PROPOSAL FOUR
APPROVAL OF AMENDMENT NO. 3, IN ACCORDANCE WITH SECTION 162(m) OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED, AND AMENDMENT NO. 4 TO THE COMPANY'S AMENDED AND RESTATED 2007 EQUITY INCENTIVE PLAN, AS AMENDED

At the 2016 Annual Meeting, we are requesting that stockholders approve, as a whole, Amendment No. 3 and Amendment No. 4 to the Company’s Amended and Restated 2007 Equity Incentive Plan, as amended (the "2007 Plan"). Amendment No. 3 addresses Section 162(m) of the Code, which limits the deductibility of performance-based compensation paid to the Company’s CEO and certain other executive officers, unless the plan under which the compensation is paid meets specified criteria, including, among other things, that stockholders approve the material terms of compensation that is subject to performance goals. Amendment No. 4 of the 2007 Plan proposes an increase to the individual annual award limits from 100,000 shares to 400,000 shares to effectuate the executive compensation decisions of the Company's Compensation Committee as discussed in the Additional Executive Compensation Plans section herein. The material terms of the 2007 Plan, other than the performance goal criteria contained in Amendment No. 3 and the increased individual limit contained in Amendment No. 4, were previously approved by our stockholders in 2007 and 2012. The Company is asking stockholders to approve Amendment No. 3 and Amendment No. 4 to the 2007 Plan in order to ensure deductibility of performance-based compensation in accordance with Section 162(m) of the Code and to effectuate the Board’s executive compensation plan as discussed herein. As proposed for approval and with the addition of specific performance goal criteria pursuant to Amendment No. 3, and the increase in the individual award limits pursuant to Amendment No. 4, the material terms of the 2007 Plan are substantially the same as previously approved by our stockholders in 2007 and 2012.

All share amounts in Proposal Four reflect the 2:1 stock split of the Company’s Common Stock on March 14, 2014.

Background

Our Board adopted, and our stockholders approved, the ADA-ES, Inc. 2007 Equity Incentive Plan (the “Original Plan”) in 2007. The Original Plan was further amended and restated as of August 31, 2010 to make non-material changes to assure Internal Revenue Code Section 409A compliance and to increase the non-management director annual grant limit to 30,000 shares of Common Stock from 20,000. In 2012, our Board adopted, and our stockholders approved, Amendment No. 1 to the 2007 Plan to increase the amount of authorized and issuable shares as well as the limits of shares that may be granted to individuals and directors. On August 6, 2013, the Board approved a General Amendment of Company Plans whereby Advanced Emissions Solutions, Inc. as successor to ADA, assumed the 2007 Plan. On February 12, 2014, our Compensation Committee approved and adopted Amendment No. 2 to the 2007 Plan to make non-material changes to specifically allow for cash awards, such as under the Short Term Incentive Plan, and establish certain procedures for such cash awards. In addition to cash awards, the 2007 Plan authorizes the issuance to employees, directors and consultants (each a “Grantee”) of up to a maximum of 3.6 million shares of Common Stock (each an “Award”). As of December 31, 2015, 493,491 options have been granted and 706,509 shares have been reserved but not yet issued under the 2007 Plan. Additional information about the 2007 Plan can be found in the Executive Compensation section of this Proxy Statement.

Summary of Amendment No. 3

Our Compensation Committee approved and adopted Amendment No. 3 to the 2007 Plan on February 12, 2014 and our Board approved Amendment No. 3 on February 13, 2014, subject to approval by our stockholders at our 2016 annual meeting. Amendment No. 3 is attached to this Proxy Statement as Annex I.

Under Section 162(m) of the Code, the Company may not deduct compensation paid to the Company’s CEO and certain other executive officers in excess of $1 million with respect to each such individual. Certain performance-based compensation paid to these individuals is not included within the $1 million limitation if it is paid pursuant to a plan that meets specified criteria, including stockholder approval. Briefly, with respect to performance-based compensation payable under the 2007 Plan, Code Section 162(m) requires:
compensation must be determined pursuant to an objective formula;
certification by the Compensation Committee that the performance goals in the formula have been satisfied; and
the stockholders of the Company have approved the material terms of the performance-based compensation, which include:
◦the eligible participants;
◦the maximum amount payable to any individual; and
◦the business criteria on which the performance goal(s) in the formula is based;


to ensure performance-based bonuses are fully deductible.

Amendment No. 3 amends the 2007 Plan to add specific performance goal criteria. Our Compensation Committee has reviewed the performance goal criteria it reasonably expects to utilize for “Performance-Based Compensation” under the 2007 Plan in the foreseeable future and such criteria is included in Amendment No. 3. Such criteria includes certain financial and stock value measures, either in absolute terms or on a comparison basis, for the Company on a consolidated basis, for one or more “Related Entities,” as defined in the 2007 Plan, such as a subsidiary of the Company, or for one or more divisions of the Company or a Related Entity.
Subject to the approval by the stockholders of Amendment No. 3, the Company will be entitled to a deduction equal to the amount of compensation that qualifies as “performance-based compensation” in accordance with Section 162(m) of the Code. However, if the proposal is not approved by stockholders and the Compensation Committee implements alternative methods of paying bonuses in lieu of compensation intended to be “Performance-Based Compensation” under the 2007 Plan, the future deductibility by the Company of any such bonuses may be limited by the $1 million cap on deductibility of compensation under Section 162(m) of the Code.
Eligible Participants
All executive employees who are eligible to receive Awards under the 2007 Plan are eligible to receive Performance-Based Compensation under the 2007 Plan, as specifically determined by the Compensation Committee from time to time. Under Code Section 162(m) no deduction is allowed in any taxable year for compensation in excess of $1 million paid to our chief executive officer and each of our four most highly paid other executive officers who are serving in such capacities as of the last day of such taxable year, and these five individuals are considered the “covered employees” with respect to whom the limitations could apply under Section 162(m) of the Code.
Maximum Amount Payable
The individual bonuses payable as Performance-Based Compensation pursuant to the 2007 Plan are determined from time to time by the Compensation Committee in its sole discretion and may vary among the various eligible participants. The maximum amount payable as Performance-Based Compensation pursuant to the 2007 Plan has been determined to be 200% of base salary with respect to short-term incentive Awards, and 250% of base salary with respect to long-term incentive Awards. The base salaries for the Company’s covered employees are set forth below under “Executive Compensation; Base Salaries.”
Maximum amounts approved by the Compensation Committee payable to our NEOs as Performance-Based Compensation pursuant to the 2007 Plan for previous years are described in the Executive Compensation section of this Proxy Statement.
Business Criteria on which Performance Goals are Based
The performance-based compensation payable to each participant is based on an individual bonus target(s) with respect to particular business criteria for the performance period set by the Compensation Committee in writing and is directly related to the satisfaction of the applicable performance goal(s) set by the Compensation Committee for such performance period. A performance goal is an objective formula or standard utilizing one or more of the following criteria related to the Company’s business and any objectively verifiable adjustment(s) thereto permitted and pre-established by the Compensation Committee in accordance with Code Section 162(m):

The following criteria for the Company on a consolidated basis, one or more related entities, and/or one or more divisions of the foregoing, either in absolute terms or compared to the performance of (x) the Company, its related entities or divisions (for a different period), (y) one or more other companies or (z) an index covering multiple companies:

net income
economic value added (earnings less a capital charge)
EBITDA (earnings before interest, taxes, depreciation and amortization)
sales
costs
gross margin
operating margin
pre-tax profit or income
market share
return on net assets
return on assets
return on capital

return on invested capital
cash flow
free cash flow
operating cash flow
operating income
earnings before interest and taxes
working capital
innovation as measured by a percentage of sales from new products
facility installations
technology advancements
product development
operational improvements
The following criteria for the Company, either in absolute terms or compared to the performance of (x) the Company (for a different period), (y) one or more other companies or (z) an index covering multiple companies:

stock price
return on stockholders’ equity
earnings per share
cash flow per share
total stockholder return (stock price appreciation plus dividends)
Future Performance-Based Awards
The bonus payable to a participant who is not a Code Section 162(m) covered employee may also be based on other factors (including subjective factors). The performance period(s) individual bonus target(s) and performance goal(s) will be adopted by the Compensation Committee in its sole discretion with respect to each performance period and, with respect to such covered employees, must be adopted no later than the latest time permitted by the Code in order for bonus payments pursuant to the 2007 Plan to be deductible under Code Section 162(m). Future performance-based awards under the 2007 Plan to our non-employee directors, executive officers and employees may be made at the discretion of the Compensation Committee or, with respect to awards not subject to Code Section 162(m), a committee consisting of Mr. Sampson and Mr. Simonton, subject to certain limitations. At this time, therefore, the compensation that may be received by our executive officers and other employees if our stockholders approve Amendment No. 3 to the 2007 Plan cannot be determined.

Summary of Amendment No. 4

The Board approved Amendment No. 4 to the 2007 Plan on June 5, 2015 subject to the approval of our stockholders. Amendment No. 4 is attached to this Proxy Statement as Annex II.

Under the NASDAQ Stock Market listing rules, the Company must get stockholder approval of the material terms of any equity compensation plan, including the maximum amount payable to any individual. Amendment No. 4 is an adjustment to the maximum number of shares payable to any individual, other than non-management directors, in a given year to 400,000 from 100,000.

The Board passed Amendment No. 4 in accordance with the Company’s EC Philosophy to create long-term value for our stockholders by aligning the interests of, and to retain, highly qualified executive employees (see discussion below under “Overview - Executive Compensation Philosophy” for more detail). With this philosophy in mind, on June 6, 2015, the Compensation Committee approved a grant of stock options and stock appreciation rights ("SAR's") to Mr. Sampson in recognition of his promotion to President and Chief Executive Officer.The majority of Mr. Sampson’s stock options are subject to stockholder approval of Amendment No. 4 to the 2007 Plan on or before June 5, 2017. The stock options subject to stockholder approval of Amendment No. 4 were granted in “tandem” with an equivalent number of SAR's, which only vest if the Stock Options expire as a result of Amendment No. 4 to the 2007 Plan not being approved by stockholders on or before June 5, 2017 (see the Executive Compensation section of this Proxy Statement for more details).

