9, 2017 (the “Effective Date”) by and between Drone Aviation Holding Corp., a Nevada corporation (the “Company”)
and ________________________ (the “Holder”) (collectively the “Parties”).


 


BACKGROUND


 


A.    
The Company and Holder are the parties to that certain Convertible Promissory Note Series 2016, originally issued by the
Company to the Holder on September 29, 2016, in the original principal amount of $1,500,000.00 (the “Note”);


 


B.    
The Parties amended the Note on August 3, 2017 pursuant to the terms of an Amendment to Convertible Promissory Note (the
“August 2017 Amendment”);


C.    
The Parties desire to further amend the Note as amended by the August 2017 Amendment, as set forth below.


 


NOW THEREFORE, in consideration
of the execution and delivery of the November 2017 Amendment and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties agree as follows:


 


1.          Sections 1(a), 1(b) and 1(f) of the Note shall be replaced in its entirety with the following new sections:


 


(a)        Section
1(a) – Payment of Principal and Interest; Prepayment. Subject to the terms of this Note, the Company shall pay the outstanding
principal amount of this Note and any accrued and unpaid interest on the Maturity Date. In addition, at the Holder’s election,
accrued and unpaid interest shall be payable in monthly or quarterly payments at any time after the Effective Date in the manner
provided for in Section 1(b). Prepayment of this Note may be made at any time without penalty.


 


(b)       Section
1(b) - PIK Shares. In the event the Company does not prepay this Note in full before the Maturity Date, then the Company
shall satisfy its obligation to repay the outstanding principal amount of this Note and any accrued and unpaid interest with: (i)
cash; (ii) the issuance and delivery to the Holder of whole shares (“PIK Shares”) of common stock of the Company, par
value $0.0001 per share (“Common Stock”) at the Conversion Price in accordance with the procedures set forth in Section
2; or (iii) any combination of cash and PIK Shares, as determined by the Holder in its sole discretion.


 


(c)       Section
1(f) - Number and Value of PIK Shares. The PIK Shares issued and delivered upon prepayment of any principal, accrued interest
or at maturity shall be equal to the number of shares of Common Stock that could have been purchased for the principal and interest
obligation (less any cash paid in combination with the PIK Shares) if the shares were valued at the Conversion Price.


 


2.         
This November 2017 Amendment shall be deemed part of, but shall take precedence over and supersede any provisions to the
contrary contained in the Note. All initial capitalized terms used in this November 2017 Amendment shall have the same meaning
as set forth in the Note unless otherwise provided. Except as specifically modified hereby, all of the provisions of the Note,
which are not in conflict with the terms of this November 2017 Amendment, shall remain in full force and effect.
