Defendants and the AC Venture Defendants for the Incurred Legal Fees the ECP Defendants and the AC Venture Defendants agree to accept, and ADA agrees that it is liable for and shall pay, as full and final settlement, the amount of $29,163,273
provided that such amount is paid as provided in the section titled “Payment of Settlement Fee Amount” below (the “Settlement Fee Amount”).

 
 In consideration of the promises and mutual agreements contained in this Agreement,

Agreement.
		
	 Additional Legal Fees

and Expenses
	  	 Additional Legal Fees: Except as otherwise provided in this Section, ADA, on the one hand, and the ECP Defendants
and the AC Venture Defendants, on the other hand, shall pay all their respective legal fees, costs and expenses they incur arising after the Legal Fee Settlement Date resulting from, arising out of or relating to the Norit Litigation, including
without limitation, the Final Award and the Settlement Agreements.
  

Control of Actions or Proceedings or Other Disputes: The ECP Defendants or the AC Venture Defendants may, but shall not be obligated to, elect, at
any time and from time to time, to control any Action or Proceeding or other dispute (including counterclaims) resulting from, arising out of or relating to the Norit Litigation, including, without limitation the Final Award, the Other Awards and
the Settlement Agreements (the “Norit Matters”), involving any ECP Defendant or AC Venture Defendant, which control shall include full authority to settle the Norit Matters (the “Control Option”); provided, however,
that if (1) ADA is current with respect to its monetary obligations pursuant to this Agreement, including to pay the Royalty Payments and with respect to the amount of the Periodic LC (including, without limitation, all Litigation Postings) and the
Security LC and (2) to the extent any such settlement concerns Royalty Payments, the settlement must be presented to ADA for its approval (the date such proposal is delivered to ADA, the “Notification Date”), which approval shall
not be unreasonably withheld. The ECP Defendants and the AC Venture Defendants shall keep ADA apprised of any settlement discussions that concern potential Royalty Payments. Within five business days after the Notification Date, ADA must (1) consent
to the settlement or (2) increase the Periodic LC (the terms of which are set forth below in the paragraph titled “Prepayment of Periodic Royalty Amounts”) in the amount set forth below (each such amount, a “Litigation
Posting”).
  

•      Initial Litigation Posting: At the time ADA rejects any
settlement proposal, the Periodic LC amount shall be increased by an amount equal to the difference between (1) the amount of Royalty Payments that have been made up to such time pursuant to the Final Award and (2) the amount of Royalty Payments
that would have been due or made up to such time if Norit is granted the relief it is requesting in such Norit Matters or if such Norit Matters are otherwise decided in Norit’s favor.

 

•      Subsequent Litigation Postings: After the initial increase in
the Periodic LC to address a particular rejected settlement proposal, each forecast prepared

	  


  
 5 









			
		  	 pursuant to the paragraph below titled “Good Faith Forecast of Periodic Royalty Amount” during the
pendency of the Norit Matters shall include an additional amount equal to the difference between (1) the amount of Royalty Payments that would be made pursuant to the Final Award during the period provided for in such paragraph and (2) the amount of
Royalty Payments that would be required to be made during the period provided for in such paragraph if Norit is granted the relief it is requesting in such Norit Matters or if such Norit Matters are otherwise decided in Norit’s favor, and such
amount shall be added as a separate item in the Royalty Notice. In no event shall the subsequent Litigation Postings include amounts duplicative with the initial Litigation Posting provided for in the immediately preceding paragraph. Any amounts
included in the Royalty Notice on account of the Norit Matters shall be clearly set out in the Royalty Notice as amounts to secure a disputed liability and such amounts shall be added to the Periodic LC (the terms of which are set forth below in
section titled “Prepayment of Periodic Royalty Amounts”).
  
 If
within five business after the Notification Date, (1) ADA fails to reply regarding whether it consents to the proposed settlement or (2) ADA notifies the ECP Defendants and the AC Venture Defendants that it does not consent to the settlement,
but fails to make the Litigation Posting within five business days after the Notification Date, then ADA shall automatically be deemed to have consented to the settlement.

 
 If (1) within five business day after the Notification Date ADA notifies the ECP
Defendants and the AC Venture Defendants that it does not consent to the settlement and (2) within five business days after the Notification Date ADA makes the Litigation Posting, then the ECP Defendants and the AC Venture Defendants shall,
within five business days of the later of such notification or posting, notify ADA if (A) they elect to continue to control the Norit Matters to which the settlement relates on their behalf (and not on behalf of ADA), in which case the ECP
Defendants and/or the AC Venture Defendants shall continue to pay all the legal fees, costs and expenses they incur in connection with such Norit Matters or (B) they elect to allow ADA to assume control of such Norit Matters on behalf of the ECP
Defendants and/or the AC Venture Defendants with counsel of ADA’s choosing, in which case ADA shall pay all of the legal fees, costs and expenses ADA incurs on behalf of the ECP Defendants and the AC Venture Defendants in connection with such
Norit Matters.
  
 To the extent that the ECP Defendants and/or the AC Venture
Defendants elect to continue to control any such Norit Matters on



  
 6 









			
		  	 their own behalf after ADA has withheld consent to a settlement, the ECP Defendants and/or the AC Venture Defendants shall have sole
authority over the conduct of their prosecution or defense of such Norit Matters on their own behalf, and ADA shall be from that point solely responsible for its prosecution or defense of such Norit Matters on its own behalf and ADA shall pay all
the legal fees, costs and expenses it incurs in connection with such Norit Matters. All parties shall be free in such case to settle such Norit Matters on its own behalf without prejudice to the other parties.

 
 To the extent that the ECP Defendants or the AC Venture Defendants do not elect to
exercise their Control Option at the initiation of a particular Norit Matter, ADA may, but shall not be obligated to, elect to control such Norit Matter, which control shall include full authority to settle such Norit Matter. Any Party not
controlling such Norit Matter may at any time retain separate counsel to represent it at its sole cost and expense. The obligation of ADA to indemnify the ECP Defendants and the AC Venture Defendants pursuant to the section titled “ADA
Indemnification Obligations for Royalty Payments” shall not be altered in any manner as a result of any such Norit Matter (1) including if no Party elects to control or otherwise defend such Norit Matter (in which case such indemnification
obligations shall include any default judgment or similar award entered in such Norit Matter), (2) regardless of which Party, if any, controls any such Norit Matter and (3) regardless of the outcome, including, without limitation, the terms of any
settlement (including, without limitation, settlements that ADA is deemed to have automatically consented to pursuant to the provisions of this section) of any such Norit Matter.

		
	 Losses Arising from
 Royalty Payments
	  	ADA Indemnification Obligations for Royalty Payments: ADA agrees that, notwithstanding the joint and several obligations of ADA, ACS and RREP set forth in Sections 2
(Scope of Royalty), 3 (Royalty Terms and Rates), 4 (Payment), 6.d (Audit Costs and Variances) and 7 (Late Payments) in the Final Award, as between ADA on the one hand, and ACS and RREP on the other hand, ADA is obligated to (1) pay Norit any and all
amounts due pursuant to such sections of the Final Award with respect to the existing activated carbon manufacturing facility located in Coushatta, Louisiana consisting of four contiguous multi-hearth furnaces and the related equipment (the
“Red River Plant”) and the existing Natchitoches facility (together with the Red River Plant, the “Existing Carbon Facilities”) (the “Royalty Payments”) and (2) indemnify the ECP Defendants and the
AC Venture Defendants against all Losses suffered, incurred or sustained by any of them or to which any of them becomes subject, resulting from, arising out of or relating to ADA’s failure to make the Royalty Payments, all of which shall
constitute Losses (as defined in the JDA). The Parties further agree that in the event any additional carbon production facilities are constructed or operated by the AC Venture Defendants, or any Affiliates or Subsidiaries thereof, after the date of
this Agreement (hereinafter “New Carbon Facilities”), and


  
 7 









			
		 	notwithstanding the joint and several obligations of ADA, ACS and RREP set forth in Sections 2 (Scope of Royalty), 3 (Royalty Terms and Rates), 4 (Payment), 6.d (Audit Costs and
Variances) and 7 (Late Payments) in the Final Award, as between ADA on the one hand, and ACS and RREP on the other hand, ACS and RREP (1) are obligated to pay Norit any and all amounts due pursuant to such sections of the Final Award with respect to
the New Carbon Facilities and (2) ADA shall have no liability for, and no indemnity obligation with respect to, any and all amounts due to Norit pursuant to such sections of the Final Award with respect to the New Carbon Facilities.
		