Summary of the 2007 Plan
The following summary of the 2007 Plan is qualified in its entirety by the specific language of the 2007 Plan, as filed as Exhibit 10.79 to the Company’s Form 10-Q filed with the U.S. Securities and Exchange Commission ("SEC") on November 12, 2010, and Amendment No. 1 to the 2007 Plan, as filed as Exhibit 10.53 to the Company’s Form 10-K for the fiscal year ended December 31, 2011 filed with the SEC on March 15, 2012, and Amendment No. 2 to the 2007 Plan, as filed

as Exhibit 10.1 to the Company's Form 8-K filed with the SEC on June 11, 2015, copies of which are available to any stockholder upon request, and which may also be viewed without charge on the SEC’s website at www.sec.gov(File No. 000-50216). Capitalized terms used but not defined below have the meanings set forth in the 2007 Plan.
General Description
The 2007 Plan permits grants of “Awards,” which include the grant of (1) options to purchase Common Stock (“Options”), (2) “restricted” shares of Common Stock (“Restricted Stock”), (3) Performance Share Units (“PSU's”), (4) cash awards and (5) other rights or benefits under the 2007 Plan. Under the 2007 Plan, incentive stock options (“ISO’s”), within the meaning of Section 422 of the Code, can be granted only to our employees or employees of any parent or subsidiary corporation. Non-qualified stock options (“NSO’s”) and Restricted Stock may be granted to employees, directors and consultants. An Award may include any combination of Options or Restricted Stock depending on the status of the recipient.
The 2007 Plan provides for the grant of Options with exercise terms that include a fixed exercise price (i.e., the price an optionee must pay for the stock issued on exercise of the Option), which is related to the market price of our Common Stock on the date of grant. The exercise price is required to be no less than the fair market value of the Common Stock at that time, except in the case of owners of 10% or more of our Common Stock at the time of a grant, in which case the exercise price will be no less than 110% of the per share fair market value of the Common Stock. In addition, Awards of Options and Restricted Stock will be subject to a vesting schedule or, in the case of Restricted Stock, a “reverse” vesting schedule, which may be based on the passage of time, the occurrence of one or more events, the satisfaction of performance criteria or other conditions.
Under the 2007 Plan, we may grant Awards to such employees, directors or consultants who are residing in foreign jurisdictions as the administrator of the 2007 Plan may determine from time to time. The 2007 Plan is not a qualifying deferred compensation plan under Section 401(a) of the Code and is not subject to the provision of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).
Shares Reserved
As of January1, 2016, the number of shares of Common Stock authorized for issuance under the 2007 Plan is limited to not more than 706,509 shares, which includes shares of Common Stock that may be issued upon exercise of Options or as Restricted Stock issued under the 2007 Plan. The 2007 Plan includes an “evergreen” provision pursuant to which additional shares reserved for issuance are automatically added to the 2007 Plan on the first day of each fiscal year, beginning with the fiscal year commencing January 1, 2008, in an amount equal to ten percent (10%) of the increase in the total number of shares of Common Stock outstanding on the last day of the immediately preceding fiscal year over the number of outstanding shares of Common Stock on such date one year prior, or such lesser number of shares as is later ratified by the Board at their first meeting or action in such new fiscal year. In no event may any annual increase exceed 600,000 shares and as currently in effect, in no event can the total number of shares authorized for issuance under the 2007 Plan exceed 3,600,000.
Administration
The 2007 Plan is administered by a “Plan Administrator,” which may be the Board or a committee designated by the Board in such a manner as to satisfy applicable laws. With respect to grants to directors or employees who are also officers or directors of the Company, such grants and related transactions under the 2007 Plan are generally exempt from Section 16(b) of the Exchange Act in accordance with Rule 16b-3. With respect to awards to covered employees subject to Section 162(m) of the Code, the committee will be comprised solely of two or more “outside directors” as defined under Section 162(m) and applicable tax regulations. For grants of awards to individuals not subject to Rule 16b-3 and Section 162(m), our Board may authorize one or more officers to grant such awards. The Board has authorized our Compensation Committee to serve as the Plan Administrator and, with respect to awards not subject to Code Section 162(m), has also authorized a committee consisting of Mr. Sampson and Mr. Simonton to grant Awards under the 2007 Plan, subject to certain limitations.
Limitations on Award Grants
The maximum number of shares of Common Stock that may be granted as to an Award to any grantee in any fiscal year is currently limited to 100,000 shares, except for Non-Management Directors, who may be granted annual Awards covering up to 50,000 shares. However, in connection with his or her initial commencement of services with us, a participant in the 2007 Plan who is an employee may be granted up to an additional 100,000 shares, which do not count against the limit set forth in the previous statement. These limitations ensure that any Options granted under the 2007 Plan qualify as “performance-based compensation” under Section 162(m) of the Code. Under Code Section 162(m) no deduction is allowed in any taxable year for compensation in excess of $1 million paid to our chief executive officer and each of our four most highly paid other executive officers who are serving in such capacities as of the last day of such taxable year. An exception to this rule applies to compensation that is paid pursuant to a stock incentive plan approved by our stockholders and that specifies, among other things, the maximum number of shares with respect to which options may be granted to eligible employees under such plan

during a specified period. Compensation paid pursuant to options granted under such a plan and with an exercise price equal to the fair market value of our Common Stock on the date of grant is deemed to be inherently performance-based, since such awards provide value to employees only if the stock price appreciates. If the 2007 Plan did not contain the Code Section 162(m) share limits with respect to which options may be granted to eligible employees during a specified period, any compensation expense associated with the Options granted under the 2007 Plan in excess of $1 million for any of our five highest paid officers would not be deductible to us under the Code.
Amendment and Termination
Our Board may at any time amend, suspend or terminate the 2007 Plan. To the extent necessary to comply with applicable provisions of federal securities laws, state corporate and securities laws, the Code, the rules of any applicable stock exchange or national market system and the rules of any foreign jurisdiction applicable to awards granted to residents therein, we will obtain stockholder approval of any amendment to the 2007 Plan in such a manner and to such a degree as required.
The 2007 Plan will terminate as of June 18, 2017, ten years from the date the 2007 Plan was approved by our Board, unless previously terminated by the Board.
Section 409A
We intend that awards granted under the 2007 Plan will not constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code or otherwise comply with or be exempt from Code Section 409A. If any award were deemed to be nonqualified deferred compensation for such purposes, the award would have to satisfy the requirements of Section 409A to avoid adverse tax consequences to the recipient of the award. These requirements could include limitations on election timing, acceleration of payments, and distributions. We may amend the Plan or individual awards in the future if it were needed to avoid such tax consequences.
Other Terms of Options
Options granted under the 2007 Plan and the rights and privileges evidenced by any Option may not be transferred, assigned, pledged or hypothecated in any manner (whether by operation of law or otherwise) other than (i) by will or by the applicable laws of descent and distribution, (ii) pursuant to a qualified domestic relations order as defined in Section 414(p) of the Code, or Title I of ERISA or the rules thereunder or (iii) as otherwise determined by the Plan Administrator and set forth in the applicable Option agreement. Any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of any Option under the 2007 Plan or of any right or privilege conferred thereby, contrary to the Code or to the provisions of the 2007 Plan, or the sale or levy or any attachment or similar process upon the rights and privileges conferred thereby shall be null and void. The designation by an Optionee of a beneficiary does not, in and of itself, constitute an impermissible transfer under the 2007 Plan.
If the Optionee’s relationship with the Company or any related corporation ceases for any reason other than termination for cause, death or total disability, and unless by its terms the Option sooner terminates or expires, then the Optionee may exercise, for a three-month period, that portion of the Optionee’s Option which is exercisable at the time of such cessation, but the Optionee’s Option shall terminate at the end of the three-month period following such cessation as to all shares for which it has not previously been exercised, unless, in the case of an NSO, such provision is waived in the agreement evidencing the Option or by resolution adopted by the Plan Administrator within 90 days of such cessation. If, in the case of an ISO, an Optionee’s relationship with the Company or related corporation changes (i.e., from employee to non-employee, such as a consultant), such change shall constitute a termination of an Optionee’s employment with the Company or related corporation and the Optionee’s ISO will become an NSO.
Options under the 2007 Plan must be issued within 10 years from the effective date of the 2007 Plan, which occurred on June 19, 2007. Options granted under the 2007 Plan cannot be exercised more than 10 years from the date of grant. Options issued to a 10% Stockholder are limited to a five-year exercise period.
Payment of the option exercise price (and any applicable withholding taxes) is generally made in full at the time the notice of exercise of the Option is delivered to the Company and is in cash, bank certified or cashier’s check or personal check (unless at the time of exercise the Plan Administrator in a particular case determines not to accept a personal check). The Plan Administrator can determine at the time the Option is granted for ISO’s, or at any time before exercise for NSO’s, that additional forms of payment will be permitted. To the extent permitted by the Plan Administrator and applicable laws and regulations (including, but not limited to, federal tax and securities laws and regulations and state corporate law), an Option may be exercised by delivery of shares of stock of the Company held by an Optionee having a fair market value equal to the exercise price, such fair market value to be determined in good faith by the Plan Administrator; delivery of a properly executed exercise notice, together with irrevocable instructions to a broker, all in accordance with the regulations of the Federal Reserve Board, to promptly deliver to the Company the amount of sale or loan proceeds necessary to pay the exercise price and any federal, state or local withholding tax obligations that may arise in connection with the exercise; or delivery of a properly

