We knowYou are being asked to approve the issuance of no other businessClass A Common Stock issuable upon the conversion of all shares of our Series A-1 Stock and Series A-2 Stock. Because that issuance of Class A Common Stock, together with the Class A Common Stock issuable upon the conversion of all outstanding shares of our Series B Convertible Preferred Stock, par value $0.001 per share (the “Series B Stock” and, together with the Series A Stock, the “Preferred Stock”), issued in connection with our June 15, 2017 acquisitions of certain oil and natural gas properties from SN Marquis LLC (“Marquis”), a subsidiary of Sanchez Energy Corporation (“Sanchez”), and from Battlecat Oil & Gas, LLC (“Battlecat”), equals 20% or more of our total issued and outstanding shares of Class A Common Stock, we are required to obtain shareholder approval prior to the issuance under applicable NASDAQ listing rules.

If our stockholders do not approve the issuance of Class A Common Stock, we will be presentedprohibited under NASDAQ listing rules from issuing shares of Class A Common Stock equal to or greater than 20% of our issued and outstanding shares. As a result, our Series A-2 Stock will not convert into Series A-1 Stock and will not be convertible into shares of Class A Common Stock. Further, under the terms of the Series A-2 Stock contained in the Certificate of Designations for that series of stock, if stockholder approval of the issuance of Class A Common Stock is not obtained before December 15, 2017, then the dividend rate payable on our Series A-2 Stock will automatically increase by 5% per annum for the quarterly period ending March 31, 2018, and will continue to increase by an additional 0.5% each quarter thereafter (up to a maximum of 20.0%) until stockholder approval is obtained.

PROPOSALS TO BE VOTED ON—PROPOSAL 11—APPROVAL OF THE ISSUANCE OF CLASS A COMMON STOCK ISSUABLE UPON CONVERSION OF SERIES A STOCK

ElectionBACKGROUND

On May 26, 2017, we entered into a securities purchase agreement (the “Original SPA”) with Chambers Energy Capital III, LP (“Chambers”), pursuant to which we agreed to sell to Chambers, in a private placement under the Securities Act of Directors1933, as amended, shares of our Series A-1 Stock and Series A-2 Stock for an aggregate purchase price of $78 million.

AtOn June 15, 2017, we amended and restated the Annual Meeting, eight (8) directors areOriginal SPA in its entirety by entering into the Chambers SPA. On the same day, we closed the transactions contemplated by the Chambers SPA and issued to be electedChambers 5,400 shares of Series A-1 Stock and 74,600 shares of Series A-2 Stock (the “Series A Preferred Issuance”). In connection with the Series A Preferred Issuance, on June 15, 2017, we filed with the Secretary of State of Delaware (i) a Certificate of Designations of Convertible Participating Preferred Stock, Series A-1 (the “Series A-1 Certificate of Designations”), and (ii) a Certificate of Designations of Convertible Participating Preferred Stock, Series A-2 (the “Series A-2 Certificate of Designations” and together with theSeries A-1 Certificate of Designations, each, a “Series A Certificate of Designations”), to, among other things, authorize and establish the rights and preferences of each series of Series A Stock.

REASONS FOR THE SERIES A PREFERRED ISSUANCE

The purpose of the Series A Preferred Issuance was to partially finance our acquisitions of certain oil and natural gas properties (the “Acquisitions”) from (i) Battlecat pursuant to a Purchase and Sale Agreement, dated as of May 25, 2017 (the “Original Battlecat PSA”), as amended by the Amendment to the Purchase and Sale Agreement, dated as of June 15, 2017, by and between Battlecat and the Company (the “Amendment to Battlecat PSA” and, as amended, the “Battlecat PSA”), and (ii) Marquis, pursuant to a Purchase and Sale Agreement, dated as of May 26, 2017 (the “Original Marquis PSA”), as amended by the Amendment to the Purchase and Sale Agreement, dated as of June 15, 2017, by and between the Company and Marquis (the “Amendment to Marquis PSA” and, as amended, the “Marquis PSA”). On June 15, 2017, we closed both Acquisitions and, as part of the consideration under each of the Battlecat PSA and the Marquis PSA, we issued 1,184,632 shares of Series B Stock to Battlecat and 1,500,000 shares of Series B Stock to Marquis, respectively (collectively, the “Series B Preferred Issuance”). On the same day, we filed with the Secretary of State of Delaware a Certificate of Designations of Series B Convertible Preferred Stock (the “Series B Certificate of Designations” and, collectively with the Series A Certificates of Designations, each, a “Certificate of Designation”) to, among other things, authorize and establish the rights and preferences of Series B Stock.

Under the Chambers SPA, we have agreed to use commercially reasonable efforts to hold office untila stockholder meeting and to obtain at such meeting stockholder approval of the Annualconversion of all shares of Series A Stock issued or issuable under the Chambers SPA (assuming maximum conversion rates as set forth in each of the Series A Certificates of Designations and that we elect to pay 12 quarters of dividends in kind or by increasing the stated value of each series of the Series A Stock in accordance with the terms of each of the Series A Certificates of Designations) into shares of our Class A Common Stock (the “Stockholder Approval”). We are asking stockholders to vote for the Stockholder Approval in this Proposal 1.

REASONS FOR SEEKING STOCKHOLDER APPROVAL

Our Class A Common Stock is listed on The NASDAQ Stock Market LLC (“NASDAQ”) and, therefore, we are subject to the NASDAQ Listing Rules. Under NASDAQ Listing Rule 5635(d)(2), stockholder approval is required for certain sales, issuances or potential issuances of our Class A Common Stock (or securities convertible into or exercisable for Class A Common Stock) equal to 20% or more of our Class A Common Stock or 20% or more of the voting power outstanding before such issuance for less than the greater of book or market

value of our Class A Common Stock. Because we had a total of 21,822,015 shares of Class A Common Stock outstanding prior to the Series A Preferred Issuance and the Series B Preferred Issuance, which, for purpose of complying with the NASDAQ Listing Rules, are considered related transactions, we are restricted by NASDAQ Listing Rule 5635(d)(2) from issuing 4,364,403 or more shares of Class A Common Stock (or securities convertible into or exercisable for Class A Common Stock) in a non-public offering without obtaining stockholder approval. Whether or not the Stockholder Approval is obtained, following the completion of the Special Meeting, (i) as provided in the Series A-1 Certificate of StockholdersDesignations, each outstanding share of Series A-1 Stock will be convertible into approximately 166.67 shares of Class A Common Stock, pursuant to the conversion ratio set forth in the Series A-1 Certificate of Designations, if converted as of the date of the Special Meeting, and (ii) as provided in the Series B Certificate of Designations, each outstanding share of Series B Stock will convert into one outstanding share of Class A Common Stock. Therefore, following completion of the Special Meeting, whether or not the Stockholder Approval is obtained, 2,684,632 shares of our Class A Common Stock will be heldissued as a result of the conversion of Series B Stock and up to 900,000 shares of our Class A Common Stock could be issued as a result of the conversion of Series A-1 Stock (if such shares were converted as of the date of the Special Meeting and disregarding any potential payments of dividends in 2018kind on the Series A Stock).

In addition, if the Stockholder Approval is obtained, upon such approval, each outstanding share of Series A-2 Stock will automatically convert into one share of Series A-1 Stock. Therefore, up to 12,433,333 additional shares of our Class A Common Stock could be issued upon the conversion of such shares ofSeries A-1 Stock (if such shares were converted as of the date of the Special Meeting and disregarding any potential payments of dividends in kind). Further, assuming that we elect to pay 12 quarters of dividends in kind or by increasing the stated value of each series of the Series A Stock in accordance with the terms of each of the Series A Certificates of Designations, as more fully described below, up to 17,532,272 shares of Class A Common Stock will be issuable upon the conversion of all Series A-1 Stock issued or issuable under the Chambers SPA (including shares of Series A-1 Stock into which shares ofSeries A-2 Stock will automatically convert upon the approval of Proposal 1). Because the combined shares of Class A Common Stock issuable upon conversion of (i) Series B Stock issued in connection with the Acquisitions and (ii) Series A Stock issued or issuable pursuant to the Chambers SPA would exceed 20% of our outstanding Class A Common Stock prior to the Series A Preferred Issuance and the Series B Preferred Issuance, the Series A-2 Stock cannot be converted into Series A-1 Stock until such director’s successortime as the Stockholder Approval is duly elected and qualified or until such director’s earlier death, resignation or removal.obtained. See “Descriptions of Preferred Stock—Effect of Proposal on Current Stockholders.”

DESCRIPTIONS OF PREFERRED STOCK

Each series of Preferred Stock is a greater numberclass of persons than the number of nominees named in this proposal.

Our Bylaws provide that the authorized number of directors may be changed by actionequity security of the BoardCompany. Each series of Series A Stock ranks senior to Class A Common Stock with respect to dividend rights and rights upon the liquidation, winding-up or dissolution of the stockholders. UnderCompany, and each series of Series A Stock initially has a stated value of $1,000 per share (the “Stated Value”). Series B Stock rankspari passu with Class A Common Stock with respect to dividend rights, but senior to Class A Common Stock with respect to rights upon the Board Representation Agreement further discussed below in “Corporate Governance—Board Composition”,liquidation, winding-up or dissolution of the Company.

As noted above, upon the completion of the Special Meeting, whether or not the Stockholder Approval is obtained, holders of Series A-1 Stock will immediately have the option to convert their shares of Series A-1 Stock into shares of Class A Common Stock at a per share rate (the “Conversion Rate”) equal to the Stated Value of such share divided by six, subject to certain share-ownership requirements, EF Realisation Company Limited (“EF Realisation”customary adjustments (the “Conversion Price”) has. Whether or not the right to designate a limited number of nominees for electionStockholder Approval is obtained, no later than two business days following the holding of the Board directors. EF Realisation currentlySpecial Meeting, each share of Series B Stock will automatically convert into one share of Class A Common Stock. If the

Stockholder Approval is obtained at the Special Meeting, each outstanding share of Series A-2 Stock will automatically convert into one share of Series A-1 Stock, subject to customary adjustments. If the Stockholder Approval is not obtained at the Special Meeting and has not otherwise been obtained by December 15, 2017, the right to designatedividend rate for Series A-2 Stock will automatically increase by 5% per annum for the dividend period ended on March 31, 2018 and by an additional 0.5% each quarter thereafter until the Stockholder Approval is obtained, up to a maximum dividend rate of 20.0% per annum.

Upon the completion of the Special Meeting, we will have the option to convert Series A-1 Stock to Class A Common Stock if the volume weighted average price of Class A Common Stock exceeds the following percentages of the Conversion Price for twenty out of thirty consecutive trading days: (i) 200%, if such mandatory conversion occurs prior to June 15, 2019, (ii) 175%, if such mandatory conversion occurs after June 15, 2019 but before June 15, 2020, and (iii) 150%, if such mandatory conversion occurs after June 15, 2020. If on June 15, 2024, the trailing 20-day volume weighted average price of our Class A Common Stock (the “Prevailing Price”) is equal to or greater than the Conversion Price then in effect, then each share of theSeries A-1 Stock then outstanding will automatically convert to Class A Common Stock at the then applicable Conversion Rate. Notwithstanding anything to the contrary in the foregoing, in no event will more than 1,678,089 shares of Class A Common Stock be issued in connection with the conversion of Series A-1 Stock prior to the Stockholder Approval, and such conversion will only occur to the extent it will not result in a violation of any NASDAQ Listing Rules, provided that we are taking commercially reasonable efforts to effect the issuance in compliance with such rules.

Holders of our Series A-1 Stock will be entitled to vote with holders of our Class A Common Stock on an as-converted basis upon the consummation of the Special Meeting, whether or not the Stockholder Approval is obtained. Holders of our Series A-2 Stock are entitled to vote with holders of our Series A-1 Stock on all matters submitted for a vote of holders of our Preferred Stock as a separate class. Holders of our Series B Stock have no voting rights, except that holders of each series of Preferred Stock are entitled to one vote per share on any matter on which holders of such applicable series are entitled to vote separately as a class and, for so long as shares of a particular series of Preferred Stock are outstanding, the affirmative vote or consent of holders of at least a majority of the outstanding shares of such series, voting together as a separate class, is necessary for effecting any amendment or modification to the certificate of incorporation or the applicable Certificate of Designations that would materially and adversely affect the relative rights, preferences, privileges or voting power of such series.

Holders of Series A Stock are entitled to cumulative dividends payable quarterly initially at a rate of 9% per annum (the “Dividend Rate”) in cash and, for any 12 quarters (“PIK Quarters”), at our option and in our sole discretion, (i) in the form of additional shares of the respective series of Series A Stock at a per share price equal to $975 or (ii) by increasing Stated Value, in lieu of cash. After the 12 PIK Quarters, if we fail to fully declare and pay dividends in cash, then the Dividend Rate for Series A Stock will automatically increase by 5.0% per annum for the next succeeding dividend period and then an additional 1.0% for each successive dividend period, up to a maximum Dividend Rate of 20.0% per annum, until we pay dividends at such increased rate fully in cash for two nomineesconsecutive quarters. Separately, if the Stockholder Approval has not been obtained by December 15, 2017, the Dividend Rate for Series A-2 Stock will automatically increase by 5% per annum for the dividend period ended on March 31, 2018 and has designated Dr. Christopher Rowlandby an additional 0.5% each quarter thereafter until the Stockholder Approval is obtained, up to a maximum Dividend Rate of 20.0% per annum. In addition to dividends rights described above, holders of all series of Preferred Stock will be entitled to receive dividends or distributions declared or paid on Class A Common Stock on an as-converted basis.

If on June 15, 2024, the Prevailing Price is less than the Conversion Price then in effect, the Dividend Rate for Series A-1 Stock will automatically increase to 20.0% per annum, payable only in cash, unless automatically converted as described above. However, we, at our option, may instead elect to exchange each share ofSeries A-1 Stock for our senior unsecured notes with a two-year maturity, a 9.0% per annum coupon payable semi-annually in cash, and John H. Murray for electiongoverned by terms substantially similar to our Board.most recent high yield indenture at that time.

After June 15, 2020, we may redeem shares of Series A Stock in cash at a per share amount equal to (i) 110% of the Stated Value, if the redemption occurs prior to June 15, 2021, (ii) 105% of the Stated Value, if the redemption occurs prior to June 15, 2022, and (iii) 100% of the Stated Value, if the redemption occurs after June 15, 2022, in each case, plus any unpaid dividends. If the Stockholder Approval is not obtained on or prior to June 15, 2024, the Company must redeem all outstanding shares of Series A-2 Stock at the Stated Value then in effect on June 15, 2024. If at any time after June 15, 2024 we fail to fully declare and pay a quarterly dividend in cash on Series A-1 Stock, then we must redeem in cash all outstanding Series A-1 Stock at the Stated Value then in effect.

Effect of Proposal on Current Stockholders

If you submitProposal 1 is approved and disregarding any potential payments of dividends in kind on the Series A Stock, 74,600 shares of Series A-2 Stock would convert into 74,600 shares of Series A-1 Stock, resulting in a proxy but do not indicate any voting instructions,total of 80,000 shares of Series A-1 Stock outstanding upon such approval. If all shares of Series A-1 Stock were then converted into shares of our Class A Common Stock immediately following the persons named as proxies will voteapproval of Proposal 1, 13,333,333 shares of Class A Common Stock would be issued to Chambers, representing approximately 54.4% of the currently outstanding shares of Class A Common Stock plus the shares of Class A Common Stock represented thereby forissuable upon the election as directorsconversion of the persons whose namescurrently outstanding shares of Series B Stock.

Further, if Proposal 1 is approved, and biographies appear below. Allif we elected to pay dividends on the Series A Stock in kind for 12 quarters, pursuant to the terms of the persons whose names and biographies appear below are currently servingSeries A Certificate of Designations, then approximately 17,532,272 shares of Class A Common Stock would be issued to Chambers upon the conversion of all shares of Series A-1 Stock, including those converted from shares of Series A-2 Stock as our directors. In the event anya result of such approval, representing approximately 71.5% 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 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 eight 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, 2017. 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, 2016. 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, 2018. 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.

This proposal requires the favorable vote of a majority of the votes cast affirmatively or negatively by holders of the Company’scurrently outstanding shares of Class A Common Stock. Abstentions are not considered to be votes cast and, accordingly, will have no effect onStock plus 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

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, 2016 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 Standards 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, 2016.

Independent Registered Public Accounting Firm Fees and Other Matters

The following table summarizes the fees of BDO USA, LLP, our independent registered public accounting firm, and its affiliates, billed to us for each of the last two fiscal years for audit services and billed to us in each of the last two fiscal years for other services:

AUDIT FEES

Audit fees consist of fees billed for the audit of our annual consolidated financial statements, the review of the interim consolidated financial statements, and related services that are normally provided in connection with registration statements. Such services can only be provided by our principal accountants.

AUDIT-RELATED FEES

There were no such fees incurred in 2016 or 2015.

TAX FEES

Tax fees consist of fees for professional services, including tax consulting, planning and compliance performed by BDO USA, LLP and its affiliates.

ALL OTHER FEES

We did not incur any other fees in 2016 or 2015.

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 Certificate of Incorporation Authorizing the Board to Issue up to 10,000,000 Shares of “Blank Check” Preferred Stock

Our Board has determined that it is advisable and in the best interests of the Company to amend our Certificate of Incorporation, as amended (the “Certificate of Incorporation”) to authorize the Board to issue by resolution, from time to time, up to 10,000,000 shares of a new class of preferred stock in one or more series. Approval of this amendment would enable our Board to prescribe the series and the number of the shares of each series of preferred stock and the voting powers, designations, preferences, limitations, restrictions and relative rights of the shares of each series of preferred stock. The Board believes that the complexity of modern business financing and acquisition transactions requires greater flexibility in the Company’s capital structure than now exists, and that authorizing the issuance of “blank check” preferred stock would provide the Company with greater flexibility with respect to the Company’s capital structure for purposes such as additional equity financing and acquisitions. No preferred stock is presently authorized by the Company’s Certificate of Incorporation.

