MUSTANG BIO, INC.

2016 STOCK INCENTIVE PLAN

RESTRICTED STOCK UNIT AWARD AGREEMENT

This Restricted Stock Unit Award Agreement (this “Agreement”) is made and entered into between Mustang Bio, Inc. (the “Company”) and [] (“Grantee”), effective as of [] (such date the “Date of Grant”).  This Agreement sets forth the terms and conditions associated with the Company’s award to Grantee of Restricted Stock Units payable as described below in shares of Common Stock from the Company pursuant to the Company’s 2016 Stock Incentive Plan (the “Plan”) for the number of Units set forth below (collectively, the “Award”).  Capitalized terms used herein which are not otherwise defined herein will have the meanings ascribed to them under the Plan.

NOW, THEREFORE, in consideration of the foregoing and Grantee’s continued provision of valuable services as an employee or consultant of the Company, it is agreed by and between the parties as follows:

1.Grant of Units.  Effective as of the Date of Grant, the Company hereby grants the Grantee [     ] Restricted Stock Units (the “Units”).  The Units are subject to the vesting, payment, and other provisions of this Agreement and the Plan.  Each Unit represents the value of one (1) share of Common Stock of the Company (a “Share”).  The Company will account for the Units in a bookkeeping account on the Grantee’s behalf until they become payable or are forfeited.

2.Vesting.  The Units are unvested when granted, and will vest as described below, provided that vesting may accelerate or cease as provided for in this Agreement or in the Plan.

[Vesting Schedule]

3.Effect of Termination of Continuous Service.  In the event of the termination of Grantee’s Continuous Service, all Units that are not vested will be forfeited.

4.Delivery of Shares to Settle Vested Units.  Units vested as provided in Section 2 will be settled by delivering to Grantee a number of Shares equal to the number of vested Units as soon as practicable after the vesting date, provided that the Company may provide a reasonable delay in the issuance or delivery of the Shares to address tax withholding and other administrative matters and provided further that delivery of the Shares will occur no later than two and one-half months following the conclusion of the year in which the vesting occurs.  On such date, the Company will, at its election, either: (a) issue a certificate representing the Shares payable pursuant to this Agreement; or (b) not issue any certificate representing the Shares payable pursuant to this Agreement and instead document the Grantee’s interest in the Shares by registering such Shares with the Company’s transfer agent (or another custodian selected by the Company) in book­entry form in the Grantee’s name.

5.Capitalization Changes.  The number of Units convertible to Shares subject to this Award may be adjusted from time to time by the Administrator to account for changes in capitalization as described in Section 12 of the Plan.

​

​

​

6.Rights as a Stockholder.  The Units represent a right to payment from the Company if the conditions of the Agreement are met and do not give the Grantee ownership of any Common Stock prior to delivery as provided in Section 4.  Grantee shall not have any rights and/or privileges of a stockholder of the Company with respect to the Units prior to such delivery.  If Grantee becomes vested in Units as provided in Section 2, any Shares to which Grantee becomes entitled shall be delivered to Grantee as provided in Section 4, and Grantee shall have full ownership of the Shares upon such delivery.

7.Non-Transferability of the Award.  The Units and the right to payment under this Agreement are not transferable, may not be sold, exchanged, transferred, pledged, hypothecated, encumbered or otherwise disposed of except as provided in the Plan.  Any purported transfer of the Units or the right to payment under this Agreement is null and void and will not be given effect.

8.Award Not An Employment Agreement.  The Award is not an employment or service contract, and nothing this Agreement confers or will be construed as conferring upon the Grantee any right to continue in the employment or service of the Company, or as interfering with or restricting in any way the right of either party to terminate such employment or service at any time.

9.Tax Consequences.  Grantee acknowledges that he/she understands the federal, state, and local tax consequences of the Award and the issuance, vesting, forfeiture, and delivery provisions hereof relating to the Units.  Grantee will rely solely on the advice of his/her own tax advisors and not on any statements or representations of the Company or any of its agents.  Grantee understands that Grantee (and not the Company) shall be responsible for his/her own tax liability that may arise as a result of the Award or the transactions contemplated by this Agreement.

10.Withholding Obligations.  Grantee understands that, at the time that Grantee becomes vested and/or receives payment for any Units (including through the delivery of Shares), the Company may be required to withhold federal, state and local income and employment taxes.  At the time of vesting, or at or before the time Grantee receives a distribution of the Shares underlying the Units or other consideration, or at any time thereafter as requested by the Company, Grantee hereby authorizes the Company to satisfy any required withholding to satisfy federal, state, local, payroll, and foreign tax withholding obligations of the Company or any Affiliate that arise in connection with the Units (the “Withholding Taxes”).  Notwithstanding any other provision of this Section, the Company may, in its sole discretion, satisfy all or any portion of the Withholding Taxes obligation relating to the Units by any of the following means or by a combination of such means:  (a) withholding from any compensation otherwise payable to the Grantee by the Company; (b) causing the Grantee to tender a cash payment; or (c) withholding Shares from the Shares issued or otherwise issuable to Grantee in connection with the Units with a Fair Market Value (measured as of the date the Withholding Taxes are to be determined) equal to the amount of such Withholding Taxes; provided, however, that the number of such Shares so withheld shall not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income (or such lesser amount as may be necessary to avoid classification of the Units as a liability for financial accounting purposes).  Grantee understands that all matters with respect to the total amount of taxes to be withheld in respect of such compensation income will be determined by the Administrator in its reasonable discretion. Grantee further understands that, although the Company may pay withheld amounts to the applicable taxing authorities, the Grantee is responsible for payment of all taxes due as a result of compensation arising under the Agreement.

11.Data Privacy.  Grantee acknowledges that the Company holds certain personal information about Grantee, including, but not limited to: name, home address and telephone number, date of birth, social security number or other identification number, compensation, nationality, job title, details of the Award, and any other entitlement to shares of stock awarded, cancelled, exercised, vested or unvested.  Grantee consents to the collection, use and transfer, in electronic or other form, of such personal data for the purpose of implementing, administering, and managing this Award.

(d)The Company makes no representations to Grantee regarding the compliance of this Agreement or the Units with Section 409A, and Grantee is solely responsible for the payment of any taxes or penalties arising under Section 409A(a)(1), or any state law of similar effect, with respect to the grant or vesting of the Units or the delivery of the Shares subject to this Award.
