Frequently Asked Questions: Posted: 11/13/2009

1. After the acquisition closes, do employees retained by Equinix keep their Switch and Data accrued PTO balance?

The accrued PTO belongs to you as an employee. It would either carry over into your new “employer” or it would get paid out from Switch and Data.

2. Is the bonus payout guaranteed if the deal closes before the usual February payday? (i.e. if the deal closes on 1/30 and payment is normally 2/28, if people are terminated on 1/30 will they received their bonus?)

Yes, the bonus will be paid as per the guidelines of the Bonus plan. Given the example above, Switch and Data would pay the bonus prior to the close date and you must still be an employee of Switch and Data on payment date.

3. What should I do if I have employee requisitions in the system or need to replace someone that has left the company?

As we have stated, Switch and Data will continue to run the business as usual. During the past two weeks we have hired three new employees: Michael Nicosia (NAM in the Metro), Paul McLaughlin (technician in Waltham) and Anthony Hattel (technician in Sunnyvale). We also have approximately 6 more new hires to start in November. All new hires are being made aware of the merger transaction.

4. Keith’s letter of November 13 referenced milestones that have to be hit prior to the deal closing; what is a proxy and when it that expected?

A proxy is document prepared for shareholders with the latest information on the Company so the shareholders can make an informed vote. The Company prepares a proxy annually before the annual shareholder meeting. It is filed with the SEC, publicly posted on EDGAR, and delivered to all shareholders. Since the acquisition by merger must be approved by a vote of the shareholders, a proxy is being prepared to disclose all information associated with the acquisition by merger. It is difficult to predict exactly when it will be filed as a matter of public record because the SEC reviews and comments on the proxy. The goal is have the proxy complete, filed and delivered to shareholders sometime in December. The date of the shareholder meeting to vote on the acquisition by merger will be set for a date at least thirty (30) days after the filing and delivery of the proxy.
