Manager Specific:

Q. What should I be focusing on to help support my employees through the integration process?

A. Managers play an important leadership role in supporting the success of the integration. The first 100 days should be focused on maintaining a solid relationship with each of your direct reports. This will be the biggest factor in the likelihood of employee satisfaction and retention of top talent following the closing of the transaction.

Here are just a few questions to consider asking your employees during the first few weeks:

• Do you have any concerns?

• Is there any immediate support you need from me right now?

Q. How should I be communicating to my employees at this time?

A. As a manager, you will play a key communication role and will be critical in helping your employees successfully work through the transition/changes ahead. Schedule regular weekly meetings to continue to update your team and get feedback. You should be open to all questions and answer them as honestly as you can. Do not, however, try to answer what you do not know for certain. It’s OK to say “I don’t know” and follow up with the employee at a later date.

Customer Questions:

Until the transaction closes, which is expected early next year, we need to make sure that both companies continue to operate independently. All Switch and Data employees must support the customer individually and not collaborate on any customer engagements. The Customer Questions to follow address Business As Usual for today and until the transaction closes.

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 new 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. 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 vice 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.
