SUMMARY This summary may not contain all of the information that may be important to you. You should read the entire prospectus, including the section entitled "Risk Factors" beginning on page 8 and the financial data and related notes, before deciding whether to tender your initial notes in the exchange offer. 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 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. Equinix is located at 901 Marshall Street, Redwood City, California 94063. Our phone number is (650) 298-0400. 1

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 The exchange offer is not conditioned upon Offer....................... 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. 2

These documents should only be sent to the exchange agent. Questions regarding how to tender initial notes and requests for information should also be directed to the exchange agent. See "The Exchange Offer-- Procedures for Tendering Initial Notes." Expiration Date; The exchange offer will expire at 5:00 Withdrawal.................. p.m., New York City time on , 2000. We will accept for exchange any and all initial notes that are validly tendered in the exchange offer on or before 5:00 p.m., New York City time, on the expiration date. 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 expiration or termination of the exchange offer. The exchange notes issued in the exchange offer will be delivered promptly following the expiration date. See "The Exchange Offer--Expiration of the Exchange Offer" and "--Withdrawal of Tenders." Guaranteed Delivery If you wish to tender your initial notes Procedures.................. and (1) your initial notes are not immediately available or (2) you cannot deliver your initial notes together with the letter of transmittal to the exchange agent before the expiration date, you may tender your initial notes according to the guaranteed delivery procedures contained in the letter of transmittal. See "The Exchange Offer--Guaranteed Delivery Procedure." Acceptance of Initial Notes and Delivery of Exchange 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. The exchange notes issued in the exchange offer will be delivered promptly after acceptance of the initial notes. See "The Exchange Offer--Acceptance of Initial Notes for Exchange; Delivery of Exchange Notes." Tax Considerations.......... For U.S. federal income tax purposes, the exchange of initial notes for exchange 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-- Fees and Expenses." 3

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." 5

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. 7

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

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

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

. 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

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

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

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

. 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

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. 16

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. 17

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 as a result of being notified that they were no longer independent as a result of Cisco, Inc.'s investment in both KPMG 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. 18

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. 21

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

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

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

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

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 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. 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. 26

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. 27

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

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

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

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 31

We believe our IBX centers offer the following additional benefits to our customers: Type of Customer: Benefits: Content Providers, ASPs and . Direct interconnection with a choice of E-Commerce Companies multiple bandwidth providers, Internet service providers, and site and performance management companies. Choice gives participants the ability to decide which suppliers are the most cost-effective and provide the level of service they require. The benefits to content providers, ASPs and e-commerce companies include maximized Web presence, increased revenue streams, greater security and increased customer satisfaction .

Centralized market with access to dozens of potential customers Site and Performance Management. Direct interconnection with a choice of Companies multiple bandwidth providers and ISPs. Choice gives site and performance management companies the ability to decide which suppliers are the most cost-effective and provide the level of service they require 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. 32

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

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

$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

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. 36

Executive Compensation The following table sets forth compensation information for the period from June 1998 through December 31, 1999 paid by us for services by our chief executive officer during the fiscal year 1999 and our other highest-paid executive officers whose total annualized salary and bonus for such fiscal year exceeded $100,000: Summary Compensation Table Long-Term Compensation Annual Compensation Awards ------------------- ---------------------- Securities Name and Principal Position Salary($) Bonus($) Underlying Options(#) - --------------------------- --------- --------- ---------------------- Albert M. Avery, IV............... $ 178,020 0(1) President, Chief Executive Officer and Director Jay S. Adelson.................... $ 173,754 0(1) Chief Technology Officer and Director - -------- (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

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

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. 42

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: Month of Term of Advance Prepaid Percentage -------------------------------- ---------- 1-6 ....................................................... 8% 7-12....................................................... 7% 13-18....................................................... 6% 19-24....................................................... 5% 25-30....................................................... 4% 31-36....................................................... 3% 37-42....................................................... 2% 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

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%.

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.

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.

The fair value of these warrants, as determined using an 48

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.

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

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

. 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 , 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

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

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

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

. 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

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: By Mail: State Street Bank and Trust Company of California, N.A. c/o State Street Bank and Trust Company P.O. Box 778 Boston, MA 02101-0778 ATTN: Ralph Jones By Hand/Overnight Delivery: State Street Bank and Trust Company of California, N.A. c/o State Street Bank and Trust Company 2 Avenue de Layfayette Corporate Trust Window, 5th Floor Boston, MA 02111-1724 ATTN: Ralph Jones Facsimile Transmission: (617) 662-1452 Confirm by Telephone: (617) 662-1548 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

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." 58

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

. 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

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. Year Percentage ---- ---------- 2003.......................................................... 106.500% 2004.......................................................... 103.250% 2005 and thereafter........................................... 100.000% 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

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. 62

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

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

. 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

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

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

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

. 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. 70

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

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

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

. 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

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

. 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.

