Notes to Consolidated Financial Statements (Unaudited)

March 31, 2012

(1) Basis of Presentation

Nature of Operations

ADA-ES, Inc. (“ADA”), its wholly-owned subsidiaries, Advanced Emissions Solutions, Inc., a Delaware corporation (“ADES”) and ADA Intellectual Property, LLC, a Colorado limited liability company (“ADA IP”), both of which had no operations during the first quarter of 2013, BCSI, LLC, a Delaware limited liability company (“BCSI”), ADA Environmental Solutions, LLC, a Colorado limited liability company (“ADA LLC”) and ADA’s joint venture interest in Clean Coal Solutions, LLC (“Clean Coal”) are collectively referred to as the “Company”. The Company is principally engaged in providing environmental technologies and specialty chemicals to the coal-burning electric power generation industry. The Company generates a substantial part of its revenue from the sale of refined coal (“RC”), the sale of Activated Carbon Injection (“ACI”) and Dry Sorbent Injection (“DSI”) systems, contracts co-funded by the government and industry and the development and lease or sale of equipment for the RC market. The Company’s sales occur principally throughout the United States.

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. They do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. The consolidated financial statements include the financial statements of ADA, ADES, ADA IP, BCSI, ADA LLC and Clean Coal. All significant intercompany balances and transactions have been eliminated in consolidation.

In the opinion of management, the consolidated financial statements include all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of operations, financial position and cash flows for the interim periods presented. Operating results for the quarter ended March 31, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

These statements should be read in conjunction with the consolidated financial statements and related notes to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2012. The accounting policies used in preparing these consolidated financial statements are the same as those described in our Form 10-K.

The Company prepares its consolidated financial statements in conformity with U.S. generally accepted accounting principles. The preparation of these financial statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(3) Investment in Unconsolidated Entity

Clean Coal Solutions Services

On January 20, 2010, ADA, together with NexGen Resources Corporation (“NexGen”), formed Clean Coal Solutions Services, LLC (“CCSS”) for the purpose of operating Refined Coal (“RC”) facilities leased or sold to third parties. ADA has a 50% ownership interest in CCSS (but does not have management control of it) and ADA’s investment in and advances to CCSS which totaled $2.2 million as of March 31, 2013 includes its share of CCSS income since its formation and is accounted for under the equity method of accounting.

The following schedule shows CCSS’ unaudited consolidated summarized information as to assets, liabilities and revenues and ADA’s share of net income attributed to CCSS before consolidation. CCSS’ consolidated financial statements include the financial results of the entities that lease RC facilities and its revenues include the sale of RC and its cost of sales includes raw coal purchases.

4) Joint Venture Investment in Clean Coal

In November 2006, ADA sold a 50% interest in its joint venture Clean Coal to NexGen, which was formed in 2006 to market RC technology. In May 2011, ADA and NexGen entered into a transaction in which Clean Coal sold an effective 15% interest of the equity in Clean Coal to GSFS Investments I Corp. (“GSFS”), an affiliate of the Goldman Sachs Group, Inc. (“GS”), which is included in temporary equity subject to possible redemption in the consolidated balance sheets (see Note 8). GSFS has certain preferences over ADA and NexGen as to liquidation and profit distribution. GSFS has no further capital call requirements and does not have a voting interest but does have approval rights over certain corporate transactions.

In September 2011, ADA, NexGen and GSFS entered into a First Amendment to Second Amended and Restated Operating Agreement pursuant to which ADA and NexGen each transferred their 2.5% member interests in each of Clean Coal’s subsidiaries back to Clean Coal. As a result of these transactions, ADA’s interest in Clean Coal’s net profits and losses is 42.5%. This restructuring of ownership interests did not change the financial relationships of the parties and ADA still maintains a 50% governance interest in Clean Coal. In July 2012, ADA, NexGen and GSFS entered into a Second Amendment to the Operating Agreement (the “Operating Agreement”) which, among other things, expanded Clean Coal’s board of managers to allow for the appointment of an additional manager not directly representative of any of the members. Since its inception, ADA has been considered the primary economic beneficiary of this joint venture and has consolidated the accounts of Clean Coal.

Clean Coal’s function is to supply technology, equipment and technical services to cyclone-fired and other boiler users, but Clean Coal’s primary purpose is to put into operation facilities that produce RC that qualifies for tax credits that are available under Section 45 of the Internal Revenue Code (“Section 45 tax credits”). Clean Coal qualified two facilities in 2009 for such purposes and in June 2010 leased those facilities to GS RC Investments, LLC (“GS RC”), a related entity of GS.

In December 2010, the Tax Relief and Job Creation Act of 2010 extended the placed in service deadline for the Section 45 tax credits to January 1, 2012. In consideration of the extension, Clean Coal built and qualified an additional 26 RC facilities in 2011, which met the extended placed in service date. In November and December 2011, the two leased RC facilities qualified in 2009 were exchanged with newly constructed, redesigned RC facilities. The new leases carried over most of the substantive terms and conditions of the initial leases. In December 2012, the parties amended the leases to modify the lease term to month-to-month and in March 2013 the parties amended and restated the lease agreements to modify the structure and timing of the lease payments. The payments are due quarterly in advance and are subject to adjustments for inflation. Each lease has an initial non-cancellable term of two years and will automatically renew unless terminated at the option of the lessee thereof, for successive one-year terms through November 9, 2021 and December 10, 2021, as applicable. The parties also amended and restated the two Operating and Maintenance Agreements pursuant to which CCSS (subject to oversight by the lessee) operates and maintains the RC facilities to provide for the payment of a fixed fee under the agreements instead of payments based on the production of RC as had previously been in place.

Clean Coal leased two additional RC facilities in 2012, the third to an entity related to GS and the fourth to a third party investor. All agreements included terms and conditions substantially similar to those applicable to the first two leased RC facilities. On February 28, 2013, Clean Coal sold an RC facility to a new third party investor, bringing the total number of RC facilities leased or sold to five.

The Operating Agreement requires NexGen and ADA to each pay 50% of the costs of operating Clean Coal and specifies certain duties that both parties are obligated to perform. Pursuant to the Operating Agreement and Exclusive Right to Lease Agreement, GSFS is in the process of exercising its exclusive right (but not the obligation) to lease facilities that will produce up to approximately 12 million tons of RC per year on pre-established lease terms similar to those currently in effect for Clean Coal’s first two leased facilities.

Following is unaudited summarized information as to assets, liabilities and results of operations of Clean Coal:

Amounts due to CCSS

Clean Coal has recorded accounts payable to CCSS totaling $3.7 million and $3.5 million as of March 31, 2013 and December 31, 2012, respectively, which are included in accounts payable to related parties in the accompanying consolidated balance sheets.

5) Deferred Revenue and Deposits

Deferred revenue consists of:

•

billings in excess of costs and earnings on uncompleted contracts; and

•

deferred rent revenue related to Clean Coal’s lease and sale of its RC facilities.

Clean Coal Deferred Rent Revenue

As discussed in Note 4, in June 2010, Clean Coal executed agreements to lease two RC facilities to GS RC. These agreements provided for, among other things, a prepaid rent payment of $9 million for both RC facilities that was received before June 30, 2010. In November and December 2011, Clean Coal entered into transactions to exchange the existing facilities. There was no change to the prepaid rent payment or amortization period as a result of the exchange. Clean Coal received $1.5 million and $20 million in prepaid rents in 2012 and 2013, respectively, related to the additional leased and sold RC facilities.

Following is a table of current deferred revenue which is included in deferred revenue and other liabilities in the consolidated balance sheets and long-term deferred revenue which is included in deferred revenue in the consolidated balance sheets related to these rent revenues:


	As of March 31, 2013		As of December 31, 2012
	(in thousands)
Deferred revenue, short-term	$	11,514	$	625
Deferred revenue, long-term	$	13,259	$	875

The following table presents total rent revenues recognized and amortization with respect to the prepaid rents:


	Quarter Ended March 31,
	2013		2012
	(in thousands)
Rent revenue recognized	$	12,213	$	5,391
Amortization of prepaid rent included in amounts above	$	574	$	900

Clean Coal Deposits

During 2012 and 2011, Clean Coal received deposits of $6.3 million and $14.9 million, respectively from GSFS towards RC facilities which may be leased upon attainment of certain milestones. In October 2012, GSFS determined that it would not pursue leases on two particular RC facilities on which it had paid deposits totaling $4.7 million and concurrently gave notice for the return of the related deposits. In March 2013, Clean Coal returned the $4.7 million in deposits plus accrued interest to GSFS. Deposits of $16.5 million and $21.2 million are included in the consolidated balance sheets as of March 31, 2013 and December 31, 2012, respectively.

(6) Net Loss Per Share

Basic net loss per share is computed based on the weighted average common shares outstanding in the period. Diluted net loss per share is computed based on the weighted average common shares outstanding in the period and the effect of dilutive securities (stock options and awards) except where the inclusion is anti-dilutive.

All outstanding stock options (see Note 7) to purchase shares of common stock for the quarters ended March 31, 2013 and 2012 were excluded from the calculation of diluted shares, as their effect is anti-dilutive.

(7) Share Based Compensation

Since 2003, ADA has had several stock and option plans, including the 2005 Directors’ Compensation Plan (the “2005 Plan”), the Amended and Restated 2007 Equity Incentive Plan (the “2007 Plan”), the Amended and Restated 2010 Non-Management Compensation and Incentive Plan (the “2010 Plan”) and the ADA-ES, Inc. Profit Sharing Retirement Plan, which is a plan qualified under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”) as described below. These plans allow ADA to issue stock or options for shares of common stock to employees, Board of Directors and non-employees.

