The Deal Explained:

• On 10/21/09 Switch and Data and Equinix announced that they had entered a definitive agreement for Equinix to acquire Switch and Data.

• The deal allows Equinix and Switch and Data to accelerate their market momentum and global reach by gaining additional depth in the North American markets, with the combined company having a presence in 22 markets, and leveraging a combined global footprint and service delivery platform for both companies’ customers. The current data center supply and demand imbalance requires that both companies accelerate supply to satisfy global demand both organically and through strategic acquisition.

• The deal expands the number of networks that both companies’ customers can leverage for interconnection, and significantly enhances Switch and Data’s domestic footprint to include new supply in key markets such as Chicago and Los Angeles where capacity is constrained.

• Both companies have an extraordinary commitment to customer care to meet the need for increased performance in terms of reliability and network latency. This customer-driven approach requires continued investment in existing services and new markets which may be leveraged through an integrated global expansion plan. The deal is proof of both companies’ commitment to their customers’ need for more data center capacity and presence in more markets.

• In addition, the acquisition helps both companies’ customers respond to two broad market trends. The rapid growth of demand for online information is requiring companies to store and distribute larger volumes of latency sensitive assets and applications at the network edge, near local population centers. At the same time, the market compels companies to develop global aggregation and distribution strategies for their digital assets and applications. The transaction is expected to give Equinix customers broader access to local markets for their network edge deployments, and Switch and Data customers a comprehensive solution to their global data center needs.

• Both companies’ expansion plans can be accelerated for their customers to better leverage the joint inventory available and to provide an integrated set of worldwide services for future data center builds that can meet customers’ growing global needs for capacity, increasing power and more interconnection choices.

• Lastly, the combined company may provide significant benefits in terms of increased shareholder value through continued revenue and EBITDA growth and synergy opportunities that benefit customers and shareholders alike.

Customer Benefits:

• Global presence

• Continued focus on core business (no distractions of new offerings)

• Both companies are committed to overall customer experience

• Added investment capacity from Equinix

• More markets (both customer sets) to support data center expansion, network diversity and lower latency-sensitive applications

• High level of Equinix support/reliability, single support/process

Growth and Scale:

• Entry into new markets:

• Core colocation and interconnection markets: Atlanta, Denver, Miami, Seattle, and Toronto have always been targets for Equinix expansion to meet core internet growth requirements for Equinix’s customers

• In addition, the acquisition helps Equinix’s customers respond to two broad market trends through 16 new markets:

• Rapid demand growth for the distribution of latency sensitive applications and content at the network edge near local centers

• Developing global aggregation and distribution strategies for customers’ digital assets and applications that are driven by network centric applications for their customers e.g. wireless intelligent phones and their data centric applications

• Additional capacity in existing Equinix markets:

• NYC, Silicon Valley and Dallas (in particular)

• Access to additional inventory in existing markets, new builds underway

• Delay expansion capex in some cases

• Switch and Data sites offer opportunity for additional expansion

• Additional capacity in existing Switch and Data markets:

• Chicago and Los Angeles

• Eleven international markets in Europe and Asia-Pacific

• Access to additional inventory in existing markets, new builds underway

• Delay expansion capex in some cases

Strategic Fit:

• Focus on colocation (not management services or selling bandwidth) helps reduce integration risk

• Strong customer relationships

• Ecosystem development (Network & Content, Financial Services and Enterprise)

• Good cultural fit between companies

Answers to Customer Questions:

Q. What will be the impact to Switch and Data customers?

A. Until the deal closes, which is expected early next year, both companies will continue to operate independently. Sales forces, site operations and operational support services are required to support customers individually and not collaborate on any customer engagements.

Q. When can existing Switch and Data customers expand into the Equinix sites?

A. Until the deal closes, both companies will continue to operate independently. Longer term, Equinix and Switch and Data will be addressing integration plans.

Q. How do I go about getting information on specific space/power availability and pricing in the Equinix data centers?

A. Until the deal closes, both companies will continue to operate independently. Longer term, Equinix and Switch and Data will be addressing integration plans.

Q. If I am a customer of both Switch and Data and Equinix, which pricing platform can I expect to use moving forward?

A. Today, it’s business as usual. After the deal closes and upon contract renewal, we will work with you on a case by case basis. Since both entities will remain separate until the deal closes, we would ask that customers maintain the agreed upon confidentiality terms in your agreements.

Q. If I expand into an Equinix data center, will I still see a single bill from Switch and Data (or vice versa)?

A. Until the deal closes, both companies will continue to operate independently. As such, we do not have a timetable at this time on when integrated billing will be available. We will provide updates as the integration plan proceeds.

Q. Will the Equinix offerings be integrated into the existing back office systems of Switch and Data or visa versa (Billing, Customer Service, Equinix Customer Care Portal)?

A. We will be evaluating what functions will be fully integrated and communicate timeframes as they become available. We will be making the customer-facing initiatives, such as sales and support efforts, a priority of the overall integration plan with a goal of ensuring that all customers continue to receive the highest levels of customer service and satisfaction.

Q. What will be the impact to existing Switch and Data customers?

A. Equinix is not planning any material changes to the operations of Switch and Data given their quality service resulting in years of high customer satisfaction scores. Equinix will work closely with the Switch and Data team on any future expansion possibilities. In addition, Switch and Data customers will now have expansion opportunities with a seamless offering across the US, European and Asia-Pacific markets.