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

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

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. 91

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

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

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. 94

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. 95

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. 96

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.

EQUINIX, INC. 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 F-7

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

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. F-10

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. F-14

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.

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: December 31, ------------------------------------------ 1998 1999 March 31, 2000 -------------------- --------------------- -------------------- (unaudited) Weighted- Weighted- Weighted- average average average exercise exercise exercise Shares price Shares price Shares price --------- --------- ---------- --------- --------- --------- Outstanding at beginning of period.............. -- $ -- 2,074,050 $0.07 2,780,988 0.64 Granted................. 2,164,050 0.07 6,404,040 0.46 952,075 3.97 Forfeited............... -- -- (340,500) 0.06 (155,594) 0.07 Exercised...............

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: Period from June 22, 1998 Three (inception) months to Year ended ended December 31, December March 31, 1998 31, 1999 2000 ------------- ----------- ----------- (unaudited) Net loss: As reported...................... $(1,019,700) (20,790,600) (18,008,800) Pro forma........................ (1,021,600) (20,844,500) (18,117,400) 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. F-18

EQUINIX, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 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 F-19

EQUINIX, INC. 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: Warrants Exercise Series A preferred stock warrants outstanding price --------------------------------- ----------- -------- Comdisco Loan and Security Agreement Warrant......... 765,000 $ 0.67 Comdisco Master Lease Agreement Warrant.............. 30,000 1.67 Comdisco Master Lease Agreement Addendum Warrant..... 150,000 3.00 Venture Leasing Loan Agreement Warrant............... 300,000 3.00 --------- 1,245,000 ========= Warrants Exercise Common stock warrants outstanding price --------------------- ----------- -------- Senior Note Warrants................................. 3,376,500 $0.0067 NorthPoint Warrant................................... 338,145 0.53 WorldCom Warrant..................................... 675,000 0.67 Bechtel Warrant...................................... 352,500 1.00 --------- 4,742,145 ========= (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. F-20

EQUINIX, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The tax effect of temporary differences that give rise to significant portions of the deferred tax assets as of December 31, 1998 and December 31, 1999 is presented as follows: 1998 1999 -------- ---------- Deferred tax assets: Start-up expenses.................................... 316,000 2,551,000 Net operating loss................................... -- 3,134,000 Other................................................ 5,000 8,000 -------- ---------- Deferred tax assets................................ 321,000 5,693,000 Deferred tax liability: Depreciation and amortization........................

(320,000) (5,655,000) -------- ---------- -- -- ======== ========== 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: Year ending: 2000.......................................................... $ 4,949,700 2001.......................................................... 8,321,500 2002.......................................................... 8,578,700 2003.......................................................... 8,775,500 2004.......................................................... 9,045,300 Thereafter.................................................... 90,244,300 ------------ Total....................................................... $129,915,000 ============ F-21

EQUINIX, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 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. F-22

EQUINIX, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) As of December 31, 1998 and 1999, all of the Company's operations and assets are based in the United States. (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 F-23

EQUINIX, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 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 the Company 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. F-24

EQUINIX, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 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. F-25

PART II Information Not Required in Prospectus Item 20. Indemnification of Directors and Officers Section 145 of the Delaware General Corporation Law authorizes a court to award or a corporation's board of directors to grant indemnification to directors and officers in terms sufficiently broad to permit indemnification under limited circumstances for liabilities, including reimbursement for expenses incurred, arising under the Securities Act of 1933, as amended (the "Securities Act"). Article VII, Section 7.6 of our bylaws provides for mandatory indemnification of our directors and permissive indemnification of our officers and employees to the maximum extent permitted by the Delaware General Corporation Law. Our Certificate of Incorporation provides that our directors shall not be liable for monetary damages for breach of the directors' fiduciary duty as directors to our stockholders and us to the fullest extent permitted by the Delaware General Corporation Law. This provision in the Certificate of Incorporation does not eliminate the directors' fiduciary duty, and in appropriate circumstances, equitable remedies like injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to us for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for actions leading to improper personal benefit to the director, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision also does not affect a director's responsibilities under any other law, like the federal securities laws or state or federal environmental laws. We have entered into indemnification agreements with our officers and directors, a form of which is attached as Exhibit 10.5 and incorporated herein by reference. The indemnification agreements provide our officers and directors with further indemnification to the maximum extent permitted by the Delaware General Corporation Law. Item 21.

Item 22. Undertakings Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the Registrant in accordance with the provisions described in Item 20 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission this indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities, other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding, is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of this issue. The undersigned Registrant hereby undertakes that: (1) It will respond to requests for information that is incorporated by reference into the prospectus in accordance with Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed after the effective date of the registration statement through the date of responding to the request. (2) It will supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective. (3) It will file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (a) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (b) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission in accordance with Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; (c) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement. (4) For the purpose of determining any liability under the Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (5) It will remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. II-3

Exhibit 3.1 AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF EQUINIX, INC. (Pursuant to Sections 242 and 245 of the General Corporation Law of the State of Delaware) Equinix, Inc., a corporation organized and existing under and by virtue of the provisions of the General Corporation Law of the State of Delaware (the "General Corporation Law"), originally incorporated on June 22, 1998, under the name Quark Communications, Inc. DOES HEREBY CERTIFY: FIRST: That the name of this corporation is Equinix, Inc. SECOND: That the Board of Directors duly adopted resolutions proposing to amend and restate the Certificate of Incorporation of this corporation, declaring said amendment and restatement to be advisable and in the best interests of this corporation and its stockholders, and authorizing the appropriate officers of this corporation to solicit the consent of the stockholders therefor, which resolution setting forth the proposed amendment and restatement is as follows: RESOLVED, that the Certificate of Incorporation of this corporation be amended and restated in its entirety as follows: ARTICLE I The name of this corporation is Equinix, Inc. ARTICLE II The address of the registered office of this corporation in the State of Delaware is 15 E. North St., P.O. Box 899, in the City of Dover, County of Kent. The name of its registered agent at such address is Incorporating Services, Ltd. ARTICLE III The nature of the business or purposes to be conducted or promoted is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of Delaware. ARTICLE IV A. Classes of Stock. This corporation is authorized to issue two ---------------- classes of stock to be designated, respectively, "Common Stock" and "Preferred Stock." The total number of shares that this corporation is authorized to issue is one hundred twenty-three million (123,000,000) shares. Eighty million (80,000,000) shares shall be Common Stock and forty-

three million (43,000,000) shares shall be Preferred Stock, each with a par value of $0.001 per share. B. Rights, Preferences and Restrictions of Preferred Stock. The ------------------------------------------------------- Preferred Stock authorized by this Amended and Restated Certificate of Incorporation may be issued from time to time in one or more series. The rights, preferences, privileges, and restrictions granted to and imposed on the Series A Preferred Stock, which series shall consist of twenty million (20,000,000) shares (the "Series A Preferred Stock"), the Series B Preferred Stock, which series shall consist of sixteen million (16,000,000) shares (the "Series B Preferred Stock"), and the Series C Preferred Stock, which series shall consist of seven million (7,000,000) shares (the "Series C Preferred Stock"), are as set forth below in this Article IV(B). 1. Dividend Provisions. ------------------- (a) The holders of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock shall be entitled to receive dividends at the rate of $0.05 per share, $0.43 per share, and $1.21 per share (as adjusted for any stock dividends, combinations or splits with respect to such shares) per annum, respectively, payable out of funds legally available therefor. Such dividends shall be payable only when, as, and if declared by the Board of Directors and shall be noncumulative. (b) No dividends (other than those payable solely in the Common Stock of the corporation) shall be paid on any Common Stock of the corporation during any fiscal year of the corporation until dividends in the total amount of $0.05 per share, $0.43 per share, and $1.21 per share (as adjusted for any stock dividends, combinations or splits with respect to such shares) on the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock, respectively, shall have been paid or declared and set apart during that fiscal year and no dividends shall be paid on any share of Common Stock unless a dividend (including the amount of any dividends paid pursuant to the provisions of subsection (a) above) is paid with respect to all outstanding shares of Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock in an amount for each such share of Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock equal to or greater than the aggregate amount of such dividends for all shares of Common Stock into which each such share of Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock could then be converted. (c) In the event of a conversion of the Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock pursuant to Section 4 hereof, any accrued and unpaid dividends shall be paid at the election of the holder in cash or Common Stock at its then fair market value, as determined by the Board of Directors. 2. Liquidation Preference. ---------------------- (a) In the event of any liquidation, dissolution or winding up of this corporation, either voluntary or involuntary, the holders of Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of this corporation to the holders of Common Stock by reason of their ownership thereof, (A) in the case of the Series A Preferred Stock, an amount per share equal to the sum of (i) $0.67 for each outstanding share of 2

