At any time prior to May 15, 2022, Equinix may also redeem all or a part of the notes at a redemption price equal to 100% of the principal amount of notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the date of redemption (the “Redemption Date”), subject to the rights of Holders of record of notes on the relevant record date to receive interest due on the relevant interest payment date.

(1) 1.0% of the principal amount of the note; and

(2) the excess of:

(a) the present value at such Redemption Date of (i) the redemption price of the note at May 15, 2022 (such redemption price being set forth in the table appearing above under the caption “Optional Redemption”), plus (ii) all required interest payments due on the note through May 15, 2022 (excluding accrued but unpaid interest, if any, to, but not including, the Redemption Date), computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over

(b) the principal amount of the note, if greater.

“Treasury Rate” means, as of any Redemption Date, the weekly average rounded to the nearest 1/100th of a percentage point (for the most recently completed week for which such information is available as of the date that is two business days prior to such Redemption Date) of the yield to maturity of United States Treasury securities with a constant maturity (as compiled and published in Federal Reserve Statistical Release H.15 with respect to each applicable day during such week (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the Redemption Date to May 15, 2022; provided, however, that if the period from the Redemption Date to May 15, 2022 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

Listing: None

Trade Date: March 8, 2017

Settlement Date: It is expected that delivery of the notes will be made against payment therefor on or about March 22, 2017, which is the tenth business day following the date of pricing of the notes (such settlement cycle being referred to as “T+10”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing or the next succeeding six business days will be required, by virtue of the fact that the notes initially will settle in T+10, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.