		 	Good Faith Forecast of Periodic Royalty Amounts: On the fifth business day after the end of each calendar quarter the AC Venture Defendants shall in good faith prepare an
estimate (based upon projected or actual customer shipments and deliveries for then-existing contracts of the AC Venture Defendants and spot sales) of the amount of the Royalty Payments related to the quarter just ended and shall deliver written
notice (each, a “Royalty Notice”) to ADA setting forth in reasonable detail the amount and the basis for the forecast of the Royalty Payments (each, and as adjusted by the true up mechanism detailed below, a “Periodic
Royalty Amount”). On the first business day of a month during which a Royalty Payment is due to Norit, the AC Venture Defendants shall in good faith prepare a final statement of the amount of such Royalty Payment (the “Final
Quarterly Royalty Amount”) and shall deliver written notice to ADA setting forth in reasonable detail the basis for the Final Quarterly Royalty Amount and ADA shall pay such amount to Norit pursuant to Section 4 of the Final
Award.
		
		 	The AC Venture Defendants shall provide to ADA the royalty reports provided to Norit pursuant to Section 5 of the Final Award substantially concurrently with when such reports
are provided to Norit. The AC Venture Defendants shall also provide to ADA and ADA shall provide to the ECP Defendants and the AC Venture Defendants all documents and information they exchange with Norit concerning or relating in any manner to the
Norit Litigation, including, but not limited to, the documents and information exchanged relating to Norit’s exercise of its audit rights under the Final Award. Such documents and information shall be provided substantially concurrently with
when such documents and information are exchanged with Norit. Information that would otherwise be provided directly to ADA, the ECP Defendants and the AC Venture Defendants, as applicable, pursuant to this paragraph may be designated as “highly
confidential” by ADA, the AC Venture Defendants and/or the ECP Defendants, as applicable, and such highly confidential information shall be disclosed in the case of ADA only to the Auditing Accountant and outside counsel for ADA and in the case
of the ECP Defendants and the AC Venture Defendants only to their outside counsel and any outside audit firm retained by them. The Auditing Accountant, such outside audit firm and such outside counsel shall agree not to provide such
information


  
 8 









			
		 	to ADA, the ECP Defendants and the AC Venture Defendants, as applicable, their respective Subsidiaries and other Affiliates and their respective directors, officers, employees,
servants, agents, trustees, insurers, co-insurers, reinsurers, and shareholders. (i.e., “attorneys eyes only”), except as such disclosure may be required by applicable law, in which case ADA, the ECP Defendants and the AC Venture
Defendants, as applicable, shall inform the other parties of the disclosure.
		
		 	If requested by ADA, the AC Venture Defendants shall meet and confer with ADA, the Auditing Accountant and/or outside counsel, as applicable, regarding the method and approach used
by the AC Venture Defendants to calculate the Royalty Payments in the statements and reports prepared in accordance with the preceding two paragraphs. If ADA disagrees with any such method or approach after meeting and conferring with the AC Venture
Defendants, ADA shall have the option, but not the obligation, to raise, at its sole cost and expense, its objection to such calculation with any arbitration panel empowered in the Arbitration Action to enforce the Final Award, and all Parties shall
be bound by any final determination of the amount of the Royalty Payments due pursuant to the procedures set forth in the Final Award or as otherwise determined by any panel in the Arbitration Action. Nothing in this paragraph shall relieve ADA of
its obligations pursuant to any provision of this Agreement, including, without limitation, the obligation to fund the Periodic LC with the Periodic Royalty Amount as detailed on the Royalty Notice delivered by the AC Venture Defendants or to pay
the Final Quarterly Royalty Amount as determined by the AC Venture Defendants.
		
		 	 Prepayment of Periodic Royalty Amounts: Within five(5) business days after receipt of a Royalty Notice, ADA shall prepay the
Periodic Royalty Amount and any Litigation Posting by delivering (or revising an outstanding Periodic LC amount) to the AC Venture Defendants an irrevocable standby letter of credit (the “Periodic LC”) containing the following
terms:
  

•      Stated Amount: Not less than the Periodic Royalty Amount
(including the amount of all Litigation Postings).
  
 •      Beneficiaries: The AC Venture Defendants obligated to make Royalty Payments, and, in the event of any Litigation Posting, the ECP Defendants and the AC
Venture Defendants that are parties to the particular Norit Matters for which a Litigation Posting was made.
  

•      Issuing Institution: An Approved Institution (as herein
defined).
  

•      Drawing: The beneficiaries may draw upon the letter of credit 8
business days prior to the due date of any Royalty Payment not previously paid by



  
 9 









			
		 	 ADA and may draw the full amount of such letter of credit at any time between the 29th day prior to the expiration of the letter of credit and the
date of the expiration of the letter of credit if a new letter of credit has not been provided with terms no less favorable than the existing letter of credit and, in the event of any Litigation Posting, the beneficiaries may draw upon the letter of
credit upon the failure by ADA to pay any amounts due pursuant to this Agreement related to the particular Norit Matters for which the Litigation Posting was made.

		
		 	 •      Term: The Periodic LC delivered to the AC
Venture Defendants as prepayment of the Periodic Royalty Amount must be Continually in Place until the later of (1) at least 120 days after the date the corresponding Royalty Payment is due to Norit and (2) at least 30 days after the
performance of all actions or obligations of ADA, the AC Venture Defendants and the ECP Defendants related to the particular Norit Matters for which the Litigation Posting was made. Amounts in the Periodic LC attributable to the Periodic Royalty
Amount shall remain a part of the Periodic LC until 120 days after the date the corresponding Royalty Payment is due to Norit and amounts in the Periodic LC attributable to a Litigation Posting shall remain part of the Periodic LC until 30 days
after the performance of all actions or obligations of ADA, the AC Venture Defendants and the ECP Defendants related to the particular Norit Matters for which the Litigation Posting was made.

 

•      Prepayment: ADA may pay to the AC Venture Defendants and/or
Norit any Final Quarterly Royalty Amount at least 10 business days prior to its due date in lieu of having the letter of credit drawn down, in which case the letter of credit will roll over for subsequent Periodic Royalty
Amounts.

		
		 	The Security LC and Periodic LC (including Litigation Postings) may, at ADA’s discretion, be incorporated into a single letter of credit with a single bank provided that all
conditions of both the Security LC and the Periodic LC are complied with and the necessary sums are aggregated in the stated amount.
		
		 	 Any letter of credit provided by ADA pursuant to this Agreement may expire at any time, but will be deemed to be “Continually in
Place” only if such letter of credit is renewed or replaced on terms no less favorable than the existing letter of credit at least thirty days prior to the expiration date of the existing letter of credit.

 
 “Approved Institution”
means a (1) financial institution of national



  
 10 










			
		 	reputation and reasonably satisfactory to the AC Venture Defendants or (2) the Bank of the West in Denver, Colorado; provided, that if the financial institution issuing the letter
of credit(s) suffers an Adverse Rating Event, then within 10 business days of such Adverse Rating Event, ADA shall cause a new Approved Institution selected in accordance with clause (1) to issue the applicable letter of credit(s).
		
		 	“Adverse Rating Event” means that the first to occur of (1) a downgrade in the rating accorded to the financial institution or the financial institution’s
debt securities or long-term debt by any “nationally recognized statistical rating organization”(as defined by the Securities and Exchange Commission for purposes of Rule 436(g)(2) under the Securities Act of 1933, as amended) or
(2) any such organization publicly announces that it has under surveillance or review, with possible negative implications, its rating of the financial institution or the financial institution’s debt securities or long-term
debt.
		
		 	Initial Royalty Payment and Good Faith Estimate: Before the date of this Agreement ADA paid Norit for all royalties past due pursuant to Section 4 of the Final Award,
which is through June 30, 2011. The parties have agreed upon a written good faith forecast of the Periodic Royalty Amount related to the third quarter of 2011, which shall be deemed the initial Periodic Royalty Amount. No later than five
business days after the execution of this Agreement, ADA shall cause the stated amount of the Periodic LC to be no less than the initial Periodic Royalty Amount.
		