Following is a table of options activity for the quarter ended March 31, 2013:

During 2005, ADA adopted the 2005 Plan, which authorized the issuance of shares of common stock and the grant of options to purchase shares of common stock to non-management directors. Under the 2005 Plan, the award of stock is limited to not more than 1,000 shares per individual per year, and the grant of options is limited to 5,000 per individual in total. The aggregate number of shares of common stock reserved for issuance under the 2005 Plan totals 90,000 shares (50,000 in the form of stock awards and 40,000 in the form of options). In October 2012 and February 2013, two new Board members were issued 5,000 options each under the 2005 Plan.

The 2007 Plan, which was adopted by ADA in 2007, was 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 15,000 shares of common stock from 10,000 shares. On July 19, 2012, the stockholders of ADA approved an amendment to the 2007 Plan to increase the number of shares presently issuable to 1.3 million and increase the number of shares authorized for issuance to 1.8 million. In addition, the stockholders also approved an increase in the number of shares with respect to which awards may be granted in any fiscal year from 30,000 to 50,000 and the annual grant limit for the non-management director annual grant was increased to 30,000 shares. The 2007 Plan authorizes the issuance to employees, directors and non-employees shares of common stock, either as restricted stock grants or to underlie options to purchase shares of ADA’s common stock.

In 2009, ADA revised its 401(k) Plan. The revision permits ADA to issue shares of its common stock to employees to satisfy its obligation to match employee contributions under the terms of the plan in lieu of matching contributions in cash. ADA reserved 300,000 shares of its common stock for this purpose. The value of common stock issued as matching contributions under the plan is determined based on the per share market value of ADA’s common stock on the authorization date.

The 2010 Plan, which was adopted by ADA in 2010, was amended and restated as of July 19, 2012 to make non-material changes to assure Internal Revenue Code Section 409A compliance. The Plan permits grants of awards, which may be shares, rights to purchase restricted stock or bonuses of restricted stock or other rights or benefits under the Plan.

Following is a table summarizing the activity under various stock issuance plans for the quarter ended March 31, 2013:

(8) Temporary Equity Subject to Possible Redemption

As described in Note 4, in May 2011, ADA and NexGen entered into a transaction in which Clean Coal sold an effective 15% interest of the equity in Clean Coal to GSFS. Approximately 15.8 units of non-voting Class B membership interests were issued to GSFS for $60 million in cash. ADA and NexGen each received $30 million as a result of the sale. The terms of the Operating Agreement permit GSFS to require redemption of the unreturned portion of its initial $60 million investment in Clean Coal plus a return of 15% in 2021 and under certain limited circumstances. As a result, $60 million is classified as temporary equity subject to possible redemption in the consolidated balance sheets.

(9) Stockholders’ Deficit

The non-controlling interest portion of stockholders’ deficit includes the non-controlling interest related to Clean Coal.

(10) Commitments and Contingencies

Line of Credit

Clean Coal has a revolving line of credit with a bank for $15 million secured by the equity interests and proceeds related to such equity interests of each subsidiary owned by Clean Coal. In January 2013, the revolving line of credit agreement was amended to provide a $2 million revolver with any borrowings under the amended agreement due on December 31, 2013. The increased commitment is secured by the equity interests and proceeds related to such equity interests of each subsidiary owned by Clean Coal. There was no outstanding balance under this agreement at March 31, 2013.

In May 2012, an amendment was made to the line of credit agreement to increase the amount available by $3 million under an increased commitment note issued in conjunction with the line of credit. This amount was secured by a cash collateral account of $3 million held by the bank issuing the line of credit with funds received equally from ADA and NexGen. The agreement was amended in December 2012 to extend the term of the agreement until June 1, 2013. There was no outstanding balance under this amendment at March 31, 2013 and outstanding cash collateral deposits were returned during the quarter then ended. Borrowings under the increased commitment notes are subject to certain financial covenants applicable to Clean Coal.

Retirement Plan

ADA assumed the 401(k) plan covering all eligible employees as of January 1, 2003 which was revised in 2009, and makes matching contributions to the plan in the form of cash and its common stock. Such contributions are as follows:

Performance Guarantee on Emission Control Systems

Under certain contracts to supply emission control systems, the Company may guarantee certain aspects of the performance of the associated equipment for a specified period to the owner of the power plant. The Company may also guarantee the achievement of a certain level of mercury removal based upon the injection of a specified quantity of a qualified activated carbon (“AC”) at a specified rate given other plant operating conditions. In the event the equipment fails to perform as specified, the Company may have an obligation to correct or replace the equipment. In the event the level of mercury removal is not achieved, the Company may have a “make right” obligation within the contract limits. The Company assesses the risks inherent in each applicable contract and accrues an amount that is based on estimated costs that may be incurred over the performance period of the contract. Such costs are included in the Company’s accrued warranty and other liabilities in the consolidated balance sheets. Any warranty costs paid out in the future will be charged against the accrual. The adequacy of the warranty accrual balance is assessed at least quarterly based on the then current facts and circumstances and adjustments are made as needed.

The changes in the carrying amount of the Company’s performance guaranties are as follows:


	Quarter Ended March 31,
	2013			2012
	(in thousands)
Beginning balance	$	668		$	547
Performance guaranties accrued		154			1
Expenses paid		(8	)		(2	)

Ending balance	$	814		$	546

In some cases, a performance bond may be purchased and held for the period of the warranty as an alternative to satisfy the obligation.

Clean Coal

The Company also has certain obligations in connection with the activities of Clean Coal. ADA, NexGen and two entities affiliated with NexGen have provided GS RC with joint and several guaranties (the “CCS Party Guaranties”) guaranteeing all payments and performance due under the related transaction agreements. ADA also entered into a contribution agreement with NexGen under which any party called upon to pay on a CCS Party Guaranty is entitled to receive contribution from the other party equal to 50% of the amount paid.

GS RC has provided Clean Coal with a guaranty as to the payment only if all the initial term fixed rent payments and the renewal term fixed rent payments under the related leases, which, although terminable at any time, cannot be terminated without the substitution of such guaranty with another guaranty on similar terms from a creditworthy guarantor.

Arbitration Award Liabilities

As previously reported in various filings, ADA had been engaged in litigation with Norit Americas, Inc. and Norit International N.V. f/k/a Norit N.V. (“Norit”). The Norit lawsuit initially filed in Texas was moved to arbitration, and on April 8, 2011, the arbitration panel issued an interim award holding ADA liable for approximately $37.9 million for a non-solicitation breach of contract claim and held ADA and certain other defendants liable for royalties of 10.5% for the first three years beginning in mid-2010 and 7% for the following five years based on adjusted sales of AC from the Red River plant. The Company recorded $679,000 and $284,000 in royalty expense for the quarters ended March 31, 2013 and 2012, respectively, related to this award.

On August 29, 2011, ADA and Norit entered into a settlement agreement whereby ADA paid a lump-sum payment to Norit totaling $33 million on August 30, 2011. In addition, ADA agreed to pay an additional $7.5 million over a three-year period commencing on June 1, 2012, payable in three installments without interest of $2.5 million. Under the terms of the settlement agreement, ADA is also required to pay the royalty noted above and a lesser royalty on certain treated activated carbons. Payments of amounts due under the royalty award for each quarter are payable three months after such quarter ends. On October 18, 2011, the arbitration panel endorsed and confirmed the terms of the settlement agreement.

The Company has accrued a current liability as of March 31, 2013 of $3.2 million which is included in settlement awards and related accrued liabilities and a long-term liability of $2.5 million which is included in settlement awards and indemnity liability in the consolidated balance sheets related to this agreement.

Indemnity Liability Settlement

As previously reported in various filings, in November 2011, ADA entered into an Indemnity Settlement Agreement whereby ADA agreed to settle certain indemnity obligations asserted against ADA related to the Norit litigation. Under the terms of the Indemnity Settlement Agreement, ADA paid ADA Carbon Solutions, LLC (“Carbon Solutions”) a $2 million payment on November 28, 2011 and agreed to make 16 additional monthly payments of $100,000 with the first one paid on November 28, 2011, and the remaining 15 payments commencing on December 1, 2011, relinquished all of its equity interest in Carbon Solutions to Carbon Solutions and amended the Intellectual Property License Agreement dated October 1, 2008 between ADA and Carbon Solutions. The final payment under this agreement was made in February 2013.

(11) Income Taxes

Income taxes are accounted for under the asset and liability approach. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using the enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided if and when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. At each reporting date, management reviews existing income tax assessments and, if necessary, revises them to reflect changed circumstances. In a situation where recent losses have been incurred, the accounting standards require convincing evidence that there will be sufficient future taxable income to realize deferred tax assets.

The Company has provided a full valuation allowance against the deferred tax assets of $40.1 million and $39.5 million as of March 31, 2013 and December 31, 2012 respectively, to reflect the estimated amount of deferred tax assets that may not be realized. The ultimate realization of deferred tax assets is dependent upon generation of future taxable income during the periods in which those temporary differences become deductible. Management considers both positive and negative evidence and tax planning strategies in making this assessment.

(12) Business Segment Information

The following information relates to the Company’s three reportable segments: Refined coal (“RC”), Emission control (“EC”) and CO₂ capture (“CC”).

All assets are located in the U.S. and are not evaluated by management on a segment basis. All significant customers are U.S. companies and the U.S Government.

Overview

The Company is a leader in clean coal technologies and associated specialty chemicals, primarily serving the coal-fueled power plant industry. Our proprietary environmental technologies and specialty chemicals enable power and coal-fired plants to enhance existing air pollution control equipment, minimize mercury, CO₂ and other emissions, maximize capacity and improve operating efficiencies to meet the challenges of existing and pending emission control regulations. We have three operating segments: RC (refined coal), EC (emission control) and CC (CO₂ capture).

