INFORMATION ABOUT THIS PROXY STATEMENT

Why you received this proxy statement. You are viewing or have received these proxy materials because the Board is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the Securities and Exchange Commission (“SEC”) and that is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, Lonestar is making this proxy statement and its 2017 Annual Report available to its stockholders electronically via the Internet. On or about April 10, 2018, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this proxy statement and our 2017 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2017 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Internet Notice.

This delivery method is referred to as “householding” and can result in significant cost savings.

We agree to deliver promptly, upon written or oral request, a separate copy of the Internet Notice or proxy materials, as requested, to any stockholder at the

Questions and Answers about the 2018 Annual Meeting of Stockholders

WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?

The Record Date for the Annual Meeting is March 29, 2018. You are entitled to vote at the Annual Meeting only if you were a stockholder of record at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. Each outstanding share of Class A Common Stock is entitled to one vote for all matters before the Annual Meeting. The holder of SeriesA-1 Preferred Stock will vote together as a single class with the holders of Class A Common Stock on all matters before the Annual Meeting. The holder of SeriesA-1 Preferred Stock will be entitled to the number of votes equal to the number of shares of Class A Common Stock that such holder would hold on anas-converted basis on the Record Date. As of the Record Date, there were (i) 24,634,313 shares of Class A Common Stock outstanding, and (ii) 85,857 shares of SeriesA-1 Preferred Stock outstanding, which are convertible into 14,309,500 shares of Class A Common Stock, for a total of 38,943,813 shares of Class A Common Stock (including the SeriesA-1 Preferred Stock on anas-converted basis) entitled to vote at the Annual Meeting.

WHAT IS THE DIFFERENCE BETWEEN BEING A “RECORD HOLDER” AND HOLDING SHARES IN “STREET NAME”?

A record holder holds shares in his or her name. Shares held in “street name” means shares that are held in the name of a bank or broker on a person’s behalf.

AM I ENTITLED TO VOTE IF MY SHARES ARE HELD IN “STREET NAME”?

Yes. If your shares are held by a bank or a brokerage firm, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in street name, these proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. If your shares are held in street name, you may not vote your shares in person at the Annual Meeting, unless you obtain a legal proxy from your bank or brokerage firm.

HOW MANY SHARES MUST BE PRESENT TO HOLD THE ANNUAL MEETING?

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, in person or by proxy, of the holders of the Company’s Class A Common Stock and, on anas-converted basis, SeriesA-1 Preferred Stock, representing a majority in voting power of all of the shares of stock entitled to vote at the meeting, will constitute a quorum.

WHO CAN ATTEND THE 2018 ANNUAL MEETING OF STOCKHOLDERS?

You may attend the Annual Meeting only if you are a Lonestar Stockholder who is entitled to vote at the Annual Meeting, or if you hold a valid proxy for the Annual Meeting. If you would like to attend the Annual Meeting, you must call1-817-921-1889 no later than 5:00 p.m. Central Time on May 22, 2018 to have your name placed on the attendance list. In order to be admitted into the Annual Meeting, your name must appear on the attendance list and you must present government-issued photo identification (such as a driver’s license). If your bank or broker holds your shares in street name, you will also be required to present proof of beneficial ownership of our Class A Common Stock on the Record Date, such as the Internet Notice you received from your bank or broker, or a bank or brokerage statement or a letter from your bank or broker showing that you owned shares of our Class A Common Stock at the close of business on the Record Date.

WHAT IF A QUORUM IS NOT PRESENT AT THE ANNUAL MEETING?

If a quorum is not present at the scheduled time of the Annual Meeting, the Chairperson of the Annual Meeting may adjourn the Annual Meeting to another place, if any, date, or time.

QUESTIONS AND ANSWERS ABOUT THE 2017 ANNUAL MEETING OF STOCKHOLDERS

WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE INTERNET NOTICE OR MORE THAN ONE SET OF PROXY MATERIALS?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

HOW DO I VOTE?

We recommend that stockholders vote by proxy even if they plan to attend the Annual Meeting and vote in person. If you are a stockholder of record, there are three ways to vote by proxy:

• by Telephone—You can vote by telephone by calling1-800-579-1639 and following the instructions on the proxy card;

• by Internet—You can vote over the Internet atwww.proxyvote.com by following the instructions on the Internet Notice or proxy card; or

• by Mail—You can vote by mail by signing, dating and mailing the proxy card, which you may have received by mail.

Telephone and Internet voting facilities for stockholders of record will be available 24 hours a day and will close at 1:00 a.m., Central Time, on May 24, 2018.

If your shares are held in street name through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Telephone and Internet voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares in person at the Annual Meeting, you should contact your bank or broker to obtain a legal proxy and bring it to the Annual Meeting in order to vote.

CAN I CHANGE MY VOTE AFTER I SUBMIT MY PROXY?

Yes.

If you are a registered stockholder, you may revoke your proxy and change your vote:

• by submitting a duly executed proxy bearing a later date;

• by granting a subsequent proxy through the Internet or telephone;

• by giving written notice of revocation to the Secretary of Lonestar prior to or at the Annual Meeting; or

• by voting in person at the Annual Meeting.

Your most recent proxy card or telephone or Internet proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Secretary before your proxy is voted or you vote in person at the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote in person at the Annual Meeting by obtaining a legal proxy from your bank or broker and submitting the legal proxy along with your ballot.

QUESTIONS AND ANSWERS ABOUT THE 2017 ANNUAL MEETING OF STOCKHOLDERS

WHO WILL COUNT THE VOTES?

A representative of Broadridge Financial Solutions, Inc., our inspector of election, will tabulate and certify the votes.

WHAT IF I DO NOT SPECIFY HOW MY SHARES ARE TO BE VOTED?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 2 of this proxy statement, as well as with the description of each proposal in this proxy statement.

WILL ANY OTHER BUSINESS BE CONDUCTED AT THE ANNUAL MEETING?

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

HOW MANY VOTES ARE REQUIRED FOR THE APPROVAL OF THE PROPOSALS TO BE VOTED UPON AND HOW WILL ABSTENTIONS AND BROKERNON-VOTES BE TREATED?

Proposal	Votes required	Effect of Votes Abstentions and BrokerNon-Votes
Proposal 1: Election of Directors	A director nominee will be elected to the Board if the votes of the Company’s Class A Common Stock and SeriesA-1 Preferred Stock, voting together as a single class and with the SeriesA-1 Preferred Stock voting on anas-converted basis, cast “FOR” the nominee exceed the votes cast “AGAINST” the nominee.	Abstentions and brokernon-votes will have no effect.
Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm	The favorable vote of a majority of the votes cast affirmatively or negatively by holders of the Company’s shares of Class A Common Stock and SeriesA-1 Preferred Stock, voting together as a single class and with the SeriesA-1 Preferred Stock voting on anas-converted basis.	Abstentions will have no effect. We do not expect any brokernon-votes on this proposal.
Proposal 3: Amendment of our Amended and Restated 2016 Incentive Plan to increase the number of shares available for issuance under such plan	The favorable vote of a majority of the votes cast affirmatively or negatively by holders of the Company’s shares of Class A Common Stock and SeriesA-1 Preferred Stock, voting together as a single class and with the SeriesA-1 Preferred Stock voting on anas-converted basis.	Abstentions and brokernon-votes will have no effect.

QUESTIONS AND ANSWERS ABOUT THE 2017 ANNUAL MEETING OF STOCKHOLDERS

WHAT IS AN ABSTENTION AND HOW WILL ABSTENTIONS BE TREATED?

An “Abstention” represents a stockholder’s affirmative choice to decline to vote on a proposal. Abstentions are counted as present and entitled to vote for purposes of determining a quorum. Abstentions are not considered to be votes cast and, accordingly, will have no effect on the vote for Proposals 1, 2 and 3.

WHAT ARE BROKERNON-VOTES AND DO THEY COUNT FOR DETERMINING A QUORUM?

Generally, brokernon-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of BDO USA, LLP, as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner onnon-routine matters, such as the election of directors. Brokernon-votes count for purposes of determining whether a quorum is present.

WHERE CAN I FIND THE VOTING RESULTS OF THE 2018 ANNUAL MEETING OF STOCKHOLDERS?

We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report onForm 8-K, which we intend to file with the SEC after the Annual Meeting.

PROPOSALS TO BE VOTED ON—PROPOSAL 1

Election of Directors

At the Annual Meeting, ten (10) directors are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2018 and until such director’s successor is duly elected and qualified or until such director’s earlier death, resignation or removal.

We currently have ten (10) directors on our Board. Our current directors are Frank D. Bracken, III, who has served on our Board since January 2012, Henry B. Ellis, who has served on our Board since October 2016, Daniel R. Lockwood, who has served on our Board since May 2014, John H. Murray, who has served on our Board since October 2016, Matthew B. Ockwood, who has served on our Board since November 2017, Stephen H. Oglesby, who has served on our Board since March 2017, Phillip Z. Pace, who has served on our Board since June 2017, John H. Pinkerton, who has served on our Board since March 2015, Dr. Christopher Rowland, who has served on our Board since January 2013 and Randy L. Wolsey, who has served on our Board since January 2017. The Board has nominated ten directors for election as directors at the Annual Meeting.

Our Bylaws provide that the authorized number of directors may be changed by action of the Board or the stockholders. Under the Board Representation Agreement further discussed below in “Corporate Governance—Board Composition”, subject to certain share-ownership requirements, EF Realisation Company Limited (“EF Realisation”) has the right to designate a limited number of nominees for election to the Board of Directors. EF Realisation currently has the right to designate up to two nominees and has designated Dr. Christopher Rowland and John H. Murray for election to our Board. In addition, subject to certain share-ownership requirements, Chambers Energy Capital III, LP (“Chambers”) has the right to designate a limited number of nominees for election to the Board of Directors. Chambers currently has the right to designate up to two nominees and has designated Matthew B. Ockwood and Phillip Z. Pace for election to our Board.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of Class A Common Stock or SeriesA-1 Preferred Stock represented thereby for the election as directors of the persons whose names and biographies appear below. All of the persons whose names and biographies appear below are currently serving as our directors. In the event any of the nominees should become unable to serve, or for good cause will not serve, as a director, it is intended that votes will be cast for a substitute nominee designated by the Board or the Board may elect to reduce its size. The Board has no reason to believe that the nominees named below will be unable to serve if elected. Each of the nominees has consented to being named in this proxy statement and to serve if elected.

VOTE REQUIRED

A Director nominee will be elected to the Board if the votes of the Company’s Class A Common Stock and SeriesA-1 Preferred Stock, voting together as a single class and with the SeriesA-1 Preferred Stock voting on anas-converted basis, cast “FOR” the nominee exceed the votes cast “AGAINST” the nominee. If any nominee for director receives a greater number of votes “AGAINST” his or her election than votes “FOR” such election, our Bylaws require that such person tender his resignation to the Board. Abstentions and brokernon-votes are not considered votes cast for the foregoing purpose and will have no effect on the election of Director nominees.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors unanimously recommends a vote FOR the election of the ten director nominees named below.

PROPOSAL 2

Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit and Risk Committee has appointed BDO USA, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of BDO USA, LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

BDO USA, LLP also served as our independent registered public accounting firm for the fiscal year ended December 31, 2017. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit andnon-audit related services. A representative of BDO USA, LLP is expected to attend the Annual Meeting and to have an opportunity to make a statement and be available to respond to appropriate questions from stockholders.

In the event that the appointment of BDO USA, LLP is not ratified by the stockholders, the Audit and Risk Committee will consider this fact when it appoints the independent auditors for the fiscal year ending December 31, 2019. Even if the appointment of BDO USA, LLP is ratified, the Audit and Risk Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interests of the Company.

VOTE REQUIRED

This proposal requires the favorable vote of a majority of the votes cast affirmatively or negatively by holders of the Company’s outstanding shares of Class A Common Stock and SeriesA-1 Preferred Stock, voting together as a single class and with the SeriesA-1 Preferred Stock voting on anas-converted basis. Abstentions are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of BDO USA, LLP we do not expect any brokernon-votes in connection with this proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors unanimously recommends a vote FOR the ratification of the appointment of BDO USA, LLP as our independent registered public accounting firm.

