(“CyrusOne”) an aggregate number of common shares set forth on Exhibit A attached hereto, par value $.01 per share, of CyrusOne (the “Shares”) at the exercise price and on and subject to the terms of the Plan and your agreement to the terms, conditions and restrictions contained herein and subject to the achievement of certain performance-based vesting criteria (each, a “Performance Goal”) as set forth on Exhibit A (the “Options”).  Capitalized terms used in this performance option award agreement (this “Agreement”) that are not defined in this Agreement have the meanings as used or defined in the Plan.

2.   Exercise.  Upon the vesting of any Options as set forth in Section 3, 4, 5, 6 or 7 hereof, as applicable, such portion of the Options to the extent vested, may be exercised, in whole or in part (but for the purchase of whole Shares only), by delivery to CyrusOne of written notice of the number of Shares to be purchased. As soon as administratively practical after the receipt of the written notice and full payment applicable to the exercise of any of the Options, CyrusOne shall deliver to you (or such other person who is exercising the Option, as provided herein) a certificate or book-entry credit representing each acquired Share.  CyrusOne hereby agrees that at all times there shall be reserved for issuance and/or delivery upon exercise of any of the Options such number of Shares as shall be required for issuance or delivery upon exercise thereof.  You must pay for the Shares purchased pursuant to the exercise of the Options hereby granted using any one or more of the methods or any combination of the methods set forth in Section 19.2 of the Plan.  The exercise price of the Options and any applicable taxes required to be withheld upon the exercise of any of the Options must be paid in full at the time of the exercise, pursuant to Section 12 hereof.

3.   Performance Vesting and Exercise.

(a)           Except as otherwise provided in any Employment Agreement (as defined in Section 14 hereof) or determined by the Committee in its sole discretion or provided in Section 4, 5, 6 or 7 hereof, subject to the Committee’s determination that the applicable Performance Goal has been attained for the applicable Performance Evaluation Period (as defined in Exhibit A) at a Performance Level (as defined in Exhibit A) that permits vesting, as set forth in Section 3(b) below, on each Vesting Date (as defined in Exhibit A), the Options shall vest with respect to the number of Shares that corresponds to such Performance Level for such Vesting Date, as set forth on Exhibit A, and become exercisable.  In no event shall you have any rights to exercise any of the Options prior to the date such Options vest pursuant to this Agreement.  Your right to exercise any part or all of the Options shall expire ten years from the Award Date, unless sooner terminated or canceled as provided in this Agreement.

(b)           On each Determination Date (as defined below), the Committee shall determine whether the applicable Performance Goal has been attained, and the Performance Level at which it has been attained, for the applicable Performance Evaluation Period and shall provide notice to you of such determination as soon as reasonably practicable following such determination in accordance with Section 13 of this Agreement.  “Determination Date” means the date as soon as reasonably practicable following the completion of the applicable Performance Evaluation Period, as determined by the Committee, on which the Committee determines whether the applicable Performance Goal has been achieved.

(c)           For the avoidance of doubt, to the extent a number of Options vests and becomes exercisable pursuant to the terms of Section 4, 5, 6 or 7 of this Agreement, the number of Options that so vests shall include, but shall not be in addition to, any Options that previously vested and became exercisable pursuant to the terms of Section 3 of this Agreement.

4.   Termination of Restrictions Upon Death.  Except as otherwise provided in any Employment Agreement, in the event of your death while an Employee, then, effective as of the date of your death, the number of Options (rounded up to the nearest whole Share) that bears the same ratio to the target number of Shares subject to the Options (as set forth on Exhibit A) as the number of days from the Award Date through the date of your death bears to 1,096 shall vest (to the extent such Options have not earlier vested under the terms of this Agreement) and may be exercised in accordance with Section 2 hereof within one year after the date of your death (but not in any event later than the end of the day immediately preceding the tenth anniversary of the Award Date).  Any Options that remain unvested after the calculation described in the preceding sentence shall be forfeited to CyrusOne as of your date of death in accordance with the terms of Section 8 hereof.  Upon the vesting of certain Options under the first sentence of this Section 4 and subsequent exercise, the executor, administrator or other personal representative of your estate, or the trustee of any trust becoming entitled thereto by reason of your death, may transfer the applicable Shares to any person or persons entitled thereto under your will or under your trust or other instrument (or, in the absence of any will, under the laws of descent and distribution) governing the distribution of your estate in the event of your death.

5.   Termination of Restrictions Upon Disability.  Except as otherwise provided in any Employment Agreement, if, pursuant to the applicable disability provision of any Employment Agreement, you become disabled and as a result thereof cease to be an Employee under and pursuant to such provision or, if no such provision exists or you are not party to an Employment Agreement, you become disabled to such extent that you are unable to perform the usual duties of your job for a period of 12 consecutive weeks or more and, as the result thereof, the Committee approves the termination of your employment within the 12-month period following the first day of such 12 consecutive week period, then, effective as of the date you cease to be an Employee as described in this Section 5, the number of Options (rounded up to the nearest whole Share) that bears the same ratio to the target number of Shares subject to the Options (as set forth on Exhibit A) as the number of days from the Award Date through the date you cease to be an Employee bears to 1,096 shall vest (to the extent such Options have not earlier vested under the terms this Agreement) and may be exercised in accordance with Section 2 hereof within one year after the date of the termination of your employment due to disability (but not in any event later than the end of the day immediately preceding the tenth anniversary of the Award Date).  Any Options that remain unvested after the calculation described in the preceding sentence shall be forfeited to CyrusOne as of the date you cease to be an Employee in accordance with the terms of Section 8 hereof.

6.           Termination of Restrictions Upon Termination of Employment Other than for Death, Disability or Cause.  Except as otherwise provided in any Employment Agreement, if the Company terminates your employment other than by reason of your death or disability or other than for Cause, then, effective as of the date you cease to be an Employee as described in this Section 6, the number of Options (rounded up to the nearest whole Share) that bears the same ratio to the target number of Shares subject to the Options (as set forth on Exhibit A) as the number of days from the Award Date through the date you cease to be an Employee bears to 1,096 shall vest (to the extent such Shares have not earlier vested under the terms of this Agreement) and may be exercised in accordance with Section 2 hereof within one year after the date of the termination of your employment (but not in any event later than the end of the day immediately preceding the tenth anniversary of the Award Date). Any Options that remain unvested after the calculation described in the preceding sentence shall be forfeited to CyrusOne as of the date you cease to be an Employee in accordance with the terms of Section 8 hereof.  For purposes of this Agreement, “Cause” shall have the meaning set forth in any Employment Agreement, or, if you do not have an Employment Agreement, shall mean the occurrence of any one of the following: (i) your material dereliction of your duties, your gross negligence or substantial failure to perform your duties with the Company (other than any such failure resulting from incapacity due to physical or mental illness); (ii) your engaging in (A) misconduct that is materially injurious to the Company or (B) illegal conduct; (iii) your material breach of any written agreement by and between you and the Company; (iv) your violation of any material provision of the Company’s Code of Business Conduct and Ethics; or (v) your willful failure to cooperate in good faith with an investigation by any governmental authority.

7.           Termination of Restrictions Upon Change in Control.  If a Change in Control occurs, then, except as otherwise provided in any Employment Agreement, this award will be treated as provided in Section 17 of the Plan, provided, however, that, subject to the terms of any Employment Agreement and notwithstanding any other provision of this Agreement to the contrary, in the event that within twelve months following a Change in Control your employment is terminated by the Company other than for Cause,  then, effective as of the date of such termination, the number of Options (rounded up to the nearest whole Share) that bears the same ratio to the target number of Shares subject to the Options (as set forth on Exhibit A) as the number of days from the Award Date through the date you cease to be an Employee bears to 1,096 shall vest (to the extent such Shares have not earlier vested under the terms of this Agreement) and may be exercised in accordance with Section 2 hereof within one year after the date of the termination of your employment (but not in any event later than the end of the day immediately preceding the tenth anniversary of the Award Date).

8.           Forfeiture.  Except as otherwise determined by the Committee or provided in Sections 3, 4, 5, 6 and 7 hereof or any Employment Agreement, any Options that remain unvested on the date you cease to be an Employee shall be forfeited to CyrusOne as of such date and, upon such forfeiture, all of your rights in respect of such Options shall cease automatically and without further action by CyrusOne or you.

9.           Employment.  For purposes of this Agreement, you shall be deemed to be an “Employee” while, and only while, you are in the employ of the Company and considered to be employed under the policies and procedures (including the payroll and withholding procedures) of the Company.  In this regard, the granting of this Agreement does not constitute a contract of employment and does not give you the legal right to be continued as an Employee.

10.         Matters Relating to Certificates.  On or following the date of this Agreement, any Shares issued to you upon the exercise of the Options in accordance with and subject to this Agreement shall be evidenced in such manner as CyrusOne shall determine.

11.         Interpretation.  You acknowledge that the Committee has the authority to construe and interpret the terms of the Plan and this Agreement if and when any questions of meaning arises under the Plan or this Agreement, and any such construction or interpretation shall be binding on you, your heirs, executors, administrators, personal representatives and any other persons having or claiming to have an interest in the Options.

12.         Withholding.  In the event that the award and receipt of the Options, the vesting or exercise of any Options, the payment of dividends after the exercise of any Options or any other event results in your realization of income or wages which for federal, state and/or local income or other employment tax purposes is, in the opinion of the Company, subject to withholding of tax by the Company, you shall pay to the Company an amount equal to the withholding tax amount that the Company determines applies with respect to such event or make arrangements satisfactory to the Company regarding the payment of such tax, which arrangements may include your agreement to surrender Shares issued or delivered upon the exercise of Options that have vested.  Otherwise, the Company may, at its discretion and to the extent it determines is necessary to pay such withholding tax amount, withhold any such withholding tax amount from your salary, any Shares issued or delivered upon the exercise of Options that have vested or any other compensation payable to you.

13.         Notices.  All notices and other communications to be given hereunder shall be in writing and shall be deemed to have been duly given when delivered personally or when deposited in the United States mail, first class postage prepaid, and addressed as follows:

14.         Effect of Employment Agreement.  Notwithstanding any of the terms of the foregoing sections of this Agreement, if the provisions of a written employment agreement between you and the Company (any such agreement, an “Employment Agreement”) would require that any Options will vest or be exercisable on a date that occurs on or before the date the Options would have vested, become exercisable or been forfeited, in each case, under the terms of the foregoing sections of this Agreement, or would require that you be deemed to be employed by the Company until a date later than the actual date on which your employment terminates for purposes of determining the extent to which and the date on which the Options would vest, become exercisable or be forfeited, then such Employment Agreement provisions shall control (and shall be deemed an amendment to this Agreement and incorporated herein by reference), provided, however that notwithstanding any provision of this Agreement to the contrary, all Options shall automatically expire on the tenth anniversary of the Award Date.  In the event of any conflict between the terms of the Plan, on the one hand, and the terms of this Agreement or any Employment Agreement, on the other hand, the terms of the Plan shall govern.  In the event of any conflict between the terms of this Agreement and the terms of any Employment Agreement, the terms of such Employment Agreement shall govern.

(c)           The Committee may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate this Agreement prospectively or retroactively; provided, however, that any such waiver, amendment, alteration, suspension, discontinuance, cancelation or termination that would materially and adversely impair your rights hereunder shall not to that extent be effective without your consent (it being understood, notwithstanding the foregoing proviso, that this Agreement and the Shares shall be subject to the provisions of Sections 17 and 18 of the Plan).

(d)           All disputes, controversies and claims arising between you and CyrusOne concerning the subject matter of this Agreement or the Plan shall be settled by arbitration in accordance with the rules and procedures of the American Arbitration Association in effect at the time that the arbitration begins, to the extent not inconsistent with this Agreement or the Plan.  The location of the arbitration shall be Dallas, Texas or such other place as the parties to the dispute may mutually agree.  In rendering any award or ruling, the arbitrator or arbitrators shall determine the rights and obligations of the parties according to the substantive and procedural laws of the State of Texas.  The arbitration shall be conducted by an arbitrator selected in accordance with the aforesaid arbitration procedures.  Any arbitration pursuant to this Section 15(d) shall be final and binding on the parties, and judgment upon any award rendered in such arbitration may be entered in any court, Federal or state, having jurisdiction.  The parties to any dispute shall each pay their own costs and expenses (including arbitration fees and attorneys’ fees) incurred in connection with arbitration proceedings and the fees of the arbitrator shall be paid in equal amounts by the parties.  Nothing in this Section 15(d) shall preclude you or CyrusOne from seeking temporary injunctive relief from any Federal or state court located within the State of Texas in connection with or as a supplement to an arbitration hereunder.

(e)           You hereby acknowledge that (i) the business of CyrusOne, CyrusOne LP, CyrusOne LLC and each of their respective subsidiaries (the “CyrusOne Group”) in which you will be principally engaged is investing in and operating data centers throughout the United States and internationally, (ii) in the course of your employment with any member or members of the CyrusOne Group, you shall be entrusted with or obtain access to information proprietary to members of the CyrusOne Group and have access to and the benefit of goodwill belonging to the CyrusOne Group, (iii) you must not use the proprietary information or goodwill for the benefit of any entity except for the CyrusOne Group, (iv) this Section 15(e) is essential to protect the legitimate business and goodwill of the CyrusOne Group, does not impose an undue hardship on your and will not prevent you from engaging in gainful employment and (v) the Board would not have granted you this award but for the covenants and agreements set forth in this Section 15(e).  Therefore, ancillary to the otherwise enforceable agreements set forth in this Agreement, you hereby agree that at all times during the Term (as herein defined) and the Restricted Period (as herein defined), if applicable, you will not accept employment or engage or participate in any business activity (whether as a principal, partner, joint venturer, agent, employee, salesperson, consultant, independent contractor, director, officer or otherwise) with or as a Competitor (as herein defined) of the CyrusOne Group without the prior written consent of CyrusOne, which would involve you:

(A)           providing, selling or attempting to sell, or assisting in the sale or attempted sale of, any services or products competitive with or similar to those services or products with which you had any involvement, and/or regarding which you had any proprietary information, during your employment with any member or members of the CyrusOne Group (including any products or services being researched or developed by the CyrusOne Group during your employment with any member or members of the CyrusOne Group); or
