Item 1.01 Entry into a Material
Definitive Agreement.
Business Combination Agreement
On September 25, 2022, GX Acquisition Corp. II,
a Delaware corporation (“GXII”), NioCorp Developments Ltd., a company organized under the laws of the Province of British
Columbia (“NioCorp” or the “Company”) and Big Red Merger Sub Ltd, a Delaware corporation and a direct, wholly
owned subsidiary of NioCorp (“Merger Sub”), entered into a business combination agreement (the “Business Combination
Agreement”). As a result of the Transaction (as defined below), GXII will become a subsidiary of NioCorp.
The terms of the Business Combination Agreement, which contains customary
representations and warranties, covenants, closing conditions and other terms relating to the Transaction, are summarized below. Capitalized
terms used in this Current Report on Form 8-K but not otherwise defined herein have the meanings given to them in the Business Combination
Agreement.
Structure
Pursuant to the Business Combination Agreement,
among other transactions, the following transactions will occur: (i) Merger Sub will merge with and into GXII, with GXII surviving the
merger (the “First Merger”), (ii) all Class A shares in GXII (the “GXII Class A Shares”) that are held by shareholders
who have not elected to exercise their redemption rights in connection with the Transaction (the “GXII Public Shareholders”)
shall be converted into shares of Class A common stock in GXII (such shares, the “First Merger Class A Shares”), as the surviving
company in the First Merger, (iii) NioCorp will purchase all First Merger Class A Shares in exchange for common shares, no par value,
of NioCorp (“NioCorp Common Shares”) (the “Exchange”), (iv) NioCorp will assume the GX Warrant Agreement and each
GX Warrant that was issued and outstanding immediately prior to the effective time of the Exchange will be converted into a warrant to
acquire NioCorp Common Shares (a “NioCorp Warrant”), (v) all of the First Merger Class A Shares will be contributed by NioCorp
to 0896800 B.C. Ltd., a company organized under the laws of the Province of British Columbia and a direct, wholly owned subsidiary of
NioCorp (“Intermediate Holdco”), in exchange for additional shares of Intermediate Holdco, resulting in GXII becoming a direct
subsidiary of Intermediate Holdco, (vi) Elk Creek Resources Corporation, a Nebraska corporation and a direct, wholly owned subsidiary
of Intermediate Holdco (“ECRC”), will merge with and into GXII, with GXII surviving the merger as a direct subsidiary of Intermediate
Holdco (the “Second Merger”), and (vii) following the effective time of the Second Merger, each of NioCorp and GXII, as the
surviving company of the Second Merger, will effectuate a reverse stock split with the ratio to be mutually agreed by the parties. The
transactions contemplated by the Business Combination Agreement and the Ancillary Agreements (as defined below) are referred to, collectively,
as the “Transaction.”
Consideration
Pursuant to the Business Combination Agreement,
upon consummation of the First Merger, each GXII Class A Share that is held by a GXII Public Shareholder shall be converted into a First
Merger Class A Share. In connection with the Exchange, NioCorp will exercise its unilateral option to purchase each First Merger Class
A Share in exchange for 11.1829212 NioCorp Common Shares. As a result, each GXII Public Shareholder (excluding those who elect to exercise
their redemption rights in connection with the Transaction) will ultimately be issued NioCorp Common Shares.
Pursuant to the Business Combination Agreement,
upon consummation of the First Merger, each Class B share in GXII (other than certain shares that may be forfeited in accordance with
the GXII Support Agreement (as defined below)) will be converted into one share of Class B common stock in GXII (such shares, the “First
Merger Class B Shares”), as the surviving company in the First Merger. Upon consummation of the Second Merger, each of the First
Merger Class B Shares will be converted into 11.1829212 Class B common shares of GXII (each, a “Second Merger Class B Share”),
as the surviving company in the Second Merger. Each Second Merger Class B Share will be exchangeable into NioCorp Common Shares on a one-for-one
basis, subject to certain equitable adjustments, in accordance with the terms of the Exchange Agreement (further described below).
Pursuant to the Business Combination Agreement,
in connection with the First Merger and the assumption by NioCorp of the GX Warrant Agreement, each GX Warrant that is issued and outstanding
immediately prior to the Exchange Time shall be converted into one NioCorp Warrant pursuant to the GX Warrant Agreement. Each NioCorp
Warrant shall be exercisable solely for NioCorp Common Shares, and the number of NioCorp Common Shares subject to each NioCorp Warrant
shall be equal to the number of shares of GXII common stock subject to the applicable GX Warrant multiplied by 11.1829212, with the applicable
exercise price adjusted accordingly.
Following the effective time of the Second Merger,
NioCorp will effectuate a reverse stock split of the issued NioCorp Common Shares, and GXII will effectuate a proportionate reverse stock
split of the Second Merger Class A Shares and the Second Merger Class B Shares at a to-be-determined ratio.
GXII units, GXII Class A Shares and public warrants
are currently listed on The Nasdaq Stock Market LLC (“Nasdaq”), under the symbols “GXIIU,” “GXII”
and “GXIIW,” respectively. The NioCorp Common Shares are traded on the Toronto Stock Exchange (the “TSX”) under
the symbol “NB” and on the OTC Markets trading platform under the symbol “NIOBF.” NioCorp currently anticipates
that, following the Transaction, the NioCorp Common Shares will trade on Nasdaq and will continue to trade on the TSX. In addition, NioCorp
anticipates that, following the Transaction, the NioCorp Warrants will trade on Nasdaq. NioCorp intends to apply for listing of the NioCorp
Common Shares and NioCorp Warrants on Nasdaq. See “Closing Conditions” below. Neither Nasdaq nor the TSX has conditionally
approved any NioCorp listing application in connection with the Transaction and there is no assurance that such exchanges will approve
the listing applications.
Joint Proxy Statement/Prospectus and Shareholder Meetings
As promptly as practicable after the date of the Business Combination
Agreement, NioCorp will file with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4
(the “registration statement”), which will include (i) a joint proxy statement of GXII and NioCorp to solicit proxies to obtain
the GX Shareholder Approval and the Company Shareholder Approval at the GX Shareholder Meeting and the Company Shareholder Meeting, respectively,
and (ii) a prospectus of NioCorp under Section 5 of the Securities Act of 1933 (the “Securities Act”) with respect to the
NioCorp securities issuable in connection with the Transaction (as amended or supplemented from time to time, the “joint proxy statement/prospectus”).
The definitive joint proxy statement/prospectus will be sent to GXII and NioCorp shareholders and will be filed with the SEC and, in the
case of NioCorp, with the applicable Canadian securities regulatory authorities.
Closing
The closing (the “Closing”) will be
no later than the second business day following the satisfaction or waiver of all of the closing conditions (the “Closing Date”).
It is expected that the Closing will occur in the first quarter of 2023.