executed exercise notice together with instructions to the Company to withhold from the shares that would otherwise be issued upon exercise that number of shares having a fair market value equal to the option exercise price and withholding tax obligations.
Any unexercised Options that expire or that terminate upon an employee’s ceasing to be employed by the Company, or shares of Restricted Stock that are repurchased by the Company again become available for issuance under the 2007 Plan.
The vesting of outstanding Options under the 2007 Plan will be subject to acceleration upon certain changes in the ownership or control of the Company. The acceleration of the vesting of Options in the event of such changes in control may be seen as an anti-takeover provision and may have the effect of discouraging a merger proposal, a takeover attempt or other efforts to gain control of the Company.
If the Grantee is an officer, director or owner of greater than 5% of our Common Stock at such time, and if we so request and a lead underwriter of any public offering of our Common Stock demands, the Grantee will agree not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of any interest in any of our Common Stock or any securities convertible into or exchangeable or exercisable for or any other rights to purchase or acquire Common Stock (except Common Stock included in such public offering or acquired on the public market after such offering) during the 180-day period following the effective date of a registration statement filed under the Securities Act, or such shorter period of time as the lead underwriter may specify.
Other Terms Applicable to Restricted Stock
We may award Restricted Stock under the 2007 Plan on terms determined by the Plan Administrator at the time of grant. Generally, we issue shares of Restricted Stock to a grantee at a price (the “Purchase Price”) which the Plan Administrator determines at the time of grant. The shares are then classified as “Restricted Shares,” and are subject to our right to repurchase them as set forth on a schedule to the Restricted Stock Agreement entered into between us and the grantee, under which we lose our repurchase rights, and the shares are no longer classified as “Restricted Shares.” The number of shares as to which our repurchase rights lapse generally are determined by the passage of time or the happening of a specified event, such as the attainment of some predetermined performance criteria or a change in corporate ownership or control. The Plan Administrator has discretion in determining the schedule and/or the events that will specify the terms and conditions of the Company’s repurchase rights. Restricted Shares are required to be placed in escrow with us until such time as our repurchase rights lapse. We will generally be entitled to exercise our repurchase rights at any time within 90 days of the grantee’s cessation of “Continuous Service” with the Company by paying an amount equal to the price paid by the grantee for the Restricted Shares.
If the Grantee is an officer, director or owner of greater than 5% of our Common Stock at such time, and if we so request and a lead underwriter of any public offering of our Common Stock demands, the Grantee will agree not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of any interest in any of our Common Stock or any securities convertible into or exchangeable or exercisable for or any other rights to purchase or acquire Common Stock (except Common Stock included in such public offering or acquired on the public market after such offering) during the 180-day period following the effective date of a registration statement filed under the Securities Act, or such shorter period of time as the lead underwriter may specify.
Certain Federal Tax Consequences
Non-Qualified Stock Options
The grant of an NSO under the 2007 Plan does not typically result in any federal income tax consequences to the optionee or to us so long as the exercise price of the option is equal to or exceeds the fair market value of the underlying stock as of the date of grant. Upon exercise of an NSO, the optionee will recognize compensation income (taxed at the rate applicable to ordinary income) on the difference between the option exercise price and the fair market value of the shares on the date of exercise. We are required to pay the employer’s portion of social security, Medicare and other applicable payroll taxes on such income of the optionee, and we are required to withhold and pay over to the relevant tax authorities the federal, state and local income tax withholding and the employee’s portion of such payroll taxes on such income (which the employee is required to pay over to us). We are entitled to an income tax deduction in the amount of the income recognized by the optionee, subject to possible limitations imposed by Section 162(m) of the Code, as well as for the employer’s portion of payroll taxes paid. Any gain or loss on the optionee’s subsequent disposition of the shares will be treated as long-term or short-term capital gain or loss, depending how long the shares are held following the date of exercise (currently for a period of more than one year). We do not receive a tax deduction for any such gain.

Incentive Stock Options
The grant of an ISO within the meaning of Section 422 of the Code under the 2007 Plan does not typically result in any federal income tax consequences to the optionee or to us. An optionee recognizes no federal taxable income upon exercising an ISO (subject to the alternative minimum tax rules discussed below), and we receive no deduction at the time of exercise. The tax consequences of a disposition of stock acquired upon exercise of an ISO depends upon how long the optionee has held the shares. If the optionee does not dispose of the shares within two years after the ISO was granted, nor within one year after the ISO was exercised, the optionee will recognize a long-term capital gain (or loss) equal to the difference between the sale price of the shares and the exercise price. We are not entitled to any deduction under these circumstances.
If the optionee fails to satisfy either of the foregoing holding periods, he or she must recognize ordinary income in the year of the disposition, which is referred to as a "disqualifying disposition". Upon the occurrence of a disqualifying disposition of an ISO, the amount of such ordinary income generally is the lesser of (i) the difference between the amount realized on the disposition and the exercise price, or (ii) the difference between the fair market value of the stock on the exercise date and the exercise price. Any gain in excess of the amount taxed as ordinary income will be treated as a long-term or short-term capital gain, depending on how long the stock was held (currently a period of more than one year). We are entitled to a deduction equal to the amount of ordinary income recognized by the optionee (and the employer’s side of withholding taxes paid) in the year of the disqualifying disposition.
The “spread” under an ISO, i.e., the difference between the fair market value of the shares at exercise and the exercise price, is classified as an item of adjustment in the year of exercise for purposes of the alternative minimum tax calculation of the optionee. The spread is not included in the alternative minimum tax calculation, however, in the event of an early disposition described in the immediately preceding paragraph if the exercise of the ISO and the disposition of the shares acquired upon exercise occur within the same taxable year of the optionee.
Restricted Stock
A participant who is granted restricted stock generally will not recognize income upon the grant unless the participant makes an 83(b) election (discussed in the paragraph immediately below). Rather, such participant will recognize compensation income (taxed at the rate applicable to ordinary income) on the difference between the amount paid (if any) and the fair market value of the shares on the date that the restrictions with respect to the restricted stock lapse (i.e. in the year of vesting). We are required to pay the employer’s portion of social security, Medicare and other applicable payroll taxes on this income, and are required to pay over to the relevant tax authorities the federal, state and local income tax withholding and the employee’s portion of such payroll taxes on this income (which the employee is required to pay over to us). We are entitled to an income tax deduction in the amount of the income recognized by the participant, subject to possible limitations imposed by Section 162(m) of the Code, as well as the employer’s portion of withholding taxes paid. Any gain or loss on the participant’s subsequent disposition of the shares will be treated as long-term or short-term capital gain or loss, depending on how long the shares are held following the date of vesting (currently a period of more than one year). We do not receive a tax deduction for any such gain.
Recipients of restricted stock may make an election under Section 83(b) of the Code to recognize as ordinary compensation income in the year that such restricted stock is granted an amount equal to the difference between the amount paid for such stock and the fair market value on the date of the issuance of the stock. If an 83(b) election is made by the participant, we are entitled to our income tax deduction in the amount of the income recognized by the participant at the time of issuance of the restricted stock (as opposed to later when the shares vest), subject to possible limitations imposed by Section 162(m) of the Code, as well as the employer's portion of taxes paid. If such an election is made, the recipient recognizes no further amounts of compensation income upon vesting and any gain or loss on subsequent disposition will be long-term or short-term capital gain to the participant, depending on how long the shares are held following the date of grant (currently a period of more than one year). An election under Section 83(b) must be made within 30 days from the time the restricted stock is issued.

Performance Share Units
A participant who is granted PSU's generally will not recognize income upon the grant nor upon the vesting of the PSU's, but rather upon the settlement of the PSU's, so long as the award is exempt from or complies with Section 409A of the Code, which typically requires that the PSU's are settled within 2.5 months following the taxable year in which the PSU's vest (i.e., the “short-term deferral” exemption of 409A). We are required to pay the employer’s portion of social security, Medicare and other applicable payroll taxes on this income, and are required to pay over to the relevant tax authorities the federal, state and local income tax withholding and the employee’s portion of such payroll taxes on this income (which the employee is required to pay over to us). We are entitled to an income tax deduction in the amount of the income recognized by the participant, subject to possible limitations imposed by Section 162(m) of the Code, as well as the employer’s portion of withholding taxes paid. For PSU's that are settled in shares of stock, any gain or loss on the participant’s subsequent disposition of the shares will be treated as long-term or short-term capital gain or loss, depending on how long the shares are held following the date of settlement (currently a period of more than one year).
Code Section 162(m)
Subject to the approval by the stockholders of Amendment No. 3 and Amendment No. 4, the Company will be entitled to a deduction equal to the amount of awards or other compensation that qualifies as performance-based compensation” in accordance with Section 162(m) of the Code. However, if the proposals are not approved by stockholders and the Compensation Committee implements alternative methods of paying bonuses in lieu of compensation intended to be “Performance-Based Compensation” under the 2007 Plan, the future deductibility by the Company of any such bonuses may be limited by the $1 million cap on deductibility of compensation under Section 162(m) of the Code.
The foregoing is only a summary of the current effect of federal income taxation upon the grantee and us with respect to the grant and exercise of stock options, shares granted or purchased and other awards or compensation under the 2007 Plan. You should refer to the applicable provisions of the Code. In addition, the summary does not discuss the tax consequences of a grantee’s death or the income tax laws of any municipality, state or foreign country to which the grantee may be subject.
New Plan Benefits
Future awards under the 2007 Plan to our non-employee directors, executive officers and employees are made at the discretion of the Compensation Committee or, with respect to awards not subject to Section 162(m), a committee consisting of Mr. Sampson and Mr. Simonton, subject to certain limitations. At this time, therefore, the compensation that may be received by our executive officers and other employees if our stockholders approve Amendment No. 3 and Amendment No. 4 to the 2007 Plan cannot be determined, and we have not included a table reflecting such benefits and awards.
Board Recommendation
OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE PROPOSAL TO APPROVE AMENDMENT NO. 3, IN ACCORDANCE WITH SECTION 162(m) OF THE CODE, AND AMENDMENT NO. 4 TO THE 2007 PLAN.Our Board recommends that you vote "FOR" all of the persons nominated above, being Carol Eicher, Gilbert Li, J. Taylor Simonton and L. Spencer Wells.

CORPORATE GOVERNANCE
Directors of the Company
The following table sets forth certain information about our directorsEffective as of April 9, 2021, the dateBoard reduced the size of this proxy statement:
the board from seven members to five members. Our Board is currently comprised of four members – Carol Eicher, Gilbert Li, J. Taylor Simonton, and L. Spencer Wells – and these same four directors are nominated for re-election at the Annual Meeting. Brian Leen and R. Carter Pate were directors for a period during 2021, but Mr. Leen resigned from the Board effective April 8, 2021, and R. Carter Pate chose not to stand for re-election to the Board at the 2021 annual meeting. Although the fixed size of our board of directors is five, we have nominated only four directors and have left one vacancy due to the ongoing strategic review process, cost containment strategies and current complexities of the Company. Proxies cannot be voted for a greater number of persons than the number of nominees named.

