INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On March 16, 2018 we entered into a €225,000,000 unsecured subordinated revolving facility agreement (the “New Facility”) by and among InterXion Holding N.V. (the “Company”), ABN AMRO Bank N.V. and Bank of America Merrill Lynch International Limited as arrangers and original lenders thereunder and ABN AMRO Bank N.V. as agent.

The New Facility has an initial maturity date of December 31, 2018, with the Company having the option to extend the maturity date up to and including December 31, 2019 in accordance with the terms of the New Facility. The New Facility initially bears interest at a rate per annum equal to EURIBOR (subject to a 0% floor) plus a margin of 3.00% per annum from the date of the New Facility, subject to a margin ratchet pursuant to which the margin may increase thereafter on certain specified dates and subject to a maximum margin of 4.50% per annum.

The New Facility contains customary operating and restrictive covenants, subject to certain agreed exceptions, qualifications and thresholds as well as customary events of default (subject in certain cases to agreed grace periods, qualifications and thresholds).

The Company also received the requisite consents from lenders under its senior secured revolving facility agreement dated March 9, 2017 between, among others, the Company, ABN AMRO Bank N.V., Bank of America Merrill Lynch International Limited and Citigroup Global Markets Limited as arrangers thereunder in relation to entering into the New Facility.

The foregoing description of the New Facility is not intended to be a complete description of that agreement. The description is qualified in its entirety by the full text of that agreement which is attached as Exhibit 99.1 and incorporated by reference in this Report.