The Board has therefore approved, and recommends that the stockholders approve, an amendment to our Certificate of Incorporation that deletes the current Article 4 in its entirety and inserts, in lieu thereof, a new Article 4 that will read in its entirety as follows (the “Amendment”):

“ARTICLE 4

The aggregate number of shares of all classes of capital stock that the Corporation shall have the authority to issue is 110,005,000 shares, consisting of (i) 100,000,000 shares of Class A Voting Common Stock $0.001 par value per share (the “Class A Voting Common Stock”), (ii) 5,000issuable upon the conversion of the currently outstanding shares of ClassSeries BNon-Voting Common Stock. As of the date of this definitive proxy statement, the Company expects to make dividend payments in kind to Chambers on the Series A-1 and Series A-2 Stock $0.001 par value per share (the “Class BNon-Voting Common Stock”) and (iii) 10,000,000 shares of Preferred Stock, $0.001 par value per share (the “Preferred Stock”).

Authority is hereby expressly granted to the Board of Directors from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by adopting a resolution or resolutions providing for the issuance of the shares thereof and by filing a certificate of designations relating thereto in accordance with the General Corporation Law of the State of Delaware, to determine and fix the number of shares of such series and such voting powers, full or limited, or no voting powers, and such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be stated and expressed in such resolutions, all to the fullest extent now or hereafter permitted by the General Corporation Law of the State of Delaware. The powers, preferences and relative, participating, optional and other special rights of each such series of Preferred Stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding. Without limiting the generality of the foregoing, the resolution or resolutions providing for the issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law.

Subject to the rights of the holders of any series of Preferred StockChambers pursuant to the terms of thisthe Series A-1 Certificate of Incorporation or any resolution or resolutions providing forDesignations such that the issuanceapplicable Dividend Rate were incrementally increased to 20% per annum, and then all shares of Series A-1 Stock, including those converted from shares of Series A-2 Stock as a result of such series of stock adopted by the Board of Directors, the number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law of the State of Delaware.”

The following shows the changes contained in the proposed Article 4 marked against the version of Article 4 that is currently in effect (new language is indicated by underlined text; language to be deleted is indicated by strikethrough):

2. Preferred Stock. Preferred Stock may be issued from time to time in one or more series, each of such series to have such terms as stated or expressed herein and inissuable upon the resolution or resolutions providing for the issue of such series adopted by the Board of Directors as hereinafter provided.

Authority is hereby expressly granted to the Board of Directors from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by adopting a resolution or resolutions providing for the issuanceconversion of the shares thereof and by filing a certificate of designations relating thereto in accordance with the General Corporation Law of the State of Delaware, to determine and fix the number ofcurrently outstanding shares of such series and such voting powers, full or limited, or no voting powers, and

PROPOSAL 3—AMENDMENT TO CERTIFICATE OF INCORPORATION

such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be stated and expressed in such resolutions, all to the fullest extent now or hereafter permitted by the General Corporation Law of the State of Delaware. The powers, preferences and relative, participating, optional and other special rights of each such series of Preferred Stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding. Without limiting the generality of the foregoing, the resolution or resolutions providing for the issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law.

Subject to the rights of the holders of any series of Preferred Stock pursuant to the terms of this Certificate of Incorporation or any resolution or resolutions providing for the issuance of such series of stock adopted by the Board of Directors, the number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law of the State of Delaware.”

EFFECTS OF THE AMENDMENTSeries B Stock.

The issuance of shares of our preferred stock may adversely affect the rights of the holders of our Class A Common Stock as described above will result in dilution, and Class B Common Stock (together, “Common Stock”). If the Amendment is approved by our stockholders, our Board will be authorized to issue shares of preferred stock with certain designations, rights, qualifications, preferences, limitations and terms, any of which may dilute the voting power and economic interest of the holders of our Common Stock. For example, in the absence of a proportionate increase in our earnings and book value, an increase in the aggregate number of outstanding shares caused by the issuance of our preferred stock would dilute the earnings per share and book value per share of all outstanding shares of our Common Stock. In addition, in a liquidation, the holders of our preferred stock may be entitled to receive a certain amount per share of our preferred stock before the holders of our Common Stock receive any distribution. In addition, the holders of our preferred stock may be entitled to vote and such votes may dilute the voting rights of the holders of our Common Stock when we seek to take corporate action. Our preferred stock also may be convertible into shares of either our Class A Common Stock or our Class B Common Stock. Furthermore, our preferred stock could be issued with certain preferences over the holders of our Common Stock with respect to dividends or the power to approve the declaration of a dividend. The aforementioned situations are only examples of how shares of our preferred stock, if issued, could result in:

In addition to financing purposes, we could also issue blank check preferred stock that may, depending on the terms of such series, make more difficult or discourage an attempt to obtain control of our Company by means of a merger, tender offer, proxy contest or other means. Such blank check preferred shares could be used to create voting or other impediments or to discourage persons seeking to gain control of our Company. For example, such shares could be privately placed with purchasers favorable to our Board, and our Board could authorize holders of a series of our preferred stock to vote either separately as a class or with the holders of our Common Stock on any merger, sale or exchange of assets by our Company or any other extraordinary corporate

PROPOSAL 3—AMENDMENT TO CERTIFICATE OF INCORPORATION

transaction. The existence of the additional authorized shares could have the effect of discouraging unsolicited takeover attempts. The issuance of new blank check preferred shares also could be used to dilute the stock ownership of a person or entity seeking to obtain control of our Company should our Board consider the action of such entity or person not to be in the best interest of our stockholders. The issuance of new blank check preferred shares also could be used to entrench current management or deter an attempt to replace our Board by diluting the number or rights of shares held by individuals seeking to control our Company by obtaining a certain number of seats on our Board.

The Company currently does not have any plans, proposals or arrangements to issue any shares of blank check preferred stock and the request for authorization for the Board to issue blank check preferred stock is not in response to any takeover attempt or any other expression of interest indicated by a third party.

