   This summary may not contain all of the information that may be important to

                                  The Company

Overview

   Equinix designs, builds and operates neutral Internet Business Exchange
centers, or IBX centers, where Internet businesses place their equipment and
their network facilities in order to interconnect with each other to improve
Internet performance. Our neutral IBX centers provide content providers,
application service providers and e-commerce companies with the ability to
directly interconnect with a choice of bandwidth providers, Internet service
providers, and site and performance management companies. Equinix IBX centers
enable Internet companies to quickly, easily and privately interconnect with a
choice of business partners and customers, providing them with the flexibility,
speed and adaptability they need to accelerate business growth.

   Equinix currently has IBX centers in the Washington, D.C. metropolitan area,
the New York metropolitan area and in Silicon Valley. We intend to complete
construction of five additional IBX centers and several expansion projects by
May 2001, resulting in a total of eight IBX centers in the U.S. and Europe.

   We were founded in June 1998. In April 1999, our first customer contract was
signed and we began recognizing revenue in November 1999. We have not yet been
profitable and expect to incur significant additional losses.

The Equinix Solution

   Our IBX centers will provide environments that stimulate efficient business
growth. We are able to provide the following key benefits to our customers:

  . choice of product and service providers;

  . opportunity to increase revenues and reduce costs;

  . scalability; and

  . reliability.

Recent Developments

   On May 16, 2000, Peter F. Van Camp joined Equinix as our chief executive
officer. Prior to joining Equinix, Mr. Van Camp was the president of the
Americas region for UUNet, a division of WorldCom. Albert M. Avery, IV, one of
our founders, will continue as our president and will assume responsibilities
as our chief operating officer. Mr. Van Camp will also join our board of
directors.

   On May 23, 2000 we entered into a purchase agreement regarding our purchase
of real property in San Jose, California for approximately $82.0 million. The
sale is scheduled to close on June 15, 2000, pending additional due diligence
by us. We currently anticipate that a third party financier will purchase the
property at the closing and then will lease this property back to us pursuant
to a long-term lease. There can be no assurance that we will be able to secure
this arrangement. If we are not able to secure this arrangement we have the
option to purchase the property directly. However, we do not intend to do so at
this time.

   Equinix is located at 901 Marshall Street, Redwood City, California 94063.
Our phone number is (650) 298-0400.

                         Summary of the Exchange Offer

Securities Offered..........  Up to $200 million principal amount of 13%
                              Senior Notes due 2007, which will be
                              registered under the Securities Act. The
                              terms of the exchange notes and the initial
                              notes are identical except for transfer
                              restrictions and registration rights
                              relating to the initial notes that will not
                              be applicable to the exchange notes.

Issuance of Initial Notes...  The initial notes were issued on December
                              1, 1999 to Salomon Smith Barney Inc.,
                              Morgan Stanley & Co. Incorporated and
                              Goldman, Sachs & Co., who placed the
                              initial notes with qualified institutional
                              buyers and institutional accredited
                              investors, and to buyers in offshore
                              transactions in reliance on Regulation S
                              under the Securities Act.

The Exchange Offer..........  We are offering to exchange $1,000
                              principal amount of exchange notes for each
                              $1,000 principal amount of initial notes.
                              There are $200 million aggregate principal
                              amount of initial notes outstanding. The
                              issuance of the exchange notes is intended
                              to satisfy our obligations contained in the
                              registration rights agreement we entered
                              into with Salomon Smith Barney Inc., Morgan
                              Stanley & Co. Incorporated and Goldman,
                              Sachs & Co. in connection with the issuance
                              of the initial notes.

Conditions to the Exchange
Offer.......................  The exchange offer is not conditioned upon
                              any minimum principal amount of initial
                              notes being tendered for exchange. However,
                              the exchange offer is subject to customary
                              conditions, which may be waived by us. See
                              "The Exchange Offer--Conditions." Except
                              for the requirements of applicable federal
                              and state securities laws, there are no
                              federal or state regulatory requirements to
                              be complied with or obtained by us in
                              connection with the exchange offer.

Procedures for Tendering....  If you want to tender your initial notes in
                              the exchange offer, you must complete, sign
                              and date the letter of transmittal
                              according to the instructions contained in
                              this prospectus and the letter of
                              transmittal. You must then mail or fax the
                              letter of transmittal, together with any
                              other required documents, to the exchange
                              agent, either with the initial notes to be
                              tendered or in compliance with the
                              specified procedures for guaranteed
                              delivery of initial notes. You should allow
                              sufficient time to ensure timely delivery.
                              Some brokers, dealers, commercial banks,
                              trust companies and other nominees may also
                              effect tenders by book-entry transfer. If
                              you own initial notes registered in the
                              name of a broker, dealer, commercial bank,
                              trust company or other nominee, you are
                              urged to contact that person promptly if
                              you wish to tender initial notes in the
                              exchange offer. Letters of transmittal and
                              certificates representing the initial notes
                              should not be sent to Equinix.

                              The tender of initial notes may be
                              withdrawn at any time before the expiration
                              date. Any initial note not accepted for
                              exchange for any reason will be returned
                              without expense to the tendering holder as
                              promptly as practicable after the

Notes.......................  Upon effectiveness of the registration
                              statement of which this prospectus
                              constitutes a part and consummation of the
                              exchange offer, we will accept any and all
                              initial notes that are properly tendered in
                              the exchange offer on or before 5:00 p.m.,
                              New York City time, on the expiration date.

                              acceptance of the initial notes. See "The

                              for Exchange; Delivery of Exchange Notes."

Tax Considerations..........  For U.S. federal income tax purposes, the

                              notes should not be considered a sale or
                              exchange or otherwise a taxable event to
                              the holders of notes. See "United States
                              Federal Income Tax Considerations."

Use of Proceeds.............  We will receive no proceeds from the
                              exchange offer.

Exchange Agent..............  State Street Bank and Trust Company of
                              California, N.A. is serving as exchange
                              agent in connection with the exchange
                              offer.

Fees and Expenses...........  We will bear all expenses related to the
                              exchange offer. See "The Exchange Offer--

Consequences of Not
Exchanging the Initial
Notes.......................  If you do not tender your initial notes or
                              your initial notes are not properly
                              tendered, the existing transfer
                              restrictions will continue to apply. The
                              initial notes are currently eligible for
                              sale under Rule 144A through the PORTAL
                              Market. Because we anticipate that most
                              holders will elect to exchange initial
                              notes for exchange notes due to the absence
                              of restrictions on the resale of exchange
                              notes under the Securities Act in most
                              cases, we anticipate that the liquidity of
                              the market for any initial notes remaining
                              after the consummation of the exchange
                              offer may be substantially limited. See
                              "Risk Factors--There could be negative
                              consequences to you if you do not exchange
                              your initial notes for exchange notes."

                   Summary Description of the Exchange Notes

   The terms of the exchange notes and the initial notes are identical in all
respects, except that the terms of the exchange notes do not include the
transfer restrictions and registration rights relating to the initial notes.
The initial notes and the exchange notes are referred to collectively as the
notes.

   The exchange notes will bear interest from the most recent date to which
interest has been paid on the initial notes. Initial notes accepted for
exchange will cease to accrue interest from and after the date of completion of
the exchange offer.

Maturity Date...............  December 1, 2007.

Interest....................  The interest on the notes will be payable semi-
                              annually in arrears on each June 1 and December
                              1, commencing on June 1, 2000.

Interest Escrow.............  We have deposited with the escrow agent an amount
                              of cash or U.S. government securities totaling
                              approximately $37.0 million that, together with
                              the proceeds from their investment, will be
                              sufficient to pay, when due, the first three
                              interest payments on the notes, with us retaining
                              any balance. The notes will be collateralized by
                              a first priority security interest in the escrow
                              account.

Sinking Fund................  None.

Optional Redemption.........  Generally, we may not redeem the notes before
                              December 1, 2003. On or after December 1, 2003,
                              we may redeem the notes, in whole or in part, at
                              any time, at the redemption prices set forth
                              under the section entitled "Description of the
                              Exchange Notes" together with accrued and unpaid
                              interest, if any, to the redemption date.

Change of Control...........  Upon a "Change of Control" as defined under the
                              section entitled "Description of the Notes," you
                              as a holder of notes will have the right to
                              require us to repurchase all of your notes at a
                              repurchase

                                       4

                              price equal to 101% of the aggregate principal
                              amount of such notes, plus accrued and unpaid
                              interest, if any, through the date of repurchase.

Ranking.....................  Except for the noteholders' security interest in
                              the escrow account, the notes will be general
                              unsecured obligations and will rank without
                              preference with all of our other existing and
                              future senior unsecured indebtedness. The notes
                              will be effectively subordinated to all our
                              existing and future secured indebtedness to the
                              extent of the value of the assets that secure
                              such indebtedness. The notes will also be
                              subordinated to all of our subsidiaries' existing
                              or future indebtedness, whether or not secured.
                              At present, the notes are subordinated to $12.4
                              million of existing indebtedness.

Restrictive Covenants.......  The indenture under which the notes will be
                              issued will limit:

                              . the incurrence of additional indebtedness or
                                preferred stock by us and our subsidiaries;

                              . the payment of dividends on, and repurchase or
                                redemption of, our capital stock and our
                                subsidiaries' capital stock and the repurchase
                                or redemption of our subordinated obligations;

                              . our making of investments;

                              . the selling of our assets or the stock of our
                                subsidiaries;

                              . transactions with our affiliates;

                              . the incurrence of additional liens;

                              . our ability to permit restrictions to exist on
                                the ability of our subsidiaries to pay
                                dividends or make payments to us; and

                              . our ability to engage in consolidations,
                                mergers and transfers of all or substantially
                                all of our assets.

                              All of these limitations and prohibitions will be
                              subject to a number of important qualifications
                              and exceptions. See "Description of the Exchange
                              Notes."

Exchange Rights.............  Holders of the exchange notes will not be
                              entitled to any exchange or registration rights
                              relating to the exchange notes. Holders of the
                              initial notes are entitled to certain exchange
                              rights under the registration rights agreement
                              entered into concurrently with the initial
                              offering between us and Salomon Smith Barney
                              Inc., Morgan Stanley & Co. Incorporated and
                              Goldman, Sachs & Co. This exchange offer is
                              intended to satisfy our obligations under the
                              registration rights agreement. Once the exchange
                              offer is consummated, we will have no further
                              obligations to register any of the initial notes
                              not tendered by the holders for exchange. See
                              "Risk Factors--There could be negative
                              consequences to you if you do not exchange your
                              initial notes for exchange notes."

(1) Adjusted EBITDA consists of the net loss excluding interest, income taxes,
    depreciation and amortization of capital assets and amortization of
    deferred stock-based compensation. Adjusted EBITDA is presented to enhance
    an understanding of our operating results and is not intended to represent
    cash flow or results of operations in accordance with generally accepted
    accounting principles for the period indicated and may be calculated
    differently than adjusted EBITDA for other companies. Adjusted EBITDA is
    not a measure determined under generally accepted accounting principles nor
    is it a measure of liquidity.
(2) In calculating the ratio of earnings to fixed charges, earnings consist of
    net loss before income tax expense and fixed charges. Fixed charges consist
    of interest expense, capitalized interest, amortized discounts and
    capitalized expenses related to indebtedness and an estimate of the
    interest within rental expense. The ratio of earnings to fixed charges was
    less than 1.0 to 1.0 for each of the periods presented. Earnings available
    for fixed charges were thus inadequate to cover fixed charges. The coverage
    deficiency for the period from June 22, 1998 (inception) to December 31,
    1998, the year ended December 31, 1999 and the three months ended March 31,
    1999 and 2000 was $1,019,700, $20,790,600, $1,344,900 and $18,008,800,
    respectively.

                                  RISK FACTORS

   You should carefully consider the information set forth under the caption
"Risk Factors" and all other information in this prospectus before tendering
your initial notes in the exchange offer, including information in the section
of this prospectus entitled "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Special Note Regarding Forward-Looking
Statements."

Risks Related to Our Business

Our business model is new and unproven and we may not succeed in generating
sufficient revenue to sustain or grow our business.

   We were founded in June 1998. Except for fiber connectivity from our
telecommunication carriers, the construction of our first IBX center was
completed in July 1999. We began accepting customers the same month but did not
recognize any revenue until November 1999 as the sales cycle was not complete.
Our limited history and lack of meaningful financial or operating data makes
evaluating our business operations. Moreover, the neutrality aspect of our
business model is unique and largely unproven. We expect that we will encounter
challenges and difficulties frequently experienced by early-stage companies in
new and rapidly evolving markets, such as our ability to generate cash flow,
hire and train sufficient operational and technical talent, and implement our
plan with minimal delays. We may not successfully address any or all of these
challenges and the failure to do so would seriously harm our business plan and
operating results, and affect our ability to raise additional funds.

We have a history of losses, and we expect our operating expenses and losses to
increase significantly.

   As an early-stage company without recognized revenues, we have experienced
operating losses since inception. As of March 31, 2000, we had cumulative net
losses of $39.8 million and cumulative cash used by operating activities of
$14.9 million since inception. We expect to incur significant losses in the
future. In addition, as we commence operations, our losses will increase as we:

  . increase the number of IBX centers;

  . increase our sales and marketing activities, including expanding our
     direct sales force; and

  . enlarge our customer support and professional services organizations.

   As a result, we must significantly increase our revenues to become
profitable.

Because our ability to generate enough revenues to achieve profitability
depends on numerous factors, we may not become profitable.

   Our IBX centers may not generate sufficient revenue to achieve
profitability. Our ability to generate sufficient revenues to achieve
profitability will depend on a number of factors, including:

  . the timely completion of our IBX centers;

  . demand for space and services, including private interconnection
     services, at our IBX centers;

  . our pricing policies and the pricing policies of our competitors;

  . the timing of customer installations and related payments;

  . competition in our markets;

  . the timing and magnitude of our expenditures for sales and marketing;

  . direct costs relating to the expansion of our operations;

  . growth of Internet use;

  . economic conditions specific to the Internet industry; and

  . general economic factors.

                                       8
<PAGE>

We are substantially leveraged and we may not generate sufficient cash flow to
meet our debt service and working capital requirements.

   We are highly leveraged since the issuance of the initial notes. We have
total indebtedness of $213.7 million. Our highly leveraged position could have
important consequences, including:

  .  impairing our ability to obtain additional financing for working
     capital, capital expenditures, acquisitions or general corporate
     purposes;

  .  requiring us to dedicate a substantial portion of our operating cash
     flow to paying principal and interest on our indebtedness, thereby
     reducing the funds available for operations;

  .  limiting our ability to grow and make capital expenditures due to the
     financial covenants contained in our debt arrangements;

  .  impairing our ability to adjust rapidly to changing market conditions,
     invest in new or developing technologies, or take advantage of
     significant business opportunities that may arise; and

  .  making us more vulnerable if a general economic downturn occurs or if
     our business experiences difficulties.

   In the past, we have experienced unforeseen delays in connection with our
IBX construction activities. We will need to successfully implement our
business strategy on a timely basis to meet our debt service and working
capital needs. We may not successfully implement our business strategy, and
even if we do, we may not realize the anticipated results of our strategy or
generate sufficient operating cash flow to meet our debt service obligations
and working capital needs.

   In the event our cash flow is inadequate to meet our obligations, we could
face substantial liquidity problems. If we are unable to generate sufficient
cash flow or otherwise obtain funds needed to make required payments under our
indebtedness, or if we breach any covenants under our indebtedness, we would be
in default under its terms and the holders of such indebtedness may be able to
accelerate the maturity of such indebtedness, which could cause defaults under
our other indebtedness.

If we do not obtain significant additional funds, we may not be able to
complete our rollout plan on a timely basis, or at all.

   Equinix currently has three IBX centers in operation. We intend to pursue 12
additional projects through May 2001--five of these projects will be new IBX
centers and seven of these will be expansion projects. We intend to finance the
construction of these IBX centers through our internal cash flow and
approximately $750.0 million of additional financing. If we cannot raise
sufficient additional funds on acceptable terms we may delay the rollout of
additional IBX centers or permanently reduce our rollout plans. We currently
have $241.7 million in cash, cash equivalents and short-term investments
available to us. We anticipate that these funds will be sufficient to fund the
capital expenditure and working capital requirements, including operating
losses associated with the initial rollout of seven IBX centers and expansion
projects within two of those IBX centers. To complete the implementation of our
rollout plan within our proposed time frame we anticipate that we will need to
raise funds through additional debt or equity financing. In the past, we have
had difficulties obtaining debt financing due to the early stage of our
company. Financing may not be available to us at the time we seek to raise
additional funds, or if such financing is available, it may only be available
on terms, or in amounts, which are unfavorable to us.

   The anticipated timing and amount of our capital requirements is forward-
looking and therefore inherently uncertain. In the past, we have experienced
unforeseen delays and expenses in connection with our IBX construction
activities. Our future capital requirements may vary significantly from what we
currently project and the timing of our rollout plan may be affected by
unforeseen construction delays and expenses and the

                                       9
<PAGE>

amount of time it takes us to lease space within our IBX centers. If we
encounter any of these problems or if we have underestimated our capital
expenditure requirements or the operating losses or working capital
requirements, we may require significantly more financing than we currently
anticipate.

Our rollout plan is preliminary and we may need to alter our plan and
reallocate funds.

   Our IBX center rollout plan is preliminary and has been developed from our
current market data and research, projections and assumptions. We expect to
continually reevaluate our business and rollout plan, including the size of our
IBX centers, in light of evolving competitive and market conditions, and as a
result, we may alter our IBX center rollout and reallocate funds, or eliminate
segments of our plan entirely if there are:

  . changes or inaccuracies in our market data and research, projections or
    assumptions;

  . unexpected results of operations or strategies in our target markets;

  . regulatory, technological, and competitive developments, including
    additional market developments and new opportunities; or

  . changes in, or discoveries of, specific market conditions or factors
    favoring expedited development in other markets.

If not properly managed, our growth and expansion could significantly harm our
business and operating results.

   Our anticipated growth may significantly strain our resources as a result of
an increase in the number of our employees, the number of operating IBX centers
and our international expansion. Any failure to manage growth effectively could
seriously harm our business and operating results. To succeed, we will need to:

  . hire and train new employees and qualified engineering personnel at each
    IBX center;

  . implement additional management information systems;

  . locate additional office space for our corporate headquarters;


  . improve our operating, administrative, financial and accounting systems
    and controls; and

  . maintain close coordination among our executive, engineering, accounting,
    finance, marketing, sales and operations organizations.

We face risks associated with international operations that could harm our
business.

   We intend to construct IBX centers outside of the United States and we will
commit significant resources to our international sales and marketing
activities. Our management has limited experience conducting business outside
of the United States and we may not be aware of all the factors that affect our
business in foreign jurisdictions. We will be subject to a number of risks
associated with international business activities that may increase our costs,
lengthen our sales cycles and require significant management attention. These
risks include:

  . increased costs and expenses related to the leasing of foreign centers;

  . difficulty or increased costs of constructing IBX centers in foreign
    countries;

  . difficulty in staffing and managing foreign operations;

  . increased expenses associated with marketing services in foreign
    countries;

  . business practices that favor local competition and protectionist laws;

  . difficulties associated with enforcing agreements through foreign legal
    systems;


                                       10
<PAGE>

  . general economic and political conditions in international markets;

  . potentially adverse tax consequences, including complications and
    restrictions on the repatriation of earnings;

  . currency exchange rate fluctuations;

  . unusual or burdensome regulatory requirements or unexpected changes to
    those requirements;

  . tariffs, export controls and other trade barriers; and

  . longer accounts receivable payment cycles and difficulties in collecting
    accounts receivable.

   To the extent that our operations are incompatible with, or not economically
viable within, any given foreign market, we may not be able to locate an IBX
center in that particular foreign jurisdiction.

We depend on third parties to provide Internet connectivity to our IBX centers;
if connectivity is not established or is delayed, our operating results and
cash flow will be adversely affected.

   The presence of diverse Internet fiber from communications carriers' fiber
networks to an Equinix IBX center is critical to our ability to attract new
customers. We believe that the availability of such carrier capacity will
directly affect our ability to achieve our projected results.

   We are not a communications carrier, and as such we rely on third parties to
provide our customers with carrier facilities. We intend to rely primarily on
revenue opportunities from our customers to encourage carriers to incur the
expenses required to build facilities from their points of presence to our IBX
centers. Carriers will likely evaluate the revenue opportunity of an IBX center
based on the assumption that the environment will be highly competitive. There
can be no assurance that, after conducting such an evaluation, any carrier will
elect to offer its services within our IBX centers.

   The construction required to connect multiple carrier facilities to our IBX
centers is complex and involves factors outside of our control, including
regulatory processes and the availability of construction resources. For
example, in the past carriers have experienced delays in connecting to our
facilities. If the establishment of highly diverse Internet connectivity to our
IBX centers does not occur or is materially delayed, our operating results and
cash flow will be adversely affected.

Our new management team must prove that it can work together effectively.

   We have recently hired many key personnel, including our chief executive
officer, chief financial and corporate development officer, vice president of
operations, vice president of worldwide sales, chief marketing officer, vice
president of IBX development and general counsel. As a result, our management
team has worked together for only a brief time. Our ability to effectively
execute our strategies will depend in part upon our ability to integrate our
current and future managers into our operations. If our executives are unable
to operate together effectively, our business, results of operations and
financial condition will be materially adversely affected.

We must retain and attract key personnel to maintain and grow our business.

   We require the services of additional personnel in positions related to our
growth. For example, we need to expand our marketing and direct sales
operations to increase market awareness of our IBX centers, market our services
to a greater number of enterprises and generate increased revenues. We also
require highly capable technical personnel to provide the quality services we
are promoting. As a result, we plan to hire additional personnel in related
capacities. Our success depends on our ability to identify, hire, integrate and
retain additional qualified personnel, including managers, particularly in
areas related to our anticipated growth and geographic expansion.


                                       11
<PAGE>

   We may not be successful in attracting, assimilating or retaining qualified
personnel. In addition, due to generally tight labor markets, our industry, in
particular, suffers from a lack of available qualified personnel. If we lose
one or more of our key employees, we may not be able to find a replacement and
our business and operating results could be adversely affected.

We will operate in a new highly competitive market and we may be unable to
compete successfully against new entrants and established companies with
greater resources.

   In a market that we believe will likely have an increasing number of
competitors, we must be able to differentiate ourself from existing providers
of space for telecommunications equipment and web hosting companies. We may
also face competition from persons seeking to replicate our IBX concept. Our
competitors may operate more successfully than us or form alliances to acquire
significant market share. Furthermore, enterprises that have already invested
substantial resources in peering arrangements may be reluctant or slow to adopt
our approach that may replace, limit or compete with their existing systems. If
we are unable to complete our IBX centers in a timely manner, other companies
may be able to attract the same customers that we are targeting. Once the
customers are located in our competitors' facilities, it will be extremely
difficult to convince them to relocate to our IBX centers.

   Some of our potential competitors have longer operating histories and
significantly greater financial, technical, marketing and other resources than
we do. Because of their greater financial resources, some of these companies
have the ability to adopt aggressive pricing policies. As a result, in the
future, we may suffer from pricing pressure which would adversely affect our
ability to generate revenues and affect our operating results. See "Business--
Competition."

Any failure of our physical infrastructure or services could lead to
significant costs and disruptions which could reduce our revenue and harm our
business reputation and financial results.

   Our business depends on providing our customers with highly reliable
service. The services we provide are subject to failure resulting from numerous
factors, including:

  . human error;

  . physical or electronic security breaches;

  . fire, earthquake, flood and other natural disasters;

  . power loss; and

  . sabotage and vandalism.

   Problems at one or more of our centers, whether or not within our control,
could result in service interruptions or significant equipment damage. Any loss
of services, particularly in the early stage of our development, could reduce
the confidence of our customers and could consequently impair our ability to
obtain and retain customers which would adversely affect our ability to
generate revenues and affect our operating results.

We may still discover that our computer systems and those of third parties with
whom we do business may not be year 2000 compliant, which may cause system
failure and disruptions of operations.

   As of May 31, 2000, we had not experienced any year 2000-related disruption
in the operation of our systems. However, we cannot assure you that we will not
discover any year 2000 compliance problems. Our failure to fix or replace our
software, hardware or services on a timely basis could result in lost revenues,
increased operating costs and the loss of customers and other business
interruptions, any of which could have a material adverse effect on our
business. Moreover, the failure to adequately address year 2000 compliance
issues in our information technology systems could result in claims of
mismanagement, misrepresentation or breach of contract and related litigation,
which could be costly and time-consuming to defend.


                                       12
<PAGE>

   In addition, we have not experienced any year 2000-related disruption in the
systems of third parties with whom we do business and we have assurances from
our material hardware and software vendors that their products are year 2000
compliant. Although we have not incurred any material expenditure in connection
with identifying or evaluating year 2000 compliance issues to date, we do not
at this time possess the information necessary to estimate the potential costs
of revisions or replacements to our software and systems or third-party
software, hardware or services that are determined not to be year 2000
compliant. Such expenses could have a material adverse effect on our business.

Because we depend on the development and growth of a balanced customer base,
failure to attract this base could harm our business and operating results.

   Our ability to maximize revenues depends on our ability to develop and grow
a balanced customer base as we roll out our IBX centers. Our ability to attract
customers to our IBX centers will depend on a variety of factors, including the
presence of multiple carriers, the overall mix of our customers, our operating
reliability and security and our ability to effectively market our services.
Construction delays, our inability to find suitable locations to build
additional IBX centers, equipment and material shortages or our inability to
obtain necessary permits on a timely basis could delay our IBX center rollout
schedule and prevent us from developing our anticipated customer base.

   A customer's decision to lease cabinet space in our IBX centers typically
involves a significant commitment of resources and will be influenced by, among
other things, the customer's confidence that other Internet and e-commerce
related businesses will be located in a particular IBX center. In particular,
some customers will be reluctant to commit to locating in our IBX centers until
they are confident that the IBX center has adequate carrier connections. Our
success will also depend upon generating significant interconnection revenues
from customers, which may depend upon a balanced customer base, as well as upon
the success of our IBX centers at facilitating business among customers.

   In addition, some of our customers will be Internet companies that face many
competitive pressures and that may not ultimately be successful. If these
customers do not succeed, they will not continue to use our IBX centers. This
may be disruptive to our business and may adversely affect our operating
results.

Risks Related to Our Industry

If use of the Internet and electronic business does not continue to grow, a
viable market for our IBX centers may not develop.

   Rapid growth in the use of and interest in the Internet has occurred only
recently. Acceptance and use may not continue to develop at historical rates
and a sufficiently broad base of consumers may not adopt or continue to use the
Internet and other online services as a medium of commerce. Demand and market
acceptance for recently introduced Internet services and products are subject
to a high level of uncertainty and there are few proven services and products.
As a result, we cannot be certain that a viable market for our IBX centers will
emerge or be sustainable.

We must respond to rapid technological change and evolving industry standards
in order to meet the needs of our customers.

   The market for IBX centers will be marked by rapid technological change,
frequent enhancements, changes in customer demands and evolving industry
standards. Our success will depend, in part, on our ability to address the
increasingly sophisticated and varied needs of our current and prospective
customers. Our failure to adopt and implement the latest technology in our
business could negatively affect our business and operating results.

   In addition, we have made and will continue to make assumptions about the
standards that may be adopted by our customers and competitors. If the
standards adopted differ from those on which we have based

                                       13
<PAGE>

anticipated market acceptance of our services or products, our existing
services could become obsolete. This would have a material adverse effect on
our businesses.

Government regulation may adversely affect the use of the Internet and our
business.

   Laws and regulations governing Internet services, related communications
services and information technologies, and electronic commerce are beginning to
emerge but remain largely unsettled, even in areas where there has been some
legislative action. It may take years to determine whether and how existing
laws, such as those governing intellectual property, privacy, libel,
telecommunications, and taxation, apply to the Internet and related services
such as ours. In addition, the development of the market for online commerce
and the displacement of traditional telephony services by the Internet and
related communications services may prompt increased calls for more stringent
consumer protection laws or other regulation, both in the United States and
abroad, that may impose additional burdens on companies conducting business
online and their service providers. The adoption or modification of laws or
regulations relating to the Internet, or interpretations of existing law, could
have a material adverse effect on our business.

Risks Related to the Exchange Offer

There could be negative consequences to you if you do not exchange your initial
notes for exchange notes.

   Following the consummation of the exchange offer, holders who did not tender
their initial notes generally will not have any further rights under the
registration rights agreement and these initial notes will continue to be
subject to restrictions on transfer. As a result of making the exchange offer,
we will have fulfilled our obligations under the registration rights agreement.
Holders who do not tender their initial notes generally will not have any
further registration rights or rights to receive the liquidated damages
specified in the registration rights agreement for our failure to register the
exchange notes. In addition, the initial notes that are not exchanged for
exchange notes will remain restricted securities. Accordingly, the initial
notes may be resold only:

  . to Equinix or one of its subsidiaries;

  . to a qualified institutional buyer;

  . to an institutional accredited investor;

  . to a party outside the United States under Regulation S under the
    Securities Act;

  . under an exemption from registration provided by Rule 144 under the
    Securities Act; or

  . under an effective registration statement.

The issuance of the exchange notes may adversely affect the market for the
initial notes.

   Following commencement of the exchange offer, you may continue to trade the
initial notes on the Private Offerings, Resales and Trading through Automated
Linkages, or PORTAL, market. However, if initial notes are tendered for
exchange and accepted in the exchange offer, the trading market for untendered
and tendered but unaccepted initial notes could be adversely affected. Any
initial notes tendered and exchanged in the exchange offer will reduce the
aggregate principal amount of initial notes outstanding. Because we anticipate
that most holders will elect to exchange their initial notes for exchange notes
due to the absence of most restrictions on the resale of exchange notes, we
anticipate that the liquidity of the market for any initial notes remaining
outstanding after the exchange offer may be substantially limited.

You may find it difficult to sell your exchange notes.

   The exchange notes will be registered under the Securities Act but will not
be eligible for trading on the PORTAL market. The exchange notes will
constitute a new issue of securities with no established trading market, and
there can be no assurance as to:

  . the development of any market for the exchange notes;

                                       14
<PAGE>

  . the liquidity of any market for the exchange notes that may develop;

  . your ability to sell your exchange notes; or

  . the price at which you would be able to sell your exchange notes.

   We have been advised by the initial purchasers for the initial notes that
they presently intend to make a market in the exchange notes. However, they are
not obligated to do so and may discontinue any market-making activity relating
to the exchange notes at any time without notice. If a market for the exchange
notes were to exist, the exchange notes could trade at prices that may be
higher or lower than their principal amount or purchase price, depending on
many factors, including prevailing interest rates, the market for similar
debentures and our financial performance. Historically, the market for non-
investment grade debt has been subject to disruptions that have caused
substantial volatility in the prices of securities similar to the exchange
notes. We cannot assure you that the market for the exchange notes, if any,
will not be subject to similar disruptions.

Some people who participate in the exchange offer must deliver a prospectus in
connection with resales of the exchange notes.

