10

To the Contributor’s knowledge, except as set forth onSchedule 4.14, there are no environmental conditions existing at, on, under, upon or affecting the Properties any portion thereof that would reasonably be likely to result in any claim, liability or obligation under any Environmental Laws or Environmental Permit or any claim by any third party that would have a Material Adverse Effect.

Section 4.17. INVESTMENT. The Contributor acknowledges that the offering and issuance of the OP Units to be acquired pursuant to this Agreement are intended to be exempt from registration under the Securities Act and that the Operating Partnership’s reliance on such exemptions is predicated in part on the accuracy and completeness of the representations and warranties of the Contributor contained herein. In furtherance thereof, the Contributor represents and warrants to the Operating Partnership as follows:

(a) The Contributor is an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act).

(b) The Contributor is acquiring the OP Units solely for its own account for the purpose of investment and not as a nominee or agent for any other Person and not with a view to, or for offer or sale in connection with, any distribution of any thereof in violation of the securities Law.

(c) The Contributor is knowledgeable, sophisticated and experienced in business and financial matters; the Contributor has previously invested in securities similar to the OP Units and fully understands the limitations on transfer imposed by the federal securities Law. The Contributor is able to bear the economic risk of holding the OP Units for an indefinite period and is able to afford the complete loss of its investment in the OP Units; the Contributor has received and reviewed all information and documents about or pertaining to the Operating Partnership and the business and prospects of the Operating Partnership and the issuance of the OP Units as the Contributor deems necessary or desirable, and has been given the opportunity to obtain any additional information or documents and to ask questions and receive answers about such information and documents, the Operating Partnership and the business and prospects of the Operating Partnership which the Contributor deems necessary or desirable to evaluate the merits and risks related to its investment in the OP Units; and the Contributor understands and has taken cognizance of all risk factors related to the purchase of the OP Units. The Contributor is relying upon its own independent analysis and assessment (including with respect to taxes), and the advice of the Contributor’s advisors (including tax advisors), and not upon that of the Operating Partnership or any of the Operating Partnership’s Affiliates, for purposes of evaluating, entering into, and consummating the transactions contemplated hereby.

(d) The Contributor acknowledges that the OP Units have not been registered under the Securities Act and, therefore, may not be sold unless registered under the Securities Act or an exemption from registration is available.

Section 4.18. NO OTHER REPRESENTATIONS OR WARRANTIES. Other than the representations and warranties expressly set forth in this Article IV, the Contributor shall not be deemed to have made any other representation or warranty in connection with this Agreement or the transactions contemplated hereby.

ARTICLE V

INDEMNIFICATION

Section 5.01. GENERAL INDEMNIFICATION. From and after the Closing Date, each party hereto (each of which is an “Indemnifying Party”) shall indemnify and hold harmless the other party and its Affiliates (each of which is an “Indemnified Party”) from and against any and all charges, complaints, claims, actions, causes of action, losses, damages, liabilities and expenses of any nature whatsoever, including amounts paid in settlement, reasonable attorneys’ fees, costs of investigation, costs of investigative judicial or administrative proceedings or appeals therefrom and costs of attachment or similar bonds (collectively, “Losses”) arising out of or relating to, asserted against, imposed upon or incurred by the Indemnified Party in connection with or as a result of any breach of a representation, warranty or covenant of the Indemnifying Party contained in this Agreement or in any schedule, exhibit, certificate or affidavit or any other agreement, document or instrument delivered by the Indemnifying Party pursuant to this Agreement;provided,however, that: (i) the Operating Partnership shall not have any obligation under this Article to indemnify any Indemnified Party against any Losses to the extent that such Losses arise by virtue of (A) any diminution in value of the OP Units, (B) the Contributor’s breach of this Agreement, gross negligence, wilful misconduct or fraud or (C) CyrusOne LLC’s operation of its business or the ownership and operation of its assets outside of the ordinary course of business prior to the Closing Date; and (ii) the Contributor shall not have any obligation under this Article to indemnify any Indemnified Party against any Losses to the extent that such Losses arise by virtue of (A) any diminution in value of the Properties, (B) the Operating Partnership’s breach of this Agreement, gross negligence, wilful misconduct or fraud or (C) the Operating Partnership’s operation of its business or the ownership and operation of its assets outside of the ordinary course of business prior to the Closing Date; and

