Pursuant to the Purchase Agreement, and upon the terms and subject to the conditions described therein, Issuer completed the purchase of substantially all of the Breckenridge assets related to seismic data acquisition services other than its multi-client data library (the “Assets”), in exchange for a combination of equity consideration and a convertible note (the “Transaction”). The consideration delivered by Issuer to Wilks for the Assets consisted of the following equity consideration and convertible note (collectively, the “Consideration”):

 

●

Equity Consideration. Issuer delivered to Wilks the aggregate amount of 1,188,235 newly-issued shares of common stock of Issuer.

 

 

●

Convertible Note. Issuer delivered to Wilks a convertible promissory note (the “Convertible Note”) in the principal amount of $9,880,000.50 payable on or after June 30, 2024 that, upon the terms and subject to the conditions described therein, will automatically convert into 5,811,765 newly-issued shares of Common Stock of Issuer (the “Conversion Shares”) at a conversion price of $1.70 per share (which price is equal to the market price of common stock of Issuer at closing of the Transaction), subject to adjustment as described in the Convertible Note, after Issuer receives stockholder approval of the proposal to issue the Conversion Shares upon conversion of the Convertible Note in accordance with Listing Rule 5635 of the NASDAQ Listed Company Manual.

 

On March 24, 2023 and in connection with the Purchase Agreement, the Company and Wilks entered in to a Voting Agreement (the “Voting Agreement”) pursuant to which Wilks agreed to, at any shareholder meeting held to approve the Transaction, vote the shares beneficially owned by Wilks in favor of (a) the approval of the Transaction, (b) the approval of any proposal to adjourn or postpone any shareholder meeting to a later date if there are not sufficient votes for the approval of the Transaction on the date on which such meeting is held, and (c) any other matter necessary for consummation of the transactions contemplated by the Purchase Agreement or any other document related to the Transaction which is considered at any such meeting or is the subject of any such consent solicitation.

 

The Reporting Persons intend to review their investment in the Issuer on a continuing basis in anticipation of the closing of the Transactions, and may purchase additional shares of Common Stock.

 

The foregoing descriptions of the Purchase Agreement, the Convertible Note, and the Voting Agreement are qualified in their entirety by reference to the full text of the Purchase Agreement, the Convertible Note, and the Voting Agreement, which are filed as Exhibit 1, Exhibit 2, and Exhibit 3 to this Amendment, respectively, and are incorporated by reference herein.
