Ladies and Gentlemen:


 


This
agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”)
between Energous Corporation, a Delaware corporation (the “Company”), and MDB Capital Group, LLC (“MDB”)
relating to a proposed underwritten public offering of shares (the “Shares”) of the Company’s Common Stock
(the “Common Stock”) and relates to shares of Common Stock issuable to
the undersigned upon the exercise of warrants to purchase Common Stock issued to the undersigned prior to the execution of the
Underwriting Agreement (the “Shares”).


 


In order to induce
MDB to enter into the Underwriting Agreement, and for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the undersigned agrees that, during the period beginning on and including the date of the Underwriting
Agreement through and including the one year anniversary of the date of the Underwriting Agreement (the “Lock-Up Period”),
the undersigned, or any affiliated party of the undersigned, will not, without the prior written consent of MDB and the Company,
directly or indirectly:


 


		(i)	offer, pledge, sell, contract to sell, sell any option or contract
to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer
or dispose of any of the Shares or any securities convertible into or exercisable or exchangeable for the Shares, whether now owned
or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition,
or 



 


		(ii)	enter into any swap or other agreement, arrangement or transaction
that transfers to another, in whole or in part, directly or indirectly, any of the economic consequence of ownership of the Shares
or any securities convertible into or exercisable or exchangeable for the Shares, 



 


whether any transaction described in clause (i)
or (ii) above is to be settled by delivery of Common Stock, other securities, in cash or otherwise. Moreover, if:


 


		(1)	during the last 17 days of the Lock-Up Period, the Company issues an earnings release or material
news or a material event relating to the Company occurs, or 



 


		(2)	prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings
results during the 16-day period beginning on the last day of the Lock-Up Period,



 


the Lock-Up Period shall be extended and
the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the date
of issuance of the earnings release or the occurrence of the material news or material event, as the case may be, unless MDB waives,
in writing, such extension.


 






    	 



    	 



    

 


The undersigned further
agrees that (i) it will not, during the Lock-Up Period (as the same may be extended as described above), make any demand for
or exercise any right with respect to the registration under the Securities Act of 1933, as amended (the “1933 Act”),
of any Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, and (ii) the Company
may, with respect to any Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock owned
or held (of record or beneficially) by the undersigned, cause the transfer agent or other registrar to enter stop transfer instructions
and implement stop transfer procedures with respect to such securities during the Lock-Up Period (as the same may be extended as
described above).


 


In addition, the undersigned
hereby waives any and all notice requirements and rights with respect to the registration of any securities pursuant to any agreement,
instrument, understanding or otherwise, including any registration rights agreement or similar agreement, to which the undersigned
is a party or under which the undersigned is entitled to any right or benefit and any tag-along rights or other similar rights
to have any securities (debt or equity) included in the offering contemplated by the Underwriting Agreement or sold in connection
with the sale of Common Stock pursuant to the Underwriting Agreement, provided that such waiver shall apply only to the public
offering of Common Stock pursuant to the Underwriting Agreement and each registration statement filed under the 1933 Act in connection
therewith.


 


The undersigned hereby
represents and warrants that the undersigned has full power and authority to enter into this agreement and that this agreement
has been duly executed and delivered by the undersigned and is a valid and binding agreement of the undersigned. This agreement
and all authority herein conferred are irrevocable and shall survive the death or incapacity of the undersigned and shall be binding
upon the heirs, personal representatives, successors and assigns of the undersigned.