Board Leadership Structure and Role in Risk Oversight
We have a policy of keeping the roles of Chief Executive Officer and Chair of the Board separate, and the roles are currently filled by two different individuals. We believe this arrangement is appropriate as it recognizes the distinction between the role played by the Chief Executive Officer, whose position is more heavily oriented towards day-to-day management, while the Chair, as an independent director, oversees the Board and is also able to participate in and chair executive sessions of the Board.
Our Board is responsible for establishing broad corporate policies and monitoring the overall performance of the Company. However, in accordance with corporate legal principles, the Board is not involved in day-to-day operating matters. Members of the Board are kept informed of the Company's business by participating in Board and committee meetings, by reviewing analysis and reports sent to them weekly and monthly, and through discussions with the CEO and other officers.
The Board has served as a director of Key Energy Services (NYSE: KEG), an oilfield services company based in Houston, Texas, since 1996. Prior to his appointmentdesignated the Audit Committee oversee risk management, and the Audit Committee periodically reports to the Board of Key Energy Services, he wasregarding briefings provided by management and advisors, as well as its own analysis and conclusions regarding the non-executive Chairmanadequacy of the Company's risk management processes. In addition to this compliance program, the Board encourages management to promote, and management is committed to promoting, a corporate culture that incorporates risk management into the Company's strategy and day-to-day business operations.

Board Leadership Structure and Role in Risk Oversight
We have a policy of keeping the roles of Chief Executive Officer and ChairmanChair of the Board separate, and the roles are currently filled by two different individuals.

Our Board is responsible for establishing broad corporate policies and monitoring the overall performance of the Company. However, in accordance with corporate legal principles, the Board is not involved in day-to-day operating matters. Members of the Board are kept informed of the Company's business by participating in Board and committee meetings, by reviewing analysis and reports sent to them weekly and monthly, and through discussions with the CEO and other officers.








The Board has designated the Audit Committee to take the lead in overseeingoversee risk management, and the Audit Committee periodically reports to the Board regarding briefings provided by management and advisors, as well as the Committee’sits own analysis and conclusions regarding the adequacy of the Company’sCompany's risk management processes. In addition to this compliance program, the Board encourages management to promote, and management is committed to promoting, a corporate culture that incorporates risk management into the Company’sCompany's strategy and day-to-day business operations. The Board and management continually work together to assess and analyze our most likely areas of risk.

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 committed to providing the information necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe the 2021 executive compensation program for our named executive officers.
The Company's named executive officers ("NEOs") for 2021 were:

(1)Because the Short-Term Incentive Plan (the "STIP") has mandatory performance measures that must be achieved before there is any payout to NEOs, amounts paid under the STIP are shown in the Non-Equity Incentive Plan Compensation column of the table, rather than the Bonus column. Amounts earned in 2020 represent bonuses paid to certain executives relating to the completion of a significant customer contract.
(2)The amounts in this column represent the aggregate grant date fair values of restricted stock awards ("RSAs") and performance share units ("PSUs") computed in accordance with FASB ASC Topic 718. These grant date fair values have been determined based on the assumptions and methodologies discussed in Note 16 of the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021. PSU awards are subject to market-based performance conditions relating to the relative placement of the Company’s total stockholder return ("TSR") for the three-year performance period based on the relative performance of the Company’s TSR performance compared to the respective TSRs of a specified group of peer companies. The table below presents the PSU awards granted for the fiscal year ended December 31, 2021 based on an earned percentage of 100% (grant date fair value disclosed above) and an earned percentage of 200%, which is the highest level of performance conditions that can be achieved.

Narrative Disclosure to Summary Compensation Table
Overview of Executive Compensation Program
Our Compensation Committee is charged with establishing the Company’s philosophy for executive compensation and the 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;compensation other than for himself; however, authority to approve compensation, performance goals and objectives for all executivesNEOs is vested in the Compensation Committee.

Our Compensation Committee has the sole authority to engage and compensate a compensation adviser and in November 2012 determined it was in the best interest of the Company to engage a compensation adviser to assist with the design and implementation of compensation arrangements starting in 2013. In November 2012, our Compensation Committee completed a competitive bidding process and selected Longnecker & Associates (“Longnecker”). Based on disclosures made by Longnecker, the Compensation Committee determined that Longnecker meets the independence criteria of Rule 10C-1 of the Securities Exchange Act of 1934, as amended. Longnecker does not provide any other services to the Company.

In 2013, 2014 and 2015, Longnecker advised the Company on:
selection of a peer group for purposes of analyzing and comparing executive compensation data and benchmarking Company performance;
executive officer base salaries and incentive compensation for 2013, 2014 and 2015;
development of STIP (defined below) metrics for 2013, 2014 and 2015;
termination of the RC Plan (defined below);
replacement of the RC Plan with the LTIP (defined below) and a profit sharing incentive plan for our employees; and
the compensation aspects of employment agreement terms for our executive officers, as described below.

Overview - Executive compensation philosophy

Our philosophy for executive compensation is set forth in a document entitled “Executive"Executive Compensation Philosophy and Objectives”Objectives" (the “EC Philosophy”"EC Philosophy") adopted by the Compensation Committee on January 2, 2014 which replaced our Amended and Restated Advanced Emissions Solutions, Inc. Executivereviewed annually by the Compensation Plan (the “EC Plan”).Committee to ensure the EC Philosophy remains appropriate. The EC Philosophy 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 ourthe Company’s vision, mission, strategy, and values to generate profitability and sustained growth in the long-term best interests of our stockholders.stockholders;
▪Aligns executive compensation with measures of performance tied to the strategic and operational performance of the business and stockholder returns.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 ofto the Company, taking

into consideration each executive’s qualifications, level of responsibility and contribution to the Company’s long term performance.long-term performance;
▪Encourages competency-building by linking career development, performance management and compensation rewards.rewards;
▪Attracts and retains the best executive talent and a highly qualified diverse workforce within a non-discriminatory, merit-based compensation program.program; and
Utilizes▪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.
Incentive cash bonuses and long term equity incentive awards consistent with the EC Philosophy are made under our 2007 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.
22

Because of these factors, we believe that our compensation policies and practices, both for our employees generally and for our executive officers, do not create risks that are reasonably likely to have a material adverse effect on the Company.

Say-on-Pay
The Company provides its stockholders with the opportunity to cast an advisory vote on annual executive compensation (a “say-on-pay proposal”"say-on-pay proposal"). AAt the Company’s annual meeting of stockholders in 2021, approximately 97% of the votes cast on the say-on-pay proposal will generally be put forth annually; however, becausewere in favor of the Company did not hold an Annual Meeting of Stockholdersproposal, which the Compensation Committee reviewed in 2014 or 2015, there was no say-on-pay proposal regarding theassessing executive compensation for each of the fiscal years endedyear ending December 31, 2013 and 2014 pursuant to Rule 14a-21 under the Securities Exchange Act of 1934, as amended.2021.

("LB & Co."), in 2020 to provide a market analysis of Named Executive Officersthe 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. was determined to have no conflicts of interest and only provided services with respect to director and executive compensation.

The Company's namedCompensation Committee reviewed these peer companies and approved their use for comparison to the Company. For compensation related to 2021, the Compensation Committee reviewed this market compensation analysis and peer group compensation data to ensure executive officers ("NEOs") for 2015 were:

Base SalariesSalary
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. In consultation with Longnecker,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 theiran 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 utilizes incentive compensation in the form of stock and equity awards to motivate executives and align executive and stockholder interests. Incentive amounts are set based on job position and market practices. Incentives paid in cash are subject to payroll taxes and other customary withholdings. In addition to awards under the Company’s Short-Term Incentive Plan (“STIP”) and Long-Term Incentive Plan (“LTIP”), we generally grant restricted stock awards to new executive officers.

The STIP is designed to motivate executives to achieve critical short-term goals, typically within a twelve monthtwelve-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
23

determined by the Compensation Committee. For 2013, STIP awards were made under the EC Plan. On February 12, 2014, the Compensation Committee approved Amendment No. 2 to the Company’s 2007 Plan, which amended the 2007 Plan to make non-material changes to specifically allow for cash awards, such as under the STIP, and establish certain procedures for such cash awards. STIP awards for 2014 and 2015 were made under the 2007 Plan. The Compensation Committee adopted the Executive Short TermShort-Term Incentive Plan (“ESTIP”("ESTIP") onin September 9, 2015 to further establish terms and conditions for cash awards made under the STIP, and theSTIP. The Compensation Committee expects to make futuremakes STIP awards under the 20072017 Omnibus Incentive Plan (the "2017 Plan") and the ESTIP.

On April 9, 2021, the Compensation Committee established cash bonus targets equal to 75% of base salary for Mr. Marken and 50% of base salary for each of Ms. Fields and Mr. Wong. The performance goals on which the awards are based on Company and individual performance goals approved by the Committee. Company performance goals include the attainment of performance-based metrics reviewed and approved by the Compensation Committee. Budgeted Revenue and Adjusted EBITDA, as defined by the Compensation Committee, were the specific metrics used in assessing cash bonus targets. Both performance metrics were exceeded during the year.
In 2022, the Compensation Committee approved 2021 performance bonuses for Messrs. Marken and Wong and Ms. Fields at 158%, 158% and 158%, respectively, of the target based on Company and individual performance goals.
Long-Term Incentive Compensation
The LTIPLong-Term Incentive Plan ("LTIP") is designed to align executives’ interests with those of the Company’s stockholders.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 RSA's, PSU's, Stock OptionsRSAs or SAR's.PSUs. Equity awards may vest

immediately, over time based on continuous service, or over time based on achievement of certain performance goals, as determinedmeasures 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 20072017 Plan. Generally, equity awards are granted on or about the same day that the Compensation Committee approves such grant. Exercise prices are set based on the closing market price on the grant date.

From time to time 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 such payments were made in 2015, 2014 or 2013 other than the RC Bonus and equity awards to Mr. Sampson described below.

