2010 Incentive Plan

On February 11, 2010, the Compensation Committee of the Board of Directors of Equinix, Inc. (“Equinix”) approved the Equinix 2010 Incentive Plan (the “2010 Plan”) for eligible employees of Equinix, including executive officers, for the fiscal year ending December 31, 2010.

Under the 2010 Plan, an annual target bonus amount has been assigned to each executive officer and may be modified from time to time thereafter. The annual target bonus amounts under the 2010 Plan range from 55-100% of each executive’s base salary, depending on the executive’s position. The actual annual bonus is determined on the basis of Equinix’s performance against an EBITDA goal, as set forth in the Board of Directors-approved operating plan, adjusted from time to time throughout the plan year. The EBITDA goal will exclude the impact of one-time events affecting the operating plan, such as expansion projects or acquisitions not contemplated in the operating plan, and will exclude the impact of fluctuations in foreign currencies against the foreign currency rates applied in the operating plan. 100% of the 2010 Plan will be funded if the EBITDA target is met. For every 1% below operating plan for EBITDA, the bonus shall be reduced by 20%. No bonuses will be paid if EBITDA is 95% or less than the operating plan target. In addition, at its discretion the Compensation Committee may reduce or eliminate the actual award that otherwise would be payable should economic conditions warrant it.

Amendment to International Assignment Letter

On February 17, 2010, Equinix Operating Co., Inc. (“Op Co”), a wholly-owned subsidiary of Equinix, and Eric Schwartz, Equinix’s President, Equinix Europe, executed an amendment (the “Amendment”) to the international assignment letter dated April 15, 2008, as amended on December 19, 2008, by and between Op Co and Mr. Schwartz. The Amendment extends the term of the international assignment an additional two years, to August 1, 2012, on substantially the same terms and conditions.