		 	Audit Election: Upon reasonable prior notice, but in any event no more than once in any calendar year, until December 31, 2019, ADA may elect, at its sole costs and
expense, to have a nationally or regionally recognized U.S. independent public accountant reasonably satisfactory to the ECP Defendants and the AC Venture Defendants (the “Auditing Accountant”) conduct an audit to verify that the
payments and reports made by ADA or the AC Venture Defendants pursuant to the Final Award are accurate, complete, and in compliance with the terms and conditions of the Final Award, and that, when applicable, royalties have been paid on Gross
Revenues (as defined in the Final Award) for activated carbon in accordance with the terms of the Final Award (in all cases, solely to determine the accuracy of the amount of such payments related to the Existing Carbon Facilities and the division
of such payments between the Existing Carbon Facilities and the New Carbon Facilities). Such examination shall occur at a location or locations on the AC Venture Defendants’ premises reasonably designated by the AC Venture Defendants and shall
not unreasonably interfere with the normal business operations of the AC Venture Defendants. The AC Venture Defendants shall provide the Auditing Accountant with access to all relevant information reasonably requested to conduct the audit.
Information received by the Auditing Accountant pursuant to this paragraph may be designated as “highly


  
 11 










			
		 	confidential” by the AC Venture Defendants and/or the ECP Defendants and such highly confidential information shall be disclosed only to the Auditing Accountant and outside
counsel for ADA and the Auditing Accountant and outside counsel shall agree not to provide such information to ADA, its Subsidiaries and other Affiliates and their respective directors, officers, employees, servants, agents, trustees, insurers,
co-insurers, reinsurers, and shareholders., i.e., “attorneys eyes only.”
		
		 	Auditing Accountant Selection: To maintain the independence of the audit and the confidentiality of the AC Venture Defendants’ information subject to such audit, the
Auditing Accountant selected by ADA (and any persons working for such accountant) shall be bound to keep confidential the details of the AC Venture Defendants’ operations (including, but not limited to, their confidential information and trade
secrets) subject to the audit and to limit the disclosure of the results of any audit to ADA solely to the amount, if any, of a payment adjustment that should be made and whether the adjustment is required due to technical or financial concerns. Any
Auditing Accountant selected by ADA (and any persons working on the audit) shall not have worked for ADA or any Affiliate of ADA other than as an Auditing Accountant (or as a person working for such accountant) under this Agreement for at least 3
years and shall not work for ADA or any Affiliate of ADA for at least 3 years after such audit is completed.
		
		 	Audit Variances and Misallocations: No action shall be taken unless the audit identifies a variance with respect to an amount due to Norit or a misallocation of the royalties
paid pursuant to the Final Award between the Existing Carbon Facilities and the New Carbon Facilities, in both cases, of more than 5% of a Royalty Payment(s) made to Norit. In the event that an audit identifies a variance of an amount due to Norit
of greater than 5%, ADA shall have the right, but not the obligation, to conduct an additional audit pursuant to the procedures in the paragraph titled “Audit Election” in the calendar year in which the discrepancy was discovered. In the
event that the (1) variance resulted from a purely arithmetic error by the AC Venture Defendants in calculating the amount of a Royalty Payment(s) due to Norit (as reasonably agreed by ADA and the AC Venture Defendants) or (2) the AC Venture
Defendants misallocated such royalty payment(s) to the Existing Carbon Facilities, in either case, by more than 5%, the AC Venture Defendants shall pay the amount of such arithmetic error or misallocation and interest on such amount at the Interest
Rate and any related collection efforts within 10 business days of agreement on such amount or an adjudication thereof. The “Interest Rate,” for purposes of this Agreement, means the rate per annum equal to the lesser of
(1) the prime rate as published by the Board of Governors of the Federal Reserve System, as published in statistical release H. 15 or any publication that may supersede it on the day that interest begins to accrue, plus 2 1/2%, and (2) the maximum rate permitted by applicable law. In the
event that the AC Venture Defendants misallocated such royalty payments to


  
 12 










			
		 	 the New Carbon Facilities by more than 5%, ADA shall pay the amount of such misallocation and interest on such amount at the Interest
Rate and any related collection efforts within 10 business days of agreement on such amount or an adjudication thereof. Notwithstanding the foregoing, if ADA is not current with respect to its monetary obligations pursuant to this Agreement,
including to pay the Royalty Payments and with respect to the amount of the Periodic LC (including, without limitation, all Litigation Postings) and the Security LC, then any amounts due by the AC Venture Defendants to ADA pursuant to this paragraph
shall not be paid to ADA and shall instead be off-set against such ADA obligations until the full amount of such ADA obligations are satisfied.
  

In the event that there is a dispute with Norit concerning the royalty amounts due under the Final Award, and notwithstanding the results of any audit
undertaken pursuant to this Agreement, the Parties shall be bound by any final determination of the amount of the Royalty Payments due pursuant to the procedures set forth in the Final Award or as otherwise determined by any panel in the Arbitration
Action.

		
		 	 If the audit identifies any variances other than those resulting from purely arithmetic errors with respect to the amount of royalty
payments due to Norit pursuant to the Final Award resulting from, arising out of or relating to the Existing Carbon Facilities, ADA may, but shall not be obligated, to present the results of such audit to Norit and request that an adjustment be made
to the payments made pursuant to the Final Award. The AC Venture Defendants subject to the royalty payments in the Final Award shall provide reasonable cooperation to ADA in presenting audit results to Norit and subsequently the panel in the
Arbitration Action if ADA cannot reach agreement with Norit and decides to pursue the issue with such panel (which cooperation shall not require such AC Venture Defendants to incur any out of pocket expenses). If ADA is current with respect to its
monetary obligations pursuant to this Agreement, including to pay the Royalty Payments and with respect to the amount of the Periodic LC (including, without limitation, all Litigation Postings) and the Security LC, any amounts received from Norit as
a result of such adjustment shall be paid to ADA. If ADA is not so current, such amounts shall first be paid to the AC Venture Defendants to cure all such deficiencies and then the remaining amount, if any, shall be paid to ADA.

 
 Notwithstanding the results or pendency of any (1) audit, (2) proceeding with or
decision by the panel in the Arbitration Action regarding a dispute over the amount of royalty payments due to Norit pursuant to the Final Award or (3) the adjudication of any miscalculation or misallocation, the Parties shall continue to
perform all their respective obligations pursuant to this Agreement, including ADA’s obligations with respect to the Royalty Payments, the Periodic LC (including, without limitation, all Litigation Postings) and the Security
LC.

	 Security for Royalty
 Payments
	  	Additional Security for Royalty Payments: As additional security for the prompt and complete performance when due of the Royalty Payments, ADA shall post, in
accordance with, and subject to the limitations of, this section, a letter of credit benefiting the AC Venture Defendants obligated to make Royalty Payments (the “Security LC”) containing the following terms:
		
		  	 •      Stated Amount: Calculated
pursuant to this provisions of this section.
  
 •      Beneficiaries: The AC Venture Defendants obligated to make Royalty Payments.

 

•      Issuing Institution: An Approved Institution.

 

•      Drawing: The beneficiaries may draw upon the letter of credit 5
business days after the due date of any Royalty Payment not previously paid by ADA and may draw the full amount of the letter of credit at any time between the 29th day prior to the expiration of the letter of credit and the date of the expiration
of the letter of credit if a new letter of credit has not been provided with terms no less favorable than the existing letter of credit.
  

•      Term: The Security LC must be Continually in Place until at
least the 1 year anniversary of the date the final Royalty Payment is due.

		
		  	This Security LC is in addition to the letter of credit established by ADA for the Periodic Royalty Amount as set forth above under the heading “Prepayment of
Periodic Royalty Amount.”
		
		  	 1. Amount of Security LC: ADA shall establish the Security LC in the minimum aggregate amounts set forth below (the
“Minimum Security LC Amount”) on or before the dates noted. For the avoidance of doubt, amounts stated below are aggregate amounts of the Security LC on such date and are not additional amounts to any existing Security
LC.