The RC segment includes revenues from the lease or sale of RC facilities and RC sales which approximate the cost of raw coal acquired for RC facilities operated for our own account. The EC segment includes revenue from the supply of emissions control systems including activated carbon injection (“ACI”) systems, dry sorbent injection (“DSI”) systems to control SO₂, SO₃ and HCl and flue gas conditioning systems, the licensing of certain technology and provision of consulting services. The CC segment includes revenue from projects relating to the CO₂ capture and control market, including projects co-funded by government agencies, such as the DOE and industry supported contracts.

Our RC segment generates revenues through the lease or sale of RC facilities that produce RC intended to qualify for Section 45 tax credits to third party investors, as well as operating RC facilities and keeping the tax credits for our own and our partners’ accounts. To date, 28 RC facilities have been “placed-in-service” through Clean Coal, our RC joint venture with NexGen Refined Coal, LLC (“NexGen”), an affiliate of NexGen Resources Corporation, and with GSFS Investments I Corp. (“GSFS”), an affiliate of The Goldman Sachs Group, Inc. (“GS”). Unless Congress again extends the placed-in-service deadline for such facilities, which has passed, we have no ability to place any more RC facilities into service.

The primary drivers for many of our EC products and services are environmental laws and regulations impacting the electric power generation industry and other coal users. Environmental regulations, such as the 1990 Clean Air Act Amendments, the MATS regulations, various Maximum-Achievable Control Technology (“MACT”) standards including the Industrial Boiler MACT (“IBMACT”) regulations, the Cement MACT regulation, various state regulations and permitting requirements for coal-fired power plants are requiring electric power generators and others to reduce emissions of pollutants, such as particulate matter, SO_2,NO_x, mercury and acid gases. We are a key supplier of mercury control equipment and services, which includes ACI systems and chemical additives, to the EC market whose commercial equipment component first began in 2005 when several individual states began to require limits on mercury emissions. We also offer DSI systems to control SO₂ and acid gases such as HCl and SO₃.

We conduct research and development efforts in CO₂ capture and control from coal-fired boilers and other technologies that we believe may have future commercial markets. In September 2010, we signed our second significant contract related to CO₂ capture with the DOE, for a project that is expected to continue through the end of 2014.

Refined Coal

We are marketing our CyClean and M-45 technologies, services and equipment exclusively through our joint venture Clean Coal.

Environmental Legislation and Regulations

Clean Coal’s primary opportunity is based on the availability of Section 45 tax credits established by the American Jobs Creation Act of 2004, and as amended by the Emergency Economic Stabilization Act of 2008, the American Recovery and Reinvestment Act of 2009, and the Tax Relief and Job Creation Act of 2010, the last of which extended the placed-in-service deadline for the Section 45 tax credits from its original date to January 1, 2012. The 2013 tax credit amounts to $6.59 per ton of RC and is expected to escalate annually through 2021. In December 2009, the Internal Revenue Service (the “IRS”) issued the initial guidance as to the specifics concerning how the emissions reductions are to be measured and certified to demonstrate compliance necessary for RC production to qualify for the Section 45 tax credits. The IRS provided subsequent guidance on October 4, 2010 to address various issues that had arisen. Additionally, the IRS has published a number of PLRs that provide approval to specific taxpayers on matters related to the Section 45 tax credit issues addressed in the PLRs. Although the approval in each PLR only applies to the taxpayer and the specific project mentioned in the PLR, other taxpayers can gain an understanding on how the IRS interprets certain matters based on the conclusions reached in the PLR.

Use of any tax credits is subject to potential IRS audits of the entity that claims the credits on its tax return. If such use is challenged, negotiated/structured settlements may be reached with the IRS. In some cases, where the parties cannot reach agreement and the matter is litigated, court rulings may impact various aspects of the RC business including the viability of the market for Section 45 tax credits in general, the perceived risk involved in the allocation of Section 45 tax credits and thus the amount a third party would be willing to invest for the opportunity to produce RC and generate tax credits and the structure of contracts that we enter into to recognize value from our RC facilities.

Technology License Agreements

ADA licensed to Clean Coal, on an exclusive basis, the CyClean technology in November 2006. On July 27, 2012 ADA licensed the M-45 technology (the “M-45 License”) to Clean Coal in order to leverage Clean Coal’s operating expertise and take advantage of the other synergies that can be obtained by Clean Coal having the ability to provide and use either the CyClean or M-45 technology.

In addition, the M-45 License gives Clean Coal, on a limited, non-exclusive, non-transferable, royalty-bearing basis, the right to sublicense (under specified terms to be approved by ADA prior to the sublicense being granted) to limited utilities that purchase or have purchased RC produced using the M-45 technology, the right to use the M-45 technology under certain circumstances for the purpose of “Mercury Only Emission Control”.

The M-45 License runs from July 27, 2012, through the latest of the expiration of (i) the Section 45 tax credits, (ii) any similar tax credit subsequently enacted, after the effective date of the agreement up to within one year of the expiration of the Section 45 tax credits, which tax credit provides for the production of a coal-based fuel (pre-combustion) that emits, when combusted, a lower level of both NOx and mercury emissions, and (iii) the date on which Clean Coal and all sublicensees of the M-45 technology have permanently ceased to provide Mercury Only Emission Control.

Pursuant to the M-45 License, we receive royalties equal to (i) a percentage of the per-ton, pre-tax margin from RC produced with the M-45 technology from leased or sold RC facilities, (ii) a percentage of the Section 45 tax credits claimed by Clean Coal (or a Clean Coal affiliate), or their respective owners, on RC produced by a facility that Clean Coal does not sell or lease to a third party and instead operates to retain the Section 45 tax credits from that facility for its (or an affiliate’s) own benefit, net of all directly allocable operating expenses and all utility payments incurred by Clean Coal (or an affiliate) in connection with the production and sale of such RC, and (iii) a percentage of the revenue, net of all direct expenses, received by Clean Coal as a direct result of Clean Coal’s exercise of the license for Mercury Only Emission Control described above. ADA received $10 million in prepaid royalty deposits as a result of attainment by Clean Coal of certain milestones, consisting of the initial payment of $2 million made at signing of the non-binding term sheet for the M-45 License in November 2011 and an additional $8 million received in March 2013. We have certain obligations to provide technical assistance to Clean Coal and its sublicensees during the term of the M-45 License, as well as certain obligations to protect and maintain the patents that underlie the M-45 technology and to indemnify Clean Coal against certain claims related to the technology. The income and expense related to these royalties are eliminated in consolidation of the financial results of Clean Coal.

Leased and Operating RC Facilities

Clean Coal initially placed two RC facilities in service prior to the initial placed-in-service deadline of January 1, 2010 and demonstrated the required emission reductions for their RC product to qualify for the Section 45 tax credits. On June 29, 2010, Clean Coal signed agreements to lease these two RC facilities through its wholly owned subsidiaries (the “Lessors”) to GS RC Investments, LLC (“GS RC”) with initial two and one half year terms and annual renewals that were set to expire in 2019. In November and December 2011, Clean Coal, the Lessors and GS RC entered into two Exchange Agreements pursuant to which the parties exchanged the leased RC facilities at each power plant with newly constructed, redesigned RC facilities which resulted in termination of the original leases and entry into new lease agreements (the “Exchange Transactions”). The new leases carried over most of the substantive terms and conditions of the initial leases and initially had annual terms that would have automatically renewed through December 31, 2021. The two facilities are installed at two different power plants in the Midwest each of which operates two cyclone boilers burning Powder River Basin (“PRB”) coal from Wyoming.

GS RC also entered into supply agreements for each RC facility pursuant to which it supplies RC to the applicable power plant owner. Clean Coal Solution Services (“CCSS”), a Colorado limited liability company owned 50% by us and 50% by NexGen, (subject to oversight by GS RC) operates and maintains the RC facilities under two Operating and Maintenance Agreements entered into with GS RC in June 2010. CCSS also arranges for the purchase and delivery of certain chemical additives necessary for GS RC’s production of RC under the supply agreements. The term of each such agreement runs coincident with the leases. These agreements were amended in November and December 2011 in connection with the Exchange Transactions.

In addition, pursuant to the Exchange Transactions, we, NexGen and two entities affiliated with NexGen provided GS RC with joint and several guaranties (the “CCS Guaranties”) guaranteeing all payments and performance due under the agreements described above. We also entered into a contribution agreement with NexGen under which any party called upon to pay on a CCS Guaranty is entitled to receive contribution from the other party equal to 50% of the amount paid. GSFS, GS RC’s parent, provided Clean Coal with a guaranty as to the payment of all fixed rent payments under the leases, which, although terminable at any time, cannot be terminated without the substitution of such guaranty with another guaranty on similar terms from a creditworthy guarantor.

In March 2013 the parties amended and restated the Exchange Transaction lease agreements to change certain terms and timing of the lease payments. The payments are now due quarterly in advance and are subject to adjustments for inflation. Each lease has an initial non-cancellable term of two years and will automatically renew unless terminated at the option of the lessee for successive one-year terms through November 9, 2021 and December 10, 2021, as applicable. Revenues to Clean Coal are expected to remain at similar levels as seen under the prior written agreements. The parties also amended and restated the two Operating and Maintenance Agreements to provide for the payment of a fixed fee under the agreements instead of variable payments based on the production of RC.

