NioCorp Developments Ltd. (TSE:NB) Files An 8-K Entry into a Material Definitive Agreement

Item 1.01

Lind First Tranche Increase

As previously announced, on December 14, 2015, NioCorp
Developments Ltd. (the Company) entered into a definitive
convertible security funding agreement (the Lind Agreement) with
an entity managed by The Lind Partners, a New York-based asset
management firm (collectively with The Lind Partners, Lind). A
first tranche $4.5 million was made in a series of advances
between December 22, 2015 and January 19, 2016, to the issuance
of an initial convertible security with a face value of $5.4
million during the same period (the Initial Convertible
Security). Further to the terms of the Lind Agreement, upon
satisfaction of certain conditions, including but not limited to,
a minimum draw down amount by Lind under the Initial Convertible
Security, a minimum market capitalization for the Company and a
minimum amount of cash on the Companys balance sheet, the Company
had the right to call an additional $1.0 million under the
Initial Convertible Security (a First Tranche Increase).

On February 14, 2017, upon satisfaction of the conditions for the
First Tranche Increase, the Company provided notice to Lind to
demand the advancement of an additional $1.0 million in funding
under the Initial Convertible Security to its right to call. As a
result, upon payment of the additional $1.0 million in funding by
Lind to the Company, the face amount of the Initial Convertible
Security will be increased by $1.2 million ($1.0 million in
additional funding and $200,000 in implied interest amount). In
connection with the Convertible Security Increase, the Company is
obligated to issue Lind common share purchase warrants of the
Company (the Warrants). The Warrants will have a term of 36
months from issuance, and the number of Warrants to be issued
will be equal to $1.0 million divided by the volume-weighted
average price of the Companys common shares on the TSX (the VWAP)
for the five (5) consecutive trading days immediately before the
Convertible Security Increase funding is received, multiplied by
0.5. The exercise price of the Warrants issuable in connection
with the Convertible Security Increase will be equal to 120% of
the Companys five (5) trading day VWAP per share immediately
prior to the date the Convertible Security Increase is received.

Lind is entitled to convert the Initial Convertible Security in
monthly installments over its term at a price per share equal to
85% of NioCorps five-day trailing volume weighted average price
on the TSX (VWAP) prior to the date that notice of conversion is
provided by Lind. The Lind Agreement contains restrictions on how
much of the Initial Convertible Security may be converted in any
particular month. NioCorp has the option to buy back up to 70% of
the Initial Convertible Security in cash at any time for a
nominal premium. Lind is entitled to accelerate its conversion
right to the full amount of the face value of the Initial
Convertible Security or demand repayment thereof in cash upon a
default and other designated events.