   Based on certain no-action letters issued by the staff of the Securities and
Exchange Commission, we believe that you may offer for resale, resell or
otherwise transfer the exchange notes without compliance with the registration
and prospectus delivery requirements of the Securities Act. However, in some
instances, you will remain obligated to comply with the registration and
prospectus delivery requirements of the Securities Act to transfer your
exchange notes. In these cases, if you transfer any exchange note without
delivering a prospectus meeting the requirements of the Securities Act or
without an exemption from registration of your exchange notes under this Act,
you may incur liability under the Securities Act. We do not and will not assume
or indemnify you against this liability. See "The Exchange Offer."

Risks Related to the Exchange Notes

The exchange notes are unsecured and effectively rank behind our secured
indebtedness.

   The exchange notes will be general unsecured senior obligations and will
rank equally in right of payment with all our existing and future senior
indebtedness. The exchange notes will be effectively subordinated to all of our
secured indebtedness to the extent of the value of the assets securing such
indebtedness. All of the obligations under our current credit facilities are
either secured by all of the assets of Equinix-DC, Inc. or the assets purchased
from the proceeds of specific indebtedness. We anticipate that all of the
obligations under our future credit facilities will be secured. In a
bankruptcy, liquidation or reorganization of our company, our assets securing
other indebtedness will be available to pay obligations on the exchange notes
only after all indebtedness secured by such assets has been paid in full, at
which point there may not be sufficient proceeds remaining to pay amounts due
on the exchange notes then outstanding.

Management discretion relating to certain business matters will be limited by
restrictive covenants contained in our indebtedness.

   Our credit facilities contain, and the indenture governing the exchange
notes contains, a number of restrictive covenants that will limit the
discretion of our management relating to certain business matters. We expect
that our future indebtedness will also contain similar restrictive covenants.
These covenants, among other things, will restrict our ability to incur
additional indebtedness, pay dividends and make other distributions, prepay
subordinated indebtedness, make investments and other restricted payments,
engage in mergers and consolidations, create liens, sell assets, and enter into
certain transactions with affiliates. There can be no assurance that such
covenants will not adversely affect our ability to finance our future
operations or capital needs or to engage in other business activities which may
be in the interests of our company.

                                       15
<PAGE>

We may not have sufficient funds to purchase the exchange notes as required
upon a change of control.

   The indenture governing the exchange notes contains provisions relating to
certain events constituting a change in control of Equinix. Upon the occurrence
of such a change in control, we will be required to make an offer to purchase
all outstanding exchange notes at a purchase price equal to 101% of their
aggregate principal amount, in addition to the accrued and unpaid interest, if
any, up to the purchase date. We cannot assure you that we would have
sufficient funds to pay the purchase price for exchange notes tendered by
holders seeking to accept such an offer to purchase. Our failure to purchase
all exchange notes validly tendered under such an offer to purchase would
result in an event of default under the indenture.

                           FORWARD-LOOKING STATEMENTS

   This prospectus contains forward-looking statements. These statements relate
to future events or our future financial performance. In some cases, you can
identify forward-looking statements by terminology--for instance, may, will,
should, expect, plan, anticipate, believe, estimate, predict, potential or
continue, the negative of these terms or other comparable terminology. These
statements are only predictions. Actual events or results may differ
materially. In evaluating these statements, you should specifically consider
various factors, including the risks outlined in the Risk Factors section.
These factors may cause our actual results to differ materially from any
forward-looking statement.

   Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. Moreover, neither we nor any other
person assumes responsibility for the accuracy and completeness of the forward-
looking statements. We are under no duty to amend this prospectus to update any
of the forward-looking statements after the date of this prospectus to conform
these statements to actual results or to changes in our expectations. However,
we will be subject to the reporting requirements of the Securities Exchange Act
of 1934, and as a result will file periodic current reports with the Securities
and Exchange Commission that will report all material changes to our business
as well as include material information to revise or correct any misleading
statements.

                             AVAILABLE INFORMATION

   We have filed a registration statement on Form S-4 with the Securities and
Exchange Commission covering the exchange notes, and this prospectus is part of
our registration statement. For further information on Equinix and the exchange
notes, you should refer to our registration statement and its exhibits. This
prospectus summarizes material provisions of contracts and other documents that
we refer you to. Since the prospectus may not contain all the information that
you may find important, you should review the full text of these documents. We
have included copies of these documents as exhibits to our registration
statement.

   In addition, the indenture requires that we file reports under the
Securities Exchange Act of 1934 with the Securities and Exchange Commission and
provide those reports to the trustee and holders of the notes. You can inspect
and copy at prescribed rates the reports and other information that we file
with the Securities and Exchange Commission at the public reference facilities
maintained by the Securities and Exchange Commission at Room 1024, Judiciary
Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549, and also at the regional
offices of the Securities and Exchange Commission located at 7 World Trade
Center, Suite 1300, New York, New York 10048 and the Citicorp Center at 500
West Madison Street, Suite 1400, Chicago, Illinois 60661-2511. You may obtain
information on the operation of the public reference facilities by calling the
Securities and Exchange Commission at 1-800-SEC-0330. The Securities and
Exchange Commission also maintains an internet web site at http://www.sec.gov
that contains reports, proxy and information statements and other information.
You can also obtain copies of such materials from us upon request.

   We have agreed that, whether or not we are required to do so by the rules
and regulations of the Securities and Exchange Commission, for so long as any
of the exchange notes remain outstanding, we will furnish you as a holder of
the exchange notes and will, if permitted, file with the Securities and
Exchange Commission (1) all quarterly and annual financial information that
would be required to be contained in a filing with the Securities and Exchange
Commission on Forms 10-Q and 10-K if we were required to file such forms,
including a "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and, relating to the annual information only, a report
thereon by our independent accountants, and (2) all reports that would be
required to be filed with the Securities and Exchange Commission on Form 8-K if
we were required to file such reports. In addition, for so long as any of the
exchange notes remain outstanding, we have agreed to make available to any
prospective purchaser of the exchange notes or beneficial owner of the notes in
connection with any sale of these notes the information required by Rule 144A
under the Securities Act.

                                USE OF PROCEEDS

   We will not receive any cash proceeds from the issuance of the exchange
notes in exchange for the outstanding initial notes. The exchange offer is
intended solely to satisfy certain of our obligations under the registration
rights agreement. In consideration for issuing the exchange notes, we will
receive initial notes in like aggregate principal amount.

   The net proceeds to us from the original issuance of the initial notes,
after deducting discounts, commissions, expenses and restricted cash were
approximately $156.4 million. We invested approximately $37.0 million of the
net proceeds in a portfolio of U.S. government securities, which were then
pledged as security for the payment in full of interest on the initial notes
through June 1, 2001. We intend to use the balance of such net proceeds for the
buildout of our IBX centers in the United States and abroad and for other
capital expenditures, working capital and general corporate purposes. In
addition, although we do not currently have any acquisitions contemplated or
pending, in the future we may use a portion of the proceeds for the acquisition
of businesses or assets. We currently intend to allocate substantial proceeds
to each of these uses. However, the precise allocation of funds among these
uses will depend on future technological, regulatory and other developments in
or affecting our business, the competitive climate in which we operate and the
emergence of future opportunities.

   We have invested such proceeds in U.S. government securities or other short-
term, interest bearing, investment grade securities. We are not currently and
do not expect as a result to become subject to the registration requirements of
the Investment Company Act of 1940, as amended. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."

                       CHANGE IN INDEPENDENT ACCOUNTANTS

   On March 7, 2000, KPMG LLP resigned as our independent accountants upon
determining that they may no longer be independent of Equinix as a result of
Cisco, Inc.'s investment in both KPMG Consulting, Inc., a subsidiary of KPMG
LLP and Equinix and we subsequently appointed PricewaterhouseCoopers LLP as our
principal accountants on March 21, 2000. There were no disagreements with the
former accountants during the fiscal years ended December 31, 1998 and 1999 or
during any subsequent interim period preceding their replacement on any matter
of accounting principles or practices, financial statement disclosure, or
auditing scope or procedures, which disagreements, if not resolved to the
former accountants' satisfaction, would have caused them to make reference to
the subject matter of the disagreement in connection with their reports. The
former independent accountants issued an unqualified report on the financial
statements as of December 31, 1999 and 1998 and for the year ended December 31,
1999 and the period from June 22, 1998 (inception) to December 31, 1998. For
purposes of this filing, the financial statements as of December 31, 1999 and
1998 and for the year ended December 31, 1999 and the period from June 22, 1998
(inception) to December 31, 1998 have been audited by PricewaterhouseCoopers
LLP. Prior to March 21, 2000, we did not consult with PricewaterhouseCoopers
LLP on items that involved our accounting principles or the form of audit
opinion to be issued on our financial statements. The change in accountants was
approved by our board of directors.

(1) Adjusted EBITDA consists of the net loss excluding interest, income taxes,
    depreciation and amortization of capital assets and amortization of
    deferred stock-based compensation. Adjusted EBITDA is presented to enhance
    an understanding of our operating results and is not intended to represent
    cash flow or results of operations in accordance with generally accepted
    accounting principles for the period indicated and may be calculated
    differently than adjusted EBITDA for other companies. Adjusted EBITDA is
    not a measure determined under generally accepted accounting principles nor
    is it a measure of liquidity.
(2) In calculating the ratio of earnings to fixed charges, earnings consist of
    net loss before income tax expense and fixed charges. Fixed charges consist
    of interest expense, and capitalized interest, amortized discounts and
    capitalized expenses related to indebtedness and an estimate of the
    interest within rental expense. The ratio of earnings to fixed charges was
    less than 1.0 to 1.0 for each of the periods presented. Earnings available
    for fixed charges were thus inadequate to cover fixed charges. The coverage
    deficiency for the period from June 22, 1998 (inception) to December 31,
    1998, the year ended December 31, 1999 and the three months ended March 31,
    1999 and 2000 was $1,019,700, $20,790,600, $1,344,900 and $18,008,800,
    respectively.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

   Equinix designs, builds and operates neutral IBX centers where Internet
businesses place their equipment and their network facilities in order to
interconnect with each other to improve Internet performance. Our neutral IBX
centers provide content providers, application service providers, or ASPs, and
e-commerce companies with the ability to directly interconnect with a choice of
bandwidth providers, Internet service providers, or ISPs, and site and
performance management companies. Equinix currently has IBX centers in the
Washington, D.C. metropolitan area, the New York metropolitan area and in
Silicon Valley. We intend to complete construction of five additional IBX
centers and seven expansion projects by May 2001, resulting in a total of eight
IBX centers in the U.S. and Europe. From our inception on June 22, 1998 through
December 31, 1999, our operating activities consisted primarily of designing
and building our first three IBX centers, searching for additional space for
IBX center expansion, developing our management team and raising private equity
and third party debt to fund the design and building of our IBX centers.

   We generate recurring revenues primarily from the leasing of cabinet space
and the provisioning of direct interconnections between our customers. In
addition, we intend to offer value-added services and professional services
including "Smart Hands" service for customer equipment installations and
maintenance. Customer contracts for the lease of cabinets, interconnections and
switch ports are renewable and typically range from one to three years with
payments for services made on a monthly basis. We entered into our first
customer contract in April 1999. In addition, we generate non-recurring
revenues which are comprised of installation charges that are billed upon
successful installation of our customer cabinets, interconnections and switch
ports. Both recurring and non-recurring revenues are recognized ratably over
the term of the contract.

   Cost of revenues consist primarily of rental payments on our IBX centers,
site employees' salaries and benefits, utility costs, amortization and
depreciation of IBX center build-out costs and equipment and engineering power,
redundancy and security systems support and services. We expect that our cost
of revenues will increase significantly as we continue our rollout of
additional IBX centers.

   Our selling, general and administrative expenses consist primarily of costs
associated with recruiting, training and managing new employees, salaries and
related costs of our operations, marketing and sales, customer fulfillment and
support functions costs and finance and administrative personnel and related
professional fees. Our current sales and marketing expenses, including sales
personnel, will increase significantly as we continue our rollout of additional
IBX centers into new domestic and international markets. We expect to
significantly increase our sales and marketing activities.

   We recorded deferred stock-based compensation of approximately $1.1 million,
$19.4 million and $4.9 million in connection with stock options granted during
1998, 1999 and the three months ended March 31, 2000, respectively, where the
deemed fair value of the underlying common stock was subsequently determined to
be greater than the exercise price on the date of grant. Approximately
$164,000, $6.6 million and $3.5 million was amortized to stock-based
compensation expense for the period and year ended December 31, 1998 and 1999,
respectively and the three months ended March 31, 2000, respectively. Options
granted are typically subject to a four year vesting period. We are amortizing
the deferred stock-based compensation on an accelerated basis over the vesting
periods of the applicable options in accordance with FASB Interpretation
No. 28. The remaining $15.1 million of deferred stock-based compensation at
March 31, 2000 will be amortized over the remaining vesting period. Based on
grants from April 1 through May 25, 2000, we expect to record additional
deferred stock-based compensation of approximately $33.5 million. As a result
of the cumulative effect of stock-based compensation, we expect stock-based
compensation expense, which is primarily attributable to amortization of
deferred stock-based compensation charges, to impact our reported results
through December 31, 2004. Based on option grants through May 25, 2000, we
expect stock-based compensation expense to be approximately $21.9 million for
the year ending December 31, 2000.


                                       22
<PAGE>

   A key aspect of our strategy is to capitalize on our first mover advantage
and to execute our rapid IBX center rollout program. The rollout of these
additional IBX centers will significantly increase both fixed and operating
expenses, including expenses associated with hiring, training and managing new
employees, leasing and maintaining additional IBX centers, power and redundancy
system engineering support and related costs, implementing security systems and
related costs and depreciation.

Results of Operations

   Since our inception in June 1998, we have experienced operating losses and
negative cash flows from operations in each quarter. As of March 31, 2000 we
had an accumulated deficit of $39.8 million. The revenue and income potential
of our business and market is unproven, and our short operating history makes
an evaluation of our business and prospects difficult. There can be no
assurance that we will ever achieve profitability on a quarterly or annual
basis or, if achieved, sustain such profitability.

Three Months Ended March 31, 1999 and 2000

   Revenues. We recognized revenues of $135,600 for the three months ended
March 31, 2000. Revenues consisted of recurring revenues of $124,200, primarily
from the leasing of cabinet space, and non-recurring revenue of $11,400 related
to the recognized portion of installation revenue. Installation and service
fees are recognized ratably over the term of the contract. We did not offer IBX
center colocation or interconnection exchange services during the three months
ended March 31, 1999, and as such, no revenues were recognized during that time
period.

   Cost of Revenues. Cost of revenues increased from $43,100 for the three
months ended March 31, 1999 to $3.3 million for the three months ended March
31, 2000, an increase of $3.3 million. Cost of revenues consists primarily of
rental payments for our leased IBX centers, site employees' salaries and
benefits, utility costs, power and redundancy system engineering support
services and related costs, security services and related costs and
depreciation and amortization of our IBX center buildout and other equipment
costs. As of March 31, 1999, we had not opened any IBX centers, but we had
incurred rent expense on the first IBX center. During the three months ended
March 31, 2000, we incurred expenses on our first three operational IBX
centers.

   Sales and Marketing. Sales and marketing expenses increased from $143,800
for the three months ended March 31, 1999 to $4.5 million for the three months
ended March 31, 2000, an increase of $4.4 million. Sales and marketing expenses
consist primarily of compensation and related costs for the sales and marketing
personnel, sales commissions, marketing programs, public relations, promotional
materials and travel. The increase in sales and marketing expense resulted from
the addition of personnel in our sales and marketing organizations, reflecting
our increased selling effort and our efforts to develop market awareness. Also
included in sales and marketing for the three months ended March 31, 1999 and
2000 are $28,500 and $1.4 million, respectively, of stock-based compensation
expense. We anticipate that sales and marketing expenses will increase in
absolute dollars as we increase our investment in these areas to coincide with
the rollout of additional IBX centers.

   General and Administrative. General and administrative expenses increased
from $1.2 million for the three months ended March 31, 1999 to $6.3 million for
the three months ended March 31, 2000, an increase of $5.1 million. General and
administrative expenses consist primarily of salaries and related expenses,
accounting, legal and administrative expenses, professional service fees and
other general corporate expenses. The increase in general and administrative
expenses was primarily the result of increased expenses associated with
additional hiring of personnel in management, finance and administration, as
well as other related costs associated with supporting the Company's expansion.
Also included in general and administrative for the three months ended March
31, 1999 and 2000 are $346,700 and $2.0 million, respectively, of stock-based
compensation expense.

   Interest Expense, net. For the three months ended March 31, 1999, we
reported interest income of $106,000 and interest expense of $32,200. For the
three months ended March 31, 2000, we reported net interest

                                       23
<PAGE>

expense of $4.0 million. Net interest for the three months ended March 31, 2000
consisted of interest income of $3.7 million offset by interest expense of $7.7
million. Interest income increased substantially due to higher cash, cash
equivalent and short-term investment balances held in interest bearing
accounts, resulting from the proceeds of the senior notes and preferred stock
financing activities. Interest expense for the three months ended March 31,
2000 is a result of the issuance of senior notes and increased debt facilities
and capital lease obligations and amortization of the senior notes debt
facilities and capital lease obligation discount.

 Period from Inception (June 22, 1998) through December 31, 1998 and Year Ended
 December 31, 1999

   Revenues. We recognized revenues of $37,100 for the year ended December 31,
1999. In addition, we entered into contracts with other customers and allocated
cabinet space to these customers as of December 31, 1999. Although we entered
into these customer contracts, we have not recognized such amounts as revenues
as the sales cycle was not yet complete by December 31, 1999. We did not offer
IBX center colocation or interconnection exchange services from inception
through December 31, 1998, and as such, no revenues were recognized from the
date of inception to December 31, 1998.

   Cost of Revenues. We incurred cost of revenues of $3.3 million for the year
ended December 31, 1999. Cost of revenues is primarily comprised of rental
payments for our leased IBX centers, site employees' salaries and benefits,
utilities costs, power and redundancy system engineering support services and
related costs, security services and related costs and depreciation and
amortization of our IBX center build-out and other equipment costs. We did not
offer IBX center colocation or interconnection exchange services from inception
through December 31, 1998, and as such, no cost of revenues were recorded from
the date of inception to December 31, 1998.

   Sales and Marketing. Sales and marketing expenses increased from $47,400 for
the period from the date of inception to December 31, 1998 to $3.9 million for
the year ended December 31, 1999. These expenses consist primarily of salary
and benefit costs from the hiring of both sales and marketing personnel and
certain related recruiting and relocation costs, the establishment of sales and
marketing programs and the recognition of stock-based compensation expense in
the amount of approximately $13,000 and $1.6 million for the period from the
date of inception to December 31, 1998 and the year ended December 31, 1999,
respectively. In addition, we established two regional sales offices to support
the New York and Washington, D.C. metropolitan area IBX centers. We anticipate
that sales and marketing expenses will increase substantially to coincide with
the commercial operation of our IBX centers and additional stock-based
compensation expense in the amount of approximately $9.0 million which will be
amortized over the applicable vesting periods.

   General and Administrative. General and administrative expenses increased
from $902,200 for the period from the date of inception to December 31, 1998 to
$12.6 million for the year ended December 31, 1999. General and administrative
expenses are primarily comprised of salaries and employee benefits expenses,
including stock-based compensation expense in the amount of approximately
$151,000 and $4.8 million for the period from the date of inception to December
31, 1998 and the year ended December 31, 1999, respectively, professional and
consultant fees and corporate headquarter operating costs, including facility
and other rental costs. We anticipate that general and administrative expenses
will increase significantly due to increased staffing levels consistent with
the growth in our infrastructure and related operating costs associated with
our regional and international expansion efforts and additional stock-based
compensation expense in the amount of approximately $12.7 million which will be
amortized over the applicable vesting periods.

   Interest Expense, net. Net interest expense increased from $70,100 for the
period from the date of inception to December 31, 1998 to $1.0 million for the
year ended December 31, 1999. We recognized interest income of $2.1 million for
the year ended December 31, 1999 compared to $150,000 for the period from
inception to December 31, 1998. Interest income increased substantially due to
higher cash, cash equivalent and short-term investment balances resulting from
the senior notes and preferred stock financing activities. Interest expense was
$3.1 million for the year ended December 31, 1999 compared to $220,000 for the
period from inception to December 31, 1998. Interest expense increased due to
the issuance of senior notes, increased debt

                                       24
<PAGE>

facilities and capital lease obligations and amortization of the senior notes
and debt facilities and capital lease obligation discount. Interest expense for
the period from inception to December 31, 1998 consisted of the interest charge
from the conversion right of the convertible loan arrangement, under which the
initial lenders to the Company converted their promissory notes into Series A
preferred stock at a more beneficial rate than other Series A investors.

Liquidity and Capital Resources

   From inception, we have financed our operations and capital requirements
primarily through the issuance of senior notes, the private sale of preferred
stock and debt financing for aggregate gross proceeds of approximately $397.0
million. Our principal source of liquidity as of March 31, 2000 consists of
$193.6 million in cash and cash equivalents and $6.9 million in debt and
capital lease facilities. As of March 31, 2000, our total indebtedness from our
senior notes, debt facilities and capital lease obligations was $213.7 million.

   Net cash used in operating activities was $796,000 for the period from
inception to December 31, 1998, $9.9 million for the year ended December 31,
1999 and $4.2 million for the three months ended March 31, 2000. We used cash
primarily to fund our net loss from operations.

   Net cash used in investing activities was $5.3 million for the period from
inception to December 31, 1998, $86.3 million for the year ended December 31,
1999 and $10.9 million for the three months ended March 31, 2000. Net cash used
in investing activities was primarily attributable to the construction of our
IBX centers and the purchase of restricted cash and short-term investments.

   Net cash generated by financing activities was $10.2 million for the period
from inception to December 31, 1998 and $295.2 million for the year ended
December 31, 1999. Net cash used in financing activities was $370,700 for the
three months ended March 31, 2000. The cash generated from financing activities
for the period from inception through December 31, 1998 was due to the sale of
Series A preferred stock. The cash generated by financing activities for the
year ended December 31, 1999 was primarily due to the issuance of senior notes,
proceeds from debt and capital lease facilities and proceeds from the issuance
of Series B preferred stock. Net cash used in financing activities during the
three months ended March 31, 2000 was primarily due to the repayment of debt
facilities and capital lease obligations, offset by proceeds from the exercise
of stock options.

   In March 1999, we entered into a loan and security agreement in the amount
of $7.0 million bearing interest at 7.5% to 9.0% per annum repayable in 36 to
42 equal monthly payments with a final interest payment equal to 15% of the
advance amounts due at maturity. In May 1999, we entered into a master lease
agreement in the amount of $1.0 million. This master lease agreement was
increased by addendum in August 1999 by $5.0 million. This agreement bears
interest at either 7.5% or 8.5% and is repayable over 42 months in equal
monthly payments with a final interest payment equal to 15% of the advance
amounts due on maturity. In August 1999, we entered into a loan agreement in
the amount of $10.0 million. This loan agreement bears interest at 8.5% and is
repayable over 42 months in equal monthly payments with a final interest
payment equal to 15% of the advance amounts due on maturity. At March 31, 2000,
we had total debt and capital lease financings available of $23.0 million, of
which we had drawn down $16.1 million.

   In December 1999, we issued $200.0 million aggregate principal amount of 13%
Senior Notes due 2007 for aggregate net proceeds of $193.4 million, net of
offering expenses. Of the $200.0 million gross proceeds, $16.2 million was
allocated to additional paid-in capital for the fair value of the common stock
warrants and recorded as a discount to the senior notes. Senior notes, net of
the unamortized discount, is $184.4 million as of March 31, 2000.

   In December 1999, we completed the private sale of our Series B preferred
stock, net of issuance costs, in the amount of $81.7 million.

   In May 2000, we completed the private sale of our Series C preferred stock
in the amount of $77.8 million.

                                       25
<PAGE>

   On May 23, 2000, we entered into an agreement to purchase real property in
San Jose, California for approximately $82.0 million. The sale is scheduled to
close on June 15, 2000 and we currently anticipate that a third party financier
will purchase the property at the closing and then we will lease this property
to us under a long-term lease. There can be no assurance that we will secure
this arrangement. If we are not able to secure this arrangement we have the
option to purchase the property directly. However, we do not intend to do so at
this time.

   We intend to complete construction of five additional IBX centers and
several expansion projects by the end of 2001, resulting in a total of eight
IBX centers in the U.S. and Europe. We intend to finance these IBX centers
through current cash flow from our existing IBX centers and approximately
$750.0 million of additional financing. As of May 31, 2000, we had $241.7
million in cash, cash equivalents and short-term investments available to us.
We anticipate that the funds currently available to us are sufficient to fund
the capital expenditure and working capital requirements, including operating
losses, associated with the initial rollout of seven IBX centers and two IBX
center expansion projects. To complete the implementation of our rollout plan
within our proposed time frame we anticipate that we will need to raise funds
through a combination of additional debt or equity financing. If we cannot
raise sufficient additional funds on acceptable terms, or in amounts required
by us, we may delay the rollout of additional IBX centers or permanently reduce
our rollout plans. If we are unable to raise additional funds to further our
rollout, we anticipate that the cash flow generated from the IBX centers, for
which we will have obtained financing, will be sufficient to meet the working
capital, debt service and corporate overhead requirements associated with those
IBX centers.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards, or SFAS, No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including derivative
instruments embedded in other contracts, and for hedging activities. SFAS No.
133, as amended by SFAS No. 137, Deferral of the Effective Date of FASB
Statement No. 133, is effective for all fiscal quarters of fiscal years
beginning after June 15, 2000. This statement does not currently apply to us
and we do not have any derivative instruments or hedging activities.

   In December 1999, the SEC issued Staff Accounting Bulletin 101, or SAB 101,
Revenue Recognition, which outlines the basic criteria that must be met to
recognize revenue and provides guidance for presentation of revenue and for
disclosure related to revenue recognition policies in financial statements
filed with the SEC. We believe the adoption of SAB 101 will not have a material
impact on our financial position and results of operations.

   In March 2000, the FASB issued Interpretation No. 44, Accounting for Certain
Transactions Involving Stock Compensation - an Interpretation of APB 25. This
Interpretation clarifies (a) the definition of employee for purposes of
applying Opinion 25, (b) the criteria for determining whether a plan qualifies
as a noncompensatory plan, (c) the accounting consequence of various
modifications to the terms of a previously fixed stock option or award, and (d)
the accounting for an exchange of stock compensation awards in a business
combination. This Interpretation is effective July 1, 2000, but certain
conclusions in this Interpretation cover specific events that occur after
either December 15, 1998, or January 12, 2000. To the extent that this
Interpretation covers events occurring during the period after December 15,
1998, or January 12, 2000, but before the effective date of July 1, 2000, the
effects of applying this Interpretation are recognized on a prospective basis
from July 1, 2000. We have not yet determined the impact, if any, of adopting
this interpretation.

Impact of the Year 2000

   We have not experienced any year 2000-related disruption in the operation of
our systems. Although most year 2000 problems should have become evident on
January 1, 2000, additional year 2000-related problems may become evident only
after that date.

Quantitative and Qualitative Disclosures About Market Risk

   Equinix has limited exposure to financial market risks, including changes in
interest rates. An increase or decrease in interest rates would not
significantly increase or decrease interest expense on debt obligations due to
the fixed nature of our debt obligations. Our interest income is sensitive to
changes in the general level of U.S. interest rates, particularly since the
majority of our investments are in short-term instruments. Due to the short-
term nature of our investments, we believe that we are not subject to any
material market risk exposure. Equinix does not currently have any foreign
operations and thus our exposure to foreign currency fluctuations is minimal.

   The fair market value of long-term fixed interest rate debt is subject to
interest rate risk. Generally, the fair market value of fixed interest rate
debt will increase as interest rates fall and decrease as interest rates rise.
The interest rate changes affect the fair market value but do not impact
earnings or cash flows. The effect of an immediate 10% change in interest rates
would not have a material impact on our future operating results or cash flows.
Fair values were determined from quoted market prices.

Overview

   Equinix designs, builds and operates neutral IBX centers where Internet
businesses place their equipment and their network facilities in order to
interconnect with each other to improve Internet performance. Our neutral IBX
centers place our customers' operations at a central location and provide them
with the highest level of security, multiple back-up services, flexibility to
grow and technical assistance. Our neutral IBX centers provide content
providers, ASPs and e-commerce companies with the ability to directly
interconnect with a choice of bandwidth providers, ISPs and site and
performance management companies. Content providers include those companies
that supply information, education or entertainment content such as
Excite@Home. ASPs include those companies that supply hosted applications to
enterprises over the Internet, such as Storage Networks. E-commerce companies
include those companies which conduct the sale of goods and services over the
Internet. ISPs provide Internet connectivity services and include companies
such as InterNAP and NorthPoint Communications Group. Bandwidth providers
include companies such as Worldcom and AT&T. Site and performance management
companies include one-stop Web presence integrators and content distribution
companies such as iBeam. Equinix IBX centers enable Internet companies to
quickly, easily and privately interconnect with a choice of business partners
and customers, providing them with the flexibility, speed and adaptability they
need to accelerate business growth.

   Equinix currently has IBX centers in the Washington, D.C. metropolitan area,
the New York metropolitan area and in Silicon Valley. We intend to complete
construction of five additional IBX centers and several expansion projects by
May 2001, resulting in a total of eight IBX centers in the U.S. and Europe. Our
customers include: Cable & Wireless, Concentric Network, Excite@Home, iBeam,
InterNAP, WorldCom, NorthPoint Communications Group, Onyx Networks, Teleglobe
and Storage Networks.

   We were incorporated in Delaware in June 1998. Two of our founders, Albert
M. Avery, IV, our president and chief operating officer, and Jay S. Adelson,
our chief technology officer, were responsible for designing, building and
operating the Palo Alto Internet Exchange, or PAIX, one of the first and most
active global Internet exchange points. PAIX launched commercial service in
July 1996 and was functioning at full capacity within one year of introduction.

   From inception, we have raised more than $397.0 million to fund the rollout
of our IBX centers. In April 1999, our first customer contract was signed and
we began recognizing revenue in December 1999. We have not yet been profitable
and expect to incur significant additional losses.

Market Opportunity

   Since the early 1990s, the Internet has experienced tremendous growth and is
emerging as a global medium for communications and commerce. According to
Forrester Research, the number of Internet sites worldwide is expected to grow
from fewer than 500,000 in 1997 to approximately 4.0 million in 2002. In
addition, according to International Data Corporation, worldwide Internet
business commerce sales are forecast to grow from approximately $50 billion at
the end of 1998 to approximately $1.3 trillion by the end of 2003.

   As a result of competitive pressures, Internet and e-commerce companies are
demanding facilities that provide multiple interconnections with a broad cross-
section of product and service providers and customers. The tremendous growth
of Internet usage and e-commerce has aggravated the inefficiencies of the
current Internet architecture, which has constrained businesses' abilities to
effectively grow and manage their Internet operations.

   As the Internet and Internet businesses experienced significant growth and
demand, and content providers emerged, vertically integrated hosting providers
evolved to provide these businesses with places to locate their equipment and
access the Internet. Until now, Internet businesses have had to rely on these
vertically integrated hosting providers for the distribution of content and
delivery of services between thousands of individual

                                       28
<PAGE>

networks. Internet and e-commerce companies who choose to colocate equipment at
these facilities typically have no choice but to purchase bandwidth from the
owner of the facility. Bandwidth is typically known as the rate at which data
flows over a network and is measured in bits per second. This can be costly,
given the lack of competition, and a significant risk if the facility owner's
network were to fail or have performance problems.