Series A Preferred Stock (the "Original Series A Issue Price"), and (ii) an amount equal to declared but unpaid dividends on such share (subject to adjustment of such fixed dollar amounts for any stock splits, stock dividends, combinations, recapitalizations or the like), (B) in the case of the Series B Preferred Stock, an amount per share equal to the sum of (i) $5.33 for each outstanding share of Series B Preferred Stock (the "Original Series B Issue Price"), and (ii) an amount equal to declared but unpaid dividends on such share (subject to adjustments of such fixed dollar amounts for any stock splits, stock dividends, combinations, recapitalizations or the like), and (C) in the case of the Series C Preferred Stock, an amount per share equal to the sum of (i) $15.08 for each outstanding share of Series C Preferred Stock (the "Original Series C Issue Price"), and (ii) an amount equal to declared but unpaid dividends on such share (subject to adjustments of such fixed dollar amounts for any stock splits, stock dividends, combinations, recapitalizations or the like). If upon the occurrence of such event, the assets and funds thus distributed among the holders of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock shall be insufficient to permit the payment to such holders of the full aforesaid preferential amounts, then, the entire assets and funds of this corporation legally available for distribution shall be distributed ratably among the holders of Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock in proportion to the full preferential amount each such holder is otherwise entitled to receive under this subsection (a). (b) Upon the completion of the distribution required by subsection (a) of this Section 2 all of the remaining assets of this corporation available for distribution to stockholders shall be distributed among the holders of Common Stock pro rata based on the number of shares of Common Stock held by each. (c) (i) For purposes of this Section 2, a liquidation, dissolution or winding up of this corporation shall be deemed to be occasioned by, or to include (unless the holders of at least a majority of the Preferred Stock then outstanding shall determine otherwise), (A) the acquisition of this corporation by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation) that results in the transfer of fifty percent (50%) or more of the outstanding voting power of this corporation; or (B) a sale of all or substantially all of the assets of this corporation. (ii) In any of such foregoing events, if the consideration received by this corporation is other than cash, its value will be deemed its fair market value. Any securities shall be valued as follows: (A) Securities not subject to investment letter or other similar restrictions on free marketability covered by (B) below: (1) If traded on a securities exchange or through the Nasdaq National Market, the value shall be deemed to be the average of the closing prices of the securities on such exchange or system over the thirty (30) day period ending three (3) days prior to the closing; 3

(2) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the thirty (30) day period ending three (3) days prior to the closing; and (3) If there is no active public market, the value shall be the fair market value thereof, as mutually determined by this corporation and the holders of at least a majority of the voting power of all then outstanding shares of Preferred Stock. (B) The method of valuation of securities subject to investment letter or other restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder's status as an affiliate or former affiliate) shall be to make an appropriate discount from the market value determined as above in (A) (1), (2) or (3) to reflect the approximate fair market value thereof, as mutually determined by this corporation and the holders of at least a majority of the voting power of all then outstanding shares of such Preferred Stock. (iii) In the event the requirements of this subsection 2(c) are not complied with, this corporation shall forthwith either: (A) cause such closing to be postponed until such time as the requirements of this Section 2 have been complied with; or (B) cancel such transaction, in which event the rights, preferences and privileges of the holders of the Preferred Stock shall revert to and be the same as such rights, preferences and privileges existing immediately prior to the date of the first notice referred to in subsection 2(c)(iv) hereof. (iv) This corporation shall give each holder of record of Preferred Stock written notice of such impending transaction not later than twenty (20) days prior to the stockholders' meeting called to approve such transaction, or twenty (20) days prior to the closing of such transaction, whichever is earlier, and shall also notify such holders in writing of the final approval of such transaction. The first of such notices shall describe the material terms and conditions of the impending transaction and the provisions of this Section 2, and this corporation shall thereafter give such holders prompt notice of any material changes. The transaction shall in no event take place sooner than twenty (20) days after this corporation has given the first notice provided for herein or sooner than ten (10) days after this corporation has given notice of any material changes provided for herein; provided, however, that such periods may be shortened upon the written consent of the holders of Preferred Stock that are entitled to such notice rights or similar notice rights and that represent at least a majority of the voting power of all then outstanding shares of such Preferred Stock. 3. Redemption. The Preferred Stock is not redeemable. ---------- 4. Conversion. The holders of the Preferred Stock shall have ---------- conversion rights as follows (the "Conversion Rights"): (a) Right to Convert. Each share of Series A Preferred Stock, Series B ---------------- Preferred Stock, and Series C Preferred Stock shall be convertible, at the option of the holder thereof, at any time after the date of issuance of such share, at the office of this corporation or 4

