Carter Pate chose not to stand for re-election to the Board at the 2021 annual meeting.

Proxies cannot be voted for a greater number of persons than the number of nominees named.

RELATED PARTY TRANSACTIONS
On May 5, 2017, the Board adopted a Tax Asset Protection Plan (the "TAPP") in an effortSince January 1, 2021, there were no related person transactions. The charter of our Audit Committee requires all related person transactions to protect stockholder value by attempting to diminish the risk that the Company may be limited to its ability to use its net operating lossesreviewed and general business credit carry-overs (collectively, the "Tax Attributes") to reduce potential future federal income tax obligations. If the Company experiences an "ownership change," as defined in Section 382 of the Internal Revenue Code, its ability to use the Tax Attributes may be substantially limited, and the timing of the usage of the Tax Attributes could be substantially delayed, which could therefore significantly impair the value of that asset. The TAPP is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s Common Stock without the approval of the Board. The Board may, in its sole discretion, exempt any person from triggering the shareholder rights described in the TAPP.
On April 8, 2020, the Board approved the Third Amendment to the TAPP ("Third Amendment") that amended the TAPP, as previously amended by the First and Second Amendments that were approved by the Board on April 6, 2018 and April 5, 2019, respectively. The Third Amendment amended the definition of "Final Expiration Date" under the TAPP to extend the duration of the TAPP and makes associated changes in connection therewith. At our 2020 annual meeting of stockholders, our stockholders approved the Third Amendment, thus the Final Expiration Date will be the close of business on December 31, 2021.Audit Committee.
Gilbert Li, a director of the Company, is the Co-Founder and Managing Partner of Alta Fundamental Advisers ("Alta"), a private investment company that beneficially owned as of March 31, 2021 approximately 10.51% of the Company's outstanding Common Stock. In each of 2018 and 2019, Alta requested an exemption under the TAPP for the acquisition or ownership of outstanding common stock of the Company (individually, the "Alta Exemption Request") in order to purchase additional shares of Common Stock without triggering the shareholder rights described in the TAPP.
On November 6, 2018 and November 25, 2019, respectively, the Board, with Mr. Li abstaining, and the Audit Committee of the Board, approved each Alta Exemption Request and the related party transaction.
On February 27, 2019, the Board voted to increase the size of the Board from five directors to seven directors and appointed Brian Leen to the Board to fill one of the resulting vacancies effective February 27, 2019. Mr. Leen served as President and Chief Executive Officer of Carbon Solutions until December 7, 2018, the date of the Carbon Solutions Acquisition. 
In connection with the Carbon Solutions Acquisition, Mr. Leen's position with Carbon Solutions was eliminated.

EXECUTIVE COMPENSATION
COMPENSATION DISCUSSION AND ANALYSIS
In this Compensation Discussion and Analysis,section, we provide an analysis and explanation of our compensation program and the compensation earned by our named executive officers in the fiscal year ended December 31, 2020. Our2021. We are a "smaller reporting company" and the following compensation disclosures are intended to comply with the requirements applicable to smaller reporting companies. Although the rules allow us to provide less detail about its executive compensation program, our Compensation Committee is charged with establishingcommitted to providing the Company's philosophy forinformation necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe the 2021 executive compensation and approval, oversight, implementation and administration of executive compensation and benefits. Generally, the President and Chief Executive Officer of the Company makes recommendations to the Compensation Committee regarding executive compensation other thanprogram for himself; however, authority to approve compensation, performance goals and objectives for allour named executive officers is vested in the Compensation Committee.
For compensation awarded in 2020, in addition to extensive communications among its members, the Compensation Committee reviewed a report provided by its independent compensation consultant (LB & Co.), including market compensation analysis and peer group compensation data. Further, the Compensation Committee reviewed recommendations made by the Company's management for performance, experience and retention and was supported by generally available market data.
Overview - Executive compensation philosophy
Our philosophy for executive compensation is set forth in a document entitled "Executive Compensation Philosophy and Objectives" (the "EC Philosophy") adopted by the Compensation Committee on January 2, 2014. The EC Philosophy, which our Compensation Committee continues to follow, is designed to support achievement of our strategies and goals, thereby creating long-term value for our stockholders and customers and ensuring our ability to recruit and retain highly qualified executive employees. Our EC Philosophy:

Supports the Company's vision, mission, strategy, and values to generate profitability and sustained growth in the long-term best interests of our stockholders;
Aligns executive compensation with measures of performance tied to the strategic and operational performance of the business and stockholder returns;
Rewards executives on the basis of merit for individually and collectively achieving a leadership culture, innovation and excellence within the Company, and delivering sustained high performance to the Company, taking into consideration each executive's qualifications, level of responsibility and contribution to the Company's long-term performance;
Encourages competency-building by linking career development, performance management and compensation rewards;
Attracts and retains the best executive talent and a highly qualified diverse workforce within a non-discriminatory, merit-based compensation program; and
Uses external compensation data to benchmark comparable positions in similar industries and companies within our geographical region as one key factor in establishing the competitiveness of our executive salaries, incentives and benefits.
Our Compensation Committee has made incentive cash bonuses and long-term equity incentive awards consistent with the EC Philosophy. The long-term equity incentive awards are made under our 2017 Omnibus Incentive Plan (the "2017 Plan"). We believe that our compensation policies and practices do not motivate excessive or imprudent risk-taking. We note the following key aspects of our compensation policies and practices in making this determination:
The Company's EC Philosophy is based on balanced performance metrics that promote disciplined progress towards long-term Company goals in addition to the short-term health of the organization;
We do not offer significant short-term incentives that might drive high-risk investments at the expense of long-term Company value; and
The Company's compensation programs are weighted towards offering long-term incentives.
Because of these factors, we believe that our compensation policies and practices, both for our employees and our executive officers, do not create risks that are reasonably likely to have a material adverse effect on the Company.
The Company provides its stockholders with the opportunity to cast an advisory vote on annual executive compensation (a "say-on-pay proposal"). At the Company’s Annual Meeting in 2020, approximately 95.3% of the votes cast on the say-on-pay advisory vote regarding the executive compensation for the fiscal year ended December 31, 2019 were in favor of the proposal, which the Compensation Committee reviewed in assessing executive compensation for the fiscal year ending December 31, 2020. Proposal 2 included in the Proxy Statement is a say-on-pay advisory vote regarding the executive compensation for the fiscal year ending December 31, 2020 as described in this Proxy Statement. The Compensation Committee will continue to
20


consider the results of the Company's say-on-pay votes when making future compensation decisions for the Company's executive officers, including named executive officers.
On February 25, 2021 and April 9, 2021, respectively, the Compensation Committee adopted objectives and related performance metrics to the Long-Term Incentive Plan ("LTIP") and Executive Short-Term Incentive Plan ("ESTIP") documents that are within the EC Philosophy. While the philosophy has not changed, the incentives for our executive officers were updated in order to promote progress towards long-term Company goals in addition to the short-term health of the organization.
Independent Compensation Consultant
For compensation related to 2020 and beyond, the Compensation Committee retained LB & Co., to provide a market analysis of the Company’s executive and director compensation relative to our peer companies and to recommend the amount and form of such compensation to be paid in the future. LB & Co. compared the compensation practices of the Company to 17 peer group companies from a number of similar industries, including Commodity Chemicals, Environmental and Facility Services, Fertilizers and Agricultural Chemicals, Industrial Machinery, Oil and Gas Equipment and Services, Oil and Gas Refining and Marketing, and Specialty Chemicals. The Compensation Committee reviewed these peer companies and approved their use for comparison to the Company.