   As content becomes more critical, the choice of suppliers and direct
interconnection become increasingly important. Forrester Research predicts that
a combination of rapid Internet growth and increased outsourcing of Internet-
related services will create an acute need for Internet-related hosting and
colocation services, producing U.S. revenue growth from approximately $3.5
billion in the year 2000 to over $14 billion by 2003.

The Equinix Solution

   Equinix IBX centers provide the environment and services to meet the
challenges facing Internet businesses today. Our centers will provide a free
market environment where choice stimulates efficient business growth. Because
Internet companies have a broad choice of product and service providers, they
can increase their service offerings, deliver services more efficiently and
have access to a larger potential customer base. As a result, we are able to
provide the following key benefits to our customers:

   Choice. We believe that the ability of customers to choose among a variety
of product and service providers is the fundamental driver of dynamic growth in
commerce. By offering this crucial element of choice, our IBX centers are
designed to serve as a catalyst for our customers that creates synergy among
them and makes it possible for them to adapt their business models to
successfully scale, or keep pace, with the growth of each other and of the
Internet. Internet and e-commerce related businesses view the IBX center as a
forum to attract additional customers and diversify sources of supply for their
businesses.

   Opportunity to Increase Revenues and Reduce Costs. Our customers will have
access to a variety of potential business partners. Accordingly, our customers
will have a better opportunity to increase the size of their addressable
markets, accelerate revenue growth and improve the quality of their services at
our IBX centers. In addition, participants will be able to enhance their
ability to control costs by aggregating their service purchases at a single
location and through improved purchasing power.

   Scalability. Our IBX centers will both stimulate and support the efficient
growth of our customers. From a facility perspective, we construct our IBX
centers to be large enough to accommodate our customers' short- term needs, and
our plan is to maintain sufficient available expansion space to meet their
long-term growth needs where possible. In addition, through our global presence
we will have a broad capacity to meet customers' multi-market and multi-
geographic requirements. On an individual basis, customers are able to design
their own unique cabinet configurations within a shared or private cage
environment. As the need arises, customers can expand within their original
cage or upgrade into a cage which meets their expanded requirements. We predict
that customers will require this added capacity as they interconnect with each
other and expand their customer reach.

   Reliability. Our IBX design provides our customers with reliable and
disaster-resistant environments that are necessary for optimum Internet
commerce interconnection. We believe that the level of excellence and
consistency achieved in our IBX architecture and design results in premium,
secure, fault-tolerant exchanges. Our IBX centers are designed to offer our
customers redundant, high-bandwidth Internet connectivity through multiple
third-party connections. Additionally, our solutions include multiple layers of
physical security, scalable cabinet space availability, on-site trained staff
24 hours per day, 365 days per year, dedicated areas for customer care and
equipment staging, redundant AC/DC power systems and multiple other redundant,
fault-tolerant infrastructure systems.

Equinix Strategy

   Our objective is to provide content providers, ASPs and e-commerce companies
with the ability to directly interconnect with a choice of bandwidth providers,
ISPs, and site and performance management companies to

                                       29
<PAGE>

grow their business. Equinix IBX centers enable Internet companies to quickly,
easily and privately interconnect with a choice of business partners and
customers, providing them with the flexibility, speed and adaptability they
need to accelerate business growth and to allow a faster, more reliable
Internet. To accomplish this objective we are employing the following
strategies:

   Provide Customer Choice. We provide our customers with the freedom to choose
their preferred product and service providers. We call this a neutral
environment and it is one of the fundamental characteristics of an IBX center.
We believe this is a significantly improved approach compared with the current
Internet model because it offers customers increased value and reliability
based on the availability of multiple providers of needed services. In
traditional colocation or Web hosting environments, customers are often limited
to a single choice of network provider, site management company, or performance
management company. This limited choice can lead to single points of failure
for customers or a limited number of options to choose from for value added
services. The Equinix model of neutrality gives customers a wide range of
providers to choose from for each of the services they require for increased
Internet performance and reliability. For instance, in each IBX customers can
choose from multiple network providers, ISPs and Web management companies. The
ability to choose who they work with directly leads to better Internet business
performance due to the increased diversity and an improved overall total cost
of ownership since these suppliers are competing for the customers' business
within the IBX center. Our customers will benefit from a neutral environment
that stimulates efficient business growth through accelerated network
economics, or the value derived by a provider at an IBX center from being able
to sell its services to a locally-aggregated set of customers, created by the
efficient and rapidly growing interaction between Internet businesses.

   Manage Choice to Create Network Effect. To attract the widest choice of
Internet partners, it is important to provide a robust mix of leading companies
from a variety of businesses and services. This allows content providers, e-
commerce companies and ASPs the opportunity to interconnect with a wide variety
of companies. As a result of the IBX interconnection model, IBX participants
encourage their customers, suppliers and business partners to also come into
the IBX center. These customers, suppliers and business partners may also, in
turn, encourage their business partners to locate in IBX centers resulting in
additional customer growth. For example, a large financial site who may choose
to locate in an Equinix IBX may encourage a bandwidth provider, a site
management company or another content partner, like a financial news service,
to also locate in the same IBX. In turn, these bandwidth providers or content
partners will also bring their business partners to the IBX. This network
effect enhances the value of an IBX center with each new customer as
interconnections provide monthly recurring revenues.

   Leverage Strategically Scalable Centers. The network effect created by the
Equinix IBX model requires strategic scalability to support the dynamic IBX
growth environment. Our expansion plans are designed to meet the growth of our
customers. Our IBX centers will both stimulate and support the efficient growth
of our customers. From a facility perspective, we construct our IBX centers to
be large enough to accommodate our customers' short term needs, and our plan is
to maintain sufficient available expansion space to meet their long-term growth
needs where possible.

   Expand Globally and Capitalize on First-Mover Advantage. We believe that
capitalizing on our first mover advantage is essential to establishing
leadership in the rapidly developing neutral Internet business exchange market.
As a result, we currently plan to open additional IBX centers in the United
States and internationally. We believe the demand for our international IBX
centers and services will be significant due to the early stage of Internet
infrastructure deployment outside of the U.S.

   Establish Equinix as the Leading Brand for IBX Centers. We plan to establish
Equinix as the industry standard for the highest quality business to business
Internet exchanges. Through brand awareness and promotion we intend to create a
strong following among all top content providers, ASPs and e-commerce
companies. We believe that this strong brand awareness, combined with our
ability to provide the highest quality business to business marketplace
facilities and professional services will provide us with a competitive
advantage in our market.

                                       30
<PAGE>

   Leverage Blue-Chip Equity Owners. Our stockholders are some of the most
influential companies driving the development, operation and utilization of the
Internet. They provide us with invaluable technical and business insight,
industry contacts and customer relationships to help expedite the expansion of
our business. These stockholders include Artemis S.A., Bechtel Corp., Benchmark
Capital, The Carlyle Group, Cisco Systems and Reuters.

Customers

   Customers typically sign renewable contracts of one to three years in
length, often with options on additional space. Our current customers include
Cable & Wireless, Concentric Network, Excite@Home, iBeam, InterNAP, Worldcom,
NorthPoint Communications Group, Onyx Networks, Teleglobe and Storage Networks.
Additionally, InterNAP, WorldCom, NorthPoint Communications Group, Onyx
Networks, Excite@Home, Teleglobe and Storage Networks have signed multi-site
agreements.

   Historically, Internet businesses have been vertically integrated and
provided all services directly to their customers. These services typically
include marketing, access and Internet backbone connectivity, server hosting,
and other services such as e-mail and Usenet newsgroups. Continued rapid
growth, innovation, competition and scarce human resources have opened the door
for companies to specialize in core Internet services and outsourced other
elements of their business or product to suppliers. These specialized players
include:

  . content providers and e-commerce companies supplying information,
    education or entertainment content and conducting the sale of goods and
    services;

  . ASPs offering hosted applications over the Internet;

  . ISPs offering end-users Internet access and customer support;

  . bandwidth providers (telecommunications carriers); and

  . site and performance management companies which integrate and manage a
    customer's end-to-end web presence and performance.

   We consider these companies to be the core of our customer base and we offer
each customer a choice of business partners and solutions that are designed to
meet their unique and changing needs.

   We believe our IBX centers choice and neutrality that are important to
companies interested in the growth and reliability of the Internet. Equinix
does not compete with its customers and partners and offers choice within each
customer segment. We believe all Internet companies benefit from the choice of
a wide variety of Internet business partners because their business interaction
is greatly enhanced which can translate to new revenue sources, greater
efficiency and growth.

 We Believe the Additional Benefits to all Customer Segments Include:

  .  Expedited service delivery
  .  Scalable, flexible, fault-tolerant environment
  .  Cost savings through aggregating purchases and sales at a single
     location
  .  Minimize packet loss and latency, or time that elapses between a request
     for information and its arrival
  .  Ability to focus on core competencies
  .  Centralized market with access to dozens of potential customers and
     partners
  .  Proximity to service providers reduces operations, technology and
     marketing costs, quickens service deployment, and improves performance
  .  Multiple layers of physical security
  .  Elimination of capital investment for facilities
  .  24X7 on-site Internet and telecommunications-trained staff

Services

   Within our IBX centers, customers can place their equipment and interconnect
with a choice of Internet companies. Equinix also provides customized solutions
for customers looking to resell IBX space component as part of their complete,
one-stop shop solution.

   Cabinets. Customers have several choices for colocating their equipment.
They can place the equipment in an Equinix shared or private cage or customize
their space to build their own data center within an IBX center. Cabinets are
84 inches high, suitable for networking and server colocation. Cable trays
support cables between and among cabinets. Stationary or slide shelves and
enclosed cabinets are available upon request. As a customer's colocation
requirements increase, they can expand within their original cage or upgrade
into a cage that meets their expanded requirements.

   Shared Cages. A shared cage environment is designed for customers needing
less than ten full cabinets to house their equipment. Each cabinet in a shared
cage is individually secured with an advanced trackable electronic locking
system and the cage itself is secured with the biometric hand-geometry system.

   Private Cages. Customers that contract for a minimum of five full cabinets
can use a private cage to house their equipment. Private cages are also
available in larger full cabinet sizes. Each private cage is individually
secured with the biometric hand-geometry system.

   Data Centers. Customers interested in providing a hosting service or
colocation center have the option of outsourcing the design, construction and
management of the physical facility to Equinix. Each customer can customize the
cabinet configuration within the space they purchase from Equinix in order to
satisfy their specific customers' needs.

  Interconnection

   Physical Cross-Connect. Customers needing to directly connect to another IBX
customer can do so for a set price. Equinix leaves the choice of speed and
media type to the participants, based on their needs. Cross connections are
installed, delivered and tested by us within twenty-four hours of a customer's
request.

   Central Switching Fabric. Customers may choose to connect to our central
switching fabric rather than purchase a direct physical cross connection. With
a connection to this switch, a customer can aggregate multiple interconnects
over one physical wire instead of purchasing individual physical cross
connects.

   Direct Connections. Customers requiring a dedicated communications link may
directly connect to each other. Direct connections are Any Mode Any Speed,
which means they can include single-mode fiber, multi-mode fiber, and other
media upon request, as well as handle any speed required by the customer. These
cross connections are customized and terminated per customer instructions and
may be implemented within 24 hours of request.

  Value-Added Services

   Our IBX centers are staffed with Internet and telecommunications specialists
who are on-site and available 24 hours per day, 365 days per year. These
professionals are trained to perform installations of customer equipment and
cross connections.

   Core Infrastructure Services. Those customers with a port connection on the
central switching fabric have access to multiple core infrastructure services.
These services address critical intelligent networking requirements and assist
customers in improving the quality of their interconnection and traffic
exchange.

   "Smart Hands" Services. Our customers can take advantage of our professional
"Smart Hands" service, which gives customers access to our IBX staff for a
variety of troubleshooting tasks, when their own staff is not on site. These
tasks include power cycling, card swapping, and performing emergency equipment
replacement. Services are available on-demand or by customer contract.

IBX Design and Staffing

   Our IBX centers are designed to provide a state-of-the-art, secure, full-
service, neutral operating environment of a minimum of 900 cabinets, or 50,000
square feet, in the first-phase buildout for colocation of customer equipment.
The IBX centers are designed to provide specific and compelling improvements
over legacy facilities, including scalability to meet our customer's ongoing
growth, improved security, redundancy of all key infrastructure systems and
improved customer care. An IBX center is divided into six basic functional
areas--access, customer care, colocation, telecommunications access, mechanical
and power systems and operations.

   Access Area. The access area includes a bullet-resistant guard booth; a
welcome area, a hand-geometry enrollment station, and a mantrap to further
control access to the IBX center. All doors and access ways are secured with
biometric hand-geometry readers to ensure absolute identification and
authentication. All customers and Equinix employees entering an Equinix IBX
center must be cleared through this secured zone.

   Customer Care Area. The customer care area includes a seating section,
conference rooms, Internet workstations, customer equipment preparation work
areas, equipment lockers, a game room, bathrooms, showers and a kitchen.

   Colocation Area. The colocation area is divided into large cages to house
networking and customer computer equipment that is secured by biometric
security access systems. This area includes dual independent AC and DC power
distribution systems, full-automated CCTV digital camera security surveillance,
and a tamper-proof overhead cable-management system with separate trays for
fiber and copper data, AC power and DC power cables. Access to the colocation
area is through the customer care area.

                                       33
<PAGE>

   Telecommunications Access Area. All IBX centers will have a minimum of two
dedicated fiber entry vaults for telecommunications carrier access to the
colocation area. In addition, every IBX center has roof space or a separate
platform for customers who access the IBX center via wireless devices such as
satellite dishes, radio antennae and microwave.

   Mechanical and Power Systems Area. The mechanical and power systems area
includes machine rooms and space used to house all mechanical, power safety and
security equipment. Fully redundant heating, ventilation, air conditioning and
power systems, as well as dual electric utility feeds support all areas of the
IBX center. Power systems are designed and periodically tested to transparently
handle rapid transition from public utility power to back-up power. The AC
uninterruptable power supply and DC battery systems are configured to operate a
fully occupied IBX center for a minimum of fifteen minutes. If there is a
utility power failure, the on-site generator system could be brought on-line in
less than eight seconds through an automatic transfer switch to supply
seamless, uninterrupted power to the IBX center. The emergency generators,
located in a specially equipped area, supply power to the AC and DC systems.
On-site fuel tanks store sufficient fuel to power a fully occupied IBX center
for a minimum of 48 hours.

   Operations Area. The operations area houses the IBX manager's office, an
operations center for staff technicians and office space for visiting Equinix
employees. It includes consoles for monitoring all IBX environmental systems
and for tracking all activities at the IBX center. In selected IBX centers,
this area will house regional operations centers that will monitor the
operations of several IBX centers.

 Additional Specifications

   Security System. All access controls and other security functions are
connected to a central security computer system that controls access to the
interior and exterior perimeters of the IBX centers. An armed security guard
located behind the bullet-resistant security console controls access to the
colocation area. The caged sections of the colocation area can only be accessed
through hand-geometry readers located on cage doors. Digital cameras connected
to a central system at the security console monitor and record all activity
within the IBX center, as well as the perimeter and the roof.

   Staffing. A typical IBX center is staffed with nine Equinix employees,
including one IBX manager and eight technical service personnel who provide 24
hours per day, 365 days per year coverage for customer support needs. In
addition, an IBX facility has two armed security guards on duty at all times, a
chief engineer and 24-hour technical support.

   Other. For security purposes, an Equinix IBX center is anonymous. No
indications of center ownership or function are visible from the exterior. In
addition, there are no raised floors and all walls are airtight and without
windows. Our IBX centers are designed with advanced fire suppression systems
which are armed with sensory mechanisms to sample the air and raise alarms
before pressurization or release. Finally, an Equinix IBX center is designed to
withstand a seismic event of 7.5 as measured on the Richter scale.

IBX Rollout Schedule

   The objective of our global rollout strategy is to rapidly establish a
leadership position in the mission critical Internet and e-commerce markets.
Equinix currently has IBX centers in the Washington, D.C. metropolitan area,
the New York metropolitan area and in Silicon Valley. We intend to complete
construction of five additional IBX centers and several expansion projects by
May 2001, resulting in a total of eight IBX centers in the U.S. and Europe. The
scalable nature of our IBX model enables us to be flexible in response to
changing market opportunities. As a result, the timing and placement of our IBX
centers will vary depending on numerous factors, including customer need,
technological and other developments.

   In November 1999, the Company entered into a definitive agreement with
WorldCom whereby WorldCom agreed to install high-bandwidth local connectivity
services to the Company's first seven IBX centers by a pre-determined date in
exchange for a warrant to purchase 675,000 shares of common stock of the
Company at

                                       34
<PAGE>

$0.67 per share (the "WorldCom Warrant"). The WorldCom Warrant is immediately
exercisable and expires five years from the date of grant. As of March 31,
2000, warrants for 187,500 shares are subject to repurchase at the original
exercise price if WorldCom's performance commitments are not completed.

   In November 1999, the Company entered into a master agreement with Bechtel
Corporation, or Bechtel, whereby Bechtel agreed to act as the exclusive
contractor under a Master Agreement to provide program management, site
identification and evaluation, engineering and construction services to build
approximately 29 IBX centers over a four year period under mutually agreed upon
guaranteed completion dates. As part of the agreement, the Company granted
Bechtel a warrant to purchase 352,500 shares of the Company's common stock at
$1.00 per share (the "Bechtel Warrant"). The Bechtel Warrant is immediately
exercisable and expires five years from date of grant. As of March 31, 2000,
warrants for 281,988 shares are subject to repurchase at the original exercise
price, if Bechtel's performance commitments are not complete.

Sales and Marketing

 Sales

   We use a direct sales force to market our services to Internet and e-
commerce related businesses. We are organizing our sales force by customer
segments as well as establishing a sales presence in diverse geographic
regions, which will enable efficient servicing of the customer base from a
network of regional offices. A regional office is comprised of a manager, sales
representatives and technical support personnel. We also have reseller
agreements with several large customers. These distribution channels will
account for a smaller portion of our business by design. In addition, our sales
team will work closely with each customer to foster the natural network effect
of our IBX model, resulting in access to a wider potential customer base via
our existing customers. As a result of the IBX interconnection model, IBX
participants encourage their customers, suppliers and business partners to also
come into the IBX. These customers, suppliers and business partners also, in
turn, encourage their business partners to locate in IBX centers resulting in
additional customer growth. This network effect significantly reduces Equinix's
customer acquisition costs.

   Before opening an IBX center, we secure key anchor customers and focus on
generating sales commitments for at least 20% of the available capacity. Our
sales strategy is to target the top 25 companies in our customer segments,
which include content providers, ASPs, e-commerce companies, carriers, ISPs and
site and performance management companies. Momentum in the selling process and
the presence of anchor customers are important to attracting additional
potential customers who see the IBX center as an opportunity to generate new
customers and revenues. We expect a substantial number of customers to contract
for services at multiple IBX centers and have already received orders from such
customers. At each IBX center, our sales representatives will screen
prospective customers and will manage the population of the IBX center to
ensure an appropriate mix of customer types.

 Marketing

   To support our sales effort and to actively promote and solidify the Equinix
brand, we plan to conduct comprehensive marketing programs. Our marketing
strategies will include an active public relations campaign, print
advertisements, online advertisements, trade shows, speaking engagements,
strategic partnerships and on-going customer communications programs. We are
focusing our marketing effort on business and trade publications, online media
outlets, industry events and sponsored activities. We participate in a variety
of Internet, computer and financial industry conferences and encourage our
officers and employees to pursue speaking engagements at these conferences. In
addition to these activities, we intend to build recognition through sponsoring
or leading industry technical forums and participating in Internet industry
standard-setting bodies.

Competition

   Our market is new, rapidly evolving, and likely to have an increasing number
of competitors. To be successful in this emerging market, we must be able to
sufficiently differentiate our IBX model from existing

                                       35
<PAGE>

colocation and web hosting companies. We may also face competition from persons
seeking to replicate our IBX concept. We may not be successful in
differentiating ourselves or achieving widespread market acceptance of our
business. Furthermore, enterprises that have already invested substantial
resources in peering arrangements may be reluctant or slow to adopt our
approach that may replace, limit or compete with their existing systems. If we
are unable to complete our IBX centers in a timely manner, other companies will
be able to attract the same customers that we are targeting. Once the customers
are located in our competitors' facilities, it will be very difficult, if not
impossible, to convince them to relocate to our IBX centers.

   We may encounter competition from a number of sources, some of which may
also be our customers, including:

  . vertically integrated Web site hosting, colocation and ISP companies such
    as AboveNet, Exodus, GlobalCenter and Globix;

  . established communications carriers such as AT&T, Level 3, WorldCom and
    Qwest; and

  . emerging colocation service providers such as Colo.com, CO Space and
    Telehouse.

   Potential competitors may bundle their products or incorporate colocation
services in a manner that is more attractive to our potential customers than
purchasing cabinet space in our IBX centers and utilizing our services.
Furthermore, new competitors or alliances among competitors may emerge and
rapidly acquire significant market share. Our competitors may be able to
respond more quickly to new or emerging technologies and changes in customer
requirements than we can.

   Some of our potential competitors have longer operating histories and
significantly greater financial, technical, marketing and other resources than
we do. In particular, carriers and several hosting and colocation companies
have extensive customer bases and broad customer relationships that they can
leverage, including relationships with many of our potential customers. These
companies also have significantly greater customer support and professional
service capabilities than we do. Because of their greater financial resources,
some of these companies have the ability to adopt aggressive pricing policies.
As a result, in the future we may have to adopt pricing strategies that compete
with such competitors to attract and retain customers. Any such pricing
pressures would adversely affect our ability to generate revenues.

Employees

   As of March 31, 2000, we had 136 full-time employees and 21 full-time
consultants. We had 104 employees based at our corporate headquarters in
Redwood City, California and our regional sales offices in New York, NY and
Reston, VA. Of those employees, 28 were in engineering and operations, 48 were
in sales and marketing and 28 were in management and finance. In addition, we
had 32 employees based at our Washington, D.C., New York, NY and Silicon Valley
IBX centers.

Properties

   Our executive offices are currently located in Redwood City, CA and after
August 2000 will be located in Mountain View, CA. We have entered into lease
commitments for IBX centers in Ashburn, VA, Newark, NJ, San Jose and Los
Angeles, CA, Chicago, IL and Dallas, TX and Amsterdam, The Netherlands.
Relating to future IBX centers, we do not intend to own real estate or
buildings but rather continue to enter into lease agreements with a minimum
term of ten years, renewal options and rights of first refusal on space for
expansion.

Legal Proceedings

   We are currently not involved in any litigation.

(1) Each of Messrs. Avery and Adelson purchased 3,030,000 shares of restricted
    stock on June 22, 1998 in accordance with a stock purchase agreement. Each
    agreed to amend his stock purchase agreement on July 30, 1998 to subject
    2,727,000 of the shares to vesting restrictions. Pursuant to the amendment,
    the 2,727,000 shares will vest in 48 monthly installments from June 22,
    1998. The purchaser will also vest in 25% of the shares if his employment
    is involuntarily terminated and will vest in all of the shares if his
    employment is involuntarily terminated within 12 months following a change
    in control of Equinix. As of December 31, 1999, Messrs. Avery and Adelson
    had each vested in 1,022,625 of the restricted shares and the restricted
    shares had a value of $8,180,489 which represents 1,704,375 unvested shares
    valued at $4.80 per share less $0.0003, the price paid per share. On May
    15, 2000, our board of directors agreed to waive our repurchase right with
    respect to all of Mr. Avery's unvested shares. As a result, Mr. Avery
    currently holds 2,580,000 fully vested shares of our common stock.

Option Grants in Last Fiscal Year

   We have not granted stock options or appreciation rights to any of the Named
Executive Officers during the fiscal year ended December 31, 1999.

Aggregated Option Exercises in Last Fiscal Year and Fiscal Year-End Option
Values

   None of the Named Executive Officers exercised options during the fiscal
year ended December 31, 1999 and none of the Named Executive Officers held any
options at the end of the fiscal year.

Employee Benefit Plan

 1998 Stock Plan

   Share Reserve. Our board of directors adopted our 1998 Stock Plan on
September 10, 1998. Our stockholders have also approved this plan. We have
reserved 15,012,810 shares of our common stock for issuance under the 1998
Stock Plan. In general, if options or shares awarded under the 1998 Stock Plan
are forfeited, then those options or shares will again become available for
awards under the 1998 Stock Plan.

   Administration. Our board of directors administers the 1998 Stock Plan. The
board has the complete discretion to make all decisions relating to the
interpretation and operation of our 1998 Stock Plan. The board has the
discretion to determine who will receive an option, what type of option it will
be, how many shares will be covered by the option, what the vesting
requirements will be, if any, and what the other features and conditions of
each option will be. The board may also reprice outstanding options and modify
outstanding options in other ways.

                                       40
<PAGE>

   Eligibility. The following groups of individuals are eligible to participate
in the 1998 Stock Plan:

  . Employees;

  . Non-employee members of our board of directors; and

  . Consultants.

   Types of Awards. The 1998 Stock Plan provides for the following types of
awards:

  . Incentive stock options to purchase shares of our common stock;

  . Nonstatutory stock options to purchase shares of our common stock; and

  . Restricted stock.

   Options. An optionee who exercises an incentive stock option may qualify for
favorable tax treatment under Section 422 of the Internal Revenue Code of 1986.
However, nonstatutory stock options do not qualify for such favorable tax
treatment. The exercise price for incentive stock options granted under the
1998 Stock Plan may not be less than 100% of the fair market value of our
common stock on the option grant date. In the case of nonstatutory stock
options, the minimum exercise price is 85% of the fair market value of our
common stock on the option grant date. Optionees may pay the exercise price by
using:

  . Cash;

  . Shares of common stock that the optionee already owns;

  . An immediate sale of the option shares through a broker designated by us;
    or

  . A loan from a broker designated by us, secured by the option shares.

   Options vest at the time or times determined by our board of directors. In
most cases, our options will vest over a four-year period following the date of
grant. Options generally expire 10 years after they are granted, however they
generally expire earlier if the optionee's service terminates earlier.

   Restricted Shares. Restricted shares may be awarded under the 1998 Stock
Plan in return for:

  . Cash;

  . Services previously provided to us; and

  . Services to be provided to us in the future, except that the par value of
    such shares, if newly issued, shall be paid in cash.

Restricted shares vest at the time or times determined by the board.

   Change in Control. If a change in control of Equinix occurs, an option or
restricted stock award under the 1998 Stock Plan will generally become fully
vested. However, if the surviving corporation assumes the option stock award or
option or replaces it with a comparable option, then vesting will not
accelerate. An option or stock award will become fully exercisable and fully
vested if the holder's employment or service is involuntarily terminated within
12 months following the change in control. A change in control includes:

  . A merger or consolidation of Equinix with or into another entity or any
    other corporate reorganization, if persons who were not our shareholders
    immediately before the transaction own immediately after the transaction
    50% or more of the voting power of the outstanding securities of each of
    (a) the continuing or surviving entity and (b) any direct or indirect
    parent corporation of such continuing or surviving entity; after which
    our own stockholders own 50% or less of the surviving corporation, or its
    parent company; or

  . A sale of all or substantially all of our assets.


                                       41
<PAGE>

   Amendments or Termination. Our board of directors may amend or terminate the
1998 Stock Plan at any time. If our board amends the plan, stockholder approval
is not required unless such approval is otherwise required under applicable
law. The 1998 Stock Plan will continue in effect until September 9, 2008,
unless the board decides to terminate the plan earlier.

Employment Agreements and Change of Control Arrangements

   The board of directors, as plan administrator of the 1998 Stock Plan, has
the authority to provide for accelerated vesting of the shares of common stock
subject to outstanding options held by our officers and any other person in
connection with certain changes in control of Equinix. In connection with our
adoption of the 1998 Stock Plan, we have provided that upon a change in control
of Equinix, each outstanding option and all shares of restricted stock will
generally become fully vested unless the surviving corporation assumes the
option or award or replaces it with a comparable award.

   None of our executive officers have employment agreements with us, and their
employment may be terminated at any time. Our form offer letter for officers
provides for an additional 12 months of vesting if we are acquired or upon a
change in control, provided such officer is still employed on the date of
acquisition.

   We have delivered an offer letter to Peter F. Van Camp, our chief executive
officer, dated April 25, 2000, which provides that his salary shall be $310,000
per year. The letter provides for the grant of an option to purchase 3,105,000
shares of common stock at the fair market value on the grant date vesting over
four years. The letter provides that we will extend a no-interest loan to Mr.
Van Camp for up to $3,000,000 to purchase a primary residence. The loan will be
secured by Mr. Van Camp's primary residence and any shares of stock that Mr.
Van Camp obtains by exercising the options described above. The letter also
provides for reimbursement of up to $80,000 of relocation expenses. The letter
further provides for 12 months of severance pay if Mr. Van Camp is terminated
by us for reasons other than cause or disability. We have also entered into a
stock option agreement with Mr. Van Camp, which provides that our right to
repurchase unvested shares shall lapse upon certain changes in control of
Equinix.

   Equinix has also delivered an offer letter to Philip J. Koen, our chief
financial officer and corporate development officer, dated July 9, 1999, which
provides that his salary shall be $195,000 per year. The letter provides that
we will grant him an option to purchase 660,000 shares of common stock at the
fair market value on the grant date vesting over four years. The letter further
provides for six months of severance pay if Mr. Koen is terminated by us for
reasons other than cause.

   We have also delivered an offer letter to Peter T. Ferris, our vice
president of sales, dated June 28, 1999, which provides that his salary shall
be $190,000 per year and he is eligible for a target bonus of $60,000. The
letter provides for the grant of an option to purchase 510,000 shares of common
stock at the fair market value on the grant date vesting over four years. The
letter also provides that we will extend a no-interest loan to Mr. Ferris of up
to $750,000 to purchase his primary residence. The loan will be secured by Mr.
Ferris' primary residence and any shares of stock that Mr. Ferris obtains by
exercising the options described above. The letter also provides for
acceleration of vesting of option shares as if Mr. Ferris remained employed for
one additional year if there are certain changes in control of Equinix. We also
agreed to indemnify Mr. Ferris for any claims brought by his former employer
under an employment and non-compete agreement he had with that employer.

   On May 15, 2000, our board of directors agreed to waive our repurchase right
with respect to all of Albert M. Avery, IV's unvested shares. As a result, Mr.
Avery currently holds 2,580,000 fully vested shares of our common stock.

     of May 31, 2000.

                       DESCRIPTION OF OTHER INDEBTEDNESS

Venture Lending & Leasing Equipment Acquisition Loan Facility

   In August 1999, we entered into a $10.0 million equipment acquisition loan
facility with Venture Lending & Leasing, Inc. II, as the agent and principal
lender. The facility lenders will make advances up to:

  . 85% of the acquisition cost of the equipment and tenant improvements for
    our Newark, New Jersey IBX center; and

  . 100% of the acquisition cost, to the extent that such cost does not
    exceed $1.0 million, of certain customer acquisition and serving software
    that we acquire for our headquarters.

Our obligations under the facility are secured by a first priority security
interest against the assets financed with the facility advances and the
customer acquisition and serving software that the facility lenders have agreed
to finance. We can request facility advances until June 2000. As of March 31,
2000 we have drawn the entire $10.0 million against this loan facility.