In connection with an Exclusive Right to Lease Agreement between Clean Coal and GSFS (the “Lease Agreement”), Clean Coal granted GSFS the exclusive right (but not the obligation) to lease additional RC facilities that will produce up to approximately 12 million tons (+/- 10%) (the “Target Tons”) of RC per year on pre-established lease terms similar to those in effect at the time for

Clean Coal’s two then-existing leased RC facilities, but which are more economically favorable to Clean Coal than the rates in the leases for the existing RC facilities that Clean Coal leased to GS RC in June 2010. Under the Lease Agreement, Clean Coal is required to submit a package to GSFS with respect to each RC facility it proposes that GSFS consider for leasing (being all RC facilities developed by Clean Coal until the Target Tons are met), and upon certification and acceptance of the certification for a given RC facility by GSFS, GSFS is required to pay Clean Coal, as a deposit, an agreed amount for each 1 million tons of projected annual RC production.

Upon closing of such a lease of an RC facility from Clean Coal, GSFS is required to pay Clean Coal an additional amount per 1 million tons of projected annual RC production from the leased RC facility. These payments are paid as advance rent, and actual amounts due under the leases (with true-ups) are paid in accordance with the operative lease and related agreements. If GSFS determines that it will not lease an RC facility after it has paid the deposit, it can provide notice requesting the return of the deposit paid for that RC facility, and the deposit must be returned within 30 days of the end of the quarter in which the notice is given. The amount of any deposit will earn interest from the date of the notice until the deposit is returned.

Clean Coal received $14.9 million from GSFS in 2011 as initial deposits for more than the Target Tons. In October 2012, GSFS determined that it would not pursue leases on two specific RC facilities on which it had paid deposits totaling $4.7 million and concurrently gave notice for the return of the related deposits. In December 2012, GSFS agreed to defer the return of the deposits until April 30, 2013. In March 2013, Clean Coal returned the $4.7 million in deposits plus accrued interest to GSFS.

Pursuant to the Lease Agreement, Clean Coal leased a third RC facility in the first quarter of 2012 to another entity related to GS. Clean Coal leased a fourth RC facility to another third party investor during the third quarter of 2012. All agreements included terms and conditions substantially similar to those applicable to initial leases for the first two leased RC facilities. On February 28, 2013, Clean Coal sold an RC facility to a new third party investor, bringing the total number of RC facilities leased or sold to five. The structure of the sale was similar to that of the initial leases and provided the buyer with the right to require Clean Coal to repurchase the RC facility for a nominal fee in certain situations. The terms of the sale included $20 million paid immediately to Clean Coal and a combination of fixed and variable payments going forward. An additional $5 million is to be paid to Clean Coal when the buyer receives an applied-for PLR from the IRS, which is expected later this year.

In addition to the four leased RC facilities and the fifth RC facility sold to a third party investor, Clean Coal currently operates three additional RC facilities for its own account, resulting in its owners’ ability to claim the Section 45 tax credits for the RC produced during those operations. We expect the largest of those facilities to be leased to one of the existing third party investors within the first half of 2013.

With the four leased RC facilities, the fifth RC facility sold to a third party investor and the three RC facilities currently operated by Clean Coal for its own account, there are currently eight RC facilities in routine operations on 15 coal-fired boilers that, in the aggregate, have historically burned more than 20 million tons of coal per year. One of Clean Coal’s goals is to process RC as high a percentage of coal made available to it as possible. During the first quarter of 2013, RC facilities operated by Clean Coal for its own account produced approximately two million tons of RC.

Clean Coal plans to retain and operate one or two of the currently operating RC facilities continously for its own account and in the longer term a number sufficient to claim Section 45 tax credits for one of every five tons of RC produced by all RC facilities going forward. During the first quarter of 2013, the RC facilities operated for Clean Coal’s account generated $45 million in revenues from RC sales which were offset by $45 million in raw coal costs and generated $12.6 million in Section 45 tax credits that can be used to offset future tax expenses of its owners. ADA’s portion of these credits amounts to $5.4 million. Clean Coal is in negotiations to lease or sell several additional RC facilities with a goal to have all RC facilities in operation by the end of 2014 utilizing the CyClean and M-45 technologies.

In those cases where Clean Coal chooses to operate an RC facility for its own account, either on an interim basis or for the long-term, it receives the benefit of the Section 45 tax credits from the RC produced at the facility. As part of those operations Clean Coal purchases raw coal, refines the raw coal into RC and then sells the RC to the power plant, generally at the same price per ton, recognizing revenue from the RC sale and costs of revenue for the raw coal purchased. These amounts may be significant as the average per ton price for the raw coal purchased and RC sold has historically ranged from $20 to $40 per ton. In those operations Clean Coal also pays, recognizing as an expense, and may also deduct for tax purposes, operational costs, a fee to the utility for coal handling and a fee for the land used to site the RC facility. For the RC facilities that Clean Coal operates for its own account, it incurs operating expenses of approximately $3 per ton of coal treated and generates approximately $7.50 per ton in tax benefits.

In those cases where Clean Coal chooses to lease or sell an RC facility to a third party investor, once the final utility site and the third party investor have been determined, it takes approximately six to twelve months to obtain environmental permits for full-time operation, secure necessary approvals from state Public Utility Commissions, and negotiate and complete all necessary contracts. PLRs may be needed from the IRS if requested by the third party investor, which may take several additional months to obtain after formal contracts are completed.

Closings of several deals with utilities and third party investors for our RC facilities were delayed in 2012 for various reasons, including: permitting, regulatory approval, corporate financial restructuring of utilities or third parties involved in some aspect of the transaction, changes in plant ownership, changes and retirements of personnel involved in the negotiations, involvement of additional parties in the transactions, and uncertainties in the tax credit community. As our previous disclosures have indicated, because of the complexities of each RC deal and the number of externalities that are outside our direct control and involvement, we may experience delays beyond our initial estimates of six to twelve months to close the transactions.

We expect that future transactions for RC facilities not presently operating may be either lease or sale transactions with the purchase price payable over time. However, regardless of the form the final transaction structures will provide long-term economic benefits substantially similar to those provided by the prior lease transactions. However, the economics of each facility will be unique as the revenue and expected margins will differ from one RC facility to another depending upon, among other factors, the size of the power plant that the facility serves, the amount of RC produced at the plant and the expenses incurred, including the cost of chemicals, labor costs, negotiated payments to the utility, upfront prepaid rent payments and royalty payments for the license of certain technologies. As is generally the case in these transactions, the sale or lease of the RC facilities involves a relationship between the utility, a third party investor and Clean Coal. By buying or leasing the RC facility and producing RC, the third party investor becomes the producer of RC, receives the benefit of the annually escalating per ton Section 45 tax credit and is able to deduct depreciation and/or a portion or all of the lease payments. In return it pays, and may also deduct, a portion or all of the fees to the utility for coal handling and land use to site the RC facility and operational costs. In addition, the third party investor pays a mutually agreed combination of fixed and contingent rents or fixed rents only, to Clean Coal for the lease of the RC facility. In the case of a sale, the overall economics of the payments made are substantially similar to the fixed and/or contingent rents paid under the initial leases. In addition to the site and coal handling payments, the utility receives the benefit of the resulting mercury and NOx reductions which have an estimated value of between $1.00- $4.00 per ton of RC burned.

Since its inception, ADA has been considered the primary economic beneficiary of Clean Coal and has consolidated its accounts in our financial statements, but we do not consolidate the accounts of CCSS because NexGen controls the entity pursuant to the operating agreement of the entity. Clean Coal’s total annual contribution to our operating income will ultimately depend on the utilities’ use of coal in the generation of electricity, which use will likely fluctuate over the term of the Section 45 tax credits. In order to maintain our interest in Clean Coal, we are obligated to fund half of its operating costs and capital expenditures.

Status of Remaining RC Facilities

Our goal is to place into full time operations the remaining RC facilities as soon as possible with an expectation that all will be in operation by the end of 2014. For the remaining facilities, there are a number of possible locations all with different sizes and characteristics. As a result, it is difficult to provide explicit guidance at this time as to the timing, location and likelihood of their permanent placement. For example, we are holding five facilities in reserve for placement at five very large potential RC production sites. Each of these sites has its own unique set of circumstances and issues that will likely require some change in operations at the utility or other changes such as technology improvements, switch in coal rank, or obtaining a PLR from the IRS, in order for those facilities to begin full time operation. In this regard we have made significant progress in expanding the potential target market by extending our RC technologies beyond cyclone boilers and PRB coals. Clean Coal is currently operating two RC facilities using the M-45 technology at plants burning Gulf Coast lignite and one RC facility using the CyClean technology at a plant burning North Dakota lignite. In addition, tests have demonstrated the potential to apply these RC technologies to bituminous coals. Clean Coal has successfully conducted tests on an improvement to the M-45 technology (referred to as M-45-PC^TMtechnology) that was certified by an independent professional engineer as eligible for the Section 45 tax credit in late 2012 and is available for use on pulverized coal (“PC”) boilers. The ability to use the M-45 technology on PC boilers significantly increases the potential market for locations where the RC facilities could be located as PC boilers represent over 80% of the 1,200 electricity generating boilers in the U.S. and there are over 50 plants where it may be possible to treat five to ten million tons of coal per year with a single RC facility. The tax credit rules further allows us to change the process by which coal is refined and use the RC facilities at plants other than those at which they were originally placed into service. We believe that the first RC facilities using M-45-PC technology could be put into full-time operation later this year.

We believe that once all new and existing RC facilities, other than those retained by Clean Coal and operated for its own account, are leased or sold to third party investors and become fully operational, they will achieve an annualized segment rental revenue rate of approximately $200 million; this revenue figure excludes approximately $250 million to $300 million in ongoing coal sales and raw coal purchases for RC facilities that Clean Coal is expected to operate in the long-term for its own account. These revenue rates would be expected to eventually generate approximately $100 million in segment income to the Company after payments to joint venture partners, including an estimated $30 million in tax credits (the Company’s share) to be generated by RC facilities operated by Clean Coal. The projected segment revenue and income are expected to continue through 2021.