Report of the Audit and Risk Committee of the Board of Directors

The Audit and Risk Committee has reviewed the Company’s audited financial statements for the fiscal year ended December 31, 2017 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit and Risk Committee has also received from, and discussed with, the Company’s independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit and Risk Committee, including the matters required to be discussed by statement on Auditing Standard No. 1301, as adopted by the Public Company Accounting Oversight Board (“PCAOB”).

The Company’s independent registered public accounting firm also provided the Audit and Risk Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit and Risk Committee concerning independence. In addition, the Audit and Risk Committee discussed with the independent registered public accounting firm its independence from the Company.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit and Risk Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form10-K for the fiscal year ended December 31, 2017.

AUDIT AND RISK COMMITTEEPRE-APPROVAL POLICY AND PROCEDURES

The Audit and Risk Committee has adopted a policy (the“Pre-Approval Policy”) which sets forth the procedures and conditions pursuant to which audit andnon-audit services proposed to be performed by the independent auditor may bepre-approved. ThePre-Approval Policy generally provides that we will not engage BDO USA, LLP to render any audit, audit-related, tax or permissiblenon-audit service unless the service is either (i) explicitly approved by the Audit and Risk Committee (“specificpre-approval”) or (ii) entered into pursuant to thepre-approval policies and procedures described in thePre-Approval Policy (“generalpre-approval”). Unless a type of service to be provided by BDO USA, LLP has received generalpre-approval under thePre-Approval Policy, it requires specificpre-approval by the Audit and Risk Committee or by a designated member of the Audit and Risk Committee to whom the committee has delegated the authority to grantpre-approvals. Any proposed services exceedingpre-approved cost levels or budgeted amounts will also require specificpre-approval. For both types ofpre-approval, the Audit and Risk Committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The Audit and Risk Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. On an annual basis, the Audit and Risk Committee reviews and generallypre-approves the services (and related fee levels or budgeted amounts) that may be provided by BDO USA, LLP without first obtaining specificpre-approval from the Audit and Risk Committee. The Audit and Risk Committee may revise the list of generalpre-approved services from time to time, based on subsequent determinations.

PROPOSAL 3

Amendment of our Amended and Restated 2016 Incentive Plan to Increase the Number of Shares Available for Issuance Under Such Plan

The Company’s Amended and Restated 2016 Incentive Plan (the “A&R 2016 Plan”) was adopted and approved by a majority in interest of our stockholders on May 24, 2017. The A&R 2016 Plan, as approved in May 2017, provides for the grant of stock options, stock appreciation rights, restricted stock, dividend equivalents, restricted stock units and other stock or cash-based awards to our employees, consultants and directors up to an aggregate of 2,200,000 shares of our Class A Common Stock. The A&R 2016 Plan is described in more detail below.

The A&R 2016 Plan reserved a number of shares for issuance that we expected to be sufficient for grants previously made under the plan and for grants to be made through the 2018 calendar year. We anticipated that approval of additional shares for grants to be made in the future would be necessary and we are now seeking that approval.

In this proposal, we are asking our stockholders to approve an amendment to the A&R 2016 Plan to increase the number of shares of our Class A Common Stock available for issuance thereunder by 800,000 shares (the “Plan Amendment”), such that a total of 3,000,000 shares of our Class A Common Stock would be authorized for issuance under the A&R 2016 Plan. The Board approved the Plan Amendment in 2018, subject to approval by our stockholders at this meeting. A copy of the A&R 2016 Plan, as proposed to be amended, is attached to this proxy statement as Exhibit A.

The A&R 2016 Plan is not being amended in any respect, other than to increase the number of shares authorized for issuance thereunder and to eliminate certain obsolete provisions contained therein that were previously intended to allow certain awards granted under the A&R 2016 Plan to satisfy an exemption for performance-based compensation from the deductibility limitation under Section 162(m) of the Code. Tax reform legislation in 2017 eliminated the availability of this exemption and we have therefore eliminated the corresponding provisions in the A&R 2016 Plan. These eliminated provisions include a provision that limited awards that could be granted to any individual participant in any one year to the following amounts: (i) options or stock appreciation rights were previously limited to 750,000 shares; (ii) other awards that were denominated in shares and that were intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code were previously limited to 500,000 shares; and (iii) awards denominated in cash were previously limited to $5,000,000. If the Plan Amendment is approved, these limits will no longer apply.

If the Plan Amendment is not approved by our stockholders, it will not become effective. In such event, the A&R 2016 Plan will remain in effect in the form approved in May 2017 and we will continue to make grants thereunder to the extent shares remain or again become available.

VOTE REQUIRED

This proposal requires the favorable vote of a majority of the votes cast affirmatively or negatively by holders of the Company’s outstanding shares of Class A Common Stock and SeriesA-1 Preferred Stock, voting together as a single class and with the SeriesA-1 Preferred Stock voting on anas-converted basis. Abstentions and brokernon-votes are not considered to be votes cast for the foregoing purpose, and, accordingly, will have no effect on the outcome of the vote on this proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors unanimously recommends a vote FOR the Plan Amendment to increase the number of shares of our Class A Common Stock available for issuance under the A&R 2016 Plan.

15

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

PURPOSE AND BACKGROUND FOR THE DETERMINATION OF ADDITIONAL SHARES

The purpose of the A&R 2016 Plan is to enhance the Company’s ability to attract, retain and motivate persons who make (or are expected to make) important contributions to the Company by providing these individuals with equity ownership and other incentive opportunities. We believe that the A&R 2016 Plan is essential to our success. Equity awards are intended to motivate high levels of performance, align the interests of our employees, directors, and consultants with those of our stockholders by giving these individuals the perspective of an owner with an equity stake in our Company and provide a means of recognizing their contributions to the success of our Company. Our Board and our leadership team believe that long-term equity incentive awards are necessary to remain competitive in the market and are essential to recruiting and retaining the highly qualified employees who help our Company meet its goals.

In its determination to approve the Plan Amendment, the Board considered a number of factors, including a review of our historical grant practices, anticipated future equity grant needs, burn rate, dilution and overhang metrics, peer group market practices and trends and the costs of the A&R 2016 Plan, as proposed to be amended, including shareholder value transfer cost. Specifically, we considered:

• As of December 31, 2017, a total of 781,091 shares remained available for issuance under the A&R 2016 Plan. This represented approximately 2% of our outstanding shares (on a fully diluted basis). As of the Record Date, there were 933,625 shares remaining available for issuance under the A&R 2016 Plan.

• Following grants made in early 2018, we had nearly exhausted the number of shares available for issuance under the A&R 2016 Plan and did not have shares available to make any additional meaningful awards to any executives or key employees. Therefore, if additional shares are not approved, we will lose an important compensation tool aligned with shareholder interests to attract, motivate and retain highly qualified talent.

• The total aggregate equity value of the 800,000 additional authorized shares being requested under the A&R 2016 Plan, based on the closing price for our Class A Common Stock on December 29, 2017 of $3.97 per share is $3,176,000.

• As of December 31, 2017, our end of year overhang rate, calculated by dividing (i) the number of shares subject to equity awards outstanding at the end of the fiscal year plus the number of shares remaining available for issuance under the A&R 2016 Plan by (ii) the number of Company shares outstanding at the end of the fiscal year on a fully diluted basis (including outstanding warrants), was approximately 5.6%. If approved, the issuance of the additional shares to be reserved under the A&R 2016 Plan would dilute the holdings of shareholders by an additional 1.8% on a fully diluted basis, based on the number of shares of our Class A Common Stock outstanding as of December 31, 2017. If the Plan Amendment is approved, we expect our overhang at the end of fiscal year 2017 will be approximately 7.4% on a fully diluted basis (including the shares that will be reserved for issuance under the A&R 2016 Plan). We believe this amount would be appropriate in light of market competitive levels, taking into account our current circumstances as outlined above.

KEY FEATURES OF THE A&R 2016 PLAN

The A&R 2016 Plan contains a number of features that we believe are consistent with good practices in equity compensation and which we believe protect our shareholders’ interests with respect to the awards that we have granted and expect to grant under the plan. These features include:

• Without shareholder approval, the A&R 2016 Plan prohibits any alteration or amendment that operates to increase the total number of shares of that may be issued under the plan (other than adjustments in connection with certain corporate reorganizations and other events) or to change the designation or class of persons eligible to receive awards under the plan.

16

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

• The A&R 2016 Plan does not have single-trigger accelerated vesting provision for change in control.

• Awards may not be repriced, replaced or regranted through cancellation or modification without shareholder approval if the effect would be to reduce the exercise price for the shares under the award.

• A grant-date fair value limit of $500,000 per year will apply to awards tonon-employee directors. Additional annual award limits will also apply for other participants. For additional information, see the discussion below under “Description of the A&R 2016 Plan—Award Limits.”

ADDITIONAL INFORMATION ABOUT THE A&R 2016 PLAN

As of December 31, 2017, there were 728,909 Restricted Stock Units and 690,000 Stock Appreciation Rights outstanding under the A&R 2016 Plan (taking into account the forfeiture of stock options that expired unexercised on such date). Our Stock Appreciation Rights had a weighted average exercise price of $7.20 and weighted average remaining years to expiration of 4.15 years. The closing price of our Class A Common Stock as of March 29, 2018 was $4.34. The terms and conditions of all future awards under the A&R 2016 Plan will be determined by the Administrator in its discretion.

DESCRIPTION OF THE A&R 2016 PLAN

The following sets forth a description of the material features and terms of the A&R 2016 Plan, as proposed to be amended. The following summary is qualified in its entirety by reference to the full text of the A&R 2016 Plan, as amended, which is attached hereto as Exhibit A.

Authorized Shares; Share Counting Provisions

If approved, an aggregate of 3,000,000 shares of Class A Common Stock will be reserved for issuance under the A&R 2016 Plan. All such shares of Class A Common Stock reserved for issuance may be issued under the A&R 2016 Plan upon the exercise of incentive stock options. Shares issued under the A&R 2016 Plan may be authorized but unissued shares, shares purchased on the open market or treasury shares.

If an award under the A&R 2016 Plan (including an award granted under the 2016 Plan prior to the Restatement) expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, canceled without having been fully exercised or forfeited, in any case, in a manner that results in the Company acquiring shares covered by the award at a price not greater than the price (as adjusted to reflect any equity restructuring) paid by the participant for the shares or not issuing any shares covered by the award, the unused shares covered by the award will again be available for award grants under the A&R 2016 Plan. In addition, shares delivered to the Company to satisfy the exercise or purchase price of an award and/or to satisfy tax withholding obligation (including shares retained by the Company from the award being exercised or purchased and/or creating the tax obligation) will again be available for award grants under the A&R 2016 Plan. Dividend equivalents paid in cash will not be counted against the number of shares reserved under the A&R 2016 Plan.

Awards granted under the A&R 2016 Plan in substitution for any options or other stock or stock-based awards granted by an entity before the entity’s merger or consolidation with us or our acquisition of the entity’s property or stock will not reduce the shares available for grant under the A&R 2016 Plan, but will count against the maximum number of shares that may be issued upon the exercise of incentive stock options.

Administration

The A&R 2016 Plan is administered by our Board, which may delegate its duties and responsibilities to one or more committees of our directors and/or officers (referred to collectively as the plan administrator), subject to the

17

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

limitations imposed under the A&R 2016 Plan, Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), stock exchange rules and other applicable laws. The plan administrator has the authority to take all actions and make all determinations under the A&R 2016 Plan, to interpret the A&R 2016 Plan and award agreements and to adopt, amend and repeal rules for the administration of the A&R 2016 Plan as it deems advisable. The plan administrator also has the authority to determine which eligible service providers receive awards, grant awards and set the terms and conditions of all awards under the A&R 2016 Plan, including any vesting and vesting acceleration provisions, subject to the conditions and limitations in the A&R 2016 Plan.

Award Limits

The maximum aggregate grant date fair value, as determined in accordance with FASB ASC Topic 718 (or any successor thereto), of all equity and cash-based awards granted to anon-employee director for services as a director under the A&R 2016 Plan during any fiscal year may not exceed $500,000 per year (or $1,000,000 in the fiscal year of a director’s initial service).