   Interest will accrue on the facility advances at the annual rate of 8.5%,
and the advances will be repaid in 42 equal monthly installments. In connection
with the last installment we will pay a final amount equal to 15% of the
original advance amount. We will have the right to prepay the advances, in
whole or in part, provided that we pay a prepayment premium equal to the
following percentage of the principal prepaid:

       <S>                                                          <C>

       31-36.......................................................    3%
       37-42.......................................................    2%
</TABLE>

   In connection with this facility, we issued to the lenders warrants to
purchase Series A preferred stock at an exercise price of $3.00 per share. In
total, 300,000 shares can be acquired under the warrants, for an aggregate
exercise price equal to 9% of the facility commitment. The fair value of these
warrants, as determined using an option pricing model, has been recorded as a
deferred debt facility cost and will be amortized to interest expense on a
straight-line basis over the term of the facility.

   The facility contains customary covenants that restrict our operations
relating to, among other things, incurring debt, granting security interests,
merging or consolidating with other entities, making loans and investments,
entering into affiliate transactions and changing our business. It does not
have any financial covenants. The facility contains customary events of
default, including non-payment of amounts due under the facility, default under
certain of our other obligations, breach of covenants set forth in the
facility, the existence of certain unstayed or undischarged judgments, the
making of materially false or misleading representations or warranties, the
commencement of reorganization, bankruptcy, insolvency or similar proceedings,
the occurrence of certain ERISA events or certain change of control events.

Comdisco Equipment Lease Facility

   In May 1999, we entered into a $1.0 million equipment lease finance facility
with Comdisco, Inc. In August 1999, Comdisco amended this facility and
increased its total lease financing commitment by $5.0 million.

   Under the original $1.0 million commitment, which we can draw down through
May 2000, Comdisco will lease to us equipment, software and tenant improvements
for our corporate headquarters, on the condition that the dollar amount of the
software and tenant improvements financed does not exceed 20% of this
commitment. Each lease schedule under this commitment is for 42 months, with
monthly lease payments in the amount of

                                       47
<PAGE>

2.698% of the acquisition cost of the leased property, for an implied annual
interest rate of 16.2%. When the term for a schedule covering equipment
expires, we will have the option of returning the leased property to Comdisco,
negotiating with Comdisco for an extension of the lease term or purchasing the
property at its then fair market value, to the extent that such value does not
exceed 15% of the equipment's original acquisition cost. When the term for a
schedule covering software and tenant improvements expires, we must make a
final payment equal to 15% of the original acquisition cost of the software and
tenant improvements. As of March 31, 2000, we have leased a total of $661,000
in equipment under this facility.

   Under the $5.0 million increased commitment, which we can draw down until
August 2000, Comdisco will lease to us equipment, software and tenant
improvements for our San Jose, California IBX center, provided that the dollar
amount of the software and tenant improvements financed does not exceed 57% of
this commitment. Each lease schedule under this commitment is for 42 months,
with monthly lease payments in the amount of 2.742% of the acquisition cost of
the leased property, for an implied annual interest rate of 8.5%. Upon
executing a lease schedule, we must pay the first and last months rent in
advance. When the term for a schedule covering the San Jose IBX center expires,
we must make a final payment equal to 15% of the original acquisition cost of
the property financed under the schedule. To date, we have not leased any
amount under this commitment.

   In connection with the original $1.0 million lease commitment, we issued to
Comdisco a warrant to acquire 30,000 shares of Series A preferred stock at a
purchase price of $1.67 per share, as adjusted to reflect a three-for-two
forward split of our capital stock effected on January 19, 2000. In connection
with the $5.0 million increase in the facility commitment, we issued to
Comdisco a warrant to acquire 150,000 shares of Series A preferred stock at a
purchase price of $3.00 per share, as adjusted to reflect a three-for-two
forward split of our capital stock effected on January 19, 2000. The fair value
of these warrants, as determined using an option pricing model, has been
recorded as a deferred debt facility cost and will be amortized on a straight-
line basis to interest expense over the term of the facility.

   The facility restricts our ability to merge or consolidate with another
entity. It does not contain any financial covenants. The facility contains
customary equipment lease events of default, including non-payment of amounts
due under the facility, breach of covenants set forth in the facility, the
making of materially false or misleading representations or warranties under
the facility, and the commencement of reorganization, bankruptcy, insolvency or
similar proceedings involving us.

Comdisco Equipment Loan Facility

   In March 1999, Equinix-DC, Inc., our wholly owned subsidiary and the
operator of our Washington, D.C. IBX center, entered into a $7.0 million
equipment acquisition loan facility with Comdisco, Inc. Until March 2000,
Comdisco will make advances up to 100% of the acquisition cost of equipment,
tenant improvements and software for our Washington, D.C. IBX center, provided
that no more than 57% of the loan commitment may be used to finance tenant
improvements and software. Comdisco holds a first priority security interest in
all of Equinix-DC's assets as collateral for the facility obligations.

   Advances that finance equipment acquisitions will accrue interest at the
annual rate of 7.5% and will be repaid in 42 monthly installments, and in
connection with the last installment we will pay a final amount equal to 15% of
the original advance amount. Advances that finance tenant improvements and
software acquisitions will accrue interest at the annual rate of 9% and will be
repaid in 36 monthly installments. In connection with the last installment, we
will pay a final amount equal to 15% of the original advance amount. We will
have the right to prepay the advances, in whole or in part, without paying any
penalty or premium. As at March 31, 2000, we have borrowed a total of $5.5
million under this facility. The remaining portion of the facility was drawn in
April 2000.

   In connection with this facility, we issued to Comdisco a warrant to acquire
765,000 shares of our Series A preferred stock at a purchase price of $0.67 per
share, as adjusted to reflect a three-for-two forward split of our capital
stock effected on January 19, 2000. The fair value of these warrants, as
determined using an

                                       48
<PAGE>

option pricing model, has been recorded as a deferred debt facility cost and
will be amortized on a straight-line basis to interest expense over the term of
the facility.

   The facility contains covenants that restrict Equinix-DC's right to, among
other things, grant security interests, declare dividends, dispose of a
material portion of its assets, and enter into settlements with customers
relating to outstanding accounts. It does not have any financial covenants. The
facility contains customary events of default, including non-payment of amounts
due under the facility, default by Equinix-DC relating to certain of its other
obligations, breach of covenants set forth in the facility, the existence of
certain unstayed or undischarged judgments against Equinix-DC, the making of
materially false or misleading representations or warranties under the
facility, and the commencement of reorganization, bankruptcy, insolvency or
similar proceedings involving Equinix-DC.

Fore Financial Services Equipment Lease Facility

   In June 1999, we entered into an equipment lease facility with Fore
Financial Services. Under the first lease schedule, we leased $197,440 in
equipment and software for our corporate headquarters. We are required to make
36 monthly lease payments of $5,943. Upon expiration of the initial lease term,
the term can be extended for another 6 months, or we can purchase the leased
property at its then fair market value. Under the second lease schedule, we
leased $208,298 in equipment and software for the Washington, D.C. IBX center.
We are required to make 36 monthly lease payments of $6,270. Upon expiration of
the initial lease term, the term can be extended for another 6 months, or we
can purchase the leased property at its then fair market value. Under the third
lease schedule, we leased $210,300 in equipment and software for our Newark,
New Jersey IBX center, effective November 1999. We are required to make 36
monthly lease payments of $6,379. Upon the expiration of the initial lease
term, the term can be extended for another 6 months, or we can purchase the
lease property at its then fair market value. Under the fourth lease schedule,
we leased $195,500 in equipment and software for our Silicon Valley, California
IBX center, effective February 2000. We are required to make 36 monthly lease
payments of $6,037. Upon the expiration of the initial lease term, the term can
be extended for another 6 months, or we can purchase the lease property at its
then fair market value.

   The facility restricts our ability to merge or consolidate with another
entity or to sell all or substantially all of our assets, by treating such
events as defaults. It does not contain any financial covenants. The facility
contains customary equipment lease events of default, including non-payment of
amounts due under the facility, breach of covenants set forth in the facility,
the making of materially false or misleading representations or warranties
under the facility, and the commencement of reorganization, bankruptcy,
insolvency or similar proceedings involving us.

Cisco Systems Credit Corporation Lease Facility

   In March 1999, we entered into an equipment lease facility with Cisco
Systems Credit Corporation. Under this facility, we have leased, for a 24-month
term, $137,293 in Cisco and Cisco-related equipment for our corporate
headquarters. We paid the first and last months' rent payments upon signing the
lease schedule. Each rent payment is $5,463. When the term expires, we will
have the option to purchase the leased property at its then fair market value.
The option will terminate, however, if default occurs during the term. If we do
not purchase the leased property, we will have the right to extend the lease
term in one-year increments with the same monthly payments.

   The facility contains customary equipment lease events of default, including
non-payment of amounts due under the facility, breach of covenants set forth in
the facility and the commencement of reorganization, bankruptcy, insolvency or
similar proceedings involving us.

                               THE EXCHANGE OFFER

Purpose of the Exchange Offer

   Under the registration rights agreement, we are required to use our
reasonable best efforts to file not later than February 29, 2000, 90 days
following the date of original issuance of the initial notes, the registration
statement of which this prospectus is a part for a registered exchange offer
relating to an issue of new notes. The date of the original issuance of the
initial notes is also referred to as the "closing date". The new notes will be
substantially identical in all material respects to the initial notes except
that the new notes will be registered under the Securities Act, will not bear
legends restricting their transfer and will not be entitled to registration
rights under the registration rights agreement. This summary of provisions of
the registration rights agreement does not purport to be complete and we refer
you to the provisions of the registration rights agreement, which has been
filed as an exhibit to the registration statement of which this prospectus is a
part and a copy of which is available as described under the heading "Available
Information."

   Under the registration rights agreement, we are required to:

  . use our reasonable best efforts to cause the registration statement to be
    declared effective no later than June 28, 2000, 210 days after the
    closing date;

  . use our reasonable best efforts to consummate the exchange offer within
    30 days of the registration statement being declared effective; and

  . keep the exchange offer effective for not less than 30 days, or longer if
    required by applicable law, after the date that notice of the exchange
    offer is mailed to holders of the initial notes.

   The exchange offer being made here, if commenced and consummated within the
time periods described in this paragraph, will satisfy those requirements under
the registration rights agreement.

   This prospectus, together with the letter of transmittal, is being sent to
all record holders of initial notes as of June 16, 2000.

   Based on interpretations by the staff of the Securities and Exchange
Commission, as set forth in no-action letters issued to third parties, we
believe that the exchange notes issued in the exchange offer may be offered for
resale, resold or otherwise transferred by each holder of exchange notes, other
than a broker-dealer who acquires the initial notes directly from Equinix for
resale under Rule 144A under the Securities Act or any other available
exemption under the Securities Act, and other than any holder that is an
"affiliate," as defined in Rule 405 under the Securities Act, of Equinix,
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such holder:

  . is acquiring the exchange notes in the ordinary course of its business;

  . is not participating in, and does not intend to participate in, a
    distribution of such exchange notes within the meaning of the Securities
    Act and has no arrangement or understanding with any person to
    participate in a distribution of the exchange notes within the meaning of
    the Securities Act; and

  . is not an affiliate, as defined in Rule 405 under the Securities Act, of
    Equinix.

   By tendering the initial notes in exchange for exchange notes, each holder,
other than a broker-dealer, will be required to make representations to that
effect. If a holder of initial notes is participating in or intends to
participate in, a distribution of the exchange notes, or has any arrangement or
understanding with any person to participate in a distribution of the exchange
notes to be acquired in the exchange offer, such holder may be deemed to have
received restricted securities and may not rely on the applicable
interpretations of the staff of the Securities and Exchange Commission. Any
such holder will have to comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any secondary resale
transaction.

   Each broker-dealer that receives exchange notes for its own account in
exchange for initial notes may be deemed to be an "underwriter" within the
meaning of the Securities Act and must acknowledge that it will

                                       50
<PAGE>

deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such exchange notes. The letter of transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. This prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with offers to
resell, resales and other transfers of exchange notes received in exchange for
initial notes which were acquired by such broker-dealer as a result of market
making or other trading activities. We have agreed that we will make this
prospectus available to any broker-dealer for a period of time not to exceed
180 days after the consummation of the exchange offer for use in connection
with any such offer to resell, resale or other transfer. Please refer to the
section in this prospectus entitled "Plan of Distribution."

Shelf Registration Statement

   In the event that:

  . because of any change in law or its applicable interpretations by the
    staff of the Securities and Exchange Commission, we are not permitted to
    effect the exchange offer;

  . for any other reason, the exchange offer is not consummated within 210
    days from the closing date; or

  . any holder of initial notes notifies us within 20 business days following
    the consummation of the exchange offer that (a) such holder was
    prohibited by law of policy of the Securities and Exchange Commission
    from participating in the exchange offer, or (b) such holder may not
    resell the exchange notes acquired by it in the exchange offer to the
    public without delivering a prospectus and this prospectus is not
    appropriate or available for such resale, or (c) such holder is a broker-
    dealer and holds notes acquired directly from us or any of our
    affiliates, within the meaning of the Securities Act;

  we will be obligated, at our sole expense, to:

  . use our reasonable best efforts, as promptly as practicable and in no
    event more than 30 days following such request, to file with the
    Securities and Exchange Commission a shelf registration statement
    covering resales of the initial notes;

  . use our reasonable best efforts to cause the shelf registration statement
    to be declared effective under the Securities Act within 90 days after
    the date we are required to file a shelf registration statement; and

  . use our reasonable best efforts to keep the shelf registration statement
    continuously effective, supplemented and amended as required by the
    Securities Act to permit the prospectus which is a part of such shelf
    registration statement to be usable by holders for a period of two years
    after the shelf registration statement is declared effective or such
    shorter period of time that will terminate when all of the applicable
    initial notes have been sold thereunder.

   We will, in the event that a shelf registration statement is filed, provide
to each holder of the initial notes being registered copies of the prospectus
that is a part of the shelf registration statement, notify each such holder
when the shelf registration statement has become effective and take certain
other actions as are required to permit unrestricted resales of the initial
notes being registered. A holder that sells initial notes under the shelf
registration statement will be required to be named as a selling security
holder in the related prospectus and to deliver a prospectus to purchasers,
will be subject to certain of the civil liability provisions under the
Securities Act in connection with such sales and will be bound by the
provisions of the registration rights agreement that are applicable to such a
holder, including certain indemnification rights and obligations.

Liquidated Damages

   In the event that:

  . we do not file the registration statement or the shelf registration
    statement, as the case may be, with the Securities and Exchange
    Commission on or before the dates specified above for such filings;

                                       51
<PAGE>

  . the registration statement or the shelf registration statement, as the
    case may be, is not declared effective on or before the dates specified
    above for such effectiveness;

  . the exchange offer is not consummated within 30 days of the registration
    statement being declared effective; or

  . the shelf registration statement is filed and declared effective but
    thereafter ceases to be effective or usable in connection with its
    intended purpose;

each such event a "Registration Default," then we will be obligated to pay to
each holder of transfer restricted securities, as defined in the registration
rights agreement, liquidated damages. Liquidated damages will accrue and be
payable semi-annually on the initial notes and the exchange notes, in addition
to the stated interest on the initial notes and the exchange notes, in an
amount equal to 0.50% per year during the first 90-day period, which will
increase by 0.50% per year for each subsequent 90-day period, but in no event
will such rate exceed 1.50% per year in the aggregate, regardless of the number
of registration defaults. Liquidated damages will accrue from the date a
registration default occurs until the date on which:

  . the registration statement is filed;

  . the registration statement or shelf registration statement is declared
    effective and the exchange offer is consummated;

  . the shelf registration statement is declared effective; or

  . the shelf registration statement again becomes effective or made usable,
    as the case may be.

   Following the cure of all registration defaults, the accrual of liquidated
damages will cease.

   Upon consummation of the exchange offer, subject to certain exceptions,
holders of initial notes who do not exchange their initial notes for exchange
notes in the exchange offer will no longer be entitled to registration rights
and will not be able to offer or sell their initial notes, unless such initial
notes are subsequently registered under the Securities Act, which, subject to
certain limited exceptions, we will have no obligation to do, or under an
exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. Please refer to the section in this
prospectus entitled "Risk Factors--There could be negative consequences to you
if you do not exchange your initial notes for exchange notes."

Expiration of the Exchange Offer

   The exchange offer will expire at 5:00 p.m., New York City time, on July 17,
2000. The expiration date will be at least 30 days after the commencement of
the exchange offer in accordance with Rule 14e-1(a) under the Securities
Exchange Act of 1934 and the registration rights agreement.

Procedures for Tendering Initial Notes

   To tender your initial notes in the exchange offer, you must complete, sign
and date the letter of transmittal, or a facsimile of the letter of
transmittal, have the signatures thereon guaranteed if required by the letter
of transmittal, and mail or otherwise deliver the letter of transmittal or the
facsimile, or an agent's message, as defined below, together with the
certificates representing the initial notes being tendered and any other
required documents, to the exchange agent on or before 5:00 p.m., New York City
time, on the expiration date. Alternatively, you may either:

  . send a timely confirmation of a book-entry transfer of such initial
    notes, if such procedure is available, into the exchange agent's account
    at The Depository Trust Company, or DTC, following the procedure for
    book-entry transfer described below, on or before 5:00 p.m. on the
    expiration date; or

  . comply with the guaranteed delivery procedures described below.

                                       52
<PAGE>

   The term "agent's message" means a message, transmitted by DTC to, and
received by, the exchange agent and forming a part of a book-entry
confirmation, which states that DTC has received an express acknowledgment from
the participant in DTC tendering initial notes which are the subject of such
book-entry confirmation that such participant has received and agrees to be
bound by the terms of the letter of transmittal, and that we may enforce such
agreement against such participant.

   The method of delivery of the initial notes, the letter of transmittal and
all other required documents is at your election and risk. Instead of delivery
by mail, we recommend that you use an overnight or hand-delivery service. If
such delivery is by mail, we recommend that you use registered mail, properly
insured, with return receipt requested. In all cases, you should allow
sufficient time to assure timely delivery. You should not send any letters of
transmittal or initial notes to us. You must deliver all documents to the
exchange agent at its address set forth below. You may also request your
respective brokers, dealers, commercial banks, trust companies or nominees to
effect such tender on your behalf.

   Your tender of initial notes will constitute an agreement between you and us
in accordance with the terms and subject to the conditions set forth in this
prospectus and in the letter of transmittal.

   Only a holder of initial notes may tender such initial notes in the exchange
offer. The term "holder" relating to the exchange offer means any person in
whose name initial notes are registered on our books or any other person who
has obtained a properly completed bond power from the registered holder.

   If you are the beneficial owner of initial notes that are registered in the
name of a broker, dealer, commercial bank, trust company or other nominee and
you wish to tender your initial notes, you should contact such registered
holder promptly and instruct such registered holder to tender on your behalf.
If you wish to tender on your own behalf, you must, before completing and
executing the letter of transmittal and delivering your initial notes, either
make appropriate arrangements to register ownership of the initial notes in
your name or obtain a properly completed bond power from the registered holder.
The transfer of registered ownership may take considerable time.

   Signatures on a letter of transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by a member firm of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor" institution within the meaning of Rule
17Ad-15 under the Securities Exchange Act of 1934, each, an "eligible
institution", unless the initial notes are tendered:

  . by a registered holder, or by a participant in DTC whose name appears on
    a security position listing as the owner, who has not completed the box
    entitled "Special Issuance Instructions" or "Special Delivery
    Instructions" on the letter of transmittal if the exchange notes are
    being issued directly to such registered holder, or deposited into the
    participant's account at DTC; or

  . for the account of an eligible institution.

   If the letter of transmittal is signed by the recordholder(s) of the initial
notes tendered, the signature must correspond with the name(s) written on the
face of the initial notes without alteration, enlargement or any change
whatsoever. If the letter of transmittal is signed by a participant in DTC, the
signature must correspond with the name as it appears on the security position
listing as the holder of the initial notes.

   If the letter of transmittal is signed by a person other than the registered
holder of any initial notes listed, such initial notes must be endorsed or
accompanied by bond powers and a proxy that authorize such person to tender the
initial notes on behalf of the registered holder in satisfactory form to us as
determined in our sole discretion, in each case as the name of the registered
holder or holders appears on the initial notes.

   If the letter of transmittal or any initial notes or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or

                                       53
<PAGE>

representative capacity, such persons should so indicate when signing. Unless
waived by us, evidence satisfactory to us of their authority to so act must
also be submitted with the letter of transmittal.

   A tender will be deemed to have been received as of the date when the
tendering holder's duly signed letter of transmittal accompanied by the initial
notes tendered, or a timely confirmation received of a book-entry transfer of
initial notes into the exchange agent's account at DTC with an agent's message,
or a notice of guaranteed delivery from an eligible institution is received by
the expiration date. Issuances of exchange notes in exchange for initial notes
tendered under a notice of guaranteed delivery by an eligible institution will
be made only against delivery of the letter of transmittal, and any other
required documents, and the tendered initial notes, or a timely confirmation
received of a book-entry transfer of initial notes into the exchange agent's
account at DTC with an agent's message, with the exchange agent.

   All questions as to the validity, form, eligibility, including time of
receipt, acceptance and withdrawal of the tendered initial notes will be
determined by us in our sole discretion, which determination will be final and
binding. We reserve the absolute right to reject any and all initial notes not
properly tendered or any initial notes which, if accepted, would, in our
opinion or our counsel's opinion, be unlawful. We also reserve the absolute
right to waive any conditions of the exchange offer or irregularities or
defects in tender as to particular initial notes. Our interpretation of the
terms and conditions of the exchange offer, including the instructions in the
letter of transmittal, will be final and binding on all parties. Unless waived,
any defects or irregularities in connection with tenders of initial notes must
be cured within such time as we shall determine. We, the exchange agent or any
other person will be under no duty to give notification of defects or
irregularities relating to tenders of initial notes. None of us or the exchange
agent will incur any liability for failure to give such notification. Tenders
of initial notes will not be deemed to have been made until such irregularities
have been cured or waived. Any initial notes received by the expiration date
that are not properly tendered and as to which the defects or irregularities
have not been cured or waived will be returned without cost by the exchange
agent to the tendering holders of such initial notes, unless otherwise provided
in the letter of transmittal, as promptly as practicable following the
expiration date.

   In addition, we reserve the right in our sole discretion, subject to the
provisions of the indenture, to:

  . purchase or make offers for any initial notes that remain outstanding
    after the expiration date, or, as set forth under "--Expiration Date", to
    terminate the exchange offer in accordance with the terms of the
    registration rights agreement; and

  . to the extent permitted by applicable law, purchase initial notes in the
    open market, in privately negotiated transactions or otherwise. The terms
    of any such purchases or offers could differ from the terms of the
    exchange offer.

Acceptance of Initial Notes for Exchange; Delivery of Exchange Notes

   Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will accept all initial notes properly tendered, promptly after the
expiration date, and will issue the exchange notes promptly after the
expiration date and acceptance of the initial notes. Please refer to the
section of this prospectus entitled "--Conditions" below. For purposes of the
exchange offer, initial notes will be deemed to have been accepted as validly
tendered for exchange when, as and if we had given oral or written notice to
the exchange agent.

   In all cases, issuance of exchange notes for initial notes that are accepted
for exchange in the exchange offer will be made only after timely receipt by
the exchange agent of certificates for such initial notes or a timely book-
entry confirmation of such initial notes into the exchange agent's account at
the book-entry transfer facility, a properly completed and duly executed letter
of transmittal or an agent's message and all other required documents, in each
case, in form satisfactory to us and the exchange agent. If any tendered
initial notes are not accepted for any reason set forth in the terms and
conditions of the exchange offer or if initial notes are submitted for a
greater principal amount than the holder desires to exchange, such unaccepted
or non-exchanged initial notes will be returned without expense to the
tendering holder, or, in the case

                                       54
<PAGE>

of initial notes tendered by book-entry transfer procedures described below,
such non-exchanged initial notes will be credited to an account maintained with
such book-entry transfer facility, as promptly as practicable after withdrawal,
rejection of tender, the expiration date or earlier termination of the exchange
offer.

Book-Entry Transfer

   The exchange agent will make a request to establish an account relating to
the initial notes at DTC for purposes of the exchange offer. Any financial
institution that is a participant in DTC's systems may make book-entry delivery
of initial notes by causing DTC to transfer such initial notes into the
exchange agent's account at DTC in accordance with DTC's procedures for
transfer.

   However, although delivery of initial notes may be effected through book-
entry transfer into the exchange agent's account at DTC, an agent's message or
the letter of transmittal or facsimile of the letter of transmittal with any
required signature guarantees and any other required documents must, in any
case, be transmitted to and received by the exchange agent at the address set
forth below under "--Exchange Agent" on or before the expiration date or the
guaranteed delivery procedures described below must be complied with. Delivery
of documents to DTC does not constitute delivery to the exchange agent. All
references in the prospectus to deposit of initial notes will be deemed to
include DTC's book-entry delivery method.

Guaranteed Delivery Procedure

   If you are a registered holder of initial notes and desire to tender such
initial notes, and the initial notes are not immediately available, or time
will not permit your initial notes or other required documents to reach the
exchange agent before the expiration date, or the procedures for book-entry
transfer cannot be completed on a timely basis and an agent's message
delivered, you may still tender in the exchange offer if:

  .  you tender through an eligible institution;

  .  before the expiration date, the exchange agent receives from such
     eligible institution a properly completed and duly executed letter of
     transmittal, or facsimile of the letter of transmittal, and notice of
     guaranteed delivery, substantially in the form provided by us, by
     facsimile transmission, mail or hand delivery, setting forth your name
     and address as holder of the initial notes and the amount of initial
     notes tendered, stating that the tender is being made thereby and
     guaranteeing that within five business days after the expiration date
     the certificates for all tendered initial notes, in proper form for
     transfer, or a book-entry confirmation with an agent's message, as the
     case may be, and any other documents required by the letter of
     transmittal will be deposited by the eligible institution with the
     exchange agent; and

  .  the certificates for all tendered initial notes, in proper form for
     transfer, or a book-entry confirmation as the case may be, and all other
     documents required by the letter of transmittal are received by the
     exchange agent within five business days after the expiration date.

Withdrawal of Tenders

   Except as otherwise provided in this prospectus, you may withdraw tenders of
initial notes at any time before 5:00 p.m., New York City time, on the
expiration date.

   For a withdrawal to be effective, you must send a written or facsimile
transmission notice of withdrawal to the exchange agent before 5:00 p.m., New
York City time, on the expiration date at the address set forth below under "--
Exchange Agent" and before acceptance for exchange by us. Any such notice of
withdrawal must:

  .  specify the name of the person, or "depositor", having tendered the
     initial notes to be withdrawn ;

  .  identify the initial notes to be withdrawn, including, if applicable,
     the registration number or numbers and total principal amount of such
     initial notes;

                                       55
<PAGE>

  . be signed by the depositor in the same manner as the original signature
    on the letter of transmittal by which such initial notes were tendered,
    including any required signature guarantees, or be accompanied by
    documents of transfer sufficient to permit the trustee relating to the
    initial notes to register the transfer of such initial notes into the
    name of the depositor withdrawing the tender;

  . specify the name in which any such initial notes are to be registered, if
    different from that of the depositor; and

  . if applicable because the initial notes have been tendered following the
    book-entry procedures, specify the name and number of the participant's
    account at DTC to be credited, if different than that of the depositor.

   All questions as to the validity, form and eligibility, including time of
receipt, of such notices will be determined by us and our determination will be
final and binding on all parties. Any initial notes so withdrawn will be deemed
not to have been validly tendered for exchange for purposes of the exchange
offer. Any initial notes which have been tendered for exchange which are not
exchanged for any reason will be returned to their holder without cost to such
holder, or, in the case of initial notes tendered by book-entry transfer into
the exchange agent's account at DTC following the book-entry transfer
procedures described above, such initial notes will be credited to an account
maintained with DTC for the initial notes, as promptly as practicable after
withdrawal, rejection of tender, expiration date or earlier termination of the
exchange offer. Properly withdrawn initial notes may be retendered by following
one of the procedures described under "--Procedures for Tendering" and "--Book-
Entry Transfer" above at any time on or before the expiration date.

Conditions

   Notwithstanding any other term of the exchange offer, we will not be
required to accept initial notes for exchange, or issue exchange notes in
exchange for any initial notes, if:

  . a change in the current interpretation of the staff of the Securities and
    Exchange Commission has occurred which current interpretation permits the
    exchange notes issued in the exchange offer in exchange for the initial
    notes to be offered for resale, resold or otherwise transferred by their
    holders, other than in certain circumstances; or

  . a law has been adopted or enacted which, in our judgment, would
    reasonably be expected to impair our ability to proceed with the exchange
    offer.

   These conditions are for our sole benefit and may be asserted by us
regardless of the circumstances giving rise to any such condition or may be
waived by us, in whole or in part, at any time and from time to time, before
the expiration date, if we determine in our reasonable discretion that any of
the foregoing events or conditions has occurred or exists or has not been
satisfied, subject to applicable law. Our failure at any time to exercise any
of the foregoing rights will not be deemed a waiver of any such right and each
such right will be deemed an ongoing right which we may assert at any time and
from time to time before the expiration date.

   If we determine that we may terminate the exchange offer, as provided above,
we may:

  . refuse to accept any initial notes and return any initial notes that have
    been tendered to their holders;

  . extend the exchange offer and retain all initial notes tendered before
    the expiration date, subject to the rights of such holders of tendered
    initial notes to withdraw their tendered initial notes; or

  . waive such termination event relating to the exchange offer and accept
    all properly tendered initial notes that have not been withdrawn or
    otherwise amend the terms of the exchange offer in any respect as
    provided under the section in this prospectus entitled "--Expiration
    Date; Extensions; Amendments; Termination."

                                       56
<PAGE>

   The exchange offer is not conditioned upon any minimum principal amount of
initial notes being tendered for exchange.

   We have no obligation to, and will not knowingly, permit acceptance of
tenders of initial notes from our affiliates, within the meaning of Rule 405
under the Securities Act, or from any other holder or holders who are not
eligible to participate in the exchange offer under applicable law or its
interpretations by the Securities and Exchange Commission, or if the exchange
notes to be received by such holder or holders of initial notes in the exchange
offer, upon receipt, will not be tradable by such holder without restriction
under the Securities Act and the Securities Exchange Act of 1934 and without
material restrictions under the "blue sky" or securities laws of substantially
all of the states of the United States.

Accounting Treatment

   We will record the exchange notes at the same carrying value as the initial
notes, as reflected in our accounting records on the date of the exchange.
Accordingly, we will not recognize any gain or loss for accounting purposes. We
will amortize the costs of the exchange offer and the unamortized expenses
related to the issuance of the exchange notes over the term of the exchange
notes.

Exchange Agent

   We have appointed State Street Bank and Trust Company of California, N.A. as
exchange agent for the exchange offer. All questions and requests for
assistance and requests for additional copies of this prospectus or the letter
of transmittal should be directed to the exchange agent as follows:

Fees and Expenses

   We will bear the expenses of soliciting tenders in the exchange offer. The
principal solicitation for tenders in the exchange offer is being made by mail;
however, our offices and regular employees may make additional solicitations by
telegraph, telephone, telecopy or in person.