Base Salaries
Base salary is defined as ongoing, cash compensation paid bi-weekly based on such factors as job responsibilities, external competitiveness, and the individual's experience and performance. Pay ranges have been set based on the market where the Company competes for similar positions, with consideration given for employees serving similar functions in comparable companies. Base salary is typically increased annually based on performance and cost of labor/living increases. With the use of market data, the Compensation Committee considers the size of and whether to grant merit increases based on data from comparable companies, as well as review of an officer's annual performance and meeting of objectives. The Company attempts to ensure middle market pay for solid performers and to consider higher levels of pay for outstanding performers. The Company does not intend to be a market leader in base compensation.

Incentive Compensation
The Company uses incentive compensation in the form of cash, stock and other equity awards to motivate executives and align executive and stockholder interests. Incentive amounts are set based on job position and market practices. Incentives paid are subject to payroll taxes and other customary withholdings.
The Short-Term Incentive Plan ("STIP") is designed to motivate executives to achieve critical short-term goals, typically within a twelve-month period, that are expected to contribute to the long-term health and value of the Company. Incentives may be paid in cash or equity as determined by the Compensation Committee. The Compensation Committee adopted the ESTIP in September 2015 to further establish terms and conditions for cash awards made under the STIP. The Compensation Committee makes STIP awards under the 2017 Plan and the ESTIP.
The LTIP is designed to align executives’ interests with those of the Company's stockholders and to provide consistency with the Compensation Committee's approach to performance-based pay. Equity awards are the primary long-term incentive instrument and may be in the form of RSAs or performance stock units ("PSUs"). Equity awards vest over time based on continuous service, or over time based on achievement of certain performance measures set by the Compensation Committee at the time of the grant, considering accounting and regulatory restrictions and the financial condition of the Company. Awards under the LTIP to a participant will typically be made 50% as RSAs and 50% as PSUs. PSUs are vested upon achievement, as certified by the Compensation Committee, of one or more performance measures measured over one to three years. The Company’s updated LTIP was adopted February 26, 2020. LTIP awards are made under the 2017 Plan. Generally, equity awards are granted on the same day that the Compensation Committee approves such award.
From time to time,Accounting, effective March 1, 2021. Subsequently, the Board or Compensation Committee may recognize exemplary performance of any executive with a cash or equity award. Exemplary performance is performance that the Board or Compensation Committee determines to have required significant effort and commitment and is determined to have had a significant positive impact on the current or future performance of the organization. No other payments were made in 2020 and 2019 except as set forth below under the "Additional Executive Compensation Awards" section.
The stock portions of the 2020 and 2019 incentive awards are shown below in the Summary Compensation table under the "Stock Awards" column. The cash portions of the 2020 and 2019 incentive awards, which are defined under the STIP, are shown below in the Summary Compensation table under the "Non-Equity Incentive Plan Compensation" column.

and executives from entering into any transaction relating to hedging ADES securities, including zero-cost collars or forward-sale transactions.
We maintained key person term insurance for our Former Chief Executive Officer in the amount of $5 million through his termination date of June 30, 2020. The policies may be assigned to the individuals upon termination of employment (other than for cause) whereupon the executive would be responsible for any premium payments. We maintain long term disability policies for executives of the Company for up to $174,000 per year.
Executives are encouraged to own a number of shares of our Common Stock equal to a value of at least one times their annual base salary. Ownership is calculated considering holdings of restricted stock and PSU's, whether or not such holdings have vested, private holdings, shares held in retirement accounts and other shares attributed to the executive in accordance with Section 16 of the Exchange Act. Holding of options to purchase shares of our Common Stock also will be considered in the ownership calculation by adding the value of the spread of in-the-money options to the total value of other holdings. Mr. Marken of the Company met the executive equity ownership guidelines as of December 31, 2020. Mr. Wong, a new NEO in 2019, and Ms. Fields, a new NEO in 2021, have generally a 3-year period in which to meet the executive equity ownership guidelines.
So long as the stock ownership guidelines are met, executives may sell unrestricted stock and may exercise vested stock options and sell shares of the Company's Common Stock to pay for the exercise price and withholding tax, except as otherwise provided for in the underlying stock option agreement. It is preferred that executives own shares of the Company's Common Stock for a period greater than twelve months before selling it. Executives are advised to seek pre-approval of any exercise of stock options or sale of shares of our Common Stock at least 30 days in advance or the executive must be engaged in a pre-announced program sale in compliance with federal securities laws. All executive stock transactions must be made in compliance with our insider trading policy.
Pursuant to Section 16(b) of the Exchange Act, executives leaving the Company are encouraged to hold their stock in the Company for at least six months after leaving the Company.
The Company's Profit Sharing Retirement Plan ("401(k) Plan") is available to all eligible employees, including NEOs. Beginning in 2018, the Company elected to make safe harbor nonelective contributions to eligible employees. Pursuant to the safe harbor nonelective contributions notice, we make contributions to each eligible employee's account in an amount equal to three percent of eligible compensation, and will continue to do so unless the 401(k) Plan is amended or terminated. Additionally, at the discretion of the Board, the Company may make contributions based on the profitability of the Company to those accounts. In 2020, we made our matching contributions in cash. No discretionary contributions were made to the 401(k) Plan in 2020 other than as discussed above.
Employee and Company contributions to the 401(k) Plan are 100% vested.

We anticipate that a representative of Moss Adams will be available at the Annual Meeting to respond to stockholder questions and will have the opportunity to make a statement at that time if the representative desires to do so.

PROPOSAL FOUR
APPROVAL OF ADVANCED EMISSIONS SOLUTIONS, INC. 2022 OMNIBUS INCENTIVE PLAN
The Board believes that attracting and retaining highly qualified officers and key employees, and motivating them to serve the Company and to expend maximum efforts are important to our continued growth and success. In this regard, equity, stock-based and cash-based awards have been and will continue to be an important element of our compensation program because they enable our officers and other key employees to acquire or increase their proprietary interest in the operations and future success of our Company, thereby promoting a close identity of interests between such individuals and our stockholders.
We currently maintain the Advanced Emissions Solutions, Inc. 2017 Omnibus Incentive Plan (the "2017 Plan"). The Board believes that equity, stock-based and cash-based awards to key employees, officers and non-employee directors serve the best interests of stockholders by promoting a long-term focus for such individuals to increase the value of our Common Stock. Accordingly, on March 15, 2022, the Board adopted, subject to stockholder approval, the Advanced Emissions Solutions, Inc. 2022 Omnibus Incentive Plan (the "2022 Plan"). If stockholder approval is obtained for the 2022 Plan, we will cease to grant awards under the 2017 Plan, but if our stockholders do not approve the 2022 Plan, we will continue to grant awards under the 2017 Plan until its termination date or until such time as no shares of Common Stock remain available for issuance thereunder.
As of March 25, 2022, there are 189,228 shares of Common Stock currently remaining available for awards under the 2017 Plan. As of March 25, 2022, a total of 944,882 shares of Common Stock were subject to outstanding awards under the 2017 Plan (assuming achievement of maximum performance with respect to outstanding PSUs), of which 297,182 are subject to outstanding PSUs with a weighted average remaining contractual term of 2.1 years. As of March 25, 2022, we had a total of 19,116,463 shares of Common Stock outstanding and the closing price per share of Common Stock as reported on the Nasdaq Global Market was $6.17.
The 2022 Plan provides for the grant of options (both nonqualified stock options ("NSOs") and incentive stock options ("ISOs"), stock appreciation rights ("SARs"), restricted stock, restricted stock units ("RSUs"), PSUs, and other stock-based awards and cash-based awards.
Burn Rate Analysis
We currently do not expect significant changes to our historical equity award granting process or award levels from what we have made under the 2017 Plan. We believe our burn rates for 2019-2021 under the 2017 Plan remain at reasonable levels as set forth in the table below.