Upon the effectiveness of a Certificate of Amendment setting forth the Amendment, the Board will have the express authority to execute and file a certificate of designation setting forth the series and the number of shares of each series of preferred stock and the voting powers, designations, preferences, limitations, restrictions and relative rights of the shares of each series of our preferred stock.

EFFECTIVE DATE OF THE AMENDMENT

If the Amendment is approved by stockholders, all other sections of the Certificate of Incorporation would be maintained in their current form. The Amendment would become effective upon the filing of a Certificate of Amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware, which the Company would do promptly after the Annual Meeting. In the event that the proposed Amendment is not approved by our stockholders at the Annual Meeting, the current Certificate of Incorporation would remain in effect in its entirety.

Our Board reserves the right, notwithstanding stockholder approval of the Amendment and without further action by our stockholders, not to proceed with the Amendment at any time before the effective date of the Certificate of Amendment setting forth the Amendment.

VOTES REQUIRED

This proposal requires the favorable vote of both:

Abstentions and brokernon-votes will have the same effect as votes against this proposal for each of the foregoing votes.

PURPOSE AND BACKGROUND FOR

PROPOSAL 2—APPROVAL OF AN ADJOURNMENT OF THE DETERMINATION OF ADDITIONAL SHARESSPECIAL MEETING

TheOur stockholders are being asked to consider and vote upon an adjournment of the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve Proposal 1 at the time of the Special Meeting. If Proposal 2 is approved, and the Special Meeting is adjourned because there are not sufficient votes to approve Proposal 1 at the time of the Special Meeting, the Board intends to solicit additional proxies in favor of Proposal 1, including from stockholders that have previously voted against Proposal 1. If Proposal 2 is not approved, the Board will not have the ability to adjourn the Special Meeting for the purpose of soliciting additional proxies if there are not sufficient votes to approve Proposal 1 at the A&R 2016 Plan is to enhancetime of the Special Meeting.

VOTE REQUIRED

This proposal requires the favorable vote of a majority of the votes cast affirmatively or negatively by holders of 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.

PROPOSAL 4—INCENTIVE PLAN AMENDMENT

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:

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:

PROPOSAL 4—INCENTIVE PLAN AMENDMENT

ADDITIONAL INFORMATION ABOUT THE A&R 2016 PLAN

As of December 31, 2016, there were no awards outstanding under the A&R 2016 Plan, other than stock options. As of December 31, 2016, there were approximately 191,750 shares subject to outstanding stock options (taking into account the forfeiture of options that expired unexercised on such date), which had a weighted average price of $15.00 and a weighted average remaining years to expiration of 0.5. The closing price of our Class A Common Stock as of March 29, 2017 was $4.75. 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

An aggregate of 2,200,000 shares of Class A Common StockStock. Abstentions and broker non-votes are not considered to be votes cast for the foregoing purpose, and, accordingly, 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 purchasedhave no effect 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 acquisitionoutcome 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.vote on this proposal.

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 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.

PROPOSAL 4—INCENTIVE PLAN AMENDMENT

Award Limits

The A&R 2016 Plan includes annual limits on awards that may be granted to any individual participant. For participants other thannon-employee directors, the maximum aggregate number of shares of Class A Common Stock with respect to all options and stock appreciation rights that may be granted to any one person is 750,000 shares per year and the maximum aggregate number of shares of Class A Common Stock with respect to all restricted stock, restricted stock units and other stock or cash based awards that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code that may be granted to any one person is 500,000 shares per year. The maximum aggregate amount that may be paid in cash with respect to one or more awards payable in cash and not denominated in shares to any one person is $5,000,000 per year. These numbers may be adjusted to take into account equity restructurings and certain other corporate transactions as described below. 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). Notwithstanding the foregoing, in no event will more than the authorized number of shares available for issuance under the A&R 2016 Plan be granted to any one person during any fiscal year of the Company.

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, 2016, approximately 53 employees and 6non-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.

PROPOSAL 4—INCENTIVE PLAN AMENDMENT

Performance-Based Awards

Although the Company has not adopted a policy that all compensation paid to executive officers must be deductible, the A&R 2016 Plan is also intended to allow us to provide performance-based compensation that will be tax deductible without regard to the limits of Section 162(m) of the Internal Revenue Code (the “Code”). Therefore, for purposes of Section 162(m) of the Code, the A&R 2016 Plan contains an approved list of performance criteria that may be used for purposes of granting awards that are intended to qualify as performance-based compensation under the Code, in the event the Company chooses to structure compensation in a manner that will satisfy the performance-based compensation exception to Section 162(m). The Code limits the deductions a publicly-held company can claim for compensation in excess of $1 million paid in a given year to its chief executive officer and certain of its other most highly-compensated executive officers (other than its chief financial officer) (these officers are generally referred to as the “covered employees”). Performance-based compensation that meets certain requirements is not counted against the $1 million deductibility cap. Stock options and stock appreciation rights that may be granted under the A&R 2016 Plan generally should qualify as performance-based compensation. Other awards that the Company may grant under the A&R 2016 Plan may qualify as performance-based compensation if the payment, retention or vesting of the award is subject to the achievement during a performance period of performance goals selected by the administrator of the A&R 2016 Plan. The administrator of the A&R 2016 Plan retains the discretion to set the level of performance for a given performance measure under a performance-based award. For such awards to qualify as performance-based compensation, they must be in amounts that are within the individual award limits set forth in the A&R 2016 Plan and stockholders must approve the material terms of the performance goals every five years. Nothing in the

PROPOSAL 4—INCENTIVE PLAN AMENDMENT

A&R 2016 Plan guarantees that incentive compensation that the Company pays to its covered employees will qualify as performance-based compensation for purposes of Section 162(m), but the A&R 2016 Plan is intended to permit the administrator to seek to structure incentive compensation to meet the performance-based compensation requirements if it chooses to do so. In addition, even where compensation programs are intended to qualify as performance-based compensation for purposes of Section 162(m), there can be no guarantee that the requirements of Section 162(m) will be satisfied and that all such compensation will be deductible.

In order to constitute qualified performance based compensation (“QPBC”) under Section 162(m), in addition to certain other requirements, the relevant amounts must be payable only upon the attainment ofpre-established, objective performance goals set by the plan administrator and linked to stockholder-approved performance criteria. The A&R 2016 Plan contains the below performance criteria to allow us to qualify awards as qualified performance-based compensation.

