EXPLANATORY NOTE

ADA-ES, Inc. (the “Company”) is filing this Amendment No. 2 on Form 10-Q/A (this “Amendment”) to amend its Quarterly Report on Form 10-Q for the three and six months ended June 30, 2011 originally filed with the Securities and Exchange Commission (the “SEC”) on August 12, 2011 (the “Original Filing”) and subsequently amended on September 28, 2011. This Amendment reflects the restatement of the Company’s consolidated financial statements and amendment of related disclosures as of June 30, 2011 and December 31, 2010 and for the three and six month periods ended June 30, 2011 as discussed below and in Note 13 to the accompanying restated consolidated financial statements.

1. Background of the Restatement

As discussed in the Company’s Current Reports on Form 8-K dated June 20, 2012 and August 14, 2012, the Company’s management determined, after consultation with the Company’s Board of Directors, Audit Committee, independent registered public accounting firm and outside tax experts, that the Company’s previously issued audited consolidated financial statements included in its Annual Reports on Form 10-K for the fiscal years ended December 31, 2010 and 2011 and the interim unaudited consolidated financial statements included in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2011, June 30, 2011, September 30, 2011, March 31, 2012 and June 30, 2012 needed to be restated as a result of certain corrections to the figures and disclosures contained therein and therefore could no longer be relied upon.

Reclassification of Equity Interest

The Company had previously classified the equity interest of an affiliate of the Goldman Sachs Group (“GS”) in our joint venture, Clean Coal Solutions, LLC (“Clean Coal”), as a non-controlling interest in stockholders’ equity (deficit) on the Company’s Consolidated Balance Sheet as of June 30, 2011, September 30, 2011, December 31, 2011 and March 31, 2012. In June 2012, after completion of a review and evaluation of the operating agreement of Clean Coal and the members’ rights and obligations thereof and applicable accounting authoritative literature, management determined that the GS interest would be more appropriately classified as temporary equity as of June 30, 2011 and for each subsequent quarter thereafter because of a provision in the Clean Coal operating agreement that permits GS to require redemption of its interest under certain limited circumstances. As a result, the Company is restating its consolidated financial statements for the quarterly period ended June 30, 2011 to reflect the GS interest as temporary equity on the its consolidated balance sheet.

Deferred Tax Assets Valuation Allowance

In August 2012, after extensive discussions with the SEC’s Division of Corporation Finance and Office of the Chief Accountant and the Company’s outside tax experts, independent registered public accounting firm, Audit Committee and Board of Directors, management determined that the Company should have recognized a full valuation allowance against its net deferred tax assets as of December 31, 2010 and for each subsequent quarter thereafter. 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 deferred tax assets.

Realization of the deferred tax assets is dependent upon the Company’s ability to generate future taxable income. In its reassessment, management concluded that the objective and verifiable negative evidence represented by historical losses outweighed more subjective positive evidence of anticipated future income. As a result, management determined that it was necessary to record a full valuation allowance against the Company’s deferred tax assets and is restating the consolidated financial statements for the quarterly period ended June 30, 2011 and as of December 31, 2010.

2. Impact on the Consolidated Financial Statements

The financial statement effect of these changes on the Company’s Consolidated Balance Sheets as of June 30, 2011 and December 31, 2010, Consolidated Statement of Operations for the three and six months ended June 30, 2011, Consolidated Statement of Changes in Stockholders’ Equity (Deficit) for the six months ended June 30, 2011 and Consolidated Statement of Cash Flows for the six months ended June 30, 2011 is discussed in Note 13 in the accompanying consolidated financial statements. The restatement reflects non-cash adjustments and has no effect on previously reported operating income results. The Company also amended its Annual Report on Form 10-K for the fiscal year ended December 31, 2010 on October 19, 2012.

3. Internal Control over Financial Reporting and Disclosure Controls and Procedures Considerations

Management has concluded that material weaknesses in the Company’s internal control over financial reporting existed related to the accounting for the equity investment in Clean Coal that has been held by an affiliate of GS since May 2011 and the establishment and maintenance of a valuation allowance against the Company’s deferred tax assets. Accordingly, this Amendment amends the Company’s disclosures regarding the effectiveness of the Company’s internal control over financial reporting and disclosure controls and procedures as of June 30, 2011.

4. Amended Items

No attempt has been made in this Amendment to modify or update the disclosures in the Original Filing except as required to reflect the effect of the restatement discussed herein. Except as otherwise noted herein, this Amendment continues to describe conditions as of the date of the Original Filing and the disclosures contained herein have not been updated to reflect events, results or developments that occurred after the date of the Original Filing, or to modify or update those disclosures affected by subsequent events. Among other things, forward-looking statements made in the Original Filing have not been revised to reflect events, results or developments that occurred or facts that became known to us after the date of the Original Filing, other than the restatement, and such forward-looking statements should be read in conjunction with our filings with the SEC subsequent to the filing of the Original Filing. Accordingly, this Amendment should be read in conjunction with the Original Filing and the Company’s other filings with the SEC.

Part I—Item 1 (Consolidated Financial Statements), Part I—Item 2 (Management’s Discussion and Analysis of Financial Condition and Results of Operations) and Part I—Item 4 (Controls and Procedures) have been amended from the Original Filing as a result of the restatement. Part II—Item 6 (Exhibits) has also been amended to, among other things, include currently dated certifications from the Company’s principal executive officer and principal financial officer as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002. The certifications of the Company’s principal executive officer and principal financial officer are attached to this Amendment as Exhibits 31.1, 31.2, 32.1 and 32.2.

Basis of Presentation

ADA-ES, Inc. (“ADA”), its wholly-owned subsidiary, ADA Environmental Solutions, LLC (“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 Activated Carbon Injection (“ACI”) systems, contracts co-funded by the government and industry and development and lease of equipment for the refined coal (“RC”) market. The Company’s sales occur principally throughout the United States.

The consolidated balance sheet as of December 31, 2010, which has been derived from restated audited financial statements, and 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 and, therefore, 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, ADA LLC and Clean Coal. We have eliminated all significant intercompany balances and transactions 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 three and six months ended June 30, 2011 are not necessarily indicative of the results that may be expected for the year ending December 31, 2011.

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/A for the year ended December 31, 2010, as amended and restated. The accounting policies used in preparing these consolidated financial statements are the same as those described in our Form 10-K and its amendments. The financial information included in these Notes relating to the Company’s financial position as of June 30, 2011 and December 31, 2010, and results of operations for the three and six months ended June 30, 2011 have been restated to give effect to the accounting adjustments discussed in Note 13.

The Company prepares its consolidated financial statements in conformity with U.S. generally accepted accounting principles. The preparation of these financial statements requires us 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.

Investments in Unconsolidated Entities

ADA Carbon Solutions, LLC

On October 1, 2008, the Company entered into a Joint Development Agreement (“JDA”), a Limited Liability Company Agreement (“LLC Agreement”), and other related agreements with Energy Capital Partners I, LP and its affiliated funds (“ECP”) and formed the joint venture known as ADA Carbon Solutions, LLC (“Carbon Solutions”) for the purposes of funding and constructing an activated carbon (“AC”) manufacturing facility in Red River Parish, Louisiana and similar projects. Carbon Solutions is principally engaged in development activities related to its AC business and selling of AC from its manufacturing facility (the “AC Facility”). Among Carbon Solutions’ various wholly-owned subsidiaries are ADA Carbon Solutions (Red River), LLC (“Red River”) and Crowfoot Supply Company, LLC (“Crowfoot Supply”).

Under the JDA and the LLC Agreement, the Company transferred the development assets and certain liabilities relating to the production, processing and supply of AC to ADA’s then wholly-owned subsidiaries Red River, Morton Environmental Products, LLC, Underwood Environmental Products, LLC and Crowfoot Supply and subsequently transferred the equity in these subsidiaries and certain contracts, goodwill and intellectual property relating to the AC supply business to Carbon Solutions as its $18.4 million initial contribution.

As of June 30, 2011, ADA owns a 22.8% interest in Carbon Solutions and ADA’s net investment of $9.8 million is being accounted for under the equity method of accounting. Accordingly, the respective share of approximately $1.8 million and $3.8 million of Carbon Solutions’ net loss for the three and six months ended June 30, 2011, respectively, has been recognized in the consolidated statements of operations and ADA’s investment in Carbon Solutions has been reduced by its respective share of such loss.

Under the terms of the JDA, the Company is required to indemnify ECP and Carbon Solutions for certain damages and expenses they have incurred with respect to the Company’s litigation with Norit Americas, Inc. (“Norit”) (See Note 9). As of June 30, 2011, the Company has recorded a liability to Carbon Solutions of approximately $30.7 million related to such damages and expenses incurred by Carbon Solutions. Approximately $1.6 million of that amount relates to royalty obligations recorded as a result of the interim award and has been classified as a current liability as a component of accrued arbitration award and related liability on the accompanying consolidated balance sheets. Approximately $29.1 million has been classified as non-current liabilities and is included in accrued indemnity on the accompanying consolidated balance sheets.

Clean Coal Solutions Services

On January 20, 2010, the Company, together with NexGen Resources Corporation (“NexGen”), formed Clean Coal Solutions Services, LLC (“CCSS”) for the purpose of operating the RC facilities leased to a third party. The Company has a 50% ownership interest in CCSS (but does not control it) and the Company’s investment of approximately $501,000 as of June 30, 2011 includes its share of CCSS income since its formation and is accounted for under the equity method of accounting.

The following presents summarized unaudited information as to consolidated assets, liabilities and results of operations of CCSS. The consolidated financial statements of CCSS include the accounts of the third party which leases the RC facilities.

Joint Venture Investment in Clean Coal (restated)

In November 2006, ADA licensed its RC technology on an exclusive basis to the Clean Coal joint venture, which was formed in 2006 with NexGen, to market the RC technology. 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 monetized those facilities. The operating agreement of Clean Coal required NexGen and ADA to each pay 50% of the costs of operating Clean Coal and specified certain duties that both parties were obligated to perform.

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 an affiliate of The Goldman Sachs Group, Inc. (“GS”) (see Notes 8 and 13 for discussion regarding the classification as temporary equity of GS’s interest obtained through this transaction). GS’s interest has certain preferences over ADA and NexGen as to liquidation and profit distribution. GS has no further capital call requirements and does not have a voting interest. In conjunction with the closing of the purchase agreement, ADA, NexGen and GS entered into a Second Amended and Restated Operating Agreement and an Exclusive Right to Lease Agreement pursuant to which Clean Coal granted GS the 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 two existing facilities. As a result of the transaction, ADA owns an effective 42.5% of Clean Coal. Since its inception, ADA has been considered the primary economic beneficiary of this joint venture and has consolidated the accounts of Clean Coal.