Key Features and Best Practices of the 2022 Plan
The 2022 Plan contains a number of best practices aimed to protect stockholders and reflect good corporate governance principles, including the following:
No Repricing. The 2022 Plan prohibits the reduction of the exercise price or grant price for outstanding options or SARs and prohibits the surrender of outstanding options or SARs for cash or a new award with a lower or no exercise price or grant price, in each case, without the approve of our stockholders.
No Liberal Share Recycling. The 2022 Plan prohibits liberal share recycling on all awards.
31


No Dividends or Dividend Equivalents on Unvested Awards. Dividends and dividend equivalents on awards under the 2022 Plan accrue but will not be paid until the underlying award vests.
Director Compensation Limit. The 2022 Plan contains an annual limit on cash and equity-based compensation that may be paid or granted, whether under the 2022 Plan or otherwise, to non-employee directors of $350,000 (or $400,000 in a non-employee director’s first year of service or if the non-employee director is serving as chairman or lead director).
Clawback Provisions. Awards under the 2022 Plan will be subject to any clawback policy adopted by the Company and any other clawback or recoupment provisions set forth in any award agreement.
Term and Exercise Price Limits on Options and SARs. Options and SARs granted under the 2022 Plan are subject to a maximum term of 10 years and options and SARs may not be granted at a discount to the fair market value of our Common Stock on the date of grant.
Summary of the 2022 Plan
The following summary of the 2022 Plan is qualified by reference to the full text of the 2022 Plan, a copy of which is attached to this Proxy Statement as Appendix A.
Administration. The 2022 Plan is administered by our Compensation Committee or any committee designated by the Board consisting of two or more members of the Board, each of whom is intended to be a "non-employee director" within the meaning of Rule 16b-3 of the Exchange Act and an "independent director" under the Nasdaq Marketplace Rules (or the rules of any securities exchange on which the Common Stock is listed). For purposes of this summary of the 2022 Plan, the Compensation Committee or other designated committee will be referred to as the "Committee."
Subject to the terms and conditions of the 2022 Plan, the Committee is authorized to select participants who are employees, directors or consultants of the Company or its subsidiaries, determine the awards to be made, set terms and conditions of such awards, determine the form of award agreements, and establish performance goals for any performance period and determine whether such goals were satisfied. The Committee also has the authority, among other things, to: (i) amend the terms of any outstanding award, subject to the repricing restrictions described below, so long as such amendment does not adversely affect a participant’s rights without the participant’s written consent, (ii) construe and interpret the terms of the 2022 Plan and any award agreement and to decide all questions of fact arising in its application, and (iii) take such other action, not inconsistent with the terms of the 2022 Plan, as it deems appropriate.
Eligibility. Any employee, director, or consultant of the Company or its subsidiaries is eligible to receive awards under the 2022 Plan. As of the date of this Proxy Statement, there are currently four non-employee directors, three executive officers and approximately 142 other employees and zero consultants who are eligible under the 2022 Plan.
The 2022 Plan contains an annual limit on cash and equity-based compensation that may be paid or granted, whether under the 2022 Plan or otherwise, to non-employee directors of $350,000 (or $400,000 in a non-employee director’s first year of service or if the non-employee director is serving as chairman or lead director).
Shares Subject to the 2022 Plan. Subject to the adjustments upon changes in capitalization described below, 2,000,000 shares of Common Stock will be authorized for issuance of awards under the 2022 Plan, plus (i) any shares of Common Stock that remain available for grant under the 2017 Plan as of the date of stockholder approval of the 2022 Plan and (ii) any shares of Common Stock that become available for issuance under the 2022 Plan as described below. For purposes of determining the number of shares remaining available for issuance under the 2022 Plan, to the extent an award under the 2022 Plan or the 2017 Plan is canceled, expired, forfeited, settled in cash, settled by issuance of fewer shares than the number underlying the award, or otherwise terminated without delivery of shares to the participant, the shares retained or returned to the Company will again be available for grant under the 2022 Plan. However, shares withheld in payment of the exercise price or taxes relating to an award are not available for reissuance. Shares issued under the 2022 Plan may be authorized and unissued shares or treasury shares.
The number of shares authorized for issuance of awards is subject to adjustment in the event of any stock dividend, stock split, spin off, rights offering, recapitalization through a large, nonrecurring cash dividend, or in the event of any other change in corporate capitalization, such as a merger, consolidation, any reorganization or any partial or complete liquidation of the Company.
Types of Awards
Options and SARs: The Committee is authorized to grant options as either ISOs, which can result in potentially favorable tax treatment to the participant, or NSOs and SARs under the 2022 Plan. The exercise or grant price per share of Common Stock subject to a stock option or SAR must be at least the fair market value of the underlying stock at the date of grant; provided, however, that an ISO granted to a participant who is the holder of record of more than 10% of the Common Stock must have an exercise price of at least 110% of the fair market value of the underlying Common Stock at the date of grant. The term of each
32


option and SAR and the times at which each Stock Option or SAR shall be exercisable generally will be fixed by the Committee, except that no option or SAR will have a term exceeding 10 years; provided, however, that an ISO granted to a participant who is the holder of record of more than 10% of the Common Stock will have a term not exceeding five years. Upon the termination of employment with us, the ability to exercise vested options and SARs and the expiration of such options and SARs will be determined in the discretion of the Committee as set forth in the applicable award agreement.
Restricted Stock and RSUs: The Committee may grant shares of restricted stock or RSUs (representing a right to receive shares of Common Stock, a cash equivalent amount or combination thereof) under the 2022 Plan. The Committee determines in the award agreement the restriction period during which the restricted stock or the RSUs are subject to a substantial risk of forfeiture based upon the passage of time, the achievement of performance goals or the occurrence of other events determined by the Committee. The Committee may impose other conditions, including a requirement that the participant pay a specified amount to purchase each share of restricted stock, restrictions based upon the achievement of specific performance goals, time-based restrictions on vesting, or holding requirements or sale restrictions upon vesting. Each award agreement will set forth the extent to which participants shall have the right to retain unvested restricted stock or RSUs following termination of employment or service.
Unless otherwise determined by the Committee or set forth in an award agreement, participants holding restricted stock generally may vote the shares. The Committee may provide in an award agreement that the holder of restricted stock may receive any dividends paid; however, such dividends must be subject to the same vesting conditions as the underlying restricted stock. Participants holding RSUs will have no rights of stockholders. The Committee may provide in an award agreement that the holder of such RSUs will be entitled to receive dividend equivalents; however, such dividend equivalents must be subject to the same vesting conditions as the underlying RSUs.
PSUs: The Committee may grant PSUs under the 2022 Plan. The Committee determines in the award agreement the applicable performance periods and performance measures. Earned PSUs may be settled in shares of Common Stock, a cash equivalent amount or a combination thereof, as set forth in the award agreement. Each award agreement will set forth the extent to which participants will have the right to receive a payout with respect to their PSUs following termination of employment or service. Participants holding PSUs will have no rights of stockholders. The Committee may provide in an award agreement that the holder of such PSUs will be entitled to receive dividend equivalents; however, such dividend equivalents must be subject to the same vesting and performance conditions as the underlying PSUs.
Other Stock-Based and Cash-Based Awards: The Committee may adopt other incentive arrangements under which participants may acquire shares of Common Stock by purchase, grant or otherwise, or receive an award payable in cash or Common Stock the value of which may be determined in whole or in part based on the value of the Common Stock. The Committee may also adopt other incentive arrangements under which participants may be awarded cash payments.
Replacement Awards. Awards may be granted in replacement of outstanding awards previously granted by an entity acquired by the Company or an affiliate, or with which the Company or an affiliate combines, as permitted under the terms of the 2022 Plan.
Transferability. Under the 2022 Plan, ISOs may not be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution, and will be exercisable during a participant’s lifetime only by the participant. Other awards under the 2022 Plan will be transferable by will, by the laws of descent and distribution or, solely to the extent and in the manner authorized by the Committee, by transfer to members of the participant’s immediately family or pursuant to a qualified domestic relations order.
Adjustments and Change in Control.The 2022 Plan provides that, in the event of any non-reciprocal transaction between the Company and the stockholders of the Company that causes any change in our capital structure that effects an increase or decrease in the number of shares of our Common Stock without receipt of consideration, the maximum number of shares of Common Stock for which awards may be made under the 2022 Plan will be proportionately increased or decreased,and the number and kind of shares for which awards are outstanding may be proportionately increased or decreased. Any such adjustments will be in compliance with Section 409A of the Internal Revenue Code (the "Code").
Upon a change in control, outstanding awards will become fully vested and exercisable if such awards are not assumed, converted or replaced by the continuing entity. If such awards are assumed, converted or replaced by the continuing entity, then unless provided otherwise in an award agreement, such assumed, converted or replaced awards will vest in the event of a participant’s termination without cause or a resignation with good reason within 12 months following the change in control. In addition, the Committee will have the discretion to provide for the termination and cash-out of outstanding awards (and the cancellation for no payment for underwater options and SARs) upon a change in control.
Amendment and Termination. The Board may alter, amend, suspend or terminate the 2022 Plan at any time, subject to stockholder approval requirements under the Nasdaq listing standards or other applicable laws.
33