Section 5.02. NOTICE OF CLAIMS. At the time when any Indemnified Party learns of any potential claim that is subject to indemnification pursuant to the terms of this Agreement (a “Claim”) against the Indemnifying Party it will promptly give written notice (a “Claim Notice”) to the Indemnifying Party;provided that failure to do so shall not prevent recovery under this Agreement, except to the extent that the Indemnifying Party shall have been materially prejudiced by such failure. Each Claim Notice shall describe in reasonable detail the facts known to such Indemnified Party giving rise to such Claim, and the amount or good faith estimate of the amount of Losses arising therefrom. Unless prohibited by Law, such Indemnified Party shall deliver to the Indemnifying Party, promptly after such Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by such Indemnified Party relating to claims asserted by third parties (“Third Party Claims”). Any Indemnified Party may at its option demand indemnity under this Article V as soon as a Claim has been threatened by a third party, regardless of whether an actual Loss has been suffered, so long as such Indemnified Party shall in good faith determine that such claim is not frivolous and that such Indemnified Party may be liable for, or otherwise incur, a Loss as a result thereof.

Section 5.03. THIRD PARTY CLAIMS. The Indemnifying Party shall be entitled, at its own expense, to assume and control the defense of any Claims based on Third Party Claims, through counsel chosen by the Indemnifying Party and reasonably acceptable to such Indemnified Party (or any person authorized by such Indemnified Party to act on its behalf), if it

13

gives written notice of its intention to do so to such Indemnified Party within 30 days of the receipt of the applicable Claim Notice;provided,however, that such Indemnified Party may at all times participate in such defense at its expense. Without limiting the foregoing, in the event that the Indemnifying Party exercises the right to undertake any such defense against a Third Party Claim, such Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party (unless prohibited by Law), at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in such Indemnified Party’s possession or under such Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. No compromise or settlement of such Third Party Claim may be effected by either such Indemnified Party, on the one hand, or the Indemnifying Party, on the other hand, without the other’s consent (which consent shall not be unreasonably withheld, conditioned or delayed) unless (i) there is no finding or admission of any violation of Law and no effect on any other claims that may be made against such other party and (ii) each Indemnified Party that is party to such claim is released from all liability with respect to such claim.

Section 5.04. EXPIRATION.

(a) Subject to the limitations set forth in this Agreement, all representations, warranties, covenants and agreements (including those relating to indemnification in Section 5.01) made herein shall survive the Closing.

(b) Unless otherwise specified in this Agreement, all representations, warranties and covenants of the Indemnifying Party contained in this Agreement shall survive until twelve months after the Closing Date (the “Expiration Date”). If written notice of a claim in accordance with the provisions of this Article V has been given prior to the Expiration Date, then the relevant representation, warranty and covenant shall survive, but only with respect to such specific claim, until such claim has been finally resolved. Any claim for indemnification not so asserted in writing by the Expiration Date may not thereafter be asserted and shall forever be waived.

Section 5.05. LIMITATIONS ON AMOUNTS.

(a) Except as provided in subparagraph (b) below, the Contributor shall not have any liability under Section 5.01 for any Losses hereunder (i) unless and until the aggregate total amount of all such Losses for which the Contributor would, but for this provision, be liable exceeds, on a cumulative basis, one percent (1%) of the aggregate fair market value as of the Closing Date of the OP Units issued to the Contributor on the Closing Date (the “OP Value”), and then only to the extent of such excess, (ii) in excess of, on a cumulative basis, ten percent (10%) of the fair market value as of the Closing Date of the OP Units issued to the Contributor in respect of any Property, to the extent such Losses are directly related to or arise out of such Property and (iii) in excess of, on a cumulative basis, ten percent (10%) of the OP Value.

(b) The limitations in subparagraph (a) above shall not apply to any Losses resulting from breach of Section 4.04 with respect to a specific Property unless and until such time as the Operating Partnership (or a Subsidiary of the Operating Partnership)

14

obtains an endorsement providing the Operating Partnership with the benefit of the existing title insurance policy held by CBI or one of its Subsidiaries with respect to such Property, if any, or a new title insurance policy for the benefit of the Operating Partnership (or a Subsidiary of the Operating Partnership) in the same amount as the lenders’ title insurance policy required to be obtained under the CyrusOne Credit Agreement.

Section 5.06. EXCLUSIVE REMEDY. In furtherance of the foregoing, the Indemnified Party hereby waives, as of the Closing, to the fullest extent permitted under applicable Law, any and all rights, claims and causes of action (other than claims of, or causes of action arising from, fraud) it may have against the Indemnifying Party arising under or based upon any federal, state, local or foreign Law, other than the right to seek indemnity pursuant to this Article V. The foregoing sentence shall not limit the Indemnified Party’s right to specific performance or injunctive relief in connection with the breach by the Indemnifying Party of the provisions of this Agreement.

Section 5.07. TAX TREATMENT. All indemnity payments made hereunder shall be treated as adjustments to the consideration paid hereunder for United States federal income tax purposes.
