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.”

1

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.

Representations, Warranties and Covenants

The Business Combination Agreement contains customary representations, warranties and covenants of (i) GXII and (ii) NioCorp and Merger Sub, relating to, among other things, their respective abilities and authority to enter into the Business Combination Agreement and their respective capitalization.

Registration Rights Agreement and Lock-Up

Pursuant to the Business Combination Agreement, in connection with the Closing, GXII, GX Sponsor II LLC, in its capacity as a shareholder of GXII (the “Sponsor”), the directors 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.

In addition, the Registration Rights Agreement will provide that the Sponsor and the NioCorp Holders will be subject to “lock-up” restrictions on transfer of NioCorp securities held by them after the Closing for the period beginning on the Closing Date and ending on the earlier of (i) one year after the Closing and (ii) subsequent to the Closing, (a) the date on which the volume-weighted average price of the NioCorp Common Shares on the principal 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.

3

Termination

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 final, non-appealable Order of a Governmental Entity of competent jurisdiction (provided, however, that the right to terminate the Business Combination Agreement under the clause described in this clause (ii) will not be available to a party whose breach of any provision of 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 Meeting; (vi) by NioCorp if GXII breaches any representation, warranty or covenant made by it in the Business Combination Agreement such that the conditions regarding the truth, completeness and correctness of the representations and warranties made by GXII and the performance 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 and correctness of the representations and warranties made by NioCorp and the performance by NioCorp and Merger Sub of their covenants 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 Business Combination Agreement is included to provide investors and security holders with information regarding its terms.

On September 25, 2022, concurrently with the execution of the Business Combination Agreement, GXII, NioCorp, the Sponsor, and the GXII Holders entered into a support agreement (the “GXII Support Agreement”), pursuant to which the Sponsor and the GXII Holders agreed, among other things, to vote in favor of (i) an amendment 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.

In addition, any statements that refer to projections (including Averaged EBITDA, Averaged EBITDA Margin and After-Tax Cumulative Net Free Cash Flow), forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements.

The forward-looking statements are based on the current expectations of the management of NioCorp and GXII, 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.

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 GXII 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 GXII Class A Shares being greater than expected, which may reduce the cash in trust available to NioCorp upon the consummation of the business combination; 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 GXII following announcement of the Business Combination Agreement and the transactions contemplated therein; the inability to complete the proposed transactions due to, among other things, the failure to obtain NioCorp shareholder approval or GXII shareholder approval or the execution of definitive agreements relating to the convertible debenture transaction and the stand by equity purchase facility contemplated by the term sheets with Yorkville; the risk that the announcement and consummation of the proposed transactions disrupts NioCorp’s current plans; the ability to recognize the anticipated benefits of the proposed transactions; unexpected costs related to the proposed transactions; the risks that the consummation of the proposed transactions is substantially delayed or does not occur, including prior to the date on which GXII is required to liquidate under the terms of its charter documents; NioCorp’s ability to operate as a going concern; NioCorp’s requirement of significant additional capital; NioCorp’s limited operating history; NioCorp’s history of losses; cost increases for NioCorp’s exploration and, if warranted, development projects; a disruption in, or failure of, NioCorp’s information technology systems, including those related to cybersecurity; equipment and supply shortages; current and future offtake agreements, joint ventures, and partnerships; NioCorp’s ability to attract qualified management; the effects of the COVID-19 pandemic or other global health crises on NioCorp’s business plans, financial condition and liquidity; estimates of mineral resources and reserves; mineral exploration 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 GXII 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 herein and attributable to NioCorp, GXII or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to herein.