No Repricing. The 2022 Plan prohibits the reduction of the exercise price or grant price for outstanding options or SARs and prohibits the surrender of outstanding options or SARs for cash or a new award with a lower or no exercise price or grant price, in each case, without the approve of our stockholders.
Clawback. Awards under the 2022 Plan will be subject to any clawback policy adopted by the Company and any other clawback or recoupment provisions set forth in any award agreement.
Federal Tax Consequences of the 2022 Plan
The following is a summary of the U.S. federal income tax treatment applicable to us and the participants who receive awards under the 2022 Plan based on the federal income tax laws in effect on the date of this proxy statement. This summary is not intended to be exhaustive and does not address all matters relevant to a particular participant based on their specific circumstances. The summary expressly does not discuss the income tax laws of any state, municipality, or non-U.S. taxing jurisdiction, or the gift, estate, excise (including the rules applicable to deferred compensation under Section 409A of the Code), or other tax laws other than U.S. federal income tax law. Because individual circumstances may vary, we recommend that all participants to consult their own tax advisor concerning the tax implications of awards granted under the 2022 Plan.
Option Grants. Options granted under the 2022 Plan may be either ISOs, which satisfy the requirements of Section 422 of the Code, or NSOs, which are not intended to meet such requirements. The U.S. federal income tax treatment for the two types of options differs as follows:
Incentive Stock Options. No taxable income is recognized by the optionee at the time of the ISO grant, and no taxable income is recognized for ordinary income tax purposes at the time the ISO is exercised, although taxable income may arise at that time for alternative minimum tax purposes. Unless there is a disqualifying disposition, as described below, the optionee will recognize long-term capital gain in an amount equal to the excess of (i) the amount realized upon the sale or other disposition of the purchased shares over (ii) the exercise price paid for the shares. A disqualifying disposition occurs if the disposition is less than two years after the date of grant or less than one year after the exercise date. If there is a disqualifying disposition of the shares, then the excess of (i) the fair market value of those shares on the exercise date or (if less) the amount realized upon such sale or disposition over (ii) the exercise price paid for the shares will be taxable as ordinary income to the optionee. Any additional gain or loss recognized upon the disposition will be a capital gain or loss.
If the optionee makes a disqualifying disposition of the purchased shares, then we will be entitled to an income tax deduction, for the taxable year in which such disposition occurs, equal to the amount of ordinary income recognized by the optionee as a result of the disposition. We will not be entitled to any income tax deduction if the optionee makes a qualifying disposition of the shares.
Non-Statutory Options. No taxable income is recognized by an optionee upon the grant of an NSO. The optionee in general will recognize ordinary income, in the year in which the NSO is exercised, equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares, and the optionee will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the optionee with respect to the exercised non-statutory option.
SARs. No taxable income is recognized upon receipt of a SAR. The holder will recognize ordinary income in the year in which the SAR is exercised, in an amount equal to the excess of the fair market value of the underlying shares of Common Stock on the exercise date over the base price in effect for the exercised right, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder in connection with the exercise of the SAR.
Restricted Stock Awards. The recipient of unvested shares of Common Stock will not recognize any taxable income at the time those shares are issued but will have to report as ordinary income, as and when those shares subsequently vest, an amount equal to the excess of (i) the fair market value of the shares on the vesting date over (ii) the cash consideration (if any) paid for the shares. The recipient may, however, elect under Section 83(b) of the Code to include as ordinary income in the year the unvested shares are issued an amount equal to the excess of (a) the fair market value of those shares on the issue date over (b) the cash consideration (if any) paid for such shares. If the Section 83(b) election is made, the recipient will not recognize any additional income as and when the shares subsequently vest. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the recipient with respect to the unvested shares at the time such ordinary income is recognized by the recipient.
RSUs; PSUs; Other Stock-Based Awards; Other Cash-Based Awards. No taxable income is recognized upon receipt of RSUs, PSUs, other stock-based awards or other cash-based awards. The holder will recognize ordinary income in the year in which the shares or cash subject to the award are actually issued or in the year in which the award is settled in cash. The amount of that income will be equal to the fair market value of the shares on the date of issuance or the amount of the cash paid in settlement of the award, and the holder will be required to satisfy the tax withholding requirements applicable to the income. We will be
34


entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder at the time the shares are issued or the cash amount is paid.
Deductibility of Executive Compensation. Section 162(m) of the Code limits the deductibility for federal income tax purposes of certain compensation paid to any "covered employee" in excess of $1 million. For purposes of Section 162(m), the term “covered employee” includes any individual who serves as chief executive officer, chief financial officer or one of the other three most highly compensated executive officers for 2017 or any subsequent calendar year. It is expected that compensation deductions for any covered employee with respect to awards under the 2022 Plan will be subject to the $1 million annual deduction limitation. The Committee may grant awards under the 2022 Plan or otherwise that is or may become non-deductible when it believes doing so is in the best interests of the Company and our shareholders.
New Plan Benefits
As described above, the selection of participants who will receive awards under the 2022 Plan and the size and types of awards will be determined by the Committee in its discretion. Therefore, the amount of any future awards under the 2022 Plan is not yet determinable and it is not possible to predict the benefits or amounts that will be received by, or allocated to, particular individuals or groups of employees.