and officers of GXII (the “GXII Holders”), the directors and officers of NioCorp (the “NioCorp Holders” and, together
with the Sponsor and the GXII Holders, the “Holders”) will enter into a registration rights agreement (the “Registration
Rights Agreement”), pursuant to which, among other things, NioCorp will be obligated to file a shelf registration statement to register
the resale of certain securities of NioCorp held by the Holders after the Closing. The Registration Rights Agreement will also provide
the Holders with certain “demand” and “piggy-back” registration rights, subject to certain requirements and customary
conditions.

securities exchange or market on which such securities are then traded has equaled or exceeded the quotient of $13.42 per share divided
by 11.1829212 (as adjusted for stock splits (including the reverse stock split), recapitalizations and similar events) for 20 trading
days within any 30-trading day period commencing at least 150 days after the Closing Date or (b) the date on which NioCorp completes a
liquidation, merger, capital stock exchange, reorganization or similar transaction that results in all of NioCorp’s shareholders
having the right to exchange their NioCorp Common Shares for cash, securities or other property.
Exchange Agreement
Pursuant to the Business Combination Agreement,
in connection with the Closing, GXII, the Sponsor and NioCorp will enter into an exchange agreement (the “Exchange Agreement”),
pursuant to which, among other things, the Sponsor will be entitled to exchange any or all of its shares of Second Merger Class B Shares
in GXII for NioCorp Common Shares on a one-for-one basis, subject to certain equitable adjustments, in accordance with the terms of the
Exchange Agreement. Under certain circumstances, and subject to certain exceptions, NioCorp may instead settle all or a portion of any
exchange pursuant to the terms of the Exchange Agreement in cash, in lieu of NioCorp Common Shares, based on a volume-weighted average
price of NioCorp Common Shares.
Alternative Proposals
The Business Combination Agreement contains certain
non-solicitation restrictions prohibiting the parties’ and their affiliates and representatives from soliciting alternative acquisition
proposals from third parties or providing nonpublic information to, or participating in discussions or negotiations with, third parties
regarding alternative acquisition proposals, subject to certain exceptions related to proposals received by NioCorp that constitute a
Superior Proposal.