   We will not make any payments to brokers, dealers or other persons
soliciting acceptances of the exchange offer. However, we will pay the exchange
agent reasonable and customary fees for its services and will reimburse the
exchange agent for its reasonable out-of-pocket expenses in connection with the
exchange offer. We may also pay brokerage houses and other custodians, nominees
and fiduciaries the reasonable out-of-pocket expenses incurred by them in
forwarding copies of the prospectus, letters of transmittal and related
documents to the beneficial owners of the initial notes, and in handling or
forwarding tenders for exchange.

                                       57
<PAGE>

   We will pay the expenses incurred in connection with the exchange offer,
including fees and expenses of the exchange agent and trustee and accounting,
legal, printing and related fees and expenses.

   We will pay all transfer taxes, if any, applicable to the exchange of
initial notes in the exchange offer. However, the amount of any such transfer
taxes, whether imposed on the registered holder or any other persons, will be
payable by the tendering holder if:

  . certificates representing exchange notes or initial notes for principal
    amounts not tendered or accepted for exchange are to be delivered to, or
    are to be registered or issued in the name of, any person other than the
    registered holder of the initial notes tendered;

  . tendered initial notes are registered in the name of any person other
    than the person signing the letter of transmittal; or

  . a transfer tax is imposed for any reason other than the exchange of
    initial notes in the exchange offer.

   If satisfactory evidence of payment of such taxes or exemption therefrom is
not submitted with the letter of transmittal, the amount of such transfer taxes
will be billed directly to such tendering holder.

The Failures to Participate in the Exchange Offer will have Adverse
Consequences

   If you do not exchange your initial notes for exchange notes in the exchange
offer, you will not be able to resell, offer to resell or otherwise transfer
the initial notes unless they are registered under the Securities Act or unless
you resell them, offer to resell or otherwise transfer them under an exemption
from the registration requirements of, or in a transaction not subject to, the
Securities Act. In addition, you will no longer be able to obligate us to
register the initial notes under the Securities Act except in the limited
circumstances provided under the registration rights agreement. The
restrictions on transfer of your initial notes arise because we issued the
initial notes under exemptions from, or in transactions not subject to, the
registration requirements of the Securities Act and applicable state securities
laws. In addition, if you want to exchange your initial notes in the exchange
offer for the purpose of participating in a distribution of the exchange notes,
you may be deemed to have received restricted securities, and, if so, will be
required to comply with the registration and prospectus delivery requirements
of the Securities Act in connection with any resale transaction. To the extent
the initial notes are tendered and accepted in the exchange offer, the trading
market, if any, for the initial notes would be adversely affected. Please refer
to the section in this prospectus entitled "Risk Factors."

                       DESCRIPTION OF THE EXCHANGE NOTES

General

   The form and terms of the exchange notes are the same as the form and terms
of the initial notes, except that the exchange notes have been registered under
the Securities Act and therefore will not bear legends restricting their
transfer. We issued the initial notes and will issue the exchange notes under
an indenture, dated as of December 1, 1999, between Equinix and State Street
Bank and Trust Company of California, N.A., as trustee. The terms of the
exchange notes will include those stated in the indenture and those made part
of the indenture by reference to the Trust Indenture Act of 1939, as amended.
The exchange notes will be subject to all such terms, and holders are referred
to the indenture and the Trust Indenture Act for a statement of those terms.
Except as otherwise indicated, the following summary description of the
material provisions of the indenture relates both to the initial notes and the
exchange notes. We urge you to read the indenture because it, and not this
description, defines your rights as holder of the exchange notes. We have filed
copies of the indenture, escrow agreement and registration agreement as
exhibits to the registration statement which includes this prospectus. The
definitions of certain terms used in the following summary are set forth below
under "--Certain Definitions." For purposes of this summary, the term "Equinix"
refers only to Equinix, Inc. and not to any of its subsidiaries. Also, in this
description "initial notes" and "exchange notes" are collectively referred to
as the "notes."

   As of the Issue Date, all of our Subsidiaries will be Restricted
Subsidiaries. Under certain circumstances, we will be able to designate
existing or future Subsidiaries as Unrestricted Subsidiaries. Unrestricted
Subsidiaries will not be subject to many of the restrictive covenants contained
in the indenture.

Overview

   The notes will mature on December 1, 2007. Interest on the notes will be
payable semi-annually in arrears on each June 1 and December 1, commencing on
June 1, 2000. The exchange notes will bear interest from the most recent date
to which interest has been paid on the initial notes.

   We have deposited with an escrow agent cash to acquire U.S. government
securities totaling approximately $37.0 million that, together with the
proceeds from their investment, will be sufficient to pay, when due, the first
three interest payments on the notes, with us retaining any balance. The notes
will be collateralized by a first priority security interest in the escrow
account. Except for the security interest in the escrow account, the notes will
be general unsecured obligations and will rank without preference with all of
our other existing and future senior unsecured indebtedness. The notes will
also be effectively subordinated to all our existing and future secured
indebtedness to the extent of the value of the assets that secure such
indebtedness and to all of our subsidiaries' existing or future indebtedness,
whether or not secured.

   Generally, we may not redeem the notes before December 1, 2003. On or after
December 1, 2003, we may redeem the notes, in whole or in part, at any time, at
the redemption prices set forth below under "Option Redemption" together with
accrued and unpaid interest, if any, to the redemption date.

   Absent special circumstances, we cannot be required to redeem the notes.
However, in the event of a "Change of Control" as defined below, each holder
will have the right to require us to repurchase its notes at a repurchase price
equal to 101% of the aggregate principal amount of such notes, plus accrued and
unpaid interest, if any, through the date of repurchase.

   The indenture will limit:

  .  the selling of our assets or the stock of our subsidiaries;

  .  the payment of dividends on, and repurchase or redemption of, our
     capital stock and our subsidiaries' capital stock and the repurchase or
  redemption of our subordinated obligations;

  .  our making of investments;

  .  the incurrence of additional indebtedness or preferred stock by us and
     our subsidiaries;

                                       59
<PAGE>

  .  the incurrence of additional liens;

  .  our ability to permit restrictions to exist on the ability of our
     subsidiaries to pay dividends or make payments to us;

  .  our ability to engage in consolidations, mergers and transfers of all or
     substantially all of our assets; and

  .  transactions with our affiliates.

   All of these limitations and prohibitions are subject to a number of
important qualifications and exceptions. See "Certain Covenants."

   In addition, the indenture defines certain events of default. See "Events of
Default and Remedies." In the event of default, the trustee or the holders of
at least 25% in principal amount of the then outstanding notes may declare all
principal of, premium, if any, on, and interest on the notes to be due and
payable immediately.

Terms of Notes

   Except as set forth under "--Escrow Account; Disbursement of Funds," the
notes will be our senior unsecured obligations, ranking equally in right of
payment with all our other existing and future senior debt and senior to all
our existing and future subordinated debt. Holders of our secured Indebtedness,
however, will have claims that are before the claims of the holders relating to
the assets securing such other debt, except to the extent the notes are equally
and ratably secured by such assets. The indenture will permit us to incur
certain secured debt.

   The notes will be effectively subordinated to all Indebtedness and other
liabilities and commitments, including trade payables and lease obligations, of
our subsidiaries, including any Guarantees of such subsidiaries. Any right of
ours to receive assets of any of our subsidiaries in the event of its
liquidation or reorganization, and the consequent right of the holders to
participate in those assets, will be effectively subordinated to the claims of
that subsidiary's creditors. To the extent that we are recognized as a creditor
of such subsidiary, our claims would still be subordinate to any secured claim
to the assets of such subsidiary and any Indebtedness of such subsidiary that
is senior to that held by us.

Principal, Maturity and Interest

   The notes will be limited in aggregate principal amount to $200,000,000 and
will mature on December 1, 2007. Interest on the notes will accrue at the rate
of 13% per annum and will be payable semi-annually in arrears on June 1 and
December 1, commencing on June 1, 2000, to holders as of the immediately
preceding May 15 and November 15. Interest on the notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from the date of original issuance. Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months. Principal, premium,
if any, and interest on the notes will be payable at the office or agency of
Equinix maintained for such purpose in New York city or, at the option of
Equinix, payment of interest on the notes may be made by check mailed to the
holders at their respective addresses set forth in the register of holders.
Until otherwise designated by Equinix, Equinix's office or agency in New York
will be the office of the trustee maintained for such purpose. The notes will
be issued in denominations of $1,000 and integral multiples of $1,000. The
trustee initially will be paying agent and registrar under the indenture. We
may also act as paying agent or registrar under the indenture.

Escrow Account; Disbursement of Funds

   The notes will be collateralized, pending disbursement, under an escrow
agreement dated as of December 1, 1999, among Equinix, the trustee and State
Street Bank and Trust Company of California, N.A., as escrow agent, by a pledge
of the escrow account referred to in the escrow agreement. The escrow account

                                       60
<PAGE>

will initially contain approximately $37.0 million of the net proceeds from the
sale of the notes. These funds, together with the proceeds from their
investment, will be sufficient to pay interest on the notes for three scheduled
interest payments. The funds will not be sufficient to pay any liquidated
damages described under "The Exchange Offer; Liquidated Damages."

   The escrow agreement provides for the grant by Equinix to the trustee, for
the benefit of the holders, of a first priority security interest in the escrow
collateral. All such security interests will collateralize the payment and
performance when due of all our obligations under the indenture and the notes,
as provided in the escrow agreement. The Liens created by the escrow agreement
will be first priority security interests in the Escrow Collateral. The ability
of holders to realize upon any such funds or securities may be subject to
certain bankruptcy law limitations if there is a bankruptcy of Equinix.

   Under the escrow agreement, funds may be disbursed from the escrow account
only to pay interest on the notes. If a portion of the notes has been retired
by Equinix, funds representing the lesser of:

  .  the excess of the amount sufficient to pay interest through and
     including June 1, 2001 on the notes not so retired; and

  .  the interest payments which have not previously been made on such
     retired notes for each interest payment date through and including the
     interest payment date to occur on June 1, 2001;

shall be paid to Equinix if no default then exists under the indenture.

   Pending such disbursements, all funds contained in the escrow account will
be invested in U.S. Government Securities. Interest earned on the U.S.
Government Securities will be placed in the escrow account. Upon the
acceleration of the maturity of the notes, the escrow agreement will provide
for the foreclosure by the trustee upon the net proceeds of the escrow account.
Under the terms of the indenture, the proceeds of the escrow account shall be
applied, first, to amounts owing to the trustee in respect of fees and expenses
of the trustee and, second, to all obligations under the notes and the
indenture. Under the escrow agreement, assuming that we make the first three
scheduled interest payments on the notes in a timely manner with funds or U.S.
Government Securities held in the escrow account, any remaining U.S. Government
Securities will be released from the escrow account.

Optional Redemption

   Except as set forth below, the notes will not be redeemable at our option
before December 1, 2003. On or after December 1, 2003, the notes will be
subject to redemption at any time at our option, in whole or in part, upon not
less than 30 nor more than 60 days' notice. The notes may be redeemed at the
redemption prices, expressed as percentages of principal amount, below, plus
accrued and unpaid interest to the applicable redemption date. This right is
subject to the right of holders as of the relevant record date to receive
interest due on the relevant interest payment date, if redeemed during the
twelve-month period beginning on December 1 of the years indicated below.

Selection and Notice

   If less than all of the notes are to be redeemed at any time, selection of
notes for redemption will be made by the trustee in compliance with the
requirements of the principal national securities exchange, if any, on which
the notes are then listed, or, if the notes are not so then listed, on a pro
rata basis, by lot or by such

                                       61
<PAGE>

method as we shall deem fair and appropriate. No notes of $1,000 or less shall
be redeemed in part. Notices of redemption shall be mailed by first class mail
at least 30 but not more than 60 days before the redemption date to each holder
of notes to be redeemed at its registered address. Notices of redemption may
not be conditional. If any note is to be redeemed in part only, the notice of
redemption that relates to such note shall state the portion of the principal
amount of the note to be redeemed. A new note in principal amount equal to its
unredeemed portion will be issued in the name of its holder upon cancellation
of the original note. Notes called for redemption will become due on the date
fixed for redemption. On and after the redemption date, interest will cease to
accrue on notes or portions of notes called for redemption unless we default in
their payment.

Mandatory Redemption

   Except as provided under "--Repurchase at the Option of Holders," we will
not be required to make mandatory redemption or sinking fund payments relating
to the notes.

Repurchase at the Option of Holders

 Change of Control

   Upon the occurrence of a Change of Control, each holder will have the right
to require us to purchase all or any part, equal to $1,000 or an integral
multiple of $1,000, of such holder's notes in the offer described below at a
purchase price in cash equal to 101% of the aggregate principal amount of the
note, plus accrued and unpaid interest and liquidated damages, if any, to the
date of purchase. This right is subject to the right of holders as of a record
date to receive interest due on the relevant interest payment date. However, we
shall not be obligated to repurchase notes in a Change of Control offer in the
event that we have exercised our rights to redeem all of the notes under the
indenture. Within 30 days following any Change of Control, we will mail a
notice to each holder describing the transaction or transactions that
constitute the Change of Control and offering to purchase notes on the date
specified in such notice, which date shall be no earlier than 30 and no later
than 60 days from the date such notice is mailed, in accordance with the
procedures required by the indenture and described in such notice.

   We will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations to the extent such laws and
regulations are applicable in connection with the purchase of notes as a result
of a Change of Control. To the extent that the provisions of any securities
laws or regulations conflict with any of the provisions of this covenant, we
will comply with the applicable securities laws and regulations and will be
deemed not to have breached our obligations under this covenant by virtue of
such compliance.

   On the Change of Control payment date, we will, to the extent lawful:

  . accept for payment all notes or portions of notes properly tendered in
    the Change of Control offer;

  . deposit with the paying agent an amount equal to the Change of Control
    payment plus accrued and unpaid interest and liquidated damages, if any,
    in respect of all notes or portions of notes so tendered; and

  . deliver or cause to be delivered to the trustee notes so accepted
    together with an Officers' Certificate stating the aggregate principal
    amount of notes or portions of notes being purchased by us.

The paying agent will promptly mail or deliver to each holder of notes so
tendered the Change of Control payment plus accrued and unpaid interest and
liquidated damages, if any, for such notes, and the trustee will promptly
authenticate and mail or deliver, or cause to be transferred by book entry, to
each holder a new note equal in principal amount to any unpurchased portion of
notes surrendered, if any. Each such new note will be in a principal amount of
$1,000 or an integral multiple of $1,000. We will publicly announce the results
of the Change of Control offer on or as soon as practicable after the Change of
Control payment date.

   The Change of Control provisions described above will be applicable whether
or not any other provisions of the indenture are applicable. Except as
described above relating to a Change of Control, the indenture will not contain
provisions that permit the holders to require that we purchase or redeem the
notes if there is a takeover, recapitalization or similar transaction. Our
ability to purchase notes upon a Change of Control may be limited by our then
existing financial resources. There can be no assurance that sufficient funds
will be available when necessary to make any such required purchases. We shall
not be required to make a Change of Control offer if a third party makes the
Change of Control offer in the manner, at the times and otherwise in compliance
with the requirements of the indenture and purchases all notes validly tendered
and not withdrawn. See "Risk Factors--We may not have sufficient funds to
purchase the exchange notes as required upon a change of control."

 Asset Sales

   We will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly, consummate any Asset Sale, unless:

  .  we, or such Restricted Subsidiary, as the case may be, receive
     consideration at the time of such Asset Sale at least equal to the fair
     market value, as determined in good faith by our board of directors and
     set forth in an Officer's Certificate delivered to the trustee, of the
     assets or Equity Interests issued or sold or otherwise disposed of;

  .  at least 75% of the consideration is in the form of cash and/or Cash
     Equivalents or Qualified Consideration; and

  .  the Net Cash Proceeds received by Equinix, or such Restricted
     Subsidiary, as the case may be, from such Asset Sale are applied within
     360 days following the receipt of such Net Cash Proceeds, to the extent
     Equinix, or such Restricted Subsidiary, as the case may be, elects:

    (a) to the redemption or repurchase of outstanding Indebtedness, (1)
        that is either (A) secured Indebtedness or (B) Indebtedness of
        Equinix that ranks equally with the notes but has an earlier
        maturity date, in either case other than Subordinated Indebtedness,
        or (2) that is Indebtedness of a Restricted Subsidiary; and/or

    (b) to reinvest such Net Cash Proceeds, or any portion, in properties
        or assets, including Equity Interests of a person that will become
        a Restricted Subsidiary as a result of such investment, that will
        be used in a Permitted Business.

The balance of such Net Cash Proceeds, after the application of such Net Cash
Proceeds as described in the immediately preceding clauses (a) and (b), shall
constitute Excess Proceeds.

   When the aggregate amount of Excess Proceeds equals or exceeds $10 million,
taking into account income earned on such Excess Proceeds, we will be required
to make a pro rata offer to all holders of notes and equally-ranking
Indebtedness with comparable provisions requiring such Indebtedness to be
purchased with the proceeds of such Asset Sale, called an Asset Sale Offer. We
must offer to purchase the maximum principal amount, or accreted value in the
case of Indebtedness issued with an original issue discount, of notes and
equally-ranking Indebtedness that may be purchased out of the Excess Proceeds,
at a purchase price in cash in an amount equal to 100% of the principal amount
or the accreted value of the note, as applicable, plus accrued and unpaid
interest thereon to the date of purchase, subject to the right of holders as of
the relevant record date to receive interest due on the relevant interest
payment date, in accordance with the procedures set forth in the indenture and
the agreements governing such equally-ranking Indebtedness. To the extent that
any Excess Proceeds remain after consummation of an Asset Sale Offer, Equinix
may use such Excess Proceeds for any purpose not otherwise prohibited by the
indenture. If the aggregate principal amount of notes and equally-ranking
Indebtedness tendered in such Asset Sale Offer surrendered by their holders
exceeds the amount of Excess Proceeds, the trustee shall select the notes and
equally-ranking Indebtedness to be purchased on a pro rata basis in proportion
to the respective principal amounts, or accreted values in the case of
Indebtedness

                                       63
<PAGE>

issued with an original issue discount, of the notes and such other
Indebtedness. On completion of such Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero for purposes of the first sentence of this
paragraph.

   The amount of:

  .  any liabilities, as shown on Equinix's or such Restricted Subsidiary's,
     as the case may be, most recent balance sheet, other than Subordinated
     Indebtedness, of Equinix or any Restricted Subsidiary, that are assumed
     by the transferee of any such assets under an agreement that immediately
     releases Equinix and all of the Restricted Subsidiaries from all
     liability in respect of such liabilities;

  .  Indebtedness of any Restricted Subsidiary that is no longer a Restricted
     Subsidiary as a result of such Asset Sale, if Equinix and all of the
     Restricted Subsidiaries are immediately released from all Guarantees of
     payment of such Indebtedness and such Indebtedness is no longer the
     liability of Equinix or any of the Restricted Subsidiaries; and

  .  any securities, notes or other obligations received by Equinix, or such
     Restricted Subsidiary, as the case may be, from such transferee that are
     converted by Equinix, or such Restricted Subsidiary, as the case may be,
     into cash and/or Cash Equivalents within 90 days of the date of such
     Asset Sale, to the extent of the cash and/or Cash Equivalents received;

will be deemed to be cash and/or Cash Equivalents for purposes of this
provision.

   Notwithstanding any provision of this covenant, its provisions will not
apply to any transaction constituting a Restricted Payment that is permitted by
the Restricted Payments covenant or that otherwise constitutes a Permitted
Investment.

Certain Covenants

 Restricted Payments

   We will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly make any of the following Restricted Payments:

  .  declare or pay any dividend or make any other payment or distribution on
     account of Equinix's Equity Interests or to the direct or indirect
     holders of Equinix's Equity Interests in their capacity as stockholders,
     other than dividends or distributions payable in Equity Interests, other
     than Disqualified Stock of Equinix or to Equinix or a Restricted
     Subsidiary of Equinix;

  .  purchase, redeem or otherwise acquire or retire for value any Equity
     Interests of Equinix or any direct or indirect parent of Equinix, other
     than any such Equity Interests owned by Equinix or any Restricted
     Subsidiary of Equinix;

  .  make any payment on or relating to, or purchase, redeem, defease or
     otherwise acquire or retire for value any Subordinated Indebtedness,
     except a payment of interest or principal at any Stated Maturity; or

  .  make any Restricted Investment;

unless:

  .  at the time of and after giving effect to such Restricted Payment, no
     default or Event of Default shall have occurred and be continuing;

  .  Equinix would, at the time of such Restricted Payment and after giving
     pro forma effect thereto as if such Restricted Payment had been made at
     the beginning of the applicable period, have been permitted to incur at
     least $1.00 of additional Indebtedness as described below under
     "Incurrence of Indebtedness and Issuance of Preferred Stock"; and

                                       64
<PAGE>

  .  such Restricted Payment, together with the aggregate amount of all other
     Restricted Payments made by Equinix and the Restricted Subsidiaries on
     or after the Issue Date, is less than the sum, without duplication, of

    (a) the amount of Equinix's (1) Cumulative Consolidated Cash Flow
        determined at the time of such Restricted Payment less (2) 150% of
        the cumulative consolidated interest expense, determined for the
        period commencing on the first day of the fiscal quarter which
        includes the Issue Date and ending on the last day of the last
        fiscal quarter preceding the date on which such Restricted Payment
        is to be made for which reports have been filed with the Commission
        or provided to the trustee according to the "Reports" covenant;
        plus

    (b) 100% of the aggregate Net Cash Proceeds received by Equinix after
        the Issue Date as a Capital Contribution or from the issue or sale,
        other than to a Subsidiary of Equinix, of Equity Interests of
        Equinix, other than Disqualified Stock, or from the issue or sale,
        other than to a Subsidiary of Equinix, of Disqualified Stock or
        debt securities of Equinix that have been converted or exchanged
        into such Equity Interests, plus the amount of Net Cash Proceeds
        received by Equinix upon such conversion or exchange, other than a
        conversion or exchange by a Subsidiary of Equinix; plus

    (c) the aggregate amount equal to the net reduction in Restricted
        Investments in Unrestricted Subsidiaries on or after the Issue Date
        resulting from (1) dividends, distributions, interest payments,
        return of capital, repayments of Restricted Investments or other
        transfers of assets to Equinix or any Restricted Subsidiary from
        any Unrestricted Subsidiary and not otherwise included in the
        calculation of Cumulative Consolidated Cash Flow required by
        (a) above, (2) proceeds realized by Equinix or any Restricted
        Subsidiary upon the sale of such Restricted Investment to a person
        other than Equinix or any Subsidiary of Equinix, or (3) the
        redesignation of any Unrestricted Subsidiary as a Restricted
        Subsidiary, not to exceed in the case of any of the immediately
        preceding clauses (1), (2) or (3) the aggregate amount of
        Restricted Investments made by Equinix or any Restricted Subsidiary
        in such Unrestricted Subsidiary on or after the Issue Date; plus

    (d) to the extent that any Restricted Investment that was made on or
        after the Issue Date is sold for cash or otherwise liquidated or
        repaid for cash, the lesser of, to the extent paid to Equinix or a
        Restricted Subsidiary, (1) the cash return of capital relating to
        such Restricted Investment, less any cost of disposition and (2)
        the initial amount of such Restricted Investment; minus

    (e) 50% of the cumulative aggregate principal amount of any outstanding
        Indebtedness incurred according to the second clause of the first
        paragraph of the covenant described below under "Incurrence of
        Indebtedness and Issuance of Preferred Stock."

   So long as no default or Event of Default shall have occurred and be
continuing, the foregoing provisions will not prohibit:

  .  the payment of any dividend within 60 days after the date it is
     declared, if at the time it is declared such payment would have complied
     with the foregoing provisions;

  .  the redemption, repurchase, retirement, defeasance or other acquisition
     of any Subordinated Indebtedness or Equity Interests of Equinix in
     exchange for, or out of the Net Cash Proceeds of the substantially
     concurrent sale, other than to a Subsidiary of Equinix, of, Equity
     Interests of Equinix, other than any Disqualified Stock; provided that
     the amount of any such Net Cash Proceeds that are utilized for, and the
     Equity Interests issued or exchanged for, any such redemption,
     repurchase, retirement, defeasance or other acquisition shall be
     excluded from the third clause of the preceding paragraph and each other
     clause of this paragraph;

  .  the defeasance, redemption, retirement, repurchase or other acquisition
     of Subordinated Indebtedness with the Net Cash Proceeds from, or issued
     in exchange for, a substantially concurrent incurrence of

                                       65
<PAGE>

     Permitted Refinancing Indebtedness; provided that the amount of any such
     Net Cash Proceeds that are utilized for any such redemption, repurchase,
     retirement, defeasance or other acquisition shall be excluded from the
     third clause of the preceding paragraph and each other clause of this
     paragraph;

  .  the repurchase, redemption or other acquisition or retirement for value
     of any Equity Interests of Equinix held by any member of Equinix's or a
     Restricted Subsidiary's management; provided that the aggregate price
     paid for all such repurchased, redeemed, acquired or retired Equity
     Interests shall not exceed $3 million in any fiscal year;

  .  Restricted Investments not to exceed the aggregate fair market value,
     measured on the date each such Restricted Investment was made or
     returned, as applicable, when taken together with all other Restricted
     Investments made according to this clause that are at the time
     outstanding, the sum of (a) $30 million, plus (b) the amount then
     available for the making of Restricted Payments according to the third
     clause of the preceding paragraph without giving effect to its subclause
     (a);

  .  Restricted Investments the payment for which consists exclusively of
     Equity Interests, other than Disqualified Stock, of Equinix; and

  .  the repurchase of Equity Interests of Equinix in accordance with, and
     only to the extent required by, dissenters' rights of appraisal under
     applicable law.

Each Restricted Payment permitted by the first, fourth, fifth, sixth and
seventh clauses above shall be included, and each Restricted Payment permitted
by the second, third and sixth clauses above shall be excluded, except as
specifically set forth in each such clause, for all purposes when performing
the calculation set forth in the last bullet point of the preceding paragraph
of this covenant.

   Our board of directors may not designate any Subsidiary of Equinix as an
Unrestricted Subsidiary, unless:

  .  no default or Event of Default shall have occurred and be continuing at
     the time of or after giving effect to such designation; and

  .  Equinix would not be prohibited under the indenture from making a
     Restricted Investment at the time of such designation, assuming the
     effectiveness of such designation for purposes of this covenant, in an
     amount equal to the fair market value of the net Investment of Equinix
     and all Restricted Subsidiaries in such Subsidiary on such date.

This prohibition shall not apply to a newly created Subsidiary in which no
investment, apart from any de minimis amount required to capitalize the
Subsidiary in connection with its organization, has previously been made.

   If there is any such designation, all outstanding Investments owned by
Equinix and the Restricted Subsidiaries in the Subsidiary so designated will
be deemed to be a Restricted Investment made as of the time of such
designation and will reduce the amount available for Restricted Payments under
the first or second paragraph of this covenant. All such outstanding
Investments will be deemed to constitute Restricted Payments in an amount
equal to the fair market value of such Investments at the time of such
designation.

   The indenture also provides that a designation may be revoked and an
Unrestricted Subsidiary may thus be redesignated as a Restricted Subsidiary by
a resolution of our board of directors delivered to the trustee. However,
Equinix will not make any revocation unless:

  .  no default or Event of Default shall have occurred and be continuing at
     the time of, or after giving effect to, such revocation; and

  .  all Liens and Indebtedness of such Unrestricted Subsidiary outstanding
     immediately following such revocation would, if incurred at such time,
     have been permitted to be incurred at such time for all purposes under
     the indenture.


                                      66
<PAGE>

   The amount of all Restricted Payments, other than cash, shall be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by Equinix, or such Restricted
Subsidiary, as the case may be, under the Restricted Payment. The fair market
value of any asset(s) or securities that are required to be valued by this
covenant shall be determined in good faith by our board of directors. Their
determination shall be supported by the opinion or appraisal of an accounting,
appraisal or investment banking firm of national standing if such fair market
value would exceed $10 million.

 Incurrence of Indebtedness and Issuance of Preferred Stock

   We will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable for, contingently or otherwise, including
by way of merger, consolidation or acquisition, any Indebtedness and we will
not issue or incur any Disqualified Stock and will not permit any of the
Restricted Subsidiaries to issue or incur any shares of Preferred Stock.
However, we may incur Indebtedness or issue or incur shares of Disqualified
Stock and the Restricted Subsidiaries may incur Acquired Debt or Acquired
Preferred Stock if either:

  .  the Consolidated Leverage Ratio at the end of Equinix's most recently
     ended fiscal quarter, for which a consolidated balance sheet of Equinix
     which has been filed with the Commission or provided to the trustee,
     immediately preceding the date on which such additional Indebtedness is
     incurred or such Preferred Stock is issued or incurred would have been
     less than 6.0 to 1.0, determined on a pro forma basis, including a pro
     forma application of the net proceeds therefrom; or

  .  the Consolidated Capital Ratio at the end of the most recently ended
     fiscal quarter, for which a consolidated balance sheet of Equinix has
     been filed with the Commission or provided to the trustee, would have
     been less than 2.0 to 1.0 determined on a pro forma basis, including a
     pro forma application of the net proceeds therefrom.

   Notwithstanding the foregoing, the provisions of the paragraph set forth
immediately above will not prohibit the incurrence of any of the following
items of Indebtedness (collectively, "Permitted Indebtedness"):

  .  Permitted Refinancing Indebtedness;

  .  the incurrence by Equinix of Indebtedness represented by the notes;

  .  the incurrence of Indebtedness by Equinix owing to any Restricted
     Subsidiary or Indebtedness of any Restricted Subsidiary owing to Equinix
     or any other Restricted Subsidiary, such Indebtedness deemed to be
     incurred upon such Indebtedness being held by any person other than
     Equinix or such Restricted Subsidiary including upon designation and
     upon such Restricted Subsidiary otherwise no longer being a Restricted
     Subsidiary; provided that in the case of Indebtedness of Equinix, such
     obligations shall be unsecured and subordinated in all respects to
     Equinix's obligations in accordance with the notes;

  .  the incurrence by Equinix of Indebtedness in an aggregate amount
     incurred and outstanding at any time under this clause of up to $30
     million;

  .  the incurrence (a) by Equinix or any Restricted Subsidiary, other than
     any Foreign Subsidiary, of Senior Debt, including under one or more
     Permitted Credit Facilities, and (b) by any Foreign Subsidiary of
     Indebtedness under one or more Permitted Foreign Credit Facilities, in
     an aggregate amount incurred and outstanding at any time under this
     clause of up to the sum of (a) $125 million and (b) 85% of the aggregate
     accounts receivable of Equinix and the Restricted Subsidiaries as of the
     date of the most recently available balance sheet of Equinix which has
     been included in a report filed with the Commission or provided to the
     trustee;

  .  the incurrence by Equinix or any Foreign Subsidiary of Purchase Money
     Indebtedness (a) under the terms of any Purchase Money Indebtedness
     facility existing and as in effect on the Issue Date or (b) constituting
     not more than 75% of the cost, including shipping, installation and
     importation costs and

                                       67
<PAGE>

     sales, use and similar taxes, collectively "Costs", payable upon
     acquisition of the subject property, determined in accordance with GAAP
     in good faith by our board of directors, to Equinix or any such Foreign
     Subsidiary, as applicable, of the property so purchased, developed,
     acquired, constructed, improved or leased; provided, that relating to
     any Purchase Money Indebtedness incurred under clause (b) above, at
     least 25% of the Costs payable upon acquisition of the subject property
     shall be funded from Newly Raised Capital; provided, further, that any
     assets acquired by a Foreign Subsidiary under this clause are acquired
     for use in the ordinary course of business of such Foreign Subsidiary;

  .  the incurrence by Equinix or any of the Restricted Subsidiaries of
     Hedging Obligations that are incurred for the purpose of fixing or
     hedging interest or foreign currency exchange rate risk relating to any
     floating rate Indebtedness or foreign currency based Indebtedness,
     respectively, that is permitted by the terms of the indenture to be
     outstanding; provided that the notional amount of any such Hedging
     Obligation does not exceed the amount of Indebtedness or other liability
     to which such Hedging Obligation relates; and

  .  the incurrence by Equinix and the Restricted Subsidiaries of
     Indebtedness solely in respect of bankers acceptances, letters of credit
     and performance bonds, all in the ordinary course of business.

