Item 3. Source or Amount of Funds or Other Consideration.

On June 24, 2021, THRC Holdings purchased an aggregate of $25,000,000 in principal amount of 16.0% Convertible Senior Secured (Third Lien) PIK Notes of the Issuer (the “Notes”) that are convertible into shares of Common Stock, pursuant to the Note Purchase Agreement dated June 24, 2021 by and among the Issuer, THRC Holdings and the other purchasers party thereto (the “Note Purchase Agreement”). The source of funds for the purchase of the Notes was working capital of THRC Holdings.

On July 1, 2021, THRC Holdings assigned and transferred $12,500,000 of the Notes to Farris Wilks pursuant to a Note Assignment Agreement, by and among THRC Holdings, Farris Wilks and the Issuer (the “Assignment Agreement”) in exchange for $12,500,000.

Item 4. Purpose of Transaction.

On June 24, 2021, the Issuer issued and sold the Notes to THRC Holdings pursuant to the Note Purchase Agreement. Subject to earlier conversion or redemption in accordance with their terms, the Notes will become due and payable on June 5, 2026 (the “Maturity Date”) in a number of shares of Common Stock determined by dividing (i) the outstanding balance of the principal amount of the Notes (together with the accrued but unpaid interest on the Notes) through the date immediately prior to the Maturity Date, by (ii) the volume-weighted average price of the Common Stock for the 20 trading day period (as determined in accordance with the Notes, the “Twenty-Day VWAP”) immediately preceding the Maturity Date. Subject to the terms of the Notes, at any time prior to the payment in full of all outstanding principal and interest owing under the Notes, THRC Holdings may elect to convert all or a portion of such outstanding principal and interest into a number of shares of Common Stock equal to the quotient obtained by dividing (a) the amount of such outstanding aggregate principal amount plus accrued and unpaid interest through the date immediately prior to the date of conversion, by (b) the conversion price, which shall initially be $0.98, and which may be adjusted from time to time as set forth in the Notes.

Following the first anniversary of the Note Purchase Agreement, and at any time in which there are no issued and outstanding shares of Series A Preferred Stock or Series B Preferred Stock, if the Twenty-Day VWAP is greater than $2.00 for ten trading days during any twenty consecutive trading day period, then the Issuer may from time to time, convert all or a portion of the outstanding principal and interest then owing under the Notes into a number of shares of Common Stock at the conversion price set forth above.

In the event of a Change of Control (as defined in the Notes), the Issuer shall have the option to either (i) in full satisfaction of the Notes, pay to THRC Holdings in cash the amount of the outstanding principal and accrued and unpaid interest through the date immediately prior to the date of such Change of Control or (ii) convert no later than the tenth business day following such Change of Control all of the outstanding principal and interest then owing under the Note into a number of shares of Common Stock equal to the quotient obtained by dividing (A) the amount of such outstanding principal and interest through the date immediately prior to the Change of Control, by (B) either (1) the Twenty-Day VWAP immediately preceding such Change of Control or (2) if the Change of Control occurs during any period in which the Common Stock is not listed on any national securities exchange, then the Fair Market Value (as defined in the Notes) of the Common Stock as of the date of the notice of conversion.

Concurrently with the closing of transactions contemplated by the Note Purchase Agreement, THRC Holdings entered into the Registration Rights Agreement, dated June 24, 2021 (the “Registration Rights Agreement”) with the Issuer and certain other stockholders of the Issuer listed on the signature pages thereto. The Registration Rights Agreement includes customary provisions relating to, among other things, “demand” registration rights and “piggy-back” registration rights. Pursuant to the Registration Rights Agreement, the Issuer will have certain obligations to register for resale under the Securities Act of 1933, as amended, all or any portion of the shares of Common Stock that the holders may acquire upon the conversion, exercise or exchange of shares of the Notes.

On July 1, 2021, THRC Holdings assigned and transferred $12,500,000 of the Notes to Farris Wilks pursuant the Assignment Agreement.

The foregoing descriptions of each of the Notes, Note Purchase Agreement, First Amendment to Note Purchase Agreement, Registration Rights Agreement, First Amendment to Registration Rights Agreement, and Assignment Agreement (collectively, the “Agreements”) are qualified in their entirety by reference to each of the Agreements, which are filed as exhibits to the Issuer’s Form 8-K filed with the SEC on June 28, 2021 and are incorporated herein by reference.