The Business Combination Agreement may be terminated
by GXII or NioCorp under certain circumstances, including, among others, (i) if GXII and NioCorp provide mutual written consent; (ii)
by either GXII or NioCorp if, prior to the Closing, the Transaction is enjoined, prohibited or otherwise restrained by the terms of a

the Business Combination Agreement results in or materially contributes to causing such Order to be issued or the failure of the Order
to be removed); (iii) by either GXII or NioCorp if the Closing does not occur on or before March 22, 2023, subject to certain extensions
as permitted under the Business Combination Agreement (provided, however, that the right to terminate the Business Combination Agreement
under the clause described in this clause (iii) will not be available to a party whose breach of any provision of the Business Combination
Agreement results in or materially contributes to causing the Closing to fail to occur prior to March 22, 2023, subject to certain extensions
as permitted under the Business Combination Agreement); (iv) by either GXII or NioCorp if the Company Shareholder Approval is not obtained
at the Company Shareholder Meeting; (v) by either GXII or NioCorp if the GX Shareholder Approval is not obtained at the GX Shareholder

by GXII of its covenants are not fulfilled as provided therein, subject to GXII’s cure right set forth therein; (vii) by NioCorp
in order to enter into a definitive agreement providing for a Superior Proposal; (viii) by GXII if NioCorp or Merger Sub breaches any
representation, warranty or covenant made by it in the Business Combination Agreement such that the conditions regarding the truth, completeness

are not fulfilled as provided therein, subject to NioCorp’s cure right set forth therein; or (ix) by GXII in the event of a change
of recommendation by the board of directors of NioCorp (the “NioCorp Board”) or the failure of the NioCorp Board to publicly
reaffirm its recommendation of the Business Combination Agreement and the Transaction.
Termination Fee
The Business Combination Agreement provides that,
upon termination of the Business Combination Agreement in specified circumstances, NioCorp must pay GXII a termination fee of $15,000,000
(the “Base Termination Fee”). Such specified circumstances include, among others, termination of the Business Combination
Agreement by NioCorp in order to enter into an agreement providing for a Superior Proposal, termination by GXII for a change of recommendation
of the NioCorp Board, or a material breach of certain of NioCorp’s covenants relating to soliciting acquisition proposals.
In addition, the Business Combination Agreement
provides that, upon termination of the Business Combination Agreement in specified circumstances, NioCorp is required to pay a termination
fee in the amount of $25,000,000 (the “Intentional Breach Termination Fee”). Such specified circumstances include, among others,
termination by GXII as a result of a willful and material breach by NioCorp such that certain conditions to Closing would not be satisfied
at Closing (subject to a cure period), or as a result of NioCorp’s failure to consummate the closing of the Transaction within five
business days after all the conditions to Closing have been satisfied and GXII has irrevocably confirmed in writing that it is prepared
to consummate the Closing.
In addition, the Business Combination Agreement
provides that, upon a termination of the Business Combination Agreement whereupon GXII will be entitled to the Base Termination Fee or
the Intentional Breach Termination Fee, NioCorp is also required to pay an amount equal to the sum of all documented and reasonable out-of-pocket
expenses paid or payable by GXII and the Sponsor in connection with the Business Combination Agreement and the Transaction, not to exceed
$5,000,000.
Pursuant to the Business Combination Agreement,
in no event will GXII be entitled to both the Base Termination Fee and the Intentional Breach Termination Fee.
The foregoing description of the Business Combination Agreement is
qualified in its entirety by reference to the full text of the Business Combination Agreement, a copy of which is filed as Exhibit 2.1
to this Current Report on Form 8-K and is hereby incorporated by reference into this Item 1.01. The Business Combination Agreement is
included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual
information about GXII, NioCorp or Merger Sub. In particular, the assertions embodied in representations and warranties by the parties
contained in the Business Combination Agreement are qualified by information in the disclosure schedules provided by the parties in connection
with the signing of the Business Combination Agreement. These disclosure schedules contain information that modifies, qualifies and creates
exceptions to the representations and warranties set forth in the Business Combination Agreement. Moreover, certain representations and
warranties in the Business Combination Agreement were used for the purpose of allocating risk between the parties, rather than establishing
matters as facts. Accordingly, investors and security holders should not rely on the representations and warranties in the Business Combination
Agreement as characterizations of the actual state of facts about GXII, NioCorp or Merger Sub.
GXII Support Agreement
On September 25, 2022, concurrently with the execution

to GXII’s Amended and Restated Certificate of Incorporation (the “GXII Charter”) to eliminate the automatic conversion
of shares of Class B Common Stock of GXII, all of which are held by the Sponsor, into GXII Class A Shares at the time of a Business Combination
(as defined in the GXII Charter), (ii) the Transaction, and (iii) any other proposals that are necessary to effectuate the Transaction.
With respect to certain Second Merger Class B Shares that are subject to an earnout period, the Sponsor and the GXII Holders also agreed
not to transfer such shares until NioCorp Common Shares achieve a trading price exceeding certain dollar thresholds set forth in the GXII
Support Agreement, subject to the terms and conditions contemplated by the GXII Support Agreement. Such shares will be forfeited if the
NioCorp Common Shares do not achieve the specified trading prices prior to the tenth anniversary of the Closing Date.

of the NioCorp securities issuable in connection with the Transaction, (ii) an amendment to the articles of NioCorp, as amended effective
January 27, 2015, to comply with applicable listing requirements of Nasdaq, and (iii) any other proposals that are necessary to effectuate