Deferred Revenues

Deferred revenues consist of:

•

billings in excess of costs and earnings on uncompleted contracts;

•

unearned revenues on licensing of the Company’s intellectual property to Arch Coal, Inc. (“Arch”) (as discussed further below); and

•

deferred rent revenue related to Clean Coal’s lease of its RC facilities (also as discussed further below).

Arch Coal

In June 2010, the Company entered into a Development and License Agreement with Arch in which the Company licensed, on an exclusive non-transferable basis, the use of certain of its technology to enhance coal by a proprietary coal treatment process and received a non-refundable license fee of $2 million in cash. The Company expects to recognize these revenues as the technology is further evaluated and developed and Arch realizes the benefits of the technology. As part of the agreement, Arch is required to purchase from the Company the chemicals required to enhance its coal. Future revenues of approximately $667,000 are expected to be recognized during the remainder of 2011 and are included in current deferred revenues.

Clean Coal

In June 2010, Clean Coal executed agreements to lease its RC facilities. These agreements provided for, among other things, a “prepaid rent payment” of $9 million for both facilities that was received before June 30, 2010. Thus far, in 2011, the Company has recognized $10.8 million in total rent revenues related to the RC facilities which includes $1.8 million from the initial prepaid rent payment. Future revenues expected to be recognized with respect to the prepaid rent paid are included in deferred revenues for the current period and in accrued warranty and other liabilities for the long-term period, and consist of the following:

Net Income (Loss) Per Share (restated)

Basic net income (loss) per share is computed based on the weighted average common shares outstanding in the period. Diluted net income (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 six months ended June 30, 2011 and 2010, and for the three months ended June 30, 2010 were excluded from the calculation of diluted shares, as their effect is anti-dilutive.

Share Based Compensation

Since 2003, the Company has had several stock and option plans, including the Amended and Restated 2007 Equity Incentive Plan dated as of August 31, 2010 (the “2007 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”) described below. These plans allow the Company to issue stock or options for shares of common stock to employees, Board of Directors and non-employees.

Following is a table summarizing the option activity for the six months ended June 30, 2011:

		201,740	$	10.27		4.0

No options were granted and/or vested during the three or six months ended June 30, 2011.

Although the Company adopted the 2007 Plan in 2007, it was further amended and restated as of August 31, 2010 to make non-material changes to assure Internal Revenue Code Section 409A compliance and to increase the non-management director annual grant limit to 15,000 shares of common stock from 10,000 shares. The 2007 Plan authorizes the issuance to employees, directors and non-employees of up to 790,372 shares of common stock, either as restricted stock grants or to underlie options to purchase shares of the Company’s common stock. Remaining shares available for issuance under the 2007 Plan are shown below.

In 2009, the Company revised its 401(k) Plan. The revision permits the Company 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. The Company 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 the Company’s common stock on the date of issuance.

Following is a table summarizing the activity under various stock issuance plans for the six months ended June 30, 2011:

Temporary Equity (restated)

As described in Note 3, 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 GS. Approximately 15.8 units of non-voting Class B membership interests were issued to GS for $60 million in cash. ADA and NexGen each received $30 million as a result of the sale. In conjunction with the closing of the purchase agreement, ADA, NexGen and GS entered into a Second Amended and Restated Operating Agreement and ADA and NexGen each exchanged 50 units of membership interests for approximately 42.1 voting Class A units in Clean Coal (each of which represents a 50% voting interest). Since the transaction did not result in a change in control of Clean Coal, the amount received from this transaction was originally recorded to stockholders’ equity (deficit), net of the tax effect of $11 million.

The terms of the Operating Agreement permit GS to require redemption of the unreturned portion of its initial $60 million investment in Clean Coal plus a return of 15% under certain limited circumstances. In June 2012, after completion of a review and evaluation of the applicable agreement and accounting authoritative literature, management determined that GS’s interest in Clean Coal is more appropriately classified as temporary equity as a result of the provision in the agreement for possible redemption of the unreturned portion of GS’s investment plus the required return under certain limited circumstances. As a result, this transaction has been recorded as temporary equity on the restated consolidated balance sheet as of June 30, 2011. See Notes 9 and 13 for additional discussion.

(9)

Stockholders’ Equity (Deficit) (restated)

Stockholders’ equity (deficit) has been restated. The restated ADA portion of stockholders’ deficit for the period ended June 30, 2011 includes a $30 million reduction attributable to the reclassification of temporary equity as discussed in Note 8 and a $21.2 million reduction attributable to the recognition of a valuation allowance against the Company’s deferred tax assets. The restated ADA portion of stockholders’ deficit for the fiscal year ended December 31, 2010 includes a $15.7 million reduction attributable to the recognition of a valuation allowance against the Company’s deferred tax assets. See Notes 11 and 13 for additional discussion.

Non-Controlling Interest

The non-controlling interest portion of stockholders’ equity (deficit) includes such interests related to Clean Coal. As discussed in Note 8, the restated non-controlling interest portion of stockholders’ deficit for the period ended June 30, 2011 includes a $30 million reduction attributable to the reclassification of temporary equity. See Note 13 for additional discussion.

Commitments and Contingencies

Retirement Plan

The Company 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:


	Three Months Ended June 30, 2011		Six Months Ended June 30, 2011
	(In thousands)
Matching contributions in stock	$	92	$	182

Performance Guarantee on AC Injection Systems

Under certain contracts to supply ACI systems, the Company may guarantee 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 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 accompanying consolidated balance sheets. Any warranty costs paid out in the future will be charged against the accrual. The adequacy of 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:


	Three Months Ended June 30,						Six Months Ended June 30,
	2011			2010			2011			2010
	(In thousands)						(In thousands)
Beginning Balance	$	585		$	615		$	612		$	604
Warranties and guaranties accrued		16			23			38			57
Expenses paid and adjustments		(54	)		(8	)		(103	)		(31	)

Ending Balance	$	547		$	630		$	547		$	630

In some cases, a performance bond may be purchased and held for the period of the warranty that can be used to satisfy the obligation.

Line of Credit

Clean Coal has available a revolving line of credit with a bank for $10 million that is secured by substantially all assets of Clean Coal (including the interests it owns in its subsidiaries). The line of credit expires in March 2013 and requires quarterly interest payments. Borrowings under the line of credit bear interest at the higher of the “Prime Rate” (as defined in the related credit agreement) plus one percent (1%) or 5% per annum. At June 30, 2011, the outstanding balance on the line of credit was $4,168,000 and the effective interest rate was 5% per annum. Borrowings under the line of credit are subject to certain financial covenants applicable to Clean Coal.

Litigation

The Company is involved in litigation with 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 on adjusted sales of AC from the Red River plant. The payment schedule for the awarded obligations is expected to be determined when the final award is issued by the arbitration panel within the next few months. The Company expects to record a liability for the royalty payments concurrent with future sales from Red River as they are known. Approximately $1.6 million has been recorded for the six months ended June 30, 2011 related to the projected liability for royalty payments through 2011.

The Company has accrued current liabilities of approximately $33 million which is included in accrued arbitration award and related liability and a long-term liability of approximately $6.9 million which is included in accrued arbitration award on the accompanying consolidated balance sheets related to these awards. The final award will also address the potential for payment of legal fees incurred by Norit. The Company has made no accrual for potential payment of any such legal fees as such amounts, if any, cannot be determined at this time.

Carbon Solutions

In 2008, the Company made certain guaranties and undertook other obligations related to Carbon Solutions. No liabilities associated with such guaranties and obligations were recorded on the Company’s consolidated balance sheet as the Company does not expect such guaranties and obligations to be called upon.

Summaries of the guaranties and obligations related to Carbon Solutions are as follows:


	As of June 30, 2011
	(In thousands)
AC Facility construction contract ¹	$	13,200
Equipment contracts ²		4,500
Sales contract A guarantee ³		10,000
Sales contract B guarantee ⁴		1,000

Total guaranties and obligations	$	28,700

The Company has guaranteed all amounts owed by Red River under its construction contract for the AC Facility. The amount shown is the approximate remaining obligation under the contract. Red River can terminate this contract at any time and would be liable for certain items. The general contractor for the AC Facility has filed a lien on the AC Facility and a statement of claim against Red River and ADA totaling $21 million related to dispute of contract costs.

Red River entered into four contracts with an independent equipment supplier for the purchase of certain equipment. A parent guaranty is applicable to both the Company and our partner in the joint venture. The amount shown is the approximate remaining obligation remaining under these contracts. Red River may terminate these contracts at any time and would be liable for certain items.

The Company has also guaranteed the obligations of Red River under an amended sales contract with a major electric power generating company. Both parties are entitled to require specific performance of the other in limited circumstances when the cover remedies prove inadequate. No later than five business days after the third party debt financing portion for the AC Facility is obtained, each party is obligated to deliver to the other a $10 million standby, unconditional, irrevocable letter of credit to secure the obligations to the other party in the event of default.

⁴

The Company has also guaranteed the obligations of Red River under an amended sales contract with a different major electric power generation company. The guaranty is effective until Red River has fulfilled its contractual obligations, which is estimated to occur in the second quarter of 2012, and may be terminated earlier based on Red River’s financial position or the credit rating of its debt financing for the AC Facility. This is the Company’s maximum aggregate liability under the guaranty.

Under terms of agreements with Carbon Solutions, as amended in August, 2009, Red River has agreed to reimburse the Company and ECP in the event they are required to make payments related to any of the above noted guaranties and guaranties provided by ECP and has granted a secured interest in its assets to ADA and ECP to secure the reimbursement agreement and any loans ECP makes to Red River. Carbon Solutions has guaranteed the obligations of Red River under the reimbursement and loan agreement and has pledged its equity interest in Red River to the Company and ECP as security for this guaranty. The Company has assigned its rights under these agreements to ECP, and any amounts payable to the Company would be paid directly to ECP until ECP’s preferred equity in Carbon Solutions is fully redeemed or converted and all loans to Red River have been paid in full.

Under the terms of the JDA, the Company is required to indemnify ECP and Carbon Solutions for certain damages and expenses they incur with respect to the Company’s litigation and arbitration with Norit discussed above and described below in Part II, Item 1.