PROPOSAL FIVE
APPROVAL OF THE FOURTHFIFTH AMENDMENT TO THE COMPANY'S TAX ASSET PROTECTION PLAN
The Board is asking stockholders to approve the Tax Asset Protection Plan, as amended on April 6, 2018, April 5, 2019, and April 8, 2020, April 9, 2021 and March 15, 2022 (the "TAPP"). If our stockholders do not approve the TAPP at the 2021 Annual Meeting, the TAPP will expire on December 31, 2021.2022. This proposal will be deemed approved if the votes cast in favor of the proposal exceed the votes cast opposing the proposal.
Background
We believe that we have valuable tax attributes which are significant assets of the Company. As of December 31, 2020,2021, we had several domestic tax attributes, including federal net operating lossesemployer and general business credit carry-overs of approximately $93.9$86.1 million (the "Tax Assets"). Under the Internal Revenue Code and regulations promulgated by the U.S. Treasury Department, the Company may carry forward or otherwise utilize these Tax Assets in certain circumstances to offset any current and future taxable income and thus reduce the Company’s federal income tax liability, subject to certain requirements and restrictions. To the extent that the Tax Assets do not otherwise become limited, the Company believes that it will have available a significant amount of Tax Assets in future years, and therefore these Tax Assets could be a substantial asset to the Company.
Our ability to use the Tax Assets could be substantially limited or delayed, however, if we experience an "ownership change," as defined in Section 382 of the Internal Revenue Code. In general, an ownership change occurs if there is a cumulative change in the ownership of the Company by "5- percent shareholders" (as defined for purposes of Section 382 of the Internal Revenue Code) that exceeds 50 percentage points over an applicable testing period (which is generally a rolling three-year period). Accordingly, on May 5, 2017, after consultation with the Company’s legal and tax advisors, the Board adopted the TAPP in order to protect the Company’s ability to utilize its Tax Assets and on April 6, 2018, April 5, 2019, April 8, 2020, April 9, 2021 the Board amended the TAPP to extend the expiration thereof and on April 9, 2021March 15, 2022 the Board again amended the TAPP to further extend the expiration thereof.
Calculating whether an "ownership change" has occurred is subject to uncertainty. This uncertainty arises from the complexity and ambiguity inherent in Section 382 of the Internal Revenue Code, as well as limitations on the knowledge that any publicly traded company can have about the ownership of and transactions in its securities. We have analyzed the information available, along with various scenarios of possible future changes in ownership. In light of this analysis, we believe that, in the absence of the TAPP, it is possible that we could undergo a subsequent "ownership change" under Section 382 of the Internal Revenue Code, which would substantially reduce our ability to utilize the Tax Assets. We believe the continuation of the TAPP will serve the interests of all stockholders given the size of the Tax Assets and the potential loss of value should changes in our stock ownership occur that are sufficient to cause a 50 percentage point or greater "ownership change."
The TAPP is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s outstanding Common Stock without the approval of the Board. Stockholders who beneficially owned 4.99% or more of the Company’s outstanding Common Stock upon execution of the TAPP will not trigger the TAPP so long as they do not acquire beneficial ownership of additional shares of Common Stock. The Board may, in its sole discretion, also exempt any person from triggering the TAPP.
If the stockholders do not approve the TAPP, the TAPP will expire on December 31, 2021.2022. If the stockholders approve the TAPP, it will expire on the earlier of (a) December 31, 2022,2023, (b) the time at which the Rights (described below) are redeemed pursuant to the TAPP, (c) the time at which the Rights are exchanged in full pursuant to the TAPP, (d) the effective date of the repeal of both Section 382 and Section 383 of the Internal Revenue Code, or any successor provisions or replacement provisions, if the Board determines that the TAPP is no longer necessary for the preservation of tax benefits or (e) the beginning of a taxable year of the Company for which the Board determines that the Company has or will have no Tax Assets.
Summary of Terms of the TAPP
The following description of the terms of the TAPP does not purport to be complete and is qualified in its entirety by reference to the TAPP, which is attached as Annex AAppendix B and is incorporated herein by reference. We urge you to read carefully the TAPP in its entirety, as the discussion below is only a summary.
The Rights. On May 5, 2017, the Board declared a dividend of one preferred share purchase right (each, a "Right") for each outstanding share of Common Stock to stockholders of record as of the close of business on May 22, 2017. One Right is also issued together with each share of Common Stock issued after May 22, 2017 but before the Distribution Date (as defined below) and, in certain circumstances, after the Distribution Date. Subject to the terms, provisions and conditions of the TAPP, if the Rights become exercisable, each Right would initially represent the right to purchase from the Company one ten-thousandth of a share of the Company’s Series B Junior Participating Preferred Stock, par value $0.001 per share (the "Series B Preferred Stock") for a purchase price of $50.00 (the "Purchase Price"). If issued, each fractional share of Series B Preferred Stock would
33


give the stockholder approximately the same dividend, voting and liquidation rights as does one share of Common Stock.
36


However, prior to exercise, a Right does not give its holder any rights as a stockholder of the Company, including, without limitation, any dividend, voting or liquidation rights.
Initial Exercisability. The Rights will not be exercisable until the earlier of (i) ten business days after a public announcement that a person has become an "Acquiring Person" by acquiring beneficial ownership of 4.99% or more of the Company’s outstanding Common Stock, or, in the case of a person that had beneficial ownership of 4.99% or more of the Company’s outstanding Common Stock upon execution of the TAPP, by obtaining beneficial ownership of additional shares of Common Stock or (ii) ten business days (or such later date as may be specified by the Board prior to such time as any person becomes an Acquiring Person) after the commencement of a tender or exchange offer by or on behalf of a person that, if completed, would result in such person becoming an Acquiring Person.
The date that the Rights become exercisable is referred to as the "Distribution Date." Until the Distribution Date, Common Stock certificates or the ownership statements issued with respect to uncertificated shares of Common Stock will evidence the Rights. Any transfer of shares of Common Stock prior to the Distribution Date will also constitute a transfer of the associated Rights. After the Distribution Date, separate rights certificates will be issued and the Rights may be transferred other than in connection with the transfer of the underlying shares of Common Stock unless and until the Board has determined to effect an exchange pursuant to the TAPP (as described below).
Flip-In Event. In the event that a person becomes an Acquiring Person, each holder of a Right, other than Rights that are or, under certain circumstances, were beneficially owned by the Acquiring Person (which will thereupon become null and void), will thereafter have the right to receive upon exercise of a Right and payment of the Purchase Price, a number of shares of Common Stock having a market value of two times the Purchase Price.
Redemption. At any time until a person becomes an "Acquiring Person", the Board may redeem the Rights in whole, but not in part, at a price of $0.00001 per Right (the "Redemption Price"). The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish. Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.
Exchange. At any time after a person becomes an Acquiring Person, the Board may exchange the Rights (other than Rights that have become null and void), in whole or in part, at an exchange ratio of one share of Common Stock, or a fractional share of Series B Preferred Stock (or of a share of a similar class or series of the Company’s preferred stock having similar rights, preferences and privileges) of equivalent value, per Right (subject to adjustment). Immediately upon an exchange of any Rights, the right to exercise such Rights will terminate and the only right of the holders of Rights will be to receive the number of shares of Common Stock (or fractional share of Series B Preferred Stock or of a share of a similar class or series of the Company’s preferred stock having similar rights, preferences and privileges) equal to the number of such Rights held by such holder multiplied by the exchange ratio. The Board shall not be empowered to effect such exchange at any time after an Acquiring Person becomes the beneficial owner of 50% or more of the Company’s outstanding Common Stock.
Expiration. The Rights and the TAPP will expire on the earlier of (i) the close of business on the earlier of (a) December 31, 2022,2023, or (b) December 31, 20212022 if stockholder approval has not been obtained prior to such date, (ii) the time at which the Rights are redeemed pursuant to the TAPP, (iii) the time at which the Rights are exchanged in full pursuant to the TAPP, (iv) the effective date of the repeal of both Section 382 and Section 383 of the Internal Revenue Code, or any successor provisions or replacement provisions, if the Board determines that the TAPP is no longer necessary for the preservation of tax benefits or (v) the beginning of a taxable year of the Company for which the Board determines that the Company has or will have no tax benefits.
Anti-Dilution Provisions. The Board may adjust the Purchase Price, the number of shares of Series B Preferred Stock or other securities or assets issuable and the number of outstanding Rights to prevent dilution that may occur as a result of certain events, including among others, a stock dividend, a stock split or a reclassification of the Series B Preferred Stock or Common Stock. With certain exceptions, no adjustments to the Purchase Price will be required until cumulative adjustments amount to at least 1% of the Purchase Price.
Amendments. For so long as the Rights are redeemable, the Board may supplement or amend any provision of the TAPP in any respect without the approval of the holders of the Rights. From and after the time the Rights are no longer redeemable, the Board may supplement or amend the TAPP only to cure an ambiguity, to alter time period provisions, to correct inconsistent provisions, or to make any additional changes to the TAPP which the Company may deem necessary or desirable, but only to the extent that those changes do not impair or adversely affect any Rights holder (other than an Acquiring Person or any Affiliate or Associate of an Acquiring Person or certain of their transferees) and do not result in the Rights again becoming redeemable or the TAPP again becoming amendable other than in accordance with this sentence.

