will not be subject to this Lock-Up Agreement. A transfer of Common Stock to a family member or trust may be made, provided the transferee agrees to
be bound in writing by the terms of this Lock-Up Agreement prior to such transfer and no filing by any party (donor, donee, transferor or transferee) under the Securities Act shall be required or shall be voluntarily made in connection with such
transfer (other than a filing on a Form 5 made after the expiration of the Lock-Up Period). In the event that the undersigned is an officer of the Company, the programmatic sales on behalf of the undersigned under any 10b5-1 sales plan in existence
prior to the date of this Lock-Up Agreement (a true and correct copy of which has been provided to the Shares Offering Representatives and the SAILS Offering Representative) will not be subject to this Lock-Up Agreement. 
  
 In furtherance of the foregoing, the Company and its transfer agent and
registrar are hereby authorized to decline to make any transfer of Common Stock if such transfer would constitute a violation or breach of this Lock-Up Agreement 
  
 This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns
of the undersigned. This Lock-Up Agreement shall lapse and become null and void if (i) neither the Underwriting Agreement nor the Terms Agreement shall have been executed on or before February 28, 2006, (ii) before February 28,
2006, the Selling Stockholder notifies the Company, the Shares Offering 

 Representatives and the SAILS Offering Representative in writing that it does not intend to enter into both the
Underwriting Agreement and the Terms Agreement or (iii) to the extent it has been executed, (A) the Underwriting Agreement shall have been terminated prior to the First Closing Date (as defined therein) in accordance with its terms and
(B) the Terms Agreement shall have been terminated prior to the Closing Date (as defined therein) in accordance with its terms. This Lock-Up Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

FORM OF OPINION OF LATHAM & WATKINS LLP 
 [Which shall be subject to customary exceptions and qualifications for opinions 
 on transactions of this type] 
  
 (i) The execution and delivery of the Terms Agreement, the Forward Purchase
Agreement and the Collateral Agreement do not: 
  
 (A) violate any
federal or New York statute, rule or regulation applicable to the Selling Stockholder; 
  
 or 
  
 (B) require any consents,
approvals or authorizations to be obtained by the Selling Stockholder from, or any registrations, declarations or filings to be made by the Selling Stockholder with, any governmental authority under any federal or New York statute, rule or
regulation applicable to the Selling Stockholder that have not been obtained or made. 
  
 (ii) The Selling Stockholder is not, and immediately after giving effect to its receipt of the proceeds of the sale of the Contract Shares under the Forward Purchase Agreement and its pledge of the Contract
Shares under the Collateral Agreement, will not be required to be registered as an ”investment company” within the meaning of the Investment Company Act of 1940, as amended. 
  
 (iii) The Collateral Agreement creates a valid security interest in favor of
CSFB Capital in that portion of the collateral described in Section 1(a) of the Collateral Agreement in which the Selling Shareholder has rights and a valid security interest may be created under Article 9 of the New York UCC (the “Article
9 Collateral”). The Article 9 Collateral includes 4,300,000 shares of common stock of Equinix, Inc. 
  
 (iv) Assuming that: (i) the Collateral Account (as defined in the Collateral Agreement) is a “securities account” within the meaning of
Section 8-501 of the New York UCC, (ii) the securities intermediary’s jurisdiction with respect to the Collateral Account is the State of New York and (iii) CFSB Capital is the entitlement holder of the Collateral Account (as to
which we express no opinion), then upon crediting of that portion of the Article 9 Collateral consisting of “securities” (as defined in Section 8-102(a)(15)) to the Collateral Account the security interest of CSFB Capital in such
securities will be perfected. Section 8-103(a) of the New York UCC provides that “A share or similar equity interest issued by a corporation, business trust, joint stock company or similar entity is a security” and, accordingly, we are of
the opinion that, assuming that Equinix, Inc. has been duly organized and is validly existing as a Delaware corporation, the 4,300,000 shares of common stock of Equinix, Inc. constitutes securities for purposes of the New York UCC. 
  
 (v) The Forward Purchase Agreement and the Collateral Agreement have been
duly executed (with respect to which such opinion may rely on an officer’s certificate) and delivered by the Selling Stockholder under the law of the State of New York and, assuming that they have been validly authorized, executed and delivered
by the Selling Stockholder under the law of Bermuda and by each other party thereto, are the valid and binding agreements of the Selling Stockholder, enforceable against the Selling Stockholder in accordance with their respective terms.

 of the several Underwriters for the SAILS Offering (as defined below) 
 Eleven Madison Avenue New York, New York 10010-3629 
  
 Dear Sirs and Mesdames: 
  
 REFERENCE IS HEREBY MADE to (a) that certain Underwriting Agreement (the “Underwriting Agreement”), to which the Shares Offering
Representatives, as representatives of the several underwriters named or to be named on SCHEDULE A thereto (the “Shares Underwriters”), are or expect to become parties along with Equinix, Inc., a Delaware corporation (the
“Company”), and i-STT Investments Pte. Ltd., a corporation organized under the laws of the Republic of Singapore (the “Selling Stockholder”) and (b) that certain Terms Agreement (the “Terms
Agreement”) to which the SAILS Offering Representative, as representative of the several underwriters named or to be named on SCHEDULE A thereto (the “SAILS Underwriters”), is or expects to become a party along
with the Company, Credit Suisse First Boston (USA), Inc., a Delaware corporation, and i-STT Investments (Bermuda) Ltd., a Bermuda corporation. The offering of common stock of the Company (the “Common Stock”) to be made pursuant to
the Underwriting Agreement is referred to herein as the “Shares Offering” and the offering of securities exchangeable into Common Stock to be made pursuant to the Terms Agreement is referred to herein as the “SAILS
Offering.” Except as otherwise set forth herein, all capitalized terms used but not defined herein shall be ascribed the meanings assigned to such terms in the Underwriting Agreement or the Terms Agreement, as the case may be. 

 
 As an inducement to the Shares Underwriters to execute the Underwriting
Agreement, pursuant to which an offering will be made that is intended to result in an orderly market for Common Stock, and as an inducement to the SAILS Underwriters to execute the Terms Agreement, pursuant to which an offering will be made that is
intended to result in an orderly market for securities exchangeable into Common Stock, the undersigned hereby agrees that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer,
sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Common Stock or securities convertible into or 

 exchangeable or exercisable for any Common Stock, enter into a transaction which would have the same effect, or enter
into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of any Common Stock, whether any such aforementioned transaction is to be settled by delivery of the Common Stock or such
other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent
of the Representatives. In addition, the undersigned agrees that it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable
or exchangeable for any Common Stock. 
  