Following is a summary of contributions made by ECP:


	As of June 30, 2011		As of December 31,2010
	(unaudited, in thousands)
Preferred equity contributions	$	86,400	$	89,300
Loans and accumulated interest payable to Red River by secured notes bearing interest at 12% per annum compounded quarterly.	$	208,800	$	193,800

Clean Coal

The Company also has certain guaranties and obligations in connection with the activities of Clean Coal. The Company, NexGen and two entities affiliated with NexGen have provided the lessee of its RC facilities and GS with joint and several guaranties (the “CCS Party Guaranties”) guaranteeing all payments and performance due under the related transaction agreements. The Company 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. The parent of the lessee in the RC facilities lease transactions has provided Clean Coal with a guaranty as to the payment only of 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.

(11)

Income Taxes (restated)

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.

In August 2012, after extensive discussions with the SEC’s Division of Corporation Finance and Office of the Chief Accountant and the Company’s outside tax experts, independent registered public accounting firm, Audit Committee and Board of Directors, management determined that the objective and verifiable negative evidence represented by historical losses outweighed more subjective positive evidence of anticipated future income. As a result, management determined it necessary to record a full valuation allowance against the Company’s net deferred tax assets and is restating its consolidated financial statements with this Amendment for the quarterly period ended June 30, 2011 and as of December 31, 2010. See Note 13 for additional discussion.

The Company has provided a full valuation allowance against the deferred tax assets of $21.2 million and $15.7 million as of June 30, 2011 and December 31, 2010, respectively.

The tax benefit included in the consolidated statement of operations for the three and six months ended June 30, 2011 was recorded as a result of the sale of the equity interest in Clean Coal to GS in May 2011. Since the transaction did not result in a change in control of Clean Coal, the $11 million tax effect of the amount received from this transaction was recorded to stockholders’ deficit.

Business Segment Information (restated)

The following information relates to the Company’s three reportable segments: Emission Control (“EC”), CO2 Capture (“CC”) and Refined Coal (“RC”). All assets are located in the U.S. and, other than RC segment assets that include assets under lease and other development costs totaling $9.8 million at June 30, 2011 and $5.3 million at December 31, 2010, are not evaluated by management on a segment basis.

Restatement of Consolidated Financial Statements

Reclassification of Equity Interest

On its Current Report on Form 8-K dated June 20, 2012, the Company reported management’s determination that the Company’s consolidated financial statements contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2011 and its Quarterly Reports on Form 10-Q for the quarters ended June 30, 2011, September 30, 2011 and March 31, 2012 should no longer be relied upon and should be restated. Management made this determination following an assessment of the accounting treatment of the equity in Clean Coal that has been held by an affiliate of GS since May 2011.

After completion of a review and evaluation of the operating agreement of Clean Coal and the members’ rights and obligations thereunder and accounting authoritative literature, management determined that GS’s interest in Clean Coal would be more appropriately classified as temporary equity because of a provision in the agreement that permits GS to require redemption of the unreturned portion of its initial investment plus a return of 15% under certain limited circumstances.

As a result, the Company has restated its consolidated financial statements in this Amendment for the period ended June 30, 2011. The effect of the restatement on the Company’s consolidated balance sheet as of June 30, 2011 and consolidated statement of changes in stockholders’ equity (deficit) for the six months ended June 30, 2011 is that GS’s interest in Clean Coal has been reclassified as temporary equity rather than as part of stockholders’ equity (deficit). In addition, the consolidated statement of cash flows for the six months ended June 30, 2011 has been restated to reflect the entire investment by GS as a financing activity rather than an investing activity.

Deferred Tax Assets Valuation Allowance

On its Current Report on Form 8-K dated August 14, 2012, the Company reported management’s determination that the Company’s consolidated financial statements contained in its Annual Reports on Form 10-K for the fiscal years ended December 31, 2010 and 2011 and its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2011, June 30, 2011, September 30, 2011, March 31, 2012 and June 30, 2012 should no longer be relied upon and should be restated.

After extensive discussions with the SEC’s Division of Corporation Finance and Office of the Chief Accountant and the Company’s outside tax experts, independent registered public accounting firm, Audit Committee and Board of Directors, management determined that a full valuation allowance against the Company’s net deferred tax assets should have been recognized as of December 31, 2010 and for each subsequent quarter thereafter. 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 deferred tax assets.

Realization of the deferred tax assets is dependent upon the Company’s ability to generate future taxable income. In its reassessment, management concluded that the objective and verifiable negative evidence represented by historical losses outweighed more subjective positive evidence of anticipated future income. As a result, the Company has restated its consolidated financial statements in this Amendment for the quarterly period ended June 30, 2011 and as of December 31, 2010.

Financial Statement Effect of the Restatement

The tables below show the effect of the above restatement on the Consolidated Balance Sheets as of June 30, 2011 and December 31, 2010, Consolidated Statement of Operations for the three and six months ended June 30, 2011, Consolidated Statement of Changes in Stockholders’ Equity (Deficit) for the six months ended June 30, 2011 and Consolidated Statement of Cash Flows for the six months ended June 30, 2011. The restatement reflects non-cash adjustments and has no effect on previously reported operating income results or cash flows from operations.

The forward-looking statements contained in this Report are presented as of the date hereof, and we disclaim any duty to update such statements unless required by law to do so.

Restatement

With this Amendment we have restated the following previously filed consolidated financial statements, data and related disclosures: Consolidated Balance Sheets as of June 30, 2011 and December 31, 2010, Consolidated Statement of Operations for the three and six months ended June 30, 2011, Consolidated Statement of Changes in Stockholders’ Equity (Deficit) for the six months ended June 30, 2011 and Consolidated Statement of Cash Flows for the six months ended June 30, 2011. The restatement reflects non-cash adjustments and has no effect on previously reported operating income results or cash flows from operations. The following Management Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) should be read in conjunction with the unaudited consolidated financial statements and notes thereto, included in Item 1 of this Amendment, and the audited consolidated financial statements and notes thereto and the MD&A included in the Company’s Amendment No. 2 to its Annual Report on Form 10-K/A for the fiscal year ended December 31, 2010 filed on October 19, 2012, as well as the Company’s other filings with the SEC.

The restatement results from management’s determination that the Company had not properly accounted for the interest held by an affiliate of the Goldman Sachs Group (“GS”) in our joint venture, Clean Coal Solutions, LLC (“Clean Coal”) since May 2011 and that a full valuation allowance against the Company’s net deferred tax assets should have been recognized as of December 31, 2010 and all subsequent quarters thereafter.

The following MD&A incorporates the restated figures reflecting these changes. For this reason the data set forth in this section may differ from that presented in discussions and data in our previously filed Quarterly Report on Form 10-Q for the period ended June 30, 2011.

Overview

We develop, offer and implement proprietary environmental technology and market specialty chemicals to the coal-burning electric utility industry, to the Portland cement industry and to industrial boiler operators. We have three operating segments: emission control (“EC”); CO2 capture (“CC”) and refined coal (“RC”). The EC segment includes the supply of emission control systems including powdered activated carbon injection (“ACI”) systems, acid gas mitigation systems and the sale of specialty chemicals, equipment and services for flue gas conditioning projects, the licensing of certain technology, consulting services related to such matters and other applications. The CC segment includes projects relating to the CO2 capture and control market, including projects co-funded by government agencies, such as the DOE. The RC segment includes revenues from the leasing of two facilities and the development and sale of technology, services and equipment for the RC market.

We conduct research and development efforts in CO2 capture and control from coal-fired boilers. On September 30, 2010, we signed our second significant contract related to CO2 capture with the DOE, which is scheduled to continue through the end of 2014. We are marketing our RC technology, services and equipment through our interest in our Clean Coal joint venture with NexGen Refined Coal, LLC (“NexGen”), an affiliate of NexGen Resources Corporation, and with an affiliate of The Goldman Sachs Group, Inc. (“GS”). We currently own interests in two operating RC facilities through Clean Coal which leases them through its subsidiaries to another GS affiliate. The two RC facilities are operated by Clean Coal Solutions Services, LLC (“CCSS”), a Colorado limited liability company owned 50% by us and 50% by NexGen. In addition, the Carbon Solutions joint venture, of which we owned 22.8% as of June 30, 2011, has commenced commercial operations at its AC Facility whose production is focused primarily on emissions control applications related to mercury emissions from coal burning utilities.

Emission Control

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 since it was issued 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 requires the EPA to issue 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 a draft of the Proposed Mercury and Air Toxics rules, a MACT based hazardous pollutant regulation, which provides for among other provisions, control of mercury and volatile metals such as arsenic, selenium and acid gases such as HCl and other Hazardous Air Pollutants (“HAPs”) (the “Mercury and Air Toxics Rule” or “MATR”). The proposed rule was officially listed by the EPA in the Federal Register on May 5, 2011 with comments due back by August 4, 2011. The draft MATR is based upon the average of the best-performing 12% of power plants and only allows minimal averaging or trading. The MATR proposed a limit for mercury emissions that will require capture of 80% to 90% of the mercury in the coal burned in electric power generation boilers. While the new regulations will require additional emission control equipment, the EPA estimates a small percentage of the current generation fleet will retire due to the cost of complying with the regulations.

In addition to the electric power generators, the EPA has developed a MACT-based mercury emissions regulation for the Portland Cement Industry through proposed amendments to the National Emission Standards for HAPs for the Portland Cement Manufacturing Industry (the “Cement MACT”). The Cement MACT regulation was finalized on September 9, 2010. On May 7, 2011, the EPA denied requests to issue an administrative stay on the Cement MACT and denied and granted in part various petitions to reconsider the final revised Cement MACT. The EPA is not delaying the implementation of the Cement MACT and is only reconsidering various technical standards and issues contained in the final regulation, which we do not believe will have a material impact on the regulation and its eventual implementation. This regulation requires cement plants to reduce HAPs by 2013 including 92% of mercury and 83% of hydrocarbons. 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 our 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. We believe the Cement MACT will increase the market for both ACI systems and AC.