From now through 2014, we expect leases and sales of new RC facilities to generate significant cash receipts from prepaid rent and upfront purchase price payments for Clean Coal. For the RC facilities that it retains and operates for its own account, Clean Coal will record operating costs, coal sales and costs of coal that may be significant. This will result in increased expenses and revenues over and above the increased revenue recognized from the lease and sale of additional RC facilities and will reduce gross margin as a percent of total revenues. The ultimate benefit from these retained facilities is derived from the tax benefits they generate which amounts to approximately $7.50 per ton of RC produced.

Emission Control

Power companies have started to procure ACI and DSI systems to comply with new emission regulations and the Company is currently maintaining its market leading positions in both ACI and DSI awards. We continue to receive requests to evaluate mercury and acid gas control options at a number of plants. We expect to see additional ACI and DSI revenues as contracts are awarded on the outstanding proposals (see discussion below).

Environmental Legislation and Regulations

Mercury has been identified as a toxic substance and, pursuant to a court order, the U.S. Environmental Protection Agency (“EPA”) issued regulations for its control from power plants in March 2005, which was known as the “Clean Air Mercury Rule” or “CAMR.” CAMR was subject to significant challenges and was ultimately declared invalid. In April 2010, the U.S. District Court of Appeals of the District of Columbia approved the consent agreement reached between the EPA and a coalition of public health and environmental groups that sued in 2008 to force the agency to set tighter emission limits. That settlement required the EPA to issue a draft rule in March 2011 and a final rule requiring strict plant-specific controls for power plants’ toxic air pollutants no later than November 16, 2011. On March 16, 2011, the EPA issued the draft of the proposed MATS rule, a MACT-based hazardous pollutant regulation applicable to coal and oil-fired electric utility steam generating units (“EGU”), which provides for, among other provisions, control of mercury and volatile metals such as arsenic, selenium and control of acid gases such as HCl and other Hazardous Air Pollutants (“HAPs”). On October 28, 2011, the EPA, with approval of the environmental groups who were parties to the Court of Appeals consent, extended the deadline and the final rule was issued on December 16, 2011, and took effect on April 16, 2012. After reconsidering certain aspects of the MATS relating to new source standards due to various lawsuits, the EPA issued the final rule for new source standards on March 28, 2013. We believe these lawsuits will not impact our ongoing business, which is focused on existing sources of HAPs.

The MATS for existing HAP sources establishes standards for all HAPs emitted by coal and oil fired EGUs with a capacity of 25 megawatts or greater. Units with lower generating capacities will instead fall under the IBMACT rule scheduled to go into effect on January 31, 2016. The standards are based upon the average of the best performing 12% of existing applicable power plants. The MATS provides the option to use facility-wide averaging of 90 days to meet the limits for mercury emissions, which is 1.2 pounds per trillion BTU (1.0 pound per trillion BTU if 90 day averaging is used). This emission limit corresponds to the capture of up to 80-90% of the mercury in the coal burned in electric power generation boilers as measured at the exhaust stack outlet for most coals having a greater than 8,500 BTU per pound heat rate. For plants burning lower rank coals such as lignite, the emission limit is 4.0 pounds per trillion BTU. The EPA estimates that there are approximately 1,200 coal-fired units and 300 oil-fired units affected by the MATS. Existing sources must comply with the MATS standards by April 16, 2015. An authorized state permitting authority has the ability to grant sources up to a one year extension, on a case by case basis, if such additional time is necessary for the installation of controls.

In addition to issuing standards covering electric power generators, the EPA has developed a MACT-based mercury emissions regulation for the Portland cement industry through amendments to the National Emission Standards for HAPs (the “Cement MACT”). The Cement MACT regulation was initially finalized on August 6, 2010. On May 11, 2011, the EPA denied requests to issue an administrative stay on the Cement MACT and denied in part and granted in part various petitions to reconsider the final revised Cement MACT. The EPA published the final Cement MACT regulation on February 12, 2013 with compliance required by September 9, 2015. The standards for new kilns apply to facilities where construction, modification, or reconstruction commenced after May 6, 2009.

The Cement MACT requires cement plants to reduce HAPs by September 9, 2015 including 92% of mercury emissions and 83% of hydrocarbons emissions. This regulation could require ACI systems on up to 90 cement kilns in the U.S., which are owned by approximately 15 companies. We have been engaged in several testing programs for cement companies to define their emissions and evaluate how ACI equipment and sorbents will work in that industry. The tests were designed to evaluate the effectiveness of collecting mercury and organics from cement kiln exhaust gas streams. The EPA also issued a new IBMACT regulation for coal-fired boilers that provide mostly steam and/or electricity for small industrial and institutional power needs with no more than 25 megawatts of electricity sold to the grid per year. The final regulation was released on February 23, 2011 and issued on March 21, 2011, with compliance deadlines originally scheduled for early 2014. On December 23, 2011, the EPA issued proposed reconsiderations of certain aspects of the IBMACT, including clarification of applicability and implementation issues.

The final IBMACT rule which was published on January 31, 2013 could impact over 600 existing coal-fired industrial boilers, which have until January 31, 2016 to comply. The final emission limit of 5.7 pounds of mercury per trillion BTU of heat input for existing and 0.80 pounds per trillion BTU of heat input for new coal-fired industrial boilers on average requires no less than 50% capture of mercury from coal-fired boilers burning various coals. However, we believe the final IBMACT could significantly increase the market for DSI systems when considering the requirements to also limit HCl emissions to levels of 0.022 pounds per million BTU.

The Clean Air Act requires that all emission control-related regulations be met within three years from the final date the new rule is posted in the Federal Register, with the potential extension of one year granted by individual states on a case by case basis. We believe that substantial long-term growth of the EC market for the electric power generation industry will most likely depend on how industry chooses to respond to the pending and new federal regulations. In general, all three of these regulations are less stringent than originally expected, meaning more flexibility for operators subject to the rules in choosing low capital expenditure (“CAPEX”) emissions control technologies and likely fewer forced plant retirements from having to install large CAPEX emission control equipment such as scrubbers and baghouses. We believe the MATS and MACT rules will create a large market for our emission control and RC products.

On December 15, 2009, the EPA issued an endangerment finding that triggered a Clean Air Act requirement that the agency regulate CO₂ emissions from stationary sources such as power plants. Industry and states have filed an extensive consolidated litigation before the U.S. Court of Appeals for the District of Columbia Circuit challenging numerous aspects of EPA’s Greenhouse Gas (“GHG”) rules. The court is considering arguments regarding the EPA’s guidance memo on the timing of GHG regulations, such as when GHGs become a “regulated pollutant” under the Clean Air Act and thus if and when New Source Review and Prevention of Significant Deterioration regulations would apply. On March 27, 2012, the EPA proposed its first new source performance standards for CO₂ emissions from new power plants as a result of a separate settlement with states and environmental groups in 2010.

Activated Carbon Injection and Dry Sorbent Injection Systems

ACI systems are currently the most established and accepted technology to specifically control mercury emissions and have been widely deployed to meet the existing state and new plant regulations. In addition to ACI systems for mercury control, we have developed and are providing commercial DSI systems that inject dry alkaline sorbents to control acid gases such as SO₃ and HCl. Our DSI technology is also used to control SO₂, one of six criteria air pollutants. The use of DSI for SO₃ reduction has also been shown to enhance the capture of mercury from bituminous coal-fired boilers.

In order to meet the expected demand in the ACI and DSI markets, on August 31, 2012, our wholly owned subsidiary BCSI, LLC acquired the assets of Bulk Conveyor Specialist Inc., a leading privately held fabricator and supplier of DSI systems and other material handling equipment, and Bulk Conveyor Services, Inc. (together, “Bulk Conveyor”). This acquisition provided us with the capacity, experience and resources to provide customers with additional solutions for emissions compliance and the addition of Bulk Conveyor’s manufacturing facility also allowed us to expand our capacity for supplying ACI systems. Currently BCSI is executing a large fleet utility contract for several DSI systems for SO₃ control and has several outstanding proposals for additional systems.

Since 2005, we have completed or are in the process of executing awarded projects for approximately 80 ACI systems intended to control mercury emissions from approximately 90 coal-fired EGU boilers. The ACI and DSI capital equipment we provide for the larger utility coal-boilers generally ranges from approximately $600,000 to $2 million per coal-fired boiler unit and in total we expect the MATS rule to create a market in excess of $1 billion for the combination of ACI and DSI systems. DSI systems, which sell at approximately $1.5 million to $3 million for an average size EGU, provide a low CAPEX alternative to scrubbers for meeting certain provisions of the MATS. The EPA predicts that about 200 DSI systems will be sold by 2015.

Since the MATS market commenced in 2011, ADA has won or received letters of intent to award contracts currently valued at approximately $75 million for ACI and DSI systems, with most of these systems scheduled to be delivered by the end of 2014. There has been indication that some generators have obtained extensions for MATS compliance, which could result in the consummation of these sales being delayed for an additional one to two years. As an indication of progress in the development of this market, the Company is in discussion on or submitting bids on approximately $180 million of ACI and DSI systems.

Mercury Control Additives

Another ADA mercury-only coal treatment technology (formerly referred to as Enhanced Coal) is in the initial stages of being marketed by the Company as M-Prove^™ to meet mercury requirements currently existing in 19 states and the MATS requirements set to go into effect in 2015. Since 2004, we have been working with Arch Coal to explore certain unique characteristics of some types of coals mined by Arch Coal that allow the coal to be burned with lower mercury emissions. We believe that a technical breakthrough that involves the application of proprietary chemicals to Western coals such as PRB reduces emissions of mercury when this pre-combustion additive is burned at power plants. We believe M-Prove may provide a benefit to the customer of up to $4 per ton of coal burned when used on Western coals, of which U.S. power plants burn up to 600 million tons per year.