Certain Considerations Related to the TAPP
Our Board believes that protecting the Tax Assets is in the Company’s and our stockholders’ best interests. Nonetheless, we cannot eliminate the possibility that changes in our stock ownership will occur sufficient to cause an "ownership change" even if the TAPP is approved. You should consider the factors below when making your decision.
Future Use and Amount of the Tax Assets is Uncertain. Our use of the Tax Assets depends on our ability to generate taxable income in the future. We cannot assure you whether we will have taxable income in any applicable period or, if we do, whether such income will exceed any potential Section 382 limitation and therefore we cannot assure you that we will realize the full value of the Tax Assets.
Potential Challenge to the Tax Assets. The amount of the Tax Assets has not been audited or otherwise validated by the Internal Revenue Service (the "IRS"). The IRS could challenge the amount of the Tax Assets, which could result in an increase in our liability for income taxes. In addition, determining whether an “ownership change”"ownership change" has occurred is subject to uncertainty, both because of the complexity and ambiguity of the Section 382 provisions and because of limitations on the knowledge that any publicly traded company can have about the ownership of, and transactions in, its securities on a timely basis. Therefore, we cannot assure you that the IRS or other taxing authority will not claim that we experienced an “ownership change”"ownership change" and attempt to reduce the benefit of the Tax Assets even if the TAPP is in place.
Continued Risk of Ownership Change. Although the TAPP is intended to diminish the likelihood of an "ownership change" under Section 382 of the Internal Revenue Code, we cannot assure you that it will be effective. The amount by which our ownership may change in the future could, for example, be affected by purchases and sales of stock by stockholders and new issuances or repurchases of stock by us, should we choose to do so.
Potential Effects on Liquidity. The TAPP is intended to deter persons or groups of persons from acquiring beneficial ownership of shares of our Common Stock in excess of the specified limitation. A stockholder’s ability to dispose of our Common Stock may be limited if the TAPP reduces the number of persons willing to acquire our Common Stock or the amount they are willing to acquire.
Potential Impact on Value. The TAPP could negatively impact the value of our Common Stock by deterring persons or groups of persons from acquiring shares of our Common Stock, including in acquisitions for which some stockholders might receive a premium above market value.
Anti-Takeover Effect. Our Board adopted the TAPP to diminish the risk that our ability to use the Tax Assets to reduce potential federal income tax obligations becomes limited. Nonetheless, the TAPP may have an "anti-takeover effect" because it will deter a person or group of persons from acquiring beneficial ownership of 4.99% or more of our Common Stock or, in the case of persons or persons that already own 4.99% or more of our Common Stock, from acquiring any additional shares of our Common Stock. The TAPP could discourage a merger, tender offer or accumulations of substantial blocks of shares.
Board Recommendation
The Board recommends that you vote "FOR" the approval of the Company’s FourthFifth Amendment of the Tax Attributes Protection Plan.


DELINQUENT SECTION 16(A) REPORTS
Section 16(a) of the Exchange Act requires our officers, directors, and persons who beneficially own more than 10% of a registered class of our equity securities to file reports of ownership with the SEC. Officers, directors and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.
The Company is not aware of any unreported transactions for 2020.

OTHER MATTERS
The Board knows of no other business to be presented at the Annual Meeting. If other matters properly come before the Annual Meeting, to the extent permitted by law, the persons named in the accompanying form of proxy intend to vote on such other matters in accordance with their best judgment.
PROPOSALS OF STOCKHOLDERS FOR PRESENTATION AT THE NEXT ANNUAL MEETING OF STOCKHOLDERS
We anticipate that the next Annual Meetingannual meeting of Stockholdersstockholders for the Company will be held in June 2022.2023.
Any stockholder of record who desires to submit a proper proposal for inclusion in the proxy material related to the next Annual Meeting2023 annual meeting of Stockholdersstockholders pursuant to Rule 14a-8 of the Exchange Act or the Company's bylaws must do so in writing in care of Ted Sanders,Clay Smith, Interim General Counsel and Secretary, at 8051 E. Maplewood Ave., Ste. 210, Greenwood Village 80111 no later than December 31, 2021.November 29, 2022, provided, however, that the Company’s bylaws provide that if the date of the annual meeting has been changed by more than thirty (30) days from the date on which the previous year’s annual meeting was held, notice by the stockholder to be timely must be so received not later than the close of business on the later of one hundred twenty (120) calendar days in advance of such annual meeting or ten (10) calendar days following the date of public disclosure of the date of such meeting. If a stockholder intends to submit a proposal at the meeting2023 Annual Meeting of Stockholders that is not included in our Proxy Statement,corresponding proxy statement, and the stockholder fails to timely notify us prior to March 15, 2022 of such proposal, then to the extent permitted by law, the proxies appointed by our management would be allowed to use their discretionary voting authority when the proposal is raised at the Annual Meeting,next annual meeting, without any discussion of the matter in the Proxy Statement. The stockholder must disclose, among other items, certain information related to the business to be proposed at the meeting, its beneficial ownership in the Company and whether it is acting in concert with other stockholders or interested parties. For a complete list of information that stockholders must provide, see Section 2.03 of the Company's bylaws.
HOUSEHOLDING OF PROXY MATERIALS
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements, annual reports, or notices of internet availability of proxy materials with respect to two or more stockholders sharing the same address by delivering a single proxy statement, annual report, or notice of internet availability of proxy materials addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.
Brokers with account holders who are Company stockholders may be "householding" our proxy materials. A single proxy statement, annual report, or notice of internet availability of proxy materials may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you notify your broker or the Company that you no longer wish to participate in "householding."
If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate proxy statement, annual report, or notice of internet availability of proxy materials, you may (1) notify your broker, (2) direct your written request to: Advanced Emissions Solutions, Inc., Attn: Corporate Secretary, 8051 E. Maplewood Ave., Ste. 210, Greenwood Village 80111, Telephone: 888-822-8617 or (3) contact our Investor Relations department by telephone at 312-445-2870. Stockholders who currently receive multiple copies of the proxy statement, annual report, or notice of internet availability of proxy materials at their address and would like to request "householding" of their communications should contact their broker. In addition, the Company will deliver, upon written or oral request to the address or telephone number above, a separate copy of the proxy statement, annual report, or notice of internet availability of proxy materials promptly to any stockholder at a shared address to which a single copy of the documents was delivered.