Eligibility

Employees, consultants andnon-employee directors of the Company or any of its subsidiaries will be eligible to receive awards under the A&R 2016 Plan. As of December 31, 2017, approximately 59 employees and 9non-employee directors were eligible to receive awards under the 2016 Plan.

Types of Awards

The A&R 2016 Plan provides for the grant of stock options, including incentive stock options and nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, and other stock or cash-based awards. Awards to eligible individuals shall be subject to the terms of an individual award agreement between the Company and the individual. A brief description of each award type follows.

• Stock Options. Stock options may be granted under the A&R 2016 Plan, including both incentive stock options andnon-qualified stock options, which provide the holder a right to purchase shares of Class A Common Stock at a specified exercise price. The exercise price per share for each stock option will be set by the plan administrator, but will not be less than the fair market value on the date of the grant (or 110% of the price of an incentive stock option in the case of an individual who, on the date of the grant, owns or is deemed to own shares representing more than 10% of the stock of the Company). The term of any option award may not be longer than ten years (or five years in the case of an incentive stock option granted to a 10% stockholder of the Company). The plan administrator will determine the time period for exercise of each award, including the time period for exercise following a termination of service by the recipient, subject to theten-year limitation.

• Stock Appreciation Rights. The plan administrator is authorized to grant stock appreciation rights (“SARs”) to eligible recipients in its discretion, on such terms and conditions as it may determine, consistent with the A&R 2016 Plan. A stock appreciation right entitles the holder to exercise the stock appreciation right to acquire shares of the Company’s Class A Common Stock upon exercise within a specified time period from the date of the grant. Subject to the provisions of the stock appreciation right award agreement, the recipient may receive from the Company an amount determined by multiplying the difference between the price per share of the stock appreciation right and the value of the share on the date of exercise by the number of shares of Class A Common Stock subject to the award. The maximum term for which stock appreciation rights may be exercisable under the A&R 2016 Plan is ten years.

• Restricted Stock. The plan administrator may make awards of restricted stock to eligible individuals in such amounts and at purchase prices to be established by the plan administrator in connection with

18

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

each award. Such awards will be subject to restrictions and other terms and conditions as are established by the plan administrator. Upon issuance of restricted stock, recipients generally have the rights of a stockholder with respect to such shares, subject to the limitations and restrictions established by the plan administrator in the individual award agreement. Such rights generally include the right to receive dividends and other distributions in relation to the award.

• Restricted Stock Units. The A&R 2016 Plan authorizes awards of restricted stock units to eligible individuals in amounts and at purchase prices and upon such other terms and conditions as are established by the plan administrator for each award. Restricted stock unit awards entitle recipients to acquire shares of the Company’s Class A Common Stock in the future under certain conditions. Holders of restricted stock units generally have no rights of ownership or as stockholders in relation to the award, unless and until the restrictions lapse and the restricted stock unit award vests in accordance with the terms of the grant. Restricted stock units may be accompanied by the right to receive the equivalent value of dividends paid on shares of the Company’s Class A Common Stock prior to the delivery of the underlying shares (i.e., dividend equivalent rights). The plan administrator may provide that settlement of restricted stock units will occur upon or as soon as reasonably practicable after the restricted stock units vest or will instead be deferred, on a mandatory basis or at the participant’s election, in a manner intended to comply with Section 409A of the Code.

• Other Stock or Cash Based Awards. Other stock or cash-based awards are awards of cash, fully vested shares of the Company’s Class A Common Stock and other awards valued wholly or partially by referring to, or otherwise based on, shares of the Company’s Class A Common Stock. Other stock or cash-based awards may be granted to participants and may also be available as a payment form in the settlement of other awards, as standalone payments and as payment in lieu of compensation otherwise payable to any individual who is eligible to receive awards. The plan administrator will determine the terms and conditions of other stock or cash-based awards, including any purchase price, performance goals (which may be based on performance criteria), transfer restrictions and vesting conditions.

Performance-Based Awards

For purposes of the A&R 2016 Plan, one or more performance criteria may be used in setting performance goals applicable to stock or cash based awards, which performance criteria may include but will not be limited to: net earnings (either before or after interest, taxes, depreciation and amortization), sales or revenue, net income (either before or after taxes), operating earnings, cash flow (including, but not limited to, operating cash flow and free cash flow), return on net assets, return on stockholders’ equity, return on assets, return on capital, return on sales, gross or net profit margin, expenses or expense levels, total shareholder return, internal rate of return (“IRR”), financial ratios (including those measuring liquidity, activity, profitability or leverage), working capital, earnings per share, price per share, market capitalization, any GAAP financial performance measures, inventory management, measures related to A&R balance and write-offs, timeliness and/or accuracy of business reporting, approval or implementation of strategic plans, financing and other capital raising transactions, debt levels or reductions, cash levels, acquisition activity, investment sourcing activity, marketing initiatives, projects or processes, achievement of customer satisfaction objectives, net asset value, net asset value per share, capital expenditures, net borrowing, debt leverage levels, credit quality or debt ratings, economic value added, individual business objectives, growth in production, added reserves, growth in reserves, inventory growth, environmental health and safety performance, effectiveness of hedging programs, improvements in internal controls and policies, and retention and recruitment of employees, any of which may be measured in absolute terms or as compared to any incremental increase or decrease. Such performance goals also may be based solely by reference to the Company’s performance or the performance of a subsidiary, division, business segment or business unit of the Company or a subsidiary or based upon performance relative to performance of other companies or upon comparisons of any performance indicators relative to performance of other companies. The

19

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

A&R 2016 Plan also permits the plan administrator to provide for objectively determinable adjustments to the applicable performance criteria in setting such performance goals.

Prohibition on Repricing

Under the A&R 2016 Plan, the plan administrator may not, without the approval of the Company’s stockholders, authorize the repricing of any outstanding option or stock appreciation right to reduce its price per share, cancel any option or stock appreciation right in exchange for cash or another award when the price per share exceeds the fair market value of the underlying shares, or take any other action with respect to an option or stock appreciation right that the Company determines would be treated as a repricing under the rules and regulations of the principal U.S. stock exchange on which the shares of Class A Common Stock are listed.

Certain Transactions

The plan administrator has broad discretion to take action under the A&R 2016 Plan, as well as make adjustments to the terms and conditions of existing and future awards, to prevent the dilution or enlargement of intended benefits and facilitate necessary or desirable changes in the event of certain transactions and events affecting the Company’s Class A Common Stock, such as dividends or other distributions (whether in the form of cash, Class A Common Stock, other securities, or other property), reorganizations, mergers, consolidations, change in control events and other corporate transactions. In addition, in the event of certainnon-reciprocal transactions with the Company’s stockholders known as “equity restructurings,” the plan administrator will make equitable adjustments to outstanding awards. No adjustment or other action will be authorized for awards that are intended to qualify as QPBC, which would cause such awards to fail to continue to qualify as QPBC, unless the plan administrator determines that the award should not so qualify. Notwithstanding the preceding section, in the event of a change in control in which outstanding awards are not continued, converted, assumed or replaced by the Company or the successor to the Company in the change in control, such awards shall become fully exercisable and all forfeiture, repurchase and other restrictions on such awards shall lapse immediately prior to the change in control.

Amendment and Termination

The plan administrator may amend, suspend or terminate the A&R 2016 Plan at any time; however, no amendment, other than an amendment that increases the number of shares available under the A&R 2016 Plan, may materially and adversely affect an award outstanding under the A&R 2016 Plan without the consent of the affected participant. Our Board is required to obtain stockholder approval for any amendment to the A&R 2016 Plan to the extent necessary to comply with applicable laws. The A&R 2016 Plan will remain in effect until March 22, 2026, unless earlier terminated by our Board. No awards may be granted under the A&R 2016 Plan after its termination.

Forfeiture and Claw-backs

All awards (including any proceeds, gains or other economic benefit obtained in connection with any award) made under the A&R 2016 Plan are subject to any claw-back policy implemented by the Company, including any claw-back policy adopted to comply with the requirements of applicable law (including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder) as set forth in such claw-back policy or award agreement.

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following summary is based on an analysis of the Code as currently in effect, existing laws, judicial decisions, administrative rulings, regulations and proposed regulations, all of which are subject to change.

20

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

Moreover, the following is only a summary of United States federal income tax consequences. Actual tax consequences to participants may be either more or less favorable than those described below depending on the participant’s particular circumstances.

Incentive Stock Options. No income will be recognized by a participant for United States federal income tax purposes upon the grant or exercise of an incentive stock option. The basis of shares transferred to a participant upon exercise of an incentive stock option is the price paid for the shares. If the participant holds the shares for at least one year after the transfer of the shares to the participant and two years after the grant of the option, the participant will recognize capital gain or loss upon sale of the shares received upon exercise equal to the difference between the amount realized on the sale and the basis of the stock. Generally, if the shares are not held for that period, the participant will recognize ordinary income upon disposition in an amount equal to the excess of the fair market value of the shares on the date of exercise over the amount paid for the shares, or if less (and if the disposition is a transaction in which loss, if any, will be recognized), the gain on disposition. Any additional gain realized by the participant upon the disposition will be a capital gain. The excess of the fair market value of shares received upon the exercise of an incentive stock option over the option price for the shares is an item of adjustment for the participant for purposes of the alternative minimum tax. Therefore, although no income is recognized upon exercise of an incentive stock option, a participant may be subject to alternative minimum tax as a result of the exercise.

Non-qualified Stock Options. No income is expected to be recognized by a participant for United States federal income tax purposes upon the grant of anon-qualified stock option. Upon exercise of anon-qualified stock option, the participant will recognize ordinary income in an amount equal to the excess of the fair market value of the shares on the date of exercise over the amount paid for the shares. Income recognized upon the exercise of anon-qualified stock option will be considered compensation subject to withholding at the time the income is recognized, and, therefore, the participant’s employer must make the necessary arrangements with the participant to ensure that the amount of the tax required to be withheld is available for payment.Non-qualified stock options are designed to provide the employer with a deduction equal to the amount of ordinary income recognized by the participant at the time of the recognition by the participant, subject to the deduction limitations described below.

Stock Appreciation Rights. There is expected to be no United States federal income tax consequences to either the participant or the employer upon the grant of SARs. Generally, the participant will recognize ordinary income subject to withholding upon the receipt of payment pursuant to SARs in an amount equal to the aggregate amount of cash and the fair market value of any Class A Common Stock received. Subject to the deduction limitations described below, the employer generally will be entitled to a corresponding tax deduction equal to the amount includible in the participant’s income.

Restricted Stock. If the restrictions on an award of shares of restricted stock are of a nature that the shares are both subject to a substantial risk of forfeiture and are not freely transferable (within the meaning of Section 83 of the Code), the participant will not recognize income for United States federal income tax purposes at the time of the award unless the participant affirmatively elects to include the fair market value of the shares of restricted stock on the date of the award, less any amount paid for the shares, in gross income for the year of the award pursuant to Section 83(b) of the Code. In the absence of this election, the participant will be required to include in income for United States federal income tax purposes on the date the shares either become freely transferable or are no longer subject to a substantial risk of forfeiture (within the meaning of Section 83 of the Code), the fair market value of the shares of restricted stock on such date, less any amount paid for the shares. The employer will be entitled to a deduction at the time of income recognition to the participant in an amount equal to the amount the participant is required to include in income with respect to the shares, subject to the deduction limitations described below. If a Section 83(b) election is made within 30 days after the date the restricted stock is received, the participant will recognize ordinary income at the time of the receipt of the restricted stock, and the employer will be entitled to a corresponding deduction, equal to the fair market value of the shares at the

21

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

time, less the amount paid, if any, by the participant for the restricted stock. If a Section 83(b) election is made, no additional income will be recognized by the participant upon the lapse of restrictions on the restricted stock, but, if the restricted stock is subsequently forfeited, the participant may not deduct the income that was recognized pursuant to the Section 83(b) election at the time of the receipt of the restricted stock.

Dividends paid to a participant holding restricted stock before the expiration of the restriction period will be additional compensation taxable as ordinary income to the participant subject to withholding, unless the participant made an election under Section 83(b). Subject to the deduction limitations described below, the employer generally will be entitled to a corresponding tax deduction equal to the dividends includible in the participant’s income as compensation. If the participant has made a Section 83(b) election, the dividends will be dividend income, rather than additional compensation, to the participant.