  

					
	Date	  	Amount	 
	September 30, 2012	  	$	1,000,000	  
	March 31, 2013	  	$	1,500,000	  
	September 30, 2013	  	$	2,000,000	  
	March 31, 2014	  	$	2,500,000	  
	September 30, 2014	  	$	3,500,000	  
	March 31, 2015	  	$	4,500,000	  
	September 30, 2015	  	$	5,000,000	  
	March 31, 2017	  	$	3,500,000	  
	September 30, 2017	  	$	2,500,000	  


  
 14 










			
		
		 	 At any time when the stated amount of the Security LC exceeds $5,000,000, the stated amount of the Security LC may
be reduced by the amount, if any, of the New Investment Security Amount; provided that in no event shall such reduction cause the stated amount of the Security LC to be less than $5,000,000. By way of example, if the stated amount of the Security LC
equals $6,000,000 and ADA makes a Passive Investment such that the New Investment Security Amount is $2,000,000, ADA may, at its election, reduce the stated amount of the Security LC to $5,000,000 for so long as the New Investment Security Amount
equals or exceeds $1,000,000. The foregoing notwithstanding, if at any date the amount of the Periodic LC and the Security LC when combined exceeds the Remaining Royalty Estimate, ADA may cause the amount of the Security LC to be reduced such that
the amount of the Periodic LC and the Security LC when combined equals or exceeds the Remaining Royalty Estimate.
  

		 	 2. Special Proceeds. Sales of equity in ADA are expressly excluded from this section and “Special Proceeds” as defined below. Subject
to the foregoing exclusion and in addition to the above Minimum Security LC Amounts set forth in paragraph 1, within two (2) business days of receipt by ADA of any net cash and cash equivalent proceeds from (1) the sale, assignment,
transfer, conveyance lease, or other disposal (each, a “Sale Transaction”) of any interest in the Refined Coal Business, (2) any distributions or portion of distributions from the Refined Coal Business resulting from a Sales
Transaction of any asset or assets of the Refined Coal Business in one or a series of related transactions for an amount in excess of $500,000 other than in the ordinary course of business (for purposes of this item (2),“ordinary course of
business” shall include the sale or lease of equipment in the Refined Coal Business) and (3) any Sales Transaction of any asset or assets (including equity interests in any direct or indirect subsidiary, other than the Refined Coal Business,
which is addressed in clause (1) above) in one or a series of related transactions for an amount in excess of $1,000,000 other than in the ordinary course of business, ADA shall apply any and all such net amounts (collectively, the
“Special Proceeds”) as follows:

		
		 	 (A) first, 100% to the AC Venture Defendants until the AC Venture Defendants have been reimbursed for the aggregate amount of all Royalty Payments
funded out of pocket by any of them, or on behalf of any of them, through the date of such allocation (other than via draws upon the Periodic LC or the Security LC provided by ADA under this Agreement) plus interest on each such payment made by the
AC Venture Defendants at the Interest Rate;

		
		 	 (B) second, 100% to fund the Periodic LC (including, without limitation, all Litigation Postings) to the then- required amount to the extent not yet
funded as required by this Agreement;



  
 15 










			
		
		 	 (C) third, 100% to fund/replenish the Security LC to the then-required amount to the extent not yet funded as
required by this Agreement;
  
 (D) fourth, 50% to
increase the stated amount of the Security LC until the aggregate total of all contributions pursuant to this subparagraph (D) equals $10,000,000 or, at any time when the stated amount of the Security LC exceeds $5,000,000, $10,000,000 minus
the New Investment Security Amount (by way of example, if on a certain date, the stated amount of the Security LC equals $6,000,000 and the New Investment Security Amount is $1,000,000, then the Special Proceeds shall be applied pursuant to this
subpart (D) until the aggregate total of all contributions pursuant to this subparagraph (D) equals $9,000,000); provided, that if such increase would cause the stated amount of the Periodic LC and the Security LC when combined to exceed
the Remaining Royalty Estimate, only such portion of such increase shall be made as is necessary to cause such stated aggregate amount to equal the Remaining Royalty Estimate; and

 
 (F) fifth, any remaining Special Proceeds shall be retained 100%
by ADA to be used in its sole discretion.

		
		 	Notwithstanding the foregoing, if any Special Proceeds are derived from the sale of a portion (but not all) of the equity interests in any direct or indirect subsidiary of ADA
pursuant to clause (3) above up to a maximum of $5,000,000 and such amounts are retained in such direct or indirect subsidiary of ADA to capitalize such joint venture between ADA and one or more third parties and such amounts are retained in
such entity to further the business of such entity, subparagraph (D) shall not apply with respect to such Special Proceeds. For the avoidance of doubt, to the extent the amount of such Special Proceeds exceeds $5,000,000, subparagraph
(D) shall still apply with respect to the amount of such Special Proceeds in excess of $5,000,000.
		
		 	 3. Supplemental Security LC Increases Arising from Cash Distributions and Profits of ADA. In the event that ADA declares or otherwise issues a
dividend to any or all of its shareholders or repurchases any equity security from any or all of its shareholders prior to January 1, 2018 (other than repurchases of common stock under employee stock plans), ADA shall, within two business days
of such dividend or repurchase, make a supplemental increase in the stated Security LC amount in an amount equal to 50% of the aggregate fair market value of such dividends or amount spent to repurchase such equity securities (the “Cash
Distribution LC Amount”), such Cash Distribution LC Amount not to exceed



  
 16 










			
		
		 	$7,500,000 in the aggregate. Further, the first time that ADA achieves in a fiscal year ending prior to January 1, 2018 total earnings in excess of $20,000,000 as reported in
its audited year end financial report, ADA shall, within 48 hours of the public disclosure of such earnings, make a one time supplemental increase in the stated Security LC amount of $5,000,000 (the “Profit LC Amount”); provided,
however, that in no event shall the aggregate increase of the stated Security LC amount from all Cash Distribution LC Amount increases and the Profit LC Amount exceed $7,500,000; provided, further, that if any increase in the Security LC amount
provided under this paragraph 3 would cause the aggregate stated amount of the Periodic LC and the Security LC when combined to exceed the Remaining Royalty Estimate, only such portion of such increase to the Security LC shall be made as is
necessary to cause such stated aggregate amount to equal the Remaining Royalty Estimate. For the avoidance of doubt, the aggregate maximum amount of the Security LC is $22,500,000, comprised of the maximum of $5,000,000 required under paragraph 1 as
of August 31, 2015, plus the maximum Security LC increase of $10,000,000 in connection with “Special Proceeds” increases, plus the maximum increase of $7,500,000 required under this paragraph.
		
		 	 4. New Investment Security. If ADA makes a Passive Investment in any New Investment, ADA (1) shall grant the AC Venture Defendants a lien
and security interest on, and shall pledge to the AC Venture Defendants all right, title and interest, whether then owned or thereafter acquired in, to and under, whatever interests ADA receives in connection with such Passive Investment in such New
Investment as additional security for the prompt and complete payment and performance when due of the Royalty Payments, provided that such lien and security shall be released within 10 days after receipt by the AC Venture Defendants of a written
request by ADA, which written request shall be delivered to the AC Venture Defendants no earlier than the date on which the amount of the Periodic LC and the Security LC when combined first equals or exceeds the Remaining Royalty Estimate and
(2) the agreements or other documents governing such Passive Investment in such New Investment shall (A) provide that whenever ADA is to be paid any sum with respect to such Passive Investment in such New Investment, any amounts owed by
ADA to the AC Venture Defendants pursuant to this Agreement shall be deducted from that sum before payment and (B) include a provision substantively similar to Section 12.2(f) (Remedies Upon Indemnity Default) of the ACS LLC Agreement as
it exists as of the date of this Agreement.

		
		 	 5. Drawings on the Security LC. The AC Venture Defendants shall only draw on the Security LC to make Royalty Payments due that have not been
made by ADA. Within 10 business days of any drawing on the Security LC by any AC Venture



  
 17 










			
		  	 Defendant, ADA shall immediately use its best efforts to replenish such security; provided, however, if the aggregate amount
available to the AC Venture Defendants pursuant to the combined Periodic LC and the Security LC stated amounts after such drawing exceeds the aggregate amount of all Royalty Payments to be paid pursuant to the Final Award in the next 12 months, as
reasonably estimated by the AC Venture Defendants, then ADA shall have no less than 120 days to replenish the Security LC.
  