   Indebtedness or Preferred Stock of any person which is outstanding at the
time such person becomes a Restricted Subsidiary of Equinix, including upon
designation of any Subsidiary or other person as a Restricted Subsidiary or
upon a Revocation such that such Subsidiary becomes a Restricted Subsidiary, or
is merged with or into or consolidated with Equinix or a Restricted Subsidiary
of Equinix, shall be deemed to have been incurred at the time such person
becomes such a Restricted Subsidiary of Equinix or is merged with or into or
consolidated with Equinix or a Restricted Subsidiary of Equinix, as applicable.

   Upon each incurrence, Equinix may designate under which provision of this
covenant such Indebtedness is being incurred. Such Indebtedness shall not be
deemed to have been incurred by Equinix under any other provision of this
covenant, except as stated otherwise in the foregoing provisions or in the next
sentence. For purposes of determining compliance with this covenant, in the
event that an item of Indebtedness meets the criteria of more than one of the
types of Indebtedness described in the clauses above, or is permitted under the
first paragraph of this covenant and under one or more of such clauses,
Equinix, in our sole discretion, may from time to time reclassify such item of
Indebtedness.

   Equinix will not, and will not permit any of the Restricted Subsidiaries,
other than Foreign Subsidiaries, to, incur any Indebtedness, including
Permitted Indebtedness, that is contractually subordinated in right of payment
to any other Indebtedness unless such Indebtedness is also contractually
subordinated in right of payment to the notes on substantially identical terms.
However, no Indebtedness shall be deemed to be contractually subordinated in
right of payment to any other Indebtedness solely by virtue of being unsecured.

 Liens

   We will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly, create, incur, assume or otherwise cause or suffer to
exist or become effective any Lien of any kind, other than Permitted Liens, to
secure Indebtedness upon any of our property or assets or upon any income or
profits therefrom unless all payments due under the indenture and the notes are
secured, except as provided in the next clause, on an equal and ratable basis
with the obligations so secured. No Lien shall be granted or be allowed to
exist which secures Subordinated Indebtedness except relating to Acquired Debt,
in which case, however, such Liens must be made junior and subordinate to the
Liens granted to the holders.

                                       68

 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

   We will not, and will not permit any of the Restricted Subsidiaries to,
directly or indirectly, create or otherwise cause or suffer to exist or become
effective any encumbrance or restriction on the ability of any Restricted
Subsidiary to:

  .  (a) pay dividends or make any other distributions to Equinix or any of
     the Restricted Subsidiaries on its Capital Stock or relating to any
     other interest or participation in, or measured by, its profits, or
     (b) pay any Indebtedness owed to Equinix or any of the Restricted
     Subsidiaries;

  .  make loans or advances to Equinix or any of the Restricted Subsidiaries;
     or

  .  transfer any of its properties or assets to Equinix or any of the
     Restricted Subsidiaries.

   The foregoing restrictions will not apply to encumbrances or restrictions
existing under or by reason of:

  .  Existing Indebtedness as in effect on the Issue Date;

  .  any Permitted Credit Facility or Permitted Foreign Credit Facility,
     provided that (a) the aggregate outstanding amount of any such
     Indebtedness does not exceed the amount permitted under the fifth clause
     of the definition of Permitted Indebtedness, (b) relating to any
     Permitted Credit Facility, such restrictions apply only if there is a
     payment default under such Permitted Credit Facility, and (c) the chief
     financial officer of Equinix determines in good faith that any such
     restrictions contained in any such Permitted Credit Facility or
     Permitted Foreign Credit Facilities are no more restrictive, taken as a
     whole, than those contained in a similar credit facility with terms that
     are commercially reasonable for a borrower engaged in a business
     comparable to Equinix that has substantially comparable Indebtedness and
     that any such restrictions will not materially affect Equinix's ability
     to make principal, premium or interest payments on the notes;

  .  applicable law;

  .  any instrument governing Indebtedness or Capital Stock of a Person or
     assets acquired by Equinix or any of the Restricted Subsidiaries as in
     effect at the time of such acquisition, except to the extent such
     Indebtedness was incurred in connection with or in contemplation of such
     acquisition, which encumbrance or restriction is not applicable to any
     person, or the properties or assets of any person, other than the
     person, or the property or assets of the person, so acquired; provided,
     that in the case of Indebtedness, such Indebtedness was permitted by the
     terms of the indenture to be incurred;

  .  customary non-assignment provisions in leases entered into in the
     ordinary course of business;

  .  purchase money obligations for property acquired in the ordinary course
     of business that impose restrictions on transfer on the property so
     acquired, constructed, leased or improved;

  .  any agreement for the sale or other disposition of a Restricted
     Subsidiary that restricts distributions by that Restricted Subsidiary
     pending its sale or other disposition, provided that the consummation of
     such transaction would not result in an Event of Default or an event
     that, with the passing of time or giving of notice or both, would
     constitute an Event of Default, that such restriction terminates if such
     transaction is not consummated and that the consummation or abandonment
     of such transaction occurs within one year of the date such agreement
     was entered into;

  .  Permitted Refinancing Indebtedness, provided that the restrictions
     contained in the agreements governing such Permitted Refinancing
     Indebtedness are no more restrictive, taken as a whole, than those
     contained in the agreements governing the Indebtedness being extended,
     refinanced, renewed, replaced, defeased or refunded;

  .  Liens securing Indebtedness otherwise permitted to be incurred under the
     provisions of the covenant governing Liens that limit the right of
     Equinix or any of the Restricted Subsidiaries to dispose of the assets
     subject to such Lien; and


                                      69
<PAGE>

  .  provisions relating to the disposition or distribution of assets or
     property in joint venture agreements and other similar agreements
     entered into in the ordinary course of business.

 Merger, Consolidation, or Sale of Assets

   We may not, directly or indirectly, consolidate or merge with or into,
whether or not we are the surviving corporation, or sell, assign, transfer,
convey or otherwise dispose of all or substantially all of our properties or
assets, in one or more related transactions, to another person, or permit any
of the Restricted Subsidiaries to enter into any such transaction or series of
transactions, if it would result in such disposition of all or substantially
all of the assets of Equinix and the Restricted Subsidiaries on a consolidated
basis, unless:

  .  Equinix is the surviving corporation or the person formed by or
     surviving any such consolidation or merger, if other than Equinix, or to
     which such sale, assignment, transfer, conveyance or other disposition
     shall have been made is a corporation organized or existing under the
     laws of the United States, any state or the District of Columbia;

  .  the person formed by or surviving any such consolidation or merger, if
     other than Equinix, or the person to which such sale, assignment,
     transfer, conveyance or other disposition shall have been made assumes
     all the obligations of Equinix under the registration agreement, the
     notes, the exchange notes and the indenture under a supplemental
     indenture in a form reasonably satisfactory to the trustee;

  .  no default or Event of Default, or an event that, with the passing of
     time or giving of notice or both, would constitute an Event of Default,
     shall exist or shall occur immediately after giving effect on a pro
     forma basis to such transaction;

  .  except in the case of a merger of Equinix with or into a Wholly Owned
     Restricted Subsidiary of Equinix, Equinix or the person formed by or
     surviving any such consolidation or merger, if other than Equinix, or to
     which such sale, assignment, transfer, conveyance or other disposition
     shall have been made will immediately after such transaction and after
     giving pro forma effect thereto and any related financing transactions
     as if the same had occurred at the beginning of the applicable period,
     be permitted to incur at least $1.00 of additional Indebtedness
     according to the first paragraph of the "Incurrence of Indebtedness and
     Issuance of Preferred Stock" covenant;

  .  if, as a result of any such transaction, property or assets of Equinix
     would become subject to a Lien subject to the provisions of the
     indenture described under the "Liens" covenant, Equinix or the successor
     entity to Equinix shall have secured the notes as required by the
     covenant; and

  .  Equinix shall have delivered to the trustee an Officers' Certificate and
     an opinion of counsel, each stating that such consolidation, merger or
     transfer and any supplemental indenture comply with the indenture.

   The indenture also provides that Equinix may not, directly or indirectly,
lease all or substantially all of its properties or assets, in one or more
related transactions, to any other person.

   Upon any consolidation or merger or any transfer of all or substantially all
of the assets of Equinix in accordance with the foregoing, the successor
corporation formed by such consolidation or into which Equinix is merged or to
which such transfer is made shall succeed to and be substituted for, and may
exercise every right and power of, Equinix under the indenture. The effect will
be as if the successor corporation had been named therein as Equinix, and
Equinix shall be released from the obligations under the notes and the
indenture except relating to any obligations that arise from, or are related
to, such transaction. The foregoing shall not apply in the case of a lease.

 Transactions with Affiliates

   We will not, and will not permit any of the Restricted Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any of our
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate, each an
Affiliate transaction, unless:

  .  such Affiliate Transaction is on terms that are not materially less
     favorable to Equinix or the relevant Restricted Subsidiary than those
     that would have been obtained in a comparable transaction by Equinix or
     such Restricted Subsidiary with an unrelated person; and

  .  relating to any Affiliate Transaction or series of related Affiliate
     Transactions:

    (a) involving aggregate consideration in excess of $5 million, Equinix
        delivers to the trustee a resolution of the board of directors set
        forth in an Officers' Certificate that such Affiliate Transaction
        is approved by a majority of the disinterested members of the board
        of directors and that such Affiliate Transaction complies with the
        first clause above and is in the best interests of Equinix or such
        Restricted Subsidiary; and

    (b) if involving aggregate consideration in excess of $10 million, a
        favorable written opinion as to the fairness to Equinix of such
        Affiliate Transaction from a financial point of view is also
        obtained by Equinix from an accounting, appraisal or investment
        banking firm of national standing.

Notwithstanding the foregoing, the following items shall not be deemed to be
Affiliate Transactions:

  .  (a) the entering into, maintaining or performance of any employment
     contract, collective bargaining agreement, benefit plan, program or
     arrangement, related trust agreement or any other similar arrangement
     for or with any employee, officer or director heretofore or hereafter
     entered into in the ordinary course of business, including vacation,
     health, insurance, deferred compensation, retirement, savings or other
     similar plans or (b) the payment of compensation, performance of
     indemnification or contribution obligations, or an issuance, grant or
     award of stock, options, or other equity-related interests or other
     securities, to employees, officers or directors in the ordinary course
     of business;

  .  transactions between or among Equinix and/or the Restricted
     Subsidiaries;

  .  payment of reasonable directors fees;

  .  any sale or other issuance of Equity Interests, other than Disqualified
     Stock, of Equinix;

  .  Affiliate Transactions in effect or approved by the board of directors
     on the Issue Date, including any amendments thereto, provided that the
     terms of such amendments are not materially less favorable to Equinix
     than the terms of such agreement before such amendment; and

  .  Restricted Payments that are permitted under the Restricted Payments
     covenant and Permitted Investments described under clause (d) of its
     definition.

 Business Activities

   We will not, and will not permit any of the Restricted Subsidiaries to,
engage to more than a de minimus extent in any business other than a Permitted
Business.

 Status as Investment Company

   The indenture provides that Equinix will not, and will not permit any of its
Subsidiaries or controlled affiliates to, conduct its business in a fashion
that would cause Equinix to be required to register as an investment company,
as that term is defined in the Investment Company Act of 1940, as amended, or
otherwise to become subject to regulation under the Investment Company Act. For
purposes of establishing Equinix's

                                       71
<PAGE>

compliance with this provision, any exemption which is or would become
available under Section 3(c)(1) or Section 3(c)(7) of the Investment Company
Act will be disregarded.

 Reports

   The indenture provides that at all times from and after the date of the
commencement of an exchange offer or the effectiveness of a shelf registration
statement relating to the notes, a "Registration", whether or not Equinix is
then required to file reports with the Commission, Equinix shall file with the
Commission all such reports and other information as it would be required to
file with the Commission by Sections 13(a) or 15(d) under the Exchange Act if
it were subject thereto. Without cost, Equinix shall supply the applicable
trustee and each applicable holder, or shall supply to the applicable trustee
for forwarding to each such applicable holder, copies of such reports and other
information. At all times before the date of the Registration, Equinix shall,
at its cost, deliver to the trustee and each holder of the notes quarterly and
annual reports substantially equivalent to those which would be required by the
Exchange Act if Equinix were subject thereto. In addition, at all times before
the Registration, upon the request of any holder or any prospective purchaser
of the notes designated by a holder, Equinix shall supply to such holder or
such prospective purchaser the information required under Rule 144A under the
Securities Act.

Events of Default and Remedies

   The indenture provides that each of the following will constitute an Event
of Default:

  .   default for 30 days in the payment when due of interest on the notes;

  .   default in the payment when due of the principal of, or premium, if
      any, on, the notes;

  .   failure by Equinix or any of the Restricted Subsidiaries to comply with
      the provisions described above under the captions "--Change of
      Control," or "--Asset Sales";

  .   failure by Equinix or any of the Restricted Subsidiaries for 60 days
      after notice to comply with any of its other agreements in the
      indenture, the notes or the escrow agreement;

  .   the default under any mortgage, indenture or instrument under which
      there may be issued or by which there may be secured or evidenced any
      Indebtedness of Equinix or any of the Restricted Subsidiaries, or the
      payment of which is Guaranteed by Equinix or any of the Restricted
      Subsidiaries, whether such Indebtedness or Guarantee now exists or is
      created after the Issue Date, and either such Indebtedness is already
      due and payable or such default results in the acceleration of such
      Indebtedness before its express maturity and, in each case, the amount
      of any such Indebtedness, together with the amount of any other such
      Indebtedness the maturity of which has been so accelerated or which is
      already due and payable, aggregates $10 million or more;

  .   one or more judgments, orders or decrees for the payment of money in
      excess of $10 million, individually or in the aggregate, net of
      applicable insurance coverage which is acknowledged in writing by the
      insurer, shall be entered against Equinix or any Restricted Subsidiary
      or any of their respective properties and shall not be discharged and
      there shall have been a period of 60 days or more during which a stay
      of enforcement of such judgment or order, by reason of pending appeal
      or otherwise, shall not be in effect;

  .   Equinix shall assert or acknowledge in writing that the escrow
      agreement is invalid or unenforceable; or

  .   certain events of bankruptcy or insolvency relating to Equinix or any
      of its Significant Subsidiaries.

   If any Event of Default occurs and is continuing, the trustee or the holders
of at least 25% in principal amount of the then outstanding notes may declare
all principal of, premium, if any, on and interest on the notes to be due and
payable immediately. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency relating to
Equinix or a Significant Subsidiary, all outstanding notes will become due and
payable without further action or notice.

                                       72
<PAGE>

   Holders may not directly enforce the indenture or the notes except as
provided in the indenture. Subject to certain limitations, holders of a
majority in principal amount of the then outstanding notes may direct the
trustee in its exercise of any trust or power.

   Holders of a majority in aggregate principal amount of the then outstanding
notes, by notice to the trustee, may, on behalf of all holders, waive any
existing default or Event of Default and its consequences under the indenture,
except a continuing default or Event of Default in the payment of principal of,
premium, if any, or interest on the notes.

   We will be required to deliver to the trustee annually a statement regarding
compliance with the indenture, and we will be required upon becoming aware of
any default or Event of Default to deliver to the trustee a statement
specifying such default or Event of Default. The trustee may withhold from
holders notice of any continuing default or Event of Default, except a default
or Event of Default relating to the payment of principal of, premium, if any,
or interest on, the notes, if it determines that withholding notice is in their
interest.

No Personal Liability of Directors, Officers, Employees, Incorporators or
Shareholders

   No director, officer, employee, incorporator or shareholder of Equinix, as
such, will have any liability for any obligations of Equinix relating to the
notes or the indenture, or for any claim based on, or in respect or by reason
of, such obligations or their creation. Each holder of notes by accepting a
note will waive and release any and all such liability. Such waiver and release
are part of the consideration for issuance of the notes. Such waiver may not be
effective to waive liabilities under federal securities laws and it is the view
of the Commission that such a waiver is against public policy.

Legal Defeasance and Covenant Defeasance

   The indenture provides that Equinix may, at its option and at any time,
elect to have all of its obligations discharged relating to the outstanding
notes, called legal defeasance, except for:

  .  the rights of holders to receive payments in respect of the principal
     of, premium, if any, and interest on such notes when such payments are
     due from the trust referred to below;

  .  Equinix's obligations relating to the notes concerning issuing temporary
     notes, registration of notes, mutilated, destroyed, lost or stolen notes
     and the maintenance of an office or agency for payment and money for
     security payments held in trust;

  .  the rights, powers, trusts, duties and immunities of the trustee, and
     Equinix's obligations in connection therewith; and

  .  the legal defeasance provisions of the indenture.

In addition, Equinix may, at its option and at any time, elect to have its
obligations released relating to certain covenants that are contained in the
indenture, called covenant defeasance, and, thereafter, any omission to comply
with such obligations will not constitute a default or Event of Default. In the
event covenant defeasance occurs, certain events, but not including non-
payment, bankruptcy, receivership, rehabilitation or insolvency events,
described under "--Events of Default and Remedies" will no longer constitute an
Event of Default.

To exercise either legal defeasance or covenant defeasance:

  .  Equinix must irrevocably deposit, or cause to be deposited, with the
     trustee, in trust, for the benefit of the holders, cash in U.S. dollars,
     non-callable Government Securities, or any combination, in such amounts
     as will be sufficient, in the opinion of a nationally recognized firm of
     independent public accountants, to pay the principal of, premium, if
     any, and interest on the outstanding notes on its stated maturity or on
     the applicable redemption date, as the case may be, and Equinix must
     specify whether the notes are being defeased to maturity or to a
     particular redemption date;


                                       73
<PAGE>

  .  in the case of legal defeasance, Equinix must deliver to the trustee an
     opinion of United States counsel reasonably acceptable to the trustee
     confirming that, since the Issue Date, Equinix has received from, or
     there has been published by, the Internal Revenue Service a ruling, or
     there has been a change in the applicable United States federal income
     tax law, in either case to the effect that, and based thereon such
     opinion of counsel shall confirm that, the holders will not recognize
     income, gain or loss for United States federal income tax purposes as a
     result of such legal defeasance, and will be subject to United States
     federal income tax on the same amounts, in the same manner and at the
     same times as would have been the case if such legal defeasance had not
     occurred;

  .  in the case of covenant defeasance, Equinix must deliver to the trustee
     an opinion of counsel in the United States reasonably acceptable to the
     trustee confirming that the holders will not recognize income, gain or
     loss for United States federal income tax purposes as a result of such
     covenant defeasance, and such holders will be subject to United States
     federal income tax on the same amounts, in the same manner and at the
     same times as would have been the case if such covenant defeasance had
     not occurred;

  .  no default or Event of Default shall have occurred and be continuing on
     the date of such deposit, other than a default or Event of Default
     resulting from the borrowing of funds to be applied to such deposit;

  .  such legal defeasance or covenant defeasance will not result in a breach
     or violation of, or constitute a default under, any material agreement
     or instrument, other than the indenture, to which Equinix or any of the
     Restricted Subsidiaries is a party or by which Equinix or any of the
     Restricted Subsidiaries is bound;

  .  Equinix must deliver to the trustee an Officers' Certificate stating
     that the deposit was not made by Equinix with the intent of preferring
     the holders over other creditors of Equinix, or with the intent of
     defeating, hindering, delaying or defrauding creditors of Equinix or
     others; and

  .  Equinix must deliver to the trustee an Officers' Certificate and an
     opinion of United States counsel reasonably acceptable to the trustee,
     each stating that the conditions precedent provided for or relating to
     legal defeasance or covenant defeasance, as applicable, in the case of
     the Officers' Certificate, in the first through sixth clauses and, in
     the case of the opinion of counsel, in the first clause, relating to the
     validity and perfection of the security interest, and the second and
     third clauses of this paragraph, have been complied with.

Satisfaction and Discharge

   The indenture will be discharged and will cease to be of further effect,
except as to surviving rights or registration of transfer or exchange of notes,
as to all outstanding notes when either:

  .  all such notes theretofore authenticated and delivered, except lost,
     stolen or destroyed notes that have been replaced or paid and notes for
     whose payment money has theretofore been deposited in trust or
     segregated and held in trust by Equinix and thereafter repaid to Equinix
     or discharged from such trust, have been delivered to the trustee for
     cancellation; or

  .  (a) all such notes not theretofore delivered to the trustee for
     cancellation have become due and payable and Equinix has irrevocably
     deposited or caused to be deposited with the trustee as trust funds in
     trust for the purpose an amount of money sufficient to pay and discharge
     the entire indebtedness on the notes not theretofore delivered to the
     trustee for cancellation, for principal amount, premium, if any, and
     accrued interest to the date of such deposit; (b) Equinix has paid all
     sums payable by it under the indenture; and (c) Equinix has delivered
     irrevocable instructions to the trustee to apply the deposited money
     toward the payment of the notes at Stated Maturity or on the redemption
     date, as the case may be.


                                       74
<PAGE>

In addition, Equinix must deliver an Officers' Certificate and an opinion of
counsel stating that all conditions precedent to satisfaction and discharge
have been complied with.

Transfer and Exchange

   A holder may transfer or exchange notes in accordance with the procedures
set forth in the indenture. The registrar and the trustee may require a holder,
among other things, to furnish appropriate endorsements and transfer documents,
and Equinix may require a holder to pay any taxes and fees required by law or
permitted by the indenture. Equinix will not be required to transfer or
exchange any note selected for redemption. Also, Equinix will not be required
to transfer or exchange any note for a period of 15 days before:

  .  a selection of notes to be redeemed;

  .  an interest payment date; or

  .  the mailing of notice of a Change of Control Offer or Asset Sale Offer.

The registered holder of a note will be treated as the owner of it for all
purposes under the indenture.

Amendment, Supplement and Waiver

   With the consent of the holders of not less than a majority in aggregate
principal amount of the notes at the time outstanding, Equinix and the trustee
are permitted to amend or supplement the indenture or any supplemental
indenture or modify the rights of the holders. However, that no such
modification may, without the consent of each holder affected thereby:

  .  reduce the principal amount of, change the fixed maturity of, or alter
     the redemption provisions of, the notes;

  .  change the currency in which any notes or amounts owing thereon is
     payable;

  .  reduce the percentage of the aggregate principal amount outstanding of
     notes which must consent to an amendment, supplement or waiver or
     consent to take any action under the indenture or the notes;

  .  impair the right to institute suit for the enforcement of any payment on
     or relating to the notes;

  .  waive a default in payment relating to the notes;

  .  reduce the rate or change the time for payment of interest on the notes;

  .  following the occurrence of a Change of Control or an Asset Sale, alter
     Equinix's obligation to purchase the notes as a result of such Change of
     Control or Asset Sale in accordance with the indenture or waive any
     default in its performance;

  .  affect the ranking of the notes in a manner adverse to the holder of the
     notes; or

  .  release any Liens created by the escrow agreement except in accordance
     with the terms of the escrow agreement.

  Notwithstanding the foregoing, without the consent of any holder of notes,
Equinix and the trustee may amend or supplement the indenture or the notes;

  .  to cure any ambiguity, defect or inconsistency;

  .  to provide for uncertificated notes in addition to or in place of
     certificated notes;

  .  to provide for the assumption of Equinix's obligations to holders in the
     case of a merger or consolidation or sale of all or substantially all of
     Equinix's assets in accordance with the terms of the indenture;

  .  to make any change that would provide any additional rights or benefits
     to the holders or that does not adversely affect the legal rights under
     the indenture of any such holder; or

                                       75
<PAGE>

  .  to comply with the requirements of the Commission to effect or maintain
     the qualification of the indenture under the Trust Indenture Act.

Concerning the Trustee

   The indenture contains certain limitations on the rights of the trustee,
should it become a creditor of Equinix, to obtain payment of claims in certain
cases, or to realize on certain property received in respect of any such claim
as security or otherwise. The trustee will be permitted to engage in other
transactions. However, if it acquires any conflicting interest, it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue, or resign.

   Holders of a majority in principal amount of the then outstanding notes will
have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the trustee, subject to
certain exceptions. In case an Event of Default shall occur which is not cured,
the trustee will be required, in the exercise of its power, to use the degree
of care of a prudent person in the conduct of their own affairs. Subject to
such provisions, the trustee will be under no obligation to exercise any of its
rights or powers under the indenture at the request of any holder, unless such
holder shall have offered to the trustee security and indemnity satisfactory to
it against any loss, liability or expense.

Governing Law

   The indenture and the notes will be governed by and construed in accordance
with the laws of the State of New York.

   Equinix will submit to the jurisdiction of the U.S. federal and New York
state courts located in the Borough of Manhattan, City and State of New York
for purposes of all legal actions and proceedings instituted in connection with
the notes and the indenture.

  .  if such Permitted Refinancing Indebtedness refinances Indebtedness of a
     Restricted Subsidiary, such Permitted Refinancing Indebtedness is
     incurred either by Equinix or by the Restricted Subsidiary who is the
     obligor on the Indebtedness being extended, refinanced, renewed,
     replaced, defeased or refunded; and

                                       86
<PAGE>

  .  such Permitted Refinancing Indebtedness is secured only by the assets,

                         BOOK-ENTRY; DELIVERY AND FORM

   Except as described below, we will initially issue the exchange notes in the
form of one or more registered exchange notes in global form without coupons.
We will deposit each global note on the date of the closing of the exchange
offer with, or one behalf of, DTC in New York, New York, and register the
exchange notes in the name of DTC or its nominee, or will leave such notes in
the custody of the trustee.

Depository Procedures

   The descriptions of the operations and procedures of DTC, Euroclear and
Cedel set forth below are provided solely as a matter of convenience. These
operations and procedures are solely within the control of the respective
settlement systems and are subject to change by them from time to time. Equinix
takes no responsibility for these operations or procedures, and you are urged
to contact the relevant system or its participants directly to discuss these
matters.

   DTC has advised us that it is:

  .  a limited purpose trust company organized under the laws of the State of
     New York;

  .  a "banking organization" within the meaning of the New York Banking Law;

  .  a member of the Federal Reserve System;

  .  a "clearing corporation" within the meaning of the Uniform Commercial
     Code, as amended; and

  .  a "clearing agency" registered under Section 17A of the Exchange Act.

DTC was created to hold securities for its participants and facilitates the
clearance and settlement of securities transactions between participants
through electronic book-entry changes to the accounts of its participants,
thereby eliminating the need for physical transfer and delivery of
certificates. DTC's participants include securities brokers and dealers,
including the initial purchasers, banks and trust companies, clearing
corporations and various other organizations. Indirect access to DTC's system
is also available to other entities such as banks, brokers, dealers and trust
companies, as indirect participants, that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. Investors who
are not participants may beneficially own securities held by or on behalf of
DTC only through participants or indirect participants.

   Equinix expects that under procedures established by DTC:

  .  upon deposit of each global note, DTC will credit the accounts of
     participants designated by the initial purchasers with an interest in
     such global note; and

  .  ownership of the notes will be shown on, and the transfer of their
     ownership will be effected only through, records maintained by DTC,
     relating to the interests of participants, and the records of
     participants and the indirect participants, relating to the interests of
     persons other than participants.

   The laws of some jurisdictions may require that purchasers of securities
take physical delivery of such securities in definitive form. Accordingly, the
ability to transfer interests in the notes represented by a global note to such
persons may be limited. In addition, because DTC can act only on behalf of its
participants, who in turn act on behalf of persons who hold interests through
participants, the ability of a person having an interest in notes represented
by a global note to pledge or transfer such interest to persons or entities
that do not participate in DTC's system, or to otherwise take actions in
respect of such interest, may be affected by the lack of a physical definitive
security in respect of such interest.

   So long as DTC or its nominee is the registered owner of a global note, DTC
or such nominee, as the case may be, will be considered the sole owner or
holder of the notes represented by such global note for all purposes under the
indenture. Except as provided below, owners of beneficial interests in a global
note will not

                                       89
<PAGE>

be entitled to have notes represented by such global note registered in their
names, will not receive or be entitled to receive physical delivery of
certificated notes, and will not be considered as owners or holders under the
indenture for any purpose, including relating to the giving of any direction,
instruction or approval to the trustee thereunder. Accordingly, each holder
owning a beneficial interest in a global note must rely on the procedures of
DTC and, if such holder is not a participant or an indirect participant, on the
procedures of the participant through which such holder owns its interest, to
exercise any rights of a holder of notes under the indenture or such global
note. Equinix understands that under existing industry practice, in the event
that Equinix requests any action of holders of notes, or a holder that is an
owner of a beneficial interest in a global note desires to take any action that
DTC, as the holder of such global note, is entitled to take, DTC would
authorize the participants to take such action and the participants would
authorize holders owning through such participants to take such action or would
otherwise act upon the instruction of such holders. Neither Equinix nor the
trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of notes by DTC, or for maintaining,
supervising or reviewing any records of DTC relating to such notes.

   Payments relating to any notes, including relating to the principal of, and
premium, if any, liquidated damages, if any, and interest on, any notes,
represented by a global note registered in the name of DTC or its nominee on
the applicable record date will be payable by the trustee, as applicable, to or
at the direction of DTC or its nominee in its capacity as the registered holder
of the global note representing such notes under the indenture. Under the terms
of the indenture, Equinix and the trustee may treat the persons in whose names
the notes, including the global notes representing such notes, are registered
as their owners for the purpose of receiving payment on the notes and for any
and all other purposes whatsoever. Accordingly, neither Equinix nor the trustee
has or will have any responsibility or liability for the payment of such
amounts to owners of beneficial interests in a global note (including
principal, premium, if any, liquidated damages, if any, and interest on any
notes). Payments by the participants and the indirect participants to the
owners of beneficial interests in a global note will be governed by standing
instructions and customary industry practice and will be the responsibility of
the participants or the indirect participants and DTC.

   Transfers between participants in DTC will be effected in accordance with
DTC's procedures, and will be settled in same-day funds. Transfers between
participants in Euroclear or Cedel will be effected in the ordinary way in
accordance with their respective rules and operating procedures.

   Subject to compliance with the transfer restrictions applicable to the
notes, cross-market transfers between the participants in DTC, on the one hand,
and Euroclear or Cedel participants, on the other hand, will be effected
through DTC in accordance with DTC's rules on behalf of Euroclear or Cedel, as
the case may be, by its respective depositary; however, such crossmarket
transactions will require delivery of instructions to Euroclear or Cedel, as
the case may be, by the counterparty in such system in accordance with the
rules and procedures and within the established deadlines, Brussels time, of
such system. Euroclear or Cedel, as the case may be, will, if the transaction
meets its settlement requirements, deliver instructions to its respective
depositary to take action to effect final settlement on its behalf by
delivering or receiving interests in the relevant global notes in DTC, and
making or receiving payment in accordance with normal procedures for same-day
funds settlement applicable to DTC. Euroclear participants and Cedel
participants may not deliver instructions directly to the depositories for
Euroclear or Cedel.

   Because of time zone differences, the securities account of a Euroclear or
Cedel participant purchasing an interest in a global note from a participant in
DTC will be credited, and any such crediting will be reported to the relevant
Euroclear or Cedel participant, during the securities settlement processing
day, which must be a business day for Euroclear and Cedel, immediately
following the settlement date of DTC. Cash received in Euroclear or Cedel as a
result of sales of interest in a global note by or through a Euroclear or Cedel
participant to a participant in DTC will be received with value on the
settlement date of DTC but will be available in the relevant Euroclear or Cedel
cash account only as of the business day for Euroclear or Cedel following DTC's
settlement date.

                                       90
<PAGE>

   Although DTC, Euroclear and Cedel have agreed to the foregoing procedures to
facilitate transfers of interests in the global notes among participants in
DTC, Euroclear and Cedel, they are under no obligation to perform or to
continue to perform such procedures, and such procedures may be discontinued at
any time. Neither Equinix nor the trustee will have any responsibility for the
performance by DTC, Euroclear or Cedel or their respective participants or
indirect participants of their respective obligations under the rules and
procedures governing their operations.

   DTC and Year 2000 Problems. DTC's management is aware that some computer
applications, systems, and the like for processing data that are dependent upon
calendar dates, including dates before, on or after January 1, 2000, may
encounter "Year 2000 problems." DTC has informed participants and other members
of the financial community that it has developed and is implementing a program
so that its systems, as the same relate to the timely payment of distributions,
including principal and income payments, to securityholders, book-entry
deliveries, and settlement of trades within DTC, continue to function
appropriately. This program includes a technical assessment and a remediation
plan, each of which is complete. Additionally, DTC's plan includes a testing
phase, which is expected to be completed within appropriate time frames.
However, DTC's ability to perform its services properly is also dependent upon
other parties, including but not limited to Equinix and its agents, as well as
third party vendors from whom DTC licenses software and hardware, and third
party vendors on whom DTC relies for information or the provision of services,
including telecommunication and electrical utility service providers, among
others. DTC has informed the financial community that it is contacting, and
will continue to contact, third party vendors from whom DTC acquires services
to impress upon them the importance of such services being Year 2000 compliant,
and to determine the extent of their efforts for Year 2000 remediation and, as
appropriate, testing of their services. In addition, DTC is in the process of
developing such contingency plans as it deems appropriate.

   According to DTC, the foregoing information relating to DTC has been
provided to the financial community for informational purposes only and is not
intended to serve as a representation, warranty or contract modification of any
kind.

Certificated Notes

   If:

  .  Equinix notifies the trustee in writing that DTC is no longer willing or
     able to act as a depositary or DTC ceases to be registered as a clearing
     agency under the Exchange Act and a successor depositary is not
     appointed within 90 days of such notice or cessation;

  .  Equinix, at its option, notifies the trustee in writing that they elect
     to cause the issuance of the notes in certificated form under the
     indenture; or

  .  upon the occurrence of other events as provided in the indenture;

then, upon surrender by DTC of such global notes, Certificated Securities will
be issued to each person that DTC identifies as the beneficial owner of the
notes represented by such global notes. Upon any such issuance, the trustee is
required to register such certificated securities in the name of such person or
persons, or the nominee of any person or persons, and cause the same to be
delivered to such person or persons.

   Neither the Equinix nor the trustee shall be liable for any delay by DTC or
any participant or indirect participant in identifying the beneficial owners of
the related notes and each such person may conclusively rely on, and shall be
protected in relying on, instructions from DTC for all purposes, including
relating to the registration and delivery, and the respective principal
amounts, of the notes to be issued.

                UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

   The following discussion is a summary of the material United States federal
income tax considerations relevant to the exchange of the initial notes for
exchange notes pursuant to the exchange offer and to the ownership and
disposition of the exchange notes. The discussion is based upon the Internal
Revenue Code of 1986, as amended (the "Code"), U.S. Treasury Regulations,
Internal Revenue Service ("IRS") rulings and pronouncements and judicial
decisions all in effect as of the date hereof, all of which are subject to
change at any time, and any such change may be applied retroactively in a
manner that could adversely affect a holder of the initial notes or the
exchange notes. The discussion does not address all of the U.S. federal income
tax consequences that may be relevant to a holder in light of such holder's
particular circumstances or to holders subject to special tax rules, such as
certain financial institutions, insurance companies, dealers in securities or
currencies, tax-exempt organizations and persons holding the initial notes or
exchange notes as part of a "straddle," "hedge" or "conversion transaction."
Moreover, the effect of any applicable state, local or foreign tax laws is not
discussed. The discussion below assumes that the initial notes and exchange
notes are held as "capital assets" within the meaning of Section 1221 of the
Code. For purposes of this summary, the term "Equinix" refers only to Equinix,
Inc. and not to any of its subsidiaries. Also, in this description the term
"notes" refers to the "initial notes" and "exchange notes" collectively.

   As used herein, "U.S. holder" means a beneficial owner of an exchange note
who or that (i) is a citizen or resident of the United States, (ii) is a
corporation, partnership or other entity created or organized in or under the
laws of the United States, or political subdivision of the United States, (iii)
is an estate the income of which is subject to U.S. federal income taxation
regardless of its source, (iv) is a trust if (A) a U.S. court is able to
exercise primary supervision over the administration of the trust and (B) one
or more U.S. fiduciaries have authority to control all substantial decisions of
the trust, or (v) is otherwise subject to U.S. federal income tax on a net
income basis in respect of the exchange notes. As used herein, a "non-U.S.
holder" means a holder who or that is not a U.S. holder.

   Persons considering exchanging their initial notes for exchange notes should
consult their own tax advisors with regard to the application of the united
states federal income tax considerations discussed below to their particular
situations as well as the application of any state, local, foreign or other tax
laws, including gift and estate tax laws and any applicable tax treaty.

Federal Income Tax Consequences of the Exchange Offer

   The exchange of the initial notes for the exchange notes in accordance with
the exchange offer should not be treated as an exchange for federal income tax
purposes because the exchange notes should not be considered to differ
materially in kind or in extent from the initial notes. Rather, the exchange
notes received by a holder should be treated as a continuation of the initial
notes in the hands of such holder. As a result, there should be no federal
income tax consequences to holders exchanging the initial notes for exchange
notes in accordance with the exchange offer, and the federal income tax
consequences of holding and disposing of the exchange notes should be the same
as the federal income tax consequences of holding and disposing of the initial
notes. Accordingly, the holder must, among other things, continue to include
original issue discount ("OID") in income as if the exchange had not occurred.
See below, "--The Exchange Notes--Original Issue Discount", for a description
of the OID rules applicable to the exchange notes.

U.S. Holders

 The Exchange Notes

   Interest. The stated interest on the exchange notes generally will be
taxable to a U.S. holder as ordinary income at the time that it is paid or
accrued, in accordance with the U.S. holder's method of accounting for

                                       92
<PAGE>

federal income tax purposes. Failure of Equinix to continue to cause the
registration statement of which this prospectus is a part to continue to be
effective or useable in connection with its intended purpose under the
registration rights agreement as described under "The Exchange Offer; Purpose
of the Exchange Offer" may result in the payment of predetermined liquidated
damages in the manner described therein, which payments will be treated as
additional interest on the notes. According to Treasury Regulations, the
possibility of a change in the interest rate will not affect the amount of
interest income recognized by a U.S. holder (or the timing of such recognition)
if the likelihood of the change, as of the date the initial notes were issued,
was remote. Equinix believes that as of the date the initial notes were issued,
the likelihood of a change in the interest rate on such notes was remote and
has not and does not intend to treat the possibility of a change in the
interest rate as affecting the yield to maturity of any initial notes or
exchange notes. There can be no assurance that the IRS will agree with such
position.

   Original Issue Discount. The initial notes were issued as part of an
investment unit comprised of $1,000 principal amount of initial notes and one
warrant to purchase shares of the common stock of Equinix. Equinix and the
initial purchasers of the initial notes (the "Initial Purchasers") allocated in
the purchase agreement for the initial notes a purchase price of $909.96 to
each $1,000 principal amount at maturity of initial notes. This allocation
reflected Equinix's and the Initial Purchasers' judgement as to the relative
values of the initial notes and warrants at the time of issuance but is not
binding on the IRS.

   Equinix's and the Initial Purchaser's allocation of the issue price of the
units will be binding on U.S. holders of exchange notes who acquire such notes
in the exchange offer in exchange for initial notes that were in turn acquired
by such holder directly from Equinix, unless the U.S. holder discloses the use
of a different allocation in a statement attached to its timely federal income
tax return for the year in which the unit was acquired. If a U.S. holder
acquired a unit at a price different from that on which Equinix's and the
Initial Purchaser's allocation is based, such holder may be treated as having
acquired the initial notes for an amount greater or less than the amount
allocated to such notes as set forth above thereby resulting in market discount
or bond premium, as discussed below. U.S. holders considering the use of an
issue price allocation different from that described above should consult their
tax advisors as to the consequences thereof.

   The initial notes will have OID in an amount equal to the excess of the
stated redemption price at maturity over the issue price of such initial notes
(as discussed above) and the exchange notes that are acquired in the exchange
offer will have the same amount of OID. U.S. holders will be required to
include OID in ordinary income over the period that they hold the exchange
notes in advance of the receipt of cash attributable thereto. The amount of OID
to be included in income will be an amount equal to the sum of the daily
portions of OID for each day during the taxable year in which the exchange
notes are held.

   The daily portions of OID are determined by allocating to each day in an
accrual period (which may be of any length and may vary over the term of the
exchange notes, at the option of the holder, provided that each accrual period
is no longer than one year and each scheduled payment of principal or interest
on the exchange notes occurs on the first or last day of an accrual period) the
pro rata portion of the OID allocable to the accrual period. The amount of OID
that is allocable to an accrual period generally will be the excess of the
product of the adjusted issue price of the exchange note at the beginning of
the accrual period (the issue price of the exchange note determined as
described above, generally increased by all prior accruals of OID) and the
yield to maturity of the exchange note (calculated on a constant yield basis
appropriately adjusted for the length of the accrual period) over the stated
interest paid during the accrual period or on the first day of the succeeding
accrual period. In general, the constant yield method will result in a greater
portion of such discount being included in income in the later part of the term
of the exchange note. Any amount of OID included in income will increase a U.S.
holder's tax basis in the exchange notes.

   Equinix is required to furnish certain information to the IRS, and will
furnish annually to record holders of exchange notes, information relating to
OID accruing during the calendar year. That information will be based upon the
adjusted issue price of the initial notes that were exchanged for the exchange
notes as if the holder were the original holder of the initial notes.

                                       93
<PAGE>

   A U.S. holder who purchases an exchange note for an amount other than the
adjusted issue price of the initial notes and/or on a date other than the end
of an accrual period will be required to determine for itself the amount of
OID, if any, it is required to include in gross income for U.S. federal income
tax purposes.

   Optional Redemption. Under the Treasury Regulations, for purposes of
computing OID, Equinix will be presumed to exercise its option to redeem the
exchange notes if, by utilizing the date of exercise of the call option as the
maturity date and the redemption price as the stated redemption price at
maturity, the yield on the exchange notes would be lower than such yield would
be if the option were not exercised. See "Description of the Exchange Notes--
Optional Redemption."

   If Equinix's option to redeem the exchange notes were presumed exercised on
a given date (the "Presumed Exercise Date"), the exchange notes would bear
additional OID in an amount equal to the amount for which the exchange notes
could be redeemed (the "Redemption Amount") over their issue price. For
purposes of calculating the current inclusion of such discount, the yield on
the exchange notes would be computed on their issue date by treating the
Presumed Exercise Date as the maturity date of the exchange notes and the
Redemption Amount as their stated principal amount due at maturity. If
Equinix's option to redeem the exchange notes were presumed exercised but were
not exercised in fact on the Presumed Exercise Date, the exchange notes would
be treated, for certain purposes, as if the option were exercised and new debt
instruments were issued on the Presumed Exercise Date for an amount of cash
equal to the Redemption Amount. In such case, it appears that any payment of
stated interest due under the exchange notes after the Presumed Exercise Date
would constitute qualified stated interest (rather than OID) and would be
taxable as ordinary interest income at the time such interest was accrued or
was received, in accordance with such U.S. holder's regular method of
accounting for tax purposes.

   Market Discount and Bond Premium. If a U.S. holder purchases exchange notes
or has purchased initial notes for an amount that is less than the adjusted
issue price of such exchange notes or initial notes, as the case may be, the
amount of difference will generally be treated as market discount for U.S.
Federal income tax purposes. In such case, any principal payment on and gain
realized on the sale, exchange or retirement of the exchange notes and
unrealized appreciation on certain nontaxable dispositions of the exchange
notes will be treated as ordinary income to the extent of any market discount
that has not previously been included in gross income and that is treated as
having accrued on such exchange notes or initial notes that were exchanged for
such exchange notes, by the time of such payment or disposition. If a U.S.
holder makes a gift of exchange notes, accrued market discount, if any, will be
recognized as if such holder has sold such exchange notes for a price equal to
their fair market value. In addition, the U.S. holder may be required to defer,
until the maturity of the exchange notes or their earlier disposition in a
taxable transaction, the deduction of a portion of the interest expense on any
indebtedness incurred or continued to purchase or carry such exchange notes or
initial notes that were exchanged for such exchange notes.

   Unless the U.S. holder elects to treat market discount as accruing on a
constant yield method, market discount will be treated as accruing on a
straight-line basis over the remaining term of the exchange notes. An election
made to include market discount in income as it accrues will apply to all debt
instruments acquired by the U.S. holder on or after the first day of the first
taxable year to which such election applies and may be revoked only with the
consent of the IRS.

   If a U.S. holder purchases an exchange note for an amount in excess of all
amounts payable on the exchange note after the purchase date, other than
payments of stated interest, such excess will be treated as bond premium. In
general, a U.S. holder may elect to amortize bond premium over the remaining
term of the exchange note on a constant yield method. The amount of bond
premium allocable to any accrual period is offset against the stated interest
allocable to such accrual period (any excess may be deducted, subject to
certain limitations). An election to amortize bond premium applies to all
taxable debt instruments held at the beginning of the first taxable year to
which such election applies and thereafter acquired by the U.S. holder and may
be revoked only with the consent of the IRS.

   Sale or Retirement of Exchange Notes. Upon the sale, retirement, redemption
or other taxable disposition of exchange notes, a U.S. holder will generally
recognize gain or loss in an amount equal to the difference between (a) the
amount of cash and the fair market value of other property received in exchange
therefor (other than amounts attributable to accrued but unpaid stated
interest) and (b) the U.S. holder's adjusted tax basis in such exchange notes.
Any gain or loss recognized will generally be capital gain or loss, and such
capital gain or loss will generally be long-term capital gain or loss if the
exchange notes have been held by the U.S. holder for more than one year
(including, in the case of a U.S. holder who acquired the exchange notes in
exchange for initial notes, the period of time the initial notes were held by
such U.S. holder) and otherwise will be a short-term capital gain or loss.

   A U.S. holder's tax basis in an exchange note that was acquired in exchange
for an initial note that was in turn acquired in the initial issuance from
Equinix will generally be equal to the issue price allocated to such initial
note as described above under "--The Exchange Notes--Original Issue Discount",
increased by the amount of OID, if any, included in gross income before the
date of the disposition, and decreased by the amount of any payment, other than
stated interest, on such note before disposition.

   U.S. holders should be aware that the resale of the exchange notes may be
affected by the market discount rules of the Code as described above under "--
The Exchange Notes--Market Discount and Bond Premium" under which a purchaser
of an initial note or an exchange note acquiring such note at a market discount
generally would be required to include as ordinary income a portion of the gain
realized upon the disposition or retirement of such note, to the extent of the
market discount that has accrued but not been included in income while such
note was held by such purchaser.

Non-U.S. Holders

   Interest or redemption proceeds paid to non-U.S. holders of the exchange
notes generally will not be subject to U.S. Federal withholding tax provided
that (a) the non-U.S. holder does not actually or constructively own 10 percent
or more of a total combined voting power of all classes of stock of Equinix
entitled to vote, (b) the non-U.S. holder is not a "controlled foreign
corporation" (within the meaning of the Code) that is related to Equinix
through stock ownership, (c) either (1) the beneficial owner of the exchange
notes provides Equinix or its agent with a statement signed under penalties of
perjury that includes its name and address and certifies that it is not a
United States person or (2) a securities clearing organization, bank, or other
financial institution that holds customers' securities in the ordinary course
of its business (a "financial institution") certifies to Equinix or its agent,
under penalties of perjury, that such a statement has been received from the
beneficial owner by it or another financial institution and furnished to
Equinix or its agent a copy of the statement and (d) the exchange notes are in
registered form. If these requirements cannot be met, a non-U.S. holder will be
subject to U.S. withholding tax at a rate of 30 percent (or lower treaty rate,
if applicable) on interest payments. Although U.S. tax will also be imposed
against OID on the exchange notes before payment, such tax will only be
withheld from stated interest payments on the exchange notes. However, such
additional withholding may result in U.S. withholding tax on stated interest
payments exceeding 30 percent.

   In general, any gain realized by any non-U.S. Holder upon the sale, exchange
or redemption of an exchange note will not be subject to Federal income or
withholding tax unless (i) a non-U.S. holder is an individual and is present in
the U.S. for a total of 183 days or more during the taxable year in which the
gain is realized, (ii) the gain is effectively connected with the conduct of a
trade or business of the holder in the U.S., or in the case of certain
residents of countries which have an income tax treaty in force with the U.S.,
attributable to a permanent establishment (or in the case of an individual a
fixed base) in the U.S. as such terms are defined in the applicable tax treaty,
(iii) the holder is subject to tax in accordance with the provisions of U.S.
tax law applicable to certain U.S. expatriates (including certain former
citizens or residents of the U.S.) or (iv) Equinix is or has been a "United
States real property holding corporation" at any time within the shorter of the
five-year period preceding such disposition or such holder's holding period.
Equinix does not believe that is its currently a "United States real property
holding corporation", or that it will become one in the future.

Deductibility of Interest and Original Issue Discount

   The Code contains various limitations and restrictions on the deductibility
of interest and/or OID. Some of these limitations and restrictions may be
applicable to the interest and/or the OID associated with the notes. In such
event, some or all of the interest or OID associated with the notes may not be
deductible by Equinix.

Information Reporting and Backup Withholding

   In general information reporting requirements will apply to OID, payments of
principal, premium, if any, and interest on the exchange notes and payments of
the proceeds of the sale of the exchange notes, and a 31% backup withholding
tax may apply to such payments if the holder either (i) fails to demonstrate
that the holder comes within certain exempt categories of holders or (ii) fails
to furnish or certify his correct taxpayer identification number to the payer
in the manner required, is notified by the IRS that he has failed to report
payments of interest and dividends properly, or under certain circumstances,
fails to certify that he has not been notified by the IRS that he is subject to
backup withholding for failure to report interest and dividend payments. Any
amounts withheld under the backup withholding rules from a payment to a holder
will be allowed as a credit against such holder's United States federal income
tax and may entitle the holder to a refund, provided that the required
information is furnished to the IRS.

                              PLAN OF DISTRIBUTION

   Each broker-dealer that receives exchange notes for its own account in the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of those exchange notes. This prospectus, as it may be amended
or supplemented from time to time, may be used by a broker-dealer in connection
with resales of exchange notes received in the exchange offer where the
outstanding exchange notes were acquired as a result of market-making
activities or other trading activities. We have agreed that, for a period of
180 days after the consummation of the exchange offer, we will make this
prospectus, as amended and supplemented, available to any broker-dealer for use
in connection with any such resale. In addition, until   , 2000, all dealers
effecting transactions in the exchange notes issued in the exchange offer may
be required to deliver a prospectus.

   We will not receive any proceeds from any sale of exchange notes by broker-
dealers. exchange notes received by broker-dealers for their own account in the
exchange offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the exchange notes or a combination of such methods of resale, at
market prices prevailing at the time of resale, at prices related to such
prevailing market prices or at negotiated prices. Any such resale may be made
directly to purchasers or to or though brokers or dealers who may receive
compensation in the form of commissions or concessions from any such broker-
dealer or the purchasers of any such exchange notes. Any broker-dealer that
resells exchange notes that were received by it for its own account in the
exchange offer and any broker or dealer that participates in a distribution of
such exchange notes may be deemed to be an "underwriter" within the meaning of
the Securities Act, and profit on any such resale of exchange notes issued in
the exchange and any commission or concessions received by any such persons may
be deemed to be underwriting compensation under the Securities Act. The letter
of transmittal states that, by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.

   For a period of 180 days after the consummation of the exchange offer, we
will promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay all expenses incident to
the exchange offer, including the expenses of one counsel for the holders of
the exchange notes, other than the commissions or concessions of any broker-
dealers and will indemnify the holders of the exchange notes, including any
broker-dealers, against certain liabilities, including liabilities under the
Securities Act. We note, however, that, in the opinion of the SEC,
indemnification against liabilities arising under federal securities laws is
against public policy and may be unenforceable.

                                 LEGAL MATTERS

   Legal matters as to the validity of the exchange notes offered by this
prospectus will be passed on for us by Dewey Ballantine LLP, New York, New York
and Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, Menlo Park,
California. As of the date of this prospectus, some partners and employees of
Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, our outside
corporate counsel, beneficially owned an aggregate of 84,375 shares of our
capital stock.

                       Report of Independent Accountants

The Board of Directors and Stockholders of Equinix, Inc.

   In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash
flows present fairly, in all material respects, the financial position of
Equinix, Inc. as of December 31, 1998 and 1999, and the results of its
operations and its cash flows for the period from June 22, 1998 (date of
inception) to December 31, 1998 and for the year ended December 31, 1999, in
conformity with accounting principles generally accepted in the United States.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)Nature of Business and Summary of Significant Accounting Policies

  Nature of Business

     Equinix, Inc. ("Equinix" or the "Company") was incorporated as Quark
  Communications, Inc. in Delaware on June 22, 1998. The Company changed its
  name to Equinix, Inc. on October 13, 1998. Equinix designs, builds, and
  operates neutral Internet Business Exchange ("IBX") centers.

     For the period June 22, 1998 (inception) through December 31, 1998 and
  the period ended September 30, 1999, the Company was a development stage
  enterprise. Subsequent to this period, the Company opened its second IBX
  center for commercial operation. In addition, the Company began to
  recognize revenue from its IBX centers. As a result, the Company is no
  longer a development stage enterprise as of and for the year ended December
  31, 1999.

  Stock Split

     In January 2000, the Company's stockholders approved a three-for-two
  stock split effective January 19, 2000 whereby three shares of common stock
  and redeemable convertible preferred stock were exchanged for every two
  shares of common stock and redeemable convertible preferred stock then
  outstanding. All share and per share amounts in these financial statements
  have been adjusted to give effect to the stock split (see Note 11).

  Unaudited Interim Results

     The accompanying consolidated balance sheet as of March 31, 2000, the
  consolidated statements of income and of cash flows for the three months
  ended March 31, 1999 and 2000 and the consolidated statement of
  stockholders' equity for the three months ended March 31, 2000 are
  unaudited.

     In the opinion of management, these statements have been prepared on the
  same basis as the audited financial statements and include all adjustments,
  consisting only of normal recurring adjustments, necessary for the fair
  presentation of the Company's financial position as of March 31, 2000 and
  the results of its operations and cash flows for the three month periods
  ended March 31, 1999 and 2000. The data disclosed in notes to the
  consolidated financial statements for these periods is unaudited.

  Basis of Presentation

     The accompanying consolidated financial statements include the accounts
  of Equinix and its wholly-owned subsidiary, Equinix-DC, Inc. ("Equinix-
  DC"). All significant intercompany accounts and transactions have been
  eliminated in consolidation.

  Use of Estimates

     The preparation of consolidated financial statements in conformity with
  generally accepted accounting principles requires management to make
  estimates and assumptions that affect the reported amounts of assets and
  liabilities and disclosure of contingent assets and liabilities at the date
  of the consolidated financial statements and the reported amounts of
  revenues and expenses during the reporting period. Actual results could
  differ from these estimates.

  Cash, Cash Equivalents and Short-Term Investments

     The Company considers all highly liquid instruments with a maturity from
  the date of purchase of three months or less to be cash equivalents. Cash
  equivalents consist of money market mutual funds and certificates of
  deposit with financial institutions with maturities of between 7 and 60
  days. Short-term investments generally consist of certificates of deposits
  with maturities of between 90 and 180 days and highly liquid debt and
  equity securities of corporations, municipalities and the U.S. government.
  Short-term investments are classified as "available-for-sale" and are
  carried at fair value based on quoted

                                 EQUINIX, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  market prices, with unrealized gains and losses reported in stockholders'
  equity as a component of comprehensive income. The cost of securities sold
  is based on the specific identification method.

  Restricted Cash and Short-term Investments

     Restricted cash and short-term investments as of December 31, 1999
  consists of $37,011,500, plus accrued interest of $67,100, deposited with
  an escrow agent to pay the first three interest payments on the Senior
  Notes (see Note 4) and restricted cash of $1,530,100 provided as collateral
  under three separate security agreements for standby letters of credit
  entered into and in accordance with certain lease agreements. Restricted
  cash and short-term investments as of March 31, 2000 consists of
  $37,011,500, plus accrued interest of $554,500, deposited with an escrow
  agent to pay the first three interest payments on the Senior Notes (see
  Note 4) and restricted cash of $3,451,200, plus accrued interest of $35,900
  for four standby letters of credit and an escrow account entered into and
  pursuant to certain lease agreements. These agreements expire at various
  dates through 2014.

  Financial Instruments and Concentration of Credit Risk

     Financial instruments, which potentially subject the Company to
  concentrations of credit risk, consist of cash, cash equivalents and short-
  term investments to the extent these exceed federal insurance limits and
  accounts receivable. Risks associated with cash, cash equivalents and
  short-term investments are mitigated by the Company's investment policy,
  which limits the Company's investing to only those marketable securities
  rated at least A-1 or P-1 investment grade, as determined by independent
  credit rating agencies.

     The Company's customer base is primarily composed of businesses
  throughout the United States. The Company performs ongoing credit
  evaluations of its customers.

  Property and Equipment

     Property and equipment are stated at original cost. Depreciation is
  computed using the straight-line method over the estimated useful lives of
  the respective assets, generally two to five years for non-IBX center
  equipment and seven to ten years for IBX center equipment. Leasehold
  improvements and assets acquired under capital lease are amortized over the
  shorter of the lease term or the estimated useful life of the asset or
  improvement.

  Construction in Progress

     Construction in progress includes direct and indirect expenditures for
  the construction of IBX centers and is stated at original cost. The Company
  has contracted out substantially all of the construction of the IBX centers
  to independent contractors under construction contracts. Construction in
  progress includes certain costs incurred under a construction contract
  including project management services, site identification and evaluation
  services, engineering and schematic design services, design development and
  construction services and other construction-related fees and services. In
  addition, the Company has capitalized certain interest costs during the
  construction phase. Once an IBX center becomes operational, these
  capitalized costs are depreciated at the appropriate rate consistent with
  the estimated useful life of the underlying asset.

     Included within construction in progress is the value attributed to the
  unearned portion of the WorldCom warrant and the Bechtel warrant totaling
  $2,639,100 and $1,497,200, respectively, as of December 31, 1999 and
  $1,802,100 and $2,657,000, respectively, as of March 31, 2000 (See Note 6).

     Interest incurred is capitalized in accordance with Statement of
  Financial Accounting Standards ("SFAS") No. 34, Capitalization of Interest
  Costs. Total interest cost incurred and total interest

                                      F-8
<PAGE>

                                 EQUINIX, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  capitalized during the year ended December 31, 1999, was $3,323,600 and
  $177,400, respectively. Total interest cost incurred and total interest
  capitalized during the three months ended March 31, 2000, was $7,512,800
  and $193,600, respectively.

  Fair value of Financial Instruments

     The carrying value of the Company's financial instruments, which include
  cash equivalents, short-term investments, accounts receivable, accounts
  payable, accrued expenses and long-term obligations approximate their fair
  value due to either the short-term maturity or the previaling interest
  rates of the related instruments.

  Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of

     In accordance with SFAS No. 121, Accounting for the Impairment of Long-
  Lived Assets and for Long-Lived Assets to Be Disposed Of, the Company
  considers the impairment of long-lived assets and certain identifiable
  intangibles whenever events or changes in circumstances indicate that the
  carrying amount of such assets may not be recoverable. Recoverability of
  assets to be held and used is measured by a comparison of the carrying
  amount of an asset to future net cash flows expected to be generated by the
  asset. If such assets are considered to be impaired, the impairment to be
  recognized is measured by the amount by which the carrying amount of the
  assets exceeds the fair value of the assets. Assets to be disposed of are
  reported at the lower of the carrying amount or fair value less costs to
  sell. No impairment of long-lived assets has been recorded as of December
  31, 1998 and 1999.

  Revenue Recognition

     Revenues consist of monthly recurring fees for colocation and
  interconnection services at the IBX centers, service fees associated with
  the delivery of professional services and non-recurring installation fees.
  Revenues from colocation and interconnection services are billed monthly
  and recognized ratably over the term of the contract, generally one to
  three years. Professional service fees are recognized in the period in
  which the services were provided and represent the culmination of the
  earnings process. Non-recurring installation fees are deferred and
  recognized ratably over the term of the related contract.

  Income Taxes

     Income taxes are accounted for under the asset and liability method.
  Deferred tax assets and liabilities are recognized for the future tax
  consequences attributable to differences between financial statement
  carrying amounts of existing assets and liabilities and their respective
  tax bases and operating loss and tax credit carryforwards. Deferred tax
  assets and liabilities are measured using enacted tax rates expected to
  apply to taxable income in the years in which those temporary differences
  are expected to be recovered or settled. The effect on deferred tax assets
  and liabilities of a change in tax rates is recognized in income in the
  period that includes the enactment date. Valuation allowances are
  established when necessary to reduce tax assets to the amounts expected to
  be realized.

  Stock-Based Compensation

     The Company accounts for its stock-based compensation plans in
  accordance with SFAS No. 123, Accounting for Stock-Based Compensation. As
  permitted under SFAS No. 123, the Company uses the intrinsic value-based
  method of Accounting Principles Board ("APB") Opinion No. 25, Accounting
  for Stock Issued to Employees, to account for its employee stock-based
  compensation plans.

     The Company accounts for stock-based compensation arrangements with
  nonemployees in accordance with the Emerging Issues Task Force Abstract
  ("EITF") No. 96-18, Accounting for Equity

                                      F-9

                                 EQUINIX, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  Instruments That Are Issued to Other Than Employees for Acquiring, or in
  Conjunction with Selling Goods or Services. Accordingly, unvested options
  and warrants held by nonemployees are subject to revaluation at each
  balance sheet date based on the then current fair market value.