 The Lock-Up Period will
commence on the date hereof and will continue until and include the date 45 days after the date of the final prospectus supplement to be used in connection with the Shares Offering or, if later, the date of the final prospectus supplement of the
Company to be used in connection with the SAILS Offering, or such earlier date that both the Shares Offering Representatives and the SAILS Offering Representative consent to in writing; provided, however, that if (1) during the
last 17 days of the Lock-Up Period, the Company releases earnings results or material news or a material event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release
earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or
the occurrence of the material news or material event, as applicable, unless both the Shares Offering Representatives and the SAILS Offering Representative waive, in writing, such extension (such initial period, and such initial period as extended
as set forth above, as the case may be, the “Lock-Up Period”). 
  
 The undersigned hereby acknowledges and agrees that written notice of any extension of the Lock-Up Period pursuant to the immediately preceding paragraph (which shall include information on when the Lock-Up Period is
expected to expire pursuant to such extension) will be delivered by the Shares Offering Representatives and the SAILS Offering Representative to the Selling Stockholder and that any such notice properly delivered will be deemed to have been given
to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up
Agreement to and including the 34th day following the expiration of the Lock-Up Period, it will give notice thereof
to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as may have been extended pursuant to the previous paragraph) has expired.

  
 Notwithstanding the foregoing, the restrictions in the second
paragraph above shall not apply to: 
  
 (a) transactions relating
to Common Stock or other securities of the Company acquired in open market transactions after the completion of the offering of the Common Stock contemplated by the Underwriting Agreement; 
  
 (b) transfers of Common Stock or any securities convertible into Common Stock
as a bona fide gift, provided that in the case of any such transfer, each such donee shall sign and deliver a lock-up agreement substantially in the form of this Lock-Up Agreement prior to such transfer; 
  
 (c) transfers of shares of Common Stock or any securities convertible into
Common Stock to stockholders or majority-owned subsidiaries of the undersigned, provided that in the case of any such transfer, each such transferee shall sign and deliver a lock-up agreement substantially in the form of this Lock-Up
Agreement prior to such transfer; 
  
 (d) the conversion or
exercise, as applicable, of: (i) the Preferred Stock Warrant of the Company, dated December 31, 2002 (Warrant No. PS-1); (ii) shares of Series A-1 Convertible Preferred Stock, par value $0.001 per share; or (iii) the 14% Series
A-1 Convertible Secured Note Due 2007 of the Company, dated February 3, 2005 (Security No. CSN-2), the 14% Series A-1 Payment-of-Interest-In-Kind Convertible Secured Note Due 2007 of the Company, dated May 1, 2005 (Security No. PIK-A-1-5),
or the 14% Series A-1 Payment-of-Interest-In-Kind Convertible Secured Note Due 2007 of the Company, dated November 1, 2005 (Security No. PIK-A-1-6), in each case with respect to (i), (ii) and (iii), held by the Selling Stockholder at the
time of any such conversion or exercise; 

 (e) any sales, dispositions, transfers or pledges of any Common Stock pursuant to any of the following
agreements: (i) the Underwriting Agreement; (ii) the Forward Purchase Agreement entered into or expected to be entered into by and between i-STT Investments (Bermuda) Ltd. and Credit Suisse First Boston Capital LLC; (iii) the
Collateral Agreement entered into or expected to be entered into by and among i-STT Investments (Bermuda) Ltd., Credit Suisse First Boston Capital LLC and Credit Suisse First Boston LLC (the “Collateral Agreement”); or (iv) the
Terms Agreement entered into or expected to be entered into by and among i-STT Investments (Bermuda) Ltd., the Company, Credit Suisse First Boston LLC and Credit Suisse First Boston (USA), Inc., in each case with respect to (i) through
(iv) above, to which the Selling Stockholder, or any affiliate of the Selling Stockholder, as applicable, shall have become a party thereto, respectively; or 
  
 (f) any transfer or assignment of Common Stock to i-STT Investments (Bermuda) Ltd., a corporation organized under the laws
of Bermuda, in connection with, or otherwise contemplated by, the agreements referred to in clauses (ii), (iii) or (iv) of provision (e) above; provided that, in the event and to the extent that any such transferred or assigned
Common Stock is not, is not expected to become, or is no longer, subject to pledge under the Collateral Agreement during the Lock-Up Period pursuant to such aforementioned agreements, i-STT Investments (Bermuda) Ltd. shall sign and deliver a Lock-Up
Agreement substantially in the form of this Lock-Up Agreement with respect to such Common Stock. 
  
 In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of Securities if
such transfer would constitute a violation or breach of this Lock-Up Agreement. 
  
 This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Lock-Up Agreement shall lapse and become null and void if
(i) neither the Underwriting Agreement nor the Terms Agreement shall have been executed on or before February 28, 2006, (ii) before February 28, 2006, the Selling Stockholder or I-STT Investments (Bermuda) Ltd. (as applicable)
notifies the Company, the Shares Offering Representatives and the SAILS Offering Representative in writing that it does not intend to enter into both the Underwriting Agreement and the Terms Agreement or (iii) to the extent it has been
executed, (A) the Underwriting Agreement shall have been terminated prior to the First Closing Date (as defined therein) in accordance with its terms and (B) the Terms Agreement shall have been terminated prior to Closing Date (as defined

FORM OF APPLEBY SPURLING HUNTER OPINION 
  
 (9/11/05) 
  
 Our Ref: 131304.02 
  
 [16 November] 2005 
  
 Credit Suisse First Boston LLC Eleven Madison Avenue 
  
 New York 
  
 New York 10010-3629 
  
 Dear Sirs, 
  
 Re: i-STT Investments (Bermuda) Ltd. (the “Company”) 
  
 1. This opinion as to Bermuda law is addressed to you in connection with: 
  
 (a) a terms agreement dated [ ] 2005 entered into amongst Credit Suisse First Boston USA Inc., the Company, Equinix, Inc. and Credit Suisse First Boston
LLC (as “Representative” of the underwriters named therein (the “Underwriters”)); 
  
 (b) a forward purchase agreement dated [ ] 2005 entered into amongst the Company (as the “Seller”) and Credit Suisse First Boston Capital LLC
(as the “Purchaser”); and 
  
 (c) a collateral agreement
dated [ ] 2005 entered into amongst the Company (as the “Pledgor”), Credit Suisse First Boston LLC (as the “Collateral Agent”) and Credit Suisse First Boston Capital LLC (as the “Purchaser”), (collectively referred to
hereinafter as the “Documents”). 
  