If the restrictions on an award of restricted stock are not of a nature that the shares are both subject to a substantial risk of forfeiture and not freely transferable, within the meaning of Section 83 of the Code, the participant will recognize ordinary income for United States federal income tax purposes at the time of the transfer of the shares in an amount equal to the fair market value of the shares of restricted stock on the date of the transfer, less any amount paid therefore. The employer will be entitled to a deduction at that time in an amount equal to the amount the participant is required to include in income with respect to the shares, subject to the deduction limitations described below.

Restricted Stock Units. There will be no United States federal income tax consequences to either the participant or the employer upon the grant of restricted stock units. Generally, the participant will recognize ordinary income subject to withholding upon the receipt of cash and/or transfer of shares of Class A Common Stock in payment of the restricted stock units in an amount equal to the aggregate of the cash received and the fair market value of the shares of Class A Common Stock so transferred. Subject to the deduction limitations described below, the employer generally will be entitled to a corresponding tax deduction equal to the amount includible in the participant’s income.

Generally, a participant will recognize ordinary income subject to withholding upon the payment of any dividend equivalents paid with respect to an award in an amount equal to the cash the participant receives. Subject to the deduction limitations described below, the employer generally will be entitled to a corresponding tax deduction equal to the amount includible in the participant’s income.

Limitations on the Employer’s Compensation Deduction. Section 162(m) of the Code limits the deduction certain employers may take for otherwise deductible compensation payable to certain executive officers of the employer to the extent the compensation paid to such an officer for the year exceeds $1 million.

Excess Parachute Payments. Section 280G of the Code limits the deduction that the employer may take for otherwise deductible compensation payable to certain individuals if the compensation constitutes an “excess parachute payment.” Excess parachute payments arise from payments made to disqualified individuals that are in the nature of compensation and are contingent on changes in ownership or control of the employer or certain affiliates. Accelerated vesting or payment of awards under the A&R 2016 Plan upon a change in ownership or control of the employer or its affiliates could result in excess parachute payments. In addition to the deduction limitation applicable to the employer, a disqualified individual receiving an excess parachute payment is subject to a 20% excise tax on the amount thereof.

Application of Section 409A of the Code. Section 409A of the Code imposes an additional 20% tax and interest on an individual receivingnon-qualified deferred compensation under a plan that fails to satisfy certain requirements. For purposes of Section 409A,“non-qualified deferred compensation” includes equity-based incentive programs, including some stock options, stock appreciation rights and restricted stock unit programs.

22

PROPOSAL 3—INCENTIVE PLAN AMENDMENT

Generally speaking, Section 409A does not apply to incentive stock options,non-discountednon-qualified stock options and stock appreciation rights if no deferral is provided beyond exercise, or restricted stock.

The awards made pursuant to the A&R 2016 Plan are expected to be designed in a manner intended to comply with the requirements of Section 409A of the Code to the extent the awards granted under the A&R 2016 Plan are not exempt from coverage. However, if the A&R 2016 Plan fails to comply with Section 409A in operation, a participant could be subject to the additional taxes and interest.

State and local tax consequences may in some cases differ from the federal tax consequences. The foregoing summary of the United States federal income tax consequences in respect of the A&R 2016 Plan is for general information only. Interested parties should consult their own advisors as to specific tax consequences of their awards.

The A&R 2016 Plan is not subject to the Employee Retirement Income Security Act of 1974, as amended, and is not intended to be qualified under Section 401(a) of the Code.

PLAN BENEFITS

The benefits or amounts that may be received or allocated to participants under the A&R 2016 Plan will be determined at the discretion of the plan administrator and are not currently determinable. The following table sets forth the outstanding restricted stock awards and stock appreciation rights that each of the groups identified in the table above held as of December 31, 2017 under the A&R 2016 Plan.

Corporate Governance

GENERAL

The Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics and charters for our Nominating and Corporate Governance Committee, Audit and Risk Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Business Conduct and Ethics in the “Governance” section of the “Shareholder Information” page of our website located at www.lonestarresources.com, or by writing to our Secretary at our offices at 111 Boland Street, Suite 300, Fort Worth, Texas, 76107.

BOARD COMPOSITION

Our Board currently consists of ten members: Frank D. Bracken, III, Henry B. Ellis, Daniel R. Lockwood, John H. Murray, Matthew B. Ockwood, Stephen H. Oglesby, Phillip Z. Pace, John H. Pinkerton, Dr. Christopher Rowland and Randy L. Wolsey. As set forth in our Bylaws, each of our directors is elected to serve from the time of election and qualification until the next annual meeting following such election and until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal.

On October 26, 2016, we entered into a Board Representation Agreement with EF Realisation (the “Board Representation Agreement”). Under the Board Representation Agreement, for as long as EF Realisation owns 15% or more of the issued and outstanding shares of our Class A Common Stock, it has the right to nominate up to, but no more than, two directors (each, a “Designee”) to serve on the Board and for as long as EF Realisation owns at least 10% but less than 15% of our issued and outstanding shares of Class A Common Stock, it has the right to nominate up to, but no more than, one director to serve on the Board. EF Realisation currently has the right to designate two nominees and has designated Christopher Rowland and John H. Murray for election to our Board. If a vacancy is created on the Board as a result of the death, disability, retirement, resignation or removal of any Designee, EF Realisation has the right to nominate a replacement director.

On June 15, 2017, we entered into an Amended and Restated Securities Purchase Agreement (the “SPA”) with Chambers pursuant to which we sold to Chambers shares of two newly-created classes of preferred stock referred to collectively as the “Series A Preferred Stock.” On the same day, the we closed the transactions contemplated by the SPA (the “SPA Closing”). Pursuant to the terms of the SPA, (a) for so long as Chambers and other persons or entities who become holders of the securities issued or issuable under the SPA and who have previously been approved by the Company in its sole discretion (together with Chambers, the “Approved Holders”) beneficially own (i) at least 20% of the total number of outstanding shares of the Company’s Class A Common Stock, on anas-converted basis, or (ii) at least 30% of the number of shares of Series A Preferred Stock issued to Chambers at the SPA Closing and at least 15% of the total number of outstanding shares of the Company’s Class A Common Stock, on anas-converted basis, the Approved Holders will have the right to designate two directors to the Board; and (b) for so long as the Approved Holders beneficially own (i) at least 10% of the total number of outstanding shares of the Company’s Class A Common Stock, on anas-converted basis, or (ii) at least 15% of the number of shares of Series A Preferred Stock issued to Chambers at the SPA Closing and at least 5% of the total number of outstanding shares of Class A Common Stock, on anas-converted basis, the Approved Holders will have the right to designate one director to the Board. Pursuant to the terms described above, Chambers currently has the right to designate two nominees and has designated Matthew B. Ockwood and Philip Z. Pace as director nominees for election to our Board. If a vacancy is created on the Board as a result of the death, disability, retirement, resignation or removal of any Chambers designee, the Approved Holders have the right to nominate a replacement director.

Any other vacancies or newly created directorships on the Board may be filled only by a majority vote of the remaining directors on the Board.

CORPORATE GOVERNANCE

DIRECTOR INDEPENDENCE

Henry B. Ellis, John H. Murray, Matthew B. Ockwood, Stephen H. Oglesby, Phillip Z. Pace, John H. Pinkerton and Randy L. Wolsey qualify as independent under the rules of the Nasdaq Stock Market LLC (the “Nasdaq Rules”). The independence definition under the Nasdaq Rules includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq Rules, our Board has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of our Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our Board reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as they may relate to us and our management. Specifically, the Board considered that Mr. Murray is aCo-Founder, Executive Chairman and Chief Compliance Officer of Ecofin Limited, affiliates of which owned 16.9% of the Company’s Class A Common Stock as of the Record Date. In addition, the Board considered that Mr. Ockwood is a Managing Director, and Mr. Pace is a Partner, of Chambers, which owned 100% of the Company’s SeriesA-1 Preferred Stock, and 36.7% of the Company’s Class A Common Stock, on anas-converted basis, as of the Record Date.

Our Audit and Risk Committee, our Compensation Committee and our Nominating and Corporate Governance Committee are each currently composed entirely of independent directors.

There are no family relationships among any of our directors or executive officers.

DIRECTOR CANDIDATES

The Nominating and Corporate Governance Committee is responsible for identifying and reviewing the qualifications of potential director candidates and recommending to the Board those candidates to be nominated for election to the Board, subject to any obligations and procedures governing the nomination of directors to the Board that may be included in the Board Representation Agreement, the SPA and any other stockholders agreement to which we may enter into.

To facilitate the search process for director candidates, the Nominating and Corporate Governance Committee may solicit our current directors and executives for the names of potentially qualified candidates or may ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates or consider director candidates recommended by our stockholders. Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from us and potential conflicts of interest and determines if candidates meet the qualifications desired by the committee of candidates for election as director. Matthew B. Ockwood, elected to the Board in November 2017, and Philip Z. Pace, elected to the Board in June 2017, are director nominees designated by Chambers under the SPA.

In accordance with our Corporate Governance Guidelines, in evaluating the suitability of individual candidates, the Nominating and Corporate Governance Committee will consider (i) minimum individual qualifications, including a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments and (ii) all other factors it considers appropriate, which may include experience in corporate management, experience as a board member of other public companies, relevant professional or academic experience, leadership skills, financial and accounting background, executive compensation background and whether the candidate has the time required to fully participate as a director of the Company. Our Corporate Governance Guidelines provide that the Board should monitor the mix of specific experience, qualifications and skills of its directors in order to assure that the Board, as a whole, has the necessary tools to perform its oversight function effectively in light of the Company’s business and structure.

28

CORPORATE GOVERNANCE

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, 111 Boland Street, Suite 300, Fort Worth, TX, 76107. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

COMMUNICATIONS FROM STOCKHOLDERS

The Board will give appropriate attention to written communications that are submitted by stockholders and will respond if and as appropriate. Our Secretary is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the directors as he considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Secretary and Chairman of the Board consider to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders who wish to send communications on any topic to the Board should address such communications to the Board in writing: c/o Secretary, Lonestar Resources US Inc., 111 Boland Street, Suite 300, Fort Worth, Texas, 76107.

BOARD LEADERSHIP STRUCTURE AND ROLE IN RISK OVERSIGHT

Our Board exercises its discretion in combining or separating the roles of Chairman of the Board and Chief Executive Officer as it deems appropriate in light of prevailing circumstances. Our Board is currently chaired by Mr. Pinkerton. Our Board believes that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of the Board as a whole. As such, Mr. Bracken serves as our Chief Executive Officer while Mr. Pinkerton serves as the Chairman of the Board.

Risk assessment and oversight are an integral part of our governance and management processes. Our management is responsible for ourday-to-day risk management activities. Our Board oversees the implementation of risk mitigation strategies by management and encourages management to promote a culture that incorporates risk management into our corporate strategy andday-to-day business operations. Management discusses strategic and operational risks, including cybersecurity risks, at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the Board at regular board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks. Our Board is apprised of particular risk management matters in connection with its general oversight and approval of corporate matters and significant transactions. Our Board administers this oversight function directly through the Board as a whole, as well as through various standing committees of the Board that address risks inherent in their respective areas of oversight. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership structure. With regard to cybersecurity, we seek to maintain the security of computers, computer networks and data storage resources, and regularly review and discuss best practices with regard to cybersecurity.

PERIODIC BOARD EVALUATION

Our Corporate Governance Guidelines require the Nominating and Corporate Governance Committee to oversee a periodic assessment of the Board and its committees.

CORPORATE GOVERNANCE

CODE OF ETHICS

We have a written Code of Business Conduct and Ethics (the “Code of Ethics”) that applies to our directors, officers and employees. We have posted a current copy of the Code of Ethics in the “Governance” section of the “Shareholder Information” page of our website, www.lonestarresources.com.

ATTENDANCE BY MEMBERS OF THE BOARD OF DIRECTORS AT MEETINGS

There were 6 meetings of the Board during the fiscal year ended December 31, 2017. During the fiscal year ended December 31, 2017, each director attended at least 75% of the aggregate of all meetings of the Board and meetings of the committees on which the director served during the period in which he served as a director.

