Business Combination Agreement and Plan of Reorganization

On February 14, 2023, Nabors Energy Transition Corp. (“NETC”), Vast Solar Pty Ltd, an Australian proprietary company limited by shares (“Vast”), NEPTUNE MERGER SUB, INC., a Delaware corporation and wholly owned subsidiary of Vast (“Merger Sub”), Nabors Energy Transition Sponsor LLC, a Delaware limited liability company (“NETC Sponsor”), and Nabors Industries Ltd. (“Nabors”) entered into a Business Combination Agreement (the “Business Combination Agreement,” and the transactions contemplated thereby, the “Business Combination”), pursuant to which, among other things and subject to the terms and conditions contained therein, Merger Sub will merge with and into NETC (the “Merger”), with NETC continuing as the surviving corporation (the “Surviving Corporation”) and a wholly owned direct subsidiary of Vast.

Immediately prior to the Merger, the MEP Share Conversion (as defined below), the Existing Convertible Note Conversion (as defined below) and a conversion of ordinary shares in Vast (the “Vast Ordinary Shares”) (whether by way of subdivision or consolidation) (the “Vast Split Adjustment”) will be undertaken whereby the amount of all Vast Ordinary Shares outstanding immediately after such corporate actions will be 20,500,000 (subject to certain adjustments) to be effective at the effective time of the Merger (the “Effective Time”).

Exchange and Conversion of Securities

At or around the time of undertaking the Vast Split Adjustment and the Existing Convertible Note Conversion, Vast will cause each share or other awards granted under Vast’s existing Management Equity Plan Deed (such shares and awards, the “MEP Shares”) that is outstanding immediately prior to such time to be settled by the conversion of those MEP Shares into Vast Ordinary Shares (the “MEP Share Conversion”).

At the Effective Time, by virtue of the Merger and without any action on the part of NETC, Vast, Merger Sub or any of the holders of any of their securities, the following events will take place simultaneously:

Each share of NETC Class A Common Stock issued and outstanding immediately prior to the Effective Time with respect to which a NETC stockholder has validly exercised its redemption rights (“Redemption Rights”) provided for in NETC’s amended and restated certificate of incorporation (the “NETC Charter”) (i) will be redeemed immediately prior to the Effective Time (such shares, the “Redemption Shares”) and will be converted into the right to receive from NETC, in cash, an amount per share calculated in accordance with such stockholder’s Redemption Rights and (ii) will not be entitled to receive the Per Share Merger Consideration.

In the event that the NETC Class A Common Stock and NETC Warrants comprising a single unit of NETC sold in NETC’s initial public offering of units (the “NETC IPO” and such units the “NETC Units”) have not been detached so as to permit separate transferability or trading prior to the Effective Time, then effective immediately prior to the Effective Time, any and all NETC Units will be automatically detached and broken out into their constituent parts, such that a holder of one NETC Unit will hold one share of NETC Class A Common Stock and one-half of one NETC Warrant, and the underlying NETC Class A Common Stock and NETC Warrants will be converted in accordance with the Business Combination Agreement. However, if the detachment would result in a holder of a NETC Warrant, sold as part of the NETC Units in the NETC IPO holding a fractional NETC Warrant, then prior to the conversion the number of NETC Warrants deemed to be held by such holder will be rounded down to the nearest whole number.

Earn-Out

During the period between the date that is seventy (70) days after the closing of the Business Combination (the “Closing,” and such date, the “Closing Date”) and the five-year anniversary of the Closing Date (the “Earnout Period”), Vast will issue to eligible Vast shareholders up to 2,799,999 additional Vast Ordinary Shares in the aggregate (the “Earnout Shares”), consisting of (i) up to 1,299,999 additional Vast Ordinary Shares in the aggregate issued (a) upon satisfaction of certain share price targets set forth in the Business Combination Agreement, which price targets will be based upon the daily volume-weighted average closing sale price of one Vast Ordinary Share quoted on the New York Stock Exchange (the “NYSE”) (or the exchange on which the Vast Ordinary Shares are then listed), for any twenty (20) trading days within any thirty (30) consecutive trading day period within the Earnout Period or (b) upon a Change of Control (as defined in the Business Combination Agreement) pursuant to which Vast or its shareholders has the right to receive consideration implying a value per Vast Ordinary Share equal to or above the share price targets set forth in the Business Combination Agreement, and (ii) 1,500,000 additional Vast Ordinary Shares issued upon the achievement of certain project milestones or upon a Change of Control.