For purposes of the A&R 2016 Plan, one or more of the following performance criteria will be used in setting performance goals applicable to QPBC and may be used in setting performance goals applicable to other stock or cash based awards: 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 A&R 2016 Plan also permits the plan administrator to provide for objectively determinable adjustments to the applicable performance criteria in setting performance goals for QPBC awards.

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

PROPOSAL 4—INCENTIVE PLAN AMENDMENT

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. 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.

PROPOSAL 4—INCENTIVE PLAN AMENDMENT

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 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, unless the compensation is performance-based, is approved by the employer’s stockholders, and meets certain other criteria, as described above under the heading “—Performance-Based Awards.”

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. 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.

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 600 Bailey Avenue, Suite 200, Fort Worth, Texas, 76107.

BOARD COMPOSITION

Our Board currently consists of nine members: Frank D. Bracken, III, Henry B. Ellis, Bernard Lambilliotte, Daniel R. Lockwood, John H. Murray, Stephen H. Oglesby, 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. Bernard Lambilliotte has not been nominated forre-election at the Annual Meeting following the end of his current term.

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

DIRECTOR INDEPENDENCE

Henry B. Ellis, Stephen H. Oglesby, 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.

Prior to the offering of our Class A Common Stock that was completed on December 22, 2016 pursuant to a Registration Statement on FormS-1 (FileNo. 333-214265), which was declared effective on December 15, 2016 (the “2016 Common Stock Offering”), EF Realisation, through subsidiaries and/or affiliates, controlled a majority of the voting power of our outstanding Class A Common Stock. As a result, we were a “controlled company” under the NASDAQ Rules, and as such, we qualified for and had relied on exemptions from certain corporate governance requirements. Upon completion of the 2016 Common Stock Offering, EF Realisation ceased to own a majority of the shares of our outstanding Class A Common Stock and we ceased to be a “controlled company.”

CORPORATE GOVERNANCE

As a result, we are relying on the applicable transition periods provided by the NASDAQ Rules, pursuant to which our Board will be required to be composed of a majority of independent directors by December 22, 2017, and our Compensation Committee and our Nominating and Corporate Governance Committee were required to be comprised of a majority of independent directors by March 22, 2017 and will be required to be comprised entirely of independent directors by December 22, 2017.

Our Compensation Committee is currently comprised of a majority of independent directors. Our Nominating and Corporate Governance Committee is currently composed entirely of independent directors. The “controlled company” exemptions do not modify the independence requirements for our Audit and Risk Committee. Our Audit and Risk Committee is composed entirely of independent directors under the NASDAQ Rules and Rule10A-3 promulgated under the Exchange Act. As of April 13, 2017, all of our committees were in compliance under the applicable independence standards and transition requirements.

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 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. Henry B. Ellis, a director nominee elected to the Board in October 2016, and Randy L. Wolsey, a director nominee elected to the Board in January 2017, were each recommended by anon-management director. Stephen H. Oglesby, a director nominee elected to the Board in March 2017, was recommended by Frank Bracken, III, our Chief Executive Officer. Dr. Christopher Rowland, elected to the Board in January 2013, and John H. Murray, elected to the Board in October 2016, are director nominees designated by EF Realisation under the Board Representation Agreement.

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.

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

CORPORATE GOVERNANCE

with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, 600 Bailey Avenue, Suite 200, 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., 600 Bailey Avenue, Suite 200, 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 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.

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. In addition, we intend to post on our website all disclosures that are required by law or the NASDAQ Rules concerning any amendments to, or waivers from, any provision of the Code of Ethics.

ATTENDANCE BY MEMBERS OF THE BOARD OF DIRECTORS AT MEETINGS

There were 8 meetings of the Board during the fiscal year ended December 31, 2016. During the fiscal year ended December 31, 2016, 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 AnnualSpecial Meeting. Once director attended the 2016 Annual Meeting of Stockholders. Absent compelling circumstances, all directors are expected to attend future annual meetings.

Committees of the Board

Our Board has established three standing committees—Audit and Risk, Compensation and Nominating and Corporate Governance—each of which operates under a written charter that has been approved by our Board. The members of each of the Board committees and committee Chairs are set forth in the following chart:

AUDIT AND RISK COMMITTEE

Our Audit and Risk Committee’s responsibilities include, but are not limited to:

CORPORATE GOVERNANCE

The Audit and Risk Committee charter is available on our website at www.lonestarresources.com. The members of the Audit and Risk Committee are Mr. Ellis, Mr. Oglesby and Mr. Wolsey, all of whom meet the independence requirements under Rule10A-3 promulgated under the Exchange Act and the NASDAQ Rules, including those related to Audit and Risk Committee membership. Mr. Ellis serves as the Chairperson of the Audit and Risk Committee. The members of our Audit and Risk Committee meet the requirements for financial literacy under the applicable NASDAQ Rules. Our Board has determined that Mr. Ellis is an “audit committee financial expert” as defined by Item 407(d)(5)(ii) of RegulationS-K.

The Audit and Risk Committee met 1 time in 2016. Our Class A Common Stock was listed on The NASDAQ Stock Market in July 2016. We expect that the Audit and Risk Committee will meet at least quarterly as required under its charter going forward.

COMPENSATION COMMITTEE

Our Compensation Committee is responsible for, among other matters:

Pursuant to the Compensation Committee’s charter, which is available on our website atwww.lonestarreources.com, the Compensation Committee has the authority to retain or obtain the advice of compensation consultants, legal counsel and other advisors to assist in carrying out its responsibilities. The Compensation Committee may delegate its authority under its charter to a subcommittee as it deems appropriate from time to time. The Compensation Committee has the authority to conduct or authorize investigations into any matters within the scope of its responsibilities as it deems appropriate, including the authority to request any officer, employee or adviser of the Company to meet with the Compensation Committee or any advisers engaged by the Compensation Committee. In addition to the foregoing and other authority expressly delegated to the Compensation Committee in the charter, the Compensation Committee may also exercise any other powers and carry out any other responsibilities consistent with the charter, the purposes of the Compensation Committee, the Company’s bylaws and applicable NASDAQ Rules.