 2. For the purpose of this opinion,
we have examined and relied upon the following: 
  
 (a) certified
copies of the executed Documents; 
  
 (b) copies, certified to be
true copies, of the Memorandum of Association and Bye-laws of the Company (adopted on [ ] and amended up to                     ) (collectively
referred to hereinafter as the “Constitutional Documents”); 
  
 (c) a certified copy of the written resolutions of the sole shareholder of the Company passed on [ ] and a certified copy of the written resolutions of the Board of Directors of the Company passed on [ ] (collectively referred to
hereinafter as the “Resolutions”); 
  
 (d) a
Director’s Certificate dated [             (the “Certificate”) confirming certain matters of fact and opinion; 

 (e) the entries and filings shown in respect of the Company on the file of the Company maintained at the
offices of the Registrar of Companies; and the entries and filings shown in respect of the Company in the Supreme Court Causes Book and Register of Judgements maintained at the Registry of the Supreme Court of Bermuda. 
  
 The searches referred to in paragraphs 2(e) and 2(f) were conducted on and completed at
[             ] Bermuda time and updated on [             and completed at [ ], Bermuda time. 
  
 [Our search referred to in paragraph 2(e) above revealed [ ] chargeXs registered against the
Company, the details of which have been provided to you separately. We have not conducted any investigation into the documents relating to the chargeXs.] 
  
 3. We have made no investigation of, and express no opinion as to, the laws of any jurisdiction other than Bermuda. 
  
 4. We have assumed: 
  
 (a) that the Documents are valid, binding and enforceable under the laws of the State of New York, United States of America
(“New York”) by which they are expressed to be governed; 
  
 (b) the capacity, power and authority of all parties other than the Company to enter into and to perform their respective obligations under the Documents; 
  
 (c) the conformity to original documents of all documents produced to us as copies and the authenticity of all original
documents, which or copies of which have been submitted to us; 
  
 (d) the genuineness of all signatures, seals and chops (if any) on the Documents and all other documents which we have examined; 
  
 (e) the accuracy and completeness of all factual representations, warranties or statements of fact or law, other than as to the laws of Bermuda, made in
any of the documents examined by us; 
  
 (f) that there have been
no amendments to the Memorandum of Association or Bye-laws of the Company other than as referred to above; 
  
 (g) that the Resolutions are a full and accurate record of resolutions duly passed by the sole shareholder or Directors of the Company (as the case may
be) and that the Resolutions have not been amended or rescinded and are in full force and effect and that there is no matter affecting the authority of the Directors of the Company to enter into the Documents, not disclosed by the Constitutional
Documents or the Resolutions, which would have any adverse implication in relation to the opinions expressed herein; that the Company is not carrying on investment business in or from within Bermuda under the provisions of the Investment Business
Act 2003 as amended from time to time (the “IBA”); 

 (h) that the Documents have been duly authorised, executed and delivered by the parties thereto other
than the Company, and the performance thereof is within the capacity and powers of each such party thereto other than the Company, that the Documents constitute legal, valid and binding obligations of each such party other than the Company and that
each such party to which the Company purportedly delivered the Documents has actually received and accepted delivery of such Documents; 
  
 (i) that the information disclosed by our searches has not been materially altered and that the searches did not fail to disclose any information material
for the purposes of this opinion which had been lodged for filing or registration or should have been delivered for filing or registration, but was not disclosed or did not appear on the public file or register at the time of the searches;

  
 (j) that each of the Documents and other such documentation
which was received by electronic means is complete, intact and in conformity with the transmission as sent; 
  
 (k) that the [Underwriters, the Representative, the Purchaser and the Collateral Agent] have no express or constructive knowledge of any circumstance
whereby any Director of the Company, when the Board of Directors of the 
  
 (l) Company [ passed / adopted the Resolutions, failed to discharge his fiduciary duty owed to the Company and to act honestly and in good faith with a view to the best interests of the Company; and 
  
 (m) that there are no circumstances affecting the enforceability of the
Documents which have arisen since the date of execution of the respective Documents, of which we are unaware, which would have any adverse implication in relation to the opinions expressed herein. 
  
 5. Based on the foregoing and subject to the reservations set out below and subject to any
matter not disclosed to us, we are of the opinion that: 
  
 (a)
The Company is a limited liability company, duly incorporated and validly existing under the laws of Bermuda, possessing perpetual corporate existence with the capacity to sue and be sued in its own name. No steps have been taken or are being taken
to appoint a liquidator over or to wind up the Company and to the best of our knowledge no steps have been or are being taken to appoint a receiver. 
  
 (b) The Company has the necessary corporate capacity and power to enter into and to perform its obligations under the Documents and the transactions
contemplated thereby and the Company has taken all necessary corporate and other action to authorise the entry into and performance of the Documents and the transactions contemplated thereby. 
  
 (c) The obligations of the Company as set out in the Documents constitute
valid and legally binding obligations of the Company enforceable in accordance with the terms of the Documents and would be so treated in the courts of Bermuda. The Documents are in proper form for enforcement in such courts. 

 (d) The Company having been designated as non-resident for the purposes of the Exchange Control Act,
1972, it is not necessary for the consent of, licence from, or exemption by any governmental or administrative body or authority of Bermuda to be obtained to enable the Company to enter into and perform its obligations as set out in the Documents.

  
 (e) The execution and delivery of, the performance of the
obligations under, and compliance with the relevant provisions of the Documents by the Company will not (i) contravene any existing applicable law, statute, rule or regulation of Bermuda or any judgment, decree or permit of Bermuda to which the
Company is subject, (ii) contravene or conflict with any provision of the Company’s Memorandum of Association and Bye-laws; (iii) contravene any provision of any kind under Bermuda law imposing a limit upon borrowings or the giving of
guarantees by the Company, or upon the powers of the Company’s Directors to borrow or to grant such guarantees; or (iv) based on a review of the Certificate, contravene any material agreement or other instrument binding upon the Company or
to which any of the property or assets of the Company are subject. 
  
 (f) Subject to paragraph 5(g) and any filings or registrations with respect to enforcement of judgment proceedings in the Supreme Court of Bermuda, to ensure the validity and enforceability of the Documents in Bermuda, it is not necessary
that they be registered in any register kept by, or filed with, or recorded or notarised in any governmental authority or regulatory body in Bermuda, or that any other instrument relating thereto be signed, delivered, filed, registered or recorded
or that any tax or duty be paid or any other action whatever be taken in Bermuda. 
  
 (g) To the extent that the Documents create or result in the creation of a charge over the assets of the Company under the governing law of the Documents, such charge is, or will become, registerable in Bermuda under
Part V of the Companies Act, 1981 upon payment of a registration fee. Registration is not compulsory and there is no time limit within which registration must be effected. However, in the event that questions of priority fall to be determined by
reference to Bermuda law, any charge registered will have priority based on the date that it is registered and not on the date of its creation. 
  
 (h) Subject to paragraph 5(g) and any filings or registrations with respect to enforcement of judgment proceedings in the Supreme Court of Bermuda, all
authorizations, approvals, consents, licences, exemptions, filings, registrations, notarisation and other requirements of governmental, judicial and public bodies and authorities of or in Bermuda required or advisable in connection with the entry
into, performance, validity and enforceability of the Documents and the transactions contemplated thereby have been obtained or effected and are in full force and effect. 
  
