Item 1.01. Entry Into A Material Definitive Agreement.

     On February 3, 2006,  Equinix  Operating Co., Inc., a Delaware  Corporation
("Equinix") entered into a definitive purchase and sale agreement  ("Agreement")
with Amalgamated Bank of Chicago,  F/K/A Amalgamated Trust and Savings Bank, not
personally  but as Trustee  ("Seller").  The  Agreement  governs the purchase by
Equinix of a vacant 228,000 square foot standalone  office/warehouse  complex on
approx. 8 acres,  located in Elk Grove Village,  IL. The Agreement is subject to
various conditions,  including the satisfactory completion by Equinix of its due
diligence  review  of all  matters  regarding  the  property.  Equinix  posted a
refundable  deposit upon entering  into the Agreement and has an extendable  due
diligence period within which Equinix may cancel the Agreement for any reason or
no reason at all. The deposit will be applied against the $9.75 million purchase
price, which will be paid in cash at closing.  There is no material relationship
between Equinix and Seller.

     On February 8, 2006, the Company issued a press release  announcing the Elk
Grove Village property Agreement,  a copy of which is attached hereto as Exhibit