The Reporting Persons acquired the securities covered by this Schedule 13D for investment purposes. Depending upon overall market conditions, changes in the Issuer’s operations, business strategy or prospects, other investment opportunities available to the Reporting Persons and the availability of shares of Common Stock at prices that would make the purchase or sale of shares of Common Stock desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of shares of Common Stock in the open market, private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the shares of Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons intend to continue to consider, explore and/or develop plans and may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with the Issuer’s management and board of directors (the “Board”), engaging in discussions with shareholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning changes to the capital allocation strategy, capitalization, ownership structure, strategic transactions, including business combinations, a sale of the Issuer as a whole or in parts or acquisitions or investments by the Issuer, Board structure (including Board composition), operations of the Issuer, purchasing additional shares of Common Stock, selling some or all of their shares of Common Stock, engaging in short selling of or any hedging or similar transaction with respect to the shares of Common Stock, or take any other actions with respect to their investment in the Issuer permitted by law, including any or all of the actions set forth in paragraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons may at any time reconsider and change their plans or proposals relating to the foregoing.

Item 5. Interest in Securities of the Issuer.

(a)—(b) Each Reporting Person’s beneficial ownership of the Common Stock as of the date of this Schedule 13D is reflected on that Reporting Person’s cover page. The Reporting Persons may be deemed to be the beneficial owners of an aggregate of 25,711,113 shares of Common Stock.

THRC Holdings may be deemed to directly beneficially own 12,956,011 shares of Common Stock, representing 12.2% of the issued and outstanding shares of Common Stock, based on (i) 93,377,516 shares of Common Stock outstanding as of June 23, 2021, as represented by the Issuer in the Note Purchase Agreement, plus (ii) 12,755,102 shares of Common Stock issuable to THRC Holdings upon conversion of $12,500,000 in aggregate principal amount of the Notes. THRC Management, as General Partner of THRC Holdings, has exclusive voting and investment power over securities beneficially owned by THRC Holdings, and therefore, may be deemed to share beneficial ownership of such securities. Dan Wilks, as sole Manager of THRC Management, together with his spouse, Staci Wilks, who share the same household, may be deemed to exercise voting and investment power over securities beneficially owned by THRC Holdings, and therefore, Mr. Dan Wilks and Ms. Staci Wilks may each be deemed to share beneficial ownership of such securities.

Farris Wilks may be deemed to directly beneficially own 12,755,102 shares of Common Stock, representing 12.0% of the issued and outstanding shares of Common Stock, based on (i) 93,377,516 shares of Common Stock outstanding as of June 23, 2021, as represented by the Issuer in the Note Purchase Agreement, plus (ii) 12,755,102 shares of Common Stock issuable to Farris Wilks upon conversion of $12,500,000 in aggregate principal amount of the Notes.

(c) The transactions in the shares of Common Stock during the past sixty (60) days are set forth in Schedule I and are incorporated herein by reference.

(d) No person other than the Reporting Persons is known to have the right to receive or the power to direct the receipt of dividends from, or proceeds from the sale of, the shares of Common Stock.

9

(e) Not applicable.

Each of the Reporting Persons may be deemed a member of a “group” with the other Reporting Persons for purposes of Rule 13d-5(b)(1) of the Securities Exchange Act of 1934, as amended, and thus,, may be deemed the beneficial owner of the shares of Common Stock directly owned by the other Reporting Persons. Each Reporting Person specifically disclaims beneficial ownership of securities reported herein that it does not directly own or control except to the extent of his or her or its pecuniary interest therein.

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

On June 25, 2021, THRC Holdings, the Issuer and the other parties thereto entered into a First Amendment to the Note Purchase Agreement with AG Energy Funding, LLC (“AG”) pursuant to which the Issuer sold an additional $38,000,000 in aggregate principal amount of Notes to AG Energy Funding, LLC (“AG”). In connection therewith, on June 25, 2021, the parties to the Registration Rights Agreement entered into an amendment thereto in order to join AG as a party to the Registration Rights Agreement and increase the number of “Registrable Securities” thereunder to include additional shares of Common Stock issued or issuable upon conversion of the then outstanding Notes and any Notes that may be issued in the future.

On July 1, 2021, THRC Holdings assigned and transferred $12,500,000 of the Notes to Farris Wilks pursuant the Assignment Agreement.

On July 6, 2021, the Reporting Persons entered into a Joint Filing Agreement in which, among other things, the Reporting Persons agreed to the joint filing on behalf of each of them of statements on Schedule 13D with respect to securities of the Issuer.