 (i) Based solely upon the searches undertaken in paragraphs 2(e) and (0 above: 
  
 (i) no litigation, administrative or other proceeding of or before any
governmental authority of Bermuda is pending against or affecting the Company; and 
  
 (ii) no notice to the Registrar of Companies of the passing of a resolution of members or creditors to wind up or the appointment of a liquidator or receiver has been given. No petition 

 to wind up the Company or application to reorganise its affairs pursuant to a Scheme of Arrangement or application for
the appointment of a receiver has been filed with the Supreme Court. 
  
 6. Our
reservations are as follows: 
  
 (a) We express no opinion as to
whether specific performance or injunctive relief, being equitable remedies, would necessarily be available in respect of any of the obligations of the Company under the Documents. In particular, we express no opinion as to the enforceability of any
present or future waiver of any provision of law (whether substantive or procedural) or of any right or remedy which might otherwise be available presently or in the future under the Documents. 
  
 (b) The obligations of the Company under the Documents will be subject to any
laws from time to time in effect relating to bankruptcy or liquidation or any other laws or other legal procedures affecting generally the enforcement of creditors’ rights and may also be the subject of a statutory limitation of the time within
which proceedings may be brought. Without prejudice to the generality of the foregoing, we express no opinion as to whether any contractual right of set-off contained in the respective Documents will conflict with the statutory right of set-off
applicable in an insolvent winding up of the Company. 
  
 (c)
Where an obligation is to be performed in a jurisdiction other than Bermuda, the courts of Bermuda may refuse to enforce it to the extent that such performance would be illegal under the laws of or contrary to the public policy of such other
jurisdiction. 
  
 (d) Any provision to the effect that certain
calculations or certificates will be conclusive and binding upon the parties will not necessarily be effective if such calculations or certificates are fraudulent or erroneous on their face and will not necessarily prevent judicial enquiry into the
merits of any claim by an aggrieved party. 
  
 (e) To the extent
that any provisions of the Documents require the payment by the Company of a higher rate of interest on overdue amounts than on amounts which are current, we express no opinion as to the validity or the binding effect thereof. A Bermuda court, even
if it were applying the laws of another jurisdiction, might not give effect to such a provision if it could be established that the amount expressed as being payable was in the nature of a penalty, that is to say, a requirement for a stipulated sum
to be paid irrespective of, or necessarily greater than, the loss likely to be sustained. 
  
 (f) Section 9 of the Interest and Credit Charges (Regulation) Act 1975 provides that the Bermuda courts have discretion as to the amount of interest if any payable on the amount of a judgment after the date of
judgment. If the court does not exercise that discretion, then interest will be paid at the statutory rate which is currently seven per cent per annum. 
  
 (g) We express no opinion as to the validity or binding effect of any provision in the Documents which provides for the severance of illegal, invalid or
unenforceable provisions. 
  
 (h) The term “enforceable”
as used in this opinion means there is a way of ensuring that each party performs an agreement or that there are remedies available for breach. 

 (i) We have relied upon statements and representations made to us in the Certificate provided to us by a
director of the Company for the purposes of this opinion. We have made no independent verification of the matters referred to in the Certificate, and we qualify our opinion to the extent that the statements or representations made in the Certificate
are not accurate in any respect. 
  
 The searches
referred to in paragraphs 2(e) and (f) are not conclusive and do not reveal: 
  
 (i) details of matters which have been lodged for filing or registration which as a matter of best practice of the Registrar of Companies or the Registry of the Supreme Court would have or should have been disclosed
on the public file, the Causes Book or the Judgment Book, as the case may be, but for whatever reason have not actually been filed or registered or are not disclosed or which, notwithstanding filing or registration, at the date and time the search
is concluded are for whatever reason not disclosed or do not appear on the public file, the Causes Book or Judgment Book; 
  
 (ii) details of matters which should have been lodged for filing or registration at the Registrar of Companies or the Registry of the Supreme Court but
have not been lodged for filing or registration at the date the search is concluded; 
  
 (iii) whether an application to the Supreme Court for a winding-up petition or for the appointment of a receiver or manager has been prepared but not yet been presented or has been presented but does not appear in the
Causes Book at the date and time the search is concluded; 
  
 (iv)
whether arbitration or administrative proceedings are pending or whether any proceedings are threatened, or whether any arbitrator has been appointed; or 
  
 (v) whether a receiver or manager has been appointed privately pursuant to the provisions of a debenture or other security, unless notice of the fact has
been entered in the Register of Charges in accordance with the provisions of the Companies Act, 1981. 
  
 Furthermore, in the absence of a statutorily defined system for the registration of charges created by companies incorporated outside Bermuda (“overseas companies”) over their assets located in Bermuda, it
is not possible to determine definitively from searches of the Register of Charges maintained by the Registrar of Companies in respect of such overseas companies what charges have been registered over any of their assets located in Bermuda or

 1. Introductory. Credit Suisse First Boston (USA), Inc., a Delaware
corporation (“Company”), proposes to issue and sell from time to time certain of its unsecured debt securities registered under the registration statement referred to in Section 2(a) (“Registered Securities”).
The Registered Securities will be issued under an indenture, dated as of June 1, 2001 (“Indenture”), between the Company and The Chase Manhattan Bank, as Trustee, in one or more series, which series may vary as to interest
rates, maturities, redemption provisions, selling prices and other terms. Particular series or offerings of Registered Securities will be sold pursuant to a Terms Agreement referred to in Section 3, for resale in accordance with terms of
offering determined at the time of sale. 
  
 The Registered
Securities involved in any such offering are hereinafter referred to as the “Offered Securities”. The firm or firms which agree to purchase the Offered Securities are hereinafter referred to as the “Underwriters” of
such securities, and the representative or representatives of the Underwriters, if any, specified in a Terms Agreement referred to in Section 3 are hereinafter referred to as the “Representatives”; provided, however, that if
the Terms Agreement does not specify any representative of the Underwriters, the term “Representatives”, as used in this Agreement (other than in Sections 2(b), 5(c) and 6 and the second sentence of Section 3), shall mean
the Underwriters. 
  
 2. Representations and Warranties of the
Company. The Company, as of the date of each Terms Agreement referred to in Section 3, represents and warrants to, and agrees with, each Underwriter that:

Securities has been filed with the Securities and Exchange Commission (“Commission”) and has become effective. Such registration statement, as amended at the time of any Terms Agreement referred to in Section 3, is hereinafter
referred to as the “Registration Statement”, and the prospectus included in such Registration Statement, as supplemented as contemplated by Section 3 to reflect the terms of the Offered Securities and the terms of the offering
of the Offered Securities, as first filed with the Commission pursuant to and in accordance with Rule 424(b) (“Rule 424(b)”) under the Securities Act of 1933 (“Act”), including all material incorporated by
reference therein, is hereinafter referred to as the “Prospectus”. No document has been or will be prepared or distributed in reliance on Rule 434 under the Act. 
  
