AND CONFIDENTIALITY AGREEMENT

THIS NON-COMPETITION, NON-SOLICITATION AND CONFIDENTIALITY AGREEMENT (this “Agreement”) is made and entered into as of the 18th day of October, 2007, by and between DUPONT FABROS TECHNOLOGY, INC., a Maryland corporation (the “Company”), and Hossein Fateh (“Executive”).

Background

The Company and Executive are parties to an employment agreement, dated as of October 18, 2007, pursuant to which Executive is entitled to certain compensation and benefits (the “Employment Agreement”). The Employment Agreement also provides that the Company and Executive shall enter into a non-competition agreement in form and substance reasonably satisfactory to the Company. The Company now wishes to enter into this Agreement with Executive in order to establish certain restrictive covenants on the part of Executive that the Company has determined are necessary and appropriate to protect the interests of the Company and its successors during and for a reasonable period of time after termination of the employment of Executive by the Company.

In consideration of the covenants and agreements set forth in the Employment Agreement and herein, the parties hereby agree as follows:
