ZAYO GROUP HOLDINGS, INC.

GRANT NOTICE FOR 2014 STOCK INCENTIVE PLAN

RESTRICTED STOCK UNIT AWARD

(Part B Awards)

The number of restricted stock units earned, if any, will be determined following the end of the Performance Period based on the Company’s stock price performance over the Performance Period.

The following table set forth the number of restricted stock units, expressed as a percentage of the target number of restricted stock units set forth in the Grant Notice, earned by the Participant based upon the Company’s stock price performance over the Performance Period (calculated in the manner set forth below):

Examples: The payout percentage increases by     % for every 1% increase in stock price performance above 20% and up to 30%. The payout percentage increases by     % for every 1% increase in stock price performance above 6% and up to 10%. There is no payout under the Award if stock price performance is at or below 6%.

For purposes of this Award and the table above, “stock price performance” shall be calculated as the percentage increase in the Company’s stock price from the beginning to the end of the Performance Period, adjusted for dividends paid during the Performance Period (assuming such dividends are reinvested in the Common Stock on the dividend payment date). For purposes of this calculation, the Company’s stock price at the beginning and end of the Performance Period shall be the average closing price of the Common Stock over the ten (10) trading day period ending on the date of determination.

The Committee must certify the results and the payout percentage prior to settlement of the Award. In addition, to the extent consistent Section 14 of the Plan, the Committee shall have the authority to make equitable adjustments in performance criteria set forth above (and/or the other terms and conditions of the Award) in the event of any acquisitions, divestures, spin-offs or other corporate restructurings that affect the Company.

STANDARD TERMS AND CONDITIONS FOR

RESTRICTED STOCK UNITS

(Part B Awards)

These Standard Terms and Conditions apply to the Award of restricted stock units granted pursuant to the Zayo Group Holdings, Inc. 2014 Stock Incentive Plan (the “Plan”), which are evidenced by a Grant Notice or an action of the Committee that specifically refers to these Standard Terms and Conditions and are designated as “Part B Awards”. In addition to these Standard Terms and Conditions, the restricted stock units shall be subject to the terms of the Plan, which are incorporated into these Standard Terms and Conditions by this reference. Capitalized terms not otherwise defined herein shall have the meaning set forth in the Plan.

Zayo Group Holdings, Inc. (the “Company”), has granted to the Participant named in the Grant Notice provided to said Participant herewith (the “Grant Notice”) an award of a number of restricted stock units (the “Award” or the “Restricted Stock Units”) with each Restricted Stock Unit representing the right to receive one share of the Company’s common stock, par value $0.001 (the “Common Stock”) specified in the Grant Notice. The Award is subject to the conditions set forth in the Grant Notice, these Standard Terms and Conditions, and the Plan, each as amended from time to time. For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

The number of Restricted Stock Units earned under the Award shall be determined according to the Grant Notice and Appendix A attached thereto.

The Award shall not be vested as of the Grant Date set forth in the Grant Notice and shall be forfeitable unless and until otherwise vested pursuant to the terms of the Grant Notice and these Standard Terms and Conditions. After the Grant Date, subject to termination or acceleration as provided in these Standard Terms and Conditions and the Plan, the Award shall become vested as described in the Grant Notice with respect to that number of earned Restricted Stock Units as determined pursuant to the Grant Notice and Appendix A attached thereto and certified by the Committee. Earned Restricted Stock Units that have vested and are no longer subject to forfeiture are referred to herein as “Vested RSUs.”

Notwithstanding anything contained in these Standard Terms and Conditions to the contrary, upon a Participant’s Termination of Employment prior to the Vesting Date set forth in the Grant Notice for any reason, the Award and all of the Restricted Stock Units subject thereto shall be forfeited and canceled as of the date of such Termination of Employment.