The stock portions of the 2015, 2014 and 2013 incentive awards are shown below in the Summary Compensation table under the “Stock Awards” column. The cash portions of the 2015, 2014 and 2013 incentive awards are shown below in the Summary Compensation table under the “Non-Equity Incentive Plan Compensation” column.

Company Policies Relating to Executive Compensation Plans
Refined Coal Activities Supplemental Compensation PlanInsider Trading Policy
On April 20, 2010, the Compensation CommitteeOur Insider Trading Policy, which applies to our employees, officers and directors, prohibits hedging of our Board adoptedsecurities and engaging in any other transactions involving ADES-based derivative securities, regardless of whether the Refined Coal Activities Supplemental Compensation Plan, which was amended and restated on November 9, 2011 (the “RC Plan”). The RC Plan provided for the allocationcovered person is in possession of annual incentive cash awards in an amount equal to seven percent of the “Net Contribution Margin” (as defined in the RC Plan) resulting from our “Refined Coal Activities” (as defined in the RC Plan), which at the time were activities of CCS as its financial statements were consolidatedmaterial, non-public information (except with ours priorregard to the restatementvesting of financial statements, as described within the Annual Report on Form 10-K for the fiscal year ended December 31, 2014. The amount of each incentive award was calculated and paid annually following the close of each fiscal year and allocated as follows: three percent of Net Contribution Margin, or 42.85% of the amount of the award, was allocatedsecurities acquired pursuant to our Chief Executive Officer, Dr. Michael Durham,incentive plans), or other transactions involving purchases and four percentsales of Net Contribution Margin,company securities between a covered person and us. The Insider Trading Policy also prohibits all employees, officers and directors from entering into any transaction relating to hedging ADES securities, including zero-cost collars or 57.15% offorward-sale transactions.
Equity Ownership Guidelines
So long as the amount of the award, was allocated to those eligible RC Plan participants selected by the CEO based on their contributions to our Refined Coal Activities during the prior fiscal year. The RC Plan was amended in November 2011 to clarify the “Revenue”stock ownership guidelines are met, executives may sell unrestricted stock and “Expense” components that were used to calculate the Net Contribution Margin

may exercise vested stock options and to include “Clawback Rights” pursuant to which we would be entitled to a return of amounts paid out under the RC Plan if we were required to refund any of the cash reflected in Revenue upon which an award was made. In February 2012, the Compensation Committee limited the “Clawback Rights” to apply only to our executive officers, set a minimum threshold for their application and provided that any clawback would be an offset against any future incentive compensation. These changes were made based on concerns as to the possible negative impact any exercise of such rights may have on employee morale, the costs and difficulty of administering any clawback and the unlikelihood that any such clawback right may arise.

Pursuant to the terms of the RC Plan, seven percent of the Net Contribution Margin, as defined in the RC Plan, received from the Company’s Refined Coal Activities funded the annual RC Plan incentive pool.  In 2010 and 2011, the Company awarded $430,000 and $283,000, respectively. In March 2013, the Compensation Committee approved the calculation of an award amount of approximately $223,000 for the Company's executive officers under the RC Plan based on Refined Coal Activities in 2011 due to cash distributions from CCS in 2013.

During 2012, the Compensation Committee discussed various changes to the RC Plan based on input from senior management and in March 2013 terminated the RC Plan in favor of the LTIP. In lieu of an award under the RC Plan with respect to Refined Coal Activities in 2012, on March 20, 2013, the Compensation Committee approved a discretionary bonus in the aggregate amount of approximately $723,000 based on the calculations that would have been made pursuant to certain of the changes discussed during 2012, including inclusion of an award based on tax credits generated by CCS during 2012 due to Refined Coal Activities.

(7) Prior to Mr. Gabbard's appointment to Chief Financial Officer in June 2015, he received compensation as a director of the Company through May 31, 2015, including; 1) prorated annual retainer of $19,792 and 2) prorated committee fees of $4,167.
(8) The Company paid expenses in conjunction with Mr. Lagarenne's relocation to Colorado and provided an additional gross-up amount to cover the tax withholding obligation in the amount of $80,213.
Equity Compensation Plans (Stock Incentive Plans)
Pursuant to the Agreement and Plan of Merger dated as of March 25, 2013, the Company assumed the equity incentive plans of ADA and all awards made under such plans. On August 6, 2013, the Company authorized the General Amendment of Company Plans, which amended those plans listed below to refer to the Company and the Company’s common stock, par value $0.001, and change the governing law from Colorado to Delaware. Any amount of shares referenced with regard to the equity incentive plans identified below reflects the 2:1 stock split of the Company’s Common Stock on March 14, 2014 as required by the plan documents.
2005 Directors’ Compensation Plan
During 2005 we adopted the 2005 Directors’ Compensation Plan (the “2005 Plan”), which authorized the issuance of shares of common stock and the grant of options to purchase shares of our common stock to non-management directors. The 2005 Plan was approved by our stockholders at the 2005 Annual Meeting. The 2005 Plan is intended to advance our interests by providing eligible non-management directors an opportunity to acquire or increase an equity interest in the Company, create an increased incentive to expend maximum effort for our growth and success and encourage such eligible individuals to continue to service

the Company. The 2005 Plan provides a portion of the annual compensation to our non-management directors in the form of awards of shares of common stock and vesting of options to purchase common stock for services performed for the Company. Under the 2005 Plan, the award of stock is limited to 2,000 shares per individual per year, and the grant of options is limited to 10,000 per individual in total. The aggregate number of shares of common stock reserved for issuance under the 2005 Plan totals 180,000 shares (100,000 in the form of stock awards and 80,000 in the form of options). The exercise price is the market price on the date of grant, the shares of common stock underlying the option will vest at a rate of no more than 3,334 shares per annual period per individual, and any unvested shares of Stock that are outstanding at the date the individual is no longer a director are forfeited. Shares may be issued and options may be granted under the 2005 Plan only to non-management directors of the Company or its subsidiaries. The 2005 Plan was administered by the Compensation Committee of the Board.

The 2005 Plan terminated ten years after the date of its adoption, which was March 17, 2015. During 2014, two 5-year options, to purchase 10,000 shares each, were awarded and as of December 31, 2015, four 10,000 five-year options remain outstanding.
2007 Plan
During 2007, we adopted the 2007 Equity Incentive Plan, which replaced the 2003 Plan. The plan was amended and restated as of August 31, 2010 to make non-material changes to assure compliance with Section 409A of the Internal Revenue Code and to increase the non-management director annual grant limit to 30,000 shares of common stock from 20,000 shares (the share amounts reflect the 2:1 stock split of the Company’s Common Stock on March 14, 2014). The 2007 Plan was amended pursuant to Amendment No. 1 to the plan, approved by the Board on January 25, 2011, re-approved by the Board on February 24, 2012 and approved by our stockholders on July 19, 2012, to increase the amount of authorized and issuable shares to 2,600,000 shares, and to also increase the limits of shares that may be granted to individuals and directors to 100,000 shares and 50,000 shares respectively.

The 2007 Plan was amended pursuant to Amendment No. 2 to the plan, approved by our Compensation Committee on February 12, 2014, to make non-material changes to the 2007 Plan to specifically allow for cash awards, such as under the Short Term Incentive Plan, and establish certain procedures for such cash awards.

Amendment No. 3 to the 2007 Plan was approved by the Compensation Committee on February 12, 2014 and the Board on February 13, 2014 and is pending stockholder approval. Amendment No. 3 amends the 2007 Plan to add performance criteria, which is required to qualify awards under the 2007 Plan as Performance-Based Compensation under Section 162(m) of the IRC. The 2007 Plan initially authorized the issuance to employees, directors and consultants of up to 2,600,000 shares of common stock, subject to automatic increases pursuant to the 2007 Plan’s evergreen provision, either as restricted stock, grants to underlie options to purchase shares of our common stock or other benefits under the plan (with a maximum number of shares of 3,600,000 authorized). Under the 2007 Plan, the award of stock is currently limited to not more than 100,000 shares per individual per year with a maximum of 50,000 shares grantable in any year to non-management Directors as established in Amendment No. 1 discussed above.

Amendment No. 4 to the 2007 Plan, which was approved by the Board on June 5, 2015 and is pending stockholder approval, proposed to increase the individual limit to 400,000 shares per individual per year(the limit for non-management directors will remain at 50,000 shares). This increase is to effectuate the Board's decision to compensate the CEO as discussed in the Additional Executive Compensation Plans section above. See Proposal No. 4 included in this Proxy Statement for more information about Amendment Nos. 3 and 4.

In general, all options granted under the 2007 Plan will expire ten years from the date of grant unless otherwise specified by the Board. The exercise price for options granted under the 2007 Plan will be the market price on the date of grant, and the shares of common stock underlying the option, RSA's, PSU's and SAR's will vest on the passage of specified times following the date of grant, the occurrence of one of more events, the satisfaction of performance criteria or other conditions specified by the Board. The 2007 Plan is administered by the Compensation Committee. During 2015, 56,250 Stock Options, 127,943 RSA's and 138,436 PSU's were granted. As of December 31, 2015, 706,509 shares have been reserved but not yet issued under the 2007 Plan.
401(k) Plan
Our 401(k) Plan allows the Company to issue shares of common stock to employees to satisfy its obligation to match employee contributions under the terms of the 401(k) Plan in lieu of matching contributions in cash. The Company reserved 600,000 shares of its common stock for this purpose. The value of common stock issued as matching contributions under the 401(k) Plan is determined based on the per share market value of our common stock on the date of issuance. During 2015, no shares were issued to satisfy the Company's obligation to match employee contributions. As of December 31, 2015, 229,618 shares of common stock are available for issuance under the 401(k) Plan.

2010 Non-Management Compensation and Incentive Plan
During 2010, our Board adopted the 2010 Non-Management Compensation and Incentive Plan, which authorized the issuance of shares of common stock, restricted stock or other rights or benefits under the plan to non-management employees and consultants. Our Board approved the Amended and Restated 2010 Non-Management Compensation and Incentive Plan in March 2011, readopted such plan in February 2012, and our stockholders approved the plan at the 2012 Annual Meeting. The purposes of the Amended and Restated 2010 Non-Management Compensation and Incentive Plan, as amended (the "2010 Plan") are to attract and retain the best available personnel, to provide additional incentives to non-management employees and consultants and to promote the success of the Company’s business. The number of shares authorized for issuance under the 2010 Plan is limited to 600,000.