Under our Corporate Governance Guidelines, which is available on our website at www.lonestarresources.com, a director is expected to spend the time and effort necessary to properly discharge his or her responsibilities. Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and all committees on which the director sits (including separate meetings of the independent directors), with the understanding that, on occasion, a director may be unable to attend a meeting. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify the Chairman of the Board or the Chairman of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of anin-person meeting.

We do not maintain a formal policy regarding director attendance at the Annual Meeting. Two directors attended the 2017 Annual Meeting of Stockholders. Absent compelling circumstances, all directors are expected to attend future annual meetings in person or telephonically.

Narrative Disclosure to the Summary Compensation Table

For 2016 and 2017, the principal elements of compensation provided to the named executive officers were base salaries, annual cash bonuses, restricted stock unit awards, stock appreciation rights, and retirement, health, welfare and additional benefits.

No Employment Agreements. Currently none of our executive officers are parties to any employment agreement or compensatory arrangement, other than customary indemnification agreements.

Base Salary. Base salaries are generally set at levels deemed necessary to attract and retain individuals with superior talent commensurate with their relative expertise and experience. No base salary increases were made in 2017.

Annual Cash Bonuses. Annual cash awards are used to motivate and reward our executives. Our executives are eligible to receive a discretionary annual cash bonus, which for 2017 will not be based on any specific performance metrics or criteria. Unless otherwise determined, awards have historically been subject to an individual’s continued employment through the date of payment of the award.

Restricted Stock Unit Awards. Restricted stock units represent a right to receive stock at the end of a specified vesting period. We use restricted stock units to motivate and retain our executives. On February 23, 2017, we granted awards of restricted stock units covering 150,000 shares to Mr. Bracken, 75,000 shares to Mr. Schneider, and 25,000 shares to Mr. Olle. The restricted stock units vest over a three-year period, with 40% vesting on the first anniversary of issuance, and 30% on each of the second and third anniversaries of issuance, such that the restricted stock units will be fully vested on the third anniversary of issuance. Restricted stock units will be paid in Class A Voting Common Stock or cash at our option after the vesting of the applicable restricted stock unit. We determine the fair value of granted restricted stock units based on the market price of our Class A Voting Common Stock on the date of grant. Compensation expense for granted restricted stock units is recognized over the vesting period.

Stock Appreciation Rights Awards. Stock appreciation rights allow the recipient to receive the appreciation in the fair market value of our common stock between the date of grant and the exercise date. On February 23, 2017, we granted awards of stock appreciation rights covering 150,000 shares to Mr. Bracken, 75,000 shares to Mr. Schneider, and 25,000 shares to Mr. Olle. The awards of stock appreciation rights vest over a three-year period, with 40% vesting on the first anniversary of issuance, and 30% on each of the second and third anniversaries of issuance, such that the stock appreciation rights will be fully vested on the third anniversary of issuance. The stock appreciation rights will expire five-years after the date of issuance. Stock appreciation rights will be paid in cash or common stock at holder’s election once the stock appreciation rights have vested, with the provision that the Company possesses sufficient liquidity to allow for cash settlement of the stock appreciation rights.

All Other Compensation. In addition to the compensation discussed above, certain executives receive health and welfare plan benefits and an automobile allowance. The Company provides a 401(k) plan to all eligible full-time employees which allows forpre-tax employee contributions up to the maximum allowed by the Internal Revenue

34

EXECUTIVE AND DIRECTOR COMPENSATION

Code of 1986, as amended (the “Code”). The Company supplements the employee’s contribution by providing a matching contribution of 100% of up to the first 4% contributed by each employee. This matching contribution is deposited on each semi-monthly payroll and is 100% vested to the employee’s account.

Lonestar Resources US Inc. Amended and Restated 2016 Incentive Award Plan.In 2016, we adopted the A&R 2016 Plan for our employees, consultants and directors and affiliates who perform services for us. The Long-Term Incentive Plan was amended and restated on May 24, 2017. The purpose of the A&R 2016 Plan is to provide a means to attract and retain individuals to serve as directors, employees and consultants who provide services to us by affording such individuals a means to acquire and maintain ownership of awards, the value of which is tied to the performance of our Class A Voting Common Stock. The A&R 2016 Plan provides for grants of cash payments, stock options, stock appreciation rights, restricted stock or units, bonus stock, dividend equivalents, and other stock-based awards with the total number of shares of stock available for issuance under the Incentive Plan not to exceed 2,200,000 shares. In a proposal to this proxy statement, we are asking our stockholders to approve an amendment to the A&R 2016 Plan to increase the number of shares of our Class A Common Stock available for issuance thereunder by 800,000 shares, so that a total of 3,000,000 shares of our Class A Common Stock would be authorized for issuance under the A&R 2016 Plan. Prior to 2016, long-term incentive awards had historically been granted in the form of stock options under our A&R 2016 Plan. However, as of December 31, 2017, all stock options had expired in accordance with their terms, without any such options having been exercised. As of December 31, 2017, the total amount of unrecognized compensation cost related to nonvested restricted stock awards, to be recognized as expense subsequent to December 31, 2017, was approximately $2.7 million, and the related weighted average period over which it is expected to be recognized is approximately 2.2 years.

The number of shares beneficially owned by each stockholder is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which a person has sole or shared voting power or investment power. Applicable percentage ownership is based on 24,634,313 shares of Class A Common Stock and 85,857 shares of SeriesA-1 Preferred Stock outstanding as of March 29, 2018. Except as described in the footnotes to the table below, in computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares subject to stock appreciation rights, options, warrants, restricted stock units or other rights or conversion privileges held by such person, that may be exercisable or settled for or converted into shares of Class A Common Stock within 60 days of March 29, 2018 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each beneficial owner listed below is c/o Lonestar Resources US Inc., 111 Boland Street, Suite 300, Fort Worth, Texas, 76107.

Certain Relationships

POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

Our Board has adopted a written Related Person Transaction Policy and Procedures, setting forth the policies and procedures for the review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of RegulationS-K, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we (including any of our subsidiaries) are, were or will be a participant, where the amount involved exceeds $120,000 in any fiscal year and a related person has, had or will have a direct or indirect material interest, which may include, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person.

Under the policy, management is responsible for implementing procedures to obtain information with respect to potential related person transactions, and then determining whether such transactions constitute related person transactions subject to the policy. Management then is required to present to the Audit and Risk Committee each proposed related person transaction. In reviewing and approving any such transactions, our Audit and Risk Committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction. If advance Audit and Risk Committee approval of a related person transaction is not feasible, then the transaction may be preliminarily entered into by management upon prior approval by the Chairperson of the Audit and Risk Committee, subject to ratification of the transaction by the Audit and Risk Committee at the Audit and Risk Committee’s next scheduled meeting. Any related person transaction must be approved or ratified by the Audit and Risk Committee in order to be consummated or continue, as applicable. Management is responsible for updating the Audit and Risk Committee as to any material changes to any approved or ratified related person transaction and for providing a status report at least annually of all current related person transactions at a regularly scheduled meeting of the Audit and Risk Committee. No director may participate in approval of a related person transaction for which he or she is a related person. All of the transactions, agreements or relationships described in this section occurred prior to the adoption of this policy.

The following are certain transactions, arrangements and relationships with our directors, executive officers and stockholders owning 5% or more of our outstanding Class A Common Stock or SeriesA-1 Preferred Stock.

CHAMBERS

On June 15, 2017, we entered into the SPA with Chambers and simultaneously closed the transactions contemplated thereby. Pursuant to the SPA, we sold to Chambers, in a private placement under the Securities Act of 1933, shares of the our newly-created SeriesA-1 Preferred Stock as well as shares of our SeriesA-2 Convertible Participating Preferred Stock, par value $0.001 per share (together with the SeriesA-1 Preferred Stock, the “Series A Preferred Stock”) which was converted into SeriesA-1 Preferred Stock on November 3, 2017. The aggregate purchase price under the SPA was $78 million.

Pursuant to the terms of the SPA, (a) for so long as Chambers and other persons or entities who become holders of the securities issued or issuable under the SPA and who have previously been approved by the Company in its sole discretion (together with Chambers, the “Approved Holders”) beneficially own (i) at least 20% of the total number of outstanding shares of the Company’s Class A Common Stock, on anas-converted basis, or (ii) at least 30% of the number of shares of Series A Preferred Stock issued to Chambers at the SPA Closing and at least 15% of the total number of outstanding shares of the Company’s Class A Common Stock, on anas-converted basis, the Approved Holders will have the right to designate two directors to the Board; and (b) for so long as the Approved Holders beneficially own (i) at least 10% of the total number of outstanding shares of the Company’s Class A Common Stock, on anas-converted basis, or (ii) at least 15% of the number of shares of Series A Preferred Stock issued to Chambers at the SPA Closing and at least 5% of the total number of outstanding shares

CERTAIN RELATIONSHIPS

of the Company’s Class A Common Stock, on anas-converted basis, the Approved Holders will have the right to designate one director to the Board. Pursuant to the terms described above, Chambers currently has the right to designate two nominees and have designated Matthew B. Ockwood and Philip Z. Pace for election to our Board. If a vacancy is created on the Board as a result of the death, disability, retirement, resignation or removal of any Designee, the Approved Holders have the right to nominate a replacement director.

For so long as the Approved Holders beneficially own at least 10% of the total number of outstanding shares of the Company’s Class A Common Stock, on anas-converted basis, or at least 15% of the number of Series A Preferred Stock issued to Chambers at the SPA Closing, the Company cannot undertake certain actions without the prior consent of holders of a majority of all shares of the Company’s Class A Common Stock, on anas-converted basis, held by the Approved Holders.

In connection with the SPA Closing and the issuance of shares of Series A Preferred Stock, the Company entered into a registration rights agreement with Chambers (the “Chambers RRA”). Under the Chambers RRA, the Company has agreed to provide to Chambers certain customary demand and piggyback registration rights relating to Chambers’ ownership of Company stock. The Chambers RRA contains customary terms and conditions, including certain customary indemnification obligations.

LEUCADIA

On August 2, 2016, the Company entered into a securities purchase agreement, registration rights agreement and an equity commitment agreement with Juneau Energy, LLC (“Juneau”) and Leucadia National Corporation (“Leucadia”). Pursuant to the registration rights agreement, the Company has agreed to register for resale certain Class A Common Stock issued or issuable to Juneau and Leucadia, including shares of Class A Common Stock issuable upon exercise of warrants. Leucadia agreed, pursuant to the equity commitment agreement, to purchase a certain number of Class A Common Stock in case the Company elected to pursue an equity offering prior to December 31, 2016. Pursuant to the equity commitment agreement, Leucadia purchased 3,478,261 shares of Class A Common Stock (costing $20 million) through our equity offering that closed on December 22, 2016. In connection with Leucadia’s equity commitment, the Company paid Leucadia on January 3, 2017 a $1 million fee. In the event Leucadia purchased not less than its commitment amount, the Company agreed to use commercially reasonable efforts to enter into arrangements to provide Leucadia with the right to appoint one director to the Board of the Company, provided that such right will terminate at such time as Leucadia and its affiliates own a number of shares of Class A Common Stock equal to less than 50% of the shares purchased by Leucadia and its affiliates in such offering. Leucadia has elected to take an observer position on the board of directors, with no voting rights.

EF REALISATION

On October 26, 2016, we entered into a Board Representation Agreement with EF Realisation. Under the Board Representation Agreement, for as long as EF Realisation owns 15% or more of the issued and outstanding shares of our Class A Common Stock, it has the right to nominate up to, but no more than, two directors to serve on the Board and for as long as EF Realisation owns at least 10% but less than 15% of our issued and outstanding shares of Class A Common Stock, it has the right to nominate up to, but no more than, one director to serve on the Board.

On October 26, 2016, we entered into a Registration Rights Agreement (the “EF Realisation RRA”) with EF Realisation, pursuant to which we agreed to register for resale Class A Common Stock held by EF Realisation.