 (b) On the effective date of the registration statement relating to the Registered Securities, such
registration statement conformed in all respects to the requirements of the Act, the Trust Indenture Act of 1939 (“Trust Indenture Act”) and the rules and regulations of the Commission (“Rules and Regulations”) and
did not include any 

 
untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not
misleading, and on the date of each Terms Agreement referred to in Section 3, the Registration Statement and the Prospectus will conform in all respects to the requirements of the Act, the Trust Indenture Act and the Rules and Regulations, and
neither of such documents will include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, except that the foregoing does not apply to

existing corporation in good standing under the laws of the State of Delaware, with power and authority (corporate and other) to own its properties and conduct its business as described in the Prospectus; and the Company is duly qualified to do

standing under the laws of the jurisdiction of its incorporation, with power and authority (corporate and other) to own its properties and conduct its business as described in the Prospectus; and each subsidiary of the Company is duly qualified to

or pursuant to Delayed Delivery Contracts (as hereinafter defined), the Indenture will have been duly executed and delivered, such Offered Securities will have been duly executed, authenticated, issued and delivered and will conform to the
description thereof contained in the Prospectus and the Indenture and such Offered Securities will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency,

 (f) No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any

obtained and made under the Act and the Trust Indenture Act and such as may be required under state securities laws. 
  

 2 

 (g) The execution, delivery and performance of the Indenture, the Terms Agreement
(including the provisions of this Agreement) and any Delayed Delivery Contracts and the issuance and sale of the Offered Securities and compliance with the terms and provisions thereof will not result in a breach or violation of any of the terms and
provisions of, or constitute a default under, any statute, any rule, regulation or order of any governmental agency or body or any court, domestic or foreign, having jurisdiction over the Company or any subsidiary of the Company or any of their
properties, or any agreement or instrument to which the Company or any such subsidiary is a party or by which the Company or any such subsidiary is bound or to which any of the properties of the Company or any such subsidiary is subject, or the
charter or by-laws of the Company or any such subsidiary, and the Company has full power and authority to authorize, issue and sell the Offered Securities as contemplated by the Terms Agreement (including the provisions of this Agreement).

  
 (h) The Terms Agreement (including the
provisions of this Agreement) and any Delayed Delivery Contracts have been duly authorized, executed and delivered by the Company. 
  
 (i) Except as disclosed in the Prospectus, the Company and its subsidiaries have good and marketable title to all real properties and all
other properties and assets owned by them, in each case free from liens, encumbrances and defects that would materially affect the value thereof or materially interfere with the use made or to be made thereof by them; and except as disclosed in the
Prospectus, the Company and its subsidiaries hold any leased real or personal property under valid and enforceable leases with no exceptions that would materially interfere with the use made or to be made thereof by them. 
  
 (j) The Company and its subsidiaries possess adequate
certificates, authorities or permits issued by appropriate governmental agencies or bodies necessary to conduct the business now operated by them and have not received any notice of proceedings relating to the revocation or modification of any such
certificate, authority or permit that, if determined adversely to the Company or any of its subsidiaries, would individually or in the aggregate have a material adverse effect on the condition (financial or other), business, properties or results of
operations of the Company and its subsidiaries taken as a whole (“Material Adverse Effect”). 
  
 (k) No labor dispute with the employees of the Company or any subsidiary exists or, to the knowledge of the Company, is imminent that
might have a Material Adverse Effect. 
  
 (l) The
Company and its subsidiaries own, possess or can acquire on reasonable terms, adequate trademarks, trade names and other rights to inventions, know-how, patents, copyrights, confidential information and other intellectual property (collectively,
“intellectual property rights”) necessary to conduct the business now operated by them, or presently employed by them, and have not received any notice of infringement of or conflict with asserted rights of others with respect to
any intellectual 

  

 3 

 
property rights that, if determined adversely to the Company or any of its subsidiaries, would individually or in the aggregate have a Material Adverse
Effect. 
  
 (m) Except as disclosed in the
Prospectus, there are no pending actions, suits or proceedings against or affecting the Company, any of its subsidiaries or any of their respective properties that, if determined adversely to the Company or any of its subsidiaries, would
individually or in the aggregate have a Material Adverse Effect, or would materially and adversely affect the ability of the Company to perform its obligations under the Indenture, the Terms Agreement (including the provisions of this Agreement) or
any Delayed Delivery Contracts, or which are otherwise material in the context of the sale of the Offered Securities; and no such actions, suits or proceedings are threatened or, to the Company’s knowledge, contemplated. 
  
 (n) The financial statements included in the Registration
Statement and Prospectus present fairly the financial position of the Company and its consolidated subsidiaries as of the dates shown and their results of operations and cash flows for the periods shown, and, except as otherwise disclosed in the
Prospectus, such financial statements have been prepared in conformity with the generally accepted accounting principles in the United States applied on a consistent basis; any schedules included in the Registration Statement present fairly the
information required to be stated therein; and if pro forma financial statements are included in the Registration Statement and Prospectus: the assumptions used in preparing the pro forma financial statements included in the Registration Statement
and the Prospectus provide a reasonable basis for presenting the significant effects directly attributable to the transactions or events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro
forma columns therein reflect the proper application of those adjustments to the corresponding historical financial statement amounts. 
  
 (o) Except as disclosed in the Prospectus, since the date of the latest audited financial statements included in the Prospectus there has
been no material adverse change, nor any development or event involving a prospective material adverse change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as a whole,
and, except as disclosed in or contemplated by the Prospectus, there has been no dividend or distribution of any kind declared, paid or made by the Company on any class of its capital stock. 
  
 (p) The Company is not and, after giving effect to the
offering and sale of the Offered Securities and the application of the proceeds thereof as described in the Prospectus, will not be an “investment company” as defined in the Investment Company Act of 1940. 
  
