The subpoena requests documents relating to Equinix's stock option grants and practices. Equinix also reported that it has been notified that a shareholder derivative complaint was filed in the Superior Court of the State of California, County of San Mateo on June 29, 2006. The complaint against certain current and former officers and directors alleges that since 2000 stock option grants to certain employees were awarded with exercise prices that were lower than the market price on the actual grant dates and resulted in breaches of fiduciary duties with respect to Equinix's historic stock option granting practices. Equinix may be subject to other lawsuits from private plaintiffs concerning this subject area, and Equinix does not currently expect to file further current reports on Form 8-K describing such additional lawsuits.
