Beneficial Owners

If you hold shares in an account with a brokerage firm, bank, or other nominee, then you are a beneficial owner with respect to these shares and hold such shares in “street name.” If you are a beneficial owner of shares on the record date, the brokerage firm, bank, or other nominee (the “intermediary”) will provide instructions detailing how to direct the voting of your shares through the intermediary. The intermediary that holds your shares is considered the holder of record for purposes of voting at the Annual Meeting.

As a beneficial owner, you are also invited to attend the Annual Meeting. However, since you are not the holder of record, you may not vote your shares in person at the Annual Meeting unless you obtain a signed proxy from the intermediary giving you the right to vote the shares.

As such, for bothto vote on Proposal 1 and Proposal 3 to be voted onthrough an intermediary at the Annual Meeting, you must provide timely instructions on how the intermediary should vote your shares. When an intermediary does not have discretion to vote on a particular matter, you have not given timely instructions on how the intermediary should vote your shares, and the intermediary indicates it does not have authority to vote such shares on its proxy, a “brokernon-vote” results. Although any brokernon-vote wouldwill be counted as present at the Annual Meeting for purposes of determining a quorum, it would be treated as not entitled to vote with respect tonon-discretionary matters. As such, brokernon-votes will not be counted as a vote “FOR” or “AGAINSTWITHHOLD” Proposal 1 and will be counted as a vote “AGAINST” Proposal 3.1.

The ratification of the appointment of ourthe Company’s independent registered public accounting firm for the year ending December 31, 20182019 (Proposal 2) is a discretionary matter on which intermediaries may vote in the absence of timely instructions from you.

CORPORATE GOVERNANCE MATTERS

Board of Directors and Terms of Office of Directors

The Company’s amended and restated certificate of incorporation provides for the classification of the Board into three separate classes, with each class serving a three-year term. WeThe Company currently havehas seven directors, with each Class I director having a term that expires at the Annual Meeting, each Class II director having a term that expires at the Company’s annual meeting of stockholders in 2019 andAnnual Meeting, each Class III director having a term that expires at the Company’s annual meeting of stockholders in 2020 and each Class I director having a term that expires at the Company’s annual meeting of stockholders in 2021, or in each case until their respective successors are duly elected and qualified, or until their earlier resignation, removal or death.

The Board consists of two individuals (Messrs. TownsendKovalik and Kovalik)Ebner) serving as Class I directors, two individuals (Messrs. Quarls and Contino) serving as Class II directors and three individuals (Messrs. Rosenberg, Mayer and Hanna) serving as Class III directors.

Independence of Directors

Because Tema and KLR Energy Sponsor, LLC (“KLR Sponsor”) control a majority of the combined voting power of all classes of ourthe Company’s outstanding voting stock, we arethe Company is a “controlled company” under NASDAQ corporate governance listing standards. Under the NASDAQ rules, a company of which more than 50% of the voting power is held by another person or group of persons acting together is a controlled company and may elect not to comply with certain NASDAQ corporate governance requirements, including the requirements that:

If in the future Tema and KLR Sponsor cease to control a majority of the combined voting power of all classes of ourthe Company’s outstanding voting stock, wethe Company will no longer be a “controlled company” within the meaning of the rules of NASDAQ. Under NASDAQ rules, a company that ceases to be a controlled company must comply with the independent board committee requirements as they relate to the nominating and corporate governance and compensation committees on the followingphase-in schedule: (1) one independent committee member at the time it ceases to be a controlled company, (2) a majority of independent committee members within 90 days of the date it ceases to be a controlled company and (3) all independent committee members within one year of the date it ceases to be a controlled company. Additionally, NASDAQ rules provide a12-monthphase-in period from the date a company ceases to be a controlled company to comply with the majority independent board requirement. During thesephase-in periods, ourthe Company’s stockholders will not have the same protections afforded to stockholders of companies of which the majority of directors are independent. Additionally, if, within thephase-in periods, we arethe Company is not able to recruit additional directors who would qualify as independent, or otherwise comply with NASDAQ rules, wethe Company may be subject to enforcement actions by NASDAQ. Furthermore, a change in our Board and committee membership may result in a change in corporate strategy and operation philosophies, and may result in deviations from ourthe Company’s current growth strategy.

Pursuant to NASDAQ Rule 5605(a), the Board is required to determine whether any director has a relationship which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. The Board has determined that Messrs. Contino, Mayer, Quarls and Rosenberg are independent within the meaning of NASDAQ Rule 5605(a). In addition, the Board has determined that Messrs. Contino, Mayer and Quarls are independent within the meaning of NASDAQ Rule IM5605-4 and Rule10A-3 under the Exchange Act.

Board Leadership Structure and Role in Risk Oversight

The Board has no policy with respect to the separation of the offices of Chairman and Chief Executive Officer. The Board believes that this issue is part of the succession planning process and that it is in the best interests of the Company for the Board to make a determination regarding this issue each time it elects a new Chief Executive Officer.

Currently, ourUpon Mr. French joining the Company as Chief Executive Officer, the Company’s Chief Executive Officer and Chairman positions are separated. The Board believes that the separation of these roles maximizes management’s efficiency and furthers ourthe Company’s ongoing efforts to maintain strong corporate governance and assure stockholder representation and the independent, objective and effective oversight of management. Separating these positions allows ourthe Company’s Chief Executive Officer to focus on ourtheday-to-day business of the Company, while allowing the Chairman to lead the Board in its fundamental role of providing guidance to and oversight of management. Mr. French has not been appointed to the Board as of the date of this proxy statement, but it is expected that he will be appointed to the Board as a Class I director on a future date.