 3. Purchase and Offering of Offered Securities. The obligation of the
Underwriters to purchase the Offered Securities will be evidenced by an agreement or exchange of other written communications (“Terms Agreement”) at the time the Company determines to sell the Offered Securities. The Terms Agreement
will incorporate by reference the provisions of this Agreement, except as otherwise provided therein, and will specify the firm or firms which will be Underwriters, the names of any Representatives, the principal amount to be purchased by each

  

 4 

 
Underwriter, the purchase price to be paid by the Underwriters and the terms of the Offered Securities not already specified in the Indenture, including, but
not limited to, interest rate, maturity, any redemption provisions and any sinking fund requirements and whether any of the Offered Securities may be sold to institutional investors pursuant to Delayed Delivery Contracts. The Terms Agreement will
also specify the time and date of delivery and payment (such time and date, or such other time not later than seven full business days thereafter as the Underwriter first named in the Terms Agreement (the “Lead Underwriter”) and the
Company agree as the time for payment and delivery, being herein and in the Terms Agreement referred to as the “Closing Date”), the place of delivery and payment and any details of the terms of offering that should be reflected in
the prospectus supplement relating to the offering of the Offered Securities. For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the Closing Date (if later than the otherwise applicable settlement date) shall be the date for
payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering, other than Contract Securities for which payment of funds and delivery of securities shall be as hereinafter provided. The obligations of the
Underwriters to purchase the Offered Securities will be several and not joint. It is understood that the Underwriters propose to offer the Offered Securities for sale as set forth in the Prospectus. 
  
 If the Terms Agreement provides for sales of Offered Securities pursuant to
delayed delivery contracts, the Company authorizes the Underwriters to solicit offers to purchase Offered Securities pursuant to delayed delivery contracts substantially in the form of Annex I attached hereto (“Delayed Delivery
Contracts”) with such changes therein as the Company may authorize or approve. Delayed Delivery Contracts are to be with institutional investors, including commercial and savings banks, insurance companies, pension funds, investment
companies and educational and charitable institutions. On the Closing Date the Company will pay, as compensation, to the Representatives for the accounts of the Underwriters, the fee set forth in such Terms Agreement in respect of the principal
amount of Offered Securities to be sold pursuant to Delayed Delivery Contracts (“Contract Securities”). The Underwriters will not have any responsibility in respect of the validity or the performance of Delayed Delivery Contracts.
If the Company executes and delivers Delayed Delivery Contracts, the Contract Securities will be deducted from the Offered Securities to be purchased by the several Underwriters and the aggregate principal amount of Offered Securities to be
purchased by each Underwriter will be reduced pro rata in proportion to the principal amount of Offered Securities set forth opposite each Underwriter’s name in such Terms Agreement, except to the extent that the Lead Underwriter determines
that such reduction shall be otherwise than pro rata and so advise the Company. The Company will advise the Lead Underwriter not later than the business day prior to the Closing Date of the principal amount of Contract Securities. 
  
 The Offered Securities delivered to the Underwriters on the Closing Date will
be in definitive fully registered form in such denominations and registered in such names as the Lead Underwriter requests. 
  
 If the Terms Agreement specifies “Book-Entry Only” settlement or otherwise states that the provisions of this paragraph shall apply, the Company
will deliver against payment of the purchase price the Offered Securities in the form of one or more permanent global securities in definitive form (the “Global Securities”) deposited with the Trustee as custodian for The Depository
Trust Company (“DTC”) and registered in the name of Cede & Co., as nominee for 

  

 5 

 
DTC. Interests in any permanent global securities will be held only in book-entry form through DTC, except in the limited circumstances described in the
Prospectus. Payment for the Offered Securities shall be made by the Underwriters in Federal (same day) funds by official check or checks or wire transfer to an account previously designated by the Company at a bank acceptable to the Lead
Underwriter, in each case drawn to the order of Credit Suisse First Boston (USA), Inc. at the place of payment specified in the Terms Agreement on the Closing Date, against delivery to the Trustee as custodian for DTC of the Global Securities
representing all of the Offered Securities. 
  
 4. Certain
Agreements of the Company. The Company agrees with the several Underwriters that it will furnish to counsel for the Underwriters, one signed copy of the registration statement relating to the Registered Securities, including all exhibits, in the

 (b) The Company will advise the Lead Underwriter promptly of any proposal to amend or supplement the
Registration Statement or the Prospectus and will afford the Lead Underwriter a reasonable opportunity to comment on any such proposed amendment or supplement; and the Company will also advise the Lead Underwriter promptly of the filing of any such
amendment or supplement and of the institution by the Commission of any stop order proceedings in respect of the Registration Statement or of any part thereof and will use its best efforts to prevent the issuance of any such stop order and to obtain
as soon as possible its lifting, if issued. 
  
 (c) If, at any time when a prospectus relating to the Offered Securities is required to be delivered under the Act in connection with sales by any Underwriter or dealer, any event occurs as a result of which the Prospectus as then amended
or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at
any time to amend the Prospectus to comply with the Act, the Company promptly will notify the Lead Underwriter of such event and will promptly prepare and file with the Commission, at its own expense, an amendment or supplement which will correct
such statement or omission or an amendment which will effect such compliance. Neither the Lead Underwriter’s consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions
set forth in Section 5 hereof. 
  
 (d) As
soon as practicable, but not later than 16 months, after the date of each Terms Agreement, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the

prospectus, any related preliminary prospectus supplement, the Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Lead Underwriter reasonably requests. The Company will
pay the expenses of printing and distributing to the Underwriters all such documents. 
  
 (f) The Company will arrange for the qualification of the Offered Securities for sale and the determination of their eligibility for
investment under the laws of such jurisdictions as the Lead Underwriter designates and will continue such qualifications in effect so long as required for the distribution. 
  
 (g) During the period of five years after the date of any Terms Agreement, the Company will furnish to the
Representatives and, upon request, to each of the other Underwriters, if any, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year, if any; and the Company will furnish to the
Representatives (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Securities Exchange Act of 1934 or mailed to stockholders, if any, and (ii) from time to
time, such other information concerning the Company as the Lead Underwriter may reasonably request. 
  
 (h) The Company will pay all expenses incident to the performance of its obligations under the Terms Agreement (including the provisions
of this Agreement), for any filing fees or other expenses (including fees and disbursements of counsel) in connection with qualification of the Registered Securities for sale and any determination of their eligibility for investment under the laws
of such jurisdictions as the Lead Underwriter may designate and the printing of memoranda relating thereto, for any fees charged by investment rating agencies for the rating of the Offered Securities, for any applicable filing fee incident to, the
review by the National Association of Securities Dealers, Inc. of the Registered Securities, for any travel expenses of the Company’s officers and employees and any other expenses of the Company in connection with attending or hosting meetings
with prospective purchasers of Registered Securities and for expenses incurred in distributing the Prospectus, any preliminary prospectuses, any preliminary prospectus supplements or any other amendments or supplements to the Prospectus to the
Underwriters. 
  
 (i) The Company will not offer,
sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Act relating to United States dollar-denominated debt securities issued or guaranteed by the Company and
having a maturity of more than one year from the date of issue, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the Lead Underwriter for a period beginning 

  

 7 

 
at the time of execution of the Terms Agreement and ending the number of days after the Closing Date specified under “Blackout” in the Terms
Agreement. 
  