The EPA has also issued a new MACT regulation for coal-fired boilers that provide mostly steam and/or electricity for small industrial and institutional power needs with no more than 25 MW of electricity sold to the grid (the “Industrial Boiler MACT”). The final regulation was released on February 23, 2011 and issued on March 21, 2011, with compliance deadlines originally scheduled for early 2014. The EPA delayed the effective date of the final rule implementation of the Industrial Boiler MACT until such time as judicial review is no longer pending or until such time as the EPA completes its reconsideration of the related rules. The EPA is reconsidering various aspects of the regulation including its application to a wide variety of boiler types and fuels. In addition, proposed legislation in the United States Senate (S. 1392) would provide additional time for the EPA to reconsider the regulation and would extend the period in which regulated boilers must be brought into compliance to five years, rather than the normal three years.

The Industrial Boiler MACT could impact over 600 existing coal-fired industrial boilers. The final emission limit of 4.6 pounds of mercury per Trillion BTU for existing and two pounds per Trillion BTU for new coal-fired industrial boilers will on average require < 50% capture of mercury from coal-fired boilers burning various coals. We believe the final Industrial Boiler MACT could increase the market for ACI systems by several hundred and the associated AC by approximately 50 million pounds per year when considering the requirement to control both mercury and dioxin/furans under this final rule that can be controlled by use of activated carbon injection. These totals could be even higher, when considering that 400 or more biomass and wood fired boilers are also covered under this regulation.

The Clean Air Act requires that all emission control related regulations be met within 36 months. 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 in choosing low capital expense control technologies and likely fewer forced retirements from having to install large capital equipment, such as scrubbers and baghouses. We anticipate the final MATR will create a large market for our mercury control products beyond 2011. We expect that as many as 1,200 existing coal-fired boilers will be affected by such regulations, if and when they are fully implemented. We believe that the MATR will be made final by the November 2011 deadline. Many power companies recognize the urgency of these pending regulations, and as a result we are contracting with power plants to evaluate mercury control options at a number of their plants. Utilities need to know as soon as possible whether their existing EC components are sufficient to meet the new test limits with the installation of ACI and dry sorbent injection (“DSI”) systems. If they need to upgrade their equipment with new fabric filters or possible scrubbers, they need to quickly begin procurement of that large capital equipment due to long required lead times. This could result in near-term ACI demonstration revenue and positions us to bid on related ACI equipment.

ACI Systems and Services

To date, we have installed or are in the process of installing 49 ACI systems. Some market demand continues in 19 states that either have passed their own mercury control regulations or have entered agreements with power plants to reduce mercury emissions for new power plants. We remain active in the bid and proposal process and expect the number of awards this year to remain flat or decline compared to last year. Although we expect the equipment market to continue to be static in 2011, we believe we have the opportunity for significant revenue growth for our EC products and services when final federal regulations or legislation affects a significant portion of previously uncontrolled and existing boilers. Given the current expected timing for finalization of the MATR, we anticipate the need for 400 to 700 ACI systems to be supplied between 2012 and 2015, which would require rapid scale-up of our production capabilities to maintain our approximate 30% market share. For an average Electric Generating Unit, the ACI equipment costs are between $600,000 and $1 million. We are expanding our sales staff as well as our engineering design group and fabrication capacity to meet this anticipated market. We believe contracts for ACI systems will not begin to be awarded until later this year when the rule is made final, but we are already in discussions with some utilities about early fleet-wide procurement.

We have also developed and are offering commercial systems to inject dry alkali sorbents for control of acid gases such as SO3 and HCl as well as for control of the criteria pollutant SO2. DSI systems, which cost approximately $2 million to $3 million for an average size plant, provide a low-capital cost alternative to scrubbers for meeting certain provisions of the MATR and the Cross State Air Pollution Rule, which was finalized by the EPA on July 6, 2011 (“CSAPR”, formerly known as the “Transport Rule”). CSAPR replaces the EPA’s 2005 Clean Air Interstate Rule and requires 27 states in the eastern half of the United States and the District of Columbia to significantly improve air quality by reducing power plant SO2 and nitrogen oxide emissions that contribute to ozone and fine particle pollution in other states. Plants in the 27 impacted states will be required to comply with emission reductions quickly; beginning January 1, 2012 for SO2 and annual nitrogen oxide reductions, and May 1, 2012 for ozone season nitrogen oxide reductions. We conducted full-scale tests of the DSI equipment in 2010 and for the past year ADA has been demonstrating DSI equipment for the control of SO2 and SO3 on plants burning bituminous, Powder River Basin (“PRB”), and lignite coals. The DSI approach is also a low-cost option for utilities for meeting the particulate matter standard proposed in the MATR because dry sorbents can capture condensable material that are part of the regulated particulate matter emissions. Experts have predicted that up to a quarter of the 1,200 plus coal fired boilers could be forced to shut down if they were required to add scrubbers and selective catalytic reduction systems which can cost $200 million to $300 million per installation.

We are developing and providing services and bidding on systems to measure and mitigate acid gases from coal fired boilers. These acid gas emissions are often the unintended result of the retrofit and operation of NOx control technology on medium to high sulfur coal-fired boilers.

Arch Coal Development and License Agreement for Enhanced Coal

Since 2004, we have been working with Arch Coal to explore certain unique characteristics of some types of coals produced by Arch Coal that allow them to be burned with lower emissions. We believe a recent technical breakthrough provides a potential means to obtain similar performance improvements from all of Arch Coal’s PRB coals. As a result on June 25, 2010, we entered into a Development and License

Agreement (the “License Agreement”) with Arch Coal. Pursuant to the License Agreement, we provided Arch Coal with an exclusive, non-transferable license to use certain technology to produce “Enhanced Coal” by the application of ADA’s proprietary coal treatment technology for coal mined by Arch Coal at mines and sites located in the PRB. We expect that the technology will reduce certain emissions from the burning of the PRB coal, which should help to meet the MATR. Pursuant to the License Agreement, we are providing development services to Arch Coal aimed at applying the technology to the PRB coal. In addition, if we develop improvements to the technology that are related to the reduction of certain emissions from the burning of PRB coal, that technology 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.

In consideration for the development work and the license to Arch Coal, Arch Coal paid us an initial, non-refundable license fee in cash of $2 million in June 2010 and we have recognized $735,000 of such amount as revenue for the six months ended June 30, 2011 in addition to amounts recognized in 2010. Arch Coal may be obligated to make royalty payments to us that could amount to as much as $1 per ton of the premium for “Enhanced Coal” sold by Arch Coal, depending upon the successful implementation of the technology and the premium Arch Coal is able to charge on future sales of the “Enhanced Coal” product. Arch Coal currently produces more than 100 million tons of PRB coal per year. 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.

The License Agreement contains standard indemnification provisions customary for license agreements, including indemnification by us for any losses suffered by Arch Coal as a result of any claims for infringement by the technology as to intellectual property rights of any third party. Either party may terminate the License Agreement upon written notice to the other party if the other party materially breaches any material term of the License Agreement, generally with a right to cure a breach within 30 days. In addition, if we materially breach the provisions of the License Agreement relating to ownership of the related technology and maintaining confidential information, and fail to correct any such breach within 30 days, the licenses granted to Arch Coal become fully paid-up, perpetual and irrevocable, without any further obligation of Arch Coal to pay any ongoing royalty.

In recent tests we have shown that we can enhance PRB coal at the mine and achieve mercury reductions when the coal is burned at power plants. We believe the coal enhancement provides a $1 to $4 per ton benefit of coal to the power plants. The proposed MATR could create a market for a significant percentage of the greater than 100 million tons per year of PRB coal mined by Arch. Because of our focus on placing in service additional RC facilities prior to the end of this year, additional demonstrations of our Enhanced Coal product have been delayed. We expect to resume these tests later this year and in 2012 which will provide sufficient time to grow this business as the national mercury control market expands through 2015.

As a part of entering into the License Agreement we agreed to negotiate and enter into a Supply Agreement under which Arch Coal will purchase the chemicals described in the License Agreement exclusively from us. We expect to negotiate the final terms of the Supply Agreement in the next six months.

CO₂ Capture

In addition to our two key growth areas, emissions control and RC, we continue to demonstrate our position as a premier developer of innovative clean energy technologies. Control of CO2 from coal-fired power plants is currently a topic of discussion in Washington and a significant issue for the coal industry as a result of the impact of CO2 emissions on climate change. We see this as an opportunity and have begun developing technologies to address the needs of our customers through reduction of CO2 generation and CO2 capture.

DOE is funding CO2 control projects related to our business and on September 30, 2010, we signed a new contract with them to continue development of clean coal technology to capture CO2 from coal-fired power plants and other industrial sources of CO2 emissions. We are the prime contractor for the approximately $19 million project administered by DOE’s National Energy Technology Laboratory which is providing $15 million of the funding. We expect approximately $4 million in co-funding and support to be provided by several major electric power generation companies including Southern Company, Luminant and the Electric Power Research Institute, Inc. The project provides funding to advance our commercialization plan for regenerable solid-sorbent technology, which is designed to capture CO2 generated by coal-fired power plants.

In 2010 we began the first field tests of our CO2 control technology on a $3.8 million program co-funded by DOE, as well as several major forward-thinking 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. Once captured, the CO2 could be either stored underground (sequestration) or beneficially used in processes such as enhanced oil recovery. This capture technology appears to offer potential cost and energy advantages over competing liquid-solvent-based technologies.

In October 2010 we began work on the new DOE CO2 project, which is expected to run for a total of 51 months to scale-up the technology to the one-megawatt level, which is a key step in the technology development process. This contract will not only fund research and development (“R&D”) on this technology, but it is expected to provide significant contributions to our revenue and margin over the next three plus years.

We anticipate that DOE programs will continue to represent an important component of the revenue stream of the Company over the next several years as we position ourselves for the market growth for ACI systems, enhanced coal and related technology with Arch Coal and other technologies for emissions control.

Refined Coal

Environmental Legislation and Regulations and Opportunities

Clean Coal’s primary opportunity is based on Section 45 tax credits for the production of refined coal and proprietary technology developed by ADA that has been licensed to Clean Coal. In December 2009, the IRS issued guidance as to the specifics concerning how the emissions reductions are to be measured and certified to demonstrate compliance necessary to qualify for the Section 45 tax credits and under the Tax Relief and Job Creation Act of 2010, the deadline for placing qualifying facilities into service was extended to December 31, 2011. The tax credits amount to an annually escalating $6.33 per ton of RC for a period of ten years for facilities placed in service prior to January 1, 2012.