The Board is actively involved in overseeing ourthe Company’s risk management processes. The Board focuses on ourthe Company’s general risk management strategy and ensures that appropriate risk mitigation strategies are implemented by management. Further, operational and strategic presentations by management to the Board include consideration of the challenges and risks of ourthe Company’s businesses, and the Board and management actively engage in discussion on these topics. In addition, each of the Board’s committees considers risk within its area of responsibility. For example, ourthe audit committee provides oversight to legal and compliance matters and assesses the adequacy of ourthe Company’s risk-related internal controls. OurThe compensation committee considers risk and structures ourthe Company’s executive compensation programs, if any, to provide incentives to reward appropriately executives for growth without undue risk taking.

Executive Sessions of Independent Directors

The independent directors of the Board hold regularly scheduled meetings in executive session. The purpose of these executive sessions is to promote open and candid discussion among the independent directors. The director who presides at these meetings (the “Lead Director”) is chosen by the Board, based on the recommendation of the Nominating and Governance Committee. The Lead Director is responsible for preparing an agenda for the meetings of the independent directors in executive session. OurThe Chairman acts as Lead Director at these meetings.

Committees of the Board of Directors

The standing committees of the Company’s Board consist of an audit committee (the “Audit Committee”), a compensation committee (the “Compensation Committee”) and a nominating and governance committee (the “Nominating and Governance Committee”). Each of the committees reports to the Board.

The composition, duties and responsibilities of these committees are set forth below.

Audit Committee

The principal functions of the Company’s Audit Committee are detailed in the Company’s Audit Committee charter, which is available on the Company’s website, and include:

The Compensation Committee is delegated all authority of the Board as may be required or advisable to fulfill its purposes. The Compensation Committee may delegate to any subcommittee it may form, the responsibility and authority for any particular matter, as it deems appropriate from time to time under the circumstances. Meetings may, at the discretion of the Compensation Committee, include members of management, other members of the Board, consultants or advisors, and such other persons as the Compensation Committee believes to be necessary or appropriate. The Compensation Committee will consult with ourthe Company’s Chief Executive Officer when evaluating the performance of, and setting the compensation for, ourthe Company’s executive officers other than the Chief Executive Officer. In 2017, the Company engaged Michele Steckbeck of Steckbeck Consulting to serve as a compensation advisor to our director of human resources.

The Compensation Committee may, in its sole discretion, retain and determine funding for legal counsel, compensation consultants, as well as other experts and advisors (collectively, “Committee Advisors”), including the authority to retain, approve the fees payable to, amend the engagement with and terminate any Committee Advisor, as it deems necessary or appropriate to fulfill its responsibilities.

In 2017,2018, the Compensation Committee engaged Longnecker & Associates (“L&A”) directly as its independent compensation consultant to assist the committee with its responsibilities related to ourthe Company’s executive officer and director compensation programs. A representative of L&A attends Compensation Committee meetings, as requested, and communicates with the chair of the Compensation Committee between meetings. However, L&A provides no services for management or the Compensation Committee that are unrelated to the duties and responsibilities of the Compensation Committee and the Compensation Committee makes all decisions regarding the compensation of ourthe Company’s executive officers and directors. L&A reports directly to the Compensation Committee and all work conducted by L&A for usthe Company is on behalf of the committee.

The Compensation Committee regularly reviews the services provided by its outside consultant and believes that L&A is independent under applicable SEC rules in providing executive compensation consulting services. In making this determination, the committee noted that during fiscal 2017:2018:

The Compensation Committee continues to monitor the independence of L&A on a periodic basis.

Nominating and Governance Committee

The principal functions of the Company’s Nominating and Governance Committee are detailed in the Company’s Nominating and Governance Committee charter, which is available on the Company’s website, and include:

The Nominating and Governance Committee also develops and recommends to the Board corporate governance principles and practices and assists in implementing them, including conducting a regular review of ourthe Company’s corporate governance principles and practices. The Nominating and Governance Committee oversees the annual performance evaluation of the Board and the committees of the Board and makes a report to the Board on succession planning.

OurThe Nominating and Governance Committee consists of Messrs. Rosenberg, ContinoQuarls, Kovalik and Kovalik,Ebner, with Mr. Rosenberg serving as the Chair. With the exception of Mr. Kovalik, all members of the CompensationNominating and Governance Committee are independent under NASDAQ Rule 5605(a).

We haveThe Company has no minimum qualifications for director candidates.

Prior to recommending to the Board that an existing director be nominated for election as a director at the annual meeting of stockholders, the Nominating and Governance Committee will consider and review the director’s:

In the event that a vacancy on the Board arises, the Nominating and Governance Committee will seek and identify a qualified director nominee to be recommended to the Board for either appointment by the Board to serve the remainder of the term of the director position that is vacant or election at the next annual meeting of stockholders. To identify such a nominee, the Nominating and Governance Committee will solicit recommendations from existing directors and senior management. These recommendations will be considered by the Nominating and

Governance Committee along with any recommendations that have been received from stockholders as discussed below. The Nominating and Governance Committee may, in its discretion, retain a search firm to provide additional candidates. Prior to recommending to the Board that a person be elected to fill a vacancy on the Board, the Nominating and Governance Committee will consider and review the candidate’s:

Although we dothe Company does not have a policy in regard to the consideration of diversity in identifying director nominees, the Board seeks nominees with distinct professional backgrounds, experience and perspectives so that the Board as a whole has the range of skills and viewpoints necessary to fulfill its responsibilities.

Nominations by Stockholders

The Nominating and Governance Committee will treat recommendations for directors that are received from the Company’s stockholders equally with recommendations received from any other source; provided, however, that in order for such stockholder recommendations to be considered, the recommendations must comply with the procedures set forth in ourthe Company’s bylaws.