6. Nothing in this Section shall relieve ADA of its obligations pursuant to any other provision of this Agreement or any other
agreement or limit the remedies available to the AC Venture Defendants or the ECP Defendants pursuant to any other provision of this Agreement or any other agreement.
 “New Investment Security Amount” means an amount equal to (1) 50% times (2) the aggregate amount of all Passive Investments in New Investments owned by ADA on a particular
date.
 “Remaining Royalty Estimate” means the aggregate amount of all Royalty Payments remaining to be paid pursuant to the
Final Award, as reasonably estimated by the AC Venture Defendants to be provided by ACS to ADA when reasonably requested on no more than a quarterly basis.
 “Refined Coal Business” means the development, sale, lease or operation of equipment for the control of mercury and NOx in cyclone boilers that qualifies for section 45 tax credits as the
business is currently conducted by, or as may be conducted by, Clean Coal Solutions, LLC.

		
	Extraordinary Transactions	  	Extraordinary Transactions: In the event that ADA (or any of its successors, assigns or direct or indirect subsidiaries in which ADA holds directly or indirectly at least
a fifty percent equity interest (collectively, “Related Parties”)) (1) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, (2) enters
into a Sales Transaction for all or substantially all of its assets with any Person or Persons acting together or constituting a “group” under Section 13(d) of the Exchange Act (a “Group”), (3) enters into a Sale
Transaction for a material portion of its assets with any Person or Group under direct or indirect common control with ADA or any Related Party or (4) undertakes any reorganization, consolidation, restructuring, recapitalization or other change in
its ownership whereby a Person or Group controls more than 50% of ADA’s or any Related Party’s voting securities then, and in each such case, such Related Parties (and their respective successors, assigns and direct and indirect
subsidiaries) shall deliver to the ECP Defendants and the AC Venture Defendants a duly executed joinder or similar binding written undertaking to assume, on a joint and several basis with ADA and any other such Related Party (and their respective
successors, assigns and direct and indirect subsidiaries), the obligations of ADA and the applicable Related Parties under this Agreement.


  
 18 










			
	Release of Certain Known Claims Related to the Existing Actions	  	ECP/ACS Release: In consideration of ADA’s promises in this Agreement, effective immediately, the ECP Defendants and the AC Venture Defendants, each on their own
behalf and on behalf of their predecessors, successors, assigns, parent entities, Subsidiaries, and Affiliates, and each of its past and present directors, officers, partners, members, employees, servants, agents, trustees, insurers, co-insurers,
reinsurers, attorneys, and shareholders (collectively and individually the “ECP/ACS Releasors”) releases, waives, and forever discharges ADA and each of their predecessors, successors, assigns, parent companies, Subsidiaries, and
Affiliates, and each of their past and present directors, officers, partners, members, employees, servants, agents, trustees, insurers, co-insurers, reinsurers, attorneys, and shareholders (collectively, the “ADA Releasees”) from
and against all actions, causes of action, suits, debts, dues, sums of money, accounts, controversies, agreements, promises, injunctive relief, fees, variances, trespasses, damages, judgments, abstracts of judgments, liens, extents, executions,
claims, demands, liabilities, costs, expenses, obligations, contracts, rights to subrogation, rights to contribution, and remedies of any nature whatsoever, in law, admiralty, or equity, in any kind of forum, whether sounding in contract, tort, or
otherwise, that are known or reasonably should have been known by them (collectively, “Claims”), which Claims any or all of the ECP/ACS Releasors ever had, now have or that reasonably should have been known by them (but specifically
excluding those actions, causes of action, suits, debts, dues, sums of money, accounts, controversies, agreements, promises, injunctive relief, fees, variances, trespasses, damages, judgments, abstracts of judgments, liens, extents, executions,
claims, demands, liabilities, costs, expenses, obligations, contracts, rights to subrogation, rights to contribution, and remedies of any nature whatsoever, in law, admiralty, or equity, in any kind of forum, whether sounding in contract, tort, or
otherwise, that were not known or that may not reasonably have been known by them (collectively, “Unknown Claims”)) against any or all of the ADA Releasees, from the beginning of the world until the date of this Agreement, arising
from the Texas Action, the Arbitration Action and the New Jersey Action; provided, however, that the ECP/ACS Releasors do not release ADA from any Claim resulting from, arising out of or relating to (1) the ADA Indemnity Obligations or (2) any
obligation ADA or its Affiliates has pursuant to the ADA/Norit Settlement Agreement, the Final Award (except with respect to breaches by ADA of its obligations pursuant to the Final Award to pay Norit any and all amount due with respect to the New
Carbon Facilities, which shall be ECP/ACS Release Claims Released Claims), the Other Awards or this Agreement (collectively, the “ECP/ACS Released Claims”). Nothing herein shall release or discharge any Claims that any Party may
have in the future for


  
 19 










			
		 	failure to comply with this Agreement. Notwithstanding the foregoing paragraph and the section titled “Additional Legal Fees”, automatically upon the breach and
failure to cure within two business days by ADA of its obligations pursuant to this Agreement with respect (1) to making the Royalty Payments or (2) to funding the Security LC or the Periodic LC (including, without limitation, all Litigation
Postings), the ECP Defendants and the AC Venture Defendants may bring Claims pursuant to the terms of the JDA and this Agreement for Losses (as defined in the JDA) (including, without limitation, any indirect, incidental, punitive, special or
consequential damages whatsoever which in any way arise out of, relate to or are a consequence of such breach by ADA) suffered, incurred or sustained by any of them or to which any of them becomes subject, resulting from, arising out of or relating
to such breach by ADA regardless of when such Losses first arose and the foregoing release shall be deemed null and void ab initio with respect to such Losses (collectively, “Breach Claims”).
		
		 	 ADA Release: In consideration of the ECP Defendants’ and the AC Venture Defendants’ promises in this Agreement,
effective immediately, ADA, on its own behalf and on behalf of its
 predecessors, successors, assigns, parent entities, Subsidiaries, and
Affiliates, and each of its past and present directors, officers, partners, members, employees, servants, agents, trustees, insurers, co-insurers, reinsurers, attorneys, and shareholders (collectively and individually the “ADA
Releasors”) releases, waives, and forever discharges the ECP Defendants and the AC Venture Defendants and each of their predecessors, successors, assigns, parent companies, Subsidiaries, and Affiliates, and each of their past and present
directors, officers, partners, members, employees, servants, agents, trustees, insurers, co-insurers, reinsurers, attorneys, and shareholders (collectively, the “ECP/ACS Releasees”) from and against all Claims, which Claims any or
all of the ADA Releasors ever had, now have or reasonably should have known they had (but specifically excluding the Unknown Claims) against any or all of the ECP/ACS Releasees, from the beginning of the world until the date of this Agreement,
arising from the Texas Action, the Arbitration Action and the New Jersey Action; provided, however, that the ADA Releasors do not release the ECP Defendants or the AC Venture Defendants from any obligation the ECP Defendants, the AC Venture
Defendants and their respective Affiliates has pursuant to the ACS/Norit Settlement Agreement, the Final Award (except with respect to breaches by ACS or RREP of their obligations pursuant to the Final Award to pay Norit any and all amount due with
respect to the Existing Carbon Facilities, which shall be ADA Released Claims) or this Agreement (collectively, the “ADA Released Claims”). Nothing herein shall release or discharge any Claims and any Party may have in the future
for failure to comply with this Agreement.

		
		 	Bar: (1) The ECP/ACS Releasors agree, effective immediately, to


  
 20 










			
		  	 forever waive and forego any right to commence, prosecute, or assert, on their own behalf or on behalf of another, any claims,
cross-claims, or counterclaims in any court or other forum in the United States or elsewhere, against the ADA Releasors, whether arising under state, federal, or foreign law, arising from the ECP/ACS Released Claims and (2) the ADA Releasors agree,
effective immediately, to forever waive and forego any right to commence, prosecute, or assert, on their own behalf or on behalf of another, any claims, cross-claims, or counterclaims in any court or other forum in the United States or elsewhere,
against the ADA Releasors, whether arising under state, federal, or foreign law, arising from the ADA Released Claims; provided, however, in the case of both clause (1) and (2) above, the ECP/ACS Releasors and the ADA Releasors (collectively, the
“Releasors”) do not waive and forego any right to commence, prosecute, or assert any claim, cross-claims, or counter-claims in any court or other forum in the United States or elsewhere, on their own behalf or on behalf of another,
whether arising under state, federal, or foreign law, relating to or arising from this Agreement or any other agreement among any of the Releasors. The Releasors agree that this provision may be enforced by injunction (including an antisuit
injunction) by any ECP/ACS Releasee or ADA Releasee, that the damage caused by such unauthorized claims are incapable of being calculated with certainty, and thus appropriate for injunctive relief. If any court or regulatory body fails to dismiss
the actions or enter the consent judgments as contemplated herein or otherwise modifies the orders of dismissal or consent judgments attached hereto in a manner that changes the legal rights and obligations of the Parties, the release and bar
provided for herein shall operate so as to only permit the Parties to pursue their rights and obligations consistent with this Agreement.
  

