The restricted stock units and stock options owned by Mr. Read were awarded to him in his capacity as an officer and/or director of the Issuer.

Item 4. Purpose of Transaction.

The Reporting Persons purchased the securities of the Issuer based on the Reporting Persons’ belief that the securities, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of securities of the Issuer at prices that would make the purchase or sale of such securities desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of securities of the Issuer on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

In September 2022, upon the closing of the acquisition by the Issuer of Gresham from BitNile, the Issuer agreed to certain arrangements with regard to the composition of the Issuer’s Board of Directors, including the right of BitNile to appoint a majority of the members. Such arrangements are discussed in further detail in Item 6 and are incorporated herein by reference.

Messrs. Horne, Smith, Benz and Read are members of the Board of Directors of the Issuer. Mr. Read is also the Chief Executive Officer of the Issuer.

The Reporting Persons may vote its or his shares or otherwise cause the Issuer to enter into acquisitions and strategic partnerships to expand the business of the Issuer. These acquisitions or strategic partnerships may be funded through the issuance of additional securities of the Issuer, working capital or a combination of both. It is the understanding of the Reporting Persons that one or more of the Reporting Persons have had discussions regarding the possibility of one or more companies affiliated with one or more of the Reporting Persons being acquired by the Issuer in the future.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

On December 27, 2021, the Issuer entered into a Share Exchange Agreement (“Exchange Agreement”) with BitNile and Gresham, which was a wholly owned subsidiary of BitNile. The Exchange Agreement provided that the Company would acquire all of the outstanding shares of capital stock of Gresham from BitNile in exchange for issuing to BitNile 2,920,085 Shares and 514.8 shares of Series F Preferred (the “Exchange Transaction”). Each share of Series F has a stated value of $25,000 and is convertible into such number of the Issuer's common stock equal to the stated value divided by the conversion price of $3.25. If BitNile elected to convert all of its Series F Preferred, it would result in the issuance of 3,960,043 Shares. Completion of the Exchange Transaction was subject to the approval of the Issuer’s shareholders and other customary closing conditions. The Exchange Transaction closed on September 8, 2022. Copies of the Exchange Agreement and the Certificate of Determination of the Series F Preferred are attached as exhibits hereto and are incorporated herein by reference.

On September 8, 2022, the Issuer entered into a Securities Purchase Agreement (“Purchase Agreement”) with BitNile, whereby the Issuer sold to BitNile the Note for $4.25 million. The Note is convertible, at BitNile’s option, at a conversion price of $3.25 per share. If BitNile elected to convert the Note, it would result in the issuance of 1,307,692 Shares. The Note shall automatically convert into common stock upon the earlier of: (i) a public offering of securities in which the Issuer receives net proceeds of at least $25 million (a “Qualified Offering”), in which case the conversion price shall be the price at which the common stock is sold to the public, provided however, that no underwriters' discounts or selling commissions shall be imposed on such conversion price; (ii) a public offering of securities that is not a Qualified Offering, in which case the conversion price shall be the price at which the common stock is sold to the public less a twenty-five percent (25%) discount; or (iii) February 14, 2023, in which case the conversion price shall be the ten-day trailing volume weighted average price of the shares of common stock on such date, less a twenty-five percent (25%) discount. Notwithstanding the foregoing, BitNile may not convert the Note, and the Issuer cannot effect any conversion of the Note in the event that such conversion would result in BitNile beneficially owning shares in excess of the Beneficial Ownership Limitation.

- 13 -

CUSIP No. 375175106

Smith, Jeffrey Bentz and Jonathan Read, who were all appointed effective September 8, 2022. Copies of the Purchase Agreement and Note are attached as exhibits hereto and are incorporated herein by reference.