While Vast must use its reasonable best efforts to do all things necessary (including obtaining any shareholder or other approvals required under applicable Laws, including the Australian Corporations Act 2001 (Cth) (the “Corporations Act”)) to issue Earnout Shares, if certain Earnout Shares cannot be issued within three (3) months of an entitlement to them arising or if an issue of Earnout Shares is subsequently unwound by order of a court or other governmental authority, Vast must instead pay an amount of cash to the affected eligible Vast shareholder in an amount up to the value of the unissued Earnout Shares as defined in accordance with the Business Combination Agreement.

Representations, Warranties and Covenants

The Business Combination Agreement contains customary representations, warranties and covenants of (a) NETC and (b) Vast and Merger Sub relating to, among other things, their ability to enter into the Business Combination Agreement and their outstanding capitalization.

Conditions to Closing

The obligations of NETC, Merger Sub and Vast to consummate the Business Combination are subject to the satisfaction or waiver (where permissible) at or prior to the Closing of each of the following mutual conditions:

The obligations of NETC to consummate the Business Combination are subject to the satisfaction or waiver (where permissible) at or prior to the Closing of the following additional conditions:

The obligations of Vast and Merger Sub to consummate the Business Combination are subject to the satisfaction or waiver (where permissible) at or prior to the Closing of the following additional conditions:

Termination

The Business Combination Agreement may be terminated, and the Business Combination may be abandoned at any time prior to the Effective Time, notwithstanding any requisite approval and adoption of the Business Combination Agreement and the Business Combination by the stockholders of NETC, as follows:

Effect of Termination

If the Business Combination Agreement is terminated, the Business Combination Agreement will become void and there will be no liability under the Business Combination Agreement on the part of any party, except in the case of a willful material breach of the Business Combination Agreement prior to such termination.

A copy of the Business Combination Agreement is filed with this Current Report on Form 8-K as Exhibit 2.1 and is incorporated herein by reference. The foregoing description of the Business Combination Agreement is qualified in its entirety by reference to the full text of the Business Combination Agreement filed with this Current Report on Form 8-K. The Business Combination Agreement is included to provide security holders with information regarding its terms. It is not intended to provide any other factual information about Vast, NETC or Merger Sub. In particular, the assertions embodied in representations and warranties by Vast, NETC and Merger Sub 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, security holders should not rely on the representations and warranties in the Business Combination Agreement as characterizations of the actual state of facts about Vast, NETC or Merger Sub.

Support Agreement

Concurrently with the signing of the Business Combination Agreement, NETC, NETC Sponsor, Vast, Nabors Lux and NETC’s independent directors (together with NETC Sponsor and Nabors Lux, the “Insiders”) entered into the Support Agreement (the “Support Agreement”) pursuant to which, among other things, the Insiders agreed to (i) certain restrictions on the transfer of Founder Shares and NETC Warrants, (ii) vote all Founder Shares held by them in favor of the adoption and approval of the Business Combination Agreement, (iii) waive the anti-dilution rights set forth in the NETC Charter with respect to their Founder Shares and (iv) enter into the Shareholder and Registration Rights Agreement, and NETC Sponsor will have the right to be issued up to 3,900,000 additional Vast Ordinary Shares during the Earnout Period upon satisfaction of certain price targets set forth therein, which price targets will be based on the daily volume-weighted average closing sale price of one Vast Ordinary Share quoted on the NYSE (or the exchange on which the Vast Ordinary Shares are then listed), for any twenty (20) trading days within any thirty (30) consecutive trading day period within the Earnout Period.

The foregoing description of the Support Agreement is qualified in its entirety by reference to the full text of the Support Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K, and incorporated herein by reference.