ADVANCED EMISSIONS SOLUTIONS, INC.
2022 OMNIBUS INCENTIVE PLAN
(Approved by stockholders on [●], 2022)
1.ESTABLISHMENT, OBJECTIVES AND DURATION.
(a)Establishment of the Plan. Advanced Emissions Solutions, Inc. hereby establishes an incentive compensation plan to be known as the "Advanced Emissions Solutions, Inc. 2022 Omnibus Incentive Plan." The Plan permits the granting of Nonqualified Stock Options, Incentive Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance Stock Units, Other Stock-Based Awards and Cash-Based Awards. The Plan is effective as of March 15, 2022 (the "Effective Date"), subject to the approval of the Plan by the stockholders of the Company. Definitions of capitalized terms used in the Plan are contained in the attached Glossary, which is an integral part of the Plan.
(b)Objectives of the Plan. The objectives of the Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to Participants and to optimize the profitability and growth of the Company through incentives that are consistent with the Company’s goals and that link the personal interests of Participants to those of the Company’s stockholders. The Plan is further intended to provide flexibility to the Company in its ability to motivate, attract, and retain the services of Participants who make or are expected to make significant contributions to the Company’s success and to allow Participants to share in the success of the Company.
(c)Duration of the Plan. No Award may be granted under the Plan after the day immediately preceding the 10th anniversary of the Effective Date, or such earlier date as the Board shall determine. The Plan will remain in effect with respect to outstanding Awards until no Awards remain outstanding.
2.ADMINISTRATION OF THE PLAN.
(a)The Committee. The Plan shall be administered by the Compensation Committee of the Board or such other committee as the Board shall designate consisting of two or more members of the Board each of whom is intended to be a "non-employee director" within the meaning of Rule 16b-3 (or any successor rule) of the Exchange Act and an "independent director" under the Nasdaq Marketplace Rules or the rules of any securities exchange on which Shares are listed (such committee, the "Committee"). The members of the Committee shall be appointed from time to time by, and shall serve at the discretion of, the Board.
(b)Authority of the Committee. Subject to Applicable Laws and the provisions of the Plan (including any other powers given to the Committee hereunder), and except as otherwise provided by the Board, the Committee shall have full and final authority in its discretion to take all actions determined by the Committee to be necessary in the administration of the Plan, including discretion to:
i.select the Employees, Directors and Consultants to whom Awards may from time to time be granted hereunder;
ii.determine whether and to what extent Awards are granted hereunder;
iii.determine the size and types of Awards granted hereunder;
iv.approve forms of Award Agreement for use under the Plan;
v.determine the terms and conditions of any Award granted hereunder;
vi.establish performance goals and performance measures for any performance period, adjust performance goals or measures, or the assessment of any performance goals or measures, applicable to any Award, including to account for any unusual in nature or infrequently occurring items, and determine whether such goals or measures were satisfied;
vii.amend the terms of any outstanding Award granted under the Plan, provided that, except as otherwise provided in Section 17, no such amendment shall reduce the Exercise Price of outstanding Options or the grant price of outstanding SARs without the approval of the stockholders of the Company, and provided further, that any amendment that would materially and adversely affect the Participant’s rights under an outstanding vested Award without adequate compensation therefor shall not be made without the Participant’s written consent;
viii.construe and interpret the terms of the Plan and any Award Agreement entered into under the Plan, and to decide all questions of fact arising in its application; and
ix.take such other action, not inconsistent with the terms of the Plan, as the Committee deems appropriate.
41


FOURTHAs permitted by Applicable Laws, the Committee may delegate its authority as identified herein, including the power and authority to make Awards to Participants who are not "insiders" subject to Section 16(b) of the Exchange Act, pursuant to such conditions and limitations as the Committee may establish.
(c)Effect of Committee’s Decision. All decisions, determinations and interpretations of the Committee shall be final, binding and conclusive on all persons, including the Company, its Subsidiaries, its stockholders, Employees, Directors, Consultants and their estates and beneficiaries.
3.SHARES SUBJECT TO THE PLAN.
(a)Number of Shares Available for Grants. Subject to adjustment as provided in Section 17 hereof, the maximum number of Shares that may be issued pursuant to Awards under the Plan shall be 2,000,000 plus (i) any Shares that remain available for grant under the Prior Plan as of the date of stockholder approval of this Plan and (ii) any Shares that become available for issuance under the Plan pursuant to Section 3(b). The Shares to be issued pursuant to the Awards may be authorized but unissued Shares or treasury Shares.
(b)Availability of Shares. To the extent that an Award under the Plan or an award under the Prior Plan is canceled, expired, forfeited, settled in cash, settled by issuance of fewer Shares than the number underlying the Award, or otherwise terminated without delivery of Shares to the Participant, the Shares retained or returned to the Company will again be counted for purposes of determining the maximum number of Shares available for Awards under the Plan under Section 3(a). For purposes of clarity, Shares that are tendered or withheld in payment of all or part of the Exercise Price of an Award or in satisfaction of tax withholding obligations, shall not be included in or added to the number of Shares available for issuance under the Plan.
4.ELIGIBILITY AND PARTICIPATION.
(a)Eligibility. Persons eligible to participate in the Plan include all Employees, Directors and Consultants.
(b)Actual Participation. Subject to the provisions of the Plan, the Committee may, from time to time, select from all eligible Employees, Directors and Consultants, those to whom Awards shall be granted and shall determine the nature and amount of each Award. The Committee may establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable foreign jurisdictions and to afford Participants favorable treatment under such laws; provided, however, that no Award shall be granted under any such additional terms, conditions, rules or procedures with terms or conditions which are inconsistent with the provisions of the Plan.
(c)Limit on Director Compensation. The aggregate dollar value of equity-based compensation (based on the grant date fair value) and cash compensation granted under the Plan or otherwise to any Director shall not exceed $350,000 during any calendar year; provided, however, that in the calendar year in which a Director first joins the Board or during any calendar year in which a Director is designated as Chairman of the Board or Lead Director, the maximum aggregate dollar value of equity-based and cash compensation granted to the Director may be up to $400,000.
5.TYPES OF AWARDS.
(a)Type of Awards. Awards under the Plan may be in the form of Options (both Nonqualified Stock Options and Incentive Stock Options), Stock Appreciation Rights (SARs), Restricted Stock, Restricted Stock Units, Performance Stock Units, Other Stock-Based Awards and Cash-Based Awards.
(b)Designation of Award. Each Award shall be designated in the Award Agreement.
6.OPTIONS.
(a)Grant of Options. Subject to the terms and provisions of the Plan, Options may be granted to Participants in such number and upon such terms, and at any time and from time to time, as shall be determined by the Committee. Notwithstanding the preceding sentence, Incentive Stock Options may be granted only to eligible Employees.
(b)Award Agreement. Each Option grant shall be evidenced by an Award Agreement that shall specify the Exercise Price, the duration of the Option, the number of Shares to which the Option pertains, and such other provisions as the Committee shall determine including the Option vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment (cash, Shares, or other consideration) upon settlement of the Award, and payment contingencies. The Award Agreement also shall specify whether the Option is intended to be an Incentive Stock Option or a Nonqualified Stock Option. Options that are intended to be Incentive Stock Options shall be subject to the limitations set forth in Section 422 of the Code.
(c)Exercise Price. Except for Options adjusted pursuant to Section 17 herein, and replacement Options granted in connection with a merger, acquisition, reorganization or similar transaction, the Exercise Price for each grant of an Option shall not be less than 100% of the Fair Market Value of a Share on the date the Option is granted.
42


