	Re:	Letter of Engagement and Potential Offer of Employment

 

Dr. lanchulev:

 

The purpose of this letter
is to clarify and correct some language in your Letter of Engagement and Potential Offer of Employment (the "Offer Letter")
dated July 7, 2017 with the Eyenovia, Inc. (the
"Company").

 

Your annual salary is $384,996,
payable in monthly (or bi-weekly) installments of $32,083.
The Offer Letter inaccurately stated $32,083 as
your annual salary.

 

The plan referred to in
your Offer Letter under which you stock options have been issued is the 2014
Equity Incentive Plan not the 2013 Stock
Plan.

 

If you have any questions,
please feel fee to contact me. We look forward to continuing to work with you.

 

	 	Sincerely,
	 	 	 
	 	Eyenovia, Inc.

ARTICLE 2 – SCOPE OF
AGREEMENT

 

		2.1	Purpose. As a general form of contract, this Agreement allows the parties to contract multiple
projects or services through the issuance of Statements of Work without having to renegotiate the basic terms and conditions contained
in this Agreement. This Agreement covers the provision of services by The Party and/or its Affiliates, and accordingly, this Agreement
represents a vehicle by which Client can efficiently contract with The Party and/or its Affiliates for a broad range of services
related to the matters covered under this Agreement.

 

		2.2	Nature of Services. The services covered by this Agreement may include expert consultation,
administrative management, product development, project management, regulatory affairs, project management, contract management,
preclinical and clinical services, and other research and development services requested by Client and agreed to by The Party as
set forth in the relevant Statement of Work (the “Services”).

Work for each contracted project.

		(a)	The specific details of each project under this Agreement (the “Project”) will
be separately negotiated and specified in writing in a form acceptable to the Parties, and shall incorporate the terms of this
Agreement by reference and be deemed an integral part thereof (each such writing a “Statement of Work”). The
Statement of Work will include, as applicable, the name of the Parties, a description of the scope of work, timeline, budget, and
payment schedule. Each Statement of Work shall be subject to the terms and conditions of this Agreement, and to the extent that
any terms or provisions of a Statement of Work conflict with the terms and provisions of this Agreement, the terms and provisions
of this Agreement shall control, unless the applicable Statement of Work expressly states that is shall supersede this Agreement
on specific matters, in which case it shall supersede this Agreement with regard to the specific matter that is the subject of
that Statement of Work.

 

		(b)	In the event either Party desires to make any material changes to the Services to be performed
under a Statement of Work (“Changes”), such Changes must be agreed to in writing by the Parties. The Party will
prepare a draft Change Order for Client’s review that incorporates the requested Changes to the applicable Statement of Work
tasks, responsibilities, duties, budget, schedule, and all other relevant matters. The Party shall not be obligated to perform
any work related to such a Change until Client has given written approval to proceed and executed the Change Order. Notwithstanding
the foregoing, if Client otherwise directs The Party to commence work on any such Changes without executing a Change Order and
The Party undertakes such Changes, the draft Change Order will be deemed to have been accepted by Client, and Client shall be obligated
for all charges, schedules and duties associated therewith.

 

    	 	 	 

     

    

 

		2.5	Records. At the completion of the Services by
The Party, all Client property and Client Information, regardless of the method of storage or retrieval, shall be delivered to
Client in such form as is then currently in the possession of The Party. The Party, however, reserves the right to retain, at
its own cost and subject to the confidentiality provisions herein, one (1) copy of all Client property and Confidential Information