Shareholder and Registration Rights Agreement

Concurrently with the Closing, NETC, Vast, NETC Sponsor, Nabors Lux and the other holder parties thereto will enter into a shareholder and registration rights agreement (the “Shareholder and Registration Rights Agreement”), pursuant to which Vast will agree that, within sixty days of the Closing, Vast will file with the SEC (at Vast’s sole cost and expense) a resale registration statement, and Vast will use its commercially reasonable efforts to have the such registration statement declared effective as soon as reasonably practicable after the filing thereof. In certain circumstances, the holders of certain securities held by or issuable to certain existing shareholders of NETC and Vast can demand Vast’s assistance with underwritten offerings and exercise demand or piggyback rights with respect to such offerings. Additionally the Shareholder and Registration Rights Agreement contains a customary lock-up agreement for six months after the Closing. The Shareholder and Registration Rights Agreement grants to NETC Sponsor the right to nominate for election one director to Vast’s board of directors (the “Vast Board”) for so long as NETC Sponsor and its affiliates collectively beneficially own 50% of the number of Vast Ordinary Shares that NETC Sponsor and its affiliates collectively beneficially owned immediately following the Closing. The Shareholder and Registration Rights Agreement also grants to AgCentral (as defined below) the rights to nominate for election one director to the Vast Board for so long as AgCentral and its affiliates collectively beneficially own at least the number of Vast Ordinary Shares that entitle NETC Sponsor to nominate for election one director.

The information in this Item 7.01, including Exhibits 99.1, 99.2 and 99.3, is furnished and shall not be deemed to be filed for purposes of Section 18 of the Exchange Act, or otherwise be subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any filing under the Securities Act or the Exchange Act, regardless of any general incorporation language in such filings.

Subscription Agreements

Concurrently with the signing of the Business Combination Agreement, Nabors Lux and AgCentral Energy Pty Limited (“AgCentral”) entered into subscription agreements (the “Notes Subscription Agreements,” and the financing received therefrom, the “Interim Company Financing”), pursuant to which, among other things, Nabors Lux and AgCentral have each agreed to subscribe for and purchase up to $5.0 million (or $10.0 million in aggregate principal amount) of Senior Convertible Notes from Vast in a private placement to be funded in accordance with the Notes Subscription Agreements. Any amount of Interim Company Financing provided by Nabors Lux or AgCentral will be exchanged for an equivalent number of Vast Ordinary Shares immediately prior to the Effective Time and be deemed to reduce their subscription amounts under the PIPE Financing. Vast may enter into additional Notes Subscription Agreements with additional investors between the signing of the Business Combination Agreement and the Closing (the financing received under such additional agreements and together with the financing received under the Notes Subscription Agreements, the “Convertible Financing”).

Also concurrently with the signing of the Business Combination Agreement, Nabors Lux and AgCentral entered into subscription agreements with Vast (the “Equity Subscription Agreements”), pursuant to which, among other things, Nabors Lux and AgCentral agreed, subject to the Closing occurring and certain other conditions, to subscribe for and purchase, and Vast agreed to issue and sell to each of Nabors Lux and AgCentral, up to $15.0 million (or an aggregate of $30.0 million) of Vast Ordinary Shares for $10.20 per share in a private placement.

The foregoing description of the Equity Subscription Agreements and the Notes Subscription Agreements is qualified in their entirety by reference to the full text of the form of Equity Subscription Agreements and the form of Notes Subscription Agreements, copies of which are filed as Exhibit 99.4 and Exhibit 99.5, respectively, to this Current Report on Form 8-K, and incorporated herein by reference.

Extension

Pursuant to the NETC Charter, NETC Sponsor (or its affiliates or designees) may deposit into the Trust Account $2,760,000, which represents $0.10 per unit sold in the NETC IPO, to extend the date NETC has to consummate its initial business combination by an additional three months, up to two times. If NETC completes its initial business combination, it will, at the option of NETC Sponsor, repay such loaned amounts out of the proceeds of the Trust Account or convert a portion or all of the total loan amount into NETC Warrants at a price of $1.00 per warrant, which warrants will be identical to the warrants issued in a private placement at the time of the NETC IPO.

NETC Sponsor or its affiliates expect to deposit $2,760,000 (the “Extension Amount”) into the Trust Account prior to February 18, 2023 to extend the date by which NETC has to consummate its initial business combination from February 18, 2023 to May 18, 2023. Pursuant to the Business Combination Agreement, if the Minimum Cash Condition is not satisfied and all other conditions to Closing are satisfied or waived, NETC Sponsor will accept, or cause any affiliate depositing the Extension Amount to accept, NETC Warrants in repayment of the Extension Amount up to the amount necessary to satisfy the Minimum Cash Condition.