any transfer agent for such stock, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Original Issue Price for such series by the Conversion Price applicable to such share, determined as hereafter provided, in effect on the date the certificate is surrendered for conversion. The initial Conversion Price for shares of Series A Preferred Stock shall be the Original Series A Issue Price, the initial Conversion Price for shares of Series B Preferred Stock shall be the Original Series B Issue Price, and the initial Conversion Price for shares of Series C Preferred Stock shall be the Original Series C Issue Price, subject to adjustment as set forth in Section 4(d) hereof. (b) Automatic Conversion. Each share of Series A Preferred Stock, -------------------- Series B Preferred Stock, and Series C Preferred Stock shall automatically be converted into shares of Common Stock at the Conversion Price at the time in effect for such series immediately upon the earlier of (i) this corporation's sale of its Common Stock in a firm commitment underwritten public offering pursuant to a registration statement on Form S-1 or Form SB-2 under the Securities Act of 1933, as amended, provided that the aggregate gross offering price is at least $25,000,000 or (ii) upon vote of the holders of a majority of the then outstanding shares of Preferred Stock (which provision may be amended only by a majority vote of the holders of the Preferred Stock). (c) Mechanics of Conversion. Before any holder of Preferred Stock ----------------------- shall be entitled to convert the same into shares of Common Stock, he or she shall surrender the certificate or certificates therefor, duly endorsed, at the office of this corporation or of any transfer agent for the Preferred Stock, and shall give written notice to this corporation at its principal corporate office, of the election to convert the same and shall state therein the name or names in which the certificate or certificates for shares of Common Stock are to be issued. This corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Preferred Stock, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of such date. If the conversion is in connection with an underwritten offering of securities registered pursuant to the Securities Act of 1933, the conversion may, at the option of any holder tendering Preferred Stock for conversion, be conditioned upon the closing with the underwriters of the sale of securities pursuant to such offering, in which event the persons entitled to receive the Common Stock upon conversion of the Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately prior to the closing of such sale of securities. (d) Conversion Price Adjustments of Preferred Stock for Certain ----------------------------------------------------------- Splits and Combinations. The Conversion Price of the Series A Preferred Stock, - ----------------------- Series B Preferred Stock, and Series C Preferred Stock shall be subject to adjustment from time to time as follows: (i) (A) If this corporation shall issue, after the date upon which any shares of Series C Preferred Stock were first issued (the "Purchase Date"), any Additional Stock (as defined below) without consideration or for a consideration per share less than the Conversion Price for such series in effect immediately prior to the issuance of such Additional 5

Stock, the Conversion Price for such series in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this clause (i)) be adjusted to a price determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including shares of Common Stock deemed to be issued pursuant to subsection 4(d)(i)(E)(1) or (2)) plus the number of shares of Common Stock that the aggregate consideration received by this corporation for such issuance would purchase at such Conversion Price; and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including shares of Common Stock deemed to be issued pursuant to subsection 4(d)(i)(E)(1) or (2)) plus the number of shares of Additional Stock. (B) No adjustment of the Conversion Price for the Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock shall be made in an amount less than one cent per share, provided that any adjustments that are not required to be made by reason of this sentence shall be carried forward and shall be either taken into account in any subsequent adjustment made prior to three (3) years from the date of the event giving rise to the adjustment being carried forward, or shall be made at the end of three (3) years from the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in subsections (E)(3) and (E)(4), no adjustment of such Conversion Price pursuant to this subsection 4(d)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment. (C) In the case of the issuance of Common Stock for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses allowed, paid or incurred by this corporation for any underwriting or otherwise in connection with the issuance and sale thereof. (D) In the case of the issuance of the Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair value thereof as determined by the Board of Directors as determined in good faith irrespective of any accounting treatment. (E) In the case of the issuance (whether before, on or after the applicable Purchase Date) of options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock or options to purchase or rights to subscribe for such convertible or exchangeable securities, the following provisions shall apply for all purposes of this subsection 4(d)(i) and subsection 4(d)(ii): (1) The aggregate maximum number of shares of Common Stock deliverable upon exercise (assuming the satisfaction of any conditions to exercisability, including without limitation, the passage of time, but without taking into account potential antidilution adjustments) of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)), if any, received by this corporation upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights (without taking into account potential antidilution adjustments) for the Common Stock covered thereby. 6