Other Losses: Except as expressly set forth in this Agreement regarding Breach Claims, (1) this Agreement supersedes and completely replaces the
Parties’ respective rights and obligations with respect to Losses incurred and indemnification regarding the Norit Litigation under the JDA and the LLC Agreement and (2) nothing in this Agreement shall expand or limit the Parties’
respective indemnification rights and obligations pursuant to the JDA or the ACS LLC Agreement for matters other than the Norit Litigation.

		
	Tolling Arrangement	  	Tolling of Limitations Periods: Any and all statutes of limitations, statutes of repose, contractual time limitations, and any other limitations related to the passage of
time, including, without limitation, laches, estoppel and waiver, applicable to any Breach Claims under common law or under federal, state and/or local statutory law shall be tolled for a period of time commencing on the date hereof and ending on
the expiration of the one year anniversary of the obligations to pay Norit royalties pursuant to the Final Award (the “Tolling Period”). The running of any period of time under any applicable statute of limitations or any other
time-related


  
 21 










					
		  	defense applicable to any Breach Claims shall commence again after the end of the Tolling Period, unless there is an extension of the Tolling Period executed in writing by and on
behalf of the Parties. The Tolling Period shall not be considered in computing any period of time under any applicable statute of limitations or any other time-related defense. The Parties shall not to assert any defense under any applicable statute
of limitations or any other time-related defense except to the extent that such defense is based on periods of time that are not tolled pursuant to this Agreement or any previous tolling agreement among any of the Parties. ADA shall not assert that
the failure of the ECP Defendants or the AC Venture Defendants to commence a proceeding during the Tolling Period gives it any additional grounds for any defense or avoidance with respect to any Breach Claims. By entering into this Agreement, none
of the Parties makes any admissions or representations with regard to the date or dates on which any applicable statute of limitations or other time-related defense may expire or may have expired. This paragraph may not be used as evidence in any
proceeding for any purpose other than to prove that the Parties agreed to a tolling of time-based defenses, as provided herein. Nothing herein does or shall be deemed to preclude the ECP Defendants or the AC Venture Defendants from taking any action
with respect to the Norit Litigation, including, without limitation, the defense and settlement thereof.
		
	Option to Participate in New Projects and Investments	  	 Notice of New Project or Investment: If the ECP Defendants, the AC Venture Defendants or their respective Affiliates and
Subsidiaries seek to pursue any new Project (as defined in the JDA) or other investment in which all or a substantial portion of the revenues are derived from the manufacture and sale of activated carbon (a “New Investment”), such
Person shall present such proposed New Investment to ADA, including a reasonable description of the proposed New Investment and the amount of the proposed investment for an equity or other interest in such New Investment. ADA shall have the option
to make a passive investment in such New Investment as provided below.
  

ADA Option for Passive Investment: ADA shall have the option to elect, by written notice to the Person proposing such New Investment delivered no

interest) basis and in the same form (e.g., common stock, preferred equity or convertible debt) except with respect to voting, control or similar rights, or in such lesser amount determined by ADA, but in any event not less than 25% of the total
economic investment to be made by the Person proposing the proposed New Investment (a “Passive Investment”). For the avoidance of doubt, ADA shall not obtain any voting, control or similar rights in the proposed New Investment but
shall have the option to participate oneconomic terms proportional to the Person proposing the investment.



  
 22 










			
		  	Failure to Respond: If ADA fails to affirmatively elect to invest in such proposed New Investment within such 30-day period, ADA shall be deemed to have affirmatively
declined to participate in such New Investment and the presenting Person shall be free to pursue such proposed New Investment independently or with any other Person.
		
		  	Exclusions from Option: This option and the notice provisions of this section shall not apply to the first facility associated with the Vortex Project.
		
		  	Option is Non-Transferable: ADA shall not assign the option to make a passive investment in a New Investment and any attempt to do so shall be void ab
initio.
		
		  	Termination of Option: ADA’s option to make a passive investment in New Investments shall expire upon the earliest to occur of (the “Expiration
Date”):
		
		  	 •      October 1, 2015;

		  	In addition, ADA’s option to make a passive investment in New Investments shall expire upon the earliest to occur of a Bankruptcy Event or a Failure to Pay occurring prior to
the Expiration Date; provided, however, that within 60 days of the occurrence of any Failure to Pay, ADA’s option shall be reinstated if ADA fulfills its obligations that resulted in the Failure to Pay within 60 days of the occurrence of any
Failure to Pay.
		
		  	“Change of Control” means, with respect to any Person, (a) the sale of all or substantially all of such Person’s assets in one transaction
or series of related transactions, (b) a merger, consolidation, refinancing or recapitalization as a result of which the holders of such Person’s issued and outstanding voting securities immediately before such transaction own or control
less than a majority of the voting securities of the continuing or surviving entity immediately after such transaction and/or (c) the acquisition (in one or more transactions) by any Person or Persons acting together or constituting a
“group” under Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) together with any Affiliates thereof (other than equity holders of such Person as of the date hereof
and their respective Affiliates) of beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) or control, directly or indirectly, of at least a majority of the total voting power of all classes of securities entitled to vote generally

foregoing; or (b) a court of competent jurisdiction enters an order appointing, without consent by ADA, a custodian, receiver, trustee or other officer with similar powers with respect to it or with respect to any substantial part of its property,

dissolution, winding-up or liquidation of ADA, or any such petition shall be filed against ADA and is not dismissed within 60 days.
  

“Failure to Pay” means, with respect to ADA, the failure to pay any payment or provide any indemnification required pursuant to this
Agreement, including, without limitation, any Royalty Payment, when due or the failure to post or replenish any letter of credit required pursuant to this Agreement when due, provided that a “Failure to Pay” shall not occur if ADA makes
such payment, provides such indemnification or posts or replenishes such letter of credit within 30 days of any such failure.

		
	 Drag-Along /Tag-Along
 Rights
	  	Drag-Along and Tag-Along Rights: ADA’s passive investment in any New Investment shall be subject to and shall benefit from drag-along and tag-along rights and
obligations (including indemnification) substantially similar to the rights and obligations of Carbon Solutions Management, LLC as of the date of this Agreement in the ACS LLC Agreement; provided that ADA shall be obligated to make representations

there is a Change in Control of ACS.

at their sole discretion, shall determine from



  
 24

that the limited liability company agreement or similar document of such special purpose entity shall not be amended without ADA’s consent in a manner that:
  

•      Modifies the limited liability of ADA;

 

•      Disproportionately and adversely affects the economic interest of ADA
in such entity; or

		 	 •       Prohibit ADA from selling its ACI equipment and other emission control systems
(as opposed to manufacturing, producing, processing and/or supplying activated carbon) in transactions not involving the sale or supply of activated carbon, including, without limitation, to other equipment or systems suppliers. Notwithstanding the
foregoing, the restrictions in the second bullet under the heading “Non-Compete Obligations” shall still apply.

		
		 	 •       Prohibit ADA from providing consulting services to any end user of ACI or other
emissions control equipment or systems (other than such end users that manufacture, produce, process and/or supply activated carbon) relating to the manufacture, production, processing and/or supply of activated carbon.

or
  

•       purchasing and providing activated carbon to an ADA customer as a
backup for a performance guarantee or otherwise in connection with the sale of an ADA mercury removal technology other than injection of activated carbon (e.g., sale of CyClean technology); provided that

		
		 	 •       if the AC Venture Defendants and their Affiliates have not committed to sell 85%

 26 










			
		  	 their then existing capacity, ADA shall purchase and provide such carbon from the AC Venture Defendants and their Affiliates and the AC Venture
Defendants and their Affiliates agree to quote ADA the lowest price and best terms they have quoted any customer for comparable activated carbon within the previous 6 months; or

		
		  	 •      if the AC Venture Defendants and their Affiliates have committed to sell 85% of
their then-existing capacity, ADA may, at its option (i) accept prices and terms from the AC Venture Defendants and their Affiliates determined in accordance with the immediately preceding bullet or (ii) obtain a quote on price and terms
from another activated carbon supplier and present that quote to the AC Venture Defendants and their Affiliates which will have 10 business days to match such quote whereupon ADA shall be obligated to purchase such carbon from the AC Venture
Defendants and their Affiliates, or, if the AC Venture Defendants and their Affiliates do not match such quote, ADA may purchase such carbon from such other supplier on the prices and terms in such other supplier’s quote.