 5. Conditions of the Obligations of the
Underwriters. The obligations of the several Underwriters to purchase and pay for the Offered Securities will be subject to the accuracy of the representations and warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent: 
  
 (a) On or prior to the date of the Terms Agreement, the Representatives shall have received a letter, dated
the date of delivery thereof, of KMPG LLP confirming that they are independent public accountants within the meaning of the Act and the applicable published Rules and Regulations thereunder and stating to the effect that: 
  
 (i) in their opinion the financial statements and any
schedules and any summary of earnings examined by them and included in the Prospectus comply as to form in all material respects with the applicable accounting requirements of the Act and the related published Rules and Regulations; 
  
 (ii) they have performed the procedures specified by the
American Institute of Certified Public Accountants for a review of interim financial information as described in Statement of Auditing Standards No. 71, Interim Financial Information, on any unaudited financial statements included in the
Registration Statement; 
  
 (iii) on the basis of
the review referred to in clause (ii) above, a reading of the latest available interim financial statements of the Company, inquiries of officials of the Company who have responsibility for financial and accounting matters and other specified
procedures, nothing came to their attention that caused them to believe that: 
  
 (A) the unaudited financial statements, if any, and any summary of earnings included in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Act and the
related published Rules and Regulations or any material modifications should be made to such unaudited financial statements and summary of earnings for them to be in conformity with generally accepted accounting principles; 
  
 (B) if any unaudited “capsule” information is contained in the
Prospectus, the unaudited consolidated net revenues, income before provision for income taxes and extraordinary items, net income or other amounts constituting such “capsule” information and described in such letter do not agree with the
corresponding amounts set forth in the unaudited consolidated financial statements or were not determined on a basis substantially consistent with that of the corresponding amounts in the audited statements of income; 
  

 8 

 (C) at the date of the latest available balance sheet read by such accountants, or at a subsequent
specified date not more than three business days prior to the date of the such letter, there was any change in the capital stock or any increase in short-term indebtedness or long-term debt of the Company and its consolidated subsidiaries or, at the
date of the latest available balance sheet read by such accountants, there was any decrease in consolidated net assets, as compared with amounts shown on the latest balance sheet included in the Prospectus; or 
  
 (D) for the period from the closing date of the latest income statement
included in the Prospectus to the closing date of the latest available income statement read by such accountants there were any decreases, as compared with the corresponding period of the previous year and with the period of corresponding length
ended the date of the latest income statement included in the Prospectus, in consolidated net revenues, in the total or per share amounts of income before provision for income taxes and extraordinary items or net income or in the ratio of earnings
to fixed charges; 
  
 except in all cases set forth in clauses
(C) and (D) above for changes, increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter; and 
  
 (iv) they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other
financial information contained in the Prospectus (in each case to the extent that such dollar amounts, percentages and other financial information are derived from the general accounting records of the Company and its subsidiaries subject to the
internal controls of the Company’s accounting system or are derived directly from such records by analysis or computation) with the results obtained from inquiries, a reading of such general accounting records and other procedures specified in
such letter and have found such dollar amounts, percentages and other financial information to be in agreement with such results, except as otherwise specified in such letter. 
  
 All financial statements and schedules included in material incorporated by reference into the Prospectus shall be deemed
included in the Prospectus for purposes of this subsection. 
  
 (b) The Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 4(a) of this Agreement. No stop order suspending the effectiveness of the Registration
Statement or of any part thereof shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company or any Underwriter, shall be contemplated by the Commission. 
  
 (c) Subsequent to the execution of the Terms Agreement,
there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as one
enterprise which, in the judgment of a 

  

 9 

 
majority in interest of the Underwriters including any Representatives, is material and adverse and makes it impractical or inadvisable to proceed with
completion of the public offering or the sale of and payment for the Offered Securities; (ii) any downgrading in the rating of any debt securities of the Company by any “nationally recognized statistical rating organization” (as
defined for purposes of Rule 436(g) under the Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications
of a possible upgrading, and no implication of a possible downgrading, of such rating); (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the
judgment of a majority in interest of the Underwriters including any Representatives, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of
dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange, or any suspension of trading
of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of securities or clearance
services in the United States; or (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in
the judgment of a majority in interest of the Underwriters including any Representatives, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of
the public offering or the sale of and payment for the Offered Securities. 
  
 (d) The Representatives shall have received an opinion, dated the Closing Date, of the General Counsel of the Company to the effect that: 
  
 (i) The Company is an existing corporation in good standing under the laws of the State of Delaware,
with corporate power and authority to own its properties and conduct its business as described in the Prospectus; and the Company is duly qualified to do business as a foreign corporation in good standing in all other jurisdictions in which its
ownership or lease of property or the conduct of its business requires such qualification; 
  
 (ii) The Indenture has been duly authorized, executed and delivered by the Company and has been duly qualified under the Trust Indenture
Act; the Offered Securities have been duly authorized; the Offered Securities other than any Contract Securities have been duly executed, authenticated, issued and delivered; the Indenture and the Offered Securities other than any Contract
Securities constitute, and any Contract Securities, when executed, authenticated, issued and delivered in the manner provided in the Indenture and sold pursuant to Delayed Delivery Contracts, will constitute, valid and legally binding obligations of
the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to 

  

 10 

 
general equity principles; and the Offered Securities other than any Contract Securities conform, and any Contract Securities, when so issued and delivered
and sold will conform, to the description thereof contained in the Prospectus; 
  
 (iii) No consent, approval, authorization or order of, or filing with, any governmental agency or body or any court is required for the
consummation of the transactions contemplated by the Terms Agreement (including the provisions of this Agreement) in connection with the issuance or sale of the Offered Securities by the Company, except such as have been obtained and made under the
Act and the Trust Indenture Act and such as may be required under state securities laws; 
  
 (iv) The execution, delivery and performance of the Indenture, the Terms Agreement (including the provisions of this Agreement) and any
Delayed Delivery Contracts and the issuance and sale of the Offered Securities and compliance with the terms and provisions thereof will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, any
statute, any rule, regulation or order of any governmental agency or body or any court having jurisdiction over the Company or any subsidiary of the Company or any of their properties, or any material agreement or instrument to which the Company or
any such subsidiary is a party or by which the Company or any such subsidiary is bound or to which any of the properties of the Company or any such subsidiary is subject, or the charter or by-laws of the Company or any such subsidiary, and the
Company has full power and authority to authorize, issue and sell the Offered Securities as contemplated by the Terms Agreement (including the provisions of this Agreement); 
  
 (v) The Registration Statement has become effective under the Act, the Prospectus was filed with the
Commission pursuant to the subparagraph of Rule 424(b) specified in such opinion on the date specified therein, and, to the best of the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or any part
thereof has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Act, and the registration statement relating to the Registered Securities, as of its effective date, the Registration Statement
and the Prospectus, as of the date of the Terms Agreement, and any amendment or supplement thereto, as of its date, complied as to form in all material respects with the requirements of the Act, the Trust Indenture Act and the Rules and Regulations;
such counsel have no reason to believe that such registration statement, as of its effective date, the Registration Statement, as of the date of the Terms Agreement or as of the Closing Date, or any amendment thereto, as of its date or as of the

Agreement or as of such Closing Date, or any amendment or supplement thereto, as of its date or as of the Closing Date, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements
therein, in the 

  

 11 

 
light of the circumstances under which they were made, not misleading; the descriptions in the Registration Statement and Prospectus of statutes, legal and

such counsel such documents as they request for the purpose of enabling them to pass upon such matters. 
  