(2) The aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange (assuming the satisfaction of any conditions to convertibility or exchangeability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) for, any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration, if any, received by this corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by this corporation (without taking into account potential antidilution adjustments) upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)). (3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to this corporation upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof (unless such options or rights or convertible or exchangeable securities were merely deemed to be included in the numerator and denominator for purposes of determining the number of shares of Common Stock outstanding for purposes of subsection 4(d)(i)(A)), the Conversion Price of the Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities. (4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price of the Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities (unless such options or rights were merely deemed to be included in the numerator and denominator for purposes of determining the number of shares of Common Stock outstanding for purposes of subsection 4(d)(i)(A)), shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities that remain in effect) actually issued upon the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities. (5) The number of shares of Common Stock deemed issued and the consideration deemed paid therefor pursuant to subsections 4(d)(i)(E)(1) and (2) shall be appropriately adjusted to reflect any change, termination or expiration of the type described in either subsection 4(d)(i)(E)(3) or (4). 7

(ii) "Additional Stock" shall mean any shares of Common Stock issued (or deemed to have been issued pursuant to subsection 4(d)(i)(E)) by this corporation after the Purchase Date other than: (A) Shares of Common Stock issuable or issued to employees, consultants, directors or vendors (if in transactions with primarily non-financing purposes) of this corporation directly or pursuant to a stock option plan or restricted stock plan approved by the Board of Directors of this corporation; (B) The issuance of stock, warrants or other securities or rights upon approval by the Company's Board of Directors (including the Series B Director) to persons or entities with which the Company has business relationships provided such issuances are for other than primarily equity financing purposes; (C) The issuance of securities pursuant to a bona fide, firmly underwritten public offering of shares of Common Stock, registered under the Act resulting in proceeds to the Company of at least $25,000,000 in the aggregate; (D) The issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities; or (E) The issuance of securities in connection with a bona fide business acquisition of or by the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise. (iii) In the event this corporation should at any time or from time to time after the Purchase Date fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock without a corresponding adjustment to the Conversion Price of the Preferred Stock, the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of Common Stock (hereinafter referred to as "Common Stock Equivalents") without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Price of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents. (iv) If the number of shares of Common Stock outstanding at any time after the Purchase Date is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Conversion Price for the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares. 8

(e) Other Distributions. In the event this corporation shall declare ------------------- a distribution payable in securities of other persons, evidences of indebtedness issued by this corporation or other persons, assets (excluding cash dividends) or options or rights not referred to in subsection 4(d)(i), then, in each such case for the purpose of this subsection 4(e), the holders of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of shares of Common Stock of this corporation into which their shares of Series A Preferred Stock, Series B Preferred Stock, and/or Series C Preferred Stock are convertible as of the record date fixed for the determination of the holders of Common Stock of this corporation entitled to receive such distribution. (f) Recapitalizations. If at any time or from time to time there ----------------- shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 4 or Section 2 provision shall be made so that the holders of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock shall thereafter be entitled to receive upon conversion of the Series A Preferred Stock, Series B Preferred Stock, and/or Series C Preferred Stock the number of shares of stock or other securities or property of the Corporation or otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 4 with respect to the rights of the holders of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock after the recapitalization to the end that the provisions of this Section 4 (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable. (g) No Impairment. This corporation will not, by amendment of its ------------- Amended and Restated Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by this corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock against impairment. (h) No Fractional Shares and Certificate as to Adjustments. ------------------------------------------------------ (i) No fractional shares shall be issued upon the conversion of any share or shares of the Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the total number of shares of Series A Preferred Stock, Series B Preferred Stock, and/or Series C Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. 9

