Capitalized terms not specifically defined in this Agreement have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the Plan.

ARTICLE I.

GENERAL

ARTICLE II.

VESTING; FORFEITURE; and Dividends

2.1 Restrictions. Restricted Stock granted under this Agreement may not be sold, assigned, transferred or otherwise encumbered or disposed of by the Participant prior to vesting.

2.2 Vesting of Restricted Stock. Except as may be otherwise provided below in Section 2.3 or 2.4, the Restricted Stock shall vest according to the vesting schedule in the Grant Notice, provided the Participant has continued in the employment or service of the Company or any Affiliate through the vesting dates (as applicable).

2.3 Accelerated Vesting. Notwithstanding the foregoing, a Participant’s unvested Restricted Stock shall vest in full immediately prior to the occurrence of a Change in Control.

2.4 Forfeiture. In the event of the Participant’s cessation of services (including, as applicable, a Termination of Service for any reason), all unvested Restricted Stock will immediately and automatically

be cancelled and forfeited, except as otherwise determined by the Administrator or provided in a binding written agreement between the Participant and the Company or any Affiliate.

2.5 Dividends. If the shares of Restricted Stock are outstanding on the record date for dividends or other distributions with respect to the Company’s Common Stock (whether made in cash or stock), dividends or distributions paid with respect to such shares during such period shall be held and the Participant shall accrue a right to receive a payment in respect of such dividends or distributions subject to the same vesting conditions and transfer restrictions as applicable to the underlying shares of Restricted Stock. All such dividend payments will be made no later than March 15 of the calendar year following the calendar year in which the right to dividend payment becomes non-forfeitable. Notwithstanding the foregoing, any extraordinary dividend or distribution paid with respect to the underlying shares of Restricted Stock during the applicable period shall be subject to such restrictions and vesting requirements as the Administrator may require.

ARTICLE III.

TAXATION; TAX WITHHOLDING; Section §83(b) Election

3.1 Representation. Participant represents to the Company that Participant has reviewed with Participant’s own tax advisors the tax consequences of this Award and the transactions contemplated by the Grant Notice and this Agreement (including without limitation any election made under Section 3.3 below). Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents.

3.2 Tax Withholding. In the event the Company determines that it must withhold any federal, state, and/or local taxes, the Company or any Affiliate has the authority and the right to deduct or withhold, or require Participant to remit to the Company or any Affiliate, an amount sufficient to satisfy federal, state, and local taxes (including, as applicable, the Participant’s FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of this Award. Except in the case where an election is made pursuant to Section 3.3 below, the Company shall have the authority to cause the required minimum tax withholding obligation to be satisfied, in whole or in part, by withholding from shares of Common Stock to be issued or released by the transfer agent a number of shares of Common Stock with an aggregate Fair Market Value that would satisfy the withholding amount due. The obligations of the Company under this Agreement will be conditional on such payment or arrangements, and the Company and, where applicable, its Affiliates will, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to Participant.

3.3 Election Under Section 83(b). The Participant and the Company hereby agree that the Participant may, within thirty (30) days following the Grant Date (consistent with Section 1.2), file with the Internal Revenue Service and the Company an election under Section 83(b) of the Internal Revenue Code. In the event the Participant makes such an election, such Participant agrees to promptly provide a copy of the election to the Company along with proof of the timely filing thereof with the Internal Revenue Service. The Participant acknowledges that he or she is responsible for obtaining the advice of his or her tax advisors with regard to the Section 83(b) election and that he or she is relying solely on such advisors and not on any statements or representations of the Company or any of its agents with regard to such election.

ARTICLE IV.

This Award and any amounts paid to the Participant hereunder, and any cash or other benefit acquired on the sale of shares of Common Stock distributed hereunder shall be subject to the provisions of the AST SpaceMobile, Inc. Policy for the Recovery of Erroneously Awarded Incentive-Based Compensation (as may be amended, restated, supplemented or replaced from time to time and include any successor policy or policies thereto) and any other clawback or recoupment policy implemented by the Company, whether or not such clawback policy was in place on the Grant Date.

By a notice given pursuant to this Section, either party may designate a different address for notices to be given to that party. Any notice will be deemed duly given when actually received, when sent by email, when sent by certified mail (return receipt requested) and deposited with postage prepaid in a post office or branch post office regularly maintained by the United States Postal Service or when delivered by a nationally recognized express shipping company.

4.6 Successors and Assigns. The Company may assign any of its rights under this Agreement to a single or multiple assignees, and this Agreement will inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth in this Agreement or the Plan, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto.

4.7 Limitations Applicable to Section 16 Persons. Notwithstanding any other provision of the Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the Grant Notice, this Agreement and the Restricted Stock will be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3) that are requirements for the application of such exemptive rule.