 (f) The Representatives shall have received a certificate, dated the Closing Date, signed by any two of the chairman of the board of
directors, the chief executive officer, the president, the chief financial officer, the chief administrative officer, the chief accounting officer and any Managing Director of the Company in which such officers, to the best of their knowledge after
reasonable investigation, shall state that the representations and warranties of the Company in this Agreement are true and correct, that the Company has complied with all agreements and satisfied all conditions on its part to be performed or
satisfied hereunder at or prior to the Closing Date, that no stop order suspending the effectiveness of the Registration Statement or of any part thereof has been issued and no proceedings for that purpose have been instituted or are contemplated by

 (g) The Representatives shall have received a letter, dated

 6. Indemnification and
Contribution. 
  
 (a) The Company will
indemnify and hold harmless each Underwriter, its partners, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter
in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any
Underwriter through the Representatives, if any, specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in the Terms Agreement.

  
 (b) Each Underwriter will severally and not
jointly indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities to which the Company
may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or the alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was
made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives, if any, specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by
the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the
information described as such in the Terms Agreement. 
  

 13 

 (c) Promptly after receipt by an indemnified party under this Section of notice of the
commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified
party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the
defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter
of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or behalf of an indemnified party. 
  
 (d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an
indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection
(a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the
one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and
commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified
party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include 

  

 14 

 
any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the
subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection
(d) to contribute are several in proportion to their respective underwriting obligations and not joint. 
  
 (e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company
within the meaning of the Act. 
  
 7. Default of
Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities under the Terms Agreement and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters
agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the Lead Underwriter may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any
of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments under the Terms Agreement (including the provisions of this
Agreement), to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of Offered Securities with respect to which such default
or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the Lead Underwriter and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after
such default, the Terms Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 8. As used in this Agreement, the term “Underwriter” includes any person
substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default. The respective commitments of the several Underwriters for the purposes of this Section shall be determined
without regard to reduction in the respective Underwriters’ obligations to purchase the principal amounts of the Offered Securities set forth opposite their names in the Terms Agreement as a result of Delayed Delivery Contracts entered into by
the Company. 
  
 8. Survival of Certain Representations and
Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and 

  

 15 

 
of the several Underwriters set forth in or made pursuant to the Terms Agreement (including the provisions of this Agreement) will remain in full force and
effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive
delivery of and payment for the Offered Securities. If the Terms Agreement is terminated pursuant to Section 7 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company shall remain
responsible for the expenses to be paid or reimbursed by it pursuant to Section 4 and the respective obligations of the Company and the Underwriters pursuant to Section 6 shall remain in effect. If the purchase of the Offered Securities by
the Underwriters is not consummated for any reason other than solely because of the termination of the Terms Agreement pursuant to Section 7 or the occurrence of any event specified in clause (iii), (iv), (v), (vi) or (vii) of
Section 5(c), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities. 
  
 9. Notices. All communications hereunder will be in writing and, if
sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to them at their address furnished to the Company in writing for the purpose of communications hereunder or, if sent to the Company, will be mailed, delivered or
telegraphed and confirmed to it at Eleven Madison Avenue, New York, New York 10010-3629, Attention: Corporate Treasury Department (Facsimile No.: (212) 325-8227). 
  
 10. Successors. The Terms Agreement (including the provisions of this Agreement) will inure to the benefit of and be
binding upon the Company and such Underwriters as are identified in the Terms Agreement and their respective successors and the officers and directors and controlling persons referred to in Section 6, and no other person will have any right or
obligation hereunder. 
  
 11. Representation of
Underwriters. Any Representatives will act for the several Underwriters in connection with the financing described in the Terms Agreement, and any action under such Terms Agreement (including the provisions of this Agreement) taken by the
Representatives jointly or by the Lead Underwriter will be binding upon all the Underwriters. 
  
 12. Counterparts. The Terms Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same
Agreement. 
  
 13. Applicable Law. This Agreement
and the Terms Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of laws. 
  
 The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in
The City of New York in any suit or proceeding arising out of or relating to the Terms Agreement (including the provisions of this Agreement) or the transactions contemplated thereby.

 There has been no alteration in the status or condition of the Company as disclosed by the searches and enquiries referred to in Schedule 1 (Documents

all relevant jurisdictions other than Singapore. 

  

	 	(t)	There are no provisions of the laws of any relevant jurisdiction (other than Singapore) which would be contravened by the formation of the Selling Stockholder, the contribution of

the contribution of the Contract Shares as capital in the Selling Stockholder and/or the Selling Stockholder Actions falls to be performed in or is otherwise subject to the laws of any relevant jurisdiction other than Singapore, its performance will
not be illegal by virtue of the laws of that jurisdiction. 

  

	 	(u)	All consents, approvals, authorisations, licences, exemptions or orders required from any relevant governmental or other regulatory authorities outside Singapore and all other
requirements outside Singapore for the formation of the Selling Stockholder, the contribution of the Contract Shares as capital in the Selling Stockholder and the Selling Stockholder Actions have been duly obtained or fulfilled and are and will

 SCHEDULE 3 
 RESERVATIONS 
  
 The opinions in this Opinion Letter are subject to the following reservations. 
  

	10.	EFFECTIVENESS OF TRANSFER OF PROPRIETARY RIGHTS 

  
 We express no opinion as to whether the Company has good legal or other title to the Contract Shares, or as to the existence or value of the same. 
  

	11.	OTHER RESERVATIONS 

  

	 	(w)	The courts of Singapore are bound to follow judicial precedents laid down by superior courts of Singapore. However, the Court of Appeal, which is the highest court in Singapore, has
power to depart from such precedents where adherence will cause injustice in a particular case or constrain the development of law in conformity with the circumstances of Singapore. 

  

	 	(x)	A court in Singapore will not be automatically bound to stay proceedings brought in its jurisdiction despite the existence of an exclusive jurisdiction provision in an agreement
naming the foreign jurisdiction where the proceedings should be brought. The Singapore courts have the discretion as to whether or not to grant an application for a stay notwithstanding such an exclusive jurisdiction clause.