(ii) Upon the occurrence of each adjustment or readjustment of the Conversion Price of Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock pursuant to this Section 4, this corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock a certificate executed by the Corporation's President or Chief Financial Officer setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. This corporation shall, upon the written request at any time of any holder of Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth (A) such adjustment and readjustment, (B) the Conversion Price for such series of Preferred Stock at the time in effect, and (C) the number of shares of Common Stock and the amount, if any, of other property that at the time would be received upon the conversion of a share of Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred Stock. (i) Notices of Record Date. In the event of any taking by this ---------------------- corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, this corporation shall mail to each holder of Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock, at least twenty (20) days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right. (j) Reservation of Stock Issuable Upon Conversion. This corporation --------------------------------------------- shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock, in addition to such other remedies as shall be available to the holder of such Preferred Stock, this corporation will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite shareholder approval of any necessary amendment to this Amended and Restated Certificate of Incorporation. (k) Notices.

9.1.2 In the event that it was agreed that sales tax will be charged on the rent, the lessee and the lessor explicitly declare that the starting point for determining the rent was that the lessee will continue to use the leased space or cause it to be used for purposes for at least the percentage determined by law or a minimum percentage to be determined at a later date for activities which entitle the lessee to deduct sales tax, in such a way that the parties can opt for taxed rent. 9.1.3 The lessee and lessor will make use of the possibility by virtue of Notification 45, decision of 24 March 1999, no. VB 99/571 to waive the right to submit a joint request to opt for rent subject to sales tax and to limit it to a statement to be filled in and signed by the lessee, which statement forms an integral part of the present lease. The stipulations of Article 5.3 of the lease are therefore hereby declared to be inapplicable. 9.1.4 The lessee will send a signed and completed statement to the lessor in accordance with a model to be made available by the lessor not later than on the date of signing this lease from which it appears that the lessee will use the leased space or have it used for purposes for which a right to make a complete or practically complete deduction of sales tax exists as laid down in Section 15 of the Wet op de Omzetbelasting 1968 (Sales Tax Act 1968). 9.1.5 The lessee hereby declares that its financial year runs from January 1 to December 31. 9.1.6.a If the decision to grant taxed rent should be cancelled because the lessee no longer uses the leased space or causes it to be used for activities which entitle it to deduct sales tax, the lessee will no longer owe the lessor or its successor(s) in title sales tax on the rent, but the lessee will owe the lessor or its successor(s) in title in addition to the rent exclusive of sales tax commencing on the date on which the decision to grant taxed rent has been cancelled by way of a separate payment such an amount that the latter is fully compensated for: I. The sales tax which the lessor or its successor(s) in title is no longer allowed to deduct as a result of the cancellation of the possibility to deduct sales tax from the operating costs of or from investments in the leased space. II. The sales tax which the lessor or its successor(s) in title has to pay to the tax authorities as a result of the cancellation of the possibility to deduct sales tax due to a recalculation of the taxed rent as referred to in Section 15, subsection 4 of the Wet op de Omzetbelasting 1968 or revision as referred to in Sections 11, 12 and 13 of the Uitvoeringsbeschikking Cmzetbelasting 1968 (Sales Tax (Implementation) Decree 1968). III. All other loss which the lessor or its successor(s) in title incurs as a result of the cancellation of the possibility to deduct sales tax. 9.1.6.b The financial loss incurred by the lessor or its successor(s) in title as a result of the cancellation of the option for taxed rent will be paid by the lessee to the lessor or its - -------------------------------------------------------------------------------- Initials lessor: Initials lessee:

successor(s) in title every time together with the periodic rent payments and will, with the exception of the loss as referred to under I in 9.1.6.a, if possible be equally divided by means of an annuity over the remaining periods of the current lease term, but will be due and payable in full and immediately by the lessee if the lease is terminated prematurely, for whatever reason. 9.1.7 The stipulation referred to in II under 9.1.6.a will not apply if at the time when the present lease is concluded the revision period for deducting sales tax already paid with respect to the leased space has expired. 9.1.8 The stipulations referred to under 9.1.6 also apply if at the time when the lease is concluded the lessee has not provided the lessor with a signed `Sales Tax statement' filled in and signed by the lessee, as referred to under 9.1.3. The stipulation of 15.2 of the General Conditions is consequently hereby declared to be inapplicable. 9.1.9 If a situation as referred to in 9.1.6 occurs, the lessor or its successor(s) in title will inform the lessee what amounts must be paid by the lessor or its successor(s) in title to the tax authorities and provide insight into the other losses as referred to in 9.1.6, with the exception of loss determined in advance as referred to in I under 9.1.6.a. The lessor or its successor(s) in title will give its cooperation if the lessee wishes to have the specification of this additional loss made by the lessor or its successor(s) in title checked by an independent registered accountant. The costs of this will be at the lessee's expense. 9.1.10 In the event that the use to which the lessee puts the leased space or causes it to be put is not complied with in accordance with the purposes referred to under 9.1.2, the lessee will inform the lessor or its successor(s) in title of this by means of a signed statement within four weeks of the end of the financial year concerned. The lessee will also send a copy of this statement to the Sales Tax Inspectorate within the same period of time. 9.1.11 If the lessee does not fulfill the obligation to provide information as referred to under 9.1.3 or under 9.1.9 and/or does not comply with the obligation of occupation as referred to under 9.1.12 or if it turns out in retrospect that its assumptions were incorrect, and it turns out in retrospect that the lessor or its successor(s) in title has wrongly charged sales tax on the rent, the lessee shall be in default, and the lessor or its successor(s) in title shall be entitled to recover the resulting financial loss from the lessee. This loss concerns the full sales tax still due by the lessor or its successor(s) in title to the tax authorities plus interest and any increases as well as additional costs and loss. The stipulations in this paragraph contain an arrangement for compensation in the event that the taxed rent ceases to be applicable with retroactive effect, in addition to the arrangement set out in 9.1.6. The additional loss which results for the lessor or its successor(s) in title from the retroactive effect, will be payable by the lessee immediately, in full and as a lump sum. The lessor or its successor(s) in title will give its cooperation if the lessee wants to have the specification of this additional loss made by the lessor or its successor(s) in title checked by an independent registered accountant. The costs of this will be at the lessee's expense. - -------------------------------------------------------------------------------- Initials lessor: Initials lessee:

9.1.12 The stipulations set out under 9.1.6, 9.1.8 and 9.1.10 will also apply if the lessor or its successor(s) in title is confronted with a loss after the termination of the lease, whether premature or not, due to the cancellation of the taxed rent agreed upon by the parties. This loss will then be payable by the lessee to the lessor or its successor(s) in title immediately, in full and as a lump sum. 9.1.13 Without prejudicing the other relevant stipulations in the lease, the lessee will in any event put the leased space into use or cause it to be put into use before the end of the financial year in which it started to lease the space with application of the right of opting for taxed rent. Payments 9.2 Payments by the lessee must be made by automatic transfer. Carrying out work in the leased space 9.3 The lessee is permitted to carry out fitting-out work from October 1, 2000 (based on the planning of the building work by Slavenburg's Bouwbedrijven) without rent being payable to the lessor. The lessee will ensure its fitting-out work will not cause any nuisance to the fitting-out work carried out by the lessor's (sub)contractor(s). In consultation with Maasstede Vastgoed Ontwikkeling and Slavenburg's Bouwbedrijven, the lessee will submit to the lessor the standards and specifications (together with drawings) of the fixtures and fittings to be installed in the leased space for its approval. The lessee will not be permitted to carry out work in or on the leased space before the lessor has granted its written permission for the proposed alterations. Lessor shall not unreasonably withhold its approval. Commencement date of the lease 9.4 The commencement date of the lease as mentioned in Article 3.1 and in accordance with the rent payment obligation of the lessee is a target date. The commencement of the lease will be 6 (six) months after the date in Article 9.3 mentioned "carrying out work in the leased space". When the "carrying out work in the leased space" moves in time, the commencement date of the lease will be so much earlier or later subject to a period of 6 (six) months. The commencement date is a goal date. If goal date is not met, the rent date is moved along accordingly to six (6) months from fitting-out date. Level of outfitting 9.5 The leased space will be delivered by the lessor in accordance with: a. the drawings WE250f, WE251d, WE252d, WE253c, WE254e, WE255f and WE256c, all dated March 22, 2000 of Group 5 Van Der Ven (project number 98p22) and; b. schedule of alterations Equinix dated April 14, 2000 to specification number 372-2 dated December 1, 1999. - -------------------------------------------------------------------------------- Initials lessor: Initials lessee:

Subletting and reletting 9.7 The lessee has the right to sublet the leased space or parts thereof to companies belonging to the same group, including parent, sister or subsidiary companies as that of the lessee in accordance with the definition of Section 2:24 (a) and (b) of the Netherlands Civil Code, and to affiliated companies with which the lessee maintains a business relationship.

Lessee has the right to transfer this lease to the mentioned affiliated companies prior the written approval of the lessor.