SANCHEZ ENERGY

On May 26, 2017, the Company entered into a purchase and sale agreement (the “Original Marquis PSA” and, as amended by the Amendment to Marquis PSA (as defined below), the “Marquis PSA”) with SN Marquis LLC (“Marquis”), a subsidiary of Sanchez Energy Corporation, pursuant to which the Company agreed to acquire certain oil and gas assets in Fayetts, Gonzales and Lavaca Counties, Texas (the “Marquis Assets”) from Marquis. On June 15, 2017, the Company entered into Amendment No. 1 to the Original Marquis PSA (the “Amendment to Marquis PSA”), in order to amend the consideration paid to Marquis and issue shares of Series B Preferred Stock to Marquis instead of shares of Class A Common Stock. On June 15, 2017, the Company completed the transactions contemplated by the Marquis PSA (the “Marquis Closing”) for total consideration of approximately $50 million (net of approximately $6 million in customary purchase price adjustments), consisting of approximately $44 million in cash and 1,500,000 shares of the Company’s Series B Preferred Stock, which was converted into shares of the Company’s Class A Common Stock on aone-to-one basis on November 3, 2017.

In connection with the Marquis Closing, the Company entered into a registration rights agreement with Marquis (the “Marquis RRA”). Pursuant to the Marquis RRA, the Company has agreed to provide to Marquis certain customary demand and piggyback registration rights relating to Marquis’s ownership of Company stock. The Marquis RRA contains customary terms and conditions, including certain customary indemnification obligations.

RESALE REGISTRATION STATEMENT

In accordance with our obligations under our registration rights agreements described above, we filed a registration statement on FormS-3 (FileNo. 333-221392) (the “FormS-3”) that was declared effective by the SEC in February 2018. The FormS-3 registered the resale of the shares of Class A Common Stock (or securities exercisable for or convertible into Class A Common Stock) held by Chambers, EF Realisation, Leucadia and Sanchez Energy.

DANIEL R. LOCKWOOD

New Tech Global Ventures, LLC, a company in which our current director Daniel R. Lockwood owns a minority limited partnership interest, has provided field engineering staff and consultancy services for the Company since 2013. The total cost for such services was approximately $1,015,000 in 2017.

INDEMNIFICATION AGREEMENTS

We have entered into indemnification agreements with each of our directors and executive officers. These agreements, among other things, require us or will require us to indemnify each director and executive officer to the fullest extent permitted by Delaware law, including indemnification of expenses such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of us, arising out of the person’s services as a director or executive officer.

Interest of Certain Persons in Matters to Be Acted Upon

No person who has served as an officer or director of the Company since the beginning of our last fiscal year, and no associate of such a person, has any substantial interest in the matters to be acted upon at the Annual Meeting, other than (i) an interest in awards that may be granted to our officers and directors under the A&R 2016 Plan, as described with respect to Proposal 3 above, (ii) as a result of his or her role as an officer or director of the Company, or (iii) in his role as a shareholder in proportion to his percentage shareholding.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and stockholders who beneficially own more than 10% of any class of our equity securities registered pursuant to Section 12 of the Exchange Act (collectively, the “Reporting Persons”) to file initial statements of beneficial ownership of securities and statements of changes in beneficial ownership of securities with respect to our equity securities with the SEC. All Reporting Persons are required by SEC regulation to furnish us with copies of all reports that such Reporting Persons file with the SEC pursuant to Section 16(a). Based solely on our review of the copies of such forms received by us and upon written representations of the Reporting Persons received by us, we believe that there has been compliance with all Section 16(a) filing requirements applicable to such Reporting Persons with respect to the year ended December 31, 2017, except that the following forms were filed late: one Form 4 reporting one transaction for Bernard Lambilliotte (who at the time was serving as a director of the Company), one Form 4 reporting nine transactions (four of which occurred during the 2016 fiscal year) for Henry Ellis and one Form 4 reporting three transactions for Randy Wolsey.

SEC rules permit management to vote proxies in its discretion in certain cases if the stockholder does not comply with this deadline and, in certain other cases notwithstanding the stockholder’s compliance with this deadline.

We reserve the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.

2016 INCENTIVE PLAN

ARTICLE I.

PURPOSE

This Plan is a restatement of the Lonestar Resources US Inc. 2016 Incentive Plan, which was adopted by the Board on March 22, 2016 as a successor to the Lonestar Resources Limited 2012 Employee Share Option Plan for use following there-domiciliation of Lonestar Resources Limited to the United States by means of the Company’s acquisition of Lonestar Resources Limited. The Plan was further amended and restated on May 24, 2017 by a majority in interest of the Company’s stockholders. The Plan’s purpose is to enhance the Company’s ability to attract, retain and motivate persons who make (or are expected to make) important contributions to the Company by providing these individuals with equity ownership and other incentive opportunities. Capitalized terms used in the Plan are defined in Article XI.

ARTICLE II.

ELIGIBILITY

Service Providers are eligible to be granted Awards under the Plan, subject to the limitations described herein.

ARTICLE III.

ADMINISTRATION AND DELEGATION

3.1Administration. The Plan is administered by the Administrator. The Administrator has authority to determine which Service Providers receive Awards, grant Awards and set Award terms and conditions, subject to the conditions and limitations in the Plan. The Administrator also has the authority to take all actions and make all determinations under the Plan, to interpret the Plan and Award Agreements and to adopt, amend and repeal Plan administrative rules, guidelines and practices as it deems advisable. The Administrator may correct defects and ambiguities, supply omissions and reconcile inconsistencies in the Plan or any Award as it deems necessary or appropriate to administer the Plan and any Awards. The Administrator’s determinations under the Plan are in its sole discretion and will be final and binding on all persons having or claiming any interest in the Plan or any Award.

3.2Appointment of Committees. To the extent Applicable Laws permit, the Board may delegate any or all of its powers under the Plan to one or more Committees or officers of the Company or any of its Subsidiaries. The Board may abolish any Committee orre-vest in itself any previously delegated authority at any time.

ARTICLE IV.

STOCK AVAILABLE FOR AWARDS

4.1Number of Shares. Subject to adjustment under Article VIII and the terms of this Article IV, Awards may be made under the Plan covering up to the Overall Share Limit. Shares issued under the Plan may consist of authorized but unissued Shares, Shares purchased on the open market or treasury Shares.

4.2Share Recycling. If all or any part of an Award (including for the avoidance of doubt an Award granted prior to the Restatement) expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, canceled without having been fully exercised or forfeited, in any case, in a manner that results in the Company acquiring Shares covered by the Award at a price not greater than the price (as adjusted to reflect any Equity Restructuring)

A-1

paid by the Participant for such Shares or not issuing any Shares covered by the Award, the unused Shares covered by the Award will, as applicable, become or again be available for Award grants under the Plan. Further, Shares delivered (either by actual delivery or attestation) to the Company by a Participant to satisfy the applicable exercise or purchase price of an Award and/or to satisfy any applicable tax withholding obligation (including Shares retained by the Company from the Award being exercised or purchased and/or creating the tax obligation) will, as applicable, become or again be available for Award grants under the Plan. The payment of Dividend Equivalents in cash in conjunction with any outstanding Awards shall not count against the Overall Share Limit.

4.3Incentive Stock Option Limitations. Notwithstanding anything to the contrary herein, no more than 3,000,000 Shares may be issued pursuant to the exercise of Incentive Stock Options.

4.4Substitute Awards. In connection with an entity’s merger or consolidation with the Company or the Company’s acquisition of an entity’s property or stock, the Administrator may grant Awards in substitution for any options or other stock or stock-based awards granted before such merger or consolidation by such entity or its affiliate. Substitute Awards may be granted on such terms as the Administrator deems appropriate, notwithstanding limitations on Awards in the Plan. Substitute Awards will not count against the Overall Share Limit (nor shall Shares subject to a Substitute Award be added to the Shares available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute Incentive Stock Options will count against the maximum number of Shares that may be issued pursuant to the exercise of Incentive Stock Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under apre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of suchpre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not be added to the Shares available for Awards under the Plan as provided above); provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of thepre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees or Directors prior to such acquisition or combination.

4.5Non-Employee Director Compensation. Notwithstanding any provision to the contrary in the Plan, the Administrator may establish compensation fornon-employee Directors from time to time, subject to the limitations in the Plan. The Administrator will from time to time determine the terms, conditions and amounts of all suchnon-employee Director compensation in its discretion and pursuant to the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, provided that the sum of any cash compensation, or other compensation, and the value (determined as of the grant date in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto) of Awards granted to anon-employee Director as compensation for services as anon-employee Director during any fiscal year of the Company may not exceed $500,000 increased to $1,000,000 in the fiscal year of his or her initial service as anon-employee Director. The Administrator may make exceptions to this limit for individualnon-employee Directors in extraordinary circumstances, as the Administrator may determine in its discretion, provided that thenon-employee Director receiving such additional compensation may not participate in the decision to award such compensation or in other contemporaneous compensation decisions involvingnon-employee Directors.

ARTICLE V.

STOCK OPTIONS AND STOCK APPRECIATION RIGHTS

5.1General. The Administrator may grant Options or Stock Appreciation Rights to Service Providers subject to the limitations in the Plan, including any limitations in the Plan that apply to Incentive Stock Options.

A-2

The Administrator will determine the number of Shares covered by each Option and Stock Appreciation Right, the exercise price of each Option and Stock Appreciation Right and the conditions and limitations applicable to the exercise of each Option and Stock Appreciation Right. A Stock Appreciation Right will entitle the Participant (or other person entitled to exercise the Stock Appreciation Right) to receive from the Company upon exercise of the exercisable portion of the Stock Appreciation Right an amount determined by multiplying the excess, if any, of the Fair Market Value of one Share on the date of exercise over the exercise price per Share of the Stock Appreciation Right by the number of Shares with respect to which the Stock Appreciation Right is exercised, subject to any limitations of the Plan or that the Administrator may impose and payable in cash, Shares valued at Fair Market Value or a combination of the two as the Administrator may determine or provide in the Award Agreement.

5.2Exercise Price. The Administrator will establish each Option’s and Stock Appreciation Right’s exercise price and specify the exercise price in the Award Agreement. The exercise price will not be less than 100% of the Fair Market Value on the grant date of the Option or Stock Appreciation Right. Notwithstanding the foregoing, if on the last day of the term of an Option or Stock Appreciation Right the Fair Market Value of one Share exceeds the applicable exercise or base price per Share, the Participant has not exercised the Option or Stock Appreciation Right and remains employed by the Company or one of its Subsidiaries and the Option or Stock Appreciation Right has not expired, the Option or Stock Appreciation Right shall be deemed to have been exercised by the Participant on such day with payment made by withholding Shares otherwise issuable in connection with its exercise. In such event, the Company shall deliver to the Participant the number of Shares for which the Option or Stock Appreciation Right was deemed exercised, less the number of Shares required to be withheld for the payment of the total purchase price and required withholding taxes; provided, however, any fractional Share shall be settled in cash.

5.3Duration. Each Option or Stock Appreciation Right will be exercisable at such times and as specified in the Award Agreement, provided that the term of an Option or Stock Appreciation Right will not exceed ten years. Notwithstanding the foregoing and unless determined otherwise by the Company, in the event that on the last business day of the term of an Option or Stock Appreciation Right (other than an Incentive Stock Option) (i) the exercise of the Option or Stock Appreciation Right is prohibited by Applicable Law, as determined by the Company, or (ii) Shares may not be purchased or sold by the applicable current or former Service Provider due to any Company insider trading policy (including blackout periods) or a“lock-up” agreement undertaken in connection with an issuance of securities by the Company, the term of the Option or Stock Appreciation Right shall be extended for a period of thirty (30) days following the end of the legal prohibition,black-out period orlock-up agreement, as determined by the Company; provided, however, in no event shall the extension last beyond the ten year term of the applicable Option or Stock Appreciation Right unless the exercise would violate an Applicable Law. Notwithstanding the foregoing, if the Participant, prior to the end of the term of an Option or Stock Appreciation Right, violates thenon-competition,non-solicitation or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company or any of its Subsidiaries, the right to exercise the Option or Stock Appreciation Right, as applicable, may be terminated by the Company and the Company may suspend the Participant’s right to exercise the Option or Stock Appreciation Right when it reasonably believes that the Participant has participated in any such violation. In addition, if, prior to the end of the term of an Option or Stock Appreciation Right, the Participant is given notice by the Company or any of its Subsidiaries of the termination of his or her employment or other relationship by the Company or any of its Subsidiaries for Cause, and the effective date of such employment or other termination is subsequent to the date of the delivery of such notice, the right to exercise the Option or Stock Appreciation Right, as applicable, shall be suspended from the time of the delivery of such notice until the earlier of (i) such time as it is determined or otherwise agreed that the Participant’s employment or other relationship shall not be terminated for Cause as provided in such notice or (ii) the effective date of such termination of employment or other relationship (in which case the right to exercise the Option or Stock Appreciation Right, as applicable, shall terminate immediately upon the effective date of such termination of employment or other relationship).