CORPORATE GOVERNANCE

The members of our Compensation Committee are Mr. Murray, Mr. Pinkerton, and Mr. Wolsey. Mr. Pinkerton serves as the Chairperson of the Compensation Committee. Each of Mr. Pinkerton and Mr. Wolsey qualifies as independent under the NASDAQ Rules, including the NASDAQ Rules regarding compensation committee membership. Due to his affiliation with Ecofin Limited, our Board has not determined that John H. Murray is independent under the foregoing independence standards.

The Compensation Committee has delegated to a subcommittee its authority and responsibility under the A&R 2016 Plan with respect to (i) the approval of acquisitions and dispositions of Company securities by officers and directors of the Company for purposes of Section 16 of the Exchange Act, and (ii) the approval of performance-based compensation for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code. The members of the subcommittee are Mr. Pinkerton and Mr. Wolsey.

The Compensation Committee has not engaged and management did not engage a compensation consultant in 2016. The Compensation Committee anticipates that it will engage a compensation consultant in 2017. While the Company’s executives will communicate with the Compensation Committee and the Board regarding executive compensation issues, the Company’s executive officers do not participate in final executive compensation decisions.

The Compensation Committee did not meet in 2016. Following our listing on The NASDAQ Stock Market in July 2016 and while we were a controlled company, executive compensation decisions were made based on the judgment and experience of the members of the Compensation Committee and with input from other members of the Board when determined appropriate. We expect that, going forward, the Compensation Committee will meet as required to fulfill its duties under its charter.

NOMINATING AND CORPORATE GOVERNANCE COMMITTEE

Our Nominating and Corporate Governance Committee’s responsibilities include:

The Nominating and Corporate Governance Committee charter is available on our website at www.lonestarresources.com. Our Nominating and Corporate Governance Committee consists of Mr. Ellis, Mr. Oglesby, and Mr. Pinkerton, with Mr. Pinkerton serving as the Chair. All members of our Nominating and Corporate Governance Committee qualify as independent under the NASDAQ Rules. The Nominating and Corporate Governance Committee has the authority to consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders.

The Nominating and Corporate Governance Committee did not meet in 2016. Following our listing on The NASDAQ Stock Market in July 2016 and while we were a controlled company, the Board handled decisions relating to the identification and nomination of director candidates in 2016. We expect that, going forward, the Nominating and Corporate Governance Committee will meet as required to fulfill its duties under its charter.

Executive and Director Compensation

EXECUTIVE COMPENSATION

Named Executive Officers

We are currently considered a “smaller reporting company” for purposes of the SEC’s executive compensation disclosure rules. In accordance with such rules, we are providing a Summary Compensation Table and an Outstanding Equity Awards at FiscalYear-End Table as well as narrative disclosures regarding our executive compensation program. The individuals covered by this executive compensation disclosure are our chief executive officer and our two other most highly compensated executive officers. For 2016, our named executive officers were:

Our compensation committee strives to align Lonestar’s compensation strategy with company performance and stockholder interests, and ensure that it is equitable for participants. Compensation for named executive officers includes a fixed component (consisting of base salaries, 401(k) plan contributions and other health and welfare benefits), discretionary annual cash bonus opportunities and long-term equity incentive awards, which prior to 2017 consisted of stock option grants.

Executive compensation policy

The objective of the executive compensation framework is to competitively and appropriately reward performance and results delivered. To this end, our compensation policy is intended to embody the following principles:

Approach to executive compensation

We broadly seek to position fixed compensation in line with similar oil and gas companies, although no specified peer group was used in setting compensation for 2016. Individual positioning of compensation depends on this positioning aspiration plus consideration of experience, individual performance and Lonestar’s circumstances. When setting compensation, we seek to establish an appropriate mix between fixed and variable compensation. None of our executive officers are parties to any employment, severance or other agreement providing for compensation in the event of a termination of their employment with us, other than customary indemnification agreements.

Fixed compensation: Base salary is designed to compensate for the value the individual provides to Lonestar, including the following:

EXECUTIVE AND DIRECTOR COMPENSATION

No base salary increases were made in 2016. In addition, U.S.-based executives receive health and welfare plan benefits, which are the same as those made available to all full-time salaried employees. 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 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.

Short-term incentives: Our executives are eligible to receive a discretionary annual cash bonus, which for 2016 will not be based on any specific performance metrics or criteria. As of the date of this proxy statement, annual bonuses for our named executives for 2016 have not yet been determined. We expect that annual bonuses, if any, will be determined and paid in the coming weeks and will generally be based on a subjective determination of Lonestar’s overall performance and the executive’s individual performance for 2016, as determined by the compensation committee.

Long-term incentives: Long-term incentive awards have historically been granted in the form of stock options under our equity incentive plans. The options granted under these plans are options to purchase shares of the Company’s Class A Common Stock and are designated as either “Class A options” or “Class B options” based on their vesting schedule. Class A options vested in substantially equal installments over a three-year period, unless there is a change in control or cessation of employment by redundancy or termination. In the event of such a change in control, redundancy or termination event, all Class A options would vest on the date of that change in control, redundancy or termination event. Class B options would only vest in the event of a change in control or cessation of employment by redundancy or termination. In 2016 we adopted our Amended and Restated 2016 Incentive Award Plan, which will govern our future incentive awards, but did not grant any long-term incentive awards to named executive officers in 2016. In future years, we expect that our long-term incentive awards may take other forms, such as restricted stock units, stock appreciation rights or other types of awards.

Employment Agreements: Each of the employment agreements to which our executives were a party expired as of December 31, 2015. Currently none of our executive officers are parties to any employment agreement or compensatory arrangement, other than customary indemnification agreements.