i.However, in the case of an Incentive Stock Option granted to a Participant who, at the time the Option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Subsidiary, the Exercise Price for each grant of an Option shall not be less than 110% of the Fair Market Value of a Share on the date the Option is granted.
ii.In addition, the aggregate Fair Market Value, as of the date of grant, of the Shares with respect to which an Incentive Stock Option first becomes exercisable during any calendar year may not exceed $100,000. For purposes of this $100,000 limit, the Participant’s Incentive Stock Options under this Plan and all other plans maintained by the Company and its Subsidiaries shall be aggregated. To the extent any Incentive Stock Option would exceed this $100,000 limit, the Incentive Stock Option shall afterwards be treated as a Nonqualified Stock Option for all purposes.
(d)Term of Options. The term of an Option granted under the Plan shall be determined by the Committee, in its sole discretion; provided, however, that such term shall not exceed 10 years. However, in the case of an Incentive Stock Option granted to a Participant who, at the time the Option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Subsidiary, the term of the Incentive Stock Option shall be five years from the date of grant thereof or such shorter term as may be provided in the Award Agreement.
(e)Exercise of Options. Options granted under this Section 6 shall be exercisable at such times and be subject to such restrictions and conditions as set forth in the Award Agreement and as the Committee shall in each instance approve, which need not be the same for each grant or for each Participant.
(f)Payments. Options granted under this Section 6 shall be exercised by the delivery of a written notice to the Company, setting forth the number of Shares with respect to which the Option is to be exercised and specifying the method of the Exercise Price. The Exercise Price of an Option shall be payable to the Company: (i) in cash or its equivalent, (ii) by tendering (either actually or constructively by attestation) Shares having an aggregate Fair Market Value at the time of exercise equal to the Exercise Price, (iii) in any other manner then permitted by the Committee, including a cashless exercise, or (iv) by a combination of any of the permitted methods of payment. The Committee may limit any method of payment, other than that specified under (i), for administrative convenience, to comply with Applicable Laws or otherwise.
(g)Restrictions on Share Transferability. The Committee may impose such restrictions on any Shares acquired pursuant to the exercise of an Option granted under this Section 6 as it may deem advisable, including restrictions under applicable federal securities laws, under the requirements of any stock exchange or market upon which such Shares are then listed and/or traded, and under any blue sky or state securities laws applicable to such Shares.
(h)Termination of Employment or Service. Each Participant’s Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option following termination of the Participant’s employment or, if the Participant is a Director or Consultant, service with the Company and its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all Options, and may reflect distinctions based on the reasons for termination of employment or service.
7.STOCK APPRECIATION RIGHTS.
(a)Grant of SARs. Subject to the terms and provisions of the Plan, SARs may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee.
(b)Award Agreement. Each SAR grant shall be evidenced by an Award Agreement that shall specify the grant price, the term of the SAR, and such other provisions as the Committee shall determine.
(c)Grant Price. The grant price of a SAR shall not be less than 100% of the Fair Market Value of a Share on the date of grant of the SAR; provided, however, that this limitation shall not apply to Awards that are adjusted pursuant to Section 17 herein.
(d)Term of SARs. The term of an SAR granted under the Plan shall be determined by the Committee, in its sole discretion; provided, however, that such term shall not exceed 10 years.
(e)Exercise of SARs. SARs may be exercised upon whatever terms and conditions the Committee, in its sole discretion, imposes upon them and sets forth in the Award Agreement.
(f)Payment of SAR Amount. Upon exercise of an SAR, a Participant shall be entitled to receive payment from the Company in an amount determined by multiplying:
(i)the difference between the Fair Market Value of a Share on the date of exercise over the grant price; by
(ii)the number of Shares with respect to which the SAR is exercised.
43


At the discretion of the Committee, the payment upon SAR exercise may be in cash, in Shares of equivalent value, or in some combination thereof.
(g)Termination of Employment or Service. Each SAR Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the SAR following termination of the Participant’s employment or, if the Participant is a Director or Consultant, service with the Company and its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all SARs, and may reflect distinctions based on the reasons for termination of employment or service.
8.RESTRICTED STOCK.
(a)Grant of Restricted Stock. Subject to the terms and provisions of the Plan, Restricted Stock may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee.
(b)Award Agreement. Each Restricted Stock grant shall be evidenced by an Award Agreement that shall specify the Period(s) of Restriction, the number of Shares of Restricted Stock granted, and such other provisions as the Committee shall determine.
(c)Period of Restriction and Other Restrictions. The Period of Restriction applicable to an Award of Restricted Stock may, at the discretion of the Committee, lapse on a pro-rated, graded, or cliff basis (as specified in an Award Agreement). The Committee shall impose such other conditions and/or restrictions on any Shares of Restricted Stock granted pursuant to the Plan as it may deem advisable including a requirement that Participants pay a stipulated purchase price for each Share of Restricted Stock, a requirement that the issuance of Shares of Restricted Stock be delayed, restrictions based upon the achievement of specific performance goals, additional time-based restrictions, and/or restrictions under Applicable Laws or under the requirements of any stock exchange or market upon which such Shares are listed or traded, or holding requirements or sale restrictions placed on the Shares by the Company upon vesting of such Restricted Stock. The Company may retain in its custody any certificate evidencing the Shares of Restricted Stock and place thereon a legend and institute stop-transfer orders on such Shares, and the Participant shall be obligated to sign any stock power requested by the Company relating to the Shares to give effect to the forfeiture provisions of the Restricted Stock.
(d)Removal of Restrictions. Subject to Applicable Laws, Restricted Stock shall become freely transferable by the Participant after the last day of the Period of Restriction applicable thereto. Once Restricted Stock is released from the restrictions, the Participant shall be entitled to receive a certificate or book entry on the Company’s records evidencing the Shares. The Committee may provide that settlement of Restricted Stock shall be deferred, on a mandatory basis or at the election of the Participant, in compliance with Applicable Laws, including Section 409A.
(e)Voting Rights. Unless otherwise determined by the Committee and set forth in a Participant’s Award Agreement, to the extent permitted or required by Applicable Laws, as determined by the Committee, Participants holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares during the Period of Restriction.
(f)Dividends and Other Distributions. Regular cash Dividends paid with respect to the Shares of Restricted Stock will be subject to the same restrictions on transferability and vesting as the Restricted Stock with respect to which they were paid, and such Dividends will be paid within 30 days following the full vesting of the Shares of Restricted Stock with respect to which such distributions were made.

47


from such limitations in connection with a Subsidiary Disposition, shall remain fully exercisable until the expiration or sooner termination of the Award.

(b)The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.
21.RIGHTS OF PARTICIPANTS.
(a)Continued Service.

23.LEGAL CONSTRUCTION.

(e)Non-Exclusive Plan. Neither the adoption of the Plan by the Board nor its submission to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board or a committee thereof to adopt such other incentive arrangements as it may deem desirable.
(f)Code Section 409A Compliance. To the extent applicable, it is intended that this Plan and any Awards granted hereunder be exempt from, or comply, with the requirements of Section 409A.

Notwithstanding anything in this Plan or Award granted hereunder to the contrary, in no event will the Committee provide for the deferral of settlement or vesting of any Award, on a mandatory basis or Participant elective basis, unless such deferral is documented in writing and administered in compliance with Section 409A. In no event shall the number, kinds, or Exercise Price of any Award granted hereunder be modified or extended if such modification or extension would result in a violation of Section 409A.
24.CLAWBACK. Awards granted under the Plan will be subject to recoupment in accordance with any clawback policy that the Company adopts or is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. In addition, the Committee may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Committee determines necessary or appropriate, including a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of misconduct. No recovery of compensation under such a clawback policy will be an event giving rise to a right to resign for “good reason” or be deemed a "constructive termination" (or any similar term) as such terms are used in any agreement between any Participant and the Company.