A-3

5.4Exercise. Options and Stock Appreciation Rights may be exercised by delivering to the Company a written notice of exercise, in a form the Administrator approves (which may be electronic), signed by the person authorized to exercise the Option or Stock Appreciation Right, together with, as applicable, payment in full (i) as specified in Section 5.5 for the number of Shares for which the Award is exercised and (ii) as specified in Section 9.5 for any applicable taxes. Unless the Administrator otherwise determines, an Option or Stock Appreciation Right may not be exercised for a fraction of a Share.

5.5Payment Upon Exercise. Subject to Section 10.8, any Company insider trading policy (including blackout periods) and Applicable Laws, the exercise price of an Option must be paid by:

(a) cash, wire transfer of immediately available funds or by check payable to the order of the Company; provided, that, the Company may limit the use of one of the foregoing exercise methods if one or more of the exercise methods below is permitted;

(b) if there is a public market for Shares at the time of exercise, unless the Company otherwise determines, (A) delivery (including telephonically to the extent permitted by the Company) of a notice that the Participant has placed a market sell order with a broker acceptable to the Company with respect to Shares then issuable upon exercise of the Option and that the broker has been directed to deliver promptly to the Company sufficient funds to pay the exercise price, or (B) the Participant’s delivery to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to pay the exercise price; provided that such amount is paid to the Company at such time as may be required by the Administrator;

(c) to the extent permitted by the Administrator, delivery (either by actual delivery or attestation) of Shares owned by the Participant valued at their Fair Market Value;

(d) to the extent permitted by the Administrator, surrendering Shares then issuable upon the Option’s exercise valued at their Fair Market Value on the exercise date;

(e) to the extent permitted by the Administrator, delivery of a promissory note or any other property that the Administrator determines is good and valuable consideration; or

(f) to the extent permitted by the Company, any combination of the above payment forms approved by the Administrator.

ARTICLE VI.

RESTRICTED STOCK; RESTRICTED STOCK UNITS

6.1General. The Administrator may grant Restricted Stock, or the right to purchase Restricted Stock, to any Service Provider, subject to forfeiture or the Company’s right to repurchase all or part of such shares at their issue price or other stated or formula price from the Participant if conditions the Administrator specifies in the Award Agreement are not satisfied before the end of the applicable restriction period or periods that the Administrator establishes for such Award. In addition, the Administrator may grant to Service Providers Restricted Stock Units, which may be subject to vesting and forfeiture conditions during the applicable restriction period or periods, as set forth in an Award Agreement. The Administrator will determine and set forth in the Award Agreement the terms and conditions for each Restricted Stock and Restricted Stock Unit Award, subject to the conditions and limitations contained in the Plan.

6.2Restricted Stock.

(a)Dividends. Participants holding shares of Restricted Stock will be entitled to all ordinary cash dividends paid with respect to such Shares, unless the Administrator provides otherwise in the Award

A-4

Agreement. In addition, unless the Administrator provides otherwise, if any dividends or distributions are paid in Shares, or consist of a dividend or distribution to holders of Common Stock of property other than an ordinary cash dividend, the Shares or other property will be subject to the same restrictions on transferability and forfeitability as the shares of Restricted Stock with respect to which they were paid.

(b)Stock Certificates. The Company may require that the Participant deposit in escrow with the Company (or its designee) any stock certificates issued in respect of shares of Restricted Stock, together with a stock power endorsed in blank.

6.3Restricted Stock Units.

(a)Settlement. The Administrator may provide that settlement of Restricted Stock Units will occur upon or as soon as reasonably practicable after the Restricted Stock Units vest or will instead be deferred, on a mandatory basis or at the Participant’s election, in a manner intended to comply with Section 409A.

(b)Stockholder Rights. A Participant will have no rights of a stockholder with respect to Shares subject to any Restricted Stock Unit unless and until the Shares are delivered in settlement of the Restricted Stock Unit.

(c)Dividend Equivalents. If the Administrator provides, a grant of Restricted Stock Units may provide a Participant with the right to receive Dividend Equivalents. Dividend Equivalents may be paid currently or credited to an account for the Participant, settled in cash or Shares and subject to the same restrictions on transferability and forfeitability as the Restricted Stock Units with respect to which the Dividend Equivalents are granted and subject to other terms and conditions as set forth in the Award Agreement.

ARTICLE VII.

OTHER STOCK OR CASH BASED AWARDS

Other Stock or Cash Based Awards may be granted to Participants, including Awards entitling Participants to receive Shares to be delivered in the future and including annual or other periodic or long-term cash bonus awards (whether based on specified Performance Criteria or otherwise), in each case subject to any conditions and limitations in the Plan. Such Other Stock or Cash Based Awards will also be available as a payment form in the settlement of other Awards, as standalone payments and as payment in lieu of compensation to which a Participant is otherwise entitled. Other Stock or Cash Based Awards may be paid in Shares, cash or other property, as the Administrator determines. Subject to the provisions of the Plan, the Administrator will determine the terms and conditions of each Other Stock or Cash Based Award, including any purchase price, performance goal (which may be based on the Performance Criteria), transfer restrictions, and vesting conditions, which will be set forth in the applicable Award Agreement.

ARTICLE VIII.

ADJUSTMENTS FOR CHANGES IN COMMON STOCK

AND CERTAIN OTHER EVENTS

8.1Equity Restructuring. In connection with any Equity Restructuring, notwithstanding anything to the contrary in this Article VIII, the Administrator will equitably adjust each outstanding Award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of securities subject to each outstanding Award and/or the Award’s exercise price or grant price (if applicable), granting new Awards to Participants, and making a cash payment to Participants. The adjustments provided under this Section 8.1 will be nondiscretionary and final and binding on the affected Participant and the Company; provided that the Administrator will determine whether an adjustment is equitable.

(a) To provide for the cancellation of any such Award in exchange for either an amount of cash or other property with a value equal to the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights under the vested portion of such Award, as applicable; provided that, if the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights, in any case, is equal to or less than zero, then the Award may be terminated without payment;

(b) To provide that such Award shall vest and, to the extent applicable, be exercisable as to all shares covered thereby, notwithstanding anything to the contrary in the Plan or the provisions of such Award;

(c) To provide that such Award be assumed by the successor or survivor corporation or entity, or a parent or subsidiary thereof, or shall be substituted for by awards covering the stock of the successor or survivor corporation or entity, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and/or applicable exercise or purchase price, in all cases, as determined by the Administrator;

(d) To make adjustments in the number and type of shares of Common Stock (or other securities or property) subject to outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of the limitations in Article IV hereof on the maximum number and kind of shares which may be issued) and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards;

(e) To replace such Award with other rights or property selected by the Administrator; and/or

(f) To provide that the Award will terminate and cannot vest, be exercised or become payable after the applicable event.

8.3Acceleration Upon a Change in Control. Notwithstanding anything in Section 8.2 to the contrary, and except as may otherwise be provided in any applicable Award Agreement or other written agreement between the Company or any of its Subsidiaries and a Participant, if a Change in Control occurs and Awards are not continued, converted, assumed, or replaced by (i) the Company or a Subsidiary or (ii) a Successor Entity, then immediately prior to the Change in Control such Awards shall become fully exercisable and/or payable, as applicable, and all forfeiture, repurchase and other restrictions on such Awards shall lapse. Upon, or in anticipation of, a Change in Control, the Administrator may cause any and all Awards outstanding hereunder to terminate at a specific time in the future, including but not limited to the date of such Change in Control, and shall give each Participant the right to exercise such Awards during a period of time as the Administrator, in its sole and absolute discretion, shall determine.

8.4Administrative Stand Still. In the event of any pending stock dividend, stock split, combination or exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company

A-6

assets to stockholders, or any other extraordinary transaction or change affecting the Shares or the share price of Common Stock, including any Equity Restructuring or any securities offering or other similar transaction, for administrative convenience, the Administrator may refuse to permit the exercise of any Award for up to sixty days before or after such transaction.

8.5General. Except as expressly provided in the Plan or the Administrator’s action under the Plan, no Participant will have any rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number of Shares of any class or dissolution, liquidation, merger, or consolidation of the Company or other corporation. Except as expressly provided with respect to an Equity Restructuring under Section 8.1 above or the Administrator’s action under the Plan, no issuance by the Company of Shares of any class, or securities convertible into Shares of any class, will affect, and no adjustment will be made regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the Plan, any Award Agreements and the Awards granted hereunder will not affect or restrict in any way the Company’s right or power to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, (ii) any merger, consolidation dissolution or liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including securities with rights superior to those of the Shares or securities convertible into or exchangeable for Shares. The Administrator may treat Participants and Awards (or portions thereof) differently under this Article VIII.

ARTICLE IX.

GENERAL PROVISIONS APPLICABLE TO AWARDS

9.1Transferability. Except as the Administrator may determine or provide in an Award Agreement or otherwise for Awards other than Incentive Stock Options, Awards may not be sold, assigned, transferred, pledged or otherwise encumbered, either voluntarily or by operation of law, except by will or the laws of descent and distribution, or, subject to the Administrator’s consent, pursuant to a domestic relations order, and, during the life of the Participant, will be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, will include references to a Participant’s authorized transferee that the Administrator specifically approves.

9.2Documentation. Each Award will be evidenced in an Award Agreement, which may be written or electronic, as the Administrator determines. Each Award may contain terms and conditions in addition to those set forth in the Plan.

9.3Discretion. Except as the Plan otherwise provides, each Award may be made alone or in addition or in relation to any other Award. The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or Awards (or portions thereof) uniformly.

9.4Termination of Status. The Administrator will determine how the disability, death, retirement, authorized leave of absence or any other change or purported change in a Participant’s Service Provider status affects an Award and the extent to which, and the period during which, the Participant, the Participant’s legal representative, conservator, guardian or Designated Beneficiary may exercise rights under the Award, if applicable.

9.5Withholding. Each Participant must pay the Company, or make provision satisfactory to the Administrator for payment of, any taxes required by law to be withheld in connection with such Participant’s Awards by the date of the event creating the tax liability. The Company may deduct an amount sufficient to satisfy such tax obligations based on the minimum statutory withholding rates (or such other rate as may be determined by the Company after considering any accounting consequences or costs) from any payment of any kind otherwise due to a Participant. Subject to Section 10.8 and any Company insider trading policy (including blackout periods), Participants may satisfy such tax obligations (i) in cash, by wire transfer of immediately available funds, by check made payable to the order of the Company; provided, that, the Company may limit the

A-7

use of one of the foregoing methods if one or more of the exercise methods below is permitted, (ii) to the extent permitted by the Administrator, in whole or in part by delivery of Shares, including Shares retained from the Award creating the tax obligation, valued at their Fair Market Value, (iii) if there is a public market for Shares at the time the tax obligations are satisfied, unless the Company otherwise determines, (A) delivery (including telephonically to the extent permitted by the Company) of a notice that the Participant has placed a market sell order with a broker acceptable to the Company with respect to Shares then issuable upon exercise of the Award and that the broker has been directed to deliver promptly to the Company sufficient funds to satisfy the tax obligations, or (B) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to satisfy the tax withholding; provided that such amount is paid to the Company at such time as may be required by the Administrator, or (iv) to the extent permitted by the Company, any combination of the foregoing payment forms approved by the Administrator. If any tax withholding obligation will be satisfied under clause (ii) of the immediately preceding sentence by the Company’s retention of Shares from the Award creating the tax obligation and there is a public market for Shares at the time the tax obligation is satisfied, the Company may elect to instruct any brokerage firm determined acceptable to the Company for such purpose to sell on the applicable Participant’s behalf some or all of the Shares retained and to remit the proceeds of the sale to the Company or its designee, and each Participant’s acceptance of an Award under the Plan will constitute the Participant’s authorization to the Company and instruction and authorization to such brokerage firm to complete the transactions described in this sentence.