As a result of the extension of the placed in service deadline, we are pursuing strategic relationships to sell or lease several additional RC facilities during 2011 with a potential of up to 16 total RC facilities. Thus far Clean Coal has built the generic portions of 10 facilities to address its anticipated opportunities each capable of producing one to five million tons of RC per year. In June of this year, Clean Coal installed and placed in service one of these units at a plant that is expected to burn up to four million tons of RC per year. This new facility was operated for the period of time deemed necessary to meet the IRS placed in service deadline, and when burned, the RC produced demonstrated the reductions in mercury and NOx emissions necessary to qualify for the Section 45 tax credit. Clean Coal has also installed four additional facilities at power plants burning an aggregate of over 10 million tons of coal per year; however, initial operations and testing were postponed for several weeks because of the severe heat wave in the Midwest. We expect these four units to be placed in service some time before September of this year. Following the completion of the facility demonstrations, operating permits and contracts between the utilities and the financial institution monetizing the tax credits will need to be finalized prior to commencing full-time operations to produce RC, which we expect to take four to six months per facility and occur late in the fourth quarter of this year as to these four units. We expect the remaining 11 facilities to be placed in service this fall. We believe the market potential for the additional 16 facilities to be approximately 30 million tons in the aggregate, which we estimate to be a 50% market share.

Based on the current Section 45 tax credits, we expect Clean Coal to generate revenues from leasing or selling RC facilities to financial parties or generate tax credits by retaining and operating the RC facilities that we expect to meet the placed in service deadline through December 31, 2021. Upon expiration of the tax credits on December 31, 2021, the leases of our RC facilities to financial parties will terminate. We may then lease the RC facilities directly to the utilities or operate them on behalf of utility customers given the significant benefit of the resulting mercury reductions such facilities provide. The tax credits would no longer be available absent further extension by Congress.

Clean Coal is financing the construction and installation of the additional RC facilities with the Line of Credit described below. In addition, we are negotiating terms with monetizers to provide advance payments of rent once the facilities are placed in service and become operational.

Clean Coal Existing Facilities, Leases and Related Agreements

Clean Coal placed two RC facilities in service prior to January 1, 2010 (the original placed in service deadline under Section 45) and demonstrated the required emission reductions for their RC product to qualify for the Section 45 tax credits. On June 29, 2010, Clean Coal executed contracts by which the two existing RC facilities were leased to GS RC Investments LLC, (“GSRC”, which is another affiliate of GS), the lessee. The leases have base terms that run through December 31, 2012 (the “Initial Term”), and automatically renew for annual terms through the end of 2019. The other 50% voting interest in Clean Coal is owned by NexGen and the two RC facilities are owned, respectively, by two special purpose entities (the “Lessors”). Clean Coal owns 95%, and we and NexGen each own 2.5% of the Lessors. The lessee has entered into supply agreements for each RC facility pursuant to which it supplies RC to the applicable power plant owner. CCSS (subject to oversight by the lessee) operates and maintains the RC facilities under two Operating and Maintenance Agreements entered into with the lessee as part of the transaction. In addition to reimbursement for costs incurred, CCSS receives a fee of $.08 per ton of coal processed through the RC facilities for its services. The lessee pays the costs for operating and maintaining the RC facilities, subject to certain limitations. CCSS also arranges for the purchase and delivery of certain chemicals necessary for lessee’s production of RC under two supply agreements entered into with the lessee as part of the transaction. CCSS receives a fee for its services in the amount of 5% of the cost of chemicals and transportation costs. The term of each supply agreement runs coincident with the leases.

We, Clean Coal and the lessee also entered into a technology sublicense agreement (the “Technology Sublicense”) pursuant to which we licensed, and Clean Coal sublicensed, to the lessee certain technology required to operate each RC facility and to produce RC. The Technology Sublicense parallels the license previously granted by us to Clean Coal and requires that we stand behind Clean Coal if it fails to perform its obligations under the sublicense, other than as a result of a default by lessee. The agreement contains representations and warranties customary for such agreements regarding intellectual property, and, subject to certain liability limits, requires us to indemnify the lessee in the event of certain infringement claims by a third party. We are also obligated to actively prosecute infringement of the technology by third parties, or to cooperate with the lessee if it does so, in which case any award would go to the lessee and any other sublicensee who prosecutes the infringement. The annual license fee payable to Clean Coal for the sublicense is $10,000 per year, but this amount is deductible from the amount the lessee pays in rent under the leases.

In addition, we, NexGen and two entities affiliated with NexGen have provided the lessee 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 (the “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. The parent of lessee provided Clean Coal with a guaranty as to the payment only 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 September 2010, the RC facilities ramped up production to expected continuous levels and are now treating over 95% of the available coal used by the four generating units at the two power plants. During the first six months of 2011, these two units generated over $10 million in consolidated revenues for ADA. These production levels are expected to generate between approximately $15 million to $20 million per year in revenues and, after deduction of NexGen’s and GS’s share, between approximately $7 million to $9 million in pre-tax cash flow and operating income, or approximately $1 per diluted share annually for ADA through 2019 (assuming no significant change in outstanding number of shares).

Organization and Control

We originally formed Clean Coal in 2006, and sold a 50% interest in it to NexGen for $1 million. Under the original Purchase and Sale Agreement, NexGen had the right (but not the obligation) to maintain its 50% interest in Clean Coal by paying us an additional $4 million at certain specified times. In October, 2009, NexGen elected to retain its interest in Clean Coal and issued $1.8 million two-year promissory notes to the Company in June 2010, with the remainder of the payment to come from 25% of cash distributions (other than for income taxes) due to NexGen from Clean Coal.

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, equal to approximately 15.8 units of non-voting Class B membership interests, to an affiliate of GS for $60 million in cash (the “Purchase Price”) pursuant to a Class B Unit Purchase Agreement (the “Purchase Agreement”). In conjunction with the closing of the Purchase Agreement, we, NexGen and GS entered into a Second Amended and Restated Operating Agreement for Clean Coal (the “Restated Operating Agreement”) and an Exclusive Right to Lease Agreement (the “Lease Agreement”). Pursuant to the Restated Operating Agreement, we and NexGen each exchanged 50 units of membership interests in Clean Coal for approximately 42.1 voting Class A Units in Clean Coal, representing a total of approximately 84.2% of the equity interests in Clean Coal following the Transaction. ADA and NexGen each received $30 million as a result of the sale, and subsequent to the transaction with GS, NexGen paid the Company the remaining balance due of $1.8 million as payment in full of the amount owing by NexGen to maintain its interest in Clean Coal, including payment in full of all other amounts owing to us totaling $480,000 under certain previously issued “tonnage notes.”

Pursuant to the transaction with GS, we and NexGen provided GS with joint and several guarantees (the “Limited Guarantees”) guaranteeing the performance by Clean Coal of its obligation to indemnify GS against certain losses it may suffer as a result of inaccuracies or breaches of the representations and warranties made by Clean Coal in the Purchase Agreement or the Lease Agreement, or if Clean Coal breaches its covenants in the Purchase Agreement or the Lease Agreement. Clean Coal’s indemnification obligations for breaches of representations, warranties and covenants, other than for breaches of the representations involving organization, subsidiaries, capitalization and voting rights, authority and non-contravention and valid issuance, are subject to a non-recoverable deductible of $500,000 and a cap of the Purchase Price. We also entered into a contribution agreement with NexGen under which any party called upon to pay on a Limited Guaranty is entitled to receive contribution from the other party equal to 50% of the amount paid.

The rights and obligations of the parties are set forth in detail in the Restated Operating Agreement, which provides, among other related terms and conditions, that prior to April 1, 2012, Distributable Cash (as defined in the Restated Operating Agreement) will be distributable approximately 84.2% to us and NexGen as holders of the Class A Units and approximately 15.8% to GS as the holder of the Class B Units. Given the 2.5% direct interest both we and NexGen retain in subsidiaries of Clean Coal previously formed to operate any RC facilities, the effective sharing ratio of net cash generated by all expected refined coal operations is 15% to GS and 85% to us and NexGen. Beginning with distributions made after December 31, 2012, Clean Coal must distribute no less than 70% of Distributable Cash, at least annually. Within 10 days of April 1, 2012, Clean Coal must calculate a “Projected Distributable Value,” which is defined in the Restated Operating Agreement as an estimated amount equal to the net present value, using a 15% discount rate, that Clean Coal projects it will receive through the end of the term of all effective (i.e., contractually committed) RC facilities. For distributions occurring after April 1, 2012, if 15.8% of the Projected Distributable Value is equal to or greater than GS’ “Unrecovered Investment Balance” (which is the dollar amount necessary, at any given time, to return GS at least its $60 million investment, plus a 15% return thereon, taking into account all prior distributions to GS), GS is entitled to receive 15.8% of each distribution. If the “Projected Investment Value” (which is 15.8% of the Projected Distributable Value) is less than the Unrecovered Investment Balance as of the time for any given distribution, then an adjustment will be made to the distribution ratios to compensate GS for this deficiency. This adjustment is to be updated from time to time over the life of the investment, and at any time when Projected Investment Value becomes equal to or greater than GS’ Unrecovered Investment Balance, the amount payable to GS again becomes 15.8% of the distribution (or a lesser amount if amounts previously distributed have resulted in overpayments to GS). Clean Coal may make greater distributions to GS than required at any given time in order to shorten the time in which the Unrecovered Investment Balance will be reduced to $0.

In addition, the Restated Operating Agreement provides that upon the occurrence of a Liquidation Event (as defined in the Restated Operating Agreement), GS will be entitled to receive the greater of (A) a liquidation preference in an amount equal to the Unrecovered Investment Balance as of the date of such Liquidation Event (the “Liquidation Preference”) or (B) GS’ pro rata share of the proceeds from such Liquidation Event.

Furthermore, the Restated Operating Agreement states that on or after the earlier of (i) a breach of any material provision of the Purchase Agreement or Clean Coal’s organizational documents that is not cured in accordance with the Restated Operating Agreement and that results in damages to GS of at least $10 million or (ii) the 10 year anniversary of the date the last refined coal facility owned by Clean Coal or one of its subsidiaries is placed in service (but in no event later than December 31, 2021), and if the Unrecovered Investment Balance has not been reduced to zero, GS may require its Class B Units to be redeemed by Clean Coal for an amount equal to its Unrecovered Investment Balance, payable within 180 days of the notice of redemption. In addition, the Restated Operating Agreement contains provisions in regard to GS’ right to a board observer, each parties’ rights and obligations with respect to capital calls, preemptive rights, approval of certain transactions, drag-along and tag-along rights, a covenant not to compete, an obligation for us to present certain related “business opportunities” to Clean Coal for its consideration and related matters.