The 2010 Plan will terminate ten years after the date of its adoption, if not earlier terminated by the Board. It may be amended, modified or terminated at any time if and when it is advisable in the absolute discretion of the Board, although certain amendments are subject to approval of regulatory bodies and our stockholders. The Compensation Committee is the Plan Administrator of the 2010 Plan, as is the Stock Committee with limited authority. During 2015, no RSA's were granted from the 2010 Plan. As of December 31, 2015, 565,452 shares of common stock are available for issuance under the 2010 Plan.

(1) The grant date fair value of a PSU is calculated using a Monte Carlo simulation model, and the aggregate grant date fair value represented in this column for PSU's is calculated based upon the target number of PSU's granted.
(2) This amount represents RSA's granted under our 2007 Plan. The RSA's have no threshold or maximum amounts. The RSA's vest one-third on January 1, 2016, one-third on January 1, 2017, and one-third on January 1, 2018. Prior to vesting, the RSA's are subject to transfer restrictions and may be forfeited upon termination of employment. The RSA's are eligible for dividends. Holders of RSA's have no rights as stockholders of common stock, except for dividends, until such time as the RSA's are settled for shares of common stock as of the vesting date. 
(3) These amounts represent PSU's granted under our 2007 Plan. PSU's represent the right to receive, upon settlement of the PSU's after the completion of a three-year performance period ending December 31, 2017 a number of shares of our common stock that may be from 0% to 200% of the number of PSU's granted on the award date, depending on the extent to which our performance criteria have been achieved and the extent to which the PSU's have vested. The performance criteria for the PSU's are based on a combination of our TSR for the performance periods and the relative measure of our TSR performance compared to the specified group of peer companies and Russell 3000 Index. The PSU's will vest on January 2, 2018. The target amount represents the number of shares of common stock earned

and to be issued upon settlement of the PSU's, assuming we achieve the target performance level established by our Compensation Committee. The threshold amount represents the number of shares of common stock earned and to be issued upon settlement of the PSU's, assuming we achieve the threshold performance level. The maximum amount represents the number of PSU's issued and the shares of common stock earned and to be issued upon settlement of PSU's, assuming we achieve the maximum performance level. 
(4) This amount represents stock options and SAR's granted under our 2007 Plan. These awards have no threshold or maximum amounts. Of these awards, 56,250 stock options were immediately vested on grant date. The other 243,750 stock options were granted contingent upon approval of Amendment No. 4 to the 2007 Plan by the Company's stockholders ("Plan Approval"). If Plan Approval is not obtained on or before June 5, 2017, the Mr. Sampson would become entitled to exercise, in exchange for the stock options, 243,750 SAR's that are subject to the same vesting schedule as the stock options and settled in cash based upon the appreciation, if any, of the Company's common stock on the day of exercise versus the day of grant. Of these 243,750 stock options or SAR's, 43,750 immediately vested on grant date, 100,000 will vest on December 5, 2016, and 100,000 will vest on June 5, 2018, or earlier based on the achievement of certain pre-established performance goals, subject to Mr. Sampson's continuous service.
(5) On December 11, 2015, the Compensation Committee amended Mr. Sampson's previous cash bonus award from $79,158 to $379,158 in recognition of Mr. Sampson's extensive work and for retention purposes, subject to the achievement of certain performance criteria.
(6) This amount represents RSA's granted under our 2007 Plan. The RSA's have no threshold or maximum amounts. The RSA's vested upon the filing of Quarterly Reports on Form 10-Q for the quarters ended March 31, June 30, and September 30, 2015 and the Annual Report on Form 10-K for the fiscal year ended December 31, 2015.
(7) Additional RSA's and PSU's granted under our 2007 Plan in recognition of Ms. Sjostrom's promotion to Chief Product Officer. The vesting schedules for these RSA's and PSU's follow the same schedules described above in footnotes (2) and (3) above, respectively.

Employment Agreements
We have executed employment agreements with all of our executive officers. The agreements with all of our executive officers generally contain the following provisions:
1.Description of position, duties, authority, compensation, benefits and obligation of the employee to devote full time to the fulfillment of his/her obligations under the agreement.
2.Obligations to disclose and Company ownership of inventions and/or confidential subject matter that is developed by such employee, and acknowledgment that the Company shall retain ownership of inventions and confidential subject matter, which obligations survive for two years after termination of employment.
3.Assignment of inventions, obligations regarding inventions and confirmation of no Company obligation to commercialize inventions, all of which survive after termination of employment.
4.Acknowledgment that copyright works are “works for hire” and obligation of employee to maintain written records of all inventions and confidential subject matter.

5.Restrictive obligations relating to confidential subject matter, which survive after termination of employment.
6.Acknowledgment and agreement regarding no conflicting obligations and obligations upon termination of employment.
Prior to 2014, our executive officers were not subject to any restrictive covenants, such as provisions regarding notice, severance, change in control and covenants regarding non-competition, non-solicitation and non-divergence (“Restrictive Covenants”). In consultation with the Company’s compensation adviser and legal counsel, the Compensation Committee determined it was in the best interests of the Company that the Company’s executive officers be subject to Restrictive Covenants. The Compensation Committee discussed with the Company’s independent directors and approved forms of amendments to the employment agreements of our executive officers at that time, consisting of our President and Chief Executive Officer; Chief Technology Officer (now Chief Product Officer); General Counsel; and Vice President of Investor Relations (now Vice President of Strategic Initiatives and Investor Relations), which were entered into between the Company and each such executive on August 26, 2014 and between the Company and the Chief Accounting Officer and Executive Vice President on September 19, 2014 (together, the “2014 Amendments”). Our then Chief Financial Officer, Mr. McKinnies, and then Chief Operating Officer, Ms. Bustard, retired in 2014 and entered into retirement agreements with the Company in lieu of any amendment to their employment agreements (see description of their respective retirement agreements below).
The 2014 Amendments contain terms that the Compensation Committee believes were necessary to induce the current executive officers to agree to Restrictive Covenants. The 2014 Amendments also serve as incentive for future performance and services of our executive officers. The terms of the 2014 Amendments are different from, and potentially less favorable to the Company than the terms contained in the form Executive Rider approved by the Compensation Committee in August 2014 for future executive officers, but the Compensation Committee determined that such terms were outweighed by the value to the Company of obtaining the Restrictive Covenants from our executive officers at that time for a period of time elected in the sole discretion of the Company. The 2014 Amendments address the parties’ respective obligations upon the termination of the respective executive’s employment under various circumstances, including Cause, Good Reason, or Change in Control, as those terms are defined in the 2014 Amendments, disability or death.
The Compensation Committee determined that the terms of the 2014 Amendments were reasonable given the circumstances. For example, severance compensation owed pursuant to the 2014 Amendments is subject to double triggers (e.g. a Change in Control and election by the Company to enforce the Restrictive Covenants for a specified period of time elected by the Company).
The 2014 Amendments include the following provisions:
1.The Company or the executive is required to give notice of termination of his or her employment: (i) if an executive’s employment is terminated for Cause, termination is effective immediately upon notice and (ii) for any other termination, termination is effective 45 days after notice although the Company may terminate an executive’s employment at any time by written notice after receiving notice of resignation from an executive for a reason other than Good Reason.
2.Upon termination of any executive’s employment, we must pay the executive his or her base salary and other accrued benefits through the termination date. We must also pay additional amounts depending upon whether the termination was for or without Cause or Good Reason, or whether the termination was for or without Cause or Good Reason following a Change in Control, as set forth below.
a.Termination without Cause or with Good Reason. If we terminate the executive’s employment without Cause or if the executive resigns for Good Reason, the executive will be subject to a 12-month prohibition on activities that compete with our business (a “Non-Compete”) and we will pay the executive 12 months base salary payable on the established payroll dates (bi-weekly), the pro-rated portion of short term incentive cash bonuses that would have been earned if the executive had been employed for the full year payable in a lump sum when such payment is paid to other employees or executives under the applicable short term incentive program, based upon actual performance, vesting of executive’s unvested restricted stock and the value of executive’s unvested performance share units determined by calculating total stockholder returns against the common stock returns of the established Company peer group in accordance with the long term incentive plan using the Termination Date as the ending date of the applicable performance period and if greater than zero, such calculated value shall be paid to the Executive, in Company Stock, within thirty days of the Termination Date. Additionally, at the executive’s request, the Company shall pay up to 12 months of medical insurance coverage. If such termination is within 12 months following a change of control, or if we elect to enforce a 24 month Non-Compete, we must pay 24 months base salary and two times the pro-rated portion of short term incentive cash bonuses that would have been earned by the executive. The unvested equity vests and is paid as set forth above.