We provide M-Prove through two channels – (1) through Arch Coal for use on PRB coal at the mine and (2) through direct coal treatment applied on-site at power plants. In June 2010, we entered into a Development and License Agreement (the “License Agreement”) with Arch Coal giving them an exclusive, non-transferable license to use certain technology through the application of

ADA’s proprietary pre-combustion additive to Arch Coal’s PRB mined coal. We expect that use of M-Prove will help utilities meet the mercury emissions requirements in the MATS. Pursuant to the License Agreement, we are providing development services to Arch Coal aimed at applying M-Prove to PRB coal. In addition, if we develop improvements to M-Prove that are related to the reduction of certain emissions from the burning of PRB coal, that improvement will either be included in the license at no additional cost, or, under certain circumstances, we will negotiate with Arch Coal to determine if Arch Coal wants to use the additional improvements. We retain all right, title and interest, including all intellectual property rights, in and to any technology we license to Arch Coal. The initial demonstration of coal treated at the mine and shipped by rail to a power plant produced promising results, and we have completed several additional demonstrations of M-Prove at specific power plants.

Pursuant to the License Agreement we license to Arch Coal certain technology to produce this treated coal, and we also provide Arch Coal with development services aimed at applying the technology to PRB coal. In consideration for this development work and the license provided under the License Agreement, Arch Coal paid us an initial, non-refundable license and development fee in cash totaling $2 million in June 2010 which was recognized as revenue in 2010 and 2011. Under the License Agreement, we are entitled to royalties of as much as $1 per ton of a portion of the premium for the treated coal sold by Arch Coal, depending upon the premium Arch Coal is able to charge on sales of such coal. Any royalty ultimately payable under the License Agreement will first be subject to credit to Arch Coal of an amount equal to the initial license fee, other development and operational costs paid by Arch Coal plus a rate of return on such payments.

Subsequent to entering into the License Agreement, on November 1, 2012, we entered into a related Supply Agreement under which Arch Coal will purchase the additives used in conjunction with the technology licensed under the License Agreement exclusively from us, and we will supply Arch Coal with the additives it needs. For customers that prefer to have the coal treatment applied on-site at their plants, the Company will provide the technology directly to the power plants.

The MATS will likely create a market for chemicals to be used for the reduction in mercury emissions for much of the 600 million tons of western coals burned annually. One of the advantages of the chemical used in M-Prove is that it does not use bromine which is the basis of many other competing chemical additive technologies. The power industry is beginning to experience corrosion issues in their plants that they attribute to bromine that was used to enhance the capture of mercury. Thus, we have found the industry open to considering a new technology that could help avoid what could be very expensive repairs on the plants. In October of 2012 we were awarded the first of what we believe will be a family of patents designed to protect M-Prove both in the U.S. and abroad.

Flue Gas Chemicals and Services

We have developed and deployed technologies for conditioning flue gas streams from coal-fired combustion sources that allow existing air pollution control devices such as electrostatic precipitators (“ESPs”) to operate more efficiently. Through various suppliers and contractors, we manufacture engineered units for each individual application. The units mix, pump and monitor the feed of proprietary chemical blends. The chemical blends are applied to the flue gas streams by a pressurized system of specially designed lances and nozzles. Such treatment of the flue gas stream allows for more effective collection of fly ash particles that would otherwise escape into the atmosphere and may aid in the control of mercury emissions using ACI equipment and help existing ESPs continue to operate effectively when applying other chemicals such as hydrated lime (DSI systems) exclusively or in combination with activated carbon products.

Other Consulting Services

We also offer consulting services to assist electric power generators and others in planning and implementing strategies to meet the new and increasing government emission standards requiring reductions in SO₂, NO_x, particulates, acid gases and mercury. This includes demonstrations of our commercial products. We often receive funding for consulting and a portion of our development and testing activities from industry partners that have a strategic interest in the technology.

CO₂ Capture

In addition to our two key growth areas, RC and EC, we continue to demonstrate our position as a premier developer of innovative clean energy technologies. We expect that CO₂ capture technologies will be required to control CO₂ emissions from coal-fired power plants in the future. We see this as an opportunity and continue to develop technologies to address the long-term needs of our customers to reduce CO₂ from their existing and new plants.

In 2010 we began the first field tests of our CO₂ control technology on a $3.8 million program co-funded by the DOE, as well as several major utility companies. The initial results at a plant confirmed the promising performance we had demonstrated in our laboratory. The pilot plant was moved to another plant for additional testing.

In October 2010, we began work on a second major CO₂ project, which is expected to run for a total of 51 months to develop a full-scale conceptual design and validate the design at the pilot-scale, which is a key step in the technology development process. We are the prime contractor for the approximately $20.5 million project (including expected contributions by other industry partners) administered by the DOE’s National Energy Technology Laboratory which is providing $15 million of the funding. The project provides funding to advance our commercialization plan for regenerable solid-sorbent technology.

In June 2012, we initiated the fabrication and construction phase for the pilot plant which will treat a slipstream of flue gas equivalent to that generated from producing one-megawatt of electricity. We anticipate that DOE funded CO₂ programs will continue to represent an important component of the revenue stream of the Company over the next several years. We are considering different potential future commercial markets for carbon capture technology including producing CO₂ for use in enhanced oil recovery. This technology appears to offer potential cost and energy advantages over competing liquid-solvent-based technologies.

Results of Operations – 1st Quarter 2013 versus 1st Quarter 2012

The following discussion should be read in conjunction with our unaudited consolidated financial statements and related notes thereto included elsewhere in this Form 10-Q.

Revenues totaled $68.3 million for the quarter ended March 31, 2013 versus $18.2 million for the same period in 2012, representing an increase of 275%. Our RC segment revenue increased primarily due to the increased rental income from RC facilities we leased or sold to third parties and increased RC sales from other facilities that were operated by Clean Coal prior to being leased or sold to third parties. The increase is also due to a 217% increase in our EC segment revenues. We expect overall revenues and costs for 2013 to be somewhat lower than for 2012 given our plans to sell or lease additional RC facilities including one currently being operated by Clean Coal for its own account which is expected to reduce RC sales and raw coal costs.

Cost of revenues for the quarter ended March 31, 2013 increased by $44.4 million from $14.2 million to $58.6 million from the same period in 2012 primarily as a result of costs of coal purchased for operations by Clean Coal and operating costs related to RC facilities operated by Clean Coal during the quarter. In addition, costs increased by 202% from $2.1 million to $6.3 million in the EC segment due to the increased activity on contracts awarded for ACI and DSI systems in the fourth quarter of 2012 and first quarter of 2013.

Gross margins were 14.3% for the quarter ended March 31, 2013 compared to 22% for the quarter ended March 31, 2012. The decrease primarily reflects such increased costs. If the RC sales and raw coal purchases of $45 million and operating costs of $6.5 million related to RC produced for Clean Coal’s account, which will not continue with respect to any facilities after they are leased or sold, are subtracted from the revenue and costs of revenue amounts reported for the first quarter of 2013, adjusted gross margin would have been 70% for the first quarter of 2013 compared to a similarly adjusted gross margin of 76% for the first quarter of 2012. The revenues and cost of revenues for the first quarter of 2012 included RC sales and raw coal purchases of $9.8 million and operating costs of $2.4 million related to RC produced for Clean Coal’s account. Adjusted gross profit margin percentage is a non-GAAP financial measure which is used to provide investors with greater transparency with respect to the effect on gross margin from Clean Coal’s operation of certain RC facilities for its own account. We believe this non-GAAP financial measure provides meaningful supplemental information for investors regarding the performance of our business and the effect on gross margin of the operation of these RC facilities by Clean Coal for its own account.

For the near term, we expect the lease and sale of RC facilities to represent an increasing source of revenues, for which the anticipated gross margins are higher than our EC and CC segments. As a result, we expect the gross margin for fiscal year 2013 to be higher than the overall margin realized in 2012.

Refined Coal

Revenues in our RC segment totaled $58.1 million for the quarter ended March 31, 2013 compared to $15.2 million for the quarter ended March 31, 2012, representing an increase of 283%. Rental income from the leased and sold RC facilities totaled $12.2 million in the first quarter of 2013 compared to $5.4 million for the same period in 2012. RC coal sales totaled $45 million for the quarter ended March 31, 2013 compared to $9.8 million for the same period in 2012.

Clean Coal incurs the operating costs for the RC facilities operated for its own account and retains for its owners the tax credits generated from the approximately 2 million tons produced for its own account during the first quarter of 2013 compared to 268,000 tons during the first quarter of 2012. We expect our quarterly revenues to continue to fluctuate based on seasonal variations in electricity demand as well as planned and unplanned outages required by the power plants for equipment repair and maintenance. On an ongoing basis, we expect the five RC facilities leased or sold third party investors to generate approximately $50 million to $60 million in revenue per year now through 2021.

Cost of revenues for the RC segment increased by $39.4 million or 327% for the quarter ended March 31, 2013 compared to the same period in 2012. Costs increased due primarily to the cost of coal acquired to operate RC facilities which cost approximates the revenues realized on its sale as noted above. We expect future RC margins for the RC facilities leased or sold to others to be at a level near 95%.

RC segment profits increased by $4.3 million or 238% for the quarter ended March 31, 2013 compared to the same period in 2012 primarily as a result of the additional RC facilities leased and sold during 2013, offset by the costs of operating certain RC facilities for our own account and one-time transactional costs incurred as we continue to work through moving the placed-in-service facilities to full-time, long-term operations. These amounts are prior to the allocation of such profits to the non-controlling interests of Clean Coal.