Pursuant to the Lease Agreement, Clean Coal granted GS the exclusive right (but not the obligation) to lease facilities that will produce up to approximately 12 million tons (+/- 10%) (the “Target Tons”) of refined coal per year on pre-established lease terms similar to those currently in effect for Clean Coal’s two existing facilities, but which are more economically favorable to Clean Coal than the rates in the present leases for the existing refined coal facilities that Clean Coal leased to another GS affiliate in June, 2010. Clean Coal is required to submit a package to GS with

respect to each RC facility it proposes that GS 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 GS, GS is required to pay Clean Coal, as a deposit, an agreed amount for each 1 million tons of projected annual refined coal production. Upon closing of a lease of a RC facility from Clean Coal, GS is required to pay Clean Coal an additional amount per 1 million tons of projected annual refined coal production. These payments are paid as advance rent, and actual amounts due under the leases (with true-ups) will be paid in accordance with the operative lease and related agreements, which will be based on the forms of documents that were used in the transactions for the existing RC facilities leased to GSRC and will include guaranties by us and NexGen. The initial lease terms will be five years, with annual renewals for five successive one-year periods. If GS determines that it wishes not to lease a RC facility after it has paid the deposit, it can demand 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 demand is made. The amount of any deposit will earn interest from the date of demand until the deposit is paid.

In connection with the transaction, including the entry into the Lease Agreement, Clean Coal and GSRC agreed to cancel the existing “first right of refusal” that was previously granted to GSRC under the existing agreement to lease in connection with the leasing by GSRC of two existing RC facilities. Under the cancelled first right of refusal GSRC had the first right to lease RC facilities with up to 14 million tons of refined coal production per year.

Since its inception, we have been considered the primary economic beneficiary of Clean Coal and have consolidated its accounts in our financial statements, but we do not consolidate the results of CCSS because NexGen controls the entity pursuant to the operating agreement of the entity. The leases for Clean Coal’s existing RC facilities included an upfront payment of $9 million in prepaid rent for both facilities and provide for fixed rent and contingent rent based upon future production of RC, each of which is payable on a quarterly basis. We are recognizing the prepaid rent over the initial three year term of the leases. Such revenues are recorded as they are earned. Historically, the utilities at which the facilities operate have used over six million tons of coal per year, which amount can vary based on several factors. The 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 tax credits. Each lease may be terminated by the lessee for various reasons, the most significant of which are:

•

For any reason as of the end of the initial term by giving notice by no later than July 1, 2012.

•

If the Total Operating Expenses (as defined in each lease) paid by the lessee for two consecutive quarters exceed 140% of the projected operating costs for the RC facility.

•

If any of Lessor’s representations or warranties were breached as of the date made and such breach is not cured within 30 days after notice.

•

If a change of law, or certain other specified events affecting the availability of the Section 45 credits, occurs.

•

Upon the occurrence of a governmental regulatory event that would make the contemplated transaction impermissible.

In order to maintain our 50% voting interest in Clean Coal, we are obligated to fund half of its operating costs and capital expenditures. We expect the operations of the RC facilities to generate sufficient working capital to meet their operating needs. On March 31, 2011, Clean Coal entered into a credit agreement with a bank for $10 million that is secured by substantially all assets of Clean Coal (including the interests it owns in its subsidiaries) (the “Line of Credit”). The Line of Credit expires in March 2013 and requires quarterly interest payments. Borrowings under the Line of Credit bear interest at the higher of the “Prime Rate” (as defined in the related credit agreement) plus one percent (1%) or 5% per annum. At June 30, 2011, the outstanding balance on the Line of Credit was $4,168,000 and the effective interest rate was 5% per annum. Borrowings under the line of credit are subject to certain financial covenants applicable to Clean Coal.

Carbon Solutions

Carbon Solutions, our joint venture company with ECP, has constructed the AC Facility through its wholly owned subsidiary Red River. The AC Facility, which achieved commercial operation in May 2010, is operating and currently supplying customers with AC. In the second half of 2010 the AC passed certification testing that will allow it to be sold into the water market.

Under the terms of the Limited Liability Company Agreement (the “LLC Agreement”) of Carbon Solutions among ECP and ADA, we have contributed $25.6 million in cash and other property and ECP has contributed cash of $175.7 million, including preferred equity contributions of $86.4 million, through June 30, 2011. Effective June 2009 and since that date, ECP converted some of its preferred equity contributions to ordinary capital contributions resulting in a dilution of our ownership percentage to 22.8% as of June 30, 2011 and as a result, we include our share of Carbon Solutions’ loss under the equity method of accounting. Our initial investment combined with our share of Carbon Solutions’ cumulative losses to date has resulted in a net investment in Carbon Solutions of $9.8 million as of June 30, 2011. We do not have any further capital commitments to Carbon Solutions, and expect that all future funding for the AC Facility will come from ECP and third-party debt financing. See “Liquidity and Capital Resources” below for additional information.

Carbon Solutions predicts a significant gap between AC production and demand beginning in 2012, with the gap growing close to a billion pounds per year after all the MACT regulations are in place by 2015. They believe that the growth anticipated will require up to five additional AC production lines of the same size and capacity as Red River. To prepare for the additional demand created by the draft Air Toxics Rule, Carbon Solutions has permitted a second 150 million pound per year production line at the Red River plant. We have certain rights to participate by up to 50% in capacity additions Carbon Solutions may pursue.

In addition, we provide certain services to Carbon Solutions under a Master Services Agreement (“MSA”). Sales and other revenues under the MSA totaled $22,000 and $52,000 for the three and six months ended June 30, 2011, respectively, which amounts are included in EC revenues in the accompanying consolidated statement of operations.

Results of Operations – 2nd Quarter and YTD 2011 versus 2nd Quarter and YTD 2010

Revenues totaled $7 million and $15.5 million for the three and six months ended June 30, 2011, respectively, versus $1.9 million and $5.8 million for the three and six months ended June 30, 2010, respectively, representing an increase of 263% and 167% for the quarter and year to date. We expect overall revenues for the rest of the year to be higher than those reported for the 2010 period primarily as a result of the impact from the RC segment.

Cost of revenues decreased by $78,000 and $1.3 million or 4% and 29% for the three and six months ended June 30, 2011, respectively, from the same periods in 2010 primarily as a result of decreased revenues in our EC and CC segments and lower RC segment costs as described below. Gross margins were 74% and 80% for the three and six months ended June 30, 2011, respectively, compared to less than 1% and 23% for the same periods in 2010. The increase primarily reflects the increased RC margins and revenues as described below. For the near term, we expect the sales related to the RC segment 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 2011 to be higher than the overall margin realized in 2010.

Emission Control

Revenues in our EC segment totaled $1.7 million and $3.7 million for the three and six months ended June 30, 2011, respectively, representing an increase of 7% and a decrease of 20% from the same periods in 2010. The amounts reported exclude the work ADA has conducted for Clean Coal, as further described below, which was eliminated in our consolidation. Revenues from the EC segment for the six months ended June 30, 2011 were comprised of sales of ACI systems and services (30%), flue gas chemicals and services (15%) and other services (55%), compared to 77%, 3%, and 20%, respectively, for the same period in 2010. For the near term, we expect the consulting services in our EC segment to increase as a percentage of EC revenues as the industry seeks to analyze and evaluate the MACT regulations in addition to increased revenues related to our technical breakthrough related to PRB coal. We expect our EC segment revenues related to ACI systems to remain at static levels until such time as utilities, cement plants and industrial boilers start to react to the MACT regulations. We expect overall gross margins for the EC segment for 2011 to be higher than levels achieved in 2010.

Our consulting revenues increased approximately $603,000 and $1.1 million during the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010 as we began demonstration and other work related to recent changes with the MACT regulations and includes revenues totaling $333,000 and $667,000, respectively, from our Arch Coal non-refundable license. Our consulting revenues contributed approximately $1.1 million and $1.9 million during the three and six months ended June 30, 2011 and we expect our consulting revenues to increase as a percentage of EC revenues during the remainder of 2011 as several customers are seeking advice and evaluation studies on how best to comply with the finalized MACT regulations.

As of June 30, 2011, we had contracts in progress for work related to our EC segment totaling approximately $2.1 million, of which we expect to recognize a significant portion during the remaining six months of 2011, with the balance to be completed and realized in 2012. Our ACI systems revenues totaled $488,000 and $1.1 million for the three and six months ended June 30, 2011, respectively, representing a decrease of 57% and 68% compared to the same periods in 2010. In the EC segment, we performed work related to RC systems provided to Clean Coal valued at $359,000 and $471,000 for the three and six months ended June 30, 2011, respectively, that would otherwise be recognized as revenue but were eliminated in the consolidation of Clean Coal. In the EC segment, we performed work related to RC systems provided to Clean Coal valued at $2.7 million and $3.2 million for the three and six months ended June 30, 2010, respectively, that would otherwise be recognized as revenue but were eliminated in the consolidation of Clean Coal. The prior year includes our participation in the construction and installation of the initial RC facilities that were placed in service in at the end of 2009. In the current year, Clean Coal is utilizing a number of additional resources for of the planned new RC facilities.

Cost of revenues for the EC segment decreased by $237,000 and $1.2 million for the three and six months ended June 30, 2011, respectively, from the same periods in 2010, primarily as a result of the decreased revenue-generating activities from our ACI system sales. Gross margins for the EC segment were 44% and 52% for the three and six months ended June 30, 2011, respectively, compared to 25% and 35% for the same periods in 2010. The increase in gross margin from the prior year was primarily a result of cost savings from original budgeted amounts when the contracts commenced.

EC segment profits increased by $118,000 or 193% and decreased by $76,000 or 8% for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010. The decrease in the six-month period was primarily a result of decreased ACI system sales.

CO₂ Capture

Revenues in our CC segment totaled $569,000 and $917,000 for the three and six months ended June 30, 2011, representing an increase of 69% and decrease of 20% from the same periods in 2010. We had outstanding DOE contracts, including anticipated industry cost share in progress totaling approximately $17.9 million as of June 30, 2011. We expect to recognize approximately $1.6 million from these contracts during the remainder of 2011 including participation by other industry partners and the remainder in 2012 through 2014. As discussed above, on September 30, 2010 we signed a contract on a DOE project totaling approximately $19 million (including expected contributions by other industry partners). Revenues increased in the second quarter due to the increased activities under this contract.