     Unearned deferred compensation resulting from employee and nonemployee
  option grants is amortized on an accelerated basis over the vesting period
  of the individual options, in accordance with FASB Interpretation No. 28,
  Accounting for Stock Appreciation Rights and Other Variable Stock Option or
  Award Plans ("FASB Interpretation No. 28").

  Segment Reporting

     The Company has adopted the provisions of SFAS No. 131, Disclosures
  about Segments of an Enterprise and Related Information. SFAS No. 131
  establishes annual and interim reporting standards for operating segments
  of a company. The statement requires disclosures of selected segment-
  related financial information about products, major customers and
  geographic areas.

  Comprehensive Income

     The Company has adopted the provisions of SFAS No. 130, Reporting
  Comprehensive Income. SFAS No. 130 establishes standards for the reporting
  and display of comprehensive income and its components; however, the
  adoption of this statement had no impact on the Company's net loss or
  stockholders' equity. SFAS 130 requires unrealized gains or losses on the
  Company's available-for-sale securities to be included in other
  comprehensive income (loss). Comprehensive income (loss) consists of net
  loss and other comprehensive income.

  Recent Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued SFAS No.
  133, Accounting for Derivative Instruments and Hedging Activities. SFAS No.
  133 establishes accounting and reporting standards for derivative
  instruments, including derivative instruments embedded in other contracts,
  and for hedging activities. SFAS No. 133, as amended by SFAS No. 137,
  Deferral of the Effective Date of FASB Statement No. 133, is effective for
  all fiscal quarters of fiscal years beginning after September 15, 2000.
  This statement does not currently apply to the Company as the Company does
  not have any derivative instruments or hedging activities.

     In December 1999, the SEC issued Staff Accounting Bulletin ("SAB") 101,
  Revenue Recognition, which outlines the basic criteria that must be met to
  recognize revenue and provides guidance for presentation of revenue and for
  disclosure related to revenue recognition policies in financial statements
  filed with the SEC. The Company believes the adoption of SAB 101 will not
  have a material impact on the Company's financial position and results of
  operations.

     In March 2000, the FASB issued Interpretation No. 44, ("FIN 44"),
  Accounting for Certain Transactions Involving Stock Compensation - an
  Interpretation of APB 25. This Interpretation clarifies (a) the definition
  of employee for purposes of applying Opinion 25, (b) the criteria for
  determining whether a plan qualifies as a noncompensatory plan, (c) the
  accounting consequence of various modifications to the terms of a
  previously fixed stock option or award, and (d) the accounting for an
  exchange of stock compensation awards in a business combination. This
  Interpretation is effective July 1, 2000, but certain conclusions in this
  Interpretation cover specific events that occur after either December 15,
  1998, or January 12, 2000. To the extent that this Interpretation covers
  events occurring during the period after December 15, 1998, or January 12,
  2000, but before the effective date of July 1, 2000, the effects of
  applying this Interpretation are recognized on a prospective basis from
  July 1, 2000. The Company has not yet determined the impact, if any, of
  adopting this interpretation.

  Comdisco Loan and Security Agreement

     In March 1999, Equinix-DC entered into a $7,000,000 Loan and Security
  Agreement with Comdisco, Inc. ("Comdisco" and the "Comdisco Loan and
  Security Agreement"). Under the terms of the Comdisco Loan and Security
  Agreement, Comdisco may lend the Company up to $3,000,000 for equipment
  (referred to as the "hard" loan) and up to $4,000,000 for software and
  tenant improvements ("soft" loan) for the Ashburn, Virginia IBX center
  buildout. The loans, which are collateralized by the assets of the Ashburn
  IBX, are available in minimum advances of $1,000,000 and each loan is
  evidenced by a secured promissory note. The hard and soft loans issued bear
  interest at rates of 7.5% and 9% per annum, respectively, and are repayable
  in 42 and 36 equal monthly installments, respectively, plus a final balloon
  interest payment equal to 15% of the original advance amount due at
  maturity. The Comdisco Loan and Security Agreement has an effective
  interest rate of 18.1% per annum. As of December 31, 1999, $5,042,000 was
  outstanding under the Comdisco Loan and Security Agreement.

     In connection with the Comdisco Loan and Security Agreement, the Company
  granted Comdisco a warrant to purchase 765,000 shares of the Company's
  Series A preferred stock at $0.67 per share (the "Comdisco Loan and
  Security Agreement Warrant"). This warrant is immediately exercisable and
  expires in ten years from the date of grant. The fair value of the warrant,
  using the Black-Scholes option pricing model with the following
  assumptions: deemed fair market value per share of $1.80, dividend yield of
  0%, expected volatility of 80%, risk-free interest rate of 5.0% and a
  contractual life of 10 years, was $1,255,000, was recorded as a discount to
  the applicable debt, and is being amortized to interest expense, using the
  effective interest method, over the life of the agreement.

  leaseback transactions. The Company has deferred a gain of $77,700 related
  to the sale-leaseback in July 1999, which is being amortized in proportion
  to the amortization of the leased assets.

     In connection with the Comdisco Master Lease Agreement, the Company

  back. The amount of financing available under the Comdisco Master Lease
  Agreement Addendum is up to $2,150,000 for hard items and up to $2,850,000
  for soft items. Amounts drawn under this addendum will be collateralized by
  the underlying hard and soft assets of the San Jose IBX center that were
  funded under the Comdisco Master Lease Agreement Addendum. Repayments are
  made monthly over the course of 42 months. Interest accrues at 8.5% per
  annum, with a final balloon interest payment equal to 15% of the original

(4)Senior Notes and Debt Issuance Costs

     On December 1, 1999, the Company issued 200,000 units, each consisting
  of a $1,000 principal amount 13% Senior Note due 2007 (the "Senior Notes")
  and one warrant to purchase 16.8825 shares (for an aggregate of 3,376,500
  shares) of common stock for $0.0067 per share (the "Senior Note Warrants"),
  for aggregate net proceeds of $193,400,000, net of offering expenses. Of
  the $200,000,000 gross proceeds, $16,207,200 was allocated to additional
  paid-in capital for the deemed fair value of the Senior Note Warrants and
  recorded as a discount to the Senior Notes. The discount on the Senior
  Notes is being amortized to interest expense, using the effective interest
  method, over the life of the debt. The Senior Notes have an effective
  interest rate of 14.1% per annum. The fair value attributed to the Senior
  Note Warrants was consistent with the Company's treatment of its other
  common stock transactions prior to the issuance of the Senior Notes. The
  fair value was based on recent equity transactions by the Company. The
  amount of the Senior Notes, net of the unamortized discount, is
  $183,954,700 as of December 31, 1999.

     As of December 31, 1999, restricted cash and short-term investments,
  including accrued interest thereon, includes $37,078,600 deposited with an
  escrow agent that will be used to pay the first three interest payments.
  Interest is payable semi-annually, in arrears, on June 1 and December 1 of
  each year, commencing on June 1, 2000. The Senior Notes are partially
  collateralized by the restricted cash and short-term investments. Except
  for this security interest, the notes are unsecured, senior obligations of
  the Company and are effectively subordinated to all existing and future
  indebtedness of the Company, whether or not secured.

     The Senior Notes are governed by the Indenture dated December 1, 1999,
  between the Company, as issuer, and State Street Bank and Trust Company of
  California, N.A., as trustee (the "Indenture"). Subject to certain
  exceptions, the Indenture restricts, among other things, the Company's
  ability to incur additional indebtedness and the use of proceeds therefrom,
  pay dividends, incur certain liens to secure indebtedness or engage in
  merger transactions.

     The costs related to the issuance of the Senior Notes were capitalized
  and are being amortized to interest expense using the effective interest
  method, over the life of the Senior Notes. Debt issuance costs, net of
  amortization, are $7,125,800 as of December 31, 1999.

     There was no activity between December 31, 1999 and March 31, 2000. Also
  included in redeemable convertible preferred stock is the fair value of
  1,245,000 Series A warrants issued in connection with various debt and
  capital lease facilities (see Note 3).

     On September 10, 1998, 15,037,500 shares of Series A preferred stock
  were issued at a price of $0.67 per share. Concurrent with the issuance of
  the Series A preferred stock, promissory notes of $220,000 were converted
  into 660,000 shares of Series A preferred stock. During July 1998, the
  Company had borrowed $220,000 in the aggregate under a convertible loan
  arrangement with a number of individual investors. The loans accrued
  interest of 5.83% per annum while outstanding, which was paid in cash.
  During the period ended December 31, 1998, the Company recorded a charge of
  $220,000 to account for the "in the money" conversion right of the
  convertible loan arrangement. On January 27, 1999, 3,000,000 shares of
  Series A preferred stock were issued, at a price of $0.67 per share in the
  second closing of the Series A financing.

     Between August and December 1999, the Company completed its Series B
  preferred stock financing. The Company issued 15,762,373 shares of Series B
  preferred stock, at a price of $5.33 per share.

     The rights, preferences, and privileges of the Series A and Series B
  preferred stock are as follows:

    .  Dividends are noncumulative and are payable only upon declaration by
       the Board of Directors at a rate of $0.05 and $0.43 per share for
       Series A and B, respectively. No dividends have been declared to
       date.

    .  Holders of Series A and B preferred stock have a liquidation
       preference of $0.67 and $5.33 per share, respectively, plus all
       declared but unpaid dividends. A consolidation, merger or sale of the
       Company will be deemed to be a liquidation, dissolution or winding up
       of the Company for purposes of liquidation rights.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


    .  Each share of Series A and B preferred stock is convertible, at the
       option of the holder, into common stock at a conversion price equal
       to the respective original preferred stock issue price. The
       conversion price is subject to adjustment for stock splits and
       combinations and will automatically convert into common stock in the
       event of either (i) an underwritten public offering with an
       aggregate gross offering price of at least $25,000,000 or (ii) upon
       a vote of the holders of a majority of the then outstanding shares
       of each class of preferred stock.

    .  Each share of Series A and Series B preferred stock has voting
       rights equal to that of common stock on an "as if converted" basis.

    .  The holders of Series A and B preferred stock are entitled to elect
       two and one directors, respectively, to the Company's Board of
       Directors so long as 25% of the shares of Series A and B preferred
       stock originally issued remain outstanding.

    .  Series A and B preferred stock is not redeemable at any time, except
       in the case of an acquisition by another entity that results in the
       transfer of fifty percent or more of the outstanding voting power of
       the corporation or a sale of all or substantially all of the assets
       of the corporation. Effectively, this change in control would
       provide for the preferred stockholder to present their security for
       cash redemption.

    .  Holders of greater than 1,500,000 shares of Series A and/or Series B
       preferred stock have the right to purchase their pro rata share of
       securities subsequently sold or otherwise issued by the Company,
       subject to standard exceptions.

    .  Holders of Series A and Series B preferred stock have the right to
       veto:

              . any increase in the number of Series B preferred stock or the
                issuance of any securities with rights senior to those of the
                Series B preferred stock;

              . the redemption of any securities by the Company, other than in
                connection with an employee's termination of employment; and

              . any increase to the size of the Company's board of directors.

    .  Holders of Series A and Series B preferred stock may require the
       Company to file a registration statement with the SEC to register

  Stock Option Plan

     In September 1998, the Company adopted the 1998 Stock Plan (the "Plan")
  under which nonstatutory stock options and restricted stock may be granted
  to employees, outside directors, and consultants, and incentive stock
  options may be granted to employees. Accordingly, the Company has reserved
  a total of 8,262,810 shares of the Company's common stock for issuance upon
  the grant of restricted stock or exercise of options granted in accordance
  with the Plan. Options granted under the Plan generally expire 10 years
  following the date of grant and are subject to limitations on transfer. The
  Plan is administered by the Board of Directors.

     The Plan provides for the granting of incentive stock options at not
  less than 100% of the fair market value of the underlying stock at the
  grant date. Nonstatutory options may be granted at not less than 85% of the
  fair market value of the underlying stock at the date of grant.

     Option grants under the Plan are subject to various vesting provisions,
  all of which are contingent upon the continuous service of the optionee and
  may not impose vesting criterion more restrictive than 20% per year. Stock
  options may be exercised at anytime subsequent to grant. Stock obtained
  through exercise of unvested options is subject to repurchase at the
  original purchase price. The Company's repurchase right decreases as the
  shares vest under the original option terms.

     Options granted to stockholders who own greater than 10% of the
  outstanding stock must have vesting periods not to exceed five years and
  must be issued at prices not less than 110% of the fair market value of the
  stock on the date of grant as determined by the Board of Directors. Upon a
  change of control, all shares granted under the Plan shall immediately
  vest. Unless otherwise terminated by the Board of Directors, the Plan
  automatically terminates in September 2008.

     A summary of the Plan is as follows:

  Stock-Based Compensation

  Employees

     The Company uses the intrinsic-value method prescribed in APB No. 25 in
  accounting for its stock-based compensation arrangements with employees.
  Stock-based compensation expense is recognized for employee stock option
  grants in those instances in which the deemed fair value of the underlying
  common stock was subsequently determined to be greater than the exercise
  price of the stock options at the date of grant. The Company recorded
  deferred stock-based compensation related to employees of $19,785,800 in
  respect to stock options granted through December 31, 1999, of which
  $135,300 and $6,067,300 has been amortized to stock-based compensation
  expense for the period and year ended December 31, 1998 and 1999,
  respectively, on an accelerated basis over the vesting period of the
  individual options, in accordance with FASB Interpretation No. 28. For the
  three months ended March 31, 2000, the Company recorded additional deferred
  stock-based compensation related to employees of $4,200,600, in respect of
  stock option grants during the three months ended March 31, 2000. During
  the three months ended March 31, 2000, the Company amortized $2,941,200 of
  compensation related to employees to stock-based compensation expense, on
  an accelerated basis in accordance with FASB Interpretation No. 28.

     Had compensation costs been determined using the fair value method for
  the Company's stock-based compensation plans, net loss would have been
  changed to the amounts indicated below:

     The Company's calculations for employee grants were made using the
  minimum value method with the following weighted average assumptions for
  the period from June 22, 1998 (inception) to December 31, 1998 and the year
  ended December 31, 1999: dividend yield of 0%; expected volatility of 0%;
  risk-free interest rates of 5.77% in the period from June 22, 1998
  (inception) to December 31, 1998 and 5.66% in the year ended December 31,
  1999; and expected lives of 2.67 years in the period from June 22, 1998
  (inception) to December 31, 1998 and 2.52 years in the year ended December
  31, 1999.

  Non-Employees

     The Company uses the fair value method to value options granted to non-
  employees. In connection with its grant of options to non-employees, the
  Company has recognized deferred stock-based compensation of $710,900 and
  $695,000 through December 31, 1999 and for the three months ended March 31,
  2000, respectively, of which $28,600, $560,000 and $540,500 has been
  amortized to stock-based compensation expense for the period and year ended
  December 31, 1998 and 1999, respectively, and for the three months ended
  March 31, 2000, respectively, on an accelerated basis over the vesting
  period of the individual options, in accordance with FASB Interpretation
  No. 28.

     The Company's calculations for non-employee grants were made using the
  Black-Scholes option pricing model with the following weighted average
  assumptions for the period from June 22, 1998 (inception) to December 31,
  1998, the year ended December 31, 1999 and the three month period ended
  March 31, 2000: dividend yield of 0%; expected volatility of 80%; risk-free
  interest rates of 4.99% in the period from June 22, 1998 (inception) to
  December 31, 1998, 5.48% in the year ended December 31, 1999 and 5.51% in
  the three month period ended March 31, 2000; and contractual life of
  10 years.

  Warrants

     In August 1999, the Company entered into a strategic agreement with
  NorthPoint Communications, Inc. ("NorthPoint"). Under the terms of the
  strategic agreement, NorthPoint has agreed to use certain of the Company's
  domestic IBX centers and install their operational nodes in such centers.
  In exchange, the Company granted NorthPoint a warrant to purchase 338,145
  shares of the Company's common stock at $0.53 per share (the "NorthPoint
  Warrant"). The NorthPoint Warrant was earned upon execution of the
  strategic agreement as Northpoint's performance commitment was complete.
  The NorthPoint Warrant is immediately exercisable and expires five years
  from date of grant. The NorthPoint Warrant was valued at $1,507,800 using
  the Black-Scholes option-pricing model, which was capitalized on the
  accompanying consolidated balance sheet in other assets as a customer
  acquisition cost and is being amortized over the term of the agreement as a
  reduction of revenues recognized. The following assumptions were used in
  determining the fair value of the warrant: deemed fair market value per
  share of $4.80, dividend yield of 0%, expected volatility of 80%, risk-free
  interest rate of 5.0% and a contractual life of 5 years.

     In November 1999, the Company entered into a definitive agreement with
  WorldCom whereby WorldCom agreed to install high-bandwidth local
  connectivity services to the Company's first seven IBX centers by a pre-
  determined date in exchange for a warrant to purchase 675,000 shares of
  common stock of the Company at $0.67 per share (the "WorldCom Warrant").
  The WorldCom Warrant is immediately exercisable and expires five years from
  the date of grant. As of December 31, 1999, warrants for 600,000 shares are
  subject to repurchase at the original exercise price if WorldCom's
  performance commitments are not completed. The WorldCom Warrant was valued
  at $2,969,000 using the Black-Scholes option-pricing model and was recorded
  to construction in progress on the accompanying consolidated balance sheet
  as of December 31, 1999. Under the applicable guidelines in EITF 96-18, the
  underlying shares of common stock associated with the WorldCom Warrant
  subject to repurchase are revalued at each balance sheet date to reflect
  their current fair value until WorldCom's performance commitment is
  complete. Any resulting increase in fair value of the warrants is recorded
  as a leasehold improvement. In addition, the following assumptions were
  used in determining the fair value of the warrant: deemed fair market value
  per share of $4.80, dividend yield of 0%, expected volatility of 80%, risk-
  free interest rate of 5.5% and a contractual life of 5 years.

     In November 1999, the Company entered into a master agreement with
  Bechtel Corporation, or Bechtel, whereby Bechtel agreed to act as the
  exclusive contractor under a Master Agreement to provide program
  management, site identification and evaluation, engineering and
  construction services to build

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  approximately 29 IBX centers over a four year period under mutually agreed
  upon guaranteed completion dates. As part of the agreement, the Company
  granted Bechtel a warrant to purchase 352,500 shares of the Company's
  common stock at $1.00 per share (the "Bechtel Warrant"). The Bechtel
  Warrant is immediately exercisable and expires five years from date of
  grant. As of December 31, 1999, warrants for 282,000 shares are subject to
  repurchase at the original exercise price, if Bechtel's performance
  commitments are not complete. The Bechtel Warrant was valued at $1,497,200
  using the Black-Scholes option-pricing model and was recorded to
  construction in progress on the accompanying consolidated balance sheet as
  of December 31, 1999. Under EITF 96-18, the underlying shares of common
  stock associated with the Bechtel Warrant subject to repurchase are
  revalued at each balance sheet date to reflect their current fair value
  until Bechtel's performance commitment is complete. Any resulting increase
  in fair value of the warrants is recorded as a leasehold improvement. In
  addition, the following assumptions were used in determining the fair value
  of the warrant: deemed fair market value per share of $4.80, dividend yield
  of 0%, expected volatility of 80%, risk-free interest rate of 5.5% and a
  contractual life of 5 years.

     In addition, the Company has issued several warrants in connection with
  its debt facilities and capital lease obligations (see Note 3) and the
  Senior Notes (see Note 4). The Company has the following warrants
  outstanding as of December 31, 1999:

(7) Income Taxes

   No provision for federal income taxes was recorded from inception through
December 31, 1999 as the Company incurred net operating losses during the
period.

   State tax expense is included in general and administrative expenses.

   Actual income tax expense differs from the expected tax benefit computed by
applying the statutory federal income tax rate of approximately 34% for the
periods ended December 31, 1998 and 1999 primarily as a result of the change in
valuation allowance and stock-based compensation.

</TABLE>

   The net change in the total valuation allowance for the period from June 22,
1998 (inception) to December 31, 1998 and the year ended December 31, 1999, was
an increase of $287,300 and $6,182,700, respectively.

   The Company has established a valuation allowance against that portion of
deferred tax assets where management has determined that it is more likely than
not that the asset will not be realized.

   At December 31, 1999, the Company had net operating loss carryforwards of
approximately $8,000,000 for federal and state tax purposes. If not earlier
utilized, the federal net operating loss carryforward will expire in 2019 and
the state loss carryforward will expire in 2006.

   Under the Tax Reform Act of 1986, the amounts of and the benefit from net
operating losses that can be carried forward may be or limited in certain
circumstances. Events that may cause limitations in the utilization of net
operating losses include, a cumulative stock ownership change of more than 50%
over a three year period and other events. Equinix has not yet determined the
extent that the net operating loss benefit will be limited.

(8) Commitments and Contingencies

  Operating Lease Commitments

     The Company leases its IBX centers and certain equipment under
  noncancelable operating lease agreements expiring through 2014. The
  centers' lease agreements typically provide for base rental rates which
  increase at defined intervals during the term of the lease. In addition,
  the Company has negotiated rent expense abatement periods to better match
  the phased build-out of its centers. The Company accounts for such
  abatements and increasing base rentals using the straight-line method over
  the life of the lease. The difference between the straight-line expense and
  the cash payment is recorded as deferred rent.

     Minimum future operating lease payments as of December 31, 1999 are
  summarized as follows:

     Total rent expense was approximately $165,000 and $1,739,100 for the
  period from June 22, 1998 (inception) to December 31, 1998 and for the year
  ended December 31, 1999, respectively.

     Deferred rent included in accrued expenses was $42,400 and $18,000 as of
  December 31, 1998 and 1999, respectively. Deferred rent included in other
  liabilities was none and $566,600 as of December 31, 1998 and 1999,
  respectively.

  Employment Agreement

     The Company has agreed to indemnify an officer of the Company for any
  claims brought by his former employer under an employment and non-compete
  agreement the officer had with this employer.

  Employee Benefit Plan

     During the year ended December 31, 1999, the Company adopted the Equinix
  401(k) Plan (the "401(k) Plan"). The 401(k) Plan allows eligible employees
  to contribute up to 15% of their compensation, limited to $10,000 in 1999.
  Employee contributions and earnings thereon vest immediately. Although the
  Company may make discretionary contributions to the 401(k) Plan, none have
  been made as of December 31, 1999.

(9) Related Party Transactions

     The Company advanced an aggregate of $750,000 to an officer of the
  Company, which is evidenced by a promissory note. The proceeds of this loan
  were used to fund the purchase of a personal residence. The loan is due
  September 13, 2004, but is subject to certain events of acceleration,
  including an initial public offering of the Company's common stock and is
  secured by a second deed of trust on the officer's residence. The loan is
  non-interest bearing. This loan is presented in other assets on the
  accompanying consolidated balance sheet as of December 31, 1999.

     In March 1999, the Company entered into an equipment lease facility with
  a preferred stockholder under which the Company leased $137,300 of
  equipment for a 24-month term.

     In August 1999, the Company entered into a strategic agreement with
  NorthPoint. Under the terms of the strategic agreement, NorthPoint has
  agreed to use certain of the Company's domestic IBX centers and install
  their operational nodes in such centers. In exchange, the Company granted
  NorthPoint a warrant to purchase 338,145 shares of the Company's common
  stock at $0.53 per share. The NorthPoint Warrant was earned upon execution
  of the strategic agreement as NorthPoint's performance commitment was
  complete. The NorthPoint Warrant is immediately exercisable and expires
  five years from date of grant. The NorthPoint Warrant was valued at
  $1,507,800 using the Black-Scholes option-pricing model (see Note 5).

(10) Segment Information

     During the year ended December 31, 1999, the Company adopted the
  provisions of SFAS No. 131, Disclosures about Segments of an Enterprise and
  Related Information. SFAS No. 131 requires disclosures of selected segment-
  related financial information about products, major customers and
  geographic areas.

     The Company and its subsidiary are principally engaged in the design,
  build-out and operation of neutral IBX centers. All revenues result from
  the operation of these IBX centers. Accordingly, the Company considers
  itself to operate in a single segment for purposes of disclosure under SFAS
  No. 131. The Company's chief operating decision-maker evaluates
  performance, makes operating decisions and allocates resources based on
  financial data consistent with the presentation in the accompanying
  consolidated financial statements.

(11) Subsequent Events (unaudited)

     In January 2000, the Company's stockholders approved an amendment to the
  1998 Stock Plan increasing the aggregate number of common shares available
  for issuance over the term of the Plan by 3,750,000 to a total of
  12,012,810 shares.

     In January 2000, the Company's stockholders approved a three-for-two
  stock split of its common and preferred stock effective January 19, 2000.
  The Company amended and restated its Certificate of Incorporation to
  increase the authorized share capital to 132,000,000 shares of common stock
  and 68,000,000 shares of preferred stock, of which 32,000,000 has been
  designated as Series A and 36,000,000 as Series B, to give effect to the
  three-for-two stock split. The accompanying consolidated financial
  statements have been adjusted to reflect this stock split.

     In January 2000, the Company entered into an operating lease for its
  Dallas, Texas IBX center. The agreement is for a minimum of 10 years, with
  annual rent payments increasing from $1,131,000 to $1,357,200 over the
  lease term.

     In January 2000, the Company entered into an operating lease agreement
  for its new corporate headquarters facility in Mountain View, California.
  The agreement is for a minimum of seven years, with annual rent payments
  increasing from $1,662,600 to $2,103,800 over the lease term. In connection
  with the lease agreement, the Company granted the lessor a warrant to
  purchase up to 33,100 shares of the Company's common stock at $6.00 per
  share. The warrant is exercisable upon certain defined events occurring
  through May 28, 2000 and expire in 10 years from the date of grant. The
  warrant was valued at $185,700 using the Black-Scholes option pricing model
  and will be recorded as additional rent expense over the life of the lease.
  The following assumptions were used in determining the fair value of the
  warrant: deemed fair value per share of $6.55, dividend yield of 0%,
  expected volatility of 80%, risk-free interest rate of 6.0% and a
  contractual life of 10 years.

     In January 2000, the Company advanced an aggregate of $250,000 to an
  officer of the Company, which is evidenced by a promissory note. The
  proceeds of this loan were used to fund the purchase of a principal
  residence. The loan is due January 13, 2005, but is subject to certain
  events of acceleration, including an initial public offering of the
  Company's common stock. The loan is secured by a second deed of trust on
  the officer's residence and is non-interest bearing.

     In April 2000, the Company entered into a definitive agreement with a
  fiber carrier whereby the fiber carrier agreed to install high-bandwidth
  local connectivity services to a number of the Company's IBX centers in
  exchange for colocation space and related benefits in such IBX centers. In
  connection with this agreement, the Company granted the fiber carrier a
  warrant to purchase up to 540,000 shares of the Company's common stock at
  $4.00 per share. The warrant is immediately exercisable and expires five
  years from date of grant. Warrants for 140,000 shares are immediately
  vested and warrants for 400,000 shares are subject to repurchase at the
  original exercise price if certain performance commitments are not
  completed by a pre-determined date. The fiber carrier is not obligated to
  install high-bandwidth local connectivity services and, apart from
  forfeiting the relevant number of warrants and colocation space, will not
  be penalized for not installing. The warrant was valued at $5,371,800 using
  the Black-Scholes option-pricing model. The following assumptions were used
  in determining the fair value of the warrant: deemed fair market value per
  share of $11.82, dividend yield of 0%, expected volatility of 80%, risk-
  free

  interest rate of 6.56% and a contractual life of 5 years. Under the
  applicable guidelines in EITF 96-18, the underlying shares of common stock
  associated with this warrant subject to repurchase are revalued at each
  balance sheet date to reflect their current fair value until the
  performance commitment is complete. Any resulting increase in fair value of
  the warrants will be recorded as a leasehold improvement.

     In April 2000, the Company entered into an operating lease agreement for
  its Amsterdam, The Netherlands, IBX center. The Agreement is for a minimum
  of 15 years, with annual rent payments of 3,244,300 Dutch Guilders
  (approximately $1,336,300), adjusted annually according to the consumer
  price index (CPI).

     In April and May 2000, the Company granted additional stock options to
  employees to purchase 3,750,975 shares of common stock under the 1998 Stock
  Plan resulting in an additional deferred stock-based compensation charge of
  approximately $33.5 million.

     In May 2000, the Company amended and restated its Certificate of
  Incorporation to change the authorized share capital to 80,000,000 shares
  of common stock and 41,000,000 shares of preferred stock, of which
  20,000,000 has been designated as Series A, 16,000,000 has been designated
  as Series B and 7,000,000 has been designated as Series C.

     In May 2000, the Company's stockholders approved an amendment to the
  1998 Stock Plan increasing the aggregate number of common shares available
  for issuance over the term of the Plan by 3,000,000 to a total of
  15,012,810 shares.

     In May 2000, the Company completed the closing of the Series C
  convertible preferred stock financing. The Company raised approximately
  $77.8 million and issued 5,157,225 shares of Series C convertible preferred
  stock at $15.08 per share. The rights, preferences and privileges of the
  Series C convertible preferred stock are consistent with those outlined for
  Series A and B in Note 5 except as follows:

    . Dividends are payable at a rate of $1.21 per share

    . Holders have a liquidation preference of $15.08 per share plus all
      declared but unpaid dividends.

   On May 15, 2000, the board of directors agreed to waive the repurchase right
with respect to all of Albert M. Avery, IV's unvested shares.

   On May 16, 2000, Peter F. Van Camp, joined Equinix as chief executive
officer. His offer letter provides for the grant of an option to purchase
3,105,000 shares of common stock at the fair market value on the grant date
vesting monthly over four years. The agreement also provides for a no-interest
loan to Mr. Van Camp for up to $3,000,000 to purchase a primary residence. The
loan will be secured by Mr. Van Camp's primary residence and any shares of
stock that Mr. Van Camp obtains by exercising the options described above. The
agreement also details salary and caps the amount of relocation expenses. The
agreement further provides for 12 months of severance pay if Mr. Van Camp is
terminated by us for reasons other than cause or disability. The stock option
agreement with Mr. Van Camp provides that the Company's right to repurchase
unvested shares shall lapse upon certain changes in control of Equinix.

   On May 23, 2000 Equinix entered into an agreement to purchase approximately
79 acres of land in San Jose, California for approximately $82.0 million. The
sale is scheduled to close on June 15, 2000 pending certain closing conditions
being met. In addition, the Company executed a non-binding letter of intent
with a financing company whereby Equinix shall assign its rights under the
purchase agreement and shall enter into a long-term lease of the property. The
primary term of the lease will be 20 years with six renewal terms of ten years
each. The annual rent payments during years 1-5 shall be approximately
$9,475,500. Beginning the sixth lease year and every five years thereafter, the
rent payments will increase by the percentage increase in CPI but in no event
shall the annual cumulative increase exceed 3.5% per annum.

   Concurrent with the execution of the lease, the Company will be required to
post a letter of credit in the amount of $10 million. This letter of credit
shall increase to $35 million if the Company does not meet certain financing
targets. This security deposit shall be reduced on a pro rata basis based on
the status of construction activity. On the tenth anniversary and every tenth
year thereafter, Equinix shall have the right to repurchase the property at the
then fair market value, but no less than the original purchase price.

   There can be no assurance that the Company will secure this financing
arrangement. If Equinix is not able to secure this lease arrangement Equinix
will have the option to purchase the property directly. However, Equinix does
not intend to do so at this time.