1

Each Vested RSU will be settled by the delivery of one share of Common Stock (subject to adjustment under Section 14 of the Plan) to the Participant or, in the event of the Participant’s death, to the Participant’s estate, heir or beneficiary, promptly following the Vesting Date (but in no event later than 30 days following the Vesting Date); provided that the Participant has satisfied all of the tax withholding obligations described in Section 6 below, and that the Participant has completed, signed and returned any documents and taken any additional action that the Company deems appropriate to enable it to accomplish the delivery of the shares of Common Stock. The date upon which shares of Common Stock are to be issued under this Section 3 is referred to as the “Settlement Date.” The issuance of the shares of Common Stock hereunder may be effected by the issuance of a stock certificate, recording shares on the stock records of the Company or by crediting shares in an account established on the Participant’s behalf with a brokerage firm or other custodian, in each case as determined by the Company. Fractional shares will not be issued pursuant to the Award.

Notwithstanding the above, (i) the Company shall not be obligated to deliver any shares of the Common Stock during any period when the Company determines that the delivery of shares hereunder would violate any federal, state or other applicable laws, (ii) the Company may issue shares of Common Stock hereunder subject to any restrictive legends that, as determined by the Company’s counsel, are necessary to comply with securities or other regulatory requirements, and (iii) the date on which shares are issued hereunder may include a delay (which delay shall in no event extend beyond 30 days following the Vesting Date) in order to provide the Company such time as it determines appropriate to address tax withholding and other administrative matters.

Participant shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any RSUs unless and until shares of Common Stock settled for such RSUs shall have been issued by the Company to Participant (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company).

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any shares of Common Stock issued pursuant to Vested RSUs, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other holders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

The Company has the right to deduct or otherwise effect a withholding of the amount of any taxes (including, but not limited to, any FICA, FUTA, and similar taxes) required by federal, state, local or foreign laws to be withheld or otherwise deducted and paid with respect to the

2

grant, vesting or settlement of the Restricted Stock Units; or, in lieu of such withholding, to require that the Grantee pay to the Company in cash (or, at the sole discretion of the Committee, in the form of shares of Common Stock or net settlement of the Award) the amount of any taxes required to be withheld or otherwise deducted and paid by the Company or any Subsidiary in connection with the grant, vesting or settlement of the Restricted Stock Units. Unless the tax withholding obligations of the Company or any affiliate are satisfied, the Company will have no obligation to issue a certificate for any of the shares of Common Stock otherwise issuable pursuant to the Award (whether vested or unvested).

The Participant understands, acknowledges and agrees that, except as otherwise provided in the Plan or as permitted by the Committee, the Award may not be sold, assigned, transferred, pledged or otherwise directly or indirectly encumbered or disposed of other than by will or the laws of descent and distribution.

In addition, unless otherwise determined by the Committee, the Participant shall not be permitted, for a period of one year following the Vesting Date, to sell, assign, transfer, pledge or otherwise directly or indirectly encumber or dispose of, other than by will or the laws of descent and distribution, any the shares of Common Stock issued to the Participant hereunder (net of any shares withheld or disposed of to fund withholding taxes), if any, upon vesting and settlement of the Award pursuant to Section 3 and 4 hereof.

The Grant Notice, these Standard Terms and Conditions and the Plan constitute the entire understanding between the Participant and the Company regarding the Award. Any prior agreements, commitments or negotiations concerning the Award are superseded.

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common Stock, if any, as shall have been issued to such person in connection with the Award. Nothing in the Plan, in the Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue in the Company’s employ or service nor limit in any way the Company’s right to terminate the Participant’s employment at any time for any reason.

Notwithstanding any other provision of the Plan or these Standard Terms and Conditions, this Award is not intended to provide for a deferral of compensation within the meaning of Section 409A of the Code and is intended to qualify for as a “short-term deferral” under Section 409A of the Code, and these Standard Terms and Conditions shall be construed or deemed to be amended

3

as necessary to effect such intent. Under no circumstances, however, shall the Company have any liability under the Plan or these Standard Terms and Conditions for any taxes, penalties or interest due on amounts paid or payable pursuant to the Plan or these Standard Terms and Conditions, including any taxes, penalties or interest imposed under Section 409A of the Code.

By executing the Grant Notice, the Participant hereby consents to the delivery of information (including, without limitation, information required to be delivered to the Participant pursuant to applicable securities laws) regarding the Company and the Subsidiaries, the Plan, and the Restricted Stock Units via Company web site or other electronic delivery.