		
		  	Joint Marketing Efforts and AC Venture Defendants Non-Compete Obligations: Until the earlier of (1) the six month anniversary of the date of this Agreement and
(2) the occurrence of any Bankruptcy Event or Failure to Pay (a) the AC Venture Defendants shall work with ADA and vice versa to jointly market ACI equipment and systems and activated carbon in the North American coal-fired utility market

any Person whereby the AC Venture Defendants or such Person markets or sells such Person’s ACI equipment and systems to any customer in the North American coal-fired utility market.
		
		  	 The foregoing notwithstanding, the AC Venture Defendants Non-Compete Obligations shall not:

		
		  	 •    Prohibit the AC Venture Defendants from entering into any agreement, arrangement or understanding,
including, without limitation, any joint marketing agreement, license or similar agreement with any Person whereby the AC Venture Defendants or such Person markets or sells such Person’s ACI equipment and systems to customers outside of the

 •    Prohibit the
AC Venture Defendants from selling activated carbon in transactions not involving the sale or supply of ACI equipment and other emission control systems, including, without limitation, to other activated carbon manufactures.

		
	 Non-Disparagement
	  	Until the Expiration Date, no Party shall take any action which is intended, or would reasonably be expected, to harm any other Party’s reputation or which would reasonably
be expected to lead to unwanted or unfavorable publicity to such Party provided that nothing herein shall prevent any Party from testifying truthfully in connection with any litigation, arbitration or administrative proceeding when compelled by
subpoena, regulation or court order to do so or from asserting any right that any Party may have against any other Party in any litigation, arbitration or administrative proceeding or making any assertion with respect to any other Party in the Norit

	 Intellectual Property

License Agreement

Amendment
	  	Concurrently with the execution of this Agreement, ADA and ACS shall execute an amendment to the Intellectual Property License Agreement in substantially the form attached hereto
as Exhibit A.
		
	 Confidentiality
	  	Confidentiality Obligations: Each Party (as the “Receiving Party”) agrees that any Confidential Information of the other Party (as the “Disclosing
Party”) received or otherwise obtained in the course of performance under this Agreement shall be kept strictly confidential by the Receiving Party and only disclosed (1) to those employees of the Receiving Party who have a need to know in
order to perform the Receiving Party’s obligations hereunder, except that the Receiving Party may disclose the Disclosing Party’s Confidential Information to any Affiliate of the Receiving Party for the sole purpose of performing the
Receiving Party’s obligations hereunder and administering and enforcing this Agreement, (2) to the Parties’ respective attorneys, accountants, professional advisers, lendors, potential lendors, insurers, trustees and/or other agents who
are required to know of the Settlement Agreement or its terms to carry on the Parties’ business affairs, including, without limitation, any litigation or other actions concerning this Agreement (3) solely with respect to the terms and
conditions of this Agreement, to the limited partners and prospective investors and purchasers of ADA, the ECP


  
 28 










			
		 	Defendants or the AC Venture Defendants or their respective subsidiaries or affiliates and (4) as necessary to comply with any Party’s obligation for public disclosure as a
public company; provided that in all cases of (1), (2) and (3), the Parties shall ensure that any such person is bound by duties or written obligations of confidentiality. The obligation to maintain the confidence of Confidential Information shall
last for 3 years from the date such information was provided to the receiving party except with respect to trade secrets of the disclosing party (which trade secrets will be clearly identified as such), which obligation shall remain in effect for so
long as such information constitutes a trade secret under applicable law. The Receiving Party shall be responsible for any of its Affiliates maintaining (or any failure to maintain) the confidentiality of such Confidential Information of the
Disclosing Party. The Receiving Party further agrees to take the same care with the Disclosing Party’s Confidential Information as it does with its own. Notwithstanding any of the foregoing, the Disclosing Party’s Confidential Information
does not include information that the Receiving Party shows: (x) is or becomes public knowledge without any action by, or involvement of, the Receiving Party or its Affiliates or agents; (y) is independently developed by the Receiving Party without
reference or access to the Confidential Information of the Disclosing Party and is so documented or (z) is obtained by the Receiving Party without restrictions on use or disclosure from a third party who did not receive it, directly or indirectly,
from the Disclosing Party. If the Receiving Party is requested to disclose any of the Disclosing Party’s Confidential Information pursuant to any judicial or governmental order, the Receiving Party will promptly notify the Disclosing Party
(unless such notice is prohibited under applicable law or order) of such order so that the Disclosing Party, in its sole discretion, may seek an appropriate protective order and/or take any other action to prevent or minimize the breadth of such
disclosure; provided that if the Disclosing Party is not successful in precluding the requesting legal body from requiring the disclosure of such Confidential Information, the Receiving Party will furnish only that portion of such Confidential
Information that is legally required and will exercise all reasonable efforts to obtain reliable assurances that confidential treatment will be accorded such Confidential Information. Further, the Receiving Party will provide the Disclosing Party
with reasonable cooperation and assistance in the Disclosing Party’s pursuit of a protective order or other actions to minimize the breadth of such disclosure.
		
		 	“Confidential Information” means (1) all non-public information and material of any Person, including all trade secrets, confidential information, business
and financial information (including pricing information, business and marketing plans and proposals, forecasts, revenues, expenses, earnings projections, customer and supplier lists and information, and sales data), know-how (including
manufacturing and production processes and techniques), research and development information (including discoveries, ideas,
		 	


  
 29 










			
		 	inventions, processes, test data, layouts, designs, tools, samples, formulae, methods, schematics, plans, drawings, data reports, compositions and research records) and (2) the
terms and conditions of this Agreement.
		
		 	Press Releases: Notwithstanding the confidentiality obligations in this Section, upon the execution of this agreement ADA may issue the press release attached hereto as
Exhibit B.

otherwise afforded, will be cumulative and not alternative. 

  
 31 









 Amendment. This Agreement may be amended, supplemented or modified only by a written instrument duly
executed by or on behalf of each of the Parties. 
 Specific Performance. Notwithstanding anything contained herein to the contrary, each
Party to this Agreement acknowledges and agrees that the other Parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached.
Accordingly, each Party to this Agreement agrees that the other Parties shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions
hereof in any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter in addition to any other remedy to which it may be entitled, at law or in equity. 

No Third Party Beneficiary. The terms and provisions of this Agreement are intended solely for the benefit of the Parties hereto and their
respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person other than any Person entitled to indemnification pursuant to this Agreement. 

No Assignment; Binding Effect. Neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party hereto without
the prior written consent of the other Parties hereto and any attempt to do so will be void, except (i) for assignments and transfers by operation of law and (ii) a Party may assign any or all of its rights, interests and obligations
hereunder to a wholly-owned Subsidiary, provided that any such Subsidiary agrees in writing to be bound by all of the terms, conditions and provisions contained herein, but no such assignment referred to in clause (ii) shall relieve such Party
of its obligations hereunder. Subject to the preceding sentence, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties hereto and their respective successors and assigns. 

Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the provisions
hereof. 
 Mutual Drafting. The Parties are sophisticated and have been represented by attorneys throughout the transactions contemplated
hereby who have carefully negotiated the provisions hereof. As a consequence, the Parties do not intend that the presumptions of laws or rules relating to the interpretation of contracts against the drafter of any particular clause should be applied
to this Agreement or any agreement or instrument executed in connection herewith, and therefore waive their effects. 
 Governing Law.
This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to the conflicts of laws principles (whether of the State of Delaware or otherwise) that would result in the application of
the laws of any other jurisdiction. 
 Consent to Jurisdiction and Service of Process; Appointment of Agent for Service of Process. EACH
PARTY TO THIS AGREEMENT HEREBY CONSENTS TO THE JURISDICTION OF ANY UNITED STATES DISTRICT COURT OR THE STATE COURTS OF DELAWARE LOCATED IN WILMINGTON, DELAWARE AND IRREVOCABLY 

  
 32

ACTIONS OR PROCEEDINGS, (2) AGREES THAT IT WILL NOT ATTEMPT TO DENY OR DEFEAT SUCH PERSONAL JURISDICTION BY MOTION OR OTHER REQUEST FOR LEAVE FROM ANY SUCH COURT AND (3) AGREES THAT IT WILL NOT BRING ANY SUCH ACTION OR PROCEEDING IN ANY
COURT OTHER THAN SUCH COURTS. EACH PARTY ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE EXCLUSIVE AND IRREVOCABLE JURISDICTION AND VENUE OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON
CONVENIENS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY NON-APPEALABLE JUDGMENT RENDERED THEREBY IN CONNECTION WITH SUCH ACTIONS OR PROCEEDINGS. A COPY OF ANY SERVICE OF PROCESS SERVED UPON THE PARTIES SHALL BE MAILED BY REGISTERED MAIL TO THE
RESPECTIVE PARTY EXCEPT THAT, UNLESS OTHERWISE PROVIDED BY APPLICABLE LAW, ANY FAILURE TO MAIL SUCH COPY SHALL NOT AFFECT THE VALIDITY OF SERVICE OF PROCESS. IF ANY AGENT APPOINTED BY A PARTY REFUSES TO ACCEPT SERVICE, EACH PARTY AGREES THAT SERVICE
UPON THE APPROPRIATE PARTY BY REGISTERED MAIL SHALL CONSTITUTE SUFFICIENT SERVICE. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW. 
 Waiver of Jury Trial. TO THE MAXIMUM EXTENT PERMITTED BY LAW, EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING
OUT OF THIS AGREEMENT OR ANY DEALINGS AMONG THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED. EACH PARTY ALSO WAIVES ANY BOND OR SURETY OR SECURITY UPON SUCH BOND WHICH MIGHT, BUT FOR THIS WAIVER,

INTO THIS AGREEMENT AND THAT EACH WILL CONTINUE TO RELY ON THE WAIVER IN THEIR RELATED FUTURE DEALINGS. EACH PARTY FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY
WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO 

  
 33 









 THE TRANSACTION CONTEMPLATED HEREBY. IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN
CONSENT TO A TRIAL BY THE COURT. 
 Limitation on Damages. EXCEPT AS PROVIDED IN THE SECTION TITLED “RELEASE OF CERTAIN KNOWN CLAIMS

NONPERFORMANCE BY SUCH PARTY UNDER THIS AGREEMENT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES EXCEPT IN THE CASE OF FRAUD OR TO THE EXTENT SUCH DAMAGES WERE AWARDED TO ANY THIRD PARTY IN CONNECTION WITH A THIRD PARTY CLAIM.

 FOR IMMEDIATE RELEASE 

ADA-ES ANNOUNCES SETTLEMENT WITH ENERGY CAPITAL PARTNERS 
 Company Relinquished Equity in Activated Carbon Plant and Will Make Cash Payments of $3.6 Million 
 to Satisfy Over $30 Million in Claimed Indemnity Obligations 
 Littleton, CO—November
28, 2011—ADA-ES, Inc. (NASDAQ:ADES) (“ADA” or “Company”) today announced that it has entered into an Indemnity Settlement Agreement with Energy Capital Partners LP and its affiliates (“ECP”) and ADA Carbon
Solutions, LLC (“ACS”) and certain of ACS’ affiliates (together the “AC JV Entities”) pursuant to which the parties have agreed to settle certain indemnity claims arising out of the litigation between Norit Americas, Inc.
and Norit International N.V. f/k/a Norit N.V. (collectively “Norit”), ECP and the AC JV Entities in Texas and New Jersey and the related arbitration (collectively, the “Norit Litigation”) based on ADA’s indemnity obligations
under the Joint Development Agreement between ADA and ECP dated as of October 1, 2008. The primary litigation took place before an arbitration panel, which rendered its Final Award in October 2011, confirming the prior settlement agreements
reached with Norit. 
 Pursuant to the Indemnity Settlement Agreement, ADA agreed to settle certain indemnity claims asserted against the
Company for legal fees, costs and expenses arising out of the Norit Litigation in the amount of approximately $33 million and certain other losses. To settle the claims, ADA paid certain AC JV Entities a cash payment of $2.1 million on
November 28, 2011, agreed to $1.5 million in additional payments, agreed to secure the payment of future royalty amounts due to Norit under the Final Award and settlement agreements with Norit through letters of credit and relinquished all of
its 21.3% equity interests in the AC JV Entities which operate an activated carbon (“AC”) plant located in Red River, Louisiana. 
 In
its Form 10-Q for the quarter ended September 30, 2011, ADA reported a net investment in ACS of $7.7 million as of that date and equity interest in ACS’ net loss for the nine months then ended totaling $5.9 million. ADA expects to record
in the fourth quarter of 2011 the transactions resulting from the Indemnity Settlement Agreement for the satisfaction of the indemnity obligations and the relinquishment of its interest in ACS, which will result in other income of approximately
$18.7 million. 
 As part of the agreement, ADA preserves the right for a 49.9% participation, on a passive basis, in AC production lines that
ACS may build in the future. The Company believes that the new Federal regulations to limit mercury emissions from coal-fired boilers, which are scheduled to be made final in December of this year, will create a significant market for additional AC
production lines. 
 Dr. Michael D. Durham, President and CEO of ADA, commented, “We are pleased with the results of this
settlement agreement as it allows us to focus our efforts on the exciting opportunities we have with two different Refined Coal technologies and rapidly developing new markets for our emissions control systems. In response to new and pending
regulations, we are submitting a number of bids for AC injection systems and dry sorbent injection (DSI) equipment. In addition, the option to participate in future AC production plants with ACS and ECP creates an opportunity to further profit from
our position in the mercury control market.” 







 ADA-ES News Release 
 November 28, 2011 
 About ADA-ES 

ADA-ES is a leader in clean coal technology and the associated specialty chemicals, serving the coal-fueled power plant industry. Our
proprietary environmental technologies and specialty chemicals enable power plants to enhance existing air pollution control equipment, minimize mercury, CO2 and other emissions, maximize capacity, and improve operating efficiencies, to meet the challenges of existing and pending
emission control regulations. 
 With respect to mercury emissions: 

 

	 	•	 	 We supply activated carbon (“AC”) injection systems, mercury measurement instrumentation, and related services. 



 

	 	•	 	 Under an exclusive development and licensing agreement with Arch Coal, we are developing and commercializing an enhanced Powder River Basin
(“PRB”) coal with reduced emissions of mercury and other metals. 


  

	 	•	 	 Through our consolidated subsidiary, Clean Coal Solutions, LLC (“CCS”), we provide our patented refined coal technology, CyClean, to enhance
combustion of and reduce emissions from burning PRB coals in cyclone boilers and expect to provide our patent pending refined coal technology M-45 which both reduce emissions of NOx and mercury in coal fired boilers. 



In addition, we are developing CO2 emissions technologies under projects funded by the U.S. Department of Energy (“DOE”) and industry participants.

 This press release includes forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934,
which provides a “safe harbor” for such statements in certain circumstances. The forward-looking statements include statements or expectations regarding the creation of additional markets for AC through Federal regulation, timing of
finalization of the Federal regulations to limit mercury emissions from coal-fired boilers, expected accounting treatment of the settlement and the opportunity for future profits from participation in future AC production plants and our position in
the mercury control market. Actual events or results could differ materially from those discussed in the forward-looking statements as a result of various factors, including but not limited to, changes in laws and regulations, availability of
government funding, prices, economic conditions and market demand, timing and impact of new and pending laws and regulations and any legal challenges to them, the impact of competition, availability, cost of and demand for alternative energy sources
and other technologies, technical, start-up and operational difficulties, inability to commercialize our technologies on favorable terms; our inability to ramp up our operations to effectively address expected growth in our target markets,
availability of raw materials and equipment for our businesses; loss of key personnel, intellectual property infringement claims from third parties; and other factors that we discuss in greater detail in our filings with the Securities and Exchange
Commission (SEC). You are cautioned not to place undue reliance on our forward-looking statements and to consult filings we make with the SEC for additional risks and uncertainties that may apply to our business and the ownership of our securities.
Our forward-looking statements are presented as of the date made, and we disclaim any duty to update such statements unless required by law to do so.