Cost of revenues for the CC segment increased by $332,000 and $351,000 for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010. Gross margins for this segment were 16% and 17% for the three and six months ended June 30, 2011, respectively, compared to 57% and 64% for the same periods in 2010. The decrease in gross margin from 2011 to 2010 is due primarily to greater use of subcontractors for which our margins are less under these projects. 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 2011 to be lower than the levels achieved in 2010, due to the mixture of direct costs (labor versus equipment) associated with this segment.

CC segment profits decreased by $150,000 and $634,000 or 88% and 95% for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010. As discussed above, the decrease was primarily the result of greater use of subcontractors and lower cost share participation. 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 2004 and later have not been finalized. 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.

Refined Coal

Revenues in our RC segment totaled $4.7 million and $10.8 million for the three and six months ended June 30, 2011, respectively. There were no similar revenues during the same period in 2010 as the facilities were not placed into routine operations until the end of the second quarter of 2010. RC revenues were lower than in the first quarter of this year due to planned maintenance outages in April and May at the power plants where the RC facilities operate which reduced the amount of coal available for processing. We expect coal processed in the third and fourth quarters of this year to return to the levels we saw in the first quarter. We expect our quarterly revenues 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. The first two systems are expected to produce approximately 6 million tons of RC annually, qualifying for the present $6.33 per ton Section 45 tax credit through 2019.

Cost of revenues for the RC segment totaled $413,000 and $588,000 for the three and six months ended June 30, 2011 respectively, compared to $586,000 and $1.0 million for the same periods in 2010 as we had increased our efforts earlier in 2010 in further developing the technology and modifying the equipment. Costs for the quarter ended June 30, 2011 increased compared to the first quarter of 2011 due to activities undertaken to place additional facilities into operations. Costs of revenues have stabilized as the existing RC facilities have settled into routine operations. We expect future RC margins to be at a level near 95%.

RC segment profits increased by $4.7 million and $10.9 million for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010 as the two facilities were leased and placed in routine operation in the middle of 2010.

Other Items

General and administrative expenses increased by $671,000 and $909,000 or 11% and 8% to $6.8 million and $11.7 million for the three and six months ended June 30, 2011, respectively, from the same periods in 2010. The change in 2011 resulted primarily from $3.0 million in incentive compensation for employees and consultants we accrued during the three months ended June 30, 2011 related to the equity sale in Clean Coal. These increases were somewhat offset by decreases in legal expenses totaling $2.8 million and $3.5 million for the three months and six months ended June 30, 2011, respectively over the same periods in 2010. Non-routine legal costs related to the Norit matter totaled $ 1.5 million and $3.4 million for the three and six months ended June 30, 2011, respectively. We expect non-routine legal costs to decrease significantly starting in the fourth quarter of 2011 assuming we can resolve the Norit arbitration and related indemnity claims by then. We expect other components of our G&A to increase in 2011 as we build our infrastructure in preparation for the increased market opportunities anticipated from the several MACT regulations.

We incur research and development (“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 expenses increased by $178,000 and $315,000 or 90% and 83% for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010 as a result of increases in CC and RC activities. We have had no significant direct cost share for R&D under DOE related contracts so far in 2011 or in 2010. The increase in total R&D is related to preparing for growth in the delivery of our ACI systems, as well as our RC activities. 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 2011 compared to 2010. 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 net interest and other income and net interest income of $1.5 million and $2.1 million for the three and six months ended June 30, 2011, respectively, compared to $1.8 million for both the three and six months ended June 30, 2010 due primarily to the interest on notes receivable and other amounts received from NexGen. We recognized $39.5 million in expenses for the six months ended June 30, 2011 related to the interim award in the Norit arbitration as described below and in Part II, Item 1 of this report.

The deferred income tax benefit of $11 million (restated) for the six months ended June 30, 2011 represents the income tax effect of the sale of the equity interest in Clean Coal to GS in May 2011. The consolidated financial statements have been restated to include a full valuation allowance against the deferred tax assets as discussed in Notes 11 and 13 of the notes to the restated consolidated financial statements. Our income tax rate does not include any material amount of Section 45 tax credits from Clean Coal as those tax benefits will primarily be realized by the lessee under the RC facilities’ leases.

Our net loss for the six months ended June 30, 2011 of $35.4 million (restated) or $(4.64) (restated) per share includes our equity in the losses incurred by Carbon Solutions totaling $1.8 million and $3.8 million for the three and six months ended June 30, 2011, respectively and is included in other income (expense) in the consolidated statement of operations. This amount is reported net of our equity in the net income of CCSS which amounted to $74,000 and $100,000 for the three and six months ended June 30, 2011, respectively. We expect to continue to report our equity in the losses of Carbon Solutions for the balance of the year and future years as sales ramp up and other development activities continue. Our investment in Carbon Solutions has been reduced by our respective share of such losses. We expect to continue to report our equity in the net income of CCSS for the balance of the year as operations become more consistent.

Liquidity and Capital Resources

Working Capital

Our principal sources of liquidity are the proceeds we received from the sale of equity in Clean Coal, our other working capital and our anticipated cash flow from RC activities and other operations. We had consolidated cash and cash equivalents totaling $41 million at June 30, 2011 compared to consolidated cash and cash equivalents of $9.7 million at December 31, 2010.

At June 30, 2011, we had a working capital deficit of $716,000 (restated) compared to working capital of $9.9 million (restated) at December 31, 2010. Our working capital decreased primarily due to the reclassification from long-term to current of $32.6 million in liabilities related to the interim Norit matter, partially offset by proceeds from the sale of an effective 15% interest in the equity of Clean Coal to GS. ADA received gross proceeds of $30 million from the sale of Class B units to GS and received an additional amount of $1 million from NexGen representing the remaining payment owed by NexGen in order to maintain its interest in Clean Coal. In addition, we received payment on notes receivable and other receivables from NexGen totaling $2 million We have long-term liabilities recorded totaling $38.5 million which amount includes our present estimate of the long-term liability portion of the interim award related to the Norit matter of $6.9 million, long-term deferred revenue including deferred rental income and other obligations of $2.4 million, and an estimate of indemnity costs related to the Norit award of $29.1 million as of June 30, 2011. Although we had positive operating cash flow for the six months ended June 30, 2011, this trend will likely not continue during the remainder of 2011, depending upon the timing of payments related to the Norit interim award and indemnity costs. We expect Clean Coal to use its $10 million line of credit and cash flow from operations to fund amounts required to construct, install and place additional RC facilities into operation.

Our stockholders’ deficit was approximately $78.5 million (restated) as of June 30, 2011 compared to $2.2 million (restated) as of December 31, 2010. The increase in deficit is primarily due to the expenses recorded related to the Norit interim award, the recording of the sale of temporary equity in Clean Coal to GS, and the recording of a valuation allowance against the Company’s net deferred tax assets (see Note 13 for the effect of the restatement on stockholders’ equity (deficit)).

Carbon Solutions has funded, through loans and/or equity contributions from ECP to Carbon Solutions, a significant portion of the legal expenses related to the Norit matter. In April 2011, ECP notified us that it believes our indemnity obligations to it and Carbon Solutions totaled approximately $30.7 million, inclusive of the $29.1 million recorded on our balance sheet. In the past ECP has claimed that our indemnity obligations also include any losses it may suffer due to loss of potential customers and diminution in the value of the business, legal costs and fees and any damages it may suffer as a result of a lawsuit Norit International N.V. f/k/a Norit N.V. (“Norit International”) has filed against ECP in state court in New Jersey. Satisfaction of a portion of our indemnity obligations to ECP could be made via a decrease in our recorded capital contributions (and with a corresponding increase in ECP’s capital contributions) in Carbon Solutions and adjustment of each party’s percentage ownership accordingly.

Our ability to generate the financial liquidity required to meet ongoing operational needs and to meet our obligations related to the Norit arbitration and litigation will likely depend upon several factors, including ongoing legal expenses incurred by us (and other parties) in the Norit matters, timing of satisfaction and ultimate amount of payments due to Norit and payment of our indemnity obligations, our ability to maintain a significant share of the market for mercury control equipment, Clean Coal’s continued operation of the two RC facilities placed in service in 2010 and success in monetizing Section 45 tax credits through the sale or lease of additional RC facilities to third party investors and our ability to raise additional financing. Depending upon these factors and further proceedings in the Norit arbitration as to timing of payment of the $37.9 million interim award and possible award of legal fees and costs to Norit, which Norit claims to be $13 million, we may not have sufficient working capital to meet our obligations and may need to seek protection in the courts for our assets by filing a Chapter 11 bankruptcy proceeding. Court protection could allow us to continue to operate our business and provide us with additional time to negotiate or otherwise attempt to restructure our debts. Management believes that given the Company’s options, resolution of the Norit arbitration and payment of obligations to Norit and payment of the other related indemnity obligations to ECP will not prevent the Company from meeting its obligations to customers and vendors and operating its business.

Clean Coal Related Items

Clean Coal, our joint venture with NexGen and GS, has placed two RC production facilities into service, which have been leased to a third party. Based on the amount of RC that we expect will be produced from the RC facilities, we expect to recognize pre-tax tax cash flows between $7 million to $10 million per year through 2019, the expected period for which Section 45 tax credits are available for these facilities.

During the second quarter of 2011 and subsequent to the sale of an effective 15% interest in Clean Coal to GS as described above, NexGen completed its obligation to ADA in order to maintain its interest in Clean Coal. In June 2010, NexGen executed $1.8 million in two-year promissory notes with interest at 5% per annum. During the second quarter of 2011 and subsequent to the sale of the interest in Clean Coal to GS as described above, NexGen paid the entire balance due of $3 million plus interest to maintain its interest in Clean Coal.

In addition, ADA, NexGen and two entities affiliated with NexGen have provided Clean Coal’s sublessee with joint and several guaranties guaranteeing any payments and performance due the lessee under the various agreements Clean Coal executed in the lease of the RC facilities.

AC Facility Related Items

As noted above, Carbon Solutions has commenced commercial operations at its AC Facility, which has an estimated all-in, total cost for one production line capable of producing approximately 150 million pounds of AC per year including related activities of approximately $400 million. Red River has received a conditional commitment for up to $245 million from the DOE to guarantee a loan related to the costs of construction of the AC Facility.