2016 SUMMARY COMPENSATION TABLE

Security Ownership of Certain Beneficial Owners and ManagementSECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information with respect to holdings of our Class A Common Stock, by (i) stockholders who beneficially owned more than 5%Series A-1 Stock, Series A-2 Stock, and Series B Stock as of September 1, 2017, and upon completion of the outstanding shares of our Class A Common Stock, and (ii) each of our directors (which includes all nominees), each of our named executive officers and all directors and executive officersSpecial Meeting, as a group as of March 31, 2017, unless otherwise indicated.further described in the table below. 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 21,822,015 shares of Class A Common Stock, 5,400 shares of Series A-1 Stock, 74,600 shares of Series A-2 Stock, and 2,684,632 shares of Series B Stock outstanding as of March 31, 2017.September 1, 2017, upon completion of the Special Meeting, or upon the approval of Proposal 1, as applicable (disregarding any potential payments of dividends in kind on Series A Stock, as such payments in kind are not in the control of the beneficial owner of such stock). In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares subject to options, restricted stock units, stock appreciation rights, warrants or other conversion privileges held by such person, that may be exercisable or settled for or converted into shares of Class A Common Stock subject to options, warrants or other rights held by such person that are currently exercisable or will become exercisable within 60 days of March 31,September 1, 2017 or within 60 days of the Special Meeting, as applicable, 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., 600 Bailey Avenue, Suite 200, Fort Worth, Texas, 76107.

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 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.

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) 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.

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.

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. 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).

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.

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 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.

8.2Corporate Transactions. In the event of any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation, repurchase, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Common Stock or other securities of the Company, Change in Control, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, other similar corporate transaction or event, other unusual or nonrecurring transaction or event affecting the Company or its financial statements or any change in any Applicable Laws or accounting principles, the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in Applicable Law or accounting principles may be made within a reasonable period of time after such change) and either automatically or upon the Participant’s request, is hereby authorized to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to (x) prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or event or (z) give effect to such changes in Applicable Laws or accounting principles:

(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 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 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% 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.

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.

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.

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.

10.18Section 162(m) Limitations.

(a)Individual Award Limitations. Notwithstanding any provision in the Plan to the contrary, and subject to adjustment as provided in Article VIII, (i) the maximum aggregate number of Shares with respect to one or more Awards of Options or Stock Appreciation Rights that may be granted to any one person during any fiscal year of the Company shall be 750,000; (ii) the maximum aggregate number of Shares with respect to one or more Awards of Restricted Stock, Restricted Stock Units, or Other Stock or Cash Based Awards that are intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code (“Performance-Based Compensation”) and are denominated in Shares that may be granted to any one person during any fiscal year of the Company shall be 500,000; and (iii) the maximum amount of cash that may be paid in cash to any one person during any fiscal year of the Company with respect to one or more Awards payable in

cash and not denominated in Shares shall be U.S. $5,000,000;provided,however, that in no event will more than the Overall Share Limit be granted to any one person during any fiscal year of the Company with respect to one or more Awards denominated in Shares. To the extent required by Section 162(m) of the Code, Shares subject to Awards which are canceled shall continue to be counted against the award limits above. Each of the limitations in this Section, other than the Overall Share Limit, shall be multiplied by two (2) with respect to Awards denominated in Shares granted to a Participant and Awards paid in cash to a Participant during the first fiscal year in which the Participant commences employment with the Company and/or its Subsidiaries.

(b)Committee Composition. To the extent an Award is intended to qualify as Performance-Based Compensation, the Administrator shall be a Committee and it is intended that each member of such Committee will be an “outside director” within the meaning of Section 162(m) of the Code.

(c)Performance-Based Compensation.The Administrator, in its sole discretion, may determine at the time an Award is granted or at any time thereafter whether such Award is intended to qualify as Performance-Based Compensation. For the avoidance of doubt, nothing herein shall require the Administrator to structure any Awards in a manner intended to constitute Performance-Based Compensation and the Administrator shall be free, in its sole discretion, to grant Awards that are not intended to be Performance-Based Compensation. Notwithstanding any other provision of the Plan and except as otherwise determined by the Administrator, any Award which is intended to qualify as Performance-Based Compensation shall be subject to any additional limitations set forth in Section 162(m) of the Code or any regulations or rulings issued thereunder that are requirements for qualification as Performance-Based Compensation, and the Plan and the applicable Award Agreement shall be deemed amended to the extent necessary to conform to such requirements. In addition, Awards of Restricted Stock, Restricted Stock Units and Other Stock or Cash Based Awards that are intended to qualify as Performance-Based Compensation shall be subject to the following provisions, which shall control over any conflicting provision in the Plan or any Award Agreement:

(i) To the extent necessary to comply with the requirements of Section 162(m)(4)(C) of the Code, no later than 90 days following the commencement of any performance period or any designated fiscal period or period of service (or such earlier time as may be required under Section 162(m) of the Code), the Administrator shall, in writing, (a) designate the Participant to receive such Award, (b) select the Performance Criteria applicable to the performance period, which Performance Criteria shall be limited to the specific performance goals set forth in the definition of Performance Criteria, (c) establish the performance goals (and any exclusions), and amounts of such Awards, as applicable, which may be earned for such performance period based on the Performance Criteria, and (d) specify the relationship between Performance Criteria and the performance goals and the amounts of such Awards, as applicable, to be earned by each Participant for such performance period.

(ii) Following the completion of each performance period, the Administrator shall certify in writing whether and the extent to which the applicable performance goals have been achieved for such performance period. In determining the amount earned under such Awards, the Administrator shall have the right to reduce or eliminate (but not to increase) the amount payable at a given level of performance to take into account additional factors that the Administrator may deem relevant, including the assessment of individual or corporate performance for the performance period.

(iii) Unless otherwise specified by the Administrator at the time of grant, the Performance Criteria with respect to an Award intended to be Performance-Based Compensation payable to a Participant shall be determined on the basis of Applicable Accounting Standards. For this purpose, “Applicable Accounting Standards” means the U.S. Generally Accepted Accounting Principles, International Financial Reporting Standards or other accounting principles or standards applicable to the Company’s financial statements under U.S. federal securities laws.

(iv) No adjustment or action described in Article VIII or in any other provision of the Plan shall be authorized to the extent that such adjustment or action would cause such Award to fail to so qualify as Performance-Based Compensation, unless the Administrator determines that the Award should not so qualify.
