ASSEMBLY BIOSCIENCES, INC. 


RESTRICTED STOCK UNIT AWARD AGREEMENT


UNDER THE 2017 INDUCEMENT AWARD PLAN





 


THIS RESTRICTED
STOCK UNIT AWARD AGREEMENT (this “Award Agreement”) is made and entered into by and between Assembly Biosciences,
Inc. (the “Company”) and the individual named in the Restricted Stock Unit Award Notice (the “Grantee”)
under the Company’s 2017 Inducement Award Plan (the “Plan”). The Award Notice also establishes
the Effective Date of the Award, the number of Restricted Stock Units awarded, vesting conditions, and the Payment Date of the
Award.


 


WHEREAS, the Grantee is expected to become
an employee of the Company;


 


WHEREAS, the Company considers it desirable
and in the best interests of the Company that the Grantee be given an opportunity to acquire a proprietary interest in the Company
as an incentive to advance the interests of the Company and to perform future services that will contribute materially to the successful
operation of the Company; and


 


WHEREAS, the Award granted hereby is a material
inducement for the Grantee to enter into employment with the Company and to promote the success of the Company’s business;
and


 


WHEREAS,
the Company, acting through the Board of Directors of the Company (the “Board”) or (ii) the
Committee appointed by the Board under the Plan (the “Committee”), desires to
grant the Grantee a Restricted Stock Unit Award measured in shares of common stock of the Company (the “Common Stock”),
in accordance with the Plan. Capitalized terms used herein which are not otherwise defined herein shall have the meanings ascribed
to them under the Plan.


 


NOW, THEREFORE, in consideration of the
premises, it is agreed by and between the parties as follows:


 


1.         Grant
of Restricted Stock Unit Award. The Company awards the Grantee Restricted Stock Units in a number that is specified
in the Award Notice provided to the Grantee. The Award is subject to the vesting, payment and other provisions of this Award Agreement,
the Award Notice and the Plan. Each Restricted Stock Unit represents one (1) Share of Common Stock of the Company. The Company
will account for the Restricted Stock Units in a bookkeeping account on the Grantee’s behalf until they become payable or
are forfeited. The number of Restricted Stock Units shall be adjusted if the Common Stock is split, combined, if stock dividends
are paid on Common Stock, or upon a similar event in the same manner that the Common Stock
is adjusted.


 


2.         Dividend
Equivalents. For each Restricted Stock Unit that is granted and credited to the Grantee’s account, the Grantee’s
account will also be credited with a Dividend Equivalent Rights in an amount equal to any cash dividends paid by the Company upon
one Share of Common Stock after the Effective Date and before the Payment Date (as provided in the Award Notice) for the Restricted
Stock Unit, subject to the vesting and other provisions of this Award Agreement and the Award Notice.


 




    	 	 	 



     


    

 


 


3.          Vesting.
The Restricted Stock Units (and Dividend Equivalent Rights associated with the Restricted Stock Units) shall be unvested and shall
be subject to the restrictions set forth in this Award Agreement and the Award Notice. Unless sooner forfeited in accordance with
Section 5, the Restricted Stock Units and Dividend Equivalent Rights associated with the Restricted Stock Unit shall be vested
for a Grantee as set forth in the Grantee’s Award Notice.


 


4.          Settlement
of Vested Restricted Stock Units and Restricted Dividend Equivalents.If any of the Restricted Stock Units vest on a Vesting
Date, the Company shall settle such Restricted Stock Units (the “Vested Restricted Stock Units”) and Dividend
Equivalent Rights attributable to such Vested Restricted Stock Units (“Vested Dividend Equivalents”) on the
Payment Date established in the Award Notice (the “Payment Date”) by delivering to the Grantee (a) a certificate
for shares of Common Stock of the Company and (b) cash, determined as follows:


 


		(a)	Number of Shares of Common Stock. The Company will determine the value as of the Payment Date of the Vested Restricted
Stock Units and the Vested Dividend Equivalent Rights (together, the “Total Amount”). For this purpose, the
Vested Dividend Equivalents shall be valued at their original value and shall not be increased or decreased by an interest or earnings
factor. The Total Amount will be reduced by any tax withholding that is not paid by the Grantee under the procedure in Section
6 below (the amount after the reduction is the “Net Amount”). The Net Amount will be divided by the value of
one (1) Common Share of the Company as of the Vesting Date, and the resulting whole number (without remainder) shall be the number
of shares of Common Stock that will be delivered to the Grantee, and



 


		(b)	Cash. The remainder resulting from the division in (a) above to determine the number of shares of Common Stock will
be the dollar amount of the cash payable to the Grantee, and such amount shall be paid to the Grantee by check.



 


The Vested Restricted Stock Units and Vested
Dividend Equivalents will be settled by the Company within thirty (30) days of the Payment Date.


 


5.          Forfeiture
of Restricted Stock Units (and Dividend Equivalent Rights Attributable to Restricted Stock Units). In the event of Termination
of Employment of the Grantee from the Company for any reason (including Disability), any Restricted Stock Units and Dividend Equivalent
Rights attributable to such Restricted Stock Units that were not already vested on the termination of Employment shall be forfeited
on that date.


 


6.          Certain
Tax Matters. The Grantee acknowledges that the Grantee understands the federal, state and local income, employment and foreign
(if applicable) tax consequences of the Restricted Stock Unit Award, and the issuance, vesting and forfeiture provisions relating
to the Restricted Stock Unit Award.