b.Termination for Cause or without Good Reason. If we terminate an executive’s employment for Cause or the executive resigns without Good Reason, and if we elect to enforce either a 12 month or a 24 month Non-Compete, we must pay the same amounts as described above for Termination without Cause or with Good Reason. If the Company does not elect to enforce a Non-Compete, no severance payments shall be paid to executive.
c.If an executive resigns for a reason other than Good Reason within three months prior to or six months after closing of a Change in Control, we may elect to enforce a twelve month Non-Compete by paying the same base salary and prorated portion of short term incentive compensation as set forth above for other 12-month Non-Compete elections. In this circumstance, no unvested equity will vest or be paid.
d.If an executive’s employment is terminated due to death or permanent disability, we must pay any short term incentive cash bonuses that would have been earned by executive if he or she had been employed for the full year as follows: 50% of the target amount if the termination occurs within the first half of the year or 100% of the target amount if the termination occurs within the second half of the year. In addition, any unvested restricted shares held by such executive would vest, and we must pay executive for the value of any unvested performance share units held by the executive as set forth above.
3.The agreement of the Chief Executive Officer at the time of the 2014 Amendments, Michael Durham, differed from the other executives in that he was entitled to be paid two times the target amount of the short term incentive cash bonus if his employment were terminated without Cause or he resigned for Good Reason following a Change in Control, and would be paid the target amount if he resigned for a reason other than a Good Reason within three months prior or six months after closing of a Change in Control. In addition, if Dr. Durham had resigned under those circumstances, any unvested restricted stock held by him would vest, and we would have been required to pay him for the value of his unvested performance share units. On April 30, 2015, Dr. Durham retired from the Company and entered into a Severance Agreement (the “Severance Agreement”), which is discussed below.
4.The Amendment for Ms. Smith differed in that if she were terminated or she resigned from her position as CAO and her authority, duties and responsibilities were changed such that she were assigned duties at either the Company or ADA in a Vice President or above role with at least the same Base Salary, such termination, resignation, reduction in Total Compensation and diminution in authority, duties or responsibilities would not be deemed to be Good Reason and would not be considered a termination of her employment. If Ms. Smith were to become an executive of ADA, the Amendment would automatically be assigned to and assumed by ADA. The Company eliminated the CAO position and entered into a Waiver and Release Agreement with Ms. Smith effective March 2, 2015, which further amended certain provisions of Ms. Smith’s employment agreement, as amended.
5.The 2014 Amendments also contain requirements that the executives comply with the terms of the Non-Competes, and standard prohibitions on soliciting employees and diverting Company business. If the Executive should breach any of the provisions of this Amendment with regard to the confidentiality of information, the Executive’s rights to any further consideration or payments under the Amendment will terminate as of the date of any such breach. The Amendment provides a cutback permitting the Company to adjust compensation payable to an executive that is subject to certain excise taxes imposed under Section 4999 of the Internal Revenue Code of 1986, as amended.
6.For purposes of the 2014 Amendments:
a.“Cause” means conduct by the Executive that has been proven to include one or more of the following as finally determined by a court of law, government agency, or final settlement: (i) dishonesty, willful misconduct, or material breach of the Company’s Code of Conduct, including the Insider Trading Policy, or (ii) felony conviction of a crime involving dishonesty, breach of trust or physical harm to any Person, or (iii) a breach of any fiduciary duty and such conduct has had or is reasonably likely to have a material detrimental effect on the Company or a Related Person.
b.“Change in Control” means a change in our ownership or control effected by a direct or indirect acquisition of more than 50% of our total combined voting power, replacement of our directors by directors whose appointment or election is not endorsed by our directors serving immediately prior to such replacement, or a change in the ownership of a substantial portion of our assets.
c.“Good Reason” means a material reduction in the executive’s compensation, a material diminution in the executive’s authority, duties or responsibilities, or a relocation of more than 50 miles, subject to our right to cure.

The foregoing description of the 2014 Amendments does not purport to be complete and is qualified in its entirety by reference to the 2014 Amendments signed by Ms. Amrhein, Dr. Durham, Mr. Mattison and Ms. Sjostrom, a form of which is attached as Exhibit 10.67 of the Company’s Current Report on Form 8-K filed on September 2, 2014, and signed by Mr. Lagarenne and Ms. Smith, a form of which is attached as Exhibit 10.69 of the Company’s Current Report on Form 8-K filed on September 22, 2014, both of which are incorporated herein by reference.
In addition, beginning in 2014, each new executive officer of the Company executed a rider to their employment agreements (“Executive Rider”), which, among other things, added certain Restrictive Covenants to the employment agreement. The Executive Rider, which is applicable to Messrs. Sampson and Gabbard, includes terms in accordance with the following provisions:
1.The Company or the executive is required to give notice of termination of his or her employment: (i) if an executive’s employment is terminated for Cause, termination is effective immediately upon satisfying the Notice requirements and (ii) for any other termination, termination is effective 45 days after notice although the Company may terminate an executive’s employment at any time by written notice after receiving notice of resignation from an executive for a reason other than Good Reason.
2.Upon termination of any executive’s employment, we must pay the executive his or her base salary and other accrued benefits through the termination date or as required by law. We must pay additional amounts depending upon the circumstances for the termination as set forth below:
a.For Cause or Without Good Reasons. If we terminate the executive for cause or the executive resigns without good reason no additional payment is required.
b.
Without Cause or For Good Reasons. If we terminate the executive without cause or the executive resigns for good reason we must pay the executive twelve months base salary payable on established payroll dates (bi-weekly). If termination is within 12 months following a change of control, we must pay: (i) 12 months base salary payable as stated above, (ii) short term incentive cash bonuses based on actual performance, based upon the number of days the executive was employed by the Company in the year of termination payable in a lump sum when such payment is paid to other employees or executives under the applicable short term incentive program, (iii) all unvested restricted stock will vest, and (iv) the value of his or her unvested performance share units, the value of any unvested performance share units shall be determined by calculating total stockholder returns against the common stock returns of the established Company peer group in accordance with the applicable long term incentive plan using the Termination Date as the ending date of the applicable performance period. If greater than zero, such calculated value shall be paid to the executive, in Company stock (less shares withheld for tax purpose in accordance with the applicable equity plan document) within 30 days of the Termination Date. Additionally, at the executive’s request we must provide medical insurance coverage under COBRA or medical insurance premiums for the shorter of 12 months from the Termination Date or the executive’s eligibility under other employer or medical insurance plans.
c.If an executive’s employment is terminated due to death or permanent disability, we must pay any short term incentive cash bonuses that would have been earned by executive if he or she had been employed for the full year as follows: 50% of the target amount if the termination occurs within the first half of the year or 100% of the target amount if the termination occurs within the second half of the year. In addition, any unvested restricted shares held by such executive would vest, and we must pay executive for the value of any unvested performance share units held by him or her.
3.
The executive must comply such executive’s pre- and post-employment obligations to maintain the confidentiality of information and to assign intellectual property rights to the Company and comply with the Non-Compete, Non-Solicit and Non-Divert requirements of the Executive Rider for 12 months.If the executive should breach any of the provisions of this Amendment with regard to the confidentiality of information, the executive’s rights to any further consideration or payments under the Amendment will terminate as of the date of any such breach.
4.The Amendment provides a cutback provision permitting the Company to adjust compensation payable to an executive that is subject to certain excise taxes imposed under Section 4999 of the Internal Revenue Code of 1986, as amended, a provision enabling the Executive to elect that shares be withheld by the Company for the satisfaction of tax obligations.
5.For purposes of the Executive Rider, (i) “Cause” means with respect to the Executive (i) the failure by Executive to substantially perform the essential functions of Executive’s duties or obligations in a satisfactory manner (other than due to a Death or Disability) or material breach of any written agreement with the Company or a Related Person; (ii) dishonesty, willful misconduct, or material breach of the Company’s Code of Conduct, including the Insider Trading Policy Appendix, or knowing violation of any federal or state securities or tax laws, or any misconduct that is, or is reasonably likely to be, materially injurious to the Company or a Related Person, monetarily or otherwise; (iii) conviction of or plea of guilty or no contest to a crime involving dishonesty, breach of trust or physical harm to any Person; or (iv) a breach of any fiduciary duty that has had or is reasonably likely to

have a material detrimental effect on the Company or a Related Person. “Good Reason” and “Change of Control” have the same meaning as set forth in the 2014 Amendments.

The foregoing description of the Executive Rider does not purport to be complete and is qualified in its entirety by reference to the Executive Rider signed by Mr. Sampson, a form of which is attached as Exhibit 10.66 of the Company’s Current Report on Form 8-K filed on September 2, 2014, which is incorporated herein by reference.
The compensation amounts included in the employment agreements are subject to annual adjustment and the compensation levels for the named executive officers are shown in the tables above.
Retirement of McKinnies and Bustard in 2014

Mark H. McKinnies, former Director, Senior Vice President, Chief Financial Officer, Treasurer and Secretary of the Company, retired from the Company on August 26, 2014. C. Jean Bustard, former Chief Operating Officer of the Company, retired from the Company on December 31, 2014. Pursuant to the agreements described below, Ms. Bustard and Mr. McKinnies received severance payments in 2015.

On September 2, 2014, we announced the retirement and resignation of Mark H. McKinnies as Senior Vice President, Chief Financial Officer, Treasurer, Secretary and director of ADES and of all of his positions at our subsidiaries. Mr. McKinnies entered into a Retirement and Non-Competition Agreement with the Company on August 26, 2014 (the "Retirement and Non-Competition Agreement"). Pursuant to the Retirement and Non-Competition Agreement, Mr. McKinnies received his regular compensation through his retirement date including base salary and accumulated vacation and other benefits. Subject to any finding of Cause (as defined the Retirement and Non-Competition Agreement) against Mr. McKinnies, he has been and will continue to also be paid: (i) severance of up to two years’ base salary payable in equal bi-weekly installments of $13,900 less all applicable deductions over two years, commencing September 12, 2014, for a total amount not to exceed $696,280 and (ii) costs of obtaining replacement medical and dental coverage for eighteen months, paid in bi-weekly installments of $437.50, for a total amount not to exceed $22,750. Mr. McKinnies is also entitled to be paid an amount equal to any 2014 short-term incentive or other cash bonus based on Company performance that would have been earned by him if he had been employed for the full year, payable in a lump sum when such payment is earned, vested and determinable, no later than March 15, 2015. The Company paid Mr. McKinnies $85,432 in April 2015 based upon the Company’s performance against its goal regarding sales of dry sorbent injection systems and activated carbon injection equipment. In accordance with the Compensation Committee’s determination in November 2015 that the two outstanding metrics (earnings and retained ton tax credits and value added revenue) were not met and would not be paid, Mr. McKinnies will not receive any additional amounts under the 2014 STIP. Mr. McKinnies also did not and will not receive any amount under the 2014 STIP for his individual performance goal. Mr. McKinnies’ also holds unvested restricted stock and unvested PSU's that will not vest until the earlier of a determination by the Board of Directors of the Company that the matters relating to the restatements and re-audits of the Company’s prior financial statements, as reflected herein, (“Accounting Matters”) have been resolved without a finding of Cause against Mr. McKinnies or by December 31, 2015 (the “determination date”) if a Cause determination has not been made. If such unvested PSU's should vest, the value shall be determined by calculating total stockholder returns against the common stock returns of the established Company peer group in accordance with the applicable long term incentive plan using December 31, 2015 as the ending date of the applicable performance period. If greater than zero, such calculated value shall be paid to Mr. McKinnies, in Company stock, within the timing required by his agreement.