Emission Control

Revenues in our EC segment totaled $8.8 million for the quarter ended March 31, 2013 compared to $2.8 million for the same period in 2012, representing an increase of 217%, primarily due to increased sales of ACI and DSI systems and the recognition of revenues for previously awarded sales contracts as well as revenues resulting from our acquisition of the assets of Bulk Conveyor. Revenues from the EC segment for the quarter ended March 31, 2013 were comprised of sales of ACI and DSI systems and services (86%), consulting and demonstration services (11%) and flue gas chemicals and services (3%) compared to 51%, 41%, and 8%, respectively, for the same period in 2012. We expect our EC segment revenues related to ACI and DSI systems to continue to grow significantly in 2013 as we expect utilities, cement plants and industrial boilers to continue placing orders in response to the MATS and other MACT regulations. We expect our gross margin percentage for our EC segment for 2013 will approximate 20% to 25%.

Our consulting revenues totaled $1 million for the quarter ended March 31, 2013 compared to $1.1 million for the same period in 2012. We are continuing with demonstrations and other work related to the MATS and we expect our consulting revenue to continue to be a significant part of EC revenues during 2013 as several customers are seeking alternatives on how best to comply with the MATS.

As of March 31, 2013, we had contracts in progress for work related to our EC segment totaling approximately $32.7 million, which we expect to recognize as revenue in 2013 and 2014. Our ACI and DSI systems revenues totaled $7.5 million for the quarter ended March 31, 2013, representing an increase of 433% compared to the same period in 2012, primarily due to increased sales of ACI and DSI systems and the recognition of revenues on previously awarded sales contracts as well as revenues resulting from our acquisition of the assets of Bulk Conveyor as discussed above.

Cost of revenues for the EC segment increased by $4.2 million for the first quarter of 2013 compared to the same period in 2012, primarily as a result of the increased revenue-generating activities from our ACI and DSI system sales. Gross margin for the EC segment was 29% for the first quarter of 2013 compared to 25% for the same period in 2012.

EC segment profits increased by $1.5 million for the quarter ended March 31, 2013 compared to the same period in 2012. The increase was primarily a result of higher margins on recent contract awards and a reduction in overhead costs from 2012.

CO₂ Capture

Revenues in our CC segment totaled $1.4 million for the quarter ended March 31, 2013, representing an increase of 404% from the same period in 2012, primarily due to the billing milestones for these projects. We had outstanding DOE contracts, including anticipated industry cost share in progress totaling $11.3 million as of March 31, 2013. We expect to recognize approximately $8.3 million from these contracts during the remainder of 2013 if the anticipated schedule of activities is maintained. We are seeking additional cost share participants for the remaining work under the contracts.

Cost of revenues for the CC segment increased by $731,000 or 625% for the quarter ended March 31, 2013, primarily related to the increase in work being performed under these projects. Gross margin for this segment was 40% for the quarter ended March 31, 2013 compared to 59% for the same period in 2012. The Company records its estimated cost share portion of the DOE contracts as research and development (“R&D”) expense. The margin amounts shown are net of that allocation to R&D expense. The decrease in gross margin from 2013 to 2012 is due primarily to the increase in the use of subcontractors and purchasing of equipment, both of which typically have lower cost mark-ups than our internal labor under these contracts. Lower cost share participation from third parties also contributed to higher costs and lower margins. We expect the overall gross margin for the CC segment for fiscal year 2013 to be lower than the levels achieved in 2012, due to our likely share of costs and the mixture of direct costs (labor versus equipment and subcontractors) and indirect costs associated with this segment.

CC segment profits decreased by $142,000 to a loss of $80,000 for the quarter ended March 31, 2013 compared to the same period in 2012. The decrease was primarily the result of no cost share participation by others so far this year and greater use of subcontractors and purchasing of equipment for construction of the pilot-scale technology validation unit required to further develop our CO₂ capture technology.

Our contracts with the government are subject to audit by the federal government, which could result in adjustments to previously recognized revenue. Our historical experience with these audits has not resulted in significant adverse adjustments to amounts previously received; however the audits for the years 2005 and later have not been finalized. Revenues recognized from 2005 through 2012 that are subject to government audit totaled approximately $31 million. In addition, we had $11.3 million of remaining unearned amounts under contracts subject to audit as of March 31, 2013. We believe, however, that we have complied with all requirements of the contracts and future adjustments, if any, will likely not be material. In addition, the federal government must appropriate funds on an annual basis to support DOE contracts, and funding is always subject to unknown and uncontrollable contingencies.

Other Items

General and administrative expenses increased by $3.7 million or 101% to approximately $7.3 million for the quarter ended March 31, 2013 compared to the same period in 2012. The increase from first quarter of 2012 is primarily due to increased compensation due to our increased sales, marketing, bid and proposal staff and activities, increased occupancy cost from our expanded space, the addition of activities of BCSI and increased overhead and transactional costs of Clean Coal.

We incur R&D expenses not only on direct activities we conduct but also by sharing a portion of the costs in the government and industry programs in which we participate. Total R&D expense increased by $139,000 or 25% for the quarter ended March 31, 2013 compared to the same period in 2012 as a result of increases in EC and RC activities. The increase in total R&D is related to preparing for growth in the delivery of our ACI and DSI systems, as well as our RC activities. We had no significant cost share for R&D under DOE related contracts so far in 2013 or for the same period in 2012. Future consolidated research and development expenses, except for those anticipated to be funded by the DOE contracts and others that may be awarded, are expected to be higher in 2013 compared to 2012. We continue to anticipate that our future R&D expenses will grow in direct proportion to DOE funded CO₂ work we perform for the next several years and other technology development we choose to pursue.

We had other income including interest of $70,000 for the quarter ended March 31, 2013 compared to $99,000 for the same period in 2012. We recognized $673,000 in expenses related to royalty payments to Norit Americas, Inc. and Norit International N.V. f/k/a Norit N.V. (“Norit”) for the quarter ended March 31, 2013 and $284,000 for the same period in 2012. We expect that these royalty payments to Norit will amount to between approximately $2 million and $4 million per year for the near future. We had interest expense of $383,000 for the quarter ended March 31, 2013 compared to $470,000 for the same period in 2012. The expense in 2013 is related to interest paid on the deposit repayment made to GS RC and due to the deferred gain resulting from Clean Coal’s tax treatment of leased and sold RC facilities. The 2012 amount is related to the line of credit agreements and the deferred gain resulting from Clean Coal’s tax treatment of leased RC facilities.

The net operating loss from continuing operations before income tax benefit and non-controlling interest was $357,000 for the quarter ended March 31, 2013 compared to $1.9 million for the same period in 2012. The decrease in the net operating loss in 2013 is due in large part to the increase in activity in all three of our segments.

Liquidity and Capital Resources

Working Capital

Our principal sources of liquidity are cash on hand and our cash flows from RC activities and other operations. We had consolidated cash and cash equivalents totaling $21.9 million at March 31, 2013 compared to consolidated cash and cash equivalents of $9.7 million at December 31, 2012.

At March 31, 2013, we had a working capital deficit of $11 million compared to a working capital deficit of $24.1 million at December 31, 2012. The decrease in deficit was in part due to an increase in cash and cash equivalents from the the sale of the fifth RC facility and the elimination of the outstanding balance on Clean Coal’s line of credit. In addition, included in the March 31, 2013 amount are $16.5 million in deposits from GSFS on RC facilities and $16.6 million in deferred revenues which will not require the use of cash but will generate revenue when amounts are earned. The deposit amount from 2012 decreased $4.7 million as discussed below.

If GSFS determines that it will not lease an RC facility after it has paid the deposit, it can provide notice requesting the return of the deposit paid for that RC facility, and the deposit must be paid within 30 days of the end of the quarter in which the notice is given. In October 2012, GSFS determined that it would not pursue leases on two particular RC facilities on which it had paid deposits totaling $4.7 million and concurrently gave notice for the return of related deposits. In December 2012, GSFS agreed to defer the return of these deposits until April 30, 2013. In March 2013, Clean Coal returned the $4.7 million in deposits plus accrued interest to GSFS.

On February 28, 2013, Clean Coal sold an RC facility to a new third party investor. The terms of the sale included $20 million paid immediately to Clean Coal and a combination of fixed and variable payments going forward. An additional $5 million is to be paid to Clean Coal when the buyer receives an applied for PLR from the IRS, which is expected later this year.

Our ability to generate the financial liquidity required to meet ongoing operational needs and to meet our obligations will likely depend upon our ability to maintain a significant share of the market for mercury control equipment, the continued operation of the RC facilities leased or sold to third parties to date, success in the sale or lease of additional RC facilities to third party investors and our ability to raise additional financing. We believe, with the lease of four RC facilities to date, and the sale of the fifth RC facility, that we have sufficient sources of working capital to meet the operational needs of the Company for the next 12 months. If GSFS requires the return of its remaining deposits or does not place deposits on additional RC facilities, we may need to seek additional sources of financing to meet those obligations if they became immediately due and payable and/or decide to suspend operations at one or more of the RC facilities that Clean Coal is operating for its own account.

We have recorded long-term liabilities of $2.5 million related to litigation settlement obligations, $2.2 million in notes payable related to the acquisition of Bulk Conveyor’s assets and $14.3 for accrued warranty, deferred revenue and other liabilities as of March 31, 2013. Our stockholders’ deficit was $39.8 million as of March 31, 2013 compared to $40.1 million as of December 31, 2012. The decrease in stockholders’ deficit is due to the net loss and is offset by the net income from the non-controlling interest for 2013.