In order to address the anticipated capital needs of Carbon Solutions, ECP may fund additional ordinary capital contributions or preferred equity contributions to Carbon Solutions or make loans to Red River, in each case at such times and in such amounts as ECP determines are necessary to satisfy their capital requirements. Neither ADA nor ECP is required to fund additional capital contributions to Carbon Solutions at this time. One-half of ECP’s preferred equity bears a preferred return of 12% per annum, and the other half does not bear a preferred return. ECP is entitled to receive priority distributions on its preferred equity until it is redeemed or converted and has the option to convert any such unredeemed preferred equity into ordinary capital contributions.

Pursuant to an Amended and Restated Credit and Reimbursement Agreement among Red River, ECP and ADA dated as of September 2, 2009 and related documents (the “Carbon Solutions’ Credit Support Documents”), ECP may make loans to Red River from time to time. As of June 30, 2011, the principal balance of ECP’s loans to Red River totaled approximately $175.7 million. Such loans are evidenced by convertible demand promissory notes bearing interest at 12% per annum compounded quarterly. ECP may convert any outstanding amounts due under such notes to ordinary capital or preferred equity contributions in Carbon Solutions at any time at its option. The outstanding loans are secured by Red River’s assets and guaranteed by Carbon Solutions, and Carbon Solutions’ guaranty is secured by a pledge of Carbon Solutions’ equity in Red River. If and when Carbon Solutions is able to place long-term commercial debt, we expect a significant portion, if not all, of its outstanding loans from ECP to be replaced by such debt.

In 2009 and subsequently, ECP has converted some of its then outstanding preferred equity to ordinary capital contributions and made additional ordinary capital contributions, resulting in dilution of our ownership interest in Carbon Solutions to 22.8% as of June 30, 2011. Because of such dilution to date, ECP now elects three out of the four managers of the Board of Carbon Solutions and controls decisions of the Board and the members. We continue to have the right to participate in significant decisions subject to member approval so long as we continue to hold at least a 15% ownership interest. Member approval requires approval of members holding at least 75% of the ownership interests so our approval is no longer required.

In addition to our indemnity obligations described above, we have given guaranties and undertaken other commitments of approximately $28.6 million related to Carbon Solutions. No liabilities associated with such guaranties and obligations were recorded in the financial statements as we do not expect the guaranties and commitments to be called upon. The general contractor for the AC Facility has filed a statement of claim against ADA and Red River and a lien on the AC Facility for $21 million related to a dispute of contract costs. Pursuant to the Carbon Solutions’ Credit Support Documents, Red River has agreed to reimburse us and ECP in the event we or they are required to make payments related to these guaranties and guaranties provided by ECP. Red River’s reimbursement obligations are secured by Red River’s assets and guaranteed by Carbon Solutions, and Carbon Solutions’ guaranty is secured by a pledge of Carbon Solutions’ equity in Red River. We assigned our rights under these agreements to ECP, and any amounts payable to us would be paid directly to ECP until ECP’s preferred equity in Carbon Solutions is fully redeemed or converted and all loans to Red River have been paid in full.

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 June 30, 2011 our trade receivables balance was $6.9 million which was offset by billings in excess of recognized income of $281,000 for a net of $6.7 million compared to $8.6 million at December 31, 2010.

We recorded approximately $1.7 million in additional potential indemnity obligations to Carbon Solutions related to the running royalty portion of the Norit award. We also recorded approximately $39.5 million in interim award obligations, including both expected current and long-term amounts, related to the Norit matter during the six months ended June 30, 2011 as well as $1.6 million of accrued expenses which resulted in the increase in accrued current liabilities as of June 30, 2011.

Under our defined contribution and 401(k) retirement plan, in 2011 and 2010 we matched up to 7% of salary amounts deferred by employees in the plan. During the six months ended June 30, 2011 and 2010, we recognized $182,000 and $132,000, net of forfeitures, respectively, of matching expense which payments were made with our stock. In the past, we have also made discretionary contributions to the plan for employees. Thus far in 2011, and in 2010, we did not make any such discretionary contributions. Our matching expense is expected to amount to $300,000 for 2011 depending on employee participation in the plan.

We had net current deferred tax assets of $129,000 and net long-term deferred tax assets of $21.1 million as of June 30, 2011 compared to net current deferred tax assets of $188,000 and net long-term deferred tax assets of $15.5 million as of December 31, 2010. The current and long-term amounts for both periods have subsequently been reduced to zero by recording a full valuation allowance. As discussed above and in Notes 11 and 13 to the restated consolidated financial statements, in August 2012, after extensive discussions with the SEC’s Division of Corporation Finance and Office of the Chief Accountant and the Company’s outside tax experts, independent registered public accounting firm, Audit Committee and Board of Directors, management determined that a full valuation allowance against the Company’s net deferred tax assets should have been recognized as of December 31, 2010 and for each subsequent quarter thereafter. 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 deferred tax assets.

Cash flow provided by operations totaled $5.9 million for the first six months of 2011 compared to $9.1 million for the same period in 2010. The change in operating cash flow primarily resulted from an increase in accrued arbitration award and other liabilities of $39.5 million, an increase in our accrued indemnity liability of $1.7 million, a decrease in accounts receivable of $2.4 million and an increase in accounts payable and accrued liabilities of $2.2 million which were offset by a decrease in deferred revenue of $2.5 million. These changes in our operating assets and liabilities correspond to 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 $636,000, depreciation and amortization of $392,000, non-controlling interest in Clean Coal of $3.8 million and our net minority equity interest which increased our cash flow provided by operations and were offset by an increase in recorded deferred tax benefits of $11 million (restated) related to the sale of equity in Clean Coal to GS.

Net cash used in investing activities was $3.4 million (restated) for the first six months of 2011 compared to $3.2 million for the same period in 2010. Cash used in investing activities consisted of purchases of equipment and development projects of $5 million offset by payments of $1.6 million received from NexGen related to their notes receivable to us. The cash used in 2010 was primarily due to capital expenditures related to our Clean Coal joint venture. The remaining cash used in 2010 was made up of investments in securities and activities related to the development and formation of our investments in other entities.

Net cash provided by financing activities was $28.8 million (restated) for the first six months of 2011 compared to $273,000 used for financing activities for the same period in 2010. Sources of financing included the $60 million equity contribution from the sale of the interest in Clean Coal, net borrowings on the line of credit of $4.2 million and equity contributions of $250,000, offset by distributions to the non-controlling interest of $35.7 million (restated).

Critical Accounting Policies and Estimates (restated)

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

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

•

our allowance for doubtful accounts, which is based on historical experience;

•

our warranty costs;

•

our estimate of timing, amount and payment on contingent liabilities;

•

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; and

•

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

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 evaluate the current net book value of goodwill and other intangible assets of $761,000 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 could 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 – Our equity partner in Carbon Solutions, ECP, contributed equity capital significantly in excess of our contributions. We expect that our ownership percentage may be further diluted below the 22.8% existing as of June 30, 2011 and that we will continue recording our interest under the equity method.

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. ADA holds a 50% interest in the Class A voting units of Clean Coal, and an affiliate of The Goldman Sachs Group, Inc. holds a non-voting interest in Clean Coal and shares in the profits or losses of the joint venture.

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.

Recently Issued Accounting Policies

There were none issued which were material to our financial statements.

Item 4.

Controls and Procedures (restated).

We 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

When our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2011 was filed on August 12, 2011, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2011. Subsequent to that evaluation, our management identified errors related to the accounting for the equity investment in Clean Coal that has been held by an affiliate of GS since May 2011 and the establishment and maintenance of a valuation allowance against deferred tax assets, as discussed below. These errors had a material effect on our previously issued consolidated financial statements. As a result of these errors, we determined that the consolidated financial statements for the fiscal years ended December 31, 2010 and 2011 and the quarters ended March 31, 2011, June 30, 2011, September 30, 2011, March 31, 2012 and June 30, 2012 should not be relied upon and needed to be restated (see Note 13 in the accompanying restated consolidated financial statements for further discussion) and identified the material weaknesses described below.

Changes in Internal Control Over Financial Reporting

In connection with the identification of the errors related to our financial statements described above and in Note 13 to our restated consolidated financial statements, management has identified the following deficiencies that constituted material weaknesses in our internal control over financial reporting for the periods described above:

•

We did not maintain an effective control environment, as evidenced by not utilizing appropriate personnel or consultants qualified to review complex, non-routine business transactions that require additional review and impact decisions requiring accounting treatment, financial statement presentation and disclosure.

•

We did not establish adequate criteria to assess positive and negative evidence over the establishment and maintenance of a valuation allowance against deferred tax assets and an appropriate review process over the inputs and conclusions from this assessment was not in place.

Accounting errors resulting from the material weaknesses described above resulted in the need to restate our annual and interim consolidated financial statements.

Remediation of Material Weakness

To address these material weaknesses, we have undertaken the following remedial steps. First, in July 2012, in order to remedy the material weakness related to the accounting for the equity investment in Clean Coal that has been held by an affiliate of GS since May 2011 described above, we engaged an accounting and tax expert for the purpose of performing detailed accounting analysis of complex, non-routine business transactions. This enables management to make timely decisions regarding required disclosure relating to such items. Management has re-evaluated the operational effectiveness of our internal controls over financial reporting and with the addition of the reviews now being provided by our external resources believes that the material weakness which had previously existed has been fully remediated.

Second, by establishing a valuation allowance against the Company’s deferred tax assets, management believes that the material weakness which had previously existed with respect to the deferred tax assets has been fully remediated. As disclosed in previous amended filings, to ensure that such an issue does not arise again in the future, the Company is in the process of creating a formal process related to the design and implementation of controls and establishment of adequate criteria to assess the positive and negative evidence over the establishment and maintenance of a valuation allowance against deferred tax assets. Management anticipates that this process will include periodic oversight by the Audit Committee and anticipates completing this remediation effort before the Annual Report on Form 10-K for the fiscal year ending December 31, 2012 is filed.

We will continue to monitor the effectiveness of our internal control over financial reporting in the areas affected by these material weaknesses described above and employ any additional tools and resources as appropriate to provide reasonable assurance that our financial statements are fairly stated in all material respects.

As previously disclosed, there were no changes in our internal controls over financial reporting during the quarter ended June 30, 2011, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. As described above, we have taken steps subsequent to the period covered by this Amendment to remedy the material weaknesses in our internal control over financial reporting.