For purposes of the Retirement and Non-Competition Agreement, “Cause” means (i) willful and wanton misconduct or material breach of the Company’s Code of Conduct, including the Insider Trading Policy, or willful and wanton violation of any federal or state securities or tax laws, or reckless misconduct that is, or is reasonably likely to be, materially injurious to the Company or a Related Person, monetarily or otherwise; (ii) conviction of or plea of guilty or no contest to a crime involving dishonesty, breach of trust or physical harm to any Person; or (iii) intentional breach of fiduciary duty where such conduct had or is reasonably likely to have a material detrimental effect on the Company or a Related Person; or (iv) material breach of the Employment Agreement. In December 2015, the Board made a determination of Cause against Mr. McKinnies. As a result of the determination of Cause, all cash payments to Mr. McKinnies have ceased and the unvested restricted stock and unvested PSU's will not vest and are forfeited pursuant to the terms of the Retirement and Non-Competition Agreement.

The Retirement and Non-Competition Agreement contains a standard release and covenant not to sue, as well as a two-year prohibition on activities that compete with our business (a “Non-Compete”), and non-solicitation and non-diversion covenants consistent with those of the other executives’ agreements described above. However, since the Accounting Matters were resolved with a finding of Cause against Mr. McKinnies, the non-compete requirements ceased on the determination date.


The foregoing description of the Retirement and Non-Competition Agreement does not purport to be complete and is qualified in its entirety by reference to the Retirement and Non-Competition Agreement, a copy of which is attached as Exhibit 10.65 of the Company’s Current Report on Form 8-K filed on September 2, 2014, and is incorporated herein by reference.

On September 19, 2014 we announced the retirement of C. Jean Bustard as Chief Operating Officer effective at the end of December 31, 2014. Ms. Bustard entered into an amended employment agreement with the Company that contains the terms of her retirement and pursuant to which she resigned various positions at the Company’s subsidiaries. Her salary and STI bonus compensation remained unchanged through December 31, 2014. After her retirement and the Company’s receipt of a release of claims from her on the Company’s standard form, Ms. Bustard has been receiving and will continue to receive 52 equal installments of $11,488 less all applicable dedications and withholdings required by law, for a total amount not to exceed $597,400 and received a lump sum of $24,385, which represents the cost of obtaining replacement medical, dental and vision coverage for 18 months paid in January 2015. Ms. Bustard’s Equity Awards (as defined in her agreement) that remained unvested accelerated and became fully vested as of her retirement date. Additionally, Ms. Bustard must comply with her pre- and post-employment obligations to maintain the confidentiality of information and to assign intellectual property rights to the Company and comply with the Non-Compete, Non-Solicit and Non-Divert requirements for 24 months.

The foregoing description of the Amendment to Employment Agreement does not purport to be complete and is qualified in its entirety by reference to the Amendment, a copy of which is attached as Exhibit 10.68 of the Company’s Current Report on Form 8-K filed on September 22, 2014, and is incorporated herein by reference.

Mr. Lagarenne is entitled to the severance compensation as set forth in Section III of the 2014 Amendment in exchange for, among other things, compliance with the Restrictive Covenants, for which the Company elected a 12 month period. The 2014 Agreement is summarized above and a form of it is filed as Exhibit 10.69 to the Company’s Current Report on Form 8-K filed with the SEC on September 22, 2014. By entering into the Lagarenne Agreement, Mr. Lagarenne will receive additional consideration from what he is otherwise entitled to under the 2014 Amendment in exchange for a general release of claims against the Company, other customary terms and delayed vesting of, and receipt of common stock underlying, his PSU’s.

DIRECTOR COMPENSATION
Our Nominating and Governance Committee has responsibility for reviewing the compensation plan for our non-management directors annually and making recommendations to the entire Board for approval. The Committee has not delegated authority to any other person to determine director compensation. Our management has made recommendations to the Committee regarding their views as to the appropriate amount and form of compensation (i.e. cash or stock) and tax and accounting ramifications of awards. In addition, the executive officers who serve on our Board vote on the recommendations for director compensation made by the Committee to the Board.
The Committee periodically reviews industry data from the National Association of Corporate Directors Director Compensation Report and Survey Data and evaluates industry averages, personal liability risks and other factors relating to director compensation. As of January 1, 2013, the annual retainer amount was $95,000. In November 2013, the Board approved an increase to the annual retainer to $97,850. On May 20, 2015, the Committee authorized the director compensation arrangement described below, which sets forth certain terms and conditions for director compensation but did not increase the amount of compensation.
Annual Retainer. Each non-management director is entitled to receive a $97,850 annual retainer, at least 51.5% of which is payable in stock (not to exceed any limits in the 2007 Plan) and the remainder of which is payable in cash. Prior to November 2013, that annual retainer was $95,000 at least half of which was payable in stock.
Initial Appointment or Election. Directors receive a one-time award of Stock Options to acquire 10,000 shares of our common stock upon initial appointment or election to the Board. The 10,000 amount reflects the 2:1 stock split of the Company’s Common Stock on March 14, 2014.
Chairperson Retainers. The Chairman of the Board and the Chairman of the Audit Committee each receive an annual retainer of $12,500, and the Chairperson of the Compensation Committee, the Chairman of the Finance Committee and the Chairman of the Nominating and Governance Committee each receives an annual retainer of $7,500 for their services in such positions. These amounts are all paid in cash.
Committee Service Retainers. Directors receive an annual retainer of $5,000, payable in cash, for each standing committee on which such director serves (unless such director is receiving compensation for acting as Chairman of such Committee, in which case no additional sum is paid). From time to time, the Board of Directors may also establish special committees. In 2013, Messrs. Gabbard, Johnson, Marcum and Smith each served on a special committee established by the Board. The Board approved additional compensation in 2013 in cash for their service on the special committee: Messrs. Gabbard, Johnson and Smith each received $30,000 and Mr. Marcum received $40,000. The special committee completed its obligations as delegated by the Board in October 2013. In 2013, Messrs. Marcum and Smith undertook an effort to restructure the Board to reflect the growth and changing nature of the Company. The Board approved additional compensation in 2013 in cash for their service as follows: Mr. Marcum received $50,000 and Mr. Smith received $30,000. The non-management director who is a member of the Stock Committee receives an annual fee of $1,500 paid in cash.

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 filedcurrently 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 Annual ReportCommon Stock. Accordingly, on Form 10-KMarch 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.

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 form partaddress 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 proxy solicitation material.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 available freeexpected 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 chargethe 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 FIFTH 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, April 8, 2020, April 9, 2021 and March 15, 2022 (the "TAPP"). If our stockholders do not approve the TAPP at the SEC's web siteAnnual Meeting, the TAPP will expire on December 31, 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, 2021, we had domestic tax attributes, including federal employer and general business credit carry-overs of approximately $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 March 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, 2022. If the stockholders approve the TAPP, it will expire on the earlier of (a) December 31, 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 Appendix 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.www.sec.gov 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"). Upon written request byIf issued, each fractional share of Series B Preferred Stock would 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 we will mail, without charge, a copy of the 2015 Form 10-K,Company, including, without limitation, any dividend, voting or liquidation rights.
Initial Exercisability. The Rights will not be exercisable until the financialearlier 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 and financial statement schedules, but excluding exhibitsissued with respect to uncertificated shares of Common Stock will evidence the Rights. Any transfer of shares of Common Stock prior to the 2015 Form 10-K. ExhibitsDistribution 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 2015 Form 10-KTAPP (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 availableor, 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 reasonable fee, which is limited to our expensesnumber 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 furnishingwhole, but not in part, at a price of $0.00001 per Right (the "Redemption Price"). The redemption of the requested exhibit. Such requestsRights may be made by writingeffective 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 our Corporate Secretary atexercise the address specified above.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, 2023, or (b) December 31, 2022 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" 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" 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 Fifth Amendment of the Tax Attributes Protection Plan.

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.

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.

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.

(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:

(iii)any and all Performance Stock Units and other Awards (if performance-based) shall vest (with the level of performance determined by the Committee) unless such Awards are assumed, converted or replaced by the continuing entity; provided, however, that in the event of a Participant’s termination of employment without Cause or termination with Good Reason within 12 months following the consummation of a Change in Control, any replacement awards shall fully vest upon such termination (with the level of performance determined by the Committee); provided, further, that the performance measures applicable to any assumed, converted or replaced award may, in the Committee’s discretion, (A) be determined based on performance achieved as of the date of the Change in Control, if determinable, (B) be determined based on a specified level of performance as of the date of the Change in Control, or (C) may be continued or adjusted to reflect such Change in Control.
(b)Cash-Out and Termination of Awards. The Committee may, in its sole discretion, provide that:
(i)all outstanding Awards shall be terminated upon the occurrence of a Change in Control and that each Participant shall receive, with respect to each Share subject to such Award, an amount in cash equal to the excess of the Fair Market Value of a Share immediately prior to the occurrence of the Change in Control over the Option Exercise Price or the SAR grant price, if applicable; and

47

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

(c)Awards Previously Granted. No termination, amendment or modification of the Plan or of any Award shall adversely affect in any material way any Award previously granted under the Plan without the written consent of the Participant holding such Award, unless such termination, modification or amendment is compensated by adequate consideration or required by Applicable Laws and except as otherwise provided herein.

(a)The Company, during the term of the Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.
(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.
(a)Interpretation. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular and the singular shall include the plural.

All references to "including" shall be construed as meaning "including without limitation."
48

(d)Governing Law. To the extent not preempted by federal law, the Plan, and all agreements hereunder, shall be construed in accordance with and governed by the laws of the State of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan to the substantive law of another jurisdiction.
(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. Any provision that would cause the Plan or any Award granted hereunder to fail to satisfy Section 409A shall have no force or effect until amended to comply with Section 409A, which amendment may be retroactive to the extent permitted by 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.
