Investor Agreement

On February 24, 2021, in connection with the entering into of the Purchase Agreement, the Issuer, Grove Energy, SK Holdings and SK E&S entered into an Investor Agreement (the “Investor Agreement”) providing for certain rights and restrictions relating to the investment by the Purchasers.

Board Representation. The Investor Agreement provides that Grove Energy will be entitled to designate one person (the “SK Designee”) to be appointed to the Issuer’s Board. The SK Designee was appointed to the Board effective as of the closing of the Transaction (the ‘Closing”) for a term expiring at the Issuer’s 2023 annual meeting of stockholders. Grove Energy will have the right to require the Board to nominate a SK Designee for election to the Board by the stockholders of the Issuer at subsequent annual stockholder meetings until the earliest of (i) the date on which Grove Energy and affiliates beneficially own less than 4.0% of the issued and outstanding Common Stock, (ii) the second anniversary of the Closing in the event that the parties to the JV Agreement have not entered into a definitive joint venture agreement with respect to the Proposed Asia JV (the “Definitive Asia JV Agreement”), and (iii) any expiration or termination of the Definitive Asia JV Agreement (the “Director Period”).

Standstill Obligations. The Investor Agreement provides that Grove Energy, SK Holdings, SK E&S and their respective affiliates (“SK Parties”) are subject to a standstill provision until the later of (i) the expiration of the Director Period, (ii) the second anniversary of the Closing, and (iii) the date on which Grove Energy and affiliates beneficially own less than 5.0% of the issued and outstanding Common Stock (the “Standstill Period”). During the Standstill Period, the SK Parties will not, among other things and subject to specified exceptions: (a) acquire any securities of the Issuer (except for purchases of Common Stock in the public market to the extent necessary to reverse any decrease in such parties’ percentage ownership of the issued and outstanding Common Stock resulting solely from a net increase in the number of shares of issued and outstanding Common Stock); (b) propose any merger, consolidation, business combination, tender offer or similar transaction involving the Issuer; (c) solicit proxies or consents to vote any securities of the Issuer; (d) form, join or participate in any group (as such term is used in the rules of the Securities and Exchange Commission (the “SEC”)); or (e) seek to call a meeting of the stockholders of the Issuer or propose any matter to be voted upon by the stockholders of the Issuer.

Transfer Restrictions. The Investor Agreement also provides that, for a period ending on the second anniversary of the Closing, the SK Parties will be prohibited from transferring any Common Stock. If immediately following the second anniversary of the Closing, either (i) the Director Period remains in effect or (ii) the Definitive Asia JV Agreement has been executed and remains in effect, then, until the third anniversary of the Closing, the SK Parties may transfer a number of shares of Common Stock not exceeding, in the aggregate in any 90-day period, 2.0% of the issued and outstanding shares of Common Stock as of the first date in such 90-day period. If immediately following the second anniversary of the Closing, both (i) the Director Period has ended and (ii) the Definitive Asia JV Agreement has not been executed or otherwise is not in effect, then the SK Parties may transfer any amount of Common Stock. From and after the third anniversary of the Closing, the SK Parties may transfer any amount of Common Stock. The SK Parties will also be generally prohibited from transferring Common Stock to (a) any competitor of the Issuer (as determined by the Board) or (b) any person that together with its affiliates would, after giving effect to such transfer, beneficially own 5.0% or more of the issued and outstanding Common Stock.

Voting Obligations. The Investor Agreement also provides that, during the Standstill Period, Grove Energy will vote all of its shares of Common Stock (i) for all Board-recommended director nominees and (ii) on each other matter brought to a vote of the Issuer’s stockholders, in accordance with the recommendation of the Board on such matter. Under the Investor Agreement, Grove Energy has granted a proxy to the Issuer to vote all such shares of Common Stock in the event that it does not vote such shares at least ten (10) days prior to the date of any meeting of stockholders.

Registration Rights. The Investor Agreement includes customary resale shelf registration rights for Grove Energy that require the Issuer to register the Common Stock held by Grove Energy for resale.

The description of the Investor Agreement in this Item 6 are not intended to be complete and are qualified in their entirety by reference to such documents, which are filed as exhibits hereto and incorporated by reference herein.
