This
Current Report (the “Current Report”) is being filed to update and supplement the definitive proxy statement (the “Definitive
Proxy Statement”) filed by GX with the Securities and Exchange Commission (the “SEC”) relating to GX’s special
meeting of its stockholders (the “Special Meeting”), which will be held on March 20, 2023 at 10:30 a.m., Eastern time, at
the following address: https://www.ctsproxy.com/gx2/ext2023. The Definitive Proxy Statement was declared effective on February 9, 2023
and was sent to all GX stockholders on or about February 10, 2023.
GX
is providing this corrected disclosure to the Definitive Proxy Statement (the “Supplement”) solely to clarify that GX will
not use the proceeds placed in the Trust Account and the interest earned thereon to pay any excise tax imposed under the Inflation Reduction
Act of 2022 (“IR Act”) on any redemptions or stock buyback by GX, which appears on page 20 of the Definitive Proxy Statement.
The
corrected disclosures below should be read in conjunction with the disclosures contained in the Definitive Proxy Statement, which should
be read in its entirety. To the extent the information set forth herein differs from or updates information contained in the Definitive
Proxy Statement, the information set forth herein shall supersede or supplement the information in the Definitive Proxy Statement. All
page and paragraph references used herein refer to the Definitive Proxy Statement before any additions or deletions resulting from the
revised disclosures, and capitalized terms used but not otherwise defined in this Current Report or the Supplement have the meanings
set forth in the Definitive Proxy Statement. From and after the date of this Current Report, any references to the “definitive
proxy statement” in the Definitive Proxy Statement are to the Definitive Proxy Statement as supplemented hereby.
If
you have not already submitted a proxy card for use at the Special Meeting, you are urged to do so promptly. This Current Report does
not affect the validity of any proxy card or voting instructions that GX stockholders may have previously received or delivered. No action
is required by any GX stockholder who has previously delivered a proxy or voting instructions and who does not wish to revoke or change
that proxy or voting instructions.
Corrected
Disclosure
Any
redemption or other repurchase that occurs after December 31, 2022, in connection with a Redemption Event may be subject to the
excise tax. Pursuant to the rules set forth in the Notice, however, redemptions in connection with a liquidation of the Company
should not be subject to the excise tax. Whether and to what extent GX would be subject to the excise tax in connection
with a Redemption Event would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases
in connection with the Redemption Event, (ii) the structure of the business combination, (iii) the nature and amount of any
“PIPE” or other equity issuances in connection with the business combination (or otherwise issued not in connection with
the Redemption Event but issued within the same taxable year of the business combination) and (iv) the content of regulations and
other future guidance from the Treasury. In addition, because the excise tax would be payable by GX, and not by the redeeming
holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the
cash available on hand to complete a business combination and in GX’s ability to complete a business combination, including the
Transactions. Nonetheless, we will not use the proceeds placed in the Trust Account and the interest earned thereon to pay
any excise tax imposed under the IR Act on any redemptions or stock buybacks by GX.
All
the other information in the Definitive Proxy Statement and the proxy card remains unchanged. We have not changed or added to the matters
to be considered by our stockholders at the Special Meeting, and this Current Report does not change the recommendation of our board
of directors with respect to the Charter Amendment Proposal or the Adjournment Proposal described in the Definitive Proxy Statement.

“intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,”
“could,” “may,” “might,” “possible,” “potential,” “predict,”
“should,” “would” and other similar words and expressions, but the absence of these words does not mean that
a statement is not forward-looking.
The
forward-looking statements are based on the current expectations of the management of NioCorp and GX, as applicable, and are inherently
subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of such statement. There
can be no assurance that future developments will be those that have been anticipated. Forward-looking statements reflect material expectations

the financial and capital markets; NioCorp and GX being able to receive all required regulatory, third-party and shareholder approvals
for the proposed Transaction; the amount of redemptions by GX public shareholders; the consummation of the convertible debenture transaction
and the stand-by equity purchase facility contemplated by the definitive agreements with Yorkville; and other current estimates and assumptions
regarding the proposed Transaction and its benefits. Such expectations and assumptions are inherently subject to uncertainties and contingencies
regarding future events and, as such, are subject to change. Forward-looking statements involve a number of risks, uncertainties or other
factors that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking
statements. These risks and uncertainties include, but are not limited to, those discussed and identified in public filings made by NioCorp
and GX with the SEC and, in the case of NioCorp, with the applicable Canadian securities regulatory authorities and the following: the
amount of any redemptions by existing holders of GX Class A Shares being greater than expected, which may reduce the cash in trust available
to NioCorp upon the consummation of the Transaction; the occurrence of any event, change or other circumstances that could give rise
to the termination of the Business Combination Agreement and/or payment of the termination fees; the outcome of any legal proceedings
that may be instituted against NioCorp or GX following announcement of the Business Combination Agreement and the Transaction; the inability
to complete the proposed Transaction due to, among other things, the failure to obtain NioCorp shareholder approval or GX shareholder
approval or the consummation of the convertible debenture transaction and the stand-by equity purchase facility contemplated by the definitive

and production activities; feasibility study results; changes in demand for and price of commodities (such as fuel and electricity) and
currencies; changes or disruptions in the securities markets; legislative, political or economic developments; the need to obtain permits
and comply with laws and regulations and other regulatory requirements; the possibility that actual results of work may differ from projections/expectations
or may not realize the perceived potential of NioCorp’s projects; risks of accidents, equipment breakdowns, and labor disputes
or other unanticipated difficulties or interruptions; the possibility of cost overruns or unanticipated expenses in development programs;
operating or technical difficulties in connection with exploration, mining, or development activities; the speculative nature of mineral
exploration and development, including the risks of diminishing quantities of grades of reserves and resources; claims on the title to
NioCorp’s properties; potential future litigation; and NioCorp’s lack of insurance covering all of NioCorp’s operations.
Should
one or more of these risks or uncertainties materialize or should any of the assumptions made by the management of NioCorp and GX prove
incorrect, actual results may vary in material respects from those projected in these forward-looking statements.
All
subsequent written and oral forward-looking statements concerning the proposed Transaction or other matters addressed in this Current
