( e) In the event Lender has determined to honor a drawing under a Letter of Credit, Lender shall promptly notify Borrower of the amount paid by Lender and the date on which such payment is to be made to such beneficiary.

Any payment due from Borrower with respect to the Letter of Credit not paid on the required date shall thereafter bear interest at the Default Rate. (f) Notwithstanding the foregoing, Lender shall not be under any obligation to issue any Letter of Credit if at the time of such issuance, any order, judgment or decree of any governmental authority or agency or arbitrator shall purport by its terms to enjoin a restraining Lender from issuing a Letter of Credit or any statute, law, rule, regulation or other legal requirement applicable to Lender or any request or directive (whether or not having the force of law) from any such governmental authority or agency shall prohibit the issuance ofletters of credit generally or the Letter of Credit in particular or shall impose upon Lender with respect to the Letter of Credit any restriction or reserve or capital requirement (for which Lender is not otherwise compensated) not in effect on the date of closing of the Loan.

Notwithstanding the foregoing, Lender will not use this power of attorney to renegotiate the term of any agreement between either of Borrower or ADES and any third party. ARTICLE IX INDEMNIFICATION 9 .1 Indemnification by Borrower. Borrower shall indemnify and hold harmless Lender, and each of Lender's assignees, each of Lender Affiliates and each of their respective directors, officers, shareholders and employees (each an "Indemnified Party") from and against any and all liabilities, damages, penalties, expenditures, losses, or charges, which are incurred by, or awarded or assessed against, any Indemnified Party arising out of, or resulting from: (a) any fraud by Borrower, including the misappropriation of any material portion of the Collateral or any of the proceeds thereof (other than an unintentional misappropriation of Collateral so long as such unintentional misappropriation is cured within three (3) Business Days of Borrower's knowledge of such misappropriation); (b) any representation or warranty of Borrower contained in Article V hereof which shall have been false or incorrect in any material respect on and as of the date made (all of the foregoing, collectively, the "Indemnified Liabilities"); provided, however, that, in each of (a) or (b) above, no Indemnified Party shall have the right to be indemnified for its own fraud, bad faith, gross negligence or willfully improper action or inaction. 9.2 Indemnification Procedure. Any claim for indemnification under this Article IX must be asserted by Lender by giving written notice to Borrower of the matter with respect to which Lender seeks to be indemnified (a "Claim") within a reasonable time after Lender has knowledge of facts forming a sufficient basis for said Claim, stating the nature of said Claim and, if known, the estimated amount of the loss, cost or expense. Lender and each Indemnified Party will give Borrower sole authority and control of the defense and settlement of the Claim and, at Borrower's request and expense, cooperate with Borrower in the defense and settlement of the Claim. Once Borrower has assumed the defense or settlement of a Claim, if Lender or any Indemnified Party wishes to obtain or maintain its own counsel or other professional assistance it shall do so at its own expense. Notwithstanding anything to the contrary contained in this section, Borrower will not have any obligation to indemnify or hold Lender or any Indemnified Party harmless for Lender's or such Indemnified Party's own grossly negligent or willfully improper actions or inactions. Borrower shall carry out its indemnification obligation through counsel selected by Borrower which counsel shall be acceptable to Lender, in Lender's reasonable judgment. Borrower will not make any settlement or other resolution of a Claim or enter into any obligation which would be binding upon Lender without Lender's consent, exercised in Lender's reasonable judgment. DEC-1770697-10 23

 
9.3 Limitation on Indemnification. Notwithstanding anything to the contrary contained in this section, Borrower will not have any obligation to indemnify or hold Lender or any Indemnified Party harmless for incidental, consequential, punitive or exemplary damages, including without limitation, lost profits or revenue not directly related to this Agreement. 9 .4 Survival.

Lender shall have no obligation to take, and Borrower shall have the sole responsibility for taking, any and all steps to preserve rights against any and all of Borrower's Account debtors and against any and all prior parties to any note, chattel paper, draft, trade acceptance, or other instrument for the payment of money covered by Lender's Security Interest in the Collateral whether or not in Lender's possession.

Without limiting any other right of Lender, whenever Lender has the right to declare any Indebtedness to be immediately due and payable (whether or not it has so declared), Lender, at its sole election, may set off against the Indebtedness any and all monies then due and owing to Borrower by Lender in any capacity, and Lender shall be deemed to have exercised such right of setoff immediately at the time of such election even though any charge therefor is made or entered on Lender's records subsequent thereto. 10.6 Assignment. The rights and benefits of Lender hereunder shall inure to any party acquiring any interest in the Indebtedness or any part thereof, provided such assignee agrees in writing to be bound by the terms hereof.

Lender and Borrower, as used herein, shall include the successors or assigns of those parties, except that Borrower shall have no right to assign its rights hereunder or any interest herein without the written consent of Lender. 10.8 Modification, Waiver. No modification or amendment of any provision of this Agreement shall be made, except by a written agreement signed by Borrower and Lender. Lender shall not be deemed to have waived any rights under this Agreement unless such waiver is given in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall operate as a waiver of such right or any other right. A waiver by Lender of any provision of this Agreement shall not prejudice or constitute a waiver of Lender's rights otherwise to demand strict compliance with that provision or any other provision of this Agreement. No prior waiver by Lender, or any course of dealing between Lender and Borrower shall constitute a waiver of any of Lender's rights or of any obligations of Borrower as to any future transactions. Whenever the consent of Lender is required under this Agreement, the granting of such consent by Lender in any instance shall not constitute continuing consent in subsequent instances where such consent is required, and in all cases such consent may be granted or withheld in the sole discretion of Lender. 10.9 Counterparts. This Agreement may be executed in any number of counterparts, and by Lender and Borrower on separate counterparts, each of which, when so executed and delivered, shall be an original, but all of which shall together constitute one and the same Agreement. 10.10 Termination. This Agreement is, and is intended to be, a continuing Agreement and shall remain in full force and effect until the full and final payment of all of the Indebtedness; provided, however, that Borrower, subject to the provisions hereof which expressly survive termination, may terminate this Agreement at any time by giving Lender at least five (5) Business Days prior notice of termination in writing whereupon all outstanding Indebtedness shall be due and payable in full without presentation, demand, or further notice of any kind, whether or not all or any part of such Indebtedness is otherwise due and payable DEC-1770697-10 25