9.6Amendment of Award; Prohibition on Repricing. The Administrator may amend, modify or terminate any outstanding Award, including by substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive Stock Option to aNon-Qualified Stock Option. The Participant’s consent to such action will be required unless (i) the action, taking into account any related action, does not materially and adversely affect the Participant’s rights under the Award, or (ii) the change is permitted under Article VIII or pursuant to Section 10.6. Other than pursuant to Sections 8.1 and 8.2, the Administrator shall not without the approval of the Company’s stockholders (a) lower the exercise price per Share of an Option or Stock Appreciation Right after it is granted, (b) cancel an Option or Stock Appreciation Right when the exercise price per Share exceeds the Fair Market Value of one Share in exchange for cash or another Award, or (c) take any other action with respect to an Option or Stock Appreciation Right that the Company determines would be treated as a repricing under the rules and regulations of the principal U.S. national securities exchange on which the Shares are listed.

9.7Conditions on Delivery of Stock. The Company will not be obligated to deliver any Shares under the Plan or remove restrictions from Shares previously delivered under the Plan until (i) all Award conditions have been met or removed to the Company’s satisfaction, (ii) as determined by the Company, all other legal matters regarding the issuance and delivery of such Shares have been satisfied, including any applicable securities laws and stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the Administrator deems necessary or appropriate to satisfy any Applicable Laws. The Company’s inability to obtain authority from any regulatory body having jurisdiction, which the Administrator determines is necessary to the lawful issuance and sale of any securities, will relieve the Company of any liability for failing to issue or sell such Shares as to which such requisite authority has not been obtained.

9.8Acceleration. The Administrator may at any time provide that any Award will become immediately vested and fully or partially exercisable, free of some or all restrictions or conditions, or otherwise fully or partially realizable.

9.9Additional Terms of Incentive Stock Options. The Administrator may grant Incentive Stock Options only to employees of the Company, any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of the Code, respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code. If an Incentive Stock Option is granted to a Greater Than 10%

A-8

Stockholder, the exercise price will not be less than 110% of the Fair Market Value on the Option’s grant date, and the term of the Option will not exceed five years. All Incentive Stock Options will be subject to and construed consistently with Section 422 of the Code. By accepting an Incentive Stock Option, the Participant agrees to give prompt notice to the Company of dispositions or other transfers (other than in connection with a Change in Control) of Shares acquired under the Option made within (i) two years from the grant date of the Option or (ii) one year after the transfer of such Shares to the Participant, specifying the date of the disposition or other transfer and the amount the Participant realized, in cash, other property, assumption of indebtedness or other consideration, in such disposition or other transfer. Neither the Company nor the Administrator will be liable to a Participant, or any other party, if an Incentive Stock Option fails or ceases to qualify as an “incentive stock option” under Section 422 of the Code. Any Incentive Stock Option or portion thereof that fails to qualify as an “incentive stock option” under Section 422 of the Code for any reason, including becoming exercisable with respect to Shares having a fair market value exceeding the $100,000 limitation under Treasury RegulationSection 1.422-4, will be aNon-Qualified Stock Option.

ARTICLE X.

MISCELLANEOUS

10.1No Right to Employment or Other Status. No person will have any claim or right to be granted an Award, and the grant of an Award will not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan or any Award, except as expressly provided in an Award Agreement.

10.2No Rights as Stockholder; Certificates. Subject to the Award Agreement, no Participant or Designated Beneficiary will have any rights as a stockholder with respect to any Shares to be distributed under an Award until becoming the record holder of such Shares. Notwithstanding any other provision of the Plan, unless the Administrator otherwise determines or Applicable Laws require, the Company will not be required to deliver to any Participant certificates evidencing Shares issued in connection with any Award and instead such Shares may be recorded in the books of the Company (or, as applicable, its transfer agent or stock plan administrator). The Company may place legends on stock certificates issued under the Plan that the Administrator deems necessary or appropriate to comply with Applicable Laws.

10.3Effective Date and Term of Plan; Effect of Restatement. The Plan was initially adopted by the Board on March 22, 2016 (the “Effective Date”) and, unless earlier terminated by the Board, will remain in effect until the tenth anniversary of the Effective Date, but Awards previously granted may extend beyond that date in accordance with the Plan. The Restatement shall become effective on the later of the date that it is approved by the Board or the date that it is approved by the Company’s stockholders (the “Restatement Effective Date). From and after the Restatement Effective Date, the Plan, as restated by the Restatement, shall govern all Awards hereunder, including Awards granted prior to the Restatement Effective Date, provided, however, that to the extent that any provision of the Plan as in effect after the Restatement conflicts with a term of the Plan as in effect prior to the Restatement and the Restatement would adversely affect a Participant’s rights with respect to an Award granted prior to the Restatement Effective Date, the terms of the Plan as in effect prior to the Restatement shall control (but only to such extent).

10.4Amendment of Plan. The Administrator may amend, suspend or terminate the Plan at any time; provided that no amendment, other than an increase to the Overall Share Limit, may materially and adversely affect any Award outstanding at the time of such amendment without the affected Participant’s consent. No Awards may be granted under the Plan during any suspension period or after Plan termination. Awards outstanding at the time of any Plan suspension or termination will continue to be governed by the Plan and the Award Agreement, as in effect before such suspension or termination. The Board will obtain stockholder approval of any Plan amendment to the extent necessary to comply with Applicable Laws.

A-9

10.5Provisions for Foreign Participants. The Administrator may modify Awards granted to Participants who are foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters.

10.6Section 409A.

(a)General. The Company intends that all Awards be structured to comply with, or be exempt from, Section 409A, such that no adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Participant’s consent, amend this Plan or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any such actions intended to (A) exempt this Plan or any Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an Award’s grant date. The Company makes no representations or warranties as to an Award’s tax treatment under Section 409A or otherwise. The Company will have no obligation under this Section 10.6 or otherwise to avoid the taxes, penalties or interest under Section 409A with respect to any Award and will have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant “nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A.

(b)Separation from Service. If an Award constitutes “nonqualified deferred compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s Service Provider relationship will, to the extent necessary to avoid taxes under Section 409A, be made only upon the Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the Participant’s Service Provider relationship. For purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms means a “separation from service.”

(c)Payments to Specified Employees. Notwithstanding any contrary provision in the Plan or any Award Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A and as the Administrator determines) due to his or her “separation from service” will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for thesix-month period immediately following such “separation from service” (or, if earlier, until the specified employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following suchsix-month period or as soon as administratively practicable thereafter (without interest). Any payments of “nonqualified deferred compensation” under such Award payable more than six months following the Participant’s “separation from service” will be paid at the time or times the payments are otherwise scheduled to be made.

10.7Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a director, officer, other employee or agent of the Company or any Subsidiary will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan or any Award, and such individual will not be personally liable with respect to the Plan because of any contract or other instrument executed in his or her capacity as an Administrator, director, officer, other employee or agent of the Company or any Subsidiary. The Company will indemnify and hold harmless each director, officer, other employee and agent of the Company or any Subsidiary that has been or will be granted or delegated any duty or power relating to the Plan’s administration or interpretation, against any cost or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval) arising from any act or omission concerning this Plan unless arising from such person’s own fraud or bad faith.

A-10

10.8Lock-Up Period. The Company may, at the request of any underwriter representative or otherwise, in connection with registering the offering of any Company securities under the Securities Act, prohibit Participants from, directly or indirectly, selling or otherwise transferring any Shares or other Company securities, whether subject to outstanding Awards or otherwise, during a period of up to one hundred eighty days following the effective date of a Company registration statement filed under the Securities Act, or such longer period as determined by the underwriter (the “Lock-Up Period”). The Company may impose stop-transfer instructions with respect to Shares subject to the foregoing prohibitions until the end of theLock-Up Period and these restrictions will be binding on the applicable Participant. Further, each Participant shall, if so requested by any underwriter representative, execute a customarylock-up agreement which shall provide such terms as such underwriter representative may in its discretion request, including, without limitation the prohibition on sale and transfer during theLock-Up Period described in this Section 10.8.

10.9Data Privacy. As a condition for receiving any Award, each Participant explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its Subsidiaries and affiliates exclusively for implementing, administering and managing the Participant’s participation in the Plan. The Company and its Subsidiaries and affiliates may hold certain personal information about a Participant, including the Participant’s name, address and telephone number; birthdate; social security, insurance number or other identification number; salary; nationality; job title(s); any Shares held in the Company or its Subsidiaries and affiliates; and Award details, to implement, manage and administer the Plan and Awards (the “Data”). The Company and its Subsidiaries and affiliates may transfer the Data amongst themselves as necessary to implement, administer and manage a Participant’s participation in the Plan, and the Company and its Subsidiaries and affiliates may transfer the Data to third parties assisting the Company with Plan implementation, administration and management. These recipients may be located in the Participant’s country, or elsewhere, and the Participant’s country may have different data privacy laws and protections than the recipients’ country. By accepting an Award, each Participant authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, to implement, administer and manage the Participant’s participation in the Plan, including any required Data transfer to a broker or other third party with whom the Company or the Participant may elect to deposit any Shares. The Data related to a Participant will be held only as long as necessary to implement, administer, and manage the Participant’s participation in the Plan. A Participant may, at any time, view the Data that the Company holds regarding such Participant, request additional information about the storage and processing of the Data regarding such Participant, recommend any necessary corrections to the Data regarding the Participant or refuse or withdraw the consents in this Section 10.9 in writing, without cost, by contacting the local human resources representative. The Company may cancel Participant’s ability to participate in the Plan and, in the Administrator’s discretion, the Participant may forfeit any outstanding Awards if the Participant refuses or withdraws the consents in this Section 10.9. For more information on the consequences of refusing or withdrawing consent, Participants may contact their local human resources representative.

10.10Severability. If any portion of the Plan or any action taken under it is held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be null and void.

10.11Governing Documents. If any contradiction occurs between the Plan and any Award Agreement or other written agreement between a Participant and the Company (or any Subsidiary) that the Administrator has approved, the Plan will govern, unless it is expressly specified in such Award Agreement or other written document that a specific provision of the Plan will not apply.

10.12Governing Law. The Plan and all Awards will be governed by and interpreted in accordance with the laws of the State of Delaware, disregarding any state’schoice-of-law principles requiring the application of a jurisdiction’s laws other than the State of Delaware.

A-11

10.13Claw-back Provisions. All Awards (including any proceeds, gains or other economic benefit the Participant actually or constructively receives upon receipt or exercise of any Award or the receipt or resale of any Shares underlying the Award) will be subject to any Company claw-back policy, including any claw-back policy adopted to comply with Applicable Laws (including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder) as set forth in such claw-back policy or the Award Agreement.

10.14Titles and Headings. The titles and headings in the Plan are for convenience of reference only and, if any conflict, the Plan’s text, rather than such titles or headings, will control.

10.15Conformity to Securities Laws. Participant acknowledges that the Plan is intended to conform to the extent necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws. To the extent Applicable Laws permit, the Plan and all Award Agreements will be deemed amended as necessary to conform to Applicable Laws.

10.16Relationship to Other Benefits. No payment under the Plan will be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except as expressly provided in writing in such other plan or an agreement thereunder.

10.17Broker-Assisted Sales. In the event of a broker-assisted sale of Shares in connection with the payment of amounts owed by a Participant under or with respect to the Plan or Awards, including amounts to be paid under the final sentence of Section 9.5: (a) any Shares to be sold through the broker-assisted sale will be sold on the day the payment first becomes due, or as soon thereafter as practicable; (b) such Shares may be sold as part of a block trade with other Participants in the Plan in which all participants receive an average price; (c) the applicable Participant will be responsible for all broker’s fees and other costs of sale, and by accepting an Award, each Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any such sale; (d) to the extent the Company or its designee receives proceeds of such sale that exceed the amount owed, the Company will pay such excess in cash to the applicable Participant as soon as reasonably practicable; (e) the Company and its designees are under no obligation to arrange for such sale at any particular price; and (f) in the event the proceeds of such sale are insufficient to satisfy the Participant’s applicable obligation, the Participant may be required to pay immediately upon demand to the Company or its designee an amount in cash sufficient to satisfy any remaining portion of the Participant’s obligation.