 


 


 




    	 	 	 



     


    

 


The Grantee understands that, at the time
that the Grantee realizes any compensation income in respect of the Restricted Stock Unit Award, the Company will be required to
withhold federal, state and local income and employment taxes on the full amount of the compensation income realized by the Grantee,
and if the Grantee is located outside of the United States, the Company may be required to withhold to meet tax, employment, or
other obligations imposed by the tax jurisdiction that may be applicable to the Grantee. It is understood that all matters with
respect to the total amount of taxes to be withheld in respect of such compensation income shall be determined by the Board (or
the Committee) in its reasonable discretion. It is understood that although the Company may pay withheld amounts for the taxing
jurisdiction that may be credited to the Grantee against taxes due by the Grantee, the Grantee is responsible for payment of all
taxes due as a result of compensation arising under this Award Agreement.


 


The Board (or the Committee) may make such
provisions and take such steps as it may deem necessary or appropriate for the withholding of taxes by the Company on compensation
income the Grantee realizes. The Company shall accept payment by the Grantee of an amount in cash for all or part of the
withholding obligation of the Company on the compensation income, so that the payment(s) to the Grantee under this Award Agreement
are not reduced for tax withholding to the extent of the payment. Such payment by the Grantee must be made to the Company by the
time that the Company is required to pay the withholding to the taxing authority, but in any event not later than thirty (30) days
from the Payment Date. If the Grantee does not make a payment for the full withholding obligation, the Company shall withhold part
of the payment due for redemption of the Vested Restricted Stock Units and Vested Dividend Equivalent Rights in the amount needed
by the Company to meet its withholding obligations, with the result that the payment amount for the Vested Restricted Stock Units
and Vested Dividend Equivalent Rights will be reduced as provided in Section 4(a) above by the amount needed to meet the Company’s
withholding obligations.


 


7.          Rights
Prior to Vesting. The Restricted Stock Units and Dividend Equivalent Rights represent a right to payment from the Company if
the conditions of this Award Agreement are met and do not give the Grantee ownership of any Common Stock prior to delivery as provided
in Section 4. No assets have been set aside by the Company or otherwise to pay the amounts promised by this Award Agreement, the
right to payment is unsecured, and the Grantee is a general creditor of the Company for payment under this Award Agreement.


 


8.          Investment
Representation. The Grantee represents and warrants to the Company that the Grantee has read this Award Agreement carefully,
and to the extent believed necessary, has discussed this Award Agreement and its impact and limitations upon the Grantee with counsel.


 


9.          Transferability.
The right to payment under this Award Agreement may not be sold, exchanged, transferred, pledged, hypothecated, encumbered or otherwise
disposed of except as provided in the Plan. The Company shall have the right to assign to any of its affiliates any of its rights,
or to delegate to any of its affiliates any of its obligations under this Award Agreement.

incorporated by reference herein, and to the extent that any conflict may exist between any term or provision of this Award
Agreement and any term or provision of the Plan as in effect from time to time, such term or provision of the Plan shall
control.


 


13.        Certain
Remedies. Without intending to limit the remedies available to the Company, the Grantee agrees that damages at law will be
an insufficient remedy in the event the Grantee violates the terms of this Award Agreement. The Grantee agrees that the Company
may apply for and have injunctive or other equitable relief in any court of competent jurisdiction to restrain the breach or threatened
breach of, or otherwise specifically to enforce, any of the provisions hereof.


 


14.          Waiver.
The waiver by either party of compliance with any provision of this Award Agreement by the other party shall not operate or be
construed as a waiver of any other provision of this Award Agreement, or of any subsequent breach by such party of a provision
of this Award Agreement.


 


15.         No
Restriction on Right of Company to Effect Corporate Changes. Neither the Plan nor this Award Agreement shall affect in
any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations
or other changes in the capital structure or business of the Company, or any merger or consolidation of the Company, or any issue
of stock or of options, warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks whose
rights are superior to or affect the Common Stock or the rights thereof or which are convertible into or exchangeable for Common
Stock, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the assets or business of
the Company, or any other corporate act or proceeding, whether of a similar character or otherwise.

incorporated herein) sets forth all of the promises, agreements, conditions and understandings between the parties hereto with

written, express or implied, between them with respect to the Restricted Stock Unit Award other than as set forth therein or herein.
This Award Agreement supersedes and replaces any and all prior agreements between the parties hereto with respect to Restricted
Stock Units and Dividend Equivalent Rights. This Award Agreement is, and is intended by the parties to be, an integration of any
and all prior agreements or understandings, oral or written, with respect to Restricted Stock Units and Dividend Equivalent Rights.
No modification, amendment or waiver of any of the provisions of this Award Agreement shall be effective unless approved in writing
by both parties.

provision was omitted.

the granting or vesting of the Restricted Stock Units and Dividend Equivalent Rights nor
any other provision of this Award Agreement shall be construed as conferring upon the Grantee any right to continue in the employment

(b)          The
Company, the Board (or the Committee) and any employees or agents thereof are relieved from any liability for the non-issuance
or non-transfer, or any delay in the issuance or transfer, of any Common Stock which results from the inability of the Company
to obtain, or in any delay in obtaining, from each regulatory body having jurisdiction all requisite authority to issue or transfer
the Common Stock in satisfaction of this Award Agreement if counsel for the Company deems such authorization necessary for the
lawful issuance or transfer of any of the Common Stock.


 


(c)          
No Common Stock shall be sold or otherwise disposed of in violation of any federal or state securities law or regulations.
