Dear Karl: 
 Equinix Operating Company, Inc. (“Equinix”)
is pleased to offer you employment on the following terms, contingent upon completion of a background investigation, satisfactory reference checks, and approval of the Compensation Committee of the Board of Directors of Equinix, Inc. 

1. Position. You will serve in a full-time capacity as President, Americas, with a primary work location at Equinix’s offices in Denver, Colorado,
and will report to Steve Smith, CEO & President. By signing this letter agreement, you represent and warrant to Equinix that you are under no contractual commitments inconsistent with your future obligations to Equinix. 

2. Salary. You will be paid a salary at the annual rate of $400,000, which will be paid on a bi-weekly basis in accordance with Equinix’s standard
payroll practices for salaried employees. This salary will be subject to adjustment from time to time pursuant to Equinix’s employee compensation policies then in effect. 

3. Restricted Stock Unit Award. Upon commencement of employment, you will be granted 12,000 restricted stock units (RSUs) of common stock of Equinix,
Inc. under the terms and conditions of the applicable equity award plan and your award agreement. Subject to your continued service through each vesting date, the award will vest over three years, with 16.667% of the RSUs vesting on March 1,
2014 and an additional 16.667% of the RSUs vesting on each September 1st and March 1st thereafter until fully vested. The award shall
provide for acceleration of 50% of the unvested RSUs in the event you are subject to a qualifying termination within 12 months after a change in control (as such terms are defined in the award agreement). Each RSU represents an unfunded right to
receive one share of Equinix, Inc. common stock upon vesting, provided you remain in active service through the vesting date. 
 4. Company-wide
Bonus. You will be eligible to participate in Equinix’s 2014 Annual Incentive Plan. Under the plan, you will be eligible to receive a bonus of up to 65% of your base salary, based upon Equinix’s financial

401(k) plan will be mailed to your home address from our 401(k) provider, Fidelity Investments, following your start date. Each payroll, Equinix will contribute 50 cents on every dollar up to the first 6% of your compensation that you defer

 6.
Health Benefits. You and your dependents will be entitled to participate in the Company’s medical and dental benefit plans in accordance with their terms.

any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company. While you render services to Equinix, you also will not assist any person or organization in
competing with Equinix, in preparing to compete with Equinix or in hiring any employees of Equinix. 
 12. Withholding Taxes. All forms of
compensation referred to in this letter are subject to reduction to reflect applicable withholding and payroll taxes.
