	 	Re.	Maturity Date Extension




 


Dear
Sir/Madam:


 


Reference
is hereby made to that certain Convertible Debenture, dated as of May 7, 2015 (as amended, the "Debenture") with a principal
amount of $200,000
(the "Principal Amount") and an interest rate of 9% (the "Initial
Interest Rate") of the Principal Amount, issued in favor of Brothers Consulting LLC ("Brothers Consulting") by
Sports Field Holdings, Inc., a Nevada corporation (the "Company").


 


The
Debenture was amended by that certain extension letter dated March 30, 2016 (the "Extension Letter"). Pursuant to the
Extension Letter, the Maturity Date (as defined in the Debenture) is currently July 1, 2016. The Extension Letter also increased
the Principal Amount to $218,000 and maintained the Initial Interest Rate.


 


In
consideration of the Company issuing Brothers Consulting 40,000 shares of the Company's restricted common stock (the "Stock
Issuance" separate and in addition to the 40,000 shares of the Company's restricted common stock already held by Brothers
Consulting) and adding $15,000 to the Principal Amount, among other consideration, Brothers Consulting hereby agrees to extend
the Maturity Date to January 1, 2017. Brothers Consulting and the Company hereby agree that, following the execution of this letter
agreement and the Stock Issuance and effective as of August 1, 2016 (the "Effective Date"), the definition of "Maturity
Date" in the Debenture is hereby replaced in its entirety and as of the Effective Date means "January 1, 2017".
In addition, the interest amount of $9,810
shall be added to the Principal Amount of the Debenture as of the Effective Date. The Debenture shall pay interest as of the Effective
Date at a rate of 15% per annum, in lieu of the Initial Interest Rate, payable in one lump sum on the Maturity Date. For the avoidance
of doubt, as of the Effective Date, the Principal Amount of the Debenture is $242,810.


 


In
addition, Section LA of the Debenture shall be amended and restated in its entirety to read:


 


"Conversion
Price. On any Conversion Date from August 9, 2016 through January 1, 2017, the Debenture is convertible into shares of the
Company's common stock (the “Conversion Shares") at a conversion price of US$1.00
per share. On any Conversion Date after January 1, 2017, the Debenture is convertible into
Conversion Shares at a conversion price that is the lower of (i) US$1.00 per share and (ii) the VWAP
(as defined below) for the last five trading days preceding the Conversion Date. "VWAP" means, for any
date, the volume-weighted average price of the Company's common stock on the Principal Market for a particular Trading Day or
set of Trading Days, as the case may be, as reported by Bloomberg. "Trading Day" means any day during which the
principal market on which the Company's common stock is traded (the "Principal Market") shall be open for business."
