基于上述内容，并在符合以下附加假设和条件的前提下，我们建议您：

When any supplemental indenture to be entered into in connection with the issuance of any Debt Securities of Equinix Europe 2 Finco has been duly authorized, executed and delivered by the Trustee, Equinix and Equinix Europe 2 Finco in accordance with the Base Indenture; the specific terms of a particular series of Debt Securities and the related Guarantees have been duly authorized and established in accordance with the Base Indenture; and such Debt Securities and the related Guarantees have been duly authorized, executed, authenticated, issued and delivered in accordance with the Base Indenture or any supplemental indenture and the applicable underwriting or other agreement against payment therefor, such Debt Securities will constitute valid and binding obligations of Equinix Europe 2 Finco and each of the related Guarantees will constitute valid and binding obligations of Equinix, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, provided that we express no opinion as to (w) the enforceability of any waiver of rights under any usury or stay law, (x) the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above or (y) the validity, legally binding effect or enforceability of any provision that permits holders to collect any portion of stated principal amount upon acceleration of the Debt Securities to the extent determined to constitute unearned interest.

当Equinix发行和出售发行股份（定义见股权分配协议），并根据股权分配协议的条款交付Equinix ，该等发行股份将有效发行，已缴足且无需评估。

当远期对冲股份（定义见股权分配协议）由相关远期卖方出售并在收到购买价后由相关远期卖方交付时，因此，根据股权分配协议的条款，该等远期对冲股份将有效发行、全额支付且不予评估。

In connection with the opinions expressed above, we have assumed that, at or prior to the time of the delivery of any such security, (i) the Board of Directors of Equinix and the Managers of Equinix Europe 2 Finco, as the case may be shall have duly established the terms of such security and duly authorized the issuance and sale of such security and such authorization shall not have been modified or rescinded; (ii) each of Equinix and Equinix Europe 2 Finco is, and shall remain, validly existing as an entity in good standing under the laws of the State of Delaware; (iii) the Post-Effective Amendment shall have become effective and such effectiveness shall not have been terminated or rescinded; (iv) the shares of Common Stock will not be issued or transferred in violation of any restriction or limitation contained in Article XI of Equinix’s Amended and Restated Certificate of Incorporation, as amended (the “Charter”); (v) upon the issuance of shares of Common Stock under the Equity Distribution Agreement, the total number of shares of Common Stock issued and outstanding will not exceed the total number of shares of Common Stock that Equinix is then authorized to issue under the Charter; (vi) the Base Indenture, any supplemental indenture, the Debt Securities, and the Equity Distribution Agreement are each valid, binding and enforceable agreements of each party thereto (other than as expressly covered above in respect of Equinix and Equinix Europe 2 Finco); and (vii) there shall not have occurred any change in law affecting the validity or enforceability of such security. We have also assumed that (i) the terms of any security whose terms are established subsequent to the date hereof and the issuance, execution, delivery and performance by Equinix or Equinix Europe 2 Finco of any such security (a) require no action by or in respect of, or filing with, any governmental body, agency or official and (b) do not contravene, or constitute a default under, any provision of applicable law or public policy or regulation or any judgment, injunction, order or decree or any agreement or other instrument binding upon Equinix or Equinix Europe 2 Finco.