Clean Coal Related Items

Clean Coal, our joint venture with NexGen, placed two RC facilities into service in 2010 (which were exchanged for two newly constructed, redesigned RC facilities in November and December 2011), which are leased to a third party. In 2012, two additional RC facilities were leased, one to the lessee of the first two facilities and one to a new third party investor. In addition, in February 2013, a fifth RC facility was sold which Clean Coal had been previously operating for its own account. On an ongoing basis, we expect our five currently leased and sold RC facilities to generate from $50 million to $60 million in revenue per year from now through 2021 based on their operations and periodic payments we expect to receive. We expect by the end of 2013 to have additional RC facilities under lease or sold such that total revenues from these activities will be at a run-rate of over $100 million per year and be at a level of producing pre-tax cash flows of as much as $50 million per year. We would expect those levels to continue through 2021, the present term of the Section 45 tax credit, with an opportunity to double those amounts by the end of 2014 as we look to have all of our RC facilities operating on a continuous basis and leased or sold by that time. We believe that once most of the RC facilities are leased or sold to others and become fully operational, they will achieve an annualized segment rental revenue rate of approximately $200 million; excluding the approximately $250 million to $300 million in ongoing coal sales and raw coal purchases from RC facilities that Clean Coal is expected to operate in the long-term for its own account. These revenue rates would be expected to generate approximately $100 million in segment income to the Company after payments to minority partners, including an estimated $30 million in tax credits apportioned to the Company to be generated by RC facilities operated by Clean Coal.

Other Liquidity and Capital Resource Items

Our trade receivables balance is comprised of both amounts billed to customers as well as unbilled revenues that have been recognized. As of March 31, 2013 our trade receivables balance was $15.7 million compared to $11 million at December 31, 2012. Our trade receivables balance was higher at March 31, 2013 compared to December 31, 2012 primarily due to the nature and timing of our progress on contracts as impacted by our billing milestones for our increased ACI and DSI systems contracts.

Under our defined contribution and 401(k) retirement plan, we match up to 7% of limited salary amounts deferred by employees in the Plan. During the quarter ended March 31, 2013, we recognized $113,000 of matching expense which payment was made with our stock. Our matching expense is expected to amount to $475,000 for 2013 depending on employee participation in the plan.

We had net current deferred tax assets of $2.3 million and long-term deferred tax assets of $37.8 million as of March 31, 2013 compared to net current deferred tax assets of $2.3 million and long-term deferred tax assets of $37.2 million as of December 31, 2012. The current period tax rate used to calculate deferred income taxes reflects our estimate of our full-year tax rate. We believe that our effective tax rate may vary significantly quarter to quarter as actual earnings or losses are realized and tax credits are generated. The current and long-term amounts for both periods have been reduced to zero by recording a valuation allowance as discussed in Note 11 to the consolidated financial statements. Management determined that it was necessary to record the valuation allowance against the Company’s deferred tax assets after reconsidering the weight given in the original assessment to the relevant information used to measure the positive and negative evidence regarding the potential for ultimate realization of the net deferred tax assets.

Cash flows provided by operations totaled $17.1 million for the quarter ended March 31, 2013 compared to cash flows used in operations of $9.2 million for the same period in 2012. The increase in operating cash flows primarily resulted from increases in deferred revenues and other liabilities of $23.1 million, accounts receivable of $4.6 million and accounts payable of $1.5 million, and was offset by a decrease in deposits of $4.7 million. These changes in our operating assets and liabilities correspond to the facility leasing and sale activities and the nature and timing of our procurement and billing cycle and development activities. In addition, adjustments related to non-cash operating activities included expenses paid with stock and restricted stock of $635,000, depreciation and amortization of $1.4 million and non-controlling interest in Clean Coal of $1.8 million, each of which increased our cash flow from operations.

Net cash used in investing activities was $1.8 million for the quarter ended March 31, 2013 compared to $5.9 million for the same period in 2012. The cash used consisted primarily of purchases of equipment, leasehold improvements and certificates of deposit.

Cash used in financing activities was $3.1 million for the quarter ended March 31, 2013 compared to $2.5 million used in financing activities for the same period in 2012. The cash used consisted of net payments on Clean Coal’s line of credit of $3 million and payments on notes payable of $138,000.

Critical Accounting Policies and Estimates

Revenue Recognition – We follow the percentage of completion method of accounting for all significant contracts excluding RC leases, government contracts, coal and chemical sales and technology license royalties. The percentage of completion method of reporting income takes into account the estimated costs to complete and estimated gross margin for contracts in progress. RC base rents, which are fixed, are recognized over the life of the lease. RC contingent rents are recognized as they are earned. We recognize revenue on government contracts generally based on the time and expenses incurred to date. Royalties from technology licenses are recognized when earned.

Significant estimates are used in preparation of our financial statements and include:

•

our warranty costs;

•

our percentage of completion method of accounting for significant long-term contracts, which is based on estimates of gross margins and of the costs to complete such contracts;

•

the period over which we estimate we will earn up-front license payments; and

•

estimated future royalty obligations associated with our settlement with Norit.

In addition, amounts invoiced for government contracts are subject to change based on the results of future audits by the federal government. We have not experienced significant adjustments in the past, and we do not expect significant adjustments will be required in the future. We also use our judgment to support the current fair value of goodwill and other intangible assets of $3.8 million in our consolidated balance sheets. Management believes the value of other recorded intangibles is not impaired, although market demand for our products and services could change in the future, which would require a write-down in recorded values. As with all estimates, the amounts described above are subject to change as additional information becomes available, although we are not aware of anything that would cause us to believe that any material changes will be required in the near term.

Under certain contracts we may grant performance guaranties or equipment warranties for a specified period and the achievement of certain plant operating conditions. In the event the equipment fails to perform as specified, we are obligated to correct or replace the equipment. Estimated warranty costs are recorded at the time of sale based on current industry factors. The amount of the warranty liability accrued reflects our best estimate of expected future costs of honoring our obligations under the warranty section of each contract. We believe the accounting estimate related to warranty costs is a critical accounting estimate because changes in it can materially affect net income, it requires us to forecast the amount of equipment that might fail to perform in the future, and it requires a large degree of judgment.

Income taxes are accounted for under the asset and liability approach. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. At each reporting date, management reviews deferred tax assets and liabilities and any related valuation allowance and, if necessary, revises them to reflect changed circumstances. In a situation where recent losses have been incurred, the accounting standards require convincing evidence that there will be sufficient future taxable income to realize deferred tax assets. Deferred tax assets have been reduced to zero by a valuation allowance because, in the opinion of management, it is more likely than not that all of the deferred tax assets will not be realized. A change in laws can have a material effect on the amount of income tax we are subject to. We are not aware of anything that would cause us to believe that any material changes will be required in the near term.

We recognize all share-based payments, including grants of stock options, restricted stock units and employee stock purchase rights in our financial statements based upon their respective grant date fair values. Under this standard, the fair value of each employee stock option and employee stock purchase right is estimated on the date of grant using an option pricing model that meets certain requirements. We currently use the Black-Scholes option pricing model to estimate the fair value of our stock options and stock purchase rights. The Black-Scholes model meets the requirements of FASB Topic 718 but the fair values generated by the model may not be indicative of the actual fair values of our equity awards, as it does not consider certain factors important to those awards to employees, such as continued employment and periodic vesting requirements. The determination of the fair value of share-based payment awards utilizing the Black-Scholes model is affected by our stock price and a number of assumptions, including expected volatility, expected life and risk-free interest rate. We use a historical volatility rate on our stock options. The fair value of our restricted stock is based on the closing market price of our Common Stock on the date of grant. If there are any modifications or cancellations of the underlying securities, we may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. To the extent that we grant additional equity securities to employees or we assume unvested securities in connection with any acquisitions, our stock-based compensation expense will be increased by the additional unearned compensation resulting from those additional grants or acquisitions.

Consolidation of Subsidiaries –Since inception, ADA has been considered the primary economic beneficiary of the joint venture with Clean Coal and, therefore, we have consolidated its accounts with ours.

We hold a 50% interest in CCSS. However, we control only two of the five seats on the board of managers and our equity partner controls the other three seats. Therefore, we believe our 50% interest does not constitute control of CCSS and we have recorded our interest under the equity method.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of March 31, 2013.

Item 4. Controls and Procedures

We are required to maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Management necessarily applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding management’s control objectives.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation and under supervision of our Chief Executive Officer and Chief Financial Officer, has reviewed and evaluated the effectiveness of the Company’s disclosure controls and procedures as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) and 15d-15(e), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on their review and evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are adequate and effective to ensure that material information related to our financial statements are made known to them by others in a timely manner, particularly during the period in which this quarterly report on Form 10-Q was being prepared, and that no changes are required at this time.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the most recently completed fiscal quarter that have materially affected, or are likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

During the quarter ended March 31, 2013, we issued 6,285 unregistered shares of our common stock under our Amended and Restated 2007 Equity Incentive Plan (the “2007 Plan”), which was originally adopted by our Board of Directors on April 27, 2007 and approved by our shareholders on June 19, 2007. The 2007 Plan was amended and restated by our Board of Directors to make non-material changes on August 31, 2010 and amended pursuant to Amendment No. 1 and approved by our Board of Directors on January 25, 2011. The 2007 Plan was re-approved by our Board of Directors on February 24, 2012 and approved by our shareholders on July 19, 2012. Such shares were issued to the following affiliated companies in the following amounts on January 18, 2013 as fees for their service on the Board of Directors of the Company:


Director	Shares
Robert Shanklin (shares issued to Arch Coal, Inc.)		1,964
Robert Caruso (shares issued to B/3 Management Resources, LLC)		2,357
